There’s not enough evidence to say whether testing and treating children for high blood pressure is a good idea, a panel of experts says. The new report comes from the U.S. Preventive Services Task Force. This is a government-appointed panel that provides advice on preventive care. The task force looked at research on kids and blood pressure published in the last 10 years. The group said it’s hard to predict which children will have high blood pressure as adults. There’s also not enough research on whether treating kids with high blood pressure will improve their heart health as adults. And there’s been little research on whether blood pressure medicines are safe and effective for long-term use by children. The task force said more research is needed. Meanwhile, we do know some things that kids can do to stay healthy, the task force said.

For several years, doctors have been curing dangerous colon infections by transplanting feces containing normal, healthy bacteria into the diseased colon. Now there’s an easier way to deliver the dose: poop pills. Actually, feces from a donor are processed so there’s nothing left but the bacteria. Placed in pills and then swallowed, the healthy bacteria replace the cause of infection: Clostridium difficile (C. diff). These infections often occur in people who take antibiotics for another reason. The drugs also kill healthy bacteria in the gut. But C. diff lives in hardy spores that can become active when other bacteria disappear. C. diff causes dangerous inflammation and diarrhea. Doctors have used transplants of feces to cure C. diff infections that keep coming back. The transplants were put into the colon through the nose or rectum.

Women pregnant with twins may not need to have a cesarean section, a new study suggests. Many can have a safe vaginal delivery, the study found. The study included nearly 2,800 women who were scheduled to deliver full-term twins. The babies were at a healthy weight, and the first twin was in the usual head-down position. Women were randomly assigned to have either a planned C-section or a planned vaginal delivery. But doctors could make a different decision based on their judgment at the time of delivery. About 91% of women in the planned-cesarean group had C-sections. About 56% of those in the other group did have vaginal deliveries. The others had C-sections or a combination delivery. Researchers kept track of mothers and babies for a month after the births. Problem rates were similar for both groups.
