RESUMO
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.

OBJECTIVES: Public health interventions to reduce maternal mortality have largely focused on obstetric causes of death. However, previous studies have noted that non-obstetrics factors, such as motor vehicle accidents, substance overdoses, homicides, and suicides, may account for a large proportion of maternal deaths. The study objective was to examine trends in maternal deaths from non-obstetric causes across races in the United States (US). METHODS: A population-based cross-sectional study was conducted on 80,710,348 live births using data from the "Birth Data" and "Mortality Multiple Cause" files compiled by the Centers for Disease Control and Prevention from 2000 to 2019. The annual incidence of maternal deaths attributed to non-obstetric causes (/100,000 live-births) during pregnancy and up to 42 days postpartum were calculated across racial groups. Then the effects of race on the risk of non-obstetric maternal mortality and temporal changes over the study period were examined using logistic regression models. RESULTS: From 2000 to 2019, a total 7,334 women died during pregnancy, childbirth, and within 42 days postpartum from non-obstetric causes, representing 34.5% (7,334/21,241) of all maternal mortality. Of non-obstetric deaths, 31.3% were caused by transport accidents and 27.3% by accidental poisoning. American Indian women were found to have the highest risk of non-obstetric maternal mortality (OR 2.20,95% CI 1.90-2.56), and 46.1% (176/382) of all deaths among pregnant American Indian women were caused by non-obstetric complications. Risk of non-obstetric maternal mortality increased overall during the 20-year study period, with a greater increase among Black (1.15, 1.13-1.17) and American Indian women (1.17, 1.13-1.21). CONCLUSION: Non-obstetric causes of death have become increasingly prevalent in the US, especially in American Indian women. Novel interventions to address these non-obstetric factors should especially target American Indian women to improve maternal outcomes.

OBJECTIVES: Guillain-Barré syndrome (GBS) is a rare autoimmune disorder that affects the peripheral nervous system. The purpose of our study was to evaluate maternal and fetal/neonatal outcomes among pregnancies complicated by GBS. METHODS: We performed a retrospective cohort study using the Healthcare Cost and Utilization Project - National Inpatient Sample from the United States. ICD-9 codes were used to identify all pregnant women who delivered between 1999 and 2015 and had a diagnosis of GBS. The remaining women without GBS who delivered during that time period constituted the comparison group. The associations between maternal GBS and obstetrical and fetal/neonatal outcomes were evaluated using multivariate logistic regression, while adjusting for the confounding effects of maternal characteristics. RESULTS: Of 13,792,544 births included in our study, 291 were to women with GBS, for an overall incidence of 2.1/100,000 births. A steady increase in maternal GBS was observed over the study period (from 1.26 to 3.8/100,000 births, p=0.02). Further, women with GBS were more likely to have pregnancies complicated by preeclampsia, OR 1.69 (95â¯% CI 1.06-2.69), sepsis, 9.30 (2.33-37.17), postpartum hemorrhage, 1.83 (1.07-3.14), and to require a transfusion, 4.39 (2.39-8.05). They were also at greater risk of caesarean delivery, 2.07 (1.58-2.72) and increased length of hospital stay, 4.48 (3.00-6.69). Newborns of women with GBS were more likely to be growth restricted, 2.50 (1.48-4.23). CONCLUSIONS: GBS in pregnancy is associated with maternal and newborn adverse outcomes. These patients would benefit from close follow-up throughout their pregnancy and in the postpartum period.
RESUMO
PURPOSE: In the United States (US), deaths during pregnancy and childbirth have increased over the past 2 decades compared to other high-income countries, and there have been reports that racial disparities in maternal mortality have widened. The study objective was to examine recent trends in maternal mortality in the US by race. METHODS: Our population-based cross-sectional study used data from the Centers for Disease Control and Prevention's 2000-2019 "Birth Data" and "Mortality Multiple Cause" data files from the US to calculate maternal mortality during pregnancy, childbirth, and puerperium across race. Logistic regression models estimated the effects of race on the risk of maternal mortality and examined temporal changes in risk across race. RESULTS: A total of 21,241 women died during pregnancy and childbirth, with 65.5% caused by obstetrical complications and 34.5% by non-obstetrical causes. Black women, compared with White women, had greater risk of maternal mortality (OR 2.13, 95% CI 2.06-2.20), as did American Indian women (2.02, 1.83-2.24). Overall maternal mortality risk increased during the 20-year study period, with an annual increase of 2.4 and 4.7/100,000 among Black and American Indian women, respectively. CONCLUSIONS: Between 2000 and 2019, maternal mortality in the US increased, overall and especially in American Indian and Black women. Targeted public health interventions to improve maternal health outcomes should become a priority.

INTRODUCTION: While the literature is replete of clinical studies reporting on the Robin sequence (RS), population-based analyses are scarce with significant variability within the literature in terms of reported incidence, demographic parameters, and outcomes. The authors have conducted a 20-year population-based analysis to guide clinical practice. METHODS: A birth cohort was created from the available datasets in the Healthcare Cost and Utilization Project-Kids' Inpatient Database (HCUP-KID; 2000-2019). Robin sequence patients were identified and further stratified by syndromic status. Incidence, demographic parameters, and outcomes including mortality and tracheostomy rates were computed. A subset analysis comparing the isolated and syndromic cohorts was conducted. Data was analyzed through a χ 2 or t test. RESULTS: The incidence of RS was 5.15:10,000 (95% CI: 4.99-5.31) from a birth cohort of 7.5 million. Overall, 63.3% of the cohort was isolated RS and 36.7% had syndromic RS. Robin sequence patients had a significantly higher rate of cardiac (25.9%) and neurological (8.6%) anomalies compared with the general birth cohort and were most commonly managed in urban teaching hospitals ( P <0.0001). The pooled mortality and tracheostomy rates were 6.6% and 3.6%, respectively. Syndromic status was associated with a longer length of hospital stay (27.8 versus 13.6 d), tracheostomy rate (6.2% versus 2.1%), and mortality (14.1% versus 2.2%) compared with isolated RS ( P <0.0001). CONCLUSIONS: The true incidence of RS is likely higher than previously reported estimates. Isolated RS patients have a low associated mortality and tracheostomy rate and are typically managed in urban teaching hospitals. Syndromic status confers a higher mortality rate, tracheostomy rate, and length of stay compared with nonsyndromic counterparts.

PURPOSE: Amniotic fluid embolism (AFE) is a leading cause of obstetrical cardiac arrest and maternal morbidity. The pathogenesis of hemodynamic collapse is thought to be from right ventricular (RV) failure; however, there is a paucity of data documenting echocardiography findings in this population. We undertook a systematic review of the literature to evaluate the echocardiography findings in patients with AFE. SOURCES: We retrieved all case reports and case series reporting AFE in Embase and MEDLINE from inception to 20 November 2021. Studies reporting AFE diagnosed by fulfilling at least one of three different proposed AFE criteria and echocardiography findings during hospitalization were included. Patient and echocardiographic data were retrieved, and univariate logistic regression analysis was performed for outcomes of interest. Bias was assessed using the Joanna Briggs Institute clinical appraisal tool for case series. PRINCIPAL FINDINGS: Eighty publications reporting on 84 patients were included in the final review. Fifty-five out of 82 patients with data (67%) showed RV dysfunction, including 11/82 (13%) with biventricular dysfunction; 14/82 (17%) had normal systolic function. No data on RV or left ventricular function were reported for two patients. The presence of RV dysfunction on echocardiography was associated with cardiac arrest (odds ratio [OR], 3.66; 95% confidence interval [CI], 1.39 to 9.67; P = 0.009), and a composite risk of cardiac arrest, maternal death or use of extracorporeal membrane oxygenation (OR, 3.86; 95% CI, 1.43 to 10.4; P = 0.007). A low risk of bias was observed in 15/84 (18%) cases. CONCLUSIONS: Right ventricular dysfunction on echocardiography is a common finding in AFE and is associated with a high risk of cardiac arrest. The finding of RV dysfunction on echocardiography may help diagnose AFE and help triage the highest risk patients with AFE. STUDY REGISTRATION: PROSPERO (CRD42021271323); registered 1 September 2021.
RéSUMé: OBJECTIF: L'embolie amniotique (EA) est l'une des principales causes d'arrêt cardiaque obstétrical et de morbidité maternelle. Il est présumé que la pathogenèse du choc hémodynamique provient d'une défaillance ventriculaire droite (VD). Cependant, il y a peu de données documentant les constatations de l'examen échocardiographique dans cette population. Nous avons effectué une revue systématique des données probantes visant à évaluer l'utilité de l'échocardiographie chez les patientes atteintes d'embolie amniotique. SOURCES: Nous avons évalué tous les rapports de cas et séries de cas rapportant une EA dans les bases de données Embase et MEDLINE de leur création jusqu'au 20 novembre 2021. Les études rapportant une EA diagnostiquée en remplissant au moins l'un des trois critères d'EA proposés et les résultats échocardiographiques pendant l'hospitalisation ont été incluses. Les données sur les patientes et échocardiographiques ont été colligées, et une analyse de régression logistique univariée a été effectuée pour les issues cliniques d'intérêt. Le risque de biais a été évalué à l'aide de l'outil d'évaluation clinique de l'Institut Joanna Briggs pour les séries de cas. CONSTATATIONS PRINCIPALES: Quatre-vingts publications incluant 84 patientes ont été incluses dans la revue finale. Cinquante-cinq des 82 patientes présentant des données (67 %) avaient une dysfonction du VD incluant 11/82 (13 %) avec une dysfonction biventriculaire. Quatorze patientes sur 82 (17 %) avaient une fonction systolique normale. Aucune donnée sur la fonction du ventricule droit ou gauche n'a été rapportée pour deux patientes. La présence d'une dysfonction du VD à l'échocardiographie était associée à un arrêt cardiaque (rapport de cotes [RC], 3,66; intervalle de confiance à 95 % [IC], 1,39 à 9,67; P = 0,009), et à un risque composite d'arrêt cardiaque, de décès maternel ou d'utilisation de l'oxygénation par membrane extracorporelle (ECMO) (RC, 3,86; IC 95 %, 1,43 à 10,4; P = 0,007). Un faible risque de biais a été observé dans 15/84 (18 %) des cas. CONCLUSION: La dysfonction ventriculaire droite à l'échocardiographie est une constatation courante dans l'embolie amniotique et est associée à un risque élevé d'arrêt cardiaque. La découverte d'une dysfonction du VD à l'échocardiographie peut aider à diagnostiquer l'embolie amniotique et à identifier les patientes atteintes d'embolie amniotique les plus à risque.

PURPOSE: To identify risk factors associated with bladder injury during cesarean delivery, and to determine the frequency of associated morbidities. METHODS: Data obtained from the United States' Health Care Cost and Utilization Project-Nationwide Inpatient Sample were used to conduct a retrospective population-wide cohort study. ICD-9 codes were used to identify women who underwent a cesarean delivery between 1999 and 2015. Subsequently, women were classified based on whether or not they experienced a bladder injury during delivery. Multivariate logistic regression was used to determine predictors of bladder injury in cesarean deliveries and to examine the associated morbidities while adjusting for baseline maternal demographics and clinical characteristics. RESULTS: Of 4,169,681 cesarean deliveries identified, there were 7,627 (0.2%) bladder injuries for an overall incidence of 18 per 10,000. Women ≥ 35 years were at greater risk of bladder injury 1.5 (1.4-1.6), as were women with endometriosis 2.0 (1.5-2.7) and Crohn's disease 2.7 (1.7-4.2). Risk of bladder injury increased if the cesarean delivery was associated with placenta previa 2.2 (1.9-2.4), previous cesarean delivery 4.3 (4.1-4.6), failed instrumental delivery 4.1 (3.5-4.8), fetal distress 1.7 (1.6-1.8), failed trial of labor after cesarean delivery 1.3 (1.2-1.4), and labor dystocia 1.7 (1.6-1.8). Cesarean hysterectomies presented the greatest risk for bladder injury 37.0 (33.7-40.6). Bladder injury was associated with an increased frequency of sepsis, venous thromboembolism, peritonitis, blood transfusions and longer hospital stays. CONCLUSION: Bladder injury during cesarean deliveries is a rare outcome but it is more common among women with certain demographic and clinical characteristics. Among these cases, strategies to prevent sepsis and venous thromboembolism should be considered.

BACKGROUND: The rate of cesarean delivery has increased in the United States over the last several decades. However, the rate of cesarean delivery on maternal request remains undetermined, and recent data on cesarean delivery on maternal request are lacking. OBJECTIVE: This study aimed to describe the prevalence and temporal trends of cesarean delivery on maternal request in the United States and characterize the population of women who elect to undergo a cesarean delivery in the absence of fetal or maternal indications. Maternal outcomes between women who delivered by cesarean delivery on maternal request and those who did not were compared. STUDY DESIGN: A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 1999 to 2015. An algorithm based on International Classification of Diseases, Ninth Revision codes was created to identify patients who underwent a primary elective cesarean delivery in the absence of fetal or maternal indications. Maternal characteristics and outcomes between women who delivered by cesarean delivery on maternal request and those who did not were compared using descriptive and logistic regression analyses. RESULTS: Of the 13,698,835 deliveries included throughout the study period, 228,586 were identified as cesarean delivery on maternal request. Rates of cesarean delivery on maternal request among all live births increased throughout the study period, from 1% in 1999 to 1.62% in 2015 (P<.0001). Women who delivered by cesarean delivery on maternal request were more likely to be >35 years of age, were in the highest income quartile, and have private insurance. Cesarean delivery on maternal request was associated with an increased risk of venous thromboembolism (odds ratio, 1.9; 95% confidence interval, 1.8-2.0), myocardial infarction (odds ratio, 6.3; 95% confidence interval, 3.8-10.4), sepsis (odds ratio, 5.6; 95% confidence interval, 4.7-6.6), disseminated intravascular coagulation (odds ratio, 2.9; 95% confidence interval, 2.3-3.7), death (odds ratio, 14.5; 95% confidence interval, 11.4-18.6), and prolonged hospital stay (odds ratio, 4.9; 95% confidence interval, 4.8-5.1) and a lower risk of postpartum hemorrhage (odds ratio, 0.7; 95% confidence interval, 0.7-0.7). CONCLUSION: Our findings indicated that cesarean delivery on maternal request accounts for a small but increasing proportion of all cesarean deliveries in the United States. Cesarean delivery on maternal request was more prevalent among women with certain demographic characteristics, indicating that the option of cesarean delivery on maternal request may be more appealing or more frequently offered to a certain population of women. Although the overall risk of adverse events is low for individual births, population effects can result in increased morbidity and mortality. Therefore, the rates of cesarean delivery on maternal request should be monitored on a national level. Study findings were limited by the absence of a specific diagnostic code for cesarean delivery on maternal request.

BACKGROUND: Impaired vascular function is a central feature of pathologic processes preceding the onset of preeclampsia. Arterial stiffness, a composite indicator of vascular health and an important vascular biomarker, has been found to be increased throughout pregnancy in those who develop preeclampsia and at the time of preeclampsia diagnosis. Although sleep-disordered breathing in pregnancy has been associated with increased risk for preeclampsia, it is unknown if sleep-disordered breathing is associated with elevated arterial stiffness in pregnancy. OBJECTIVE: This prospective observational cohort study aimed to evaluate arterial stiffness in pregnant women, with and without sleep-disordered breathing and assess the interaction between arterial stiffness, sleep-disordered breathing, and preeclampsia risk. STUDY DESIGN: Women with high-risk singleton pregnancies were enrolled at 10 to 13 weeks' gestation and completed the Epworth Sleepiness Score, Pittsburgh Sleep Quality Index, and Restless Legs Syndrome questionnaires at each trimester. Sleep-disordered breathing was defined as loud snoring or witnessed apneas (≥3 times per week). Central arterial stiffness (carotid-femoral pulse wave velocity, the gold standard measure of arterial stiffness), peripheral arterial stiffness (carotid-radial pulse wave velocity), wave reflection (augmentation index, time to wave reflection), and hemodynamics (central blood pressures, pulse pressure amplification) were assessed noninvasively using applanation tonometry at recruitment and every 4 weeks from recruitment until delivery. RESULTS: High-risk pregnant women (n=181) were included in the study. Women with sleep-disordered breathing (n=41; 23%) had increased carotid-femoral pulse wave velocity throughout gestation independent of blood pressure and body mass index (P=.042). Differences observed in other vascular measures were not maintained after adjustment for confounders. Excessive daytime sleepiness, defined by Epworth Sleepiness Score >10, was associated with increased carotid-femoral pulse wave velocity only in women with sleep-disordered breathing (Pinteraction=.001). Midgestation (first or second trimester) sleep-disordered breathing was associated with an odds ratio of 3.4 (0.9-12.9) for preeclampsia, which increased to 5.7 (1.1-26.0) in women with sleep-disordered breathing and hypersomnolence, whereas late (third-trimester) sleep-disordered breathing was associated with an odds ratio of 8.2 (1.5-39.5) for preeclampsia. CONCLUSION: High-risk pregnant women with midgestational sleep-disordered breathing had greater arterial stiffness throughout gestation than those without. Sleep-disordered breathing at any time during pregnancy was also associated with increased preeclampsia risk, and this effect was amplified by hypersomnolence.

OBJECTIVES: Acute pancreatitis is a rare condition that can be associated with significant complications. The objective of this study is to evaluate the maternal and newborn outcomes associated with acute pancreatitis in pregnancy. METHODS: A retrospective cohort study using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from the United States was performed. All pregnant patients with acute pancreatitis were identified using International Classification of Disease-9 coding from 1999 to 2015. The effect of acute pancreatitis on maternal and neonatal outcomes in pregnancy was evaluated using multivariate logistic regression, while adjusting for baseline maternal characteristics. RESULTS: From 1999 to 2015, there were a total of 13,815,919 women who gave birth. There were a total of 14,258 admissions of women diagnosed with acute pancreatitis, including 1,756 who delivered during their admission and 12,502 women who were admitted in the antepartum period and did not deliver during the same admission. Acute pancreatitis was associated with increased risk of prematurity, OR 3.78 (95% CI 3.38-4.22), preeclampsia, 3.81(3.33-4.36), postpartum hemorrhage, 1.90(1.55-2.33), maternal death, 9.15(6.05-13.85), and fetal demise, 2.60(1.86-3.62) among women diagnosed with acute pancreatitis. Among women with acute pancreatitis, delivery was associated with increased risk of requiring transfusions, 6.06(4.87-7.54), developing venous thromboembolisms, 2.77(1.83-4.18), acute respiratory failure, 3.66(2.73-4.91), and disseminated intravascular coagulation, 8.12(4.12-16.03). CONCLUSIONS: Acute pancreatitis in pregnancy is associated with severe complications, such as maternal and fetal death. Understanding the risk factors that may lead to these complications can help prevent or minimize them through close fetal and maternal monitoring.

OBJECTIVES: Pregnancy outcomes in women with inflammatory myopathies (IM) are not well studied. The purpose of this study is to evaluate the effects of IM on maternal and neonatal outcomes. METHODS: We conducted a retrospective cohort study using data from the Healthcare Cost and Utilization Project - Nationwide Inpatient Sample (HCUP-NIS) from 1999 to 2015. Among all pregnant women who delivered during this period, those with a diagnosis of IM were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding, which included all patients with dermatomyositis and polymyositis. Maternal and neonatal outcomes were compared in pregnant women with and without IM. Multivariate logistic regression analysis was used to estimate the adjusted effects of IM on these outcomes. RESULTS: A total of 13,792,544 pregnant women delivered between 1999 and 2015, of which 308 had a diagnosis of IM, for an overall prevalence of 2 per 100,000 pregnant women, with rates increasing over the study period. Pregnant women with IM were more likely to be older, African American and suffer from other autoimmune connective tissue diseases. IM in pregnancy was associated with greater risk of preeclampsia, caesarean delivery, major postpartum infections, urinary tract infections and longer hospital stay. Neonates born to mothers with IM had greater risk of prematurity, small for gestational age and intrauterine fetal demise. CONCLUSIONS: Pregnant women with IM are at higher risk of adverse maternal and neonatal outcomes and should be closely followed in specialized centers with collaboration between maternal-fetal medicine and rheumatology.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) may present asymptomatically in a large proportion of cases in endemic areas. Accordingly, universal testing has been suggested as a potential strategy for reducing transmission in the obstetrical setting. We describe the clinical characteristics of patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy at a designated COVID-19 hospitalization centre in Montréal, Québec. METHODS: A single-centre retrospective cohort was constructed to include all pregnant patients who tested positive for SARS-CoV-2 between March 22 and July 31, 2020, and received care at the Jewish General Hospital. Initially, testing was restricted to at-risk patients, identified through the use of a screening questionnaire. Beginning on May 15, 2020, universal testing was implemented, and all pregnant patients admitted to the hospital were tested. Data were collected through chart review. RESULTS: Of 803 patients tested for SARS-CoV-2 during the study period, 41 (5%) tested positive. Among those patients who were symptomatic, the most commonly reported symptoms were cough (53%), fever (37%), dyspnea (30%), and anosmia and/or ageusia (20%). Before the implementation of universal testing, 13% (3 of 24) of patients with SARS-CoV-2 were asymptomatic. After implementation of universal testing, 80% (8 of 10) of patients with SARS-CoV-2 were asymptomatic. CONCLUSION: Our findings suggest that most pregnant patients with SARS-CoV-2 are asymptomatic or have mild symptoms of COVID-19. Particularly in endemic areas, universal testing of pregnant patients presenting to the hospital should be strongly considered as an important measure to prevent in-hospital and community transmission of COVID-19.

OBJECTIVE: Early subchorionic hemorrhage may lead to a disruption in the placental-uterine matrix, which may result in an adherence of the placenta to the endometrium. We evaluated the effect of a first-trimester bleed on the need for a post-vaginal delivery dilatation and curettage (D&C) for removal of retained placenta. METHODS: We conducted a case-control study at a tertiary care centre between 2012 and 2016. Patients identified through medical records as having required a post-vaginal delivery D&C for retained placenta were considered cases and were matched 1:5 with patients delivering vaginally within 1 week who did not require a D&C. History of first-trimester bleeding and subchorionic hemorrhage were identified through chart review. Conditional logistic regression analyses estimated the effect of a first-trimester bleed on the requirement for D&C for retained placenta. Models were adjusted for maternal age and previous uterine surgery. RESULTS: There were 68 cases of retained placenta requiring D&C, for an estimated 3 in 1000 deliveries. Patients requiring D&C were slightly older than controls but were otherwise comparable with respect to baseline demographic characteristics. In adjusted analyses, patients who required a postpartum D&C were more likely than controls to have had a first-trimester bleed at 11.8% and 0.6%, respectively (OR 25.3; 95% CI 4.7-135.4, P < 0.001). Postpartum D&C for retained placenta was associated with postpartum hemorrhage, need for blood transfusion, and manual removal of placenta. CONCLUSION: First-trimester bleeding should be considered a high-risk determinant for post-vaginal delivery D&C for retained placenta and for severe postpartum hemorrhage.

We report on the perinatal outcomes of pregnant patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from 2 hospitals in Montréal, Québec. Outcomes of 45 patients with SARS-CoV-2 during pregnancy were compared with those of 225 patients without infection. Sixteen percent of patients with SARS-CoV-2 delivered preterm, compared with 9% of patients without (Pâ¯=â¯0.28). Median gestational age at delivery (39.3 (interquartile range [IQR] 37.7-40.4) wk vs. 39.1 [IQR 38.3-40.1] wk) and median birth weight (3250 [IQR 2780-3530] g vs. 3340 [IQR 3025-3665] g) were similar between groups. The rate of cesarean delivery was 29% for patients with SARS-CoV-2. Therefore, we did not find important differences in outcomes associated with SARS-CoV-2. Our findings may be limited to women with mild COVID-19 diagnosed in the third trimester.

OBJECTIVES: Obstructive sleep apnea (OSA) is linked to many health comorbidities. We aimed to ascertain if OSA correlates with a rise in poor obstetrical outcomes. METHODS: Employing the United States' Healthcare Cost and Utilization Project - National Inpatient Sample, we performed our retrospective cohort study including all women who delivered between 2006 and 2015. ICD-9 codes were used to characterize women as having a diagnosis of OSA. Temporal trends in pregnancies with OSA were studied, baseline features were evaluated among gravidities in the presence and absence of OSA, and multivariate logistic regression analysis was utilized in assessing consequences of OSA on patient and newborn outcomes. RESULTS: Of a total 7,907,139 deliveries, 3,115 belonged to patients suffering from OSA, resulting in a prevalence of 39 per 100,000 deliveries. Rates rose from 10.14 to 78.12 per 100,000 deliveries during the study interval (p<0.0001). Patients diagnosed with OSA were at higher risk of having pregnancies with preeclampsia, OR 2.2 (95% CI 2.0-2.4), eclampsia, 4.1 (2.4-7.0), chorioamnionitis, 1.4 (1.2-1.8), postpartum hemorrhage, 1.4 (1.2-1.7), venous thromboembolisms, 2.7 (2.1-3.4), and to deliver by caesarean section, 2.1 (1.9-2.3). Cardiovascular and respiratory complications were also more common among these women, as was maternal death, 4.2 (2.2-8.0). Newborns of OSA patients were at elevated risk of being premature, 1.3 (1.2-1.5) and having congenital abnormalities, 2.3 (1.7-3.0). CONCLUSIONS: Pregnancies with OSA were linked to an elevated risk of poor maternal and neonatal outcomes. During pregnancy, OSA patients should receive attentive follow-up care in a tertiary hospital.

OBJECTIVES: The effects of lipid metabolism disorders (LMD) on pregnancy outcomes is not well known. The purpose of this study is to evaluate the impact of LMD on maternal and fetal outcomes. METHODS: Using the Healthcare Cost and Utilization Project - National Inpatient Sample from the United States, we carried out a retrospective cohort study of all births between 1999 and 2015 to determine the risks of complications in pregnant women known to have LMDs. All pregnant patients diagnosed with LMDs between 1999 and 2015 were identified using the International Classification of Disease-9 coding, which included all patients with pure hypercholesterolemia, pure hyperglyceridemia, mixed hyperlipidemia, hyperchylomicronemia, and other lipid metabolism disorders. Adjusted effects of LMDs on maternal and newborn outcomes were estimated using unconditional logistic regression analysis. RESULTS: A total of 13,792,544 births were included, 9,666 of which had an underlying diagnosis of LMDs for an overall prevalence of 7.0 per 10,000 births. Women with LMDs were more likely to have pregnancies complicated by diabetes, hypertension, and premature births, and to experience myocardial infarctions, venous thromboembolisms, postpartum hemorrhage, and maternal death. Their infants were at increased risk of congenital anomalies, fetal growth restriction, and fetal demise. CONCLUSIONS: Women with LMDs are at significantly higher risk of adverse maternal and newborn outcomes. Prenatal counselling should take into consideration these risks and antenatal care in specialized centres should be considered.

OBJECTIVES: We estimated the degree to which the association between race and spontaneous recurrent preterm delivery is mediated by the timing of the first prenatal care visit. METHODS: A retrospective population-based cohort study was conducted using the U.S. National Center for Health Statistics Natality Files. We identified 644,576 women with a prior PTB who delivered singleton live neonates between 2011 and 2017. A mediation analysis was conducted using log-binomial regression to evaluate the mediating effect of timing of first prenatal care visit. RESULTS: During the seven-year period, 349,293 (54.2%) White non-Hispanic women, 131,296 (20.4%) Black non-Hispanic women, 132,367 (20.5%) Hispanic women, and 31,620 (4.9%) Other women had a prior preterm delivery. The risk of late prenatal care initiation was higher in Black non-Hispanic women, Hispanic women, and Other women (women of other racial/ethnic backgrounds) compared to White non-Hispanic women, and the risk of preterm delivery was higher in women with late prenatal care initiation. Between 8 and 15% of the association between race and spontaneous recurrent preterm delivery acted through the delayed timing of the first prenatal care visit. CONCLUSIONS: Racial disparities in spontaneous recurrent preterm delivery rates can be partly, but not primarily, attributed to timing of first prenatal care visit.

INTRODUCTION: Cleft palate is amongst the most common birth defect across the world. Although its etiology is multifactorial, including genetic and environmental contributors, the investigators were interested in exploring whether its incidence was changing over time. METHODS: The Nationwide Inpatient Sample database, the largest publically available healthcare database in the United States, was used to identify all primary palatoplasties performed under 2 years of age and births which occurred over a 17-year period from 1999 to 2015. The change in rate of palatoplasties and overall maternal demographics were assessed longitudinally using the chi-squared test. Significance level was set at Pâ<â0.001. RESULTS: A total of 13,808,795 pregnancies were reviewed during the time period, from 1999 to 2015, inclusively. A total of 10,567 primary palatoplasties were performed in that period of time reflecting an overall rate of 7.7 palatoplasties per 10,000 deliveries. Palatoplasty rates decreased across the study period from 9.5 per 10,000 in 1999 to 7.1 per 10,000âdied/delivered pregnancies in 2015 which corresponds to an average compounded year-to-year decrease of 1.76%, Pâ<â0.001. CONCLUSIONS: The rate of primary palatoplasties, as a proxy for the rate of cleft palate prevalence, has been significantly decreasing over the last 2 decades and may represent improvements in early diagnosis in pregnancy, changing genetic or racial demographics, and/or environmental factors such as decreased maternal smoking in the US population. Future research may be directed at better understanding the definitive etiology of this decreasing prevalence of children undergoing primary cleft palate repairs in the United States.

Race/ethnicity is associated with intrauterine growth restriction (IUGR) and small-for-gestational age (SGA) birth. We evaluated the extent to which this association is mediated by adequacy of prenatal care (PNC). A retrospective cohort study was conducted using US National Center for Health Statistics natality files for the years 2011-2017. We performed mediation analyses using a statistical approach that allows for exposure-mediator interaction, and we estimated natural direct effects, natural indirect effects, and proportions mediated. All effects were estimated as risk ratios. Among 23,118,656 singleton live births, the excess risk of IUGR among Black women, Hispanic women, and women of other race/ethnicity as compared with White women was partly mediated by PNC adequacy: 13% of the association between non-Hispanic Black race/ethnicity and IUGR, 12% of the association in Hispanic women, and 10% in other women was attributable to PNC inadequacy. The percentage of excess risk of SGA birth that was mediated was 7% in Black women, 6% in Hispanic women, and 5% in other women. Our findings suggest that PNC adequacy may partly mediate the association between race/ethnicity and fetal growth restriction. In future research, investigators should employ causal mediation frameworks to consider additional factors and mediators that could help us better understand this association.

OBJECTIVE: With the rising trend of postponing motherhood, there has been an increasing rate of infertility. Social fertility preservation offers the potential to overcome this age-related infertility, and many women are turning to the Internet to seek medical information. The aim of this study was to evaluate online information on social fertility preservation. METHODS: This study used five search terms-"egg freezing," "fertility preservation," "social egg freezing," "social fertility preservation," and "oocyte cryopreservation"-to identify the most popular sites as rated by Google. Accuracy of information and quality of websites were rated on the basis of four categories: Silberg's accountability criteria, Abbott's aesthetic criteria, Flesch-Kincaid readability score, and the Canadian Fertility and Andrology Society (CFAS) and the Society of Obstetricians and Gynaecologists of Canada (SOGC) recommendations (Canadian Task Force classification III). RESULTS: Study investigators identified the 21 most used websites. The average Silberg score was 6.57, with 85.7% of websites meeting the criteria for adequate accountability. Only one website (4.8%) did not meet the criteria for appropriate aesthetic appeal. The average Flesch-Kincaid readability score was 11.39, equivalent to a grade 11 reading level, which is significantly higher than the reading level of the general population. A total of 57% of websites contained less than half of the evidence-based recommendations provided in CFAS and SOGC recommendations. CONCLUSION: Online information on social fertility preservation is easily accessible and aesthetically pleasing, but information is not easily readable and does not reflect evidence-based recommendations. Hence, health care professionals must fill the knowledge gaps and adequately counsel their patients to optimize a woman's chance at a successful pregnancy.
