Abstract
OBJECTIVES To investigate the variability in diagnostic and therapeutic approaches to posthemorrhagic ventricular dilatation (PHVD) among Canadian neonatal centers, and secondary exploration of differences in approaches between Canadian and European practices. METHODS We conducted a survey among Canadian tertiary neonatal centers on their local practices for managing very preterm infants with PHVD. The survey covered questions on the diagnostic criteria, timing and type of interventions and resources utilization (transfer to neurosurgical sites and neurodevelopmental follow-up). In a secondary exploration, Canadian responses were compared with responses to the same survey from European centers. RESULTS 23/30 Canadian centers (77%) completed the survey. There was no consensus among Canadian centers on the criteria used for diagnosing PHVD or to initiate intervention. The therapeutic interventions also vary, both for temporizing procedures or permanent shunting. Compared to European practices, the Canadian approach relied less on the sole use of ultrasound criteria for diagnosing PHVD (43 vs 94%, p < 0.0001) or timing intervention (26 vs 63%, p = 0.007). Majority of European centers intervened early in the development of PHVD based on ultrasound parameters, whereas Canadian centers intervened based on clinical hydrocephalus, with fewer centers performing serial lumbar punctures prior to neurosurgical procedures (40 vs 81%, p = 0.003). CONCLUSION Considerable variability exists in diagnosis and management of PHVD in preterm infants among Canadian tertiary centers and between Canadian and European practices. Given the potential implications of the inter-center practice variability on the short- and long-term outcomes of preterm infants with PHVD, efforts towards evidence-based Canada-wide practice standardization are underway.

Zhao Y, Zhang W, Tian X. Analysis of risk factors of early intraventricular hemorrhage in very-low-birth-weight premature infants: a single center retrospective study. BMC Pregnancy Childbirth 2022; 22:890. [PMID: 36456995 PMCID: PMC9713978 DOI: 10.1186/s12884-022-05245-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Accepted: 11/25/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND This study aimed to determine the risk factors of early intraventricular hemorrhage (IVH) in very-low-birth-weight (VLBW) premature infants in China to guide early interventions and improve the survival and quality of life of these infants. METHODS Data on 421 VLBW premature infants admitted to the neonatal intensive care unit of Tianjin Central Hospital of Gynecology Obstetrics between July 2017 and July 2019 were retrospectively evaluated. Data on head ultrasound results, maternal pregnancy complications, and perinatal conditions were reviewed to evaluate the association between maternal and neonatal factors and the development and severity of IVH. RESULTS Univariate analysis showed that the incidence of early IVH was significantly higher in neonates with early gestational age, delivered after spontaneous labor, low birth weight, 5-minute Apgar score ≤ 7, invasive mechanical ventilation, and early onset sepsis (χ2 = 11.087, 16.868, 4.779, 11.170, 6.655, and 6.260, respectively; P < 0.05), but it was significantly lower in the presence of gestational hypertension (χ2 = 4.373, P = 0.037). In addition, severe IVH was significantly associated with early gestational age, low birth weight, 5-minute Apgar score ≤ 7, and neonatal sepsis (χ2 = 11.599, 8.263, 11.172, and 7.749, respectively; P < 0.05). Logistic regression analysis showed that antenatal glucocorticoid use was associated with significantly reduced incidence of severe IVH (OR = 0.095, 95% CI = 0.012-0.739, P = 0.024). CONCLUSION Appropriate mode of delivery may effectively reduce the incidence of IVH in VLBW premature infants. The antenatal glucocorticoid use may also protect against severe IVH. The focus on steroid prophylaxis, mode of delivery and prevention of perinatal asphyxia should be stressed in China.

Abstract
OBJECTIVE To develop a head ultrasound (HUS) screening protocol for infants born <32 weeks gestational age (GA) that accurately identifies severe brain injury (SBI) while minimizing resource use. STUDY DESIGN Retrospective cohort study of infants born <32 weeks GA, admitted to a level 3 neonatal intensive care unit between 2011 and 2017. Timing and results of each HUS were reviewed. SBI was defined as intraventricular hemorrhage grade ≥3 and/or periventricular leukomalacia. Logistic regression models were used to identify risk factors and evaluate the predictive value of HUS at different time points during hospitalization. RESULTS Of 651 included infants, 71 (11%) developed SBI. Risk factors for SBI were GA at birth <29 weeks (adjusted odds ratio (aOR) 2.87, 95% confidence interval (CI) 1.50-5.48), vasopressors on admission (aOR 3.08, 95%CI 1.38-6.88) and mechanical ventilation on admission (aOR 2.50, 95%CI 1.33-4.68). Infants were classified into three risk groups based on these risk factors, and combinations of 1-5 HUS time points were evaluated to determine the optimal number and timing of HUS for each group. The optimal number of screening HUS ranged from 1 for low-risk to 2 for high-risk infants. Adopting a screening protocol using the number and timing of HUS optimized by risk group could reduce the total number of HUS performed by 40% and the median number of HUS per infant from 3 (IQR 2-4) to 2 (IQR 1-3) (p < .01). CONCLUSIONS Implementation of a risk factor-based HUS screening protocol can help reduce resource use while maintaining high sensitivity for detecting SBI.

Abstract
Prematurity is a common risk factor in children, affecting approximately 10% of live births, globally. It is more common in children with critical congenital heart disease (CCHD) and carries important implications in this group of patients. While outcomes have been improving over the years, even late preterm birth is associated with worse outcomes in children born with critical congenital heart disease compared to those without. Infants with both prematurity and CCHD are at particularly high risk for important comorbidities, including: necrotizing enterocolitis, intraventricular hemorrhage, white matter injury, neurodevelopmental anomalies and retinopathy of prematurity. Lesion-specific intensive care management of these infants, interventional and peri-operative management specifically tailored to their needs, and multidisciplinary care all have the potential to improve outcomes in this challenging group.

Abstract
Increasing numbers of neonatal intensive care units have formed small baby units or small baby teams with the intention to optimize care of extremely premature infants. Considerable time, energy, and resources are required to develop and sustain complex quality improvement constructs, so legitimate questions about effectiveness, unintended consequences, and lost opportunity costs warrant scrutiny. The small baby unit literature is diminutive. Errors of chance, bias, and confounding secondary to insufficient definitions of process and outcome metrics, overlapping quality improvement projects, and limited cost analyses restrict firm conclusions. Well-established quality improvement methodologies such as evidence-based guidelines, standardized variability reduction using measurement-and-adjust techniques, family-integrated focus, and developmentally sensitive care, reliably improve outcomes for all-sized premature infants. There is not compelling published evidence that adding specialized small baby units or designated teams for extremely premature infants further enhances short- or long-term health if robust quality improvement fundamentals are already imbedded within local culture.

Abstract
INTRODUCTION Very preterm infants are at high risk of early death or severe brain injury, with potential for impaired long-term neurodevelopmental function and physical health. There are evidence-based healthcare practices that can reduce the incidence. MATERIALS AND METHODS Infants born at 24-316 weeks gestational age and admitted within 24 h to NICUs participating in the Chinese Neonatal Network in 2019 were included. We examined the association between 4 evidence-based practices: inborn (born in a tertiary hospital in the Chinese Neonatal Network), ACS (any antenatal corticosteroid), MgSO4 (prenatal magnesium sulfate), and NT (normothermic temperature [36.0-37.5°C] at admission) and early death and/or severe brain injury in the study population. RESULTS Of 6,035 eligible infants, the incidence of early death and/or severe brain injury was 10.6%. Exposure to ACS only was associated with significant lower incidence of death and/or severe brain injury than none (aOR, 0.71; 95% CI: 0.57-0.88), but not MgSO4 only (aOR, 0.97; 95% CI: 0.81-1.17), NT only (aOR, 0.91; 95% CI: 0.76-1.08), or inborn only (aOR, 0.91; 95% CI: 0.72-1.15). The association between number of practices and incidence of early death and/or severe brain injury is as follows: none = 23% (31/138), any 1 = 14% (84/592), any 2 = 12% (185/1,538), any 3 = 9% (202/2,285), and all 4 = 9% (140/1,482). DISCUSSION/CONCLUSION More comprehensive use of evidence-based practices was associated with improved survival without severe brain injury among very preterm infants born at <32 weeks gestational age.

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
AIM To describe how Canadian level III neonatal intensive care units (NICU) organise mortality and morbidity rounds (M&MR) and explore clinicians' perspectives. METHODS This questionnaire study, including open-ended questions, examined the following domains: (1) M&MR format, (2) ethical issues and (3) limitations and perceived effectiveness. RESULTS Sixteen out of twenty (80%) level III NICUs participated. All deaths and 64% of morbidities were discussed. M&MR occurred monthly (69%) with 3-5 patients discussed hourly (63%) and usually (75%) physician led. Wide variations of practice between centres existed for practical issues, such as administrative support and attendance. 44% of centres allowed nurses to participate. Goals reported by participants were also heterogeneous: reducing medical error (56%), educational (50%), improving communication (44%) and peer review (23%). Practical barriers were time (75%) and lack of resources/structure (25%). Four main themes were as follows: the role of M&MR, the ongoing blame culture, communication issues and the distinction between mortality and morbidity. CONCLUSION Goals and format of M&MR vary widely. M&MR remains physician-centric, where the blame culture still endures. Neonatal M&MR models should be adapted to the modern NICU to ensure the M&MR stays relevant. It could also benefit from lessons learned in quality improvement.

Abstract
Sterile intra-amniotic inflammation is a clinical condition frequently observed in women with preterm labor and birth, the leading cause of neonatal morbidity and mortality worldwide. Growing evidence suggests that alarmins found in amniotic fluid, such as interleukin (IL)-1α, are central initiators of sterile intra-amniotic inflammation. However, the causal link between elevated intra-amniotic concentrations of IL-1α and preterm birth has yet to be established. Herein, using an animal model of ultrasound-guided intra-amniotic injection of IL-1α, we show that elevated concentrations of IL-1α cause preterm birth and neonatal mortality. Additionally, using immunoblotting techniques and a specific immunoassay, we report that the intra-amniotic administration of IL-1α induces activation of the NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome in the fetal membranes, but not in the decidua, as evidenced by a concomitant increase in the protein levels of NLRP3, active caspase-1, and IL-1β. Lastly, using Nlrp3-/- mice, we demonstrate that the deficiency of this inflammasome sensor molecule reduces the rates of preterm birth and neonatal mortality caused by the intra-amniotic injection of IL-1α. Collectively, these results demonstrate a causal link between elevated IL-1α concentrations in the amniotic cavity and preterm birth as well as adverse neonatal outcomes, a pathological process that is mediated by the NLRP3 inflammasome. These findings shed light on the mechanisms underlying sterile intra-amniotic inflammation and provide further evidence that this clinical condition can potentially be treated by targeting the NLRP3 inflammasome.

Abstract
INTRODUCTION Untreated twin-to-twin transfusion syndrome (TTTS) is associated with a high risk of perinatal mortality and morbidity. Laser surgery is recommended before 26 weeks of gestation. However, the optimal management in case of late TTTS (occurring after 26 weeks of gestation) is yet to be established. MATERIAL AND METHODS We conducted a systematic review and meta-analysis to evaluate the outcomes of monochorionic-diamniotic twin pregnancies complicated by late TTTS according to different management options (expectant, laser therapy, amnioreduction, or delivery). The primary outcome was mortality, including single and double intrauterine, neonatal, and perinatal death. Secondary outcomes were composite morbidity, neuromorbidity, respiratory distress syndrome, admission to neonatal intensive care unit, intact survival (ie, free from neurological complications), and preterm birth before <32 weeks of gestation. Outcomes were reviewed according to the management and reported for the overall population of twins and disease status (ie, donor and recipient separately). Random-effect meta-analyses of proportions were used to analyze the data. RESULTS Nine studies including 796 twin pregnancies affected by TTTS were included. No randomized controlled trials were available for inclusion. TTTS occurred at ≥26 weeks of gestation in 8.7% (95% CI 6.9%-10.9%; 67/769) of cases reporting TTTS at all gestations. Intrauterine death occurred in 17.7% (95% CI 4.9%-36.2%) of pregnancies managed expectantly, 5.3% (95% CI 0.9%-12.9%) of pregnancies treated with laser, and 0% (95% CI 0%-9%) after amnioreduction. Neonatal death occurred in 42.5% (95% CI 17.5%-69.7%) of pregnancies managed expectantly, in 2.8% (95% CI 0.3%-7.7%) of cases treated with laser, and in 20.2% (95% CI 6%-40%) after amnioreduction. Only one study (10 cases) reported data on immediate delivery after diagnosis with no perinatal deaths. Perinatal death incidence was 55.7% (95% CI 31.4%-78.6%) in twin pregnancies managed expectantly, 5.6% (95% CI 0.5%-15.3%) in those treated with laser, and 20.2% (95% CI 6%-40%) in those after amnioreduction. Intact survival was reported in 44.4%, 96.4%, and 78% of fetuses managed expectantly, with laser or amnioreduction, respectively. CONCLUSIONS Evidence regarding perinatal mortality and morbidity in twin pregnancies complicated by late TTTS according to the different managements was of very low quality. Therefore further high-quality research in this field is needed to elucidate the optimal management of these pregnancies.

Abstract
BACKGROUND There is widespread, increasing use of magnesium sulphate in obstetric practice for pre-eclampsia, eclampsia, and preterm fetal neuroprotection; benefit for preventing preterm labour and birth (tocolysis) is unproven. We conducted a systematic review and meta-analysis to assess whether antenatal magnesium sulphate is associated with unintended adverse neonatal outcomes. METHODS AND FINDINGS CINAHL, Cochrane Library, LILACS, MEDLINE, Embase, TOXLINE, and Web of Science, were searched (inceptions to 3 September 2019). Randomised, quasi-randomised, and non-randomised trials, cohort and case-control studies, and case reports assessing antenatal magnesium sulphate for pre-eclampsia, eclampsia, fetal neuroprotection, or tocolysis, compared with placebo/no treatment or a different magnesium sulphate regimen, were included. The primary outcome was perinatal death. Secondary outcomes included pre-specified and non-pre-specified adverse neonatal outcomes. Two reviewers screened 5,890 articles, extracted data, and assessed risk of bias following Cochrane Handbook and RTI Item Bank guidance. For randomised trials, pooled risk ratios (RRs) or mean differences, with 95% confidence intervals (CIs), were calculated using fixed- or random-effects meta-analysis. Non-randomised data were tabulated and narratively summarised. We included 197 studies (40 randomised trials, 138 non-randomised studies, and 19 case reports), of mixed quality. The 40 trials (randomising 19,265 women and their babies) were conducted from 1987 to 2018 across high- (16 trials) and low/middle-income countries (23 trials) (1 mixed). Indications included pre-eclampsia/eclampsia (24 trials), fetal neuroprotection (7 trials), and tocolysis (9 trials); 18 trials compared magnesium sulphate with placebo/no treatment, and 22 compared different regimens. For perinatal death, no clear difference in randomised trials was observed between magnesium sulphate and placebo/no treatment (RR 1.01; 95% CI 0.92 to 1.10; 8 trials, 13,654 babies), nor between regimens. Eleven of 138 non-randomised studies reported on perinatal death. Only 1 cohort (127 babies; moderate to high risk of bias) observed an increased risk of perinatal death with >48 versus ≤48 grams magnesium sulphate exposure for tocolysis. No clear secondary adverse neonatal outcomes were observed in randomised trials, and a very limited number of possible adverse outcomes warranting further consideration were identified in non-randomised studies. Where non-randomised studies observed possible harms, often no or few confounders were controlled for (moderate to high risk of bias), samples were small (200 babies or fewer), and/or results were from subgroup analyses. Limitations include missing data for important outcomes across most studies, heterogeneity of included studies, and inclusion of published data only. CONCLUSIONS Our findings do not support clear associations between antenatal magnesium sulphate for beneficial indications and adverse neonatal outcomes. Further large, high-quality studies (prospective cohorts or individual participant data meta-analyses) assessing specific outcomes, or the impact of regimen, pregnancy, or birth characteristics on these outcomes, would further inform safety recommendations.
