Impaired fetal growth is an independent risk factor for cardiovascular diseases in adulthood and is associated with arterial wall thickening, a noninvasive measure of subclinical atherosclerosis, in early childhood. No preventive strategy has been identified.

Dietary omega-3 fatty acid supplementation in early childhood prevented the association of impaired fetal growth with arterial wall thickening, suggesting that this early-life intervention may mitigate the risk of cardiovascular disease in those with impaired fetal growth. (Read the full article)

Childhood gender nonconformity has been associated with poorer relationships with parents, but it is unknown if childhood gender nonconformity is associated with childhood abuse or with posttraumatic stress disorder.

We identify gender nonconformity before age 11 years as a risk indicator for physical, sexual, and psychological abuse in childhood and lifetime probable posttraumatic stress disorder in youth. (Read the full article)

Parent-infant bed-sharing is a common behavior of breastfeeding mothers and various ethnic groups. Under certain circumstances, it is associated with an increased risk of sudden infant death. Blanket prohibitions against bed-sharing conflict with breastfeeding promotion and inhibit safe bed-sharing discussion.

Bed-sharing and sofa-sharing were almost mutually exclusive. Pakistani families avoided sofa-sharing and hazardous bed-sharing, and have a very low rate of sudden infant death syndrome. White British families were more likely to smoke, drink alcohol, and sofa-share with their infants. (Read the full article)

The number of individuals diagnosed with autism spectrum disorders (ASDs) continues to increase in the United States and other developed countries. Most prevalence estimates indicate that ASD is diagnosed less commonly in Hispanic individuals compared with non-Hispanic (NH) white populations.

Prevalence of ASD in Arizona’s population-based cohort is higher than reported previously. Prevalence in the Hispanic population and NH white population increased significantly over time, with a significant decrease in the gap between Hispanic and NH white prevalence. (Read the full article)

There is evidence of an impaired respiratory regulation in SIDS, in which serotonergic and noradrenergic neurons are involved. Monoamine oxidase A is the enzyme that degrades both neurotransmitters, and genetic variation of this gene might contribute to SIDS.

Alleles with weak effect on the monoamine oxidase A gene activity (*2/*3) appear to be associated with sudden infant death syndrome in boys. This association is strongest in infants who died at the age with the highest SIDS prevalence. (Read the full article)

Infantile colic affects almost 10% of all infants and is characterized by crying and fussing in an otherwise healthy and well-fed infant. Prenatal exposure to tobacco smoking is a risk factor, but it is unclear whether nicotine causes the association.

Infants exposed to nicotine replacement therapy during pregnancy had elevated infantile colic risk of the same magnitude as infants exposed to tobacco smoking. Intrauterine exposure to nicotine may play a causal role in the pathogenesis of infantile colic. (Read the full article)

Studies in the Netherlands show that pubertal blockade at Tanner 2/3 prevents unwanted sex characteristics and improves psychological functioning. Endocrine Society guidelines (2009) recommend pubertal suppression for adolescents with gender identity disorder until approximately age 16.

This is the first study of a US cohort of children and adolescents with gender identity disorder. Patients were referred for medical treatment to a pediatric center that supports a multidisciplinary Gender Management Service. (Read the full article)

General measures discourage all self-referrals to the emergency department. For adults, self-referral to the emergency department has been associated with nonsevere disease, whereas severity of illness of self-referred children is still unknown.

One in four parents properly judged and acted on their febrile child’s illness by presentation to the emergency department on their own initiative. Measures to discourage parents from self-referral may potentially result in delayed or missed diagnoses. (Read the full article)

Active termination of life in newborns with myelomeningocele because of assumed suffering in these newborns has been extensively discussed. However, the level of discomfort and pain in these newborns has never been substantially assessed.

This is the first study presenting quantitative data on discomfort and pain in newborns with myelomeningocele. Therefore, it can be of guidance in the choice of treatment: either active treatment or palliative care in the context of end-of-life decisions. (Read the full article)

Children with special health care needs present clinically with varied functional difficulties across an array of health conditions. Little attention has been given to the interaction of these descriptors at a population level, thereby not addressing the complexity of functional difficulties and their impact on the health of CSHCN.

The data demonstrate the relationships among functional difficulties and health conditions, which then improve our understanding of CSHCN and their needs. Functional difficulties contribute significantly to outcomes, such as emergency room visits, parental work patterns, and limitations in daily activities, and have implications for practice, training, policy, and research.

Strategies to assist patients in achieving optimal chronic disease self-management are critical. The complex family and regimen issues surrounding pediatric type 1 diabetes management suggest the need to integrate such strategies into routine clinical care.

This study demonstrates the efficacy of a practical, low-intensity behavioral intervention delivered during routine care for improving glycemic outcomes. Findings indicate that the approach may offer a potential model for integrating medical and behavioral sciences to improve health care. (Read the full article)

Sleep-disordered breathing is associated with neurobehavioral morbidity in children. Prior related research has generally been cross-sectional or short (ie, 1–2 years) follow-up studies of a single symptom (ie, snoring, obstructive sleep apnea, mouth breathing), with limited control for confounders.

Sleep-disordered breathing was assessed as a trajectory of combined symptoms from 6 months to 69 months, in more than 11 000 children. Sleep-disordered breathing was associated with 40% and 60% more behavioral difficulties at 4 and 7 years, respectively. (Read the full article)

The availability of rapid response systems to assist deteriorating patients is the standard of care in children’s hospitals. Metrics for evaluating their effectiveness include cardiac and respiratory arrest rates, rare events that require years of data to show significant improvements.

A proximate outcome for in-hospital mortality among patients receiving rapid response system assistance was developed. This "critical deterioration" metric was eightfold more common than arrests and demonstrated criterion and construct validity, facilitating meaningful evaluation over shorter periods of time.

Some studies reveal an association between exposure to alcohol consumption in movies and youth drinking, but the evidence is sparse.

Exposure to alcohol consumption in movies is associated with youth binge drinking, is little influenced by cultural differences between countries (Germany, Iceland, Italy, Netherlands, Poland, and Scotland), and is specific to movie alcohol, not movie smoking, depictions. (Read the full article)

Numerous late preterm infants undergo repetitive heel lancing procedures during their first hours of life to evaluate glycemic control. Heel lances are painful and 25% glucose solution is effective on reducing procedural neonatal pain scores and crying behavior.

This noninferiority randomized controlled trial demonstrated that compared with breast milk, 25% glucose provided lower pain scores and reduced duration of cry. Further research is necessary to clarify breast milk’s mechanisms and efficacy on neonatal pain relief. (Read the full article)

Pneumonia is still a significant problem in young children from developing countries where zinc deficiency is prevalent. Although zinc supplementation reduces the risk of childhood pneumonia, the effect of adjunct zinc on severe pneumonia is unclear with conflicting results.

The overall effect, if any, of zinc as adjuvant therapy for World Health Organization–defined severe pneumonia in young children is small. (Read the full article)

Preterm infants are at increased risk of behavioral problems, which has been associated with maternal distress. Paternal psychological well-being is less studied. Parents’ concerns may affect their perceptions or attitudes and have negative effects on the behavior of the child.

Parents report more behavior problems in VLBW children at age 3 if they themselves have had symptoms of depression, parenting stress, or weak sense of coherence. Also, the paternal psychological well-being contributes to the behavioral development of a preterm child. (Read the full article)

Several studies have analyzed fatal or nonfatal youth injury incidence in US agricultural settings, but none have combined those estimates to form an overall picture. The only detailed study of costs related to such injuries is restricted to nonfatal injury.

This study provides a comprehensive analysis of the annual incidence and cost of agricultural youth injuries in the United States. It analyzes them from different perspectives: fatal versus nonfatal, at work versus not at work, and requiring hospitalization versus not requiring hospitalization. (Read the full article)

For children and young people with life-limiting conditions, palliative care services should be available, but few national or local data are available to estimate the burden of these conditions.

The prevalence of life-limiting conditions in children and young people in England was double the previously reported estimates, at 32 per 10 000 population. This identifies a need for specialist pediatric palliative care services. (Read the full article)

There is a perception among clinicians that methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and/or meningitis result in a greater burden of disease than invasive infections attributed to methicillin-susceptible Staphylococcus aureus (MSSA) among very low birth weight (VLBW) infants.

VLBW infants with MRSA and MSSA bacteremia and/or meningitis have equivalent morbidity and mortality. These findings suggest that allocation of resources for prevention and treatment of both MRSA and MSSA infections among VLBW infants should be comparable. (Read the full article)

Previous research on the cost of childhood autism has been restricted primarily to studying direct costs (money outlays) incurred by publicly and privately funded service systems.

This study estimates the economic impact on the family and examines indirect costs to families in the form of parental labor market productivity losses. (Read the full article)

Changes in BMI category appear to be common in young children and are associated with cardiometabolic risk in cross-sectional studies. However, there are few longitudinal studies and little information from multiethnic samples of US middle school children.

Findings demonstrate that shifts in BMI category are common in middle-school-aged children and associated with clinically meaningful changes in cardiometabolic risk factors. Programs to promote decreases in BMI, prevent increases, and moderate risk are indicated. (Read the full article)

Transcutaneous bilirubinometry was originally developed as a potential replacement for invasive blood sampling, but its clinical application is still limited to a screening method for hyperbilirubinemia. Reasons for this limited clinical value may be diverse.

This study provides insight into the reasons for the limited clinical value of transcutaneous bilirubinometry. This aids to both better interpretation of the measured TcB value from a patient and to possible improvement of the clinical value of the technique. (Read the full article)

Survival takes precedence for adolescent patients with cancer and their families. Patients may not discuss their treatments’ potential to damage their reproductive capacity, which has significant psychological late effects in survivorship.

Strong reproductive concerns of adolescents with cancer may not be captured on current health-related quality of life instruments and may be neglected by parents’ unawareness. Parent-proxy reports of adolescent reproductive concerns are not suitable for capturing specific emotions and feelings. (Read the full article)

Insulin is commonly used to treat neonatal hyperglycemia, but there are few data to support its use. Tight glycemic control with insulin improves outcome in diabetic patients, but it is not known whether it is effective in hyperglycemic preterm infants.

Tight glycemic control with insulin in hyperglycemic preterm neonates decreases the rate of linear growth despite increased weight and occipitofrontal head circumference gain and increases the risk of hypoglycemia. Insulin may not be a safe and effective treatment in hyperglycemic preterm neonates. (Read the full article)

In the prerotavirus vaccine era, diarrhea-associated hospitalization and outpatient rates among American Indian and Alaska Native children were higher than those among the general US population. Routine rotavirus vaccination has dramatically decreased rotavirus diarrhea burden in the general US population.

Decreases in diarrhea-associated hospitalization and outpatient rates among American Indian and Alaska Native children in postvaccine years were observed in all Indian Health Service regions, with declines greater in each subsequent year after vaccine introduction. (Read the full article)

Prenatal methamphetamine exposure has been related to deficits in fetal growth, changes in infant neurobehavior, and fine motor deficits, but little is known about its developmental effects on behavior problems in early childhood.

This is the first prospective study to identify behavior problems associated with prenatal methamphetamine exposure. Mood difficulties and acting-out behavior are increased in exposed children by age 3 years. Early identification and intervention may prevent escalation into delinquency and psychopathology.

The survival of extremely low birth weight infants in resource-limited situations is dismal due to limited neonatal intensive care facilities. Nasal continuous positive airway pressure resulted in an increased survival of these infants, but many still require back-up ventilation.

Nasal continuous positive airway pressure and intubation, surfactant, and extubation practiced in a neonatal high care ward with limited resources and limited back-up ventilatory facilities can improve the survival of extremely low birth weight infants. (Read the full article)

Research has highlighted an important relationship between motor coordination and emotional functioning in children and adolescents. Few studies have provided support for this idea; research is therefore needed to further understand the relationship between the motor and emotional domains.

The results suggest that the relationship between motor coordination and emotional functioning (anxious and depressive symptoms) in an adolescent sample may be understood in terms of a mechanism whereby motor coordination has an indirect impact on emotional functioning via self-perceptions.

Healthcare Effectiveness Data and Information Set (HEDIS) measures are widely used to assess the reliability of pediatric immunization delivery. The extent to which these measures provide accurate ("is this child up-to-date on immunizations?") and useful ("is this child due for catch-up immunizations?") information is unclear.

Overall, HEDIS childhood immunization measures are accurate and useful. Users of HEDIS data should be aware, however, that certain immunizations (eg, hepatitis B, pneumococcal conjugate) and children (eg, those with a single overdue immunization) are more prone to HEDIS misclassification.

Emergency contraception is a safe and effective method of pregnancy prevention after unprotected intercourse.

Pharmacies commonly communicate misinformation, both to adolescents and to physicians, concerning who is able to access emergency contraception and through what means. (Read the full article)

Staphylococcus aureus is a leading cause of infections in infants. Staphylococcal colonization is a known risk factor for infection, but whether maternal colonization plays a role in subsequent colonization in the infant is unclear.

This prospective study found that infants born to women colonized with S aureus either during their third trimester of pregnancy or at the time of delivery are more likely to harbor S aureus than are those born to noncolonized women. (Read the full article)

Febrile seizure risk 7 to 10 days after measles-mumps-rubella-varicella (MMRV) is double that of separate measles-mumps-rubella (MMR) and varicella vaccines among 1-year-olds. Whether MMRV or MMR and varicella affect febrile seizure risk among 4- to 6-year-olds has not been reported.

Using Vaccine Safety Datalink data, we examined risk for febrile seizures after measles-containing vaccines. This study provides reassurance that MMRV and separately administered MMR and varicella were not associated with increased risk of febrile seizures among 4- to 6-year-olds. (Read the full article)

Fetus and infants until 3 months of age are unable to metabolize caffeine, which crosses the placenta and in adults has a somnolytic effect. Little is known about the effect of caffeine consumption by pregnant or nursing mothers over infant sleeping.

In this setting where caffeine is largely consumed in pregnancy and by nursing mothers, heavy consumption (≥300 mg/day) did not increase the number of nighttime awakenings by their 3-month-old infants. (Read the full article)

Nearly one-third of all US children are overweight or obese, with even higher prevalence among Mexican American children. Overweight and obesity increase systemic inflammation, contributing to increased risk for chronic diseases, such as type 2 diabetes mellitus and cardiovascular disease.

Obese Mexican American children had concurrent alterations in both inflammatory markers and traditional disease risk markers, relative to healthy weight children. Our results provide evidence partially explaining the health disparity for disease in Mexican American children who are overweight/obese. (Read the full article)

Cancer in a child may affect the quality of the parents’ relationship, but few studies have examined a potential effect on parental divorce, and no studies have accounted for the proportion of couples that live outside formal marriages.

In this nationwide registry-based study with up to 20 years of follow-up, we included both married and cohabiting couples, reflecting modern family structures. We found that experiencing cancer in a child is not a risk factor for the parents separating. (Read the full article)

Complementary and alternative medicine (CAM) use for pediatric asthma is increasing. It is well known that effective asthma management depends on patient adherence to treatment. The authors of previous cross-sectional studies have linked CAM use with decreased adherence to conventional asthma treatment regimens.

This longitudinal data set was unique, allowing us to focus on patients who initiated CAM and to follow subsequent asthma medication adherence. We found that CAM use was not associated with adherence, suggesting that patients may practice CAM alongside conventional therapies. (Read the full article)

Although developmental care in NICUs reduces the stress experienced by preterm infants, the actual level of developmental care may vary and little is known about how the level of developmental care relates to preterm infants’ neurobehavioral performance.

The study demonstrates the relationship between variations in developmental care in NICUs and the neurobehavior of preterm infants. Infants from NICUs with high-quality developmental care compared with infants from units with low quality of care evidenced a better neurobehavioral profile. (Read the full article)

Some but not all randomized trials have shown effects of probiotics on incidence and duration of diarrhea and respiratory tract infections among children in developing countries. Calcium improves resistance to intestinal infections in adults, but efficacy in children is unknown.

Lactobacillus reuteri DSM17938 may prevent diarrhea, especially in children with lower nutritional status. Regular calcium milk, alone or with Lactobacillus casei CRL431, did not reduce diarrhea. None of the interventions affected respiratory tract infections in these Indonesian children. (Read the full article)

Preterm, growth-restricted infants are at high risk of necrotizing enterocolitis (NEC). NEC occurs most frequently in infants who have received enteral feeds. It is common practice to delay introduction of enteral feeds in these infants.

Early introduction of enteral feeds results in earlier achievement of full enteral feeding. Early feeding is not associated with a higher risk of NEC. Delayed feeding is associated with a higher risk of cholestasis. (Read the full article)

Although all residents progressively assume responsibility for clinical skills under the teaching and supervision of attending physicians, senior residents also assume responsibility for teaching and supervising. This leads to a dynamic negotiation of responsibilities, particularly on clinical work rounds.

A better understanding of how attending physicians and senior residents negotiate shared responsibilities for teaching and supervising, and the context in which this negotiation occurs, may clarify assumptions and set expectations for resident training. (Read the full article)

Trisomy 13 and trisomy 18, common chromosomal abnormalities, are generally considered fatal within the first year after birth, although some children live longer. Little is known, however, about the inpatient medical courses of these infants and children.

Evaluation of nationally representative hospitalization data demonstrates that a significant number of children with trisomy 13 and trisomy 18 live beyond 1 year of age and that the care they receive includes both medical and surgical treatments. (Read the full article)

During prenatal counseling for prematurity, information is provided to expectant parents to empower them to participate in the medical-care decision-making regarding their child. However, numerous studies have shown that providing information effectively during preterm labor is challenging.

The current study provides evidence that effectiveness of counseling can be improved by providing written information to parents before the face-to-face verbal counseling. Appropriately presented, detailed information improves knowledge and decreases maternal anxiety. (Read the full article)

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)

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)

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)

Cross-sectional imaging can reduce the negative appendectomy rate (NAR) in children being evaluated for suspected appendicitis; however, the ability of diagnostic imaging to decrease NAR may vary by age and gender.

Cross-sectional imaging leads to a significant reduction in NAR for children younger than 5 years and girls older than 10 years. For boys older than 5 years being evaluated for uncomplicated appendicitis, advanced imaging appears to have limited value. (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)
