CNN's Gupta Won't Be U.S. Surgeon General
Citing family and work considerations, CNN medical correspondent Dr. Sanjay Gupta has withdrawn his name as a candidate for U.S. Surgeon General, White House officials said Thursday.
Gupta had been under "serious consideration" for the post but decided he wants to focus on his medical career and spend more time with his family, an administration official told the Associated Press.
There were no problems that would have disqualified Gupta from becoming surgeon general, the official added.
In an interview with CNN's Larry King, Gupta noted he had two young daughters and a third child on the way.
"My wife is imminent with our third child. You know, this job ... takes us away from our children for so many years at once, and I sort of came to grips with the fact that I'd probably be away at least the first several years. ... And I just didn't feel like I should do that now," Gupta said in the interview.
Optimism Boosts Health, Life Span: Study
Optimists live longer and healthier lives than pessimists, according to a U.S. study of 100,000 women who were surveyed about their personality traits and then followed for eight years.
Those who said they were optimists were less likely to die from any cause and 30 percent less likely to die from heart disease. Women who were more pessimistic had a higher overall death rate and were 23 percent more likely to die from a cancer-related condition, ABC News reported.
The findings were presented Thursday in Chicago at the annual meeting of the American Psychosomatic Society.
Optimistic people may have less physical reaction to stress, or may be more likely to follow a doctor's advice and, therefore, maintain their health, suggested lead author Hilary Tindle, an assistant professor of medicine at the University of Pittsburgh, the AP reported.
Companies Halt U.S. Sales of Baby Bottles With BPA
Baby bottles made with the controversial chemical bisphenol A (BPA) will no longer be sold in the United States by the six largest manufacturers of the products.
The companies made the announcement after Connecticut Attorney General Richard Blumenthal and other colleagues asked them to voluntarily halt their use of the chemical, which has been linked to numerous health effects, the Washington Post reported.
"The evidence seems too clear and emphatic and unequivocal to say we should simply permit this stuff to go into children on a massive scale," Blumenthal said Thursday. "And there's no reason for it, because there are substitutes available."
BPA, which is found in a wide range of products, mimics the hormone estrogen and may disrupt the body's endocrine system. The chemical poses a particular threat to fetuses, infants and children because it can interfere with cell function when their bodies are still developing, public health experts say.
Last year, the National Toxicology Program, part of the U.S. National Institutes of Health, warned there was "some concern" BPA may affect the brain and behavioral development of fetuses, infants and young children, the Post reported.
Blumenthal is working to gain support from other attorneys general to demand that manufacturers stop using BPA to make infant formula cans and all other food and beverage containers.
Viruses May Cause Diabetes: Study
Common viruses that cause vomiting and diarrhea may trigger many cases of diabetes, according to British researchers, who said their findings raise the possibility of a vaccine.
They found evidence of enteroviruses in the insulin-producing pancreatic cells of 60 percent of children with type 1 diabetes and of 40 percent of adults with type 2 diabetes, BBC News reported.
The study was published in the journal Diabetologia.
It's known that genetics play a major role in diabetes risk, but the idea of a viral cause of diabetes has been considered for decades, BBC News reported.
Type 1 diabetes is an autoimmune disease. In children with a genetic predisposition to this form of diabetes, enterovirus infection may trigger the immune reaction that results in the disease, the researchers suggested.
Type 2 diabetes is often linked to obesity in adults. Enterovirus infection may harm the ability of beta cells in the pancreas to produce insulin. The researchers said this, in combination with the greater demand for insulin in obese people, may trigger diabetes, BBC News reported.
Religion May Ease Anxiety, Research Finds
Religious belief may help control stress-related anxiety, a University of Toronto study suggests.
Volunteers did a stressful task while researchers monitored activity in an area of the brain called the anterior cingulate cortex (ACC), which is involved in emotion, CTV.ca reported. Participants with strong religious belief had less ACC activity than non-believers, suggesting they experienced less anxiety while doing the task and when they made mistakes.
The study was published in the journal Psychological Science.
Religious belief may offer peace of mind that helps people control their anxiety, suggested study leader Michael Inzlicht, an assistant professor of psychology, CTV.ca reported.
"Religion provides meaning to many people. It helps people to understand what to do, where to go next, what decision to make. It may be that having this sense of meaning reduces their anxiety," he said.
