Microbial exposure during early life may prevent, or reduce, the risk of allergy development.

Allergic diseases are less common in children whose parents use hand dishwashing instead of machine dishwashing, and we hypothesize that this allergy-preventive effect is mediated via an increased microbial exposure. (Read the full article)

Celiac disease (CD) may develop at any age. Young children with CD are at particular risk for malabsorption and failure to thrive. HLA-DR3-DQ2 homozygotes are at the highest genetic risk and develop CD very early in life.

Most children with CD detected in screening by 4 years of age have no symptoms and normal growth. Symptoms are unrelated to HLA genotype. Autoantibody levels correlate higher with severity of mucosal lesions in symptomatic as compared to asymptomatic children. (Read the full article)

Some parents choose to "spread out" the recommended vaccine schedule for their child by decreasing the number of simultaneous vaccines or delaying certain vaccines until an older age. Epidemiologic studies demonstrate increasing numbers of parents are choosing to delay vaccines.

We demonstrate that almost all providers encounter requests to spread out vaccines in a typical month and, despite concerns, increasing numbers are agreeing to do so. Providers report many strategies in response to requests but think few are effective. (Read the full article)

Childhood bacteremia caused by vaccine-preventable organisms has substantially declined over the last decade. Recognition of bacteremia in children is difficult, and delayed administration of antibiotics is associated with poor outcomes. Adults with health care–associated Gram-negative bacteremia experience delays in receiving appropriate antibiotics.

Bacteremia in children presenting to the emergency department is increasingly health care associated and resistant to empirical antibiotics. These infections are associated with increased length of stay. Rates of Gram-negative bacteremia have increased, and children with Gram-negative bacteremia experience delayed antibiotic administration. (Read the full article)

Acute kidney injury (AKI) occurs in up to 50% of children after cardiopulmonary bypass and is associated with adverse outcomes. Renal biomarkers have been shown to predict postoperative AKI, but few studies have examined cardiac biomarkers for risk classification.

Preoperative levels of creatine kinase-MB and heart-type fatty acid binding protein are strongly associated with the development of postoperative AKI after pediatric cardiac surgery and can be used to improve preoperative clinical risk prediction. (Read the full article)

Strategies are needed to engage families of chronically ill children at home in an ongoing process of shared decision-making regarding treatment that is responsive to families’ concerns and goals and children’s evolving symptoms.

This study evaluated a novel patient portal that facilitates shared decision-making in asthma. The portal was feasible and acceptable to families, improved outcomes, and provides a model for improving care through an electronic health record portal. (Read the full article)

Many children with blunt head trauma and isolated skull fractures are admitted to the hospital. Several small studies suggest that children with simple isolated skull fractures are at very low risk of clinical deterioration.

In this large cohort of children with isolated linear skull fractures after minor blunt head trauma, none developed significant intracranial hemorrhages resulting in neurosurgical interventions. These children may be considered for emergency department discharge if neurologically normal. (Read the full article)

Preterm infants are at an increased risk of infections; therefore, vaccination is of particular importance. Because immune response data reported for preterm infants may vary according to gestational age and vaccination timing, vaccine responses in this population warrant additional research.

This study evaluated 13-valent pneumococcal conjugate vaccine in preterm infants. Results suggest that this vaccine was well tolerated and immunogenic; most subjects achieved serotype-specific immunoglobulin G antibody levels and functional antibody responses likely to correlate with protection against invasive disease.

Topical corticosteroids are often used to treat atopic dermatitis (AD) in infants, although compliance is poor due to concerns over side effects. Pimecrolimus was shown to be a safe and effective noncorticosteroid treatment of AD in infants in short-term studies.

The Petite Study shows that long-term management of mild-to-moderate AD in infants with pimecrolimus or topical corticosteroids was safe without any effect on the developing immune system. Pimecrolimus had similar efficacy to topical corticosteroids and a marked steroid-sparing effect. (Read the full article)

Micronutrient deficiencies, including deficiencies of vitamin B-12 and folate, are common worldwide and may be a contributing factor to the estimated 165 million stunted children.

Routine supplementation of vitamin B-12 improved linear and ponderal growth in subgroups of young Indian children. We provide evidence that vitamin B-12 deficiency is a contributor to poor growth in low- and middle-income countries. (Read the full article)

Concern exists about the ability of new general pediatricians to find jobs that match their career goals.

A large majority of new pediatricians secure positions consistent with their career goals and desired responsibilities. (Read the full article)

Smoking has been found to increase the risk of some specific congenital anomalies; however, results remain inconsistent. Nicotine replacement therapy (NRT) is increasingly being used as for smoking cessation in pregnancy although little is known about its association with congenital anomalies.

Being prescribed NRT while pregnant was not associated with major congenital anomalies (MCA), except a small increase in respiratory anomalies (3/1000 births). This must be considered in context of the rarity of MCAs and higher morbidities in the NRT group. (Read the full article)

Trainee success rates with infant lumbar puncture are poor. The model of just-in-time learning via simulation has produced clinical improvement for other medical skills such as cardiac compressions and central line dressing changes.

This is the first study to evaluate the impact of just-in-time-and-place simulation-based learning on success with infant lumbar puncture. The intervention improved clinical behaviors associated with success without making a significant impact on success with the procedure. (Read the full article)

Children’s time with parents is critical for healthy development. Lack of control over parents’ schedules and limited supervisor support for personal and family life can interfere with parents’ family time.

This is the first group randomized controlled field trial demonstrating effects of a workplace intervention, designed to increase schedule control and supervisor support, on working parents’ time with their children, as assessed by using longitudinal daily telephone interviews.

Current childhood vaccination coverage rates among military dependents in the United States are not known. Past studies on childhood vaccination coverage in military dependents have shown mixed results, with the majority showing lower than ideal coverage rates.

This study analyzes a national database with 6 years of data and provider-confirmed vaccination status to describe the current documented vaccination coverage rates among military dependents in the United States. (Read the full article)

Otorrhea is common in children with tympanostomy tubes: annually, 2 of 3 children develop 1 or more episodes. Antibiotic-glucocorticoid eardrops are the most effective treatment in both the short- and long-term.

Treatment with antibiotic-glucocorticoid eardrops costs less than oral antibiotics and initial observation in children with tympanostomy tubes who develop otorrhea. Non–health care costs constitute a substantial proportion of the total costs of this condition. (Read the full article)

A program to support pediatric primary care providers in mental health care using point-of-care, telephone-based advice from specialists has been available since 2005 in Massachusetts. Other US states are implementing similar models. Little is known about how providers use this service.

There is wide variability in adoption and use of this program. Patterns are associated with panel size, enrollment timing, and assignment to the program team at the pilot site. Findings will help new programs establish expectations and design implementation interventions. (Read the full article)

Clinical trials of the quadrivalent human papillomavirus vaccine show it to be highly efficacious in preventing vaccine-type–specific cervical dysplasia and anogenital warts, but few studies have assessed its effects in the real world and none have done so at the program/population level.

This study provides strong evidence of the early benefits of quadrivalent human papillomavirus vaccination on reductions in cervical dysplasia and possible reductions in anogenital warts among girls aged 14 to 17 years, offering additional justification for not delaying vaccination until girls are older.

Neurodevelopmental disabilities are the most common, and potentially the most damaging, sequelae of congenital heart defects. Children with congenital heart defects undergoing surgery in infancy have problems with reasoning, learning, executive function, inattention and impulsive behavior, language skills, and social skills.

Early neurodevelopmental outcomes for survivors of cardiac surgery in infancy have improved modestly over time, but only after adjustment for innate patient risk factors. As more high-risk infants with congenital heart defects survive cardiac surgery, a growing population will require significant societal resources. (Read the full article)

Outbreaks of serogroup B meningococcal disease occur at universities and other organizations. Until October 2014, options for control of serogroup B outbreaks were limited by the absence of a licensed vaccine for serogroup B meningococcal disease in the United States.

We describe a serogroup B outbreak at a university in 2013 and the campaign with investigational serogroup B vaccine held in response. This was the first use of a serogroup B vaccine as an outbreak response in the United States. (Read the full article)

Disparities in asthma morbidity are exacerbated by underutilization of preventive controller medications. Community pharmacies are well positioned for an increased role in population health. The Asthma Medication Ratio, currently used at the patient-level, could be adapted for use at the pharmacy-level.

A newly developed Pharmacy-level Asthma Medication Ratio was associated with population-level childhood asthma morbidity. Collaborative relationships between physicians, community pharmacists, and patients (and families) have the potential to promote testable interventions aimed at reducing asthma morbidity and cross-community disparities.

Although waning immunity with the childhood pertussis vaccination series has been reported, there are limited data on duration of protection of the adolescent pertussis vaccine (Tdap), especially among those who have received only acellular vaccines.

This study reports that protection from Tdap wanes substantially 2 to 4 years after vaccination among adolescents who received all acellular vaccines during childhood. This waning protection is likely contributing to the increase in adolescent pertussis. (Read the full article)

Few studies have established the protective efficacy of 1 to 3 primary doses of diphtheria-tetanus-whole-cell pertussis (DTwP)/diphtheria-tetanus-acellular pertussis (DTaP) vaccines against pertussis, hospitalization, or pertussis complications in infants. However, vaccine effectiveness against infant pertussis death has not been previously reported.

This is the first study to report the protective role of ≥1 DTwP/DTaP doses among vaccine-eligible infants aged ≥6 weeks against death, hospitalization, and complications from pertussis. It describes risk markers for death among vaccine-ineligible infants aged <6 weeks. (Read the full article)

Meaningful use (MU) incentive payments have been developed to encourage adoption and use of electronic health records (EHRs). Several studies have revealed children’s hospitals have unique barriers to the use of EHRs but were relatively early adopters of information technology.

Although a minority of children’s hospitals have succeeded with MU incentives, freestanding children’s hospitals are significantly more likely to succeed. Improvement of EHRs for pediatric use should focus on information exchange, quality reporting, and MU relevance to pediatrics. (Read the full article)

Concussion produces a range of symptoms that may impede academic functioning. The need for empirical validation exists, despite growing consensus on the importance of a guided return-to-school process for students recovering from concussion.

This study provides initial evidence of a concussion’s adverse effects on academic learning and performance across all grades, including heightened levels of school-related concern and amplified postinjury academic difficulties experienced by symptomatic students relative to their recovered peers.

The majority of youth are not meeting the recommended physical activity guidelines. Dance classes are popular for girls and have potential to provide physical activity for many youth. Little is known about how active youth are in different dance types.

Objectively measured physical activity in dance classes are low and generally provide less physical activity than youth sports. There is a public health imperative to engage the dance profession in efforts to improve the health impact of youth dance classes. (Read the full article)

Physical activity (PA) of preschoolers has been found to be highly correlated with their child care environment. Preschool-aged children are sedentary for most of their time at child care and most are not meeting PA recommendations.

Preschoolers were presented with significantly fewer than recommended PA opportunities at child care. More active play opportunities are needed to increase PA, including more outdoor time, more teacher-led and child-initiated active play, and flexibility in naptime for preschoolers.

Suboptimal brain development and increased risk of cognitive deficits are well documented in very low birth weight children. Supplementation with docosahexaenoic acid and arachidonic acid has been associated with positive cognitive effects.

This follow-up study of a randomized controlled trial of supplementation with docosahexaenoic acid and arachidonic acid to very low birth weight infants is the first report on both cognition and brain macrostructure measured with MRI. No cognitive or neuroanatomical effects were detected at 8 years. (Read the full article)

Distribution of infant formula discharge packs to breastfeeding mothers is common practice in maternity care facilities in the United States. Receiving discharge packs is associated with shortened exclusive breastfeeding duration. Many efforts have been made to discourage this practice.

From 2007 to 2013, there has been a marked reduction in distribution of discharge packs containing infant formula to breastfeeding mothers in hospitals and birth centers in the United States. (Read the full article)

The sensitivity of the urinalysis (UA) traditionally has been considered suboptimal in young infants. Whether the finding of a negative UA and a positive urine culture represents a false-negative UA versus a false-positive urine culture remains unclear.

In infants <3 months with bacteremic urinary tract infection, a condition that represents true infection, the UA sensitivity is higher than previously reported for urinary tract infection in general, suggesting that the UA is reliable even in young infants. (Read the full article)

Most prospective cohort studies of acquired demyelinating syndromes in children have focused on the genetic, environmental, and neuroimaging predictors of multiple sclerosis. Less is known regarding the severity of the incident demyelinating event and predictors of residual attack–related physical disability.

In a national, prospective longitudinal study, incident acquired demyelinating syndromes in children were characterized in terms of physical deficits and acuity at onset, and recovery over the first 12 months. Follow-up evaluations up to 10 years’ postonset were analyzed. (Read the full article)

An increasing number of children are unvaccinated at entry into public schools, potentially endangering children who cannot be vaccinated for medical reasons and threatening herd immunity. Voluntary exemptions from immunizations vary geographically and by parental characteristics.

We find that exemption behavior is highest in peripheral areas of cities and that specific types of student populations are associated with high exemption rates. Additionally, there is spatial overlap between clusters of high personal exemption and medical exemption populations. (Read the full article)

Parental hesitancy about childhood vaccines is prevalent and related to delay or refusal of immunizations. Physicians are highly influential in parental vaccine decision-making, but may lack confidence in addressing parents’ vaccine concerns.

A physician-targeted communications intervention designed to reduce maternal vaccine hesitancy through the parent-physician relationship did not affect maternal hesitancy or physician confidence communicating with parents. Further research should determine the most effective approaches to addressing vaccine hesitancy. (Read the full article)

Vesicoureteral reflux is recognized as an important risk factor for recurrent urinary tract infection and renal scarring. Less is known about the contribution of other risk factors to these outcomes.

This study found that information about vesicoureteral reflux and bladder and bowel dysfunction can be used to identify children at low, medium, and high risk of recurrent urinary tract infection, information that clinicians could use to select children for specific preventive therapies.

"Protective" complementary feeding practices that promote self-regulation of intake and development of healthy food preferences have been positively associated with healthy child eating patterns and growth. There are few high-quality trials evaluating feeding practice interventions; none has reported long-term outcomes.

This large randomized controlled trial demonstrates that anticipatory guidance on the "how" of complementary feeding resulted in more protective feeding practices. These intervention effects were sustained for 3 years and translated into commensurate trends in obesity risk. (Read the full article)

Conventional invasive pneumococcal disease (IPD) definition using laboratory confirmation lacks sensitivity. Using a vaccine-probe design, the FinIP trial showed that IPD disease burden and vaccine-preventable disease incidence were fourfold higher when a more sensitive outcome, clinically suspected IPD, was used.

Vaccine-preventable disease incidence (ie, absolute reduction due to PCV10 vaccination) during routine vaccination program was threefold with the more sensitive outcome of clinically suspected IPD compared with the conventional IPD definition. This has major implications for cost-effectiveness of PCVs. (Read the full article)

Associations have been reported between celiac disease (CD) and numerous autoimmune conditions in adults and children. However, current screening guidelines do not consider patients with rheumatic diseases to be at high risk for CD.

The prevalence of CD in children presenting for rheumatology evaluation was found to be 2% by routine serologic screening. The majority of screening-detected CD cases had no CD-associated symptoms. Gluten restriction was found to relieve some musculoskeletal complaints. (Read the full article)

Prophylactic vaccination of young women 16 to 26 years of age with the 9-valent human papillomavirus (HPV)–like particle (9vHPV) vaccine prevents infection and disease with vaccine HPV types.

These data support bridging the efficacy findings with 9vHPV vaccine in young women 16 to 26 years of age to girls and boys 9 to 15 years of age and implementation of gender-neutral HPV vaccination programs in preadolescents and adolescents. (Read the full article)

Screening for occult fractures is a key component of the medical evaluation for young victims of suspected physical abuse. Little is known about adherence to occult fracture evaluation guidelines in children with suspected abuse cared for at non-pediatric-focused hospitals.

Occult fracture evaluations were performed in half of young children diagnosed with abuse or injuries concerning for abuse in a large cohort of hospitals. Evaluations were more common at hospitals caring for higher volumes of young, injured children. (Read the full article)

Weak recommendations exist to guide emergent neuroimaging decisions in children with first, unprovoked seizures. The prevalence of and risk factors associated with clinically relevant abnormalities on neuroimaging have not been well defined in prospective studies.

Clinically relevant intracranial abnormalities on neuroimaging occur in 11% of children with first, unprovoked seizures. Emergent/urgent abnormalities, however, occur in <1%, suggesting that most of these children do not require emergent neuroimaging. Specific clinical findings identify patients at higher risk.

Electronic cigarette (e-cigarette) use in adolescence is increasing. E-cigarette use has been associated with cigarette use, but there has been little study of other psychosocial risk factors for e-cigarette use and their relationship with cigarette use.

Approval and use of e-cigarettes and cigarettes among friends and family were strongly associated with cigarette and e-cigarette use in a cohort of adolescents in southern California. (Read the full article)

Interactive activities and routines promote early childhood language skills and subsequent educational achievement. Population studies describing parent-child participation in interactive activities and their associations with early child development among vulnerable populations are needed.

Significant disparities exist in parenting practices that promote child development between economically advantaged and disadvantaged parents. Participating in less interactive activities was associated with increased risk of developmental delay among low-income families, suggesting a need to enrich parenting practices.

The routine childhood immunization schedule is crowded during the first 2 years, leading to deferred doses and limiting the addition of new vaccines. Combination vaccines can reduce the "shot burden" and improve coverage rates and timeliness.

Antibody response rates to antigens contained in an investigational hexavalent vaccine (DTaP5-IPV-Hib-HepB) were noninferior to licensed comparator vaccines when given as a 3-dose infant series. The safety profile was similar to control except for increased rates of mild-to-moderate, self-limited fever. (Read the full article)

Previous studies have shown that concomitant administration of the quadrivalent human papillomavirus vaccine with MCV4 and Tdap was generally well tolerated and did not interfere with the immune responses to the respective vaccines.

Concomitant administration of the novel 9-valent human papillomavirus vaccine with MCV4 and Tdap, 2 vaccines that are currently recommended for routine vaccination of adolescents, did not compromise the safety, tolerability, and immunogenicity of the individual vaccines. (Read the full article)

The American Academy of Pediatrics recommends parent-child reading from infancy through at least kindergarten, the span of maximal brain growth. Home literacy environment, including reading behaviors and access to books, has been shown to promote oral language and print concepts.

Home reading environment is positively associated with activation of brain areas supporting narrative comprehension and mental imagery in preschool children. This offers novel insight into the neurobiological foundations of emergent literacy and potential effect of shared reading during early childhood. (Read the full article)

In adults, there is significant increased length of stay, cost, and/or resource use associated with hospital-acquired conditions. Less is known about the epidemiology and impact of many hospital-acquired conditions in pediatric populations.

We find increased pediatric length of stay and costs due to venous thromboembolism and catheter-associated urinary tract infections. This is essential information for hospital administrators and safety departments who are planning interventions to reduce harm associated with these hospital-acquired conditions.

Rudeness is routinely experienced by hospital-based medical teams. Individuals exposed to mildly rude behavior perform poorly on cognitive tasks, exhibit reduced creativity and flexibility, and are less helpful and prosocial.

Rudeness had adverse consequences on diagnostic and procedural performance of members of the NICU medical teams. Information-sharing mediated the adverse effect of rudeness on diagnostic performance, and help-seeking mediated the effect of rudeness on procedural performance. (Read the full article)

Research has shown that parent feeding practices are associated with adolescent weight status and dietary intake. It is unknown whether certain factors such as parent and child weight status concordance or discordance influence parents’ use of specific feeding practices.

Findings from the current study suggest that parents use the highest levels of pressure-to-eat feeding practices when parents and adolescents are both nonoverweight and the highest levels of food restriction when parents and adolescents are both overweight/obese. (Read the full article)

Infants born very prematurely or with a very low birth weight are known to have an increased risk of attention-deficit/hyperactivity disorder (ADHD). Results concerning late preterm children are controversial and studies examining fetal growth represented by weight for gestational age are scarce.

We demonstrate that each declining week of gestation increases the risk of ADHD. Also, late preterm infants have an increased risk. Furthermore, as weight for gestational age becomes smaller than 1 SD below the mean, the risk of ADHD increases. (Read the full article)

Many studies have suggested that autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are commonly co-occuring neurodevelopmental conditions.

In children with co-occurring ASD and ADHD, an initial ADHD diagnosis may be associated with delayed ASD diagnosis and a higher likelihood of ASD diagnosis older than 6 years of age. Clinicians should consider ASD when evaluating young children presenting with ADHD symptoms. (Read the full article)
