Clinicians in the Department of Gastroenterology, Hepatology and Endoscopy at Brigham and Women’s Hospital and colleagues explored the prevalence and perceptions of the GI hospitalist model in academic GI departments across the United States. They report GI hospitalists are relatively common and geographically diverse.


Transcriptional Profile Overlaps in PPI-Responsive and -Nonresponsive Eosinophilic Esophagitis

Researchers at Brigham and Women’s Hospital hypothesized that differences in mucosal gene transcript expression might explain the differences in PPI treatment response. Instead, they found the transcriptional profiles in patients with PPI-responsive and -nonresponsive eosinophilic esophagitis are remarkably similar.


Actively Triggerable Aluminum for Gastrointestinal Applications

Researchers in the Division of Gastroenterology, Hepatology and Endoscopy at Brigham and MIT address limitations of metals in medical devices by using liquid metal embrittlement, long viewed as a failure mechanism to be avoided, to stimulate on-demand breakdown of solid aluminum.


Intelectin-1 Contributes to the Severity of Ulcerative Colitis

Colorectal cancer surgeon Nelya Melnitchouk, MD, MSc, and emergency medicine physician Eric Goralnick, MD, MS, created a Ukrainian-language Stop the Bleed video that shows laypeople how to care for a traumatic injury. This is just one of Dr. Melnitchouk’s many efforts to improve trauma—and cancer—care in Ukraine.

Joshua R. Korzenik, MD, director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital, and colleagues have created an interactive, mobile-delivered elimination diet program for IBS and dual IBS/IBD that’s powered by machine learning that delivers precise and personalized recommendations.


How Can Doctors Predict Patient Response to Weight Loss Surgery?

Brigham researchers found that patients with higher pre-operative levels of the hunger hormone ghrelin respond better to gastric bypass surgery than those with lower levels. Minimally invasive and bariatric surgeon Ali Tavakkoli, MD, says this suggests a crucial role for ghrelin in driving postoperative outcomes.


Editorial: GI Testing in Patients With Limited English Proficiency

A study at the Mayo Clinic is the first to examine broadly and systematically the impact of patients’ limited English proficiency (LEP) on procedure-related gastroenterology care. In an editorial, Mass General Brigham clinicians comment on the study results, its limitations, and directions for additional research.


Brigham Hosts Country’s First High-Resolution Anoscopy Course for Colorectal Surgery Fellows

High-resolution anoscopy can be a helpful tool for identifying precancerous lesions in the anal canal. Colon and rectal surgeon James Yoo, MD, and infectious disease specialist Jennifer A. Johnson, MD, both of the Brigham, developed and recently hosted a course to educate colorectal fellows on the technique.


Roux-en-Y Gastric Bypass May Not Be As Safe As Sleeve Gastrectomy for Black and Latino/a/x Patients

Caroline M. Apovian, MD, and team determined that the variability of weight loss and hemoglobin A1C across racial/ethnic groups was small after Roux-en-Y gastric bypass (RYGB) compared with sleeve gastrectomy (SG). However, safety concerns were greater for Black and Latino patients after RYGB than SG.
