Competitive endogenous RNA (ceRNA) regulation suggested complex network of all transcript RNAs including long noncoding RNAs (lncRNAs), which can act as natural miRNA sponges to inhibit miRNA functions and modulate mRNA expression. Until now, the specific ceRNA regulatory mechanism of lncRNA-miRNA-mRNA in colorectal cancer (CRC) still remains unclear. ⋯ We identified significantly altered lncRNAs, miRNAs and mRNAs in colorectal carcinogenesis, which might serve as potential biomarkers for tumorigenesis of CRC. In addition, the ceRNA regulatory network of lncRNA-miRNA-mRNA was constructed, which would elucidate novel molecular mechanisms involved in initiation and progression of CRC, thus providing promising clues for clinical diagnosis and therapy.

The role of TL1A in the intestinal mucosa barrier in inflammatory bowel disease (IBD) is still unclear. This study was aimed to investigate the expression levels of tight junction protein (TJ), myosin light chain kinase (MLCK), MyD88 and tumor necrosis factor (TNF) receptor-associated factor-6 (TRAF6) and how TL1A influences the intestinal barrier in IBD. ⋯ The results suggested that TL1A could impair intestinal epithelial barrier in the mouse model of IBD and might regulate TJ expression via MLCK/p-MLC pathway and LPS-mediated MyD88/TRAF6 pathway.

Case Reports
Off-Label Teduglutide Therapy in Non-intestinal Failure Patients with Chronic Malabsorption.
Teduglutide, a glucagon-like peptide 2 analog, has demonstrated efficacy in treating adult patients with short bowel syndrome (SBS) and dependence on parenteral nutrition (PN), but its role in chronic malabsorptive states that do not necessitate PN remains uncertain. ⋯ The use of teduglutide might be broadened to include patients with functional SBS not meeting strict criteria for intestinal failure. Further studies should evaluate the efficacy of teduglutide in patients who may require short-term small intestine rehabilitation or who have chronically impaired absorptive capacity not yet requiring PN.

To assess publicly available content derived from official websites of accredited gastroenterology fellowship programs, specifically evaluating data pertinent to prospective applicants. ⋯ Gastroenterology fellowship websites lacked important content. Websites had a lower mean percentage of lifestyle content compared to training and program-related items. An organized website containing relevant information may not only attract qualified applicants but also avert unnecessary email inquiries and inappropriate applications. This study may provide guidance to gastroenterology fellowship programs seeking to improve their websites for applicants.

Randomized Controlled Trial Multicenter Study Comparative Study
Short-Term Symptomatic Relief in Gastroesophageal Reflux Disease: A Comparative Study of Esomeprazole and Vonoprazan.
Proton pump inhibitors and vonoprazan (a potassium-competitive acid blocker) are recommended as first-line treatments for gastroesophageal reflux disease (GERD). However, few reports have investigated the onset of action of these agents for GERD symptom relief. The present study compared the symptom relief of esomeprazole with that of vonoprazan via monitoring self-reported GERD symptoms after treatment initiation. ⋯ There were no substantial differences in the symptom relief between the two groups at any time point in this short-term study.
