Study finds bacteria in milk linked to rheumatoid arthritis

A strain of common bacteria in milk and beef may be a trigger for developing rheumatoid arthritis in people who are genetically at risk, according to a new study from the University of Central Florida. A team of UCF College of Medicine researchers has discovered a link between rheumatoid arthritis and Mycobacterium avium subspecies paratuberculosis, known as MAP, a bacteria found in cows. The bacteria can be spread to humans through the consumption of infected milk, beef and produce fertilized by cow manure. The UCF researchers are the first to report this connection between MAP and rheumatoid arthritis in a study published in the Frontiers in Cellular and Infection Microbiology journal this week. The study, funded in part by a $500,000 grant from the Florida Legislative, was a collaboration between Saleh Naser, UCF infectious disease specialist, Dr. Shazia Bég, rheumatologist at UCF’s […]

Proper exercise can reverse damage to aging hearts

Exercise can reverse damage to  aging hearts and help prevent risk of future heart failure — if it’s enough exercise, and if it’s begun in time, according to a new study by cardiologists at UT Southwestern and Texas Health Resources. To reap the most benefit, the exercise regimen should begin by late middle age (before age 65), when the heart apparently retains some plasticity and ability to remodel itself, according to the findings by researchers at the Institute for Exercise and Environmental Medicine (IEEM), which is a collaboration between UT Southwestern Medical Center and Texas Health Presbyterian Hospital Dallas. And the exercise needs to be performed four to five times a week. Two to three times a week was not enough, the researchers found in an earlier study. “Based on a series of studies performed by our team over the […]
