Walking May Help Protect Kidney Patients Against Heart Disease and Infections

• In kidney disease patients, 30 minutes of walking improved the responsiveness of certain immune cells to a bacterial challenge and induced a systemic anti-inflammatory environment in the body. • Six months of regular walking reduced immune cell activation and markers of systemic inflammation.

Right now, options are limited for preventing heart attacks. However, the day may come when treatments target the heart attack gene, myeloid related protein-14 (MRP-14, also known as S100A9) and defang its ability to produce heart attack-inducing blood clots, a process referred to as thrombosis.

Study Shows Link Between HIV Infection and Coronary Artery Disease

Men with long-term HIV infections are at higher risk than uninfected men of developing plaque in their coronary arteries, regardless of their other risk factors for coronary artery disease, according to results of a study led by Johns Hopkins researchers. A report on the research appears in the April 1 issue of Annals of Internal Medicine.
