[PMID: 38195921 PMCID: PMC11161409 DOI: 10.1038/s41372-023-01852-9] [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: 08/02/2023] [Revised: 12/01/2023] [Accepted: 12/05/2023] [Indexed: 01/11/2024]
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.

Research gaps in the neurodevelopmental assessment of children with complex congenital heart defects: a scoping review. Front Pediatr 2024; 12:1340495. [PMID: 38846331 PMCID: PMC11155449 DOI: 10.3389/fped.2024.1340495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 04/15/2024] [Indexed: 06/09/2024] Open
Abstract
Background Children with congenital heart defects (CHD) are at risk for a range of developmental disabilities that challenge cognition, executive functioning, self-regulation, communication, social-emotional functioning, and motor skills. Ongoing developmental surveillance is therefore key to maximizing neurodevelopmental outcome opportunities. It is crucial that the measures used cover the spectrum of neurodevelopmental domains relevant to capturing possible predictors and malleable factors of child development. Objectives This work aimed to synthesize the literature on neurodevelopmental measures and the corresponding developmental domains assessed in children aged 1-8 years with complex CHD. Methods PubMed was searched for terms relating to psycho-social, cognitive and linguistic-communicative outcomes in children with CHD. 1,380 papers with a focus on complex CHD that reported neurodevelopmental assessments were identified; ultimately, data from 78 articles that used standardized neurodevelopmental assessment tools were extracted. Results Thirty-nine (50%) of these excluded children with syndromes, and 9 (12%) excluded children with disorders of intellectual development. 10% of the studies were longitudinal. The neurodevelopmental domains addressed by the methods used were: 53% cognition, 16% psychosocial functioning, 18% language/communication/speech production, and 13% motor development-associated constructs. Conclusions Data on social communication, expressive and receptive language, speech motor, and motor function are underrepresented. There is a lack of research into everyday use of language and into measures assessing language and communication early in life. Overall, longitudinal studies are required that include communication measures and their interrelations with other developmental domains.

Association between neurodevelopmental outcomes and concomitant presence of NEC and IVH in extremely low birth weight infants. J Perinatol 2024; 44:108-115. [PMID: 37735208 DOI: 10.1038/s41372-023-01780-8] [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: 03/09/2023] [Revised: 08/31/2023] [Accepted: 09/12/2023] [Indexed: 09/23/2023]
Abstract
OBJECTIVE To quantify the association between necrotizing enterocolitis (NEC) and neurodevelopmental disability (NDI) in extremely low birth weight (ELBW) infants with intraventricular hemorrhage (IVH). STUDY DESIGN ELBW survivors born 2011-2017 and evaluated at 16-26 months corrected age in the Vermont Oxford Network (VON) ELBW Follow-Up Project were included. Logistic regression determined the adjusted relative risk (aRR) of severe NDI in medical or surgical NEC compared to no NEC, stratified by severity of IVH. RESULTS Follow-up evaluation occurred in 5870 ELBW survivors. Compared to no NEC, medical NEC had no impact on NDI, regardless of IVH status. Surgical NEC increased risk of NDI in patients with no IVH (aRR 1.69; 95% CI 1.36-2.09), mild IVH (aRR 1.36;0.97-1.92), and severe IVH (aRR 1.35;1.13-1.60). CONCLUSIONS ELBW infants with surgical NEC carry increased risk of neurodevelopmental disability within each IVH severity stratum. These data describe the additive insult of surgical NEC and IVH on neurodevelopment, informing prognostic discussions and highlighting the need for preventative interventions.

Abstract
OBJECTIVES Extremely preterm babies have a significant risk of neurodevelopmental impairment (NDI). There has been little investigation regarding the impact of prematurity on families. The objective of this study was to explore parental perspectives regarding the impact of prematurity on themselves/their family. METHODS Over 1 year, parents of children born <29 weeks' gestational age (GA) who were between 18 months old and 7 years old and came for their follow-up visit were invited to participate. They were asked to categorise the impacts of prematurity on their life and their family as positive, negative or both and to describe those impacts in their own words. Thematic analysis was performed by a multidisciplinary group, including parents. Logistic regression was performed to compare parental responses. RESULTS Among parents (n=248, 98% participation rate), most (74%) reported that their child's prematurity had both positive and negative impacts on their life or their family's life, while 18% reported only positive impacts and 8% only negative impacts. These proportions were not correlated with GA, brain injury, nor level of NDI. The positive impacts reported included: an improved outlook on life, such as gratitude and perspective (48%), stronger family relationships (31%) and the gift of the child (28%). The negative themes were stress and fear (42%), loss of equilibrium due to medical fragility (35%) and concerns about developmental outcomes including the child's future (18%). CONCLUSION Parents report both positive and negative impacts after an extremely preterm birth, independent of disability. These balanced perspectives should be included in neonatal research, clinical care and provider education.

Karyadiguna N, Bernie C, Barnes EH, Williams K, Lo BH. Does pre-school developmental assessment agree with later intellectual assessment? A retrospective cohort study. J Paediatr Child Health 2023; 59:962-967.

Abstract
AIM This study sought to assess the association between early developmental assessment of toddlers with idiopathic global developmental delay (GDD) and their later intelligence test scores. METHODS Toddlers with idiopathic GDD attending a community clinic over a 6-year period were assessed initially using the Griffiths Mental Development Scales - Extended Revised version (GMDS-ER) and later completing formal intelligence testing using the Stanford-Binet Intelligence Scale - 5th Edition (SB5) at age 4-6 years. Spearman's correlation was used to assess the association of quotient scores across the tools. The composite quotient (GQ) and the subscale quotients of GMDS-ER were correlated with the full-scale IQ (FSIQ), verbal and non-verbal IQ scores from the SB5. RESULTS Thirty of 153 children assessed at the clinic were eligible for the study. The correlation between GMDS-ER GQ and later SB5 FSIQ was strong (r = 0.86, P < 0.001). The subscales' associations were moderate to strong (0.48-0.71). Eighty-six percent (86%) of children with delay on GMDS-ER GQ were found later to be in the impaired category based on the FSIQ of the SB5. CONCLUSION There was a strong association between toddlers' early developmental quotients and later IQ scores for children with idiopathic GDD, though agreement between early GDD diagnoses and later intellectual disability is not absolute. Individualised care is needed around prognostic advice and recommendations to caregivers and families in the early years, so they may effectively plan for interventions, supports and later reassessment to optimise their child's development and learning.

Prenatal exposure to ambient air pollution is associated with neurodevelopmental outcomes at 2 years of age. Environ Health 2023; 22:11.

Abstract
BACKGROUND Higher prenatal ambient air pollution exposure has been associated with impaired neurodevelopment in preschoolers and school-aged children. The purpose of this study was to explore the relationships between prenatal ambient air pollution exposure and neurodevelopment during infancy. METHODS This study examined 161 Latino mother-infant pairs from the Southern California Mother's Milk Study. Exposure assessments included prenatal nitrogen dioxide (NO2) and particulate matter smaller than 2.5 and 10 microns in diameter (PM2.5 and PM10, respectively). The pregnancy period was also examined as three windows, early, mid, and late, which describe the first, middle, and last three months of pregnancy. Infant neurodevelopmental outcomes at 2 years of age were measured using the Bayley-III Scales of Infant and Toddler Development. Multivariable linear models and distributed lag linear models (DLM) were used to examine relationships between prenatal exposures and neurodevelopmental scores, adjusting for socioeconomic status, breastfeeding frequency, time of delivery, pre-pregnancy body mass index, and infant birthweight and sex. RESULTS Higher prenatal exposure to PM10 and PM2.5 was negatively associated with composite cognitive score (β = -2.01 [-3.89, -0.13] and β = -1.97 [-3.83, -0.10], respectively). In addition, higher average prenatal exposure to PM10 was negatively associated with composite motor (β = -2.35 [-3.95, -0.74]), scaled motor (β = -0.77 [-1.30, -0.24]), gross motor (β = -0.37 [-0.70, -0.04]), fine motor (β = -0.40 [-0.71, -0.09]), composite language (β = -1.87 [-3.52, -0.22]), scaled language (β = -0.61 [-1.18, -0.05]) and expressive communication scaled scores (β = -0.36 [-0.66, -0.05]). DLMs showed that higher prenatal air pollution exposure during mid and late pregnancy was inversely associated with motor, cognitive, and communication language scores. CONCLUSIONS Higher exposure to air pollutants during pregnancy, particularly in the mid and late prenatal periods, was inversely associated with scaled and composite motor, cognitive, and language scores at 2 years. These results indicate that prenatal ambient air pollution may negatively impact neurodevelopment in early life.

Abstract
OBJECTIVE To evaluate effect of enteral zinc supplementation on growth and neurodevelopmental outcomes of preterm infants. STUDY DESIGN A systematic review and meta-analysis of randomized-controlled trials (RCTs) examining growth and neurodevelopmental outcomes after zinc supplementation in preterm infants. RESULTS Of eight RCTs involving 742 infants included, seven reported growth anthropometrics at 3-6 months corrected age (CA) and two reported neurodevelopmental outcomes at 6-12 months CA. Zinc supplementation was associated with increased weight z-score (weighted mean difference (WMD) = 0.50; 95% CI 0.23-0.76, heterogeneity I2 = 89.1%; P < 0.01), length z-score (WMD = 1.12; 95% CI 0.63-1.61, heterogeneity I2 = 96.0%; P < 0.01) and motor developmental score (WMD = 9.54; 95% CI 6.6-12.4 heterogeneity I2 = 0%; P = 0.52). There was no effect on head circumference and total developmental score. Evidence is "moderate" certainty for weight and length and "very low" certainty for neurodevelopment. CONCLUSION Zinc supplementation may enhance weight gain and linear growth in preterm infants. There is a lack of data about relationship between zinc supplementation and neurodevelopment.

Diffusion Tensor Imaging Changes Do Not Affect Long-Term Neurodevelopment following Early Erythropoietin among Extremely Preterm Infants in the Preterm Erythropoietin Neuroprotection Trial. Brain Sci 2021; 11:brainsci11101360.

Abstract
We aimed to evaluate diffusion tensor imaging (DTI) in infants born extremely preterm, to determine the effect of erythropoietin (Epo) on DTI, and to correlate DTI with neurodevelopmental outcomes at 2 years of age for infants in the Preterm Erythropoietin Neuroprotection (PENUT) Trial. Infants who underwent MRI with DTI at 36 weeks postmenstrual age were included. Neurodevelopmental outcomes were evaluated by Bayley Scales of Infant and Toddler Development (BSID-III). Generalized linear models were used to assess the association between DTI parameters and treatment group, and then with neurodevelopmental outcomes. A total of 101 placebo- and 93 Epo-treated infants underwent MRI. DTI white matter mean diffusivity (MD) was lower in placebo- compared to Epo-treated infants in the cingulate and occipital regions, and occipital white matter fractional isotropy (FA) was lower in infants born at 24-25 weeks vs. 26-27 weeks. These values were not associated with lower BSID-III scores. Certain decreases in clustering coefficients tended to have lower BSID-III scores. Consistent with the PENUT Trial findings, there was no effect on long-term neurodevelopment in Epo-treated infants even in the presence of microstructural changes identified by DTI.
