Study Looks At HIV, Risk Behaviors Among Male Clients Of Sex Workers In Tijuana, Mexico
"A large percentage" of U.S. and Mexican men who regularly engage in sexual activity with sex workers in Tijuana, Mexico, do not use condoms and have a history of substance and alcohol use, according to a study published in the online journal AIDS, the Los Angeles Times" blog "L.A. Now" reports. The study, by researchers from Mexico and the University of California-San Diego, surveyed 400 men - both Mexico and U.S. residents - and found that half of the men had unprotected sex with a female sex worker within the last four months. Researchers noted that although Tijuana authorities require that sex workers be registered and tested regularly for HIV, "only about half of [sex workers] have registered or been tested," according to the blog. Thomas Patterson of the UC-San Diego"s department of psychiatry and the Veterans Affairs health center, said the findings indicate a need for an educational campaign targeting men who frequent sex workers (Perry, 7/11).

Impact Of Medicare Part D On Medical Spending Addressed By NEJM Study
After enrolling in Medicare Part D, seniors who previously had limited or no drug coverage spent more on prescriptions and less on other medical care services such as hospitalizations and visits to the doctor"s office, according to a University of Pittsburgh Graduate School of Public Health study. Published in the July 2 issue of the New England Journal of Medicine, the study also found that seniors who had relatively good drug benefits prior to enrolling in Medicare Part D spent somewhat more on prescriptions and, at the same time, increased their spending on other medical care services.

Roswell Park Awarded $2.8 Million Grant To Study Ovarian Cancer

The National Cancer Institute has awarded a five-year, $2.8 million Research Project (RO1) grant to Roswell Park Cancer Institute http://www.roswellpark.org/ (RPCI) researchers to investigate the role of immunological pathways in the development of ovarian cancer. Roswell Park investigators are Kirsten Moysich, PhD , Division of Cancer Prevention and Population Sciences; Kunle Odunsi, MD, PhD , Department of Gynecologic Oncology; and Lara Sucheston, PhD, Assistant Professor of Biostatistics, University at Buffalo. "The coveted RO1 grants support individual scientists whose grant applications, after stringent peer review, have demonstrated outstanding science," said Candace Johnson, PhD, Deputy Director and the Wallace Family Chair in Translational Research, RPCI. "Roswell Park donations were critical in helping us initiate this research to generate novel preliminary data needed for our successful submission." While the causes of ovarian cancer remain largely unknown, scientific studies have consistently linked high regulatory T-cell levels to cancer. Unlike so-called effector T cells that attack foreign substances in the body, regulatory T cells actually suppress an immune reaction. Roswell Park scientists will, for the first time, conduct a comprehensive investigation of the role of regulatory T cells in ovarian cancer development and prognosis. Using a population-based case control study, Roswell Park scientists will compare regulatory T-cell levels in women diagnosed with ovarian cancer with those of healthy women. The research will help determine if women with ovarian cancer have higher blood regulatory T-cell levels than healthy women and if ovarian cancer patients with genetically determined high regulatory T-cell profiles have poorer clinical outcomes. "These data will be useful in the development of novel treatment options for ovarian cancer. Manipulation of regulatory T cells may afford a novel method to stimulate an immune response to this deadly disease. Additionally, physicians may find information concerning regulatory T-cell levels a useful tool as they evaluate the best treatments for their patients," said Dr. Moysich. Ovarian cancer is the leading cause of death from gynecological malignancies and the second most common gynecological cancer in the US. In 2009, an estimated 21,550 women will be diagnosed and 14,600 women will die from ovarian cancer. Roswell Park Cancer Institute
