Coffee may impair peak heart function

In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude, according to a new study in the Jan. 17, 2006, issue of the Journal of the American College of Cardiology.

New pathways linking liver disease to changes in the central nervous system

Liver disease is often associated with "sickness behaviors," such as malaise, listlessness, anorexia, difficulty concentrating, and fatigue. In cholestatic liver diseases (where bile production is impaired) such as primary biliary cirrhosis, fatigue occurs in up to 86 percent of patients.

Women suffering lupus OK to take oral contraceptives

Major study of women with either inactive or stable systemic lupus erythematosus (lupus) – a disease in which the body's immune system mistakenly attacks and damages healthy tissues of the skin, joints and internal organs – were able to take oral contraceptives without increased risk of flares, or periods of increased disease activity, that characterize the disease.
