Prenatal and postnatal organophosphate (cholinesterase inhibitor) pesticide exposure has been associated with delays in attention, memory, intelligence, and inhibitory control. Two recent studies reported decreased attention and working memory with greater exposure to organophosphates in boys but not in girls.

This is the first study to report associations between decreased acetylcholinesterase activity, a stable marker of cholinesterase inhibitor pesticide exposure, and lower overall neurodevelopment, attention, inhibitory control, and memory. These associations were present in boys but not in girls. (Read the full article)

Late-onset sepsis is a frequent complication of prematurity, contributing to morbidity and mortality. Although evidence is accumulating that administration of probiotics to very preterm infants reduces necrotizing enterocolitis (NEC) and all-cause mortality, the effect on late-onset sepsis is less clear.

The probiotic combination Bifidobacterium infantis, Streptococcus thermophilus, and Bifidobacterium lactis reduced NEC in very preterm infants, but not mortality or late-onset sepsis. Probiotics may be of greatest global value in neonatal settings with high rates of NEC. (Read the full article)

Children with autism spectrum disorders (ASD) or attention-deficit/hyperactivity disorder (ADHD) are at increased risk for sleep disturbances and excessive media use. However, the relationship between media use and sleep in children with ASD or ADHD has not been studied.

In-room access to screen-based media and video game hours were associated with less sleep among boys with ASD. The relationships between media use and sleep were much more pronounced among boys with ASD than among boys with ADHD or typical development. (Read the full article)

Although community engagement is considered an important professional role of physicians, there has been declining involvement of pediatricians in community child health activities. Whether enhanced training is associated with increased involvement is unclear.

This study reveals a continued decline in pediatricians’ involvement in community child health activities and is the first national study to identify a link between formal training and pediatricians’ community involvement. (Read the full article)

Preterm birth is associated with increased morbidity during childhood. Many studies have focused on outcomes for preterm births before 32 weeks’ gestation, but there are few follow-up data for late preterm infants (34–36 weeks’ gestation).

The risk of respiratory admission during childhood decreased with each successive week in gestation up to 40 to 42 weeks. The increased risk is small for late preterm infants, but the number affected is large and has an impact on health care services. (Read the full article)

Several studies have suggested that very low birth weight young adults have increased risks of physical and health problems, educational underachievement, and poorer social functioning than their peers, but there are limited population-based and longitudinal data.

Former VLBW young adults in this national cohort scored as well as term controls on many measures of health and social functioning, including quality-of-life scores, with some differences largely confined to those with disability at age 7 to 8 years. (Read the full article)

Adverse effects of excess weight are likely related to both obesity severity and duration. Little is known about the contribution of adolescent weight status to development of specific comorbid conditions in adults.

Severe obesity at age 18 was independently associated with increased risk of lower extremity venous edema, walking limitation, kidney dysfunction, polycystic ovary syndrome, respiratory conditions, diabetes, and hypertension in adulthood. (Read the full article)

Breast milk is protective against many conditions, but its role in allergy has not been established. Infant-feeding recommendations support exclusive breastfeeding for 26 weeks, whereas allergy prevention recommendations advise exclusive breastfeeding for 4 to 6 months with continued breastfeeding thereafter.

Evidence that continued breastfeeding while solids are introduced into the diet and delaying the introduction of solids until at least 17 weeks of age are associated with fewer food allergies. (Read the full article)

Few data on treating children hospitalized for influenza with neuraminidase inhibitors are available, contributing to uncertainty regarding the benefits of treatment.

This study of nearly 800 critically ill children suggests that treatment with neuraminidase inhibitors improves survival from influenza. This message needs additional emphasis, given that in the past 2 seasons over one-third of cases did not receive antiviral treatment. (Read the full article)

Socioeconomic status is known to influence health and health care utilization, but few studies have explored the relationship between community-level income and inpatient resource utilization for children.

In a large sample of pediatric hospitalizations, lower community-level household income is associated with higher inpatient costs of care for common conditions. These findings highlight the need to consider socioeconomic status in health care system design and reimbursement. (Read the full article)

Vaso-occlusive episodes (VOEs) are a common complication of sickle cell disease, resulting in morbidity. Magnesium is a vasodilator and has been shown to improve red blood cell hydration. Previous small studies have suggested that treatment with magnesium may decrease VOEs.

Intravenous magnesium sulfate is well tolerated in relatively high doses but had no effect on the length of stay in hospital, pain scores, or cumulative analgesia used in children admitted with painful VOEs in sickle cell disease. (Read the full article)

Screen time has risen to unprecedented levels among youth. Greater television time is known to be associated with gains in pediatric adiposity, but few studies have examined the longitudinal relations of other forms of screen-based media with weight gain.

Among adolescents aged 9 to 19 years, television viewing was the type of screen time most consistently associated with gains in BMI. However, time with digital versatile discs/videos and video/computer games was also associated with gains in BMI among girls. (Read the full article)

Abusive head trauma (AHT) is a rare phenomenon that results in devastating injuries to children. It is necessary to analyze large samples to examine changes in rates over time.

This is the first study to examine rates of AHT at the national, regional, and state level. The results provide a more detailed description of AHT trends than has been previously available. (Read the full article)

Pediatric surgery is performed in a variety of hospital types. General surgeons as well as fellowship-trained pediatric surgeons and surgical subspecialists perform inpatient operative procedures on infants and children. The distribution of procedures between specialists is not well characterized.

This study describes the demographics of pediatric surgery: the hospital type, the surgical procedures, and the quantity of inpatient pediatric surgery in the U.S. today. By implication, the data has much to inform health care about hospital and practitioner workforce. (Read the full article)

Medication errors occur frequently among pediatric patients, particularly those treated in rural emergency departments (EDs). Although telemedicine has been proposed as a potential solution, there are few data supporting its clinical effectiveness and its effect on medication errors.

The use of telemedicine to provide pediatric critical care consultations to rural EDs is associated with less frequent physician-related ED medication errors among seriously ill and injured children. Therefore, this model of care may improve patient safety in rural hospital EDs. (Read the full article)

One study examined the incidence of obesity among low-income children aged <5 years who participated in federally funded child health and nutrition programs during 1985–1990. The study examined the variations by baseline age but not by gender or race/ethnicity.

This study provides most recent data on incidence and reversing of obesity and variations across gender, baseline age, and racial/ethnic subgroups among young low-income children. We conducted multivariable analyses to examine the relative risk of obesity in population subgroups. (Read the full article)

Parents influence their child’s overweight development through lifestyle-related parenting practices. Although broader parenting dimensions may also affect children’s BMI, reverse causality is possible and there have been calls to examine the possible impacts of fathers.

More consistent parenting prospectively predicted lower child BMI with effects equally strong for fathers and mothers. There was little evidence of child BMI influencing parenting. Improved child BMI could be among the benefits of promoting parenting consistency of both parents. (Read the full article)

Attention-deficit/hyperactivity disorder (ADHD) is the most common mental health condition diagnosed in childhood, is highly heritable, and more common in boys. Although studies have identified perinatal risk factors, no one has investigated perinatal risk factors separately in boys and girls.

Contrary to other studies, low birth weight, postterm pregnancy, low Apgar scores, and fetal distress were not risk factors for ADHD irrespective of gender. Early term deliveries increased the risk of ADHD, and oxytocin augmentation in girls may be protective. (Read the full article)

Violence from school staff toward children is anecdotally widespread, but there are few empirical data on prevalence and health consequences, especially in low-income settings.

Despite a ban on corporal punishment, just over 52% of children in Luwero District experienced physical violence from school staff members in the previous week. This was associated with poor mental health in boys and girls and poor educational performance in girls. (Read the full article)

Bronchiolitis is a leading cause of hospitalization for children, yet variability in its management persists. To promote evidence-based care, the American Academy of Pediatrics published practice guidelines in 2006 that advocate primarily supportive care for this self-limited disease.

Since publication of the guidelines in 2006, few studies have evaluated their impact on diagnostic testing and treatment. This study documents positive changes in resource use among hospitalized patients with bronchiolitis over an 8-year period. (Read the full article)

Use of behavioral health (BH) screens in pediatrics have increased identification of children with BH issues. Screening rates increased in Massachusetts after it was mandated, as did the volume of some mental health services.

This is the first study of children after Massachusetts mandated behavioral screening began. Almost 40% of children who screened positive were newly identified. Being male, having a BH history, and being in foster care predicted a positive screen. (Read the full article)

The demand for donor kidneys for transplantation exceeds supply. En bloc kidney transplantation and donation after determination of circulatory death from pediatric donors increases the potential donor pool.

Newborn infants undergoing elective withdrawal of life support in the NICU are a previously unrecognized source of potential kidney donors. (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)

Increasing numbers of hospitals are instituting 24/7 in-hospital pediatric intensivist coverage. Data regarding patient outcomes are mixed and the impact on housestaff education remains unknown.

This study quantifies the perceived impact of in-hospital attending coverage on pediatric resident and critical care fellow education and also investigates the growing concern that increasing supervision may contribute to housestaff being less well prepared for independent clinical practice. (Read the full article)

Youth are frequent consumers of movies that contain high levels of violence, and violent content in films, especially those rated PG-13, has been increasing over time.

Content analyses seldom examine how violence is portrayed with other health risk behaviors, such smoking, drinking, and sex. This study presents an innovative way to characterize on-screen violent content and demonstrates the extent to which risk behaviors co-occur within films. (Read the full article)

Broad-spectrum antibiotics are frequently used to empirically treat children hospitalized with community-acquired pneumonia despite recent national recommendations to use narrow-spectrum antibiotics.

Narrow-spectrum antibiotics are similar to broad-spectrum antibiotics for the treatment of children hospitalized with community-acquired pneumonia in terms of clinical outcomes and resource utilization. This study provides scientific evidence to support national consensus guidelines. (Read the full article)

The emergency department (ED) is a critical contact location for youth violence interventions. Information on the characteristics of youth, motivations for fights leading to the injury, as well as previous health service utilization of assault-injured youth seeking care is lacking.

Assault-injured youth are characterized in a systematic sample demonstrating frequent ED use and the need to address substance use and lethal means of force in interventions; context and motivations for the fight are novel and will inform intervention efforts. (Read the full article)

Individuals with autism spectrum disorders have a higher comorbidity burden than the general pediatric population, including higher rates of seizures, psychiatric illness, and gastrointestinal disorders.

Comorbidities do not occur evenly. Our clustering analysis reveals subgroups characterized by seizure, psychiatric disorders, and complex multisystem disorders including auditory and gastrointestinal disorders. Correlations between seizure, psychiatric disorders, and gastrointestinal disorders are validated on a sample from a second hospital. (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)

Hypertonic saline (3% and 5%), has been shown to improve clinical severity scores and reduce inpatient length of stay, and was associated with a trend toward lower admission rate in acute bronchiolitis.

We are not aware of any previous data using 7% hypertonic saline in bronchiolitis. Our results suggest that 7% saline does not lower clinical severity of illness, admission rate, or length of stay, when compared with normal saline. (Read the full article)

Better postnatal growth, especially head growth, associates with better cognitive development in preterm infants. Suboptimal postnatal growth is more common in infants with poor antenatal growth than in infants with normal growth.

Good weight gain and head circumference growth until 2 years was associated with better 5-year cognitive outcome in non–small for gestational age infants. Good head circumference growth around term age benefits the cognitive outcome of small for gestational age infants. (Read the full article)

A serum 25-hydroxyvitamin D (25(OH)D) concentration of 20 ng/mL meets the requirements of at least 97.5% of the population older than 1 year. A recommended dietary intake to achieve this serum 25(OH)D concentration has not been established during infancy.

Daily maternal (during pregnancy) and then infant vitamin supplementation with 1000/400 IU or 2000/800 IU increases the proportion of infants with 25(OH)D ≥20 ng/mL during infancy with the higher dose sustaining this increase for longer. (Read the full article)

Fewer clinical trials are performed in children compared with other patient populations. It is unknown how well existing pediatric clinical trials are aligned with the needs of children, both in high-income countries and globally.

There is only moderate correlation between clinical trial activity and pediatric burden of disease, with certain conditions substantially underrepresented in the current research portfolio. Our findings provide a benchmark for prioritizing conditions for study, analyzing gaps, and identifying funding priorities. (Read the full article)

The incidence of pertussis has significantly increased, and infection can result in severe disease among young children. This highly contagious disease may frequently be transmitted in pediatric health care settings, necessitating effective infection control practices to reduce exposure risk.

Despite institutional guidelines, pediatric health care workers (HCWs) are frequently exposed to pertussis because of delayed or incomplete adherence to infection control practices. Inconsistent reporting may also result in missed HCW exposures, increasing the risk of subsequent transmission to patients. (Read the full article)

Saturations from pulse oximetry (SpO₂) may overestimate arterial oxygen saturations measured by CO-oximetry (SaO₂). The overestimation can be affected by location of measurement, perfusion, and skin color. Previous studies are limited by small numbers of observations in a hypoxemic range.

This large sample of hypoxemic patients identified that SpO₂ typically overestimates SaO₂. Bias and precision varied throughout the SpO₂ range. The SpO₂ range of 81% to 85% had the greatest bias: median SpO₂ 6% higher than SaO₂ measured by CO-oximetry. (Read the full article)

Studies assessing the accuracy of brief screening tools for postpartum depression have been conducted among adult women; however, no similar validation studies have been conducted among adolescent mothers. Accurate and valid brief depression screening tools are needed for adolescent mothers.

We found that the 10-item Edinburgh Postnatal Depression Scale (EPDS) and 2 subscales, the EPDS-7 and EPDS-2, are highly accurate at identifying postpartum depression among adolescent mothers. In pediatric settings with limited time and resources, these brief scales have potential to be used as effective depression screening tools. (Read the full article)

Although immunoglobulin replacement is recognized as effective in children with primary immunodeficiency, pneumococcal infection may occur. There is no available prospective clinical study evaluating levels of protective serospecific antibodies in patients and products.

Protective (0.2 µg/mL) antibody levels for the most frequent pneumococcal serotypes were measured in children treated for primary immunodeficiencies. A linear relationship was demonstrated between peak and trough levels of serospecific antipneumococcal antibodies in patients and infused immunoglobulins. (Read the full article)

The management of term and near-term newborns suspected of early-onset sepsis, particularly when they are not clearly symptomatic, remains controversial. Methods for quantifying risk that combine maternal factors with a newborn's evolving clinical examination have been lacking.

This study provides a method for predicting risk of early-onset sepsis. It combines maternal risk factors with objective measures of a newborn's clinical examination and places newborns into 3 risk groups (treat empirically, observe and evaluate, and continued observation). (Read the full article)

Early adiposity rebound is associated with future obesity and an increased risk of development of type 2 diabetes and coronary heart disease in adult life.

This study shows that early adiposity rebound is associated with future obesity and metabolic consequences of higher triglycerides, atherogenic index, apolipoprotein B, and blood pressure and lower high-density lipoprotein cholesterol at 12 years of age. (Read the full article)

Screening for autism spectrum disorders (ASDs) using the Modified Checklist for Autism in Toddlers (M-CHAT) improves early detection and long-term prognosis of ASD. Reducing the false-positive rate may increase implementation of screening for ASDs.

The Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F), simplifies wording of the original M-CHAT. The current validation study indicates that the M-CHAT-R/F improves the ability to detect autism spectrum disorders in toddlers screened during well-child care visits. (Read the full article)

Studies have shown dysfunction in the baroreflex mechanism and the autonomic nervous system, particularly in the sympathetic nervous system, in the pathophysiology of chronic fatigue syndrome, postural orthostatic tachycardia syndrome, and syncope.

Vitamin B₁₂ deficiency is associated with postural orthostatic tachycardia syndrome in adolescence. (Read the full article)

The sensitivities of ^99mTc-dimercaptosuccinic acid in predicting vesicoureteral reflux reported by different institutions were at different levels for young children with acute febrile urinary tract infection.

An acute ^99mTc-dimercaptosuccinic acid scan is of great value in predicting dilating vesicoureteral reflux in children ≤2 years of age with a febrile urinary tract infection. (Read the full article)

Payment arrangements that blend global budgets with pay-for-performance are proliferating. However, little is known about how these contracts affect pediatric health care quality and spending for children with and without special health care needs receiving care from large provider organizations.

A prototypical global budget contract significantly improved preventive care quality measures tied to pay-for-performance, especially for children with special health care needs. It did not alter trends for spending or for quality measures that were not tied to pay-for-performance. (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)

Bacille Calmette-Guerin (BCG) vaccination may provide benefits beyond protecting against pediatric tuberculosis. Evidence suggests links between cell-mediated immunity from tuberculosis and bacterial/viral-related pneumonia but the impact of BCG on acute lower respiratory infection is not fully known.

BCG-vaccinated children had a lower risk of suspected acute lower respiratory infection. Protection was amplified when children were vaccinated against diphtheria-tetanus-pertussis (DTP). Number of DTP doses did not modify this effect, but order in which vaccines were received did. (Read the full article)

Preterm infants dependent on parenteral nutrition are vulnerable to deficits in early postnatal nutritional intake. This coincides with a period of suboptimal head growth. Observational studies indicate that poor nutritional intake is associated with suboptimal head growth and neurodevelopmental outcome.

This study provides randomized controlled trial evidence that head growth failure in the first 4 weeks of life can be ameliorated with early nutritional intervention. Early macronutrient intake can be enhanced by optimizing a standardized, concentrated neonatal parenteral nutrition regimen. (Read the full article)

Cranial ultrasound is routinely used in identifying cerebral abnormalities in premature infants. Grade III and IV intraventricular hemorrhages, cystic periventricular leukomalacia, and late ventriculomegaly are all known predictors of adverse neurodevelopmental sequelae in these infants.

We reviewed neurodevelopmental outcomes among 2414 extreme preterm infants. Infants with grades I and II intraventricular hemorrhage had increased rates of neurosensory impairment, developmental delay, cerebral palsy, and deafness at 2 to 3 years’ corrected age. (Read the full article)

Systematic health disparities in adults with systemic lupus erythematosus are well documented and are likely driven by biologic as well as modifiable factors. Sociodemographic factors and health care delivery characteristics have been associated with poor outcomes.

In hospitalized children with systemic lupus erythematosus, race and ethnicity were associated with increased risk for ICU admissions, end-stage renal disease, and death. Identification of sociodemographic factors associated with outcomes is important to address the needs of these vulnerable patients. (Read the full article)

Although appendicitis is the most common surgical cause of abdominal pain in pediatrics, its diagnosis remains elusive. When evaluated independently, clinical scoring systems and ultrasonography have been shown to have low to moderate sensitivity in the diagnosis of appendicitis.

Our study evaluated the accuracy of a clinical practice guideline combining the Samuel’s pediatric appendicitis score and selective ultrasonography as the primary imaging modality for children with suspected appendicitis. Our clinical pathway demonstrated high sensitivity and specificity. (Read the full article)

Xylitol given as a gum or syrup 5 times daily has been shown to reduce the incidence of acute otitis media in children, but this dosing schedule is unlikely to be feasible for many families.

A regimen of viscous xylitol syrup in a dose of 5 g 3 times daily was ineffective in preventing recurrences of acute otitis media in otitis-prone children. (Read the full article)
