Adult-Attained Height and Colorectal Cancer Risk: A Cohort Study, Systematic Review, and Meta-Analysis.

Background: The influence of anthropometric characteristics on colorectal neoplasia biology is unclear. We conducted a systematic review and meta-analysis to determine if adult-attained height is independently associated with the risk of colorectal cancer or adenoma.

Methods: We searched MEDLINE, EMBASE, the Cochrane Library, and Web of Science from inception to August 2020 for studies on the association between adult-attained height and colorectal cancer or adenoma.

Self-reported Metabolic Risk Factor Associations with Adenomatous, Sessile Serrated, and Synchronous Adenomatous and Sessile Serrated Polyps.

Studies have found a positive association between metabolic risk factors, such as obesity and diabetes, and adenomatous polyps (AP). However, fewer studies have assessed the association between sessile serrated polyps (SSP) or synchronous diagnosis of APs and SSPs (synch polyps). Study participants ( = 1,370; ages 40-85) undergoing screening colonoscopy were enrolled between August 2016 and February 2020.

Angiotensin II antagonism is associated with reduced risk for gastrointestinal bleeding caused by arteriovenous malformations in patients with left ventricular assist devices.

Background: Angiogenesis is implicated in formation of gastrointestinal arteriovenous malformations (AVMs). Angiotensin II signaling is involved in angiogenesis through the vascular endothelial growth factor (VEGF) and angiopoietin-2 pathways. We hypothesized that angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) therapy would be associated with a reduced risk of all-cause gastrointestinal bleeding (GIB) and AVM-associated GIB in patients with left ventricular assist devices (LVADs).

Hospital experience and outcomes for esophageal variceal bleeding.

Objective: Although higher hospital volume has been associated with better outcomes for many surgical procedures, this relationship does not appear to hold for most common medical diagnoses. We evaluated whether there is a volume-outcome relationship for a rarer and higher-mortality medical diagnosis, esophageal variceal bleeding.

Design: Cross-sectional retrospective study of hospital discharge data.
