Chadi sits down with Dr. Sylvia Owusu-Ansah, a pediatric emergency physician at UPMC, to discuss her role as a medical advisor for the HBO Max series “The Pitt” and how she helped bring real-world authenticity to the show. She explains how the writers first approached her and asked a key question—what stories have not yet been told on medical dramas—which led her to highlight issues such as the challenges of sickle-cell pain management and share the powerful real-life story of a 17-year-old patient that ultimately inspired a storyline in the series. Dr. Owusu-Ansah also reflects on how her own experiences, including those as a Black physician in emergency medicine, informed the perspectives she brought to the writers’ room, and she discusses what “The Pitt” portrays most accurately about life in the ER and how the show differs from traditional medical dramas in its approach to realism.Read more about Dr. Owusu-Ansah’s inspiration for “The Pitt.”https://www.health.pitt.edu/news/pitt-doctor-sylvia-owusu-ansahs-story-influenced-upcoming-series-pittCheck out Chadi’s website for all Healthcare Unfiltered episodes and other content. https://www.chadinabhan.com/Watch all Healthcare Unfiltered episodes on YouTube. https://www.youtube.com/channel/UCjiJPTpIJdIiukcq0UaMFsA

Chadi sits down with award-winning legal scholar Elizabeth (Beth) Chamblee Burch to explore “The Pain Brokers: How Con Men, Call Centers, and Rogue Doctors Fuel America’s Lawsuit Factory,” her deeply reported investigation into a multilevel scam involving a pelvic mesh product that preyed on vulnerable patients and exploited mass tort litigation. Together, they discuss how she uncovered her sources and evidence, the harrowing stories of the women caught up in this web of telemarketing, shady medical referrals, and legal profiteering, and what the fallout reveals about the broader tort law system.Read more about The Pain Brokers.https://www.simonandschuster.com/books/The-Pain-Brokers/Elizabeth-Chamblee-Burch/9781668068861Check out Chadi’s website for all Healthcare Unfiltered episodes and other content. https://www.chadinabhan.com/Watch all Healthcare Unfiltered episodes on YouTube. https://www.youtube.com/channel/UCjiJPTpIJdIiukcq0UaMFsA

Paolo Tarantino, MD, PhD, medical oncologist at Dana-Farber Cancer Institute, joins Chadi for a deep dive into the rapidly evolving world of antibody-drug conjugates (ADCs)—sometimes dubbed “super-chemotherapies.” He traces the fascinating origins of the ADC concept, including a centuries-old scientific insight that foreshadowed their development, and explains the biology behind how these targeted therapies deliver potent cytotoxics directly to cancer cells across tumor types. Dr. Tarantino also reflects on launching his career alongside the infancy of modern ADCs, explores innovations like multi-payload constructs, and weighs in on whether ADCs could ultimately replace conventional chemotherapy as research continues to push the field forward.Check out Chadi’s website for all Healthcare Unfiltered episodes and other content. https://www.chadinabhan.com/Watch all Healthcare Unfiltered episodes on YouTube. https://www.youtube.com/channel/UCjiJPTpIJdIiukcq0UaMFsA

Chadi sits down with Nora Disis, MD—Editor in Chief of JAMA Oncology and professor at Fred Hutchinson Cancer Center—for a candid, wide-ranging discussion on the modern state of peer review and medical publishing. Dr. Disis reflects on the founding of JAMA Oncology and her role as its inaugural Editor in Chief, then pulls back the curtain on what actually happens when a manuscript is submitted (yes, she reads every one), how impact factors shape—and sometimes distort—the field, and what truly defines a high-quality peer reviewer. From the promises and pitfalls of AI to the pressures facing academic publishing today, this is a raw, thoughtful, and at times critical look at how medical evidence gets vetted and shared with the world.Check out Chadi’s website for all Healthcare Unfiltered episodes and other content. https://www.chadinabhan.com/Watch all Healthcare Unfiltered episodes on YouTube. https://www.youtube.com/channel/UCjiJPTpIJdIiukcq0UaMFsA
