Studies found gut microbiome changes linked to Parkinson’s risk before symptoms and hair mineral differences in diagnosed patients. Both findings need larger follow-up studies.
CRS3123, an investigational antibiotic for C. difficile infection, demonstrated 97% clinical cure rates and significantly lower recurrence (4% vs 23% for vancomycin) in a Phase 2 trial.
