• Alterations in Fecal Fungal Microbiomes of Patients With COVID-19

Alterations in Fecal Fungal Microbiomes of Patients With COVID-19

Patients hospitalized with COVID-19 have alterations in their fecal mycobiomes, including enrichment of fungal pathogens from the genera Candida and Aspergillus, compared with controls researchers report in the October issue of Gastroenterology. Unstable gut mycobiomes and prolonged dysbiosis persisted in a subset of patients with COVID-19 for as long as 12 days after nasopharyngeal

  • How Do Diet and Antibiotic Use Affect Risk of Colorectal Tumor Recurrence?

How Do Diet and Antibiotic Use Affect Risk of Colorectal Tumor Recurrence?

Researchers have identified mechanisms by which diet and antibiotic use together promote tumorigenesis by colon cancer cells at the anastomosis after colorectal surgery, reported in the March issue of Gastroenterology. Strategies to prevent emergence of these microbe communities or their enzymatic activities might be used to reduce the risk of

  • Is Red Wine Consumption Good for Your Intestinal Microbiome?

Is Red Wine Consumption Good for Your Intestinal Microbiome?

Consumption of red wine increases gut health, based on α-diversity of the intestinal microbiome, researchers report in the January 2020 issue of Gastroenterology. White wine had only weak effects, whereas beer, cider, spirits had none. The researchers propose that even infrequent red wine consumption benefits gut health, possibly via effects

  • How Is The Intestinal Microbiome Altered in Patients With IBD and Does it Change During Therapy?

How Is The Intestinal Microbiome Altered in Patients With IBD and Does it Change During Therapy?

Treatment of inflammatory bowel diseases (IBD) with anti-tumor necrosis factor (anti-TNF) drugs restores diversity to the intestinal microbiome, researchers report in the November issue of Gastroenterology.  The study associates metabolic interactions among luminal bacteria with outcomes of therapy. Altered interactions between the mucosal immune system and intestinal microbiota contribute to

  • Can a Food-based Diet Replace Exclusive Enteral Nutrition for Patients With Crohn’s Disease?

Can a Food-based Diet Replace Exclusive Enteral Nutrition for Patients With Crohn’s Disease?

An individualized, food-based diet with similar composition of nutrients to exclusive enteral nutrition (EEN), causes similar changes in the microbiomes of patients with Crohn’s disease (CD), reduces gut inflammation, and is preferred by patients, researchers report in the April issue of Gastroenterology. Non-medical treatments are needed for patients with CD. Diet

  • What is in Transplanted Fecal Microbiota That Cures Clostridium difficile Infection?

What is in Transplanted Fecal Microbiota That Cures Clostridium difficile Infection?

Researchers have identified a microbiota metabolite that is depleted by the antibiotic clindamycin and replaced with fecal microbiota transplantation (FMT), mediating its effects on recurrent Clostridioides difficile (Clostridium difficile) infection (CDI). Reporting in the November issue of Gastroenterology, the researchers propose that this bacterial metabolite, valerate, might be used in safer and

  • Effects of Diet, Intestinal Inflammation, and the Microbiome on Risk of Colorectal Cancer

Effects of Diet, Intestinal Inflammation, and the Microbiome on Risk of Colorectal Cancer

Diets that promote intestinal inflammation can increase risk of colorectal carcinomas associated with specific bacteria in the microbiome, researchers report in the October issue of Clinical Gastroenterology and Hepatology. Diet-induced intestinal inflammation alters the gut microbiome to contribute to colorectal cancer risk, which might be reduced with dietary changes. Chronic inflammation

  • Are Prebiotics or Diets Low in FODMAPs Better for Patients With Functional GI Disorders?

Are Prebiotics or Diets Low in FODMAPs Better for Patients With Functional GI Disorders?

Intermittent administration of prebiotics might be an alternative to dietary restrictions for patients with functional gut symptoms, researchers report in the October issue of Gastroenterology. A diet low in fermentable oligo-, di-, mono-saccharides and polyols (low-FODMAP diet) reduces symptoms of irritable bowel syndrome (IBS), and patients with gas-related symptoms can significantly

  • What are the Challenges to In Vitro Maturation of Hepatic Stem Cells?

What are the Challenges to In Vitro Maturation of Hepatic Stem Cells?

New approaches are needed to generate and maintain stable and mature adult liver cells ex vivo. In the April issue of Gastroenterology, Bart Spee and colleagues review factors that promote hepatocyte differentiation and maturation, and consider criteria for establishing whether cells derived from stem cells are fully mature hepatocytes. They discuss challenges to cell transplantation and

  • Does Asthma Increase Risk for Inflammatory Bowel Diseases?

Does Asthma Increase Risk for Inflammatory Bowel Diseases?

A population-based case–control study published in the September issue of Clinical Gastroenterology and Hepatology associates asthma with later development of Crohn’s disease (CD) and with ulcerative colitis (UC). Although the etiology of asthma and inflammatory bowel diseases (IBD) are not well understood, they both involve complex interactions among genetic and environmental factors and the
