Today's interesting paper: the potential environmental hazard profile of some UC drugs The authors used computer-based toxicity prediction tools (in silico QSAR models) to estimate human & environmental toxicity of 5ASA, prednisone & azathioprine, looking at bioaccumulation, aquatic toxicity, microbial toxicity and predicted off-target effects 🧐Main finding was that 5ASA appeared to have the most environmentally favorable profile, with ⬇️predicted bioaccumulation and aquatic toxicity, while prednisone showed the highest predicted systemic and ecological hazard, and AZA ranked in between What I found most interesting is not necessarily the specific rankings, but the broader concept itself: should we start thinking about the environmental footprint of IBD therapies as part of sustainable healthcare and “green gastroenterology”? That said, the study has MAJOR limitations: -entirely computational (no real-world environmental measurements) -no PEC/PNEC calculations (not a true environmental risk assessment) -no experimental validation -biologics could not even be analyzed Still, an intriguing reminder that future discussions around IBD treatment may eventually include not only efficacy and safety, but also sustainability and environmental impact

@DDWMeeting 🍒 on top? Seeing some GI baddies in the wild 😌

@DDWMeeting included not only education and poster time but a little bit (actually a lot) of fun ✨

@DDWMeeting was absolutely amazing. I’m truly grateful for the opportunity to be in the same space as individuals who inspire and motivate me. At every point, attendings are sharing their experience, wisdom and advice with such grace and patience. I’m grateful to the fellows who not only work tirelessly in their academic and professional pursuits but also take a moment to speak to residents. My fellow residents, from all programs, it’s amazing how unified we are in the pursuit of a future in GI. Walking the poster hall, random chats at booths and mixers - core memories made.

@SidraShakeelAh3 - I can’t express how much of an amazing woman, clinician, and friend she is 🤎✨ wishing all this & more in the future

Grateful to be at #ddw2026: learning, presenting, and connecting with some of the brightest minds in GI. Thank you for this amazing opportunity @BilalMohammadMD and @RahulKarnaMD. @DDWMeeting #gastroenterology #GItwitter #gi

We laughed, cried & celebrated Empowerment is recognizing our own value, elevating each other & creating space to be vulnerable in our failures & successes TY @AmerGastroAssn for your commitment to⏩ health & gender equity in GI Grateful to share this w ppl I admire & love

“How much more are we going to talk about women in medicine? Women in GI? What’s the big deal?” Incredible talk by @rina_sanghavi showing us why this is a big deal 👇 📈 Women in GI: +219% growth 📉 Women in leadership: 24% → 34% over a decade That’s not alignment. That’s a gap. And underneath it: • Pay gaps at every rank • RVU models reward volume over value • More time with patients, less “credit” • More non-promotable work • Less sponsorship, fewer leadership paths So no, we’re not “just talking about it.” We’re measuring it. We’re naming it. We’re pushing on it. Because if you don’t track it, you can ignore it. If you don’t challenge it, it stays. This isn’t a pipeline problem. It’s a progression problem. And until that gap closes, we’re not done.

☕️ Good morning from Day 2️⃣ of #DDW2026 ✨ The OG Nebraska squad is here and we’re living it up in the windy city like no other 💃🏻🕺🏻 Lookin’ dapper for @DDWMeeting 😎 @UNMC_GIHEP @CreightonGI

🌟 Started another exciting day at #DDW2026 with our second oral talk 🎤✨ comparing early-onset and late-onset CRC 🔬 and highlighting interesting, promising findings! Deeply grateful to Dr. Shaukat @AasmaShaukatMD for her outstanding support, mentorship, and guidance throughout this project 🙏🌟

Authentic & Organically Joyful is how I would define Scrubs n Heels 🩺👠❤️‍🔥 Sharing a few stills, a moment in time. The 5th Annual Summit was determined to teach us that we are not replaceable—but a singular force. That setbacks are not failures but the shape of a nonlinear path. A journey. SnH spoke to productivity not equating to purpose…instead, we must define our own meaning, our own wealth, our own impact. Find what moves us & pay it forward. We must hold boundaries without apology. Speak up for our worth, our work, and our future—even in the face of tall poppy syndrome & most importantly, we must honor the season we’re in—let it guide our pace, our priorities, our next step.
