SCORED and SOLOIST trials add to evidence for treating diabetes with SGLT2 inhibitors

Less than a decade ago, the Food and Drug Administration approved drugs for treating type 2 diabetes in an entirely new way. Since that time, evidence in favor of the use of sodium/glucose cotransporter 2 (SGLT2) inhibitors has been mounting, with studies showing better blood glucose control, cardiovascular benefits, weight loss and more for patients with diabetes taking SGLT2 inhibitors. Now, two large clinical trials, conducted by investigators at Brigham and Women's Hospital and sponsored by Lexicon Pharmaceuticals, add new evidence about the benefits for patients with diabetes and chronic kidney disease as well as those with diabetes and recent worsening heart failure. In these two paired trials, teams of investigators led by Brigham cardiologist Deepak L. Bhatt, MD, MPH, evaluated sotagliflozin, a drug that inhibits SGLT2 and SGLT1. Results of the trials are both published in The New England Journal of Medicine and presented by Bhatt simultaneously at the Late-Breaking Clinical Trial Sessions of the American Heart Association Scientific Sessions.

Pesticides commonly used as flea treatments for pets are contaminating English rivers

Researchers at the University of Sussex have found widespread contamination of English rivers with two neurotoxic pesticides commonly used in veterinary flea products: fipronil and the neonicotinoid imidacloprid. The concentrations found often far exceeded accepted safe limits.

Trial shows drug effective in 96% of patients with recurrent pericarditis

Exercised over nothing: Masks don't impair lung function during physical activity

Wearing a facemask helps limit the spread of COVID-19 by reducing respiratory droplets and aerosols spewed into the air when people breathe, talk, laugh, sneeze or cough. But the physical barrier created by masks has prompted concerns that they might impair the cardiopulmonary system by making it harder to breathe, by altering the flow of inhaled oxygen and exhaled carbon dioxide and by increasing dyspnea—a medical term that describe shortness of breath or difficulty breathing, especially during physical activity.
