Pediatric myasthenia encompasses a group of rare and underdiagnosed conditions affecting the neuromuscular junction. Symptoms include fluctuating skeletal muscle weakness, which can progress to respiratory failure if left untreated. The autoimmune form of this condition, in particular, is treatable.

This study describes the incidence, clinical features, diagnostic testing, and treatment trends of pediatric myasthenia in Canada, which have not been previously reported in the literature. (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)

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)

Several studies have been published evaluating the impact of 2011 Accreditation Council for Graduate Medical Education duty hour regulations. Although resident quality of life may be improved, it appears that resident education and patient care may be worse.

This is the first study to evaluate pediatric program director approval of 2011 Accreditation Council for Graduate Medical Education Common Program Requirements and the perceived impact of the regulations on patient care, resident education, and quality of life. (Read the full article)

End-stage kidney disease (ESKD) causes significant morbidity and mortality after solid organ transplantation. Adults commonly develop advanced kidney disease, particularly after liver and intestinal transplantation. Previous pediatric studies have not compared the relative incidence of ESKD by organ type.

This national cohort study shows the highest risk of ESKD among pediatric lung and intestinal transplant recipients, reflecting unique organ-specific causes of kidney injury. Our findings have implications for screening for and treating early kidney disease in transplant recipients. (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)

Obesity and overweight can seriously affect health outcomes. Many obesity prevention interventions have been proposed, but few have been effective. Motivational interviewing in primary care seems promising, but results in BMI control are controversial and require further investigation.

This is the first study to demonstrate the effectiveness of pediatrician-led motivational interviewing for BMI control in overweight children aged 4 to 7 years. Nevertheless, no effect was observed in boys or when the mother’s education level was low. (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)

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)

Over the past 10 years, children’s hospitals increasingly have established pediatric palliative care programs, but little is known about the prevalence of these programs or their geographic distribution, range of services offered, staff composition, or funding.

Among the 162 hospitals that responded to this survey (71.7% response rate), 69% have a pediatric palliative care program, with substantial variation across programs in terms of how they are staffed and funded and what services they provide. (Read the full article)

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

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

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.

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)

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)

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)

Pediatric surgery is performed in a variety of hospital types. General surgeons as well as fellowship-trained pediatric surgeons and surgical subspecialists perform inpatient operative procedures on infants and children. The distribution of procedures between specialists is not well characterized.

This study describes the demographics of pediatric surgery: the hospital type, the surgical procedures, and the quantity of inpatient pediatric surgery in the U.S. today. By implication, the data has much to inform health care about hospital and practitioner workforce. (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. (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)

Fewer clinical trials are performed in children compared with other patient populations. It is unknown how well existing pediatric clinical trials are aligned with the needs of children, both in high-income countries and globally.

There is only moderate correlation between clinical trial activity and pediatric burden of disease, with certain conditions substantially underrepresented in the current research portfolio. Our findings provide a benchmark for prioritizing conditions for study, analyzing gaps, and identifying funding priorities. (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)

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)

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)

Infants with trisomy 13 (T13) or trisomy 18 (T18) are known to have poor survival. Little is known about how very low birth weight (VLBW) impacts survival and morbidities among infants with T13 or T18.

We examined the risks of mortality and neonatal morbidities for VLBW infants with T13 or T18 compared with VLBW infants with trisomy 21 and VLBW infants without birth defects in a 16-year cohort from the Neonatal Research Network. (Read the full article)

Recommended management of febrile neonates (≤28 days) includes blood, urine, and cerebrospinal fluid cultures with hospital admission for antibiotic therapy. No study has reported adherence to standard recommendations in the management of febrile neonates in US pediatric emergency departments.

There is wide variation in adherence to recommended management of febrile neonates. High rates of serious infections in admitted patients but low return rates for missed infections in discharged patients suggest additional studies needed to understand variation from current recommendations.

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. (Read the full article)

Fetal growth restriction, particularly in preterm children, is associated with delayed development and poor growth. Knowledge about the consequences of fetal growth restriction if classified by symmetry is lacking, especially in preterm children.

In preterm children, symmetric and asymmetric growth restriction at birth results in poorer growth later in life. Both groups are at considerable risk of developmental delay because their long-term development is independent of their head circumference at birth. (Read the full article)

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

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

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)

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)

Prenatal lipid-based nutrient supplementation has been demonstrated to increase birth length. However, the impact of this intervention on infant growth and morbidity is unknown.

Infants from mothers who were given prenatal lipid-based nutrient supplements showed decelerated linear growth. The gain in length at birth related to prenatal lipid-based nutrient supplementation was not sustained during infancy. (Read the full article)

Little is known about the epidemiology and pathogenicity of Clostridium difficile infection among children, particularly those aged ≤3 years in whom colonization is common and pathogenicity uncertain.

Young children, 1 to 3 years of age, had the highest Clostridium difficile infection incidence. Considering that clinical presentation, outcomes, and disease severity were similar across age groups, C difficile infection in the youngest age group likely represents true disease and not asymptomatic colonization.

Recent studies have shown that participating in the Supplemental Nutrition Assistance Program (SNAP) is associated with improved household food security. With the exception of 1 descriptive analysis, studies have not examined how SNAP affects children’s food security.

This article estimates the association between SNAP and children’s food security using the largest, most rigorous national study of food security to date. Given current proposals to reduce program size, this study underscores SNAP’s importance in affecting children’s well-being. (Read the full article)

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

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

Kidney transplantation is the optimal treatment of children with end-stage renal disease. The field of pediatric kidney transplantation has changed over time with regard to immunosuppression, surgical technique, organ allocation policy, and rates of living donor transplantation.

Outcomes after pediatric kidney transplantation in the United States have improved over time, independent of changes in recipient, donor, and transplant characteristics. These improvements were most dramatic within the first posttransplant year and among the most highly sensitized patients. (Read the full article)

We previously reported that parents of children enrolled in genomic research made more restrictive data sharing (DS) decisions than adults. The ethics of pediatric DS have been discussed, but reasons for differences in decision-making have not been explored.

We present an empirically based discussion of attitudes toward and preferences for DS obtained from structured interviews of adult patients and parents of pediatric patients enrolled in genomic research studies. Parents expressed more concern about future risks than adult participants. (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)

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)

Initial studies in children and young adults have identified higher levels of anxiety and lower quality of life scores in patients with implantable cardioverter–defibrillators. Few studies are available looking at the same questions in young patients with pacemakers.

Anxiety is highly prevalent in young patients with ICDs, but the higher rates can be attributed to medical disease severity and age at implantation rather than type of device. Patients with pacemakers have depression and anxiety but at lower rates. (Read the full article)

Ceftriaxone at therapeutic doses can lead to renal stone formation.

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

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)

Many studies have demonstrated that the built environment is related to both collision risk and walking to school. However, little research examines the influence of the built environment on the relationship between walking to school and pedestrian collision risk.

Increased walking was not associated with increased pedestrian collision once the effects of the built environment and socioeconomic status were modeled. Safety was related primarily to the built environment and specifically features related to road crossing. (Read the full article)
