Medscape Medical News    Share   Share on FacebookTwitterShare on LinkedinE-mail
Approximately 4 percent of health care workers tested positive for methicillin-resistant Staphylococcus aureus (MRSA) in a large screening effort, a new analysis reports. Carlos Guerra, MD, from the Brody School of Medicine at East Carolina University in Greenville, N.C., presented the findings at the Fifth Decennial International Conference on Healthcare-Associated Infections 2010. The researchers sought to determine the prevalence and genotypes of MRSA isolates from various groups of health care workers, and to evaluate the effectiveness of eradication therapy with nasal mupirocin.

Blood test may predict rheumatoid arthritis
WebMD Health News via Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Elevated levels of inflammatory proteins called cytokines and related factors in the blood may be an early warning sign of impending rheumatoid arthritis, according to a new study. Researchers have found that levels of certain cytokines and related factors in the blood increase significantly prior to the development of rheumatoid arthritis, long before symptoms emerge. They say the finding paves the way for developing a blood test for early diagnosis of the mysterious disease. More

WHO admits shortcomings in handling flu pandemic
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail
Keiji Fukuda, the WHO's top influenza expert, said the U.N. agency's six-phase system for declaring a pandemic had sown confusion about the flu bug which was ultimately not as deadly as the widely-feared avian influenza. "The reality is there is a huge amount of uncertainty (in a pandemic). I think we did not convey the uncertainty. That was interpreted by many as a non-transparent process," Fukuda said. More

Viruses harnessed to split water
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth. In this case, the team used a modified virus as a kind of biological scaffold that can assemble the nanoscale components needed to split a water molecule into hydrogen and oxygen atoms. Splitting water is one way to solve the basic problem of solar energy: It's only available when the sun shines. More

In blood debate, new consent effort aims to open research doors
The Detroit Free Press    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It's unclear what health secrets may be locked in millions of dime-sized, rust-colored blood spots of nearly every Michigander born since July 1984. Now, scientists may have the chance to find out. The Michigan Department of Community Health is opening to researchers its archive of blood spots taken from every baby born in Michigan in the last 26 years — information stored on more than 4 million index cards at Wayne State University's TechTown. In addition to research on the old samples, the department is hoping to make available the blood of new babies, too. More
