abstract = {More than 65 million people worldwide experience neurodegenerative diseases, such as Alzheimer disease, frontotemporal dementia, Parkinson disease, and amyotrophic lateral sclerosis. As the risk of developing these diseases increases with age, increasing life expectancy will further accelerate their prevalence. Despite major advances in the understanding of the molecular mechanisms of neurodegeneration, no curative therapy is available to date. Neurodegenerative diseases are known to be associated with alterations in serotonergic neurotransmission, which might critically contribute to the pathogenesis of these diseases. Therefore, targeting the serotonergic system appears to be a promising therapeutic approach. In this review, we provide a comprehensive overview of pathological changes in serotonergic neurotransmission in different neurodegenerative diseases and discuss novel treatment strategies based on targeted modulation of the serotonergic system. We primarily focus on the therapeutic approaches modulating serotonin homeostasis, its biosynthesis, and the modulation of defined serotonin receptors. SIGNIFICANCE STATEMENT: A common feature of multiple neurodegenerative diseases is dysregulation of the serotonergic system at the cellular, molecular, and genetic levels that strongly contributes to specific pathological phenotypes. Targeting these alterations represents a suitable therapeutic strategy to combat disease-relevant pathomechanisms, slow down disease progression, and overcome pathological consequences.},

The ALS was characterized for their chemical structure and surface activity. Furthermore, ALS was used as a thermal cleaning agent to treat oily sludge under different conditions to obtain an optimal thermal washing process. Finally, the oily sludge before and after thermal washing were characterized to explore its structural and compositional changes. Results obtained from the Fourier Transform Infrared spectroscopy (FT-IR) and Two-dimensional Heteronuclear Single Quantum Coherence(2D-HSQC) confirmed the successful grafting of fatty acid chains(C12) onto the LS molecules. ALS was an ideal surfactant with suitable HLB value and excellent surface tension reduction, foaming and emulsification properties. The optimum thermal washing process for oily sludge was: thermal washing temperature 30 °C, ALS concentration 1.5 g/L.},

abstract = {In neurons, mitochondria generate energy through ATP production, thereby sustaining the high energy demands of the central nervous system (CNS). Mitochondrial dysfunction within the CNS was implicated in the pathogenesis and progression of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis, often involving altered mitochondrial dynamics like fragmentation and functional impairment. Accordingly, mitochondrial targeting represents an alternative therapeutic strategy for the treatment of these disorders. Current standard drug treatments present limitations due to adverse effects associated with their chronic use. Therefore, in recent years, nutraceuticals, natural compounds exhibiting diverse biological activities, have garnered significant attention for their potential to treat these diseases. It has been shown that these compounds represent safe and easily available sources for the development of innovative therapeutics, and by modulating mitochondrial function, nutraceuticals offer a promising approach to address neurodegenerative pathologies. We referred to approximately 200 articles published between 2020 and 2025, identified through a focused search across PubMed, Google Scholar, and Scopus using keywords such as "nutraceutical," "mitochondrial dysfunction," and "neurodegenerative diseases. The purpose of this review is to examine how mitochondrial dysfunction contributes to the genesis and progression of neurodegenerative diseases. Also, we discuss recent advances in mitochondrial targeting using nutraceuticals, focusing on their mechanisms of action related to mitochondrial biogenesis, fusion, fission, bioenergetics, oxidative stress, calcium homeostasis, membrane potential, and mitochondrial DNA stability.},

abstract = {INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons in the spinal cord and brain. We have developed a novel non-invasive approach, MultiPath-DCS, which utilizes direct current stimulation at multiple sites along the neural axis to provide simultaneous spinal and peripheral stimulation targeted at the affected limbs. MultiPath-DCS modulates the excitability of spinal cord neurons. This effect is significant for ALS, as motor neuron hyperexcitability is a fundamental characteristic of the disease.

METHODS: This study used a transgenic mouse model of ALS (SOD1-G93A). Anodal-MultiPath-DCS was applied with six electrodes: three on the spine (centered on T13 and with an anodal polarity), two on the sciatic nerves (one on each nerve), and one on the abdomen. Mice were divided into two groups (stimulated vs. unstimulated or sham-stimulated). The stimulated animals received stimulation for one hour a day, three times a week, for three weeks. Survival was calculated from the onset of the disease and birth until the animal's endpoint. We also performed various electrophysiological and molecular experiments to uncover the mechanism of action.

RESULTS: We demonstrated molecular changes induced by anodal MultiPath-DCS, including (a) reduced expression of mutant SOD1 protein, (b) decreased expression of elevated NKCC1, (c) reduced phosphorylated tau, (d) increased expression of HSP70, and (e) increased expression of LC3B. Additionally, we found that treatment with Anodal-MultiPath-DCS (anode on the spinal column) reduces long-term neuronal spinal excitability, slows the progression of muscle weakness, and extends the lifespan of stimulated mice. The mean survival time in the control group was 12.4 days. In comparison, the mean survival time in the stimulated group was 21.6 days using a therapeutic stimulation paradigm, representing a 74% increase in survival from disease onset. Spinal motor neuron survival showed a 54% increase in stimulated compared to non-stimulated groups.

DISCUSSION: Combined, this data provides evidence that Anodal-MultiPath-DCS reduces hyperexcitability and enhances the clearance of misfolded proteins by modulating autophagy and proteolytic systems. By decreasing spinal excitability and clearing toxic proteins from motor neurons, Anodal-MultiPath-DCS promotes survival and could serve as a disease-modifying intervention for ALS.},

abstract = {In various neurodegenerative disorders, inflammation and associated inflammasome activation play an important role. The most prevalent and extensively researched inflammasomes are NLRP3 inflammasomes, which are triggered by pathogens or danger signals mediating inflammatory reaction. Extracellular ATP also activates NLRP3 by stimulating the purinergic receptor P2X7 (P2X7R). Central and peripheral cells, including those in the gut, have been shown to have activated inflammasomes during pathological changes co-occurring with inflammation in various neurodegenerative disorders. Gut injury or dysfunction is increasingly recognised as one of the peripheral pathogenic characteristics of many neurodegenerative disorders, and has been found to associate with changes in gut microbes. In this article, we review data from preclinical and clinical studies regarding the involvement of the NLRP3 inflammasome and the purinergic receptor P2X7R in the pathophysiology of major CNS disorders involving neurodegeneration, including Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), Huntington's disease (HD), and the most common form of motor neuron disease, amyotrophic lateral sclerosis (ALS). We also scrutinise the relationship of the NLRP3 inflammasome to intestinal microbiota alterations in these diseases. Both the NLRP3 inflammasome and P2X7R have been shown to play important roles in the pathogenesis and progression of these neurodegenerative diseases. However, most studies have focused on central nervous system (CNS) pathology, particularly within the brain, with comparatively less attention given to their contribution to gut pathology. Additionally, changes in the microbial ecosystems of the intestine have also been implicated in these disorders. However, the association between gut microbiota alterations and inflammasome activity in the pathology of these neurodegenerative disorders remains poorly understood. Therefore, further investigation is urgently needed to explore the microbiota-inflammasome-brain axis in these neurodegenerative conditions, in order to better understand their contribution to disease pathogenesis and progression, and identify novel therapeutic targets and new approaches to prevention and treatment.},

abstract = {BACKGROUND: In between episodes of (hypo) mania and major depression, people with bipolar disorder can experience ongoing low mood or mood instability, and these may also be present as part of cyclothymic disorder. This is a phase II evaluation of an adapted form of behavioural therapy (STABILISE) for inter-episode bipolar symptoms. The study aims to establish the feasibility and acceptability of the therapy and research procedures, including an economic component, to inform a future definitive trial.

METHODS: Patients will be randomised 1:1 to either Treatment as Usual (control arm) or Treatment as Usual plus STABILISE intervention (intervention arm). Follow up points will be at 14, 30 and 52 weeks post eligibility confirmation, with 30 weeks as the primary end point. We aim to recruit 60 individuals meeting diagnostic criteria for a Bipolar Spectrum Disorder, and reporting ongoing bipolar symptoms (low mood or mood instability) outside of a manic or severe depressive episode. Feasibility and acceptability will be examined through recruitment and retention rates, completion rates for the candidate primary outcome measures (PHQ9, ALS-SF, QoL.BD and BRQ) and feedback from participants on their experience of study participation and therapy. Proceeding to a definitive trial will be indicated if the following criteria are met: (i) trial participation is deemed, or can be made, sufficiently safe; (ii) recruitment rate indicates that larger-scale recruitment would be feasible (recruitment rate of at least two participants per month within at least one site, with mitigation plan if overall target sample size not met); (iii) for candidate primary outcome measure follow up data is available at 30 weeks from at least 75% of participants, or from between 55 and 74% with clear plan for improvement.

DISCUSSION: This study is a randomised, controlled feasibility trial that builds on an initial case series of the STABILISE approach. The findings will be used to establish whether a future, definitive trial is feasible and to refine the research procedures and therapy protocol.

Conditions such as Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), and frontotemporal dementia (FTD) share features of impaired microglial phagocytosis, chronic neuroinflammation, and metabolic dysregulation. These insights have prompted new therapeutic strategies targeting microglial function and emphasized the need for reliable biomarkers to monitor disease progression and treatment response. Well-established therapeutic targets, such as triggering receptor expressed on myeloid cells 2 (TREM2), progranulin (PGRN), and sortilin (SORT1), along with emerging candidates including LILRB4, P2Y6R, TAM receptors, and neuroinflammation-related markers, are discussed alongside novel blood, cerebrospinal fluid (CSF), and imaging biomarkers. Despite notable progress, many of these biomarkers remain restricted to preclinical studies and face translational challenges due to species-specific differences, lack of standardization, and clinical heterogeneity. Emerging technologies-including single-cell omics, spatial transcriptomics, and artificial intelligence (AI)-driven integration of multimodal data-offer new opportunities to align biomarker profiles with evolving disease states and improve patient stratification. Building on the model of companion diagnostics (CDx) in oncology, integrating multimodal biomarker strategies holds promise for guiding personalized interventions, improving clinical outcomes, and deepening our mechanistic understanding of microglial contributions across the neurodegenerative spectrum.},

Tofersen is an antisense oligonucleotide that induces SOD1 mRNA degradation. In the 28-week, placebo-controlled, multinational, phase III VALOR trial, intrathecally administered tofersen reduced plasma concentrations of neurofilament proteins (biomarker for neuro-axonal injury) and total SOD1 protein in cerebrospinal fluid in patients with SOD1 mutation-associated ALS. These reductions were sustained in a long-term, open-label extension study. The decline in functional outcomes was not significantly reduced with tofersen treatment compared with placebo in the 28-week phase III trial, although in the longer-term open-label study, early tofersen initiation was associated with slowed functional decline versus delayed tofersen initiation. Tofersen had an acceptable tolerability profile in clinical trials with a favourable benefit-to-risk balance. In summary, tofersen is a new disease-modifying therapy for patients with ALS attributed to an SOD1 mutation, offering reductions in levels of a biomarker associated with neurodegeneration and disease progression, with an acceptable tolerability profile.},

This study aimed to verify that tofacitinib can suppress NK cell cytotoxicity, investigate if immune cell profiles can predict responsiveness to tofacitinib, and assess the role of NK cell cytotoxicity in ALS progression.

METHODS: Primary NK cells were isolated from peripheral blood samples of ALS participants and healthy controls. NK cells were then co-cultured with target cancer cells, with or without tofacitinib, to assess their cytotoxic activity. Flow cytometry was used to generate immune profiles for each participant, based on 154 immune markers, to explore correlations with NK cell cytotoxicity and response to tofacitinib. The potential association between NK cell cytotoxicity and disease severity, as measured by the revised ALS Functional Rating Scale, was also assessed. All analyses were stratified by age and sex.

RESULTS: Tofacitinib effectively reduced the cytotoxicity of primary NK cells isolated from the blood of ALS participants (n = 80) and healthy controls (n = 71), with immune cell profiles correlating with the response to tofacitinib. However, NK cell cytotoxicity was lower in ALS participants compared to healthy controls and showed no association with ALS progression.

INTERPRETATION: These findings confirm that tofacitinib suppresses NK cell cytotoxicity, and that immune profiling may help identify treatment responder groups. However, further research is needed to fully understand the role and timing of NK cell activity in ALS pathogenesis.},

abstract = {BACKGROUND: High-power short-duration (HPSD) radiofrequency ablation (RFA) for atrial fibrillation (AF) treatment carries the risk of steam pops (SPs) due to rapid tissue heating. However, methods to predict impending SP during HPSD-RFA remain undefined.

OBJECTIVE: This study aims to establish a quantitative criterion for predicting SPs during HPSD-RFA.

METHODS: Retrospective analysis was performed on 489 patients undergoing HPSD-RFA for AF, focusing on corresponding RFA parameters in those who experienced SPs.

RESULTS: Among 1943 ablation lesions (ALs) delivered in 18 patients with SPs, 24 ALs had SP occurrence. Tip temperature, RFA duration, and ablation index were not significantly different between SP ALs and non-SP ALs. The mean contact force was significantly higher in SP ALs (12 g vs. 9, p < 0.001). All SPs adhered to the following criteria: impedance drop ≥8Ω during the first 4 s of RFA, impedance variability <5Ω within the first 4 s of RFA (24/24 vs. 79/247, p < 0.001), no events in the posterior wall of the left atrium, impedance drop ≥12Ω within 4-12 s. By halting delivery of RFA early with this finding in approximately five ALs per patient, the risk of SP complications could be significantly mitigated.

CONCLUSION: Monitoring impedance trends in the initial 4 s of HPSD-RFA can effectively predict impending SP occurrences. Automated algorithms should be developed to halt RFA delivery in this setting.},

abstract = {PURPOSE: Sleep disturbances are considered an early manifestation of Amyotrophic lateral sclerosis (ALS). However, sleep-disordered breathing (SDB) in ALS remains underexplored. The primary outcome of this study is to describe the clinical, functional and polygraphic characteristics of ALS patients with baseline SDB and to compare those with and without obstructive sleep apnea (OSA) in level III polysomnography (PSG) at diagnosis. Secondary outcomes included identification of baseline factors predictive of non-invasive ventilation (NIV) initiation/death during follow-up and assessing the role of level III PSG performed at the initial clinical evaluation in ALS prognosis regarding timing to NIV initiation and death.

METHODS: A cross-sectional study was conducted on 74 patients between September 2023 and September 2024. For the primary outcome, only patients that exhibited baseline SDB were included (45 patients). The population (45) was divided into 2 groups: Group 1 (n = 26; obstructive apnea/hypopnea index ≥ 5) and Group 2 (n = 19; obstructive apnea/hypopnea index < 5). For the secondary outcomes, all 74 patients were included regardless of sleep events.

RESULTS: Patients with OSA had a higher baseline body mass index (p = 0.03) and lower nocturnal average oxygen saturation (p = 0.03). A lower forced vital capacity (p < 0.001) and higher transcutaneous carbon dioxide (p = 0.005) at baseline were predictive of timing to NIV initiation.

CONCLUSIONS: Our study highlights the importance of performing respiratory functional testing and transcutaneous carbon dioxide assessment in ALS prognosis, regarding timing to NIV initiation. Although level III PSG is vital in the diagnosis and treatment of SDB, further studies are needed to clarify its role at disease onset and identify additional potentially predictors of timing to NIV initiation/death in ALS patients.},

Recent studies have reported that there are mutations at the T cell antigen-1 (TIA1) domain site in some ALS patients. TIA1 is a key component of stress granules (SGs), but its role and mechanism in ALS pathogenesis remain unclear. In this study, we found that TIA1 was upregulated in the motor cortex of postmortem ALS patients as well as in the motor cortex neurons of C9orf72-poly-GA mice (ALS mice). TIA1 knockout in the central nervous system (TIA1Nestin-CKO mice) alleviated motor neuron loss, neuroinflammation and motor dysfunction in C9orf72-poly-GA mice. Mechanistically, RNA-sequencing combined with the C9orf72-ALS/FTD patient (snRNA-seq) database revealed that mRNA of heat shock protein 70 (HSP70) family member genes such as HSPa1b were up-regulated in the motor cortex of TIA1Nestin-CKO ALS mice. We further found that TIA1-mediated SGs formation was increased during ALS pathogenesis, leading to HSP70 mRNA being sequestered into SGs. This reduced HSP70 expression, impairing the degradation of poly-GA aggregates by the UBQLN2-HSP70 pathway and exacerbating C9orf72-ALS progression. Taken together, these findings highlight a previously unrecognized role of TIA1-mediated SGs in promoting ALS pathogenesis by sequestering HSP70 mRNA, suggesting potential therapeutic targets for ALS treatment.},

Accurately predicting disease progression and survival is crucial for optimizing patient care, intervention planning, and informed decision-making.

METHODS: Data were gathered from the PRO-ACT database (4659 patients), clinical trial data from ExonHit Therapeutics (384 patients) and the PULSE multicenter cohort aimed at identifying predictive factors of disease progression (198 patients). Machine learning (ML) techniques including logistic/linear regression (LR), K-nearest neighbors, decision tree, random forest, and light gradient boosting machine (LGBM) were applied to forecast ALS progression using ALS Functional Rating Scale (ALSFRS) scores and patient survival over one year. Models were validated using 10-fold cross-validation, while Kaplan-Meier estimates were employed to cluster patients according to their profiles. To enhance the predictive accuracy of our models, we performed feature selection using ANOVA and differential evolution (DE).

RESULTS: LR with DE achieved a balanced accuracy of 76.05% on validation (ranging from 68.6% to 79.8% per fold) and 76.33% on test data, with an AUC of 0.84. With Kaplan-Meier's estimates, we identified five distinct patient clusters (C-index = 0.8; log-rank test p value ≤0.0001). Additionally, LGBM predictions for ALSFRS progression at 3 months yielded an RMSE of 3.14 and an adjusted R[2] of 0.764.

CONCLUSION: This study showcases the potential of ML models to provide significant predictive insights in ALS, enhancing the understanding of disease dynamics and supporting patient care.},

abstract = {Neurodegenerative diseases are a group of chronic diseases characterized by a gradual loss of neurons that worsens over time and dysfunction. These diseases are extremely harmful, not only affecting the physical health of the patients, but also having a serious impact on their quality of life. They mainly include Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), Amyotrophic lateral sclerosis (ALS), etc. Their pathogenesis is complex, and it is difficult for the existing treatments to effectively slow down the progression of the disease. In recent years, Mesenchymal Stem Cells (MSCs) have received widespread attention for their anti-inflammatory, immunomodulatory and neuroprotective properties. In this context, MSC-derived Extracellular Vesicles (MSC-EVs) have demonstrated unique therapeutic potential as a cell-free therapeutic strategy. MSC-EVs are rich in bioactive substances such as proteins, lipids, mRNAs and miRNAs, which can pass through the blood-brain barrier and be targeted to the diseased area to regulate neuronal survival, synaptic plasticity and neuroinflammatory responses. In addition, compared with stem cell therapy, MSC-EVs have the advantages of low immunogenicity, easy storage and transportation, and avoiding ethical controversies. However, their clinical application still faces challenges: standardized isolation and purification techniques have not been unified, vesicle loading efficiency and targeting need to be further optimized, and long-term safety needs to be systematically evaluated. This review focuses on the role of MSC-EVs in the development of neurological diseases and explores their possible dual roles, both favorable and unfavorable, in the context of neurological diseases. In addition, this review provides a review of current studies on EVs as potential biomarkers for the diagnosis and treatment of neurodegenerative diseases and provides a comprehensive review of the prospects and challenges of MSC-EVs in clinical applications.},

abstract = {The idea of using stem cell therapy to treat neurodegenerative diseases has undergone significant change over the years and has made significant progress recently. Neurotrophins, growth factors, and transcription factors regulate neural stem cell proliferation and differentiation. Disruption of these regulatory mechanisms, including negative feedback, can contribute to neurodegenerative diseases. Contemporary research highlights a growing global concern regarding diverse neurodegenerative disorders affecting both humans and animals. These conditions arise from neuronal cell death, axonal regeneration failure, and impairment of neuronal structure. Current pharmacological treatments primarily offer symptomatic relief without altering disease progression. Consequently, researchers are investigating innovative therapeutic strategies, with neural stem cell therapy emerging as a promising avenue. Adult neural stem cells, embryonic neural stem cells, and induced pluripotent stem cells represent potential cell sources, although challenges such as ethical considerations and technical limitations remain. The therapeutic application of neural stem cells holds significant promise for addressing neurodegenerative diseases, including Alzheimer's disease, stroke, amyotrophic lateral sclerosis, spinal cord injury, and multiple sclerosis. Neural stem cell therapy aims to replenish lost neurons and promote neural regeneration in these conditions. While clinical trials have demonstrated some success in improving cognitive and motor functions in individuals with neurodegenerative impairments, challenges such as immunological rejection, the identification of compatible cell sources, ethical concerns, treatment efficacy, and potential side effects necessitate thorough investigation before widespread clinical implementation. Despite these challenges, neural stem cell-based therapy offers substantial potential for revolutionizing the treatment of neurodegenerative diseases and central nervous system injuries. This paper, therefore, explores adult neurogenesis and the therapeutic potential of neural stem cells within the dynamic field of neurodegenerative disorders.},

abstract = {Neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and ALS are defined by the accumulation of misfolded and aggregated proteins, which impair cellular function and result in progressive neuronal death. This chapter examines the critical function of proteostasis-cellular protein homeostasis-in sustaining neuronal health and its disruption as a key factor in disease progression. Proteostasis is upheld by a complex array of mechanisms, which encompass molecular chaperones, the ubiquitin-proteasome system, autophagy-lysosomal pathways, and mitochondrial quality control. Impairment of these systems leads to protein misfolding and aggregation, resulting in toxic cellular environments that promote neurodegeneration. Novel therapeutic approaches focus on restoring proteostasis through the enhancement of cellular protein folding, degradation, and clearance mechanisms. This encompasses small molecule chaperones, gene therapy, RNA-based treatments, immunotherapy, autophagy inducers, and stem cell-based approaches, each addressing distinct components of the proteostasis network to mitigate or prevent disease progression. While these therapies show potential, challenges persist, such as possible side effects, selective targeting, and the efficacy of blood-brain barrier penetration. Personalized medicine and combination therapies customized to specific disease profiles are increasingly recognized for their potential to improve efficacy and safety. This chapter consolidates recent developments in therapies aimed at proteostasis, addresses the challenges encountered in clinical applications, and outlines potential future directions for transformative treatments. Ongoing research indicates that proteostasis modulation may significantly alter the course of neurodegenerative disease treatment, potentially enhancing patient outcomes and quality of life.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive degeneration of upper and lower motor neurons. This degeneration results in increasing muscle weakness, ultimately culminating in respiratory failure and death. Mutations in the fused in sarcoma (FUS) gene have been identified as a significant cause of ALS. Here, we present the case of a 40-year-old woman who exhibited right limb muscle weakness and atrophy as her initial symptom. Whole genome sequencing revealed a mutation in the FUS gene, specifically c.1450_1456delinsCCC (p.Tyr484Profs*44), leading to a diagnosis of ALS type 6 (ALS6). The c.1450_1456delinsCCC (p.Tyr484Profs*44) mutation is a frameshift mutation resulting from a non-triplet base deletion in the coding region of the FUS gene. This mutation is novel and has not been previously reported in China or internationally. Furthermore, the onset of muscle weakness and atrophy exclusively in the ipsilateral limb is very rare among ALS patients, and we have found no related reports. This case report aims to enhance medical professionals' understanding of the complexities associated with ALS caused by FUS gene mutations and the onset of ALS symptoms, thereby facilitating more accurate clinical diagnosis and treatment.},

abstract = {OBJECTIVE: Amyotrophic lateral sclerosis (ALS), a devastating neurodegenerative disease, poses a significant challenge for targeted treatment development. Accurate prediction of its progression is crucial for this endeavor.

METHODS: This study investigated deep learning methods for ALS progression prediction using the publicly available PRO-ACT dataset. Initially, machine learning models (XGBoost, LightGBM) and a deep learning sequential model were evaluated with default parameters, using R-squared (R2) and Root Mean Squared Error (RMSE) as performance metrics.

RESULTS: Notably, the deep learning model demonstrated superior predictive performance with default settings (RMSE: 4.565, R2: 0.716), followed by XGBoost (RMSE: 4.625, R2: 0.709) and LightGBM (RMSE: 4.596, R2: 0.716). Subsequently, hyperparameter optimization significantly enhanced the deep learning model's performance, achieving the highest prediction accuracy (RMSE: 4.511, R2: 0.718). Slight improvements were also observed for XGBoost (RMSE: 4.532, R2: 0.715) and LightGBM (RMSE: 4.551, R2: 0.716). Furthermore, the optimized XGBoost model demonstrated exceptional classification performance in distinguishing between bulbar and limb onset ALS, with a sensitivity of 100%, specificity of 97.44%, accuracy of 97.96%, F1-score of 95.96%, Matthews Correlation Coefficient (MCC) of 94.12%, and an Area Under the Curve (AUC) of 0.9550. Feature importance analysis with optimized XGBoost identified ZBTB2P1 as the most influential feature, followed by RNF181, with WASH9P being the least influential among the top eight.

CONCLUSIONS: These findings convincingly demonstrate the potential of optimized XGBoost and deep learning for ALS progression prediction and classification, particularly with optimized parameters. This approach offers significant potential for early risk stratification, personalized treatment planning, enhanced prognostic communication, diagnostic support, streamlined disease monitoring, and improved clinical decision-making, ultimately contributing to better patient outcomes and potentially reducing ALS-related mortality.},

abstract = {A pathological hallmark of ALS is the abnormal accumulation of misfolded proteins (e.g., TDP-43) and enlarged endoplasmic reticulum (ER), indicating ER stress. To resolve this stress, cells initiate the Unfolded Protein Response (UPR). However, unresolved stress leads to apoptosis. In ALS, UPR activation fails to resolve proteostasis impairment. UPR activation modulators, among them Sephin1, reduce protein aggregates and improve motor neuron survival in ALS models. We demonstrate that following glutamate intoxication, Sephin1 increases motor neuron survival by reducing mitochondria ROS production and extranuclear TDP-43. Sephin1 reduces abnormal splicing because of TDP-43 nuclear loss of function following oxidative stress. In SOD1[G93A] mice, Sephin1 treatment decreases TDP-43 in triton-insoluble fraction, improving motor neuron survival in spinal cord. Sephin1 improves motor neurons survival, motor function and survival of mutated TDP-43 transgenic zebrafish. Sephin1 improves motor neuron survival in ALS models by reducing TDP-43 cytoplasmic mislocalization and its toxicity. These findings open new therapeutic opportunities for Sephin1 in neurodegenerative pathologies with TDP-43 proteinopathy, including ALS.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is a prevalent condition characterized by motor neuron loss and skeletal muscle paralysis. Despite being associated to mutations in over 40 genes, its etiology remains elusive without a cure or effective treatment. ALS, historically considered a motor neuron disease, is defined today as a multisystem disorder involving non-neuronal cell types, including early muscle pathology independent of motor neuron degeneration (dying back hypothesis), thus skeletal muscle actively contributes to disease pathology, making it a viable therapeutic target for ALS. Our previous research has shown that boron transporter NaBC1 (encoded by the SLC4A11 gene), after activation co-localizes with integrins and growth factor receptors synergistically enhancing muscle repair. Here we investigate the effects of injectable alginate-based hydrogels for controlled local borax release in Amyotrophic Lateral Sclerosis muscle. Treated mice showed improved motor function, prolonged survival, and activation of essential muscle metabolic pathways, leading to enhanced muscle repair and reduced atrophy and inflammation. Interestingly, local muscle repair activation provided retrograde neuroprotection by preserving motor neurons and reducing neuro-inflammation. This study highlights the role of muscle tissue in ALS pathology, supporting its targeting with NaBC1-based therapies for muscle regeneration.},

abstract = {BACKGROUND: Patients with amyotrophic lateral sclerosis (ALS) often experience spasticity, which can severely affect their ability to perform basic activities like standing and walking, potentially diminishing their already compromised quality of life. Botulinum toxin type A (BTX-A) is a first-line drug for spastic management. However, there are limited reports on its effectiveness in reducing muscle tone among ALS patients, with scarcely any related research conducted in China. We conducted the clinical observation and follow-up study through the relevant ethical post (ChiCTR2200061794). Clinical registration was on July 2, 2022. All participants provided written informed consent.

CASE PRESENTATION: We report two cases of middle-aged male patients, both diagnosed with ALS, who presented with symptoms such as limb stiffness and walking limitation due to increased muscle tone in the lower limbs. Based on the spasticity of the patient's lower limbs, the corresponding target muscles were selected for BTX-A treatment under ultrasound guidance, and the patients were evaluated on relevant functional scales before injection (baseline, T0) and at three follow-up visits (T1: 2 weeks, T2: 4 weeks, T3: 8 weeks).

CONCLUSION: Appropriate BTX-A injected into the target muscles could effectively depress the spasticity of ALS patients without apparent side effects.},

abstract = {The metabolic modulator trimetazidine (TMZ) is an antianginal recently found to improve skeletal muscle performance in mice models of sarcopenia and of amyotrophic lateral sclerosis (ALS). The mechanism underlying the effect of TMZ on locomotor activity has been proposed to rely on its ability to enhance metabolic efficiency with a consequent improvement of myogenesis and of neuromuscular junction (NMJ) and muscle function. However, although promising and therefore under clinical trials, the mechanism of action of TMZ has not been clearly disclosed; here we hypothesized that it might involve the modulation of neuronal Ca[2+] flows. We studied the effect of TMZ on Ca[2+] dynamics in vivo, by using the transgenic zebrafish line Tg(neurod1:GCaMP6f) in which the neuronal expression of the Ca[2+] indicator GCaMP allows to visualize Ca[2+] dynamics in neurons of zebrafish larvae. By this elegant tool, we demonstrated, for the first time, that TMZ promotes an increase of intracellular Ca[2+] transients in zebrafish spinal neurons likely enhancing motor neuron firing, which correlates with enhanced motor performance induced by this drug. Even though elevated intracellular Ca[2+] levels have often been associated to neurotoxicity, it is unclear if the neuronal excitability features in some neuro-muscular disorders are compensatory or pathological. Therefore, this newly reported effect of TMZ which transiently and selectively enhances spinal neuron firing deserves to be further detailed and taken into account when the possible repurposing of this drug is proposed for the treatment of neuro-muscular disorders.},

abstract = {INTRODUCTION/AIMS: On/Off dosing of intravenous (IV) edaravone and edaravone oral suspension was US Food and Drug Administration (FDA)-approved for Amyotrophic Lateral Sclerosis (ALS) treatment. Placebo-controlled trials showed that IV edaravone slows the rate of physical functional decline in patients with ALS. Here, the impact of edaravone oral suspension on function and survival was assessed.

METHODS: Edaravone oral suspension was investigated in clinical trials MT-1186-A01/A02/A03/A04. Patients from Studies MT-1186-A02/A04 (prespecified analysis) and Studies MT-1186-A01/A02/A03/A04 (post hoc analysis) were propensity score matched 1:1 on 10 baseline variables with historical Pooled Resource Open-Access ALS Clinical Trials (PRO-ACT) placebo patients (not receiving active investigational treatment in their trials) to assess the impact of edaravone oral suspension on function and survival.

RESULTS: In the prespecified analysis, 78 edaravone oral suspension-treated patients from Studies MT-1186-A02/A04 demonstrated a survival benefit versus 78 matched PRO-ACT placebo patients (p = 0.005). Baseline risk-adjusted hazard ratio showed an 84% decreased risk of death in edaravone oral suspension versus PRO-ACT placebo patients (p = 0.005). ALS Functional Rating Scale-Revised (ALSFRS-R) total score change from baseline at Week 48 was -8.4 points for edaravone oral suspension versus -14.1 points for PRO-ACT placebo patients (p < 0.001). In the post hoc analysis, patients from Studies MT-1186-A01/A02/A03/A04 (n = 210) propensity score matched to PRO-ACT placebo patients (n = 210) showed statistically significantly longer time to death and smaller ALSFRS-R change from baseline at Week 48; restricted mean survival time showed a 7.3-month improvement (p < 0.001).

DISCUSSION: This suggests edaravone oral suspension significantly increases survival time and decreases physical functional decline versus PRO-ACT placebo patients.},

MMN is often misdiagnosed due to similarities in clinical symptoms with conditions including amyotrophic lateral sclerosis (ALS), making diagnosis and treatment challenging. Objectives: This study assessed patient characteristics, treatment patterns, and the economic burden of MMN in the United States. Methods: Using the Optum Research Database, this retrospective analysis included patients with ≥1 diagnostic or nondiagnostic medical claim with an MMN diagnosis code between 2016 and 2020 (date of first diagnosis-related claim =index date), and continuous enrollment for 12 months preindex and postindex. Patients with MMN within this group were identified using more specific criteria; ≥2 MMN nondiagnostic claims separated by ≥30 days, with no subsequent ALS diagnosis during follow-up. All patients who did not meet these criteria were included in the MMN-mimic cohort. Outcomes included treatment patterns, differential diagnoses, healthcare utilization, and costs. Results: Of 904 patients identified, 37% had MMN and 63% had an MMN-mimic condition. Patients with MMN were significantly younger than patients in the MMN-mimic cohort (mean, 64.9 vs 66.8 years; P = .047). At preindex, significantly more patients with MMN received MMN-related medications than patients in the MMN-mimic cohort (20.5% vs 9.0%, respectively; P < .001). Intravenous immunoglobulin (IVIG) was the most common MMN-related medication. At postindex, more patients with MMN used IVIG (28.0%) compared with preindex (16.4%). In the 12 months preindex and postindex, >70% of patients had ≥1 differential diagnosis. The MMN cohort had higher all-cause total costs than the MMN-mimic cohort (mean preindex, 58 974 v s 48 132, respectively [P = .100]; mean postindex, 74 187 v s 50 652 [P = .002]); they also had significantly higher MMN-related healthcare costs (mean preindex, 23 625 v s 12 890 [P = .011]; mean postindex, 39 521 v s 11 938 [P < .001]). Discussion: This study showed that most patients with initial MMN diagnoses had an alternative disorder after subsequent evaluation/follow-up, and patients with MMN incurred higher costs. Many patients with MMN did not receive IVIG, suggesting that undertreatment or misattribution of diagnosis codes are common. Conclusions: Further education is needed regarding accurate diagnosis of MMN to ensure patient access to guideline-recommended treatment.},

abstract = {Plant-derived cannabinoids, including Δ[9]-THC, cannabinol, and Sativex-like combinations, have shown neuroprotection in preclinical ALS models. However, minor phytocannabinoids like cannabidiolic acid (CBDA) remain unexplored. This study evaluated the neuroprotective effects of CBDA, cannabidivarin, CBD, Δ[9]-THC, and Δ[9]-tetrahydrocannabidivarin in Prp-hTDP-43(A315T) transgenic male mice from early symptomatic (day 65) to advanced stages (day 90). CBDA proved the most effective, improving motor coordination (rotarod test) and reducing neuronal cell death, gliosis, microglial reactivity, and pro-inflammatory mediators in the spinal cord. A dose-response study confirmed that 10 mg/kg CBDA improved motor performance and preserved motor neurons, while lower doses were less effective and higher doses caused toxicity. Flow cytometry revealed a shift from an M1 proinflammatory to an M2 anti-inflammatory phenotype in microglial cells after CBDA treatment, mirroring effects in BV2 cells exposed to LPS. Comparing CBDA with riluzole (standard ALS therapy), CBDA showed superior neuroprotection, except for rotarod performance, where no improvement was observed. A combination of CBD and riluzole failed to enhance efficacy and even weakened microglial response benefits. In conclusion, CBDA was the most effective of the five phytocannabinoids studied and outperformed riluzole in ALS models. These findings support further clinical evaluation of CBDA for ALS treatment.},

abstract = {Despite advances in understanding neurodegenerative disease mechanisms, effective treatments remain elusive. Extracellular vesicles (EVs), key mediators of intercellular communication within the central nervous system (CNS), are increasingly recognized for their involvement in the pathogenesis of neurodegenerative disorders like Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) and Huntington's disease (HD). In vivo studies demonstrate EVs' crucial role in maintaining CNS homeostasis, modulating neuroinflammatory responses, and influencing tissue repair and regeneration following injury, thereby impacting disease progression and recovery. Their unique properties, including small size and ability to cross the blood-brain barrier (BBB), position them as promising candidates for both biomarkers and therapeutics in CNS diseases. This review delves into the significant impact of neuroinflammation on neurodegenerative conditions, specifically focusing on the multifaceted contributions of EVs and their intricate interplay with the inflammatory landscape. We explore EV biogenesis, cargo composition, diverse roles in neuroinflammation (including intercellular communication and neuroprotection), their potential as biomarkers and drug delivery vehicles across the BBB for diagnosis or treatment of neuroinflammation implemented neurodegenerative diseases.},

abstract = {Dysregulated autophagy and copper/zinc superoxide dismutase (SOD1) protein aggregation play a crucial role in amyotrophic lateral sclerosis (ALS). Here, we used stably transfected NSC34 motor neuron-like cells: (1) SOD1[G93A] mutants (G93A), (2) wild-type SOD1 (WT) controls, and (3) empty vector (EV) controls to observe the effects of fisetin. Pharmacological autophagy inhibition (Bafilomycin A1, 40 nM) and nuclear factor erythroid 2-related factor 2 (Nrf2) gene silencing (siRNA transfection) were employed to dissect molecular pathways. Protein aggregation dynamics and autophagy markers (LC3, p62/SQSTM1) were quantified through immunofluorescence and immunoblotting. SOD1[G93A] models exhibited impaired autophagic flux evidenced by elevated LC3-II and p62 levels, correlating with increased detergent-insoluble SOD1 aggregates. Fisetin treatment (1-10 μ M) dose-dependently reduced both soluble and aggregated SOD1[G93A] protein, concomitantly with restored autophagic flux. Mechanistically, fisetin promoted nuclear translocation while decreasing cytoplasmic Nrf2. After administration of an autophagy inhibitor and interference with Nrf2, the regulation of fisetin on p62 and mutant hSOD1 protein was inhibited. Our findings demonstrate that fisetin ameliorates mutant SOD1 proteotoxicity through coordinated activation of Nrf2-mediated autophagy pathways, suggesting therapeutic potential for SOD1-associated ALS pathologies.},

Recent advances in gut microbiome research have spotlighted postbiotics and psychobiotics as innovative therapeutic strategies targeting the gut-brain axis to alleviate neurodegenerative symptoms and slow disease progression. Postbiotics, which are metabolites and cellular components released by probiotic bacteria, and psychobiotics, a class of probiotics with potential mental health benefits, offer novel approaches to neuroprotection. This chapter examines the ways in which postbiotics and psychobiotics modulate inflammation, oxidative stress, neurotrophic factors, and gut barrier integrity to provide neuroprotective effects. We review scientific research that highlights the efficacy of specific microbial strains and their metabolites in enhancing cognitive function and reducing neurodegeneration. In addition, we explore the consequences of diet and specific nutrition on strengthening the therapeutic results of these medications. The purpose of this chapter is to provide a detailed analysis of the existing data supporting the use of postbiotics and psychobiotics in both the prevention and management of neurological diseases. By integrating perspectives from microbiology, neurology, and clinical nutrition, we highlight the potential of these interventions to enhance patient outcomes and quality of life. In addition, we discuss the translational limitations and future research approaches required to successfully transition these microbiome-based treatments from the laboratory to clinical practice, emphasizing the importance of a holistic and personalized approach in combating neurodegenerative diseases.},

This article evaluates the study by Li et al, which investigates the links between insomnia, anxiety, and depression while examining the mediating role of cognitive failures and the moderating effect of neuroticism. The study employed a cross-sectional design with 1011 participants, using validated scales to measure insomnia severity, neuroticism, cognitive failures, and mental health indicators. Li et al found that approximately 40% of participants exhibited symptoms of anxiety, depression, and insomnia, with most cases being mild. The results demonstrated that cognitive failures play a mediating role in the relationship between insomnia and both anxiety and depression. Furthermore, neuroticism moderated the relationship between insomnia and cognitive failures, with a stronger effect observed in individuals with lower levels of neuroticism. These findings underscore the importance of considering personality traits and cognitive processes in understanding mental health outcomes. This study emphasizes the critical need for interventions aimed at reducing cognitive failures and enhancing emotional stability to mitigate the impact of insomnia on mental health. Strategies to improve sleep quality, boost cognitive resilience, and regulate emotional responses could significantly enhance individuals' mental well-being. Moreover, integrating personality assessments into mental health services could facilitate more effective and personalized interventions. This article provides an original perspective on the effects of the coronavirus disease 2019 pandemic on global mental health. The content of the article addresses the complex relationships between sleep disorders, cognitive function losses, and neuroticism in light of data compiled from existing literature and current research. In addition, how these relationships have deepened during the pandemic and the effectiveness of proposed treatment methods for these phenomena are discussed in comparison with previous studies. The arguments in the article offer new perspectives and suggestions aimed at filling gaps in the literature, and make an important contribution to both clinical practice and public health policies. Li et al's study provides a comprehensive framework for understanding the connections between insomnia, cognitive failures, and neuroticism, as well as their influence on anxiety and depression. The findings offer valuable implications for public health strategies, emphasizing the necessity of holistic approaches to address post-pandemic mental health challenges.},

abstract = {A 3D motor neuron (MN) spheroid has been developed to investigate neurodegenerative and neuromuscular junction (NMJ) disease.

In this study, to enhance neural network formation, a biohybrid MN spheroid composed of neural cells/reduced graphene oxide (rGO)/human umbilical vein endothelial cells (HUVECs) was generated for the first time and applied to 3D biosensing system for MNJ disease. By incorporating rGO and HUVECs at the onset of human neural stem cell (hNSC) culture, rGO and HUVECs were evenly distributed within MN spheroid generated by differentiation of hNSC, which improved oxygen- and nutrient- supply by reduction of core necrosis, and enhanced neurogenesis. The fabricated biohybrid MN spheroid improved neural network formation and electrophysiological signal. This method was also applied to generate biohybrid cerebral organoids from human induced pluripotent stem cells (hiPSCs), emphasizing its versatility for diverse 3D neural models. Then, a 3D NMJ biosensing system was fabricated by positioning the biohybrid MN spheroid with muscle bundles to evaluate its utility in neuromuscular disease modeling. Biohybrid MN spheroids generated from induced pluripotent stem cells of sporadic amyotrophic lateral sclerosis (ALS) patients were used to make NMJ. Reduced contraction of the connected muscle bundle due to ALS could be restored by upon treatment with the bosutinib, ALS drug, demonstrating the potential use for drug screening. The method to generate biohybrid spheroid can be applied to generation of various biohybrid brain organoids, and the proposed 3D NMJ biosensing system can be used to drug screening of diverse neuromuscular diseases.},

METHODS: An online cross-sectional survey was distributed to UK healthcare professionals involved in cough and/or secretion management care in people with ALS.

RESULTS: A total of 113 responses were analyzed, over half were from physiotherapists (52%). The majority (71%) of respondents reported a role managing saliva and secretions. Just under two thirds (60%) routinely assessed cough and almost all (89%) routinely assessed secretions. Healthcare professionals reported reduced confidence assessing secretions compared with cough and very few (5%) used validated secretion outcome measures. Participants reported lower confidence implementing all treatment strategies than recommending them. Multiple barriers to care were identified, including access to specialist care and equipment, education and skills training and a lack of evidence-based care guidelines.

CONCLUSION: Cough and secretion management is complex and involves numerous professional groups. There is a need for clinical and educational interventions that address knowledge and skill gaps in managing cough and secretion issues, which will help increase healthcare professionals' confidence in assessing and treating these complex problems.},

The integration of multi-omics data reveals complex molecular mechanisms underlying ALS heterogeneity, potentially identifying novel therapeutic targets. We highlight current gene therapy strategies, including antisense oligonucleotides (ASOs), RNA interference (RNAi), and CRISPR/Cas9 gene editing systems, alongside advanced delivery methods for crossing the blood-brain barrier.

With no curative treatment, ALS care depends on the early and sustained integration of palliative care to address complex and evolving needs. Nurses play a pivotal role in this process, yet their lived experiences remain underexplored. This study aimed to synthesize qualitative evidence on nurses' experiences in ALS care, with a focus on emotional, ethical, and palliative dimensions.

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

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

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

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

A novel combination of celecoxib (CXP) and ciprofloxacin (CIP) has recently been used to enhance both motor performance and CNS cell morphology, alterations in the rate of disease progression, quality of life, and survival, which passed phase IIb RCT study. Celecoxib is classified as a non-steroidal anti-inflammatory drug; ciprofloxacin is a fluoroquinolone antibiotic that has a synergistic effect for the treatment of ALS, which is a severe neurological disorder. A new sustainable, simple, sensitive, and environmentally friendly synchronous spectrofluorimetric approach (SSF) was established to simultaneously estimate celecoxib and ciprofloxacin in pure form and biological fluids. The approach depends on synchronous fluorescence spectroscopy, where CXP and CIP were detected at 364 and 438 nm, correspondingly, using Δλ of 80-nm utilizing sodium dodecyl sulphate (SDS) micellar system, which considerably improved synchronous fluorescence intensity. The approach was validated and revealed excellent linearity with concentrations varying from 10 to 10,000 and 5 to 20,000 ng/mL for CXP and CIP; correspondingly, CXP and CIP showed extremely low limits of detection (LODs) 0.58-0.24 ng/mL, which guarantee the sensitivity of the proposed approach. The suggested approach was successfully implemented to analyze the co-administered pharmaceuticals in their pure form and actual human plasma after concurrent oral administration of both drugs, which may be employed in an inquiry on the pharmacokinetics and bioavailability of human plasma to the new coming PrimeC pharmaceutical formulation. Ultimately, the method's remarkable greenness was proved by evaluating its greenness profile using various assessment strategies. The findings revealed that the SSF approach is a sustainable and environmentally friendly analytical approach.},

abstract = {Gene silencing therapy is an effective treatment for amyotrophic lateral sclerosis (ALS) patients carrying mutations in the superoxide dismutase-1 (SOD1) gene aiming to reduce noxious forms of SOD1 in the central nervous system (CNS). The normal steady-state level of SOD1 protein in human CNS is therefore of interest but is contested. In this work we have analyzed SOD1 protein content, total protein content, and SOD1 enzymatic activity in six areas of the CNS as well as in four peripheral tissues from sporadic and familial ALS patients and non-ALS controls. Our results show that SOD1 in the human CNS constitutes around 100 μg/g wet weight corresponding to about 0.16% of the total protein in the studied areas. Of the peripheral tissues analyzed, kidney and erythrocytes contain roughly equal amounts, liver higher, and skeletal muscle lower levels of SOD1 compared to the CNS. This data shows SOD1 protein levels around 10 times lower compared to previously published figures. However, SOD1 can still be considered an abundant protein considering that > 12 000 proteins are expressed in human cells. There was no difference in SOD1 protein content between sporadic or familial ALS patients and control individuals. The level and activity of SOD1 are not deviating in the areas of the CNS that are most vulnerable to ALS. Instead, insufficient control of SOD1 structure and aggregation could be important factors behind the vulnerability of motor areas to SOD1 proteotoxicity.},

The author assessed about a thousand ESCC Chinese patients' samples for ACVR1C SNPs in a hospital-based cohort study using the ligation detection reaction method. Further, the hypothesis was tested using appropriate statistical genetic models and stratified analysis. ACVR1C SNPs can help assess ESCC susceptibility stratification and provide valuable information for individual diagnosis and treatment of ESCC patients. In order to account for confounding variables, find genuine SNP-disease relationships, boost statistical power, and make biological interpretation easier, it is imperative that genetic association studies of ESCC incorporate pertinent clinical aspects.},

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

Sarcoidosis is an inflammatory disease affecting multiple organs, with neurological complications occurring in 5-10% of patients. Only isolated cases of this extremely rare combination of the two diseases have been reported.

METHODS: We present the case of a 45-year-old man diagnosed with ALS after a 2-year history of progressive upper limb weakness who was incidentally found to be affected by thoraco-abdominal lymphadenopathy. The biopsy confirmed the co-presence of sarcoidosis. We also make a systematic review of the literature of this rare combination.

RESULTS: The patient showed stabilization of the neurological condition and the pneumological disease after administration of immunosuppressive treatment.

CONCLUSION: Our case report and literature review highlight peculiar clinical characteristics of this extremely rare combination of diseases, deepening the understanding of this peculiar phenotype.},

abstract = {Neurodegenerative diseases are a group of illnesses characterized by the gradual deterioration of the central nervous system, leading to a decline in patients' cognitive, motor, and emotional abilities. Neuroinflammation plays a significant role in the progression of these diseases. However, there is limited research on therapeutic approaches to specifically target neuroinflammation. The role of T lymphocytes, which are crucial mediators of the adaptive immune response, in neurodegenerative diseases has been increasingly recognized. This review focuses on the involvement of T lymphocytes in the neuroinflammation associated with neurodegenerative diseases. The pathogenesis of neurodegenerative diseases is complex, involving multiple mechanisms and pathways that contribute to the gradual degeneration of neurons, and T cells are a key component of these processes. One of the primary factors driving neuroinflammation in neurodegenerative diseases is the infiltration of T cells and other neuroimmune cells, including microglia, astrocytes, B cells, and natural killer cells. Different subsets of CD4+ T cells, such as Th1, Th2, Th17, and regulatory T cells, can differentiate into various cell types and perform distinct roles within the neuroinflammatory environment of neurodegenerative diseases. Additionally, CD8+ T cells, which can directly regulate immune responses and kill target cells, also play several important roles in neurodegenerative diseases. Clinical trials investigating targeted T cell therapies for neurodegenerative diseases have shown that, while some patients respond positively, others may not respond as well and may even experience adverse effects. Targeting T cells precisely is challenging due to the complexity of immune responses in the central nervous system, which can lead to undesirable side effects. However, with new insights into the pathophysiology of neurodegenerative diseases, there is hope for the establishment of a solid theoretical foundation upon which innovative treatment strategies that target T cells can be developed in the future.},

abstract = {RNA therapeutics present a disruptive technology that has changed the drug discovery and manufacturing landscape, which established itself more prominently upon the recent COVID-19 pandemic. RNA therapeutics encompass diverse molecules like antisense oligonucleotides (ASOs), small interfering RNAs (siRNAs), microRNAs (miRNAs), RNA aptamers, and messenger RNAs (mRNAs), which can function through different mechanisms. RNA therapeutics are witnessing expanding applications across a range of diseases, notably in the treatment of neurological disorders. For instance, ASO therapies like nusinersen for spinal muscular atrophy and eteplirsen for Duchenne muscular dystrophy exemplify successful RNA therapeutic strategies. Emerging ASO treatments for Huntington's disease and amyotrophic lateral sclerosis are also promising, with ongoing clinical trials demonstrating significant reductions in disease-associated proteins. Still, delivery of these molecules remains a pivotal challenge in RNA therapeutics, especially for ASOs in penetrating the blood-brain barrier to target neurological disorders effectively. Nanoparticlebased formulations have emerged as leading strategies to enhance RNA stability, reduce immunogenicity, and improve cellular uptake. Despite these advances, significant hurdles remain, including optimizing pharmacokinetics, minimizing off-target effects, and ensuring sustained therapeutic efficacy. Regulatory frameworks are evolving to accommodate the unique challenges of RNAbased therapies, including ASOs with efforts underway to establish comprehensive guidelines for RNA therapeutics, yet there are also sustainable manufacturing issues that need to be considered for long-term feasibility. By addressing these challenges, RNA therapeutics hold immense potential to revolutionize treatment paradigms for neurological disorders. Looking forward, the future of RNA therapeutics in neurology appears promising but requires continued interdisciplinary collaboration and technological innovation.},

abstract = {INTRODUCTION: Plasmodium vivax is the predominant cause of malaria in the Greater Mekong Subregion. To ensure safe treatment with primaquine, point-of-care glucose-6-phosphate dehydrogenase (G6PD) testing was rolled out in Cambodia at the health facility level, although most malaria patients are diagnosed in the community. The current study aims to explore the acceptability and feasibility of implementing community-level G6PD testing in Cambodia.

METHODS: Semistructured interviews and focus group discussions (FGD) were conducted. Across eight study sites in three provinces, 142 respondents, including policymakers, programme officers, healthcare providers and patients, participated in 67 interviews and 19 FGDs in 2022 and 2023. Data were analysed thematically using an adapted framework derived from Bowen et al's feasibility framework and Sekhon et al's acceptability framework.

RESULTS: All stakeholders attributed value to the intervention. Acknowledging an intervention's different values can help discern policy implications for an intervention's successful implementation. Building and maintaining confidence in the device, end users, infrastructure and health systems were found to be key elements of acceptability. In general, health centre workers and village malaria workers (VMWs) had confidence that VMWs could conduct the test and administer treatment given appropriate initial training, monthly refresher training and the test's repeated use. More is required to build policymakers' confidence, while some implementation challenges, including the test's regulatory approval, stability above 30°C and cost, need to be overcome.

CONCLUSION: Implementation of G6PD testing at the community level in Cambodia is an acceptable and potentially feasible option but requires addressing implementation challenges and building and maintaining confidence among stakeholders.},

abstract = {With the gradual advancement of research methods and technologies, various biological processes have been identified as playing roles in the pathogenesis of neurodegenerative diseases. However, current descriptions of these biological processes do not fully explain the onset, progression, and development of these conditions. Therefore, exploration of the pathogenesis of neurodegenerative diseases remains a valuable area of research. This review summarizes the potential common pathogeneses of Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, frontotemporal lobar dementia, and Lewy body disease. Research findings have indicated that several common biological processes, including aging, genetic factors, progressive neuronal dysfunction, neuronal death and apoptosis, protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, axonal transport defects, and gut microbiota dysbiosis, are involved in the pathogenesis of these six neurodegenerative diseases. Based on current information derived from diverse areas of research, these biological processes may form complex pathogenic networks that lead to distinctive types of neuronal death in neurodegenerative diseases. Furthermore, promoting the regeneration of damaged neurons may be achievable through the repair of affected neural cells if the underlying pathogenesis can be prevented or reversed. Hence, these potential common biological processes may represent only very small, limited elements within numerous intricate pathogenic networks associated with neurodegenerative diseases. In clinical treatment, interfering with any single biological process has proven insufficient to completely halt the progression of neurodegenerative diseases. Therefore, future research on the pathogenesis of neurodegenerative diseases should focus on uncovering the complex pathogenic networks, rather than isolating individual biological processes. Based on this, therapies that aim to block or reverse various targets involved in the potential pathogenic mechanisms of neurodegenerative diseases may be promising directions, as current treatment methods that focus on halting a single pathogenic factor have not achieved satisfactory efficacy.},

abstract = {Lung volume recruitment (LVR) has been proposed as a treatment to maintain respiratory health in patients with neuromuscular diseases who frequently develop restrictive ventilatory impairment due to muscle weakness. LVR applies noninvasive mechanical pressure techniques to maintain and improve pulmonary and chest wall compliance and to preserve vital capacity. Various methods of LVR have been developed, which can be classified into two types: the stacked-breath method and the single-breath method. Mechanical insufflation-exsufflation (MI-E) is one approach categorized under the single-breath method. Although the clinical use of pressure settings in MI-E varies, inspiratory pressure levels around 40 cmH2O are sometimes applied in practice. However, such settings may result in patient discomfort and raise safety concerns. Given the limited clinical guidance available, it may be more appropriate to determine individualized settings based on each patient's impairment level, pulmonary mechanics, and tolerance. This case report describes such an approach to LVR using the single-breath method with MI-E in a patient with amyotrophic lateral sclerosis (ALS). To determine the optimal inspiratory pressure, three parameters were assessed at each pressure level: expiratory volume, subjective perception of lung expansion, and immediate subjective effects following inspiration. As the patient reported discomfort at 30 cmH2O, the final inspiratory pressure was set at 25 cmH2O. This level of inspiratory assistance led to improvements in vocal loudness and alleviated breathlessness during speech. These positive effects contributed to the patient's acceptance of the intervention and its continued use after discharge to home care. This case highlights the importance of tailoring LVR settings to optimize effectiveness, patient comfort, and safety, based on pulmonary mechanics, bedside volume assessment, and patient-reported respiratory status.},

Thus, monoclonal antibodies (mAbs) are being developed to target the pathological forms of this protein. To improve mAb exposure within the central nervous system, a potent anti-TDP-43 mAb, ACI-5891, was generated as a vectorized full-length antibody (vmAb) and evaluated for brain delivery using adeno-associated virus 9 (AAV9). Among the expression cassettes explored, the selected construct utilized an internal ribosome entry site (IRES), which produced high expression yields in vitro (>200 mg/L) with comparable quality, binding and functional properties to the conventionally produced mAb. A single intracisternal administration of vmAb ACI-5891 demonstrated a broad brain distribution and sustained expression (i.e., months) in the serum, cerebrospinal fluid and brain of mice. In a mouse model of ALS/FTD, treatment with a vmAb reduced the amount of pathological phospho-TDP-43 in neurons by 58% and 68% when expressed either using a ubiquitous promoter or a brain-selective promoter, respectively. This innovative approach sufficiently delivers effective immunotherapy with a single dose and illustrates the enormous potential of using vectorized antibodies to target neuropathology, including TDP-43 in patients suffering from ALS, FTD and other TDP-43 proteinopathies.},

Methods: Patients with a probable or definite ALS diagnosis were randomized to receive twice daily oral doses (for 12 weeks) of Usnoflast (25 mg, 50 mg, or 75 mg) or placebo. The primary outcome was the change in ALS functional rating scale-revised (ALSFRS-R) total score from baseline to week 12. Secondary outcomes were assessment of PK, change in slow vital capacity (SVC) and serum and cerebrospinal fluid (CSF) levels of neurofilament light (NfL) chain from baseline to week 12, and safety up to 12 weeks. Results: Total 24 patients were enrolled; 71% of those who received Usnoflast had the drug above therapeutic concentration in CSF. In the modified intent-to-treat (mITT) population, least square mean changes (ANCOVA) in ALSFRS-R total score from baseline to week 12 were -1.91 for Usnoflast 25 mg, -3.84 for Usnoflast 50 mg, 0.52 for Usnoflast 75 mg, and -2.26 for placebo arm. Though not significant (p > 0.05), compared with placebo, Usnoflast 75 mg demonstrated a difference of 2.78 (mITT) and 3.28 (per-protocol) in ALSFRS-R total score. Statistical non-significant differences were also observed in changes of SVC% and CSF NfL levels. Usnoflast was well-tolerated at tested doses, and there was no treatment-emergent serious adverse event or death during the study duration. Conclusion: Usnoflast 50 and 75 mg doses were well-tolerated in ALS patients, providing rationale for further studies of Usnoflast in ALS.},

However, its high market value and regional variations have led to frequent adulteration, highlighting the need for rapid, non-destructive methods for authentication, geographical traceability, and quality assessment. This study employed portable Raman spectroscopy combined with Partial Least Squares Discriminant Analysis (PLS-DA) and Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) to differentiate camellia oil from other edible oils and evaluate its thermal and photo-oxidative stability. PLS-DA, based on VIP-selected spectral variables, effectively distinguished camellia oil, with Raman bands near 1250 cm[-1] and 1650 cm[-1] contributing significantly. A unique peak at 1525 cm[-1], observed in samples from Gongcheng, Guangxi, was associated with carotenoids and served as a potential marker for geographical traceability. MCR-ALS modeling revealed significant reductions in the 1650 cm[-1] and 1525 cm[-1] peaks when temperatures exceeded 150 °C, indicating degradation of unsaturated fatty acids and carotenoids. Under UV exposure, the 1525 cm[-1] peak declined sharply and nearly disappeared after 24 h, suggesting rapid carotenoid degradation via photooxidation. Extended UV treatment also affected the 1650 cm[-1] peak and led to oxidative product accumulation. Overall, this study demonstrates the feasibility of integrating Raman spectroscopy with chemometric analysis for efficient oil classification, traceability, and stability monitoring, offering a valuable tool for food quality control and market supervision.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease associated with damage to motor neurons and leading to severe muscle weakness and, eventually, death. Over the past decade, understanding of the key pathogenetic links of ALS, including glutamate-mediated excitotoxicity and oxidative stress, has significantly advanced. This review considers the recent evidence on molecular mechanisms of these processes, as well as the therapeutic strategies aimed at their modulation. Special attention is paid to antiglutamatergic and antioxidant drugs as approaches to the ALS pathogenetic therapy.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by the progressive degeneration of motor neurons, for which therapeutic strategies and pharmacological interventions remain limited. Disruption of the blood-spinal cord barrier (BSCB) has been identified as a significant factor that may exacerbate motor neuron damage. Tissue inhibitor of metalloproteinase-1 (TIMP1), a molecule known for its dual roles in inhibiting matrix metalloproteinase (MMP) activity and exerting cytokine-like effects via receptor interactions, has been demonstrated to ameliorate endothelial barrier damage in various diseases. Here, we explored the potential of TIMP1 to restore BSCB integrity as a strategy to slow the ALS progression. Specifically, the expression of TIMP1 or its mutant variant AlaTIMP1, which lacks MMP-inhibitory activity, in spinal cord microvascular endothelial cells (SCMECs) prior to disease onset significantly reduces BSCB leakage in mice with ALS, thereby alleviating motor function deficits and delaying disease progression. Additionally, TIMP1 expression restores the expression of junctional complexes in SCMECs, as demonstrated in both in vivo and in vitro ALS models. Mechanistic studies revealed that TIMP1 suppresses ALS injury-induced integrin β1 activation independent of MMP inhibition, blocking downstream Rac1 translocation to the membrane to form a complex with NOX2. The inhibition of NOX2 activity reduces ROS-induced cytoskeletal remodeling, consequently stabilizing overall junctional alignment and preserving the BSCB integrity. Overall, our findings elucidate an MMP-independent mechanism through which TIMP1 regulates BSCB integrity in ALS context, suggesting that TIMP1 could serve as a novel tool for the treatment of ALS, particularly for prophylactic treatment in patients with familial ALS.},

abstract = {Calcium dysregulation, caused by pathological activation of ryanodine receptors, contributes to motor neuron degeneration, motor dysfunction, and muscle weakness in SOD1-G93A transgenic amyotrophic lateral sclerosis (ALS) mice. This study investigates the therapeutic efficacy of intranasally administered dantrolene nanoparticles, a ryanodine receptor antagonist, on motor neuron function, muscle strength, spinal cord degeneration, and survival outcomes. Male and female C57BL/6SJLF1 non-transgenic control and SOD1-G93A ALS transgenic mice were assigned to one of three experimental groups: 1) NO TX: No treatment control; 2) IN-DAN: Intranasal administration of dantrolene in the Ryanodex formulation vehicle (RFV), at a dosage of 5mg/kg, administered daily from ages 90-120 days; 3) IN-VEH: Intranasal administration of RFV alone (as a vehicle control), following the same dosing schedule as the IN-DAN condition. Body weight and general motor function were monitored weekly, with survival recorded daily throughout the treatment period. At the treatment conclusion, neurological function was comprehensively evaluated using a standardized neurological scoring system. Motor coordination and balance were assessed using the balance beam test (beam widths of 12 mm and 6 mm) and the rotarod test. Muscle strength was evaluated by measuring grip force using the Kondziela inverted screen test. After behavioral testing, spinal cord tissues were collected for analysis. The levels of neurofilament light chain (NFL), a skeletal neuron protein, and spinal cord weight were determined to measure spinal cord degeneration. Compared to non-transgenic control mice, SOD1-G93A mice exhibited significantly elevated neurological scores, indicating severely impaired neurological function. This deterioration was robustly and significantly ameliorated by IN-DAN treatment by 90% (P<0.0001). Similarly, ALS mice demonstrated impairments in motor coordination and balance on the beam balance test, with dramatic and significant increases in crossing time and the number of foot slips. These impairments were greatly and significantly mitigated by IN-DAN treatment, by 78% in crossing time (P<0.0001) and 84% in the number of slips (P<0.0001) on the 12 mm-wide beam, but not by the vehicle control. ALS mice demonstrated progressive body weight loss as well, which was similarly reversed by IN-DAN treatment, but not by the vehicle control. Muscle strength, as measured by grip force, was significantly reduced in ALS mice but robustly preserved IN-DAN treatment, which prevented the decrease by 213% (P<0.0001), while the vehicle control had no effect. Spinal cord weight was significantly reduced in ALS mice, a trend reversed by intranasal dantrolene nanoparticle treatment, but not by the vehicle control. Survival analysis revealed that 100% of control mice survived through the 30-day treatment period (up to 120 days of age), while survival in untreated or vehicle-treated ALS mice dropped to 67%. In contrast, ALS mice treated with intranasal dantrolene nanoparticles demonstrated a significantly improved survival rate of 89%. Thus, intranasal dantrolene nanoparticle treatment significantly and robustly improved neurological outcomes in SOD1-G93A ALS mice, inhibiting neurological impairment, motor dysfunction, balance deficits, and muscle weakness. These improvements were associated with a marked inhibition of spinal cord weight loss. Additionally, dantrolene treatment reversed body weight loss and significantly improved survival probability in ALS mice.},

abstract = {Advances in virtual staining and spatial omics have revolutionized our ability to explore cellular architecture and molecular composition with unprecedented detail. Virtual staining techniques, which rely on computational algorithms to map molecular or structural features, have emerged as powerful tools to visualize cellular components without the need for physical dyes, thereby preserving sample integrity. Similarly, spatial omics enable the mapping of biomolecules across tissue or cell surfaces, providing spatially resolved insights into biological processes. However, traditional dye-based staining methods, while widely used, come with significant limitations. In this context, Raman spectroscopy offers a robust, label-free alternative for probing molecular composition at a high resolution. We present a novel algorithm that reconstructs super-resolved Raman images by extracting spectral patterns from surrounding pixels, enabling detailed, label-free visualization of cellular structures. By employing Raman spectroscopy in conjunction with chemometric tools such as principal component analysis (PCA), multivariate curve resolution-alternating least squares (MCR-ALS), and artificial neural network (ANN), we performed a quantitative analysis of key biomolecular components, including collagen, lipids, glycogen, and nucleic acids, and classify the different cancer cell lines with an accuracy of nearly 99%. This approach not only enabled the identification of distinct molecular fingerprints across the different cancer types but also provided a powerful tool for understanding the biochemical variations that underlie tumor heterogeneity. This innovative combination of virtual staining, spatial omics, and advanced chemometrics highlights the potential for more accurate diagnostics and personalized treatment strategies in oncology.},

abstract = {INTRODUCTION: Botulinum toxin injections into the salivary glands inhibit saliva production by reducing the release of acetylcholine at the parasympathetic nerve terminals within the salivary gland. The phase 3 study reported here assessed the safety, tolerability, and effectiveness of repeated cycles of rimabotulinumtoxinB (RIMA) injections in adults with troublesome sialorrhea.

METHODS: In this phase 3, open-label multicenter study, 187 adult participants with troublesome sialorrhea due to Parkinson disease (65.8%), amyotrophic lateral sclerosis (13.9%), and other etiologies (20.3%) received up to 4 cycles of RIMA treatment (3500 U every 11-15 weeks).

RESULTS: Participants (69% male, 31% female; mean age 64.1 years) had sialorrhea for a mean of 3.2 years at baseline with a mean Unstimulated Salivary Flow Rate (USFR) of 0.63 ± 0.49 g/min. During the first treatment cycle, RIMA significantly reduced the mean±standard deviation (SD) USFR from baseline to week 4 by - 0.34 ± 0.37 g/min (p < 0.0001), and efficacy was maintained through week 13 (- 0.14 ± 0.29 g/min; p < 0.0001). Reductions were maintained at subsequent injection cycles 2-4, with mean absolute USFRs at weeks 4 and 13 of each cycle similar to those of cycle 1. Most adverse events (AEs) were mild, and the most commonly reported AEs in each cycle that were considered to be treatment-related were dry mouth (≤ 15.5% participants/cycle) and dental caries (≤ 6.0% participants/cycle).

CONCLUSION: This study demonstrates that RIMA 3500 U safely reduces saliva production over repeated treatment cycles through 1 year, thereby supporting its utility in the management of troublesome sialorrhea in adults.

abstract = {BACKGROUND: Weed tolerance to herbicides poses a major threat to agricultural production. Aegilops tauschii has promising prospects for genetic development; however, the fact that this plant is invasive in China and other countries is often ignored owing to its pronounced adaptability. Among the current acetolactate synthase (ALS) inhibitors, only mesosulfuron-methyl (MM) can control A. tauschii, and pyroxsulam (P) is ineffective. However, a knowledge gap remains regarding differences in sensitivity of A. tauschii to these two ALS inhibitors.

RESULTS: We hypothesized that differences in sensitivity of A. tauschii to the ALS inhibitors MM and P are mediated by metabolic enzymes. Whole-plant experiments showed that the P450s inhibitor 1-Aminobenzotriazole (ABT) significantly increased the sensitivity of A. tauschii to P compared with MM. In A. tauschii, the P metabolism rate was higher than that of MMl, as detected by liquid chromatography with tandem mass spectrometry. Transcriptome sequencing and quantitative real-time polymerase chain reaction identified seven differentially expressed P450s after P and MM treatments, three of which were upregulated after P treatment and were unaffected by MM. AtCYP99A2 reduced plant sensitivity to P by metabolizing P without affecting MM by overexpressing it in Arabidopsis and inducing in vitro protein expression.

CONCLUSION: To the best of our knowledge, this is the first report on P450 involvement in A. tauschii sensitivity to two ALS-inhibitor herbicides. This study deepens current understandings of A. tauschii and facilitates subsequent screening of specific metabolic enzyme inhibitors to be used as synergists in combination with herbicides, which will provide new avenues for weed control. © 2025 Society of Chemical Industry.},

The patient with traumatic AS-related cervical fractures underwent a two-stage surgery. The stage I surgery involved a posterior atlantoaxial reduction and fixation surgery combined with C5/C6/T1/T2 posterior pedicle screw fixation plus C6/C7 decompression. One week later, C6/C7 anterior cervical corpectomy decompression and fusion (ACCF) with long anterior plate stabilization combined with iliac crest bone graft transplantation was performed for stage II surgery. The patient recovery observed during follow-up was satisfactory. Nine-month postoperative radiological images revealed fracture union of the upper and lower cervical spine with optimal reduction of the atlantoaxial segment. In conclusion, lower cervical ALs with simultaneous upper cervical C1/C2 fractures in the AS are very rare. Posterior C1-C2 fixation combined with C6-C7 AL corpectomy/fusion and posterior pedicle screw fixation may offer a desirable alternative approach for this complex case of cervical trauma. During treatment, complete decompression, effective reduction, and potent stabilization can comprehensively improve the clinical prognosis.},

In contrast to Scheufle et al's report of 90%-100% failure rates with early surgical approaches, Tanaka and Yoshii's protocol achieved universal healing despite delayed diagnoses in 25% of cases. Central to this success is the systematic integration of high-resolution computed tomography for early diagnosis and dynamic monitoring of trabecular bone regeneration, significantly reducing missed diagnoses and guiding personalized immobilization timelines. The patient-centered strategy-allowing temporary splint removal during low-risk activities-balanced fracture stability with joint mobility preservation, avoiding post-treatment stiffness. However, limitations such as small sample size (n = 16), selection bias, and insufficient long-term functional data (e.g., grip strength, return-to-sport metrics) underscore the need for comparative trials. Emerging trends, including adjunct therapies like low-intensity pulsed ultrasound and biologics (e.g., teriparatide), are proposed to accelerate healing while minimizing immobilization risks. This work redefines conservative fracture management paradigms, emphasizing innovation without compromising efficacy. Overall, this assessment deepens our understanding of the conservative management of hook fractures and provides evidence-based insights for improved clinical decision-making.},

Synaptosome-Associated Protein-25 (SNAP-25) plays a key role in triggering involuntary saliva secretion. This study aimed to identify SNAP-25-targeting bovine milk-derived peptides to mitigate sialorrhea, using computational and quantum atomistic simulation approach. Among 8559 bovine milk-derived peptides, 8499 were non-toxic, 7749 non-allergenic, 911 with blood-brain barrier crossing potential, and 175 with cell-penetrating capabilities. Using HAPPENN program, 20 non-hemolytic peptides were screened, while PeptideRanker predicted two physiologically active peptides. Protein-peptide docking followed by de novo structural modeling showed that CMPTFQFFK has a stronger inhibitory affinity (- 7.45 kcal/mol) for SNAP-25 than botulinum toxin. Additionally, dynamic simulations, free energy and quantum chemical studies confirmed the stability of CMPTFQFFK's with SNAP-25. Our study recommends CMPTFQFFK as a potential inhibitor of SNAP-25 for sialorrhea treatment, with further in vitro testing needed to confirm efficacy.},

One method, called the Master Reset Protocol, is thought to stimulate the vagus nerve system, impacting heart rate, digestion and other vital systems.

PURPOSE: We used the Master Reset Protocol on a subject experiencing paroxysmal Atrial Fibrillation (AFib) to assess whether this treatment might be effective in reversing a cardiac arrhythmia.

SUBJECT AND METHODS: A single subject is reported in this Case Report. The subject is a 62-year-old healthy, athletic male, 6'2″ tall, 165 lbs. with a good diet and is not obese nor has other exacerbating underlying conditions related to heart disease. The subject experiences arrhythmia approximately 1-2 times per month lasting generally 3 or more days per the subject. The Master Reset Method was initiated within 12 hours of arrhythmia onset, and arrhythmia before and after treatment was confirmed through subject observation and confirmed with pulse readings. A total of ten treatments were conducted over 7 months.

RESULTS: Reversal of arrhythmia was confirmed during or within 24 hours of treatment with DC application for all 10 treatments (100%). Two of the more severe cases of AFib required two treatments on the same day with confirmed reversal of AFib.

CONCLUSION: Treatment with Direct Current suggests a good correlation with reversal of arrhythmia. Further studies are planned to determine if similar, regular, treatments can be effective in preventing arrhythmia.},

abstract = {Amyotrophic lateral sclerosis (ALS) degenerates both upper and lower motor neurons. Most patients with ALS require respiratory support due to deterioration of their respiratory muscles. Mechanical insufflation-exsufflation (MI-E) is one option that can help patients with weak cough strength to clear the airway, and it may potentially increase survival time. Another option is lung volume recruitment training (LVRT), a technique commonly used to maintain lung and chest wall flexibility. However, it requires specific equipment, such as one-way valves, to be applied to patients with ALS who undergo invasive mechanical ventilation with tracheostomy. Only limited studies have indicated the effectiveness of LVRT for patients with ALS. Moreover, no study is currently available on the effect of combining LVRT with MI-E. As the disease progresses, treatment options become increasingly limited, making it crucial to explore new therapeutic approaches for patients at the advanced stage. Here, we examined the effects of a combination of LVRT and MI-E in a 74-year-old female patient with ALS who had survived under invasive mechanical ventilation for nine years. We measured tidal volume (TV) and dynamic lung compliance (Cdyn) as respiratory parameters three months before and after the initiation of the combined therapy. Following the intervention, TV improved from 750.15 L/min (standard deviation (SD) ± 34.60) to 859.14 L/min (SD ± 75.63), and Cdyn increased from 24.18 cmH2O (SD ± 2.84) to 26.54 cmH2O (SD ± 2.92). These results suggest that MI-E combined with LVRT may improve lung compliance even in patients with ALS receiving long-term invasive mechanical ventilation.},

Neurofilament light chain (NfL) is an established therapy response biomarker in ALS as superoxide dismutase1 (SOD1)-ALS patients treated with the antisense oligonucleotide tofersen show a decrease in NfL. In this study, we assess cTnT levels in SOD1-ALS at baseline and during tofersen treatment.

METHODS: cTnT was analyzed at baseline and during tofersen treatment in 23 SOD1-ALS patients at two specialized ALS centers in Germany and compared to a control cohort of 74 ALS patients without SOD1 variants.

RESULTS: cTnT levels increased in the control ALS cohort over time (p < 0.0001) but not in the tofersen group (p = 0.36). Creatine kinase (CK) and CK-MB levels did not show significant changes over time. The median monthly increase of cTnT was 0.045 points (IQR 0.02-0.08) in the control ALS cohort and 0.01 points (IQR -0.01-0.03) in the tofersen group (p = 0.0013). A significantly lower fold change in cTnT levels was observed in the tofersen-treated cohort (median 1.2; IQR 0.77-1.59) relative to the control group (median 1.89; IQR 1.35-2.75) (p = 0.0003). Nine (39%) patients treated with tofersen experienced a reduction in cTnT levels.

DISCUSSION: In this study, we describe a response signal of cTnT to tofersen treatment, which supports the value of cTnT as an independent biomarker in ALS. These results contribute to the notion that cTnT may provide additional value as a progression and treatment response biomarker in ALS complementary to NfL and warrant further investigation.},

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

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

abstract = {INTRODUCTION/AIMS: Edaravone intravenous (IV) and oral suspension have been shown to have similar pharmacokinetics, safety, and slowing of functional decline in patients with amyotrophic lateral sclerosis (ALS). Study MT-1186-A01 indicated that edaravone oral suspension was well-tolerated over 48 weeks, with no new safety concerns identified relative to existing safety data of IV edaravone, including Study MCI186-19. The aim of this study was to assess the long-term safety and tolerability of edaravone oral suspension in patients with ALS.

METHODS: Study MT-1186-A03 (NCT04577404) was a phase 3, open-label, multi-center, extension study that evaluated the long-term safety of edaravone oral suspension over an additional 96 weeks in patients with ALS who have completed the initial 48 weeks of Study MT-1186-A01, for a total of up to 144 weeks of treatment. Patients received a 105-mg dose of edaravone administered in treatment cycles identical to the approved edaravone on/off dosing schedule. Patients had definite, probable, probable-laboratory-supported, or possible ALS.

RESULTS: In Study MT-1186-A03, edaravone oral suspension was well tolerated with no new safety concerns. The most common treatment-emergent adverse events (TEAEs) were fall, muscular weakness, dyspnea, constipation, and dysphagia. These TEAEs were consistent with the safety profile for edaravone from previous clinical trials.

DISCUSSION: These results help establish the long-term safety and tolerability profile of edaravone oral suspension.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative disease characterized by muscle weakness and atrophy, with limited treatment options. The accumulation of misfolded proteins, such as misfolded superoxide dismutase 1 (mSOD1), contributes significantly to neuronal degeneration in ALS. Therapies targeting misfolded proteins represent a promising strategy. Baicalein, a flavonoid compound with neuroprotective properties, has shown efficacy in clearing misfolded proteins and improving behaviors in rodent models of Alzheimer's and Parkinson's diseases. However, its effects in ALS remain largely unexplored. This study demonstrated that baicalein treatment reduced total and misfolded SOD1 protein levels in both soluble and insoluble fractions of a motor neuron cell line overexpressing mutant SOD1. Baicalein also reduced intracellular SOD1 aggregates in cultured motor neurons transfected with SOD1/G93A, preserving neurite length. In an ALS mouse model expressing the SOD1/G93A transgene, baicalein treatment decreased mSOD1 aggregation, increased spinal motor neuron density, and reduced neuromuscular junction denervation. Furthermore, baicalein partially improved motor behaviors, as assessed by the rotarod test. These findings highlight baicalein's potential as a therapeutic agent for ALS, targeting intraneuronal misfolded proteins to ameliorate pathological changes and preserve motor function.},

abstract = {OBJECTIVE: To investigate the relationship between short-interval intracortical inhibition (SICI), short-interval intracortical facilitation (SICF) and amyotrophic lateral sclerosis (ALS) phenotype, using threshold-tracking transcranial magnetic stimulation (TMS).

METHODS: A new paired-pulse TMS protocol was applied to 49 patients with ALS and 49 age-matched healthy controls. Motor evoked potentials (MEPs) were recorded from first dorsal interosseus muscle, while paired pulses were delivered at interstimulus intervals (ISI) of 1.0, 2.5 or 3.0 ms, with stimuli related to the resting motor threshold for a 200 µV MEP. For each ISI, 6 SICI and 3 SICF pulse pairs with different conditioning stimuli were randomised and interleaved with test-alone stimuli.

RESULTS: ALS phenotypes were characterised as Pyramidal (n = 12, with prominent upper motor neuron signs), Classic (n = 20, with limb onset), or Bulbar (n = 17). Compared with healthy controls, Bulbar patients had significantly less inhibition at all ISIs, while SICI in Pyramidal patients was normal, and in Classic patients intermediate. The only SICF abnormalities independent of the changes in SICI were less facilitation in Pyramidal patients at ISIs 1 and 3 ms.

CONCLUSION: Changes in SICI and SICF depend on ALS phenotype.

SIGNIFICANCE: ALS phenotypes should be matched between treatment and placebo arms of clinical trials.},

abstract = {OBJECTIVES: Prediction models for post-stroke mortality can support medical decision-making. Although numerous models have been developed, external validation studies determining the models' transportability beyond the original settings are lacking. We aimed to assess the performance of two prediction models for post-stroke mortality in Berlin, Germany.

DESIGN: We used data from the Berlin-SPecific Acute Treatment in Ischaemic or hAemorrhagic stroke with Long-term follow-up (B-SPATIAL) registry.

SETTING: Multicentre stroke registry in Berlin, Germany.

PARTICIPANTS: Adult patients admitted within 6 hours after symptom onset and with a 10th revision of the International Classification of Diseases discharge diagnosis of ischaemic stroke, haemorrhagic stroke or transient ischaemic attack at one of 15 hospitals with stroke units between 1 January 2016 and 31 January 2021.

PRIMARY OUTCOME MEASURES: We evaluated calibration (calibration-in-the-large, intercept, slope and plot) and discrimination performance (c-statistic) of Bray et al's 30-day mortality and Smith et al's in-hospital mortality prediction models. Information on mortality was supplemented by Berlin city registration office records.

RESULTS: For the validation of Bray et al's model, we included 7879 patients (mean age 75; 55.0% men). We observed 763 (9.7%) deaths within 30 days of stroke compared with 680 (8.6%) predicted. The model's c-statistic was 0.865 (95% CI: 0.851 to 0.879). For Smith et al's model, we performed the validation among 1931 patients (mean age 75; 56.2% men), observing 105 (5.4%) in-hospital deaths compared with the 92 (4.8%) predicted. The c-statistic was 0.891 (95% CI: 0.864 to 0.918). The calibration plots of both models revealed an underestimation of the mortality risk for high-risk patients.

CONCLUSIONS: Among Berlin stroke patients, both models showed good calibration performance for low and medium-risk patients and high discrimination while underestimating risk among high-risk patients. The acceptable performance of Bray et al's model in Berlin illustrates how a small number of routinely collected variables can be sufficient for valid prediction of post-stroke mortality.},

We here investigate whether RNA G4s play a role in TDP43 condensation in biophysical and cellular models. We find that G4s modulate TDP43 aggregation in vitro and condensation in multiple cell types, including yeast, HEK293T, and motor-neuron-like NSC-34 cells. In yeast cells, treatment with G4s causes increased TDP43 accumulation in cells before cellular death. In HEK293T cells expressing TDP43, incubation with G4-binding small molecules causes an increase in G4 stability that also stabilizes TDP43 and reduces TDP43 condensation induced by proteasomal or oxidative stress. Finally, in NSC-34 cells overexpressing exogenous TDP43, we show that G4s co-localize with TDP43 condensates under stress conditions, and treatment with G4-binding small molecules decreases TDP43-mediated toxicity. Together, these findings suggest exploring treating protein misfolding diseases by targeting specific RNA structures such as G4s.},

SOD1 mutations have a significant role in the pathophysiology and fast behavior of protopathic proteins in ALS illness. The E100K mutation may be useful in uncovering the pathogenic mechanism of SOD1 associated with ALS. According to several studies, giving small molecule inhibitors made from polyphenolic flavonoid compounds may be a viable treatment strategy for neurological conditions. Using molecular docking and MD simulations, we have identified a potential flavonoid drug that may successfully inhibit SOD1's amyloidogenic activity. Puerarin, Fisetin, and Peonidin provided intriguing pharmacological hints during the initial screening of flavonoids. The Fisetin-E100K complex had a larger residual energy contribution and substantial binding than other flavonoid compounds. The findings showed that, unlike other materials, Fisetin increased the structural stability, hydrophobicity, and flexibility of the mutant while reducing the amount of β-sheets. Furthermore, to distinguish aggregation in the mutant (unbound/bound) states, we displayed modifications in the free energy landscape (FEL). As a result, Fisetin was identified as having therapeutic potential against the E100K, which might make it a viable pharmacological option for the creation of inhibitors that lower the chance of ALS death.},

Placebo-controlled clinical trials showed IV edaravone slows the rate of physical functional decline. This study evaluated whether investigational daily dosing displayed superior efficacy vs. approved on/off dosing of edaravone oral suspension, and assessed safety and tolerability, over 48 weeks in patients with ALS.

METHODS: Study MT-1186-A02 (NCT04569084) was a multicenter, phase 3b, double-blind, parallel group, superiority study that randomized patients to edaravone oral suspension (105-mg dose) administered Once Daily or the same edaravone oral suspension dose administered according to the approved On/Off regimen including placebo to mimic daily drug dosing. Patients had definite or probable ALS, baseline forced vital capacity ≥ 70%, and baseline disease duration ≤ 2 years. The primary endpoint was a combined assessment of function and survival (CAFS) at week 48, which included change in ALS Functional Rating Scale-Revised (ALSFRS-R) and time to death.

RESULTS: CAFS at week 48 indicated Once Daily dosing did not show a statistically significant difference vs. approved on/off dosing (p = 0.777). Both dosing regimens provided comparable change from baseline ALSFRS-R total score to week 48 (least squares mean difference: 0.27 [95% CI -1.43 to 1.97]). Edaravone oral suspension was well tolerated, and no new safety concerns were identified in either group.

DISCUSSION: Daily edaravone oral suspension did not show superiority and had equivalent safety and tolerability vs. the approved On/Off regimen, reinforcing the appropriateness of the approved dosing regimen.},

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

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

abstract = {BACKGROUND: As a key inflammatory factor, the nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) inflammasome plays a crucial role in neuroinflammation and the progression of neurodegenerative diseases. Dysregulation of NLRP3 signaling can trigger various inflammatory responses in the brain, contributing to the development of neurodegenerative diseases such as ischemic stroke, vascular dementia (VaD), Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). Therefore, the NLRP3 signaling pathway is a promising therapeutic target for the treatment of neurodegenerative diseases, including VaD.

METHODS: In this study, we investigated the therapeutic effects of a synthetic sulfonylurea NLRP3 inhibitor, AMS-17, in a VaD mouse model using bilateral common carotid artery stenosis (BCAS) and elucidated the underlying mechanisms. All mice were randomly divided into three groups: Sham, VaD + Vehicle, and VaD + AMS-17. Cognitive function was assessed using the Y-maze and Morris water maze (MWM) on the 50th day after BCAS. Brain sections and blood serum samples were collected for biomarker analysis and immunohistochemistry. Neurodegeneration, expressions of the molecules involved in the NLRP3 signaling pathways, tight junction proteins, and myelination were assessed using western blotting and immunofluorescence (IF). The levels of Interleukin-1 beta (IL-1β), Tumor Necrosis Factor-alpha (TNF-α) and Interleukin-4 (IL-4) in the blood were measured using ELISA.

RESULTS: AMS-17 treatment improved cognitive function, enhanced blood-brain barrier (BBB) integrity, and promoted remyelination in VaD mice. Additionally, AMS-17 reduced neurodegeneration and decreased the expression of NLRP3 and its associated proteins, Apoptosis-associated speck-like protein (ASC), and cleaved caspase-1 in the brain. It also lowered pro-inflammatory TNF-α and IL-1β levels, while increasing the anti-inflammatory IL-4 level in the blood.

CONCLUSIONS: The findings of this study provide the first promising evidence for the use of AMS-17 in VaD treatment in mice. This study introduces AMS-17 as a novel chemical scaffold with NLRP3 inhibitory activity, which can be further developed for the treatment of VaD in humans.

abstract = {BACKGROUND: Acute leukemias (ALs), including acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), are heterogeneous diseases characterized by different phenotypic, genetic, and molecular alterations that can guide treatment decisions. ALs harboring lysine methyltransferase 2A gene translocation (KMT2t), previously known as mixed-lineage leukemia, are associated with high rates of relapsed or refractory (R/R) disease. Revumenib, a first-in-class oral menin inhibitor, has shown improved clinical outcomes in patients with R/R KMT2At ALs.

OBJECTIVE: To estimate, using a budget impact model (BIM), the financial impact of introducing revumenib for the treatment of adult patients with R/R KMT2At ALs on the formulary of a hypothetical US 1-million-member commercial health plan.

METHODS: The BIM compared scenarios with or without revumenib and the resulting impact on commercial US third-party payers over a 3-year time horizon. Although no other therapies specifically targeted for R/R KMT2At ALs were approved during BIM development, 11 additional pharmacotherapies for R/R ALs (5 for AML and 6 for ALL, not including revumenib) were included as treatment options in the model. Clinical data included adverse event (AE) rates, duration of treatment, time to subsequent treatment, and survival outcomes. Cost inputs (USD 2024) included in the model comprised drug acquisition and administration, grade 3 or greater AEs, treatment-related supportive care and monitoring, subsequent treatment, and end-of-life costs. The differential cost per member per month (PMPM) was estimated. One-way sensitivity analyses varying the costs of drug acquisition and toxicity by ±20% and scenario analyses varying uptake of revumenib and epidemiology inputs, as well as excluding costs related to supportive care and posttreatment discontinuation, were performed.

RESULTS: An estimated 1.7 adult patients (AML, 1.1; ALL, 0.6) were treatment eligible annually. Estimated 3-year total plan costs without and with revumenib were $2,146,564 and $2,126,919, respectively, for savings of -$19,646. Including revumenib was estimated to yield a differential PMPM cost of -$0.0005 over 3 years. The total number of grade 3 or greater AEs was lower over 3 years (10.82 vs 10.99, respectively) in the plan with revumenib vs without. Sensitivity and scenario analyses validated the robustness of the model.

CONCLUSIONS: The BIM demonstrated that including revumenib in a formulary for adult patients with R/R KMT2At ALs was approximately cost neutral, offering patients access to a targeted treatment with potential for improved clinical outcomes.},

abstract = {OBJECTIVE: Treatment of refractory ventricular fibrillation (rVF) is a clinical challenge. If rVF is still present after standard advanced life support (ALS) guideline care, including amiodaron administration, other therapeutic options might be necessary. Based on the available evidence and expertise, our Helicopter Emergency Medical Service (HEMS) team developed a local practice guide for the prolonged resuscitation of patients in rVF and implemented this as standard HEMS care in March 2022.

METHODS: This database study contains all patients treated with our local practice guide during out of hospital cardiac arrest (OHCA) with rVF beyond the fifth regular ALS shock-block. This local practice HEMS treatment algorithm consisted of, among others, cessation of epinephrine and alternating administration of esmolol and norepinephrine combined with enoximone. Data were derived from the HEMS database and the treating hospitals. Primary outcome was the return of spontaneous circulation. Secondary outcome was defined as survival to hospital discharge and cerebral performance. This outcome was compared to the literature to analyze for inferiority of treatment.

RESULTS: In a 21-month period, HEMS was 761 times deployed for OHCA. Nineteen patients were treated with the local practice guide, nine patients (47%) were admitted to hospital with return of spontaneous circulation. Median resuscitation time was 22min. Hospital survival with good neurology was achieved in 42% vs 17% as expected. Exact Clopper-Pearson and logistic regression analysis revealed non-inferiority of the local practice guide. Withholding epinephrine was achieved in 84% of patients. A total of 79% and 90% of patients received esmolol and norepinephrine/enoximone mixture, respectively. Alternative defibrillation positions were indicated in 18 patients but applied in only 6 (33%).

CONCLUSION: In patients with persisting VF despite prolonged advanced life support care, a multifaceted bundle of care approach shows promising results and warrants further research. Alternative drug administrations were found to be substantially easier to achieve compared to alternative defibrillation positions.},

abstract = {Formation of cytoplasmic inclusions (CIs) of TDP-43 and FUS, along with DNA damage accumulation, is a hallmark of affected motor neurons in Amyotrophic Lateral Sclerosis (ALS). However, the impact of CIs on DNA damage response (DDR) and repair in this pathology remains unprobed. Here, we show that CIs of TDP-43 and FUS[P525L], co-localizing with stress granules, lead to a dysfunctional DDR activation associated with physical DNA breakage. Inhibition of the activity of the DDR kinase ATM, but not of ATR, abolishes DDR signaling, indicating that DNA double-strand breaks (DSBs) are the primary source of DDR activation. In addition, cells with TDP-43 and FUS[P525L] CIs exhibit reduced DNA damage-induced RNA synthesis at DSBs. We previously showed that the two endoribonucleases DROSHA and DICER, also known to interact with TDP-43 and FUS during small RNA processing, contribute to DDR signaling at DSBs. Treatment with enoxacin, which stimulates DDR and repair by boosting the enzymatic activity of DICER, restores a proficient DDR and reduces DNA damage accumulation in cultured cells with CIs and in vivo in a murine model of ALS. In Drosophila melanogaster, Dicer-2 overexpression rescues TDP-43-mediated retinal degeneration. In summary, our results indicate that the harmful effects caused by TDP-43 and FUS CIs include genotoxic stress and that the pharmacological stimulation of the DNA damage signaling and repair counteracts it.},

abstract = {INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a devastating illness that leads to muscle weakness and death usually within around 3 years of diagnosis. People with ALS (pwALS) often lose weight due to raised energy requirements and symptoms of the disease presenting significant challenges to taking adequate oral diet, with those who lose more weight being at a greater chance of earlier death. There is also some evidence to suggest that a higher calorie diet may benefit the disease course in pwALS, but further research is needed.

METHODS AND ANALYSIS: Two armed, parallel group, superiority, open labelled, randomised controlled trial, with internal pilot, to assess the effectiveness of an early high calorie diet on functional outcomes in ALS, comprising two treatment arms: (1) standard care, (2) standard care with additional active management using the OptiCALS complex intervention to achieve a high calorie diet (initially randomised 1:1, then 1:2 following a protocol amendment). Using a food first approach, pwALS will be encouraged and supported to follow a diet that meets an individualised calorie target from food before prescribing oral nutritional supplements. 259 pwALS will be recruited from up to 20 ALS centres across the United Kingdom and Ireland and followed up for a period of 12 months. Primary outcome is functional change measured over 12 months, using the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale. Secondary end points include measures of functional health, quality of life, calorie intake and weight, as well as time to gastrostomy and survival. A health economic analysis and process evaluation will also be undertaken. Participant recruitment is expected to complete in September 2025, and participant follow-up is expected to complete in September 2026. The results of this study are expected in March 2027.

ETHICS AND DISSEMINATION: The trial was approved by Greater Manchester-North West Research Ethics Committee, reference 20/NW/0334 on 8 September 2020. We will publish the study findings in peer-reviewed academic journals and present at local, national and international conferences where possible.

abstract = {Significant progress in high-throughput analytical techniques has paved the way for novel approaches to integrating data sets from different compartments. This study leverages nontarget screening (NTS) via liquid chromatography-high-resolution mass spectrometry (LC-HRMS), a crucial technique for analyzing organic micropollutants and their transformation products, in combination with biological indicators. We propose a combined multivariate data processing framework that integrates LC-HRMS-based NTS data with other high-throughput data sets, exemplified here by 18S V9 rRNA and full-length 16S rRNA gene metabarcoding data sets. The power of data fusion is demonstrated by systematically evaluating the impact of treated wastewater (TWW) over time on an aquatic ecosystem through a controlled mesocosm experiment. Highly compressed NTS data were compiled through the implementation of the region of interest-multivariate curve resolution-alternating least-squares (MCR-ALS) method, known as ROIMCR. By integrating ANOVA-simultaneous component analysis with structural learning and integrative decomposition (SLIDE), the innovative SLIDE-ASCA approach enables the decomposition of global and partial common, as well as distinct variation sources arising from experimental factors and their possible interactions. SLIDE-ASCA results indicate that temporal variability explains a much larger portion of the variance (74.6%) than the treatment effect, with both contributing to global shared space variation (41%). Design structure benefits include enhanced interpretability, improved detection of key features, and a more accurate representation of complex interactions between chemical and biological data. This approach offers a greater understanding of the natural and wastewater-influenced temporal patterns for each data source, as well as reveals associations between chemical and biological markers in an exemplified perturbed aquatic ecosystem.},

abstract = {SIGNIFICANCE: Excessive reactive oxygen species (ROS) in dysfunctional mitochondria, combined with inefficient antioxidant defenses, can drive amyotrophic lateral sclerosis (ALS) progression. L-methionine (Met) can neutralize ROS by modulating metabolism and activating antioxidants; however, its impact on ALS remains unknown.

AIM: We aim to investigate the influence of excess Met on cellular metabolism and ROS accumulation and its role in ALS using multimodal optical imaging techniques.

APPROACH: We applied deuterium oxide-probed stimulated Raman scattering imaging to study metabolic changes of lipids, proteins, and cytochrome c and two-photon excitation fluorescence imaging to assess mitochondrial redox state (nicotinamide adenine dinucleotide and flavin adenine dinucleotide ratio) in ALS cellular models under excess Met treatment. With three-dimensional (3D) image reconstruction, we investigated morphological changes of lipid droplets (LDs) and stress granules (SGs) in ALS models.

RESULTS: Excess Met not only promoted syntheses of lipids and unsaturated lipid membranes but also reduced protein synthesis, cytochrome c oxidation, and oxidative stress. Moreover, 3D image reconstruction showed that LDs increased in volume and number to promote cellular repair, whereas SGs decreased in volume but increased in number in response to reduced cellular stress.

CONCLUSIONS: Excess Met offers a protective mechanism against oxidative stress and promotes cellular repair in ALS.},

abstract = {BACKGROUND: Pathogenic variants of fused in sarcoma (FUS) cause amyotrophic lateral sclerosis (FUS-ALS), with evidence of gain of function. Jacifusen is an antisense oligonucleotide targeting FUS pre-mRNA, previously shown to delay neurodegeneration in a mouse model and potentially slow functional decline in a first-in-human study. Here, we sought to further evaluate use of jacifusen as a treatment for FUS-ALS.

METHODS: This expanded access programme was conducted through a series of single-patient investigational new drug applications at five sites (four hospitals in the USA and one in Switzerland). Participants carried a FUS variant and had clinical evidence of motor neuron disease onset or electrophysiological abnormalities, if not a diagnosis of ALS. Participants were ineligible if chronically ventilated with tracheostomy. Enrolled sequentially, participants received serial intrathecal injections of jacifusen over 2·8-33·9 months. Based on multiple ascending doses of jacifusen (from 20 mg to 120 mg), successive protocols were modified as safety and other data were acquired, with the last participants enrolled receiving 120 mg doses monthly from the start of their treatment. Safety was assessed using the Common Terminology Criteria for Adverse Events version 4.0 and standard cerebrospinal fluid (CSF) metrics. Concentration of neurofilament light chain (NfL) in CSF was used as a biomarker of axonal injury and neurodegeneration, and the ALS Functional Rating Scale-Revised (ALSFRS-R) score was used as an overall measure of motor function. Biochemical analysis and immunohistochemical staining were done on post-mortem CNS tissues to quantify FUS protein expression and assess the burden of FUS pathology.

FINDINGS: Between June 11, 2019, and June 2, 2023, we recruited 12 participants (median age 26 years [range 16-45]; seven [58%] were female and five [42%] were male) into the expanded access programme. Transient elevations in cell counts or total protein concentration in CSF (six [50%] participants) were unrelated to treatment duration. The most common adverse events were back pain (six [50%]), headache (four [33%]), nausea (three [25%]), and post-lumbar puncture headache (three [25%]). Two participant deaths were recorded during the programme, both thought to be unrelated to the investigational drug. The concentration of NfL in CSF was reduced by up to 82·8% after 6 months of treatment. Although most participants had continued functional decline (as measured by ALSFRS-R) after starting treatment with jacifusen, one showed unprecedented, objective functional recovery after 10 months, and another remained asymptomatic, with documented improvement in electromyographic abnormalities. Biochemical and immunohistochemical analysis of CNS tissue samples from four participants showed reduced FUS protein levels and an apparent decrease in the burden of FUS pathology.

INTERPRETATION: The findings suggest the safety and possible efficacy of jacifusen for treating FUS-ALS. The efficacy of jacifusen is being further evaluated in an ongoing clinical trial.

abstract = {OBJECTIVES: This study analyzed the acceptability of an electronic patient-reported outcomes measures-based model of care (IePRO MoC) and the usability of its complementary ePROM mobile app to monitor and manage symptoms related to immune checkpoint inhibitors. In this MoC, symptoms reported by patients treated at an outpatient clinic were reviewed by oncology triage nurses who provided symptom management interventions by telephone.

METHODS: As part of a larger intervention trial (ClinicalTrials.gov.NCT05530187) we conducted an abductive, semantic thematic analysis through semistructured interviews of patients participating in the intervention arm. Acceptability was deduced from Sekhon et al's (2017) Theoretical Framework of Acceptability completed with inductively generated themes. Usability analysis was guided by the mHealth App Usability Questionnaire's domains by Zhoul et al (2019).

RESULTS: A total of 17 interviews were performed. The IePRO MoC was reported to be an acceptable intervention. Patients expressed feeling safe and empowered due to continuous monitoring and timely support from nurses. Personalized support motivated patients to use the MoC throughout treatment. Some questioned the predefined response options of the app, and the standardized approach regarding notifications and monitoring requirements. Despite high app usability, some expressed discomfort from being frequently reminded of their illness and being confronted with questions about their sexuality and other intimate themes.

CONCLUSIONS: The feedback loop between patients and nurses facilitated the acceptability of the IePRO MoC. The app's usability further facilitated adherence to the MoC. A more personalized approach regarding the frequency of assessments and the way symptoms are conveyed is recommended to decrease discomfort and support the implementation of similar MoCs in the future.},

abstract = {BACKGROUND: Trehalose is a disaccharide that activates autophagy pathways in animal models of neurodegenerative diseases, with the potential to catalyse clearance of toxic, misfolded proteins in motor neurons and slow disease progression in amyotrophic lateral sclerosis (ALS). We aimed to evaluate the safety and efficacy of trehalose in individuals with ALS.

METHODS: The HEALEY ALS Platform Trial is a perpetual, adaptive, phase 2/3, randomised, double-blind, multi-regimen trial conducted at 60 geographically diverse sites in the USA. In the current regimen, adults with clinically possible, probable, laboratory-supported probable, or definite ALS, defined by the revised El Escorial criteria, were randomly allocated (3:1), stratified by use of edaravone and riluzole, to receive trehalose 0·75 g per kg intravenously weekly over 24 weeks, or matching placebo. The primary outcome was a composite of the relative rate of disease progression, as measured by the Revised ALS Functional Rating Scale (ALSFRS-R), and survival over 24 weeks, estimated in a Bayesian shared-parameter model. The study included prespecified stopping rules for futility; interim analyses occurred every 12 weeks. The primary outcome was analysed according to the intention-to-treat principle in all participants in the trehalose group, the placebo group within the regimen, and placebo groups from other contributing regimens; the safety analysis population was comprised of all participants who initiated treatment. This study is registered with ClinicalTrials.gov, NCT05136885.

FINDINGS: Between Feb 21, 2022, and Feb 17, 2023, 1021 participants were screened for the platform trial and 171 were assigned to the trehalose regimen. Of these, 161 participants met eligibility criteria, with 120 randomly allocated to trehalose and 41 to regimen-specific placebo. 164 participants randomly allocated to placebo in other regimens were added for analysis (totalling 205 placebo recipients). The disease rate ratio for change in ALSFRS-R and survival was 0·87 (95% credible interval 0·665-1·102, posterior probability of superiority 0·877). Serious adverse events occurred in 19 (16%) participants in the trehalose group and three (7%) participants in the regimen-only placebo group, leading to premature discontinuations in 14 (12%) versus one (2%), respectively. Fatal treatment-emergent adverse events occurred in seven participants in the trehalose group and none in the regimen-only placebo group. No death was considered related to the trial drug. The most common cause of death was respiratory failure, consistent with the natural history of ALS.

INTERPRETATION: Trehalose was well tolerated but there was no evidence to suggest a difference in ALS disease progression compared with placebo in this study. No statistical benefit was seen in secondary clinical or biomarker measures, suggesting that trehalose at this dosage is unlikely to be efficacious for treatment of ALS.

abstract = {Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that has no cure, and treatments predominantly focus on improving quality of life. Patient-centred care is central to bringing about meaningful improvements to quality of life. This review addresses the lack of consolidated evidence on what matters most to people with ALS (pwALS) by synthesizing 44 preference-based studies covering six different treatment and intervention categories. Data-based convergent synthesis identified five overarching factors influencing preferences: ease of use, accessibility, making life easier, autonomy, and safety/reliability. Simplifying and enhancing accessibility of treatment delivery across disease stages aligns with the nature of neurodegenerative disorders such as ALS, where function declines as the disease progresses. The value in perceived and real control reflects the profound impact ALS has on an individual's independence. Safety and reliability are crucial for people with ALS and are recognized as fundamental requirements for quality healthcare. The themes identified in this review can inform the attributes of preference elicitation methods. Systematically varying the levels of these attributes elicits quantitative measures of preferences. These findings can be used to inform and develop healthcare policy and clinical practice in ALS care. Specifically, preferences related to drug treatments can then be integrated into target product profiles (TPPs) to align drug development with the needs and values of pwALS. Integrating patient preferences into clinical practice promotes patient-centred care, increasing both patient satisfaction and treatment effectiveness.},

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

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

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

RESULTS: Thirteen predictive models and seven external validations were identified. Methodological issues were identified in all studies. Pooled estimates indicated that the KLIC (Kidney, Liver, Index surgery, Cemented prosthesis, C-reactive protein) score had fair discriminative performance (pooled c-statistic 0.62, 95% CI 0.55 to 0.69). Both the τ2 (0.02) and I2 (33.4) estimates indicated that between study heterogeneity was minimal. Meta-analysis indicated Shohat et al's model had good discriminative performance (pooled c-statistic 0.74, 95% CI 0.57 to 0.85). Both the τ2 (0.0) and I2 (0.0) indicated that between study heterogeneity was minimal.

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

abstract = {Neurodegenerative disorders (NDDs), including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and prion diseases, pose a significant and escalating health challenge in the context of an aging population. Gold nanoparticles (GNPs) have emerged as promising agents in the diagnostic and therapeutic realms of NDDs, due to their unique ability to enhance drug delivery across the blood-brain barrier (BBB). This paper presents a comprehensive review of the application of GNPs in the context of NDDs diagnosis and therapy, highlighting their potential to transform patient management. Additionally, we systematically address the critical challenges associated with the use of GNPs in the treatment and diagnosis of NDDs, focusing on pharmacokinetics and metabolism, toxicity, long-term biocompatibility, regulatory challenges, and cost-effectiveness. Furthermore, we synthesize ongoing clinical studies to provide a holistic perspective on the current state of research in this field. We also explore the prospective trajectories and clinical translational potential of GNPs, which may usher in a new era in the treatment of NDDs.},
