Yesterday I had the honor of receiving the Best Teacher Award in Pediatric Subspecialty.Moments like this are deeply humbling because they serve as a reminder that our impact is often measured not by publications, titles or accolades but by the people we invest in. #mentorship

📣 New in the November issue of Gastroenterology:
🔹A joint AGA/AASLD guideline on the management of #PBC
🔹Research on how epithelial sulfide loss triggers Barrett’s esophagus
🔹A randomized trial of computer-aided adenoma detection during colonoscopy

🚨 The most comprehensive head-to-head comparison of obesity drugs to date just published in The BMJ.
📊 262 randomized trials. 99,791 participants. 19 drugs. Mean weight change vs lifestyle alone at 1 year:
💉 Tirzepatide −14.9%
💉 CagriSema −14.8%
💊 Oral semaglutide −10.9%
💊 Orforglipron −9.9%
💉 Subcutaneous semaglutide −9.8%
💊 Phentermine-topiramate −8.1%
⚖️ Increased GI adverse events across the board.
Increased fatigue was notable most among orforglipron, CagriSema, and naltrexone-bupropion
No meaningful benefits in quality of life metrics were noted.
💉 The pipeline agents ecnoglutide, mazdutide, retatrutide land in the 13–15% range, but the data are early.
🔑 A network meta-analysis is not a substitute for direct comparisons, and cross-trial populations differ.

🩺 With #MASLD affecting nearly 1 in 3 U.S. adults, the AGA's updated Clinical Care Pathway incorporates the latest evidence on disease nomenclature, risk stratification, diagnosis, and treatment, including newly approved therapies.

🆕🔥Expert Clinical #Consensus on #BodySurfaceGastricMapping Phenotypes for #Gastroduodenal Disorders: ‘Auckland Classification’ v1.0‼️
🎯Evidence & mechanism-based treatment options are suggested for each BSGM-defined phenotype💡
👉 onlinelibrary.wiley.com/doi/…
@ANMSociety @esnm_eu
ALT The Auckland Classification v1.0, derived by international consensus, presents a structured framework for body surface gastric mapping-defined patient phenotypes. This classification provides a foundation for research and a standardized pathway for integrating BSGM into clinical care.

Asymptomatic on PPIs ≠ acid controlled. Nearly 1 in 3 Barrett’s patients had abnormal acid exposure on pH-impedance testing and higher neoplasia risk. Time to consider physiology-guided care? Figures courtesy @AGA_CGH. #BarrettsEsophagus #GERD

🆕🔥Association between #PersonalityTraits & #IBS‼️
🎯#Neuroticism appears to play a central role within a network linking dispositional vulnerability, GI-specific anxiety, abdominal pain & HrQoL💡
👉 onlinelibrary.wiley.com/doi/…
#GutConnectome🔁#BrainConnectome🧠
@ANMSociety @esnm_eu
ALT Key Points • In IBS-patients neuroticism is associated with increased gastrointestinal-specific and generalized anxiety and abdominal pain. • Neuroticism is associated to decreased mental health-related quality of life. • Extraversion shows an opposing pattern to neuroticism in IBS-patients, reflecting a strong underlying relation to neuroticism.
Today at Crohn’s&Colitis Take Steps💙
Every step is a reminder of why we do this work: to support folks living with IBD, to advocate for better care, and to fund the research that moves us forward. #CrohnsAndColitisWalk #IBDAdvocacy #PediatricGI @CrohnsColitisFn

Not just weight loss—metabolic restoration! 🧬 Survodutide (Dual Glucagon/GLP-1) reduced liver fat by an incredible 63% and visceral fat by 34%. 61% of MASLD patients saw complete liver fat normalization.

There are 19 types of cancer associated with obesity. But only a limited number have a very strong association. Two excellent review papers today @NatMetabolism

Not every day you see an odds ratio of 50 (for interleukin-10 autoantibodies and a common HLA allele).
~80% of patients with inflammatory bowel disease (IBD) have this HLA allele
These individuals (~3.5% of IBD) may benefit from B cell depletion (such as achieved via CAR T).

Thrilled to share our recent #Editorial @NGMJournal🆕🔥
📢From Symptoms to Signatures: Proteome-Defined Endotypes in #FunctionalDyspepsia‼️
With Prof. @BMoshiree 🙏😇
⏩FD patients who appear clinically indistinguishable often harbor fundamentally different mucosal programs. Some are dominated by microbial🦠-triggered #immunity in the stomach; others by type-2 inflammation, oxidative stress, or #mast-cell–neural crosstalk in the duodenum💡
🎯The next era should integrate the #Rome V multidimensional clinical profile—capturing both the lived illness experience with biomarkers revealing underlying tissue micro-organic pathology and the circuits that drive it👏
📌#Mechanism-guided, #precision neurogastroenterology offers genuine hope for novel #therapeutics that restore gut-brain🧠homeostasis.
✅ In FD, as in so many #DGBIs, the pathophysiological basis should ultimately guide treatment decisions more than symptom similarity🙌
