A MRSA infection with a reduced susceptibility to the potent antibiotic drug vancomycin is linked to high mortality, according to a Henry Ford Hospital study.

Researchers found that patients who contracted a MRSA infection with heteroresistance, called hVISA, stayed in the hospital longer, were more likely to have the infection return after 90 days, and were twice as likely to die from it after 90 days than patients who do not have hVISA.

The study is being presented Sunday at the 50th annual Interscience Conference on Antimicrobial Agents and Chemotherapy in Boston.

An international team of scientists, led by researchers at the University of California, San Diego, has identified misfolding and other molecular anomalies in a key brain protein associated with autism spectrum disorders.

Graphene may hold key to speeding up DNA sequencing

Cambridge, Mass. - September 9, 2010 - In a paper published as the cover story of the September 9, 2010 Nature, researchers from Harvard University and MIT have demonstrated that graphene, a surprisingly robust planar sheet of carbon just one-atom thick, can act as an artificial membrane separating two liquid reservoirs.

 Making stem cells

For most people, wisdom teeth are not much more than an annoyance that eventually needs to be removed. However, a new study appearing in the September 17 Journal of Biological Chemistry shows that wisdom teeth contain a valuable reservoir of tissue for the creation of stem cells; thus, everyone might be carrying around his or her own personal stem-cell repository should he or she ever need some.

LAWRENCE — A drug developed at the University of Kansas has the potential to stop a debilitating condition of diabetes that often leads to pain in the extremities and even amputations, KU researchers have found.

The researchers recently published an article showing that KU-32 can stop and even reverse diabetic peripheral neuropathy, or DPN, in mice. The condition leads to death of nerves in the extremities of individuals with diabetes.

New Rochelle, NY, September 10, 2010—The glycome, encompassing all of the complex sugars produced by an organism, is comprised of multiple families of molecules whose function in the human body is often determined by the structure, composition, and placement of the attached sugars, as explored in a comprehensive look at the field of glycomics in a group of key articles in OMICS: A Journal of Integrative Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com).

X-rays are the medium of choice for many scientific studies. When you shine them on a sample, they literally shed light on the material's structure, providing loads of information about it. Unfortunately, this mostly applies to solids only, since the sample has to be in a vacuum for the entire time it is being irradiated with soft X-rays. For liquids, that means you have to remove all the water. In the case of biological samples such as proteins, however, this destroys their natural environment. The solution to this problems has always been to measure liquids through membranes.

Small intravenous devices (IVDs) commonly used in the hand or arm do not need to be moved routinely every 3 days. A randomized controlled trial comparing regular relocation with relocation on clinical indication, published in the open access journal BMC Medicine, found that rates of complications were the same for both regimens.

The renowned Journal of Biological Chemistry has selected the report of these research findings as one of two "papers of the week" for its September 10, 2010 issue and has chosen the structural model as cover image.

New York, NY, September 9, 2010 – The use of stem cells for research and their possible application in the treatment of disease are hotly debated topics.

Researchers from Mount Sinai School of Medicine have found that bisphenol A (BPA) released from some plastic resins used in pediatric dentistry is detectable in the saliva after placement in children's mouths. BPA is a widely used synthetic chemical that has been associated with changes in behavior, prostate and urinary tract development, and early onset of puberty. The findings are published in the current issue of Pediatrics.

Disparities in healthcare between races exist in the United States. A new study published in the journal Transfusion explores why African Americans donate blood at lower rates than whites. The findings reveal that there is a significant distrust in the healthcare system among the African American community, and African Americans who distrust hospitals are less likely to donate.

Researchers at the University of California, San Diego School of Medicine have identified "secondary over-triage" as a potential area of cost savings for our nation's health care. The phenomenon of over-triage occurs when patients are transferred twice, and discharged from a second facility in less than 24 hours. These findings will be published in the September 10th issue of The Journal of Trauma.

Diagnostic errors are the most important causes of avoidable harm to patients in hospitals, warns a senior doctor on bmj.com today.

Dr Gordon Caldwell, a consultant physician at Worthing Hospital in Western Sussex argues that doctors need better facilities and sufficient time to make a correct diagnosis.

When a patient is admitted to hospital, the team of doctors formulate a "working diagnosis," he explains. At this point, the diagnosis is uncertain but the patient is treated as if the working diagnosis is correct.
