A clinical trial with adults who have atrial fibrillation (AFib) and an implanted heart device found similar improvements to the amount of time they experienced arrhythmia regardless of whether they received standard care (education pamphlets about healthy diet and exercise), followed a lifestyle/risk factor modification program, or took metformin and followed a lifestyle/risk factor modification program.

A study testing a new nasal spray form of the medication bumetanide, a commonly prescribed diuretic, was found to be as safe and well-tolerated (meaning with no significant nasal irritation) in healthy adults in comparison to the oral and intravenous forms of the medication. The existing oral and intravenous forms of bumetanide are commonly prescribed for people with heart failure because they ease tissue swelling, a common cause of symptoms for people with heart failure.

The SARAH trial included 114 adults with cancer undergoing chemotherapy at Erasto Gaertner, a cancer hospital in Curitiba, Brazil. 80.7% were being treated for breast cancer; 16.7 for leukemia; 1.7% for sarcoma and 0.9% for leukemia.
