Considerable differences in outcome after extremely preterm birth have been reported between centers and regions providing a comparative level of care, but the reasons for these variations have been poorly examined.

In extremely preterm fetuses alive at the mother’s admission for delivery, and in infants born alive, mortality up to 2.5 years is reduced in regions with a more active use of perinatal interventions without increased neurodevelopmental morbidity. (Read the full article)

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)

Infants born extremely premature and infants born to adolescent mothers are at risk for adverse developmental and behavior outcomes. There is limited research on the dual risk imparted to infants born extremely premature to adolescent mothers.

Extremely premature infants of adolescent mothers have significantly increased rates of behavior problems. Nonwhite race and living in ≥3 places by 18 to 22 months of age are risk factors for adverse behavior outcomes among infants of adolescent mothers. (Read the full article)

Little is known about the prevalence or outcomes of infants with indeterminate diagnostic results after a positive cystic fibrosis (CF) newborn screen (CF transmembrane conductance regulator–related metabolic syndrome [CRMS]).

CRMS accounted for 15.7% of newborn screened diagnoses in the CF Patient Registry from 2010 to 2012 (CRMS:CF ratio = 5.0:1.0). Although most infants were healthy, some infants demonstrated clinical features concerning for CF. (Read the full article)

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)

Suboptimal brain development and increased risk of cognitive deficits are well documented in very low birth weight children. Supplementation with docosahexaenoic acid and arachidonic acid has been associated with positive cognitive effects.

This follow-up study of a randomized controlled trial of supplementation with docosahexaenoic acid and arachidonic acid to very low birth weight infants is the first report on both cognition and brain macrostructure measured with MRI. No cognitive or neuroanatomical effects were detected at 8 years. (Read the full article)

Distribution of infant formula discharge packs to breastfeeding mothers is common practice in maternity care facilities in the United States. Receiving discharge packs is associated with shortened exclusive breastfeeding duration. Many efforts have been made to discourage this practice.

From 2007 to 2013, there has been a marked reduction in distribution of discharge packs containing infant formula to breastfeeding mothers in hospitals and birth centers in the United States. (Read the full article)

The sensitivity of the urinalysis (UA) traditionally has been considered suboptimal in young infants. Whether the finding of a negative UA and a positive urine culture represents a false-negative UA versus a false-positive urine culture remains unclear.

In infants <3 months with bacteremic urinary tract infection, a condition that represents true infection, the UA sensitivity is higher than previously reported for urinary tract infection in general, suggesting that the UA is reliable even in young infants. (Read the full article)

Various clinical and demographic factors are associated with sudden infant death syndrome (SIDS), and an association between altitude of residence and SIDS has been questioned but not yet demonstrated in any large observational studies.

This study demonstrates an association between altitude and SIDS, with higher SIDS rates observed at high elevation (>8000 feet) than at the more moderate elevations (<6000 feet). (Read the full article)

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.

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)

Delayed cord clamping is recommended for all premature births, despite some studies suggesting a decreased placental transfusion at cesarean delivery.

Umbilical cord milking appears to improve systemic blood flow and perfusion in preterm infants delivered by cesarean delivery more efficiently than delayed cord clamping. (Read the full article)

Medicaid made substantial investments in enhanced prenatal and postnatal care programs to address maternal and infant health, including infant mortality. Evaluations of population-based programs are few, and although some have reported reductions in infant mortality, they have methodological limitations.

A population-based home visitation program can be a successful approach to reduce infant mortality. The reduced risk of infant death is consistent with previous findings on the effects of the program on health care utilization and birth outcomes. (Read the full article)

Parental adherence to recommended infant care practices (eg, breastfeeding; safe sleep) is below targeted goals. Adherence to practice recommendations increases when parents receive appropriate advice from multiple sources such as family and physicians.

Using a nationally representative sample, this study explores the advice mothers receive about safe sleep, immunization, breastfeeding, and pacifier use; the findings suggest infant care practices about which mothers receive little or inappropriate advice, suggesting possible targets for intervention.

Prenatal diagnosis may lead to benefits in outcomes for certain forms of critical congenital heart disease. Despite recognized benefits, single-center studies and focused regional efforts suggest that prenatal detection rates for congenital heart disease remain low in the United States.

We describe prenatal detection rates for a large cohort of neonates and infants undergoing heart surgery across a range of congenital heart defects. Additionally, this study adds new information by demonstrating geographic variability of prenatal detection rates across the United States. (Read the full article)

The routine childhood immunization schedule is crowded during the first 2 years, leading to deferred doses and limiting the addition of new vaccines. Combination vaccines can reduce the "shot burden" and improve coverage rates and timeliness.

Antibody response rates to antigens contained in an investigational hexavalent vaccine (DTaP5-IPV-Hib-HepB) were noninferior to licensed comparator vaccines when given as a 3-dose infant series. The safety profile was similar to control except for increased rates of mild-to-moderate, self-limited fever. (Read the full article)

Small-for-gestational-age neonates are at risk for thrombocytopenia during the first days and weeks after birth. However, the incidence, duration, severity, responsible mechanism, value of platelet transfusions, and risk of death from this variety of neonatal thrombocytopenia are unknown.

Ten percent of thrombocytopenic small-for-gestational-age neonates have a recognized cause for low platelets (aneuploidy, extracorporeal membrane oxygenation, disseminated intravascular coagulation); they have a high mortality rate (65%). Ninety percent have a moderate, transient (2 weeks), hyporegenerative thrombocytopenia with a low mortality rate (2%). (Read the full article)

Late preterm infants, compared with full-term infants, have less proficiency in reading and math at school age, with increased need for individualized educational plans and special education services. They also have lower cognitive performance on standardized IQ exams.

Late preterm infants have worse outcomes at school entry, and development is variable during the preschool years, so socioeconomic status, language spoken in the home, maternal education, maternal race, and being a late preterm infant have a large impact. (Read the full article)

The source of infant pertussis infection is typically identified ~50% of the time. Historically, mothers have been identified as the most common source of pertussis transmission to infants.

This analysis of 8 years of enhanced pertussis surveillance data has uncovered a shift in the most common source of infant pertussis infection in the United States from mothers to siblings. (Read the full article)

The vitamin D concentration in breast milk of women taking 400 IU vitamin D per day is relatively low, leading to vitamin D deficiency in breastfeeding infants. As a result, the American Academy of Pediatrics recommends breastfeeding infant vitamin D supplementation within days after birth.

Maternal vitamin D supplementation alone with 6400 IU/day safely supplies breast milk with adequate vitamin D to satisfy the requirement of her nursing infant and offers an alternate strategy to direct infant supplementation. (Read the full article)

Premature infants are at risk for medical and neurodevelopmental sequelae. Close monitoring is an important role for primary care providers. Premature infants have high use of health care services; however, little is known about the role of health supervision visits.

This study explores the utilization and value of health supervision visits for premature infants. Fewer than half were found to be fully adherent to the health supervision visit schedule, resulting in preventive care gaps and immunization delays. (Read the full article)

Small for gestational age neonates (weight <10th percentile) are at risk for neutropenia during the first days after birth. However, the duration, responsible mechanism, and outcomes of this variety of neonatal neutropenia are not precisely known.

Six percent of small for gestational age neonates had neutrophils <1000/μL, with an average neutropenia duration of 7 days. Neutropenia was more closely linked with small for gestational age status than maternal hypertension. This neutropenia is associated with elevated nucleated red blood cell count and increased odds of necrotizing enterocolitis. (Read the full article)

Central apnea sometimes complicates bronchiolitis. Because apnea tends to occur early in the course of bronchiolitis, there is a danger that infants may be discharged from the emergency department only to subsequently develop apnea at home.

This study prospectively derived clinical decision rules to help emergency physicians admit infants at risk for apnea while discharging those not at risk. (Read the full article)

Treatment of dogs naturally infected with Leishmania infantum using meglumine antimoniate (MA) encapsulated in conventional liposomes (LC) in association with allopurinol has been previously reported to promote marked reduction in the parasite burden in the main infection sites. Here, a new assay in naturally infected dogs was performed using a novel liposome formulation of MA consisting of a mixture of conventional and long-circulating (PEGylated) liposomes (LCP), with expected broader distribution among affected tissues of the mononuclear phagocyte system. Experimental groups of naturally infected dogs were as follows: LCP+Allop, receiving LCP intravenously as 2 cycles of 6 doses (6.5 mg Sb/kg/dose) at 4-day intervals, plus allopurinol at 30 mg/kg/12 h p.o. during 130 days; LC+Allop, receiving LC intravenously as 2 cycles of 6 doses (6.5 mg Sb/kg/dose), plus allopurinol during 130 days; Allop, treated with allopurinol only; non-treated control. Parasite loads were evaluated by quantitative PCR in liver, spleen and bone marrow and by immunohistochemistry in the ear skin, before, just after treatment and 4 months later. LCP+Allop and LC+Allop groups, but not the Allop group, showed significant suppression of the parasites in the liver, spleen and bone marrow 4 months after treatment, compared to the pre-treatment period or the control group. Only LCP+Allop group showed significantly lower parasite burden in the skin, in comparison to the control group. On the basis of clinical staging and parasitological evaluations, LCP formulation exhibited a more favorable therapeutic profile, when compared to LC one, being therefore promising for treatment of canine visceral leishmaniasis.

OBJECTIVES:

Infantile hemangiomas (IHs) are common; some cases require timely referral and treatment to prevent complications. We developed and validated a reliable instrument for timely and adequate referral of patients with IH to experts by nonexpert primary physicians.

Abusive head trauma (AHT) remains a significant cause of morbidity and mortality in the pediatric population, especially in young infants. In the past decade, advancements in research have refined medical understanding of the epidemiological, clinical, biomechanical, and pathologic factors comprising the diagnosis, thereby enhancing clinical detection of a challenging diagnostic entity. Failure to recognize AHT and respond appropriately at any step in the process, from medical diagnosis to child protection and legal decision-making, can place children at risk. The American Academy of Pediatrics revises the 2009 policy statement on AHT to incorporate the growing body of knowledge on the topic. Although this statement incorporates some of that growing body of knowledge, it is not a comprehensive exposition of the science. This statement aims to provide pediatric practitioners with general guidance on a complex subject. The Academy recommends that pediatric practitioners remain vigilant for the signs and symptoms of AHT, conduct thorough medical evaluations, consult with pediatric medical subspecialists when necessary, and embrace the challenges and need for strong advocacy on the subject.

We conducted a systematic review to demonstrate that tummy time was positively associated with gross motor development; prone, supine, crawling, and rolling development; reduction in BMI-z; and prevention of brachycephaly.

Using a matched cohort design, in this study, we define the adverse clinical and financial implications of UEs in the NICU.

Through propensity score analysis, we examine the effect of living in a segregated area on the development of neonatal IVH, stratified by maternal race.
