Evidence on probiotics and prebiotics by indication
American Gastroenterological Association (AGA) Clinical Practice Guidelines on the Role of Probiotics in the Management of Gastrointestinal Disorders
To create these clinical practice guidelines, the AGA reviewed evidence for probiotics and several gastrointestinal disorders. See here for their conclusions. The AGA recommended certain probiotics to prevent necrotizing enterocolitis (NEC) and C. difficile infection, suggesting that all hospital formularies should stock at least one appropriately tested probiotic for these purposes. Further, all physicians should consider recommending appropriately tested probiotics to patients for whom they prescribe antibiotics. The AGA did not consider evidence for probiotics and antibiotic-associated diarrhea. For further explanation, see this blog post: ISAPP take-home points from American Gastroenterological Association guidelines on probiotic use for gastrointestinal disorders.

May 2019 Gut Microbiota for Health World Summit: Session Recordings
These recordings cover the sessions of a recent scientific conference focused on gut microbiota, diet, and health. The recordings are freely accessible but require a login. Available through March 2021. Learning objectives for the conference are as follows:
- Understand the role of diet-microbiota interactions underlying human health and disease.
- Describe current evidence regarding dietary components (such as dietary fiber and fermented foods) and exercise and their influence on the human gut microbiome.
- Describe current understanding of metabolites produced by the gut microbiome and their link to human health and disease.
- Apply current understanding of probiotics for the management of adult and pediatric gastrointestinal disorders to clinical practice.
