CONTEXT: Late-preterm infants (LPIs) born at 34 to 36 weeks' gestation are increasingly regarded as being at risk for adverse developmental outcomes. To date, the early childhood development of LPIs has not been systematically considered. OBJECTIVE: To undertake a broad examination of literature relating to early childhood development at the ages of 1 to 7 years of LPIs born at 34 to 36 weeks' gestation. METHODS: We conducted a systematic review of early childhood outcomes in LPIs by using 9 electronic databases (January 1980 to March 2010). Bibliographies were reviewed. After examination of abstracts, ineligible studies were excluded. A specifically designed data-extraction form was used. The methodologic quality of included studies was assessed by using well-documented quality-appraisal guidelines. RESULTS: Of 4581 studies, 10 (3 prospective and 7 retrospective cohort) were included. Studies were heterogeneous, and poorer outcomes were reported among LPIs in relation to neurodevelopmental disabilities, educational ability, early-intervention requirements, medical disabilities, and physical growth in comparison to term-born children. No identified study used healthy nonadmitted LPIs as a comparison group for admitted LPIs. CONCLUSIONS: Evidence suggests that LPIs are at increased risk of adverse developmental outcomes and academic difficulties up to 7 years of age in comparison to term infants. An infant control group matched for gestational age has not been used; thus, for LPIs, the effect of neonatal admission on longer-term outcomes has not been fully explored. Systematic measurement of early childhood outcomes is lacking, and focused long-term follow-up studies are needed to investigate early childhood development after late-preterm birth.

OBJECTIVE: To examine the association between child maltreatment (abuse and neglect) and long-term cognitive outcomes within a prospective birth cohort. METHODS: A birth cohort of 7223 children was recruited. Independent reports of suspected child maltreatment were confidentially linked to the longitudinal study database. The principal predictor variable was notification to the state child-protection authority for suspected maltreatment (abuse, neglect, or both). The outcome variables were scores on the Wide Range Achievement Test (WRAT) reading test and Raven's Standard Progressive Matrices (RSPM), completed at 14 years of age. Multivariate regression analysis was used to adjust for potential confounders. RESULTS: A total of 3796 subjects completed either the WRAT or RSPM. There was a higher loss to follow-up among children who had been reported to the state as suspected victims of maltreatment. After controlling for a range of possible confounders and modifiers, notification to the state for child maltreatment (abuse, neglect, or both) was associated with a lower score on both the WRAT (mean difference: -4.4 when the SD is 15 [95% confidence interval: -6.3 to -2.51) and RSPM (mean difference: -4.8 when the SD is 15 [95% confidence interval: -6.7 to -2.91). Both reported abuse and neglect were independently associated with lower reading ability and perceptual reasoning. CONCLUSIONS: Both child abuse and child neglect are independently associated with impaired cognition and academic functioning in adolescence. These findings suggest that both abuse and neglect have independent and important adverse effects on a child's cognitive development. [ABSTRACT FROM AUTHOR]

Amputation is an infrequent but devastating outcome of meningococcal septicemia. We assessed daily living functions and quality of life in a cohort of children and young people, 3 to 5 years after limb amputations following severe meningococcal disease. All participants lived with their families in the community, with minimal assistance. Participants used effective strategies to compensate for motor impairment and generally had good quality of life, despite ongoing health problems (predominantly musculoskeletal). The degree of amputation did not predict the functional outcome. The surprisingly good outcomes we report should discourage clinicians from withdrawing intensive care support because of presumed poor outcomes after multiple amputations in severe meningococcal disease.

OBJECTIVE. The objective of our study was to evaluate the effect of supplementation with docosahexaenoic acid and arachidonic acid for human milk-fed preterm infants. The primary end point was cognitive development at 6 months of age. METHODS. The study was a randomized, double-blind, placebo-controlled study among 141 infants with birth weights of <1500 g. The intervention with 32 mg of docosahexaenoic acid and 31 mg of arachidonic acid per 100 mL of human milk started 1 week after birth and lasted until discharge from the hospital (on average, 9 weeks). Cognitive development was evaluated at 6 months of age by using the Ages and Stages Questionnaire and event-related potentials, a measure of brain correlates related to recognition memory. RESULTS. There was no difference in adverse events or growth between the 2 groups. At the 6-month follow-up evaluation, the intervention group performed better on the problem-solving subscore, compared with the control group (53.4 vs 49.5 points). There was also a nonsignificant higher total score (221 vs 215 points). The event- related potential data revealed that infants in the intervention group had significantly lower responses after the standard image, compared with the control group (8.6 vs 13.2). There was no difference in responses to novel images. CONCLUSIONS. Supplementation with docosahexaenoic acid and arachidonic acid for very preterm infants fed human milk in the early neonatal period was associated with better recognition memory and higher problem-solving scores at 6 months.

OBJECTIVE. The goal was to determine the relative effects of underlying genetic factors and current management strategies on neurodevelopmental disabilities among one-year old survivors of palliation for hypoplastic left heart syndrome. METHODS. Children who underwent staged reconstruction for hypoplastic left heart syndrome and variants were assessed at 1 year of age by using a neuromuscular examination and the Bayley Scales of Infant Development II, which provide the Mental Development Index and the Psychomotor Development Index. The effects of perioperative, operative, and genetic variables on developmental scores were evaluated. RESULTS. The median birth weight was 3.3 kg (range: 2.1-4.5 kg). Eight-three patients (94%) underwent multiple operations with cardiopulmonary bypass during the first year of life (median: 2 operations). Seven patients (8%) required extracorporeal membrane oxygenation. Twenty-five patients (28%) had a confirmed or suspected genetic syndrome. At 1 year of age, the neuromuscular examination results were abnormal or suspect for 57 patients (65%). The median Mental Development Index score was 90, and 10 patients (11%) had scores of <70 (2 SDs below the general population mean). The median Psychomotor Development Index score was 73, and 42 patients (48%) had scores of <70. In multivariate analyses, younger gestational age, the presence of a genetic syndrome, and the need for preoperative intubation had significant negative effects on neurodevelopmental outcomes. No association was found with operative factors, including duration of deep hypothermic circulatory arrest. CONCLUSIONS. At 1 year of age, there was a significant incidence of neurodevelopmental disabilities in children with hypoplastic left heart syndrome and variants; motor scores were particularly concerning. Many children had suspected or confirmed genetic syndromes, which negatively affected neurodevelopmental outcomes. Surgical variables did not affect neurologic outcomes. [ABSTRACT FROM AUTHOR]

OBJECTIVE. It has been shown that bullying victimization is associated with behavior and school adjustment problems, but it remains unclear whether the experience of bullying uniquely contributes to those problems after taking into account preexisting adjustment problems. METHODS. We examined bullying in the Environmental Risk Study, a nationally representative 1994-1995 birth cohort of 2232 children. We identified children who experienced bullying between the ages of 5 and 7 years either as pure victims or bully/victims. We collected reports from mothers and teachers about children's behavior problems and school adjustment when they were 5 years old and again when they were age 7. RESULTS. Compared with control children, pure victims showed more internalizing problems and unhappiness at school when they were 5 and 7 years. Girls who were pure victims also showed more externalizing problems than controls. Compared with controls and pure victims, bully/victims showed more internalizing problems, more externalizing problems, and fewer prosocial behaviors when they were 5 and 7 years. They also were less happy at school compared with control children at 7 years of age. Pure victims and bully/victims showed more behavior and school adjustment problems at 7 years of age, even after controlling for preexisting adjustment problems at 5 years of age. CONCLUSIONS. Being the victim of a bully during the first years of schooling contributes to maladjustment in young children. Prevention and intervention programs aimed at reducing mental health problems during childhood should target bullying as an important risk factor. [ABSTRACT FROM AUTHOR]

Background and Objective: Children who experienced intrauterine growth restriction (IUGR) may be at increased risk for adverse developmental outcomes in early childhood. The objective of this study was to carry out a systematic review of neurodevelopmental outcomes from 6 months to 3 years after IUGR., Methods: PubMed, Embase, PsycINFO, Maternity and Infant Care, and CINAHL databases were searched by using the search terms intrauterine, fetal, growth restriction, child development, neurodevelopment, early childhood, cognitive, motor, speech, language. Studies were eligible for inclusion if participants met specified criteria for growth restriction, follow-up was conducted within 6 months to 3 years, methods were adequately described, non-IUGR comparison groups were included, and full English text of the article was available. A specifically designed data extraction form was used. The methodological quality of included studies was assessed using well-documented quality-appraisal guidelines., Results: Of 731 studies reviewed, 16 were included. Poorer neurodevelopmental outcomes after IUGR were described in 11. Ten found motor, 8 cognitive, and 7 language delays. Other delays included social development, attention, and adaptive behavior. Only 8 included abnormal Doppler parameters in their definitions of IUGR., Conclusions: Evidence suggests that children are at risk for poorer neurodevelopmental outcomes following IUGR from 6 months to 3 years of age. The heterogeneity of primary outcomes, assessment measures, adjustment for confounding variables, and definitions of IUGR limits synthesis and interpretation. Sample sizes in most studies were small, and some examined preterm IUGR children without including term IUGR or AGA comparison groups, limiting the value of extant studies., (Copyright © 2015 by the American Academy of Pediatrics.)

Background and Objective: Children with congenital heart disease (CHD) are at risk for developmental delay (DD). Changes in cognitive, language, and motor skills in early childhood have not been described. We report the results of a structured approach using longitudinal testing to identify problems and ensure early intervention in accordance with published guidelines., Methods: Bayley Scales of Infant Development, Third Edition, were used to assess cognitive, language, and motor skills in 99 children with CHD. Subjects were evaluated 3 to 6 times in the first 3 years of life. DD was defined as scores >1 SD below the population mean., Results: Cardiac anatomy was single ventricle (1V) in 34 subjects and 2 ventricles (2V) in 65. Medical comorbidities were present in 21% and genetic syndromes in 19%. Most subjects (75%) had DD in ≥1 area at ≥1 assessments. Subjects with 1V anatomy had equivalent outcomes to those with 2V. Cognitive and language scores declined in subjects with genetic syndromes but were stable and within the average range for subjects with 1V and 2V. Motor scores improved for subjects with 1V and 2V but remained low for those with genetic syndromes. In addition to age, need for supplemental tube feeding, longer cardiopulmonary bypass time, and shorter time since last hospitalization were significant predictors of developmental outcomes., Conclusions: DDs in young children with CHD are both common and dynamic. Providers should encourage longitudinal surveillance for children with CHD because exposure to risk and prevalence of DD change over time.

Objectives: To describe the developmental trajectories of mobility performance and daily activities in children and young adults with cerebral palsy (CP). To explore the influence of gross motor function and intellectual disability on these trajectories., Methods: Four hundred and twenty-four Dutch participants with CP (aged 1-20 years at study onset) were followed yearly over a period of 2 to 4 years. Developmental trajectories (from ages 1-16 years) were described for mobility performance and performance of daily activities, assessed by using the Vineland Adaptive Behavior Scale for gross motor function (classified by the Gross Motor Function Classification System) and intellectual disability (by IQ or school type). A subanalysis was done for performance of daily activities in a subgroup of participants without intellectual disability (aged 1-24 years)., Results: The developmental trajectories of mobility performance differed according to levels of gross motor function but not levels of intellectual disability. Intellectual disability affected the performance of daily activities, with lower overall trajectory levels for participants with intellectual disabilities. For participants without intellectual disability, high-level developmental trajectories were found, with values similar to those of typically developing children despite differences in gross motor function level., Conclusions: Mobility performance is determined mainly by levels of gross motor function. For performance of daily activities, intellectual disability was a more important determinant. Participants without intellectual disability showed developmental trajectories approaching values for typically developing participants. These estimated trajectories can guide rehabilitation interventions and future expectations for children and young adults with CP.
