This is the first population-based study regarding the epidemiologic characteristics of pediatric zoster among only those who had contracted varicella.

The herpes zoster (HZ) incidence among only children with varicella infection is higher than previously reported. The HZ incidence increased for children contracting varicella aged <2 years. After a vaccination program, the HZ risk increased for those contracting varicella aged ≥2 years. (Read the full article)

Although the rates of antipsychotic medication treatment are rising for children and adolescents, little is known about the factors associated with this practice.

This study provides some of the first data regarding when and why clinicians decide to use antipsychotic medications. It reveals clues as to how prescribing might better follow best practice guidelines. (Read the full article)

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

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

Early-life lower respiratory illnesses, including pneumonia, are associated with increased prevalence of asthma and diminished lung function in children. Whether early-life pneumonia is associated with subsequent impaired lung function and asthma in adults is not yet clear.

This is the first article providing strong data for an association between early-life pneumonia in an outpatient setting and airflow limitation and asthma into adulthood, supporting the hypothesis of the early-life origins of chronic obstructive pulmonary disease. (Read the full article)

Early language delay is common in toddlers and is associated with poor academic outcomes, reading difficulties, and persistent communication problems. Despite these long-term sequelae, few interventions for toddlers with early language delays yield positive expressive and receptive language results.

A 28-session program delivered over 3 months can enhance parent language facilitation strategies. Unusually, the small short-term benefits were mainly in receptive, rather than expressive, language and vocabulary. Extended follow-up could determine the costs versus benefits of this promising approach. (Read the full article)

Childhood bacteremia caused by vaccine-preventable organisms has substantially declined over the last decade. Recognition of bacteremia in children is difficult, and delayed administration of antibiotics is associated with poor outcomes. Adults with health care–associated Gram-negative bacteremia experience delays in receiving appropriate antibiotics.

Bacteremia in children presenting to the emergency department is increasingly health care associated and resistant to empirical antibiotics. These infections are associated with increased length of stay. Rates of Gram-negative bacteremia have increased, and children with Gram-negative bacteremia experience delayed antibiotic administration. (Read the full article)

Microvasculature alterations are associated with increased risk of hypertension in adults. Not much is known about the association of retinal vessel caliber with cardiovascular risk factors among children.

Narrower retinal arteriolar caliber is associated with higher blood pressure, mean arterial pressure, and pulse pressure in school-age children, whereas wider retinal venular caliber is associated with higher carotid-femoral pulse wave velocity. Microvascular adaptations might influence cardiovascular health from childhood onward. (Read the full article)

Acute kidney injury (AKI) occurs in up to 50% of children after cardiopulmonary bypass and is associated with adverse outcomes. Renal biomarkers have been shown to predict postoperative AKI, but few studies have examined cardiac biomarkers for risk classification.

Preoperative levels of creatine kinase-MB and heart-type fatty acid binding protein are strongly associated with the development of postoperative AKI after pediatric cardiac surgery and can be used to improve preoperative clinical risk prediction. (Read the full article)

The diversifying US population has led to the examination of workforce diversity and training. National data on diversity, inclusion, and cultural competency training have been previously collected but have been assessed only at the macro level of medicine.

This study assesses workforce diversity, inclusion, and cultural competency training in departments of pediatrics across the country and provides the first assessment of departmental efforts to improve diversity and inclusion and provide cultural competency training to trainees and faculty.

Strategies are needed to engage families of chronically ill children at home in an ongoing process of shared decision-making regarding treatment that is responsive to families’ concerns and goals and children’s evolving symptoms.

This study evaluated a novel patient portal that facilitates shared decision-making in asthma. The portal was feasible and acceptable to families, improved outcomes, and provides a model for improving care through an electronic health record portal. (Read the full article)

In a previous short-term physiologic randomized controlled trial, continuous positive airway pressure by helmet was feasible and efficient in improving gas exchange in pediatric acute respiratory failure due to bronchiolitis.

Continuous positive airway pressure administered by helmet reduces the rate of noninvasive respiratory support failure and provides longer application time with less sedation than a facial mask. In addition, it is safe to use and free from adverse events. (Read the full article)

Handheld echocardiography is a more portable and lower-cost alternative to standard echocardiography for rheumatic heart disease screening. Direct comparison of handheld echocardiography and auscultation for the detection of rheumatic heart disease has not been done previously.

Handheld echocardiography significantly improves detection of rheumatic heart disease compared with auscultation alone and may be a cost-effective screening strategy in developing countries. (Read the full article)

Functional capabilities in patients with spina bifida depend on the spinal level of the lesion and its type. Sociodemographic characteristics have been shown in other conditions to be an important additional influence on outcomes, making them important for risk adjustment.

Males, non-Hispanic blacks, and patients without private insurance have less favorable functional outcomes in spina bifida, and age also has an impact. These attributes need to be considered by clinicians and researchers and used in comparing care outcomes across clinic settings. (Read the full article)

Burns are a leading cause of pediatric emergency department visits and hospitalizations and are often associated with significant long-term physical and psychological consequences and long-term medical and nursing treatments. Little is known of the long-term impacts of burns on mortality.

Children with burns had a 1.6 times greater rate of long-term mortality than a matched population-based cohort of children with no injury. Total mortality burden based on in-hospital deaths alone underestimates the true burden from both minor and severe burns. (Read the full article)

Myxovirus resistance protein A (MxA) is a protein induced during viral infections. A few small-scale studies have suggested that MxA could be used as a marker of viral infection in clinical routine practice.

This study involves the largest patient population thus far and confirms the usefulness of MxA for diagnosing viral infections in children consulting the emergency department in a clinical routine setting. (Read the full article)

Encephalitis is a serious and disabling condition. There are infectious and immune-mediated causes of encephalitis, but many cases remain undiagnosed.

This large single-center study on childhood encephalitis provides insight into the relative frequency and clinicoradiologic phenotypes of infectious, autoantibody-associated, and unknown encephalitis. Risk factors for an abnormal outcome are also defined. (Read the full article)

Preterm children often experience poor executive function (EF; skills underpinning adaptive, goal-directed behavior, and essential for positive academic, occupational, and social outcomes). EF matures across adolescence, but the nature and course of EF deficits for preterm adolescents is not well-described.

Extremely preterm/extremely low birthweight adolescents demonstrated small-to-medium deficits across multiple EF domains compared with normal birthweight controls. Preterm children improved on some EF aspects from age 8 to late adolescence relative to controls, but not on parent-rated behavioral EF. (Read the full article)

Subtherapeutic doses of antibiotics have been used as growth promoters in animal farming since the 1950s. Antibiotic exposure during infancy is associated with increased body mass in humans.

The weight-promoting effect of antibiotics is most pronounced when the exposure occurs at <6 months of age or repeatedly during infancy. Increased body mass is distinctly associated with exposure to cephalosporins and macrolides, especially in boys. (Read the full article)

Childhood obesity rates in the United States remain at historic highs. The pediatric primary care office represents an important, underutilized source of intervention. There is a need to test the efficacy of motivational interviewing for pediatric obesity in primary care.

This is among the first large-scale randomized trials to show significant reductions in BMI and that motivational interviewing, delivered by trained providers in the primary care setting, can be an important and feasible part of addressing childhood obesity. (Read the full article)

Firearm violence is a leading cause of death among US youth aged 14 to 24. The emergency department is a key setting for interacting with high-risk assault-injured youth and remains an underused but important setting for violence prevention programs.

High-risk youth seeking emergency department care for assault have high rates of firearm violence over the subsequent 2 years. Higher severity substance use, combined with negative retaliatory attitudes and access to firearms, increases this risk for involvement with firearm violence. (Read the full article)

Although the psychometric properties of the school-age Strengths and Difficulties Questionnaire (SDQ) have been extensively examined by using longitudinal data, the preschool version of the SDQ has only been explored in a limited number of cross-sectional studies.

This is the first psychometric study of the preschool SDQ using longitudinal data. We report measurement invariance over time, satisfactory reliability, construct and criterion validity, and predictive utility for subsequent behavioral problems (4 years) and clinical disorders (2 years).

Pediatric residents may not be achieving competency in neonatal intubation. Opportunities for intubation during residency are decreasing. A precise definition of competency during training is lacking.

Bayesian statistics may be used to describe neonatal intubation competency in residents. At least 4 successful intubations are needed to achieve competency. The first 2 intubation opportunities appear to predict how many intubation opportunities are ultimately needed to achieve competency. (Read the full article)

Sharing human milk between those with an abundant supply and those seeking milk for their child is growing in popularity, including that facilitated by Web sites established to link buyers and sellers.

This study documents that human milk purchased via the Internet can be contaminated with cow’s milk, which poses a potential risk to infants with allergy or intolerance to cow’s milk. (Read the full article)

Trainee success rates with infant lumbar puncture are poor. The model of just-in-time learning via simulation has produced clinical improvement for other medical skills such as cardiac compressions and central line dressing changes.

This is the first study to evaluate the impact of just-in-time-and-place simulation-based learning on success with infant lumbar puncture. The intervention improved clinical behaviors associated with success without making a significant impact on success with the procedure. (Read the full article)

Although opioid pain relievers are commonly prescribed in pregnancy, their association with neonatal outcomes is not well described. Further, factors associated with development of neonatal abstinence syndrome, a neonatal opioid withdrawal syndrome is inadequately understood.

Prescription opioid use in pregnancy is common and strongly associated with neonatal complications. Antenatal cumulative prescription opioid exposure, opioid type, tobacco use, and selective serotonin reuptake inhibitor use increase the risk of neonatal abstinence syndrome. (Read the full article)

Children’s time with parents is critical for healthy development. Lack of control over parents’ schedules and limited supervisor support for personal and family life can interfere with parents’ family time.

This is the first group randomized controlled field trial demonstrating effects of a workplace intervention, designed to increase schedule control and supervisor support, on working parents’ time with their children, as assessed by using longitudinal daily telephone interviews. (Read the full article)

Early parenting programs benefit children’s development in low- and middle-income countries. However, the extent to which these interventions have a positive impact on parenting skills and their emotional availability is less studied.

An early child development intervention using play and communication activities to promote caregivers’ responsiveness can improve mother–child interactions, caregiving environment, caregiving practices pertaining to development and feeding, and, in combination with a nutrition intervention, support maternal emotional well-being.

Current childhood vaccination coverage rates among military dependents in the United States are not known. Past studies on childhood vaccination coverage in military dependents have shown mixed results, with the majority showing lower than ideal coverage rates.

This study analyzes a national database with 6 years of data and provider-confirmed vaccination status to describe the current documented vaccination coverage rates among military dependents in the United States. (Read the full article)

Although treatment of infection is a mainstay of neonatal intensive care, little attention has focused on the proportion of patient antibiotic exposures validated by clinical indications that are unambiguous.

Septic workups in 127 California NICUs reveal similar burdens of proven infection, yet patient antibiotic exposures in those NICUs vary 40-fold. Because antibiotic stewardship principles dictate that antibiotic use should correlate with burden of infection, some NICUs overuse antibiotics. (Read the full article)

Clinical trials of the quadrivalent human papillomavirus vaccine show it to be highly efficacious in preventing vaccine-type–specific cervical dysplasia and anogenital warts, but few studies have assessed its effects in the real world and none have done so at the program/population level.

This study provides strong evidence of the early benefits of quadrivalent human papillomavirus vaccination on reductions in cervical dysplasia and possible reductions in anogenital warts among girls aged 14 to 17 years, offering additional justification for not delaying vaccination until girls are older.

Disparities in asthma morbidity are exacerbated by underutilization of preventive controller medications. Community pharmacies are well positioned for an increased role in population health. The Asthma Medication Ratio, currently used at the patient-level, could be adapted for use at the pharmacy-level.

A newly developed Pharmacy-level Asthma Medication Ratio was associated with population-level childhood asthma morbidity. Collaborative relationships between physicians, community pharmacists, and patients (and families) have the potential to promote testable interventions aimed at reducing asthma morbidity and cross-community disparities.

Few studies have established the protective efficacy of 1 to 3 primary doses of diphtheria-tetanus-whole-cell pertussis (DTwP)/diphtheria-tetanus-acellular pertussis (DTaP) vaccines against pertussis, hospitalization, or pertussis complications in infants. However, vaccine effectiveness against infant pertussis death has not been previously reported.

This is the first study to report the protective role of ≥1 DTwP/DTaP doses among vaccine-eligible infants aged ≥6 weeks against death, hospitalization, and complications from pertussis. It describes risk markers for death among vaccine-ineligible infants aged <6 weeks. (Read the full article)

Concussion produces a range of symptoms that may impede academic functioning. The need for empirical validation exists, despite growing consensus on the importance of a guided return-to-school process for students recovering from concussion.

This study provides initial evidence of a concussion’s adverse effects on academic learning and performance across all grades, including heightened levels of school-related concern and amplified postinjury academic difficulties experienced by symptomatic students relative to their recovered peers.

Early detection of scoliosis facilitates treatment. For detection, topographic features, such as truncal asymmetry or rib hump, are used.

We show a correlation between curve magnitude at presentation and BMI. Obesity may obscure physical examination findings. (Read the full article)

Insulin resistance plays a role in obesity. Recently it has been associated with increased risk of AD. Aβ42 and PSEN1 are molecules associated with increased risk of later AD. Patients affected by AD show elevated levels of plasma Aβ42.

Levels of Aβ42 and PSEN1 are significantly elevated in obese adolescents and correlated with the degree of both adiposity and systemic insulin resistance. (Read the full article)

Care coordination is a central part of the medical home model. Little is known about how care coordination is implemented in pediatrics and how it changes over time in primary care practices successfully adopting medical home principles.

In high-performing medical homes, care coordination evolved toward designing and carrying out routine activities and policies that aimed to forestall disruptions in care delivery. Investing in medical home teams, engaging electronic medical record systems, and improving workflow supported these changes. (Read the full article)

The Respiratory Distress Assessment Instrument (RDAI) and the Respiratory Assessment Change Score (RACS) are the most frequently used measurement instruments in bronchiolitis clinical trials. Evidence is scarce regarding their measurement properties and their suitability for use as evaluative instruments in clinical trials.

The RDAI is an incomplete measure of respiratory distress in bronchiolitis, with poor to moderate construct validity. It has adequate discriminative properties but considerable test-retest measurement error. The RDAI and RACS were moderately responsive, but methodologic issues limit the interpretation of this finding. (Read the full article)

Evidence on the cardiometabolic consequences of sedentary behavior in youth is inconsistent and mostly relies on cross-sectional studies. Studies with objective measures of sedentary time have found limited evidence of cross-sectional associations with adiposity markers but no other outcomes.

Objectively assessed daily sedentary time was not prospectively associated with cardiometabolic outcomes. Moderate to vigorous physical activity was beneficially associated with body fat mass, insulin, high-density lipoprotein cholesterol, and clustered cardiometabolic score. (Read the full article)

Suboptimal brain development and increased risk of cognitive deficits are well documented in very low birth weight children. Supplementation with docosahexaenoic acid and arachidonic acid has been associated with positive cognitive effects.

This follow-up study of a randomized controlled trial of supplementation with docosahexaenoic acid and arachidonic acid to very low birth weight infants is the first report on both cognition and brain macrostructure measured with MRI. No cognitive or neuroanatomical effects were detected at 8 years. (Read the full article)

The sensitivity of the urinalysis (UA) traditionally has been considered suboptimal in young infants. Whether the finding of a negative UA and a positive urine culture represents a false-negative UA versus a false-positive urine culture remains unclear.

In infants <3 months with bacteremic urinary tract infection, a condition that represents true infection, the UA sensitivity is higher than previously reported for urinary tract infection in general, suggesting that the UA is reliable even in young infants. (Read the full article)

Youth drinking is associated with adult drinking. Alcohol policies can influence youth and adult drinking. However, it is unknown whether alcohol policies influence youth drinking patterns directly or through their effect on adult drinking.

Alcohol policies, including population-oriented policies, are protective for youth drinking. The effect of population-oriented policies may be mediated though effects on adults. These findings suggest that efforts to reduce youth drinking should rely on policies that address all age groups. (Read the full article)

Fifteen percent of tuberculosis cases globally are resistant to the drug isoniazid. Isoniazid resistance puts patients with tuberculosis at risk for poor treatment outcomes and threatens the effectiveness of isoniazid preventive therapy in people with latent tuberculosis infection.

We present the first global and regional estimates of the proportion of children with tuberculosis who have isoniazid-resistant disease, showing large geographic variations in risk of resistance. We estimate the number of annual incident cases of isoniazid-resistant tuberculosis in children. (Read the full article)

Most prospective cohort studies of acquired demyelinating syndromes in children have focused on the genetic, environmental, and neuroimaging predictors of multiple sclerosis. Less is known regarding the severity of the incident demyelinating event and predictors of residual attack–related physical disability.

In a national, prospective longitudinal study, incident acquired demyelinating syndromes in children were characterized in terms of physical deficits and acuity at onset, and recovery over the first 12 months. Follow-up evaluations up to 10 years’ postonset were analyzed. (Read the full article)

Clinical pain assessment methods in youth are vulnerable to underestimation bias and underrecognition. Facial expressions are sensitive, specific biomarkers of the presence and severity of pain. Computer vision–based pattern recognition enables measurement of pain-related facial expressions from video.

This study demonstrates initial validity for developing computer vision algorithms for automated pain assessment in children. The system developed and tested in this study could provide standardized, continuous, and valid patient monitoring that is potentially scalable. (Read the full article)

An increasing number of children are unvaccinated at entry into public schools, potentially endangering children who cannot be vaccinated for medical reasons and threatening herd immunity. Voluntary exemptions from immunizations vary geographically and by parental characteristics.

We find that exemption behavior is highest in peripheral areas of cities and that specific types of student populations are associated with high exemption rates. Additionally, there is spatial overlap between clusters of high personal exemption and medical exemption populations. (Read the full article)

Parental hesitancy about childhood vaccines is prevalent and related to delay or refusal of immunizations. Physicians are highly influential in parental vaccine decision-making, but may lack confidence in addressing parents’ vaccine concerns.

A physician-targeted communications intervention designed to reduce maternal vaccine hesitancy through the parent-physician relationship did not affect maternal hesitancy or physician confidence communicating with parents. Further research should determine the most effective approaches to addressing vaccine hesitancy. (Read the full article)

Pediatric patients suffer higher mortality due to the shortage of transplantable organs. Factors influencing families’ donation decisions are similar for pediatric and adult patients. However, the general perception that families of pediatric patients are less willing to donate persists.

Communication emerged as a critical factor of family authorization, reinforcing its importance in the organ donation process. Patient age (ie, adult versus pediatric) was not predictive of family authorization. (Read the full article)

Studies on the consequences of abnormal prenatal hemoglobin (Hb) concentration have focused on maternal morbidities and adverse birth outcomes. To date, very little is known about the association between prenatal Hb concentration and infant cognitive and motor functions.

There is an inverted U-shaped relationship between maternal Hb concentration and infant gross motor function. Hb concentration between 90 and 110 g/L appears to be optimal for early gross motor function of children. (Read the full article)

Vesicoureteral reflux is recognized as an important risk factor for recurrent urinary tract infection and renal scarring. Less is known about the contribution of other risk factors to these outcomes.

This study found that information about vesicoureteral reflux and bladder and bowel dysfunction can be used to identify children at low, medium, and high risk of recurrent urinary tract infection, information that clinicians could use to select children for specific preventive therapies.

"Protective" complementary feeding practices that promote self-regulation of intake and development of healthy food preferences have been positively associated with healthy child eating patterns and growth. There are few high-quality trials evaluating feeding practice interventions; none has reported long-term outcomes.

This large randomized controlled trial demonstrates that anticipatory guidance on the "how" of complementary feeding resulted in more protective feeding practices. These intervention effects were sustained for 3 years and translated into commensurate trends in obesity risk. (Read the full article)
