Last week, Nintendo became the latest consumer electronics maker to warn that kids shouldn’t use their three-dimensional image-based gaming devices because they may have a negative impact on development of the human visual system.
The warning came just a month before the company’s much anticipated release of the 3DS, which is just such a device that features a 3.5-inch screen which can create 3-D images without the need for special glasses. The 3DS is Nintendo’s most anticipated new product since it released the iconic Wii gaming device in 2006.
Sony’s PlayStation3, a similar product that requires glasses to create the 3-D effect, already carries a similar warning, as do 3-D TV sets made by Sony, Samsung, and Panasonic.
Nintendo’s warning applies to kids that are six years old or younger. The Japanese company advised parents to block access to the game machine’s 3-D mode for these kids, while adding that it was okay for them to use the 3DS in 2-D mode. Read more »

Cancer of the ovary is a particularly nasty disease. It often remains asymptomatic until it has reached an advanced, incurable stage, and scientists have been unable to develop an effective screening test for the disease like the ones in widespread use for cancers of the breast and cervix.
The dismal status of ovarian cancer screening was underscored a year ago when an NIH-sponsored study showed that over 70 percent of cancers detected by transvaginal ultrasound and CA 125 biomarker testing — the two best ovarian screening tests we’ve got — had reached stage III or IV at the time the patients screened positive. That’s about what happens when women aren’t screened at all.
That wasn’t the worst of it, however. In just the first year of that screening program, positive test results obligated 566 surgical procedures which uncovered only 18 cancers. That’s an awful lot of unnecessary surgery and associated morbidity right there. Things were no better on the false-negative side of things. Overall, 89 cases of ovarian cancer were diagnosed during the NIH study, and a third of them had been missed by both screening modalities.
What’s new?
The NIH study didn’t evaluate the impact of screening on ovarian cancer mortality, but a recent study by Laura Havrilesky and colleagues at Duke did indeed address the point. Sadly, the results were abysmal. Read more »

Emerging economies must act immediately to halt rising obesity rates before the epidemic becomes as severe as it is in first-world countries, according to new report by the Organization for Economic Cooperation and Development (OECD).
The OECD report was published in the Lancet. It characterizes the prevalence of obesity in Brazil, China, India, Mexico, Russia and South Africa. Obesity rates were found to vary dramatically across these six countries. In Mexico, a stunning 70 percent of adults were reported to be overweight or obese. Nearly half of all Brazilians, Russians and South Africans fell into these categories. China and India had a lower prevalence of overweight and obesity, but were moving rapidly in the wrong direction, according to the OECD.
Developing nations don’t have enough resources to handle the health consequences of obesity, which include an increased risk of cardiac disease, stroke, cancer, diabetes, arthritis, and disability from all causes.

Just about everybody agrees that kids should eat breakfast every day. Breakfast improves their overall nutrition and their performance in school, among other things. But how helpful can breakfast really be if it consists of cereal deluged in sugar?
“Not very” is the answer.
Thankfully, a new study by Jennifer Harris and colleagues at Yale suggests that kids are perfectly willing to consume low-sugar cereals instead, particularly if they can add a pinch of table sugar or fresh fruit to the mix.
To evaluate kids’ willingness to eat low-sugar cereals, Harris’ team randomized 91 kids between the ages of five and 12 to two groups. Kids in the first group were offered low-sugar cereals like Cheerios, Corn Flakes, and Rice Krispies, which contain one to four grams of sugar per serving. Kids in the other group chose between Cocoa Pebbles, Frosted Flakes and Fruit Loops, which contain about 12 grams of sugar per serving.
Kids in both groups were also offered orange juice, 1 percent milk, pre-cut sections of bananas and strawberries, and sugar packets. The kids served themselves and then completed a questionnaire about their breakfast. Read more »

The FDA has been tough on diet drugs of late. Three years ago it scuttled an attempt to get the European diet drug rimonabant approved for use in the U.S. More recently it rejected, at least temporarily, applications for Qnexa and Lorcaserin.
But that trend may have been reversed last week, when an advisory committee set the stage for possible FDA approval of Orexigen’s investigational diet drug, Contrave. By a 13-7 vote, the committee said in essence that the somewhat modest beneficial effects of the drug outweighed its tendency to increase blood pressure.
The FDA will make final decision on the matter by the end of January. It is not required to follow the advice of its advisory committees, but as was the case for the three diet drugs mentioned above, it usually does. Read more »
