Welcome to a very special episode of DiabetesBio—the American Diabetes Association’s podcast for its flagship research publication, Diabetes. While this podcast usually focuses on the research published in Diabetes, this unique episode focuses on the incredible scholarly content of the 84th Scientific Sessions, which took place 21–24 June in Orlando, FL. Alice Cheng, MD, FRCPC, co-host of Diabetes Care “On Air,” acted as emcee for a panel discussion with Michael Rickels, MD, MS, her co-host on Diabetes Care “On Air”; Kirk Habegger, PhD, Darleen Sandoval, PhD, and Kevin Williams, PhD, the co-hosts of DiabetesBio; and Neil Skolnik, MD, co-host of Diabetes Core Update and Diabetes Day by Day. This episode is being released on three of our professional podcasts: Diabetes Care “On Air,” DiabetesBio, and Diabetes Core Update. This special episode is supported by an independent educational grant from Bayer.

This wide-ranging discussion begins with introductions and brief descriptions of the various podcasts, and then the panelists highlight their favorite sessions and events from the 84th Scientific Sessions—the new, high-impact research presented at the meeting, implications for future research, and clinical considerations and take-aways—across the “bench-to-bedside” spectrum of biomedical research, clinical research, and treatment advances. (Please note that anyone who registered for the event can still access the recorded content at ada2024.org until August 26.)  

Correction: •Dr. Carmella Evans-Molina is from the Indiana University School of Medicine •Dr. Lou Philipson is from the University of Chicago

Welcome to the special Sweet Talk March 2024 episode of DiabetesBio—the American Diabetes Association’s podcast for its flagship research publication, Diabetes. Our host is Dr. Kevin Williams. 

 1:00 Sweet Talk, part 1. Kevin introduces the guests for the first part of Sweet Talk, Dr. Christopher Newgard from Duke University Medical Center and Dr. Louis Philipson from the University of Chicago School of Medicine. They are co-chairs of the American Diabetes Association’s Pathway to Stop Diabetes Mentor Advisory Group. The Pathway program seeks to identify and support exceptional young scientists in the field of diabetes research. Drs. Newgard and Philipson explain the history of the program, expand on the importance of mentorship for young scientists, and relate challenges faced by the program, from funding cuts to the COVID-19 pandemic. 

18:56 Sweet Talk, part 2. To wrap up the episode, Kevin brings in Dr. Céline E. Riera, recipient of a Pathway to Stop Diabetes initiator award in 2015.

Welcome to the March 2024 episode of DiabetesBio—the American Diabetes Association’s podcast for its flagship research publication, Diabetes. In this episode of DiabetesBio, Drs. Kirk Habegger, Darleen Sandoval, and Kevin Williams discuss the latest and greatest content in the March 2024 issue of Diabetes. 

1:15 Before getting underway with this week’s interviews, Kirk gives a quick shout-out to March’s Paper of the Month: “High Doses of Exogenous Glucagon Stimulate Insulin Secretion and Reduce Insulin Clearance in Healthy Humans,” by Gray et al. Although they only mention it in passing, Kirk does offer a ringing endorsement: “It’s excellent work, and all things glucagon are good.” This article is freely available at https://doi.org/10.2337/db23-0201. 

 2:44 Darleen announces that the March DiabetesBio is actually two episodes. The first part features Darleen and Kirk interviewing authors of the feature articles of the month, and the second part is devoted to Sweet Talk with Kevin. In this special episode, Kevin delves into the ADA’s Pathway to Stop Diabetes initiative with two of the initiative’s key members and one of the initiative’s award-winning researchers. 

 4:30 Darleen and Kirk interview Mr. Harry B. Cutler and Dr. David E. James, first and last authors of “Dual Tracer Test to Measure Tissue-Specific Insulin Action in Individual Mice Identifies In Vivo Insulin Resistance Without Fasting Hyperinsulinemia.” They discuss the use of a dual tracer test and describe insights into tissue-specific insulin action. They also raise an interesting question: Could it be that the popular belief that peripheral insulin resistance leads to hyperinsulinemia is inaccurate? This article can be freely accessed at https://doi.org/10.2337/db23-0035. 

 27:50 Kirk and Darleen then host Dr. Lori Sussel, last author of “PTPN2 Regulates Metabolic Flux to Affect β-Cell Susceptibility to Inflammatory Stress.” Dr. Sussel and her group determined that β-cells lacking PTPN2 are more susceptible to inflammatory stress associated with T1D due to impaired glucose-stimulated insulin secretion, mitochondrial defects, and reduced glucose-induced metabolic flux, indicating a role for PTPN2 in maintaining metabolic fitness in β-cells.

Welcome to the February 2024 episode of DiabetesBio—the American Diabetes Association’s podcast for its flagship research publication, Diabetes. In this episode of DiabetesBio, Drs. Kirk Habegger, Darleen Sandoval, and Kevin Williams discuss the latest and greatest content in the February 2024 issue of Diabetes. 

2:25: To kick things off, Darleen and Kirk are joined by Dr. Satya Dash of University Health Network and the Banting & Best Diabetes Centre, University of Toronto. Dr. Dash is the senior author of “Erythritol as a Potential Causal Contributor to Cardiometabolic Disease: A Mendelian Randomization Study.” Do low-calorie sweeteners possibly contribute to cardiometabolic disease? Listen to hear about the results of Dr. Dash’s study. This article can be freely accessed at https://doi.org/10.2337/db23-0330. 

14:52: Next, the Big 10 is well represented when Darleen and Kirk meet with Drs. Jeffrey Hodgin (University of Michigan) and Alan Attie (University of Wisconsin) to discuss their fascinating collaboration on their “Genetic Analysis of Obesity-Induced Diabetic Nephropathy in BTBR Mice.” Drs. Hodgin and Attie’s study can be freely accessed at https://doi.org/10.2337/db23-0444. 

36:51: Sweet talk! Kevin introduces the first installment of the journal’s “Classics in Diabetes” series. This new format brings timeless articles into the spotlight and showcases their value for today’s scientists. The first installment, “GPCR Promiscuity Reshapes Islet Physiology” (https://doi.org/10.2337/dbi23-0014), was co-authored by Diabetes Associate Editor Jonathan Campbell and Frans Schuit and appears in the September 2023 issue of the journal. This commentary explores the work of Dr. Schuit, its implications for the understanding of diabetes, and how it laid the foundation for a rethinking of a traditional role of glucagon. Here, in this enlightening discussion, Dr. Schuit takes us through the historical context that led to the hypothesis and conclusions of his January 1998 classic, “Dual Glucagon Recognition by Pancreatic β-Cells via Glucagon and Glucagon-Like Peptide 1 Receptors” (https://doi.org/10.2337/diab.47.1.66), and Dr. Campbell explains how rediscovering the concepts and findings of Dr. Schuit’s work has informed his current research. Drs. Schuit and Campbell conclude the discussion by sharing their thoughts on glucagon research and diabetes treatment.
