New NCI clinical trial program benefits people and pets
In the public perception, medical research involving animals is sometimes controversial and misunderstood. But a new program under the auspices of NCI's Center for Cancer Research (CCR) - the Comparative Oncology Program (COP) - may help change that view. "This program will provide pet owners with access to some very novel experimental options if their pet is stricken by cancer," says Dr. Robert Wiltrout, deputy director for science at CCR, "while also providing new information that may ultimately contribute to the treatment of cancer in humans."  more

Diabetes and cancer risk link not tied to obesity
A prospective cohort study of almost 1.3 million Korean men and women confirmed previous research showing a link between increased levels of fasting serum glucose and an increased risk of various types of cancer. The NCI-funded study, published in the January 11 Journal of the American Medical Association, noted the additional finding that the risk wasn't related to the subjects' body weights because the Korean study population was "far leaner than the Western populations in other studies."  more

CDC issues updated guidelines on use of antiretroviral drugs to prevent hiv infection after sexual, drug use, and accidental exposure
The Centers for Disease Control and Prevention (CDC), an agency of the Department of Health and Human Services, today announced new federal guidelines for the use of antiretroviral drugs to prevent HIV infection after exposure to HIV through sexual intercourse, sexual assault, injection drug use, or accidents.  more


MMWR reprint: Antiretroviral postexposure prophylaxis after sexual, injection-drug use, or other nonoccupational exposure to HIV in the United States: Recommendations from the U.S. Department of Health and Human Services
The most effective means of preventing human immunodeficiency virus (HIV) infection is preventing exposure. The provision of antiretroviral drugs to prevent HIV infection after unanticipated sexual or injection-drug–use exposure might be beneficial. The U.S. Department of Health and Human Services (DHHS) Working Group on Nonoccupational Postexposure Prophylaxis (nPEP) made the following recommendations for the United States. For persons seeking care < 72 hours after nonoccupational exposure to blood, genital secretions, or other potentially infectious body fluids of a person known to be HIV infected, when that exposure represents a substantial risk for transmission, a 28-day course of highly active antiretroviral therapy (HAART) is recommended. Antiretroviral medications should be initiated as soon as possible after exposure.  more

Men and women use different brain areas to achieve similar IQ results
While there are essentially no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence. more

Mouse brain cells rapidly recover after Alzheimer's plaques are cleared
Brain cells in a mouse model of Alzheimer's disease have surprised scientists with their ability to recuperate after the disorder's characteristic brain plaques are removed.  more

Cord blood transplantation now a viable option for adult leukemia patients
Stem cell transplantation using umbilical cord blood is a standard treatment option for blood disorders in children, but not for adults, due to the difficulty of obtaining a sufficiently large dose of cells. To solve this problem, researchers from the University of Minnesota examined a new technique that combines two cord blood units from different donors for transplantation into adult or adolescent leukemia patients. more
