Infant postexposure prophylaxis prevents perinatal hepatitis B (HepB) virus transmission and mortality and morbidity caused by chronic HepB virus infection. The US Perinatal Hepatitis B Prevention Program (PHBPP) identifies and manages infants born to HepB surface antigen–positive women.

It presents the first estimates of the long-term costs and outcomes of postexposure prophylaxis with the PHBPP. It analyzes the effects of the PHBPP, and alternative immunization scenarios, on health and economic outcomes for the 2009 US birth cohort. (Read the full article)

Sending sexual messages and/or pictures (sexting) has been associated with sexual intercourse among high school–age students.

This study is the first to examine sexting’s prevalence among at-risk middle school students and its associations with a range of sexual behaviors. It also examines differences in sexual risk between sending sexual messages and sexual photos. (Read the full article)

Warnings of increased risk for suicidality have been placed on antidepressant medications. Because antidepressants differ in their characteristics, including effects on neurotransmitters, it is possible that the risk of suicidal behavior for individual medications may differ.

In a cohort of 36 842 children with review of medical records for confirmation of suicide attempts, we found no difference for risk of suicide attempts among individual medications compared with fluoxetine, the currently recommended antidepressant for treatment of depression.

Infant sleep and crying problems are common and associated with postnatal depression. No programs aiming to prevent all 3 issues have been rigorously evaluated.

A prevention program targeting these issues improves caregiver mental health, behaviors, and cognitions around infant sleep. Implementation at a population level may be best restricted to infants who are frequent feeders because they experience fewer crying and daytime sleep problems. (Read the full article)

Childhood obesity poses a serious threat to human health. Obesity is caused by genetic and environmental factors and linked to type 2 diabetes and cardiovascular disease. Pediatric obesity cohorts aim at understanding early events in the pathophysiology of obesity-related complications.

Cohort subjects are examined at consecutive visits, including measurements of glucose tolerance and hormones regulating nutrient handling (enhanced glucose tolerance tests) and body composition (MRI and bioimpedance). Mechanisms causing obese children to progress to type 2 diabetes are delineated. (Read the full article)

There is a perception that Gram-negative bacilli (GNB) bloodstream infection is increasing in the NICU, and those infections caused by a multidrug-resistant (MDR) strain are a growing threat to hospitalized patients.

Exposure to broad-spectrum antibiotics is the most important risk factor for MDR GNB bacteremia, which is associated with higher mortality. Neonates with risk factors for bacteremia caused by a MDR GNB strain may benefit from empirical antimicrobial therapy with carbapenem. (Read the full article)

Age-appropriate child safety seat use in the United States is suboptimal, particularly among children older than 1 year. Minority children have higher rates of inappropriate child safety seat use based on observational studies. Explanations for observed differences include socioeconomic factors.

White parents reported greater use of age-appropriate child safety seats for 1- to 7-year-old children than nonwhite parents. Race remained a significant predictor of age-appropriate restraint use after adjusting for parental education, family income, and information sources. (Read the full article)

Human rhinovirus has been known as the common cold agent. Recently, studies have reported that this virus is responsible for severe infections of the lower respiratory tract in children. Reports of factors that increase disease severity have been contradictory.

This study identifies some of the factors involved in disease severity in HRV infections in children. We expect that children at risk for developing severe disease could be identified sooner and appropriate measures could be taken. (Read the full article)

The effects of previous school-based physical activity promotion interventions have been modest, and none have demonstrated significant or meaningful increases in children’s physical activity outside of school, a period characterized by disproportionally low levels of physical activity in youth.

This study adds to the evidence-base for the effectiveness of comprehensive school health programs by demonstrating that such novel interventions lead to statistically significant, meaningful increases in the amount of physical activity children achieved on weekends and after school hours. (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)

Shoulder injuries are common among high school athletes. These injuries, both traumatic and overuse, contribute to significant time loss from athletic activity. Understanding sport-specific injury patterns is critical for development of targeted injury prevention programs.

This study is the most comprehensive analysis of high school shoulder injuries to date, providing national injury estimates while examining injury rates, diagnoses, severity, and mechanisms of injury in 9 interscholastic sports. (Read the full article)

Celiac disease (CD) often goes undiagnosed. Current guidelines suggest intensified active case-finding, with liberal testing of children with CD-associated symptoms and/or conditions. However, methods for also finding undiagnosed CD cases in the general population should be explored and evaluated.

In a population-based CD screening, information on CD-associated symptoms and conditions, obtained before knowledge of CD status, was not useful in discriminating undiagnosed CD cases from non-CD children. The majority of screening-detected CD cases had no CD-associated symptoms or conditions. (Read the full article)

Major depression is common among adolescents. The PHQ-9 has good sensitivity and specificity for detecting depression among adolescents in primary care settings. However, no study has examined the psychometric properties of the PHQ-9 among Chinese adolescents in school settings.

This is the first study to validate the use of the PHQ-9, Patient Health Questionnaire–2 item, and Patient Health Questionnaire–1 item among Chinese adolescents in Taiwan. The PHQ-9 and its 2 subscales have good sensitivity and specificity for detecting depression among school adolescents. (Read the full article)

Tonsillectomy is one of the most commonly performed surgeries in children and is one of the most cumulatively expensive conditions in pediatric hospital care. Little is known about how the quality of tonsillectomy care varies across hospitals.

In a large cohort of low-risk children undergoing same-day tonsillectomy, there was substantial variation in quality measures of process, dexamethasone and antibiotic use, and outcome, revisits to the hospital within the first 30 days after surgery. (Read the full article)

Infants with trisomy 13 (T13) or trisomy 18 (T18) are known to have poor survival. Little is known about how very low birth weight (VLBW) impacts survival and morbidities among infants with T13 or T18.

We examined the risks of mortality and neonatal morbidities for VLBW infants with T13 or T18 compared with VLBW infants with trisomy 21 and VLBW infants without birth defects in a 16-year cohort from the Neonatal Research Network. (Read the full article)

Kawasaki disease (KD) results in coronary aneurysm formation and an increased risk of cardiovascular complications. Modern treatment of acute KD with intravenous immunoglobulin substantially reduces the rate of acute aneurysm formation.

This study reveals that long-term cardiovascular outcomes for KD patients in the current era are not significantly different than matched controls without KD. Late cardiovascular complications are almost exclusively seen in patients with persistent coronary aneurysms. (Read the full article)

The incidence of invasive candidiasis in hospitalized infants is related to postnatal exposures, but large-scale studies relating the incidence of invasive candidiasis to changes in exposures over time are not available.

This study describes the association between the incidence of invasive candidiasis and changes in use of antifungal prophylaxis, empirical antifungal therapy, and broad-spectrum antibacterial antibiotics over time. (Read the full article)

An algorithm for neonatal early-onset sepsis risk based on Centers for Disease Control and Prevention 2002 guidelines for prevention of perinatal Group B Streptococcus disease results in the evaluation of ~12–15% of well-appearing term and late preterm infants.

A revised algorithm based on the Centers for Disease Control and Prevention 2010 guidelines eliminated 25% of all early-onset sepsis evaluations and resulted in significant cost savings, without short-term evidence of harm. (Read the full article)

Serum and salivary cotinine have previously been identified as reliable biomarkers for exposure to tobacco smoke.

We found that detectable serum and salivary cotinine is common among children admitted for asthma and is associated with readmission. This finding may inform clinical care for children at increased risk of asthma morbidity. (Read the full article)

Biomarkers such as C-reactive protein (CRP) and procalcitonin are elevated in children with severe bacterial infections. Children with severe malnutrition are at increased risk of bacterial infections and early markers for the diagnosis of infection in these children are needed.

Despite elevated values in severely malnourished children with invasive bacterial infection or infectious diarrhea, CRP and procalcitonin have limited diagnostic value. CRP could predict death in these children with a good negative predictive value. (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.

Firearm injuries are the second leading cause of death among American children. Previous estimates of nonfatal injuries have relied on small samples of emergency department visits and do not allow a detailed understanding of these injuries among children and adolescents.

In 2009, there were 7391 hospitalizations for firearm-related injuries in US children and adolescents; 89% of hospitalizations occurred in males. Hospitalization rates were highest for 15- to 19-year-olds and for black males. Deaths in the hospital occurred in 6.1% of children and adolescents. (Read the full article)

The Centers for Disease Control and FITNESSGRAM BMI percentile thresholds are commonly used for obesity screening in youth. It is assumed that these thresholds are predictive of metabolic health risk, but little diagnostic data are available.

Both thresholds are predictive of metabolic syndrome, more so for boys than for girls, although with differing sensitivity and specificity. The diagnostic details of the thresholds can inform clinicians and practitioners about how these standards perform in practice. (Read the full article)

In preterm infants receiving supplemental oxygen, manual control of the inspired oxygen fraction is often difficult and time consuming, which may increase the risk of complications. We developed a system for automatic oxygen control and proved its efficacy in the past.

A multicenter study adds evidence for the proposed automatic oxygen control system to significantly improve oxygen administration to preterm infants receiving mechanical ventilation or nasal continuous positive airway pressure while reducing workload compared with routine manual oxygen control.

Sibship size has been negatively associated with children’s language, cognitive, and academic outcomes. This phenomenon is often explained in terms of resource dilution, wherein more children in the home is associated with fewer parental resources allocated to each child.

The current study identifies a moderator of this relationship. Specifically, if children’s next-in-age older siblings exhibit high levels of cognitive sensitivity then sibship size is not significantly related to children’s vocabulary. (Read the full article)

Children who have experienced early psychosocial deprivation are at high risk of persistent, socially indiscriminate behaviors. These behaviors may decline slowly with high-quality caregiving but generally are associated with ongoing impairment.

This study suggests that placement in foster care reduces indiscriminate behaviors to an intermediate level between those in institutional care and community control subjects. It also demonstrates the importance of disorganized early attachment in predicting later indiscriminate behaviors. (Read the full article)

Anabolic-androgenic steroid misuse is not uncommon among adolescent boys, and initial use in adolescence is associated with a host of maladaptive outcomes, including cardiovascular, endocrine, and psychiatric complications.

This is the first known study to examine prevalence rates of anabolic-androgenic steroid misuse as a function of sexual orientation. A dramatic disparity was found, in that sexual minority boys reported misuse at a much higher rate than heterosexual boys. (Read the full article)

Fetal growth restriction, particularly in preterm children, is associated with delayed development and poor growth. Knowledge about the consequences of fetal growth restriction if classified by symmetry is lacking, especially in preterm children.

In preterm children, symmetric and asymmetric growth restriction at birth results in poorer growth later in life. Both groups are at considerable risk of developmental delay because their long-term development is independent of their head circumference at birth. (Read the full article)

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)

Congenital cytomegalovirus (CMV) infection is a leading cause of sensorineural hearing loss and neurodevelopmental impairment in full-term infants. The incidence of congenital CMV infection in preterm infants and the possible associations with developmental outcomes are unknown.

This study defines the incidence of congenital CMV infection in very low birth weight infants and identifies strong associations of congenital CMV infection with hearing loss and adverse neurodevelopmental outcomes in this population. (Read the full article)

Antibiotic use for children has decreased dramatically over the last 20 years. Programs encouraging judicious antibiotic use have focused both on decreasing overall antibiotic use and appropriate prescribing of broad-spectrum agents.

Large declines in antibiotic rates were prominent in the early 2000s. This trend has attenuated, and use has leveled off in some age groups and locales; continued improvement in the use of broad-spectrum agents is possible. (Read the full article)

Asthma morbidity disproportionately affects racial minorities and disadvantaged children. Differences in socioeconomic status and genetics have been offered as explanations but an in-depth understanding of differences in hardships may better explain disparities and also help to identify intervention targets.

Among children admitted for asthma, African Americans were twice as likely to be readmitted as whites. Nearly half the disparity was explained by socioeconomic status and hardships. Community-based interventions targeting hardships may be more feasible given emerging health care payment reform. (Read the full article)

High sodium intake is considered an indirect cause of obesity because it is often accompanied by higher energy intake and sugar-sweetened soft drink consumption. High sodium intake is associated with increased inflammatory response in adult patients.

This study shows that high sodium intake is positively associated with adiposity, leptin, and tumor necrosis factor-α independent of total energy intake and sugar-sweetened soft drink consumption in healthy white and African American adolescents. (Read the full article)

Concerns have been raised that human papillomavirus (HPV) vaccination could lead to riskier behaviors in vaccinated adolescents, but it is unknown whether changes in risk perceptions after vaccination lead to riskier sexual behaviors.

Risk perceptions following HPV vaccination were not associated with subsequent riskier sexual behaviors in sexually experienced and inexperienced young women. These data contribute to the growing evidence that HPV vaccination does not lead to changes in sexual behaviors among adolescents. (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)

More than 60% of all US tuberculosis cases occur among foreign-born persons, but ~90% of cases in young children occur among US-born; many of these children have foreign-born parents, suggesting that this is an important population for prevention.

This is the first study to calculate tuberculosis rates in US-born children by parental nativity. Compared with US-born children with US-born parents, rates were 32 times higher in foreign-born children and 6 times higher in US-born children with foreign-born parents. (Read the full article)

The majority of caffeine intake among children and adolescents is due to soda and tea consumption. Energy drinks, which provide a potent source of caffeine, have increased in availability in the United States in recent years.

This analysis presents trends in caffeine intake between 1999 and 2010, which have previously not been described in the United States, and reveals the impact of increasing energy drink use, also previously not described, on these trends among children and adolescents. (Read the full article)

Violence is a leading cause of death. The emergency department (ED) can prevent violence through proven interventions; however, these interventions are not broadly implemented. There is little evidence to inform decision-makers of the costs associated with preventing violence.

We report the costs of a brief violence prevention intervention in the ED. We highlight the economic impact of implementation, showing that brief interventions in the ED are an inexpensive way the health care system can prevent violence in adolescents. (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)

Waning effectiveness of 5 doses of acellular pertussis vaccines is well documented after 6 years of age, but data are lacking for fewer doses in younger children.

In 2- to 3-month-old infants, 1 dose of the diphtheria–tetanus–acellular pertussis vaccine gave significant protection against hospitalized pertussis. The effectiveness of 3 doses decreased from 84% between 6 and 11 months to 59% after 3 years. (Read the full article)

A growing body of research suggests that the food environment affects children’s weight. Specifically, living in areas with higher-priced fast foods and soda is associated with lower weight and BMI, whereas higher fruit and vegetable prices demonstrate the opposite association.

Using longitudinal data on lower-income young children, this study finds that higher-priced fruits and vegetables are associated with higher child BMI, but not food insecurity, and that this relationship is driven by the prices of fresh fruits and vegetables. (Read the full article)

Current guidelines recommend renal ultrasound as a screening test after febrile urinary tract infection, with voiding cystourethrogram (VCUG) only if the ultrasound is abnormal. Few studies have evaluated the accuracy of ultrasound as a screening test for VCUG-identified abnormalities.

This study shows that ultrasound is a poor screening test for genitourinary abnormalities identified on VCUG, such as vesicoureteral reflux. Neither positive nor negative ultrasounds reliably identify or rule out such abnormalities. Ultrasound and VCUG provide different, but complementary, information. (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)

Previous analyses have documented increased health care costs for children with autism spectrum disorders but have not provided comprehensive estimates of the total economic burden.

There are substantial additional costs associated with caring for children with autism spectrum disorders, amounting to >$17 000 per child annually. Costs accrued outside of the health care system account for the majority of the financial burden. (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)

Research indicates that bullying, a type of peer victimization, is related to worse mental and physical health. Most previous studies have been cross-sectional and have not examined effects of bullying over time.

This analysis examined longitudinal effects of bullying on mental and physical health from middle school to high school. Experiencing chronic bullying, especially in both the past and present, was associated with worse psychological and physical health. (Read the full article)

In children with congenital toxoplasmosis, ocular lesions can be detected and may relapse after birth despite pre- and postnatal treatment. Long-term ocular outcome beyond puberty and associated prognostic factors are unknown due to limited follow-up.

Our study in 477 patients with treated congenital toxoplasmosis who were followed up to 22 years indicated that new ocular lesions can be detected well into adolescence (with a cumulative probability at 18 years of almost 50%), but they rarely cause severe visual impairment.

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)

Encephalitis in children can cause significant neurologic sequelae, such as motor and cognitive impairment. Previous reported data are based mostly on questionnaires and clinical assessments.

Significant cognitive impairment, attention-deficit/hyperactivity disorder, and learning disabilities are common after childhood encephalitis. Even children who were considered fully recovered may be significantly affected. Identifiable pathogens, abnormal neuroimaging, and abnormal neurologic examination on discharge are risk factors of poor outcome. (Read the full article)
