Parasite Evades Death by Promoting Host Cell Survival

Researchers have discovered how the parasite Trypanosoma cruzi, which causes Chagas’ disease, prolongs its survival in infected cells. A protein on the parasite activates the enzyme Akt, which blocks cell death signals, preventing cell destruction and parasite elimination. Chagas’ disease affects some 8 to 11 million people throughout Latin America and even the United States.

H1N1 More Risky than Seasonal Flu in Children with Sickle Cell Disease

Infection with the H1N1 virus, or swine flu, causes more life-threatening complications than seasonal flu in children with sickle cell disease, according to research from Johns Hopkins Children’s Center. The findings, to be presented on Dec. 7 at the annual meeting of the American Society of Hematology, warn parents and caregivers that such children are more likely to need emergency treatment and stays in an intensive-care unit.

Why Some Monkeys Don’t Get AIDS

Two studies published this month in the Journal of Clinical Investigation provide a significant advance in understanding how some species of monkeys such as sooty mangabeys and African green monkeys avoid AIDS when infected with SIV, the simian equivalent of HIV.

Seasonal Flu Shot Awareness High in Hispanics, Vaccination Rates Lower

Although there is high awareness of the need for seasonal influenza vaccines, a new study of Hispanics in one California county shows low rates of actual vaccination, especially among men.

New Clues Into How Invasive Parasite Spreads

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a possible strategy against an invasive parasite that infects more than a quarter of the world’s population, including 50 million Americans.

New Drug Technology Produces Marked Improvement in Hepatitis C Therapy in Animals; May be Useful for Wide Range of Diseases

In a dramatic finding, a new drug for hepatitis C virus (HCV) infections that targets liver cells produced a substantial drop in blood levels of the virus in animals and continued to work up to several months after treatment, say scientists at the Southwest Foundation for Biomedical Research (SFBR) in San Antonio.

'Late Preterm' Infants Remain at Risk of Bloodstream Infection

Sepsis is a serious infection that is a major cause of death in very premature infants. But sepsis is also a threat in "late preterm" infants born just a few weeks prematurely, according to a study in the December issue of The Pediatric Infectious Disease Journal.
