Abstract
OBJECTIVE Determine association between time to regain birthweight and 2-year neurodevelopment among extremely preterm (EP) newborns. STUDY DESIGN Secondary analysis of the Preterm Erythropoietin Neuroprotection Trial evaluating time to regain birthweight, time from birth to weight nadir, time from nadir to regain birthweight, and cumulative weight loss with 2-year corrected Bayley Scales of Infant and Toddler Development 3rd edition. RESULTS Among n = 654 EP neonates, those with shorter nadir-to-regain had lower cognitive scores (≤1 day versus ≥8 days: -5.0 points, [CI -9.5, -0.6]) and lower motor scores (≤1 day versus ≥8 days: -4.6 points [CI -9.2, -0.03]) in adjusted stepwise forward regression modeling. Increasingly cumulative weight loss was associated with lower cognitive scores (≤-50 percent-days: -5.6, [CI -9.4, -1.8]), motor scores (≤-50 percent-days: -4.2, [CI -8.2, -0.2]); and language scores (≤-50 percent-days: -6.0, [CI -10.1, -1.9]). CONCLUSION Faster nadir-to-regain and excessive cumulative weight loss are associated with adverse 2-year neurodevelopmental outcomes. TRIAL REGISTRATION PENUT Trial Registration: NCT01378273. https://clinicaltrials.gov/ct2/show/NCT01378273 . CLINICAL TRIAL REGISTRATION This study is a post-hoc secondary analysis of pre-existing data from the PENUT Trial (NCT #01378273).

Abstract
Despite advances in neonatal nutrition, very preterm infants remain at increased risk of extrauterine growth faltering. This prospective study aimed to examine the effect of hindmilk, the milk at the end of a breast expression session, on growth and plasma fatty acids (FAs) of infants born <30 weeks' gestation who had been on full enteral feeds for ≥2 weeks and had a weight gain of <15 g/kg/day despite optimizing energy and protein intakes. Weight and plasma FAs were assessed before and two weeks after feeding hindmilk. Growth anthropometrics were assessed weekly for four weeks. Paired t-tests and multiple linear regression were used for statistical analyses of data from 34 infants and their 29 mothers. There was a significant increase in weight gain in the two weeks after feeding hindmilk (MD 3.9, 95%CI 1.2-6.5 g/kg/day). Weight Z-scores were larger at two weeks (MD 0.61, 95%CI 0.02-1.20) and onwards. Head circumference Z-scores were larger at three weeks (MD 0.83, 95%CI 0.20-1.47) and onwards. Plasma linoleic acid (LA) and α-linolenic acid (ALA) increased after feeding hindmilk. In conclusion, hindmilk may improve weight and head growth and increase LA and ALA in very preterm infants with suboptimal growth. A large randomized controlled trial is required to examine and validate the potential benefits of hindmilk.

Abstract
OBJECTIVES Preterm delivery (<37 weeks gestation) is the largest cause of child mortality worldwide. Marriage and pregnancy during adolescence have been associated with an increased risk of preterm delivery. We investigate independent associations of age at marriage and age at first pregnancy with preterm delivery in a cohort of women from rural lowland Nepal. METHODS We analyzed data from 17 974 women in the Low Birth Weight South Asia Trial. Logistic regression models tested associations of age at marriage and age at first pregnancy with preterm delivery, for primigravida (n = 6 243) and multigravida (n = 11 731) women. Models were adjusted for maternal education, maternal caste, and household asset score. RESULTS Ninety percent of participants had married at <18 years and 58% had their first pregnancy at <18 years. 20% of participants delivered preterm. Primigravida participants married at ≤14 years had higher odds of preterm delivery than those married ≥18 years, when adjusting for study design (adjusted odds ratio (aOR) 1.45, 95% CI: 1.15-1.83), confounders (aOR 1.28: 1.01-1.62) and confounders + age at pregnancy (aOR 1.29: 1.00-1.68). Associations were insignificant for multigravida women. No significant associations were observed between age at first pregnancy and preterm delivery. DISCUSSION In this population, early marriage, rather than pregnancy, is a risk factor for preterm delivery. We hypothesize that psychological stress, a driver of preterm delivery which is increased among those marrying young, rather than physiological immaturity, drives this association. Further research into the psychological consequences of child marriage in Nepal is needed.

Abstract
OBJECTIVE Extrauterine growth restriction (EUGR) among very preterm infants is related to poor neurodevelopment, but lack of consensus on EUGR measurement constrains international research. Our aim was to compare EUGR prevalence in a European very preterm cohort using commonly used measures. DESIGN Population-based observational study. SETTING 19 regions in 11 European countries. PATIENTS 6792 very preterm infants born before 32 weeks' gestational age (GA) surviving to discharge. MAIN OUTCOME MEASURES We investigated two measures based on discharge-weight percentiles with (1) Fenton and (2) Intergrowth (IG) charts and two based on growth velocity (1) birth weight and discharge-weight Z-score differences using Fenton charts and (2) weight-gain velocity using Patel's model. We estimated country-level relative risks of EUGR adjusting for maternal and neonatal characteristics and associations with population differences in healthy newborn size, measured by mean national birth weight at 40 weeks' GA. RESULTS About twofold differences in EUGR prevalence were observed between countries for all indicators and these persisted after case-mix adjustment. Discharge weight <10th percentile using Fenton charts varied from 24% (Sweden) to 60% (Portugal) and using IG from 13% (Sweden) to 43% (Portugal), while low weight-gain velocity ranged from 35% (Germany) to 62% (UK). Mean term birth weight strongly correlated with both percentile-based measures (Spearman's rho=-0.90 Fenton, -0.84 IG, p<0.01), but not Patel's weight-gain velocity (rho: -0.38, p=0.25). CONCLUSIONS Very preterm infants have a high prevalence of EUGR, with wide variations between countries in Europe. Variability associated with mean term birth weight when using common postnatal growth charts complicates international benchmarking.

Abstract
OBJECTIVE Amidst a high prevalence of prematurity, limited research on the growth of very low birth weight (VLBW) preterm infants and the availability of a reformulated fortifier c(RF), the study aimed to compare in-hospital growth of such infants receiving exclusively human milk fortified with either of 2 different formulations in a tertiary South African hospital. METHODS In a prospective comparative effectiveness design, intakes and growth of VLBW infants on the Original Fortifier (OF; 2016-2017) were compared with those receiving RF (2017-2018). Daily intake was calculated using published composition of preterm and mature milk with fortifier (OF: 0.2 g protein, 3.5kcal/g powder; RF: 0.4 g protein, 4.4 kcal/g powder). Change in z scores from start to end of fortification for weight (WFAZ), length (LFAZ), and head circumference (HCFAZ) for age was the primary outcome. Additionally, weight gain velocity (g · kg-1 · day-1) and gain in length and head circumference (HC) (cm/week) were calculated. RESULTS Fifty-eight infants (52% girls; gestational age: 30 ± 2 weeks; birth weight: 1215 ± 187 g) received OF for 16 days and 59 infants (56% girls; gestational age: 29 ± 2 weeks; birth weight 1202 ± 167 g) received RF for 15 days. Protein intake of RF (3.7 ± 0.4 g · kg-1 · day-1) was significantly higher (P < 0.001) than of OF (3.4 ± 0.2 g · kg-1 · day-1). Protein-to-energy ratio of RF (2.6 ± 0.2 g/100 kcal) was significantly higher (P < 0.001) than of OF (2.3 ± 0.1 g/100 kcal). In both groups, WFAZ and LFAZ decreased; HCFAZ improved slightly. No significant differences (P > 0.05) were noted between the 2 groups for change in z scores, weight gain velocity, length or HC gain. CONCLUSIONS Despite a modest increase in protein intake and protein-to-energy ratio, the growth of VLBW infants on RF was not better than on OF during their hospital stay.

Abstract
Preterm infants are at risk of growth failure and metabolic bone disease due to insufficient nutrient supply in postnatal life. An ample provision of protein, energy, calcium and phosphates through parenteral or/and enteral nutrition is crucial for bone growth and mineralization. Additional vitamin D supplementation improves bone mineralization and enhance intestinal absorption of minerals.
