Type 1 diabetes (T1D) is a complex disease triggered by a combination of genetic and environmental factors, where abnormal autoimmune responses lead to progressive damage of the pancreatic β cells and severe glucose metabolism disorder. Recent studies have increasingly highlighted the close link between gut microbiota dysbiosis and the development of T1D. This review delves into existing population studies to explore the intricate interactions between the gut microbiota and the immune and metabolic homeostasis in T1D. It summarizes how changes in the structure and function of the gut microbiota are closely associated with the onset and progression of T1D across its natural course and clinical stages. More importantly, based on evidence accumulated from clinical observations and trials, we pioneer the discussion on gut microbiota-based T1D prevention and treatment strategies, this not only enriches our understanding of the complex pathological mechanisms of T1D but also provides potential directions for developing novel prevention and treatment strategies.

Background: Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based practice that can identify adolescents who use alcohol and other drugs and support proper referral to treatment. Despite an American College of Surgeons mandate to deliver SBIRT in pediatric trauma care, trauma centers throughout the United States have faced numerous patient, provider, and organizational level barriers to SBIRT implementation. The Implementing Alcohol Misuse Screening, Brief Intervention, and Referral to Treatment Study (IAMSBIRT) aimed to implement SBIRT across 10 pediatric trauma centers using the Science-to-Service Laboratory (SSL), an empirically supported implementation strategy.

Gastrointestinal (GI) involvement in Lewy body diseases (LBDs) has been observed since the initial descriptions of patients by James Parkinson. Recent experimental and human observational studies raise the possibility that pathogenic alpha-synuclein (⍺-syn) might develop in the GI tract and subsequently spread to susceptible brain regions. The cellular and mechanistic origins of ⍺-syn propagation in disease are under intense investigation.
