Hypovitaminosis D is common among children. Although there is prolific biochemical literature linking vitamin D to enteric immunologic function, there is a paucity of prospective data exploring the role of supplementation in prevention of diarrheal illnesses.

In a high-risk population, quarterly supplementation with 100 000 IU of vitamin D₃ did not reduce the risk for first or recurrent diarrheal illnesses in a population of children aged 1 to 29 months in a low-income inner city setting. (Read the full article)

Participating in a trial may affect processes of care by participating physicians; however, no study has assessed whether it affects processes of care for nonenrolled patients.

Participation in a trial may affect processes of care for nonenrolled patients, even when care providers participating in or familiar with the trial protocol are unaware that data on nonenrolled patients are being collected for a study. (Read the full article)

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)

Some infants presenting with bronchiolitis are later diagnosed with asthma. Corticosteroid treatment of all infants with bronchiolitis is not clearly efficacious.

We used infant eczema or asthma history in a first-degree relative to select patients with bronchiolitis for dexamethasone or placebo blinded treatment. Dexamethasone treatment of 5 days led to significantly earlier readiness for discharge from infirmary treatment. (Read the full article)

Traumatic brain injury (TBI) in children causes significant morbidity and mortality. Parental and coach awareness about brain injury due to sports has recently increased. Since 2001, pediatric emergency departments have seen a significant increase in sports-related TBI.

Pediatric, sports-related TBIs cared for in the emergency department and admitted to the hospital have both increased, resulting in no change in the percentage being admitted. However, patients admitted have had a significant reduction in injury severity. (Read the full article)

Apnea is a life-threatening complication of bronchiolitis and has been associated with younger age, prematurity, and a parental report of apnea. Apnea is classically attributed to the respiratory syncytial virus, but little is known about the role of other viruses.

Among hospitalized children, low or high respiratory rates or low oxygen saturation on presentation were associated with subsequent apnea in the hospital. Several bronchiolitis pathogens were associated with apnea, with similar apnea risk across the major viral pathogens. (Read the full article)

Palivizumab prophylaxis prevents respiratory syncytial virus lower respiratory tract infection. An association between respiratory syncytial virus infection and subsequent recurrent wheezing has been suggested by many studies. Only a few studies conducted from Europe and North America have addressed this causal association.

In a prospective, multicenter, case-control study of 440 children with high follow-up rate of 98.4%, palivizumab prophylaxis administered to preterm Japanese infants (33–35 weeks’ gestational age) in their first respiratory season reduced the incidence of subsequent recurrent wheezing up to 3 years.

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)

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)

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)

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)

Recent guidelines for the management of childhood pneumonia recommend narrow-spectrum antimicrobial agents (eg, ampicillin) for most children; however, few studies have directly compared the effectiveness of narrow-spectrum agents to the broader spectrum third-generation cephalosporins commonly used among children hospitalized with pneumonia.

By using data from 43 children’s hospitals in the United States, we demonstrate equivalent outcomes and costs for children hospitalized with pneumonia and treated empirically with either narrow- (ampicillin/penicillin) or broad-spectrum (ceftriaxone/cefotaxime) antimicrobial therapy.

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)

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)

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)

Few data on treating children hospitalized for influenza with neuraminidase inhibitors are available, contributing to uncertainty regarding the benefits of treatment.

This study of nearly 800 critically ill children suggests that treatment with neuraminidase inhibitors improves survival from influenza. This message needs additional emphasis, given that in the past 2 seasons over one-third of cases did not receive antiviral treatment. (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)

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)

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)

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)

Infant sleep and crying problems are common and associated with postnatal depression. No programs aiming to prevent all 3 issues have been rigorously evaluated.

A prevention program targeting these issues improves caregiver mental health, behaviors, and cognitions around infant sleep. Implementation at a population level may be best restricted to infants who are frequent feeders because they experience fewer crying and daytime sleep problems. (Read the full article)

An algorithm for neonatal early-onset sepsis risk based on Centers for Disease Control and Prevention 2002 guidelines for prevention of perinatal Group B Streptococcus disease results in the evaluation of ~12–15% of well-appearing term and late preterm infants.

A revised algorithm based on the Centers for Disease Control and Prevention 2010 guidelines eliminated 25% of all early-onset sepsis evaluations and resulted in significant cost savings, without short-term evidence of harm. (Read the full article)

Firearm injuries are the second leading cause of death among American children. Previous estimates of nonfatal injuries have relied on small samples of emergency department visits and do not allow a detailed understanding of these injuries among children and adolescents.

In 2009, there were 7391 hospitalizations for firearm-related injuries in US children and adolescents; 89% of hospitalizations occurred in males. Hospitalization rates were highest for 15- to 19-year-olds and for black males. Deaths in the hospital occurred in 6.1% of children and adolescents. (Read the full article)

In preterm infants receiving supplemental oxygen, manual control of the inspired oxygen fraction is often difficult and time consuming, which may increase the risk of complications. We developed a system for automatic oxygen control and proved its efficacy in the past.

A multicenter study adds evidence for the proposed automatic oxygen control system to significantly improve oxygen administration to preterm infants receiving mechanical ventilation or nasal continuous positive airway pressure while reducing workload compared with routine manual oxygen control.

Sibship size has been negatively associated with children’s language, cognitive, and academic outcomes. This phenomenon is often explained in terms of resource dilution, wherein more children in the home is associated with fewer parental resources allocated to each child.

The current study identifies a moderator of this relationship. Specifically, if children’s next-in-age older siblings exhibit high levels of cognitive sensitivity then sibship size is not significantly related to children’s vocabulary. (Read the full article)

Children who have experienced early psychosocial deprivation are at high risk of persistent, socially indiscriminate behaviors. These behaviors may decline slowly with high-quality caregiving but generally are associated with ongoing impairment.

This study suggests that placement in foster care reduces indiscriminate behaviors to an intermediate level between those in institutional care and community control subjects. It also demonstrates the importance of disorganized early attachment in predicting later indiscriminate behaviors. (Read the full article)

Research indicates that bullying, a type of peer victimization, is related to worse mental and physical health. Most previous studies have been cross-sectional and have not examined effects of bullying over time.

This analysis examined longitudinal effects of bullying on mental and physical health from middle school to high school. Experiencing chronic bullying, especially in both the past and present, was associated with worse psychological and physical health. (Read the full article)

Viral wheezing is common in preschool-aged children. The efficacy of inhaled steroids in preventing viral wheezing is debated. Despite this debate, nebulized beclomethasone is widely prescribed (particularly in a few countries) to children with upper respiratory tract infections.

Findings from this study confirm that inhaled steroids are not effective in preventing viral wheezing. Moreover, no differences were found in the persistence of symptoms (eg, runny nose, sore throat) or in the parental perception of asthma-like symptom severity. (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)

Pulse oximeter is better than skin color assessment in the initial minutes of life. After sensor application, a delay occurs in the display of reliable saturation and heart rate. An appropriate method of sensor placement can minimize the delay.

Attaching sensor first to oximeter and then to neonate picked up signal faster than attaching it to the neonate first and then to the equipment. However, the time from birth to display of reliable signal was similar between the methods. (Read the full article)

Many parenting Web sites encourage use of infant "sleep machines" to play ambient noise while infants sleep. Noise recommendations for hospital nurseries suggest a limit of 50 A-weighted dB, whereas occupational standards limit exposure times for noise >85 A-weighted dB.

We measured the maximum sound level outputs of infant sleep machines and found that several devices are capable of producing levels that may be damaging to infant hearing and may be detrimental to auditory development. (Read the full article)

Maintaining high levels of measles-mumps-rubella immunization is an important public health priority that has been threatened by discredited claims about the safety of the vaccine. Relatively little is known about what messages are effective in overcoming parental reluctance to vaccinate.

Pro-vaccine messages do not always work as intended. The effectiveness of those messages may vary depending on existing parental attitudes toward vaccines. For some parents, they may actually increase misperceptions or reduce vaccination intention. (Read the full article)

The first evaluation of the economic impact of all vaccines in the routine US childhood immunization schedule assessed the 2001 schedule (excluding pneumococcal conjugate and influenza vaccines) and documented substantial cost savings over the lifetimes of the cohort of children born in 2001.

This report updates our previous evaluation, and estimates the costs and benefits of vaccinating the cohort of children born in 2009. We include vaccines routinely recommended for children in 2009. (Read the full article)

Diarrhea still remains as a significant cause of morbidity and mortality. Intervention to reduce this risk are needed. Evidence on the effect of Lactobacillus reuteri DSM 17938 to prevent diarrhea in children is scarce.

In healthy children attending day care centers, daily administration of L reuteri DSM 17938 had a significant effect in reducing episodes and duration of diarrhea and respiratory tract infections, with consequent cost saving for the community. (Read the full article)

Adolescents and young adults consume a significant amount of health care resources in our current medical system. With the Patient Protection and Affordable Care Act, a much larger number of previously uninsured young adults (aged ≥19) will be covered.

The Military Health System provides valuable information about the health utilization patterns of adolescents and young adults (aged 12–22) with universal insurance and excellent access to care. This information may help us understand the impact of new health care legislation. (Read the full article)

The pediatric mental health burden is substantial, with >4 million children meeting criteria for a mental health disorder. Mental health is a key priority for national pediatric inpatient quality measures, but little is known about admitted patients and their diagnoses.

Nationally, nearly 10% of hospitalizations in children >3 years are for primary mental health diagnoses. The most common and costly are depression, bipolar disorder, and psychosis. Fewer free-standing children’s hospitalizations (3%) were for mental health admissions, although diagnostic distributions were similar. (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)

Integrated or collaborative care intervention models have revealed gains in provider care processes and outcomes in adult, child, and adolescent populations with mental health disorders. However optimistic, conclusions are not definitive due to methodologic limitations and a dearth of studies.

This randomized trial provides further evidence for the efficacy of an on-site intervention (Doctor Office Collaborative Care) coordinated by care managers for children's behavior problems. The findings provide support for integrated behavioral health care using novel provider and caregiver outcomes. (Read the full article)

Early preventive dental care is cost-effective and can reduce subsequent restorative or emergency visits. Little is known about the factors distinguishing families who receive dental care in early childhood and those who do not.

Our results suggest that among healthy children seen by primary care providers, those most in need of dental care are least likely to receive it. This highlights the importance of promoting early preventive dental care in the primary care setting. (Read the full article)

There is wide variation in pediatric subspecialty supply in the United States. The impact of this variation in supply on utilization and child and family disease burden is not known.

Among children with special health care needs, living in a county with lower subspecialty supply was associated with lower perceived need for subspecialty care, lower subspecialty utilization, and no meaningful differences in examined measures of child and family disease burden. (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)

Although a number of randomized controlled trials of erythropoietin administration to preterm infants have been performed, few studies have reported 2-year or longer neurodevelopmental outcomes, and no studies have evaluated neurodevelopmental outcomes of infants randomized to receive Darbepoetin.

This is the first prospectively designed study to evaluate the neurocognitive outcomes of preterm infants randomized to receive Darbepoetin or erythropoietin compared with placebo. Infants in the ESA groups had significantly higher cognitive scores compared with the placebo group. (Read the full article)

Reasons for childhood immunization delay include parental intent and barriers such as transportation. To date there has been 1 study of the association of delayed vaccination and seizures, which found measles-mumps-rubella and measles-mumps-rubella-varicella vaccines are both associated with a higher rate of seizures if received after 15 months of age.

Our study found no association between the timing of vaccination and occurrence of seizures in the first year of life. By using different methods, our results support the observation that delaying vaccination with measles-containing vaccines past 15 months of age increases the incidence of postvaccination seizures. (Read the full article)

Since the introduction of rotavirus vaccines, diarrhea-associated health care utilization among US children has decreased substantially. Moreover, indirect benefits from rotavirus vaccination have been observed in unvaccinated children and in adults.

With increasing rotavirus vaccine coverage during 2009–2011, we observed continued reductions in diarrhea-associated health care utilization and cost. Both rotavirus vaccines conferred high protection against rotavirus hospitalizations; pentavalent rotavirus vaccine provided durable protection through the fourth year of life.

Pneumonia is a leading cause of hospitalization among children, and readmissions after discharge are common.

Eight percent of children experience a readmission within 30 days after hospital discharge for pneumonia. Readmissions are most common among young children and those with chronic medical conditions, and are associated with substantial costs. (Read the full article)

Previous research has demonstrated that family presence alongside hospitalized patients is associated with improvements in physiologic responses, reductions in anxiety, and expedited recovery. Recently, videoconferencing has been increasingly used for virtual visits to pediatric patients and their parents during hospitalization.

Our study demonstrates that in some cases, the use of videoconferencing by children and their parents for virtual visits is associated with greater reductions in stress during hospitalization compared with children and parents who do not use videoconferencing. (Read the full article)

The Centers for Disease Control and Prevention recommends that health departments in all 50 states deliver AFIX (Assessment, Feedback, Incentives, and eXchange) consultations to 25% of federally funded vaccine providers each year. AFIX effectively raises vaccination coverage among young children.

AFIX consultations achieved short-term gains in coverage for 11- to 12-year-olds for vaccines in the adolescent platform. No gains occurred for older adolescents or over the long term. Consultations were equally effective when delivered in-person or by webinar. (Read the full article)

Children with autism sleep poorly compared with their peers. Sensory integration, including use of weighted blankets, is proposed as a means to reduce arousal and stress. There is, however, no evidence that weighted blankets can improve sleep for these children.

This is the first robust study to evaluate the impact of weighted blankets and show that they do not improve sleep parameters in children with autism spectrum disorder. (Read the full article)

Mothers of children with neurodevelopmental disabilities often experience poor health, high stress, anxiety, and depression. Highly stressed parents are less effective in their parenting roles, risking their children's developmental progress.

Evidence-based interventions in mindfulness and positive psychology significantly reduce distress in mothers of children with disabilities. Well-trained peer-mentors are effective interventionists. Adult-oriented services are needed for these mothers to improve their mental health and sustain their caregiving over the long-term. (Read the full article)
