A randomized trial at a community health center showed that patient navigation significantly increased colonoscopy completion among patients with an abnormal FIT result. While only 14% of patients receiving usual care completed a follow-up colonoscopy within a year, 94% of those who received navigation services did so—a seven-fold improvement. Navigation was provided by bilingual clinical staff and included personalized support like barrier resolution, bowel prep instructions, and procedure reminders.

This study evaluated the performance of three AI chatbots—ChatGPT-4.0, ChatGPT-3.5, and Gemini Advanced—in interpreting 20 real-world gastrointestinal pathology cases. Each model was assessed on its diagnostic accuracy, ability to generate differential diagnoses, interpret immunohistochemical stains (IHC), provide a concise final diagnosis, and explain its reasoning. Two GI pathology experts independently graded the responses using a five-point system.

The FDA has approved Tremfya (guselkumab) for moderate to severe Crohn’s disease, offering a convenient at-home self-injection option in addition to IV infusion. This IL-23 inhibitor is the first of its kind to also target CD64+ cells, enhancing its effectiveness. Clinical trials showed significant remission rates—up to 65% at 48 weeks—among patients who had not responded to standard treatments. Already approved for psoriasis, psoriatic arthritis, and ulcerative colitis, Tremfya now brings flexibility and new hope to Crohn’s patients through a more accessible treatment option.
