Among patients with a previous stroke, reducing levels of the amino acid homocysteine (thought to contribute to heart disease) in the blood with high-dose vitamin therapy does not reduce the risk for recurrent stroke, heart disease or death, according to a study in the February 4 issue of The Journal of the American Medical Association (JAMA).

A study of more than 100,000 screening mammograms acquired at a large academic practice and interpreted either with or without the results of a computer-aided detection system has found that computer-aided detection does not change either the recall rate or breast cancer detection rate compared with mammograms interpreted without a computerized detection system.
