Abstract Objective: To ascertain how screening for preterm birth is performed among obstetricians working in public and private practice in a middle-income country. Methods: Cross-sectional study of 265 obstetrician-gynecologists employed at public and private facilities. An online questionnaire was administered, with items designed to collect data on prematurity screening and prevention practices. Results: The mean age of respondents was 44.5 years; 78.5% were female, and 97.7% had completed a medical residency program. Universal screening (i.e., by ultrasound measurement of cervical length) was carried out by only 11.3% of respondents in public practice; 43% request transvaginal ultrasound if the manual exam is abnormal, and 74.6% request it in pregnant women with risk factors for preterm birth. Conversely, 60.7% of respondents in private practice performed universal screening. This difference in screening practices between public and private practice was highly significant (p < 0.001). Nearly all respondents (90.6%) reported prescribing vaginal progesterone for short cervix. Conclusion: In the setting of this study, universal ultrasound screening to prevent preterm birth was used by just over half of doctors in private practice. In public facilities, screening was even less common. Use of vaginal progesterone in cervical shortening was highly prevalent. There is an unmet need for formal protocols for screening and prevention of preterm birth in middle-income settings.

Abstract Objective Compare the number of puerperal women submitted to blood transfusion before and after the implementation of a care protocol for postpartum hemorrhage (PPH) with multidisciplinary team training. Methods Cross-sectional study in a university hospital, analyzing births from 2015 to 2019, compared the use of blood products before and after the adoption of a PPH protocol with multidisciplinary training. Results Between 2015 and 2019, there were 17,731 births, with 299 (1.7%) postpartum women receiving blood products and 278 postpartum women were considered for this analysis, 128 (0.7%) at Time 1 and 150 (0.8%) at Time 2. After the multiprofessional team training (T2), there was a difference in the complete use of the PPH protocol (use of oxytocin, misoprostol and tranexamic acid) (T1 = 5.1% x T2 = 49.5%, p≤0.0001). An individual categorized analysis revealed that, in the T2 period, there was lower use of blood component units per patient compared to T1 (Mann-Whitney, p=0.006). It should be noted that at T1 and T2, 54% and 24% respectively received two units of blood products. It is important to highlight that after the multidisciplinary team training for the PPH protocol, the goal of zero maternal death due to hemorrhage was reached. Conclusion The adoption of a specific protocol for PPH, combined with the training of a multidisciplinary team, had an impact on the ability to identify women at high risk of hemorrhage, resulting in a decrease in the use of blood components.

Resumo Objetivo Avaliar o impacto da raça (negra versus não negra) nos desfechos maternos e perinatais de gestantes com COVID-19 no Brasil. Métodos Esta é uma subanálise da REBRACO, um estudo de coorte multicêntrico brasileiro desenhado para avaliar o impacto da COVID-19 em mulheres grávidas. De fevereiro de 2020 a fevereiro de 2021, 15 maternidades do Brasil coletaram dados de mulheres com sintomas respiratórios. Selecionamos todas as mulheres com teste positivo para COVID-19; em seguida, as dividimos em dois grupos: mulheres negras e não negras. Finalmente, comparamos, entre os grupos, os resultados sociodemográficos, maternos e perinatais. Obtivemos a frequência dos eventos em cada grupo e comparamos usando o teste X2; Valores de p <0,05 foram considerados significativos. Também estimamos o odds ratio (OR) e os intervalos de confiança (IC). Resultados 729 mulheres sintomáticas foram incluídas no estudo; desses, 285 foram positivos para COVID-19, 120 (42,1%) eram negros e 165 (57,9%) não eram negros. As mulheres negras apresentaram pior escolaridade (p = 0,037). O tempo de acesso ao sistema de saúde foi semelhante entre os dois grupos, com 26,3% incluídos com sete ou mais dias de sintomas. Síndrome respiratória aguda grave (OR 2,22 CI 1,17–4,21), admissão em unidade de terapia intensiva (OR 2,00 CI 1,07–3,74) e dessaturação na admissão (OR 3,72 CI 1,41–9,84) foram mais prováveis de ocorrer entre mulheres negras. A mortalidade materna foi maior entre as negras (7,8% vs. 2,6%, p = 0,048). Os resultados perinatais foram semelhantes entre os dois grupos.

Abstract Objective To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI). Results 729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17–4.21), intensive care unit admission (OR 2.00 CI 1.07–3.74), and desaturation at admission (OR 3.72 CI 1.41–9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups.

Resumo Objetivo Determinar o perfil dos óbitos maternos ocorridos no período de 2000 a 2019 no Hospital de Clínicas de Porto Alegre (HCPA) e comparar com os óbitos maternos entre 1980 e 1999 na mesma instituição. Métodos Estudo retrospectivo que analisou 2.400 prontuários de mulheres entre 10 e 49 anos que morreram entre 2000 e 2019. O presente estudo foi aprovado pelo Comitê de Ética (CAAE 78021417600005327). Resultados Após revisão de 2.481 prontuários de mulheres que morreram em idade reprodutiva, 43 mortes ocorreram durante a gravidez ou no período pós-parto. Destas, 28 foram considerados óbitos maternos. A taxa de mortalidade materna foi de 37.6 por 100.000 nascidos vivos. Em relação às causas, 16 óbitos (57.1%) estiveram diretamente associados à gravidez, 10 (35.1%) estiveram indiretamente associados e 2 (7.1%) não estiveram relacionados. A principal causa de morte foi hipertensão na gravidez (31.2%) seguida de esteatose hepática aguda da gravidez (25%). No estudo anterior, publicado em 2003 na mesma instituição4, a taxa de mortalidade foi de 129 por 100.000 nascidos vivos, e a maioria dos óbitos estava relacionada a causas obstétricas diretas (62%). As principais causas de óbito neste período foram por complicações hipertensivas (17.2%), seguidas de infecção pós-cesárea (16%). Conclusão Em comparação com os dados anteriores à década de 2000, houve uma redução importante das mortes maternas por causas infecciosas.

Abstract Objective To determine the profile of maternal deaths occurred in the period between 2000 and 2019 in the Hospital de Clínicas de Porto Alegre (HCPA, in the Portuguese acronym) and to compare it with maternal deaths between 1980 and 1999 in the same institution. Methods Retrospective study that analyzed 2,481 medical records of women between 10 and 49 years old who died between 2000 and 2018. The present study was approved by the Ethics Committee (CAAE 78021417600005327). Results After reviewing 2,481 medical records of women who died in reproductive age, 43 deaths had occurred during pregnancy or in the postpartum period. Of these, 28 were considered maternal deaths. The maternal mortality ratio was 37.6 per 100,000 live births. Regarding causes, 16 deaths (57.1%) were directly associated with pregnancy, 10 (35.1%) were indirectly associated, and 2 (7.1%) were unrelated. The main cause of death was hypertension during pregnancy (31.2%) followed by acute liver steatosis during pregnancy (25%). In the previous study, published in 2003 in the same institution4, the mortality rate was 129 per 100,000 live births, and most deaths were related to direct obstetric causes (62%). The main causes of death in this period were due to hypertensive complications (17.2%), followed by postcesarean infection (16%). Conclusion Compared with data before the decade of 2000, there was an important reduction in maternal deaths due to infectious causes.

Resumo Vasa previa (VP) é uma condição obstétrica perigosa associada a mortalidade e morbidade perinatais. Fertilização in vitro (FIV) é um fator de risco para VP devido à alta incidência de placentação anormal. O diagnóstico deve ser realizado no período pré-natal, pois a possibilidade de mortalidade fetal é extremamente elevada. Relatamos dois casos para demonstrar a acurácia da ultrassonografia transvaginal no diagnóstico pré-natal de VP. Mulher caucasiana, primigesta, de 40 anos, submetida a FIV, foi diagnosticada com VP na 29ª semana de gestação e hospitalizada para observação na 31ª semana de gestação. A paciente foi submetida à cesariana eletiva com 34 semanas e 4 dias, sem complicações, com recém-nascido do sexo masculino, pesando 2.380 g, e com Apgar de 10 no 5° minuto. Mulher caucasiana, primigesta, de 36 anos, subetida a FIV, foi diagnosticada com placenta prévia, placenta bilobada, acretismo placentário e VP. Cordão umbilical com inserção velamentosa. A paciente foi hospitalizada para observação na 26ª semana de gestação. Foi submetida à cesariana de emergência com33 semanas e 4 dias por sangramento vaginal. O recém nascido do sexo feminino pesou 2.140 g, com Apgar de 9 no 5°minuto. O diagnóstico de VP no período pré-natal associou-se a um desfecho favorável nos dois casos, corroborando observações anteriores de que a FIV é um fator de risco para VP e de que todas as gestações por FIV deveriam ser avaliadas por ultrassonografia transvaginal.

Abstract Vasa previa (VP) is a dangerous obstetric condition associated with perinatal mortality and morbidity. In vitro fertilization (IVF) is a risk factor for VP due to the high incidence of abnormal placentation. The diagnosis should be made prenatally, because fetal mortality can be extremely high. We report two cases to demonstrate the accuracy of transvaginal ultrasound in the prenatal diagnosis of VP. A 40-year-old primiparous Caucasian woman with IVF pregnancy was diagnosed with VP at 29 weeks of gestation and was hospitalized for observation at 31 weeks of gestation. She delivered a male newborn weighing 2,380 g, with an Apgar score of 10 at 5 minutes, by elective cesarean section at 34 weeks + 4 days of gestation, without complications. A 36-yearold primiparous Caucasian woman with IVF pregnancy was diagnosed with placenta previa, bilobed placenta increta and VP. The cord insertion was velamentous. She was hospitalized for observation at 26 weeks of gestation. She delivered a female newborn weighing 2,140 g, with an Apgar score of 9 at 5 minutes, by emergency cesarean section at 33 weeks + 4 days of gestation due to vaginal bleeding. The prenatal diagnosis of VP was associated with a favorable outcome in the two cases, supporting previous observations that IVF is a risk factor for VP and that all IVF pregnancies should be screened by transvaginal ultrasound.

The prediction or early diagnosis of maternal complications is challenging mostly because the main conditions, such as preeclampsia, preterm birth, fetal growth restriction, and gestational diabetes mellitus, are complex syndromes with multiple underlying mechanisms related to their occurrence. Limited advances in maternal and perinatal health in recent decades with respect to preventing these disorders have led to new approaches, and “omics” sciences have emerged as a potential field to be explored. Metabolomics is the study of a set of metabolites in a given sample and can represent the metabolic functioning of a cell, tissue or organism. Metabolomics has some advantages over genomics, transcriptomics, and proteomics, as metabolites are the final result of the interactions of genes, RNAs and proteins. Considering the recent “boom” in metabolomic studies and their importance in the research agenda, we here review the topic, explaining the rationale and theory of the metabolomic approach in different areas of maternal and perinatal health research for clinical practitioners. We also demonstrate the main exploratory studies of these maternal complications, commenting on their promising findings. The potential translational application of metabolomic studies, especially for the identification of predictive biomarkers, is supported by the current findings, although they require external validation in larger datasets and with alternative methodologies.

RESUMO RESUMO: No Brasil, o aborto induzido é permitido por lei em casos de estupro, risco de morte para a gestante e anencefalia fetal. Entretanto, a literatura relata que alguns médicos recusam atender mulheres com tais demandas, ou o fazem de maneira discriminatória. OBJETIVO: Pré-testar, testar e avaliar as propriedades da medida do “Mosaico de opiniões sobre o aborto induzido”, um questionário para investigar as perspectivas de profissionais da saúde brasileiros sobre a moralidade do aborto. MÉTODOS: Primeiro, o questionário foi pré-testado em uma amostra intencional de especialistas. Em segundo lugar, foi testado em uma amostra aleatória de 32 profissionais da saúde. Finalmente, conduziu-se um estudo multicêntrico em sete hospitais universitários para avaliar as propriedades da medida do questionário. RESULTADOS: Combinadas, as amostras das três fases totalizaram 430 sujeitos. No pré-teste e no teste, todos os aspectos avaliados obtiveram resultados satisfatórios. Na fase multicêntrica, a análise fatorial confirmatória levou a uma importante redução do questionário, que também obteve bons indicadores de confiabilidade, além da validade de construto e de critério. CONCLUSÕES: O questionário foi validado e encontra-se apto para ser utilizado em outras pesquisas no Brasil.

SUMMARY In Brasil, abortion is legal in cases of rape, when there is a risk of maternal death, and in cases of fetal anencephaly. However, the literature reports that some doctors refuse to care for women with such demands or come to perform it in a discriminatory manner. OBJECTIVE: Pretest, test and evaluate the measurement properties of the “Mosaic of Opinions on Induced Abortion,” a questionnaire developed to investigate the perspectives of Brazilian healthcare professionals about the morality of abortion. METHODS: Firstly, the questionnaire was pretested in an intentional sample of specialists. Secondly, it was tested in a randomized sample of 32 healthcare professionals. Finally, we conducted a multi-center study in seven university hospitals to evaluate the measurement properties of the questionnaire. RESULTS: Combined samples of the three phases totalized 430 individuals. In pretest and test, all the evaluated aspects obtained satisfactory results. In the multicenter phase, confirmatory factorial analysis led to an important reduction of the questionnaire, which also obtained good indicators of reliability, beyond the validation of construct and criteria. CONCLUSION: Questionnaire has been validated and is suitable for use in other surveys in Brasil.

CONTEXTO E OBJETIVO Alterações na excreção de sódio têm sido estudadas na pré-eclâmpsia relacionadas a vários fatores. O objetivo deste estudo foi comparar natriúria (mEq/24 h) com os níveis de calciúria (mg/24 h) em pacientes pré-eclâmpticas. ESTUDO E LOCAL Estudo transversal analítico com grupo controle foi realizado no Centro Obstétrico e no Ambulatório de Gestação de Alto Risco em um hospital universitário no sul do Brasil, e na Unidade Básica de Saúde na mesma cidade, incluindo gestantes com pré-eclâmpsia leve e grave, hipertensão crônica e gestações normais, com 14 pacientes em cada grupo. MÉTODO A natriuria foi dosada através da medida de íon eletrodo seletivo, utilizando analizadores automáticos de química clínica (Hitache 917 Roche). Todas as pacientes coletaram urina de 24 h, em casa ou no hospital, para análise de proteínas, creatinina, cálcio, ácido úrico e sódio. As variáveis quantitativas com distribuição assimétrica foram descritas por mediana, mínimo e máximo, e comparadas por teste Kruskal-Wallis. Os resultados foram transformados logaritmicamente, com ANOVA one-way por ranking e, posteriormente, teste post-hoc de Tukey, e foram analisados por médias de correlações de Spearman e curva ROC (receiver operating characteristic). O nível de significância adotado foi de 0.05. RESULTADOS Foram encontradas diferenças significativas entre os grupos quando comparados pré-eclâmpsia grave com hipertensão crônica e pré-eclâmpsia grave com controles (P < 0.0001 para ambas as medidas). CONCLUSÃO Natriúria pode estar reduzida na pré-eclâmpsia quando associada com calciúria. Avaliação da natriúria é um teste adicional para diagnóstico diferencial de doenças hipertensivas na gestação, mas é um pobre preditor quando utilizado isolado.

CONTEXT AND OBJECTIVE Sodium excretion abnormalities in preeclampsia have been studied in relation to several factors. The objective of this study was to compare natriuria (mEq/24 h) and calciuria levels (mg/24 h) in preeclamptic patients. DESIGN AND SETTING An analytical cross-sectional study with a control group was conducted in the obstetric center and the high-risk pregnancy outpatient clinic at a university hospital in southern Brazil, and in a primary healthcare unit in the same city, including pregnant women with mild preeclampsia, severe preeclampsia or chronic hypertension, and women with normal pregnancies (14 patients in each group). METHOD Natriuria was measured using an ion-selective electrode in an automated clinical chemistry analyzer (Hitache 917, Roche). All the patients collected 24-hour urine, at home or at the hospital, for analysis of proteins, creatinine, calcium, sodium and uric acid. Quantitative variables with asymmetrical distribution were described using the median, minimum and maximum, and were compared using the Kruskal-Wallis test. The results were logarithmically transformed, with one-way analysis of variance (ANOVA) by ranks and then the post-hoc Tukey test, and were analyzed by means of the Spearman correlation and receiver operating characteristic (ROC) curve. The significance level used was 0.05. RESULTS There were significant differences between the groups in comparing severe preeclampsia with chronic hypertension and severe preeclampsia with controls (P < 0.0001 for both measurements). CONCLUSION Natriuria levels may be lower in preeclampsia when associated with calciuria. Natriuria assessment is an additional test for differential diagnosis of hypertensive diseases in pregnancy, but is a poor predictor when used alone.
