Show Notes
In this special live episode from the 2025 North American Congress of Clinical Toxicology (NACCT), Ryan takes you inside the conference to hear directly from the researchers themselves. Covering 11 abstracts that span high-stakes management decisions, surprising case reports, and challenges to toxicology dogma, this year’s highlights feature everything from amlodipine overdoses to naturopathic misadventures, metformin-associated blindness, and more. The show kicks off with a foreword from Ryan and Dr. Jon Cole (abstract co-chair for AACT) discussing some of their favorite research from the conference.
If you couldn’t make it to NACCT or just want to catch up on some of the most impactful new research in our field, this episode will give you a front-row seat. Check below for links to the published abstracts, the full list of studies discussed, and timestamps for where you can hear each one.
