Brief Summary

Prematurely born children are at higher risk of cognitive impairments and behavioral disorders than full-term children. There is growing evidence of significant volumetric and shape abnormalities in subcortical structures of premature neonates, which may be associated to negative long-term neurodevelopmental outcomes. The general objective is to look directly at the long-term neurodevelopmental implications of these neonatal subcortical structures abnormalities. Investigators propose to develop biomarkers of prematurity by comparing the morphological and diffusion properties of subcortical structures between preterm, with and without associated brain injuries, and full-term neonates using brain MRI. By combining subcortical morphological and diffusion properties, investigators hypothesize to be able to: (1) delineate specific correlative relationships between structures regionally and differentially affected by normal maturation and different patterns of white matter injury, and (2) improve the specificity of neuroimaging to predict neurodevelopmental outcomes earlier. The specific aims and general methodology are: 1) Build a new toolbox for neonatal subcortical structures analyses that combine a group lasso-based analysis of significant regions of shape changes, a structural correlation network analysis, a neonatal tractography, and tensor-based analysis on tracts; 2) Ascertain biomarkers of prematurity in neonates with different patterns of abnormalities using correlational and connectivity analysis within and between structures features; 3) Assess the predictive potential of subcortical imaging on neurodevelopmental outcomes by correlating neonatal imaging results with long-term neurodevelopmental scores at 9 and 18 months, and 6-8 years, follow-up. In each of these aims, investigators will use advanced neuroimaging analysis developed by their group and collaborator, including multivariate tensor-based morphometry and multivariate tract-based analysis. This application will provide the first complete subcortical network analysis in both term and preterm neonates. In the first study of its kind for prematurity, investigators will use sparse and multi-task learning to determine which of the biomarkers of prematurity at birth are the best predictors of long-term outcome. Once implemented, these methods will be available to compare subcortical structures for other pathologies in newborns and children.

Outcome Measures

Primary Outcomes (3)

  • Changes in Surface Area and Thickness of Subcortical Structures

    Measured in Voxel Size (mm)

    2018 - 2022

  • Changes in Diffusion values of white matter Tracts

    Measured in mm squared per second

    2018 - 2022

  • Differences in developmental Quotient / Neuropsychological scores

    Measured using standardized tests (Bayley-III and NIH toolbox)

    2018 - 2022

Study Arms (4)

Infant Control Group

The control arm (term born Infants) will receive an MRI at neonatal age and neurodevelopmental follow-up assessments, investigators will then compare significant morphological and diffusion properties within the brain to those of a Preterm brain.

Diagnostic Test: MRIDiagnostic Test: Neurodevelopmental/Neuropsychological Assessment

Infant Preterm Group

The experimental group will consist of preterm infants, who will receive an MRI at neonatal age and neurodevelopmental assessments. This groups scans will then be compared to those of the control arm. Significant biomarkers will then be identified.

Diagnostic Test: MRIDiagnostic Test: Neurodevelopmental/Neuropsychological Assessment

Childhood Control Group

The experimental group will consist of preterm born children aged 6-8 years, who received an MRI at neonatal age and will be called back for a neuropsychological assessment. This groups scans will then be compared to those of the children control arm. Significant biomarkers will then be identified.

Diagnostic Test: Neurodevelopmental/Neuropsychological Assessment

Childhood Preterm Group

The experimental group will consist of term born children aged 6-8 years, who received an MRI at neonatal age and will be called back for a neuropsychological assessment. This groups scans will then be compared to those of the children preterm group. Significant biomarkers will then be identified.

Sampling MethodNon-Probability Sample
Study Population

Our MRI data will consist of two separate neonatal cohorts. Cohort 1 is an existing dataset of neonates scanned in Pittsburgh as part of a separate completed grant. This cohort was scanned at neonatal equivalent age and will be brought back for childhood neurodevelopmental outcomes at 6-8 years of age. Cohort 2 will be a new prospectively recruited cohort that will be scanned in Los Angeles as part of this proposal and will be brought back for infant neurodevelopmental outcome at 9 and 18 months.
