Poor health in children is associated with exposure to family violence and disruption. Telomere length has been hypothesized to be a lasting biological indicator of exposure to early adversity and potentially predictive of negative health outcomes throughout the life course.

Telomere length reflects exposure to family violence and disruption and may be an early indicator of the biological impact of early adversity. Children exposed to interpersonal violence and family disruptions had significantly shorter telomeres. Gender moderated these associations. (Read the full article)

Studies on adult patients who have Crohn disease have shown a comparative benefit of anti-TNFα versus placebo and thiopurines. These same studies have not been done in children, because of time, cost, and ethical (withholding an efficacious treatment) challenges.

Anti-TNFα therapy administered in routine practice to children with Crohn disease was more effective than usual care at achieving clinical and corticosteroid-free remission. Using data from the ImproveCareNow learning health system for observational research is feasible and produces valuable evidence. (Read the full article)

Homicide is the third leading cause of mortality in general population youth aged 15 to 29 years. Groups at greatest risk for early violent death (racial/ethnic minorities, males, poor persons, and urban youth) are overrepresented in the juvenile justice system.

We examined rates of and risk factors for firearm homicide and other causes of death in delinquents 16 years after detention. Our study analyzes gender differences; compares Hispanics, African Americans, and non-Hispanic whites; and includes a representative sample of delinquents. (Read the full article)

Caffeine has predictable effects on cardiovascular function in both adults and children. Our previous work has shown that there are gender differences in this cardiovascular response, with boys having a greater change in heart rate and blood pressure than girls.

This study shows that the gender differences in cardiovascular response to caffeine emerge after puberty and there are some differences in postpubertal girls across the menstrual cycle. (Read the full article)

Adverse childhood experiences have been shown to have long-term impacts on health and well-being. However, little work has been done to incorporate the voices of youth in understanding the range of adverse experiences that low-income urban children face.

Study participants cited a broad range of adverse experiences beyond those listed in the initial adverse childhood experience studies. Domains of adverse experiences included family relationships, community stressors, personal victimization, economic hardship, peer relationships, discrimination, school, health, and child welfare/juvenile justice systems.

Previous studies have revealed that children in child care are frequently ill with mild illness and are unnecessarily excluded from child care at high rates.

Parent race/ethnicity, single parents, and work-related concerns are associated with increased emergent/urgent care use for a sick child excluded from child care, even for mild illnesses. (Read the full article)

Children are often evaluated in the emergency department after a concussion. Although prolonged symptoms are associated with higher initial symptom severity when measured 2 to 3 weeks after injury, a similar association with acute symptom severity has not been demonstrated.

Higher acute symptom severity is not associated with development of persistent post-concussion symptoms 1 month after injury, but persistent post-concussive symptoms affect a significant number of children after concussion. Outpatient follow-up is essential to identify children who develop persistent symptoms. (Read the full article)

Autism prevalence is reported to be highest among non-Hispanic white children, lower in Hispanic and African American/black children, and highly variable in Asian/Pacific Islanders. More comorbid intellectual disability and delays in expressive language have been observed among Hispanic and African American children.

Maternal nativity is a risk factor for childhood autism in US populations. We observed higher risk of severe autism phenotypes in children of foreign-born black, Central/South American, Filipino, and Vietnamese mothers and US-born African Americans and Hispanics compared with US-born whites.

Indoor tanning has gained widespread popularity among adolescents and young adults. Incidence rates of early-onset basal cell carcinoma also appear to be rising. Scant evidence exists on the impacts of early exposure and whether it leads to early occurrence of this malignancy.

In a US population-based study, indoor tanning was associated with an elevated risk of basal cell carcinomas occurring at or before the age of 50 years, with an increasing trend in risk with younger age at exposure among adolescents and young adults. (Read the full article)

Neurocognitive deficits, academic delays, and behavioral and emotional problems are well documented in school-age children in relation to socioeconomic disadvantage and residential instability. Despite adversity, early intervention can facilitate healthy cognitive, emotional, and social development.

Homeless youth demonstrated elevated rates of untreated psychiatric disorders, low academic achievement, and impaired neurocognition. Mental health and neurocognitive symptoms were associated with vocational outcome. Intervention beyond employment services alone is needed to improve functioning. (Read the full article)

Mixed results exist regarding the efficacy of caregiver-mediated interventions for children who have ASD. To date, randomized controlled studies have rarely compared 2 active interventions; none have focused on targeting families who are low-resourced in the community.

Significant improvements were found in social communication of children who have autism when caregivers received a hands-on caregiver training intervention in the home. These are the first data from a low-intensity, short-term intervention with low-resourced families. (Read the full article)

Children born late and moderately preterm are at increased risk of developmental problems compared with term-born peers. Screening for developmental problems in the early years may thus aid in the early identification of children at risk for adverse outcomes.

The Parent Report of Children’s Abilities-Revised has good concurrent validity and 90% sensitivity and 76% specificity for identifying moderate/severe cognitive developmental delay in infants born late and moderately preterm. This parent questionnaire may be used as a clinical screening tool. (Read the full article)

Sending and receiving sexually explicit picture and text messages (sexting) is related to sexual activity and risk behavior among some high school populations, yet little is known about sexting associations with sexual activity and risk behavior among middle school students.

This study is the first to examine sexting among a probability sample of middle school students and found that middle school students who text excessively and send and receive sexts are more likely to report being sexually active. (Read the full article)

Early referral of infants with critical congenital heart disease (CCHD) is recommended to reduce mortality. However, few population-based data have been published showing the relationship between CCHD neonatal mortality and timing of cardiac evaluation at a specialty center.

In neonates with CCHD, 35% were not evaluated at a cardiac center by 4 days of age. These cases accounted for a significant number of CCHD deaths. This information enhances the rationale for pulse oximetry screening of neonates for CCHD. (Read the full article)

Available bowel preparation solutions for colonoscopy continue to represent a challenge for children and their families due to poor taste, high volume, and dietary restrictions with subsequent poor compliance and need to place nasogastric tube for administration.

Low-volume polyethylene glycol (PEG) preparations and sodium picosulphate plus magnesium oxide and citric acid (NaPico+MgCit) are noninferior to PEG 4000 with simethicon for bowel preparation before colonoscopy in children. Given its higher tolerability and acceptability profile, NaPico+MgCit should be preferred in children. (Read the full article)

As the number of chronically ill children grows in the United States, end-of-life discussions and advance directives (AD) will become increasingly important. Although pediatric palliative care is gaining interest, little is known about parental preferences regarding ADs for chronically ill children.

Knowledge about ADs is limited among caregivers of children who have chronic illness. However, interest in creating ADs is high, suggesting an unmet need and opportunity for health care providers to improve the care of children who have chronic illness. (Read the full article)

Oral vaccine responses are low in children from less-developed countries perhaps as a result of intestinal dysbiosis. New high-throughput DNA-based methods allow characterization of intestinal microbiota as a predictor of vaccine responses.

High abundance of stool Actinobacteria, including Bifidobacterium, was associated with higher responses to oral and parenteral vaccines and a larger thymus in Bangladeshi infants. Conversely, high abundance of Clostridiales, Enterobacteriales, and Pseudomonadales was associated with neutrophilia and lower vaccine responses. (Read the full article)

Passive or opt-out consent has been successfully used to recruit subjects in several investigational studies. However, institutional review boards are often inconsistent in their application of federal regulations regarding passive consent.

This study documented the variability among 24 local institutional review boards in their application of federal regulations regarding passive consent and parental acceptance of a passive consent strategy in a multicenter pediatric study. (Read the full article)

Immigrant children are more likely to be uninsured versus nonimmigrant children. The extent to which immigrant families are aware of and interested in obtaining insurance is unclear. Obstacles to participation in insurance exchanges and public insurance programs are also unknown.

Barriers for children in immigrant families include awareness of and experience with various health insurance options, perceived costs and benefits of insurance, structural/policy restrictions on eligibility, and the likelihood of working organizations likely to offer employee insurance coverage.

The Centers for Disease Control and Prevention recommends that health departments in all 50 states deliver AFIX (Assessment, Feedback, Incentives, and eXchange) consultations to 25% of federally funded vaccine providers each year. AFIX effectively raises vaccination coverage among young children.

AFIX consultations achieved short-term gains in coverage for 11- to 12-year-olds for vaccines in the adolescent platform. No gains occurred for older adolescents or over the long term. Consultations were equally effective when delivered in-person or by webinar. (Read the full article)

Massachusetts implemented a major health reform in 2006 to reduce uninsurance, improve access to care, and increase financial protection for its citizens, but little is known about its effect on privately and publicly insured children with special health care needs.

Massachusetts health reform improved access to specialists for privately insured children with special health care needs but did not reduce uninsurance, increase access to primary care, or improve financial protection. National reform may produce similarly modest outcomes for these children. (Read the full article)

Socioeconomic status (SES) often influences timeliness of health care delivery, even in publicly funded systems. Children need prompt surgical care for a variety of time-sensitive developmental conditions, and children of lower SES may be especially vulnerable to delays in surgery.

It is unknown whether a publicly funded system’s ability to provide timely pediatric surgical care is related to SES. In 39 327 consecutive surgical cases, we demonstrate that SES need not influence timeliness of surgical care in a publicly funded system. (Read the full article)

Delaying cord clamping beyond 30 to 60 seconds after birth seems beneficial for all infants due to blood transfusion from placenta. Experimental data have demonstrated that ventilation implemented before cord clamping improved cardiovascular stability by increasing pulmonary blood flow.

Healthy self-breathing neonates in a low-resource setting are more likely to die if cord clamping occurs before or immediately after onset of spontaneous respirations. The risk of death/admission decreases by 20% for every 10-second delay in clamping after breathing. (Read the full article)

There is growing support for adopting the milliliter as the standard unit for liquid medication instruction; teaspoon and tablespoon units can be confusing and may endorse kitchen spoon use. There are concerns that parents may not understand milliliter-based instructions.

Parents who used milliliter-only units made fewer dosing errors than those who used teaspoon or tablespoon units. Moving to a milliliter-only standard could reduce confusion and decrease medication errors, especially for parents with low health literacy and non-English speakers. (Read the full article)

Sudden infant death syndrome and other sleep-related causes of infant mortality have several known risk factors. Less is known about the association of those risk factors at different times during infancy.

Risk factors for sleep-related infant deaths may be different for different age groups. The predominant risk factor for younger infants is bed-sharing, whereas rolling to prone, with objects in the sleep area, is the predominant risk factor for older infants. (Read the full article)

Sleep disturbance affects 47% to 60% of children with atopic dermatitis and is a leading cause of impaired quality of life for the patients and their family.

Sleep disturbance in children with atopic dermatitis can be predicted by a Scoring Atopic Dermatitis index of ≥48.7, and lower nocturnal melatonin secretion might play a role in the pathophysiology. (Read the full article)

Children with autism sleep poorly compared with their peers. Sensory integration, including use of weighted blankets, is proposed as a means to reduce arousal and stress. There is, however, no evidence that weighted blankets can improve sleep for these children.

This is the first robust study to evaluate the impact of weighted blankets and show that they do not improve sleep parameters in children with autism spectrum disorder. (Read the full article)

Most therapeutic products used in children have not been studied in that population. There is a need for special incentives and market protection (pediatric exclusivity) to compensate drug sponsors for studying these products in children.

Of 189 products studied under pediatric exclusivity, 173 (92%) received new labeling information. Pediatric efficacy was not established for 78 (42%), including 81% of oncology drugs. Probability of demonstrating efficacy was related to therapeutic area and year exclusivity was granted. (Read the full article)

Obstructive sleep apnea syndrome (OSAS) prevalence in children with sickle cell anemia is not well described. Although these children often experience nocturnal oxygen desaturation, it is unclear whether they are more likely to have OSAS.

Children with sickle cell anemia have a high prevalence of OSAS with typical symptoms, beyond just nocturnal oxyhemoglobin desaturation. This study supports the need for increased efforts to screen for, diagnose, and treat OSAS in this vulnerable population. (Read the full article)

Clamping and cutting of the umbilical cord at birth is the most prevalent of all operations; however, the optimal timing of cord clamping is still a controversial issue, with different timings offering advantages and disadvantages.

Our findings suggest a protective effect of late cord clamping, increasing the antioxidant capacity and decreasing the inflammatory-mediated effects induced during delivery of term neonates. (Read the full article)

Prenatal maternal smoking has been associated with attention-deficit/hyperactivity disorder in children, but the causal nature of this association is unclear. Controlling for the association with paternal smoking has been inconsistent.

Women who used nicotine replacement also had children with a higher risk of attention-deficit/hyperactivity disorder. Mother's smoking behavior appears more important than father's, suggesting a possible causal effect of nicotine exposure or factors related to maternal nicotine dependence. (Read the full article)

Previous studies showed that prevalence of abdominal obesity among US children and adolescents increased significantly between 1988–1994 and 2003–2004. However, little is known about recent time trends in abdominal obesity since 2003–2004.

In 2011–2012, 17.95% of children and adolescents aged 2 to 18 years were abdominally obese defined by waist circumference. The prevalence of abdominal obesity leveled off among US children and adolescents from 2003–2004 to 2011–2012. (Read the full article)

Newborn infants who are predominantly breastfed are much more likely to develop prolonged hyperbilirubinemia than those fed formula, but the prevalence of prolonged hyperbilirubinemia in a largely white, North American, breastfed population is unknown.

Practitioners can be reassured that it is normal for 20% to 30% of predominantly breastfed infants to be jaundiced at age 3 to 4 weeks and for 30% to 40% of these infants to have bilirubin levels ≥5 mg/dL. (Read the full article)

Mothers of children with neurodevelopmental disabilities often experience poor health, high stress, anxiety, and depression. Highly stressed parents are less effective in their parenting roles, risking their children's developmental progress.

Evidence-based interventions in mindfulness and positive psychology significantly reduce distress in mothers of children with disabilities. Well-trained peer-mentors are effective interventionists. Adult-oriented services are needed for these mothers to improve their mental health and sustain their caregiving over the long-term. (Read the full article)

Graduating from high school is associated with better health and health behaviors. However, no rigorous studies have tested whether exposure to a high-performing school improves health or health behaviors, thus the causal relationship is unknown.

Exposure to successful schools can reduce very risky health behaviors among low-income adolescents. The primary mechanism is mostly due to better school retention and also due to better academic achievement. (Read the full article)

Research has shown that HIV-affected children face considerable threats to health and mental health. Few studies have investigated the effects of HIV on the health and well-being of HIV-negative children living with HIV-positive caregivers.

By comparing the prevalence of mental health problems and protective and risk factors among HIV-positive, HIV-affected, and HIV-unaffected children in Rwanda, this study demonstrates that the mental health of HIV-affected children requires policy and programmatic responses comparable to HIV-positive children.

After neonatal extracorporeal membrane oxygenation treatment, children are at risk for neurodevelopmental problems including delayed motor function. So far this has only been studied cross-sectionally until age 7 years.

We describe, in a nationwide evaluation, the longitudinal course of motor function development after neonatal extracorporeal membrane oxygenation with persisting problems up to 12 years. At risk are children with congenital diaphragmatic hernia and those with chronic lung disease. (Read the full article)

Supplemented mother’s own milk is the preferred nutrition for very low birth weight infants.

Through targeted encouragement and guidance, most mothers are able to provide milk to their very low birth weight infants, both for early and prolonged feeding, in an open-bay NICU. (Read the full article)

Pediatricians need to treat overweight in early childhood. Family-based interventions in specialized clinics are efficacious in children age 8 years and older. Data regarding treatment of younger children are limited in specialty clinics and primary care.

This study shows that a 12-month family-based behavioral intervention in primary care is more efficacious compared with Control condition with a child-only focus. Weight outcome differences between Intervention and Control persist in children and parents after a 12-month follow-up. (Read the full article)

Growth failure has been frequently reported in children who have obstructive sleep apnea syndrome (OSAS) owing to adenotonsillar hypertrophy. Adenotonsillectomy (AT) has been reported to accelerate weight gain in children who have OSAS in nonrandomized uncontrolled studies.

This randomized controlled trial of AT for pediatric OSAS demonstrated significantly greater weight increases 7 months after AT in all weight categories. AT normalizes weight in children who have failure to thrive, but increases risk for obesity in overweight children. (Read the full article)

Numerous studies have demonstrated clinical benefits of medical emergency team (MET) implementation, including reductions in mortality, cardiac arrests, and critical deterioration events. No studies have evaluated the financial costs and benefits of METs.

The costs of operating an MET can plausibly be recouped with a modest reduction in critical deterioration events. Hospitals reimbursed with bundled payments could see real financial savings by reducing critical deterioration events with a MET. (Read the full article)

Preterm birth has been associated with increased risk of venous thromboembolism (VTE) in infancy, but the longer-term risk is unknown.

In a large national cohort, low gestational age at birth was associated with increased risk of VTE in infancy, early childhood, and young adulthood. These findings call for better awareness of the long-term risk of VTE among preterm birth survivors. (Read the full article)

Term MRI can assist in identifying the nature and extent of brain injury in preterm infants. However, brain injury detected by MRI does not fully account for neurodevelopmental impairments, particularly cognitive and behavioral impairments, common in preterm survivors.

In addition to brain injury, an assessment of brain growth by using one-dimensional measurements on MRI is helpful for predicting neurodevelopment. Two different patterns of impaired brain growth are observed that relate independently to early cognitive development in preterm infants. (Read the full article)

Delayed diagnosis of critical congenital heart defects (CCHDs) is associated with increased morbidity and mortality.

Despite increasing prenatal diagnosis rates, delayed diagnosis of CCHDs continues to occur, with rates highest among isolated cases and those delivered at nontertiary care hospitals. Better understanding of delayed diagnosis could help to improve screening efforts. (Read the full article)

Neonatal narcotic abstinence syndrome (NAS) has become more prevalent in the United States. There is no strong evidence base for NAS treatment and thus no consensus regarding NAS management, including the best treatment drug or best taper strategy.

This study demonstrates that regardless of the initial treatment opioid chosen, use of a standard treatment protocol with stringent weaning guidelines reduces duration of opioid exposure and length of hospital stay for infants with NAS. (Read the full article)

Practitioners caring for critically ill infants need to acquire competence in insertion of chest tubes for pneumothorax. Ethical and logistic concerns inhibit the use of animals, and there are no realistic simulation models available for neonatal chest tube insertion training.

An inexpensive, nonanimal chest tube insertion model can be easily constructed and used effectively to train interns and residents to improve their knowledge, clinical skills, and comfort levels to perform the chest tube insertion procedure in infants. (Read the full article)

Several studies have revealed an association between cesarean section (CS) and childhood type 1 diabetes. Most of these studies lacked important information on indication for CS and induction of labor. It is unknown whether the reported associations are causal.

Using a cohort of 2.6 million children we found an association between elective CS and type 1 diabetes. The sibling analysis suggested the association is not causal. The findings are crucial evidence to advise women on mode of delivery choice. (Read the full article)

For newborn infants, extreme hyperbilirubinemia (≥24.5 mg/dL) is associated with risk for severe bilirubin encephalopathy. The causal factor of extreme hyperbilirubinemia is often not established. The genotype of Gilbert syndrome, the UGT1A1*28 allele, is considered a potential risk factor.

The UGT1A1*28 allele was not associated with risk for developing extreme hyperbilirubinemia. (Read the full article)

Total serum bilirubin levels ≥30 mg/dL have been labeled as "hazardous." Levels this high are rare, occurring in 3 to 10 per 100 000 births. Few studies have examined etiologies and long-term outcomes in these infants.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a major identifiable cause, but is under-assessed. Chronic, bilirubin-induced neurotoxicity is rare and only occurred in the setting of additional risk factors (prematurity, G6PD deficiency, sepsis) and at levels far above recommended exchange transfusion thresholds. (Read the full article)

XY disorders of sex development have a diverse etiology and often present with atypical genitalia in the newborn period. Sex assignment in those cases in whom this is marked genital ambiguity is a rare, challenging situation that requires multidisciplinary input.

An international registry has shown temporal changes over the last 3 decades in the practice of sex assignment with a greater proportion of severely affected infants being raised as boys, raising the need for long-term monitoring of these children. (Read the full article)
