Background: Community lockdowns during the COVID-19 pandemic may influence preterm birth rates, but mechanisms are unclear. Methods: We compared neonatal outcomes of preterm infants born to mothers exposed to community lockdowns in 2020 (exposed group) to those born in 2019 (control group). Main outcome studied was composite of significant neonatal morbidity or death. Results: Median gestational age was 35+4 weeks (295 infants, exposed group) vs. 35+0 weeks (347 infants, control group) (p = 0.108). The main outcome occurred in 36/295 (12.2%) infants in exposed group vs. 46/347 (13.3%) in control group (p = 0.69). Continuous positive airway pressure (CPAP) use, jaundice requiring phototherapy, hypoglycaemia requiring treatment, early neonatal white cell and neutrophil counts were significantly reduced in the exposed group. Conclusions: COVID-19 community lockdowns did not alter composite neonatal outcomes in preterm infants, but reduced rates of some common outcomes, and early white cell and neutrophil counts.

Objective The objective of this study was to examine the association between umbilical catheters and a composite outcome of mortality or major neonatal morbidity in extremely preterm infants. Study Design Data were abstracted from the Canadian Neonatal Network database for infants born at <29 weeks' gestational age and admitted to 29 neonatal intensive care units between January 2010 and December 2012. Four groups were identified: those with no umbilical catheters, umbilical venous catheters (UVCs), umbilical artery catheters (UACs), and those with both UVCs and UACs. The outcomes were compared among the groups using univariate and multivariable analyses. Results Of 4,623 eligible infants, 820 (17.7%) had no catheters, 1,032 (22.3%) a UVC only, 120 (2.6%) a UAC only, and 2,651 (57.3%) had both catheters. After adjustment for acuity and other potential confounders, umbilical catheters were associated with higher odds of mortality or any major morbidity (UVC vs. no catheter: adjusted odds ratio [aOR]: 1.47; 95% CI: 1.18–1.85; UAC vs. no catheter: aOR: 1.67; 95% CI: 1.05–2.63; and both UVC + UAC vs. no catheter: aOR: 2.17; 95% CI: 1.79–2.70). Conclusion Most of the infants born at <29 weeks' gestation had UVC and/or UAC placement. The presence of either catheter was associated with mortality or major morbidity, and the association was stronger when both catheters were present.

ObjectiveTo characterise the excess risk for death, grade 3–4 intraventricular haemorrhage (IVH), bronchopulmonary dysplasia (BPD) and stage 3–5 retinopathy of prematurity independently associated with birth small for gestational age (SGA) among very preterm infants, stratified by completed weeks of gestation.MethodsRetrospective cohort study using the Optum Neonatal Database. Study infants were born <32 weeks gestation without severe congenital anomalies. SGA was defined as a birth weight <10th percentile. The excess outcome risk independently associated with SGA birth among SGA babies was assessed using adjusted risk differences (aRDs).ResultsOf 6708 infants sampled from 717 US hospitals, 743 (11.1%) were SGA. SGA compared with non-SGA infants experienced higher unadjusted rates of each study outcome except grade 3–4 IVH among survivors. The excess risk independently associated with SGA birth varied by outcome and gestational age. The highest aRD for death (0.27; 95% CI 0.13 to 0.40) occurred among infants born at 24 weeks gestation and declined as gestational age increased. In contrast, the peak aRDs for BPD among survivors (0.32; 95% CI 0.20 to 0.44) and the composites of death or BPD (0.35; 95% CI 0.24 to 0.46) and death or major morbidity (0.35; 95% CI 0.24 to 0.45) occurred at 27 weeks gestation. The risk-adjusted probability of dying or developing one or more of the evaluated morbidities among SGA infants was similar to that of non-SGA infants born approximately 2–3 weeks less mature.ConclusionThe excess risk for neonatal morbidity and mortality associated with being born SGA varies by adverse outcome and gestational age.

Abstract Background Infants born very preterm are more likely to experience neonatal morbidities compared to their term peers. Variations in DNA methylation (DNAm) associated with these morbidities may yield novel information about the processes impacted by these morbidities. Methods This study included 532 infants born < 30 weeks gestation, participating in the Neonatal Neurobehavior and Outcomes in Very Preterm Infants study. We used a neonatal morbidity risk score, which was an additive index of the number of morbidities experienced during the NICU stay, including bronchopulmonary dysplasia (BPD), severe brain injury, serious neonatal infections, and severe retinopathy of prematurity. DNA was collected from buccal cells at discharge from the NICU, and DNAm was measured using the Illumina MethylationEPIC. We tested for differential methylation in association with the neonatal morbidity risk score then tested for differentially methylated regions (DMRs) and overrepresentation of biological pathways. Results We identified ten differentially methylated CpGs (α Bonferroni-adjusted for 706,278 tests) that were associated with increasing neonatal morbidity risk scores at three intergenic regions and at HPS4, SRRD, FGFR1OP, TNS3, TMEM266, LRRC3B, ZNF780A, and TENM2. These mostly followed dose–response patterns, for 8 CpGs increasing DNAm associated with increased numbers of morbidities, while for 2 CpGs the risk score was associated with decreasing DNAm. BPD was the most substantial contributor to differential methylation. We also identified seven potential DMRs and over-representation of genes involved in Wnt signaling; however, these results were not significant after Bonferroni adjustment for multiple testing. Conclusions Neonatal DNAm, within genes involved in fibroblast growth factor activities, cellular invasion and migration, and neuronal signaling and development, are sensitive to the neonatal health complications of prematurity. We hypothesize that these epigenetic features may be representative of an integrated marker of neonatal health and development and are promising candidates to integrate with clinical information for studying developmental impairments in childhood.
