Dental visits usually result in patient recommendations to floss or reschedule more appointments to treat a cavity, however, some patients are learning they may be at risk for a stroke too, according to a case report in the November/December issue of General Dentistry, the Academy of General Dentistry's (AGD) clinical, peer-reviewed journal.  more

Brain can be trained to process sound in alternate way, study shows
UCSF scientists have found that the brains of rats can be trained to learn an alternate way of processing changes in the loudness of sound. The discovery, they say, has potential for the treatment of hearing loss, autism, and other sensory disabilities in humans. It also gives clues, they say, about the process of learning and the way we perceive the world.  more

AHRQ issues new report on the safety and effectiveness of melatonin supplements
A new evidence review by HHS' Agency for Healthcare Research and Quality found that melatonin supplements, which people often take for problems sleeping, appear to be safe when used over a period of days or weeks, at relatively high doses and in various formulations. However, the safety of melatonin supplements used over months or even years is unclear. While there is some evidence for benefits of melatonin supplements, for most sleep disorders the authors found evidence suggesting limited or no benefits. But the authors say that firm conclusions cannot be drawn until more research is conducted. more

Melatonin for treatment of sleep disorders - AHRQ summary evidence report/technology assessment: Number 108
In this report, AHRQ sponsored researchers reviewed the use of melatonin for the treatment of a number of categories of sleep disorders, including primary sleep disorders, secondary sleep disorders, and sleep restriction, in a number of different populations. They reviewed not only the safety and effectiveness of melatonin for the treatment of sleep disorders, but also the pharmacology of exogenous melatonin and the physiology of endogenous melatonin, to provide a comprehensive overview of the state of research in this area. more

Molecular test predicts risk of breast cancer recurrence and who will benefit from chemotherapy
A new test can predict both the risk of breast cancer recurrence and may identify women who will benefit most from chemotherapy, according to research supported by the National Cancer Institute (NCI), part of the National Institutes of Health, and performed in collaboration with the National Surgical Adjuvant Breast and Bowel Project (NSABP) and Genomic Health Inc. These results suggest that almost half of over 50,000 U.S. women diagnosed with estrogen-dependent, lymph-node negative breast cancer* every year are at low risk for recurrence and may not need to go through the discomfort and side effects of chemotherapy. more
