Study: Exercise painful for peripheral artery disease patients, but beneficial
By (0)
Fast-paced walking is painful for the millions of people with peripheral artery disease. But new research shows that a slower, pain-free pace won t cut it if improvement in mobility is the goal.
The study included more than 300 of the roughly 8.5 million Americans with PAD. It s a condition in which plaque build-up in arteries slows the flow of blood to the legs.
Advertisement People with PAD can typically walk only a couple of blocks before they have to stop and rest, said study author Dr. Mary McDermott, a professor at Northwestern University Feinberg School of Medicine, in Chicago.

Severe allergic reactions to COVID-19 vaccines are rare and resolve quickly, a new study finds. The COVID-19 mRNA vaccines are the first vaccines of their kind, and they have remarkable efficacy and safety across all populations, said lead researcher Dr. Kimberly Blumenthal.
Advertisement It is critical to have accurate information on allergic reactions to these vaccines, not only for our current situation, but also because this new vaccine platform is so important for future pandemic responses, said Blumenthal, co-director of the Clinical Epidemiology Program at Massachusetts General Hospital s Division of Rheumatology, Allergy and Immunology.

Cancer survivors are at greater risk of developing another cancer and dying from it, a new study finds.
These new cancers can result from a genetic predisposition, from treatments such as radiation and chemotherapy used to fight the first cancer, as well as from unhealthy lifestyles such as smoking and obesity, according to researchers from the American Cancer Society.

Some of these factors can t be controlled, but others can, noted lead researcher Dr. Ahmedin Jemal, a senior vice president at the society.
Getting a high-dose flu shot instead of a regular dose doesn't further reduce the risk of serious flu-complications, hospitalization or death in people with heart disease, new research shows.
