[Maternal mortality due to obstetric haemorrhage in France 2016-2018]. / Mortalité maternelle par hémorragie obstétricale en France 2016­2018.

Between 2016 and 2018, 20 maternal deaths were related to obstetric haemorrhage, excluding haemorrhage in the first trimester of pregnancy, representing a mortality ratio of 0.87 per 100,000 live births (95% CI 0.5 -1.3). Obstetric haemorrhage is the cause of 7.4% of all maternal deaths up to 1 year, 10% of maternal deaths within 42days, and 21% of deaths directly related to pregnancy (direct causes). Between 2001 and 2018, maternal mortality from obstetric haemorrhage has been considerably reduced, from 2.2deaths per 100,000 live births in 2001-2003 to 0.87 in the period presented here. Nevertheless, obstetric haemorrhage is still one of the main direct causes of maternal death, and remains the cause with the highest proportion of deaths considered probably (53%) or possibly (42%) preventable according to the CNEMM's collegial assessment (see chapter 3). The preventable factors reported are related to inadequate content of care in 94% of cases and/or organisation of care in 44% of cases. In this triennium, maternal death due to haemorrhage occurred mainly in the context of caesarean delivery (65% of cases, i.e. 13/20), and mostly in the context of emergency care (12/13). The main causes of obstetric haemorrhage were uterine rupture (6/20) in unscarred uterus or in association with placenta accreta, and surgical injury during the caesarean delivery (5/20). Every maternity hospital, whatever its resources and/or technical facilities, must be able to plan any obstetric haemorrhage situation that threatens the mother's vital prognosis. Intraperitoneal occult haemorrhage following caesarean section and uterine rupture require immediate surgery with the help of skilled surgeon resources with early and appropriate administration of blood products.

Maternal health surveillance panel: a tool for expanding epidemiological surveillance of women's health and its determinants / Painel de vigilância da saúde materna: uma ferramenta para ampliação da vigilância epidemiológica da saúde das mulheres e seus determinantes

ABSTRACT Objective: To present the methodology used in the development of two products for maternal health surveillance and its determinants and discuss their possible uses. Methods: Based on a theoretical model of the determinants of maternal death and databases of Brazilian health information systems, two free products were developed: an interactive panel "surveillance of maternal health" and an educational material "Aparecida: a story about the vulnerability of Brazilian women to maternal death", both available on the website of the Brazilian Obstetric Observatory. Results: More than 30 indicators were calculated for the period 2012-2020, containing information on socioeconomic conditions and access to health services, reproductive planning, prenatal care, delivery care, conditions of birth and maternal mortality and morbidity. The indicators related to severe maternal morbidity in public hospitalizations stand out, calculated for the first time for the country. The panel allows analysis by municipality or aggregated by health region, state, macro-region and country; historical series analysis; and comparisons across locations and with benchmarks. Information quality data are presented and discussed in an integrated manner with the indicators. In the educational material, visualizations with national and international data are presented, aiming to help in the understanding of the determinants of maternal death and facilitate the interpretation of the indicators. Conclusion: It is expected that the two products have the potential to expand epidemiological surveillance of maternal health and its determinants, contributing to the formulation of health policies and actions that promote women's health and reduce maternal mortality.

RESUME Objetivo: Apresentar a metodologia utilizada no desenvolvimento de dois produtos para a vigilância da saúde materna e seus determinantes e discutir as suas possíveis utilizações. Métodos: A partir de modelo teórico dos determinantes do óbito materno e bases de dados dos sistemas de informação em saúde brasileiros, foram desenvolvidos dois produtos gratuitos: um painel interativo denominado "Vigilância da saúde materna" e um material educativo chamado "Aparecida: uma história sobre a vulnerabilidade da mulher brasileira à morte materna", ambos disponíveis no site do Observatório Obstétrico Brasileiro. Resultados: Foram calculados mais de 30 indicadores para o período 2012-2020, contendo informações sobre condições socioeconômicas e de acesso a serviços de saúde, planejamento reprodutivo, assistência pré-natal, assistência ao parto, condições de nascimento e mortalidade e morbidade materna. Destacam-se os indicadores relacionados à morbidade materna grave em internações públicas, calculados pela primeira vez para o país. O painel permite análises por município ou agregadas por região de saúde, unidade da federação, macrorregião e país; análises de série histórica; e comparações entre localidades e com padrões de referência. Dados de qualidade da informação são apresentados e discutidos de forma integrada aos indicadores. No material educativo, visualizações com dados nacionais e internacionais são apresentadas, visando auxiliar na compreensão dos determinantes do óbito materno e facilitar a interpretação dos indicadores. Conclusão: Espera-se que os produtos tenham o potencial de ampliar a vigilância epidemiológica da saúde materna e seus determinantes, contribuindo para a formulação de políticas e ações de saúde que promovam a saúde das mulheres e reduzam a mortalidade materna.

Nationwide study of in-hospital maternal mortality in Ecuador, 2015-2022 / Estudio a nivel nacional de la mortalidad materna intrahospitalaria en Ecuador, 2015-2022 / Estudo nacional sobre mortalidade materna intra-hospitalar no Equador, 2015-2022

ABSTRACT Objective. This study aimed to analyze estimates of in-hospital delivery-related maternal mortality and sociodemographic factors influencing this mortality in Ecuador during 2015 to 2022. Methods. Data from publicly accessible registries from the Ecuadorian National Institute of Statistics and Censuses were analyzed. Maternal mortality ratios (MMRs) were calculated, and bivariate and multivariate logistic regression models were used to obtain unadjusted and adjusted odds ratios. Results. There was an increase in in-hospital delivery-related maternal deaths in Ecuador from 2015 to 2022: MMRs increased from 3.70 maternal deaths/100 000 live births in 2015 to 32.22 in 2020 and 18.94 in 2022. Manabí province had the highest rate, at 84.85 maternal deaths/100 000 live births between 2015 and 2022. Women from ethnic minorities had a higher probability of in-hospital delivery-related mortality, with an adjusted odds ratio (AOR) of 9.59 (95% confidence interval [95% CI]: 6.98 to 13.18). More maternal deaths were also observed in private health care facilities (AOR: 1.99, 95% CI: 1.4 to 2.84). Conclusions. Efforts to reduce maternal mortality have stagnated in recent years. During the COVID-19 pandemic in 2020, an increase in maternal deaths in hospital settings was observed in Ecuador. Although the pandemic might have contributed to the stagnation of maternal mortality estimates, socioeconomic, demographic and clinical factors play key roles in the complexity of trends in maternal mortality. The results from this study emphasize the importance of addressing not only the medical aspects of care but also the social determinants of health and disparities in the health care system.

RESUMEN Objetivo. El objetivo de este estudio fue analizar las cifras estimadas de mortalidad materna intrahospitalaria asociada al parto y los factores sociodemográficos que influyen en ella en Ecuador en el período 2015-2022. Métodos. Se analizaron datos de los registros de acceso público del Instituto Nacional de Estadística y Censos de Ecuador. Se calcularon las razones de mortalidad materna (RMM) y se utilizaron modelos de regresión logística bivariados y multivariados para obtener los cocientes de posibilidades sin ajustar y ajustados. Resultados. Entre el 2015 y el 2022, se observó un aumento de las muertes maternas intrahospitalarias asociadas al parto en Ecuador: la RMM aumentó de 3,70 muertes maternas por 100 000 nacidos vivos en el 2015 a 32,22 en el 2020 y 18,94 en el 2022. En la provincia de Manabí se registró la cifra más alta, con 84,85 muertes maternas por 100 000 nacidos vivos entre el 2015 y el 2022. Las mujeres pertenecientes a minorías étnicas tuvieron una mayor probabilidad de muerte intrahospitalaria por causas relacionadas con el parto, con un cociente de posibilidades ajustado (aOR, por su sigla en inglés) de 9,59 (intervalo de confianza del 95% [IC del 95%]: 6,98 a 13,18). También se observó una mayor mortalidad materna en los establecimientos de salud privados (aOR: 1,99, IC del 95%: 1,4 a 2,84). Conclusiones. Los esfuerzos para reducir la mortalidad materna se han estancado en los últimos años. Durante la pandemia de COVID-19, se observó un aumento de las muertes maternas en el 2020 en entornos hospitalarios en Ecuador. Si bien la pandemia podría haber contribuido a que las cifras estimadas de mortalidad materna se estancaran, los factores socioeconómicos, demográficos y clínicos desempeñan un papel clave en la complejidad de las tendencias de la mortalidad materna. Los resultados de este estudio destacan la importancia de abordar no solo los aspectos médicos de la atención, sino también los determinantes sociales de la salud y las disparidades en el sistema de atención de salud.

RESUMO Objetivo. O objetivo deste estudo foi analisar estimativas de mortalidade materna relacionada ao parto intra-hospitalar e os fatores sociodemográficos que influenciaram esse tipo de mortalidade no período de 2015 a 2022 no Equador. Métodos. Foram analisados dados de registros de acesso público do Instituto Nacional de Estatísticas e Censos do Equador. Foram calculadas razões de mortalidade materna (RMM), com o uso de regressão logística bivariada e multivariada para obter razões de chance não ajustadas e ajustadas. Resultados. Houve um aumento nas mortes maternas relacionadas ao parto intra-hospitalar no Equador entre 2015 e 2022: as RMM aumentaram de 3,70 mortes maternas/100 mil nascidos vivos em 2015 para 32,22 em 2020 e 18,94 em 2022. A província de Manabí teve a taxa mais alta, com 84,85 mortes maternas/100 mil nascidos vivos entre 2015 e 2022. Mulheres de minorias étnicas tiveram maior probabilidade de mortalidade relacionada ao parto intra-hospitalar, com uma razão de chances ajustada (RCa) de 9,59 (intervalo de confiança de 95% [IC95%]: 6,98 a 13,18). Também foram observadas mais mortes maternas em estabelecimentos de saúde privados (RCa: 1,99, IC95%: 1,4 a 2,84). Conclusões. As inciativas para reduzir a mortalidade materna estagnaram nos últimos anos. Durante a pandemia de COVID-19 em 2020, foi observado um aumento nas mortes maternas em hospitais do Equador. Embora a pandemia possa ter contribuído para a estagnação das estimativas de mortalidade materna, fatores socioeconômicos, demográficos e clínicos desempenharam papéis fundamentais na complexidade das tendências de mortalidade materna. Os resultados deste estudo destacam a importância de abordar não apenas os aspectos clínicos da atenção, mas também os determinantes sociais da saúde e as disparidades do sistema de saúde.

Association of adverse outcomes with three-tiered risk assessment tool for obstetrical hemorrhage.

BACKGROUND: Guidelines promote stratification for the risk for postpartum hemorrhage among parturients, although the evidence for the associated differential morbidity among the groups remains inconsistent among published reports. OBJECTIVE: Using the California Maternal Quality Care Collaborative schema modified by the American College of Obstetrics and Gynecology, we compared the composite maternal hemorrhagic outcome and the composite neonatal adverse outcome among singletons who were categorized after delivery by the researchers as low-, medium-, or high-risk for postpartum hemorrhage. We hypothesized that the composite outcomes would be significantly different among the individuals in the different 3-tiered categories. STUDY DESIGN: This was a retrospective cohort study of all singleton parturients with a gestational age of at least 14 weeks who delivered at a single site within 1 year. The composite maternal hemorrhagic outcome included any of the following: estimated blood loss ≥1000 mL, use of uterotonics (excluding prophylactic oxytocin) or Bakri balloon, surgical management of postpartum hemorrhage, blood transfusion, hysterectomy, thromboembolism, admission to the intensive care unit, or maternal death. The composite neonatal adverse outcome included Apgar score <7 at 5 minutes, birth injury, bronchopulmonary dysplasia, intraventricular hemorrhage, neonatal seizure, sepsis, ventilation > 6 hrs., brachial plexus palsy, hypoxic-ischemic encephalopathy, or neonatal death. Multivariable Poisson regression models with robust error variance were used to estimate the adjusted relative risks with 95% confidence intervals. RESULTS: Of the 4544 deliveries in the study period, 4404 (96.7%) met the inclusion criteria, and among them, 1745 (39.6%) were categorized as low, 1376 (31.2%) as medium, and 1283 (29.1%) as high risk. Overall, 941 (21.4%) participants experienced the composite maternal hemorrhagic outcome with 285 (16.4%) of those being in the low-risk group, 319 (23.2%) in the medium-risk group, and 337 (26.3%) in the high-risk group. Among all parturients, 95.7% in the low-, 89.4% in the medium-, and 85.3% in the high-risk group neither had an estimated blood loss or a quantified blood loss ≥1000 mL nor were transfused. After multivariable adjustment and when compared with the low-risk group, there was a significantly higher risk for the composite maternal hemorrhagic outcome in the medium-risk group (adjusted relative risk, 1.23; 95% confidence interval, 1.05-1.43) and in the high-risk group (adjusted relative risk, 1.51; 95% confidence interval, 1.31-1.75). Overall, 366 newborns (8.4%) developed the composite neonatal adverse outcome with 76 (4.2%) in of those being in the low-risk group, 153 (11.3%) in the medium-risk group, and 140 (11.1%) in the high-risk group. After multivariable adjustment and when compared with the low-risk group, there were no significant differences in the composite neonatal adverse outcome in the medium- (adjusted relative risk, 1.27; 95% confidence interval, 0.97-1.68) or the high-risk group (adjusted relative risk, 1.29; 95% confidence interval, 0.98-1.68). CONCLUSION: Although 8 of 10 parturients categorized as high risk neither had blood loss ≥1000 mL nor underwent transfusion, the risk stratification provides information regarding the composite maternal hemorrhagic outcome.

Venous thromboembolism risk score during hospitalization in pregnancy: results of 10694 prospective evaluations in a clinical trial.

OBJECTIVES: Hospitalization during pregnancy and childbirth increases the risk of Venous Thromboembolism Risk (VTE). This study applied a VTE risk score to all hospitalized pregnant women to ascertain its effectiveness in preventing maternal death from VTE until 3 months after discharge. METHODS: In this interventional study, patients were classified as low- or high-risk according to the VTE risk score (Clinics Hospital risk score). High-risk patients (score ≥ 3) were scheduled for pharmacological Thromboprophylaxis (TPX). Interaction analysis of the main risk factors was performed using Odds Ratio (OR) and Poisson regression with robust variance. RESULTS: The data of 10694 cases (7212 patients) were analyzed; 1626 (15.2%, 1000 patients) and 9068 (84.8%, 6212 patients) cases were classified as high-risk (score ≥ 3) and low-risk (score < 3), respectively. The main risk factors (Odds Ratio, 95% Confidence Interval) for VTE were age ≥ 35 and < 40 years (1.6, 1.4-1.8), parity ≥ 3 (3.5, 3.0-4.0), age ≥ 40 years (4.8, 4.1-5.6), multiple pregnancies (2.1, 1.7-2.5), BMI ≥ 40 kg/m2 (5.1, 4.3-6.0), severe infection (4.1, 3.3-5.1), and cancer (12.3, 8.8-17.2). There were 10 cases of VTE: 7/1636 (0.4%) and 3/9068 (0.03%) in the high- and low-risk groups, respectively. No patient died of VTE. The intervention reduced the VTE risk by 87%; the number needed to treat was 3. CONCLUSIONS: This VTE risk score was effective in preventing maternal deaths from VTE, with a low indication for TPX. Maternal age, multiparity, obesity, severe infections, multiple pregnancies, and cancer were the main risk factors for VTE.

Factores de riesgo predisponentes al desarrollo de preeclampsia y eclampsia en el embarazo / Risk factors for the development of preeclampsia and eclampsia in pregnancy

Resumen La preeclampsia es una patología de origen desconocido, de alta incidencia en la salud materna y neonatal. Caracterizada como una hipertensión gestacional grave multisistémica a partir de las 20 semanas de gestación hasta el parto y posparto, siendo de los trastornos más prevalentes en el mundo y la principal causa de muerte materna en Ecuador durante 2022. El objetivo fue realizar una revisión bibliográfica respecto de los factores de riesgo que predisponen preeclampsia en embarazadas. Mediante una revisión bibliográfica de estudios correspondientes a factores predisponentes al desarrollo de preeclampsia y eclampsia en embarazadas cuyos resultados se enfocaron a pacientes adultas diagnosticadas con dichas patologías mediante estrategia PICO, aplicando criterios de inclusión y exclusión. La preeclampsia conlleva una diversidad de factores de riesgo familiares patológicos como preeclampsia previa, hipertensión o enfermedades renales, diabéticas y obesidad; otros factores incluyen: edad, raza, embarazos gemelares, multiparidad, progenitores de distinta índole. Los factores significativos para presentar la enfermedad fueron en su mayoría factores ginecoobstétricos donde destacaron multiparidad, edad, obesidad, malnutrición, hipertensión previa y factores hereditarios.

Abstract Preeclampsia is a condition of unknown origin, with a high incidence in maternal and neonatal health, characterized as a severe multisystemic gestational hypertension from the 20th week of gestation until childbirth and postpartum. Among the most prevalent disorders worldwide, in Ecuador was the main cause of maternal death during 2022. The objective was to conduct a literature review regarding risk factors that predispose pregnant women to preeclampsia. Through a literature review of studies corresponding to predisposing factors for the development of preeclampsia and eclampsia in pregnant women, whose results were focused on adult patients diagnosed with said pathologies through the PICO strategy, applying inclusion and exclusion criteria. Preeclampsia involves a variety of pathological familial risk factors such as prior preeclampsia, hypertension, renal diseases, diabetes, and obesity; other factors include age, race, twin pregnancies, multiparity, and diverse parental lineage. The significant factors for presenting the disease were mostly gynecobstetric factors, prominently multiparity, age, obesity, malnutrition, prior hypertension, and hereditary factors.

Management of unexpected placenta accreta spectrum cases in resource-poor settings.

BACKGROUND: On a global scale, cases of placenta accreta spectrum are often just identified during cesarean delivery because they are missed during antenatal care screening. Routine operating teams not trained in the management of placenta accreta spectrum are faced with difficult surgical situations and have to make decisions that may define the clinical outcomes. Although there are general recommendations for the intraoperative management of placenta accreta spectrum, no studies have described the clinical reality of unexpected placenta accreta spectrum cases in resource-poor settings. OBJECTIVE: This study aimed to describe the maternal outcomes of previously undiagnosed placenta accreta spectrum managed in resource-poor settings in Colombia and Indonesia. STUDY DESIGN: This was a retrospective case series of women with histologically confirmed placenta accreta spectrum treated in 2 placenta accreta spectrum centers after referral from remote resource-poor hospitals. Clinical outcomes were analyzed according to the initial type of management: (1) no cesarean delivery; (2) placenta left in situ after cesarean delivery; (3) partial removal of the placenta after cesarean delivery; and (4) post-cesarean hysterectomy. In addition, we evaluated the use of telemedicine by comparing the outcomes of women in hospitals that used the support of the placenta accreta spectrum center during the initial surgery. RESULTS: A total of 29 women who were initially managed in Colombia (n=2) and Indonesia (n=27) were included. The lowest volume of blood loss and the lowest frequency of complications were in women who underwent deferred cesarean delivery (n=5; 17.2%) and in those who had a delayed placental delivery (n=5; 20.7%). Five maternal deaths (14%) occurred in the group that did not receive telehelp, and 4 women died of irreversible shock because of uncontrolled bleeding. CONCLUSION: Previously undiagnosed placenta accreta spectrum in resource-poor hospitals was associated with a high risk of maternal mortality. Open-close abdominal surgery or leaving the placenta in situ seem to be the best choices for unexpected placenta accreta spectrum management in resource-poor settings. Telemedicine with a placenta accreta spectrum center may improve prognosis.

[Maternal death in Iceland 1976-2015].

INTRODUCTION: Maternal deaths are rare and an indirect measure of the societal framework surrounding pregnancy and childbirth. We surveyed and classified maternal mortality in Iceland using international guidelines, calculating changes over a 40-year period. MATERIAL AND METHODS: Information from Statistics Iceland on women aged 15-49 years who died in 1985-2015 were cross-checked against birth registration and hospital admission data to identify women who died in pregnancy or ≤42 and within 43-365 days from birth or termination of a pregnancy. Data for 1976-1984 were searched manually. Case records and autopsy reports were scrutinized. Deaths were classified as direct, indirect or coincidental and as early or late. RESULTS: Among 1600 women 48 died in pregnancy or within a year after pregnancy. Births totaled 172369 and overall maternal mortality was 27.8/100.000 births. Maternal mortality by World Health Organization criteria (direct/indirect ≤42 days) occurred in 14 instances giving a maternal mortality ratio (MMR) of 8.1/100.000. Rates lowered between the first and last 10-year periods, particularly initially followed by a lesser downward trend. Direct deaths were 6, indirect 20, coincidental 22 (accidents, diseases). Causes of direct deaths were severe preeclampsia, pulmonary embolism and choriocarcinoma. Underlying causes of indirect deaths included cancer, diabetes, brain/heart conditions and suicide. No deaths occurred from ectopic pregnancy, hemorrhage or anesthesia. CONCLUSIONS: Maternal mortality in Iceland is among the lowest reported. Women died because of the pregnancy, from worsening of underlying conditions or coincidentally. Risk groups require better support. Continued attention to adverse health connected to maternity is essential.

Perioperative complications of a transvaginal cervical cerclage in singleton pregnancies: a systematic review and meta-analysis.

OBJECTIVE: Given that many studies report on a limited spectrum of adverse events of transvaginal cervical cerclage for preventing preterm birth, but are not powered to draw conclusions about its safety, the objective of this study was to conduct a systematic review with pooled risk analyses of perioperative complications and compare characteristics on the basis of indication for cerclage in singleton pregnancies. DATA SOURCES: Ovid MEDLINE, Ovid Embase, Web of Science, the Cochrane Central Register of Controlled Trials (CENTRAL), and the prospective trial registers ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched from inception to April 2020. STUDY ELIGIBILITY CRITERIA: All randomized controlled trials and both retrospective and prospective observational cohort studies reporting about complications in history-indicated cerclage, ultrasound-indicated cerclage, or physical examination-indicated cerclage were eligible. Studies were included if they contained original data on the occurrence of adverse events during surgery or within 24 hours after surgery. METHODS: The Cochrane risk of bias tool for randomized controlled trials and the Newcastle-Ottawa scale for cohort and case-control studies were used for the critical appraisal. The pooled risk assessment was conducted using meta and metafor packages in R (studio), version 4.0.3. RESULTS: The search yielded 2328 potential studies; 3 randomized controlled trials, 3 prospective, and 38 retrospective cohort studies were included in the final analysis. Of the 4511 women with singleton gestations, 1561 (34.6%) underwent history-indicated cerclage, 1348 (29.9%) underwent ultrasound-indicated cerclage, and 1549 (33.3%) underwent physical examination-indicated cerclage. Most perioperative complications occurred in physical examination-indicated cerclage, especially hemorrhage (2.3%; 95% confidence interval, 0.0-7.6) and preterm premature rupture of membranes (2.5%; 95% confidence interval, 0.91-4.5). The fewest complications occurred in history-indicated cerclage, varying from 0.0% of preterm premature rupture of membranes (95% confidence interval, 0.0-1.7) to 0.9% of hemorrhage (95% confidence interval, 0.0-7.9). In ultrasound-indicated cerclage, the most common complication was hemorrhage (1.4%; 95% confidence interval, 0.0-4.1), followed by lacerations (0.6%; 95% confidence interval, 0.0-3.1) and preterm premature rupture of membranes (0.3%; 95% confidence interval, 0.0-0.8). CONCLUSION: The highest risk of perioperative complications was observed in physical examination-indicated cerclage in comparison with ultrasound- and history-indicated cerclage. However, the occurrence of complications is poorly documented in the published literature, as is the timing of the complications (ie, perioperative or later in pregnancy). There is an urgent need for uniform complication reporting policy in both cohort studies and randomized controlled trials on cerclage.

Maternal and fetal/neonatal outcomes of pregnancies complicated by pulmonary hypertension: a retrospective study of 154 patients

Abstract Objectives: To determine the main clinical and demographic outcomes related to Pulmonary Hypertension (PH) and adverse obstetric and fetal/neonatal outcomes. Methods: This study retrospectively analyzed the medical record data of 154 patients with PH who were admitted to the Third Affiliated Hospital of Guangzhou Medical University between January 2011 and December 2020. Results: According to the severity of elevated Pulmonary Artery Systolic Pressure (PASP), 82 women (53.2%) were included in the mild PH group, 34 (22.1%) were included in the moderate PH group, and 38 (24.7%) were included in the severe PH group. There were significant differences in the incidence of heart failure, premature delivery, Very-Low-Birth-Weight (VLBW) infants, and Small-for-Gestational-Age (SGA) infants among the three PH groups (p < 0.05). Five (3.2%) women died within 7-days after delivery, 7 (4.5%) fetuses died in utero, and 3 (1.9%) neonates died. The authors found that PASP was an independent risk factor for maternal mortality. After adjustment for age, gestational weeks, systolic blood pressure, Body Mass Index (BMI), mode of delivery, and anesthesia, the risk of maternal mortality in the severe PH group was 20.21 times higher than that in the mildmoderate PH group (OR = 21.21 [95% CI 1.7~264.17]), p < 0.05. All 131 (85.1%) patients were followed up for 12 months postpartum. Conclusions: The authors found that the risk of maternal mortality in the severe PH group was significantly higher than that in the mild-moderate group, highlighting the importance of pulmonary artery pressure screening before pregnancy, early advice on contraception, and multidisciplinary care.

Factors associated with the evolution of COVID-19 in pregnant women: a Brazilian population-based study / Factores asociados a la evolución de la COVID-19 en mujeres embarazadas: un estudio poblacional brasileño / Fatores associados à evolução da COVID-19 em gestantes: estudobrasileiro de base populacional

ABSTRACT Objective: To assess the evolution of COVID-19 among Brazilian pregnant women, identifying sociodemographic and clinical predictors related to admission to ICU - Intensive Care Unit and death. Method: Cross-sectional, population-based study, carried out with a secondary database, based on data from the Influenza Epidemiological Surveillance Information System. Descriptive analysis was performed, followed by multiple linear regression with Poisson response, adopting critical p < 0.05. Results: Intensive care admission rates of 28.2% and death rates of 9.5% were identified. Region of residence, gestational trimester, number of comorbidities and respiratory signs and symptoms were associated with the risk of admission to intensive care. Age over 34 years, comorbidities, oxygen saturation equal to or less than 95%, admission to intensive care and ventilatory support, invasive or not, increased the risk of death. Conclusion: Sociodemographic and clinical predictors showed an association with hospitalization in intensive care and death of pregnant women with COVID-19.

RESUMEN Objetivo: Evaluar la evolución de la COVID-19 entre gestantes brasileñas, identificando predictores sociodemográficos y clínicos relacionados con el ingreso en unidad de cuidados intensivos y la muerte. Método: Estudio transversal, de base poblacional, realizado con una base de datos secundaria, a partir de datos del Sistema de Información de Vigilancia Epidemiológica de Influenza. Se realizó un análisis descriptivo, seguido de regresión lineal múltiple con respuesta de Poisson, adoptando una p crítica <0,05. Resultados: Se identificaron tasas de ingreso a cuidados intensivos del 28,2% y tasas de mortalidad del 9,5%. La región de residencia, el trimestre gestacional, el número de comorbilidades y los signos y síntomas respiratorios se asociaron con el riesgo de ingreso a cuidados intensivos. La edad mayor de 34 años, las comorbilidades, la saturación de oxígeno igual o inferior al 95%, el ingreso a cuidados intensivos y el soporte ventilatorio, sea invasivo o no, aumentaron el riesgo de muerte. Conclusión: Los predictores sociodemográficos y clínicos mostraron asociación con la hospitalización en cuidados intensivos y la muerte en gestantes con COVID-19.

Morbimortalidade materna no Brasil e a urgência de um sistema nacional de vigilância do near miss materno / Maternal morbidity and mortality in Brazil and the urgency of a national surveillance system for maternal near miss / La morbimortalidad materna en Brasil y la urgencia de un sistema nacional de vigilancia del near miss materno

A Organização Mundial da Saúde (OMS) recomenda a análise dos casos de morbidade materna severa/near miss materno como complemento às análises das mortes de mães, dado que a incidência é mais elevada e os fatores preditivos dos dois desfechos são semelhantes. Tendo em vista que as razões de mortalidade materna, no Brasil, têm se mantido constantes apesar do compromisso firmado durante a Assembleia Geral da Organização das Nações Unidas (ONU), em 2015, o objetivo deste artigo é propor um sistema nacional de vigilância de near miss materno. Propõe-se a inclusão dos eventos near miss materno na Lista Nacional de Notificação Compulsória de Doenças, Agravos e Eventos de Saúde Pública, por meio da compatibilização dos critérios diagnósticos de near miss materno, informados pela OMS, com os códigos da Classificação Internacional de Doenças (CID) para identificação dos casos. Tendo em vista que a vigilância em saúde se faz baseada em diversas fontes de informações, a notificação poderia ser feita pelos profissionais dos serviços de saúde tão logo fosse identificado um caso confirmado ou suspeito. A partir do estudo dos fatores associados aos desfechos, espera-se a avaliação mais qualificada dos serviços voltados à assistência obstétrica e consequente implementação de políticas mais eficientes de prevenção não apenas do óbito materno, mas de eventos que podem tanto causar sequelas irreversíveis à saúde da mulher quanto aumento do risco de óbito fetal e neonatal.

The World Health Organization (WHO) recommends the analysis of severe maternal morbidity/maternal near miss cases as complementary to the analysis of maternal deaths since the incidence is higher and the predictive factors of the two outcomes are similar. Considering that the reasons for maternal mortality in Brazil have remained constant despite the commitment made during the General Assembly of the United Nations in 2015, this article aims to propose a nationwide maternal near miss surveillance system. We propose the inclusion of maternal near miss events in the National List of Compulsory Notification of Diseases, Injuries, and Public Health Events, via the compatibility of the diagnostic criteria of maternal near miss, informed by the WHO, with the codes of the International Classification of Diseases for the identification of cases. Considering that health surveillance is based on several sources of information, notification could be made by health service professionals as soon as a confirmed or suspected case is identified. With the study of the factors associated with the outcomes, we expect a qualified evaluation of the services focused on obstetric care and consequent implementation of more efficient policies to prevent not only maternal death but also events that can both cause irreversible sequelae to women's health and increase the risk of fetal and neonatal death.

La Organización Mundial de la Salud (OMS) recomienda el análisis de los casos de morbilidad materna grave/near miss materno como complemento a los análisis de las muertes maternas, dado que la incidencia es más elevada y los factores predictivos de los dos resultados son similares. Teniendo en vista que las razones de mortalidad materna, en Brasil, se han mantenido constantes a pesar del compromiso firmado durante la Asamblea General de la Organización de las Naciones Unidas, en el año 2015, el objetivo de este artículo es proponer un sistema de vigilancia de near miss materno de alcance nacional. Se propone la inclusión de los eventos de near miss materno en la Lista Nacional de Notificación Obligatoria de Enfermedades, Agravios y Eventos de Salud Pública, por medio de la compatibilización de los criterios diagnósticos de near miss materno; informados por la OMS, con los códigos de la Clasificación Internacional de Enfermedades para identificación de los casos. Teniendo en vista que la vigilancia en salud se basa en diversas fuentes de Informaciones, la notificación podría ser hecha por los profesionales de los servicios de salud, tan pronto fuese identificado un caso confirmado o sospechoso. Se espera que el estudio de los factores asociados a los resultados conduzca a una evaluación más calificada de los servicios de atención obstétrica y a la consecuente implementación de políticas más eficientes de prevención no solo de la muerte materna; sino de eventos que pueden tanto causar secuelas irreversibles a la salud de la mujer como aumento del riesgo de muerte fetal y neonatal.

Venous thromboembolism risk score during hospitalization in pregnancy: results of 10694 prospective evaluations in a clinical trial

Abstract Objectives Hospitalization during pregnancy and childbirth increases the risk of Venous Thromboembolism Risk (VTE). This study applied a VTE risk score to all hospitalized pregnant women to ascertain its effectiveness in preventing maternal death from VTE until 3 months after discharge. Methods In this interventional study, patients were classified as low- or high-risk according to the VTE risk score (Clinics Hospital risk score). High-risk patients (score ≥ 3) were scheduled for pharmacological Thromboprophylaxis (TPX). Interaction analysis of the main risk factors was performed using Odds Ratio (OR) and Poisson regression with robust variance. Results The data of 10694 cases (7212 patients) were analyzed; 1626 (15.2%, 1000 patients) and 9068 (84.8%, 6212 patients) cases were classified as high-risk (score ≥ 3) and low-risk (score < 3), respectively. The main risk factors (Odds Ratio, 95% Confidence Interval) for VTE were age ≥ 35 and < 40 years (1.6, 1.4-1.8), parity ≥ 3 (3.5, 3.0-4.0), age ≥ 40 years (4.8, 4.1-5.6), multiple pregnancies (2.1, 1.7-2.5), BMI ≥ 40 kg/m2 (5.1, 4.3-6.0), severe infection (4.1, 3.3-5.1), and cancer (12.3, 8.8-17.2). There were 10 cases of VTE: 7/1636 (0.4%) and 3/9068 (0.03%) in the high- and low-risk groups, respectively. No patient died of VTE. The intervention reduced the VTE risk by 87%; the number needed to treat was 3. Conclusions This VTE risk score was effective in preventing maternal deaths from VTE, with a low indication for TPX. Maternal age, multiparity, obesity, severe infections, multiple pregnancies, and cancer were the main risk factors for VTE.

Haemophagocytic lymphohistiocytosis in pregnancy.

Haemophagocytic lymphohistiocytosis is a life-threatening systemic inflammatory syndrome defined by persistent fever, cytopenia and multi-organ dysfunction. Primary haemophagocytic lymphohistiocytosis classically presents in childhood as a result of genetically abnormal perforin or inflammasome function, leading to the aberrant release of pro-inflammatory cytokines causing a hyperinflammatory state. Secondary haemophagocytic lymphohistiocytosis is an acquired phenomenon occurring at any age as a result of immune dysregulation to a specific trigger such as infection, haematological malignancy or autoimmune disease. Secondary haemophagocytic lymphohistiocytosis occurring in the pregnant woman represents a diagnostic challenge and carries a significant mortality. This has led to its first inclusion in the fourth Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries across the United Kingdom annual maternal report in 2017. This article presents an overview of haemophagocytic lymphohistiocytosis, reviews the literature on haemophagocytic lymphohistiocytosis in pregnancy, suggests diagnostic pathways and explores the safety and efficacy of existing and potential treatment strategies for haemophagocytic lymphohistiocytosis occurring during pregnancy.

Comparing pregnancy outcomes between symptomatic and asymptomatic COVID-19 positive unvaccinated women: Multicenter study in Saudi Arabia.

INTRODUCTION: COVID-19 infection in pregnancy ranges from asymptomatic infection to severe disease. However, the maternal and pregnancy outcomes are primarily favorable. Acute Respiratory Illness (ARI) score is a Visual Triage Checklist for Acute Respiratory symptoms created by the ministry of health of Saudi Arabia 12 to screen the patient for acute respiratory infection with MERS-CoV. It has been used during the COVID-19 pandemic to identify suspected cases and place patients in isolation precautions if the score is≥ 4. METHOD: This study is a cross-sectional study of all pregnant women who tested positive for COVID-19 in four medical centers located in four different cities in Saudi Arabia. The study period was from 1/3/2020 until 31/10/2020. Outcomes investigated were the prevalence of COVID infection in pregnant women at the time of delivery. Rate of asymptomatic disease, different maternal and pregnancy outcomes. Women were divided into symptomatic and asymptomatic groups according to the ARI score. The two groups were compared in maternal, perinatal, and neonatal outcomes. Furthermore, the cohort was divided according to maternal age into two groups: women of advanced maternal age ≥ 35 years and younger. The two groups were compared in maternal, perinatal, and neonatal outcomes RESULTS: During the study period, 9573 women gave birth at KAMCs, and 402 pregnant women were identified as COVID positive. Out of all COVID-positive women, only 394 women gave birth at KAMCs. The screening for COVID infection differed between the centers, but the testing was the same by the Nasopharyngeal polymerase chain reaction (PCR) swab. In Riyadh, screening was based on ARI scoring at the beginning of the pandemic. Then, it became universal. In Jeddah, the screening was based on ARI scoring. Any woman who scored four or more was labeled as suspected, and she was tested. Finally, in Madinah and Dammam, the screening was universal throughout the study. The prevalence of COVID-19 infection among women who gave birth at KAMCs was 4.2% (402/9573). (CI 3.8-4.6%). At the time of diagnosis, most women (62%) were asymptomatic. The most common symptoms were cough and shortness of breath. Twenty-two women (5.5%) had Pneumonia, and five women (1.3%) needed admission to Intensive care units (ICU). One woman died due to respiratory failure. When pregnancy outcomes were compared between symptomatic and asymptomatic women, pregnancy in symptomatic women was more likely to be complicated by Abortion (6 versus 2% p-value 0.00), fetal death (3 versus 1.3%), and cesarean delivery (30.8 versus 22.4%, p-value 0.001). COVID-positive pregnant women of advanced maternal age (AMA) were more likely to be symptomatic, have Abortion (5 versus 1%, p-value 0.01), and have Preterm delivery (17 versus 11% p-value 0.01) than younger women. In addition, neonatal death was more common in AMA COVID-positive women than younger (4 versus 0%), regardless of COVID-related symptoms. CONCLUSION: Most of the COVID-infected pregnant women are asymptomatic. Therefore, the ARI scoring system does not help to triage patients. Symptomatic women, especially those older than 35, tend to have a higher maternal and pregnancy complication rate.

Pregnancy Outcomes in Women With Mechanical Valve Prostheses Using Vitamin K Antagonist Therapy: The Experience of the Salam Centre for Cardiac Surgery in Sudan.

Pregnancy and childbirth on anticoagulants after mechanical heart valve replacement present a high risk of complications for both mother and baby. On top of pregnancy worsening the mother's cardiac function, anticoagulant therapy itself is a crucial problem. A safe and effective anticoagulation regimen for both mother and fetus is not possible. The most effective drugs for preventing valve thrombosis are VKAs, whose dosage needs to be adjusted with frequent INR checks. Moreover, VKAs can have embryopathic and teratogenic action. Patients in follow-up and anticoagulant treatment at the Salam Centre for Cardiac Surgery in Sudan live spread out over a large area where transport to the Center is generally difficult; pregnancy treatment has, therefore, been adapted to the limitations of reality. Pregnancy is discouraged and contraception and therapeutic abortion are recommended, but this guidance frequently goes unheeded. Here we describe maternal and fetal outcomes in 307 consecutive pregnancies recorded by staff at the oral anticoagulant clinic (OAC) from April 2017 to November 2021. Out of 307 pregnancies, there were 15 maternal deaths (4.9%), 24 thrombotic events (7.8%) and 22 major bleedings (7.2%). Fifty pregnancies (16.3%) were terminated by therapeutic abortion. Only 47.6% of pregnancies had good maternal and neonatal outcomes. Data clearly show that, due to the complexity of pregnancy in women with mechanical heart valves and the scarcity of tertiary healthcare services in the area where patients live, maternal mortality is at an unacceptable level and requires a structured, multi-disciplinary intervention.

Maternal Deaths from COVID-19 in Brazil: Increase during the Second Wave of the Pandemic / Mortes maternas por COVID-19 no Brasil: Aumento durante a segunda onda da pandemia

Abstract Objective To compare death rates by COVID-19 between pregnant or postpartum and nonpregnant women during the first and second waves of the Brazilian pandemic. Methods In the present population-based evaluation data from the Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe, in the Portuguese acronym), we included women with c (ARDS) by COVID-19: 47,768 in 2020 (4,853 obstetric versus 42,915 nonobstetric) and 66,689 in 2021 (5,208 obstetric versus 61,481 nonobstetric) and estimated the frequency of in-hospital death. Results We identified 377 maternal deaths in 2020 (first wave) and 804 in 2021 (second wave). The death rate increased 2.0-fold for the obstetric (7.7 to 15.4%) and 1.6-fold for the nonobstetric groups (13.9 to 22.9%) from 2020 to 2021 (odds ratio [OR]: 0.52; 95% confidence interval [CI]: 0.47-0.58 in 2020 and OR: 0.61; 95%CI: 0.56- 0.66 in 2021; p < 0.05). In women with comorbidities, the death rate increased 1.7-fold (13.3 to 23.3%) and 1.4-fold (22.8 to 31.4%) in the obstetric and nonobstetric groups, respectively (OR: 0.52; 95%CI: 0.44-0.61 in 2020 to OR: 0.66; 95%CI: 0.59-0.73 in 2021; p <0.05). In women without comorbidities, the mortality rate was higher for nonobstetric (2.4 times; 6.6 to 15.7%) than for obstetric women (1.8 times; 5.5 to 10.1%; OR: 0.81; 95%CI: 0.69-0.95 in 2020 and OR: 0.60; 95%CI: 0.58-0.68 in 2021; p <0.05). Conclusion There was an increase in maternal deaths from COVID-19 in 2021 compared with 2020, especially in patients with comorbidities. Death rates were even higher in nonpregnant women, with or without comorbidities.

Resumo Objetivo Comparar as taxas de mortalidade por COVID-19 entre gestantes ou puérperas e não gestantes durante a primeira e segunda ondas da pandemia brasileira. Métodos Na presente avaliação dos dados do Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe), incluímos mulheres com síndrome respiratória aguda grave por COVID-19: 47.768 em 2020 (4.853 obstétricas versus 42.915 não obstétricas) e 66.689 em 2021 (5.208 obstétricas versus 61.481 não obstétricas) e estimamos a frequência de óbito intra-hospitalar. Resultados Identificamos 377 óbitos maternos em 2020 e 804 em 2021. A taxa de mortalidade por COVID-19 aumentou 2,0 vezes no grupo obstétrico (de 7,7 para 15,4%) e 1,6 vezes no grupo não obstétrico (de 13,9 para 22,9%) de 2020 a 2021 (odds ratio [OR]: 0,52; intervalo de confiança [IC] 95%: 0,47-0,58 em 2020 e OR: 0,61; IC95%: 0,56-0,66 em 2021; p <0,05). Em mulheres com comorbidades, a taxa de óbitos aumentou 1,7 vezes (de 13,3 para 23,3%) e 1,4 vezes (de 22,8 para 31,4%) para os grupos obstétricos e não obstétricos, respectivamente (OR: 0,52; IC95%: 0,44-0,61 em 2020 para OR: 0,66; IC95%: 0,59-0,73 em 2021; p <0,05). Em mulheres sem comorbidades, a taxa de mortalidade foi maior para as não obstétricas (2,4 vezes; de 6,6% para 15,7%) do que para mulheres obstétricas (1,8 vezes; de 5,5 para 10,1%; OR: 0,81; IC95%: 0,69-0,95 em 2020 e OR: 0,60; IC95%: 0,58-0,68 em 2021; p < 0,05). Conclusão Houve aumento das mortes maternas por COVID-19 em 2021 em relação a 2020, principalmente naquelas com comorbidades. As taxas de mortalidade foram ainda maiores em mulheres não grávidas, com ou sem comorbidades.

Maternal mortality and its determining factors among hospitalised mothers in Tehran, Iran, 2013-2020.

The maternal mortality ratio (MMR) is a significant indicator of the quality of a health care system. Despite considerable progress in reducing MMR in Iran in the past few years, we still face a long road ahead in eliminating preventable maternal deaths. In the present study, we evaluated all 80 cases of maternal deaths in 20 hospitals under the supervision of Tehran University of Medical Sciences between March 20 2013 and March 19 2020. During this time, these hospitals recorded 335,216 live births, with an MMR of 24 per 100,000 live births. The average age of deceased mothers was 31.9 ± 6.9 years. Direct causes accounted for 48.75% of maternal deaths, with haemorrhage being the most common direct cause of mortality (17.5%). Moreover, cancer (17.5%) and cardiovascular diseases (17.5%) were the most common indirect causes of maternal mortality. Even after accounting for the COVID-19 pandemic's effects, we have noticed an increase in maternal mortality. As a result, implementing a comprehensive approach for high-risk pregnancies is critical.Impact StatementWhat is already known on this subject? Although we have been able to reduce MMR in Iran to a reasonable level, previous measures would not be sufficient to accomplish future goals. Furthermore, we have a long way to go before reaching the ultimate goal of eradicating avoidable maternal deaths by 2030.What do the results of this study add? The causes, determinants and risk factors of maternal mortality were investigated in this study. With this level of detail, we can observe a steadily increase in MMR in recent years, regardless of the COVID-19 pandemic. The majority of pregnancy-related deaths can be avoided.What are the implications of these findings for clinical practice and/or further research? MMR reduction is a measurable goal that can be attained by improving financial resources, implementing safe delivery, team training, preparing multidisciplinary care with integration for high-risk pregnant women, establishing good provider relationships, and communicating with patients and providers for early warning signs and structural changes.
