some sleep drugs do more than make you sleep

the united states food and drug administration1 has ordered companies to place strong new warnings on thirteen drugs that treat sleep disorders. it also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs.

last wednesday, the fda announced that some of these drugs can have unexpected and dangerous effects. these include the risk of life-threatening allergic reactions. they also include rare incidents of strange behavior. these include people cooking food, eating and even driving while asleep. the patients later had no memory of doing these activities while asleep.

last year, a member of the united states conGREss2 said he had a sleep-driving incident. patrick kennedy, a representative from rhode island,3 crashed his car into a security barrier near the building where lawmakers meet. the accident happened in the middle of the night and no one was hurt. mr. kennedy said he had earlier taken a sleep medicine. he said he was also being treated with a stomach sickness drug that can cause sleepiness.

the food and drug administration did not say in its announcement how many cases of sleep-driving it has documented. however, the new york times4 reported last year about people who said they had strange sleep events after taking the drug ambien. some reported sleep-driving and sleep-walking. others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep. but they had no memory of carrying out the activities.

a food and drug administration official says that these serious side effects of sleep disorder drugs appear to be rare. but, he also said there are probably more cases than are reported.5 he said the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs. the food and drug administration has advised drug companies to carry out studies to investigate the problem.

red meat links to higher risk of breast cancer1

exercise and keeping a healthy weight are two things that doctors say might help women lower their risk of breast cancer.

mothers may reduce their risk if they breastfeed for at least four months. for older women, hormone replacement therapy2 can lower the risk of some other diseases. but it has been found to increase the risk of breast cancer. so women should consider their choices carefully. the same may be said for diet.
    new findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone-receptor positive.3 the growth is fed by the levels of estrogen or another hormone, progesterone, in the body.

researchers at brigham women¡¯s hospital in boston, massachusetts, reported the findings as part of a health study of nurses. the researchers followed the health of more than 90,000 women from 1991 to 2003. those who ate the most red meat ate more than one and one-half servings a day. a serving was defined as roughly 84 grams. those who ate the least red meat ate less than three servings a week. this is what the study found about breast cancers that were hormone receptor-positive: the women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it.

eunyoung cho, the lead author of the report, says more research is needed to know the reason for the link. but in the past, researchers have suggested that three things may play a part. one is the way meat is cooked or processed. another is the use of growth hormones in cows. and the third is the kind of iron in red meat. the study appears in the archives of internal medicine.

and now we have more to tell you about our subject -- resveratrol. we discussed a study in the united states that found that large amounts of this plant compound helped fat mice live longer. the mice were fed much more resveratrol than people could get from red wine, one of the foods that contains it.

now, scientists in france say resveratrol also improves muscle performance -- again, at least in mice. they were able to run two times as far in laboratory treadmill tests4 as mice normally could. the study at the institute of genetics and molecular and cellular biology5 appeared in the journal cell.
