In older adults at risk for heart disease, a Mediterranean diet plus daily servings of mixed nuts may help manage metabolic syndrome, according to a Spanish study. Previous research suggests that a Mediterranean diet lowers the risk of abdominal obesity, high cholesterol, high blood pressure and high glucose levels -- all of which are risk factors for cardiovascular disease.
Mosquito-borne disease kills nearly 1 million people, mostly African children, every year. Results from two phase II trials in Africa show that a new malaria vaccine is effective at preventing both infection and the mosquito-borne disease itself in infants and children.
1. America has the best health care in the world.
Let's bury this one once and for all. The United States is No. 1 in only one sense: the amount we shell out for health care. We have the most expensive system in the world per capita, but we lag behind many developed countries on virtually every health statistic you can name.
Experts predict that as a result of the so-called JUPITER study, which seemed to show that the statin drug Crestor lowers the risk of heart attacks and strokes in those with high levels of inflammation, will lead to millions of people being put on statin drugs.
But the benefits were actually tiny -- about 0.72 percent of the statin takers in the trial had a heart attack or stroke, compared with 1.5 percent of those taking placebos.
The outgoing Bush administration is planning to announce a broad new "right of conscience" rule permitting medical facilities, doctors, nurses, pharmacists and other healthcare workers to refuse to participate in any procedure they find morally objectionable, including abortion and possibly even artificial insemination and birth control.
For more than 30 years, federal law has dictated that doctors and nurses may refuse to perform abortions. The new rule would go further by making clear that healthcare workers also may refuse to provide information or advice to patients who might want an abortion.
Brand-name drugs used to treat cardiovascular disease are no better than generics, a new review of available evidence shows.
Yet a number of editorials in medical journals, written by specialists, have urged against substituting the less expensive generics for their designer counterparts.
