The diagnosis of urinary tract infection (UTI) is confirmed by urine testing with urinalysis and culture. No study has characterized the use of urine testing in the setting of empirical antibiotic prescription for outpatient UTI in children.

Urine tests are not performed in a substantial percentage of antibiotic-treated pediatric UTIs. Additional research is necessary to determine whether empirical antibiotic prescription for UTI in children without urine testing is safe and effective. (Read the full article)

Respiratory outcomes of patients with bronchopulmonary dysplasia (BPD) range from no oxygen requirement to chronic respiratory failure. Outcomes of least severe types of BPD are well described. Limited data exist on outcomes of patients with BPD-related chronic ventilator dependency.

Along with a first estimation of the incidence of patients with severe BPD-related chronic respiratory failure who were dependent on positive pressure ventilation via tracheostomy at home, we describe their survival rate, liberation from positive pressure ventilation, and decannulation.

Asthma is a common medical complication during pregnancy that is associated with an increased risk of adverse obstetric outcomes.

This study adds knowledge on potential long-term consequences of maternal asthma during pregnancy for offspring health, demonstrating that maternal asthma during pregnancy is linked to a wide spectrum of offspring diseases during childhood. (Read the full article)

Bronchopulmonary dysplasia is associated with increased long-term neurodevelopmental and respiratory morbidity. Inhaled nitric oxide given to reduce morbidity in very preterm infants does not reduce the prevalence of bronchopulmonary dysplasia and has uncertain effects on long-term outcome.

Inhaled nitric oxide (5 ppm) given early in the course of respiratory illness in infants born before 29 weeks of gestation is not associated with changes in developmental or respiratory outcomes at 2 years of age corrected for prematurity. (Read the full article)

The number of overweight and obese children has dramatically increased in recent decades. To combat this trend, information on possible gender-related differences in risk factors of overweight and obesity is critical.

This study examines associations of gender and physiologic and behavior measurements with potential cardiovascular risk. Lunch consumption and screen time were associated with weight; however, other associations with weight differ by gender. This information can be used to tailor future interventions.

Evaluating for elevations in alanine aminotransferase (ALT) is a common screening test for the presence of nonalcoholic fatty liver disease (NAFLD). NAFLD is less common among non-Hispanic blacks. Better predictors of NAFLD are needed to identify individuals in most need of screening.

Relative to other ethnicities, metabolic syndrome and insulin resistance performed poorly at identifying non-Hispanic black adolescents with ALT elevations. The presence of metabolic syndrome may therefore not be an adequate trigger for NAFLD screening. Triglyceride elevations performed similarly between groups in identifying ALT elevations.

Pulse oximetry screening at 24 hours of age improves detection of critical congenital heart disease in asymptomatic newborns.

This study describes an initial experience with pulse oximetry screening for critical congenital heart disease and provides a strategy for preparing for state implementation of recent federal newborn screening recommendations. (Read the full article)

Only 2 randomized controlled trials have addressed effects of ultrasound screening for developmental hip dysplasia. Both concluded that adding universal or selective ultrasound to routine clinical examination gave a nonsignificant reduction in rates of late presenting cases, but higher treatment rates.

This maturity review assesses long-term outcome of one of these trials. Rates of radiographic findings indicating acetabular dysplasia and degenerative change were similar across the 3 screening groups in young adulthood. Increased treatment rates were not associated with avascular necrosis. (Read the full article)

Phthalate exposure has been associated with insulin resistance in animal studies and cross-sectional studies of adults, but has not been studied in adolescents.

We detect associations of urinary phthalate metabolites in a cross-sectional study of US adolescents. The association is highly robust to multiple sensitivity analyses, and specific to phthalates commonly found in food. Further longitudinal study of dietary phthalate exposures is needed.

Effective implementation of Pediatric Emergency Care Applied Research Network head trauma rules depends on their early application. As the registered nurse (RN) is often the first to evaluate children with blunt head trauma, initial RN assessments will be an important component of this strategy.

We demonstrated fair to moderate agreement between RN and physician providers in the application of the Pediatric Emergency Care Applied Research Network head trauma rules. Effective implementation strategies may require physician verification of RN predictor assessments before computed tomography decision-making. (Read the full article)

The incidence of pediatric pneumococcal meningitis has declined after introduction of the 7-valent pneumococcal conjugate vaccine (PCV7). It is unknown whether the frequency of severe neurologic sequelae and adverse outcomes has changed in the era of widespread PCV7 use.

Pneumococcal meningitis continues to be associated with substantial mortality and long-term morbidity. Sixty-three percent of survivors had neurologic sequelae. More than one-half of the children who were eligible for PCV7 were unimmunized at the time that they developed pneumococcal meningitis. (Read the full article)

Term neonates in resource-poor settings frequently develop hypothermia. Plastic bags or wraps are a low-cost intervention for the prevention of hypothermia in preterm and low birth weight infants that may also be effective in term infants.

For term neonates born in a resource-poor health facility, placement in a plastic bag at birth can reduce the incidence of hypothermia at 1 hour after birth. (Read the full article)

Readmissions have been identified as a priority area for pediatric inpatient quality measurement nationally. However, it is unknown whether readmission rates vary meaningfully across hospitals and how many hospitals would be identified as high- or low-performers.

Only a few hospitals that care for children are high- or low-performers when their condition-specific revisit rates are compared with average rates across hospitals. This limits the usefulness of condition-specific readmission or revisit measures in pediatric quality measurement. (Read the full article)

Previous studies have reported that former late preterm infants are at increased risk for future learning and behavioral problems; thus it has been suggested that their development be closely monitored.

This population-based study indicates that the risk for attention deficit/hyperactivity disorder and learning disabilities may not be higher in former late preterm infants, and therefore intensive neurodevelopmental follow-up may not be required for all late preterm infants. (Read the full article)

The Faces Pain Scale–Revised and Color Analog Scale are self-report pain scales that are commonly used for children in the clinical and research settings.

The Faces Pain Scale–Revised and Color Analog Scale overall demonstrate strong psychometric properties in children 4 to 17 years of age, including within subgroups of age, sex, and ethnicity. Convergent validity, however, is questionable in children <7 years old. (Read the full article)

Shared decision-making involves the assessment of preferences and goals and has been prioritized in new attention-deficit/hyperactivity disorder treatment guidelines, yet no studies have examined the impact of both preferences and goals on treatment initiation.

Supporting the clinical utility of preference and goal assessment, we found that parental treatment preferences are associated with treatment initiation, and those with distinct goals select different treatments. (Read the full article)

Parents of premature infants are susceptible to developing trauma symptoms related to their NICU experience. There are no current well-established interventions that simultaneously address both parental trauma as well as redefinition of the parenting experience.

A brief, cost-effective, and feasible manualized intervention for NICU parents was effective in reducing both parental trauma and depression. Implementation of this intervention in the NICU setting has the potential to improve maternal well-being and infant outcomes. (Read the full article)

Adult males are known to have a greater overall likelihood of death than female adults. Among children, excess male mortality is known for specific conditions but not as a general phenomenon.

Males are more likely to die during childhood and adolescence than their female peers from not only injuries but also from a wide variety of medical conditions, suggesting the existence of either a female robustness factor or a male vulnerability factor. (Read the full article)

Rehabilitation of people with cerebral palsy aims to achieve and maintain optimal performance in mobility and daily activities. Although insight into the developmental trajectories of activities from childhood into adulthood is important, little is known about long-term development.

The gross motor function of children with cerebral palsy determines the developmental trajectories of mobility performance but not of daily activities, where intellectual disability was shown to be the determining factor. (Read the full article)

Pediatric early warning scores (PEWS) for hospital inpatients have been developed to identify patients at risk for deterioration. Beyond triage, similar systems that identify ill patients and predict requirements for a higher level of care are needed in the emergency department.

The validity of the different PEWS in pediatric emergency care patients has never been evaluated. This study showed that PEWS are capable of detecting children in need of ICU admission. (Read the full article)

Several studies have suggested that probiotics may prevent necrotizing enterocolitis and death in preterm infants. However, there are no data on the preventive effect of probiotics in infants with cyanotic congenital heart disease.

Although duration of hospitalization was not significantly decreased, Bifidobacterium lactis plus inulin appears to decrease the rate of nosocomial infection, necrotizing enterocolitis, and death in infants with cyanotic congenital heart disease. (Read the full article)

The prevalence of overweight and obesity in US adolescents has increased over the last century. However, recent evidence indicates a potential change in this trend. Parallel trends in adolescent behaviors that drive this epidemic have not been well studied.

Analyses of recent data indicate the prevalence of overweight and obesity may be stabilizing. Over the same period, adolescent physical activity, breakfast eating, and fruit and vegetable consumption increased and television viewing and consumption of sweets and sweetened beverages decreased.

Health insurance is associated with improved health for children, but gay and lesbian parents face barriers to adding their children to private health insurance. Little is known about the extent to which insurance disparities exist for children with same-sex parents.

Children with same-sex parents are less likely to have private health insurance. When children live in states in which legal same-sex marriage, civil unions, domestic partnerships, or second-parent adoptions are available, disparities in private insurance diminish for children with same-sex parents.

Preschool language delay is associated with poorer academic performance, more limited employment opportunities, and relationship difficulties. Despite its importance within public health, there has been little progress toward effective population-based prevention and intervention approaches to improve outcomes.

It is feasible to identify low language in 4-year-olds on a population basis and deliver a 1-on-1 intervention. By age 5 years, this resulted in better phonological awareness and letter knowledge. There was weak evidence of better expressive, but not receptive, language. (Read the full article)

Unintentional injuries lead to a significant number of children suffering from long-lasting posttraumatic stress symptoms. Therefore, early identification of individuals at risk is crucial to provide preventative interventions. However, currently, no early screener has been evaluated in preschool-aged children.

Good sensitivity (85%) and acceptable specificity (63%) were found for an early screening measure for preschool-aged children after accidental injury. Hence, the 21-item Pediatric Emotional Distress Scale–Early Screener, a reliable and valid early screening instrument, is suggested for use within a stepped-care model. (Read the full article)

Invasive methicillin-resistant Staphylococcus aureus (MRSA) in children is associated with high morbidity and mortality. Although reductions in health care–associated MRSA infection among adults are documented, it is unclear if a similar trend is occurring among children.

Data from population-based surveillance were analyzed to assess changes in invasive MRSA infection incidence over time. This analysis describes the epidemiology and trends of invasive MRSA infections among children in 9 US metropolitan areas and estimates national burden. (Read the full article)

Extremely preterm infants are at high risk of neonatal mortality or morbidities. Existing prediction models focus on mortality, specific morbidities, or composite mortality and morbidity outcomes and ignore differences in outcome severity.

A simple and practical statistical model was developed that can be applied on the first day after NICU admission to predict outcome severity spanning from no morbidity to mortality. The model is highly discriminative (C-statistic = 90%) and internally valid. (Read the full article)

Childhood interstitial lung diseases occur in a variety of clinical contexts and are associated with high morbidity and mortality. Advances in the understanding of disease pathogenesis and use of standardized terminology have facilitated increased case ascertainment.

This study demonstrates that cases of newly described forms of childhood interstitial lung diseases likely occur at all children’s hospitals. With advances in genetic testing and recognition of imaging patterns, a significant portion of cases are identifiable with noninvasive evaluations. (Read the full article)

Pneumonia is the leading cause of death in young children worldwide. Anemia, widely prevalent globally, is not routinely assessed when treating pneumonia. The effect of anemia and high altitude on outcome of pneumonia is not well described.

Anemia at high altitude increases the risk of poor outcome with severe pneumonia. Children with severe pneumonia at high altitude present with more severe hypoxemia and have a longer time to recovery than children at low altitude. (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.

Links between clinically diagnosed sleep problems and adverse behavioral outcomes are well documented. However, in nonclinical populations, causal links between disrupted sleep and the development of behavioral difficulties are far from clear.

Seven-year-old children with nonregular bedtimes had more behavioral difficulties than children who had regular bedtimes. There were clear dose–response relationships, and the effects of not having regular bedtimes appeared to be reversible. (Read the full article)

Higher-hazard, no-benefit research involving children may be approved by local institutional review boards only when the protocol enrolls children with the medical condition under study. The ethics of this distinction have been debated, but parental opinions have not been explored.

We found that parental opinions support federal regulations. We discuss parental motivations for and against research participation and the extent to which enrolling a child in higher-hazard, no-benefit research reflects appropriate surrogate decision-making. (Read the full article)

Gunshot injuries are an important cause of preventable injury and mortality in children, with emergency services often providing the initial care for patients. However, there is little recent population-based research to guide public health, injury prevention, and health policy efforts.

Gunshot injuries are uncommon in children, but cause greater injury severity, need for major surgery, mortality, and costs compared with other injury mechanisms. There is also large variation in the population-adjusted incidence of pediatric gunshot injuries between regions. (Read the full article)

Use of complementary and alternative medicine (CAM) is increasingly common among American youth; however, information on use of CAM among youth with recurrent headache (HA) is limited.

Youth across a range of chronic conditions experience HA. These youth are more likely to use CAM. Use and expenditures for conventional medical care, and increased difficulties in activity and functioning are greater for youth with HA who use CAM. (Read the full article)

Physical activity (PA) levels in preschool children vary considerably between preschools, and are positively associated with the overall quality of the preschool. However, knowledge regarding specific characteristics of the preschool environment hypothesized to promote PA is inconsistent and lacking.

This study tested multiple potential correlates of preschool children’s objectively measured moderate and vigorous PA level during preschool attendance, identifying size of indoor area per child and location of preschool building on the playground as new potentially modifiable correlates.

Transition from pediatric to adult care is often reported to be unsuccessful. Little evidential research has examined the actual proportion of youth in pediatric versus adult care or impact on health status outcomes after transferring from pediatric to adult care.

Our article extends the literature by providing health transition outcome data, something that has been recognized as a critical gap to developing evidence-based programming and health care transition policy. (Read the full article)

Pertussis rates are on the rise in the United States. Infants often require hospitalization for pertussis. Vaccination can change hospitalization patterns for vaccine-preventable diseases. It is unknown if vaccinating adolescents for pertussis (recommended in 2006) might change infant hospitalization utilization.

Universal vaccination policy among adolescents against pertussis appears to have been effective in 3 of the 4 years we examined postvaccination. Further vaccination efforts among adolescents and adults are needed to prevent infantile hospitalization on a more consistent basis. (Read the full article)

Although providing improved survival for infants with very severe cardiorespiratory problems, the use of neonatal extracorporeal membrane oxygenation has high rates of disability in survivors. Mild hypothermia has been shown to limit brain injury in a range of patient groups, including newborns.

Infants who received extracorporeal membrane oxygenation and mild hypothermia did not show an improved neurodevelopmental outcome, and nonsignificant trends in the data suggested a small adverse effect. Use of hypothermia in other potential patient groups should be thoroughly tested. (Read the full article)

School outbreak investigation in Quebec, Canada suggested that adolescents previously vaccinated with 2 doses of measles vaccine beginning at 12 months of age were at greater measles risk than those whose first dose was given at ≥15 months of age.

Greater measles risk among earlier first-of-2-dose vaccine recipients was replicated as a generalized provincial finding during the 2011 epidemic in Quebec, Canada. The mechanism remains unknown, but the findings warrant additional evaluation in the context of measles elimination efforts. (Read the full article)

Unintentional overdose and emergency department visits secondary to nonmedical use of prescription drugs are on the rise with peak age of onset in midadolescence for these risk behaviors. Also, risk behaviors, such as substance use and violence, tend to cluster.

Approximately 1 in 10 adolescents or young adults using the emergency department endorse nonmedical prescription opioid or sedative use in the past year. Rates of current opioid or sedative prescriptions are low among this group. (Read the full article)

As more children with sickle cell disease survive into adulthood, they are increasingly hospitalized in both children’s and general hospitals and managed by different provider specialists. But it is unknown if hospital type and provider specialty affect patient outcomes.

Using a large national administrative dataset, this study revealed that general hospitals were associated with higher rates of intubation and longer lengths of stay compared with children’s hospitals for adolescents and young adults with SCD admitted with acute chest syndrome.

Influenza-associated deaths in children occur every year among children of all ages. Young children and those with high-risk medical conditions are at higher risk of influenza-related complications.

This study describes influenza-associated pediatric deaths over 8 influenza seasons in the United States and compares characteristics of deaths in children with high-risk medical conditions with those in children without high-risk medical conditions. (Read the full article)

Some studies suggest a contribution of environmental exposures such as pesticides to risk of hypospadias, whereas others do not. One of the challenges that has limited current knowledge is the lack of detailed exposure data.

This study examined a more detailed assessment of exposure to pesticides than previous studies. Exposure assignments, whether to groups of chemicals, specific chemicals, or a composite involving a number of chemicals, showed a general lack of association with hypospadias. (Read the full article)

It has previously been shown that exposure to intimate partner violence and/or parental depression or anxiety may increase a child’s risk for specific adverse health outcomes.

By using a large pediatric primary care sample, this study examined associations of child exposure to intimate partner violence and parental psychological distress with developmental milestone attainment by analyzing their combined and separate effects while adjusting for other family factors.

Epidemiologic studies have documented that children’s sleep duration is associated with obesity risk. Experimental studies with adults suggest that short sleep may lead to changes in appetite-regulating hormones and food intake, which could lead to weight gain over time.

This controlled experimental study demonstrates that compared to sleeping less, when children increase sleep, they report decreased caloric intake, have lower fasting leptin levels, and weigh less. Such changes, if maintained, could help prevent excess weight gain over time. (Read the full article)

Children with chronic illnesses tend to be sicker during infections than previously healthy children but are triaged in the same way, even though the validity of triage systems has not yet been evaluated in these chronically sick children.

The performance of the Manchester Triage System was lower for children with a chronic illness than for previously healthy children. Children with cardiovascular illnesses, respiratory illnesses, gastrointestinal illnesses, or other congenital or genetic defects were especially at risk of being undertriaged.

Previous research has shown the following: the mere presence of weapons can increase aggression, dubbed the "weapons effect"; violence in films has increased over time; and violent films can increase aggression.

This study examines a potential source of the "weapons effect": the presence of guns in films. In just 20 years, gun violence in PG-13 films (age 13+) has increased from the level in films rated G/PG to the point where it exceeds the level in R films. (Read the full article)

Peripherally inserted central catheters (PICCs) are essential to deliver life-saving treatment to neonates. Longer PICC dwell times may increase the risk of central line–associated bloodstream infections (CLABSIs) in neonates, but previous studies have yielded inconsistent results, likely due to different study designs, analytic methods, and small sample sizes.

The risk of CLABSIs increases during the 2 weeks after PICC insertion and remains elevated for the catheter duration. These data support daily review of PICC necessity, optimization of catheter maintenance practices, and consideration of novel strategies to prevent CLABSIs. (Read the full article)

Bullying involvement is associated with deleterious psychological, educational, and health effects. However, little is known about relations between bullying involvement and sexual risk-taking behaviors or whether similar patterns hold for heterosexual and gay, lesbian, bisexual, transgendered, or questioning adolescents.

Among adolescents, bullies and bully-victims engaged in more casual sex and sex under the influence than their peers. Controlling for demographic characteristics and other victimization exposures, bully and bully-victim status predicted sexual risk taking but primarily for heterosexual adolescents.
