abstract = {BACKGROUND: Motor Neurone Disease (MND) leads to muscle weakening, affecting movement, speech, and breathing. Home mechanical ventilation, particularly non-invasive ventilation (NIV), is used to alleviate symptoms and support breathing in people living with MND. While home mechanical ventilation can alleviate symptoms and improve survival, it does not slow the progression of MND. This study addresses gaps in understanding end-of-life decision-making in those dependent on home mechanical ventilation, considering the perspectives of patients, family members, and bereaved families.

METHODS: A UK-wide qualitative study using flexible interviews to explore the experiences of people living with MND (n = 16), their family members (n = 10), and bereaved family members (n = 36) about the use of home mechanical ventilation at the end of life.

RESULTS: Some participants expressed a reluctance to discuss end-of-life decisions, often framed as a desire to "live for the day" due to the considerable uncertainty faced by those with MND. Participants who avoided end-of-life discussions often engaged in 'selective decision-making' related to personal planning, involving practical and emotional preparations. Many faced challenges in hypothesising about future decisions given the unpredictability of the disease, opting to make 'timely decisions' as and when needed. For those who became dependent on ventilation and did not want to discuss end of life, decisions were often 'defaulted' to others, especially once capacity was lost. 'Proactive decisions', including advance care planning and withdrawal of treatment, were found to empower some patients, providing a sense of control over the timing of their death. A significant proportion lacked a clear understanding of the dying process and available options.

CONCLUSIONS: The study highlights the complexity and evolution of decision-making, often influenced by the dynamic and uncertain nature of MND. The study emphasises the need for a nuanced understanding of decision-making in the context of MND.},

abstract = {Cystic echinococcosis is a zoonotic disease resulting from infection caused by the larval stage of Echinococcus granulosus. This study aimed to assess the specific proteins that are potential candidates for the development of a vaccine against E. granulosus. The data-independent acquisition approach was employed to identify differentially expressed proteins (DEPs) in E. granulosus samples. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was employed to identify several noteworthy proteins. Results: The DEPs in E. granulosus samples were identified (245 pericystic wall vs. parasite-free yellowish granuloma (PYG, 1725 PY vs. PYG, 2274 PN vs. PYG). Further examination of these distinct proteins revealed their predominant enrichment in metabolic pathways, amyotrophic lateral sclerosis, and neurodegeneration-associated pathways. Notably, among these DEPs, SH3BGRL, MST1, TAGLN2, FABP5, UBE2V2, and RARRES2 exhibited significantly higher expression levels in the PYG group compared with the PY group (P < 0.05). The findings may contribute to the understanding of the pathological mechanisms underlying echinococcosis, providing valuable insights into the development of more effective diagnostic tools, treatment modalities, and preventive strategies. SIGNIFICANCE: CE is a major public health hazard in the western regions of China, Central Asia, South America, the Mediterranean countries, and eastern Africa. Echinococcus granulosus is responsible for zoonotic disease through infection Our analysis focuses on the proteins in various samples by data-dependent acquisition (DIA) for proteomic analysis. The importance of this research is to develop new strategies and targets to protect against E. granulosus infections in humans.},

abstract = {Interleukin-33 (IL-33), belonging to the interleukin-1 cytokine family, has a decoy receptor soluble ST2 (sST2). IL-33 is found in oligodendrocytes and astrocytes and is involved in central nervous system healing and repair, whereas ST2 is found in microglia and astrocytes. Some studies have found a link between changes in the IL-33/ST2 pathway and neurodegenerative disorders. This review article investigates the relationship between the interleukin-33 (IL-33)/ST2 pathway and neurodegenerative disorders. It was discovered that soluble st2 levels were increased. Furthermore, IL-33 levels were found to be lower in many neurodegenerative diseases such as Alzheimer's and amyotrophic lateral sclerosis (ALS). The association with other disorders, such as ankylosing spondylitis, multiple sclerosis, and systemic lupus erythematosus (SLE), was also observed. Various studies suggest that ST2/IL-33 signalling may be pivotal in the disease modulation of neurodegenerative disorders. The serum sST2 level test can be useful in determining the inflammatory status and severity of illness in many neurodegenerative disorders. In this review, we will discuss recent findings concerning the interleukin-33 (IL-33)/ST2 pathway and its role in the diagnosis and treatment of diseases with neurodegeneration.},

abstract = {BACKGROUND: Amyotrophic lateral sclerosis (ALS) is characterized by loss of motor neurons due to degeneration of nerve cells within the brain and spinal cord. Early symptoms include limb weakness, twitching or muscle cramping, and slurred speech. As the disease progresses, difficulty breathing, swallowing, and paralysis can lead to death. Currently, there are no medications that cure ALS, and guidelines recommend treatments focused on symptom management. Intravenous (IV) edaravone was approved by the US Food and Drug Administration (FDA) in 2017 as a treatment to slow the progression of ALS. In May 2022, the FDA approved an oral suspension (ORS) formulation of edaravone.

MECHANISM OF ACTION: The mechanism of action of edaravone is not well defined. However, its neuroprotective effects are thought to result from antioxidant properties occurring through elimination of free radicals.

PHARMACOKINETICS: Edaravone ORS (105 mg) has a bioavailability of 57% when compared with edaravone IV (60 mg). The ORS should be taken on an empty stomach in the morning, with water and no food or beverages, for 1 hour. Edaravone is bound to albumin (92%), has a mean volume of distribution of 63.1 L, a half-life of 4.5-9 hours, and a total clearance of 35.9 L/h after intravenous administration. Edaravone is metabolized into nonactive sulfate and glucuronide conjugates.

CLINICAL TRIALS: The FDA approval was based on studies of the pharmacokinetics, safety, tolerability, and bioavailability of edaravone ORS. A phase III, global, multicenter, open-label safety study was conducted on edaravone ORS in 185 patients with ALS over 48 weeks. The most reported treatment-emergent adverse events were falls, muscular weakness, and constipation. Serious treatment-emergent adverse events included disease worsening, dysphagia, dyspnea, and respiratory failure.

THERAPEUTIC ADVANCE: Oral edaravone is an ALS treatment that can be self-administered or administered by a caregiver, precluding the need for administration by a health care professional in an institutional setting.},

abstract = {Weeds are the primary biotic constraint affecting sesame growth and production. Here, we applied EMS mutagenesis to an elite sesame cultivar and discovered a novel point mutation in the sesame SiALS gene conferring resistance to imidazolinone, a group of acetolactate-synthase (ALS)-inhibitors. The mutant line exhibited high resistance to imazamox, an ALS-inhibitor, with hybrid plants displaying an intermediate response. Field-based validation confirmed the mutant line's substantial resistance, leading to a significantly higher yield under imazamox treatment. Under pre-emergence application of imazapic, the mutant plants sustained growth, whereas wild-type and weed were effectively controlled. Field trials using s-metolachlor and imazapic combined resulted in weed-free plots compared to untreated controls. Consequently, this treatment showed a significantly greater yield (2280 vs. 880 Kg ha[-1]) than the commercial practice (s-metolachlor). Overall, our study unveils the potential of utilizing this point mutation in sesame breeding programs, offering new opportunities for integrated weed management strategies for sesame cultivation. Developing herbicide-resistant crop plants holds promise for supporting sustainable production and addressing the challenges of weed infestations in sesame farming.},

In such cases, weed control should be started in the spring. During this time, the plantation should be protected as effectively as possible because the weeds are at an advanced stage of growth. Therefore, they are less sensitive to applied herbicides. In the treatment, it is worth using a mixture of different mechanisms of action. Studies were conducted to evaluate the effectiveness of a band of tribenuron-methyl, and MCPA applied as soluble granules in spring control of dicotyledonous in winter cereals. The biological efficacy of herbicides was estimated in the 25 field experiments on winter cereals in Poland. Postemergence, a spring application of tribenuron-methyl + MCPA, effectively controls the majority of weed species present in spring: Anthemis arvensis, Brassica napus, Capsella bursa-pastoris, Centaurea cyanus, Lamium purpureum, Matricaria chamomilla, Tripleurospermum inodorum, Stellaria media and Thlaspi arvense. Satisfactory control was confirmed for Veronica persica, Viola arvensis, and Galium aparine. Tribenuron-methyl with MCPA is recommended for application to winter cereals in spring. To prevent the development of resistance in weeds, it is advantageous to combine two active substances.},

abstract = {BACKGROUND: Alzheimer's disease (AD) is the most prevalent neurodegenerative disease with limited disease-modifying treatments. Drug repositioning strategy has now emerged as a promising approach for anti-AD drug discovery. Using 5×FAD mice and Aβ-treated neurons in culture, we tested the efficacy of Y-2, a compounded drug containing the antioxidant Edaravone (Eda), a pyrazolone and (+)-Borneol, an anti-inflammatory diterpenoid from cinnamon, approved for use in amyotrophic lateral sclerosis patients.

RESULTS: We examined effects of Y-2 versus Eda alone by i.p. administered in 8-week-old 5×FAD mice (females) for 4 months by comparing cognitive function, Aβ pathologies, neuronal necroptosis and neuroinflammation. Using primary neurons and astrocytes, as well as neuronal and astrocytic cell lines, we elucidated the molecular mechanisms of Y-2 by examining neuronal injury, astrocyte-mediated inflammation and necroptosis. Here, we find that Y-2 improves cognitive function in AD mice. Histopathological data show that Y-2, better than Eda alone, markedly ameliorates Aβ pathologies including Aβ burden, astrogliosis/microgliosis, and Tau phosphorylation. In addition, Y-2 reduces Aβ-induced neuronal injury including neurite damage, mitochondrial impairment, reactive oxygen species production and NAD[+] depletion. Notably, Y-2 inhibits astrocyte-mediated neuroinflammation and attenuates TNF-α-triggered neuronal necroptosis in cell cultures and AD mice. RNA-seq further demonstrates that Y-2, compared to Eda, indeed upregulates anti-inflammation pathways in astrocytes.

CONCLUSIONS: Our findings infer that Y-2, better than Eda alone, mitigates AD pathology and may provide a potential drug candidate for AD treatment.},

abstract = {BACKGROUND/AIM: Glioblastoma multiforme (GBM)-induced oedema is a major cause of morbidity and mortality among patients with GBM. Dexamethasone (Dex) is the most common corticosteroid used pre-operatively to control cerebral oedema in patients with GBM. Dex is associated with many side effects, and shorter overall survival and progression-free survival of patients with GBM. These negative effects of Dex highlight the need for combinational therapy. Riluzole (Ril), a drug used to treat amyotrophic lateral sclerosis (ALS), is thought to have potential as a treatment for various cancers, with clinical trials underway. Here, we investigated whether Ril could reverse some of the undesirable effects of Dex.

MATERIALS AND METHODS: The effect of Dex, Ril, and Ril-Dex treatment on cell migration was monitored using the xCELLigence system. Cell viability assays were performed using 3-(4, 5-dimethylthiazol)-2, 5-diphenyltetrazolium bromide (MTT). The expression of genes involved in migration, glucose metabolism, and stemness was examined using real-time polymerase chain reaction (PCR).

RESULTS: Pre-treating GBM cells with Ril reduced Dex-induced cell migration and altered Dex-induced effects on cell invasion, stem cell, and glucose metabolism markers. Furthermore, Ril remained effective in killing GBM cells in combination with Dex.

CONCLUSION: Ril, which acts as an anti-tumorigenic drug, mediates some of the negative effects of Dex; therefore, it could be a potential drug to manage the side effects of Dex therapy in GBM.},

However, the clinical features of ALS among post-transplant pediatric patients have rarely been explored.

PROCEDURES: We retrospectively reviewed 2206 pediatric patients who had received an allo-HSCT between January 2013 and December 2019 at the Hebei Yanda Lu Daopei Hospital, and analyzed the role of ALS in prognosis following HSCT.

RESULTS: In our research, ALS was divided into two categories: 15 cases of bronchiolitis obliterans syndrome (BOS) and 13 cases of idiopathic pneumonia syndrome (IPS). Following treatment of the ALS, 18 patients survived (18/28, 64.3%), and 10 patients died of respiratory failure or infection (10/28, 35.7%).

CONCLUSIONS: The OS of ALS in Hebei Yanda Lu Daopei Hospital is significantly higher than others, and they were cited to be related to early diagnosis and timely FAM treatment in previous reports.},

abstract = {OBJECTIVE: L-carnitine (LC), a vital nutritional supplement, plays a crucial role in myocardial health and exhibits significant cardioprotective effects. LC, being the principal constituent of clinical-grade supplements, finds extensive application in the recovery and treatment of diverse cardiovascular and cerebrovascular disorders. However, controversies persist regarding the utilization of LC in nervous system diseases, with varying effects observed across numerous mental and neurological disorders. This article primarily aims to gather and analyze database information to comprehensively summarize the therapeutic potential of LC in patients suffering from nervous system diseases while providing valuable references for further research.

METHODS: A comprehensive search was conducted in PubMed, Web Of Science, Embase, Ovid Medline, Cochrane Library and Clinicaltrials.gov databases. The literature pertaining to the impact of LC supplementation on neurological or psychiatric disorders in patients was reviewed up until November 2023. No language or temporal restrictions were imposed on the search.

RESULTS: A total of 1479 articles were retrieved, and after the removal of duplicates through both automated and manual exclusion processes, 962 articles remained. Subsequently, a meticulous re-screening led to the identification of 60 relevant articles. Among these, there were 12 publications focusing on hepatic encephalopathy (HE), while neurodegenerative diseases (NDs) and peripheral nervous system diseases (PNSDs) were represented by 9 and 6 articles, respectively. Additionally, stroke was addressed in five publications, whereas Raynaud's syndrome (RS) and cognitive disorder (CD) each had three dedicated studies. Furthermore, migraine, depression, and amyotrophic lateral sclerosis (ALS) each accounted for two publications. Lastly, one article was found for other symptoms under investigation.

CONCLUSION: In summary, LC has demonstrated favorable therapeutic effects in the management of HE, Alzheimer's disease (AD), carpal tunnel syndrome (CTS), CD, migraine, neurofibromatosis (NF), PNSDs, RS, and stroke. However, its efficacy appears to be relatively limited in conditions such as ALS, ataxia, attention deficit hyperactivity disorder (ADHD), depression, chronic fatigue syndrome (CFS), Down syndrome (DS), and sciatica.},

Measures derived directly from a nerve excitability recording are frequently used as study endpoints, even though their biophysical basis is difficult to deduce. Mathematical models can aid in the interpretation, but are only reliable when applied to group-averaged recordings. Consequently, model estimates of membrane properties cannot be compared to clinical characteristics or treatment effects in individual patients, posing a considerable limitation in heterogeneous diseases such as amyotrophic lateral sclerosis. To address these challenges, we revisited nerve excitability using a novel pattern-analysis-based approach (principal component analysis). We evaluated disease-specific patterns of excitability changes and established their biophysical origins. Based on the observed patterns, we developed novel compound measures of excitability that facilitate the implementation of this approach in clinical settings We found that excitability changes in amyotrophic lateral sclerosis patients (n = 161, median disease duration = 11 months) were characterized by four unique patterns compared to controls (n = 50, age-gender matched). These four patterns were best explained by changes in resting membrane potential (modulated by Na+/K + -currents), slow potassium- and sodium-currents (modulated by their gating kinetics) and refractory properties of the nerve. Consequently, we were able to show that altered gating of slow potassium-channels was associated with, and predictive of, the disease's progression rate on the amyotrophic lateral sclerosis functional rating scale. Based on these findings, we designed four composite measures that capture these properties to facilitate implementation outside of this study. Our findings demonstrate that nerve excitability changes in patients with amyotrophic lateral sclerosis are dominated by four distinct patterns, each with a distinct biophysical origin. Based on this new approach, we provide evidence that altered slow potassium-channel function may play a role in the rate of disease progression. The magnitudes of these patterns, quantified using either a similar approach or our novel composite measures, have potential as efficient measures to study membrane properties directly in amyotrophic lateral sclerosis patients, and thus aid prognostic stratification and trial design.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neuromuscular disorder characterized by progressive weakness of almost all skeletal muscles, whereas extraocular muscles (EOMs) are comparatively spared. While hindlimb and diaphragm muscles of end-stage SOD1G93A (G93A) mice (a familial ALS mouse model) exhibit severe denervation and depletion of Pax7[+]satellite cells (SCs), we found that the pool of SCs and the integrity of neuromuscular junctions (NMJs) are maintained in EOMs. In cell sorting profiles, SCs derived from hindlimb and diaphragm muscles of G93A mice exhibit denervation-related activation, whereas SCs from EOMs of G93A mice display spontaneous (non-denervation-related) activation, similar to SCs from wild-type mice. Specifically, cultured EOM SCs contain more abundant transcripts of axon guidance molecules, including Cxcl12, along with more sustainable renewability than the diaphragm and hindlimb counterparts under differentiation pressure. In neuromuscular co-culture assays, AAV-delivery of Cxcl12 to G93A-hindlimb SC-derived myotubes enhances motor neuron axon extension and innervation, recapitulating the innervation capacity of EOM SC-derived myotubes. G93A mice fed with sodium butyrate (NaBu) supplementation exhibited less NMJ loss in hindlimb and diaphragm muscles. Additionally, SCs derived from G93A hindlimb and diaphragm muscles displayed elevated expression of Cxcl12 and improved renewability following NaBu treatment in vitro. Thus, the NaBu-induced transcriptomic changes resembling the patterns of EOM SCs may contribute to the beneficial effects observed in G93A mice. More broadly, the distinct transcriptomic profile of EOM SCs may offer novel therapeutic targets to slow progressive neuromuscular functional decay in ALS and provide possible 'response biomarkers' in pre-clinical and clinical studies.},

Vitamin B12 is not a Food and Drug Administration-approved treatment in the United States, although it has been prescribed off-label as ultra-high-dose methylcobalamin, which has been shown to be safe and effective in slowing functional decline in patients with ALS. This study evaluates the impact of Vitamin B12 injections on the quality of life of five patients.

METHODS: Semi-structured interviews were conducted with the patients and caregivers. The data was carefully read, coded, and organized into themes and sub-themes by two independent researchers.

RESULTS: The study found four themes and 11 subthemes from the data, including initial circumstances, administration of the injection, subjective experience with Vitamin B12, and outcomes and expectations. All participants recognized some benefits from Vitamin B12 injections, specifically increased energy, reduced fatigue, and improved balance. However, some patients had difficulty monitoring its specific effect due to the progressive nature of the disease.

DISCUSSION: The flexibility offered by this intervention is beneficial for patients with declining mobility and strength who wish to adapt their treatment to their schedule. This work is a modest call to fill the existing gap in the literature and push for more randomized controlled trials investigating and clarifying the effects of Vitamin B12 injections on disease progression, muscle function, and quality of life in a small but diverse pool of patients with ALS.},

abstract = {Cover crops, a soil conservation practice, can contribute to reducing disease pressure caused by Pseudomonas syringae, considered one of the most important bacterial plant pathogens. We recently demonstrated that phyllosphere (leaf surface) bacterial community structure changed when squash (Cucurbita pepo) was grown with a rye (Secale cereale) cover crop treatment, followed by a decrease of angular leaf spot (ALS) disease symptoms on squash caused by P. syringae pv. lachrymans. Application of biocontrol agents is a known agricultural practice to mitigate crop losses due to microbial disease. In this study, we tested the hypothesis that some phyllosphere bacteria promoted when squash are grown on cover crops could be isolated and used as a biocontrol agent to decrease ALS symptoms. We grew squash during a two-year field experiment using four agricultural practices: bare soil, cover crops, chemically terminated cover crops, and plastic cover. We sampled squash leaves at 3 different dates each year and constructed a collection of cultivable bacterial strains isolated from squash leaves and rye cover crop material. Each isolated strain was identified by 16S rRNA gene sequencing and used in in vitro (Petri dish) pathogen growth and in vivo (greenhouse) symptom control assays. Four bacterial isolates belonging to the genera Pseudarthrobacter, Pseudomonas, Delftia and Rhizobium were shown to inhibit P. syringae pv. lachrymans growth and ALS symptom development. Strikingly, the symptom control efficacy of all strains was stronger on older leaves. This study sheds light on the importance of bacterial isolation from cover crops sources to promote disease control.},

After synthesis and characterization of the mentioned cinnolines (3a-h), the in silico multi-targeting inhibitory properties of these heterocyclic scaffolds have been investigated upon various Homo sapiens-type enzymes, including hMAO-A, hMAO-B, hAChE, hBChE, hBACE-1, hBACE-2, hNQO-1, hNQO-2, hnNOS, hiNOS, hPARP-1, hPARP-2, hLRRK-2[(G2019S)], hGSK-3β, hp38α MAPK, hJNK-3, hOGA, hNMDA receptor, hnSMase-2, hIDO-1, hCOMT, hLIMK-1, hLIMK-2, hRIPK-1, hUCH-L1, hPARK-7, and hDHODH, which have confirmed their functions and roles in the neurodegenerative diseases (NDs), based on molecular docking studies, and the obtained results were compared with a wide range of approved drugs and well-known (with IC50, EC50, etc.) compounds. In addition, in silico ADMET prediction analysis was performed to examine the prospective drug properties of the synthesized heterocyclic compounds (3a-h). The obtained results from the molecular docking studies and ADMET-related data demonstrated that these series of 3-aryl(or heteroaryl)-5,6-dihydrobenzo[h]cinnolines (3a-h), especially hit ones, can really be turned into the potent core of new drugs for the treatment of neurodegenerative diseases (NDs), and/or due to the having some reactionable locations, they are able to have further organic reactions (such as cross-coupling reactions), and expansion of these compounds (for example, with using other types of aryl(or heteroaryl)glyoxal monohydrates) makes a new avenue for designing novel and efficient drugs for this purpose.},

Data from one randomized clinical trial suggests minimal delays in disease progression and longer survivability, but debate remains about the lack of confirmatory evidence of effectiveness owing to study limitations. A patient's decision-making process details the experience of using the drug, including perspectives on access, cost, effectiveness, and adverse effects.

Early marketing approval, despite community demands, is unnecessary and may have reduced access because of the end of a compassionate use program, and the high price tag results in restricted coverage and high out-of-pocket costs.

abstract = {BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative disorder distinguished by a swift cognitive deterioration accompanied by distinctive pathological hallmarks such as extracellular Aβ (β-amyloid) peptides, neuronal neurofibrillary tangles (NFTs), sustained neuroinflammation, and synaptic degeneration. The elevated frequency of AD cases and its proclivity to manifest at a younger age present a pressing challenge in the quest for novel therapeutic interventions. Numerous investigations have substantiated the involvement of C/EBPβ in the progression of AD pathology, thus indicating its potential as a therapeutic target for AD treatment.

AIMS: Several studies have demonstrated an elevation in the expression level of C/EBPβ among individuals afflicted with AD. Consequently, this review predominantly delves into the association between C/EBPβ expression and the pathological progression of Alzheimer's disease, elucidating its underlying molecular mechanism, and pointing out the possibility that C/EBPβ can be a new therapeutic target for AD.

METHODS: A systematic literature search was performed across multiple databases, including PubMed, Google Scholar, and so on, utilizing predetermined keywords and MeSH terms, without temporal constraints. The inclusion criteria encompassed diverse study designs, such as experimental, case-control, and cohort studies, restricted to publications in the English language, while conference abstracts and unpublished sources were excluded.

RESULTS: Overexpression of C/EBPβ exacerbates the pathological features of AD, primarily by promoting neuroinflammation and mediating the transcriptional regulation of key molecular pathways, including δ-secretase, apolipoprotein E4 (APOE4), acidic leucine-rich nuclear phosphoprotein-32A (ANP32A), transient receptor potential channel 1 (TRPC1), and Forkhead BoxO (FOXO).

DISCUSSION: The correlation between overexpression of C/EBPβ and the pathological development of AD, along with its molecular mechanisms, is evident. Investigating the pathways through which C/EBPβ regulates the development of AD reveals numerous multiple vicious cycle pathways exacerbating the pathological progression of the disease. Furthermore, the exacerbation of pathological progression due to C/EBPβ overexpression and its molecular mechanism is not limited to AD but also extends to other neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), and multiple sclerosis (MS).

CONCLUSION: The overexpression of C/EBPβ accelerates the irreversible progression of AD pathophysiology. Additionally, C/EBPβ plays a crucial role in mediating multiple pathways linked to AD pathology, some of which engender vicious cycles, leading to the establishment of feedback mechanisms. To sum up, targeting C/EBPβ could hold promise as a therapeutic strategy not only for AD but also for other degenerative diseases.},

abstract = {BACKGROUND AND OBJECTIVE: Acupuncture combined with traditional Chinese medicine fumigation is increasingly being used in treating sequelae of pelvic inflammatory disease (SPID). However, there is a lack of meta-analysis on the effectiveness of acupuncture combined with traditional Chinese medicine fumigation in treating SPID. The aim of this study was to assess the feasibility of combining acupuncture with traditional Chinese medicine fumigation in the treatment of SPID.

METHODS: We searched eight databases for studies on acupuncture combined with traditional Chinese medicine fumigation for the treatment of SPID from the date of establishment to October 29, 2022. We assessed the quality of included studies by using the Cochrane bias risk tool. Pooled results were expressed as risk ratios (RRs), with a 95% confidence interval (CI). In addition, we identified sources of heterogeneity by sensitivity analysis, assessed publication bias by Egger's test, and assessed the quality of the evidence by Grades of Recommendation, Assessment, Development, and Evaluation (GRADE). All statistical analyses were performed by Review Manager 5.3 and Stata 14.

RESULTS: Finally, seven studies with a total of 663 participants were included. We found a significant difference in the total effective rate in the acupuncture combined with the fumigation group compared with the acupuncture group in the treatment of SPID (RR = 1.17, 95% CI [1.09, 1.25], p = 0.0001 < 0.05; I2 = 0%; 6 trials), and a significant difference in the total effective rate in the acupuncture combined with fumigation group compared with the fumigation group in the treatment of SPID (RR = 1.42, 95% CI [1.21, 1.66], p = 0.0001 < 0.05; 5 trials).

CONCLUSION: The clinical efficacy of acupuncture combined with herbal fumigation in the treatment of SPID is relatively good. Larger scale studies are needed in the future.

Das Ziel dieser Studie ist die Beurteilung der Machbarkeit der Kombination aus Akupunktur und Fumigation gemäß der Traditionellen Chinesischen Medizin in der Behandlung von SPID.Wir durchsuchten acht Datenbanken nach Studien zur Akupunktur in Kombination mit Fumigation gemäß der Traditionellen Chinesischen Medizin in der Behandlung von Folgeerscheinungen von SPID von der Einrichtung bis zum 29. Oktober 2022. Wir beurteilten die Qualität der eingeschlossenen Studien mit dem Cochrane-Tool zur Bewertung des Bias-Risikos. Die gepoolten Ergebnisse wurden als Risikoquotient (RR; risk ratio) mit 95%-Konfidenzintervall (KI) ausgedrückt. Zusätzlich identifizierten wir Quellen für Heterogenität mittels Sensitivitätsanalyse, beurteilten den Publikations-Bias mittels Egger-Test und bewerteten die Qualität der Evidenz nach Grad der Empfehlungsstärke, Beurteilung, Entwicklung und Evaluierung (GRADE). Alle statistischen Analysen erfolgten mit Review Manager 5.3 und Stata 14.Im Endeffekt wurden 7 Studien mit insgesamt 663 Teilnehmern eingeschlossen. Wir fanden einen signifikanten Unterschied in der Gesamt-Effektivitätsrate bei der Gruppe, die zur Behandlung von SPID Akupunktur in Kombination mit Fumigation erhielt, im Vergleich zur reinen Akupunkturgruppe (RR = 1,17; 95%-KI [1,09; 1,25]; p = 0,0001 < 0,05; I2-Wert = 0%; 6 Studien), und einen signifikanten Unterschied in der Gesamt-Effektivitätsrate bei der Gruppe, die zur Behandlung von SPID Akupunktur in Kombination mit Fumigation erhielt, im Vergleich zur reinen Fumigationsgruppe (RR = 1,42; 95%-KI [1,21; 1,66]; p = 0,0001 < 0,05; 5 Studien).Die klinische Wirksamkeit der Akupunktur in Kombination mit Kräuter-Fumigation zur Behandlung von SPID ist relativ gut.

abstract = {INTRODUCTION: Dry eye disorder (DED) is a growing global issue linked to excessive digital screen time. Chinese eye exercise of acupoint (CEA), a set of self-massages on shared Chinese acupuncture (CA), has been used to reduce visual-related ocular symptoms and possibly as an alternative treatment for DED. This study aimed to assess the efficacy and safety of CEA.

METHODS: A single-blind randomized controlled trial was conducted at Thammasat University Hospital in Thailand, recruiting 56 participants aged 20-60 years, equally divided into two groups: the treatment group with CEA and the control group with standard lid hygiene treatment (STD). The intervention program lasted 12 weeks.

MAIN OUTCOME MEASURES: Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), Schirmer-I test (SIT), corneal surface staining (CSS), and self-recorded forms for safety and adverse effects were measured at baseline, week 4, and week 12. An independent sample t test, paired t test, and repeated measures (ANOVA) were used to compare results between both groups, study visits, and primary and secondary outcome measurements, respectively. The p values <0.05 were considered statistically significant.

RESULTS: The characteristics were not statistically different between both groups at the baseline. The mean OSDI scores were significantly reduced in both groups at week 4 and week 12 compared to baseline (p value <0.05). Additionally, both CEA and STD showed significant improvement in TBUT and SIT (p value <0.05). CSS was significantly improved only in the CEA groups (p value <0.05). No significant differences were observed between the study groups, except for SIT at week 12 (p value <0.05). For the safety, there were no adverse side effects in either group.

CONCLUSION: CEA seemed to be as effective as STD in improving the OSDI, TBUT, and SIT of DED without causing any side effects.

UNLABELLED: Das Trockene Auge (Dry eye disorder, DED) ist weltweit ein zunehmendes Problem, das mit übermässiger Bildschirmarbeit zusammenhängt. Die chinesische Augenübung der Akupunkturpunkte (Chinese eye exercise of acupoint, CEA), eine Reihe von Selbstmassagen an gemeinsamen CA-Akupunkturpunkten, wird zur Linderung visusbezogener Augensymptome und als mögliche alternative Behandlung für DED eingesetzt. Mit dieser Studie sollte die Wirksamkeit und Sicherheit von CEA bewertet werden.Am Thammasat-Universitätsklinikum in Thailand wurde eine einfach verblindete, randomisierte, kontrollierte Studie mit 56 Teilnehmern im Alter von 20 bis 60 Jahren durchgeführt, die zu gleichen Teilen zwei Gruppen zugewiesen wurden: die Behandlungsgruppe mit CEA und die Kontrollgruppe, die die Standard-Lidhygienebehandlung erhielt (STD). Das Interventionsprogramm dauerte 12 Wochen. Die Haupt-Zielkriterien, der Ocular Surface Disease Index (OSDI), die Tränenfilmaufreisszeit (tear break-up time, TBUT), der Schirmer-I-Test (SIT), das Corneal Surface Staining (CSS) und Selbstauskunftsformulare zur Sicherheit und zu unerwünschten Wirkungen wurden zu Beginn der Behandlung, in Woche 4 und in Woche 12 ermittelt. Für den Vergleich der Ergebnisse zwischen den beiden Gruppen, den Studienvisiten bzw. den primären und sekundären Zielkriterien wurden ein t Test für unabhängige Stichproben, ein t Test für paarige Stichproben und eine ANOVA mit Messwiederholungen verwendet. p-Werte <0,05 galten als statistisch signifikant.Hinsichtlich der Merkmale bestand zwischen den beiden Gruppen kein statistischer Unterschied bei Studienbeginn. In beiden Gruppen fielen die mittleren OSDI-Scores in Woche 4 und Woche 12 im Vergleich zum Ausgangswert signifikant geringer aus (p-Wert <0,05). Darüber hinaus zeigten sowohl die CEA- als auch die STD-Gruppe eine signifikante Verbesserung der TBUT- und SIT-Werte (p-Wert <0,05). Das CSS verbesserte sich nur in der CEA-Gruppe signifikant (p-Wert <0,05). Zwischen den Studiengruppen waren keine signifikanten Unterschiede zu beobachten, ausser beim SIT in Woche 12 (p-Wert <0,05). Was die Sicherheit betrifft, so traten in beiden Gruppen keine unerwünschten Nebenwirkungen auf.Die CEA schien die OSDI-, TBUT- und SIT-Werte bei DED ebenso wirksam zu verbessern wie die Standardbehandlung, ohne Nebenwirkungen zu verursachen.},

abstract = {INTRODUCTION: Homeopathic medicines have been used for decades in the prevention and treatment of infectious diseases. However, the preventive efficacy of specific homeopathic medicines in COVID-19 is not well characterized. This study aimed to evaluate the comparative efficacy of prespecified homeopathic medicines in preventing COVID-19.

METHODS: A community-based, double-blind, randomized, placebo-controlled trial was conducted on 4,034 participants residing in Ward No. 27 of the Howrah Municipal Corporation in India. Participants were randomized to receive one of three prespecified homeopathic medicines [Influenzinum 30C, Arsenicum album 30C, Anas barbariae hepatis et cordis extractum 200K (Oscillococcinum®)], or placebo. The outcomes were the incidence of laboratory-confirmed and suspected cases of COVID-19 during a follow-up period of 1 month.

RESULTS: During the follow-up period, a total of 13 new laboratory-confirmed COVID-19 cases were reported in the study population. Among these, 5 cases in Influenzinum group, 2 cases in Arsenicum album group, 1 case in Oscillococcinum® group, and 5 cases in Placebo group were reported. On the other hand, number of suspected COVID-19 cases was significantly less in all the three homeopathic medicine groups compared to placebo. The least number of suspected cases reported in the Oscillococcinum® group (aOR: 0.058; 95% confidence interval [CI]: 0.029, 0.114), followed by the Arsenicum album (aOR: 0.337; 95% CI: 0.238, 0.475) and Influenzinum (aOR: 0.539; 95% CI: 0.401, 0.726) groups.

CONCLUSION: Prespecified homeopathic medicines, particularly Oscillococcinum® and Arsenicum album 30C, may have a role in preventing COVID-19, especially in reducing the incidence of suspected or COVID-19-like respiratory illnesses. However, the result failed to demonstrate a statistically significant difference in the occurrence of confirmed cases of COVID-19 between the study groups. Further research is needed to evaluate the efficacy of these medicines in different populations and settings.

UNLABELLED: Homöopathische Arzneimittel werden seit Jahrzehnten zur Prävention und Behandlung von Infektionskrankheiten eingesetzt. Die Wirksamkeit spezifischer homöopathischer Arzneimittel zur Prophylaxe von COVID-19 ist jedoch nicht gut untersucht. Mit dieser Studie sollte die vergleichende Wirksamkeit spezifischer homöopathischer Arzneimittel bei der Prävention von COVID-19 untersucht werden.Es handelte sich um eine gemeindebasierte, doppelblinde, randomisierte, placebokontrollierte Studie mit 4.034 Teilnehmern, die im Bezirk Nr. 27 der Howrah Municipal Corporation in Indien lebten. Die Teilnehmer erhielten randomisiert eines von drei zuvor festgelegten homöopathischen Arzneimitteln [Influenzinum 30C, Arsenicum album 30C, Anas barbariae hepatis et cordis extractum 200K (Oscillococcinum®)] oder Placebo. Zielkriterien waren die Inzidenz von laborchemisch bestätigten und vermuteten COVID-19-Fällen während des Follow-up-Zeitraums von einem Monat.Während des Follow-up-Zeitraums wurden insgesamt 13 neue, laborchemisch bestätigte COVID-19-Fälle in der Studienpopulation berichtet, davon 5 Fälle in der Influenzinum-Gruppe, 2 Fälle in der Arsenicum album-Gruppe, 1 Fall in der Oscillococcinum®-Gruppe und 5 Fälle in der Placebo-Gruppe. Demgegenüber fiel Zahl der COVID-19-Verdachtsfälle in allen drei homöopathischen Arzneimittelgruppen signifikant geringer aus als in der Placebogruppe.

Allerdings war kein statistisch signifikanter Unterschied im Auftreten von bestätigten COVID-19-Fällen zwischen den Studiengruppen nachweisbar. Weitere Untersuchungen sind erforderlich, um die Wirksamkeit dieser Arzneimittel in verschiedenen Populationen und Umgebungen zu bewerten.},

abstract = {OBJECTIVE: Type 2 diabetes mellitus (T2DM) is a prevalent metabolic disorder, and there is an increasing interest in the potential benefits of traditional Chinese medicine, such as Huanglian Jiedu decoction (HJD), for its management. This meta-analysis aimed to determine the efficacy and safety of HJD in the treatment of T2DM.

METHODS: A systematic review was conducted across six databases including PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang, from their inception to August 24, 2023. We focused on randomized controlled trials (RCTs) that evaluated HJD as both a monotherapy and in combination treatments for T2DM patients. Data analysis was performed using RevMan 5.3 and Stata 17.0, with evaluations for heterogeneity and publication bias. Additionally, subgroup analyses were stratified based on the duration of treatment.

RESULTS: A total of 40 studies involving 3,934 participants were included in the meta-analysis. Both HJD monotherapy and combined with other therapies significantly reduced hemoglobin A1C (HbA1c) fasting blood glucose (FBG) and 2-h postprandial glucose (2hPG) levels, as well as improved insulin resistance. Furthermore, combination therapy enhanced the efficacy rate and favorably altered lipid profiles, including increasing HDL-C and decreasing LDL-C, TC, and TG levels. It was worth noting that the results of the subgroup analysis indicated that, in terms of reducing HbA1c and 2hPG, the efficacy of HJD alone for a duration of less than 3 months was found to be potentially superior to that observed in treatments exceeding 3 months. Adverse event assessment suggested that HJD did not increase the incidence of side effects, including diarrhea, affirming its safety.

CONCLUSION: HJD appears to be an effective and safe alternative or adjunctive therapy for T2DM, showing significant improvements in glycemic control and lipid profiles without increasing adverse events. Further rigorous, multicenter RCTs outside China are warranted to validate these findings.

UNLABELLED: Diabetes mellitus Typ 2 (DMT2) ist eine weit verbreitete Stoffwechselerkrankung, und es besteht ein steigendes Interesse an den potenziellen Vorteilen der traditionellen chinesischen Medizin, wie beispielsweise Huanglian Jiedu-Dekokt (HJD), zu seiner Behandlung. Mit dieser Metaanalyse sollten die Wirksamkeit und Sicherheit von HJD zur Behandlung von DMT2 ermittelt werden.Es wurde eine systematische Recherche in sechs Datenbanken durchgeführt, darunter PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure (CNKI) und Wanfang, für die Zeit vom Beginn der Datenbank bis zum 24. August 2023. Dabei lag unser Hauptaugenmerk auf randomisierten kontrollierten Studien (RCTs), die HJD sowohl als Monotherapie als auch in Kombinationstherapien bei Patienten mit DMT2 untersuchten. Die Datenanalyse erfolgte mithilfe von RevMan 5.3 und Stata 17.0 mit Untersuchungen auf Heterogenität und Publikationsverzerrungen. Darüber hinaus wurden Subgruppenanalysen stratifiziert nach Behandlungsdauer durchgeführt.Insgesamt wurden 40 Studien mit 3.934 Teilnehmern in die Metaanalyse eingeschlossen. HJD führte sowohl als Monotherapie als auch in Kombination mit anderen Therapien zu einer signifikanten Senkung des HbA1c-Nüchternblutzuckerspiegels (fasting blood glucose, FBG) und der postprandialen Blutzuckerwerte 2 Stunden nach dem Essen (2-h postprandial glucose, 2hPG) sowie zu einer Verbesserung der Insulinresistenz. Darüber hinaus verbesserte die Kombinationstherapie die Wirksamkeitsrate und führte zu einer positiven Veränderung der Lipidprofile, die eine Erhöhung der HDL-Cholesterinwerte und eine Senkung der LDL-, Gesamtcholesterin- und Trigylceridwerte einschloss. Erwähnenswert ist, dass nach den Ergebnissen der Subgruppenanalyse die Wirksamkeit von HJD als Monotherapie in Hinblick auf die Senkung der HbA1c- und 2hPG-Werte bei einer Behandlungsdauer von weniger als drei Monaten gegenüber derjenigen von Behandlungen, die länger als drei Monate dauerten, potenziell überlegen war. Die Bewertung der unerwünschten Ereignisse zeigte, dass HJD nicht zu einem Anstieg der Nebenwirkungen wie Durchfall führte, was seine Sicherheit bestätigte.HJD scheint eine wirksame und sichere Alternative oder Zusatztherapie bei DMT2 zu sein, die signifikante Verbesserungen der Blutzuckerkontrolle und der Lipidprofile ohne Zunahme der unerwünschten Ereignisse bewirkt. Weitere rigorose, multizentrische RCTs außerhalb Chinas sind erforderlich, um diese Ergebnisse zu validieren.},

abstract = {BACKGROUND: Bryophyllum preparations are widely used in anthroposophic medicine, most often for mental and behavioural disorders. Three prospective studies have revealed positive effects of Bryophyllum pinnatum on sleep quality, and various trials have shown very good tolerability. Results from animal models have indicated CNS depressant and anxiolytic effects. This survey was conducted at the hospital "Klinik Arlesheim" in Switzerland to find out how the physicians and the nursing staff perceive the effectiveness and the tolerability of the Bryophyllum preparations they most frequently use.

DESIGN: Internal, anonymous online survey of healthcare professionals (April 8-May 31, 2022). The questionnaire comprised 105 multiple-choice questions. Answering the questions was taken as consent to participate in the survey.

PARTICIPANTS AND METHODS: All physicians and nursing staff with a valid email address at the hospital "Klinik Arlesheim AG" were invited via email to participate in this REDCap survey. The data were analysed descriptively.

RESULTS: Out of 266 invited participants, 48 answered some and 36 answered all questions (response rate between 18.0% and 13.5%). The participants had long experience with Bryophyllum preparations and were comprised approximately equal numbers of physicians and nursing staff. Various Bryophyllum preparations from the hospital's own production and Wala Heilmittel GmbH (in both cases produced from the species B. daigremontianum) and from Weleda AG (species B. pinnatum) were used. The indications for which most participants had prescribed or administered Bryophyllum preparations "very frequently" were anxiety, sleep disorders, crisis situations in oncology, posttraumatic stress disorder, benzodiazepine dependence/withdrawal, and depression. Improvements such as relief from restlessness, decreased anxiety, balance, easier falling asleep, better sleeping through, increased resilience, mood elevation, and less urge to move one's legs were reported "frequently" or "very frequently." Almost all participants agreed that Bryophyllum can be used to reduce the intake of synthetic sedatives or psychotropic drugs, but only approximately half believed that it could replace them. The majority of participants mentioned good tolerability of the various products, but a few reported occasional stomach or intestinal irritation, daytime fatigue, drowsiness, diarrhoea, and nausea.

CONCLUSION: Bryophyllum preparations are perceived as helpful in the treatment of various mental disorders, particularly anxiety, and are generally well tolerated. Most of these preparations are used for indications that have not yet been clinically investigated.

UNLABELLED: Bryophyllum-Präparate werden in der Anthroposophischen Medizin sehr häufig zur Behandlung von psychischen und Verhaltensstörungen eingesetzt. Drei prospektive Studien zeigten zudem positive Wirkungen von Bryophyllum pinnatum (BP) auf die Schlafqualität. Auch die Verträglichkeit wurde in allen bisherigen Studien als sehr gut bewertet. In Tiermodellen wurden ZNS-depressive und anxiolytische Effekte von BP festgestellt. Die hier durchgeführte Umfrage fand an der Klinik Arlesheim (Schweiz) statt. Sie diente dazu herauszufinden, wie Ärztinnen und Ärzte sowie das Pflegepersonal die Wirksamkeit und Verträglichkeit der von ihnen am häufigsten verwendeten Bryophyllum-Präparate wahrnehmen.Interne, anonyme, Online-Befragung unter ärztlichen und pflegerischen Fachkräften (8. April–31. Mai 2022). Der Fragebogen umfasste 105 Multiple-Choice-Fragen. Die Beantwortung der Fragen wurde als Zustimmung zur Teilnahme an der Umfrage interpretiert.Alle Ärztinnen, Ärzte und Pflegefachpersonen mit einer gültigen E-Mail-Adresse der “Klinik Arlesheim AG” wurden per E-Mail eingeladen, an dieser REDCap-Umfrage teilzunehmen. Die Daten wurden deskriptiv ausgewertet.Von den 266 eingeladenen Teilnehmenden beantworteten 48 einige und 36 alle Fragen (Antwortquote zwischen 18.0% und 13.5%). Die Teilnehmenden hatten langjährige Erfahrung mit Bryophyllum-Präparaten und setzten sich etwa zu gleichen Teilen aus ärztlichen und pflegerischen Fachkräften zusammen. Die Resultate zeigen, dass verschiedenste Bryophyllum-Präparate aus klinikeigener Herstellung, von der Wala Heilmittel GmbH (Art B. daigremontianum) und von der Weleda AG (Art B. pinnatum) verwendet werden. Zu den Indikationen, bei denen die meisten Teilnehmenden Bryophyllum-Präparate “sehr häufig” verordnet oder angewendet haben, gehören Angstzustände, Schlafstörungen, Krisensituationen in der Onkologie, Posttraumatische Belastungsstörung, Benzodiazepin-Abhängigkeit/Entzug und Depressionen. Gesundheitsverbesserungen wie Linderung von Unruhe, verminderte Angst, Ausgeglichenheit, leichteres Einschlafen, besseres Durchschlafen, erhöhte Belastbarkeit, Stimmungsaufhellung und weniger Drang, die Beine zu bewegen, wurden als “häufig” oder “sehr häufig” angegeben. Fast alle Teilnehmenden waren sich einig, dass Bryophyllum verwendet werden kann, um die Einnahme von synthetischen Beruhigungsmitteln oder Psychopharmaka zu reduzieren, aber nur etwa die Hälfte gab an, dass es diese ersetzen kann. Die Mehrheit der Teilnehmenden spricht von einer guten Verträglichkeit der verschiedenen Produkte. Einige wenige berichteten von gelegentlicher Magen- oder Darmreizung, Tagesmüdigkeit, Schläfrigkeit, Durchfall und Übelkeit.Bryophyllum-Präparate werden als hilfreich bei der Behandlung verschiedener psychischen Störungen, insbesondere bei Angstzuständen, angesehen und im Allgemeinen gut vertragen. Die meisten der angegebenen Präparate werden für Indikationen verwendet, die noch nicht klinisch untersucht worden sind.},

abstract = {INTRODUCTION: Only 5% of rare diseases have an approved treatment available, therefore patients often utilise complementary and integrative medicines (CIMs) to help manage their condition. Limited high-quality evidence-based studies are available which support the effectiveness of CIM, as it is difficult to show that an outcome is a direct result of the CIM intervention and not due to bias. Patients and healthcare professionals must weigh up the evidence quality, safety, efficacy, practical logistics, and financial implications of utilising CIM for rare diseases. This study aimed to elucidate perspectives of stakeholders (individuals with rare diseases, carers, family members, CIM practitioners and healthcare professionals), on the usage of CIM for rare diseases across Northern Ireland.

METHODS: This was a mixed methods study. An online survey was open from January to February 2019 (n = 29 responses). Themes identified from the survey were then discussed with stakeholders in a semi-structured discussion workshop in March 2019.

RESULTS: A limited number of participants responded to the survey (n = 29). Some individuals with rare diseases reported CIM as effective in the management of their condition, in particular acupuncture, dietary supplements, herbal medicines, homoeopathy, hydrotherapy, kinesiology, mindfulness, pilates, reflexology, tai chi, and yoga. However, a number of respondents (n = 7) experienced a negative side effect from CIM. Workshop participants raised concerns over the lack of information available about CIM and rare disease. Both the survey and workshop identified inequality of access with participants reporting CIM to be expensive.

CONCLUSIONS: More information, high-quality research, and education about CIM are required for patients and healthcare professionals to help make informed decisions about the usage of CIM for rare diseases. Improved communication, information, and health and social care in general would help individuals be more confident and knowledgeable about therapeutic options in relation to their rare disease(s).

UNLABELLED: Nur für fünf Prozent der seltenen Erkrankungen existiert eine zugelassene Behandlung, weshalb Patienten häufig komplementäre und integrative Medizin (CIM) nutzen, um ihre Krankheit zu behandeln. Es liegen nur wenige qualitativ hochwertige evidenzbasierte Studien vor, die die Wirksamkeit von CIM stützen, da sich schwer nachweisen lässt, dass ein Behandlungsergebnis direkt durch die CIM-Intervention bedingt und nicht Folge einer Verzerrung ist. Patienten und Angehörige der Gesundheitsberufe müssen die Qualität der Evidenz, die Sicherheit und Wirksamkeit sowie praktische logistische Aspekte und die finanziellen Folgen der Anwendung von CIM bei seltenen Erkrankungen abwägen. Mit der vorliegenden Studie sollte die Perspektive der Betroffenen (Menschen mit seltenen Erkrankungen, Betreuungspersonen, Familienangehörige, CIM-Praktiker und Angehörige der Gesundheitsberufe) in Bezug auf die Anwendung von CIM bei seltenen Erkrankungen in Nordirland untersucht werden.Es handelte sich um eine Studie mit gemischten Methoden. Eine Online-Umfrage war von Januar bis Februar 2019 geöffnet (n = 29 Antworten). Die in der Umfrage ermittelten Themen wurden anschließend im März 2019 im Rahmen eines halbstrukturierten Diskussionsworkshops mit den Betroffenen erörtert.Eine begrenzte Anzahl von Teilnehmern antwortete auf die Umfrage (n = 29). Einige Personen mit seltenen Erkrankungen gaben an, dass CIM bei der Behandlung ihrer Erkrankung wirksam war, insbesondere Akupunktur, Nahrungsergänzungsmittel, pflanzliche Arzneimittel, Homöopathie, Hydrotherapie, Kinesiologie, Achtsamkeit, Pilates, Reflexologie, Tai Chi und Yoga. Einige Befragte (n = 7) berichteten jedoch über negative Nebenwirkungen der CIM. Die Workshop-Teilnehmer äußerten Bedenken in Bezug auf den Mangel an Informationen über CIM und seltene Erkrankungen. Sowohl in der Umfrage als auch im Workshop zeigte sich eine Ungleichheit beim Zugang zu CIM und die Teilnehmer berichteten, dass CIM teuer sei.Patienten und Angehörige der Gesundheitsberufe benötigen mehr Informationen, qualitativ hochwertige Forschung und Aufklärung über CIM, um fundierte Entscheidungen über die Anwendung von CIM bei seltenen Erkrankungen treffen zu können. Eine bessere Kommunikation, Information sowie gesundheitliche und soziale Versorgung im Allgemeinen würden zu mehr Selbstvertrauen und Wissen der Betroffenen über die therapeutischen Möglichkeiten im Zusammenhang mit ihrer seltenen Erkrankung beitragen.},

OBJECTIVE: Presentation of early stages of neurodegenerative diseases, diagnostic procedures for the early detection and possible treatment consequences.

MATERIAL AND METHODS: Selective literature search, discussion of basic research and expert recommendations.

RESULTS: Many neurodegenerative diseases have a prodromal phase preceding the manifest disease that can be diagnosed with current criteria. In this prodromal phase, those affected are often oligosymptomatic but in some cases can already be identified using biomarkers. These developments are already taken into account in diagnostic criteria for some of these prodromal phases. The prodromal phase, in turn, is preceded by an asymptomatic phase which, however, already shows molecular changes and can be identified by biomarkers in some diseases. The early identification and stratification of patients is particularly important when planning studies for disease-modifying treatment, and biomarkers are already being used in clinical trials for this purpose.

DISCUSSION: Biomarker-based identification of individuals in the prodromal phase of neurodegenerative diseases is already possible for some entities. People who show the first signs of a neurodegenerative disease can be referred to centers for clinical trials and observational studies.},

Nanotechnology has recently come to light as a viable strategy for overcoming this obstacle and improving drug delivery to the brain. With a focus on current developments and prospects, this review article examines the use of nanoparticles to overcome the BBB constraints to improve drug therapy for AD The potential for several nanoparticle-based approaches, such as those utilizing lipid-based, polymeric, and inorganic nanoparticles, to enhance drug transport across the BBB are highlighted. To shed insight on their involvement in aiding effective drug transport to the brain, methods of nanoparticle-mediated drug delivery, such as surface modifications, functionalization, and particular targeting ligands, are also investigated. The article also discusses the most recent findings on innovative medication formulations encapsulated within nanoparticles and the therapeutic effects they have shown in both preclinical and clinical testing. This sector has difficulties and restrictions, such as the need for increased safety, scalability, and translation to clinical applications. However, the major emphasis of this review aims to provide insight and contribute to the knowledge of how nanotechnology can potentially revolutionize the worldwide treatment of NDDs, particularly AD, to enhance clinical outcomes.},

Approximately 15% of the total population of the world is affected by some form of NDs, resulting in physical and cognitive disability. The most common NDs include Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. Although NDs are caused by a complex interaction of genetic, environmental, and lifestyle variables, neuroinflammation is known to be associated with all NDs, often leading to permanent damage to neurons of the central nervous system. Furthermore, numerous emerging pieces of evidence have demonstrated that inflammation not only supports the progression of NDs but can also serve as an initiator. Hence, various medicines capable of preventing or reducing neuroinflammation have been investigated as ND treatments. While anti-inflammatory medicine has shown promising benefits in several preclinical models, clinical outcomes are often questionable. In this review, we discuss various NDs with their current treatment strategies, the role of neuroinflammation in the pathophysiology of NDs, and the use of anti-inflammatory agents as a potential therapeutic option.},

abstract = {BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder affecting upper and lower motor neurons. Some ALS patients exhibit concomitant nonmotor signs; thus, ALS is considered a multisystemic disorder. Pain is an important nonmotor symptom. Observational and case-control studies report high frequency of pain in ALS patients and it has been correlated with depression and quality of life. There are no specific scales for the assessment of pain and no randomized controlled trials (RCTs) regarding the drug management of pain in ALS.

AIM: To systematically review the evidence for the nonpharmacological interventions (NPIs) in relieving pain in ALS, on March 2024, we searched the following databases: Pubmed, Scopus, Web of Science, and Cochrane. We also checked the bibliographies of trials identified to include further published or unpublished trials.

MAIN RESULTS: A total of 1003 records were identified. Finally, five RCTs including 131 patients (64 in the intervention group and 67 in the control group) were included for meta-analysis. The interventions of the included RCTs consisted of muscle exercise, combined aerobics-strength intervention, and osteopathic manual treatment. The meta-analysis did not find a statistically significant difference in favor of NPIs for alleviating pain in ALS patients.

CONCLUSIONS: ALS has a fulminant course and irreversibly leads to death. Pain in ALS patients, although a common nonmotor symptom, is often unrecognized and undertreated, and this is underlined by the lack of any RCTs on drug therapy for pain. Albeit NPIs are considered safe, as adverse effects are rarely reported, this systematic review did not provide sufficient evidence for a beneficial effect on pain. The scarceness of relevant literature highlights the need for future studies, with larger samples, more homogeneous in terms of interventions and population characteristics (stage of disease), and better choice of measurement scales to further investigate the efficacy, if any, of various pain interventions in ALS patients.},

abstract = {Neurodegenerative diseases (NDDs) such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis epitomize a class of insidious and relentless neurological conditions that are difficult to cure. Conventional therapeutic regimens often fail due to the late onset of symptoms, which occurs well after irreversible neurodegeneration has begun. The integrity of the blood-brain barrier (BBB) further impedes efficacious drug delivery to the central nervous system, presenting a formidable challenge in the pharmacological treatment of NDDs. Recent scientific inquiries have shifted focus toward the peripheral biological systems, investigating their influence on central neuropathology through the lens of extracellular vesicles (EVs). These vesicles, distinguished by their ability to breach the BBB, are emerging as dual operatives in the context of NDDs, both as conveyors of pathogenic entities and as prospective vectors for therapeutic agents. This review critically summarizes the burgeoning evidence on the role of extracerebral EVs, particularly those originating from bone, adipose tissue, and gut microbiota, in modulating brain pathophysiology. It underscores the duplicity potential of peripheral EVs as modulators of disease progression and suggests their potential as novel vehicles for targeted therapeutic delivery, positing a transformative impact on the future landscape of NDD treatment strategies. Search strategy A comprehensive literature search was conducted using PubMed, Web of Science, and Scopus from January 2000 to December 2023. The search combined the following terms using Boolean operators: "neurodegenerative disease" OR "Alzheimer's disease" OR "Parkinson's disease" OR "Amyotrophic lateral sclerosis" AND "extracellular vesicles" OR "exosomes" OR "outer membrane vesicles" AND "drug delivery systems" AND "blood-brain barrier". MeSH terms were employed when searching PubMed to refine the results. Studies were included if they were published in English, involved human subjects, and focused on the peripheral origins of EVs, specifically from bone, adipose tissue, and gut microbiota, and their association with related diseases such as osteoporosis, metabolic syndrome, and gut dysbiosis. Articles were excluded if they did not address the role of EVs in the context of NDDs or did not discuss therapeutic applications. The titles and abstracts of retrieved articles were screened using a dual-review process to ensure relevance and accuracy. The reference lists of selected articles were also examined to identify additional relevant studies.},

The advent of highly sensitive analytical platforms that enable reliable quantification of neurofilaments in blood samples and simplify longitudinal follow-up has paved the way for the development of neurofilaments as a biomarker in clinical practice. Potential applications include assessment of disease activity, monitoring of treatment responses, and determining prognosis in many acute and chronic neurological disorders as well as their use as an outcome measure in trials of novel therapies. Progress has now moved the measurement of neurofilaments to the doorstep of routine clinical practice for the evaluation of individuals.

We then discuss analytical and statistical approaches and challenges in determining neurofilament levels in different clinical contexts and assess the implications of neurofilament light chain (NfL) levels in normal ageing and the confounding factors that need to be considered when interpreting NfL measures. In addition, we summarize the current value and potential clinical applications of neurofilaments as a biomarker of neuro-axonal damage in a range of neurological disorders, including multiple sclerosis, Alzheimer disease, frontotemporal dementia, amyotrophic lateral sclerosis, stroke and cerebrovascular disease, traumatic brain injury, and Parkinson disease. We also consider the steps needed to complete the translation of neurofilaments from the laboratory to the management of neurological diseases in clinical practice.},

In this amyotrophic lateral sclerosis clinical trial, the safety, tolerability, CNS penetrance, and modulation of pharmacodynamic target engagement biomarkers were evaluated. This Phase 2a, randomized, double-blind, placebo-controlled, biomarker-endpoint clinical trial was conducted in four USA centres (ClinicalTrials.gov NCT05163886). Participants with C9orf72 repeat expansion were randomly assigned (2:1) to receive twice-daily oral treatment of 125 mg apilimod dimesylate capsules or matching placebo for 12 weeks, followed by a 12-week open-label extension. Safety was measured as the occurrence of treatment-emergent adverse or serious adverse events attributable to study drug, and tolerability as trial completion on treatment over 12 weeks. Changes from baseline in plasma and CSF and concentrations of apilimod and its active metabolites and of pharmacodynamic biomarkers of PIKfyve inhibition (soluble glycoprotein nonmetastatic melanoma protein B [sGPNMB] upregulation) and disease-specific CNS target engagement (poly[GP]). Between Dec 16, 2021, and Jul 7, 2022, 15 eligible participants were enrolled. There were no drug-related serious adverse events reported in the trial. Fourteen (93%) participants completed the double-blind period with 99% dose compliance (N=9 [90%] apilimod dimesylate; N=5 [100%] placebo). At Week 12, apilimod dimesylate was measurable in CSF at 1.63 ng/mL (SD: 0.937). At Week 12, apilimod dimesylate increased plasma sGPNMB by > 2.5-fold (p < 0.001) indicating PIKfyve inhibition and lowered CSF poly(GP) protein levels by 73% (p < 0.001) indicating CNS tissue-level proof of mechanism. Apilimod dimesylate met prespecified key safety and biomarker endpoints in this Phase 2a trial and demonstrated CNS penetrance and pharmacodynamic target engagement. Apilimod dimesylate was observed to have the greatest reduction in CSF poly(GP) levels observed to date in C9orf72 clinical trials.},

abstract = {This chapter discusses comprehensive neurophysiological biomarkers utilised in motor neuron disease (MND) and, in particular, its commonest form, amyotrophic lateral sclerosis (ALS). These encompass the conventional techniques including nerve conduction studies (NCS), needle and high-density surface electromyography (EMG) and H-reflex studies as well as novel techniques. In the last two decades, new methods of assessing the loss of motor units in a muscle have been developed, that are more convenient than earlier methods of motor unit number estimation (MUNE),and may use either electrical stimulation (e.g. MScanFit MUNE) or voluntary activation (MUNIX). Electrical impedance myography (EIM) is another novel approach for the evaluation that relies upon the application and measurement of high-frequency, low-intensity electrical current. Nerve excitability techniques (NET) also provide insights into the function of an axon and reflect the changes in resting membrane potential, ion channel dysfunction and the structural integrity of the axon and myelin sheath. Furthermore, imaging ultrasound techniques as well as magnetic resonance imaging are capable of detecting the constituents of morphological changes in the nerve and muscle. The chapter provides a critical description of the ability of each technique to provide neurophysiological insight into the complex pathophysiology of MND/ALS. However, it is important to recognise the strengths and limitations of each approach in order to clarify utility. These neurophysiological biomarkers have demonstrated reliability, specificity and provide additional information to validate and assess lower motor neuron dysfunction. Their use has expanded the knowledge about MND/ALS and enhanced our understanding of the relationship between motor units, axons, reflexes and other neural circuits in relation to clinical features of patients with MND/ALS at different stages of the disease. Taken together, the ultimate goal is to aid early diagnosis, distinguish potential disease mimics, monitor and stage disease progression, quantify response to treatment and develop potential therapeutic interventions.},

This systematic review aims to highlight the safety of the procedures, their tolerability, and efficacy of the available therapies conducted over the years using mesenchymal stem cells (MSCs) in treating the neurological conditions mentioned above.

METHODS: PubMed was used to search for published data from clinical trials performed using mesenchymal stem cells. Studies that provided the necessary information that mentioned the efficacy and adverse effects of the treatment in patients were considered for this review.

RESULTS: In total, 43 manuscripts were selected after a strategic search, and these studies have been included in this systematic review. Most included studies reported the safety of the procedures used and the treatment's good tolerability, with mild adverse events such as fever, headache, mild pain at the injection site, or nausea being common. A few studies also reported death of some patients, attributed to the progression of the disease to severe stages before the treatment. Other severe events, such as respiratory or urinary infections reported in some studies, were not related to the treatment. Different parameters were used to evaluate the efficacy of the treatment based on the clinical condition of the patient.

CONCLUSION: Mesenchymal stem cells transplantation has so far proven to be safe and tolerable in select studies and patient types. This systematic review includes the results from the 43 selected studies in terms of safety and tolerability of the procedures, and several adverse events and therapeutic benefits during the follow-up period after administration of MSCs.},

abstract = {Neurodegenerative disorders (NDs) are among the most common causes of death across the globe. NDs are characterized by progressive damage to CNS neurons, leading to defects in specific brain functions such as memory, cognition, and movement. The most common NDs are Parkinson's, Alzheimer's, Huntington's, and amyotrophic lateral sclerosis (ALS). Despite extensive research, no therapeutics or medications against NDs have been proven to be effective. The current treatment of NDs involving symptom-based targeting of the disease pathogenesis has certain limitations, such as drug resistance, adverse side effects, poor blood-brain barrier permeability, and poor bioavailability of drugs. Some studies have shown that plant-derived natural compounds hold tremendous promise for treating and preventing NDs. Therefore, the primary objective of this review article is to critically analyze the properties and potency of some of the most studied phytomedicines, such as quercetin, curcumin, epigallocatechin gallate (EGCG), apigenin, and cannabinoids, and highlight their advantages and limitations for developing next-generation alternative treatments against NDs. Further extensive research on pre-clinical and clinical studies for developing plant-based drugs against NDs from bench to bedside is warranted.},

abstract = {(Macro)autophagy is a cellular degradation system for unnecessary materials, such as aggregate-prone TDP-43, a central molecule in neurodegenerative diseases including amyotrophic lateral sclerosis and frontotemporal lobar degeneration. Abemaciclib (Abe) and vacuolin-1 (Vac) treatments are known to induce vacuoles characterized by an autophagosome and a lysosome component, suggesting that they facilitate autophagosome-lysosome fusion. However, it remains unknown whether Abe and Vac suppress the accumulation of aggregate-prone TDP-43 by accelerating autophagic flux. In the present study, the Abe and Vac treatment dose-dependently reduced the GFP/RFP ratio in SH-SY5Y neuroblastoma cells stably expressing the autophagic flux marker GFP-LC3-RFP-LC3ΔG. Abe and Vac also increased the omegasome marker GFP-ATG13 signal and the autophagosome marker mCherry-LC3 localized to the lysosome marker LAMP1-GFP. The Abe and Vac treatment decreased the intracellular level of the lysosome marker LAMP1-GFP in SH-SY5Y cells stably expressing LAMP1-GFP, but did not increase the levels of LAMP1-GFP, the autophagosome marker LC3-II, or the multivesicular body marker TSG101 in the extracellular vesicle-enriched fraction. Moreover, Abe and Vac treatment autophagy-dependently inhibited GFP-tagged aggregate-prone TDP-43 accumulation. The results of a PI(3)P reporter assay using the fluorescent protein tagged-2 × FYVE and LAMP1-GFP indicated that Abe and Vac increased the intensity of the PI(3)P signal on lysosomes. A treatment with the VPS34 inhibitor wortmannin (WM) suppressed Abe-/Vac-facilitated autophagic flux and the degradation of GFP-tagged aggregate-prone TDP-43. Collectively, these results suggest that Abe and Vac degrade aggregate-prone TDP-43 by accelerating autophagosome formation and autophagosome-lysosome fusion through the formation of PI(3)P.},

abstract = {INTRODUCTION/AIMS: Biomarkers have shown promise in amyotrophic lateral sclerosis (ALS) research, but the quest for reliable biomarkers remains active. This study evaluates the effect of debamestrocel on cerebrospinal fluid (CSF) biomarkers, an exploratory endpoint.

METHODS: A total of 196 participants randomly received debamestrocel or placebo. Seven CSF samples were to be collected from all participants. Forty-five biomarkers were analyzed in the overall study and by two subgroups characterized by the ALS Functional Rating Scale-Revised (ALSFRS-R). A prespecified model was employed to predict clinical outcomes leveraging biomarkers and disease characteristics. Causal inference was used to analyze relationships between neurofilament light chain (NfL) and ALSFRS-R.

RESULTS: We observed significant changes with debamestrocel in 64% of the biomarkers studied, spanning pathways implicated in ALS pathology (63% neuroinflammation, 50% neurodegeneration, and 89% neuroprotection). Biomarker changes with debamestrocel show biological activity in trial participants, including those with advanced ALS. CSF biomarkers were predictive of clinical outcomes in debamestrocel-treated participants (baseline NfL, baseline latency-associated peptide/transforming growth factor beta1 [LAP/TGFβ1], change galectin-1, all p < .01), with baseline NfL and LAP/TGFβ1 remaining (p < .05) when disease characteristics (p < .005) were incorporated. Change from baseline to the last measurement showed debamestrocel-driven reductions in NfL were associated with less decline in ALSFRS-R. Debamestrocel significantly reduced NfL from baseline compared with placebo (11% vs. 1.6%, p = .037).

DISCUSSION: Following debamestrocel treatment, many biomarkers showed increases (anti-inflammatory/neuroprotective) or decreases (inflammatory/neurodegenerative) suggesting a possible treatment effect. Neuroinflammatory and neuroprotective biomarkers were predictive of clinical response, suggesting a potential multimodal mechanism of action. These results offer preliminary insights that need to be confirmed.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is a devastating, immensely complex neurodegenerative disease by lack of effective treatments. To date, the challenge to establishing effective treatment for ALS remains formidable, partly due to inadequate translation of existing human genetic findings into actionable ALS-specific pathobiology for subsequent therapeutic development. This study evaluates the feasibility of network medicine methodology via integrating human brain-specific multi-omics data to prioritize drug targets and repurposable treatments for ALS. Using human brain-specific genome-wide quantitative trait loci (x-QTLs) under a network-based deep learning framework, we identified 105 putative ALS-associated genes enriched in various known ALS pathobiological pathways, including regulation of T cell activation, monocyte differentiation, and lymphocyte proliferation. Specifically, we leveraged non-coding ALS loci effects from genome-wide associated studies (GWAS) on brain-specific expression quantitative trait loci (QTL) (eQTL), protein QTLs (pQTL), splicing QTL (sQTL), methylation QTL (meQTL), and histone acetylation QTL (haQTL). Applying network proximity analysis of predicted ALS-associated gene-coding targets and existing drug-target networks under the human protein-protein interactome (PPI) model, we identified a set of potential repurposable drugs (including Diazoxide, Gefitinib, Paliperidone, and Dimethyltryptamine) for ALS. Subsequent validation established preclinical and clinical evidence for top-prioritized repurposable drugs. In summary, we presented a network-based multi-omics framework to identify potential drug targets and repurposable treatments for ALS and other neurodegenerative disease if broadly applied.},

Cerebrolysin is a drug candidate for the treatment of ALS because of its neuroprotective and neuroregenerative effects. We initiated a pilot clinical study of a combination of Cerebrolysin and riluzole to assess the therapeutic benefit of Cerebrolysin as an add-on treatment on clinical signs and symptoms in outpatients with ALS. Twenty patients with a clinically definitive diagnosis of ALS were enrolled and randomly assigned in a 1:1 ratio to receive Cerebrolysin or placebo. All patients received 50 mg of riluzole PO twice daily as a standard treatment. Patients in the Cerebrolysin group received intravenous injections of 10 mL of Cerebrolysin once daily, five days a week for the first month and three days a week for the next two months. Analysis of the ALS Functional Rating Scale - revised at Month 1 (primary outcome measure), showed a significant treatment effect in favor of Cerebrolysin with a 2.3-point improvement from baseline to Month 1 compared to a 0.9-point decrease in patients on placebo (P=0.005). The effect was maintained over the three-month study period, and the beneficial effect of Cerebrolysin over placebo was also evident in the secondary outcome measures. The safety analysis showed that the combination of riluzole and Cerebrolyisn was well tolerated. Our results demonstrate for the first time a significant clinical effect of Cerebrolysin in improving functional outcomes in patients with ALS and suggest that Cerebrolysin has potential as a novel therapeutic option for ALS.},

Here, we evaluate the ability of an accelerometer-derived outcome to detect differential clinical disease progression and assess its longitudinal associations with overall survival in patients with ALS.

METHODS: Patients with ALS wore an accelerometer on the hip for 3-7 days, every 2-3 months during a multi-year observation period. An accelerometer-derived outcome, the Vertical Movement Index (VMI), was calculated, together with predicted disease progression rates, and jointly analysed with overall survival. The clinical utility of VMI was evaluated using comparisons to patient-reported functionality, while the impact of various monitoring schemes on empirical power was explored through simulations.

FINDINGS: In total, 97 patients (70.1% male) wore the accelerometer for 1995 days, for a total of 27,701 h. The VMI was highly discriminatory for predicted disease progression rates, revealing faster rates of decline in patients with a worse predicted prognosis compared to those with a better predicted prognosis (p < 0.0001). The VMI was strongly associated with the hazard for death (HR 0.20, 95% CI: 0.09-0.44, p < 0.0001), where a decrease of 0.19-0.41 unit was associated with reduced ambulatory status. Recommendations for future studies using accelerometery are provided.

INTERPRETATION: The results serve as motivation to incorporate accelerometer-derived outcomes in clinical trials, which is essential for further validation of these markers to meaningful endpoints.

abstract = {OBJECTIVE: While the cognitive-behavioral characteristics of amyotrophic lateral sclerosis (ALS) patients carrying C9orf72 pathological repeat expansion have been extensively studied, our understanding of those carrying SOD1 variants is mostly based on case reports. The aim of this paper is to extensively explore the cognitive-behavioral characteristics of a cohort of ALS patients carrying pathogenetic variants of SOD1 gene, comparing them to patients without pathogenetic variants of 46 ALS-related genes (wild-type [WT]-ALS) and healthy controls.

METHODS: All ALS patients seen at the Turin ALS expert center in the 2009-2021 period who underwent both cognitive/behavioral and extensive genetic testing were eligible to be included in the study. Only patients with SOD1 pathogenetic variants (n = 28) (SOD1-ALS) and WT-ALS (n = 829) were enrolled in the study. A series of 129 controls was also included.

RESULTS: Among the 28 SOD1-ALS patients, 16 (57.1%) had normal cognitive function, 5 (17.9%) isolated cognitive impairment (ALSci) (17.9%), 6 (21.4%) isolated behavioral impairment (ALSbi), 1 (3.6%) cognitive and behavioral impairment (ALScbi), and no one ALS-FTD. SOD1-ALS performed worse than controls in all explored domains, in particular Social Cognition and Language domains. SOD1-ALS patients had similar scores in all tests compared to WT-ALS, except the Story-based Empathy Task (SET), where they performed worse.

INTERPRETATION: Cognitive-behavioral impairment is much more common in SOD1 patients than previously assumed. SOD1-ALS are characterized by a more frequent impairment of Social Cognition and, less markedly, of Language domains. These findings have relevant implication both in the clinical and in the research setting, also considering recently approved treatment for SOD1-ALS. ANN NEUROL 2024.},

abstract = {BACKGROUND: Residential care/assisted living (RC/AL) is an increasingly common place of end-of-life care for persons with Alzheimer's disease and related dementia (ADRD), who have unique care needs as their health declines. Approximately 22% of RC/ALs provide specialized memory care (memory-care RC/AL). Understanding how end-of-life outcomes differ by memory care among residents with ADRD could facilitate aging/dying in place for this population. The objective of this paper is to examine if end-of-life outcomes (i.e., mortality, hospice use, and number of days receiving hospice in the last month of life) differ between residents with ADRD who moved to memory-care RC/AL, compared with residents with ADRD who moved to RC/AL without memory care (general RC/AL).

METHODS: Prospective cohort of 15,152 fee-for-service Medicare beneficiaries with ADRD who moved to large RC/AL (> = 25 beds) between 2016 and 2018. We used inverse probability treatment weighting to account for observable differences between memory-care and general RC/AL residents. Two-part models estimated the difference by memory care in the number of days receiving hospice care in the last months of life among RC/AL decedents.

RESULTS: The unadjusted mortality rates were 13.4% in general RC/AL and 15.8% in memory-care RC/AL with an adjusted difference of 1.3 percentage points higher mortality among memory-care RC/AL residents (p = 0.04). Hospice use was 8% and 10.6% among general and memory-care RC/AL residents, respectively, with an adjusted difference of 1.4 percentage points (p = 0.01) higher in memory care. Two-part models showed that decedents in memory-care RC/AL spent about 1.4 more days receiving hospice care in the last month of life (p = 0.02).

CONCLUSION: We find a higher mortality rate and higher rate of hospice use among memory-care RC/AL residents. These findings suggest that memory care may attract residents closer to the end of life and/or promote hospice use at the end of life.},

No statistically significant relationships or differences occurred between the ALS-CBS or its subsections and the variables measured with exception of age and the attention subsection. Older participants had lower ALS-CBS attention subsection scores. Based on the ALS-CBS scores, most participants had some degree of cognitive impairments: 43 had suspected cognitive impairment, 8 had suspected FTD; 18 fell within the normal range of cognitive function. Overall, the variables of sex, education, time post-diagnosis, and severity of symptoms do not appear to influence ALS-CBS scores. It is recommended cognitive screenings be completed for all PALS due to the high risk for developing cognitive impairments and FTD. Such knowledge can help clinicians develop assessment and treatment plans.},

The NHS provides treatment at the onset of a condition but after that, there is a huge need for ongoing support. Research shows that those who are supported and know more about their condition are less likely to have to call on further in-hospital and GP care. There is enormous scope for improving the quality of life for those with neurological conditions. The right support-therapeutic and social-makes all the difference. The book, which this article is based on, shows how those with neurological conditions benefit from integrated ongoing support provided in the local community and self-help, and how lives can be improved. It explains good practice and encouraging methods in the support and treatment of those with life changing conditions.},

Thus, STING pathway inhibitors could have therapeutic application in many of these inflammatory conditions. The cGAS inhibitor RU.521 and the STING inhibitor H-151 have shown promise as therapeutics in mouse models of colitis, ALS, and more. However, these agents require frequent high-dose intraperitoneal injections, which may limit translatability. Furthermore, long-term use of systemically administered cGAS/STING inhibitors may leave patients vulnerable to viral infections and cancer. Thus, localized or targeted inhibition of the cGAS/STING pathway may be an attractive, broadly applicable treatment for a variety of STING pathway-driven ailments. Here we describe STING-Pathway Inhibiting Nanoparticles (SPINS)-poly(lactic-co-glycolic acid) (PLGA) nanoparticles loaded with RU.521 and H-151-as a platform for enhanced and sustained inhibition of cGAS/STING signaling. We demonstrate that SPINs are equally or more effective at inhibiting type-I interferon responses induced by cytosolic DNA than free H-151 or RU.521. Additionally, we describe a SPIN formulation in which PLGA is coemulsified with poly(benzoyloxypropyl methacrylamide) (P(HPMA-Bz)), which significantly improves drug loading and allows for tunable release of H-151 over a period of days to over a week by varying P(HPMA-Bz) content. Finally, we find that all SPIN formulations were as potent or more potent in inhibiting cGAS/STING signaling in primary murine macrophages, resulting in decreased expression of inflammatory M1-like macrophage markers. Therefore, our study provides an in vitro proof-of-concept for nanoparticle delivery of STING pathway inhibitors and positions SPINs as a potential platform for slowing or reversing the onset or progression of cGAS/STING-driven inflammatory conditions.},

abstract = {INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a rare and fatal neurological disease that leads to progressive motor function degeneration. Diagnosing ALS is challenging due to the absence of a specific detection test. The use of artificial intelligence (AI) can assist in the investigation and treatment of ALS.

METHODS: We searched seven databases for literature on the application of AI in the early diagnosis and screening of ALS in humans. The findings were summarized using random-effects summary receiver operating characteristic curve. The risk of bias (RoB) analysis was carried out using QUADAS-2 or QUADAS-C tools.

RESULTS: In the 34 analyzed studies, a meta-prevalence of 47% for ALS was noted. For ALS detection, the pooled sensitivity of AI models was 94.3% (95% CI - 63.2% to 99.4%) with a pooled specificity of 98.9% (95% CI - 92.4% to 99.9%). For ALS classification, the pooled sensitivity of AI models was 90.9% (95% CI - 86.5% to 93.9%) with a pooled specificity of 92.3% (95% CI - 84.8% to 96.3%). Based on type of input for classification, the pooled sensitivity of AI models for gait, electromyography, and magnetic resonance signals was 91.2%, 92.6%, and 82.2%, respectively. The pooled specificity for gait, electromyography, and magnetic resonance signals was 94.1%, 96.5%, and 77.3%, respectively.

CONCLUSIONS: Although AI can play a significant role in the screening and diagnosis of ALS due to its high sensitivities and specificities, concerns remain regarding quality of evidence reported in the literature.},

abstract = {Neurodegenerative disorders, which include Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), represent a significant and growing global health challenge. Current therapies predominantly focus on symptom management rather than altering disease progression. In this review, we discuss the major therapeutic strategies in practice for these disorders, highlighting their limitations. For AD, the mainstay treatments are cholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonists. For PD, dopamine replacement therapies, including levodopa, are commonly used. HD is managed primarily with symptomatic treatments, and reusable extends survival in ALS. However, none of these therapies halts or substantially slows the neurodegenerative process. In contrast, this review highlights emerging research into bioactive peptides as potential therapeutic agents. These naturally occurring or synthetically designed molecules can interact with specific cellular targets, potentially modulating disease processes. Preclinical studies suggest that bioactive peptides may mitigate oxidative stress, inflammation, and protein misfolding, which are common pathological features in neurodegenerative diseases. Clinical trials using bioactive peptides for neurodegeneration are limited but show promising initial results. For instance, hemiacetal, a γ-secretase inhibitor peptide, has shown potential in AD by reducing amyloid-beta production, though its development was discontinued due to side effects. Despite these advancements, many challenges remain, including identifying optimal peptides, confirming their mechanisms of action, and overcoming obstacles related to their delivery to the brain. Future research should prioritize the discovery and development of novel bioactive peptides and improve our understanding of their pharmacokinetics and pharmacodynamics. Ultimately, this approach may lead to more effective therapies for neurodegenerative disorders, moving beyond symptom management to potentially modify the course of these devastating diseases.},

Among many stem cell types, mesenchymal stem cells (MSCs) that are comprised of heterogenous population are widely used for clinical applications with the expectation of pleiotropic bystander effects. Muse cells are pluripotent-like/macrophage-like stem cells distributed in the bone marrow, peripheral blood, and organ connective tissues as cells positive for the pluripotent surface marker stage-specific-embryonic antigen -3. Muse cells comprise ~1% to several percent of MSCs. While Muse cells and MSCs share several characteristics, such as mesenchymal surface marker expression and their bystander effects, Muse cells exhibit unique characteristics not observed in MSCs. These unique characteristics of Muse cells include selective homing to damaged tissue after intravenous injection rather than being trapped in the lung like MSCs, replacement of a wide range of damaged/apoptotic cells by differentiation through phagocytosis, and long-lasting immunotolerance for donor cell use. In this review, we focus on the basic properties of Muse cells clarified through preclinical studies and clinical trials conducted by intravenous injection of donor-Muse cells without HLA-matching tests or immunosuppressant treatment. MSCs are considered to differentiate into osteogenic, chondrogenic, and adipogenic cells, whereas the range of their differentiation has long been debated. Muse cells may provide clues to the wide-ranging differentiation potential of MSCs that are observed with low frequency. Furthermore, the utilization of Muse cells may provide a novel strategy for clinical treatment.},

In this study, the genetic makeup of ALS is investigated, with a focus on the SOD1 gene's single-nucleotide polymorphisms (SNPs) and their ability to affect disease risk. Eleven high-risk missense variations that may impair the functionality of the SOD1 protein were discovered after a thorough examination of SNPs in the SOD1 gene. These mutations were chosen using a variety of prediction approaches, highlighting their importance in the aetiology of ALS. Notably, it was discovered that the stability of the SOD1 wild-type protein structure was compromised by the G38R and G42D SOD1 variants. Additionally, Edaravone, a possible ALS medication, showed a greater affinity for binding mutant SOD1 structures, pointing to potential personalised treatment possibilities. The high-risk SNPs discovered in this investigation seem to have functional effects, especially on the stability of proteins and their interactions with other molecules. This study clarifies the complex genetics of ALS and offers insights into how these genetic variations may affect the effectiveness of therapeutic interventions, particularly in the context of edaravone. In this study advances our knowledge of the genetic mechanisms causing ALS vulnerability and prospective therapeutic strategies. Future studies are necessary to confirm these results and close the gap between individualised clinical applications and improved ALS care.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons, resulting in muscle weakness, paralysis, and eventually patient mortality. In recent years, neuromodulation techniques have emerged as promising potential therapeutic approaches to slow disease progression and improve the quality of life of ALS patients. A systematic review was conducted until August 8, 2023, to evaluate the neuromodulation methods used and their potential in the treatment of ALS. The search strategy was applied in the Cochrane Central database, incorporating results from other databases such as PubMed, Embase, CTgov, CINAHL, and ICTRP. Following the exclusion of papers that did not fulfil the inclusion criteria, a total of 2090 records were found, leaving a total of 10 studies. R software was used to conduct meta-analyses based on the effect sizes between the experimental and control groups. This revealed differences in muscle stretch measures with manual muscle testing (p = 0.012) and resting motor threshold (p = 0.0457), but not with voluntary isometric contraction (p = 0.1883). The functionality of ALS was also different (p = 0.007), but not the quality of life. Although intracortical facilitation was not seen in motor cortex 1 (M1) (p = 0.1338), short-interval intracortical inhibition of M1 was significant (p = 0.0001). BDNF showed no differences that were statistically significant (p = 0.2297). Neuromodulation-based treatments are proposed as a promising therapeutic approach for ALS that can produce effects on muscle function, spasticity, and intracortical connections through electrical, magnetic, and photonic stimulation. Photobiomodulation stands out as an innovative approach that uses specific wavelengths to influence mitochondria, with the aim of improving mitochondrial function and reducing excitotoxicity. The lack of reliable placebo controls and the variation in stimulation frequency are some of the drawbacks of neuromodulation.},

abstract = {The neuromuscular junction (NMJ) is a crucial structure that connects the cholinergic motor neurons to the muscle fibers and allows for muscle contraction and movement. Despite the interruption of the supraspinal pathways that occurs in spinal cord injury (SCI), the NMJ, innervated by motor neurons below the injury site, has been found to remain intact. This highlights the importance of studying the NMJ in rodent models of various nervous system disorders, such as amyotrophic lateral sclerosis (ALS), Charcot-Marie-Tooth disease (CMT), spinal muscular atrophy (SMA), and spinal and bulbar muscular atrophy (SBMA). The NMJ is also involved in myasthenic disorders, such as myasthenia gravis (MG), and is vulnerable to neurotoxin damage. Thus, it is important to analyze the integrity of the NMJ in rodent models during the early stages of the disease, as this may allow for a better understanding of the condition and potential treatment options. The spinal cord also plays a crucial role in the functioning of the NMJ, as the junction relays information from the spinal cord to the muscle fibers, and the integrity of the NMJ could be disrupted by SCI. Therefore, it is vital to study SCI and muscle function when studying NMJ disorders. This review discusses the formation and function of the NMJ after SCI and potential interventions that may reverse or improve NMJ dysfunction, such as exercise, nutrition, and trophic factors.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is considered the prototype of motor neuron disease, characterized by motor neuron loss and muscle waste. A well-established pathogenic hallmark of ALS is mitochondrial failure, leading to bioenergetic deficits. So far, pharmacological interventions for the disease have proven ineffective. Trimetazidine (TMZ) is described as a metabolic modulator acting on different cellular pathways. Its efficacy in enhancing muscular and cardiovascular performance has been widely described, although its molecular target remains elusive. We addressed the molecular mechanisms underlying TMZ action on neuronal experimental paradigms. To this aim, we treated murine SOD1[G93A]-model-derived primary cultures of cortical and spinal enriched motor neurons, as well as a murine motor-neuron-like cell line overexpressing SOD1[G93A], with TMZ. We first characterized the bioenergetic profile of the cell cultures, demonstrating significant mitochondrial dysfunction that is reversed by acute TMZ treatments. We then investigated the effect of TMZ in promoting autophagy processes and its impact on mitochondrial morphology. Finally, we demonstrated the effectiveness of TMZ in terms of the mitochondrial functionality of ALS-rpatient-derived peripheral blood mononuclear cells (PBMCs). In summary, our results emphasize the concept that targeting mitochondrial dysfunction may represent an effective therapeutic strategy for ALS. The findings demonstrate that TMZ enhances mitochondrial performance in motor neuron cells by activating autophagy processes, particularly mitophagy. Although further investigations are needed to elucidate the precise molecular pathways involved, these results hold critical implications for the development of more effective and specific derivatives of TMZ for ALS treatment.},

Nevertheless, the induced pluripotent stem cells (iPS) technology could be the answer, providing disease modelling, drug testing, and cell-based therapies for this pathology. The aim of this work was to conduct a literature review of the past 5 years about the role of iPS in ALS, to better define the neurobiological mechanisms involved in the pathogenesis and the potential future therapies. The review also deals with advanced and currently available technologies used to reprogram cell lines and generate human motor neurons in vitro, which represent the source to study the pathological processes, the relationship between phenotype and genotype, the disease progression and the potential therapeutic targets of these group of disorders. Specific treatment options with stem cells involve Advance Gene Editing Technology, neuroprotective agents, and cells or exosomes transplantation, aimed to replace dead or damaged nerve cells. In summary, this review comprehensively addresses the role of human pluripotent stem cells (hPSCs) in motor neuron diseases (MND), with a focus on physiopathology, diagnostic and prognostic implications, specific and potential future treatment options. Understanding the biological mechanisms and practical implications of hPSCs in MND is crucial for advancing therapeutic strategies and improving outcomes for patients affected by these devastating diseases.},

RESULTS: The article provided a brief literature review, substantiated the potential use of low-level laser therapy for ALS. The particular techniques of LLLT were developed.

CONCLUSION: Based on the results of several studies and many years of successful experience with low-level laser therapy in Russia we conclude that a LLLT technique, including intravenous laser blood illumination (ILBI), noninvasive laser blood illumination (NLBI), and local exposure, is a promising treatment method for ALS.},

However, inflammation is known to play an important role in the development of this condition. To identify driver genes that affect the inflammatory response in amyotrophic lateral sclerosis, as well as potential treatment targets, it is crucial to analyze brain tissue samples from patients with both sporadic amyotrophic lateral sclerosis and C9orf72-related amyotrophic lateral sclerosis. Therefore, in this study we used a network-driven gene analysis tool, NetBID2.0, which is based on SJARACNe, a scalable algorithm for the reconstruction of accurate cellular networks, to experimentally analyze sequencing data from patients with sporadic amyotrophic lateral sclerosis. The results showed that the OSMR gene is pathogenic in amyotrophic lateral sclerosis and participates in the progression of amyotrophic lateral sclerosis by mediating the neuroinflammatory response. Furthermore, there were differences in OSMR activity and expression between patients with sporadic amyotrophic lateral sclerosis and those with C9orf72-related amyotrophic lateral sclerosis. These findings suggest that OSMR may be a diagnostic and prognostic marker for amyotrophic lateral sclerosis.},

In addition to motor symptoms, patients with ALS have a multitude of nonmotor symptoms; in fact, it is currently considered a multisystem disease. The purpose of our narrative review is to evaluate the different types of pain, the correlation between pain and the disease's stages, the pain assessment tools in ALS patients, and the available therapies focusing above all on the benefits of cannabis use. Pain is an underestimated and undertreated symptom that, in the last few years, has received more attention from research because it has a strong impact on the quality of life of these patients. The prevalence of pain is between 15% and 85% of ALS patients, and the studies on the type and intensity of pain are controversial. The absence of pain assessment tools validated in the ALS population and the dissimilar study designs influence the knowledge of ALS pain and consequently the pharmacological therapy. Several studies suggest that ALS is associated with changes in the endocannabinoid system, and the use of cannabis could slow the disease progression due to its neuroprotective action and act on pain, spasticity, cramps, sialorrhea, and depression. Our research has shown high patients' satisfaction with the use of cannabis for the treatment of spasticity and related pain. However, especially due to the ethical problems and the lack of interest of pharmaceutical companies, further studies are needed to ensure the most appropriate care for ALS patients.},

abstract = {INTRODUCTION: Amyotrophic Lateral Sclerosis is a rapidly progressive motor neuron disorder causing severe disability and premature death. Owing to the advances in uncovering ALS pathophysiology, efficient clinical trial design and research advocacy program, several disease-modifying drugs have been approved for treating ALS. Despite this progress, ALS remains a rapidly disabling and life shortening condition. There is a critical need for more effective therapies.

AREAS COVERED: Here, we reviewed the emerging ALS therapeutics undergoing phase II & III clinical trials. To identify the investigational drugs, we searched ALS and phase II/III trials that are active and recruiting or not yet recruiting on clinicaltrials.gov and Pharmaprojects database.

EXPERT OPINION: The current pipeline is larger and more diverse than ever, with drugs targeting potential genetic and retroviral causes of ALS and drugs targeting a wide array of downstream pathways, including RNA metabolism, protein aggregation, integrated stress response and neuroinflammation.We remain most excited about those that target direct causes of ALS, e.g. antisense oligonucleotides targeting causative genes. Drugs that eliminate abnormal protein aggregates are also up-and-coming. Eventually, because of the heterogeneity of ALS pathophysiology, biomarkers that determine which biological events are most important for an individual ALS patient are needed.},

Although a great deal of energy and financial resources have been invested in disease-related research, breakthroughs in therapeutic approaches remain elusive. The breakdown of cells usually happens together with the onset of neurodegenerative diseases. However, the mechanism that triggers neuronal loss is unknown. Lipid peroxidation, which is iron-dependent, causes a specific type of cell death called ferroptosis, and there is evidence its involvement in the pathogenic cascade of neurodegenerative diseases. However, the specific mechanisms are still not well known. The present article highlights the basic processes that underlie ferroptosis and the corresponding signaling networks. Furthermore, it provides an overview and discussion of current research on the role of ferroptosis across a variety of neurodegenerative conditions.},

abstract = {As persistent elevation of transforming growth factor-β (TGF-β) promotes fibrosis of muscles and joints and accelerates disease progression in amyotrophic lateral sclerosis (ALS), we investigated whether inhibition of TGF-β would be effective against both exacerbations. The effects of TGF-β and its inhibitor on myoblasts and fibroblasts were tested in vitro and confirmed in vivo, and the dual action of a TGF-β inhibitor in ameliorating the pathogenic role of TGF-β in ALS mice was identified. In the peripheral neuromuscular system, fibrosis in the muscles and joint cavities induced by excessive TGF-β causes joint contracture and muscular degeneration, which leads to motor dysfunction. In an ALS mouse model, an increase in TGF-β in the central nervous system (CNS), consistent with astrocyte activity, was associated with M1 microglial activity and pro-inflammatory conditions, as well as with neuronal cell death. Treatment with the TGF-β inhibitor halofuginone could prevent musculoskeletal fibrosis, resulting in the alleviation of joint contracture and delay of motor deterioration in ALS mice. Halofuginone could also reduce glial cell-induced neuroinflammation and neuronal apoptosis. These dual therapeutic effects on both the neuromuscular system and the CNS were observed from the beginning to the end stages of ALS; as a result, treatment with a TGF-β inhibitor from the early stage of disease delayed the time of symptom exacerbation in ALS mice, which led to prolonged survival.},

Such advancement could ultimately improve the quality of life and survival rates for ALS patients. Despite more than a decade of research, no miRNA biomarker candidate has been translated into clinical practice. We conducted a systematic review and meta-analysis to quantitatively synthesize data from original studies that analyzed miRNA expression from liquid biopsies via PCR and compared them to healthy controls. Our analysis encompasses 807 miRNA observations from 31 studies, stratified according to their source tissue. We identified consistently dysregulated miRNAs in serum (hsa-miR-3665, -4530, -4745-5p, -206); blood (hsa-miR-338-3p, -183-5p); cerebrospinal fluid (hsa-miR-34a-3p); plasma (hsa-miR-206); and neural-enriched extracellular vesicles from plasma (hsa-miR-146a-5p, -151a-5p, -10b-5p, -29b-3p, and -4454). The meta-analyses provided further support for the upregulation of hsa-miR-206, hsa-miR-338-3p, hsa-miR-146a-5p and hsa-miR-151a-5p, and downregulation of hsa-miR-183-5p, hsa-miR-10b-5p, hsa-miR-29b-3p, and hsa-miR-4454 as consistent indicators of ALS across independent studies. Our findings provide valuable insights into the current understanding of miRNAs' dysregulated expression in ALS patients and on the researchers' choices of methodology.

Much of the management of ALS is supportive with the goal of maximizing patient quality of life. While the Philippines was participative in the "Ice Bucket Challenge" in 2014, it is up for investigation whether substantial changes occurred to improve healthcare for ALS patients. This study aims to evaluate the treatment gaps in the management of ALS in the Philippines through a scoping review. Data on epidemiology, health systems, and pharmacotherapy available regarding ALS in the local setting were synthesized. Nine articles were included. As of July 2023, there were only four indexed studies on ALS from the Philippines. Five of the included articles investigated ALS in Filipino populations but were not authored by Filipinos nor affiliated with Philippine institutions. The available literature showed a distinct lack of local ALS epidemiologic data, as well as limited availability in diagnostic centers, medications, health financing options, and digestible information for Filipinos. The limitations in managing ALS in the country are multifactorial - from political, medical, and social. It is imperative to establish a national database, financing systems, support groups, and accessible diagnostic centers for ALS patients.},

abstract = {AIMS: Increasing nicotinamide adenine dinucleotide (NAD[+]) availability has been proposed as a therapeutic approach to prevent neurodegeneration in amyotrophic lateral sclerosis (ALS). Accordingly, NAD[+] precursor supplementation appears to exert neuroprotective effects in ALS patients and mouse models. The mechanisms mediating neuroprotection remain uncertain but could involve changes in multiple cell types. We investigated a potential direct effect of the NAD[+] precursor nicotinamide mononucleotide (NMN) on the health of cultured iPSC-derived human motor neurons and in motor neurons isolated from two ALS mouse models - i.e., mice overexpressing wild-type TDP-43 or the ALS-linked mutant hSOD1]G93A[.

RESULTS: NMN treatment increased the complexity of neuronal processes in motor neurons isolated from both mouse models and in iPSC-derived human motor neurons. In addition, NMN prevented neuronal death induced by trophic factor deprivation. In mouse and human motor neurons expressing ALS-linked mutant SOD1, NMN induced an increase in glutathione levels, but this effect was not observed in non-transgenic or TDP-43 overexpressing motor neurons. On the other hand, NMN treatment normalized the TDP-43 cytoplasmic mislocalization induced by its overexpression.

INNOVATION: NMN can directly act on motor neurons to increase the growth and complexity of neuronal processes and prevent the death induced by trophic factor deprivation.

CONCLUSION: Our results support a direct beneficial effect of NAD[+] precursor supplementation on the maintenance of the neuritic arbor in motor neurons. Importantly, this was observed in motor neurons isolated from two different ALS models, with and without involvement of TDP-43 pathology, supporting its therapeutic potential in sporadic and familial ALS.},

In this study, we have developed and evaluated Machine Learning (ML) algorithms that integrate Ensemble and Imbalance Learning techniques to classify patients into Short and Non-Short survival groups based on data collected during diagnosis. We aimed to identify individuals at high risk of mortality within 24 months of symptom onset through analysis of patient data commonly encountered in daily clinical practice. Our Ensemble-Imbalance approach underwent evaluation employing six ML algorithms as base classifiers. Remarkably, our results outperformed those of individual algorithms, achieving a Balanced Accuracy of 88% and a Sensitivity of 96%. Additionally, we used the Shapley Additive Explanations framework to elucidate the decision-making process of the top-performing model, pinpointing the most important features and their correlations with the target prediction. Furthermore, we presented helpful tools to visualize and compare patient similarities, offering valuable insights. Confirming the obtained results, our approach could aid physicians in devising personalized treatment plans at the time of diagnosis or serve as an inclusion/exclusion criterion in clinical trials.},

The present review discusses recent advancements in the field of neurodegenerative diseases and therapeutic applications with ongoing clinical trials, featuring new areas of protein misfolding resulting in aggregation. The endogenous accretion of protein fibrils having fibrillar morphology symbolizes the beginning of neuro-disorders. Prognostic amyloidosis is prominent in numerous degenerative infections such as Alzheimer's and Parkinson's disease, Amyotrophic lateral sclerosis (ALS), etc. However, the molecular basis determining the intracellular or extracellular evidence of aggregates, playing a significant role as a causative factor in neurodegeneration is still unclear. Structural conversions and protein self-assembly resulting in the formation of amyloid oligomers and fibrils are important events in the pathophysiology of the disease. This comprehensive review sheds light on the evolving landscape of potential treatment modalities, highlighting the ongoing clinical trials and the potential socio-economic impact of novel therapeutic interventions in the realm of neurodegenerative diseases. Furthermore, many drugs are undergoing different levels of clinical trials that would certainly help in treating these disorders and will surely improve the socio-impact of human life.},

The limited efficacy of current treatments highlights the need for combination therapies targeting multiple aspects of the disease. Niclosamide, an anthelminthic drug listed as an essential medicine, has been repurposed in clinical trials for different diseases due to its anti-inflammatory and anti-fibrotic properties. Niclosamide can inhibit various molecular pathways (e.g., STAT3, mTOR) that are dysregulated in ALS, suggesting its potential to disrupt these altered mechanisms associated with the pathology. We administered niclosamide intraperitoneally to two transgenic murine models, SOD1-G93A and FUS mice, mimicking key pathological processes of ALS. The treatment was initiated at the onset of symptoms, and we assessed disease progression by neurological scores, rotarod and wire tests, and monitored survival. Furthermore, we investigated cellular and molecular mechanisms affected by niclosamide in the spinal cord and muscle of ALS mice. In both models, the administration of niclosamide resulted in a slowdown of disease progression, an increase in survival rates, and an improvement in tissue pathology. This was characterised by reduced gliosis, motor neuron loss, muscle atrophy, and inflammatory pathways. Based on these results, our findings demonstrate that niclosamide can impact multiple pathways involved in ALS. This multi-targeted approach leads to a slowdown in the progression of the disease, positioning niclosamide as a promising candidate for repurposing in the treatment of ALS.},

abstract = {OBJECTIVE: Hormonal substitution with growth hormone in aged patients remains a debated research topic and is rarely initiated in clinical practice. This reluctance may originate from concerns about adverse effects and the uncritical use as an anti-aging agent. Nevertheless, beneficial effects for selected patients suffering from certain acute and chronic illnesses could justify its use at an advanced age. This systematic review analyzes randomized controlled studies of GH interventions in older patients with different comorbidities to assess both, beneficial and harmful effects.

DESIGN: A systematic search strategy was implemented to identify relevant studies from PubMed, MEDLINE, and The Cochrane Library.

INCLUSION CRITERIA: participants aged over 65 years, randomized controlled trials involving human growth hormone (GH) and presence of at least one additional comorbidity independent of a flawed somatotropic axis.

RESULTS: The eight eligible studies encompassed various comorbidities including osteoporosis, frailty, chronic heart failure, hip fracture, amyotrophic lateral sclerosis and hemodialysis. Outcomes varied, including changes in body composition, physical performance, strength, bone mineral density, cardiovascular parameters, quality of life and housing situation. Study protocols differed greatly in GH application frequency (daily, 2nd day or 3×/week), doses (0.41 mg-2.6 mg; mean 1.3 mg per 60 kg patient) and duration (1-12 months; mean 7 months). Mild dose-related side effects were reported, alongside noticeable positive impacts particularly on body composition, functionality, and quality of life.

CONCLUSION: Despite limited evidence, GH treatment might offer diverse benefits with few adverse effects. Further research with IGF-I dependent indication and clear outcomes, incorporating IGF-I dependent GH titration in older adults is warranted.},

RESEARCH DESIGN AND METHODS: A retrospective cohort analysis of a medical claims dataset over a 10 year span was conducted in patients aged 60 years or older. Participants were propensity score matched for comorbidity severity and demographic parameters. Relative risk (RR) ratios and 95% confidence intervals (CI) were determined for age-related NDDs. Cumulative hazard ratios and treatment duration were determined to assess the association between CNS-active drugs and NDDs at different ages and treatment duration intervals.

RESULTS: In 309,128 patients who met inclusion criteria, exposure to CNS-active drugs was associated with a decreased risk of AD (0.86% vs 1.73%, RR: 0.50; 95% CI: 0.47-0.53; p <.0001) and all NDDs (3.13% vs 5.76%, RR: 0.54; 95% CI: 0.53-0.56; p <.0001). Analysis of impact of drug class on risk of AD indicated that antidepressant, sedative, anticonvulsant, and stimulant medications were associated with significantly reduced risk of AD whereas atypical antipsychotics were associated with increased AD risk. The greatest risk reduction for AD and NDDs occurred in patients aged 70 years or older with a protective effect only in patients with long-term therapy (>3 years). Furthermore, responders to these therapeutics were characterized by diagnosed obesity and higher prescriptions of anti-inflammatory drugs and menopausal hormonal therapy, compared to patients with a diagnosis of AD (non-responders). Addition of a second CNS-active drug was associated with greater reduction in AD risk compared to monotherapy, with the combination of a Z-drug and an SNRI associated with greatest AD risk reduction.

CONCLUSION: Collectively, these findings indicate that CNS-active drugs were associated with reduced risk of developing AD and other age-related NDDs. The exception was atypical antipsychotics, which increased risk. Potential use of combination therapy with atypical antipsychotics could mitigate the risk conferred by these drugs. Evidence from these analyses advance precision prevention strategies to reduce the risk of age-related NDDs in persons with neuropsychiatric disorders.},

abstract = {BACKGROUND: Japanese brome (Bromus japonicus Thumb.) is one of the problematic annual weeds in winter wheat (Triticum aestivum L.) and is generally controlled by acetolactate synthase (ALS) inhibitors. Repeated use of the ALS inhibitor propoxycarbazone-Na resulted in the evolution of resistance to this herbicide in three B. japonicus populations, i.e., R1, R2, and R3 in Kansas (KS). However, the level of resistance and mechanism conferring resistance in these populations is unknown. The objectives of this research were to 1) evaluate the level of resistance to propoxycarbazone-Na in R1, R2, and R3 in comparison with a known susceptible population (S1), 2) investigate the mechanism of resistance involved in conferring ALS-inhibitor resistance, and 3) investigate the cross-resistance to other ALS inhibitors.

RESULTS: Dose-response (0 to 16x; x = 44 g ai ha[-1] of propoxycarbazone-Na) assay indicated 167, 125, and 667- fold resistance in R1, R2 and R3 populations, respectively, compared to S1 population. ALS gene sequencing confirmed the mutations resulting in amino acid substitutions, i.e., Pro-197-Thr (R3, R1)/Ser (R2, R1) bestowing resistance to these ALS inhibitors. Such amino acid substitutions also showed differential cross-resistance to sulfosulfuron, mesosulfuron-methyl, pyroxsulam, and imazamox among resistant populations. Pretreatment with malathion (a cytochrome P450 enzyme-inhibitor) followed by imazamox treatment suggested cross-resistance to this herbicide possibly via metabolism only in R3 population.

CONCLUSION: Overall, these results confirm the first case of target-site based resistance to ALS inhibitors in B. japonicus in the US, highlighting the need for exploring herbicides with alternative modes of action to enhance weed control in winter wheat.},

The window of treatment has significantly increased the number of patients who would benefit from intervention and operators may be confronted with patients harboring preexistent neurological disorders. Still, the epidemiology of patients with AIS and neurological disorders has not been established.

METHODS: This is a retrospective study, which utilizes data from the National Inpatient Sample (NIS) between 2012 and 2016. Patients with the major neurological comorbidities in the study were included: Alzheimer's dementia (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and myasthenia gravis (MG). These patients were divided into groups and analyzed based on discharged home status, length of hospital stay (LOS), and inpatient mortality. These outcomes were also compared between patients who underwent MT versus those who did not.

RESULTS: In this study, 460,070 patients with AIS were identified and included. MT was performed less often when the patient had a neurological diagnosis compared to those without a neurological disease (p<0.0001). However, patients with AIS who have underlying neurological disorders such as AD, PD, and MS have shown similar outcomes after MT to those who do not have these disorders.

CONCLUSION: Patients with preexisting neurological disorders were less likely to undergo MT. Further studies are required to elucidate the implications of having a neurological disorder in the setting of an AIS.},

abstract = {Studies have demonstrated the neuroprotective effect of cannabidiol (CBD) and other Cannabis sativa L. derivatives on diseases of the central nervous system caused by their direct or indirect interaction with endocannabinoid system-related receptors and other molecular targets, such as the 5-HT1A receptor, which is a potential pharmacological target of CBD. Interestingly, CBD binding with the 5-HT1A receptor may be suitable for the treatment of epilepsies, parkinsonian syndromes and amyotrophic lateral sclerosis, in which the 5-HT1A serotonergic receptor plays a key role. The aim of this review was to provide an overview of cannabinoid effects on neurological disorders, such as epilepsy, multiple sclerosis and Parkinson's diseases, and discuss their possible mechanism of action, highlighting interactions with molecular targets and the potential neuroprotective effects of phytocannabinoids. CBD has been shown to have significant therapeutic effects on epilepsy and Parkinson's disease, while nabiximols contribute to a reduction in spasticity and are a frequent option for the treatment of multiple sclerosis. Although there are multiple theories on the therapeutic potential of cannabinoids for neurological disorders, substantially greater progress in the search for strong scientific evidence of their pharmacological effectiveness is needed.},

abstract = {Amyotrophic Lateral Sclerosis (ALS) is a highly fatal neurodegenerative disorder characterized by the progressive wasting and paralysis of voluntary muscle. Despite extensive research, the etiology of ALS remains elusive, and effective treatment options are limited. However, recent evidence implicates gut dysbiosis and gut-brain axis (GBA) dysfunction in ALS pathogenesis. Alterations to the composition and diversity of microbial communities within the gut flora have been consistently observed in ALS patients. These changes are often correlated with disease progression and patient outcome, suggesting that GBA modulation may have therapeutic potential. Indeed, targeting the gut microbiota has been shown to be neuroprotective in several animal models, alleviating motor symptoms and mitigating disease progression. However, the translation of these findings to human patients is challenging due to the complexity of ALS pathology and the varying diversity of gut microbiota. This review comprehensively summarizes the current literature on ALS-related gut dysbiosis, focusing on the implications of GBA dysfunction. It delineates three main mechanisms by which dysbiosis contributes to ALS pathology: compromised intestinal barrier integrity, metabolic dysfunction, and immune dysregulation. It also examines preclinical evidence on the therapeutic potential of gut-microbiota-modulating agents (categorized as prebiotics, probiotics, and postbiotics) in ALS.},

Defining a way to subcluster ALS patients is becoming a central endeavor in the field. Identifying specific clusters and applying them in clinical trials could enable the development of more effective treatments.

Due to elevated oxygen consumption, the high presence of easily oxidizable polyunsaturated fatty acids and the weak antioxidant defenses, the brain is particularly vulnerable to oxidative injury. Uncertainty exists over whether these deficits contribute to the development of NDDs or are solely a consequence of neuronal degeneration. Furthermore, these two pathological hallmarks are linked, and it is known that OS can affect the inflammatory response. In this review, we will overview the last findings about these two pathways in the principal NDDs. Moreover, we will focus more in depth on amyotrophic lateral sclerosis (ALS) to understand how anti-inflammatory and antioxidants drugs have been used for the treatment of this still incurable motor neuron (MN) disease. Finally, we will analyze the principal past and actual clinical trials and the future perspectives in the study of these two pathological mechanisms.},

METHODS: Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was used to assess the effectiveness of interventions for ALS. Two systematic reviewers from Cochrane Response supported the guideline panel. The working group identified a total of 26 research questions, performed systematic reviews, assessed the quality of the available evidence, and made specific recommendations. Expert consensus statements were provided where insufficient evidence was available.

RESULTS: A guideline mapping effort revealed only one other ALS guideline that used GRADE methodology (a National Institute for Health and Care Excellence [NICE] guideline). The available evidence was scarce for many research questions. Of the 26 research questions evaluated, the NICE recommendations could be adapted for 8 questions. Other recommendations required updates of existing systematic reviews or de novo reviews. Recommendations were made on currently available disease-modifying treatments, multidisciplinary care, nutritional and respiratory support, communication aids, psychological support, treatments for common ALS symptoms (e.g., muscle cramps, spasticity, pseudobulbar affect, thick mucus, sialorrhea, pain), and end-of-life management.

CONCLUSIONS: This update of the guideline using GRADE methodology provides a framework for the management of ALS. The treatment landscape is changing rapidly, and further updates will be prepared when additional evidence becomes available.},

Cu[II](atsm) is neuroprotective in mutant SOD1 mouse models of ALS where its activity is ascribed in part to improving availability of essential copper. However, SOD1 mutations cause only ~ 2% of ALS cases and therapeutic relevance of copper availability in sporadic ALS is unresolved. Herein we assessed spinal cord tissue from human cases of sporadic ALS for copper-related changes. We found that when compared to control cases the natural distribution of spinal cord copper was disrupted in sporadic ALS. A standout feature was decreased copper levels in the ventral grey matter, the primary anatomical site of neuronal loss in ALS. Altered expression of genes involved in copper handling indicated disrupted copper availability, and this was evident in decreased copper-dependent ferroxidase activity despite increased abundance of the ferroxidases ceruloplasmin and hephaestin. Mice expressing mutant SOD1 recapitulate salient features of ALS and the unsatiated requirement for copper in these mice is a biochemical target for Cu[II](atsm). Our results from human spinal cord indicate a therapeutic mechanism of action for Cu[II](atsm) involving copper availability may also be pertinent to sporadic cases of ALS.},

abstract = {Candida auris is a fungal pathogen of humans responsible for nosocomial infections with high mortality rates. High levels of resistance to antifungal drugs and environmental persistence mean these infections are difficult to treat and eradicate from a healthcare setting. Understanding the life cycle and the genetics of this fungus underpinning clinically relevant traits, such as antifungal resistance and virulence, is of the utmost importance to develop novel treatments and therapies. Epidemiological and genomic studies have identified five geographical clades (I-V), which display phenotypic and genomic differences. Aggregation of cells, a phenotype primarily of clade III strains, has been linked to reduced virulence in some infection models. The aggregation phenotype has thus been associated with conferring an advantage for (skin) colonisation rather than for systemic infection. However, strains with different clade affiliations were compared to infer the effects of different morphologies on virulence. This makes it difficult to distinguish morphology-dependent causes from clade-specific or even strain-specific genetic factors. Here, we identify two different types of aggregation: one induced by antifungal treatment which is a result of a cell separation defect; and a second which is controlled by growth conditions and only occurs in strains with the ability to aggregate. The latter aggregation type depends on an ALS-family adhesin which is differentially expressed during aggregation in an aggregative C. auris strain. Finally, we demonstrate that macrophages cannot clear aggregates, suggesting that aggregation might after all provide a benefit during systemic infection and could facilitate long-term persistence in the host.},

abstract = {INTRODUCTION: Bromus japonicus is one of the most notorious agricultural weeds in China. The long-term use of ALS-inhibiting herbicides has led to rapid evolution of herbicide resistance in B. japonicus. B. japonicus population (BJ-R) surviving mesosulfuron-methyl treatment was collected from wheatland. Here, we aimed to confirm the resistance mechanisms in this putative resistant population.

METHODS: The dose-reponse tests were used to test the resistance level of the B. japonicus to ALS-inhibiting herbicides. Pretreatment with P450 and GST inhibitors and GST activity assays were used to determine whether P450 or GST was involved in the resistance of the BJ-R population. Sanger sequencing was used to analyse the ALS mutation of the BJ-R population. RT-qPCR was used to confirm the the expression levels of the ALS gene in mesosulfuron-methyl -resistant (BJ-R) and-susceptible (BJ-S) B. japonicus. An in vitro ALS activity assay was used to determine the ALS activity of the BJ-R and BJ-S populations. Homology modelling and docking were used to determine the binding energy of the BJ-R and BJ-S populations with ALS-inhibiting herbicides.

RESULTS: B. japonicus population (BJ-R) was confirmed to be 454- and 2.7-fold resistant to the SU herbicides mesosulfuron-methyl and nicosulfuron, and 7.3-, 2.3-, 1.1- and 10.8-fold resistant to the IMI herbicide imazamox, the TP herbicide penoxsulam, the PTB herbicide pyribenzoxim and the SCT herbicide flucarbazone-sodium, respectively, compared with its susceptible counterpart (BJ-S). Neither a P450 inhibitor nor a GST inhibitor could reverse the level of resistance to mesosulfuron-methyl in BJ-R. In addition, no significant differences in GST activity were found between the BJ-R and BJ-S. ALS gene sequencing revealed a Pro-197-Thr mutation in BJ-R, and the gene expression had no significant differences between the BJ-R and BJ-S. The ALS activity of BJ-R was 106-fold more tolerant to mesosulfuron-methyl than that of BJ-S. Molecular docking showed that the binding energy of the ALS active site and mesosulfuron-methyl was changed from -6.67 to -4.57 kcal mol[-1] due to the mutation at position 197.

DISCUSSION: These results suggested that the Pro-197-Thr mutation was the main reason for the high resistance level of BJ-R to mesosulfuron-methyl. Unlike previous reports of the cross-resistance pattern conferred by this mutation, we firstly documented that the Pro-197-Thr mutation confers broad cross-resistance spectrums to ALS-inhibiting herbicides in B. japonicus.},

The diagnosis and treatment of ALS are inherently challenging due to its complex pathomechanism. Long noncoding RNAs (lncRNAs) are transcripts longer than 200 nucleotides involved in different cellular processes, incisively gene expression. In recent years, more studies have been conducted on lncRNA classes and interference in different disease pathologies, showing their promising contribution to diagnosing and treating neurodegenerative diseases. In this review, we discussed the role of lncRNAs like NEAT1 and C9orf72-as in ALS pathogenesis mechanisms caused by mutations in different genes, including TAR DNA-binding protein-43 (TDP-43), fused in sarcoma (FUS), superoxide dismutase type 1 (SOD1). NEAT1 is a well-established lncRNA in ALS pathogenesis; hence, we elaborate on its involvement in forming paraspeckles, stress response, inflammatory response, and apoptosis. Furthermore, antisense lncRNAs (as-lncRNAs), a key group of transcripts from the opposite strand of genes, including ZEB1-AS1 and ATXN2-AS, are discussed as newly identified components in the pathology of ALS. Ultimately, we review the current standing of using lncRNAs as biomarkers and therapeutic agents and the future vision of further studies on lncRNA applications.},

Considerable evidence indicates that early skeletal muscle atrophy plays a crucial role in the disease pathogenesis, leading to an altered muscle-motor neuron crosstalk that, in turn, may contribute to motor neuron degeneration. Currently, there is no effective treatment for ALS, highlighting the need to dig deeper into the pathological mechanisms for developing innovative therapeutic strategies. FM19G11 is a novel drug able to modulate the global cellular metabolism, but its effects on ALS skeletal muscle atrophy and mitochondrial metabolism have never been evaluated, yet. This study investigated whether FM19G11-loaded nanoparticles (NPs) may affect the bioenergetic status in myoblasts isolated from G93A-SOD1 mice at different disease stages. We found that FM19G1-loaded NP treatment was able to increase transcriptional levels of Akt1, Akt3, Mef2a, Mef2c and Ucp2, which are key genes associated with cell proliferation (Akt1, Akt3), muscle differentiation (Mef2c), and mitochondrial activity (Ucp2), in G93A-SOD1 myoblasts. These cells also showed a significant reduction of mitochondrial area and networks, in addition to decreased ROS production after treatment with FM19G11-loaded NPs, suggesting a ROS clearance upon the amelioration of mitochondrial dynamics. Our overall findings demonstrate a significant impact of FM19G11-loaded NPs on muscle cell function and bioenergetic status in G93A-SOD1 myoblasts, thus promising to open new avenues towards possible adoption of FM19G11-based nanotherapies to slow muscle degeneration in the frame of ALS and muscle disorders.},

Exosomes are nanometer-sized vesicles that released by Schwann cells may have neuroprotective effects by reducing posttraumatic inflammatory processes as well as promoting tissue healing and functional recovery. The purpose of this study was to evaluate the beneficial effects of human Schwann-cell exosomes (hSC-Exos) in a severe model of penetrating ballistic-like brain injury (PBBI) in rats and investigate effects on multiple outcomes. Human Schwann cell processing protocols followed Current Good Manufacturing Practices (cGMP) with exosome extraction and purification steps approved by the FDA for an expanded access single ALS patient IND. Anesthetized male Sprague-Dawley rats (280-350g) underwent PBBI surgery or sham procedures and starting 30 min after injury received either a dose of hSC-Exos or PBS through the jugular vein. At 48hrs after PBBI, flow cytometry analysis of cortical tissue revealed that hSC-Exos administration reduced the number of activated microglia and levels of caspase-1, a marker of inflammasome activation. Neuropathological analysis at 21 days showed that hSC-Exos treatment after PBBI significantly reduced overall contusion volume and decreased the frequency of Iba-1 positive activated and amoeboid microglia by immunocytochemical analysis. This study revealed that the systemic administration of hSC-Exos is neuroprotective in a model of severe TBI and reduces secondary inflammatory injury mechanisms and histopathological damage. The administration of hSC-Exos represents a clinically relevant cell-based therapy to limit the detrimental effects of neurotrauma or other progressive neurological injuries by impacting multiple pathophysiological events and promoting neurological recovery.},

abstract = {BACKGROUND: There is a lack of effective therapeutic strategies for amyotrophic lateral sclerosis (ALS); therefore, drug repurposing might provide a rapid approach to meet the urgent need for treatment.

METHODS: To identify therapeutic targets associated with ALS, we conducted Mendelian randomization (MR) analysis and colocalization analysis using cis-eQTL of druggable gene and ALS GWAS data collections to determine annotated druggable gene targets that exhibited significant associations with ALS. By subsequent repurposing drug discovery coupled with inclusion criteria selection, we identified several drug candidates corresponding to their druggable gene targets that have been genetically validated. The pharmacological assays were then conducted to further assess the efficacy of genetics-supported repurposed drugs for potential ALS therapy in various cellular models.

RESULTS: Through MR analysis, we identified potential ALS druggable genes in the blood, including TBK1 [OR 1.30, 95%CI (1.19, 1.42)], TNFSF12 [OR 1.36, 95%CI (1.19, 1.56)], GPX3 [OR 1.28, 95%CI (1.15, 1.43)], TNFSF13 [OR 0.45, 95%CI (0.32, 0.64)], and CD68 [OR 0.38, 95%CI (0.24, 0.58)]. Additionally, we identified potential ALS druggable genes in the brain, including RESP18 [OR 1.11, 95%CI (1.07, 1.16)], GPX3 [OR 0.57, 95%CI (0.48, 0.68)], GDF9 [OR 0.77, 95%CI (0.67, 0.88)], and PTPRN [OR 0.17, 95%CI (0.08, 0.34)]. Among them, TBK1, TNFSF12, RESP18, and GPX3 were confirmed in further colocalization analysis. We identified five drugs with repurposing opportunities targeting TBK1, TNFSF12, and GPX3, namely fostamatinib (R788), amlexanox (AMX), BIIB-023, RG-7212, and glutathione as potential repurposing drugs. R788 and AMX were prioritized due to their genetic supports, safety profiles, and cost-effectiveness evaluation. Further pharmacological analysis revealed that R788 and AMX mitigated neuroinflammation in ALS cell models characterized by overly active cGAS/STING signaling that was induced by MSA-2 or ALS-related toxic proteins (TDP-43 and SOD1), through the inhibition of TBK1 phosphorylation.

CONCLUSIONS: Our MR analyses provided genetic evidence supporting TBK1, TNFSF12, RESP18, and GPX3 as druggable genes for ALS treatment. Among the drug candidates targeting the above genes with repurposing opportunities, FDA-approved drug-R788 and AMX served as effective TBK1 inhibitors. The subsequent pharmacological studies validated the potential of R788 and AMX for treating specific ALS subtypes through the inhibition of TBK1 phosphorylation.},

However, delivery to extrahepatic tissues like the CNS has been a bottleneck in the clinical development of RNAi. Herein, we identify potent siRNA duplexes for the knockdown of human SOD1 in which medicinal chemistry and conjugation to an accessory oligonucleotide (ACO) enable activity in CNS tissues. Local delivery via intracerebroventricular or intrathecal injection into SOD1[G93A] mice delayed disease progression and extended animal survival with superior efficacy compared with an ASO resembling tofersen in sequence and chemistry. Treatment also prevented disease-related declines in motor function, including improvements in animal mobility, muscle strength, and coordination. The ACO itself does not target any specific complementary nucleic acid sequence; rather, it imparts benefits conducive to bioavailability and delivery through its chemistry. The complete conjugate (i.e., siRNA-ACO) represents a novel modality for delivery of duplex RNA (e.g., siRNA) to the CNS that is currently being tested in the clinic for treatment of ALS.},

Due to the lack of trunk neuromuscular organoids (NMOs) from ALS patients' induced pluripotent stem cells (iPSCs), an organoid system was missing to model the trunk spinal neuromuscular neurodegeneration. With the C9orf72 ALS patient-derived iPSCs and isogenic controls, we used an NMO system containing trunk spinal cord neural and peripheral muscular tissues to show that the ALS NMOs could model peripheral defects in ALS, including contraction weakness, neural denervation, and loss of Schwann cells. The neurons and astrocytes in ALS NMOs manifested the RNA foci and dipeptide repeat proteins. Acute treatment with the unfolded protein response inhibitor GSK2606414 increased the glutamatergic muscular contraction 2-fold and reduced the dipeptide repeat protein aggregation and autophagy. This study provides an organoid system for spinal neuromuscular pathologies in ALS and its application for drug testing.},

abstract = {OBJECTIVE: The aim of this clinical study is to obtain evidence for the clinical efficacy of Bu-Shen-Jian-Pi formula (BSJP), a traditional Chinese medicine, used for the treatment of amyotrophic lateral sclerosis, a relatively rare, progressive and usually fatal disease possibly associated with alterations in tissue redox status, hypoxia, and muscular injury.

BACKGROUND: The active agents in BSJP formula† causing apoptosis, modulation of redox changes, and alterations in the immune status have been studied previously by us using cell cultures. The findings from these investigations have been incorporated into pharmacology databases employed in our analysis of BSJP using network pharmacology analysis/artifical intelligence. This information has been used here in the design of the investigation and to optimize evaluation of the clinical efficacy and usefulness of this herbal medicine, as far as possible using evidence-based medicine criteria.

MATERIALS AND METHODS: The design of the study was a randomized multi-center, controlled clinical trial in 127 patients with confirmed diagnoses of amyotrophic lateral sclerosis. Patients and investigator were double-blinded. Clinical efficacy was determined using the Amyotrophic Lateral Sclerosis Symptom Score in Integrative Treatment Scale (ALS-SSIT) and the Amyotrophic Lateral Sclerosis Rating Scale-Revised (ALSFRS-R), together with tests of limb muscle strength using the manual muscle test (MMT), forced vital capacity (FVC), and clinical chemistry laboratory tests over a 20-week observation period.

RESULTS: The scores of ALS-SSIT in the BSJP group increased significantly (22%) after treatment. The ALSFRS-R score in the BSJP group decreased significantly after treatment (19%). The rate of decrease in muscle function (MMT score) in most BSJP patients was lower than that in the control group, where the differences in the scores for the trapezius and triceps brachii were statistically significant compared to the control group. The fall in FVC in the BJSP group was significantly slower than in the control group. There were no marked differences observed in the frequency of side effects. Serum vitamin D3 levels in the BSJP group showed greater increases compared to the control group.

CONCLUSION: BSJP treatment reduced the rate of progression of amyotrophic lateral sclerosis according to the ALS-SSITS and ALSFRS scores and significantly reduced the rate of deterioration in muscle function in the limbs of amyotrophic lateral sclerosis patients. The modes of action of BSJP in treating amyotrophic lateral sclerosis are probably diverse and multi targeted, some of which may involve regulation of serum vitamin D3 and alleviation of the impairments in liver and kidney function.},

MATERIALS AND METHODS: Mitochondrial protection activity was determined using a hypoxia-reoxygenation in vitro model based on the neuroblastoma cell line SH-SY5Y and measurements of anti-ferroptotic activity.

RESULTS: Icariin, naringenin, kaempferol, and formononetin showed mitochondrial protective activity involving diverse signaling pathways. The cytoprotective effects of formononetin depended on the inhibition of ferroptosis. Hypoxia-reoxygenation stimulation induced ferroptosis in SH-SY5Y cells.

DISCUSSION: Ferroptosis is a key mechanism in nervous system diseases and is associated with hypoxia-reoxygenation injury. Naringenin and kaempferol were devoid of anti-ferroptotic activity.

CONCLUSION: Evidence has been obtained showing that the core components: icariin, naringenin, kaempferol, and formononetin in BSJP formula have anti-hypoxic and mitochondrial protective activity of potential clinical importance in the treatment of amyotrophic lateral sclerosis and patients with symptoms of hypoxia.},

abstract = {Spinocerebellar ataxia type 3 (SCA3) is the most common dominantly inherited ataxia. Currently, no preventative or disease-modifying treatments exist for this progressive neurodegenerative disorder, although efforts using gene silencing approaches are under clinical trial investigation. The disease is caused by a CAG repeat expansion in the mutant gene, ATXN3, producing an enlarged polyglutamine tract in the mutant protein. Similar to other paradigmatic neurodegenerative diseases, studies evaluating the pathogenic mechanism focus primarily on neuronal implications. Consequently, therapeutic interventions often overlook non-neuronal contributions to disease. Our lab recently reported that oligodendrocytes display some of the earliest and most progressive dysfunction in SCA3 mice. Evidence of disease-associated oligodendrocyte signatures has also been reported in other neurodegenerative diseases, including Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, and Huntington's disease. Here, we assess the effects of anti-ATXN3 antisense oligonucleotide (ASO) treatment on oligodendrocyte dysfunction in premanifest and symptomatic SCA3 mice. We report a severe, but modifiable, deficit in oligodendrocyte maturation caused by the toxic gain-of-function of mutant ATXN3 early in SCA3 disease that is transcriptionally, biochemically, and functionally rescued with anti-ATXN3 ASO. Our results highlight the promising use of an ASO therapy across neurodegenerative diseases that requires glial targeting in addition to affected neuronal populations.},

abstract = {RATIONALE: Amyotrophic lateral sclerosis (ALS) poses a significant clinical challenge due to its rapid progression and limited treatment options, often leading to deadly outcomes. Looking for effective therapeutic interventions is critical to improve patient outcomes in ALS.

PATIENT CONCERNS: The patient, a 75-year-old East Asian male, manifested an insidious onset of right-hand weakness advancing with dysarthria. Comprehensive Next-generation sequencing analysis identified variants in specific genes consistent with ALS diagnosis.

DIAGNOSES: ALS diagnosis is based on El Escorial diagnostic criteria.

INTERVENTIONS: This study introduces a novel therapeutic approach using artificial intelligence phenotypic response surface (AI-PRS) technology to customize personalized drug-dose combinations for ALS. The patient underwent a series of phases of AI-PRS-assisted trials, initially incorporating a 4-drug combination of Ibudilast, Riluzole, Tamoxifen, and Ropinirole. Biomarkers and regular clinical assessments, including nerve conduction velocity, F-wave, H-reflex, electromyography, and motor unit action potential, were monitored to comprehensively evaluate treatment efficacy.

OUTCOMES: Neurophysiological assessments supported the ALS diagnosis and revealed the co-presence of diabetic polyneuropathy. Hypotension during the trial necessitated an adaptation to a 2-drug combinational trial (ibudilast and riluzole). Disease progression assessment shifted exclusively to clinical tests of muscle strength, aligning with the patient's well-being.

LESSONS: The study raises the significance of personalized therapeutic strategies in ALS by AI-PRS. It also emphasizes the adaptability of interventions based on patient-specific responses. The encountered hypotension incident highlights the importance of attentive monitoring and personalized adjustments in treatment plans. The described therapy using AI-PRS, offering personalized drug-dose combinations technology is a potential approach in treating ALS. The promising outcomes warrant further evaluation in clinical trials for searching a personalized, more effective combinational treatment for ALS patients.},

abstract = {In the recent past, there has been an ever-increasing interest in the search for metal-based therapeutic drug candidates for protein misfolding disorders (PMDs) particularly neurodegenerative disorders such as Alzheimer's, Parkinson's, Prion's diseases, and amyotrophic lateral sclerosis. Also, different amyloidogenic variants of human lysozyme (HL) are involved in hereditary systemic amyloidosis. Metallo-therapeutic agents are extensively studied as antitumor agents, however, they are relatively unexplored for the treatment of non-neuropathic amyloidoses. In this work, inhibition potential of a novel ionic cobalt(II) therapeutic agent (CoTA) of the formulation [Co(phen)(H2O)4][+][glycinate][-] is evaluated against HL fibrillation. Various biophysical techniques viz., dye-binding assays, dynamic light scattering (DLS), differential scanning calorimetry (DSC), electron microscopy, and molecular docking experiments validate the proposed mechanism of inhibition of HL fibrillation by CoTA. The experimental corroborative results of these studies reveal that CoTA can suppress and slow down HL fibrillation at physiological temperature and pH. DLS and 1-anilino-8-naphthalenesulfonate (ANS) assay show that reduced fibrillation in the presence of CoTA is marked by a significant decrease in the size and hydrophobicity of the aggregates. Fluorescence quenching and molecular docking results demonstrate that CoTA binds moderately to the aggregation-prone region of HL (Kb = 6.6 × 10[4] M[-1]), thereby, inhibiting HL fibrillation. In addition, far-UV CD and DSC show that binding of CoTA to HL does not cause any change in the stability of HL. More importantly, CoTA attenuates membrane damaging effects of HL aggregates against RBCs. This study identifies inorganic metal complexes as a therapeutic intervention for systemic amyloidosis.},

The objective of this scoping review was to synthesize what is known about the impact of smoking and smoking cessation on disease-specific outcomes for seven common neurological disorders. We included 67 studies on the association of smoking and smoking cessation on disease-specific outcomes. For multiple sclerosis, smoking was associated with greater clinical and radiological disease progression, relapses, risk for disease-related death, cognitive decline, and mood symptoms, in addition to reduced treatment effectiveness. For stroke and transient ischemic attack, smoking was associated with greater rates of stroke recurrence, post-stroke cardiovascular outcomes, post-stroke mortality, post-stroke cognitive impairment, and functional impairment. In patients with cognitive impairment and dementia, smoking was associated with faster cognitive decline, and smoking was also associated with greater cognitive decline in Parkinson's disease, but not motor symptom worsening. Patients with amyotrophic lateral sclerosis who smoked faced increased mortality. Last, in patients with cluster headache, smoking was associated with more frequent and longer cluster attack periods. Conversely, for multiple sclerosis and stroke, smoking cessation was associated with improved disease-specific outcomes. In summary, whereas smoking is detrimentally associated with disease-specific outcomes in common neurological conditions, there is growing evidence that smoking cessation may improve outcomes. Effective smoking cessation interventions should be leveraged in the management of common neurological disorders to improve patient outcomes.},

abstract = {OBJECTIVE: Dural arteriovenous fistulas are rare vascular malformations that affect the brain and spinal cord. Spinal dural arteriovenous fistulas (sdAVFs) are the most frequently encountered vascular malformation affecting the spinal cord. The object of this study was to evaluate the impact of treatment delays on the long-term neurological outcomes of either open surgical or interventional treatment of sdAVFs.

METHODS: In this retrospective, population-based cohort study, the authors examined consecutive patients with diagnosed sdAVFs at a tertiary care center between 2005 and 2020. Patients were assessed using the Aminoff-Logue disability scale (ALS) at various time points including symptom onset, primary care visit, first specialist outpatient visit, as well as both short and long-term follow-ups. The postoperative long-term ALS gait and bladder grades constituted the primary outcomes of the study.

RESULTS: Among the 34 patients included in the study, the median age was 65 years, and there was a male predominance (71%). Most lesions were in the lumbar region (47%). Significant worsening in ALS gait and bladder grades was observed preoperatively, followed by postoperative improvements (p < 0.05). There was no difference in outcomes between surgical and endovascular treatments. Older age (OR 1.10, 95% CI 1.03-1.17, p = 0.007), worse preoperative ALS gait grades (OR 5.12, 95% CI 2.18-12.4, p < 0.001), and longer time from first specialist outpatient visit to first treatment (OR 1.00, 95% CI 1.00-1.01, p = 0.040) were independently associated with worse long-term gait outcomes. Only the preoperative ALS bladder score was a predictor of worse long-term bladder function (OR 92.7, 95% CI 28.0-306.7, p < 0.001).

CONCLUSIONS: Both surgical and endovascular treatments for sdAVFs led to significant neurological improvements. However, treatment delays were associated with less favorable long-term outcomes. Prompt diagnosis and early intervention prior to symptom progression may enhance recovery and help to preserve neurological function.},
