The fetal origins of adult disease hypothesis proposes that suboptimal fetal development may condition the later risk of disease, particularly cardiovascular disease. However, this hypothesis has never been tested for diseases of the aging brain.

This first study of its kind provides clinical measures suggesting that small birth size, as an indicator of an adverse intrauterine environment, has lifelong consequences for brain tissue volume and cognitive function. In addition, it shows that the effects of a suboptimal intrauterine environment on late-life cognitive function were particularly present in those with lower educational levels.

Lung ultrasound outperforms conventional radiology in the emergency diagnosis of pneumothorax and pleural effusions. In the pediatric age, lung ultrasound has been also successfully applied to the fluid-to-air transition after birth and to rapid pneumonia diagnosis.

Nasal ventilation has dramatically decreased the need for invasive mechanical respiratory support. This study demonstrates that, after a short trial on nasal continuous positive airway pressure, lung ultrasonography reliably predicts the failure of noninvasive ventilation unlike the conventional chest radiogram.

Adolescents and adults born early preterm have higher blood pressure and altered glucose metabolism compared with their term born peers. Evidence of an atherogenic lipid profile is inconsistent. Whether these risks apply to those born less preterm is not known.

In adolescence, girls have higher blood pressure and boys a more atherogenic lipid profile than their term born peers. Overall, our results are consistent with a dose-response relationship between shorter length of gestation and increasing levels of cardiovascular risk factors. (Read the full article)

Recent reviews suggest that children bullied by siblings are at increased risk of internalizing symptoms. It is not known whether being bullied by a sibling increases risk of psychiatric disorders such as depression, anxiety, and self-harm.

Using a large, community-based birth cohort, we found that being bullied by a sibling is prospectively associated with a doubling in the odds of both depression and self-harm at 18 years in young adults. (Read the full article)

Partner violence victimization is associated with mental and behavioral health effects linked to weight gain. Childhood maltreatment is directly linked to obesity and associated with neuroanatomic and psychosocial changes, which heighten vulnerability to subsequent stressors.

This study finds that dating violence victimization is associated with greater increases in BMI from adolescence to young adulthood among women. Women with previous exposure to childhood sexual abuse are especially vulnerable to dating violence–related increases in BMI. (Read the full article)

Health care–associated infections are harmful, costly, and preventable, yet there remain limited data as to their population incidence among hospitalized neonates and children in the United States.

Incidence rates of central line–associated bloodstream infections and ventilator-associated pneumonia decreased among critically ill neonates and children during a 5-year period in the United States. National efforts to improve patient safety through decreasing HAIs have been effective. (Read the full article)

Puberty suppression has rapidly become part of the standard clinical management protocols for transgender adolescents. To date, there is only limited evidence for the long-term effectiveness of this approach after gender reassignment (cross-sex hormones and surgery).

In young adulthood, gender dysphoria had resolved, psychological functioning had steadily improved, and well-being was comparable to same-age peers. The clinical protocol including puberty suppression had provided these formerly gender-dysphoric youth the opportunity to develop into well-functioning young adults. (Read the full article)

Although frequent utilizers of emergency departments (EDs) are targeted for quality improvement initiatives across the United States, little is known about the health services these patients receive in the ED.

Eight percent of children account for 24% of ED visits and 31% of all costs. Frequent utilizers of pediatric EDs, especially infants without a chronic condition, are least likely to need medications, testing, and hospital admission during their ED visits. (Read the full article)

Influenza leads to respiratory deteriorations in cystic fibrosis (CF) patients. In children, live attenuated influenza virus vaccine (LAIV) is more efficacious than inactivated influenza vaccines, which could be beneficial for CF. Data on the safety of LAIV in this population are scarce.

This study assesses LAIV’s safety in patients with CF and is necessary to determine whether the anticipated benefits associated with LAIV will outweigh potential risks. This can potentially lead to a recommendation for preferential LAIV use in this population. (Read the full article)

Many pediatric acute respiratory tract infections (ARTI) are viral and do not require antimicrobial treatment. Recent estimates of antimicrobial overprescribing for these infections, defined based on the published bacterial disease prevalence among all ARTI, are not available.

Based on the published bacterial prevalence rates for pediatric ARTI, antimicrobial agents are prescribed almost twice as often as expected to outpatients nationally, amounting to an estimated 11.4 million potentially preventable antimicrobial prescriptions annually. (Read the full article)

Childhood vaccinations mildly increase the risk of febrile seizures in the general pediatric population, during specific risk periods. However, vaccinations are common precipitants for (first) seizures in the genetically determined, fever-sensitive Dravet syndrome (formerly severe myoclonic epilepsy of infancy).

This study shows that in most children with epilepsy onset after vaccination, genetic or structural causes of epilepsy can be identified. This claim includes children with Dravet syndrome (~35%) but also children with benign epilepsy or preexistent encephalopathy. (Read the full article)

Behavioral health (BH) screening is known to increase identification of children with BH issues, but in small-scale studies, rates of follow-up after screening have been reported to be low.

This study examines the relationship between BH screening and the receipt of BH services in Massachusetts Medicaid children. Nearly 60% of children identified with BH problems received BH services, but only 30% of newly identified children received BH services. (Read the full article)

Despite child-resistant packaging requirements for most medications and safe storage education for all medicines, tens of thousands of young children are brought to emergency departments and thousands are hospitalized annually after ingesting prescription medications. Targeted prevention efforts may be needed.

Twelve medications were implicated in nearly half of hospitalizations for prescription medication ingestions. Buprenorphine and clonidine were most commonly implicated and had the highest hospitalization rates when accounting for outpatient use. Prevention efforts should focus on most commonly implicated medications. (Read the full article)

Vaccinating youth is among the nation’s highest health care priorities. Despite proven health benefits, human papillomavirus vaccination rates remain low.

This is the first known study to test whether vaccination of high-risk adolescents is related to their or their parents’ previous knowledge levels. In the results presented, neither parental nor adolescent knowledge is related to subsequent adolescent vaccination. (Read the full article)

Evidence from cohort studies has consistently found that universal bilirubin screening is associated with reductions in rates of severe hyperbilirubinemia but has shown variation in other outcomes such as phototherapy use, length of stay, emergency department visits, and readmission rates.

Universal bilirubin screening may not increase neonatal length of stay or postdischarge hospital use. Preexisting trends in health care utilization have an impact on observed effects of universal bilirubin screening. (Read the full article)

Childhood immunization might contribute to an increase in asthma prevalence. Previous studies have been contradictory, and many lack sufficiently large control groups of nonimmunized children.

Pertussis immunization in infancy does not increase the risk of asthma medication in adolescents. Our study presents convincing evidence that pertussis immunization in early childhood can be considered safe with respect to long-term development of asthma. (Read the full article)

The single-family room (SFR) NICU is a major response to improve care and reduce developmental morbidity in preterm infants. However, no studies have examined how and why this model is associated with changes in medical and neurobehavioral outcome.

This study shows improved medical and neurodevelopmental outcome in infants hospitalized in the SFR model of care. More important, improvements occurred specifically in relation to increases in maternal involvement and developmental support afforded by the SFR environment. (Read the full article)

Infants who require positive pressure ventilation at birth are considered to be at risk for subsequent compromise and are recommended to receive postresuscitation care. The supportive evidence and details of this care have not been fully investigated.

We investigate the need for postresuscitation care in infants who require positive pressure ventilation at birth, review the aspects of care needed, and explore the important risk factors most predictive of it. (Read the full article)

In HIV-infected children, decisions to start antiretroviral therapy must weigh immunologic benefits against potential risks. Current guidelines recommend using CD4 percentage and age when deciding to start treatment. Population-level effects of these factors on immunologic recovery are unknown.

Starting antiretroviral therapy at higher CD4 percentages and younger ages maximizes potential for immunologic recovery. However, not all benefits are sustained, and viral failure may occur. Our results help clinicians better weigh immunologic benefits against viral failure risks. (Read the full article)

Various low-risk criteria have been developed to guide management of the febrile young infant (<90 days), but they differ in age criteria, recommendations, and implementation. Therefore, variation in care is likely but has not been previously studied.

There is wide variation in testing, treatment, and overall resource utilization in management of the febrile young infant across all 3 age groups: ≤28, 29 to 56, and 57 to 89 days. There may be opportunities to improve care variation without compromising outcomes. (Read the full article)

Children who have attention-deficit/hyperactivity disorder (ADHD) attending clinical services have poorer outcomes in adolescence on a range of measures. However, it is unknown how early in development these impairments appear, particularly for community-ascertained samples.

At age 6 to 8 years, children in the community with ADHD have significantly poorer mental health, academic performance and social function compared with control children. Children who have impairing ADHD symptoms should be referred early for assessment and intervention. (Read the full article)

Physical activity programs have been shown to have positive implications for children’s cognitive performance and brain structure and function. However, additional randomized controlled trials are needed to determine whether daily physical activity influences executive control and its neural underpinnings.

The randomized controlled trial, designed to meet daily physical activity recommendations, used behavioral and electrophysiological measures of brain function to demonstrate enhanced attentional inhibition and cognitive flexibility among prepubertal children. (Read the full article)

Sleep disorders are common in children and adolescents and have a substantial negative impact on daily life and school performance. Long-term evaluations of the efficacy and safety of pharmacologic treatment options for sleep disorders are lacking in pediatric patients.

These 2 studies provide the first evaluation of the effectiveness and safety of eszopiclone in children and adolescents with insomnia associated with ADHD. Data presented here encompass longer-term (up to 1 year) pediatric exposure to eszopiclone. (Read the full article)

Admissions to the ICU during off-hours (nights and weekends) have been variably associated with increased mortality in both adults and children. Changes in staffing patterns, patient characteristics, or other factors may have influenced this relationship over time.

This study demonstrates in a large, current, multicenter database sample that off-hours admissions to PICUs are not associated with increased risk-adjusted mortality. Admissions in the morning from 6:00 am to 10:59 am are associated with increased mortality and warrant further attention. (Read the full article)

More children with special health care needs are surviving to adulthood and entering the adult health care system. Effective transition of care can promote continuity of developmental and age-appropriate care for these individuals.

Existing studies provide modest transition care support. Methods for providing transition care warrant attention, and future research needs are wide ranging. Consistent and accepted measures of transition success are critical to establishing an adequate body of literature to affect practice. (Read the full article)

In 2003, the US Food and Drug Administration issued warnings about hyperglycemia and diabetes with second-generation antipsychotics (SGAs). Since 2004, hyperglycemic and diabetes risk with SGAs has been stated in product labels, and published guidelines have recommended baseline metabolic screening.

Between 2006 and 2011, 11% of children 2 to 18 years starting an SGA had baseline glucose assessed. Youth at risk for diabetes may not be identified. Further, lack of screening impedes determining the contribution of SGAs to hyperglycemia. (Read the full article)

Cross-sectional research indicates that teen sexting is common, may be associated with other adolescent behaviors such as substance use, does not appear to be a marker of mental well being, and is probably an indicator of actual sexual behaviors.

Although mounting evidence links teen sexting to sexual behavior, little is known about the temporal sequencing of these 2 behaviors. Knowing which comes first will aid tween- and teen-focused health care providers in their interaction with patients and patients’ parents. (Read the full article)

Little is known about how pediatricians communicate with overweight Latino children and their parents regarding overweight and obesity.

Findings suggest that many overweight Latino children and their parents do not receive direct communication that the child is overweight, weight-management plans, culturally relevant dietary recommendations, or follow-up visits. (Read the full article)

The built environment may affect weight status by presenting opportunities or barriers for exercise and nutritious eating. Although there is substantial cross-sectional evidence linking neighborhood factors and childhood obesity, causal uncertainty remains, owing to conceptual and methodological challenges.

This prospective study examined neighborhood influences on obesity during the transition to adolescence, a sensitive period for excess weight gain. Girls living in neighborhoods characterized by physical disorder or increased access to food and service retailers exhibited higher obesity risk. (Read the full article)

Despite breastfeeding recommendations by the World Health Organization and the American Academy of Pediatrics, there is less agreement on appropriate use of infant solid foods. There are currently no well-established dietary guidelines for US infants that are similar to the Dietary Guidelines for Americans (aged >2 years).

Distinct dietary patterns exist among US infants and have differential influences on growth. Use of "Infant guideline solids" (vegetables, fruits, baby cereal, and meat) with prolonged breastfeeding is a promising healthy dietary pattern for infants after age 6 months. (Read the full article)

Restrictive feeding by parents is associated with poorer eating self-regulation and increased child weight status. However, this association could be due to confounding home environmental or genetic factors that are challenging to control.

Differential maternal restrictive feeding is associated with differences in twins' caloric compensation and BMI z score. Controlling for the shared home environment and partially for genetics, these findings further support a true (ie, unconfounded) association between restriction and childhood obesity.

Movie ratings designed to warn parents about violence and sexual content have permitted increasing amounts of each in popular films. One potential explanation for this "ratings creep" is parental desensitization to this content as it becomes more prevalent in movies.

This study adds experimental evidence that parents become desensitized to movie violence and sex and are more willing to allow children to view such content. (Read the full article)

Neonatal circumcision in the United States has been estimated to be performed in ~58% of all neonates, and varies by US geographic region.

This study estimates neonatal and postneonatal circumcision rates among commercially insured males aged 0 to 18 years that were performed in both inpatient and outpatient settings. This study also estimates indications and payments for the procedure. (Read the full article)

Parental smoking cessation helps eliminate children’s exposure to tobacco smoke. A child’s visit to the doctor provides a teachable moment for parental smoking cessation. Effective strategies to help parents quit smoking are available for implementation.

Evidence-based outpatient intervention for parents who smoke can be delivered successfully after the initial implementation. Maximizing parental quit rates in the pediatric context will require more complete and sustained systems-level integration. (Read the full article)

Quality improvement (QI) studies generally do not account for concurrent trends of improvement and it is difficult to distinguish the impact of a multihospital collaborative QI project without a contemporary control group.

A multihospital collaborative QI model led to greater declines in hypothermia and invasive ventilation rates in the delivery room compared with an individual NICU QI model and NICUs that did not participate in formal QI activities. (Read the full article)

Medication errors involving children represent a frequently occurring public health problem. Since 2003, >200 000 out-of-hospital medication errors have been reported to US poison control centers annually, and ~30% of these involve children <6 years of age.

During 2002–2012, an average of 63 358 children <6 years experienced out-of-hospital medication errors annually, or 1 child every 8 minutes. There was a significant increase in the number and rate of non–cough and cold medication errors during the study period. (Read the full article)

Jaundiced newborns without additional risk factors rarely develop kernicterus if the total serum bilirubin is <25 mg/dL. Measuring the bilirubin/albumin ratio might improve risk assessment, but the relationships of both indicators to advancing stages of neurotoxicity are poorly documented.

Both total serum bilirubin and bilirubin/albumin ratio are strong predictors of advancing stages of acute and post-treatment auditory and neurologic impairment. However, bilirubin/albumin ratio, adjusted to the same sensitivity, does not improve prediction over total serum bilirubin alone. (Read the full article)

Professional organizations recommend ultrasound as the initial diagnostic imaging modality for children with suspected nephrolithiasis. Computed tomography utilization for children with nephrolithiasis treated at freestanding children’s hospitals is common and varies substantially by hospital.

The high prevalence and regional variability of CT as the first imaging study for children with nephrolithiasis who presented to emergency departments, outpatient clinics, and hospitals throughout the United States indicate that current imaging practices deviate substantially from guidelines.

Prophylactic indomethacin in extremely low birth weight infants decreases severe intraventricular hemorrhage and patent ductus arteriosus but it is unknown whether concurrent enteral feeding and prophylactic indomethacin is associated with increased risk of spontaneous intestinal perforation.

The combination of prophylactic indomethacin and enteral feeding during the first 3 days after birth does not increase the risk of spontaneous intestinal perforation. (Read the full article)

Perinatal complications predict increased risk for morbidity and early mortality. Evidence of perinatal programming of adult mortality raises the question of what mechanisms embed this long-term effect. Telomere length and perceived facial age are 2 indicators of accelerated aging.

Perinatal complications predicted greater signs of accelerated aging "inside," as measured objectively by leukocyte telomere length, an indicator of cellular aging, and "outside," as measured subjectively by perceived age, an indicator of declining integrity of tissues. (Read the full article)

Delivering competent oral case presentations is an important clinical communication skill, yet effective means of improving trainees’ presentations have not been identified.

Oral presentation feedback sessions facilitated by faculty by using an 18-item competency-based evaluation form early in pediatric clerkships improved medical students’ subsequent oral presentations. Medical schools should consider implementing this evidence-supported practice. (Read the full article)

The population of youth with chronic medical conditions is growing and many attend college. Yet we know little about US colleges’ capacity to identify and care for these youth, nor how transition guidelines and financing models should incorporate college health.

This is the first study to find that although many colleges can provide some clinical care for youth with chronic conditions, few colleges have systems to identify and track these students, elucidating gaps that pediatricians and institutions need to address. (Read the full article)

Neurodevelopment can be adversely affected by viral infections. Human herpesvirus-6 (HHV-6) is similar to cytomegalovirus and can cause central nervous system disease. Congenital HHV-6 infection occurs in ~1% of live births, with unknown neurodevelopmental consequences.

HHV-6 congenital infection is associated with lower scores on the Bayley Scales of Infant Development II Mental Development Index compared with control infants at 12 months of age and may have a detrimental effect on neurodevelopment. (Read the full article)

Randomized controlled trials (RCTs) of intensive clinician-implemented interventions have demonstrated significant improvements in outcomes of toddlers and preschool children with autism spectrum disorder. RCTs of parent-implemented interventions have demonstrated improvements in parent skills, but generally they have not demonstrated effects on children’s outcomes.

This RCT found significantly greater improvements with individual home coaching on child outcome measures of social communication, adaptive behavior, and developmental level. These findings support the efficacy of a parent-implemented intervention using little professional time, which increases potential community viability. (Read the full article)

Studies have shown that reciprocal vocalizations between mother and infant have positive effects on language development. It has been shown that girls acquire vocabulary and language skills earlier than boys.

Mothers more readily respond to their infant’s vocal cues than fathers, and infants show a preferential vocal response to their mothers in the first months of life. Mothers respond preferentially to infant girls versus boys at birth and 44 weeks. (Read the full article)

Studies have shown that setbacks, such as receiving low school grades, lead children to experience negative self-feelings (eg, shame, insecurity, powerlessness). Psychological theory predicts that unconditional regard can buffer this adverse impact of setbacks. However, causal evidence is lacking.

This randomized field experiment shows that briefly reflecting on experiences of unconditional regard buffers children’s negative self-feelings after an academic setback 3 weeks later. Unconditional regard may thus be an important psychological lever to reduce negative self-feelings in youth. (Read the full article)

Previous studies have examined state regulations for child care facilities and found substantial variation among states. None of these studies examined regulations related to healthy sleep practices, which is an important and often overlooked intervention target for obesity prevention.

We reviewed state regulations related to healthy sleep in child care and compared them to recent national recommendations put forth by the Institute of Medicine. We found that many states lacked regulations, highlighting an important and timely opportunity for improvement. (Read the full article)

National adolescent vaccination coverage estimates in 2013 among 13- to 17-year-olds are 86% for Tdap vaccine and 78% for MCV4. Comparatively, coverage with ≥3 doses of HPV vaccine is 38% among girls and 14% among boys.

One-fourth of 11-year-olds had HPV vaccine co-administered with Tdap vaccine, compared with two-thirds who had MCV4 co-administered. Whereas by age 17 years, >92% received Tdap vaccine and MCV4, only half of girls and one-fifth of boys completed HPV vaccination. (Read the full article)

Pneumococcal conjugated vaccines (PCVs) are known to decrease invasive pneumococcal disease in children, but their effect on pneumonia necessitating hospitalization is more variable across study sites, and effects on hospitalization for sinusitis have not been shown previously.

There was a significant decrease in hospitalizations for sinusitis in children <2 years of age, and hospitalization for pneumonia decreased in children aged <5 years after sequential introduction of PCV7 and PCV13. (Read the full article)

Research suggests that appearance-focused messages and exaggerated depictions of sexual activity in the media negatively influence adolescents’ body and sexual self-perceptions. As adolescents increasingly use the Internet to explore their sexuality, health risks related to online behaviors should be identified.

This 4-wave study examined the prevalence and development of 2 receptive and 2 interactive sex-related online behaviors and their relations with adolescents’ body and sexual self-perceptions. It further investigated which parental strategies regarding Internet use may reduce risky sex-related online behaviors. (Read the full article)
