Women perception of SARS-CoV-2 vaccination during pregnancy and subsequent maternal anxiety: a prospective observational study

The impact of COVID-19 pandemic on obstetrics and gynecology hospitalization rate and on reasons for seeking emergency care: a systematic review and meta-analysis

BACKGROUND

During the lockdown due to COVID-19 pandemic, utilization of emergency care units has been reported to be reduced for obstetrical and gynaecological reasons. The aim of this systematic review is to assess if this phenomenon reduced the rate of hospitalizations for any reason and to evaluate the main reasons for seeking care in this subset of the population.

METHODS

The search was conducted using the main electronic databases from January 2020 to May 2021. The studies were identified with the use of a combination of: "emergency department" OR "A&E" OR "emergency service" OR "emergency unit" OR "maternity service" AND "COVID-19" OR "COVID-19 pandemic" OR "SARS-COV-2" and "admission" OR "hospitalization". All the studies that evaluated women going to obstetrics & gynecology emergency department (ED) during the COVID-19 pandemic for any reason were included.

RESULTS

The pooled proportion (PP) of hospitalizations increased from 22.7 to 30.6% during the lockdown periods, in particular from 48.0 to 53.9% for delivery. The PP of pregnant women suffering from hypertensive disorders increased (2.6 vs 1.2%), as well as women having contractions (52 vs 43%) and rupture of membranes (12.0 vs 9.1%). Oppositely, the PP of women having pelvic pain (12.4 vs 14.4%), suspected ectopic pregnancy (1.8 vs 2.0), reduced fetal movements (3.0 vs 3.3%), vaginal bleeding both for obstetrical (11.7 vs 12.8%) and gynecological issues (7.4 vs 9.2%) slightly reduced.

CONCLUSION

During the lockdown, an increase in the proportion of hospitalizations for obstetrical and gynecological reasons has been registered, especially for labor symptoms and hypertensive disorders.

COVID-19 Vaccine Acceptance Among Pregnant, Lactating, and Nonpregnant Women of Reproductive Age in Turkey: A Cross-Sectional Analytical Study

OBJECTIVE

This study aims to identify the rates of coronavirus disease 2019 (COVID-19) vaccine acceptance, the reasons for receiving and not receiving the vaccine, and the associated factors among pregnant, lactating, and nonpregnant women of reproductive age.

METHODS

This cross-sectional and analytical study was conducted online in Turkey, at the end of the fourth wave of the COVID-19 pandemic, between February and May 2022. A total of 658 women (230; 35% pregnant) (187; 28.4% lactating) (241; 36.6% nonpregnant) women of reproductive age participated in the study.

RESULTS

Vaccine acceptance rates were found to be 91.7% in nonpregnant women of reproductive age, 77% in lactating women, and 59% in pregnant women (P < 0.05). The highest rate of vaccine hesitancy was observed in pregnant women (31.3%), and vaccine rejection rate was the highest in lactating women (10.2%). Pregnancy (odds ratio [OR] = 3.98; confidence interval [CI] = 1.13-14.10), and the breastfeeding period (OR = 3.84; CI = 1.15-12.78), increased vaccine hesitancy approximately four times.

CONCLUSIONS

Lack of knowledge about and confidence in the COVID-19 vaccine is still one of the barriers to vaccine acceptance today. Health-care providers (HCPs) should provide effective counseling to pregnant, lactating, and nonpregnant reproductive-aged women based on current information and guidelines.

Covid-19 vaccination during pregnancy: A mixed-methods study of attitudes in a sample of Italian women and the role of health professionals' communication

OBJECTIVES

We examined Italian pregnant women's attitudes about the diphtheria, tetanus, and pertussis (DTP) vaccine, seasonal influenza, and Covid-19 vaccines, healthcare professionals' (HP) communication, reasons and potential predictors for non-adherence.

METHODS

From August 2021 to January 2022, we carried out a cross-sectional study in Italy using an online self-administered questionnaire addressed to women of age and pregnant, designed using LimeSurvey and disseminated through social media. Questions explored vaccination attitude/perceptions, satisfaction, and trust in HPs' information. Thematic analysis of free-text responses was performed using MaxQDA 2022. Statistical analyses were performed using STATA.

RESULTS

1594 responses were obtained. 52% of women hesitated to be vaccinated against Covid-19 while pregnant. Information received by HPs was deemed incomplete by 56% of participants, unclear by 52%, and untrustworthy by 46%; 49% felt unsupported in their decision-making process. This variable was one predictor of vaccine hesitancy together with concern about vaccine safety in the multivariate model. The analysis of open-ended questions revealed a pervasive feeling of dissatisfaction.

CONCLUSION

The perceived lack of adequate communication and support by HPs affected pregnant women's decision-making process on Covid-19 vaccination.

PRACTICE IMPLICATIONS

HPs need to understand and communicate the importance of vaccination during pregnancy, learning to better tailor their messages.

Increasing Vaccine Uptake during Pregnancy by Using Prenatal Education Classes: An Effective Tool for Health Communication and Promotion

Childbirth education classes represent an antenatal tool for supporting pregnant women and couples in increasing knowledge on pregnancy, delivery, breastfeeding, and newborn care. The aim of this study was to investigate the impact of an additional lesson during the prenatal course regarding the advantage of vaccination to mitigation of maternal anxiety. An observational study was designed that included participants in childbirth education classes and compared courses enhanced by the extra lesson on vaccination during pregnancy versus those who did not receive it. Assessment of the impact of prenatal educational on vaccination was measured by using validated questionnaires (State-Trait Anxiety Inventory, STAI; Perceived Stress Scale, PSS; World Health Organization- Five Well-Being Index, WHO-5). A total of 145 pregnant women participated to the investigation by answering to the online survey. Of them, 33 patients (22.8%) belonged to the course without a lesson on vaccine, while 112 (77.2%) participated to online prenatal education that included an additional meeting on the usefulness of getting vaccinated during pregnancy. No statistical differences were found between study groups in terms of demographics and perinatal outcomes. Participants in the enriched course reported lower basal anxiety levels than those without the vaccine lesson (STAI-State, normal score < 40, 30 vs. 19%, p-value 0.041; STAI-State, mild score 40-50, 78 vs. 67%, p-value 0.037). With reference to the prior two weeks, maternal wellbeing level was improved by the added class (score > 13 as measurement of wellbeing: 62% vs. 80%, p-value < 0.05). Moderate perceived stress assessed by PSS was found in those pregnant women without prenatal education on vaccination (64 vs. 50%, p-value 0.042). The introduction of a lesson regarding vaccination during pregnancy in the program of prenatal education courses improved maternal anxiety levels and wellbeing, in addition to reducing perceived stress.

COVID-19 vaccine acceptance among pregnant women: a hospital-based cross-sectional study in Sudan

Introduction

Pregnancy increases the risk of developing a severe illness due to COVID-19 infection. To the best of our knowledge, no previous study has been conducted on COVID-19 vaccine acceptance among pregnant women in Sudan. Hence, this study aimed to determine COVID-19 vaccination acceptance and its predictors among pregnant women.

Methods

A cross-sectional study was conducted among 623 pregnant women attending Gadarif maternity hospital in eastern Sudan through a structured questionnaire. Data were obtained on sociodemographic characteristics, obstetric and health-related characteristics, COVID-19 infection, and vaccination-related information, as well as beliefs about and acceptance of COVID-19 vaccination.

Results

COVID-19 vaccine acceptance among the pregnant women was 2.7%. The vaccine acceptance was higher if their husband's education was secondary school or higher [adjusted odds ratio [AOR] 4.30, 95% confidence interval (CI) 1.11-16.65, p = 0.035] and discussion of COVID-19 vaccine with the pregnant women by a health care professional in the hospital (AOR 5.46, 95% CI 1.94-15.35, p < 0.001). The most common reasons for resistance to the vaccine were concerns about the side effects of the vaccine for the mother and her baby.

Conclusion

Acceptance of the COVID-19 vaccination among the pregnant women was very low. Discussions with pregnant women and their husbands by health care professionals regarding the safety of COVID-19 vaccine for the mother and her baby are highly recommended.

Fetal brain biometry and cortical development after maternal SARS-CoV-2 infection in pregnancy: A prospective case-control study

OBJECTIVES

To assess cerebral growth and the development of fetal cortex using neurosonography in fetuses from pregnancies experiencing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) according to infection timing.

METHODS

Pregnancies with by SARS-CoV-2 during first and second trimesters were prospectively studied and matched with unaffected controls. Enclosed women underwent neurosonography at 30-34 weeks of gestation and corpus callosum (CC) and cerebellar vermis (CV) lengths measured. Further Sylvian fissure (SF), insula. Parieto-occipital fissure (POF), and calcarine sulci fissures (CSF) depths were obtained. The ultrasonographic variables considered were normalized with fetal head size.

RESULTS

One hundred and seventy four consecutive pregnancies experiencing SARS COV 2 infection (81 before 14 weeks and 93 later) and 131 not affected pregnancies were considered. General and pregnancy characteristics were similar between the three groups of women. No significant differences existed in CC and CV lengths across groups. Similarly, insula, SF, POF And CSF depth did not result changed in fetuses of affected mothers.

CONCLUSIONS

SARS-CoV-2 infection does nor resulted associate with differential fetal cortical development or brain growth in mildly symptomatic pregnant women. This information may be useful to reassure infected mothers on the health of their fetuses.

Influence of the COVID-19 pandemic and social media on the behaviour of pregnant and lactating women towards vaccination: a scoping review

BACKGROUND

Pregnant women, foetuses and infants are at risk of infectious disease-related complications. Maternal vaccination is a strategy developed to better protect pregnant women and their offspring against infectious disease-related morbidity and mortality. Vaccines against influenza, pertussis and recently also COVID-19 are widely recommended for pregnant women. Yet, there is still a significant amount of hesitation towards maternal vaccination policies. Furthermore, contradictory messages circulating social media impact vaccine confidence.

OBJECTIVES

This scoping review aims to reveal how COVID-19 and COVID-19 vaccination impacted vaccine confidence in pregnant and lactating women. Additionally, this review studied the role social media plays in creating opinions towards vaccination in these target groups.

ELIGIBILITY CRITERIA

Articles published between 23 November 2018 and 18 July 2022 that are linked to the objectives of this review were included. Reviews, articles not focusing on the target group, abstracts, articles describing outcomes of COVID-19 infection/COVID-19 vaccination were excluded.

SOURCES OF EVIDENCE

The PubMed database was searched to select articles. Search terms used were linked to pregnancy, lactation, vaccination, vaccine hesitancy, COVID-19 and social media.

CHARTING METHODS

Included articles were abstracted and synthesised by one reviewer. Verification was done by a second reviewer. Disagreements were addressed through discussion between reviewers and other researchers.

RESULTS

Pregnant and lactating women are generally less likely to accept a COVID-19 vaccine compared with non-pregnant and non-nursing women. The main reason to refuse maternal vaccination is safety concerns. A positive link was detected between COVID-19 vaccine willingness and acceptance of other vaccines during pregnancy. The internet and social media are identified as important information sources for maternal vaccination.

DISCUSSION AND CONCLUSION

Vaccine hesitancy in pregnant and lactating women remains an important issue, expressing the need for effective interventions to increase vaccine confidence and coverage. The role social media plays in vaccine uptake remains unclear.

Do Anti-SARS-CoV-2 Monoclonal Antibodies Have an Impact on Pregnancy Outcome? A Systematic Review and Meta-Analysis

Monoclonal antibodies (mAbs) have been used as a rescue strategy for pregnant women affected by COVID-19. To explore its impact on maternal-fetal health, we included all observational studies reporting maternal, fetal, delivery and neonatal outcomes in women who underwent mAbs infusion for COVID-19. Primary outcome was the percentage of preterm delivery. We used meta-analyses of proportions to combine data for maternal, fetal, delivery and neonatal outcome of women treated with mAbs for COVID-19 and reported pooled proportions and their 95% confidence intervals (CIs) for categorical variables or mean difference (MD) with their 95% confidence intervals for continuous variables. Preterm birth was observed in 22.8% of cases (95% CI 12.9-34.3). Fetal distress was reported in 4.2% (95% CI 1.6-8.2). Gestational hypertension and pre-eclampsia were observed in 3.0% (95% CI 0.8-6.8) and 3.4% (95% CI 0.8-7.5) of cases, respectively. Fetal growth restriction was observed in 3.2% of fetuses (95% CI 0.8-7.0). Secondary prophylaxis with mAbs is currently considered the best treatment option for people with mild to moderate COVID-19 disease. More attention should be paid to infants born from mothers who were treated with mAbs, for the risk of immunosuppression.

The prevalence of mental ill-health in women during pregnancy and after childbirth during the Covid-19 pandemic: a systematic review and Meta-analysis

BACKGROUND

This systematic review aims to explore the prevalence of the impact of the COVID-19, MERS, and SARS pandemics on the mental health of pregnant women.

METHODS

All COVID-19, SARS and MERS studies that evaluated the mental health of pregnant women with/without gynaecological conditions that were reported in English between December 2000 - July 2021 were included. The search criteria were developed based upon the research question using PubMed, Science Direct, Ovid PsycINFO and EMBASE databases. A wide search criterion was used to ensure the inclusion of all pregnant women with existing gynaecological conditions. The Newcastle-Ottawa-Scale was used to assess the risk of bias for all included studies. Random effects model with restricted maximum-likelihood estimation method was applied for the meta-analysis and I-square statistic was used to evaluate heterogeneity across studies. The pooled prevalence rates of symptoms of anxiety, depression, PTSD, stress, and sleep disorders with 95% confidence interval (CI) were computed.

RESULTS

This systematic review identified 217 studies which included 638,889 pregnant women or women who had just given birth. There were no studies reporting the mental health impact due to MERS and SARS. Results showed that women who were pregnant or had just given birth displayed various symptoms of poor mental health including those relating to depression (24.9%), anxiety (32.8%), stress (29.44%), Post Traumatic Stress Disorder (PTSD) (27.93%), and sleep disorders (24.38%) during the COVID-19 pandemic.

DISCUSSION

It is important to note that studies included in this review used a range of outcome measures which does not allow for direct comparisons between findings. Most studies reported self-reported measure of symptoms without clinical diagnoses so conclusions can be made for symptom prevalence rather than of mental illness. The importance of managing mental health during pregnancy and after-delivery improves the quality of life and wellbeing of mothers hence developing an evidence-based approached as part of pandemic preparedness would improve mental health during challenging times.

OTHER

The work presented in this manuscript was not funded by any specific grants. A study protocol was developed and published in PROSPERO (CRD42021235356) to explore several key objectives.

COVID-19 Vaccination and Related Determinants of Hesitancy among Pregnant Women: A Systematic Review and Meta-Analysis

Mass vaccination against COVID-19 is necessary to control the pandemic. COVID-19 vaccines are now recommended during pregnancy to prevent the disease. A systematic review of the literature in the electronic databases PubMed and EMBASE was performed and we aimed to investigate the attitude of documents towards COVID-19 vaccination and the prognostic factors of vaccination hesitation. A meta-analysis was also conducted to estimate the overall percentage of pregnant women who were willing to be vaccinated or had been vaccinated against COVID-19. A total of 18 studies were included in the review and meta-analysis. The acceptance rate of vaccination against COVID-19 among pregnant women ranged from 17.6% to 84.5%. The pooled proportion of acceptance of vaccination against COVID-19 in pregnant women was 0.53 (95% CI: 0.44-0.61). Predictors of acceptance of COVID-19 vaccination were older age, White race, occupational status, higher level of education, comorbidities, third trimester of pregnancy, influenza vaccination, knowledge about COVID-19, and confidence that vaccines for COVID-19 are safe and effective. The prevalence of COVID-19 vaccination in pregnant women is low. Targeted information campaigns are needed to increase vaccine education in this population.

Attitudes toward COVID-19 vaccination of pregnant and lactating women in Hungary

OBJECTIVES

This study has three purposes. First, we explore the percentage of the population that is vaccinated and the factors that contribute to whether or not an individual takes up COVID-19 vaccination. Second, we also look at how pregnant and lactating women (PLW) take up vaccination. Third, we reveal what the public think about PLW receiving vaccines.

METHODS

Questionnaire data collection was carried out online using the quota method among Hungarians aged 18-65 with Internet access. The survey was carried out between 29th November and 11th December 2021. A total of 1,000 participants completed the questionnaire.

RESULTS

A total of 66.4% of the respondents aged 18-65 received vaccination. There were significant differences across sociodemographic variables in vaccination: men and individuals with more education, better perceived financial status, and personal experience with COVID-19 were more likely to be vaccinated. PLW were less likely to be vaccinated, partly due to their fear of vaccines' side-effects. More than one third of the participants do not agree with PLW having COVID-19 vaccination. In general, attitudes toward vaccination of PLW differed significantly by social group. Men and individuals with tertiary education and better financial situation, who knew somebody who had died of COVID-19 infection, and who had been vaccinated were more likely to accept vaccination for both pregnant women and lactating mothers.

CONCLUSIONS

Acceptance of receiving COVID-19 vaccination depends on social status; thus, targeted campaigns are required. In addition, PLW are afraid of vaccines' side effects, so they should be provided information, just as there is a need to increase public information on this topic.

COVID-19 in Pregnancy: Knowledge about the Vaccine and the Effect of the Virus. Reliability and Results of the MAMA-19 Questionnaire

BACKGROUND

Fear or mistrust of the vaccine and concern for the well-being of their unborn infants are the main reasons for COVID-19 vaccine hesitancy in pregnant women. The aim of this work was to validate a questionnaire on knowledge about COVID-19 vaccination during pregnancy and to examine the sources of information in a group of new mothers, as well as their effectiveness and intelligibility.

METHODS

A literature review was carried out to develop a questionnaire of forty-five questions, divided into six sections, called MAMA-19. The assessment of agreement and the interrater reliability was carried out using Cronbach's analysis and Cohen's kappa statistic. Data obtained from the questionnaire were analysed using descriptive and univariate statistics.

RESULTS

The total alpha values in the two sections about knowledge of vaccination during pregnancy and about the effects of disease and possible post-COVID-19 consequences for the unvaccinated showed sufficient consistency, at 0.860 and 0.725, respectively. Non-vaccinated women thought that receiving the COVID-19 vaccine during pregnancy can lead to malformations in the newborn (60% vs. 40%, p = 0.002) and to an increased risk of foetal growth restriction (61.9% vs. 38.1%, p < 0.001). The percentage of vaccinated women was significantly higher than non-vaccinated when more than one professional was consulted and consistent information was received from them (74.2% vs. 25.8%, p = 0.008).

CONCLUSION

The MAMA-19 questionnaire shows results in line with the literature and valid in the two main sections. It is quick to use for measuring communication effectiveness by healthcare professionals and institutions in the context of the COVID-19 vaccination campaign in the pregnant population. The results evidence that a physician's recommendation to get vaccinated is the most important factor in maternal decision making, regardless of geographic, social or educational context.

Factors associated with willingness to take COVID-19 vaccine among pregnant women at Gondar town, Northwest Ethiopia: A multicenter institution-based cross-sectional study

BACKGROUND

Coronavirus disease has spread worldwide since late 2019. Vaccination is critical in controlling this pandemic. However, vaccine acceptance among pregnant women is not well-studied. Therefore, this study aimed to assess the COVID-19 vaccine acceptance and associated factors among pregnant women attending antenatal care clinics in Gondar town, Northwest Ethiopia.

METHODS

An institution-based cross-sectional study was conducted among pregnant women attending antenatal care clinics at Gondar town, Northwest Ethiopia, 2021. About 510 study subjects were selected using a systematic random sampling technique from August 25 to September 10/2021. Data collection was done by using an interviewer-administered, structured questionnaire. Epi-info 7.2 was used to enter data and then exported to SPSS version 25 software for analysis. Bivariable and multivariable binary logistic regression models were used to identify factors associated with the outcome variable. Variables with a p-value < 0.2 in the bivariable analysis were entered into the multivariable analysis to control for possible confounders. Statistical significance is determined using an adjusted odds ratio and 95% confidence interval (CI) at a p-value of < 0.05.

RESULTS

Of 510 participants, 211 (41.4%) were willing to take COVID-19 vaccines. Maternal age ≥ 35 years (AOR: 5.678, 95% CI: 1.775-18.166), having contact history with COVID-19 diagnosed people (AOR: 7.724, 95% CI: 2.183, 27.329), having a pre-existing chronic disease (AOR: 3.131, 95% CI: 1.700-5.766), good knowledge about COVID-19 vaccine (AOR: 2.391, 95% CI: 1.144, 4.998) and good attitude towards COVID-19 vaccine (AOR: 2.128, 95% CI: 1.348) were significantly associated with the outcome variable.

CONCLUSIONS

The willingness to take COVID-19 vaccine among pregnant mothers was low. Age, contact history with COVID-19 diagnosed people, chronic disease, knowledge, and attitude towards COVID-19 vaccine were factors associated with COVID-19 vaccine willingness. To enhance the COVID-19 vaccine acceptance, the government with different stakeholders should strengthen public education about the importance of getting COVID-19 vaccine.

Trends in Caesarean Section Rate According to Robson Group Classification among Pregnant Women with SARS-CoV-2 Infection: A Single-Center Large Cohort Study in Italy

BACKGROUND

Since there is no available data on temporal trends of caesarean section (CS) rates in pregnant women with COVID-19 through the pandemic, we aimed to analyze the trends in caesarean section rate in a large cohort of pregnant women with COVID-19, according to the Robson Ten Group Classification System of deliveries.

METHODS

We prospectively enrolled pregnant women with a diagnosis of COVID-19 who delivered in our center between March 2020 and November 2021. Deliveries were classified, according to the Robson group classification, and according to three time periods: (1) deliveries from March 2020 to December 2020; (2) deliveries from January 2021 to April 2021; (3) deliveries from May 2021 to November 2021. We compared pregnancy characteristics and incidence of caesarean section, according to the Robson category in the total population, and according to the three time periods.

RESULTS

We included 457 patients matching the inclusion criteria in our analysis. We found that overall CS rate significantly decreased over time from period 1 to period 3 (152/222, 68.5% vs. 81/134, 60.4% vs. 58/101, 57.4%, χ2 = 4.261, p = 0.039). CS rate significantly decreased over time in Robson category 1 (48/80, 60% vs. 27/47,57.4% vs. 8/24, 33.3%, χ2 = 4.097, p = 0.043) and Robson category 3 (13/42, 31% vs. 6/33, 18.2% vs. 2/22, 9.1%, χ2 = 4.335, p = 0.037). We also found that the incidence of induction of labor significantly increased over time (8/222, 3.6% vs. 12/134, 9% vs. 11/101, 10.9%, χ2 = 7.245, p = 0.027).

CONCLUSION

Our data provide an overview of the temporal changes in the management and obstetric outcome of COVID-19 pregnant women through the pandemic, confirming that standards of obstetrical assistance for pregnancies complicated by SARS-CoV-2 infection improved over time.

COVID-19 vaccination hesitancy and willingness among pregnant women in Italy

Background

Pregnant women, especially those with comorbidities, compared to those non-pregnant, have higher risk of developing a severe form of COVID-19. However, COVID-19 vaccine uptake is very low among them.

Methods

An anonymous questionnaire was administered to randomly selected women 18 years of age that were currently pregnant or had just given birth between September 2021 and May 2022 in the geographic area of Naples. Vaccine hesitancy was assessed using the vaccine hesitancy scale (VHS).

Results

A total of 385 women participated. Women who had not been infected by SARS-CoV-2 and who needed information about vaccination against COVID-19 had a higher perceived risk of being infected with SARS-CoV-2. More than half (54.3%) of the women were very afraid of the potential side effects of the COVID-19 vaccination on the fetus. There was higher concern of the side effects of the vaccine on the fetus among those who did not have a graduate degree, those with high-risk pregnancy, those who had not been infected by SARS-CoV-2, those who were more concerned that they could be infected by SARS-CoV-2, those who did not know that this vaccination was recommended for them, and those trusting mass media/internet/social networks for information. Only 21.3% were vaccinated when pregnant, mostly women with a university degree, those who had been infected by SARS-CoV-2 before pregnancy, those who did not need information, and those who acquired information about the vaccination from gynecologists. Almost three-quarters (71.9%) were willing to receive the vaccination and those more likely were those with a university degree, those who have had at least one relative/cohabitant partner/friend who had been infected by SARS-CoV-2, those who were more concerned that they could be infected by SARS-CoV-2, and those who were not extremely concerned of the side effects of the vaccine on the fetus. A total of 86.4% were highly hesitant. Highly hesitant were respondents who did not get a graduate degree, those less concerned that they could be infected by SARS-CoV-2, and those trusting mass media/internet/social networks for information.

Conclusion

Public health efforts and education campaigns for pregnant women are needed for changing their perception patterns and for supporting gynecologists in promoting the uptake of this vaccination.

COVID-19 vaccine acceptance among pregnant women worldwide: A systematic review and meta-analysis

Background

The COVID-19 pandemic has led to the death of many people worldwide. The World Health Organization (WHO) has declared vaccine resistance as one of the greatest health threats in the world even before the COVID-19 epidemic. The aim of this study was to evaluate the acceptance of COVID-19 vaccine in pregnant women.

Method

We performed this systematic review and meta-analysis in accordance with the PRISMA guidelines. We applied the standard search strategy to the PubMed/Medline, Web of Science (ISI), Scopus, Science Direct, Cochrane Library, EMBASE, and EBSCO databases, and the Google Scholar search engine. Heterogeneity between studies was relatively high and therefore meta-analyses were performed based on random effects model with 95% CI using STATA version 16.

Results

In 16 articles with a sample size of 19219 pregnant women, the acceptance of COVID-19 vaccine was estimated 53.46% (95%CI: 47.64%-59.24%). Subgroup analysis was performed based on continent (p = 0.796), data collection method (p = 0.450) and meta-regression based on the month of the study (P<0.001), and only meta-regression was significant based on the month of the study. The effect of some variables such as graviad (OR = 1.02 [95%CI: 0.90–1.16]), maternal age was (OR = 1.02 [95%CI: 0.93–1.11]) and history of influenza vaccination (OR = 0.87 [95%CI: 0.71–1.06]) on COVID-19 vaccine acceptance was evaluated, which was not significant.

Conclusion

The prevalence of COVID-19 vaccine acceptance in pregnant women was 53.46%, which was much lower than the general COVID-19 vaccination. Therefore, necessary interventions should be taken to increase the acceptance of the vaccine, address safety concerns and educate about it.

Acceptance towards COVID-19 vaccination in Latin America and the Caribbean: A systematic review and meta-analysis

INTRODUCTION

Vaccination represents an important strategy to mitigate COVID-19 related morbidity and mortality by protecting against severe forms of the disease and reducing hospitalization and death rates. In this sense, the objective of this study is to estimate the prevalence of Vaccination Intention (VI) against COVID-19 in Latin America and Caribbean (LAC).

METHODS

We conducted a systematic review with a comprehensive search strategy for the following databases: PubMed, Scopus and Web of Science. A random-effect model meta-analysis was carried out using observational studies assessing the intention to vaccines against COVID-19 in LAC countries. The Clopper-Pearson method was used to estimate 95% Confidence Intervals. The quality assessment was developed using the Newcastle-Ottawa Scale adapted for cross-sectional studies. A subgroup analysis by study location and a sensitivity analysis were developed.

RESULTS

Nineteen cross-sectional studies were included. Five meta-analyzes were performed according to the target population of the included studies. The VI in the general population of LAC was 78.0% (95%CI: 74.0%-82.0%). The VI for non-pregnant women was 78.0% (95%CI: 58.0%-99.0%), for elderly population was 63.0% (95%CI: 59.0%-69.0%), for pregnant women was 69.0% (95%CI: 61.0%-76.0%) and for health-personnel was 83.0% (95% CI: 71.0%-96.0%). The sensitivity analysis for general population meta-analysis that included only low risk of bias studies showed a 77.0% VI (95%CI: 73.0%-82.0%) and for non-pregnant women, 85.0% VI (95%CI: 79.0%-90.0%).

CONCLUSION

Despite the high prevalence of VI in general population found in our study, VI prevalence from elderly people and pregnant women are lower than other population groups and overall population.

Systematic review and critical evaluation of quality of clinical practice guidelines on the management of SARS-CoV-2 infection in pregnancy

OBJECTIVE

To systematically identify and critically assess the quality of clinical practice guidelines for the management of SARS-CoV-2 infection in pregnancy.

DATA SOURCES

Medline, Scopus, and ISI Web of Science databases were searched until February 15, 2022.

STUDY ELIGIBILITY CRITERIA

Inclusion criteria were clinical practice guidelines on the management of SARS-CoV-2 infection in pregnancy. The risk of bias and quality assessments of the included clinical practice guidelines were performed using the Appraisal of Guidelines for REsearch and Evaluation II tool, which is considered the gold standard for quality assessment of clinical practice guidelines. To define a clinical practice guideline as of good quality, we adopted the cutoff score proposed by Amer et al: if the overall clinical practice guideline score was >60%, it was recommended.

METHODS

The following clinical points related to the management of pregnant women with SARS-CoV-2 infection were addressed: criteria for maternal hospitalization, recommendations for follow-up fetal growth scan, specific recommendations against invasive procedures, management of labor, timing of delivery, postpartum care, and vaccination strategy.

RESULTS

A total of 28 clinical practice guidelines were included. All recommended hospitalization only for severe disease; 46.1% (6/13) suggested a fetal growth scan after SARS-CoV-2 infection, whereas 23.1% (3/13) did not support this practice. Thromboprophylaxis with low-molecular-weight heparin was recommended in symptomatic women by 77.1% (7/9) of the clinical practice guidelines. None of the guidelines recommended administering corticosteroids only for the presence of SARS-CoV-2 infection in preterm gestation, unless specific obstetrical indication exists. Elective induction of labor from 39 weeks of gestation was suggested by 18.1% (2/11) of the clinical practice guidelines included in the present review, whereas 45.4% (5/11) did not recommend elective induction unless other obstetrical indications coexisted. There were 27% (3/11) of clinical practice guidelines that suggested shortening of the second stage of labor, and active pushing was supported by 18.1% (2/11). There was general agreement among the clinical practice guidelines in not recommending cesarean delivery only for the presence of maternal infection and in recommending vaccine boosters at least 6 months after the primary series of vaccination. The Appraisal of Guidelines for REsearch and Evaluation II standardized domain scores for the first overall assessment of clinical practice guidelines had a mean of 50% (standard deviation±21.82%), and 9 clinical practice guidelines scored >60%.

CONCLUSION

A significant heterogeneity was found in some of the main aspects of the management of SARS-CoV-2 infection in pregnancy, as reported by the published clinical practice guidelines.

Absence of SARS-CoV-2 Spike glycoprotein expression in placentas from individuals after mRNA SARS-CoV-2 vaccination

Current public health initiatives to contain the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) global pandemic focus on expanding vaccination efforts to include vulnerable populations such as pregnant people. Vaccines using messenger ribonucleic acid (mRNA) technology rely on translation by immune cells, primarily at the injection site. Hesitancy remains among the general population regarding the safety of mRNA vaccines during gestation, and it remains unknown whether the SARS-CoV-2 Spike protein (the product of mRNA vaccines available) accumulates in the placenta after vaccination. Objective: To determine whether Spike protein translation and accumulation occurs in placental tissue in the context of recent mRNA SARC-CoV-2 vaccination during pregnancy. We identified 48 patients receiving one or two doses of mRNA SARS-CoV-2 vaccine during gestation and used immunohistochemistry against SARS-CoV-2 Spike protein in formalin-fixed, paraffin-embedded placental tissue. One placenta, positive for SARS-CoV-2 RNA by in situ hybridization (ISH) was used as positive control. Seven term placentas collected prior to the emergence of SARS-CoV-2 served as negative controls. Eighty one percent of patients in the study group underwent third-trimester delivery; remaining had a first-trimester spontaneous abortion or elective second-trimester termination. Patients received two (52%) or one (48%) vaccine doses during pregnancy, with a median interval between latest dose and delivery of 13 days (range 2-79 days). Most (63%) cases had their latest dose within 15 days prior to delivery. All the placentas in the study and negative control groups were negative for SARS-CoV-2 immunohistochemistry. Six study cases with short vaccine-delivery intervals (2-7 days) were subjected to SARS-CoV-2 ISH and were negative. Our findings suggest that mRNA vaccines do not reach significant concentrations in the placenta given the absence of definitive SARS-CoV-2 Spike protein accumulation in placental tissue. This observation provides evidence supporting the safety of mRNA vaccines to the placental-fetal unit.

COVID-19 vaccine hesitancy among pregnant women: a systematic review and meta-analysis

OBJECTIVE

The aim of this study was to perform a systematic review and meta-analysis to estimate the vaccines' acceptance level and to find the factors influencing pregnant women's vaccination decisions, with the goal of assisting in the development of interventions and promoting more research in this area.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

MEDLINE, Embase, CINAHL and PubMed.

ELIGIBILITY CRITERIA

Studies providing any kind of quantitative assessment of overall COVID-19 vaccination acceptance among pregnant women in any country or region across the globe.

DATA EXTRACTION AND SYNTHESIS

The pooled prevalence of COVID-19 vaccine acceptance among pregnant women was calculated using the random-effects model. Subgroup (sensitivity) analysis was performed to determine the overall COVID-19 vaccine acceptance level to understand the sources of substantial heterogeneity.

RESULTS

Out of the 375 studies identified, 17 studies from four continents assessing 25 147 participants (pregnant women) were included in this study. Among the participants, only 49% (95% CI 42% to 56%, p<0.001) had COVID-19 vaccine acceptance. High-income countries (47%; 95% CI 38% to 55%, p<0.001), participants with fewer than 12 years of education (38%; 95% CI 19% to 58%, p<0.001) and multiparous women (48%; 95% CI 31% to 66%, p<0.001) had lower COVID-19 vaccine acceptance. Overall heterogeneity was high (I² ≥98%), and publication bias was present (p<0.001). A very weak positive correlation between COVID-19 knowledge and COVID-19 vaccine acceptance was observed (r=0.164; 95% CI -0.946 to 0.972; p=0.8359).

CONCLUSION

Overall, COVID-19 vaccine acceptance among pregnant women was low across the studies and considerably low among some specific subgroups of participants. These research findings have implications for the development of effective interventions that could increase the COVID-19 vaccine acceptance level among pregnant women to attain herd immunity.

Covid-19 vaccination in pregnancy

Pregnancy is an independent risk factor for severe covid-19. Vaccination is the best way to reduce the risk for SARS-CoV-2 infection and limit its morbidity and mortality. The current recommendations from the World Health Organization, Centers for Disease Control and Prevention, and professional organizations are for pregnant, postpartum, and lactating women to receive covid-19 vaccination. Pregnancy specific considerations involve potential effects of vaccination on fetal development, placental transfer of antibodies, and safety of maternal vaccination. Although pregnancy was an exclusion criterion in initial clinical trials of covid-19 vaccines, observational data have been rapidly accumulating and thus far confirm that the benefits of vaccination outweigh the potential risks. This review examines the evidence supporting the effectiveness, immunogenicity, placental transfer, side effects, and perinatal outcomes of maternal covid-19 vaccination. Additionally, it describes factors associated with vaccine hesitancy in pregnancy. Overall, studies monitoring people who have received covid-19 vaccines during pregnancy have not identified any pregnancy specific safety concerns. Additional information on non-mRNA vaccines, vaccination early in pregnancy, and longer term outcomes in infants are needed. To collect this information, vaccination during pregnancy must be prioritized in vaccine research.

COVID-19 vaccination hesitancy in pregnant and breastfeeding women and strategies to increase vaccination compliance: a systematic review and meta-analysis

INTRODUCTION

Pregnant and breastfeeding women are at an increased risk of severe illness from COVID-19. Despite this, low vaccination coverages are reported in this population sub-group.

AREAS COVERED

The purpose of this study is to estimate the proportion of pregnant and breastfeeding women expressing hesitation to the COVID-19 vaccine worldwide. Forty-six studies were included in the meta-analysis and systematic review, selected from scientific articles available in the MEDLINE/PubMed, Google Scholar, and Scopus databases between January 1, 2020 and February 6, 2022. The vaccine hesitation rate among pregnant and breastfeeding women was 48.4% (95%CI= 43.4-53.4%). In a sub analysis by study period, it was 40.0% (95%CI=31.6-46.6%) considering surveys administered in 2020, 58.0% (95%CI=48.9-66.9%) considering surveys administered in the first semester of 2021, and 38.1% (95%CI=25.9-51.2%) considering surveys administered in the second semester of 2021. The main reasons for vaccine hesitation were lack of information about vaccination, opinion that the vaccine is unsafe, and fear of adverse events.

EXPERT OPINION

Available evidence in the literature has shown that fighting vaccine resistance is harsh and too slow as a process, considering the rapidity and unpredictability of a pandemic. Health education should be provided in order to improve the willingness of the community, especially for those with lower levels of education.

Uptake of COVID-19 Vaccines among Pregnant Women: A Systematic Review and Meta-Analysis

Mass vaccination against COVID-19 is essential to control the pandemic. COVID-19 vaccines are now recommended during pregnancy to prevent adverse outcomes. With this review, we aimed to evaluate the evidence in the literature regarding the uptake of COVID-19 vaccinations among pregnant women. A comprehensive search was performed in PubMed, Medline, Scopus, ProQuest, Web of Science, CINAHL, and medRxiv from inception to 23 March 2022. We performed a meta-analysis to estimate the overall proportion of pregnant women vaccinated against COVID-19. We found 11 studies including 703,004 pregnant women. The overall proportion of pregnant women vaccinated against COVID-19 was 27.5% (95% CI: 18.8–37.0%). Predictors of COVID-19 vaccination uptake were older age, ethnicity, race, trust in COVID-19 vaccines, and fear of COVID-19 during pregnancy. Mistrust in the government, diagnosis of COVID-19 during pregnancy, and fears about the safety and side effects of COVID-19 vaccines were reasons for declining vaccination. The global COVID-19 vaccination prevalence in pregnant women is low. A large gap exists in the literature on the factors influencing the decision of pregnant women to be vaccinated against COVID-19. Targeted information campaigns are essential to increase vaccine literacy among pregnant women.

Intention to Receive COVID-19 Vaccine during Pregnancy: A Systematic Review and Meta-analysis

OBJECTIVE

This meta-analysis aimed to assess the level of intent to receive coronavirus disease 2019 (COVID-19) vaccination and demographical factors influencing vaccine uptake among pregnant individuals.

STUDY DESIGN

PubMed, Scopus, and archive/pre-print servers were searched up to May 22nd, 2021. Cross sectional surveys reporting the percentage of the pregnant individuals intending to get a COVID-19 vaccine were considered eligible for meta-analysis. This review was registered with PROSPERO (CRD42021254484). The primary outcome was to estimate the prevalence of COVID-19 vaccination intent among pregnant population. The secondary outcome was to evaluate the factors influencing the intention for vaccination.

RESULTS

Twelve studies sourcing data of 16,926 individuals who were identified as pregnant were eligible. The estimated intention for the receipt of COVID-19 vaccine among women who were pregnant was 47% (95% CI: 38-57%), with the lowest prevalence in Africa 19% (95% CI: 17-21%) and the highest in Oceania 48.0% (95% CI: 44.0-51.0%). Uptake of other vaccines (influenza and/or TdaP) during pregnancy was associated with higher rate of intent to receive the COVID-19 vaccine (OR = 3.03; 95% CI: 1.37-6.73; p = 0.006).

CONCLUSION

The intent to receive COVID-19 vaccine is relatively low among women who are pregnant and substantially varies based on the country of residence. In our meta-analysis, intent of women who were pregnant to receive the COVID-19 vaccine was significantly associated with the history of receiving influenza or TdaP vaccine during pregnancy. Given that in every country only a minority of gravidae have received the COVID-19 vaccine, despite known risks of maternal morbidity and mortality with no evidence of risks of vaccination, it highlights the importance of revised approaches at shared decision making and focused public health messaging by national and international advisories.

KEY POINTS

· The estimated global intention for COVID-19 vaccination among pregnant women was 47%.. · The lowest intention was in Africa and the highest in Oceania.. · These findings highlight the importance of public health messaging by by different agencies..

Approach of Pregnant Women from Poland and the Ukraine to COVID-19 Vaccination—The Role of Medical Consultation

There are many arguments for the safety and efficacy of COVID-19 vaccines in pregnancy. The aim of this study is to describe the level of vaccination acceptance, to find the factors that most influence the decision to vaccinate, and to describe the scale of changes in vaccination acceptance influenced by medical information on the safety, efficacy, and benefits of vaccination among pregnant women. A total of 300 patients completed the questionnaire, including 150 in Poland and 150 in the Ukraine. The level of vaccination acceptance was assessed before and after medical consultation. There were 53 (35.3%) patients with the intention to get vaccinated in Poland and 25 (16.7%) in the Ukraine. After consultation with a physician, this increased to 109 (72.6%) in Poland and 69 (46%) in the Ukraine. The main factors influencing the acceptance of vaccinations were the fear of harming the foetus (OR-0.119, CI-0.039–0.324 p < 0.001), complications in pregnancy (OR-0.073 CI-0.023–0.197 p < 0.001), and limitations in the vaccination programme (OR-0.026 CI-0.001–0.207 p < 0.001). Medical information about the safety, effectiveness and benefits of vaccinations among pregnant women, provided during a medical visit, may increase the acceptance of vaccinations by 105.6%, as among Polish patients, and by 176%, as among pregnant women from the Ukraine.

The negative impact of most relevant infections on fertility and assisted reproduction technology

Infections may act with variable impact on the physiopathology of the reproductive organs, determining infertility or reducing the outcomes of assisted reproduction technology. The aim of this narrative review is to describe the existing evidence regarding the pathogens with a supposed or recognized role in reproductive medicine. Viral hepatitis, as well as HIV, can reduce sperm quality. Syphilis carries a risk of erectile dysfunction and increased endometrial thickness. Chlamydia is the main cause of pelvic inflammatory disease. In relation to Mycoplasma and Ureaplasma spp., only few species seem to show a correlation with infertility and poor in-vitro fertilization outcomes. There is evidence of a role for bacterial vaginosis in early pregnancy loss. HPV infection in males seems to determine infertility. Herpesviruses are more a risk for fetuses than for fertility itself. Zika virus is responsible for altered early embryo development and waiting to conceive is recommended in suspected or confirmed cases. The impact of SARS-CoV-2 is yet to be elucidated. Rubella and toxoplasmosis can provoke important congenital defects and therefore screening is mandatory before conception; a vaccine for Rubella is recommended. Further and well-designed studies are still needed to better elucidate the role of some infectious agents, to improve fertility and its treatments.

Challenges for the practice of evidence-based medicine during COVID-19 pandemic (practice of evidence-based medicine in the new normal)

The forces which had kept the evidence-based medicine (EBM) movement alive and ongoing have altered significantly during this coronavirus disease (COVID)-19 pandemic. There has been discrepancy in the demand and availability of scientific evidence. Deaths of thousands of people including physicians and other health-care workers (while offering COVID-19 care) across the globe have shaken the confidence of the physicians towards the practice of EBM. Journals started publishing in a hurry, incomplete and at times misleading scientific articles, about COVID-19, leaving the physicians in a dilemma about the evidence. The practitioner of EBM has had to turn helplessly to non-documentary evidences to treat COVID-19 patients. Apart from the evidence becoming hyperdynamic and volatile along with a reduction in its quality, the environment got polluted by political interference. In a nutshell, the COVID-19 pandemic has affected the practice of EBM and its acceptance in multiple ways.

Worldwide beliefs among pregnant women on SARS-CoV-2 vaccine: a systematic review

BACKGROUND

SARS-CoV-2 vaccine has been recommended to pregnant women, but survey studies showed contrasting findings worldwide in relation to the willingness to accept vaccination during pregnancy.

OBJECTIVE

To evaluate the evidence from the literature regarding the acceptance rate of the SARS-CoV-2 vaccine in pregnant and breastfeeding women.

STUDY DESIGN

We performed a systematic review on the main databases (MEDLINE (PubMed), Scopus, ISI Web of Science) searching for all the peer-reviewed survey studies analyzing the eventual acceptance rate of the SARS-CoV-2 vaccine among pregnant and breastfeeding women. To combine data meta-analyses of proportions and pooled proportions with their 95% confidence intervals (CI) were calculated.

RESULTS

15 studies including 25,839 women were included in the analysis. The proportion of women actually willing to be vaccinated during pregnancy is 49.1% (95% CI, 42.3-56.0), and the proportion of breastfeeding women is 61.6% (95% CI, 50.0-75.0).

CONCLUSION

The cumulative SARS-CoV-2 vaccine acceptance rate among pregnant women appears still low. Vaccinal campaign are urgently needed to drive more confidence into the vaccine to help reducing the spread of the infection and the possible consequences during pregnancy.

The Impact of Maternal Anxiety on Early Child Development During the COVID-19 Pandemic

Background: Maternal prenatal anxiety is among important public health issues as it may affect child development. However, there are not enough studies to examine the impact of a mother's anxiety on the child's early development, especially up to 1 year. Objective: The present prospective cohort study aimed to examine whether maternal trait anxiety, perceived social support, and COVID-19 related fear impacted speech-language, sensory-motor, and socio-emotional development in 12 months old Serbian infants during the COVID-19 pandemic. Methods: This follow-up study included 142 pregnant women (Time 1) and their children at 12 months (Time 2). Antenatal maternal anxiety and children's development were examined. Maternal anxiety was assessed using the State-Trait Anxiety Inventory (STAI). Child speech-language, sensory-motor, and socio-emotional development were assessed using the developmental scale in the form of an online questionnaire that examined the early psychophysiological child development. Information on socioeconomic factors, child and maternal demographics, clinical factors, and perceived fear of COVID-19 viral infection were collected. Multivariable General Linear Model analysis was conducted, adjusted for demographic, clinical, and coronavirus prenatal experiences, maternal prenatal anxiety levels, perceived social support, speech-language, motor skills, and cognitive and socio-emotional development at the infants' age of 12 months. Results: The study revealed the influence of the COVID-19 pandemic on maternal trait anxiety. The association between selected independent factors and infants' development was found in a demographically unified sample except for employment and the number of children. There was a correlation between all observed developmental functions. Univariate General Linear model statistical analysis indicated that linear models with selected independent factors and covariates could account for 30.9% (Cognition) up to 40.6% (Speech-language) of variability in developmental functions. It turned out that two-way and three-way interactions had a dominant role on models, and STAI-T Level and COVID-19 related fear were present in all interaction terms. Conclusion: Our findings reveal important determinants of child developmental outcomes and underline the impact of maternal anxiety on early child development. These findings lay the groundwork for the following interdisciplinary research on pregnancy and child development to facilitate and achieve positive developmental outcomes and maternal mental health.

Effects of COVID-19 on maternal anxiety and depressive disease: a literature review

The coronavirus SARS-CoV-2 (COVID-19) infection is a public health emergency of international concern. Pandemics pose a challenge to psychological resilience and can have an adverse impact on mental health. The impact of the ensuing social isolation and loneliness imposed by quarantine along with the worries about the risks of the infection and its economic fallout would appear likely to affect the mental health of the population. It has been reported that women are more likely to experience anxiety and depression symptoms during COVID-19 than men. COVID-19 pandemic had a profound impact on the level of anxiety and depression of pregnant women according to their basal level and pregnancy characteristics. Antenatal mental disorders may be a risk factor for maternal mental health problems such as an increased likelihood of postnatal depression and adverse obstetric and developmental outcomes. Effective coping strategies are associated with better psychological wellbeing during the COVID-19 pandemic, including reduced anxiety and depression. The increased risk of mental disorders due to COVID-19 requires policies to be developed to address prenatal and postpartum care to promote maternal-child wellbeing outcomes.

Crohn's and Colitis Canada's 2021 Impact of COVID-19 and Inflammatory Bowel Disease in Canada: Children and Expectant Mothers With Inflammatory Bowel Disease

Coronavirus disease 2019 (COVID-19) in children with inflammatory bowel disease (IBD) typically results in a mild infection, similar to those without IBD. Children and adolescents have less severe manifestations of COVID-19 compared to older people, whether or not they have IBD. However, some IBD medications (in particular, corticosteroids) are associated with more severe COVID-19. During the first year of the global pandemic, more IBD care was provided with online technology, necessitated by efforts to reduce hospital and clinic visits. Additionally, non-endoscopic monitoring of inflammation has been required due to the cancellation of non-urgent procedures, resulting in longer endoscopy wait-times. In contrast, pregnant people (with and without IBD) who contract COVID-19 are at increased risk of severe manifestations, death and preterm delivery, making them a priority for severe acute respiratory syndrome coronavirus 2 protective measures and vaccination. Few studies have examined effect of COVID-19 on IBD-related disease activity in pregnant people with IBD. The pandemic has significantly affected the mental health and sense of well-being of children and their families, as well as pregnant people with IBD. These groups were much more likely to experience anxiety and depression compared with prior to the pandemic, even while concern has mostly abated regarding the effect of IBD medications and COVID-19 severity. Unfortunately, the availability of mental health care providers who specialize in people with IBD has not kept pace with the increasing demand.

The association of maternal SARS-CoV-2 vaccination-to-delivery interval and the levels of maternal and cord blood antibodies

OBJECTIVE

To evaluate the correlation of maternal and cord blood levels of SARS-CoV-2 antibodies in pregnant women immunized against COVID-19.

METHODS

A prospective cohort study was performed of pregnant women who delivered at a single university affiliated tertiary medical center. Women who received the COVID-19 vaccine (BNT162b2 Pfizer©) were approached. The correlation between levels of maternal sera and umbilical cord SARS-CoV-2 specific IgG was assessed.

RESULTS

Overall, 58 women were included; of them, 19 had received a single dose and 39 received two doses of the COVID-19 vaccine. Positive levels of umbilical cord IgG were found in 13/19 (68.4%) and 38/39 (97.4%) women after the administration of a single dose and two doses of the vaccine, respectively. The levels of SARS-CoV-2 IgG antibodies in the maternal sera of vaccinated women were positively correlated to their respective concentrations in cord blood sera (ρ = 0.857; R² linear = 0.719; P < 0.001). Thirteen days after vaccination, the ratio of maternal-to-umbilical cord anti Spike IgG antibodies was approximately 1, indicating relatively similar levels in maternal and cord sera.

CONCLUSION

After the SARS-CoV-2 vaccine, levels of maternal and cord blood antibodies were positively correlated, especially when tested after 13 days following administration of the first dose of the vaccine.

Placental histopathology after SARS-CoV-2 infection in pregnancy: a systematic review and meta-analysis

OBJECTIVE

This study aimed to report the spectrum of placental pathology findings in pregnancies complicated by SARS-CoV-2 infection.

DATA SOURCES

MEDLINE, Embase, Google Scholar, and the Web of Science databases were searched up to August 11, 2021.

STUDY ELIGIBILITY CRITERIA

Histopathologic anomalies included maternal vascular malperfusion, fetal vascular malperfusion, acute inflammatory pathology, chronic inflammatory pathology, increased perivillous fibrin, and intervillous thrombosis. Moreover, subanalyses of symptomatic women only and high-risk pregnancies were performed.

METHODS

Histopathologic analysis of the placenta included gross examination, histopathology on hematoxylin and eosin, immunohistochemistry, fluorescence in situ hybridization, quantitative reverse transcription-polymerase chain reaction on placental tissue, and transmission electron microscope. Random-effect meta-analyses were used to analyze the data.

RESULTS

A total of 56 studies (1008 pregnancies) were included. Maternal vascular malperfusion was reported in 30.7% of placentas (95% confidence interval, 20.3-42.1), whereas fetal vascular malperfusion was observed in 27.08 % of cases (95% confidence interval, 19.2-35.6). Acute and chronic inflammatory pathologies were reported in 22.68% (95% confidence interval, 16.9-29.0) and 25.65% (95% confidence interval, 18.4-33.6) of cases, respectively. Increased perivillous fibrin was observed in 32.7% (95% confidence interval, 24.1-42.0) of placentas undergoing histopathologic analysis, whereas intervillous thrombosis was observed in 14.6% of cases (95% confidence interval, 9.7-20.2). Other placental findings, including a basal plate with attached myometrial fibers, microscopic accretism, villous edema, increased circulating nucleated red blood cells, or membranes with hemorrhage, were reported in 37.5% of cases (95% confidence interval, 28.0-47.5), whereas only 17.5% of cases (95% confidence interval, 10.9-25.2) did not present any abnormal histologic findings. The subanalyses according to maternal symptoms owing to SARS-CoV-2 infection or the presence of a high-risk pregnancy showed a similar distribution of the different histopathologic anomalies to that reported in the main analysis. Moreover, the risk of placental histopathologic anomalies was higher when considering only case-control studies comparing women with SARS-CoV-2 infection with healthy controls.

CONCLUSION

In pregnant women with SARS-CoV-2 infection, a significant proportion of placentas showed histopathologic findings, suggesting placental hypoperfusion and inflammation. Future multicenter prospective blinded studies are needed to correlate these placental lesions with pregnancy outcomes.

The Approach of Pregnant Women to Vaccination Based on a COVID-19 Systematic Review

Background and Objectives: Pregnant women are more likely to develop a more severe course of COVID-19 than their non-pregnant peers. There are many arguments for the safety and efficacy of COVID-19 vaccines in pregnant women. The aim of this study is to conduct a systematic review concerning the approach of pregnant women towards vaccination against COVID-19, with particular regard to determinants of vaccination acceptance. Materials and Methods: Articles were reviewed in which the aim was to evaluate—via a survey or questionnaire—the acceptance and decision to undergo vaccination against COVID-19. The articles were subjected to review according to recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA). Results: In various studies, the percentage of pregnant women accepting the COVID-19 vaccine was between 29.7% and 77.4%. The strongest factors co-existing with the acceptance of the COVID-19 vaccination in pregnancy were trust in the importance and effectiveness of the vaccine, explicit communication about the safety of COVID-19 vaccines for pregnant women, acceptance of other vaccinations such as those for influenza, belief in the importance of vaccines/mass vaccination in one’s own country, anxiety about COVID-19, trust in public health agencies/health science, as well as compliance to mask guidelines. The remaining factors were older age, higher education, and socioeconomic status. Conclusions: This review allowed us to show that geographic factors (Asian, South American countries) and pandemic factors (different threats and risks from infection) significantly influence the acceptance of vaccines. The most significant factors affecting acceptance are those related to public awareness of the risk of infection, vaccine safety, and the way in which reliable information about the need and safety of vaccines is provided. Professional and reliable patient information by obstetricians and qualified medical personnel would significantly increase the level of confidence in vaccination against COVID-19.

Obstetric A&E unit admission and hospitalization for obstetrical management during COVID-19 pandemic in a third-level hospital of southern Italy

Background

The COronaVIrus Disease 2019 (COVID-19) has spread in Italy since February 2020, inducing the government to call for lockdown of any activity, apart primary needs, during the months March–May 2020. During the lockdown, a reduction of admissions and hospitalizations for ischemic diseases was noticed. Purpose of this study was to observe if there has been the same reduction trend in Accident & Emergency (A&E) unit admissions also for obstetric-gynecological conditions.

Methods

Medical records and electronic clinical databases were searched for all patients who were admitted to the obstetric A&E department or hospitalized at the Gynecology and Obstetrics Unit of University hospital of Naples Federico II, during the quarter March–May in the years 2019 and 2020. The mean ± standard deviation (SD) of monthly admission to the obstetric A&E department and hospitalization of the year 2020 was compared with that of the year 2019, using the unpaired T test with α error set to 0.05 and 95% confidence intervals (95% CI).

Results

Admissions were 1483 in the year 2020 and 1786 in 2019. Of total, 1225 (37.5%) women were hospitalized: 583 in the year 2020, 642 in 2019. Mean ± SD of patients monthly admitted to our obstetric A&E department was 494 ± 33.7 in the year 2020, and 595.3 ± 30.9 in 2019, with a mean difference of − 101.3 (95% CI − 103.5 to − 99.1; p < 0.0001). Mean ± SD of patients monthly hospitalized to our department was 194 ± 19.1 in the year 2020, 213.7 ± 4.7 in 2019, with a mean difference of − 19.7 (95% CI − 23.8 to − 15.6; p < 0.0001).

Conclusion

A significant decrease in the mean of monthly admissions and hospitalizations during the COVID-19 pandemic when compared to the previous year was found also for obstetric–gynecological conditions. Further studies are necessary to assess COVID-19 impact and to take the most appropriate countermeasures.

The subanalyses according to maternal symptoms owing to SARS-CoV-2 infection or the presence of a high-risk pregnancy showed a similar distribution of the different histopathologic anomalies to that reported in the main analysis. Moreover, the risk of placental histopathologic anomalies was higher when considering only case-control studies comparing women with SARS-CoV-2 infection with healthy controls.

CONCLUSION

In pregnant women with SARS-CoV-2 infection, a significant proportion of placentas showed histopathologic findings, suggesting placental hypoperfusion and inflammation. Future multicenter prospective blinded studies are needed to correlate these placental lesions with pregnancy outcomes.

Predictors of pregnant women's intention to vaccinate against coronavirus disease 2019: A facility-based cross-sectional study in southwest Ethiopia

OBJECTIVE

Ethiopia is planning to vaccinate 20% of its population against the coronavirus disease 2019 pandemic by the end of 2021-however, there is no single piece of evidence regarding pregnant women's intention to be vaccinated against coronavirus disease 2019; hence, the objective of this study was to investigate predicting factors of intention to be vaccinated against coronavirus disease 2019 among pregnant women in Bench-Sheko Zone, southwest Ethiopia.

METHODS

Facility-based cross-sectional study was undertaken from 1 February to 1 March 2021 in southwest Ethiopia. The study was carried out among pregnant women who came for antenatal care service in the selected public health facilities. Interviewer-administered structured tool was used to collect the data. Data were entered into EpiData (version 3.1) and then analyzed using SPSS (version 20).

RESULTS

The study revealed that only 31.3% (95% confidence interval: 26.7-35.2) of the participants had an intention to be vaccinated against coronavirus disease 2019 when the vaccine will be made available in Ethiopia. Participants' intention to be vaccinated against coronavirus disease 2019 was significantly associated with attaining secondary school and above (adjusted odds ratio = 4.24, 95% confidence interval: 2.23-9.32), residing in urban areas (adjusted odds ratio = 2.57, 95% confidence interval: 1.22-5.40), being compliant with coronavirus disease 2019 guidelines (adjusted odds ratio = 5.86, 95% confidence interval: 3.40-10.09), and having good perception toward coronavirus disease 2019 vaccine (adjusted odds ratio = 3.04, 95% confidence interval: 1.64-5.62).

CONCLUSION

Above all, in this study, pregnant women's intention to vaccinate against coronavirus disease 2019 was very low when compared with previous studies. Hence, before commencing the coronavirus disease 2019 vaccination program in Ethiopia, it is essential to launch a widespread public health education campaign that could improve people's perception of the vaccine. Besides, the upcoming public health intervention programs better put special emphasis on community members with lower educational attainment backgrounds and rural residents.

What may happen if you are pregnant during Covid-19 lockdown? A retrospective study about peripartum outcomes

BACKGROUND

One of the provisions implemented to contain the spread of Covid-19 infections in Italy was the lockdown. Effects of the lockdown on childbirth outcomes and on the well-being of both the mother and the child have not yet been defined. An inadequate diet during pregnancy and a reduced physical activity can predispose women to become overweight or obese and trigger the development of various complications and maternal-fetal adverse outcomes.

METHODS

This is a retrospective study including all consecutive patients who delivered at University Hospital Maggiore della Carità in Novara, Italy, in April-May 2017 (group 1, n=294), a period prior to the pandemic, and during the same months in 2020 (group 2, n=256) during and immediately after lockdown. Clinical data were extracted from The Report "Childbirth Assistance Certificate (CedAP) - Birth Event Analysis".

RESULTS

Demographic characteristics were similar between the two study groups, except for a decreased number of married couples in group 2 (p-value 0.018) and an increased percentage of patients with clinical checkups at Family Planning facilities in 2020 (p-value 0.04). The number of hospitalizations during pregnancy was 26 (8.9%) vs 10 (3.9%) with a significative reduction during 2020 (p-value 0.004). Regarding obstetric outcomes, we observed a significant increase in induction of labour in 2020 (23.9% vs 35.9%; p-value 0. 002), a reduction of amniorrhexis (11.3% vs 5.5% p-value 0.015), a reduction of supine positions with an increase of vertical and all fours positions in 2020 (49.3% vs 61.9% and 9.5% vs 12.4% respectively, p 0.023), and a reduction of left occipito-anterior presented part (63.2% vs 55.4%) in favor of right occipito-anterior (34.7% vs 41.2%, p-value 0.019).

CONCLUSIONS

There were no significant differences either for antepartum or intrapartum complications. Long-term studies are needed to evaluate psychological, behavioral, and epigenetic effects of maternal physical inactivity on obstetric outcomes.
