Writing the first commentary for a new feature in the Journal of the American Medical Association (JAMA), called Viewpoint, Johns Hopkins cardiologists make the case for why a 55-year-old man with a 10 percent estimated risk of heart attack over the next 10 years should be offered statin medication. They were invited to debate a professor who argues against prescribing statins for "primary" prevention—for those who have not had a cardiovascular event, such as a heart attack—even though they may be considered at "intermediate" risk because of elevated cholesterol or other factors.

Reducing iron levels in blood plasma may protect brain from changes related to AD

Alzheimer's disease (AD) is now the sixth leading cause of death among Americans, affecting nearly 1 in 8 people over the age of 65. There is currently no treatment that alters the course of this disease. However, an increasing amount of evidence suggests that changes in the way the body handles iron and other metals like copper and zinc may start years before the onset of AD symptoms. A new study shows that reducing iron levels in blood plasma may protect the brain from changes related to AD.
