abstract = {Familial forms of ALS are potential candidates for gene-directed therapies, but many recently identified genes remain poorly characterized. Here, we provide a comprehensive clinical, neuropathological, and biochemical description of fALS caused by the heterozygous p.R15L missense mutation in the gene CHCHD10. Using a cross-sectional study design, we evaluate five affected and nine unaffected individuals from a large seven-generation pedigree with at least 68 affected members. The pedigree suggests a high (68 - 81%) but incomplete disease penetrance. Through cloning of the disease-allele from distant members of the family, we establish the disease haplotype in the family. Notably, the haplotype was distinct from that of a previously reported p.R15L mutation carrier with ALS, demonstrating that the variant is in a mutational hotspot. The clinical presentation was notable for being highly stereotyped; all affected individuals presented with the rare ALS variant Flail Arm Syndrome (FAS; also known as, brachial amyotrophic diplegia or Vulpian-Bernhardt Syndrome), suggesting greater involvement of the cervical spinal cord. Consistently, neuropathology from one family member demonstrated substantially increased CHCHD10 protein aggregation and neuronal loss (though absent TDP-43 pathology) in the cervical vs. lumbar spinal cord. This FAS phenotype could be captured by a simple timed finger tapping task, suggesting potential utility for this task as a clinical biomarker. Additionally, through analysis of fibroblast lines from 12 mutation carriers, isogenic iPSC cells, and a knockin mouse model, we determined that CHCHD10 with the R15L variant is stably expressed and retains substantial function both in cultured cells and in vivo , in contrast to prior reports. Conversely, we find loss of function (LoF) variants are more common in the population but are not associated with a highly penetrant form of ALS in the UK Biobank (31 in controls; 0 in cases). Together, this argues against LoF and in favor of toxic gain-of-function as the mechanism of disease pathogenesis, similar to the myopathy-causing variants in CHCHD10 (p.G58R and p.S59L). Finally, through proteomic analysis of CSF of variant carriers, we identify that CHCHD10 protein levels are elevated approximately 2-fold in mutation carriers, and that affected and unaffected individuals are differentiated by elevation of two neurofilaments: neurofilament light chain (NfL) and Peripherin (PRPH). Collectively, our findings help set the stage for gene-directed therapy for a devasting form of fALS, by establishing the likely disease mechanism and identifying clinical and fluid biomarkers for target engagement and treatment response.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by motor neuron loss. Current FDA-approved treatments offer only modest benefits. Connexins (Cx), proteins that mediate intercellular communication have emerged as potential therapeutic targets, with increased Cx hemichannel (HC) activity observed in ALS models, and blocking Cx HC activity prevents motor neuron loss in vitro. Boldine, a natural compound with both Cx HC-blocking and antioxidant properties, has shown neuroprotective potential. This study investigated boldine's effects in ALS models. In vitro, spinal cord cell cultures exposed to conditioned media from mutant SOD1[G93A] astrocytes showed a 50% reduction in motor neuron survival, elevated Cx HC activity, and increased reactive oxygen species (ROS). Boldine treatment significantly reduced Cx HC activity and ROS, and increased motor neuron viability. In vivo, oral boldine was well-tolerated in male mutant SOD1[G93A] mice starting at 7 weeks of age. Mice receiving 50 mg/kg/day showed a median survival increase of 9 days (132 vs. 123 days), though not statistically significant. Functional assessments revealed delayed disease progression: in the horizontal ladder rung walk test, boldine-treated mice exhibited a 36.8% reduction in crossing time and 21.2% fewer stepping errors. Improved scores were also observed on the Basso Mouse Scale at later stages, indicating preserved locomotor function. However, boldine had no significant effect in the rotarod test. These results support boldine's neuroprotective effects in ALS, particularly in fine motor coordination and locomotor performance. Its reduction of Cx HC activity and oxidative stress highlights boldine's promise as a potential therapeutic candidate for ALS.},

Building on a model from Camden, New Jersey, this protocol was approved in 2022 in response to rising overdose deaths and was fully implemented across Delaware's advanced life support (ALS) EMS agencies in April 2023. Eligible patients-those 18 years or older, resuscitated with naloxone, and able to consent-received up to 24 mg of sublingual buprenorphine along with ondansetron for nausea. Between April 2023 and May 2025, paramedics administered 118 buprenorphine doses to 105 patients, with improvement in withdrawal symptoms reported after 63.6% of doses. Despite a rise in patient ineligibility due to altered mental status-likely linked to sedating adulterants,such as xylazine and medetomidine,in regional street drugs-paramedics increased the percentage of eligible patients accepting offered buprenorphine from 19.0% to 22.8% between the first and second year of the program. This protocol not only addresses acute overdose management in the field but also connects patients to ongoing care, aiming to reduce mortality and expand access to medications for opioid use disorder.},

We previously developed a mouse model in which TDP-43 is selectively deleted from motor neurons (ChAT-Cre;Tardbp [f/f]) that mimics the early stages of ALS. Here, we demonstrate that intravenous delivery of a blood-brain-barrier (BBB) permeable AAV capsid expressing our rationally designed splicing repressor CTR (AAV-PHP.eB-CTR) in symptomatic ChAT-Cre;Tardbp [f/f] mice markedly slowed disease progression and prevented paralysis. Systemic delivery of AAV-PHP.eB-CTR led to transduction of ∼80% of spinal motor neurons, repression of TDP-43-associated cryptic exons within motor neurons expressing CTR, and attenuation of motor neuron loss. Notably, the addition of the TARDBP 3'UTR autoregulatory element to CTR maintained its expression within a physiological range. In control littermates that received AAV-PHP.eB-CTR and were monitored for >20 months, grip strength and body weight remained normal, and no histopathological abnormalities were observed, underscoring a favorable safety profile for this gene therapy. These results provide preclinical proof-of-concept that BBB-crossing AAV delivery of CTR can rescue motor neuron disease through the restoration of TDP-43 function, offering a promising mechanism-based therapeutic strategy for ALS.},

Participants were evaluated using tools like the Pittsburgh Sleep Quality Index (PSQI) and ALS Functional Rating Scale-Revised (ALSFRS-R). Regression models identified factors affecting sleep disorders and quality. Patients with sleep disorders were more likely to have non-motor symptoms like anxiety, depression, pain, and excessive daytime sleepiness compared to those without. Fatigue severity and anxiety levels were identified as independent influencing factors of sleep disorders. Additionally, fatigue, anxiety, pain intensity, and disease progression rate were significantly linked to sleep quality. This study is the first comprehensive analysis of sleep-related factors in Chinese ALS patients, highlighting the crucial roles of fatigue, anxiety, pain, and disease progression rate. It provides a basis for future personalized, non-pharmacological interventions tailored to the specific needs of ALS patients.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease resulting in the progressive loss of motor neurons in the brain and spine. More than 95% of cases are pathologically characterized by the cytoplasmic accumulation of hyperphosphorylated and ubiquitinated transactive response DNA-binding protein 43 (TDP-43). Multiple mouse models with TDP-43 accumulation have been developed, however, whether they recapitulate molecular features of ALS pathology is unclear. Given the lack of curative treatment for ALS, there is an urgent need to identify the precise biological processes contributing to disease pathogenesis for the development of effective therapeutic treatments. Thus, in this study we employed label-based untargeted proteomics to characterize the ALS proteome and related biological processes in the spinal cord and brain of TDP-43[Q331K] mice, a transgenic mouse model of ALS and the motor cortex and the cervical, thoracic, and lumbar spinal cord regions from humans. In humans, we observed highly overlapping responses across the four tissues examined, primarily related to the upregulation of immune processes and the downregulation of mitochondrial function. In contrast, TDP-43[Q331K] mice demonstrate a lack of enrichment for immune activation and the opposite regulation of mitochondrial processes. A meta-analysis of previously published mouse datasets identified the Ubqln2 knock-out mouse model as showing stronger parallels with our late-stage human ALS. Overall, this study provides in-depth analysis of the site-specific dysregulated proteomes and their associated functional processes across species. Thereby, identifying potential therapeutic targets while emphasizing the limitations of specific mouse models at certain timepoints in recapitulating ALS-related processes for future model development.},

abstract = {PURPOSE: Adductor lesions (ALs) frequently coexist with osteitis pubis (OP) in athletes, yet the prevalence and clinical impact of different AL types have not been comprehensively evaluated. This study aimed to determine the frequency of various AL types using magnetic resonance imaging (MRI) and to investigate their association with clinical outcomes in athletes with OP.

MATERIALS AND METHODS: This retrospective cross-sectional study included male athletes aged 18-45 years with MRI-confirmed OP. ALs were classified into four types on the basis of MRI: type 1 (strain), type 2 (tendon avulsion), type 3 (tendinopathy), and type 4 (secondary cleft sign). Types 1-2 were considered acute, and types 3-4 chronic lesions. The relationships between AL types, age, symptom side, return to sport (RTS), and hip outcome score (HOS) were analyzed.

RESULTS: Among 132 athletes with OP, 90% had concurrent AL, while 10% had isolated OP. Type 3 AL was the most frequent type (77.3%), followed by type 4 (23.5%), type 1 (15.9%), and type 2 (2.3%). Logistic regression revealed that type 3 was more likely to be found in younger athletes, while types 1 and 4 were found in older athletes. Although 95% of athletes had bilateral OP, 72% reported unilateral symptoms. The symptom side showed better consistency with the AL side than the OP side (Cohen's kappa = 0.489 versus 0.057). All athletes were treated conservatively, 50 chronic AL cases were applied also injection (31 corticosteroid-CS, 19 platelet reach plasma-PRP). Athletes with isolated OP achieved a higher RTS rate than those with AL (100% versus 75%, p = 0.033). RTS rates were higher in acute AL cases than in chronic cases (91% versus 72%) and in CS injections than in PRP injections (80% versus 63%), but without statistical significance. HOS scores were comparable across groups.

CONCLUSIONS: Adductor lesions, particularly chronic types, are highly prevalent in athletes with OP. While age influences the type of AL, the symptom side is compatible with the AL side, regardless of the type. RTS rates are more satisfactory in isolated OP and acute AL cases, but chronic AL cases were less successful in RTS outcomes despite injection treatments. These findings underscore the importance of identifying and classifying ALs for prognosis and treatment strategy in athletic groin pain.

abstract = {BACKGROUND: Leprosy, a neglected tropical disease, remains a significant global health issue, with India accounting for nearly 60% of cases in 2022. Untreated Leprosy can result in irreversible disabilities and lead to social stigma, significantly affecting the lives of patients and their families. This study explores the barriers faced by women with leprosy in accessing healthcare and other factors that contributed to the development of Grade 2 disability in India.

METHODS: Qualitative data were gathered through 20 interviews with women affected by leprosy at the Sivananda Rehabilitation Home, a leprosy clinic in Hyderabad, India. An interview guide was developed to conduct semi-structured interviews, specifically regarding the time between the onset of symptoms, diagnosis, and treatment start. An inductive analysis followed by the application of Levesque et al.’s framework was undertaken to identify themes and patterns in the participants’ experiences with the disease and treatment.

RESULTS: Six key themes were identified. The social environment plays a pivotal role in disease progression, with participants often prioritising societal expectations over their own health, such as being good wives and mothers. Stigmatisation led to social isolation, as many women avoided contact outside their families to hide deformities. Most participants visited several healthcare facilities before receiving a diagnosis, facing financial and emotional burdens. Communication gaps were evident both within healthcare facilities - where companions were sometimes informed before the patient – and in their social environments. Finally, individual factors such as lack of knowledge, awareness, and trust in medical advice also contributed to care-seeking delays.

CONCLUSIONS: This study highlights significant gaps in healthcare access for women with leprosy in India. Family dynamics, societal roles, and stigma delay care, while physical and emotional burdens add to challenges. Communication gaps and limited awareness further reinforce neglect and mistrust. Addressing these barriers is crucial for effective policy and program implementation to reduce the burden of leprosy among women.

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, characterized by progressive loss of motor neurons. Due to heterogeneity in both cause and clinical phenotype, accuracy of diagnosis and efficacy of treatment remain challenging. An evolving body of evidence point to the importance of the "gene-time-environment" hypothesis in ALS onset and progression. Despite extensive research, understanding of the complex environmental risk factors remains fragmented. In this study, we comprehensively analyzed the associations between trace elements, biochemical signatures, and modifiable risk factors among ALS patients stratified by age, sex, type of onset, disease severity, and progression. Specifically, we investigated blood concentrations of cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), calcium (Ca), magnesium (Mg), and iron (Fe) levels in 121 participants. Moreover, we examined the associations between trace metals, biochemical indicators including serum ferritin (SF), blood glucose, cholesterol (CHOL), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), cerebrospinal fluid (CSF) cell count, CSF total protein, as well as history of hypertension, hazardous chemical exposure, drinking, and smoking in ALS patients. Specifically, we report that high Fe levels were found in male and spinal-onset patients. Moreover, high serum ferritin was positively associated with age of onset, blood iron and glucose, as well as high disease severity. Results from this study highlight the complex characteristics of ALS and provide new insight for understanding the intricate relationship between disease phenotype, metal homeostasis, and modifiable risk factors.},

Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was utilised for development of the PACTALS management guidelines. Nine broad research questions, divided into sections, were addressed. Evidence was derived from existing Cochrane reviews, systematic reviews, meta-analysis, and randomized controlled trials (RCT) along with consensus when evidence was limited. Recommendations were provided for diagnostic pathways, use of disease modifying therapies, appropriateness of multidisciplinary care models, management of respiratory dysfunction, communication and nutrition, addressing symptoms that affect the quality of life, managing cognitive, behavioural and emotional symptoms as well as appropriate implementation of palliative care services and addressing end-of-life issues.

abstract = {The voltage-gated sodium channel Nav1.6, encoded by the sodium voltage-gated channel alpha subunit 8 gene, is a crucial regulator of neuronal excitability, with widespread expression throughout the central and peripheral nervous systems. Recent breakthroughs in structural biology, particularly the elucidation of the cryo-EM architecture of Nav1.6 at a resolution of 0.31 nm, have provided unprecedented insights into its molecular organization and functional modulation. As a key mediator of action potential initiation and propagation, Nav1.6 possesses unique biophysical properties, including persistent and resurgent sodium currents that critically influence neuronal firing patterns. This comprehensive review synthesizes current knowledge on the physiological functions and pathological roles of Nav1.6 in multiple neurological conditions. Key findings include the following: (1) Epilepsy studies reveal more than 250 sodium voltage-gated channel alpha subunit 8 mutations with distinct genotype-phenotype correlations, where gain-of-function variants lead to severe epileptic encephalopathies, while loss-of-function variants are associated with generalized epilepsy, highlighting the potential of Nav1.6-selective blockers such as XEN901 and GS967. (2) In Alzheimer's disease, Nav1.6 mediates amyloid-β oligomer-induced neuronal hyperexcitability through amyloid precursor protein-dependent membrane trafficking and regulates beta-secretase 1 expression via nuclear factor of activated T cells 1 signaling, suggesting novel disease-modifying strategies. (3) Parkinson's disease research has demonstrated that Nav1.6 upregulation in reactive astrocytes in the globus pallidus contributes to motor deficits through calcium-mediated abnormalities in neuronal synchronization. (4) Amyotrophic lateral sclerosis involves Nav1.6-dependent cortical hyperexcitability preceding motor neuron degeneration, with riluzole showing partial efficacy through sodium current modulation. (5) Multiple sclerosis pathophysiology features Nav1.6 redistribution in demyelinated axons, which drives calcium-dependent axonal injury via reverse Na+/Ca2+ exchange. (6) Chronic pain mechanisms involve Nav1.6 overexpression in dorsal root ganglia neurons, regulated by the p38 mitogen-activated protein kinase and tumor necrosis factor-α signaling pathways. (7) Traumatic brain injury models show that exercise-induced cognitive improvement is correlated with the normalization of Nav1.6-mediated excitability. Therapeutic development has progressed from nonselective sodium channel blockers to precision approaches, including state-dependent pore blockers designed using structural insights; allosteric modulators targeting specific conformations; gene therapy strategies using clustered regularly interspaced short palindromic repeats and antisense oligonucleotides; and miRNA-based regulation of channel expression. Current challenges include achieving sufficient subtype selectivity, optimizing blood-brain barrier penetration, and developing clinically relevant biomarkers for patient stratification. Future directions emphasize the integration of advanced technologies-such as singlecell multiomics to map neuronal subtype-specific expression patterns, patient-derived organoids for personalized drug testing, and machine learning-assisted drug design-to accelerate translation. Large-scale collaborative efforts will be essential to validate therapeutic candidates and establish genotype-guided treatment protocols for Nav1.6-related disorders.},

abstract = {Background and Objectives: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting the upper and lower motor neurons, with a bleak prognosis and few treatment options. Non-invasive brain stimulation (NIBS) techniques, such as repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), represent emerging approaches aimed at modulating cortical hyperexcitability, a relevant pathogenetic mechanism in ALS. Materials and Methods: A systematic review of the literature was conducted following the PRISMA guidelines, exploring the Scopus and PubMed databases from April to June 2025 with terms related to ALS and NIBS. A total of 18 relevant studies were selected from the initial 708 articles, analysing stimulation protocols, clinical and neurophysiological outcomes, and associated biomarkers; their validity was assessed using the revised Cochrane risk-of-bias (RoB2) tool. Results: The selected studies were extremely heterogeneous, with NIBS techniques, including magnetic (rTMS, cTBS, tSMS) and electrical (tDCS) stimulation, showing variable effects. Low-frequency protocols (1 Hz rTMS) and cTBS showed a slight slowing of clinical progression, while prolonged home stimulation with tDCS and tSMS showed more significant improvements in terms of efficacy, tolerability, and adherence. The main limitations concern the heterogeneity of patients and protocols and the lack of standardised biomarkers, which is why the analysis remained at a descriptive level. The use of telemonitoring and caregiver training are essential to ensure safety and accessibility. Conclusions: NIBS represents a promising therapeutic approach for ALS, but further multicentre, standardised studies with prolonged follow-up are needed. Future strategies should include customisation of stimulation, combination with other therapies, and extension of application to pre-symptomatic phases.},

abstract = {Subacute combined degeneration (SCD) is a neurological disorder primarily caused by vitamin B12 deficiency. This condition leads to progressive demyelination and axonal damage, predominantly affecting the dorsal and lateral columns of the spinal cord. This review provides a comprehensive overview of SCD, detailing its complex etiology, pathophysiology, and clinical presentation. We highlight the critical role of magnetic resonance imaging (MRI) in the diagnostic process, discussing both the characteristic spinal cord findings and the more subtle intracranial abnormalities. Furthermore, we address the diagnostic challenges presented by conditions that mimic SCD in MRI, such as multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS). We conclude by outlining current treatment pathways and identifying key areas for future research, including the use of advanced neuroimaging techniques and the potential for new therapeutic approaches. This updated synthesis aims to provide a clear framework for clinicians and researchers to better understand and manage SCD.},

abstract = {The increasing production and release of synthetic organic chemicals, including pharmaceuticals, into our environment has allowed these substances to accumulate in our surface water systems. Current purification technologies have been unable to eliminate these pollutants, resulting in their ongoing release into aquatic ecosystems. This study focuses on cloperastine (CPS), a cough suppressant and antihistamine medication. The environmental impact of CPS usage has become a concern, mainly due to its increased detection during the COVID-19 pandemic. CPS has been found in wastewater treatment facilities, effluents from senior living residences, river waters, and sewage sludge. However, the photosensitivity of CPS and its photodegradation profile remain largely unknown. This study investigates the photodegradation process of CPS under simulated tertiary treatment conditions using UV photolysis, a method commonly applied in some wastewater treatment plants. Several transformation products were identified, evaluating their kinetic profiles using chemometric approaches (i.e., curve fitting and the hard-soft multivariate curve resolution-alternating least squares (HS-MCR-ALS) algorithm) and calculating the reaction quantum yield. As a result, three different transformation products have been detected and correctly identified. In addition, a comprehensive description of the kinetic pathway involved in the photodegradation process of the CPS drug has been provided, including observed kinetic rate constants.},

abstract = {Frailty is a geriatric condition with multidimensional consequences that strongly affect older adults' quality of life. The lack of a universal standard to describe, diagnose, and treat frailty further complicates this situation. Nowadays, multitudinous frailty assessment tools are applied depending on the regional and clinical context, adding complexity by increasing heterogeneity in the definition and characterization of frailty. Better insights into the causes and pathophysiology of frailty and its early stages are required to establish strong and accurately tailored treatment rationales for frail patients. We analysed participants aged 60 and above using cross-sectional biochemical and survey data from the Berlin Aging Study II (BASE-II, N=1512, pre-frail=470, frail=14), applying machine-learning techniques to investigate determinants of physical frailty measured by Fried et al.'s 5-item frailty phenotype. Our findings highlight new prognostic sex-specific biomarkers of pre-frailty (the early stage of frailty) with possible clinical applications, enriching the current sex-agnostic diagnostic scores with easy monitorable physical and physiological characteristics. Low appendicular lean mass and high fat composition in men, or vitamin D deficiency and high white blood cell counts in women, emerged as strong indicators of the respective pre-frailty profiles. Because the number of fully frail individuals was extremely small (n = 14, <1%), our findings should be interpreted as reflecting predictors of pre-frailty, not of frailty itself. We conclude that understanding the development of frailty remains a complex challenge, and that sex-specific differences must be considered by clinical geriatricians and researchers.},

abstract = {Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative disorders characterized by the expansion of GGGGCC (G4C2) repeats in the C9orf72 gene and progressive motor neuron degeneration. A key pathological hallmark of these diseases is the accumulation and cytoplasmic mislocalization of dipeptide repeat (DPR) proteins, particularly poly(GR), which are neurotoxic. Enhancing the clearance of poly(GR) represents a promising therapeutic strategy; however, the molecular mechanisms regulating poly(GR) turnover are not fully understood. Our previous work demonstrated that translationally stalled poly(GR) is targeted by the ribosome-associated quality control (RQC) pathway. In the present study, we identify the IRE1/Xbp1s signaling axis as an essential regulator of poly(GR) degradation. Ectopic expression of IRE1 or its downstream effector Xbp1s, as well as pharmacological activation of IRE1 using IXA4, significantly reduces poly(GR) protein levels in a Drosophila disease model, mammalian cell lines, fibroblasts derived from C9orf72-ALS patients, and a C9orf72 transgenic mouse model. Mechanistically, RNA-sequencing analysis reveals that IRE1/Xbp1s signaling upregulates heat shock protein Hsp70Ba, which plays a critical role in maintaining poly(GR) proteostasis. Additionally, we show that the Rictor/AKT/VCP pathway contributes to the translational regulation and turnover of poly(GR). Importantly, activation of IRE1, either through ectopic expression or IXA4 treatment, mitigates motor neuron loss in the C9orf72 mouse model. Collectively, our findings highlight the IRE1/Xbp1s axis as a key modulator of poly(GR) clearance and suggest its therapeutic potential in ALS/FTD.},

abstract = {BACKGROUND: Ofatumumab is a fully human anti-CD20 monoclonal antibody that selectively and highly depletes B cells. However, limited data on ofatumumab treatment are available in patients with neuromyelitis optica spectrum disorders (NMOSD). In this study, we aimed to evaluate the efficacy and safety of subcutaneous ofatumumab in patients with NMOSD.

METHODS: We conducted a retrospective multicenter cohort study of patients with NMOSD who received ofatumumab treatment at 15 tertiary hospitals in China. The primary outcome was the annualized relapse rate (ARR). The secondary outcomes included disability measures (Expanded Disability Status Scale score, EDSS; the Aminoff-Logue Disability Scale, ALS), changes in aquaporin-4 IgG (AQP4-IgG) titers, and safety profiles during ofatumumab treatment.

RESULTS: A total of 112 patients (88% female, median age 44.0 years with interquartile range [IQR 29.5-57.5]) received ofatumumab treatment for a median of 1.7 years (IQR: 1.1-2.0). The median ARR decreased significantly from 2.0 (IQR 0.7-10.0) before ofatumumab to 0 (IQR 0.0-0.0; p < 0.001) after ofatumumab. Twenty-two patients (20%) experienced 25 relapses, with 20 (80%) occurring within the first year of initiating ofatumumab treatment and 19 (76%) classified as minor. The EDSS score from start to the last follow-up also improved significantly (median: pre-treatment 3.5, IQR 2.0-6.5, post-treatment: 2.0, IQR1.0-3.5, p < 0.001). Among 94 patients, 71 (76%) showed reduced AQP4-IgG titers at last follow-up. Injection-related reactions were reported in 13 (12%) of 112 patients. Twenty-four infections occurred in 20 patients (18%) during the ofatumumab treatment, with 92% (22/24) being grade 1 or 2 (CTCAE version 5.0). Only 2 patients (2%) experienced pneumonia requiring hospitalization and recovered after antibiotic treatment (grade 3). Hypogammaglobulinemia was recorded in 14% (13/95) of patients and was not associated with infection.

CONCLUSIONS: Subcutaneous ofatumumab treatment significantly reduces the relapse risk, limits worsening of disability, and reduces AQP4-IgG titers in NMOSD. Moreover, the safety profiles were generally acceptable. Further research is necessary to explore the sustained clinical response of ofatumumab in NMOSD.},

The genetic polymorphism with tissue distribution ranging from the brain, limbic system, and adrenal cortex to neutrophils, monocytes, and macrophages is evident in MCRs. The mutations in MC1R, MC2R, MC3R, and MC4R genes are associated with risk of melanoma, familial glucocorticoid deficiency, obesity, and type 2 diabetes mellitus, respectively. Meanwhile, MC1R, MC2R, and MC5R genes are involved in the risk of major depressive disorder. Melanocortin receptors are involved in different inflammatory disorders, i.e., atopic dermatitis, autoimmune uveitis, sarcoidosis, respiratory diseases, multiple sclerosis, scleroderma, inflammatory bowel disease, amyotrophic lateral sclerosis, Alzheimer's disease, arthritis, and reperfusion injury. Several newer therapeutic agents related to MCRs have numerous advantages over the current anti-inflammatory drugs, demonstrating therapeutic relevance. Among them, α-MSH analogs play a role in atopic dermatitis and scleroderma, and MC1R agonist Dersimelagon has shown effectiveness in systemic sclerosis. The FDA has recently approved the repository corticotropin injection (RCI) to treat sarcoidosis. The FDA has also approved various melanocortin agonists, i.e., Bremelanotide, Afamelanotide, and Setmelanotide, for the treatment of hypoactive sexual desire disorder, Erythropoietic protoporphyria, and obesity, due to pro-opiomelanocortin and leptin receptor deficiency, respectively. Therefore, this review aims to summarize the function and genetic polymorphism of melanocortin receptors, regulatory pathways involving MCRs, and the existing evidence of the prime effect of MCRs on inflammatory responses via different mechanisms and their potential therapeutic use in inflammatory diseases.},

The resultant functional effects are being harnessed in the treatment of various neurological conditions; however, the fundamental mechanisms of action underlying tsDCS remain unclear. This ambiguity is largely attributed to the limited knowledge of the geometrical constraints of the EF in the polarized spinal regions. It is, then, essential to develop tools that enable researchers to plan tsDCS approaches in a controlled and systematic manner, ensuring the reproducibility of stimulation effects at spinal targets. With this paper, we aim to provide a comprehensive computational model of tsDCS intervention in mice to support further fundamental research in this area. Our model was constructed using high-resolution MRI scans of C57/B6 mice, which were segmented and reconstructed into a realistic mouse computational model. In vivo electrophysiological measurements of voltage gradients in SOD1 G93A mice were used to validate our model predictions in real-life scenarios. In both the modeling and in vivo studies, we employed a rostrocaudal arrangement of DC electrodes to replicate stimulation parameters that have proven effective for modulating murine spinal circuits. Both the computational and in vivo approaches yielded highly consistent results, with EF parameters primarily influenced by the distance between the target site and the tsDCS electrodes. We conclude that this developed model offers high accuracy in EF distribution and can significantly substantiate basic research in tsDCS.},

Primary disease events can be compensated transiently, delaying disease manifestation. To define potential therapy targets, here we studied how cells modify phosphoprotein signals, using preferentially affected nervous tissue from end-stage Atxn2-CAG100-KnockIn mice. The spinal cord phosphoproteome revealed massive hyperphosphorylations flanking the polyQ expansion in ATXN2 and for SQSTM1, and moderate hyperphosphorylations also for ALS proteins OPTN, UBQLN2, TNIP1 and TBK1-targeted TAX1BP1. Conversely, strong hypophosphorylations of WNK1, SPARCL1 and PSMD9 were found. Significant enrichments of SH3-containing proteins, autophagy / endocytosis factors, and actin modulators could be explained by N-terminal, polyQ-adjacent, proline-rich motifs (PRM) in ATXN2, suggesting that SCA2 pathogenesis is highly similar to Huntington's disease where neurotoxicity is mediated by abnormal polyQ-PRM-SH3 interactions. Validation of protein and mRNA levels were done in mouse spinal cord, and embryonic fibroblasts or patient fibroblasts after bafilomycin or arsenite treatment, observing polyQ-dependent OPTN deficiency and SQSTM1 induction impairment. Overall, this phosphoproteome profile identified and quantified the main cellular efforts in adapting autophagy pathways to the aggregation propensity of the ATXN2-N-term.},

abstract = {Descurainia sophia, an invasive weed in wheat fields of China, has developed notable resistance to the acetolactate synthase (ALS)-inhibiting herbicide tribenuron-methyl. In this study, a suspected resistant population (R) of D. sophia was investigated to assess its resistance level and elucidate the underlying mechanisms. Whole-plant bioassays revealed that the R population exhibited a 35.20-fold higher resistance index (RI) to tribenuron-methyl compared with a sensitive (S) population. Treatment with the cytochrome P450 inhibitor malathion partially reversed this resistance, indicating a metabolic component. Target-site resistance (TSR) analysis identified a mutation from proline (Pro) to histidine (His) or serine (Ser) at position 197 of the ALS gene in the R population. Additionally, high-performance liquid chromatography (HPLC) analysis indicated that enhanced tribenuron-methyl metabolism occurred in the R population compared with the S population. Three candidate P450 genes (CYP96A15, CYP81F1, CYP734A1), and one UDP-glycosyltransferase (UGT) gene (UGT84A1) were found to be upregulated in the R population, as verified by RNA sequencing and quantitative reverse transcription PCR (RT-qPCR). Candidate resistance genes were identified and expressed heterologously in Arabidopsis thaliana. Experimental data showed that compared with the green fluorescent protein (GFP) control group, the resistance of three transgenic Arabidopsis lines overexpressing the DsUGT84A1 gene to tribenuron-methyl was significantly increased. When all the plants in the GFP control group died, the fresh weight of these three transgenic lines remained above 20%. The above results fully confirm that the DsUGT84A1 gene demonstrates significant functions pertaining to resistance against tribenuron-methyl. However, the current data suggest that this novel metabolic gene (DsUGT84A1) may not confer cross-resistance among various ALS-inhibiting herbicides. In this respect, the TSR conferred by the Pro197His/Ser mutation may be responsible for cross-resistance. Additionally, antioxidant-related genes were upregulated in A. thaliana overexpressing DsUGT84A1, leading to a reduction in the toxicity level of reactive oxygen species (ROS). Notably, this study identifies and functionally characterizes the UGT gene DsUGT84A1 related to herbicide resistance in broadleaf weeds. This contributes to the understanding of herbicide resistance mechanisms, especially highlighting the role of UGT genes, and enhances the current understanding of resistance evolution in weeds.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative condition characterized by rapid degeneration of motoneurons (MNs), leading to progressive muscle atrophy and, ultimately, mortality within a few years of diagnosis. Although the precise mechanisms initiating MN degeneration are not fully understood, the involvement of non-neuronal cells, including microglia, in ALS pathophysiology is increasingly recognized. Mesenchymal stromal cell (MSC)-based therapies have emerged as a promising avenue for ALS treatment, yet clinical outcomes remain variable, underscoring the necessity for additional pre-clinical investigations. This study evaluated the therapeutic potential of human MSCs derived from Wharton's jelly (WJMSC) in the female SOD1[G93A] mouse model of ALS. Our results indicated that intravenous administration of WJMSC during the presymptomatic phase of the disease notably delayed the onset of motor deficits and extended the lifespan. This functional benefit was associated with the preservation of MNs in the cervical spinal cord. In the lumbar spinal cord, we did not observe MN neuroprotection, but we noted a temporary increase in microgliosis following WJMSC treatment. Our results supported the therapeutic benefits of human MSC in ALS, while also highlighting the differential responses of spinal-cord regions to the treatment during the disease progression. This study underscores the importance of targeting specific disease stages and regions for MSC therapy in ALS, paving the way for refined and potentially more effective therapeutic strategies.},

abstract = {BACKGROUND: Chronic anastomotic leakage (AL) is the most common cause of pouch failure after restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis. This study investigated factors associated with AL and successful salvage of leaking anastomoses after ileoanal pouch surgery.

METHOD: This multicentre retrospective cohort study included patients aged ≥ 18 years with ulcerative colitis or unclassified inflammatory bowel disease who underwent ileoanal pouch surgery between 2016 and 2021 in six European centres, with a > 12-month follow-up. The primary outcome was AL rate. Secondary outcomes included factors associated with AL occurrence, timing of AL diagnosis (early (< 21 days) versus late), AL management, AL salvage rate, and stoma-free survival.

RESULTS: Overall, 411 patients were included, of whom 13.6% (56) had a diagnosed AL. The rate of AL was significantly higher in low-volume (less than ten procedures annually) centres (28.0% versus 12.7%; P = 0.031). Of the 56 ALs, 44 were diagnosed as early leaks and 12 were diagnosed as late leaks. A three-stage approach was associated with late diagnosis and treatment. AL was managed using various techniques, including diverting ileostomy, antibiotics, and drainage. The overall AL salvage rate was 85.4%, but increased to 92% when diagnosed and treated early (compared with 60% when diagnosed and treated late; P = 0.010). Successful AL salvage was associated with long-term stoma-free status (P = 0.002). The median follow-up was 3.8 years (range 1.0-8.1 years). The long-term stoma-free rate was 95.5% in patients with AL diagnosed and treated early, but only 41.7% when diagnosed and treated late (P < 0.001).

CONCLUSION: Early diagnosis and treatment of AL diminishes the negative effect of AL after ileoanal pouch surgery. Proactive anastomotic assessment enable early diagnosis and management, especially in patients undergoing a three-stage approach.},

abstract = {Neurodegenerative diseases are a group of disorders characterized by the progressive deterioration of the structure and function of central nervous system neurons and include, among others, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), Parkinson's (PD), Alzheimer's (AD), and Huntington's (HD) diseases. And while all these diseases seem to have different genetic and environmental components, growing evidence shows that they share common underlying pathological features such as increased neuroinflammation and excessive oxidative stress. RAGE, the receptor for advanced glycation end-products, is a signal transduction receptor, and its activation triggers an increase in proinflammatory molecules, oxidative stressors, and cytokines. Diaph1, protein diaphanous homolog 1, is an actin modulator and an intracellular ligand of RAGE. Studies demonstrated that RAGE and Diaph1 act together, and their downstream signaling pathways play a role in neurodegeneration. Here, based on current evidence and our own research, we provide an overview of the RAGE-Diaph1 signaling and discuss the therapeutic potential of targeted therapy aimed at RAGE-Diaph1 signaling inhibition in the prevention and treatment of neurodegenerative diseases.},

abstract = {INTRODUCTION: The increasing prevalence of life-threatening neurological diseases raises the need for neuropalliative care. Setting up neurological palliative outpatient clinics is one way of addressing this need. This study aims to describe the patient clientele of a neurological palliative outpatient clinic and the spectrum of necessary treatments and interventions.

METHODS: In this longitudinal analysis, clinical routine data from a single centre were collected retrospectively from adult patients. The patient characteristics related to disease and treatment were evaluated descriptively. Factors influencing the need for ventilation were modelled in a logistic regression. The required treatment effort was modelled with a zero-inflated Beta regression. Results were reported as odds ratios with 95% confidence intervals (CIs).

RESULTS: Two hundred and thirty-two patients were included in the study. Ninety-one patients were women, 141 were men, and the mean age was 55.42 years. Neuropalliative patients represented diagnoses such as amyotrophic lateral sclerosis (ALS) (n = 81), ischemic stroke (n = 15), intracerebral haemorrhage (n = 15), Duchenne muscular dystrophy (n = 12), or craniocerebral trauma (n = 10). Palliative care counselling was the most common intervention for patients (n = 203), their close relatives (n = 177), and their nursing services (n = 75). Respiratory therapy (n = 188), speech and language therapy (n = 145), and physiotherapy (n = 143) were also frequently applied interventions. Sixty patients received botulinum toxin A treatment for hypersalivation, and 32 for spasticity. The odds of needing invasive ventilation increased by 3.7 (CI 1.7-7.8), and the need for mechanical insufflation-exsufflation increased by 2.2 (CI 1.1-4.3) in patients previously discharged from early neurological-neurosurgical rehabilitation. Prior intensive care treatment increased the odds of invasive ventilation by 5.1 (CI 2.2-11.5) and the use of mechanical insufflation-exsufflation by 2.3 (CI 1.1-4.8).

CONCLUSION: Neuropalliative outpatient clinics demand a wide range of diagnostic measures and interventions as well as a multidisciplinary approach. Further research is necessary to investigate the relation between diagnosis and treatment needs.

These diseases present major challenges to global health due to incurable or extremely difficult to treat, imposing a heavy burden on society and families. Stem cell therapy, as a novel promising approach for treating various neurological diseases, harnesses the regenerative potential of stem cells to repair damaged neural tissues and circuits, and has become the only hope for patients to recover their health or delay the deterioration of disease symptoms. In recent years, researchers have successfully generated neurons from multiple types of stem cells, and good curative effects have been achieved in their animal models and in clinical trials. This comprehensive review elaborates on the relevant content of stem cell biology, focuses on conducting an in-depth analysis of the current application status of various stem cells in major neurodegenerative and neuroimmune diseases including MS, AD, PD and ALS, kindling the hope for the development of stem cell-based cell therapies in neurological diseases.},

abstract = {BACKGROUND: Neurofilaments are key axonal proteins, with neurofilament light (NfL) and heavy (NfH) chain recognised as promising biomarkers for neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). However, neurofilament medium chain (NfM) remained previously underexplored due to a lack of quantitative assays. In this study, we developed a sensitive immunoassay to measure NfM in cerebrospinal fluid (CSF) and analysed its levels in ALS, Alzheimer's disease (AD), frontotemporal dementia (FTD), and Lewy body dementia (LBD). Correlations among neurofilaments and their diagnostic performance were also evaluated.

METHODS: In this study CSF levels of three neurofilament proteins were measured in 305 participants, including patients with ALS (n = 91), AD (n = 59), FTD (n = 38), LBD (n = 18), non-neurodegenerative controls (CTRL, n = 51), and 48 individuals initially evaluated for ALS but ultimately diagnosed with other conditions (CTRL.DD). NfM levels were quantified using a homemade sandwich ELISA, while NfL and NfH were measured using commercialised Ella cartridges.

FINDINGS: All three neurofilaments were significantly elevated in ALS compared to CTRL and CTRL.DD groups (p < 0.0001 for both), with NfM and NfL also increased in FTD (p < 0.0001 for both) and AD (NfM, p < 0.0001; NfL, p = 0.0001) compared to CTRL. NfH demonstrated the greatest distinction between ALS and FTD (p < 0.0001). Strong correlations were observed among neurofilament subunits, particularly between NfM and NfL (r = 0.93, 95% CI: 0.91-0.94, p < 0.0001). All neurofilaments effectively distinguished ALS from CTRL and CTRL.DD, with AUC values ranging from 0.92 to 0.99. NfM and NfL showed high accuracy in differentiating AD (NfM, AUC: 0.91; NfL, AUC: 0.89) and FTD (NfM, AUC: 0.91; NfL, AUC: 0.92) from CTRL, while NfH best separated ALS from FTD (AUC: 0.96).

INTERPRETATION: This study provides a quantitative comparison of NfM with NfL and NfH in a neurodegenerative cohort, highlighting its potential diagnostic value. Further research with larger cohorts, longitudinal studies, and investigations into neurofilament distribution in different compartments is needed to clarify the distinct roles of NfM, NfL, and NfH in the diagnosis and treatment of neurological diseases.

The objective of our study was to describe the real-world clinical experience with PB and TURSO at one ALS clinic.

METHODS: This was a retrospective chart review of all ALS patients receiving a PB and TURSO prescription at the Massachusetts General Hospital ALS Clinic between October 1, 2022, and September 30, 2023. Data were extracted from patients' electronical medical records up to December 31, 2023.

RESULTS: A total of 441 ALS patients received a PB and TURSO prescription, with 329 (75%) initiating the medication. The average length of treatment was 285 days, and the rate of drug discontinuation during the study period was 41% (N=135). The most common reason for drug discontinuation was side effects (N=93, 69%), with the most common being gastrointestinal issues (N=69). No hospitalizations, deaths, or serious adverse events were considered related to treatment with PB and TURSO.

DISCUSSION: Experience in real-world clinical settings can help supplement trial data with information on the drug performance at various stages of disease progression. Adverse events impacted treatment persistence in routine clinical practice, underscoring the need for vigilant monitoring and tailored supportive interventions to optimize treatment adherence.},

We report the case of a woman whose treating neurologist determined, eight months after symptom onset, that her presentation was most consistent with bulbar-onset ALS. At 16 months, she began receiving intermittent pelvis-stabilized axial spinal traction (PSAST) as a supportive intervention. Remarkably, over the subsequent 21 months, she maintained oral intake and preserved respiratory function, an outcome atypical of the expected trajectory of bulbar-onset ALS. While this single case relies on provider reports for diagnostic confirmation, it raises the hypothesis that axial spinal traction may help sustain bulbar and respiratory function in ALS. Given the lack of effective treatment options, we present this case to raise awareness of a potential supportive approach that warrants further investigation.},

Although previous studies have explored its molecular structure, pharmacological effects, and clinical applications, a comprehensive bibliometric analysis of its research trends and future directions remains lacking.

METHODS: This study employed bibliometric methods to analyze edaravone-related publications from 2000 to 2024, using the Web of Science Core Collection database. The analysis examined publication trends; contributions by countries, institutions, and authors; and keyword clustering. Data visualization tools, such as CiteSpace and VOSviewer, were utilized to identify research clusters and emerging trends in edaravone research.

RESULTS: The findings revealed a significant increase in edaravone-related publications, with China, Japan, and the United States as the leading contributors. Notable researchers, including Abe K and Yoshino H, have made substantial contributions to this field. Four major research clusters were identified: free radical scavenging, cerebral infarction, amyotrophic lateral sclerosis, and oxidative stress. Emerging trends suggest a growing interest in edaravone dexbornel for acute ischemic stroke treatment, as well as its potential applications in blood-brain barrier interactions and Alzheimer's disease.

CONCLUSION: This bibliometric analysis highlights the growing interest in edaravone and its potential clinical application, particularly in neuroprotection. While this study provides valuable insights into current research trends, future studies should incorporate a broader range of sources and languages to obtain a more comprehensive understanding of the impact and scope of edaravone.},

abstract = {Obesity is associated with impaired angiogenesis and poor recovery following myocardial infarction (MI), yet the underlying molecular mechanisms remain poorly defined. The transient receptor potential cation channel subfamily C member 5 (TRPC5) is known to regulate angiogenesis, but its role in the context of obesity-related MI is unclear. Here, we show that TRPC5 expression is downregulated in obese mice hearts following MI, resulting in compromised angiogenic function. Riluzole, an FDA-approved drug for amyotrophic lateral sclerosis, activates TRPC5 and restores the migration, sprouting, and tube formation function of coronary artery endothelial cells isolated from diet-induced obese (DIO) MI mice. In obese mice, riluzole enhances post-MI neovascularization, reduces infarct size, and improves cardiac function. Notably, TRPC5-mediated angiogenesis requires aquaporin-1 (AQP1), whose expression is regulated by TRPC5 via the nuclear factor of activated T cells 3 (NFATc3) transcription factor. Silencing AQP1 abolishes the pro-angiogenic effects of TRPC5 activation, establishing AQP1 as a critical downstream effector. In conclusion, our data provide evidence that the TRPC5-NFATc3-AQP1 pathway is essential for post-MI angiogenesis in obesity and support riluzole as a promising therapeutic approach to enhance angiogenesis in obese individuals following MI.},

NF-κB proteins regulate cellular biological activity by binding to promoter regions in the nucleus and transcribing various protein-coding genes. Emerging evidence indicates that NF-κB plays a pivotal role in driving key hallmarks of NDD progression, including neuroinflammation, oxidative stress, mitochondrial dysfunction, and dysregulation of the cell cycle. Natural products from Chinese medicine exert modulatory effects on NF-κB signaling through diverse pharmacological mechanisms, ultimately improving cognitive and motor impairments in preclinical NDDs models. The pleiotropic nature of natural products derived from traditional Chinese medicine (TCM)-which operate through subunit-specific modulation of NF-κB-underscores their potential as next-generation therapeutics. Investigating the intricate regulation of NF-κB by natural products from Chinese medicine will not only enrich our understanding of the pathogenesis of NDDs but also establish a theoretical foundation for the development of new therapeutic drugs for NDDs, providing innovative strategies for prevention and treatment.},

The results of whole-plant bioassay experiments revealed that 15 populations presented different levels of resistance to penoxsulam. The Trp-574-Leu mutation was detected in ten resistant populations, and the Pro-197-Leu mutation was detected in one resistant population. Additionally, the in vitro ALS activity in resistant populations (18-ETF, 18-WJJ, and 18-WMJ) was 51.28-, 5.51-, and 8.46-fold greater than that in the susceptible population. The ALS from these resistant populations requires a much higher penoxsulam concentration for activity inhibition. ALS gene expression in three resistant populations (18-ETF, 18-WJJ, and 18-WMJ) was 1.53-, 1.58-, and 1.41-fold greater than that in the susceptible population 18-NJ before penoxsulam treatment.

In their recent work, Kim et al utilized data from the National Cancer Database to explore whether adding chemotherapy to surgical intervention could improve survival outcomes for patients diagnosed with stage II gallbladder cancer. The use of adjuvant chemotherapy following curative surgery in this patient population has been a long-standing source of debate. Historically, the lack of clear guidelines for managing stage II gallbladder cancer has resulted in inconsistent, sometimes contradictory findings from various studies regarding the effectiveness of postoperative chemotherapy. Consequently, many clinicians have relied on studies involving other biliary tract cancers to justify the routine use of prophylactic chemotherapy after surgery, aiming to minimize recurrence risk. Given the rarity, high mortality rate, and the small sample sizes typical in gallbladder cancer studies, Kim et al's contribution represents a significant and commendable effort to address these challenges. Kim et al designed a retrospective cohort study with well-defined inclusion criteria and clear treatment classifications. Notably, their findings suggested that in stage II gallbladder cancer, adjuvant chemotherapy did not yield a meaningful survival benefit over surgery alone. These results therefore casted doubt on the routine practice of administering chemotherapy to all patients postoperatively, prompted clinicians to reconsider their approach. Furthermore, this controversy directly influences clinical decisionmaking and guideline recommendations, as uncertainty regarding the benefit of adjuvant chemotherapy may lead to heterogeneous practices across different institutions and regions. This article critically assessed the research design, methodology, and clinical implications of the study by Kim et al. It also provided an in-depth exploration of the broader question regarding the appropriateness of adjuvant chemotherapy following surgery for stage II gallbladder cancer, highlighting the necessity of rigorous study designs to produce reliable evidence.},

Additionally, transhiatal distal esophageal resections operated during this period were included. Drainage fluid was collected on postoperative days (PODs) 1-4 with consecutive blood gas analysis. Test quality was determined by the area under the curve (AUC) of the receiver operating characteristic curve (ROC). Results: In total, 40 patients were included, with 17 developing AL. There were no significant differences in gender, age, BMI or oncological treatment. The 30-day morbidity rate was 65.0%. The study was restricted to events in the first 12 days. While lactate value in drainage fluid differed significantly from POD 3 onwards in the two groups, serum CRP remained without significant differences. We developed the LacCRP score (CRP/30 + lactate/2). The AUC on POD 3 was 0.96, with a sensitivity and specificity of 100% and 75%, respectively. An estimator of 1.08 was found in multivariate analysis: one-point increase in the LacCRP score increases AL probability by 8%. Conclusions: This study demonstrates that postoperative lactate determinations in drainage fluid can predict AL after esophageal resection, and its combination with serum CRP results in a reliable LacCRP score.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive loss of motor neurons. Although genetic and environmental factors are established contributors, recent research has highlighted the critical role of the gut-brain axis (GBA) in ALS pathogenesis. The GBA is a bidirectional communication network involving neural, immune, and endocrine pathways that connect the gut microbiota with the central nervous system. Dysbiosis in ALS disrupts this axis, leading to increased intestinal permeability, neuroinflammation, and excitotoxicity. Notably, reductions in butyrate-producing bacteria, alterations in microbial metabolites, and enhanced NLRP3 inflammasome activation have been observed in patients with ALS. These changes may precede motor symptoms, suggesting a potential causative role. Interventions targeting the microbiome, such as dietary modulation, have shown promise in delaying disease onset and reducing inflammation. However, the clinical evidence remains limited. Given that gut dysbiosis may precede neurological symptoms, microbiota-targeted therapies offer a novel and potentially modifiable approach to ALS treatment. Understanding the role of GBA in ALS will open new avenues for early diagnosis and intervention. Further clinical trials are required to clarify the causal links and evaluate the efficacy of microbiome-based interventions. Understanding the brain-gut-microbiota axis in ALS could lead to new diagnostic biomarkers and therapeutic strategies.},

These disorders involve progressive neuronal loss and cognitive decline, with incompletely elucidated underlying mechanisms. Chronic neuroinflammation is increasingly recognized as a critical contributor to disease progression. The brain's resident immune cells, microglia, are central to this inflammatory response. When overactivated, microglia and other immune cells, such as peripheral macrophages, can exacerbate inflammation and accelerate disease development. Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) is a transmembrane receptor of the immunoglobulin superfamily that demonstrates high expression on microglia in the central nervous system. TREM2 serves a vital role in regulating phagocytosis, synaptic pruning, and energy metabolism. This review examines the functions of TREM2 in neurodegenerative diseases and its potential as a therapeutic target, aiming to inform future treatment strategies.},

abstract = {BACKGROUND: In amyotrophic lateral sclerosis (ALS), dextromethorphan/quinidine (DMQ) has been reported to reduce bulbar symptoms, including dysarthria and dysphagia. However, data on patients' perceptions of DMQ treatment are limited.

METHODS: Data on DMQ treatment were collected from 1065 ALS patients treated at 13 ALS centers between 10-2015 and 06-2025. Patient-reported outcome measures (PROM) of 179 participants were remotely assessed via the "ALS App". PROM included the self-explanatory version of the ALS Functional Rating Scale (ALSFRS-R-SE), the Net Promoter Score (NPS); and Treatment Satisfaction Questionnaire for Medication (TSQM-9).

RESULTS: Mean disease duration was 29.3 months (SD 38.1). ALS progression before treatment was 0.82 points/month (ALSFRS-R). Mean DMQ treatment duration was 8.4 months (SD 10.8), including 35.2% (n = 374) of shorter (<3 months), 35.3% (n = 375) of longer (3-9 months), and 29.5% (n = 313) of very long DMQ treatment (>9 months). Patients' recommendation (n = 178) was positive (NPS: +23) with higher scores after very long DMQ treatment (NPS +37) compared to longer (NPS +15) and shorter treatment (NPS +7.5), respectively. TSQM-9 scores (n = 163) demonstrated high satisfaction for effectiveness 60.0 (SD 25.9), convenience 73.8 (SD 18.2), and global satisfaction 63.4 (SD 29.8).

INTERPRETATION: The positive perception in PROM underscores the value of DMQ as an individualized treatment option for bulbar symptoms in ALS. However, shortage of clinical data, online assessment, and selection biases are among the limitations of this study that need to be addressed in further investigations.},

Far from being a secondary consequence of neuronal damage, inflammatory processes (mediated by microglia, astrocytes, peripheral immune cells, and associated molecular mediators) actively shape disease onset, progression, and symptomatology. This review synthesizes current knowledge on the cellular and molecular mechanisms that govern neuroinflammatory responses, emphasizing both shared and disease-specific pathways. We examine how innate and adaptive immune interactions contribute to neuronal vulnerability and neurodegenerative cascades, and explore the reciprocal communication between systemic and central immune compartments. Particular attention is given to emerging therapeutic strategies aimed at modulating neuroinflammation, including immunomodulatory drugs, glial-targeted interventions, and novel delivery platforms. By integrating findings across disciplines and disease models, we outline key translational challenges and propose future directions to harness neuroinflammation as a therapeutic target in the era of precision medicine. Ultimately, a deeper understanding of neuroimmune dynamics holds promise for redefining both the diagnosis and treatment of neurodegenerative disorders.},

abstract = {BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by oxidative stress and progressive motor neuron degeneration. This study evaluates the potential neuroprotective effects of caffeine in the Wobbler mouse, an established model of ALS.

METHODS: Wobbler mice received caffeine supplementation (60 mg/kg/day) via drinking water, and key parameters, including muscle strength, NAD metabolism, oxidative stress, and motor neuron morphology, were assessed at critical disease stages.

RESULTS: Caffeine delayed motor performance decline, as observed in grip strength tests during the early symptomatic phase. Histological analyses revealed that significantly fewer motor neurons were lost in caffeine-treated mice at p41, despite no changes in soma morphology. Biochemical assays demonstrated that caffeine significantly reduced ROS levels and restored NAD levels to wildtype-like values, although NMNAT2 protein expression remained unaffected. The data suggest that caffeine mitigates oxidative stress through alternative pathways, potentially involving enhanced mitochondrial function and antioxidative defenses.

CONCLUSIONS: These findings highlight the potential of caffeine as a protective agent for delaying motor neuron degeneration in ALS. Future studies should explore optimal dosing strategies, combinatorial treatment approaches, and the underlying molecular mechanisms, to enable translation of these findings to human ALS patients.},

abstract = {Pompe disease is an autosomal recessive neuromuscular disorder characterized by a deficiency of acid α-glucosidase (GAA), an enzyme responsible for lysosomal glycogen degradation in all cells. Respiratory distress is a common symptom among patients with Pompe disease resulting from weakness of primary respiratory neuromuscular units of the diaphragm and genioglossus and the motor neurons which innervate them. The only FDA approved treatment is enzyme replacement therapy (ERT) of recombinant human GAA (rhGAA) which slows the decline of motor function and extends life expectancy. However, ERT does not cross the blood-brain barrier and thus, is unable to treat the critical pathology present in motor neurons hindering long-term efficacy. In the present study, we sought to explore an alternative treatment for Pompe patients to improve breathing by improving the function of motor neurons. Therapeutic acute intermittent hypoxia (tAIH) is a non-invasive therapeutic modality which has had success in improving respiratory and non-respiratory motor function in patients with spinal cord injury, amyotrophic lateral sclerosis, multiple sclerosis, and stroke. Here, we treated adult Gaa[-/-] mice with a single, week-long tAIH protocol, followed by bi-weekly tAIH for 4 months. We report three critical findings: (1) both short and long-term tAIH therapy modestly improve breathing in Gaa[-/-] mice; (2) long-term tAIH-therapy in WT mice moderately elevates breathing responses; and (3) these trending improvements to respiration in Gaa[-/-] may be related to changes in chemoreflex activation, reduced kyphosis, and improved overlap of acetylcholine receptors and phrenic motor neuron axon terminals in the diaphragm muscle.},

abstract = {BACKGROUND: The progressive legalization and widespread use of cannabis has led to its use as a treatment for certain neuropsychiatric disorders. Traditional epidemiological studies suggest that cannabis use has an effect on some neurocognitive aspects. However, it is unclear whether cannabis use is causally related to common neuropsychiatric disorders. The present study was conducted to illustrate the causal relationships of genetically predicted cannabis use with common neuropsychiatric disorders.

METHODS: We used a two-sample Mendelian randomization method using genome-wide association study (GWAS) summary statistics obtained from publicly available databases on lifetime cannabis use and 10 neuropsychiatric disorders, including multiple sclerosis (MS), Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), autism spectrum disorder (ASD), epilepsy, generalized epilepsy, focal epilepsy, migraine, migraine with aura, migraine without aura, schizophrenia (SCZ), anorexia nervosa (AN), attention-deficit/hyperactivity disorder (ADHD), and Parkinson's disease (PD) were studied with a two-sample Mendelian randomization method for GWAS summary statistics. The inverse variance weighted (IVW) method was used as the main analysis model.

RESULTS: Our study suggests that lifetime cannabis use is associated with an increased risk of developing PD (odds ratio (OR) = 1.782; 95% CI 1.032-3.075; p = 0.038) and an increased risk of ADHD in female participants (OR = 1.650; 95% CI 1.051-2.590; p = 0.029).

CONCLUSIONS: Cannabis intake may cause adverse effects relating to certain neuropsychiatric disorders. Therefore, special attention should be paid to the side effects of addictive drugs during clinical treatment to avoid harmful effects on the brain and neurocognition.},

abstract = {Neuromuscular diseases are often accompanied by various types of sleep-related breathing disorders, which can exacerbate the underlying condition and are associated with a poor prognosis. Early identification is essential, and interventions such as non-invasive ventilation, oxygen therapy, and respiratory rehabilitation should be initiated promptly to mitigate disease progression and improve outcomes. Nevertheless, the rates of missed and misdiagnosed cases remain common in clinical practice. Currently, there are no standardized guidelines for the diagnosis and treatment of sleep-disordered breathing related to neuromuscular diseases in China. Therefore, based on the latest domestic and international research progress, and combined with domestic clinical diagnosis and treatment experience, the Sleep Disorder Group of Chinese Thoracic Society has brought together multidisciplinary experts to develop this expert consensus. This consensus provides a comprehensive overview of the epidemiology, clinical manifestations, diagnostic approaches, assessment strategies, and treatment of sleep-disordered breathing related to neuromuscular diseases. It formulates evidence-based recommendations to guide clinical practice, with the aim of providing standardized recommendations for their diagnosis and management.Statement 1: The neuromuscular disorders that are most frequently associated with sleep-disordered breathing include: myasthenia gravis (1A), amyotrophic lateral sclerosis (2B), post-polio syndrome (2B), myotonic dystrophy (2B), peripheral neuropathies (2C), and metabolic myopathies, among other neuromuscular conditions.Statement 2: Patients with neuromuscular disorders frequently develop multiple types of sleep-disordered breathing concurrently or sequentially, with obstructive sleep apnea (OSA) being the most prevalent manifestation. Distinct clinical manifestations of OSA are observed across different neuromuscular disease subtypes (1A).Statement 3: Neuromuscular disorders predispose to central sleep apnea (CSA), with clinical manifestations varying significantly across disease subtypes, stages of progression, and severity levels (1A).Recommendation 1: In patients with neuromuscular disorders exhibiting progressive hypercapnia or worsening hypoxemia, clinicians should investigate potential comorbid nocturnal alveolar hypoventilation and/or sleep-associated hypoxemia (1A).Recommendation 2: When sleep-disordered breathing is suspected, patients with neuromuscular disorders should be evaluated for symptoms of sleep-disordered breathing. Meanwhile, sleep monitoring, non-invasive CO2 monitoring, and related examinations should be actively performed according to the actual situation (1A). A polysomnography should be performed when there is a high clinical suspicion of sleep-disordered breathing but a negative result on a portable sleep monitor (1A).Recommendation 3: (1) Noninvasive positive pressure ventilation (NPPV) titration under polysomnography is the standard method to determine the effective treatment parameters for neuromuscular diseases with sleep-disordered breathing (1A). (2) Positive airway pressure titration in OSA patients with neuromuscular diseases should follow American Academy of Sleep Medicine (AASM) guidelines (1A). (3) For neuromuscular disorders with CSA or Cheyne-Stokes respiration, bi-level positive airway pressure (BPAP) with ST pattern is recommended (1A); When BPAP is not tolerated or accompanied by severe Cheyne-Stokes respiratory and heart failure in patients, adaptive support ventilation (ASV) should be used (2B). (4) Patients with neuromuscular disease and sleep-related alveolar hypoventilation should be treated with BPAP or variable assurance pressure support (VAPS) (1A). (5) BPAP with alternate frequency is preferred for neuromuscular disorders with "pseudo-central events" (1A).Recommendation 4: Oxygen therapy alone is not recommended for neuromuscular disease patients combined with sleep-disordered breathing (2D). Oxygen therapy with monitoring of CO2 level is recommended when non-invasive ventilation therapy cannot effectively correct hypoxemia (2C). Diaphragmatic pacing should not be routinely used in amyotrophic lateral sclerosis patients with respiratory failure (2B). Transvenous phrenic nerve stimulation is not currently applied to CSA caused by neuromuscular disorders (2D). Respiratory rehabilitation may improve respiratory muscle strength in a subset of patients with neuromuscular disorders (2B). Protiline can be used for REM-associated alveolar hypoventilation, and daytime sleepiness could be addressed with methylphenidate and modafinil (2C).Recommendation 5: Neuromuscular disease combined with sleep-disordered breathing is a chronic disease requiring patient-centered, individualized education and long-term follow-up management (1A).},

We report on a patient with a primary, non-metastatic MCC on the left eyelid and amyotrophic lateral sclerosis (ALS). Due to ALS, the patient's communication was limited to eye movement and blinking. Complete resection or definitive radiotherapy of the tumor while preserving the function of the eye muscles was not possible. No prior data was available for patients with ALS under ICI therapy. In agreement with the patient and his family, a monotherapy with avelumab, a programmed death ligand 1 (PD-L1) inhibitor, was initiated. This led to a complete remission of the tumor with a progression-free survival of over 24 months and importantly no deterioration of the ALS.},

Diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease precipitate cognitive, motor, and behavioral deficits. Parallelly, spinal cord injuries produce sensory and motor deficits, which are burdensome psychologically, socially, and economically. Current management strategies focus only on symptomatic relief, with no definitive cure. Stem cells have been explored for regenerative therapy. This review focuses on developments, limitations, and future potential of stem cell therapy. Stem cells affect the central nervous system via neuroprotective mechanisms, immunomodulatory effects, and mitigation of oxidative stress. The clinical implications of stem cell therapy in treating neurodegenerative diseases and SCI are debatable due to varied outcomes. Challenges related to sample size, long-term follow-up, and assessment of adverse effects should be mitigated in future research. Researchers are currently exploring optimal stem cell types along with various transplantation strategies. Biomaterials integrated with stem cells are a novel approach for treating neurodegenerative diseases and spinal cord injuries. Certain genetic modifications have shown improved results. Screening patients to ascertain better responses to therapy has proven to be a challenge. Other complications include graft vs. host reaction and degeneration of transplanted neurons due to pathogenesis and tumorigenesis. However, the majority of the potential stem cell therapeutic avenues are in the preclinical stage and are being tested on animal models. Guidelines pertaining to ethical concerns and regulatory frameworks need to be established to unfold the full potential of stem cell therapy in the clinical setting. Recent advances also show an increased need to formulate patient-specific approaches to treatment, ranging from stem cell selection to the technique of transplantation. Ongoing clinical trials can address the current challenges and leverage emerging technologies, leading to definitive treatments for neurodegenerative diseases and spinal cord injuries.},

For decades, the use of cell therapy in treatment of neurorehabilitation conditions have been explored to complement the current, mainstay treatment options; however, a consensus for standardization of the cell therapy and its efficacy has not been reached in the medical community. This study aims to provide a comparative review on the very topic of cell therapy use in neurorehabilitation conditions in an attempt to bridge the gap in knowledge.

METHODS: Studies were searched from the PubMed database published from 2014 to 2024 employing the terms including but not exclusive to "spinal cord injury," "brain injury," "amyotrophic lateral sclerosis," "regenerative medicine," "cell therapy," and "stem cell." Following the PRISMA 2020 statement, the studies were screened, included, and excluded. Thirty three studies were identified and selected for this review.

RESULTS: Countless researchers investigated the efficacy of various stem cell products for the treatment of numerous neurotraumatic conditions, such as spinal cord injury, traumatic brain injury, and neurodegenerative conditions such as amyotrophic lateral sclerosis. The recent decade of studies suggest that in neurotraumatic conditions, bone-marrow-derived and neural stem cells can be effective, and in neurodegenerative conditions, such as ALS, mesenchymal and neural stem cells can be efficacious.

CONCLUSION: Emerging data from the latest research is encouraging to the patients suffering from neurotraumatic and neurodegenerative conditions, which present themselves as a need for further studies with improved standardization in study design, including cell source specification, differentiation and culture method, and outcome measures to ensure a wide applicability.},

We discovered a small molecule NLRP3 inflammasome inhibitor, NT-0527 (11), and extensively profiled this to reveal a highly potent, selective and brain penetrant compound. This was shown to be orally bioavailable, efficacious in an in vivo model of inflammation, and with good developability characteristics.

First-line therapy combines antiretroviral therapy (ART) with chemo-therapy, achieving complete remission rates of 60-70% for DLBCL using R-EPOCH and 50-60% for BL with CODOX-M/IVAC. Relapsed/refractory cases show durable responses to CD19-CAR-T therapy; however, only 10% of HAL patients are enrolled in pivotal immunotherapy tri-als. Severe immunosuppression necessitates PET-CT-guided de-escalation and nanoparticle-based drug delivery systems to minimize toxicity. Emerging strategies include PD-1 inhibitors and broad-spectrum antivirals targeting HIV reservoirs, underscoring the need for precision med-icine that integrates tumor genomics and viral dynamics.},

abstract = {Abnormal accumulation of TAR DNA-binding protein-43 (TDP-43) is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Small interfering RNAs (siRNAs) targeting TDP-43 offer potential therapeutic strategies for these diseases. However, efficient and safe delivery of siRNAs to the central nervous system (CNS) remains a critical challenge. Here, we present a synthetic biology-based approach that leverages endogenous small RNA processing machinery to self-assemble siRNA-encapsulating small extracellular vesicles (sEVs) and utilizes the host's natural circulatory system to transport siRNAs. Specifically, we engineered liver cells to express and package TDP-43-targeting siRNAs into rabies virus glycoprotein (RVG)-tagged sEVs, which are released into circulation and cross the blood-brain barrier to deliver siRNAs to the CNS. In a mouse model of TDP-43 pathology induced by stereotactic injection of mutant TDP-43 (M337V) virus, treatment with in vivo self-assembled TDP-43 siRNAs (IVSA-siR-TDP43) effectively reduced TDP-43 accumulation, leading to significant improvements in motor function and neuropathology. Additionally, an adeno-associated virus (AAV)-based delivery system was utilized to produce IVSA-siR-TDP43, demonstrating sustained therapeutic effects in TDP-43-associated neurodegeneration. These findings highlight a novel, effective, and minimally invasive gene therapy platform for addressing TDP-43 pathology in ALS and FTLD, offering a promising avenue for future clinical applications.},

He presented with complaints of slurred speech, hearing impairment, generalised weakness of limbs, weakened grip to hold objects in hand, difficulty to walk with normal speed, frequent dizzy feeling while walking, severe fatigue, increased anger, heaviness of head, depression, anxiety, decreased memory and headache for 1 year. When he consulted conventional medicine, in Magnetic Resonance Imaging (MRI) of brain, only 'Partial empty sella' and age related mild cerebral atrophy was detected and the patient was diagnosed PBP clinically. They prescribed Riluzole 50 mg tablet twice a day and Fluoxetine 10mg capsules at night time for 3 months, but obtained no relief for symptoms and consulted this Out Patient Department (OPD). In Ayurvedic parlance, PBP resembles conditions like Kaphavruta vata. In this patient, Pittavritavata symptoms like bhrama (∼dizziness) was also present in increased severity. Diagnosis was done with the aid of Gold Coast diagnostic criteria. Internal and external medications with properties alleviating avarana (∼occlusion) of vata by kapha and pitta, shodhana (∼expelling the aggravated doshas and cleanses the body internally), rejuvenating (Rasayana) properties, for overall strengthening of nervous system and musculoskeletal system, enhancing balance and coordination, improving speech and memory were used. The assessment was done before and after the treatment by 'Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). The score before and after the treatment was 35 and 45 respectively out of 48. The treatment helped to increase the quality of life exceptionally as symptomatic relief was obtained. As it is a devastating disorder with poor prognosis and most probably will lead to death, it is advisable to repeat the treatments in regular intervals, depending on the recurrence of symptoms, if any.},

This imbalance can lead to tissue and organ damage, contributing to the pathogenesis of various diseases. The nervous system, due to its high oxygen consumption, is particularly susceptible to oxidative stress. Numerous neurotoxins can induce neurotoxicity through oxidative stress, thereby contributing to the onset of neurodegenerative diseases, such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis. Furthermore, neurotoxicity can exacerbate oxidative stress by disrupting mitochondrial metabolism and impairing the activity of antioxidant enzymes, thereby intensifying neurotoxic effects. This review examines the mechanisms underlying the interaction between oxidative stress and neurotoxicity and explores strategies to mitigate neurotoxicity by reducing oxidative stress, with the aim of informing future clinical approaches for the treatment of neurodegenerative diseases.},

abstract = {Innate immune signaling pathways are hyperactivated in the central nervous system (CNS) of patients with Amyotrophic Lateral Sclerosis (ALS), as well as in preclinical models with diverse causative backgrounds including TDP-43, SOD1, and C9orf72 mutations. This raises an important question of whether these pathways are key pathogenic features of the disease, and whether therapeutic amelioration could be beneficial. Here, we systematically profile Type-I interferon (IFN)-stimulated gene (ISG) expression signatures using a non-biased approach in CNS tissue from a cohort of 36 individuals with ALS, including sporadic ALS (sALS; n=18), genetic ALS caused by (i) a C9orf72 hexanucleotide repeat expansion (C9-ALS; n=11), and (ii) a SOD1 mutation (SOD1-ALS; n=5), alongside age- and sex-matched individuals who died of a non-neurological cause (n=12). Using this deeply phenotyped cohort we have implemented targeted transcriptomic analysis and immunohistochemistry to interrogate the nature and extent of the activation of the Type-I IFN response in patients. We determined disease and genotype specific IFN signatures that correlate with clinical phenotype. Correlation analysis linked six ISGs with aggressive disease progression, as indicated by negative correlation with age at death in ALS patients. Notably, significant upregulation of ISGs was observed in C9-ALS patients, with higher ISG expression correlating with shorter disease duration. Noting that our genotype and disease specific signatures correlated with metrics of disease progression, we explored the therapeutic potential of targeting this pathway in a mouse model of ALS. Treatment with an IFN pathway inhibitor reduced IFN response markers, delayed disease progression, including motor decline, and extended survival in ALS mice. We conclude that upregulation of gene expression in the Type-I IFN pathway represents a key pathological feature of ALS and that inhibiting this pathway may provide a promising therapeutic approach for treating ALS.},

In this study, we aimed at expanding upon these findings by further evaluating its effects on upper limb (UL) functions and mood symptoms both in ALS and other neuromuscular disorders (NMDs).

METHODS: Sixty-eight patients participated in a regular 2-week occupational therapy program once a day. For three days a week, in place of the traditional treatment, the AAT group (N = 34) performed a session in interaction with the therapy dog. Outcome measures included hand grip strength, manual dexterity, and mood symptoms. Differences between baseline and post-treatment values were assessed using the Wilcoxon Signed-Rank Test, and one-way analysis of covariance was used to examine between-group differences in post-treatment values, adjusting for baseline measurements.

RESULTS: Both groups improved in hand grip strength (p = 0.004-0.03), whereas mood symptoms improved exclusively in the AAT group (p = 0.0003-0.03). Post-treatment values were significantly better in the AAT group (p = 0.01-0.03). When ALS patients were analyzed separately, the improvement of hand grip strength and mood symptoms was observed only in the AAT group (p = 0.001-0.04), which accordingly showed better post-treatment values (p = 0.0007-0.05).

DISCUSSION: Our findings indicate that AAT has greater beneficial effects than traditional treatments on UL strength and mood symptoms. These findings have the potential to facilitate more effective rehabilitation strategies both in ALS and other NMDs.},

abstract = {INTRODUCTION: Neurodegenerative disorders such as Alzheimer's, Parkinson's, and ALS are characterized by progressive neuronal dysfunction with limited therapeutic options. Recent advances in molecular biology and drug development have highlighted the therapeutic promise of precision enzyme targeting, offering novel strategies for disease modulation and symptom management.

METHODS: A comprehensive literature review spanning recent/current was conducted using PubMed, Scopus, and ScienceDirect. Studies focusing on enzyme-based targets, high-throughput screening, and molecular docking in neurodegeneration were included. Thematic synthesis was employed to categorize findings based on enzyme class, disease relevance, and therapeutic outcomes.

RESULTS: Key enzyme families such as kinases, proteases, and oxidoreductases were identified as pivotal modulators in disease progression. Emerging enzyme-targeted compounds demonstrated enhanced bioavailability, blood-brain barrier permeability, and disease-specific efficacy. Novel screening platforms and computational modeling enabled the precise selection of inhibitors, significantly improving the therapeutic index and reducing off-target effects.

DISCUSSION: Targeting enzymes implicated in neuroinflammation, oxidative stress, and protein misfolding has shown disease-modifying potential. Integrating precision drug discovery tools, such as AI-assisted modeling and enzyme kinetics, supports rational drug design. However, translational challenges persist due to variability in enzyme expression and disease heterogeneity.

CONCLUSION: Future research should focus on refining enzyme inhibitors and integrating biomarkers to facilitate personalized treatment strategies for neurodegenerative disorders. As the understanding of enzymatic roles in neurodegeneration deepens, precision enzyme-targeted drug discovery holds significant promise in transforming neurotherapeutic approaches.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by mislocalization and aggregation of proteins in motor neurons. Ataxin-2 (ATXN2), an RNA-binding protein harboring 22-polyglutamine (polyQ) repeats, is a risk factor for ALS, when its polyQ repeats are expanded to 27-33 repeats. However, the physiological function of ATXN2 beyond its role in RNA regulation, and how polyQ expansion in ATXN2 increases risk for ALS, remain unclear. We previously demonstrated that Drosophila Atx2 functions as a regulator of microtubule (MT) dynamics in motor neurons. Here, we uncover the molecular mechanism underlying Atx2-mediated MT regulation and how polyQ expansion disrupts its function, using a mixed-sex population of Drosophila as a model system. Specifically, we show that Atx2 requires its RNA-binding Lsm domain to regulate MTs. Notably, the LSM domains of human ATXN2 rescue MT phenotype in Drosophila, demonstrating an evolutionarily conserved role of ATXN2 in MT regulation. Importantly, we find that polyQ-expanded ATXN2 forms cytoplasmic aggregates and leads to excessive MT destabilization. Additionally, polyQ expansion severely impairs axon outgrowth. Finally, we identify Uncoordinated-76 (UNC-76/FEZ1) as a downstream effector of Atx2 in MT regulation and neuronal development.Significance Statement ALS is a progressive neurodegenerative disease with no effective treatment. Although polyglutamine (polyQ) expansion in the RNA-binding protein ATXN2 is a known risk factor for ALS, its mechanistic role in ALS pathogenesis has remained unclear. We demonstrate that ATXN2 regulates MT dynamics via its RNA-binding domain, and this role is evolutionarily conserved between Drosophila and humans. We further identify UNC-76/FEZ1 as a downstream effector of ATXN2 in regulating MT dynamics and neuronal development. Importantly, this study reveals how polyQ expansion in ATXN2 disrupts MT stability and axon growth, proposing a mechanism that may contribute to increased ALS risk.},

Reasons for the difficulty in finding cures for these conditions include complications in early diagnosis, progressive and irreversible neuronal damage, and the presence of the blood-brain barrier (BBB), which hinders the delivery of drugs to the affected areas of the brain. Intranasal (INL) drug administration has increasingly gained popularity among researchers for targeting neurological conditions, because of its ability to bypass the BBB. However, chronic INL administration leads to nasal mucosa irritation. Additionally, rapid mucociliary clearance, a lack of targeted drug delivery, increased enzymatic degradation, and tight junctions that obstruct drug transport limit the clinical applicability of the INL route. To overcome these challenges, a unique region in the rodent nose, known as the Grueneberg Ganglion (GG), can be considered to be a novel site for INL drug administration. GG is a small structure housed under the snout cartilage of the nasal septum, approximately 1.5 mm from the nasal opening in mice. It is directly connected to the main olfactory bulb through axons. This Perspective aims to expand knowledge on why GG may be a viable option for INL delivery to combat neurological conditions. For better understanding, we have explained the INL administration in GG, using Alzheimer's Disease and INL insulin therapy as a role model for the current review.},

OBJECTIVES: This study aimed to evaluate racial and ethnic disparities in ALS care, specifically differences in healthcare utilization, treatment patterns, and survival, within a large healthcare system.

DESIGN: This retrospective cohort study analyzed electronic health records from a large healthcare system in Texas for patients diagnosed with ALS between 2013 and 2023, examining racial and ethnic differences in treatment and outcomes.

METHODS: Patients were identified using International Classification of Diseases (ICD) codes. Baseline characteristics, including race/ethnicity and socioeconomic factors, were collected. Primary outcomes included the use of noninvasive ventilation (NIV), tracheostomy, gastrostomy, mobility aids, and ALS medications; secondary outcomes included time to diagnosis and survival. Racial and ethnic disparities were assessed using generalized linear regression and Cox proportional hazards models, adjusting for demographic and socioeconomic factors.

RESULTS: A total of 636 patients were included (74.5% Non-Hispanic White, 5.3% Non-Hispanic Black, 7.4% Hispanic, and 12.7% Other). Non-Hispanic Black patients had significantly higher tracheostomy rates than Non-Hispanic White patients (35.3% vs 8.7%; adjusted odds ratio (OR), 6.20; 95% confidence interval (CI), 2.43-15.84). Hispanic patients had lower odds of receiving riluzole (42.6% vs 61.8%; adjusted OR, 0.36; 95% CI, 0.18-0.71) and higher rates of emergency department visits (adjusted OR, 2.00; 95% CI, 1.09-3.65) and hospitalizations (adjusted OR, 2.57; 95% CI, 1.37-4.81). No significant racial or ethnic differences were observed in time to diagnosis or survival after adjustment.

CONCLUSION: Significant racial and ethnic disparities exist in ALS care, particularly in tracheostomy utilization, medication prescribing, and healthcare access. These findings underscore the need for targeted interventions to promote equitable ALS management, including provider education and improved healthcare accessibility.},

abstract = {AIM: This review provides a systematic evaluation of 94 stem cell clinical trials to treat neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease.

METHODS: Data were collected from using relevant search terms, focusing exclusively on stem cell therapy. Of the 8000+ participants in these trials, nearly 70% were enrolled in AD-related studies. Only three Phase 3 studies were conducted, and most trials were in the early phases (Phases 1 and 2). Mesenchymal stem cells, neural stem cells, induced pluripotent stem cells, and embryonic stem cells are used the most to treat neurodegenerative diseases. This review also explores the emerging fields of preclinical and clinical investigations of stem cell-derived exosome-based therapies for neurodegenerative diseases.

RESULTS: Exosomes can cross the blood-brain barrier to deliver therapeutic molecules directly to the brain, offering a less invasive alternative to stem cell transplantation. Mesenchymal stem cell-derived exosomes, in particular, have demonstrated significant potential in preclinical models by reducing neuroinflammation, oxidative stress, and promoting neuronal regeneration. Additionally, recent advances in exosome engineering, including surface modifications, therapeutic agent loading, and transgenic modifications, have improved targeting, stability, blood-brain barrier delivery, and neural cell interactions, enabling targeted and effective treatment. Exosome-based therapies are in the preliminary phases of clinical investigation, with only three clinical trials.

CONCLUSION: Given the increasing interest in exosome therapy, clinical investigations are expected to increase. This growth will be driven by ongoing advancements in exosome technology, a deeper understanding of their therapeutic potential, and escalating demand for innovative treatment strategies for neurodegenerative diseases.},

Voltage-dependent anion channel 1 is a key regulator of these processes. This review described the structure, membrane topology, and physiological function of voltage-dependent anion channel 1 in neurons and glial cells. We emphasize how it affects mitophagy, oxidative damage, and changes in mitochondrial permeability.

Furthermore, the paper examines the function of voltage-dependent anion channel 1 in astrocytic dysfunction and microglial activation, highlighting its impact on neuroinflammation. In a nutshell, we assess treatment strategies that target voltage-dependent anion channel 1, such as VBIT-4, a selective inhibitor of voltage-dependent anion channel 1 oligomerization, and newer methods, including structure-based drug design and CRISPR/Cas9 regulation. Improved knowledge of the hinter voltage-dependent anion channel 1 of the molecular mechanism may allow for new therapeutic approaches in neurodegenerative diseases.},

Neurodegenerative diseases manifest primarily as cognitive and behavioral disorders that adversely affect the lives of millions of people worldwide. Therefore, it is necessary to elucidate the mechanism of neurodegenerative diseases further and find effective new therapies. In recent years, increasing evidence has shown that the immune system plays a significant role in the pathophysiology of neurodegenerative diseases and regulates this process. The central and peripheral immune systems exert different roles in the disease progression. The development of neurodegenerative diseases is influenced by interactions between them. This review focuses on how the immune system, including microglia mediated nucleotide-binding oligomerization domainlike receptor protein 3 inflammation activation and T cell-mediated neuroinflammation, interactions with neurodegenerative diseases by modulating protein aggregation and blood-brain barrier permeability. Besides, we gave particular attention to glial cell-centered multicellular interactions and the inflammatory signaling pathway. Insight into the immune system's functions and cellular interactions is essential for progressing disease research. In addition, the functions and mechanisms of these immune cells also suggest new ideas and targets for treatment. Therefore, this review summarizes some of the existing treatment strategies for amyloid-beta, tau, neuroinflammation, α-synuclein, associated microbiota, immune modulation, and neural injury repair. In addition, this review summarizes and compares animal models of different common neurodegenerative diseases and clinical research progress.

abstract = {In recent years, an increasing number of researchers have become interested in the bidirectional communication between the gut microbiota and the central nervous system. This communication occurs through the microbiota-gut-brain axis. As people age, the composition of the gut microbiota undergoes considerable changes, which are now known to play an important role in the development of many neurodegenerative diseases. This review aims to investigate the complex bidirectional signaling pathways between the gut and the brain. It summarizes the latest research findings on how the gut microbiota and its metabolites play critical roles in regulating inflammation, maintaining gut health, and influencing the development of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. The review also analyzes the current clinical applications of gut microbiota-based treatments for neurological disorders, including fecal microbiota transplantation, probiotics, and prebiotics. Many studies show that the gut microbiota affects the brain in several ways. For example, it can produce substances such as short-chain fatty acids and activate inflammatory pathways. Studies involving animals and laboratory models have demonstrated that adjusting the gut microbiota can help improve behavior and reduce neurological problems. Recent metagenomic and metabolomics studies have shown that the microbiota plays a crucial role in maintaining the organism's health. Microorganisms primarily colonize the gut and are involved in host nutrient metabolism, maintaining the structural integrity of the intestine, preserving the intestinal mucosal barrier, and modulating the immune system. The gut microbiota communicates with the brain through a bidirectional microbiota-gut-brain axis. The composition of the gut flora changes considerably with age, and ecological dysregulation has been recognized as one of the twelve most recent hallmarks of aging. Recent studies have linked these changes to a variety of age-related neurological disorders, including Alzheimer's disease, amyotrophic lateral sclerosis, Parkinson's disease, multiple sclerosis, and Huntington's disease. Specifically, the gut microbiota influences the brain through the production of key metabolites such as short-chain fatty acids and the activation of inflammatory and other relevant signaling pathways. In preclinical studies, targeted modulation of the gut microbiota, through methods such as fecal microbiota transplantation, probiotics, and prebiotics, has demonstrated potential in improving host behavioral outcomes. Therefore, gut microbiotabased treatments offer new hope for the treatment of nervous system diseases. However, due to the complexity of the gut microbiota and the potential adverse reactions associated with these therapies, researchers need to carefully assess their safety and efficacy before widespread clinical application.},

abstract = {INTRODUCTION: Juvenile amyotrophic lateral sclerosis (J-ALS) is extremely rare neurodegenerative motor neuron disorder that begins in early childhood or adolescence, before the age of 25 years old. It is characterized by gradual disease progression with comparison to adult-onset ALS and is often linked to genetic mutations.

CASE PRESENTATION: A 16-years-old female presented with long history of generalized weakness since age of 10 years, followed by bilateral sensorineural hearing loss, bulbar symptoms, and limb spasticity. Neurological examination revealed upper motor neuron signs in upper limbs, lower motor neuron signs in lower limbs, and bulbar involvement. Nerve conduction test was normal however, MRI showed early degenerative changes, and diagnosed with J-ALS after careful evaluation. She was started on Riluzole. Despite ICU care and supportive interventions including PEG and tracheostomy, she succumbed to respiratory failure.

DISCUSSION: Rarity, atypical presentation, and finical constraints can delay diagnosis of J-ALS. However, early diagnosis after careful evaluation of clinical symptoms, medical history, electrophysiological and imaging studies followed by prompt treatment with Riluzole and supportive interventions can help prolong survival and improve quality of life.

CONCLUSION: J-ALS is a rare motor neuron disease which possess immense diagnostic challenges, can exhibit relentless progression over short period of time with time.},

abstract = {OBJECTIVES: We investigated the relationship between cystatin C- and creatinine-based estimated glomerular filtration rate (eGFRdiff) and amyotrophic lateral sclerosis (ALS) outcomes.

METHODS: We enrolled ALS patients diagnosed between January 2014 and December 2019. Experienced neurologists followed up the participants until January 2022. Absolute difference between eGFR (eGFRabdiff) and relative difference between eGFR (eGFRrediff) were obtained. Cox proportional hazard models were used to evaluate the relationship between eGFRdiff and ALS survival.

RESULTS: Negative eGFRabdiff were common in the patients (74.7%). For each SD increase of eGFRabdiff, the risk of poor prognosis for ALS patients decreased by 1.9% (HR, 0.981; 95% CI, 0.973-0.989). For each 10% increment in eGFRrediff, the risk of poor prognosis for ALS patients decreased by 17.7% (HR, 0.823; 95% CI, 754-0.898).

CONCLUSIONS: We found that large eGFRdiff was associated with poor prognosis in ALS. Monitoring eGFRdiff in ALS population facilitates prognostic stratification assessment and precise management.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder affecting both upper and lower motor neurons. ALS is classically characterized by painless progressive weakness, causing impaired function of limbs, speech, swallowing, and respiratory function. The disease is fatal within 2-4 years, often the result of respiratory failure. The pathologic hallmark for a majority of ALS cases is aberrant cytoplasmic accumulations of the nuclear protein TAR-DNA binding protein (TDP-43). A total of 10-15% of ALS can be attributed to a single gene mutation, known as genetic or "familial" ALS, while the remainder of cases are termed nongenetic or "sporadic" although heritability has been measured in up to 37% in this population. Complex interactions between genetics, environment, and physiologic susceptibility are thought to contribute to disease. Management is primarily supportive in nature, though there are several approved treatments worldwide. This review details the mechanisms and evidence of approved disease-modifying treatments, relevant measures to track disease burden and progression used in clinical trials, and approaches to pharmacologic management of common symptoms in ALS. As there is not currently a cure for ALS, research into the complex pathophysiologic and genetic alterations contributing to disease is of great interest. This review further discusses the current understanding of genetic etiologies and altered physiology leading to disease, such as neuroinflammation, integrated stress response, aberrant proteostasis and mitochondrial dysfunction, among others. The translation of preclinical discoveries into current investigational therapeutics, novel therapeutic categories such as antisense oligonucleotides and stem cell transplantation, as well as future horizons harnessing the power of artificial intelligence in drug development and clinical trials are discussed.},

abstract = {Current methods of processing accumulated polyolefin waste typically require harsh conditions, precious metals or high metal loadings to achieve appreciable activities. Here we examined supported, single-site organonickel catalysts for polyolefin upcycling. Chemisorption of Ni(COD)2 (COD, 1,5-cyclooctadiene) onto Brønsted acidic sulfated alumina (AlS) yields a highly electrophilic Ni(I) precatalyst, AlS/Ni(COD)2, which is converted under H2 to the active AlS/Ni[II]H catalyst. This single-site system exhibits unique hydrogenolysis selectivity that favours cleaving branched polyolefin C-C linkages, enabling the hydrogenolytic separation of polyethylene and isotactic polypropylene (iPP) mixtures. Moreover, AlS/Ni[II]H remains highly selective and active for hydrogenolysis of iPP admixed with polyvinyl chloride, and the spent catalyst can be repeatedly regenerated by AlEt3 treatment. Experimental mechanistic analysis and density functional theory modelling reveal a turnover-limiting C-C scission pathway featuring β-alkyl transfer and strong olefin binding. These results highlight the potential of nickel-based systems for the selective upcycling of complex plastic waste streams.},

Current therapeutic strategies often fall short in halting or reversing disease progression, highlighting the urgent need for novel approaches. Extracellular vesicles (EVs) have garnered attention as potential therapeutic agents due to their role in intercellular communication and their ability to transport bioactive cargo, including proteins, nucleic acids, and lipids. This review provides a comprehensive overview of the biology of EVs, their involvement in neurodegenerative diseases, and the potential for EV-based therapies. We discuss the different types of EVs, their biogenesis, and their cargo composition, emphasizing their relevance to neurological processes such as protein misfolding, neuroinflammation, and oxidative stress. Preclinical studies investigating EVs as carriers of therapeutic cargo and their ability to promote neuronal survival and regeneration are examined, with a focus on evidence from animal models of neurodegenerative disorders. We explore the use of EVs in the treatment of neurodegenerative diseases, including ongoing clinical trials, methods for EV isolation and modification, and future perspectives on personalized EV-based therapies designed to meet the unique needs of individual patients. Overall, this review highlights the potential of EVs as a promising avenue for neurodegenerative disease therapy, while also addressing key research gaps and translational hurdles that need to be overcome for their successful clinical implementation.},

abstract = {BACKGROUND: Spinal dural arteriovenous fistulas (SDAVFs) are the most prevalent type of spinal vascular malformation and can lead to progressive neurological impairments if left untreated. Endovascular embolization and microsurgical resection are treatment options, although the optimal treatment method remains a subject of debate.

OBJECTIVE: A comprehensive systematic review and meta-analysis to compare the endovascular and microsurgical treatment outcomes of SDAVFs.

METHODS: An exhaustive literature search was conducted in the PubMed, Embase, Scopus, and Web of Science databases, encompassing publications from 2014 to 2024. A total of 522 patients from seven studies (417 surgical and 105 endovascular) met the inclusion criteria. Information on post-treatment complications, recurrence/failure rates, and functional improvement as assessed by the Aminoff-Logue Scale (ALS) or modified ALS (mALS) was extracted. I[2] statistics were used to evaluate heterogeneity, and random-effects models were used to compute risk ratios (RRs) and odds ratios (ORs).

RESULTS: Compared to endovascular intervention, surgical treatment was linked to significantly lower rates of recurrence or treatment failure (RR: 0.19; 95% CI: 0.09-0.39; p < 0.001), especially in long-term follow-up and thoracic-level studies. With greater ALS/mALS gains and a higher percentage of patients achieving full or partial recovery, functional improvement favored surgery. Although complication types varied, complication rates were similar across modalities (OR: 0.84; 95% CI: 0.48-1.49). Asymmetry in funnel plots indicated possible publication bias in favor of successful surgical outcomes.

CONCLUSION: For SDAVFs, surgical ligation provides better long-term results than endovascular embolization in terms of neurological recovery and recurrence prevention. Even though both procedures are usually safe, surgery is the recommended first-line course of action due to the higher failure and recurrence rates linked to embolization, especially in patients with operable anatomy and progressive symptoms.},

abstract = {INTRODUCTION: There are a few therapeutic approaches for Amyotrophic Lateral Sclerosis (ALS) which can only slow down or stop the disease progression for a limited period of time. Since it has been proven that Mesenchymal Stromal Cells (MSCs) produce neurotrophic factors and have some neuroprotective effects, stem cell therapy has been proposed as an alternative or add-on treatment for ALS patients.

METHOD & MATERIAL: In this open-label clinical trial, two-repeated dose of 60 million GMP compliant Wharton's Jelly-derived Mesenchymal Stromal Cells (WJ-MSCs) were transplanted intrathecally (#6 patients) or intravenously (#6 patients) twice with a 3-month interval.

RESULTS: No adverse events related to the intervention or injected cells were reported. While no significant improvement in the total revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R) score or overall clinical efficacy was achieved, patients reported improvements in specific sub-items such as salivation, swallowing, and their speech. Additionally, reductions in muscle tremors and fasciculations, as well as increased muscle strength were observed.

CONCLUSION: In conclusion, using WJ-MSCs is safe and feasible in ALS patients, but the efficacy of these cells should be assessed in future studies with more patients, different routes of cell administration, and maybe with higher doses of the injected cells.},

PATIENTS & METHODS: Amerita Specialty Infusion Services provided IV edaravone to patients with ALS treated with their first dose between 25 September 2017-30 September 2022. Mean ALS Functional Rating Scale-Revised (ALSFRS-R) scores and forced vital capacity (FVC) %-predicted measures were recorded within ± 100 days from care initiation to approximate baseline values.

RESULTS: Included patients (n = 243) received/were still receiving IV edaravone/edaravone oral suspension as of 30 September 2022. At initiation, 66.7% were male, mean age ± SD was 61.2 ± 11.2 years, and 61.3% were covered by government insurance. In patients with provider-recorded ALSFRS-R (n = 115) and FVC (n = 84) %-predicted measures within ± 100 days from care initiation, mean ± SD values were 35.1 ± 8.9 and 72.3% ± 21.7%, respectively. Mean ± SD therapy duration was 13.5 ± 11.4 months. Discontinuation reasons included death/hospice (n = 82), patient's choice (n = 38), doctor's choice (n = 31), insurance (n = 18), and other (n = 12). Reasons for IV edaravone discontinuation and IV edaravone administration access device were not associated.

CONCLUSIONS: Treatment discontinuation was primarily related to ALS disease progression/death, rather than safety or tolerability. This study representative of real-world patients with ALS suggests that edaravone showed consistent safety and tolerability profiles with previous studies.},

Beyond its well-established antioxidant properties, edaravone demonstrates significant anti-inflammatory and immunomodulatory activities, including the inhibition of key pathways such as NF-κB, JAK2/STAT3, and TLR4/IL-6, suggesting potential to modulate immune responses within the tumor microenvironment. This review discusses how edaravone disrupts oncogenic signaling, induces cell cycle arrest, and enhances apoptosis, particularly in cancer stem cells and therapy-resistant models. It also examines edaravone's dual role in combination therapies, where it may improve the cytotoxicity of chemotherapeutic and radiotherapeutic agents while simultaneously protecting normal tissues from treatment-induced toxicities. By linking mechanistic insights with therapeutic outcomes, this review highlights the rationale for repurposing edaravone as a potential adjuvant in cancer therapy.

METHODS: To apply finite mixture modeling to pre-post Hamilton Depression Rating Scale (HDRS) differences (n = 2184) of STAR*D study's level 1, a single-arm, open-label study. For a successful replication, the best fitting model had to be trimodal, with comparable components as in Stone et al. Secondary/sensitivity analyses repeated the analysis for different baseline levels of depression severity, imputed values, and patient-reported depression symptoms.

RESULTS: The best fitting models were either bimodal or trimodal but the trimodal solution did not meet criteria for replication. The bimodal model had one component with HDRS mean change of M = -13.0, SD = 6.7 and included 65.3% of patients, and another component with M = -1.8, SD = 5.1, 34.7%, respectively. For the trimodal model, the component with the largest change (M = -14.3, SD = 6.4) applied to 52% of patients, which differed substantially from the large effect component in Stone et al. (M = -18.8, SD = 5.1) which applied to 7.2%. Secondary/sensitivity analyses arrived at similar conclusions and for patient-reported depression symptoms the best fitting models were unimodal or bimodal.

CONCLUSIONS: This analysis failed to identify the trimodal distribution of response reported in Stone et al. In addition to being difficult to operationalize for regulatory purposes, results from mixture modeling are not sufficiently reliable to replace the more robust approach of comparing mean differences in depression rating scale scores between treatment arms.},

abstract = {Rationale: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by the progressive loss of motor neurons in the central nervous system (CNS). Non-neuronal cells, particularly astrocytes, have been recognized as pivotal contributors to ALS onset and progression. However, the underlying mechanisms of interactions between astrocytes and motor neurons during ALS remain unclear. Recent studies have identified the neuronal Hippo kinase mammalian sterile 20-like kinase 1 (MST1) as a key regulator of neurodegeneration in ALS. Yes-associated protein (YAP), a major downstream effector of the Hippo pathway, is predominantly expressed in astrocytes. However, the role of astrocytic YAP in ALS and its underlying mechanisms remain unexplored. Methods: To evaluate the function of YAP in ALS, we established a C9orf72-poly-GA mouse model (ALS mice) via intracerebroventricular injection of AAV viruses. Furthermore, mice with conditional knockout (CKO) of YAP in astrocytes (YAP[GFAP]-CKO mice) were generated and then YAP[GFAP]-CKO ALS mice and their littermate controls (YAP[f/f] ALS mice) were used as experimental subjects. Behavioral tests, immunostaining, Nissl staining, quantitative real-time PCR (qPCR), and Western blotting were used to assess the effects of astrocytic YAP deletion in ALS progression. In addition, we investigated the role and mechanism of astrocytic YAP in the pathogenesis of ALS by integrating RNA sequencing (RNA-seq) from primary cultured astrocytes with single-nucleus transcriptomic (snRNA-seq) from C9orf72-ALS/FTD patients. Then, in vitro experiments including primary cultured astrocytes and neurons were used to further elucidate the potential molecular mechanism of astrocytic YAP in ALS. Finally, we evaluated the therapeutic effects of the excitatory amino acid transporter-2 (EAAT2) activator LDN-212320 and the Hippo kinase MST1/2 inhibitor XMU-MP-1 as candidate treatments for ALS. Results: We found that YAP was upregulated and activated specifically in astrocytes, but not in neurons or microglia, within the motor cortex of ALS mice. Conditional knockout of YAP in astrocytes exacerbated motor deficits, neuronal loss, pathological translocation of TDP-43, inflammatory infiltration, and reduced astrocytic proliferation in ALS mice. Mechanistically, Wnts secreted by degenerating neurons and astrocytes activated YAP/β-catenin signaling and further promoted the expression of EAAT2 in astrocytes, which prevented neuronal glutamate excitotoxicity, neuronal loss, and motor dysfunction in ALS mice. Interestingly, treatment with LDN-212320 promoted EAAT2 expression and partially restored motor deficits and neuronal loss in YAP[GFAP]-CKO ALS mice. Finally, activation of YAP by XMU-MP-1 upregulated β-catenin and EAAT2 expression, and partially alleviated motor deficits and neurodegeneration in ALS mice. Conclusions: These results identify an unrecognized mechanism of self-protection in degenerating neurons mediated by astrocytic YAP through Wnts/β-catenin/EAAT2 signaling to prevent glutamate excitotoxicity of neurons in ALS mice, and provide a novel drug target for ALS.},

abstract = {Astrocytes, the most prevalent glial cells in the central nervous system (CNS), play crucial roles in maintaining CNS homeostasis and responding to various pathological stimuli. They play key roles in neural development, neurotransmission, neuroinflammation, metabolic support, and tissue repair. Recent advancements in single-cell sequencing have revealed the remarkable heterogeneity of astrocytes, with distinct subpopulations differentially contributing to disease progression in neurological disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, ischemic stroke, intracerebral hemorrhage, and multiple sclerosis. In addition, they play an important role in various behavioral neuropsychiatric disorders. This review highlights the dual roles of astrocytes in disease progression, driven by their diverse molecular profiles and functions. It outlines the key molecular mechanisms underlying astrocyte heterogeneity and their impact on neuroinflammation, neuronal support, and ionic balance regulation. Additionally, the review discusses potential therapeutic strategies targeting astrocytes to modulate these processes, aiming to improve treatment outcomes in neurological diseases. By elucidating the specific roles of astrocyte subsets in disease, this review seeks to advance the development of precision medicine for astrocyte-related neurological disorders.},

EAP data can be collected in parallel to randomized clinical trials (RCTs) and serve as a source of evidence in clinical practice. Here, we present the results of a National Institutes of Health (NIH)-funded EAP for amyotrophic lateral sclerosis (ALS).

METHODS: Participants received trehalose, a drug studied in a parallel RCT, for up to 24 weeks; clinical and biomarker data were collected throughout the study.

RESULTS: Seventy participants were enrolled at 20 study centers across the United States. Treatment with trehalose did not affect the levels of neurofilament light chain [estimated flat slope per month was -0.005, SE = 0.0078; 95% CI (-0.021, 0.011)] or disease progression [estimated least square mean change of the ALS Functional Rating Scale-Revised total score and slow vital capacity (percent predicted) from baseline to Week 24 were -5.6 (0.67); 95% CI (-7.0, -4.3) and -4.53 (4.308); 95% CI (-13.55, 4.48)], respectively. No unexpected treatment-related risks were identified. Serious adverse events were deemed not related to trehalose (20 occurrences in 13 [18.6%] participants with eight deaths).

DISCUSSION: This EAP establishes a framework for implementing multi-center EAPs that complement data collected from RCTs. Additional NIH-funded EAPs are currently underway. Data and additional serum samples collected in this study are available to the research community for further study.

Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments. Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments.},

Calmodulin (CaM) is a calcium sensor and the primary regulator of receptors and ion channels that maintain calcium homeostasis. The calmodulin binding domains are present in proteins that serve as risk factors and biomarkers associated with Alzheimer's disease, Parkinson's disease, Huntington's disease, Amyotrophic Lateral Sclerosis, and other neurodegenerative diseases, suggesting calmodulin ligands as emerging therapeutic targets for treatment. Inhibiting CaM to develop new therapies has drawbacks, as CaM is a ubiquitous molecule involved in many regulatory pathways. Recently, new strategies for disrupting CaM interactions with its targets have shown promising approaches to treatment. The structures of human CaM, its binding proteins, and inhibitors are well studied, with particular emphasis on the conservation of CaM amino acid sequences and the ability to bind protein fragments of high sequence variability, which exhibit common characteristics of amphipathic helices carrying basic amino acids. In this review, we discuss structural characteristics of CaM and its ligands in the context of transcriptional regulation. Specific binding of CaM to (1) basic region/helix-loop-helix/leucine zipper and (2) helix-turn-helix high mobility group box containing Sox families of transcription factors highlights common features of CaM binding sequences, which suggest their regulatory functions. We describe key proteins involved in neurodegeneration and transcription factors subject to calmodulin regulation that are candidates for the development of new approaches to treating neuronal diseases.},

Additional research has suggested that diabetic subjects treated with glucagon-like peptide-1 (GLP-1) receptor agonists exhibit a reduced incidence of PD compared to those receiving other anti-diabetic medications. GLP-1 receptor agonists are FDA-approved therapies for T2DM, and recent studies have explored their potential as repurposed treatments for neurodegenerative diseases, including PD, AD, and ALS, as well as cerebrovascular disorders. This systematic review aims to assess the available literature on the efficacy and safety profiles of GLP-1 receptor agonists in PD management. A comprehensive search of PubMed, Scopus, CENTRAL, Web of Science, Embase, and ClinicalTrials.gov was conducted to identify relevant studies. The primary outcomes of this review include motor impairment in PD, as assessed by MDS-UPDRS Part III, as well as motor complications (Part IV) and motor experiences of daily living (Part II), and the incidence of gastrointestinal and systemic side effects. Meta-analysis showed that GLP-1 receptor agonists significantly improved motor function, as reflected by MDS-UPDRS Part III scores in the ON state (mean difference = - 2.88; p = 0.01; I[2] = 30%), although they were associated with a higher incidence of adverse events across all safety outcomes. Findings and conclusions of this review will contribute to a clearer understanding of the therapeutic potential of GLP-1 receptor agonists in PD, guiding future clinical research and treatment strategies.},

abstract = {BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disorder that progressively affects motor neurons. Gain-of-function mutations in serine palmitoyltransferase (SPT) genes, notably SPTLC1 and SPTLC2, have been linked to juvenile ALS. Here, we describe two childhood-onset ALS cases with distinct SPTLC2 mutations, providing new insights into sphingolipid dysregulation and its role in ALS pathogenesis.

MATERIAL AND METHODS: Two Chinese patients with early-onset ALS, both carrying SPTLC2 mutations, were recruited from Beijing Children's Hospital. We conducted whole-exome sequencing (WES) to identify genetic variants, followed by Sanger sequencing for validation. Sphingolipid profiles were analyzed using ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Clinical evaluations included neurological assessments, brain MRI and electromyography. Additionally, mutant cell lines were established to assess the functional effects of the specific mutations.

RESULTS: Patient 1, a 6-year-old male, exhibited a novel heterozygous de-novo SPTLC2 variant (c.197T > G, p.T66R). Patient 2, a 7-year-old female, had a recurrent heterozygous de-novo SPTLC2 variant (c.778G > A, p.E260K). Both patients showed elevated levels of specific sphingolipids compared to controls, with distinct profiles between the SPTLC2-ALS and SPTLC1-hereditary sensory and autonomic neuropathy type 1 (HSAN1) cases. The novel p.T66R mutation was predicted to alter protein interactions within the SPT complex, potentially impairing sphingolipid homeostasis. Functional studies further revealed that the p.T66R variant reduces the inhibitory regulation of SPT by ORMDL proteins, leading to unrestrained SPT activity and excess sphingolipid production.

CONCLUSIONS: Our findings identify a novel SPTLC2 variant linked to childhood-onset ALS and reveal altered sphingolipid profiles associated with different genetic mutations. These results underscore the importance of sphingolipid metabolism in ALS and suggest potential avenues for targeted therapeutic interventions. Further research is needed to explore treatment options aimed at modulating sphingolipid levels and correcting genetic defects, as well as investigating potential biomarkers for early diagnosis.},

Structurally composed of a G3BP1-interacting motif, a N-terminal domain (mediating most protein interactions), and a catalytic USP domain (residues 415-795, catalytic triad C424-H736-D751), USP10 regulates diverse cellular pathways by stabilizing key proteins through deubiquitination. It exhibits context-dependent functional duality, particularly in cancer: USP10 promotes tumorigenesis in various cancers (e.g., glioblastoma, esophageal, pancreatic, breast cancers) by stabilizing oncoproteins like CCND1, YAP1, HDAC7, and RUNX1, enhancing proliferation, metastasis, and immune evasion. Conversely, it suppresses tumors (e.g., NSCLC, CRC, thyroid cancer) by stabilizing tumor suppressors like p53, PTEN, and Axin1, inhibiting pathways such as Wnt/β-catenin. Beyond oncology, USP10 contributes to neurodegenerative diseases (neuroprotective in PD/ALS, neurotoxic in AD via Tau stabilization), viral immunity (inhibits SARS-CoV-2 infection), inflammatory responses, male reproduction, and metabolic/cardiovascular disorders. Its regulatory mechanisms include phosphorylation (e.g., by AMPK, AKT, ATM) controlling subcellular localization and activity, and ubiquitination via USP13. USP10's therapeutic significance drives inhibitor development (Spautin-1, D1, Wu-5, P22077, Parthenolide), though cross-reactivity within the USP family due to conserved catalytic domains remains a challenge. Novel strategies like PROTACs and engineered ubiquitin variants (UbVs) offer promise for future selective targeting of USP10 dysregulation in diverse diseases. A comprehensive understanding of its structure and context-specific functions is essential for exploiting its full therapeutic potential.},

abstract = {BACKGROUND: Spinal dural arteriovenous fistula (sDAVF) is a rare cause of myelopathy and progressive paraplegia. sDAVFs are the most frequent type of spinal vascular malformation and comprise 70 % of all vascular spinal malformations. Despite the availability and published efficacy of both microsurgical resection and endovascular embolization, the optimal treatment for sDAVFs remains to be determined. We aimed to assess the efficacy of a multimodal treatment approach to sDAVFs at our institution.

METHODS: A retrospective review of all sDAVFs treated between 1998 and 2021 at Stanford Hospital and Clinics was conducted. The medical records were inspected and data, including presenting symptoms, duration, angiographic features, and treatment modality, were extracted. Cure was defined as the absence of an arteriovenous fistulous connection on digital subtraction angiography and radiologic improvement on follow-up MRI. Functional outcomes were assessed at presentation and at last follow-up using the Aminoff-Logue Scale (ALS).

RESULTS: 47 patients underwent treatment of sDAVFs between August 1998 to May 2021. As an initial treatment, 32 patients underwent microsurgical excision, and 15 had endovascular embolization. Radiological cure was achieved in 84.4 % of patients during the first treatment and in 97.9 % of patients at the final treatment time point. At initial treatment, surgery cured the sDAVF in 84.4 % of patients, with endovascular embolization curing in 86.7 % of patients. When assessed as an additional treatment for failed prior treatment, surgery achieved cure in 80 % of patients and endovascular embolization in 100 % of patients. At all time points, high cure rates were observed, with success rates achieving 96.9 % and 100 % for surgery and endovascular embolization, respectively. A significant improvement in ALS Gait score was noted after treatment, with a mean reduction of 0.6 from baseline (p = 0.0003). A similar improvement trend was observed in the ALS Micturition score with a mean decrease of 0.3 points (p = 0.057).

CONCLUSIONS: Our study demonstrates high efficacy for cure and improved functional outcomes in both surgical and endovascular treatments, assuming good patient selection. This series also highlights the importance of a multimodality treatment approach in managing spinal dural arteriovenous fistulae. Further delineation is required to determine the radiological and patient factors that might recommend specific initial treatment modalities.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is a complex neurodegenerative disorder characterized by the death of motor neurons in the spinal cord and brain regions, leading to a reduced survival rate in patients. Nearly 20 gene mutations are associated with ALS, with SOD1, FUS, TARDBP, and C9orf72 mutations being more common. Ninety percent of ALS cases are related to sporadic ALS, while the remaining 10 % are associated with familial ALS. CRISPR/Cas9, a genome engineering technology known as clustered regularly interspaced short palindromic repeats/CRISPR-associated system 9, has the potential for gene editing and for studying the underlying mechanisms of ALS in mouse models. This technique enables neuroscientists to reverse mutations found in ALS mouse models, providing new hope for understanding the complexities of ALS. Additionally, this tool can create mutations to probe the functional changes of genetic diseases. Using CRISPR/Cas9 with an in vivo delivery method involving adeno-associated vectors, it is possible to silence mutations in the SOD1-linked ALS mouse model. Some limitations related to CRISPR/Cas9 have been discussed in previous studies and need to be addressed before clinical trials can proceed. In this review-based study, we summarise the latest research on CRISPR/Cas9 genome editing for ALS in mouse models and discuss its limitations and future prospects as well.},

abstract = {BACKGROUND: Human papillomavirus (HPV) vaccine coverage (VC) remains lower than expected in France. The PrevHPV national research program aimed to codevelop and evaluate an intervention including three components: 'education and motivation' of adolescents in schools, 'at-school vaccination', 'general practitioners (GPs)' training'. This study aimed to evaluate the implementation outcomes of each component, whether they affected effectiveness, and identify factors influencing implementation in schools.

METHODS: A mixed-method study embedded in a cluster randomized controlled trial in 91 French municipalities (July 2021-June 2022). Quantitative data were collected through activity reports and questionnaires, and qualitative data through focus groups with school staff. The implementation outcomes were fidelity, dose, reach, acceptability and sustainability, as defined in the Medical Research Council guidance for process evaluation of complex interventions and Proctor et al.'s Implementation Outcomes Framework; the effectiveness outcome was HPV VC (≥ 1 dose) two months after the end of the intervention. Qualitative data were analyzed using the Consolidated Framework for Implementation Research.

RESULTS: The fidelity, acceptability, and sustainability of all three components among participants who completed the intervention were high. However, the withdrawal of one-third of schools before the trial started and difficulties in mobilizing GPs negatively impacted the dose and reach outcomes. Estimates for the on-treatment analyses of the effectiveness were greater than those for which the dose of intervention received was not considered; 'at-school vaccination' (11.25 percentage points, p < 0.001) and 'GPs' training' (3.56 percentage points, p = 0.049) increased VC, while 'education and motivation' remained nonsignificant.

CONCLUSIONS: Increasing HPV VC among adolescents could be achieved by combining interventions in both schools and primary care settings. This study provides practical implications for implementing such interventions in real life.

abstract = {PURPOSE OF REVIEW: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with few treatment options available. The approval of tofersen, an antisense oligonucleotide, for SOD1-ALS by the FDA and EMA may herald a new era of treatment in these patients.

RECENT FINDINGS: So far, trials against the most common genetic form of ALS, C9orf72, have been unsuccessful, but new preclinical data may show a promising new direction to take. Clinical trials targeting other, more rare genetic mutations associated with familial ALS are currently underway. Other research assessing the use of ASOs to target aberrant splicing associated with sporadic forms of ALS has also produced promising results in preclinical models, using patient-derived induced cellular models and animal models. These therapies are focussed largely on alleviating and reversing TDP-43 pathology, opening up the possibility of not only arresting disease progression, but reversing neurodegeneration.

SUMMARY: ASO therapies have made some promising steps towards treating familial ALS, particularly SOD1. Ongoing early clinical/preclinical phase research is underway to utilise this technology in other genetic mutations linked with ALS, as well as in sporadic cases.},

RECENT FINDINGS: Neurofilaments, especially NFL, have been confirmed to be good biomarkers for ALS. NFL may be diagnostically useful but its main role is as prognostic and pharmacodynamic biomarker. Inflammatory biomarkers, especially the chitinases, might also serve as pharmacodynamic biomarkers in treatment trials targeting neuroinflammation. GFAP could reflect cognitive-behavioural impairment. CSF dipeptides are diagnostic biomarkers for ALS caused by the C9ORF72 exanucleotide repeat expansion and may be used to confirm target engagement by experimental drugs. Levels of TDP-43 (virtually the ideal biomarker for ALS) in CSF and plasma have not been demonstrated to be consistently altered in ALS. However, promising advancements have been achieved in seed amplification assays for the protein, in its quantification in plasma extracellular vesicles, and in the measurement of CSF levels of a protein reflecting splicing dysfunction of TDP-43. Finally, blood phosphorylated tau has emerged as an ALS biomarker linked to lower motor neuron (or muscle) pathology.

SUMMARY: NFL is still the best neurochemical biomarker for ALS. However, substantial advances have been recently made, especially regarding detection of TDP-43 and blood phosphorylated tau.},

After reviewing 76 full-text articles, 12 studies satisfied the inclusion criteria for data extraction and thematic analysis, consisting of five qualitative and seven quantitative studies. A time frame of 10 years was considered, ranging from 2014 to 2024. This scoping review revealed that pseudo-stoic attitudes in cancer patients often lead to emotional suppression, reduced social support, delayed help-seeking and poor management of symptoms such as pain. These attitudes were linked to poorer psychological outcomes and underreporting of symptoms, especially among older males and rural cancer patients. Studies found that stoic traits were sometimes associated with persistence and treatment adherence among cancer patients. Pseudo-stoicism hinders emotional expression and delays help-seeking, leading to adverse health outcomes; however, stoic attitudes are also associated with adaptive qualities, such as psychological endurance and a commitment to care. Therefore, it is vital to promote balanced coping strategies that honour resilience while encouraging open emotional engagement among cancer patients.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by motor neuron (MN) degeneration. Ropinirole hydrochloride (ROPI), a dopamine receptor D2 (DRD2) agonist, was identified through phenotypic screening of MNs derived from patient-derived induced pluripotent stem cells (iPSCs) as a disease model and has emerged as a promising candidate drug for ALS treatment. The ROPALS trial, a phase I/IIa trial in patients with ALS, suggested the safety and efficacy of ROPI, albeit in a small sample size. Interestingly, a DRD2 antagonist and modulator only partially mitigated the suppressive effect of ROPI on the ALS phenotype, and the detailed mechanism of ROPI activity remains unclear. Therefore, in this study, we investigated whether the therapeutic effects of ROPI in ALS are dependent on DRD2. For this purpose, we generated DRD2-deficient iPSCs and showed that ROPI effectively reduced neuronal cell death, reactive oxygen species (ROS) production, and neuronal hyperexcitation, independently of DRD2. Further analyses revealed that ROPI corrected aberrant RNA splicing and restored the mRNA expression of mitochondrial proteins in a DRD2-independent manner. Our findings suggest that ROPI not only functions as a canonical DRD2 agonist but also has pleiotropic DRD2-independent effects, offering a novel avenue for treatment strategies that target multiple pathways involved in ALS pathology.},
