Childhood exposures to environmental chemicals and neurodevelopmental outcomes in congenital heart disease.

ABSTRACT:

Background

Children with congenital heart defects have an increased risk of neurodevelopmental disability. The impact of environmental chemical exposures during daily life on neurodevelopmental outcomes in toddlers with congenital heart defects is unknown.

Methods

This prospective study investigated the impacts of early childhood exposure to mixtures of environmental chemicals on neurodevelopmental outcomes after cardiac surgery. Outcomes were assessed at 18 months of age using The Bayley Scales of Infant and Toddler Development-III. Urinary concentrations of exposure biomarkers of pesticides, phenols, parabens, and phthalates, and blood levels of lead, mercury, and nicotine were measured at the same time point. Bayesian profile regression and weighted quantile sum regression were utilized to assess associations between mixtures of biomarkers and neurodevelopmental scores.

Results

One-hundred and forty infants were enrolled, and 110 (79%) returned at 18 months of age. Six biomarker exposure clusters were identified from the Bayesian profile regression analysis; and the pattern was driven by 15 of the 30 biomarkers, most notably 13 phthalate biomarkers. Children in the highest exposure cluster had significantly lower adjusted language scores by -9.41 points (95%CI: -17.2, -1.7) and adjusted motor scores by -4.9 points (-9.5, -0.4) compared to the lowest exposure. Weighted quantile sum regression modeling for the overall exposure-response relationship showed a significantly lower adjusted motor score (β = -2.8 points [2.5th and 97.5th percentile: -6.0, -0.6]). The weighted quantile sum regression index weights for several phthalates, one paraben, and one phenol suggest their relevance for poorer neurodevelopmental outcomes.

Conclusions

Like other children, infants with congenital heart defects are exposed to complex mixtures of environmental chemicals in daily life. Higher exposure biomarker concentrations were associated with significantly worse performance for language and motor skills in this population.

Project description:ImportanceA recent advisory from the American Heart Association delineated the potential benefits of developmental care for hospitalized children with congenital heart disease (CHD) and a critical gap in research evaluating the association of such inpatient programs with neurodevelopmental outcomes.ObjectiveTo investigate associations between the Cardiac Inpatient Neurodevelopmental Care Optimization (CINCO) program interventions, delirium, and neurodevelopment in young children (newborn through age 2 years) hospitalized with CHD.Design, setting, and participantsThis cohort study used quality improvement data from inpatient cardiac units at a tertiary care children's hospital in the US. Participants were children aged 0 to 2 years who were admitted for at least 7 days from September 1, 2018, to September 1, 2023. The CINCO program was implemented on September 1, 2020, in 6-month plan-do-study-act phases.ExposuresThe 5 CINCO interventions were medical and/or nursing order panels, developmental kits, bedside developmental plans, caregiver mental health support handouts, and developmental care rounds.Main outcomes and measuresNumber of days with delirium per patient, which was measured using the Cornell Assessment of Pediatric Delirium (a score higher than 9 indicated delirium). Neurodevelopment was measured using the Bayley Scales of Infant and Toddler Development, Fourth Edition (BSID-4).ResultsThe full sample included 1331 qualifying admissions for 1019 unique pediatric patients (median [range] age at admission, 3.65 [0-34.62] months; 771 males [57.9%]), with a subcohort of 121 unique patients (median [range] age at admission, 0.00 [0-9.85] months; 77 males [63.6%]) whose initial hospitalization occurred before age 10 months and who underwent BSID-4 evaluation at age 12 months or older. The mean (SD) number of days with delirium per patient was stable for 2 years prior to CINCO implementation, decreased by 54.0% between phases 1 and 2 of the CINCO program (from 3.05 [0.60] to 1.38 [0.21]), and then remained stable over time. Each of the 5 CINCO interventions was associated with lower delirium after false discovery rate (FDR) correction (eg, medical and/or nursing order panel: B = -1.376 [95% CI, -1.767 to -0.986]; F2,1273 = 47.767; partial η2 = 0.036; P < .001). Mean (SD) BSID-4 cognitive index scores were stable for 2 years prior to implementation, higher between phases 1 and 2 of the program (from 81.67 [14.14] to 93.92 [19.43]), and then remained stable over time. Four of the 5 interventions were associated with higher BSID-4 cognitive scores after FDR correction (eg, bedside developmental plans: B = 8.585 [95% CI, 2.247-14.923]; F5, 101 = 7.221; partial η2 = 0.067; P = .008). Delirium was associated with lower BSID-4 cognitive scores. There were no associations between delirium and BSID-4 language or motor scores.Conclusions and relevanceThis cohort study found that among hospitalized children with CHD, the implementation of an inpatient developmental care program was associated with reduced incidence of delirium and higher cognitive scores. Pediatric cardiac centers may consider adopting these low-cost, low-risk, generalizable program interventions.

Project description:BackgroundNeurodevelopmental disability is a common long-term concern following surgery for congenital heart disease (CHD). Little information is available from low-resource environments where the majority of children with CHD are born. Several challenges in the CHD care continuum exist in such environments.MethodsWe followed 1346 infants who were operated for CHD using cardiopulmonary bypass from five paediatric cardiac programmes across India. The neurodevelopmental assessment was done using the Developmental Assessment Scale for Indian Infants (DASII) at 6 months after surgery.ResultsA total of 1145 (94.8%) infants were alive at 6 months and 127 (11.1%) were lost to follow-up. The mean age of participants at baseline was 5.2 (3.6) months. The mean motor developmental quotient (DMoQ) and mental developmental quotient (DMeQ) of the remaining 1018 infants were 81.8 (69.5, 93.0) and 87.7 (77.1, 95.7), respectively. A total of 262 (25.7%) infants had motor developmental delay and 157 (15.4%) had mental developmental delay. Syndromic association, younger age at surgery, duration of mechanical ventilation and head circumference were significantly associated with DMoQ. The DMeQ was associated with syndromes, duration of hospital and intensive care unit stay and socioeconomic status. The preoperative condition did not impact mental and motor development. Motor clusters with maximum delay included body control and locomotion. Mental clusters with maximum delay included reaching and manipulation, social interaction-imitative behaviour and vocabulary comprehension.ConclusionsSurvivors of infant heart surgery experience significant motor and mental neurodevelopmental delay. This delay is associated with similar factors reported by earlier studies. As more high-risk infants undergo cardiac surgery in low-resource settings, a growing population will require significant societal resources for neurodevelopmental assessment as well as neurodevelopmental rehabilitation. These resources include trained personnel for comprehensive developmental assessment of survivors of CHD surgery, as well as infrastructural requirements for dedicated assessment rooms in centres providing surgical care for CHD patients.
