Comparison of singleton and twin birth weight reference percentile curves by gestational age and sex in extremely preterm infants: a population-based study.

Background: With the increasing survival rate of smaller newborns and twins, previous growth curves may not accurately assess the growth of extremely preterm infants (EPIs). Our study aimed to establish birth weight percentile curves for singletons and twins in EPIs from China and the USA and compare the differences between them.

Methods: In China, EPIs were from 31 provinces, from 2010 to 2021.

Effect of birth asphyxia on neonatal blood glucose during the early postnatal life: A multi-center study in Hubei Province, China.

Background: Birth asphyxia causes hypoxia or inadequate perfusion to the organs of newborns, leading to metabolism dysfunctions including blood glucose disorders.

Methods: Neonates with and without birth asphyxia were retrospectively recruited from 53 hospitals in Hubei Province from January 1 to December 31, 2018. In summary, 875, 1139, and 180 cases in the control group, the mild asphyxia group, and the severe asphyxia group were recruited, respectively.

A Multicentered Randomized Study on Early versus Rescue Calsurf Administration for the Treatment of Respiratory Distress Syndrome in Preterm Infants.

Objective: Surfactant and noninvasive ventilation are two major strategies for the treatment of neonates with respiratory distress syndrome (RDS). However, the optimal time for surfactant administering is yet controversial. This study compared the early and rescue Calsurf administration in preterm infants with RDS.
