Studies have shown that reciprocal vocalizations between mother and infant have positive effects on language development. It has been shown that girls acquire vocabulary and language skills earlier than boys.

Mothers more readily respond to their infant’s vocal cues than fathers, and infants show a preferential vocal response to their mothers in the first months of life. Mothers respond preferentially to infant girls versus boys at birth and 44 weeks. (Read the full article)

In developed countries, child health disparities across wealth gradients are commonly widening; at the same time, child mortality in low- and middle-income countries is declining. Whether these declines are associated with widening or narrowing disparities is unknown.

A systematic analysis of the evidence on child mortality gradients by wealth in less-developed countries shows that mortality is declining fastest among the poorest in most countries, leading to declining disparities in this important indicator of child health. (Read the full article)

Previous studies have examined state regulations for child care facilities and found substantial variation among states. None of these studies examined regulations related to healthy sleep practices, which is an important and often overlooked intervention target for obesity prevention.

We reviewed state regulations related to healthy sleep in child care and compared them to recent national recommendations put forth by the Institute of Medicine. We found that many states lacked regulations, highlighting an important and timely opportunity for improvement. (Read the full article)

National adolescent vaccination coverage estimates in 2013 among 13- to 17-year-olds are 86% for Tdap vaccine and 78% for MCV4. Comparatively, coverage with ≥3 doses of HPV vaccine is 38% among girls and 14% among boys.

One-fourth of 11-year-olds had HPV vaccine co-administered with Tdap vaccine, compared with two-thirds who had MCV4 co-administered. Whereas by age 17 years, >92% received Tdap vaccine and MCV4, only half of girls and one-fifth of boys completed HPV vaccination. (Read the full article)

Obesity among youth can have immediate health effects as well as longer-term consequences during adulthood. Overweight/obese children and adolescents are much more likely than normal-weight children to become overweight/obese adults.

This large, multisite longitudinal study examines patterns of exit from and entry into obesity between childhood and adolescence. Socioeconomic factors, body image, television habits, and parental obesity were important predictors of whether children remained obese or became obese. (Read the full article)

Pneumococcal conjugated vaccines (PCVs) are known to decrease invasive pneumococcal disease in children, but their effect on pneumonia necessitating hospitalization is more variable across study sites, and effects on hospitalization for sinusitis have not been shown previously.

There was a significant decrease in hospitalizations for sinusitis in children <2 years of age, and hospitalization for pneumonia decreased in children aged <5 years after sequential introduction of PCV7 and PCV13. (Read the full article)

A previous study suggested that physicians in 1 practice network were less likely to diagnose otitis media (OM) and to prescribe broad-spectrum antibiotics for OM for black versus nonblack children.

Nationally, black children with OM are more likely to receive guideline-recommended, narrow-spectrum antibiotics than nonblack children. These findings may reflect inappropriate treatment of OM with the use of broad-spectrum antibiotics in a majority of US children. (Read the full article)

Children who suffer abusive head trauma (AHT) have lasting health and development problems. AHT can reduce life expectancy dramatically. AHT’s contribution to the burden of disease has been estimated only as part of a broad category of intentional injury.

The DALY burden of a severe AHT case averages 80% of the burden of death, with most survivors dying before age 21 years. Even mild AHT is extremely serious, with lasting sequelae that exceed the DALY burden of a severe burn. (Read the full article)

Cyber dating abuse victimization has been correlated with physical, sexual, and psychological adolescent relationship abuse.

This is the first clinic-based study of cyber dating abuse. Forty-one percent of youth reported cyber dating abuse victimization, female more than male respondents. Compared with nonexposed youth, abuse victims reported more sexual assault; female victims reported more contraceptive nonuse and reproductive coercion. (Read the full article)

Pediatric Brain Injury Research Network investigators recently derived a highly sensitive clinical prediction rule for pediatric abusive head trauma (AHT).

The performance of this AHT screening tool has been validated. Four clinical variables, readily available at the time of admission, detect pediatric AHT with high sensitivity in intensive care settings. (Read the full article)

Lead is an ubiquitous environmental pollutant, and no safe threshold for blood lead level in children has been discovered yet. Prenatal lead exposure affects growth of children.

Low level of prenatal lead exposure of <5.0 μg/dL affects postnatal children’s growth, which was further intensified by low calcium intake. (Read the full article)

Primary ciliary dyskinesia presents in infancy with unexplained neonatal respiratory distress, yet diagnosis is often delayed until late childhood. Earlier diagnosis facilitates earlier onset of therapy, which may help to reduce long-term pulmonary morbidity and mortality.

A diagnostic workup for primary ciliary dyskinesia should be considered in a term infant presenting with unexplained respiratory distress and either lobar collapse, situs inversus, or a prolonged oxygen therapy requirement (>2 days). (Read the full article)

There is variability in cerebral palsy prevalence estimates in low-resource countries, related to definitions, detection of milder cases, diagnosis age, and adequate training for clinicians. Thus, differences in prevalence and motor patterns between high- and low-resource countries remain unclear.

There were more children with dystonia and less with spasticity in Bangladesh compared with Australia (cerebral palsy diagnosis/motor classifications were consistent between settings). Differences in motor patterns between high- and low-resource countries have profound implications for early detection and appropriate interventions. (Read the full article)

IP-10 is a novel immunologic marker for tuberculosis (TB) infection. It has been suggested that IP-10 may perform better in children compared with the QuantiFERON test, but only a few studies have investigated IP-10 for diagnosing active TB in children.

This study is the first to investigate IP-10 and QuantiFERON for diagnosing TB in children by using consensus classifications. Both IP-10 and QuantiFERON exhibited poor performance in children from a high-burden setting, and performance was especially compromised in young children. (Read the full article)

The incidence of cerebral palsy is dependent on the gestational age in very preterm infants and risk factors have been identified for term infants. The risk has also proved to be greater among late preterm births compared with term.

The incidence of cerebral palsy was 24-fold in moderately preterm and 6-fold in late preterm infants compared with full-term infants. The most prominent risk factors included asphyxia and intracranial hemorrhage. The incidence diminished over time and with increasing gestational age. (Read the full article)

Infants with Prader-Willi syndrome suffer from hypotonia, muscle weakness, and motor developmental delay and have increased fat mass combined with decreased muscle mass. Growth hormone improves body composition and motor development.

Ultrasound scans confirmed decreased muscle thickness in infants with Prader-Willi syndrome, which improved as result of growth hormone treatment. Muscle thickness was correlated to muscle strength and motor performance. Catch-up growth in muscle thickness was related to muscle use independent of growth hormone. (Read the full article)

Fathers’ attitude and support affects breastfeeding outcomes. Fathers are currently not targeted in breastfeeding support and care provided by health care professionals. Breastfeeding interventions delivered to fathers have been shown to increase breastfeeding exclusivity and duration.

A coparenting breastfeeding support intervention delivered to mothers and fathers in the postpartum period showed beneficial effects on breastfeeding duration, paternal breastfeeding confidence, breastfeeding help provided by fathers, and mothers’ satisfaction with fathers’ involvement with breastfeeding. (Read the full article)

Exclusively breastfed newborns lose weight daily in the first few days after birth. The amount of weight lost varies substantially between newborns, with higher amounts of weight loss increasing risk for morbidity.

This study presents nomograms demonstrating percentiles for weight loss by delivery mode for those who are exclusively breastfed. The nomograms have potential to be used for early identification of neonates on a trajectory for greater weight loss and related morbidities. (Read the full article)

White matter abnormality (WMA) on neuroimaging is considered a crucial link with adverse neurodevelopmental outcome in preterm infants. Brain MRI is more sensitive in detecting WMA than cranial ultrasound (CUS), but questions remain about timing and prognostic value of modalities.

Near-term CUS and MRI abnormalities were associated with adverse 18- to 22-month outcomes, independent of early CUS and other factors, underscoring the relative prognostic value of later neuroimaging in this large, extremely preterm cohort surviving to near-term. (Read the full article)

Cesarean delivery has previously been associated with increased risk of specific immune diseases in children. The mechanism remains unknown.

In 1 large population-based cohort, we demonstrate cesarean delivery as a shared risk factor for several immune-related diseases. Such common risk factor suggests early life commonality in the origins of these chronic immune disorders. (Read the full article)

Respiratory syncytial virus (RSV) infection is a common cause of pediatric hospitalizations. Mortality rates associated with RSV hospitalizations are based on estimates from studies conducted decades ago. Accurate understanding of mortality is required for identifying high-risk infants and children.

Mortality associated with RSV is uncommon in the 21st century, with annual deaths far lower than previous estimates. The majority of deaths occurred in infants with complex chronic conditions or in those with life-threatening conditions in addition to RSV infection. (Read the full article)

Antibiotic overuse is common and is a major public health threat. The prevalence of antimicrobial stewardship programs in children’s hospitals is growing. Single-center studies reveal that antimicrobial stewardship programs are effective in reducing unnecessary antibiotic use. Multicenter evaluations are needed.

Antibiotic use is declining overall across a large network of freestanding children’s hospitals. Hospitals with formalized antimicrobial stewardship programs experienced greater reductions in antibiotic use than other hospitals, suggesting that these interventions are an effective strategy to address antibiotic overuse.

Germ cell tumors in children are heterogeneous and rare neoplasms that occur in various locations, such as gonads, the central nervous system, and the pelvis. The incidence rate has been increasing in some countries.

Population-based analyses of germ cell tumors in children are rare. This population-based study describes the incidence rates, trends, and survival of germ cell tumors in German children from 1987 to 2011. (Read the full article)

Syndrome-specific standardized growth curves are not currently available for non–growth hormone–treated subjects with Prader-Willi syndrome and are required for monitoring growth and development in this rare obesity-related disorder.

Standardized growth curves were useful in monitoring growth and development in these subjects with Prader-Willi syndrome and for the management of growth hormone treatment of both genders, particularly those aged 3 to 18 years. (Read the full article)

Necrotizing enterocolitis is associated with high mortality and morbidity in premature infants. Anaerobic antimicrobial therapy has been associated with increased risk of intestinal strictures in a small randomized trial. Optimal antimicrobial therapy for necrotizing enterocolitis is unknown.

Anaerobic antimicrobial therapy was associated with increased risk of stricture formation. Infants with surgical necrotizing enterocolitis treated with anaerobic antimicrobial therapy had lower mortality. For infants with medical necrotizing enterocolitis, there was no added benefit associated with anaerobic antimicrobial therapy. (Read the full article)

Early diagnosis of LOS in preterm infants may be challenging because of the questionable accuracy of blood culture and the common markers of infections, such as C-reactive protein and procalcitonin.

Our study demonstrated for the first time that P-SEP is an accurate biomarker for the diagnosis of LOS in preterm infants and might contribute to the monitoring of infant response to therapeutic interventions. (Read the full article)

Children and adolescents with attention-deficit/hyperactivity disorder are prone to sustaining trauma that requires emergency department (ED) admission. Methylphenidate can reduce attention-deficit/hyperactivity disorder symptoms and thus theoretically may reduce the risk of trauma-related ED admission, but previous studies did not provide a clear association.

For patients treated with methylphenidate, on-medication periods were associated with lower rates of trauma-related ED admission compared with off-medication periods. A similar protective association was found in both genders. Potential treatment benefit was greater for age ≥16 years. (Read the full article)

Family engagement in the care of hospitalized children may improve outcomes, including medication safety. Although family-centered rounds (FCRs) provide a venue for family engagement in care, how families use this venue to influence medication-related topics is unknown.

Most families initiated medication-related dialogue during FCRs, discussing inpatient and home medications. Topics raised were important for medication adherence and safety, even altering treatment plans. Findings suggest specific medication topics that health care team members can anticipate addressing during FCR. (Read the full article)

Prenatal alcohol exposure can cause congenital neuropsychological and behavioral disabilities in later life. These usually lead to secondary disabilities (adverse outcome when the individual interacts with environmental settings), such as problems with school, the law, alcohol, or drugs.

This was a 30-year psychosocial register–based follow-up on adults with fetal alcohol syndrome and state care comparison group. The FAS-group had lower education and higher rates of unemployment, social welfare, and mental health problems than peers. Rates of criminality did not differ. (Read the full article)

American Public Health Association reported >3.2 million students in the United States are bullied each year; 160 000 students skip school every day for fear of bullying. Little is known about whether bullying affects health-related quality of life (HRQOL) among college students.

Different types of bullying experiences affected different domains of HRQOL. Precollege bullying had long-term effects on HRQOL. Verbal/relational bullying-victimization experiences, mediated via depression, affected psychological HRQOL. Findings inform preventive and clinical practice to ameliorate the impact of bullying.

Many population-based studies including pubertal children are based on self-assessment of pubertal maturation, the reliability of which is uncertain.

Self-assessment is not reliable for precise pubertal staging. Simple distinctions between prepuberty and puberty showed moderate agreement with clinical examinations. Parents and girls tended to underestimate and boys to overestimate pubertal development by up to 50% and 30%, respectively. (Read the full article)

Maternal depression has been associated with adolescent engagement in risky behaviors such as substance use. However, there is a lack of longitudinal research examining timing-specific effects in this relationship.

The results of this study indicate that youth exposed to increasing levels of maternal depressive symptoms in middle childhood are more likely to engage in substance use and delinquent behaviors and have an earlier debut age of these behaviors. (Read the full article)

Fasting insulin levels in childhood are increasingly being used as a surrogate for insulin resistance and risk of later type 2 diabetes, despite only a moderate correlation with whole-body insulin sensitivity and few data related to adult outcomes.

Elevated insulin values between the ages of 3 and 6 years are associated with an elevated risk for later type 2 diabetes. In 9- to 18-year-olds, elevated BMI (but not insulin values) is associated with later type 2 diabetes. (Read the full article)

There is extensive literature documenting that children experiencing foster care placement have myriad adverse developmental outcomes, including poor academic achievement. However, such children face a host of other risk factors that may jeopardize healthy development independent of foster care placement.

Using statewide administrative data from Wisconsin, we observed children before, during, and after foster care placement and compared their educational outcomes with those of the general population, as well as with children more similar in terms of unobserved characteristics.

Influenza vaccine coverage is low, and young children in need of 2 doses in a given season are at particular risk, with less than half receiving both doses. Text message vaccine reminders increase receipt of first dose of influenza vaccine.

Little is known about what types of text message reminders are most effective, including embedding educational information. We demonstrate that text message reminders increase timely receipt of the second dose of influenza vaccine and embedding health literacy information improves effectiveness. (Read the full article)

Frequency of influenza vaccination is low, partially because of missed opportunities to vaccinate. Barriers to implementing successful influenza vaccination reminders in the electronic health record include alert fatigue and incomplete vaccination information due to scattered records.

A noninterruptive, immunization information system–linked influenza vaccination reminder can increase vaccination late in the winter when fewer vaccine doses are usually administered. Tailoring the reminder to clinicians’ needs can increase its use. (Read the full article)

In 2009, only 58% of pediatricians were using electronic health records (EHRs), most of which were lacking pediatric functionality. The American Recovery and Reinvestment Act (ARRA) of 2009 accelerated the implementation of EHRs in pediatric offices.

The effects of ARRA have remained largely unmeasured in pediatrics. This study provides information on the prevalence and functionalities of EHRs, as well as physicians’ perceptions. (Read the full article)

Inadequate sleep has been identified as a risk factor for obesity and other outcomes. Screen time and the presence of a television in the bedroom have been associated with inadequate sleep, but little is known about small screens (eg, smartphones).

Among 2048 fourth- and seventh-graders, children who slept near a small screen reported shorter sleep durations and perceived insufficient rest or sleep. Presence of a television in the bedroom and more screen time were also associated with poorer sleep. (Read the full article)

Expert consensus recommends rest after concussion with stepwise return to activity. Animal and retrospective human data suggest that early mental and physical activity may worsen outcome. There are no pediatric studies testing the efficacy of recommending strict rest after concussion.

Recommending strict rest postinjury did not improve outcome and may have contributed to increased symptom reporting. Usual care (rest for 1–2 days with stepwise return to activity) is currently the best discharge strategy for pediatric mild traumatic brain injury/concussion. (Read the full article)

Parental depression is associated with adverse child outcomes. It is important to understand possible mediators and moderators. Several studies suggest that the family environment or parenting style may be potential pathways for transmission of risk from parents to children.

Paternal depression appears to exert its influence on children’s outcomes through an effect on family functioning (couple conflict and maternal depression), whereas maternal postnatal depression appears to affect children through other mechanisms, potentially including direct mother-infant interaction and care.

Although pediatric professional guidelines emphasize addressing a child’s social environment in the context of well child care, it remains unclear whether screening for unmet basic needs at visits increases low-income families’ receipt of community-based resources.

This study demonstrates that systematically screening and referring for social determinants of health during primary care can lead to the receipt of more community resources for families. (Read the full article)

Measles-containing vaccines are associated with several types of adverse events. Because measles-mumps-rubella-varicella (MMRV) versus separate measles-mumps-rubella (MMR) and varicella (MMR + V) vaccine increases a toddler’s risk for febrile seizures, we investigated whether MMRV is riskier than MMR + V and whether either vaccine elevates risk for additional safety outcomes.

Comparing MMRV with MMR + V, no increased risk of immune thrombocytopenia purpura, anaphylaxis, ataxia, arthritis, meningitis/encephalitis, acute disseminated encephalomyelitis, and Kawasaki disease was detected. No new safety concerns were identified after either vaccine, and most outcomes studied were unlikely after either vaccine. (Read the full article)

Head Start, a federally funded preschool program for low-income US children, has been reported to have beneficial effects on developmental outcomes. The association of Head Start participation with changes in children’s BMI has not been examined.

Preschool-aged children with an unhealthy weight status who participated in Head Start had a significantly healthier BMI by kindergarten entry age than comparison children in a primary care health system (both those receiving and those not receiving Medicaid). (Read the full article)

Pediatric traumatic brain injury (TBI) contributes to impairments in functioning across multiple settings. Online family problem-solving therapy may be effective in reducing adolescent behavioral morbidity after TBI. However, less is known regarding maintenance of effects over time.

This large randomized clinical trial in adolescents with TBI is the only study to examine maintenance of treatment effects. Findings reveal that brief, online treatment may result in long-term improvements in child functioning, particularly among families of lower socioeconomic status. (Read the full article)

Studies examining early postnatal discharge and readmission for jaundice report conflicting results. Infants born 37 to 38 weeks’ gestation have an increased risk for readmission for jaundice; however, the impact of early discharge on this group has not been investigated.

Early postnatal discharge was significantly associated with readmission for jaundice. Of the infants discharged early, those born 37 to 38 weeks’ gestation, born via vaginal delivery, born to Asian mothers, or were breastfed had the greatest risk for readmission. (Read the full article)

Behavioral observations influence a clinician’s decision to diagnose or refer, and may even override formal screening results. In the case of autism spectrum disorder, an expected rate of atypical behavior during the span of a medical visit is unknown.

We are the first to quantify the high base rates of typical behavior in young children who have autism and language delay. When observation times are brief, the preponderance of typical behaviors may negatively impact referral decision accuracy. (Read the full article)

Poverty is prevalent among children in the United States, and it has a clear association with negative health outcomes. Smoking and passive smoke exposure are both more common among socioeconomically disadvantaged populations and are associated with asthma morbidity.

Reported family hardships were common among children admitted for asthma or wheezing, and most were associated with detectable tobacco smoke exposure. The cumulative number of hardships was also associated with greater odds of tobacco smoke exposure. (Read the full article)

Researchers speculate that children with fetal alcohol spectrum disorders often are not recognized or diagnosed correctly.

This is the first study to assess the rate of missed diagnoses and misdiagnosis in foster and adopted children with fetal alcohol spectrum disorders. (Read the full article)

Meningococcal disease is a serious but rare infectious disease. In 2012, the incidence of meningococcal disease was at a historic low in the United States; however, incidence remained highest among infants aged <1 year.

This report describes the epidemiology and burden of meningococcal disease in infants aged <1 year in the United States and potential risk factors for transmission to this vulnerable group. These data are key to informing future meningococcal disease vaccination strategies. (Read the full article)

Light and intermittent smoking are harmful, but increasingly common, smoking patterns. It is unknown how adolescents perceive these smoking patterns, and whether these views differ by sociodemographic characteristics, and exposure to and use of tobacco.

US adolescents perceive light and intermittent smoking as significantly less dangerous than heavier smoking. One in 4 adolescents believes intermittent smoking causes little to no harm. Perceptions of relative safety were common among smokers. (Read the full article)
