Social-emotional delays at 2 years in extremely low gestational age survivors: correlates of impaired orientation/engagement and emotional regulation.

Background: Premature infants are less socially and emotionally competent at school age than infants born at term.

Aims: To evaluate the correlates of social and emotional delays at 2 years of age among prematurely born children.

Study Design: This is a prospective cohort study.

Neonatal cranial ultrasound lesions and developmental delays at 2 years of age among extremely low gestational age children.

Background: Studies of the relationship between ultrasound images from preterm newborns and developmental delay most often are based on small samples defined by birth weight and exclude infants not testable with standardized assessments.

Methods: We evaluated associations between ultrasound-defined lesions of the brain and developmental delays at 24 months' corrected age in 1017 children born before the 28th postmenstrual week. Brain ultrasound scans were read for concordance on 4 lesions: intraventricular hemorrhage, moderate/severe ventriculomegaly, white matter echodense/hyperechoic lesions, and white matter echodense/hypoechoic lesions and 2 diagnoses-periventricular leukomalacia and periventricular hemorrhagic infarction.
