Marc Lipsitch, an epidemiologist at the Harvard School of Public Health, and his colleagues studied the course of the 2009 H1N1 pandemic last spring in two cities - New York and Minneapolis - and determined that 0.048% of people who developed symptoms of H1N1 died, and 1.44% required hospitalization. Based on that data, published in PLoS Medicine, Lipsitch anticipates far fewer deaths from 2009 H1N1 than was initially believed. By the end of the flu season in the spring of 2010, Lipsitch predicts, anywhere from 6,000 to 45,000 people will have died from H1N1 in the U.S., with the number...
...risks: a 10.3% risk of death from breast cancer and an 11.2% risk of recurrence. "I think based on our study, I am quite comfortable saying that soy food, particularly a moderate amount, is safe, and potentially beneficial," says the study's lead author, Dr. Xiao-Ou Shu, an epidemiologist at Vanderbilt...
...another spike later in the year, during the colder months of winter - and it could be more severe, as has occurred in past pandemics. "I think this was a wakeup call in terms of preparing for something which would have [worse] characteristics," said Arnold Monto, an epidemiologist at the University of Michigan School of Public Health...
...idea that environmental conditions in the womb may have lifelong effects on the fetus is certainly not new. British epidemiologist D.J. Barker first proposed his theory of fetal origins in 1992, arguing that when the fetus doesn't get enough nutrition in utero, for example, an increased risk of future heart disease and diabetes somehow gets "programmed" into his or her development. There wasn't very much data to back Barker's theory at the time, but over the decades, a wealth of animal and human data has suggested it's true. Maternal conditions like high blood pressure and diabetes...
...measuring the prevalence of a medical condition. "The fact that 40% of the parents reporting that their child had received an ASD diagnosis now say the child no longer met criteria does suggest that there may be over-reporting in this survey," says Craig Newschaffer, a leading autism epidemiologist at Drexel University School of Public Health. "Nonetheless, the survey reinforces what we have come to understand over the past decade - that autism is much more common than previously thought."
