Sleep patterns of adult monozygotic twins are more similar than those of dizygotic twins, showing moderate heritability and little effects of environmental influences. There have been very few genetically informative studies of sleep in preschool children and results appear inconsistent.

From previous studies, we investigated daytime and nighttime continuous sleep duration longitudinally. This is the first time that the etiologies of daytime and nighttime continuous sleep duration trajectories were studied in early childhood. (Read the full article)

Excessive weight gain over the first 18 months of life may have consequences for later body size. However, the relationship of weight gain in this period to atherogenic risk factors in later childhood is not well characterized.

Early postnatal weight gain from birth to 18 months is independently associated with childhood overweight and obesity, excess central adiposity, and greater arterial wall thickness at age 8 years. (Read the full article)

Infants aged <2 months are at highest risk for pertussis morbidity and mortality but are too young to receive pertussis vaccines. To protect young infants, the Advisory Committee on Immunization Practices recommends mothers receive 1 dose of Tdap during pregnancy.

This article evaluates the effect of Tdap during pregnancy compared with postpartum Tdap and cocooning in preventing infant pertussis cases, hospitalizations, and deaths, as well as their relative cost-effectiveness. (Read the full article)

Infants with birth defects are more likely to be born preterm or with low birth weight and are at higher risk of death.

This study describes the prevalence of birth defects in a cohort of very low birth weight infants and evaluates in-hospital surgical procedures, morbidity, and mortality. (Read the full article)

Infants born late-preterm and early-term are at higher risk of morbidity and mortality compared with term infants. Home care practices recommended for all infants include supine sleep position, no smoke exposure, and breastfeeding to optimize health outcomes.

Our study provides new findings on the timing of hospital discharge, outpatient follow-up, and home care of late-preterm and early-term infants compared with term infants in the United States. (Read the full article)

Randomized controlled trials have shown that zinc supplementation during diarrhea substantially reduces the incidence and severity. However, the effect of short-course prophylactic zinc supplementation has been observed only in children >12 months of age.

The current study was able to show that short-course prophylactic zinc supplementation significantly reduced diarrhea morbidity in apparently healthy infants of 6 to 11 months even after 5 months of follow-up. (Read the full article)

The incidence of permanent hearing loss doubles between birth and school age. Otoacoustic emissions screening has been used successfully in early childhood educational settings to identify children with losses not found through newborn screening.

Using otoacoustic emissions to screen the hearing of young children during routine health care visits is feasible and can lead to the identification of permanent hearing loss overlooked by providers relying solely on subjective methods. (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)

Internet, smartphones, and online social media offer new platforms for health promotion and disease management. Few studies have evaluated the use of digital technology among families receiving care in an urban pediatric primary care setting.

Caregivers in an urban pediatric primary care setting have access to and frequently use the Internet, smartphones, and online social media. These technologies may help reach a traditionally hard-to-reach population. (Read the full article)

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

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

About one in five 2-year-olds are overweight, with potential adverse outcomes. Early feeding practices lay the foundation for food preferences and eating behavior and may contribute to future obesity risk. High-quality obesity prevention trials commencing in infancy are rare.

In this large randomized controlled trial, anticipatory guidance on the "when, what, and how" of complementary feeding was associated with increased maternal "protective" feeding practices. Differences in anthropometric indicators were in the expected direction but did not achieve statistical significance. (Read the full article)

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)

Preterm infants in the NICU receive the greatest number of transfusions of any patient population. The administration of the long-acting erythropoiesis stimulating agent (ESA) darbepoetin to reduce or eliminate transfusions in preterm infants has not been evaluated.

Infants receiving ESAs received half the number of transfusions and were exposed to approximately half the donors compared with the placebo group. More than half of the ESA recipients (59% darbepoetin recipients, 52% erythropoietin recipients) remained untransfused during their hospitalization. (Read the full article)

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

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

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)

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)

Young adult smokers frequently encounter the health care system as parents coming in for their child’s medical visit. Child health care clinicians, however, do not typically provide smoking cessation assistance to parents.

This national cluster-randomized trial demonstrates that a tobacco dependence intervention for parents can be effectively implemented in routine pediatric outpatient practice. (Read the full article)

Minority children are less likely than white children to be diagnosed and treated with attention-deficit/hyperactivity disorder. However, diagnosis patterns over time in early and middle childhood and whether confounding factors explain these disparities are not currently well understood.

Racial/ethnic disparities in attention-deficit/hyperactivity disorder diagnosis occur by kindergarten and continue until eighth grade. Racial/ethnic disparities among diagnosed children in medication use occur in both fifth and eighth grades. These disparities are not attributable to confounding factors. (Read the full article)

Infants born late preterm and early term are at increased risk for short-term morbidities compared with term infants. Longer-term morbidity and disability in this group of infants is not well established.

Massachusetts infants born late preterm and early term are at increased risk of early intervention program enrollment than term infants. Boys and children whose mothers were less educated, older, and with public insurance were most affected. (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)

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

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

Pneumococcal conjugate vaccines are effective in preventing pneumococcal disease but are also costly. Although the current US immunization schedule recommends 4 doses, many countries have adopted 3-dose schedules that have worked well, but may provide less protection against pneumococcal disease.

Changing the US 13-valent pneumococcal conjugate vaccine schedule from 3 to 2 primary doses while keeping a booster dose would save $412 million annually but might lead to moderate increases in pneumococcal disease, especially otitis media and pneumonia. (Read the full article)

Functional somatic symptoms (FSS) in children account for 10% to 15% of visits in medical services. Few studies have investigated the full range of pediatric FSS and factors linked to the medical help-seeking for young children with these symptoms.

More parental worries, higher symptom severity and impact, and previous contact to medical services are found among the children with FSS who seek medical consultation. Putative risk mechanisms include the early pattern of health care use and parental worries. (Read the full article)

Violence involving firearms is a leading cause of death among US youth ages 14 to 24. The emergency department is the primary medical setting for care of assault-injured youth and an underused but important setting for violence-prevention programs.

Among assault-injured youth seeking emergency department care, firearm possession rates are high, most obtained outside of legal channels. Higher rates of negative retaliatory attitudes and substance use among those youth with firearms increases risk of future lethal violence. (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)

Children exposed to alcohol prenatally have increased risk of a range of developmental problems such as language delay, behavior problems, learning, and memory and cognitive deficits, all of which can have a negative impact on educational achievement.

The expression of learning problems varied with the dose, pattern, and timing of prenatal alcohol exposure. Test scores below national benchmarks for reading were associated with first trimester heavy alcohol exposure and for writing after late pregnancy occasional binge drinking. (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)

Brief periods of low oxygen saturation are common in infants while restrained in car safety seats. There is some evidence that an insert that allows the infant head to rest in a neutral position in sleep may reduce hypoxic episodes.

This randomized controlled study shows that the insert reduced numbers of obstructive apneas and the severity of desaturation events but did not significantly reduce the overall rate of moderate desaturations. (Read the full article)

Physical punishment is associated with a range of Axis I and II mental disorders in adulthood. More research is needed on the possible long-term relationship between physical punishment and physical health.

To our knowledge, this is the first nationally representative examination of harsh physical punishment and physical health. Harsh physical punishment in the absence of child maltreatment is associated with higher odds of cardiovascular disease (borderline significance), arthritis, and obesity. (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)

There is wide variation in testing and treatment of children hospitalized with pneumonia. Limited data are available on diagnostic testing patterns and the association of test utilization with disposition outcomes for children with pneumonia evaluated in the emergency department (ED).

Significant variation exists in testing for pediatric pneumonia. EDs that use more testing have higher hospitalization rates. However, ED revisit rates were not significantly different between high- and low-utilizing EDs, suggesting an opportunity to reduce testing without negatively affecting outcomes.

Patients with hereditary angioedema (HAE) have recurrent episodes of painful swelling. Several new therapies to prevent and treat HAE attacks are approved by the Food and Drug Administration, but their safety and efficacy in children are largely unknown.

Ecallantide appears effective for treatment of HAE attacks in pediatric patients age 10 to 17 years with an acceptable safety profile. It represents a potential treatment option for adolescents with HAE. (Read the full article)

Assessment of general movements (GM) in early infancy is predictive of adverse neurologic outcome, particularly cerebral palsy. There is limited evidence of the predictive value of GM for other domains of neurodevelopment such as language and cognitive impairment.

Abnormal GM in preterm infants in the first 3 months postterm are predictive of a range of neurodevelopmental outcomes in early childhood. GM at 3 months are more accurate at distinguishing later neurodevelopment impairment than those at 1 month. (Read the full article)

Diabetic ketoacidosis (DKA) is a short-term complication of type 1 diabetes and is a major cause of preventable hospitalization in children. Hospital resource utilization and readmission rates for DKA across the US are not known.

Readmission for DKA within a year of hospitalization is common, accounting for one-fifth of all DKA admissions. Resource use, hospital length of stay, and readmission rates vary widely across major US children’s hospitals, even after adjusting for hospital differences in patients. (Read the full article)

Neonatal infections are frequent complications in very preterm infants, already at high risk of neurologic and cognitive disabilities. Few studies have linked neonatal infections and neurodevelopmental outcomes. Those that did evaluated children only to the age of 22 months.

This study assessed the respective effects of early- and late-onset sepsis and their association with 5-year neurodevelopmental outcomes. We identified a significant and cumulative risk of cerebral palsy when episodes of early- and late-onset sepsis were associated. (Read the full article)

Variation in the emergency department (ED) use of radiographs for asthma, bronchiolitis, and croup exists. Unnecessary radiographs contribute to higher costs of care, decreased ED efficiency, and increased radiation in children.

Despite no changes in guidelines to support routine use, there is a significant upward trend in the use of radiographs for children with emergency department visits for asthma. Pediatric-focused EDs use significantly fewer radiographs for asthma, bronchiolitis, and croup. (Read the full article)

In 2001, an estimated 10 438 children were treated in US emergency departments for nonfatal choking on food. The foods most frequently associated with pediatric fatal choking are hot dogs, seeds, nuts, candy, and certain types of fruits and vegetables.

From 2001 through 2009, an estimated annual average of 12 435 children ages 0 to 14 years were treated in US emergency departments for nonfatal choking on food; 0- to 4-year-olds accounted for 61.7% of episodes. Foods most frequently involved were candy, meat, bone, and fruits/vegetables. (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.

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.

Adolescents are likely to smoke if their parent(s) smoke. Little research uses prospective longitudinal data from parents and children to more confidently document these intergenerational associations, alongside potential confounders (parental education) and mediators (school achievement, mental health, older sibling smoking).

Analyses of long-term multigenerational data show how diverse parental smoking trajectories influence child smoking, controlling for measured confounders. The risk of smoking is especially high among children residing with a persistent heavy smoking parent and an older sibling who smokes. (Read the full article)

The diagnosis of urinary tract infection (UTI) is confirmed by urine testing with urinalysis and culture. No study has characterized the use of urine testing in the setting of empirical antibiotic prescription for outpatient UTI in children.

Urine tests are not performed in a substantial percentage of antibiotic-treated pediatric UTIs. Additional research is necessary to determine whether empirical antibiotic prescription for UTI in children without urine testing is safe and effective. (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.

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)
