Differentiating Gastrointestinal Stromal Tumors From Leiomyomas of Upper Digestive Tract Using Convolutional Neural Network Model by Endoscopic Ultrasonography
Authors demonstrated that the CTP classification system is a reliable predictor of ERCP complications in patients with cirrhosis. Consequently, caution should be exercised when performing ERCP in patients classified as CTP class C.

Ensitrelvir for Covid-19 Postexposure Prophylaxis in Household Contacts
Early initiation of a 5-day oral ensitrelvir regimen within 72 hours after symptom onset in an index patient significantly reduced the risk of developing Covid-19 among household contacts while maintaining a safety profile comparable to placebo. Clinical benefit was observed across major patient subgroups, including individuals at increased risk for severe disease, and treatment was associated with reduced household transmission. These findings support ensitrelvir as an effective postexposure prophylactic option for household contacts and suggest potential utility in other high-risk exposure settings where rapid outbreak control is needed.

Artificial Intelligence-Assisted Colonoscopy Improves Polyp Detection in a Prospective Randomized Tandem Colonoscopy Study
This prospective randomized tandem study demonstrates that AI-assisted colonoscopy significantly improves overall polyp detection, with the greatest benefit observed for diminutive and Paris type 0-IIa lesions. The enhanced detection was achieved without increasing procedure withdrawal time, supporting the feasibility of real-time AI integration into routine colonoscopic practice. Although false-positive alerts occurred, they were infrequent and readily distinguishable by experienced endoscopists. Given the single-center design, relatively small sample size, and absence of adenoma detection rate analysis, larger multicenter studies are warranted to confirm the clinical impact of AI-assisted colonoscopy on colorectal cancer prevention.

Pharmacogenomic-Informed Antidepressant Prescribing in Australian Primary Care
In this pragmatic double-blind randomized controlled trial conducted in Australian primary care, pharmacogenomic-informed antidepressant prescribing did not improve depressive symptoms compared with prescribing guided by national therapeutic guidelines. Clinical outcomes, medication tolerability, adherence, and quality of life were similar between groups, while cost-effectiveness analyses did not support routine implementation of pharmacogenomic testing in this setting. These findings suggest that broad pharmacogenomic-guided antidepressant prescribing in general practice does not provide additional clinical benefit over guideline-based management, although targeted evaluation in carefully selected patient populations may warrant further investigation.

FDA Approves First Single-Dose Generic Treatment for Influenza
FDA approved the first generic single-dose baloxavir marboxil tablet for influenza in patients aged 5 years and above, ahead of the 20262027 flu season. Approved for both acute uncomplicated influenza treatment (within 48 hours of symptom onset) and post-exposure prophylaxis, this milestone may improve access, affordability, and ease of antiviral use in clinical practice.

Fecal Microbiota Transplant and Multidrug-Resistant Organism Decolonization in Gastrointestinal Disease
This randomized clinical trial found that while a single session of FMT did not significantly enhance MDRO decolonization or decrease AMR genes in patients with GI diseases, it modulated gut microbiome diversity and composition.
