Back Pain :: Psychological treatments improve back pain
Psychological interventions for chronic low back pain are effective, a new review of studies has found. Not only do these approaches improve psychological outcomes such as depression and health-related quality of life, they also reduce patients’ experience of pain.
Gene :: Studying genetic traits of India-born populations in US
Researchers conducting genetic analysis of India-born individuals in the US may have begun to shed light on the genetic variations of the diverse population of India.
Healthcare :: Clinical simulation technology used to improve communication of medical teams
The Institute of Medicine estimates that medical errors are the eighth leading cause of death in the United States, and poor communication can be a major source of those errors. Now the Clinical Simulation Center at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis hopes to improve patient safety by using clinical simulators to find the source of miscommunications during medical treatments.
Alzheimer’s Disease :: New brain imaging compound shows promise for earlier detection of Alzheimer’s Disease
A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer’s disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine.
Gene :: Human and chimp genes 6% unique
Approximately six per cent of human and chimp genes are unique to those species, report scientists from the University of Bristol and three other institutions.
Prostate Cancer :: Prostate cancer treatment costly $42,570
A new study reveals that the cumulative cost of prostate cancer is, on average, $42,570 over five years. Watchful waiting was the least expensive treatment while radiation and androgen deprivation therapy were the most expensive.
Aging :: Exercise enhances seniors’ physical, mental functioning
For older Americans, reversal of the brain shrinkage that occurs as people age is just one benefit of greater physical activity, according to research published in the latest issue of the Journal of Gerontology — Medical Sciences (Vol. 61A, No. 11). In a special section devoted to exercising and aging, this edition of the journal features five separate reports on the topic.
Contraception :: Male contraception pill from sperm’s tail protein
In a study recently published online by Developmental Biology, members of Dr. John Herr’s laboratory at the University of Virginia Health System report the discovery of a new protein within a sperm’s tail that could prove a key target for male contraceptive drugs.
Restless Legs Syndrome :: Requip, ropinirole treatment for restless legs syndrome
Newly approved medications for restless leg syndrome may only be effective for a time, suggest movement disorder neurologists from the University of Rochester Medical Center. If taken too long, in some cases the drugs can actually backfire, causing symptoms to worsen. Rochester specials suggest that treatment that rotates through different types of medications may be needed for many patients.
