500 Posts by the AGA Journals Blog

This week the AGA Journals Blog has reached an important milestone — its 500th post! The blog was started in 2010 to help disseminate the important discoveries published in the AGA Journals to a broader audience. Eight years and over 132,000 views later, it has updated its readers on everything from biomarkers for colon

  • Does Mucosal Inflammation Cause Diverticulosis?

Does Mucosal Inflammation Cause Diverticulosis?

Despite limited evidence that a chronic state of low-grade mucosal inflammation contributes to development of diverticulosis, a prospective study published in the June issue of Clinical Gastroenterology and Hepatology found no correlation of the disease with mucosal inflammation, upregulated immune markers, or gastrointestinal symptoms. Colonic diverticulosis (outpouchings from the colonic lumen) is

Gastroenterology Special Issue on Endoscopy

A special issue of Gastroenterology, Advances in Endoscopic Therapy, presents the latest advances in gastrointestinal endoscopy, including endoscopic images and videos. In their introductory article, Jacques J. Bergman and Patrick S. Yachimski explain that endoscopy is central to gastroenterology clinical practice and research, allowing examination of healthy and diseased tissue from the organ level, to the

  • Model: Microfabricated Crypt Scaffolds for Studying Human Colon Stem Cells

Model: Microfabricated Crypt Scaffolds for Studying Human Colon Stem Cells

Researchers created an in vitro human colon crypt array that provides an accurate representation of human intestinal crypts, reported in the February issue of Cellular and Molecular Gastroenterology and Hepatology. This system re-creates an intestinal epithelium with a high density of polarized crypts that respond in a physiologic manner to growth factors, metabolites, or

  • Intestinal Microbes as Carcinogens

Intestinal Microbes as Carcinogens

Fecal microbiota from patients with colorectal cancer (CRC) have carcinogenic properties, researchers report in the December issue of Gastroenterology. Feeding mice stool from patients with colorectal cancer (CRC) increased numbers of polyps, levels of intestinal dysplasia and proliferation, and markers of inflammation in colon, compared with stool from individuals without CRC, the scientists found.

  • 3-D Imaging of T-cell Localization in Inflamed Colon Tissues

3-D Imaging of T-cell Localization in Inflamed Colon Tissues

Light sheet fluorescence microscopy (LSFM) provides accurate 3-dimensional images of inflammed intestine of mice with colitis, researchers show in a Gastroenterology in Motion article and video in the October issue of Gastroenterology. The authors demonstrate use of the technology to analyze migration of human T cells in colons of mice with colitis. Improved techniques are

  • Hemosuccus Pancreaticus Caused by a Pancreatic Tumor

Hemosuccus Pancreaticus Caused by a Pancreatic Tumor

Researchers describe a rare cause of hemosuccus pancreaticus in a patient with pancreatic cancer. The gastrointestinal bleeding was caused by erosion of pancreatic adenocarcinoma into the colon, they show in the April issue of Clinical Gastroenterology and Hepatology. Hemosuccus pancreaticus is defined as hemorrhage from the ampulla of Vater via the pancreatic

  • What is the Active Ingredient in FMT for CDI?

What is the Active Ingredient in FMT for CDI?

Sterile fecal filtrates—containing bacterial debris, proteins, antimicrobial compounds, metabolic products, and microbial DNA, rather than intact microorganisms—appear to be effective for treatment of recurrent Clostridium difficile infection (CDI), researchers report in the March issue of Gastroenterology. Fecal microbiota transplantation (FMT) is an effective therapy of recurrent CDI—a single treatment resolves

  • What can we do with Gastrointestinal Organoids?

What can we do with Gastrointestinal Organoids?

Researchers review the latest discoveries from studies of tissue-derived and pluripotent stem cell–derived intestinal, gastric, esophageal, liver, and pancreatic organoids in the May issue of Gastroenterology. Studies of organoids have provided valuable information about GI development, tissue homeostasis, and disease and might be used to develop personalized medicines. In vitro organoid cultures are

  • What is the Best way to Manage Diverticulitis, and how Many People Have it?

What is the Best way to Manage Diverticulitis, and how Many People Have it?

Not all patients with multiple episodes of diverticulitis should undergo preventative surgery, shows a Markov decision model published in the January 2016 issue of Clinical Gastroenterology and Hepatology. Elective surgery after 2 episodes produces fewer quality-adjusted life-years (QALYs) than surgery after 3 episodes or conservative or medical treatments, the model found.
