To date, 4 small to moderate sized studies have revealed conflicting results on the clinically important question whether thrombocytopenia contributes to persistent patent ductus arteriosus (PDA) in very immature, preterm infants.

Thrombocytopenia in the first 24 hours after birth was not associated with the incidence of PDA at postnatal day of life 4 to 5 in a large cohort of preterm infants with <1500 g birth weight. Platelet dysfunction, rather than platelet number, might play a role in ductus arteriosus patency. (Read the full article)

Neonatal sepsis is an important cause of under-5 childhood mortality. Infants born to HIV-infected mothers are at increased risk of morbidity and mortality, even if not having acquired HIV. This association needs further study during the neonatal period.

Maternal HIV infection was associated with increased vaginal colonization by Escherichia ecoli but not group B Streptococcus. Neonates born to HIV-infected mothers were only at increased risk of sepsis if they had acquired HIV-infection, but not if HIV-uninfected. (Read the full article)

There is evidence from both developed and developing countries that antiretroviral treatment significantly reduces mortality in HIV-infected children. However, in sub-Saharan Africa, numerous health system, financial, and human resource obstacles make delivering quality pediatric HIV care a challenge.

We describe the experience of the Baylor International Pediatrics AIDS Initiative in Malawi, Lesotho, and Swaziland. Despite challenges delivering pediatric treatment in these countries, mortality and clinical outcomes approaching those from developed countries are feasible. (Read the full article)

Materialism and life satisfaction are known to be associated with each other. Research among adults has shown that materialism and life satisfaction negatively affect each other, leading to a downward spiral.

In contrast to research conducted among adults, no longitudinal effect of materialism on life satisfaction was found for 8- to 11-year-olds. However, life satisfaction did negatively affect materialism, but only for children who were frequently exposed to advertising. (Read the full article)

Birth defects are associated with preterm birth and are a major contributor to infant mortality. There are persistent black-white differences in overall infant mortality and infant mortality attributable to birth defects.

Among infants delivered at 37 to 44 weeks, blacks and Hispanics had significantly higher neonatal and postneonatal mortality attributable to birth defects than whites. Among infants delivered at 20 to 33 or 34 to 36 weeks, neonatal mortality attributable to birth defects was significantly lower among blacks. (Read the full article)

Early life nutrition may program pubertal timing. Limited evidence suggests breastfeeding is associated with later puberty and childhood milk consumption with earlier puberty; whether these observations are biologically mediated or confounded by socioeconomic position is unclear.

In a developed non-Western setting with little socioeconomic patterning of pubertal timing, neither breastfeeding nor childhood milk consumption was associated with pubertal timing, suggesting nutritional exposures during potentially critical periods may not have long-term effects on rates of maturation.

Systematic screening for child abuse of all children presenting at emergency departments might increase the detection rate of child abuse but studies to support this proposal are scarce.

Systematic screening for child abuse in emergency departments is effective in increasing the detection of suspected child abuse. Training emergency department staff and requiring screening legally at emergency departments increase the extent of screening. (Read the full article)

Evaluation of neonatal surgical outcomes is necessary to guide improvements in the quality of care. Meaningful comparisons must adjust for factors that alter outcomes independent of the surgical procedures.

Herein is described a method that permits risk adjustment for the broad range of noncardiac neonatal surgery, regardless of gestational age, to permit useful comparisons for quality improvement. (Read the full article)

Sleep disordered breathing (SDB) and behavioral sleep problems (BSPs) affect cognitive, behavioral, and language development. No studies have examined associations between SDB and BSPs across early childhood, and later special education need (SEN), on a population basis.

A history of SDB through 5 years of age was associated with ~40% increased odds of SEN at 8 years, among >11 000 children. BSPs were associated with 7% increased odds of SEN, for each additional ~12 months of reported BSPs. (Read the full article)

Little is known about how communication during pediatric asthma visits is associated with child control medication adherence 1 month after the visit.

When providers asked for caregiver input into the asthma treatment plan during the visit, caregivers reported significantly higher child medication adherence to control medications 1 month later. (Read the full article)

Previous studies suggest that abnormal findings on conventional EEG during the neonatal period are associated with death or severe brain injury in preterm infants. However, large cohort studies on preterm EEG for predicting later neurodevelopmental outcome remain scarce.

This study demonstrates precise prognostic values of conventional EEG for predicting neurodevelopmental outcome in the current perinatal care setting. Additionally, its prognostic values are independent of severe injury on neuroimaging and clinical risk factors. (Read the full article)

Risk of preterm birth (PTB) has been noted to be higher for newborns with congenital heart defects (CHDs). The role of associated anomalies, whether PTB is spontaneous or medically induced, or specific categories of CHDs have not been elucidated.

By using population-based data, we found that PTB associated with CHDs was due to spontaneous PTB. Associated anomalies accounted for a small part of this increase, and there were specific associations between categories of CHDs and PTB. (Read the full article)

The relationship between energy intake and obesity in children has yielded inconsistent results. Efforts to improve dietary intake as a means of improving weight status have largely yielded disappointing results.

Self-reported energy intake for younger, but not older, overweight/obese children is higher than healthy-weight peers. In early childhood, higher (or excessive) energy intake may lead to onset of obesity, but other mechanisms may be important to maintain obesity through adolescence. (Read the full article)

Pediatric osteoarticular infections can be treated with successful microbiologic and clinical outcomes with a transition from parenteral to oral therapy. The best way to determine the timing of this transition is neither well studied nor standardized.

A total of 193 (99.5%) of 194 pediatric patients with acute bacterial osteoarticular infections were successfully transitioned to oral therapy, determined by using a combination of clinical findings and C-reactive protein levels, representing the largest single-center data set analyzed.

Mortality of very low birth weight infants varies widely between regions and countries; however, the variation in morbidities after adjusting for confounders has not been adequately studied.

Composite outcome of mortality or short-term morbidity for very low birth weight infants was lower in Japan than in Canada. However, marked variations in mortality and individual morbidity exist, revealing areas for improvement in each country. (Read the full article)

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)

The American Academy of Pediatrics and National Heart, Lung, and Blood Institute recommend routine blood pressure measurement in children. Little is known about the frequency with which blood pressure is currently measured in ambulatory pediatric settings in the United States.

Between 2000 and 2009, providers measured blood pressure during only one-third of ambulatory pediatric visits and two-thirds of pediatric preventive visits. The current rate of screening is especially low for children aged 3 to 7 years. (Read the full article)

Expedited partner therapy (EPT) is an effective method of partner treatment of sexually transmitted infections but is not used frequently. There are limited data on provider knowledge, practices, and comfort with EPT use in adolescents.

California pediatric residents have knowledge gaps and discomfort providing EPT and presence of an adolescent medicine fellowship is associated with increased EPT knowledge, use, and comfort among residents. Our findings support the need to improve EPT education in pediatric residencies. (Read the full article)

Most studies on corticoid treatment of respiratory syncytial virus (RSV) respiratory diseases have revealed no beneficial effect. The mechanism by which RSV respiratory-infected patients are insensitive to the antiinflammatory effect of corticosteroids is unknown.

This study helps to understand how a respiratory syncytial viral infection may alter the normal antiinflammatory response to cortisol and the insensitivity to glucocorticoid treatment. The increase expression of β glucocorticoid receptor could be a marker of disease severity. (Read the full article)

Inflammatory bowel disease pathogenesis is incompletely understood. Previous pediatric studies suggested associations between antibiotic use and inflammatory bowel disease development but were limited by recall bias, lack of controls, incomplete antibiotic capture, or included exposures between symptom onset and diagnosis.

Our population-based cohort study suggests that certain childhood antibiotic exposures are associated with an increased risk of developing inflammatory bowel disease. Our findings have implications for understanding the condition’s pathogenesis and provide additional stimulus for reducing unnecessary childhood antibiotic use. (Read the full article)

Understanding human disease genomics requires large population-based studies. There is lack of standardization, as well as social and ethical concerns surrounding the consent process for pediatric participation in a biorepository.

The study identifies specific barriers to pediatric participation in biorepositories relative to adults, and proposes strategies to improve ethical and responsible participation of pediatric-aged patients in large-scale genomics and biorepository-driven research without significantly increasing research burden for affected families. (Read the full article)

Increased computed tomography (CT) use among adults and children presenting to emergency departments has spawned concern about associated radiation exposure. The risks and benefits of CT use for certain conditions, such as abdominal pain, among general pediatric populations remains unclear.

This study analyzes emergency department radiology trends between 1998 and 2008 among children with abdominal pain, highlighting a dramatic increase in CT use. Factors associated with CT ordering include older age, non-black race, and hospital admission. (Read the full article)

School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a widely used universal prevention strategy currently implemented in >16 000 schools across the United States. Previous research has shown positive effects on school climate and school-level discipline problems.

This study reports multilevel results on data from a 4-year randomized controlled effectiveness trial of SWPBIS in 37 elementary schools. Results indicate significant impacts on children’s aggressive behavior problems, concentration problems, office discipline referrals, emotion regulation, and prosocial behavior.

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)

Heart rate continues to be the single most important indicator of well-being in a newborn. Availability of a reliable method to determine heart rate in the first minute would help determine resuscitation interventions, particularly for the extremely premature infant.

Electrocardiograms can provide a reliable, continuous heart rate in the most premature infants in the first minute of resuscitation compared with pulse oximeters. (Read the full article)

Previous studies have found variable child care provider compliance with American Academy of Pediatrics child care illness exclusion guidelines and high rates of unnecessary exclusion of mildly ill children from child care.

Our study is the first to compare child care directors’ return-to-child care practices before the release of the new American Academy of Pediatrics return-to-child care guidelines and to describe the guidelines’ impact if actively adopted by child care providers. (Read the full article)

Previous studies have revealed misconceptions among pediatric patients, their families, and athletic coaches surrounding concussion. Little is known about pediatric primary care and emergency medicine providers’ attitudes and beliefs about diagnosis and management of this mild traumatic brain injury.

Although pediatric primary care and emergency medicine providers regularly care for concussion patients and value their role in management, they may not have adequate training or infrastructure to systematically diagnose and manage these patients. (Read the full article)

With increasing survival rates, there is growing interest in long-term quality of life among patients with univentricular heart defects, and neurodevelopmental deficits play a major role in adverse outcome.

Although median cognitive performance was within normal limits, major neurodevelopmental impairment was found in one-fourth, and minor neurologic dysfunction in almost half of patients. Brain MRI showed mostly ischemic findings of different degrees in the majority of patients. (Read the full article)

The impact of relative age at school entry on academic progress and the risk of being diagnosed with ADHD remains controversial. Stimulants are widely used as a therapeutic option for ADHD in the United States and increasingly in Europe.

Relative age among classmates affects academic performance among boys and girls into puberty, as well as children’s risk of being prescribed stimulants for ADHD. This should be taken into account when evaluating children’s performance and behavior in school to prevent unnecessary stimulant prescribing. (Read the full article)

Physical inactivity is one of the major modifiable factors contributing to the growing national epidemic of childhood obesity. There is lack of literature on pedometer-determined physical activity (PA) during the school day in US minority kindergarten and first-grade students.

This is the first study to assess school-day PA in US urban minority kindergarten and first-grade students. Higher grade level, participation in physical education class, and outdoor recess were found to be independent predictors of PA. (Read the full article)

Youth exposure to retail tobacco advertisements and displays is associated with smoking initiation. The Family Smoking Prevention and Tobacco Control Act of 2009 gives states and local governments legal authority to regulate the time, place, and manner of tobacco advertising.

This is the first experimental study using a virtual store environment to provide evidence that a policy banning tobacco product displays at the point of sale may deter youth from attempting to purchase tobacco products at retail stores. (Read the full article)

Knowledge is limited regarding the epidemiology of persistent pulmonary hypertension of the newborn (PPHN). Previous work has implicated a host of perinatal risk factors and a few antenatal antecedents of PPHN, including maternal consumption during pregnancy of nonsteroidal antiinflammatory medications.

In contrast to results of previous studies, we found no association between PPHN and maternal consumption during late pregnancy of nonsteroidal antiinflammatory drugs in general or ibuprofen in particular. (Read the full article)

Very low birth weight (VLBW; <1500 g) subjects show lower scores in performance-based tests of executive functioning (EF) than control subjects up to young adulthood.

VLBW adults’ perceptions of their EF in everyday life are very similar to those of term-born adults. Parental evaluation of VLBW/small-for-gestational-age adults’ EF is more negative than adults’ self-reports. (Read the full article)

Obesity is a risk factor for failure to initiate breastfeeding, formula supplementation, and short breastfeeding duration. There is a need for interventions that can improve the breastfeeding outcomes of overweight and obese women.

Breastfeeding peer counseling targeting overweight/obese women did not affect exclusive breastfeeding rates or breastfeeding continuation beyond 2 weeks. However, the intervention was associated with improvements in early breastfeeding intensity and fewer infant hospitalizations in the first 6 months after birth. (Read the full article)

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)

Maternal obesity is an increasingly important public health concern and may adversely affect central nervous system development in offspring. However, few studies have explored the relationship between maternal prepregnancy BMI and neurodevelopmental outcomes in children, with conflicting results.

Using data from a large and contemporary UK birth cohort, we found that maternal prepregnancy BMI is negatively associated with children’s cognitive performance. The relationship appears to become stronger as children get older, although the overall effect size is modest. (Read the full article)

Children with congenital heart disease (CHD) are at increased risk for poor growth. Several factors may play a role in poor growth, including feeding difficulties, increased caloric requirements, and the effects of cardiac lesions on growth regulation.

In children with CHD, impaired growth as measured by weight, length, and head circumference occurs simultaneously rather than sequentially, supporting the theory that altered growth regulation likely plays an important role in the poor growth of children with CHD. (Read the full article)

There is evidence that Kingella kingae, the major bacterial cause of osteoarticular infection in children <4 years of age, first colonizes the oropharynx before penetrating the bloodstream and invading distant organs. Diagnosis remains challenging because clinical findings at admission may be normal.

Our study demonstrated for the first time that a simple technique of detecting of K kingae DNA in the oropharynx can provide strong evidence that this microorganism is responsible for the OAI, or even stronger evidence that it is not. (Read the full article)

Socioeconomic status (SES) is inversely related to mortality and health in children; the higher an individual’s SES, the less likely illness and death. It is unknown whether the association of SES and pediatric mortality exists in the inpatient setting.

Within children’s hospitals, in-hospital mortality is inversely associated with SES, but is lower than expected for even the lowest SES quartile. The association between SES and mortality varies by clinical service line. (Read the full article)

Part C early intervention serves ~2.8% of US children who are younger than 3 years old; however, there is evidence that substantial numbers of infants and toddlers with developmental delays receive no early intervention services.

Broad eligibility criteria can classify children who have no delays or minimal delays as candidates for Part C services. Despite this, no jurisdiction provides Part C services to all children who have substantial delays. (Read the full article)

Lifestyle and vulnerability associated with food allergy might predispose affected children to being bullied. Our previous parent survey identified high rates of bullying in this population, but child reports and emotional impact were not assessed.

Bullying was common, often involving threats with food. Bullied food-allergic children, compared with nonbullied, report higher anxiety and lower quality of life. Parental awareness of bullying (~50% of cases) was associated with better social and emotional functioning in the child. (Read the full article)

Children born at very low birth weights have significant catch-up weight gain but differences in height remain. Their BMI, however, tends not to be higher than expected. Data are lacking regarding representative cohorts, defined by gestation and compared with contemporaneous controls.

In a geographic cohort of extremely preterm participants followed until age 18, compared with term controls, weight differences diminish over time, and height differences persist. BMI at age 18 is similar. Height at age 2 is a better predictor of final height than midparental height. (Read the full article)

Birth asphyxia, or failure to initiate or sustain spontaneous breathing at birth, contributes to ~27% to 30% of neonatal deaths in resource-limited countries, including Tanzania. Without change, these countries will fail to meet Millennium Development Goal 4 targets by 2015.

The Helping Babies Breathe program was implemented in 8 hospitals in Tanzania in 2009. It has been associated with a sustained 47% reduction in early neonatal mortality within 24 hours and a 24% reduction in fresh stillbirths after 2 years. (Read the full article)

Prevalence of hypertension in children increased significantly over the past few decades, tracks into adulthood, and is a major risk factor for cardiovascular disease. However, current prevalence estimates in children have largely been based on studies conducted in school environments.

The current study reports the prevalence of childhood hypertension in community pediatric practice, which provides a typical pediatric examination environment, unlike blood pressure measured in school. The results show a significantly lower prevalence than what has previously been reported. (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.

The presence of elevated cardiometabolic risk factors, such as obesity, high glucose or lipid levels, and smoking, in adolescents has been shown to be associated with earlier onset of chronic conditions, such as diabetes and heart disease.

Obesity, smoking, and elevated glucose increases the risk of dying before the age of 55 years. This is the first study to focus on risk factors and mortality among adolescents and young adults in a nationally representative US sample. (Read the full article)

Children with Lyme and septic arthritis of the knee may present similarly, although septic arthritis requires prompt treatment initiation to avoid joint destruction. Clinicians must make initial management decisions without Lyme serology and bacterial culture results.

Our clinical prediction rule accurately identified patients at low risk for septic arthritis in a Lyme disease–endemic area. In the appropriate clinical context, low-risk patients may be spared invasive testing such as diagnostic arthrocentesis. (Read the full article)

The Supplemental Nutrition Assistance Program (SNAP) is the largest federal nutrition assistance program. Studies among adults suggest that SNAP participation may be associated with suboptimal diets. Few studies have extensively examined these associations among children.

SNAP participation was not associated with childhood obesity. SNAP children consumed diets poorer in some aspects than nonparticipants, but intake of some micronutrients was higher. The diets of both groups of low-income children were far from meeting dietary guidelines. (Read the full article)

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

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

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

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