Reductions in infant mortality in the 20th century have not continued. Racial and socioeconomic inequalities in both infant mortality and sudden infant death syndrome (SIDS) persist. Rates of infant mortality in English-speaking countries are higher than the Organisation for Economic Co-operation and Development average.

At least 16.4% of SIDS and 3.4% of infant deaths not classified as SIDS are attributable to maternal alcohol use. Maternal alcohol-use disorder increases the risk of infant mortality through direct effects on the fetus and indirectly through environmental risk factors. (Read the full article)

Skin and soft tissue infections (SSTIs) are a common pediatric condition often requiring inpatient management. Several studies describe recent increases in hospitalizations due to SSTIs.

In addition to rising hospitalizations, analysis of pediatric SSTI resource utilization trends revealed a twofold increase in incisions and drainages over a 13-year period. A growing number of incisions and drainages were performed in younger children. (Read the full article)

Guidelines encourage pediatric health care providers to aid in identifying women with postpartum depression but not postpartum anxiety, yet the major life event of childbirth can be anxiety provoking for many women.

During the postpartum hospital stay, anxiety was far more common than depression among breastfeeding women. Anxiety remained more common for the 6 months after childbirth, and was associated with increased health care use and reduced breastfeeding duration, particularly among primiparous women.

In Mexico, substantial declines in childhood diarrhea deaths have been documented since the introduction of the rotavirus vaccine in 2007. However, there is concern of lower vaccine effectiveness in less developed regions of Mexico with higher diarrhea-related mortality.

We documented significant and comparable declines across all 3 regions of Mexico with different levels of development, indicating equitable vaccine distribution to children with varying risk of mortality and reaffirming the beneficial effects of rotavirus vaccination against fatal diarrheal disease.

Attention-deficit/hyperactivity disorder (ADHD) has been viewed as a neurodevelopmental disorder, adversely affecting behavior and school performance, with studies suggesting increased risk for poor adult outcomes. However, no prospective studies have examined long-term outcomes of childhood ADHD in an epidemiologic sample.

Our epidemiologic study indicates that adults with childhood ADHD are at increased risk for death from suicide. ADHD persists into adulthood in 29.3% of childhood ADHD cases, and 56.9% have ≥1 psychiatric disorder other than ADHD. (Read the full article)

The triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) estimates atherogenic small, dense low-density lipoprotein cholesterol and predicts arterial stiffness and hard cardiovascular events in adults. Whether TG/HDL-C predicts intermediate noninvasive end points (arterial stiffness) in youth is not known.

This study is the first to document stiffer vessels in youth with higher cardiovascular risk factor–adjusted TG/HDL-C, with the effect especially strong in obese subjects. Evaluating TG/HDL-C may be helpful in identifying young subjects at risk for obesity-related atherosclerosis. (Read the full article)

While obesity-promoting eating, sedentary and physical activity behaviors, and increased prevalence of adiposity are evident from early life, few high-quality studies have evaluated interventions that seek to influence the development of these behaviors in very early childhood.

This study highlights the receptivity of first-time parents to interventions focused on their new infant’s eating and active play and provides evidence of effectiveness on some obesity-promoting behaviors in very early childhood. (Read the full article)

Although it is known that relatively minor abusive injuries sometimes precede more severe physical abuse, the prevalence of these previous injuries in infants evaluated for abuse was not known.

A history of bruising or oral injury in a precruising infant evaluated for abuse should heighten the level of suspicion because these injuries are common in abused infants and rare in infants found not to be abused. (Read the full article)

Although the metabolic syndrome is associated with obesity, not all obese children have insulin resistance and metabolic syndrome, and nonobese children may develop these abnormalities. Associated factors have not been well described.

There was a 6.6% prevalence of nonobese children who were insulin-resistant, associated with a family history of hypertension. There was a 21.3% prevalence of obese who were not insulin-resistant, associated with a low waist circumference. (Read the full article)

Although amphibians are known Salmonella carriers, aquatic African dwarf frogs are specifically marketed toward children, who are especially vulnerable to Salmonella infections. Both direct animal contact and indirect contact with animal habitats can lead to human Salmonella infections.

This is the first reported outbreak of human Salmonella infections associated with African dwarf frogs, particularly among young children. Parents should be aware of the risk of Salmonella infections from both direct and indirect animal contact. Pediatricians should regularly inquire about animal contact and advise families about risks.

Expectations are high that electronic health record–based clinical decision support and performance feedback will improve adherence to guidelines by delivering relevant and actionable information to clinicians. Few studies have evaluated these assertions or examined the combined effects of decision support and feedback.

Clinical decision support customized to a patient’s history and presentation and performance feedback are both effective for improving adherence to guidelines for otitis media. However, the combination of the 2 interventions is no better than either delivered alone. (Read the full article)

Accurately identifying ill hospitalized children with vital signs concerning for clinical deterioration is fundamental to inpatient pediatrics. Normal vital sign ranges for healthy children are useful for outpatient practice but have limited application to detecting deterioration in the hospital setting.

Percentile curves for heart and respiratory rate in hospitalized children were developed and validated. The distributions differed from existing reference ranges and early warning scores. They may be useful to identify vital signs deviating from ranges expected among hospitalized children. (Read the full article)

Acquired widespread pain syndromes of youth are prevalent, disabling, usually unexplained, and untreatable. Small-fiber polyneuropathy causes widespread pain and multisystem complaints in older adults. Some causes are treatable. Neurodiagnostic skin biopsy, autonomic function testing, and nerve biopsy permit objective diagnosis.

It identifies definite (in 59%) and probable (in 17%) small-fiber polyneuropathy among 41 young patients with otherwise-unexplained, childhood-onset widespread pain. It characterizes this new disease’s clinical features, diagnostic, and treatment options. Some cases appeared immune mediated and responded to immunomodulatory therapies. (Read the full article)

Baby-Friendly Hospital Initiative (BFHI) accreditation can have a positive effect on breastfeeding initiation and continuation rates; however, little is known about the effect of BFHI accreditation in populations with high breastfeeding-initiation rates and where infant-friendly practices are common.

BFHI accreditation per se does not improve breastfeeding rates at 1 and 4 months when breastfeeding-initiation rates are high and accredited and nonaccredited hospitals have infant-friendly practices. Baby-friendly practices are more important than accreditation. (Read the full article)

Children with chronic illnesses are at risk for emotional and behavioral problems. Therefore, interventions that focus on coping with the negative consequences of the disease are needed. Evidence-based interventions are limited and often focus on a single diagnosis group.

This study demonstrates the efficacy of a cognitive-behavioral group intervention for children with various chronic illnesses. The findings indicate that the involvement of parents is important to achieve long-term results. (Read the full article)

The reasons why teens are not immunized are related to parental lack of knowledge and the need for provider recommendations.

The reasons for vaccine refusal for human papillomavirus vaccine differ from other teen vaccines, and concerns about its safety are increasing over time. (Read the full article)

Although a growing body of literature suggests links between parental incarceration and negative child outcomes, research that uses representative US samples and focuses on health outcomes is limited.

Using a nationally representative US sample, we examined the association between parental incarceration and young adult mental and physical health outcomes. Results suggest childhood exposure to parental incarceration is associated with increased risk of long-term health problems. (Read the full article)

Bronchiolitis, a leading cause of infant hospitalization, has few proven treatments. A few small studies have reported the beneficial effects of a mixture of 21% oxygen + 79% helium (Heliox). The 2010 Cochrane Review concluded that additional large randomized controlled trials were needed to determine the therapeutic role of Heliox in bronchiolitis.

The Bronchiolitis Randomized Controlled Trial Emergency-Assisted Therapy with Heliox—An Evaluation (BREATHE) trial is the largest multicenter randomized controlled trial to date to investigate the efficacy of Heliox in acute bronchiolitis. The delivery method for Heliox therapy was found to be crucial to its efficacy. (Read the full article)

Chlorhexidine cleansing of the cord can reduce mortality in high-risk settings. Time to separation may increase with topical applications of chlorhexidine; 1 previous community trial quantified this increase and did not measure whether caretakers perceived the delay.

Single and multiple cleansing of the umbilical cord increases time to separation by ~50%, or an average of 2 to 2.5 days. Caretakers were able to detect this difference and expressed dissatisfaction, while still accepting the intervention. (Read the full article)

Racial disparities in health care have been reported in multiple settings, but not thoroughly examined at the clinician level. The frequent occurrence of respiratory tract infections allows the evaluation of differences in the management of children seen by the same clinician.

Racial differences in the management of common pediatric infections occur among children treated by the same clinician. Given persistent concerns about nonjudicious antibiotic use, examining racial differences may inform our understanding of prescribing practices and identify opportunities for intervention.

Head circumference (HC) at birth reflects brain development in utero. However, HC charts used in Canada are either dated, mixed-gender, nonrepresentative of lower gestational ages, or reflective of other populations in the world.

We developed recent and gender-specific reference curves for HC at birth for singletons of 23 to 41 completed weeks’ gestational age, which included a large number of very prematurely born infants, reflecting the current geotemporal Canadian population and advances in obstetric care.

In the era of widespread conjugate vaccine use, the prevalence of bacterial meningitis has declined. However, the impact of this decline on the rate of emergency department visits for viral meningitis and cost of caring for these children is unknown.

There was a decline in the rate of diagnosis of viral meningitis in US children’s hospitals between 2005 and 2011. Most children diagnosed with viral meningitis are treated with antibiotics and are hospitalized, accounting for considerable health care costs. (Read the full article)

Konzo is an irreversible sudden-onset upper-motor neuron disorder affecting children dependent on bitter cassava for food. The neuroepidemiology of konzo is well characterized. Children subsisting on poorly processed bitter cassava without adequate dietary sulfur-based amino acids are especially at risk.

We found a pervasive subclinical neurocognitive effect in children with konzo. This study provides the first evidence we are aware of that a motor proficiency examination can effectively characterize konzo severity. (Read the full article)

In the only previous cross-sectional study, the quality of pediatric guidelines was rated low on the AGREE-II (Appraisal of Guidelines for Research and Evaluation II) scale. The levels of evidence used in pediatric clinical practice guidelines have never been described.

American Academy of Pediatrics guidelines score low on the AGREE-II scale. Approximately one-quarter of recommendations are based on expert opinion or no reference. These findings support the adoption of standards for guideline development and research targeted toward unsupported recommendations. (Read the full article)

Universal hepatitis B virus (HBV) vaccination is a cost-effective strategy to control HBV infection. Giving hepatitis B immunoglobulin to neonates of HBV carrier mothers additionally reduces transmission but is not widely used because of its expense and infrastructure requirements.

Maternal screening for hepatitis B surface antigen and hepatitis B immunoglobulin treatment of neonates of hepatitis B virus carrier mothers could be a cost-effective addition to universal vaccination in settings in which health infrastructure can support such an intervention.

Despite downward trends, the US teen birth rate remains among the highest of developed nations. Childhood maltreatment may place teens at higher risk, but inferences are weak given a lack of prospective study and control for alternative explanations.

Results from the first controlled, prospective study of nulliparous teenagers confirm that victims of maltreatment are more than twice as likely as their nonmaltreated peers to experience a teen childbirth after controlling for demographic confounds and other known risk factors.

Adherence to infant feeding recommendations in the United States is low. The prevalence of early introduction of solid foods (<4 months of age) in the United States has been estimated to range from 19% to 29%.

Mothers’ most commonly cited reasons for early solid food introduction include perception of readiness, hunger, wanting to feed something in addition to breast milk or formula, perception of interest in solids, advice from a clinician, and to improve infant’s sleep. (Read the full article)

Excess tissue oxygenation should be avoided during neonatal resuscitation, especially in premature infants. Delivered oxygen concentrations when using a self-inflating bag (SIB) at oxygen flows <1 L/min remain to be established.

Low oxygen concentrations (30%– 40%) can be delivered with a SIB at an oxygen flow <1 L/min. A practical scheme has been developed correlating the oxygen flow rate and the corresponding delivered fraction of oxygen when using a neonatal SIB. (Read the full article)

The etiology of congenital heart defects (CHDs) is largely unknown. A few studies have suggested that maternal emotional stress around the time of conception may be related to the occurrence of CHDs.

Using a large registry-based data source from Denmark, we found that prenatal exposure to maternal bereavement, as a marker of severe stress exposure, may increase the prevalence of CHDs in offspring. (Read the full article)

Early detection for children with autism leads to better outcomes; early screening is critical. The Modified Checklist for Autism in Toddlers (M-CHAT) is a widely used instrument for early autism screening and is recommended by the American Academy of Pediatrics.

This large study provides empirical support for population screening for autism spectrum disorders and the use of the M-CHAT in primary care settings. This study provides updated results to facilitate use and scoring of the M-CHAT by clinical providers. (Read the full article)

There are no published prospective studies on the natural course and testicular growth in early childhood of spontaneously descended testes after birth compared with scrotal or surgically treated testes in boys with congenital cryptorchidism.

Data collected from this prospective study on the natural course and growth of the spontaneously descended testes add evidence-based data and recommendations on how to clinically manage boys with congenital cryptorchidism. (Read the full article)

Extreme prematurity is a well-established cause of cognitive and motor impairment. There is some evidence that late prematurity and modifiable maternal attributes may negatively influence scholastic achievement, including standardized test performance.

We found that preterm birth significantly increases risk of first-grade failure rate even when the birth is just a few weeks before term gestation. Low maternal education status compounds the effect of prematurity. (Read the full article)

The American Academy of Pediatrics recommends neonates born at <37 weeks’ gestation receive a predischarge Infant Car Seat Challenge, meaning up to 500 000 infants qualify annually. However, little is known about incidence and risk factors for failure in this group.

This is the largest study to date to examine incidence and risk factors for failure of the Infant Car Seat Challenge. We sought to identify infants most at risk for failure to narrow the scope of testing. (Read the full article)

Among adolescents younger than 15, 18% have had sex and 16 000 pregnancies occur annually; among those aged 15 to 17, 30% have had sex and 252 000 get pregnant. Information on the youngest adolescents has not been previously published.

Sexual activity and pregnancy are rare among 10-, 11-, and 12-year-olds, and sex is more likely to be nonconsensual. This arguably represents a different public health issue than sex among older teens, who have a greater need for contraception. (Read the full article)

Infant and neonatal mortality rates in the United States decreased markedly during the twentieth century but have not decreased notably during recent years. There has been an increase in preterm and low birth weight births in recent years.

The lack of decrease in infant and neonatal mortality rates in recent years is due in large part to the increasing proportion of preterm and low birth weight infants, particularly infants <500 g. (Read the full article)

A gap exists with lack of programs to help mothers breastfeed. The 2012 American Academy of Pediatrics' "Policy Statement on Breastfeeding and the Use of Human Milk" re-emphasized breastfeeding as an important public health initiative rather than a lifestyle choice.

Families who receive care in a primary care setting that has implemented a "breastfeeding-friendly" office protocol may have increased rates of exclusive breastfeeding. This study evaluated an accepted clinical protocol in a large, diverse pediatric primary care setting. (Read the full article)

Early readmission of apparently healthy newborns may result from inadequate assessment of a newborn’s readiness for discharge. Knowledge of the frequency, causes, and variation in the rate of newborn readmissions may assist in developing quality improvement interventions.

Feeding problems and jaundice, both potentially preventable, are the leading causes of readmission. Late preterm and early term newborns are more likely to be readmitted and should have close follow-up after discharge from a well baby nursery. (Read the full article)

Delayed anaphylaxis, urticaria, and angioedema to mammalian meat products were first described in the adult population in 2009. Patients with this syndrome who consume mammalian meat typically develop symptoms 4 to 6 hours after ingestion.

Specific diagnoses for children who develop urticaria, angioedema, and idiopathic anaphylaxis are few and far between. We have now shown delayed anaphylaxis, urticaria, and angioedema due to mammalian meat products in the pediatric population. (Read the full article)

Clinically significant bleeding in pediatric immune thrombocytopenia (ITP) is rare. Evidence-based guidelines for the management of pediatric ITP recommend that patients with mild or no bleeding be followed with observation alone.

Many pediatric patients with newly diagnosed ITP continue to be managed in the inpatient setting. Bleeding events are rare in this setting. Although geographic variability exists, intravenous immunoglobulin is the most commonly used inpatient ITP treatment in the United States. (Read the full article)

Advances in the treatment of critically ill infants have increased survival of extremely low/very low birth weight and medically complex infants. Improved survival can result in prolonged mechanical ventilation and sometimes tracheostomy. Current tracheostomy rates for these infants are unknown.

This long-term review of infants discharged from a NICU with tracheostomies is the first to describe tracheostomy rates specifically in extremely low/very low birth weight infants. It focuses on long-term clinical outcomes and comorbidities rather than surgical complications. (Read the full article)

Forgoing artificial nutrition and hydration in children at the end of life is an acceptable practice under some circumstances. However, there is a paucity of pediatric evidence to guide health care providers’ and parents’ decision-making around this practice.

This study describes experiences of parents whose children died after forgoing artificial nutrition and hydration. All parents were satisfied with their decision and believed their child’s death was peaceful. This study adds to the limited evidence to guide clinical practice. (Read the full article)

Recorded music, parent voices, and sung lullabies have been shown to increase oxygen saturation, nonnutritive sucking, and weight gain in premature infants.

Parent-preferred melodies and entrained live rhythm and breath sounds can enhance quiet alert and sleep states, suck response, and oxygen saturation in premature infants and significantly reduce fear and anxiety perception in parents. (Read the full article)

Previous studies have suggested that health care providers, family members, friends, and others play a role in shaping parents’ vaccination decisions. Other research has suggested that the media can influence whether parents decide to vaccinate their children.

Through the application of social network analysis, this study formally examines and quantifies how parents are influenced by the people and sources around them. Its findings suggest that social networks are important, particularly for parents who do not completely vaccinate. (Read the full article)

Electronic health record (EHR) uptake by US hospitals has been slow, including among children’s hospitals. The Health Information Technology for Economic and Clinical Health program, which began in 2011, offers incentives for adoption and meaningful use of EHRs.

Using an annual survey, we evaluated how children’s hospitals have progressed in EHR adoption from 2008 through the start of the Health Information Technology for Economic and Clinical Health program and assessed their ability to meaningfully use EHRs. (Read the full article)

Previous studies have found a relationship between exclusive breastfeeding for ≥6 months and iron deficiency. Little is known about the relationship between total breastfeeding duration, including the period after the introduction of complementary foods, and infant iron status.

Our results suggest that infants with longer total breastfeeding duration may be at risk for iron deficiency. Our findings highlight a clinically important association warranting additional investigation that may inform future guideline updates regarding assessment of risk for iron deficiency in young infants.

Oropharyngeal dysphagia (OPD) prevalence is 19-99%. OPD based on parent-report is associated with gross motor skills in children with cerebral palsy (CP), however this underestimates prevalence. Almost all children with severe CP have dysphagia; little is known about mild CP.

The prevalence of directly assessed OPD in preschool children with CP is 85% (70% in GMFCS I; 100% in GMFCS V). OPD was prevalent even in mild CP. Gross motor functional capacity is strongly related to dysphagia severity and prevalence. (Read the full article)

Cognitive and motor developmental test scores of preterm and late preterm infants increase with gestational age. Developmental test scores in full-term infants have not previously been considered to relate to gestational age.

In a cohort of healthy, full-term infants, 37 to 41 weeks, 12-month mental and psychomotor scores on the Bayley Scales of Infant Development increased with gestational age, suggesting that neurodevelopment is optimal in infants born at 39 to 41 weeks. (Read the full article)

Pulse oximetry testing in newborns can detect asymptomatic cases of critical congenital heart defects and has been added to the US Recommended Uniform Screening Panel. However, the impact that earlier diagnosis may have on survival in this population is unclear.

One-year survival for infants with critical congenital heart defects has been improving over time, yet mortality remains high. Survival has been greatest for those diagnosed after 1 day of age and may increase more with screening using pulse oximetry. (Read the full article)

Parents of children with chronic cough have poor quality of life and often seek multiple consultations. There are few randomized controlled trials on the management of cough or on the efficacy of management algorithms outside of inpatient settings.

In a multicenter, trial, we found that the management of children with chronic cough, in accordance with a standardized algorithm, improves clinical outcomes. Earlier application of the algorithm leads to earlier cough resolution and improved parental quality of life. (Read the full article)

Survival of children with spinal muscular atrophy type 1 is determined by treatment choice: tracheostomy with mechanical ventilation, noninvasive mechanical ventilation, or a palliative approach. Few data are available on life expectancies with different approaches.

The present study provides data comparing therapeutic strategies that affect life expectancy. Clinicians involved in the care of patients with spinal muscular atrophy type 1 should be aware of survival trends while awaiting more definitive therapeutic strategies. (Read the full article)
