Cognitive behavioral therapy (CBT) and a program of physical and mental rehabilitation probably improve symptoms of long covid, but the effects are modest, finds a review of the latest evidence published by The BMJ today. Intermittent aerobic exercise also probably improves physical function compared with continuous aerobic exercise. But the researchers found no compelling evidence to support the…

Factors beyond carbohydrates have a substantial influence on blood glucose levels meaning current automated insulin delivery systems miss vital information required for glucose regulation, a new study has found. A team of researchers from the University of Bristol analyzing automated insulin delivery data from people with Type 1 Diabetes (T1D) discovered that unexpected patterns in…

A large new population study of men over 45 indicates insulin resistance may be an important risk factor for the development of the world's most common heart valve disease – aortic stenosis (AS).  Published today in the peer-reviewed journal Annals of Medicine, the findings are believed to be the first to highlight this previously unrecognised…
