Necrotizing enterocolitis (NEC), a serious gastrointestinal inflammatory disease, frequently occurs in preterm neonates that fail to adapt to enteral nutrition. A temporal gel-based proteomics study was performed on porcine intestine with NEC lesions induced by enteral formula feeding. Functional assignment of the differentially expressed proteins revealed that important cellular functions, such as the heat shock response, protein processing; and purine, nitrogen, energy metabolism, were possible involved in the early progression of NEC.

Visceral Pain in Preterm Infants with Necrotizing Enterocolitis: Underlying Mechanisms and Implications for Treatment.

Necrotizing enterocolitis (NEC) is a relatively rare but very severe gastrointestinal disease primarily affecting very preterm infants. NEC is characterized by excessive inflammation and ischemia in the intestines, and is associated with prolonged, severe visceral pain. Despite its recognition as a highly painful disease, current pain management for NEC is often inadequate, and research on optimal analgesic therapy for these patients is lacking.

Background: Enteral feeding of preterm infants with maternal colostrum has well-known effects on protecting them, especially against serious infections. This study was conducted to determine whether oropharyngeal administration of colostrum to these infants, soon after birth, has any additional effect on their clinical outcomes and stimulation of their immune system.
Methods: In this double-blind randomized clinical trial, 60 preterm infants ≤30 weeks' gestation with birth weight ≤1500 g were randomly assigned to receive oropharyngeal colostrum (OAC group) or distilled water (DW group).
Introduction Respiratory distress syndrome (RDS) is a leading cause of morbidity and mortality among preterm infants, necessitating effective treatment strategies. This study compared the efficacy of Beractant (SURVANTA®) to Poractant alfa (CUROSURF®) in treating RDS in preterm infants admitted to Tawam Hospital in the UAE. Methodology This retrospective study included preterm infants from 23+0 to 36+6 weeks of gestation with a diagnosis of RDS and treatment by Beractant or Poractant alfa within 48 hours of life between January 2020 and March 2023.

Background: The neonatal Sequential Organ Failure Assessment (nSOFA) score is an organ dysfunction score developed for predicting mortality risk in preterm neonates with proven late-onset neonatal sepsis (LONS) and necrotising enterocolitis. However, the utility of the nSOFA score in determining the risk of retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD) or mortality in patients with suspected LONS is unknown.
Methods: We performed a dual-centre retrospective cohort study of preterm (gestational age <32 weeks) neonates suspected of LONS, from 2016 to 2020 at two neonatal intensive care units.

Introduction: High mortality and morbidity of neonates with necrotizing enterocolitis (NEC) necessitates the investigation of novel therapies to improve outcomes. It was aimed to elucidate the potential therapeutic effect of estrogen receptor agonists on NEC-induced intestinal and brain injury in rats.
Methods: Sprague-Dawley pups of both sexes were separated from their mothers at postnatal 5 d.
