Bayley-III Cognitive and Language Scales in Preterm Children

There is concern that the Bayley-III overestimates developmental functioning in preterm populations. The ability of the Bayley-III Cognitive and Language scales to predict later functioning in very preterm children has not been examined.

The norms on the Bayley-III Cognitive and Language scales at 24 months had low sensitivity for impairment across general cognitive, verbal and nonverbal reasoning domains at 4 years, which was better detected using cut-points based on local term-born reference data. (Read the full article)

Incidence and Outcomes of Symptomatic Neonatal Arterial Ischemic Stroke

Neonatal arterial ischemic stroke is associated with later cerebral palsy and cognitive impairment. Many studies on neonatal ischemic stroke are limited by modest sample sizes, and prospective studies that include outcomes assessments are scarce.

Results from this prospective, nationwide, population-based study provide information on the epidemiology, associated clinical variables, clinical manifestation, vascular distribution, and treatment of neonatal arterial ischemic stroke. The study also provides outcomes regarding motor function and cognition. (Read the full article)

Heart Rates in Hospitalized Children by Age and Body Temperature

Heart rate (HR) increases with increasing body temperature. Previous studies have characterized the relationship among HR, age, and temperature for patients in primary care and emergency department settings but not in hospitalized children.

Our data demonstrate an overall increase in HR by ~10 beats/minute for each 1°C increase in body temperature. Expected heart rates for hospitalized children differ from those for primary care and emergency department patients at the same age and temperature. (Read the full article)

Maternal Prepregnancy Body Mass Index and Child Psychosocial Development at 6 Years of Age

Both obesity and developmental disabilities have increased in recent decades; however, the full long-term effects of prepregnancy obesity on a child’s psychosocial development remain unknown. Limited studies suggest associations between maternal prepregnancy obesity and child psychosocial development.

This study in 6-year-old children provides evidence that severe prepregnancy obesity is associated with adverse child psychosocial outcomes, including attention-deficit/hyperactivity disorder. These findings were not explained by many pregnancy and postpartum factors related to maternal obesity or child development. (Read the full article)

The Early Benefits of Human Papillomavirus Vaccination on Cervical Dysplasia and Anogenital Warts

Clinical trials of the quadrivalent human papillomavirus vaccine show it to be highly efficacious in preventing vaccine-type–specific cervical dysplasia and anogenital warts, but few studies have assessed its effects in the real world and none have done so at the program/population level.

This study provides strong evidence of the early benefits of quadrivalent human papillomavirus vaccination on reductions in cervical dysplasia and possible reductions in anogenital warts among girls aged 14 to 17 years, offering additional justification for not delaying vaccination until girls are older.

Early Psychosocial Exposures, Hair Cortisol Levels, and Disease Risk

Early psychosocial exposures are increasingly recognized as crucial to health throughout life. A possible mechanism is physiologic dysregulation due to stress. Cortisol in hair is a new biomarker assessing long-term hypothalamic-pituitary-adrenal axis activity.

Added early psychosocial exposures seem to increase infant long-term hypothalamic-pituitary-adrenal axis activity and risk of common childhood diseases in a cumulative manner, supporting the model of physiologic dysregulation as a plausible mechanism through which early detrimental exposures determine health outcomes.

The Pharmacy-Level Asthma Medication Ratio and Population Health

Disparities in asthma morbidity are exacerbated by underutilization of preventive controller medications. Community pharmacies are well positioned for an increased role in population health. The Asthma Medication Ratio, currently used at the patient-level, could be adapted for use at the pharmacy-level.

A newly developed Pharmacy-level Asthma Medication Ratio was associated with population-level childhood asthma morbidity. Collaborative relationships between physicians, community pharmacists, and patients (and families) have the potential to promote testable interventions aimed at reducing asthma morbidity and cross-community disparities.

First Pertussis Vaccine Dose and Prevention of Infant Mortality

Few studies have established the protective efficacy of 1 to 3 primary doses of diphtheria-tetanus-whole-cell pertussis (DTwP)/diphtheria-tetanus-acellular pertussis (DTaP) vaccines against pertussis, hospitalization, or pertussis complications in infants. However, vaccine effectiveness against infant pertussis death has not been previously reported.

This is the first study to report the protective role of ≥1 DTwP/DTaP doses among vaccine-eligible infants aged ≥6 weeks against death, hospitalization, and complications from pertussis. It describes risk markers for death among vaccine-ineligible infants aged <6 weeks. (Read the full article)

Estimated Number of Infants Detected and Missed by Critical Congenital Heart Defect Screening

Newborn screening for critical congenital heart defects (CCHDs) has been implemented in many hospitals, yet there is uncertainty about the number of infants with CCHDs that might be detected through universal implementation of newborn CCHD screening in the United States.

We estimated that ~875 infants with CCHDs might be detected, and ~880 missed, annually through universal CCHD screening in the United States. Increases in prenatal diagnosis are unlikely to substantially impact the number of infants detected through CCHD screening. (Read the full article)

Sedentary Time in Late Childhood and Cardiometabolic Risk in Adolescence

Evidence on the cardiometabolic consequences of sedentary behavior in youth is inconsistent and mostly relies on cross-sectional studies. Studies with objective measures of sedentary time have found limited evidence of cross-sectional associations with adiposity markers but no other outcomes.

Objectively assessed daily sedentary time was not prospectively associated with cardiometabolic outcomes. Moderate to vigorous physical activity was beneficially associated with body fat mass, insulin, high-density lipoprotein cholesterol, and clustered cardiometabolic score. (Read the full article)

Head Growth and Neurocognitive Outcomes

Microcephaly is known to be associated with neurocognitive disorders and increasing head size with hydrocephalus. Head circumference is widely measured in childhood, but its practical value as a screening test is unclear.

Measured head size is not a stable characteristic and centile shifts occur very commonly, mostly reflecting measurement error or regression to the mean. Even where head size was consistently extreme, it was not a good predictor of later developmental problems. (Read the full article)

Ophthalmic Abnormalities and Reading Impairment

Dyslexia has a lifelong impact on learning. The consensus in the literature from clinical studies is that dyslexia is not caused by vision abnormalities. However, interventions and therapies directed at eye-related functions are still available.

In this cohort the majority of dyslexic children had normal results for all ophthalmic tests. These population-based data support the consensus that dyslexia is not primarily a vision problem and that vision-based therapies are not justified or likely to help. (Read the full article)

Youth Drinking in the United States: Relationships With Alcohol Policies and Adult Drinking

Youth drinking is associated with adult drinking. Alcohol policies can influence youth and adult drinking. However, it is unknown whether alcohol policies influence youth drinking patterns directly or through their effect on adult drinking.

Alcohol policies, including population-oriented policies, are protective for youth drinking. The effect of population-oriented policies may be mediated though effects on adults. These findings suggest that efforts to reduce youth drinking should rely on policies that address all age groups. (Read the full article)

Medical-Legal Strategies to Improve Infant Health Care: A Randomized Trial

US parents trust the health care system and bring their infant children in for preventive care. Previous studies have demonstrated the ability of health care systems to identify, and sometimes address, the economic needs of low-income families.

Families of newborns at a safety-net primary care center have high levels of economic hardship. Compared with controls, Developmental Understanding and Legal Collaboration for Everyone families had accelerated access to concrete supports, improved rates of on-time immunization and preventive care, and decreased emergency department utilization.

Physician Communication Training and Parental Vaccine Hesitancy: A Randomized Trial

Parental hesitancy about childhood vaccines is prevalent and related to delay or refusal of immunizations. Physicians are highly influential in parental vaccine decision-making, but may lack confidence in addressing parents’ vaccine concerns.

A physician-targeted communications intervention designed to reduce maternal vaccine hesitancy through the parent-physician relationship did not affect maternal hesitancy or physician confidence communicating with parents. Further research should determine the most effective approaches to addressing vaccine hesitancy. (Read the full article)

Prenatal Hemoglobin Levels and Early Cognitive and Motor Functions of One-Year-Old Children

Studies on the consequences of abnormal prenatal hemoglobin (Hb) concentration have focused on maternal morbidities and adverse birth outcomes. To date, very little is known about the association between prenatal Hb concentration and infant cognitive and motor functions.

There is an inverted U-shaped relationship between maternal Hb concentration and infant gross motor function. Hb concentration between 90 and 110 g/L appears to be optimal for early gross motor function of children. (Read the full article)

Cognition and Brain Structure Following Early Childhood Surgery With Anesthesia

Permanent neuronal deletion and neurocognitive impairment after anesthetic exposure in animals raised substantial concern that similar effects occur in children. Human studies were equivocal but have not combined structural and intelligence tests in otherwise healthy children after childhood anesthesia.

Anesthetic exposure for surgery did not lead to measurable neuronal elimination in brain regions previously identified in animals. However, language comprehension and performance IQ were decreased in exposed children and associated with decreased gray matter, primarily in posterior brain regions. (Read the full article)

Pneumococcal Conjugate Vaccine and Clinically Suspected Invasive Pneumococcal Disease

Conventional invasive pneumococcal disease (IPD) definition using laboratory confirmation lacks sensitivity. Using a vaccine-probe design, the FinIP trial showed that IPD disease burden and vaccine-preventable disease incidence were fourfold higher when a more sensitive outcome, clinically suspected IPD, was used.

Vaccine-preventable disease incidence (ie, absolute reduction due to PCV10 vaccination) during routine vaccination program was threefold with the more sensitive outcome of clinically suspected IPD compared with the conventional IPD definition. This has major implications for cost-effectiveness of PCVs. (Read the full article)

Weight Growth Velocity and Postnatal Growth Failure in Infants 501 to 1500 Grams: 2000-2013

Postnatal growth failure is common for very low birth weight infants. Although many of the major morbidities experienced by these infants during their initial NICU stays have decreased in recent years, it is unclear whether growth has improved.

For infants weighing 501 to 1500 g, average growth velocity increased and postnatal growth failure decreased from 2000 to 2013. Still, in 2013, half were discharged with a weight below the 10th percentile for postmenstrual age. (Read the full article)

Association of National Guidelines With Tonsillectomy Perioperative Care and Outcomes

Tonsillectomy guidelines make evidence-based recommendations for the perioperative use of dexamethasone, no routine use of antibiotics, and discharge education of families and for surgeons to monitor bleeding complication rates. The impact of the guidelines on processes and outcomes is unknown.

The guidelines were associated with improvement in perioperative care processes but no improvement in outcomes. Perioperative dexamethasone use increased slightly, and antibiotic use decreased substantially. Bleeding rates were stable, but revisit rates for complications increased because of revisits for pain.

Antibiotic Choice for Children Hospitalized With Pneumonia and Adherence to National Guidelines

The 2011 national guidelines for the management of pediatric community-acquired pneumonia recommended narrow-spectrum antibiotic therapy (eg, ampicillin) for most children hospitalized with pneumonia. Before the release of the guidelines, the use of broader-spectrum antibiotics (eg, third-generation cephalosporins) was much more common.

After release of the guidelines, third-generation cephalosporin use declined and penicillin/ampicillin use increased among children hospitalized with pneumonia. Changes were most apparent among institutions that proactively disseminated the guidelines, underscoring the importance of local efforts for timely guideline implementation.

Public Perceptions of the Benefits and Risks of Newborn Screening

Infant screening is valued by members of the lay public, but how different benefits are independently valued, and whether harms are disvalued, is not known. Public expectations of screening can inform decisions about what diseases to screen for.

The public values clinical benefits of screening and disvalues harms, with tolerance for harm proportional to clinical benefit. These findings support newborn screening policies prioritizing clinical benefits over solely informational benefits, coupled with concerted efforts to avoid or minimize harms.

Late Diagnosis of Coarctation Despite Prenatal Ultrasound and Postnatal Pulse Oximetry

Neonatal coarctation of the aorta (CoA) is a life-threatening cardiac defect, but because symptoms may be lacking initially, newborns with this defect are frequently discharged from the hospital undiagnosed. Delayed diagnosis of CoA is associated with increased morbidity and mortality.

This population-based study analyzes the contribution of prenatal ultrasound and postnatal pulse oximetry screening to the timely diagnosis of neonatal CoA. Both screening methods had low sensitivity for CoA. Nearly half of all newborns with isolated CoA were discharged undiagnosed. (Read the full article)

Use of Temporary Names for Newborns and Associated Risks

Because there can be no delay in providing newborns with identification wristbands, some hospitals assign newborns temporary first names such as Babyboy or Babygirl. These nondistinct naming conventions result in a large number of patients with similar identifiers in NICUs.

We performed an intervention study to determine if assigning distinct first names at birth would result in a reduction in wrong-patient errors. We used the Retract-and-Reorder tool, an established, automated tool to detect the outcome measure of wrong-patient electronic orders. (Read the full article)
