HealthDay (2/21, Preidt) reported that a study published in the February issue of the journal Pain suggests that “high doses of” opioids may be associated with an increased risk for depression. The study, which “involved 355 patients in Texas who reported low back pain at an initial medical visit and still had the pain one and two years later,” revealed that patients “who used higher doses of narcotic painkillers to manage their pain were more likely to have an increase in depression.”

MedPage Today (2/21, Firth) reported that a report on children published in the January/February issue of the journal American Pediatrics reveals that “inpatient visits for suicide, suicidal ideation, and self-injury rose by 104% from 29,000 in 2006 to just below 59,000 in 2011, while ‘all-cause’ children’s hospitalizations have not increased.” The report was “based on the 2006 and 2011 AHRQ’s Healthcare Cost and Utilization Project (HCUP) which sources data from two national databases that estimate hospital visits and analyzes patterns of emergency department use.”

NPR (2/19, Hamilton) reports in its “Shots” blog and on its “All Things Considered” program reports that a study in the current issue of the Journal of Neuroscience suggests that “positive emotions — like feeling calm and safe and connected to others — can minimize pain,” whereas “negative emotions tend to have the opposite effect.” Researchers arrived at these conclusions after monitoring “the brain waves of a dozen people” who were asked to take part in a series of experiments.

The NBC News (2/19, Fox) website reports that a study published in the Proceedings of the Royal Society B suggests that “teenage fathers pass along six times as many genetic mutations to their kids as do teenage mothers.” After examining “the DNA of more than 24,000 parents and their children,” investigators “found that when the father was 20 or younger, the children had many more mutations than did children of older dads, as well as many more mutations than the offspring of teen mothers and adult dads.”

The Telegraph (UK) (2/18, Donnelly) reported that the study authors “said the findings could explain why the children of younger fathers have been found to have a higher risk of disorders such as autism, schizophrenia and spina bifida, which have some genetic links.”

TIME (2/19, Sifferlin) reports that a study published in the February issue of the journal Medicine & Science in Sports & Exercise suggests that “women who keep exercising into midlife can prevent depression.” After examining “10 years’ worth of data from 2,891 women between ages 42 and 52, who filled out questionnaires about their depressive symptoms and levels of physical activity,” researchers discovered that “women who were meeting public health recommendations for physical activity – 150 minutes a week of moderate intensity exercise – reported fewer depressive symptoms.” What’s more, greater amounts of physical activity were tied to a decreased likelihood of depression.
