Medically Associated Science and Technology Program @CedarsSinai A multidisciplinary team studying the human #microbiome and finding new ways to help patients
We're working to build more solutions for conditions of the microbiome - from #IBS and ##SIBO to PCOS and #Diabetes. How can you help? support.cedars-sinai.edu/give/f2127909/…
📰 ICYMI: Our #ENDO2025 abstract is making headlines! We’re excited to see our oral featured in @Medscape, which did an excellent job highlighting our key findings on how hypothyroidism may impact the small bowel #microbiome. The article also includes insights directly from our…

It now seems obvious but a great deal of work went into understanding the role of #methane and #contipation now called #IMO, setting up new drug therapy. Here we present the cause and effect evidence for methane causing constipation from @MASTprogram @CedarsSinai #theMAST5years
MAST’s @MarkPimentelMD is featured in a recent @WebMD article exploring the long-term effects of traveler’s diarrhea & its potential link to #IBS The article highlights his work on how the immune system may mistakenly produce antibodies against vinculin, a human protein, after…

💭Newest MAST paper! Our latest research shows that breath gas profiles are influenced, at least in part, by small bowel microbial composition 😮💨 🤝🦠 📈Higher breath H₂S is linked to H₂S-producing bacteria & is associated with looser stools 💨 Elevated CH₄ is associated with…

What does #WorldMicrobiomeDay mean to those of us at MAST? Let’s find out! 👇 Overall, today is a great chance to spread awareness on the small bowel microbiome & how it impacts different aspects of health and disease Visit our website to catch up on the latest!…
Paper out! Methane and Hydrogen sulfide on three-gas breath test correlate with methanogens and H2S producers in the SMALL INTESTINE! M. smithii for methane and Proteus and Desulfovibrio for H2S, among others. Methane=constipation, H2S the opposite. doi.org/10.1007/s10620…
Most #IBS drug studies focus on what works. But what about harm? We analyzed 54 clinical trials to calculate number needed to harm (NNH) for common IBS meds 🔍 Key: - Rifaximin=safest - Tricyclics, alosetron, tenapanor=highest risk - NNH + NNT=better patient-centered decisions…

Some Wednesday Wisdom from #DDW2025! Throwing it back to MAST's @MarkPimentelMD closing out his ‘SIBO: Hype or Hip?’ presentation with a powerful reminder: #SIBO is real and there is ✨HOPE✨ in the progress being made through research to understand, diagnose, and treat it…

Artificial sweeteners aren’t just in your snacks anymore… they’re in your vape A @nourishbywebmd article investigates neotame, a next-gen sweetener found in many disposable e-cigarettes & ultra-processed foods. MAST physician-scientist @RuchiMathurMD weighs in on the growing…

Today we celebrated an emotional (and fun!) farewell as we sent off Mo, Sepideh, and Dilara on their next big adventures- residency and medical school! Wishing you all the success in this next chapter of your careers. Once a MASTer, always a MASTer! 🫶




In this study, we examine the safety of drugs for #IBS. It turns out that tricyclic antidepressants are among the drugs patients are most likely to stop due to adverse events. journals.lww.com/ajg/abstract/9…
Now in press‼️🚨📢 Adding to the dialogue, the newest evidence-based consensus on perioperative management for patients taking GLP-1 RAs informed by a systematic review of clinical outcomes and gastric emptying data Proud to share that MAST endocrinologist @RuchiMathurMD was a…
