Stress affects health of children, potentially persisting as a trajectory into adulthood. Earlier biological markers assess only momentary stress, making it difficult to investigate stress over longer periods of time. Cortisol in hair is a new biomarker of prolonged stress.

Mother and child hair cortisol association suggests a heritable part or maternal calibration. Cortisol output gradually stabilizes, has a stable trait, and is positively correlated to birth weight. Hair cortisol is a promising noninvasive biomarker of prolonged stress, especially applicable for children. (Read the full article)

Caregiver behavioral symptom ratings are frequently used to assist in diagnosing childhood behavioral disorders. Although behavioral disorders are highly comorbid with learning disabilities (LDs), little work has examined the utility of caregiver ratings of learning concerns for screening of comorbid LD.

The validity of a time- and cost-efficient caregiver rating of academic concerns (Colorado Learning Difficulties Questionnaire) was examined. The screening measure accurately predicted children without LD, suggesting that the absence of parent-reported difficulties may be adequate to rule out overt LD. (Read the full article)

Prenatal exposures to diverse pollutants and psychosocial stressors have been shown independently to adversely affect child development. Less is known about the potential interactions between these factors, although they commonly co-occur, especially in disadvantaged populations.

The combination of high prenatal exposure to environmental polycyclic aromatic hydrocarbons and maternal demoralization adversely affects child behavior, and maternal demoralization has a greater effect among children with high prenatal polycyclic aromatic hydrocarbon exposure for a majority of behavioral symptoms.

Pediatric functional abdominal pain is common and costly. Cognitive behavior therapy (CBT) is a promising treatment for these complaints, but solid evidence for its effectiveness is lacking.

This randomized controlled trial shows that CBT reduces abdominal pain in 60% of children 1 year after treatment. Six sessions of CBT delivered by trained master’s students in psychology were equally effective as 6 visits to an experienced pediatrician. (Read the full article)

Previous studies have found links between prepregnancy BMI and/or pregnancy weight gain and autism spectrum disorders (ASD) risk. Several contributing factors to BMI and pregnancy weight gain (ie, prematurity, advanced maternal age, parental education, and parity) overlap with established ASD risk factors.

This study identifies an association between ASD risk and prenatal weight gain, but not prepregnancy BMI, and accounts for important confounding variables excluded in previous analyses. It provides the first within-mother comparison of these factors by including unaffected sibling controls. (Read the full article)

Levels of daily physical activity in children are decreasing worldwide. This implies risk factors for cardiovascular and metabolic diseases.

Strength training makes children not only stronger but significantly increases their daily spontaneous physical activity outside the training intervention. (Read the full article)

Certain characteristics of the sleep environment increase the risk for sleep-related, sudden, and unexplained infant death. These characteristics have the potential to generate asphyxia. The relationship between the deaths occurring in these environments and neurochemical abnormalities in the brainstem that may impair protective responses to asphyxia is unknown.

We report neurochemical brainstem abnormalities underlying cases of sudden infant death that are associated with and without potential asphyxial situations in the sleep environment at death. The means to detect and treat these abnormalities in infants at risk are needed. (Read the full article)

Use of behavioral health (BH) screens in pediatrics have increased identification of children with BH issues. Screening rates increased in Massachusetts after it was mandated, as did the volume of some mental health services.

This is the first study of children after Massachusetts mandated behavioral screening began. Almost 40% of children who screened positive were newly identified. Being male, having a BH history, and being in foster care predicted a positive screen. (Read the full article)

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

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

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

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

Despite widespread prevalence of vitamin D deficiency, there is a paucity of evidence on the appropriate supplemental dose in preterm infants. Various professional organizations empirically recommend different doses of vitamin D, ranging from 400 to 1000 IU per day.

Daily vitamin D supplementation at a dose of 800 IU compared with 400 IU significantly reduces the prevalence of vitamin D deficiency in preterm infants. The clinical significance of achieving vitamin D sufficiency needs to be studied in larger trials. (Read the full article)

Greater numbers of invasive procedures from birth to term-equivalent age, adjusted for clinical confounders, are associated with altered brain microstructure during neonatal care and poorer cognitive outcome at 18 months’ corrected age in children born very preterm.

Altered myelination at school age is associated with greater numbers of invasive procedures during hospitalization in very preterm children without severe brain injury or neurosensory impairment. Greater numbers of invasive procedures and altered brain microstructure interact to predict lower IQ. (Read the full article)

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)

After mild traumatic brain injury, most youth recover well. A minority of patients report persistent symptoms, which relate to both injury and noninjury factors. In adult studies, validity test performance is 1 noninjury factor that relates to persistent symptoms.

This is the first pediatric study to demonstrate that validity test failure is associated with increased symptoms after mild traumatic brain injury. The findings suggest that some symptoms conceptualized as injury-related "postconcussive" problems are better explained by exaggeration or feigning. (Read the full article)

Motor vehicle crashes, heavy drinking, and drug use are serious, interactive health concerns for the teenage population. Teenage alcohol-impaired driving behaviors are associated with heavy drinking, parenting practices, and exposure to drinking and driving.

Earliness of exposure to alcohol/drug impaired driving (DWI) and early licensure were independent risk factors for teenage DWI. A strong, positive dose-response existed between DWI and amount of prior exposure to DWI in the form of riding with an impaired driver. (Read the full article)

The period of transition from childhood to adulthood and the period immediately after transfer of care is a challenging time for young people with kidney failure.

Young patients with kidney failure cared for exclusively in adult-oriented facilities experience increased rates of avoidable hospitalizations during late adolescence and young adulthood. Avoidable hospitalizations increased among pediatric kidney failure patients during the years immediately after transfer to adult care. (Read the full article)

Ceftriaxone at therapeutic doses can lead to renal stone formation.

Renal stone formation with ceftriaxone therapy can result in postrenal acute renal failure in children. The condition can be treated effectively by timely pharmacotherapy or retrograde ureteral catheterization with good prognosis. (Read the full article)

Approximately 20% of US child passenger deaths involve an alcohol-impaired driver, typically in the child’s own vehicle. The higher the blood alcohol concentration of a driver, the more likely his or her child passenger was unrestrained in the fatal crash.

The risk of a child passenger dying while being transported with an alcohol-impaired driver varies meaningfully across states. These state-specific rates may help to inform renewed prevention efforts. (Read the full article)

Children receive only half of recommended health care; disadvantaged children have higher risk of unmet needs. Practice coaching combined with quality improvement using rapid-cycle feedback has potential to help practices meet quality standards and improve pediatric health care delivery.

The Practice-tailored Facilitation Intervention led to large and sustained improvements in preventive service delivery, including substantial numbers of disadvantaged children, and in multiple simultaneous health care domains. Practice-tailored facilitation holds promise as a method to advance pediatric preventive care delivery. (Read the full article)

Preterm birth is strongly associated with alterations in brain development and long-term neurocognitive impairment that are not fully explained by environmental factors.

Common genetic variation in genes associated with schizophrenia and lipid metabolism modulates the risk for preterm brain injury; known susceptibilities to neurologic disease in later life may be exposed by the stress of preterm birth. (Read the full article)

Curtailed sleep in children has been found to be associated with increased cardiovascular disease risk factors, including obesity. Few existing studies have examined measures of adiposity beyond BMI or have examined the effects of being chronically sleep curtailed.

In this cohort of children who had research-level measures of sleep, BMI, total fat mass, and fat mass distribution, we found that chronic sleep curtailment from infancy to age 7 years was associated with higher overall and central adiposity in mid-childhood. (Read the full article)

Food insecurity is best measured by comprehensive assessments. However, rapid assessments can be useful in certain circumstances, but their validity is not characterized.

Rapid assessment of food insecurity is feasible among Inuit adults and children. (Read the full article)

Demographic data concerning health care providers working long-term in resource-limited areas with religious groups or other government or nongovernment organizations are limited. Health outcomes from these programs vary with the focus of the individual program.

This study describes the composition and evaluation of a long-term global health corps program. Other groups interested in long-term physician placement in resource-limited areas will be able to use these data while developing their program. (Read the full article)

Previous analyses have documented that the prevalence of children with chronic conditions is growing and is responsible for increased growth in hospital charges; however, such utilization trends have not been documented in Medicaid and the Children’s Health Insurance Program.

From 2007 through 2010 in Illinois, children with chronic conditions became Medicaid and Children’s Health Insurance Program recipients at a higher rate than healthy children. In contrast to studies of hospital data, this analysis found per-member spending decreases in most chronic condition groups. (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)

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)

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)

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)

High-fidelity simulation improves individual skills in neonatal resuscitation. Usually, training is performed in a simulation center. Little is known about the impact of in situ training on overall team performance.

In situ high-fidelity simulation training of 80% of a maternity’s staff significantly improved overall team performance in neonatal resuscitation (technical skills and teamwork). Fewer hazardous events occurred, and delay in improving the heart rate was shorter. (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)

Pediatric primary care has undergone a cultural shift. Changes in electronic health records, certification requirements, and practice structure have left many physicians feeling too busy to participate in research. Practice-based research networks must adapt to fit the current climate.

Adding quality improvement activities that meet Maintenance of Certification Part 4 criteria to research study design adds value to a practice-based research protocol. This incentive meets the needs of busy physicians, and may help researchers meet study recruitment goals. (Read the full article)

The fetal origins of adult disease hypothesis proposes that suboptimal fetal development may condition the later risk of disease, particularly cardiovascular disease. However, this hypothesis has never been tested for diseases of the aging brain.

This first study of its kind provides clinical measures suggesting that small birth size, as an indicator of an adverse intrauterine environment, has lifelong consequences for brain tissue volume and cognitive function. In addition, it shows that the effects of a suboptimal intrauterine environment on late-life cognitive function were particularly present in those with lower educational levels.

Lung ultrasound outperforms conventional radiology in the emergency diagnosis of pneumothorax and pleural effusions. In the pediatric age, lung ultrasound has been also successfully applied to the fluid-to-air transition after birth and to rapid pneumonia diagnosis.

Nasal ventilation has dramatically decreased the need for invasive mechanical respiratory support. This study demonstrates that, after a short trial on nasal continuous positive airway pressure, lung ultrasonography reliably predicts the failure of noninvasive ventilation unlike the conventional chest radiogram.

Behavioral health (BH) screening is known to increase identification of children with BH issues, but in small-scale studies, rates of follow-up after screening have been reported to be low.

This study examines the relationship between BH screening and the receipt of BH services in Massachusetts Medicaid children. Nearly 60% of children identified with BH problems received BH services, but only 30% of newly identified children received BH services. (Read the full article)

Physical activity programs have been shown to have positive implications for children’s cognitive performance and brain structure and function. However, additional randomized controlled trials are needed to determine whether daily physical activity influences executive control and its neural underpinnings.

The randomized controlled trial, designed to meet daily physical activity recommendations, used behavioral and electrophysiological measures of brain function to demonstrate enhanced attentional inhibition and cognitive flexibility among prepubertal children. (Read the full article)

Parental smoking cessation helps eliminate children’s exposure to tobacco smoke. A child’s visit to the doctor provides a teachable moment for parental smoking cessation. Effective strategies to help parents quit smoking are available for implementation.

Evidence-based outpatient intervention for parents who smoke can be delivered successfully after the initial implementation. Maximizing parental quit rates in the pediatric context will require more complete and sustained systems-level integration. (Read the full article)

Preterm birth and faster infant growth have been identified as independent risk factors for autism-spectrum disorders (ASD). However, associations between prematurity and ASD-related traits as a continuum and effects of infant growth among those born preterm are still little studied.

VLBW young adults reported higher levels of ASD-related traits, particularly traits related to poorer social skills. Within the VLBW group, faster growth in weight, height, and head circumference from birth to term was associated with lower levels of ASD-related traits. (Read the full article)

Although we know breastfeeding is beneficial and infant weight gain can predict obesity later in life, the relationship between breastfeeding duration and infant weight gain patterns among populations exhibiting high risk for obesity is unexplored.

This study demonstrates the greater odds of increased infant weight gain for infants who breastfed for shorter durations among those exposed to a high number of maternal biopsychosocial risk factors for obesity. (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)

Sustained lung inflation and positive end-expiratory pressure would permit lung recruitment immediately after birth, improving lung mechanics and reducing the need for respiratory support. Previous clinical studies in preterm infants provided promising results but have some limitations.

This randomized controlled study found that prophylactic sustained lung inflation and positive end-expiratory pressure in the delivery room decreased the need for mechanical ventilation in the first 72 hours of life in preterm infants at high risk of respiratory distress syndrome.

Migraine headaches are a common presenting complaint in emergency departments. Abortive treatment in this setting is not well studied, leading to considerable variation in treatment. The relationship between acute medications and emergency department revisits has not been studied.

Eighty-five percent of children with migraine are successfully discharged from the emergency department; only 1 in 18 children require a return visit. Prochlorperazine is associated with less revisits than metoclopramide, and diphenhydramine use is associated with increased risk of return visits. (Read the full article)

Although headache is a common symptom after minor blunt head trauma in children, controversy exists whether the presence of headache increases the risk of traumatic brain injury.

Clinically important traumatic brain injuries are rare, and traumatic brain injuries on computed tomography are very uncommon in children with minor blunt head trauma when headaches are their only sign or symptom. (Read the full article)

Little is known about the impact of tobacco smoke exposure on preterm children with bronchopulmonary dysplasia. It is essential to understand how environmental exposures, such as tobacco smoke, influence respiratory morbidities in this vulnerable population.

Chronic tobacco smoke exposure is common in children with bronchopulmonary dysplasia. In children who required home respiratory support, hair nicotine levels were a better predictor of hospitalization and activity limitation than caregiver self-report. (Read the full article)

Patients with sickle cell disease frequently express dissatisfaction with emergency department treatment of painful crises. Time to opioid administration has been suggested as a quality of care measure for painful crises.

Although not associated with hospital admission, time to opioid administration in sickle cell disease painful crises was associated with secondary outcomes including improvement between the first 2 pain scores, decreased pain score area under the curve at 4 hours, decreased emergency department length of stay, and increased total opioids.

Although the rates of antipsychotic medication treatment are rising for children and adolescents, little is known about the factors associated with this practice.

This study provides some of the first data regarding when and why clinicians decide to use antipsychotic medications. It reveals clues as to how prescribing might better follow best practice guidelines. (Read the full article)

Early-life lower respiratory illnesses, including pneumonia, are associated with increased prevalence of asthma and diminished lung function in children. Whether early-life pneumonia is associated with subsequent impaired lung function and asthma in adults is not yet clear.

This is the first article providing strong data for an association between early-life pneumonia in an outpatient setting and airflow limitation and asthma into adulthood, supporting the hypothesis of the early-life origins of chronic obstructive pulmonary disease. (Read the full article)

The diversifying US population has led to the examination of workforce diversity and training. National data on diversity, inclusion, and cultural competency training have been previously collected but have been assessed only at the macro level of medicine.

This study assesses workforce diversity, inclusion, and cultural competency training in departments of pediatrics across the country and provides the first assessment of departmental efforts to improve diversity and inclusion and provide cultural competency training to trainees and faculty.
