Adolescents living in lower-poverty neighborhoods have better mental health than youth in high-poverty contexts, but it is unclear if associations are causal. Furthermore, it is unknown why some youth benefit more than others from moving to more advantaged neighborhoods.

Using an experimental study that randomly assigned families to receive vouchers to move to lower-poverty neighborhoods, we found that recent violent crime victimization adversely modified the mental health effects of moving to better neighborhoods. (Read the full article)

The higher the predischarge bilirubin percentile reading on the hour of life–specific nomogram, the higher becomes that infant's risk of developing significant hyperbilirubinemia. Neonates in the low-risk zones (≤75th percentile) have a low risk of developing hyperbilirubinemia.

Thirty-two percent of newborns readmitted for hyperbilirubinemia had low-risk zone predischarge bilirubin percentile values, predominantly in the intermediate low-risk zone (41st–75th percentile). The intermediate low-risk zone may not be as low risk as previously thought. (Read the full article)

Forearm fractures are unique injuries which are associated with lower bone mineral density in adults and white children. The relationships among bone mineral density, 25-hydroxyvitamin D status, and risk for forearm fracture have not been investigated in African American children.

Our data support an association between both lower bone mineral density and vitamin D deficiency and increased odds of forearm fracture in African American children. Promotion of bone health is indicated in this population. (Read the full article)

Skills learned in standardized courses are estimated to last only a few months. Neonatal Resuscitation Program certification is mandatory for all pediatric residents and is valid for 2 years. Exact timing of when proficiency is lost is unknown.

Neonatal Resuscitation Program skills deteriorate immediately after certification, whereas knowledge is better retained. Significant skill deficits were seen at baseline raising concerns regarding the efficacy of the current course structure. Discrepancies in knowledge and skill retention may impact caregiver performance. (Read the full article)

Systematic screening for child abuse of all children presenting at emergency departments might increase the detection rate of child abuse but studies to support this proposal are scarce.

Systematic screening for child abuse in emergency departments is effective in increasing the detection of suspected child abuse. Training emergency department staff and requiring screening legally at emergency departments increase the extent of screening. (Read the full article)

Evaluation of neonatal surgical outcomes is necessary to guide improvements in the quality of care. Meaningful comparisons must adjust for factors that alter outcomes independent of the surgical procedures.

Herein is described a method that permits risk adjustment for the broad range of noncardiac neonatal surgery, regardless of gestational age, to permit useful comparisons for quality improvement. (Read the full article)

The 2009 influenza A (H1N1) pandemic caused illness in all age groups, but children were disproportionately affected. Children with underlying neurologic disorders were at high risk of influenza-related complications, including death.

This study provides the first detailed description of underlying neurologic disorders among children who died of influenza A (H1N1)pdm09 virus infection. (Read the full article)

Sleep disordered breathing (SDB) and behavioral sleep problems (BSPs) affect cognitive, behavioral, and language development. No studies have examined associations between SDB and BSPs across early childhood, and later special education need (SEN), on a population basis.

A history of SDB through 5 years of age was associated with ~40% increased odds of SEN at 8 years, among >11 000 children. BSPs were associated with 7% increased odds of SEN, for each additional ~12 months of reported BSPs. (Read the full article)

Little is known about how communication during pediatric asthma visits is associated with child control medication adherence 1 month after the visit.

When providers asked for caregiver input into the asthma treatment plan during the visit, caregivers reported significantly higher child medication adherence to control medications 1 month later. (Read the full article)

Previous studies suggest that abnormal findings on conventional EEG during the neonatal period are associated with death or severe brain injury in preterm infants. However, large cohort studies on preterm EEG for predicting later neurodevelopmental outcome remain scarce.

This study demonstrates precise prognostic values of conventional EEG for predicting neurodevelopmental outcome in the current perinatal care setting. Additionally, its prognostic values are independent of severe injury on neuroimaging and clinical risk factors. (Read the full article)

There are no studies to support the clinical awareness of persistent Tanner stage (TS) 4 breast development in adulthood, and forensic experts continue to use TS 4 as evidence of age <18 years in cases of alleged child pornography.

One-fourth of nonclinical images of women over 18 years of age could be considered by a single forensic expert to represent TS 4. This observation, and substantial discordance in interpretation by pediatric endocrinologists, renders testimony based on this distinction invalid. (Read the full article)

Childhood obesity is a public health concern. Although determinants of childhood overweight have been identified and their effect sizes have been calculated, prevention as well as treatment have had limited success.

We have calculated the population-based relevance of determinants of childhood overweight by using attributable risks, which can be interpreted as maximum success rates of preventive measures. New concepts were applied to estimate the relative contribution of each risk factor. (Read the full article)

Approximately 80% of all preterm children are born moderately preterm (32–36 weeks’ gestation). Moderately preterm children are at increased risk for developmental delays, but the specific neuropsychological functions that may underlie these delays are unknown.

Moderately preterm birth is associated with poorer performance in intelligence, attention, visuospatial reasoning, and executive functioning. Using gender-specific norms, our data suggest that preterm boys catch up, whereas preterm girls lag behind their peers at 7 years of age. (Read the full article)

Declining dietary omega 3 polyunsaturated fatty acids has been associated with rising allergy prevalence and fish oil is therefore of interest in allergy prevention. Supplementation during pregnancy, but not after the age of 6 months, has achieved some allergy reductions.

We assessed the effect of fish oil supplementation from birth to 6 months, which has not been investigated previously. Our results, together with previous findings, will likely help define a "window of opportunity" for allergy intervention using fish oil supplements. (Read the full article)

Risk of preterm birth (PTB) has been noted to be higher for newborns with congenital heart defects (CHDs). The role of associated anomalies, whether PTB is spontaneous or medically induced, or specific categories of CHDs have not been elucidated.

By using population-based data, we found that PTB associated with CHDs was due to spontaneous PTB. Associated anomalies accounted for a small part of this increase, and there were specific associations between categories of CHDs and PTB. (Read the full article)

Rotavirus is a major cause of acute gastroenteritis among children worldwide. Vaccines targeting rotavirus have been demonstrated to be highly efficacious against severe disease in clinical trials and postlicensure studies. Vaccine impact on mild gastroenteritis has not been well studied.

We used a novel surveillance platform consisting of telephone triage data to capture mild gastroenteritis not detected in other surveillance systems. Since rotavirus vaccine licensure, gastroenteritis-related call proportions have declined, and peak gastroenteritis-related calls are correlated with community norovirus circulation.

Critics argue that pediatric research without the potential for clinical benefit treats children as mere means to benefit others. Yet, there are no data to assess whether adolescents who participate in research, or their parents, agree with this view.

Respondents felt that by participating in research the adolescents were making important contributions to help others, and the adolescents felt proud to be doing so. These findings support the view that nonbeneficial pediatric research involves a type of charitable activity. (Read the full article)

Although the natural course of bilirubin levels has been extensively studied in general neonatal populations, there is a paucity of data regarding bilirubin trends in neonates before the development of significant hyperbilirubinemia.

This study provides data on the natural course of transcutaneous bilirubin before the development of significant hyperbilirubinemia, and on the effect of different demographic and perinatal risk factors on the rate of bilirubin increase in neonates with borderline bilirubin values.

Changes in resident work hours are believed to have an impact on resident education and patient safety.

This study provides an understanding of the impact of changes in resident work hours on the staffing strategies of children’s hospitals. (Read the full article)

Severe neonatal hyperbilirubinemia can lead to acute bilirubin encephalopathy and, subsequently, chronic bilirubin encephalopathy (CBE). This condition is preventable through routine identification and proper treatment; therefore, it is rare for permanent neurologic complications to occur.

This article describes the incidence of CBE in Canada, which is higher than previously reported in the literature. Furthermore, it describes the underlying causes of CBE and the spectrum of neurologic disease. (Read the full article)

A 2001 survey of pediatric residency training directors indicated that few programs prepared residents to intervene on tobacco. A decade later, it is not known whether programs are doing more to prepare residents to intervene effectively with patients and parents.

Despite the need for pediatricians to play a leadership role in tobacco prevention and control, most pediatric residency training programs focus more on health effects of tobacco use and smoke exposure than on how to intervene with patients and parents. (Read the full article)

Fever phobia is a ubiquitous problem throughout the world. As a result, fever is pharmacologically overtreated, and medical attention is frequently sought by worried parents.

Most Canadian parents fear their child’s fever, resulting in aggressive surveillance and treatment. Parents expect information about fever etiology and how to care for their ill child. Few parents expect antibiotics and satisfaction with care is high. (Read the full article)

Iatrogenic medical errors are an important medical care issue in the United States. Errors may be particularly important in children with chronic health conditions, especially as the prevalence of chronic conditions is increasing in children.

In a nationally representative sample, we found that pediatric inpatients with chronic conditions were at a significantly higher risk for medical errors than inpatient children without chronic conditions, controlling for severity of illness, length of stay, and other potential confounders.

Few longitudinal studies from developing countries have assessed the relation between early maternal depressive symptoms and child growth beyond age 2. The results of these studies have been inconclusive.

Early maternal depressive symptoms were related to higher odds of deficits in stature but not to deficits in weight among preschool- and school-aged children. Well-child care provides opportunities to identify maternal depressive symptoms to prevent future child growth delays. (Read the full article)

Sending and receiving sexually explicit picture and text messages via cell phone (ie, "sexting") among adolescents is publicized as a societal and public health concern, yet it is unknown whether sexting is associated with physical sexual activity or sexual risk behavior.

This study is the first to examine sexting among a probability sample of adolescents and found that sexting is associated with sexual activity, sexual risk behavior, and knowing other person(s) who have sent a sext. (Read the full article)

Pediatric obesity is a prevalent public health issue that is associated with medical and physical consequences. Clinic-based interventions for pediatric obesity are effective, but they have limited reach and are costly.

This is the first examination of an empirically informed, scalable treatment of pediatric overweight and obesity delivered in YMCAs. The results indicate that a scalable, community-based pediatric obesity intervention can produce clinically meaningful changes in weight and quality of life. (Read the full article)

Findings from 3 studies suggest that the diagnosis of venous thromboembolism in hospitalized US children has increased in recent years.

This study provides additional evidence of an increasing trend in the rate of venous thromboembolism-associated hospitalization in US children, as well as a concurrent increase in the prevalence of venous catheter procedures. (Read the full article)

The American Academy of Pediatrics and National Heart, Lung, and Blood Institute recommend routine blood pressure measurement in children. Little is known about the frequency with which blood pressure is currently measured in ambulatory pediatric settings in the United States.

Between 2000 and 2009, providers measured blood pressure during only one-third of ambulatory pediatric visits and two-thirds of pediatric preventive visits. The current rate of screening is especially low for children aged 3 to 7 years. (Read the full article)

Expedited partner therapy (EPT) is an effective method of partner treatment of sexually transmitted infections but is not used frequently. There are limited data on provider knowledge, practices, and comfort with EPT use in adolescents.

California pediatric residents have knowledge gaps and discomfort providing EPT and presence of an adolescent medicine fellowship is associated with increased EPT knowledge, use, and comfort among residents. Our findings support the need to improve EPT education in pediatric residencies. (Read the full article)

The Apgar score is a convenient method to rapidly assess the clinical status of the newborn infant. Recent literature suggests Apgar scores vary widely in preterm infants.

The Apgar signs for respiratory effort, grimace, and muscle tone demonstrated considerable disagreement in preterm infants ≤28 weeks’ gestation. Disagreement exists despite the level of respiratory intervention, continuous positive airway pressure, or intubation, and is likely independent of gestational age. (Read the full article)

Infants with hypoxic-ischemic encephalopathy suffer a high rate (>40%) of death or moderate to severe disability, even after therapeutic hypothermia. High-dose erythropoietin (Epo) reduces brain injury and improves neurologic function in animal models of neonatal hypoxic-ischemic brain injury.

Multiple doses of Epo (up to 2500 U/kg intravenously) given in conjunction with hypothermia are well tolerated in newborns with HIE. Epo doses of 1000 U/kg intravenously in cooled infants produce plasma concentrations that are neuroprotective in animal studies. (Read the full article)

Despite numerous preventive strategies including prophylaxis with 400 IU/day of vitamin D in recent years, the deficiency of vitamin D in infants is still a global health problem.

This study reveals that the risk of vitamin D deficiency is high in exclusively breastfed infants, especially in winter, despite vitamin D supplementation. Therefore, it is suggested that an adjustment of vitamin D dosage for seasonal variation might be necessary. (Read the full article)

Inflammatory bowel disease pathogenesis is incompletely understood. Previous pediatric studies suggested associations between antibiotic use and inflammatory bowel disease development but were limited by recall bias, lack of controls, incomplete antibiotic capture, or included exposures between symptom onset and diagnosis.

Our population-based cohort study suggests that certain childhood antibiotic exposures are associated with an increased risk of developing inflammatory bowel disease. Our findings have implications for understanding the condition’s pathogenesis and provide additional stimulus for reducing unnecessary childhood antibiotic use. (Read the full article)

Filling a prescription is the first step in medication adherence. Unfilled prescriptions are a documented component of nonadherence in adult and pediatric emergency departments and family practices. No one has reported the proportion of unfilled prescriptions in pediatric primary care.

This study identifies the proportion of unfilled prescriptions in a large sample of primary care pediatric patients. It describes clinical and demographic factors associated with prescription filling and suggests that electronic prescribing may improve adherence. (Read the full article)

National data from child protective services agencies have shown a 55% decrease in the incidence of substantiated cases of physical abuse from 1992 to 2009, but no study has tracked the occurrence of serious injuries due to physical abuse.

Using national data from hospitalized children, we found a statistically significant increase in the incidence of serious injuries due to physical abuse from 1997 to 2009. These results are in sharp contrast to data from child protective services. (Read the full article)

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)

Exergaming offers a physical activity (PA) alternative for youth that may be attractive in our increasingly technophilic society. Exergaming increases PA and decreases sedentary time, but most exergame studies are clinically based and focus on measuring energy expenditure during exergaming.

One-quarter of adolescents exergamed at intensity levels that could help them achieve PA recommendations. Exergamers were more likely to be female, play nonactive video games, watch ≥2 hours of television per day, be stressed about weight, and be nonsmokers. (Read the full article)

Implementing expanded vaccination recommendations has challenged primary care providers, who administer the majority of vaccines in the United States. School-located vaccination has been proposed as a means of increasing vaccination rates while reducing the burden on primary care providers.

This study assesses physicians’ support for their patients’ receipt of vaccines in school. Additionally, it compares physicians’ support for adolescent versus influenza vaccination and compares support by insurance status of their patient. (Read the full article)

There are limited data regarding the current status of the pediatric clinical trial enterprise.

Evaluation of the ClinicalTrials.gov data set allows description of the overall portfolio of clinical trials relevant to US children, which was previously not possible. (Read the full article)

Some epidemiologic evidence suggests an inverse association between sleep duration and obesity in various age groups. However, in the case of adolescents, inconsistent results have been reported, which can be partly explained by methodologic options.

Our study supports an effect of sleep duration in adiposity during adolescence and found gender differences in this association. The results are consistent by using either the traditional longitudinal approach or cross-lagged modeling. (Read the full article)

Infant behavioral dysregulation is a common concern, involving irritability, excessive crying, and problems with feeding and sleep. Previous research into its behavioral outcomes has been limited by small cohorts and short follow-up, and findings have been contradictory.

Long-term follow-up of a large cohort showed that infant behavioral dysregulation was a risk factor for maternal-reported behavior concerns at 5 and 14 years, but was unrelated to young adult mental health outcomes. (Read the full article)

The Global Trigger Tool uses a sampling methodology to identify and measure harm rates. It has been shown to effectively detect adverse events when applied in the adult environment, but it has never been evaluated in a pediatric setting.

The Global Trigger Tool can be used in the pediatric inpatient environment to measure adverse safety events. We detected a 2 to 3 times higher harm rate than previously found with different metrics in this setting. (Read the full article)

Understanding human disease genomics requires large population-based studies. There is lack of standardization, as well as social and ethical concerns surrounding the consent process for pediatric participation in a biorepository.

The study identifies specific barriers to pediatric participation in biorepositories relative to adults, and proposes strategies to improve ethical and responsible participation of pediatric-aged patients in large-scale genomics and biorepository-driven research without significantly increasing research burden for affected families.

Children investigated for alleged maltreatment have considerable physical, mental health (MH), developmental, and educational needs and often do not receive services to address these needs. The prevalence/correlates of MH services use in the current challenging financial environment is unknown.

This study demonstrates the importance of medical providers and schools for receipt of MH services for these children, but shows disparities in MH service use between white and nonwhite children. Unlike earlier findings, MH service use declined over the follow-up. (Read the full article)

Among middle-aged adults, genotype scores predict incident type 2 diabetes but do not improve prediction models based on clinical risk factors including family history and BMI. These clinical factors are more dynamic in adolescence, however.

A genotype score also predicts type 2 diabetes from adolescence over a mean 27 years of follow-up into adulthood but does not improve prediction models based on clinical risk factors assessed in adolescence. (Read the full article)

Most term and late preterm infants with neonatal encephalopathy have not had recognized asphyxial birth events. Several nonasphyxial risk factors for neonatal encephalopathy have been identified in previous studies.

In a large sample, we confirm the association of several nonasphyxial factors with neonatal encephalopathy, including markers of intrauterine exposure to infection or inflammation, intrauterine fetal growth restriction, and birth defects. We identify steps that would improve studies of neonatal encephalopathy. (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)

Clinical guidelines for the evaluation of suspected physical abuse in young children emphasize performing radiologic imaging to screen for occult fractures. Little is known about the degree of adherence to guidelines for screening for occult fractures among pediatric hospitals.

Adherence to guidelines related to screening for occult fractures in young children diagnosed with physical abuse varies significantly among pediatric hospitals. Use of screening in infants who have injuries associated with a high likelihood of abuse also varies among pediatric hospitals. (Read the full article)

Concerns persist about sexual disinhibition after human papillomavirus (HPV) vaccination of preteenage girls. Self-reported surveys have indicated few anticipated behavior changes after HPV vaccination. Little is known about sexual activity–related clinical outcomes after HPV vaccination.

Utilizing managed care organization electronic data, we evaluated the incidence of adverse outcomes of sexual activity among vaccinated preteenage girls and found little difference between those who received HPV vaccine and those who did not. (Read the full article)

Oral health researchers and policy makers primarily use 4 national surveys to examine use of dental services among US children. Estimates from the surveys may vary, posing a challenge to population-based monitoring.

The authors of this study compared estimates of dental service use and delayed dental care obtained from 4 commonly used health surveys to appraise their utility for guiding pediatric oral health research and policy. (Read the full article)
