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)

Although most US mothers initiate breastfeeding, half fail to achieve their breastfeeding intentions. In cross-sectional and retrospective surveys, early breastfeeding difficulties are often cited as reasons for stopping breastfeeding earlier than intended.

We characterized 4179 breastfeeding concerns/problems as reported by primiparas interviewed prospectively. Concerns were highly prevalent and associated with up to ninefold greater risk of stopping breastfeeding earlier than intended. Concerns at 3 to 7 days posed the greatest risk.

More than 70% of all preterm deliveries are late-preterm (34–36 weeks of gestation). Compared with those born at term, those born late-preterm have higher risk for medical and neurodevelopmental disabilities and suffer more often from mental and behavioral problems.

Late-preterm birth is associated with considerable lifetime socioeconomic disadvantages across the adult years. These disadvantages are not explained by childhood parental socioeconomic position. (Read the full article)

Prosmoking messages, delivered through marketing and the media, can reach very young children and influence attitudes and behaviors around smoking.

Marketing of tobacco and cigarette brands has successfully reached young children in low- and middle-income countries. More effective measures are needed to restrict the reach of tobacco marketing. (Read the full article)

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)

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)

Lower risk of early celiac disease (CD) has been observed with breastfeeding and low dose of gluten at introduction. Gluten introduction before 4 or after 6 months has been associated with increased risk. For CD diagnosed after 2 years, the association is unclear.

Gluten introduction delayed to >6 months as well as breastfeeding >12 months was associated with a modest increase in CD in this first population-based birth cohort study, and gluten introduction under continued breastfeeding was not protective. (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)

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)

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)

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)

Cooling infants with hypoxic-ischemic encephalopathy shortly after birth improves survival and neurodevelopmental outcome. The optimal way to cool infants during transfer to regional NICUs is unclear.

Data from a regional neonatal transfer team, using first passive and subsequently active cooling for these infants, suggest that active cooling results in improved thermal control and a reduction in stabilization time. (Read the full article)

Several studies have shown that behavioral problems can be associated with defecation and voiding disorders, although few studies have looked directly at a link between a diagnosis of attention-deficit/hyperactivity disorder (ADHD) and constipation or fecal incontinence.

We identified an increased risk for both constipation and fecal incontinence in children with ADHD. In patients with concomitant ADHD and defecation disorders, more aggressive medical and behavioral treatment of the constipation or fecal incontinence may be warranted. (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)

Sharing human milk between those with an abundant supply and those seeking milk for their child may be growing in popularity, facilitated by Web sites recently established to link providers and recipients.

This study documents the potential for human milk shared via the Internet to cause infectious disease by estimating the extent of microbial contamination among samples purchased via a leading Internet Web site. (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.

Several studies have documented earlier onset of pubertal maturation in girls, with several potential factors attributed to the earlier onset.

This study demonstrates earlier maturation in white non-Hispanic girls, with greater BMI linked as a major factor. The entire distribution of pubertal timing has shifted to a younger age, suggesting redefinition of ages for both early and late maturation. (Read the full article)

The World Health Organization estimates that ~700 million children breathe tobacco smoke polluted air, particularly at home. Educational strategies either directly or indirectly targeting household decision-makers through other family members are effective in reducing children's exposure in private homes.

Intensive intervention was effective in decreasing children’s personal exposure to secondhand smoke (SHS), educating mothers about SHS, and promoting smoking restrictions at home. However, superiority over minimal intervention to decrease children’s personal exposure to SHS was not statistically significant. (Read the full article)

Preterm infants are born with low serum levels and low body stores of tocopherol. Serum levels ≥0.5 mg/dL are required for protection against lipid peroxidation. Previous studies have shown good intestinal absorption of vitamin E given intragastrically to preterm infants.

Serum α-tocopherol increases after a single 50-IU/kg dose of vitamin E as dl-α-tocopheryl acetate given intragastrically to very preterm infants soon after birth; however, 30% of infants still have serum α-tocopherol level <0.5 mg/dL 24 hours after dosing. (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)

In 2007, manufacturers voluntarily withdrew over-the-counter (OTC) infant cough and cold medications (CCMs) from the US market. A year later, manufacturers announced OTC CCM labeling would be revised to warn against OTC CCM use by children aged <4 years.

Among children aged <2 and 2 to 3 years, emergency department visits for CCM adverse events declined nationally after the withdrawal and labeling revision announcement relative to all adverse drug event visits. Unsupervised ingestions caused most CCM adverse events after each intervention. (Read the full article)

Young age at first sexual intercourse (FSI) is related to risk-taking behaviors and negative outcomes. Previous studies using a cohort or cross-sectional design have concluded that younger age at menarche (AAM) is related to younger age at FSI.

This large birth cohort study is the first to address the temporal relationship between AAM and FSI. We found that younger AAM does not confer higher risk of early FSI, whether in terms of calendar age or time since menarche. (Read the full article)

Stable health insurance coverage facilitates access to health care. Despite expanded coverage options for children, parents report barriers to accessing insurance programs for their children, including uncertainty about a child’s coverage status and eligibility.

Electronic health records can be used as an emerging data source for conducting health insurance surveillance to track trends in patients’ insurance coverage status, and to identify patients who may benefit from outreach and support to obtain and maintain coverage. (Read the full article)

Late-onset sepsis is a frequent complication of prematurity, contributing to morbidity and mortality. Although evidence is accumulating that administration of probiotics to very preterm infants reduces necrotizing enterocolitis (NEC) and all-cause mortality, the effect on late-onset sepsis is less clear.

The probiotic combination Bifidobacterium infantis, Streptococcus thermophilus, and Bifidobacterium lactis reduced NEC in very preterm infants, but not mortality or late-onset sepsis. Probiotics may be of greatest global value in neonatal settings with high rates of NEC. (Read the full article)

Although community engagement is considered an important professional role of physicians, there has been declining involvement of pediatricians in community child health activities. Whether enhanced training is associated with increased involvement is unclear.

This study reveals a continued decline in pediatricians’ involvement in community child health activities and is the first national study to identify a link between formal training and pediatricians’ community involvement. (Read the full article)

Several studies have suggested that very low birth weight young adults have increased risks of physical and health problems, educational underachievement, and poorer social functioning than their peers, but there are limited population-based and longitudinal data.

Former VLBW young adults in this national cohort scored as well as term controls on many measures of health and social functioning, including quality-of-life scores, with some differences largely confined to those with disability at age 7 to 8 years. (Read the full article)

Breast milk is protective against many conditions, but its role in allergy has not been established. Infant-feeding recommendations support exclusive breastfeeding for 26 weeks, whereas allergy prevention recommendations advise exclusive breastfeeding for 4 to 6 months with continued breastfeeding thereafter.

Evidence that continued breastfeeding while solids are introduced into the diet and delaying the introduction of solids until at least 17 weeks of age are associated with fewer food allergies. (Read the full article)

Socioeconomic status is known to influence health and health care utilization, but few studies have explored the relationship between community-level income and inpatient resource utilization for children.

In a large sample of pediatric hospitalizations, lower community-level household income is associated with higher inpatient costs of care for common conditions. These findings highlight the need to consider socioeconomic status in health care system design and reimbursement. (Read the full article)

Medication errors occur frequently among pediatric patients, particularly those treated in rural emergency departments (EDs). Although telemedicine has been proposed as a potential solution, there are few data supporting its clinical effectiveness and its effect on medication errors.

The use of telemedicine to provide pediatric critical care consultations to rural EDs is associated with less frequent physician-related ED medication errors among seriously ill and injured children. Therefore, this model of care may improve patient safety in rural hospital EDs. (Read the full article)

One study examined the incidence of obesity among low-income children aged <5 years who participated in federally funded child health and nutrition programs during 1985–1990. The study examined the variations by baseline age but not by gender or race/ethnicity.

This study provides most recent data on incidence and reversing of obesity and variations across gender, baseline age, and racial/ethnic subgroups among young low-income children. We conducted multivariable analyses to examine the relative risk of obesity in population subgroups. (Read the full article)

Parents influence their child’s overweight development through lifestyle-related parenting practices. Although broader parenting dimensions may also affect children’s BMI, reverse causality is possible and there have been calls to examine the possible impacts of fathers.

More consistent parenting prospectively predicted lower child BMI with effects equally strong for fathers and mothers. There was little evidence of child BMI influencing parenting. Improved child BMI could be among the benefits of promoting parenting consistency of both parents. (Read the full article)

Increasing numbers of hospitals are instituting 24/7 in-hospital pediatric intensivist coverage. Data regarding patient outcomes are mixed and the impact on housestaff education remains unknown.

This study quantifies the perceived impact of in-hospital attending coverage on pediatric resident and critical care fellow education and also investigates the growing concern that increasing supervision may contribute to housestaff being less well prepared for independent clinical practice.

Youth are frequent consumers of movies that contain high levels of violence, and violent content in films, especially those rated PG-13, has been increasing over time.

Content analyses seldom examine how violence is portrayed with other health risk behaviors, such smoking, drinking, and sex. This study presents an innovative way to characterize on-screen violent content and demonstrates the extent to which risk behaviors co-occur within films. (Read the full article)

Broad-spectrum antibiotics are frequently used to empirically treat children hospitalized with community-acquired pneumonia despite recent national recommendations to use narrow-spectrum antibiotics.

Narrow-spectrum antibiotics are similar to broad-spectrum antibiotics for the treatment of children hospitalized with community-acquired pneumonia in terms of clinical outcomes and resource utilization. This study provides scientific evidence to support national consensus guidelines. (Read the full article)

Individuals with autism spectrum disorders have a higher comorbidity burden than the general pediatric population, including higher rates of seizures, psychiatric illness, and gastrointestinal disorders.

Comorbidities do not occur evenly. Our clustering analysis reveals subgroups characterized by seizure, psychiatric disorders, and complex multisystem disorders including auditory and gastrointestinal disorders. Correlations between seizure, psychiatric disorders, and gastrointestinal disorders are validated on a sample from a second hospital. (Read the full article)

Hypertonic saline (3% and 5%), has been shown to improve clinical severity scores and reduce inpatient length of stay, and was associated with a trend toward lower admission rate in acute bronchiolitis.

We are not aware of any previous data using 7% hypertonic saline in bronchiolitis. Our results suggest that 7% saline does not lower clinical severity of illness, admission rate, or length of stay, when compared with normal saline. (Read the full article)

Better postnatal growth, especially head growth, associates with better cognitive development in preterm infants. Suboptimal postnatal growth is more common in infants with poor antenatal growth than in infants with normal growth.

Good weight gain and head circumference growth until 2 years was associated with better 5-year cognitive outcome in non–small for gestational age infants. Good head circumference growth around term age benefits the cognitive outcome of small for gestational age infants. (Read the full article)

A serum 25-hydroxyvitamin D (25(OH)D) concentration of 20 ng/mL meets the requirements of at least 97.5% of the population older than 1 year. A recommended dietary intake to achieve this serum 25(OH)D concentration has not been established during infancy.

Daily maternal (during pregnancy) and then infant vitamin supplementation with 1000/400 IU or 2000/800 IU increases the proportion of infants with 25(OH)D ≥20 ng/mL during infancy with the higher dose sustaining this increase for longer. (Read the full article)

Although immunoglobulin replacement is recognized as effective in children with primary immunodeficiency, pneumococcal infection may occur. There is no available prospective clinical study evaluating levels of protective serospecific antibodies in patients and products.

Protective (0.2 µg/mL) antibody levels for the most frequent pneumococcal serotypes were measured in children treated for primary immunodeficiencies. A linear relationship was demonstrated between peak and trough levels of serospecific antipneumococcal antibodies in patients and infused immunoglobulins. (Read the full article)

Payment arrangements that blend global budgets with pay-for-performance are proliferating. However, little is known about how these contracts affect pediatric health care quality and spending for children with and without special health care needs receiving care from large provider organizations.

A prototypical global budget contract significantly improved preventive care quality measures tied to pay-for-performance, especially for children with special health care needs. It did not alter trends for spending or for quality measures that were not tied to pay-for-performance. (Read the full article)

Currently, the false-positive rate of appendicitis in children is ≤5%. Abdominal imaging and blood tests (particularly leukocytosis) help minimize the negative appendectomy rate, but appendicitis is not always associated with an elevated white blood cell count.

Reducing the threshold of leukocytosis as a criterion for appendicitis to 8000 to 9000 white blood cells per µL improves specificity (negative appendectomy: <1%) while only marginally decreasing sensitivity. (Read the full article)

Preterm infants dependent on parenteral nutrition are vulnerable to deficits in early postnatal nutritional intake. This coincides with a period of suboptimal head growth. Observational studies indicate that poor nutritional intake is associated with suboptimal head growth and neurodevelopmental outcome.

This study provides randomized controlled trial evidence that head growth failure in the first 4 weeks of life can be ameliorated with early nutritional intervention. Early macronutrient intake can be enhanced by optimizing a standardized, concentrated neonatal parenteral nutrition regimen. (Read the full article)

Cranial ultrasound is routinely used in identifying cerebral abnormalities in premature infants. Grade III and IV intraventricular hemorrhages, cystic periventricular leukomalacia, and late ventriculomegaly are all known predictors of adverse neurodevelopmental sequelae in these infants.

We reviewed neurodevelopmental outcomes among 2414 extreme preterm infants. Infants with grades I and II intraventricular hemorrhage had increased rates of neurosensory impairment, developmental delay, cerebral palsy, and deafness at 2 to 3 years’ corrected age. (Read the full article)

Systematic health disparities in adults with systemic lupus erythematosus are well documented and are likely driven by biologic as well as modifiable factors. Sociodemographic factors and health care delivery characteristics have been associated with poor outcomes.

In hospitalized children with systemic lupus erythematosus, race and ethnicity were associated with increased risk for ICU admissions, end-stage renal disease, and death. Identification of sociodemographic factors associated with outcomes is important to address the needs of these vulnerable patients. (Read the full article)

Due to reports of unintentional overdoses, in 2011 the US Food and Drug Administration finalized voluntary recommendations for dosing devices included with over-the-counter (OTC) liquid medications. The Consumer Healthcare Products Association previously endorsed similar recommendations for devices and dosing directions.

This study assessed dosing directions and devices for national brand name OTC liquid medications, available after a voluntary FDA guidance, and found high levels of adherence to most recommendations. Further improvement efforts should prioritize recommendations directly addressing potential dosing errors. (Read the full article)

Cognitive rest is recommended for the management of sport-related concussions. There are limited data to support this recommendation.

This study adds empirical data supporting the recommendation for cognitive rest after a sport-related concussion. (Read the full article)

Self-medication with over-the-counter (OTC) analgesics, particularly paracetamol (PCM), among children is widespread and increasing. Parents often administer the medicine. The health care system has little knowledge or possibility to regulate OTC medication, and use of PCM for children may be partly unjustified.

Maternal frequent self-medication with OTC analgesics is associated with frequent use of OTC analgesics, particularly PCM, among 6- to 11-year-old schoolchildren, even when the child’s frequency of pain is accounted for. (Read the full article)

Infant postexposure prophylaxis prevents perinatal hepatitis B (HepB) virus transmission and mortality and morbidity caused by chronic HepB virus infection. The US Perinatal Hepatitis B Prevention Program (PHBPP) identifies and manages infants born to HepB surface antigen–positive women.

It presents the first estimates of the long-term costs and outcomes of postexposure prophylaxis with the PHBPP. It analyzes the effects of the PHBPP, and alternative immunization scenarios, on health and economic outcomes for the 2009 US birth cohort. (Read the full article)
