A research by Rudolph Tanzi of Massachusetts General Hospital and his team have found four more genes that affect the risk of Alzheimer’s disease.

Tanzi's team analyzed samples from more than 1,300 families to come to a conclusion. They also feel that the latest study would help in finding better treatment for the disease.  "We are on the cusp of a rare 'science moment' that could alter the way we diagnose, treat and prevent Alzheimer's disease," said Rudolph Tanzi.

Hot flushes, night sweats and painful joints are good signs for women who are on hormone – based drugs for breast cancer. The symptoms mean that the tumors are less likely to recur in these women.

According to a new study led by Jack Cuzick of Cancer Research UK, women who were taking anastrozole or tamoxifen for breast cancer and experienced menopausal like symptoms had less likelihood of recurrent tumors.

The researchers used data from 4,000 women with early-stage breast cancer. It was found that for women who developed joint symptoms after the treatment, the recurrence rate was reduced by about 41 percent. But those who developed more vasomotor symptoms, the recurrence rate decreased by 47 percent.

The FDA did not pay heed to evidence while declaring BPA safe for plastics in baby bottles.

An expert panel reviewed  the FDA’s handling of the controversial subject. According to the report of the panelists, the FDA failed to consider studies calling into question the safety of bisphenol A while declaring it safe.

In response to the attack on the claim of the FDA, it quickly issued a statement saying that its view was "based on all available evidence" which indicated that current levels of exposure to BPA through food packaging do not pose an immediate health risk to the public, including infants and babies.

A new study has disclosed that vigorous exercise lowers the chances of developing breast cancer by almost a third.

The defensive effect of strenuous exercise such as scrubbing floors, cleaning windows and dancing was only obvious in women with normal weight, the researchers said.

The other vigorous activities include running, fast jogging, competitive tennis, aerobics, hill cycling, digging, and chopping wood.

The research made by doctors followed the lifestyles and health of 32,269 postmenopausal women for 11 years.

Advocacy group Public Citizen said GlaxoSmithKline PLC's diabetes drug Avandia should be banned in the United States as it can cause death from liver failure and has other life threatening risks which are more than the benefits itoffers.

The American Diabetes Association and the European Association for the Study of Diabetes issued guidelines which said that members of a joint medical panel "unanimously advised against using" Avandia.

The drug already carries a “black box” warning of its increasing the risk of heart attacks and now the Public Citizen group asked the U.S. Food and Drug Administration to ban the drug citing the drug induced liver failure in 14 cases. 12 of these have resulted in liver related death.

U.S. researchers said a combination of talk therapy and antidepressant medication was the best treatment for children and adolescents suffering from disabling anxiety disorders.
