Colleagues from the Brigham’s Center for Adrenal Disorders assessed the efficacy of aldosterone antagonism with a mineralocorticoid receptor (MR) antagonist versus placebo in patients with primary hyperparathyroidism (P-HPT). They provide evidence that MR antagonists have no meaningful role in P‐HPT treatment.

The “glycemic gap” has previously been validated as a predictor of severe acute illness. Now, Brigham and Women’s Hospital researchers have extended the glycemic index’s utility to COVID-19.


Vitamin D Supplementation Does Not Influence Fracture Risk in the General Population

To address conflicting evidence, Meryl S. LeBoff, MD, JoAnn E. Manson, MD, PhD, MPH, and colleagues conducted an ancillary analysis of the Vitamin D and Omega-3 Trial (VITAL). They found vitamin D did not affect fracture risk in the general population.


Roux-en-Y Gastric Bypass May Not Be As Safe As Sleeve Gastrectomy for Black and Latino/a/x Patients

Caroline M. Apovian, MD, and team determined that the variability of weight loss and hemoglobin A1C across racial/ethnic groups was small after Roux-en-Y gastric bypass (RYGB) compared with sleeve gastrectomy (SG). However, safety concerns were greater for Black and Latino patients after RYGB than SG.


Can a Fatty Acid Supplement Improve Outcomes in People With Obesity and Prediabetes?

Brigham researchers are looking at novel ways to boost natural mechanisms that the body uses to counteract the pathogenesis of obesity and its complications. An upcoming clinical trial led by Mehmet Furkan Burak, MD, explores the impact of dietary supplementation with palmitoleic acid in obese, prediabetic individuals.


Dapagliflozin Efficacious, Safe in Type 2 Diabetes Regardless of Pre-Treatment Systolic BP

SGLT2 inhibitors like dapagliflozin reduce hospitalization for heart failure and progression of diabetic nephropathy in patients with type 2 diabetes, but decrease systolic and diastolic blood pressure only minimally. Brigham researchers investigated whether their efficacy might depend on pre-treatment blood pressure.
