To examine the personal significance or clinical concerns among different individuals associated with having various gastrointestinal symptoms, as reflected in self-reported bothersomeness, life interference and potential for needing medical attention for those symptoms. Also to evaluate associated factors such as the symptom-related quality of life effects and impact on psychological wellbeing.

The study intends to assess the effectiveness of a board exam curricula for a group of gastroenterology fellows. The study aims to assess how prepared this curricula makes the gastroenterology fellows feel, as well as objective impact on in-training exam scores.

For adults undergoing a standard of care biopsy for screening or surveillance of Barrett's Esophagus (BE). We are comparing two biopsy methods: Seattle biopsy versus WATS biopsy for the detection of intestinal metaplasia (change in the lining of your esophagus or 'food tube' to that of your stomach).

To learn if one kind of treatment approach, either (1) endoscopic surveillance or (2) endoscopic eradication therapy, is better, the same, or worse for treating patients with Barrett's esophagus and low-grade dysplasia.

we propose the creation of a prospective multi-center registry of patients with IBD and EIM, initially focusing on peripheral arthritis, the most common and understudied EIM, to better understand clinical course and management.

To create a multi-centered prospective registry of individuals ≥60 years ("older adults") with IBD to quantify prevalence, incidence and progression of frailty, multi-morbidity, physical and cognitive impairment

The primary objective for this registry is to prospectively study the natural history of IBD, the prevalence and incidence of comorbidities, and targeted adverse events, as well as the utilization patterns and the comparative effectiveness and comparative safety of approved IBD treatments.

To assess hepatitis C virus treatment and hepatocellular carcinoma surveillance within practices and gauge the feasibility of a program to implement point-of-care risk stratification tools and screening referral systems.

The study is designed to look at Crohn's disease over a period time, from before a surgery to 12 months after the surgery has taken place. The role bacteria in the gut plays in Crohn's disease (CD) is not well understood. Which particular microbes contribute to disease remain unknown. In CD, ~70% of patients will end up requiring surgery due to chronic unrelenting complications, and ~50% require additional surgery. We hope to identify key microbes at the time of surgery in stool and tissue and correlate it over time with data collected at timepoints after surgery. We will use this data with clinical information to determine if specific microbes are associated with disease recurrence.

The purpose of this research study is to learn more about Barrett's Esophagus and esophageal cancer by collecting data and samples (blood and tissue) for a biorepository. A biorepository is a large bank of specimens and data that are stored indefinitely and may be shared with other researchers.
