abstract = {Neurodegenerative and neuroinflammatory diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis, are increasingly associated with disruption of the microbiota-gut-brain axis. Common alterations include reduced beneficial microbial taxa, impaired short-chain fatty acid production, intestinal and blood-brain barrier dysfunction, and sustained inflammatory responses. These findings support the development of microbiota-targeted dietary interventions. This review summarizes current evidence on polyphenols, bioactive peptides, and pectin-derived oligosaccharides (POS) as prebiotic or prebiotic-like compounds with potential activity through the microbiota-gut-brain axis. Particular attention is given to structure-function relationships, host-microbe interactions, and the sustainable recovery of these compounds from food by-products. Preclinical studies suggest that these bioactives may reduce microglial activation, improve mitochondrial function, strengthen intestinal and blood-brain barrier integrity, and enhance cognitive or motor performance. Early clinical studies also indicate possible benefits on mood, selected cognitive outcomes, metabolic regulation, and inflammatory biomarkers, although evidence remains limited. Microbiota-derived metabolites from polyphenols, such as urolithins, together with glycomacropeptide and POS, appear to be key mediators. However, clinical validation in major neurodegenerative diseases remains fragmented. Standardized formulations, mechanistic trials, harmonized endpoints, and precision-nutrition strategies are required to confirm their therapeutic potential.},

abstract = {INTRODUCTION: Neurofilament light chain (NfL) is a structural axonal protein measurable in CSF and blood, increasingly investigated as a biomarker of neuroaxonal injury in clinical and research contexts. This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions.

METHOD: A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised.

RESULTS: 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions.

CONCLUSION: Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint.},

Structural MRI, diffusion tensor imaging (DTI), functional MRI (fMRI), positron emission tomography (PET), hybrid PET/MRI and molecular imaging have transformed our ability to investigate neurodegeneration in vivo non-invasively. This review highlights updated information on how each imaging modality offers a unique window into different disease pathophysiology including regional atrophy, amyloid-β, tau, dopaminergic terminal degeneration, synaptic density (SV2A), and neuroinflammation. We also focused on the translational and evidence supporting biomarkers, appropriate use criteria for amyloid and tau PET imaging, and standardized quantification methods such as the Centiloid scale. The growing role of multimodal fusion, where imaging is increasingly integrated with scalable fluid biomarkers to enable "blood-first" strategies where high-risk patients are selectively referred to advanced imaging, improving feasibility and equity. Despite tremendous progress, there are still issues with their standardization, sensitivity, specificity, and clinical translation. Moreover, the review emphasizes the frontiers of α-synuclein and glial state-specific PET ligands, advanced diffusion models, and dynamic connectivity analysis to support precision medicine and mechanism-based trial design for NDDs.},

abstract = {OBJECTIVE: This study aimed to systematically evaluate the therapeutic efficacy of electroacupuncture (EA) in amyotrophic lateral sclerosis (ALS) and to elucidate the underlying neurobiological mechanisms by synthesizing preclinical evidence.

METHODS: According to the PICOS principle, relevant studies were searched in the following databases: PubMed, Web of Science, Embase, Cochrane Library, Scopus, and CNKI. Search terms and strategies were determined based on MeSH terms. The methodological quality of the included studies was assessed using the SYRCLE's Risk of Bias tool and the CAMARADES checklist. Meta-analysis was performed using Stata 15.0 and Rstudio software.

RESULTS: Seventeen studies involving 372 animals were included. The quality scores of the included studies ranged from 5 to 8, with an average score of 7. The meta-analysis of the primary outcome, the rotarod test score, showed a significant improvement in the EA group compared to the control group [SMD = 3.31, 95% CI (2.05, 4.57), Z = 5.151, p < 0.001], indicating that EA can enhance motor function in ALS mice. Regarding secondary outcomes, EA intervention alleviated neuroinflammation, promoted neuronal survival, improved axonal regeneration inhibition, and stabilized RNA metabolism homeostasis. Consequently, it slowed disease progression, improved motor performance, prolonged survival time, and effectively protected motor neurons at the histopathological level (p < 0.05). These findings underscore the potential of EA as a promising multimodal therapeutic strategy for ALS. For the heterogeneity observed in the rotarod test, sensitivity analysis, subgroup analysis, and meta-regression did not identify its source. However, potential publication bias was detected, which might contribute to the heterogeneity. The heterogeneity for other outcome measures might originate from differences in stimulation parameters (e.g., waveform), acupoint selection, or treatment duration.

CONCLUSION: This meta-analysis demonstrates that EA confers significant neuroprotective benefits in preclinical ALS models, primarily through multi-target modulation of key pathological processes such as neuroinflammation, aberrant cell death signaling, and RNA metabolism. These preclinical findings underscore the potential of electroacupuncture as a complementary neuroprotective strategy and warrant further investigation in rigorous clinical trials.

abstract = {BACKGROUND: Several user-written Stata codes exist for trial-based economic evaluations, but they lack assessment and guidance. This study aimed to identify and compare publicly available user-written Stata codes for trial-based economic evaluations.

METHODS: A focused literature search of Ovid Medline, SSC Archive, The Stata Journal and Google Scholar was conducted to identify relevant codes to June 2025. Codes were applied to data from two clinical trials, both featuring missing data and covariate adjustment. Codes were compared in terms of their ability to estimate key economic parameters and produce graphical outputs and functionality in handling four common statistical challenges: correlated costs and effects, covariate adjustment, skewed costs and effects, and missing data.

RESULTS: We identified eight codes reported in four publications: codes for assessing health economic agreement (Gallacher et al.), sampling uncertainty for cost-effectiveness analysis (Glick et al.) and codes addressing missing data (Mutubuki et al. and Faria et al.). Gallacher et al.'s codes reported lower incremental quality-adjusted life years (QALYs) and net monetary benefit than Glick's et al.'s codes. Mutubuki et al. and Faria et al.'s codes produced comparable incremental costs and QALYs, though Faria et al. yielded wider confidence intervals in cost estimates.

DISCUSSION: Differences in estimates across statistical approaches show that code choice can influence economic evaluation results. Some codes were better suited for generating basic economic outputs, whereas others provide more comprehensive analyses or address specific statistical challenges including missing data. However, no single code provided all key outputs while addressing the main statistical challenges.},

Resveratrol, a polyphenolic phytoalexin mainly found in grapes and red wine, is a promising treatment candidate due to its diverse biological effects and neuroprotective properties. This review demonstrates the regulatory effects of resveratrol on cellular signaling pathways linked to NDs and its neuroprotective mechanisms. Resveratrol enhances neuronal survival, boosts mitochondrial biogenesis, and mitigates oxidative stress by affecting key molecular pathways, including SIRT1/AMPK, PI3K/Akt, MAPK, and Nrf2/ARE. The PI3K/Akt and ERK1/2 pathways promote neuronal regeneration by modulating pro-apoptotic and anti-apoptotic factors. Resveratrol inhibits NF-κB, reducing cytokine release and microglial activation, thereby exhibiting anti-inflammatory properties. It improves cognitive function, synaptic plasticity, and neuronal survival. Despite an increasing pharmacological profile, its practical applicability is limited by inadequate bioavailability, rapid metabolism, and restricted brain penetration. This review demonstrates resveratrol's effect on interconnected signaling networks related to neurodegeneration. We critically compare evidence from preclinical and clinical studies, demonstrating both therapeutic potential and translational limitations. Emerging nanotechnology-based delivery strategies are demonstrated to overcome bioavailability and blood-brain barrier penetration challenges. These insights provide a translational perspective for the future development of resveratrol-based interventions in NDs.},

Extracellular vesicles (EVs) have emerged as potential minimally invasive biomarkers for ALS, but studies vary widely in methodology and reproducibility. We conducted a systematic review and meta-analysis to evaluate the diagnostic potential of EV-associated proteins and RNAs in ALS. Following PRISMA guidelines, we searched PubMed and EMBASE from inception to May 21st, 2026. Forty-one studies met inclusion criteria. Where published summary statistics were available, these were used directly; where they were not, data were reconstructed from figures or obtained from authors and re-analyzed to derive standardized effect sizes and exploratory diagnostic accuracy estimates. Random-effects models were used for continuous outcomes, and diagnostic accuracy was assessed using hierarchical summary ROC and bivariate random-effects models. Publication bias was evaluated using Begg, Egger, and funnel plots. EV-associated TDP-43 was the most frequently studied protein. Meta-analysis of five studies showed a moderate but non-significant increase in EVs from ALS vs. controls (SMD = 1.30) with high heterogeneity (I = 97.8%). Sixteen studies assessing EV-RNA biomarkers showed minimal overlap and limited independent replication. Diagnostic accuracy meta-analysis across 11 studies yielded moderate performance (AUC = 0.839). No publication bias was found across both meta-analyses. EV biomarkers for ALS show biological promise but are limited by methodological variability and insufficient replication. This work highlights the need for standardized protocols, transparent data sharing, and independent validation.},

Accumulating evidence indicates that TREM2 is neither uniformly protective nor uniformly pathogenic; rather, its biological effects are highly context-dependent, governed collectively by disease stage, pathological substrates, cellular compartments, and the local microenvironment. By coupling with TYROBP/DAP12 or DAP10, TREM2 actively drives the state remodeling of pathology-associated microglia. It profoundly influences the onset and progression of neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS), as well as acute central nervous system injuries, including ischemic stroke, spinal cord injury (SCI), and traumatic brain injury (TBI). Concurrently, soluble TREM2 (sTREM2) holds significant potential not only as a biomarker but also as a context-dependent effector molecule actively participating in pathological regulation. This review synthesizes current advancements by focusing on four core themes: the structural and signaling logic of the TREM2 axis; its regulation of disease-associated microglia (DAM) remodeling; the cross-disease significance of sTREM2; and the mechanistic basis for the divergent outcomes observed with TREM2-targeted therapies across different experimental models and disease stages. The objective is to elucidate the context-dependent roles of TREM2 by analyzing consensus mechanisms, sources of discrepancy, and translational implications, thereby providing a theoretical framework and strategic direction for more precise TREM2-targeted interventions.},

abstract = {OBJECTIVE: This scoping review aims to identify existing evidence on the lived experiences of people living with HIV and treated for anal cancer, and to identify what aspects of health and well-being are addressed in clinical guidance.

DESIGN: A preregistered protocol (Open Science Framework, 2025) guided the review. We followed the Arksey and O'Malley framework, incorporating Levac et al's refinements around stakeholder consultation. Joanna Briggs Institute (JBI) guidance informed eligibility and data for charting, and reporting adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines.

DATA SOURCES: Systematic searches were performed across multiple databases, including CINAHL, MEDLINE, PsycINFO and Embase, using EBSCOhost and Ovid, supplemented handsearching reference lists. Two search strategies were used: one for research studies and one for clinical guidelines.

ELIGIBILITY CRITERIA: Sources included people living with HIV treated for anal cancer, capturing lived experiences directly through qualitative studies or indirectly via quantitative patient-reported outcomes and/or health-related quality of life. Guidelines addressing HIV or anal cancer were also included.

DATA CHARTING AND SUMMARIES: Data were charted to capture patient experiences and outcomes on living with and beyond cancer, and how these are addressed in clinical management and guidance, including biomedical, psychosocial, sexual and functional aspects, and patient-reported outcomes.

RESULTS: Of 945 records, three studies and four guidelines met criteria. No study focused exclusively on people living with HIV; findings reflect broader anal cancer populations with HIV-positive subsets. Studies addressed aspects of health-related quality of life which we mapped into physical, psychosocial and sexual domains. Clinical guidance prioritised treatment dosage and survival, with limited attention to broader effects. Stakeholders highlighted that existing research and guidance miss important nuances of lived experience and care needs.

CONCLUSIONS: No identified research solely explored the lived experiences of people living with HIV treated for anal cancer, leaving guidance non-specific and biomedical. The identified domains offer a starting point for future research; however, to inform patient-centred care, stakeholders emphasised the need to understand how living with HIV and anal cancer shapes health needs.},

abstract = {Neurodegenerative diseases are characterized by progressive neuronal dysfunction and loss resulting from impaired proteostasis and vesicular trafficking. Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival.},

abstract = {BACKGROUND AND OBJECTIVE: Respiratory failure is the primary cause of mortality in amyotrophic lateral sclerosis (ALS), usually caused by progressive neuromuscular respiratory weakness. Standard pulmonary function tests (PFTs) such as maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and both supine and upright forced vital capacity (FVC) are crucial for objective measurements of diaphragmatic weakness but have limitations, including dependence on the patient's performance and the inability to detect early, subclinical diaphragmatic impairment or be used effectively in patients with bulbar symptoms. Radiological assessments, particularly dynamic imaging, have emerged as potential objective tools for evaluating respiratory function. This review comprehensively summarizes findings on the use of diaphragmatic ultrasound (DUS), dynamic chest magnetic resonance imaging (MRI) and deep learning (DL)-based chest computed tomography (CT) for assessing lung function in ALS patients.

METHODS: Key radiological metrics include diaphragm thickness (DT), thickening fraction during inspiration, real-time diaphragmatic excursion, lung diameter changes and changes in pulmonary length and area. These measures have been compared with conventional PFTs in various studies to validate their use for diagnostic accuracy, particularly in early stages of disease.

KEY CONTENT AND FINDINGS: DUS is a non-invasive, widely available tool that strongly correlates with PFT measurements, especially FVC, MIP, and sniff nasal inspiratory pressure (SNIP). Dynamic measures, such as excursion and velocity, appear more sensitive to early dysfunction than thickness alone. Chest dynamic MRI has also shown significant correlations with spirometric parameters. Small cohort studies indicate that dynamic chest MRI is a superior, sensitive tool for detecting early respiratory impairment in asymptomatic patients with normal spirometry.

CONCLUSIONS: Radiological assessments, primarily DUS, DL-based chest CT and dynamic MRI, offer valuable, objective, and non-invasive methods for monitoring respiratory muscle strength in ALS. These techniques serve as complementary tools to traditional PFTs, particularly in selected clinical scenarios such ALS patients with early disease, bulbar involvement and unable to perform PFTs. Further longitudinal research with larger cohorts is needed to standardize protocols and validate their role as early parameters to guide the timely initiation of supportive interventions like non-invasive ventilation (NIV).},

These diseases share common pathological mechanisms including oxidative stress, mitochondrial impairment, chronic neuroinflammation, protein misfolding, and epigenetic dysregulation. Current therapies offer only symptomatic relief and fail to halt disease progression. Recent advances in transcriptomics and proteomics have enabled the identification of shared molecular pathways and druggable targets across multiple neurodegenerative diseases. The key targets, such as BDNF-TrkB, TREM2, SIRT1, PINK1-Parkin, GSK-3β, NLRP3, and mTOR have shown promise in preclinical models, offering opportunities for broad-spectrum therapeutic development. Importantly, blood-brain barrier disruption and neuroinflammatory crosstalk exacerbate disease pathology and hinder drug delivery. Innovative strategies involving nanocarriers, gene therapy, and epigenetic modulation are emerging to overcome these barriers. This review highlights the convergence of disease mechanisms, discusses common molecular signatures and therapeutic vulnerabilities, and explores novel small molecular interventions targeting shared pathways mainly in AD and PD. A deeper understanding of aging-associated molecular dysfunction is essential to design sustainable, disease-modifying therapeutics with cross-disease relevance.},

We also address the contribution of oxidative stress, neuroinflammation, and aging to proteasome dysregulation. Finally, we highlight emerging therapeutic strategies aimed at restoring proteasome function, including pharmacological activation, modulation of proteasome assembly and stability, and targeted protein degradation approaches.

abstract = {Vitamin D has long been recognized for its role in calcium homeostasis and bone metabolism; however, it is now emerging as an important regulator of central nervous system (CNS) function. Recent evidence suggests that vitamin D signaling contributes to the pathogenesis and progression of several neurodegenerative disorders. Vitamin D exerts neuroprotective effects through multiple mechanisms, including regulation of calcium homeostasis, modulation of immune responses, reduction in oxidative stress, stimulation of neurotrophic factors, and maintenance of blood-brain barrier (BBB) integrity. Vitamin D receptors and metabolizing enzymes are widely distributed across several brain regions, highlighting their direct involvement in neuronal function. This review summarizes the biosynthesis, metabolism, and signaling pathways of vitamin D. It explores its role in neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), stroke, and traumatic brain injury (TBI). Evidence from experimental and clinical studies indicates that vitamin D deficiency is associated with an increased risk and severity of these conditions, while supplementation may provide therapeutic benefits.},

abstract = {Neurodegenerative diseases, such as Alzheimer's, Parkinson's, and Amyotrophic lateral sclerosis, are distinguished by progressive neuronal dysfunction caused primarily by oxidative stress, mitochondrial impairment, neuroinflammation, and redox imbalance. Growing evidence suggests that indole-derived compounds have significant neuroprotective potential due to their antioxidant, anti-inflammatory, and redox-modulating properties. This review summarizes the structural and biological significance of indole scaffolds, focusing on the mechanisms by which natural, endogenous, microbiota-derived, and synthetic indole compounds protect neuronal networks. Indole-3-carbinol, 3,3'-diindolylmethane, indole-3-propionic acid, and melatonin are major indole derivatives that control important neuroprotective pathways like Nrf2/ARE signaling, mitochondrial bioenergetics, neurotrophic factor expression, apoptotic regulation, and suppression of proinflammatory mediators. These compounds also maintain synaptic plasticity, reduce reactive oxygen species production, and improve neuronal survival in neurodegenerative disease models. Additionally, updated information from translational and clinical research indicates that indole-based compounds may have promising therapeutic applications; however, obstacles like low bioavailability, metabolic instability, and blood-brain barrier penetration continue to be major obstacles to clinical application. Development in nanoparticle delivery systems, microbiome-targeted interventions, and rational structural optimization may improve therapeutic efficacy and translational potential. Overall, indole-derived compounds are a versatile class of redox modulators with potential applications in the prevention and treatment of neurodegenerative diseases via integrated antioxidant and neuroprotective mechanisms.},

abstract = {BACKGROUND: Respiratory decline is prognostically important in amyotrophic lateral sclerosis (ALS), but the efficacy of respiratory muscle training (RMT) remains uncertain. We synthesized randomized evidence on respiratory and related outcomes.

METHODS: We searched databases, specialized registers, and trial registries through June 19, 2025, for randomized RMT trials in ALS. Risk of bias was assessed with the Cochrane tool. Random-effects meta-analyses reported standardized mean differences (SMDs) with 95% confidence intervals (CIs), and certainty was rated with GRADE.

RESULTS: Six studies were included; five concurrently randomized trials contributed quantitative data, whereas Pinto 2013 was retained for qualitative context. RMT improved maximal expiratory pressure (MEP; SMD 0.387, 95% CI 0.192-0.581; P = 0.008) and showed small favorable effects on maximal inspiratory pressure (MIP; SMD 0.156, 95% CI 0.089-0.224; P = 0.005), sniff nasal inspiratory pressure (SNIP; SMD 0.216, 95% CI 0.039-0.392; P = 0.034), peak expiratory flow (PEF; SMD 0.205, 95% CI 0.088-0.323; P = 0.017), and ALSFRS-R (SMD 0.214, 95% CI 0.039-0.388; P = 0.030). Forced vital capacity showed a borderline favorable trend (SMD 0.129, 95% CI - 0.003 to 0.262; P = 0.053). Low heterogeneity estimates were imprecise because most endpoints included only three to four small studies. Certainty was moderate for MIP, low for MEP, FVC, and PEF, and very low for SNIP and ALSFRS-R. Exploratory analyses identified no reliable effect modifiers.

CONCLUSIONS: RMT was associated with small, directionally consistent improvements mainly in pressure- and flow-based outcomes, whereas effects on FVC and longer-term clinical outcomes remain uncertain. RMT may be considered an individualized adjunct to ALS respiratory care, not a disease-modifying therapy. Larger, longer, standardized trials with patient-important endpoints are needed.},

Exosomes have emerged as key mediators of central nervous system communication and are increasingly central to the biology of neurodegeneration. These nanoscale vesicles transport proteins, lipids, and nucleic acids across cellular and anatomical barriers, influencing synaptic function, immune signaling, and metabolic homeostasis. Under pathological conditions, exosomes facilitate the spread of misfolded proteins such as amyloid-β, p-tau, α-synuclein, and TDP-43, thereby accelerating network-level degeneration. At the same time, their cargo exhibits disease-specific molecular signatures detectable in peripheral biofluids, supporting their development as minimally invasive biomarkers for early diagnosis and longitudinal monitoring. Advances in exosome engineering further underscore their potential as therapeutic delivery vehicles capable of crossing the blood-brain barrier and targeting pathogenic pathways with RNA-based therapeutics, proteins, or gene-editing systems. Together, these findings position exosomes as pivotal contributors to both the mechanistic progression and translational targeting of neurodegenerative diseases.},

However, validity of equations, as alternatives to reference standards for assessing these parameters in ALS, is unclear. This systematic review evaluates criterion validity of equations to estimate body composition and energy expenditure in ALS.

METHODS: Four electronic databases (EMBASE, MEDLINE, CINAHL and Cochrane) were systematically searched from inception until July 7th, 2025. Studies were included if criterion validity of an instrument or method for estimating body composition or energy expenditure was examined in people diagnosed with ALS. Methodological quality was assessed using the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) risk of bias checklist. Criterion validity was rated as sufficient (+), indeterminate (?) or insufficient (-) based on COSMIN criteria for good measurement properties. Results were qualitatively summarised.

RESULTS: Twelve studies were included: five evaluated the criterion validity of equations to estimate body composition using Bioelectrical Impedance Analysis (BIA) or anthropometry, and seven to estimate resting or total daily energy expenditure. No equation was rated as sufficient for criterion validity across studies.

CONCLUSION: Equations to estimate body composition and energy expenditure should be applied with caution, as no equation exhibited high criterion validity in ALS. ALS-specific equations require further validation, and ideally, new equations tailored to the unique physiological characteristics of ALS should be developed.

Recent studies suggest that in certain neurological disorders, including Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD) and various tauopathies, protein aggregation may be promoted by virus-like particles (VLPs) formed by endogenous retroviruses (ERVs). The molecular mechanisms by which these VLPs contribute to protein aggregation, however, remain enigmatic. Here, we discuss possible molecular mechanisms of ERV-derived VLPs in the formation and spread of protein aggregates. An intriguing possibility is that liquid-like condensates may facilitate the formation of both protein aggregates and ERV-derived VLPs. We also describe how RNA chaperoning, and the encapsulation and trafficking of misfolded proteins, may contribute to protein homeostasis through the elimination of protein aggregates from cells. Based on these insights, we discuss future potential therapeutic opportunities.},

abstract = {BACKGROUND: Several clinical prediction models that aim to guide decisions about the management of periprosthetic joint infections (PJIs) have been developed. While some models have been recommended for use in clinical settings, their suitability remains uncertain.

METHODS: We systematically reviewed and critically appraised all multi-variable prediction models for the treatment of PJI. We searched MEDLINE, EMBASE, Web of Science, and Google Scholar from inception until 1[st] March 2024 and included studies that developed or validated models that predict the outcome of PJI. We used PROBAST (Prediction model Risk Of Bias ASsessment Tool) to assess the risk of bias and applicability. Model performance estimates were pooled via random effect meta-analysis.

RESULTS: Thirteen predictive models and seven external validations were identified. Methodological issues were identified in all studies. Pooled estimates indicated that the KLIC (Kidney, Liver, Index surgery, Cemented prosthesis, C-reactive protein) score had fair discriminative performance (pooled c-statistic 0.62, 95% CI 0.55-0.69). Both the τ[2] (0.02) and I[2] (33.4) estimates indicated that between-study heterogeneity was minimal. Meta-analysis indicated Shohat et al.'s model had good discriminative performance (pooled c-statistic 0.74, 95% CI 0.57-0.85). Both the τ[2] (0.0) and I[2] (0.0) indicated that between study heterogeneity was minimal.

CONCLUSIONS: Clinicians should be aware of limitations in the methods used to develop available models to predict outcomes of PJI. As no models have consistently demonstrated adequate performance across external validation studies, it remains unclear whether any available models would provide reliable information if used to guide clinical decision making.},

Stem cells are classified based on their differentiation potential into totipotent, pluripotent, and multipotent stem cells. Among them, mesenchymal stem cells (MSCs) are widely used in regenerative medicine due to their tissue regeneration capabilities and ability to differentiate into multiple cell types. Stem cells are being explored for treating neurodegenerative disorders like Parkinson's, Alzheimer's, Huntington's, and amyotrophic lateral sclerosis (ALS). These conditions result from progressive neuronal degeneration, leading to irreversible damage. Challenges such as cell survival, immune rejection, tumor formation, and ethical concerns related to embryonic stem cells need to be addressed. Nanotechnology is emerging as a tool for enhancing stem cell therapy, improving targeted delivery and effectiveness. Nanoparticles possess the ability to create microenvironments as substrates, facilitate targeted administration, and enable real-time, precise imaging of stem cells. This review explores the integration of stem cells and nanotechnology as regenerative medicine tool for neurodegenerative disease treatment, analyzing current strategies and therapeutic approaches. Integrating nanotechnology with stem cell therapy may significantly improve targeted delivery and enhance regenerative outcomes for neurodegenerative disorders.},

abstract = {Neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS) and Frontotemporal Dementia (FTD) share key pathological features, including neuroinflammation, oxidative stress, mitochondrial dysfunction, autophagic dysfunction, and DNA damage. By identifying cytosolic DNA and triggering the type I interferon response, the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway regulates neuroinflammation. Dysregulated cGAS-STING signaling has been linked to neuroinflammation and neuronal degeneration across multiple neurodegenerative conditions. In many neurodegenerative disorders, neuroinflammation is mediated by the cGAS-STING pathway. Mitochondrial malfunction and impaired autophagy cause cytosolic DNA buildup in Huntington's, Parkinson's, and Alzheimer's diseases, which activates cGAS-STING and drives chronic inflammation. This pathway is triggered by TDP-43 pathology and nucleic acid dysregulation in ALS and FTD, which leads to neuronal destruction. Both central demyelination and peripheral immunological responses are linked to cGAS-STING activation in multiple sclerosis. Various inhibitors, such as RU.521, H-151, and naturally occurring compounds like metformin, potentially attenuate cGAS-STING-mediated neuroinflammation and associated pathologies. H-151 significantly decreased the expression of pro-inflammatory markers in murine macrophage J774 cells activated with cGAMP: TNF-α by 68 %, IFN-β by 84 %, and CXCL10 by 96 %. cGAS-STING inhibitors target neuroinflammation, offering a disease-modifying approach unlike current symptomatic treatments. However, challenges like blood-brain barrier penetration, off-target effects, and immune suppression hinder clinical translation, necessitating optimized drug delivery and immune modulation. With a focus on its potential for future clinical applications, this review explores the role of the cGAS-STING pathway in neurodegeneration and new treatment approaches.},

abstract = {BACKGROUND: Neurological disorders, ranging from common conditions like Alzheimer's disease that is a progressive neurodegenerative disorder and remains the most common cause of dementia worldwide to rare disorders such as Angelman syndrome, impose a significant global health burden. Altered facial expressions are a common symptom across these disorders, potentially serving as a diagnostic indicator. Deep learning algorithms, especially convolutional neural networks (CNNs), have shown promise in detecting these facial expression changes, aiding in diagnosing and monitoring neurological conditions.

OBJECTIVES: This systematic review and meta-analysis aimed to evaluate the performance of deep learning algorithms in detecting facial expression changes for diagnosing neurological disorders.

METHODS: Following PRISMA2020 guidelines, we systematically searched PubMed, Scopus, and Web of Science for studies published up to August 2024. Data from 28 studies were extracted, and the quality was assessed using the JBI checklist. A meta-analysis was performed to calculate pooled accuracy estimates. Subgroup analyses were conducted based on neurological disorders, and heterogeneity was evaluated using the I[2] statistic.

RESULTS: The meta-analysis included 24 studies from 2019 to 2024, with neurological conditions such as dementia, Bell's palsy, ALS, and Parkinson's disease assessed. The overall pooled accuracy was 89.25% (95% CI 88.75-89.73%). High accuracy was found for dementia (99%) and Bell's palsy (93.7%), while conditions such as ALS and stroke had lower accuracy (73.2%).

CONCLUSIONS: Deep learning models, particularly CNNs, show strong potential in detecting facial expression changes for neurological disorders. However, further work is needed to standardize data sets and improve model robustness for motor-related conditions.},

Patient-centred care is central to bringing about meaningful improvements to quality of life. This review addresses the lack of consolidated evidence on what matters most to people with ALS (pwALS) by synthesizing 44 preference-based studies covering six different treatment and intervention categories. Data-based convergent synthesis identified five overarching factors influencing preferences: ease of use, accessibility, making life easier, autonomy, and safety/reliability. Simplifying and enhancing accessibility of treatment delivery across disease stages aligns with the nature of neurodegenerative disorders such as ALS, where function declines as the disease progresses. The value in perceived and real control reflects the profound impact ALS has on an individual's independence. Safety and reliability are crucial for people with ALS and are recognized as fundamental requirements for quality healthcare. The themes identified in this review can inform the attributes of preference elicitation methods. Systematically varying the levels of these attributes elicits quantitative measures of preferences. These findings can be used to inform and develop healthcare policy and clinical practice in ALS care. Specifically, preferences related to drug treatments can then be integrated into target product profiles (TPPs) to align drug development with the needs and values of pwALS. Integrating patient preferences into clinical practice promotes patient-centred care, increasing both patient satisfaction and treatment effectiveness.},

Notably, the FDA has approved three clinical applications for combating SMA, utilizing viral vectors delivered via intravenous and intrathecal injections. However, gene therapy for other NDDs remains in clinical trials, necessitating improvements in viral vectors, exploration of new vectors, optimization of delivery routes, and further investigation into pathogenesis to identify novel targets.

abstract = {Amyotrophic lateral sclerosis (ALS) is a neurological disease marked by the degeneration of motor neurons, leading to muscle weakness and paralysis. While the cause of ALS is uncertain, research indicates that changes in the gut microbiome may influence the disease's progression. This chapter explores how alterations in gut microbiota affect the enteric neuromuscular system (ENS) in ALS. In ALS patients, disrupted gut microbiota are linked to the brain-gut axis, impacting both gastrointestinal function and neuronal health. Studies show that microbial changes are associated with inflammation, immune instability, and neurodegeneration, which exacerbate the disease. Gastrointestinal issues like constipation and dysphagia in ALS are tied to ENS dysregulation. Understanding the connections between the gut microbiome, ENS, and central nervous system (CNS) may lead to novel therapies targeting neurodegeneration and microbial dysbiosis in ALS.},

abstract = {Neurons are very susceptible to oxidative stress. They are the major consumers of oxygen in the brain, which is used to provide energy through oxidative phosphorylation, the major source of reactive oxygen species (ROS). In addition, compared to other tissues, neurons have lower levels of catalase and glutathione and increased susceptibility to lipid peroxidation due to the elevated levels of unsaturated fatty acids. These characteristics increasingly emphasize the antioxidant enzyme Cu/Zn superoxide dismutase 1 (SOD1) to maintain neuronal redox homeostasis. In the last decade, SOD1 gained additional roles which are also important to the metabolism of neurons. SOD1 controls the production of ROS by the electron transport chain, activates the expression of genes involved in the protection against oxidative stress, and regulates the shift from oxidative to fermentative metabolism involved in astrocyte-neuron metabolic cooperation. Furthermore, impaired interaction between the phosphatase calcineurin and SOD1 seems to result in TDP-43 hyperphosphorylation, the main proteinopathy found in amyotrophic lateral sclerosis (ALS) patients. However, this enzyme is ubiquitously expressed, mutated, and damaged forms of SOD1 cause disease in motor neurons. In this review, we discuss the pivotal functions of SOD1 in neuronal biochemistry and their implications for ALS.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) are two neurodegenerative disorders that share common genes and pathomechanisms and are referred to as the ALS-FTD spectrum. A hallmark of ALS-FTD pathology is the abnormal aggregation of proteins, including Cu/Zn superoxide dismutase (SOD1), transactive response DNA-binding protein 43 (TDP-43), fused in sarcoma/translocated in liposarcoma (FUS/TLS), and dipeptide repeat proteins resulting from C9orf72 hexanucleotide expansions. Genetic mutations linked to ALS-FTD disrupt protein stability, phase separation, and interaction networks, promoting misfolding and insolubility. This review explores the molecular mechanisms underlying protein aggregation in ALS-FTD, with a particular focus on TDP-43, as it represents the main aggregated species inside pathological inclusions and can also aggregate in its wild-type form. Moreover, this review describes the protective mechanisms activated by the cells to prevent protein aggregation, including molecular chaperones and post-translational modifications (PTMs). Understanding these regulatory pathways could offer new insights into targeted interventions aimed at mitigating cell toxicity and restoring cellular function.},

abstract = {Protein functionality depends on its proper folding, making protein misfolding crucial for the function of proteins and, by extension, cells and the whole organism. Increasing evidence supports the role of protein misfolding in the pathogenesis of neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS). ALS is a rapidly progressive disease diagnosed at a prevalence of 5 cases per 100,000, with approximately 2-3 patients per 100,000 diagnosed each year. To date, there is no cure, and the disease usually leads to death within 2 to 5 years from diagnosis. There are two types of the disorder: familial ALS (fALS), accounting for approximately 10% of cases, and sporadic (sALS), accounting for the remaining 90%. The hallmark of ALS, regardless of type, is the protein aggregates found in patients' tissues. This suggests that the disruption of proteostasis plays a critical role in the development of the disease. Herein, we stress the distinct factors that lead to protein misfolding and aggregate formation in ALS. Specifically, we highlight several triggering factors affecting protein misfolding, namely mutations, errors in the processes of protein production and trafficking, and failures of folding and chaperone machinery. Gaining a deeper understanding of protein aggregation will improve our comprehension of disease pathogenesis and potentially uncover new therapeutic approaches.},

Irisin has been the subject of extensive research due to its potential as a metabolic regulator and its antioxidant properties. Notably, it has been associated with protective actions within the brain. Despite growing interest, many questions remain regarding the molecular mechanisms underlying its effects. This review summarizes recent findings on irisin, highlighting its pleiotropic functions and the biological processes and molecular cascades involved in its action, with a particular focus on the central nervous system. Irisin plays a crucial role in neuron survival, differentiation, growth, and development, while also promoting mitochondrial homeostasis, regulating apoptosis, and facilitating autophagy-processes essential for normal neuronal function. Emerging evidence suggests that irisin may improve conditions associated with non-communicable neurological diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, frontotemporal dementia, and multiple sclerosis. Given its diverse benefits, irisin holds promise as a novel therapeutic agent for preventing and treating neurological diseases.},

Studies with an odds ratio (OR) were included in the meta-analysis. A total of ten studies were included in this review, of which nine were suitable for meta-analysis from eight cohorts.

SWI is a 3D gradient-echo sequence with high spatial resolution that leverages both phase and magnitude effects. The interaction of paramagnetic (such as hemosiderin and deoxyhemoglobin), diamagnetic (including calcifications and minerals), and ferromagnetic substances with the local magnetic field distorts it, leading to signal changes. Neurodegenerative diseases are typically characterized by the progressive loss of neurons and their supporting cells within the neurovascular unit. This cellular decline is associated with a corresponding deterioration of both cognitive and motor abilities. Many neurodegenerative disorders are associated with increased iron accumulation or microhemorrhages in various brain regions, making SWI a valuable diagnostic tool in clinical practice. Suggestive SWI findings are known in Parkinson's disease, Lewy body dementia, atypical parkinsonian syndromes, multiple sclerosis, cerebral amyloid angiopathy, amyotrophic lateral sclerosis, hereditary ataxias, Huntington's disease, neurodegeneration with brain iron accumulation, and chronic traumatic encephalopathy. This review will assist radiologists in understanding the technical framework of SWI sequences for a correct interpretation of currently established MRI findings and for its potential future clinical applications.},

At this time, there are 17 variants of PCH distinguished by clinical presentation and distinctive radiological and biochemical features in addition to pontine and cerebellar hypoplasia. PCH1 is defined as PCH variant associated with anterior horn degeneration in the spinal cord with muscle weakness and hypotonia, and is associated with recessive variants in genes VRK1, EXOSC3, EXOSC8, EXOSC9 and SLC25A46. Neuromuscular manifestations may clinically present as amyotrophic lateral sclerosis (ALS), motor neuropathy (HMN) or neuronopathy (non-5q spinal muscular atrophy; SMA) or sensorimotor polyneuropathy (HMSN). Physiologic functions of PCH1-associated genes include regulation of RNA metabolism, mitochondrial fission and neuronal migration. Overall, complex phenotypes associated with PCH1 gene variants ranging from PCH and related neurodevelopmental disorders combined with neuromuscular disorders to isolated neuromuscular disorders have variable outcomes with isolated neuromuscular disorders typically having later onset with better outcomes. Improved understanding of pathogenesis of pontocerebellar hypoplasia and its association with motor neuronopathies and peripheral neuropathies may provide us with valuable insights and lead to potential new therapeutic targets for neurodegenerative disorders.},

They pose a significant and growing challenge due to their rising prevalence and impact on global health systems. The societal and emotional toll on patients, caregivers, and healthcare infrastructures is considerable. While significant progress has been made in elucidating the pathological hallmarks of these disorders, the underlying cellular and molecular mechanisms remain incompletely understood. Increasing evidence implicates oligodendrocytes and their progenitors-oligodendrocyte progenitor cells (OPCs)-in the pathogenesis of several NDs, beyond their traditionally recognized role in demyelinating conditions such as MS. Oligodendrocytes are essential for axonal myelination, metabolic support, and neural circuit modulation in the central nervous system. Disruptions in oligodendrocyte function and myelin integrity-manifesting as demyelination, hypomyelination, or dysmyelination-have been associated with disease progression in various neurodegenerative contexts. This review consolidates recent findings on the role of OPCs in NDs, explores the concept of myelin plasticity, and discusses therapeutic strategies targeting oligodendrocyte dysfunction. By highlighting emerging research in oligodendrocyte biology, this review aims to provide a short overview of its relevance to neurodegenerative disease progression and potential therapeutic advances.},

abstract = {The coronavirus disease 2019 (COVID-19) pandemic has been linked to long-term neurological effects with multifaceted complications of neurodegenerative diseases. Several studies have found that pathological changes in transactive response DNA-binding protein of 43 kDa (TDP-43) are involved in these cases. This review explores the causal interactions between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and TDP-43 from multiple perspectives. Some viral proteins of SARS-CoV-2 have been shown to induce pathological changes in TDP-43 through its cleavage, aggregation, and mislocalization. SARS-CoV-2 infection can cause liquid-liquid phase separation and stress granule formation, which accelerate the condensation of TDP-43, resulting in host RNA metabolism disruption. TDP-43 has been proposed to interact with SARS-CoV-2 RNA, though its role in viral replication remains to be fully elucidated. This interaction potentially facilitates viral replication, while viral-induced oxidative stress and protease activity accelerate TDP-43 pathology. Evidence from both clinical and experimental studies indicates that SARS-CoV-2 infection may contribute to long-term neurological sequelae, including amyotrophic lateral sclerosis-like and frontotemporal dementia-like features, as well as increased phosphorylated TDP-43 deposition in the central nervous system. Biomarker studies further support the link between TDP-43 dysregulation and neurological complications of long-term effects of COVID-19 (long COVID). In this review, we presented a novel integrative framework of TDP-43 pathology, bridging a gap between SARS-CoV-2 infection and mechanisms of neurodegeneration. These findings underscore the need for further research to clarify the TDP-43-related neurodegeneration underlying SARS-CoV-2 infection and to develop therapeutic strategies aimed at mitigating long-term neurological effects in patients with long COVID.},

abstract = {Senescence causes deterioration in the functioning and physiology of an organism. Microglia, the standing resident immune brain cells transform from neuroprotective to neurotoxic with age. Rapid process motility and cellular migration of microglia in the developing brain, and other characteristics are regarded to be crucial for immunological defense and tissue repair. As they mature, microglia not only differ in their morphology but also in their functioning. However, the exact mechanism related to the atrophies caused by aged microglia or their role in neurodegenerative diseases is still uncertain. The aim of this updated review is to provide insights of how aging microglial cells change and how this influences the development of neurodegenerative diseases. As life expectancy rises, there is an increase in the accumulation of iron, ROS/NOS, protein misfolding and insufficient clearing of debris. This is attributed to the age-dependent alterations in the genes linked to energy metabolism, mitochondrial and lysosome function, and neuroinflammation. Aging microglia often shifts towards a pro-inflammatory state with a reduction of anti-inflammatory cytokines. Aging microglia fail to clear amyloid-beta plaques, accelerates tau-pathology and enhances the chronic neuroinflammation, exacerbating the α-synuclein aggregation. These changes significantly impacted the onset of various neurogenerative disorders such as amyotrophic lateral sclerosis, Parkinson's disease, and Alzheimer's disease etc. However, it is important to note that these microglial aging effects might not be perceived as absolute, due to various limitations such as microglial heterogeneity, intercellular complexity across brain regions and variability in human aging owing to genetic and epigenetic variations. Regardless of this the future perspective of such insights are of immense relevance as novel therapeutic approaches can be formulated if the molecular and cellular mechanisms of aging microglial perturbations are understood. Future research should focus on restoring microglial homeostasis to mitigate the effects of aging on the brain and slowing the progression of neurodegenerative diseases.},

PNA5, a specific PNA variant, is highly expressed in neocortical association regions, particularly in primates, and plays a critical role in high-level cognitive functions such as reasoning, decision-making, and problem-solving. It can form stable, sequence-specific hybridizations with nucleic acids, resist nuclease degradation, and efficiently cross cellular membranes, making them ideal candidates for targeting disease-related genes in the brain. PNA5 has shown neuroprotective properties by improving cognitive function, reducing neuroinflammation, and preserving the integrity of the blood-brain barrier (BBB). Additionally, it supports critical processes such as neural migration, axon guidance, and synaptogenesis, which are vital for maintaining proper brain function. This review explores the mechanisms by which PNAs, particularly PNA5, exert therapeutic effects in neurological disorders. It highlights their role in gene modulation, protein regulation, and potential strategies for enhancing PNA delivery to the central nervous system (CNS) and its related disorders.},

As a genetically heterogeneous disease, ALS exhibits diverse inheritance patterns, including autosomal dominant, autosomal recessive, and X-linked transmission, and genetic factors play pivotal roles in disease pathogenesis. To date, at least 34 disease-causing loci and 32 genes for ALS have been identified. The investigations of mutant protein products and the establishment of animal models have unraveled potential pathogenic pathways, offering insights into the mechanisms of neurodegeneration in ALS. This review focuses on ALS clinical characteristics, neuropathological features, causative loci/genes, genetic susceptibility factors, animal models, and pathogenic mechanisms, with particular attention to recent advances in genetic findings and pathogenic pathways of ALS.

This computational capacity is expensive and requires a steady supply of energy and building blocks to operate. Importantly, the neural networks are composed of different cell populations, whose metabolic profiles differ between each other, thus endowing them with different metabolic capacities, such as, for example, the ability to synthesize specific metabolic precursors or variable proficiency to manage their metabolic waste. These marked differences likely prompted the emergence of diverse intercellular metabolic interactions, in which the shuttling and cycling of specific metabolites between brain cells allows the separation of workload and efficient control of energy demand and supply within the central nervous system. Nevertheless, our knowledge about brain bioenergetics and the specific metabolic adaptations of neural cells still warrants further studies. In this review, originated from the Fourth International Society for Neurochemistry (ISN) and Journal of Neurochemistry (JNC) Flagship School held in Schmerlenbach, Germany (2022), we describe and discuss the specific metabolic profiles of brain cells, the intercellular metabolic exchanges between these cells, and how these bioenergetic activities shape synaptic function and behavior. Furthermore, we discuss the potential role of faulty brain metabolic activity in the etiology and progression of Alzheimer's disease, Parkinson disease, and Amyotrophic lateral sclerosis. We foresee that a deeper understanding of neural networks metabolism will provide crucial insights into how higher-order brain functions emerge and reveal the roots of neuropathological conditions whose hallmarks include impaired brain metabolic function.},

We examine the role of physiologically derived androgens and androgenic supplements in neurodevelopment and neuroplasticity and delve into the involvement of androgen pathways in the pathogenesis of various neurological disorders.

RECENT FINDINGS: This review highlights the increasing recognition of testosterone and androgen signaling in various neurological conditions, with evidence of both protective and harmful effects depending on dosage and context. Although limited to experimental use, testosterone replacement therapy (TRT) may serve potential benefits in the management of multiple sclerosis, epilepsy, headache, Duchenne muscular dystrophy, amyotrophic lateral sclerosis, and Parkinson disease. On the other hand, androgen-blocking treatments may help alter disease progression in spinal and bulbar muscular atrophy. Testosterone supplementation can have potential adverse events when used at a supratherapeutic level, and prenatal testosterone exposure is believed to contribute to the pathogenesis of neurodevelopmental disease. Additionally, androgen-blocking agents could increase the risk of neurodegenerative conditions, such as Parkinson disease and Alzheimer disease. Despite the above findings, there is no established indication of TRT or androgen-blocking medication in neurological disorders. The body of evidence highlighting the involvement of androgens and androgen receptors (ARs) in pathogenesis of neurological diseases is growing. This includes ongoing research exploring the potential therapeutic targets involving the androgen signaling pathway for management of neurological disorders. Future placebo-controlled clinical trials are essential to determine the efficacy and safety of TRT or androgen-blocking therapies in managing neurological disease.},

abstract = {Current care and research pathways for amyotrophic lateral sclerosis (ALS) primarily rely on regularly scheduled visits to specialized centers. These visits provide intermittent clinical information to health care professionals and require patients to travel to the clinic. Digital health technologies enable continuous data collection directly from the patient's home, bringing new opportunities for personalized, timely care and a refined assessment of disease severity in clinical trials. In this review, we summarize the state of the art in digital health technologies for remote monitoring of patients with ALS, ranging from televisits through videoconferencing to sensor-based wearable devices. We explore how these technologies can benefit clinical care and advance treatment development. Despite significant progress, real-world adoption of these technologies remains limited. An overview is provided of the key barriers hindering their widespread implementation and the opportunities to advance the field. Significantly, there is an urgent need for harmonization across stakeholders through consensus guidelines and consortia. These efforts are essential to accelerate progress and harness the full potential of digital health technologies to better meet the needs of patients.},

This has generated significant research interest in the field. The proper functioning of mitochondria relies on the dynamic regulation of the mitochondrial quality control system. Key processes such as mitochondrial biogenesis, mitophagy, and mitochondrial dynamics (division/fusion) are essential for maintaining this balance. These processes collectively govern mitochondrial function and homeostasis. Therefore, the mitochondrial quality control system plays a critical role in the onset and progression of neurodegenerative diseases. This article provides a concise overview of the molecular mechanisms involved in mitochondrial biogenesis, mitophagy, and mitochondrial dynamics, explores their interactions, and summarizes current research progress in understanding the mitochondrial quality control system in the context of neurodegenerative diseases.},

This article explores the involvement of protein kinases in these disorders, focusing on their contributions to disease mechanisms, potential as therapeutic targets and challenges in developing effective treatments. In Alzheimer's disease, kinases such as CDK5, GSK3β and MARK4 are implicated in tau hyperphosphorylation and the formation of neurofibrillary tangles. Kinases also regulate amyloid-β processing and plaque formation. In Parkinson's disease, LRRK2, PINK1 and other kinases contribute to α-synuclein pathology, mitochondrial dysfunction and neuroinflammation. LRRK2 inhibitors and PROTACs have shown promise in preclinical models. Huntington's disease involves altered kinase activity, with CK2, GSK3 and MAPK pathways influencing mutant huntingtin toxicity and aggregation. Kinases are also implicated in less common neurodegenerative diseases, such as ALS and spinocerebellar ataxias. Despite the therapeutic potential of targeting kinases, challenges remain, including the complexity of kinase networks, blood-brain barrier permeability and the lack of robust biomarkers. Emerging technologies, such as covalent inhibitors, targeted protein degradation and combination therapies, offer new avenues for addressing these challenges and developing more effective treatments for neurodegenerative diseases.},

While Alzheimer's disease, Multiple Sclerosis, and Parkinson's disease have garnered considerable attention due to their incidence and socioeconomic significance, many additional neurological illnesses remain unclear in terms of underlying pathophysiology and prospective treatment targets. This review synthesizes evidence linking LPA's function in neurological diseases such as traumatic brain injury, spinal cord injury, cerebellar ataxia, cerebral ischemia, seizures, Huntington's disease, amyotrophic lateral sclerosis, Hutchinson-Gilford progeria syndrome, autism, migraine, and human immunodeficiency virus (HIV)-associated complications Despite recent advances, the specific mechanisms underlying LPA's actions in various neurological disorders remain unknown, and further research is needed to understand the distinct roles of LPA across multiple disease conditions, as well as to investigate the therapeutic potential of targeting LPA receptors in these pathologies. The purpose of this review is to highlight the multiple functions of LPA in the aforementioned neurological diseases, which frequently share the same poor prognosis due to a scarcity of truly effective therapies, while also evaluating the role of LPA, its receptors, and signaling as promising actors for the development of alternative therapeutic strategies to those proposed today.},

The manuscript investigates how Vitamin D3 impacts neuronal calcium regulation, antioxidative pathways, immunomodulation, and neuroprotection during detoxification, beyond its known functions in intestinal, bone, and kidney calcium and phosphorus absorption, as well as bone mineralization.

RECENT FINDINGS: Recent studies have highlighted the synthesis of the active metabolite 1,25(OH)2D3 (vitamin D) in glial cells via the hydroxylation process of CY-P24A1, an enzyme in the cytochrome P450 system in the brain. The effects of vitamin D occur through the vitamin D receptor (VDR), a nuclear steroid receptor, which has been identified in various brain regions, including the cerebellum, thalamus, hypothalamus, basal ganglia, hippocampus, olfactory system, temporal, and orbital regions. Neurodegeneration is primarily associated with oxidative stress, protein aggregation, neuroinflammation, mitochondrial dysfunction, apoptosis, and autophagy changes, all of which Vitamin D and VDR are believed to influence. Vitamin D and VDR are recognized as both environmental and genetic factors in the etiopathogenesis of neurodegenerative diseases such as Multiple Sclerosis (MS), Parkinson's Disease (PD), Alzheimer's Disease (AD), and Amyotrophic Lateral Sclerosis (ALS). A deficiency in Vitamin D is postulated to have detrimental effects on the brain and other diseases throughout various stages of life. This review consolidates findings from clinical and experimental studies, as well as past publications, focusing on the implications of Vitamin D deficiency in these neurodegenerative conditions. Current articles published in PubMed were extensively considered for this review.},

abstract = {Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are devastating neurodegenerative disorders with overlapping clinical, genetic and pathological features. A large body of evidence highlights the critical role of RNA-binding proteins (RBPs) - in particular TAR DNA-binding protein 43 (TDP-43) and Fused in sarcoma (FUS) - in the pathogenesis of these diseases. These RBPs normally regulate various key aspects of RNA metabolism in the nervous system (by assembling into transient biomolecular condensates), but undergo cytoplasmic mislocalization and pathological aggregation in ALS and FTD. Furthermore, emerging evidence suggests that RBP-containing aggregates may propagate through the nervous system in a prion-like manner, driving the progression of these neurodegenerative diseases. In this review, we summarize the genetic and neuropathological findings that establish RBP dysfunction as a central theme in ALS and FTD, and discuss the role of disease-associated RBPs in health and disease. Furthermore, we review emerging evidence regarding the prion-like properties of RBP pathology, and explore the downstream mechanisms that drive neurodegeneration. By unraveling the complex role of RBPs in ALS and FTD, we ultimately aim to provide insights into potential avenues for therapeutic intervention in these incurable disorders.},

METHODS: The CNKI, WOS, PubMed, and Scopus databases were searched by computer, and randomized controlled trials (RCTs) of exercise intervention in ALS were screened out according to the inclusion and exclusion criteria of the PICOS principle. Stata 12.0 software was used for statistical analysis.

RESULTS: A total of 12 RCTs including 430 participants were included. Meta-analysis results show that exercise intervention can significantly improve the overall function, walking test (WT) distance and maximum expiratory pressure (MEP) of ALS patients (p < 0.05). However, exercise interventions did not show significant effects on fatigue, maximum inspiratory pressure (MIP), forced vital capacity (FVC), and peak expiratory flow (PEF) in ALS patients (p > 0.05). Subgroup analysis showed that resistance exercise is the most effective intervention for improving the function of ALS patients, while aerobic exercise is the most effective intervention for improving FVC in ALS patients.

CONCLUSION: Exercise intervention in ALS has a positive effect, but due to the small number of included studies and possible heterogeneity, risk of bias and sensitivity issues, further research is needed.},

abstract = {BACKGROUND: Plantar fasciitis is a common sports injury with long-term chronic pain in the heel as the main symptom, and athletic taping has achieved certain therapeutic effects to improve it, but the clinical efficacy of the problem is still controversial, which was evaluated by Meta-analysis to evaluate the clinical efficacy of the athletic taping technique on patients with plantar fasciitis.

METHODS: The Cochrane Library, Embase, PubMed, Web of Science, CNKI, Wanfang, and Vip databases were searched by computer for randomized controlled trial on the clinical efficacy of exercise taping in patients with PF from the time of construction to 1 September 2024, and the PRISMA 2020 checklist was strictly followed. Quality was assessed using the cochrane 2.0 randomized controlled trials scale by two independent reviewers. Endings were meta-analysis using RevMan 5.4.1 analysis software to analyse the data.

RESULTS: Eleven randomized controlled trial with a total of 395 patients were included. On VAS scores, KT effectively reduced VAS pain scores (MD=-0.79,95 % CI -1.10,-0.48, P < 0.00001); on AOFAS scores, KT improved AOFAS function scores (MD=6.58, 95 % CI 5.03,8.13, P < 0.00001) and the results remained consistent across intervention durations; on plantar fascia thickness measurements, KT significantly reduced plantar fascia thickness (MD=-0.33, 95 % CI -0.56,-0.10, P = 0.005); on BBS scores, KT significantly improved BBS scores [MD= 4.75, 95 % CI (3.17, 6.32), P < 0.00001]; on FFI-FPS scores, KT effectively improved FFI-FPS scores [MD = -2.59, 95 % CI (-3.50, -1.69), P < 0.00001]; on FFI-FDS scores, there was a significant improvement on FFI-FDS scores; on FFI-ALS scores, KT had a significant improvement on the FFI-ALS score had a significant effect [MD= -11.03, 95 % CI (-14.79, -7.27), P < 0.00001]; and on VAS scores after follow-up, the pain relief effect was sustained (MD=-1.03, 95 % CI -1.21, -0.85, P < 0.00001).

CONCLUSION: Based on the available evidence, preliminary analyses suggest that KT combined with conventional rehabilitation may have some advantages in improving pain, ankle-hindfoot function, and plantar fascia thickness in patients with plantar fasciitis, and some of the efficacy is short-term sustained. However, due to the heterogeneity and sample size of the included studies, the above conclusions need to be further validated by more high-quality studies.},

Recent findings indicate that the activation of the NLRP3 inflammasome in microglia and astrocytes triggers the release of pro-inflammatory cytokines, including IL-1β and IL-18, which contribute to chronic inflammation and neuronal damage. This process accelerates neurodegeneration and exacerbates disease progression. Misfolded protein aggregates, mitochondrial dysfunction, and oxidative stress are key factors in the pathological activation of the NLRP3 inflammasome in these diseases. Recent studies have highlighted that targeting the NLRP3 inflammasome, either through direct inhibitors like MCC950 or natural compounds such as oridonin and β-hydroxybutyrate, shows promise in mitigating neuroinflammation and protecting neuronal integrity. These inhibitors have demonstrated neuroprotective effects in animal models of AD, PD, and MS, presenting a new therapeutic approach for halting disease progression. However, the complexity of NLRP3 regulation requires further investigation to balance its inflammatory and protective roles. This review examines the recent advancements in NLRP3 inflammasome research and discusses potential strategies for modulating inflammasome activity to slow or prevent the progression of neurodegenerative diseases.},

abstract = {Neuroinflammation is caused by various factors, such as the activation of glial cells, the excessive release of chemokines and cytokines, and the accumulation of blood cells in the brain parenchyma. The inflammatory processes occur in acute and chronic phases, with traumatic brain injuries triggering the release of neurotoxins from CNS-specific glial cells. Furthermore, activation of microglia, astrocytes, and mast cells worsens the situation by producing pro-inflammatory cytokines, chemokines and glia maturation factors. Chronic activation of astroglia and microglial cells promotes loss of neurons, memory, and impaired learning capacity, leading to neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis. These implications have led to a rational search for inflammatory druggable targets. Based on various preclinical and clinical studies, NSAIDs (aspirin, ibuprofen, diclofenac, and mefenamic acid), SSRIs (fluoxetine and sertraline), antipsychotics (risperidone), corticosteroids (dexamethasone), antidiabetics (metformin and rosiglitazone), and statins (simvastatin and atorvastatin) have exhibited promising results. These drugs have anti-inflammatory and neuromodulation activities that enhance neuroplasticity and effectively manage neurodegenerative symptoms. In addition, non-pharmacological interventions such as art creation and physical exercise have been linked with improving neural development and stimulating the production of anti-inflammatory cytokines, which can attenuate disease progression and promote synaptic plasticity. Hence, it is imperative to understand the complex interplay between glial cells, inflammatory signalling and neural pathways. We reviewed the interconnected pathways between neuroinflammation and neurodegeneration. Moreover, recommendations for pharmacological and non-pharmacological interventions to address these issues are discussed herein.},

Intractable diseases are more common but often involve complex mechanisms, treatment with limited efficacy, and high medical costs, placing a heavy burden on patients and healthcare systems. In recent years, traditional Chinese medicine (TCM) has demonstrated unique advantages in the treatment of intractable and rare diseases and has gradually become an important complementary treatment. The current work is a systematic review of the progress of clinical and experimental research on TCM in typical rare diseases such as amyotrophic lateral sclerosis (ALS), systemic lupus erythematosus (SLE), mitochondrial encephalomyopathy, aplastic anemia (AA), and Wilson's disease (WD). It focuses on the multi-target therapeutic mechanisms of key Chinese herbal compound formulas, including immune regulation, antioxidative stress, and neuroprotection. The core TCM theories of "syndrome differentiation", "different treatments for the same disease" and the "same treatment for different diseases" are also discussed in the context of personalized medicine. In recent years, China has continuously promoted the development of TCM through a series of national plans and supportive policies, such as the 14th Five-Year Plan for TCM development, funding for key special projects, expedited approval pathways, and expanded coverage by medical insurance. These efforts have provided strong support for the clinical translation of TCM and technological innovation in the field of intractable and rare diseases. Notwithstanding the encouraging advances, the field of Chinese medicine continues to grapple with numerous challenges. In the future, the enhancement of mechanistic studies and quality multicenter clinical trials needs to be promoted while further enhancing policy support and international collaboration to substantiate the scientific basis and clinical value of TCM in the prevention and treatment of intractable and rare diseases.},

abstract = {BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons, resulting in muscle weakness, loss of function, and ultimately death due to respiratory failure. Due to the lethal prognosis of ALS, respiratory muscle training has been proposed as a potentially beneficial intervention.

OBJECTIVES: To systematically review the efficacy of respiratory muscle training on lung function and respiratory muscle strength in ALS patients.

DESIGN: A systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES AND METHODS: Articles published in PubMed, PEDro, Scopus, and Web of Science databases up to July 2024. The Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 statement guideline was followed. Included studies had (1) ALS patients, (2) respiratory muscle training, (3) physical exercise, usual care or no intervention were provided as a comparison group, (4) assessments of lung function, respiratory muscle strength, quality of life, survival, fatigue, and functional capacity outcome measures, and (5) a randomized controlled trial design. Methodological quality was analyzed using the PEDro scale, and risk of bias with the Cochrane Collaboration Risk of Bias Tool. Meta-analyses were performed with Review Manager software.

RESULTS: Five randomized controlled trials with 170 participants were included. The results showed that respiratory muscle training improved muscle strength, particularly maximum expiratory and inspiratory pressures. One study suggested inspiratory muscle training as a survival predictor in ALS patients. No significant effects were observed in forced vital capacity or quality of life. No adverse effects were reported.

CONCLUSION: Respiratory muscle training improves ventilatory function, particularly respiratory muscle strength, in people with ALS. While evidence is limited, it shows promise as an adjuvant therapy to enhance quality of life and survival. It has been registered in the PROSPERO (CRD42024568235).},

abstract = {L-DOPA remains a cornerstone treatment for Parkinson's disease and is increasingly recognized for its role in various neurological and neurodegenerative disorders. As a direct precursor to dopamine, L-DOPA is synthesized from L-tyrosine through the action of tyrosine hydroxylase and is subsequently converted into dopamine via aromatic L-amino acid decarboxylase. Its ability to cross the blood-brain barrier (BBB) makes it a crucial therapeutic agent for restoring dopaminergic neurotransmission, thereby influencing motor function, cognition, and neuroprotection. Beyond Parkinson's, L-DOPA's therapeutic potential extends to neurodegenerative conditions such as Alzheimer's disease, Huntington's disease, multiple sclerosis, Lewy body dementia, and amyotrophic lateral sclerosis, where dopamine modulation plays a critical role. Furthermore, L-DOPA has demonstrated efficacy in neurological disorders including epilepsy, peripheral neuropathy, cerebrovascular diseases, and traumatic brain injury, suggesting broader neurobiological applications. However, long-term use is associated with challenges such as motor fluctuations, dyskinesias, and loss of therapeutic efficacy due to progressive neurodegeneration and alterations in dopaminergic pathways. Recent advancements in drug delivery systems, combination therapies, and nanotechnology, including plant-derived carbon dots, offer promising strategies to enhance L-DOPA's effectiveness while mitigating its limitations. This comprehensive review explores L-DOPA's synthesis, pharmacokinetics, mechanism of action, and its evolving role in neurological diseases, while highlighting ongoing challenges and future directions for optimizing its clinical application.},

abstract = {Receptor-interacting protein kinase 1 (RIPK1)-mediated necroptosis, a newly identified mode of regulated cell death, represents a significant pathogenic mechanism in multiple neurodegenerative disorders. Substantial experimental evidence indicates that RIPK1 regulates necroptotic cell death pathways in both neuronal and glial cell populations through activation of the canonical RIPK3-MLKL signaling cascade, thereby exacerbating neuroinflammatory responses and accelerating neurodegenerative progression. The pathological relevance of this molecular pathway has been extensively validated across multiple major neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS). Pharmacological interventions targeting RIPK1 or its downstream effectors-particularly RIPK3 and MLKL-have demonstrated significant efficacy in mitigating disease-associated pathological manifestations. This highlights the RIPK1 signaling axis as a promising therapeutic target for neuroprotective strategies. Consequently, thorough investigation of RIPK1-mediated necroptosis in neurodegenerative settings holds considerable translational potential. Such inquiry deepens mechanistic understanding of disease pathogenesis while accelerating the advancement of innovative therapeutic approaches with direct clinical relevance.},

abstract = {BACKGROUND: Movement-based therapists, including physical, exercise, and sport therapists, play a key role in promoting physical activity in individuals with non-communicable diseases. However, no clear consensus exists on effective intervention approaches. This scoping review examines available intervention studies and theoretical works for physical activity promotion in movement-based therapy. METHODS: In accordance with Colquhoun et al.‘s framework and PRISMA-ScR guidelines, we systematically searched PubMed, Scopus, Web of Science, and PsycINFO until March 31, 2024. Eligible records described physical activity-promoting concepts including interventional studies and theoretical works applicable in movement-based therapies for individuals with non-communicable diseases. Data extraction covered assessment, therapeutic content, didactic-methodological principles, and theoretical underpinnings. Interventions were categorized based on behavior change techniques (BCTs), the behavior change wheel, and a clinical reasoning model for clients behavior change. Network analysis explored relationships between therapeutic content and didactic-methodological principles. RESULTS: Fifty-seven records met inclusion criteria; 77% were intervention studies, and 23% were theoretical works. Most concepts originated from orthopedics/rheumatology (23%), neurology (21%), and oncology (9%), while 12% were generic concepts. Across concepts, 66 biopsychosocial assessment instruments and 60 BCTs were applied (Median BCTs per concept: 11.5, range: 4–37). Key didactic-methodological principles included tailoring/individualization (n = 47), active participation (n = 39), collaborative communication (n = 21), and patient self-responsibility and independence (n = 14). Least mentioned was facilitating positive movement experiences and enjoyment of physical activity (n = 3). Network analysis identified action planning, goal setting, and feedback as central BCTs. CONCLUSION: This review provides an overview of 57 physical activity promotion concepts used in movement-based therapies for individuals with non-communicable diseases. Findings reveal considerable heterogeneity, highlighting diverse strategies used by movement-based therapists to influence physical activity behavior.

Classical homocystinuria (HCU), an inborn error of sulfur amino acid metabolism, results from cystathionine beta-synthase (CBS) deficiency. CBS regulates methionine conversion into metabolites critical for redox balance (cysteine, glutathione) and signaling (H2S). Pathogenic missense mutations in the CBS gene often impair folding, cofactor binding, stability or oligomerization rather than targeting the key catalytic residues of the CBS enzyme. Advances in understanding of CBS folding and assembly as well as CBS interactions with cellular proteostasis network offer potential for therapies using pharmacological chaperones (PCs), i.e., compounds facilitating proper folding, assembly or cellular trafficking. This review discusses progress in identifying PCs for HCU, including chemical chaperones, cofactors, and proteasome inhibitors. We outline future directions, focusing on high-throughput screening and structure-based drug design to develop CBS-specific PCs. These could stabilize mutant CBS, enhance its stability and restore activity, providing new treatments for HCU and possibly other conditions related to dysregulated CBS, such as cancer or Down's syndrome.},

Despite efforts to carefully define and stratify ALS patients according to their clinical and genetic features, prognosis prediction still remains unreliable. Biomarkers that reflect changes in the central nervous system would be useful, but the physical impossibility of direct sampling and analysis of the nervous system makes them challenging to validate. A highly explored option is the identification of neuronal-specific markers that could be analyzed in peripheral biofluids. This review focuses on the description of the physical and biological barriers to the central nervous system and of the composition of biofluids in which ALS disease biomarkers are actively searched. Finally, we comment on already validated biomarkers, such as the neurofilament light chain, and show the potential of extracellular vesicles (EVs) and cell-free DNA as additional biomarkers for disease prediction.},

Compared to other glial cells, the oligodendroglial lineage is highly vulnerable to ageing and undergoes significant characteristic changes that impact upon its structure and impair its physiological functions. Therefore, the ageing and degeneration of oligodendroglia become major risk factors for neurodegenerative diseases. During the age-related disease process, changes in oligodendroglia lead to a decline in their ability to regenerate myelin and respond to the aged microenvironment, which are closely linked to the pathogenesis of neurodegenerative diseases, facilitating the emergence of these diseases in older populations. In this chapter, we introduce the physiological changes of oligodendroglia during ageing and the related mechanisms and then summarise their pathophysiological contributions to age-related cognitive disorders. Finally, we discuss potential therapeutic strategies that target oligodendroglia for future research on neurodegenerative diseases.},

abstract = {BACKGROUND: People with a rare disease find it difficult to obtain a diagnosis and access appropriate services. Evidence suggests that this can lead to health inequity amongst the rare disease community, i.e. systemic, unfair and avoidable differences in health opportunities and outcomes. This scoping review aims to identify and describe evidence on health inequities experienced by the rare disease community with regards to receipt of a diagnosis and access to health and social care services.

METHODS: We searched ASSIA, CINAHL, Embase, HMIC, MEDLINE and Social Policy and Practice for relevant studies. Studies were double screened at title and abstract and full-text using pre-specified inclusion criteria. As this research was commissioned by the UK National Institute for Health and Care Research Policy Research Programme, primary studies were limited to UK settings. These were supplemented with international systematic reviews. We also applied a 2010 date limit. Relevant data were extracted and presented narratively and tabulated.

RESULTS: One hundred thirty-six studies met the inclusion criteria, including 96 primary studies and 40 systematic reviews. The most frequently occurring rare diseases were motor neurone disease, cystic fibrosis and sickle cell disease. Seventeen types of inequity were identified: delayed diagnosis, lack of knowledge amongst clinicians, lack of information provision, limited services provision (across six different services), limited services for undiagnosed conditions, lack of care co-ordination; in addition, inequity was identified relating to place of residence, race/ethnicity, gender, socioeconomic status, age and disability.

CONCLUSION: This review has drawn attention to experiences of the rare disease community with respect to receipt of a diagnosis and access to services which are different to experiences in the general population, and within the rare disease community itself. Some of these experiences are clearly attributable to factors which are unfair, avoidable and systemic, particularly those which relate to specific groups in the rare disease community. Experiences relating to delayed diagnosis, lack of knowledge, information, care co-ordination and access to various services, also appeared to indicate inequity. These issues are less likely to be encountered with respect to more common diseases experienced in the general population.},

This form of cell death plays an important role in various neurodegenerative diseases of the central nervous system, such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and stroke.

Age and stage in the life course influence how illness is experienced; however, the extent to which age-specific complexities of living with ALS have been examined remains unexplored. This review aims to map the available evidence exploring age, age-graded role, or life-course transition with regards to the experience of ALS and to identify age-specific gaps in the literature. Methods: A scoping review guided by Joanna Briggs Institute methodology was undertaken. Eligible articles included peer-reviewed primary research studies, published in English from 2010 onward, investigating illness experience of adults with ALS with consideration for how age, age-graded roles, or life-course transitions influenced experience. Database sources included: Ovid's Medline, Embase, and PsycINFO; EBSCO CINAHL; and ProQuest Sociological Abstracts. Findings related to ALS experience and dimensions of age were summarized descriptively and categorized using qualitative content analysis. Results: Six thousand one hundred and eighty individual records were identified and screened. Forty-five articles, reporting 42 studies, were included. Findings regarding thoughts, feelings, or emotions of plwALS were most common and varied depending on whether they were in reference to chronological age or age-graded role. Despite the importance of life-course transitions for illness experience, they were not routinely considered. Conclusion: Numerous aspects of the experience of plwALS have been reported in reference to age; however, the significance of age-graded roles and life-course transitions warrants further examination. Recognition of age-related complexities of living with ALS will facilitate more personalized ALS care.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease of multifaceted nature and variable progression that poses considerable challenges to our understanding of its evolution and interplay with different comorbid conditions. The etiopathogenesis of ALS is still unexplained and multimorbidity is common, but its influence on the ALS susceptibility and disease course is a matter of discussion. This study using medical databases tries to find diseases associated with ALS and their impact on disease onset and progression. Diseases associated with the risk of ALS include diabetes mellitus, dyslipidemias and cardiovascular comorbidities that may play an important role in the prognosis of ALS. Hypometabolic disorders and cardiovascular diseases may have a protective effect on ALS incidence, while coronary heart disease and hypertension have a negative effect on disease progression. Other comorbidities include Parkinson disease, TDP-43 pathology, progressive supranuclear palsy, progressive aphasia, myasthenia gravis, cancer and autoimmune disorders, while there is no evidence for a shared genetic background of common risk variants in ALS and multiple sclerosis. Among non-motor manifestations of ALS, cognitive and behavioral impairments are important. Other comorbidities include sleep disorders, traumatic encephalopathy, sarcoidosis, prionopathies, schizophrenia, cervical spondylotic myelopathy, psoriasis and others. The tremendous heterogeneity of concomitant pathologies and comorbidities observed across the ALS spectrum may be caused by a complex interplay between genetic, pathogenetic, inflammatory and other risk factors that are still poorly understood. Further research should provide increasing insight into their relationship with motor system disorders in order to find better diagnostic tools and probable effective therapies for these disease-modifying comorbidities.},

This review investigates contemporary advancements in alginate-based nanoformulations, with a particular emphasis on their efficacy in surmounting obstacles to successful pharmacological delivery to the brain. Initially, we furnish a comprehensive overview of alginate, underscoring its pertinent properties, biomedical applications, and inherent limitations. Subsequently, the discourse progresses to strategies for nanoformulation, which encompass lipid-based, polymeric, and inorganic methodologies, with a focus on their benefits in relation to cerebral targeting. Moreover, this review entails the therapeutic potential of alginate-based nanoformulations in addressing significant neurological disorders, including Alzheimer's disease, Parkinson's disease, brain tumours, traumatic brain injury, epilepsy, and amyotrophic lateral sclerosis. By amalgamating cutting-edge nanotechnology with the distinctive properties of alginate, these formulations signify a promising pathway for the advancement of efficacious therapies aimed at brain targeting. Additionally, prospective research trajectories and challenges associated with the optimization of alginate-based nanocarriers for clinical applications are also elucidated.},

abstract = {INTRODUCTION: Emotional contagion (EC) involves the automatic mimicry and synchronization of expressions, vocalizations, and movements, resulting in emotional alignment between individuals. Despite consistent scholastic explorations of the various nuances and tenets associated with emotional contagion processes and outcomes, there has yet to be a thorough review of human subjects-based emotional contagion research.

METHODS: This review examines human subjects EC research trends, analyzing 277 articles (published from 1992 to 2022) to identify common conceptualizations, triggers, and measurement methods.

RESULTS: Analyses indicated that Hatfield et al.'s classic conceptualization is the most cited, and common triggers include facial expressions in images and videos, and real-time interactions - though many studies did not stimulate EC. While many studies did utilize validated EC scales, about 28% of the studies reviewed used non-validated questions to measure EC. Moreover, the EC research reviewed heavily relies on college-aged, predominantly white participants, indicating a need for more diverse samples.

DISCUSSION: Future EC research should explore processes and nuances associated with EC among older adults, minoritized groups, and diverse contexts (e.g., healthcare, schools), using novel triggers and multiple measurement methods.},

abstract = {Non-neuronal glial cells in the brain, such as astrocytes, play essential roles in maintaining the functional integrity of neuronal cells. A growing body of evidence suggests that cellular senescence of astrocytes, characterized by loss of proliferative potential and secretion of neurotoxic cytokines, makes significant contribution to neurotoxicity in Alzheimer's disease and a wide range of other neurodegenerative diseases. This review discusses the beneficial effects of Δ133p53α, a natural p53 protein isoform that inhibits p53-mediated cellular senescence, thereby protecting astrocytes from senescence, highlights its potential as a therapeutic target, and underscores the need for continued research in this area. Both in senescent human astrocytes in culture, whether induced by replicative exhaustion, irradiation or exposure to amyloid-β, and in brain tissues with increased senescent astrocytes from patients with Alzheimer's disease, the expression levels of endogenous Δ133p53α protein were consistently and significantly reduced. The lentiviral vector-driven expression of Δ133p53α protected cultured human astrocytes from cellular senescence and neurotoxic secretory phenotype, leading to their cellular reprogramming to a neuroprotective state associated with neurotrophic growth factors. We thus propose that Δ133p53α is worth testing as a therapeutic target that can be enhanced in a wide range of neurodegenerative diseases with accumulated senescent astrocytes, including Alzheimer's disease, amyotrophic lateral sclerosis, Parkinson's disease, and chronic traumatic encephalopathy due to traumatic brain injury. We hypothesize that a Δ133p53α-mediated cellular reprogramming approach and a senolytic or senomorphic approach, both targeting non-neuronal cells, may be complementary with each other, and may cooperate with neuron-protecting or amyloid-β-targeting therapies currently in use.},

KIF5A mediates a wide range of trafficking processes that are only partially shared with the other members of the KIF5 family. Since 2002, several disease-causing mutations have been found in the KIF5A gene and a link between the specific domain in the encoded protein affected by mutations and the associated phenotype has become evident. Point mutations targeting KIF5A motor and stalk domains, that are expected to impair KIF5A motility, mainly associate with spastic paraplegia type 10 (SPG10) and axonal Charcot-Marie-Tooth (CMT) disease. Oppositely, translational frameshifts causing the elongation of KIF5A tail enhance KIF5A migration towards cell periphery, induce kinesin aggregation, and are linked to amyotrophic lateral sclerosis (ALS) or neonatal intractable myoclonus (NEIMY). This review correlates KIF5A structure and roles in neuronal trafficking with its involvement in the above-mentioned neurodegenerative and neurodevelopmental conditions.},

Recent studies have highlighted its significant impact on neurodegenerative diseases, conditions that pose profound challenges to affected individuals and society at large. This review explores the intricate relationship between gut microbiota and the progression of neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and Amyotrophic Lateral Sclerosis. We delve into the dynamic ecosystem of gut microbiota, examining factors influencing its composition and the bidirectional communication established via the gut-brain axis. Emerging evidence suggests that gut microbiota can modulate neurodegenerative disease progression through mechanisms including inflammatory responses, production of neuroactive substances, and regulation of neurotransmitters. Furthermore, we discuss the potential therapeutic implications of targeting gut microbiota with probiotics, prebiotics, and postbiotics. While promising, these interventions face challenges and limitations that must be addressed through ongoing research. Understanding the role of gut microbiota in neurodegenerative diseases is crucial for developing innovative therapeutic strategies and improving patient outcomes.},

abstract = {OBJECTIVE/HYPOTHESIS: The vast majority of the global population speaks more than one language. In the United States, Spanish-English bilingual speakers are the largest bilingual group. Yet, the potential effect of being bilingual, specifically a Spanish-English speaker, on voice quality is poorly understood. The current study consequently set out to systematically review the literature on the association between being a Spanish-English bilingual speaker and voice quality.

STUDY DESIGN: Systematic review.

METHODS: A systematic review of association was conducted using Moola et al's guidelines. A search string was developed and run in May 2024 across three databases: MEDLINE (via PubMed), CINAHL via EBSCOhost, and Scopus. After duplicate removal, title, and abstract screening, full-text screening was performed, and peer-reviewed articles considering voice quality measures in Spanish-English bilingual speakers were included. Data were extracted and presented in table format, and the quality of the articles was assessed using the Checklist for Analytical Cross-Sectional Studies.

RESULTS: In total, 685 records were retrieved, with 485 remaining after duplicate removal. After title and abstract screening, 25 full texts were screened, including 8 articles in the review. Five studies included acoustic measures describing voice quality, with only three including auditory-perceptual analysis. The most commonly considered vocal trait in Spanish-English bilinguals was vocal fry, with the included studies pointing to increased vocal fry use when speaking English.

CONCLUSIONS: Only a few articles discuss potential vocal changes in Spanish-English bilinguals. Further research is needed to elucidate any potential vocal changes related to being a bilingual speaker, as the current small number of studies and mixed findings make drawing conclusions difficult. More standardization across voice and language assessment could be beneficial.},

abstract = {Neurological disorders, including neurodegenerative diseases, traumatic brain injuries (TBI), and central nervous system (CNS) tumors, are complex conditions that significantly impact patients globally. Timely diagnosis and monitoring are critical for improving outcomes, driving the need for reliable biomarkers. Specifically, biomarkers detectable in cerebrospinal fluid (CSF) and blood offer important insights into disease presence and progression. This review explores the evolution of circulating blood biomarkers for neurodegenerative diseases, TBI, and CNS tumors, highlighting advanced detection technologies from enzyme-linked immunosorbent assays (ELISAs) to electrochemiluminescence (ECL) assays, single-molecule arrays (Simoa), and mass spectrometry. Advanced technologies with enhanced sensitivity and specificity, particularly in detecting low-abundance analytes, facilitate the investigation of CSF biomarkers for various neurological disorders. We also describe the progress in blood-based biomarkers for , emerging as less invasive alternatives to CSF sampling. Clinically, the implementation of Alzheimer's disease (AD) blood biomarkers Aβ42/Aβ40 ratio and Apolipoprotein E isoform-specific peptide can aid the diagnosis, while p-tau181 and p-tau217 differentiates AD dementia from non-AD neurodegenerative diseases. Blood glial fibrillary acidic protein and ubiquitin C-terminal hydrolase-L1 are used in ruling out mild TBI. Despite these innovations, challenges remain, including assay standardization, sensitivity/specificity trade-offs, and the requirement for longitudinal studies to understand biomarker utility over time. Future research should focus on addressing these challenges to fully realize the potential of blood-based biomarkers in neurological disorder diagnostics and patient care.},

In 2022, China's alumina production totaled 77.475 million tonnes, contributing over 4 billion tonnes of accumulated red mud, which is the third-largest industrial solid waste in the country. Red mud's high alkalinity and presence of toxic elements pose environmental challenges, particularly in terms of disposal. This review provides a comprehensive examination of red mud-based cementitious materials, focusing on their preparation, properties, and environmental impact. By combining red mud with high-calcium and silica-aluminum solid wastes and enhancing its reactivity through mechanical grinding or thermal activation, red mud's cementitious activity can be significantly improved. Optimized compositions, with a Ca/Si ratio of 2.05 and Al/S ratio of 0.70, have achieved compressive strengths of up to 63.9 MPa at 28 day. Durability studies highlight the material's resistance to chloride ion penetration and sulfate attack, with reduced permeability enhancing long-term performance. Additionally, environmental assessments confirm that stabilization and solidification techniques effectively mitigate heavy metal leaching, ensuring compliance with EPA standards. Despite these advancements, challenges remain in optimizing red mud activation processes, improving rheological properties, and reducing production costs. Future research should focus on refining activation methods, enhancing hydration mechanisms, and developing scalable industrial applications. By addressing these gaps, red mud-based cementitious materials can become a sustainable solution for eco-friendly construction, supporting global efforts to repurpose industrial byproducts into low-carbon, durable building materials.},

RNA therapeutics encompass diverse molecules like antisense oligonucleotides (ASOs), small interfering RNAs (siRNAs), microRNAs (miRNAs), RNA aptamers, and messenger RNAs (mRNAs), which can function through different mechanisms. RNA therapeutics are increasingly used to treat various diseases, including neurological disorders. For example, ASO therapies such as nusinersen for spinal muscular atrophy and eteplirsen for Duchenne muscular dystrophy are successful applications of RNA-based treatment. Emerging ASO treatments for Huntington's disease and amyotrophic lateral sclerosis are also promising, with ongoing clinical trials demonstrating significant reductions in disease-associated proteins. Still, delivery of these molecules remains a pivotal challenge in RNA therapeutics, especially for ASOs in penetrating the blood-brain barrier to target neurological disorders effectively. Nanoparticle-based formulations have emerged as leading strategies to enhance RNA stability, reduce immunogenicity, and improve cellular uptake. Despite these advances, significant hurdles remain, including optimizing pharmacokinetics, minimizing off-target effects, and ensuring sustained therapeutic efficacy. Regulatory frameworks are evolving to accommodate the unique challenges of RNA-based therapies, including ASOs with efforts underway to establish comprehensive guidelines for RNA therapeutics, yet there are also sustainable manufacturing issues that need to be considered for long-term feasibility. By addressing these challenges, RNA therapeutics hold immense potential to revolutionize treatment paradigms for neurological disorders. Looking forward, the future of RNA therapeutics in neurology appears promising but requires continued interdisciplinary collaboration and technological innovation.},

abstract = {BACKGROUND: Alternative splicing (AS) plays a crucial role in regulating gene expression and governing proteomic diversity by generating multiple protein isoforms from a single gene. Increasing evidence has highlighted the regulation for pre-mRNA splicing of the splicing factors (SFs). This review aims to examine featured mechanisms and examples of SF regulation by AS, focusing on paradigmatic feedback loops and their biological implications.

MAIN BODY OF THE ABSTRACT: We specifically focus on the autoregulation and inter-regulation of SFs through AS machinery. These interactions give rise to a feedback system, where the negative feedback loops aid in maintaining cellular homeostasis, and the positive feedback loops play roles in triggering cellular state transitions. We examine the growing evidence highlighting the specific mechanisms employed by SFs to autoregulate their own splicing, including AS-coupled nonsense-mediated mRNA decay (AS-NMD), nuclear retention, and alternative 3'UTR regulation. We showcase the influence of AS feedback in amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and cancer. Furthermore, we discuss how master splicing factors can dominantly orchestrate splicing cascades, leading to widespread impacts in cellular processes. We also discuss how non-coding RNAs, particularly circular RNAs and microRNAs, engage in the splicing regulatory networks. Lastly, we showcase how negative and positive feedback loops can collaboratively achieve remarkable biological functions during the cell fate decision.

SHORT CONCLUSION: This review highlights the regulation of SFs by AS, providing enriched information for future investigations that aim at deciphering the intricate interplay within splicing regulatory networks.

KEY POINTS: Negative feedback of alternative splicing maintains cellular homeostasis. Positive feedback of alternative splicing triggers cellular state transitions. Alternative splicing forms integrated feedback networks with circRNAs and microRNAs to reciprocally regulate their expression and function. The coordinated interplay of distinct splicing feedback mechanisms orchestrates precise cell fate transitions. Future directions and therapeutic possibilities that could transform alternative splicing research into treatments.},

Researchers have stressed the importance of integrating critical pedagogies, such as antiracist pedagogy, to help learners understand societal and structural factors behind health inequities and recognize power dynamics in health science and healthcare. Various antiracist pedagogical interventions have been designed, but their outcomes remain unclear. Based on Levac et al.'s framework, a scoping review was conducted to map the literature evaluating the outcomes of antiracist pedagogy in health professions education. A systematic database search was conducted between April and June 2022 for articles describing evaluation methods and outcomes of antiracist pedagogical interventions in health professions education. We included 41 articles in the final selection. The data was organized within the following themes: aim of intervention, type of intervention, evaluation tools, outcomes and indicators for each of Kirkpatrick's levels of training evaluation, theoretical frameworks, and authors' positionalities. The thematic analysis revealed that, in most cases, evaluations targeted participants' attitudes on systemic racism, their racial identity and critical awareness, as well as their satisfaction with the activities. The antiracist pedagogical interventions were rarely evaluated beyond learners' perceptions. Discrepancies were also raised between the principles of antiracist education and the use of antiracist pedagogy to design, implement and evaluate the outcomes of antiracist pedagogical interventions in health professions education. Although only a few interventions had transformative outcomes beyond individuals, we identified promising pedagogical strategies to foster engagement and motivation to transform professional practices.},

abstract = {This paper explores the therapeutic potential of DMT in neuroprotective strategies, particularly concerning ischemia-reperfusion injury (IRI) and neurodegenerative disorders. Besides its potent serotonin receptor actions, DMT is also an endogenous agonist of the sigma-1 receptor (Sig-1R). Sigma receptors are a unique family of proteins with high expression in the brain and spinal cord and have been involved in the etiology, symptom course and treatment of several central nervous system disorders. Our previous theoretical and experimental work strongly suggest that targeting sigma (and serotonin) receptors via DMT may be particularly useful for treatment in a number of neurological conditions like stroke, global brain ischemia, Alzheimer's disease, and amyotrophic lateral sclerosis. In this article, we briefly overview the function of Sig1-R in cellular bioenergetics with a focus on the processes involved in IRI and summarize the results of our previous preclinical (in vitro and in vivo) DMT studies aiming at mitigating IRI and related cellular neuropathologies. We conclude that the effect of DMT may involve a universal role in cellular protective mechanisms suggesting therapeutic potentials against different components and types of IRIs emerging in local and generalized brain ischemia after stroke or cardiac arrest. The multiple neuroprotective mechanisms facilitated by DMT may position it as a model molecule for developing pharmacological treatments for neurodegenerative disorders.},

abstract = {BACKGROUND: Pharmacists are uniquely positioned to address substance use disorders (SUDs) and expand harm reduction services due to their accessibility and expertise in medication management. However, attitudinal and structural barriers may limit their full potential in this role.

OBJECTIVE: This scoping review examines pharmacists' knowledge, attitudes, and engagement in SUD treatment and harm reduction.

METHODS: A scoping review was conducted using Levac et al.'s enhancement of Arksey and O'Malley's framework. A systematic search of MEDLINE (PubMed), PsycInfo, Embase, ProQuest Health & Medical, and ProQuest Psychology was performed on August 3, 2024, yielding 87 articles addressing pharmacists' knowledge, attitudes, and practices related to SUD and harm reduction.

RESULTS: Pharmacists generally acknowledge the efficacy of medications for opioid use disorder (MOUDs) in reducing opioid-related mortality but often hold stigmatizing beliefs about individuals with SUDs. While supportive of harm reduction strategies, such as naloxone distribution and needle and syringe programs, engagement varies widely. Significant gaps in education and training persist, leaving pharmacists with limited confidence and practical experience in SUD care, despite their reported familiarity with MOUDs and naloxone pharmacology.

abstract = {Neurodegenerative diseases (NDDs) such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis pose considerable therapeutic challenges, not only due to their complex pathophysiology, but also because any effective drug must be capable of penetrating the brain. Inflammation is a key feature of NDDs. Increasingly, the complement system, long studied in the context of host defence, has emerged as a central player in the brain, with roles extending far beyond its classical immune functions. Complement contributes to synaptic pruning and immune surveillance, but when dysregulated, it can drive chronic inflammation, synapse loss, and neurodegeneration. Complement is also implicated in neurodevelopmental and neuropsychiatric diseases, including schizophrenia and mood disorders, where overactivation of the cascade impacts brain maturation and circuit stability. In this review, we take a broad view of roles of the complement system in both health and disease in the central nervous system (CNS). We summarise key mechanisms through which complement contributes to pathology, discuss emerging therapeutic strategies, and consider major hurdles in CNS drug development, including brain delivery and the need for patient stratification. As our understanding of the pathological roles of the complement system in the brain advances, it is becoming clear that complement therapeutics may offer a novel approach in slowing neurodegeneration, and in addressing a broader spectrum of disorders affecting the brain.},

abstract = {Neurodegenerative disorders (ND) are accompanied by neuronal death because of progressive destruction in neuronal structure and function. Due to various neurological conditions, there is a significant number of deaths every year around the world. The healthcare burden is also increasing each year. Development and progress in nanotechnology enable the creation of nanocarriers that transport drugs to the site of disease, thereby enhancing the therapeutic performance of the drug. However, the transport of nanocarrier-based therapeutics to the brain is restricted by barriers such as the Blood-Brain Barrier (BBB) and Blood-Cerebrospinal Fluid Barrier (BCFB), which are further impeded by P-glycoproteins. Hence, current research and development focus on overcoming these obstacles. A biomimetic drug delivery system is one of the best ways to overcome these challenges. One of the promising biomimetic drug delivery systems is cell membrane-coated nanoparticles. In this review, we have comprehensively reviewed the recent progress and development in various cell membrane coated nanoparticle-based drug delivery systems for the effective management of a range of neurodegenerative diseases such as Alzheimer's Disease, Parkinson's Disease, Glioblastoma, Ischemic Stroke, Huntington's Disease, Amyotrophic Lateral Sclerosis, Glioma, Peripheral Nerve Injury, and Motor Neuron Disorder. We also reviewed the challenges associated with cell membrane-coated nanoparticles, such as biosafety hurdles, toxicity, regulatory requirements, and clinical translation. Ultimately, we provided the conclusions and future research directions that must be investigated to overcome the current limitations.},

abstract = {Neurodegenerative diseases involve toxic protein aggregation. Recent evidence suggests that biomolecular phase separation, a process in which proteins and nucleic acids form dynamic, liquid-like condensates, plays a key role in this aggregation. Optogenetics, originally developed to control neuronal activity with light, has emerged as a powerful tool to investigate phase separation in living systems. This is achieved by fusing disease-associated proteins to light-sensitive oligomerization domains, enabling researchers to induce or reverse condensate formation with precise spatial and temporal control. This review highlights how optogenetic systems such as OptoDroplet are being used to dissect the mechanisms of neurodegenerative disease. We examine how these tools have been applied in models of neurodegenerative diseases, such as amyotrophic lateral sclerosis, Alzheimer's, Parkinson's, and Huntington's disease. These studies implicate small oligomeric aggregates as key drivers of toxicity and highlight new opportunities for therapeutic screening. Finally, we discuss advances in light-controlled dissolution of condensates and future directions for applying optogenetics to combat neurodegeneration. By enabling precise, dynamic control of protein phase behavior in living systems, optogenetic approaches provide a powerful framework for elucidating disease mechanisms and informing the development of targeted therapies.},

abstract = {Recent investigations into the neuroepigenome of the brain are providing unparalleled understanding into the impact of post-translational modifications (PTMs) of histones in regulating dynamic gene expression patterns required for adult brain cognitive function and plasticity. Histone acetylation is one of the most well-characterized PTMs shown to be required for neuronal function and cognition. Histone acetylation initiates neural circuitry plasticity via chromatin control, enabling neurons to respond to external environmental stimuli and adapt their transcriptional responses accordingly. While interplay between histone acetylation and deacetylation is critical for these functions, dysregulation during the aging process can lead to significant alterations in the neuroepigenetic landscape. These alterations contribute to impaired cognitive functions, neuronal cell death, and brain atrophy, all hallmarks of age-related neurodegenerative disease. Significantly, while age-related generation of DNA mutations remains irreversible, most neuroepigenetic PTMs are reversible. Thus, manipulation of the neural epigenome is proving to be an effective therapeutic strategy for neuroprotection in multiple types of age-related neurodegenerative disorders (NDs) that include Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS) and Huntington's disease (HD). Here, we highlight recent progress in research focusing on specific HAT-based neuroepigenetic mechanisms that underlie cognition and pathogenesis that is hallmarked in age-related NDs. We further discuss how these findings have potential to be translated into HAT-mediated cognitive-enhancing therapeutics to treat these debilitating disorders.},

abstract = {BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that leads to nerve atrophy. Ultrasonography has a significant role in the diagnosis of ALS.

AIM: We aimed to sonographically assess the size of all peripheral nerves and cervical nerve roots in ALS compared to controls.

METHODS: We searched MEDLINE (PubMed), Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, and Scopus using comprehensive MeSH terms for the keywords nerve, ultrasound, and ALS. We extracted data regarding cross-sectional area (CSA) or diameter for the following nerves: vagus, phrenic, tibial, fibular, sural, radial, ulnar, and median nerves, and the roots of C5, C6, C7, and C8 in both ALS patients and controls.

RESULTS: Our study included 2683 participants, of which 1631 were ALS patients (mean age = 60.36), 792 were healthy controls (mean age = 57.79), and 260 were patients with other neurological disorders. ALS patients had significantly smaller nerve size compared to controls. Nerve size differences were observed in the vagus nerve [MD = -0.23], phrenic nerve [MD = -0.25], C5 nerve root [SMD = -0.94], C6 nerve root [SMD = -1.56], C7 nerve root [SMD = -1.18], C8 nerve root [MD = -1.9], accessory nerve [MD = -0.32], sciatic nerve [MD = -11], tibial nerve [MD = -0.68], sural nerve [MD = -0.32,], ulnar nerve [MD = -0.80], and median nerve [MD = -1.21].

CONCLUSIONS: Our findings showed that ALS patients have a sonographically smaller nerve size than healthy controls. Therefore, this is a potential marker for neuronal diseases.},

abstract = {Metal exposure is a potential risk factor for amyotrophic lateral sclerosis (ALS). Increasing evidence suggests that elevated levels of DNA damage are present in both familial (fALS) and sporadic (sALS) forms of ALS, characterized by the selective loss of motor neurons in the brain, brainstem, and spinal cord. However, identifying and differentiating initial biomarkers of DNA damage response (DDR) in both forms of ALS remains unclear. The toxicological profiles from the Agency for Toxic Substances and Disease Registry (ATSDR) and our previous studies have demonstrated the influence of metal exposure-induced genotoxicity and neurodegeneration. A comprehensive overview of the ATSDR's toxicological profiles and the available literature identified 15 metals (aluminum (Al), arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), nickel (Ni), selenium (Se), uranium (U), vanadium (V), and zinc (Zn)) showing exposure-induced genotoxicity indicators associated with ALS pathogenesis. Genetic factors including mutations seen in ALS types and with concomitant metal exposure were distinguished, showing that heavy metal exposure can exacerbate the downstream effect of existing genetic mutations in fALS and may contribute to motor neuron degeneration in sALS. Substantial evidence associates heavy metal exposure to genotoxic endpoints in both forms of ALS; however, a data gap has been observed for several of these endpoints. This review aims to (1) provide a comprehensive overview of metal exposure-induced genotoxicity in ALS patients and experimental models, and its potential role in disease risk, (2) summarize the evidence for DNA damage and associated biomarkers in ALS pathogenesis, (3) discuss possible mechanisms for metal exposure-induced genotoxic contributions to ALS pathogenesis, and (4) explore the potential distinction of genotoxic biomarkers in both forms of ALS. Our findings support the association between metal exposure and ALS, highlighting under or unexplored genotoxic endpoints, signaling key data gaps. Given the high prevalence of sALS and studies showing associations with environmental exposures, understanding the mechanisms and identifying early biomarkers is vital for developing preventative therapies and early interventions. Limitations include variability in exposure assessment and the complexity of gene-environment interactions. Studies focusing on longitudinal exposure assessments, mechanistic studies, and biomarker identification to inform preventative and therapeutic strategies for ALS is warranted.},

abstract = {PURPOSE: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative condition with swift progression. The devastating impact of ALS affects the health-related quality of life (HRQoL) of informal carers. Various person reported outcome measures (PROMs) have been used to assess HRQoL in informal carers in ALS, yet their validity remains unclear. This review aimed to identify and evaluate the content validity of HRQoL PROMs for informal carers in ALS.

METHODS: This review was conducted according to best practice COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. Two literature searches were conducted in November 2023 and April 2024 across MEDLINE, PsycINFO, Embase, CINAHL, the Cochrane Database of Systematic Reviews, CENTRAL and Google Scholar, to identify HRQoL PROMs used with informal carers in ALS, PROM development articles, and psychometric literature. Evidence synthesis followed COSMIN guidance.

RESULTS: 12,276 articles were screened, and 109 PROMs were identified, with 43 undergoing full COSMIN assessment. Content validity ratings were 'Inconsistent' or 'Insufficient' for all PROMs. All PROMs, except the CarerQoL, were rated 'Insufficient' for comprehensiveness. Only 18.6% of PROMs included informal carers in development. Quality of evidence supporting content validity ratings was 'Very Low' for 93% of PROMs.

CONCLUSION: HRQoL PROMs used with informal carers in ALS lack evidence to support their content validity, restricting their utility for this purpose. Existing literature on the impact of caring in ALS on informal carers' HRQoL should be interpreted cautiously. Further research is required to establish the content validity of HRQoL PROMs used for this cohort.},

This review introduces the generation of reactive oxygen species (ROSs) in the nervous system, the cellular oxidative damage, and the high sensitivity of the brain to ROSs. The literature review focuses on the roles of oxidative stress in neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Oxidative stress occurs when excessively produced free radicals are beyond the capability of endogenous antioxidants to scavenge, leading to the oxidation of proteins, lipids, and nucleic acids, stimulating neuroinflammatory responses, causing neuronal dysfunction, senescence, and death. The dysfunctional mitochondria and aberrant activities of metabolic enzymes are the major source of ROSs. The high vulnerability of the nervous system to ROSs underlies the critical roles of oxidative stress in neurodegenerative diseases. Gene mutations and other risk factors promote the generation of ROSs, which have been considered a crucial force causing the main pathological features of AD, PD, HD, and ALS. As a result, antioxidants hold therapeutic potential in these neurodegenerative diseases. The elucidation of the pathogenic mechanisms of oxidative stress will facilitate the development of antioxidants for the treatment of these diseases.},

abstract = {BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to severe functional decline and death, imposing significant physical, emotional, and ethical burdens on patients and healthcare providers. With no curative treatment, ALS care depends on the early and sustained integration of palliative care to address complex and evolving needs. Nurses play a pivotal role in this process, yet their lived experiences remain underexplored. This study aimed to synthesize qualitative evidence on nurses' experiences in ALS care, with a focus on emotional, ethical, and palliative dimensions.

METHODS: A meta-synthesis of qualitative studies was conducted using Sandelowski and Barroso's four-step method. A systematic search across five databases identified eight studies exploring nurses' experiences with ALS care. Thematic synthesis was applied to extract overarching patterns.

RESULTS: Three core themes emerged: (1) Relational Dimension: From challenges to empathy and Trust and mistrust-emphasizing communication barriers and the value of relational trust; (2) Care Dimension: Competence, Palliative care needs, and Rewarding complexity-highlighting the emotional demands of care, the need for timely palliative integration, and the professional meaning derived from ALS care; (3) Ethical Dimension: Medical interventionism and Patient-centered values-exploring dilemmas around life-sustaining treatments, patient autonomy, and end-of-life decisions.

CONCLUSION: Nurses in ALS care face complex emotional and ethical challenges that call for strong institutional support and palliative training. Enhancing palliative care integration from diagnosis, alongside targeted education and psychological support, is crucial to improving care quality and sustaining the well-being of both patients and nurses.},

The disease's pathogenesis involves a prolonged preclinical phase of neuronal proteinopathy, particularly TDP-43 accumulation, which eventually leads to motor neuron death and overt ALS. This review discusses the difficulties in detecting this transition and the implications for early therapeutic intervention. It also addresses the involvement of both the upper and lower motor neuron systems, as well as the importance of following presymptomatic patients with genetic mutations. The significance of understanding the distinct processes of TDP-43 deposition and subsequent neuronal degeneration in developing effective treatments is emphasised.},

It comprises a complex network of interactions involving the endocrine, immune, autonomic, and enteric nervous systems. The balance of this bidirectional pathway depends on the composition of the gut microbiome and its metabolites. While the causes of neurodegenerative diseases (NDDs) vary, the gut microbiome plays a crucial role in their development and prognosis. NDDs are often associated with an inflammation-related gut microbiome. However, restoring balance to the gut microbiome and reducing inflammation may have therapeutic benefits. In particular, introducing short-chain fatty acid-producing bacteria, key metabolites that support gut homeostasis, can help counteract the inflammatory microbiome. This strong pathological link between the gut and NDDs underscores the gut-brain axis (GBA) as a promising target for therapeutic intervention. This review, by scrutinizing the more recent original research articles published in PubMed (MEDLINE) database, emphasizes the emerging notion that GBA is an equally important pathological marker for neurological movement disorders, particularly in Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis, Huntington's disease and neurotraumatic disorders such as traumatic brain injury and spinal cord injury. Additionally, the GBA presents a promising therapeutic target for managing these diseases.},

The various functions of the sigma-1 receptor highlight its role as a central modulator of neuronal health and may be a promising pharmacological target across multiple neurodegenerative conditions. Herein, we provide an overview of the current pharmacological understanding of the sigma-1 receptor with an emphasis on the signaling mechanisms involved. We examine its pathological implications in common neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, and multiple sclerosis. We then highlight how sigma-1 receptor modulation may influence disease progression as well as potential pharmacological mechanisms to alter disease outcomes. The translational potential of sigma-1 receptor therapies is discussed, as well as the most up-to-date results of ongoing clinical trials.

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of upper and lower motor neurons, leading to muscle weakness, paralysis, and ultimately respiratory failure. Despite advances in understanding its genetic basis, particularly mutations in Chromosome 9 Open Reading Frame 72 (C9orf72), superoxide dismutase 1 (SOD1), TAR DNA-binding protein (TARDBP), and Fused in Sarcoma (FUS) gene, current diagnostic methods result in delayed intervention, and available treatments offer only modest benefits. This review examines innovative approaches transforming ALS research and clinical management. We explore emerging biomarkers, including the fluid-based markers such as neurofilament light chain, exosomes, and microRNAs in biological fluids, alongside the non-fluid-based biomarkers, including neuroimaging and electrophysiological markers, for early diagnosis and patient stratification. The integration of multi-omics data reveals complex molecular mechanisms underlying ALS heterogeneity, potentially identifying novel therapeutic targets. We highlight current gene therapy strategies, including antisense oligonucleotides (ASOs), RNA interference (RNAi), and CRISPR/Cas9 gene editing systems, alongside advanced delivery methods for crossing the blood-brain barrier. By bridging molecular neuroscience with bioengineering, these technologies promise to revolutionize ALS diagnosis and treatment, advancing toward truly disease-modifying interventions for this previously intractable condition.},
