Objective: We characterize the most recent natural history of necrotizing enterocolitis (NEC), as this is an essential first step in guiding the prevention and treatment of this disease in the present day.
Study Design: We performed a retrospective cohort study of neonates who were born at 23 to 29 weeks' gestation and birth weight <1,500 g who received care from the Pediatrix Medical Group between 2004 and 2019. We assessed the incidence of medical and surgical NEC and the patterns of initial antibiotic treatment to develop a contemporary cohort for further analysis. Among patients discharged between 2015 and 2019, we characterized the stage-specific risk factors for patients diagnosed with medical or surgical NEC, as well as patterns of disease onset, progression, biomarkers, and outcomes. We used the same approach to characterize patients diagnosed with suspected NEC.
Results: Among 34,032 patients in the contemporary cohort, 1,150 (3.4%) were diagnosed with medical NEC and 543 (1.6%) were diagnosed with surgical NEC. The temporal pattern of disease onset was different for medical and surgical NEC, with gestational age- and birth weight-specific risk disparities emerging earlier in surgical NEC. Thirty-day mortality was much greater among surgical NEC patients (medical NEC 16.4% vs. surgical NEC 43.0%), as were rates of various in-hospital and long-term outcomes. Suspected NEC was diagnosed in 1,256 (3.7%) patients, among whom risk factors and disease onset, progression, and outcomes closely resembled those of medical NEC.
Conclusion: Analyzing data from a contemporary cohort enabled us to characterize the current, stage-specific natural history of NEC, including novel insights into suspected NEC. Future studies could leverage this cohort to characterize how specific patient characteristics, care processes, or biomarkers may influence or predict disease outcomes.
Key Points: · The incidence of NEC has reached a stable baseline in recent years.. · Risk factors for NEC vary in a stage-specific manner.. · The stage-specific onset and progression of NEC differ by gestational age and birth weight..

Although the role of breast milk in promoting neonatal growth and maintaining intestinal homeostasis is well established, underlying mechanisms by which it protects the intestine from damage remain to be elucidated. Human breast milk-derived exosomes (HMDEs) are newly discovered active signaling vesicles with a diameter of 30-150 nm, which are key carriers of biological information exchange between mother and child. In addition, due to their ability to cross the gastrointestinal barrier, low immunogenicity, good biocompatibility and stability, HMDEs play an important role in regulating intestinal barrier integrity in newborns.

This study investigated the correlation between quantitative echocardiographic characteristics within 3 days of birth and necrotizing enterocolitis (NEC) and its severity in preterm infants. A retrospective study was conducted on 168 preterm infants with a gestational age of < 34 weeks. Patients were categorized into NEC and non-NEC groups.

L-citrulline (L-CIT), a precursor to L-arginine (L-ARG), is a key contributor to the nitric oxide (NO) signaling pathway. Endothelial dysfunction, characterized by deficient nitric oxide synthesis, is implicated in the pathogenesis of various neonatal conditions such as necrotizing enterocolitis (NEC) and bronchopulmonary dysplasia (BPD) associated pulmonary hypertension (PH). This review summarizes the current evidence around the possible role of L-CIT supplementation in the treatment of these conditions.

Objective: To evaluate the label accuracy of commercial infant probiotic products and identify potential microbial contamination.
Methods: DNA was extracted from seventeen infant probiotic products purchased from a large online vendor. Samples underwent 16S ribosomal RNA gene sequencing, QIIME analysis, and bacterial taxonomic classification.

Objective: To characterize the association between maternal ethnicity and infant survival to discharge without major morbidity.
Study Design: This is secondary analysis of a prospective cohort of infants born <27 weeks of gestation at NICHD Neonatal Research Network centers from 2006 through 2020. The primary outcome was survival to discharge without major morbidity (sepsis, necrotizing enterocolitis, bronchopulmonary dysplasia grade 3, intracranial hemorrhage grade ≥3, periventricular leukomalacia, and advanced retinopathy of prematurity).
