Introduction Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease with poorly understood pathophysiology. Recent studies have highlighted systemic inflammation, especially the role of circulating inflammatory proteins, in ALS. Methods This study investigates potential causal link between these proteins and We employed two-sample Mendelian Randomization(MR) approach, analyzing data from large-scale genome-wide association to explore relationship 91 included various MR methods like Egger, weighted median, inverse-variance weighted, complemented by sensitivity analyses for robust results. Results Significant associations were observed levels including Adenosine Deaminase, Interleukin-17C, Oncostatin-M, Leukemia Inhibitory Factor Receptor, Osteoprotegerin, ALS risk. Consistencies noted across different P -value thresholds. Bidirectional suggested that risk might influence certain proteins.

Currently, sleep disorders (SD) in the elderly are gaining prominence globally and becoming a significant public health concern. Methyl donor nutrients (MDNs), such as vitamin B6, B12, folate, choline, have been reported to potential improve disorders. Moreover, MDNs help maintain gut flora homeostasis, closely associated with development of SD. Nevertheless, there has lack comprehensive human studies examining association between intake In our study, we comprehensively evaluated SD used 16S rRNA gene sequencing explore underlying mechanism. We found that group (n = 91) had lower methyl-donor nutritional quality index (MNQI) trend toward compared control 147). Based on intestinal microbiome, beta diversity was higher high (HQ) low (LQ) group, it group. This suggests may regulate by modulating abundance distribution microbiota. Subsequently, performed correlation analyses relative microbiota, intake, Pittsburgh Sleep Quality Index (PSQI), identifying five genera regulatory roles. The KEGG pathway analysis indicated energy metabolism one-carbon might be pathways through which modulate sleep. study offers dietary guidance strategies for managing provides insights targeted microbiota intervention.
