RESUMEN

INTRODUCTION: Due to the nonspecific clinical presentation, clinicians often empirically treat newborns at risk of early-onset sepsis (EOS). Recently, the Canadian Paediatric Society (CPS) published updated recommendations that promote a more judicious approach to EOS management. OBJECTIVE: To examine the compliance with the CPS statement at a tertiary perinatal site and characterize the types of deviations. METHODS: A retrospective chart review was conducted for all term and late pre-term newborns at risk for sepsis, between January 1 and June 30, 2018. The prevalence of newborns with EOS risk factors was measured during the first month. Management strategies for eligible newborns during the 6-month period were compared to the CPS recommendations to establish the rate of noncompliance. The type of noncompliance, readmission rate, and rate of culture-positive EOS were examined. RESULTS: In the first month, 29% (66 of 228) of newborns had EOS risk factors. Among the 100 newborns born in the 6-month period for whom the CPS recommendations apply, 47 (47%) received noncompliant management. Of those, 51% (N=24) had inappropriately initiated investigations, 17% (N=8) had inappropriate antibiotics, and 32% (N=15) had both. The rate of readmission for a septic workup was 1.6% (N= 2). None had culture-positive sepsis while admitted. CONCLUSION: A large proportion of term and late preterm newborns (29%) had EOS risk factors, but none had culture-confirmed EOS. The rate of noncompliance with the CPS recommendations was high (47%), mainly due to overzealous management. Future initiatives should aim at increasing compliance, particularly in newborns at lower EOS risk.

RESUMEN

Importance: Maternal docosahexaenoic acid (DHA) supplementation may prevent bronchopulmonary dysplasia, but evidence remains inconclusive. Objective: To determine whether maternal DHA supplementation during the neonatal period improves bronchopulmonary dysplasia-free survival in breastfed infants born before 29 weeks of gestation. Design, Setting, and Participants: Superiority, placebo-controlled randomized clinical trial at 16 Canadian neonatal intensive care units (June 2015-April 2018 with last infant follow-up in July 2018). Lactating women who delivered before 29 weeks of gestation were enrolled within 72 hours of delivery. The trial intended to enroll 800 mothers, but was stopped earlier. Interventions: There were 232 mothers (273 infants) assigned to oral capsules providing 1.2 g/d of DHA from randomization to 36 weeks' postmenstrual age and 229 mothers (255 infants) assigned to placebo capsules. Main Outcomes and Measures: The primary outcome was bronchopulmonary dysplasia-free survival in infants at 36 weeks' postmenstrual age. There were 22 secondary outcomes, including mortality and bronchopulmonary dysplasia. Results: Enrollment was stopped early due to concern for harm based on interim data from this trial and from another trial that was published during the course of this study. Among 461 mothers and their 528 infants (mean gestational age, 26.6 weeks [SD, 1.6 weeks]; 253 [47.9%] females), 375 mothers (81.3%) and 523 infants (99.1%) completed the trial. Overall, 147 of 268 infants (54.9%) in the DHA group vs 157 of 255 infants (61.6%) in the placebo group survived without bronchopulmonary dysplasia (absolute difference, -5.0% [95% CI, -11.6% to 2.6%]; relative risk, 0.91 [95% CI, 0.80 to 1.04], P = .18). Mortality occurred in 6.0% of infants in the DHA group vs 10.2% of infants in the placebo group (absolute difference, -3.9% [95% CI, -6.8% to 1.4%]; relative risk, 0.61 [95% CI, 0.33 to 1.13], P = .12). Bronchopulmonary dysplasia occurred in 41.7% of surviving infants in the DHA group vs 31.4% in the placebo group (absolute difference, 11.5% [95% CI, 2.3% to 23.2%]; relative risk, 1.36 [95% CI, 1.07 to 1.73], P = .01). Of 22 prespecified secondary outcomes, 19 were not significantly different. Conclusions and Relevance: Among breastfed preterm infants born before 29 weeks of gestation, maternal docosahexaenoic acid supplementation during the neonatal period did not significantly improve bronchopulmonary dysplasia-free survival at 36 weeks' postmenstrual age compared with placebo. Study interpretation is limited by early trial termination. Trial Registration: ClinicalTrials.gov Identifier: NCT02371460.

RESUMEN

BACKGROUND/OBJECTIVES: Rapid genome-wide sequencing (rGWS) continues to transform the care provided to infants with genetic conditions in neonatal intensive care units (NICUs). Previous research has demonstrated that rGWS has immense benefits on patient care; however, little is known about non-genetic healthcare providers' (HCPs) experiences and perspectives of working with rGWS and supporting families through the rGWS testing process in Canadian NICU facilities. To address this gap, we surveyed and conducted semi-structured interviews with non-genetic HCPs of diverse professions from NICUs in British Columbia. METHODS: An interpretive description approach was used to analyze interview transcripts to identify patterns and variations in non-genetic HCPs' experiences and perceptions with rGWS. RESULTS: Participants had varying degrees of exposure to rGWS and levels of comfort with the testing process. Numerous barriers affecting the implementation of rGWS were identified, including low levels of comprehension of rGWS, longer turn-around times than expected, and having to apply for provincial government approval to access testing. Participants desired more education on rGWS, clear guidelines on the use of rGWS in NICUs, and resources for non-genetic HCPs and parents to support implementation. CONCLUSIONS: The results from this study can inform the development of workflows and educational resources on the use of rGWS in NICUs, helping to ensure that the NICU team is supported to optimize rGWS implementation.

RESUMEN

OBJECTIVES: To determine whether maternal supplementation with high-dose docosahexaenoic acid (DHA) in breastfed, very preterm neonates improves neurodevelopmental outcomes at 18 to 22 months' corrected age (CA). METHODS: Planned follow-up of a randomized, double-blind, placebo-controlled, multicenter trial to compare neurodevelopmental outcomes in breastfed, preterm neonates born before 29 weeks' gestational age (GA). Lactating mothers were randomized to receive either DHA-rich algae oil or a placebo within 72 hours of delivery until 36 weeks' postmenstrual age. Neurodevelopmental outcomes were assessed with the Bayley Scales of Infant and Toddler Development third edition (Bayley-III) at 18 to 22 months' CA. Planned subgroup analyses were conducted for GA (<27 vs ≥27 weeks' gestation) and sex. RESULTS: Among the 528 children enrolled, 457 (86.6%) had outcomes available at 18 to 22 months' CA (DHA, N = 234, placebo, N = 223). The mean differences in Bayley-III between children in the DHA and placebo groups were -0.07 (95% confidence interval [CI] -3.23 to 3.10, P = .97) for cognitive score, 2.36 (95% CI -1.14 to 5.87, P = .19) for language score, and 1.10 (95% CI -2.01 to 4.20, P = .49) for motor score. The association between treatment and the Bayley-III language score was modified by GA at birth (interaction P = .07). Neonates born <27 weeks' gestation exposed to DHA performed better on the Bayley-III language score, compared with the placebo group (mean difference 5.06, 95% CI 0.08-10.03, P = .05). There was no interaction between treatment group and sex. CONCLUSIONS: Maternal DHA supplementation did not improve neurodevelopmental outcomes at 18 to 22 months' CA in breastfed, preterm neonates, but subgroup analyses suggested a potential benefit for language in preterm neonates born before 27 weeks' GA.

RESUMEN

OBJECTIVE: The aim of the present retrospective study was to describe the use of nasal continuous positive airway pressure (NCPAP) and the prevalence of bronchopulmonary dysplasia (BPD). STUDY DESIGN: Data from 1526 neonates with gestational age less than 32 weeks, admitted to Children's and Women's Health Centre of British Columbia (Vancouver, British Columbia) between period 1 (1996 to 2000) and period 2 (2000 to 2004) were analyzed. The use of respiratory therapies and outcomes were retrospectively compared before and after the introduction of a NCPAP approach to respiratory support. RESULTS: A significant increase in the use of NCPAP was noted between periods 1 and 2 (60% versus 71%), as well as a significant reduction in the use of surfactant (50% versus 41%), postnatal steroids (30% versus 10%) and the need for mechanical ventilation (77% versus 64%). In period 2, there was a significant reduction in the prevalence of BPD at 28 days (33% versus 26%), higher prevalence of severe retinopathy of prematurity (3% versus 6%) and less periventricular leukomalacia (4% versus 2%). CONCLUSIONS: A significant increase in the use of NCPAP therapy in the neonatal unit has been associated with a decrease in the use of more invasive therapies. The incidence of BPD has decreased if defined as need for supplemental oxygen at 28 days of age, but not when the 36 weeks' postconceptional age criterion was used. NCPAP therapy may decrease the use of more invasive therapies and may improve respiratory outcomes. The impact of this intervention on nonrespiratory outcomes warrants further investigation.

RESUMEN

We report a sick preterm neonate with a dramatic ileus presentation mimicking necrotizing enterocolitis that promptly reversed upon hydrocortisone supplementation. Because our case illustrates a previously unsuspected clinical visage of inadequate adrenal responses in sick preterm neonates, it also emphasizes the need for improved diagnostic algorithms to identify neonates who could potentially benefit from treatment while avoiding the morbid consequences of unwarranted corticosteroids use in this population.

RESUMEN

Herpes simplex virus encephalitis in the newborn typically involves the cerebral cortex in a widespread manner. Herpes simplex virus type 2 rarely involves the brainstem. Here we report a 16-day-old infant with predominant brainstem and cerebellar involvement secondary to herpes simplex virus type 2 infection. Diffusion-weighted MRI performed 3 days after the onset of symptoms revealed restricted diffusion mainly in brainstem and cerebellar structures. No abnormal findings were seen on conventional MRI. Subsequent MRI scans showed evolution of the brain injury with extension along the corticospinal tracts. However, there was no evidence of any other supratentorial gray or white matter injury. This is the first report of predominant brainstem involvement in neonatal herpes simplex virus type 2 encephalitis. In addition, the importance of performing diffusion-weighted sequences to detect early central nervous system involvement and serial MRI to follow the evolution of central nervous system lesions is emphasized.
