Preeclampsia among women with COVID-19 during pregnancy and its impact on maternal and perinatal outcomes: Results from a national multicenter study on COVID in Brazil, the REBRACO initiative.

OBJECTIVE: To evaluate the prevalence of preeclampsia among cases of COVID-19 infection during pregnancy and the association between both conditions, in a multicenter cohort of Brazilian women with respiratory symptoms. STUDY DESIGN: Ancillary analysis of the Brazilian Network of COVID-19 in Obstetrics (REBRACO) study. We performed a nested case-control analysis selecting all women with COVID-19 and compared outcomes between women with and without PE. MAIN OUTCOMES: Maternal, gestational, and clinical characteristics and perinatal outcomes. MEASURES: Prevalence ratio (PR) and its 95%CI for each of the predictors and outcomes. RESULTS: A total of 203 women were included: 21 (10.3%) in PE group and 182 (89.7%) in non-PE group. Preeclampsia was not different among women with and without COVID-19 (10.3% vs 13.1%, p-value = 0.41), neither complication such as eclampsia and HELLP syndrome. Chronic hypertension (33.4%) (p < 0.01) and obesity (60.0%) (p = 0.03) were the most frequent comorbidities in PE group, and they were significantly more frequent in this group. Women with PE had more cesarean section (RR 5.54 [1.33 - 23.14]) and their neonates were more frequently admitted to neonatal intensive care unit (PR 2.46[1.06 - 5.69]), most likely due to preterm-birth-related complications. CONCLUSION: The prevalence of PE among women with COVID-19 infection during pregnancy was around 10%; women with COVID-19 and a history of chronic hypertension or obesity are more likely to have preeclampsia. Cesarean section is increased among women with PE and COVID-19, with increased rates of neonatal admission to intensive care units, mostly due to prematurity.

Clinical and epidemiological aspects of SARS-CoV-2 infection among pregnant and postpartum women in Mozambique: a prospective cohort study.

BACKGROUND: Although there is a significant increase of evidence regarding the prevalence and impact of COVID-19 on maternal and perinatal outcomes, data on the effects of the pandemic on the obstetric population in sub-Saharan African countries are still scarce. Therefore, the study aims were to assess the prevalence and impact of COVID-19 on maternal and neonatal outcomes in the obstetric population at Central Hospital of Maputo (HCM), Mozambique. METHODS: Prospective cohort study conducted at teaching and referral maternity, HCM, from 20 October 2020 to 22 July 2021. We collected maternal and perinatal outcomes up to 6 weeks postpartum of eligible women (pregnant and postpartum women-up to the 14th day postpartum) screened for COVID-19 (individual test for symptomatic participants and pool testing for asymptomatic). The primary outcome was maternal death, Severe Acute Respiratory Syndrome (SARS) and Intensive Care Unit (ICU) admission. We estimated the COVID-19 prevalence and the unadjusted RR (95% CI) for maternal and perinatal outcomes. We used the chi-square or Fisher's exact test to compare categorical variables (two-sided p-value < 0.05 for statistical significance). RESULTS: We included 239 participants. The overall prevalence of COVID-19 was 9.2% (22/239) and in the symptomatic group was 32.4% (11/34). About 50% of the participants with COVID-19 were symptomatic. Moreover, the most frequent symptoms were dyspnoea (33.3%), cough (28.6%), anosmia (23.8%), and fever (19%). Not having a partner, being pregnant, and alcohol consumption were vulnerability factors for SARS-CoV-2 infection. The risk of adverse maternal and neonatal outcomes (abortion, foetal death, preterm birth, Apgar, and NICU admission) was not significantly increased with COVID-19. Moreover, we did not observe a significant difference in the primary outcomes (SARS, ICU admission and maternal death) between COVID-19 positive and COVID-19 negative groups. CONCLUSION: The prevalence of COVID-19 in the obstetric population is higher than in the general population, and fifty percent of pregnant and postpartum women with COVID-19 infection are asymptomatic. Not having a partner and alcohol consumption were factors of greatest vulnerability to SARS-COV-2 infection. Moreover, being pregnant versus postpartum was associated with increased vulnerability to COVID-19. Data suggest that pregnant women with COVID-19 may have a higher frequency of  COVID-19 infection, reinforcing the need for universal testing, adequate follow-up for this population, and increasing COVID-19 therapy facilities in Mozambique. Moreover, provide counselling during Antenatal care for COVID-19 preventive measures. However, more prospective and robust studies are needed to assess these findings.

The COVID-19 pandemic in Brazilian pregnant and postpartum women: results from the REBRACO prospective cohort study.

Brazil presented a very high number of maternal deaths and evident delays in healthcare. We aimed at evaluating the characteristics of SARS-CoV-2 infection and associated outcomes in the obstetric population. We conducted a prospective cohort study in 15 Brazilian centers including symptomatic pregnant or postpartum women with suspected COVID-19 from Feb/2020 to Feb/2021. Women were followed from suspected infection until the end of pregnancy. We analyzed maternal characteristics and pregnancy outcomes associated with confirmed COVID-19 infection and SARS, determining unadjusted risk ratios. In total, 729 symptomatic women with suspected COVID-19 were initially included. Among those investigated for COVID-19, 51.3% (n = 289) were confirmed COVID-19 and 48% (n = 270) were negative. Initially (before May 15th), only 52.9% of the suspected cases were tested and it was the period with the highest proportion of ICU admission and maternal deaths. Non-white ethnicity (RR 1.78 [1.04-3.04]), primary schooling or less (RR 2.16 [1.21-3.87]), being overweight (RR 4.34 [1.04-19.01]) or obese (RR 6.55 [1.57-27.37]), having public prenatal care (RR 2.16 [1.01-4.68]), planned pregnancies (RR 2.09 [1.15-3.78]), onset of infection in postpartum period (RR 6.00 [1.37-26.26]), chronic hypertension (RR 2.15 [1.37-4.10]), pre-existing diabetes (RR 3.20 [1.37-7.46]), asthma (RR 2.22 [1.14-4.34]), and anaemia (RR 3.15 [1.14-8.71]) were associated with higher risk for SARS. The availability of tests and maternal outcomes varied throughout the pandemic period of the study; the beginning was the most challenging period, with worse outcomes. Socially vulnerable, postpartum and previously ill women were more likely to present SARS related to COVID-19.

Assessment of the availability of sexual and reproductive healthcare for Venezuelan migrant women during the SARS-CoV-2 pandemic at the north-western border of Brazil-Venezuela.

Background: The public healthcare system of Roraima state, at the north-western border Brazil-Venezuela, experienced an impact due to the incoming of Venezuelan migrants and to the SARS-CoV-2 (COVID-19) pandemic. After the beginning of the pandemic, the Brazilian government closed the border; however, migration continued through informal paths. There is scarce information regarding the availability of sexual and reproductive health (SRH) services at settings impacted both by migration and the COVID-19 pandemic. Consequently, we aimed to assess the availability and access to SRH services for Venezuelan migrant at Roraima state during the COVID-19 pandemic. Methods: We conducted a cross-sectional study with data collected during the pandemic using an electronic questionnaire. We interviewed three policy makers responsible for the directorate of primary care both at the municipal and state level; the directors of the two public hospitals and the two referral centres for women's health in Boa Vista, and in Pacaraima the director of the hospital and of the basic health post. We also interviewed 20 out of the 34 (58.8%) managers of the basic health posts in Boa Vista and 10 healthcare providers (physicians and nurses). Data collected covered issues pertaining to access to SRH services, and explored the impacts of the COVID-19 on continuation, access, and use of SRH services. Results: It was reported that 60% of the beds in the public sector were reallocated for COVID-19 cases and 26 out of the 34 (76%) health posts assessed interrupted the provision of SRH services, including contraceptive provision and gynaecological consultation, since these were considered not essential services. Most of the participants, (25/36; 69.4%) reported that both the state and the municipal health authorities implemented community outreach using telephone, social media, radio, and television, with guidance for the population on how to seek care using the healthcare network. Conclusions: The healthcare system in Roraima was impacted firstly by the need to provide SRH to a large number of Venezuelan migrant women, and after an effort to adapt to the reality that this migrant crisis posed; this system was affected by the needs to adapt to the COVID-19 pandemic.

Comparison of contraceptive sales before and during the COVID-19 pandemic in Brazil.

OBJECTIVE: The aim of the study was to assess the impact of the COVID-19 pandemic on sales of modern contraceptive methods in Brazil. METHODS: Monthly sales data were analysed of short-acting reversible contraceptive methods and long-acting reversible contraceptive (LARC) methods (implants and intrauterine contraception) and COVID-19 related deaths. Contraceptive methods were grouped as follows: emergency contraception (EC); oral contraception, vaginal rings and transdermal patches; injectable contraception; LARC methods including the copper intrauterine device (Cu-IUD); and LARC methods excluding the Cu-IUD. RESULTS: Contraceptive sales showed a non-significant increase in 2020 compared with the previous year; average sales ranged from 12.8 to 13.0 million units per month. Sales of injectable contraceptives increased between March and June 2020 and EC pills between June and July 2020; the variation in sales of pills, patches and rings was not significant. Sales of the levonorgestrel-releasing intrauterine system (LNG-IUS) and the etonogestrel (ENG) implant showed three patterns: a decrease in sales between February and May 2020 (coinciding with the closure of family planning services), an increase in sales after May 2020 (coinciding with the first COVID-19-related deaths), and a further increase in sales after July 2020 (corresponding to the increasing number of deaths from COVID-19). CONCLUSION: The COVID-19 pandemic has disrupted the Brazilian health care system. Since many family planning clinics were closed, sales of most modern contraceptives fell during 2020; however, the increase in sales of the LNG-IUS and ENG implant in the private sector indicates inequitable access to modern contraceptive methods.

Brazilian network of COVID-19 during pregnancy (REBRACO: a multicentre study protocol).

INTRODUCTION: The aim of this study was to evaluate the clinical, epidemiological and laboratory aspects of SARS-CoV-2 infection during pregnancy and postpartum in 16 maternity hospitals. METHODS AND ANALYSIS: A prospective multicentre study, with five axes. First, the prevalence of SARS-CoV-2 infection among women admitted for childbirth will be described in a cross-sectional study. Second, maternal and perinatal outcomes will be assessed in a prospective cohort study including pregnant or postpartum women with suspected COVID-19. Third, a cohort of positive COVID-19 cases with sampling of a variety of biological material. Histopathological and viral analysis of biological maternal and neonatal samples will be performed, and the assessment of nutritional variables to evaluate the association between vitamin D and severity of infection. Fourth, a monitoring and evaluation committee to collect relevant healthcare information and plan actions in centres facing the pandemic. Furthermore, qualitative studies will be performed to study pregnant women, their families and health professionals. Fifth, an ecological study will monitor the number of live births, stillbirths and other outcomes to explore any trend among the periods before, during and after the pandemic. Data will systematically be collected in an electronic platform following standardised operational procedures. For quantitative study components, an appropriate statistical approach will be used for each analysis. For qualitative data, in-depth interviews recorded in audio will be transcribed, checking the text obtained with the recording. Subsequently, thematic analysis with the aid of the NVivo programme will be performed. ETHICS AND DISSEMINATION: Ethical approval was obtained (letters of approval numbers 4.047.168, 4.179.679 and 4.083.988). All women will be fully informed to sign the consent form before enrolment in the study. Findings will be disseminated through peer-reviewed journals and scientific conferences.

Facing the COVID-19 pandemic inside maternities in Brazil: A mixed-method study within the REBRACO initiative.

INTRODUCTION: COVID-19 pandemic posed major challenges in obstetric health care services. Preparedness, development, and implementation of new protocols were part of the needed response. This study aims to describe the strategies implemented and the perspectives of health managers on the challenges to face the pandemic in 16 different maternity hospitals that comprise a multicenter study in Brazil, called REBRACO (Brazilian network of COVID-19 during pregnancy). METHODS: Mixed-method study, with quantitative and qualitative approaches. Quantitative data on the infrastructure of the units, maternal and perinatal health indicators, modifications on staff and human resources, from January to July/2020. Also, information on total number of cases, and availability for COVID-19 testing. A qualitative study by purposeful and saturation sampling was undertaken with healthcare managers, to understand perspectives on local challenges in facing the pandemic. RESULTS: Most maternities early implemented their contingency plan. REBRACO centers reported 338 confirmed COVID-19 cases among pregnant and post-partum women up to July 2020. There were 29 maternal deaths and 15 (51.8%) attributed to COVID-19. All maternities performed relocation of beds designated to labor ward, most (75%) acquired mechanical ventilators, only the minority (25%) installed new negative air pressure rooms. Considering human resources, around 40% hired extra health professionals and increased weekly workload and the majority (68.7%) also suspended annual leaves. Only one center implemented universal screening for childbirth and 6 (37.5%) implemented COVID-19 testing for all suspected cases, while around 60% of the centers only tested moderate/severe cases with hospital admission. Qualitative results showed that main challenges experienced were related to the fear of the virus, concerns about reliability of evidence and lack of resources, with a clear need for mental health support among health professionals. CONCLUSION: Study findings suggest that maternities of the REBRACO initiative underwent major changes in facing the pandemic, with limitations on testing, difficulties in infrastructure and human resources. Leadership, continuous training, implementation of evidence-based protocols and collaborative initiatives are key to transpose the fear of the virus and ascertain adequate healthcare inside maternities, especially in low and middle-income settings. Policy makers need to address the specificities in considering reproductive health and childbirth during the COVID-19 pandemic and prioritize research and timely testing availability.
