Bloodstream pathogens
Clinical Laboratory News    Share   Share on FacebookTwitterShare on LinkedinE-mail article
Every year in the U. S., 350,000 patients acquire bloodstream infections while in the hospital, resulting in more than 90,000 deaths and significant costs to the health care system. Rapidly detecting and identifying the infectious pathogens is therefore critical for favorable patient outcomes. However, blood culture, the gold standard for diagnosis of bloodstream infections, often takes several days. More



Early treatment with anti-HIV drugs stops transmission between partners
Time magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail
article
Researchers report yet more tantalizing data that the antiretroviral drugs doctors currently use to treat HIV infection could also be effective in preventing transmission of the virus. In a large randomized trial involving more than 1,700 heterosexual couples — in which one person was HIV-positive and the other was not — infected people who took the anti-HIV drugs reduced their risk of transmitting the virus to their partners by 96 percent, compared with those who did not immediately start treatment.

Introducing the JAMA Clinical Challenge
Journal of the American Medical Association    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Journal of the American Medical Association (JAMA) introduces a new feature, the JAMA Clinical Challenge. The goal of this section is to provide clinical images that reflect visual findings that a clinician might encounter in the office setting. Synthesizing the visual information might not always result in an instant diagnosis of a problem, and therefore the key question in this feature is "What would you do next?" More

Setback for new stem cell treatment
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In an unexpected setback to efforts to harness a promising new type of stem cell to treat diseases, researchers reported that tissues made from those stem cells might be rejected by a patient's immune system — even though the tissues would be derived from the same patient. The research involved so-called induced pluripotent stem cells, or iPS cells, which can be made from skin cells and which appear to have the characteristics of embryonic stem cells. More

Hydroxycarbamide may help babies with sickle cell anemia
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Hydroxycarbamide can be considered for treatment of all very young children with sickle cell anemia, according to the results of a randomized, double-blind trial reported in The Lancet. "Sickle cell anaemia is associated with substantial morbidity from acute complications and organ dysfunction beginning in the first year of life," wrote Winfred C. Wang, from St. Jude Children's Research Hospital in Memphis, Tenn. "Hydroxycarbamide substantially reduces episodes of pain and acute chest syndrome, admissions to hospital, and transfusions in adults with sickle cell anaemia." More



Worm regenerates a whole new body from a single cell
Popular Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
One cell is all it takes to rebuild a complete, functioning flatworm, researchers have learned. The animals possess a special type of cell throughout their bodies, which shares some qualities with human embryonic stem cells. If scientists can find out how this special cell works, they could someday study ways to use the cells for human tissue regeneration. More
