Preschooler Screen Time During the Pandemic Is Prospectively Associated With Lower Achievement of Developmental Milestones.

The aim of this study was to assess the developmental risks associated with total screen time, and specifically newer mobile devices, in the context of the pandemic. This study uses parent-reported data from a prospective cohort of Canadian preschool-age children. The exposure variable is child daily screen time measured at the age of 3.5 years categorized as light (<1 hr/d), moderate (1-4 hr/d), or intensive (>4 hr/d) use (N = 315). Time spent on mobile devices was considered separately as a continuous variable. Our outcome is child global development scores, which combine assessments of communication, cognitive, personal-social, and motor skills measured at the age of 4.5 years using the Ages and Stages Questionnaire (ASQ) (N = 249, 79% retained). ASQ scores were dichotomized to distinguish children at risk of developmental delays (below the 15th percentile) from those not at risk. We estimate associations between child screen time and later global development using multiple regressions adjusted for child sex and temperament, and parent education. We also examine whether associations are moderated by child and parent characteristics. Logistic regressions revealed that intensive users were more at risk of global developmental delays compared with light users (OR = 4.29, p = 0.020). Mobile device use was also associated with lower global scores (β = -3.064; p = 0.028), but not with risk of delays. We found no evidence that associations were moderated by child sex and temperament, or parent education. The findings suggest that intensive screen time may be associated with delays in child global development. Early childhood professionals should encourage families with preschoolers to prioritize screen-free activities to promote optimal cognitive, language, social, and motor development.

Screening preterm-born infants for autistic traits may help to identify social communication difficulties at five years of age.

This study compared neurodevelopmental screening questionnaires completed when preterm-born children reached 2 years of corrected age with social communication skills at 5.5 years of age. Eligible subjects were born in 2011 at 24-34 weeks of gestation, participated in a French population-based epidemiological study and were free of motor and sensory impairment at 2 years of corrected age. The Ages and Stages Questionnaire (ASQ) and the Modified Checklist for Autism in Toddlers (M-CHAT) were used at 2 years and the Social Communication Questionnaire (SCQ) at 5.5 years of age. We focused on 2119 children. At 2 years of corrected age, the M-CHAT showed autistic traits in 20.7%, 18.5% and 18.2% of the children born at 24-26, 27-31 and 32-34 weeks of gestation, respectively (p = 0.7). At 5.5 years of age, 12.6%, 12.7% and 9.6% risked social communication difficulties, with an SCQ score ≥90th percentile (p = 0.2). A positive M-CHAT score at 2 years was associated with higher risks of social communication difficulties at 5.5 years of age (odds ratio 3.46, 95% confidence interval 2.04-5.86, p < 0.001). Stratifying ASQ scores produced similar results. Using parental neurodevelopmental screening questionnaires for preterm-born children helped to identify the risk of later social communication difficulties.

Primary care follow-up among children born with neonatal abstinence syndrome in a rural region in the United States

Introduction Children born with neonatal abstinence syndrome (NAS) have lower rates of preventive care utilization than children born without NAS, a pattern which is only partially explained by differences in social determinants of health (SDH). We sought to determine whether SDH and clinical characteristics were associated with well-child visit (WCV) attendance among children born with NAS in a rural academic health system. Methods Infants born at a single hospital in 2016–2018 were retrospectively included if they were diagnosed with non-iatrogenic NAS attributable to in utero opioid exposure and established care with an affiliated primary care clinic by 6 months of age. Healthcare utilization was tracked through the first 12 months of life. Independent variables included demographics, prenatal risk factors, insurance coverage, and SDH such as housing problems and food insecurity. Ages and Stages Questionnaire (ASQ) scores were extracted from the latest completed WCV during the first year of life. Results We identified 182 patients with NAS, of whom 80 established care with the primary care clinic, with a median of four WCVs (interquartile range: 2, 5) completed by 12 months of age. On unadjusted Poisson regression, none of the demographic, clinical, or SDH characteristics were associated with the number of completed WCVs. Among 44 patients with available ASQ data, the number of WCVs was not associated with ASQ scores at the latest WCV. Conclusions Within an academic rural health system, SDH and other infant or family characteristics did not predict WCV attendance among infants with NAS.

2301. Neurodevelopment in Infants with Antenatal or Early Neonatal Exposure to SARS-CoV-2

Abstract Background Antenatal and neonatal viral exposure may put the developing brain at risk for abnormal neurodevelopment. A clinical follow-up program was created in the Congenital Infection Program at Children’s National Hospital to follow infants with in utero or early life exposure to SARS-CoV-2. The aim of this study was to determine if infants with early SARS-CoV-2 exposure have abnormal neurodevelopment in infancy. Methods We performed a retrospective review of all infants evaluated in the follow-up program between 3/2020 – 11/2021. Demographic details, SARS-CoV-2 infection/testing data, pregnancy/birth data, and specialty consult and NICU records were extracted from infants’ medical charts. Infants were divided into 3 SARS-CoV-2 exposure groups: 1) antenatal exposure to symptomatic mother, 2) antenatal exposure to asymptomatic mother, 3) neonatal infection. All infants received a neurologic exam and developmental screening with the Ages and Stages Questionnaire (ASQ) in 5 domains (Communication, Gross Motor, Fine Motor, Problem Solving, Personal-Social) during their evaluation. The ASQ accounts for prematurity. Outcomes of interest were an abnormal neurologic exam or ASQ scores close to or below suggested cut-offs. Multivariate analysis was used to study correlations between exposure group and neurodevelopmental outcomes. Results Thirty-five infants were seen for up to 3 outpatient visits. Most infants (83%) were exposed in utero – 16 to symptomatic mothers (Group 1) and 12 to asymptomatic mothers (Group 2); 1 chart did not have symptom data. Six were exposed only as a neonate (Group 3). Group 1 had abnormal neurologic exams at mean (SD) age 112 (24) days (Table 1) and ASQ scores close to or below cut-offs for all domains (Fig. 1) more frequently than Groups 2 or 3. Group 1 was more likely to score below any ASQ cutoff compared to Group 2 (P=.04); of the 5 domains, differences were significant for Fine Motor (P=.01) and Personal-Social (P=.02). Conclusion Early SARS-CoV-2 exposure may impact infant development, especially among those exposed in utero to a symptomatic mother. Vaccination and other precautions to reduce spread and symptoms may protect against early neurodevelopmental delays. Future work should prioritize longitudinal follow-up of children with early SARS-CoV-2 exposure. Disclosures All Authors: No reported disclosures.

Neurodevelopment in infants with antenatal or early neonatal exposure to SARS-CoV-2

BackgroundAntenatal and neonatal viral exposure may put the developing brain at risk for abnormal neurodevelopment. A clinical program at Children's National Hospital provides detailed follow-up of infants with in utero or neonatal SARS-CoV-2 exposure. AimsTo determine impact of early SARS-CoV-2 exposure on neurodevelopment. Study designWe performed a prospective observational study of infant evaluations between 3/2020 and 11/2021. Demographics, pregnancy and birth details, SARS-CoV-2 data, specialty consultations, and NICU records were extracted from infants' medical records. Infants had neurologic exams and developmental screening with Ages and Stages Questionnaire (ASQ). Correlations between SARS-CoV-2 exposure type and neurodevelopmental outcomes were analyzed. SubjectsThirty-four infants evaluated in the SARS-CoV-2 follow-up program. Outcome measuresAbnormal neurologic exams or ASQ scores near or below suggested cut-offs. ResultsInfants received up to three evaluations. Most (28/34; 82 %) were exposed in utero – 16 to symptomatic mothers (IU-S) and 12 to asymptomatic mothers (IU-A). Six were exposed only as a neonate. IU-S had abnormal neurologic exams at mean (SD) age 112 (24) days and ASQ scores near or below cut-offs for all domains more frequently than IU-A or neonatally exposed infants. IU-S were more likely to score below any ASQ cutoff compared to IU-A (P = .04); differences were significant for Fine Motor (P = .01) and Personal-Social (P = .02) domains. ConclusionsEarly SARS-CoV-2 exposure may impact neurodevelopment, especially among infants exposed in utero to symptomatic gestational parents. Vaccination and other precautions to reduce early-in-life infection may protect against neurodevelopmental delays. Children with early SARS-CoV-2 exposure should have additional longitudinal screening for neurodevelopmental delays.

Effects of prenatal exposure to PM2.5 and its composition on cognitive and motor functions in children at 12 months of age: The Shanghai Birth Cohort Study

BackgroundPrenatal fine particulate matter (PM2.5) exposure has been linked to infant cognitive and motor functions, but the effects of PM2.5 chemical composition remain unclear. ObjectivesWe aimed to explore the associations of prenatal PM2.5 and its composition exposure with infant cognitive and motor functions. MethodsWe studied 2,435 mother-infant pairs in the Shanghai Birth Cohort Study. PM2.5 and its seven compositions [primary particles (black carbon, mineral dust and sea salts) and secondary particles (NH4+, NO3–, SO42- and organic matter)] during thethreetrimesters ofpregnancy were retrieved from the V4.CH.03 product developed by using a combined geoscience-statistical method. At the 12-month-old follow-up, infant cognitive and motor functions in five domains were assessed using the Ages and Stages Questionnaire (ASQ). We used multivariable linear regressions to estimate the effects of PM2.5 and its composition on the ASQ scores, for all infants and stratifying by sex and breastfeeding duration. ResultsPM2.5 exposure was negatively associated with gross motor, problem-solving and personal-social scores for all infants. PM2.5 compositions were inversely associated with ASQ scores in all five domains, and the effects of different compositions varied across domains. Specifically, all compositions except organic matter were correlated with lower problem-solving scores [e.g., (βSO42- = − 10.79, 95 % CI: −17.40, −4.18) ∼ (βNO3- = − 4.68, 95 % CI: −7.84, −1.53); for each 10 μg/m3 increase in PM2.5 compositions during the third trimester]. Primary and some secondary particles (organic matter, NO3–) were related to lower gross motor scores. Secondary particles were also inversely associated with communication (organic matter and NO3–), fine motor (NH4+, NO3–, SO42-) and personal-social (NH4+) scores. Additionally, boys and infants breastfed for < 6 months appeared to be more susceptible. ConclusionsWe found negative associations of PM2.5 and its compositions with infant cognitive and motor functions over a range of domains, especially the problem-solving domain.

Fetal neurosonography and infant neurobehavior following conception by assisted reproductive technology with fresh or frozen embryo transfer.

We aimed to explore fetal cortical brain development by neurosonography in fetuses conceived by assisted reproductive technology (ART), including frozen and fresh embryo transfer (ET), compared with those conceived spontaneously (SC), and to investigate its association with infant neurobehavior at 12 months of age. This was a prospective cohort study of 210 singleton pregnancies, including 70 SC pregnancies, 70 conceived by in-vitro fertilization (IVF) following frozen ET and 70 conceived by IVF after fresh ET. Fetal neurosonography was performed at 32 ± 2 gestational weeks to assess cortical development. Sulci depths were measured offline and normalized by biparietal diameter (BPD). Ages and Stages Questionnaires (ASQ) were completed postnatally, at 12 ± 1 months of corrected age. Neurosonographic findings were adjusted by regression analysis for maternal age, ethnicity, parity, fetal sex and fetal-weight centile and gestational age at scan, and ASQ scores were adjusted for maternal age, ethnicity, parity, educational level and employment status, gestational age at birth, breastfeeding, infant sex and infant age at the ASQ evaluation. Overall, in comparison to the SC fetuses, fetuses conceived by ART showed statistically significant differences in cortical development, with reduced parieto-occipital sulci depth adjusted for BPD (mean ± SD: fresh ET, 12.5 ± 2.5 vs frozen ET, 13.4 ± 2.6 vs SC, 13.4 ± 2.6, P < 0.001), cingulate sulci depth adjusted for BPD (median (interquartile range (IQR)): fresh ET, 5.8 (4.2-7.4) vs frozen ET, 5.8 (4.1-7.5) vs SC, 6.5 (4.8-7.8), P = 0.001) and calcarine sulci depth adjusted for BPD (median (IQR): fresh ET, 13.5 (10.1-16.1) vs frozen ET, 14.5 (12.1-15.8) vs SC, 16.4 (14.3-17.9), P < 0.001), together with lower Sylvian fissure grading score. Changes in cortical development were more pronounced in the fresh ET than in the frozen ET group. ART infants showed lower ASQ scores as compared to SC infants, particularly in the fresh ET group (mean ± SD global ASQ Z-score: fresh ET, -0.3 ± 0.4 vs frozen ET, -0.2 ± 0.4 vs SC, 0 ± 0.4, P < 0.001). Fetuses conceived by ART show a distinctive pattern of cortical development and suboptimal infant neurodevelopment, with more pronounced changes in those conceived following fresh ET. These findings support the existence of in-utero brain reorganization associated with ART and warrant follow-up studies to assess its long-term persistence. © 2022 The Authors.

Utility of the Ages and Stages Questionnaire to Identify Developmental Delay in Children Aged 12 to 60 Months

The Ages and Stages Questionnaire (ASQ) is a commonly used developmental screening tool, but its utility is debated. To conduct a a systematic review and meta-analysis to evaluate ASQ's utility as a screening or diagnostic tool to identify developmental delay in children aged 12-60 months. Medline, EMBASE, CINAHL, PsycINFO, and Mednar were searched from inception until December 2021. Studies meeting both criteria were included. ASQ was performed at age 12 to 60 months or where the median age at ASQ was at least 12 months and formal developmental assessments were done within 2 months of ASQ. True positive, false positive, false negative, and true negatives from individual studies were extracted. Meta-analysis was conducted with Stata version 16.1. Risk of bias was assessed using the QUADAS-2 tool. Certainty of evidence (COE) was assessed using GRADE guidelines. Ability of ASQ scores more than 2 SDs below the mean in more than 1 domain (ASQ-2SD) to identify any developmental delay or severe delay. Based on generally accepted interpretation of likelihood ratio (LR) values, a positive LR (PLR) more than 5 and a negative LR (NLR) of 0.2 or less were considered necessary to rule in or rule out developmental delay, respectively, with at least moderate probability. Initial search yielded 5777 citations of which 43 were included in the review. Of them, 36 were included in the meta-analysis. The pooled sensitivity, specificity, PLR, and NLR are as follows: ASQ-2SD to predict any delay in 1 or more domain (n = 16), 0.77 (95% CI, 0.64-0.86), 0.81 (95% CI, 0.75-0.86), 4.10 (95% CI, 3.17-5.30), and 0.28 (95% CI, 0.18-0.44); ASQ-2SD to predict severe delay in 1 or more domain (n = 15), 0.84 (95% CI, 0.75-0.90), 0.77 (95% CI, 0.71-0.82), 3.72 (95% CI, 2.98-4.64), and 0.20 (95% CI, 0.13-0.32); ASQ-2SD motor domain to predict motor delay (n = 7), 0.41 (95% CI, 0.26-0.57), 0.94 (95% CI, 0.87-0.97), 6.5 (95% CI, 3.8-11.1), and 0.63 (95% CI, 0.50-0.81); and ASQ-2SD cognitive domain to predict cognitive delay (n = 2), 0.44 (95% CI, 0.24-0.65), 0.93 (95% CI, 0.81-0.95), 6.4 (95% CI, 2.4-16.8), and 0.61 (95% CI, 0.43-0.86). The COE was low/very low. If a child aged 12 to 60 months passes all ASQ domains, there is a moderate probability that they do not have severe developmental delay (low COE). If a child aged 12-60 months fails the motor or cognitive domain of ASQ, there is a moderate probability that they have some motor or cognitive delay, respectively (very low COE).

A correlation between Magnetic Resonance Spectroscopy (1-H MRS) and the neurodevelopment of two-year-olds born preterm in an EPIRMEX cohort study.

BackgroundPreterm infants are at risk of neurodevelopmental impairments. At present, proton magnetic resonance spectroscopy (1H-MRS) is currently used to evaluate brain metabolites in asphyxiated term infants. The purpose of this study was to identify in the preterm EPIRMEX cohort any correlations between (1H-MRS) metabolites ratio at term equivalent age (TEA) and neurodevelopmental outcomes at 2 years.MethodsOur study included EPIRMEX eligible patients who were very preterm infants (gestational age at birth ≤32 weeks) and who underwent a brain MRI at TEA and 1H-MRS using a monovoxel technique. The volumes of interest (VOI) were periventricular white matter posterior area and basal ganglia. The ratio of N Acetyl Aspartate (NAA) to Cho (Choline), NAA to Cr (creatine), Cho to Cr, and Lac (Lactate) to Cr were measured. Neurodevelopment was assessed at 24 months TEA with ASQ (Ages and Stages Questionnaire).ResultsA total of 69 very preterm infants had a 1H-MRS at TEA. In white matter there was a significant correlation between a reduction in the NAA/Cho ratio and a total ASQ and/or abnormal communication score, and an increase in the Lac/Cr ratio and an abnormality of fine motor skills. In the gray nuclei there was a trend correlation between the reduction in the NAA/Cho ratio and sociability disorders; and the increase in the Lac/Cr ratio and an anomaly in problem-solving.ConclusionsUsing NAA as a biomarker, the vulnerability of immature oligodendrocytes in preterm children at TEA was correlated to neurodevelopment at 2 years. Similarly, the presence of lactate at TEA was associated with abnormal neurodevelopment at 2 years in the preterm brain.

Prenatal fine particulate matter exposure associated with placental small extracellular vesicle derived microRNA and child neurodevelopmental delays

Background and aimsPrenatal fine particulate matter (PM2.5) exposure has been linked to adverse neurodevelopment. However, epidemiological evidence remains inconclusive and little information about the effects of various PM2.5 components on child neurodevelopment is currently known. The underlying mechanism was also not elucidated. The study aimed to evaluate the effects of PM2.5 and components exposure on child neurodevelopmental delays and the role of placental small extracellular vesicles (sEVs)-derived miRNAs in the associations. MethodsWe included 267 mother-child pairs in this analysis. Prenatal PM2.5 and components (i.e. elements, water-soluble ions, and PAHs) exposure during three trimesters were monitored through personal PM2.5 sampling. Child neurodevelopment at 2, 6, and 12 months old were evaluated by Ages and Stages Questionnaire (ASQ). We isolated sEVs from placental tissue to analyze the change of sEVs-derived miRNAs in response to PM2.5. Associations between the PM2.5-associated miRNAs and child neurodevelopment were evaluated using multivariate linear regression models. ResultsThe PM2.5 exposure levels in the three trimesters range from 2.51 to 185.21 μg/m3. Prenatal PM2.5 and the components of Pb, Al, V and Ti exposure in the second and third trimester were related to decreased ASQ scores communication, problem-solving and personal-social domains in children aged 2 or 6 months. RNA sequencing identified fifteen differentially expressed miRNAs. The miR-101-3p and miR-520d-5p were negatively associated with PM2.5 and Pb component. miR-320a-3p expression was positively associated with PM2.5 and V component. Meanwhile, the miR-320a-3p was associated with decreased ASQ scores, as reflected by ASQ-T (β: -2.154, 95 % CI: −4.313, −0.516) and problem-solving domain (β: -0.605, 95 % CI: −1.111, −0.099) in children aged 6 months. ConclusionPrenatal exposure to PM2.5 and its Pb, Al, V & Ti component were associated with infant neurodevelopmental delays. The placenta sEVs derived miRNAs, especially miR-320a-3p, might contribute to an increased risk of neurodevelopmental delays.

0512 Concurrent and longitudinal linkages between bedtime routines and social-emotional development in toddlers

Abstract Introduction Sleep is important for optimal development in early childhood. Instituting a consistent bedtime routine is an empirically supported behavioral intervention to promote early childhood sleep health. However, prior work has focused on the benefits of a bedtime routine for sleep outcomes, with little research on its potential benefits to social-emotional development. Thus, the current study examined concurrent and longitudinal associations between a consistent bedtime routine (defined as 5 or more nights per week) and social-emotional development in toddlers (ages 12.0 to 19.9 months). Methods Caregivers of 32 infants (M = 12.5mos, 59.4% female) completed baseline questionnaires about the frequency of their child’s bedtime routine and other evening activities at their scheduled 12-month well-child visit. At their child’s 15-month well visit, caregivers completed questionnaires including items on bedtime routine frequency, the communication and personal-social subscales of the Ages and Stages Questionnaire (ASQ), and the Brief Infant-Toddler Social and Emotional Assessment (BITSEA). Results Over half (59.4%) of caregivers reported a consistent child bedtime routine at 12 months and nearly three quarters (71.9%) reported a consistent bedtime routine at 15 months. Linear regression showed that having a consistent bedtime routine at 15 months was significantly associated with fewer concurrent social-emotional problems on the BITSEA, B = -2.40, p = .009, 95% CI [-3.86, -.94]. Toddlers who scored above the BITSEA cutoff for social-emotional concerns (31.3%) were engaged in a consistent bedtime routine less frequently (M = 4.50 nights/week) than those below the cutoff (M = 6.18 nights/week), p = .004, η2 = .24. However, bedtime routine frequency at 12 months did not predict 15-month BITSEA concerns, p&amp;gt;.05. No associations emerged between bedtime routine frequency at 12 or 15 months and the communication and personal-social ASQ scores. Conclusion A consistent bedtime routine is concurrently, but not longitudinally, associated with positive social-emotional development, including less frequent clinically significant concerns, in toddlers at 15 months of age. Bedtime routine frequency was not linked to communication or personal-social interactions. Implementing a consistent bedtime routine may be a feasible method to promote toddlers’ social-emotional development within the context of concerns.

Early life exposure to indoor air pollutants and the risk of neurodevelopmental delays: The Japan Environment and Children's Study.

Air pollution has been associated with childhood neurodevelopment. However, the role of indoor air pollution, especially volatile organic compounds (VOCs), on childhood neurodevelopment has been poorly explored to date. We investigated the association between indoor air pollutants and childhood neurodevelopment in 5,017 randomly selected children from the Japan Environment and Children's Study. When the participants reached 1.5 and 3years of age, they were followed up with home visits and neurodevelopmental tests using the Ages and Stages Questionnaire (ASQ). At both ages, we collected indoor air samples for 1week and measured 13 indoor air pollutants: particulate matter with an aerodynamic diameter of≤2.5μm, ozone, nitrogen dioxide, sulfur dioxide, and nine VOCs. The associations between air pollutants and ASQ scores were estimated using linear mixed effects models and weighted quantile sum regressions (WQS) at each age separately. Stratified analysis by sex was conducted. Exposure to m,p-xylene at the age of 3 was associated with lower communication, fine motor, and overall ASQ scores (coefficients: -0.18 [99% confidence intervals (CI): -0.35, -0.02], -0.23 [99%CI: -0.43, -0.03], and-0.72 [99%CI: -1.41, -0.04] per 1µg/m3 increase, respectively). Exposure to o-xylene at the age of 3 was associated with lower communication, gross motor, fine motor, and overall ASQ scores (coefficients: -0.48 [99%CI: -0.90, -0.07], -0.45 [99%CI: -0.78, -0.13], -0.65 [99%CI: -1.14, -0.16], and-2.15 [99%CI: -3.83, -0.47] per 1µg/m3 increase, respectively). The WQS index was associated with lower gross motor ASQ scores at the age of 3 (coefficient: -0.27 [95%CI: -0.51, -0.03] for one-unit WQS index increases), which was attributed to benzene (33.96%), toluene (26.02%), o-xylene (13.62%), and ethylbenzene (9.83%). Stratified analysis showed similar results. Although further investigations are required, our results suggest an association of neurodevelopmental delays with indoor low-level exposure to m,p-xylene and o-xylene in early life.

Association of maternal sleep before and during pregnancy with sleep and developmental problems in 1-year-old infants

This study investigated the association of maternal sleep before and during pregnancy with sleeping and developmental problems in 1-year-old infants. We used data from the Japan Environment and Children’s Study, which registered 103,062 pregnancies between 2011 and 2014. Participants were asked about their sleep habits prior to and during pregnancy. Follow-up assessments were conducted to evaluate the sleep habits and developmental progress of their children at the age of 1 year. Development during infancy was evaluated using the Ages and Stages Questionnaire (ASQ). Maternal short sleep and late bedtime before and during pregnancy increased occurrence of offspring’s sleeping disturbances. For example, infants whose mothers slept for less than 6 h prior to pregnancy tended to be awake for more than 1 h (risk ratio [RR] = 1.49, 95% confidence interval [CI] 1.34–1.66), sleep less than 8 h during the night (RR = 1.60, 95% CI 1.44–1.79), and fall asleep at 22:00 or later (RR = 1.33, 95% CI 1.26–1.40). Only subjective assessments of maternal sleep quality during pregnancy, such as very deep sleep and feeling very good when waking up, were inversely associated with abnormal ASQ scores in 1-year-old infants.

Perinatal mental health outcome measures in a mother and baby unit

AimsTo Audit Perinatal outcome measures and understand better the population served in order to improve care and understand risks. Our audit standards inculded: paired HoNOS and PBQ recorded on admission and discharge as well as ASQ scores prior to admission.MethodHealth of the Nation Outcome Scales (HoNOS), Postpartum Bonding Questionnaire (PBQ) and Ages and Stages Questionnaires (ASQ) were recorded on Lorenzo and SystmOne. Scores were collected over 20 months within the same MBU and these were analyzed.ResultOur audit standards had an overall audit compliancy of 73% with paired HoNOS better than PBQ. Mental health severity mitigated and maternal bonding improved to a significant degree. Depression was the principal presentation as were patients from deprived areas. Only 55% of babies had ASQ scores completed appropriately pre- admission.ConclusionAs the newest MBU in the country, this an initial foray of perinatal outcomes. Gratifyingly, benefits of MBU admission for mother and baby is evidenced in this snapshot.

Effect of Delayed Cord Clamping on Neurodevelopment at 3 Years: A Randomized Controlled Trial

Introduction: Iron deficiency (ID) is associated with poor neurodevelopment. We have previously shown that delayed umbilical cord clamping (CC) improves iron stores at 8 months and neurodevelopment at 1 year in term, healthy infants in Nepal. Objective: The aim of this study was to assess the effects of delayed CC (≥180 s) compared to early CC (≤60 s) on neurodevelopment using the Ages and Stages Questionnaire (ASQ) at age 3 years. Methods: In 2014, 540 healthy Nepalese infants born at term were randomized in a 1:1 ratio to delayed or early CC. At 3 years of age, ASQ assessment was performed by phone interviews with parents. A score >1 standard deviation below the mean was defined as “at risk” for developmental impairment. Results: At 3 years of age, 350 children were followed up, 170 (63.0%) in the early CC group and 180 (66.7%) in the delayed CC group. No significant differences in ASQ scores in any domains between groups were found. However, more girls were “at risk” for affected gross motor development in the early CC group: 14 (18.9%) versus 6 (6.3%), p = 0.02. Conclusion: There were no significant differences in ASQ scores in any domains between groups. In the subgroup analysis, fewer girls who underwent delayed CC were “at risk” for delayed gross motor development. Due to the pronounced difference in iron stores at 8 months postpartum in this cohort, follow-up studies at an older age are motivated since neurodevelopmental impairment after early ID may be more detectable with increasing age.

Prenatal exposure to ambient fine particulate matter and early childhood neurodevelopment: A population-based birth cohort study

Although previous studies have reported the adverse effect of air pollution exposure during pregnancy on neurodevelopment in children, epidemiological evidence is limited, and the results are inconsistent. This study aimed to explore the association between prenatal ambient fine particulate matter (PM2.5) exposure and early childhood neurodevelopment in a large birth cohort study of 4009 maternal-child pairs. Prenatal daily PM2.5 exposure concentrations at 1 km spatial revolution were estimated using high-performance machine-learning models. Neurodevelopmental outcomes of children at ages 2, 6, 12, and 24 months were assessed using the Ages and Stages Questionnaire (ASQ). Distributed lag nonlinear models were used to identify critical windows of prenatal PM2.5 exposure. General linear mixed models with binomially distributed errors were used to estimate the effect of prenatal PM2.5 exposure on suspected developmental delay (SDD) in five developmental domains based on the longitudinal design. Prenatal PM2.5 exposure was significantly associated with decreased scores for all neurodevelopmental domains of children at ages 2, 6, and 24 months. Each 10-μg/m3 increase in PM2.5 exposure was significantly associated with increased risk of SDD for all subjects (RR: 1.52 95% CI: 1.19, 2.03), specifically, in problem-solving domain for girls (RR: 2.23, 95% CI: 1.22, 4.35). Prenatal PM2.5 exposure in weeks 18 to 34 was significantly associated with both ASQ scores and SDDs. Our study proposed that prenatal PM2.5 exposure affected early childhood neurodevelopment evaluated with the ASQ scale. PM2.5 exposure might increase the risk of SDD for boys and girls, specifically in the problem-solving domain for girls.

Influence of physical activity before and during pregnancy on infant\u2019s sleep and neurodevelopment at 1-year-old

The aim of this study was to investigate the association between maternal physical activity (PA) before and during pregnancy and sleep and developmental problems in 1-year-old infants. We used data from a nationwide cohort study in Japan that registered 103,062 pregnancies between 2011 and 2014. Participants were asked about their PA before and during pregnancy, and the sleep and development of their children at the age of 1 year. Maternal PA was estimated using the International Physical Activity Questionnaire and was expressed in METs per week. We defined scores below the cut-off points of the Ages and Stages Questionnaire (ASQ) as abnormal for infant development. Based on the levels of PA before or during pregnancy, the participants were divided into five groups. In mothers with higher PA levels, the risk ratio for bedtime after 22:00 or abnormal ASQ scores in their 1-years-old infants were lower. These associations were observed for PA before and during pregnancy. Higher levels of maternal PA, both before and during pregnancy, may reduce sleep and developmental problems in infants.

Automated brain MRI metrics in the EPIRMEX cohort of preterm newborns: Correlation with the neurodevelopmental outcome at 2 years

PurposeThe purpose of this study was to identify in the EPIRMEX cohort the correlations between MRI brain metrics, including diffuse excessive high signal intensities (DEHSI) obtained with an automated quantitative method and neurodevelopmental outcomes at 2 years. Materials and methodsA total of 390 very preterm infants (gestational age at birth≤32 weeks) who underwent brain MRI at term equivalent age at 1.5T (n=338) or 3T (n=52) were prospectively included. Using a validated algorithm, automated metrics of the main brain surfaces (cortical and deep gray matter, white matter, cerebrospinal fluid) and DEHSI with three thresholds were obtained. Linear adjust regressions were performed to assess the correlation between brain metrics with the ages and stages questionnaire (ASQ) score at 2 years. ResultsBasal ganglia and thalami, cortex and white matter surfaces positively and significantly correlated with the global ASQ score. For all ASQ sub-domains, basal ganglia and thalami surfaces significantly correlated with the scores. DEHSI was present in 289 premature newborns (74%) without any correlation with the ASQ score. Metrics of DEHSI were greater at 3T than at 1.5T. ConclusionBrain MRI metrics obtained in our multicentric cohort correlate with the neurodevelopmental outcome at 2 years of age. The quantitative detection of DEHSI is not predictive of adverse outcomes. Our automated algorithm might easily provide useful predictive information in daily practice.

Neurodevelopment at 2 years and umbilical artery Doppler in cases of very preterm birth after prenatal hypertensive disorder or suspected fetal growth restriction: EPIPAGE-2 prospective population-based cohort study.

To investigate the association between absent or reversed end-diastolic flow (ARED) on umbilical artery Doppler ultrasound and poor neurological outcome at 2 years of age after very preterm birth associated with suspected fetal growth restriction (FGR) or maternal hypertensive disorders. The study population comprised all very preterm (22-31 completed weeks) singleton pregnancies delivered because of suspected FGR and/or maternal hypertensive disorders that had umbilical artery Doppler and 2-year follow-up available included in EPIPAGE-2, a prospective, nationwide, population-based cohort of preterm births in France in 2011. Univariate and two-level multivariable logistic regression analyses were used to assess the association of ARED in the umbilical artery, as compared with normal or reduced end-diastolic flow, with severe or moderate neuromotor and/or sensory disability and with an Ages and Stages Questionnaire (ASQ) score below a threshold. This was defined as a score more than 2 SD below the mean in any of the five domains, at age 2, adjusting for gestational age at delivery. ASQ is used to identify children at risk of developmental delay requiring reinforced follow-up and further evaluation. Descriptive statistics and bivariate tests were weighted according to the duration of the inclusion periods. The analysis included 484 children followed up at 2 years of age, for whom prenatal umbilical artery Doppler ultrasound was available. Among them, 8/484 (1.6%) had severe or moderate neuromotor and/or sensory disability, and 156/342 (45.4%) had an ASQ score below the threshold. Compared with normal or reduced end-diastolic flow in the umbilical artery (n = 305), ARED (n = 179) was associated with severe or moderate neuromotor and/or sensory disability (adjusted odds ratio (OR), 11.3; 95% CI, 1.4-93.2) but not with an ASQ score below the threshold (adjusted OR, 1.2; 95% CI, 0.8-1.9). Among children delivered before 32 weeks of gestation due to suspected FGR and/or maternal hypertensive disorder who survived until 2years of age, prenatal ARED in the umbilical artery was associated with a higher incidence of severe or moderate neuromotor and/or sensory disability.
