There is an associated 24% increase in pancreatic cancer risk for every 100 milligram decrease in magnesium intake per day, according to a study in the British Journal of Cancer. Researchers at Indiana University at Bloomington used a cohort of more than 66,000 adults, ages between 50 and 76, and found that age, body mass index and anti-inflammatory drug use didn't change the effect of magnesium intake on an individual's risk of developing pancreatic cancer.
Sugar-water injections, or dextrose prolotherapy, relieves osteoarthritis knee pain, according to a study in the Annals of Family Medicine from researchers at the University of Wisconsin and the University of Iowa. The study assigned participants to either sugar water or placebo injections or a home regimen of exercise.
A new study casts doubt on revised Institute of Medicine guidelines for women's weight gain during pregnancy for preventing large-for-gestational-age babies. This large, prospective study published online in Obstetrics & Gynecology found a positive association between a mother’s fat-free mass -- or, her total body mass minus the fat -- with increased birth weight, while no link was found between maternal fat mass and birth weight. The researchers evaluated birth outcomes for 2,618 pregnant women whose body composition was measured in the first trimester using multifrequency segmental bioelectric impedance analysis. Previous evidence linking maternal obesity -- which is usually determined by body mass index (BMI) -- with increased birth weight is problematic, say the authors, because BMI does not measure distribution of fat or fat-free mass. The findings are important, conclude the authors, because in 2009, the IOM lowered its recommended gestational weight gain for obese women to 5-9 kilograms due to concerns that increasing maternal obesity rates would result in more high birth-weight babies. The authors note that previously shown links between maternal obesity and large-for-gestational-age babies may be the result of gestational diabetes, rather than maternal obesity itself.

Children whose parents were exposed to diesel fumes at work before conception or during pregnancy had a greater risk of developing a brain tumor, Australian researchers wrote in the International Journal of Cancer. Diesel fumes recently have been classified as Group 1 carcinogenics by the International Agency for Research on Cancer.
Researchers at Florida International University found that, in limited cases, playing music during tasks was nearly as effective as medication in helping some boys with attention-deficit/hyperactivity disorder concentrate on schoolwork. The study examined boys who were on medication for ADHD and those who were not, as well as a control group of male students.
