Most US women face stroke risk

Regular doses of vitamin E may reduce the risk of life-threatening blood clots in women,researchers reported recently.But they cautioned that more research is needed to confirm the link in the prevention of the clots,known as venous thromboembolism,and said patients should not stop taking prescribed blood thinners."The data indicated that,in general,women taking vitamin E were 21% less likely to suffer a blood clot," the American Heart Association,which published the finding in its journal Circulation ,said in a statement.

Hepatitis is an inflammation of the liver.Inflammation causes soreness and swelling.Drinking too much alcohol,abusing drugs and taking some medicines can cause hepatitis.Many viruses can cause hepatitis,too.There are 2 main kinds of hepatitis,acute hepatitis and chronic hepatitis.When a person has hepatitis,the liver may become inflamed very suddenly.This is called acute hepatitis.If you have acute hepatitis,you might have nausea,vomiting,fever and body aches. How does Hepatitis affect the liver? The liver breaks down waste products in your blood.When the liver is inflamed,it doesn't do a good job of getting rid of waste products.One waste product called bilirubin,begins to build up in the blood and tissues when the liver isn't working right.The bilirubin makes the skin trun a yellow-orange colour(jaundice). What is Hepatitis C? Several viruses can infect the liver.There are 3 main types:hepatitis A,B and C. Hepatitis C is usually spread through contact with blood products,thr...

A new collaborative research has shown that the stem cells in the brain decrease ischemic injury and restore brain function.The research carried out by researchers at the Mario Negri Institute in Milan,Italy, the Istituto Neurologico Besta,and the University of Laussanne has been published online in PloS ONE .Ischemia is an absolute or relative shortage of the blood supply to an organ.Relative shortage means the mismatch of blood supply (oxygen delivery) and blood request for adequate oxygenation of tissue.Stroke is the first cause of permanent invalidity and the third cause of death in industrialised countries.

People who tend to be sedentary-as indicated by the amount of time they spend watching television-are likely to have high levels of glucose in their blood, even though they may not be diabetec.David W.Dunstan,of the International Diabetes Institute,Melbourne, Australia,and colleagues examined the association between television viewing and blood glucose levels,measured after fasting and after a glucose test-drink,in 3781 men and 4576 women in Australia. All of the subjects were free of diabetes at the time.

Women who use a contraceptive patch appear to be more than twice as likely to develop a dangerous blood clot in their veings as those who use an oral contraceptive, new research shows. Alexander M Walker and colleagues, form i3 Drug Safety in Auburndale, Massachusetts, note that it was not known if users of the patch system ran the same risk of stroke, heart attack and venous blood clots as users or oral contraceptives. They point out that the FDA changed the labelling for the patch contraceptive system in 2005 to warn of a possible increased risk of socalled "thrombotic events," because of a higher average circulating estrogen elvels with the product.

For people who suffer a stroke and are treated quickly with the clot-buster drug rtPA to open up the blocked brain artery, recovery of function is likely to be better for men than women, new research shows. However,more men than women die from the stroke. "Other studies have shown that women have worse functional outcomes after stroke;this shows that this is also true when women are treated with rtPA," said lead author Mitchell S V Elkind from Columbia University Medical Centre in New York, in a statement. The goal of stroke treatment is to administer a clot-busting drug within three hours after a stroke begins, so that blood flow to the brain can be restored before too much damage is done.
