In this study, we utilized high-resolution ultrasound to measure VN cross-sectional area (CSA) 96 healthy controls (HCs) 75 PD patients. group was further categorized into three subgroups: PD-preRBD, PD-postRBD, PD-nonRBD.

Abstract This study investigates the differences in gut microbiota composition between DMD patients with (DMD +) and without −) intellectual disability (ID) its potential role cognitive outcomes. In this study, we assessed 50 genetically confirmed (median age 13.1 years) using 16S rRNA gene sequencing. Cognitive assessment was performed Wechsler Intelligence Scales, ID defined as an IQ < 70. Stool samples were analyzed, statistical methods used to assess alpha- beta-diversity. Thirty-four percent of had ID. No significant found alpha-diversity or Firmicutes/Bacteroidetes ratio. However, beta-diversity analysis revealed + − groups, including, , increased abundance Propionibacterium Bifidobacterium a reduction Bulleidia . These bacteria are involved metabolic pathways that can influence neurological health through gut-brain axis, particularly via production short-chain fatty acids. While these preliminary findings suggest possible association profile impairment DMD, further research is needed explore causal relationship consider microbiota-targeted therapeutic strategies.

Parkinson’s disease has long been considered a disorder that primarily affects the brain, as it is defined by dopaminergic neurodegeneration in substantia nigra and brain accumulation of Lewy bodies containing α-synuclein protein. In recent decades, however, accumulating research revealed also involves gut uncovered an intimate important bidirectional link between gut, called “gut–brain axis.” Numerous clinical studies demonstrate dysfunction frequently precedes motor symptoms patients, with findings including impaired intestinal permeability, heightened inflammation, distinct microbiome profiles metabolites. Furthermore, deposition consistently observed suggesting potential role initiation. Importantly, individuals vagotomy have reduced risk. From these observations, researchers hypothesized may initiate subsequently propagate to central neurons through gut–brain axis, leading disease. This review comprehensively examines gut’s involvement disease, focusing on concept gut-origin for We examine interplay altered gut-related factors pathological patients. Given accessibility both dietary pharmacological interventions, targeting gut-localized represents promising avenue developing effective therapies.

Abstract Background Heterozygous variants in GBA1 are the commonest genetic risk factor for Parkinson disease (PD) but penetrance is incomplete. dysfunction can cause gastrointestinal disturbances and microbiome changes preclinical models. Mounting evidence suggests that microbiota-gut-brain axis potentially implicated PD pathogenesis. Whether gut composition influenced by host genetics heterozygosis has never been explored. Objectives To evaluate whether heterozygosity pathogenic L444P variant perturbations composition. Methods Faecal samples collected from L444P/WT WT/WT mice at 3 6 months of age were analysed through shotgun metagenomic sequencing. Results No differences α- β-diversity detected between genotyped groups, either time points. Overall, we found a little variation functional potential over time. Conclusion Host genotype does not impact structure presented mouse model. Studies investigating effect second hit on physiology could explain partial PD.
