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.

Pneumococcal vaccination lowers antibiotic-resistant bacteria in children

Children in Guatemala who received a common vaccine that helps prevent pneumonia were less likely to carry antibiotic-resistant bacteria, according to a new study led by Washington State University researchers.

Asian IBD patients show lower PSC prevalence and better clinical outcomes

Primary sclerosing cholangitis (PSC) is a chronic, progressive inflammatory disease characterized by fibrosis and bile duct stricturing, which ultimately leads to cirrhosis and liver failure. PSC is strongly associated with both types of inflammatory bowel disease (IBD), namely, ulcerative colitis and Crohn's disease.

International collaboration develops STREAMS to standardize microbiome data

Microbiomes, the communities of microorganisms that live in and around us, play a vital role in everything from human health to soil fertility and climate regulation. But studying these tiny life forms, especially outside the human body, presents a major challenge: how do scientists share complex data across such a wide range of environments and disciplines?
