Avoiding certain health problems in middle age dramatically improves your lifetime chances of preventing a heart attack or stroke, a new study finds. The study included about 250,000 people. It looked at a person’s lifetime risk based on their health at certain ages. Researchers put together the numbers from 18 prior studies. To gauge health, they focused on the standard factors that most strongly increase the risk of heart attack or stroke. They are smoking, high cholesterol, high blood pressure and diabetes. The study found that people with none of these risk factors at mid-life had very little chance of a heart attack or stroke in the rest of their lives. An example would be a 45-year-old male nonsmoker with ideal cholesterol and blood pressure, and no diabetes. His chance of ever having a heart attack or stroke would be 1.4%, researchers said.

Two women with very limited vision appeared to improve after treatment with embryonic stem cells, researchers report. These cells are removed from human embryos. They can grow into many types of cells. Both women had some vision but were legally blind. Both had macular degeneration. This disease causes loss of central vision. One woman had the common “dry” form. The other woman had a rarer type. Each woman was injected in one eye with embryonic stem cells. Four months later, they showed some improvement in eye tests. For example, both could read more letters on vision charts. Doctors said the treatment appeared to be safe. The women had no signs of rejection or abnormal growths. The journal Lancet published the study online January 23. The Associated Press wrote about it.

A new report calls for more research to find the best ways for parents and other caregivers to fight obesity in children. The American Heart Association issued the statement. It reviewed studies that took different approaches. Some of these have been linked to better results. They include changing behaviors as a family, setting clear goals, keeping track of progress and keeping healthy foods in the home. About 17% of the studies found that kids lost more weight when parents were involved in treatment. Some studies also found that a role for parents also helped kids to keep weight off longer. But in other studies family involvement did not make a difference. The study authors said research has not focused enough on the roles of culture, family relationships and parenting styles, among other things. The journal Circulation published the study.
