Diabetes during pregnancy has been associated with general development impairments in offspring; however, associations between autism and maternal diabetes have been inconsistent. Few studies have examined related conditions accompanied by underlying increased insulin resistance and their association with developmental outcomes.

This population-based study in young children provides evidence that maternal metabolic conditions are a risk factor for autism, developmental delay without autistic symptoms, and impairments in several domains of development, particularly expressive language, after adjusting for sociodemographic and other characteristics.

Alcohol consumption during adolescence and early adulthood has been associated with an increased risk of biopsy-confirmed benign breast disease (BBD), an established risk factor of breast cancer.

This is the first study to analyze the association between adolescent alcohol consumption and risk of biopsy-confirmed proliferative BBD by adolescent folate intake. The result provides no evidence for protective effects of adolescent folate intake on risk of alcohol-associated BBD. (Read the full article)

In utero exposure to glucocorticoids in animal models influences vascular development. Studies in young adults have shown that exposure to antenatal glucocorticoids alters glucose metabolism, but it is not known whether there are any cardiovascular effects.

Glucocorticoid exposure is associated with a localized increase in aortic arch stiffness, similar in magnitude to term-born individuals a decade older. The change in stiffness does not relate to changes in glucose metabolism that were also evident in this cohort. (Read the full article)

The presumed causes of neonatal deaths globally have remained unchanged over the past decade and include infections (~30%), prematurity (~30%), and asphyxia (~25%). Great uncertainty surrounds these estimates and, in addition, cases are likely misclassified as stillbirths.

These observational findings indicate that asphyxia accounts for a much higher percentage (60% of early deaths). Prematurity (18%), low birth weight (8%), and overt infection are much less common. The 5-minute Apgar score is an unreliable indicator of birth asphyxia. (Read the full article)

High or low lymphocyte counts at birth have been reported as a marker for subsequent intraventricular hemorrhage, retinopathy of prematurity, and periventricular leukomalacia. However, this conclusion is questionable because reference ranges for lymphocyte counts have not been constructed by using large numbers of neonates.

This study provides reference ranges for lymphocytes of neonates. A high count at birth is associated with early onset sepsis and IVH and a low count with early onset sepsis, IVH, and retinopathy of prematurity. Among neonates with birth asphyxia, a low count identifies a high risk for death. (Read the full article)

Estimates of youth participation in strangulation activity, commonly referred to as the "choking game," range from 5% to 11%. Previous studies have documented correlations between youth choking game participation and health risks such as substance use and mental health issues.

Among Oregon eighth-graders surveyed, >6% had ever participated in the choking game. Participation was linked to poor nutrition and gambling among females, exposure to violence among males, and sexual activity and substance use among both genders. (Read the full article)

Nonadherence to antiretroviral therapy among children and youth with HIV is a frequent problem that can result in treatment failure and disease progression for this population. Children and adolescents face different barriers to adherence than adults infected with HIV.

Few studies have examined specific barriers to adherence as reported by children with perinatally acquired HIV and their caregivers. This report examines the agreement between child and caregiver perceptions of adherence barriers and the factors associated with these barriers. (Read the full article)

Cumulative social factors in childhood have been associated with obesity in adulthood. Little is known regarding the role of accumulation of social stressors and obesity in early life.

Cumulative social adversities were associated with increased odds of early-onset obesity among girls. In addition, those with a higher number of stressors at a single time period had elevated odds for obesity by 5 years of age. (Read the full article)

As a result of safety and environmental concerns about mercury, aneroid sphygmomanometers have replaced mercury-filled devices for blood pressure measurements. Despite this change, few studies have compared the 2 devices.

Little clinical variation exists between blood pressure measurements obtained from an aneroid or mercury device, suggesting that either device could be used in a research or clinical setting. (Read the full article)

Cross-sectional studies have demonstrated associations between the white matter injury and cognitive impairment in very preterm born children. Longitudinal studies confirmed the relationships between cerebral MRI at term and neurodevelopmental outcomes at up to 2 years old.

White matter injury (but not gray matter injury) on term MRI predicted cognitive impairments of very preterm born infants at 9 years old. Qualitative assessment of white matter signal intensities showed limited predictive values of cognitive impairments. (Read the full article)

Disparities are known to exist in the prescription of opioid analgesics among racial and ethnic groups in the management of postoperative, cancer, and emergency department pain in patients across all ages, including children.

Race is associated with an unequal burden of perioperative pain and opioid adverse effects in children. Relatively, African American children had higher postoperative pain, and Caucasian children had higher incidences of opioid related adverse effects. (Read the full article)

Although several randomized trials have examined the efficacy of serotonin receptor inhibitors in the treatment of repetitive behaviors, there still remains clinical uncertainty as to whether these agents are effective in treating such behaviors in children and adults with autism spectrum disorders.

The goal of this meta-analysis was to examine randomized trials of serotonin receptor inhibitors for treating repetitive behaviors in autism spectrum disorders. Although a small but significant effect of these agents was observed, this effect is likely due to the selective publication of trial results. (Read the full article)

Following a rapid increase from 1980 to 2001, the prevalence of obesity among school-age children and adolescents in the United States has plateaued. Few studies have examined obesity trends among younger children in the past decade, and findings are inconsistent.

Among children aged <6 years at this multisite pediatric practice, the prevalence of obesity was fairly stable during 1999–2003, but substantially decreased during 2004–2008. This decrease was smaller among children insured by Medicaid than children insured by non-Medicaid health plans. (Read the full article)

Existing clinical research policy does not guarantee availability of results. Registration on the Web site ClinicalTrials.gov and the Food and Drug Administration Amendments Act improved transparency in pediatric clinical research. Registration and publication remain voluntary for many trials involving children.

Only 29% of completed registered studies and 53% of National Institutes of Health–funded trials involving children were published. Numbers of studies are increasing. Registration and posting of results on ClinicalTrials.gov should be mandatory for all studies involving children. (Read the full article)

The National Vaccine Advisory Committee highlighted the importance of settings complementary to the medical home for immunization delivery among adolescents, including school-based health centers (SBHCs). The effectiveness and cost of recall for immunizations in SBHC settings has not been studied.

SBHC-based recall was effective in improving immunization rates among adolescents, with effects sizes exceeding those achieved in practice settings. Average costs per child who was immunized ranged from $1.12 to $2.34 in 3 schools, but was $6.87 in 1 school. (Read the full article)

Primary care settings provide an important venue for early detection of substance use and intervention, but adolescent screening rates need improvement. Screening and brief interventions appear effective in reducing adult problem drinking but evidence for effectiveness among adolescents is needed.

A computer-facilitated system for screening, feedback, and provider brief advice for primary care can increase adolescent receipt of substance use screening across a variety of practice settings, and shows promise for reducing adolescents’ use of alcohol and cannabis. (Read the full article)

Conflicting results exist concerning long-term outcome in healthy infants with metabolic acidosis at birth.

Neonates who appear well after perinatal metabolic acidosis do not have an increased risk of neurologic or behavioral problems in need of referral actions or pedagogic arrangements at the age of 6.5 years. (Read the full article)

Dimenhydrinate, an antihistaminic agent, is a widely used drug in Canada and Europe. It limits stimulation of the vomiting center via the vestibular system. Multiple studies have shown its effectiveness in the treatment of vertigo and postoperative nausea and vomiting.

Dimenhydrinate, when given orally, did not significantly decrease the frequency of vomiting in children with acute gastroenteritis compared with placebo. The reported adverse effect proportions were similar for the dimenhydrinate and placebo groups. (Read the full article)

Treatment of adolescent migraine remains a significant unmet medical need. In adults, the combination of sumatriptan and naproxen sodium has demonstrated superior efficacy, with similar tolerability, to its components in the acute treatment of migraine.

This study constitutes the first large-scale, placebo-controlled evidence for the acute relief of adolescent migraine pain and associated symptoms with an oral medication. (Read the full article)

Omega-3 fatty acids (O3FA) are commonly used as complementary treatments in pediatric psychiatric disorders, including Tourette’s disorder (TD), and are well known to have anti-inflammatory properties. However, no studies to date have examined the effects of O3FA on pediatric TD.

This is the first double-blind, placebo-controlled clinical trial of O3FA in pediatric TD. The results indicate that O3FA supplementation may be beneficial in the reduction of tic-related impairment for some children and adolescents with TD, but not tics per se. (Read the full article)

Batteries, especially button batteries, are an important source of pediatric injury. Recent reports suggest that fatal and severe button battery ingestions are increasing.

An estimated 3289 battery-related ED visits occurred annually among US children <18 years of age, averaging 1 visit approximately every 3 hours. The number and rate of visits increased significantly during the 20-year study period, driven by increases during the last 8 study years. (Read the full article)

Some researchers have suggested that individuals with Down syndrome (DS) are protected from atherosclerotic disease; however, recent data from 2 large cohort studies of individuals with DS are significant for increased mortality from ischemic heart disease and cerebrovascular disease.

This study compares lipid profiles among children with DS and their siblings, highlighting the presence of a less favorable lipid profile in this high-risk population. (Read the full article)

Previous research on injuries related to bottle, pacifier, and sippy cup use has largely focused on case reports of infant injuries or fatalities attributed to pacifiers or pacifier parts causing asphyxiation or to bottle warming causing burns.

This study is the first to use a nationally representative sample to investigate the range of injuries requiring emergency department visits associated with bottles, pacifiers, and sippy cups among children aged <3 years. (Read the full article)

Youth violence and alcohol misuse are a preventable public health problem. Previous studies have demonstrated the efficacy of brief interventions in the emergency department (ED) in reducing alcohol misuse and related consequences among older adolescents and adults.

This study supports the efficacy of brief interventions in the ED in reducing peer aggression and victimization 12 months after ED visit. The previous reductions in alcohol consequences noted at 6 months follow-up were not sustained at 12 months. (Read the full article)

Traditional health-risk behaviors, such as problem drinking, smoking, marijuana use, and unsafe sexual behavior are interrelated and not isolated events in the life of adolescents. New health-risk behaviors are emerging: risky music-listening behaviors, which may induce hearing loss.

Risky music-listening behaviors are highly associated with traditional health-risk behaviors. Risky MP3-player listeners are often cannabis users. Frequent visitors of music venues are less often cannabis users, but are often binge drinkers and have sexual intercourse without using a condom. (Read the full article)

Infants weighing 501 to 1500 g are at high risk for mortality and for neonatal morbidities associated with both short- and long-term adverse consequences.

Mortality and major neonatal morbidity in survivors decreased for infants 501 to 1500 g between 2000 and 2009. However, in 2009, a high proportion of these infants still either died or survived after experiencing ≥1 major neonatal morbidity. (Read the full article)

Survival of children born with Down syndrome has been improving, but few studies have used population-based data to examine the influence of fetal and maternal characteristics on survival.

This study examined predictors of survival for children born with Down syndrome using population-based data from the UK Northern Congenital Abnormality Survey and shows that year of birth, gestational age, birth weight, and presence of additional anomalies influence survival status.

Although soy protein–based infant formula is known to support physical growth equal to that of infants fed cow's milk–based formula, data are lacking on developmental status of infants fed soy formula compared with breast milk or milk formula.

Infants fed soy protein–based formula scored within normal limits on standardized developmental testing and did not differ from infants fed cow’s milk–based formula. Breastfed infants have a slight advantage on cognitive development compared with formula-fed infants. (Read the full article)

New, effective approaches to obesity prevention are urgently needed. Social network interventions warrant our attention. Social networks play a significant role in adult and adolescent obesity. The role of social networks in pediatric obesity has not been examined.

Afterschool friendship ties play a critical role in setting physical activity patterns in children as young as 5 to 12 years. Children’s activity levels can be changed by the activity level of their social network during a 12-week afterschool program. (Read the full article)

Although morbidity-free survival for preterm infants has remained constant in US NICUs when assessed collectively, morbidity-free survival differs among centers. Center-specific practices before, at, or after delivery might affect outcomes of the most premature infants.

Our findings suggest that the approach taken to infants at the limits of viability is associated with outcomes of more-mature infants. Identifying centers with higher survival and lower morbidity might lead to identification of key practices to improve morbidity-free survival. (Read the full article)

Observation studies and short-term prospective intervention studies have shown that physical activity positively affects the accrual of bone mass and size during growth; however, fracture risk has not been evaluated.

This study reports the long-term results of a prospective intervention with increased physical activity at a population-based level and for the first time evaluated the clinical relevant end point, fracture risk. (Read the full article)

There is a paucity of controlled studies of recombinant factor VIIa (rFVIIa) use for off-label indications in pediatric patients. Data on the use of off-label rFVIIa, including safety and efficacy, are mostly limited to case reports or small case series.

This is the largest reported case series of off-label rFVIIa in pediatric patients from a well-designed, representative, and rigorously audited registry of rFVIIa use and describes the indications for use, dose administered, adverse events, and outcomes in 388 patients. (Read the full article)

Although obesity is correlated with levels of systolic and diastolic blood pressure, there is little evidence if the increases in obesity over the last 40 years have resulted in increased blood pressure levels.

Despite increases in obesity in Bogalusa, Louisiana between 1974 and 1993, there was no increase in systolic or diastolic blood pressure levels. It should not be assumed that trends in high blood pressure have paralleled those for obesity. (Read the full article)

Preterm infants are at a high risk for retinopathy of prematurity (ROP). Several postnatal factors are well known to be associated with ROP. However, the relationships between antenatal or maternal risk factors and ROP are poorly understood.

This study used a large cohort database to study the influence of maternal gestational hypertension and preeclampsia on ROP in preterm infants. The results showed that preeclampsia, but not gestational hypertension, was associated with a reduced risk of ROP in preterm births. (Read the full article)

The causes of Perthes disease are unknown. There is considerable evidence that the disease has a vascular mechanism, although the nature of this is unknown. There is some suggestion that affected individuals may have a heightened cardiovascular risk in adulthood.

Children with Perthes disease have reduced vascular caliber, which is independent of body height, and abnormal functional vascular measures. These findings may be important in the mechanism of disease and may have implications on long-term vascular morbidity. (Read the full article)

Most mothers in the United States do not meet recommendations for exclusive breastfeeding; however, little is known about how long mothers intend to exclusively breastfeed or how hospital practices affect achieving these intentions.

Most mothers who want to exclusively breastfeed intend to do so for ≥3 months, but the majority are not meeting their intended duration. Mothers are more likely to achieve their intended duration when their infant is not supplemented in the hospital. (Read the full article)

Previous cohorts of extremely low birth weight adolescents have assessed their health status similar to that of normal birth weight controls.

Extremely low birth weight adolescents born in the 1990s assess their health similar to controls but report less risk taking. Extremely low and normal birth weight children rate their health to be poorer at 8 than at 14 years. (Read the full article)

The rapidly rising prevalence of overweight and obesity among children and adolescents over the past 4 decades is a significant public health concern. Experts urge pediatric health care providers to provide routine obesity screening and counseling.

We provide the first nationally representative estimates of the rate of screening and counseling for adolescent obesity by pediatric health professionals. We also examine how socioeconomic factors and access to health care affect whether adolescents receive these services. (Read the full article)

Group B Streptococcus (GBS) is a common cause of meningitis in young infants. Studies from the 1980s revealed that GBS meningitis resulted in substantial mortality and reported that survivors of the infection had a high likelihood of adverse neurodevelopmental outcome.

Contemporary long-term outcomes for children surviving GBS meningitis reveal that 56% are functioning normally. The remainder sustained mild-to-moderate (25%) or severe (19%) neurodevelopmental impairment, highlighting the need for GBS prevention and for ongoing developmental follow-up for GBS meningitis survivors.

Known rates of nonsuicidal self-injury, hurting oneself without the intent to die, are between ~7% and 24% in samples of early adolescents and older adolescents, yet research has not reported rates for youth younger than 11 years old.

Children as young as 7 years old report engaging in nonsuicidal self-injury. There is a grade by gender interaction for nonsuicidal self-injury, such that ninth-grade girls report the greatest rates of engagement and do so by cutting themselves. (Read the full article)

Neonatal hearing screening occasionally fails because of several perinatal and neonatal factors. However, the effect of mode of delivery on hearing screening has not yet been established.

We show significantly more failures on hearing screening in cesarean delivery infants. Hence, the timing of screening after cesarean delivery should preferably be postponed beyond 48 hours to improve success rate, minimize maternal anxiety, and decrease costs. (Read the full article)

There are limited cross-sectional data from observational studies of adolescents showing that regular participation in physical activity is associated with a higher quality of life status, whereas time spent in screen-based entertainment is associated with a poorer quality of life.

Adolescents who were physically active (particularly engaging in outdoor activity) over a 5-year period had higher quality of life than their less active peers. Conversely, high levels of screen-based entertainment over 5 years negatively affected quality of life status. (Read the full article)

Early speech and language delays are risk factors for later developmental and social difficulties. It is easier to identify them retrospectively than prospectively. Population characteristics and prevalence rates make screening problematic.

Using data from a birth cohort, this study identifies predictors of language performance at 5 years and 4 patterns of change between 3 and 5 years, comparing those who change with those whose profile remains low across time points. (Read the full article)

Chronic fatigue syndrome (CFS) is a disabling illness. Some children with chronic disabling fatigue are housebound. Some primary care physicians find making the diagnosis of CFS difficult.

Chronic disabling fatigue is more common in 13-year-olds than previously realized with a population prevalence of ~2.0%. Chronic disabling fatigue in teenagers is more common in those with higher levels of early family adversity. (Read the full article)

Literature about polymorphic expression of an apparent life-threatening event (ALTE), particularly that concerning discrimination between ALTE with evident cause and idiopathic ALTE, is scarce. Relationships between SIDS and ALTEs have been supposed but data are still controversial and no genetic data are available.

Genetic analysis (5HTT and MAOA) on ALTEs and idiopathic ALTEs discriminated the 2 syndromes and found a link between the idiopathic form and SIDS. Consequently, we hypothesized that the 2 latter syndromes could be different phenotype expressions of a common genetic base. (Read the full article)

Prevalence estimates for neurologic and neurodevelopmental disorders in children vary widely, and there is uncertainty as to what extent the individual disorders overlap. Most previous prevalence studies have been based on survey data and not on specialist-confirmed diagnoses.

This study used nationwide register data to determine the proportions of Norwegian children diagnosed with autism spectrum disorder, attention-deficit/hyperactivity disorder, epilepsy, and cerebral palsy and to study how the disorders overlap. All diagnoses were specialist-confirmed. (Read the full article)

Emphasis on preventing central line-associated bloodstream infections (CLABSIs) in US health care facilities and prophylactic antifungal medication use in neonates may impact incidence of Candida spp. CLABSIs. However, data on trends in incidence of neonatal Candida spp. CLABSIs are lacking.

Data from a large sample of US NICUs was analyzed to assess trends in incidence over time. This analysis provides a description of the epidemiology of Candida spp. CLABSIs in a national health care-associated infections surveillance system. (Read the full article)

Febrile infants in the first 90 days may have life-threatening serious bacterial infection. Well-appearing febrile infants with serious bacterial infections cannot be distinguished from those without by examination alone. Variation in care resulting in both undertreatment and overtreatment is common.

The systemwide implementation of an evidence-based care process model for the care of febrile infants in Intermountain Healthcare was associated with increased delivery of evidence-based care, improved infant outcomes, and lower costs. This model adopted nationally can improve value. (Read the full article)

There is no literature on the concentrations of vitamin B₆ vitamers in cerebrospinal fluid of preterm and term newborn infants. This knowledge, however, is highly important, because vitamin B₆ plays a pivotal role in brain development and functioning.

In cerebrospinal fluid of newborn infants, B₆ vitamer concentrations are strongly dependent on postmenstrual age, indicating that vitamin B₆ homeostasis in brain differs between preterm and term newborns. This has implications for the evaluation of epilepsy and vitamin B₆ deficiency. (Read the full article)

Neonatal hyperbilirubinemia may progress to bilirubin encephalopathy. Findings from previous studies on long-term development of neonatal hyperbilirubinemia are conflicting.

Using Ages and Stages Questionnaire, we observed no association between bilirubin exposure and overall development in 1- to 5-year-old children who in the neonatal period had total serum bilirubin level ≥25 mg/dL and no or only minor neurologic symptoms. (Read the full article)
