The retention and use of residual bloodspots is a practice of many state newborn screening programs. This practice has become controversial, and little is known about public attitudes on the retention and research use of newborn residual bloodspots.

This study offers a detailed analysis of public attitudes regarding bloodspot retention and use for biomedical research. The results also offer insights on how education regarding this practice influences support for newborn screening and residual bloodspot use. (Read the full article)

Few studies have examined the reliability of clinical findings in pediatric appendicitis. Clinical prediction rules are most useful if the included variables are reliable across practice settings and practitioners.

Among children who present with possible appendicitis, the interrater reliability varied considerably for patient history and physical examination variables. Those variables with the highest degree of reliability may be best suited for inclusion in appendicitis clinical prediction rules. (Read the full article)

There is a perception among clinicians that methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and/or meningitis result in a greater burden of disease than invasive infections attributed to methicillin-susceptible Staphylococcus aureus (MSSA) among very low birth weight (VLBW) infants.

VLBW infants with MRSA and MSSA bacteremia and/or meningitis have equivalent morbidity and mortality. These findings suggest that allocation of resources for prevention and treatment of both MRSA and MSSA infections among VLBW infants should be comparable. (Read the full article)

Prenatal methamphetamine exposure has been related to deficits in fetal growth, changes in infant neurobehavior, and fine motor deficits, but little is known about its developmental effects on behavior problems in early childhood.

This is the first prospective study to identify behavior problems associated with prenatal methamphetamine exposure. Mood difficulties and acting-out behavior are increased in exposed children by age 3 years. Early identification and intervention may prevent escalation into delinquency and psychopathology.

Subjects born preterm have higher blood pressure (BP) in childhood and adolescence. Little is known about at what age the deviation from normal BP starts, and data are especially scarce for the new generation of survivors after extremely preterm birth.

In a population-based study, we found that BP was higher in 2.5-year-old children born extremely preterm compared with controls. This finding might have implications for follow-up programs after preterm birth, with the goal of improving later cardiovascular health. (Read the full article)

As a result of safety and environmental concerns about mercury, aneroid sphygmomanometers have replaced mercury-filled devices for blood pressure measurements. Despite this change, few studies have compared the 2 devices.

Little clinical variation exists between blood pressure measurements obtained from an aneroid or mercury device, suggesting that either device could be used in a research or clinical setting. (Read the full article)

Although several randomized trials have examined the efficacy of serotonin receptor inhibitors in the treatment of repetitive behaviors, there still remains clinical uncertainty as to whether these agents are effective in treating such behaviors in children and adults with autism spectrum disorders.

The goal of this meta-analysis was to examine randomized trials of serotonin receptor inhibitors for treating repetitive behaviors in autism spectrum disorders. Although a small but significant effect of these agents was observed, this effect is likely due to the selective publication of trial results. (Read the full article)

Existing clinical research policy does not guarantee availability of results. Registration on the Web site ClinicalTrials.gov and the Food and Drug Administration Amendments Act improved transparency in pediatric clinical research. Registration and publication remain voluntary for many trials involving children.

Only 29% of completed registered studies and 53% of National Institutes of Health–funded trials involving children were published. Numbers of studies are increasing. Registration and posting of results on ClinicalTrials.gov should be mandatory for all studies involving children. (Read the full article)

Omega-3 fatty acids (O3FA) are commonly used as complementary treatments in pediatric psychiatric disorders, including Tourette’s disorder (TD), and are well known to have anti-inflammatory properties. However, no studies to date have examined the effects of O3FA on pediatric TD.

This is the first double-blind, placebo-controlled clinical trial of O3FA in pediatric TD. The results indicate that O3FA supplementation may be beneficial in the reduction of tic-related impairment for some children and adolescents with TD, but not tics per se. (Read the full article)

Some researchers have suggested that individuals with Down syndrome (DS) are protected from atherosclerotic disease; however, recent data from 2 large cohort studies of individuals with DS are significant for increased mortality from ischemic heart disease and cerebrovascular disease.

This study compares lipid profiles among children with DS and their siblings, highlighting the presence of a less favorable lipid profile in this high-risk population. (Read the full article)

Although obesity is correlated with levels of systolic and diastolic blood pressure, there is little evidence if the increases in obesity over the last 40 years have resulted in increased blood pressure levels.

Despite increases in obesity in Bogalusa, Louisiana between 1974 and 1993, there was no increase in systolic or diastolic blood pressure levels. It should not be assumed that trends in high blood pressure have paralleled those for obesity. (Read the full article)

Chronic fatigue syndrome (CFS) is a disabling illness. Some children with chronic disabling fatigue are housebound. Some primary care physicians find making the diagnosis of CFS difficult.

Chronic disabling fatigue is more common in 13-year-olds than previously realized with a population prevalence of ~2.0%. Chronic disabling fatigue in teenagers is more common in those with higher levels of early family adversity. (Read the full article)

Emphasis on preventing central line-associated bloodstream infections (CLABSIs) in US health care facilities and prophylactic antifungal medication use in neonates may impact incidence of Candida spp. CLABSIs. However, data on trends in incidence of neonatal Candida spp. CLABSIs are lacking.

Data from a large sample of US NICUs was analyzed to assess trends in incidence over time. This analysis provides a description of the epidemiology of Candida spp. CLABSIs in a national health care-associated infections surveillance system. (Read the full article)

Childhood abuse has been associated with obesity risk in adulthood. Little is known regarding the impact of abuse severity on risk, potential mechanisms are poorly understood, and few studies have been conducted among minority populations.

Severity of child/teenager physical and sexual abuse is associated with increased risk for adult obesity and/or central adiposity in adulthood. These are the first such findings in a large cohort of US black women. (Read the full article)

Siblings and other contacts of abused children, especially twins, are thought to be at higher risk for abuse than other children. However, the rate at which screening tests identify injuries in contacts is currently unknown.

Contacts of abused children with serious injuries have fractures identified on skeletal survey at significant rates. Twins are at substantially increased risk for fracture. Physical examination findings were not sensitive for fractures. (Read the full article)

In humans, evidence for an association between maternal caffeine intake during pregnancy and alterations in fetal brain development with persistent alterations in the offspring’s brain and behavior in later life is inconclusive.

Prenatal caffeine intake is not associated with a higher risk for behavior problems in young children. Results do not provide evidence to advise pregnant women to reduce their caffeine intake to prevent problem behavior in their children. (Read the full article)

Children with obstructive sleep apnea (OSA) are usually treated by surgical removal of their upper airway lymphadenoid tissue. Recently, medications were offered to patients with nonsevere OSA. Montelukast, for this indication, had never been studied in a randomized controlled manner.

Montelukast effectively reduced polysomnographic findings, symptoms, and the size of the adenoidal tissue in children with nonsevere OSA. The findings support the potential of a leukotriene modifier as a novel, safe, noninvasive alternative for children with mild to moderate OSA. (Read the full article)

Honey is recommended as a cough medication by the World Health Organization. To date, the efficacy of this treatment has been shown in 2 studies: one tested only buckwheat honey and the other study was not blinded.

In a randomized controlled trial, we compared 3 types of honey versus placebo as a treatment of upper respiratory tract infection–associated cough. These types of honey were superior to placebo in alleviating cough. (Read the full article)

Cholestasis predisposes to the development of fat-soluble vitamin (FSV) deficiency. D-α tocopheryl polyethylene glycol-1000 succinate and coadministered FSVs are absorbed in spite of cholestasis.

Infants with biliary atresia with total bilirubin >2 mg/dL are at risk for fat-soluble vitamin (FSV) deficiency. A multivitamin preparation containing d-α tocopheryl polyethylene glycol-1000 succinate alone is not effective in treating biochemical FSV insufficiency in cholestatic infants. (Read the full article)

Birth defects are associated with preterm birth and are a major contributor to infant mortality. There are persistent black-white differences in overall infant mortality and infant mortality attributable to birth defects.

Among infants delivered at 37 to 44 weeks, blacks and Hispanics had significantly higher neonatal and postneonatal mortality attributable to birth defects than whites. Among infants delivered at 20 to 33 or 34 to 36 weeks, neonatal mortality attributable to birth defects was significantly lower among blacks. (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)

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)

High blood pressure in childhood predisposes people to hypertension in adulthood and is associated with early development of cardiovascular disease and risk for premature death. High sodium intake and overweight/obesity are recognized as risk factors for hypertension in children.

These results show that usual sodium intake was positively associated with systolic blood pressure and risk for pre-high blood pressure and high blood pressure among US children. The data indicate a synergistic interaction between sodium intake and weight status on risk for high blood pressure. (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.

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)

Newborn screening is often seen as a fait accompli, even in programs that ostensibly proceed on the basis of informed choice and parental consent.

The study reports details of parental understanding, perceived ability to make an informed choice, and the availability of choice together with variables predictive of parental assessments of having made an informed choice. (Read the full article)

A previous study of inflatable bouncer–related fractures has shown that upper extremity fractures are most common, and many fractures are caused by collisions; however, no study has examined nonfracture injuries or used nationally representative data to investigate inflatable bouncer–related injuries.

This is the first study to use nationally representative data to calculate national injury rates, assess risk factors, and examine trends for pediatric inflatable bouncer–related injuries treated in US emergency departments over a 21-year period (1990–2010). (Read the full article)

Prenatal cocaine exposure is associated with the trajectories of childhood behavior problems. Exposure effects may also be related to maternal use of other substances during pregnancy, and risk factors other than prenatal exposure may augment the detrimental cocaine effects.

The balance between cumulative risk and protective indexes predicts behavior outcomes, independent of prenatal drug exposure. A high protective index even with a high level of risks can mitigate the detrimental effects of drug exposure on behavior problem trajectory. (Read the full article)

Most observational studies from Western populations suggest that blood pressure is positively associated with low birth weight and faster infant growth; however, it is unclear whether these associations are biologically based or contextually specific.

In a developed non-Western setting with relatively little socioeconomic patterning of size or growth, birth weight and infant growth had relatively limited impacts on early adolescent blood pressure, which was more strongly related to recent growth and current size. (Read the full article)

The eating of non–nutrient dense snack foods is considered a major factor contributing to childhood obesity. Parents are often ineffective at encouraging healthier snacking habits.

Children consumed fewer calories when snacking on nutrient-rich cheese and vegetables compared with when they were served potato chips. (Read the full article)

When research involving children is determined to present greater than minimal risk but no potential for direct benefit, permission is required from both parents, unless one is not reasonably available. These requirements are variably understood and applied, and guidance is lacking.

In a study on newborn screening, a sizeable percentage of fathers were not reasonably available, reflecting complexities of parental status and family relations. Guidelines developed in this project may provide tools for researchers and institutions to apply in other contexts. (Read the full article)

Part C early intervention serves ~2.8% of US children who are younger than 3 years old; however, there is evidence that substantial numbers of infants and toddlers with developmental delays receive no early intervention services.

Broad eligibility criteria can classify children who have no delays or minimal delays as candidates for Part C services. Despite this, no jurisdiction provides Part C services to all children who have substantial delays. (Read the full article)

Bronchiolitis, a leading cause of infant hospitalization, has few proven treatments. A few small studies have reported the beneficial effects of a mixture of 21% oxygen + 79% helium (Heliox). The 2010 Cochrane Review concluded that additional large randomized controlled trials were needed to determine the therapeutic role of Heliox in bronchiolitis.

The Bronchiolitis Randomized Controlled Trial Emergency-Assisted Therapy with Heliox—An Evaluation (BREATHE) trial is the largest multicenter randomized controlled trial to date to investigate the efficacy of Heliox in acute bronchiolitis. The delivery method for Heliox therapy was found to be crucial to its efficacy. (Read the full article)

Studies reveal that mothers of infants with colic (defined by Wessel’s criteria of >3 hours per day of distress) are more likely to develop depression. No studies have examined whether the consolability of infant crying predicts maternal depression risk.

Prolonged inconsolable infant crying has a stronger association with maternal depressive symptoms than overall daily duration of fussing and crying, suggesting that a mother’s report of inability to soothe her infant may be a powerful indicator of her depression risk. (Read the full article)

Blood lead levels well below 10 µg/dL are now recognized as causing adverse cognitive effects, including lower scores on standardized reading and math tests.

This is the first study to show that reading readiness early in kindergarten is independently associated with blood lead levels well below 10 µg/dL. Results suggest that lead exposure may have a larger impact on urban education than national estimates suggest. (Read the full article)

Self-medication with antibiotics available without prescription is among the main causes of antibiotic misuse in the developing world and is associated with antibiotic resistance. Inappropriate antibiotic prescription is common in children. Patient expectations seem to influence physicians’ advice.

This study demonstrates that even in places where antibiotics are unregulated, improving physician prescribing habits could reduce irrational use overall and also future caregiver-driven misuse. Physician training in adequate antibiotic prescription could be a cost-effective intervention in these settings. (Read the full article)

Elevated blood pressure (BP) has long-term influence on the atherosclerotic process. The relative predictive ability of the standard BP definition endorsed by the National High Blood Pressure Education Program and the recently proposed 2 simplified definitions has not been studied.

Simplified pediatric BP tables predict risk of high adult arterial stiffness as well as the complex table does. These simple screening tools could be used for identifying pediatric subjects at risk and for intervening to improve adult cardiovascular outcomes. (Read the full article)

Cognitive and behavioral problems after pediatric traumatic brain injury lead to poor functioning across multiple settings and can persist long-term after injury. Executive dysfunction is particularly common; however, there is a paucity of evidence-based interventions to guide treatment.

This study is among the largest randomized controlled trials performed in pediatric traumatic brain injury. It demonstrates the ability to use an online problem-solving-based intervention to improve caregiver ratings of executive dysfunction within 12 months after injury. (Read the full article)

Uric acid (UA) is associated with hypertension in children, after body weight adjustment. Whether the whole spectrum of variables, such as visceral adiposity, insulin resistance, puberty, and renal function, influence the relationship between UA and blood pressure is unknown.

In a cohort of children at relatively high cardiovascular risk, the association between UA and blood pressure levels is independent of several well-known factors implicated in the development of hypertension, such as insulin resistance, pubertal status, and renal function. (Read the full article)

Popular press and research show that sibling aggression is common. Too often, however, it is dismissed as benign, and other forms of child aggression, such as peer aggression, are considered more serious. Peer aggression is linked to poorer mental health.

Using a national probability sample, we show that the nature and severity of sibling aggression have negative links to children’s and adolescents’ mental health. We demonstrate that sibling and peer aggression are comparable their links to symptoms of distress. (Read the full article)

Screening for hypertension in asymptomatic children and adolescents occurs during routine care. For those with elevated blood pressure, a repeat measurement within 1 to 2 weeks is recommended. However, little is known about patterns of care after an incident elevated blood pressure.

In a population of 72 625 children and adolescents, 6108 (8.4%) had an incident elevated blood pressure. Among these, 1275 (20.9%) had their blood pressure measurement repeated within 1 month. However, few individuals with an incident elevated blood pressure subsequently developed hypertension. (Read the full article)

The evaluation of blunt head trauma in children who undergo cranial computed tomography will occasionally reveal incidental findings. These findings may require further evaluation or intervention. The prevalence of incidental findings has previously been described using small cohorts, limiting generalizability.

This study is the largest pediatric multicenter description of the prevalence of incidental findings on cranial computed tomography. Incidental findings are categorized by urgency to describe the spectrum of abnormalities, providing a context for clinicians faced with these unexpected results. (Read the full article)

Previous research on potential deleterious effects of typically developing children growing up in households with children with disability has produced mixed results. Research methods have been cited as a problem in many studies.

This is the largest known empirical study comparing functional impairment in siblings living with a child with disability and siblings residing with children who are typically developing. This study also follows the trajectory of functional impairment across 2 measurement periods. (Read the full article)

Blood cultures are a common investigation in children admitted to the hospital with skin and soft tissue infections. The yield of blood cultures in this condition is unknown.

Blood cultures are not useful in children admitted to the hospital with uncomplicated skin and soft tissue infections, and they may be associated with increased length of hospital stay. (Read the full article)

Effective implementation of Pediatric Emergency Care Applied Research Network head trauma rules depends on their early application. As the registered nurse (RN) is often the first to evaluate children with blunt head trauma, initial RN assessments will be an important component of this strategy.

We demonstrated fair to moderate agreement between RN and physician providers in the application of the Pediatric Emergency Care Applied Research Network head trauma rules. Effective implementation strategies may require physician verification of RN predictor assessments before computed tomography decision-making. (Read the full article)

Early timing of puberty and affiliation with deviant friends are associated with higher levels of delinquent and aggressive behavior. Early-maturing adolescents tend to affiliate with more-deviant peers and appear more susceptible to negative peer influences.

Young early-maturing girls do not yet associate with deviant friends but are more susceptible to negative peer influences. Early puberty effects are stable over time for delinquency but dissipate for aggression. Most of these relationships are invariant across race/ethnicity. (Read the full article)

Inconsistent results have been reported on the association between sleep duration and blood pressure (BP) in children, likely as a result of inadequate adjustment for confounders and the use of different time frames in assessing sleep duration.

Short sleep duration and poor sleep quality are associated with higher BP in normal-weight adolescents. One night of adequate sleep may partially ameliorate the risk of high BP but cannot completely reverse the effect of chronic sleep insufficiency. (Read the full article)

Currently, the false-positive rate of appendicitis in children is ≤5%. Abdominal imaging and blood tests (particularly leukocytosis) help minimize the negative appendectomy rate, but appendicitis is not always associated with an elevated white blood cell count.

Reducing the threshold of leukocytosis as a criterion for appendicitis to 8000 to 9000 white blood cells per µL improves specificity (negative appendectomy: <1%) while only marginally decreasing sensitivity. (Read the full article)

Preterm infants are at an increased risk of regulatory difficulties during infancy and of behavioral problems in childhood. In the full-term population, persistent crying problems that last beyond 3 months of age have been related to later behavioral problems.

Excessive crying by a preterm infant may reflect an increased risk for later behavioral problems and higher parenting stress even years later. Therefore, it is clinically relevant to assess systematically the crying behavior of preterm infants. (Read the full article)

Infant sleep and crying problems are common and associated with postnatal depression. No programs aiming to prevent all 3 issues have been rigorously evaluated.

A prevention program targeting these issues improves caregiver mental health, behaviors, and cognitions around infant sleep. Implementation at a population level may be best restricted to infants who are frequent feeders because they experience fewer crying and daytime sleep problems. (Read the full article)
