...human hosts. "Imagine a virus like AIDS that was transmitted by droplets in the air rather than sexually, and which led to death in months rather than years. In these circumstances we might not have time to study the disease before it ravaged cities," says Uwe Brinkmann, a Harvard epidemiologist...
...only 142 cases. In the highest exposure groups, the calculation for leukemia risk was based on as few as seven cases. In addition, the Swedes found no increase in malignancies of the brain. "Up to this point the evidence had been stronger for brain tumors," says David Savitz, an epidemiologist at the University of North Carolina...
...that many drugs are derivative of one another. For example, when bacteria developed an enzyme to chew up penicillin, drug designers retaliated with larger antibiotic molecules that did not fit into the site that serves as that enzyme's "mouth." In short order, says Dr. Mitchell Cohen, an epidemiologist at the U.S. Centers for Disease Control, "the bacteria responded to the challenge by developing an enzyme with a bigger mouth...
Researchers have worked for years to figure out why it is so dangerous to be born black in America; two new medical studies reveal the extent of the devastation. Writing in the New England Journal of Medicine, Dr. Kenneth Schoendorf, a medical epidemiologist at the National Center for Health Statistics, reported that black babies suffered twice the mortality rate of white infants even when both parents had completed college. Based on U.S. birth and infant death certificates that were filed from 1983 to 1985, a determination was made by Schoendorf and his colleagues that the gap was due entirely...
...epidemiologist Richard Peto, researchers at Oxford University pooled together the raw data from 133 studies conducted around the world on 75,000 women with operable breast cancer over the past four decades. Using a complex and unusual statistical process, they found that for women with early cancer, tamoxifen boosted 10-year survival rates from 71% to 75%. Although that kind of advance seems incremental, it translates into tens of thousands of lives each year...
