...high number--and that 14% of these occurred in people with no documented history of a hospital stay. Because the CDC does not require physicians to report MRSA cases outside hospital settings, this report is the first to establish how prevalent the infections are, and, says Monina Klevens, an epidemiologist at the CDC, "It will be a baseline against which we can compare future numbers...
While the numbers may seem scary, this is the first time scientists have taken stock of the prevalence of MRSA in the U.S. "We are not interpreting these numbers as a rise in MRSA, because nothing like this has ever been done before," says Monina Klevens, a medical epidemiologist at CDC and lead author of the study. "It's a baseline against which we can compare future numbers. With the increased concern about community outbreaks of MRSA, we wanted to know how widespread the infections...
Recent studies have proved that statins not only control lipids, but are also potent regulators of inflammation - a key cause of lung deterioration. That's what led Joel Schwartz, an epidemiologist studying pollution and lung function, to examine the effects of statins. He and his colleagues looked at data on 803 subjects involved in the ongoing Veterans Administration Normative Aging Study, all of whom had their lung function measured in so-called spirometer-based breathing tests between 1995 and 2005. "It's interesting that we saw such a big effect here," Schwartz says. The statin users showed half the rate...
...protecting women in the past was that they had many children," says Dr. Vinod Raina, an oncologist in Delhi. Other researchers go even further, venturing to put a number on that claim. "Reproductive changes explain about 30% to 40% of breast-cancer threat," says Dr. Wei Zheng, an epidemiologist at Vanderbilt University in Nashville...
...women in the control group had both ovaries intact. Half of the women had oophorectomies because of a benign condition, such as infection or cysts, and the other half had their ovaries removed prophylactically to prevent ovarian cancer. Lead investigator Dr. Walter Rocca, a neurologist and epidemiologist at the Mayo Clinic in Minnesota, and his team found that compared with women who had kept both ovaries, the risk of cognitive impairment or dementia was doubled in women who had both ovaries removed before age 48 or one ovary removed before...
