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.

ABSTRACT Objective: The aim of the study was to assess the impact of the Gamma coronavirus disease 2019 (COVID-19) variant on pregnant and postpartum women with Cardiovascular Disease (CVD). Methods: The Influenza Epidemiological Surveillance System database (SIVEP-Gripe), a compulsory notification system for cases of Severe Acute Respiratory Syndrome (SARS), was investigated for notified cases of pregnant and postpartum women with reported CVD and SARS due to COVID-19 between February 16, 2020 and May 1, 2021 (when vaccination began), was investigated. In this retrospective cohort, two groups were formed based on symptom onset date, according to the predominance of the variants: original (group 2020) and Gamma (group 2021). Cases with missing information on the presence or absence of CVD were excluded. The comparative analysis was controlled for confounding variables. Results: Among 703 COVID-19 cases notified with CVD (406 patients in 2020 and 297 patients in 2021), compared to 2020, cases in 2021 had more respiratory symptoms (90.6 % vs. 80.1 %, p < 0.001), greater ventilatory support need (75.3 % vs. 53.9 %, p < 0.001), more ICU admission (46.6 % vs. 34.3 %, p = 0.002), longer duration (20.59 ± 14.47 vs. 16.52 ± 12.98 days, p < 0.001), higher mortality (25.6 % vs. 15.5 %, p < 0.001), with more than two-times mortality likelihood in the third trimester (adjusted OR = 2.41, 95 % CI 1.50–3.88, p < 0.001) or puerperium periods (adjusted_OR = 2.15, 95 % CI 1.34-3.44, p = 0.001). Conclusions: In Brazil, pregnant and postpartum women with CVDs in the Gamma variant phase have higher morbidity and mortality than those affected by the original variant of Coronavirus-19.

Resumo Objetivo O objetivo do presente estudo foi comparar a história obstétrica e os parâmetros bi- e tridimensionais ultrassonográficos de acordo com os diferentes comprimentos cervicais. Métodos O presente estudo transversal analisou 248 gestantes no segundo trimestre de acordo com o comprimento cervical e comparou os dados com a história obstétrica e os parâmetros ultrassonográficos 2D/3D. As pacientes foram divididas em 3 grupos de acordo com o comprimento do colo uterino: grupo Colo Curto para comprimentos cervicais ≥ 15mm e < 25mm (n = 68), grupo Colo Muito Curto para comprimentos cervicais < 15mm (n = 18) e grupo Controle, composto por 162 gestantes com comprimento cervical uterino ≥ 25 mm. Resultados Ao analisar a história obstétrica apenas de pacientes não nulíparas, foi relatadauma associação significativa entre a presença de colo uterino curto na gravidez atual e pelo menos um episódio de parto prematuro anterior (p = 0,021). Comprimento e volume do colo uterino foram correlacionados positivamente (coeficiente de Pearson = 0,587, p < 0,0001). O parâmetro índice de fluxo (IF) da vascularização cervical foi significativamente diferente entre os grupos Controle e Colo Muito Curto. Entretanto, após regressão linear, na presença de informações de volume, não encontramos associação entre os grupos e o parâmetro IF. Também não foi encontrada relação entre o Doppler da artéria uterina e o encurtamento cervical. Conclusão O presente estudo mostrou uma associação significativa entre a presença de colo uterino curto na gravidez atual e pelo menos um episódio de parto prematuro anterior. Nenhum dos índices de vascularização se correlaciona com o comprimento cervical como parâmetro independente, assim como o Doppler da artéria uterina também não está relacionado ao comprimento do colo uterino.

Abstract Objective The aim of the present study was to compare the obstetric history and both two- and tri-dimensional ultrasound parameters according to different cervical lengths. Methods The present cross-sectional study analyzed 248 midtrimester pregnant women according to cervical length and compared the data with the obstetric history and 2D/3D ultrasound parameters. Patients were divided into 3 groups according to cervical length: The Short Cervix group for cervical lengths ≥ 15mm and< 25mm(n= 68), the Very Short Cervix group for cervical lengths< 15mm (n = 18) and the Control group, composed of 162 pregnant women with uterine cervical lengths ≥ 25mm. Results When analyzing the obstetric history of only non-nulliparous patients, a significant association between the presence of a short cervix in the current pregnancy and at least one previous preterm birth was reported (p = 0.021). Cervical length and volume were positively correlated (Pearson coefficient = 0.587, p < 0.0001). The flow index (FI) parameter of cervical vascularization was significantly different between the Control and Very Short Cervix groups. However, after linear regression, in the presence of volume information, we found no association between the groups and FI. Uterine artery Doppler was also not related to cervical shortening. Conclusion The present study showed a significant association between the presence of a short cervix in the current pregnancy and at least one previous preterm birth. None of the vascularization indexes correlate with cervical length as an independent parameter. Uterine artery Doppler findings do not correlate with cervical length.

RESUMO OBJETIVO: Os resultados gestacionais e neonatais de mulheres com cervicodilatação precoce submetidas à cerclagem de emergência foram avaliados e comparados com mulheres tratadas com manejo expectante com repouso no leito. MÉTODOS: Análise retrospectiva de gestantes admitidas entre 2001 e 2017 com diagnóstico de cervicodilatação precoce e/ou membranas protrusas. Foram incluídas pacientes com gestação única de feto sem malformações, entre 16 semanas e 25 semanas e 6 dias, com dilatação cervical de 1 a 3 cm; as pacientes que tiveram parto ou aborto dentro de 2 dias após admissão foram excluídas. RESULTADOS: O estudo envolveu 30 pacientes: 19 no grupo cerclagem e 11 no grupo repouso. Houve diferença significativa, com o grupo cerclagem apresentando melhores resultados em relação à idade gestacional no parto (28,7 vs. 23,3 semanas; p=0,031) e à latência entre a admissão hospitalar e o parto (48,6 vs. 16 dias; p=0,016). A taxa de mortalidade fetal foi menor no grupo cerclagem (5,3% vs. 54,5%, p=0,004). Considerando a idade gestacional no nascimento dos recém-nascidos vivos, não houve diferença entre os grupos cerclagem e expectante (29,13 vs. 27,4 semanas; p=0,857). CONCLUSÕES: A cerclagem de emergência foi associada a maior período de latência com impacto significativo na idade gestacional do parto e à redução da taxa de mortalidade fetal.

SUMMARY BACKGROUND: The gestational and neonatal outcomes of women with early cervical dilatation undergoing emergency cerclage were evaluated and compared with women treated with expectant management and bed rest. METHODS: Retrospective analysis of pregnant women admitted between 2001 and 2017 with a diagnosis of early cervical dilatation and/or bulging membranes. Patients with a singleton pregnancy of a fetus without malformations, between 16 and 25 weeks and 6 days, with cervical dilatation of 1 to 3 cm were included; patients who delivered or miscarried within 2 days after admission were excluded. RESULTS: The study enrolled 30 patients: 19 in the cerclage group and 11 in the rest group. There was a significant difference, with the cerclage group showing better results concerning gestational age at delivery (28.7 vs. 23.3 weeks; p=0.031) and latency between hospital admission and delivery (48.6 vs. 16 days; p=0.016). The fetal death rate was lower in the cerclage group (5.3% vs. 54.5%, p=0.004). Considering gestational age at delivery of live newborns, no difference was observed between the cerclage and rest groups (29.13 vs. 27.4 weeks; p=0.857). CONCLUSIONS: Emergency cerclage was associated with longer latency, a significant impact on gestational age at delivery and reduction in the fetal death rate.

Since studies show that an unfavorable environment during intrauterine development predisposes individuals to several diseases in adulthood, our objective is to assess the relation between fetal growth restriction and chronic renal disease in adults. We searched four different electronic databases through November 2017: CENTRAL, EMBASE, LILACS and MEDLINE. We selected studies with longitudinal or transversal designs associating kidney function in adulthood with low birth weight. Two reviewers evaluated the inclusion criteria and the risk of bias and extracted data from the included papers. Thirteen studies were selected for the systematic review and meta-analysis. We observed increased risks of presenting end-stage renal disease (risk ratio 1.31, 95% confidence interval: 1.17, 1.47), a lower glomerular filtration rate (ml/min) (mean difference 7.14; 95% confidence interval: -12.12, -2.16), microalbuminuria (risk ratio 1.40; 95% confidence interval: 1.28, 1.52) and a small increase in the albumin/creatinine ratio (mean difference 0.46; 95% confidence interval: 0.03, 0.90) in the low birth weight patients, compared with control group. These findings suggest that low birth weight is associated with renal dysfunction in adults.

OBJECTIVES: To analyze the influence of lying in prone position on a specially designed stretcher on the maternal-fetal hemodynamic parameters and comfort of pregnant women. METHODS: A randomized, controlled trial with 33 pregnant women divided into 2 groups: pregnant group sequence 1 and pregnant group sequence 2. The order of positions used in sequence 1 was Fowler’s position, prone position, supine position, left lateral, Fowler’s position 2, supine position 2, prone position 2 and left lateral 2. The order of positions used in sequence 2 was Fowler’s position, prone position, left lateral, supine position, Fowler’s position 2, left lateral 2, prone position 2 and supine position 2. Each woman remained in each position for 6 minutes. For the statistical analyses, we used Wilcoxon’s test for 2 paired samples when comparing the prone position with the other positions. The variables are presented in graphs showing the means and 95% confidence intervals. Trial Registration: Clinical Trial No. ISRCTN41359519 RESULTS: All the parameters were within the standards of normality. There were no differences between positions in terms of maternal heart rate, diastolic blood pressure, oxygen saturation and fetal heart rate. However, there were significant decreases in respiratory rate and systolic blood pressure in prone position 2 compared with left lateral 2. There was an increase in oxygen saturation in prone position compared with Fowler’s position and supine position 2 in both sequences. All the women reported feeling comfortable in the prone position. CONCLUSIONS: The prone position was considered safe and comfortable and could be advantageous for improving oxygen saturation and reducing the systolic blood pressure and respiratory rate.
