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)

More than a quarter of child deaths in the United Kingdom are estimated to have identifiable failures in care. Although children account for 40% of the family practice workload, little is known about iatrogenic harm to children in this setting.

This is the first analysis of nationally collected pediatric safety incident reports from family practice. To mitigate harm to children, priority areas requiring improvement include medication provision, referral of unwell children, provision of evidence-based treatment, and adequate diagnosis and assessment.

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)

Infants with an inconclusive diagnosis of cystic fibrosis after newborn screening may turn out to have cystic fibrosis. However, little is known about the incidence, characteristics (phenotype and genotype), and outcomes of these infants to guide investigations and follow-up.

In this prospective longitudinal study, a proportion (11%) of infants with an initial inconclusive diagnosis were subsequently diagnosed with cystic fibrosis. This finding underscores the need for follow-up of this population. (Read the full article)

Infants born extremely premature and infants born to adolescent mothers are at risk for adverse developmental and behavior outcomes. There is limited research on the dual risk imparted to infants born extremely premature to adolescent mothers.

Extremely premature infants of adolescent mothers have significantly increased rates of behavior problems. Nonwhite race and living in ≥3 places by 18 to 22 months of age are risk factors for adverse behavior outcomes among infants of adolescent mothers. (Read the full article)

Little is known about the prevalence or outcomes of infants with indeterminate diagnostic results after a positive cystic fibrosis (CF) newborn screen (CF transmembrane conductance regulator–related metabolic syndrome [CRMS]).

CRMS accounted for 15.7% of newborn screened diagnoses in the CF Patient Registry from 2010 to 2012 (CRMS:CF ratio = 5.0:1.0). Although most infants were healthy, some infants demonstrated clinical features concerning for CF. (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)

Newborn screening for critical congenital heart defects (CCHDs) has been implemented in many hospitals, yet there is uncertainty about the number of infants with CCHDs that might be detected through universal implementation of newborn CCHD screening in the United States.

We estimated that ~875 infants with CCHDs might be detected, and ~880 missed, annually through universal CCHD screening in the United States. Increases in prenatal diagnosis are unlikely to substantially impact the number of infants detected through CCHD screening. (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.

Early detection of scoliosis facilitates treatment. For detection, topographic features, such as truncal asymmetry or rib hump, are used.

We show a correlation between curve magnitude at presentation and BMI. Obesity may obscure physical examination findings. (Read the full article)

Care coordination is a central part of the medical home model. Little is known about how care coordination is implemented in pediatrics and how it changes over time in primary care practices successfully adopting medical home principles.

In high-performing medical homes, care coordination evolved toward designing and carrying out routine activities and policies that aimed to forestall disruptions in care delivery. Investing in medical home teams, engaging electronic medical record systems, and improving workflow supported these changes. (Read the full article)

Harm occurs at a high rate in adult inpatient populations. One single-center study, applying an adult-based surveillance tool, suggests that a pediatric inpatient population also has a high rate of harm.

Harm occurred frequently in 6 freestanding children’s hospitals. Identification and understanding of the harm is the first step to making necessary improvements and to preventing future harm. (Read the full article)

Evidence on the cardiometabolic consequences of sedentary behavior in youth is inconsistent and mostly relies on cross-sectional studies. Studies with objective measures of sedentary time have found limited evidence of cross-sectional associations with adiposity markers but no other outcomes.

Objectively assessed daily sedentary time was not prospectively associated with cardiometabolic outcomes. Moderate to vigorous physical activity was beneficially associated with body fat mass, insulin, high-density lipoprotein cholesterol, and clustered cardiometabolic score. (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)

Various clinical and demographic factors are associated with sudden infant death syndrome (SIDS), and an association between altitude of residence and SIDS has been questioned but not yet demonstrated in any large observational studies.

This study demonstrates an association between altitude and SIDS, with higher SIDS rates observed at high elevation (>8000 feet) than at the more moderate elevations (<6000 feet). (Read the full article)

Dyslexia has a lifelong impact on learning. The consensus in the literature from clinical studies is that dyslexia is not caused by vision abnormalities. However, interventions and therapies directed at eye-related functions are still available.

In this cohort the majority of dyslexic children had normal results for all ophthalmic tests. These population-based data support the consensus that dyslexia is not primarily a vision problem and that vision-based therapies are not justified or likely to help. (Read the full article)

Fifteen percent of tuberculosis cases globally are resistant to the drug isoniazid. Isoniazid resistance puts patients with tuberculosis at risk for poor treatment outcomes and threatens the effectiveness of isoniazid preventive therapy in people with latent tuberculosis infection.

We present the first global and regional estimates of the proportion of children with tuberculosis who have isoniazid-resistant disease, showing large geographic variations in risk of resistance. We estimate the number of annual incident cases of isoniazid-resistant tuberculosis in children. (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)

Clinical pain assessment methods in youth are vulnerable to underestimation bias and underrecognition. Facial expressions are sensitive, specific biomarkers of the presence and severity of pain. Computer vision–based pattern recognition enables measurement of pain-related facial expressions from video.

This study demonstrates initial validity for developing computer vision algorithms for automated pain assessment in children. The system developed and tested in this study could provide standardized, continuous, and valid patient monitoring that is potentially scalable. (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)

Studies on the consequences of abnormal prenatal hemoglobin (Hb) concentration have focused on maternal morbidities and adverse birth outcomes. To date, very little is known about the association between prenatal Hb concentration and infant cognitive and motor functions.

There is an inverted U-shaped relationship between maternal Hb concentration and infant gross motor function. Hb concentration between 90 and 110 g/L appears to be optimal for early gross motor function of children. (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)

Firearms are among the 10 leading causes of injury-related death for youth and continues throughout the life span. Annually youth homicides and assault-related injuries result in an estimated $16 million in combined medical and work loss costs.

Findings add to the field’s broadening conceptualization of youth victimization highlighting the potentially highly consequential risk factor of firearm and other weapon exposure as a component of victimization experiences on the mental health of youth. (Read the full article)

Simulation-based education is increasing but its use in pediatric emergency medicine (PEM) fellowships has not been recently documented. Previous studies identified barriers including equipment and space, but growth of simulation centers and equipment has been widespread.

Simulation is widely used in PEM fellowships, and current barriers include faculty and learner time, implementation of best practices in simulation; equipment is less significant. Future work should focus on curriculum and evaluation development, aligning with the milestones. (Read the full article)

Low case volume has traditionally been associated with poor outcomes in complex surgical procedures, including pediatric liver transplantation.

This retrospective analysis supports the association between low case volume and poorer outcomes in pediatric liver transplantation, and, in addition, shows that candidates listed in low-volume centers have severely limited access to transplantation. (Read the full article)

Self-harm behavior is a major public health problem and a leading cause of death in adolescents. The majority of patients who self-injure do not die, but they are at increased risk for a successful future suicide attempt.

Emergency department visits for self-inflicted injuries in adolescents increased from 2009 to 2012, whereas visits for self-inflicted firearm injuries decreased. The presence of any comorbid condition increased risk for self-harm, indicating that increased attempts at prevention may be warranted in these young people. (Read the full article)

Almost half of NICUs include low birth weight (<2.5 kg) as an inclusion criterion for car seat tolerance screening (CSTS), formerly car seat challenges. However, little is known about incidence and risk factors for failure in this group.

This is the largest study to date evaluating the incidence and predictors of CSTS failure in full-term low birth weight neonates. Epidemiologic data are provided to help guide future CSTS policies and protocol development for this group. (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)

Breastfeeding provides a protective effect against some malocclusions, and there is a strong inverse correlation between the duration of breastfeeding and the duration of pacifier use.

The protective effects of predominant and exclusive breastfeeding against malocclusion are distinct: exclusive breastfeeding reduces the risk of malocclusions regardless of pacifier use, whereas the effect of predominant breastfeeding depends on the duration of the pacifier use.

Treatment of idiopathic steroid-resistant nephrotic syndrome is challenging, and therapeutic options are limited. In spite of good initial response with rituximab, responders always remain prone to further relapse, necessitating either repeat course of rituximab or addition of another steroid-sparing immunosuppressant.

Mycophenolate mofetil may be an effective maintenance therapy to consider as an additive immunosuppressant after induction with rituximab in maintaining remission among children with refractory steroid-resistant nephrotic syndrome. (Read the full article)

Previous research has described important variability in the medical evaluation of suspected child physical abuse. This variability may contribute to bias and reduce reliability in the medical diagnosis of abuse.

A panel of child abuse pediatricians participated in a Delphi Process, defining critical elements for the medical evaluation of suspected physical abuse in children. Results can be used to reduce practice variability that may contribute to potential bias in evaluation. (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)

The 2011 national guidelines for the management of pediatric community-acquired pneumonia recommended narrow-spectrum antibiotic therapy (eg, ampicillin) for most children hospitalized with pneumonia. Before the release of the guidelines, the use of broader-spectrum antibiotics (eg, third-generation cephalosporins) was much more common.

After release of the guidelines, third-generation cephalosporin use declined and penicillin/ampicillin use increased among children hospitalized with pneumonia. Changes were most apparent among institutions that proactively disseminated the guidelines, underscoring the importance of local efforts for timely guideline implementation. (Read the full article)

Gastrostomy tube placement is a difficult decision for families of children with neurologic impairment. Better understanding the impact of these tubes on the lives of children and families will help improve decision-making and support from health care providers.

Gastrostomy tube placement has broad-reaching implications for children and their families. There are physical, emotional, and relational challenges and benefits for the child, the parents, and the family unit. Exploring potential outcomes with families may improve decision-making conversations and support. (Read the full article)

The US Preventive Services Task Force recommends primary care clinicians apply fluoride varnish to the teeth of all young children, but no studies have examined the effect of comprehensive preventive oral health services on children’s clinical oral health status.

Comprehensive preventive oral health services delivered by primary care clinicians can help improve the oral health of Medicaid-enrolled children, but more work is needed to link medical and dental offices to ensure the continuity of dental care for these children. (Read the full article)

Medicaid made substantial investments in enhanced prenatal and postnatal care programs to address maternal and infant health, including infant mortality. Evaluations of population-based programs are few, and although some have reported reductions in infant mortality, they have methodological limitations.

A population-based home visitation program can be a successful approach to reduce infant mortality. The reduced risk of infant death is consistent with previous findings on the effects of the program on health care utilization and birth outcomes. (Read the full article)

More than 200 million children <5 years are not reaching their developmental potential. Lack of stimulating caregiving is a major cause, and effective scalable interventions are needed. Integrating parenting with health services has been recommended, but there are few evaluations.

An innovative parenting intervention can be delivered at routine visits for primary health care, with benefits to child cognitive development and parenting knowledge. This approach using films, discussion, and practice has the potential for delivery at scale. (Read the full article)

Although existing analyses of inpatient pediatric pulmonary hypertension (PH) care have established an association with substantial morbidity and mortality, these investigations have been limited to small single-institution series or focused registries representative of selected patient subgroups.

This study provides the first contemporary, national trend analysis of inpatient care for children with PH. Pediatric PH is associated with a rapidly increasing number of hospital discharges and magnitude of resource utilization, and the makeup of this population is changing. (Read the full article)

War-affected youth often suffer from multiple co-occurring mental health problems. The relationship of these conditions to later mental health has yet to be thoroughly investigated. There is a need to explore potential targets for mental health interventions.

After controlling for preexisting conditions and contemporary confounders, internalizing (depression and anxiety) remained the major predictor of future mental health symptoms (internalizing symptoms, prosocial attitudes/behaviors, and posttraumatic stress symptoms). Interventions targeting internalizing in war-affected youth hold promise. (Read the full article)

Infant screening is valued by members of the lay public, but how different benefits are independently valued, and whether harms are disvalued, is not known. Public expectations of screening can inform decisions about what diseases to screen for.

The public values clinical benefits of screening and disvalues harms, with tolerance for harm proportional to clinical benefit. These findings support newborn screening policies prioritizing clinical benefits over solely informational benefits, coupled with concerted efforts to avoid or minimize harms.

Neonatal coarctation of the aorta (CoA) is a life-threatening cardiac defect, but because symptoms may be lacking initially, newborns with this defect are frequently discharged from the hospital undiagnosed. Delayed diagnosis of CoA is associated with increased morbidity and mortality.

This population-based study analyzes the contribution of prenatal ultrasound and postnatal pulse oximetry screening to the timely diagnosis of neonatal CoA. Both screening methods had low sensitivity for CoA. Nearly half of all newborns with isolated CoA were discharged undiagnosed. (Read the full article)

Parents generally adapt well to newborn screening results, but reactions to carrier status for X-linked conditions are unknown.

Results suggest that detection and disclosure of FMR1 newborn carrier status may not result in significant adverse events for mothers. (Read the full article)

Biotinidase deficiency (BD) might cause severe and permanent consequences. Cases detected through newborn screening and under treatment are shown to remain asymptomatic. However, some countries, including Spain, do not provide universal BD screening within their national newborn screening programs.

It provides a first estimate of the lifetime costs and health outcomes of a Spanish birth cohort with and without neonatal screening for BD. It shows that newborn screening for BD is likely to be a cost-effective use of resources. (Read the full article)

Hospital quality-of-care measures are publicly reported to inform consumer choice and stimulate quality improvement. The number of hospitals and states with a sufficient number of pediatric hospital discharges to detect worse-than-average pediatric inpatient care quality remains unknown.

Most children are admitted to hospitals in which all-condition measures of inpatient quality are powered to show differences in performance from average, but most condition-specific measures are not. Policy on incentives for pediatric inpatient quality should take these findings into account. (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)

Studies on the risk of mortality and morbidities of extremely preterm infants of multiple gestation births have shown inconsistent results. Perinatal antecedents, admission status and severity of illness after birth can adversely affect outcomes of the extremely premature infants.

Preterm multiple gestation infants have increased risk of mortality but similar risk of major morbidities compared with singletons. Outcomes improved over time and all adverse outcomes, including mortality, were comparable between multiples and singletons in the most recent 5-year epoch. (Read the full article)

The etiology of juvenile idiopathic arthritis (JIA) is poorly understood. A recent study suggested a link between antibiotics and JIA but did not examine the potential for confounding from infections or the role of antibiotic timing.

Antibiotics were associated with newly diagnosed JIA in a dose- and time-dependent manner after adjusting for infection and other confounders. Antibiotics may play a role in the pathogenesis of JIA. (Read the full article)

Attitudes and knowledge about appropriate management of common childhood illnesses may lead parents to mistakenly believe antibiotics are needed. Differences existed in antibiotic knowledge and attitudes between parents of Medicaid- and commercially insured children and according to other sociodemographic variables.

Despite efforts to decrease unnecessary antibiotic use, misconceptions about antibiotic use persist and continue to be more prevalent among parents of Medicaid-insured children. Tailored efforts for socioeconomically disadvantaged populations remain warranted to decrease parental drivers of unnecessary antibiotic prescribing. (Read the full article)

Although treatment programs for childhood obesity can demonstrate success, long-term outcomes have seldom been evaluated. The benefit of intervention when overweight is identified in a screening assessment and parental recognition of the problem is minimal is understudied.

A low-dose (sessions every 1–3 months), but long-term (2 years), family-based intervention was effective at reducing BMI compared with usual care in children recruited via a weight screening initiative in which many parents had been unaware their child was overweight. (Read the full article)
