Host: Peter Buch, MD, FACG, AGAF, FACP Guest: William Grady, MD While colorectal cancer is the second most common cause of cancer deaths, only a third of people between the ages of 45 and 75 are compliant with screening recommendations. However, cell-free DNA blood-based tests could become a new option for colorectal cancer screening. Dr. Peter Buch sits down with GI expert Dr. William Grady to discuss the efficacy of this new test and where it is in the FDA approval process.

Guest: Andres J. Yarur, MD Obesity has recently surfaced as an important topic in patients with inflammatory bowel diseases, such as Crohn’s and ulcerative colitis, but historically, these patients have been underweight. This led to the phase III pivotal trials for the use of upadacitinib in patients with moderate to severe ulcerative colitis and Crohn’s disease to see how their baseline BMI would influence the efficacy of the drug. To hear the details and findings of this study, join Dr. Andres Yarur, Associate Professor of Medicine at Cedars Sinai Medical Center in Los Angeles, California. He also presented this study at Digestive Disease Week 2024.

Tune in to hear Dr. Andres Yarur discuss essential health maintenance strategies for patients with IBD. Dr. Yarur is an Associate Professor of Medicine at Cedars Sinai Medical Center in Los Angeles, California.

Host: Peter Buch, MD, FACG, AGAF, FACP Guest: Michael Camilleri, MD When it comes to irritable bowel syndrome (IBS), it’s important to keep in mind that there are certain diagnoses clinicians can make to specifically treat the underlying problem that’s causing the symptoms that suggest IBS.

Host: Peter Buch, MD, FACG, AGAF, FACP Guest: David P. Hudesman, MD There’s been an increase in the elderly irritable bowel disease (IBD) population, and it’s estimated that a third of our overall IBD population will soon be over the age of 60. When managing and diagnosing these patients, there’s different factors to consider, like polypharmacy, biological versus chronological age, how fit these patients are versus how frail they are, and more. To take a deep dive into how IBD is affecting elderly patients, join Dr. Peter Buch as he speaks with Dr. David Hudesman, Professor of Medicine and Co-director of NYU Langone’s Inflammatory Bowel Disease Center.
