Although morbidity-free survival for preterm infants has remained constant in US NICUs when assessed collectively, morbidity-free survival differs among centers. Center-specific practices before, at, or after delivery might affect outcomes of the most premature infants.

Our findings suggest that the approach taken to infants at the limits of viability is associated with outcomes of more-mature infants. Identifying centers with higher survival and lower morbidity might lead to identification of key practices to improve morbidity-free survival. (Read the full article)

Preterm children born between 29 and 36 gestational weeks are at higher risk of developmental delay. The Ages and Stages Questionnaires (ASQ) have been recommended as a developmental screening tool.

At 12 months’ corrected age (CA), the ASQ was insufficient in identifying delays on both mental and psychomotor scales of the Bayley Scales of Infant Development but was accurate in detecting mental delay at CA of 24 months. (Read the full article)

Previous studies show beneficial effects of cycled lighting in neonatal care on infant day–night activity, sleep behavior, and postnatal growth. The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists recommend neonatal care under cycled lighting conditions.

This study found that cycled lighting during neonatal care reduces infant’s fussing and crying behavior at 5 and 11 weeks’ corrected age and improves growth during neonatal period. These findings support the introduction of cycled lighting in neonatal care practice. (Read the full article)

Death or neurodevelopmental impairment in extremely premature neonates can be predicted at birth by considering gender, antenatal steroids, multiple birth, birth weight, and gestational age.

Prediction of death or neurodevelopmental impairment in extremely premature infants is improved by using information available later during the clinical course. The importance of birth weight declines, whereas that of respiratory illness severity increases with advancing postnatal age. (Read the full article)

Male circumcision reduces risk of HIV acquisition in men by 60% and is associated with other health benefits. Compared with adult circumcision, infant male circumcision is safer, less expensive, and represents a cost-saving intervention for HIV prevention in many settings.

IMC is little known in East Africa and is not routinely practiced. This is the first study to assess acceptability and uptake of IMC in East Africa among parents who were actually offered the procedure. (Read the full article)

Febrile infants in the first 90 days may have life-threatening serious bacterial infection. Well-appearing febrile infants with serious bacterial infections cannot be distinguished from those without by examination alone. Variation in care resulting in both undertreatment and overtreatment is common.

The systemwide implementation of an evidence-based care process model for the care of febrile infants in Intermountain Healthcare was associated with increased delivery of evidence-based care, improved infant outcomes, and lower costs. This model adopted nationally can improve value. (Read the full article)

There is no literature on the concentrations of vitamin B₆ vitamers in cerebrospinal fluid of preterm and term newborn infants. This knowledge, however, is highly important, because vitamin B₆ plays a pivotal role in brain development and functioning.

In cerebrospinal fluid of newborn infants, B₆ vitamer concentrations are strongly dependent on postmenstrual age, indicating that vitamin B₆ homeostasis in brain differs between preterm and term newborns. This has implications for the evaluation of epilepsy and vitamin B₆ deficiency. (Read the full article)

Preterm infants from 33 gestational weeks can detect specific shape features (prism and cylinder) by touch (without visual control), and remember them; however, nothing is known about such abilities earlier in development.

The preterm infant, even when very immature (from 28 gestational weeks), is endowed with tactile sensory abilities: the exploration and memorization of an object by touch, the discrimination of a novel object, and the recognition of a familiar object after interference. (Read the full article)

Data suggest that delivery at high-volume, high-technology hospitals reduces neonatal mortality. No study has examined other complications or compared the effects in multiple states by using a study design to control for unmeasured differences in case mix.

The survival benefit to delivering at a high-level NICU between 1995 and 2005 is larger than previously reported and varies between states. The survival benefits affect both extremely and moderately preterm infants. Complication rates were similar between hospital types. (Read the full article)

Sudden infant death syndrome remains the major cause of postneonatal death in developed countries. Although infant-parent bed-sharing following antenatal smoking or maternal consumption of alcohol on the bed-sharing night increases the risk of death, the mechanism is not known.

Bed-sharing infants experienced more oxygen desaturations and episodes of carbon dioxide rebreathing than cot-sleeping infants but showed appropriate behavioral and physiologic responses. A deficit in these responses in vulnerable infants could link to increased risk of sudden infant death syndrome. (Read the full article)

Infantile hemangiomas have a period of rapid growth in early infancy. Most hemangioma growth is completed by 5 months of age, but the majority of patients are not seen by a specialist until after the growth phase is complete.

The most rapid hemangioma growth is between 1 and 2 months of life, much earlier than previously believed. Patients with high-risk hemangiomas should be followed closely, and treatment initiation should be considered before or during the most rapid growth phase. (Read the full article)

Food insecurity has been linked to childhood obesity in a number of studies. Few studies have explored potential pathways through which food insecurity is related to child weight, especially in low-income families with young infants.

We found that food insecurity was related to maternal controlling feeding styles and concerns about the infants’ future weight. Early obesity prevention should aim to decrease food insecurity and to reduce controlling feeding styles in families who remain food insecure. (Read the full article)

Childhood obesity occurs in 20% of children before they enter kindergarten. Treatment is difficult, making prevention desirable, but little is known about effective methods using anticipatory guidance to prevent obesity in pediatric primary care.

This study provides a comparison of 2 approaches versus usual care using anticipatory guidance to improve infant feeding during the first year of life, and demonstrates positive specific feeding behavior differences at 1 year in the intervention groups. (Read the full article)

Cholestasis predisposes to the development of fat-soluble vitamin (FSV) deficiency. D-α tocopheryl polyethylene glycol-1000 succinate and coadministered FSVs are absorbed in spite of cholestasis.

Infants with biliary atresia with total bilirubin >2 mg/dL are at risk for fat-soluble vitamin (FSV) deficiency. A multivitamin preparation containing d-α tocopheryl polyethylene glycol-1000 succinate alone is not effective in treating biochemical FSV insufficiency in cholestatic infants. (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)

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)

Declining dietary omega 3 polyunsaturated fatty acids has been associated with rising allergy prevalence and fish oil is therefore of interest in allergy prevention. Supplementation during pregnancy, but not after the age of 6 months, has achieved some allergy reductions.

We assessed the effect of fish oil supplementation from birth to 6 months, which has not been investigated previously. Our results, together with previous findings, will likely help define a "window of opportunity" for allergy intervention using fish oil supplements. (Read the full article)

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)

Behavioral techniques effectively reduce infant sleep problems and associated maternal depression in the short- to medium-term (4–16 months’ postintervention). Despite their effectiveness, theoretical concerns persist about long-term harm on children’s emotional development, stress regulation, mental health, and the child-parent relationship.

Behavioral sleep techniques did not cause long-lasting harms or benefits to child, child-parent, or maternal outcomes. Parents and health professionals can feel comfortable about using these techniques to reduce the population burden of infant sleep problems and maternal depression. (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 Apgar score is a convenient method to rapidly assess the clinical status of the newborn infant. Recent literature suggests Apgar scores vary widely in preterm infants.

The Apgar signs for respiratory effort, grimace, and muscle tone demonstrated considerable disagreement in preterm infants ≤28 weeks’ gestation. Disagreement exists despite the level of respiratory intervention, continuous positive airway pressure, or intubation, and is likely independent of gestational age. (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)

Despite numerous preventive strategies including prophylaxis with 400 IU/day of vitamin D in recent years, the deficiency of vitamin D in infants is still a global health problem.

This study reveals that the risk of vitamin D deficiency is high in exclusively breastfed infants, especially in winter, despite vitamin D supplementation. Therefore, it is suggested that an adjustment of vitamin D dosage for seasonal variation might be necessary. (Read the full article)

Children born late preterm (34–36 weeks’ gestation) are at increased risk of adverse early childhood outcomes compared with term-born children. The impact of the neonatal experience on longer-term outcomes of these infants has not yet been well considered.

This study provides information regarding the development of late preterm infants at 3 years. Late preterm infants who received neonatal intensive or high-dependency care had similar developmental outcomes to children born late preterm who did not receive this care. (Read the full article)

Infant behavioral dysregulation is a common concern, involving irritability, excessive crying, and problems with feeding and sleep. Previous research into its behavioral outcomes has been limited by small cohorts and short follow-up, and findings have been contradictory.

Long-term follow-up of a large cohort showed that infant behavioral dysregulation was a risk factor for maternal-reported behavior concerns at 5 and 14 years, but was unrelated to young adult mental health outcomes. (Read the full article)

Retinal hemorrhages occur in accidental and inflicted traumatic brain injury (ITBI) and some medical encephalopathies. Large numbers and peripherally located retinal hemorrhages are frequently cited as distinguishing features of ITBI in infants, but the predictive value has not been established.

This prospective retinal imaging study found that a diagnosis of ITBI in infants and children can be distinguished from other traumatic and nontraumatic causes by the presence of >25 dot-blot (intraretinal layer) hemorrhages (positive predictive value = 93%). (Read the full article)

Invasive Cronobacter infection is a rare but devastating disease known to affect hospitalized premature or immunocompromised infants fed powdered infant formulas (PIFs). PIF labels imply that powdered formulas are safe for healthy, term infants if the label instructions are followed.

Cronobacter can also infect healthy, term infants in the first months of life, even if PIF label instructions are followed. Invasive Cronobacter infection is extremely rare in exclusively breastfed infants or those fed commercially sterile, ready-to-feed formulas. (Read the full article)

Several meta-analyses evaluating probiotics in preterm infants suggest a beneficial effect for the prevention of necrotizing enterocolitis and death, but less for nosocomial infection. Lactobacillus reuteri may reduce these outcomes because of its immunomodulation and bactericidal properties.

Although L reuteri did not appear to decrease the rate of death or nosocomial infection, the trends suggest a protective role consistent with the literature. Feeding intolerance and duration of hospitalization were significantly decreased in premature infants ≤1500 g. (Read the full article)

The CPT1A p.P479L variant is common to northern aboriginal populations, leads to reduced enzyme activity, and may be associated with increased infant mortality rates.

The p.P479L variant is common in British Columbia First Nations with a coastal distribution correlated with regions of high infant mortality. Homozygotes display an altered acylcarnitine profile and are overrepresented in cases of sudden unexpected infant death in these areas. (Read the full article)

Nasal continuous positive airway pressure (NCPAP) is commonly given to premature infants with nasal prongs and nasal masks. Prongs and masks appear to injure the nose of preterm infants with equal frequency.

Nasal masks are more effective than nasal prongs for preventing intubation and mechanical ventilation in premature infants within 72 hours of starting NCPAP. (Read the full article)

Postnatal growth restriction of preterm infants is a universal problem. Early "catch-up growth" has been associated with development of metabolic syndrome. In addition, preterm infants appear to be at major risk for developing increased adiposity and insulin resistance.

The consumption of a nutrient-enriched formula after hospital discharge may be beneficial in adequate for gestational age infants both in terms of head circumference growth and fat-free mass gain. (Read the full article)

Randomized controlled trials of early developmental interventions for very preterm infants demonstrate short-term benefits for infant neurobehavioral functioning. The longer-term benefits of these interventions for children and their families are not yet clear.

This randomized trial shows that home-based preventive care over the first year of life for very preterm infants has selective long-term benefits. Caregivers report less anxiety and fewer were at risk for an anxiety disorder. Preschoolers show fewer internalizing behaviors. (Read the full article)

Patients living in rural versus urban counties encounter different health care environments. Whether these differences result in different health care utilization for rural versus urban infants is not known.

In this study, infants living in rural California counties were hospitalized less often than infants living in urban counties. Among those hospitalized, infants living in rural counties were hospitalized for fewer cumulative days than infants residing in urban counties. (Read the full article)

It has been widely thought for the past 20 years that recurrent low blood glucose levels ≤2.5 mmol/L (45 mg/dL), even in the absence of any suggestive clinical signs, can harm a preterm infant’s long-term development.

This prospective study showed the outcome at 2 and 15 years later for the preterm infants who had a blood glucose level this low in the first 10 days of life did not differ from that of matched controls. (Read the full article)

Stressful events adversely affect the immune system, particularly the natural killer (NK) cells. Infants in the NICUs are exposed to stressful stimuli. The effect of massage therapy on the immune system of preterm infants has not been investigated.

This randomized placebo-controlled study found daily massage performed in stable preterm infants for a minimum of 5 days was associated with an increase in NK cell cytotoxicity despite lower absolute NK cell numbers compared with controls. (Read the full article)

Osteopathy of prematurity continues to occur in preterm infants. Osteopathy of prematurity can cause rib fractures in ex-preterm infants.

Rib fractures in ex-preterm infants are often posterior and multiple. Posterior rib fractures may not be diagnostic of nonaccidental injury in ex-preterm infants. (Read the full article)

Delayed meconium passage impairs gastrointestinal function in premature infants. No intervention has been identified that accelerates meconium passage sufficiently. Gastrografin is an osmotic contrast agent used for radiologic examination of the bowel or for conservative treatment of uncomplicated meconium ileus.

Gastrografin did not accelerate complete meconium evacuation but stimulated gastrointestinal motility in a randomized, placebo-controlled trial in premature infants. Application shortened the time to full enteral feedings and hospital stay but was associated with necrotizing enterocolitis as a possible adverse event. (Read the full article)

Endotracheal intubation of newborn infants is a common procedure. Competency in this skill is mandatory for many pediatric training programs. The safety and benefits of using a stylet for intubating newborn infants are unknown.

Pediatric trainees are commonly unsuccessful at performing endotracheal intubation. Adverse events of using a stylet are uncommon. The use of a stylet does not increase success rates. (Read the full article)

Low birth weight (LBW) infants (<2500 g) are at risk for cognitive and behavioral problems later in life. During infancy, they are also at risk for iron deficiency, which has been associated with impaired neurodevelopment in other high-risk groups.

Iron supplementation during the first 6 months of life to LBW infants reduces the risk of behavioral problems at 3.5 years. Mild iron deficiency in infancy may be an important, preventable contributor to behavioral problems in children born with LBW. (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)

Survival estimates for preterm infants are vital for counseling parents, informing care, and planning services. Widely use estimates of in-unit survival derived from a large UK population for infants born at <33 weeks’ gestational age have been available since 1999.

These survival charts have been updated and will be of use to clinicians, parents, and managers. An alternative method for graphical representation of survival probabilities is offered: contour survival plots. (Read the full article)

The American Academy of Pediatrics recommends that infants <1500 g birth weight receive an iron intake of 4 mg/kg per day. There are no randomized trials to support this recommendation.

This trial compared the effect of iron supplementation of 2 mg/kg per day on the hematocrit at 36 weeks' postmenstrual age. This study concluded that iron supplementation does not affect the 36-week hematocrit or the number of transfusions in infants <1500 g. (Read the full article)

Impaired visual development has been reported in infants born to mothers prescribed methadone in pregnancy. Immature visual evoked potentials have been reported in this population, but data were confounded by gestation, growth restriction, and illicit drug use.

Visual evoked potentials are small and immature in infants exposed to methadone and other drugs of misuse in utero. These changes are independently associated with methadone exposure and persist after controlling for gestation, socioeconomic deprivation, alcohol consumption, and cigarette smoking.

Celiac disease is increasing in several countries and has emerged as a public health problem. Infant feeding has been suggested to affect celiac disease development and/or clinical expression. However, evidence-based complementary feeding strategies are limited.

Significant difference in celiac disease prevalence between 2 cohorts of 12-year-olds indicates an option for disease prevention. The cohorts differed in infant feeding, and our findings suggest that gradual introduction of gluten in small amounts during ongoing breastfeeding is favorable. (Read the full article)

There is a lack of consensus regarding the optimal investigative approach after a first febrile urinary tract infection. This is because of uncertainty regarding the long-term clinical significance of vesicoureteral reflux and urinary tract infection–related renal scarring.

No ideal diagnostic algorithm exists. We found marked variability in sensitivity and specificity for detection of abnormalities using current protocols. We also highlight the considerable cost differences, both financially and in terms of radiation dose, of different protocols. (Read the full article)

Pediatric training programs use simulation for procedural skills training. Research demonstrates student satisfaction with simulation training, improved confidence, and improved skills when retested on a simulator. Few studies, however, have investigated the clinical impact of simulation education.

This is the first multicenter, randomized trial to evaluate the impact of simulation-based mastery learning on clinical procedural performance in pediatrics. A single simulation-based training session was not sufficient to improve interns’ clinical procedural performance. (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.

While obesity-promoting eating, sedentary and physical activity behaviors, and increased prevalence of adiposity are evident from early life, few high-quality studies have evaluated interventions that seek to influence the development of these behaviors in very early childhood.

This study highlights the receptivity of first-time parents to interventions focused on their new infant’s eating and active play and provides evidence of effectiveness on some obesity-promoting behaviors in very early childhood. (Read the full article)

Although it is known that relatively minor abusive injuries sometimes precede more severe physical abuse, the prevalence of these previous injuries in infants evaluated for abuse was not known.

A history of bruising or oral injury in a precruising infant evaluated for abuse should heighten the level of suspicion because these injuries are common in abused infants and rare in infants found not to be abused. (Read the full article)
