U of M study: Online intervention paramount for reducing HIV in high-risk population

ST. PAUL / MINNEAPOLIS (April 29, 2008) – Young Internet-using men who have sex with men AND who meet their sexual partners both online and offline have greater numbers of partners, appear more likely to contract HIV, and report higher substance use rates than those who meet their partners exclusively online or offline, according to new research at the University of Minnesota.

Getting to the roots of breast cancer

The lesson learned in eradicating dandelions from your yard could apply in treating breast cancer as well, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the Journal of the National Cancer Institute.

“It’s not enough to kill the dandelion blossom and stalk that appear above ground,” said Dr. Michael Lewis, assistant professor of molecular and cellular biology and a faculty member in the Lester and Sue Smith Breast Cancer Center at BCM. “You have to kill the root beneath the soil as well.”

Selecting Patients Based on Genotype May Increase Efficacy of Tamoxifen

Breast cancer patients who carry the wild-type gene required for tamoxifen metabolism may have comparable risk of recurrence when taking tamoxifen or an aromatase inhibitor, according to modeling data.

Medicare costs estimated to top $21.1 billion for 5 years of care for elderly cancer patients

The cost of cancer care for elderly Medicare patients varies by tumor type, stage at diagnosis, phase of care, and survival, according to a new study published online April 29 in the Journal of the National Cancer Institute. The 5-year cost is highest for patients with lung, colorectal, and prostate cancers. The estimated cost for 5 years of care for elderly Medicare patients diagnosed with cancer in 2004 is $21.1 billion.

Review of cervical cancer screening program shows effectiveness and room for improvement

Women who do not undergo regular cervical cancer screening tests are more likely to be diagnosed with the disease than those who do, according to an audit of the Swedish national cervical cancer screening program that will be published online April 29 in the Journal of the National Cancer Institute. Participation in screening reduces the risk for all types of cervical cancers in all ages. Better follow-up of the women who are screened could further reduce cervical cancer rates, the researchers concluded.

Body image program reduces onset of obesity and eating disorders

In their research on eating disorders, Oregon Research Institute (ORI) scientists help young women reduce the influence of the “thin ideal,” which is described as associating success and happiness with being thin.

TAU researchers examine 'great expectations' in the workplace

Tel Aviv -- Researchers at Tel Aviv University have found that employee performance in the workplace, like students’ grades at school, is greatly influenced by managers’ expectations of that performance.

An analysis of results from twenty-five years’ worth of experimental research conducted at banks, schools, the Israel Defense Forces – and even summer camp – shows unequivocal results: when a leader expects subordinates to perform well, they do.

New whale detection buoys will help ships take the right way through marine habitat

Researchers from the Woods Hole Oceanographic Institution (WHOI) and the Bioacoustics Research Program (BRP) at the Cornell Lab of Ornithology have teamed up with an international energy company and federal regulators to listen for and help protect endangered North Atlantic right whales in New England waters.

Building on advances in ocean mooring design, underwater acoustic systems, and telecommunications, the team built and installed ten “auto-detection buoys” to listen for the calls of right whales along the main shipping lanes into Massachusetts Bay and Boston Harbor.

Too much technology may be killing beneficial bacteria

COLUMBIA, Mo. –Too much of a good thing could be harmful to the environment. For years, scientists have known about silver’s ability to kill harmful bacteria and, recently, have used this knowledge to create consumer products containing silver nanoparticles. Now, a University of Missouri researcher has found that silver nanoparticles also may destroy benign bacteria that are used to remove ammonia from wastewater treatment systems. The study was funded by a grant from the National Science Foundation.

Promising early evidence of the superior benefits of drug therapy for diabetic eye disease

April 29, 2008, New York, NY -- A JDRF collaboration between Johns Hopkins researchers and Genentech has shown that a drug for the treatment of diabetic eye disease has performed better in clinical trials than the current standard treatment using laser surgery.

These findings, representing the six-month end-point evaluation of the READ-2 clinical trial coordinated by The Johns Hopkins University, were presented Monday at the 2008 Annual Meeting of The Association for Research in Vision and Ophthalmology, in Fort Lauderdale, Florida.
