A study involving almost 2,400 women has shown that a vaccine that prevents infection with one of the viruses linked to cervical cancer is generally safe and effective. In most of the world, cervical cancer is the second leading cause of cancer-related death among women.
Previous research has implicated oxidative damage (cell degradation) in the development of Parkinson’s disease. Because vitamins E, C and carotenoids are antioxidants, researchers recently studied the associations between their intake and risk of Parkinson’s disease. Their conclusions point not to supplements, but to dietary intake of vitamin E (from the foods we eat) as having a protective factor in the risk of developing Parkinson’s disease. The study is reported in the October 22 issue of Neurology, the scientific journal of the American Academy of Neurology.
Black Americans’ fruit and vegetable intake increased by 32 percent for each additional supermarket in the neighborhoods where they lived, according to a new University of North Carolina at Chapel Hill School of Public Health study. White Americans’ fruit and vegetable consumption increased by 11 percent with the presence of one or more supermarket in their neighborhoods, the study showed. “We don’t know why we saw a larger influence of supermarkets on the diets of black Americans compared to white Americans,” said Dr. Kimberly Morland of the Mt. Sinai School of Medicine. “Based on our previous research showing a lack of private transportation in predominately black neighborhoods, we suspect that white Americans may have a larger geographic area in which to select places to patronize.
In a 20-year follow-up study of mortality data on residents living within a five-mile radius of Three Mile Island (TMI), researchers at the University of Pittsburgh’s Graduate School of Public Health (GSPH) found no significant increase overall in deaths from cancer. “This survey of data, which covers the normal latency period for most cancers, confirms our earlier analysis that radioactivity released during the nuclear accident at TMI does not appear to have caused an overall increase in cancer deaths among residents of that area over the follow-up period, l979 to l998,” said Evelyn Talbott, Dr.P.H., professor of epidemiology at GSPH and principal investigator on the study.
