Making a difference in five minutes—Interventions in diabetes for anyone

Saturday 8 June, 13:45–15:45. Room S-203, Moscone Center, San Francisco, California 

  1. Richard R. Rubin award lecture. Frank J. Snoek, PhD
  2. Overcoming psychological insulin resistance. William Polonsky, PhD, CDE

– Lori Berard, Nurse Consultant and Diabetes Educator

This session is 2 hours long, but each second should be worth it. All of us who deal with people living with diabetes will gain from the expert opinions presented here. Using insulin, ensuring adherence, achieving weight loss, and managing diabetes burnout will figure in this session. The speakers will provide insight which will help translate current knowledge into effective clinical practice.

Cardiovascular and renal protection in diabetes: emphasis on SGLT2 inhibitors and GLP-1 receptor agonists

Saturday June 8th, 13:45–15:45. Room B-Hall E, Moscone Center, San Francisco, California

  1. ​​​​​​​Renal effects of GLP-1 receptor agonists: from basic mechanisms to clinical data. Julie A. Lovshin, MD, PhD
  2. Cardiovascular effects of GLP-1 receptor agonists: From basic mechanisms to clinical data. Jens J. Holst, MD, DMSc

This session links directly to the recent ask the expert videos we produced with Dr Katherine Tuttle [Nephrologist and Endocrinologist], regarding the impact of renal impairment on cardiovascular disease. We should really be discussing "cardio-renal disease" rather than "cardiovascular disease".

Session recommendation

The Vitamin D and type 2 diabetes (D2d) study: A multicenter randomized controlled trial for diabetes prevention

Friday June 7th, 11:30–12:30. Room S157, Moscone Center, San Francisco, California

  1. Rationale and study design. Myrlene A. Staten, MD
  2. Recruitment, retention, and baseline characteristics. Erin S. Leblanc, MD, MPH
  3. Outcomes. Anastassios G. Pittas, MD, MS


The D2d trial is of particular interest due to a growing body of evidence which suggests that glucose and insulin metabolism may have farther-reaching effects on health and nutrition than previously thought. There now appears to be a greater understanding as to why so many patients with type 2 diabetes have vitamin D deficiency, and we need to determine if it's causative or as a result of insulin resistance​​​​​​​.

  5. What’s the role of nutrition in diabetes prevention? Christopher D. Gardner, PhD
  6. Translation to practice. Kelly M. Rawlings, MS

Ever-changing – always evolving – nutritional recommendation are one of the cornerstones of diabetes management. Evolving evidence of the benefit of different dietary patterns will help us to guide our patients in the healthy lifestyle behavior.

Paternal programming: I’m your papa

Friday 7 June, 14:00–16:00. Room S-157, Moscone Center, San Francisco, California

  1. Evidence and mechanisms for paternal epigenetic regulation of developmental origins of health and disease. Elvira Isganaitis, MD, MPH
  2. ​​​​​​​Obesity and bariatric surgery drive epigenetic variation of spermatozoa (human). Ida Donkin, MD, PhD
  3. Preconception diet or exercise intervention in obese fathers normalizes sperm microRNA profile and metabolic syndrome in female offspring (mouse). Nicole O. McPherson, PhD 
  4. Paternal long-term exercise programs offspring for low energy expenditure and increased risk for obesity in mice. P. Darrel Neufer, PhD
  5. Cold-induced epigenetic programming of the sperm enhances brown adipose tissue activity in the offspring (human and mouse). Christian Wolfrum, PhD


The session seems interesting for clinicians, educators and researchers. Findings discussed in talks at this symposium will stimulate us to view men as important contributors to the health of their offspring. A focus on pre-conception counselling in males should help us understand and address the epidemic of diabetes and other metabolic disease.
