Exemption rates for immunization requirements have until recently been stable in states permitting religious exemptions. States with easy exemption processes have seen higher rates of vaccine-preventable diseases.

In New York, the rate of religious exemptions has increased. Counties with higher rates of exemption have a greater incidence of pertussis. (Read the full article)

The remarkable improvement in the survival of extremely premature infants has been well documented. However, there have been few cohort studies large enough to determine the neurodevelopmental outcomes of survivors born at 22 or 23 weeks.

The proportions of unimpaired or minimally impaired were 12.0% at 22 weeks (n = 75) and 20.0% at 23 weeks (n = 245). The outcomes were inferior compared with those for infants born at 24 and 25 weeks, but were improved compared with those in previous studies. (Read the full article)

Atherosclerotic cardiovascular diseases are rooted in childhood. Vascular intima-media thickness (IMT) and elasticity are early surrogate markers of atherosclerosis. In adults, cardiorespiratory fitness is associated with enhanced arterial elasticity and decreased IMT.

Fitness was favorably associated with aortic IMT and elasticity in adolescents. The association was independent of several cardiometabolic risk factors. In fit adolescents, the increase in IMT during the preceding 6 years was smaller compared with low-fit peers. (Read the full article)

Pediatric palliative care (PC) can be beneficial to children with life-threatening conditions and their families by providing symptom management and control, sibling support, bereavement services, spiritual guidance, support in decision-making about limiting burdensome medical interventions, and advance directives.

Little is known about actual receipt of PC by dying children. This study compares characteristics of dying children by receipt of PC and highlights underserved patient groups who could be targeted to improve access. (Read the full article)

Although concussion is increasingly being diagnosed in the pediatric population, little is known about what factors lead to prolonged postconcussive symptoms in children. In particular, the effect of previous history of concussion on recovery from a repeat injury is unclear.

Children with a history of previous concussion, particularly recent or multiple concussions, are at increased risk for prolonged symptoms after concussion. This suggests that repeat concussion, particularly within a vulnerable time window, may lead to longer duration of symptoms. (Read the full article)

Seizure-related death, including sudden death, is a frightening prospect. In part because risk and prevention are poorly understood, neurologists tend to avoid discussions of sudden death with families and young patients.

Most deaths in children with epilepsy are not seizure related. Relative to the population, however, sudden and seizure-related deaths alone double overall mortality. In uncomplicated epilepsy, such deaths occur at rates comparable to individual leading causes of death in young people. (Read the full article)

The ideal management of children with vesicoureteral reflux (VUR) remains a source of debate. There is little evidence to support many of the current management practices for children with VUR who have had 1 or 2 urinary tract infections.

Baseline associations, including bladder and bowel dysfunction and imaging studies, from the largest randomized, controlled trial conducted to date aimed at assessing the value of antimicrobial prophylaxis in children with urinary tract infection and VUR are presented. (Read the full article)

Significant variation in the mortality of preterm infants has been observed among NICUs. Factors explaining this variation have been difficult to identify.

Sizable center differences in mortality exist, even among similarly sized NICUs in academic centers. Patient characteristics and center treatment rates explain some of the center effect, especially for the youngest infants, but a significant portion of these differences remains unexplained.

Health care professionals face problems managing obesity and often fail to follow guidelines for its management in practice. Only a few single-country reports are available describing delivery of primary care to children with obesity.

Nearly all primary pediatric care providers from 4 European countries recognize the importance of obesity in pediatric practice, but only half use BMI clinically, and many lack the confidence and the infrastructure needed for providing care to patients with obesity. (Read the full article)

Wrapping very preterm newborns in polyethylene bags in the delivery room reduces hypothermia on admission to the NICU, but many infants remain cold despite their use. Placing polyethylene-wrapped infants on exothermic mattresses may reduce hypothermia but increase hyperthermia.

Placing polyethylene-wrapped very preterm infants on exothermic mattresses in the delivery room results in more infants with abnormal temperature and more hyperthermia on admission to the NICU. (Read the full article)

Feeding difficulties often emerge during the neonatal period and affect neonatal growth. Growth throughout the first years of life is associated with children’s IQ scores and risk of behavioral problems.

Among infants born full term (≥37 weeks’ gestation) with birth weight ≥2500 g, gain in weight and head circumference during the neonatal period is associated with higher IQ, but not with behavior at 6.5 years of age. (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)

Racial and ethnic differences exist in age at diagnosis and early access to mental and behavioral health services among children with autism spectrum disorders (ASDs). ASDs are also associated with increased rates of other medical comorbidities that may require specialty care.

Significant racial and ethnic differences in use of specialty care and specialty procedures exist among children with documented ASD. (Read the full article)

Obesity is associated with cardiometabolic risk factors and chronic conditions, such as type 2 diabetes. However, a proportion of overweight and obese youth remain free from cardiometabolic risk factors and are considered metabolically healthy.

This study provides insight into the determinants of cardiometabolic risk factors and the concept in health promotion of "fitness versus fatness." Hepatic lipid accumulation and not fitness level appears to drive cardiometabolic risk factor clustering among overweight and obese youth. (Read the full article)

Although unnecessary for children with headache and normal history, computed tomography (CT) scans are widely used. Fewer than 1% of pediatric brain abnormalities present with headache as the only symptom. Furthermore, repeated CT scans may increase lifetime risk of cancer.

CT scans continue to be used to diagnose isolated pediatric headaches despite existing practice parameters. Although emergency department visits were correlated with greater likelihood of CT scan use, these scans were widely used across a variety of clinical settings. (Read the full article)

Child maltreatment is a serious and prevalent public health problem in the United States. Responsible for substantial morbidity and mortality, maltreatment affects children's physical and mental health.

Although many health impacts of child maltreatment have been documented, no claims-based study has quantified the impact of maltreatment on health service utilization and costs. This study presents systematic claims-based estimates of maltreatment impacts on utilization and costs for the Medicaid population. (Read the full article)

Children with chronic pain complaints seem to represent an increasing portion of general pediatric inpatient services. Few data exist, however, on the characteristics of this population, their length of stay, or the best approach to their evaluation and management.

This study defines the demographic, diagnostic, procedural, and episode of care characteristics for children admitted to the acute care setting with chronic pain syndromes. Admission rates are rising, lengths of stay are substantial, and comorbid diagnoses are common. (Read the full article)

The incidence of necrotizing enterocolitis (NEC), a devastating condition in neonates, varies geographically and with time. Although the most consistent risk factors are prematurity and low birth weight, it has not been convincingly shown to increase in the postsurfactant era.

The incidence of NEC, especially among the highly premature but also in more mature groups, has increased in recent decades, concurrent with dramatically improved early infant survival. Seasonal variation of NEC suggests environmental etiological factors. (Read the full article)

Studies have highlighted a lack of patient awareness of potential increased cancer risks associated with computed tomography (CT) scans in adult patients and in nonurgent settings. However, little is known about parental awareness of these risks in an emergency setting.

Approximately half of parents were aware of the potential cancer risks from CT scans in an emergency setting. Although risk disclosure moderately reduced willingness to proceed with recommended testing, almost all parents preferred an informed discussion before CT imaging. (Read the full article)

Obstacles to vaccine delivery, including poverty, reduced access to medical care, and incomplete understanding of vaccine safety and importance, result in suboptimal coverage rates in some populations, allowing for disease outbreaks. Multicomponent interventions are successful in increasing immunization coverage rates.

We show that collaboration with local resources, including the county health department and a large community-based organization, effectively increases immunization coverage rates in low-income, resource-poor children. (Read the full article)

Prenatal diagnosis and clinical examination do not identify all infants with critical congenital heart defects before hospital discharge. To improve early critical congenital heart defect detection, New Jersey was the first state to implement legislatively mandated newborn pulse oximetry screening.

This report is the first to evaluate statewide pulse oximetry screening implementation. New Jersey had a high statewide screening rate and identified 3 infants with previously unsuspected critical congenital heart defects that otherwise might have resulted in significant morbidity and mortality.

Pain in children with cerebral palsy is underrecognized and undertreated and negatively affects quality of life. Communication challenges and multiple pain etiologies complicate management. There is a wide range of pain prevalence reported in the literature (14% to 73%).

The impact of pain on activities in children with cerebral palsy across a wide age range and motor abilities is investigated. Physician-identified causes of pain are systematically assessed and reported. Concordance of physician and caregiver identification of pain is evaluated. (Read the full article)

Several risk factors for both overweight and obesity in childhood are identifiable during infancy.

A simple risk algorithm can be used to quantify risk of overweight in children. It can be used to help identify at-risk infants in a clinical setting to facilitate targeted intervention. (Read the full article)

Many children exceed the American Academy of Pediatrics' recommendation to limit non-educational screen media to < 2 hours per day. The household media environment shapes children's television viewing (TVV), and heavy screen time is associated with poor health outcomes.

Parent TVV is a stronger predictor of child TVV than traditional media "access" and "rules" variables regardless of child age. This research highlights an important factor of child TVV that has been underemphasized in most studies and outreach efforts. (Read the full article)

Retinal hemorrhage (RH) is an important sign of pediatric abusive head trauma. Raised intracranial pressure (ICP) is sometimes proposed as an alternate cause of RH in children being evaluated for possible child abuse.

Nontraumatic, markedly elevated ICP rarely causes RH in children. When it does, RH are superficial intraretinal and located adjacent to a swollen optic nerve head. This pattern does not match the widespread pattern seen in abusive head trauma. (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)

The natural history of asthma during adolescence is dynamic because both remission and relapse are common. Remission has consistently been associated with mild asthma and the absence of sensitization.

One in 5 children with asthma remitted from age 7 to 19. Remission was defined as no wheezing and no medication for ≥3 years and was inversely related to female gender, sensitization to furred animals, and asthma severity at baseline. (Read the full article)

Twin studies suggest that bronchopulmonary dysplasia (BPD) is heritable; however, only a small number of genetic loci have been associated with BPD and these explain only a limited amount of this heritability.

A genome-wide association study of singleton infants (899 BPD cases and 827 controls) of 25 to 30 weeks’ gestational age did not identify single-nucleotide polymorphisms associated with BPD at the genome-wide significance level but did identify polymorphisms warranting further study. (Read the full article)

Respiratory support is commonly given to newborn infants via a face mask in the delivery room. Respiratory support given to preterm infants via a single nasal prong may be more effective.

Compared with a face mask, using a single nasal prong to deliver respiratory support to preterm newborns did not result in less intubation and ventilation in the delivery room. (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)

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)

Sugar-sweetened beverage (SSB) consumption in school-age children and adolescents is linked to heavier weight, and decreased SSB consumption results in less weight gain. Reports regarding these associations among children aged 2 to 5 years have been mixed.

Preschool-aged and kindergarten children drinking SSB compared with infrequent/nondrinkers had higher BMI z scores. SSB consumption is also associated with higher weight status among children aged 2 to 5 years. (Read the full article)

Critical congenital heart disease (CCHD) was recently added to the US Recommended Uniform Screening Panel for newborns.

Routine screening could cost an estimated additional $6.28 per newborn and $40 385 per life-year gained. The incremental cost of screening might be approximately $0.50 per newborn with reusable sensors. Future analysis of newborn screening programs may help refine these projections.

Data available before the 1990s in addition to small studies with clinical populations have shown that ocular growth and development differ between extremely preterm and term-born children.

Contemporary data on long-term visual outcomes indicate that adolescents born extremely low birth weight and/or extremely preterm exhibit more visual sensory and perceptual morbidity than adolescents born at term. (Read the full article)

Respiratory outcomes of patients with bronchopulmonary dysplasia (BPD) range from no oxygen requirement to chronic respiratory failure. Outcomes of least severe types of BPD are well described. Limited data exist on outcomes of patients with BPD-related chronic ventilator dependency.

Along with a first estimation of the incidence of patients with severe BPD-related chronic respiratory failure who were dependent on positive pressure ventilation via tracheostomy at home, we describe their survival rate, liberation from positive pressure ventilation, and decannulation. (Read the full article)

Bronchopulmonary dysplasia is associated with increased long-term neurodevelopmental and respiratory morbidity. Inhaled nitric oxide given to reduce morbidity in very preterm infants does not reduce the prevalence of bronchopulmonary dysplasia and has uncertain effects on long-term outcome.

Inhaled nitric oxide (5 ppm) given early in the course of respiratory illness in infants born before 29 weeks of gestation is not associated with changes in developmental or respiratory outcomes at 2 years of age corrected for prematurity. (Read the full article)

Newborns with critical congenital heart disease (CCHD) are at risk for cardiovascular collapse or death if discharged from the birth hospital without a diagnosis. Newborn screening aims to identify CCHD missed in prenatal and postnatal examinations.

Birth hospital nursery level and CCHD type were found to be associated with late CCHD detection. Routine newborn screening could conceivably reduce differences in the frequency of late diagnosis between birth hospital facilities. (Read the full article)

Preterm and low birth weight infants are at increased risk of hospitalization due to rotavirus gastroenteritis, and rotavirus vaccine is immunogenic and well tolerated among these infants when provided at or after discharge from the NICU.

Many preterm infants with a birth weight of ≤1500 g are not eligible to receive rotavirus vaccination because they remain in the NICU beyond the upper age limit recommended for immunization. New strategies are needed. (Read the full article)

The number of overweight and obese children has dramatically increased in recent decades. To combat this trend, information on possible gender-related differences in risk factors of overweight and obesity is critical.

This study examines associations of gender and physiologic and behavior measurements with potential cardiovascular risk. Lunch consumption and screen time were associated with weight; however, other associations with weight differ by gender. This information can be used to tailor future interventions.

Evaluating for elevations in alanine aminotransferase (ALT) is a common screening test for the presence of nonalcoholic fatty liver disease (NAFLD). NAFLD is less common among non-Hispanic blacks. Better predictors of NAFLD are needed to identify individuals in most need of screening.

Relative to other ethnicities, metabolic syndrome and insulin resistance performed poorly at identifying non-Hispanic black adolescents with ALT elevations. The presence of metabolic syndrome may therefore not be an adequate trigger for NAFLD screening. Triglyceride elevations performed similarly between groups in identifying ALT elevations.

Tympanometry provides a measure of middle ear function. There has been no description of the relationship between measurements of middle ear function in the absence of gross anatomic defects and clinical outcome among children with acute nontraumatic coma.

This study reveals an unexpected association between abnormal middle ear function and death in childhood acute coma. These findings call for more investigations on the relationship between middle and inner ear anatomy and function and intracranial dynamics and clinical outcomes. (Read the full article)

Studies examining the prevalence and associated features of autistic traits (ATs) in children with ADHD with exclusionary autism spectrum disorders suggest that children with ATs exhibit more severe social and interpersonal dysfunction reminiscent of the deficits in children with autism spectrum disorders.

Our results suggest that ATs are overrepresented in ADHD children when compared with control subjects. They also suggest that the presence of ATs is associated with more severe psychopathology as well as more impaired interpersonal, school, family, and cognitive functioning. (Read the full article)

Parents of premature infants are susceptible to developing trauma symptoms related to their NICU experience. There are no current well-established interventions that simultaneously address both parental trauma as well as redefinition of the parenting experience.

A brief, cost-effective, and feasible manualized intervention for NICU parents was effective in reducing both parental trauma and depression. Implementation of this intervention in the NICU setting has the potential to improve maternal well-being and infant outcomes. (Read the full article)

Persons with sickle cell anemia are known to have increased medical expenses, but little is known about the effects of hydroxyurea treatment on costs. In adults with severe sickle cell anemia, hydroxyurea has been reported to reduce expenses from hospitalization.

In this randomized placebo-controlled prospective multicenter trial of hydroxyurea in very young children with sickle cell anemia, not selected for severity, hydroxyurea was associated with significant medical cost savings due to a reduction in hospitalization expenses. (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)

Surviving infants with hypoxic ischemic encephalopathy (HIE) treated with hypothermia have decreased rates of CP in childhood. CP is associated with increased risk of slow growth.

Term children with HIE who develop moderate/severe CP are at high risk of progressive impaired growth, high rates of cognitive impairment, and rehospitalizations from infancy to school age. Gastrostomy tube placement to facilitate feeds is protective of slow growth. (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)

Health insurance is associated with improved health for children, but gay and lesbian parents face barriers to adding their children to private health insurance. Little is known about the extent to which insurance disparities exist for children with same-sex parents.

Children with same-sex parents are less likely to have private health insurance. When children live in states in which legal same-sex marriage, civil unions, domestic partnerships, or second-parent adoptions are available, disparities in private insurance diminish for children with same-sex parents.

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)
