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.

Severe complications, such as respiratory failure, have been described in influenza infection. Clinicians are commonly faced with influenza-like illnesses (ILI), which is the initial nonspecific presentation of many respiratory viruses; the risk of severe complications from ILI are unknown.

Severe complications occurred in children initially presenting with ILI, irrespective of the virus identified. Risk factors for severe complications did not differ by demographics or respiratory virus, although children with high-risk conditions are at greater risk of severe complications.

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

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

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

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

Puberty suppression has rapidly become part of the standard clinical management protocols for transgender adolescents. To date, there is only limited evidence for the long-term effectiveness of this approach after gender reassignment (cross-sex hormones and surgery).

In young adulthood, gender dysphoria had resolved, psychological functioning had steadily improved, and well-being was comparable to same-age peers. The clinical protocol including puberty suppression had provided these formerly gender-dysphoric youth the opportunity to develop into well-functioning young adults. (Read the full article)

The single-family room (SFR) NICU is a major response to improve care and reduce developmental morbidity in preterm infants. However, no studies have examined how and why this model is associated with changes in medical and neurobehavioral outcome.

This study shows improved medical and neurodevelopmental outcome in infants hospitalized in the SFR model of care. More important, improvements occurred specifically in relation to increases in maternal involvement and developmental support afforded by the SFR environment. (Read the full article)

Children who have attention-deficit/hyperactivity disorder (ADHD) attending clinical services have poorer outcomes in adolescence on a range of measures. However, it is unknown how early in development these impairments appear, particularly for community-ascertained samples.

At age 6 to 8 years, children in the community with ADHD have significantly poorer mental health, academic performance and social function compared with control children. Children who have impairing ADHD symptoms should be referred early for assessment and intervention. (Read the full article)

Little is known about how pediatricians communicate with overweight Latino children and their parents regarding overweight and obesity.

Findings suggest that many overweight Latino children and their parents do not receive direct communication that the child is overweight, weight-management plans, culturally relevant dietary recommendations, or follow-up visits. (Read the full article)

Quality improvement (QI) studies generally do not account for concurrent trends of improvement and it is difficult to distinguish the impact of a multihospital collaborative QI project without a contemporary control group.

A multihospital collaborative QI model led to greater declines in hypothermia and invasive ventilation rates in the delivery room compared with an individual NICU QI model and NICUs that did not participate in formal QI activities. (Read the full article)

Perinatal complications predict increased risk for morbidity and early mortality. Evidence of perinatal programming of adult mortality raises the question of what mechanisms embed this long-term effect. Telomere length and perceived facial age are 2 indicators of accelerated aging.

Perinatal complications predicted greater signs of accelerated aging "inside," as measured objectively by leukocyte telomere length, an indicator of cellular aging, and "outside," as measured subjectively by perceived age, an indicator of declining integrity of tissues. (Read the full article)

In 2000/2001, the American Academy of Pediatrics published recommendations for attention-deficit/hyperactivity disorder (ADHD) care. According to pediatricians’ self-report of adoption of these guidelines, community-based ADHD care appears to be marginally adequate.

Using reviews of >1500 patient charts, this study demonstrates that community-based ADHD care is not consistent with evidence-based practice. Furthermore, variability in much of community-based ADHD care is unrelated to the provider, suggesting that innovative, system-wide interventions are needed to improve ADHD care.

Neurodevelopment can be adversely affected by viral infections. Human herpesvirus-6 (HHV-6) is similar to cytomegalovirus and can cause central nervous system disease. Congenital HHV-6 infection occurs in ~1% of live births, with unknown neurodevelopmental consequences.

HHV-6 congenital infection is associated with lower scores on the Bayley Scales of Infant Development II Mental Development Index compared with control infants at 12 months of age and may have a detrimental effect on neurodevelopment. (Read the full article)

Youth in foster care are at higher risk of health problems at entrance and during their stays in care. Little is known about this group’s risk of health problems in young adulthood, in comparison with other populations of young adults.

This is the first prospective study to our knowledge demonstrating that former foster youth are at higher risk of chronic health problems than economically secure and insecure general population young adults. (Read the full article)

Studies have shown that reciprocal vocalizations between mother and infant have positive effects on language development. It has been shown that girls acquire vocabulary and language skills earlier than boys.

Mothers more readily respond to their infant’s vocal cues than fathers, and infants show a preferential vocal response to their mothers in the first months of life. Mothers respond preferentially to infant girls versus boys at birth and 44 weeks. (Read the full article)

IP-10 is a novel immunologic marker for tuberculosis (TB) infection. It has been suggested that IP-10 may perform better in children compared with the QuantiFERON test, but only a few studies have investigated IP-10 for diagnosing active TB in children.

This study is the first to investigate IP-10 and QuantiFERON for diagnosing TB in children by using consensus classifications. Both IP-10 and QuantiFERON exhibited poor performance in children from a high-burden setting, and performance was especially compromised in young children. (Read the full article)

White matter abnormality (WMA) on neuroimaging is considered a crucial link with adverse neurodevelopmental outcome in preterm infants. Brain MRI is more sensitive in detecting WMA than cranial ultrasound (CUS), but questions remain about timing and prognostic value of modalities.

Near-term CUS and MRI abnormalities were associated with adverse 18- to 22-month outcomes, independent of early CUS and other factors, underscoring the relative prognostic value of later neuroimaging in this large, extremely preterm cohort surviving to near-term. (Read the full article)

Prenatal alcohol exposure can cause congenital neuropsychological and behavioral disabilities in later life. These usually lead to secondary disabilities (adverse outcome when the individual interacts with environmental settings), such as problems with school, the law, alcohol, or drugs.

This was a 30-year psychosocial register–based follow-up on adults with fetal alcohol syndrome and state care comparison group. The FAS-group had lower education and higher rates of unemployment, social welfare, and mental health problems than peers. Rates of criminality did not differ. (Read the full article)

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)

US children consume excessive amounts of sodium and substantial amounts of added sugars. Early life exposures to salt and sugar can set taste preferences and health trajectories.

A substantial proportion of toddler meals and other commercial foods meant for children age ≥12 months are of potential concern because of their high sodium content or presence of ≥1 added sugar. (Read the full article)

Medical home transformation is led by practice-level assessment, but much of the evidence supporting the medical home derives from individual-level assessment based on parental perception. The association between these 2 levels of assessment is unknown.

Among Boston-area community health centers, there was no association between the individual- and practice-level assessments of the medical home. This highlights the need for studies supporting the child health benefits of medical home practice transformation. (Read the full article)

Universal use of conjugated pneumococcal vaccines has resulted in dramatic decline in vaccine-type invasive pneumococcal disease. However, disease is not evenly distributed, and children with underlying clinical conditions are disproportionately represented, especially among children >5 years of age.

Invasive pneumococcal disease among children with comorbidity results in higher morbidity and mortality, and a large proportion of disease is due to serotypes not included in current conjugate vaccines. (Read the full article)

Obstructive sleep apnea syndrome (OSAS) is associated with significant comorbidity: behavioral problems, sleepiness, and impaired quality of life. However, the utility of OSAS symptoms versus polysomnography in the prediction of comorbidities or response to treatment is not well known.

Among children with OSAS, the Pediatric Sleep Questionnaire, a well-validated, simple 1-page symptom inventory, predicts key adenotonsillectomy-responsive OSAS comorbidities and their improvement after adenotonsillectomy. In contrast, polysomnographic results do not offer similar predictive value. (Read the full article)

Previous studies have demonstrated racial and ethnic differences in glycemic control even after adjustment for variables such as insulin dosage, diabetes duration, and socioeconomic status. It is controversial whether genetic, physiologic, cultural, socioeconomic, and/or provider-related factors underlie these disparities.

This study in a large, racially/ethnically diverse sample of children with type 1 diabetes demonstrates that racial disparities in insulin treatment methods and diabetes outcomes remain even after adjustment for socioeconomic status. (Read the full article)

Surviving infants with neonatal encephalopathy treated with hypothermia have lower rates of moderate to severe cerebral palsy and cognitive impairment at 18 to 24 months. Limited data exist on the association between cognitive functioning and neuromotor, behavioral, and school outcomes.

Although the incidence of death or IQ <55 is reduced after therapeutic hypothermia, survivors of neonatal encephalopathy with and without cerebral palsy are at elevated risk for subnormal IQ and the need for specialized educational services at 6 to 7 years. (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)

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)

Although there is evidence regarding comorbidity of physical and mental disorders from clinical samples of specific disorders and treatment registries, there is limited evidence from systematic samples of youth with comprehensive information on the full range of mental and physical disorders.

This report is the first study to investigate the specificity of associations between a broad range of mental and physical conditions by using a large, systematically obtained pediatric sample with enriched information from electronic medical records and direct interviews. (Read the full article)

Functional capabilities in patients with spina bifida depend on the spinal level of the lesion and its type. Sociodemographic characteristics have been shown in other conditions to be an important additional influence on outcomes, making them important for risk adjustment.

Males, non-Hispanic blacks, and patients without private insurance have less favorable functional outcomes in spina bifida, and age also has an impact. These attributes need to be considered by clinicians and researchers and used in comparing care outcomes across clinic settings. (Read the full article)

Children with special health care needs are a growing population in developed countries. They are at risk for poorer learning and behavioral outcomes, and their parents are more likely to have poorer mental health.

Four distinct and replicable special health care need profiles across 2 childhood epochs were categorized as none, transient, emerging, and persistent. The cumulative burden of special health care needs shaped adverse outcomes more than did point prevalence. (Read the full article)

Blood cultures are the most widely available diagnostic tool to identify bacterial pathogens in community-acquired pneumonia (CAP). Despite a recent national guideline recommendation for blood culture performance in children with moderate/severe CAP, there is still wide variation across institutions.

Using improvement methodology, we demonstrated that blood cultures can be routinely performed in children admitted for CAP, in accordance with a recent national guideline, without increasing length of stay in a setting with a low false-positive blood culture rate. (Read the full article)

Encephalitis is a serious and disabling condition. There are infectious and immune-mediated causes of encephalitis, but many cases remain undiagnosed.

This large single-center study on childhood encephalitis provides insight into the relative frequency and clinicoradiologic phenotypes of infectious, autoantibody-associated, and unknown encephalitis. Risk factors for an abnormal outcome are also defined. (Read the full article)

Collaborative care is known to be an effective system to manage child behavioral health conditions in the primary care setting.

Among urban children with attention-deficit/hyperactivity disorder, using lay care managers to address barriers to engagement with care and challenging child behaviors has the potential to improve the effectiveness of conventional collaborative care. (Read the full article)

Pediatric residents may not be achieving competency in neonatal intubation. Opportunities for intubation during residency are decreasing. A precise definition of competency during training is lacking.

Bayesian statistics may be used to describe neonatal intubation competency in residents. At least 4 successful intubations are needed to achieve competency. The first 2 intubation opportunities appear to predict how many intubation opportunities are ultimately needed to achieve competency. (Read the full article)

Although opioid pain relievers are commonly prescribed in pregnancy, their association with neonatal outcomes is not well described. Further, factors associated with development of neonatal abstinence syndrome, a neonatal opioid withdrawal syndrome is inadequately understood.

Prescription opioid use in pregnancy is common and strongly associated with neonatal complications. Antenatal cumulative prescription opioid exposure, opioid type, tobacco use, and selective serotonin reuptake inhibitor use increase the risk of neonatal abstinence syndrome. (Read the full article)

Mortality rates and health care expenditures are high among infants requiring surgery for necrotizing enterocolitis. The impact of different surgical managements on mortality remains equivocal. Adjusted economic differences for various surgical treatments may exist but have not been elucidated.

After performing a relatively large-scale, adjusted analysis of cost and mortality for surgical managements currently used for treating necrotizing enterocolitis, a cost-benefit for a particular surgical approach was demonstrated while accounting for comorbidities and group assignment bias.

Timely immunoprophylaxis and completion of the 3-dose hepatitis B vaccine series represents the cornerstone of perinatal hepatitis B prevention. Immunoprophylaxis for infants born to hepatitis B surface antigen–positive mothers reduces up to 95% of perinatal hepatitis B virus infections.

Despite recommended immunoprophylaxis, perinatal hepatitis B virus infection occurs among ~1% of infants. Infants born to mothers who are younger, hepatitis B e-antigen positive, or who have a high viral load or infants who receive <3 hepatitis B vaccine doses are at greatest risk of infection. (Read the full article)

Considerable differences in outcome after extremely preterm birth have been reported between centers and regions providing a comparative level of care, but the reasons for these variations have been poorly examined.

In extremely preterm fetuses alive at the mother’s admission for delivery, and in infants born alive, mortality up to 2.5 years is reduced in regions with a more active use of perinatal interventions without increased neurodevelopmental morbidity. (Read the full article)

Neonatal arterial ischemic stroke is associated with later cerebral palsy and cognitive impairment. Many studies on neonatal ischemic stroke are limited by modest sample sizes, and prospective studies that include outcomes assessments are scarce.

Results from this prospective, nationwide, population-based study provide information on the epidemiology, associated clinical variables, clinical manifestation, vascular distribution, and treatment of neonatal arterial ischemic stroke. The study also provides outcomes regarding motor function and cognition. (Read the full article)

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)

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)

The Respiratory Distress Assessment Instrument (RDAI) and the Respiratory Assessment Change Score (RACS) are the most frequently used measurement instruments in bronchiolitis clinical trials. Evidence is scarce regarding their measurement properties and their suitability for use as evaluative instruments in clinical trials.

The RDAI is an incomplete measure of respiratory distress in bronchiolitis, with poor to moderate construct validity. It has adequate discriminative properties but considerable test-retest measurement error. The RDAI and RACS were moderately responsive, but methodologic issues limit the interpretation of this finding. (Read the full article)

Microcephaly is known to be associated with neurocognitive disorders and increasing head size with hydrocephalus. Head circumference is widely measured in childhood, but its practical value as a screening test is unclear.

Measured head size is not a stable characteristic and centile shifts occur very commonly, mostly reflecting measurement error or regression to the mean. Even where head size was consistently extreme, it was not a good predictor of later developmental problems. (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)

Pediatric patients suffer higher mortality due to the shortage of transplantable organs. Factors influencing families’ donation decisions are similar for pediatric and adult patients. However, the general perception that families of pediatric patients are less willing to donate persists.

Communication emerged as a critical factor of family authorization, reinforcing its importance in the organ donation process. Patient age (ie, adult versus pediatric) was not predictive of family authorization. (Read the full article)

Tonsillectomy guidelines make evidence-based recommendations for the perioperative use of dexamethasone, no routine use of antibiotics, and discharge education of families and for surgeons to monitor bleeding complication rates. The impact of the guidelines on processes and outcomes is unknown.

The guidelines were associated with improvement in perioperative care processes but no improvement in outcomes. Perioperative dexamethasone use increased slightly, and antibiotic use decreased substantially. Bleeding rates were stable, but revisit rates for complications increased because of revisits for pain.

There has been increasing legislative and regulatory focus on the relationships of pediatric prescribers and industry. Pediatric professional medical association (PMA) and industry relationships, however, are relatively unstudied and lack a systematic method of assessment.

This cross-sectional study used a new quantitative scale, the industry relationship index, to systematically rate 9 pediatric PMAs with respect to best practice guidelines on interactions with the biomedical industry, revealing significant variation in PMA practices. (Read the full article)

Late preterm infants, compared with full-term infants, have less proficiency in reading and math at school age, with increased need for individualized educational plans and special education services. They also have lower cognitive performance on standardized IQ exams.

Late preterm infants have worse outcomes at school entry, and development is variable during the preschool years, so socioeconomic status, language spoken in the home, maternal education, maternal race, and being a late preterm infant have a large impact. (Read the full article)

Unmet health care need in adolescence is associated with poor contemporaneous health outcomes. Adolescence is increasingly recognized as an important stage of the life-course, when there may be a significant opportunity for health care interventions to improve later health outcomes.

The odds of adverse adult health outcomes were 13% to 52% higher among subjects who had reported unmet health care need in adolescence, compared with subjects with similar adolescent health outcomes, insurance coverage, and sociodemographic background but no unmet need. (Read the full article)
