Elevated homocysteine levels have been associated with atherosclerosis. Folic acid supplementation is a simple, inexpensive way to reduce homocysteine levels, which has become popular for secondary prevention in patients with coronary artery disease (CAD), despite a paucity of long-term clinical trial data. Thus, Liem and colleagues studied 593 patients with stable CAD on statins who were randomized to open-label folic acid 0.5 mg/d or standard care, which included aggressive pursuit of lipid goals.

Serum prostate-specific antigen (PSA) testing is frequently used in early detection programs for prostate cancer. While PSA testing has resulted in an increase in prostate cancer detection, its routine use has been questioned because of a lack of specificity. The objective of this study was to determine whether year-to-year fluctuations in prostate-specific antigen levels are due to natural variation and render a single PSA test result unreliable.
