NEW YORK (Reuters) - A Manhattan federal judge refused to block a New York City regulation requiring people who perform circumcisions and use their mouths to draw away blood from the wound on a baby's penis to first obtain written consent from the parents.

Screen time not linked to kids' physical activity

NEW YORK (Reuters Health) - Cutting back kids' time watching TV and playing video games may not encourage them to spend more of the day running around outside, a new study suggests. Just four in 10 U.S. kids met dual national guidelines for getting enough physical activity and for limiting "screen time," researchers found - but the likelihood of kids exercising regularly didn't depend on whether they kept away from screens.

Study finds increase in unused transplant livers

NEW YORK (Reuters Health) - The number of donor livers thrown away in the U.S. has increased since 2004 due - in part - to a population growing older and heavier, according to a new study that also points to changes in medical practice that may make some donor livers less viable. "The rationale for looking at this question in the first place is that the number of liver transplants done in the U.S. has gone down," said the study's lead author Dr. Eric Orman, a fellow at the University of North Carolina at Chapel Hill.
