Gastrointestinal Health

This hub offers a comprehensive resource on gastrointestinal health, digestive diseases, and the human microbiome, drawing together authoritative articles on basic science, clinical management, and emerging research. The collection addresses the pathophysiology, diagnosis, and treatment of major gastrointestinal disorders, including irritable bowel syndrome, celiac disease, inflammatory bowel disease, and gastroesophageal reflux, while also exploring surgical, dietary, and pharmacological interventions. Special emphasis is given to the role of the gut microbiome in health and disease, including its influence on immunity, metabolism, neurological function, and response to therapy. Readers will also find up-to-date insights into microbiome-related interventions, such as fecal microbiota transplantation, as well as practical guidance for dietary management and prevention. This hub serves as a trusted reference for clinicians, researchers, and individuals seeking an evidence-based understanding of digestive and microbiome science.

Yale study offers critical clues for future norovirus treatments

As the leading cause of viral gastroenteritis worldwide, norovirus is an all too familiar ailment. Its telltale digestive upset — not to mention its reputation for being notoriously contagious — has earned it the nicknames "winter vomiting bug" and "stomach flu."

Gut microbes emerge as potential players in estrogen-driven cancers

A new review maps how the endocrine-microbiome axis expands the estrobolome concept, showing that gut microbes may alter estrogen recycling, produce hormone-like metabolites, and shape inflammation and tissue environments in hormone-driven cancers. Human evidence remains mostly associative, so the authors call for causal models, longitudinal multi-omics, multi-kingdom profiling, and sex-stratified studies before microbiome-guided cancer strategies enter routine care.

Blood metabolites reveal lifestyle links to brain health before dementia

Blood metabolome profiling in dementia-free middle-aged adults linked 14 metabolites to cognition and 22 metabolites to MRI markers of brain health. Lifestyle, clinical factors, medication use and gut microbiota appeared to shape many of these metabolites, with ergothioneine emerging as a notable cognition-linked signal.
