Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021.

Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies.

These diseases result from an interaction between the environment and genetically predisposed individuals. This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf."

"abstract_text": "ID: 42345500\nTitle: Formaldehyde neurotoxicity: Effects on the mammalian brain, cognitive function, and neurodegenerative risk. A scoping review.\nAbstract: Aqueous formaldehyde (FA) solution, known as formalin, is currently the primary agent used for preserving tissue samples and anatomical specimens. Formaldehyde is widely used in laboratories and the chemical industry; it also occurs as an air pollutant and endogenous cellular metabolite. The potential carcinogenic effects of formalin on the respiratory tract are well documented. A less recognized consequence of occupational exposure to FA is its detrimental effect on the central nervous system (CNS) and brain function. A literature review was conducted to investigate the effects of FA on the brain. Five databases were searched: PubMed, Web of Science (WoS), Embase, ScienceDirect, and Google Scholar. To describe the effects of FA exposure and endogenous FA generation, 35 relevant publications were collected and analyzed. The literature review demonstrated that inhalation is the most common route of FA exposure. Several studies have shown that FA may cause hippocampal damage, disrupt melatonin secretion, and induce a wide range of cognitive disorders with varying characteristics and severity. These disorders include memory impairment, disturbances in balance and spatial orientation, learning difficulties, sleep disturbances, impaired judgment, and prolonged reaction times to stimuli. Increased endogenous FA concentration has also been associated with a higher risk of neurodegenerative diseases, such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis. The literature analysis demonstrated the high neurotoxicity of FA, which may lead to numerous neuropsychiatric disorders. We aim to draw attention to the risks associated with the routine use of formalin, particularly among anatomists and pathologists, and to encourage consideration of less harmful alternative preservation agents."

Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases."

Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS."

ECAS-Cognitive and -Carer Interview (ECAS-C/-CI) scores of N\u2009=\u2009901 patients with ALS without a formal diagnosis of dementia were retrospectively retrieved. Patients were classified, pursuant to Strong et al.'s criteria, as cognitively and behaviourally normal (ALScbn), cognitively and/or behaviourally impaired (ALSci/bi/cbi), or Possible ALS-FTD, according the following ECAS-based algorithms: (1) Abrahams', solely addressing ECAS-C total and ALS-Specific subtotals; (2) Poletti et al.'s, addressing single task-level ECAS-C scores; (3) \"Subscale\", addressing ECAS-C subscales (i.e., Language, Executive, Fluency, Memory and Visuospatial). All algorithms relied on single-item-level ECAS-CI scores for behavioural classifications. Whilst agreement rates among these classifications were moderate to high (84-86%; Cohen's k\u2009=\u20090.78-0.81), and some discrepancies emerged: (1) \"ALScbn-to-ALSci\" and \"ALSci-to-ALScbn\" re-classifications occurred across the three comparisons, ranging from\u2009~\u200911% to\u2009~\u200924%; (2) the most classificatory disagreements (~\u200943%) occurred for the ALScbi category when comparing single task-level (Poletti) to total-level (Abrahams) algorithms, with patients being re-classified as either ALSbi or Possible ALS-FTD; (3)\u2009~\u200924% of Abraham's Possible ALS-FTD cases were re-classified as either ALScbi or ALSbi by the Subscale approach. Different ECAS-based algorithms for deriving Strong's phenotypes might yield slight discrepancies that could under- or overestimate a given classification."

It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40\u2009Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3\u2009Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS."

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies."

Using a SASP reporter combined with a CRISPR-Cas9 screen targeting active regulatory elements, we identify the zinc-finger protein ZNF512B as a key suppressor of the SASP. ZNF512B loss induces DNA damage, activates cGAS-STING signaling, and triggers inflammatory transcriptional reprogramming. In contrast, ZNF512B promotes preferential DNA repair at regulatory genomic regions, limiting SASP induction. Mechanistically, ZNF512B is rapidly recruited to DNA-damage sites via distinct zinc-finger domains and facilitates NuRD complex targeting to damaged chromatin, enabling precise repair. In human neuromuscular organoids, ZNF512B deficiency induces inflammation, lineage imbalance, and cytokine secretion resembling amyotrophic lateral sclerosis (ALS)-associated pathology. In vivo, ZNF512B overexpression reduces DNA damage and inflammation following acute liver injury. Together, these findings support a mechanism of preferential DNA repair that contributes to maintaining genome integrity, suppressing SASP and inflammation."

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS."

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."

All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort.

However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3\u00a0Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments."

While the crude incidence of both PD and MS remained nearly stable over time (PD: incidence rate ratio [IRR] per year = 0.998, p < 0.001; MS: IRR = 0.992, p < 0.001), the standardized incidence showed a more marked decrease for PD (IRR = 0.986, p < 0.001) while remaining almost unchanged for MS (IRR = 0.995, p < 0.001). For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001). Life expectancy at diagnosis of PD increased between 2003 and 2013 (+0.95 months per calendar year, p < 0.001) and then decreased between 2013 and 2022 (-1.20 months, p = 0.002), while it increased significantly over the entire study period for MS (+2.35 months, p < 0.001) and MNDs (+0.34 months, p = 0.01). These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence.

This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf."

Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions."

Patient responses to treatments vary widely, highlighting the need for personalized care. Clustering patients based on disease progression could improve prognosis, guide clinical decision-making, and optimize clinical trial design. This study aimed to identify robust ALS patient clusters using ALS Functional Rating Scale-Revised (ALSFRS-R) scores and to determine diagnostic parameters predictive of cluster membership, enabling earlier stratification and targeted management. Data from the Tours ALS center registry (April 1997-October 2023) were analyzed; after preprocessing, 353 patients monitored every three months between January 2004 and July 2023 with ALSFRS-R, clinical, biological, and demographic data were retained. After preprocessing to handle missing or aberrant data, a weakly supervised approach labeled patient pairs based on their ALSFRS-R sequences. These labels were used to train a classifier to learn a distance for off-the-shelf clustering algorithms. Multiple configurations were tested, varying clustering algorithms, dimensionality reduction method, and number of clusters. Random Forest (RF) model predicted cluster membership from diagnostic parameters. Optimal clustering was selected using silhouette score, validated with Kaplan-Meier survival analysis. Stability and robustness were assessed with the Adjusted Rand Index (ARI) and silhouette score respectively. Predictive performance was evaluated using specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV). Diagnostic parameters associated with clusters were identified using Kruskal-Wallis and chi-squared tests for continuous and categorical variables. Three clusters (n\u2009=\u2009139, 121, 93) were identified, demonstrating strong separation (silhouette\u2009\u2248\u20090.6) and high stability of results (ARI\u2009\u2248\u20090.7). Survival differed significantly among clusters: over 50% of patients in the third cluster survived beyond 50 months, compared to less than 25% in the other clusters. Thirteen diagnostic parameters-including ALSFRS-R subscores, IgG levels, albumin quotient, and time to diagnosis-were key predictors of cluster membership. Cluster prediction achieved specificity and NPV\u2009\u2248\u20090.75, with close sensitivity and PPV compared to state-of-the-art methods. This framework successfully stratifies ALS patients into clinically meaningful clusters, revealing underlying disease heterogeneity and providing strong prognostic insight. Such classification can facilitate personalized care, guide therapeutic decisions, and inform the design of targeted interventions to improve outcomes. Not applicable."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations."

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

With limited treatment options, identifying modifiable risk factors that impact ALS survival is an important goal. Air pollution may be one such risk factor, yet the research on this topic is limited. METHODS: We assessed survival for ALS patients at the University of Michigan Pranger ALS Clinic who were recruited to participate in a prospective cohort study between 2009 and 2022. Participants\u2019 personal characteristics were linked with residential air pollutant levels of fine particulate matter mass (PM2.5), nitrogen dioxide (NO2), and ozone (O3), as well as several particle components, including black carbon (BC), nitrate, sulfate, and sea-salt (as a negative control) over follow-up. To assess the role of air pollution on ALS mortality we used time-dependent Cox proportional hazards models with days from diagnosis as the time axis, adjusted for potential confounders and co-pollutants. RESULTS: Across the 1,276 total years of person-time during follow-up (2.7\u2009\u00b1\u20092.5 years per participant) there were 329 deaths. In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1\u00a0\u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death. The other pollutants were not associated with death in participants with ALS . CONCLUSIONS: This finding suggests a seven month longer median survival for a 2.1\u00a0\u00b5g/m3 decrease in 1-year average PM2.5, which is significant given that ALS lacks a cure and that existing treatments only extend survival by a few months."

It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants."

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS."

While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies."

"abstract_text": "ID: 42304913\nTitle: Nicotine Versus Non-Nicotine Constituents in Neurodegenerative Risk: Evidence from Multivariable Mendelian Randomization.\nAbstract: Nicotine has complex neuropharmacological actions through nicotinic acetylcholine receptors, but its independent role in neurodegenerative diseases remains unclear because tobacco smoke contains many non-nicotine toxicants. This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50). Exposure to nicotine can increase the risks of AD, while conferring protective effects against tremor and EC. Furthermore, exposure to non-nicotine tobacco constituents acts as a risk factor for the incidence of EC."

Here, we have profiled motor neuron microRNAs (miRNAs) during motor neuron degeneration in vivo to gain a better understanding of ALS pathophysiology. We demonstrate that one miRNA, miR-146a, is downregulated in diseased motor neurons despite upregulation in bulk tissue. Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed. Finally, we observed that a proportion of miR-146a knockout animals develop spontaneous paralysis, motor neuron loss and chronic neuroinflammation with advanced age. Together these findings demonstrate that a single miRNA influences multiple aspects of motor neuron disease and highlights the complex role for neuroinflammation in ALS pathogenesis."

SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies."

These demands place substantial strain on family carers and often require input from paid homecare workers. Despite their essential role, little is known about how homecare workers contribute to complex MND care, how they integrate within multidisciplinary teams, or how families experience their involvement. To examine people living with MND and family members' perspectives of homecare worker roles, responsibilities, relationships when complex interventions are required. A qualitative secondary analysis of data from two prior studies exploring home ventilation and tracheostomy ventilation in MND. Seven relevant NVivo nodes and 33 sub-nodes from interviews with 68 participants were re-coded using a deductive framework. Fourteen new nodes and 11 sub-nodes were generated and organised into three themes: care commissioning and provision; relationships; and the home environment. Participants described fragmented and inconsistent care commissioning, requiring families to advocate persistently for adequate support. Challenges included funding barriers, high staff turnover, and limited MND-specific knowledge, which undermined trust and compromised safe, effective care. Relationships with homecare workers ranged from highly valued, stable partnerships to strained interactions shaped by competence concerns, emotional labour, and mismatched expectations. The presence of homecare workers and medical equipment transformed the home into a quasi-clinical space, reducing privacy, disrupting routines, and requiring households to adapt around care provision. Yet strong relationships with homecare workers could enhance quality of life. Homecare workers play a critical role in delivering complex home-based MND care, yet quality is inconsistent. Improving training, stabilising staffing, supporting care coordination, and preparing families for the relational and environmental impact of homecare are essential for fostering sustainable, trusted care relationships, and improving outcomes for people living with MND and their families. Paid homecare support for people with motor neurone disease: Insights from people with MND and their families This study explores how people living with motor neurone disease (MND), and their family members, experience support from paid homecare workers when complex medical interventions, such as ventilation, feeding tubes, suction and hoists are needed at home. As care needs increase, families often need help from paid homecare workers, yet no research has asked families about what this support is like. To address this, we re-analysed interview data from two earlier studies about living with home ventilation in MND, and developed three main themes: Care commissioning and provision: Participants described the process of securing a care package as confusing and often exhausting, with multiple organisations involved. Families frequently had to push to get the support they needed. Problems included shortages of trained staff, high staff turnover, and delays caused by complex funding rules. Relationships with homecare workers: Good homecare workers made a huge positive difference. Relationships with homecare workers ranged from highly positive, built on trust, skill and becoming \u2018part of the family\u2019, to strained, particularly when workers lacked MND-specific training or confidence with equipment. Trust was crucial: when present it eased pressure on families but when absent it increased stress and vigilance. Impact on the home environment: Having carers in the house, changed home life, reducing privacy, disrupting household routines, and living spaces became filled with medical equipment and ever-present homecare workers. Families described feeling like hosts in their own homes and sometimes having to manage the emotional labour of being polite or accommodating even when exhausted. Overall, the study shows that homecare workers play an essential role in complex MND care, but quality is inconsistent. Better coordination and support for families to manage these close relationships within the home are vital to reduce pressure on families and improve quality of life."

People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170\u00a0h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected."

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease."

While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients."

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies.

With limited treatment options, identifying modifiable risk factors that impact ALS survival is an important goal. Air pollution may be one such risk factor, yet the research on this topic is limited. METHODS: We assessed survival for ALS patients at the University of Michigan Pranger ALS Clinic who were recruited to participate in a prospective cohort study between 2009 and 2022. Participants\u2019 personal characteristics were linked with residential air pollutant levels of fine particulate matter mass (PM2.5), nitrogen dioxide (NO2), and ozone (O3), as well as several particle components, including black carbon (BC), nitrate, sulfate, and sea-salt (as a negative control) over follow-up. To assess the role of air pollution on ALS mortality we used time-dependent Cox proportional hazards models with days from diagnosis as the time axis, adjusted for potential confounders and co-pollutants. RESULTS: Across the 1,276 total years of person-time during follow-up (2.7\u2009\u00b1\u20092.5 years per participant) there were 329 deaths. In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1\u00a0\u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death. The other pollutants were not associated with death in participants with ALS . CONCLUSIONS: This finding suggests a seven month longer median survival for a 2.1\u00a0\u00b5g/m3 decrease in 1-year average PM2.5, which is significant given that ALS lacks a cure and that existing treatments only extend survival by a few months."

The most common subtype, amyotrophic lateral sclerosis (ALS), is characterized by both upper and lower motor neuron impairment, which can manifest clinically in the bulbar region or asymmetrically in a limb. Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care. We share our perspective on how the ALS Africa Network is coordinating a shift in the African MND landscape to improve patient care."

"abstract_text": "ID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants."

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS."

While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies."

We demonstrate that one miRNA, miR-146a, is downregulated in diseased motor neurons despite upregulation in bulk tissue. Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed. Finally, we observed that a proportion of miR-146a knockout animals develop spontaneous paralysis, motor neuron loss and chronic neuroinflammation with advanced age. Together these findings demonstrate that a single miRNA influences multiple aspects of motor neuron disease and highlights the complex role for neuroinflammation in ALS pathogenesis."

SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies."

These demands place substantial strain on family carers and often require input from paid homecare workers. Despite their essential role, little is known about how homecare workers contribute to complex MND care, how they integrate within multidisciplinary teams, or how families experience their involvement. To examine people living with MND and family members' perspectives of homecare worker roles, responsibilities, relationships when complex interventions are required. A qualitative secondary analysis of data from two prior studies exploring home ventilation and tracheostomy ventilation in MND. Seven relevant NVivo nodes and 33 sub-nodes from interviews with 68 participants were re-coded using a deductive framework. Fourteen new nodes and 11 sub-nodes were generated and organised into three themes: care commissioning and provision; relationships; and the home environment. Participants described fragmented and inconsistent care commissioning, requiring families to advocate persistently for adequate support. Challenges included funding barriers, high staff turnover, and limited MND-specific knowledge, which undermined trust and compromised safe, effective care. Relationships with homecare workers ranged from highly valued, stable partnerships to strained interactions shaped by competence concerns, emotional labour, and mismatched expectations. The presence of homecare workers and medical equipment transformed the home into a quasi-clinical space, reducing privacy, disrupting routines, and requiring households to adapt around care provision. Yet strong relationships with homecare workers could enhance quality of life. Homecare workers play a critical role in delivering complex home-based MND care, yet quality is inconsistent. Improving training, stabilising staffing, supporting care coordination, and preparing families for the relational and environmental impact of homecare are essential for fostering sustainable, trusted care relationships, and improving outcomes for people living with MND and their families. Paid homecare support for people with motor neurone disease: Insights from people with MND and their families This study explores how people living with motor neurone disease (MND), and their family members, experience support from paid homecare workers when complex medical interventions, such as ventilation, feeding tubes, suction and hoists are needed at home. As care needs increase, families often need help from paid homecare workers, yet no research has asked families about what this support is like. To address this, we re-analysed interview data from two earlier studies about living with home ventilation in MND, and developed three main themes: Care commissioning and provision: Participants described the process of securing a care package as confusing and often exhausting, with multiple organisations involved. Families frequently had to push to get the support they needed. Problems included shortages of trained staff, high staff turnover, and delays caused by complex funding rules. Relationships with homecare workers: Good homecare workers made a huge positive difference. Relationships with homecare workers ranged from highly positive, built on trust, skill and becoming \u2018part of the family\u2019, to strained, particularly when workers lacked MND-specific training or confidence with equipment. Trust was crucial: when present it eased pressure on families but when absent it increased stress and vigilance. Impact on the home environment: Having carers in the house, changed home life, reducing privacy, disrupting household routines, and living spaces became filled with medical equipment and ever-present homecare workers. Families described feeling like hosts in their own homes and sometimes having to manage the emotional labour of being polite or accommodating even when exhausted. Overall, the study shows that homecare workers play an essential role in complex MND care, but quality is inconsistent. Better coordination and support for families to manage these close relationships within the home are vital to reduce pressure on families and improve quality of life."

People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170\u00a0h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected."

This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50). Exposure to nicotine can increase the risks of AD, while conferring protective effects against tremor and EC.

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease."

To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis.

This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis.

While age-standardized rates have shown decline in certain regions, the absolute number of cases is escalating due to the interplay of global aging and population growth.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis (ALS) is increasingly recognized as a fatal neurodegenerative disease with a global epidemiology characterized by complex variations across age, sex, and geography. Current research indicates that the apparent rise in ALS cases is driven by demographic change. As global populations age, the number of individuals entering the age range of peak incidence (70\u201379 years) increases, leading to a higher total disease burden despite potentially stable or declining age-standardized rates. This demographic transition is particularly evident in studies analyzing longitudinal trends. Furthermore, the role of environmental factors and genetic susceptibility in a predisposed population continues to be investigated as a secondary driver of the disease landscape.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Population aging accounted for 46.0% of the increase in DALYs in China from 1990 to 2021.\n* Age-standardized rates of motor neuron disease have declined in many settings despite rising absolute numbers.\n* The global pooled incidence of ALS is 1.65 per 100,000 person-years.\n* Incidence and prevalence of ALS are significantly lower in females than in males.\n* ALS burden is higher in high-income countries compared to middle-income countries.\n* There is a marked age-dependent pattern for ALS burden, peaking at ages 70-79.\n* Environmental exposure to toxic metals (lead, cadmium, mercury) and chemicals like formaldehyde is linked to neurodegenerative risk.\n* The gut-microbiota-brain axis and dietary factors, including vitamin intake, are increasingly implicated in ALS progression.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This phenomenon is primarily driven by demographic factors\u2014specifically population ageing and growth\u2014rather than an increase in per-capita disease risk.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe perceived surge in ALS prevalence is a multifaceted epidemiological outcome. Demographic studies conducted over the last two decades provide compelling evidence that the escalation in case numbers is largely a byproduct of an ageing global population. Because ALS incidence peaks at ages 70\u201379, the demographic shift toward longer life expectancies disproportionately increases the size of the high-risk cohort. Furthermore, improved clinical management, such as the use of gastrostomy for nutritional support and better multidisciplinary care, has increased survival rates, thereby inflating the total number of individuals living with the disease at any given time. While environmental factors, genetic risks, and potential changes in ascertainment exist, current meta-analytical evidence suggests that the rising prevalence of motor neuron diseases reflects a true increase in absolute cases driven by demographic expansion and enhanced longevity post-diagnosis.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Population ageing accounts for approximately 46% of the increase in disability-adjusted life years (DALYs) in MND-related studies.\n* Age-standardized rates of MND have actually declined in many settings, suggesting that individual risk may be stable or decreasing.\n* Gastrostomy interventions like PEG or RIG, while primarily nutritional, have been shown to increase survival rates for ALS patients.\n* The global incidence of ALS is 1.65 per 100,000 person-years, with a notably higher disease burden in high-income countries compared to middle-income settings.\n* There is a significant sex disparity in ALS burden, with prevalence rate ratios indicating a lower burden in females compared to males.\n* Improved multidisciplinary palliative care facilitates better referral and intervention timing, indirectly contributing to the survival-driven increase in prevalence.\n* Environmental exposures and dietary factors are increasingly linked to the pathogenesis, suggesting that \"epidemiological shifts\" are complex and interact with demographic changes.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature indicates that while age-standardized rates have declined in some regions, the absolute global burden of ALS is rising, primarily driven by demographic factors like population aging, population growth, and potentially true increases in incidence in certain populations.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe increasing global burden of ALS is a multifactorial phenomenon. While demographic shifts (aging and population growth) account for a significant portion of the absolute increase in cases, evidence suggests that for MNDs, there is a documented increase in both crude and standardized incidence, distinguishing it from other neurodegenerative conditions where prevalence rises are survival-driven.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe epidemiological landscape of Amyotrophic Lateral Sclerosis (ALS) demonstrates a divergence between age-standardized rates and absolute disease burden. Recent analyses indicate that \"Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%).\" This reflects a broader trend where \"Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially.\" Notably, epidemiological patterns for MNDs appear distinct from other neurodegenerative conditions, as \"These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence.\" This is supported by data stating \"For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001).\" While research into causes is ongoing, environmental factors remain a focus, with studies suggesting that \"In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1 \u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Global prevalence of ALS is estimated at 5.05 per 100,000 population.\n* The disease burden is significantly higher in high-income countries compared to middle-income nations.\n* Male individuals consistently show a significantly higher disease burden than females, with prevalence rate ratios around 0.69.\n* Diagnostic yield for pathogenic variants in ALS is approximately 15.90%, with higher yields (36.95%) in familial cases.\n* Tofersen treatment for SOD1-ALS marks a shift toward functional recovery modeling, creating a new \"Recovery Model System of Care.\"\n* Air pollution (PM2.5) exposure is associated with increased mortality in ALS patients.\n* ALS incidence peaks in the 70-79 age range.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations."

These diseases result from an interaction between the environment and genetically predisposed individuals. This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf."

A scoping review.\nAbstract: Aqueous formaldehyde (FA) solution, known as formalin, is currently the primary agent used for preserving tissue samples and anatomical specimens. Formaldehyde is widely used in laboratories and the chemical industry; it also occurs as an air pollutant and endogenous cellular metabolite. The potential carcinogenic effects of formalin on the respiratory tract are well documented. A less recognized consequence of occupational exposure to FA is its detrimental effect on the central nervous system (CNS) and brain function. A literature review was conducted to investigate the effects of FA on the brain. Five databases were searched: PubMed, Web of Science (WoS), Embase, ScienceDirect, and Google Scholar. To describe the effects of FA exposure and endogenous FA generation, 35 relevant publications were collected and analyzed. The literature review demonstrated that inhalation is the most common route of FA exposure. Several studies have shown that FA may cause hippocampal damage, disrupt melatonin secretion, and induce a wide range of cognitive disorders with varying characteristics and severity. These disorders include memory impairment, disturbances in balance and spatial orientation, learning difficulties, sleep disturbances, impaired judgment, and prolonged reaction times to stimuli. Increased endogenous FA concentration has also been associated with a higher risk of neurodegenerative diseases, such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis. The literature analysis demonstrated the high neurotoxicity of FA, which may lead to numerous neuropsychiatric disorders. We aim to draw attention to the risks associated with the routine use of formalin, particularly among anatomists and pathologists, and to encourage consideration of less harmful alternative preservation agents."

Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases."

Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS."

It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40\u2009Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3\u2009Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS."

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies."

Using a SASP reporter combined with a CRISPR-Cas9 screen targeting active regulatory elements, we identify the zinc-finger protein ZNF512B as a key suppressor of the SASP. ZNF512B loss induces DNA damage, activates cGAS-STING signaling, and triggers inflammatory transcriptional reprogramming. In contrast, ZNF512B promotes preferential DNA repair at regulatory genomic regions, limiting SASP induction. Mechanistically, ZNF512B is rapidly recruited to DNA-damage sites via distinct zinc-finger domains and facilitates NuRD complex targeting to damaged chromatin, enabling precise repair. In human neuromuscular organoids, ZNF512B deficiency induces inflammation, lineage imbalance, and cytokine secretion resembling amyotrophic lateral sclerosis (ALS)-associated pathology. In vivo, ZNF512B overexpression reduces DNA damage and inflammation following acute liver injury. Together, these findings support a mechanism of preferential DNA repair that contributes to maintaining genome integrity, suppressing SASP and inflammation."

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS."

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."

Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants.

However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3\u00a0Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments."

While age-standardized rates have shown decline in certain regions, the absolute number of cases is escalating due to the interplay of global aging and population growth.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis (ALS) is increasingly recognized as a fatal neurodegenerative disease with a global epidemiology characterized by complex variations across age, sex, and geography. Current research indicates that the apparent rise in ALS cases is driven by demographic change. As global populations age, the number of individuals entering the age range of peak incidence (70\u201379 years) increases, leading to a higher total disease burden despite potentially stable or declining age-standardized rates. This demographic transition is particularly evident in studies analyzing longitudinal trends. Furthermore, the role of environmental factors and genetic susceptibility in a predisposed population continues to be investigated as a secondary driver of the disease landscape.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Population aging accounted for 46.0% of the increase in DALYs in China from 1990 to 2021.\n* Age-standardized rates of motor neuron disease have declined in many settings despite rising absolute numbers.\n* The global pooled incidence of ALS is 1.65 per 100,000 person-years.\n* Incidence and prevalence of ALS are significantly lower in females than in males.\n* ALS burden is higher in high-income countries compared to middle-income countries.\n* There is a marked age-dependent pattern for ALS burden, peaking at ages 70-79.\n* Environmental exposure to toxic metals (lead, cadmium, mercury) and chemicals like formaldehyde is linked to neurodegenerative risk.\n* The gut-microbiota-brain axis and dietary factors, including vitamin intake, are increasingly implicated in ALS progression.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

These demands place substantial strain on family carers and often require input from paid homecare workers. Despite their essential role, little is known about how homecare workers contribute to complex MND care, how they integrate within multidisciplinary teams, or how families experience their involvement. To examine people living with MND and family members' perspectives of homecare worker roles, responsibilities, relationships when complex interventions are required. A qualitative secondary analysis of data from two prior studies exploring home ventilation and tracheostomy ventilation in MND. Seven relevant NVivo nodes and 33 sub-nodes from interviews with 68 participants were re-coded using a deductive framework. Fourteen new nodes and 11 sub-nodes were generated and organised into three themes: care commissioning and provision; relationships; and the home environment. Participants described fragmented and inconsistent care commissioning, requiring families to advocate persistently for adequate support. Challenges included funding barriers, high staff turnover, and limited MND-specific knowledge, which undermined trust and compromised safe, effective care. Relationships with homecare workers ranged from highly valued, stable partnerships to strained interactions shaped by competence concerns, emotional labour, and mismatched expectations. The presence of homecare workers and medical equipment transformed the home into a quasi-clinical space, reducing privacy, disrupting routines, and requiring households to adapt around care provision. Yet strong relationships with homecare workers could enhance quality of life. Homecare workers play a critical role in delivering complex home-based MND care, yet quality is inconsistent. Improving training, stabilising staffing, supporting care coordination, and preparing families for the relational and environmental impact of homecare are essential for fostering sustainable, trusted care relationships, and improving outcomes for people living with MND and their families. Paid homecare support for people with motor neurone disease: Insights from people with MND and their families This study explores how people living with motor neurone disease (MND), and their family members, experience support from paid homecare workers when complex medical interventions, such as ventilation, feeding tubes, suction and hoists are needed at home. As care needs increase, families often need help from paid homecare workers, yet no research has asked families about what this support is like. To address this, we re-analysed interview data from two earlier studies about living with home ventilation in MND, and developed three main themes: Care commissioning and provision: Participants described the process of securing a care package as confusing and often exhausting, with multiple organisations involved. Families frequently had to push to get the support they needed. Problems included shortages of trained staff, high staff turnover, and delays caused by complex funding rules. Relationships with homecare workers: Good homecare workers made a huge positive difference. Relationships with homecare workers ranged from highly positive, built on trust, skill and becoming \u2018part of the family\u2019, to strained, particularly when workers lacked MND-specific training or confidence with equipment. Trust was crucial: when present it eased pressure on families but when absent it increased stress and vigilance. Impact on the home environment: Having carers in the house, changed home life, reducing privacy, disrupting household routines, and living spaces became filled with medical equipment and ever-present homecare workers. Families described feeling like hosts in their own homes and sometimes having to manage the emotional labour of being polite or accommodating even when exhausted. Overall, the study shows that homecare workers play an essential role in complex MND care, but quality is inconsistent. Better coordination and support for families to manage these close relationships within the home are vital to reduce pressure on families and improve quality of life.\n\nID: 42402806\nTitle: Very low-amplitude muscle activity increases probability of motor evoked potentials in healthy individuals and in amyotrophic lateral sclerosis.\nAbstract: Muscle contraction increases motor evoked potential (MEP) amplitude, decreasing motor threshold (MT). Correspondingly, trials where baseline EMG amplitude exceeds a specified threshold are often rejected. We aimed to investigate the influence of motor activity below such a threshold of MEP amplitude. We retrospectively analysed TMS-EMG data collected during resting MT (RMT) measurement in 45 healthy control subjects (1794 data points) and 35 people with amyotrophic lateral sclerosis (ALS; 1229 data points). Trials with de-meaned root mean squared (RMS) EMG amplitude of >10\u00a0\u00b5V throughout the 200\u00a0ms prior to stimulation were rejected. Generalised linear mixed-effects models assessed effects of muscle activity below this rejection threshold on the probability of evoking an MEP with peak-to-peak amplitude of \u226550\u00a0\u00b5V. Greater sub-rejection-threshold activity significantly increases MEP probability in control subjects and people with ALS. Models predicted a 38%-43% increase in MEP probability when baseline RMS-EMG amplitude increased from 1 $\\hskip.001pt 1$ to 9\u00a0\u00b5V. Sub-rejection-threshold baseline activity was significantly greater in ALS than control subjects. Below a typical rejection threshold, greater baseline RMS-EMG amplitudes markedly increase the probability of evoking MEPs with peak-to-peak amplitude of \u226550\u00a0\u00b5V. Effects of sub-rejection-threshold muscle activity should be accounted for when comparing RMT measures, particularly between cohorts where such activity differs, such as ALS and control subjects.\n\nID: 42401978\nTitle: Regional wasteosome accumulation across neurodegenerative diseases points to a shared underlying mechanism potentially related to glymphatic insufficiency.\nAbstract: The glymphatic system plays a key role in clearing waste products from the brain and is essential for maintaining brain homeostasis. When dysfunctional, it appears to contribute to pathological changes that exacerbate brain disorders, including neurodegenerative diseases. Additionally, wasteosomes, also known as corpora amylacea, are structures that function as waste containers and are thought to increase in response to chronic glymphatic insufficiency. Hence, in this study, we evaluated whether the accumulation and distribution of wasteosomes are compatible with both the potential role of wasteosomes as a hallmark of the chronic glymphatic insufficiency and the presence of this insufficiency in certain neurodegenerative diseases. Accordingly, brain tissue from 185 donors was analysed, including cases of Alzheimer's disease, amyotrophic lateral sclerosis with TDP-43 proteinopathy, frontotemporal lobar degeneration with TDP-43 or tau proteinopathy, and non-diseased controls. Wasteosomes were examined across 28 brain regions comprised within 5 major brain areas, using region-specific scoring systems. Analysis was conducted through variance and covariance analyses, along with decision tree procedures. The findings reveal that wasteosomes are consistently found in specific critical regions, with a higher burden in donors with neurodegenerative diseases compared with controls. These regions are independent of the regional distribution of the underlying proteinopathy, and are potentially associated with glymphatic drainage pathways. From an integrated perspective, although further studies are required, the increased presence of wasteosomes in these critical regions across all diseased groups is consistent with the potential presence of chronic glymphatic insufficiency in these diseases.\n\nID: 42399099\nTitle: Global epidemiology of amyotrophic lateral sclerosis: a systematic review and meta-analysis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with the global epidemiological profile remaining incompletely understood. While previous systematic reviews existed, an updated comprehensive synthesis is needed to delineate the disease burden. We searched PubMed, Embase, Scopus, Web of Science and Cochrane databases from inception to 18 February 2025, for studies reporting the incidence, prevalence or mortality of ALS in the general population. Pooled estimates with 95% CIs were calculated, and subgroup analyses were performed. Of 29\u2009110 articles initially screened, 142 were included. Global pooled incidence was 1.65 per 100\u2009000 person-years (95% CI 1.43 to 1.91), prevalence was 5.05 per 100\u2009000 population (95%\u2009CI 4.26 to 5.99) and mortality was 1.26 per 100\u2009000 person-years (95%\u2009CI 0.94 to 1.69). Both incidence rate ratio (IRR=0.74) and prevalence rate ratio (PRR=0.69) indicated significantly lower disease burden in females than in males. The burden of disease exhibited a marked age-dependent pattern, peaking at ages 70-79. Temporal trend analyses revealed a consistent increase in prevalence from 1963 to 1999\u2009onwards, while incidence peaked in 2014-2017. Geographically, incidence and prevalence were highest in Europe, North America and Oceania and lowest in Asia and South America. The disease burden was significantly higher in high-income countries compared with both upper-middle-income and lower-middle-income countries. This systematic review provides updated global ALS burden estimates, showing variations by sex, age, time and geography and underscoring the complex interplay of genetic, environmental and socioeconomic factors, with implications for health planning, resource allocation and etiological research.\n\nID: 42394962\nTitle: Decremental responses following repetitive nerve stimulation in spinal and bulbar muscular atrophy.\nAbstract: The presence of decremental responses following repetitive nerve stimulation (RNS) in amyotrophic lateral sclerosis (ALS) is well established. However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3\u00a0Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42394299\nTitle: Letter to the Editor in Response to \"Age and Nocturnal Polyuria in Nocturia: A Multicenter Voiding Diary Cohort Study\".\nAbstract: Kawase et al.'s recent multicenter cohort study offers significant evidence about the relationship between nocturnal polyuria (NP) in nocturia patients and aging. The study shows that overactive bladder, maximal voided volume, and 24-h urine volume are significant predictors of NP and that both the nocturnal polyuria index and the prevalence of NP rise with age. Although these results significantly advance our knowledge of age-related urinary dysfunction, a number of methodological issues need to be addressed. The reported relationships may have been impacted by the retrospective design, reliance on self-reported voiding diaries, and lack of information on renal function, sleep problems, hydration status, and diuretic use. Furthermore, using a single diagnostic criteria for NP across all age groups might not accurately represent aging-related physiological changes. To better diagnose and treat nocturnal polyuria in older persons, future prospective studies that take these factors into account and assess age-specific diagnostic criteria are required.\n\nID: 42393482\nTitle: Diverging trends in motor neuron disease burden in China: an ageing-driven increase despite declining age-standardised rates - a GBD 2021 analysis.\nAbstract: Age-standardised rates of motor neuron disease (MND) have declined in many settings, yet the absolute burden continues to rise in ageing populations. Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations.\n\nID: 42388397\nTitle: Long-term use of rozanolixizumab in generalised myasthenia gravis: final pooled analysis of the phase III MycarinG study and two open-label extensions.\nAbstract: Myasthenia gravis (MG) is a rare autoimmune disease characterised by fluctuating and fatigable muscle weakness. In the randomised, double-blind phase III MycarinG study, one 6-week rozanolixizumab cycle significantly improved MG-specific outcomes versus placebo and was generally well tolerated in patients with generalised MG (gMG). To assess the efficacy and safety of cyclic rozanolixizumab treatment. A pooled analysis of the MycarinG, MG0004 and MG0007 studies. Following MycarinG, eligible patients could enrol in the open-label extension studies MG0004 or MG0007 to receive rozanolixizumab 7 or 10\u2009mg/kg. In MG0004, patients received chronic weekly treatment for \u2a7d52\u2009weeks. In MG0007, after an initial 6-week treatment cycle, subsequent cycles were based on symptom worsening (investigator's discretion). Final efficacy data were pooled across MycarinG, MG0004 (first 6\u2009weeks) and MG0007 for patients receiving \u2a7e2 symptom-driven cycles. Efficacy endpoints included change from baseline (CFB) in MG Activities of Daily Living (MG-ADL), MG Composite (MGC) and Quantitative MG (QMG) scores. Safety outcomes were assessed in patients who received \u2a7e1 cycle with a \u2a7d8-week follow-up period across MycarinG and MG0007. Overall, 188 patients received \u2a7e1 cycle and 129 received \u2a7e2 symptom-driven cycles. Across Cycles 1-13, mean (standard deviation) CFB to Day 43 in MG-ADL score ranged from -3.2 (3.3 (n\u2009=\u2009113; Cycle 3)) to -6.0 (3.9 (n\u2009=\u200924; Cycle 12)). Consistent improvements in MGC and QMG scores were also observed across repeated cycles. Treatment-emergent adverse events (TEAEs) were experienced by 175/188 (93.1%) patients; most mild or moderate. Incidence remained stable with repeated cyclic treatment among patients who remained in the study at each cycle. The most common TEAE was headache (n\u2009=\u200994/188 (50.0%)). Repeated rozanolixizumab treatment cycles demonstrated consistent, clinically meaningful improvements in MG-specific outcomes as early as 1\u2009week after the first infusion. Rozanolixizumab was generally well tolerated with an acceptable safety profile, supporting its long-term use as a treatment option for adults with gMG. ClinicalTrials.gov: NCT03971422; NCT04124965; NCT04650854. Long-term treatment with cycles of rozanolixizumab improved symptoms in patients with generalised myasthenia gravis in a combined analysis of final data from the MycarinG study and its two extension studies Generalised myasthenia gravis (gMG) is an autoimmune disease that damages the connections between nerves and muscles, causing muscle weakness. In the MycarinG study, treatment with rozanolixizumab once a week for 6 weeks was better at improving gMG symptoms than placebo in adults with gMG. After MycarinG, patients could enter the extension studies MG0004 and MG0007. These studies assessed the side effects of long-term rozanolixizumab treatment and measured patients\u2019 symptoms to see whether rozanolixizumab remained effective. In MG0004, patients received rozanolixizumab once a week for up to 52 weeks. In MG0007, patients received rozanolixizumab once a week for 6\u2009weeks, termed a treatment cycle. After the first treatment cycle, patients only received more cycles if their symptoms worsened. We looked at data from patients who received repeated rozanolixizumab treatment cycles across MycarinG, MG0004 (first 6 weeks only) and MG0007. Treatment side effects and gMG symptoms were assessed. Overall, 129 patients received two or more rozanolixizumab cycles due to worsening symptoms. We saw consistent improvements in gMG symptoms across multiple measures; improvements were maintained over repeated treatment cycles. Altogether, we assessed 188 patients for side effects; 175 (93.1%) reported a side effect, most of which were mild or moderate in severity. The most common side effect was headache. The number of reported side effects and how bad they were did not change much across treatment cycles among patients who stayed in the study at each cycle. In the first year of treatment, patients had an average of four treatment cycles. Based on this, rozanolixizumab treatment would be expected to follow a repeated pattern of 6\u2009weeks on treatment and 6\u20138\u2009weeks off in the first year. Together, these data suggest that repeated rozanolixizumab cycles can be used for long-term treatment in patients with gMG.\n\nID: 42387528\nTitle: Fidelity in the context of adapting a digital intervention for depression from an evidence-based in-person format in Vietnam.\nAbstract: Digital interventions have emerged as a promising way to better meet growing population mental health needs. Our team developed a digital depression intervention (VMood; smartphone app) in Vietnam. VMood is adapted from an evidence-based in-person intervention (SSM) developed in Canada and uses cognitive behaviour therapy (CBT) principles with remote coaching by non-specialist providers. Fidelity-adaptation is a major tension in implementation science. Fidelity is the degree an intervention is designed and delivered as intended. Conversely, adaptations are sometimes made for specific contexts. This paper aims to identify key elements of fidelity-adaptation - the degree VMood is consistent theoretically with the SSM intervention and practically with implementing digitally in the Vietnamese setting. This study uses Perez et al.'s modified version of Carroll et al.'s Implementation Fidelity Framework, focusing on Objective 1: Conceptualizing what intervention fidelity means in this specific context (across modes and cultures) and Objective 2: Conducting fidelity testing to identify key elements along the fidelity-adaptation continuum. Ethnographic data from team meetings explored essential components that must remain intact and necessary adaptations. Non-specialist providers and app users from Vietnam tested VMood. Experts familiar with CBT provided theoretical feedback. Interviews or focus groups were conducted with all participants to gain insights into the adaptive intervention. Qualitative data were analyzed using thematic content analysis. Participants agreed that VMood captures the essential theoretical components from SSM, noting certain elements of SSM (e.g., change in human contact to online) could not be replicated digitally. Participants also presented adaptation suggestions unique for the digital format to strengthen VMood's acceptability, including keeping the app simple by reducing the amount of text; incorporating more dynamic content (e.g., animations) to increase engagement; and including more culturally appropriate scenarios. Finally, key potential moderators to fidelity reported included quality of program delivery and participant responsiveness. Findings identified intervention specific elements of fidelity-adaptation and showed that VMood retained essential components of SSM while incorporating adaptations to support implementation within the Vietnamese context. With the global increase in digital health services adapted from in-person delivery, understanding how to balance fidelity with necessary adaptations is important both theoretically and practically.\n\nID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

A total of 2,215 thyroid surgeries and 194 autopsies were reviewed, identifying 17 and 1 case of NRLN, respectively. Data regarding nerve anatomy, associated vascular anomalies, and patient medical history were collected and analyzed. Neck ultrasound examinations were subsequently performed on the 17 living patients, 5 months to 19 years post-surgery, by three radiologists specializing in head and neck soft-tissue imaging. Two radiologists were blinded to the specific nerve anatomy, while one was unblinded. Vascular anomalies of the aortic arch were described only by the unblinded radiologist. Among the 17 NRLN cases, three (16.7%) exhibited normal vascular anatomy. According to Toniato et al.'s classification, one case each was categorized as 2a, 2b, and one case involved a coexisting right NRLN and right RLN. No definitive recurrent paresis was observed, with only one patient experiencing transient palsy lasting 5 weeks. Histological evaluation revealed no structural differences between NRLN and RLN variants, although their epineurium and adventitia were notably thinner than those of the vagal nerve. Achieving blood-free conditions for meticulous dissection and preserving sympathetic nerve branches are essential for optimal functional outcomes in thyroid surgeries involving NRLNs.\n\nID: 42379476\nTitle: Exposure to toxic metals/metalloids in the environment and in vitro fertilization outcomes in a population group from Romania.\nAbstract: Globally, the infertility prevalence (both genders) has shown a gradual upward trend, with a 0.5%-0.7% annual rise in infertility rates between 1990 and 2021. An increasing proportion of women in Romania experiencing infertility are resorting to in vitro fertilization (IVF) to achieve pregnancy. Our study included 47 women who completed an IVF cycle at the 1st Obstetrics and Gynecology Clinic (Cluj-Napoca), between April - October 2019, and July - December 2022. All participants completed a questionnaire. We collected data from the participant medical records on antral follicle count, levels of hormones, response to ovarian stimulation, number of retrieved oocytes, thickness of the endometrial mucosa, and IVF endpoints (fertilized oocytes, number and quality of embryos, pregnancy, live births). Urine, blood, ovarian follicular fluid, and endometrial flushing fluid specimens were collected at the time of oocyte retrieval, for metal and genetic analysis. Lead (Pb), arsenic (As) and cadmium (Cd) levels were measured in biological samples collected from our study participants using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) technique. In approximately 19% of the analyzed samples, the total urinary As exceeded the reference value of 15 \u00b5g/L. Also, in 15% of the samples, urinary Cd exceeded the reference value of 2 \u00b5g/L, while the blood Pb levels were below 10 \u00b5g/dl. Our study results indicated no significant differences as regards the IVF outcomes in relation with low-level As, Cd and Pb exposure, whereas higher tobacco smoke exposure, assessed via urinary cotinine, was linked to a lower fertilized oocytes and blastocysts number.\n\nID: 42378369\nTitle: RETRACTED: Kim et al. The Angiogenesis Inhibitor ALS-L1023 from Lemon-Balm Leaves Attenuates High-Fat Diet-Induced Nonalcoholic Fatty Liver Disease Through Regulating the Visceral Adipose-Tissue Function. Int. J. Mol.

Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies.\n\nID: 42367369\nTitle: Preparing Amyotrophic Lateral Sclerosis Clinics to Provide Longitudinal Care for Individuals Carrying ALS Risk Variants.\nAbstract: Emerging genetic therapies and the expansion of genetic testing are identifying individuals carrying amyotrophic lateral sclerosis (ALS) risk variants who would benefit from surveillance and early intervention. Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.\n\nID: 42365206\nTitle: Navigating the CBD: How Urban Risk Environment Shapes Daily Life for People Who Use Drugs in Edmonton's Central Business District.\nAbstract: Public drug use in urban central business districts (CBDs) presents an urgent public health challenge in Canada. People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170\u00a0h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected.\n\nID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.\n\nID: 42360421\nTitle: [Prevention instead of remediation-screening, lifestyle factors, and prostate care\u00a02.0-transition of urology to healthcare coach : Holistic approach to prostate health].\nAbstract: Establishment of an organized, risk-adapted prostate cancer screening program in Germany could serve as a\u00a0key entry point for preventive men's health. How can the introduction of an organized, risk-adapted prostate cancer screening program in Germany shape preventive urology of the future? This narrative review article is based on guidelines and expert consensus supported by a\u00a0literature search in PubMed. The cited studies represent the most relevant work on this topic and were selected to illustrate developments and fundamental concepts; however, completeness is not claimed. Serum prostate-specific antigen (PSA) levels and prostate MRI not only identify patients at increased risk for prostate cancer but also offer insights into other urological conditions, such as lower urinary tract symptoms and hypogonadism. In analogy to other early detection strategies, PSA testing at the age of 45-50\u00a0years could serve as a\u00a0simple triage test to guide risk-adapted follow-up and timely referral to urological care. Lifestyle factors-including regular physical activity, a\u00a0balanced diet, and pelvic floor training-may favorably influence urological health and related outcomes. While organized prostate cancer screening has already been shown to improve cancer-specific mortality to a\u00a0level comparable to mammography, a\u00a0more holistic approach may further enhance its overall benefit. Urology has significant opportunities to actively promote healthy behaviors among aging men. The establishment of an organized prostate cancer screening program provides an ideal entry point for this purpose. Modern screening concepts should incorporate holistic health promotion for aging men alongside direct oncological endpoints. HINTERGRUND: Die Etablierung einer organisierten, risikoadaptierten Prostatakarzinomfr\u00fcherkennung k\u00f6nnte Grundlage einer pr\u00e4ventiven M\u00e4nnergesundheit sein. Wie kann die Einf\u00fchrung einer organisierten, risikoadaptierten Prostatakarzinomfr\u00fcherkennung die pr\u00e4ventive Urologie von morgen pr\u00e4gen? Dieser narrative \u00dcbersichtsartikel auf der Grundlage von Leitlinien und Expertenkonsens wird unterst\u00fctzt durch eine Literaturrecherche auf PubMed (2000\u20132026). Die zitierten Studien stellen nach Meinung der Autoren die relevanten Arbeiten hierzu dar und wurden ausgew\u00e4hlt, um Entwicklungen und prinzipielle Konzepte zu veranschaulichen, beanspruchen jedoch keine Vollst\u00e4ndigkeit. Der PSA-Wert (prostataspezifisches Antigen) und die MRT liefern nicht nur Hinweise auf ein Prostatakarzinom, sondern auch auf andere urologische Erkrankungen wie Miktionsbeschwerden oder Testosteronmangel. Parallel zu anderen Fr\u00fcherkennungsuntersuchungen k\u00f6nnte der PSA-Wert mit 45\u201350\u00a0Jahren als einfaches Triage-Tool fungieren, um risikoadaptierte Verlaufskontrollen sowie fachurologische Vorstellungen zu steuern. Lebensstilfaktoren wie Bewegung, eine gesunde Ern\u00e4hrung und Beckenbodentraining k\u00f6nnen urologische Erkrankungen und deren Folgen positiv beeinflussen. Durch eine organisierte Prostatakarzinomfr\u00fcherkennung kann das karzinomspezifische Mortalit\u00e4t bereits heute vergleichbar zur Mammographie verbessert werden, durch ein holistischeres Herangehen kann der Gesamtnutzen jedoch noch mehr gesteigert werden. Die Urologie hat gro\u00dfe Chancen, die Gesundheitskompetenz des alternden Mannes, aber auch Fr\u00fcherkennungsma\u00dfnahmen f\u00fcr andere Erkrankungen, aktiv zu f\u00f6rdern. Die organisierte Prostatakarzinomfr\u00fcherkennung k\u00f6nnte hierf\u00fcr einen sinnvollen Einstieg darstellen. Moderne Fr\u00fcherkennungskonzepte sollten die ganzheitliche Gesundheitsf\u00f6rderung des alternden Mannes neben direkten onkologischen Endpunkten miteinbeziehen.\n\nID: 42360043\nTitle: Comparison of Proteomic Analysis of Cerebrospinal Fluid From Neurological Patients With and Without Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterised by progressive muscle weakness in both bulbar and extremity muscles, leading to a diverse clinical phenotype with motor and non-motor symptoms. Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.\n\nID: 42352907\nTitle: The Dual Role of Glial Extracellular Vesicles in Neurodegeneration: Insights from iPSC-Based Models.\nAbstract: Extracellular vesicles (EVs) have emerged as key mediators of intercellular communication in the brain, with glial cell-derived EVs increasingly recognized for their roles in maintaining brain homeostasis and contributing to the progression of neurodegenerative diseases. By transferring a diverse cargo of bioactive molecules, including proteins, RNAs, and organelles, EVs influence recipient cell behavior and overall brain function. In neurodegenerative conditions, glial EVs can either propagate pathogenic signals or deliver neuroprotective and regenerative cues, depending on their cellular origin and molecular composition. This context-dependent heterogeneity highlights the need for physiologically relevant human models to investigate EVs biology. Human induced pluripotent stem cell (iPSC)-derived glial models provide a disease-relevant platform, as they recapitulate key pathological features of Alzheimer's disease (AD), Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). When further integrated with brain organoid platforms, these iPSC-based systems enable the generation of three-dimensional environments that closely resemble in vivo EVs dynamics. Importantly, glial EVs can modulate cellular pathways involved in neuronal survival and function. Indeed, their potential to interact with and, under specific experimental conditions, traverse the blood-brain barrier (BBB) has contributed to growing interest in their application for biomarker discovery and therapeutic development. Engineered and patient-specific EVs derived from iPSCs are emerging as promising tools for targeted, cell type-specific, therapeutic approaches, although their clinical applicability still requires further validation. This review discusses the emerging evidence supporting the dual role of iPSC-derived glial EVs in health and disease, underscores the translational potential of iPSC-based platforms for mechanistic studies, and outlines their promise as precision medicine tools for diagnostics and therapy.\n\nID: 42347662\nTitle: Fasciculations Following COVID-19 Vaccination-A Case Series of Ten Patients.\nAbstract: Introduction: Vaccination against COVID-19 has been crucial in controlling the pandemic. While side effects are typically mild, rare neurological complications have been reported. This is a case series of ten patients who reported of persistent fasciculations after COVID-19 vaccination. Methods: We describe the clinical presentation and diagnostic work-up of ten patients with new-onset fasciculations in temporal proximity to COVID-19 vaccination. Patients with prior SARS-CoV-2 infection or known alternative causes of fasciculations were excluded. Routine clinical data, including neurological examination, laboratory results, and electrophysiology (electromyography and nerve conduction studies), were analyzed. Results: Ten patients (5 male, 5 female; mean age 42.4 years) reported fasciculations beginning within 6 h to 13 days post-vaccination and persisting for 2-12 months at the time of presentation. Fasciculations were accompanied by additional symptoms such as paresthesia and fatigue. Laboratory results were mostly unremarkable; two patients had positive myositis antibodies without clinical correlates. Electrophysiology was unremarkable in six patients, while fasciculation potentials were detected in four patients. Nine were diagnosed with probable benign fasciculation syndrome (BFS), and one met diagnostic criteria for amyotrophic lateral sclerosis (ALS). Discussion: In this small, retrospective case series, most cases of post-vaccination fasciculations were benign and compatible with BFS. Whether BFS onset was causally linked to vaccination or due to a nocebo effect remains unclear. One patient was diagnosed with ALS, though a causal link remains speculative given the study's limitations and rarity of similar reports. Larger, prospective studies are needed to validate these observations and explore underlying pathophysiological mechanisms.\n\nID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1\u03b2, \u03b3 interferon (IFN-\u03b3), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1\u03b2, IFN-\u03b3, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1\u03b2 and IFN-\u03b3 decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1\u03b2,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05).

During incremental workload exercise, femoral venous oxyhemoglobin (O2Hb) saturation exhibits a reproducible, momentary increase at the gas exchange threshold-coinciding with the inflection point of the in vivo O2 non-equilibrium curve (ONC). This suggests a transient shift in Hb's binding dynamics. We hypothesized that at this threshold, Hb tetramers carrying \u22641 bound O2 become predominant. In this state, the last bound O2 promotes further cooperative binding, but its release confers no cooperative advantage for unloading, biasing toward O2 rebinding. Using the O2 equilibrium curve models of Dash et al. (2016) and Adair, we computed the distribution of Hb's O2 ligation states across 12 pooled mean femoral venous blood samples from incremental workload cardiopulmonary exercise testing of five healthy male participants. At the gas exchange threshold-where the ONC inflects and flattens-tetramers with \u22641 O2 indeed dominated. This ligation-state distribution is consistent with Perrella et al.'s (1999) cryogenic resolution of native human Hb, which shows that carbon monoxide-ligated Hb tetramers peak at ~15-20% saturation, matching femoral venous ranges at the gas exchange threshold. Our results suggest that, at sufficiently low O\u2082Hb saturation, Hb may favor O\u2082 rebinding over cooperative unloading. We propose that glycolytic proton production and other Bohr effectors may counter this predicted binding bias supporting continued O\u2082 unloading. If confirmed, this mechanism unifies long-standing controversies in O2 transport physiology, framing the Hb-Bohr system as a proportional-integral controller of tissue oxygenation.\n\nID: 42338888\nTitle: Interplay between B vitamins, fiber, and Bacteroides abundance: a predictive model for anxiety and depression in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and incurable neurodegenerative disease that not only affects motor function but is also associated with gastrointestinal and emotional disturbances. Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.\n\nID: 42334507\nTitle: Associations influencing quality of life in caregivers of patients with amyotrophic lateral sclerosis: a stress-process model approach.\nAbstract: Caring for patients with amyotrophic lateral sclerosis (ALS) involves demands that reduce caregivers' quality of life. Although caregiver burden and perceived social support was conceptualized as an independent correlate of quality of life rather than a factor operating primarily through caregiver burden. This study examined these associations within a stress-process framework in which perceived social support was conceptualized as an independent correlate rather than a buffering factor. This cross-sectional analytical study included 118 informal caregivers of patients with ALS. Primary stressors were defined as patient functional status (ALSFRS-R), caregiving duration, and communication difficulty. Caregiver burden (Zarit Burden Interview) was considered a secondary stressor. Physical and mental quality of life were assessed using the SF-12, and perceived social support was measured with the Multidimensional Scale of Perceived Social Support. Hierarchical regression analyses were performed to examine associations specified in the conceptual model while controlling for caregiver sociodemographic and socioeconomic variables. Additional mediation analyses were conducted to examine whether caregiver burden mediated the relationship between perceived social support and quality of life. Poorer patient functional status was significantly associated with higher caregiver burden, whereas communication difficulty showed a positive but non-significant association after adjustment for caregiver characteristics. Caregiver burden showed negative associations with both physical and mental quality of life. Perceived social support remained positively associated with quality of life after adjustment for caregiver burden and contributed additional explained variance in the models. Mediation analyses showed no evidence that caregiver burden mediated the association between perceived social support and either physical or mental quality of life. The findings are consistent with a stress-process framework in ALS caregiving, in which caregiver burden represents a central factor statistically associated with both caregiving stressors and quality of life, while perceived social support shows an independent association with quality of life. These findings suggest that both caregiver burden and perceived psychosocial resources may be relevant to caregiver well-being, although causal and intervention-related implications require further investigation. Caring for a person with amyotrophic lateral sclerosis (ALS) is physically and emotionally demanding, and many caregivers experience reduced quality of life. Previous studies have examined caregiver burden and social support separately, but it is not well understood how these factors work together to influence caregivers\u2019 well-being. This study examines how disease-related challenges, caregiver burden, and perceived social support are connected, and how these factors jointly affect the physical and mental quality of life of ALS caregivers. The study tests a conceptual model proposing that caregiving challenges increase caregiver burden, which in turn affects quality of life, while perceived social support contributes directly to quality of life rather than simply reducing stress. Worse patient functioning and communication difficulties were linked to higher caregiver burden. Higher burden was associated with poorer physical and mental quality of life. Perceived social support remained positively related to quality of life even after accounting for caregiver burden. These findings suggest that improving social support and reducing caregiver burden are both important for maintaining quality of life among ALS caregivers.\n\nID: 42331015\nTitle: Malnutrition as a Risk Factor for Cerebral and Glaucomatous Neurodegeneration - Mechanisms and Therapeutic Strategies.\nAbstract: BACKGROUND: Neurodegenerative diseases are an increasing challenge for healthcare systems in the context of demographic change. They affect the central nervous system, including the brain-manifesting, for example, as dementia-as well as the retina, as seen in glaucoma or age-related macular degeneration. Malnutrition-defined as quantitative or qualitative under- or overnutrition-affects key mechanisms that contribute to neuronal and retinal neurodegeneration. OBJECTIVE: The aim of this study is to systematically present the pathophysiological mechanisms of malnutrition-related neurodegeneration, to evaluate the current evidence on dietary patterns and cognitive health, and to derive practical clinical strategies for nutritional optimization. METHODS: Narrative literature review based on peer-reviewed publications from the fields of nutritional medicine, geriatrics, neurology, ophthalmology, and public health. RESULTS: Malnutrition promotes oxidative stress, mitochondrial dysfunction, chronic neuroinflammation, and vascular dysregulation, and it influences neurotransmitter synthesis. These mechanisms are relevant to both cerebral and ocular neurodegenerative processes. The Mediterranean diet and the MIND diet are associated with a significantly reduced risk of cognitive impairment; for ocular diseases, interventional studies in age-related macular degeneration in particular demonstrate protective effects of antioxidant supplementation, whereas evidence for glaucoma is currently based predominantly on observational data. Screening approaches and micronutrient diagnostics enable early identification of at-risk individuals. Building on this, individualised dietary interventions and targeted supplementation of selected nutrients could be potentially preventive and stabilising therapeutic strategies. CONCLUSION: Malnutrition is a key modifiable risk factor for neurodegenerative diseases of the brain and retina. More intense integration of nutritional diagnostics and therapy into neurological, geriatric, and ophthalmological care structures appears warranted. Neurodegenerative Erkrankungen stellen angesichts des demografischen Wandels eine zunehmende Herausforderung f\u00fcr das Gesundheitswesen dar. Sie betreffen das zentrale Nervensystem, einschlie\u00dflich des Gehirns, etwa in Form von Demenz, sowie die Retina, wie beim Glaukom oder bei der altersabh\u00e4ngigen Makuladegeneration. Fehlern\u00e4hrung \u2013 verstanden als quantitative oder qualitative Unter- bzw. \u00dcberversorgung \u2013 beeinflusst zentrale Mechanismen, die zur neuronalen und retinalen Neurodegeneration beitragen. Ziel dieser Arbeit ist es, die pathophysiologischen Mechanismen fehlern\u00e4hrungsbedingter Neurodegeneration systematisch darzustellen, die aktuelle Evidenzlage zu Ern\u00e4hrungsmustern und kognitiver Gesundheit zu bewerten sowie praxisnahe klinische Strategien zur Ern\u00e4hrungsoptimierung abzuleiten. Narrative Literatur\u00fcbersicht basierend auf Publikationen mit Peer-Review-Verfahren aus den Bereichen Ern\u00e4hrungsmedizin, Geriatrie, Neurologie, Ophthalmologie und Public Health. Fehlern\u00e4hrung f\u00f6rdert oxidativen Stress, mitochondriale Dysfunktion, chronische Neuroinflammation sowie vaskul\u00e4re Dysregulation und beeinflusst die Neurotransmittersynthese. Diese Mechanismen sind sowohl f\u00fcr zerebrale als auch f\u00fcr okul\u00e4re Neurodegenerationsprozesse relevant. Mediterrane Ern\u00e4hrung und MIND-Di\u00e4t sind mit einem signifikant reduzierten Risiko kognitiver Beeintr\u00e4chtigung assoziiert; f\u00fcr okul\u00e4re Erkrankungen zeigen insbesondere Interventionsstudien bei AMD protektive Effekte antioxidativer Supplementierung, w\u00e4hrend f\u00fcr das Glaukom bislang vorwiegend beobachtende Daten vorliegen. Screening-Ans\u00e4tze und Mikron\u00e4hrstoffdiagnostik erm\u00f6glichen die fr\u00fchzeitige Identifikation von Risikopersonen. Darauf aufbauend stellen individualisierte di\u00e4tetische Ma\u00dfnahmen sowie die gezielte Supplementierung ausgew\u00e4hlter N\u00e4hrstoffe potenziell pr\u00e4ventive und stabilisierende therapeutische Strategien dar. Fehlern\u00e4hrung ist ein zentraler, modifizierbarer Risikofaktor neurodegenerativer Erkrankungen des Gehirns und der Retina. Eine st\u00e4rkere Integration ern\u00e4hrungsmedizinischer Diagnostik und Therapie in neurologischen, geriatrischen und ophthalmologischen Versorgungsstrukturen erscheint sinnvoll.\n\nID: 42330966\nTitle: [Hereditary dehydrated stomatocytosis (= hereditary xerocytosis) - Interesting hummingbird or clinically relevant diagnosis?].\nAbstract: Hereditary stomatocytosis comprises a group of disorders of the erythrocyte membrane that lead to impaired membrane permeability for Na+ and K+ ions. The most common form, dehydrated stomatocytosis, has long been underestimated in terms of its incidence and significance. It is associated with hemolysis, usually anemia of varying severity, and a combination of primary and secondary resorptive hemochromatosis. In the perinatal period, some patients develop edema and effusions of varying severity, which usually regress spontaneously but can progress to life-threatening hydrops fetalis. Splenectomy is not only ineffective in this disease but also contraindicated due to the associated risk of thrombosis.\n\nID: 42322392\nTitle: ECAS-Based Neuropsychological Phenotyping in Amyotrophic Lateral Sclerosis: A Retrospective Study Comparing Different Algorithms.\nAbstract: This study aimed to compare different algorithms based on the Edinburgh Cognitive and Behavioural ALS Screen (ECAS) to classify patients with amyotrophic lateral sclerosis (ALS) according to their neuropsychological phenotype to identify possible discrepancies among these systems. ECAS-Cognitive and -Carer Interview (ECAS-C/-CI) scores of N\u2009=\u2009901 patients with ALS without a formal diagnosis of dementia were retrospectively retrieved. Patients were classified, pursuant to Strong et al.'s criteria, as cognitively and behaviourally normal (ALScbn), cognitively and/or behaviourally impaired (ALSci/bi/cbi), or Possible ALS-FTD, according the following ECAS-based algorithms: (1) Abrahams', solely addressing ECAS-C total and ALS-Specific subtotals; (2) Poletti et al.'s, addressing single task-level ECAS-C scores; (3) \"Subscale\", addressing ECAS-C subscales (i.e., Language, Executive, Fluency, Memory and Visuospatial). All algorithms relied on single-item-level ECAS-CI scores for behavioural classifications. Whilst agreement rates among these classifications were moderate to high (84-86%; Cohen's k\u2009=\u20090.78-0.81), and some discrepancies emerged: (1) \"ALScbn-to-ALSci\" and \"ALSci-to-ALScbn\" re-classifications occurred across the three comparisons, ranging from\u2009~\u200911% to\u2009~\u200924%; (2) the most classificatory disagreements (~\u200943%) occurred for the ALScbi category when comparing single task-level (Poletti) to total-level (Abrahams) algorithms, with patients being re-classified as either ALSbi or Possible ALS-FTD; (3)\u2009~\u200924% of Abraham's Possible ALS-FTD cases were re-classified as either ALScbi or ALSbi by the Subscale approach. Different ECAS-based algorithms for deriving Strong's phenotypes might yield slight discrepancies that could under- or overestimate a given classification.\n\nID: 42315356\nTitle: Strategic Amyotrophic Lateral Sclerosis Australia-Systems Genomics Consortium (SALSA-SGC): cohort profile.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative motor neuron disease (MND) with heterogeneity in disease onset, progression and treatment response. The Strategic ALS Australia-Systems Genomics Consortium (SALSA-SGC) was established in recognition of the need for large data sets of clinical data matched with biological samples to enable and foster ALS research and better understanding of aetiology and biological mechanisms. SALSA-SGC brought together the major Australian MND clinics to set up sustainable infrastructure that could facilitate long-term human ALS research and clinical trials nationally and internationally. Between April 2016 and December 2024, SALSA-SGC recruited 1813 participants, including 1386 ALS/MND cases, 388 controls and 39 others (asymptomatic relatives and ALS mimics). Clinical data and biospecimens are available for 1333 and 1189 ALS cases, respectively, with longitudinal data spanning 4442 total clinic visits and 3201 samples. An open-access online data explorer showcases collected datasets. Detailed clinical and questionnaire data allow an in-depth description of the cohort, informing clinical and health policy research. Screening for known ALS large-effect risk variants identified 125 mutation carriers (11.5% from N=1059), including 70 with C9orf72 expansions. Single Nucleotide Polymorphism (SNP)-array data (N=1088 cases; N=244 controls) have supported multiple published studies. SALSA-SGC resources are actively used by national and international researchers. Ongoing efforts aim to expand recruitment into regional Australia and enhance sample processing for cell-based studies. The SALSA-SGC resource is accessible by researchers under agreements governed by participant consent, human ethics committee guidelines and agreed use of data and samples.\n\nID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.\n\nID: 42404161\nTitle: Perspective and quality of life in amyotrophic lateral sclerosis patients undergoing percutaneous endoscopic gastrostomy.\nAbstract: Percutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS). While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p\u202f>\u202f0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p\u202f>\u202f0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD\u202f=\u202f6.6) to discharge (30.97, SD\u202f=\u202f5.84) and were maintained at 1-month follow-up (30.21, SD\u202f=\u202f6.7; p\u202f=\u202f0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline\u202f=\u202f33.3; 1-month follow-up\u202f=\u202f28.61; p\u202f=\u202f0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline\u202f=\u202f9.63; 1-month follow-up\u202f=\u202f7.38; p\u202f=\u202f0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42397425\nTitle: [Real-world experience with aflibercept 8\u202fmg for treatment of neovascular age-related macular degeneration after 12\u00a0months].\nAbstract: The phase\u00a03 clinical trial PULSAR demonstrated extended treatment intervals with aflibercept 8\u202fmg in treatment-na\u00efve eyes with neovascular age-related macular degeneration (nAMD) in a\u00a0large proportion of the cohort, with good drug safety. Early clinical experience in real-world settings confirmed the efficacy in both treatment-na\u00efve and pretreated patients but no data on longer observation periods are available yet. The aim of the study was to investigate the efficacy, treatment frequency and tolerability of aflibercept 8\u202fmg over a\u00a0period of 12\u00a0months in a\u00a0group of pretreated nAMD patients. A\u00a0retrospective study of 73\u00a0eyes with nAMD and pretreatment with anti-VEGF switched to aflibercept 8\u202fmg. Eyes were initially uploaded with 3\u00a0monthly intravitreal injections (IVI), followed by a\u00a0pro re nata (PRN) regimen. Outcome parameters included visual acuity development and central retinal thickness (CSRT) after upload and 12\u00a0months, treatment frequency in the year before and after switching to aflibercept 8\u202fmg, and the overall tolerability of the drug. Of the initial 73\u00a0eyes, 27\u00a0eyes (37.0%) were still receiving aflibercept 8\u202fmg after 12\u00a0months. In these eyes CSRT was reduced from 387.9\u202f\u00b1\u2009138.4\u202f\u00b5m initially to 305.5\u202f\u00b1\u200993.2\u202f\u00b5m after upload and 328.9\u202f\u00b1\u2009105.6\u202f\u00b5m after 12\u00a0months (p\u202f<\u20090.001). Visual acuity remained stable (p\u202f>\u20090.05). Compared to the year prior to switching, the injection frequency was reduced from 8.2\u202f\u00b1\u20092.1 to 6.9\u202f\u00b1\u20091.0 IVIs (p\u202f<\u20090.005). During the observation period, a\u00a0total of 5\u00a0eyes (6.8%) developed noninfectious intraocular inflammation (IOI), with all cases completely regressing with topical treatment. These results confirm a\u00a0good efficacy of aflibercept 8\u202fmg for the treatment of nAMD with reduced injection frequency after 12\u00a0months of treatment in a\u00a0portion of pretreated eyes that were often previously refractory to treatment. Longer observation intervals and experience with other treatment regimens are necessary to confirm this observation. HINTERGRUND: Die klinische Phase-3-Studie PULSAR zeigte, dass bei therapienaiven Patienten mit neovaskul\u00e4rer altersbedingter Makuladegeneration (nAMD) eine Behandlung mit Aflibercept 8\u202fmg in einem Gro\u00dfteil der Kohorte verl\u00e4ngerte Injektionsintervalle bei guter Vertr\u00e4glichkeit des Medikaments erm\u00f6glicht. Erste klinische Erfahrungen im Real-World-Setting konnten die Wirksamkeit sowohl bei therapienaiven als auch vorbehandelten Patienten best\u00e4tigen, allerdings liegen noch keine Daten zu l\u00e4ngeren Beobachtungszeitr\u00e4umen vor. Ziel der Studie war die Untersuchung der Therapiewirksamkeit, Injektionsfrequenz sowie Vertr\u00e4glichkeit von Aflibercept 8\u202fmg in einem Zeitraum von 12\u00a0Monaten bei einem Kollektiv vorbehandelter nAMD-Patienten. Retrospektive Analyse von 73\u00a0Augen mit nAMD und vorausgegangener Anti-VEGF-Therapie, die auf Aflibercept 8\u202fmg umgestellt wurden und nach einem Upload aus 3 monatlichen intravitrealen Injektionen (IVOMs) im Pro-re-nata(PRN)-Schema weiterbehandelt wurden. Untersucht wurden die Visusentwicklung und die zentrale Netzhautdicke (CSRT) nach Upload und nach 12\u00a0Monaten, die Injektionsh\u00e4ufigkeit im Jahr vor sowie nach Umstellung auf Aflibercept 8\u202fmg sowie die Vertr\u00e4glichkeit des Medikaments. Von initial 73\u00a0Augen wurden nach 12\u00a0Monaten noch 27\u00a0Augen (37,0\u202f%) mit Aflibercept 8\u202fmg behandelt. Bei diesen Augen reduzierte sich die CSRT von initial 387,9\u202f\u00b1\u2009138,4\u202f\u00b5m auf 305,5\u202f\u00b1\u200993,2\u202f\u00b5m nach Upload sowie auf 328,9\u202f\u00b1\u2009105,6\u202f\u00b5m nach 12\u00a0Monaten (p\u202f<\u20090,001). Der Visus blieb stabil (p\u202f>\u20090,05). Die Injektionsfrequenz sank im Vergleich zum Vorjahr von 8,2\u202f\u00b1\u20092,1 auf 6,9\u202f\u00b1\u20091,0 IVOMs (p\u202f<\u20090,005). Im Beobachtungszeitraum entwickelten insgesamt 5\u00a0Augen (6,8\u202f%) eine nichtinfekti\u00f6se intraokul\u00e4re Inflammation (IOI), die in allen F\u00e4llen durch topische Therapie vollst\u00e4ndig regredient war. Die Ergebnisse best\u00e4tigen bei einem Teil der vorbehandelten, oft zuvor therapierefrakt\u00e4ren Augen mit nAMD eine gute Wirksamkeit von Aflibercept 8\u202fmg bei gleichzeitiger Reduktion der Injektionsfrequenz \u00fcber 12\u00a0Monate. L\u00e4ngere Beobachtungszeitr\u00e4ume und Erfahrungen mit anderen Therapieschemata sind notwendig, um diese Beobachtung zu bekr\u00e4ftigen.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42393765\nTitle: Phenotype-specific muscle proteomic profiling in titinopathies.\nAbstract: Titinopathies are complex neuromuscular disorders with multiple phenotypes. The gene's size, comprising 364 exons, as well as the protein's size of 3.8 MDa and its extensive network of protein interactors, are key factors underlying this complexity. Various phenotypes characterize titinopathies, and this study focuses on two of them: arthrogryposis and myofibrillar myopathies. The protein deregulations associated with these two phenotypes remain unknown or have been minimally explored; however, understanding these consequences is essential for better characterizing the pathophysiological aspects of these titinopathies.The objective was to analyze protein deregulations in two cohorts of French patients with titinopathies exhibiting the arthrogryposis and myofibrillar myopathy phenotypes, and to compare them with control individuals. Protein extracts were obtained from muscle biopsies of patients, and changes in protein levels within these two groups were analyzed by mass spectrometry. The results indicate specific deregulations in each group. The networks analyzed revealed deregulation of proteins involved in fibrosis mechanisms or in the actomyosin complex for the arthrogryposis phenotype. Regulation of the muscle contraction system through deregulation of proteins involved in the cytoskeleton is impacted in patients with myofibrillar myopathy. The proteins that are quantitatively abnormal in these two groups also provide insights into the major signaling networks disrupted in titinopathies. These findings will contribute to a more precise characterization of titinopathies, enabling the identification of phenotype-specific biomarkers and potentially guiding the search for targeted therapies for these neuromuscular disorders.\n\nID: 42383392\nTitle: Role of Toll-like receptors and oral-gut-brain axis in neurodegenerative and neuropsychiatric disorders.\nAbstract: The oral-gut-brain axis is a path connecting the gastrointestinal tract and the central nervous system (CNS). The gut microbiota influences the immune system, metabolism, and nerve cells through the production of neurotransmitters and microbial metabolites that can cross the blood-brain barrier (BBB). The interplay between neuroinflammation and altered oral and gut microbiota is a bidirectional complex path modulated by inflammatory mediators. Recent studies suggest a potential role for Toll-like receptor (TLR) signaling pathways in the induction of neuroinflammation via the oral-gut-brain axis. As neuroinflammation is one of the key elements in the pathophysiology of neurodegenerative and neuropsychiatric disorders, this review was conducted to reflect on the pathophysiological pathways and clinical evidence on the role of TLR and inflammasome signaling pathways via oral-gut-brain axis in neurodegenerative diseases such as cognitive impairment, Alzheimer's disease, Multiple sclerosis, Parkinson's disease, Huntington's disease, and Amyotrophic lateral sclerosis, and psychiatric disorders such as major depressive disorder, anxiety disorders, schizophrenia, bipolar disorders, and Autism spectrum disorders. Because the contributing factors have not been fully understood yet, further studies could help provide novel therapeutic opportunities.\n\nID: 42374626\nTitle: Microbiome and metabolites impact enteric and central nervous systems in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) has been linked to gastrointestinal symptoms and alterations in the gut microbiota. The enteric nervous system (ENS) coordinates intestinal function and sits at the host-microbe interface. The mechanisms by which luminal changes relay to the central nervous system (CNS), where motor neurons reside, have yet to be completely defined. In this narrative review, we first present evidence from ALS patient cohorts and preclinical models alongside mechanistic studies of infection, dysbiosis, and related neurodegenerative diseases to discuss how the microbiota and its metabolites may affect the ENS and CNS in ALS. Next, we propose a plausible mechanism of ALS pathogenesis through the gut-microbiome-brain axis. We further offer a summary of clinical trials that have studied the impacts of the microbiota on human ALS. Finally, we discuss future directions for studies of microbiota-ENS-CNS interactions in ALS. Better understanding of the dynamic interactions among the microbiota, microbial metabolites, neuroactive metabolites, and inflammation through the ENS/CNS in ALS will provide innovative insights into ALS prevention and treatment.\n\nID: 42371122\nTitle: Quantification of amyotrophic lateral sclerosis (ALS) disease accumulation with T1-weighted high-resolution magnetic resonance imaging: validation in an independent cohort.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a progressive neuromuscular disease with multifaceted phenotypic presentation thus obstructing objective disease staging. The D50 disease progression model is a framework to comprehensively dissect biomarker-signals towards their relevance regarding disease accumulation/phase (rD50), or disease aggressiveness (D50). Based on previous findings using 1.5-Tesla Magnetic-Resonance-Imaging (MRI), this study hypothesized that high-resolution MRI markers of Grey-Matter (GM) structural integrity would enable quantification of disease accumulation, independent of aggressiveness. A separate cohort of 75 patients with ALS and 73 Healthy Controls (HC) underwent T1-weighted 3-Tesla MRI. Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p\u2009<\u20090.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p\u2009<\u20090.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p\u2009<\u20090.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results. These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness. This principle was validated across different scanners and field strengths, supporting its application for objective and non-invasive staging of patients with ALS, whereby true longitudinal studies are necessary.\n\nID: 42371053\nTitle: Neurodegenerative diseases and environmental risk factors: an overview of the available scientific evidence.\nAbstract: Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) are among the most well-known and prevalent neurodegenerative disorders. These diseases result from an interaction between the environment and genetically predisposed individuals. This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf.\n\nID: 42360551\nTitle: Targeting mtDNA to Modulate Mitochondrial Dysfunction in Neurodegenerative Diseases.\nAbstract: Mitochondrial dysfunction is a common pathological feature of neurodegenerative diseases namely Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. Although these disorders are primarily driven by disease-specific genetic and proteopathic mechanisms, increasing evidence suggests that secondary mitochondrial DNA (mtDNA) damage and heteroplasmy shifts may exacerbate bioenergetic failure and neuronal vulnerability. Distinguishing primary disease mechanisms from downstream mtDNA alterations is critical to accurately evaluate emerging therapeutic strategies. Recent advances in mtDNA-targeted genome editing have enabled the direct manipulation of mitochondrial genomes. Mitochondrially targeted zinc finger nucleases and TALENs can selectively alter mutant mtDNA to induce heteroplasmy shifts, whereas DddA-derived cytosine base editors allow precise base editing without double-strand breaks. However, each platform has distinct limitations related to the target scope, off-target risk, design complexity, and delivery efficiency. The application of CRISPR/Cas-based systems to mammalian mtDNA remains constrained by the unresolved challenges in guiding RNA import. This review critically examines mitochondrial dysfunction and mutant\u00a0mtDNA accumulation in neurodegenerative diseases. It also evaluates current and emerging mtDNA-editing techniques, and highlights key translational barriers. We highlighted that mtDNA-targeted interventions can be a promising approach for\u00a0disease-modifying or adjunctive strategies, rather than curative approaches.\n\nID: 42359947\nTitle: Noninvasive assessment of cardiovascular autonomic reflexes in amyotrophic lateral sclerosis: a systematic review.\nAbstract: Dysautonomia is gradually recognized in amyotrophic lateral sclerosis (ALS), raising concerns of secondary complications from heightened autonomic burden. Autonomic disturbances, particularly cardiac dysautonomia, significantly impact patient outcomes, contributing to increased cardiovascular risks and mortality rate. While the ALS Functional Rating Score-Revised (ALSFRS-R) measures functional decline as disease progress, it overlooks autonomic criteria - a critical factor in ALS progression. This review aims to analyze noninvasive applications of cardiovascular signal variability for continuous real-time monitoring of autonomic dysfunction in ALS, while addressing gaps in current clinical assessments. A total of 584 literatures were gathered from four databases (WoS, PubMed, Science Direct and MEDLINE EBSCOhost) - published from inception till December 2023. 21 peer-reviewed studies were included in this review after screening and meeting the inclusion criteria. Various cardiovascular signal variability metrics and autonomic protocols were discussed. Key findings highlight cardiac autonomic dysfunction in ALS is marked by reduced heart rate variability, absent blood pressure regulation upon orthostatic stress and circadian changes, prolonged QTc interval and low baroreflex sensitivity. Moreover, increased autonomic burden is associated with a shift from sympathetic to parasympathetic dysregulation as the disease progresses. Evidence highlights the need to integrate noninvasive autonomic biomarkers into digital ALS monitoring frameworks, enabling earlier detection of autonomic involvement and more precise longitudinal monitoring beyond motor decline.\n\nID: 42359357\nTitle: Innate immune crosstalk in ALS/FTD pathogenesis.\nAbstract: Marked by protein aggregation, impaired proteostasis, organelle stress, and chronic neuroinflammation, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) form a clinically, genetically, and pathologically overlapping disease spectrum. Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.\n\nID: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\n\nID: 42345500\nTitle: Formaldehyde neurotoxicity: Effects on the mammalian brain, cognitive function, and neurodegenerative risk. A scoping review.\nAbstract: Aqueous formaldehyde (FA) solution, known as formalin, is currently the primary agent used for preserving tissue samples and anatomical specimens. Formaldehyde is widely used in laboratories and the chemical industry; it also occurs as an air pollutant and endogenous cellular metabolite. The potential carcinogenic effects of formalin on the respiratory tract are well documented. A less recognized consequence of occupational exposure to FA is its detrimental effect on the central nervous system (CNS) and brain function. A literature review was conducted to investigate the effects of FA on the brain. Five databases were searched: PubMed, Web of Science (WoS), Embase, ScienceDirect, and Google Scholar. To describe the effects of FA exposure and endogenous FA generation, 35 relevant publications were collected and analyzed. The literature review demonstrated that inhalation is the most common route of FA exposure. Several studies have shown that FA may cause hippocampal damage, disrupt melatonin secretion, and induce a wide range of cognitive disorders with varying characteristics and severity. These disorders include memory impairment, disturbances in balance and spatial orientation, learning difficulties, sleep disturbances, impaired judgment, and prolonged reaction times to stimuli. Increased endogenous FA concentration has also been associated with a higher risk of neurodegenerative diseases, such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis. The literature analysis demonstrated the high neurotoxicity of FA, which may lead to numerous neuropsychiatric disorders. We aim to draw attention to the risks associated with the routine use of formalin, particularly among anatomists and pathologists, and to encourage consideration of less harmful alternative preservation agents.\n\nID: 42343420\nTitle: Immune checkpoint LAG-3 governs stage-dependent and disease-associated microglial modules in ALS model mice.\nAbstract: Immune checkpoint molecules, inhibitory receptors originally characterized in T cell biology, have recently emerged as regulators of microglial function in neurodegeneration, yet their roles in amyotrophic lateral sclerosis (ALS) remain unexplored. Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.\n\nID: 42333772\nTitle: Thymol Attenuates Klebsiella pneumoniae Induced Lung Injury via Modulation of Peroxidase-Driven Oxidative Stress and Host-Pathogen Interactions: In Vivo and In Silico Insights.\nAbstract: Klebsiella pneumoniae pneumonia drives excessive inflammatory and oxidative responses that culminate in acute lung injury (ALI) and impaired bacterial clearance. Effective therapies capable of restoring host-pathogen balance remain limited, particularly in the context of multidrug-resistant strains. This study investigated the therapeutic efficacy of thymol in a murine model of K. pneumoniae-induced ALI. Oral thymol (5-20\u2009mg/kg) markedly reduced lung injury, suppressed leukocyte infiltration, improved pulmonary histoarchitecture, and significantly enhanced bacterial clearance. Thymol reshaped systemic and local immune responses by decreasing tumor necrosis factor-\u03b1 (TNF-\u03b1) and C-reactive protein (CRP), increasing interleukin-10 (IL-10), and limiting macrophage and granulocyte recruitment. Mechanistically, thymol attenuated heme peroxidase-driven oxidative stress, as evidenced by reduced myeloperoxidase (MPO) and eosinophil peroxidase (EPO) activities, decreased malondialdehyde (MDA), hydrogen peroxide (H2O2), and nitric oxide (NO), along with restoration of catalase activity and glutathione levels. Complementary in silico docking predicted stable interactions of thymol with MPO and EPO, as well as essential bacterial metabolic enzymes, including deoxy-D-xylulose-5-phosphate synthase (DXS), acetolactate synthase (ALS), and dihydrodipicolinate synthase (DHDPS). Collectively, these findings suggest that thymol may act as a multi-target bioactive compound capable of modulating host inflammatory and redox pathways while potentially impairing bacterial metabolic fitness, thereby mitigating pneumonia-associated ALI.\n\nID: 42332177\nTitle: Trace Elements Dyshomeostasis and Toxic Metals Neurotoxicity in Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, are defined by the progressive loss of neurons through interconnected pathological mechanisms, including oxidative stress, mitochondrial dysfunction, protein aggregation, and neuroinflammation. Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases.\n\nID: 42324866\nTitle: Muscle Ultrasound Is a Sensitive Outcome Measure in ALS.\nAbstract: Muscle ultrasound is a potential outcome measure in amyotrophic lateral sclerosis (ALS), although prospective, multicenter longitudinal studies are lacking. This study aimed to evaluate muscle ultrasound as an outcome in ALS and compare its sensitivity with clinical and neurophysiological metrics. In this prospective two-center cohort study, adults with ALS underwent baseline and follow-up assessments at least 3 months apart. Clinical measures included the ALS Functional Rating Scale-Revised (ALSFRS-R) and Medical Research Council sum scores. Median nerve abductor pollicis brevis and ulnar nerve first dorsal interosseous compound motor action potential (CMAP) amplitudes were recorded. Muscle ultrasound of 11 bulbar and limb muscles was performed using harmonized protocols, with offline analysis of muscle thickness and echogenicity. Longitudinal change and effect sizes were calculated. Twenty-two patients were included (median age 59.3\u2009years, follow-up 9.6\u2009months, disease duration 23.1\u2009months). ALSFRS-R declined by -3.0 points (-0.7% per month; effect size 0.84). Median nerve CMAP amplitude decreased by -1.6\u2009mV (-1.2% per month; effect size 0.77). Muscle echogenicity increased by 0.8\u2009units (+6.0% per month), yielding the largest effect size (1.09), with increases across multiple muscles. Responsiveness improved with onset-specific muscle selection, with biceps brachii (effect size 1.12) and gastrocnemius (1.18) showing the strongest changes. Muscle thickness and fasciculation frequency did not change. Muscle ultrasound echogenicity is a sensitive structural biomarker of ALS progression, demonstrating greater responsiveness than ALSFRS-R and CMAP over 3-12\u2009months. Its accessibility and sensitivity support its utility as an outcome measure in clinical trials.\n\nID: 42317872\nTitle: Nutrients and bioactive compounds as modifiers of neurodegenerative trajectories: molecular mechanisms, translational barriers, and precision nutrition.\nAbstract: The Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS) are a growing health burden across the world with minimal disease-modifying treatment and therapy. It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions. Moreover, conceptualizing neurodegeneration as a nutrient-sensitive, systems level disorder, propose a mechanistically informed and integrative approach that combine targeted nutritional strategies with pharmacological and lifestyle therapies to more effectively modify neurodegenerative trajectories.\n\nID: 42313222\nTitle: Exercise-Driven NRF2 Activation as a Systemic Neuroprotective Strategy: Integrating Redox Biology, Muscle-Brain Crosstalk, and Therapeutic Targeting in Neurodegeneration.\nAbstract: Neurodegenerative diseases, including Alzheimer's, Parkinson's, and Huntington's diseases, are characterized by progressive neuronal dysfunction and loss. Recent evidence highlights the importance of the nuclear factor erythroid 2-related factor 2 (NRF2) pathway, a key regulator of cellular defense mechanisms, in maintaining neuronal health and function. A narrative literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar to identify relevant experimental, clinical, and review studies on NRF2 signaling, physical exercise, oxidative stress, muscle-brain crosstalk, and neurodegenerative diseases. Keywords included \"NRF2\", \"Nrf2/Keap1/ARE\", \"physical exercise\", \"exercise-induced oxidative stress\", \"myokines\", \"exerkines\", \"Alzheimer's disease\", \"Parkinson's disease\", \"Huntington's disease\", and \"amyotrophic lateral sclerosis\". NRF2 modulates the expression of a variety of antioxidant and cytoprotective genes, contributing to the protection of neurons against oxidative stress, inflammation, and protein aggregation, processes central to the pathogenesis of neurodegenerative diseases. Additionally, physical activity has been identified as a powerful modulator of NRF2 activation, with exercise offering neuroprotective effects through the induction of NRF2-mediated pathways. This review explores the interplay between NRF2 activation and physical exercise in the context of neurodegenerative diseases, detailing the molecular mechanisms by which exercise influences NRF2 activity to combat cellular damage and enhance neuroprotection. We discuss the therapeutic potential of combining exercise regimens with NRF2-targeted therapies, highlighting the promise of this dual approach in slowing disease progression, improving cognitive function, and enhancing quality of life in affected individuals. Furthermore, we examine the challenges and future directions for clinical implementation, including optimal exercise protocols and the development of NRF2-based pharmacological interventions. This review underscores the importance of NRF2 as a central mediator of neuroprotection and the therapeutic promise of physical activity in the management of neurodegenerative diseases.\n\nID: 42310292\nTitle: Impact of BECLIN1 haploinsufficiency on goblet cell function and susceptibility to colitis.\nAbstract: BECLIN1 is a central regulator of autophagy and endocytic trafficking essential for epithelial homoeostasis. While complete intestinal epithelial loss of BECLIN1 causes fatal enteritis originating in the small intestine, the consequences of its partial loss in the gut remain unclear. Given that BECLIN1 expression can vary in human disease, we investigated whether reduced BECLIN1 is sufficient to impair gut barrier function. Heterozygous Becn1 deletion (Becn1IEC+/-) in the mouse intestinal epithelium caused subtle but significant defects. These included shortened small intestines and altered epithelial architecture, despite preservation of basal autophagy, implicating trafficking-related functions. Supporting this conclusion, Becn1IEC+/- small intestinal epithelial cells showed modest increases in RAB5+ve vesicles, redistribution of E-CADHERIN and F-actin along lateral membranes and altered apico-basal cell morphology. Given the absence of overt small intestinal epithelial disruption or inflammation, as seen with complete loss of BECLIN1, we next addressed whether BECLIN1 insufficiency manifests a phenotype under stress or in other gut regions. Indeed, in the colon, Becn1IEC+/- mice exhibited reduced colonic crypt length, baseline goblet cell loss and reduced mucin production, particularly in mature goblet cells, indicating vulnerability of the mucus barrier. When challenged with dextran sulfate sodium (DSS), Becn1IEC+/- mice exhibited greater weight loss, higher disease activity, more severe histological colitis, and disproportionate loss of neutral mucins, with inflammation confined to the mucosa. Together, these findings show that BECLIN1 insufficiency does not trigger spontaneous inflammation but destabilises epithelial organisation and barrier defence, thereby sensitising the gut to inflammatory challenge and further positioning BECLIN1 as a threshold-dependent determinant of intestinal resilience.\n\nID: 42307135\nTitle: Brain activity in an end-stage ALS patient suggests the presence of an unresponsive wakefulness syndrome.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor neurons. It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40\u2009Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3\u2009Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS.\n\nID: 42304926\nTitle: Linking Neurodegeneration and Age-related Macular Degeneration: Unified Pathways and Intervention Strategies.\nAbstract: Age-related macular degeneration (AMD) is caused by the degeneration of photoreceptors and retinal pigment epithelium (RPE) along with drusen deposition and is the leading cause of vision loss in older adults. Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n\nID: 42302791\nTitle: ZNF512B safeguards genome integrity at regulatory regions to repress the SASP and inflammation.\nAbstract: Cellular senescence drives aging and disease largely through the senescence-associated secretory phenotype (SASP), yet its regulatory mechanisms remain unclear. Using a SASP reporter combined with a CRISPR-Cas9 screen targeting active regulatory elements, we identify the zinc-finger protein ZNF512B as a key suppressor of the SASP. ZNF512B loss induces DNA damage, activates cGAS-STING signaling, and triggers inflammatory transcriptional reprogramming. In contrast, ZNF512B promotes preferential DNA repair at regulatory genomic regions, limiting SASP induction. Mechanistically, ZNF512B is rapidly recruited to DNA-damage sites via distinct zinc-finger domains and facilitates NuRD complex targeting to damaged chromatin, enabling precise repair. In human neuromuscular organoids, ZNF512B deficiency induces inflammation, lineage imbalance, and cytokine secretion resembling amyotrophic lateral sclerosis (ALS)-associated pathology. In vivo, ZNF512B overexpression reduces DNA damage and inflammation following acute liver injury. Together, these findings support a mechanism of preferential DNA repair that contributes to maintaining genome integrity, suppressing SASP and inflammation.\n\nID: 42299014\nTitle: Pathogenic Proteins Driving ALS Pathogenesis: Molecular Mechanisms and Translational Therapeutic Perspectives.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of motor neurons, with protein aggregation as a central pathological hallmark. Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.\n\nID: 42298083\nTitle: The lung-brain axis in neurodegeneration: inflammatory, immune, and vascular mechanisms with therapeutic implications.\nAbstract: Neurodegenerative and chronic pulmonary diseases represent major global health challenges and have widely been investigated separately. Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.\n\nID: 42297981\nTitle: Plasma proteomic signatures of cellular aging predict human disease.\nAbstract: Aging is asynchronous across cells and organs. Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.\n\nID: 42285406\nTitle: Recent advances in neurodegenerative diseases therapeutics: The inhibition of monoacylglycerol lipase strategy.\nAbstract: Neurodegenerative diseases share common pathophysiological mechanisms, including chronic neuroinflammation, glutamatergic excitotoxicity, oxidative stress, mitochondrial dysfunction, and disruptions in synaptic and lipid homeostasis. In this context, the endocannabinoid system has emerged as a key modulator of neuroimmune communication and neuronal survival. Within this system, Monoacylglycerol Lipase (MAGL) plays a central role by regulating the levels of the endocannabinoid 2-Arachidonoylglycerol (2-AG) while simultaneously contributing to the generation of arachidonic acid and pro-inflammatory eicosanoids. Pharmacological or genetic inhibition of MAGL increases 2-AG levels and concurrently reduces the biosynthesis of pro-inflammatory lipid mediators, thereby modulating microglial activation, astrocytic responses, and neuronal excitotoxicity. Preclinical studies in models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis consistently demonstrate that MAGL blockade attenuates neuroinflammation, preserves synaptic and neuronal integrity, improves motor and cognitive function, and, in some cases, delays disease progression. Although clinical evidence remains limited, the available data position MAGL as a metabolic convergence point between inflammation and neurodegeneration, suggesting that its modulation may represent a therapeutic strategy with disease-modifying potential.\n\nID: 42283849\nTitle: [Psoriatic arthritis].\nAbstract: Psoriatic arthritis (PsA) is not an isolated joint disease, but rather an expression of a\u00a0systemic inflammatory disorder that affects multiple domains along the psoriatic disease continuum. New findings on the pathophysiology of the interleukin (IL)-23/IL-17 axis and the role of enthesitis, as well as the identification of subclinical transition phases between psoriasis and manifest arthritis, are fundamentally changing our understanding of psoriatic disease. The concepts of 'therapeutic windows' and 'interception' suggest that early targeted interventions could have a\u00a0lasting positive effect on the progression of the disease. At the same time, clinical reality requires a\u00a0differentiated therapy strategy that considers comorbidities and is oriented towards the individual patient. With a\u00a0wide range of targeted therapies and an improved understanding of the disease's pathophysiology, personalized treatment strategies are becoming the focus of therapy management. Die Psoriasisarthritis (PsA) ist keine isolierte Gelenkerkrankung, sondern Ausdruck einer systemischen, dom\u00e4nen\u00fcbergreifenden Systemerkrankung entlang eines psoriatischen Krankheitskontinuums. Neue pathophysiologische Erkenntnisse zur Interleukin(IL)-23/IL-17-Achse, zur Rolle der Enthesitis sowie zu subklinischen \u00dcbergangsphasen zwischen Psoriasis und manifester Arthritis ver\u00e4ndern das Verst\u00e4ndnis der psoriatischen Erkrankung grundlegend. Konzepte, wie \u201etherapeutische Fenster\u201c und \u201eInterzeption\u201c, legen nahe, dass fr\u00fche, zielgerichtete Interventionen den Krankheitsverlauf nachhaltig positiv beeinflussen k\u00f6nnten. Gleichzeitig erfordert die klinische Realit\u00e4t eine differenzierte, dom\u00e4nen- und komorbidit\u00e4tsorientierte Therapiestrategie im Sinne eines Treat-to-Target-Ansatzes. Durch eine breite Auswahl von zielgerichteten Therapien und die Verbesserung des pathophysiologischen Verst\u00e4ndnisses der Erkrankung treten personalisierte Behandlungsstrategien stark in den Mittelpunkt des Therapiemanagements.\n\nID: 42274906\nTitle: Environmental Factors Drive Neurodegenerative Diseases Through Glutamate Excitotoxicity: A Convergent Mechanistic Pathway.\nAbstract: This review illustrates how environmental stressors disrupt glutamate homeostasis via specific mechanisms: lead-induced thiol modification, manganese mediated yin yang 1 (YY1)-histone deacetylases (HDAC) repression, PM2.5-triggered microglia-astrocyte crosstalk, and advanced glycation end products (AGEs)-receptor for advanced glycation end products (RAGE)-nuclear factor kappa-B (NF-\u03baB) signaling from high-sugar diets. Together with genetic susceptibility and pigment epithelium-derived factor (PEDF), these factors impair astrocytic glutamate uptake, promoting synaptic glutamate accumulation. Subsequent N-methyl-D-aspartate (NMDA) and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptor overactivation triggers calcium overload, mitochondrial dysfunction, oxidative stress, and neuroinflammation-termed \"degenerative excitotoxicity\". Excitotoxicity manifests in Alzheimer's disease (amyloid-beta-excitatory amino acid transporter 2 (EAAT2) interplay), Parkinson's disease (subthalamic nucleus-driven excitatory storm), and amyotrophic lateral sclerosis (astrocytic failure versus neuronal cell-autonomous mechanisms). Future interventions need multi-target strategies, emerging technologies, and lifestyle modifications. This convergent framework offers a unified understanding linking environmental exposure to neurodegeneration and charts a roadmap toward mechanism-based prevention and treatment.\n\nID: 42274592\nTitle: The Role of Iron in Neuronal Homeostasis: A Double-Edged Sword.\nAbstract: Iron is an essential micronutrient that plays a central role in numerous biological processes. Despite its relatively low abundance in the human body, iron is particularly critical for brain function. Systemic and cerebral iron homeostasis is tightly regulated through coordinated mechanisms involving absorption, transport, storage, and recycling. Within the brain, iron metabolism is further controlled by the blood-brain barrier and specialized neural cell populations, including neurons, astrocytes, oligodendrocytes, and microglia. Iron is indispensable for neurodevelopment, supporting neurogenesis, myelination, and neurotransmitter synthesis. However, both iron deficiency and iron overload have detrimental consequences. Early-life iron deficiency disrupts neural development and leads to long-lasting cognitive, motor, and behavioral impairments, whereas excessive iron accumulation promotes oxidative stress, ferroptosis, and neuroinflammation. These mechanisms have been described to contribute to the pathogenesis of major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, neurodegeneration with brain iron accumulation, and amyotrophic lateral sclerosis. This review first outlines systemic and brain iron metabolism, highlighting how neural cells regulate homeostasis. Next, it examines iron's physiological roles, particularly in neurogenesis and neurodevelopment. Finally, it explores iron's involvement in neurodegenerative diseases, emphasizing neuroinflammation as a primary mechanism of iron toxicity.\n\nID: 42274555\nTitle: Polypharmacology of Pathway Crosstalk in Neurodegenerative Diseases: Chemical Modulation of Interconnected Signaling Networks.\nAbstract: Neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), arise from highly interconnected molecular and cellular abnormalities that progressively lead to neuronal dysfunction, synaptic failure, and cell death. This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.\n\nID: 42273832\nTitle: Remote, self-administered, smartphone cognitive testing in a registry-based cohort: Feasibility, reliability, and validity findings.\nAbstract: Remote, smartphone-based cognitive testing may improve access to cognitive assessments for Alzheimer's disease and related dementias. We evaluated the feasibility, reliability, and validity of unsupervised smartphone-based cognitive tests in a registry-based cohort. Adults without a record of cognitive impairment (N\u00a0=\u00a01815; ages 18-92) were recruited from the University of California, San Francisco (UCSF) Brain Health Registry to complete three unsupervised smartphone cognitive testing sessions within 2 weeks. Reliability was assessed with correlations between sessions. Linear regression models tested associations of smartphone tasks with demographics, self- and informant-rated cognitive concerns, and web-based cognitive testing (Cogstate Brief Battery). Adherence was high (82.2%) and usability favorable. Test-retest reliability was moderate to strong (\u03c1's\u00a0=\u00a00.61-0.85, all p's\u00a0<\u00a00.001). Lower smartphone scores were associated with older age, lower education, cognitive concerns, and worse Cogstate performance. Findings support the feasibility, reliability, and validity of remote digital assessments in adults without a record of cognitive impairment.\n\nID: 42273805\nTitle: Place of death outcomes of home ventilation patients in Singapore: a retrospective cohort study using a linked database.\nAbstract: Singapore's Home Ventilation and Respiratory Support Service (HVRSS) provides care for patients with chronic respiratory failure needing long-term home ventilation. Currently, data on the distribution of places of death (PODs) among these patients is lacking. We examined the distribution of POD among deceased HVRSS patients over a 10-year period and explored clinical factors potentially associated with specific death locations. Additionally, we assessed the agreement between patients' preferred POD (PPOD), as documented in Advance Care Planning (ACP), and their actual POD. We conducted a retrospective cohort study of patients with at least one HVRSS encounter and who had died by 2019. Death-related information was obtained from an administrative dataset and linked with socio-demographic, clinical, and ACP data from other sources. Logistic regression was used to identify clinical factors associated with specific POD. Agreement analysis between actual POD and PPOD was performed among decedents with valid ACP documentation. Among 118 patients studied, 44% died at home, 53% in hospitals, and 3% elsewhere. ACP documentation was available for 52 patients (44.1%), with 73.1% of those preferring home as their POD. Clinical factors associated with home as POD included diagnosis of motor neuron disease (MND) [odds ratio (OR) =5.6; 95% confidence interval (CI): 1.2-25.0; P=0.02], ventilation status at death (OR =14.9; 95% CI: 3.8-58.3; P<0.001), and feeding type at death (OR =3.8; 95% CI: 1.0-14.0; P=0.044). The percentage agreement between actual POD and PPOD was 57.1% (95% CI: 43-72%; P<0.001) with a Gwet's AC1 coefficient of 0.49 (95% CI: 0.31-0.66; P<0.001), indicating moderate agreement. This is the first study in Singapore to characterise POD patterns and associated factors among home ventilation patients, as well as to evaluate alignment between preferred and actual POD. These findings may inform policy and end-of-life care practices to better support HVRSS patients, particularly at their chosen POD.\n\nID: 42268433\nTitle: FUS-associated ALS in Taiwan: genetic spectrum, clinical features, and a founder haplotype of p.H517D.\nAbstract: To characterize the genetic spectrum and clinical features of FUS-associated amyotrophic lateral sclerosis (ALS) in a Taiwanese cohort and to investigate whether the recurrent p.H517D variant represents a founder mutation. All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.\n\nID: 42264545\nTitle: Nanotechnology-enabled targeting strategies for neurodegenerative disorders: role of functionalized nanoparticles.\nAbstract: Neurodegenerative disorders comprise a diverse group of progressive neurological diseases characterized by the gradual loss of neuronal structure and function. Conditions such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis arise from multifactorial mechanisms involving genetic susceptibility, environmental factors, and age-related cellular decline. Key pathogenic processes include oxidative stress, mitochondrial dysfunction, protein misfolding and aggregation, impaired axonal transport, Golgi fragmentation, and chronic neuroinflammation, all of which disrupt neuronal homeostasis and synaptic communication, ultimately leading to neuronal death. Hormonal imbalances further exacerbate these effects by promoting oxidative damage, inflammation, and metabolic dysfunction. Despite advances in understanding disease mechanisms, effective drug delivery remains challenging due to the restrictive nature of the blood-brain barrier. Recent developments highlight the potential of nanoparticle-based drug delivery systems to overcome these limitations. Functionalized nanoparticles enhance blood-brain barrier penetration, improve targeting specificity, and enable controlled drug release. These systems can deliver neuroprotective agents, antioxidants, peptides, and gene therapies directly to affected brain regions. Thus, integrating disease pathophysiology with nanotechnology-based strategies offers a promising approach for improving therapeutic outcomes and advancing precision treatment in neurodegenerative disorders.\n\nID: 42405014\nTitle: Cholesterol in amyotrophic lateral sclerosis: a bystander, a biomarker, or a target?\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss. In addition to the different pathogenic mechanisms, in recent years, increasing attention has been directed toward the role of lipid metabolism in ALS pathogenesis, although the clinical relevance of lipid alterations in ALS may differ from their well-established role in cardiovascular disease. This review critically examines the multifactorial relationship between cholesterol and ALS through three perspectives: (1) as a risk factor for disease onset, (2) as a prognostic biomarker of disease progression, and (3) as a potential therapeutic target. Epidemiological and genetic studies suggest a complex and sometimes contradictory association between lipid profile and ALS risk. Elevated LDL-cholesterol and total cholesterol have been linked to increased disease susceptibility in some cohorts, with Mendelian randomization studies supporting a potential causal role. Conversely, evidence regarding HDL-cholesterol remains conflicting and may be influenced by sex-specific and metabolic factors. As a prognostic biomarker, hyperlipidemia has been variably associated with prolonged survival in ALS patients; however, these findings often lose significance after adjusting for body mass index and nutritional status, suggesting that lipid levels may reflect systemic metabolic reserve rather than directly modulating disease progression. Pharmacological modulation of cholesterol reveals further complexity. While statins are generally not associated with increased ALS risk in clinical studies, preclinical models show divergent effects: some statins accelerate disease progression, while others like lovastatin may be protective. Other lipid-lowering drugs, including fibrates and PCSK9 inhibitors, may also influence ALS-related pathways beyond cholesterol lowering, although their potential role remains to be clarified.\n\nID: 42404435\nTitle: Value of synaptic proteins as biomarkers in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a heterogeneous and rapidly progressing neurodegenerative disorder with limited treatment options. Therefore, there is a critical need for biomarkers that capture the diverse pathophysiological mechanisms underlying disease onset and progression. Emerging evidence suggests that synaptic dysfunction is an early disease mechanism in amyotrophic lateral sclerosis. Using homebrew immunoassays, we explored a panel of pre- and post-synaptic proteins in cerebrospinal fluid of patients with amyotrophic lateral sclerosis (N = 57) and controls (N = 36). The potential value as a biomarker was explored by correlating cerebrospinal fluid levels with clinical parameters and established biomarkers for amyotrophic lateral sclerosis. Higher levels of Neurogranin (NRGN) (P = 0.003) and Vesicle-associated membrane protein 2 (VAMP2) (P = 0.014) were observed in patients with amyotrophic lateral sclerosis compared with controls. VAMP2, Synaptosome-associated protein 25\u2005kDa (SNAP25) and \u03b2-synuclein (SNCB) correlated with individual relative disease stage, but none of the biomarkers correlated with disease progression rate. High levels of SNAP25 predicted worse survival in a univariate and stepwise multivariable analysis, but significance did not persist upon including Neurofilament light chain (NfL) levels. Synaptic proteins did not correlate with cerebrospinal fluid levels of neurofilaments or biomarkers of neuroinflammation, suggesting that they reflect different pathological mechanisms in amyotrophic lateral sclerosis. Our findings warrant further investigation to determine whether increased cerebrospinal fluid levels of synaptic proteins reflect synaptic breakdown or active release of synaptic proteins. This will help elucidate how synaptic dysfunction or damage contributes to elevated levels of synaptic markers in amyotrophic lateral sclerosis, and its underlying value as biomarker.\n\nID: 42397462\nTitle: A case study of comprehensive association analysis and risk prediction of amyotrophic lateral sclerosis in a Chinese population.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease with significant genetic heterogeneity. While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients.\n\nID: 42392979\nTitle: Deletion of exon 2 in ALS-linked Sptlc1 causes lethality in homozygous mice but not in heterozygotes.\nAbstract: Mutations in the human SPTLC1 gene have recently been linked to early-onset amyotrophic lateral sclerosis (ALS), characterized by global atrophy, motor impairments, and symptoms such as tongue fasciculations. All known ALS-linked SPTLC1 mutations cluster within exon 2, and a specific variant, c.58G>T, results in exon 2 skipping. However, it is unclear how the exon 2 deletion affects SPTLC1 function in vivo and contributes to ALS pathogenesis. Leveraging the high genomic sequence similarity between mouse and human SPTLC1, we created a novel knock-in mouse model with a CRISPR/Cas9-mediated deletion of exon 2 in the endogenous murine Sptlc1 locus. Although heterozygous mice did not develop motor defects or ALS-like neuropathology, homozygous mutants died prematurely. These findings provide valuable insights into SPTLC1 exon 2 biology and serve as a useful resource for future mechanistic studies.\n\nID: 42389758\nTitle: Limitations of Current Therapies and Barriers in Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) remains a major global health crisis due to its complex pathophysiology and limited therapeutic effectiveness. Despite advances in understanding key mechanisms such as amyloid-beta accumulation, tau pathology and neuroinflammation, current therapies provide limited clinical benefit. Multiple factors contribute to limitations and highlight the difficulty of translating scientific advancements into meaningful improvement in patient outcomes. This article provides a comprehensive and critical review of therapeutic, biological, clinical, and systemic barriers to effective Alzheimer's disease management as well as showcasing emerging strategies aimed to improve early detection, treatment approaches, and overall disease prevention.\n\nID: 42387889\nTitle: Identification of spastic muscles involved in abnormal joint posture in patients with upper motor neuron syndrome: a narrative review.\nAbstract: Few studies have specifically investigated which muscles are involved in abnormal joint posture (AJP) due to muscle spasticity and should therefore be targeted for botulinum toxin injections. This gap has significant implications for treatment efficiency, safety, health economics, and sustainable healthcare. A 2000 to 2025 (July) PubMed search identified 3,488 articles, but only 7 articles met the criteria for providing a method to determine the muscles involved in AJP due to muscle spasticity. Of these, just 2 have proposed how to measure each muscle contribution and only 1 focused on identifying the muscle actually responsible for the observed AJP. There are many strategies for determining the muscles involved in spasticity-related AJP, but they are primarily based on inference. They draw on clinical skills, which incorporate descriptive and functional anatomy, knowledge of different muscle and joint structures, simple rules of biomechanics, determination of the exact phase of the movement involved, consideration of compensatory AJP in these motor control deficient patterns, and, of course, the patient's goals. Achieving the authors' proposed objective would enable the standardization of clinical practices, confirm the effectiveness of treatments for spasticity, particularly botulinum toxin, and ensure that the correct dose is injected in the right muscle.\n\nID: 42385702\nTitle: Recurrent patterns of TOP1-mediated neuronal genomic damage shared by major neurodegenerative disorders.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.\n\nID: 42379387\nTitle: Brain mineral concentrations in canine cognitive dysfunction.\nAbstract: Canine cognitive dysfunction (CCD) is a prevalent age-related neurodegenerative condition in dogs that shares several features with Alzheimer's disease (AD). Although mineral dyshomeostasis has been implicated in the pathogenesis of AD, its role in CCD remains largely unexplored. This retrospective study aimed to investigate regional brain mineral concentrations in 24 dogs with CCD and 15 dogs exhibiting successful cognitive aging (non-CCD). CCD diagnosis was based on the results of caregiver questionnaires, physical examination and laboratory analyses after ruling out any other intracranial disease. Four cortical regions with high \u03b2-amyloid pathology (prefrontal, parietal, temporal and occipital cortex) and one generally unaffected region (cerebellum) were analysed to determine the concentrations of 20 minerals by using plasma-based optical techniques and mass spectrometry. Compared to non-CCD dogs, CCD dogs had significantly lower concentrations of Ca, Fe, Mg, Mn and Zn, and higher levels of Cd, Mo, Ni and Pb in specific brain regions. The greatest number of significant differences were observed in the prefrontal cortex, the earliest and most consistently affected region in CCD, whereas the cerebellum remained largely unchanged. Principal component analysis distinguished CCD from non-CCD dogs and, within the CCD group, showed clustering of the cerebellum separately from cortical regions. The regional specificity of these alterations and their ability to distinguish CCD from non-CCD dogs support a link between disrupted mineral homoeostasis and CCD. Notably, lower concentrations affected essential trace elements involved in antioxidant defence, neuronal signalling and neurotransmission, raising the possibility of functional implications that warrants further investigation.\n\nID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown. Together, these findings provided important insights into disease mechanisms and potential avenues for improved clinical management.\n\nID: 42352579\nTitle: Transcranial Focused Ultrasound Stimulation for Alzheimer's Disease-A Scoping Review.\nAbstract: Background/Objectives: Alzheimer's disease (AD) remains a significant global health challenge, characterised by a persistent resistance to traditional pharmacological interventions. While non-invasive brain stimulation (NIBS) techniques like transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) show therapeutic promise, their limited depth of penetration restricts their efficacy in targeting deep-brain AD pathology. Transcranial focused ultrasound stimulation (tFUS) has emerged as a novel, non-invasive neuromodulatory tool capable of precise deep-brain targeting. This scoping review aims to systematically map the current evidence base regarding the neuromodulatory application of tFUS in AD. Methods: Following PRISMA-ScR guidelines, a scoping search was conducted across four major databases (Ovid MEDLINE, Embase, Web of Science, and CENTRAL). Studies were included if they investigated focused ultrasound stimulation (FUS) as a neuromodulatory intervention for AD, excluding applications involving blood-brain-barrier disruption via microbubbles. Two independent reviewers performed screening and data extraction, with inter-rater reliability assessed via Cohen's kappa. Results: Our analysis indicates that tFUS represents a safe and potent multi-modal intervention for AD that addresses both pathological protein aggregation and electrophysiological network failure. Its ability to modulate neuroplasticity and metabolic recovery suggests a promising therapeutic trajectory. Conclusions: Future research should prioritise the standardisation of acoustic protocols and the pursuit of longitudinal clinical cohorts to establish the long-term efficacy of this non-invasive technology.\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42347120\nTitle: RNA-Binding Proteins in Ageing and Age-Related Disease.\nAbstract: RNA-binding proteins (RBPs) are essential regulators of all aspects of RNA metabolism, including splicing, stability, localisation, translation, and degradation. Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.\n\nID: 42341041\nTitle: IRE1 regulates the proteostasis of TDP-43/TARDBP in ALS/FTD through ribosome-associated quality control.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are progressive neurodegenerative disorders characterized by motor neuron degeneration, leading to muscle weakness, atrophy, and cognitive impairments. A defining pathological hallmark of ALS/FTD is the cytosolic mislocalization and accumulation of TAR DNA-binding protein 43 (TDP-43), highlighting its critical role in ALS pathogenesis. However, the molecular mechanisms underlying TDP-43 proteostasis remain poorly understood. Through a genetic screening approach, we identify inositol-requiring enzyme 1 (IRE1), an endoplasmic reticulum-resident transmembrane protein, as a potent suppressor of TDP-43 protein levels. Furthermore, we show that ribosome-associated quality control (RQC) factors play a crucial role in regulating TDP-43 proteostasis and cellular toxicity. Activation of the RQC pathway prevents excessive accumulation of TDP-43 and associated toxicity. Mechanistically, our findings suggest that IRE1 regulates TDP-43 protein level by promoting the degradation of aberrant TDP-43 translation product through the RQC pathway. IRE1 acts canonically to enhance the transcription of the RQC core component Clbn/NEMF and noncanonically to physically interact with Clbn/NEMF, thereby ameliorating TDP-43-induced proteotoxicity. Moreover, ectopic expression or pharmacological activation of IRE1 alleviates TDP-43 pathology and restores cognitive function in the TDP-43 A315T ALS mouse models. Collectively, our study identifies a role for IRE1 in the translational quality control of TDP-43 and establishes its potential as a therapeutic target for ALS/FTD.\n\nID: 42337904\nTitle: Are patient-derived models of amyotrophic lateral sclerosis a game changer for novel drug discovery?\nAbstract: ALS drug discovery has long depended on model systems that incompletely capture human disease heterogeneity, aging, and TDP-43 proteinopathy. Patient-derived platforms have therefore emerged as increasingly important human-relevant complements to animal and molecular models. This Critical Perspective examines when patient-derived ALS models genuinely change therapeutic decision-making rather than merely add mechanistic insight. The authors then propose a heuristic framework based on disease-relevant phenotype recapitulation, capture of patient-to-patient heterogeneity, and generation of findings that influence therapeutic prioritization or clinical translation. Furthermore, the authors evaluate iPSC-derived motor neurons, directly reprogrammed neurons, glial co-cultures, organoids, neural networks, and organ-chip systems against these conditions, while also addressing aging fidelity, reproducibility, upper motor neuron modeling, and regulatory implementation. Patient-derived models are not yet standalone decision-grade tools for ALS drug development. Their present value lies in functioning as a human-biology filter for target discovery, reverse translation, biomarker development, and patient stratification when used within rigorous, standardized, and clinically linked workflows. The strongest current evidence supports proof-of-principle rather than generalized predictive validity.\n\nID: 42334216\nTitle: Tolerability, Safety and Effectiveness of Sigh Introduction During Non-Invasive Mechanical Ventilation Cycles in Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Respiratory failure is the main cause of death in Amyotrophic lateral sclerosis (ALS), in which the physiological sigh reflex is impaired due to inspiratory muscle weakness. Aim of this study is to assess the tolerability, safety, and effectiveness of adding a sigh cycle to non-invasive mechanical ventilation (NIMV) settings in ALS patients. In this randomized, blind-controlled proof-of concept study, 44 consecutive ALS patients with indication for NIMV were randomized to: Group I: NIMV with Sigh cycles; Group II: NIMV without Sigh. The primary outcome was the reduction in the Oxygen Desaturation Index (ODI); secondary outcomes included: Overnight Oximetry (OvOx), Arterial blood gas (ABG), and Visual Analog Scale (VAS; 0-10) scores to assess sleep quality, symptom intensity, mask interface, and NIMV tolerance. Assessments were conducted at baseline, after NIMV adaptation (T1) and at 1-month follow-up (T2). The Sigh cycle was safe and well tolerated. No significant group differences were observed at T1 or T2 in the primary outcome ODI (median \u0394ODI: Group A:-4.2; Group B:-4.6: p\u2009=\u20090.54), as well as in the OvOx parameters and pO2 and pCO2 ABG values. At T2, secondary analysis showed a significant difference in HCO\u2083- in favor of the Sigh arm (\u0394HCO3 -: -1.60 vs. 1.35\u2009mmol/L, p\u2009=\u20090.042). Exploratory Cox-regression models suggested a potential independent effect of SIGH on survival. Sigh is safe, well tolerated in ALS patients. Although this study did not reach the primary outcome, we also cannot rule out that sigh doesn't benefit the patient.\n\nID: 42329291\nTitle: Targeting mitochondrial dysfunction and neuroprotection in neurodegenerative disorders: emerging therapeutic potential of berberine and polymeric nanoparticle-based delivery systems.\nAbstract: Major neurodegenerative disorders, such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis, are pathologically driven by mitochondrial failure and persistent neuroinflammation. Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique.\n\nID: 42326531\nTitle: A lipidomic based metabolic age score for monitoring the effects of lifestyle and diet on metabolic disease risk.\nAbstract: Biological age scores capture ageing heterogeneity beyond chronological age but are often dominated by lifestyle and environmental exposures, limiting clinical interpretability. We developed an environmentally adjusted metabolic age score (EAmAge) to isolate intrinsic ageing biology relevant to neurodegeneration and chronic disease. Major environmental influences were statistically removed from plasma lipidomic profiles before constructing an age-prediction model using ridge regression. EAmAge was derived in the AusDiab cohort (n = 10,339) and validated across three independent cohorts (BHS, ADNI and ASPREE; total n = 9,835). Compared with an unadjusted lipidomic age model (mAge_orig), EAmAge showed stronger and more consistent associations with incident Alzheimer s disease-related dementia, cardiovascular events and all-cause mortality. EAmAge was also associated with Alzheimer s disease-related biomarkers, including amyloid burden, reduced glucose metabolism and hippocampal atrophy. These findings establish EAmAge as a robust and partially modifiable biomarker that improves risk stratification by disentangling intrinsic metabolic ageing from environmental confounding.\n\nID: 42317073\nTitle: PML as a neuroprotective guardian: Leveraging nuclear protein quality control to mitigate neurotoxicity of an ALS-associated NEK1 variant.\nAbstract: Insoluble protein aggregates are a hallmark of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS). The ubiquitin-proteasome system (UPS) serves as a neuroprotective quality control mechanism that clears aggregates. PML nuclear bodies (NBs) were proposed to serve as hubs for SUMO-primed ubiquitylation and degradation of misfolded proteins. Georgiadou et\u00a0al. provide evidence that an ALS-linked NEK1 truncation mutant is recruited to PML NBs, where it likely undergoes SUMOylation and ubiquitylation. In mice, PML loss exacerbates ALS-like symptoms, while induced PML expression delays disease onset. These findings establish PML as a key regulator of proteostasis and highlight PML induction as a potential therapeutic strategy for ALS and related proteinopathies.\n\nID: 42316568\nTitle: Neuroprotection Through Nature: The Role of Bioactive Phytocompounds in Alzheimer's and Parkinson's Disease.\nAbstract: Neurodegenerative diseases, notably Alzheimer's Disease (AD) and Parkinson's Disease (PD), represent a significant and growing global health burden, characterized by progressive cognitive and motor dysfunction. Despite advances in understanding their multifactorial pathogenesis, current pharmacotherapies primarily provide symptomatic relief and fail to modify disease progression. This review critically evaluates the emerging role of bioactive phytocompounds as multi-target neuroprotective agents in the management of AD and PD, emphasizing mechanistic insights and translational challenges. A comprehensive literature search was conducted in PubMed, Scopus, and ScienceDirect, focusing on both preclinical and clinical studies that investigated the neuroprotective potential of key phytoconstituents, including luteolin, catechin, apigenin, and quercetin, derived from botanicals such as Commiphora wightii (Guggul), Curcuma longa, and Salvia officinalis. Accumulating evidence demonstrates that these phytoconstituents exert potent antioxidant, anti-inflammatory, anti-amyloidogenic, and anti-apoptotic effects. Mechanistically, they modulate critical signalling pathways implicated in neurodegeneration, including attenuation of oxidative stress, suppression of pro-inflammatory cytokines (e.g., TNF-\u03b1, IL-6), mitochondrial stabilization, inhibition of acetylcholinesterase activity, and prevention of amyloid-\u03b2 aggregation. Their pleiotropic actions position them as promising adjuncts or alternatives to current mono-targeted therapies. However, clinical translation remains constrained by poor bioavailability, lack of standardisation, and limited pharmacokinetic profiling. Phytocompounds show pleiotropic mechanisms (antioxidant, anti-inflammatory, anti-amyloidogenic) but clinical translation is limited by pharmacokinetic and standardisation barriers; novel delivery systems and rigorous clinical trials are required. Phytocompounds represent a compelling, multi-target strategy for AD and PD management, yet significant barriers to clinical application persist. Future research should focus on the development of advanced drug delivery platforms (e.g., nanoformulations), robust clinical trials, and standardized phytopharmaceutical preparations to validate efficacy and safety. Integrative therapeutic frameworks combining phytochemicals with existing pharmacotherapies may offer a viable path toward disease modification in neurodegeneration.\n\nID: 42311451\nTitle: Affective and cognitive theory of mind and associated brain functional alterations in frontotemporal dementia.\nAbstract: Theory of mind (ToM), the ability to infer others' beliefs (cognitive ToM) and emotions (affective ToM), is compromised in behavioural variant frontotemporal dementia (bvFTD). However, its diagnostic and prognostic value in other frontotemporal dementia (FTD) variants remains underexplored due to limited understanding of the underlying neural mechanisms. This study investigated whether ToM deficits are shared across the frontotemporal dementia spectrum and explored the functional connectivity alterations underlying these disturbances using resting-state functional magnetic resonance imaging. Sixty-seven FTD patients [14 non-fluent variant primary progressive aphasia (nfvPPA), 17 semantic variant primary progressive aphasia (svPPA), 23 bvFTD, 13 right temporal variant frontotemporal dementia (rtvFTD); 34 women; mean age 66.5\u202f\u00b1\u202f7.7 years] and two control groups (48 age-matched healthy controls; 50 young healthy controls) underwent clinical, neuropsychological and brain magnetic resonance imaging assessments. ToM was evaluated in patients using the Story-Based Empathy Task (SET), which includes the Story-Based Empathy Task affective subtest (SET-EA) and the Story-Based Empathy Task cognitive subtest (SET-IA). Resting-state functional connectivity networks were obtained in young healthy controls using seed-based analysis centred on the left medial prefrontal cortex for affective ToM and the right supramarginal gyrus for cognitive ToM. In addition, four large-scale functional networks were reconstructed to reflect disease-specific vulnerability. Functional brain connectivity within all networks was quantified using graph analysis and connectomics, and between-group comparisons were performed on both global and seed-based regional metrics. All patient groups showed similar impairments in affective and cognitive ToM performance. Network analyses revealed two dissociable but interconnected ToM systems. Global metrics of network topology indicated increased path length and reduced nodal strength in both ToM networks, particularly in bvFTD and nfvPPA patients (P\u202f<\u202f0.05). Direct seed-based connectivity analyses confirmed widespread functional connectivity reductions from key nodes (e.g. left inferior frontal gyrus, anterior cingulate cortex) in these groups. In contrast, svPPA and rtvFTD cases exhibited relatively preserved functional connectivity within ToM circuits. Correlation analyses revealed associations between cognitive ToM network metrics and global ToM performance, and between functional connectivity in the salience network and behavioural dysfunction. Affective and cognitive ToM abilities are comparably impaired across FTD variants, suggesting that socio-cognitive impairments may represent a core and early feature across the FTD spectrum. Such deficits are mirrored by patterns of functional disconnection within dedicated large-scale networks, with bvFTD and nfvPPA showing the most pronounced disruptions. This study underscores the diagnostic relevance of socio-cognitive markers and highlights their potential as clinical and biomarker targets in future therapeutic interventions.\n\nID: 42299015\nTitle: Amyotrophic Lateral Sclerosis: Therapeutic Innovations and Evolving Regulatory Approaches.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive degeneration of upper and lower motor neurons, leading to muscle weakness, paralysis, and respiratory failure. Despite extensive research, riluzole and edaravone remain the only globally approved disease-modifying therapies, offering modest survival benefits. This review summarizes current understanding of ALS pathogenesis, approved pharmacological treatments, and emerging gene-, RNA-, and cell-based therapeutic strategies. Particular emphasis is placed on regulatory considerations and evolving clinical trial designs in ALS drug development. The accelerated approval and subsequent withdrawal of sodium phenylbutyrate-taurursodiol (AMX0035) are discussed as a critical case study highlighting the challenges of regulatory flexibility in rare, fatal diseases. Advances in biomarker development, especially neurofilament light chain, are examined for their growing role in trial design and therapeutic evaluation. Collectively, these insights underscore a shift toward biomarker- informed and precision-based approaches that may improve future ALS therapeutic development.\n\nID: 42288852\nTitle: Cognitive, biomarker, and neuroimaging indices associated with traumatic encephalopathy syndrome across two independent athlete cohorts.\nAbstract: Traumatic encephalopathy syndrome (TES) is a clinical research construct used to identify individuals at risk for chronic traumatic encephalopathy (CTE) following exposure to repetitive head impacts (RHI). Adjudication of TES relies on clinical features such as progressive cognitive impairment and neurobehavioral dysregulation. Blood-based biomarkers and structural neuroimaging abnormalities have been associated with TES but are not part of the criteria. This study evaluated whether TES identification was associated with the combined contribution of cognitive performance, blood biomarkers, and structural neuroimaging measures across two well-characterized cohorts. Participants included 158 professional fighters from the Professional Athletes Brain Health Study and 149 former American football players from The DIAGNOSE CTE Research Project. Three indices were constructed representing complementary domains: a cognitive index reflecting cohort-specific cognitive features, a blood biomarker index including plasma neurofilament light chain, glial fibrillary acidic protein, total tau, tau phosphorylated at amino acid 231, and APOE-\u03b54 carrier status, and an imaging index comprising volumetric MRI measures of subcortical structures, ventricles, and corpus callosum subregions. Grouped weighted quantile sum regression models were estimated within each cohort to evaluate associations between these indices and TES while adjusting for age, race, competition status, and RHI exposure. Multidomain models demonstrated improved model performance compared with single-domain models in both cohorts (PABHS: AUC\u2009=\u20090.91, PPV\u2009=\u20090.80; DIAGNOSE CTE: AUC\u2009=\u20090.84, PPV\u2009=\u20090.85). Biomarker and imaging indices contributed additional information across cohorts, although imaging contributions were more prominent in fighters whereas blood biomarker associations were stronger in football players. TES in RHI-exposed athletes was associated with a convergent clinicobiological profile observed across two independent cohorts with distinct exposure patterns. These findings support multidomain analytic frameworks for evaluating correlated biological signals in RHI-exposed populations and may inform future studies of TES and CTE.\n\nID: 42283497\nTitle: The Long Haul: Microtubule Motors as the Essential Supply Line for Neuronal Longevity.\nAbstract: The extreme morphology and polarised architecture of neurons require the highly sophisticated microtubule transport system for both construction and lifelong survival. Genomic evidence from an expanding landscape of human mutations supports the essential role of the microtubule transport machinery. During neurodevelopment, mutations disrupt the proliferation and migration of neuronal precursors, as well as the initial establishment of polarity. In the mature nervous system, the reliance on microtubule transport shifts to the long-term maintenance of axon integrity and synaptic proteostasis. Across the motor proteins responsible for long distance transport in neurons, mutations highlight a specific vulnerability of long axons to transport failure in Hereditary Spastic Paraplegia (HSP), Charcot Marie Tooth disease Type 2 (CMT2), Spinal Muscular Atrophy (SMA), Perry Syndrome, and Amyotrophic Lateral Sclerosis (ALS) amongst others. Due to the role of microtubule motors in development and maintenance, there is frequently a phenotypic spectrum within a single gene of the microtubule transport system. For example, mutations in dynein motors are linked both to malformations of cortical development and specific motor neuron loss in SMA-LED (Spinal Muscular Atrophy with Lower Extremity Predominance). By synthesising genetic evidence, this review illustrates how specific molecular failures, ranging from motor-domain kinetics to cargo binding, can inform our understanding of neuronal homeostasis. Ultimately, we argue that microtubule transport is not merely a cellular utility, but a key determinant of neuronal longevity.\n\nID: 42282797\nTitle: PAD2 knockout reduces myelin protein aggregates, modulates neuroinflammation and protects motor neurons, axons and neuromuscular junction in a SOD1-ALS mouse model.\nAbstract: Dysregulated peptidyl deiminase 2 (PAD2) and aberrant protein citrullination (PC), a posttranslational modification (PTM), are involved in various inflammatory and neurodegenerative diseases. We previously showed in transgenic mice and postmortem human tissues that PC and PAD2 are altered in amyotrophic lateral sclerosis (ALS), a neurodegenerative disease characterized by motor neurons loss, paralysis, and death. Herein, we investigated the role of PAD2 in ALS by PAD2 knockout in a SOD1-ALS mouse model. To investigate the role of PAD2-induced citrullination in ALS pathogenesis, we generated PAD2 knockout (PAD2KO) in SOD1 G93A ALS mouse model and investigated the consequent modulation on the neuropathology and clinical symptoms, using molecular biology techniques such as qPCR, Western blotting, confocal microscopy, and electron microscopy. Additionally, we identified C3 as being citrullinated in human ALS using ionFinder. Our results show that PAD2KO blocked the increased PC and reduced myelin basic protein (MBP) aggregates in the ALS model. PAD2KO also improved motor neuron survival and the integrity of myelin, axons, and neuromuscular junctions, and reduced microgliosis in the white matter and C3 protein levels in astrocytes. Clinically, data from monitoring the body weight changes suggests that PAD2KO modulates the course of the disease in the ALS mouse model, accelerating the onset while slowing the progression after the onset, and modestly extending the survival of male mice. These results show that PAD2 is responsible for the increased PC in ALS and PC contributes to neuroinflammation and degeneration of motor neurons and myelinated axons. The modest modulation of the disease phenotype suggests that the role of PC in ALS is complex, involving altered PC in numerous proteins and in multiple cell types. Future studies are needed to investigate how PC modulates individual protein functions in various cell types to understand the contribution of PC to ALS pathogenesis.\n\nID: 42280341\nTitle: The Role of Polyphenols on Cognitive Function and Dementia Through Gut-Microbiota-Brain Axis Modulation: A Narrative Review.\nAbstract: The number of individuals affected by dementia and cognitive decline is progressively increasing, becoming a serious global health challenge. Several investigations underline the role of nutrition and dietary habits as a preventive strategy. Recent studies suggest that dietary supplementation with polyphenols may constitute an efficient preventive strategy. Indeed, it is emerging that polyphenols exhibit a neuroprotective effect because of their pronounced antioxidant and anti-inflammatory activity. Notably, several studies underline the role of the gut microbiota in the metabolism of the polyphenols, producing bioactive molecules that are absorbed through the gastrointestinal tract. They may exhibit beneficial effects on the central nervous system. Moreover, dietary polyphenols modulate gut microbiota composition, demonstrating a reciprocal regulation between gut microbiota and polyphenol-induced effects on brain functions. Thus, polyphenols are proposed to have an important role on the gut-microbiota-brain axis regulation. The literature search for this narrative review was conducted across three electronic databases PubMed, Scopus, and Web of Science as well as the NIH ClinicalTrials.gov registry, covering the period from January 2000 to 10 February 2026. The following search terms were used: \"polyphenols\", \"microbiota\", \"gut-brain axis\", \"dementia\", \"cognitive function\", \"polyphenols and cognitive dysfunction\", and \"polyphenols and microbiota\". The study selection process was performed in two sequential stages: (i) screening of titles and abstracts, followed by (ii) full-text assessment for eligibility. Articles were included if they were peer-reviewed studies (in vitro, in vivo, or clinical trials), published in English, and addressed the effects of polyphenols on cognitive outcomes, gut microbiota composition, or the gut-microbiota-brain axis. Exclusion criteria included non-peer-reviewed sources, studies lacking relevant cognitive or microbiota-related endpoints, and publications not available in full.\n\nID: 42274734\nTitle: [Anti-infectious cross-linking: when and how? : PACK-CXL as treatment option for infectious keratitis].\nAbstract: Infectious keratitis remains a\u00a0major cause of blindness worldwide. Conventional antimicrobial treatment is not always sufficient, particularly against drug-resistant pathogens. Photoactivated chromophore for keratitis-corneal cross-linking (PACK-CXL) offers a\u00a0promising adjunctive or alternative treatment. Narrative review based on the current literature and clinical experience, covering mechanisms of action, clinical evidence, protocol selection and practical decision-making criteria for PACK-CXL. The PACK-CXL acts via three mechanisms: direct killing of pathogens through reactive oxygen species (ROS), increased resistance to protease digestion through steric hindrance and anti-inflammatory effects. Clinical studies demonstrated that adjuvant PACK-CXL shortens the healing time and as monotherapy achieves approximately 89% success in small bacterial ulcers. Higher total radiation doses (high fluence, \u2265\u202f7.2\u202fJ/cm2) are more effective than the standard protocol (5.4\u202fJ/cm2). For Acanthamoeba keratitis, a\u00a0sequential dual chromophore strategy (riboflavin/UV followed by Rose bengal/green light) shows promising results. The use of PACK-CXL enables rapid, largely pathogen-independent treatment of infectious keratitis. Protocol selection should be guided by ulcer size, depth and pathogen type. Accelerated high-fluence protocols are particularly suitable for antimicrobial use. HINTERGRUND: Die infekti\u00f6se Keratitis stellt weltweit eine h\u00e4ufige Ursache f\u00fcr rechtliche Erblindung dar. Herk\u00f6mmliche Therapien mit Breitspektrumantimikrobiotika sind nicht immer ausreichend wirksam, insbesondere bei therapieresistenten Erregern. Das photoaktivierte Chromophor-Keratitis-Crosslinking (PACK-CXL) bietet eine vielversprechende Erg\u00e4nzung oder Alternative zur konventionellen Therapie. Die \u00dcbersichtsarbeit basiert auf aktueller Literatur und klinischer Erfahrung. Es werden die Wirkmechanismen, klinische Evidenz, Protokollwahl und praktische Entscheidungskriterien f\u00fcr PACK-CXL dargestellt. PACK-CXL wirkt \u00fcber 3\u00a0Mechanismen: direkte Pathogenabt\u00f6tung durch reaktive Sauerstoffspezies (ROS), erh\u00f6hte Resistenz gegen Proteaseverdauung durch sterische Behinderung und antiinflammatorische Effekte. Klinische Studien zeigen, dass PACK-CXL als adjuvante Therapie die Heilungszeit verk\u00fcrzt und als Monotherapie bei kleinen bakteriellen Ulzera eine Erfolgsrate von 89\u202f% erreicht. H\u00f6here Gesamtstrahlendosen (\u201ehigh fluence\u201c) (\u2265\u202f7,2\u202fJ/cm2) sind wirksamer als das Standardprotokoll (5,4\u202fJ/cm2). Bei Akantham\u00f6benkeratitis zeigt eine sequenzielle Dualchromophor-Strategie (Riboflavin/UV gefolgt von Bengalrosa/Gr\u00fcnlicht) vielversprechende Ergebnisse. PACK-CXL erm\u00f6glicht eine schnelle, weitgehend erregerunabh\u00e4ngige Behandlung infekti\u00f6ser Keratitiden. Die Wahl des Protokolls sollte sich an Ulkusgr\u00f6\u00dfe, -tiefe und Erregertyp orientieren. Beschleunigte High-fluence-Protokolle sind f\u00fcr den antimikrobiellen Einsatz besonders geeignet.\n\nID: 42272365\nTitle: Incidental Radiation Exposure to the Internal Mammary Lymph Nodes in Breast Cancer Patients Undergoing Intensity-Modulated Radiation Therapy: A Retrospective Analysis.\nAbstract: Breast cancer (BC) remains the most common malignancy among Indian women, with Stage III being the most frequent at diagnosis. While radiation therapy (RT) plays a pivotal role in the adjuvant treatment of breast cancer, the inclusion of internal mammary lymph nodes (IMLNs) in the radiation field remains controversial due to potential cardiopulmonary toxicity. However, the extent of incidental radiation to the IMLNs, especially with forward planning intensity-modulated radiation therapy (IMRT), remains under-explored. This study aimed to evaluate the incidental radiation dose received by the IMLNs in patients with leftsided breast cancer treated with forward planning IMRT. A total of 36 left-sided breast cancer patients, aged 35-60 years, who underwent modified radical mastectomy followed by adjuvant RT using IMRT, were retrospectively analyzed. CT-based planning and contouring were performed according to RTOG guidelines, with IMLNs contoured retrospectively using Jetwa et al.'s method. Dosimetric parameters for the planning target volume (PTV) and IMLNs were extracted and analyzed using dose-volume histograms. Statistical comparisons were made using the dependent Student's t-test. The PTV received effective radiation coverage with a mean D95 of 38.47 Gy and a mean Dmean of 40.10 Gy. The IMLNs, although not directly targeted, received significant incidental radiation, with a mean D95 of 8.49 Gy, D50 of 21.59 Gy, and Dmean of 21.40 Gy. The maximum dose to the IMLNs (Dmax) reached 38.14 Gy. Comparative analysis revealed statistically significant differences in both Dmax and Dmean between PTV and IMLNs (p = 0.004 and p < 0.001, respectively). Forward planning IMRT provides substantial incidental radiation exposure to the IMLNs, which may have therapeutic implications in reducing recurrence risk. However, this exposure also necessitates careful consideration of potential long-term toxicities to adjacent organs. Further prospective studies are warranted to evaluate the clinical outcomes associated with incidental IMLN irradiation.\n\nID: 42268401\nTitle: [Shock waves as a\u00a0preventive impulse : New approaches to reducing surgical and postoperative complications, including tissue regeneration].\nAbstract: Extracorporeal shock wave therapy (ESWT) has evolved from its original use in the disintegration of kidney stones to become an innovative therapeutic modality in many different medical disciplines. While the focus used to be on treating existing pathologies, the literature now shows a\u00a0growing interest in both prophylactic and preventive applications. This review systematizes the evidence for prophylactic ESWT strategies to prevent or minimize complications from surgical interventions. The article covers applications in orthopedics, dentistry, plastic surgery, and wound healing. Die extrakorporale Sto\u00dfwellentherapie (ESWT) hat sich von ihrer urspr\u00fcnglichen Verwendung zur Desintegration von Nierensteinen zu einer innovativen therapeutischen Modalit\u00e4t in vielen verschiedenen medizinischen Disziplinen weiterentwickelt. W\u00e4hrend fr\u00fcher die Behandlung bereits bestehender Pathologie im Vordergrund stand, zeigt die rezente Fachliteratur ein zunehmendes Interesse an prophylaktischen und pr\u00e4ventiven Anwendungen. Diese \u00dcbersichtsarbeit systematisiert die Evidenz f\u00fcr prophylaktische ESWT-Strategien zur Verhinderung oder Minimierung von Komplikationen nach chirurgischen Interventionen. Der Artikel umfasst dabei unter anderem Anwendungen in der Orthop\u00e4die, Zahnmedizin, plastisch-rekonstruktiven Chirurgie und Wundheilung.\n\nID: 42261162\nTitle: Targeting \u03b1-Synuclein Aggregation in Parkinson's Disease: A Narrative Review of Current Gene Therapy Strategies.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the accumulation of misfolded \u03b1-synuclein (\u03b1-syn) aggregates, leading to dopaminergic neuronal loss and motor dysfunction. Current pharmacological treatments primarily provide symptomatic relief and have a limited impact on disease progression. This article presents a narrative review of emerging gene therapy approaches aimed at modulating \u03b1-syn expression, aggregation, and clearance as potential disease-modifying strategies for PD. Gene-based interventions include viral vector-mediated gene delivery, antisense oligonucleotides, RNA interference, and gene-editing technologies. Preclinical studies and early-phase clinical trials suggest that these approaches may reduce \u03b1-syn burden, improve motor outcomes, and support dopaminergic neuron preservation. Adeno-associated viral and lentiviral vectors have demonstrated promise for targeted central nervous system delivery, although challenges related to dosage optimization, regional specificity, long-term safety, and immune responses remain. Complementary strategies focusing on enhancing molecular chaperone activity and activating autophagy-lysosomal pathways have also shown potential in facilitating \u03b1-syn clearance. Despite encouraging progress, several limitations hinder clinical translation, including off-target effects, immune activation, and the need to preserve physiological \u03b1-syn functions essential for neuronal homeostasis. Future success will depend on precise molecular targeting, optimized delivery platforms, and rigorous safety evaluation through well-designed clinical trials. This narrative review summarizes current advances, key limitations, and future directions in \u03b1-syn-targeted gene therapy, highlighting its potential role in advancing PD treatment beyond symptomatic management toward disease modification.\n\nID: 42261159\nTitle: The Pivotal Role of HDAC6 in Amyotrophic Lateral Sclerosis: Neuroprotective Protagonist or Degenerative Adversary?\nAbstract: The review specifically examines the pivotal role of HDAC6 in the pathophysiological pathway of Amyotrophic Lateral Sclerosis (ALS), an escalating neurodegenerative ailment marked by the discerning damage to motor neurons. Several lines of evidence implicate inadequate proteostasis in significantly influencing neuronal degeneration. The accumulation of misfolded proteins and proteotoxicity are highlighted as significant factors in ALS pathophysiology. Key pathological hallmarks include ubiquitin-positive inclusions, disrupted RNA metabolism, cytoskeletal perturbations, and compromised axonal transport systems. HDAC6 dysregulation disrupts axonal transport, impairing mitochondrial function and increasing oxidative stress, leading to rapid motor neuron damage and cell death. The enzyme's aberrant deacetylation of \u03b1-tubulin destabilizes microtubules and impairs intracellular trafficking. Despite HDAC6's participation in these unfavorable processes, it also exerts neuroprotective properties. It deacetylates tubulin, promoting efficient axonal transport and autophagic clearance. HDAC6 helps form aggresomes and stress granules, which are essential for cellular defence against proteotoxic stress. Through its zinc finger ubiquitin-binding domain, HDAC6 interacts with polyubiquitinated proteins, facilitating their autophagic degradation. HDAC6 inhibition can boost autophagic flux and reduce protein aggregation, while its activation may amplify the protective effects. This dichotomous behaviour of HDAC6 may pose an obstacle to the design of targeted therapy. Illuminating the complex mechanisms through which HDAC6 influences neurodegeneration and neuroprotection is important before constructing effective treatments for ALS. The review provides a clear understanding of the complex role of HDAC6 in ALS pathogenesis and highlights potential strategies to improve the prognosis of people affected by this neurological illness.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

While age-standardized rates have shown decline in certain regions, the absolute number of cases is escalating due to the interplay of global aging and population growth.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic lateral sclerosis (ALS) is increasingly recognized as a fatal neurodegenerative disease with a global epidemiology characterized by complex variations across age, sex, and geography. Current research indicates that the apparent rise in ALS cases is driven by demographic change. As global populations age, the number of individuals entering the age range of peak incidence (70\u201379 years) increases, leading to a higher total disease burden despite potentially stable or declining age-standardized rates. This demographic transition is particularly evident in studies analyzing longitudinal trends. Furthermore, the role of environmental factors and genetic susceptibility in a predisposed population continues to be investigated as a secondary driver of the disease landscape.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Population aging accounted for 46.0% of the increase in DALYs in China from 1990 to 2021.\n* Age-standardized rates of motor neuron disease have declined in many settings despite rising absolute numbers.\n* The global pooled incidence of ALS is 1.65 per 100,000 person-years.\n* Incidence and prevalence of ALS are significantly lower in females than in males.\n* ALS burden is higher in high-income countries compared to middle-income countries.\n* There is a marked age-dependent pattern for ALS burden, peaking at ages 70-79.\n* Environmental exposure to toxic metals (lead, cadmium, mercury) and chemicals like formaldehyde is linked to neurodegenerative risk.\n* The gut-microbiota-brain axis and dietary factors, including vitamin intake, are increasingly implicated in ALS progression.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While previous systematic reviews existed, an updated comprehensive synthesis is needed to delineate the disease burden. We searched PubMed, Embase, Scopus, Web of Science and Cochrane databases from inception to 18 February 2025, for studies reporting the incidence, prevalence or mortality of ALS in the general population. Pooled estimates with 95% CIs were calculated, and subgroup analyses were performed. Of 29\u2009110 articles initially screened, 142 were included. Global pooled incidence was 1.65 per 100\u2009000 person-years (95% CI 1.43 to 1.91), prevalence was 5.05 per 100\u2009000 population (95%\u2009CI 4.26 to 5.99) and mortality was 1.26 per 100\u2009000 person-years (95%\u2009CI 0.94 to 1.69). Both incidence rate ratio (IRR=0.74) and prevalence rate ratio (PRR=0.69) indicated significantly lower disease burden in females than in males. The burden of disease exhibited a marked age-dependent pattern, peaking at ages 70-79. Temporal trend analyses revealed a consistent increase in prevalence from 1963 to 1999\u2009onwards, while incidence peaked in 2014-2017. Geographically, incidence and prevalence were highest in Europe, North America and Oceania and lowest in Asia and South America. The disease burden was significantly higher in high-income countries compared with both upper-middle-income and lower-middle-income countries. This systematic review provides updated global ALS burden estimates, showing variations by sex, age, time and geography and underscoring the complex interplay of genetic, environmental and socioeconomic factors, with implications for health planning, resource allocation and etiological research."

"abstract_text": "ID: 42404161\nTitle: Perspective and quality of life in amyotrophic lateral sclerosis patients undergoing percutaneous endoscopic gastrostomy.\nAbstract: Percutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS). While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p\u202f>\u202f0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p\u202f>\u202f0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD\u202f=\u202f6.6) to discharge (30.97, SD\u202f=\u202f5.84) and were maintained at 1-month follow-up (30.21, SD\u202f=\u202f6.7; p\u202f=\u202f0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline\u202f=\u202f33.3; 1-month follow-up\u202f=\u202f28.61; p\u202f=\u202f0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline\u202f=\u202f9.63; 1-month follow-up\u202f=\u202f7.38; p\u202f=\u202f0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function."

These diseases result from an interaction between the environment and genetically predisposed individuals. This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf."

Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions."

Patient responses to treatments vary widely, highlighting the need for personalized care. Clustering patients based on disease progression could improve prognosis, guide clinical decision-making, and optimize clinical trial design. This study aimed to identify robust ALS patient clusters using ALS Functional Rating Scale-Revised (ALSFRS-R) scores and to determine diagnostic parameters predictive of cluster membership, enabling earlier stratification and targeted management. Data from the Tours ALS center registry (April 1997-October 2023) were analyzed; after preprocessing, 353 patients monitored every three months between January 2004 and July 2023 with ALSFRS-R, clinical, biological, and demographic data were retained. After preprocessing to handle missing or aberrant data, a weakly supervised approach labeled patient pairs based on their ALSFRS-R sequences. These labels were used to train a classifier to learn a distance for off-the-shelf clustering algorithms. Multiple configurations were tested, varying clustering algorithms, dimensionality reduction method, and number of clusters. Random Forest (RF) model predicted cluster membership from diagnostic parameters. Optimal clustering was selected using silhouette score, validated with Kaplan-Meier survival analysis. Stability and robustness were assessed with the Adjusted Rand Index (ARI) and silhouette score respectively. Predictive performance was evaluated using specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV). Diagnostic parameters associated with clusters were identified using Kruskal-Wallis and chi-squared tests for continuous and categorical variables. Three clusters (n\u2009=\u2009139, 121, 93) were identified, demonstrating strong separation (silhouette\u2009\u2248\u20090.6) and high stability of results (ARI\u2009\u2248\u20090.7). Survival differed significantly among clusters: over 50% of patients in the third cluster survived beyond 50 months, compared to less than 25% in the other clusters. Thirteen diagnostic parameters-including ALSFRS-R subscores, IgG levels, albumin quotient, and time to diagnosis-were key predictors of cluster membership. Cluster prediction achieved specificity and NPV\u2009\u2248\u20090.75, with close sensitivity and PPV compared to state-of-the-art methods. This framework successfully stratifies ALS patients into clinically meaningful clusters, revealing underlying disease heterogeneity and providing strong prognostic insight. Such classification can facilitate personalized care, guide therapeutic decisions, and inform the design of targeted interventions to improve outcomes. Not applicable."

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations."

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations."

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response."

This phenomenon is primarily driven by demographic factors\u2014specifically population ageing and growth\u2014rather than an increase in per-capita disease risk.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe perceived surge in ALS prevalence is a multifaceted epidemiological outcome. Demographic studies conducted over the last two decades provide compelling evidence that the escalation in case numbers is largely a byproduct of an ageing global population. Because ALS incidence peaks at ages 70\u201379, the demographic shift toward longer life expectancies disproportionately increases the size of the high-risk cohort. Furthermore, improved clinical management, such as the use of gastrostomy for nutritional support and better multidisciplinary care, has increased survival rates, thereby inflating the total number of individuals living with the disease at any given time. While environmental factors, genetic risks, and potential changes in ascertainment exist, current meta-analytical evidence suggests that the rising prevalence of motor neuron diseases reflects a true increase in absolute cases driven by demographic expansion and enhanced longevity post-diagnosis.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Population ageing accounts for approximately 46% of the increase in disability-adjusted life years (DALYs) in MND-related studies.\n* Age-standardized rates of MND have actually declined in many settings, suggesting that individual risk may be stable or decreasing.\n* Gastrostomy interventions like PEG or RIG, while primarily nutritional, have been shown to increase survival rates for ALS patients.\n* The global incidence of ALS is 1.65 per 100,000 person-years, with a notably higher disease burden in high-income countries compared to middle-income settings.\n* There is a significant sex disparity in ALS burden, with prevalence rate ratios indicating a lower burden in females compared to males.\n* Improved multidisciplinary palliative care facilitates better referral and intervention timing, indirectly contributing to the survival-driven increase in prevalence.\n* Environmental exposures and dietary factors are increasingly linked to the pathogenesis, suggesting that \"epidemiological shifts\" are complex and interact with demographic changes.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In addition to the different pathogenic mechanisms, in recent years, increasing attention has been directed toward the role of lipid metabolism in ALS pathogenesis, although the clinical relevance of lipid alterations in ALS may differ from their well-established role in cardiovascular disease. This review critically examines the multifactorial relationship between cholesterol and ALS through three perspectives: (1) as a risk factor for disease onset, (2) as a prognostic biomarker of disease progression, and (3) as a potential therapeutic target. Epidemiological and genetic studies suggest a complex and sometimes contradictory association between lipid profile and ALS risk. Elevated LDL-cholesterol and total cholesterol have been linked to increased disease susceptibility in some cohorts, with Mendelian randomization studies supporting a potential causal role. Conversely, evidence regarding HDL-cholesterol remains conflicting and may be influenced by sex-specific and metabolic factors. As a prognostic biomarker, hyperlipidemia has been variably associated with prolonged survival in ALS patients; however, these findings often lose significance after adjusting for body mass index and nutritional status, suggesting that lipid levels may reflect systemic metabolic reserve rather than directly modulating disease progression. Pharmacological modulation of cholesterol reveals further complexity. While statins are generally not associated with increased ALS risk in clinical studies, preclinical models show divergent effects: some statins accelerate disease progression, while others like lovastatin may be protective. Other lipid-lowering drugs, including fibrates and PCSK9 inhibitors, may also influence ALS-related pathways beyond cholesterol lowering, although their potential role remains to be clarified.\n\nID: 42404161\nTitle: Perspective and quality of life in amyotrophic lateral sclerosis patients undergoing percutaneous endoscopic gastrostomy.\nAbstract: Percutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS). While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p\u202f>\u202f0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p\u202f>\u202f0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD\u202f=\u202f6.6) to discharge (30.97, SD\u202f=\u202f5.84) and were maintained at 1-month follow-up (30.21, SD\u202f=\u202f6.7; p\u202f=\u202f0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline\u202f=\u202f33.3; 1-month follow-up\u202f=\u202f28.61; p\u202f=\u202f0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline\u202f=\u202f9.63; 1-month follow-up\u202f=\u202f7.38; p\u202f=\u202f0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function.\n\nID: 42400303\nTitle: Adeno-Associated Virus Gene Therapy for Spinal Muscular Atrophy Induces Hepatotoxicity via Cytokine and Macrophage Activation.\nAbstract: Hepatotoxicity is a common and significant adverse effect associated with adeno-associated virus (AAV) gene therapy; however, the underlying mechanisms remain unknown. In this study, we demonstrated innate immune activation in two patients with spinal muscular atrophy shortly after receiving AAV9 gene therapy with onasemnogene abeparvovec. Both patients developed marked hyperferritinemia accompanied by hepatotoxicity, thrombocytopenia, hypertriglyceridemia, and hypofibrinogenemia, all of which are the diagnostic criteria for macrophage activation syndrome. To evaluate their immune responses, serial analyses of serum cytokines/chemokines and flow cytometry were performed. Surges in macrophage-associated cytokine levels were observed in proportion to the severity of adverse events within 1\u2009week after AAV vector infusion, suggesting that macrophage activation contributed to the pathogenesis of these adverse effects. Our findings clarify the immunological basis underlying hepatotoxicity in patients after AAV gene therapy. Furthermore, these findings provide a rationale for using various immunosuppressants or chemokine blockers in patients exhibiting severe adverse effects.\n\nID: 42399099\nTitle: Global epidemiology of amyotrophic lateral sclerosis: a systematic review and meta-analysis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with the global epidemiological profile remaining incompletely understood. While previous systematic reviews existed, an updated comprehensive synthesis is needed to delineate the disease burden. We searched PubMed, Embase, Scopus, Web of Science and Cochrane databases from inception to 18 February 2025, for studies reporting the incidence, prevalence or mortality of ALS in the general population. Pooled estimates with 95% CIs were calculated, and subgroup analyses were performed. Of 29\u2009110 articles initially screened, 142 were included. Global pooled incidence was 1.65 per 100\u2009000 person-years (95% CI 1.43 to 1.91), prevalence was 5.05 per 100\u2009000 population (95%\u2009CI 4.26 to 5.99) and mortality was 1.26 per 100\u2009000 person-years (95%\u2009CI 0.94 to 1.69). Both incidence rate ratio (IRR=0.74) and prevalence rate ratio (PRR=0.69) indicated significantly lower disease burden in females than in males. The burden of disease exhibited a marked age-dependent pattern, peaking at ages 70-79. Temporal trend analyses revealed a consistent increase in prevalence from 1963 to 1999\u2009onwards, while incidence peaked in 2014-2017. Geographically, incidence and prevalence were highest in Europe, North America and Oceania and lowest in Asia and South America. The disease burden was significantly higher in high-income countries compared with both upper-middle-income and lower-middle-income countries. This systematic review provides updated global ALS burden estimates, showing variations by sex, age, time and geography and underscoring the complex interplay of genetic, environmental and socioeconomic factors, with implications for health planning, resource allocation and etiological research.\n\nID: 42399082\nTitle: Radiologically inserted gastrostomy in advanced amyotrophic lateral sclerosis: clinical outcomes.\nAbstract: To evaluate survival and clinical outcomes in patients with amyotrophic lateral sclerosis (ALS) undergoing radiologically inserted gastrostomy (RIG) and to describe outcomes in patients in whom gastrostomy was indicated but not performed. This retrospective observational cohort study included patients with ALS followed by a multidisciplinary palliative care team between 2018 and 2020. Patients were classified according to gastrostomy status (RIG vs no RIG). Clinical data, respiratory support, nutritional status and survival outcomes were collected from medical records. Survival was analysed from gastrostomy indication using Kaplan-Meier curves stratified by baseline non-invasive ventilation (NIV) use. Among 155 patients with ALS, RIG was indicated in 53 and performed in 45; eight patients died before the procedure. 65 patients did not undergo gastrostomy. Median survival after RIG was 14.7 months, compared with 8 months in non-RIG patients who died. Baseline NIV use was associated with longer survival. No major safety concerns were identified. RIG appears to be a safe and feasible option in advanced ALS. Multidisciplinary care with integrated palliative involvement may facilitate referral, optimise nutritional support and support shared decision-making aligned with patients' goals of care. Further prospective studies are needed to confirm benefits and identify intervention timing.\n\nID: 42394962\nTitle: Decremental responses following repetitive nerve stimulation in spinal and bulbar muscular atrophy.\nAbstract: The presence of decremental responses following repetitive nerve stimulation (RNS) in amyotrophic lateral sclerosis (ALS) is well established. However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3\u00a0Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42393482\nTitle: Diverging trends in motor neuron disease burden in China: an ageing-driven increase despite declining age-standardised rates - a GBD 2021 analysis.\nAbstract: Age-standardised rates of motor neuron disease (MND) have declined in many settings, yet the absolute burden continues to rise in ageing populations. Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations.\n\nID: 42388560\nTitle: Influence of team size on the efficiency of time-critical ALS interventions in prehospital cardiac arrest - A prospective randomised multicentre simulation study.\nAbstract: To determine whether increasing emergency medical service (EMS) team size improves the efficiency of time-critical invasive procedures during advanced life support (ALS) for out-of-hospital cardiac arrest (OHCA). Randomised prospective multicentre simulation study with a parallel-group comparison of four predefined team sizes. Three accredited EMS training centres in North Rhine-Westphalia, Germany. 210 ALS-trained paramedic students allocated to 59 teams of two to five members. Teams managed a standardised adult ALS scenario (persistent ventricular fibrillation) requiring five invasive procedures: manual defibrillation, supraglottic airway insertion, intravenous access, preparation of amiodarone (300\u00a0mg), and preparation of epinephrine (1\u00a0mg). The primary endpoint was total scenario time from start to completion of the final procedure. Secondary endpoints were start and completion times for each intervention. Mean total times (mm:ss) decreased progressively with team size: two-person 6:33\u00a0\u00b1\u00a00:33\u00a0min, three-person 4:13\u00a0\u00b1\u00a00:40\u00a0min, four-person 2:54\u00a0\u00b1\u00a00:24\u00a0min, and five-person 2:14\u00a0\u00b1\u00a00:19\u00a0min (ANOVA, p\u00a0<\u00a00.001). All pairwise differences were statistically significant (Bonferroni-corrected p adj\u00a0<\u00a00.01). Earlier initiation of intravenous access and drug preparation accounted for most time savings. All teams completed every task successfully. Larger EMS teams performed time-critical ALS procedures significantly faster, with optimal efficiency observed in four- to five-member crews. These findings highlight the operational importance of team composition for prehospital resuscitation performance and may inform staffing policies and simulation-based training.\n\nID: 42388397\nTitle: Long-term use of rozanolixizumab in generalised myasthenia gravis: final pooled analysis of the phase III MycarinG study and two open-label extensions.\nAbstract: Myasthenia gravis (MG) is a rare autoimmune disease characterised by fluctuating and fatigable muscle weakness. In the randomised, double-blind phase III MycarinG study, one 6-week rozanolixizumab cycle significantly improved MG-specific outcomes versus placebo and was generally well tolerated in patients with generalised MG (gMG). To assess the efficacy and safety of cyclic rozanolixizumab treatment. A pooled analysis of the MycarinG, MG0004 and MG0007 studies. Following MycarinG, eligible patients could enrol in the open-label extension studies MG0004 or MG0007 to receive rozanolixizumab 7 or 10\u2009mg/kg. In MG0004, patients received chronic weekly treatment for \u2a7d52\u2009weeks. In MG0007, after an initial 6-week treatment cycle, subsequent cycles were based on symptom worsening (investigator's discretion). Final efficacy data were pooled across MycarinG, MG0004 (first 6\u2009weeks) and MG0007 for patients receiving \u2a7e2 symptom-driven cycles. Efficacy endpoints included change from baseline (CFB) in MG Activities of Daily Living (MG-ADL), MG Composite (MGC) and Quantitative MG (QMG) scores. Safety outcomes were assessed in patients who received \u2a7e1 cycle with a \u2a7d8-week follow-up period across MycarinG and MG0007. Overall, 188 patients received \u2a7e1 cycle and 129 received \u2a7e2 symptom-driven cycles. Across Cycles 1-13, mean (standard deviation) CFB to Day 43 in MG-ADL score ranged from -3.2 (3.3 (n\u2009=\u2009113; Cycle 3)) to -6.0 (3.9 (n\u2009=\u200924; Cycle 12)). Consistent improvements in MGC and QMG scores were also observed across repeated cycles. Treatment-emergent adverse events (TEAEs) were experienced by 175/188 (93.1%) patients; most mild or moderate. Incidence remained stable with repeated cyclic treatment among patients who remained in the study at each cycle. The most common TEAE was headache (n\u2009=\u200994/188 (50.0%)). Repeated rozanolixizumab treatment cycles demonstrated consistent, clinically meaningful improvements in MG-specific outcomes as early as 1\u2009week after the first infusion. Rozanolixizumab was generally well tolerated with an acceptable safety profile, supporting its long-term use as a treatment option for adults with gMG. ClinicalTrials.gov: NCT03971422; NCT04124965; NCT04650854. Long-term treatment with cycles of rozanolixizumab improved symptoms in patients with generalised myasthenia gravis in a combined analysis of final data from the MycarinG study and its two extension studies Generalised myasthenia gravis (gMG) is an autoimmune disease that damages the connections between nerves and muscles, causing muscle weakness. In the MycarinG study, treatment with rozanolixizumab once a week for 6 weeks was better at improving gMG symptoms than placebo in adults with gMG. After MycarinG, patients could enter the extension studies MG0004 and MG0007. These studies assessed the side effects of long-term rozanolixizumab treatment and measured patients\u2019 symptoms to see whether rozanolixizumab remained effective. In MG0004, patients received rozanolixizumab once a week for up to 52 weeks. In MG0007, patients received rozanolixizumab once a week for 6\u2009weeks, termed a treatment cycle. After the first treatment cycle, patients only received more cycles if their symptoms worsened. We looked at data from patients who received repeated rozanolixizumab treatment cycles across MycarinG, MG0004 (first 6 weeks only) and MG0007. Treatment side effects and gMG symptoms were assessed. Overall, 129 patients received two or more rozanolixizumab cycles due to worsening symptoms. We saw consistent improvements in gMG symptoms across multiple measures; improvements were maintained over repeated treatment cycles. Altogether, we assessed 188 patients for side effects; 175 (93.1%) reported a side effect, most of which were mild or moderate in severity. The most common side effect was headache. The number of reported side effects and how bad they were did not change much across treatment cycles among patients who stayed in the study at each cycle. In the first year of treatment, patients had an average of four treatment cycles. Based on this, rozanolixizumab treatment would be expected to follow a repeated pattern of 6\u2009weeks on treatment and 6\u20138\u2009weeks off in the first year. Together, these data suggest that repeated rozanolixizumab cycles can be used for long-term treatment in patients with gMG.\n\nID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

A total of 2,215 thyroid surgeries and 194 autopsies were reviewed, identifying 17 and 1 case of NRLN, respectively. Data regarding nerve anatomy, associated vascular anomalies, and patient medical history were collected and analyzed. Neck ultrasound examinations were subsequently performed on the 17 living patients, 5 months to 19 years post-surgery, by three radiologists specializing in head and neck soft-tissue imaging. Two radiologists were blinded to the specific nerve anatomy, while one was unblinded. Vascular anomalies of the aortic arch were described only by the unblinded radiologist. Among the 17 NRLN cases, three (16.7%) exhibited normal vascular anatomy. According to Toniato et al.'s classification, one case each was categorized as 2a, 2b, and one case involved a coexisting right NRLN and right RLN. No definitive recurrent paresis was observed, with only one patient experiencing transient palsy lasting 5 weeks. Histological evaluation revealed no structural differences between NRLN and RLN variants, although their epineurium and adventitia were notably thinner than those of the vagal nerve. Achieving blood-free conditions for meticulous dissection and preserving sympathetic nerve branches are essential for optimal functional outcomes in thyroid surgeries involving NRLNs.\n\nID: 42379476\nTitle: Exposure to toxic metals/metalloids in the environment and in vitro fertilization outcomes in a population group from Romania.\nAbstract: Globally, the infertility prevalence (both genders) has shown a gradual upward trend, with a 0.5%-0.7% annual rise in infertility rates between 1990 and 2021. An increasing proportion of women in Romania experiencing infertility are resorting to in vitro fertilization (IVF) to achieve pregnancy. Our study included 47 women who completed an IVF cycle at the 1st Obstetrics and Gynecology Clinic (Cluj-Napoca), between April - October 2019, and July - December 2022. All participants completed a questionnaire. We collected data from the participant medical records on antral follicle count, levels of hormones, response to ovarian stimulation, number of retrieved oocytes, thickness of the endometrial mucosa, and IVF endpoints (fertilized oocytes, number and quality of embryos, pregnancy, live births). Urine, blood, ovarian follicular fluid, and endometrial flushing fluid specimens were collected at the time of oocyte retrieval, for metal and genetic analysis. Lead (Pb), arsenic (As) and cadmium (Cd) levels were measured in biological samples collected from our study participants using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) technique. In approximately 19% of the analyzed samples, the total urinary As exceeded the reference value of 15 \u00b5g/L. Also, in 15% of the samples, urinary Cd exceeded the reference value of 2 \u00b5g/L, while the blood Pb levels were below 10 \u00b5g/dl. Our study results indicated no significant differences as regards the IVF outcomes in relation with low-level As, Cd and Pb exposure, whereas higher tobacco smoke exposure, assessed via urinary cotinine, was linked to a lower fertilized oocytes and blastocysts number.\n\nID: 42378334\nTitle: Nationwide trends and forecasts in Alzheimer's and cerebrovascular disease-related mortality in the United States, 1999-2023: A CDC WONDER analysis.\nAbstract: ObjectiveTo describe nationwide mortality patterns related to Alzheimer's disease and cerebrovascular disease in United States adults aged \u226565\u2009years and explore future trend projections.MethodsIn this retrospective study, we utilized the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research database (ICD-10 G30, I60-I69) to calculate crude and age-adjusted mortality rates per 100,000 population. Temporal trends were modeled using Joinpoint regression, and 10-year forecasts were obtained using autoregressive integrated moving average models. Subgroup analyses were performed by sex, race/ethnicity, census region, urbanization, and place of death.ResultsWe identified 199,606 Alzheimer's disease-cardiovascular disease-related deaths. Overall, age-adjusted mortality rates peaked at 24.8 in 2002, reduced to 14.2 in 2013, and then rose to 18.7 in 2020 before dropping to 16.6 in 2023. Women exhibited higher age-adjusted mortality rates than men (20.1 vs. 16.0). Individuals of White and Black ethnicity bore the greatest burden, and the South and West recorded the highest regional age-adjusted mortality rates. These rates were consistently higher in non-metropolitan areas than in metropolitan areas. Exploratory projections estimate an overall age-adjusted mortality rate of 16.6 by 2033, with persistently higher rates in women, non-Hispanic Black populations, and among those residing in the West and non-metropolitan areas.ConclusionsDespite substantial decline since the early 2000s, Alzheimer's disease-cardiovascular disease mortality remains high and unevenly distributed. Exploratory projections suggest that the burden will remain substantial, underscoring the need for targeted prevention, vascular risk reduction, and equity-focused dementia care.\n\nID: 42373582\nTitle: Unravelling the Significance of Cystatin C and Bunina Bodies in Amyotrophic Lateral Sclerosis Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a fatal neurodegenerative disease primarily affecting motor neurons. Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies.\n\nID: 42371281\nTitle: Trends and Disparities in Mortality from Hereditary Ataxia in United States, 2000-2020: A Retrospective Analysis with Projections to 2050.\nAbstract: Hereditary ataxias are rare cerebellar disorders. Population level mortality patterns in the United States in the previous decades remain insufficiently described. We quantified national mortality trends associated with hereditary ataxias and described stratified trends by sex, race, census region, and urbanization. We analyzed U.S. Multiple Cause of Death data from CDC WONDER for 2000 to 2020. Decedents were identified using ICD-10 code G11 for hereditary ataxias. Age-adjusted mortality rates (AAMRs) per 100,000 were computed using the 2000 U.S. standard population, with 95% confidence intervals. Temporal trends were evaluated using joinpoint regression to estimate annual percent change (APC). Forecasts through 2050 were generated using ARIMA, with sensitivity analysis using linear regression. National AAMR increased significantly from 2000 to 2020. Rising rates were observed in both sexes, with consistently higher mortality among males. The largest relative increases occurred among Black or African American individuals and in the West census region. Trends were directionally consistent across urbanization categories, and the forecast analyses also indicated increasing overall mortality. Sensitivity analyses produced qualitatively similar patterns, with wider uncertainty within strata. Mortality associated with hereditary ataxias increased in the United States between 2000 and 2020, highlighting growing clinical and public health needs related to cerebellar disease. Improved phenotyping and coding, earlier diagnosis, and registry-linked surveillance may refine estimates and support service planning.\n\nID: 42370609\nTitle: Catheter ablation of atrial fibrillation in transthyretin and light-chain cardiac amyloidosis: results from the multicentre AMYL-AF study.\nAbstract: Atrial fibrillation (AF) is highly prevalent among cardiac amyloidosis (CA) patients and contributes significantly to their morbidity and mortality. Evidence regarding AF ablation efficacy and safety in CA patients remains limited. The aim of our study is to evaluate baseline characteristics, clinical course and outcomes of AF ablation in a series of patients with transthyretin (ATTR) or light-chain (AL) CA from a multicentre international registry. Patients with CA who underwent AF ablation were included. Co-primary endpoints were: (i) atrial arrhythmia (AA) recurrence; (ii) a composite endpoint of all-cause mortality and heart failure hospitalization (HFH). 109 patients (mean age 72.4 \u00b1 7.4 years, females 17.4%, persistent AF 64.2%, ATTR 78%, AL 22%) were included. Radiofrequency, cryo-balloon and pulsed-field ablation were performed in 67%, 15% and 18% of patients, respectively; 49.5% received pulmonary vein isolation plus additional ablations. Low voltage zones were documented in 34 out of 44 patients undergoing electro-anatomical mapping (77.3%). During a median follow-up of 22.7 months, 63 patients (58.3%) experienced AA recurrence (32.4% persistent AF recurrence), with no significant differences between CA subtypes (ATTR 59.5% vs. AL 54.2%, log-rank P = 0.55). The composite endpoint of HFH and all-cause death occurred in 27 patients (25%). Recurrence of persistent AF was associated with three-fold higher risk (OR 2.9, P = 0.02) of the composite endpoint. CA patients undergoing AF ablation present high prevalence of persistent AF. Freedom from AA after AF ablation is achieved in 42% of patients after a two-year follow-up. Patients with persistent AF recurrence have a three-fold higher risk of HFH and death.\n\nID: 42367369\nTitle: Preparing Amyotrophic Lateral Sclerosis Clinics to Provide Longitudinal Care for Individuals Carrying ALS Risk Variants.\nAbstract: Emerging genetic therapies and the expansion of genetic testing are identifying individuals carrying amyotrophic lateral sclerosis (ALS) risk variants who would benefit from surveillance and early intervention. Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.\n\nID: 42363764\nTitle: RNA G-quadruplexes function as a tunable switch of FUS phase separation.\nAbstract: Fused in sarcoma (FUS) undergoes liquid-liquid phase separation (LLPS) to support essential cellular functions, but aberrant phase transitions promote toxic aggregation in neurodegenerative disease. Short RNA oligonucleotides can reverse this behavior, yet the structural determinants that govern RNA activity remain poorly defined. Here, we identify RNA G-quadruplexes (rG4s) as tunable structural motifs that potently modulate FUS LLPS. rG4 activity depends on its concentration and is modulated by rG4 length and stability: increasing repeat number switches rG4s from inhibitor to nucleator of FUS assembly, whereas chemical modifications that stabilize rG4 enhance inhibitory function and render these activities resilient to ionic perturbation. Although short rG4s interact with both soluble and condensed FUS, they preferentially engage the soluble pool, likely shifting the equilibrium toward dispersion. Leveraging these mechanistic insights, we developed a bioinformatic pipeline that uncovered more rG4 inhibitors that robustly reverse FUS LLPS and aggregation. Our findings establish rG4s as chemically programmable regulators of protein phase behavior and provide a blueprint for engineering RNA-based therapeutics that dissolve pathogenic FUS assemblies. More broadly, this work directly links RNA secondary structure to distinct functional outcomes in phase behavior, establishing a structure-function paradigm for RNA control of condensates, demonstrating implications in both fundamental biology and therapeutic development.\n\nID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.\n\nID: 42361348\nTitle: Remote Assessment of Parkinson Disease Using Deep Learning on Structured Mouse-Trace Data From Suspected Cases: Machine-Learning Pilot Feasibility Study.\nAbstract: Parkinson disease (PD) is a pervasive neurodegenerative disorder globally, largely characterized by motor symptoms. Most existing artificial intelligence models for PD detection are trained on participants in well-resourced settings with confirmed clinical diagnoses. However, specialist-confirmed labels are often infeasible in low-resource settings. We developed a web platform for structured mouse data collection through pattern tracing tests. We sought to assess the feasibility of leveraging data from a community-recruited sample of participants with suspected but undiagnosed PD to train artificial intelligence models that achieve respectable performance in predicting diagnosed PD. We tested whether using weaker diagnostic labels that may be more feasible to collect in community or global health settings, where access to professional neurologists is sparse or nonexistent, can lead to models that learn predictive signals that are diagnostically useful. 261 participants (73 self-reported PD, 155 non-PD, and 33 suspected PD) were recruited from community organizations in Hawaii and completed 3 pattern tracing tasks on our custom web assessment: straight line, sine wave, and spiral wave. During each task, cursor positions, screen dimensions, and an in-target boolean flag were recorded. From these data, we engineered features and generated mouse trace images. We built 3 categories of classifiers: (1) a feed-forward neural network using engineered features, (2) fine-tuned computer vision deep learning models, and (3) multimodal models concatenating a feed-forward neural network with computer vision models. Performance was evaluated using 1 primary experiment and 2 secondary analyses. The primary experiment involved training on suspected PD versus non-PD and testing on self-reported PD versus non-PD. A secondary analysis evaluated the reverse direction by training on participants with self-reported PD and without PD and then testing on participants with suspected PD versus participants without PD. Additionally, a cross-validation analysis was conducted using participants with self-reported PD versus those without PD with 5-fold cross-validation to establish baseline performance under well-defined diagnostic labels. The best-performing models included a multimodal Vision Transformer in the primary experiment (F1: mean 0.7619, SD 0.0535), a multimodal ResNet-50 in the secondary analysis (F1: mean 0.9353, SD 0.0334), and an image-based DenseNet-201 in the cross-validation analysis (F1: mean 0.9027, SD 0.0332). Training on patients with suspected PD yielded meaningful performance in predicting self-reported PD, supporting the feasibility of using lower-specificity labels for model development. This pilot feasibility study suggests that remotely collected mouse-tracing data can support PD screening models under data labeling conditions of low diagnostic specificity: models trained on suspected PD from a community sample may learn signals that can transfer to predicting actual PD. Future work may consider pretraining using weaker labels and then fine-tuning on stronger clinical labels.\n\nID: 42360551\nTitle: Targeting mtDNA to Modulate Mitochondrial Dysfunction in Neurodegenerative Diseases.\nAbstract: Mitochondrial dysfunction is a common pathological feature of neurodegenerative diseases namely Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. Although these disorders are primarily driven by disease-specific genetic and proteopathic mechanisms, increasing evidence suggests that secondary mitochondrial DNA (mtDNA) damage and heteroplasmy shifts may exacerbate bioenergetic failure and neuronal vulnerability. Distinguishing primary disease mechanisms from downstream mtDNA alterations is critical to accurately evaluate emerging therapeutic strategies. Recent advances in mtDNA-targeted genome editing have enabled the direct manipulation of mitochondrial genomes. Mitochondrially targeted zinc finger nucleases and TALENs can selectively alter mutant mtDNA to induce heteroplasmy shifts, whereas DddA-derived cytosine base editors allow precise base editing without double-strand breaks. However, each platform has distinct limitations related to the target scope, off-target risk, design complexity, and delivery efficiency. The application of CRISPR/Cas-based systems to mammalian mtDNA remains constrained by the unresolved challenges in guiding RNA import. This review critically examines mitochondrial dysfunction and mutant\u00a0mtDNA accumulation in neurodegenerative diseases. It also evaluates current and emerging mtDNA-editing techniques, and highlights key translational barriers. We highlighted that mtDNA-targeted interventions can be a promising approach for\u00a0disease-modifying or adjunctive strategies, rather than curative approaches.\n\nID: 42360419\nTitle: [The digital patient journey : Performing radiological examinations].\nAbstract: The rising demand for imaging studies, increasing diagnostic complexity, and limited personnel resources are organizational challenges for radiology departments. Efficient management of the examination process is essential to ensure timely and high-quality patient care. Digital technologies and artificial intelligence (AI)-based systems have the potential to optimize imaging workflows within the examination room. To present digital processes used during radiological examinations and to assess their implications for radiology workflow, personnel structure, and patient care. Current scientific publications and reviews on digital workflows, automated planning, deep learning reconstruction, real-time quality control, and remote scanning concepts in radiological image acquisition were summarized and systematically analyzed. Digital systems enable increased patient comfort, standardized protocol initialization, automated slice planning, deep learning reconstruction, and quality monitoring during image acquisition. These approaches may improve efficiency, and robustness of examinations while reducing the need for repeat scans. Remote scanning provides opportunities for cross-site support and expertise sharing. The digital transformation of radiological examination workflows represents a\u00a0key lever for optimizing clinical processes. Digital and AI-based approaches may enhance efficiency and patient-centered care, but require thorough validation, interoperability, and responsible integration into existing healthcare structures.

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.\n\nID: 42359357\nTitle: Innate immune crosstalk in ALS/FTD pathogenesis.\nAbstract: Marked by protein aggregation, impaired proteostasis, organelle stress, and chronic neuroinflammation, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) form a clinically, genetically, and pathologically overlapping disease spectrum. Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.\n\nID: 42358974\nTitle: Successful rescue therapy with eculizumab for probable tislelizumab-related MMM overlap syndrome with dual positivity for anti-acetylcholine receptor and anti-titin antibodies: a case report and literature review.\nAbstract: While immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, they can trigger diverse immune-related adverse events (irAEs). Among these, ICI-related myocarditis, myositis and myasthenia gravis (MMM) overlap syndrome (ICI-MMM) is a rare but potentially fatal complication. Conventional immunotherapy often exhibits limited efficacy against ICI-MMM, which is associated with high mortality rates. Thus, there is an urgent need for novel and effective strategies to mitigate its life-threatening outcomes. We conducted a retrospective analysis of the successful rescue use of eculizumab in a patient with tislelizumab-related MMM overlap syndrome who tested seropositive for both anti-acetylcholine receptor (AChR) and anti-titin antibodies. We also performed a focused systematic literature review on the use of complement inhibitor therapy for ICI-related myasthenia gravis and its overlap syndrome. A 64-year-old male developed ptosis and tetraparesis two weeks following the second infusion of tislelizumab for lung adenocarcinoma. Serological testing revealed dual positivity for anti-AChR antibody and anti-titin antibody. Tislelizumab was immediately withdrawn, and the patient was treated with corticosteroids and intravenous immunoglobulin as first-line therapy. However, his clinical condition deteriorated rapidly, and new symptoms emerged, including chest pain, muscle pain, dysphagia, slurred speech, and dyspnea. Although the absence of histopathological confirmation for myocarditis and myositis, the clinical, laboratory, electrophysiological, and cardiac imaging findings supported the diagnosis of probable ICI-MMM. Rescue therapy with eculizumab was commenced (900 mg weekly for four doses), eliciting rapid and marked clinical improvement. The patient ultimately achieved minimal symptom expression without any exacerbation. This is the first reported case of successful eculizumab rescue treatment for probable tislelizumab-related MMM overlap syndrome with dual seropositivity. Our finding suggests eculizumab may represent a promising rescue option for ICI-MMM warranting prospective evaluation.\n\nID: 42353839\nTitle: Transthyretin Amyloidosis-From Peculiar Neuropathy to a Treatable Chronic Multisystemic Disease.\nAbstract: Transthyretin amyloidosis (ATTR) is a multisystemic disorder associated with extracellular accumulation of misfolded transthyretin (TTR) protein forming insoluble amyloid deposits. Depending on the TTR genotype, ATTR is classified as hereditary ATTR (ATTRv) with pathogenic gene variants and wild-type ATTR (ATTRwt) with a normal TTR genotype. Two cardinal clinical manifestations of ATTR are amyloid cardiomyopathy and peripheral neuropathy, but multisystemic deposition of amyloid may also manifest with ocular and leptomeningeal amyloidosis, various orthopedic complications (carpal tunnel syndrome, spinal stenosis), nephropathy, and gastrointestinal and pulmonary amyloidosis. The natural history of untreated ATTR is characterized by progressive worsening and 25% of patients may die within 24 months from the onset. The first treatment for ATTR was liver transplantation which slows the disease progression, but its use was limited by the scarcity of available liver allografts and complex post-transplant morbidities associated with immunosuppression and various metabolic disturbances. Recent introduction of TTR stabilizers and gene silencing has significantly changed the outcomes and reduced ATTR-related morbidities and mortality, and early diagnosis remains important for improved outcomes. In our narrative expert review, we are discussing epidemiological and clinical features of ATTR, its pathophysiology and available treatments as rapidly progressive fatal disease is being transformed into a treatable chronic disease.\n\nID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42396333\nTitle: The Target ALS Global Natural History Study: Cross-platform proteomics to accelerate biofluid biomarker and drug target discovery in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal, rapidly progressive neurodegenerative disease of motor neurons for which therapeutics are limited. Improved biomarkers are imperative to improve patient care and therapeutic development. Here, we employed 35-plex isobaric tandem mass tag labeling based on isobutyl-proline reporter group (TMTpro) to perform unbiased proteomic analysis of cerebrospinal fluid (CSF) and plasma from control (n= 28, n= 31) and sporadic ALS (sALS) (n= 39, n= 41), from the Target ALS Global Natural History Study (TALS GNHS). We identified 2,875 proteins in CSF and 1,118 proteins in plasma and identified known and novel differentially expressed proteins (DEPs) between controls and sALS, some of which were orthogonally validated using immunoassay. Comparison of TMTpro-MS and Olink proximity extension assay proteomics revealed common and non-overlapping differentially expressed proteins illustrating strengths unique to each platform. This initial cross-sectional proteomic study of biofluids from the TALS GNHS, with unrestricted availability of study results to the research community, highlights the potential of this resource as a potent platform for ALS biomarker discovery.\n\nID: 42393765\nTitle: Phenotype-specific muscle proteomic profiling in titinopathies.\nAbstract: Titinopathies are complex neuromuscular disorders with multiple phenotypes. The gene's size, comprising 364 exons, as well as the protein's size of 3.8 MDa and its extensive network of protein interactors, are key factors underlying this complexity. Various phenotypes characterize titinopathies, and this study focuses on two of them: arthrogryposis and myofibrillar myopathies. The protein deregulations associated with these two phenotypes remain unknown or have been minimally explored; however, understanding these consequences is essential for better characterizing the pathophysiological aspects of these titinopathies.The objective was to analyze protein deregulations in two cohorts of French patients with titinopathies exhibiting the arthrogryposis and myofibrillar myopathy phenotypes, and to compare them with control individuals. Protein extracts were obtained from muscle biopsies of patients, and changes in protein levels within these two groups were analyzed by mass spectrometry. The results indicate specific deregulations in each group. The networks analyzed revealed deregulation of proteins involved in fibrosis mechanisms or in the actomyosin complex for the arthrogryposis phenotype. Regulation of the muscle contraction system through deregulation of proteins involved in the cytoskeleton is impacted in patients with myofibrillar myopathy. The proteins that are quantitatively abnormal in these two groups also provide insights into the major signaling networks disrupted in titinopathies. These findings will contribute to a more precise characterization of titinopathies, enabling the identification of phenotype-specific biomarkers and potentially guiding the search for targeted therapies for these neuromuscular disorders.\n\nID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.\n\nID: 42381263\nTitle: Longitudinal Dynamics of Polyglutamine-Expanded ATXN3 in Biofluids of Spinocerebellar Ataxia Type 3.\nAbstract: Spinocerebellar ataxia type 3 (SCA3), the most common autosomal dominant ataxia, is driven by the accumulation of polyglutamine-expanded (polyQ) ATXN3 proteins. While promising as biomarkers, their longitudinal trajectories across multiple biofluids remain poorly defined. To quantify polyQ ATXN3 levels in cerebrospinal fluid (CSF), plasma, and urine within a comprehensive cohort, utilizing serial measurements to map protein dynamics. We employed a validated immunoassay to quantify polyQ ATXN3 in 97 symptomatic and 13 presymptomatic SCA3 patients, correlating levels with clinical features, ancestry, disease status, and longitudinal progression. Asian participants exhibited lower plasma but elevated urinary polyQ ATXN3 levels relative to other ancestries. While CSF levels were higher in symptomatic patients at baseline, they showed a significant longitudinal decline. PolyQ ATXN3 is a viable multi-biofluid biomarker. Declining CSF levels likely reflect neurodegeneration, supporting its role in tracking progression and emphasizing the need for ancestry-based adjustment in trials. \u00a9 2026 International Parkinson and Movement Disorder Society.\n\nID: 42378369\nTitle: RETRACTED: Kim et al.

To isolate and identify Candida spp. from oral swabs of domestic cats. Detection of virulence factors, agglutinin-like sequence agglutinin-like sequence 1 (ALS), and Candidalysin (ECE1) genes exploration of the possible relationship between Candida and potential risk factors in cat owners. A total of 119 oral swabs were collected from cat owners and streaked directly on Sabouraud's dextrose and chrome agars. Confirmation was performed by testing the isolates using the Vitek 2 compact system and conventional polymerase chain reaction (PCR) using primers specific to the ITS4 and ITS5 regions. ALS and ECE1 genes were detected using conventional PCR. The total number of Candida spp. isolated from the oral cavity of cat owners was 10/119 (8.40%). Correlations were reported between the isolation of Candida from the oral cavity and age group; use of oral antibiotic drops; diabetes mellitus; oral lesions; and vitamin D3 deficiency (p value < 0.001). No significant correlation was reported between sex, season, smoking habit, denture wearing, steroid inhalation, immune suppression, and Candida isolation from the oral cavity of cat owners. ASL1 and ECE1 were detected in 100% of C. albicans isolated from the oral cavity of cat owners. This study reveals a low prevalence but high pathogenic potential of oral C. albicans in domestic cat owners, as evidenced by the universal presence of major virulence genes (ALS1, ECE1). Older age, antibiotic drops, Diabetes miletus, oral lesions, and vitamin D3 deficiency were associated with the risk of colonization. The commonly suspected risk factors showed no association. The universal presence of ALS1 and ECE1 highlights the pathogenic threat posed by these yeasts.\n\nID: 42371053\nTitle: Neurodegenerative diseases and environmental risk factors: an overview of the available scientific evidence.\nAbstract: Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) are among the most well-known and prevalent neurodegenerative disorders. These diseases result from an interaction between the environment and genetically predisposed individuals. This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf.\n\nID: 42369360\nTitle: Assessing upper motor neuron dysfunction in ALS: from TMS-EEG and EMG neurophysiology to a combined tFUS-TMS translational framework.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder characterized by the progressive loss of upper motor neurons (UMNs) and lower motor neurons (LMNs). Despite significant advances in molecular and neuroimaging biomarkers, the initial site of pathology and the causal contribution of UMN dysfunction to disease progression remain undetermined. Accumulating neurophysiological evidence points to cortical hyperexcitability as an early and potentially upstream mechanism, raising the possibility that UMN pathology drives LMN degeneration through an anterograde dying-forward process. In this review, we synthesize findings from noninvasive brain stimulation (NIBS) studies, with particular emphasis on transcranial magnetic stimulation (TMS)-based neurophysiological markers of UMN dysfunction. We review evidence from TMS-electromyography (TMS-EMG) and TMS-electroencephalography (TMS-EEG) paradigms demonstrating cortical disinhibition and excitatory-inhibitory imbalance in ALS, consistent with impaired GABAergic interneuronal dysfunction and supportive of a cortical onset hypothesis. Finally, we propose integrating transcranial focused ultrasound (tFUS) with TMS as a novel experimental and translational framework to directly examine and modulate cortical hyperexcitability and test the causal role of UMN dysfunction in ALS. The combination of targeted neuromodulation with sensitive neurophysiological readouts in controlled experimental designs offers a promising avenue to advance mechanistic insight, refine biomarkers, and inform mechanism-based therapeutic strategies. Together, these approaches position noninvasive neurophysiology as a powerful tool for elucidating UMN dysfunction in ALS.\n\nID: 42368206\nTitle: Editorial: Neuromuscular disorders: biomarkers, precision diagnosis, and targeted therapeutics.\nAbstract: \n\nID: 42360421\nTitle: [Prevention instead of remediation-screening, lifestyle factors, and prostate care\u00a02.0-transition of urology to healthcare coach : Holistic approach to prostate health].\nAbstract: Establishment of an organized, risk-adapted prostate cancer screening program in Germany could serve as a\u00a0key entry point for preventive men's health. How can the introduction of an organized, risk-adapted prostate cancer screening program in Germany shape preventive urology of the future? This narrative review article is based on guidelines and expert consensus supported by a\u00a0literature search in PubMed. The cited studies represent the most relevant work on this topic and were selected to illustrate developments and fundamental concepts; however, completeness is not claimed. Serum prostate-specific antigen (PSA) levels and prostate MRI not only identify patients at increased risk for prostate cancer but also offer insights into other urological conditions, such as lower urinary tract symptoms and hypogonadism. In analogy to other early detection strategies, PSA testing at the age of 45-50\u00a0years could serve as a\u00a0simple triage test to guide risk-adapted follow-up and timely referral to urological care. Lifestyle factors-including regular physical activity, a\u00a0balanced diet, and pelvic floor training-may favorably influence urological health and related outcomes. While organized prostate cancer screening has already been shown to improve cancer-specific mortality to a\u00a0level comparable to mammography, a\u00a0more holistic approach may further enhance its overall benefit. Urology has significant opportunities to actively promote healthy behaviors among aging men. The establishment of an organized prostate cancer screening program provides an ideal entry point for this purpose. Modern screening concepts should incorporate holistic health promotion for aging men alongside direct oncological endpoints.

Dieser narrative \u00dcbersichtsartikel auf der Grundlage von Leitlinien und Expertenkonsens wird unterst\u00fctzt durch eine Literaturrecherche auf PubMed (2000\u20132026). Die zitierten Studien stellen nach Meinung der Autoren die relevanten Arbeiten hierzu dar und wurden ausgew\u00e4hlt, um Entwicklungen und prinzipielle Konzepte zu veranschaulichen, beanspruchen jedoch keine Vollst\u00e4ndigkeit. Der PSA-Wert (prostataspezifisches Antigen) und die MRT liefern nicht nur Hinweise auf ein Prostatakarzinom, sondern auch auf andere urologische Erkrankungen wie Miktionsbeschwerden oder Testosteronmangel. Parallel zu anderen Fr\u00fcherkennungsuntersuchungen k\u00f6nnte der PSA-Wert mit 45\u201350\u00a0Jahren als einfaches Triage-Tool fungieren, um risikoadaptierte Verlaufskontrollen sowie fachurologische Vorstellungen zu steuern.

Autonomic disturbances, particularly cardiac dysautonomia, significantly impact patient outcomes, contributing to increased cardiovascular risks and mortality rate. While the ALS Functional Rating Score-Revised (ALSFRS-R) measures functional decline as disease progress, it overlooks autonomic criteria - a critical factor in ALS progression. This review aims to analyze noninvasive applications of cardiovascular signal variability for continuous real-time monitoring of autonomic dysfunction in ALS, while addressing gaps in current clinical assessments. A total of 584 literatures were gathered from four databases (WoS, PubMed, Science Direct and MEDLINE EBSCOhost) - published from inception till December 2023. 21 peer-reviewed studies were included in this review after screening and meeting the inclusion criteria. Various cardiovascular signal variability metrics and autonomic protocols were discussed. Key findings highlight cardiac autonomic dysfunction in ALS is marked by reduced heart rate variability, absent blood pressure regulation upon orthostatic stress and circadian changes, prolonged QTc interval and low baroreflex sensitivity. Moreover, increased autonomic burden is associated with a shift from sympathetic to parasympathetic dysregulation as the disease progresses. Evidence highlights the need to integrate noninvasive autonomic biomarkers into digital ALS monitoring frameworks, enabling earlier detection of autonomic involvement and more precise longitudinal monitoring beyond motor decline.\n\nID: 42359392\nTitle: Nonlinear combinatorial analysis of blood transcriptomes identifies PRKAR1A as a regulator of TDP-43 pathophysiology in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive loss of motor neurons. Accurate and accessible blood-based diagnostics for neurodegenerative diseases, including ALS, are being progressively required. Although blood cell gene expression profiles have potential clinical utility for distinguishing ALS, robust transcriptomic biomarkers for supportive diagnosis have not yet been established. Here, we analyzed publicly available peripheral blood mononuclear cell (PBMC) transcriptomic data from ALS patients using Maximum Mean Discrepancy, a kernel-based method that captures nonlinear distributional differences in a reproducing kernel Hilbert space and enables the extraction of informative gene combinations while minimizing multicollinearity, a common issue in multiple regression models. Using this approach, we identified a nonlinear three-gene combination-PRKAR1A, QPCT, and TMEM71-that distinguished ALS from healthy controls with an area under the curve (AUC) of 0.83 in a public PBMC dataset. This achievement was confirmed in laboratory PBMC samples with an AUC of 0.85, supporting the robustness of the identified gene signature in independent samples. Furthermore, these genes also enabled ALS classification in induced pluripotent stem cell-derived motor neurons with an AUC of 0.79. Knockdown of PRKAR1A, QPCT, or TMEM71 in motor neurons increased the TDP-43 expression levels, and PRKAR1A knockdown induced the mislocalization of TDP-43, accompanied by phosphorylation, suggesting a potential link to ALS-related pathophysiology. These findings suggest that nonlinear gene combinations may provide a useful strategy for identifying blood-based biomarkers and offer insights into ALS pathogenesis. This nonlinear, data-driven analytical framework enabled the transition from unbiased gene discovery to the identification of pathophysiology-associated molecules by in vitro functional validation.\n\nID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown. Together, these findings provided important insights into disease mechanisms and potential avenues for improved clinical management.\n\nID: 42347565\nTitle: Quantitative Neuromuscular MRI in CIDP Patients: Interest of a Multiparametric Approach.\nAbstract: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is characterized by heterogeneous clinical presentations and the absence of validated imaging biomarkers. Although several quantitative MRI (qMRI) parameters have been investigated individually, their respective diagnostic and clinical relevance remains unclear. Twenty-eight CIDP patients (21 typical, 7 multifocal) were prospectively enrolled and compared with 13 age- and sex-matched healthy controls and 17 patients with symptomatic hereditary transthyretin amyloid neuropathy (vATTR). All participants underwent 1.5\u2009T qMRI of the sciatic and tibial nerves and of the thigh and leg muscles. Nerve and muscle volume, magnetization transfer ratio (MTR), fat fraction (FF), and T2 relaxation time were extracted. Clinical assessment included ONLS, RODS, and MRC sum score, while electrophysiological evaluation included fibular compound motor action potentials and tibialis anterior MUNIX. Imaging parameters were compared between groups and correlated with clinical and neurophysiological measures. CIDP patients showed significant differences compared with controls in both nerve and muscle metrics. Nerve volume was increased and MTR decreased at both sciatic and tibial levels (p\u2009<\u20090.005). At the muscle level, leg muscles showed increased fat fraction and decreased MTR, while T2 values and muscle volume did not differ significantly. MTR showed the strongest correlations with disability scores and MUNIX. Compared with vATTR patients, CIDP patients had lower sciatic nerve MTR, whereas vATTR patients exhibited larger nerve volumes and more pronounced muscle abnormalities. Nerve volume appears to be a sensitive diagnostic marker, while MTR may reflect disease burden. A multiparametric qMRI approach may improve diagnosis and monitoring in CIDP.\n\nID: 42338888\nTitle: Interplay between B vitamins, fiber, and Bacteroides abundance: a predictive model for anxiety and depression in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and incurable neurodegenerative disease that not only affects motor function but is also associated with gastrointestinal and emotional disturbances. Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.\n\nID: 42331015\nTitle: Malnutrition as a Risk Factor for Cerebral and Glaucomatous Neurodegeneration - Mechanisms and Therapeutic Strategies.\nAbstract: BACKGROUND: Neurodegenerative diseases are an increasing challenge for healthcare systems in the context of demographic change. They affect the central nervous system, including the brain-manifesting, for example, as dementia-as well as the retina, as seen in glaucoma or age-related macular degeneration. Malnutrition-defined as quantitative or qualitative under- or overnutrition-affects key mechanisms that contribute to neuronal and retinal neurodegeneration. OBJECTIVE: The aim of this study is to systematically present the pathophysiological mechanisms of malnutrition-related neurodegeneration, to evaluate the current evidence on dietary patterns and cognitive health, and to derive practical clinical strategies for nutritional optimization. METHODS: Narrative literature review based on peer-reviewed publications from the fields of nutritional medicine, geriatrics, neurology, ophthalmology, and public health. RESULTS: Malnutrition promotes oxidative stress, mitochondrial dysfunction, chronic neuroinflammation, and vascular dysregulation, and it influences neurotransmitter synthesis. These mechanisms are relevant to both cerebral and ocular neurodegenerative processes. The Mediterranean diet and the MIND diet are associated with a significantly reduced risk of cognitive impairment; for ocular diseases, interventional studies in age-related macular degeneration in particular demonstrate protective effects of antioxidant supplementation, whereas evidence for glaucoma is currently based predominantly on observational data. Screening approaches and micronutrient diagnostics enable early identification of at-risk individuals. Building on this, individualised dietary interventions and targeted supplementation of selected nutrients could be potentially preventive and stabilising therapeutic strategies. CONCLUSION: Malnutrition is a key modifiable risk factor for neurodegenerative diseases of the brain and retina. More intense integration of nutritional diagnostics and therapy into neurological, geriatric, and ophthalmological care structures appears warranted.

Fehlern\u00e4hrung f\u00f6rdert oxidativen Stress, mitochondriale Dysfunktion, chronische Neuroinflammation sowie vaskul\u00e4re Dysregulation und beeinflusst die Neurotransmittersynthese. Diese Mechanismen sind sowohl f\u00fcr zerebrale als auch f\u00fcr okul\u00e4re Neurodegenerationsprozesse relevant. Mediterrane Ern\u00e4hrung und MIND-Di\u00e4t sind mit einem signifikant reduzierten Risiko kognitiver Beeintr\u00e4chtigung assoziiert; f\u00fcr okul\u00e4re Erkrankungen zeigen insbesondere Interventionsstudien bei AMD protektive Effekte antioxidativer Supplementierung, w\u00e4hrend f\u00fcr das Glaukom bislang vorwiegend beobachtende Daten vorliegen. Screening-Ans\u00e4tze und Mikron\u00e4hrstoffdiagnostik erm\u00f6glichen die fr\u00fchzeitige Identifikation von Risikopersonen. Darauf aufbauend stellen individualisierte di\u00e4tetische Ma\u00dfnahmen sowie die gezielte Supplementierung ausgew\u00e4hlter N\u00e4hrstoffe potenziell pr\u00e4ventive und stabilisierende therapeutische Strategien dar. Fehlern\u00e4hrung ist ein zentraler, modifizierbarer Risikofaktor neurodegenerativer Erkrankungen des Gehirns und der Retina. Eine st\u00e4rkere Integration ern\u00e4hrungsmedizinischer Diagnostik und Therapie in neurologischen, geriatrischen und ophthalmologischen Versorgungsstrukturen erscheint sinnvoll.\n\nID: 42330948\nTitle: NERINE reveals rare variant associations in gene networks across phenotypes and implicates an SNCA-PRL-LRRK2 subnetwork in Parkinson's disease.\nAbstract: Studying the genetic basis of human phenotypes involves two primary strategies. Model-system experiments generate interpretable gene networks but do not establish relevance to human disease. In contrast, statistical genetics identifies variant- and gene-level associations but cannot test mechanistic models. Here, we bridge these approaches by introducing NERINE, a hierarchical model-based rare variant association test that incorporates gene network topology while remaining robust to network inaccuracies. NERINE supports analysis of networks from established pathway databases and model-system screens. A comprehensive search across pathway databases reveals associations for breast cancer, cardiovascular diseases, and type 2 diabetes not detected by single-gene tests. Applied to experimental screen-derived networks in Parkinson's disease (PD), NERINE highlights autophagy-, vesicle-trafficking-, and protein-homeostasis-related gene modules. Genome-scale CRISPR interference (CRISPRi) screening in human neurons and NERINE converge on PRL, revealing an intraneuronal \u03b1-synuclein/prolactin stress response that may impact resilience to PD.\n\nID: 42329964\nTitle: Applications of electromyography in Amyotrophic Lateral Sclerosis: A systematic review.\nAbstract: This systematic review examined the use of surface electromyography (sEMG) for the neuromuscular assessment of individuals with Amyotrophic Lateral Sclerosis (ALS), focusing on clinical parameters, the muscle groups evaluated, acquisition protocols, technical properties of the recording systems, integration with other technologies, and signal processing strategies. We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential.\n\nID: 42318821\nTitle: 3D-printed lab-on-chip platforms for the detection of neurodegenerative diseases: opportunities and challenges.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's, Parkinson's, and ALS remain some of the most challenging disorders to diagnose at an early stage. Conventional approaches rely on costly neuroimaging or invasive cerebrospinal fluid sampling, which limit accessibility and early intervention. Recent advances in 3D printing have enabled rapid prototyping of lab-on-chip (LOC) platforms that integrate microfluidics, biosensors, and biological models to detect disease-specific biomarkers with high sensitivity and throughput. Herein, we explore the synergistic role of 3D printing technologies and biomaterials in fabricating LOC systems for NDs. We highlight key biomarkers, and neuron- and organoid-on-chip platforms, and discuss the challenges and opportunities in clinical translation. By combining technical innovation in additive manufacturing with biological relevance, 3D-printed LOC devices represent a transformative approach toward precision diagnostics in neuro-medicine.\n\nID: 42311464\nTitle: GLP-1 Receptor Agonists in Neurological Disorders: From Mechanisms to Clinical Translation.\nAbstract: Glucagon-like peptide-1 receptor agonists, or GLP-1RAs, have been used for years to treat type 2 diabetes and obesity. More recently, it has become clear that these receptors are widely distributed throughout the central nervous system (CNS), which has raised the possibility of repurposing these drugs for neurological disorders. In this review we go through the evidence across a range of neurological conditions, discuss the main mechanisms thought to explain their neuroprotective effects, and point out the hurdles that still need to be cleared before they can be used in the clinic. Preclinical work has been fairly consistent. These drugs activate the cAMP/PKA/CREB pathway to boost BDNF expression. They also turn on the PI3K/Akt pathway, which reins in GSK-3\u03b2 and cuts down tau hyperphosphorylation. At the same time, they put the brakes on NLRP3 inflammasome activation in microglia and get AMPK dependent mitochondrial biogenesis and autophagy going. In animal models of Alzheimer's disease (AD), Parkinson's disease (PD), ischemic stroke, intracerebral hemorrhage (ICH), Huntington's disease (HD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), depression, epilepsy, and spinal cord injury (SCI), these cellular changes add up to less protein aggregation, less neuron loss, and better functional outcomes. Clinical data are harder to interpret. Some trials have shown modest improvements in cognition or motor function, but others have found no meaningful effect on disease progression. One thing that does not get enough attention is that different GLP-1 receptor agonists cross the blood-brain barrier at widely varying rates, and these differences could well explain why trial results have been so mixed. Looking ahead, getting these drugs into the clinic will depend on choosing the ones that actually reach the CNS, developing biomarkers that can predict who will respond, and designing trials that take disease heterogeneity into account. Seen this way, this review offers a practical framework for turning mechanistic insights into real patient benefit.\n\nID: 42310783\nTitle: Unpacking weight management interventions measuring eating disorder risk in adults: coding of components of interventions in a systematic review.\nAbstract: Adult weight management interventions are complex; better understanding of the intervention components that may impact eating disorder (ED) risk is required. Weight management randomized controlled trials (RCTs) for adults with overweight/obesity that measured ED risk were systematically searched in four databases and two trial registries. A project-specific codebook was used to code 84 delivery features and 89 intervention strategies of trials. Individual strategies were grouped into 20 clusters which were further grouped into five broad categories. Trial investigators verified coding and narrative synthesis using descriptive statistics of findings was reported. Of 14,880 identified, 58 eligible trials were coded, of which 26 trials with 64 intervention arms were verified and therefore included. Intervention arms included a mean (SD) of 24 (11) intervention strategies. Commonly used intervention strategy clusters were nutrition education (91%), dietary behavior change strategies (84%), physical activity education (81%), and dietary self-monitoring (80%). Few interventions used strategies in the category of psychological components (13-41%). The median (range) intervention duration was 27 (4-104) weeks, and contacts with participants typically included a staged approach of weekly to monthly contact. Adult weight management interventions are multifactorial with varying delivery features and intervention strategies. Despite this, psychological (e.g. weight stigma) and sleep-health related strategies are either rarely used or are underreported. Breaking down intervention components using our framework can help identify which strategies influence outcomes, including eating disorder risk, and inform the design and reporting of future interventions. Some adults seeking weight management for obesity may have an eating disorder or disordered eating behaviors. Research shows most people who take part in behavioral weight management programs have an improvement in eating disorder symptoms, however a small number may experience worsening symptoms. In this study, we break down behavioral weight management programs that measure eating disorder risk to better understand the features they use. We found that these programs vary widely in the number and type of strategies they use, as well as in how they are delivered, such as the length of the program. Strategies that focus on psychological factors (for example, addressing weight stigma) and sleep health were rarely used or reported. These findings are useful in guiding the design and reporting of future behavioral weight management programs. They can also be used in future research to determine which specific program features improve or worsen outcomes such as eating disorder risk.\n\nID: 42304913\nTitle: Nicotine Versus Non-Nicotine Constituents in Neurodegenerative Risk: Evidence from Multivariable Mendelian Randomization.\nAbstract: Nicotine has complex neuropharmacological actions through nicotinic acetylcholine receptors, but its independent role in neurodegenerative diseases remains unclear because tobacco smoke contains many non-nicotine toxicants. This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50). Exposure to nicotine can increase the risks of AD, while conferring protective effects against tremor and EC. Furthermore, exposure to non-nicotine tobacco constituents acts as a risk factor for the incidence of EC.\n\nID: 42304076\nTitle: Multi-omic analysis of deep learning-derived phenotypes links ophthalmic imaging to cardiovascular and neurological traits.\nAbstract: The eye is a recognized source of biomarkers for cardiovascular and neurodegenerative disease risk. Here we characterize the breadth of these associations and identify biological axes that may mediate them. Using UK Biobank data, we developed a multi-omic analysis pipeline integrating physiological, radiomic, metabolomic and genomic information. We trained retinal adversarial autoencoders to represent optical coherence tomography images and color fundus photographs as 256-dimensional embeddings. Retinal adversarial autoencoder-derived embeddings were associated with a range of cardiovascular and neurodegenerative diseases, including ischemic heart disease, cerebrovascular disease, Parkinson's disease and dementia. Examining associations across diverse omics datasets, we provide evidence linking ophthalmic imaging features to neurological and cardiovascular anatomy and function, lipid metabolism and gene sets associated with neurodegenerative pathology. Collectively, our findings show that ophthalmic features reflect complex, multisystem biological processes and reinforce the role of the eye as a composite indicator of systemic health.\n\nID: 42298083\nTitle: The lung-brain axis in neurodegeneration: inflammatory, immune, and vascular mechanisms with therapeutic implications.\nAbstract: Neurodegenerative and chronic pulmonary diseases represent major global health challenges and have widely been investigated separately. Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.\n\nID: 42296997\nTitle: Basal Ganglia and Thalamic Volumes as MRI Markers of Motor and Cognitive Dysfunction in Parkinson's Disease.\nAbstract: To investigate volumetric alterations of the basal ganglia and thalamus in patients with Parkinson's disease (PD) and to evaluate the relationships between regional brain volumes, motor symptom severity, and cognitive performance. 60 patients with PD (20 females, 40 males) and 51 age-matched healthy control participants (26 females, 25 males) were included. Patients with PD were classified according to initial motor phenotype (tremor-dominant vs. bradykinetic-rigid) and cognitive status based on Mini-Mental State Examination (MMSE) scores (21-26 indicating cognitive impairment; \u226527 indicating normal cognition). High-resolution three-dimensional T1-weighted SPGR MRI data were analyzed using the VolBrain automated segmentation pipeline to obtain volumetric measurements of the putamen, caudate nucleus, globus pallidus, and thalamus. All volumetric measures were normalized to total intracranial volume (TIV). Associations between regional brain volumes and Unified Parkinson's Disease Rating Scale (UPDRS) sub-scores were assessed. The mean age of the PD group was 61.2 \u00b1 11.2 years, compared with 60.4 \u00b1 12.0 years in the control group. Right (p = 0.001), left (p = 0.002), and total (p = 0.004) putamen volumes were significantly reduced in patients with PD relative to controls. No significant differences were observed in thalamic volumes between groups (p > 0.05). Within the PD cohort, individuals with MMSE-defined cognitive impairment exhibited significantly smaller thalamic volumes than cognitively normal patients (right: p = 0.002; left: p = 0.001; total: p = 0.001). UPDRS-III scores showed significant negative correlations with putamen volumes (right: r = -0.42, p = 0.001; left: r = -0.43, p = 0.001; total: r = -0.42, p = 0.001), while UPDRS-I scores were negatively correlated with thalamic volumes (right: r = -0.31, p = 0.016; left: r = -0.29, p = 0.041; total: r = -0.30, p = 0.015). Putamen volume reduction is associated with motor dysfunction in PD, whereas thalamic volumetric changes are more closely related to cognitive impairment. TIV-normalized automated MRI volumetry may provide complementary neuroimaging biomarkers for assessing disease severity and monitoring clinical progression. \u00b7 Basal ganglia and thalamic volumes show distinct patterns in Parkinson's disease.. \u00b7 Putamen volume reduction is associated with motor symptom severity.. \u00b7 Thalamic volume changes are associated with cognitive impairment in PD.. \u00b7 TIV-normalized VolBrain-based volumetric MRI analysis may support clinical disease assessment.. \u00b7 Y\u0131ld\u0131z H, Atalay B, \u00f6zdilek b. Basal Ganglia and Thalamic Volumes as MRI Markers of Motor and Cognitive Dysfunction in Parkinson's Disease. Rofo 2026; DOI 10.1055/a-2871-1475. Untersuchung volumetrischer Ver\u00e4nderungen der Basalganglien und des Thalamus bei Patienten mit Morbus Parkinson sowie Bewertung der Zusammenh\u00e4nge zwischen regionalen Hirnvolumina, dem Schweregrad der motorischen Symptome und der kognitiven Leistungsf\u00e4higkeit.Es wurden 60 Patienten mit Parkinson (20 Frauen, 40 M\u00e4nner) und 51 altersgleiche gesunde Kontrollteilnehmer (26 Frauen, 25 M\u00e4nner) in die Studie aufgenommen. Die Parkinson-Patienten wurden nach ihrem initialen motorischen Ph\u00e4notyp (tremordominant vs. bradykinetisch-rigid) und ihrem kognitiven Status basierend auf den Ergebnissen der Mini- Mental State Examination (MMSE) (21\u201326 Punkte: kognitive Beeintr\u00e4chtigung; \u2265 27 Punkte: normale kognitive Leistung) klassifiziert. Hochaufl\u00f6sende dreidimensionale T1-gewichtete SPGR-MRT-Daten wurden mithilfe der automatisierten Segmentierungspipeline VolBrain analysiert, um volumetrische Messungen des Putamens, des Nucleus caudatus, des Globus pallidus und des Thalamus zu erhalten. Alle volumetrischen Messwerte wurden auf das gesamte intrakranielle Volumen (TIV) normalisiert. Es wurden Korrelationen zwischen den regionalen Hirnvolumina und den Subscores der Unified Parkinson\u2019s Disease Rating Scale (UPDRS) untersucht.Das Durchschnittsalter der Gruppe mit Parkinson betrug 61,2 \u00b1 11,2 Jahre, im Vergleich zu 60,4 \u00b1 12,0 Jahre in der Kontrollgruppe. Das Volumina des rechten (p=0,001), linken (p=0,002) und des gesamten (p=0,004) Putamens war bei Parkinson-Patienten im Vergleich zur Kontrollgruppe signifikant reduziert. Es wurden keine signifikanten Unterschiede im Thalamusvolumen zwischen den Gruppen beobachtet (p>0,05). Innerhalb der Parkinson-Kohorte wiesen Personen mit einer gem\u00e4\u00df MMSE definierten kognitiven Beeintr\u00e4chtigung signifikant geringere Thalamusvolumina auf als kognitiv unbeeintr\u00e4chtigte Patienten (rechts: p=0,002; links: p=0,001; insgesamt: p=0,001). Die UPDRS-III-Scores zeigten signifikante negative Korrelationen mit dem Putamenvolumen (rechts: r=\u20130,42; p=0,001; links: r=\u20130,43; p=0,001; gesamt: r=\u20130,42; p=0,001), w\u00e4hrend die UPDRS-I-Scores negativ mit dem Thalamusvolumen korrelierten (rechts: r=\u20130,31; p=0,016; links: r=\u20130,29; p=0,041; gesamt: r=\u20130,30; p=0,015).Eine Verringerung des Putamenvolumens ist bei der Parkinson-Krankheit mit motorischen Funktionsst\u00f6rungen assoziiert, w\u00e4hrend thalamische Volumen\u00e4nderungen enger mit kognitiven Beeintr\u00e4chtigungen zusammenh\u00e4ngen.

We aimed to investigate its temporal pattern and clinical value in two German AIS cohorts.\u00a0Using immunoassay, we measured sGFAP concentrations in 952 samples of 572 AIS patient and 32 samples of controls recruited in Halle [AIS n\u2009=\u2009102, age: 70.9 (\u00b1\u200915.9) years, 52.0% males; controls n\u2009=\u200932, age: 47.6 (\u00b1\u200918.8) years, 59.4% males] and W\u00fcrzburg [AIS n\u2009=\u2009470, age 74.6 (\u00b1\u200912.8) years, 48.3% males]. In AIS patients, we stratified samples according to the time from symptom onset to blood sampling, namely at D1 (<\u200924\u00a0h), D2 (24-48\u00a0h), D3 (48-72\u00a0h) and D5-7 (96-144\u00a0h), and tested associations between biomarker levels and clinical data.\u00a0sGFAP level was increased at all timepoints after AIS compared to control subjects (p\u2009<\u20090.001, age-adjusted p\u2009<\u20090.01) with significant changes over time (D1\u2009<\u2009D2< D3\u2009\u2265\u2009D5-7). We found increased sGFAP concentrations in AIS patients who had altered mental status on admission (p\u2009<\u20090.01), hemorrhagic transformation of AIS (HT, p\u2009<\u20090.001) as well as systemic infections such as pneumonia (p\u2009<\u20090.001). Higher D1 sGFAP concentrations were associated with higher likelihood of modified Rankin Scale\u2009>\u20092 at 3 months [aOR\u2009=\u20091.015 (95%CI\u2009=\u20091.005-1.025), p\u2009=\u20090.004] and a shorter survival at longest follow-up (median: 576 days, max 922 days) [highest tertile vs. lowest tertile HR\u2009=\u20092.94 (95%CI\u2009=\u20091.21-7.17), p\u2009=\u20090.018].\u00a0sGFAP is elevated after AIS and of informative value regarding the risk HT and infections, as well as on the clinical outcome at follow-up.\n\nID: 42290559\nTitle: Integrated Analysis of hsa-miR-26b-5p and hsa-miR-186-5p in Blood Serum and Tumor Tissue Reveals their Prognostic and Predictive Significance in Breast Cancer.\nAbstract: Breast cancer (BC) heterogeneity signifi antly complicates diagnosis, prognosis, and prediction of treatment response. MicroRNAs (miRNAs) have emerged as promising biomarkers due to their involvement in tu- mor progression and in regulating therapy sensitivity. however, the combined clinical signifi ance of circulating and tumor-associated miRNAs, such as hsa-miR-26b-5p and hsa-miR-186-5p, remains insuffi\u00a0\u00a0 \u00a0tly elucidated. Materi- als and Methods. Expression levels of hsa-miR-26b-5p and hsa-miR-186-5p were analyzed in serum and tumor tis- sue of 124 BC patients. Associations with clinicopathological parameters were assessed. The prognostic signifi ance was evaluated based on disease progression and recurrence within 3 years. The predictive value was determined in patients receiving neoadjuvant chemotherapy (4AC regimen) using response assessment and ROC analysis. Re- sults. young BC patients (\u226445 years) demonstrated signifi antly lower circulating levels of both miRNAs. Serum hsa-miR-186-5p expression was associated with early-stage disease, tumor size, lymph node status, and molecular subtype. Increased circulating hsa-miR-26b-5p levels were linked to disease progression, whereas decreased hsa- miR-186-5p levels were observed in patients with unfavorable outcomes. In tumor tissue, hsa-miR-26b-5p expres- sion correlated with tumor grade, size, and metastatic status, showing elevated levels in poorly differentiated tumors and reduced expression in metastatic disease. In contrast, hsa-miR-186-5p was associated with the molecular sub- type and lymph node involvement, with the highest expression observed in hER2-positive tumors and in patients with recurrence. Elevated levels of hsa-miR-186-5p in both serum and tumor tissue were associated with reduced sensitivity to doxorubicin-based neoadjuvant chemotherapy. ROC analysis confi med its predictive value (AUC = \u00a00.750 for serum and 0.818 for tumor tissue). No signifi ant association between hsa-miR-26b-5p and chemothe- rapy response was observed. hsa-miR-26b-5p and hsa-miR-186-5p demonstrate complementary roles in BC biology. hsa-miR-26b-5p is primarily associated with tumor aggressiveness and cancer progression, whereas hsa-miR-186-5p refl cts its molecular characteristics and response to chemotherapy. Their combined assessment in serum and tumor tissue represents a promising approach for improving prognostic stratifi ation and predicting treatment effi acy in BC patients.\n\nID: 42275159\nTitle: Fatty acid amide hydrolase inhibition for treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease caused by the selective loss of upper and lower motor neurons. There is a considerable variability in the disease progression of sporadic ALS, but the molecular basis for phenotypic heterogeneity remains largely unknown. ALS patients often manifest systemic metabolic abnormalities such as glucose intolerance and hypermetabolic state. We conducted reverse translational research to explore therapeutic targets in ALS based on the systemic metabolic alterations in patients and identified several metabolites associated with the disease progression, including metabolites involved in the expanded endocannabinoid system (ECS). In particular, the levels of N-acyl taurines (NATs) were correlated with the longitudinal change in the revised ALS functional rating scale and survival. Experiments with ALS cellular models, iPS cells derived from ALS patients and SOD1G93A transgenic mice revealed that PF-04457845, a fatty acid amide hydrolase inhibitor, upregulated the expanded ECS, particularly the levels of NATs and ameliorated motor neuron degeneration through the regulation of microglial environment, synapse plasticity, and neuronal development. These results collectively indicate that dysregulation of NATs is associated with ALS progression and PF-04457845 may represent a potential disease-modifying therapy for ALS.\n\nID: 42401196\nTitle: The Core Compendium of the European Society of Emergency Medicine Ultrasound Curriculum.\nAbstract: The diversity of healthcare systems across Europe has predictably resulted in significant variations in point-of-care ultrasound (PoCUS) training and practice for emergency medicine (EM). To encourage a more synchronized approach and address these inconsistencies, the European Society of Emergency Medicine (EUSEM) chartered its ultrasound section to develop a comprehensive curriculum compendium that should serve as a foundational guide for European Emergency Medicine PoCUS clinical and educational guidelines and policies. Under the leadership of a dedicated task force, the EUSEM ultrasound section developed this compendium to provide a structured, tiered framework designed to meet the needs of physicians at every skill level, from novice to advanced users. The compendium emphasizes applications that are currently practiced in different and diverse emergency departments in Europe, including a broad range of topics. An important goal was allowing flexibility to accommodate the unique resources and challenges of different healthcare environments, so that EM physicians can achieve PoCUS competencies matching their local circumstances and needs. To achieve this goal, good educational and clinical stewardship throughout this process is a key part to the success of advancing PoCUS in European EM. This compendium is intended as a resource for creating standardized yet adaptable training pathways. It represents a major step toward harmonizing and advancing PoCUS practice in European EM. Die Vielfalt der verschiedenen Gesundheitssysteme in Europa hat dazu gef\u00fchrt, dass grosse Unterschiede in der Ausbildung und Anwendung des Point-of-Care-Ultraschalls (PoCUS) in der Notfallmedizin bestehen. Um einen st\u00e4rker synchronisierten Ansatz zu f\u00f6rdern und diesen Unterschieden zu begegnen, hat die Europ\u00e4ische Gesellschaft f\u00fcr Notfallmedizin (EUSEM) ihre Ultraschallsektion damit beauftragt, ein umfassendes Curriculum-Kompendium zu entwickeln. Dieses soll als ein Leitfaden f\u00fcr Europ\u00e4ische Richtlinien und Standards f\u00fcr PoCUS in der klinischen Ausbildung in der Notfallmedizin dienen. Unter der Leitung einer Task Force hat die Ultraschallsektion der EUSEM dieses Kompendium erarbeitet, um Rahmenbedingungen zu schaffen, die den Bed\u00fcrfnissen von \u00c4rztinnen und \u00c4rzten auf jedem Kompetenzniveau - vom Einsteiger bis zum fortgeschrittenen Anwender - gerecht werden. Das Kompendium beinhaltet Ultraschallanwendungen, die in derzeit sehr diversen Notfallstationen in ganz Europa praktiziert werden, und deckt daher ein breites Spektrum PoCUS-Anwendungen in der Notfallmedizin ab. Ein zentrales Ziel dieser Arbeit war es, Flexibilit\u00e4t zu erm\u00f6glichen, um die spezifischen Merkmale wie auch Ressourcen der jeweiligen Gesundheitssysteme zu ber\u00fccksichtigen, sodass Notfallmediziner:innen PoCUS-Kompetenzen erwerben k\u00f6nnen, die ihren lokalen Gegebenheiten und Anforderungen entsprechen. Um das Ziel der Weiterentwicklung von PoCUS in der europ\u00e4ischen Notfallmedizin zu erreichen, ist ein entscheidender Erfolgsfaktor eine gute Begleitung sowohl in der klinischen Anwendung, wie auch in der Ausbildung.

Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42392626\nTitle: Workforce shortages and supported access to medical care for hospital employees: a scoping review.\nAbstract: This scoping review synthesises peer-reviewed and grey literature on supported access to medical care for hospital employees with existing physical health complaints to understand how it may reduce sickness absenteeism by promoting sustainable employability and to identify gaps and opportunities to inform the design and implementation of organisational supported care frameworks. We conducted this scoping review following the Arksey and O'Malley framework and Levac et al's methodological recommendations, reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extensions for Scoping Reviews (PRISMA-ScR). MEDLINE (Ovid), Embase (Elsevier), CINAHL (EBSCO) and Web of Science were searched from database inception to 8 November 2024. The search was updated on 18 May 2026. This was supplemented by forward and backward citation tracking of included peer-reviewed articles and targeted hand searching of Dutch grey literature in Medisch Contact , a leading Dutch professional journal for the medical profession, focusing on clinical practice, medical policy and professional issues. English-language or Dutch-language peer-reviewed publications and well-argued opinion pieces on healthcare workers' access to care (COVID-19 and beyond) in hospital or transferable settings were included. Sources focused on mental health or health promotion, financial aspects, personal protective equipment, patient access or healthcare worker utilisation, as well as non-English/Dutch sources, webpages and papers without full text, were excluded. ASReview was used for title and abstract screening following the SAFE procedure and full-text screening was conducted with team consensus. 27 publications were included from 36\u2009685 identified records. The literature was predominantly qualitative in nature and COVID-19-focused, yielding four themes (ethical considerations, multilevel challenges, target groups and strategies and outcomes). It also highlighted limited evidence on evaluated supported-access interventions and workforce outcomes beyond crises. Although supported access to medical care for hospital employees appears a promising multilevel, system-embedded strategy to reduce sickness absenteeism and promote sustainable employability in general, the evidence to substantiate and justify such strategies beyond acute crises is limited. Moreover, current literature lacks clear conceptualisation, operationalisation as well as robust implementation and evaluation frameworks. Addressing these gaps is a priority for future research to scientifically scaffold policies and frameworks to sustain a healthy and stable future hospital workforce.\n\nID: 42383392\nTitle: Role of Toll-like receptors and oral-gut-brain axis in neurodegenerative and neuropsychiatric disorders.\nAbstract: The oral-gut-brain axis is a path connecting the gastrointestinal tract and the central nervous system (CNS). The gut microbiota influences the immune system, metabolism, and nerve cells through the production of neurotransmitters and microbial metabolites that can cross the blood-brain barrier (BBB). The interplay between neuroinflammation and altered oral and gut microbiota is a bidirectional complex path modulated by inflammatory mediators. Recent studies suggest a potential role for Toll-like receptor (TLR) signaling pathways in the induction of neuroinflammation via the oral-gut-brain axis. As neuroinflammation is one of the key elements in the pathophysiology of neurodegenerative and neuropsychiatric disorders, this review was conducted to reflect on the pathophysiological pathways and clinical evidence on the role of TLR and inflammasome signaling pathways via oral-gut-brain axis in neurodegenerative diseases such as cognitive impairment, Alzheimer's disease, Multiple sclerosis, Parkinson's disease, Huntington's disease, and Amyotrophic lateral sclerosis, and psychiatric disorders such as major depressive disorder, anxiety disorders, schizophrenia, bipolar disorders, and Autism spectrum disorders. Because the contributing factors have not been fully understood yet, further studies could help provide novel therapeutic opportunities.\n\nID: 42374626\nTitle: Microbiome and metabolites impact enteric and central nervous systems in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) has been linked to gastrointestinal symptoms and alterations in the gut microbiota. The enteric nervous system (ENS) coordinates intestinal function and sits at the host-microbe interface. The mechanisms by which luminal changes relay to the central nervous system (CNS), where motor neurons reside, have yet to be completely defined. In this narrative review, we first present evidence from ALS patient cohorts and preclinical models alongside mechanistic studies of infection, dysbiosis, and related neurodegenerative diseases to discuss how the microbiota and its metabolites may affect the ENS and CNS in ALS. Next, we propose a plausible mechanism of ALS pathogenesis through the gut-microbiome-brain axis. We further offer a summary of clinical trials that have studied the impacts of the microbiota on human ALS. Finally, we discuss future directions for studies of microbiota-ENS-CNS interactions in ALS. Better understanding of the dynamic interactions among the microbiota, microbial metabolites, neuroactive metabolites, and inflammation through the ENS/CNS in ALS will provide innovative insights into ALS prevention and treatment.\n\nID: 42351201\nTitle: Learning a distance for the clustering of patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with median survival of 3-5 years. Patient responses to treatments vary widely, highlighting the need for personalized care. Clustering patients based on disease progression could improve prognosis, guide clinical decision-making, and optimize clinical trial design. This study aimed to identify robust ALS patient clusters using ALS Functional Rating Scale-Revised (ALSFRS-R) scores and to determine diagnostic parameters predictive of cluster membership, enabling earlier stratification and targeted management. Data from the Tours ALS center registry (April 1997-October 2023) were analyzed; after preprocessing, 353 patients monitored every three months between January 2004 and July 2023 with ALSFRS-R, clinical, biological, and demographic data were retained. After preprocessing to handle missing or aberrant data, a weakly supervised approach labeled patient pairs based on their ALSFRS-R sequences. These labels were used to train a classifier to learn a distance for off-the-shelf clustering algorithms. Multiple configurations were tested, varying clustering algorithms, dimensionality reduction method, and number of clusters. Random Forest (RF) model predicted cluster membership from diagnostic parameters. Optimal clustering was selected using silhouette score, validated with Kaplan-Meier survival analysis. Stability and robustness were assessed with the Adjusted Rand Index (ARI) and silhouette score respectively. Predictive performance was evaluated using specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV). Diagnostic parameters associated with clusters were identified using Kruskal-Wallis and chi-squared tests for continuous and categorical variables. Three clusters (n\u2009=\u2009139, 121, 93) were identified, demonstrating strong separation (silhouette\u2009\u2248\u20090.6) and high stability of results (ARI\u2009\u2248\u20090.7). Survival differed significantly among clusters: over 50% of patients in the third cluster survived beyond 50 months, compared to less than 25% in the other clusters. Thirteen diagnostic parameters-including ALSFRS-R subscores, IgG levels, albumin quotient, and time to diagnosis-were key predictors of cluster membership. Cluster prediction achieved specificity and NPV\u2009\u2248\u20090.75, with close sensitivity and PPV compared to state-of-the-art methods. This framework successfully stratifies ALS patients into clinically meaningful clusters, revealing underlying disease heterogeneity and providing strong prognostic insight. Such classification can facilitate personalized care, guide therapeutic decisions, and inform the design of targeted interventions to improve outcomes.

Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.\n\nID: 42332177\nTitle: Trace Elements Dyshomeostasis and Toxic Metals Neurotoxicity in Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, are defined by the progressive loss of neurons through interconnected pathological mechanisms, including oxidative stress, mitochondrial dysfunction, protein aggregation, and neuroinflammation. Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases.\n\nID: 42329291\nTitle: Targeting mitochondrial dysfunction and neuroprotection in neurodegenerative disorders: emerging therapeutic potential of berberine and polymeric nanoparticle-based delivery systems.\nAbstract: Major neurodegenerative disorders, such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis, are pathologically driven by mitochondrial failure and persistent neuroinflammation. Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique.\n\nID: 42317872\nTitle: Nutrients and bioactive compounds as modifiers of neurodegenerative trajectories: molecular mechanisms, translational barriers, and precision nutrition.\nAbstract: The Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS) are a growing health burden across the world with minimal disease-modifying treatment and therapy. It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions. Moreover, conceptualizing neurodegeneration as a nutrient-sensitive, systems level disorder, propose a mechanistically informed and integrative approach that combine targeted nutritional strategies with pharmacological and lifestyle therapies to more effectively modify neurodegenerative trajectories.\n\nID: 42313222\nTitle: Exercise-Driven NRF2 Activation as a Systemic Neuroprotective Strategy: Integrating Redox Biology, Muscle-Brain Crosstalk, and Therapeutic Targeting in Neurodegeneration.\nAbstract: Neurodegenerative diseases, including Alzheimer's, Parkinson's, and Huntington's diseases, are characterized by progressive neuronal dysfunction and loss. Recent evidence highlights the importance of the nuclear factor erythroid 2-related factor 2 (NRF2) pathway, a key regulator of cellular defense mechanisms, in maintaining neuronal health and function. A narrative literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar to identify relevant experimental, clinical, and review studies on NRF2 signaling, physical exercise, oxidative stress, muscle-brain crosstalk, and neurodegenerative diseases. Keywords included \"NRF2\", \"Nrf2/Keap1/ARE\", \"physical exercise\", \"exercise-induced oxidative stress\", \"myokines\", \"exerkines\", \"Alzheimer's disease\", \"Parkinson's disease\", \"Huntington's disease\", and \"amyotrophic lateral sclerosis\". NRF2 modulates the expression of a variety of antioxidant and cytoprotective genes, contributing to the protection of neurons against oxidative stress, inflammation, and protein aggregation, processes central to the pathogenesis of neurodegenerative diseases. Additionally, physical activity has been identified as a powerful modulator of NRF2 activation, with exercise offering neuroprotective effects through the induction of NRF2-mediated pathways. This review explores the interplay between NRF2 activation and physical exercise in the context of neurodegenerative diseases, detailing the molecular mechanisms by which exercise influences NRF2 activity to combat cellular damage and enhance neuroprotection. We discuss the therapeutic potential of combining exercise regimens with NRF2-targeted therapies, highlighting the promise of this dual approach in slowing disease progression, improving cognitive function, and enhancing quality of life in affected individuals. Furthermore, we examine the challenges and future directions for clinical implementation, including optimal exercise protocols and the development of NRF2-based pharmacological interventions. This review underscores the importance of NRF2 as a central mediator of neuroprotection and the therapeutic promise of physical activity in the management of neurodegenerative diseases.\n\nID: 42310788\nTitle: Co-development of a genetic care pathway for ALS: real-world perspectives from the North of England.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare, progressive neurodegenerative disorder, with a substantial proportion of cases attributed to genetic factors. Recent advances in gene discovery and genomic technologies have transformed ALS care by enabling genomic testing to inform prognosis, assess familial risk, and facilitate access to novel therapies. However, guidance on the delivery of genetic testing and counselling in ALS remains limited, leading to variability in clinical practice. In response, the Manchester Motor Neuron Disease (MND) Care Centre and the Manchester Centre for Genomic Medicine co-developed a structured genetic care pathway for ALS, drawing on real-world data, patient engagement, and multidisciplinary collaboration. A retrospective evaluation of 326 ALS patients at the Manchester MND Care Centre identified significant variability in genetic testing uptake, counselling practices, and record-keeping. Patient survey and engagement sessions revealed uncertainty regarding key genetic concepts and inconsistent recall of pre- and post-test discussions. Priorities for improvement included clearer communication, standardised discussions, and enhanced support for families following genetic findings. Consequently, the Greater Manchester ALS Genetic Testing Pathway was developed by a multidisciplinary team, incorporating consensus-based steps for patient identification, pre-test conversations, consent, testing, results disclosure, and post-test support. This pathway integrates genetic testing into routine ALS care, clarifies team responsibilities, and establishes a framework for ongoing evaluation using key performance indicators. Patient and staff feedback is used to support continuous improvement. The co-developed ALS genetic testing pathway provides a scalable model for standardising genomic care in mainstream clinical settings. By establishing clear processes for genetics discussions, consent, and follow-up, the pathway seeks to improve equity, transparency, and person-centred care. Ongoing evaluation and collaboration with patients, clinicians, and genetic services are essential to ensure the pathway remains responsive to scientific advances and evolving patient needs. Wider adoption of structured genetic pathways may facilitate the integration of genomics into care for rare diseases across healthcare systems.\n\nID: 42310298\nTitle: Sex-linked helicases DDX3X and DDX3Y regulate G-quadruplex-associated stress in neurons.\nAbstract: G-quadruplexes (G4s) are four-stranded nucleic acid structures that regulate virtually all nucleic acid-dependent cellular processes. At present, most functional studies involving G4s have focused on cancer cells. This study investigated how neurons respond to genotoxic stress induced by quarfloxin (CX-3543), a small molecule that stabilizes G4s. We found that quarfloxin treatment induced DNA damage in neurons, with double-strand breaks enriched in the nucleolus. Proteomic analysis revealed that quarfloxin promoted substantial protein changes, affecting networks associated with Alzheimer's, Parkinson's, and Huntington's diseases, and amyotrophic lateral sclerosis. Among the affected proteins, the G4 helicase DDX3X, encoded on the X chromosome, was upregulated, prompting further investigation of DDX3X and its Y-linked homolog DDX3Y in male and female neurons, respectively. RNA sequencing identified DDX3X- and DDX3Y-regulated gene networks involved in DNA damage responses, inflammation, cell cycle regulation, and stress-associated pathways, with notable sex-dependent differences. In human brain tissue, DDX3X expression and nuclear enrichment were increased in neurons from older females compared to younger individuals, with further elevation observed in Alzheimer's disease. Taken together, these findings identify DDX3X and DDX3Y as modulators of neuronal stress responses downstream of G4 stabilization and indicate that their induction is accompanied by activation of DNA damage response genes, as well as cell cycle- and inflammation-associated pathways, suggesting that sustained activation of these pathways may disrupt neuronal homeostasis. Our study provides insight into G4-dependent stress mechanisms in neurons and highlights sex-linked pathways that may contribute to brain aging and neurodegenerative disease vulnerability.\n\nID: 42304926\nTitle: Linking Neurodegeneration and Age-related Macular Degeneration: Unified Pathways and Intervention Strategies.\nAbstract: Age-related macular degeneration (AMD) is caused by the degeneration of photoreceptors and retinal pigment epithelium (RPE) along with drusen deposition and is the leading cause of vision loss in older adults. Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n\nID: 42299014\nTitle: Pathogenic Proteins Driving ALS Pathogenesis: Molecular Mechanisms and Translational Therapeutic Perspectives.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of motor neurons, with protein aggregation as a central pathological hallmark. Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.\n\nID: 42285406\nTitle: Recent advances in neurodegenerative diseases therapeutics: The inhibition of monoacylglycerol lipase strategy.\nAbstract: Neurodegenerative diseases share common pathophysiological mechanisms, including chronic neuroinflammation, glutamatergic excitotoxicity, oxidative stress, mitochondrial dysfunction, and disruptions in synaptic and lipid homeostasis. In this context, the endocannabinoid system has emerged as a key modulator of neuroimmune communication and neuronal survival. Within this system, Monoacylglycerol Lipase (MAGL) plays a central role by regulating the levels of the endocannabinoid 2-Arachidonoylglycerol (2-AG) while simultaneously contributing to the generation of arachidonic acid and pro-inflammatory eicosanoids. Pharmacological or genetic inhibition of MAGL increases 2-AG levels and concurrently reduces the biosynthesis of pro-inflammatory lipid mediators, thereby modulating microglial activation, astrocytic responses, and neuronal excitotoxicity. Preclinical studies in models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis consistently demonstrate that MAGL blockade attenuates neuroinflammation, preserves synaptic and neuronal integrity, improves motor and cognitive function, and, in some cases, delays disease progression. Although clinical evidence remains limited, the available data position MAGL as a metabolic convergence point between inflammation and neurodegeneration, suggesting that its modulation may represent a therapeutic strategy with disease-modifying potential.\n\nID: 42274906\nTitle: Environmental Factors Drive Neurodegenerative Diseases Through Glutamate Excitotoxicity: A Convergent Mechanistic Pathway.\nAbstract: This review illustrates how environmental stressors disrupt glutamate homeostasis via specific mechanisms: lead-induced thiol modification, manganese mediated yin yang 1 (YY1)-histone deacetylases (HDAC) repression, PM2.5-triggered microglia-astrocyte crosstalk, and advanced glycation end products (AGEs)-receptor for advanced glycation end products (RAGE)-nuclear factor kappa-B (NF-\u03baB) signaling from high-sugar diets. Together with genetic susceptibility and pigment epithelium-derived factor (PEDF), these factors impair astrocytic glutamate uptake, promoting synaptic glutamate accumulation. Subsequent N-methyl-D-aspartate (NMDA) and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptor overactivation triggers calcium overload, mitochondrial dysfunction, oxidative stress, and neuroinflammation-termed \"degenerative excitotoxicity\". Excitotoxicity manifests in Alzheimer's disease (amyloid-beta-excitatory amino acid transporter 2 (EAAT2) interplay), Parkinson's disease (subthalamic nucleus-driven excitatory storm), and amyotrophic lateral sclerosis (astrocytic failure versus neuronal cell-autonomous mechanisms). Future interventions need multi-target strategies, emerging technologies, and lifestyle modifications. This convergent framework offers a unified understanding linking environmental exposure to neurodegeneration and charts a roadmap toward mechanism-based prevention and treatment.\n\nID: 42274592\nTitle: The Role of Iron in Neuronal Homeostasis: A Double-Edged Sword.\nAbstract: Iron is an essential micronutrient that plays a central role in numerous biological processes. Despite its relatively low abundance in the human body, iron is particularly critical for brain function. Systemic and cerebral iron homeostasis is tightly regulated through coordinated mechanisms involving absorption, transport, storage, and recycling. Within the brain, iron metabolism is further controlled by the blood-brain barrier and specialized neural cell populations, including neurons, astrocytes, oligodendrocytes, and microglia. Iron is indispensable for neurodevelopment, supporting neurogenesis, myelination, and neurotransmitter synthesis. However, both iron deficiency and iron overload have detrimental consequences. Early-life iron deficiency disrupts neural development and leads to long-lasting cognitive, motor, and behavioral impairments, whereas excessive iron accumulation promotes oxidative stress, ferroptosis, and neuroinflammation. These mechanisms have been described to contribute to the pathogenesis of major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, neurodegeneration with brain iron accumulation, and amyotrophic lateral sclerosis. This review first outlines systemic and brain iron metabolism, highlighting how neural cells regulate homeostasis. Next, it examines iron's physiological roles, particularly in neurogenesis and neurodevelopment. Finally, it explores iron's involvement in neurodegenerative diseases, emphasizing neuroinflammation as a primary mechanism of iron toxicity.\n\nID: 42274555\nTitle: Polypharmacology of Pathway Crosstalk in Neurodegenerative Diseases: Chemical Modulation of Interconnected Signaling Networks.\nAbstract: Neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), arise from highly interconnected molecular and cellular abnormalities that progressively lead to neuronal dysfunction, synaptic failure, and cell death. This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.\n\nID: 42268433\nTitle: FUS-associated ALS in Taiwan: genetic spectrum, clinical features, and a founder haplotype of p.H517D.\nAbstract: To characterize the genetic spectrum and clinical features of FUS-associated amyotrophic lateral sclerosis (ALS) in a Taiwanese cohort and to investigate whether the recurrent p.H517D variant represents a founder mutation. All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.\n\nID: 42265995\nTitle: Two Patients With Juvenile-Onset, Rapidly Progressive Amyotrophic Lateral Sclerosis Associated With an SOD1 Variant (p.Asp125Gly) With Incomplete Penetrance.\nAbstract: Amyotrophic lateral sclerosis (ALS) patients are rarely encountered before age 25\u2009years, often associated with genetic variants. SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies.\n\nID: 42264545\nTitle: Nanotechnology-enabled targeting strategies for neurodegenerative disorders: role of functionalized nanoparticles.\nAbstract: Neurodegenerative disorders comprise a diverse group of progressive neurological diseases characterized by the gradual loss of neuronal structure and function. Conditions such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis arise from multifactorial mechanisms involving genetic susceptibility, environmental factors, and age-related cellular decline. Key pathogenic processes include oxidative stress, mitochondrial dysfunction, protein misfolding and aggregation, impaired axonal transport, Golgi fragmentation, and chronic neuroinflammation, all of which disrupt neuronal homeostasis and synaptic communication, ultimately leading to neuronal death. Hormonal imbalances further exacerbate these effects by promoting oxidative damage, inflammation, and metabolic dysfunction. Despite advances in understanding disease mechanisms, effective drug delivery remains challenging due to the restrictive nature of the blood-brain barrier. Recent developments highlight the potential of nanoparticle-based drug delivery systems to overcome these limitations. Functionalized nanoparticles enhance blood-brain barrier penetration, improve targeting specificity, and enable controlled drug release. These systems can deliver neuroprotective agents, antioxidants, peptides, and gene therapies directly to affected brain regions. Thus, integrating disease pathophysiology with nanotechnology-based strategies offers a promising approach for improving therapeutic outcomes and advancing precision treatment in neurodegenerative disorders.\n\nID: 42261159\nTitle: The Pivotal Role of HDAC6 in Amyotrophic Lateral Sclerosis: Neuroprotective Protagonist or Degenerative Adversary?\nAbstract: The review specifically examines the pivotal role of HDAC6 in the pathophysiological pathway of Amyotrophic Lateral Sclerosis (ALS), an escalating neurodegenerative ailment marked by the discerning damage to motor neurons. Several lines of evidence implicate inadequate proteostasis in significantly influencing neuronal degeneration. The accumulation of misfolded proteins and proteotoxicity are highlighted as significant factors in ALS pathophysiology. Key pathological hallmarks include ubiquitin-positive inclusions, disrupted RNA metabolism, cytoskeletal perturbations, and compromised axonal transport systems. HDAC6 dysregulation disrupts axonal transport, impairing mitochondrial function and increasing oxidative stress, leading to rapid motor neuron damage and cell death. The enzyme's aberrant deacetylation of \u03b1-tubulin destabilizes microtubules and impairs intracellular trafficking. Despite HDAC6's participation in these unfavorable processes, it also exerts neuroprotective properties. It deacetylates tubulin, promoting efficient axonal transport and autophagic clearance. HDAC6 helps form aggresomes and stress granules, which are essential for cellular defence against proteotoxic stress. Through its zinc finger ubiquitin-binding domain, HDAC6 interacts with polyubiquitinated proteins, facilitating their autophagic degradation. HDAC6 inhibition can boost autophagic flux and reduce protein aggregation, while its activation may amplify the protective effects. This dichotomous behaviour of HDAC6 may pose an obstacle to the design of targeted therapy. Illuminating the complex mechanisms through which HDAC6 influences neurodegeneration and neuroprotection is important before constructing effective treatments for ALS. The review provides a clear understanding of the complex role of HDAC6 in ALS pathogenesis and highlights potential strategies to improve the prognosis of people affected by this neurological illness.\n\nID: 42259394\nTitle: Natural monomer compounds in neurodegenerative diseases: Targeting ferroptosis and neuroinflammation.\nAbstract: Neurodegenerative diseases (NDDs), including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are characterized by progressive neuronal loss driven by oxidative stress, mitochondrial dysfunction, and chronic neuroinflammation. Ferroptosis, an iron-dependent and lipid peroxidation-associated form of regulated cell death, has recently been identified as a key contributor to neuronal vulnerability. Emerging evidence demonstrates that purified natural monomer compounds derived from medicinal plants exert potent neuroprotective effects by targeting ferroptosis and neuroinflammatory pathways. Representative agents such as curcumin, baicalin, resveratrol, and ginsenoside Rg1 activate nuclear factor E2-related factor-2 and glutathione peroxidase 4 signaling to preserve redox balance, while suppressing microglia-mediated inflammation through inhibition of toll-like receptor 4 pathways. This review highlights the interplay between ferroptosis and neuroinflammation in NDDs, summarizes the regulatory effects of bioactive herbal monomer compounds, and discusses recent advances in multi-omics profiling, nano-delivery strategies, and translational research. By modulating the ferroptosis-neuroinflammation axis, these compounds may represent promising therapeutic candidates for NDDs.\n\nID: 42259179\nTitle: Association of anti-glycolipid IgG with respiratory function decline in amyotrophic lateral sclerosis.\nAbstract: Effective treatments for amyotrophic lateral sclerosis (ALS) remain limited, underscoring the need to identify robust biomarkers associated with disease severity and prognosis. This study investigated whether immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-glycolipid antibodies are associated with clinical manifestations of ALS, particularly decline in respiratory function. This was a retrospective observational cohort study of the patients with ALS. Among patients with definite or probable limb-onset ALS, 11 patients in the glycolipid IgG-positive group were compared with 15 patients in the IgG-negative group, and 5 patients in the glycolipid IgM-positive group were compared with 9 patients in the IgM-negative group, with adjustment for age. Associations between anti-glycolipid antibody status and respiratory function were assessed using Kaplan-Meier survival analysis and Cox proportional hazards models. The time to decline of percent forced vital capacity (%FVC) below 80% and 60% was significantly shorter in the IgG-positive group than in the IgG-negative group (p\u00a0=\u00a00.002 and p\u00a0=\u00a00.025, respectively). Cox proportional hazards analysis demonstrated that IgG antibody positivity was an independent risk factor for earlier decline in %FVC to 80%. These findings suggest that anti-glycolipid IgG antibodies may be associated with respiratory function decline in ALS. Larger comprehensive studies will be required to validate these results and to elucidate the underlying pathophysiological mechanisms.\n\nID: 42247653\nTitle: Drivers of Rising Prevalence in Major Motor Neurodegenerative Diseases: Temporal Trends in Sweden and France (2003-2022).\nAbstract: The prevalence of Parkinson disease (PD), multiple sclerosis (MS), and motor neuron diseases (MNDs) is rising globally. However, it is unclear to what degree this is related to an increase in incidence or to improved survival after diagnosis. We performed 2 nationwide, population-based, retrospective cohort studies, including all individuals living in Sweden between 2001 and 2016 and living in France between 2009 and 2022, respectively. Pooled mixed-effects regression models, with country as a random effect, were used to determine temporal trends in prevalence, crude and age-standardized and sex-standardized incidence, and age and life expectancy at diagnosis. Annualized prevalence of PD, MS, and MNDs increased significantly between 2003 and 2022 in the pooled model (PD: prevalence ratio [PR] per year = 1.014, p < 0.001; MS: PR = 1.029, p < 0.001; MND: PR = 1.028, p < 0.001). While the crude incidence of both PD and MS remained nearly stable over time (PD: incidence rate ratio [IRR] per year = 0.998, p < 0.001; MS: IRR = 0.992, p < 0.001), the standardized incidence showed a more marked decrease for PD (IRR = 0.986, p < 0.001) while remaining almost unchanged for MS (IRR = 0.995, p < 0.001). For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001). Life expectancy at diagnosis of PD increased between 2003 and 2013 (+0.95 months per calendar year, p < 0.001) and then decreased between 2013 and 2022 (-1.20 months, p = 0.002), while it increased significantly over the entire study period for MS (+2.35 months, p < 0.001) and MNDs (+0.34 months, p = 0.01). These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence. Depending on the mechanism that drives prevalence, whether increased incidence reflecting changing risk factor exposures, improved survival due to therapeutic advances, or demographic aging of the population, inferences about underlying causes differ substantially between PD, MS, and MNDs, with direct implications for health care planning and etiologic research.\n\nID: 42245509\nTitle: The microbiota-tryptophan-brain axis in neurodegenerative diseases: pathogenic mechanisms, disease-specific roles, and translational therapeutics.\nAbstract: The pathogenesis of neurodegenerative diseases (NDDs) such as Alzheimer's disease (AD) and Parkinson's disease (PD) is very complex. Recent studies have shown that gut microbiota and their metabolites play a key role in the progression of these diseases. Tryptophan (Trp) is an essential amino acid, which mainly produces a variety of biologically active compounds in the intestine through the metabolism of indole pathway, Kynurenine pathway (KP) and serotonin pathway, including indole derivatives, Kynurenine (KYN) and serotonin (5-HT). These metabolites affect the central nervous system (CNS) through the Microbiota-gut-brain axis (MGBA) and affect CNS in a variety of mechanisms, including immune regulation, neuroprotection and maintenance of intestinal barrier function. They are involved in key pathological processes such as neuroinflammation, oxidative stress and pathological protein aggregation. This paper systematically reviews the mechanism of the role of Trp metabolites derived from gut microbiota in NDDs, and explores their specific roles in AD, PD, Amyotrophic Lateral Sclerosis (ALS) and Huntington's disease (HD), and summarizes the potential therapeutic value of the current pathway strategy. These strategies include nutritional intervention, targeted microbiome therapy [such as probiotic and fecal microbiota transplantation (FMT)], and metabolite-derived drugs. Future research must clarify its dynamic mechanism in the human body, develop relevant biomarkers, and promote personalized prevention and treatment strategies through clinical transformation, so as to provide a new direction for early intervention and treatment of NDDs.\n\nID: 42243993\nTitle: Hyperoside protects against poly-GR-mediated neurodegeneration via regulation of mitochondrial fission and oxidative stress in C9orf72-associated ALS.\nAbstract: Arginine-rich poly-glycine-arginine (poly-GR), a toxic dipeptide repeat protein generated from C9orf72 hexanucleotide repeat expansion, drives mitochondrial dysfunction, oxidative stress, and neuronal loss in amyotrophic lateral sclerosis (ALS). Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS.\n\nID: 42236747\nTitle: Targeting mitophagy for neuroprotection: mechanisms and therapeutic opportunities.\nAbstract: Mitochondria are essential for neuronal energy production, cellular homeostasis, and overall neuronal function. Due to their high metabolic demands and limited regenerative capacity, neurons are particularly vulnerable to mitochondrial dysfunction, which leads to ATP depletion, excessive reactive oxygen species (ROS) production, and calcium imbalance-ultimately causing oxidative stress, metabolic disruption, and neuronal death. Mitophagy is a selective process that removes damaged mitochondria through the autophagy-lysosome pathway. As a key mechanism of mitochondrial quality control, mitophagy preserves energy production, limits oxidative damage, and maintains mitochondrial network integrity. This process is regulated by pathways such as PINK1-Parkin and receptor-mediated mechanisms involving BNIP3 and FUNDC1, all of which help sustain cellular health by preventing mitochondrial dysfunction. Impaired mitophagy is a common feature of several neurodegenerative diseases, including Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS), and Huntington's disease, exacerbating mitochondrial damage and neuronal stress. Emerging therapeutic strategies that target mitophagy-ranging from pharmacological agents and gene therapies to dietary interventions-show promise in restoring mitochondrial quality and protecting neurons from degeneration. Nevertheless, challenges remain in translating these findings into effective clinical treatments. Mitophagy represents a critical mechanism for preserving neuronal integrity and offers a compelling target for innovative therapies against neurodegenerative disorders.\n\nID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.\n\nID: 42404433\nTitle: Beyond motor neurons: peripheral TDP-43 pathology in skeletal muscle and intramuscular nerves in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive neurodegenerative disease characterized by accumulation of the 43-kDa TAR DNA-binding protein (TDP-43). This neuropathological signature has been well documented within the CNS; however, recent findings indicate that the phosphorylated TDP-43 additionally deposits in peripheral tissues, including skeletal muscle and intramuscular nerves. These data warrant a change of view from a neurocentric perspective of amyotrophic lateral sclerosis pathogenesis towards a broader concept of TDP-43 proteinopathy extending both within and beyond the nervous system. In this review, we focus on current evidence supporting the presence of TDP-43 pathology in amyotrophic lateral sclerosis skeletal muscle, examining its topographic distribution, molecular characteristics and associations with intramuscular nerve bundles. We also discuss the susceptibility of intrinsic muscle cells, disrupted axonal transport and impairment in protein quality control. Phosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease. Moreover, we discuss the relevance of these findings to amyotrophic lateral sclerosis pathogenesis and potential therapeutic implications.\n\nID: 42401978\nTitle: Regional wasteosome accumulation across neurodegenerative diseases points to a shared underlying mechanism potentially related to glymphatic insufficiency.\nAbstract: The glymphatic system plays a key role in clearing waste products from the brain and is essential for maintaining brain homeostasis. When dysfunctional, it appears to contribute to pathological changes that exacerbate brain disorders, including neurodegenerative diseases. Additionally, wasteosomes, also known as corpora amylacea, are structures that function as waste containers and are thought to increase in response to chronic glymphatic insufficiency. Hence, in this study, we evaluated whether the accumulation and distribution of wasteosomes are compatible with both the potential role of wasteosomes as a hallmark of the chronic glymphatic insufficiency and the presence of this insufficiency in certain neurodegenerative diseases. Accordingly, brain tissue from 185 donors was analysed, including cases of Alzheimer's disease, amyotrophic lateral sclerosis with TDP-43 proteinopathy, frontotemporal lobar degeneration with TDP-43 or tau proteinopathy, and non-diseased controls. Wasteosomes were examined across 28 brain regions comprised within 5 major brain areas, using region-specific scoring systems. Analysis was conducted through variance and covariance analyses, along with decision tree procedures. The findings reveal that wasteosomes are consistently found in specific critical regions, with a higher burden in donors with neurodegenerative diseases compared with controls. These regions are independent of the regional distribution of the underlying proteinopathy, and are potentially associated with glymphatic drainage pathways. From an integrated perspective, although further studies are required, the increased presence of wasteosomes in these critical regions across all diseased groups is consistent with the potential presence of chronic glymphatic insufficiency in these diseases.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42399370\nTitle: Therapeutic targeting of the conserved region within the low-complexity domain of TDP-43 is neuroprotective and extends survival in amyotrophic lateral sclerosis mice.\nAbstract: Autosomal dominant mutations in TARDBP, encoding TAR DNA-binding protein 43 (TDP-43), cause amyotrophic lateral sclerosis (ALS), and TDP-43 pathology is a hallmark of multiple aging-associated neurodegenerative diseases. Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.\n\nID: 42377311\nTitle: Could anticholinergics accelerate ALS progression? A critical perspective on drug safety and disease vulnerability.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with limited treatment options and diverse symptoms necessitating active management. Anticholinergic medications are frequently used in ALS care, particularly for sialorrhea and mood disturbances. Their cumulative effects, termed anticholinergic burden, may pose underrecognized risks in this neurologically vulnerable population. This review highlights a plausible safety signal and outlines priorities for future research. This narrative review synthesizes evidence from non-ALS populations reporting associations between higher anticholinergic burden and cognitive decline, respiratory complications, functional deterioration, and mortality. Evidence was identified through targeted PubMed/MEDLINE and Embase searches with reference chaining, emphasizing recent and seminal studies. Mechanistic overlap with ALS pathophysiology, including neuromuscular junction disruption, impaired cholinergic signaling, and neuroinflammation, supports biological plausibility for harm. Current ALS guidelines do not address cumulative anticholinergic exposure, leaving clinicians without a framework for evaluating risk or deprescribing. This article proposes a testable hypothesis that anticholinergic burden may represent a clinically relevant yet unmeasured risk factor in ALS. Emerging pharmacoepidemiologic methods and validated burden tools offer approaches to quantify exposure and evaluate relationships with ALS outcomes, supporting safer symptomatic management. Prioritizing longitudinal studies and integrating burden assessment into multidisciplinary care may help clarify risk.\n\nID: 42375130\nTitle: Blood-based biomarker discovery in motor neuron disease using nucleic acid-linked immuno-sandwich assay.\nAbstract: Motor neuron disease (MND) presents with phenotypic heterogeneity, is diagnostically challenging, and has poor prognosis. The absence of accessible blood-based biomarkers has hampered progress towards precision medicine. Highly sensitive immunoassays offer considerable promise for identifying blood-based biomarkers informing underlying pathophysiology and enabling accurate diagnosis and monitoring. We report findings on parallel use of the ultra-sensitive multiplexed NUcleic Acid-Linked Immuno-Sandwich Assay (NULISA) and single molecule array (Simoa), to interrogate serum from people with MND. Sera (48 MND, 38 controls) were analysed using a NULISAseq targeted neurodegenerative panel and a Simoa neurofilament light chain (NfL) and glial fibrillary acid protein (GFAP) duplex assay. Neurofilament light and heavy chain, total tau (t-tau), phosphorylated tau (pTau)-181, pTau-217, pTau-231, fatty acid binding protein 3, amyloid beta (A\u03b2) 38 and A\u03b240 levels were significantly elevated in MND (P < 0.05). Simoa and NULISAseq assays demonstrated strong correlations for NfL and GFAP (r > 0.90). Use of the multiplexed NULISAseq panel confirmed a well-established NfL elevation in MND, and replicated findings for other proteins from recent studies. Results add confidence in the validity and reproducibility of biomarkers identified using NULISAseq, while offering insights into the underlying pathophysiology and heterogeneity of MND.\n\nID: 42365390\nTitle: Lysophagy protects against ANXA11 amyloid fibril toxicity and propagation in FTLD.\nAbstract: Accumulation of Annexin A11 (ANXA11) aggregates is a distinct pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.\n\nID: 42357346\nTitle: Advancing MSC-EV Therapies: Harnessing Preconditioning and Mito-EVs to Tackle Neuroinflammation and Neurodegeneration.\nAbstract: Neuroinflammation plays a central role in the onset and progression of neurodegenerative disorders. Several disease-modifying therapies have been developed to target neuroinflammatory pathways in specific disorders. However, their ability to stop disease progression or restore neuronal and mitochondrial homeostasis remains limited. This is still a major unmet clinical need. In this context, mesenchymal stromal cell (MSC)-derived Extracellular Vesicles (EVs) have emerged as a promising cell-free therapeutic strategy due to their ability to modulate immune responses and promote neuroprotection through the delivery of bioactive cargo. Recent evidence has identified a distinct subset of EVs, known as mitochondrial EVs (mito-EVs), which carry mitochondrial DNA, proteins, and functional components. These vesicles may uniquely influence cellular bioenergetics, redox balance, and neuroinflammatory signaling, offering additional therapeutic potential compared to conventional MSC-EVs. This review summarizes the role of MSC-derived EVs in neuroinflammatory disorders, with a particular focus on mito-EVs. It also discusses preconditioning strategies to enhance EV efficacy, including hypoxic, inflammatory, pharmacological priming and genetic engineering approaches. Finally, we critically evaluate current preclinical evidence regarding the treatment of major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Multiple Sclerosis, and Amyotrophic Lateral Sclerosis, as well as Traumatic Injury, highlighting the key challenges for clinical translation.\n\nID: 42352358\nTitle: Extracellular Pgk1 or Its Derived Short Peptide Interacted with Membrane-Associated Enolase 2 Receptor: A Potential Therapy for ALS Motor Neuron Degeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) remains an intractable motor neuron (MN) disease with a growing patient population and few effective treatments. Here, we review how extracellular phosphoglycerate kinase 1 (ePgk1) improves neurite outgrowth of MNs (NOMN) and axonal growth, both in vitro and in vivo. Our group first elucidated a novel non-canonical function of ePgk1 as a cross-tissue mediator between nerve and muscle tissues. We then discovered that neural membranous Enolase 2 (Eno2) serves as a receptor of ligand ePgk1 and that ePgk1-Eno2 interaction suppresses the Rac1-GTP/p-Pak1-T423/p-P38-T180/pMK2-T334/p-Limk1-S323 axis, reducing p-Cofilin and promoting NOMN and axonal growth, finally suggesting that the 419th aspartic acid residue of Eno2 mediates this interaction. In a crucial preclinical step, we truncated two short 16-amino-acid derivatives from Pgk1, FD-1/-2, each mediating neuroprotection comparable to that of full-length 417-amino-acid Pgk1 in ALS animal models, in terms of improvements of innervated neuromuscular junction, MN cell bodies, motor performance, and endpoint prolongation. In this context, we also discuss the opposite function driven by Eno1-plasminogen interaction and by Eno2-ePgk1 interaction; the latter results in unfavorable for tumorigenesis. Unlike intracellular Pgk1 roles, ePgk1 is an extracellular factor with anti-angiogenic properties, further positioning ePgk1 and its FD-1/-2 as promising protein/peptide drugs for ALS treatment.\n\nID: 42351263\nTitle: Dynamic integration of skeletal muscle signals via extracellular vesicles in motor neuron diseases.\nAbstract: Extracellular vesicles (EVs) are heterogenous lipid bilayer-enclosed particles secreted by virtually all cell types. They encapsulate a diverse array of bioactive molecules, including proteins, lipids, nucleic acids, and metabolites, which can be transferred to recipient cells, thereby modulating their function and phenotype. In recent years, skeletal muscle-derived EVs (SkM-EVs) have emerged as key players in the bidirectional communication between skeletal muscle and motor neurons, contributing to the establishment and maintenance of neuromuscular homeostasis. Disruptions in this intercellular signalling have been implicated in the pathophysiology of motor neuron diseases (MNDs) such as spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS). In these contexts, SkM-EVs may contribute to disease progression by delivering pathogenic cargo, including misfolded proteins and aberrant RNAs, to motor neurons. A comprehensive understanding of SkM-EV biology, particularly their roles in neuromuscular communication, could offer critical insights into disease mechanisms and identify novel opportunities for biomarker discovery and therapeutic intervention. This review synthesizes current knowledge on the functional roles of SkM-EVs in motor neuron health and disease and evaluates their potential as diagnostic tools and therapeutic vectors in the context of MNDs.\n\nID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.\n\nID: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\n\nID: 42341897\nTitle: Programmed axon degeneration gene variants in human disease.\nAbstract: Programmed axon degeneration (PAD; also known as Wallerian degeneration) is a conserved pathway controlling axon breakdown following injury or metabolic stress. PAD is driven by the depletion of nicotinamide adenine dinucleotide (NAD) through loss of the pro-survival enzyme NMNAT2 and activation of the pro-degenerative NADase SARM1. Recent genetic studies have identified pathogenic variants in PAD pathway enzymes associated with severe neurodegenerative phenotypes. Pathogenic variants in NAMPT, NMNAT1, NMNAT2, and SARM1 have been identified and will be discussed in this review. NAMPT variants cause sensory and motor neuropathy with neurodevelopmental symptoms. NMNAT1 variants are well-characterized causes of Leber Congenital Amaurosis type 9, while NMNAT2 variants result in peripheral neuropathies with childhood onset. SARM1 gain-of-function variants with constitutively active NADase activity are enriched in amyotrophic lateral sclerosis patients. These findings demonstrate that maintaining proper NAD homeostasis is crucial for axon survival, and disruption through genetic variants leads to distinct neurodegenerative outcomes. Understanding these rare variants provides insight into PAD mechanisms and supports development of broad-spectrum neuroprotective therapies targeting this pathway. Current therapeutic approaches include SARM1 inhibitors in clinical trials, gene therapy, and NAD precursor supplementation, offering hope for treating multiple neurodegenerative diseases.\n\nID: 42341118\nTitle: Isoform-specific steric zippers drive aberrant assembly and mislocalization of shortened TDP-43.\nAbstract: Prion-like domain (PrLD)-mediated aggregation and concomitant dysfunction of the essential RNA-binding protein transactive response (TAR) DNA-binding protein of 43 kilodaltons (TDP-43) is a common feature of multiple debilitating neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.\n\nID: 42341041\nTitle: IRE1 regulates the proteostasis of TDP-43/TARDBP in ALS/FTD through ribosome-associated quality control.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are progressive neurodegenerative disorders characterized by motor neuron degeneration, leading to muscle weakness, atrophy, and cognitive impairments. A defining pathological hallmark of ALS/FTD is the cytosolic mislocalization and accumulation of TAR DNA-binding protein 43 (TDP-43), highlighting its critical role in ALS pathogenesis. However, the molecular mechanisms underlying TDP-43 proteostasis remain poorly understood. Through a genetic screening approach, we identify inositol-requiring enzyme 1 (IRE1), an endoplasmic reticulum-resident transmembrane protein, as a potent suppressor of TDP-43 protein levels. Furthermore, we show that ribosome-associated quality control (RQC) factors play a crucial role in regulating TDP-43 proteostasis and cellular toxicity. Activation of the RQC pathway prevents excessive accumulation of TDP-43 and associated toxicity. Mechanistically, our findings suggest that IRE1 regulates TDP-43 protein level by promoting the degradation of aberrant TDP-43 translation product through the RQC pathway. IRE1 acts canonically to enhance the transcription of the RQC core component Clbn/NEMF and noncanonically to physically interact with Clbn/NEMF, thereby ameliorating TDP-43-induced proteotoxicity. Moreover, ectopic expression or pharmacological activation of IRE1 alleviates TDP-43 pathology and restores cognitive function in the TDP-43 A315T ALS mouse models. Collectively, our study identifies a role for IRE1 in the translational quality control of TDP-43 and establishes its potential as a therapeutic target for ALS/FTD.\n\nID: 42335888\nTitle: An emergent disease-associated motor neuron state precedes cell death in ALS.\nAbstract: To define molecular determinants of motor neuron degeneration in amyotrophic lateral sclerosis (ALS), we generated longitudinal single-nucleus transcriptomes and chromatin accessibility profiles of spinal motor neurons together with spatial transcriptomics from the SOD1-G93A mouse model. Vulnerable alpha motor neurons showed thousands of molecular changes, marking a transition into a distinct cell state we named \"disease-associated motor neurons\" (DMs). We identified transcription factor networks that govern how healthy cells transition into DMs and those associated with motor neuron subtype-selective vulnerability. Upregulation of DM-associated transcription factors in human motor neurons induced key features of DMs, demonstrating an active regulatory component. Human ALS spinal cord single-nucleus RNA sequencing data demonstrated conservation of the DM signature in alpha motor neurons, and human orthologs of regions differentially accessible in SOD1-G93A mouse motor neurons were enriched for ALS genetic risk variants. Together, these findings establish a conserved, genetically linked motor neuron signature in ALS.\n\nID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

This phenomenon is primarily driven by demographic factors\u2014specifically population ageing and growth\u2014rather than an increase in per-capita disease risk.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe perceived surge in ALS prevalence is a multifaceted epidemiological outcome. Demographic studies conducted over the last two decades provide compelling evidence that the escalation in case numbers is largely a byproduct of an ageing global population. Because ALS incidence peaks at ages 70\u201379, the demographic shift toward longer life expectancies disproportionately increases the size of the high-risk cohort. Furthermore, improved clinical management, such as the use of gastrostomy for nutritional support and better multidisciplinary care, has increased survival rates, thereby inflating the total number of individuals living with the disease at any given time. While environmental factors, genetic risks, and potential changes in ascertainment exist, current meta-analytical evidence suggests that the rising prevalence of motor neuron diseases reflects a true increase in absolute cases driven by demographic expansion and enhanced longevity post-diagnosis.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Population ageing accounts for approximately 46% of the increase in disability-adjusted life years (DALYs) in MND-related studies.\n* Age-standardized rates of MND have actually declined in many settings, suggesting that individual risk may be stable or decreasing.\n* Gastrostomy interventions like PEG or RIG, while primarily nutritional, have been shown to increase survival rates for ALS patients.\n* The global incidence of ALS is 1.65 per 100,000 person-years, with a notably higher disease burden in high-income countries compared to middle-income settings.\n* There is a significant sex disparity in ALS burden, with prevalence rate ratios indicating a lower burden in females compared to males.\n* Improved multidisciplinary palliative care facilitates better referral and intervention timing, indirectly contributing to the survival-driven increase in prevalence.\n* Environmental exposures and dietary factors are increasingly linked to the pathogenesis, suggesting that \"epidemiological shifts\" are complex and interact with demographic changes.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations."

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations."

With limited treatment options, identifying modifiable risk factors that impact ALS survival is an important goal. Air pollution may be one such risk factor, yet the research on this topic is limited. METHODS: We assessed survival for ALS patients at the University of Michigan Pranger ALS Clinic who were recruited to participate in a prospective cohort study between 2009 and 2022. Participants\u2019 personal characteristics were linked with residential air pollutant levels of fine particulate matter mass (PM2.5), nitrogen dioxide (NO2), and ozone (O3), as well as several particle components, including black carbon (BC), nitrate, sulfate, and sea-salt (as a negative control) over follow-up. To assess the role of air pollution on ALS mortality we used time-dependent Cox proportional hazards models with days from diagnosis as the time axis, adjusted for potential confounders and co-pollutants. RESULTS: Across the 1,276 total years of person-time during follow-up (2.7\u2009\u00b1\u20092.5 years per participant) there were 329 deaths. In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1\u00a0\u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death. The other pollutants were not associated with death in participants with ALS . CONCLUSIONS: This finding suggests a seven month longer median survival for a 2.1\u00a0\u00b5g/m3 decrease in 1-year average PM2.5, which is significant given that ALS lacks a cure and that existing treatments only extend survival by a few months."

"abstract_text": "ID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants."

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care."

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS."

While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies."

Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed.

SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies.

These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies."

These demands place substantial strain on family carers and often require input from paid homecare workers. Despite their essential role, little is known about how homecare workers contribute to complex MND care, how they integrate within multidisciplinary teams, or how families experience their involvement. To examine people living with MND and family members' perspectives of homecare worker roles, responsibilities, relationships when complex interventions are required. A qualitative secondary analysis of data from two prior studies exploring home ventilation and tracheostomy ventilation in MND. Seven relevant NVivo nodes and 33 sub-nodes from interviews with 68 participants were re-coded using a deductive framework. Fourteen new nodes and 11 sub-nodes were generated and organised into three themes: care commissioning and provision; relationships; and the home environment. Participants described fragmented and inconsistent care commissioning, requiring families to advocate persistently for adequate support. Challenges included funding barriers, high staff turnover, and limited MND-specific knowledge, which undermined trust and compromised safe, effective care. Relationships with homecare workers ranged from highly valued, stable partnerships to strained interactions shaped by competence concerns, emotional labour, and mismatched expectations. The presence of homecare workers and medical equipment transformed the home into a quasi-clinical space, reducing privacy, disrupting routines, and requiring households to adapt around care provision. Yet strong relationships with homecare workers could enhance quality of life. Homecare workers play a critical role in delivering complex home-based MND care, yet quality is inconsistent. Improving training, stabilising staffing, supporting care coordination, and preparing families for the relational and environmental impact of homecare are essential for fostering sustainable, trusted care relationships, and improving outcomes for people living with MND and their families. Paid homecare support for people with motor neurone disease: Insights from people with MND and their families This study explores how people living with motor neurone disease (MND), and their family members, experience support from paid homecare workers when complex medical interventions, such as ventilation, feeding tubes, suction and hoists are needed at home. As care needs increase, families often need help from paid homecare workers, yet no research has asked families about what this support is like. To address this, we re-analysed interview data from two earlier studies about living with home ventilation in MND, and developed three main themes: Care commissioning and provision: Participants described the process of securing a care package as confusing and often exhausting, with multiple organisations involved. Families frequently had to push to get the support they needed. Problems included shortages of trained staff, high staff turnover, and delays caused by complex funding rules. Relationships with homecare workers: Good homecare workers made a huge positive difference. Relationships with homecare workers ranged from highly positive, built on trust, skill and becoming \u2018part of the family\u2019, to strained, particularly when workers lacked MND-specific training or confidence with equipment. Trust was crucial: when present it eased pressure on families but when absent it increased stress and vigilance. Impact on the home environment: Having carers in the house, changed home life, reducing privacy, disrupting household routines, and living spaces became filled with medical equipment and ever-present homecare workers. Families described feeling like hosts in their own homes and sometimes having to manage the emotional labour of being polite or accommodating even when exhausted. Overall, the study shows that homecare workers play an essential role in complex MND care, but quality is inconsistent. Better coordination and support for families to manage these close relationships within the home are vital to reduce pressure on families and improve quality of life."

People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170\u00a0h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected."

This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50).

The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease."

While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients."

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe perspective evaluated is the potential rise in the prevalence and incidence of Amyotrophic Lateral Sclerosis (ALS). The literature indicates that while age-standardized rates have declined in some regions, the absolute global burden of ALS is rising, primarily driven by demographic factors like population aging, population growth, and potentially true increases in incidence in certain populations.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe increasing global burden of ALS is a multifactorial phenomenon. While demographic shifts (aging and population growth) account for a significant portion of the absolute increase in cases, evidence suggests that for MNDs, there is a documented increase in both crude and standardized incidence, distinguishing it from other neurodegenerative conditions where prevalence rises are survival-driven.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe epidemiological landscape of Amyotrophic Lateral Sclerosis (ALS) demonstrates a divergence between age-standardized rates and absolute disease burden. Recent analyses indicate that \"Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%).\" This reflects a broader trend where \"Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially.\" Notably, epidemiological patterns for MNDs appear distinct from other neurodegenerative conditions, as \"These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence.\" This is supported by data stating \"For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001).\" While research into causes is ongoing, environmental factors remain a focus, with studies suggesting that \"In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1 \u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Global prevalence of ALS is estimated at 5.05 per 100,000 population.\n* The disease burden is significantly higher in high-income countries compared to middle-income nations.\n* Male individuals consistently show a significantly higher disease burden than females, with prevalence rate ratios around 0.69.\n* Diagnostic yield for pathogenic variants in ALS is approximately 15.90%, with higher yields (36.95%) in familial cases.\n* Tofersen treatment for SOD1-ALS marks a shift toward functional recovery modeling, creating a new \"Recovery Model System of Care.\"\n* Air pollution (PM2.5) exposure is associated with increased mortality in ALS patients.\n* ALS incidence peaks in the 70-79 age range.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

These demands place substantial strain on family carers and often require input from paid homecare workers. Despite their essential role, little is known about how homecare workers contribute to complex MND care, how they integrate within multidisciplinary teams, or how families experience their involvement. To examine people living with MND and family members' perspectives of homecare worker roles, responsibilities, relationships when complex interventions are required. A qualitative secondary analysis of data from two prior studies exploring home ventilation and tracheostomy ventilation in MND. Seven relevant NVivo nodes and 33 sub-nodes from interviews with 68 participants were re-coded using a deductive framework. Fourteen new nodes and 11 sub-nodes were generated and organised into three themes: care commissioning and provision; relationships; and the home environment. Participants described fragmented and inconsistent care commissioning, requiring families to advocate persistently for adequate support. Challenges included funding barriers, high staff turnover, and limited MND-specific knowledge, which undermined trust and compromised safe, effective care. Relationships with homecare workers ranged from highly valued, stable partnerships to strained interactions shaped by competence concerns, emotional labour, and mismatched expectations. The presence of homecare workers and medical equipment transformed the home into a quasi-clinical space, reducing privacy, disrupting routines, and requiring households to adapt around care provision. Yet strong relationships with homecare workers could enhance quality of life. Homecare workers play a critical role in delivering complex home-based MND care, yet quality is inconsistent. Improving training, stabilising staffing, supporting care coordination, and preparing families for the relational and environmental impact of homecare are essential for fostering sustainable, trusted care relationships, and improving outcomes for people living with MND and their families. Paid homecare support for people with motor neurone disease: Insights from people with MND and their families This study explores how people living with motor neurone disease (MND), and their family members, experience support from paid homecare workers when complex medical interventions, such as ventilation, feeding tubes, suction and hoists are needed at home. As care needs increase, families often need help from paid homecare workers, yet no research has asked families about what this support is like. To address this, we re-analysed interview data from two earlier studies about living with home ventilation in MND, and developed three main themes: Care commissioning and provision: Participants described the process of securing a care package as confusing and often exhausting, with multiple organisations involved. Families frequently had to push to get the support they needed. Problems included shortages of trained staff, high staff turnover, and delays caused by complex funding rules. Relationships with homecare workers: Good homecare workers made a huge positive difference. Relationships with homecare workers ranged from highly positive, built on trust, skill and becoming \u2018part of the family\u2019, to strained, particularly when workers lacked MND-specific training or confidence with equipment. Trust was crucial: when present it eased pressure on families but when absent it increased stress and vigilance. Impact on the home environment: Having carers in the house, changed home life, reducing privacy, disrupting household routines, and living spaces became filled with medical equipment and ever-present homecare workers. Families described feeling like hosts in their own homes and sometimes having to manage the emotional labour of being polite or accommodating even when exhausted. Overall, the study shows that homecare workers play an essential role in complex MND care, but quality is inconsistent. Better coordination and support for families to manage these close relationships within the home are vital to reduce pressure on families and improve quality of life.\n\nID: 42402806\nTitle: Very low-amplitude muscle activity increases probability of motor evoked potentials in healthy individuals and in amyotrophic lateral sclerosis.\nAbstract: Muscle contraction increases motor evoked potential (MEP) amplitude, decreasing motor threshold (MT). Correspondingly, trials where baseline EMG amplitude exceeds a specified threshold are often rejected. We aimed to investigate the influence of motor activity below such a threshold of MEP amplitude. We retrospectively analysed TMS-EMG data collected during resting MT (RMT) measurement in 45 healthy control subjects (1794 data points) and 35 people with amyotrophic lateral sclerosis (ALS; 1229 data points). Trials with de-meaned root mean squared (RMS) EMG amplitude of >10\u00a0\u00b5V throughout the 200\u00a0ms prior to stimulation were rejected. Generalised linear mixed-effects models assessed effects of muscle activity below this rejection threshold on the probability of evoking an MEP with peak-to-peak amplitude of \u226550\u00a0\u00b5V. Greater sub-rejection-threshold activity significantly increases MEP probability in control subjects and people with ALS. Models predicted a 38%-43% increase in MEP probability when baseline RMS-EMG amplitude increased from 1 $\\hskip.001pt 1$ to 9\u00a0\u00b5V. Sub-rejection-threshold baseline activity was significantly greater in ALS than control subjects. Below a typical rejection threshold, greater baseline RMS-EMG amplitudes markedly increase the probability of evoking MEPs with peak-to-peak amplitude of \u226550\u00a0\u00b5V. Effects of sub-rejection-threshold muscle activity should be accounted for when comparing RMT measures, particularly between cohorts where such activity differs, such as ALS and control subjects.\n\nID: 42399099\nTitle: Global epidemiology of amyotrophic lateral sclerosis: a systematic review and meta-analysis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with the global epidemiological profile remaining incompletely understood. While previous systematic reviews existed, an updated comprehensive synthesis is needed to delineate the disease burden. We searched PubMed, Embase, Scopus, Web of Science and Cochrane databases from inception to 18 February 2025, for studies reporting the incidence, prevalence or mortality of ALS in the general population. Pooled estimates with 95% CIs were calculated, and subgroup analyses were performed. Of 29\u2009110 articles initially screened, 142 were included. Global pooled incidence was 1.65 per 100\u2009000 person-years (95% CI 1.43 to 1.91), prevalence was 5.05 per 100\u2009000 population (95%\u2009CI 4.26 to 5.99) and mortality was 1.26 per 100\u2009000 person-years (95%\u2009CI 0.94 to 1.69). Both incidence rate ratio (IRR=0.74) and prevalence rate ratio (PRR=0.69) indicated significantly lower disease burden in females than in males. The burden of disease exhibited a marked age-dependent pattern, peaking at ages 70-79. Temporal trend analyses revealed a consistent increase in prevalence from 1963 to 1999\u2009onwards, while incidence peaked in 2014-2017. Geographically, incidence and prevalence were highest in Europe, North America and Oceania and lowest in Asia and South America. The disease burden was significantly higher in high-income countries compared with both upper-middle-income and lower-middle-income countries. This systematic review provides updated global ALS burden estimates, showing variations by sex, age, time and geography and underscoring the complex interplay of genetic, environmental and socioeconomic factors, with implications for health planning, resource allocation and etiological research.\n\nID: 42394962\nTitle: Decremental responses following repetitive nerve stimulation in spinal and bulbar muscular atrophy.\nAbstract: The presence of decremental responses following repetitive nerve stimulation (RNS) in amyotrophic lateral sclerosis (ALS) is well established. However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3\u00a0Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments.\n\nID: 42393482\nTitle: Diverging trends in motor neuron disease burden in China: an ageing-driven increase despite declining age-standardised rates - a GBD 2021 analysis.\nAbstract: Age-standardised rates of motor neuron disease (MND) have declined in many settings, yet the absolute burden continues to rise in ageing populations. Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations.\n\nID: 42387528\nTitle: Fidelity in the context of adapting a digital intervention for depression from an evidence-based in-person format in Vietnam.\nAbstract: Digital interventions have emerged as a promising way to better meet growing population mental health needs. Our team developed a digital depression intervention (VMood; smartphone app) in Vietnam. VMood is adapted from an evidence-based in-person intervention (SSM) developed in Canada and uses cognitive behaviour therapy (CBT) principles with remote coaching by non-specialist providers. Fidelity-adaptation is a major tension in implementation science. Fidelity is the degree an intervention is designed and delivered as intended. Conversely, adaptations are sometimes made for specific contexts. This paper aims to identify key elements of fidelity-adaptation - the degree VMood is consistent theoretically with the SSM intervention and practically with implementing digitally in the Vietnamese setting. This study uses Perez et al.'s modified version of Carroll et al.'s Implementation Fidelity Framework, focusing on Objective 1: Conceptualizing what intervention fidelity means in this specific context (across modes and cultures) and Objective 2: Conducting fidelity testing to identify key elements along the fidelity-adaptation continuum. Ethnographic data from team meetings explored essential components that must remain intact and necessary adaptations. Non-specialist providers and app users from Vietnam tested VMood. Experts familiar with CBT provided theoretical feedback. Interviews or focus groups were conducted with all participants to gain insights into the adaptive intervention. Qualitative data were analyzed using thematic content analysis. Participants agreed that VMood captures the essential theoretical components from SSM, noting certain elements of SSM (e.g., change in human contact to online) could not be replicated digitally. Participants also presented adaptation suggestions unique for the digital format to strengthen VMood's acceptability, including keeping the app simple by reducing the amount of text; incorporating more dynamic content (e.g., animations) to increase engagement; and including more culturally appropriate scenarios. Finally, key potential moderators to fidelity reported included quality of program delivery and participant responsiveness. Findings identified intervention specific elements of fidelity-adaptation and showed that VMood retained essential components of SSM while incorporating adaptations to support implementation within the Vietnamese context. With the global increase in digital health services adapted from in-person delivery, understanding how to balance fidelity with necessary adaptations is important both theoretically and practically.\n\nID: 42374626\nTitle: Microbiome and metabolites impact enteric and central nervous systems in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) has been linked to gastrointestinal symptoms and alterations in the gut microbiota. The enteric nervous system (ENS) coordinates intestinal function and sits at the host-microbe interface. The mechanisms by which luminal changes relay to the central nervous system (CNS), where motor neurons reside, have yet to be completely defined. In this narrative review, we first present evidence from ALS patient cohorts and preclinical models alongside mechanistic studies of infection, dysbiosis, and related neurodegenerative diseases to discuss how the microbiota and its metabolites may affect the ENS and CNS in ALS. Next, we propose a plausible mechanism of ALS pathogenesis through the gut-microbiome-brain axis. We further offer a summary of clinical trials that have studied the impacts of the microbiota on human ALS. Finally, we discuss future directions for studies of microbiota-ENS-CNS interactions in ALS. Better understanding of the dynamic interactions among the microbiota, microbial metabolites, neuroactive metabolites, and inflammation through the ENS/CNS in ALS will provide innovative insights into ALS prevention and treatment.\n\nID: 42373582\nTitle: Unravelling the Significance of Cystatin C and Bunina Bodies in Amyotrophic Lateral Sclerosis Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a fatal neurodegenerative disease primarily affecting motor neurons. Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies.\n\nID: 42367369\nTitle: Preparing Amyotrophic Lateral Sclerosis Clinics to Provide Longitudinal Care for Individuals Carrying ALS Risk Variants.\nAbstract: Emerging genetic therapies and the expansion of genetic testing are identifying individuals carrying amyotrophic lateral sclerosis (ALS) risk variants who would benefit from surveillance and early intervention. Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.\n\nID: 42365206\nTitle: Navigating the CBD: How Urban Risk Environment Shapes Daily Life for People Who Use Drugs in Edmonton's Central Business District.\nAbstract: Public drug use in urban central business districts (CBDs) presents an urgent public health challenge in Canada. People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170\u00a0h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected.\n\nID: 42360043\nTitle: Comparison of Proteomic Analysis of Cerebrospinal Fluid From Neurological Patients With and Without Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterised by progressive muscle weakness in both bulbar and extremity muscles, leading to a diverse clinical phenotype with motor and non-motor symptoms. Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.\n\nID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1\u03b2, \u03b3 interferon (IFN-\u03b3), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1\u03b2, IFN-\u03b3, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1\u03b2 and IFN-\u03b3 decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1\u03b2,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice. The underlying mechanism may be related to attenuating neuroinflammation via the modulation of microglial activation mediated by TREM2. \u76ee\u7684\uff1a\u57fa\u4e8e\u9ad3\u6837\u7ec6\u80de\u89e6\u53d1\u53d7\u4f532\uff08TREM2\uff09\u4ecb\u5bfc\u7684\u5c0f\u80f6\u8d28\u7ec6\u80de\u6d3b\u5316\u89c2\u5bdf\u7535\u9488\u201c\u8db3\u4e09\u91cc\u201d\u5bf9\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u6a21\u578b\u5c0f\u9f20\u795e\u7ecf\u708e\u75c7\u7684\u5f71\u54cd\u3002 \u65b9\u6cd5\uff1a\u5c0636\u53eaSPF\u7ea7\u96c4\u6027\u4eba\u7a81\u53d8\u578b\u8d85\u6c27\u5316\u7269\u6b67\u5316\u91761\uff08SOD1-G93A\uff09\u8f6c\u57fa\u56e0\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u6a21\u578b\u7ec4\u3001\u7535\u9488\u7ec4\u3001\u836f\u7269\u7ec4\uff0c\u6bcf\u7ec412\u53ea\uff1b\u9009\u53d612\u53ea\u540c\u7a9d\u91ce\u751f\u5c0f\u9f20\u4f5c\u4e3a\u5bf9\u7167\u7ec4\u3002\u7535\u9488\u7ec4\u4e8e\u201c\u8db3\u4e09\u91cc\u201d\u8fdb\u884c\u7535\u9488\u5e72\u9884\uff0c\u91c7\u7528\u65ad\u7eed\u6ce2\uff0c\u9891\u738715 Hz\uff0c\u6bcf\u6b2110 min\uff0c\u9694\u65e51\u6b21\uff0c\u6bcf\u54683\u6b21\uff0c\u51714\u5468\uff1b\u836f\u7269\u7ec4\u4e88\u5229\u9c81\u5511\u6eb6\u6db2\uff088 mg/kg\uff09\u704c\u80c3\uff0c\u6bcf\u65e51\u6b21\uff0c\u51714\u5468\u3002\u5e72\u9884\u7ed3\u675f\u540e\uff0c\u5e94\u7528\u8f6c\u68d2\u6d4b\u8bd5\u4e0e\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u8bc4\u4f30\u5404\u7ec4\u5c0f\u9f20\u884c\u4e3a\u5b66\uff0cHE\u67d3\u8272\u548c\u5c3c\u6c0f\u67d3\u8272\u89c2\u5bdf\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u5f62\u6001\uff0c\u514d\u75ab\u8367\u5149\u6cd5\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\uff0cWestern blot\u6cd5\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u7ec4\u7ec7\u767d\u7ec6\u80de\u4ecb\u7d20\uff08IL\uff09-1\u03b2\u3001\u03b3\u5e72\u6270\u7d20\uff08IFN-\u03b3\uff09\u3001IL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u7ec4\u7ec7\u5355\u7ec6\u80de\u60ac\u6db2CD86+\u548cCD206+\u7ec6\u80de\u6bd4\u4f8b\u3002 \u7ed3\u679c\uff1a\u4e0e\u5bf9\u7167\u7ec4\u6bd4\u8f83\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u6392\u5217\u7d0a\u4e71\uff0c\u51fa\u73b0\u6838\u56fa\u7f29\u3001\u80de\u4f53\u76b1\u7f29\u7b49\u73b0\u8c61\uff1b\u8f6c\u68d2\u6d4b\u8bd5\u6f5c\u4f0f\u671f\u548c\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u6389\u843d\u65f6\u95f4\u7f29\u77ed\uff0c\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u3001IFN-\u03b3\u3001IL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5355\u7ec6\u80de\u60ac\u6db2CD86+\u3001CD206+\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0c\u7535\u9488\u7ec4\u548c\u836f\u7269\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u6392\u5217\u8f83\u89c4\u6574\uff0c\u6838\u56fa\u7f29\u53ca\u5c3c\u6c0f\u5c0f\u4f53\u6eb6\u89e3\u4e22\u5931\u73b0\u8c61\u6539\u5584\uff0c\u795e\u7ecf\u5143\u7ed3\u6784\u5b8c\u6574\u6027\u63d0\u9ad8\uff1b\u8f6c\u68d2\u6d4b\u8bd5\u6f5c\u4f0f\u671f\u548c\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u6389\u843d\u65f6\u95f4\u5ef6\u957f\uff0c\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\u964d\u4f4e\uff0c\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u3001IFN-\u03b3\u86cb\u767d\u8868\u8fbe\u964d\u4f4e\uff0cIL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7CD86+\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e\uff0cCD206+\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8\uff08P<0.01\uff0cP<0.05\uff09\u3002\u4e0e\u836f\u7269\u7ec4\u6bd4\u8f83\uff0c\u7535\u9488\u7ec4\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0cIL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u964d\u4f4e\uff0cCD206+\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e\uff08P<0.05\uff09\u3002 \u7ed3\u8bba\uff1a\u7535\u9488\u201c\u8db3\u4e09\u91cc\u201d\u5bf9SOD1-G93A\u8f6c\u57fa\u56e0\u5c0f\u9f20\u8fd0\u52a8\u529f\u80fd\u5177\u6709\u4e00\u5b9a\u7684\u6539\u5584\u4f5c\u7528\uff0c\u5176\u4f5c\u7528\u673a\u5236\u53ef\u80fd\u4e3a\u8c03\u63a7TREM2\u4ecb\u5bfc\u7684\u5c0f\u80f6\u8d28\u7ec6\u80de\u6d3b\u5316\uff0c\u8fdb\u800c\u6539\u5584\u795e\u7ecf\u708e\u75c7\u3002.\n\nID: 42339846\nTitle: Single-O2ligation of hemoglobin links aerobic and anaerobic metabolism.\nAbstract: Oxygen (O2) binding and release by hemoglobin (Hb) are governed by cooperative interactions among its four subunits. During incremental workload exercise, femoral venous oxyhemoglobin (O2Hb) saturation exhibits a reproducible, momentary increase at the gas exchange threshold-coinciding with the inflection point of the in vivo O2 non-equilibrium curve (ONC). This suggests a transient shift in Hb's binding dynamics. We hypothesized that at this threshold, Hb tetramers carrying \u22641 bound O2 become predominant. In this state, the last bound O2 promotes further cooperative binding, but its release confers no cooperative advantage for unloading, biasing toward O2 rebinding. Using the O2 equilibrium curve models of Dash et al. (2016) and Adair, we computed the distribution of Hb's O2 ligation states across 12 pooled mean femoral venous blood samples from incremental workload cardiopulmonary exercise testing of five healthy male participants. At the gas exchange threshold-where the ONC inflects and flattens-tetramers with \u22641 O2 indeed dominated. This ligation-state distribution is consistent with Perrella et al.'s (1999) cryogenic resolution of native human Hb, which shows that carbon monoxide-ligated Hb tetramers peak at ~15-20% saturation, matching femoral venous ranges at the gas exchange threshold. Our results suggest that, at sufficiently low O\u2082Hb saturation, Hb may favor O\u2082 rebinding over cooperative unloading. We propose that glycolytic proton production and other Bohr effectors may counter this predicted binding bias supporting continued O\u2082 unloading. If confirmed, this mechanism unifies long-standing controversies in O2 transport physiology, framing the Hb-Bohr system as a proportional-integral controller of tissue oxygenation.\n\nID: 42334507\nTitle: Associations influencing quality of life in caregivers of patients with amyotrophic lateral sclerosis: a stress-process model approach.\nAbstract: Caring for patients with amyotrophic lateral sclerosis (ALS) involves demands that reduce caregivers' quality of life. Although caregiver burden and perceived social support was conceptualized as an independent correlate of quality of life rather than a factor operating primarily through caregiver burden. This study examined these associations within a stress-process framework in which perceived social support was conceptualized as an independent correlate rather than a buffering factor. This cross-sectional analytical study included 118 informal caregivers of patients with ALS. Primary stressors were defined as patient functional status (ALSFRS-R), caregiving duration, and communication difficulty. Caregiver burden (Zarit Burden Interview) was considered a secondary stressor. Physical and mental quality of life were assessed using the SF-12, and perceived social support was measured with the Multidimensional Scale of Perceived Social Support. Hierarchical regression analyses were performed to examine associations specified in the conceptual model while controlling for caregiver sociodemographic and socioeconomic variables. Additional mediation analyses were conducted to examine whether caregiver burden mediated the relationship between perceived social support and quality of life. Poorer patient functional status was significantly associated with higher caregiver burden, whereas communication difficulty showed a positive but non-significant association after adjustment for caregiver characteristics. Caregiver burden showed negative associations with both physical and mental quality of life. Perceived social support remained positively associated with quality of life after adjustment for caregiver burden and contributed additional explained variance in the models. Mediation analyses showed no evidence that caregiver burden mediated the association between perceived social support and either physical or mental quality of life. The findings are consistent with a stress-process framework in ALS caregiving, in which caregiver burden represents a central factor statistically associated with both caregiving stressors and quality of life, while perceived social support shows an independent association with quality of life. These findings suggest that both caregiver burden and perceived psychosocial resources may be relevant to caregiver well-being, although causal and intervention-related implications require further investigation. Caring for a person with amyotrophic lateral sclerosis (ALS) is physically and emotionally demanding, and many caregivers experience reduced quality of life. Previous studies have examined caregiver burden and social support separately, but it is not well understood how these factors work together to influence caregivers\u2019 well-being. This study examines how disease-related challenges, caregiver burden, and perceived social support are connected, and how these factors jointly affect the physical and mental quality of life of ALS caregivers. The study tests a conceptual model proposing that caregiving challenges increase caregiver burden, which in turn affects quality of life, while perceived social support contributes directly to quality of life rather than simply reducing stress. Worse patient functioning and communication difficulties were linked to higher caregiver burden. Higher burden was associated with poorer physical and mental quality of life. Perceived social support remained positively related to quality of life even after accounting for caregiver burden. These findings suggest that improving social support and reducing caregiver burden are both important for maintaining quality of life among ALS caregivers.\n\nID: 42315356\nTitle: Strategic Amyotrophic Lateral Sclerosis Australia-Systems Genomics Consortium (SALSA-SGC): cohort profile.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative motor neuron disease (MND) with heterogeneity in disease onset, progression and treatment response. The Strategic ALS Australia-Systems Genomics Consortium (SALSA-SGC) was established in recognition of the need for large data sets of clinical data matched with biological samples to enable and foster ALS research and better understanding of aetiology and biological mechanisms. SALSA-SGC brought together the major Australian MND clinics to set up sustainable infrastructure that could facilitate long-term human ALS research and clinical trials nationally and internationally. Between April 2016 and December 2024, SALSA-SGC recruited 1813 participants, including 1386 ALS/MND cases, 388 controls and 39 others (asymptomatic relatives and ALS mimics). Clinical data and biospecimens are available for 1333 and 1189 ALS cases, respectively, with longitudinal data spanning 4442 total clinic visits and 3201 samples. An open-access online data explorer showcases collected datasets. Detailed clinical and questionnaire data allow an in-depth description of the cohort, informing clinical and health policy research. Screening for known ALS large-effect risk variants identified 125 mutation carriers (11.5% from N=1059), including 70 with C9orf72 expansions. Single Nucleotide Polymorphism (SNP)-array data (N=1088 cases; N=244 controls) have supported multiple published studies. SALSA-SGC resources are actively used by national and international researchers. Ongoing efforts aim to expand recruitment into regional Australia and enhance sample processing for cell-based studies. The SALSA-SGC resource is accessible by researchers under agreements governed by participant consent, human ethics committee guidelines and agreed use of data and samples.\n\nID: 42304913\nTitle: Nicotine Versus Non-Nicotine Constituents in Neurodegenerative Risk: Evidence from Multivariable Mendelian Randomization.\nAbstract: Nicotine has complex neuropharmacological actions through nicotinic acetylcholine receptors, but its independent role in neurodegenerative diseases remains unclear because tobacco smoke contains many non-nicotine toxicants. This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50). Exposure to nicotine can increase the risks of AD, while conferring protective effects against tremor and EC. Furthermore, exposure to non-nicotine tobacco constituents acts as a risk factor for the incidence of EC.\n\nID: 42297981\nTitle: Plasma proteomic signatures of cellular aging predict human disease.\nAbstract: Aging is asynchronous across cells and organs. Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.\n\nID: 42288074\nTitle: Mean airway pressure as the missing link in CPR physiology: A prehospital comparison of manual and mechanical chest compressions.\nAbstract: The impact of manual versus mechanical chest compressions on mean airway pressure (mPAW) during cardiopulmonary resuscitation (CPR) is poorly understood. This exploratory pilot study assessed intratracheal airway pressures during prehospital CPR in out-of-hospital cardiac arrest (OHCA). Adult OHCA patients treated by the prehospital Medical Emergency Team of the Ghent University Hospital (Belgium) were prospectively enrolled. Intratracheal pressure was recorded immediately after intubation, mPAW was calculated for both the first and last minutes of advanced life support (ALS). The results were compared between mechanical compressions using the Stryker LUCAS3\u00ae device and manual chest compressions (with chest compression feedback). Nineteen patients were included (manual n\u00a0=\u00a010; mechanical n\u00a0=\u00a09). Initial median mPAW was low (7.74\u00a0mbar) and showed a slight increase over time. Mechanical compressions generated higher early mPAW than manual compressions (8.96 vs. 6.54\u00a0mbar). mPAW increased over time with manual compressions and decreased with mechanical compressions. Patients who achieved return of spontaneous circulation (ROSC) showed higher mPAW, though this difference was not statistically significant. Prehospital mPAW values were substantially lower than those reported in previous ED-based studies. While airway pressure patterns differed between compression modalities, overall pressures were similar. These findings highlight complex airway mechanics during CPR and support further research into whether higher airway pressures could improve airway patency, oxygenation, and hemodynamics in selected OHCA patients.\n\nID: 42287763\nTitle: Opportunistic salpingectomy during non-gynecologic surgery: Canadian surgeons' experience, barriers and facilitators.\nAbstract: Opportunistic salpingectomy during concurrent abdominopelvic surgery has been shown to significantly reduce ovarian cancer risk. Uptake by non-gynecologic surgeons could increase population impact. We conducted a national survey of general and urologic surgeons using Michie et al.'s implementation framework of Capability, Motivation, Opportunity-Behaviour to understand understand current experience with opportunistic salpingectomy, and facilitators and barriers to adoption. An online survey was administered to Canadian general and urologic surgeons and postgraduate trainees from January-June 2024. A multivariable logistic regression model assessed relationship between demographic factors and motivation to adopt opportunistic salpingectomy. 269 surveys were completed by 226 general surgeons and 43 urologists. Although 88% reported motivation to perform opportunistic salpingectomy for cancer prevention, practice duration \u226521\u00a0years and province of practice were associated with decreased motivation. Only 44% were aware of recommendations endorsing the procedure, and 19% had performed it. Commonly reported barriers to adoption were Capability (consenting patients regarding permanent contraception and ovarian function, and intraoperative technique/complications), and Opportunity (reimbursement). A surgical video was the preferred method to learn salpingectomy by 94%, and patient consent handouts and intraoperative training by a gynecologist were facilitators. Most (92%) stated that opportunistic salpingectomy training should be offered to postgraduate trainees. Most general and urologic surgeons in Canada were unaware of and have not performed opportunistic salpingectomy but were motivated to offer it. Providing consent resources and training opportunities with gynecologist support, and addressing cultural and regulatory factors may improve uptake by surgeons and decrease ovarian cancer incidence.\n\nID: 42274954\nTitle: Complications after sentinel node biopsy and inguinal lymph node dissection in penile cancer: a Danish national cohort study.\nAbstract: Sentinel node biopsy (SNB) and inguinal lymph node dissection (ILND) are central to penile cancer management, but ILND especially carries substantial morbidity. This nationwide study explores the extent and risk factors of postoperative complications after inguinal lymph node surgery in Danish penile cancer patients. We conducted a retrospective cohort study of penile cancer patients diagnosed in Denmark 2013-2025. Surgical procedures, pathological outcomes, and complications were extracted from medical records. Univariable and multivariable logistic regression with multiple imputation was used to assess predictors of complications. Among 745 patients, 717 underwent 1348 SNB procedures and 184 underwent 241 ILND procedures. Postoperative morbidity increased substantially with procedural extent, with complications occurring after 9% of SNB procedures and after 31% of ILND procedures. Lymphoedema developed in 47% of patients following ILND versus 9% following SNB. Increasing lymph node yield independently predicted overall complications within both SNB and ILND cohorts and was additionally associated with wound infection following SNB. For lymphoedema, ILND carried five- to nine-fold higher odds compared with SNB, while higher BMI independently predicted lymphoedema risk (OR 1.07 per kg/m2, p\u2009=\u20090.002). Complications increase markedly with procedure extent. Increasing lymph node yield was associated with wound infection, while lymphoedema is primarily determined by procedure type. Poor predictive ability of patient characteristics limits pre-operative risk stratification.\n\nID: 42272352\nTitle: Impact of treatment burden on medication adherence and quality of life in amyotrophic lateral sclerosis: a prospective multicentre study.\nAbstract: Patients with amyotrophic lateral sclerosis (ALS) face substantial barriers to medication adherence as disease progression necessitates complex drug formulation adjustments, such as crushing tablets, mixing with liquids, or delivering via feeding tubes. These modifications may not only increase the time and effort required but could also impact drug efficacy and safety. To evaluate the prevalence and the impact of treatment burden on medication adherence and patient-reported quality of life (QoL) in ALS. This prospective multicenter study enrolled ALS patients across three Italian reference centers, with assessments at baseline, 6, and 12\u2009months. Key measures included the Multimorbidity Treatment Burden Questionnaire (MTBQ), ALSFRS-R, DYALS (dysphagia), Morisky Medication Adherence Scale, SSS-8 (somatic symptoms), INQoL (QoL), SWAMECO (swallowing/medication difficulties), alongside comorbidities and current therapies. Associations between treatment burden, QoL, and adherence were analyzed using multivariable models. A total of 114 consecutive ALS patients were enrolled. Clinically significant treatment burden was observed in 69.3% of patients, with over half reporting moderate-to-high levels according to the MTBQ classification. Elevated burden was independently related to greater somatic symptom severity and formulation modification needs. Moreover, higher burden associated with poorer QoL and diminished adherence after confounder adjustment. Longitudinally, patients experiencing worsening burden over 1 year showed accelerated QoL decline compared to those remaining stable, though adherence trajectories were unaffected. Treatment burden, particularly driven by drug formulation complexities and somatic symptoms, emerges as a pivotal, modifiable determinant of adherence and QoL in ALS. Targeted interventions to alleviate modifiable burden components hold promise for optimizing clinical outcomes and enhancing patient-centred care.\n\nID: 42265764\nTitle: Estimation of human brain fluid clearance using intrathecal imaging contrast agents.\nAbstract: Extra-vascular brain fluid dynamics, including exchange through glymphatic and meningeal lymphatic pathways, has been proposed essential for waste clearance and solute transport in the central nervous system. Although animal studies provide evidence for these pathways' role in clearing neurotoxic proteins and distributing solutes delivered to cerebrospinal fluid (CSF), translation to humans is limited. Quantitative, in vivo measures of inter-individual variability in brain fluid clearance in clinical populations are largely lacking. This study investigated the feasibility of estimating brain fluid clearance indices using intrathecal imaging contrast agents. In a prospective and observational study, iodixanol (Visipaque, GE Healthcare, USA, 270\u2009mg I/mL, 3\u2009mL) was administered intrathecally as a CSF tracer and its clearance from CSF to blood was quantified using population pharmacokinetic modeling. Intracranial tracer enrichment in CSF was assessed by its radiodensity (Hounsfield units) within predefined regions of interest (cisterna magna, Sylvian fissure and vertex) on cranial computed tomography (CT) performed 2-, 4- and 24-hours post-injection. These results were compared with brain fluid clearance indices derived from a separate population pharmacokinetic model using intrathecal gadobutrol (Gadovist, Bayer AG, GE, 1.0\u2009mmol/mL, 0.50\u2009mL), with its enrichment in CSF defined as gadobutrol-induced T1 signal increase from baseline within corresponding subarachnoid spaces on magnetic resonance imaging (MRI). The study included 52 subjects receiving intrathecal iodixanol and 45 individuals receiving intrathecal gadobutrol. Marked inter-individual variability was observed in brain fluid clearance to blood for both contrast agents, as well as their distribution in CSF as assessed by CT and MRI. Brain fluid clearance from iodixanol and gadobutrol were significantly correlated. Notably, clearance indices showed stronger correlations with intracranial distribution in CSF for gadobutrol-derived MRI metrics than for iodixanol-derived CT metrics. These findings demonstrate the feasibility of estimating brain fluid clearance in humans using intrathecal imaging contrast agents as CSF tracers. Brain fluid clearance capacity exhibits pronounced inter-individual variability and correlates with the degree of contrast enrichment in intracranial subarachnoid spaces, particularly when assessed by MRI. The results underscore the importance of individualized assessment of brain fluid clearance, with implications for studies on pathogenetic mechanisms of neurodegeneration and optimization of intrathecal drug delivery.\n\nID: 42265364\nTitle: The asymmetric list shift effect - flexible adaptation to new context demands?\nAbstract: The list-wide proportion congruency effect describes how the congruency effect varies depending on the frequency of incongruent trials within a block. Specifically, the congruency effect is larger in mostly congruent (MC) blocks compared to mostly incongruent (MI) blocks. Research has shown that adaptation to these blocks does not change symmetrically when transitioning between them: moving from MC to MI leads to a rapid decrease in the congruency effect while transitioning from MI to MC results in little or no increase (Abrahamse et al., 2013). We aimed to investigate this asymmetric list shift (ALS) effect in a within-participants design where all participants experienced both transitions (MC-MI and MI-MC). Throughout Experiments 1-3 using a color-word Stroop task, we identified various forms of practice - including trial-type, stimulus-specific learning, general RT decrease, and a decrease in congruency effects over time (see Schmidt, 2016) - that can either facilitate or obscure the ALS effect, depending on the order in which participants experienced the transitions. In Experiment 4, using a face-name version of the Stroop task, where we minimized practice-related confounding factors by employing more complex stimuli and used a new stimulus set in the second transition, an ALS effect was observed regardless of the order of transition and for frequency-unbiased (i.e., 50% congruent) items. The role of practice effects and implications for the (in)-flexibility of control adaptations will be discussed.\n\nID: 42264735\nTitle: Herbicide metabolism and EPSPS Pro-106-Ser substitution confer multiple resistance in Chenopodium spp. from Southern Spain.\nAbstract: Long-term herbicide programs in Mediterranean perennial systems have imposed sustained selection pressure on weed populations, promoting the evolution of multiple resistance. We investigated resistance mechanisms in Chenopodium album (Ca) and C. vulvaria (Cv) from southern Spain following more than two decades of glyphosate-based management. We aimed to (i) confirm resistance to atrazine, tribenuron-methyl (TM), glyphosate, and 2,4-D; (ii) distinguish between target-site and metabolic resistance; and (iii) characterize the biochemical and molecular basis of cross- and multiple-herbicide resistance. Screening assays revealed high survival (78-100%) of resistant (R) populations to acetolactate synthase (ALS)-, photosystem II (PSII)-, auxinic-, and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS)-inhibiting herbicides. Dose-response assays confirmed resistance, with resistance indices (RI) of 6.7 and 5.1 for atrazine, 19.0 and 17.3 for TM, 7.0 and 13.9 for glyphosate, and 6.0 and 6.9 for 2,4-D in CaR and CvR, respectively. Radiolabelled and analytical metabolism assays demonstrated enhanced herbicide metabolism in R populations: atrazine (94-95% vs. 13-16% in S), TM (68-69% vs. 24-25%), 2,4-D (64-65% vs. 2-4%), and glyphosate (39-43% vs. 8-9%). Malathion partially reversed resistance to atrazine, TM, and 2,4-D, supporting cytochrome P450 (CYP450) involvement. In contrast, glyphosate metabolism was independent of CYP450 or glutathione S-transferases inhibition. Biochemical assays showed no differences in PSII or ALS sensitivity (I\u2085\u2080 RI\u00a0\u2248\u00a01), whereas EPSPS inhibition assays revealed a tenfold increase in I\u2085\u2080 in CvR. Sequencing identified a Pro-106-Ser substitution in EPSPS exclusively in CvR. Enhanced metabolism predominates in the R Chenopodium spp. populations, with coexistence of metabolic and target-site mechanisms in CvR, increasing the risk of further cross-resistance under continued herbicide reliance.\n\nID: 42251967\nTitle: PBMC DEG/miRNA biomarkers of TDP-43 pathology in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) lacks reliable, disease-specific, and minimally invasive biomarkers, representing a major barrier to early diagnosis and patient stratification. The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS.\n\nID: 42247653\nTitle: Drivers of Rising Prevalence in Major Motor Neurodegenerative Diseases: Temporal Trends in Sweden and France (2003-2022).\nAbstract: The prevalence of Parkinson disease (PD), multiple sclerosis (MS), and motor neuron diseases (MNDs) is rising globally. However, it is unclear to what degree this is related to an increase in incidence or to improved survival after diagnosis. We performed 2 nationwide, population-based, retrospective cohort studies, including all individuals living in Sweden between 2001 and 2016 and living in France between 2009 and 2022, respectively. Pooled mixed-effects regression models, with country as a random effect, were used to determine temporal trends in prevalence, crude and age-standardized and sex-standardized incidence, and age and life expectancy at diagnosis. Annualized prevalence of PD, MS, and MNDs increased significantly between 2003 and 2022 in the pooled model (PD: prevalence ratio [PR] per year = 1.014, p < 0.001; MS: PR = 1.029, p < 0.001; MND: PR = 1.028, p < 0.001). While the crude incidence of both PD and MS remained nearly stable over time (PD: incidence rate ratio [IRR] per year = 0.998, p < 0.001; MS: IRR = 0.992, p < 0.001), the standardized incidence showed a more marked decrease for PD (IRR = 0.986, p < 0.001) while remaining almost unchanged for MS (IRR = 0.995, p < 0.001). For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001). Life expectancy at diagnosis of PD increased between 2003 and 2013 (+0.95 months per calendar year, p < 0.001) and then decreased between 2013 and 2022 (-1.20 months, p = 0.002), while it increased significantly over the entire study period for MS (+2.35 months, p < 0.001) and MNDs (+0.34 months, p = 0.01). These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence. Depending on the mechanism that drives prevalence, whether increased incidence reflecting changing risk factor exposures, improved survival due to therapeutic advances, or demographic aging of the population, inferences about underlying causes differ substantially between PD, MS, and MNDs, with direct implications for health care planning and etiologic research.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42397462\nTitle: A case study of comprehensive association analysis and risk prediction of amyotrophic lateral sclerosis in a Chinese population.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease with significant genetic heterogeneity. While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients.\n\nID: 42386657\nTitle: The SQSTM1 L341V Variant Associated With Sporadic ALS Promotes the Accumulation of Enlarged Ubiquitin-Positive SQSTM1 Bodies.\nAbstract: SQSTM1 is one of the causative genes of neurodegenerative disorders, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The SQSTM1 protein regulates the degradation of polyubiquitinated proteins and autophagosome formation through its interaction with microtubule-associated protein light chain 3 (MAP1LC3/LC3). However, the molecular mechanisms by which SQSTM1-LC3 binding regulates the autophagy-endolysosomal system (APELS) remain unclear. To elucidate the spatiotemporal role of SQSTM1, we transiently expressed wild-type SQSTM1 or missense mutants carrying mutations in the LC3-interacting region (LIR), fused with the photoconvertible fluorescent protein Dendra2. Live-cell fluorescence imaging and co-localization analyses with markers of the APELS were then performed. Particle analysis of photoconverted or non-photoconverted SQSTM1-positive structures in live cells revealed that the pathogenic L341V variant formed larger structures than the wild-type. Co-localization analyses further showed that both the L341V and artificial LIR3A mutants accumulated in large ubiquitin-positive structures, likely due to impaired localization to autophagosomes. These results suggest that mutations within the LIR differentially affect autophagosome formation and cargo degradation within APELS-related compartments, highlighting the importance of SQSTM1 structural integrity in ALS/FTD pathogenesis.\n\nID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\n\nID: 42371122\nTitle: Quantification of amyotrophic lateral sclerosis (ALS) disease accumulation with T1-weighted high-resolution magnetic resonance imaging: validation in an independent cohort.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a progressive neuromuscular disease with multifaceted phenotypic presentation thus obstructing objective disease staging. The D50 disease progression model is a framework to comprehensively dissect biomarker-signals towards their relevance regarding disease accumulation/phase (rD50), or disease aggressiveness (D50). Based on previous findings using 1.5-Tesla Magnetic-Resonance-Imaging (MRI), this study hypothesized that high-resolution MRI markers of Grey-Matter (GM) structural integrity would enable quantification of disease accumulation, independent of aggressiveness. A separate cohort of 75 patients with ALS and 73 Healthy Controls (HC) underwent T1-weighted 3-Tesla MRI. Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p\u2009<\u20090.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p\u2009<\u20090.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p\u2009<\u20090.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results. These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness. This principle was validated across different scanners and field strengths, supporting its application for objective and non-invasive staging of patients with ALS, whereby true longitudinal studies are necessary.\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42265995\nTitle: Two Patients With Juvenile-Onset, Rapidly Progressive Amyotrophic Lateral Sclerosis Associated With an SOD1 Variant (p.Asp125Gly) With Incomplete Penetrance.\nAbstract: Amyotrophic lateral sclerosis (ALS) patients are rarely encountered before age 25\u2009years, often associated with genetic variants. SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies.\n\nID: 42223334\nTitle: Distinct UNC13A Haplotype Blocks Define Disease Severity and Survival in Chinese Amyotrophic Lateral Sclerosis.\nAbstract: UNC13A is a genetic modifier of amyotrophic lateral sclerosis (ALS) in European populations, but its role in Chinese patients remains incompletely characterized. We investigated the spectrum of UNC13A variation and its impact on disease risk and progression in a Chinese ALS cohort. We performed an integrated genetic analysis of 1,533 Chinese ALS patients and 1,405 controls, including rare variant burden testing, genome-wide survival analysis, haplotype mapping, and conditional analyses. An integrated clinical-genetic prognostic score was developed and validated. Rare deleterious UNC13A variants were not associated with ALS risk. We identified two independent haplotype blocks with distinct clinical impacts. Block 1 (tagged by rs75421007) was associated with reduced baseline muscle strength (p\u2009=\u20090.030), while Block 2 (tagged by rs78549703), a brain-specific splicing QTL, was the primary driver of survival heterogeneity. The European variant rs12608932 showed a survival association in single-marker analysis (p\u2009=\u20090.024), but conditional analyses revealed its effect was not independent of Block 2. An integrated prognostic score combining clinical factors and Block 2 haplotype stratified patients into low-, intermediate-, and high-risk groups (median survival: 52.6, 37.1, and 32.0\u2009months; p\u2009<\u20090.001), with decision curve analysis confirming clinical utility. This study delineates UNC13A genetic architecture in Chinese ALS, identifying two independent haplotype blocks that differentially influence disease severity and survival. The Block 2 haplotype, which includes a brain sQTL, is a major determinant of survival heterogeneity and may inform patient stratification in future studies.\n\nID: 42222887\nTitle: Multimodal analysis of cell-free DNA identifies epigenetic biomarkers for amyotrophic lateral sclerosis diagnosis and progression.\nAbstract: The role of the epigenome in age-related neurodegenerative disorders remains understudied. Here, we analyzed circulating cell-free DNA (cfDNA) from blood to detect methylation changes as a liquid biopsy for Amyotrophic Lateral Sclerosis (ALS). Our study included 20 patients with sporadic ALS, 10 patients with C9orf72-associated ALS, 10 asymptomatic carriers of the C9orf72 repeat expansion mutation, and 21 nondisease control individuals. Following targeted enzymatic methyl-sequencing (EM-seq) of approximately 4 million CpG sites, we detected numerous differentially methylated genes, including several implicated in ALS disease risk and pathogenesis. By integrating multiple epigenetic features, we delineated a distinct epigenetic signature, which achieved an average area under the curve (AUC) of 0.91 \u00b1 0.10 upon receiver operator characteristic (ROC) analysis, which enabled detection of approximately 70% of patients with ALS with close to 100% specificity. Furthermore, we also identified a set of genes whose methylation status significantly correlated with clinical disease progression and cerebrospinal fluid (CSF) neurofilament levels. Our results reveal the potential of cfDNA-based biomarkers to accurately diagnose ALS and potentially predict disease progression.\n\nID: 42212756\nTitle: 5-Hydroxytryptamine Distribution Alteration in Both Neuron and Synapse of Tg(SOD1*G93A)1gur Mice: A Potential Intervention Candidate Strategy for Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease; the precise pathogenesis of sporadic ALS (sALS) has not yet been elucidated up to now. Previous studies revealed that the abnormal alterations of some non-motor neurons (non-MN) were a potential pathogenesis of sALS. Therefore, this study aims to search the potential evidences of non-MN in the pathogenesis of ALS via exploring potential relationships between 5-hydroxytryptamine (5-HT) neurons and the development of ALS. We employed fluorescent immunohistochemistry to investigate the altered distribution patterns of 5-HT and tryptophan hydroxylase 2 in the spinal cord and brainstem of Tg(SOD1*G93A)1Gur (TG) and wild-type (WT) mice. Additionally, we used western blot to analyze the expression levels of 5-hydroxytryptamine receptor 1A (5-HTR1A) and 5-HTR2A. Our findings revealed that 5-HT synapses were primarily distributed in the funiculus lateralis, anterior horn, posterior horn, central lateral column, and the area around the central canal of cervical, thoracic, and lumbar segments, and raphe nucleus as well as lateral paragigantocellular nucleus, and gradually reduced following age increase in WT mice. However, 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem gradually increased following the progression of disease and presented a significantly negative correlation between the increased distribution of 5-HT synapses and neurons and the reduction of neural cell number (positively correlated with the increase in neural cell death) at the onset and/or progression stage of TG mice. 5-HTR1A significantly increased, while 5-HTR2A significantly decreased at the onset stage of TG mice. Our study speculated that the distribution changes of 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem play a potential protective role in the pathogenesis of sALS through a compensatory 5-HT increase.\n\nID: 42207242\nTitle: Anchoring ALS Prognosis: Neurofilament Light Chain Outperforms Inflammatory, Metabolic, and CNS Barrier Biomarkers in the METABALS Cohort.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rapidly progressive and fatal neurodegenerative disorder with marked biological heterogeneity. Despite extensive research, reliable prognostic biomarkers remain limited, with neurofilament light chain (NfL) being the only marker increasingly implemented in clinical practice. The objective of this study is to assess and compare the prognostic value of NfL, circulating markers of central nervous system (CNS) barrier dysfunction, inflammatory mediators, kynurenine pathway metabolites, and global metabolomic profiles in patients with ALS. Seventy-two patients with ALS from the prospective multicenter METABALS cohort were included. Serum, cerebrospinal fluid (CSF), and urine samples were collected at diagnosis. NfL concentrations, markers of blood-brain and blood-spinal cord barrier permeability (albumin quotient, S100B, neuron-specific enolase [NSE]), 48 inflammatory mediators, kynurenine pathway metabolites, and untargeted metabolomic profiles were measured. Associations with clinical features, disease progression, and survival were investigated using univariate analyses and multivariate models. Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival. Higher serum NfL concentrations at diagnosis predicted shorter survival (ROC AUC\u2009=\u20090.86). In all multivariate and multi-block models, serum NfL was the only biomarker independently associated with survival. Markers of CNS barrier integrity, inflammatory mediators, and metabolomic signatures showed limited prognostic value but provided insights into metabolic remodeling and barrier dysfunction. In this integrated multi-omics study, serum NfL clearly outperformed inflammatory, metabolic, and CNS barrier markers as a prognostic biomarker in ALS, supporting its central role in clinical stratification while complementary biological markers highlighted several relevant pathophysiological mechanisms.\n\nID: 42205021\nTitle: APOE \u03b54 Allele is Associated with Cognitive Impairment in Chinese Sporadic ALS: A Retrospective Cohort Study.\nAbstract: To evaluate the effects of apolipoprotein E (APOE) genotype and serum APOE levels on cognitive and motor phenotypes in Chinese patients with sporadic amyotrophic lateral sclerosis (ALS). APOE genotypes were determined in 289 patients with sporadic ALS, and serum APOE levels were measured in a subset of 222 patients. Cognitive function was assessed using the Edinburgh Cognitive and Behavioural ALS Screen. We examined the association of APOE genotype and serum levels with age at onset, site of onset, disease progression rate (DPR), time to generalization of symptoms (TTG), and cognitive performance. No significant differences were observed in sex, age at onset, site of onset, DPR, or TTG among patients with different APOE genotypes. Similarly, serum APOE levels did not correlate with these clinical variables. However, the APOE-\u03b54 allele was associated with lower ALS-specific cognitive scores, particularly in the domain of verbal fluency. Our study provides preliminary evidence linking the APOE-\u03b54 allele to cognitive impairment, particularly in language fluency, among Chinese patients with ALS. These findings support the hypothesis that APOE genotype contributes to ALS etiology and suggest its role in shaping distinct cognitive phenotypes in the disease.\n\nID: 42195033\nTitle: From Mutation to Manifestation: Penetrance in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by progressive loss of motor neurons in the brain and spinal cord. While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.\n\nID: 42194069\nTitle: Oxidative-Nitrosative Stress and Routine Biochemical Parameters in Amyotrophic Lateral Sclerosis: Associations with Clinical Status and Disease Duration-A Pilot Study.\nAbstract: This pilot study examined whether oxidative-nitrosative stress is associated with clinical status in amyotrophic lateral sclerosis (ALS). We analyzed associations between plasma markers of oxidative-nitrosative imbalance and ALSFRS-R, disease duration, survival, and routine biochemical parameters. Twenty-nine ALS patients fulfilling the Gold Coast diagnostic criteria were enrolled. Plasma levels of 3-nitrotyrosine (3-NT), 8-oxo-2'-deoxyguanosine (8-oxodG), malondialdehyde (MDA), glutathione (GSH), non-protein thiols (NP-SH), and non-protein disulfides (NP-SS-NP), as well as creatinine, urea, uric acid and BMI, were measured. Associations with ALSFRS-R and disease duration were evaluated using non-parametric correlation analyses and second-order polynomial regression (adjusted R2), while survival was explored using Kaplan-Meier analysis and multivariable Cox regression. Given the modest sample, we considered statistical power and applied Benjamini-Hochberg false discovery rate (FDR) correction within marker families. At the uncorrected significance level, 3-NT showed a positive correlation with ALSFRS-R and a negative correlation with disease duration, and NP-SH correlated negatively with disease duration; however, these associations did not remain significant after FDR correction (FDR-adjusted p \u2265 0.099). Other oxidative-nitrosative markers and biochemical parameters showed no robust relationships with clinical measures. In Cox models, 3-NT was not significantly associated with survival (HR 3.44 per 1 nM, 95% CI 0.25-47.97, p = 0.358), whereas older age predicted higher mortality (HR 1.05 per year, 95% CI 1.00-1.10, p = 0.036). 3-NT and NP-SH exhibited the strongest trends among the investigated markers, but their clinical associations in this small cross-sectional cohort remain exploratory and require confirmation in larger longitudinal studies.\n\nID: 42191932\nTitle: Motor neuron disease in Africa: a critical appraisal of the literature.\nAbstract: Motor neuron disease (MND) refers to a group of neurodegenerative diseases that cause motor neuron degeneration and death. The most common subtype, amyotrophic lateral sclerosis (ALS), is characterized by both upper and lower motor neuron impairment, which can manifest clinically in the bulbar region or asymmetrically in a limb. Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care. We share our perspective on how the ALS Africa Network is coordinating a shift in the African MND landscape to improve patient care.\n\nID: 42183197\nTitle: Classical HLA class II associations with ALS in Kuwait reveal a DR7-DQ2.2 risk haplotype.\nAbstract: Genome-wide association studies have implicated the human leukocyte antigen/major histocompatibility complex (HLA/MHC) region in amyotrophic lateral sclerosis (ALS) susceptibility, and immune dysregulation is increasingly recognised as a modifier of disease course. High-resolution HLA data for ALS remain confined to European and East Asian ancestries. We tested whether classical HLA class I and class II variation contributes to ALS susceptibility in a Kuwaiti cohort. We analysed 38 unrelated ALS cases (mean age, 57.4 years; 63.2% male) and 150 population-matched controls (mean age, 57.0 years) from Kuwait. HLA-A, -B, -C, -DRB1, -DQA1, and -DQB1 alleles were typed at two-field resolution using HLA-HD from next-generation sequencing (NGS) data. Allele, haplotype, and amino-acid residue associations were tested in BIGDAWG with locus-specific Bonferroni correction, with additional across-locus sensitivity analysis. Significant class II residues were mapped onto AlphaFold 3 structural models and interpreted alongside published class II crystal structures. No class I allele, haplotype, or residue remained significant after correction. In class II, DQA1*02:01 [odds ratio (OR) = 3.18, 95% confidence interval (CI) 1.67 to 5.95, p c = 0.0007], DRB1*07:01 (OR\u00a0=\u00a03.00, 95% CI: 1.58-5.59, p c = 0.001), and DQB1*02:02 (OR\u00a0=\u00a02.48, 95% CI: 1.28-4.69, p c = 0.03) were enriched in cases. The extended haplotype DQA1*02:01~DQB1*02:02~DRB1*07:01 (DR7-DQ2.2) conferred increased odds of ALS (OR\u00a0=\u00a03.11, 95% CI: 1.53-6.19, p c = 0.002). Amino-acid residue analysis identified convergent risk positions in DQ\u03b11 (positions 47, 52, and 54; OR\u00a0=\u00a03.18, p c = 0.006) and DR\u03b21 (positions 11, 13, 14, 25, and 30; OR\u00a0=\u00a02.84, p c = 0.03) that map to the peptide-binding groove and correspond to the defining motifs of DQA1*02:01 and DRB1*07:01. Using high-resolution NGS-based HLA typing in a Kuwaiti cohort, we identified a class II risk signal for ALS centred on the DR7-DQ2.2 haplotype with convergent residue-level support in the peptide-binding domains. These findings support a contribution of class II-restricted antigen presentation to ALS susceptibility and warrant functional validation and replication in larger, independent Middle Eastern cohorts.\n\nID: 42178739\nTitle: Proteomic Analysis of Corpora Amylacea Extracted From Post-mortem Brain of MAiD-end-of-life Sporadic ALS Patients.\nAbstract: Corpora amylacea (CA) are starch-like inclusions that accumulate in the central nervous system (CNS) with aging and are enriched in neurodegenerative conditions, including amyotrophic lateral sclerosis (ALS). Although often regarded as waste reservoirs, their cellular origins, molecular composition, and pathological significance remain poorly understood. Here, we performed an unbiased proteomic analysis of purified CAs isolated from post-mortem brains of sporadic ALS patients and controls. In-depth mass spectrometry identified 4,470 proteins, of which 658 were quantified, revealing distinct ALS-specific proteomic signatures. Enriched proteins included markers of cytoskeletal remodeling, mitochondrial dysfunction, and proteostasis disruption, as well as known ALS-associated proteins such as TDP-43 and neurofilament proteins. These findings demonstrate that CAs serve as reservoirs of dysfunctional, disease-relevant proteins and capture key pathological processes in ALS. By applying an unbiased proteomic approach to purified CAs, this study provides the first comprehensive map of their protein content in ALS, supporting their potential as biomarker sources and as a source of mechanistic insights into neurodegeneration. Unbiased analyses of CAs in the context of ALS have yet to be undertaken. This study provides the first proteomic profiling of purified CAs, isolated from ALS patient brains using biochemical methods, revealing that CAs harbor disease-relevant proteins implicated in sporadic ALS. By demonstrating that CAs act as reservoirs of dysfunctional proteins related to metabolism, cytoskeletal organization, and proteostasis, our findings highlight their potential as a novel source of ALS-specific mechanistic insight into disease pathology.\n\nID: 42171861\nTitle: TDP-43 Acetylation at the Neuroimmune Interface: A Hypothesis-Driven Framework for Peripheral Inflammatory Stratotypes in ALS.\nAbstract: Transactive Response Deoxyribonucleic Acid-Binding Protein-43 (TDP-43) acetylation may couple motor-neuron degeneration to systemic immune orchestration in Amyotrophic Lateral Sclerosis (ALS). Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures.\n\nID: 42156213\nTitle: Dysregulation of arginase and arginine pathways in neurodegenerative diseases: Metabolic and cellular dysfunction and therapeutic implications.\nAbstract: Neurodegenerative diseases are increasingly recognized as disorders associated with metabolic dysfunction with arginine metabolism emerging as a significant contributor. Arginase, by regulating the balance between arginine and ornithine, is positioned at the crossroads of multiple arginine metabolic pathways, thereby controlling a variety of cellular processes essential for proper brain homeostasis. Chronic disruption of these pathways may lead to dysfunction of neurons and glia ultimately resulting in the induction of neurodegenerative processes. In this review, based on data from patients and experimental models, we synthesize and critically evaluate evidence demonstrating alterations in arginase isoenzymes and associated metabolic pathways in Alzheimer's Parkinson's and Huntington's diseases, and amyotrophic lateral sclerosis. We discuss mechanisms through which dysregulation of arginase and arginine metabolism may contribute to neurodegeneration, including disturbances in nitrogen metabolism, oxidative and nitrosative stress, mitochondrial dysfunction, and neuroinflammation. Based on this body of evidence, we propose therapeutic strategies targeting arginase-related pathways, with the aim of preserving cellular metabolic homeostasis to ameliorate disease progression. Finally, we outline directions for future research, emphasizing that a proper understanding of the physiological roles of arginase isoenzymes and their disease-, stage-, and cell-specific dysregulation will be essential for the development of effective metabolically targeted therapies against neurodegenerative diseases.\n\nID: 42141160\nTitle: APOE \u03b54 influences the widespread TDP-43 pathological subtype in sporadic amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder, most sporadic cases exhibiting TAR DNA-binding protein 43 (TDP-43) pathology. The anatomical distribution of TDP-43 pathology varies among patients; however, factors contributing to this heterogeneity remain unclear. Apolipoprotein E (APOE) \u03b54 is known to influence the spread of pathological protein in several neurodegenerative diseases, raising the possibility that it also modulates the pathological distribution of TDP-43 inclusions in ALS. We investigated this hypothesis in a cohort of 145 autopsy-confirmed sporadic ALS cases. ALS-associated TDP-43 pathology was classified into two subtypes: type 1 - largely restricted to motor regions - and type 2 - characterized by widespread cortical involvement. APOE genotypes and rare variants in known ALS-associated genes were determined by exome sequencing. Amyloid-\u03b2 and tau pathologies were assessed neuropathologically using established staging systems. Structural equation modeling (SEM) was applied to disentangle direct and indirect relationships among APOE \u03b54, temporal clinical parameters, Alzheimer's disease-related pathologies, and ALS TDP-43 subtype. Furthermore, we also performed an unbiased evaluation using random forest model. APOE \u03b54 carriers showed a significantly higher proportion of type 2 pathology than non-carriers. Bayesian SEM demonstrated that APOE \u03b54 was directly associated with the type 2, widespread TDP-43 subtype, independent of amyloid-\u03b2 and tau pathology, while also reproducing the canonical cascade linking APOE \u03b54 to amyloid-\u03b2 and tau. Rare variants in ALS-associated genes showed no clear effect on TDP-43 subtype. These findings indicate that APOE \u03b54 modifies the anatomical distribution of TDP-43 pathology in sporadic ALS through mechanisms independent of classical Alzheimer's disease pathology. Incorporation of APOE genotype into ALS stratification may be informative for biologically grounded subtype-specific therapeutic approaches.\n\nID: 42134762\nTitle: Carboplatin alleviates astrocytic TDP-43 neurotoxicity by inhibiting NF-\u03baB activation.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare and progressive motor neuron disease; however, its exact pathogenic mechanisms remain unclear. Currently, no effective treatments are available for this disease. Therefore, in this study, we investigated the anti-inflammatory effects of the anti-cancer agent, carboplatin, on neuronal cells and its potential therapeutic effects against ALS. Carboplatin inhibited NF-\u03baB phosphorylation in the transactive response DNA-binding protein (TDP)-43-transfected astrocytes, reducing pro-inflammatory cytokine levels, without affecting the TDP-43 protein levels. In neuron-astrocyte co-culture models, carboplatin effectively alleviated TDP-43-induced toxicity by restoring mitochondrial integrity, specifically rescuing basal respiration, ATP production, and maximal respiratory capacity. In vivo, carboplatin rescued the locomotor deficits in glial-specific TDP-43-expressing Drosophila, without altering TDP-43 protein levels and subcellular localization. These findings suggest that TDP-43-induced astrocytic damage compromises mitochondrial functions in adjacent neurons, and that carboplatin-mediated restoration of TDP-43-mediated astrocyte damage is critical for neuronal survival and functions. Therefore, carboplatin, a chemotherapeutic agent, represents as a potential therapeutic candidate for TDP-43-associated proteinopathies.\n\nID: 42134658\nTitle: The impact of long-term feeding with curcuminoids phospholipids enriched diet on disease progression of fALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a debilitating and fatal neurodegenerative disease characterised by the progressive loss of motor functions affecting both upper and lower motor neurons. Although considered multifactorial with an unclear aetiology, it is believed that the interplay between genetic and environmental factors, with neuroinflammation playing a key role in disease progression, contributes to its development. There is currently no effective treatment for ALS. Curcumin has been recently highlighted for its potential therapeutic role in treating neurodegenerative diseases. Curcumin phospholipids, a highly bioavailable form of curcumin that allow the curcumin to be absorbed into the bloodstream more effectively than standard curcumin extracts, is considered as a natural cytokine-suppressive anti-inflammatory compound (CSAID) that is well-known for its therapeutic properties and is considered safe for humans and rodents at low to moderate concentrations. In this study, we investigated whether a long-term feeding regimen incorporating curcuminoids phospholipids-enriched diet early in disease progression could mitigate motor deficits and affect the lifespan of the SOD1 mouse model of familial ALS (fALS). Our results indicate sex-differences regarding the effect of curcumin supplementation on motor deficits and anxiety-like behaviour. While long-term feeding with curcuminoids phospholipids enriched diet had a complex effect on SOD1 female mice expressed as reduced anxiety like behaviour and motor deficits at the walking beam test, it had no effect on SOD1 male mice. Moreover, curcuminoids supplementation had a limited effect on disease onset and progression in SOD1 mice model for fALS.\n\nID: 42127907\nTitle: S-acylation of TDP43 regulates its condensation in amyotrophic lateral sclerosis.\nAbstract: TDP43 inclusion bodies are widely present in the majority of patients with familial and sporadic amyotrophic lateral sclerosis (ALS). The mechanisms regulating TDP43 solubility remain incompletely understood. Here, we report that TDP43 undergoes S-acylation primarily at the Cys244 residue by the S-acyltransferase zDHHC23. This S-acylation maintains the liquid-like properties of TDP43 by reducing the aberrant interaction with poly(ADP-ribose) polymerase 1 (PARP1) and PARylated proteins, thereby countering the pathological condensation of TDP43. S-acylation-deficient TDP43 inclusions sequester the translational machinery and inhibit cytoplasmic protein translation, ultimately resulting in neurotoxicity. Importantly, TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons, suggesting the widespread involvement of TDP43 S-acylation in ALS pathogenesis. Our findings reveal an undescribed modification of TDP43 and provide deeper insight into the regulation of TDP43 pathological condensation in ALS.\n\nID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants.\n\nID: 42074133\nTitle: Pridopidine Protects ALS Patient-Derived Neural Progenitor Cells via Sigma-1 Receptor Activation.\nAbstract: The sigma-1 receptor (S1R) is an endoplasmic reticulum (ER)-resident protein enriched at the mitochondria-associated ER membranes (MAMs) that supports ER homeostasis, preserves mitochondrial function, and enhances cell survival under stress. Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress. Co-treatment with the selective S1R antagonist, NE-100, attenuated these effects, supporting an S1R-mediated mechanism of action for pridopidine. Together, these results demonstrate that S1R activation by pridopidine mitigates ER-stress-induced mitochondrial dysfunction and cell loss in ALS-NPCs, resulting in enhanced survival of NPCs supporting the therapeutic potential of pridopidine in ALS.\n\nID: 42069601\nTitle: ALS-FTD-linked CCNFS621G drives increased hippocampal astrocyte ramification and mitochondrial dysfunction and impairs motor neuron excitability.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative diseases with overlapping pathology. Mutations in CCNF, encoding the E3 ubiquitin ligase, Cyclin F, can cause ALS, FTD, or both, even within the same family. Most prior studies of CCNFS621G have relied on overexpression systems, potentially confounding outcomes through disruption of endogenous Cyclin F. Here, we generated the first knock-in mouse model of endogenous CcnfS621G using CRISPR/Cas9. Heterozygous and homozygous CcnfS621G mice showed no motor decline or neuronal loss after 18\u00a0months, however immunohistochemistry revealed increased hippocampal astrocyte ramification, with sex-, age, and subfield-dependent effects. These data indicate that endogenous CcnfS621G may prime early astrocyte alterations in the absence of overt neurodegeneration. Similar astrocyte morphological changes were observed in canonically affected regions of sporadic ALS and FTD-ALS patients post mortem, as well as in CCNFS621G iPSC-derived astrocytes following inflammatory stimulation. Proteomics on Ccnf mice identified early dysregulation of pathways related to translation, mitochondrial function, cytoskeletal remodelling, synaptic transmission and neuroinflammation. Correspondingly, CCNFS621G iPSC-derived astrocytes displayed impaired mitochondrial membrane potential and altered network morphology under both basal and inflammatory stimuli. As altered neuronal excitability is a hallmark of ALS, we examined astrocyte-driven changes to neuronal excitability. CCNFS621G iPSC-derived motor neurons cultured alone were hyperexcitable, firing more action potentials than isogenic controls. Remarkably, co-culture with CCNFS621G astrocytes, but not isogenic control astrocytes, abolished repetitive firing, increased the proportion of neurons unable to generate action potentials, and reduced voltage-gated sodium currents in CCNFS621G and isogenic control neurons. Together, these findings identify astrocyte alterations as an early feature of CCNFS621G-mediated disease, in the absence of neuronal loss. Moreover, the combination of astrocytic mitochondrial dysfunction and the ability of CCNFS621G astrocytes to suppress repetitive neuronal firing suggests a critical astrocyte-driven non-cell autonomous mechanism that may contribute to an oligogenic role for CCNF in ALS/FTD pathogenesis.\n\nID: 42059647\nTitle: Integrated multi-omics analysis reveals gut dysbiosis and altered energy metabolism in Chinese ALS patients.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with a complex etiology. Emerging evidence implicates gut microbiota dysbiosis in ALS pathology via the gut-brain axis, yet the specific integrative profile of the gut microbiome, virome, and metabolome, particularly in Chinese patients, remains incompletely characterized. Although global diversity indices showed no significant differences, taxonomic analysis revealed distinct compositional shifts. The ALS microbiome was characterized by a significant depletion of beneficial anti-inflammatory genera, specifically Akkermansia and Faecalibacterium, and an expansion of opportunistic pathogens such as Escherichia and oral-associated taxa (e.g., Streptococcus). We also observed a specific alteration in the gut virome, with viral genera including Puppervirus and Donellivirus enriched in ALS patients. Functionally, the ALS microbiome exhibited a marked upregulation of pathways involved in L-ascorbate (vitamin C) degradation and fatty acid biosynthesis, suggesting a microbial contribution to systemic oxidative stress. Metabolomic analysis corroborated these findings, identifying 271 differentially expressed metabolites. ALS patients showed elevated levels of inflammatory lipids (e.g., LysoPC) and metabolic intermediates of the tricarboxylic acid (TCA) cycle, alongside a downregulation of antioxidants. Integrative analysis highlighted profound dysregulation in porphyrin metabolism, oxidative phosphorylation, and energy homeostasis. Our findings demonstrate that ALS is associated with a specific dysbiotic gut ecosystem characterized by the loss of protective commensals, unique viral signatures, and functional metabolic reprogramming that exacerbates host oxidative stress and energy deficits. These results provide new insights into gut-brain interactions and highlight microbial antioxidant depletion as a potential therapeutic target.IMPORTANCEAmyotrophic lateral sclerosis (ALS) is a devastating disease with no cure. While gut bacteria are known to influence brain health, we still do not understand exactly how they contribute to ALS progression. In this study, we used advanced DNA sequencing and chemical analysis to deeply examine the gut ecosystem of ALS patients. Beyond just cataloging which bacteria are present, we discovered what they are doing: the ALS microbiome actively breaks down vitamin C (a critical antioxidant) and disrupts energy metabolism. We also found a loss of protective bacteria that maintain the gut barrier. These findings are significant because they suggest that the gut microbiome in ALS patients may be actively fueling the disease by depleting the body's antioxidant reserves. This points to a new potential treatment strategy: targeting these specific bacterial functions or replenishing specific metabolites to protect motor neurons.\n\nID: 42045773\nTitle: Caffeic Acid Phenethyl Ester Enhanced the Klotho/SIRT1/Nrf2/HO-1 Axis to Protect Against Methylmercury-Induced ALS-Like Neurodegeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by motor neuron degeneration, oxidative stress, and neuroinflammation. This study evaluated the neuroprotective potential of caffeic acid phenethyl ester (CAPE) against MTME\u2009+\u20095-induced neurotoxicity in an ALS-like pathology model. CAPE (50 and 100\u00a0mg/kg., p.o.) demonstrated significant therapeutic efficacy by improving motor and cognitive deficits, restoring oxidative balance, and mitigating neuroinflammatory and apoptotic pathways. Behavioral assessments, including the open field, grip strength, forced swim, and Morris water maze, highlighted CAPE's ability to restore neuromuscular coordination and cognitive function in a dose-dependent manner. Cellular and Molecular analyses revealed that MTME+5 exposure significantly disrupted Klotho/SIRT-1/Nrf2/HO-1 antioxidant signaling, increased pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and elevated apoptotic markers (Bax, caspase-3) while depleting anti-inflammatory cytokines (IL-10) and neuroprotective proteins. Furthermore, CAPE treatment restored these parameters, reduced oxidative stress, and enhanced antioxidant defenses (SOD, CAT, r-GSH). Furthermore, CAPE normalized neurotransmitter imbalances, including acetylcholine, dopamine, GABA, serotonin, and glutamate, alleviating excitotoxicity. Histopathological and gross morphological analyses confirmed CAPE50 and CAPE100 ability to preserve neuronal and myelin integrity across key brain regions, including the cerebral cortex, hippocampus, striatum, midbrain, and cerebellum. CAPE also reduced methylmercury accumulation in the brain and cerebrospinal fluid, indicating detoxifying effects. Co-administration of vitamin B1 (VTB1(200)) further amplified CAPE's therapeutic efficacy. Complete blood count (CBC) analysis demonstrated MTME+5-induced hematological abnormalities, including reduced RBCs, hemoglobin, WBCs, and platelets, alongside elevated eosinophils and basophils. CAPE treatment normalized these parameters, indicating systemic recovery. These findings establish CAPE as a promising neuroprotective agent for ALS, capable of targeting neurocomplications.\n\nID: 42035928\nTitle: Analysis of mitochondrial DNA heteroplasmy in sporadic ALS suggests technical limitations rather than disease association.\nAbstract: Mitochondrial DNA (mtDNA) has received increasing attention in amyotrophic lateral sclerosis (ALS) following the recent report of recurrent low-heteroplasmy mtDNA variants in patients. Here, we performed mtDNA analysis on an independent cohort of 20 sporadic ALS patients using an in-house next-generation sequencing pipeline designed for diagnostics. Using standard filters, none of the previously reported low-heteroplasmy mtDNA variants were detected. These variants only appeared in the low-quality data and were present at similar rates in a large reference population without ALS, localizing to homopolymeric regions that are prone to sequencing errors. Our findings suggest that these low-level mtDNA variants are a result of the technical limitations of short-read next-generation sequencing rather than being associated with the disease.\n\nID: 42035155\nTitle: Air pollution and mortality in a University of Michigan amyotrophic lateral sclerosis cohort: a survival analysis.\nAbstract: BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a rare, fatal, neurodegenerative disease. With limited treatment options, identifying modifiable risk factors that impact ALS survival is an important goal. Air pollution may be one such risk factor, yet the research on this topic is limited. METHODS: We assessed survival for ALS patients at the University of Michigan Pranger ALS Clinic who were recruited to participate in a prospective cohort study between 2009 and 2022. Participants\u2019 personal characteristics were linked with residential air pollutant levels of fine particulate matter mass (PM2.5), nitrogen dioxide (NO2), and ozone (O3), as well as several particle components, including black carbon (BC), nitrate, sulfate, and sea-salt (as a negative control) over follow-up. To assess the role of air pollution on ALS mortality we used time-dependent Cox proportional hazards models with days from diagnosis as the time axis, adjusted for potential confounders and co-pollutants. RESULTS: Across the 1,276 total years of person-time during follow-up (2.7\u2009\u00b1\u20092.5 years per participant) there were 329 deaths. In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1\u00a0\u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death. The other pollutants were not associated with death in participants with ALS . CONCLUSIONS: This finding suggests a seven month longer median survival for a 2.1\u00a0\u00b5g/m3 decrease in 1-year average PM2.5, which is significant given that ALS lacks a cure and that existing treatments only extend survival by a few months.\n\nID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.\n\nID: 42381488\nTitle: Neural Organoid Models as a Platform for Studying Disease Mechanisms in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder affecting upper and lower motor neurons leading to muscle wasting. However, structural and molecular abnormalities, including cortical thinning and TDP-43 pathology, extend into frontal, parietal, and temporal areas, pointing to defects across broader cortical regions. The advent of human induced pluripotent stem cell (hiPSC) technology has enabled the generation of human-specific brain cell types in\u00a0vitro. Here, we provide an overview of the three-dimensional (3D) hiPSC-derived neural organoid platforms used to model cortical structures and to study cortical ALS-associated phenotypes. We review which pathological hallmarks have been recapitulated in these organoids and discuss disease phenotypes reported to date. Further, we comprehensively cover different neural organoid models and experimental strategies, including patient-derived hiPSC models and exogenous pathology induction, while addressing current technical challenges. Together, these advances position neural organoids as an emerging tool to study cell-type-specific and circuit-level mechanisms related to cortical changes in ALS.\n\nID: 42375068\nTitle: Distal Motor Latency in Amyotrophic Lateral Sclerosis: A Robust and Reliable Prognostic Marker.\nAbstract: An electrophysiological test is routinely done to confirm Amyotrophic Lateral Sclerosis (ALS) and rule out differentials. Distal Motor Latency (DML) is a simple electrophysiological measure that is always done in a primary setting. It can be used as an excellent prognostic marker for ALS so that we can know ALS better and formulate precise management plans. This longitudinal study was conducted in the Neurology Department of Bangladesh Medical University (BMU), Dhaka, Bangladesh from April 2022 to October 2023. In this study a total of 34 subjects, 17 ALS patients with normal DML and 17 ALS patients with prolonged DML, were enrolled. Severity was assessed by the ALS functional rating scale-revised (ALSFRS-R). The study's endpoints were determined as death during this 6-month follow-up or reaching an advanced stage (ALSFRS-R <20). Then, an electrophysiological test was used to measure DML in all four commonly tested nerves. ALSFRS-R was significantly reduced (p<0.025) at 6 months in ALS patients with prolonged DML than normal DML. It was found that having a higher odd (p<0.012, OR=20.718), prolonged DML had a significant impact on the outcome of ALS patients than that of normal DML. In multivariate analysis, lower ALSFRS-R at diagnosis (B= -0.124, p<0.001, HR=0.883) and prolonged DML (B=1.412, p<0.031, HR=4.104) were associated with poor outcomes. ALS patients with prolonged DML also had a poorer prognosis than patients with normal DML (log-rank test, p<0.045). In this study, patients with prolonged DML had a significant functional decline, rapid disease progression and poor prognosis than patients with normal DML. So, prolonged DML can be used as a robust prognostic marker for patients with ALS.\n\nID: 42365390\nTitle: Lysophagy protects against ANXA11 amyloid fibril toxicity and propagation in FTLD.\nAbstract: Accumulation of Annexin A11 (ANXA11) aggregates is a distinct pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.\n\nID: 42363684\nTitle: FMRP-Mediated Proteasome Regulation: A Novel Mechanism in ALS Pathology.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a rare and fatal neurodegenerative disease characterized by the hallmark cytoplasmic accumulation and aggregation of TAR DNA binding protein 43 (TDP-43), which impairs proteasome activity through its interaction with Tankyrase (TNKS). Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31\u2009kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system. We have demonstrated for the first time that FMRP can act as a disease modifier for ALS. ALS patients with high FMRP expression in the brain and spinal cord may exhibit more severe protein aggregation due to proteasome dysfunction.\n\nID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.\n\nID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown. Together, these findings provided important insights into disease mechanisms and potential avenues for improved clinical management.\n\nID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.\n\nID: 42341118\nTitle: Isoform-specific steric zippers drive aberrant assembly and mislocalization of shortened TDP-43.\nAbstract: Prion-like domain (PrLD)-mediated aggregation and concomitant dysfunction of the essential RNA-binding protein transactive response (TAR) DNA-binding protein of 43 kilodaltons (TDP-43) is a common feature of multiple debilitating neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.\n\nID: 42341041\nTitle: IRE1 regulates the proteostasis of TDP-43/TARDBP in ALS/FTD through ribosome-associated quality control.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are progressive neurodegenerative disorders characterized by motor neuron degeneration, leading to muscle weakness, atrophy, and cognitive impairments. A defining pathological hallmark of ALS/FTD is the cytosolic mislocalization and accumulation of TAR DNA-binding protein 43 (TDP-43), highlighting its critical role in ALS pathogenesis. However, the molecular mechanisms underlying TDP-43 proteostasis remain poorly understood. Through a genetic screening approach, we identify inositol-requiring enzyme 1 (IRE1), an endoplasmic reticulum-resident transmembrane protein, as a potent suppressor of TDP-43 protein levels. Furthermore, we show that ribosome-associated quality control (RQC) factors play a crucial role in regulating TDP-43 proteostasis and cellular toxicity. Activation of the RQC pathway prevents excessive accumulation of TDP-43 and associated toxicity. Mechanistically, our findings suggest that IRE1 regulates TDP-43 protein level by promoting the degradation of aberrant TDP-43 translation product through the RQC pathway. IRE1 acts canonically to enhance the transcription of the RQC core component Clbn/NEMF and noncanonically to physically interact with Clbn/NEMF, thereby ameliorating TDP-43-induced proteotoxicity. Moreover, ectopic expression or pharmacological activation of IRE1 alleviates TDP-43 pathology and restores cognitive function in the TDP-43 A315T ALS mouse models. Collectively, our study identifies a role for IRE1 in the translational quality control of TDP-43 and establishes its potential as a therapeutic target for ALS/FTD.\n\nID: 42337904\nTitle: Are patient-derived models of amyotrophic lateral sclerosis a game changer for novel drug discovery?\nAbstract: ALS drug discovery has long depended on model systems that incompletely capture human disease heterogeneity, aging, and TDP-43 proteinopathy. Patient-derived platforms have therefore emerged as increasingly important human-relevant complements to animal and molecular models. This Critical Perspective examines when patient-derived ALS models genuinely change therapeutic decision-making rather than merely add mechanistic insight. The authors then propose a heuristic framework based on disease-relevant phenotype recapitulation, capture of patient-to-patient heterogeneity, and generation of findings that influence therapeutic prioritization or clinical translation. Furthermore, the authors evaluate iPSC-derived motor neurons, directly reprogrammed neurons, glial co-cultures, organoids, neural networks, and organ-chip systems against these conditions, while also addressing aging fidelity, reproducibility, upper motor neuron modeling, and regulatory implementation. Patient-derived models are not yet standalone decision-grade tools for ALS drug development. Their present value lies in functioning as a human-biology filter for target discovery, reverse translation, biomarker development, and patient stratification when used within rigorous, standardized, and clinically linked workflows. The strongest current evidence supports proof-of-principle rather than generalized predictive validity.\n\nID: 42329964\nTitle: Applications of electromyography in Amyotrophic Lateral Sclerosis: A systematic review.\nAbstract: This systematic review examined the use of surface electromyography (sEMG) for the neuromuscular assessment of individuals with Amyotrophic Lateral Sclerosis (ALS), focusing on clinical parameters, the muscle groups evaluated, acquisition protocols, technical properties of the recording systems, integration with other technologies, and signal processing strategies. We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential.\n\nID: 42314654\nTitle: S-acylation of TDP-43: PALMing down aggregation?\nAbstract: S-acylation is well known for regulating protein stability and trafficking. In a recent issue of Molecular Cell, Xu et al.1 reveal a distinct, aggregation-suppressing function of this posttranslational lipid modification: S-acylation of the RNA-binding protein TDP-43 antagonizes poly(ADP-ribose)-driven condensation. Moreover, reduced S-acylation levels are linked to ALS pathogenesis.\n\nID: 42304808\nTitle: Amyotrophic Lateral Sclerosis Recovery: A New Model System of Care Integrating Neuromuscular Rehabilitation With Clinical Stabilization in ALS.\nAbstract: There is currently no consensus on how to define recovery for individuals with amyotrophic lateral sclerosis (ALS). Tofersen treatment for superoxide dismutase-1-related (SOD1) ALS marks a pivot in clinical management: for the first time, clinicians can target disease stabilization and functional recovery in some individuals. This advancement shifts the focus of ALS care toward optimizing functional recovery alongside symptomatic management. However, there are no evidence-based guidelines for prescribing neuromuscular rehabilitation (NMR) to improve functional recovery. Building on our preliminary single-center data of integrated NMR with tofersen, we propose a new ALS Recovery Model System of Care, utilizing a hub-and-spoke infrastructure to combine NMR with novel therapies. This model aims to define ALS recovery, characterize recovery profiles, standardize NMR protocols, and establish a rehabilitation framework adaptable to future disease-stabilizing therapies.\n\nID: 42262924\nTitle: Human J-domain proteins promote stress granule disassembly and suppress neurodegeneration-linked protein aggregation.\nAbstract: Stress granules are conserved biomolecular condensates that form under stress and rapidly disassemble during recovery. Stress granules have been linked to pathological protein aggregation and their impaired disassembly reduces cell viability, yet the mechanisms governing their clearance and protein aggregation remain unclear. We find that human HSP70 and a subset of J-domain proteins (JDPs) localize to stress granules and that chemical or genetic inhibition of these chaperones markedly slows granule disassembly. Conversely, overexpressing these JDPs, particularly DNAJB1, accelerates disassembly without altering assembly. In vitro, HSP70 and DNAJB1 partition into G3BP1 condensates and reduce their size in an ATP-dependent manner. In cells expressing amyotrophic lateral sclerosis (ALS)-linked mutant FUS, DNAJB1 depletion further impairs stress granule clearance and promotes pre-amyloid accumulation, while depleting a non-stress granule JDP has no effect. Our findings demonstrate that specific JDP chaperones enhance stress granule disassembly and help limit aberrant protein aggregation.\n\nID: 42261056\nTitle: The Flail Limb Syndrome.\nAbstract: The flail limb syndrome is primarily a lower motor neuron disorder that initially affects proximal arm muscles (flail arm syndrome-FAS) or distal leg muscles (flail leg syndrome-FLS). Both were recognized early on (1886 for FAS and 1918 for FLS) as somewhat distinct from classic amyotrophic lateral sclerosis (ALS). Descriptions in the literature are case series with limited information on electrophysiologic features (central and peripheral), cognitive involvement, and genetic mutations. What follows is a compilation of these features. The flail limb syndromes are rare, representing ~7%-8% of ALS. They have a higher ratio of males to females compared to classic ALS. Both are defined by predominant focal arm or leg weakness for ~2\u2009years before progression to other regions, although there can be early and mild clinical or electrophysiologic evidence for denervation and reinnervation in other regions during the initial period. Ultimately, there is progression to respiratory failure, but at a slower rate compared to classic ALS. Upper motor neuron clinical signs are variable, but transcortical magnetic stimulation paradigms and magnetic resonance imaging tractography support upper motor neuron loss. Tests of the split hand pattern show it is rare compared to ALS. Dementia is also rare. Genetic testing supports a spectrum of ALS-related gene mutations but at a lower frequency than with classic ALS, and no gene mutation is predominant. Diagnosis requires ~2\u2009years of regional stability to predict the better prognosis for the flail limb syndromes.\n\nID: 42257902\nTitle: Early respiratory decline around diagnosis and short-term post-landmark outcomes in amyotrophic lateral sclerosis: a 6-month landmark cohort study.\nAbstract: In amyotrophic lateral sclerosis (ALS), respiratory decisions rely on serial trends rather than a single value. We evaluated whether early respiratory decline around diagnosis provides prognostic information in a real-world landmark framework. This single-center retrospective cohort screened 94 consecutive patients diagnosed between April 2019 and December 2025. A 6-month landmark was used. Early decline was estimated from %FVC values between -\u200930 and +\u2009180 days around diagnosis. The primary model included age and early %FVC decline; robustness analyses included time-varying Cox, piecewise Cox, RMST, included-vs-excluded comparison, death-only analysis, and slope-quality filtering. Of 94 screened patients, 62 met baseline eligibility, 56 had calculable early slope, and 45 entered the landmark cohort; 28 post-landmark composite events occurred. In the Cox model, faster early %FVC decline was associated with higher hazard of death or invasive mechanical ventilation via tracheostomy (HR 1.33 per 1%/month faster decline, 95% CI 1.14-1.55, p\u2009<\u20090.001). PH diagnostics suggested non-proportionality (%FVC p\u2009=\u20090.031; NIV p\u2009=\u20090.034 in the expanded model), so this HR was interpreted as an average follow-up association and complemented by PH-robust analyses. The signal was stronger early than late, remained consistent in a death-only analysis, and favored the slower-decline group by RMST at 24 and 36 months. In this selected measurement-capable landmark cohort, early respiratory decline provided a clinically meaningful short-to-medium term prognostic signal for post-landmark adverse outcomes. External validation is required before broader generalization beyond measurement-capable landmark populations.\n\nID: 42250707\nTitle: Inhibitory effect of silymarin on amyloid formation in ALS-associated hSOD1 P66R mutant.\nAbstract: The aberrant aggregation of human superoxide dismutase 1 (hSOD1) into \u03b2-sheet-rich amyloid fibrils is a crucial process in the pathogenesis of amyotrophic lateral sclerosis (ALS), enhancing motor neuron degeneration and disease progression. The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS.\n\nID: 42240799\nTitle: Synaptic Plasticity Changes in the Somatosensory Cortex During Amyotrophic Lateral Sclerosis Progression and After Swim Training in SOD1-G93A Mice.\nAbstract: Somatosensory cortex hyperexcitability is present in the pre-symptomatic stage of amyotrophic lateral sclerosis (ALS) as evidenced by brain recordings, but its synaptic basis remains unclear. We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS.\n\nID: 42237658\nTitle: Neuroprotective Effects of RNS60 in TDP-43 Pathology-Associated Amyotrophic Lateral Sclerosis.\nAbstract: TDP-43 pathology is broadly observed in the cerebral cortex of patients with amyotrophic lateral sclerosis (ALS). RNS60, an experimental treatment for acute ischemic stroke and ALS, enhanced mitochondrial biogenesis and function in other preclinical models. We investigated whether RNS60 improved mitochondrial stability and upper motor neuron (UMN) health in a TDP-43 mouse model of ALS. prpTDP-43A315T-UeGFP mice, in which UMNs express green fluorescent protein (eGFP), and WT-UeGFP mice were treated with RNS60 or placebo intraperitoneally every other day from post-natal day (P) 30 until P90. Astrogliosis and microgliosis in brain and spinal cord were quantified by immunocytochemistry. Mitochondrial ultrastructure was studied via electron microscopy, and mitochondrial function was assessed using flow cytometry. Neuromuscular junction (NMJ) integrity was assessed in gastrocnemius, tibialis, and diaphragm muscles. RNS60 treatment reduced defective mitochondria in UMNs (prpTDP-43A315T\u2009+\u2009vehicle: 53.2%\u2009\u00b1\u20090.71%; prpTDP-43A315T\u2009+\u2009RNS60: 19.6%\u2009\u00b1\u20091.4%, p\u2009=\u20090.0001) and spinal motor neurons (prpTDP-43A315T\u2009+\u2009vehicle: 70.1%\u2009\u00b1\u20090.4.48%; prpTDP-43A315T\u2009+\u2009RNS60: 33.5%\u2009\u00b1\u20094.43%, p\u2009=\u20090.001). It increased mitochondrial membrane polarization (prpTDP-43A315T-UeGFP\u2009+\u2009vehicle: 7184\u2009\u00b1\u20091689 mean intensity; prpTDP-43A315T-UeGFP+RNS60: 22120\u2009\u00b1\u20094818 mean intensity, p\u2009=\u20090.032), reduced the extent of astrogliosis and microgliosis in motor cortex and spinal cord, protected UMNs compared to placebo, and enhanced the proportion of intact NMJs in leg and diaphragm muscles (prpTDP-43A315T-UeGFP\u2009+\u2009vehicle: 29.6%\u2009\u00b1\u20093.6%; prpTDP-43A315T-UeGFP\u2009+\u2009RNS60: 64.3%\u2009\u00b1\u20094.4%, p\u2009=\u20090.0002). These results suggest that RNS60 treatment promotes motor neuron health in ALS by protecting mitochondrial structure and function, preserving NMJ integrity, and reducing gliosis.\n\nID: 42234776\nTitle: Cryptic splicing in synaptic and membrane excitability genes links TDP-43 loss to neuronal dysfunction.\nAbstract: TAR DNA binding protein 43 (TDP-43) pathology is a defining pathological hallmark of multiple neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.\n\nID: 42224592\nTitle: miR-146a is a pleiotropic regulator of motor neuron degeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons. Here, we have profiled motor neuron microRNAs (miRNAs) during motor neuron degeneration in vivo to gain a better understanding of ALS pathophysiology. We demonstrate that one miRNA, miR-146a, is downregulated in diseased motor neurons despite upregulation in bulk tissue. Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed. Finally, we observed that a proportion of miR-146a knockout animals develop spontaneous paralysis, motor neuron loss and chronic neuroinflammation with advanced age. Together these findings demonstrate that a single miRNA influences multiple aspects of motor neuron disease and highlights the complex role for neuroinflammation in ALS pathogenesis.\n\nID: 42352358\nTitle: Extracellular Pgk1 or Its Derived Short Peptide Interacted with Membrane-Associated Enolase 2 Receptor: A Potential Therapy for ALS Motor Neuron Degeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) remains an intractable motor neuron (MN) disease with a growing patient population and few effective treatments. Here, we review how extracellular phosphoglycerate kinase 1 (ePgk1) improves neurite outgrowth of MNs (NOMN) and axonal growth, both in vitro and in vivo. Our group first elucidated a novel non-canonical function of ePgk1 as a cross-tissue mediator between nerve and muscle tissues. We then discovered that neural membranous Enolase 2 (Eno2) serves as a receptor of ligand ePgk1 and that ePgk1-Eno2 interaction suppresses the Rac1-GTP/p-Pak1-T423/p-P38-T180/pMK2-T334/p-Limk1-S323 axis, reducing p-Cofilin and promoting NOMN and axonal growth, finally suggesting that the 419th aspartic acid residue of Eno2 mediates this interaction. In a crucial preclinical step, we truncated two short 16-amino-acid derivatives from Pgk1, FD-1/-2, each mediating neuroprotection comparable to that of full-length 417-amino-acid Pgk1 in ALS animal models, in terms of improvements of innervated neuromuscular junction, MN cell bodies, motor performance, and endpoint prolongation. In this context, we also discuss the opposite function driven by Eno1-plasminogen interaction and by Eno2-ePgk1 interaction; the latter results in unfavorable for tumorigenesis. Unlike intracellular Pgk1 roles, ePgk1 is an extracellular factor with anti-angiogenic properties, further positioning ePgk1 and its FD-1/-2 as promising protein/peptide drugs for ALS treatment.\n\nID: 42324254\nTitle: Direct evidence of upper motor neuron excitability changes in a patient with ALS.\nAbstract: A key feature of amyotrophic lateral sclerosis (ALS) pathophysiology is motor neuron hyperexcitability. However, the mechanisms of hyperexcitability are not well understood. Prior studies have used transcranial magnetic stimulation (TMS) to demonstrate increased motor cortex excitability and reduced intracortical inhibition in human ALS. Yet, interpretation of these findings is limited because measurement of muscle responses cannot disentangle the specific contribution of upper and lower motor neurons and of cortical interneurons to excitability changes. We had the rare opportunity to record directly the corticospinal output evoked by TMS upstream of the spinal circuitry in a patient with ALS who had undergone epidural electrode implantation for intractable pain. Single-pulse stimulation was performed both with a coil orientation inducing a current that activates corticospinal neurons directly, and with a coil orientation inducing a current that activates corticospinal neurons trans-synaptically. Short-interval intracortical inhibition (SICI) was also studied using paired-pulse stimulation. Data obtained from the patient were compared with those recorded in 10 conscious control subjects. Compared with control subjects, patient showed a reduced amplitude in response to direct corticospinal neuron activation, yet an enhanced amplitude of corticospinal output after trans-synaptic corticospinal neuron activation, together with a SICI reduction. Present findings provide direct evidence of hyperexcitability of monosynaptic glutamatergic inputs to corticospinal neurons that, in association with reduced intracortical inhibition, can trigger neurodegeneration. Taken together with the extensive body of evidence generated by noninvasive TMS studies, the findings from this single-case study may provide valuable insights into the pathophysiological mechanisms of the disease.NEW & NOTEWORTHY The response evoked by direct activation of corticospinal neurons is reduced in human amyotrophic lateral sclerosis (ALS). In contrast, the response evoked by trans-synaptic activation of these cells is enhanced. The activity of inhibitory inputs to corticospinal neurons is reduced. These abnormalities related to abnormal excitatory and inhibitory input processing by corticospinal neurons may trigger neurodegeneration.\n\nID: 42309005\nTitle: Limiting neurodegeneration in ALS: A phosphatase paves the way.\nAbstract: Zheng et al. identify phosphatase PGAM5 as a novel promising target for the treatment of different amyotrophic lateral sclerosis subtypes. PGAM5 dephosphorylates and activates the stress-regulated mitochondrial peptidase OMA1, which elicits a maladaptive mitochondrial integrated stress response in motor neurons.\n\nID: 42230361\nTitle: Serum neurofilaments for motoneuron and dementia diseases: a German multicenter cohort study.\nAbstract: Serum neurofilament light and heavy chains (sNfL and sNfH) have been assessed as neuronal markers for amyotrophic lateral sclerosis (ALS) and dementias. Whereas sNfL has robust literature, systematic studies on sNfH are lacking. Here, we aimed to assess the diagnostic value of sNfH in comparison to sNfL in a broad range of neurodegenerative disorders. We measured with immunoassays sNfH and sNfL in patients recruited in the multicenter German Frontotemporal Lobar Degeneration (FTLD) Consortium (n\u2009=\u2009340) and in a single-center German cohort (n\u2009=\u2009290). We assessed the diagnostic accuracy of serum biomarkers for ALS and dementia subtypes and their relationship with cognitive impairment. sNfH and sNfL were significantly increased in ALS (n\u2009=\u200990) vs. controls (n\u2009=\u2009109) and ALS mimics (n\u2009=\u200956, p\u2009<\u20090.001), with sNfL showing higher discriminative accuracy (AUC\u2009=\u20090.94-0.95) than sNfH (AUC\u2009=\u20090.87-0.88). sNfH/sNfL ratio did not improve the diagnostic performance. Both markers were elevated in patients with dementia (n\u2009=\u2009289) vs. controls (p\u2009<\u20090.001). sNfL was higher in behavioral variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA) and Creutzfeldt-Jakob disease (CJD) than in Alzheimer's disease (AD), whereas sNfH was similar in AD, PPA and bvFTD. sNfL, but not sNfH, was correlated with cognitive impairment at baseline\u00a0and cognitive decline at follow-up\u00a0in AD and bvFTD. sNfH and sNfL are elevated in motoneuron and dementia disorders. sNfH showed good discriminative accuracy for ALS, which was slightly lower than that of sNfL. sNfL, but not sNfH, showed prognostic value for assessing\u00a0cognitive decline\u00a0in dementia.\n\nID: 42217760\nTitle: Fluid-based biomarkers of amyotrophic lateral sclerosis: recent advances and future prospects.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder with no definitive cure. The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS.\n\nID: 42211895\nTitle: Peripheral immune cells and glycation indices as potential diagnostic biomarkers in amyotrophic lateral sclerosis.\nAbstract: The diagnosis of amyotrophic lateral sclerosis (ALS) mainly relies on clinical symptoms and the exclusion of other diseases, with a lack of specific biomarkers, leading to delayed diagnosis and a high rate of misdiagnosis. This study aims to explore the utility of peripheral immune cells and glycosylation indices as potential diagnostic biomarkers for ALS to enhance the accuracy and efficiency of early ALS diagnosis. This retrospective study included 54 ALS patients diagnosed in our hospital from June 2023 to October 2024, along with 54 healthy controls. Blood samples and laboratory data, including levels of peripheral immune cells and glycosylation indices, were collected from both groups. Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05). SHAP analysis visualization demonstrated that increased monocyte and decreased leukocyte, HGI, and HbA1c level were all associated with an increased risk of ALS onset, ranked in descending order of feature importance as monocyte, leukocyte, HGI, and HbA1c. Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS. Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis. Further validation in cohorts including disease controls is required to confirm specificity.\n\nID: 42210413\nTitle: VAPB confers selective neuroprotection by driving autophagic degradation of pathogenic aggregates in ALS.\nAbstract: During the progression of amyotrophic lateral sclerosis (ALS), only specific motor neurons (MNs) preferentially deteriorate, while others are spared until the disease reaches its end stage. Resilient MNs possess several protective factors, yet the precise molecular mechanism(s) underlying selective neuronal vulnerability remains poorly understood. Vesicle-associated membrane protein (VAMP)-binding protein B (VAPB) is an endoplasmic reticulum (ER) protein involved in protein quality control (PQC) mechanisms, including unfolded protein response (UPR) as well as autophagy. A dominantly inherited P56S mutation in the VAPB gene has been linked to ALS8, atypical ALS, and late-onset spinal muscular atrophy (SMA). The P56S VAPB mutation causes ER-associated inclusions, disorganization, and ER stress, contributing to MN degeneration through toxic gain and loss of function. Over-expression of VAPB protein confers neuroprotection in a mouse model of ALS, and increased levels of neuronal VAPB inversely correlate with the absence of pathological aggregates. We hypothesize that VAPB is crucial for motor neuron survival by promoting autophagic degradation of ALS-associated aggregates, while lack of VAPB confers neuronal vulnerability. We analyzed the brain and spinal cord from sporadic (s) and familial (f) ALS patients, comparing patterns of VAPB immunoreactivity using immunohistochemistry, complemented by Western and dot blot analysis. Pathophysiological insights from these studies were further explored using cell culture models, including MNs derived from induced pluripotent stem cells (iPSCs). Consistent with our hypothesis we observed that MNs/neurons resistant to ALS exhibited elevated levels of VAPB and were devoid of pathogenic aggregates. Similarly, ALS-resistant oculomotor neurons showed increased VAPB immunoreactivity compared to normal controls. VAPB was often found to be sequestered within toxic aggregates alongside autophagy-related proteins in the lumbar spinal cord MNs. Notably, a compensatory increase in VAPB immunoreactivity was observed at the C-bouton synapse, suggesting a potential alternative mechanism of neuroprotection. Supporting these findings, in vitro experiments indicated that VAPB overexpression promoted autophagy and assisted in clearing ALS-associated RNA-binding protein aggregates. In summary, VAPB promotes selective neuronal survival by facilitating the autophagic clearance of toxic aggregates. Abnormal VAPB accumulations likely disrupt these neuroprotective processes.\n\nID: 42196191\nTitle: Longitudinal CSF and Serum Biomarker Dynamics in Tofersen-Treated SOD1-ALS: A Real-World Multicentre Cohort Study.\nAbstract: Tofersen is a gene-targeted therapy for superoxide dismutase 1 (SOD1)-associated amyotrophic lateral sclerosis (ALS), but neurofilament light chain (NfL) may not fully capture the biological response to treatment. We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.\n\nID: 42175187\nTitle: Identification of Reliable Biomarkers for ALS Through Machine Learning Approach.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron degeneration and limited diagnostic biomarkers. Identifying robust molecular biomarkers for ALS remains a major challenge due to disease heterogeneity and high-dimensional gene expression data. In this study, we developed a machine learning (ML) based pipeline integrating transcriptome data and feature selection to identify potential ALS biomarkers. RNA-Seq data of motor neuron disease patients and healthy controls were obtained from publicly available GEO datasets, followed by preprocessing was performed. We implemented two ensembled ML models such as eXtreme gradient boosting (XGBoost) and random forest (RF) algorithms under a five-fold stratified cross-validation framework to identify the differentially expressed genes. These models were evaluated using the performance metrics. We identified top 10 genes ranked by feature importance from the XGBoost and RF models. Notably, the DCN (Decorin) gene appears consistently in the top 10 features of both models, underscoring its stability and biological relevance. Both ML models exhibited excellent classification performance, with RF achieving 98.8% accuracy and XGBoost achieving 97.6% accuracy, alongside consistently high sensitivity, specificity, precision, and F1-score values. This work highlights the utility of transcriptomic data and ML in identifying key genes as biomarkers for diagnostic and therapeutic potential in ALS.\n\nID: 42173382\nTitle: Tofersen in SOD1-associated amyotrophic lateral sclerosis: From molecular mechanisms to regulatory milestones.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a progressive and ultimately fatal neurodegenerative disorder characterized by degeneration of upper and lower motor neurons. Mutations in the superoxide dismutase 1 (SOD1) gene account for approximately 2% of ALS cases and are associated with toxic protein misfolding and aggregation. Tofersen is an antisense oligonucleotide therapy designed to reduce the synthesis of mutant SOD1 protein through targeted mRNA degradation. While this strategy represents a gene-specific therapeutic approach for a subset of ALS patients, evidence regarding its efficacy, effectiveness and long-term outcomes continues to be evaluated in clinical trials and post-marketing studies. First, to describe the molecular mechanisms underlying SOD1-associated ALS and second, to analyze the therapeutic development, clinical outcomes, and regulatory evolution of tofersen. A narrative review was conducted in PubMed on preclinical and clinical studies published from 2016 through late 2025, complemented by an analysis of public registries and regulatory documentation. Clinical trials were identified through ClinicalTrials.gov and the Clinical Trials Information System (CTIS), and official reports from the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) were reviewed to contextualize their development and regulatory evaluation. Fifty-three publications were identified, of which 20 met predefined inclusion criteria after screening and full-text review. Preclinical studies showed reduced mutant SOD1 expression and prolonged survival in transgenic models. Phase I-II trials demonstrated safety, favorable pharmacokinetics, and dose-dependent reductions in SOD1 in the cerebrospinal fluid and plasma neurofilament light chain (NfL) levels. Although the phase III VALOR trial did not meet the primary ALSFRS-R endpoint (a validated questionnaire-based functional rating scale-revised for determining ALS disease progression) at 28 weeks, significant reductions in the surrogate biomarker NfL indicated target engagement and supported accelerated regulatory approval. Extension data suggested potential clinical benefit with early treatment. Ongoing studies, including ATLAS in presymptomatic carriers, and real-world European data support continued evaluation, alongside accelerated regulatory approvals by FDA and EMA. Tofersen marks a paradigm shift in ALS management, establishing the foundation for precision medicine in neurodegenerative diseases. Its ongoing evaluation in the ATLAS trial will determine whether early intervention can prevent or delay disease onset in presymptomatic SOD1 mutation carriers.\n\nID: 42165374\nTitle: Lighting Up Mislocalized Proteins: Quantum Dot Probes for Multiplexed Cytoplasm-Selective Cell Profiling in Neurodegeneration.\nAbstract: Semiconductor quantum dots (QDs) provide unique stability, brightness, and multiplexed capacity for biomarker detection in complex diseases; however, their distinctive intracellular distribution has rarely been leveraged for spatially resolved diagnostics. Here, we show how QD-based sensors enable selective detection of cytoplasmic proteins and can quantify nucleo-cytoplasm protein mislocalization in patient-derived samples. We validated this approach labeling TAR DNA-binding protein 43 (TDP-43), a key mislocalized protein in amyotrophic lateral sclerosis (ALS). Spatial resolution is achieved in several patient-derived models and mouse brain tissue, underscoring the nanosensor's versatility across biological systems. Multiplexed QD-based immunolabeling, combined with confocal imaging and high-throughput flow cytometry, enables the detection of distinct cytoplasmic biomarker signatures that discriminate ALS patients from healthy controls. These signatures include variations in TDP-43 mislocalization and protein coexpression patterns, which were further modulated by pharmacological treatment. This work establishes QDs as spatially selective, multiplexable nanosensors capable of resolving subtle yet disease-relevant intracellular phenotypes in patient-derived samples. Compared to organic fluorophores, QDs enhance sensitivity, improve signal stability, and enable simultaneous spatially resolved biomarker quantification, broadening their potential for clinical diagnostics and personalized medicine. These findings establish QDs as powerful tools for neurodegeneration research, disease monitoring, and early biomarker discovery, with potential applications in translational neuroscience and precision medicine.\n\nID: 42160515\nTitle: Immunotherapeutic landscape of amyotrophic lateral sclerosis: A bibliometric analysis of research trends, translational priorities, and collaboration networks (2006-2025).\nAbstract: Amyotrophic lateral sclerosis (ALS) remains a major therapeutic challenge, with immune dysregulation increasingly recognized as a critical driver of disease progression. Despite extensive mechanistic research, no immunotherapeutic approach has achieved consistent disease-modifying effects, raising questions about whether this translational gap reflects biological complexity or structural misalignment within the research ecosystem. To characterize the intellectual evolution of ALS immunotherapeutics research, identify immune targets with translational potential, and evaluate collaboration patterns that may influence translational efficiency, we performed a bibliometric analysis of 2,256 publications indexed in Web of Science and Scopus using network-based approaches including co-citation clustering, keyword co-occurrence, and citation burst detection implemented in CiteSpace, VOSviewer, and R-Bibliometrix. Publication output increased 8.4-fold over the study period, delineating three developmental phases. Thematic analyses revealed a shift from early emphasis on microglial biology and SOD1-based models toward recent focus areas including the gut-brain axis, C9orf72-associated immune dysregulation, and advanced immunomodulatory strategies. Collaboration networks remain predominantly regional despite strong contributions from the United States, Europe, and Asia, with limited integration between mechanistic research groups and clinical trial consortia. Among immune-directed therapeutic strategies, regulatory T cell modulation and microglial-targeted approaches exhibit the highest translational readiness. These findings suggest that the lack of effective ALS immunotherapeutics reflects not only biological complexity but also structural and strategic misalignment within the research ecosystem. This bibliometric analysis provides a systems-level framework to guide more integrated translational strategies in ALS immunotherapeutics development.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50). Exposure to nicotine can increase the risks of AD, while conferring protective effects against tremor and EC. Furthermore, exposure to non-nicotine tobacco constituents acts as a risk factor for the incidence of EC.\n --- END ACTUAL ABSTRACT FOR 42304913 ---\n\n- ERROR: You cited ID: 42365206 for the quote: \"People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services.\"\n FACT: Strict Misquote Detected!

People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170 h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected.\n --- END ACTUAL ABSTRACT FOR 42365206 ---\n\n- ERROR: You cited ID: 42360043 for the quote: \"Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients.\"\n FACT: Strict Misquote Detected!

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.\n --- END ACTUAL ABSTRACT FOR 42360043 ---\n\n- ERROR: You cited ID: 42397462 for the quote: \"This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the 'polygenic background' hypothesis.\"\n FACT: Strict Misquote Detected!

While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients.\n --- END ACTUAL ABSTRACT FOR 42397462 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%).\" (Source: 42393482)\n- \"Global pooled incidence was 1.65 per 100 000 person-years (95% CI 1.43 to 1.91), prevalence was 5.05 per 100 000 population (95%\u2009CI 4.26 to 5.99) and mortality was 1.26 per 100 000 person-years (95%\u2009CI 0.94 to 1.69).\" (Source: 42399099)\n- \"Both incidence rate ratio (IRR=0.74) and prevalence rate ratio (PRR=0.69) indicated significantly lower disease burden in females than in males.\" (Source: 42399099)\n- \"The disease burden was significantly higher in high-income countries compared with both upper-middle-income and lower-middle-income countries.\" (Source: 42399099)\n- \"Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially.\" (Source: 42393482)\n- \"These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence.\" (Source: 42247653)\n- \"For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001).\" (Source: 42247653)\n- \"In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1 \u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death.\" (Source: 42035155)\n- \"As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world.\" (Source: 42191932)\n- \"It affects approximately 25 000 individuals in the United States.\" (Source: 42113599)\n- \"Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available.\" (Source: 42367369)\n- \"Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically.\" (Source: 42195033)\n- \"Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants.\" (Source: 42384233)\n- \"Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit.\" (Source: 42224592)\n- \"Amyotrophic lateral sclerosis (ALS) patients are rarely encountered before age 25\u2009years, often associated with genetic variants.\" (Source: 42265995)\n- \"People living with motor neurone disease (MND) increasingly receive complex, life-sustaining interventions at home, including ventilation, tube feeding, and cough assist support.\" (Source: 42403529)\n\n\nINSTRUCTION: Study the actual abstracts provided.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe perspective evaluated is the potential rise in the prevalence and incidence of Amyotrophic Lateral Sclerosis (ALS). The literature indicates that while age-standardized rates have declined in some regions, the absolute global burden of ALS is rising, primarily driven by demographic factors like population aging, population growth, and potentially true increases in incidence in certain populations.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe increasing global burden of ALS is a multifactorial phenomenon. While demographic shifts (aging and population growth) account for a significant portion of the absolute increase in cases, evidence suggests that for MNDs, there is a documented increase in both crude and standardized incidence, distinguishing it from other neurodegenerative conditions where prevalence rises are survival-driven.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe epidemiological landscape of Amyotrophic Lateral Sclerosis (ALS) demonstrates a divergence between age-standardized rates and absolute disease burden. Recent analyses indicate that \"Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%).\" This reflects a broader trend where \"Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially.\" Notably, epidemiological patterns for MNDs appear distinct from other neurodegenerative conditions, as \"These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence.\" This is supported by data stating \"For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001).\" While research into causes is ongoing, environmental factors remain a focus, with studies suggesting that \"In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1 \u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Global prevalence of ALS is estimated at 5.05 per 100,000 population.\n* The disease burden is significantly higher in high-income countries compared to middle-income nations.\n* Male individuals consistently show a significantly higher disease burden than females, with prevalence rate ratios around 0.69.\n* Diagnostic yield for pathogenic variants in ALS is approximately 15.90%, with higher yields (36.95%) in familial cases.\n* Tofersen treatment for SOD1-ALS marks a shift toward functional recovery modeling, creating a new \"Recovery Model System of Care.\"\n* Air pollution (PM2.5) exposure is associated with increased mortality in ALS patients.\n* ALS incidence peaks in the 70-79 age range.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"42035155": "ID: 42035155\nTitle: Air pollution and mortality in a University of Michigan amyotrophic lateral sclerosis cohort: a survival analysis.\nAbstract: BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a rare, fatal, neurodegenerative disease. With limited treatment options, identifying modifiable risk factors that impact ALS survival is an important goal. Air pollution may be one such risk factor, yet the research on this topic is limited. METHODS: We assessed survival for ALS patients at the University of Michigan Pranger ALS Clinic who were recruited to participate in a prospective cohort study between 2009 and 2022. Participants\u2019 personal characteristics were linked with residential air pollutant levels of fine particulate matter mass (PM2.5), nitrogen dioxide (NO2), and ozone (O3), as well as several particle components, including black carbon (BC), nitrate, sulfate, and sea-salt (as a negative control) over follow-up. To assess the role of air pollution on ALS mortality we used time-dependent Cox proportional hazards models with days from diagnosis as the time axis, adjusted for potential confounders and co-pollutants. RESULTS: Across the 1,276 total years of person-time during follow-up (2.7\u2009\u00b1\u20092.5 years per participant) there were 329 deaths. In fully adjusted multi-pollutant models, one interquartile range (IQR) (2.1\u00a0\u00b5g/m3) higher 1-year average PM2.5 was associated with a 66% (HR 1.66 per IQR; 95% CI 1.03\u20132.68) increase in the hazard of death. The other pollutants were not associated with death in participants with ALS . CONCLUSIONS: This finding suggests a seven month longer median survival for a 2.1\u00a0\u00b5g/m3 decrease in 1-year average PM2.5, which is significant given that ALS lacks a cure and that existing treatments only extend survival by a few months.",
"42035928": "ID: 42035928\nTitle: Analysis of mitochondrial DNA heteroplasmy in sporadic ALS suggests technical limitations rather than disease association.\nAbstract: Mitochondrial DNA (mtDNA) has received increasing attention in amyotrophic lateral sclerosis (ALS) following the recent report of recurrent low-heteroplasmy mtDNA variants in patients. Here, we performed mtDNA analysis on an independent cohort of 20 sporadic ALS patients using an in-house next-generation sequencing pipeline designed for diagnostics. Using standard filters, none of the previously reported low-heteroplasmy mtDNA variants were detected. These variants only appeared in the low-quality data and were present at similar rates in a large reference population without ALS, localizing to homopolymeric regions that are prone to sequencing errors. Our findings suggest that these low-level mtDNA variants are a result of the technical limitations of short-read next-generation sequencing rather than being associated with the disease.",
"42045773": "ID: 42045773\nTitle: Caffeic Acid Phenethyl Ester Enhanced the Klotho/SIRT1/Nrf2/HO-1 Axis to Protect Against Methylmercury-Induced ALS-Like Neurodegeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by motor neuron degeneration, oxidative stress, and neuroinflammation. This study evaluated the neuroprotective potential of caffeic acid phenethyl ester (CAPE) against MTME\u2009+\u20095-induced neurotoxicity in an ALS-like pathology model. CAPE (50 and 100\u00a0mg/kg., p.o.) demonstrated significant therapeutic efficacy by improving motor and cognitive deficits, restoring oxidative balance, and mitigating neuroinflammatory and apoptotic pathways. Behavioral assessments, including the open field, grip strength, forced swim, and Morris water maze, highlighted CAPE's ability to restore neuromuscular coordination and cognitive function in a dose-dependent manner. Cellular and Molecular analyses revealed that MTME+5 exposure significantly disrupted Klotho/SIRT-1/Nrf2/HO-1 antioxidant signaling, increased pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2), and elevated apoptotic markers (Bax, caspase-3) while depleting anti-inflammatory cytokines (IL-10) and neuroprotective proteins. Furthermore, CAPE treatment restored these parameters, reduced oxidative stress, and enhanced antioxidant defenses (SOD, CAT, r-GSH). Furthermore, CAPE normalized neurotransmitter imbalances, including acetylcholine, dopamine, GABA, serotonin, and glutamate, alleviating excitotoxicity. Histopathological and gross morphological analyses confirmed CAPE50 and CAPE100 ability to preserve neuronal and myelin integrity across key brain regions, including the cerebral cortex, hippocampus, striatum, midbrain, and cerebellum. CAPE also reduced methylmercury accumulation in the brain and cerebrospinal fluid, indicating detoxifying effects. Co-administration of vitamin B1 (VTB1(200)) further amplified CAPE's therapeutic efficacy. Complete blood count (CBC) analysis demonstrated MTME+5-induced hematological abnormalities, including reduced RBCs, hemoglobin, WBCs, and platelets, alongside elevated eosinophils and basophils. CAPE treatment normalized these parameters, indicating systemic recovery. These findings establish CAPE as a promising neuroprotective agent for ALS, capable of targeting neurocomplications.",
"42059647": "ID: 42059647\nTitle: Integrated multi-omics analysis reveals gut dysbiosis and altered energy metabolism in Chinese ALS patients.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with a complex etiology. Emerging evidence implicates gut microbiota dysbiosis in ALS pathology via the gut-brain axis, yet the specific integrative profile of the gut microbiome, virome, and metabolome, particularly in Chinese patients, remains incompletely characterized. Although global diversity indices showed no significant differences, taxonomic analysis revealed distinct compositional shifts. The ALS microbiome was characterized by a significant depletion of beneficial anti-inflammatory genera, specifically Akkermansia and Faecalibacterium, and an expansion of opportunistic pathogens such as Escherichia and oral-associated taxa (e.g., Streptococcus). We also observed a specific alteration in the gut virome, with viral genera including Puppervirus and Donellivirus enriched in ALS patients. Functionally, the ALS microbiome exhibited a marked upregulation of pathways involved in L-ascorbate (vitamin C) degradation and fatty acid biosynthesis, suggesting a microbial contribution to systemic oxidative stress. Metabolomic analysis corroborated these findings, identifying 271 differentially expressed metabolites. ALS patients showed elevated levels of inflammatory lipids (e.g., LysoPC) and metabolic intermediates of the tricarboxylic acid (TCA) cycle, alongside a downregulation of antioxidants. Integrative analysis highlighted profound dysregulation in porphyrin metabolism, oxidative phosphorylation, and energy homeostasis. Our findings demonstrate that ALS is associated with a specific dysbiotic gut ecosystem characterized by the loss of protective commensals, unique viral signatures, and functional metabolic reprogramming that exacerbates host oxidative stress and energy deficits. These results provide new insights into gut-brain interactions and highlight microbial antioxidant depletion as a potential therapeutic target.IMPORTANCEAmyotrophic lateral sclerosis (ALS) is a devastating disease with no cure. While gut bacteria are known to influence brain health, we still do not understand exactly how they contribute to ALS progression. In this study, we used advanced DNA sequencing and chemical analysis to deeply examine the gut ecosystem of ALS patients. Beyond just cataloging which bacteria are present, we discovered what they are doing: the ALS microbiome actively breaks down vitamin C (a critical antioxidant) and disrupts energy metabolism. We also found a loss of protective bacteria that maintain the gut barrier. These findings are significant because they suggest that the gut microbiome in ALS patients may be actively fueling the disease by depleting the body's antioxidant reserves. This points to a new potential treatment strategy: targeting these specific bacterial functions or replenishing specific metabolites to protect motor neurons.",
"42069601": "ID: 42069601\nTitle: ALS-FTD-linked CCNFS621G drives increased hippocampal astrocyte ramification and mitochondrial dysfunction and impairs motor neuron excitability.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative diseases with overlapping pathology. Mutations in CCNF, encoding the E3 ubiquitin ligase, Cyclin F, can cause ALS, FTD, or both, even within the same family. Most prior studies of CCNFS621G have relied on overexpression systems, potentially confounding outcomes through disruption of endogenous Cyclin F. Here, we generated the first knock-in mouse model of endogenous CcnfS621G using CRISPR/Cas9. Heterozygous and homozygous CcnfS621G mice showed no motor decline or neuronal loss after 18\u00a0months, however immunohistochemistry revealed increased hippocampal astrocyte ramification, with sex-, age, and subfield-dependent effects. These data indicate that endogenous CcnfS621G may prime early astrocyte alterations in the absence of overt neurodegeneration. Similar astrocyte morphological changes were observed in canonically affected regions of sporadic ALS and FTD-ALS patients post mortem, as well as in CCNFS621G iPSC-derived astrocytes following inflammatory stimulation. Proteomics on Ccnf mice identified early dysregulation of pathways related to translation, mitochondrial function, cytoskeletal remodelling, synaptic transmission and neuroinflammation. Correspondingly, CCNFS621G iPSC-derived astrocytes displayed impaired mitochondrial membrane potential and altered network morphology under both basal and inflammatory stimuli. As altered neuronal excitability is a hallmark of ALS, we examined astrocyte-driven changes to neuronal excitability. CCNFS621G iPSC-derived motor neurons cultured alone were hyperexcitable, firing more action potentials than isogenic controls. Remarkably, co-culture with CCNFS621G astrocytes, but not isogenic control astrocytes, abolished repetitive firing, increased the proportion of neurons unable to generate action potentials, and reduced voltage-gated sodium currents in CCNFS621G and isogenic control neurons. Together, these findings identify astrocyte alterations as an early feature of CCNFS621G-mediated disease, in the absence of neuronal loss. Moreover, the combination of astrocytic mitochondrial dysfunction and the ability of CCNFS621G astrocytes to suppress repetitive neuronal firing suggests a critical astrocyte-driven non-cell autonomous mechanism that may contribute to an oligogenic role for CCNF in ALS/FTD pathogenesis.",
"42074133": "ID: 42074133\nTitle: Pridopidine Protects ALS Patient-Derived Neural Progenitor Cells via Sigma-1 Receptor Activation.\nAbstract: The sigma-1 receptor (S1R) is an endoplasmic reticulum (ER)-resident protein enriched at the mitochondria-associated ER membranes (MAMs) that supports ER homeostasis, preserves mitochondrial function, and enhances cell survival under stress. Disruptions of MAM integrity and prolonged ER stress are well-recognized pathological features of amyotrophic lateral sclerosis (ALS), contributing to motor neuron dysfunction and degeneration. In this study, we evaluated the protective effects of pridopidine, a highly selective and potent S1R agonist currently in clinical development for Huntington's disease (HD) and ALS, using neural progenitor cells (NPCs) derived from induced pluripotent stem cells (iPSCs) from a patient with sporadic ALS. Exposure of ALS NPCs to the ER stressor tunicamycin increased the ER stress markers binding immunoglobulin protein (BiP) and C/EBP homologous protein (CHOP), disrupted mitochondrial membrane potential, upregulated expression of the mitochondrial apoptotic marker, BAX, increased caspase-3 activation, and reduced cell viability. Pridopidine significantly attenuated tunicamycin-induced BiP and CHOP expression in a biphasic, dose-dependent manner (with maximal efficacy at 1 \u00b5M), consistent with the typical pharmacology of S1R agonists. Pridopidine restored mitochondrial membrane potential, reduced mitochondrial apoptotic signaling, shown by decreased BAX expression and caspase-3 activation, and improved survival of ALS-NPCs under ER stress. Co-treatment with the selective S1R antagonist, NE-100, attenuated these effects, supporting an S1R-mediated mechanism of action for pridopidine. Together, these results demonstrate that S1R activation by pridopidine mitigates ER-stress-induced mitochondrial dysfunction and cell loss in ALS-NPCs, resulting in enhanced survival of NPCs supporting the therapeutic potential of pridopidine in ALS.",
"42113599": "ID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25\u202f000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants.",
"42127907": "ID: 42127907\nTitle: S-acylation of TDP43 regulates its condensation in amyotrophic lateral sclerosis.\nAbstract: TDP43 inclusion bodies are widely present in the majority of patients with familial and sporadic amyotrophic lateral sclerosis (ALS). The mechanisms regulating TDP43 solubility remain incompletely understood. Here, we report that TDP43 undergoes S-acylation primarily at the Cys244 residue by the S-acyltransferase zDHHC23. This S-acylation maintains the liquid-like properties of TDP43 by reducing the aberrant interaction with poly(ADP-ribose) polymerase 1 (PARP1) and PARylated proteins, thereby countering the pathological condensation of TDP43. S-acylation-deficient TDP43 inclusions sequester the translational machinery and inhibit cytoplasmic protein translation, ultimately resulting in neurotoxicity. Importantly, TDP43 S-acylation is decreased in the familial ALS-associated TDP43 mutants as well as in SOD1-G93A mice and C9orf72-ALS induced pluripotent stem cell (iPSC)-derived neurons, suggesting the widespread involvement of TDP43 S-acylation in ALS pathogenesis. Our findings reveal an undescribed modification of TDP43 and provide deeper insight into the regulation of TDP43 pathological condensation in ALS.",
"42134658": "ID: 42134658\nTitle: The impact of long-term feeding with curcuminoids phospholipids enriched diet on disease progression of fALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a debilitating and fatal neurodegenerative disease characterised by the progressive loss of motor functions affecting both upper and lower motor neurons. Although considered multifactorial with an unclear aetiology, it is believed that the interplay between genetic and environmental factors, with neuroinflammation playing a key role in disease progression, contributes to its development. There is currently no effective treatment for ALS. Curcumin has been recently highlighted for its potential therapeutic role in treating neurodegenerative diseases. Curcumin phospholipids, a highly bioavailable form of curcumin that allow the curcumin to be absorbed into the bloodstream more effectively than standard curcumin extracts, is considered as a natural cytokine-suppressive anti-inflammatory compound (CSAID) that is well-known for its therapeutic properties and is considered safe for humans and rodents at low to moderate concentrations. In this study, we investigated whether a long-term feeding regimen incorporating curcuminoids phospholipids-enriched diet early in disease progression could mitigate motor deficits and affect the lifespan of the SOD1 mouse model of familial ALS (fALS). Our results indicate sex-differences regarding the effect of curcumin supplementation on motor deficits and anxiety-like behaviour. While long-term feeding with curcuminoids phospholipids enriched diet had a complex effect on SOD1 female mice expressed as reduced anxiety like behaviour and motor deficits at the walking beam test, it had no effect on SOD1 male mice. Moreover, curcuminoids supplementation had a limited effect on disease onset and progression in SOD1 mice model for fALS.",
"42134762": "ID: 42134762\nTitle: Carboplatin alleviates astrocytic TDP-43 neurotoxicity by inhibiting NF-\u03baB activation.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare and progressive motor neuron disease; however, its exact pathogenic mechanisms remain unclear. Currently, no effective treatments are available for this disease. Therefore, in this study, we investigated the anti-inflammatory effects of the anti-cancer agent, carboplatin, on neuronal cells and its potential therapeutic effects against ALS. Carboplatin inhibited NF-\u03baB phosphorylation in the transactive response DNA-binding protein (TDP)-43-transfected astrocytes, reducing pro-inflammatory cytokine levels, without affecting the TDP-43 protein levels. In neuron-astrocyte co-culture models, carboplatin effectively alleviated TDP-43-induced toxicity by restoring mitochondrial integrity, specifically rescuing basal respiration, ATP production, and maximal respiratory capacity. In vivo, carboplatin rescued the locomotor deficits in glial-specific TDP-43-expressing Drosophila, without altering TDP-43 protein levels and subcellular localization. These findings suggest that TDP-43-induced astrocytic damage compromises mitochondrial functions in adjacent neurons, and that carboplatin-mediated restoration of TDP-43-mediated astrocyte damage is critical for neuronal survival and functions. Therefore, carboplatin, a chemotherapeutic agent, represents as a potential therapeutic candidate for TDP-43-associated proteinopathies.",
"42141160": "ID: 42141160\nTitle: APOE \u03b54 influences the widespread TDP-43 pathological subtype in sporadic amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder, most sporadic cases exhibiting TAR DNA-binding protein 43 (TDP-43) pathology. The anatomical distribution of TDP-43 pathology varies among patients; however, factors contributing to this heterogeneity remain unclear. Apolipoprotein E (APOE) \u03b54 is known to influence the spread of pathological protein in several neurodegenerative diseases, raising the possibility that it also modulates the pathological distribution of TDP-43 inclusions in ALS. We investigated this hypothesis in a cohort of 145 autopsy-confirmed sporadic ALS cases. ALS-associated TDP-43 pathology was classified into two subtypes: type 1 - largely restricted to motor regions - and type 2 - characterized by widespread cortical involvement. APOE genotypes and rare variants in known ALS-associated genes were determined by exome sequencing. Amyloid-\u03b2 and tau pathologies were assessed neuropathologically using established staging systems. Structural equation modeling (SEM) was applied to disentangle direct and indirect relationships among APOE \u03b54, temporal clinical parameters, Alzheimer's disease-related pathologies, and ALS TDP-43 subtype. Furthermore, we also performed an unbiased evaluation using random forest model. APOE \u03b54 carriers showed a significantly higher proportion of type 2 pathology than non-carriers. Bayesian SEM demonstrated that APOE \u03b54 was directly associated with the type 2, widespread TDP-43 subtype, independent of amyloid-\u03b2 and tau pathology, while also reproducing the canonical cascade linking APOE \u03b54 to amyloid-\u03b2 and tau. Rare variants in ALS-associated genes showed no clear effect on TDP-43 subtype. These findings indicate that APOE \u03b54 modifies the anatomical distribution of TDP-43 pathology in sporadic ALS through mechanisms independent of classical Alzheimer's disease pathology. Incorporation of APOE genotype into ALS stratification may be informative for biologically grounded subtype-specific therapeutic approaches.",

Arginase, by regulating the balance between arginine and ornithine, is positioned at the crossroads of multiple arginine metabolic pathways, thereby controlling a variety of cellular processes essential for proper brain homeostasis. Chronic disruption of these pathways may lead to dysfunction of neurons and glia ultimately resulting in the induction of neurodegenerative processes. In this review, based on data from patients and experimental models, we synthesize and critically evaluate evidence demonstrating alterations in arginase isoenzymes and associated metabolic pathways in Alzheimer's Parkinson's and Huntington's diseases, and amyotrophic lateral sclerosis. We discuss mechanisms through which dysregulation of arginase and arginine metabolism may contribute to neurodegeneration, including disturbances in nitrogen metabolism, oxidative and nitrosative stress, mitochondrial dysfunction, and neuroinflammation. Based on this body of evidence, we propose therapeutic strategies targeting arginase-related pathways, with the aim of preserving cellular metabolic homeostasis to ameliorate disease progression. Finally, we outline directions for future research, emphasizing that a proper understanding of the physiological roles of arginase isoenzymes and their disease-, stage-, and cell-specific dysregulation will be essential for the development of effective metabolically targeted therapies against neurodegenerative diseases.",

Despite extensive mechanistic research, no immunotherapeutic approach has achieved consistent disease-modifying effects, raising questions about whether this translational gap reflects biological complexity or structural misalignment within the research ecosystem. To characterize the intellectual evolution of ALS immunotherapeutics research, identify immune targets with translational potential, and evaluate collaboration patterns that may influence translational efficiency, we performed a bibliometric analysis of 2,256 publications indexed in Web of Science and Scopus using network-based approaches including co-citation clustering, keyword co-occurrence, and citation burst detection implemented in CiteSpace, VOSviewer, and R-Bibliometrix. Publication output increased 8.4-fold over the study period, delineating three developmental phases. Thematic analyses revealed a shift from early emphasis on microglial biology and SOD1-based models toward recent focus areas including the gut-brain axis, C9orf72-associated immune dysregulation, and advanced immunomodulatory strategies. Collaboration networks remain predominantly regional despite strong contributions from the United States, Europe, and Asia, with limited integration between mechanistic research groups and clinical trial consortia. Among immune-directed therapeutic strategies, regulatory T cell modulation and microglial-targeted approaches exhibit the highest translational readiness. These findings suggest that the lack of effective ALS immunotherapeutics reflects not only biological complexity but also structural and strategic misalignment within the research ecosystem. This bibliometric analysis provides a systems-level framework to guide more integrated translational strategies in ALS immunotherapeutics development.",

Here, we show how QD-based sensors enable selective detection of cytoplasmic proteins and can quantify nucleo-cytoplasm protein mislocalization in patient-derived samples. We validated this approach labeling TAR DNA-binding protein 43 (TDP-43), a key mislocalized protein in amyotrophic lateral sclerosis (ALS). Spatial resolution is achieved in several patient-derived models and mouse brain tissue, underscoring the nanosensor's versatility across biological systems. Multiplexed QD-based immunolabeling, combined with confocal imaging and high-throughput flow cytometry, enables the detection of distinct cytoplasmic biomarker signatures that discriminate ALS patients from healthy controls. These signatures include variations in TDP-43 mislocalization and protein coexpression patterns, which were further modulated by pharmacological treatment. This work establishes QDs as spatially selective, multiplexable nanosensors capable of resolving subtle yet disease-relevant intracellular phenotypes in patient-derived samples. Compared to organic fluorophores, QDs enhance sensitivity, improve signal stability, and enable simultaneous spatially resolved biomarker quantification, broadening their potential for clinical diagnostics and personalized medicine. These findings establish QDs as powerful tools for neurodegeneration research, disease monitoring, and early biomarker discovery, with potential applications in translational neuroscience and precision medicine.",

Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures.",

Mutations in the superoxide dismutase 1 (SOD1) gene account for approximately 2% of ALS cases and are associated with toxic protein misfolding and aggregation. Tofersen is an antisense oligonucleotide therapy designed to reduce the synthesis of mutant SOD1 protein through targeted mRNA degradation. While this strategy represents a gene-specific therapeutic approach for a subset of ALS patients, evidence regarding its efficacy, effectiveness and long-term outcomes continues to be evaluated in clinical trials and post-marketing studies. First, to describe the molecular mechanisms underlying SOD1-associated ALS and second, to analyze the therapeutic development, clinical outcomes, and regulatory evolution of tofersen. A narrative review was conducted in PubMed on preclinical and clinical studies published from 2016 through late 2025, complemented by an analysis of public registries and regulatory documentation. Clinical trials were identified through ClinicalTrials.gov and the Clinical Trials Information System (CTIS), and official reports from the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) were reviewed to contextualize their development and regulatory evaluation. Fifty-three publications were identified, of which 20 met predefined inclusion criteria after screening and full-text review. Preclinical studies showed reduced mutant SOD1 expression and prolonged survival in transgenic models. Phase I-II trials demonstrated safety, favorable pharmacokinetics, and dose-dependent reductions in SOD1 in the cerebrospinal fluid and plasma neurofilament light chain (NfL) levels. Although the phase III VALOR trial did not meet the primary ALSFRS-R endpoint (a validated questionnaire-based functional rating scale-revised for determining ALS disease progression) at 28 weeks, significant reductions in the surrogate biomarker NfL indicated target engagement and supported accelerated regulatory approval. Extension data suggested potential clinical benefit with early treatment. Ongoing studies, including ATLAS in presymptomatic carriers, and real-world European data support continued evaluation, alongside accelerated regulatory approvals by FDA and EMA. Tofersen marks a paradigm shift in ALS management, establishing the foundation for precision medicine in neurodegenerative diseases. Its ongoing evaluation in the ATLAS trial will determine whether early intervention can prevent or delay disease onset in presymptomatic SOD1 mutation carriers.",

Identifying robust molecular biomarkers for ALS remains a major challenge due to disease heterogeneity and high-dimensional gene expression data. In this study, we developed a machine learning (ML) based pipeline integrating transcriptome data and feature selection to identify potential ALS biomarkers. RNA-Seq data of motor neuron disease patients and healthy controls were obtained from publicly available GEO datasets, followed by preprocessing was performed. We implemented two ensembled ML models such as eXtreme gradient boosting (XGBoost) and random forest (RF) algorithms under a five-fold stratified cross-validation framework to identify the differentially expressed genes. These models were evaluated using the performance metrics. We identified top 10 genes ranked by feature importance from the XGBoost and RF models. Notably, the DCN (Decorin) gene appears consistently in the top 10 features of both models, underscoring its stability and biological relevance. Both ML models exhibited excellent classification performance, with RF achieving 98.8% accuracy and XGBoost achieving 97.6% accuracy, alongside consistently high sensitivity, specificity, precision, and F1-score values. This work highlights the utility of transcriptomic data and ML in identifying key genes as biomarkers for diagnostic and therapeutic potential in ALS.",

Although often regarded as waste reservoirs, their cellular origins, molecular composition, and pathological significance remain poorly understood. Here, we performed an unbiased proteomic analysis of purified CAs isolated from post-mortem brains of sporadic ALS patients and controls. In-depth mass spectrometry identified 4,470 proteins, of which 658 were quantified, revealing distinct ALS-specific proteomic signatures. Enriched proteins included markers of cytoskeletal remodeling, mitochondrial dysfunction, and proteostasis disruption, as well as known ALS-associated proteins such as TDP-43 and neurofilament proteins. These findings demonstrate that CAs serve as reservoirs of dysfunctional, disease-relevant proteins and capture key pathological processes in ALS. By applying an unbiased proteomic approach to purified CAs, this study provides the first comprehensive map of their protein content in ALS, supporting their potential as biomarker sources and as a source of mechanistic insights into neurodegeneration. Unbiased analyses of CAs in the context of ALS have yet to be undertaken. This study provides the first proteomic profiling of purified CAs, isolated from ALS patient brains using biochemical methods, revealing that CAs harbor disease-relevant proteins implicated in sporadic ALS. By demonstrating that CAs act as reservoirs of dysfunctional proteins related to metabolism, cytoskeletal organization, and proteostasis, our findings highlight their potential as a novel source of ALS-specific mechanistic insight into disease pathology.",

High-resolution HLA data for ALS remain confined to European and East Asian ancestries. We tested whether classical HLA class I and class II variation contributes to ALS susceptibility in a Kuwaiti cohort. We analysed 38 unrelated ALS cases (mean age, 57.4 years; 63.2% male) and 150 population-matched controls (mean age, 57.0 years) from Kuwait. HLA-A, -B, -C, -DRB1, -DQA1, and -DQB1 alleles were typed at two-field resolution using HLA-HD from next-generation sequencing (NGS) data. Allele, haplotype, and amino-acid residue associations were tested in BIGDAWG with locus-specific Bonferroni correction, with additional across-locus sensitivity analysis. Significant class II residues were mapped onto AlphaFold 3 structural models and interpreted alongside published class II crystal structures. No class I allele, haplotype, or residue remained significant after correction. In class II, DQA1*02:01 [odds ratio (OR) = 3.18, 95% confidence interval (CI) 1.67 to 5.95, p c = 0.0007], DRB1*07:01 (OR\u00a0=\u00a03.00, 95% CI: 1.58-5.59, p c = 0.001), and DQB1*02:02 (OR\u00a0=\u00a02.48, 95% CI: 1.28-4.69, p c = 0.03) were enriched in cases. The extended haplotype DQA1*02:01~DQB1*02:02~DRB1*07:01 (DR7-DQ2.2) conferred increased odds of ALS (OR\u00a0=\u00a03.11, 95% CI: 1.53-6.19, p c = 0.002). Amino-acid residue analysis identified convergent risk positions in DQ\u03b11 (positions 47, 52, and 54; OR\u00a0=\u00a03.18, p c = 0.006) and DR\u03b21 (positions 11, 13, 14, 25, and 30; OR\u00a0=\u00a02.84, p c = 0.03) that map to the peptide-binding groove and correspond to the defining motifs of DQA1*02:01 and DRB1*07:01. Using high-resolution NGS-based HLA typing in a Kuwaiti cohort, we identified a class II risk signal for ALS centred on the DR7-DQ2.2 haplotype with convergent residue-level support in the peptide-binding domains. These findings support a contribution of class II-restricted antigen presentation to ALS susceptibility and warrant functional validation and replication in larger, independent Middle Eastern cohorts.",

The most common subtype, amyotrophic lateral sclerosis (ALS), is characterized by both upper and lower motor neuron impairment, which can manifest clinically in the bulbar region or asymmetrically in a limb. Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care. We share our perspective on how the ALS Africa Network is coordinating a shift in the African MND landscape to improve patient care.",

We analyzed associations between plasma markers of oxidative-nitrosative imbalance and ALSFRS-R, disease duration, survival, and routine biochemical parameters. Twenty-nine ALS patients fulfilling the Gold Coast diagnostic criteria were enrolled. Plasma levels of 3-nitrotyrosine (3-NT), 8-oxo-2'-deoxyguanosine (8-oxodG), malondialdehyde (MDA), glutathione (GSH), non-protein thiols (NP-SH), and non-protein disulfides (NP-SS-NP), as well as creatinine, urea, uric acid and BMI, were measured. Associations with ALSFRS-R and disease duration were evaluated using non-parametric correlation analyses and second-order polynomial regression (adjusted R2), while survival was explored using Kaplan-Meier analysis and multivariable Cox regression. Given the modest sample, we considered statistical power and applied Benjamini-Hochberg false discovery rate (FDR) correction within marker families. At the uncorrected significance level, 3-NT showed a positive correlation with ALSFRS-R and a negative correlation with disease duration, and NP-SH correlated negatively with disease duration; however, these associations did not remain significant after FDR correction (FDR-adjusted p \u2265 0.099). Other oxidative-nitrosative markers and biochemical parameters showed no robust relationships with clinical measures. In Cox models, 3-NT was not significantly associated with survival (HR 3.44 per 1 nM, 95% CI 0.25-47.97, p = 0.358), whereas older age predicted higher mortality (HR 1.05 per year, 95% CI 1.00-1.10, p = 0.036). 3-NT and NP-SH exhibited the strongest trends among the investigated markers, but their clinical associations in this small cross-sectional cohort remain exploratory and require confirmation in larger longitudinal studies.",
"42195033": "ID: 42195033\nTitle: From Mutation to Manifestation: Penetrance in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by progressive loss of motor neurons in the brain and spinal cord. While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.",

We performed a multicentre retrospective longitudinal study including 24 patients with SOD1-ALS treated with intrathecal tofersen at four Italian referral centres between 2022 and 2025. Cerebrospinal fluid (CSF) and serum biomarkers were assessed at baseline, month 3, month 6, and last available administration using single-molecule array assays to quantify NfL, glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase L1 (UCHL-1), and total Tau. NfL decreased after treatment initiation in both CSF and serum, providing the clearest pharmacodynamic signal. In contrast, CSF GFAP increased progressively over follow-up, while CSF total Tau and UCHL-1 rose mainly at later timepoints; serum GFAP, total Tau, and UCHL-1 also showed increases during follow-up. ALS Functional Rating Scale-Revised trajectories were broadly stable, whereas disease progression rate was lower at last follow-up than at baseline. Greater reductions in CSF NfL were observed in pathogenic versus uncertain SOD1 variants, and early serum NfL and UCHL-1 changes were associated with longer-term changes in disease progression. These findings suggest that longitudinal multi-analyte profiling may refine biological response stratification beyond NfL alone in tofersen-treated SOD1-ALS.",

APOE genotypes were determined in 289 patients with sporadic ALS, and serum APOE levels were measured in a subset of 222 patients. Cognitive function was assessed using the Edinburgh Cognitive and Behavioural ALS Screen. We examined the association of APOE genotype and serum levels with age at onset, site of onset, disease progression rate (DPR), time to generalization of symptoms (TTG), and cognitive performance. No significant differences were observed in sex, age at onset, site of onset, DPR, or TTG among patients with different APOE genotypes. Similarly, serum APOE levels did not correlate with these clinical variables. However, the APOE-\u03b54 allele was associated with lower ALS-specific cognitive scores, particularly in the domain of verbal fluency. Our study provides preliminary evidence linking the APOE-\u03b54 allele to cognitive impairment, particularly in language fluency, among Chinese patients with ALS. These findings support the hypothesis that APOE genotype contributes to ALS etiology and suggest its role in shaping distinct cognitive phenotypes in the disease.",

Despite extensive research, reliable prognostic biomarkers remain limited, with neurofilament light chain (NfL) being the only marker increasingly implemented in clinical practice. The objective of this study is to assess and compare the prognostic value of NfL, circulating markers of central nervous system (CNS) barrier dysfunction, inflammatory mediators, kynurenine pathway metabolites, and global metabolomic profiles in patients with ALS. Seventy-two patients with ALS from the prospective multicenter METABALS cohort were included. Serum, cerebrospinal fluid (CSF), and urine samples were collected at diagnosis. NfL concentrations, markers of blood-brain and blood-spinal cord barrier permeability (albumin quotient, S100B, neuron-specific enolase [NSE]), 48 inflammatory mediators, kynurenine pathway metabolites, and untargeted metabolomic profiles were measured. Associations with clinical features, disease progression, and survival were investigated using univariate analyses and multivariate models. Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival. Higher serum NfL concentrations at diagnosis predicted shorter survival (ROC AUC\u2009=\u20090.86). In all multivariate and multi-block models, serum NfL was the only biomarker independently associated with survival. Markers of CNS barrier integrity, inflammatory mediators, and metabolomic signatures showed limited prognostic value but provided insights into metabolic remodeling and barrier dysfunction. In this integrated multi-omics study, serum NfL clearly outperformed inflammatory, metabolic, and CNS barrier markers as a prognostic biomarker in ALS, supporting its central role in clinical stratification while complementary biological markers highlighted several relevant pathophysiological mechanisms.",
"42210413": "ID: 42210413\nTitle: VAPB confers selective neuroprotection by driving autophagic degradation of pathogenic aggregates in ALS.\nAbstract: During the progression of amyotrophic lateral sclerosis (ALS), only specific motor neurons (MNs) preferentially deteriorate, while others are spared until the disease reaches its end stage. Resilient MNs possess several protective factors, yet the precise molecular mechanism(s) underlying selective neuronal vulnerability remains poorly understood. Vesicle-associated membrane protein (VAMP)-binding protein B (VAPB) is an endoplasmic reticulum (ER) protein involved in protein quality control (PQC) mechanisms, including unfolded protein response (UPR) as well as autophagy. A dominantly inherited P56S mutation in the VAPB gene has been linked to ALS8, atypical ALS, and late-onset spinal muscular atrophy (SMA). The P56S VAPB mutation causes ER-associated inclusions, disorganization, and ER stress, contributing to MN degeneration through toxic gain and loss of function. Over-expression of VAPB protein confers neuroprotection in a mouse model of ALS, and increased levels of neuronal VAPB inversely correlate with the absence of pathological aggregates. We hypothesize that VAPB is crucial for motor neuron survival by promoting autophagic degradation of ALS-associated aggregates, while lack of VAPB confers neuronal vulnerability. We analyzed the brain and spinal cord from sporadic (s) and familial (f) ALS patients, comparing patterns of VAPB immunoreactivity using immunohistochemistry, complemented by Western and dot blot analysis. Pathophysiological insights from these studies were further explored using cell culture models, including MNs derived from induced pluripotent stem cells (iPSCs). Consistent with our hypothesis we observed that MNs/neurons resistant to ALS exhibited elevated levels of VAPB and were devoid of pathogenic aggregates. Similarly, ALS-resistant oculomotor neurons showed increased VAPB immunoreactivity compared to normal controls. VAPB was often found to be sequestered within toxic aggregates alongside autophagy-related proteins in the lumbar spinal cord MNs. Notably, a compensatory increase in VAPB immunoreactivity was observed at the C-bouton synapse, suggesting a potential alternative mechanism of neuroprotection. Supporting these findings, in vitro experiments indicated that VAPB overexpression promoted autophagy and assisted in clearing ALS-associated RNA-binding protein aggregates. In summary, VAPB promotes selective neuronal survival by facilitating the autophagic clearance of toxic aggregates. Abnormal VAPB accumulations likely disrupt these neuroprotective processes.",

This study aims to explore the utility of peripheral immune cells and glycosylation indices as potential diagnostic biomarkers for ALS to enhance the accuracy and efficiency of early ALS diagnosis. This retrospective study included 54 ALS patients diagnosed in our hospital from June 2023 to October 2024, along with 54 healthy controls. Blood samples and laboratory data, including levels of peripheral immune cells and glycosylation indices, were collected from both groups. Through logistic regression, random forest models, receiver operating characteristic (ROC) curve analysis, and SHAP interpretability analysis, the predictive abilities and clinical significance of each candidate indicator were screened and evaluated. Notable disparities were detected in age, leukocyte count, monocyte levels, glycated haemoglobin A1c (HbA1c), and haemoglobin glycation index (HGI) between the control and ALS groups (all P < 0.05). Logistic regression analysis revealed that age (OR = 1.114) and monocyte (OR = 3.174) were risk factors for ALS, while leukocyte (OR = 0.533) and HbA1c (OR = 0.069) were protective factors. The random forest algorithm, ranked by decreasing importance, showed that leukocyte, HGI, monocyte, and HbA1c level all influenced ALS. Using these indicators to predict ALS resulted in a false-positive rate of 18% and a false-negative rate of 6%. ROC curve analysis indicated that the combined use of leukocyte, monocyte, HbA1c level, and HGI provided the highest diagnostic value for ALS (AUC = 0.774), which was higher than that of any individual indicator (all P < 0.05). SHAP analysis visualization demonstrated that increased monocyte and decreased leukocyte, HGI, and HbA1c level were all associated with an increased risk of ALS onset, ranked in descending order of feature importance as monocyte, leukocyte, HGI, and HbA1c. Peripheral blood white blood cells, monocytes, HbA1c, and HGI can serve as potential diagnostic biomarkers for ALS. Combined detection can improve the diagnostic accuracy of ALS, facilitating early diagnosis and intervention, and ultimately improving patient prognosis. Further validation in cohorts including disease controls is required to confirm specificity.",

Previous studies revealed that the abnormal alterations of some non-motor neurons (non-MN) were a potential pathogenesis of sALS. Therefore, this study aims to search the potential evidences of non-MN in the pathogenesis of ALS via exploring potential relationships between 5-hydroxytryptamine (5-HT) neurons and the development of ALS. We employed fluorescent immunohistochemistry to investigate the altered distribution patterns of 5-HT and tryptophan hydroxylase 2 in the spinal cord and brainstem of Tg(SOD1*G93A)1Gur (TG) and wild-type (WT) mice. Additionally, we used western blot to analyze the expression levels of 5-hydroxytryptamine receptor 1A (5-HTR1A) and 5-HTR2A. Our findings revealed that 5-HT synapses were primarily distributed in the funiculus lateralis, anterior horn, posterior horn, central lateral column, and the area around the central canal of cervical, thoracic, and lumbar segments, and raphe nucleus as well as lateral paragigantocellular nucleus, and gradually reduced following age increase in WT mice. However, 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem gradually increased following the progression of disease and presented a significantly negative correlation between the increased distribution of 5-HT synapses and neurons and the reduction of neural cell number (positively correlated with the increase in neural cell death) at the onset and/or progression stage of TG mice. 5-HTR1A significantly increased, while 5-HTR2A significantly decreased at the onset stage of TG mice. Our study speculated that the distribution changes of 5-HT synapses in the spinal cord and 5-HT neurons in the brainstem play a potential protective role in the pathogenesis of sALS through a compensatory 5-HT increase.",

The absence of specific diagnostic biomarkers leads to diagnostic delays, hindering early intervention and management. This review provides a critical appraisal of fluid-based biomarkers for ALS across multiple sources-cerebrospinal fluid (CSF), blood, urine, saliva, and tears-with emphasis on their diagnostic and prognostic potential, limitations, and readiness for clinical translation. While neurofilaments (NfL, pNfH) are well-established as sensitive indicators of neuroaxonal injury and are increasingly used as prognostic and pharmacodynamic markers in clinical trials, they lack disease specificity. Biomarkers reflecting ALS-specific pathology, such as TDP-43 species and C9orf72 dipeptide repeat proteins (DPRs), show promise but remain in early validation stages with limited multicenter data. Emerging markers from non-invasive sources (urine p75ECD, salivary chromogranin A, tear metabolomics) offer potential for repeated sampling but require rigorous external validation before clinical adoption. To address current gaps, we introduce a standardized evidence grading framework (Tier 1-3) and a comprehensive reporting template for biomarker studies, including explicit performance metrics (AUC, sensitivity, specificity, confidence intervals) and validation status. We also propose minimum reporting standards for study design, pre-analytical variables, and statistical rigor, modeled on REMARK guidelines. A roadmap for biomarker validation and a cross-fluid comparison matrix are provided to guide future research. Despite considerable progress, significant challenges remain, including biological heterogeneity, pre-analytical variability, and insufficient external validation. Future efforts should prioritize multicenter prospective studies, assay harmonization, ethical frameworks for early diagnosis, and integration of emerging technologies such as artificial intelligence and digital twins. Fluid-based biomarkers, while not yet replacing clinical evaluation, are essential tools for accelerating drug development, enabling patient stratification, and moving toward personalized medicine in ALS.",

Our study included 20 patients with sporadic ALS, 10 patients with C9orf72-associated ALS, 10 asymptomatic carriers of the C9orf72 repeat expansion mutation, and 21 nondisease control individuals. Following targeted enzymatic methyl-sequencing (EM-seq) of approximately 4 million CpG sites, we detected numerous differentially methylated genes, including several implicated in ALS disease risk and pathogenesis. By integrating multiple epigenetic features, we delineated a distinct epigenetic signature, which achieved an average area under the curve (AUC) of 0.91 \u00b1 0.10 upon receiver operator characteristic (ROC) analysis, which enabled detection of approximately 70% of patients with ALS with close to 100% specificity. Furthermore, we also identified a set of genes whose methylation status significantly correlated with clinical disease progression and cerebrospinal fluid (CSF) neurofilament levels. Our results reveal the potential of cfDNA-based biomarkers to accurately diagnose ALS and potentially predict disease progression.",

We investigated the spectrum of UNC13A variation and its impact on disease risk and progression in a Chinese ALS cohort. We performed an integrated genetic analysis of 1,533 Chinese ALS patients and 1,405 controls, including rare variant burden testing, genome-wide survival analysis, haplotype mapping, and conditional analyses. An integrated clinical-genetic prognostic score was developed and validated. Rare deleterious UNC13A variants were not associated with ALS risk. We identified two independent haplotype blocks with distinct clinical impacts. Block 1 (tagged by rs75421007) was associated with reduced baseline muscle strength (p\u2009=\u20090.030), while Block 2 (tagged by rs78549703), a brain-specific splicing QTL, was the primary driver of survival heterogeneity. The European variant rs12608932 showed a survival association in single-marker analysis (p\u2009=\u20090.024), but conditional analyses revealed its effect was not independent of Block 2. An integrated prognostic score combining clinical factors and Block 2 haplotype stratified patients into low-, intermediate-, and high-risk groups (median survival: 52.6, 37.1, and 32.0\u2009months; p\u2009<\u20090.001), with decision curve analysis confirming clinical utility. This study delineates UNC13A genetic architecture in Chinese ALS, identifying two independent haplotype blocks that differentially influence disease severity and survival. The Block 2 haplotype, which includes a brain sQTL, is a major determinant of survival heterogeneity and may inform patient stratification in future studies.",

Here, we have profiled motor neuron microRNAs (miRNAs) during motor neuron degeneration in vivo to gain a better understanding of ALS pathophysiology. We demonstrate that one miRNA, miR-146a, is downregulated in diseased motor neurons despite upregulation in bulk tissue. Genetic deletion of miR-146a significantly extended survival in SOD1G93A mice with heterozygous animals demonstrating the largest benefit. A corresponding reduction in spinal cord gliosis but not motor neuron loss was observed. Finally, we observed that a proportion of miR-146a knockout animals develop spontaneous paralysis, motor neuron loss and chronic neuroinflammation with advanced age. Together these findings demonstrate that a single miRNA influences multiple aspects of motor neuron disease and highlights the complex role for neuroinflammation in ALS pathogenesis.",

Whereas sNfL has robust literature, systematic studies on sNfH are lacking. Here, we aimed to assess the diagnostic value of sNfH in comparison to sNfL in a broad range of neurodegenerative disorders. We measured with immunoassays sNfH and sNfL in patients recruited in the multicenter German Frontotemporal Lobar Degeneration (FTLD) Consortium (n\u2009=\u2009340) and in a single-center German cohort (n\u2009=\u2009290). We assessed the diagnostic accuracy of serum biomarkers for ALS and dementia subtypes and their relationship with cognitive impairment. sNfH and sNfL were significantly increased in ALS (n\u2009=\u200990) vs. controls (n\u2009=\u2009109) and ALS mimics (n\u2009=\u200956, p\u2009<\u20090.001), with sNfL showing higher discriminative accuracy (AUC\u2009=\u20090.94-0.95) than sNfH (AUC\u2009=\u20090.87-0.88). sNfH/sNfL ratio did not improve the diagnostic performance. Both markers were elevated in patients with dementia (n\u2009=\u2009289) vs. controls (p\u2009<\u20090.001). sNfL was higher in behavioral variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA) and Creutzfeldt-Jakob disease (CJD) than in Alzheimer's disease (AD), whereas sNfH was similar in AD, PPA and bvFTD. sNfL, but not sNfH, was correlated with cognitive impairment at baseline\u00a0and cognitive decline at follow-up\u00a0in AD and bvFTD. sNfH and sNfL are elevated in motoneuron and dementia disorders. sNfH showed good discriminative accuracy for ALS, which was slightly lower than that of sNfL. sNfL, but not sNfH, showed prognostic value for assessing\u00a0cognitive decline\u00a0in dementia.",

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.",
"42236747": "ID: 42236747\nTitle: Targeting mitophagy for neuroprotection: mechanisms and therapeutic opportunities.\nAbstract: Mitochondria are essential for neuronal energy production, cellular homeostasis, and overall neuronal function. Due to their high metabolic demands and limited regenerative capacity, neurons are particularly vulnerable to mitochondrial dysfunction, which leads to ATP depletion, excessive reactive oxygen species (ROS) production, and calcium imbalance-ultimately causing oxidative stress, metabolic disruption, and neuronal death. Mitophagy is a selective process that removes damaged mitochondria through the autophagy-lysosome pathway. As a key mechanism of mitochondrial quality control, mitophagy preserves energy production, limits oxidative damage, and maintains mitochondrial network integrity. This process is regulated by pathways such as PINK1-Parkin and receptor-mediated mechanisms involving BNIP3 and FUNDC1, all of which help sustain cellular health by preventing mitochondrial dysfunction. Impaired mitophagy is a common feature of several neurodegenerative diseases, including Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS), and Huntington's disease, exacerbating mitochondrial damage and neuronal stress. Emerging therapeutic strategies that target mitophagy-ranging from pharmacological agents and gene therapies to dietary interventions-show promise in restoring mitochondrial quality and protecting neurons from degeneration. Nevertheless, challenges remain in translating these findings into effective clinical treatments. Mitophagy represents a critical mechanism for preserving neuronal integrity and offers a compelling target for innovative therapies against neurodegenerative disorders.",

RNS60, an experimental treatment for acute ischemic stroke and ALS, enhanced mitochondrial biogenesis and function in other preclinical models. We investigated whether RNS60 improved mitochondrial stability and upper motor neuron (UMN) health in a TDP-43 mouse model of ALS. prpTDP-43A315T-UeGFP mice, in which UMNs express green fluorescent protein (eGFP), and WT-UeGFP mice were treated with RNS60 or placebo intraperitoneally every other day from post-natal day (P) 30 until P90. Astrogliosis and microgliosis in brain and spinal cord were quantified by immunocytochemistry. Mitochondrial ultrastructure was studied via electron microscopy, and mitochondrial function was assessed using flow cytometry. Neuromuscular junction (NMJ) integrity was assessed in gastrocnemius, tibialis, and diaphragm muscles. RNS60 treatment reduced defective mitochondria in UMNs (prpTDP-43A315T\u2009+\u2009vehicle: 53.2%\u2009\u00b1\u20090.71%; prpTDP-43A315T\u2009+\u2009RNS60: 19.6%\u2009\u00b1\u20091.4%, p\u2009=\u20090.0001) and spinal motor neurons (prpTDP-43A315T\u2009+\u2009vehicle: 70.1%\u2009\u00b1\u20090.4.48%; prpTDP-43A315T\u2009+\u2009RNS60: 33.5%\u2009\u00b1\u20094.43%, p\u2009=\u20090.001).

We examined synaptic plasticity, the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses, dendritic spine morphology, and the putative excitatory/inhibitory (E/I) ratio in the B2 barrel of the somatosensory cortex in female mice of an ALS mouse model. Transgenic mice, B6SJL-Tg (SOD1*G93A)1Gur/J, were used as the ALS model, and wild-type (WT) B6SJL/F1 mice served as controls. ALS mice were allocated to experimental groups based on disease stage (pre-symptomatic, onset, or terminal) and training condition (swim-trained or untrained). Swim training was applied after the first onset of symptoms (clinical score 1). We analyzed and quantified the density of asymmetric (putative excitatory) and symmetric (putative inhibitory) synapses and E/I ratios using serial electron micrographs to understand how these parameters change during disease progression and whether swim training influences this process. Our results showed stage-dependent alterations in asymmetric (putative excitatory) and symmetric (putative inhibitory) synaptic architecture in ALS. The obtained data showed an increase in the excitatory synaptic density in the presymptomatic ALS mice. This finding is consistent with previous reports of early cortical hyperexcitability and may reflect structural alterations associated with an initial increase in excitatory synapses before disease onset. Importantly, we report here an increase in inhibitory synapses at disease onset. TEM-based synaptic density quantification revealed reduced excitatory synapse density in the B2 barrel of the somatosensory cortex of trained ALS mice compared to WT controls, alongside a trend toward a reduced putative excitatory/inhibitory synaptic ratio. However, as no significant differences were detected between trained and untrained ALS mice, the contribution of swim training to these alterations remains unclear. Notably, swim training was not associated with detectable adverse effects on somatosensory cortex ultrastructure, excitatory synapse density, or the putative excitatory/inhibitory ratio, supporting previous observations that swim training is well tolerated under these experimental conditions. To our knowledge, these results provide the first TEM-based ultrastructural characterization of synaptic architecture in swim-trained SOD1-G93A mice, although further studies are needed to establish the underlying mechanisms and therapeutic relevance in ALS.",

Hyperoside, a bioactive flavonoid, exhibits antioxidant and cytoprotective properties, but its therapeutic relevance to C9orf72-associated ALS remains unclear. To determine whether hyperoside attenuates poly-GR-induced mitochondrial and oxidative injury and improves neuronal survival in cellular and animal models of C9orf72-ALS. A combined in vitro and in vivo experimental study using motor neuron-like cells and an AAV-mediated neonatal mouse model of poly-GR toxicity. NSC34 cells expressing EGFP-GR50 were analyzed for mitochondrial morphology, membrane potential, ROS generation, antioxidant signaling, and apoptosis using confocal microscopy, CellROX/MitoTracker assays, Western blot analysis, and viability testing. For in vivo assessment, neonatal mice received intracerebroventricular AAV9-EGFP-GR50 followed by intraperitoneal hyperoside (10\u00a0mg/kg). Survival, cerebral hemisphere length, and cortical NeuN\u207a neuron numbers were quantified. Poly-GR expression induced pronounced mitochondrial fragmentation, reduced membrane potential, elevated ROS, and suppressed Nrf2/HO-1/GPx4 signaling, accompanied by increased Drp1 and reduced Opa1 expression. Hyperoside reversed these abnormalities by restoring mitochondrial integrity, normalizing the Drp1/Opa1 balance, enhancing Nrf2 nuclear accumulation, and increasing the expression of HO-1 and GPx4. Hyperoside also reduced cleaved caspase-3 and corrected the Bax/Bcl-2 ratio, improving cell viability under basal and oxidative stress conditions. In vivo, hyperoside modestly prolonged survival, increased cerebral hemisphere length, and significantly preserved cortical neuronal numbers in AAV9-EGFP-GR50 mice. Hyperoside mitigates poly-GR-induced neurotoxicity by alleviating excessive mitochondrial fission, strengthening Nrf2-dependent antioxidant defenses, and suppressing apoptosis. These findings support hyperoside as a promising multi-target therapeutic candidate for C9orf72-associated ALS.",

Recent studies have shown that gut microbiota and their metabolites play a key role in the progression of these diseases. Tryptophan (Trp) is an essential amino acid, which mainly produces a variety of biologically active compounds in the intestine through the metabolism of indole pathway, Kynurenine pathway (KP) and serotonin pathway, including indole derivatives, Kynurenine (KYN) and serotonin (5-HT). These metabolites affect the central nervous system (CNS) through the Microbiota-gut-brain axis (MGBA) and affect CNS in a variety of mechanisms, including immune regulation, neuroprotection and maintenance of intestinal barrier function. They are involved in key pathological processes such as neuroinflammation, oxidative stress and pathological protein aggregation. This paper systematically reviews the mechanism of the role of Trp metabolites derived from gut microbiota in NDDs, and explores their specific roles in AD, PD, Amyotrophic Lateral Sclerosis (ALS) and Huntington's disease (HD), and summarizes the potential therapeutic value of the current pathway strategy. These strategies include nutritional intervention, targeted microbiome therapy [such as probiotic and fecal microbiota transplantation (FMT)], and metabolite-derived drugs. Future research must clarify its dynamic mechanism in the human body, develop relevant biomarkers, and promote personalized prevention and treatment strategies through clinical transformation, so as to provide a new direction for early intervention and treatment of NDDs.",

However, it is unclear to what degree this is related to an increase in incidence or to improved survival after diagnosis. We performed 2 nationwide, population-based, retrospective cohort studies, including all individuals living in Sweden between 2001 and 2016 and living in France between 2009 and 2022, respectively. Pooled mixed-effects regression models, with country as a random effect, were used to determine temporal trends in prevalence, crude and age-standardized and sex-standardized incidence, and age and life expectancy at diagnosis. Annualized prevalence of PD, MS, and MNDs increased significantly between 2003 and 2022 in the pooled model (PD: prevalence ratio [PR] per year = 1.014, p < 0.001; MS: PR = 1.029, p < 0.001; MND: PR = 1.028, p < 0.001). While the crude incidence of both PD and MS remained nearly stable over time (PD: incidence rate ratio [IRR] per year = 0.998, p < 0.001; MS: IRR = 0.992, p < 0.001), the standardized incidence showed a more marked decrease for PD (IRR = 0.986, p < 0.001) while remaining almost unchanged for MS (IRR = 0.995, p < 0.001). For MNDs, both the crude and standardized incidence increased over time (crude IRR = 1.018, p < 0.001; standardized IRR = 1.008, p < 0.001). Life expectancy at diagnosis of PD increased between 2003 and 2013 (+0.95 months per calendar year, p < 0.001) and then decreased between 2013 and 2022 (-1.20 months, p = 0.002), while it increased significantly over the entire study period for MS (+2.35 months, p < 0.001) and MNDs (+0.34 months, p = 0.01). These findings indicate that the rising MS prevalence is largely survival-driven and the rising MND prevalence reflects a true increase in incidence, whereas PD prevalence grows modestly, largely independent of incidence. Depending on the mechanism that drives prevalence, whether increased incidence reflecting changing risk factor exposures, improved survival due to therapeutic advances, or demographic aging of the population, inferences about underlying causes differ substantially between PD, MS, and MNDs, with direct implications for health care planning and etiologic research.",

The P66R mutation in SOD1 destabilizes local structure and promotes \u03b2-sheet-driven fibrillation, which makes it a suitable model for exploring approaches for reducing pathogenic aggregation. Here, we evaluate silymarin, a polyphenolic compound with known antioxidant and neuroprotective properties, for its potential to inhibit P66R-hSOD1 aggregation. ThT fluorescence and transmission electron microscopy analyses demonstrate a significant decrease in amyloid fibril formation in the presence of silymarin; in addition, FTIR spectroscopy confirms the suppression of \u03b2-sheet formation. Fluorescence quenching and ANS binding assays indicate a moderate-affinity binding between silymarin and the mutant protein, along with a reduction in surface hydrophobicity. Hemolysis assays confirm its protective effect against membrane damage induced by aggregates, while molecular docking and dynamic simulations indicate that silymarin stabilizes aggregation-prone areas with hydrogen bonding and hydrophobic interactions, thereby promoting compact conformations and reducing solvent-exposed surfaces. The findings identified silymarin as an effective anti-amyloidogenic agent that reduces \u03b2-sheet accumulation and fibril formation while also decreasing cytotoxicity, highlighting its potential as a therapeutic candidate for ALS.",

The primary aim of this translational pilot study was to identify a disease-specific, TDP-43-related, gene-microRNA (miRNA) signature in peripheral blood mononuclear cells (PBMCs) of ALS patients with potential diagnostic value. To this end, we first identified differentially expressed disease-specific genes (dsDEGs) using a TDP-43-based rat model of ALS, generated by stereotaxic infusion of full-length (FL) TAR DNA-binding protein 43 (TDP-43) into the motor cortex. Transcriptomic profiling of the motor cortex revealed candidate dsDEGs, which were subsequently validated by RT-qPCR in motor cortex, spinal cord, and PBMCs from the same animals. To assess translational relevance, expression levels of these dsDEGs were analyzed in PBMCs from early- to mid-stage ALS patients and matched healthy controls, while disease specificity was evaluated using Parkinson's disease (PD) samples. In parallel, conserved miRNAs predicted to target the identified dsDEGs were examined in both rat and human PBMCs. Five dsDEGs, Mctp1, Penk, Mt2A, Drd1, and Rasgrp2, were consistently dysregulated across central and peripheral tissues in the TDP-43 rat model. RT-qPCR analysis of human PBMCs confirmed significant and selective dysregulation of these genes in ALS, but not in PD, supporting disease specificity. Moreover, exposure of human neuroblastoma cells and healthy PBMCs to TDP-43 recapitulated the ALS-like expression changes. Computational and experimental analyses identified seven conserved miRNAs targeting these dsDEGs, of which four were significantly downregulated in ALS PBMCs, supporting a coordinated regulatory network. Receiver operating characteristic (ROC) analyses demonstrated strong discriminative performance for both the gene signature (AUC 0.87-1.00) and the associated miRNAs (AUC 0.95-1.00). Together, these findings define a novel PBMC-based gene-miRNA signature that mirrors central ALS pathology and shows high diagnostic accuracy and disease specificity, highlighting its potential as a minimally invasive biomarker for ALS.",

We evaluated whether early respiratory decline around diagnosis provides prognostic information in a real-world landmark framework. This single-center retrospective cohort screened 94 consecutive patients diagnosed between April 2019 and December 2025. A 6-month landmark was used. Early decline was estimated from %FVC values between -\u200930 and +\u2009180 days around diagnosis. The primary model included age and early %FVC decline; robustness analyses included time-varying Cox, piecewise Cox, RMST, included-vs-excluded comparison, death-only analysis, and slope-quality filtering. Of 94 screened patients, 62 met baseline eligibility, 56 had calculable early slope, and 45 entered the landmark cohort; 28 post-landmark composite events occurred. In the Cox model, faster early %FVC decline was associated with higher hazard of death or invasive mechanical ventilation via tracheostomy (HR 1.33 per 1%/month faster decline, 95% CI 1.14-1.55, p\u2009<\u20090.001). PH diagnostics suggested non-proportionality (%FVC p\u2009=\u20090.031; NIV p\u2009=\u20090.034 in the expanded model), so this HR was interpreted as an average follow-up association and complemented by PH-robust analyses. The signal was stronger early than late, remained consistent in a death-only analysis, and favored the slower-decline group by RMST at 24 and 36 months. In this selected measurement-capable landmark cohort, early respiratory decline provided a clinically meaningful short-to-medium term prognostic signal for post-landmark adverse outcomes. External validation is required before broader generalization beyond measurement-capable landmark populations.",

This study investigated whether immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-glycolipid antibodies are associated with clinical manifestations of ALS, particularly decline in respiratory function. This was a retrospective observational cohort study of the patients with ALS. Among patients with definite or probable limb-onset ALS, 11 patients in the glycolipid IgG-positive group were compared with 15 patients in the IgG-negative group, and 5 patients in the glycolipid IgM-positive group were compared with 9 patients in the IgM-negative group, with adjustment for age. Associations between anti-glycolipid antibody status and respiratory function were assessed using Kaplan-Meier survival analysis and Cox proportional hazards models. The time to decline of percent forced vital capacity (%FVC) below 80% and 60% was significantly shorter in the IgG-positive group than in the IgG-negative group (p\u00a0=\u00a00.002 and p\u00a0=\u00a00.025, respectively). Cox proportional hazards analysis demonstrated that IgG antibody positivity was an independent risk factor for earlier decline in %FVC to 80%.

Ferroptosis, an iron-dependent and lipid peroxidation-associated form of regulated cell death, has recently been identified as a key contributor to neuronal vulnerability. Emerging evidence demonstrates that purified natural monomer compounds derived from medicinal plants exert potent neuroprotective effects by targeting ferroptosis and neuroinflammatory pathways. Representative agents such as curcumin, baicalin, resveratrol, and ginsenoside Rg1 activate nuclear factor E2-related factor-2 and glutathione peroxidase 4 signaling to preserve redox balance, while suppressing microglia-mediated inflammation through inhibition of toll-like receptor 4 pathways. This review highlights the interplay between ferroptosis and neuroinflammation in NDDs, summarizes the regulatory effects of bioactive herbal monomer compounds, and discusses recent advances in multi-omics profiling, nano-delivery strategies, and translational research. By modulating the ferroptosis-neuroinflammation axis, these compounds may represent promising therapeutic candidates for NDDs.",
"42261056": "ID: 42261056\nTitle: The Flail Limb Syndrome.\nAbstract: The flail limb syndrome is primarily a lower motor neuron disorder that initially affects proximal arm muscles (flail arm syndrome-FAS) or distal leg muscles (flail leg syndrome-FLS). Both were recognized early on (1886 for FAS and 1918 for FLS) as somewhat distinct from classic amyotrophic lateral sclerosis (ALS). Descriptions in the literature are case series with limited information on electrophysiologic features (central and peripheral), cognitive involvement, and genetic mutations. What follows is a compilation of these features. The flail limb syndromes are rare, representing ~7%-8% of ALS. They have a higher ratio of males to females compared to classic ALS. Both are defined by predominant focal arm or leg weakness for ~2\u2009years before progression to other regions, although there can be early and mild clinical or electrophysiologic evidence for denervation and reinnervation in other regions during the initial period. Ultimately, there is progression to respiratory failure, but at a slower rate compared to classic ALS. Upper motor neuron clinical signs are variable, but transcortical magnetic stimulation paradigms and magnetic resonance imaging tractography support upper motor neuron loss. Tests of the split hand pattern show it is rare compared to ALS. Dementia is also rare. Genetic testing supports a spectrum of ALS-related gene mutations but at a lower frequency than with classic ALS, and no gene mutation is predominant. Diagnosis requires ~2\u2009years of regional stability to predict the better prognosis for the flail limb syndromes.",

Several lines of evidence implicate inadequate proteostasis in significantly influencing neuronal degeneration. The accumulation of misfolded proteins and proteotoxicity are highlighted as significant factors in ALS pathophysiology. Key pathological hallmarks include ubiquitin-positive inclusions, disrupted RNA metabolism, cytoskeletal perturbations, and compromised axonal transport systems. HDAC6 dysregulation disrupts axonal transport, impairing mitochondrial function and increasing oxidative stress, leading to rapid motor neuron damage and cell death. The enzyme's aberrant deacetylation of \u03b1-tubulin destabilizes microtubules and impairs intracellular trafficking. Despite HDAC6's participation in these unfavorable processes, it also exerts neuroprotective properties. It deacetylates tubulin, promoting efficient axonal transport and autophagic clearance. HDAC6 helps form aggresomes and stress granules, which are essential for cellular defence against proteotoxic stress. Through its zinc finger ubiquitin-binding domain, HDAC6 interacts with polyubiquitinated proteins, facilitating their autophagic degradation. HDAC6 inhibition can boost autophagic flux and reduce protein aggregation, while its activation may amplify the protective effects. This dichotomous behaviour of HDAC6 may pose an obstacle to the design of targeted therapy. Illuminating the complex mechanisms through which HDAC6 influences neurodegeneration and neuroprotection is important before constructing effective treatments for ALS. The review provides a clear understanding of the complex role of HDAC6 in ALS pathogenesis and highlights potential strategies to improve the prognosis of people affected by this neurological illness.",

Current pharmacological treatments primarily provide symptomatic relief and have a limited impact on disease progression. This article presents a narrative review of emerging gene therapy approaches aimed at modulating \u03b1-syn expression, aggregation, and clearance as potential disease-modifying strategies for PD. Gene-based interventions include viral vector-mediated gene delivery, antisense oligonucleotides, RNA interference, and gene-editing technologies. Preclinical studies and early-phase clinical trials suggest that these approaches may reduce \u03b1-syn burden, improve motor outcomes, and support dopaminergic neuron preservation. Adeno-associated viral and lentiviral vectors have demonstrated promise for targeted central nervous system delivery, although challenges related to dosage optimization, regional specificity, long-term safety, and immune responses remain. Complementary strategies focusing on enhancing molecular chaperone activity and activating autophagy-lysosomal pathways have also shown potential in facilitating \u03b1-syn clearance. Despite encouraging progress, several limitations hinder clinical translation, including off-target effects, immune activation, and the need to preserve physiological \u03b1-syn functions essential for neuronal homeostasis. Future success will depend on precise molecular targeting, optimized delivery platforms, and rigorous safety evaluation through well-designed clinical trials. This narrative review summarizes current advances, key limitations, and future directions in \u03b1-syn-targeted gene therapy, highlighting its potential role in advancing PD treatment beyond symptomatic management toward disease modification.",
"42262924": "ID: 42262924\nTitle: Human J-domain proteins promote stress granule disassembly and suppress neurodegeneration-linked protein aggregation.\nAbstract: Stress granules are conserved biomolecular condensates that form under stress and rapidly disassemble during recovery. Stress granules have been linked to pathological protein aggregation and their impaired disassembly reduces cell viability, yet the mechanisms governing their clearance and protein aggregation remain unclear. We find that human HSP70 and a subset of J-domain proteins (JDPs) localize to stress granules and that chemical or genetic inhibition of these chaperones markedly slows granule disassembly. Conversely, overexpressing these JDPs, particularly DNAJB1, accelerates disassembly without altering assembly. In vitro, HSP70 and DNAJB1 partition into G3BP1 condensates and reduce their size in an ATP-dependent manner. In cells expressing amyotrophic lateral sclerosis (ALS)-linked mutant FUS, DNAJB1 depletion further impairs stress granule clearance and promotes pre-amyloid accumulation, while depleting a non-stress granule JDP has no effect. Our findings demonstrate that specific JDP chaperones enhance stress granule disassembly and help limit aberrant protein aggregation.",
"42264545": "ID: 42264545\nTitle: Nanotechnology-enabled targeting strategies for neurodegenerative disorders: role of functionalized nanoparticles.\nAbstract: Neurodegenerative disorders comprise a diverse group of progressive neurological diseases characterized by the gradual loss of neuronal structure and function. Conditions such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis arise from multifactorial mechanisms involving genetic susceptibility, environmental factors, and age-related cellular decline. Key pathogenic processes include oxidative stress, mitochondrial dysfunction, protein misfolding and aggregation, impaired axonal transport, Golgi fragmentation, and chronic neuroinflammation, all of which disrupt neuronal homeostasis and synaptic communication, ultimately leading to neuronal death. Hormonal imbalances further exacerbate these effects by promoting oxidative damage, inflammation, and metabolic dysfunction. Despite advances in understanding disease mechanisms, effective drug delivery remains challenging due to the restrictive nature of the blood-brain barrier. Recent developments highlight the potential of nanoparticle-based drug delivery systems to overcome these limitations. Functionalized nanoparticles enhance blood-brain barrier penetration, improve targeting specificity, and enable controlled drug release. These systems can deliver neuroprotective agents, antioxidants, peptides, and gene therapies directly to affected brain regions. Thus, integrating disease pathophysiology with nanotechnology-based strategies offers a promising approach for improving therapeutic outcomes and advancing precision treatment in neurodegenerative disorders.",

We investigated resistance mechanisms in Chenopodium album (Ca) and C. vulvaria (Cv) from southern Spain following more than two decades of glyphosate-based management. We aimed to (i) confirm resistance to atrazine, tribenuron-methyl (TM), glyphosate, and 2,4-D; (ii) distinguish between target-site and metabolic resistance; and (iii) characterize the biochemical and molecular basis of cross- and multiple-herbicide resistance. Screening assays revealed high survival (78-100%) of resistant (R) populations to acetolactate synthase (ALS)-, photosystem II (PSII)-, auxinic-, and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS)-inhibiting herbicides. Dose-response assays confirmed resistance, with resistance indices (RI) of 6.7 and 5.1 for atrazine, 19.0 and 17.3 for TM, 7.0 and 13.9 for glyphosate, and 6.0 and 6.9 for 2,4-D in CaR and CvR, respectively. Radiolabelled and analytical metabolism assays demonstrated enhanced herbicide metabolism in R populations: atrazine (94-95% vs. 13-16% in S), TM (68-69% vs. 24-25%), 2,4-D (64-65% vs. 2-4%), and glyphosate (39-43% vs. 8-9%). Malathion partially reversed resistance to atrazine, TM, and 2,4-D, supporting cytochrome P450 (CYP450) involvement. In contrast, glyphosate metabolism was independent of CYP450 or glutathione S-transferases inhibition. Biochemical assays showed no differences in PSII or ALS sensitivity (I\u2085\u2080 RI\u00a0\u2248\u00a01), whereas EPSPS inhibition assays revealed a tenfold increase in I\u2085\u2080 in CvR. Sequencing identified a Pro-106-Ser substitution in EPSPS exclusively in CvR. Enhanced metabolism predominates in the R Chenopodium spp. populations, with coexistence of metabolic and target-site mechanisms in CvR, increasing the risk of further cross-resistance under continued herbicide reliance.",
"42265364": "ID: 42265364\nTitle: The asymmetric list shift effect - flexible adaptation to new context demands?\nAbstract: The list-wide proportion congruency effect describes how the congruency effect varies depending on the frequency of incongruent trials within a block. Specifically, the congruency effect is larger in mostly congruent (MC) blocks compared to mostly incongruent (MI) blocks. Research has shown that adaptation to these blocks does not change symmetrically when transitioning between them: moving from MC to MI leads to a rapid decrease in the congruency effect while transitioning from MI to MC results in little or no increase (Abrahamse et al., 2013). We aimed to investigate this asymmetric list shift (ALS) effect in a within-participants design where all participants experienced both transitions (MC-MI and MI-MC). Throughout Experiments 1-3 using a color-word Stroop task, we identified various forms of practice - including trial-type, stimulus-specific learning, general RT decrease, and a decrease in congruency effects over time (see Schmidt, 2016) - that can either facilitate or obscure the ALS effect, depending on the order in which participants experienced the transitions. In Experiment 4, using a face-name version of the Stroop task, where we minimized practice-related confounding factors by employing more complex stimuli and used a new stimulus set in the second transition, an ALS effect was observed regardless of the order of transition and for frequency-unbiased (i.e., 50% congruent) items. The role of practice effects and implications for the (in)-flexibility of control adaptations will be discussed.",

Although animal studies provide evidence for these pathways' role in clearing neurotoxic proteins and distributing solutes delivered to cerebrospinal fluid (CSF), translation to humans is limited. Quantitative, in vivo measures of inter-individual variability in brain fluid clearance in clinical populations are largely lacking. This study investigated the feasibility of estimating brain fluid clearance indices using intrathecal imaging contrast agents. In a prospective and observational study, iodixanol (Visipaque, GE Healthcare, USA, 270\u2009mg I/mL, 3\u2009mL) was administered intrathecally as a CSF tracer and its clearance from CSF to blood was quantified using population pharmacokinetic modeling. Intracranial tracer enrichment in CSF was assessed by its radiodensity (Hounsfield units) within predefined regions of interest (cisterna magna, Sylvian fissure and vertex) on cranial computed tomography (CT) performed 2-, 4- and 24-hours post-injection. These results were compared with brain fluid clearance indices derived from a separate population pharmacokinetic model using intrathecal gadobutrol (Gadovist, Bayer AG, GE, 1.0\u2009mmol/mL, 0.50\u2009mL), with its enrichment in CSF defined as gadobutrol-induced T1 signal increase from baseline within corresponding subarachnoid spaces on magnetic resonance imaging (MRI). The study included 52 subjects receiving intrathecal iodixanol and 45 individuals receiving intrathecal gadobutrol. Marked inter-individual variability was observed in brain fluid clearance to blood for both contrast agents, as well as their distribution in CSF as assessed by CT and MRI. Brain fluid clearance from iodixanol and gadobutrol were significantly correlated. Notably, clearance indices showed stronger correlations with intracranial distribution in CSF for gadobutrol-derived MRI metrics than for iodixanol-derived CT metrics. These findings demonstrate the feasibility of estimating brain fluid clearance in humans using intrathecal imaging contrast agents as CSF tracers. Brain fluid clearance capacity exhibits pronounced inter-individual variability and correlates with the degree of contrast enrichment in intracranial subarachnoid spaces, particularly when assessed by MRI. The results underscore the importance of individualized assessment of brain fluid clearance, with implications for studies on pathogenetic mechanisms of neurodegeneration and optimization of intrathecal drug delivery.",

SOD1 gene variants are well-known to account for a subset of adult-onset ALS but have only been described in a handful of early onset patients. Variants affecting residue 125 in SOD1 have been described in adult-onset ALS patients with a rapid progression. Here we report two such patients. The clinical, genetic, and electrodiagnostic findings of two unrelated adolescents with juvenile onset rapidly progressive SOD1 -ALS are described. Patient 1 presented at 16 and patient 2 at 15\u2009years-of-age with lower limb onset of weakness, lower motor neuron examination findings, and rapid progression over months to involve all body regions. Both patients underwent extensive laboratory, electrophysiologic, and radiologic testing ruling out any alternate etiologies. For both patients, whole-exome sequencing revealed the pathogenic variant p.Asp125Gly in the SOD1 gene inherited from asymptomatic fathers. These two patients expand the phenotypic spectrum of SOD1 -ALS, demonstrating a rapidly progressive juvenile lower limb onset phenotype associated with the p.Asp125Gly variant inherited with incomplete penetrance. Recognition and further characterization of juvenile SOD1 -ALS are important in light of the advances in targeted therapies.",

All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.",

These modifications may not only increase the time and effort required but could also impact drug efficacy and safety. To evaluate the prevalence and the impact of treatment burden on medication adherence and patient-reported quality of life (QoL) in ALS. This prospective multicenter study enrolled ALS patients across three Italian reference centers, with assessments at baseline, 6, and 12\u2009months. Key measures included the Multimorbidity Treatment Burden Questionnaire (MTBQ), ALSFRS-R, DYALS (dysphagia), Morisky Medication Adherence Scale, SSS-8 (somatic symptoms), INQoL (QoL), SWAMECO (swallowing/medication difficulties), alongside comorbidities and current therapies. Associations between treatment burden, QoL, and adherence were analyzed using multivariable models. A total of 114 consecutive ALS patients were enrolled. Clinically significant treatment burden was observed in 69.3% of patients, with over half reporting moderate-to-high levels according to the MTBQ classification. Elevated burden was independently related to greater somatic symptom severity and formulation modification needs. Moreover, higher burden associated with poorer QoL and diminished adherence after confounder adjustment. Longitudinally, patients experiencing worsening burden over 1 year showed accelerated QoL decline compared to those remaining stable, though adherence trajectories were unaffected. Treatment burden, particularly driven by drug formulation complexities and somatic symptoms, emerges as a pivotal, modifiable determinant of adherence and QoL in ALS. Targeted interventions to alleviate modifiable burden components hold promise for optimizing clinical outcomes and enhancing patient-centred care.",

While radiation therapy (RT) plays a pivotal role in the adjuvant treatment of breast cancer, the inclusion of internal mammary lymph nodes (IMLNs) in the radiation field remains controversial due to potential cardiopulmonary toxicity. However, the extent of incidental radiation to the IMLNs, especially with forward planning intensity-modulated radiation therapy (IMRT), remains under-explored. This study aimed to evaluate the incidental radiation dose received by the IMLNs in patients with leftsided breast cancer treated with forward planning IMRT. A total of 36 left-sided breast cancer patients, aged 35-60 years, who underwent modified radical mastectomy followed by adjuvant RT using IMRT, were retrospectively analyzed. CT-based planning and contouring were performed according to RTOG guidelines, with IMLNs contoured retrospectively using Jetwa et al.'s method. Dosimetric parameters for the planning target volume (PTV) and IMLNs were extracted and analyzed using dose-volume histograms. Statistical comparisons were made using the dependent Student's t-test. The PTV received effective radiation coverage with a mean D95 of 38.47 Gy and a mean Dmean of 40.10 Gy. The IMLNs, although not directly targeted, received significant incidental radiation, with a mean D95 of 8.49 Gy, D50 of 21.59 Gy, and Dmean of 21.40 Gy. The maximum dose to the IMLNs (Dmax) reached 38.14 Gy. Comparative analysis revealed statistically significant differences in both Dmax and Dmean between PTV and IMLNs (p = 0.004 and p < 0.001, respectively). Forward planning IMRT provides substantial incidental radiation exposure to the IMLNs, which may have therapeutic implications in reducing recurrence risk. However, this exposure also necessitates careful consideration of potential long-term toxicities to adjacent organs. Further prospective studies are warranted to evaluate the clinical outcomes associated with incidental IMLN irradiation.",

Currently, data on the distribution of places of death (PODs) among these patients is lacking. We examined the distribution of POD among deceased HVRSS patients over a 10-year period and explored clinical factors potentially associated with specific death locations. Additionally, we assessed the agreement between patients' preferred POD (PPOD), as documented in Advance Care Planning (ACP), and their actual POD. We conducted a retrospective cohort study of patients with at least one HVRSS encounter and who had died by 2019. Death-related information was obtained from an administrative dataset and linked with socio-demographic, clinical, and ACP data from other sources. Logistic regression was used to identify clinical factors associated with specific POD. Agreement analysis between actual POD and PPOD was performed among decedents with valid ACP documentation. Among 118 patients studied, 44% died at home, 53% in hospitals, and 3% elsewhere. ACP documentation was available for 52 patients (44.1%), with 73.1% of those preferring home as their POD. Clinical factors associated with home as POD included diagnosis of motor neuron disease (MND) [odds ratio (OR) =5.6; 95% confidence interval (CI): 1.2-25.0; P=0.02], ventilation status at death (OR =14.9; 95% CI: 3.8-58.3; P<0.001), and feeding type at death (OR =3.8; 95% CI: 1.0-14.0; P=0.044).

This is the first study in Singapore to characterise POD patterns and associated factors among home ventilation patients, as well as to evaluate alignment between preferred and actual POD. These findings may inform policy and end-of-life care practices to better support HVRSS patients, particularly at their chosen POD.",

This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.",
"42274592": "ID: 42274592\nTitle: The Role of Iron in Neuronal Homeostasis: A Double-Edged Sword.\nAbstract: Iron is an essential micronutrient that plays a central role in numerous biological processes. Despite its relatively low abundance in the human body, iron is particularly critical for brain function. Systemic and cerebral iron homeostasis is tightly regulated through coordinated mechanisms involving absorption, transport, storage, and recycling. Within the brain, iron metabolism is further controlled by the blood-brain barrier and specialized neural cell populations, including neurons, astrocytes, oligodendrocytes, and microglia. Iron is indispensable for neurodevelopment, supporting neurogenesis, myelination, and neurotransmitter synthesis. However, both iron deficiency and iron overload have detrimental consequences. Early-life iron deficiency disrupts neural development and leads to long-lasting cognitive, motor, and behavioral impairments, whereas excessive iron accumulation promotes oxidative stress, ferroptosis, and neuroinflammation. These mechanisms have been described to contribute to the pathogenesis of major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, neurodegeneration with brain iron accumulation, and amyotrophic lateral sclerosis. This review first outlines systemic and brain iron metabolism, highlighting how neural cells regulate homeostasis. Next, it examines iron's physiological roles, particularly in neurogenesis and neurodevelopment. Finally, it explores iron's involvement in neurodegenerative diseases, emphasizing neuroinflammation as a primary mechanism of iron toxicity.",

Photoactivated chromophore for keratitis-corneal cross-linking (PACK-CXL) offers a\u00a0promising adjunctive or alternative treatment. Narrative review based on the current literature and clinical experience, covering mechanisms of action, clinical evidence, protocol selection and practical decision-making criteria for PACK-CXL. The PACK-CXL acts via three mechanisms: direct killing of pathogens through reactive oxygen species (ROS), increased resistance to protease digestion through steric hindrance and anti-inflammatory effects. Clinical studies demonstrated that adjuvant PACK-CXL shortens the healing time and as monotherapy achieves approximately 89% success in small bacterial ulcers. Higher total radiation doses (high fluence, \u2265\u202f7.2\u202fJ/cm2) are more effective than the standard protocol (5.4\u202fJ/cm2). For Acanthamoeba keratitis, a\u00a0sequential dual chromophore strategy (riboflavin/UV followed by Rose bengal/green light) shows promising results. The use of PACK-CXL enables rapid, largely pathogen-independent treatment of infectious keratitis. Protocol selection should be guided by ulcer size, depth and pathogen type.

Among 745 patients, 717 underwent 1348 SNB procedures and 184 underwent 241 ILND procedures. Postoperative morbidity increased substantially with procedural extent, with complications occurring after 9% of SNB procedures and after 31% of ILND procedures. Lymphoedema developed in 47% of patients following ILND versus 9% following SNB. Increasing lymph node yield independently predicted overall complications within both SNB and ILND cohorts and was additionally associated with wound infection following SNB. For lymphoedema, ILND carried five- to nine-fold higher odds compared with SNB, while higher BMI independently predicted lymphoedema risk (OR 1.07 per kg/m2, p\u2009=\u20090.002). Complications increase markedly with procedure extent. Increasing lymph node yield was associated with wound infection, while lymphoedema is primarily determined by procedure type. Poor predictive ability of patient characteristics limits pre-operative risk stratification.",

There is a considerable variability in the disease progression of sporadic ALS, but the molecular basis for phenotypic heterogeneity remains largely unknown. ALS patients often manifest systemic metabolic abnormalities such as glucose intolerance and hypermetabolic state. We conducted reverse translational research to explore therapeutic targets in ALS based on the systemic metabolic alterations in patients and identified several metabolites associated with the disease progression, including metabolites involved in the expanded endocannabinoid system (ECS). In particular, the levels of N-acyl taurines (NATs) were correlated with the longitudinal change in the revised ALS functional rating scale and survival. Experiments with ALS cellular models, iPS cells derived from ALS patients and SOD1G93A transgenic mice revealed that PF-04457845, a fatty acid amide hydrolase inhibitor, upregulated the expanded ECS, particularly the levels of NATs and ameliorated motor neuron degeneration through the regulation of microglial environment, synapse plasticity, and neuronal development. These results collectively indicate that dysregulation of NATs is associated with ALS progression and PF-04457845 may represent a potential disease-modifying therapy for ALS.",

Several investigations underline the role of nutrition and dietary habits as a preventive strategy. Recent studies suggest that dietary supplementation with polyphenols may constitute an efficient preventive strategy. Indeed, it is emerging that polyphenols exhibit a neuroprotective effect because of their pronounced antioxidant and anti-inflammatory activity. Notably, several studies underline the role of the gut microbiota in the metabolism of the polyphenols, producing bioactive molecules that are absorbed through the gastrointestinal tract. They may exhibit beneficial effects on the central nervous system. Moreover, dietary polyphenols modulate gut microbiota composition, demonstrating a reciprocal regulation between gut microbiota and polyphenol-induced effects on brain functions. Thus, polyphenols are proposed to have an important role on the gut-microbiota-brain axis regulation. The literature search for this narrative review was conducted across three electronic databases PubMed, Scopus, and Web of Science as well as the NIH ClinicalTrials.gov registry, covering the period from January 2000 to 10 February 2026. The following search terms were used: \"polyphenols\", \"microbiota\", \"gut-brain axis\", \"dementia\", \"cognitive function\", \"polyphenols and cognitive dysfunction\", and \"polyphenols and microbiota\". The study selection process was performed in two sequential stages: (i) screening of titles and abstracts, followed by (ii) full-text assessment for eligibility. Articles were included if they were peer-reviewed studies (in vitro, in vivo, or clinical trials), published in English, and addressed the effects of polyphenols on cognitive outcomes, gut microbiota composition, or the gut-microbiota-brain axis. Exclusion criteria included non-peer-reviewed sources, studies lacking relevant cognitive or microbiota-related endpoints, and publications not available in full.",

We previously showed in transgenic mice and postmortem human tissues that PC and PAD2 are altered in amyotrophic lateral sclerosis (ALS), a neurodegenerative disease characterized by motor neurons loss, paralysis, and death. Herein, we investigated the role of PAD2 in ALS by PAD2 knockout in a SOD1-ALS mouse model. To investigate the role of PAD2-induced citrullination in ALS pathogenesis, we generated PAD2 knockout (PAD2KO) in SOD1 G93A ALS mouse model and investigated the consequent modulation on the neuropathology and clinical symptoms, using molecular biology techniques such as qPCR, Western blotting, confocal microscopy, and electron microscopy. Additionally, we identified C3 as being citrullinated in human ALS using ionFinder. Our results show that PAD2KO blocked the increased PC and reduced myelin basic protein (MBP) aggregates in the ALS model. PAD2KO also improved motor neuron survival and the integrity of myelin, axons, and neuromuscular junctions, and reduced microgliosis in the white matter and C3 protein levels in astrocytes. Clinically, data from monitoring the body weight changes suggests that PAD2KO modulates the course of the disease in the ALS mouse model, accelerating the onset while slowing the progression after the onset, and modestly extending the survival of male mice. These results show that PAD2 is responsible for the increased PC in ALS and PC contributes to neuroinflammation and degeneration of motor neurons and myelinated axons. The modest modulation of the disease phenotype suggests that the role of PC in ALS is complex, involving altered PC in numerous proteins and in multiple cell types. Future studies are needed to investigate how PC modulates individual protein functions in various cell types to understand the contribution of PC to ALS pathogenesis.",
"42283497": "ID: 42283497\nTitle: The Long Haul: Microtubule Motors as the Essential Supply Line for Neuronal Longevity.\nAbstract: The extreme morphology and polarised architecture of neurons require the highly sophisticated microtubule transport system for both construction and lifelong survival. Genomic evidence from an expanding landscape of human mutations supports the essential role of the microtubule transport machinery. During neurodevelopment, mutations disrupt the proliferation and migration of neuronal precursors, as well as the initial establishment of polarity. In the mature nervous system, the reliance on microtubule transport shifts to the long-term maintenance of axon integrity and synaptic proteostasis. Across the motor proteins responsible for long distance transport in neurons, mutations highlight a specific vulnerability of long axons to transport failure in Hereditary Spastic Paraplegia (HSP), Charcot Marie Tooth disease Type 2 (CMT2), Spinal Muscular Atrophy (SMA), Perry Syndrome, and Amyotrophic Lateral Sclerosis (ALS) amongst others. Due to the role of microtubule motors in development and maintenance, there is frequently a phenotypic spectrum within a single gene of the microtubule transport system. For example, mutations in dynein motors are linked both to malformations of cortical development and specific motor neuron loss in SMA-LED (Spinal Muscular Atrophy with Lower Extremity Predominance). By synthesising genetic evidence, this review illustrates how specific molecular failures, ranging from motor-domain kinetics to cargo binding, can inform our understanding of neuronal homeostasis. Ultimately, we argue that microtubule transport is not merely a cellular utility, but a key determinant of neuronal longevity.",

New findings on the pathophysiology of the interleukin (IL)-23/IL-17 axis and the role of enthesitis, as well as the identification of subclinical transition phases between psoriasis and manifest arthritis, are fundamentally changing our understanding of psoriatic disease. The concepts of 'therapeutic windows' and 'interception' suggest that early targeted interventions could have a\u00a0lasting positive effect on the progression of the disease. At the same time, clinical reality requires a\u00a0differentiated therapy strategy that considers comorbidities and is oriented towards the individual patient.

"42285406": "ID: 42285406\nTitle: Recent advances in neurodegenerative diseases therapeutics: The inhibition of monoacylglycerol lipase strategy.\nAbstract: Neurodegenerative diseases share common pathophysiological mechanisms, including chronic neuroinflammation, glutamatergic excitotoxicity, oxidative stress, mitochondrial dysfunction, and disruptions in synaptic and lipid homeostasis. In this context, the endocannabinoid system has emerged as a key modulator of neuroimmune communication and neuronal survival. Within this system, Monoacylglycerol Lipase (MAGL) plays a central role by regulating the levels of the endocannabinoid 2-Arachidonoylglycerol (2-AG) while simultaneously contributing to the generation of arachidonic acid and pro-inflammatory eicosanoids. Pharmacological or genetic inhibition of MAGL increases 2-AG levels and concurrently reduces the biosynthesis of pro-inflammatory lipid mediators, thereby modulating microglial activation, astrocytic responses, and neuronal excitotoxicity. Preclinical studies in models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis consistently demonstrate that MAGL blockade attenuates neuroinflammation, preserves synaptic and neuronal integrity, improves motor and cognitive function, and, in some cases, delays disease progression. Although clinical evidence remains limited, the available data position MAGL as a metabolic convergence point between inflammation and neurodegeneration, suggesting that its modulation may represent a therapeutic strategy with disease-modifying potential.",

Uptake by non-gynecologic surgeons could increase population impact. We conducted a national survey of general and urologic surgeons using Michie et al.'s implementation framework of Capability, Motivation, Opportunity-Behaviour to understand understand current experience with opportunistic salpingectomy, and facilitators and barriers to adoption. An online survey was administered to Canadian general and urologic surgeons and postgraduate trainees from January-June 2024. A multivariable logistic regression model assessed relationship between demographic factors and motivation to adopt opportunistic salpingectomy. 269 surveys were completed by 226 general surgeons and 43 urologists. Although 88% reported motivation to perform opportunistic salpingectomy for cancer prevention, practice duration \u226521\u00a0years and province of practice were associated with decreased motivation. Only 44% were aware of recommendations endorsing the procedure, and 19% had performed it. Commonly reported barriers to adoption were Capability (consenting patients regarding permanent contraception and ovarian function, and intraoperative technique/complications), and Opportunity (reimbursement). A surgical video was the preferred method to learn salpingectomy by 94%, and patient consent handouts and intraoperative training by a gynecologist were facilitators. Most (92%) stated that opportunistic salpingectomy training should be offered to postgraduate trainees. Most general and urologic surgeons in Canada were unaware of and have not performed opportunistic salpingectomy but were motivated to offer it. Providing consent resources and training opportunities with gynecologist support, and addressing cultural and regulatory factors may improve uptake by surgeons and decrease ovarian cancer incidence.",

This exploratory pilot study assessed intratracheal airway pressures during prehospital CPR in out-of-hospital cardiac arrest (OHCA). Adult OHCA patients treated by the prehospital Medical Emergency Team of the Ghent University Hospital (Belgium) were prospectively enrolled. Intratracheal pressure was recorded immediately after intubation, mPAW was calculated for both the first and last minutes of advanced life support (ALS). The results were compared between mechanical compressions using the Stryker LUCAS3\u00ae device and manual chest compressions (with chest compression feedback). Nineteen patients were included (manual n\u00a0=\u00a010; mechanical n\u00a0=\u00a09). Initial median mPAW was low (7.74\u00a0mbar) and showed a slight increase over time. Mechanical compressions generated higher early mPAW than manual compressions (8.96 vs. 6.54\u00a0mbar). mPAW increased over time with manual compressions and decreased with mechanical compressions. Patients who achieved return of spontaneous circulation (ROSC) showed higher mPAW, though this difference was not statistically significant. Prehospital mPAW values were substantially lower than those reported in previous ED-based studies. While airway pressure patterns differed between compression modalities, overall pressures were similar. These findings highlight complex airway mechanics during CPR and support further research into whether higher airway pressures could improve airway patency, oxygenation, and hemodynamics in selected OHCA patients.",
"42288852": "ID: 42288852\nTitle: Cognitive, biomarker, and neuroimaging indices associated with traumatic encephalopathy syndrome across two independent athlete cohorts.\nAbstract: Traumatic encephalopathy syndrome (TES) is a clinical research construct used to identify individuals at risk for chronic traumatic encephalopathy (CTE) following exposure to repetitive head impacts (RHI). Adjudication of TES relies on clinical features such as progressive cognitive impairment and neurobehavioral dysregulation. Blood-based biomarkers and structural neuroimaging abnormalities have been associated with TES but are not part of the criteria. This study evaluated whether TES identification was associated with the combined contribution of cognitive performance, blood biomarkers, and structural neuroimaging measures across two well-characterized cohorts. Participants included 158 professional fighters from the Professional Athletes Brain Health Study and 149 former American football players from The DIAGNOSE CTE Research Project. Three indices were constructed representing complementary domains: a cognitive index reflecting cohort-specific cognitive features, a blood biomarker index including plasma neurofilament light chain, glial fibrillary acidic protein, total tau, tau phosphorylated at amino acid 231, and APOE-\u03b54 carrier status, and an imaging index comprising volumetric MRI measures of subcortical structures, ventricles, and corpus callosum subregions. Grouped weighted quantile sum regression models were estimated within each cohort to evaluate associations between these indices and TES while adjusting for age, race, competition status, and RHI exposure. Multidomain models demonstrated improved model performance compared with single-domain models in both cohorts (PABHS: AUC\u2009=\u20090.91, PPV\u2009=\u20090.80; DIAGNOSE CTE: AUC\u2009=\u20090.84, PPV\u2009=\u20090.85). Biomarker and imaging indices contributed additional information across cohorts, although imaging contributions were more prominent in fighters whereas blood biomarker associations were stronger in football players. TES in RHI-exposed athletes was associated with a convergent clinicobiological profile observed across two independent cohorts with distinct exposure patterns. These findings support multidomain analytic frameworks for evaluating correlated biological signals in RHI-exposed populations and may inform future studies of TES and CTE.",

MicroRNAs (miRNAs) have emerged as promising biomarkers due to their involvement in tu- mor progression and in regulating therapy sensitivity. however, the combined clinical signifi ance of circulating and tumor-associated miRNAs, such as hsa-miR-26b-5p and hsa-miR-186-5p, remains insuffi\u00a0\u00a0 \u00a0tly elucidated. Materi- als and Methods. Expression levels of hsa-miR-26b-5p and hsa-miR-186-5p were analyzed in serum and tumor tis- sue of 124 BC patients. Associations with clinicopathological parameters were assessed. The prognostic signifi ance was evaluated based on disease progression and recurrence within 3 years. The predictive value was determined in patients receiving neoadjuvant chemotherapy (4AC regimen) using response assessment and ROC analysis. Re- sults. young BC patients (\u226445 years) demonstrated signifi antly lower circulating levels of both miRNAs. Serum hsa-miR-186-5p expression was associated with early-stage disease, tumor size, lymph node status, and molecular subtype. Increased circulating hsa-miR-26b-5p levels were linked to disease progression, whereas decreased hsa- miR-186-5p levels were observed in patients with unfavorable outcomes. In tumor tissue, hsa-miR-26b-5p expres- sion correlated with tumor grade, size, and metastatic status, showing elevated levels in poorly differentiated tumors and reduced expression in metastatic disease. In contrast, hsa-miR-186-5p was associated with the molecular sub- type and lymph node involvement, with the highest expression observed in hER2-positive tumors and in patients with recurrence. Elevated levels of hsa-miR-186-5p in both serum and tumor tissue were associated with reduced sensitivity to doxorubicin-based neoadjuvant chemotherapy. ROC analysis confi med its predictive value (AUC = \u00a00.750 for serum and 0.818 for tumor tissue). No signifi ant association between hsa-miR-26b-5p and chemothe- rapy response was observed. hsa-miR-26b-5p and hsa-miR-186-5p demonstrate complementary roles in BC biology. hsa-miR-26b-5p is primarily associated with tumor aggressiveness and cancer progression, whereas hsa-miR-186-5p refl cts its molecular characteristics and response to chemotherapy. Their combined assessment in serum and tumor tissue represents a promising approach for improving prognostic stratifi ation and predicting treatment effi acy in BC patients.",

Patients with PD were classified according to initial motor phenotype (tremor-dominant vs. bradykinetic-rigid) and cognitive status based on Mini-Mental State Examination (MMSE) scores (21-26 indicating cognitive impairment; \u226527 indicating normal cognition). High-resolution three-dimensional T1-weighted SPGR MRI data were analyzed using the VolBrain automated segmentation pipeline to obtain volumetric measurements of the putamen, caudate nucleus, globus pallidus, and thalamus. All volumetric measures were normalized to total intracranial volume (TIV). Associations between regional brain volumes and Unified Parkinson's Disease Rating Scale (UPDRS) sub-scores were assessed.

Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.",

A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.",
"42299014": "ID: 42299014\nTitle: Pathogenic Proteins Driving ALS Pathogenesis: Molecular Mechanisms and Translational Therapeutic Perspectives.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of motor neurons, with protein aggregation as a central pathological hallmark. Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.",

Despite extensive research, riluzole and edaravone remain the only globally approved disease-modifying therapies, offering modest survival benefits. This review summarizes current understanding of ALS pathogenesis, approved pharmacological treatments, and emerging gene-, RNA-, and cell-based therapeutic strategies. Particular emphasis is placed on regulatory considerations and evolving clinical trial designs in ALS drug development. The accelerated approval and subsequent withdrawal of sodium phenylbutyrate-taurursodiol (AMX0035) are discussed as a critical case study highlighting the challenges of regulatory flexibility in rare, fatal diseases. Advances in biomarker development, especially neurofilament light chain, are examined for their growing role in trial design and therapeutic evaluation. Collectively, these insights underscore a shift toward biomarker- informed and precision-based approaches that may improve future ALS therapeutic development.",

Using a SASP reporter combined with a CRISPR-Cas9 screen targeting active regulatory elements, we identify the zinc-finger protein ZNF512B as a key suppressor of the SASP. ZNF512B loss induces DNA damage, activates cGAS-STING signaling, and triggers inflammatory transcriptional reprogramming. In contrast, ZNF512B promotes preferential DNA repair at regulatory genomic regions, limiting SASP induction. Mechanistically, ZNF512B is rapidly recruited to DNA-damage sites via distinct zinc-finger domains and facilitates NuRD complex targeting to damaged chromatin, enabling precise repair. In human neuromuscular organoids, ZNF512B deficiency induces inflammation, lineage imbalance, and cytokine secretion resembling amyotrophic lateral sclerosis (ALS)-associated pathology. In vivo, ZNF512B overexpression reduces DNA damage and inflammation following acute liver injury. Together, these findings support a mechanism of preferential DNA repair that contributes to maintaining genome integrity, suppressing SASP and inflammation.",

Here we characterize the breadth of these associations and identify biological axes that may mediate them. Using UK Biobank data, we developed a multi-omic analysis pipeline integrating physiological, radiomic, metabolomic and genomic information. We trained retinal adversarial autoencoders to represent optical coherence tomography images and color fundus photographs as 256-dimensional embeddings. Retinal adversarial autoencoder-derived embeddings were associated with a range of cardiovascular and neurodegenerative diseases, including ischemic heart disease, cerebrovascular disease, Parkinson's disease and dementia. Examining associations across diverse omics datasets, we provide evidence linking ophthalmic imaging features to neurological and cardiovascular anatomy and function, lipid metabolism and gene sets associated with neurodegenerative pathology. Collectively, our findings show that ophthalmic features reflect complex, multisystem biological processes and reinforce the role of the eye as a composite indicator of systemic health.",

Tofersen treatment for superoxide dismutase-1-related (SOD1) ALS marks a pivot in clinical management: for the first time, clinicians can target disease stabilization and functional recovery in some individuals. This advancement shifts the focus of ALS care toward optimizing functional recovery alongside symptomatic management. However, there are no evidence-based guidelines for prescribing neuromuscular rehabilitation (NMR) to improve functional recovery. Building on our preliminary single-center data of integrated NMR with tofersen, we propose a new ALS Recovery Model System of Care, utilizing a hub-and-spoke infrastructure to combine NMR with novel therapies. This model aims to define ALS recovery, characterize recovery profiles, standardize NMR protocols, and establish a rehabilitation framework adaptable to future disease-stabilizing therapies.",

This uncertainty limits the interpretation of nicotine- and nAChR-targeted therapeutic strategies, especially as electronic nicotine delivery sys-tems become more common. We used Mendelian randomization to genetically separate nicotine-related effects from smoking-related non-nicotine effects on major neurodegenerative diseases and related prodromal conditions. We performed univariable two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analyses. Summary-level exposure data for cigarettes per day (CPD) and the nicotine metabolite ratio (NMR) were analyzed against individual-level, smoking-stratified outcome data derived from 337,334 UK Biobank participants, to evaluate their respective causal effects across six neurodegenerative outcomes: Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), tremor, early cognitive impairment (EC), and other neurodegenerative diseases (OND). MVMR analyses revealed that nicotine exposure was a causal risk factor for AD (ever smokers: OR=0.90, 95% CI 0.83-0.98; current smokers: OR=0.76, 95% CI 0.64-0.91). Nicotine exerted a causal protective effect against tremor (OR=1.24, 95% CI 1.03-1.49) and EC (OR=1.14, 95% CI 1.04-1.24) in current smokers. Non-nicotine tobacco constituents were identified as risk factors among former smokers for EC (OR=1.61, 95% CI 1.04-2.50). Exposure to nicotine can increase the risks of AD, while conferring protective effects against tremor and EC. Furthermore, exposure to non-nicotine tobacco constituents acts as a risk factor for the incidence of EC.",

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.",
"42307135": "ID: 42307135\nTitle: Brain activity in an end-stage ALS patient suggests the presence of an unresponsive wakefulness syndrome.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor neurons. It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40\u2009Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3\u2009Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS.",

"42310292": "ID: 42310292\nTitle: Impact of BECLIN1 haploinsufficiency on goblet cell function and susceptibility to colitis.\nAbstract: BECLIN1 is a central regulator of autophagy and endocytic trafficking essential for epithelial homoeostasis. While complete intestinal epithelial loss of BECLIN1 causes fatal enteritis originating in the small intestine, the consequences of its partial loss in the gut remain unclear. Given that BECLIN1 expression can vary in human disease, we investigated whether reduced BECLIN1 is sufficient to impair gut barrier function. Heterozygous Becn1 deletion (Becn1IEC+/-) in the mouse intestinal epithelium caused subtle but significant defects. These included shortened small intestines and altered epithelial architecture, despite preservation of basal autophagy, implicating trafficking-related functions. Supporting this conclusion, Becn1IEC+/- small intestinal epithelial cells showed modest increases in RAB5+ve vesicles, redistribution of E-CADHERIN and F-actin along lateral membranes and altered apico-basal cell morphology. Given the absence of overt small intestinal epithelial disruption or inflammation, as seen with complete loss of BECLIN1, we next addressed whether BECLIN1 insufficiency manifests a phenotype under stress or in other gut regions. Indeed, in the colon, Becn1IEC+/- mice exhibited reduced colonic crypt length, baseline goblet cell loss and reduced mucin production, particularly in mature goblet cells, indicating vulnerability of the mucus barrier. When challenged with dextran sulfate sodium (DSS), Becn1IEC+/- mice exhibited greater weight loss, higher disease activity, more severe histological colitis, and disproportionate loss of neutral mucins, with inflammation confined to the mucosa. Together, these findings show that BECLIN1 insufficiency does not trigger spontaneous inflammation but destabilises epithelial organisation and barrier defence, thereby sensitising the gut to inflammatory challenge and further positioning BECLIN1 as a threshold-dependent determinant of intestinal resilience.",

At present, most functional studies involving G4s have focused on cancer cells. This study investigated how neurons respond to genotoxic stress induced by quarfloxin (CX-3543), a small molecule that stabilizes G4s. We found that quarfloxin treatment induced DNA damage in neurons, with double-strand breaks enriched in the nucleolus. Proteomic analysis revealed that quarfloxin promoted substantial protein changes, affecting networks associated with Alzheimer's, Parkinson's, and Huntington's diseases, and amyotrophic lateral sclerosis. Among the affected proteins, the G4 helicase DDX3X, encoded on the X chromosome, was upregulated, prompting further investigation of DDX3X and its Y-linked homolog DDX3Y in male and female neurons, respectively. RNA sequencing identified DDX3X- and DDX3Y-regulated gene networks involved in DNA damage responses, inflammation, cell cycle regulation, and stress-associated pathways, with notable sex-dependent differences. In human brain tissue, DDX3X expression and nuclear enrichment were increased in neurons from older females compared to younger individuals, with further elevation observed in Alzheimer's disease. Taken together, these findings identify DDX3X and DDX3Y as modulators of neuronal stress responses downstream of G4 stabilization and indicate that their induction is accompanied by activation of DNA damage response genes, as well as cell cycle- and inflammation-associated pathways, suggesting that sustained activation of these pathways may disrupt neuronal homeostasis. Our study provides insight into G4-dependent stress mechanisms in neurons and highlights sex-linked pathways that may contribute to brain aging and neurodegenerative disease vulnerability.",

Weight management randomized controlled trials (RCTs) for adults with overweight/obesity that measured ED risk were systematically searched in four databases and two trial registries. A project-specific codebook was used to code 84 delivery features and 89 intervention strategies of trials. Individual strategies were grouped into 20 clusters which were further grouped into five broad categories. Trial investigators verified coding and narrative synthesis using descriptive statistics of findings was reported. Of 14,880 identified, 58 eligible trials were coded, of which 26 trials with 64 intervention arms were verified and therefore included. Intervention arms included a mean (SD) of 24 (11) intervention strategies. Commonly used intervention strategy clusters were nutrition education (91%), dietary behavior change strategies (84%), physical activity education (81%), and dietary self-monitoring (80%). Few interventions used strategies in the category of psychological components (13-41%). The median (range) intervention duration was 27 (4-104) weeks, and contacts with participants typically included a staged approach of weekly to monthly contact. Adult weight management interventions are multifactorial with varying delivery features and intervention strategies. Despite this, psychological (e.g. weight stigma) and sleep-health related strategies are either rarely used or are underreported. Breaking down intervention components using our framework can help identify which strategies influence outcomes, including eating disorder risk, and inform the design and reporting of future interventions. Some adults seeking weight management for obesity may have an eating disorder or disordered eating behaviors. Research shows most people who take part in behavioral weight management programs have an improvement in eating disorder symptoms, however a small number may experience worsening symptoms. In this study, we break down behavioral weight management programs that measure eating disorder risk to better understand the features they use. We found that these programs vary widely in the number and type of strategies they use, as well as in how they are delivered, such as the length of the program. Strategies that focus on psychological factors (for example, addressing weight stigma) and sleep health were rarely used or reported. These findings are useful in guiding the design and reporting of future behavioral weight management programs. They can also be used in future research to determine which specific program features improve or worsen outcomes such as eating disorder risk.",
"42310788": "ID: 42310788\nTitle: Co-development of a genetic care pathway for ALS: real-world perspectives from the North of England.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare, progressive neurodegenerative disorder, with a substantial proportion of cases attributed to genetic factors. Recent advances in gene discovery and genomic technologies have transformed ALS care by enabling genomic testing to inform prognosis, assess familial risk, and facilitate access to novel therapies. However, guidance on the delivery of genetic testing and counselling in ALS remains limited, leading to variability in clinical practice. In response, the Manchester Motor Neuron Disease (MND) Care Centre and the Manchester Centre for Genomic Medicine co-developed a structured genetic care pathway for ALS, drawing on real-world data, patient engagement, and multidisciplinary collaboration. A retrospective evaluation of 326 ALS patients at the Manchester MND Care Centre identified significant variability in genetic testing uptake, counselling practices, and record-keeping. Patient survey and engagement sessions revealed uncertainty regarding key genetic concepts and inconsistent recall of pre- and post-test discussions. Priorities for improvement included clearer communication, standardised discussions, and enhanced support for families following genetic findings. Consequently, the Greater Manchester ALS Genetic Testing Pathway was developed by a multidisciplinary team, incorporating consensus-based steps for patient identification, pre-test conversations, consent, testing, results disclosure, and post-test support. This pathway integrates genetic testing into routine ALS care, clarifies team responsibilities, and establishes a framework for ongoing evaluation using key performance indicators. Patient and staff feedback is used to support continuous improvement. The co-developed ALS genetic testing pathway provides a scalable model for standardising genomic care in mainstream clinical settings. By establishing clear processes for genetics discussions, consent, and follow-up, the pathway seeks to improve equity, transparency, and person-centred care. Ongoing evaluation and collaboration with patients, clinicians, and genetic services are essential to ensure the pathway remains responsive to scientific advances and evolving patient needs. Wider adoption of structured genetic pathways may facilitate the integration of genomics into care for rare diseases across healthcare systems.",

However, its diagnostic and prognostic value in other frontotemporal dementia (FTD) variants remains underexplored due to limited understanding of the underlying neural mechanisms. This study investigated whether ToM deficits are shared across the frontotemporal dementia spectrum and explored the functional connectivity alterations underlying these disturbances using resting-state functional magnetic resonance imaging. Sixty-seven FTD patients [14 non-fluent variant primary progressive aphasia (nfvPPA), 17 semantic variant primary progressive aphasia (svPPA), 23 bvFTD, 13 right temporal variant frontotemporal dementia (rtvFTD); 34 women; mean age 66.5\u202f\u00b1\u202f7.7 years] and two control groups (48 age-matched healthy controls; 50 young healthy controls) underwent clinical, neuropsychological and brain magnetic resonance imaging assessments. ToM was evaluated in patients using the Story-Based Empathy Task (SET), which includes the Story-Based Empathy Task affective subtest (SET-EA) and the Story-Based Empathy Task cognitive subtest (SET-IA). Resting-state functional connectivity networks were obtained in young healthy controls using seed-based analysis centred on the left medial prefrontal cortex for affective ToM and the right supramarginal gyrus for cognitive ToM. In addition, four large-scale functional networks were reconstructed to reflect disease-specific vulnerability. Functional brain connectivity within all networks was quantified using graph analysis and connectomics, and between-group comparisons were performed on both global and seed-based regional metrics. All patient groups showed similar impairments in affective and cognitive ToM performance. Network analyses revealed two dissociable but interconnected ToM systems. Global metrics of network topology indicated increased path length and reduced nodal strength in both ToM networks, particularly in bvFTD and nfvPPA patients (P\u202f<\u202f0.05). Direct seed-based connectivity analyses confirmed widespread functional connectivity reductions from key nodes (e.g. left inferior frontal gyrus, anterior cingulate cortex) in these groups. In contrast, svPPA and rtvFTD cases exhibited relatively preserved functional connectivity within ToM circuits. Correlation analyses revealed associations between cognitive ToM network metrics and global ToM performance, and between functional connectivity in the salience network and behavioural dysfunction. Affective and cognitive ToM abilities are comparably impaired across FTD variants, suggesting that socio-cognitive impairments may represent a core and early feature across the FTD spectrum. Such deficits are mirrored by patterns of functional disconnection within dedicated large-scale networks, with bvFTD and nfvPPA showing the most pronounced disruptions. This study underscores the diagnostic relevance of socio-cognitive markers and highlights their potential as clinical and biomarker targets in future therapeutic interventions.",
"42311464": "ID: 42311464\nTitle: GLP-1 Receptor Agonists in Neurological Disorders: From Mechanisms to Clinical Translation.\nAbstract: Glucagon-like peptide-1 receptor agonists, or GLP-1RAs, have been used for years to treat type 2 diabetes and obesity. More recently, it has become clear that these receptors are widely distributed throughout the central nervous system (CNS), which has raised the possibility of repurposing these drugs for neurological disorders. In this review we go through the evidence across a range of neurological conditions, discuss the main mechanisms thought to explain their neuroprotective effects, and point out the hurdles that still need to be cleared before they can be used in the clinic. Preclinical work has been fairly consistent. These drugs activate the cAMP/PKA/CREB pathway to boost BDNF expression. They also turn on the PI3K/Akt pathway, which reins in GSK-3\u03b2 and cuts down tau hyperphosphorylation. At the same time, they put the brakes on NLRP3 inflammasome activation in microglia and get AMPK dependent mitochondrial biogenesis and autophagy going. In animal models of Alzheimer's disease (AD), Parkinson's disease (PD), ischemic stroke, intracerebral hemorrhage (ICH), Huntington's disease (HD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), depression, epilepsy, and spinal cord injury (SCI), these cellular changes add up to less protein aggregation, less neuron loss, and better functional outcomes. Clinical data are harder to interpret. Some trials have shown modest improvements in cognition or motor function, but others have found no meaningful effect on disease progression. One thing that does not get enough attention is that different GLP-1 receptor agonists cross the blood-brain barrier at widely varying rates, and these differences could well explain why trial results have been so mixed. Looking ahead, getting these drugs into the clinic will depend on choosing the ones that actually reach the CNS, developing biomarkers that can predict who will respond, and designing trials that take disease heterogeneity into account. Seen this way, this review offers a practical framework for turning mechanistic insights into real patient benefit.",

Recent evidence highlights the importance of the nuclear factor erythroid 2-related factor 2 (NRF2) pathway, a key regulator of cellular defense mechanisms, in maintaining neuronal health and function. A narrative literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar to identify relevant experimental, clinical, and review studies on NRF2 signaling, physical exercise, oxidative stress, muscle-brain crosstalk, and neurodegenerative diseases. Keywords included \"NRF2\", \"Nrf2/Keap1/ARE\", \"physical exercise\", \"exercise-induced oxidative stress\", \"myokines\", \"exerkines\", \"Alzheimer's disease\", \"Parkinson's disease\", \"Huntington's disease\", and \"amyotrophic lateral sclerosis\". NRF2 modulates the expression of a variety of antioxidant and cytoprotective genes, contributing to the protection of neurons against oxidative stress, inflammation, and protein aggregation, processes central to the pathogenesis of neurodegenerative diseases. Additionally, physical activity has been identified as a powerful modulator of NRF2 activation, with exercise offering neuroprotective effects through the induction of NRF2-mediated pathways. This review explores the interplay between NRF2 activation and physical exercise in the context of neurodegenerative diseases, detailing the molecular mechanisms by which exercise influences NRF2 activity to combat cellular damage and enhance neuroprotection. We discuss the therapeutic potential of combining exercise regimens with NRF2-targeted therapies, highlighting the promise of this dual approach in slowing disease progression, improving cognitive function, and enhancing quality of life in affected individuals. Furthermore, we examine the challenges and future directions for clinical implementation, including optimal exercise protocols and the development of NRF2-based pharmacological interventions. This review underscores the importance of NRF2 as a central mediator of neuroprotection and the therapeutic promise of physical activity in the management of neurodegenerative diseases.",

Despite advances in understanding their multifactorial pathogenesis, current pharmacotherapies primarily provide symptomatic relief and fail to modify disease progression. This review critically evaluates the emerging role of bioactive phytocompounds as multi-target neuroprotective agents in the management of AD and PD, emphasizing mechanistic insights and translational challenges. A comprehensive literature search was conducted in PubMed, Scopus, and ScienceDirect, focusing on both preclinical and clinical studies that investigated the neuroprotective potential of key phytoconstituents, including luteolin, catechin, apigenin, and quercetin, derived from botanicals such as Commiphora wightii (Guggul), Curcuma longa, and Salvia officinalis. Accumulating evidence demonstrates that these phytoconstituents exert potent antioxidant, anti-inflammatory, anti-amyloidogenic, and anti-apoptotic effects. Mechanistically, they modulate critical signalling pathways implicated in neurodegeneration, including attenuation of oxidative stress, suppression of pro-inflammatory cytokines (e.g., TNF-\u03b1, IL-6), mitochondrial stabilization, inhibition of acetylcholinesterase activity, and prevention of amyloid-\u03b2 aggregation. Their pleiotropic actions position them as promising adjuncts or alternatives to current mono-targeted therapies. However, clinical translation remains constrained by poor bioavailability, lack of standardisation, and limited pharmacokinetic profiling. Phytocompounds show pleiotropic mechanisms (antioxidant, anti-inflammatory, anti-amyloidogenic) but clinical translation is limited by pharmacokinetic and standardisation barriers; novel delivery systems and rigorous clinical trials are required. Phytocompounds represent a compelling, multi-target strategy for AD and PD management, yet significant barriers to clinical application persist. Future research should focus on the development of advanced drug delivery platforms (e.g., nanoformulations), robust clinical trials, and standardized phytopharmaceutical preparations to validate efficacy and safety. Integrative therapeutic frameworks combining phytochemicals with existing pharmacotherapies may offer a viable path toward disease modification in neurodegeneration.",

The ubiquitin-proteasome system (UPS) serves as a neuroprotective quality control mechanism that clears aggregates. PML nuclear bodies (NBs) were proposed to serve as hubs for SUMO-primed ubiquitylation and degradation of misfolded proteins. Georgiadou et\u00a0al. provide evidence that an ALS-linked NEK1 truncation mutant is recruited to PML NBs, where it likely undergoes SUMOylation and ubiquitylation. In mice, PML loss exacerbates ALS-like symptoms, while induced PML expression delays disease onset. These findings establish PML as a key regulator of proteostasis and highlight PML induction as a potential therapeutic strategy for ALS and related proteinopathies.",

It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions. Moreover, conceptualizing neurodegeneration as a nutrient-sensitive, systems level disorder, propose a mechanistically informed and integrative approach that combine targeted nutritional strategies with pharmacological and lifestyle therapies to more effectively modify neurodegenerative trajectories.",

Conventional approaches rely on costly neuroimaging or invasive cerebrospinal fluid sampling, which limit accessibility and early intervention. Recent advances in 3D printing have enabled rapid prototyping of lab-on-chip (LOC) platforms that integrate microfluidics, biosensors, and biological models to detect disease-specific biomarkers with high sensitivity and throughput. Herein, we explore the synergistic role of 3D printing technologies and biomaterials in fabricating LOC systems for NDs. We highlight key biomarkers, and neuron- and organoid-on-chip platforms, and discuss the challenges and opportunities in clinical translation. By combining technical innovation in additive manufacturing with biological relevance, 3D-printed LOC devices represent a transformative approach toward precision diagnostics in neuro-medicine.",

ECAS-Cognitive and -Carer Interview (ECAS-C/-CI) scores of N\u2009=\u2009901 patients with ALS without a formal diagnosis of dementia were retrospectively retrieved. Patients were classified, pursuant to Strong et al.'s criteria, as cognitively and behaviourally normal (ALScbn), cognitively and/or behaviourally impaired (ALSci/bi/cbi), or Possible ALS-FTD, according the following ECAS-based algorithms: (1) Abrahams', solely addressing ECAS-C total and ALS-Specific subtotals; (2) Poletti et al.'s, addressing single task-level ECAS-C scores; (3) \"Subscale\", addressing ECAS-C subscales (i.e., Language, Executive, Fluency, Memory and Visuospatial). All algorithms relied on single-item-level ECAS-CI scores for behavioural classifications. Whilst agreement rates among these classifications were moderate to high (84-86%; Cohen's k\u2009=\u20090.78-0.81), and some discrepancies emerged: (1) \"ALScbn-to-ALSci\" and \"ALSci-to-ALScbn\" re-classifications occurred across the three comparisons, ranging from\u2009~\u200911% to\u2009~\u200924%; (2) the most classificatory disagreements (~\u200943%) occurred for the ALScbi category when comparing single task-level (Poletti) to total-level (Abrahams) algorithms, with patients being re-classified as either ALSbi or Possible ALS-FTD; (3)\u2009~\u200924% of Abraham's Possible ALS-FTD cases were re-classified as either ALScbi or ALSbi by the Subscale approach. Different ECAS-based algorithms for deriving Strong's phenotypes might yield slight discrepancies that could under- or overestimate a given classification.",
"42324254": "ID: 42324254\nTitle: Direct evidence of upper motor neuron excitability changes in a patient with ALS.\nAbstract: A key feature of amyotrophic lateral sclerosis (ALS) pathophysiology is motor neuron hyperexcitability. However, the mechanisms of hyperexcitability are not well understood. Prior studies have used transcranial magnetic stimulation (TMS) to demonstrate increased motor cortex excitability and reduced intracortical inhibition in human ALS. Yet, interpretation of these findings is limited because measurement of muscle responses cannot disentangle the specific contribution of upper and lower motor neurons and of cortical interneurons to excitability changes. We had the rare opportunity to record directly the corticospinal output evoked by TMS upstream of the spinal circuitry in a patient with ALS who had undergone epidural electrode implantation for intractable pain. Single-pulse stimulation was performed both with a coil orientation inducing a current that activates corticospinal neurons directly, and with a coil orientation inducing a current that activates corticospinal neurons trans-synaptically. Short-interval intracortical inhibition (SICI) was also studied using paired-pulse stimulation. Data obtained from the patient were compared with those recorded in 10 conscious control subjects. Compared with control subjects, patient showed a reduced amplitude in response to direct corticospinal neuron activation, yet an enhanced amplitude of corticospinal output after trans-synaptic corticospinal neuron activation, together with a SICI reduction. Present findings provide direct evidence of hyperexcitability of monosynaptic glutamatergic inputs to corticospinal neurons that, in association with reduced intracortical inhibition, can trigger neurodegeneration. Taken together with the extensive body of evidence generated by noninvasive TMS studies, the findings from this single-case study may provide valuable insights into the pathophysiological mechanisms of the disease.NEW & NOTEWORTHY The response evoked by direct activation of corticospinal neurons is reduced in human amyotrophic lateral sclerosis (ALS). In contrast, the response evoked by trans-synaptic activation of these cells is enhanced. The activity of inhibitory inputs to corticospinal neurons is reduced. These abnormalities related to abnormal excitatory and inhibitory input processing by corticospinal neurons may trigger neurodegeneration.",
"42324866": "ID: 42324866\nTitle: Muscle Ultrasound Is a Sensitive Outcome Measure in ALS.\nAbstract: Muscle ultrasound is a potential outcome measure in amyotrophic lateral sclerosis (ALS), although prospective, multicenter longitudinal studies are lacking. This study aimed to evaluate muscle ultrasound as an outcome in ALS and compare its sensitivity with clinical and neurophysiological metrics. In this prospective two-center cohort study, adults with ALS underwent baseline and follow-up assessments at least 3 months apart. Clinical measures included the ALS Functional Rating Scale-Revised (ALSFRS-R) and Medical Research Council sum scores. Median nerve abductor pollicis brevis and ulnar nerve first dorsal interosseous compound motor action potential (CMAP) amplitudes were recorded. Muscle ultrasound of 11 bulbar and limb muscles was performed using harmonized protocols, with offline analysis of muscle thickness and echogenicity. Longitudinal change and effect sizes were calculated. Twenty-two patients were included (median age 59.3\u2009years, follow-up 9.6\u2009months, disease duration 23.1\u2009months). ALSFRS-R declined by -3.0 points (-0.7% per month; effect size 0.84). Median nerve CMAP amplitude decreased by -1.6\u2009mV (-1.2% per month; effect size 0.77). Muscle echogenicity increased by 0.8\u2009units (+6.0% per month), yielding the largest effect size (1.09), with increases across multiple muscles. Responsiveness improved with onset-specific muscle selection, with biceps brachii (effect size 1.12) and gastrocnemius (1.18) showing the strongest changes. Muscle thickness and fasciculation frequency did not change. Muscle ultrasound echogenicity is a sensitive structural biomarker of ALS progression, demonstrating greater responsiveness than ALSFRS-R and CMAP over 3-12\u2009months. Its accessibility and sensitivity support its utility as an outcome measure in clinical trials.",

We developed an environmentally adjusted metabolic age score (EAmAge) to isolate intrinsic ageing biology relevant to neurodegeneration and chronic disease. Major environmental influences were statistically removed from plasma lipidomic profiles before constructing an age-prediction model using ridge regression. EAmAge was derived in the AusDiab cohort (n = 10,339) and validated across three independent cohorts (BHS, ADNI and ASPREE; total n = 9,835). Compared with an unadjusted lipidomic age model (mAge_orig), EAmAge showed stronger and more consistent associations with incident Alzheimer s disease-related dementia, cardiovascular events and all-cause mortality. EAmAge was also associated with Alzheimer s disease-related biomarkers, including amyloid burden, reduced glucose metabolism and hippocampal atrophy. These findings establish EAmAge as a robust and partially modifiable biomarker that improves risk stratification by disentangling intrinsic metabolic ageing from environmental confounding.",

Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique.",

We included observational studies that applied sEMG to individuals diagnosed with ALS, with or without comparison to healthy controls, and without restrictions on publication year. The analyses included signals recorded at rest and during voluntary contractions, with or without the use of biofeedback. Most studies employed conventional or high-density surface electrodes, with sampling frequencies ranging from 500 Hz to 3000 Hz. The results showed that the primary parameters assessed were muscle fatigue, fasciculation patterns, the number of motor units (MUNE/MUNIX), motor unit firing rates, and signal complexity. These parameters demonstrated sensitivity to disease progression and may contribute to early diagnosis, phenotypic stratification, and functional monitoring of ALS. Additionally, the studies highlighted the increasing use of advanced computational approaches, such as machine learning, for feature extraction and automated classification. In conclusion, sEMG is a promising tool for functional assessment in ALS, with the potential to improve diagnostic accuracy and support new therapeutic strategies based on electrophysiological biomarkers. However, despite technological advances, the included studies displayed substantial methodological heterogeneity and limited protocol standardization. Integration with other neurophysiological modalities also remains underexplored, despite its significant clinical potential.",

Model-system experiments generate interpretable gene networks but do not establish relevance to human disease. In contrast, statistical genetics identifies variant- and gene-level associations but cannot test mechanistic models. Here, we bridge these approaches by introducing NERINE, a hierarchical model-based rare variant association test that incorporates gene network topology while remaining robust to network inaccuracies. NERINE supports analysis of networks from established pathway databases and model-system screens. A comprehensive search across pathway databases reveals associations for breast cancer, cardiovascular diseases, and type 2 diabetes not detected by single-gene tests. Applied to experimental screen-derived networks in Parkinson's disease (PD), NERINE highlights autophagy-, vesicle-trafficking-, and protein-homeostasis-related gene modules. Genome-scale CRISPR interference (CRISPRi) screening in human neurons and NERINE converge on PRL, revealing an intraneuronal \u03b1-synuclein/prolactin stress response that may impact resilience to PD.",

They affect the central nervous system, including the brain-manifesting, for example, as dementia-as well as the retina, as seen in glaucoma or age-related macular degeneration. Malnutrition-defined as quantitative or qualitative under- or overnutrition-affects key mechanisms that contribute to neuronal and retinal neurodegeneration. OBJECTIVE: The aim of this study is to systematically present the pathophysiological mechanisms of malnutrition-related neurodegeneration, to evaluate the current evidence on dietary patterns and cognitive health, and to derive practical clinical strategies for nutritional optimization. METHODS: Narrative literature review based on peer-reviewed publications from the fields of nutritional medicine, geriatrics, neurology, ophthalmology, and public health. RESULTS: Malnutrition promotes oxidative stress, mitochondrial dysfunction, chronic neuroinflammation, and vascular dysregulation, and it influences neurotransmitter synthesis. These mechanisms are relevant to both cerebral and ocular neurodegenerative processes. The Mediterranean diet and the MIND diet are associated with a significantly reduced risk of cognitive impairment; for ocular diseases, interventional studies in age-related macular degeneration in particular demonstrate protective effects of antioxidant supplementation, whereas evidence for glaucoma is currently based predominantly on observational data. Screening approaches and micronutrient diagnostics enable early identification of at-risk individuals. Building on this, individualised dietary interventions and targeted supplementation of selected nutrients could be potentially preventive and stabilising therapeutic strategies. CONCLUSION: Malnutrition is a key modifiable risk factor for neurodegenerative diseases of the brain and retina. More intense integration of nutritional diagnostics and therapy into neurological, geriatric, and ophthalmological care structures appears warranted.

"42332177": "ID: 42332177\nTitle: Trace Elements Dyshomeostasis and Toxic Metals Neurotoxicity in Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, are defined by the progressive loss of neurons through interconnected pathological mechanisms, including oxidative stress, mitochondrial dysfunction, protein aggregation, and neuroinflammation. Accumulating evidence implicates metal dyshomeostasis as a central and multifaceted contributor to these mechanisms, with roles ranging from a primary pathogenic driver in AD and PD, to a secondary amplifier of genetic pathology in HD and ALS, and as a contextual risk modifier in the presence of toxic metals. Essential trace metals such as iron, zinc, copper, manganese, selenium, iodine, and molybdenum are vital for neurotransmission, antioxidant defense, and cellular metabolism. Dysregulation of these metals disrupts redox balance, impairs proteostasis, and activates regulated cell death pathways, including ferroptosis and cuproptosis. Toxic metals, such as lead, cadmium, and mercury, exacerbate neurodegeneration by displacing essential metals, inducing oxidative injury, and promoting protein misfolding and neuroinflammation. This narrative review synthesizes mechanistic, experimental, genetic epidemiological, and clinical evidence to critically evaluate the contributions of both essential and toxic metals to neurodegeneration in AD, PD, HD, and ALS. We examine the genetic, environmental, and physiological determinants of metal homeostasis; the analytical techniques for quantifying metals in clinical samples; and clinical trial data on metal-targeted therapeutic strategies. Notably, iron chelation with deferiprone consistently reduces brain iron on neuroimaging but worsens clinical outcomes in both PD and AD, presenting a translational paradox that requires mechanistic re-evaluation. We also provide methodological recommendations for interpreting Mendelian randomization studies of metal exposures and propose translational priorities to advance metal-targeted diagnostics and therapeutics for neurodegenerative diseases.",

Effective therapies capable of restoring host-pathogen balance remain limited, particularly in the context of multidrug-resistant strains. This study investigated the therapeutic efficacy of thymol in a murine model of K. pneumoniae-induced ALI. Oral thymol (5-20\u2009mg/kg) markedly reduced lung injury, suppressed leukocyte infiltration, improved pulmonary histoarchitecture, and significantly enhanced bacterial clearance. Thymol reshaped systemic and local immune responses by decreasing tumor necrosis factor-\u03b1 (TNF-\u03b1) and C-reactive protein (CRP), increasing interleukin-10 (IL-10), and limiting macrophage and granulocyte recruitment. Mechanistically, thymol attenuated heme peroxidase-driven oxidative stress, as evidenced by reduced myeloperoxidase (MPO) and eosinophil peroxidase (EPO) activities, decreased malondialdehyde (MDA), hydrogen peroxide (H2O2), and nitric oxide (NO), along with restoration of catalase activity and glutathione levels. Complementary in silico docking predicted stable interactions of thymol with MPO and EPO, as well as essential bacterial metabolic enzymes, including deoxy-D-xylulose-5-phosphate synthase (DXS), acetolactate synthase (ALS), and dihydrodipicolinate synthase (DHDPS). Collectively, these findings suggest that thymol may act as a multi-target bioactive compound capable of modulating host inflammatory and redox pathways while potentially impairing bacterial metabolic fitness, thereby mitigating pneumonia-associated ALI.",

The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech\u2011derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1\u2011weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.",

Aim of this study is to assess the tolerability, safety, and effectiveness of adding a sigh cycle to non-invasive mechanical ventilation (NIMV) settings in ALS patients. In this randomized, blind-controlled proof-of concept study, 44 consecutive ALS patients with indication for NIMV were randomized to: Group I: NIMV with Sigh cycles; Group II: NIMV without Sigh. The primary outcome was the reduction in the Oxygen Desaturation Index (ODI); secondary outcomes included: Overnight Oximetry (OvOx), Arterial blood gas (ABG), and Visual Analog Scale (VAS; 0-10) scores to assess sleep quality, symptom intensity, mask interface, and NIMV tolerance. Assessments were conducted at baseline, after NIMV adaptation (T1) and at 1-month follow-up (T2). The Sigh cycle was safe and well tolerated. No significant group differences were observed at T1 or T2 in the primary outcome ODI (median \u0394ODI: Group A:-4.2; Group B:-4.6: p\u2009=\u20090.54), as well as in the OvOx parameters and pO2 and pCO2 ABG values.

Although caregiver burden and perceived social support was conceptualized as an independent correlate of quality of life rather than a factor operating primarily through caregiver burden. This study examined these associations within a stress-process framework in which perceived social support was conceptualized as an independent correlate rather than a buffering factor. This cross-sectional analytical study included 118 informal caregivers of patients with ALS. Primary stressors were defined as patient functional status (ALSFRS-R), caregiving duration, and communication difficulty. Caregiver burden (Zarit Burden Interview) was considered a secondary stressor. Physical and mental quality of life were assessed using the SF-12, and perceived social support was measured with the Multidimensional Scale of Perceived Social Support. Hierarchical regression analyses were performed to examine associations specified in the conceptual model while controlling for caregiver sociodemographic and socioeconomic variables. Additional mediation analyses were conducted to examine whether caregiver burden mediated the relationship between perceived social support and quality of life. Poorer patient functional status was significantly associated with higher caregiver burden, whereas communication difficulty showed a positive but non-significant association after adjustment for caregiver characteristics. Caregiver burden showed negative associations with both physical and mental quality of life. Perceived social support remained positively associated with quality of life after adjustment for caregiver burden and contributed additional explained variance in the models. Mediation analyses showed no evidence that caregiver burden mediated the association between perceived social support and either physical or mental quality of life. The findings are consistent with a stress-process framework in ALS caregiving, in which caregiver burden represents a central factor statistically associated with both caregiving stressors and quality of life, while perceived social support shows an independent association with quality of life. These findings suggest that both caregiver burden and perceived psychosocial resources may be relevant to caregiver well-being, although causal and intervention-related implications require further investigation. Caring for a person with amyotrophic lateral sclerosis (ALS) is physically and emotionally demanding, and many caregivers experience reduced quality of life. Previous studies have examined caregiver burden and social support separately, but it is not well understood how these factors work together to influence caregivers\u2019 well-being. This study examines how disease-related challenges, caregiver burden, and perceived social support are connected, and how these factors jointly affect the physical and mental quality of life of ALS caregivers. The study tests a conceptual model proposing that caregiving challenges increase caregiver burden, which in turn affects quality of life, while perceived social support contributes directly to quality of life rather than simply reducing stress. Worse patient functioning and communication difficulties were linked to higher caregiver burden. Higher burden was associated with poorer physical and mental quality of life. Perceived social support remained positively related to quality of life even after accounting for caregiver burden. These findings suggest that improving social support and reducing caregiver burden are both important for maintaining quality of life among ALS caregivers.",

Vulnerable alpha motor neurons showed thousands of molecular changes, marking a transition into a distinct cell state we named \"disease-associated motor neurons\" (DMs). We identified transcription factor networks that govern how healthy cells transition into DMs and those associated with motor neuron subtype-selective vulnerability. Upregulation of DM-associated transcription factors in human motor neurons induced key features of DMs, demonstrating an active regulatory component. Human ALS spinal cord single-nucleus RNA sequencing data demonstrated conservation of the DM signature in alpha motor neurons, and human orthologs of regions differentially accessible in SOD1-G93A mouse motor neurons were enriched for ALS genetic risk variants. Together, these findings establish a conserved, genetically linked motor neuron signature in ALS.",

Patient-derived platforms have therefore emerged as increasingly important human-relevant complements to animal and molecular models. This Critical Perspective examines when patient-derived ALS models genuinely change therapeutic decision-making rather than merely add mechanistic insight. The authors then propose a heuristic framework based on disease-relevant phenotype recapitulation, capture of patient-to-patient heterogeneity, and generation of findings that influence therapeutic prioritization or clinical translation. Furthermore, the authors evaluate iPSC-derived motor neurons, directly reprogrammed neurons, glial co-cultures, organoids, neural networks, and organ-chip systems against these conditions, while also addressing aging fidelity, reproducibility, upper motor neuron modeling, and regulatory implementation. Patient-derived models are not yet standalone decision-grade tools for ALS drug development. Their present value lies in functioning as a human-biology filter for target discovery, reverse translation, biomarker development, and patient stratification when used within rigorous, standardized, and clinically linked workflows. The strongest current evidence supports proof-of-principle rather than generalized predictive validity.",

Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.",

During incremental workload exercise, femoral venous oxyhemoglobin (O2Hb) saturation exhibits a reproducible, momentary increase at the gas exchange threshold-coinciding with the inflection point of the in vivo O2 non-equilibrium curve (ONC). This suggests a transient shift in Hb's binding dynamics. We hypothesized that at this threshold, Hb tetramers carrying \u22641 bound O2 become predominant. In this state, the last bound O2 promotes further cooperative binding, but its release confers no cooperative advantage for unloading, biasing toward O2 rebinding. Using the O2 equilibrium curve models of Dash et al. (2016) and Adair, we computed the distribution of Hb's O2 ligation states across 12 pooled mean femoral venous blood samples from incremental workload cardiopulmonary exercise testing of five healthy male participants. At the gas exchange threshold-where the ONC inflects and flattens-tetramers with \u22641 O2 indeed dominated. This ligation-state distribution is consistent with Perrella et al.'s (1999) cryogenic resolution of native human Hb, which shows that carbon monoxide-ligated Hb tetramers peak at ~15-20% saturation, matching femoral venous ranges at the gas exchange threshold. Our results suggest that, at sufficiently low O\u2082Hb saturation, Hb may favor O\u2082 rebinding over cooperative unloading. We propose that glycolytic proton production and other Bohr effectors may counter this predicted binding bias supporting continued O\u2082 unloading. If confirmed, this mechanism unifies long-standing controversies in O2 transport physiology, framing the Hb-Bohr system as a proportional-integral controller of tissue oxygenation.",
"42341041": "ID: 42341041\nTitle: IRE1 regulates the proteostasis of TDP-43/TARDBP in ALS/FTD through ribosome-associated quality control.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are progressive neurodegenerative disorders characterized by motor neuron degeneration, leading to muscle weakness, atrophy, and cognitive impairments. A defining pathological hallmark of ALS/FTD is the cytosolic mislocalization and accumulation of TAR DNA-binding protein 43 (TDP-43), highlighting its critical role in ALS pathogenesis. However, the molecular mechanisms underlying TDP-43 proteostasis remain poorly understood. Through a genetic screening approach, we identify inositol-requiring enzyme 1 (IRE1), an endoplasmic reticulum-resident transmembrane protein, as a potent suppressor of TDP-43 protein levels. Furthermore, we show that ribosome-associated quality control (RQC) factors play a crucial role in regulating TDP-43 proteostasis and cellular toxicity. Activation of the RQC pathway prevents excessive accumulation of TDP-43 and associated toxicity. Mechanistically, our findings suggest that IRE1 regulates TDP-43 protein level by promoting the degradation of aberrant TDP-43 translation product through the RQC pathway. IRE1 acts canonically to enhance the transcription of the RQC core component Clbn/NEMF and noncanonically to physically interact with Clbn/NEMF, thereby ameliorating TDP-43-induced proteotoxicity. Moreover, ectopic expression or pharmacological activation of IRE1 alleviates TDP-43 pathology and restores cognitive function in the TDP-43 A315T ALS mouse models. Collectively, our study identifies a role for IRE1 in the translational quality control of TDP-43 and establishes its potential as a therapeutic target for ALS/FTD.",
"42341118": "ID: 42341118\nTitle: Isoform-specific steric zippers drive aberrant assembly and mislocalization of shortened TDP-43.\nAbstract: Prion-like domain (PrLD)-mediated aggregation and concomitant dysfunction of the essential RNA-binding protein transactive response (TAR) DNA-binding protein of 43 kilodaltons (TDP-43) is a common feature of multiple debilitating neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.",
"42341897": "ID: 42341897\nTitle: Programmed axon degeneration gene variants in human disease.\nAbstract: Programmed axon degeneration (PAD; also known as Wallerian degeneration) is a conserved pathway controlling axon breakdown following injury or metabolic stress. PAD is driven by the depletion of nicotinamide adenine dinucleotide (NAD) through loss of the pro-survival enzyme NMNAT2 and activation of the pro-degenerative NADase SARM1. Recent genetic studies have identified pathogenic variants in PAD pathway enzymes associated with severe neurodegenerative phenotypes. Pathogenic variants in NAMPT, NMNAT1, NMNAT2, and SARM1 have been identified and will be discussed in this review. NAMPT variants cause sensory and motor neuropathy with neurodevelopmental symptoms. NMNAT1 variants are well-characterized causes of Leber Congenital Amaurosis type 9, while NMNAT2 variants result in peripheral neuropathies with childhood onset. SARM1 gain-of-function variants with constitutively active NADase activity are enriched in amyotrophic lateral sclerosis patients. These findings demonstrate that maintaining proper NAD homeostasis is crucial for axon survival, and disruption through genetic variants leads to distinct neurodegenerative outcomes. Understanding these rare variants provides insight into PAD mechanisms and supports development of broad-spectrum neuroprotective therapies targeting this pathway. Current therapeutic approaches include SARM1 inhibitors in clinical trials, gene therapy, and NAD precursor supplementation, offering hope for treating multiple neurodegenerative diseases.",
"42343420": "ID: 42343420\nTitle: Immune checkpoint LAG-3 governs stage-dependent and disease-associated microglial modules in ALS model mice.\nAbstract: Immune checkpoint molecules, inhibitory receptors originally characterized in T cell biology, have recently emerged as regulators of microglial function in neurodegeneration, yet their roles in amyotrophic lateral sclerosis (ALS) remain unexplored. Here, we investigated LAG-3, an inhibitory immune checkpoint receptor, in microglial regulation during ALS pathogenesis using SOD1G93A mice. LAG-3 expression was progressively upregulated in spinal cord microglia during disease progression, and LAG-3-high microglia exhibited a disease-associated microglia (DAM) transcriptional signature. Genetic deletion of LAG-3 produced a biphasic phenotype, with accelerated disease onset but significantly prolonged disease duration. LAG-3 deficiency enhanced inflammatory microglial responses at the early disease stage, whereas at the late stage it suppressed inflammatory signaling while selectively preserving phagocytic effector gene expression, demonstrating that LAG-3 dissociates the inflammatory and phagocytic modules within the DAM program in a stage-dependent manner. These transcriptional changes translated into enhanced phagocytic capacity in primary microglia and amelioration of the spinal cord environment through suppression of inflammatory pathways and restoration of oxidative phosphorylation. Our findings identify LAG-3 as a stage-dependent regulator of microglial functional states in ALS and support the concept that immune checkpoint molecules constitute a class of module-level regulators of microglial function in neurodegeneration.",

Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1\u03b2, \u03b3 interferon (IFN-\u03b3), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1\u03b2, IFN-\u03b3, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1\u03b2 and IFN-\u03b3 decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1\u03b2,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice. The underlying mechanism may be related to attenuating neuroinflammation via the modulation of microglial activation mediated by TREM2. \u76ee\u7684\uff1a\u57fa\u4e8e\u9ad3\u6837\u7ec6\u80de\u89e6\u53d1\u53d7\u4f532\uff08TREM2\uff09\u4ecb\u5bfc\u7684\u5c0f\u80f6\u8d28\u7ec6\u80de\u6d3b\u5316\u89c2\u5bdf\u7535\u9488\u201c\u8db3\u4e09\u91cc\u201d\u5bf9\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u6a21\u578b\u5c0f\u9f20\u795e\u7ecf\u708e\u75c7\u7684\u5f71\u54cd\u3002 \u65b9\u6cd5\uff1a\u5c0636\u53eaSPF\u7ea7\u96c4\u6027\u4eba\u7a81\u53d8\u578b\u8d85\u6c27\u5316\u7269\u6b67\u5316\u91761\uff08SOD1-G93A\uff09\u8f6c\u57fa\u56e0\u5c0f\u9f20\u968f\u673a\u5206\u4e3a\u6a21\u578b\u7ec4\u3001\u7535\u9488\u7ec4\u3001\u836f\u7269\u7ec4\uff0c\u6bcf\u7ec412\u53ea\uff1b\u9009\u53d612\u53ea\u540c\u7a9d\u91ce\u751f\u5c0f\u9f20\u4f5c\u4e3a\u5bf9\u7167\u7ec4\u3002\u7535\u9488\u7ec4\u4e8e\u201c\u8db3\u4e09\u91cc\u201d\u8fdb\u884c\u7535\u9488\u5e72\u9884\uff0c\u91c7\u7528\u65ad\u7eed\u6ce2\uff0c\u9891\u738715 Hz\uff0c\u6bcf\u6b2110 min\uff0c\u9694\u65e51\u6b21\uff0c\u6bcf\u54683\u6b21\uff0c\u51714\u5468\uff1b\u836f\u7269\u7ec4\u4e88\u5229\u9c81\u5511\u6eb6\u6db2\uff088 mg/kg\uff09\u704c\u80c3\uff0c\u6bcf\u65e51\u6b21\uff0c\u51714\u5468\u3002\u5e72\u9884\u7ed3\u675f\u540e\uff0c\u5e94\u7528\u8f6c\u68d2\u6d4b\u8bd5\u4e0e\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u8bc4\u4f30\u5404\u7ec4\u5c0f\u9f20\u884c\u4e3a\u5b66\uff0cHE\u67d3\u8272\u548c\u5c3c\u6c0f\u67d3\u8272\u89c2\u5bdf\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u5f62\u6001\uff0c\u514d\u75ab\u8367\u5149\u6cd5\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\uff0cWestern blot\u6cd5\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u7ec4\u7ec7\u767d\u7ec6\u80de\u4ecb\u7d20\uff08IL\uff09-1\u03b2\u3001\u03b3\u5e72\u6270\u7d20\uff08IFN-\u03b3\uff09\u3001IL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u68c0\u6d4b\u5404\u7ec4\u5c0f\u9f20\u810a\u9ad3\u7ec4\u7ec7\u5355\u7ec6\u80de\u60ac\u6db2CD86+\u548cCD206+\u7ec6\u80de\u6bd4\u4f8b\u3002 \u7ed3\u679c\uff1a\u4e0e\u5bf9\u7167\u7ec4\u6bd4\u8f83\uff0c\u6a21\u578b\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u6392\u5217\u7d0a\u4e71\uff0c\u51fa\u73b0\u6838\u56fa\u7f29\u3001\u80de\u4f53\u76b1\u7f29\u7b49\u73b0\u8c61\uff1b\u8f6c\u68d2\u6d4b\u8bd5\u6f5c\u4f0f\u671f\u548c\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u6389\u843d\u65f6\u95f4\u7f29\u77ed\uff0c\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u3001IFN-\u03b3\u3001IL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7\u5355\u7ec6\u80de\u60ac\u6db2CD86+\u3001CD206+\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8\uff08P<0.01\uff09\u3002\u4e0e\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0c\u7535\u9488\u7ec4\u548c\u836f\u7269\u7ec4\u5c0f\u9f20\u810a\u9ad3\u524d\u89d2\u8fd0\u52a8\u795e\u7ecf\u5143\u6392\u5217\u8f83\u89c4\u6574\uff0c\u6838\u56fa\u7f29\u53ca\u5c3c\u6c0f\u5c0f\u4f53\u6eb6\u89e3\u4e22\u5931\u73b0\u8c61\u6539\u5584\uff0c\u795e\u7ecf\u5143\u7ed3\u6784\u5b8c\u6574\u6027\u63d0\u9ad8\uff1b\u8f6c\u68d2\u6d4b\u8bd5\u6f5c\u4f0f\u671f\u548c\u94a2\u4e1d\u60ac\u6302\u6d4b\u8bd5\u6389\u843d\u65f6\u95f4\u5ef6\u957f\uff0c\u810a\u9ad3\u524d\u89d2TREM2\u8367\u5149\u5f3a\u5ea6\u964d\u4f4e\uff0c\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u3001IFN-\u03b3\u86cb\u767d\u8868\u8fbe\u964d\u4f4e\uff0cIL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0c\u810a\u9ad3\u7ec4\u7ec7CD86+\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e\uff0cCD206+\u7ec6\u80de\u6bd4\u4f8b\u5347\u9ad8\uff08P<0.01\uff0cP<0.05\uff09\u3002\u4e0e\u836f\u7269\u7ec4\u6bd4\u8f83\uff0c\u7535\u9488\u7ec4\u810a\u9ad3\u7ec4\u7ec7IL-1\u03b2\u86cb\u767d\u8868\u8fbe\u5347\u9ad8\uff0cIL-4\u3001IL-10\u86cb\u767d\u8868\u8fbe\u964d\u4f4e\uff0cCD206+\u7ec6\u80de\u6bd4\u4f8b\u964d\u4f4e\uff08P<0.05\uff09\u3002 \u7ed3\u8bba\uff1a\u7535\u9488\u201c\u8db3\u4e09\u91cc\u201d\u5bf9SOD1-G93A\u8f6c\u57fa\u56e0\u5c0f\u9f20\u8fd0\u52a8\u529f\u80fd\u5177\u6709\u4e00\u5b9a\u7684\u6539\u5584\u4f5c\u7528\uff0c\u5176\u4f5c\u7528\u673a\u5236\u53ef\u80fd\u4e3a\u8c03\u63a7TREM2\u4ecb\u5bfc\u7684\u5c0f\u80f6\u8d28\u7ec6\u80de\u6d3b\u5316\uff0c\u8fdb\u800c\u6539\u5584\u795e\u7ecf\u708e\u75c7\u3002.",

A scoping review.\nAbstract: Aqueous formaldehyde (FA) solution, known as formalin, is currently the primary agent used for preserving tissue samples and anatomical specimens. Formaldehyde is widely used in laboratories and the chemical industry; it also occurs as an air pollutant and endogenous cellular metabolite. The potential carcinogenic effects of formalin on the respiratory tract are well documented. A less recognized consequence of occupational exposure to FA is its detrimental effect on the central nervous system (CNS) and brain function. A literature review was conducted to investigate the effects of FA on the brain. Five databases were searched: PubMed, Web of Science (WoS), Embase, ScienceDirect, and Google Scholar. To describe the effects of FA exposure and endogenous FA generation, 35 relevant publications were collected and analyzed. The literature review demonstrated that inhalation is the most common route of FA exposure. Several studies have shown that FA may cause hippocampal damage, disrupt melatonin secretion, and induce a wide range of cognitive disorders with varying characteristics and severity. These disorders include memory impairment, disturbances in balance and spatial orientation, learning difficulties, sleep disturbances, impaired judgment, and prolonged reaction times to stimuli. Increased endogenous FA concentration has also been associated with a higher risk of neurodegenerative diseases, such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis. The literature analysis demonstrated the high neurotoxicity of FA, which may lead to numerous neuropsychiatric disorders. We aim to draw attention to the risks associated with the routine use of formalin, particularly among anatomists and pathologists, and to encourage consideration of less harmful alternative preservation agents.",
"42347120": "ID: 42347120\nTitle: RNA-Binding Proteins in Ageing and Age-Related Disease.\nAbstract: RNA-binding proteins (RBPs) are essential regulators of all aspects of RNA metabolism, including splicing, stability, localisation, translation, and degradation. Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.",

Although several quantitative MRI (qMRI) parameters have been investigated individually, their respective diagnostic and clinical relevance remains unclear. Twenty-eight CIDP patients (21 typical, 7 multifocal) were prospectively enrolled and compared with 13 age- and sex-matched healthy controls and 17 patients with symptomatic hereditary transthyretin amyloid neuropathy (vATTR). All participants underwent 1.5\u2009T qMRI of the sciatic and tibial nerves and of the thigh and leg muscles. Nerve and muscle volume, magnetization transfer ratio (MTR), fat fraction (FF), and T2 relaxation time were extracted. Clinical assessment included ONLS, RODS, and MRC sum score, while electrophysiological evaluation included fibular compound motor action potentials and tibialis anterior MUNIX. Imaging parameters were compared between groups and correlated with clinical and neurophysiological measures. CIDP patients showed significant differences compared with controls in both nerve and muscle metrics. Nerve volume was increased and MTR decreased at both sciatic and tibial levels (p\u2009<\u20090.005). At the muscle level, leg muscles showed increased fat fraction and decreased MTR, while T2 values and muscle volume did not differ significantly. MTR showed the strongest correlations with disability scores and MUNIX. Compared with vATTR patients, CIDP patients had lower sciatic nerve MTR, whereas vATTR patients exhibited larger nerve volumes and more pronounced muscle abnormalities. Nerve volume appears to be a sensitive diagnostic marker, while MTR may reflect disease burden. A multiparametric qMRI approach may improve diagnosis and monitoring in CIDP.",

While side effects are typically mild, rare neurological complications have been reported. This is a case series of ten patients who reported of persistent fasciculations after COVID-19 vaccination. Methods: We describe the clinical presentation and diagnostic work-up of ten patients with new-onset fasciculations in temporal proximity to COVID-19 vaccination. Patients with prior SARS-CoV-2 infection or known alternative causes of fasciculations were excluded. Routine clinical data, including neurological examination, laboratory results, and electrophysiology (electromyography and nerve conduction studies), were analyzed. Results: Ten patients (5 male, 5 female; mean age 42.4 years) reported fasciculations beginning within 6 h to 13 days post-vaccination and persisting for 2-12 months at the time of presentation. Fasciculations were accompanied by additional symptoms such as paresthesia and fatigue. Laboratory results were mostly unremarkable; two patients had positive myositis antibodies without clinical correlates. Electrophysiology was unremarkable in six patients, while fasciculation potentials were detected in four patients. Nine were diagnosed with probable benign fasciculation syndrome (BFS), and one met diagnostic criteria for amyotrophic lateral sclerosis (ALS). Discussion: In this small, retrospective case series, most cases of post-vaccination fasciculations were benign and compatible with BFS. Whether BFS onset was causally linked to vaccination or due to a nocebo effect remains unclear. One patient was diagnosed with ALS, though a causal link remains speculative given the study's limitations and rarity of similar reports. Larger, prospective studies are needed to validate these observations and explore underlying pathophysiological mechanisms.",

The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.",

Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved \u03b1-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.",

Patient responses to treatments vary widely, highlighting the need for personalized care. Clustering patients based on disease progression could improve prognosis, guide clinical decision-making, and optimize clinical trial design. This study aimed to identify robust ALS patient clusters using ALS Functional Rating Scale-Revised (ALSFRS-R) scores and to determine diagnostic parameters predictive of cluster membership, enabling earlier stratification and targeted management. Data from the Tours ALS center registry (April 1997-October 2023) were analyzed; after preprocessing, 353 patients monitored every three months between January 2004 and July 2023 with ALSFRS-R, clinical, biological, and demographic data were retained. After preprocessing to handle missing or aberrant data, a weakly supervised approach labeled patient pairs based on their ALSFRS-R sequences. These labels were used to train a classifier to learn a distance for off-the-shelf clustering algorithms. Multiple configurations were tested, varying clustering algorithms, dimensionality reduction method, and number of clusters. Random Forest (RF) model predicted cluster membership from diagnostic parameters. Optimal clustering was selected using silhouette score, validated with Kaplan-Meier survival analysis. Stability and robustness were assessed with the Adjusted Rand Index (ARI) and silhouette score respectively. Predictive performance was evaluated using specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV). Diagnostic parameters associated with clusters were identified using Kruskal-Wallis and chi-squared tests for continuous and categorical variables. Three clusters (n\u2009=\u2009139, 121, 93) were identified, demonstrating strong separation (silhouette\u2009\u2248\u20090.6) and high stability of results (ARI\u2009\u2248\u20090.7). Survival differed significantly among clusters: over 50% of patients in the third cluster survived beyond 50 months, compared to less than 25% in the other clusters. Thirteen diagnostic parameters-including ALSFRS-R subscores, IgG levels, albumin quotient, and time to diagnosis-were key predictors of cluster membership. Cluster prediction achieved specificity and NPV\u2009\u2248\u20090.75, with close sensitivity and PPV compared to state-of-the-art methods. This framework successfully stratifies ALS patients into clinically meaningful clusters, revealing underlying disease heterogeneity and providing strong prognostic insight. Such classification can facilitate personalized care, guide therapeutic decisions, and inform the design of targeted interventions to improve outcomes. Not applicable.",
"42351263": "ID: 42351263\nTitle: Dynamic integration of skeletal muscle signals via extracellular vesicles in motor neuron diseases.\nAbstract: Extracellular vesicles (EVs) are heterogenous lipid bilayer-enclosed particles secreted by virtually all cell types. They encapsulate a diverse array of bioactive molecules, including proteins, lipids, nucleic acids, and metabolites, which can be transferred to recipient cells, thereby modulating their function and phenotype. In recent years, skeletal muscle-derived EVs (SkM-EVs) have emerged as key players in the bidirectional communication between skeletal muscle and motor neurons, contributing to the establishment and maintenance of neuromuscular homeostasis. Disruptions in this intercellular signalling have been implicated in the pathophysiology of motor neuron diseases (MNDs) such as spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS). In these contexts, SkM-EVs may contribute to disease progression by delivering pathogenic cargo, including misfolded proteins and aberrant RNAs, to motor neurons. A comprehensive understanding of SkM-EV biology, particularly their roles in neuromuscular communication, could offer critical insights into disease mechanisms and identify novel opportunities for biomarker discovery and therapeutic intervention. This review synthesizes current knowledge on the functional roles of SkM-EVs in motor neuron health and disease and evaluates their potential as diagnostic tools and therapeutic vectors in the context of MNDs.",
"42351313": "ID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.",

Here, we review how extracellular phosphoglycerate kinase 1 (ePgk1) improves neurite outgrowth of MNs (NOMN) and axonal growth, both in vitro and in vivo. Our group first elucidated a novel non-canonical function of ePgk1 as a cross-tissue mediator between nerve and muscle tissues. We then discovered that neural membranous Enolase 2 (Eno2) serves as a receptor of ligand ePgk1 and that ePgk1-Eno2 interaction suppresses the Rac1-GTP/p-Pak1-T423/p-P38-T180/pMK2-T334/p-Limk1-S323 axis, reducing p-Cofilin and promoting NOMN and axonal growth, finally suggesting that the 419th aspartic acid residue of Eno2 mediates this interaction. In a crucial preclinical step, we truncated two short 16-amino-acid derivatives from Pgk1, FD-1/-2, each mediating neuroprotection comparable to that of full-length 417-amino-acid Pgk1 in ALS animal models, in terms of improvements of innervated neuromuscular junction, MN cell bodies, motor performance, and endpoint prolongation. In this context, we also discuss the opposite function driven by Eno1-plasminogen interaction and by Eno2-ePgk1 interaction; the latter results in unfavorable for tumorigenesis. Unlike intracellular Pgk1 roles, ePgk1 is an extracellular factor with anti-angiogenic properties, further positioning ePgk1 and its FD-1/-2 as promising protein/peptide drugs for ALS treatment.",
"42352579": "ID: 42352579\nTitle: Transcranial Focused Ultrasound Stimulation for Alzheimer's Disease-A Scoping Review.\nAbstract: Background/Objectives: Alzheimer's disease (AD) remains a significant global health challenge, characterised by a persistent resistance to traditional pharmacological interventions. While non-invasive brain stimulation (NIBS) techniques like transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) show therapeutic promise, their limited depth of penetration restricts their efficacy in targeting deep-brain AD pathology. Transcranial focused ultrasound stimulation (tFUS) has emerged as a novel, non-invasive neuromodulatory tool capable of precise deep-brain targeting. This scoping review aims to systematically map the current evidence base regarding the neuromodulatory application of tFUS in AD. Methods: Following PRISMA-ScR guidelines, a scoping search was conducted across four major databases (Ovid MEDLINE, Embase, Web of Science, and CENTRAL). Studies were included if they investigated focused ultrasound stimulation (FUS) as a neuromodulatory intervention for AD, excluding applications involving blood-brain-barrier disruption via microbubbles. Two independent reviewers performed screening and data extraction, with inter-rater reliability assessed via Cohen's kappa. Results: Our analysis indicates that tFUS represents a safe and potent multi-modal intervention for AD that addresses both pathological protein aggregation and electrophysiological network failure. Its ability to modulate neuroplasticity and metabolic recovery suggests a promising therapeutic trajectory. Conclusions: Future research should prioritise the standardisation of acoustic protocols and the pursuit of longitudinal clinical cohorts to establish the long-term efficacy of this non-invasive technology.",
"42352907": "ID: 42352907\nTitle: The Dual Role of Glial Extracellular Vesicles in Neurodegeneration: Insights from iPSC-Based Models.\nAbstract: Extracellular vesicles (EVs) have emerged as key mediators of intercellular communication in the brain, with glial cell-derived EVs increasingly recognized for their roles in maintaining brain homeostasis and contributing to the progression of neurodegenerative diseases. By transferring a diverse cargo of bioactive molecules, including proteins, RNAs, and organelles, EVs influence recipient cell behavior and overall brain function. In neurodegenerative conditions, glial EVs can either propagate pathogenic signals or deliver neuroprotective and regenerative cues, depending on their cellular origin and molecular composition. This context-dependent heterogeneity highlights the need for physiologically relevant human models to investigate EVs biology. Human induced pluripotent stem cell (iPSC)-derived glial models provide a disease-relevant platform, as they recapitulate key pathological features of Alzheimer's disease (AD), Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). When further integrated with brain organoid platforms, these iPSC-based systems enable the generation of three-dimensional environments that closely resemble in vivo EVs dynamics. Importantly, glial EVs can modulate cellular pathways involved in neuronal survival and function. Indeed, their potential to interact with and, under specific experimental conditions, traverse the blood-brain barrier (BBB) has contributed to growing interest in their application for biomarker discovery and therapeutic development. Engineered and patient-specific EVs derived from iPSCs are emerging as promising tools for targeted, cell type-specific, therapeutic approaches, although their clinical applicability still requires further validation. This review discusses the emerging evidence supporting the dual role of iPSC-derived glial EVs in health and disease, underscores the translational potential of iPSC-based platforms for mechanistic studies, and outlines their promise as precision medicine tools for diagnostics and therapy.",
"42353064": "ID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype \u00d7 treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.",

Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown.

Depending on the TTR genotype, ATTR is classified as hereditary ATTR (ATTRv) with pathogenic gene variants and wild-type ATTR (ATTRwt) with a normal TTR genotype. Two cardinal clinical manifestations of ATTR are amyloid cardiomyopathy and peripheral neuropathy, but multisystemic deposition of amyloid may also manifest with ocular and leptomeningeal amyloidosis, various orthopedic complications (carpal tunnel syndrome, spinal stenosis), nephropathy, and gastrointestinal and pulmonary amyloidosis. The natural history of untreated ATTR is characterized by progressive worsening and 25% of patients may die within 24 months from the onset. The first treatment for ATTR was liver transplantation which slows the disease progression, but its use was limited by the scarcity of available liver allografts and complex post-transplant morbidities associated with immunosuppression and various metabolic disturbances. Recent introduction of TTR stabilizers and gene silencing has significantly changed the outcomes and reduced ATTR-related morbidities and mortality, and early diagnosis remains important for improved outcomes. In our narrative expert review, we are discussing epidemiological and clinical features of ATTR, its pathophysiology and available treatments as rapidly progressive fatal disease is being transformed into a treatable chronic disease.",

Several disease-modifying therapies have been developed to target neuroinflammatory pathways in specific disorders. However, their ability to stop disease progression or restore neuronal and mitochondrial homeostasis remains limited. This is still a major unmet clinical need. In this context, mesenchymal stromal cell (MSC)-derived Extracellular Vesicles (EVs) have emerged as a promising cell-free therapeutic strategy due to their ability to modulate immune responses and promote neuroprotection through the delivery of bioactive cargo. Recent evidence has identified a distinct subset of EVs, known as mitochondrial EVs (mito-EVs), which carry mitochondrial DNA, proteins, and functional components. These vesicles may uniquely influence cellular bioenergetics, redox balance, and neuroinflammatory signaling, offering additional therapeutic potential compared to conventional MSC-EVs. This review summarizes the role of MSC-derived EVs in neuroinflammatory disorders, with a particular focus on mito-EVs. It also discusses preconditioning strategies to enhance EV efficacy, including hypoxic, inflammatory, pharmacological priming and genetic engineering approaches. Finally, we critically evaluate current preclinical evidence regarding the treatment of major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Multiple Sclerosis, and Amyotrophic Lateral Sclerosis, as well as Traumatic Injury, highlighting the key challenges for clinical translation.",

Among these, ICI-related myocarditis, myositis and myasthenia gravis (MMM) overlap syndrome (ICI-MMM) is a rare but potentially fatal complication. Conventional immunotherapy often exhibits limited efficacy against ICI-MMM, which is associated with high mortality rates. Thus, there is an urgent need for novel and effective strategies to mitigate its life-threatening outcomes. We conducted a retrospective analysis of the successful rescue use of eculizumab in a patient with tislelizumab-related MMM overlap syndrome who tested seropositive for both anti-acetylcholine receptor (AChR) and anti-titin antibodies. We also performed a focused systematic literature review on the use of complement inhibitor therapy for ICI-related myasthenia gravis and its overlap syndrome. A 64-year-old male developed ptosis and tetraparesis two weeks following the second infusion of tislelizumab for lung adenocarcinoma. Serological testing revealed dual positivity for anti-AChR antibody and anti-titin antibody. Tislelizumab was immediately withdrawn, and the patient was treated with corticosteroids and intravenous immunoglobulin as first-line therapy. However, his clinical condition deteriorated rapidly, and new symptoms emerged, including chest pain, muscle pain, dysphagia, slurred speech, and dyspnea. Although the absence of histopathological confirmation for myocarditis and myositis, the clinical, laboratory, electrophysiological, and cardiac imaging findings supported the diagnosis of probable ICI-MMM. Rescue therapy with eculizumab was commenced (900 mg weekly for four doses), eliciting rapid and marked clinical improvement. The patient ultimately achieved minimal symptom expression without any exacerbation. This is the first reported case of successful eculizumab rescue treatment for probable tislelizumab-related MMM overlap syndrome with dual seropositivity. Our finding suggests eculizumab may represent a promising rescue option for ICI-MMM warranting prospective evaluation.",

Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.",

Accurate and accessible blood-based diagnostics for neurodegenerative diseases, including ALS, are being progressively required. Although blood cell gene expression profiles have potential clinical utility for distinguishing ALS, robust transcriptomic biomarkers for supportive diagnosis have not yet been established. Here, we analyzed publicly available peripheral blood mononuclear cell (PBMC) transcriptomic data from ALS patients using Maximum Mean Discrepancy, a kernel-based method that captures nonlinear distributional differences in a reproducing kernel Hilbert space and enables the extraction of informative gene combinations while minimizing multicollinearity, a common issue in multiple regression models. Using this approach, we identified a nonlinear three-gene combination-PRKAR1A, QPCT, and TMEM71-that distinguished ALS from healthy controls with an area under the curve (AUC) of 0.83 in a public PBMC dataset. This achievement was confirmed in laboratory PBMC samples with an AUC of 0.85, supporting the robustness of the identified gene signature in independent samples. Furthermore, these genes also enabled ALS classification in induced pluripotent stem cell-derived motor neurons with an AUC of 0.79. Knockdown of PRKAR1A, QPCT, or TMEM71 in motor neurons increased the TDP-43 expression levels, and PRKAR1A knockdown induced the mislocalization of TDP-43, accompanied by phosphorylation, suggesting a potential link to ALS-related pathophysiology. These findings suggest that nonlinear gene combinations may provide a useful strategy for identifying blood-based biomarkers and offer insights into ALS pathogenesis. This nonlinear, data-driven analytical framework enabled the transition from unbiased gene discovery to the identification of pathophysiology-associated molecules by in vitro functional validation.",

Autonomic disturbances, particularly cardiac dysautonomia, significantly impact patient outcomes, contributing to increased cardiovascular risks and mortality rate. While the ALS Functional Rating Score-Revised (ALSFRS-R) measures functional decline as disease progress, it overlooks autonomic criteria - a critical factor in ALS progression. This review aims to analyze noninvasive applications of cardiovascular signal variability for continuous real-time monitoring of autonomic dysfunction in ALS, while addressing gaps in current clinical assessments. A total of 584 literatures were gathered from four databases (WoS, PubMed, Science Direct and MEDLINE EBSCOhost) - published from inception till December 2023. 21 peer-reviewed studies were included in this review after screening and meeting the inclusion criteria. Various cardiovascular signal variability metrics and autonomic protocols were discussed. Key findings highlight cardiac autonomic dysfunction in ALS is marked by reduced heart rate variability, absent blood pressure regulation upon orthostatic stress and circadian changes, prolonged QTc interval and low baroreflex sensitivity. Moreover, increased autonomic burden is associated with a shift from sympathetic to parasympathetic dysregulation as the disease progresses. Evidence highlights the need to integrate noninvasive autonomic biomarkers into digital ALS monitoring frameworks, enabling earlier detection of autonomic involvement and more precise longitudinal monitoring beyond motor decline.",

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.",

Dieser narrative \u00dcbersichtsartikel auf der Grundlage von Leitlinien und Expertenkonsens wird unterst\u00fctzt durch eine Literaturrecherche auf PubMed (2000\u20132026). Die zitierten Studien stellen nach Meinung der Autoren die relevanten Arbeiten hierzu dar und wurden ausgew\u00e4hlt, um Entwicklungen und prinzipielle Konzepte zu veranschaulichen, beanspruchen jedoch keine Vollst\u00e4ndigkeit. Der PSA-Wert (prostataspezifisches Antigen) und die MRT liefern nicht nur Hinweise auf ein Prostatakarzinom, sondern auch auf andere urologische Erkrankungen wie Miktionsbeschwerden oder Testosteronmangel. Parallel zu anderen Fr\u00fcherkennungsuntersuchungen k\u00f6nnte der PSA-Wert mit 45\u201350\u00a0Jahren als einfaches Triage-Tool fungieren, um risikoadaptierte Verlaufskontrollen sowie fachurologische Vorstellungen zu steuern. Lebensstilfaktoren wie Bewegung, eine gesunde Ern\u00e4hrung und Beckenbodentraining k\u00f6nnen urologische Erkrankungen und deren Folgen positiv beeinflussen. Durch eine organisierte Prostatakarzinomfr\u00fcherkennung kann das karzinomspezifische Mortalit\u00e4t bereits heute vergleichbar zur Mammographie verbessert werden, durch ein holistischeres Herangehen kann der Gesamtnutzen jedoch noch mehr gesteigert werden. Die Urologie hat gro\u00dfe Chancen, die Gesundheitskompetenz des alternden Mannes, aber auch Fr\u00fcherkennungsma\u00dfnahmen f\u00fcr andere Erkrankungen, aktiv zu f\u00f6rdern. Die organisierte Prostatakarzinomfr\u00fcherkennung k\u00f6nnte hierf\u00fcr einen sinnvollen Einstieg darstellen. Moderne Fr\u00fcherkennungskonzepte sollten die ganzheitliche Gesundheitsf\u00f6rderung des alternden Mannes neben direkten onkologischen Endpunkten miteinbeziehen.",

Although these disorders are primarily driven by disease-specific genetic and proteopathic mechanisms, increasing evidence suggests that secondary mitochondrial DNA (mtDNA) damage and heteroplasmy shifts may exacerbate bioenergetic failure and neuronal vulnerability. Distinguishing primary disease mechanisms from downstream mtDNA alterations is critical to accurately evaluate emerging therapeutic strategies. Recent advances in mtDNA-targeted genome editing have enabled the direct manipulation of mitochondrial genomes. Mitochondrially targeted zinc finger nucleases and TALENs can selectively alter mutant mtDNA to induce heteroplasmy shifts, whereas DddA-derived cytosine base editors allow precise base editing without double-strand breaks. However, each platform has distinct limitations related to the target scope, off-target risk, design complexity, and delivery efficiency. The application of CRISPR/Cas-based systems to mammalian mtDNA remains constrained by the unresolved challenges in guiding RNA import. This review critically examines mitochondrial dysfunction and mutant\u00a0mtDNA accumulation in neurodegenerative diseases. It also evaluates current and emerging mtDNA-editing techniques, and highlights key translational barriers. We highlighted that mtDNA-targeted interventions can be a promising approach for\u00a0disease-modifying or adjunctive strategies, rather than curative approaches.",

Most existing artificial intelligence models for PD detection are trained on participants in well-resourced settings with confirmed clinical diagnoses. However, specialist-confirmed labels are often infeasible in low-resource settings. We developed a web platform for structured mouse data collection through pattern tracing tests. We sought to assess the feasibility of leveraging data from a community-recruited sample of participants with suspected but undiagnosed PD to train artificial intelligence models that achieve respectable performance in predicting diagnosed PD. We tested whether using weaker diagnostic labels that may be more feasible to collect in community or global health settings, where access to professional neurologists is sparse or nonexistent, can lead to models that learn predictive signals that are diagnostically useful. 261 participants (73 self-reported PD, 155 non-PD, and 33 suspected PD) were recruited from community organizations in Hawaii and completed 3 pattern tracing tasks on our custom web assessment: straight line, sine wave, and spiral wave. During each task, cursor positions, screen dimensions, and an in-target boolean flag were recorded. From these data, we engineered features and generated mouse trace images. We built 3 categories of classifiers: (1) a feed-forward neural network using engineered features, (2) fine-tuned computer vision deep learning models, and (3) multimodal models concatenating a feed-forward neural network with computer vision models. Performance was evaluated using 1 primary experiment and 2 secondary analyses. The primary experiment involved training on suspected PD versus non-PD and testing on self-reported PD versus non-PD. A secondary analysis evaluated the reverse direction by training on participants with self-reported PD and without PD and then testing on participants with suspected PD versus participants without PD. Additionally, a cross-validation analysis was conducted using participants with self-reported PD versus those without PD with 5-fold cross-validation to establish baseline performance under well-defined diagnostic labels. The best-performing models included a multimodal Vision Transformer in the primary experiment (F1: mean 0.7619, SD 0.0535), a multimodal ResNet-50 in the secondary analysis (F1: mean 0.9353, SD 0.0334), and an image-based DenseNet-201 in the cross-validation analysis (F1: mean 0.9027, SD 0.0332). Training on patients with suspected PD yielded meaningful performance in predicting self-reported PD, supporting the feasibility of using lower-specificity labels for model development. This pilot feasibility study suggests that remotely collected mouse-tracing data can support PD screening models under data labeling conditions of low diagnostic specificity: models trained on suspected PD from a community sample may learn signals that can transfer to predicting actual PD. Future work may consider pretraining using weaker labels and then fine-tuning on stronger clinical labels.",

Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.",
"42363684": "ID: 42363684\nTitle: FMRP-Mediated Proteasome Regulation: A Novel Mechanism in ALS Pathology.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a rare and fatal neurodegenerative disease characterized by the hallmark cytoplasmic accumulation and aggregation of TAR DNA binding protein 43 (TDP-43), which impairs proteasome activity through its interaction with Tankyrase (TNKS). Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31\u2009kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system. We have demonstrated for the first time that FMRP can act as a disease modifier for ALS. ALS patients with high FMRP expression in the brain and spinal cord may exhibit more severe protein aggregation due to proteasome dysfunction.",

Short RNA oligonucleotides can reverse this behavior, yet the structural determinants that govern RNA activity remain poorly defined. Here, we identify RNA G-quadruplexes (rG4s) as tunable structural motifs that potently modulate FUS LLPS. rG4 activity depends on its concentration and is modulated by rG4 length and stability: increasing repeat number switches rG4s from inhibitor to nucleator of FUS assembly, whereas chemical modifications that stabilize rG4 enhance inhibitory function and render these activities resilient to ionic perturbation. Although short rG4s interact with both soluble and condensed FUS, they preferentially engage the soluble pool, likely shifting the equilibrium toward dispersion. Leveraging these mechanistic insights, we developed a bioinformatic pipeline that uncovered more rG4 inhibitors that robustly reverse FUS LLPS and aggregation. Our findings establish rG4s as chemically programmable regulators of protein phase behavior and provide a blueprint for engineering RNA-based therapeutics that dissolve pathogenic FUS assemblies. More broadly, this work directly links RNA secondary structure to distinct functional outcomes in phase behavior, establishing a structure-function paradigm for RNA control of condensates, demonstrating implications in both fundamental biology and therapeutic development.",

People who use drugs (PWUD) in CBDs navigate intersecting risks related to criminalization, stigma, hostile architecture, urban redevelopment, and limited access to essential services-factors that compound health disparities and increase morbidity and mortality. Yet CBDs also function as sites of informal social networks, mutual aid, and adaptive survival strategies that, while precarious, constitute critical resources for daily safety and belonging. This focused ethnographic study, conducted in Edmonton's CBD between July 2022 and September 2023, draws on 25 semi-structured interviews and over 170\u00a0h of embedded field immersion to investigate how intersecting environmental forces shape the daily lives of PWUD. Using Collins et al.'s (2019) intersectional risk environment framework and Duff's (2009) enabling environment concept, we analyzed how physical, social, economic, and policy environments-operating across micro and macro levels-produce differential harms and, simultaneously, generate precarious yet meaningful sites of connection, resourcefulness, and collective care. Findings reveal how displacement, over-policing, and gentrification-driven spatial change coexist with participants' place-based belonging, moral economies of reciprocity, and culturally grounded survival knowledge. We argue that effective interventions must account for this co-production of risk and enabling conditions and that urban governance must center the voices of those most structurally affected.",
"42365390": "ID: 42365390\nTitle: Lysophagy protects against ANXA11 amyloid fibril toxicity and propagation in FTLD.\nAbstract: Accumulation of Annexin A11 (ANXA11) aggregates is a distinct pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.",

Anticipating the geographic distribution and clinical needs of this population is essential for optimizing care delivery and ensuring readiness as new therapies become available. We estimate the number of individuals in the United States carrying ALS risk variants and project the clinical engagement required to support this population. This is especially timely because ALS clinics are already grappling with rising numbers of patients with symptomatic ALS and deep funding cuts. We developed a population model to estimate the number of symptomatic individuals with gene-positive ALS and asymptomatic gene carriers across US states over the next decade (year 1: 2026). State-level ALS prevalence and incidence were calculated using 2 approaches: (1) race-adjusted ALS rates from the Atlanta metropolitan study applied to 2023 Census demographics and (2) observed state-level ALS case counts from the National ALS Registry (2011-2018). Gene-positive cases were estimated using published frequencies of SOD1, C9orf72, FUS, and TARDBP pathogenic variants. At-risk relatives were modeled assuming autosomal-dominant inheritance with \u223c5 first-degree and \u223c7 second-degree living relatives per proband, and broad uptake of cascade genetic testing. Surveillance needs were modeled as 1 annual visit per asymptomatic carrier, which was normalized by the number of ALS centers per state. In year 1 (2026), the model estimated 2,704 symptomatic gene-positive ALS carriers. With an average of 4.25 carrier relatives per proband, 10,944 asymptomatic carriers were projected nationwide. Most states required <50 additional visits per clinic annually, with 12 states in the 50-99 range and none exceeding 100. By year 10 (2035), the model projected 7,474 symptomatic and 26,111 asymptomatic carriers. State-level demand shifted substantially: only 6 states remained below 50 visits per clinic annually; 22 reached 50-99; 18 reached 100-199; and 3 exceeded 200. Gene-targeted testing is projected to substantially increase ALS clinic visits among asymptomatic gene carriers. While current infrastructure may accommodate the initial rise, within a decade, most states will require significant expansion. Anticipating and planning for this growth now is essential to ensure seamless integration of gene-positive individuals into ALS care.",

Despite significant advances in molecular and neuroimaging biomarkers, the initial site of pathology and the causal contribution of UMN dysfunction to disease progression remain undetermined. Accumulating neurophysiological evidence points to cortical hyperexcitability as an early and potentially upstream mechanism, raising the possibility that UMN pathology drives LMN degeneration through an anterograde dying-forward process. In this review, we synthesize findings from noninvasive brain stimulation (NIBS) studies, with particular emphasis on transcranial magnetic stimulation (TMS)-based neurophysiological markers of UMN dysfunction. We review evidence from TMS-electromyography (TMS-EMG) and TMS-electroencephalography (TMS-EEG) paradigms demonstrating cortical disinhibition and excitatory-inhibitory imbalance in ALS, consistent with impaired GABAergic interneuronal dysfunction and supportive of a cortical onset hypothesis. Finally, we propose integrating transcranial focused ultrasound (tFUS) with TMS as a novel experimental and translational framework to directly examine and modulate cortical hyperexcitability and test the causal role of UMN dysfunction in ALS. The combination of targeted neuromodulation with sensitive neurophysiological readouts in controlled experimental designs offers a promising avenue to advance mechanistic insight, refine biomarkers, and inform mechanism-based therapeutic strategies. Together, these approaches position noninvasive neurophysiology as a powerful tool for elucidating UMN dysfunction in ALS.",

Evidence regarding AF ablation efficacy and safety in CA patients remains limited. The aim of our study is to evaluate baseline characteristics, clinical course and outcomes of AF ablation in a series of patients with transthyretin (ATTR) or light-chain (AL) CA from a multicentre international registry. Patients with CA who underwent AF ablation were included. Co-primary endpoints were: (i) atrial arrhythmia (AA) recurrence; (ii) a composite endpoint of all-cause mortality and heart failure hospitalization (HFH). 109 patients (mean age 72.4 \u00b1 7.4 years, females 17.4%, persistent AF 64.2%, ATTR 78%, AL 22%) were included. Radiofrequency, cryo-balloon and pulsed-field ablation were performed in 67%, 15% and 18% of patients, respectively; 49.5% received pulmonary vein isolation plus additional ablations. Low voltage zones were documented in 34 out of 44 patients undergoing electro-anatomical mapping (77.3%). During a median follow-up of 22.7 months, 63 patients (58.3%) experienced AA recurrence (32.4% persistent AF recurrence), with no significant differences between CA subtypes (ATTR 59.5% vs. AL 54.2%, log-rank P = 0.55). The composite endpoint of HFH and all-cause death occurred in 27 patients (25%). Recurrence of persistent AF was associated with three-fold higher risk (OR 2.9, P = 0.02) of the composite endpoint. CA patients undergoing AF ablation present high prevalence of persistent AF. Freedom from AA after AF ablation is achieved in 42% of patients after a two-year follow-up. Patients with persistent AF recurrence have a three-fold higher risk of HFH and death.",

These diseases result from an interaction between the environment and genetically predisposed individuals. This review examines the evidence available in the literature underlying this multifaceted interaction, focusing on various chemical substances such as metals, fertilizers, and herbicides, as well as toxic agents of microbiological origin, including cyanobacteria and their neurotoxins. In addition, the pathways through which toxic substances can enter the human body are discussed, such as air and water, which may lead to absorption through the lungs, the gastrointestinal tract, the skin, and mucosae. The routes by which neurotoxic substances gain access to the human body may help explain the increased risk of developing neurodegenerative diseases observed in sports played on soil and grass surfaces, such as soccer, American football, and golf.",

The D50 disease progression model is a framework to comprehensively dissect biomarker-signals towards their relevance regarding disease accumulation/phase (rD50), or disease aggressiveness (D50). Based on previous findings using 1.5-Tesla Magnetic-Resonance-Imaging (MRI), this study hypothesized that high-resolution MRI markers of Grey-Matter (GM) structural integrity would enable quantification of disease accumulation, independent of aggressiveness. A separate cohort of 75 patients with ALS and 73 Healthy Controls (HC) underwent T1-weighted 3-Tesla MRI. Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p\u2009<\u20090.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p\u2009<\u20090.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p\u2009<\u20090.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results. These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness. This principle was validated across different scanners and field strengths, supporting its application for objective and non-invasive staging of patients with ALS, whereby true longitudinal studies are necessary.",

Population level mortality patterns in the United States in the previous decades remain insufficiently described. We quantified national mortality trends associated with hereditary ataxias and described stratified trends by sex, race, census region, and urbanization. We analyzed U.S. Multiple Cause of Death data from CDC WONDER for 2000 to 2020. Decedents were identified using ICD-10 code G11 for hereditary ataxias. Age-adjusted mortality rates (AAMRs) per 100,000 were computed using the 2000 U.S. standard population, with 95% confidence intervals. Temporal trends were evaluated using joinpoint regression to estimate annual percent change (APC). Forecasts through 2050 were generated using ARIMA, with sensitivity analysis using linear regression. National AAMR increased significantly from 2000 to 2020. Rising rates were observed in both sexes, with consistently higher mortality among males. The largest relative increases occurred among Black or African American individuals and in the West census region. Trends were directionally consistent across urbanization categories, and the forecast analyses also indicated increasing overall mortality. Sensitivity analyses produced qualitatively similar patterns, with wider uncertainty within strata. Mortality associated with hereditary ataxias increased in the United States between 2000 and 2020, highlighting growing clinical and public health needs related to cerebellar disease. Improved phenotyping and coding, earlier diagnosis, and registry-linked surveillance may refine estimates and support service planning.",

Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies.",

The mechanisms by which luminal changes relay to the central nervous system (CNS), where motor neurons reside, have yet to be completely defined. In this narrative review, we first present evidence from ALS patient cohorts and preclinical models alongside mechanistic studies of infection, dysbiosis, and related neurodegenerative diseases to discuss how the microbiota and its metabolites may affect the ENS and CNS in ALS. Next, we propose a plausible mechanism of ALS pathogenesis through the gut-microbiome-brain axis. We further offer a summary of clinical trials that have studied the impacts of the microbiota on human ALS. Finally, we discuss future directions for studies of microbiota-ENS-CNS interactions in ALS. Better understanding of the dynamic interactions among the microbiota, microbial metabolites, neuroactive metabolites, and inflammation through the ENS/CNS in ALS will provide innovative insights into ALS prevention and treatment.",

Distal Motor Latency (DML) is a simple electrophysiological measure that is always done in a primary setting. It can be used as an excellent prognostic marker for ALS so that we can know ALS better and formulate precise management plans. This longitudinal study was conducted in the Neurology Department of Bangladesh Medical University (BMU), Dhaka, Bangladesh from April 2022 to October 2023. In this study a total of 34 subjects, 17 ALS patients with normal DML and 17 ALS patients with prolonged DML, were enrolled. Severity was assessed by the ALS functional rating scale-revised (ALSFRS-R). The study's endpoints were determined as death during this 6-month follow-up or reaching an advanced stage (ALSFRS-R <20). Then, an electrophysiological test was used to measure DML in all four commonly tested nerves. ALSFRS-R was significantly reduced (p<0.025) at 6 months in ALS patients with prolonged DML than normal DML. It was found that having a higher odd (p<0.012, OR=20.718), prolonged DML had a significant impact on the outcome of ALS patients than that of normal DML. In multivariate analysis, lower ALSFRS-R at diagnosis (B= -0.124, p<0.001, HR=0.883) and prolonged DML (B=1.412, p<0.031, HR=4.104) were associated with poor outcomes. ALS patients with prolonged DML also had a poorer prognosis than patients with normal DML (log-rank test, p<0.045). In this study, patients with prolonged DML had a significant functional decline, rapid disease progression and poor prognosis than patients with normal DML. So, prolonged DML can be used as a robust prognostic marker for patients with ALS.",

A total of 119 oral swabs were collected from cat owners and streaked directly on Sabouraud's dextrose and chrome agars. Confirmation was performed by testing the isolates using the Vitek 2 compact system and conventional polymerase chain reaction (PCR) using primers specific to the ITS4 and ITS5 regions. ALS and ECE1 genes were detected using conventional PCR. The total number of Candida spp. isolated from the oral cavity of cat owners was 10/119 (8.40%). Correlations were reported between the isolation of Candida from the oral cavity and age group; use of oral antibiotic drops; diabetes mellitus; oral lesions; and vitamin D3 deficiency (p value < 0.001). No significant correlation was reported between sex, season, smoking habit, denture wearing, steroid inhalation, immune suppression, and Candida isolation from the oral cavity of cat owners. ASL1 and ECE1 were detected in 100% of C. albicans isolated from the oral cavity of cat owners. This study reveals a low prevalence but high pathogenic potential of oral C. albicans in domestic cat owners, as evidenced by the universal presence of major virulence genes (ALS1, ECE1). Older age, antibiotic drops, Diabetes miletus, oral lesions, and vitamin D3 deficiency were associated with the risk of colonization. The commonly suspected risk factors showed no association. The universal presence of ALS1 and ECE1 highlights the pathogenic threat posed by these yeasts.",

A critical perspective on drug safety and disease vulnerability.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with limited treatment options and diverse symptoms necessitating active management. Anticholinergic medications are frequently used in ALS care, particularly for sialorrhea and mood disturbances. Their cumulative effects, termed anticholinergic burden, may pose underrecognized risks in this neurologically vulnerable population. This review highlights a plausible safety signal and outlines priorities for future research. This narrative review synthesizes evidence from non-ALS populations reporting associations between higher anticholinergic burden and cognitive decline, respiratory complications, functional deterioration, and mortality. Evidence was identified through targeted PubMed/MEDLINE and Embase searches with reference chaining, emphasizing recent and seminal studies. Mechanistic overlap with ALS pathophysiology, including neuromuscular junction disruption, impaired cholinergic signaling, and neuroinflammation, supports biological plausibility for harm. Current ALS guidelines do not address cumulative anticholinergic exposure, leaving clinicians without a framework for evaluating risk or deprescribing. This article proposes a testable hypothesis that anticholinergic burden may represent a clinically relevant yet unmeasured risk factor in ALS. Emerging pharmacoepidemiologic methods and validated burden tools offer approaches to quantify exposure and evaluate relationships with ALS outcomes, supporting safer symptomatic management. Prioritizing longitudinal studies and integrating burden assessment into multidisciplinary care may help clarify risk.",

Temporal trends were modeled using Joinpoint regression, and 10-year forecasts were obtained using autoregressive integrated moving average models. Subgroup analyses were performed by sex, race/ethnicity, census region, urbanization, and place of death.ResultsWe identified 199,606 Alzheimer's disease-cardiovascular disease-related deaths. Overall, age-adjusted mortality rates peaked at 24.8 in 2002, reduced to 14.2 in 2013, and then rose to 18.7 in 2020 before dropping to 16.6 in 2023. Women exhibited higher age-adjusted mortality rates than men (20.1 vs. 16.0). Individuals of White and Black ethnicity bore the greatest burden, and the South and West recorded the highest regional age-adjusted mortality rates. These rates were consistently higher in non-metropolitan areas than in metropolitan areas. Exploratory projections estimate an overall age-adjusted mortality rate of 16.6 by 2033, with persistently higher rates in women, non-Hispanic Black populations, and among those residing in the West and non-metropolitan areas.ConclusionsDespite substantial decline since the early 2000s, Alzheimer's disease-cardiovascular disease mortality remains high and unevenly distributed. Exploratory projections suggest that the burden will remain substantial, underscoring the need for targeted prevention, vascular risk reduction, and equity-focused dementia care.",

Although mineral dyshomeostasis has been implicated in the pathogenesis of AD, its role in CCD remains largely unexplored. This retrospective study aimed to investigate regional brain mineral concentrations in 24 dogs with CCD and 15 dogs exhibiting successful cognitive aging (non-CCD). CCD diagnosis was based on the results of caregiver questionnaires, physical examination and laboratory analyses after ruling out any other intracranial disease. Four cortical regions with high \u03b2-amyloid pathology (prefrontal, parietal, temporal and occipital cortex) and one generally unaffected region (cerebellum) were analysed to determine the concentrations of 20 minerals by using plasma-based optical techniques and mass spectrometry. Compared to non-CCD dogs, CCD dogs had significantly lower concentrations of Ca, Fe, Mg, Mn and Zn, and higher levels of Cd, Mo, Ni and Pb in specific brain regions. The greatest number of significant differences were observed in the prefrontal cortex, the earliest and most consistently affected region in CCD, whereas the cerebellum remained largely unchanged. Principal component analysis distinguished CCD from non-CCD dogs and, within the CCD group, showed clustering of the cerebellum separately from cortical regions. The regional specificity of these alterations and their ability to distinguish CCD from non-CCD dogs support a link between disrupted mineral homoeostasis and CCD. Notably, lower concentrations affected essential trace elements involved in antioxidant defence, neuronal signalling and neurotransmission, raising the possibility of functional implications that warrants further investigation.",

An increasing proportion of women in Romania experiencing infertility are resorting to in vitro fertilization (IVF) to achieve pregnancy. Our study included 47 women who completed an IVF cycle at the 1st Obstetrics and Gynecology Clinic (Cluj-Napoca), between April - October 2019, and July - December 2022. All participants completed a questionnaire. We collected data from the participant medical records on antral follicle count, levels of hormones, response to ovarian stimulation, number of retrieved oocytes, thickness of the endometrial mucosa, and IVF endpoints (fertilized oocytes, number and quality of embryos, pregnancy, live births). Urine, blood, ovarian follicular fluid, and endometrial flushing fluid specimens were collected at the time of oocyte retrieval, for metal and genetic analysis. Lead (Pb), arsenic (As) and cadmium (Cd) levels were measured in biological samples collected from our study participants using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) technique. In approximately 19% of the analyzed samples, the total urinary As exceeded the reference value of 15 \u00b5g/L. Also, in 15% of the samples, urinary Cd exceeded the reference value of 2 \u00b5g/L, while the blood Pb levels were below 10 \u00b5g/dl. Our study results indicated no significant differences as regards the IVF outcomes in relation with low-level As, Cd and Pb exposure, whereas higher tobacco smoke exposure, assessed via urinary cotinine, was linked to a lower fertilized oocytes and blastocysts number.",

A total of 2,215 thyroid surgeries and 194 autopsies were reviewed, identifying 17 and 1 case of NRLN, respectively. Data regarding nerve anatomy, associated vascular anomalies, and patient medical history were collected and analyzed. Neck ultrasound examinations were subsequently performed on the 17 living patients, 5 months to 19 years post-surgery, by three radiologists specializing in head and neck soft-tissue imaging. Two radiologists were blinded to the specific nerve anatomy, while one was unblinded. Vascular anomalies of the aortic arch were described only by the unblinded radiologist. Among the 17 NRLN cases, three (16.7%) exhibited normal vascular anatomy. According to Toniato et al.'s classification, one case each was categorized as 2a, 2b, and one case involved a coexisting right NRLN and right RLN. No definitive recurrent paresis was observed, with only one patient experiencing transient palsy lasting 5 weeks. Histological evaluation revealed no structural differences between NRLN and RLN variants, although their epineurium and adventitia were notably thinner than those of the vagal nerve. Achieving blood-free conditions for meticulous dissection and preserving sympathetic nerve branches are essential for optimal functional outcomes in thyroid surgeries involving NRLNs.",

While promising as biomarkers, their longitudinal trajectories across multiple biofluids remain poorly defined. To quantify polyQ ATXN3 levels in cerebrospinal fluid (CSF), plasma, and urine within a comprehensive cohort, utilizing serial measurements to map protein dynamics. We employed a validated immunoassay to quantify polyQ ATXN3 in 97 symptomatic and 13 presymptomatic SCA3 patients, correlating levels with clinical features, ancestry, disease status, and longitudinal progression. Asian participants exhibited lower plasma but elevated urinary polyQ ATXN3 levels relative to other ancestries. While CSF levels were higher in symptomatic patients at baseline, they showed a significant longitudinal decline. PolyQ ATXN3 is a viable multi-biofluid biomarker. Declining CSF levels likely reflect neurodegeneration, supporting its role in tracking progression and emphasizing the need for ancestry-based adjustment in trials. \u00a9 2026 International Parkinson and Movement Disorder Society.",

The advent of human induced pluripotent stem cell (hiPSC) technology has enabled the generation of human-specific brain cell types in\u00a0vitro. Here, we provide an overview of the three-dimensional (3D) hiPSC-derived neural organoid platforms used to model cortical structures and to study cortical ALS-associated phenotypes. We review which pathological hallmarks have been recapitulated in these organoids and discuss disease phenotypes reported to date. Further, we comprehensively cover different neural organoid models and experimental strategies, including patient-derived hiPSC models and exogenous pathology induction, while addressing current technical challenges.

"42383305": "ID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.",

The gut microbiota influences the immune system, metabolism, and nerve cells through the production of neurotransmitters and microbial metabolites that can cross the blood-brain barrier (BBB). The interplay between neuroinflammation and altered oral and gut microbiota is a bidirectional complex path modulated by inflammatory mediators. Recent studies suggest a potential role for Toll-like receptor (TLR) signaling pathways in the induction of neuroinflammation via the oral-gut-brain axis. As neuroinflammation is one of the key elements in the pathophysiology of neurodegenerative and neuropsychiatric disorders, this review was conducted to reflect on the pathophysiological pathways and clinical evidence on the role of TLR and inflammasome signaling pathways via oral-gut-brain axis in neurodegenerative diseases such as cognitive impairment, Alzheimer's disease, Multiple sclerosis, Parkinson's disease, Huntington's disease, and Amyotrophic lateral sclerosis, and psychiatric disorders such as major depressive disorder, anxiety disorders, schizophrenia, bipolar disorders, and Autism spectrum disorders.

While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (<\u200930 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR\u2009=\u20093.5\u2009\u00d7\u200910-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.",

Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.",

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9\u00b711 million (95% uncertainty interval 8\u00b704-10\u00b73) incident cases of all-form TB, 1\u00b722 million (0\u00b798-1\u00b749) deaths, and 54\u00b76 million (43\u00b78-65\u00b75) DALYs globally. HIV-related TB comprised 781\u2008000 (690\u2008000-879\u2008000) incident cases and 210\u2008000 (142\u2008000-279\u2008000) deaths, contributing 11\u00b70 million (7\u00b756-14\u00b73) DALYs. MDR-TB accounted for 466\u2008000 (198\u2008000-1\u2008080\u2008000) incident cases, 102\u2008000 (31\u2008700-238\u2008000) deaths, and 3\u00b796 million (1\u00b731-9\u00b701) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19\u00b72% (17\u00b78-20\u00b75) and deaths declined by 22\u00b76% (4\u00b77-35\u00b77); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768\u2008000 (592\u2008000-970\u2008000) and DALYs to 34\u00b79 million (27\u00b78-43\u00b78) in 2023; MDR-TB deaths would decrease to 77\u2008200 (23\u2008400-183\u2008000) and DALYs to 3\u00b712 million (1\u00b703-7\u00b729). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

The SQSTM1 protein regulates the degradation of polyubiquitinated proteins and autophagosome formation through its interaction with microtubule-associated protein light chain 3 (MAP1LC3/LC3). However, the molecular mechanisms by which SQSTM1-LC3 binding regulates the autophagy-endolysosomal system (APELS) remain unclear. To elucidate the spatiotemporal role of SQSTM1, we transiently expressed wild-type SQSTM1 or missense mutants carrying mutations in the LC3-interacting region (LIR), fused with the photoconvertible fluorescent protein Dendra2. Live-cell fluorescence imaging and co-localization analyses with markers of the APELS were then performed. Particle analysis of photoconverted or non-photoconverted SQSTM1-positive structures in live cells revealed that the pathogenic L341V variant formed larger structures than the wild-type. Co-localization analyses further showed that both the L341V and artificial LIR3A mutants accumulated in large ubiquitin-positive structures, likely due to impaired localization to autophagosomes. These results suggest that mutations within the LIR differentially affect autophagosome formation and cargo degradation within APELS-related compartments, highlighting the importance of SQSTM1 structural integrity in ALS/FTD pathogenesis.",

Our team developed a digital depression intervention (VMood; smartphone app) in Vietnam. VMood is adapted from an evidence-based in-person intervention (SSM) developed in Canada and uses cognitive behaviour therapy (CBT) principles with remote coaching by non-specialist providers. Fidelity-adaptation is a major tension in implementation science. Fidelity is the degree an intervention is designed and delivered as intended. Conversely, adaptations are sometimes made for specific contexts. This paper aims to identify key elements of fidelity-adaptation - the degree VMood is consistent theoretically with the SSM intervention and practically with implementing digitally in the Vietnamese setting. This study uses Perez et al.'s modified version of Carroll et al.'s Implementation Fidelity Framework, focusing on Objective 1: Conceptualizing what intervention fidelity means in this specific context (across modes and cultures) and Objective 2: Conducting fidelity testing to identify key elements along the fidelity-adaptation continuum. Ethnographic data from team meetings explored essential components that must remain intact and necessary adaptations. Non-specialist providers and app users from Vietnam tested VMood. Experts familiar with CBT provided theoretical feedback. Interviews or focus groups were conducted with all participants to gain insights into the adaptive intervention. Qualitative data were analyzed using thematic content analysis. Participants agreed that VMood captures the essential theoretical components from SSM, noting certain elements of SSM (e.g., change in human contact to online) could not be replicated digitally. Participants also presented adaptation suggestions unique for the digital format to strengthen VMood's acceptability, including keeping the app simple by reducing the amount of text; incorporating more dynamic content (e.g., animations) to increase engagement; and including more culturally appropriate scenarios. Finally, key potential moderators to fidelity reported included quality of program delivery and participant responsiveness. Findings identified intervention specific elements of fidelity-adaptation and showed that VMood retained essential components of SSM while incorporating adaptations to support implementation within the Vietnamese context. With the global increase in digital health services adapted from in-person delivery, understanding how to balance fidelity with necessary adaptations is important both theoretically and practically.",

This gap has significant implications for treatment efficiency, safety, health economics, and sustainable healthcare. A 2000 to 2025 (July) PubMed search identified 3,488 articles, but only 7 articles met the criteria for providing a method to determine the muscles involved in AJP due to muscle spasticity. Of these, just 2 have proposed how to measure each muscle contribution and only 1 focused on identifying the muscle actually responsible for the observed AJP. There are many strategies for determining the muscles involved in spasticity-related AJP, but they are primarily based on inference. They draw on clinical skills, which incorporate descriptive and functional anatomy, knowledge of different muscle and joint structures, simple rules of biomechanics, determination of the exact phase of the movement involved, consideration of compensatory AJP in these motor control deficient patterns, and, of course, the patient's goals. Achieving the authors' proposed objective would enable the standardization of clinical practices, confirm the effectiveness of treatments for spasticity, particularly botulinum toxin, and ensure that the correct dose is injected in the right muscle.",

In the randomised, double-blind phase III MycarinG study, one 6-week rozanolixizumab cycle significantly improved MG-specific outcomes versus placebo and was generally well tolerated in patients with generalised MG (gMG). To assess the efficacy and safety of cyclic rozanolixizumab treatment. A pooled analysis of the MycarinG, MG0004 and MG0007 studies. Following MycarinG, eligible patients could enrol in the open-label extension studies MG0004 or MG0007 to receive rozanolixizumab 7 or 10\u2009mg/kg. In MG0004, patients received chronic weekly treatment for \u2a7d52\u2009weeks. In MG0007, after an initial 6-week treatment cycle, subsequent cycles were based on symptom worsening (investigator's discretion). Final efficacy data were pooled across MycarinG, MG0004 (first 6\u2009weeks) and MG0007 for patients receiving \u2a7e2 symptom-driven cycles. Efficacy endpoints included change from baseline (CFB) in MG Activities of Daily Living (MG-ADL), MG Composite (MGC) and Quantitative MG (QMG) scores. Safety outcomes were assessed in patients who received \u2a7e1 cycle with a \u2a7d8-week follow-up period across MycarinG and MG0007. Overall, 188 patients received \u2a7e1 cycle and 129 received \u2a7e2 symptom-driven cycles. Across Cycles 1-13, mean (standard deviation) CFB to Day 43 in MG-ADL score ranged from -3.2 (3.3 (n\u2009=\u2009113; Cycle 3)) to -6.0 (3.9 (n\u2009=\u200924; Cycle 12)). Consistent improvements in MGC and QMG scores were also observed across repeated cycles. Treatment-emergent adverse events (TEAEs) were experienced by 175/188 (93.1%) patients; most mild or moderate. Incidence remained stable with repeated cyclic treatment among patients who remained in the study at each cycle. The most common TEAE was headache (n\u2009=\u200994/188 (50.0%)). Repeated rozanolixizumab treatment cycles demonstrated consistent, clinically meaningful improvements in MG-specific outcomes as early as 1\u2009week after the first infusion. Rozanolixizumab was generally well tolerated with an acceptable safety profile, supporting its long-term use as a treatment option for adults with gMG.

In the MycarinG study, treatment with rozanolixizumab once a week for 6 weeks was better at improving gMG symptoms than placebo in adults with gMG. After MycarinG, patients could enter the extension studies MG0004 and MG0007. These studies assessed the side effects of long-term rozanolixizumab treatment and measured patients\u2019 symptoms to see whether rozanolixizumab remained effective. In MG0004, patients received rozanolixizumab once a week for up to 52 weeks. In MG0007, patients received rozanolixizumab once a week for 6\u2009weeks, termed a treatment cycle. After the first treatment cycle, patients only received more cycles if their symptoms worsened. We looked at data from patients who received repeated rozanolixizumab treatment cycles across MycarinG, MG0004 (first 6 weeks only) and MG0007. Treatment side effects and gMG symptoms were assessed. Overall, 129 patients received two or more rozanolixizumab cycles due to worsening symptoms. We saw consistent improvements in gMG symptoms across multiple measures; improvements were maintained over repeated treatment cycles. Altogether, we assessed 188 patients for side effects; 175 (93.1%) reported a side effect, most of which were mild or moderate in severity. The most common side effect was headache. The number of reported side effects and how bad they were did not change much across treatment cycles among patients who stayed in the study at each cycle. In the first year of treatment, patients had an average of four treatment cycles. Based on this, rozanolixizumab treatment would be expected to follow a repeated pattern of 6\u2009weeks on treatment and 6\u20138\u2009weeks off in the first year. Together, these data suggest that repeated rozanolixizumab cycles can be used for long-term treatment in patients with gMG.",

Randomised prospective multicentre simulation study with a parallel-group comparison of four predefined team sizes. Three accredited EMS training centres in North Rhine-Westphalia, Germany. 210 ALS-trained paramedic students allocated to 59 teams of two to five members. Teams managed a standardised adult ALS scenario (persistent ventricular fibrillation) requiring five invasive procedures: manual defibrillation, supraglottic airway insertion, intravenous access, preparation of amiodarone (300\u00a0mg), and preparation of epinephrine (1\u00a0mg). The primary endpoint was total scenario time from start to completion of the final procedure. Secondary endpoints were start and completion times for each intervention. Mean total times (mm:ss) decreased progressively with team size: two-person 6:33\u00a0\u00b1\u00a00:33\u00a0min, three-person 4:13\u00a0\u00b1\u00a00:40\u00a0min, four-person 2:54\u00a0\u00b1\u00a00:24\u00a0min, and five-person 2:14\u00a0\u00b1\u00a00:19\u00a0min (ANOVA, p\u00a0<\u00a00.001). All pairwise differences were statistically significant (Bonferroni-corrected p adj\u00a0<\u00a00.01). Earlier initiation of intravenous access and drug preparation accounted for most time savings. All teams completed every task successfully. Larger EMS teams performed time-critical ALS procedures significantly faster, with optimal efficiency observed in four- to five-member crews. These findings highlight the operational importance of team composition for prehospital resuscitation performance and may inform staffing policies and simulation-based training.",

We conducted this scoping review following the Arksey and O'Malley framework and Levac et al's methodological recommendations, reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extensions for Scoping Reviews (PRISMA-ScR). MEDLINE (Ovid), Embase (Elsevier), CINAHL (EBSCO) and Web of Science were searched from database inception to 8 November 2024. The search was updated on 18 May 2026. This was supplemented by forward and backward citation tracking of included peer-reviewed articles and targeted hand searching of Dutch grey literature in Medisch Contact , a leading Dutch professional journal for the medical profession, focusing on clinical practice, medical policy and professional issues. English-language or Dutch-language peer-reviewed publications and well-argued opinion pieces on healthcare workers' access to care (COVID-19 and beyond) in hospital or transferable settings were included. Sources focused on mental health or health promotion, financial aspects, personal protective equipment, patient access or healthcare worker utilisation, as well as non-English/Dutch sources, webpages and papers without full text, were excluded. ASReview was used for title and abstract screening following the SAFE procedure and full-text screening was conducted with team consensus. 27 publications were included from 36\u2009685 identified records. The literature was predominantly qualitative in nature and COVID-19-focused, yielding four themes (ethical considerations, multilevel challenges, target groups and strategies and outcomes). It also highlighted limited evidence on evaluated supported-access interventions and workforce outcomes beyond crises. Although supported access to medical care for hospital employees appears a promising multilevel, system-embedded strategy to reduce sickness absenteeism and promote sustainable employability in general, the evidence to substantiate and justify such strategies beyond acute crises is limited. Moreover, current literature lacks clear conceptualisation, operationalisation as well as robust implementation and evaluation frameworks. Addressing these gaps is a priority for future research to scientifically scaffold policies and frameworks to sustain a healthy and stable future hospital workforce.",

All known ALS-linked SPTLC1 mutations cluster within exon 2, and a specific variant, c.58G>T, results in exon 2 skipping. However, it is unclear how the exon 2 deletion affects SPTLC1 function in vivo and contributes to ALS pathogenesis. Leveraging the high genomic sequence similarity between mouse and human SPTLC1, we created a novel knock-in mouse model with a CRISPR/Cas9-mediated deletion of exon 2 in the endogenous murine Sptlc1 locus. Although heterozygous mice did not develop motor defects or ALS-like neuropathology, homozygous mutants died prematurely. These findings provide valuable insights into SPTLC1 exon 2 biology and serve as a useful resource for future mechanistic studies.",

Whether this divergence is driven by demographic change or epidemiological shifts remains unclear, particularly in China. Using data from the Global Burden of Disease Study 2021, we analysed trends in MND burden in China from 1990 to 2021. Decomposition analysis was applied to quantify the contributions of population ageing, population growth, and changes in age-specific rates. Age-specific incidence patterns were compared with global estimates, and key findings were validated against recent Chinese epidemiological studies. Despite declining age-standardised prevalence and DALY rates, the absolute number of cases and DALYs increased substantially. Population ageing accounted for 46.0% of the increase in DALYs, followed by population growth (35.0%) and changes in age-specific rates (19.0%). Age-specific incidence rates in China were consistently lower than global estimates. External validation demonstrated high consistency with national epidemiological studies. The increasing burden of MND in China is primarily driven by demographic ageing rather than increasing disease risk. Declining age-standardised rates may mask growing healthcare demands in rapidly ageing populations.",
"42393765": "ID: 42393765\nTitle: Phenotype-specific muscle proteomic profiling in titinopathies.\nAbstract: Titinopathies are complex neuromuscular disorders with multiple phenotypes. The gene's size, comprising 364 exons, as well as the protein's size of 3.8 MDa and its extensive network of protein interactors, are key factors underlying this complexity. Various phenotypes characterize titinopathies, and this study focuses on two of them: arthrogryposis and myofibrillar myopathies. The protein deregulations associated with these two phenotypes remain unknown or have been minimally explored; however, understanding these consequences is essential for better characterizing the pathophysiological aspects of these titinopathies.The objective was to analyze protein deregulations in two cohorts of French patients with titinopathies exhibiting the arthrogryposis and myofibrillar myopathy phenotypes, and to compare them with control individuals. Protein extracts were obtained from muscle biopsies of patients, and changes in protein levels within these two groups were analyzed by mass spectrometry. The results indicate specific deregulations in each group. The networks analyzed revealed deregulation of proteins involved in fibrosis mechanisms or in the actomyosin complex for the arthrogryposis phenotype. Regulation of the muscle contraction system through deregulation of proteins involved in the cytoskeleton is impacted in patients with myofibrillar myopathy. The proteins that are quantitatively abnormal in these two groups also provide insights into the major signaling networks disrupted in titinopathies. These findings will contribute to a more precise characterization of titinopathies, enabling the identification of phenotype-specific biomarkers and potentially guiding the search for targeted therapies for these neuromuscular disorders.",
"42393897": "ID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-\u03b2 signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.",

The study shows that overactive bladder, maximal voided volume, and 24-h urine volume are significant predictors of NP and that both the nocturnal polyuria index and the prevalence of NP rise with age. Although these results significantly advance our knowledge of age-related urinary dysfunction, a number of methodological issues need to be addressed. The reported relationships may have been impacted by the retrospective design, reliance on self-reported voiding diaries, and lack of information on renal function, sleep problems, hydration status, and diuretic use. Furthermore, using a single diagnostic criteria for NP across all age groups might not accurately represent aging-related physiological changes. To better diagnose and treat nocturnal polyuria in older persons, future prospective studies that take these factors into account and assess age-specific diagnostic criteria are required.",
"42394935": "ID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.",

However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3\u00a0Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments.",

Improved biomarkers are imperative to improve patient care and therapeutic development. Here, we employed 35-plex isobaric tandem mass tag labeling based on isobutyl-proline reporter group (TMTpro) to perform unbiased proteomic analysis of cerebrospinal fluid (CSF) and plasma from control (n= 28, n= 31) and sporadic ALS (sALS) (n= 39, n= 41), from the Target ALS Global Natural History Study (TALS GNHS). We identified 2,875 proteins in CSF and 1,118 proteins in plasma and identified known and novel differentially expressed proteins (DEPs) between controls and sALS, some of which were orthogonally validated using immunoassay. Comparison of TMTpro-MS and Olink proximity extension assay proteomics revealed common and non-overlapping differentially expressed proteins illustrating strengths unique to each platform. This initial cross-sectional proteomic study of biofluids from the TALS GNHS, with unrestricted availability of study results to the research community, highlights the potential of this resource as a potent platform for ALS biomarker discovery.",

Early clinical experience in real-world settings confirmed the efficacy in both treatment-na\u00efve and pretreated patients but no data on longer observation periods are available yet. The aim of the study was to investigate the efficacy, treatment frequency and tolerability of aflibercept 8\u202fmg over a\u00a0period of 12\u00a0months in a\u00a0group of pretreated nAMD patients. A\u00a0retrospective study of 73\u00a0eyes with nAMD and pretreatment with anti-VEGF switched to aflibercept 8\u202fmg. Eyes were initially uploaded with 3\u00a0monthly intravitreal injections (IVI), followed by a\u00a0pro re nata (PRN) regimen. Outcome parameters included visual acuity development and central retinal thickness (CSRT) after upload and 12\u00a0months, treatment frequency in the year before and after switching to aflibercept 8\u202fmg, and the overall tolerability of the drug. Of the initial 73\u00a0eyes, 27\u00a0eyes (37.0%) were still receiving aflibercept 8\u202fmg after 12\u00a0months. In these eyes CSRT was reduced from 387.9\u202f\u00b1\u2009138.4\u202f\u00b5m initially to 305.5\u202f\u00b1\u200993.2\u202f\u00b5m after upload and 328.9\u202f\u00b1\u2009105.6\u202f\u00b5m after 12\u00a0months (p\u202f<\u20090.001). Visual acuity remained stable (p\u202f>\u20090.05). Compared to the year prior to switching, the injection frequency was reduced from 8.2\u202f\u00b1\u20092.1 to 6.9\u202f\u00b1\u20091.0 IVIs (p\u202f<\u20090.005). During the observation period, a\u00a0total of 5\u00a0eyes (6.8%) developed noninfectious intraocular inflammation (IOI), with all cases completely regressing with topical treatment. These results confirm a\u00a0good efficacy of aflibercept 8\u202fmg for the treatment of nAMD with reduced injection frequency after 12\u00a0months of treatment in a\u00a0portion of pretreated eyes that were often previously refractory to treatment. Longer observation intervals and experience with other treatment regimens are necessary to confirm this observation. HINTERGRUND: Die klinische Phase-3-Studie PULSAR zeigte, dass bei therapienaiven Patienten mit neovaskul\u00e4rer altersbedingter Makuladegeneration (nAMD) eine Behandlung mit Aflibercept 8\u202fmg in einem Gro\u00dfteil der Kohorte verl\u00e4ngerte Injektionsintervalle bei guter Vertr\u00e4glichkeit des Medikaments erm\u00f6glicht. Erste klinische Erfahrungen im Real-World-Setting konnten die Wirksamkeit sowohl bei therapienaiven als auch vorbehandelten Patienten best\u00e4tigen, allerdings liegen noch keine Daten zu l\u00e4ngeren Beobachtungszeitr\u00e4umen vor. Ziel der Studie war die Untersuchung der Therapiewirksamkeit, Injektionsfrequenz sowie Vertr\u00e4glichkeit von Aflibercept 8\u202fmg in einem Zeitraum von 12\u00a0Monaten bei einem Kollektiv vorbehandelter nAMD-Patienten. Retrospektive Analyse von 73\u00a0Augen mit nAMD und vorausgegangener Anti-VEGF-Therapie, die auf Aflibercept 8\u202fmg umgestellt wurden und nach einem Upload aus 3 monatlichen intravitrealen Injektionen (IVOMs) im Pro-re-nata(PRN)-Schema weiterbehandelt wurden. Untersucht wurden die Visusentwicklung und die zentrale Netzhautdicke (CSRT) nach Upload und nach 12\u00a0Monaten, die Injektionsh\u00e4ufigkeit im Jahr vor sowie nach Umstellung auf Aflibercept 8\u202fmg sowie die Vertr\u00e4glichkeit des Medikaments. Von initial 73\u00a0Augen wurden nach 12\u00a0Monaten noch 27\u00a0Augen (37,0\u202f%) mit Aflibercept 8\u202fmg behandelt.

While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients.",
"42398690": "ID: 42398690\nTitle: Mutant superoxide dismutase 1-catalyzed hydrogen therapy for amyotrophic lateral sclerosis achieved by intercepting oxidative stress-neuroinflammation crosstalk.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive motor neuron degeneration in the brain and spinal cord, with mutant superoxide dismutase 1 (SOD1) induced oxidative stress and neuroinflammation as key pathogenic drivers. Here, we uncover that mutant SOD1 is both a Fenton-like agent able for catalytical generation of \u00b7OH and a hydrogenation catalyst for H2 scavenging reactive oxygen species. To enhance the bioavailability of H2, we develop an orally administered Mg2Si nanosheets based feed for sustained release of high-amount H2. On an ALS model of hSOD1G93A transgenic mice, Mg2Si feed remarkably delays ALS progression, improves the motor performance of ALS mice, and extends their lifespan. Histopathologically, oral Mg2Si treatment ameliorates motor neuron degeneration, misfolded SOD1 aggregation and reactive gliosis in spinal cord, while protecting neuromuscular junctions and ameliorating muscle atrophy during disease progression. Transcriptomic analysis demonstrates the H2-mediated down-regulation of both oxidative stress and neuroinflammatory pathways in response to the suppression of NLRP3 inflammasome activation. The proposed strategy of catalyzed hydrogen therapy offers an inspiration for metalloproteases-related neurodegenerative diseases treatment. STATEMENT OF SIGNIFICANCE: Amyotrophic lateral sclerosis (ALS) is an incurable and devastating neurodegenerative disease lacking effective clinical interventions. Although hydrogen gas (H2) exhibits promising neuroprotective potential, conventional H2 therapy is severely limited by unstable and transient H2 release, failing to sustain long-term treatment requirements for chronic ALS pathogenesis. To overcome this bottleneck, we engineer oral administrable Mg2Si nanosheets that enable sustained H2 release via gastrointestinal retention, achieving stable long-term hydrogen supplementation in vivo. Mechanistically, Mg2Si-derived H2 efficiently eliminates excess free radicals triggered by toxic mutant SOD1, and further disrupts the pathological crosstalk between oxidative stress and neuroinflammation in ALS. In transgenic ALS mice, dietary Mg2Si intervention markedly ameliorates motor dysfunction and effectively delays disease progression. Collectively, this study firstly applies Mg2Si nanomaterial-based sustained hydrogen therapy for ALS treatment, establishes a novel gastrointestinal hydrogen delivery strategy, and provides an innovative and clinically translatable paradigm for the design of hydrogen delivery systems against neurodegenerative disorders.",

This retrospective observational cohort study included patients with ALS followed by a multidisciplinary palliative care team between 2018 and 2020. Patients were classified according to gastrostomy status (RIG vs no RIG). Clinical data, respiratory support, nutritional status and survival outcomes were collected from medical records. Survival was analysed from gastrostomy indication using Kaplan-Meier curves stratified by baseline non-invasive ventilation (NIV) use. Among 155 patients with ALS, RIG was indicated in 53 and performed in 45; eight patients died before the procedure. 65 patients did not undergo gastrostomy. Median survival after RIG was 14.7 months, compared with 8 months in non-RIG patients who died. Baseline NIV use was associated with longer survival. No major safety concerns were identified. RIG appears to be a safe and feasible option in advanced ALS. Multidisciplinary care with integrated palliative involvement may facilitate referral, optimise nutritional support and support shared decision-making aligned with patients' goals of care. Further prospective studies are needed to confirm benefits and identify intervention timing.",

While previous systematic reviews existed, an updated comprehensive synthesis is needed to delineate the disease burden. We searched PubMed, Embase, Scopus, Web of Science and Cochrane databases from inception to 18 February 2025, for studies reporting the incidence, prevalence or mortality of ALS in the general population. Pooled estimates with 95% CIs were calculated, and subgroup analyses were performed. Of 29\u2009110 articles initially screened, 142 were included. Global pooled incidence was 1.65 per 100\u2009000 person-years (95% CI 1.43 to 1.91), prevalence was 5.05 per 100\u2009000 population (95%\u2009CI 4.26 to 5.99) and mortality was 1.26 per 100\u2009000 person-years (95%\u2009CI 0.94 to 1.69). Both incidence rate ratio (IRR=0.74) and prevalence rate ratio (PRR=0.69) indicated significantly lower disease burden in females than in males. The burden of disease exhibited a marked age-dependent pattern, peaking at ages 70-79. Temporal trend analyses revealed a consistent increase in prevalence from 1963 to 1999\u2009onwards, while incidence peaked in 2014-2017. Geographically, incidence and prevalence were highest in Europe, North America and Oceania and lowest in Asia and South America. The disease burden was significantly higher in high-income countries compared with both upper-middle-income and lower-middle-income countries. This systematic review provides updated global ALS burden estimates, showing variations by sex, age, time and geography and underscoring the complex interplay of genetic, environmental and socioeconomic factors, with implications for health planning, resource allocation and etiological research.",

Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.",
"42399370": "ID: 42399370\nTitle: Therapeutic targeting of the conserved region within the low-complexity domain of TDP-43 is neuroprotective and extends survival in amyotrophic lateral sclerosis mice.\nAbstract: Autosomal dominant mutations in TARDBP, encoding TAR DNA-binding protein 43 (TDP-43), cause amyotrophic lateral sclerosis (ALS), and TDP-43 pathology is a hallmark of multiple aging-associated neurodegenerative diseases. Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.",
"42400303": "ID: 42400303\nTitle: Adeno-Associated Virus Gene Therapy for Spinal Muscular Atrophy Induces Hepatotoxicity via Cytokine and Macrophage Activation.\nAbstract: Hepatotoxicity is a common and significant adverse effect associated with adeno-associated virus (AAV) gene therapy; however, the underlying mechanisms remain unknown. In this study, we demonstrated innate immune activation in two patients with spinal muscular atrophy shortly after receiving AAV9 gene therapy with onasemnogene abeparvovec. Both patients developed marked hyperferritinemia accompanied by hepatotoxicity, thrombocytopenia, hypertriglyceridemia, and hypofibrinogenemia, all of which are the diagnostic criteria for macrophage activation syndrome. To evaluate their immune responses, serial analyses of serum cytokines/chemokines and flow cytometry were performed. Surges in macrophage-associated cytokine levels were observed in proportion to the severity of adverse events within 1\u2009week after AAV vector infusion, suggesting that macrophage activation contributed to the pathogenesis of these adverse effects. Our findings clarify the immunological basis underlying hepatotoxicity in patients after AAV gene therapy. Furthermore, these findings provide a rationale for using various immunosuppressants or chemokine blockers in patients exhibiting severe adverse effects.",
"42400730": "ID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1\u03b1 pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers \u03b1-synuclein accumulation and affects autophagy; both markers of PD. Combining nano\u2011resveratrol formulations with L\u2011DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co\u2011administration with EGCG has shown synergistic neuroprotection in vitro (SH\u2011SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.",
"42401196": "ID: 42401196\nTitle: The Core Compendium of the European Society of Emergency Medicine Ultrasound Curriculum.\nAbstract: The diversity of healthcare systems across Europe has predictably resulted in significant variations in point-of-care ultrasound (PoCUS) training and practice for emergency medicine (EM). To encourage a more synchronized approach and address these inconsistencies, the European Society of Emergency Medicine (EUSEM) chartered its ultrasound section to develop a comprehensive curriculum compendium that should serve as a foundational guide for European Emergency Medicine PoCUS clinical and educational guidelines and policies. Under the leadership of a dedicated task force, the EUSEM ultrasound section developed this compendium to provide a structured, tiered framework designed to meet the needs of physicians at every skill level, from novice to advanced users. The compendium emphasizes applications that are currently practiced in different and diverse emergency departments in Europe, including a broad range of topics. An important goal was allowing flexibility to accommodate the unique resources and challenges of different healthcare environments, so that EM physicians can achieve PoCUS competencies matching their local circumstances and needs. To achieve this goal, good educational and clinical stewardship throughout this process is a key part to the success of advancing PoCUS in European EM. This compendium is intended as a resource for creating standardized yet adaptable training pathways. It represents a major step toward harmonizing and advancing PoCUS practice in European EM. Die Vielfalt der verschiedenen Gesundheitssysteme in Europa hat dazu gef\u00fchrt, dass grosse Unterschiede in der Ausbildung und Anwendung des Point-of-Care-Ultraschalls (PoCUS) in der Notfallmedizin bestehen. Um einen st\u00e4rker synchronisierten Ansatz zu f\u00f6rdern und diesen Unterschieden zu begegnen, hat die Europ\u00e4ische Gesellschaft f\u00fcr Notfallmedizin (EUSEM) ihre Ultraschallsektion damit beauftragt, ein umfassendes Curriculum-Kompendium zu entwickeln. Dieses soll als ein Leitfaden f\u00fcr Europ\u00e4ische Richtlinien und Standards f\u00fcr PoCUS in der klinischen Ausbildung in der Notfallmedizin dienen. Unter der Leitung einer Task Force hat die Ultraschallsektion der EUSEM dieses Kompendium erarbeitet, um Rahmenbedingungen zu schaffen, die den Bed\u00fcrfnissen von \u00c4rztinnen und \u00c4rzten auf jedem Kompetenzniveau - vom Einsteiger bis zum fortgeschrittenen Anwender - gerecht werden. Das Kompendium beinhaltet Ultraschallanwendungen, die in derzeit sehr diversen Notfallstationen in ganz Europa praktiziert werden, und deckt daher ein breites Spektrum PoCUS-Anwendungen in der Notfallmedizin ab. Ein zentrales Ziel dieser Arbeit war es, Flexibilit\u00e4t zu erm\u00f6glichen, um die spezifischen Merkmale wie auch Ressourcen der jeweiligen Gesundheitssysteme zu ber\u00fccksichtigen, sodass Notfallmediziner:innen PoCUS-Kompetenzen erwerben k\u00f6nnen, die ihren lokalen Gegebenheiten und Anforderungen entsprechen. Um das Ziel der Weiterentwicklung von PoCUS in der europ\u00e4ischen Notfallmedizin zu erreichen, ist ein entscheidender Erfolgsfaktor eine gute Begleitung sowohl in der klinischen Anwendung, wie auch in der Ausbildung. Dieses Kompendium soll als Grundlage zur Entwicklung standardisierter, zugleich aber anpassungsf\u00e4higer Ausbildungspfade dienen.

"42401978": "ID: 42401978\nTitle: Regional wasteosome accumulation across neurodegenerative diseases points to a shared underlying mechanism potentially related to glymphatic insufficiency.\nAbstract: The glymphatic system plays a key role in clearing waste products from the brain and is essential for maintaining brain homeostasis. When dysfunctional, it appears to contribute to pathological changes that exacerbate brain disorders, including neurodegenerative diseases. Additionally, wasteosomes, also known as corpora amylacea, are structures that function as waste containers and are thought to increase in response to chronic glymphatic insufficiency. Hence, in this study, we evaluated whether the accumulation and distribution of wasteosomes are compatible with both the potential role of wasteosomes as a hallmark of the chronic glymphatic insufficiency and the presence of this insufficiency in certain neurodegenerative diseases. Accordingly, brain tissue from 185 donors was analysed, including cases of Alzheimer's disease, amyotrophic lateral sclerosis with TDP-43 proteinopathy, frontotemporal lobar degeneration with TDP-43 or tau proteinopathy, and non-diseased controls. Wasteosomes were examined across 28 brain regions comprised within 5 major brain areas, using region-specific scoring systems. Analysis was conducted through variance and covariance analyses, along with decision tree procedures. The findings reveal that wasteosomes are consistently found in specific critical regions, with a higher burden in donors with neurodegenerative diseases compared with controls. These regions are independent of the regional distribution of the underlying proteinopathy, and are potentially associated with glymphatic drainage pathways. From an integrated perspective, although further studies are required, the increased presence of wasteosomes in these critical regions across all diseased groups is consistent with the potential presence of chronic glymphatic insufficiency in these diseases.",
"42402806": "ID: 42402806\nTitle: Very low-amplitude muscle activity increases probability of motor evoked potentials in healthy individuals and in amyotrophic lateral sclerosis.\nAbstract: Muscle contraction increases motor evoked potential (MEP) amplitude, decreasing motor threshold (MT). Correspondingly, trials where baseline EMG amplitude exceeds a specified threshold are often rejected. We aimed to investigate the influence of motor activity below such a threshold of MEP amplitude. We retrospectively analysed TMS-EMG data collected during resting MT (RMT) measurement in 45 healthy control subjects (1794 data points) and 35 people with amyotrophic lateral sclerosis (ALS; 1229 data points). Trials with de-meaned root mean squared (RMS) EMG amplitude of >10\u00a0\u00b5V throughout the 200\u00a0ms prior to stimulation were rejected. Generalised linear mixed-effects models assessed effects of muscle activity below this rejection threshold on the probability of evoking an MEP with peak-to-peak amplitude of \u226550\u00a0\u00b5V. Greater sub-rejection-threshold activity significantly increases MEP probability in control subjects and people with ALS. Models predicted a 38%-43% increase in MEP probability when baseline RMS-EMG amplitude increased from 1 $\\hskip.001pt 1$ to 9\u00a0\u00b5V. Sub-rejection-threshold baseline activity was significantly greater in ALS than control subjects. Below a typical rejection threshold, greater baseline RMS-EMG amplitudes markedly increase the probability of evoking MEPs with peak-to-peak amplitude of \u226550\u00a0\u00b5V. Effects of sub-rejection-threshold muscle activity should be accounted for when comparing RMT measures, particularly between cohorts where such activity differs, such as ALS and control subjects.",
"42403529": "ID: 42403529\nTitle: Paid homecare worker support for people living with motor neurone disease: A secondary analysis of people living with motor neurone disease and family member perspectives.\nAbstract: People living with motor neurone disease (MND) increasingly receive complex, life-sustaining interventions at home, including ventilation, tube feeding, and cough assist support. These demands place substantial strain on family carers and often require input from paid homecare workers. Despite their essential role, little is known about how homecare workers contribute to complex MND care, how they integrate within multidisciplinary teams, or how families experience their involvement. To examine people living with MND and family members' perspectives of homecare worker roles, responsibilities, relationships when complex interventions are required. A qualitative secondary analysis of data from two prior studies exploring home ventilation and tracheostomy ventilation in MND. Seven relevant NVivo nodes and 33 sub-nodes from interviews with 68 participants were re-coded using a deductive framework. Fourteen new nodes and 11 sub-nodes were generated and organised into three themes: care commissioning and provision; relationships; and the home environment. Participants described fragmented and inconsistent care commissioning, requiring families to advocate persistently for adequate support. Challenges included funding barriers, high staff turnover, and limited MND-specific knowledge, which undermined trust and compromised safe, effective care. Relationships with homecare workers ranged from highly valued, stable partnerships to strained interactions shaped by competence concerns, emotional labour, and mismatched expectations. The presence of homecare workers and medical equipment transformed the home into a quasi-clinical space, reducing privacy, disrupting routines, and requiring households to adapt around care provision. Yet strong relationships with homecare workers could enhance quality of life. Homecare workers play a critical role in delivering complex home-based MND care, yet quality is inconsistent. Improving training, stabilising staffing, supporting care coordination, and preparing families for the relational and environmental impact of homecare are essential for fostering sustainable, trusted care relationships, and improving outcomes for people living with MND and their families. Paid homecare support for people with motor neurone disease: Insights from people with MND and their families This study explores how people living with motor neurone disease (MND), and their family members, experience support from paid homecare workers when complex medical interventions, such as ventilation, feeding tubes, suction and hoists are needed at home. As care needs increase, families often need help from paid homecare workers, yet no research has asked families about what this support is like. To address this, we re-analysed interview data from two earlier studies about living with home ventilation in MND, and developed three main themes: Care commissioning and provision: Participants described the process of securing a care package as confusing and often exhausting, with multiple organisations involved. Families frequently had to push to get the support they needed. Problems included shortages of trained staff, high staff turnover, and delays caused by complex funding rules. Relationships with homecare workers: Good homecare workers made a huge positive difference. Relationships with homecare workers ranged from highly positive, built on trust, skill and becoming \u2018part of the family\u2019, to strained, particularly when workers lacked MND-specific training or confidence with equipment. Trust was crucial: when present it eased pressure on families but when absent it increased stress and vigilance. Impact on the home environment: Having carers in the house, changed home life, reducing privacy, disrupting household routines, and living spaces became filled with medical equipment and ever-present homecare workers. Families described feeling like hosts in their own homes and sometimes having to manage the emotional labour of being polite or accommodating even when exhausted. Overall, the study shows that homecare workers play an essential role in complex MND care, but quality is inconsistent. Better coordination and support for families to manage these close relationships within the home are vital to reduce pressure on families and improve quality of life.",

While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p\u202f>\u202f0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p\u202f>\u202f0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD\u202f=\u202f6.6) to discharge (30.97, SD\u202f=\u202f5.84) and were maintained at 1-month follow-up (30.21, SD\u202f=\u202f6.7; p\u202f=\u202f0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline\u202f=\u202f33.3; 1-month follow-up\u202f=\u202f28.61; p\u202f=\u202f0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline\u202f=\u202f9.63; 1-month follow-up\u202f=\u202f7.38; p\u202f=\u202f0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function.",
"42404433": "ID: 42404433\nTitle: Beyond motor neurons: peripheral TDP-43 pathology in skeletal muscle and intramuscular nerves in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive neurodegenerative disease characterized by accumulation of the 43-kDa TAR DNA-binding protein (TDP-43). This neuropathological signature has been well documented within the CNS; however, recent findings indicate that the phosphorylated TDP-43 additionally deposits in peripheral tissues, including skeletal muscle and intramuscular nerves. These data warrant a change of view from a neurocentric perspective of amyotrophic lateral sclerosis pathogenesis towards a broader concept of TDP-43 proteinopathy extending both within and beyond the nervous system. In this review, we focus on current evidence supporting the presence of TDP-43 pathology in amyotrophic lateral sclerosis skeletal muscle, examining its topographic distribution, molecular characteristics and associations with intramuscular nerve bundles. We also discuss the susceptibility of intrinsic muscle cells, disrupted axonal transport and impairment in protein quality control. Phosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease. Moreover, we discuss the relevance of these findings to amyotrophic lateral sclerosis pathogenesis and potential therapeutic implications.",
"42404435": "ID: 42404435\nTitle: Value of synaptic proteins as biomarkers in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a heterogeneous and rapidly progressing neurodegenerative disorder with limited treatment options. Therefore, there is a critical need for biomarkers that capture the diverse pathophysiological mechanisms underlying disease onset and progression. Emerging evidence suggests that synaptic dysfunction is an early disease mechanism in amyotrophic lateral sclerosis. Using homebrew immunoassays, we explored a panel of pre- and post-synaptic proteins in cerebrospinal fluid of patients with amyotrophic lateral sclerosis (N = 57) and controls (N = 36). The potential value as a biomarker was explored by correlating cerebrospinal fluid levels with clinical parameters and established biomarkers for amyotrophic lateral sclerosis. Higher levels of Neurogranin (NRGN) (P = 0.003) and Vesicle-associated membrane protein 2 (VAMP2) (P = 0.014) were observed in patients with amyotrophic lateral sclerosis compared with controls. VAMP2, Synaptosome-associated protein 25\u2005kDa (SNAP25) and \u03b2-synuclein (SNCB) correlated with individual relative disease stage, but none of the biomarkers correlated with disease progression rate. High levels of SNAP25 predicted worse survival in a univariate and stepwise multivariable analysis, but significance did not persist upon including Neurofilament light chain (NfL) levels. Synaptic proteins did not correlate with cerebrospinal fluid levels of neurofilaments or biomarkers of neuroinflammation, suggesting that they reflect different pathological mechanisms in amyotrophic lateral sclerosis. Our findings warrant further investigation to determine whether increased cerebrospinal fluid levels of synaptic proteins reflect synaptic breakdown or active release of synaptic proteins. This will help elucidate how synaptic dysfunction or damage contributes to elevated levels of synaptic markers in amyotrophic lateral sclerosis, and its underlying value as biomarker.",
"42404802": "ID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.",
"42405014": "ID: 42405014\nTitle: Cholesterol in amyotrophic lateral sclerosis: a bystander, a biomarker, or a target?\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss. In addition to the different pathogenic mechanisms, in recent years, increasing attention has been directed toward the role of lipid metabolism in ALS pathogenesis, although the clinical relevance of lipid alterations in ALS may differ from their well-established role in cardiovascular disease. This review critically examines the multifactorial relationship between cholesterol and ALS through three perspectives: (1) as a risk factor for disease onset, (2) as a prognostic biomarker of disease progression, and (3) as a potential therapeutic target. Epidemiological and genetic studies suggest a complex and sometimes contradictory association between lipid profile and ALS risk. Elevated LDL-cholesterol and total cholesterol have been linked to increased disease susceptibility in some cohorts, with Mendelian randomization studies supporting a potential causal role. Conversely, evidence regarding HDL-cholesterol remains conflicting and may be influenced by sex-specific and metabolic factors. As a prognostic biomarker, hyperlipidemia has been variably associated with prolonged survival in ALS patients; however, these findings often lose significance after adjusting for body mass index and nutritional status, suggesting that lipid levels may reflect systemic metabolic reserve rather than directly modulating disease progression. Pharmacological modulation of cholesterol reveals further complexity. While statins are generally not associated with increased ALS risk in clinical studies, preclinical models show divergent effects: some statins accelerate disease progression, while others like lovastatin may be protective. Other lipid-lowering drugs, including fibrates and PCSK9 inhibitors, may also influence ALS-related pathways beyond cholesterol lowering, although their potential role remains to be clarified.",
"42407013": "ID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders."
