Background: Necrotizing enterocolitis (NEC) presents high mortality and postoperative, gastrointestinal and neurodevelopmental morbidity. There is limited information about NEC in Chile.
Aim: To describe the clinical/epidemiological behavior of newborns who underwent NEC.
Methods: Multicenter descriptive study of patients with NEC from seven hospitals of Santiago, Chile, during 2016. Descriptive statistics and univariate/multivariate analysis were performed (SPSS v22 software).
Results: 75 cases were collected. Median days of life at diagnosis was 11, gestational age was 29 weeks, birth weight 1,114 g. The incidence was 2.6 per 1,000 live newborns and mortality was 18.6%, higher in ≤ 750 g, ≤ 25 weeks and surgical NEC. There was 45.3% microbiological isolation and 19 different empirical antibiotic schemes were used for the treatment of NEC. The multivariate analysis showed a higher risk of surgery in umbilical arterial catheter users, CRP > 10 mg/L and positive microbiological isolation. The highest risk of death was in umbilical arterial catheter users.
Discussion: This ie the first multicenter study that collects local data information. The incidence was similar to that found in medical reports but with a lower mortality. There is no consensus of antibiotic treatment to use. With these results we hope to advance in improving the diagnosis and unify antimicrobial treatments, to reduce morbidity and mortality figures.

Breast milk is an essential source of infant nutrition. It is also a vital determinant of the structure and function of the infant intestinal microbial community, and it connects the mother and infant intestinal microbiota. Human milk oligosaccharides (HMOs) are a critical component in breast milk.

Purpose: To investigate the clinical features of necrotizing enterocolitis-associated intestinal perforation (NEC-IP) in neonates with different gestational ages (GAs). Furthermore, we also want to identify the risk factors of poor prognosis for these patients.
Methods: The retrospective study of patients with NEC-IP was conducted with basic information, comorbidity, intraoperative findings, related treatment, and prognosis.
WNT2B is Wnt ligand which is able to support intestinal stem cells (ISC) in culture and support the intestinal epithelium in vivo. We have previously shown that WNT2B is critical for resistance to colitis, but not small intestinal injury, in the adult mouse. WNT2B is thought to coordinate with WNT3 in supporting ISC, and we have also shown that WNT3 expression is low in the early postnatal ileum in mice.

Purpose: Necrotizing enterocolitis (NEC) majorly affects premature infants, causing not only necrosis and inflammation but also feeding intolerance and gastrointestinal dysmotility, hinting at gut hormone secretion impairment. Particularly critical is the gestation period before 26 weeks where intestinal hormonal activity is partially developed, rendering preterm neonates highly susceptible to NEC. Emerging evidence suggests a role of gut hormones, especially glucagon-like peptides (GLP) in ileum development.

Background: Preterm infants are at risk for necrotizing enterocolitis (NEC) and sepsis. Optimal strategies of preterm feeding to achieve full enteral feeding early with minimal duration of central lines without increasing the risk of NEC remain uncertain. We aimed to evaluate if new enteral feeding strategies reflecting early initiation, fortification, and more rapid advancement is beneficial without increasing the risk of NEC.
