Testing African couples for HIV is cost-effective prevention strategy

As researchers and policymakers work toward an effective HIV vaccine in a constrained global economy, cost-effective prevention strategies such as Couples Voluntary Counseling and Testing (CVCT) must take a larger role in efforts to decrease the rates of HIV/AIDS in Africa, says Emory University HIV/AIDS vaccine researcher Susan Allen, MD, MPH.

Allen, who has worked to combat the AIDS epidemic in Africa for more than 25 years, highlighted the value of CVCT and other cost-effective HIV prevention strategies today at the AIDS Vaccine 2010 Conference in Atlanta.

URI professor warns: TV viewing likely to make you fear sickness

What baby? 'Bioethicists' fault requirement that women in clinical drug trials use contraception

Research ethics review committees often require that all women of childbearing age who enroll in clinical trials use contraceptives to protect against a developing fetus being exposed to untested and therefore potentially harmful drugs.

A mandatory contraceptive policy is often imposed even when there is no evidence that a trial drug could harm a fetus or when women have no chance of becoming pregnant and a report in IRB: Ethics & Human Research says that isn't necessary.

CHAPEL HILL – Using the same technology found in clothing tags used in retail store tracking systems, a study from the University of North Carolina at Chapel Hill shows that surgical sponges with implanted radio frequency (RF) tags may be an effective adjunct to manual counting and X-ray detection in preventing sponges from being left behind in patients following a surgical procedure.

Age 50 as mammography screening threshold proven unfounded

The landmark breast cancer screening study of women 40-49, published online in Cancer, has proven that annual mammography screening of women in their 40s reduces the breast cancer death rate in these women by nearly 30 percent. The results of this largest study ever conducted on women in this age group confirm that the use of the age of 50 as a threshold for breast cancer screening is scientifically unfounded. Women should begin getting annual mammograms at age 40.

Scientists define molecular on-off switches for cancer and autoimmunity

A new report published in the October 2010 print issue of The FASEB Journal (http://www.fasebj.org) offers a ray of hope in the search for new cancer drugs. By examining the seemingly conflicting roles of how oncogenes and tumor suppressor genes handle cellular stress, scientists from the Institute for Advanced Studies in New Jersey argue that each of these opposing systems could be potent drug targets in the effort to stop cancer.
