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)

Children with autism spectrum disorder (ASD) and those with ADHD are at risk for problematic video game use. However, group differences in media use or in the factors associated with problematic video game use have not been studied.

Boys with ASD and ADHD demonstrated greater problematic video game use than did boys with typical development. Inattention was uniquely associated with problematic use for both groups, and role-playing game genre was associated with problematic use among the ASD group only. (Read the full article)

Pulse oximetry screening at 24 hours of age improves detection of critical congenital heart disease in asymptomatic newborns.

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)

The incidence of pediatric pneumococcal meningitis has declined after introduction of the 7-valent pneumococcal conjugate vaccine (PCV7). It is unknown whether the frequency of severe neurologic sequelae and adverse outcomes has changed in the era of widespread PCV7 use.

Pneumococcal meningitis continues to be associated with substantial mortality and long-term morbidity. Sixty-three percent of survivors had neurologic sequelae. More than one-half of the children who were eligible for PCV7 were unimmunized at the time that they developed pneumococcal meningitis. (Read the full article)

Pulmonary embolism (PE) in the pediatric population is rare but does occur and is underrecognized. In adult emergency medicine, there are validated clinical decision rules derived to provide reliable and reproducible means of determining pretest probability of PE.

There are known risk factors, signs, and symptoms that should raise the clinician’s suspicion of pulmonary embolism, even in the pediatric population. (Read the full article)

Shared decision-making involves the assessment of preferences and goals and has been prioritized in new attention-deficit/hyperactivity disorder treatment guidelines, yet no studies have examined the impact of both preferences and goals on treatment initiation.

Supporting the clinical utility of preference and goal assessment, we found that parental treatment preferences are associated with treatment initiation, and those with distinct goals select different treatments. (Read the full article)

Rehabilitation of people with cerebral palsy aims to achieve and maintain optimal performance in mobility and daily activities. Although insight into the developmental trajectories of activities from childhood into adulthood is important, little is known about long-term development.

The gross motor function of children with cerebral palsy determines the developmental trajectories of mobility performance but not of daily activities, where intellectual disability was shown to be the determining factor. (Read the full article)

Pediatric early warning scores (PEWS) for hospital inpatients have been developed to identify patients at risk for deterioration. Beyond triage, similar systems that identify ill patients and predict requirements for a higher level of care are needed in the emergency department.

The validity of the different PEWS in pediatric emergency care patients has never been evaluated. This study showed that PEWS are capable of detecting children in need of ICU admission. (Read the full article)

Hypovitaminosis D is common among children. Although there is prolific biochemical literature linking vitamin D to enteric immunologic function, there is a paucity of prospective data exploring the role of supplementation in prevention of diarrheal illnesses.

In a high-risk population, quarterly supplementation with 100 000 IU of vitamin D₃ did not reduce the risk for first or recurrent diarrheal illnesses in a population of children aged 1 to 29 months in a low-income inner city setting. (Read the full article)

Several studies have suggested that probiotics may prevent necrotizing enterocolitis and death in preterm infants. However, there are no data on the preventive effect of probiotics in infants with cyanotic congenital heart disease.

Although duration of hospitalization was not significantly decreased, Bifidobacterium lactis plus inulin appears to decrease the rate of nosocomial infection, necrotizing enterocolitis, and death in infants with cyanotic congenital heart disease. (Read the full article)

Cross-sectional estimates suggest that one-third of children are enrolled in Medicaid or other public insurance programs. The percentage of children enrolled in Medicaid at any point during childhood, and which children use Medicaid as a longer-term insurance source, is unknown.

Over a 5-year period, 41% of children were enrolled in Medicaid at some point. Of those children, 51.5% were enrolled during all 5 years. Children with sociodemographic risk factors are more often enrolled for longer periods of childhood. (Read the full article)

Racial/ethnic differences in care for adult and pediatric patients in the emergency department have been documented.

This study reveals racial/ethnic differences in analgesic administration and prolonged length of stay for pediatric emergency department visits for abdominal pain. Documenting such disparities is an important first step needed to improve the equity of care for this and other conditions. (Read the full article)

More than 70% of all preterm deliveries are late-preterm (34–36 weeks of gestation). Compared with those born at term, those born late-preterm have higher risk for medical and neurodevelopmental disabilities and suffer more often from mental and behavioral problems.

Late-preterm birth is associated with considerable lifetime socioeconomic disadvantages across the adult years. These disadvantages are not explained by childhood parental socioeconomic position. (Read the full article)

Food marketing can lead to increases in food intake, purchase intentions, and brand preferences. Food companies use athlete endorsements as 1 form of food marketing. One study revealed that parents perceive athlete-endorsed food products as healthier than nonendorsed products.

This study assessed the (1) prevalence of athlete endorsements of food, (2) nutritional profile of foods endorsed by athletes, and (3) youth exposure to athlete endorsements of foods. This study reveals that adolescents saw more athlete-endorsement food commercials than adults. (Read the full article)

Use of complementary and alternative medicine (CAM) is increasingly common among American youth; however, information on use of CAM among youth with recurrent headache (HA) is limited.

Youth across a range of chronic conditions experience HA. These youth are more likely to use CAM. Use and expenditures for conventional medical care, and increased difficulties in activity and functioning are greater for youth with HA who use CAM. (Read the full article)

A large and growing literature has demonstrated significant associations between the use of spanking and later child aggression, but we know less about paternal spanking, effects of spanking on cognitive development, and longer-term effects.

Accounting for a broad array of risk factors, spanking predicts both aggression and receptive vocabulary across the first decade of life. Importantly, we include paternal spanking, cognitive outcomes, and a longitudinal span longer than that of much of the literature. (Read the full article)

Pertussis rates are on the rise in the United States. Infants often require hospitalization for pertussis. Vaccination can change hospitalization patterns for vaccine-preventable diseases. It is unknown if vaccinating adolescents for pertussis (recommended in 2006) might change infant hospitalization utilization.

Universal vaccination policy among adolescents against pertussis appears to have been effective in 3 of the 4 years we examined postvaccination. Further vaccination efforts among adolescents and adults are needed to prevent infantile hospitalization on a more consistent basis. (Read the full article)

Unintentional overdose and emergency department visits secondary to nonmedical use of prescription drugs are on the rise with peak age of onset in midadolescence for these risk behaviors. Also, risk behaviors, such as substance use and violence, tend to cluster.

Approximately 1 in 10 adolescents or young adults using the emergency department endorse nonmedical prescription opioid or sedative use in the past year. Rates of current opioid or sedative prescriptions are low among this group. (Read the full article)

Several studies have documented earlier onset of pubertal maturation in girls, with several potential factors attributed to the earlier onset.

This study demonstrates earlier maturation in white non-Hispanic girls, with greater BMI linked as a major factor. The entire distribution of pubertal timing has shifted to a younger age, suggesting redefinition of ages for both early and late maturation. (Read the full article)

Global health is of increasing interest and relevance to North American pediatric trainees. Opportunities for resident global health training and exposure are most often limited to electives or trainees in dedicated global health tracks.

A series of short, structured, participatory global child health modules improved knowledge and were well received and integrated within academic programs. Such modules enable global health learning for all residents, including those who never intend to practice overseas. (Read the full article)

Young age at first sexual intercourse (FSI) is related to risk-taking behaviors and negative outcomes. Previous studies using a cohort or cross-sectional design have concluded that younger age at menarche (AAM) is related to younger age at FSI.

This large birth cohort study is the first to address the temporal relationship between AAM and FSI. We found that younger AAM does not confer higher risk of early FSI, whether in terms of calendar age or time since menarche. (Read the full article)

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)

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)

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)

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)

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)

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)

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)

Due to reports of unintentional overdoses, in 2011 the US Food and Drug Administration finalized voluntary recommendations for dosing devices included with over-the-counter (OTC) liquid medications. The Consumer Healthcare Products Association previously endorsed similar recommendations for devices and dosing directions.

This study assessed dosing directions and devices for national brand name OTC liquid medications, available after a voluntary FDA guidance, and found high levels of adherence to most recommendations. Further improvement efforts should prioritize recommendations directly addressing potential dosing errors. (Read the full article)

Injuries sustained by children in the school setting have a significant public health impact. A concerning subgroup of school injuries are due to intentional and violent etiologies. Several studies have identified a need for further research to understand intentional school-based injuries.

This study discusses national estimates and trends over time and risk factors of intentional injury–related emergency department visits due to injuries sustained in the school setting. (Read the full article)

Recommended management of febrile neonates (≤28 days) includes blood, urine, and cerebrospinal fluid cultures with hospital admission for antibiotic therapy. No study has reported adherence to standard recommendations in the management of febrile neonates in US pediatric emergency departments.

There is wide variation in adherence to recommended management of febrile neonates. High rates of serious infections in admitted patients but low return rates for missed infections in discharged patients suggest additional studies needed to understand variation from current recommendations.

Children with congenital heart disease demonstrate a high prevalence of low-severity developmental problems in the areas of language, motor skills, attention, and executive function. Systematic evaluation has been recommended to promote early detection of problems and ensure appropriate intervention.

This study presents results of longitudinal testing in early childhood. Developmental delays were common. Feeding difficulty and medical and genetic comorbidities increased risk for delays. Exposure to risk and prevalence of delay change over time; therefore, repeated evaluations are warranted. (Read the full article)

It is known that adult language input is important to healthy language development and that preterm infants are at risk for language delay.

This is the first study to provide evidence that preterm infants’ exposure to adult words in the NICU before the mother’s due date are associated with better cognitive and language outcomes at 7 and 18 months’ corrected age. (Read the full article)

Although fertility rates among adolescents have declined in recent years, certain groups of adolescent girls remain at risk. Whereas adolescents with major mental illness have many risk factors for teenage pregnancy, their fertility rates have not been yet to be examined.

Fertility rates among adolescent girls with major mental illness are almost 3 times higher than among unaffected adolescents and are not decreasing to the same extent. Mental health considerations are highly important for pregnancy prevention and for perinatal interventions targeting adolescents. (Read the full article)

Income inequality is positively associated with several adverse child health and well-being outcomes. There is no existing research investigating the relationship between income inequality and child maltreatment rates.

This study is the first to demonstrate that increases in income inequality are associated with increases in child maltreatment rates at the county level. (Read the full article)

Despite widespread prevalence of vitamin D deficiency, there is a paucity of evidence on the appropriate supplemental dose in preterm infants. Various professional organizations empirically recommend different doses of vitamin D, ranging from 400 to 1000 IU per day.

Daily vitamin D supplementation at a dose of 800 IU compared with 400 IU significantly reduces the prevalence of vitamin D deficiency in preterm infants. The clinical significance of achieving vitamin D sufficiency needs to be studied in larger trials. (Read the full article)

Greater numbers of invasive procedures from birth to term-equivalent age, adjusted for clinical confounders, are associated with altered brain microstructure during neonatal care and poorer cognitive outcome at 18 months’ corrected age in children born very preterm.

Altered myelination at school age is associated with greater numbers of invasive procedures during hospitalization in very preterm children without severe brain injury or neurosensory impairment. Greater numbers of invasive procedures and altered brain microstructure interact to predict lower IQ. (Read the full article)

Although care coordination has been associated with lower health care costs and improved outcomes for vulnerable children, little is known about the extent of need and factors associated with unmet need for care coordination among children with mental health conditions.

Children with mental health conditions have substantial need and unmet need for care coordination. Unmet need is more likely for families with children with anxiety disorder and less likely for those who report social support and family-centered care. (Read the full article)

An estimated 9.5% of children are diagnosed with attention-deficit/hyperactivity disorder (ADHD), which affects academic and social outcomes. We previously found significant improvements in ADHD symptoms immediately after neurofeedback training at school.

This randomized controlled trial included a large sample of elementary school students with ADHD who received in-school computer attention training with neurofeedback or cognitive training. Students who received neurofeedback were reported to have fewer ADHD symptoms 6 months after the intervention. (Read the full article)

Prenatal lipid-based nutrient supplementation has been demonstrated to increase birth length. However, the impact of this intervention on infant growth and morbidity is unknown.

Infants from mothers who were given prenatal lipid-based nutrient supplements showed decelerated linear growth. The gain in length at birth related to prenatal lipid-based nutrient supplementation was not sustained during infancy. (Read the full article)

Recent studies have shown that participating in the Supplemental Nutrition Assistance Program (SNAP) is associated with improved household food security. With the exception of 1 descriptive analysis, studies have not examined how SNAP affects children’s food security.

This article estimates the association between SNAP and children’s food security using the largest, most rigorous national study of food security to date. Given current proposals to reduce program size, this study underscores SNAP’s importance in affecting children’s well-being. (Read the full article)

Concussions in youth are a common injury evaluated in the emergency department (ED). Early recognition and active management of this mild traumatic brain injury are important to safe recovery. Tools to assess and manage concussion in the ED are lacking.

Acute Concussion Evaluation tools, modified for ED use, improved reported follow-up with primary care or concussion specialists and adherence to recommendations. Barriers to follow-up remain and the importance of ongoing outpatient management should be stressed. (Read the full article)

The pediatric mental health burden is substantial, with >4 million children meeting criteria for a mental health disorder. Mental health is a key priority for national pediatric inpatient quality measures, but little is known about admitted patients and their diagnoses.

Nationally, nearly 10% of hospitalizations in children >3 years are for primary mental health diagnoses. The most common and costly are depression, bipolar disorder, and psychosis. Fewer free-standing children’s hospitalizations (3%) were for mental health admissions, although diagnostic distributions were similar. (Read the full article)

Preterm infants have transiently lowered thyroid hormone levels during the early postnatal period. Past research suggests that low thyroid hormone levels are related to cognitive and developmental deficits in children born preterm.

Contrary to expectations, in this study of children born <30 weeks’ gestation, higher concentrations of free thyroxine over the first 6 weeks of life were associated with poorer cognitive function at 7 years of age. (Read the full article)

Many studies have demonstrated that the built environment is related to both collision risk and walking to school. However, little research examines the influence of the built environment on the relationship between walking to school and pedestrian collision risk.

Increased walking was not associated with increased pedestrian collision once the effects of the built environment and socioeconomic status were modeled. Safety was related primarily to the built environment and specifically features related to road crossing. (Read the full article)

The use of electronic health record systems to measure adolescent health care quality requires an operational definition of sexual activity for measuring recommended health promotion activities such as Chlamydia screening and others related to reproductive health.

This study is the first to compare operational definitions of sexual activity by using information electronically abstracted from electronic health records of adolescent females. Our research supports the use of broader operational definitions of sexual activity for health quality measurement. (Read the full article)
