...abortion and a nearly threefold greater risk of ectopic pregnancy - a condition that accounts for about 9% of all pregnancy-related deaths in the U.S. "We were kind of concerned, and we wanted to either confirm or refute these previous findings," says Dr. Jun Zhang, a senior investigator and epidemiologist at the National Institute of Child Health and Human Development and co-author of the current study, because "the number of women who have had medical abortions is staggering both worldwide...
...study in the Aug. 15 issue of the Journal of the American Medical Association aims to clear up at least some of that uncertainty. Dr. Allan Hildesheim, an epidemiologist at the National Cancer Institute, and his colleagues set out to determine whether Cervarix - a new HPV vaccine for which GlaxoSmithKline hopes to get federal approval in early 2008 - could help reduce the virus-load in women already infected with HPV. According to the study's authors, past trials have suggested that HPV vaccination boosts the body's immune response to infection, and some researchers thought that it might work...
...first decade after cancer treatment. But "what we don't know is what happens to people as they age further out, 20 to 30 years beyond that," says Dr. Charles Sklar of Memorial Sloan-Kettering Cancer Center in New York City. To fill that gap, Hudson and St. Jude epidemiologist Les Robison are launching one of the most ambitious follow-up programs yet. They plan to contact 5,000 patients who have celebrated their 10-year survival anniversary and invite them to come back for free checkups for the rest of their lives. The program, like the hospital, is mainly...
...know that exercise can help prevent heart disease. But it was not always a closed case, at least not scientifically. In the 1960s, Harvard epidemiologist Dr. Ralph Paffenbarger Jr. set out to prove just that. In a pioneering study that tracked exercise and health, Paffenbarger and colleagues found that vigorous exercise could indeed lengthen life expectancy and combat chronic disease. Paffenbarger would also conclude that the benefits of exercise could be had even when starting late in life. The researcher practiced what he preached: at age 45, the once sedentary Paffenbarger, who died at 84, became a long-distance runner...
...simply don't have to. During the Depression, the government began subsidizing commodities like corn. Today, against all logic, the subsidies continue, and corn-derived snacks and Cokes are so cheap and convenient that, as University of Washington epidemiologist Adam Drewnowski argues, it's perfectly rational, on a dollar-per-calorie basis, to buy them. (Fresh fruits and vegetables aren't subsidized, and by nature they cost more to store and ship.) Drewnowski estimates it would cost 100 times as much to get the same amount of energy from fresh raspberries as from a typical packet of cookies...
