Maternal and neonatal safety outcomes after SAR-CoV-2 vaccination during pregnancy: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: More than five million individuals died because of problems connected to COVID-19. SARS-Cov-2 poses a particular challenge to expectant mothers, who comprise one of the most vulnerable segments of the population. Our aim is to demonstrate the maternal and neonatal safety of the COVID-19 vaccine during pregnancy. METHODS: We searched PubMed, Cochrane Library, Scopus, Web of Science (WOS), Embase, Ovid, MedRxiv, and BioRxiv databases from inception till December 2021 and then updated it in April 2022. Additionally, we searched ClinicalTrials.gov, Research Square and grey literature. Cohort, case-control studies, and randomized controlled trials detecting the safety of the Covid-19 vaccine during pregnancy were included. We used the Cochrane tool and Newcastle-Ottawa Scale to assess the risk of bias of the included studies and the GRADE scale to assess the quality of evidence. A meta-analysis was conducted using review manager 5.4. RESULTS: We included 13 studies with a total number of 56,428 patients. Our analysis showed no statistically significant difference in the following outcomes: miscarriage (1.56% vs 0.3%. RR 1.23; 95%CI 0.54 to 2.78); length of maternal hospitalization (MD 0.00; 95%CI -0.08 to 0.08); puerperal fever (1.71% vs 1.1%. RR 1.04; 95%CI 0.67 to 1.61); postpartum hemorrhage (4.27% vs 3.52%. RR 0.84; 95%CI 0.65 to 1.09); instrumental or vacuum-assisted delivery (4.16% vs 4.54%. RR 0.94; 95%CI 0.57 to 1.56); incidence of Apgar score ≤ 7 at 5 min (1.47% vs 1.48%. RR 0.86; 95%CI 0.54 to 1.37); and birthweight (MD -7.14; 95%CI -34.26 to 19.99). CONCLUSION: In pregnancy, the current meta-analysis shows no effect of SAR-CoV-2 vaccination on the risk of miscarriage, length of stay in the hospital, puerperal fever, postpartum hemorrhage, birth weight, or the incidence of an Apgar score of ≤ 7 at 5 min.

Antenatal Classes in the Context of Prenatal Anxiety and Depression during the COVID-19 Pandemic.

Perinatal maternal anxiety and depression negatively affect intrauterine fetal development, birth outcome, breastfeeding initiation, duration, and milk composition. Antenatal classes potentially reduce the anxiety of pregnant women and may thus contribute to healthy infant development. The study investigates the relationship between participation in online or in-person antenatal classes and levels of anxiety and depression in Polish women during the COVID-19 pandemic. The study group included 1774 adult, non-smoking pregnant women. We compared the state anxiety (STAI-State) and depression levels (EPDS) in women who (i) attended antenatal classes in-person, (ii) attended online classes, and (iii) did not attend any of them. The statistical analyses included a GLM model and trend analysis, while controlling for maternal trait anxiety, age, pregnancy complications, trimester of pregnancy, previous pregnancies, and COVID-19 infections. We observed statistically significant differences in the level of anxiety (and depression). Women who did attend antenatal classes in person had the lowest levels of anxiety and depression. Considering the importance of maternal mental well-being on fetal development, birth outcome, and breastfeeding, in-person participation in antenatal classes should be recommended to pregnant women.

Pregnancy and neurologic complications of COVID-19: A scoping review.

While neurologic complications are frequently reported among patients with COVID-19 in the general population, they are unknown in pregnant women. This paper summarizes the case reports of pregnant women with confirmed SARS-CoV-2 infection plus a specified neurologic diagnosis. Until November 2021, 18 case reports were found. Both the central and peripheral nervous systems were equally affected: delirium (n = 1), posterior reversible encephalopathy syndrome (n = 4), cerebrovascular disease (n = 2), acute cerebral demyelinating disease (n = 1), acute necrotizing encephalopathy (n = 1), Guillain-Barré syndrome (n = 5), including one patient who also had vestibular neuritis, Bell's palsy (n = 3), and rhabdomyolysis (n = 1). The median maternal age was 32.5 (25-35) years, the median gestational age was 34 (30-36.5) weeks, and 38.9% presented previous medical conditions. Respiratory symptoms were reported in 76.5%, and 76.5% received immunotherapies to treat the COVID-19 or the neurologic complications. Half the women required admission to ICU and, more often, were those with central nervous system involvement (77.8% vs. 22.2%; Chi-square test, p = .018). For 64.7% of women, the most common method of delivery was surgical, although just one case was due to the neurologic complication. There were reports of one spontaneous abortion, two fetal deaths, and no maternal deaths. Only one case presented a poor neurologic outcome. It is possible that our findings are underestimated, considering that there are thousands of reports regarding neurologic complications in the general population with COVID-19.

Frequency and source of worries in an International sample of pregnant and postpartum women during the Covid-19 pandemic.

BACKGROUND: Pregnant and postpartum women face unique challenges and concerns during the COVID-19 pandemic. Thus far, no studies have explored the factors associated with increased levels of worry in this population globally. The current study sought to assess the frequency and sources of worry during the COVID-19 pandemic in an international sample of pregnant and postpartum women. METHODS: We conducted an anonymous, online, cross-sectional survey in 64 countries between May and June 2020. The survey was available in 12 languages and hosted on the Pregistry platform for COVID-19 studies. Participants were sought mainly on social media platforms and online parenting forums. The survey included questions related to demographics, level of worry, support, stress, COVID-19 exposure, frequency of media usage, and mental health indicators. RESULTS: The study included 7561 participants. Eighty-three percent of all participants indicated that they were either 'somewhat' or 'very' worried. Women 13-28 weeks pregnant were significantly more likely to indicate that they were 'very worried' compared to those who were postpartum or at other stages of pregnancy. When compared with women living in Europe, those in Africa, Asia and Pacific, North America and South/Latin America were more likely to have increased levels of worry, as were those who more frequently interacted with social media. Different forms of support and stress also had an impact upon level of worry, while indicators of stress and anxiety were positively associated with worry level. CONCLUSION: Pregnant and postpartum women are vulnerable to the changes in societal norms brought about by the COVID-19 pandemic. Understanding the factors associated with levels of worry within this population will enable society to address potential unmet needs and improve the current and future mental health of parents and children.

Adverse Maternal and Fetal Outcomes in a Novel Experimental Model of Pregnancy after Recovery from Renal Ischemia-Reperfusion Injury.

BACKGROUND: Recent clinical studies report that women with a history of AKI have an increased incidence of maternal and fetal adverse outcomes during pregnancy, despite fully recovering renal function prior to conception. The mechanisms contributing to such adverse outcomes in pregnancy after AKI are not yet understood. METHODS: To develop a rodent model to investigate fetal and maternal outcomes in female animals with a history of AKI, we used ischemia-reperfusion injury as an experimental model of AKI in female Sprague Dawley rats. The 12-week-old animals underwent warm bilateral ischemia-reperfusion surgery involving clamping of both renal arteries for 45 minutes or sham surgery (control). Rats were allowed to recover for 1 month prior to mating. Recovery from ischemia-reperfusion injury was confirmed by measurements of plasma creatinine and urinary protein excretion. We assessed maternal and fetal outcomes during late pregnancy on gestational day 20. RESULTS: After recovery from ischemia-reperfusion injury, compared with healthy sham-surgery controls, dams exhibited pregnancy-induced renal insufficiency with increases in plasma creatinine and urea, along with increased urinary protein excretion. Additionally, recovered ischemia-reperfusion dams experienced worse fetal outcomes compared with controls, with intrauterine growth restriction leading to higher rates of fetal demise and smaller pups. CONCLUSIONS: In this rat model, despite biochemical resolution of ischemia-reperfusion injury, subsequent pregnancy resulted in maternal renal insufficiency and significant impairments in fetal growth. This mirrors findings in recent reports in the clinical population, indicating that this model may be a useful tool to further explore the alterations in kidney function after AKI in women.

'I was scared I will end up in another abortion': a mixed-methods study assessing the impact of COVID-19 pandemic and lockdown on the antenatal care of pregnant women in Puducherry, South India.

BACKGROUND: As a mitigation measure for COVID-19 pandemic, lockdown was implemented in India for a period of 2 months (24 March-31 May 2020). Disruption in antenatal care (ANC) provisions during lockdown is expected due to diversion of public health facilities on pandemic. OBJECTIVE: To assess the proportion of pregnant women who had not completed the ideal number of antenatal visits, availability of iron-folic acid (IFA) supplements and challenges in availing health services during the period of lockdown. METHODS: A concurrent mixed-methods study was conducted among pregnant women in Puducherry, India. Information on obstetric characteristics and details regarding antenatal visits were collected through telephonic interviews. In-depth interviews were conducted to understand the perceived challenges in availing health services during the lockdown period. RESULTS: Out of 150 pregnant women, 62 [41.3%; 95% confidence interval (CI) 33.6-49.3] did not complete the ideal number of visits and 61 (40.7%, 95% CI 32.7-49.0) developed health problems. Out of 44 women who received medical care for health problems, 11 (25%) used teleconsultation. Of all the women, 13 (8.7%, 95% CI 4.9-14.0) had not taken the IFA supplements as prescribed by the health provider. Economic hardship, restricted mobility, lack of information about the health system changes and psychological stress due to the fear of COVID were the challenges in accessing care. CONCLUSIONS: Two out of five pregnant women did not complete the ideal number of visits and developed health problems during the lockdown period.

Prevalence of Depressive Symptoms Among Pregnant and Postpartum Women in China During the COVID-19 Pandemic.

OBJECTIVE: According to recent studies, the COVID-19 pandemic has been associated with an increased risk of mental health problems across many subpopulations including pregnant and postnatal women. This study examined the prevalence and correlates of depressive symptoms (depression hereafter) in Chinese pregnant and postpartum women during the COVID-19 pandemic. METHODS: This was a multicenter, cross-sectional study comprising 1309 pregnant and postpartum women across 12 provinces in China during the COVID-19 pandemic. Depression was assessed using the nine-item Patient Health Questionnaire. Univariate analyses and multivariate logistic regression analyses were conducted. RESULTS: The prevalence of depression in pregnant and postpartum women was 27.43% (95% confidence interval [CI] = 25.01%-29.85%). Women who were worried about themselves or their babies being infected with COVID-19 (odds ratio [OR] = 2.562, 95% CI = 1.670-3.929), and those who had delayed regular medical checkups (OR = 2.434, 95% CI = 1.580-3.750) were at higher risk of depression. Compared with those living in central and western parts of China, women living in northern (OR = 0.513, 95% CI = 0.326-0.807) and southeastern parts of China (OR = 0.626, 95% CI = 0.463-0.846) were less likely to have depression. CONCLUSIONS: The COVID-19 pandemic was associated with an increased likelihood of mental health problems among pregnant and postnatal women. Over a quarter of the pregnant and postpartum women in China had depression during the COVID-19 pandemic. Considering the negative health impact of depression, preventive measures, regular mental health screening, and medical checkups are needed with the goal to reduce the risk of depression in this vulnerable population during a pandemic.

[Confinement variables by COVID-19 predictors of anxious and depressive symptoms in pregnant women]. / Variables del confinamiento por COVID-19 predictoras de sintomatología ansiosa y depresiva en mujeres embarazadas.

BACKGROUND AND OBJECTIVES: The appearance of a highly contagious disease forced the confinement of the population in almost all parts of the world, causing an increase in psychological problems, with pregnant women being a particularly vulnerable group to suffer negative consequences. The aim of this research was to check which confinement or psychological stress variables are related to the increase of anxious and depressive symptoms in pregnant women, as a consequence of the pandemic caused by the COVID-19. MATERIALS AND METHODS: The sample was composed of 131 pregnant women who experienced the confinement imposed by the Government of Spain on March 14, 2020. Sociodemographic, obstetric, confinement related and psychological variables were collected. RESULTS: Perceived stress, pregnancy-specific stress, as well as insomnia are predictive variables in most anxious (obsessions and compulsions, anxiety and phobic anxiety) and depressive symptoms related to COVID-19. CONCLUSIONS: It is important to focus future psychological interventions in this population on stress control and sleep monitoring, since these variables influence the increase of anxiety and depression.

The role of pandemic-related pregnancy stress in preference for community birth during the beginning of the COVID-19 pandemic in the United States.

BACKGROUND: The COVID-19 pandemic introduced unparalleled uncertainty into the lives of pregnant women, including concerns about where it is the safest to give birth, while preserving their rights and wishes. Reports on the increased interest in community births (at home or in birth centers) are emerging. The purpose of this project was to quantitatively investigate psychological factors related to this birth preference. METHODS: This study included 3896 pregnant women from the COVID-19 Pregnancy Experiences (COPE) Study who were anticipating a vaginal birth. COPE Study participants were recruited online between April 24 and May 15, 2020, and completed a questionnaire that included preference with respect to place of birth and psychological constructs: fear of childbirth, basic beliefs about birth, pandemic-related preparedness stress, and pandemic-related perinatal infection stress. RESULTS: Women who preferred a community birth, on average, had less childbirth fear, had stronger beliefs that birth is a natural process, were less likely to see birth as a medical process, and were less stressed about being unprepared for birth and being infected with COVID-19. In multivariate models, higher stress about perinatal COVID-19 infection was associated with greater likelihood of preferring a community birth. The effect of perinatal infection stress on preference was stronger when preparedness stress was high. DISCUSSION: Women's birth preferences during the COVID-19 pandemic are associated with psychological processes related to risk perception. Community births are more appealing to women who view being in a hospital as hazardous because of the pandemic. Policies and prenatal care aimed to increase access to safe in-hospital and out-of-hospital birth services should be encouraged.

Prenatal anxiety and obstetric decisions among pregnant women in Wuhan and Chongqing during the COVID-19 outbreak: a cross-sectional study.

OBJECTIVES: To investigate the mental status of pregnant women and to determine their obstetric decisions during the COVID-19 outbreak. DESIGN: Cross-sectional study. SETTING: Two cities in China--Wuhan (epicentre) and Chongqing (a less affected city). POPULATION: A total of 1947 pregnant women. METHODS: We collected demographic, pregnancy and epidemic information from our pregnant subjects, along with their attitudes towards COVID-19 (using a self-constructed five-point scale). The Self-Rating Anxiety Scale (SAS) was used to assess anxiety status. Obstetric decision-making was also evaluated. The differences between cities in all of the above factors were compared and the factors that influenced anxiety levels were identified by multivariable analysis. MAIN OUTCOME MEASURES: Anxiety status and its influencing factors. Obstetric decision-making. RESULTS: Differences were observed between cities in some background characteristics and women's attitudes towards COVID-19 in Wuhan were more extreme. More women in Wuhan felt anxious (24.5 versus 10.4%). Factors that influenced anxiety also included household income, subjective symptom and attitudes. Overall, obstetric decisions also revealed city-based differences; these decisions mainly concerned hospital preference, time of prenatal care or delivery, mode of delivery and infant feeding. CONCLUSIONS: The outbreak aggravated prenatal anxiety and the associated factors could be targets for psychological care. In parallel, key obstetric decision-making changed, emphasising the need for pertinent professional advice. Special support is essential for pregnant mothers during epidemics. TWEETABLE ABSTRACT: The COVID-19 outbreak increased pregnant women's anxiety and affected their decision-making.
