Management and Prevention of COVID-19 in Pregnancy and Pandemic Obstetric Care: A Review of Current Practices

Tracking excess of maternal deaths associated with COVID-19 in Brazil: a nationwide analysis

BACKGROUND

The COVID-19 pandemic brought a new challenge to maternal mortality in Brazil. Throughout 2020, Brazil registered 549 maternal deaths, mainly in second and third-trimester pregnant women. The objective of this study was to estimate the excess maternal deaths in Brazil caused directly and indirectly by Covid-19 in the year 2020. In addition, we sought to identify clinical, social and health care factors associated with the direct maternal deaths caused by Covid-19.

METHODS

We performed nationwide analyses based on data from the Mortality Information System (SIM) for general and maternal deaths and the Influenza Epidemiological Surveillance System (SIVEP-Influenza) for estimates of female and maternal deaths due to COVID-19. Two distinct techniques were adopted. First, we describe maternal deaths directly caused by covid-19 and compare them with the historical series of deaths from covid-19 among women of childbearing age (15 to 49 years). Next, we estimated the total excess maternal mortality. Then, we calculated odds ratios for symptoms, comorbidities, social determination proxies and hospital care aspects between COVID-19 maternal deaths and deaths of women of childbearing age who were not pregnant or no maternal deaths. We chose women of childbearing age (15 to 49 years) as a reference because sex and age introduce differentials in the risk of COVID-19 death.

RESULTS

Most maternal deaths occurred during pregnancy compared to postpartum deaths month by month in 2020 (μ = 59.8%, SD = 14.3%). The excess maternal mortality in 2020 in Brazil was 1.40 (95% CI 1.35-1.46). Even considering excess mortality due to COVID-19 for the childbearing age female population (MMR 1.14; 95% CI 1.13-1.15), maternal mortality exceeded the expected number. The odds of being a black woman, living in a rural area and being hospitalized outside the residence municipality among maternal deaths were 44, 61 and 28% higher than the control group. Odds of hospitalization (OR 4.37; 95% CI 3.39-5.37), ICU admission (OR 1.73; 95% CI 1.50-1.98) and invasive ventilatory support use (OR 1.64; CI 95% 1.42-1.86) among maternal deaths were higher than in the control group.

CONCLUSIONS

There was excess maternal mortality in 2020 in Brazil. Even with adjustment for the expected excess mortality from Covid-19 in women of childbearing age, the number of maternal deaths exceeds expectations, suggesting that there were deaths among pregnant and postpartum women indirectly caused by the pandemic, compromising access to prenatal care., adequate childbirth and puerperium.

Epidemiologia do HIV em gestantes e sua relação com o período da pandemia de COVID-19

RESUMO Objetivo: Analisar, à luz da Teoria Social Ecológica, a evolução dos casos notificados de HIV na gestação em um estado brasileiro e sua relação com o início da pandemia de COVID-19. Método: Estudo retrospectivo, com amostra composta por todas as notificações de HIV gestacional do estado do Ceará - Brasil no período de 2017 a 2021, na plataforma IntegraSUS. A coleta de dados foi realizada em janeiro de 2022. As variáveis analisadas foram organizadas de acordo com os níveis teóricos: macrossistema, exossistema, mesossistema e microssistema. Resultados: Foram registrados 1.173 casos de HIV em gestantes. Ao comparar o período pré e pós-pandemia, observou-se redução da taxa de detecção da doença (de 231 para 122,67 gestantes) e 1,82 vezes mais chances de as mulheres não usarem antirretrovirais no parto após o início da pandemia. Houve redução de 55% de partos vaginais e de 39% de cesarianas das mulheres com diagnóstico de HIV após o início da pandemia. Conclusão A pandemia de COVID-19 causou impacto epidemiológico e assistencial, levando a uma redução do número de notificações e taxa de detecção de gestantes que vivem com HIV no estado do Ceará. Logo, reforça-se a necessidade de assegurar a cobertura de atenção à saúde, com ações de diagnóstico precoce, garantia de tratamento e uma assistência pré-natal de qualidade.

Impact of the COVID-19 Pandemic on Obstetric Interventions at a Public Hospital

INTRODUCTION

In response to the COVID-19 pandemic, health systems quickly implemented changes in care delivery with a goal of balancing patient-focused obstetric care with the need to protect pregnant persons and health care providers from infection. Yet, there is no consensus within the scientific community on the impact these measures have on obstetric outcomes in vulnerable populations. We aimed to assess the impact of the COVID-19 pandemic on rates of obstetric procedures and severe maternal morbidity (SMM) among births at an urban safety net institution.

METHODS

We used an interrupted time series design to calculate risk ratios (RRs) and 95% confidence intervals (CIs) comparing monthly rates of labor induction, cesarean births (overall and among nulliparous, term, singleton, vertex births), operative vaginal births, and SMM among births occurring at a public hospital before (March 1, 2016, to February 29, 2020) and during (March 1, 2020, to May 31, 2021) the COVID-19 pandemic.

RESULTS

There were 10,714 and 2,736 births in the prepandemic and postpandemic periods, respectively. Overall, the rates of obstetric interventions and SMM were constant over the two time periods. There were no significant differences in rates of labor induction (42% during prepandemic period vs. 45% during pandemic period; RR, 1.12; 95% CI, 0.93-1.34), operative vaginal births (5% vs. 6%; RR, 1.24; 95% CI, 0.88-1.76), cesarean births (28% vs. 33%; RR, 1.10; 95% CI, 0.94-1.28), or nulliparous, term, singleton, vertex cesarean births (24% vs. 31%; RR, 1.27; 95% CI, 0.92-1.74). Rates of SMM (7% vs. 8%; RR, 1.19; 95% CI, 0.86-1.65) were also unchanged.

CONCLUSIONS

Our findings indicate that the rapid implementation of measures to reduce viral transmission in the labor and delivery setting did not materially affect routine clinical management or rates of serious maternal complications.

Epidemiology of HIV in pregnant women and its relationship with the period of the COVID-19 pandemic

OBJECTIVE

To analyze, in the light of the Social Ecological Theory, the progression of reported cases of HIV during pregnancy in a Brazilian state and their relationship with the onset of the COVID-19 pandemic.

METHOD

Retrospective study, with a sample consisting of all reports of gestational HIV in the state of Ceará - Brazil from 2017 to 2021, on the IntegraSUS platform. Data collection was carried out in January 2022. The analyzed variables were organized according to the theoretical levels: macrosystem, exosystem, mesosystem, and microsystem.

RESULTS

A total of 1,173 cases of HIV in pregnant women were recorded. When comparing the pre- and post-pandemic period, a reduction in the disease detection rate (from 231 to 122.67 pregnant women) was observed, as well as 1.82 times more chances of women not using antiretrovirals during childbirth after the start of the pandemic. There was a 55% reduction in vaginal births and 39% in cesarean sections among women diagnosed with HIV after the start of the pandemic.

CONCLUSION

The COVID-19 pandemic had an epidemiological and care impact, leading to a reduction in the number of notifications and in the detection rate of pregnant women living with HIV in the state of Ceará. Therefore, the need to ensure health care coverage is emphasized, with early diagnosis actions, guaranteed treatment, and quality prenatal care.

COVID-19 and Pregnancy

It is of greatest concern how COVID-19 is affecting pregnancy, mothers, and babies. Scientists are studying the impact of COVID-19 on pregnant women and babies and are understanding a little more every day. Reports show that there is an increased risk in pregnant women compared to nonpregnant women to get more serious illness due to COVID-19. Researchers are also investigating COVID-19 and its potential impact on a fetus. There are exceedingly rare cases of COVID-19 transmission to the fetus, and newborns can pick up COVID-19 when exposed. Vaccines are proved to be safe for pregnant women and help prevent both mother and the fetus from getting COVID-19 and are also highly effective to prevent COVID-19 infection, critical sickness, and fatalities in general. There are specific guidelines for labor and delivery during the COVID-19 pandemic which are to be imposed and followed to achieve safer and healthier childbirth. In this article, the overall influence of COVID-19 in pregnancy, its pathophysiology, effects on placenta and neonates, maternal and perinatal features and outcomes, the role of vaccination, available treatment options, and the guidelines to be followed during the pandemic are discussed based on the available scientific evidence.

Protecting Breastfeeding during the COVID-19 Pandemic: A Scoping Review of Perinatal Care Recommendations in the Context of Maternal and Child Well-Being

The objective of this scoping review is to determine to what extent the recommendations on perinatal care protect breastfeeding during the COVID-19 pandemic. The review follows the PRISMA ScR Extension guidelines. The research was conducted in Scopus, Medline via Pubmed, and Web of Science databases from 1 March 2020 to 31 May 2021, using 392 combinations of keywords. We searched for reviews and original papers published in English providing recommendations on delivery mode, companion during labor, the possibility of skin-to-skin contact (SSC), breastfeeding, and visitors policy. After screening, 86 out of 8416 publications qualified for data extraction. The majority of them indicated that COVID-19 infection is not a sufficient reason for a cesarean section; however, on a national level, cesarean births in severely ill patients were overrepresented. A significant number of recommendations deprived mothers of the necessary support during their labor and stay in the maternity ward. A shared decision-making model was hardly visible. Only the earliest COVID-19 recommendations suspended direct breastfeeding; in later publications, decisions were related to the mother's health, but other options of natural feeding were rarely discussed.

Effects of the COVID-19 pandemic on perinatal outcomes: a retrospective cohort study from Turkey

Background

Lockdowns, pregnant women’s fear from hospitalization in addition to uncertainties about appropriate birthing practices at the beginning of the pandemic may have affected the health outcomes of mother-infant couples. We aimed to explore whether pregnancy outcomes including the rates of cesarean delivery (CS), preterm, and low birth weight (LBW) births have changed during the pandemic period compared with the pre-pandemic period.

Methods

We applied a population-based retrospective cohort, before-after approach in 2020 vs. similar calendar months in 2019 for five periods [Jan-Feb (pre-pandemic); March–May (1st wave and lockdown); June–August; September–October; November–December (2nd wave and lockdown)]. The data was modelled through multiple logistic regressions using key outcomes; CS, preterm, and LBW births as the dependent variables, and adjustments were made for independent variables in SPSS software. We evaluated the modification of years by periods by adding interaction term (yearXperiod) to the model.

Results

The rate of CS in hospital births increased from 57.7% in 2019 to 60.2% in 2020. CS rates were significantly increased during the 3rd and 4th periods. The overall preterm rate was 11%. When singleton pregnancies were considered, adjusted multivariable analyses showed a decrease in preterm proportions during all time periods with respect to the pre-pandemic period. The percentage of LBW was 7.7% during the pandemic period and was found to be significantly reduced compared to the pre-pandemic period. There was a significant reduction in LBW rates in all periods except the second lockdown period.

Conclusions

Our findings suggested significant reductions in preterm and LBW births possibly due to the indirect effects of the pandemic. Moreover, strategies need to be considered to address the increased CS rates and shifting of maternity service utilization to private facilities.

The impact of COVID-19 in pregnancy: Part II. Vaccination to pregnant women

Effective strategies are urgently needed to decrease the risk of untoward outcomes of pregnant women with severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) infection. Pregnant women are a vulnerable population to infectious disease pandemics with dramatically increased infectious diseases-related serious complications, such as the need of hospitalizations, the need of admission to intensive care unit, and the final disease-related death compared with those nonpregnant counterparts or those pregnant women without infection. Several studies have shown that vaccinations in pregnancy are a safe and highly effective strategy, not only for pregnant women but also for fetus and/or newborn because of the passive transplacental transfer of antibodies to the offspring. Active and passive prevention of infectious diseases is approved as effective strategies for women who attempt to become pregnant or during pregnancy. Despite the large and proven scientific evidence, pregnant women still puzzle over whether they should get vaccinated. The question therefore arises: Why are pregnant women so reluctant to receive vaccination? The explanation is more likely in the way that the benefits of vaccination have been communicated "confusedly." In fact, like virtually all clinical trials, all the COVID-19 vaccine trials have excluded pregnant and lactating women from participating, contributing to uncertainty of safety and efficacy in COVID-19 vaccines that have been well prepared and available for the general adult population worldwide. Moreover, messenger RNA vaccine is a relatively brand-new vaccine, and experience with this type of vaccine is still scarce. It is hard to overcome this innovation deadlock. The knowledge and awareness of pregnant women who are at risk, and full information on the knowledge of vaccines and related preventable diseases in pregnant women may avoid hesitancy and increase vaccine acceptance. The current review is a part two addressing the impact of COVID-19 on pregnant women. We focus on the up-to-date information about the application of vaccination on pregnant women, especially during this COVID-19 pandemic.

Maternal and fetal outcomes of the pregnant woman with COVID-19: The first case report in Taiwan

OBJECTIVE

A real-Taiwan experience to deal with near-term pregnant woman infected by severe acute respiratory syndrome coronavirus 2, SARS-CoV-2 (coronavirus disease 2019, COVID-19) is extremely limited. We described the first case in Taiwan.

CASE REPORT

A 30-year-old woman, primigravida had a laboratory-confirmed COVID-19 infection at 36 gestational weeks (GW). She was asymptomatic. Ten days later, she was hospitalized and receive a selective cesarean section with a term baby weighted 3142 gm (Apgar score 8 and 9 at 1st and 5th minute, respectively) at 38 GW. No evidence of in utero and direct transmission was found and newborn was free of COVID-19.

CONCLUSION

It is still uncertain whether timing or mode of delivery is appropriate in SARS-CoV-2 infected pregnant woman in near term, but we suggested that a selective delivery time at 38 GW or later, regardless of which mode of delivery is finally decided, can be considered.

A symptomatic near-term pregnant woman recovered from SARS-CoV-2 infection

OBJECTIVE

Coronavirus-2019 (COVID-19) is a global health crisis. Although pregnant women are a vulnerable population during the infectious pandemics, extremely rare cases of pregnant women infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are described in Taiwan. We share our experience to manage a pregnant women with COVID-19 in the third trimester and subsequent delivery at term.

CASE REPORT

A 43-year-old woman presented with sore throat, cough and rhinorrhea was diagnosed as laboratory-confirmed SARS-CoV-2 infection at the 35 gestational weeks (GW). During the hospitalization, the disease progressed with a need of oxygen supplement and prednisolone therapy. She was discharged uneventfully at 37 GW. Finally, she delivered a female baby with Apgar score of 8-9 points at 38 GW by cesarean section due to the deformity of pelvic cavity resulted from previous surgery for pelvic bone tumor. Both mother and her offspring (without SARS-CoV-2 infection) were discharged uneventfully.

CONCLUSION

Our report adds the growing body of experience toward management of pregnant women with SARS-CoV-2 infection. Decision making of timing and method of delivery is regarding to individualized condition and hospital setting.

The impact of COVID-19 in pregnancy: Part I. Clinical presentations and untoward outcomes of pregnant women with COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease 2019, COVID-19) is a pandemic disease with rapidly and widely disseminating to the world. Based on experiences about the H1N1, Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) coronavirus pandemics, pregnant women who are infected are disproportionately more likely to develop severe illness and need more hospitalizations, intensive care, and finally die of diseases compared with those nonpregnant counterparts or those pregnant women without infection. Although more than one half of pregnant women with COVID-19 are asymptomatic, and as well as their symptoms are frequently mild, this observation presents a further challenge regarding service provision, prevention, and management, in which this may result in overlooking the risk of COVID-19 during pregnancy. As predictable, despite much advance in critical care in recent decades, during the 2020 COVID-19 pandemic, pregnant women with COVID-19 are really at higher risk to progress to severe illness; require hospitalization; need intensive care, such as the use of mechanical ventilation as well as extracorporeal membrane oxygenation (ECMO), and of most important, die than their nonpregnant counterparts and pregnant women without COVID-19. The magnitude of the risk to pregnant women further extend to their newborn from COVID-19 with resultant significantly increasing perinatal and neonatal morbidity and mortality rates. The heightened risk of untoward outcomes in pregnant women emphasizes an urgent need of national or international recommendations and guidelines to optimize prevention and management strategies for COVID-19 in pregnancy. Active and passive prevention of COVID-19 is approved as effective strategies for women who attempt to be pregnant or during pregnancy. Understanding that pregnant women who are a vulnerable population is essential to improve the care in the novel and urgent COVID-19 pandemic. The current review is a part I to summarize the up-to-date information about the impact of laboratory-confirmed SARS-CoV-2 infection on pregnant women and focus on clinical presentations and untoward pregnancy outcomes of these pregnant women infected with SARS-CoV-2.

Viral respiratory infections and psychosis: A review of the literature and the implications of COVID-19

The historical association between respiratory infections and neuropsychiatric symptoms dates back centuries, with more recent literature highlighting a link between viral infections and schizophrenia. Maternal influenza infection during pregnancy has been associated with the development of schizophrenia in offspring. Viral infections in neonates, children, and adolescents have also been associated with later development of schizophrenia. Neuroinvasive and/or systemic infections are thought to increase risk for psychopathology via inflammatory mechanisms, particularly when exposure occurs during critical neurodevelopmental windows. Several human coronaviruses (HCoVs) have been associated with psychotic disorders and increasing reports of the neuropsychiatric manifestations of COVID-19 suggest it has neuroinvasive properties similar to those of other HCoVs. These properties, in conjunction with its ability to generate a massive inflammatory response, suggest that COVID-19 may also contribute to future psychopathology. This review will summarize the psychopathogenic mechanisms of viral infections and discuss the neuroinvasive and inflammatory properties of COVID-19 that could contribute to the development of psychotic disorders, with a focus on in utero, neonatal, and childhood exposure.
