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)

The relationship between energy intake and obesity in children has yielded inconsistent results. Efforts to improve dietary intake as a means of improving weight status have largely yielded disappointing results.

Self-reported energy intake for younger, but not older, overweight/obese children is higher than healthy-weight peers. In early childhood, higher (or excessive) energy intake may lead to onset of obesity, but other mechanisms may be important to maintain obesity through adolescence. (Read the full article)

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)

Pediatric osteoarticular infections can be treated with successful microbiologic and clinical outcomes with a transition from parenteral to oral therapy. The best way to determine the timing of this transition is neither well studied nor standardized.

A total of 193 (99.5%) of 194 pediatric patients with acute bacterial osteoarticular infections were successfully transitioned to oral therapy, determined by using a combination of clinical findings and C-reactive protein levels, representing the largest single-center data set analyzed.

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)

Mortality of very low birth weight infants varies widely between regions and countries; however, the variation in morbidities after adjusting for confounders has not been adequately studied.

Composite outcome of mortality or short-term morbidity for very low birth weight infants was lower in Japan than in Canada. However, marked variations in mortality and individual morbidity exist, revealing areas for improvement in each country. (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.

Behavioral techniques effectively reduce infant sleep problems and associated maternal depression in the short- to medium-term (4–16 months’ postintervention). Despite their effectiveness, theoretical concerns persist about long-term harm on children’s emotional development, stress regulation, mental health, and the child-parent relationship.

Behavioral sleep techniques did not cause long-lasting harms or benefits to child, child-parent, or maternal outcomes. Parents and health professionals can feel comfortable about using these techniques to reduce the population burden of infant sleep problems and maternal depression. (Read the full article)

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 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)

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)

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)

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)

Discussing end-of-life (EoL) care with adolescents and young adults (AYAs) is difficult. Often, such conversations are delayed or avoided, but AYAs contemplate EoL issues and want to make decisions about their care. Few established resources exist to help this process.

Results support the use of a developmentally appropriate document that allows AYAs an opportunity to share their choices about EoL care and how they would like to be remembered in the future. (Read the full article)

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)

Increased computed tomography (CT) use among adults and children presenting to emergency departments has spawned concern about associated radiation exposure. The risks and benefits of CT use for certain conditions, such as abdominal pain, among general pediatric populations remains unclear.

This study analyzes emergency department radiology trends between 1998 and 2008 among children with abdominal pain, highlighting a dramatic increase in CT use. Factors associated with CT ordering include older age, non-black race, and hospital admission. (Read the full article)

Retinal hemorrhages occur in accidental and inflicted traumatic brain injury (ITBI) and some medical encephalopathies. Large numbers and peripherally located retinal hemorrhages are frequently cited as distinguishing features of ITBI in infants, but the predictive value has not been established.

This prospective retinal imaging study found that a diagnosis of ITBI in infants and children can be distinguished from other traumatic and nontraumatic causes by the presence of >25 dot-blot (intraretinal layer) hemorrhages (positive predictive value = 93%). (Read the full article)

Significant variation in congenital hypothyroidism screening operations/performance has been observed in the United States. The origin of this variation remains unknown, in part because of a lack of evaluation. Accordingly, debates persist about optimal screening operations including laboratory testing methods.

Four distinct screening protocols applied to Michigan resident infants are compared in detecting congenital hypothyroidism overall and specific to cases characterized by high initial thyrotropin concentrations thought to have a more severe form of the disease. (Read the full article)

Chromosomal microarray analysis offers a superior diagnostic yield over karyotyping for the evaluation of individuals with developmental disabilities. Many third-party payers, however, do not reimburse for microarray testing, citing a lack of evidence that patients benefit from testing.

This study demonstrates that microarray testing frequently identifies conditions that include features requiring specific medical follow-up and that referring physicians respond to abnormal test results with appropriate clinical actions. Microarray testing, therefore, provides direct benefits to patients. (Read the full article)

School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a widely used universal prevention strategy currently implemented in >16 000 schools across the United States. Previous research has shown positive effects on school climate and school-level discipline problems.

This study reports multilevel results on data from a 4-year randomized controlled effectiveness trial of SWPBIS in 37 elementary schools. Results indicate significant impacts on children’s aggressive behavior problems, concentration problems, office discipline referrals, emotion regulation, and prosocial behavior.

Healthy sleep is essential for supporting alertness and other key functional domains required for academic success. Research involving the impact of modest changes in sleep duration on children’s day-to-day behavior in school is limited.

This study shows that modest changes in sleep duration have significant impact on the behavior of typically developing children in school. Modest sleep extension resulted in detectable improvement in behavior, whereas modest sleep restriction had the opposite effect. (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)

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)

The false-positive rate of newborn screening for classic congenital adrenal hyperplasia (CAH) remains high and has not been significantly improved by adjusting 17α-hydroxyprogesterone cutoff values for birth weight and/or gestational age. In response, 4 states have initiated second-tier steroid profile screening.

Under second-tier screening, the false-positive rate remains high, and classic CAH cases missed by screening (false-negatives) occur more frequently than reported. Physicians are cautioned that a negative screen does not necessarily rule out CAH. (Read the full article)

Several meta-analyses evaluating probiotics in preterm infants suggest a beneficial effect for the prevention of necrotizing enterocolitis and death, but less for nosocomial infection. Lactobacillus reuteri may reduce these outcomes because of its immunomodulation and bactericidal properties.

Although L reuteri did not appear to decrease the rate of death or nosocomial infection, the trends suggest a protective role consistent with the literature. Feeding intolerance and duration of hospitalization were significantly decreased in premature infants ≤1500 g. (Read the full article)

Chronic nonbacterial osteomyelitis (CNO) is a sterile inflammatory bone disorder of presumed autoimmune or autoinflammatory etiology predominantly affecting children. There are limited data on the characteristics and optimal treatment of CNO in the United States.

A US-based cohort of pediatric CNO patients revealed high rates of personal and familial autoimmunity. Coexisting autoimmunity was a risk factor for widespread involvement. Response to nonsteroidal antiinflammatory drugs was inferior to that with immunosuppressive and biologic agents. (Read the full article)

Recent investigations of pubertal onset in US girls suggest earlier maturation. The situation for US boys is unknown, and existing investigations are outdated and lack information on a key physical marker of male puberty: testicular enlargement.

US boys appear to be developing secondary sexual characteristics and achieving testicular enlargement 6 months to 2 years earlier than commonly used norms, with African American boys entering Tanner stages 2 to 4 earlier than white or Hispanic boys. (Read the full article)

There are limited data on current testing and treatment patterns for children hospitalized with pneumonia, and on whether institutional guidelines affect care.

The use of institutional clinical practice guidelines was not associated with changes in diagnostic testing, hospital length of stay, or costs for children hospitalized with pneumonia, but was associated with increased use of narrow-spectrum antibiotics. (Read the full article)

The rising burden of allergy is most evident in infancy, indicating the importance of early exposures. Reduced vitamin D status in pregnancy has been associated with atopy and respiratory outcomes, but there is less information on other early allergic outcomes.

Cord blood 25-hydroxyvitamin D₃ concentrations <50 nmol/L were highly prevalent in an Australian population. Lower vitamin D levels were associated with increased risk of eczema at 12 months of age, whereas there was no association with sensitization or food allergy. (Read the full article)

Detained youth represent a vulnerable pediatric population with worse health outcomes than their nondetained peers. To date, little work has been done to determine whether health information technologies may be effectively used to improve the health of this underserved population.

The Internet is accessible to youth involved in the juvenile justice system. A securely accessible online system to store detained youth’s health information may be both feasible and acceptable for engaging these adolescents more actively in their health care. (Read the full article)

Social and environmental risks related to substandard housing contribute to adverse health outcomes. Partnerships between the health care and legal systems can help families address such risks and help clinicians understand the legal context of health.

A medical-legal partnership colocated in a pediatric primary care setting identified and treated a large cluster of poor quality, substandard housing. Housing improvements were possible because of strong collaboration between clinicians, attorneys, community partners, and families. (Read the full article)

Heart rate continues to be the single most important indicator of well-being in a newborn. Availability of a reliable method to determine heart rate in the first minute would help determine resuscitation interventions, particularly for the extremely premature infant.

Electrocardiograms can provide a reliable, continuous heart rate in the most premature infants in the first minute of resuscitation compared with pulse oximeters. (Read the full article)

The CPT1A p.P479L variant is common to northern aboriginal populations, leads to reduced enzyme activity, and may be associated with increased infant mortality rates.

The p.P479L variant is common in British Columbia First Nations with a coastal distribution correlated with regions of high infant mortality. Homozygotes display an altered acylcarnitine profile and are overrepresented in cases of sudden unexpected infant death in these areas. (Read the full article)

Nasal continuous positive airway pressure (NCPAP) is commonly given to premature infants with nasal prongs and nasal masks. Prongs and masks appear to injure the nose of preterm infants with equal frequency.

Nasal masks are more effective than nasal prongs for preventing intubation and mechanical ventilation in premature infants within 72 hours of starting NCPAP. (Read the full article)

Postnatal growth restriction of preterm infants is a universal problem. Early "catch-up growth" has been associated with development of metabolic syndrome. In addition, preterm infants appear to be at major risk for developing increased adiposity and insulin resistance.

The consumption of a nutrient-enriched formula after hospital discharge may be beneficial in adequate for gestational age infants both in terms of head circumference growth and fat-free mass gain. (Read the full article)

Randomized controlled trials of early developmental interventions for very preterm infants demonstrate short-term benefits for infant neurobehavioral functioning. The longer-term benefits of these interventions for children and their families are not yet clear.

This randomized trial shows that home-based preventive care over the first year of life for very preterm infants has selective long-term benefits. Caregivers report less anxiety and fewer were at risk for an anxiety disorder. Preschoolers show fewer internalizing behaviors. (Read the full article)
