Banana Boat UltraMist Sunscreen Recalled After Users Catch Fire

Nearly two dozen types of Banana Boat UltraMist spray-on sunscreen are being recalled after reports of people catching on fire after applying the lotion, says product maker Energizer Holdings.

In the last year, there have been four reports of in the United States and one report in Canada of people catching on fire after applying the sunscreen and getting close to open flame, CBS News/Associated Press reported.

More than 20 million units of the 23 UltraMist products have been sold since being introduced in 2010.

"Energizer believes that this issue is associated with the product delivery system, specifically the size of the spray valve opening on the affected products," the company said in a statement, CBS/AP reported.

"The spray valve opening on the affected products dispenses more than is typical in the industry for continuous sun care sprays. As a result, the product is taking longer to dry on the skin than is typical with other continuous sprays. If a consumer comes into contact with a flame or spark prior to complete drying of the product on the skin, there is a potential for the product to ignite," Energizer explained.

For more information, consumers can phone the company at 1-800-723-3786.

Diet, Exercise Fail to Reduce Cardiovascular Risk in Diabetes Patients: Study

A U.S. study examining whether diet and weight loss can prevent heart attacks and strokes in overweight and obese people with type 2 diabetes was halted two years earlier than scheduled because it found no benefits.

The study of more than 5,100 patients compared outcomes among those in a control group who received general health information and those in an intervention group who did at least 175 minutes a week of moderate exercise and consumed either 1,200 to 1,500 calories per day (those weighing less than 250 pounds) or 1,500 to 1,800 per day (those weighing more), The New York Times reported.

After 11 years, the control group and intervention group had nearly identical rates of heart attacks, strokes and cardiovascular deaths. The data is currently being analyzed and will be published in research papers.

"I was surprised," said Rena Wing, the study's chairwoman and a professor of psychiatry and human behavior at Brown University's medical school, The Times reported.

Like many, Wing believed that diet and exercise would help these patients, partly because short-term studies showed that those approaches lowered blood sugar levels, blood pressure and cholesterol levels.

Despite the study results, experts say there are many benefits to diet and exercise even if they did not lower cardiovascular disease risk in people with diabetes, The Times reported.

Bone Marrow Transplant Pioneer Dies

An American researcher who received the 1990 Nobel Prize in medicine for his work to perfect the bone marrow transplant died Saturday at the Fred Hutchinson Cancer Research Center in Seattle.

E. Donnall Thomas, 92, had heart and lung problems, according to his wife and longtime research collaborator Dottie Thomas, the Wall Street Journal reported.

Bone marrow transplants have saved tens of thousands of patients with leukemia, lymphoma, multiple myeloma, aplastic anemia, myelofibrosis and a number of autoimmune diseases.

Thomas also helped found the Fred Hutchinson Cancer Research Center nearly four decades ago, WSJ reported.
