Annual arrival of new interns and residents might cause a transient increase of poor patient outcomes

Concern for patient safety, among other reasons, recently prompted sweeping changes in resident work policies in the United States. Recent studies have shown trends toward centralization of complex neurosurgical care at high-volume centers, which are often academic centers, and an increasing proportion of pediatric brain tumor surgeries being performed at teaching hospitals. Some have speculated that the annual arrival of new interns and residents at teaching hospitals in July might cause a transient increase of poor patient outcomes and inefficient care. more  

Treating chronic pain with DBS (deep brian stimulation)

Recent statistics indicate that one in five people worldwide suffer from moderate to severe chronic pain and that one in three are unable or less able to maintain an independent lifestyle due to their pain. Deep brain stimulation (DBS) has been used to treat chronic unresponsive pain for more than 50 years. There has been tremendous variability in the surgical techniques employed, regions of the brain stimulated, and painful conditions treated. This has been reflected in clinical outcomes, which have ranged from poor to excellent. more

18 million adults in China are obese

Around 18 million adults in China are obese, 137 million are overweight, and 64 million have metabolic syndrome—a condition where a number of risk factors for heart disease are present, suggests a study published in this week’s issue of The Lancet. more  

Pessimism and depression increase dementia risk

Individuals who do not have psychiatric problems but score very high on a personality test pessimism scale have a 30 percent increased risk of developing dementia several decades later. The same is true of individuals who score very high on the test’s depression scale. The risk is even higher -- 40 percent more -- for individuals who score very high on both anxiety and pessimism scales. more

Research could lead to new drugs for HIV 

The increased frequency of drug resistance in isolates of the AIDS virus, HIV, makes identification of new antiviral targets an urgent necessity. Host genes required to support the replication of HIV are a potential source of such novel targets, but relatively few appropriate target genes have been identified in animal cells thus far. A new study, conducted by Dr. Suzanne Sandmeyer and colleagues at the University of California, reports the discovery of over 100 host genes that affect the replication of a model retrovirus. Their results are reported in the May issue of Genome Research. more

Measuring enzymes at end of cancer pathway predicts outcome of Tarceva, Taxol 

Researchers at The University of Texas M. D. Anderson Cancer Center have developed a way to test whether the new targeted therapy Tarceva and the widely used chemotherapy drug Taxol are effectively killing tumor cells. They say that with further refinement, the test may make it possible to accurately assess whether patients are responding to these agents, as well as potentially others, within days of beginning therapy. more

Research urgently needed to treat blood clots in children

Potentially deadly blood clots are being missed in children, and more research and awareness is needed in the medical community, according to a study done in part at the University of Alberta. more
