Researchers have discovered a biomarker that may help prevent a devastating intestinal disease that occurs in one of every 10 early preterm infants. The Cincinnati Children’s Hospital Medical Center study may help prevent necrotizing enterocolitis (NEC), a condition primarily seen in preemies in which bowel tissue dies. The death rate approaches 30 percent. Survivors are at risk for short-bowel syndrome (caused by surgical removal of the small intestine) and neurodevelopmental disability.
