Got a minute? You could save livesThink fast. If you were in a public place, and someone suddenly collapsed, would you know what to do? According to research presented at the American Heart Association's Scientific Sessions 2013 conference, this one-minute video could teach bystanders cardiopulmonary resuscitation, or CPR, even if they've had no previous instruction.

Study: Heavy coffee drinking in people under 55 linked to early deathWhen you make coffee with breakfast, or grab a to-go cup at a cafe before work, or raid your office's break room for a cup in the afternoon, you're probably not thinking about how scientists are studying it. So we'll just tell you: Many studies have looked at the health effects of coffee, even though measuring the potential harms and benefits is not as easy as chugging a shot of espresso. Since a whole range of lifestyle and genetic factors influence a person's physical well-being, it's hard to know exactly if, or how, or to what extent, coffee would be good or bad for anyone's longterm health. The latest study [PDF], published in the journal Mayo Clinic Proceedings, found an association between drinking more than 28 cups of coffee a week and an increased risk of death from all causes, in people 55 years old and younger. One cup of coffee is 8 ounces. That doesn't prove that coffee causes death. It also seems to contradict a study in the New England Journal of Medicine last year, which found that people who drink two or more cups of coffee a day have a reduced risk of dying from particular diseases than those who consume little or no coffee.

Docs urged to address military kids' mental healthMore than 2 million children have been affected by the military deployment of at least one parent within the past decade, and thousands have had to cope with a parent's death or traumatic injury, experts say. Therefore, it's imperative that pediatricians and other health care providers address the mental health and well-being of children from U.S. military families, according to the American Academy of Pediatrics. "This is guidance (for the providers), but it is the first of its kind," said co-author Dr. Beth Ellen Davis, a pediatrician and retired U.S. Army colonel. "I could think of no better way to honor our service members than to help providers take care of their children."

Does it 'get better' for bullied gay or bisexual youth?The answer to that question depends on how you look at it, according to a study published in the journal Pediatrics. Lesbian, gay and bisexual (LGB) adolescents are victims of bullying twice as often as their heterosexual peers. But research finds that the overall incidence decreases after high school, particularly among girls. However, the scars of emotional distress remain significantly higher in LGB youth. "What we see is, slightly over half of LGB teens are bullied when they're ages 13 to 14, and then when they're ages 19 to 20, the rates of bullying are fewer than 10 percent," said study author Joseph Robinson from the Department of Educational Psychology at University of Illinois at Urbana-Champaign.

Young patients, docs can miss signs of heart disease, attackWhen some people think about heart disease, they think primarily of older adults. However, both doctors and young patients miss opportunities to recognize symptoms of heart problems and treat them proactively, according to research presented at the American Heart Association conference. A study discussed Tuesday found a common risk factor for heart disease - high blood pressure, or hypertension - often goes undiagnosed in younger patients. "This research directly addresses the public health burden in the U.S. as far as rising rates of hypertension among young adults, especially with the growing rate of obesity," said Dr. Heather Johnson, lead study author from the University of Wisconsin School of Medicine and Public Health.

Poor sleep and sleep habits in adolescence may raise health risksLack of quality sleep for adults may negatively impact heart health. Evidence now suggests that sleep problems during adolescence may increase health risks as well. The research appeared Monday in the Canadian Medical Association Journal. "When most people think about cardiovascular risk factors and risk behaviors, they don't necessarily think of sleep," said Dr. Brian McCrindle, senior author and cardiologist at SickKids in Toronto, Ontario. "This study ... shows a clear association between sleep disturbance (in adolescents) and a greater likelihood of having high cholesterol, high blood pressure and being overweight or obese."

Teens who 'sext' more likely to be sexually activeIf your adolescent is sexting, they may be already sexually active and engaging in risky behavior, a new study suggests. Researchers are trying to better understand if young people are at greater risk for HIV or other sexually transmitted diseases because they are sending sexually explicit photos or text messages via cell phones. "Sexting" is not an alternative to "real world" sexual behavior among adolescents, according to a new study published Monday in the journal Pediatrics. "The same teens who are engaging in digital sex risk taking through sexting are also the same teens that are engaging in sex risk with their bodies in terms of being sexually active and not using condoms," said lead study author Eric Rice, an assistant professor at the University of Southern California's School of Social Work in Los Angeles.  Marijuana use may be associated with testicular cancer in young men, a new study finds.

Marijuana use may raise risk of testicular cancerMarijuana may double the risk of testicular cancer among young men, particularly tumors that are more severe, according to a new study published in the American Cancer Society's journal, Cancer. "This is a very consistent finding now that marijuana seems to be associated with the worst kind of testis cancer that occurs in young men ... (it) may well be causal," said study author Victoria Cortessis, an assistant professor of preventive medicine at the University of Southern California's Keck School of Medicine in Los Angeles. Two previous studies in 2009 and 2010 found similar associations.

Less sitting may lead to longer lifeWhat would happen if the entire population of adults in the U.S. reduced the amount of time they spent sitting or watching television? Researchers, whose work is published in the British Medical Journal Open, say Americans may live longer. They estimate a gain of two years to life expectancy for reducing sitting to less than three hours a day, or an additional 1.38 years if everybody limited the time they spent plopped in front of the television to two hours. "Right now, if you're born in the U.S. this year, your life expectancy is 78.5 years," said Peter Katzmarzyk, Professor of Epidemiology at Pennington Biomedical Research Center in Baton Rouge, Louisiana. "What we're saying is, if you got everyone in the U.S. to sit less, that population-level life expectancy would be two years higher. Our life expectancy as a country would be 80 years."

FDA approves drug to treat some obese, overweight adultsSome people who suffer from chronic weight issues may soon get some help from a pill. The U.S. Food and Drug Administration Wednesday approved Belviq, or lorcaserin hydrochloride, to be combined with a reduced-calorie diet and exercise, for treatment of chronic weight problems. Specifically, the FDA says, it is approved for overweight or obese adults who have one or more medical conditions due to their weight, such as high blood pressure, type 2 diabetes or high cholesterol. |
