Parenting stress in infancy was associated with neurodevelopment in 24-month-old children with congenital heart disease.

AIM: Having a child with congenital heart disease (CHD) is stressful for parents, but research on the impact this stress can have on child development has been lacking. We investigated the associations between parenting stress when children were infants and neurodevelopmental outcomes in toddlers with CHD. METHODS: This study was carried out at the Neurocardiac Clinic at the Sainte-Justine University Hospital in Montréal, Canada. Patients born from 2012 to 2019 and followed up to 24 months of age were recruited. Parenting stress levels were measured when the child was 4-6 months and 24 months and the child's neurodevelopment was assessed at 24 months. Multiple linear regressions analyses were carried out. RESULTS: We studied 100 children (56% boys) with CHD. Most of the parenting stress scores were below the clinical threshold. However, they accounted for a significant part of the variance in the children's cognitive (15%-16%), receptive language (14%-15%) and gross motor outcomes (15%-18%). They had no impact on the children's expressive language or fine motor outcomes. CONCLUSION: Higher parenting stress was associated with poorer neurodevelopmental outcomes in toddlers with CHD. Early screening of parenting stress in CHD clinics is necessary to provide individualised intervention for parents and optimise neurodevelopmental outcomes in children.

How to measure patient and family important outcomes in extremely preterm infants: A scoping review.

AIM: Parents of children born preterm have identified outcomes to be measured for audit and research at 18-24 months of age: child well-being, quality of life/function, socio-emotional/behavioural outcomes, respiratory, feeding, sleeping, and caregiver mental health. The aim was to identify the best tools to measure these seven domains. METHODS: Seven working groups completed literature reviews and evaluated potential tools to measure these outcomes in children aged 18-24 months. A group of experts and parents voted on the preferred tools in a workshop and by questionnaire. Consensus was 80% agreement. RESULTS: Consensus was obtained for seven brief, inexpensive, parent friendly valid measures available in English or French for use in a minimum dataset and potential alternative measures for use in funded research. CONCLUSION: Valid questionnaires and tools to measure parent-identified outcomes in young preterm children exist. This study will facilitate research and collection of data important to families.

Language brain responses and neurodevelopmental outcome in preschoolers with congenital heart disease: A fNIRS study.

Neurodevelopmental disabilities affect up to 50% of survivors of congenital heart disease (CHD). Language difficulties are frequently identified during preschool period and can lead to academic, social, behavioral, and emotional difficulties. Structural brain alterations are associated with poorer neurodevelopmental outcomes in patients with CHD during infancy, childhood, and adolescence. However, evidence is lacking about the functional brain activity in children with CHD and its relationship with neurodevelopment. This study therefore aimed to characterize brain responses during a passive story-listening task in 3-year-old children with CHD, and to investigate the relationship between functional brain patterns of language processing and neurodevelopmental outcomes. To do so, we assessed hemodynamic concentration changes, using functional near-infrared spectroscopy (fNIRS), and neurodevelopmental outcomes, using the Wechsler Preschool and Primary Scale of Intelligence - 4th Edition (WPPSI-IV), in children with CHD (n = 19) and healthy controls (n = 23). Compared to their healthy peers, children with CHD had significantly lower scores on the Verbal comprehension index (VCI), the Vocabulary acquisition index (VAI), the General ability index (GAI), and the Information and the Picture Naming subtests of the WPPSI-IV. During the passive story-listening task, healthy controls showed significant hemodynamic brain responses in the temporal and the temporal posterior regions, with stronger activation in the temporal posterior than in the temporal regions. In contrast, children with CHD showed reduced activation in the temporal posterior regions compared to controls, with no difference of activation between regions. Reduced brain responses in the temporal posterior regions were also correlated with lower neurodevelopmental outcomes in both groups. This is the first study that reveals reduced brain functional responses in preschoolers with CHD during a receptive language task. It also suggests that the temporal posterior activation could be a potential brain marker of cognitive development. These findings provide support for the feasibility of identifying brain correlates of neurodevelopmental vulnerabilities in children with CHD.

Corrected Age at Bayley Assessment and Developmental Delay in Extreme Preterms.

BACKGROUND AND OBJECTIVES: Research on outcomes of prematurity frequently examines neurodevelopment in the toddler years as an end point, but the age range at examination varies. We aimed to evaluate whether the corrected age (CA) at Bayley-III assessment is associated with rates of developmental delay in extremely preterm children. METHODS: This retrospective cohort study included children born at <29 weeks' gestation who were admitted in the Canadian Neonatal Network between 2009 and 2017. The primary outcomes were significant developmental delay (Bayley-III score <70 in any domain) and developmental delay (Bayley-III score <85 in any domain). To assess the association between CA at Bayley-III assessment and developmental delay, we compared outcomes between 2 groups of children: those assessed at 18 to 20 months' CA and 21-24 months. RESULTS: Overall, 3944 infants were assessed at 18-20 months' CA and 881 at 21-24 months. Compared with infants assessed at 18-20 months, those assessed at 21-24 months had higher odds of significant development delay (20.0% vs 12.5%; adjusted odds ratio, 1.75; 95% confidence interval [CI], 1.41-2.13) and development delays (48.9% vs 41.7%, adjusted odds ratio 1.33; 95% CI, 1.11-1.52). Bayley-III composite scores were on average 3 to 4 points lower in infants evaluated at 21-24 months' CA (for instance, adjusted mean difference and 95% CI for language: 3.49 [2.33-4.66]). Conversely, rates of cerebral palsy were comparable (4.6% vs 4.7%) between the groups. CONCLUSIONS: Bayley-III assessments performed at 21-24 months' CA were more likely to diagnose a significant developmental delay compared with 18- to 20-month assessments in extremely preterm children.

Antidepressants use during pregnancy and child psychomotor, cognitive and language development at 2 years of age-Results from the 3D Cohort Study.

Introduction: Approximately 5.5% of pregnant women take antidepressants. Studies on prenatal exposure to antidepressants reported no association with child cognition, and inconsistent results with motor function and language development. A limitation has been the failure to adjust for prenatal maternal distress. Objectives: Assess the associations between prenatal exposure to antidepressants and child development at age two, while adjusting for maternal depressive symptoms and stress during pregnancy. Explore indirect effects through birth complications and consider sex-specific associations. Methods: This is an ancillary study of the 3D (Design Develop, Discover) Study initiated during pregnancy. Data on antidepressants were collected through medication logs spanning the entire pregnancy. Depressive symptoms and stress were assessed during pregnancy by self-reported questionnaires, motor and cognitive development with the Bayley Scales of Infant and Toddler Development (BSID-III), and language development with the MacArthur Communicative Development Inventories at age 2. Multiple linear regressions were used to assess the associations between exposure and developmental outcomes. Mediation models were used to assess indirect effects. Interaction terms were introduced to assess sex-specific associations. Results: 1,489 mother-child dyads were included, of whom 61 (4.1%) reported prenatal antidepressant use. Prenatal exposure was negatively associated with motor development (B = -0.91, 95% CI -1.73, -0.09 for fine motor, B = -0.89, 95% CI -1.81, 0.02 for gross motor), but not with cognitive (B = -0.53, 95% CI -1.82, 0.72) and language (B = 4.13, 95% CI -3.72, 11.89) development. Adjusting for maternal prenatal distress only slightly modified these associations. No indirect effect or differential effect according to child sex were found. Conclusion: This study supports evidence of a negative association between prenatal exposure to antidepressants and motor development at age two, after adjusting for maternal distress, but the effect size remains very small, with about only one BSID-III point lower in average.

A Parent-child yoga intervention for reducing attention deficits in children with congenital heart disease: the Yoga for Little Hearts Feasibility Study Protocol.

INTRODUCTION: Preschoolers and school-aged children with congenital heart disease (CHD) are at higher risk of attention deficit hyperactivity disorder (ADHD) compared with the general population. To this day, no randomised controlled trial (RCT) aiming to improve attention has been conducted in young children with CHD. There is emerging evidence indicating that parent-child yoga interventions improve attention and reduce ADHD symptoms in both typically developing and clinical populations. METHODS AND ANALYSIS: This is a single-blind, two-centre, two-arm trial during which 24 children with CHD and their parents will be randomly assigned to (1) a parent-child yoga intervention in addition to standard clinical care or (2) standard clinical care alone. All participants will undergo standardised assessments: (1) at baseline, (2) immediately post-treatment and (3) 6 months post-treatment. Descriptive statistics will be used to estimate the feasibility and neurodevelopmental outcomes. This feasibility study will evaluate: (1) recruitment capacity; (2) retention, drop-out and withdrawal rates during the yoga programme and at the 6-month follow-up; (3) adherence to the intervention; (4) acceptability of the randomisation process by families; (5) heterogeneity in the delivery of the intervention between instructors and use of home-based exercises between participants; (6) proportion of missing data in the neurodevelopmental assessments and (7) SD of primary outcomes of the full RCT in order to determine the future appropriate sample size. ETHICS AND DISSEMINATION: Ethical approval has been obtained by the Research Ethics Board of the Sainte-Justine University Hospital. The findings will be disseminated in peer-reviewed journals and conferences and presented to the Canadian paediatric grand round meetings. TRIAL REGISTRATION NUMBER: NCT05997680.

Long-term consequences of neonatal encephalopathy in the hypothermia era: protocol for a follow-up cohort study at 9 years of age.

INTRODUCTION: Therapeutic hypothermia (TH) became the standard of care treatment for neonates with moderate and severe neonatal encephalopathy (NE) in most industrialized countries about 10 years ago. Although TH is effective in reducing mortality and the incidence of severe developmental disabilities, the recent literature converges in reporting frequent cognitive and behavioural difficulties at school entry in children with NE-TH. Although these challenges are deemed minor compared with cerebral palsy and intellectual disability, their impacts on a child's self-determination and family's well-being are quite significant. Therefore, the nature and extent of these difficulties need to be comprehensively described so that appropriate care can be offered. METHODS AND ANALYSIS: The current study will be the largest follow-up study of neonates with NE treated with TH to characterize their developmental outcomes and associated brain structural profiles at 9 years of age. Specifically, we will compare executive function, attention, social cognition, behaviour, anxiety, self-esteem, peer problems, brain volume, cortical features, white matter microstructure and myelination between children with NE-TH and matched peers without NE. Associations of perinatal risk factors and structural brain integrity with cognitive, behavioural and psycho-emotional deficits will be evaluated to inform about the potential aggravating and protective factors associated with function. ETHICS AND DISSEMINATION: This study is supported by the Canadian Institute of Health Research (202203PJT-480065-CHI-CFAC-168509), and received approval from the Pediatric Ethical Review Board of the McGill University Health Center (MP-37-2023-9320). The study findings will be disseminated in scientific journals and conferences and presented to parental associations and healthcare providers to inform best practices. TRIAL REGISTRATION NUMBER: NCT05756296.

Associations between neurological examination at term-equivalent age and cerebral hemodynamics and oxygen metabolism in infants born preterm.

Background: Infants born at 29-36 weeks gestational age (GA) are at risk of experiencing neurodevelopmental challenges. We hypothesize that cerebral hemodynamics and oxygen metabolism measured by bedside optical brain monitoring are potential biomarkers of brain development and are associated with neurological examination at term-equivalent age (TEA). Methods: Preterm infants (N = 133) born 29-36 weeks GA and admitted in the neonatal intensive care unit were enrolled in this prospective cohort study. Combined frequency-domain near infrared spectroscopy (FDNIRS) and diffuse correlation spectroscopy (DCS) were used from birth to TEA to measure cerebral hemoglobin oxygen saturation and an index of microvascular cerebral blood flow (CBF i ) along with peripheral arterial oxygen saturation (SpO2). In combination with hemoglobin concentration in the blood, these parameters were used to derive cerebral oxygen extraction fraction (OEF) and an index of cerebral oxygen metabolism (CMRO2i ). The Amiel-Tison and Gosselin Neurological Assessment was performed at TEA. Linear regression models were used to assess the associations between changes in FDNIRS-DCS parameters from birth to TEA and GA at birth. Logistic regression models were used to assess the associations between changes in FDNIRS-DCS parameters from birth to TEA and neurological examination at TEA. Results: Steeper increases in CBF i (p < 0.0001) and CMRO2i (p = 0.0003) were associated with higher GA at birth. Changes in OEF, CBF i , and CMRO2i from birth to TEA were not associated with neurological examination at TEA. Conclusion: In this population, cerebral FDNIRS-DCS parameters were not associated with neurological examination at TEA. Larger increases in CBF i and CMRO2i from birth to TEA were associated with higher GA. Non-invasive bedside FDNIRS-DCS monitoring provides cerebral hemodynamic and metabolic parameters that may complement neurological examination to assess brain development in preterm infants.

Social cognition and competence in preschoolers with congenital heart disease.

OBJECTIVE: Children born with congenital heart disease (CHD) are at an increased risk for various neurodevelopmental impairments. However, little is known regarding social outcomes associated with CHD, particularly during early childhood. The present study aimed to characterize the sociocognitive profile and to assess the contribution of language, executive functions (EF), and social cognition to social competence (SC) in preschoolers with CHD. METHOD: Five-year-old children with CHD (n = 55) completed a standardized neuropsychological assessment. Performance on sociocognitive skills was compared to test norms using one-sample t tests. Hierarchical regression was conducted to examine the associations between language skills, affect recognition (AR), theory of mind (ToM), EF (performance-based and parent-rated), and social competence. RESULTS: Children with CHD performed significantly worse than norms in language and ToM, whereas EF and social competence appeared generally preserved in our sample. In hierarchical regression analysis, cognitive functions (language score, AR, ToM, EF performance) accounted for a significant 24.3% of the variance. Parent-rated EF added another 24.8% to the total explained variance. CONCLUSIONS: These findings provide new evidence for understanding social cognition and competence among preschoolers with CHD, showing vulnerability in social cognition and language skills but not in social competence more generally. The model suggests a combined contribution of social cognition, language, and EF on social outcomes. Remedial programs addressing these intervention targets could be useful in promoting social development in this vulnerable population. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Utility of the Ages and Stages Questionnaires 3rd Edition for Developmental Screening in Children with Surgically Repaired Congenital Heart Disease.

Aim: This study sought to evaluate the accuracy of the Ages and Stages Questionnaires 3rd Edition (ASQ-3) in identifying developmental delay (DD) in children with congenital heart disease (CHD) born at term who underwent surgical repair.Methods: Participants had to complete ASQ-3 and Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) at 12 and 24 months. A child was considered at risk of DD for a ASQ-3 domain when he scored below the cutoff (≤-1SD or ≤-2SD). A child had a DD in a BSID-III domain when the score was ≤-1SD. The validity for each ASQ-3 domain and for overall ASQ-3 was measured.Results: At 12 months (n = 64), overall ASQ-3 (≤-2SD) sensitivity was 88%, specificity 74%. At 24 months (n = 82), overall ASQ-3 (≤-2SD) sensitivity was 74%, specificity 88%.Conclusion: The results support the utility of the ASQ-3 for screening the overall risk of DD in children with CHD.
