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)

Many young children are at risk for caries, which is the most common chronic disease of childhood. As primary teeth begin to develop in utero, prenatal influences are believed to affect the integrity of enamel and subsequent resistance to decay.

This study shows, for the first time, that maternal prenatal 25-hydroxyvitamin D levels may have an influence on the primary dentition and the development of early childhood caries. Specifically, lower levels are associated with increased risk of caries in infants. (Read the full article)

Home oxygen has been safely incorporated into emergency department management of bronchiolitis in certain populations. After discharge, a small proportion of patients (2.7%–6%) require subsequent admission. For patients managed successfully as outpatients, pediatricians report variable practice styles and comfort levels.

Our results define the clinical course and outpatient burden associated with discharge on home oxygen. By using an integrated health care system, we captured slightly higher rates (9.4%) of subsequent admission and found fever to be associated with this outcome. (Read the full article)

Previous studies that reported learning deficits among children with oral clefts mostly used small, clinic-based samples prone to ascertainment bias. No previous studies in the United States have used a population-based sample and direct testing of academic achievement.

Using a large population-based sample from the United States and standardized school tests for achievement, we found that children with oral clefts scored significantly lower than their classmates on all evaluated domains of achievement and had higher rates of learning disability.

Children with attention-deficit/hyperactivity disorder (ADHD) have poorer academic and social functioning and more language problems than typically developing peers. However, it is unknown how language problems impact the academic and social functioning of these children.

Language problems are common in children with ADHD and are associated with markedly poorer academic functioning independent of ADHD symptom severity and comorbidities. There was little evidence that language problems were associated with poorer social functioning for children with ADHD. (Read the full article)

The widely disseminated National Institute on Alcohol Abuse and Alcoholism screening tool for adolescent alcohol use was developed based on epidemiologic data. It has not been validated in a clinical sample and does not screen for tobacco or drug use.

This study found that a measure that expanded the National Institute on Alcohol Abuse and Alcoholism adolescent alcohol use tool to include tobacco and drugs was sensitive and specific for identifying substance use disorders in a pediatric clinic patient population. (Read the full article)

Noonan syndrome is associated with a bleeding diathesis and abnormal coagulation tests.

Bleeding diathesis in Noonan syndrome was evaluated by using a validated bleeding score. For the first time, platelet function was fully investigated, and a significant prevalence of platelet abnormalities likely to contribute to the bleeding diathesis was found. (Read the full article)

Owing to genetic variability in its metabolism, codeine can lead to fatal toxicity or inadequate treatment in pediatric subpopulations and several guidelines have recommended against its use in children. Little is known about codeine prescribing for children in the United States.

There has been a small decline in pediatric codeine prescriptions overall in emergency departments, but no change in prescription for children who have cough or upper respiratory infection, despite professional recommendations against this practice. Substantial numbers of children are being prescribed codeine annually. (Read the full article)

Early establishment of a dental home is critical for addressing the "silent epidemic" of early childhood caries. Physicians and dentists have worked to improve children’s access to dental care, but little is known about caregivers’ role in this context.

Addressing factors that affect the establishment of a child’s dental home, such as caregivers’ dental neglect and problem-driven care-seeking behaviors, is essential. Caregiver engagement seems to be pivotal for increasing use of preventive services while decreasing episodic and problem-initiated care. (Read the full article)

The American Academy of Pediatrics has recommended that sibling donors should have an independent advocate. Defining the need for and role of this advocate is hampered by a lack of empirical data.

This study provides prospective family data regarding siblings’ experiences during HLA typing and donation pre- and posttransplantation. Most family members, including the siblings, perceive no choice in typing or donation, yet have few concerns and report positive aspects to participating. (Read the full article)

Congenital pulmonary malformations are mostly identified prenatally. At birth, some children develop respiratory distress, which may be sufficiently severe to require mechanical ventilation and immediate surgery. The factors predictive of neonatal respiratory distress are not well defined.

Malformation volume and prenatal signs of intrathoracic compression are significant risk factors for respiratory complications at birth in fetuses with pulmonary malformations. In such situations, the delivery should take place in a tertiary care center. (Read the full article)

As technical improvements of pharmacogenetics (PGx) continue to be made, little is known about the perceptions of the public, in particular parents and children, on the topic of PGx.

If PGx testing is for oneself, differences in opinion are due to baseline PGx knowledge, regardless of whether respondents are parents or not. If PGx testing is for children, parents would prioritize their own understanding above their child’s assent. (Read the full article)

Population-based references of birth weight for gestational age are useful indices of birth size in clinical and research settings.

This article uses 2009–2010 US natality data and corrects for likely errors in gestational age dating to yield an up-to-date birth weight for gestational age reference. (Read the full article)

Hypothermia treatment of neonatal encephalopathy reduces death and disability from 66% to 50%; additional neuroprotective therapies are needed. We previously found in animal models that adding 50% xenon to the breathing gas during cooling doubled neuroprotection.

This clinical feasibility study used 50% xenon for 3 to 18 hours in 14 cooled infants with cardiovascular, respiratory, and amplitude-integrated EEG monitoring. This depressed seizures, with no blood pressure reduction. Xenon is ready for randomized clinical trials in newborns. (Read the full article)

Approximately 20% of US child passenger deaths involve an alcohol-impaired driver, typically in the child’s own vehicle. The higher the blood alcohol concentration of a driver, the more likely his or her child passenger was unrestrained in the fatal crash.

The risk of a child passenger dying while being transported with an alcohol-impaired driver varies meaningfully across states. These state-specific rates may help to inform renewed prevention efforts. (Read the full article)

Chorioamnionitis (CAM) is a major risk factor for early-onset neonatal sepsis. The Committee on the Fetus and Newborn recommends extending the duration of antimicrobial therapy in neonates exposed to CAM and intrapartum antibiotics if laboratory data are abnormal, even if culture results are sterile.

When managed by using a strategy similar to recent Committee on the Fetus and Newborn guidelines, a large number of term and late-preterm infants exposed to CAM who had sterile blood culture findings were treated with prolonged antibiotic therapy, subjected to additional invasive procedures, and had prolonged hospitalization.

Central line–associated bloodstream infections (CLABSI) are common types of hospital-acquired infections associated with high morbidity and cost. In recent years, quality improvement initiatives have demonstrated how to reduce the incidence of CLABSI.

This study presents nationally representative estimates of the cost and length of stay attributable to pediatric CLABSI. We make the business case to justify quality improvement prevention initiatives and the adoption of strategies for cost-effective management of CLABSI. (Read the full article)

Down syndrome is an independent risk factor for severe respiratory syncytial virus infection and subsequent hospitalization.

This observational study suggests that immunoprophylaxis may reduce respiratory syncytial virus-related hospitalization by 3.6-fold (95% confidence interval, 1.5–8.7) in children with Down syndrome overall. (Read the full article)

Several experimental and observational studies reveal an association between exposure to alcohol consumption in movies and youth drinking, but little is known about the effect of such exposure on drinking onset among low-risk adolescents.

In a longitudinal study, exposure to alcohol consumption in movies was associated with drinking initiation in a sample of adolescents from 6 European countries who had never drunk alcohol and were attitudinally nonsusceptible to future use at the time of exposure. (Read the full article)

Previous studies have shown that food advertisements influence caloric intake among children. However, individual susceptibility to food advertisements has not been examined thoroughly.

This study examines the role of impulsivity in the effect of food advertisements. An advergame promoting snacks overruled refraining from eating, especially among impulsive children. The findings suggest that impulsivity plays an important role in susceptibility to food advertisements. (Read the full article)

Children receive only half of recommended health care; disadvantaged children have higher risk of unmet needs. Practice coaching combined with quality improvement using rapid-cycle feedback has potential to help practices meet quality standards and improve pediatric health care delivery.

The Practice-tailored Facilitation Intervention led to large and sustained improvements in preventive service delivery, including substantial numbers of disadvantaged children, and in multiple simultaneous health care domains. Practice-tailored facilitation holds promise as a method to advance pediatric preventive care delivery. (Read the full article)

Type 2 diabetes mellitus is one of the fastest growing pediatric chronic illnesses worldwide and disproportionately affects indigenous people from all continents.

These data support the growing body of evidence that peer mentoring is an attractive strategy for teaching health behaviors and improving health outcomes in children. (Read the full article)

It is well-established that parental smoking is associated with adolescent smoking initiation and regular tobacco use. However, we know less about how exposure to specific types of parental smoking affect adolescent smoking and progression to regular smoking in young adulthood.

Among adolescents with parents who are nicotine dependent, each previous year of parental smoking increases the likelihood they will be in a heavy smoking trajectory. Parental smoking cessation early in their children’s life is critical to prevent smoking in families. (Read the full article)

Although a number of randomized controlled trials of erythropoietin administration to preterm infants have been performed, few studies have reported 2-year or longer neurodevelopmental outcomes, and no studies have evaluated neurodevelopmental outcomes of infants randomized to receive Darbepoetin.

This is the first prospectively designed study to evaluate the neurocognitive outcomes of preterm infants randomized to receive Darbepoetin or erythropoietin compared with placebo. Infants in the ESA groups had significantly higher cognitive scores compared with the placebo group. (Read the full article)

Quality measures developed by the Pediatric Quality Measures Program are required to assess disparities in performance according to special health care need status. Methods are needed to identify children according to level of medical complexity in administrative data.

The Pediatric Medical Complexity Algorithm is a new, publicly available algorithm that identifies the small proportion of children with complex chronic disease in Medicaid claims and hospital discharge data with good sensitivity and good to excellent specificity. (Read the full article)

Preterm birth is strongly associated with alterations in brain development and long-term neurocognitive impairment that are not fully explained by environmental factors.

Common genetic variation in genes associated with schizophrenia and lipid metabolism modulates the risk for preterm brain injury; known susceptibilities to neurologic disease in later life may be exposed by the stress of preterm birth. (Read the full article)

A large majority of preschool and young school age children with mental health problems do not receive services and little is known about the determinants of service use in this age group.

Behavioral, not emotional, disorders increase service use but only if impairment is present. Such impairment may operate via increased parental burden and parent and caregiver problem recognition. Low socioeconomic status has an independent effect increasing service use. (Read the full article)

Primary HHV-7 infection is almost universal by age 5 years and is causally associated with exanthem subitum, febrile seizures, and febrile status epilepticus. The consequences of delayed primary infection are unknown, although encephalitis has been reported in one adult.

Delayed primary HHV-7 infection can cause serious neurologic disease as identified in 3 adolescents, 2 with encephalitis and 1 with Guillain-Barré syndrome. Serologic tests to distinguish primary from past HHV-7 infection are imperative when HHV-7 DNA is present in CSF. (Read the full article)

Curtailed sleep in children has been found to be associated with increased cardiovascular disease risk factors, including obesity. Few existing studies have examined measures of adiposity beyond BMI or have examined the effects of being chronically sleep curtailed.

In this cohort of children who had research-level measures of sleep, BMI, total fat mass, and fat mass distribution, we found that chronic sleep curtailment from infancy to age 7 years was associated with higher overall and central adiposity in mid-childhood. (Read the full article)

Inadequate nutrient intake can compromise a child’s nutritional status, which may affect immune function. Improving dietary intake via a follow-up formula may support appropriate immune responses and improve a child’s ability to resist infection.

Children who consumed an experimental follow-up formula had fewer episodes and shorter duration of acute respiratory infections, as well as less antibiotic treatment, and fewer days missed of day care due to illness. (Read the full article)

Adolescents with chronic disease are a diverse population with common needs for transition. Disease-specific interventions have shown promise at improving patient outcomes but with substantial personnel and resource costs. Whether a generic approach across diseases may be useful is unknown.

This study is among the first to evaluate a generic (across disease) approach to transition of adolescents to adult care. The approach demonstrated promise and cost savings due to reduced personnel requirement and use of low-cost technology dissemination methods. (Read the full article)

Children who experience outpatient adverse drug events represent 0.5% of pediatric emergency department visits. The subset of children with complex chronic conditions often take multiple medications, but the incidence and severity of adverse drug events in these children is unknown.

Children with complex chronic conditions have a higher risk of emergency department visits related to adverse drug events, compared with other children. The implicated drugs with the highest rates include psychotropic agents, antimicrobial agents, anticonvulsants, hormones/steroids, and analgesics. (Read the full article)

Reasons for childhood immunization delay include parental intent and barriers such as transportation. To date there has been 1 study of the association of delayed vaccination and seizures, which found measles-mumps-rubella and measles-mumps-rubella-varicella vaccines are both associated with a higher rate of seizures if received after 15 months of age.

Our study found no association between the timing of vaccination and occurrence of seizures in the first year of life. By using different methods, our results support the observation that delaying vaccination with measles-containing vaccines past 15 months of age increases the incidence of postvaccination seizures.
