Analysis of the study, conducted in China between 2002 and 2006, is ongoing, but researchers based at Vanderbilt University and the Shanghai Institute of Preventive Medicine report data from the first four years of follow-up (total follow-up was five years) in the current issue of the Journal of the American Medical Association. The 5,042 women enrolled in the study were all breast-cancer survivors, ages 20 to 75, and they consumed soy from naturally occurring sources, such as tofu or soybeans; none of the women took soy supplements. They fell into two groups based on soy intake...
...rumblings over the mammography message provide a useful window into why U.S. health policy does not always dovetail with the best available medical evidence, and certainly not with the best available data on costs. By and large, American patients (not to mention politicians and cancer advocacy groups) still subscribe to the view that every life is worth saving, no matter the cost, and that when it comes to prevention, screening is always good and more is always better. For decades, patients have been steeped in the notion that frequent screening is not just beneficial but also essential to the early...
...impossible to say how frequently such "overdiagnosis" occurs, according to the task force, but the data did conclusively show that in order to save the life of one woman in her 40s from breast cancer, 1,904 women would have to be screened every year for up to 20 years. Because it judged that the risks of harm from annual screening outweighed the benefits, the panel issued its controversial recommendation that most women ages 40 to 49 need not get routine mammograms. "We felt that women would be better served if they understood the trade-off between the benefits, harms...
...Labor issues are compounded by environmental concerns voiced by international academics. The Australia-based Mineral Policy Institute believes that Ramu NiCo's assurances about mine-waste disposal in the Basamuk Bay not poisoning the fish-rich waters are based on "fatally flawed" data. (Other Chinese companies have been accused of importing vast amounts of illegal timber from P.N.G.'s dwindling forests, even as Beijing tries to protect its own natural bounty by cracking down on illicit logging at home.) "With other countries, we try to make foreign companies accountable by lobbying shareholders or raising public awareness in that country," says...
...divided into two groups—particles and forces—and that these two groups are constantly at work changing the dynamics of the universe. As part of this universe, human beings are also a composition of both forces and particles; hypothetically, if one could gather all the data on all the forces and particles in existence and learn all the laws of interaction that govern them, it would be possible to calculate exactly how these particles and forces interact in an equation that would proceed until the end of time. Discerning the events of the past, future...
