Unlabelled: In the gut, microRNAs (miRNAs) produced by intestinal epithelial cells are secreted into the lumen and can shape the composition and function of the gut microbiome. Crosstalk between gut microbes and the host plays a key role in irritable bowel syndrome (IBS) and inflammatory bowel diseases, yet little is known about how the miRNA-gut microbiome axis contributes to the pathogenesis of these conditions. Here, we investigate the ability of miR-21, a miRNA that we found decreased in fecal samples from IBS patients, to associate with and regulate gut microbiome function.

Objective: High body mass index (BMI) may reduce ulcerative colitis (UC) treatment efficacy. Etrasimod is an oral, once-daily (QD), selective sphingosine 1-phosphate (S1P)1,4,5 receptor modulator for the treatment of moderately to severely active UC. This post hoc analysis assessed treatment outcomes according to BMI in ELEVATE UC 52 and ELEVATE UC 12.

Background And Aims: Patient-reported outcomes (PROs) are vital in assessing disease activity and treatment outcomes in inflammatory bowel disease (IBD). However, manual extraction of these PROs from the free-text of clinical notes is burdensome. We aimed to improve data curation from free-text information in the electronic health record, making it more available for research and quality improvement.

Article Synopsis
- The study explores the unclear mechanisms behind abdominal aortic aneurysm (AAA) by analyzing gut microbiota in fecal samples from patients with AAA and healthy controls.
- It was found that patients with AAA had higher levels of certain oral bacteria and lower levels of bacterial genes associated with alpha lipoic acid (ALA) biosynthesis in their feces.
- These findings suggest potential for developing gut microbiome-based treatments for AAA, highlighting the role of gut bacteria in the condition's pathophysiology.

Slow transit constipation (STC) is a colonic motor disorder characterized by a marked delay in the movement of substances through the colon. Traditional Chinese medicine (TCM) is a treasure trove of natural compounds, which is effective in treating constipation with relatively minor side effects. Zengye decoction (ZYD), a classic herbal formula in TCM, is used for moistening the intestines and relieving constipation.
