Abstract
En 中文
• Sarcopenia affects over half of community-dwelling adults aged ≥80 years. • R. lactatiformans and P. faecium are novel gut biomarkers for sarcopenia. • Microbiota functional dysregulation includes altered purine and biotin metabolism. • R. lactatiformans abundance correlates negatively with dietary maltose intake.
