Observational Study
Western Dietary Pattern Increases, and Prudent Dietary Pattern Decreases, Risk of Incident Diverticulitis in a Prospective Cohort Study.
Dietary fiber is implicated as a risk factor for diverticulitis. Analyses of dietary patterns may provide information on risk beyond those of individual foods or nutrients. We examined whether major dietary patterns are associated with risk of incident diverticulitis. ⋯ In a prospective cohort study of 46,295 men, a Western dietary pattern was associated with increased risk of diverticulitis, and a prudent pattern was associated with decreased risk. These data can guide dietary interventions for the prevention of diverticulitis.

Concurrent to development of more effective drugs for treatment of hepatitis C virus (HCV) infection, there has been an increase in the incidence of nonalcoholic fatty liver disease. Data indicate that liver transplantation prolongs survival times of patient with acute hepatitis associated with alcoholic liver disease (ALD). We compared data on disease prevalence in the population with data from liver transplantation waitlists to evaluate changes in the burden of liver disease in the United States. ⋯ In an analysis of 3 different databases (National Health and Nutrition Examination Survey, HealthCore, and United Network for Organ Sharing), we found the proportion of patients on the liver transplant waitlist or undergoing liver transplantation for chronic HCV infection to be decreasing and fewer patients to have cirrhosis or CLF. However, the percentages of patients on the waitlist or receiving liver transplants for NASH or ALD are increasing, despite different relative burdens of disease among the entire population of patients with cirrhosis.

Direct oral anticoagulant (DOAC) agents increase the risk of gastrointestinal (GI) bleeding. We investigated which DOAC had the most favorable GI safety profile and compared differences among these drugs in age-related risk of GI bleeding. ⋯ In a population-based study of patients receiving DOAC agents, we found apixaban had the most favorable GI safety profile and rivaroxaban the least favorable profile. GI bleeding events among patient aged 75 years or older taking DOACs increased with age; the risk was greatest among persons 75 years. Apixaban had the most favorable GI safety profile among all age groups.

Many patients with a < 1 cm segment of columnar metaplasia in the distal esophagus, also called an irregular Z line, are encountered. These patients, often referred to as patients with Barrett's esophagus (BE), are enrolled in surveillance programs. However, little is known about their risk of high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC). We aimed to determine the incidence of HGD and EAC in patients with irregular Z line with intestinal metaplasia. ⋯ In a prospective, multicenter cohort study, we found that patients with irregular Z line do not develop HGD or esophageal cancer within 5 years after index endoscopy.
