Background: To construct a nomogram for predicting necrotizing enterocolitis (NEC) in preterm infants.

Methods: A total of 4,724 preterm infants who were admitted into 8 hospitals between April 2019 and September 2020 were initially enrolled this retrospective multicenter cohort study. Finally, 1,092 eligible cases were divided into training set and test set based on a 7:3 ratio.

Risk factors of necrotizing enterocolitis in twin preterm infants.

Purpose: This study was aimed to investigate the risk factors of necrotizing enterocolitis (NEC) in twin preterm infants.

Methods: The clinical data of 67 pairs of twin preterm infants admitted to the neonatal department of our hospital from January 2010 to December 2021 were retrospectively collected. One of the twins had NEC (Bell II and above) and the other twin without NEC.

Values of serum intestinal fatty acid-binding protein, fecal calprotectin, and fecal human β-defensin 2 for predicting necrotizing enterocolitis.

Background: This study aimed to assess the diagnostic potential of serum intestinal fatty acid-binding protein (I-FABP), fecal calprotectin (FC), and fecal human β-defensin 2 (hBD2) in predicting necrotizing enterocolitis (NEC) in preterm infants.

Methods: A prospective cohort of neonates with a gestational age < 32 weeks, suspected of NEC, was enrolled between June 2021 and December 2022. Serum I-FABP, FC, and fecal hBD2 levels were measured upon NEC suspicion, and diagnosis was confirmed through radiological examination or surgical intervention.

Effects of hypertensive disorders of pregnancy on the complications in very low birth weight neonates.

Objective: This study was designed to investigate the effects of hypertensive disorders of pregnancy (HDP) on the complications in very low birth weight (VLBW) neonates.

Methods: We retrospectively included VLBW neonates (<37 weeks) who were delivered by HDP pregnant women with a body weight of < 1,500 g (HDP group) hospitalized in our hospital between January 2016 and July 2021. Gestational age matched VLBW neonates delivered by pregnant women with a normal blood pressure, with a proportion of 1:1 to the HDP group in number, served as normal control.

Assessing multiple factors affecting the gut microbiome structure of very preterm infants.

The composition and diversity of the gut microbiota are essential for the health and development of the immune system of infants. However, there is limited information on factors that influence the gut microbiota of very preterm infants. In this study, we analyzed factors that affect the gut microbiota of very preterm infants.

Cerebral and intestinal oxygen saturation of different volumes of red blood cell transfusion in preterm infants.

Objectives: The purpose of this study was to investigate and compare the effects of 20 ml/kg and 15 ml/kg red blood cell transfusion (RBCT) on cerebral and intestinal tissue oxygenation, the number of administered transfusions, and neonatal complications in premature infants with anemia.

Methods: This prospective, randomized, partially blinded observational study investigated anemic neonates of gestational age < 32 weeks (Registration ID: ChiCTR 1,900,026,672). The infants were randomly assigned to receive 15 or 20 ml/kg red blood cell transfusion.

Status of the neonatal follow-up system in China: survey and analysis.

Background: There is little information about neonatal follow-up programs (NFUPs) in China. This study aimed to conduct a survey of hospitals participating in the Chinese Neonatal Network (CHNN) to determine the status of NFUPs, including resources available, criteria for enrollment, neurodevelopmental assessments, and duration of follow-up.

Methods: We conducted a descriptive study using an online survey of all 72 hospitals participating in CHNN in 2020.

Application of High-Frequency Oscillation Ventilation Combined With Volume Guarantee in Preterm Infants With Acute Hypoxic Respiratory Failure After Patent Ductus Arteriosus Ligation.

Objective: This study aimed to evaluate the efficacy and safety of high-frequency oscillation ventilation combined with volume guarantee (HFOV-VG) in preterm infants with acute hypoxemic respiratory failure (AHRF) after patent ductus arteriosus ligation.

Methods: We retrospectively analyzed the clinical data of 41 preterm infants, who were ventilated for AHRF after patent ductus arteriosus ligation between January 2020 and January 2022. HFOV alone was used in 20 of the 41 infants, whereas HFOV-VG was used in the other 21 infants.

Discharge against medical advice among infants with 24-31 weeks' gestation admitted to Chinese neonatal intensive care units: A multicenter cohort study.

Background: Previous studies demonstrated high rates of discharge against medical advice (DAMA) among very preterm infants (VPIs) in China.

Objectives: The aim of this study was to investigate the concurrent incidence, variation, and predictors of DAMA, along with the effect of DAMA on mortality of VPIs in China using data from the Chinese Neonatal Network (CHNN).

Methods: All infants born at 24-31 completed weeks' gestation and admitted to 57 CHNN neonatal intensive care units (NICUs) in 2019 were included for this cohort study, excluding infants with major congenital anomalies.

Oropharyngeal administration of colostrum for preventing necrotizing enterocolitis and late-onset sepsis in preterm infants with gestational age ≤ 32 weeks: a pilot single-center randomized controlled trial.

Background: Oropharyngeal administration of colostrum (OAC) may provide immunoprotective and anti-inflammatory effects that potentially reduce the incidence of necrotizing enterocolitis (NEC) and late-onset sepsis and improve short-term outcomes. Our objective was to evaluate the role of OAC in the early prevention of NEC and late-onset sepsis in preterm infants with gestational age (GA) ≤ 32 weeks.

Methods: A pilot, single-center, 1:1 parallel randomized controlled trial was conducted in a 40-bed tertiary neonatal intensive care unit (NICU) in China from 1 January 2019 to 30 September 2020.

Protective effects of different doses of human milk on neonatal necrotizing enterocolitis.

We aim to summarize the evidence focusing on the effects of various doses of human milk on the risk of neonatal necrotizing enterocolitis (NEC). The eligible articles in the study were those investigating the association between human milk and NEC published before June 26, 2019, in the PubMed, EMBASE, the Cochrane Library, VIP database, CNKI database, and Wangfang database. The included criteria were as follows: premature infants of <37 weeks; randomly controlled trials (RCTs); those fed by mother's own milk or donor human milk; studies focused on the comparison of human milk and formula milk, involving various breast milk doses; and NEC-related studies.

Long-term effects of the intratracheal administration of corticosteroids for the prevention of bronchopulmonary dysplasia: A meta-analysis.

Background: Bronchopulmonary dysplasia (BPD) is one of the most common complications in premature infants. Since inflammation plays a crucial role in the pathogenesis of BPD, anti-inflammatory drugs, such as corticosteroids, have long been the focus of prevention research. In this meta-analysis, we aim to explore the long-term effects of the intratracheal administration of corticosteroids (IAC) in preventing BPD.

Mutation of glucose-6-phosphate dehydrogenase deficiency in Chinese Han children in eastern Fujian.

We aim to investigate the mutation types of glucose-6-phosphate dehydrogenase (G6PD) deficiency in Chinese Han children in eastern Fujian Province.A total of 904 Chinese Han neonates (male: 733 with positive G6PD deficiency and 28 with weakly positive deficiency; female: 73 with positive G6PD deficiency and 70 with weakly positive deficiency) received G6PD screening in our center from January 2014 to December 2016 were included in this study. Additionally, 904 age-matched normal Chinese Han individuals (male: 761; female: 143) were selected as control.

A decrease in the number of cases of necrotizing enterocolitis associated with the enhancement of infection prevention and control measures during a Staphylococcus aureus outbreak in a neonatal intensive care unit.

Objective: Most cases of necrotizing enterocolitis (NEC) are sporadic, but outbreaks in hospital settings suggest an infectious cause. Our neonatal intensive care unit (NICU) experienced an outbreak of methicillin-sensitive Staphylococcus aureus (MSSA). We aimed to assess whether the enhancement of infection prevention and control measures would be associated with a reduction in the number of cases of NEC.
