The importance of and interest in childhood mental problems have increased worldwide. There are few population studies on child and adolescent mental health and health-related quality of life (HRQoL).

A social gradient was found in childhood mental health according to maternal education level and social class, but none was found in HRQoL, although children from disadvantaged social classes had somewhat lower HRQoL scores than their more advantaged counterparts. (Read the full article)

Adolescents living in lower-poverty neighborhoods have better mental health than youth in high-poverty contexts, but it is unclear if associations are causal. Furthermore, it is unknown why some youth benefit more than others from moving to more advantaged neighborhoods.

Using an experimental study that randomly assigned families to receive vouchers to move to lower-poverty neighborhoods, we found that recent violent crime victimization adversely modified the mental health effects of moving to better neighborhoods. (Read the full article)

Although the natural course of bilirubin levels has been extensively studied in general neonatal populations, there is a paucity of data regarding bilirubin trends in neonates before the development of significant hyperbilirubinemia.

This study provides data on the natural course of transcutaneous bilirubin before the development of significant hyperbilirubinemia, and on the effect of different demographic and perinatal risk factors on the rate of bilirubin increase in neonates with borderline bilirubin values.

Current human milk fortifiers fail to provide the higher protein intake that is now recommended for feeding human milk–fed infants. There is a desire to avoid the use of powdered products when feeding these infants.

A new ultraconcentrated liquid human milk fortifier that provides more protein than current powdered fortifiers is safe and supports better growth in human milk–fed infants than a powdered fortifier. (Read the full article)

Despite numerous preventive strategies including prophylaxis with 400 IU/day of vitamin D in recent years, the deficiency of vitamin D in infants is still a global health problem.

This study reveals that the risk of vitamin D deficiency is high in exclusively breastfed infants, especially in winter, despite vitamin D supplementation. Therefore, it is suggested that an adjustment of vitamin D dosage for seasonal variation might be necessary. (Read the full article)

Discussing end-of-life (EoL) care with adolescents and young adults (AYAs) is difficult. Often, such conversations are delayed or avoided, but AYAs contemplate EoL issues and want to make decisions about their care. Few established resources exist to help this process.

Results support the use of a developmentally appropriate document that allows AYAs an opportunity to share their choices about EoL care and how they would like to be remembered in the future. (Read the full article)

Social and environmental risks related to substandard housing contribute to adverse health outcomes. Partnerships between the health care and legal systems can help families address such risks and help clinicians understand the legal context of health.

A medical-legal partnership colocated in a pediatric primary care setting identified and treated a large cluster of poor quality, substandard housing. Housing improvements were possible because of strong collaboration between clinicians, attorneys, community partners, and families. (Read the full article)

Patients living in rural versus urban counties encounter different health care environments. Whether these differences result in different health care utilization for rural versus urban infants is not known.

In this study, infants living in rural California counties were hospitalized less often than infants living in urban counties. Among those hospitalized, infants living in rural counties were hospitalized for fewer cumulative days than infants residing in urban counties. (Read the full article)

Today’s adolescents increasingly use the Internet to explore their sexual identity. There is public concern that the Internet, because of its accessibility, affordability, and anonymity, stimulates adolescents to engage in online sexual risk behavior (eg, sending sexual images to strangers).

This 4-wave panel study is the first to delineate the typical development of online sexual risk behavior, its relationship with offline sexual risk behavior, and the factors (eg, sensation seeking, family cohesion, life satisfaction, education, online communication) that predict both behaviors.

Medical advances have prolonged life for children and adolescents with Duchenne muscular dystrophy (DMD), the most common inherited pediatric neuromuscular disorder. Children with this progressive disease surviving to adulthood still face significant threats to their quality of life.

Self-reported psychosocial quality of life was impaired in a significant number (57%) of boys with DMD, unrelated to their need for mobility aids. Concordance between the perceptions of parents and their sons related to psychosocial functioning was fair to poor. (Read the full article)

Pediatric specialists are increasingly involved in prenatal care, particularly for congenital fetal conditions. Questions remain about pediatricians’ role in the management of maternal conditions that may affect postnatal health, and the attitudes of obstetric and pediatric specialists around such care.

Obstetric and pediatric specialists’ attitudes differ substantially regarding pediatricians’ role in providing consultation for maternal conditions that may affect a child’s health postnatally, and regarding whether court authorization may be appropriate when a woman refuses certain treatment recommendations.

Most observational studies from Western populations suggest that blood pressure is positively associated with low birth weight and faster infant growth; however, it is unclear whether these associations are biologically based or contextually specific.

In a developed non-Western setting with relatively little socioeconomic patterning of size or growth, birth weight and infant growth had relatively limited impacts on early adolescent blood pressure, which was more strongly related to recent growth and current size. (Read the full article)

Cerebral edema (CE) occurs frequently during treatment of diabetic ketoacidosis (DKA) in children. Severe, life-threatening CE occurs rarely, but subclinical CE is common. Whether the rate of infusion of intravenous fluids influences the occurrence or severity of CE is unknown.

This study demonstrates that the rate of fluid infusion in children with DKA does not substantially affect MRI measures of CE. Studies assessing measures other than edema formation are necessary to determine whether fluid infusion rates influence DKA-related brain injury. (Read the full article)

Validated questionnaires can improve the identification of psychosocial problems among children. The Strengths and Difficulties Questionnaire (SDQ) 3-4 is a promising option. However, no studies are available that examine the psychometric properties of the SDQ parent form 3-4.

The results of this study show that the SDQ 3-4 is a valid tool for the identification of psychosocial problems in preschool-aged children. (Read the full article)

Previous studies suggest that hospitals under the greatest financial strain may be more prone to adverse events because they have limited resources to invest in quality and safety.

The patient population served, rather than hospital category, best predicts measured quality, underscoring the need for robust risk adjustment when incentivizing quality or comparing hospitals. Thus, problems of quality may not be systemic across hospital categories. (Read the full article)

Heuristics are decision-making aids or shortcuts that ease the task of making a wide variety of decisions in diverse contexts. Little is known about the heuristics that parents of children with serious illness use when confronting difficult decisions.

Parents of children with life-threatening illnesses use several different types of heuristics, explicitly, in making sense of complex situations, making decisions, and communicating these decisions to others. Better understanding of these heuristics may improve communication and decision support. (Read the full article)

Practice characteristics, such as practice size, have been associated with the readiness of adult primary care practices for medical home certification. Little is known about how ready primary care practices for children are for medical home certification.

Primary care practices for children attained only 38% of the infrastructure required for medical home certification. Smaller practice size was significantly associated with lower infrastructure scores. Medical home programs need effective approaches to support practices with limited resources.

Children have been shown to imitate behaviors they see on screen.

Modifying what children watch can improve their observed behavior. (Read the full article)

There is a lack of consensus regarding the optimal investigative approach after a first febrile urinary tract infection. This is because of uncertainty regarding the long-term clinical significance of vesicoureteral reflux and urinary tract infection–related renal scarring.

No ideal diagnostic algorithm exists. We found marked variability in sensitivity and specificity for detection of abnormalities using current protocols. We also highlight the considerable cost differences, both financially and in terms of radiation dose, of different protocols. (Read the full article)

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.

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)

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)

Pacifiers may interfere with breastfeeding and thus are discouraged until 3 to 4 weeks of life, when they are recommended for sudden infant death syndrome risk reduction. Hospitals are restricting pacifier distribution as part of the Baby-Friendly Hospital Initiative.

We describe a temporal association between reduced exclusive breastfeeding and pacifier restriction. This observation encourages research on breastfeeding promotion and the effects of pacifiers and pacifier restriction on breastfeeding. (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.

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)

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)

Studies suggest that young adults have worse access to health care, use less primary care, and visit emergency departments more frequently than adolescents. Whether these differences are present between adolescents and young adults with asthma is unknown.

Young adults with asthma were less likely to have a usual source of care and use primary care. In contrast, they were more likely to use the emergency department. Adjusting for insurance coverage reduced these differences partially but not completely. (Read the full article)

Heated, humidified high-flow nasal cannula (HHHFNC) is a noninvasive mode of respiratory support that is commonly used in the majority of US NICUs. No large randomized trial has evaluated safety or efficacy of HHHFNC.

This large randomized controlled trial suggests that HHHFNC is as effective as nCPAP for noninvasive respiratory support and can be safely applied to a wide range of neonates. (Read the full article)

Botulinum spores are ubiquitous, found in the soil of most countries worldwide, and also in honey. It is well established that ingestion of honey by children aged <1 year can lead to infant botulism.

This study examines the prevalence of honey pacifier use among a pediatric population aged <1 year. We also assessed parental knowledge of the dangers of giving honey to children in this age group. (Read the full article)

Infants with a diverse gut microbial flora are less likely to develop eczema and allergy.

Parental sucking of their infant’s pacifier is associated with a reduced risk of allergy development and an altered oral flora in their child. Transfer of oral microbes from parent to infant via the pacifier might be used in primary prevention. (Read the full article)

Neonatal mortality rate and causes of death have been relatively stable in recent years. Decision-making practices preceding death of sick neonates affect the circumstances of death. These practices vary worldwide according to the team approach and local population background.

Although our population is mostly religious, we observed a decline in maximal intensive care along with increasing redirection of care over a decade. Changes in the team approach and increasing level of parental involvement influence type and duration of treatment. (Read the full article)

Many US children aged 6 to 24 months who would be classified as low weight-for-age by the Centers for Disease Control and Prevention 2000 reference will be classified as normal weight-for-age by the World Health Organization 2006 standard.

Children who will be reclassified from low to normal weight-for-age using the World Health Organization growth standard are at higher risk of adverse health outcomes than children who are not low weight-for-age by the Centers for Disease Control and Prevention reference. (Read the full article)

There are ethnic differences in lung function, with white people generally having higher values of FVC and FEV₁ than people of South Asian origin, whereas differences in forced expiratory flows are absent or less marked. The underlying reasons are unknown.

Lung function differences were not explained by cultural, socioeconomic, or perinatal factors, nor by environmental exposures or wheezing illness. This suggests that genetic factors are responsible, and supports the use of ethnicity-specific prediction equations for children of South Asian origin. (Read the full article)

Pediatric palliative care (PC) can be beneficial to children with life-threatening conditions and their families by providing symptom management and control, sibling support, bereavement services, spiritual guidance, support in decision-making about limiting burdensome medical interventions, and advance directives.

Little is known about actual receipt of PC by dying children. This study compares characteristics of dying children by receipt of PC and highlights underserved patient groups who could be targeted to improve access. (Read the full article)

Elevated blood pressure (BP) has long-term influence on the atherosclerotic process. The relative predictive ability of the standard BP definition endorsed by the National High Blood Pressure Education Program and the recently proposed 2 simplified definitions has not been studied.

Simplified pediatric BP tables predict risk of high adult arterial stiffness as well as the complex table does. These simple screening tools could be used for identifying pediatric subjects at risk and for intervening to improve adult cardiovascular outcomes. (Read the full article)

Racial and ethnic differences exist in age at diagnosis and early access to mental and behavioral health services among children with autism spectrum disorders (ASDs). ASDs are also associated with increased rates of other medical comorbidities that may require specialty care.

Significant racial and ethnic differences in use of specialty care and specialty procedures exist among children with documented ASD. (Read the full article)

The number of overweight and obese children has dramatically increased in recent decades. To combat this trend, information on possible gender-related differences in risk factors of overweight and obesity is critical.

This study examines associations of gender and physiologic and behavior measurements with potential cardiovascular risk. Lunch consumption and screen time were associated with weight; however, other associations with weight differ by gender. This information can be used to tailor future interventions.

Evaluating for elevations in alanine aminotransferase (ALT) is a common screening test for the presence of nonalcoholic fatty liver disease (NAFLD). NAFLD is less common among non-Hispanic blacks. Better predictors of NAFLD are needed to identify individuals in most need of screening.

Relative to other ethnicities, metabolic syndrome and insulin resistance performed poorly at identifying non-Hispanic black adolescents with ALT elevations. The presence of metabolic syndrome may therefore not be an adequate trigger for NAFLD screening. Triglyceride elevations performed similarly between groups in identifying ALT elevations.

The intestinal microbiome may play a role in immune system maturation, and it has been postulated that early-life probiotic administration may reduce the risk of allergies and asthma in childhood. To date, however, results from clinical trials have been inconsistent.

In this meta-analysis, administration of probiotics in early life may reduce total immunoglobulin E level and protect against atopic sensitization but do not seem to protect against asthma/wheezing. Future trials should carefully select probiotic strains and include longer follow-up. (Read the full article)

Latino children are diagnosed with autism spectrum disorders (ASDs) less often and later than white children. Primary care pediatricians (PCPs) may play an important role in early ASD identification for Latinos.

PCPs find it more difficult to assess for ASDs in Latinos with Spanish primary language, view Latino parents as less knowledgeable about ASDs, and experience frequent barriers to ASD diagnosis in Latino patients. Many PCPs do not offer recommended screenings in Spanish. (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)

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

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

Previous studies have shown that nonmedical exemptions (NMEs) to immunization cluster geographically and contribute to outbreaks of vaccine-preventable diseases such as pertussis. The 2010 pertussis resurgence in California has been widely attributed to waning immunity from acellular pertussis vaccines.

This study provides evidence of spatial and temporal clustering of NMEs and clustering of pertussis cases and suggests that geographic areas with high NME rates were also associated with high rates of pertussis in California in 2010. (Read the full article)

Caregiver behavioral symptom ratings are frequently used to assist in diagnosing childhood behavioral disorders. Although behavioral disorders are highly comorbid with learning disabilities (LDs), little work has examined the utility of caregiver ratings of learning concerns for screening of comorbid LD.

The validity of a time- and cost-efficient caregiver rating of academic concerns (Colorado Learning Difficulties Questionnaire) was examined. The screening measure accurately predicted children without LD, suggesting that the absence of parent-reported difficulties may be adequate to rule out overt LD. (Read the full article)

Links between clinically diagnosed sleep problems and adverse behavioral outcomes are well documented. However, in nonclinical populations, causal links between disrupted sleep and the development of behavioral difficulties are far from clear.

Seven-year-old children with nonregular bedtimes had more behavioral difficulties than children who had regular bedtimes. There were clear dose–response relationships, and the effects of not having regular bedtimes appeared to be reversible. (Read the full article)

A large and growing literature has demonstrated significant associations between the use of spanking and later child aggression, but we know less about paternal spanking, effects of spanking on cognitive development, and longer-term effects.

Accounting for a broad array of risk factors, spanking predicts both aggression and receptive vocabulary across the first decade of life. Importantly, we include paternal spanking, cognitive outcomes, and a longitudinal span longer than that of much of the literature. (Read the full article)

Psychosocial stress in childhood has been associated with a greater risk of future overweight, although the associations have not always been consistent, the types of psychosocial stressors have often been somewhat extreme, and moderators of the association have rarely been examined.

Experiencing many negative life events in childhood, particularly with chronicity or events that are family health related, increases risk of overweight by age 15 years. Maternal obesity and greater delay of gratification for food each intensify this risk. (Read the full article)

Screen time has risen to unprecedented levels among youth. Greater television time is known to be associated with gains in pediatric adiposity, but few studies have examined the longitudinal relations of other forms of screen-based media with weight gain.

Among adolescents aged 9 to 19 years, television viewing was the type of screen time most consistently associated with gains in BMI. However, time with digital versatile discs/videos and video/computer games was also associated with gains in BMI among girls. (Read the full article)

The demand for donor kidneys for transplantation exceeds supply. En bloc kidney transplantation and donation after determination of circulatory death from pediatric donors increases the potential donor pool.

Newborn infants undergoing elective withdrawal of life support in the NICU are a previously unrecognized source of potential kidney donors. (Read the full article)

Studies assessing the accuracy of brief screening tools for postpartum depression have been conducted among adult women; however, no similar validation studies have been conducted among adolescent mothers. Accurate and valid brief depression screening tools are needed for adolescent mothers.

We found that the 10-item Edinburgh Postnatal Depression Scale (EPDS) and 2 subscales, the EPDS-7 and EPDS-2, are highly accurate at identifying postpartum depression among adolescent mothers. In pediatric settings with limited time and resources, these brief scales have potential to be used as effective depression screening tools. (Read the full article)
