Today's Vidyya contains some news about the popular DASH diet. The blood pressure-lowering DASH diet also reduces levels of the amino acid homocysteine, according to a National Heart, Lung, and Blood Institute (NHLBI)-funded study. As health care practitioners are aware, a high level of homocysteine appears to increase the risk of heart disease, stroke, and peripheral vascular disease. We have a summary of the study for you. The full study appears in the August 22 issue of Circulation: Journal of the American Heart Association.
There's some bad news about the X-ray. In two unrelated studies, researchers have found that women with scoliosis, or abnormal curvature of the spine, who were exposed to multiple diagnostic X-rays during childhood and adolescence may be at increased risk of dying of breast cancer and that X-ray follow-up of persons with lung cancer has no therapeutic benefit. The first study appears in the 15 August 2000 issue of the journal Spine. The second appears in appears in the Journal of the National Cancer Institute, Vol. 92,
No. 16, 16 August 2000.
This issue also contains an update on the STAR (Study of Tamoxifen and Raloxifene) breast cancer trial. Agencies are busy looking for participants. So far 47,000 women have been interviewed and over 6,000 have been enlisted. The trial is looking for 16,000 more women.
Finally, we've included a new report released this week from the National Institute for Mental Health (NIMH). The study takes an in-depth look at the available assessment tools for evaluating suicidal behavior in children and adolescents. The report is important as there is an increased awareness of suicidality as a problem, and because completed suicide is the third leading cause of death among young people. Efforts to identify youths who have engaged in suicidal behaviors or are at high risk for engaging in
suicidal behavior have increased markedly over the last years with no consensus on the best way to detect and help those at risk. This 202 page report makes an attempt to sort and evaluate current methods.
