Study examines calorie restriction and glycemic load

The first phase of a caloric restriction study in human subjects at the Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University found evidence suggesting that calorie-restricted diets differing substantially in glycemic load can result in comparable long-term weight loss. The study, part of the multi-center Comprehensive Assessment of Long-term Effects of Restricting Intake of Energy (CALERIE) trial, funded by the National Institute on Aging, accounted for dietary factors that affect hunger and satiety, used laboratory techniques to measure adherence, and was the first of its kind to provide a complete set of meals and snacks to its participants. Recruitment is currently underway for participation in the second phase of the CALERIE study at Tufts, which will examine the relationship between calorie-restricted diets, aging, and age-related disease. more  

Many women undertreated for ovarian cancer

One in three ovarian cancer patients in the U.S. fails to receive the recommended comprehensive surgical treatment, according to a study in the May 15, 2007 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study of hospital data from nine states found that women who were over 70, of African American or Hispanic race, or insured by Medicaid, were at greatest risk for undertreatment. In addition, women treated by non-gynecological oncologists, by surgeons who perform few ovarian cancer surgeries, and at facilities that perform fewer than 10 procedures per year were less likely to receive recommended surgical care. more

Research explores herbal treatment for recurring urinary tract infections

A common herbal extract available in health food stores can greatly reduce urinary tract infections and could potentially enhance the ability of antibiotics to kill the bacteria that cause 90 percent of infections in the bladder. more  

Partners of cancer survivors at risk for depression

A new study shows that partners of cancer survivors are susceptible to the same stresses as cancer survivors themselves over the long term, and in some cases, suffer more quality of life-related effects than survivors. The results of the study, which examined partners of cancer survivors who had undergone blood and marrow transplant (BMT) as part of their treatment, are being published online April 10 in the Journal of Clinical Oncology (JCO). more

Neural biochemical levels increase with exercise  

Levels of a naturally-produced chemical that promotes brain health increase proportionally to the intensity of exercise, according to a joint research project between the Departments of Physiology and Health, Exercise, and Sport Sciences at Texas Tech. more

Heart-healthy behavior is a good news-bad news story  

Most Americans engage in behaviors that can help prevent or delay the onset of heart disease, according to the latest News and Numbers from the Agency for Healthcare Research and Quality. The good news is that over 93 percent of adults surveyed by AHRQ in 2004 reported that they engaged in at least one of the three heart-healthy behaviors recommended by the American Heart Association -- not smoking, exercising regularly, and maintaining a healthy weight. more
