OBJECTIVE To reduce the incidence of necrotizing enterocolitis (NEC) among very low birth weight (VLBW) infants admitted to 8 intensive care nurseries from a 2010 baseline of 8.0% to <4.0% by 2012 and sustain for 6 months using quality improvement (QI) methodology. METHODS A multidisciplinary NEC QI team used the Vermont Oxford Network definition of NEC(More)
Increased production of nitric oxide (NO) and subsequent local cytotoxicity to mucosal epithelial cells has been proposed as a putative mechanism involved in the development of necrotizing enterocolitis (NEC). Intestinal epithelial cells (IECs) metabolize L-arginine to either nitric oxide (NO) by NO synthase (NOS) or to L-ornithine and urea by arginase.(More)
Background:Necrotizing enterocolitis is characterized by intestinal inflammation and epithelial barrier dysfunction. Mitogen-activated protein kinase (MAPK) phosphatase (MKP)-1 plays a pivotal role in the feedback control of MAPK signaling, which regulates inflammation and apoptosis. We hypothesized that MKP-1 prevents lipopolysaccharide (LPS)-induced(More)
OBJECTIVE To evaluate the short-term effects of feed fortification, feed volume increase, and PRBC transfusion on the odds of developing NEC. STUDY DESIGN Case-crossover study of neonatal intensive care infants born at ≤ 32 weeks' gestation who were admitted to 5 central Ohio intensive care units from January 2012-July 2016 and developed NEC Bell Stage(More)
