young women increase stroke risk by smoking
Stroke is the third-leading cause of death, behind heart disease and cancer, in America. A new study reports that the more young women smoke, the higher their risk of suffering a stroke. Researchers found for that for every 1 to 10 cigarettes smoked a day, stroke risk increased 2.2 times; for every 21 to 39 cigarettes, risk increased 4.3 times. A study is planned on men.
Webcasts' topic: living with MS
Multiple sclerosis is a progressive disease of the nervous system affecting about 400,000 Americans. The National Multiple Sclerosis Society, together with MS LifeLines, will host two live Webcast programs to provide advice to young adults with the disease. The first program takes place at 8 p.m. Sept. 16, the second is at 8 p.m. Nov. 18. Both will include doctors and people living with MS in their 20s and 30s. The Webcasts can be viewed at www.realtalkrealanswers.com.
Anti-UV lenses cut risk of cataracts
The most common type of eye cataracts are related to aging, but other risk factors include family history, medical problems, injury to the eye and too much exposure to the sun's rays. This last can be reduced by using UV-protective sunglasses or contact lenses and by wearing hats when outdoors for longer than 15 minutes, even on cloudy days. The American Academy of Ophthalmology also reports cataract risk may be cut by eating dark green, leafy vegetables. For more information, go to www.geteyesmart.org.
More juices may cut drug efficiency
Scientists and consumers have known for years grapefruit juice can increase the absorption of certain drugs, with the potential for turning normal doses toxic. New evidence suggests grapefruit, orange and apple juices can have the opposite effect, by substantially decreasing the absorption of some drugs. Among drugs affected are some prescribed for fighting heart disease, cancer, organ-transplant rejection and infection, says study leader David G. Bailey. With colleagues, Bailey announced years ago that grapefruit juice can boost levels of the high-blood-pressure drug felodipine, causing dangerous effects from excessive drug concentrations.
