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)

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)

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)

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)

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

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

Because of high costs of newer vaccines, financial risk to private vaccination providers has increased. Previous studies have shown general dissatisfaction with payment for the cost of vaccines and administration fees, with some providers considering no longer providing childhood vaccines.

We show that many providers are dissatisfied with payment for vaccine purchase and administration from all types of payers and that, for new vaccines, providers are using a variety of strategies with parents to handle uncertainty about insurance coverage. (Read the full article)

Many parenting Web sites encourage use of infant "sleep machines" to play ambient noise while infants sleep. Noise recommendations for hospital nurseries suggest a limit of 50 A-weighted dB, whereas occupational standards limit exposure times for noise >85 A-weighted dB.

We measured the maximum sound level outputs of infant sleep machines and found that several devices are capable of producing levels that may be damaging to infant hearing and may be detrimental to auditory development. (Read the full article)

Maintaining high levels of measles-mumps-rubella immunization is an important public health priority that has been threatened by discredited claims about the safety of the vaccine. Relatively little is known about what messages are effective in overcoming parental reluctance to vaccinate.

Pro-vaccine messages do not always work as intended. The effectiveness of those messages may vary depending on existing parental attitudes toward vaccines. For some parents, they may actually increase misperceptions or reduce vaccination intention. (Read the full article)

The first evaluation of the economic impact of all vaccines in the routine US childhood immunization schedule assessed the 2001 schedule (excluding pneumococcal conjugate and influenza vaccines) and documented substantial cost savings over the lifetimes of the cohort of children born in 2001.

This report updates our previous evaluation, and estimates the costs and benefits of vaccinating the cohort of children born in 2009. We include vaccines routinely recommended for children in 2009. (Read the full article)

Individuals living in Mediterranean countries have historically had a lower risk of cardiovascular disease. Important changes in diet and lifestyle have taken place in these countries in recent years, and it is unknown how these changes might influence current cardiovascular health.

Fitness and fatness levels indicate that urban adolescents from southern Europe are less healthy than those from central northern Europe. The extent to which these differences might be explained by physical activity, diet, and genetics is analyzed and discussed in this article. (Read the full article)

Individuals with DiGeorge syndrome (DGS) have varying degrees of immunodeficiency. All are susceptible to vaccine-preventable infections with serious complications. Although live vaccines are generally contraindicated in this population, limited evidence suggests that they may be effective and safe for select individuals.

Many individuals with DGS received live vaccines despite having a known diagnosis. Adverse events following live immunizations were typically minor and self-limited, suggesting that live vaccines may be considered for patients with DGS who exhibit mild-to-moderate immunosuppression.

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

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

In the United States, given the high burden of disease, influenza vaccine is recommended for all children from age 6 months. The paucity of vaccine effectiveness data in children <2 years has led some to argue against routine vaccination in this age group.

This study reveals the effectiveness of trivalent influenza vaccine in young children and supports the current Advisory Committee on Immunization Practices recommendation. This study provides the strongest evidence to date confirming the effectiveness of trivalent influenza vaccine in children <2 years of age. (Read the full article)

Owing to genetic variability in its metabolism, codeine can lead to fatal toxicity or inadequate treatment in pediatric subpopulations and several guidelines have recommended against its use in children. Little is known about codeine prescribing for children in the United States.

There has been a small decline in pediatric codeine prescriptions overall in emergency departments, but no change in prescription for children who have cough or upper respiratory infection, despite professional recommendations against this practice. Substantial numbers of children are being prescribed codeine annually. (Read the full article)

Practice standards for managing adult cervical spine injuries (CSIs) are well established. However, pediatric CSIs are rare and different from those of adults, preventing extrapolation from adult practice and illustrating the need for larger multicenter investigations of CSIs in children.

This study comprehensively describes CSIs in a large multicenter pediatric cohort. The large number of young children included allowed us to comprehensively explore the relationship between CSI pattern and age, mechanism of injury, comorbid injuries, surgical interventions, and neurologic outcome.

Chorioamnionitis (CAM) is a major risk factor for early-onset neonatal sepsis. The Committee on the Fetus and Newborn recommends extending the duration of antimicrobial therapy in neonates exposed to CAM and intrapartum antibiotics if laboratory data are abnormal, even if culture results are sterile.

When managed by using a strategy similar to recent Committee on the Fetus and Newborn guidelines, a large number of term and late-preterm infants exposed to CAM who had sterile blood culture findings were treated with prolonged antibiotic therapy, subjected to additional invasive procedures, and had prolonged hospitalization.

Central line–associated bloodstream infections (CLABSI) are common types of hospital-acquired infections associated with high morbidity and cost. In recent years, quality improvement initiatives have demonstrated how to reduce the incidence of CLABSI.

This study presents nationally representative estimates of the cost and length of stay attributable to pediatric CLABSI. We make the business case to justify quality improvement prevention initiatives and the adoption of strategies for cost-effective management of CLABSI. (Read the full article)

Cotinine assays for dried blood spots have been developed but not deployed in a large sample of newborn specimens.

Cotinine levels consistent with active maternal smoking were detectable in 12% of newborn blood spots, although 41% of the mothers reportedly did not smoke. Data confirm that reported smoking during pregnancy is an imperfect measure of prenatal tobacco smoke exposure. (Read the full article)

Rotavirus vaccination is discouraged during hospitalization, given concerns regarding live-attenuated virus transmission; vaccination is recommended upon NICU discharge for eligible infants, however. Vaccination must be initiated before 104 days of age or infants become age-ineligible.

RotaTeq vaccine administered with routine 2-month vaccinations within the NICU was tolerated in recipients, with no suggestion of symptomatic nosocomial transmission to neighboring unvaccinated infants. (Read the full article)

Since the introduction of rotavirus vaccines, diarrhea-associated health care utilization among US children has decreased substantially. Moreover, indirect benefits from rotavirus vaccination have been observed in unvaccinated children and in adults.

With increasing rotavirus vaccine coverage during 2009–2011, we observed continued reductions in diarrhea-associated health care utilization and cost. Both rotavirus vaccines conferred high protection against rotavirus hospitalizations; pentavalent rotavirus vaccine provided durable protection through the fourth year of life.

Rates of performing skeletal survey (SS) for young children presenting with fractures and at risk for abuse vary substantially across providers, with disparities associated with patients’ characteristics. Lack of consensus regarding indications for SS also contributes to this variation.

The results of this study provide a set of explicit consensus guidelines, based on the literature and on the knowledge of experts from several medical specialties, for identifying children with fractures who should undergo an initial SS. (Read the full article)

Caffeine has predictable effects on cardiovascular function in both adults and children. Our previous work has shown that there are gender differences in this cardiovascular response, with boys having a greater change in heart rate and blood pressure than girls.

This study shows that the gender differences in cardiovascular response to caffeine emerge after puberty and there are some differences in postpubertal girls across the menstrual cycle. (Read the full article)

Invasive pneumococcal disease causes enormous morbidity in children. The spectrum and severity of illness caused by pneumococcal serotypes not present in the current vaccine, and whether the clinical profile and severity of disease have changed, are largely unknown.

Initial data suggest that nonvaccine serotypes are more common in children with underlying conditions, who have greater morbidity from disease. In the post-PCV13 era, a larger proportion of patients are hospitalized, but mortality rates are unchanged. (Read the full article)

Oral vaccine responses are low in children from less-developed countries perhaps as a result of intestinal dysbiosis. New high-throughput DNA-based methods allow characterization of intestinal microbiota as a predictor of vaccine responses.

High abundance of stool Actinobacteria, including Bifidobacterium, was associated with higher responses to oral and parenteral vaccines and a larger thymus in Bangladeshi infants. Conversely, high abundance of Clostridiales, Enterobacteriales, and Pseudomonadales was associated with neutrophilia and lower vaccine responses. (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)

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)

Practitioners caring for critically ill infants need to acquire competence in insertion of chest tubes for pneumothorax. Ethical and logistic concerns inhibit the use of animals, and there are no realistic simulation models available for neonatal chest tube insertion training.

An inexpensive, nonanimal chest tube insertion model can be easily constructed and used effectively to train interns and residents to improve their knowledge, clinical skills, and comfort levels to perform the chest tube insertion procedure in infants. (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)

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.

Messages emphasizing societal benefits of vaccines have been linked to increased vaccination intentions in adults. It is unclear if this pattern holds for parents deciding whether to vaccinate their children.

Findings suggest that health care providers should emphasize the direct benefits of MMR vaccination to the child. Mentioning societal benefits seems to neither add value to, nor interfere with, information highlighting benefits directly to the child. (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)

Cardiovascular risk begins in childhood. New clinical guidelines established a care strategy for lowering risks. Incorporation of guidelines into routine practice lags due to barriers related to knowledge and attitudes about guidelines, as well as behaviors of practitioners, patients, and clinical systems.

This study demonstrated that a multifaceted approach including tools, education, and support for changes in practice systems can accelerate the adoption of guidelines during routine pediatric well-child visits, compared with dissemination of the guidelines alone. (Read the full article)

Public awareness and usage of physician-rating Web sites have been increasing over the last few years. Such ratings can influence adults’ decisions about choosing a physician, but their influence on decisions for children’s physicians has not been characterized.

In this nationally representative survey of parents, we found that the majority (74%) are aware of rating Web sites and slightly more than one-quarter (28%) had sought information on rating Web sites when choosing a primary care physician for their children. (Read the full article)

In 2003, the US Food and Drug Administration issued warnings about hyperglycemia and diabetes with second-generation antipsychotics (SGAs). Since 2004, hyperglycemic and diabetes risk with SGAs has been stated in product labels, and published guidelines have recommended baseline metabolic screening.

Between 2006 and 2011, 11% of children 2 to 18 years starting an SGA had baseline glucose assessed. Youth at risk for diabetes may not be identified. Further, lack of screening impedes determining the contribution of SGAs to hyperglycemia. (Read the full article)

Direct antiglobulin titer (DAT) positive, blood group A or B newborns born to group O mothers have a high incidence of hyperbilirubinemia, attributable to increased hemolysis.

DAT ++ readings were associated with a higher incidence of hyperbilirubinemia and a greater degree of hemolysis than DAT ± or DAT + counterparts. DAT strength should be taken into consideration when planning treatment strategies or follow-up of ABO-heterospecific newborns. (Read the full article)

National adolescent vaccination coverage estimates in 2013 among 13- to 17-year-olds are 86% for Tdap vaccine and 78% for MCV4. Comparatively, coverage with ≥3 doses of HPV vaccine is 38% among girls and 14% among boys.

One-fourth of 11-year-olds had HPV vaccine co-administered with Tdap vaccine, compared with two-thirds who had MCV4 co-administered. Whereas by age 17 years, >92% received Tdap vaccine and MCV4, only half of girls and one-fifth of boys completed HPV vaccination. (Read the full article)

Pneumococcal conjugated vaccines (PCVs) are known to decrease invasive pneumococcal disease in children, but their effect on pneumonia necessitating hospitalization is more variable across study sites, and effects on hospitalization for sinusitis have not been shown previously.

There was a significant decrease in hospitalizations for sinusitis in children <2 years of age, and hospitalization for pneumonia decreased in children aged <5 years after sequential introduction of PCV7 and PCV13. (Read the full article)

Research suggests that appearance-focused messages and exaggerated depictions of sexual activity in the media negatively influence adolescents’ body and sexual self-perceptions. As adolescents increasingly use the Internet to explore their sexuality, health risks related to online behaviors should be identified.

This 4-wave study examined the prevalence and development of 2 receptive and 2 interactive sex-related online behaviors and their relations with adolescents’ body and sexual self-perceptions. It further investigated which parental strategies regarding Internet use may reduce risky sex-related online behaviors. (Read the full article)

Primary ciliary dyskinesia presents in infancy with unexplained neonatal respiratory distress, yet diagnosis is often delayed until late childhood. Earlier diagnosis facilitates earlier onset of therapy, which may help to reduce long-term pulmonary morbidity and mortality.

A diagnostic workup for primary ciliary dyskinesia should be considered in a term infant presenting with unexplained respiratory distress and either lobar collapse, situs inversus, or a prolonged oxygen therapy requirement (>2 days). (Read the full article)

Influenza vaccine coverage is low, and young children in need of 2 doses in a given season are at particular risk, with less than half receiving both doses. Text message vaccine reminders increase receipt of first dose of influenza vaccine.

Little is known about what types of text message reminders are most effective, including embedding educational information. We demonstrate that text message reminders increase timely receipt of the second dose of influenza vaccine and embedding health literacy information improves effectiveness. (Read the full article)

Frequency of influenza vaccination is low, partially because of missed opportunities to vaccinate. Barriers to implementing successful influenza vaccination reminders in the electronic health record include alert fatigue and incomplete vaccination information due to scattered records.

A noninterruptive, immunization information system–linked influenza vaccination reminder can increase vaccination late in the winter when fewer vaccine doses are usually administered. Tailoring the reminder to clinicians’ needs can increase its use. (Read the full article)

Measles-containing vaccines are associated with several types of adverse events. Because measles-mumps-rubella-varicella (MMRV) versus separate measles-mumps-rubella (MMR) and varicella (MMR + V) vaccine increases a toddler’s risk for febrile seizures, we investigated whether MMRV is riskier than MMR + V and whether either vaccine elevates risk for additional safety outcomes.

Comparing MMRV with MMR + V, no increased risk of immune thrombocytopenia purpura, anaphylaxis, ataxia, arthritis, meningitis/encephalitis, acute disseminated encephalomyelitis, and Kawasaki disease was detected. No new safety concerns were identified after either vaccine, and most outcomes studied were unlikely after either vaccine. (Read the full article)

Pediatric traumatic brain injury (TBI) contributes to impairments in functioning across multiple settings. Online family problem-solving therapy may be effective in reducing adolescent behavioral morbidity after TBI. However, less is known regarding maintenance of effects over time.

This large randomized clinical trial in adolescents with TBI is the only study to examine maintenance of treatment effects. Findings reveal that brief, online treatment may result in long-term improvements in child functioning, particularly among families of lower socioeconomic status. (Read the full article)

Poverty is prevalent among children in the United States, and it has a clear association with negative health outcomes. Smoking and passive smoke exposure are both more common among socioeconomically disadvantaged populations and are associated with asthma morbidity.

Reported family hardships were common among children admitted for asthma or wheezing, and most were associated with detectable tobacco smoke exposure. The cumulative number of hardships was also associated with greater odds of tobacco smoke exposure. (Read the full article)

Uptake of rotavirus vaccines has increased steadily since introduction. Despite their demonstrated impact, rotavirus vaccine coverage is lower than for other vaccines recommended in infancy and disease continues to occur.

We observed higher rotavirus detection rates among patients from provider locations with lower rotavirus vaccine coverage; providers who do not offer rotavirus vaccine to age-eligible children may create pockets of susceptible children that serve as reservoirs of ongoing disease transmission. (Read the full article)

Parent refusal and delay of childhood vaccines has increased in recent years and is believed to cluster in communities. Such clustering could pose public health risks and barriers to achieving quality benchmarks for immunization coverage.

We found that underimmunization and vaccine refusal cluster geographically. Spatial scan analysis may be a useful tool to identify locations where clinicians may face challenges to achieving benchmarks for immunization coverage and that deserve special focus for interventions.

Bruising is common in young victims of physical abuse as well as in cases of accidental trauma. There is uncertainty regarding which young children with bruising require evaluation with skeletal survey for possible abuse.

The results of this study provide guidelines, based on the literature and knowledge of experts, for identifying children <24 months presenting for care in the hospital setting with bruises, who should and should not undergo skeletal survey. (Read the full article)

Increased central adrenergic activity occurs with opiate withdrawal. Clonidine is an effective drug as an adjunct to morphine in the treatment of neonatal abstinence syndrome. It is unclear whether clonidine is effective as single-drug therapy.

Clonidine, a α₂-adrenergic agonist, seems to be as effective as morphine when used as a single-drug therapy for neonatal abstinence syndrome. Its administration results in improvement in neurobehavioral performance. (Read the full article)
