Children born late preterm (34–36 weeks’ gestation) are at increased risk of adverse early childhood outcomes compared with term-born children. The impact of the neonatal experience on longer-term outcomes of these infants has not yet been well considered.

This study provides information regarding the development of late preterm infants at 3 years. Late preterm infants who received neonatal intensive or high-dependency care had similar developmental outcomes to children born late preterm who did not receive this care. (Read the full article)

Anecdotal accounts that suggest elopement behavior occurs in children with autism spectrum disorders (ASDs), that injuries and fatalities can result, and that associated family burden and stress are substantial. However, there has been little research characterizing the phenomenon or its frequency.

Nearly half of children with an ASD elope, and more than half of these "go missing." Elopement is associated with autism severity, and is often goal-directed. Addressing elopement behavior is an important aspect of intervention for many individuals with ASDs. (Read the full article)

Brain maturation processes of very premature children are adversely affected by serious neonatal infections. Differences in brain development persist into childhood and adolescence, and underpin widespread neurocognitive and behavioral deficits in very preterm children.

We present evidence for long-term beneficial effects of early nutritional intervention with glutamine in very preterm infants on brain development at 8 years of age, mediated by a decrease in the number of serious neonatal infections. (Read the full article)

Today’s adolescents increasingly use the Internet to explore their sexual identity. There is public concern that the Internet, because of its accessibility, affordability, and anonymity, stimulates adolescents to engage in online sexual risk behavior (eg, sending sexual images to strangers).

This 4-wave panel study is the first to delineate the typical development of online sexual risk behavior, its relationship with offline sexual risk behavior, and the factors (eg, sensation seeking, family cohesion, life satisfaction, education, online communication) that predict both behaviors.

With increasing survival rates, there is growing interest in long-term quality of life among patients with univentricular heart defects, and neurodevelopmental deficits play a major role in adverse outcome.

Although median cognitive performance was within normal limits, major neurodevelopmental impairment was found in one-fourth, and minor neurologic dysfunction in almost half of patients. Brain MRI showed mostly ischemic findings of different degrees in the majority of patients. (Read the full article)

Developmental screening using standardized tools has been endorsed by professional groups to improve rates of identification and referral for young children who have developmental delays. Little is known about the effectiveness of these tools among a high-risk urban population.

Using a randomized design, we found that a program of developmental screening improved the percentage and time to identification of developmental delay, referral, and eligibility for early intervention among a poor, racially diverse urban population of young children. (Read the full article)

Infants and toddlers with deformational plagiocephaly (DP) score lower on developmental measures than children without DP and lower than expected relative to test norms.

This study is the first to examine developmental outcomes in preschool-aged children with DP relative to demographically similar children without DP using a standardized, clinician administered assessment. (Read the full article)

Paternal mental disorders during the postnatal period are associated with an increased risk for behavioral and emotional problems in their children; however, less is known about the effect of fathers’ mental health during pregnancy on children’s development.

The study demonstrated a positive association between fathers’ prenatal mental health and their children’s subsequent socioemotional and behavioral development. Psychological distress in fathers was associated with a risk for emotional difficulties in their children at 36 months of age. (Read the full article)

Children with sickle cell anemia are at risk of central nervous system damage, including stroke. Even children without evidence of abnormality on neuroimaging are at risk of significant declines in neurocognitive function, starting at early ages.

This study adds the observation that poorer neurocognitive and behavioral function is associated with older age in infants and toddlers with sickle cell anemia, much earlier than previously expected. (Read the full article)

In inverse proportion to the steadily declining under-5 mortality rate, prevalence of childhood disability has doubled in the past decade in Bangladesh. The Rapid Neurodevelopmental Assessment (RNDA) tool has been shown to be reliable and valid for assessment of a range of neurodevelopmental impairments (NDIs) and disabilities in children younger than 2 years. There is currently a lack of professional expertise for assessing NDIs in 2- to 5-year-old children in low- and middle-income countries.

We developed a set of instruments as part of the RNDA for administration by a single professional with experience in child development to assess >2- to 5-year-old children for a wide range of NDIs. The tool was acceptable to mothers, interrater reliability was high, and proportions of children with NDIs were elevated among the lowest income groups and in stunted children, demonstrating discriminant validity. The RNDA was valid for identifying >2- to 5-year-old children with a range of NDIs, especially in cognitive, behavior, and motor functions. Validity of the RNDA for vision, hearing, and seizure disorders needs further research. (Read the full article)

Peer victimization predicts numerous health risks. Lesbian, gay, and bisexual (LGB)-identified youth report greater peer victimization than do heterosexual-identified youth. No longitudinal studies have been conducted on developmental trends of peer victimization and emotional distress among LGB and heterosexual youth.

We provide the first longitudinal evidence on developmental trends of peer victimization and emotional distress for LGB- and heterosexual-identified youth. The findings suggest peer victimization of LGB-identified youth decreases in absolute, but not necessarily relative, terms and contributes to later emotional distress disparities.

In humans, the brain growth spurt begins in the last trimester of pregnancy and extends through the first 2 years of life. Studies show poor cognitive and motor development among children who have iron deficiency anemia in infancy.

Prenatal iron deficiency anemia in the third trimester affects child mental development. Prenatal micronutrient supplementation with sufficient iron protects child mental development even when the woman’s iron deficiency anemia is not properly corrected during pregnancy. (Read the full article)

Accurately identifying ill hospitalized children with vital signs concerning for clinical deterioration is fundamental to inpatient pediatrics. Normal vital sign ranges for healthy children are useful for outpatient practice but have limited application to detecting deterioration in the hospital setting.

Percentile curves for heart and respiratory rate in hospitalized children were developed and validated. The distributions differed from existing reference ranges and early warning scores. They may be useful to identify vital signs deviating from ranges expected among hospitalized children. (Read the full article)

Cognitive and motor developmental test scores of preterm and late preterm infants increase with gestational age. Developmental test scores in full-term infants have not previously been considered to relate to gestational age.

In a cohort of healthy, full-term infants, 37 to 41 weeks, 12-month mental and psychomotor scores on the Bayley Scales of Infant Development increased with gestational age, suggesting that neurodevelopment is optimal in infants born at 39 to 41 weeks. (Read the full article)

Prompt, high-quality diagnosis of acute pyelonephritis and later identification of children with scarring are important to prevent future complications. Examination by dimercaptosuccinic acid scan is the current clinical gold standard but is not routinely performed.

Procalcitonin demonstrated a more robust predictive ability, compared with C-reactive protein or white blood cell count, to selectively identify both children who had acute pyelonephritis during the early stage of urinary tract infections, as well as those with late scarring.

Infants with a diverse gut microbial flora are less likely to develop eczema and allergy.

Parental sucking of their infant’s pacifier is associated with a reduced risk of allergy development and an altered oral flora in their child. Transfer of oral microbes from parent to infant via the pacifier might be used in primary prevention. (Read the full article)

Assessment of general movements (GM) in early infancy is predictive of adverse neurologic outcome, particularly cerebral palsy. There is limited evidence of the predictive value of GM for other domains of neurodevelopment such as language and cognitive impairment.

Abnormal GM in preterm infants in the first 3 months postterm are predictive of a range of neurodevelopmental outcomes in early childhood. GM at 3 months are more accurate at distinguishing later neurodevelopment impairment than those at 1 month. (Read the full article)

Neonatal infections are frequent complications in very preterm infants, already at high risk of neurologic and cognitive disabilities. Few studies have linked neonatal infections and neurodevelopmental outcomes. Those that did evaluated children only to the age of 22 months.

This study assessed the respective effects of early- and late-onset sepsis and their association with 5-year neurodevelopmental outcomes. We identified a significant and cumulative risk of cerebral palsy when episodes of early- and late-onset sepsis were associated. (Read the full article)

Children with autism spectrum disorder (ASD) and those with ADHD are at risk for problematic video game use. However, group differences in media use or in the factors associated with problematic video game use have not been studied.

Boys with ASD and ADHD demonstrated greater problematic video game use than did boys with typical development. Inattention was uniquely associated with problematic use for both groups, and role-playing game genre was associated with problematic use among the ASD group only. (Read the full article)

Rehabilitation of people with cerebral palsy aims to achieve and maintain optimal performance in mobility and daily activities. Although insight into the developmental trajectories of activities from childhood into adulthood is important, little is known about long-term development.

The gross motor function of children with cerebral palsy determines the developmental trajectories of mobility performance but not of daily activities, where intellectual disability was shown to be the determining factor. (Read the full article)

A large and growing literature has demonstrated significant associations between the use of spanking and later child aggression, but we know less about paternal spanking, effects of spanking on cognitive development, and longer-term effects.

Accounting for a broad array of risk factors, spanking predicts both aggression and receptive vocabulary across the first decade of life. Importantly, we include paternal spanking, cognitive outcomes, and a longitudinal span longer than that of much of the literature. (Read the full article)

Several studies have documented earlier onset of pubertal maturation in girls, with several potential factors attributed to the earlier onset.

This study demonstrates earlier maturation in white non-Hispanic girls, with greater BMI linked as a major factor. The entire distribution of pubertal timing has shifted to a younger age, suggesting redefinition of ages for both early and late maturation. (Read the full article)

Global health is of increasing interest and relevance to North American pediatric trainees. Opportunities for resident global health training and exposure are most often limited to electives or trainees in dedicated global health tracks.

A series of short, structured, participatory global child health modules improved knowledge and were well received and integrated within academic programs. Such modules enable global health learning for all residents, including those who never intend to practice overseas. (Read the full article)

Prenatal and postnatal organophosphate (cholinesterase inhibitor) pesticide exposure has been associated with delays in attention, memory, intelligence, and inhibitory control. Two recent studies reported decreased attention and working memory with greater exposure to organophosphates in boys but not in girls.

This is the first study to report associations between decreased acetylcholinesterase activity, a stable marker of cholinesterase inhibitor pesticide exposure, and lower overall neurodevelopment, attention, inhibitory control, and memory. These associations were present in boys but not in girls. (Read the full article)

Children with autism spectrum disorders (ASD) or attention-deficit/hyperactivity disorder (ADHD) are at increased risk for sleep disturbances and excessive media use. However, the relationship between media use and sleep in children with ASD or ADHD has not been studied.

In-room access to screen-based media and video game hours were associated with less sleep among boys with ASD. The relationships between media use and sleep were much more pronounced among boys with ASD than among boys with ADHD or typical development. (Read the full article)

Early adiposity rebound is associated with future obesity and an increased risk of development of type 2 diabetes and coronary heart disease in adult life.

This study shows that early adiposity rebound is associated with future obesity and metabolic consequences of higher triglycerides, atherogenic index, apolipoprotein B, and blood pressure and lower high-density lipoprotein cholesterol at 12 years of age. (Read the full article)

Cranial ultrasound is routinely used in identifying cerebral abnormalities in premature infants. Grade III and IV intraventricular hemorrhages, cystic periventricular leukomalacia, and late ventriculomegaly are all known predictors of adverse neurodevelopmental sequelae in these infants.

We reviewed neurodevelopmental outcomes among 2414 extreme preterm infants. Infants with grades I and II intraventricular hemorrhage had increased rates of neurosensory impairment, developmental delay, cerebral palsy, and deafness at 2 to 3 years’ corrected age. (Read the full article)

Children with congenital heart disease demonstrate a high prevalence of low-severity developmental problems in the areas of language, motor skills, attention, and executive function. Systematic evaluation has been recommended to promote early detection of problems and ensure appropriate intervention.

This study presents results of longitudinal testing in early childhood. Developmental delays were common. Feeding difficulty and medical and genetic comorbidities increased risk for delays. Exposure to risk and prevalence of delay change over time; therefore, repeated evaluations are warranted. (Read the full article)

It is known that adult language input is important to healthy language development and that preterm infants are at risk for language delay.

This is the first study to provide evidence that preterm infants’ exposure to adult words in the NICU before the mother’s due date are associated with better cognitive and language outcomes at 7 and 18 months’ corrected age. (Read the full article)

Greater numbers of invasive procedures from birth to term-equivalent age, adjusted for clinical confounders, are associated with altered brain microstructure during neonatal care and poorer cognitive outcome at 18 months’ corrected age in children born very preterm.

Altered myelination at school age is associated with greater numbers of invasive procedures during hospitalization in very preterm children without severe brain injury or neurosensory impairment. Greater numbers of invasive procedures and altered brain microstructure interact to predict lower IQ. (Read the full article)

Prenatal lipid-based nutrient supplementation has been demonstrated to increase birth length. However, the impact of this intervention on infant growth and morbidity is unknown.

Infants from mothers who were given prenatal lipid-based nutrient supplements showed decelerated linear growth. The gain in length at birth related to prenatal lipid-based nutrient supplementation was not sustained during infancy. (Read the full article)

Preterm infants have transiently lowered thyroid hormone levels during the early postnatal period. Past research suggests that low thyroid hormone levels are related to cognitive and developmental deficits in children born preterm.

Contrary to expectations, in this study of children born <30 weeks’ gestation, higher concentrations of free thyroxine over the first 6 weeks of life were associated with poorer cognitive function at 7 years of age. (Read the full article)

Serotonin is critical in early brain development, creating concerns regarding prenatal exposure to factors influencing serotonin levels, like selective serotonin reuptake inhibitors (SSRIs). Prenatal SSRI use was recently associated with autism; however, its association with other developmental delays is unclear.

This population-based case-control study in young children provides evidence that prenatal SSRI use may be a risk factor for autism and other developmental delays. However, underlying depression and its genetic underpinnings may be a confounder. (Read the full article)

Investigations of adolescents’ sexual risk behavior have focused on factors such as parental monitoring, deviant peer affiliation, and daring that occur during early and midadolescence. Less is known about early childhood precursors to adolescent sexual risk behavior.

This prospective longitudinal study identifies parenting practices and mothers’ depressive symptomatology during early childhood as precursors to later sexual risk behavior and involvement in pregnancy in adolescent boys, with deviant peer affiliation during emerging adolescence mediating these relationships. (Read the full article)

A limited number of studies have identified distinct patterns of child sleep duration, which appear to have implications for health and well-being.

This article identifies distinct patterns of sleep duration during early childhood and demonstrates that these have important implications for health-related quality of life. (Read the full article)

Poor health in children is associated with exposure to family violence and disruption. Telomere length has been hypothesized to be a lasting biological indicator of exposure to early adversity and potentially predictive of negative health outcomes throughout the life course.

Telomere length reflects exposure to family violence and disruption and may be an early indicator of the biological impact of early adversity. Children exposed to interpersonal violence and family disruptions had significantly shorter telomeres. Gender moderated these associations. (Read the full article)

Rates of performing skeletal survey (SS) for young children presenting with fractures and at risk for abuse vary substantially across providers, with disparities associated with patients’ characteristics. Lack of consensus regarding indications for SS also contributes to this variation.

The results of this study provide a set of explicit consensus guidelines, based on the literature and on the knowledge of experts from several medical specialties, for identifying children with fractures who should undergo an initial SS. (Read the full article)

Children born late and moderately preterm are at increased risk of developmental problems compared with term-born peers. Screening for developmental problems in the early years may thus aid in the early identification of children at risk for adverse outcomes.

The Parent Report of Children’s Abilities-Revised has good concurrent validity and 90% sensitivity and 76% specificity for identifying moderate/severe cognitive developmental delay in infants born late and moderately preterm. This parent questionnaire may be used as a clinical screening tool. (Read the full article)

XY disorders of sex development have a diverse etiology and often present with atypical genitalia in the newborn period. Sex assignment in those cases in whom this is marked genital ambiguity is a rare, challenging situation that requires multidisciplinary input.

An international registry has shown temporal changes over the last 3 decades in the practice of sex assignment with a greater proportion of severely affected infants being raised as boys, raising the need for long-term monitoring of these children. (Read the full article)

Previous studies examining developmental outcomes associated with late preterm and early term birth have shown mixed results. Many of these studies did not fully take into account the role of the social environment in child development.

Social factors, not late preterm or early term birth, were the strongest predictors of poor developmental outcomes at 2 to 3 and 4 to 5 years. The influence of mild prematurity may lose strength beyond the neonatal period. (Read the full article)

Neurodevelopment can be adversely affected by viral infections. Human herpesvirus-6 (HHV-6) is similar to cytomegalovirus and can cause central nervous system disease. Congenital HHV-6 infection occurs in ~1% of live births, with unknown neurodevelopmental consequences.

HHV-6 congenital infection is associated with lower scores on the Bayley Scales of Infant Development II Mental Development Index compared with control infants at 12 months of age and may have a detrimental effect on neurodevelopment. (Read the full article)

In developed countries, child health disparities across wealth gradients are commonly widening; at the same time, child mortality in low- and middle-income countries is declining. Whether these declines are associated with widening or narrowing disparities is unknown.

A systematic analysis of the evidence on child mortality gradients by wealth in less-developed countries shows that mortality is declining fastest among the poorest in most countries, leading to declining disparities in this important indicator of child health. (Read the full article)

Infants with Prader-Willi syndrome suffer from hypotonia, muscle weakness, and motor developmental delay and have increased fat mass combined with decreased muscle mass. Growth hormone improves body composition and motor development.

Ultrasound scans confirmed decreased muscle thickness in infants with Prader-Willi syndrome, which improved as result of growth hormone treatment. Muscle thickness was correlated to muscle strength and motor performance. Catch-up growth in muscle thickness was related to muscle use independent of growth hormone. (Read the full article)

White matter abnormality (WMA) on neuroimaging is considered a crucial link with adverse neurodevelopmental outcome in preterm infants. Brain MRI is more sensitive in detecting WMA than cranial ultrasound (CUS), but questions remain about timing and prognostic value of modalities.

Near-term CUS and MRI abnormalities were associated with adverse 18- to 22-month outcomes, independent of early CUS and other factors, underscoring the relative prognostic value of later neuroimaging in this large, extremely preterm cohort surviving to near-term. (Read the full article)

Parental depression is associated with adverse child outcomes. It is important to understand possible mediators and moderators. Several studies suggest that the family environment or parenting style may be potential pathways for transmission of risk from parents to children.

Paternal depression appears to exert its influence on children’s outcomes through an effect on family functioning (couple conflict and maternal depression), whereas maternal postnatal depression appears to affect children through other mechanisms, potentially including direct mother-infant interaction and care.

Bruising is common in young victims of physical abuse as well as in cases of accidental trauma. There is uncertainty regarding which young children with bruising require evaluation with skeletal survey for possible abuse.

The results of this study provide guidelines, based on the literature and knowledge of experts, for identifying children <24 months presenting for care in the hospital setting with bruises, who should and should not undergo skeletal survey. (Read the full article)

Previous trials reported no significant effect of triamcinolone acetonide aqueous nasal spray on growth velocity of children with perennial allergic rhinitis. However, they did not conform to Food and Drug Administration guidelines for evaluating effects of intranasal corticosteroids on growth.

This is the first published study consistent with the 2007 Food and Drug Administration–recommended study design evaluating growth velocity in children aged 3–9 years with perennial allergic rhinitis treated with triamcinolone acetonide or placebo for 12 months. (Read the full article)

There is growing evidence reporting that moderately preterm, late preterm, and early term infants are at increased risk of developmental delay. The characteristics of this association are not well established in the literature.

In a sample of infants born between 32 and 41 weeks, there was an inverse and "dose response" relationship between gestational age and developmental delay risk using the ASQ at 8 and 18 months of corrected postnatal age. (Read the full article)

Although there is evidence regarding comorbidity of physical and mental disorders from clinical samples of specific disorders and treatment registries, there is limited evidence from systematic samples of youth with comprehensive information on the full range of mental and physical disorders.

This report is the first study to investigate the specificity of associations between a broad range of mental and physical conditions by using a large, systematically obtained pediatric sample with enriched information from electronic medical records and direct interviews. (Read the full article)

Both obesity and developmental disabilities have increased in recent decades; however, the full long-term effects of prepregnancy obesity on a child’s psychosocial development remain unknown. Limited studies suggest associations between maternal prepregnancy obesity and child psychosocial development.

This study in 6-year-old children provides evidence that severe prepregnancy obesity is associated with adverse child psychosocial outcomes, including attention-deficit/hyperactivity disorder. These findings were not explained by many pregnancy and postpartum factors related to maternal obesity or child development. (Read the full article)
