Motor impairment in very preterm-born children

BACKGROUND: The objective of this study was to examine how nonverbal skills at age five years relate to visual perception and brain activation during visual perception tasks at age 12 years in very preterm subjects without visual or other neurodevelopmental impairments or major brain pathologies. METHODS: At age five years, 36 prematurely born (birth weight ≤1500 g or gestational age less than 32 weeks) and 31 term-born control children were assessed with the nonverbal subtests of the Wechsler Preschool and Primary Scale of Intelligence-Revised and the NEPSY-Second Edition...

We reviewed literature on long-term motor outcomes of individuals aged five years or older born very preterm (VP: ≤32 weeks of gestation) or with very low birth weight (VLBW: ≤1500g), without cerebral palsy (CP). PubMed produced 2827 articles, whereof 38 were eligible. Assessed by standardised and norm-based motor tests, the Movement Assessment Battery for Children being the most widely used, VP/VLBW individuals showed poorer motor skills compared with term-born controls with differences of approximately 1 SD in magnitude...

OBJECTIVES: To determine, in children born preterm, the association of mechanical ventilation duration with brainstem development, white matter maturation, and neurodevelopmental outcomes at preschool age. STUDY DESIGN: This prospective cohort study included 144 neonates born at <30 weeks of gestation (75 male, mean gestational age 27.1 weeks, SD 1.6) with regional brainstem volumes automatically segmented on magnetic resonance imaging at term-equivalent age (TEA)...

INTRODUCTION: Infants born very preterm are at risk of adverse neurodevelopmental outcomes, including cognitive deficits, motor impairments and cerebral palsy. Earlier identification enables targeted early interventions to be implemented with the aim of improving outcomes. METHODS AND ANALYSIS: Protocol for 6-year follow-up of two cohorts of infants born <31 weeks gestational age (PPREMO: Prediction of Preterm Motor Outcomes; PREBO: Prediction of Preterm Brain Outcomes) and a small term-born reference sample in Brisbane, Australia...

Cognitive and neurobehavioral problems are among the most severe adverse outcomes in very preterm infants. Such neurodevelopmental impairments may be mitigated through nonpharmacological interventions such as creative music therapy (CMT), an interactive, resource- and needs-oriented approach that provides individual social contact and musical stimulation. The aim was to test the feasibility of a study investigating the role of CMT and to measure the short- and medium-term effects of CMT on structural and functional brain connectivity with MRI...

BACKGROUND: Nutritional supplements may improve development of infants born small (preterm or small for gestational age [SGA]) but may increase the risk of later metabolic disease. We conducted a systematic review and meta-analysis to assess the effects of macronutrient supplements for infants born small on later development and metabolism. METHODS AND FINDINGS: We searched OvidMedline, Embase, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews from inception to April 1, 2019, and controlled-trials...

AIM: Very preterm children born less than 32 weeks of gestation are at risk for motor difficulties such as cerebral palsy and developmental coordination disorder. This study explores the association between diffusion tensor imaging metrics at term and motor outcomes at 11 years of age. METHODS: A cohort of 37 very preterm infants (mean gestational age 29 4/7, SD 2 0/7) born in 2004-2006 in Turku University Hospital underwent diffusion tensor imaging at term. A region-of-interest analysis of fractional anisotropy and mean diffusivity was performed...

BACKGROUND: Altered basal ganglia and thalamic connectivity may be critical for cognitive, motor and behavioural impairments common to very preterm (<32 weeks' gestational age) children. AIMS: To (1) compare corticostriatal and thalamocortical tract connectivity between very preterm and term-born children at 7 years of age; (2) explore tract connectivity associations with 7-year neurodevelopmental outcomes, and whether these relationships differed between groups...

OBJECTIVES: The aim of this study was to determine whether a new nutrition protocol designed to increase early protein intakes while reducing fluid volume in infants born very preterm was associated with altered neurodevelopment and growth in childhood. METHODS: A retrospective, observational cohort study of children born <30 weeks' gestation or <1500 g and admitted to the neonatal unit, National Women's Hospital, Auckland, New Zealand, before and after a change in nutrition protocol...

Preterm infants are at high risk for brain injury during the perinatal period. Intraventricular hemorrhage and periventricular leukomalacia, the two most common patterns of brain injury in prematurely-born children, are associated with poor neurodevelopmental outcomes. The hippocampus is known to be critical for learning and memory; however, it remains unknown how these forms of brain injury affect hippocampal growth and how the resulting alterations in hippocampal development relate to childhood outcomes. To investigate these relationships, hippocampal segmentations were performed on term equivalent MRI scans from 55 full-term infants, 85 very preterm infants (born ≤32 weeks gestation) with no to mild brain injury and 73 very preterm infants with brain injury (e...

BACKGROUND: Children born very preterm are at risk for cognitive deficits and motor impairment. Enhanced protein intake immediately after very preterm birth has been associated with favorable growth and improved neurodevelopment. It is unknown whether increased protein intake after discharge from the hospital affects long-term neurodevelopment. OBJECTIVE: The primary objective was to assess neurodevelopment from infancy to 8 years in preterm-born children who received either protein-enriched formula (PDF), standard term formula (TF), or human milk (HM) after discharge...

BACKGROUND: The Bayley Scales of Infant and Toddler Development, third edition (Bayley-III) are widely used to assess the development of children born preterm. However, it is still unclear whether US norms are adequate for use in other populations. In 2014, the German version of the Bayley-III with German norms was published. OBJECTIVES: We aimed to compare the performance of very-preterm infants at one, two, and three years of age using the German versus US norms of the Bayley-III...

BACKGROUND: Developmental Coordination Disorder (DCD) is a neurodevelopmental disorder that involves difficulties in goal-directed motor coordination, with ineffective control of fine and gross motor movements in the absence of sensory impairment or neurological condition. DCD is frequently reported in children born very preterm (VP) who survive without CP. AIMS: To measure the risk of DCD at school age in a large area-based cohort of VP children and general population controls, adjusting for gender, birth weight by gestational age and age at assessment...

OBJECTIVE: The objective of this study is to explore developmental outcomes at five years after early-onset fetal growth restriction (FGR). STUDY DESIGN: Retrospective data analysis of prospective follow-up of patients of three Dutch centres, who participated in a twenty centre European randomized controlled trial on timing of delivery in early-onset FGR. Developmental outcome of very preterm infants born after extreme FGR is assessed at (corrected) age of five...

BACKGROUND: Surviving preterm born children, postnatally exposed to high doses of dexamethasone, show an increased risk of neurodevelopmental impairments. Regarding treatment with low doses of dexamethasone, no data exist on outcomes at school age. AIM: To assess the functional outcome at school age of preterm-born children treated with low-dose dexamethasone. STUDY DESIGN: In this cohort study, twenty-seven very preterm-born infants treated with dexamethasone from eight days after birth, underwent neuropsychological assessments at age 6-13 years...

Background: Children born very preterm (PT) after fetal growth restriction (FGR) exhibit cognitive impairment at early school age. The relationship between neurodevelopmental impairment and attained regional brain volumes is unknown. Methods: We studied 23 preterm children with FGR (PT-FGR), 24 matched preterm children AGA (PT-AGA), and 27 matched term AGA children (T-AGA) by measuring brain volumes with magnetic resonance imaging at early school age. Cognitive and motor functions were assessed by the Wechsler Intelligence Scales for Children and the ABC-Movement score...

Individuals born very preterm (<32 weeks gestation) are at increased risk for neuromotor impairments. The ability to characterize the structural and functional mechanisms underlying these impairments remains limited using existing neuroimaging techniques. Resting state-functional magnetic resonance imaging (rs-fMRI) holds promise for defining the functional network architecture of the developing brain in relation to typical and aberrant neurodevelopment. In 58 very preterm and 65 term-born children studied from birth to age 12 years, we examined relations between functional connectivity measures from low-motion rs-fMRI data and motor skills assessed using the Movement Assessment Battery for Children, 2nd edition...

Aim of our study was assessment of developmental outcome of neonates with respiratory distress syndrome, evaluation of the impact of RDS on child's health, growth and neurodevelopment at 2 years of age. Case control study included 138 children, from those, 74 preterm (gestational age 32-36 weeks), who were divided into 2 study groups: I groups - involved 38 preterm with RDS and II group - 36 preterm patients without RDS and other neonatal problems. Control group included 42 patients born term with uncomplicated history...

Background: The World Health Organization's International Classification of Functioning, Disability, and Health framework, Children and Youth Version (ICF-CY), provides a valuable method of conceptualizing the multidomain difficulties experienced by children born very preterm (VP). Reviews investigating motor outcomes at preschool age across ICF-CY domains are lacking. Purpose: The purpose of this review is to identify and compare motor outcomes of 3- to 6-year-old children born VP and children born full-term (FT) within the ICF-CY framework...
