The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) performed a workforce survey to determine the number, distribution, and work-related activities of pediatric gastroenterologists in the United States of America (USA) and Canada, and compared these findings with the first workforce survey completed in 1996. ⋯ There is currently a self-perceived shortage of pediatric gastroenterologists as compared with 7 years ago, despite a constant proportion of pediatric gastroenterologists per million children. In the USA, nurse practitioners and physician assistants are being increasingly used to fill this need, and physicians in both Canada and the USA have increased the time they spend in clinical care.

Clinical TrialGut hormone profiles in critically ill neonates on extracorporeal membrane oxygenation.
The objective of this study was to gain insight into the hormonal responses to enteral nutrition in critically ill newborns requiring venoarterial extracorporeal membrane oxygenation (ECMO) by analyzing plasma gut hormone levels of gastrin, cholecystokinin and peptide-YY in relation to enteral nutrition. ⋯ Intestinal hormone levels showed normal responses after introduction of enteral feeding, comparable with those in age-matched controls without ECMO. These results do not provide an argument for withholding enteral nutrition even in the most severely ill neonates on venoarterial ECMO.

Patent ductus arteriosus, indomethacin and necrotizing enterocolitis in very low birth weight infants: a population-based study.
Patent ductus arteriosus is a risk factor for the development of necrotizing enterocolitis. The use of indomethacin to treat patent ductus arteriosus in preterm infants may either decrease the incidence of necrotizing enterocolitis by stabilizing or closing the ductus arteriosus or increase its incidence by a direct constricting effect on mesenteric blood vessels. The authors sought to evaluate the interrelationship between patent ductus arteriosus, treatment with indomethacin and the risk of necrotizing enterocolitis in very low birth weight infants. ⋯ Patent ductus arteriosus is an independent risk factor for the development of necrotizing enterocolitis in very low birth weight infants. Therapy with indomethacin did not have a significant effect on the risk for necrotizing enterocolitis.
