Predictors of language and reading outcomes in 12-year-old children born very preterm.

Aim: To investigate predictors of language and reading outcomes in 12-year-old Swedish children born very preterm (<32 gestational weeks) in 2004-2007.

Method: Children born very preterm (n = 78, 43 girls), and term-born controls (n = 50, 32 girls), were examined on verbal IQ, semantic and phonemic fluency, sentence recall, reading fluency, word and phonological decoding at 12 years of age. The results were related to neonatal characteristics, language development, measured with Bayley-III, at 2.

Mri findings, looking behaviour and affect recognition in very preterm children: A pilot study.

Children born very preterm often exhibit atypical gaze behaviors, affect recognition difficulties and are at risk for cerebral white matter damage. This study explored links between these sequalae. In 24 12-year-old children born very preterm, ventricle size using Evans and posterior ventricle indices, and corpus callosum area were used to measure white matter thickness.

Neurobehavioral symptoms in children born extremely preterm: A Swedish National Study.

Aim: To determine the prevalence of neurobehavioral symptoms at 6.5 years in children born extremely preterm (EPT, <27 weeks' gestation).

Methods: Population-based cohort study of infants born EPT in Sweden from 2004 to 2007.

Different aspects of visual perception are important for 12-year social functioning depending on gestational age.

Aim: Perceptual mechanisms in social functioning might promote interventions. We investigated relations between visual perception and social functioning, in preterm children.

Methods: A prospective preterm cohort born in Uppsala County, Sweden, in 2004-2007 and 49 full-term controls were examined at 12 years.

Predictive value of Bayley-III Motor Index for later motor difficulties in children born extremely preterm.

Aim: To investigate the predictive ability of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) Motor Index, in children born extremely preterm (<27 gestational weeks) without cerebral palsy.

Methods: Children from the EXPRESS study (all extremely preterm births in Sweden, 2004-2007) without neurosensory impairments assessed with Bayley-III at 2.5 years corrected age and Movement Assessment Battery for Children, Second Edition (MABC-2), at 6.

Early Hyperglycemia in Very Preterm Infants Is Associated with Reduced White Matter Volume and Worse Cognitive and Motor Outcomes at 2.5 Years.

Introduction: Hyperglycemia in very preterm infants is associated with increased morbidity and mortality. We aimed to investigate potential associations between early hyperglycemia, neonatal cerebral magnetic resonance imaging (MRI), and neurodevelopment at 2.5 years.

Visual tracking at 4 months in preterm infants predicts 6.5-year cognition and attention.

Background: Visual tracking of moving objects requires sustained attention and prediction of the object's trajectory. We tested the hypothesis that measures of eye-head tracking of moving objects are associated to long-term neurodevelopment in very preterm infants.

Methods: Visual tracking performance was assessed at 4 month's corrected age in 57 infants with gestational age <32 weeks.

Cognitive profiles of extremely preterm children: Full-Scale IQ hides strengths and weaknesses.

Aim: To study whether a specific cognitive profile can be identified for children born extremely preterm (EPT) by investigating: 1) strengths and weaknesses not revealed by Full-Scale IQ, 2) overlap between different cognitive deficits and 3) proportion of EPT children with multiple deficits.

Methods: We analysed data from the 4 version of Wechsler Intelligence Scales for Children in EPT children (n = 359) and matched controls (n = 367), collected within the 6.5-year follow-up of a population-based prospective cohort study.

Average 2.5-year neurodevelopmental test results in children born very preterm did not rule out cognitive deficits at 6.5 years of age.

Aim: The aim of the study was to investigate cognitive outcomes at 6.5 years in children born very preterm, in relation to neonatal characteristics and 2.5-year neurodevelopment.

Structured Observation of Motor Performance in Infants: Level and quality associated with later motor development.

Aim: The aim of this study was to investigate the level of motor development and the quality of motor performance during the first 10 months in relation to the Bayley Scales of Infant Development-third edition (Bayley-III) motor index at 2.5 years.

Methods: Children born very preterm from a population-based study (n = 113) were assessed with the Structured Observation of Motor Performance in Infants (SOMP-I) at 2, 4, 6 and 10 months corrected age and the Bayley-III motor index at 2.

Reaching skills of infants born very preterm predict neurodevelopment at 2.5 years.

The purpose was to investigate associations between quality of reaching for moving objects at 8 months corrected age and neurodevelopment at 2.5 years in children born very preterm (gestational age (GA), 24-31 weeks). Thirtysix infants were assessed while reaching for moving objects.

Visual tracking in very preterm infants at 4 mo predicts neurodevelopment at 3 y of age.

Background: Typically developing infants track moving objects with eye and head movements in a smooth and predictive way at 4 mo of age, but this ability is delayed in very preterm infants. We hypothesized that visual tracking ability in very preterm infants predicts later neurodevelopment.

Method: In 67 very preterm infants (gestational age<32 wk), eye and head movements were assessed at 4 mo corrected age while the infant tracked a moving object.
