J Matern Fetal Neonatal Med 2024; 37:2381584. [PMID: 39034273 DOI: 10.1080/14767058.2024.2381584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Accepted: 07/14/2024] [Indexed: 07/23/2024]
Abstract
OBJECTIVE To explore the complications and pregnancy outcomes of vaginal dinoprostone vs. Cook's double balloon for the induction of labor among pregnancies complicated by small-for-gestational-age (SGA) at term. METHODS This retrospective study included consecutive singleton pregnancies complicated by SGA treated at Fujian Maternity and Child Health Hospital between January 2017 and December 2021. The patients were divided into the Cook's double balloon and dinoprostone groups according to the induction method they received. The primary outcome was vaginal delivery. RESULTS This study included 318 women [165 (aged 30.25 ± 4.72 years) and 153 (aged 28.80 ± 3.91 years) in the dinoprostone and Cook's balloon groups]. The dinoprostone group had a higher vaginal delivery rate than the Cook's balloon group (83.6% vs. 71.9%, p = .012). The cervical ripening duration (9.73 ± 4.82 vs. 17.50 ± 8.77 h, p < .001) and induction to delivery duration (22.11 ± 8.13 vs. 30.27 ± 12.28, p < .001) were significantly shorter in the dinoprostone group compared with the Cook's balloon group. Less women needed oxytocin infusion in the dinoprostone group compared with that in the Cook's balloon group (32.7% vs. 86.3%, p < .001). Dinoprostone was independently associated with vaginal delivery (HR = 1.756, 95%CI: 1.286-2.399, p = .000). The rates of uterine tachysystole and spontaneous rupture of the fetal membrane were significantly higher in the dinoprostone group than that in the Cook's balloon group (10.3% vs. 0.7%, p < .001; 7.3% vs. 1.3%, p = .012). There were no differences in maternal complications and neonatal outcomes between the two groups. CONCLUSION In pregnant woman with pregnancies complicated by SGA, cervical ripening using dinoprostone were more likely to achieve vaginal delivery than those with Cook's balloon, and with a favorable complication profile.

Abstract
BACKGROUND Progestin-only pills (POPs) have been used for contraception in breastfeeding women for years. The existing guidelines allow the use of these contraceptives. METHODS Multicenter study with a single visit and retrospective data review. The study involved 100 women who used a drospirenone-only pill (DRSP) for contraception for at least 5 months during breastfeeding. The study aimed to analyze for those successful users the impact on new-born development, the bleeding profile and evaluate user satisfaction. RESULTS Analysis of the newborns showed that their growth parameters length and weight, were within the expected range of standard development. The mean birth weight was 3368 g, with the lowest recorded weight being 2860 g and the highest 5040 g. The median length of the newborns was 55 cm, ranging from 35 to 65 cm. All new-borns demonstrated appropriate growth within the established percentiles. Acceptability with the bleeding profile was rated with a VAS score: the mean acceptability rating was 82.8. Women aged 35 years or older reported significantly higher acceptability compared to younger women (≥35 years: mean = 88.4, SD = 16.5; <35 years: mean = 80.3, SD = 20.2) (p = 0.02). Sixty-one patients (N = 61; 61.0%; 95% CI: 50.7 - 70.4%) expressed willingness to continue using DRSP after breastfeeding. CONCLUSION Among those patients who continued the use of the DRSP only-pill for 5 months, this study shows no negative impact for new-borns, with no clinical influence observed on their growth. Additionally, those users expressed high satisfaction with the bleeding profile of the pill.Clinical trial registration number: DRKS00028438 .

Abstract
5-hydroxymethylcystosine (5hmC), is an intermediate product in the DNA demethylation pathway, but may act as a functional epigenetic modification. We have conducted the largest study of site-specific 5hmC in placenta to date using parallel bisulphite and oxidative bisulphite modification with array-based assessment. Incorporating parallel RNA-sequencing data allowed us to assess associations between 5hmC and gene expression, using expression quantitative trait hydroxymethylation (eQTHM) analysis. We identified ~ 47,000 loci with consistently elevated (systematic) 5hmC proportions. Systematic 5hmC was significantly depleted (p < 0.0001) at CpG islands (CGI), and enriched (p < 0.0001) in 'open sea' regions (CpG >4 kb from CGI). 5hmC was most and least abundant at CpGs in enhancers and active transcription start sites (TSS), respectively (p < 0.05). We identified 499 significant (empirical-p <0.05) eQTHMs within 1 MB of the assayed gene. At most (75.4%) eQTHMs, the proportion of 5hmC was positively correlated with transcript abundance. eQTHMs were significantly enriched among enhancer CpGs and depleted among CpGs in active TSS (p < 0.05 for both). Finally, we identified 107 differentially hydroxymethylated regions (DHMRs, p < 0.05) across 100 genes. Our study provides insight into placental distribution of 5hmC, and sheds light on the functional capacity of this epigenetic modification in placenta.

Abstract
AIM This study aimed to address the critical need for more accurate growth reference charts for preterm infants, with a particular focus on low- and very low-birth-weight infants. METHODS The subjects were recruited at a single tertiary centre. The cohort comprised singleton and twin infants born before 37 weeks of gestation, with data collected from 2000 to 2016. Standardised measurements of body parameters were recorded in this mixed longitudinal survey. LMS method was utilised for data analysis. Statistical analysis was performed using SPSS Statistics Version 21. The validation with another new cohort was executed. RESULTS A total of 1781 infants (52.5% boys) met the inclusion criteria. The median gestational age at birth was 30 weeks, with a median birth weight of 1350 grams. The main findings included the construction of ImaGrow charts for low- and very low-birth-weight infants and significant differences in growth trajectories compared to Fenton+WHO charts. CONCLUSION Our comprehensive growth references, ImaGrow, are based on a long-term auxological assessment of preterm infants and differ from charts derived from size-at-birth standards or charts for term babies. These charts have significant implications for clinical practice in monitoring and assessing the growth of preterm infants.

Influence of morbidity, early nutritional intake, and total energy: protein ratio on longitudinal extrauterine growth restriction of very preterm newborns at term-equivalent age: an observational study. Eur J Pediatr 2024; 183:3327-3336. [PMID: 38730194 DOI: 10.1007/s00431-024-05595-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/13/2024] [Accepted: 05/01/2024] [Indexed: 05/12/2024]
Abstract
To evaluate the influence of early nutritional intake on the growth pattern of very preterm infants. This was an observational study including 109 newborns (< 32 weeks gestational age). Perinatal morbidities, nutritional therapy (first four weeks of life), and weight, length, and head circumference (HC) growth at term-equivalent age were evaluated. Growth restriction was defined as a difference > 1.2 SD between the birth and term age measurements. Growth restriction at term-equivalent age: 52.3% (weight), 42.9% (length), and 22% (HC). Morbidities were positively correlated with nutrition therapy and negatively correlated with the total energy provision: protein ratio. The duration of parenteral nutrition, the time to reach full enteral feedings, and the total energy provision: protein ratio were significantly correlated. Nutrient intake influenced weight, length, and HC growth, and cumulative energy deficit was significantly associated with HC growth restriction. Conclusion: Perinatal morbidities interfere with nutritional therapy and early nutrient intake, leading to insufficient energy and energy provision: protein ratio for growth. What is Known: • The intake of macronutrients early in life, mainly protein, is important for the optimal growth of pretem infants. • The severity of morbidities and low gestational ages impact the nutritional management of preterm infants. What is New: • The number of morbidities, reflecting the severity of the neonatal clinical course, had a detrimental effect on the nutritional therapy and nutrients intake. • The inadequate energy provision per gram of protein ratio was significantly associated with growth restriction in all growth measures at the second week of life, persisting for head circumference up to the fourth week, highlighting the importance of its measurement, as it could be a precocious sign of development risk.

Abstract
OBJECTIVE To evaluate associations between change in weight z score after neonatal intensive care unit (NICU) discharge and neurodevelopmental outcomes and obesity at 12-48 months of age among individuals born very preterm. STUDY DESIGN This secondary analysis used data from infants born very preterm participating in the Environmental influences on Child Health Outcomes cohort (n = 1400). Growth during infancy was calculated as change in weight z score between NICU discharge and follow-up at a mean of 27 months of age. Very low weight gain was defined as a change in weight z score <-1.67; very high weight gain was a change in weight z score >1.67. Neurodevelopmental outcomes included the Bayley Scales of Infant and Toddler Development, Child Behavior Checklist 1.5-5 years, and Modified Checklist for Autism in Toddlers. Multivariable linear regression was used to estimate associations between increase in weight z score and neurodevelopmental outcomes. RESULTS Very low weight gain between NICU discharge and follow-up (experienced by 6.4% of participants) was associated with lower scores on cognitive (adjusted mean difference: -4.26; 95% CI: -8.55, -0.04) and language (adjusted mean difference: -4.80; 95% CI: -9.70, -0.11) assessments. Very high weight gain (experienced by 13.6% of participants) was associated with an increased obesity risk (adjusted relative risk: 6.20; 95% CI: 3.99, 9.66) but not with neurodevelopmental outcomes. CONCLUSIONS Very high weight gain in the first 12-48 months after NICU discharge was associated with a higher risk of obesity at follow-up; very low weight gain was associated with lower scores on cognitive and language assessments.

Abstract
OBJECTIVE To evaluate if antenatal steroid use was associated with a lower rate of respiratory complications in neonates born late preterm to patients with pregestational diabetes mellitus (PGDM). METHODS This was a retrospective cohort study of live, singleton, non-anomalous, late preterm births complicated by PGDM using data from the Centers for Disease Control and National Vital Statistics System from 2017 to 2021. The primary (assisted ventilation use >6 h) and secondary neonatal outcomes (immediate assisted ventilation, Apgar score, neonatal intensive care unit [NICU] admission, and surfactant use) were compared between births that received steroids and those that did not. Multivariable analyses were performed to adjust for differences in demographic and clinical characteristics. RESULTS There were 24 323 late preterm births with PGDM, of which 4613 received antenatal steroids and 19 710 did not receive steroids. After adjusting for the differences among the two groups, the need for assisted neonatal ventilation for more than 6 h (adjusted odds ratio [aOR] 1.69, 95% confidence interval [CI] 1.53-1.86), immediate assisted neonatal ventilation (aOR 1.67, 95% CI 1.55-1.80), NICU admission (aOR 1.95, 95% CI 1.81-2.10), and surfactant use (aOR 1.68, 95% CI 1.40-2.02) were higher in the births that received steroids compared with those that did not. These findings did not differ when examining outcomes at each gestational week of delivery between 34 weeks 0 days and 36 weeks 6 days. CONCLUSIONS Antenatal steroid use in late preterm births complicated with PGDM was associated with worse immediate respiratory neonatal outcomes. Our findings support current recommendations against the use of steroids in the late preterm period in pregnancies with PGDM.

Mortality and extrauterine growth restriction of necrotizing enterocolitis in very preterm infants with heart disease: a multi-center cohort study. Eur J Pediatr 2024; 183:3579-3588. [PMID: 38822834 DOI: 10.1007/s00431-024-05599-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/28/2024] [Accepted: 05/03/2024] [Indexed: 06/03/2024]
Abstract
Congenital heart disease (CHD) and patent ductus arteriosus (PDA) are risk factors of necrotizing enterocolitis (NEC) in infants. However, it is unclear whether the prognosis of NEC is different between very preterm infants (VPIs) with and without heart diseases. This was an observational cohort study that enrolled VPIs (born between 24+0 and 31+6 weeks) admitted to 79 tertiary neonatal intensive care units (NICU) in the Chinese Neonatal Network (CHNN) between 2019 and 2021. The exposure was CHD or isolated PDA, and VPIs with NEC were divided into three groups: complicated with CHD, with isolated PDA, and without heart diseases. The primary outcomes were NEC-related adverse outcomes (death or extrauterine growth restriction (EUGR)). Logistic regression models were used to adjust potential confounders and calculate the odds ratios (ORs) and 95% confidential intervals (CIs) for each outcome. A total of 1335 VPIs with NEC were enrolled in this study, including 65 VPIs with CHD and 406 VPIs with isolated PDA. The VPIs with heart diseases had smaller gestational ages and lower body weights at birth, more antenatal steroids use, and requiring inotrope prior to the onset of NEC. While suffering from NEC, there was no significant increased risks in NEC-related death in VPIs with either CHD (adjusted OR [aOR]: 1.10; 95% CI: 0.41-2.50) or isolated PDA (aOR: 1.25; 95% CI 0.82-1.87), and increased risks in EUGR were identified in either survival VPIs with CHD (aOR: 2.35; 95% CI: 1.31-4.20) or isolated PDA (aOR: 1.53; 95% CI: 1.16-2.01) in survivors. The composite outcome (death or EUGR) was also more often observed in VPIs with either CHD (aOR: 2.07; 95% confidence interval [CI]: 1.20-3.60) or isolated PDA (aOR: 1.51; 95% CI: 1.17-1.94) than that without heart diseases. VPIs with either CHD or isolated PDA were associated with significantly prolonged duration of fasting, extended time to achieve full enteral feeding, and longer ventilation duration and hospitalization duration. Similar characteristics were also seen in VPIs with isolated PDA, with the exception that VPIs with CHD are more likely to undergo surgical intervention and maintain a prolonged fast after NEC. Conclusion: In VPIs with NEC, CHD and isolated PDA are associated with an increased risk in worse outcomes. We recommend that VPIs with cardiac NEC be managed with aggressive treatment and nutrition strategies to prevent EUGR. What is Known: • CHD and PDA are risk factors for NEC in infants, which can lead to adverse outcomes such as death and EUGR. • NEC in infants with heart disease differs clinically from that in infants without heart disease and should be recognized as a separate disease process. What is New: • CHD and isolated PDA are associated with increased risks of EUGR in VPIs with NEC. • Risk factors associated with VPIs with cardiac NEC suggested these patients should be managed with aggressive treatment and nutrition strategies to adverse outcomes.

Nehab SRG, Villela LD, Abranches AD, Gomes Junior SCS, Soares FVM, Moreira MEL. Association between preterm infant body composition in the first 3 months of life and preschool age: a cohort study. Eur J Pediatr 2024; 183:3369-3375. [PMID: 38753218 DOI: 10.1007/s00431-024-05603-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 05/04/2024] [Accepted: 05/07/2024] [Indexed: 07/23/2024]
Abstract
Compared with full-term infants, preterm infants have fat-free mass deficit in the first months of life, which increases the risk of metabolic diseases in the future. In this cohort of children born under 32-week gestational age or less than 1500 g, we aimed to evaluate the associations of body composition at term equivalent age and in the first 3 months of life with fat-free mass and fat mass percentage at 4 to 7 years of life. Body composition assessments by air displacement plethysmography and anthropometry were performed at term, at 3 months of corrected age, and at 4 to 7 years of age. Multiple linear regression analysis was used to observe the associations between body composition at these ages. At term, fat mass percentage showed a negative association and fat-free mass a positive association with fat-free mass at 4 to 7 years. The fat-free mass at 3 months and the gain in fat-free mass between term and 3 months showed positive associations with fat-free mass at 4 to 7 years. Conclusion: Body composition at preschool age is associated with fat-free mass in the first 3 months of life, a sensitive period for the risk of metabolic diseases. What is Known: • Preterm infants have a deficit in fat-free mass and high adiposity at term equivalent age compared to full-term infants. • Fat-free mass reflects metabolic capacity throughout life and therefore is considered a protective factor against the risk of metabolic syndrome. What is New: •Fat-free mass gain in the first 3 months of corrected age is associated with fat-free mass at preschool and school ages. •The first 3 months of life is a sensitive period to the risk of metabolic diseases.

[PMID: 39005106 DOI: 10.1542/peds.2024-065905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 04/23/2024] [Accepted: 04/23/2024] [Indexed: 07/16/2024] Open
Abstract
BACKGROUND AND OBJECTIVE The optimal patent ductus arteriosus (PDA) closure method in very low birth weight (VLBW) infants is uncertain. In 2019, the first transcatheter occlusion device was approved in the United States for infants ≥700 g. We described survival and short-term outcomes among VLBW infants who underwent transcatheter or surgical PDA closure (2018-2022). METHODS Vermont Oxford Network members submitted data on infants born from 401 to 1500 g or 22 to 29 weeks' gestational age. Adjusted risk ratios (aRR) for survival, length of stay (LOS), prematurity complications, and discharge support were used to compare transcatheter versus surgical closure. Subgroup analyses were conducted for infants with birth weight ≥700 g and born in 2020-2022. RESULTS Overall, 6410 of 216 267 infants at 726 hospitals received invasive PDA treatment. Transcatheter closure increased from 29.8% in 2018 to 71.7% in 2022. VLBW infants undergoing transcatheter closure had higher survival (adjusted rate ratio [aRR] 1.03; 1.02-1.04) with similar LOS (aRR 1.00; 0.97-1.03), neonatal complications (aRR 1.00; 0.98-1.01), and receipt of discharge support (aRR 0.94; 0.89-1.01). In subgroup analyses, survival (aRR 1.02; 1.00-1.04) and discharge support (aRR 0.90; 0.81-1.01) were similar between groups, whereas selected neonatal complications (aRR 0.95; 0.93-0.98) and LOS (aRR 0.95; 0.90-0.99) were lower after transcatheter closure. CONCLUSIONS Transcatheter PDA closure in VLBW infants was increasingly used after 2018. Selected short-term outcomes for infants receiving transcatheter closure may be more favorable, compared with surgical, and warrants further clinical investigation.

Abstract
BACKGROUND Regional fat distribution may be a marker of metabolic health and brain growth in preterm infants. Point of care ultrasound has been used to assess regional fat in term infants but has not been used widely in preterm infants. OBJECTIVE To longitudinally quantify changes in body composition metrics using bedside ultrasound in very preterm infants. STUDY DESIGN Very preterm infants (N = 69) were enrolled after birth and body composition assessments were done through 36 completed weeks' postmenstrual age (PMA). Linear mixed effects regression was used to model change in body composition assessments over time. RESULTS There was an average increase across PMA for each body composition outcome. Biceps ultrasound subcutaneous fat (SQF) thickness increased by 0.11 mm (95% CI: 0.09, 0.13) each postmenstrual week. Triceps, subscapular, and abdominal ultrasound SQF remained constant through 28 weeks' PMA, then increased each week through 36 completed weeks' PMA. The inter-rater and intra-rater intraclass correlation coefficients for the ultrasound SQF measures ranged from 85.8 to 99.9. CONCLUSION Use of ultrasound as a novel method to assess regional fat distribution in very preterm infants is feasible and reliable. IMPACT Regional fat distribution may be a marker of metabolic health and brain growth in preterm infants. Gold standard body composition assessments may not be feasible in medically fragile very preterm infants. This study assesses longitudinally changes in regional adiposity development using bedside ultrasound techniques in a multicenter cohort of very preterm infants. Results of this study show that bedside ultrasound as a novel method to assess regional subcutaneous fat distribution and development in very preterm infants is both feasible and reliable.

Abstract
OBJECTIVE Racism leads to disparities in health outcomes. Our objective was to determine if black race was independently associated with differences in fat accretion at discharge in a large cohort of very preterm infants (32 weeks of gestation or less). METHODS De-identified demographic, anthropometric and body composition data were collected from seven neonatal units around the United States. Weight, length, and head circumference z-scores at birth and at the time of body composition assessment or hospital discharge were calculated. RESULTS The median gestational age and birthweight for this cohort (n = 888) were 29 weeks [IQR, 27-30] and 1167 g [SD, 354], respectively. The study population included 53% black preterm infants. Birthweight was lower in black preterm infants compared with white infants (1112 ± 334 g vs. 1228 ± 366 g; p < 0.0001). After adjusting for birthweight, gestational age, and birthweight-for-age z-score, black preterm infants had more weight gain (adjusted mean difference: 0.5 g/kg/day; p = 0.03) but not higher BF% z-scores at hospital discharge (adjusted mean: 1.2 vs. 1.3; p = 0.14) than white infants. CONCLUSIONS After adjusting for covariates, black race was associated with higher weight gain velocity but not higher BF% z-scores. IMPACT This study presents findings from a large-scale multicenter cohort. Racial differences were observed in birth weight and the rate of weight gain; however, these differences were not associated with dissimilarities in body composition outcomes. Understanding nutrition and growth outcomes across racial groups is necessary to combat racial disparities in the neonatal intensive care unit (NICU).

Abstract
OBJECTIVES To examine trends over time in diet and size of very preterm infants, and associations of diet with size at hospital discharge/transfer. METHODS The authors studied 4062 surviving very preterm infants born < 32 weeks' gestational age and < 1500 g between January 2012 and December 2020 from 12 Brazilian Neonatal Intensive Care Units. Diet type at discharge/transfer was classified as exclusive human milk, exclusive formula, or mixed. Outcomes were weight and head circumference at hospital discharge and the change in each from birth to discharge. The authors used linear regression to estimate adjusted associations of diet type with infant size, overall, and stratified by fetal growth category (small vs. appropriate for gestational age). The authors also examined trends in diet and infant size at discharge over the years. RESULTS Infants' mean gestational age at birth was 29.3 weeks, and the mean birth weight was 1136 g. Diet at discharge/transfer was exclusive human milk for 22 %, mixed for 62 %, and exclusive formula for 16 %. Infant size in weight and head circumference were substantially below the growth chart reference for all diets. Infants fed human milk and mixed diets were lighter and had smaller heads at discharge/transfer than infants fed formula only (weight z: -2.0, -1.8, and -1.5; head z: -1.3, -1.2 and -1.1 for exclusive human milk, mixed and exclusive formula respectively). CONCLUSION Results suggest high human milk use but gaps in nutrient delivery among hospitalized Brazilian very preterm infants, with little evidence of improvement over time.

Abstract
OBJECTIVES To compare clinical outcomes for infants with neonatal opioid withdrawal syndrome (NOWS) treated with buprenorphine or morphine. STUDY DESIGN Retrospective study of infants born ≥35 weeks' gestation and admitted to the NICU for NOWS treatment between 2011 and 2022. Length of treatment, length of stay in the hospital, and the need for secondary medications were compared between buprenorphine and morphine treated neonates. Multiple regression analysis was performed, adjusting for baseline differences and confounders. RESULTS 417 neonates were treated with morphine and 232 with buprenorphine. The buprenorphine group had shorter treatment days [-10.8 days; 95% CI: -8.08 to -13.53] and shorter hospital stay [-11.8 days; 95% CI: -8.83 to -14.78]. The buprenorphine group was no more likely to receive phenobarbital or clonidine (26% vs. 29%). CONCLUSION In this large single-center study, buprenorphine was associated with shorter lengths of treatment and hospital stay in the treatment of NOWS compared to morphine.

Abstract
The phenotype of human placental extravillous trophoblast (EVT) at the end of pregnancy reflects both first trimester differentiation from villous cytotrophoblast (CTB) and later gestational changes, including loss of proliferative and invasive capacity. Invasion abnormalities are central to two major placental pathologies, preeclampsia and placenta accreta spectrum, so characterization of the corresponding normal processes is crucial. In this report, our gene expression analysis, using purified human CTB and EVT cells, highlights an epithelial-mesenchymal transition (EMT) mechanism underlying CTB-EVT differentiation and provides a trophoblast-specific EMT signature. In parallel, DNA methylation profiling shows that CTB cells, already hypomethylated relative to non-trophoblast cell lineages, show further genome-wide hypomethylation in the transition to EVT. However, a small subgroup of genes undergoes gains of methylation (GOM) in their regulatory regions or gene bodies, associated with differential mRNA expression (DE). Prominent in this GOM-DE group are genes involved in the EMT, including multiple canonical EMT markers and the EMT-linked transcription factor RUNX1, for which we demonstrate a functional role in modulating the migratory and invasive capacities of JEG3 trophoblast cells. This analysis of DE associated with locus-specific GOM, together with functional studies of an important GOM-DE gene, highlights epigenetically regulated genes and pathways acting in human EVT differentiation and invasion, with implications for obstetric disorders in which these processes are dysregulated.

Abstract
BACKGROUND Antenatal corticosteroids decrease the incidence of severe intraventricular hemorrhage (grades 3, 4) in preterm infants. It is unclear whether their beneficial effects on intraventricular hemorrhage wane with time (as occurs in neonatal respiratory distress) and if repeat courses can restore this effect. Previous randomized controlled trials of betamethasone retreatment found no benefit on severe intraventricular hemorrhage rates. However, the trials may have included an insufficient number of infants at risk for intraventricular hemorrhage to be able to adequately address this question. Severe intraventricular hemorrhages occur almost exclusively in infants born at <28 weeks' gestation, whereas only 7% (0%-16%) of the retreatment trials' populations were <28 weeks' gestation. OBJECTIVE This study aimed to determine if the risk for severe intraventricular hemorrhage in infants delivered at <28 weeks' gestation increases when the betamethasone treatment-to-delivery interval increases beyond 9 days and to determine if betamethasone retreatment before delivery decreases the rate of hemorrhage. STUDY DESIGN This was an observational study that examined the incidence of intraventricular hemorrhage before (epoch 1) and after (epoch 2) a practice change that encouraged obstetricians to retreat pregnant women still at high risk for delivery before 28 weeks' gestation when >9 days elapsed from the first dose of betamethasone. Multivariable analyses with logistic regression using generalized estimating equation techniques were conducted to examine the rates of intraventricular hemorrhage among 410 infants <28 weeks' gestation who were either delivered between 1 to 9 days (n=290) after the first 2-dose betamethasone course or ≥10 days (and eligible for retreatment) after the first course (n=120). RESULTS After adjusting for potential confounding variables, infants who were delivered ≥10 days after a single betamethasone course had an increased risk for either severe intraventricular hemorrhage alone or the combined outcome severe intraventricular hemorrhage or death before 4 days (odds ratio, 2.8; 95% confidence interval, 1.2-6.6) when compared with infants who were delivered between 1 and 9 days after betamethasone. Among the 120 infants who were delivered ≥10 days after the first dose of betamethasone, 64 (53%) received a second or retreatment course of antenatal betamethasone. The severe intraventricular hemorrhage rate in infants whose mothers received a second or retreatment course of betamethasone was similar to the rate among infants who delivered within 1 to 9 days and significantly lower than among those who delivered ≥10 days without retreatment (odds ratio, 0.10; 95% confidence interval, 0.02-0.65). Following the change in guidelines, the rate of retreatment in infants who were delivered ≥10 days after the first betamethasone course (and before 28 weeks) increased from epoch 1 to epoch 2 (25% to 87%; P<.001) and the rate of severe intraventricular hemorrhage decreased from 22% to 0% (P<.001). In contrast, the rate of severe intraventricular hemorrhage among infants who were delivered 1 to 9 days after the initial betamethasone dose (who were not eligible for retreatment) did not change between epochs 1 and 2 (12% and 11%, respectively). CONCLUSION Although betamethasone's benefits on severe intraventricular hemorrhage appear to wane after the first dose, retreatment with a second course seems to restore its beneficial effects. Encouraging earlier retreatment of women at high risk for delivery before 28 weeks was associated with a lower rate of severe intraventricular hemorrhages among infants delivered at <28 weeks' gestation.

Multiple criteria and growth references have been proposed for extrauterine growth restriction (EUGR). We hypothesized that these may impact the diagnosis of EUGR. The objective was to evaluate the prevalence of EUGR with its different definitions and the concordance according to Fenton, Olsen, and INTERGROWTH-21st in very-low-birthweight (VLBW) infants. This is an observational, retrospective, and multicenter study including VLBW infants from the Spanish SEN1500 Network from 2011 to 2020. Patients with major congenital anomalies, embryopathies, and gestational age less than 24 weeks were excluded. EUGR prevalence was calculated at discharge with cross-sectional, longitudinal, "true" cross-sectional, and "true" longitudinal definitions. Concordance was assessed with Fleiss' kappa coefficient. 23582 VLBW infants from 77 NICUs were included. In total, 50.4% were men with a median of gestational age of 29 (4) weeks. The prevalence of EUGR (cross-sectional, longitudinal, and "true") was variable for weight, length, and head circumference. Overall, the prevalence was higher with Fenton and lower with Olsen (cross-sectional and "true" cross-sectional) and INTERGROWTH-21st (longitudinal and "true" longitudinal). Agreement among the charts by weight was good only for cross-sectional EUGR and moderate for longitudinal, "true" cross-sectional, and "true" longitudinal. Concordance was good or very good for EUGR by length and head circumference.Conclusions: The prevalence of EUGR with the most commonly used definitions was variable in the cohort. Agreement among growth charts was moderate for all the definitions of EUGR by weight except cross-sectional and good or very good for length and head circumference. The choice of reference chart can impact the establishment of the diagnosis of EUGR. What is known: • EUGR has been defined in the literature and daily practice considering weight, length and head circumference with multiple criteria (cross-sectional, longitudinal, and "true" definition) • Different growth charts have been used for EUGR diagnosis What is new: • Prevalence of EUGR is variable depending on the definition and growth chart used in our cohort of VLBW infants • For the most frequently EUGR criteria used, traditionally considering weight, concordance among Fenton, Olsen and INTERGROWTH-21st growth charts is only moderate for all the definitions of EUGR by weight except cross-sectional definition. Concordance among the charts is good or very good for the different criteria of EUGR by head circumference and length.

Abstract
AIM The aim of this study is to evaluate an early discharge programme with video consultations for preterm infants. METHODS A homecare programme for preterm infants was developed. Prospective data on readmissions, length of stay, growth, breastfeeding rates, and parent self-reports about satisfaction were collected from April 2021 to August 2023. Additionally, retrospective data were collected from the Norwegian Neonatal Network Central Database from 2020. RESULTS Preterm infants, 72 and parents, 128 were included. The infants were discharged from the hospital at a median of 35 + 6 (34 + 0-42 + 4) weeks postmenstrual age. The median length of stay in the program was 18 days (3-37). There were four readmissions. The Z-score of infant weight slightly increased during the follow up, with a mean of 0.16. By discharge, 75% of the infants were exclusively breastfed. Growth and breastfeeding rates were in line with retrospective data (85 infants). The response rate of the parents to the survey was 61 (52%). Overall, the parents (n = 54) were highly satisfied (96%). The video consultations contributed to ensuring parents to feel safe in caring for their infant at home. CONCLUSION Follow up by video consultations is a viable healthcare service for preterm infants, the infants' growth is sufficient, breastfeeding rates are maintained, and parents feel safe and satisfied.

Abstract
PURPOSE Obesity surgery and polycystic ovary syndrome (PCOS) are both associated with increased risk of intrauterine growth restriction. We investigated whether offspring of mothers with PCOS who underwent obesity surgery had an increased risk of deviating birth anthropometrics compared to offspring of mothers without PCOS. METHODS In this observational study, data from two study databases (BAROBS and PregMet2) were supplemented with data from patient's records from secondary and tertiary hospitals. In total, 162 offspring born to mothers with PCOS (n = 48) and without PCOS (n = 114) were included. Forty-nine offspring were born prior to, and 113 after obesity surgery. RESULTS Mean ± SD birthweight (BW), birth length (BL), and head circumference (HC) before and after surgery for offspring born to mothers with PCOS were 3987 ± 495 g vs 3396 ± 526 g (P = 0.001), 52.2 ± 1.6 cm vs 50.1 ± 2.2 cm (P = 0.010), and 36.3 ± 1.97 cm vs 35.3 ± 1.66 cm (P = 0.183), respectively. In the non-PCOS group BW, BL and HC before and after were 3859 ± 603 g vs 3490 ± 538 g (P = 0.001), 51.3 ± 2.0 cm vs 49.9 ± 2.5 cm (P = 0.013), and 36.4 ± 2.0 cm vs 35.3 ± 1.8 cm (P = 0.016), respectively. Post-surgery, we found no difference in z-score BW, (∆-0.08, P = 0.677), BL (∆0.21, P = 0.184), and HC (∆0.14, P = 0.476) between children of PCOS and non-PCOS mothers. COMCLUSION Babies born after obesity surgery were smaller and shorter in both the PCOS and non-PCOS group. Post-surgery anthropometrics were similar in babies born to mothers with and without PCOS.

JAMA Netw Open 2024; 7:e2419268. [PMID: 38976271 PMCID: PMC11231799 DOI: 10.1001/jamanetworkopen.2024.19268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 04/18/2024] [Indexed: 07/09/2024] Open
Abstract
Importance A nonadjuvanted bivalent respiratory syncytial virus (RSV) prefusion F (RSVpreF [Pfizer]) protein subunit vaccine was newly approved and recommended for pregnant individuals at 32 0/7 to 36 6/7 weeks' gestation during the 2023 to 2024 RSV season; however, clinical vaccine data are lacking. Objective To evaluate the association between prenatal RSV vaccination status and perinatal outcomes among patients who delivered during the vaccination season. Design, Setting, and Participants This retrospective observational cohort study was conducted at 2 New York City hospitals within 1 health care system among patients who gave birth to singleton gestations at 32 weeks' gestation or later from September 22, 2023, to January 31, 2024. Exposure Prenatal RSV vaccination with the RSVpreF vaccine captured from the health system's electronic health records. Main Outcome and Measures The primary outcome is preterm birth (PTB), defined as less than 37 weeks' gestation. Secondary outcomes included hypertensive disorders of pregnancy (HDP), stillbirth, small-for-gestational age birth weight, neonatal intensive care unit (NICU) admission, neonatal respiratory distress with NICU admission, neonatal jaundice or hyperbilirubinemia, neonatal hypoglycemia, and neonatal sepsis. Logistic regression models were used to estimate odds ratios (ORs), and multivariable logistic regression models and time-dependent covariate Cox regression models were performed. Results Of 2973 pregnant individuals (median [IQR] age, 34.9 [32.4-37.7] years), 1026 (34.5%) received prenatal RSVpreF vaccination. Fifteen patients inappropriately received the vaccine at 37 weeks' gestation or later and were included in the nonvaccinated group. During the study period, 60 patients who had evidence of prenatal vaccination (5.9%) experienced PTB vs 131 of those who did not (6.7%). Prenatal vaccination was not associated with an increased risk for PTB after adjusting for potential confounders (adjusted OR, 0.87; 95% CI, 0.62-1.20) and addressing immortal time bias (hazard ratio [HR], 0.93; 95% CI, 0.64-1.34). There were no significant differences in pregnancy and neonatal outcomes based on vaccination status in the logistic regression models, but an increased risk of HDP in the time-dependent model was seen (HR, 1.43; 95% CI, 1.16-1.77). Conclusions and Relevance In this cohort study of pregnant individuals who delivered at 32 weeks' gestation or later, the RSVpreF vaccine was not associated with an increased risk of PTB and perinatal outcomes. These data support the safety of prenatal RSVpreF vaccination, but further investigation into the risk of HDP is warranted.

Lactoferrin intake from maternal milk during the neonatal hospitalization and early brain development among preterm infants. Pediatr Res 2024; 96:159-164. [PMID: 38191822 DOI: 10.1038/s41390-023-03002-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 12/11/2023] [Accepted: 12/13/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND Lactoferrin is an immuno-modulatory nutrient in human milk that may be neuroprotective. METHODS In 36 infants born <32 weeks' gestation, we sampled human milk at 14 and 28 days of chronologic age and measured lactoferrin by electrochemiluminescence multiplex immunoassay. Using 3T quantitative brain magnetic resonance imaging scans obtained at term equivalent, we estimated total and regional brain volumes. We compared outcomes between infants exposed to low (bottom tertile, range 0.06-0.13 mg/mL) vs. high (top tertile, range 0.22-0.35 mg/mL) lactoferrin using median regression in models adjusted for gestational age, birth weight z-score, sex, and postmenstrual age. RESULTS Compared to infants exposed to low lactoferrin, infants exposed to high lactoferrin had 43.9 cc (95% CI: 7.6, 80.4) larger total brain volume, 48.3 cc (95% CI: 12.1, 84.6) larger cortical gray matter, and 3.8 cc (95% CI: 0.7, 7.0) larger deep gray matter volume at term equivalent age. Other regional brain volumes were not statistically different between groups. CONCLUSION Higher lactoferrin exposure during the neonatal hospitalization was associated with larger total brain and gray matter volumes, suggesting that lactoferrin may have potential as a dietary supplement to enhance brain growth in the neonatal intensive care unit setting. IMPACT This study suggests that lactoferrin, a whey protein found in human milk, may be beneficial for preterm infant brain development, and therefore has potential as a dietary supplement in the neonatal intensive care unit setting.

Abstract
BACKGROUND Infants born moderate-to-late preterm (i.e., 32 wk-35 wk 6 d gestation) are, analogous to those born very preterm, at risk of later obesity, hypertension, and diabetes. Appropriate early life nutrition is key for ensuring optimal growth and body composition, thereby mitigating potential cardiometabolic risks. OBJECTIVES We aimed to compare growth and body composition between infants born moderate-to-late preterm fed isocaloric but protein- and mineral-enriched postdischarge formula (PDF) or standard term formula (STF) until 6 mo corrected age (CA; i.e., after term equivalent age [TEA]). METHODS After enrollment (≤7 d postpartum), infants received PDF if (fortified) mother's own milk (MOM) was insufficient. At TEA, those receiving >25% of intake as formula were randomized to either continue the same PDF (n = 47) or switch to STF (n = 50); those receiving ≥75% of intake as MOM (n = 60) served as references. At TEA and 6 mo CA, we assessed anthropometry and body composition using both dual-energy x-ray absorptiometry (DXA) and air displacement plethysmography (ADP). RESULTS Feeding groups had similar gestational age (median [25th percentile;75th percentile]: 34.3 [33.5; 35.1] wk), birthweight (mean ± standard deviation [SD]: 2175 ± 412 g), anthropometry, and body composition at TEA. At 6 mo CA, infants fed PDF had slightly, but significantly, greater length (67.6 ± 2.5 and 66.9 ± 2.6 cm, P < 0.05) and larger head circumference (43.9 ± 1.3 and 43.4 ± 1.5 cm, P < 0.05) compared to infants fed STF. Also, infants fed PDF had higher lean mass (LM) and bone mineral content estimated by DXA (4772 ± 675 and 4502 ± 741 g; 140 ± 20 and 131 ± 23 g, respectively; P < 0.05). ADP estimates, however, were not statistically different between feeding groups. CONCLUSIONS Infants born moderate-to-late preterm demonstrated modest increases in length, head circumference, LM, and bone mineral content when fed PDF compared to STF for 6 mo after TEA. This trial was registered at the International Clinical Trial Registry Platform as NTR5117 and NTR NL4979.

Abstract
OBJECTIVE Determine the association between severe hypertensive disease of pregnancy (HDP) with moderate-severe bronchopulmonary dysplasia (BPD) in preterm infants (< 31 weeks' gestation). STUDY DESIGN Preterm birth cohort study of 693 mother-infant dyads. Severe HDP was defined as severe preeclampsia, HELLP syndrome or eclampsia. The outcome was moderate-severe BPD classified at 36 weeks corrected gestational age, per the NICHD Consensus statement. RESULTS 225 (32%) mothers developed severe HDP and 234 (34%) infants had moderate-severe BPD. There was an interaction between severe HDP and gestational age (p = 0.03). Infants born at < 25 weeks gestation to mothers with HDP had increased odds for moderate-severe BPD compared to infants of normotensive mothers delivering at the same gestational age. Infants born > 28 weeks to mothers with severe HDP had decreased odds for the outcome, though not statistically significant. CONCLUSIONS Severe HDP has a differential effect on the development of moderate-severe BPD based on gestational age.

Abstract
PURPOSE To investigate the association of parity with a range of neonatal anthropometric measurements in a cohort of uncomplicated term singleton pregnancies. METHODS Retrospective cohort study of patients with a singleton term birth at a single tertiary center (2014-2020) was carried out. The primary exposure was parity. The following neonatal anthropometric measures were considered: birthweight, head circumference, length, ponderal index, and neonatal body mass index (BMI). RESULTS A total of 8134 patients met the study criteria, 1949 (24.0%) of whom were nulliparous. Compared with multiparous patients, infants of nulliparous patients had a lower mean percentile for birthweight (43.1 ± 26.4 vs. 48.3 ± 26.8 percentile, p < 0.001), head circumference (44.3 ± 26.4 vs. 48.1 ± 25.5 percentile, p < 0.001), length (52.6 ± 25.1 vs. 55.5 ± 24.6 percentile, p < 0.001), ponderal index (34.4 ± 24.0 vs. 37.6 ± 24.2 percentile, p < 0.001), and BMI (39.1 ± 27.1 vs. 43.9 ± 27.3 percentile, p < 0.001). In addition, infants of nulliparous patients had higher odds of having a small (< 10th percentile for gestational age) birthweight (aOR 1.32 [95% CI 1.12-1.56]), head circumference (aOR 1.54 [95% CI 1.29-1.84]), length (aOR 1.50 [95% CI 1.16-1.94]), ponderal index (aOR 1.30 [95% CI 1.12-1.51]), and body mass index (aOR 1.42 [95% CI 1.22-1.65]). Most neonatal anthropometric measures increased with parity until a parity of 2, where it seemed to reach a plateau. CONCLUSION Parity has an independent impact on a wide range of neonatal anthropometric measures, suggesting that parity is associated with both fetal skeletal growth and body composition. In addition, the association of parity with fetal growth does not follow a continuous relationship but instead reaches a plateau after the second pregnancy.

Am J Obstet Gynecol 2024; 231:122.e1-122.e9. [PMID: 38527606 PMCID: PMC11194156 DOI: 10.1016/j.ajog.2024.03.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 03/19/2024] [Accepted: 03/21/2024] [Indexed: 03/27/2024]
Abstract
BACKGROUND Continuous glucose monitoring has facilitated the evaluation of dynamic changes in glucose throughout the day and their effect on fetal growth abnormalities in pregnancy. However, studies of multiple continuous glucose monitoring metrics combined and their association with other adverse pregnancy outcomes are limited. OBJECTIVE This study aimed to (1) use machine learning techniques to identify discrete glucose profiles based on weekly continuous glucose monitoring metrics in pregnant individuals with pregestational diabetes mellitus and (2) investigate their association with adverse pregnancy outcomes. STUDY DESIGN This study analyzed data from a retrospective cohort study of pregnant patients with type 1 or 2 diabetes mellitus who used Dexcom G6 continuous glucose monitoring and delivered a nonanomalous, singleton pregnancy at a tertiary center between 2019 and 2023. Continuous glucose monitoring data were collapsed into 39 weekly glycemic measures related to centrality, spread, excursions, and circadian cycle patterns. Principal component analysis and k-means clustering were used to identify 4 discrete groups, and patients were assigned to the group that best represented their continuous glucose monitoring patterns during pregnancy. Finally, the association between glucose profile groups and outcomes (preterm birth, cesarean delivery, preeclampsia, large-for-gestational-age neonate, neonatal hypoglycemia, and neonatal intensive care unit admission) was estimated using multivariate logistic regression adjusted for diabetes mellitus type, maternal age, insurance, continuous glucose monitoring use before pregnancy, and parity. RESULTS Of 177 included patients, 90 (50.8%) had type 1 diabetes mellitus, and 85 (48.3%) had type 2 diabetes mellitus. This study identified 4 glucose profiles: (1) well controlled; (2) suboptimally controlled with high variability, fasting hypoglycemia, and daytime hyperglycemia; (3) suboptimally controlled with minimal circadian variation; and (4) poorly controlled with peak hyperglycemia overnight. Compared with the well-controlled profile, the suboptimally controlled profile with high variability had higher odds of a large-for-gestational-age neonate (adjusted odds ratio, 3.34; 95% confidence interval, 1.15-9.89). The suboptimally controlled with minimal circadian variation profile had higher odds of preterm birth (adjusted odds ratio, 2.59; 95% confidence interval, 1.10-6.24), cesarean delivery (adjusted odds ratio, 2.76; 95% confidence interval, 1.09-7.46), and neonatal intensive care unit admission (adjusted odds ratio, 4.08; 95% confidence interval, 1.58-11.40). The poorly controlled profile with peak hyperglycemia overnight had higher odds of preeclampsia (adjusted odds ratio, 2.54; 95% confidence interval, 1.02-6.52), large-for-gestational-age neonate (adjusted odds ratio, 3.72; 95% confidence interval, 1.37-10.4), neonatal hypoglycemia (adjusted odds ratio, 3.53; 95% confidence interval, 1.37-9.71), and neonatal intensive care unit admission (adjusted odds ratio, 3.15; 95% confidence interval, 1.20-9.09). CONCLUSION Discrete glucose profiles of pregnant individuals with pregestational diabetes mellitus were identified through joint consideration of multiple continuous glucose monitoring metrics. Prolonged exposure to maternal hyperglycemia may be associated with a higher risk of adverse pregnancy outcomes than suboptimal glycemic control characterized by high glucose variability and intermittent hyperglycemia.

Role of parental smoking and environmental tobacco smoke exposure in childhood cancer: A study using hair cotinine analysis and questionnaires. Pediatr Blood Cancer 2024; 71:e31007. [PMID: 38654470 DOI: 10.1002/pbc.31007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 03/18/2024] [Accepted: 03/27/2024] [Indexed: 04/26/2024]
Abstract
OBJECTIVES In the etiology of childhood cancers, many genetic and environmental factors play a role. One of these factors could be cigarette smoking, and the main source of tobacco smoke exposure of children is parental smoking. However, establishing a causal relationship between parental smoking and childhood cancers has proven challenging due to difficulties in accurately detecting tobacco smoke exposure METHODS: To address this issue, we used hair cotinine analysis and a questionnaire to get information about tobacco smoke exposures of pediatric cancer patients and healthy children. A total of 104 pediatric cancer patients and 99 healthy children participated in our study. Parental smoking behaviors (pre-conceptional, during pregnancy, and current smoking) and environmental tobacco smoke (ETS) exposures of children are compared. RESULTS We have found no differences between two groups by means of maternal smoking behaviors. However, the rates of paternal pre-conceptional smoking and smoking during pregnancy were significantly low in cancer patients (p < .05). These data suggest that social desirability bias among fathers of cancer patients may have contributed to this discrepancy. According to questionnaire, cancer patients had significantly lower ETS exposures than healthy children (p < .05). However, ETS exposure assessment through cotinine analysis demonstrated that cancer patients had higher exposure to ETS compared to healthy children (p < .001). CONCLUSION Our findings provide evidence supporting the potential role of smoking as a risk factor for childhood cancers. This study also revealed that questionnaires could cause biases. We suggest that cotinine analysis along with validated questionnaires can be used to prevent biases in studies of tobacco smoke in the etiology of childhood cancers.

Abstract
OBJECTIVE To compare survival without BPD among extremely preterm infants (EPI) who received prophylactic early low-dose hydrocortisone (PEH) with those who did not (non-PEH). STUDY DESIGN This single-center retrospective study compared risk-adjusted rates of survival without BPD, BPD, bowel perforation, and late-onset sepsis among infants (22-27 weeks' gestation at birth) who received PEH (n = 82) and who did not (n = 205). RESULTS Infants in the PEH group were of lower gestational age, lower birthweight, and higher day-1 risk of death/BPD. After adjusting for risk of death/BPD, PEH-treated infants demonstrated increased survival without BPD (aOR 2.04, 95%CI 1.1-3.7), and lower BPD rates (aOR 0.46, 95%CI 0.25-0.87). Importantly, bowel perforation or sepsis rate were similar among both groups. CONCLUSION After risk adjustment, PEH-treated infants demonstrated improved survival without BPD and did not increase rates of bowel perforation or sepsis. In our cohort of infants, PEH was safe and effective among the sickest preterm neonates.

Hospital-Onset Bacteremia Among Neonatal Intensive Care Unit Patients. JAMA Pediatr 2024:2819783. [PMID: 38913368 PMCID: PMC11197452 DOI: 10.1001/jamapediatrics.2024.1840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 04/03/2024] [Indexed: 06/25/2024]
Abstract
Importance The Centers for Disease Control and Prevention plans to introduce hospital-onset bacteremia (HOB) as a health care-associated infection measure. The epidemiology and clinical characteristics of HOB among infants admitted to the neonatal intensive care unit (NICU) are unknown. Objective To estimate the rate of HOB among infants admitted to the NICU, measure the association of HOB risk with birth weight group and postnatal age, and estimate HOB-attributable mortality. Design, Setting, and Participants This retrospective multicenter cohort study and emulated trial from 2016 to 2021 included a convenience sample of 322 NICUs in the United States. Participants were infants admitted to participating NICUs for 4 or more days. Exposures The primary exposures were birth weight and postnatal age. Additional exposures included small for gestational age and central line presence. Main Outcomes and Measures The primary study outcomes were HOB and HOB-attributable mortality. Results Of 451 443 included infants, 250 763 (55.6%) were male, 200 680 (44.4%) were female, and 62 091 (13.8%) were born 1500 g or less. Of 9015 HOB events that occurred among 8356 infants (2%) during 8 163 432 days at risk (unadjusted incidence rate, 1.1 per 1000 patient-days; 95% CI, 1.0-1.2), 4888 HOB events (54.2%) occurred in the absence of a central line. Within the first 2 weeks after birth, the HOB rate was 14.2 per 1000 patient-days (95% CI, 12.6-16.1) among infants born 750 g or less, to 0.4 events per 1000 patient-days among infants born more than 2500 g (95% CI, 0.4-0.5). Among infants born 750 g or less, the relative HOB risk decreased by 90% after day 42 compared with days 4 to 14 (incidence rate ratio [IRR], 0.10; 95% CI, 0.1-0.1). Conversely, among infants born more than 2500 g, the relative HOB risk increased by 50% after day 42 compared with days 4 to 14 (IRR, 1.5, 95% CI, 1.2-1.9). Compared with otherwise similar infants without HOB, infants with HOB had an absolute difference in attributable mortality of 5.5% (95% CI, 4.7-6.3). Conclusions and Relevance This study found that HOB events in the NICU are associated with increased mortality. Birth weight is an important risk factor for HOB; however, the relative rate of HOB decreases over postnatal age among low-birth-weight infants and increases among infants born more than 2500 g. Identifying strategies to prevent HOB and programs to decrease HOB risk are urgently needed to reduce infant mortality.

PDA management strategies and pulmonary hypertension in extreme preterm infants with bronchopulmonary dysplasia. Pediatr Res 2024:10.1038/s41390-024-03321-1. [PMID: 38898108 DOI: 10.1038/s41390-024-03321-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/11/2024] [Accepted: 05/15/2024] [Indexed: 06/21/2024]
Abstract
BACKGROUND Premature infants are at risk for developing pulmonary hypertension (PH) in the context of bronchopulmonary dysplasia (BPD). Studies suggest a potential link between prolonged patent ductus arteriosus (PDA) exposure and BPD-PH, though management strategies remain controversial. METHODS Retrospective echocardiographic evaluation of newborns <29 weeks gestational age with BPD at two distinct centers. Primary objective was to evaluate the relationship between center-specific PDA management strategies (interventional or conservative) and the prevalence of BPD-PH. BPD was defined as oxygen or respiratory support at 36 weeks post-menstrual age (PMA). The presence of PH was defined as either an estimated sPAP of ≥40 mmHg or sEI ≥1.3. Center A has a conservative PDA policy. Center B has a targeted interventional policy. RESULTS PH rates were similar between sites (21% vs 17%), while rates of PDA treatment was different (7% vs 81). Adjusted models did not demonstrate an association for center or PDA treatment exposure for PH and EI, although infants from Center A had echocardiography evidence of higher systolic eccentricity index (EI; 1.12 ± 0.19 vs 1.06 ± 0.15, p = 0.04). Markers of RV function (TAPSE and RV-FAC) were similar between groups. CONCLUSION In preterm infants <29 weeks with BPD, conservative PDA treatment policy was not associated with higher rate of pulmonary hypertension diagnosis. IMPACT The association between PDA-management approaches and the occurrence of BPD-associated pulmonary vascular disease in premature infants has sparsely been described. We found that a conservative policy, regarding the PDA, was not associated with an increase in pulmonary hypertension diagnosis. We identified that, in patients with BPD, echocardiographic metrics of LV performance were lower.

Abstract
OBJECTIVES To determine the dose-dependent associations between antenatal corticosteroids (ANS) exposure and the rates of major morbidities, and the early weight loss percentage (EWLP) in hospital among extremely preterm infants (EPI) or extremely low birthweight infants (ELBWI). METHODS A multicentre, retrospective cohort study of EPI or ELBWI born between 2017 and 2018 was conducted. Infants were classified into no ANS, partial ANS and complete ANS exposure group; three subgroups were generated by gestational age and birth weight. Multiple logistic regression and multiple linear regression were performed. RESULTS There were 725 infants included from 32 centres. Among no ANS, partial ANS and complete ANS exposure, there were significant differences in the proportions of bronchopulmonary dysplasia (BPD) (24.5%, 25.4% and 16.1%), necrotising enterocolitis (NEC) (6.7%, 2.0% and 2.0%) and death (29.6%, 18.5% and 13.5%), and insignificant differences in the proportions of intraventricular haemorrhage (IVH) (12.5%, 13.2% and 12.2%), and extrauterine growth restriction (EUGR) (50.0%, 56.6% and 59.5%). In the logistic regression, compared with no ANS exposure, complete ANS reduced the risk of BPD (OR 0.58, 95% CI 0.37 to 0.91), NEC (OR 0.21, 95% CI 0.08 to 0.57) and death (OR 0.36, 95% CI 0.23 to 0.56), and partial ANS reduced the risk of NEC (OR 0.23, 95% CI 0.07 to 0.72) and death (OR 0.54, 95% CI 0.34 to 0.87). Compared with partial ANS exposure, complete ANS decreased the risk of BPD (OR 0.58, 95% CI 0.37 to 0.91). There were insignificant associations between ANS exposure and IVH, EUGR. In the multiple linear regression, partial and complete ANS exposure increased EWLP only in the ≥28 weeks (w) and <1000 g subgroup (p<0.05). CONCLUSIONS Different doses of ANS (dexamethasone) exposure were protectively associated with BPD, NEC, death in hospital, but not EUGR at discharge among EPI or ELBWI. Beneficial dose-dependent associations between ANS (dexamethasone) exposure and BPD existed. ANS exposure increased EWLP only in the ≥28 w and<1000 g subgroup. ANS administration, especially complete ANS, is encouraged before preterm birth. TRIAL REGISTRATION NUMBER NCT06082414.

Abstract
OBJECTIVES To investigate the risk factors for bronchopulmonary dysplasia (BPD) in twin preterm infants with a gestational age of <34 weeks, and to provide a basis for early identification of BPD in twin preterm infants in clinical practice. METHODS A retrospective analysis was performed for the twin preterm infants with a gestational age of <34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020. According to their conditions, they were divided into group A (both twins had BPD), group B (only one twin had BPD), and group C (neither twin had BPD). The risk factors for BPD in twin preterm infants were analyzed. Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins. RESULTS A total of 904 pairs of twins with a gestational age of <34 weeks were included in this study. The multivariate logistic regression analysis showed that compared with group C, birth weight discordance of >25% between the twins was an independent risk factor for BPD in one of the twins (OR=3.370, 95%CI: 1.500-7.568, P<0.05), and high gestational age at birth was a protective factor against BPD (P<0.05). The conditional logistic regression analysis of group B showed that small-for-gestational-age (SGA) birth was an independent risk factor for BPD in individual twins (OR=5.017, 95%CI: 1.040-24.190, P<0.05). CONCLUSIONS The development of BPD in twin preterm infants is associated with gestational age, birth weight discordance between the twins, and SGA birth.

Pediatr Res 2024:10.1038/s41390-024-03307-z. [PMID: 38858503 DOI: 10.1038/s41390-024-03307-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 04/22/2024] [Accepted: 05/22/2024] [Indexed: 06/12/2024]
Abstract
BACKGROUND FICare model has been evaluated mostly on the stable preterm infant.We have scaled the model to two implementation levels(basic/advanced),making it suitable for all high-risk neonates.We report on the short- and mid-term outcomes of infants enrolled in a pilot on FICare implementation at our NICU. METHODS During 52 months study period,families were invited to join the program if their newborns' admission required neonatal specialized care for at least 3 weeks,and trained according to the program's curricula.Following a rigorous sequential admission order,each case(FICare group:134 < 34 weeks;52 term newborns)was matched by a contemporary control(CC:134 < 34 weeks;52 term newborns)and 2 historical controls born within the 3 years prior to FICare site implementation(HC:268 < 34 weeks;104 term newborns),cared as usual RESULTS: FICare intervention started by the end of first week of postnatal life.Rates of breastfeeding during admission and at discharge,and direct breastfeeding upon discharge were higher in FICare compared to CC and HC.Duration of intermediate care hospitalization(preterm and term cohorts)and total hospital length of stay (term cohorts)were shorter in FICare group.Use of Emergency Services after discharge was also lower in the FICare group CONCLUSIONS: Short and mid-term efficacy of FICare on health outcomes and family empowerment in a broader and highly-vulnerable neonatal population supports its generalization in complex healthcare neonatal services. IMPACT STATEMENT Scaling the FICare model to the critically ill, unstable premature and term infant is feasible and safe. The early intervention shows similar benefits in the short- and mid-term infants' outcomes in the whole spectrum of neonatal specialized care.

Abstract
Objectives: Inflammation contributes to disparate neurodevelopmental outcomes between preterm and term-born infants. In this context, DNA methylation may contribute to inflammation by affecting gene expression. Brain-derived neurotrophic factor (BDNF) and nuclear factor-kappa-B-inhibitor alpha (NFKBIA) are important genes for targeted DNA methylation analysis. The aims of this study were to (1) identify associations between inflammatory factors and BDNF and NFKBIA methylation, and (2) identify associations between BDNF and NFKBIA methylation and early neurobehavior in preterm infants. Methods: In a longitudinal cohort study of preterm infants born 28-31 weeks gestational age, blood samples were collected weekly for the quantification of inflammatory factors. We extracted DNA from saliva samples and quantified methylation of six BDNF cytosine-phosphate-guanine (CpG) sites and five NFKBIA CpG sites. Neurobehavior was assessed using the Neurobehavioral Assessment of the Preterm Infant. Results: Sixty-five infants were included in the analysis. In females, inflammatory factors were positively associated with BDNF methylation of most CpG sites. Interleukin-1 receptor antagonist was negatively associated with NFKBIA methylation at two CpG sites. In males, interleukin-6 was negatively associated with BDNF and NFKBIA methylation at most CpG sites. In females, BDNF methylation at two sites was inversely associated with motor performance. In males, NFKBIA methylation at one site was inversely associated with motor performance. Conclusion: This study provides evidence for the relationship between inflammation and neurobehavior in preterm infants, working mechanistically through DNA methylation. The finding of a difference between males and females suggests that female infants are potentially more vulnerable to inflammation and warrants future study.

Abstract
The aim of this study was to develop a real-time risk prediction model for extrauterine growth retardation (EUGR). A total of 2514 very preterm infants were allocated into a training set and an external validation set. The most appropriate independent variables were screened using univariate analysis and Lasso regression with tenfold cross-validation, while the prediction model was designed using binary multivariate logistic regression. A visualization of the risk variables was created using a nomogram, while the calibration plot and receiver operating characteristic (ROC) curves were used to calibrate the prediction model. Clinical efficacy was assessed using the decision curve analysis (DCA) curves. Eight optimal predictors that namely birth weight, small for gestation age (SGA), hypertensive disease complicating pregnancy (HDCP), gestational diabetes mellitus (GDM), multiple births, cumulative duration of fasting, growth velocity and postnatal corticosteroids were introduced into the logistic regression equation to construct the EUGR prediction model. The area under the ROC curve of the training set and the external verification set was 83.1% and 84.6%, respectively. The calibration curve indicate that the model fits well. The DCA curve shows that the risk threshold for clinical application is 0-95% in both set. Introducing Birth weight, SGA, HDCP, GDM, Multiple births, Cumulative duration of fasting, Growth velocity and Postnatal corticosteroids into the nomogram increased its usefulness for predicting EUGR risk in very preterm infants.

Abstract
OBJECTIVES To investigate the impact of proactive perinatal care on periviable preterm infants before and after its implementation. METHODS This retrospective cohort study was conducted over a period of 10 y, from 2013 to 2019, referred to as Phase I, and from 2020 to 2022, referred to as Phase II. A total of 162 eligible infants born between 220/7 and 256/7 wk of gestation were included in this analysis. RESULTS A total of 125 infants were born in phase I, and 37 infants in phase II received proactive care with minimal handling. The mortality decreased from 54.4% to 24.3% (P = 0.001). The composite outcomes of severe brain injury or death, sepsis or death and necrotizing enterocolitis or death were also improved with proactive care. Gestational age [adjusted odds ratio (aOR) 0.900; 95% confidence interval (CI), 0.836-0.970], air leak syndrome (aOR 4.958; 95% CI, 1.681-14.624), massive pulmonary hemorrhage (aOR 4.944; 95% CI, 2.055-11.893), and birth in phase II (aOR 0.324; 95% CI, 0.115-0.912) were independently associated with mortality. CONCLUSIONS The implementation of proactive care with minimal handling resulted in an increased survival rate and a reduction in the combined morbidities between the two time periods. The provision of proactive perinatal care with minimal handling is crucial for improving both the survival rates and clinical outcomes of these vulnerable infants.

Hypertensive Disorders of Pregnancy and Risk of Early Brain Abnormalities on Magnetic Resonance Imaging at Term among Infants Born at ≤32 Weeks' Gestational Age. J Pediatr 2024; 273:114133.

Abstract
OBJECTIVE To evaluate the proximal effects of hypertensive disorders of pregnancy (HDP) on a validated measure of brain abnormalities in infants born at ≤32 weeks' gestational age (GA) using magnetic resonance imaging at term-equivalent age. STUDY DESIGN In a multisite prospective cohort study, 395 infants born at ≤32 weeks' GA, underwent 3T magnetic resonance imaging scan between 39 and 44 weeks' postmenstrual age. A single neuroradiologist, blinded to clinical history, evaluated the standardized Kidokoro global brain abnormality score as the primary outcome. We classified infants as HDP-exposed by maternal diagnosis of chronic hypertension, gestational hypertension, pre-eclampsia, or eclampsia. Linear regression analysis identified the independent effects of HDP on infant brain abnormalities, adjusting for histologic chorioamnionitis, maternal smoking, antenatal steroids, magnesium sulfate, and infant sex. Mediation analyses quantified the indirect effect of HDP mediated via impaired intrauterine growth and prematurity and remaining direct effects on brain abnormalities. RESULTS A total of 170/395 infants (43%) were HDP-exposed. Adjusted multivariable analyses revealed HDP-exposed infants had 27% (95% CI 5%-53%) higher brain abnormality scores than those without HDP exposure (P = .02), primarily driven by increased white matter injury/abnormality scores (P = .01). Mediation analyses showed HDP-induced impaired intrauterine growth significantly (P = .02) contributed to brain abnormality scores (22% of the total effect). CONCLUSIONS Maternal hypertension independently increased the risk for early brain injury and/or maturational delays in infants born at ≤32 weeks' GA with an indirect effect of 22% resulting from impaired intrauterine growth. Enhanced prevention/treatment of maternal hypertension may mitigate the risk of infant brain abnormalities and potential neurodevelopmental impairments.

Abstract
Objectives: This study aimed to explore the associations of growth and body composition with gut microbiome and metabolome in preterm infants. Materials and Methods: A prospective cohort study including 73 human milk-fed very preterm infants was conducted. During hospitalization, fecal samples were collected to detect microbes and metabolites using 16S rRNA gene sequencing and liquid chromatography-mass spectrometry. Growth and body composition indices were measured at term equivalent age (TEA) and 6 months of corrected age (CA). Associations of the fecal microbiome and metabolome profiles with growth and body composition indices, as well as their changes, were analyzed. Results: A higher abundance of Streptococcus was associated with a lower fat-free mass (FFM) z-score at 6 months of CA (p = 0.002) and a smaller increase in FFM z-score from TEA to 6 months of CA (p = 0.018). Higher levels of 3'-sialyllactose and 6'-sialyllactose (6'-SL) in feces were correlated with a lower z-score of percentage body fat (PBF) (p = 0.018 and 0.020, respectively) and a lower z-score of fat mass (p = 0.044 and 0.043, respectively) at 6 months of CA. A higher level of 6'-SL in feces was correlated with a greater increase in FFM z-score from TEA to 6 months of CA (p = 0.021). Conclusions: This study sheds light on the role of specific microbial-host interactions in metabolic changes in preterm infants, indicating the potential role of sialylated human milk oligosaccharides in optimizing body composition.

Abstract
Adequate nutrition is necessary for achieving optimal growth and neurodevelopment. Growth is a natural and expected process that happens concomitantly with rapid advancements in neurodevelopment. Serial weight, length, and head circumference growth measures are essential for monitoring development, although identifying pathological deviations from normal growth can pose challenges. Appropriate growth assessments require considerations that a range of sizes for length, head circumference, and weight are expected and appropriate. Because of genetic differences and morbidities, there is a considerable overlap between the growth of healthy infants and those with growth alterations. Parents tend to be over-concerned about children who plot low on growth charts and often need reassurance. Thus, the use of terms such as "poor" growth or growth "failure" are discouraged when growth is approximately parallel to growth chart curves even if their size is smaller than specific percentiles. No specific percentile should be set as a growth goal; individual variability should be expected. An infant's size at birth is important information that goes beyond the common use of prognostic predictions of appropriate compared with small or large for gestational age. The lower the birthweight, the lower the nutrient stores and the more important the need for nutrition support. Compared to term infants, preterm infants at term-equivalent age have a higher percentage of body fat, but this diminishes over the next months. Current research findings support expert recommendations that preterm infants should grow, after early postnatal weight loss, similar to the fetus and then term-born infants, which translates to growth approximately parallel to growth chart curves. There is no need for a trade-off between optimum cognition and optimum future health. Each high-risk infant needs individualized nutrition and growth assessments. This review aims to examine infant growth expectations and messaging for parents of preterm and term-born infants within the broader causal framework.

Abstract
Background Diabetes in pregnancy (DIP) is associated with adverse fetal and maternal outcomes. DIP is classified as either pre-existing or new-onset diabetes mellitus (DM), which is classified into gestational DM (GDM) and newly detected type 2 (N-T2D). All pregnant women in Qatar who are not known to have pre-existing DM are offered screening for DIP during the first antenatal care visit and after 24 weeks gestation. The study aims to report the DIP screening rates, the prevalence of DIP, and the impact of the universal screening program on adverse pregnancy outcomes. Methods This retrospective study included all women who gave birth in Hamad Medical Corporation (HMC) hospitals between 2019 and 2022. New-onset DIP was defined using the WHO-2013 criteria. The primary outcomes were the screening rates and the prevalence of DIP in Qatar. The secondary outcomes were the difference in preterm delivery, C-section, macrosomia, large for gestational age (LGA), small for gestational age (SGA), and intra-uterine fetal death (IUFD) between women with or without GDM. Findings We included 94,422 women who gave birth to 96,017 neonates (85.7%) out of 112,080 neonates born nationwide. The number of women with pre-existing diabetes was 2496 women. Of 91,926 eligible women, 77,372 (84.2%) were screened for DIP. The prevalence of GDM is 31.6% (95% CI: 31.3-32.0%); N-T2D is 2.2% (95% CI: 2.1-2.3%), and pre-existing Type 2 DM and Type 1 DM was 2.6% (95% CI: 0.8-3.0%) and 0.2% (0.19-0.25), respectively. Compared to the non-GDM group, women with GDM were older (30.8 ± 5.3 versus 29.7 ± 5.2 years, p < 0.001). After adjusting for age, women with GDM had lower risk of IUFD and SGA (0.63 [95% CI 0.50-0.80, p < 0.001], 0.88 [95% CI 0.84-0.92, p < 0.001] respectively) but higher risk of C-section and LFD (1.07 [95% CI 1.04-1.10, p < 0.001], 1.09 [95% CI 1.01-1.15, p = 0.01], respectively, compared to women with no-GDM. Interpretation Of the women eligible for screening, 84.2% were screened by the DIP program in Qatar. The prevalence of DIP in Qatar is 36.9%. Integrated care is critical for the screening and management of diabetes during pregnancy. Fundings The authors did not receive any funding for this project.

The impact of reference growth standards on small- and large-for-gestational age outcomes among pregnancies conceived by fresh and frozen embryo transfers. F S Rep 2024; 5:164-169. [PMID: 38983739 PMCID: PMC11228793 DOI: 10.1016/j.xfre.2024.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 02/07/2024] [Accepted: 02/08/2024] [Indexed: 07/11/2024] Open
Abstract
Objective To describe differences in the frequency of small-for-gestational age (SGA) and large-for-gestational age (LGA) driven by different birth weight curves in assisted reproductive technology (ART)-conceived pregnancies. Design Retrospective cohort study. Setting Single academic medical center. Patients Singleton live births between the gestational ages of 36 weeks and 0 days and 42 weeks and 6 days from fresh or frozen embryo transfer (ET). Interventions None. Main Outcome Measures SGA (<10th percentile) and LGA (>90th percentile) classified by Fenton, INTERGROWTH-21, World Health Organization, Duryea, and Oken curves. Results The median birth weight and gestational age at birth among fresh ET pregnancies were 3,289g (interquartile range [IQR], 2,977-3,600g) and 39.4 (IQR, 38.6-40.3) weeks, respectively, and those among frozen ET pregnancies were 3,399g (IQR, 3,065-3,685g) and 39.4 (IQR, 38.7-40.1) weeks, respectively. The frequencies of SGA neonates using each birth weight standard ranged from 5.8% to 13.4% for fresh ET and from 3.5% to 8.7% for frozen ET. Those of LGA neonates ranged from 5.3% to 14.3% for fresh ET and from 6.6% to 21.2% for frozen ET. Conclusion The frequency of SGA and LGA neonates among ART-conceived gestations is partially driven by the birth weight standard. Selecting an appropriate standard that best reflects the patient population is critical to quantifying the risk of ART-conceived pregnancies.

Abstract
BACKGROUND Associations of 2-year neurodevelopmental and behavioral outcomes with growth trajectories of preterm infants are unknown. METHODS This secondary analysis of a preterm cohort examined in-hospital and discharge to 2-year changes in anthropometric z-scores. Two-year follow-up included Bayley Scales of Infant Development (BSID-III) and Child Behavior Checklist. RESULTS Among 590 infants, adjusted in-hospital growth was not associated with any BSID-III subscale. Occipitofrontal circumference (OFC) growth failure (GF) in-hospital was associated with increased adjusted odds of attention problems (aOR 1.65 [1.03, 2.65]), aggressive behavior (aOR 2.34 [1.12, 4.89]), and attention-deficit-hyperactivity symptoms (aOR 1.86 [1.05, 3.30]). Infants with OFC GF at 2 years had lower adjusted BSID-III language scores (-4.0 [-8.0, -0.1]), increased odds of attention problems (aOR 2.29 [1.11, 4.74]), aggressive behavior (aOR 3.09 [1.00, 9.56]), and externalizing problems (aOR 3.01 [1.07, 8.45]) compared to normal OFC growth cohort. CONCLUSION Infants with OFC GF are at risk for neurodevelopmental and behavioral impairment. CLINICAL TRIAL REGISTRATION This study is a secondary analysis of pre-existing data from the PENUT Trial Registration: NCT01378273.

Eye (Lond) 2024; 38:1462-1470. [PMID: 38212403 PMCID: PMC11126400 DOI: 10.1038/s41433-023-02921-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 12/06/2023] [Accepted: 12/21/2023] [Indexed: 01/13/2024] Open
Abstract
INTRODUCTION Retinopathy of prematurity (ROP) is a vision-threatening disease of premature infants. Practice guidelines recommend that all infants screened for ROP receive follow-up eye examinations to screen for ophthalmic complications.1 The purpose of this study was to identify risk factors for the development of strabismus, amblyopia, high refractive error, and cataracts among ROP-screened, non-treated infants. METHODS Retrospective single-centre study of ROP-screened, non-treated premature infants with ophthalmic follow-up. Clinical variables were screened for association with ocular findings at follow-up. Multivariable logistic regression was used to determine the risk factors associated with ocular findings. RESULTS 309 patients were seen for follow-up at 0.97 (0.69) [mean (SD)] years after neonatal intensive care unit (NICU) discharge. Strabismus was predicted by occipitofrontal circumference (OFC) z-score at NICU discharge (OR 0.61; 95% CI [0.42, 0.88]; p = 0.008), intraventricular haemorrhage (IVH) grade III or IV (OR 3.18; 95% CI [1.18, 8.54]; p = 0.02), and exclusive formula feeding at NICU discharge (OR 2.20; 95% CI [1.07, 4.53]; p = 0.03). Significant predictors of amblyopia were OFC z-score at discharge (OR 0.55; 95% CI [0.31, 0.96]; p = 0.03) and necrotising enterocolitis (NEC) (OR 6.94; 95% CI [1.38, 35.00]; p = 0.02). NEC was a significant risk factor for high refractive error (OR 7.27; 95% CI [1.39, 37.94]; p = 0.02). CONCLUSIONS Among premature infants screened but not treated for ROP, severe IVH, NEC, low OFC z-score, and exclusive formula feeding at NICU discharge were risk factors for ocular morbidity. These findings affirm the value of ophthalmic follow-up for all ROP-screened infants, particularly those with the identified risk factors.

Abstract
BACKGROUND Patent ductus arteriosus (PDA) is commonly encountered morbidity which often occurs as up to 60% of extremely preterm infants born at < 29 weeks gestational age (GA). PURPOSE This study aims to assess the clinical risk factors associated with PDA ligation among very low birth weight infants (VLBWI) and evaluate the neurodevelopmental outcomes of those who underwent PDA ligation. METHODS A total of 540 VLBWI were initially diagnosed with PDA in our 50-bed level IV NICU at Seoul St. Mary's Hospital, The Catholic University of Korea, between January 2015 and June 2023. Among these 540 VLBWI with PDA, only 221 had consistent hemodynamically significant (hs) PDA which required intervention including fluid restriction, medical treatment, or surgical ligation. In this study, only those 221 VLBWI with hsPDA who underwent neurodevelopmental assessment at corrected 18-24 months of age were included in this study analysis. RESULTS Out of 221 VLBWI diagnosed with hemodynamically significant (hs) PDA, 133 (60.2%) underwent PDA ligation, while the remaining 88 (39.8%) had their hs PDAs closed either medically or with fluid restriction. The mean gestational age and birth weight were significantly lower in PDA ligation group compared to no PDA ligation group (27.02 ± 2.17 vs. 27.98 ± 2.36, 907.31 ± 258.36 vs. 1006.07 ± 283.65, p = 0.001, 0.008). Resuscitation including intubation at delivery and intraventricular hemorrhage (IVH) (grade ≥ 3) were significantly higher in PDA ligation group. The clinical outcomes in the PDA ligation group revealed significantly worse oucomes compared to the no PDA ligation group. Both resuscitation, including intubation at delivery, and IVH (grade ≥ 3), consistently exhibited an increased risk for PDA ligation in a multivariable logistic regression analysis. Concerning neurodevelopmental outcomes, infants who underwent PDA ligation demonstrated significantly lower cognitive scores. However, only IVH (grade ≥ 3) and PVL were consistently associated with an increased risk of abnormal neurodevelopment at the corrected age of 18-24 months. CONCLUSION In our study, despite the consistent association between cognitive developmental delays in VLBWI who underwent PDA ligation, we observed that sicker and more vulnerable VLBWIs, specifically those experincing severe IVH, consistently exhibited an increased risk for both PDA ligation and abnormal neurodevelopment at the corrected age of 18-24 months.

Differences in autophagy marker levels at birth in preterm vs. term infants. Pediatr Res 2024:10.1038/s41390-024-03273-6.

Abstract
BACKGROUND Preterm infants are susceptible to oxidative stress and prone to respiratory diseases. Autophagy is an important defense mechanism against oxidative-stress-induced cell damage and involved in lung development and respiratory morbidity. We hypothesized that autophagy marker levels differ between preterm and term infants. METHODS In the prospective Basel-Bern Infant Lung Development (BILD) birth cohort we compared cord blood levels of macroautophagy (Beclin-1, LC3B), selective autophagy (p62) and regulation of autophagy (SIRT1) in 64 preterm and 453 term infants. RESULTS Beclin-1 and LC3B did not differ between preterm and term infants. However, p62 was higher (0.37, 95% confidence interval (CI) 0.05;0.69 in log2-transformed level, p = 0.025, padj = 0.050) and SIRT1 lower in preterm infants (-0.55, 95% CI -0.78;-0.31 in log2-transformed level, padj < 0.001). Furthermore, p62 decreased (padj-value for smoothing function was 0.018) and SIRT1 increased (0.10, 95% CI 0.07;0.13 in log2-transformed level, padj < 0.001) with increasing gestational age. CONCLUSION Our findings suggest differential levels of key autophagy markers between preterm and term infants. This adds to the knowledge of the sparsely studied field of autophagy mechanisms in preterm infants and might be linked to impaired oxidative stress response, preterm birth, impaired lung development and higher susceptibility to respiratory morbidity in preterm infants. IMPACT To the best of our knowledge, this is the first study to investigate autophagy marker levels between human preterm and term infants in a large population-based sample in cord blood plasma This study demonstrates differential levels of key autophagy markers in preterm compared to term infants and an association with gestational age This may be linked to impaired oxidative stress response or developmental aspects and provide bases for future studies investigating the association with respiratory morbidity.

Growth charts for use at birth and in the neonatal period: Recommendations of the French Neonatal Society. J Pediatr Gastroenterol Nutr 2024.

Abstract
INTRODUCTION The use of different growth charts can lead to confusion in discussions between professionals. There are obstetric charts (of fetal growth) and neonatal charts (of measurements at birth and of postnatal growth). These charts can be descriptive (derived from an unselected population) or prescriptive (derived from of a population at low risk and with optimal conditions for growth). OBJECTIVES (1) To describe available charts for infants at birth and in the neonatal period and compare them, and (2) to recommend one or more charts for use in neonatology in France. METHODS Bibliographic research was conducted on MEDLINE and completed by the guidelines of professional societies. RESULTS Antenatal information about fetal growth restriction (FGR) or fetuses identified as small-for-gestational-age using Intrauterine charts must be integrated into the identification of newborns at risk, but the use of Intrauterine charts to evaluate birthweight is not recommended to allow consistency with postnatal charts used in neonatal practice. Z-score variations using the updated Fenton postnatal charts are the most appropriate for the assessment of birthweight and postnatal growth for infants born preterm. These charts are sex-specific, include the three measurements (length, weight, and head circumference) and enable longitudinal follow-up of growth up to 50 weeks of corrected age and are linked to the WHO charts at term. The French Audipog charts, although are individualized, accessible online and can be used in maternity units to evaluate birthweight for term infants, but do not allow the follow-up of postnatal growth, while Fenton charts may be used to evaluate birthweight and postnatal growth in the first month for hospitalized term infants. CONCLUSION The updated Fenton charts are the neonatal charts that best suit the objectives of pediatricians in France for monitoring the growth of preterm newborns. The use of the Audipog charts at term remains an alternative in maternity wards, while Fenton charts can be used for hospitalized term newborns.

Abstract
OBJECTIVES To investigate factors associated with outcome of second twin during labour. METHODS The study was a retrospective cohort study in a single tertiary centre in Malaysia from 2014 until 2018 involving all twin pregnancies delivered at or more than 24 weeks of gestation. RESULTS Total of 409 twin pregnancies were included. Dichorionic twin comprises of 54.5 % (n=223) and 45.5 % (n=186) are monochorionic. Women with dichorionic pregnancies are significantly older (p<0.001), have more pre-existing medical disorders (p=0.011) and fetal structural anomalies (p=0.009). Monochorionic pregnancies are significantly more amongst Malay (p=0.01) and conceived spontaneously (p<0.001). There are significantly more fetuses both in cephalic presentation (p=0.026), birthweight discrepancy more than 20 % (p=0.038) and shorter mean inter-twin delivery duration (p=0.048) in monochorionic pregnancies. Second twin delivered with Apgar score <7 is significantly more in dichorionic pregnancies (p=0.006). The second twin is associated with lower birthweight, small for gestational age and arterial cord pH<7.25. Within the group of women who delivered both fetuses vaginally, there was significantly more second twins with intertwin delivery duration less than 30 min who were delivered vaginally without instrumentation (p=0.018). There was significantly more second twin with intertwin delivery duration of 30 min and more with arterial cord pH<7.25 (p=0.045). Those who delivered spontaneously had inter-twin delivery duration within 15-29 min. The outcome of second twin is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth. CONCLUSIONS The neonatal outcome for the second twin at birth is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth in a cohort managed with non-active management of the second twin in Malaysia.

The trajectory of head circumference and neurodevelopment in very preterm newborns during the first two years of life: a cohort study. J Pediatr (Rio J) 2024:S0021-7557(24)00067-6. [PMID: 38806152 DOI: 10.1016/j.jped.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 03/31/2024] [Accepted: 04/01/2024] [Indexed: 05/30/2024] Open
Abstract
OBJECTIVE To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. METHOD Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. RESULTS There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. CONCLUSION Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns.

Abstract
OBJECTIVE The relationship between adrenal insufficiency (AI), post-natal steroids (PNS) and neonatal acute kidney injury (AKI) remains understudied. We investigated associations between PNS and AKI in very low birthweight (VLBW) neonates, hypothesizing PNS is associated with reduced AKI. STUDY DESIGN We conducted a single-center retrospective review of VLBW infants comparing those with and without PNS exposure. Associations between PNS exposure and AKI were evaluated using generalized linear mixed-modeling adjusted for confounders. RESULT Of 567 neonates, 97 (17.1%) were exposed to PNS and 130 (22.9%) experienced AKI. Infants with PNS had lower gestational age, birthweight, Apgar scores, and experienced more AI versus those without PNS (all p < 0.05). PNS was associated with AKI (aRR 1.72, 95% CI 1.09-2.72) though hydrocortisone alone was not. CONCLUSION PNS exposure, but not hydrocortisone alone, is associated with increased AKI in VLBW neonates. Further analysis is needed to investigate the role of AI and AKI.

MATERNAL & CHILD NUTRITION 2024:e13663. [PMID: 38783411 DOI: 10.1111/mcn.13663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 04/09/2024] [Accepted: 04/25/2024] [Indexed: 05/25/2024]
Abstract
Post-natal growth influences short- and long-term preterm infant outcomes. Different growth charts, such as the Fenton Growth Chart (FGC) and INTERGROWTH-21st Preterm Post-natal Growth Standards (IG-PPGS), describe different growth curves and targets. This study compares FGC- and IG-PPGS-derived weight-for-postmenstrual age z-score (WZ) up to 50 weeks postmenstrual age (PMA50) for predicting 1-year anthropometry in 321 South African preterm infants. The change in WZ from birth to PMA50 (ΔWZ, calculated using FGC and IG-PPGS) was correlated to age-corrected 1-year anthropometric z-scores for weight-for-age (WAZ), length-for-age (LAZ), weight-for-length (WLZ) and BMI-for-age (BMIZ), and categorically compared with rates of underweight (WAZ < -2), stunting (LAZ < -2), wasting (WLZ < -2) and overweight (BMIZ > + 2). Multivariable analyses explored the effects of other early-life exposures on malnutrition risk. At PMA50, mean WZ was significantly higher on IG-PPGS (-0.56 ± 1.52) than FGC (-0.90 ± 1.52; p < 0.001), but ΔWZ was similar (IG-PPGS -0.26 ± 1.23, FGC -0.11 ± 1.14; p = 0.153). Statistically significant ΔWZ differences emerged among small-for-gestational age infants (FGC -0.38 ± 1.22 vs. IG-PPGS -0.01 ± 1.30; p < 0.001) and appropriate-for-gestational age infants (FGC + 0.02 ± 1.08, IG-PPGS -0.39 ± 1.18; p < 0.001). Correlation coefficients of ΔWZ with WAZ, LAZ, WLZ and BMIZ were low (r < 0.45), though higher for FGC than IG-PPGS. Compared with IG-PPGS, ΔWZ < -1 on FGC predicted larger percentages of underweight (42% vs. 36%) and wasting (43% vs. 39%) and equal percentages of stunting (33%), while ΔWZ > + 1 predicted larger percentages overweight (57% vs. 38%). Both charts performed similarly in multivariable analysis. Differences between FGC and IG-PPGS are less apparent when considering ΔWZ, highlighting the importance of assessing growth as change over time, irrespective of growth chart.
