Indoor tanning has gained widespread popularity among adolescents and young adults. Incidence rates of early-onset basal cell carcinoma also appear to be rising. Scant evidence exists on the impacts of early exposure and whether it leads to early occurrence of this malignancy.

In a US population-based study, indoor tanning was associated with an elevated risk of basal cell carcinomas occurring at or before the age of 50 years, with an increasing trend in risk with younger age at exposure among adolescents and young adults. (Read the full article)

Neurocognitive deficits, academic delays, and behavioral and emotional problems are well documented in school-age children in relation to socioeconomic disadvantage and residential instability. Despite adversity, early intervention can facilitate healthy cognitive, emotional, and social development.

Homeless youth demonstrated elevated rates of untreated psychiatric disorders, low academic achievement, and impaired neurocognition. Mental health and neurocognitive symptoms were associated with vocational outcome. Intervention beyond employment services alone is needed to improve functioning. (Read the full article)

Children born late and moderately preterm are at increased risk of developmental problems compared with term-born peers. Screening for developmental problems in the early years may thus aid in the early identification of children at risk for adverse outcomes.

The Parent Report of Children’s Abilities-Revised has good concurrent validity and 90% sensitivity and 76% specificity for identifying moderate/severe cognitive developmental delay in infants born late and moderately preterm. This parent questionnaire may be used as a clinical screening tool. (Read the full article)

Compared with their peers, pediatric residents who report exposure to community settings anticipate greater future community involvement at the end of training. The impact of community pediatrics training on actual future community involvement is not known.

Pediatricians exposed to enhanced community pediatrics training during residency report greater participation in community activities and greater related skills than their peers nationally. (Read the full article)

Early referral of infants with critical congenital heart disease (CCHD) is recommended to reduce mortality. However, few population-based data have been published showing the relationship between CCHD neonatal mortality and timing of cardiac evaluation at a specialty center.

In neonates with CCHD, 35% were not evaluated at a cardiac center by 4 days of age. These cases accounted for a significant number of CCHD deaths. This information enhances the rationale for pulse oximetry screening of neonates for CCHD. (Read the full article)

Available bowel preparation solutions for colonoscopy continue to represent a challenge for children and their families due to poor taste, high volume, and dietary restrictions with subsequent poor compliance and need to place nasogastric tube for administration.

Low-volume polyethylene glycol (PEG) preparations and sodium picosulphate plus magnesium oxide and citric acid (NaPico+MgCit) are noninferior to PEG 4000 with simethicon for bowel preparation before colonoscopy in children. Given its higher tolerability and acceptability profile, NaPico+MgCit should be preferred in children. (Read the full article)

Passive or opt-out consent has been successfully used to recruit subjects in several investigational studies. However, institutional review boards are often inconsistent in their application of federal regulations regarding passive consent.

This study documented the variability among 24 local institutional review boards in their application of federal regulations regarding passive consent and parental acceptance of a passive consent strategy in a multicenter pediatric study. (Read the full article)

The Centers for Disease Control and Prevention recommends that health departments in all 50 states deliver AFIX (Assessment, Feedback, Incentives, and eXchange) consultations to 25% of federally funded vaccine providers each year. AFIX effectively raises vaccination coverage among young children.

AFIX consultations achieved short-term gains in coverage for 11- to 12-year-olds for vaccines in the adolescent platform. No gains occurred for older adolescents or over the long term. Consultations were equally effective when delivered in-person or by webinar. (Read the full article)

Few studies have performed precise cardiovascular assessments and regular follow-up of congenital rubella syndrome (CRS) patients’ clinical courses. A few studies have reported mortalities among children who have CRS; however, the causes of death have not been precisely described.

A total of 38 CRS cases in Vietnam were studied after a rubella outbreak in 2011. The mortality associated with pulmonary hypertension was significantly high if untreated. Conducting careful cardiologic assessments and providing continuous follow-up for each patient is required. (Read the full article)

Socioeconomic status (SES) often influences timeliness of health care delivery, even in publicly funded systems. Children need prompt surgical care for a variety of time-sensitive developmental conditions, and children of lower SES may be especially vulnerable to delays in surgery.

It is unknown whether a publicly funded system’s ability to provide timely pediatric surgical care is related to SES. In 39 327 consecutive surgical cases, we demonstrate that SES need not influence timeliness of surgical care in a publicly funded system. (Read the full article)

Sudden infant death syndrome and other sleep-related causes of infant mortality have several known risk factors. Less is known about the association of those risk factors at different times during infancy.

Risk factors for sleep-related infant deaths may be different for different age groups. The predominant risk factor for younger infants is bed-sharing, whereas rolling to prone, with objects in the sleep area, is the predominant risk factor for older infants. (Read the full article)

Predicting high-risk populations in congenital diaphragmatic hernia (CDH) can help target care strategies. Prediction rules for infants with CDH often lack validation, are aimed at a prenatal population, and are of limited generalizability. We cannot currently discriminate the highest risk neonates during the crucial period shortly after birth.

This clinical prediction rule was developed and validated on an international database. It discriminates patients and high, intermediate, and low risk of mortality; is easy to apply; and is generalizable to most infants with CDH. (Read the full article)

Most therapeutic products used in children have not been studied in that population. There is a need for special incentives and market protection (pediatric exclusivity) to compensate drug sponsors for studying these products in children.

Of 189 products studied under pediatric exclusivity, 173 (92%) received new labeling information. Pediatric efficacy was not established for 78 (42%), including 81% of oncology drugs. Probability of demonstrating efficacy was related to therapeutic area and year exclusivity was granted. (Read the full article)

Prenatal maternal smoking has been associated with attention-deficit/hyperactivity disorder in children, but the causal nature of this association is unclear. Controlling for the association with paternal smoking has been inconsistent.

Women who used nicotine replacement also had children with a higher risk of attention-deficit/hyperactivity disorder. Mother's smoking behavior appears more important than father's, suggesting a possible causal effect of nicotine exposure or factors related to maternal nicotine dependence. (Read the full article)

Previous studies showed that prevalence of abdominal obesity among US children and adolescents increased significantly between 1988–1994 and 2003–2004. However, little is known about recent time trends in abdominal obesity since 2003–2004.

In 2011–2012, 17.95% of children and adolescents aged 2 to 18 years were abdominally obese defined by waist circumference. The prevalence of abdominal obesity leveled off among US children and adolescents from 2003–2004 to 2011–2012. (Read the full article)

Newborn infants who are predominantly breastfed are much more likely to develop prolonged hyperbilirubinemia than those fed formula, but the prevalence of prolonged hyperbilirubinemia in a largely white, North American, breastfed population is unknown.

Practitioners can be reassured that it is normal for 20% to 30% of predominantly breastfed infants to be jaundiced at age 3 to 4 weeks and for 30% to 40% of these infants to have bilirubin levels ≥5 mg/dL. (Read the full article)

Graduating from high school is associated with better health and health behaviors. However, no rigorous studies have tested whether exposure to a high-performing school improves health or health behaviors, thus the causal relationship is unknown.

Exposure to successful schools can reduce very risky health behaviors among low-income adolescents. The primary mechanism is mostly due to better school retention and also due to better academic achievement. (Read the full article)

Research has shown that HIV-affected children face considerable threats to health and mental health. Few studies have investigated the effects of HIV on the health and well-being of HIV-negative children living with HIV-positive caregivers.

By comparing the prevalence of mental health problems and protective and risk factors among HIV-positive, HIV-affected, and HIV-unaffected children in Rwanda, this study demonstrates that the mental health of HIV-affected children requires policy and programmatic responses comparable to HIV-positive children.

After neonatal extracorporeal membrane oxygenation treatment, children are at risk for neurodevelopmental problems including delayed motor function. So far this has only been studied cross-sectionally until age 7 years.

We describe, in a nationwide evaluation, the longitudinal course of motor function development after neonatal extracorporeal membrane oxygenation with persisting problems up to 12 years. At risk are children with congenital diaphragmatic hernia and those with chronic lung disease. (Read the full article)

Supplemented mother’s own milk is the preferred nutrition for very low birth weight infants.

Through targeted encouragement and guidance, most mothers are able to provide milk to their very low birth weight infants, both for early and prolonged feeding, in an open-bay NICU. (Read the full article)

Growth failure has been frequently reported in children who have obstructive sleep apnea syndrome (OSAS) owing to adenotonsillar hypertrophy. Adenotonsillectomy (AT) has been reported to accelerate weight gain in children who have OSAS in nonrandomized uncontrolled studies.

This randomized controlled trial of AT for pediatric OSAS demonstrated significantly greater weight increases 7 months after AT in all weight categories. AT normalizes weight in children who have failure to thrive, but increases risk for obesity in overweight children. (Read the full article)

Numerous studies have demonstrated clinical benefits of medical emergency team (MET) implementation, including reductions in mortality, cardiac arrests, and critical deterioration events. No studies have evaluated the financial costs and benefits of METs.

The costs of operating an MET can plausibly be recouped with a modest reduction in critical deterioration events. Hospitals reimbursed with bundled payments could see real financial savings by reducing critical deterioration events with a MET. (Read the full article)

Preterm birth has been associated with increased risk of venous thromboembolism (VTE) in infancy, but the longer-term risk is unknown.

In a large national cohort, low gestational age at birth was associated with increased risk of VTE in infancy, early childhood, and young adulthood. These findings call for better awareness of the long-term risk of VTE among preterm birth survivors. (Read the full article)

To date, studies of adaptive behavior in fragile X syndrome have focused on particular age points, either longitudinally or cross-sectionally across a broad age spectrum. Studies have shown variable patterns in adaptive behavior among people with fragile X syndrome.

This study fills a critical gap in knowledge about the profile of adaptive behavior across childhood, adolescence, and young adulthood in fragile X syndrome. This study is the first to incorporate longitudinal data from an age-matched typically developing group. (Read the full article)

Term MRI can assist in identifying the nature and extent of brain injury in preterm infants. However, brain injury detected by MRI does not fully account for neurodevelopmental impairments, particularly cognitive and behavioral impairments, common in preterm survivors.

In addition to brain injury, an assessment of brain growth by using one-dimensional measurements on MRI is helpful for predicting neurodevelopment. Two different patterns of impaired brain growth are observed that relate independently to early cognitive development in preterm infants. (Read the full article)

Delayed diagnosis of critical congenital heart defects (CCHDs) is associated with increased morbidity and mortality.

Despite increasing prenatal diagnosis rates, delayed diagnosis of CCHDs continues to occur, with rates highest among isolated cases and those delivered at nontertiary care hospitals. Better understanding of delayed diagnosis could help to improve screening efforts. (Read the full article)

Neonatal narcotic abstinence syndrome (NAS) has become more prevalent in the United States. There is no strong evidence base for NAS treatment and thus no consensus regarding NAS management, including the best treatment drug or best taper strategy.

This study demonstrates that regardless of the initial treatment opioid chosen, use of a standard treatment protocol with stringent weaning guidelines reduces duration of opioid exposure and length of hospital stay for infants with NAS. (Read the full article)

A previous study suggested that spine and pelvis views may be omitted from the follow-up skeletal survey protocol for suspected child abuse, when these views are normal on the initial skeletal survey, without limiting the sensitivity of the study.

This multicenter study provides estimates of the risk of missing occult fractures in the evaluation of suspected child abuse with omission of spine and pelvis views from the follow-up skeletal survey protocol. Results may be used to update practice recommendations. (Read the full article)

Several studies have revealed an association between cesarean section (CS) and childhood type 1 diabetes. Most of these studies lacked important information on indication for CS and induction of labor. It is unknown whether the reported associations are causal.

Using a cohort of 2.6 million children we found an association between elective CS and type 1 diabetes. The sibling analysis suggested the association is not causal. The findings are crucial evidence to advise women on mode of delivery choice. (Read the full article)

For newborn infants, extreme hyperbilirubinemia (≥24.5 mg/dL) is associated with risk for severe bilirubin encephalopathy. The causal factor of extreme hyperbilirubinemia is often not established. The genotype of Gilbert syndrome, the UGT1A1*28 allele, is considered a potential risk factor.

The UGT1A1*28 allele was not associated with risk for developing extreme hyperbilirubinemia. (Read the full article)

Total serum bilirubin levels ≥30 mg/dL have been labeled as "hazardous." Levels this high are rare, occurring in 3 to 10 per 100 000 births. Few studies have examined etiologies and long-term outcomes in these infants.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a major identifiable cause, but is under-assessed. Chronic, bilirubin-induced neurotoxicity is rare and only occurred in the setting of additional risk factors (prematurity, G6PD deficiency, sepsis) and at levels far above recommended exchange transfusion thresholds. (Read the full article)

A substantial gap exists between what is recommended for effective primary care of children and what takes place. Patient-centered health information technologies have been used to gather information and counsel parents, however, have not been integrated directly with electronic health records nor been speech-based to improve decision-making at the point-of-care.

This study shows that a ubiquitous technology, the telephone, can be successfully used to automatically assess and counsel parents before pediatric primary care visits as well as inform their primary care clinicians in a way that is feasible and effective for multiple important issues. (Read the full article)

Concerns as well as hopes regarding electronic games have led researchers to study the influence of games on children, yet studies to date have largely examined potential positive and negative effects in isolation and using samples of convenience.

Results from this nationally representative study of children 10 to 15 years indicated low levels of regular daily play related to better psychosocial adjustment, compared with no play, whereas the opposite was true for those engaging in high daily play. (Read the full article)

Children with cognitive delay have been shown to have more behavior problems than typically developing children; however, few studies have investigated this relationship over time or among very young children.

Our findings provide some of the first national, prospective evidence that having a cognitive delay may place children at risk for developing and maintaining behavior problems before school age. Early identification and intervention may improve outcomes for these children. (Read the full article)

Clinical decisions must be medically necessary to be approved by insurers. There is a federally mandated medical necessity standard for children in Medicaid, but not in private plans. American Academy of Pediatrics policy calls on pediatricians to help define pediatric medical necessity.

This study reviewed pediatric medical necessity definitions in Medicaid state statutes, regulations, and provider manuals. The federal standard was not replicated on all levels, and provider manuals were least likely to have it. Pediatricians should engage in defining pediatric standards. (Read the full article)

There is substantial variation in the medical care provided to pediatric patients across diverse clinical settings. This variation raises concerns about whether every patient is receiving optimal care and whether more standardized approaches around clinical decisions are needed.

We observed wide variation in admission rates for common pediatric conditions across US children’s hospitals. Our findings highlight the need for greater focus on the standardization of decisions regarding hospitalization of patients presenting to the emergency department. (Read the full article)

Lower respiratory tract infections (LRTIs), including pneumonia, are in the top 10 causes of death among children in the United States. In high-income countries, 3% to 14% of LRTI hospitalizations have been reported to require admission to an ICU.

During 2007–2011, approximately 31 289 hospitalizations for severe LRTI occurred in children each year in the United States. Children <1 year of age had the highest rates of severe LRTI and accounted for 30% of severe LRTI hospitalizations. (Read the full article)

Recent concussion research has examined the role of impact location (ie, the area on the head to which impact occurred); however, no studies exist regarding impact location’s association with concussion outcomes (eg, symptomatology, symptom resolution time, return to play).

This study is the first to examine the association of impact location and concussion outcomes in young athletes. Our findings suggest that impact location, as assessed by sideline observers/player report, is likely of little use in predicting clinical outcomes. (Read the full article)

Herpes encephalitis outside the neonatal period is typically severe and recognizable to clinicians. Excessive testing for herpes encephalitis is associated with increased medical costs and hospital length of stay, and risks patient harm.

Herpes testing and empirical acyclovir treatment in older and less unwell patients has been increasing in US pediatric hospitals over the past decade, which may reflect a more fundamental problem in current approaches to clinical decision-making. (Read the full article)

Previous studies examining developmental outcomes associated with late preterm and early term birth have shown mixed results. Many of these studies did not fully take into account the role of the social environment in child development.

Social factors, not late preterm or early term birth, were the strongest predictors of poor developmental outcomes at 2 to 3 and 4 to 5 years. The influence of mild prematurity may lose strength beyond the neonatal period. (Read the full article)

Children born very preterm (VPT) are at high risk of educational delay. School readiness has been identified as a potentially useful clinical framework for early detection of those at greatest risk. However, evidence to support its predictive validity is limited.

VPT preschoolers are at risk of impairment across the 5 American Academy of Pediatrics school readiness domains. The number of domains affected predicted likelihood of later learning problems, supporting the utility of schoolreadiness frameworks for identifying children needing surveillance and/or support.

Cigarette smoking during adolescence causes significant health problems. Health care providers play an important role in promoting tobacco use abstinence among adolescents, but recent data on the prevalence of provider screening and advice to adolescents are lacking.

This study uses nationally representative surveillance data to provide current estimates of self-reported receipt of health professional screening and advice about tobacco use among US adolescents. Cessation behaviors and correlates of past-year quit attempts among smokers were also explored. (Read the full article)

The prevalence of disability in childhood has been on the rise for the past several decades. Children living in poverty are more likely to have chronic health conditions and experience disabilities.

The percentage of children with disabilities rose 16% between 2001 and 2011. Economically disadvantaged children had the highest rates of disability, but economically advantaged children experienced greater increases in disability. Disability due to neurodevelopmental or mental health conditions rose substantially. (Read the full article)

Rates of human papillomavirus (HPV) vaccination lag behind other adolescent vaccines. Research indicates that provider recommendation is the key to improving HPV vaccination rates and that most adolescents who are unvaccinated received other vaccines, indicating missed opportunities for HPV vaccination.

This study explores in-depth the content of provider–patient conversations that either create or prevent opportunities for HPV vaccination. Effective and ineffective conversations are presented with the goal of providing practical tools to improve communication regarding HPV vaccines. (Read the full article)

The short-term immunogenicity and safety of a HPV4 vaccine have been previously evaluated in preadolescents and adolescents. To date, no long-term studies of the safety, effectiveness, and immunogenicity of the HPV4 vaccine have been reported in this age group.

The HPV4 vaccine administered to adolescents demonstrated durability in clinically effective protection and sustained antibody titers over 8 years. These data, along with extensive postapproval safety surveillance data, should help reinforce national recommendations for HPV vaccination of preadolescents and adolescents. (Read the full article)

Urinary tract infection is the most common serious bacterial illness among febrile infants and young children. Automated urine cytometry may supplant traditional urinalysis, but diagnostic performance at unique pediatric cutpoints has not been described for this labor-saving technique.

We describe new, clinically useful cutpoints for automated leukocyte and bacterial counts. The sensitivity and specificity of bacterial counts ≥250 cells/μL exceed those of other methods. However, point-of-care dipstick tests for leukocyte esterase or nitrite have acceptable performance. (Read the full article)

Prone sleeping is a major risk factor for sudden infant death syndrome (SIDS). Cerebral oxygenation and blood pressure are reduced in the prone sleeping position in healthy term infants. Preterm infants are at significantly increased risk of SIDS.

Preterm infants display reduced cerebral oxygenation compared with term infants, most prominently at 2 to 3 months corrected age in the prone position when blood pressure is concurrently reduced. This may contribute to the increased risk for SIDS among infants born preterm. (Read the full article)

Among US youth 6 to 15 years of age there are differences in strength by gender and age. Little is known about differences in strength by weight status in the US pediatric population.

This study provides current US nationally representative reference values for 4 measures of strength in youth 6 to 15 years old. Body weight was associated with strength, but the association varied depending upon the measure. (Read the full article)

Adolescent males from low-income communities are a group at increased risk of obesity and related health concerns. Obesity prevention interventions targeting adolescents have so far had mixed success. Targeted interventions, tailored for specific groups, may be more appealing and efficacious.

A multicomponent school-based intervention using smartphone technology can improve muscular fitness, movement skills, and key weight-related behaviors among low-income adolescent boys. (Read the full article)

Growth impairment in sickle disease has been a consistent finding in published reports. Hydroxyurea (HU) decreases vasoocclusive events and increases hemoglobin levels, which may improve growth. However, HU may adversely affect growth in young children by its effect on DNA synthesis.

Height, weight, and head circumference were normal in HU-treated children in the study as compared with the World Health Organization standards. Height, weight, and BMI z scores were similar in placebo and treatment groups. There were no harmful effects of HU on growth. (Read the full article)
