Perinatal morbidity among women with a previous caesarean delivery (PRISMA trial): a cluster-randomised trial. Lancet 2024; 403:44-54. [PMID: 38096892 DOI: 10.1016/s0140-6736(23)01855-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 08/20/2023] [Accepted: 08/31/2023] [Indexed: 01/08/2024]
Abstract
BACKGROUND Women with a previous caesarean delivery face a difficult choice in their next pregnancy: planning another caesarean or attempting vaginal delivery, both of which are associated with potential maternal and perinatal complications. This trial aimed to assess whether a multifaceted intervention, which promoted person-centred decision making and best practices, would reduce the risk of major perinatal morbidity among women with one previous caesarean delivery. METHODS We conducted an open, multicentre, cluster-randomised, controlled trial of a multifaceted 2-year intervention in 40 hospitals in Quebec among women with one previous caesarean delivery, in which hospitals were the units of randomisation and women the units of analysis. Randomisation was stratified according to level of care, using blocked randomisation. Hospitals were randomly assigned (1:1) to the intervention group (implementation of best practices and provision of tools that aimed to support decision making about mode of delivery, including an estimation of the probability of vaginal delivery and an ultrasound estimation of the risk of uterine rupture), or the control group (no intervention). The primary outcome was a composite risk of major perinatal morbidity. This trial was registered with ISRCTN, ISRCTN15346559. FINDINGS 21 281 eligible women delivered during the study period, from April 1, 2016 to Dec 13, 2019 (10 514 in the intervention group and 10 767 in the control group). None were lost to follow-up. There was a significant reduction in the rate of major perinatal morbidity from the baseline period to the intervention period in the intervention group as compared with the control group (adjusted odds ratio [OR] for incremental change over time, 0·72 [95% CI 0·52-0·99]; p=0·042; adjusted risk difference -1·2% [95% CI -2·0 to -0·1]). Major maternal morbidity was significantly reduced in the intervention group as compared with the control group (adjusted OR 0·54 [95% CI 0·33-0·89]; p=0·016). Minor perinatal and maternal morbidity, caesarean delivery, and uterine rupture rates did not differ significantly between groups. INTERPRETATION A multifaceted intervention supporting women in their choice of mode of delivery and promoting best practices resulted in a significant reduction in rates of major perinatal and maternal morbidity, without an increase in the rate of caesarean or uterine rupture.

Abstract
OBJECTIVE To compare neonatal and early-childhood outcomes of twins and singletons born preterm and explore the association of chorionicity with outcomes. STUDY DESIGN This was a national retrospective cohort study of singleton and twin infants admitted at 230/7-286/7 weeks to level III neonatal intensive care units in Canada (2010-2020). The primary neonatal outcome was a composite of neonatal death or severe neonatal morbidities. The primary early-childhood outcome was a composite of death or significant neurodevelopmental impairment. RESULTS The study cohort included 3554 twin and 12 815 singleton infants. Twin infants born at 230/7-256/7 weeks had a greater risk of the composite neonatal outcome (adjusted risk ratio 1.04, 95% CI 1.01-1.07). However, these differences were limited to the subgroups of same-sex and monochorionic twin pregnancies. Twin infants of 230/7-256/7 weeks were also at an increased risk of the composite early-childhood outcome (adjusted risk ratio 1.22, 95% CI 1.09-1.37). Twin infants of 260/7-286/7 weeks were not at an increased risk of adverse neonatal outcomes or the composite early-childhood outcome compared with singleton infants. CONCLUSIONS Among infants born at 230/7-256/7 weeks, twins have a greater risk of adverse neonatal outcomes and the composite early-childhood outcome than singleton infants. However, the increased risk of adverse neonatal outcomes is mostly limited to monochorionic twins and may thus be driven by complications related to monochorionic placentation.

Abstract
OBJECTIVE In a healthcare system with finite resources, hospital organisational factors may contribute to patient outcomes. We aimed to assess the association of nurse staffing and neonatal intensive care unit (NICU) occupancy with outcomes of preterm infants born <33 weeks' gestation. DESIGN Retrospective cohort study. SETTING Four level III NICUs. PATIENTS Infants born 23-32 weeks' gestation 2015-2018. MAIN OUTCOME MEASURES Nursing provision ratios (nursing hours worked/recommended nursing hours based on patient acuity categories) and unit occupancy rates were averaged for the first shift, 24 hours and 7 days of admission of each infant. Primary outcome was mortality/morbidity (bronchopulmonary dysplasia, severe neurological injury, retinopathy of prematurity, necrotising enterocolitis and nosocomial infection). ORs for association of exposure with outcomes were estimated using generalised linear mixed models adjusted for confounders. RESULTS Among 1870 included infants, 823 (44%) had mortality/morbidity. Median nursing provision ratio was 1.03 (IQR 0.89-1.22) and median unit occupancy was 89% (IQR 82-94). In the first 24 hours of admission, higher nursing provision ratio was associated with lower odds of mortality/morbidity (OR 0.93, 95% CI 0.89 to 0.98), and higher unit occupancy was associated with higher odds of mortality/morbidity (OR 1.19, 95% CI 1.04 to 1.36). In causal mediation analysis, nursing provision ratios mediated 47% of the association between occupancy and outcomes. CONCLUSIONS NICU occupancy is associated with mortality/morbidity among very preterm infants and may reflect lack of adequate resources in periods of high activity. Interventions aimed at reducing occupancy and maintaining adequate resources need to be considered as strategies to improve patient outcomes.

Abstract
OBJECTIVE To describe the incidence, trends, management's variability and short-term outcomes of preterm infants with severe post-hemorrhagic ventricular dilatation (sPHVD). METHODS We reviewed infants <33 weeks' gestation who had PHVD and were admitted to the Canadian Neonatal Network between 2010 and 2018. We compared perinatal characteristics and short-term outcomes between those with sPHVD and those with mild/moderate PHVD and those with and without ventriculo-peritoneal (VP) shunt. RESULTS Of 29,417 infants, 2439 (8%) had PHVD; rate increased from 7.3% in 2010 to 9.6% in 2018 (P = 0.005). Among infants with PHVD, sPHVD (19%) and VP shunt (29%) rates varied significantly across Canadian centers and between geographic regions (P < 0.01 and P = 0.0002). On multivariable analysis, sPHVD was associated with greater mortality, seizures and meningitis compared to mild/moderate PHVD. CONCLUSIONS Significant variability in sPHVD and VP shunt rates exists between centers and regions in Canada. sPHVD was associated with increased mortality and morbidities.

Abstract
Objectives To determine the efficacy and safety of sildenafil citrate to improve outcomes in pregnancies complicated by early-onset, dismal prognosis, fetal growth restriction (FGR). Eligibility: women ≥ 18 years, singleton, 18 + 0–27 + 6 weeks’ gestation, estimated fetal weight < 700 g, low PLFG, and ≥ 1 of (i) abdominal circumference < 10th percentile for gestational age (GA); or (ii) reduced growth velocity and either abnormal uterine artery Doppler or prior early-onset FGR with adverse outcome. Ineligibility criteria included: planned termination or reversed umbilical artery end-diastolic flow. Eligibility confirmed by placental growth factor (PlGF) < 5 th percentile for GA measured post randomization. Women randomly received (1:1) either sildenafil 25 mg three times daily or matched placebo until either delivery or 31 + 6 weeks. Primary outcome: delivery GA. The trial stopped early when Dutch STRIDER signalled potential harm; despite distinct eligibility criteria and IRB and DSMB support to continue, because of futility. NCT02442492 [registered 13/05/2015]. Results Between May 2017 and June 2018, 21 (90 planned) women were randomised [10 sildenafil; 11 placebo (1 withdrawal)]. Baseline characteristics, PlGF levels, maternal and perinatal outcomes, and adverse events did not differ. Delivery GA: 26 + 6 weeks (sildenafil) vs 29 + 2 weeks (placebo); p = 0.200. Data will contribute to an individual participant data meta-analysis.

Abstract
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.

Abstract
OBJECTIVE Nursing workload assessment tools are widely used to determine nurse staffing requirements in the neonatal intensive care unit (NICU). We aimed to compare three existing workload assessment tools and assess their association with mortality or morbidity among very preterm infants. STUDY DESIGN Single-center retrospective cohort study of infants born <33 weeks and admitted to a 52-bed tertiary NICU in 2017 to 2018. Required nurse staffing was estimated for each shift using the Winnipeg Assessment of Neonatal Nursing Needs Tool (WANNNT) used as reference tool, the Quebec Provincial NICU Nursing Ratio (QPNNR), and the Canadian NICU Resource Utilization (CNRU). Poisson regression models with robust error variance estimators were used to assess the association between nursing provision ratios (actual number of nurses/required number of nurses) during the first 7 days of admission and neonatal outcomes. RESULTS Median number of nurses required per shift using the WANNNT was 25.0 (interquartile range [IQR]: 23.1-26.7). Correlation between WANNNT and QPNNR was high (r = 0.92, p < 0.0001), but the QPNNR underestimated the number of nurses per shift by 4.8 (IQR: 4.1-5.4). Correlation between WANNNT and CNRU was moderate (r = 0.45, p < 0.0001). The NICU nursing provision ratios during the first 7 days of admission calculated using the WANNNT (adjusted risk ratio [aRR]: 0.96, 95% confidence interval [CI]: 0.93-0.99) and QPNNR (aRR: 0.97, 95% CI: 0.95-0.99) were associated with mortality or morbidity. CONCLUSION Lower nursing provision ratio calculated using the WANNNT and CNRU during the first 7 days of admission is associated with an increased risk of mortality/morbidity in very preterm infants. KEY POINTS · NICUs use different nursing workload assessment tools.. · We validated three different nursing workload assessment tools used in the NICU.. · Nursing provision ratio is associated the risk of mortality/morbidity in preterm infants..

Abstract
OBJECTIVE This study aimed to assess whether the hospital level of care where asphyxiated neonates treated with hypothermia were originally born influences their outcome. STUDY DESIGN We conducted a retrospective cohort study of all asphyxiated neonates treated with hypothermia in a large metropolitan area. Birth hospitals were categorized based on provincially predefined levels of care. Primary outcome was defined as death and/or brain injury on brain magnetic resonance imaging (adverse outcome) and was compared according to the hospital level of care. RESULTS The overall incidence of asphyxiated neonates treated with hypothermia significantly decreased as hospital level of care increased: 1 per 1,000 live births (109/114,627) in level I units; 0.9 per 1,000 live births (73/84,890) in level II units; and 0.7 per 1,000 live births (51/71,093) in level III units (p < 0.001). The rate of emergent cesarean sections and the initial pH within the first hour of life were significantly lower in level I and level II units compared with level III units (respectively, p < 0.001 and p = 0.002). In a multivariable analysis adjusting for the rates of emergent cesarean sections and initial pH within the first hour of life, being born in level I units was confirmed as an independent predictor of adverse outcome (adjusted odds ratio [OR] level I vs. level III 95% confidence interval [CI]: 2.13 [1.02-4.43], p = 0.04) and brain injury (adjusted OR level I vs. level III 95% CI: 2.41 [1.12-5.22], p = 0.02). CONCLUSION Asphyxiated neonates born in level I units and transferred for hypothermia treatment were less often born by emergent cesarean sections, had worse pH values within the first hour of life, and had a higher incidence of adverse outcome and brain injury compared with neonates born in level III units. Further work is needed to optimize the initial management of these neonates to improve outcomes, regardless of the location of their hospital of birth. KEY POINTS · The incidence of asphyxiated neonates treated with hypothermia varied by hospital level of care.. · Their rates of emergent cesarean sections and their initial pH within the first hour of life varied by hospital level of care.. · The hospital level of care was an independent predictor of their adverse outcome, defined as death and/or brain injury on brain MRI..

Abstract
INTRODUCTION The aim of the study was to determine the effect of a maternal docosahexaenoic acid (DHA) supplementation during lactation, compared with a placebo, on the neonatal growth profile of breastfed very preterm infants. METHODS Preterm infants' growth profile, growth velocity from birth to 36 weeks' postmenstrual age (PMA), and growth at 36 weeks' PMA were pre-specified secondary outcomes of a randomized placebo-controlled trial conducted in 16 Canadian neonatal intensive care units (2015-2018). Lactating mothers who delivered before 29 weeks' gestation were given 1.2 g of DHA daily or a placebo within 72 h of delivery and up to 36 weeks' PMA. Analyses were performed using a linear regression model with generalized estimating equations. RESULTS 461 mothers and their 528 infants (DHA, N = 273; placebo, N = 255) were included with mean gestational age of 26.5 weeks (standard deviation [SD] = 1.6); 275 (52.1%) were males; mean birth weight was 895 g (SD = 240). DHA interaction with sex was significant on weight profile (interaction p < 0.001), weight velocity (interaction p = 0.05), and weight at 36 weeks' PMA (interaction p = 0.02). Females in the DHA group gained more weight compared to the placebo group (mean difference [MD], 52.6 g [95% confidence interval [CI]: 24.5-80.8], p < 0.001). Weight velocity was significantly higher in females of the DHA group (MD, 3.4 g/kg/day [95% CI: 0.6-6.2], p = 0.02). At 36 weeks' PMA, the weight of males in the DHA group was significantly smaller (MD, -88.9 g [95% CI: -166.2 to -11.6], p = 0.02). CONCLUSION DHA positively affected female infants' neonatal weight profile and velocity and negatively affected male infants' weight at 36 weeks' PMA.

Abstract
OBJECTIVE To assess the association between time of birth and mortality among preterm infants. STUDY DESIGN Population-based study of infants born 22-36 weeks gestation (GA) in Canada from 2010 to 2015 (n = 173 789). Multivariable logistic regression models assessed associations between timing of birth and mortality. RESULT Among infants 22-27 weeks GA, evening birth was associated with higher mortality than daytime birth (adjusted odds ratio [AOR] 1.14, 95% CI 1.01-1.29). Among infants 28-32 weeks GA and 33-36 weeks GA, night birth was associated with lower mortality than daytime birth (AOR 0.75, 95% CI 0.59-0.95; AOR 0.78, 95% CI 0.62-0.99, respectively). Sensitivity analysis excluding infants with major congenital anomaly revealed that associations between hour of birth and mortality among infants born 28-32 and 33-36 weeks GA decreased or were not statistically significant. CONCLUSION Higher mortality among extremely preterm infants during off-peak hours may suggest variations in available resources based on time of day.

Abstract
Primary Subject area
Neonatal-Perinatal Medicine
Background
In a health care system with limited resources, hospital organizational factors such as unit occupancy and nurse-to-patient ratios may contribute to patient outcomes.
Objectives
We aimed to assess the association of NICU occupancy and nurse staffing with outcomes of very preterm infants born < 33 weeks gestational age (GA).
Design/Methods
This was a multicenter retrospective cohort study of infants born 23-32 weeks GA without major congenital anomaly, admitted within 2 days after birth to one of four Level 3 NICUs in Quebec, Canada (2015-2018). For each 8 h shift, data on unit occupancy were obtained from a central provincial database (SiteNeo) and linked to the hospital nursing hours database (Logibec). Unit occupancy rates and nursing provision ratios (nursing hours/recommended nursing hours based on patient dependency categories) were pooled for the first shift, 24 h, and 7 days of admission for each infant. Patient data were obtained from the Canadian Neonatal Network database. Primary outcome was mortality and/or morbidity (severe neurological injury, bronchopulmonary dysplasia, necrotizing enterocolitis, and late-onset sepsis, severe retinopathy of prematurity). Adjusted odds ratios (AOR) for association of exposure with outcomes were estimated using generalized linear mixed models with a random effect for center, while adjusting for confounders (gestational age, small for gestational age, sex, outborn, Score for Neonatal Acute Physiology version 2, mode of delivery, and the other organizational variables).
Results
Among 1870 infants included in analyses, 796 (43%) had mortality/morbidity. Median occupancy was 89% (IQR 82-94) and median nursing provision was 1.13 (IQR 0.97-1.37). Overall higher NICU occupancy on shift of admission, first 24 h, and 7 days were associated with higher odds of mortality/morbidity (Figure 1) but nursing provision was not (Figure 2). Subgroup analysis by GA (< 29 and 29-32 weeks) yielded similar results (not shown). Generalized linear mixed model analyses showed that a 5% reduction in occupancy in the first 24 h of admission was associated with a 6% reduction in mortality/morbidity.
Conclusion
NICU occupancy is associated with mortality/morbidity among very preterm infants and may reflect lack of adequate resources in periods of high activity. Interventions aimed at reducing occupancy and maintaining adequate resources need to be considered as strategies to improve patient outcomes.

Abstract
Primary Subject area
Neonatal-Perinatal Medicine
Background
Mechanical ventilation is frequently used in preterm infants for various indications, but is associated with multiple complications, including bronchopulmonary dysplasia and poorer neurodevelopmental outcomes. Noninvasive high-frequency oscillatory ventilation (nHFOV) is a noninvasive ventilation (NIV) strategy used to avoid mechanical ventilation and associated complications. However, its effectiveness remains controversial, and its safety has not been established.
Objectives
The objectives were to evaluate the effectiveness of nHFOV to prevent intubations and support adequate ventilation in preterm infants, and to assess its safety profile.
Design/Methods
This was a retrospective crossover case study including 24 infants and 30 nHFOV instances between May 2018 and June 2020. Infants were included if they were placed on nHFOV for at least one hour; each nHFOV trial contributed as one instance. Data was collected from health records. Effectiveness outcomes were: successful transition to another NIV mode without requiring intubation, and variations in CO2, FiO2, and number of spells. Safety outcomes were: apparition of intraventricular hemorrhage (IVH), gastrointestinal complications, nasal cutaneous trauma, and comfort as assessed with the Neonatal Pain, Agitation and Sedation Scale (N-PASS). Descriptive statistics were used for baseline characteristics. Nonparametric and semiparametric tests were used to compare outcomes pre- and during nHFOV.
Results
Baseline characteristics are presented in Table 1. At initiation of nHFOV, mean chronological age and weight were 24 days (95% CI: 20 – 28) and 1119 grams (95% CI: 1038 – 1200) respectively. The most frequent indication for nHFOV was spells (56.7%), and the mean duration of nHFOV instances was 3.9 days (95% CI: 2.7 – 5.1) (Table 1). In 18 (60%) cases, infants transitioned successfully to another NIV mode without requiring intubation. Levels of CO2 and number of spells were significantly lower during nHFOV than pre-nHFOV. There was no significant difference in FiO2 pre-nHFOV and during nHFOV. No apparition or progression of IVH was observed following the use of nHFOV. There was no significant difference in N-PASS, nasal trauma, and gastrointestinal complications pre-nHFOV and during nHFOV (Table 2).
Conclusion
This study suggests that nHFOV is an effective ventilation method to avoid intubation and to decrease spells in preterm infants, without increasing complications.

Neurodevelopmental outcomes of preterm infants conceived by assisted reproductive technology. Am J Obstet Gynecol 2021; 225:276.e1-276.e9. [PMID: 33798481 DOI: 10.1016/j.ajog.2021.03.027] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 03/16/2021] [Accepted: 03/26/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND There have been concerns about the development of children conceived through assisted reproductive technology. Despite multiple studies investigating the outcomes of assisted conception, data focusing specifically on the neurodevelopmental outcomes of infants conceived through assisted reproductive technology and born preterm are limited. OBJECTIVE This study aimed to evaluate and compare the neurodevelopmental outcomes of preterm infants born at <29 weeks' gestation at 18 to 24 months' corrected age who were conceived through assisted reproductive technology and those who were conceived naturally. STUDY DESIGN This retrospective cohort study included inborn, nonanomalous infants, born at <29 weeks' gestation between January 1, 2010, and December 31, 2016, who had a neurodevelopmental assessment at 18 to 24 months' corrected age at any of the 10 Canadian Neonatal Follow-Up Network clinics. The primary outcome was neurodevelopmental impairment at 18 to 24 months, defined as the presence of any of the following: cerebral palsy; Bayley-III cognitive, motor, or language composite score of <85; sensorineural or mixed hearing loss; and unilateral or bilateral visual impairment. Secondary outcomes included mortality, composite of mortality or neurodevelopmental impairment, significant neurodevelopmental impairment, and each component of the primary outcome. We compared outcomes between infants conceived through assisted reproductive technology and those conceived naturally, using bivariate and multivariable analyses after adjustment. RESULTS Of the 4863 eligible neonates, 651 (13.4%) were conceived using assisted reproductive technology. Maternal age; education level; and rates of diabetes mellitus, receipt of antenatal corticosteroids, and cesarean delivery were higher in the assisted reproduction group than the natural conception group. Neonatal morbidity and death rates were similar except for intraventricular hemorrhage, which was lower in the assisted reproduction group (33% [181 of 546] vs 39% [1284 of 3318]; P=.01). Of the 4176 surviving infants, 3386 (81%) had a follow-up outcome at 18 to 24 months' corrected age. Multivariable logistic regression adjusting for gestational age, antenatal steroids, sex, small for gestational age, multiple gestations, mode of delivery, maternal age, maternal education, pregnancy-induced hypertension, maternal diabetes mellitus, and smoking showed that infants conceived through assisted reproduction was associated with lower odds of neurodevelopmental impairment (adjusted odds ratio, 0.67; 95% confidence interval, 0.52-0.86) and the composite of death or neurodevelopmental impairment (adjusted odds ratio, 0.67; 95% confidence interval, 0.54-0.84). Conception through assisted reproductive technology was associated with decreased odds of a Bayley-III composite cognitive score of <85 (adjusted odds ratio, 0.68; 95% confidence interval, 0.48-0.99) and composite language score of <85 (adjusted odds ratio, 0.67; 95% confidence interval, 0.50-0.88). CONCLUSION Compared with natural conception, assisted conception was associated with lower odds of adverse neurodevelopmental outcomes, especially cognitive and language outcomes, at 18 to 24 months' corrected age among preterm infants born at <29 weeks' gestation. Long-term follow-up studies are required to assess the risks of learning disabilities and development of complex visual-spatial and processing skills in these children as they reach school age.

Gestational Age-Dependent Variations in Effects of Prophylactic Indomethacin on Brain Injury and Intestinal Injury. J Pediatr 2021; 235:26-33.e2. [PMID: 33689709 DOI: 10.1016/j.jpeds.2021.02.073] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 02/22/2021] [Accepted: 03/03/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To evaluate the impact of prophylactic indomethacin on early death (<10 days after birth) or severe neurologic injury and on early death or spontaneous intestinal perforation by completed weeks of gestational age in neonates born <29 weeks of gestation. STUDY DESIGN This was a multicenter, retrospective cohort study of neonates (n = 12 515) born at 236/7 weeks of gestational age, admitted to neonatal intensive care units participating in the Canadian Neonatal Network who received prophylactic indomethacin started within the first 12 hours after birth. Univariate and multivariate analysis compared the composite outcomes of early death or severe neurologic injury and early death or spontaneous intestinal perforation. RESULTS Of 12 515 eligible neonates, 1435 (11.5%) were exposed to prophylactic indomethacin; recipients were of lower gestational age and birth weight and had greater severity of illness (Score of Neonatal Acute Physiology with Perinatal Extension) on admission compared with nonrecipients. After we adjusted for confounders, prophylactic indomethacin was associated with reduced odds of early death or severe neurologic injury and early death or spontaneous intestinal perforation in neonates born at 23-24 weeks of gestational age. However, prophylactic indomethacin was associated with increased odds of early mortality or spontaneous intestinal perforation for neonates born at 26-28 weeks of gestational age. CONCLUSIONS Prophylactic indomethacin use was associated with benefit in neonates born at 23-24 weeks of gestational age, but with harm at 26-28 weeks of gestational age. Given the observation of significantly improved survival, a randomized controlled trial is needed to investigate the effect of prophylactic indomethacin in babies born at 23-25 weeks of gestational age.

Abstract
Acquired brain injury remains common in very preterm infants and is associated with significant risks for short- and long-term morbidities. Cranial ultrasound has been widely adopted as the first-line neuroimaging modality to study the neonatal brain. It can reliably detect clinically significant abnormalities that include germinal matrix and intraventricular hemorrhage, periventricular hemorrhagic infarction, post-hemorrhagic ventricular dilatation, cerebellar hemorrhage, and white matter injury. The purpose of this article is to provide a consensus approach for detecting and classifying preterm brain injury to reduce variability in diagnosis and classification between neonatologists and radiologists. Our overarching goal with this work was to achieve homogeneity between different neonatal intensive care units across a large country (Canada) with regards to classification, timing of brain injury screening and frequency of follow up imaging. We propose an algorithmic approach that can help stratify different grades of germinal matrix-intraventricular hemorrhage, white matter injury, and ventricular dilatation in very preterm infants.

Abstract
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.

Abstract
BACKGROUND Preterm birth is the leading cause of morbidity and mortality in children younger than 5 years. We report the changes in neonatal outcomes and care practices among very preterm infants in Canada over 14 years within a national, collaborative, continuous quality-improvement program. METHODS We retrospectively studied infants born at 23-32 weeks' gestation who were admitted to tertiary neonatal intensive care units that participated in the Evidence-based Practice for Improving Quality program in the Canadian Neonatal Network from 2004 to 2017. The primary outcome was survival without major morbidity during the initial hospital admission. We quantified changes using process-control charts in 6-month intervals to identify special-cause variations, adjusted regression models for yearly changes, and interrupted time series analyses. RESULTS The final study population included 50 831 infants. As a result of practice changes, survival without major morbidity increased significantly (56.6% [669/1183] to 70.9% [1424/2009]; adjusted odds ratio [OR] 1.08, 95% confidence interval [CI] 1.06-1.10, per year) across all gestational ages. Survival of infants born at 23-25 weeks' gestation increased (70.8% [97/137] to 74.5% [219/294]; adjusted OR 1.03, 95% CI 1.02-1.05, per year). Changes in care practices included increased use of antenatal steroids (83.6% [904/1081] to 88.1% [1747/1983]), increased rates of normothermia at admission (44.8% [520/1160] to 67.5% [1316/1951]) and reduced use of pulmonary surfactant (52.8% [625/1183] to 42.7% [857/2009]). INTERPRETATION Network-wide quality-improvement activities that include better implementation of optimal care practices can yield sustained improvement in survival without morbidity in very preterm infants.

Abstract
BACKGROUND Nasal continuous positive airway pressure (NCPAP) is a well-studied treatment for respiratory problems in preterm infants. However, the best strategy for NCPAP weaning is unknown. OBJECTIVE We aimed to compare the success of progressive pressure wean versus sudden wean for discontinuation of NCPAP in preterm infants. METHODS We conducted a systematic review and meta-analysis of publications identified by searching MEDLINE, Embase, -CINAHL, and CENTRAL. Randomized controlled trials comparing pressure wean to sudden wean for NCPAP in preterm infants were included. Primary outcomes were postmenstrual age (PMA) at successful weaning and weight gain. Secondary outcomes were total duration of ventilation, success of weaning strategy on first attempt, length of stay (LOS), and bronchopulmonary dysplasia (BPD). RESULTS Two trials (422 infants) were eligible for inclusion. Pressure wean was associated with a higher PMA at weaning (33.9 ± 2.1 vs. 32.1 ± 2.0 weeks, mean difference [MD] 0.88, 95% CI 0.40 to 1.35, low quality evidence). Daily weight gain was only reported in 1 trial. Total duration of ventilation was not reported. Pressure wean was associated with higher probability of successful weaning at first attempt (risk ratio [RR] 1.25, 95% CI 1.03-1.53). However, it was not associated with LOS (MD -2.5 days, 95% CI -7.3 to 2.4) or BPD (RR 0.92, 95% CI 0.52-1.63). CONCLUSION Sudden wean of NCPAP was associated with a lower PMA at successful wean compared to pressure wean but also with a lower rate of successful wean at first attempt, most likely because of the developmental stage at which weaning is possible.

Abstract
BACKGROUND Persistent pulmonary hypertension of the newborn (PPHN) occurs in 10% of neonatal respiratory insufficiency. To selectively reduce pulmonary vascular resistance, several treatments have been tried. Inhaled epoprostenol (iPGI2) has been used for 12 years in our institution for the management of refractory PPHN despite the gaps in the literature to support this use. OBJECTIVES The primary objective was to evaluate the efficacy of iPGI2 for PPHN. The secondary objectives were to describe its use in neonates and assess side effects. STUDY DESIGN This retrospective cohort study included infants < 28 days with PPHN treated with iPGI2 in the neonatal or pediatric intensive care units of our institution between 2004 and 2016. RESULTS We reviewed 43 patient' care episodes (mean gestational age of 36 weeks). This was an extremely ill population with 54% mortality rate. Oxygenation index improved significantly after 12-hour treatment (p = 0.047), with a rebound effect when discontinuing nebulization. By the end of the therapy, the fraction of inspired oxygen had significantly dropped (p = 0.0018). Echocardiographic markers tended to normalize during treatment. No potential side effects were reported. CONCLUSION In these sick newborns, we observed an improvement in PPHN under iPGI2 without significant adverse effects. To our knowledge, this is the largest neonatal cohort reported to have received iPGI2 for PPHN.
