...much harm wasn't clear until last week, when a team of scientists at Columbia University reported in the journal Radiology precisely how much radiation you are exposed to in a single full-body scan. It turns out to be 100 times the radiation dose of a typical mammogram--or roughly equivalent to that received by Hiroshima survivors 1.5 miles away from the center of the atom bomb blast. According to David Brenner, lead author of the study, the risks associated with just one scan are relatively modest, likely to increase your chances of dying from a radiation-caused cancer...
...trial of the cholesterol-lowering statin drug Lipitor last March found that high doses lowered patients' levels of LDL (the "bad" cholesterol) and also reduced their heart-attack risk. That's why the results of a new study on similarly high doses of the statin Zocor are so disappointing. In the 4,500patient study, published online by the Journal of the American Medical Association, patients taking high doses of Zocor fared no better than a low-dose group in terms of heart-attack risk, despite low LDL levels. Why? Perhaps because Lipitor works not just by lowering cholesterol but also...
Days on Nair's set, populated by longtime collaborators, begin with group yoga, which is followed by a healthy dose of ribbing by the director. "I directed Gabriel Byrne entirely in a Ugandan accent," she says proudly. How will her move into more mainstream films affect this familial way of working? Nair isn't too apprehensive. "When I have passion for something," she says, "I'm a weirdly kind of fearless person...
Johnston doesn't dwell on what age has taken away from her. "She's never been a complainer," says Julie. That attitude may have much to do with her prodigious longevity. Not to mention good genes and a whopping dose of good luck. Johnston's father, a Presbyterian minister, died at 69, her mother at 85. Her younger sister Vern died in 1997 at 105. Though Johnston had surgery for breast cancer in her 90s and a heart attack so minor she never noticed it, she has generally enjoyed superb health...
...codes on commonly used prescription drugs. Hospitals using this technology provide patients with identification bracelets that have a scannable bar code. Before dispensing any medication, a nurse scans both the patient's bar code and the drug's bar code to verify that the patient is getting the right dose of the right drug. Hospitals have two years to comply with these regulations...
