A life well spent: Consume now (in case you die early)

Posted: 10 Jun 2014 09:20 AM PDT

An early death constitutes a serious loss that should imply compensation to the deceased person. But how – when the person is dead? A team of economists argues that a 'life well spent' might entail consuming more and working less earlier in life. They construct a mathematical model to measure the economic losses associated with an early death.

In the last 30 years, since mammography was introduced, late-stage breast cancer incidence has decreased by 37 percent, a new study finds. The analysis takes into account an observed underlying trend of increased breast cancer incidence present since the 1940s, a sort of inflation rate for breast cancer.

About one percent of adults report they have experienced headaches associated with sexual activity, and that such headaches can be severe. But the actual incidence is almost certainly higher, according to a neurologist and headache specialist. "Many people who experience headaches during sexual activity are too embarrassed to tell their physicians, and doctors often don't ask," he said.

When women are choosing a contraceptive, health care providers should be aware that the things they want to discuss may differ from what women want to hear, according to a survey. Most of the information women receive about contraceptives focuses heavily on the effectiveness in preventing pregnancy, but this information was ranked fifth in importance by women, according to the study.

What's the best test for cervical cancer? Pap, HPV or both?

Should US women be screened for cervical cancer with Pap tests, HPV tests or both? According to researchers, while the merits of screening tests and screening intervals warrant further discussion, they firmly believe that increasing the number of women who participate in cancer screenings and ensuring that women are not lost to follow-up with lengthened screening intervals is more important than the choice of test to decrease rates of cervical cancer.

Posted: 09 Jun 2014 05:50 PM PDT

The mineral micronutrient content of four types of grain legumes has been examined in a new study. Grain legumes are often overlooked as valuable sources of micronutrients, such as zinc and potassium. Diets that do not provide adequate amounts of micronutrients lead to a variety of diseases that affect most parts of the human body. One researcher notes, "Iron deficiency is the most common, followed by zinc, carotenoids, and folate."

Parent and child must get enough sleep to protect against child obesity

Is sleep one of your most important family values? A new study suggests that it should be, reporting that more parental sleep is related to more child sleep, which is related to decreased child obesity. And the effects of sleeplessness go beyond just being tired the next day.

Confiding in friends, not relatives, shows health benefits in older adults, following loss of spouse

Posted: 09 Jun 2014 12:33 PM PDT

Older adults who lose their spouse tend to fare better health-wise if they have a friend -— someone who is not a family member -— in whom they can confide. Why not a family member? A researcher explains that the emotional complexities of family can add stress. "Friendships are discretionary while family relationships are obligatory," she says, "and past research shows that obligatory relationships can be less beneficial than discretionary relationships during times of stress."

Humanitarian liking on Facebook

'Liking' a page on the social networking site Facebook is a new form of civic engagement and humanitarian support, researchers conclude. According to the paper's authors, social motives and an emotional response underpinned users' inclination to like, or follow, a page, rather than their simply seeking information and news.
