“…Definitions of AGA, SGA, and severe SGA AGA, SGA, and severe SGA were defined as BW or birth length above the 10th percentile (À1.28 SD), between the 10th percentile (À1.28 SD) and À2 SD from the mean, and below À2 SD of the mean value at the same gestational age, respectively [12].…”

“…Small for gestational age (SGA) was defined as a birth weight being more than 2 SD below the mean based on Japanese standard neonatal anthropometric charts [18] . Antenatal steroid use was defined as administration of any corticosteroid to accelerate fetal maturity with at least 1 dose.…”

Background: A high proportion of extremely preterm (EPT) infants are born by cesarean section (CS). However, whether the mode of delivery is related to long-term neurodevelopment in these infants is unclear. Objectives: This study aimed to determine whether the mode of delivery is associated with mortality and long-term outcomes in EPT infants. Methods: We analyzed data of the Neonatal Research Network in Japan (NRNJ), a population-based, nationwide registry. Inclusion criteria were neonates who were born between 2003 and 2012 with a gestational age <26 weeks. The primary composite outcome was death before 3 years or neurodevelopmental impairment (NDI) at 3 years. Confounder-adjusted odds ratios (OR) were estimated by logistic generalized linear mixed models, which accounted for clustering within hospitals. Results: 2,138 eligible infants (703 by vaginal delivery [VD] and 1,435 by CS) were identified for primary analysis. The composite outcome of death or NDI was not different between both groups (66.7% by VD and 62.7% by CS, p = 0.075). After multivariate analysis adjusting for confounders, we found that CS did not improve the composite outcome of death or NDI (OR = 0.839, 95% confidence interval = 0.816-1.328, p = 0.742). For secondary outcomes, mortality (OR = 0.824, p = 0.150), NDI (OR = 1.237, p = 0.165), and other neurodevelopmental outcomes were not different between the groups. Conclusions: Among neonates born at <26 weeks, CS does not improve mortality and neurodevelopmental outcomes at 3 years in the NRNJ cohort. However, because of several potential biases such as high rates of infants lost to follow-up, further evidence may be required.

“…SGA infants were classified as those with a neonatal birth weight lower than the 10th percentile based on the standard build for Japanese births [8] during the gestational period. The z-score for the placental weight at delivery was calculated according to the method described in our previous study [9].…”

Aims: To clarify whether ultrasonographic measurements of crown-rump length (CRL) at 11-13 weeks - based on the number of gestational days determined using the CRL at 9 weeks - can predict fetal prognosis. Methods: A prospective cohort study was conducted to evaluate the association between fetal growth in the first trimester and fetal prognosis. Fetal growth in the first trimester was evaluated measuring CRLs at 11-13 weeks determined using the CRL at 9 weeks. The subjects were divided into short CRL (s-CRL) and normal CRL (n-CRL). The prognoses were compared between the two groups. Results: A total of 126 patients in the s-CRL group and 1,130 patients in the n-CRL group were enrolled. Abortion occurred in 7.1% of s-CRL and 0.9% of n-CRL subjects (p < 0.001). Among the patients with chromosomal abnormalities, the incidence of trisomy 18 was significantly greater in s-CRL (4.8 vs. 0.1%, p < 0.001). Without abortion, placental weight, frequency of small for gestational age (SGA) and birth weight in s-CRL were significantly higher than those in the n-CRL group (12.8 vs. 3.6%, p < 0.001). Conclusions: Measuring CRL at 9 weeks is useful for determining gestational days prior to measuring CRL at 11-13 weeks. After reconfirming the gestational age at 9 weeks, measuring CRL at 11-13 weeks is useful for predicting the incidence of trisomy 18 as well as SGA later in pregnancy.
