Survival of infants born extremely preterm (EP) (<28 weeks' gestation) has increased since the early 1990s. It is necessary to know whether survival accompanied by neurodevelopmental disability.To examine changes in major (ie, moderate or severe) disability and free at 2 years EP.Four prospective longitudinal cohort studies comprising all EP live births 22 27 gestation from April 1, 2016, March 31, 2017, earlier eras (1991-1992, 1997, 2005), contemporaneous term-born controls state Victoria,...

OBJECTIVES: The objective of this study was to describe language functioning at 13 years age and examine its developmental trajectory from 2 in children born very preterm (VP) compared with term controls. METHODS: Two hundred twenty-four VP (&amp;lt;30 weeks’ gestation) 77 controls had skills assessed by using performance-based and/or parent-report measures 2, 5, 7, age. Regression models were used compare verbal memory, grammar, semantics, pragmatic between the groups Linear mixed effects...

This study investigated the digital version of Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) Coding subtest in a large Australian clinical and non-clinical sample 6–11 year old children (N = 794). Data was retrospectively pooled from several studies. Results showed scaled score significantly elevated compared with all other subtests (M difference 2.01, 95% CI. 1.74–2.27). Overall FSIQ higher when calculated using Symbol Search 2.067, 1.79–2.34). The discrepancy...

The relationship between attention and visual masking was investigated in a cued detection task using factorial manipulation. Stimuli were either unmasked, or masked with simultaneous (integration) masks, delayed (interruption) integration-interruption mask pairs. cuing effects sensitivity smallest unmasked stimuli, intermediate single largest Large RT found all stimulus conditions. results are inconsistent general mechanisms of contrast gain response gain, which do not predict interactions...

Importance Although children born moderate to late preterm (MLP; 32-36 weeks’ gestation) have more neurodevelopmental problems compared with early term or later (≥37 gestation), detailed understanding of affected domains at school age is lacking. Little known risk factors for poorer development. Objective To examine whether being MLP associated outcomes 9 years and describe neurodevelopment in MLP. Design, Setting, Participants This prospective, longitudinal cohort study recruited healthy...

Abstract Objectives: Preterm children demonstrate deficits in executive functions including inhibition, working memory, and cognitive flexibility; however, their goal setting abilities (planning, organization, strategic reasoning) remain unclear. This study compared between very preterm (VP: &lt;30 weeks/&lt;1250 grams) term born controls during late childhood. Additionally, early risk factors (neonatal brain abnormalities, medical complications, sex) were examined relationship to outcomes...

Attention deficits are common in children born very preterm (VP), especially for with higher social risk. The aim of this study was to examine the association between parenting behavior and attention VP, whether is influenced by familial Two hundred twenty-four <30 weeks’ gestation and/or a birth weight <1250 g were recruited at birth. At 2 years, risk calculated behaviors observed during parent-child interaction task, children’s skills assessed 7 13 years using standardized assessments....
