show that reading, juggling or learning and practicing a musical instrument improves the organization and structure of the brain's white matter.Before the MRI, the children were given cognitive tests, while the parents filled out a new scoring system on screen time developed by the American Academy of Pediatrics.The test measures how much access a child has to a screen (allowed at meals, car, in line at store?), the frequency of exposure (age started, number of hours, at bedtime?), content (chooses own? watches fighting or songs or education?) and "dialogic" interaction (does the child watch alone or does a parent interact and discuss the content as well?).The results showed that children who used more than the AAP's recommended amount of screen time, of an hour a day without parental interaction, had more disorganized, underdeveloped white matter throughout the brain."The average screen time in these kids was a little over two hours a day," Hutton said. "The range was anywhere from about an hour to a little over five hours."In addition, the tracts of white matter responsible for executive functions were also disorganized and underdeveloped (the parts of the brain shown in blue in the image)."These are tracks that we know are involved with language and literacy," Hutton said, "And these were the ones relatively underdeveloped in these kids with more screen time. So the imaging findings lined up pretty perfectly with the behavioral cognitive testing finding."'Neurons that fire together wire together'"These findings are fascinating but very, very preliminary," pediatrician Dr. Jenny Radesky wrote in an email. Radesky, who was not involved in the study, is the lead author on the American Academy of Pediatrics 1736

Surveillance of legal abortions in the US helps "to guide and evaluate the success of programs aimed at preventing unintended pregnancies," the report says.According to the most recent study, unintended pregnancies in the United States have gone down from 51% in 2008 to 45% in 2011-2013.The rate of abortions can be influenced by a number of factors, the report shows, including availability of contraception, information and health care; access to abortion providers; changes in laws; and shifts in the economy and in attitudes about things like nonmarital childbearing.Lowering the number of both unintended pregnancies and abortions often go hand-in-hand, the study shows.And you can't talk about unintended pregnancies without talking about abortions, said Jones of the Guttmacher Institute."Affordable access to the full range of contraception and family planning options is critical for people deciding if and when they'd like to become parents, develop their careers, plan for their futures, and manage their health," she said. "For women who become but do not want to remain pregnant, access to safe, legal abortion services remains critical." 1152
