HealthWise at 5 From 11.29

  • Elderly Exercise

A new study says senior citizens need to get moving. A report by the the Center for Disease Control and Prevention along with the Merck Institute of Health and aging says older Americans aren't doing enough to stay healthy. According to the study, one-third of people over 65 don't exercise and two-thirds of seniors don't eat enough fruits and vegetables. The report also says doctors and communities need to be more involved in senior health. Researchers say Hawaii has the healthiest senior population. The survey also shows that seniors are doing better than younger Americans: one-fifth of all seniors are obese, while the average in all adults is 30%. For more information ( click here ).

  • Back Brain

Who would have thought your aching back could shrink your brain? That's the latest theory after studying the brain images of several dozen people, some with chronic back pain, compared to others with a healthy back. Researchers at Northwestern University found that chronic back pain could shrink the brain by as much as 10% and that the longer the pain lasted, the more likely there was to be a loss of gray matter, which is the part of the brain that processes information and memory. Researchers are not exactly sure how chronic pain may be connected with brain shrinkage but they say chronic pain and the associated stress may be partially responsible. The good news is researchers believe that treatment could reverse this effect. 

  • Cell Based Flu Vaccine

A late-stage clinical trial is testing a flu vaccine made without eggs. Eggs are the traditional incubator for the flu vaccine, a process that takes at lease six months to complete. A new trial is checking the effectiveness of Flublok, a vaccine developed using an insect cell line and flu virus antigens. The use of an insect cell line could cut up to two months off the vaccine production process. Hundreds of volunteers will be injected with the experimental vaccine at a few research sites in the United States.
