July 24, 2012 - Doctors say a popular treatment for multiple sclerosis is not effective. A new study in the Journal of the American Medical Association finds the drugs called interferon beta, do not slow down the progression of the disease and they do not prevent or delay long term disability. Patients who used interferon beta drugs were as likely to experience long-term disability as patients who did not. Researchers say doctors should question regular use of the drugs.
Also, a British study finds a lack of physical activity causes 10 percent of deaths. Doctors say people who don't exercise regularly are at a higher risk of heart disease, diabetes and cancer. Researchers believe physical inactivity can shorten life expectancy similar to smoking and obesity. New research in The Lancet finds about one in 10 deaths worldwide are caused by people not getting up and engaging in physical activity such as walking 30 minutes a day for five days a week. The researchers concluded people's failure to spend a minimum of 150 minutes of moderate physical activity each week led to about 6 percent of cases of coronary heart disease, about 7 percent of Type 2 diabetes cases, and 10 percent of breast and colon cancers which adds up to 5.3 million deaths tied to physical inactivity. Smoking, meanwhile, is responsible for about 5 million deaths worldwide.
