【正文】 the medicines into a single pill, taken just once a day. Now, two panies say they have done that for people just starting treatment for HIV, the virus that causes AIDS. The panies are BristolMyers Squibb and Gilead Sciences. They have developed a single pill that bines three drugs currently on the BristolMyers Squibb sells one of them under the name of Gilead bined the others, Emtriva and Viread, into a single pill in two thousand four. Combining drugs involves more than technical issues. It also involves issues of petition if the drugs are made by different panies. The new oncedaily pill is the result of what is described as the first joint venture agreement of its kind in the treatment of HIV In January the New England Journal of Medicine5 published a study of the new pill. Researchers pared its effectiveness to6 that of the widely used bination of Sustiva and Combivir. Combivir contains two drugs, AZT7 and The researchers say that after one year of treatment, the new pill suppressed HIV levels in more patients and with fewer side Gilead paid for the study. Professor Joel Gallant at the Johns Hopkins School of Medicine in Baltimore, Maryland, led the research. He is a paid adviser to Gilead and BristolMeyers Squibb as well as the maker of Combivir, GlaxoSmithKline. Glaxo Smith Kline reacted to the findings by saying that a single study is of limited value. It says the effectiveness of Combivir has been shown in each of more than fifty studies. The price of the new oncedaily pill has not been announced. But Gilead and BristolMyers Squibb say they will provide it at reduced cost to developing countries. They plan in the next few months to ask the United States Food and Drug Administration10 to approve the new pill. There are limits to who could take it because of the different drugs it contains. For example, pregnant women are told not to take Sustiva because of the risk of birth Experts say more than forty million people around the world are living with HIV *9 Many Women Who Beat Cancer Don39。t Change Habits Many women who battle breast cancer will tell you it39。s a lifechanging experience. However, a new study shows that for many women, the changes aren39。t always positive or permanent. Beth Snoke has watched her mother and both grandmothers battle and survive breast 2 cancer So when she was diagnosed, there was no doubt in her mind what she had to do. I do exactly what the doctors say as far as the medicine that I39。m on, as far as the vitamins, the diet, and the fitness. And I can39。t stress enough how important that is, says Beth Snoke. But a surprising new study shows that no every woman who beats breast cancer is getting that message. In fact, nearly 40% bf them say even after surviving breast cancer, they haven39。t made significant changes in the way they eat or how much they exercise. Not all survivors are taking advantage of this teachable moment and making positive health changes in their life, says Electra Paskett, PhD, at Ohio State University39。s Comprehensive Cancer Center. Paskett says diet and exercise have been proven to not only help women feel better during and after treatment, they may also play a role in preventing some cancers from ing back. Despite growing evidence, some women just aren39。t listening. Colon cancer survivors who exercise have actually been shown to have improved survival rates. So, yes, it is true that perhaps by making some of these health y choices we can actually increase their health, says Paskett. As a breast can
