Differential impact of COVID-19 in pregnant women from high-income countries and low- to middle-income countries: A systematic review and meta-analysis

Adverse perinatal outcomes of unvaccinated pregnant women with respiratory symptoms during the COVID-19 pandemic: Evidence from a Brazilian multicenter study

OBJECTIVE

The current study aimed to describe risk factors for adverse perinatal outcomes (APOs) among pregnant women nonvaccinated for COVID-19 who had respiratory symptoms.

METHODS

A nested case-control study was performed within the REBRACO (in Portuguese, the Brazilian Network of COVID-19 During Pregnancy) initiative. Women were recruited during pregnancy in 15 maternity hospitals in Brazil from February 1, 2020, to February 28, 2021, while seeking medical care for respiratory symptoms, and were followed up until childbirth regardless of confirmation of COVID-19. For this analysis, women were divided into two groups: (1) those with APOs, defined as the occurrence of fetal or neonatal death, preterm delivery, 5-min Apgar score <7, neonatal respiratory distress, neonatal mechanical ventilation, admission to the neonatal intensive care unit, small-for-gestational-age newborn, or any neonatal morbidity; and (2) those without APOs.

RESULTS

The total number of women included in this analysis was 481, with 210 having APOs (43.7%). The characteristics independently associated with APOs were a composite outcome of severe acute respiratory syndrome, maternal admission at the intensive care unit, or maternal death (relative risk [RR], 3.30 [95% confidence interval (CI), 1.38-7.89]), living in the North and Northeastern regions of Brazil (RR, 3.09 [95% CI, 1.13-8.41]), and pre-eclampsia (RR, 2.77 [95% CI, 1.19-6.43]).

CONCLUSION

Severe maternal illness was strongly associated with APO regardless of COVID-19 confirmation. It is essential to provide sufficient and timely health care for women who have respiratory symptoms compatible with COVID-19.

Sociodemographic Factors Associated With Established and Novel Antenatal Vaccination Uptake in a Cohort of Pregnant Women in Uganda

INTRODUCTION

Vaccination is a key strategy to safeguard the health of pregnant women and newborns. Although vaccine acceptance is often higher in low- and middle-income countries, the COVID-19 pandemic has highlighted increasing vaccine hesitancy. Vaccine hesitancy, specifically in pregnant women, must be understood to increase uptake. We used data from a Ugandan pregnancy registry study to examine sociodemographic factors linked to uptake of vaccines (tetanus toxoid and later COVID-19) in pregnancy.

METHODS

Pregnant women were recruited in Kampala, Uganda, as part of the PREPARE (Prevention of invasive Group B Streptococcus disease in young infants: a pathway for the evaluation & licensure of an investigational maternal GBS vaccine) study from September 1, 2020 until February 24, 2022. Demographic, socioeconomic and obstetric data were collected alongside COVID-19 and tetanus vaccination.

RESULTS

One thousand five hundred sixty-eight participants were included: 151 (10%) were unvaccinated, 11 (1%) received COVID-19 vaccine only, 1230 (78%) received a tetanus vaccine only and 176 (11%) received both. Lower vaccination rates were seen in participants attending fewer than 4 antenatal care episodes (P < 0.001), and those with higher parity (P = 0.036). Higher vaccination rates were seen with a managerial or professional occupation or higher maternal education level, but paternal occupation was not significantly associated with maternal vaccination. Parish vaccination rates varied from 0% to 100%, with 49 (29%) of parishes showing a vaccination rate <90%.

CONCLUSIONS

This study highlights antenatal care as a key route for health promotion, and the stark difference in uptake between new and established antenatal vaccines. Further qualitative studies should investigate effective interventions to establish the safety and benefit of newer maternal vaccines across all demographic groups.

The impact of COVID-19 mitigation measures on neonatal health outcomes in sub-Saharan Africa: A systematic review and meta-analysis

OBJECTIVES

To assess the relationship between COVID-19 mitigation measures and stillbirth, low birth weight (LBW), and preterm birth (PTB) in sub-Saharan Africa.

STUDY DESIGN

Systematic review/meta-analysis.

METHODS

We searched six databases for literature indexed from January 2020 to December 2022 for studies examining COVID-19 policies and neonatal outcomes in sub-Saharan Africa. These studies were assessed for their risk of bias and described via narrative synthesis. Meta-analysis with random effects was performed to generate risk ratios (RRs) that were stratified by study scope to explore heterogeneity.

RESULTS

Our search identified 515 unique studies, sixteen of which were included. Most studies were multi-/single-center examinations (n = 7) and national/regional investigations (n = 6). The stillbirth RR suggested a marginal increase during mitigation measures (RR: 1.13; 95 % CI: 0.97, 1.31); however, among national/regional studies, there was no increase (RR: 0.96; 95 % CI: 0.82, 1.14). Similarly, the LBW RR suggested an increase during mitigation measures (RR: 1.18; 95 % CI: 0.90, 1.56), but the RR among national/regional investigations indicated no increase (RR: 0.97; 95 % CI: 0.91, 1.04). For PTB, the RR indicated no increase during mitigation measures (RR: 1.00; 95 % CI: 0.94, 1.07); there were no differences between multi-/single-center examinations and national/regional investigations.

CONCLUSIONS

Our results suggest that outcome risk did not change after mitigation measures were imposed when focusing on national/regional investigations and provide insights for both African health officials and researchers.

Comparative analysis of COVID-19 pneumonia in pregnant versus matched non-pregnant women: radiologic, laboratory, and clinical perspectives

This study aimed to assess the severity and outcomes of COVID-19 in pregnant women, focusing on laboratory and radiological discrepancies between pregnant women and matched nonpregnant women. In this retrospective cross-sectional analysis, we matched 107 nonpregnant women with 66 pregnant women in terms of age, comorbidities, and the interval between symptom onset and hospital admission. Demographic, clinical, laboratory, and radiological data were collected, and chest CT scans were evaluated using a severity scale ranging from 0 to 5. Logistic regression and adjusted Cox regression models were used to assess the impact of various factors on pregnancy status and mortality rates. Differences in several laboratory parameters, including the neutrophil-to-lymphocyte ratio, liver aminotransferases, alkaline phosphatase, urea, triglycerides, cholesterol, HbA1c, ferritin, coagulation profiles, and blood gases, were detected. Radiologic exams revealed that nonpregnant women had sharper opacities, whereas pregnant women presented with hazy opacities and signs of crypt-organizing pneumonia. A notable difference was also observed in the pulmonary artery diameter. The mortality rate among pregnant women was 4.62%, which was comparable to the 5.61% reported in nonpregnant patients. Compared with nonpregnant patients, pregnancy did not significantly affect the severity or mortality of COVID-19. Our study revealed discernible differences in specific laboratory and imaging markers between pregnant and nonpregnant COVID-19 patients.

No impact of COVID-19 at delivery on maternal mortality or infant adverse birth outcomes in Botswana during the Omicron era

SARS-CoV-2 infection during pregnancy was associated with maternal mortality and adverse birth outcomes in the pre-Omicron era, including a stillbirth rate of 5.6% in Botswana. We re-evaluated these outcomes in the Tsepamo Study during the Omicron era. We assessed maternal mortality and adverse birth outcomes for all singleton pregnancies from mid-November 2021 (the start of the Omicron era) to mid-August 2022 at nine Tsepamo sites, among individuals with documented SARS-CoV-2 screening PCR or antigen tests and known HIV status. Of 9,705 women routinely screened for SARS-CoV-2 infection at delivery (64% of deliveries at these sites), 373 (3.8%) tested positive. Women with HIV were as likely to test positive for SARS-CoV-2 (77/1833, 4.2%) as women without HIV (293/6981, 4.2%) (p = 1.0). There were 5 recorded maternal deaths (0.03%), one occurring in a woman with a positive SARS-CoV-2 test result. In contrast, maternal mortality was 3.7% and 0.1% in those with and without SARS-CoV-2, respectively, during the pre-Omicron era. In the Omicron era, there were no differences among infants exposed or unexposed to SARS-CoV-2 in overall adverse birth outcomes (28.1% vs 29.6%; aRR 1.0, 95%CI 0.8-1.1), severe adverse birth outcomes (11.9 vs 10.6%; aRR 1.1, 95%CI 0.8-1.5), preterm delivery (15.1% vs 14.9%; aRR 1.0, 95%CI 0.8-1.3), or stillbirth (1.9% vs 2.3%; aRR 0.8, 95%CI 0.4-1.7). Adverse outcomes among those exposed to both HIV and SARS-CoV-2 were similar to those exposed to HIV alone (31.2% vs. 33.1%; aRR 0.9, 95%CI 0.6-1.3; p = 0.5). Maternal mortality was far lower in Botswana during the Omicron era than in the pre-Omicron era, and adverse birth outcomes were no longer significantly impacted by exposure to SARS-CoV-2 either overall or with HIV co-exposure. Increased population immunity to SARS-CoV-2, less stress on the hospital systems in the Omicron era, and possible differences in viral pathogenicity may combine to explain these findings.

In Situ Analyses of Placental Inflammatory Response to SARS-CoV-2 Infection in Cases of Mother-Fetus Vertical Transmission

It has been shown that vertical transmission of the SARS-CoV-2 strain is relatively rare, and there is still limited information on the specific impact of maternal SARS-CoV-2 infection on vertical transmission. The current study focuses on a transcriptomics analysis aimed at examining differences in gene expression between placentas from mother-newborn pairs affected by COVID-19 and those from unaffected controls. Additionally, it investigates the in situ expression of molecules involved in placental inflammation. The Papa Giovanni XXIII Hospital in Bergamo, Italy, has recorded three instances of intrauterine transmission of SARS-CoV-2. The first two cases occurred early in the pandemic and involved pregnant women in their third trimester who were diagnosed with SARS-CoV-2. The third case involved an asymptomatic woman in her second trimester with a twin pregnancy, who unfortunately delivered two stillborn fetuses due to the premature rupture of membranes. Transcriptomic analysis revealed significant differences in gene expression between the placentae of COVID-19-affected mother/newborn pairs and two matched controls. The infected and control placentae were matched for gestational age. According to the Benjamani-Hochberg method, 305 genes met the criterion of an adjusted p-value of less than 0.05, and 219 genes met the criterion of less than 0.01. Up-regulated genes involved in cell signaling (e.g., CCL20, C3, MARCO) and immune response (e.g., LILRA3, CXCL10, CD48, CD86, IL1RN, IL-18R1) suggest their potential role in the inflammatory response to SARS-CoV-2. RNAscope® technology, coupled with image analysis, was utilized to quantify the surface area covered by SARS-CoV-2, ACE2, IL-1β, IL-6, IL-8, IL-10, and TNF-α on both the maternal and fetal sides of the placenta. A non-statistically significant gradient for SARS-CoV-2 was observed, with a higher surface coverage on the fetal side (2.42 ± 3.71%) compared to the maternal side (0.74 ± 1.19%) of the placenta. Although not statistically significant, the surface area covered by ACE2 mRNA was higher on the maternal side (0.02 ± 0.04%) compared to the fetal side (0.01 ± 0.01%) of the placenta. IL-6 and IL-8 were more prevalent on the fetal side (0.03 ± 0.04% and 0.06 ± 0.08%, respectively) compared to the maternal side (0.02 ± 0.01% and 0.02 ± 0.02%, respectively). The mean surface areas of IL-1β and IL-10 were found to be equal on both the fetal (0.04 ± 0.04% and 0.01 ± 0.01%, respectively) and maternal sides of the placenta (0.04 ± 0.05% and 0.01 ± 0.01%, respectively). The mean surface area of TNF-α was found to be equal on both the fetal and maternal sides of the placenta (0.02 ± 0.02% and 0.02 ± 0.02%, respectively). On the maternal side, ACE-2 and all examined interleukins, but not TNF-α, exhibited an inverse mRNA amount compared to SARS-CoV-2. On the fetal side, ACE-2, IL-6 and IL-8 were inversely correlated with SARS-CoV-2 (r = -0.3, r = -0.1 and r = -0.4, respectively), while IL-1β and IL-10 showed positive correlations (r = 0.9, p = 0.005 and r = 0.5, respectively). TNF-α exhibited a positive correlation with SARS-CoV-2 on both maternal (r = 0.4) and fetal sides (r = 0.9) of the placenta. Further research is needed to evaluate the correlation between cell signaling and immune response genes in the placenta and the vertical transmission of SARS-CoV-2. Nonetheless, the current study extends our comprehension of the molecular and immunological factors involved in SARS-CoV-2 placental infection underlying maternal-fetal transmission.

Maternal inflammatory and microbial drivers of low birthweight in low- and middle-income countries

BACKGROUND

Low birthweight (LBW) is when an infant is born too soon or too small, and it affects one in seven infants in low- and middle-income countries. LBW has a significant impact on short-term morbidity and mortality, and it impairs long-term health and human capital. Antenatal microbial and inflammatory exposure may contribute to LBW.

METHODS

Ovid-Medline, Embase and Cochrane databases were searched for English-language articles evaluating inflammatory, microbial or infective causes of LBW, small-for-gestational age, intra-uterine growth restriction or prematurity. Inclusion criteria were human studies including published data; conference abstracts and grey literature were excluded. A narrative synthesis of the literature was conducted.

RESULTS

Local infections may drive the underlying causes of LBW: for example, vaginitis and placental infection are associated with a greater risk of prematurity. Distal infection and inflammatory pathways are also associated with LBW, with an association between periodontitis and preterm delivery and environmental enteric dysfunction and reduced intra-uterine growth. Systemic maternal infections such as malaria and HIV are associated with LBW, even when infants are exposed to HIV but not infected. This latter association may be driven by chronic inflammation, co-infections and socio-economic confounders. Antimicrobial prophylaxis against other bacteria in pregnancy has shown minimal impact in most trials, though positive effects on birthweight have been found in some settings with a high infectious disease burden.

CONCLUSION

Maternal inflammatory and infective processes underlie LBW, and provide treatable pathways for interventions. However, an improved understanding of the mechanisms and pathways underlying LBW is needed, given the impact of LBW on life-course.

Impacts of COVID-19 on mothers' and newborns' health outcomes in regional Canada: A cross-sectional analysis

Background

COVID-19 infection and pandemic-related stressors (e.g., socioeconomic challenges, isolation) resulted in significant concerns for the health of mothers and their newborns during the perinatal period. Therefore, the primary objective of this study was to compare the health outcomes of pregnant mothers and their newborns one year prior to and one year into the pandemic period in Alberta, Canada. Secondary objectives included investigating: 1) predictors of admission to neonatal intensive care units (NICU) and to compare NICU-admitted newborn health outcomes between the two time periods; 2) hospital utilization between the two time periods; and 3) the health outcomes of mothers and their newborns following infection with COVID-19.

Methods

This analytical cross-sectional study used a large administrative dataset (n = 32,107) obtained from provincial regional hospitals and homebirths in Alberta, Canada, from April 15, 2019, to April 14, 2021. Descriptive statistics characterized the samples. Chi-squares and two-sample t-tests statistically compared samples. Multivariable logistic regression identified predictor variables.

Results

General characteristics, pregnancy and labor complications, and infant outcomes were similar for the two time periods. Preterm birth and low birthweight predicted NICU admission. During the pandemic, prevalence of hospital visits and rehospitalization after discharge decreased for all infants and hospital visits after discharge decreased for NICU-admitted neonates. The odds of hospital revisits and rehospitalization after discharge were higher among newborns with COVID-19 at birth.

Conclusions

Most of the findings are contextualized on pandemic-related stressors (rather than COVID-19 infection) and are briefly compared with other countries. Hospitals in Alberta appeared to adapt well to COVID-19 since health conditions were comparable between the two time periods and COVID-19 infection among mothers or newborns resulted in few observable impacts. Further investigation is required to determine causal reasons for changes in hospital utilization during the pandemic and greater birthweight among pandemic-born infants.

"It's what we perceive as different": an interpretative phenomenological analysis of Nigerian women's characterization of their health during the COVID-19 pandemic

BACKGROUND

Health has historically been adversely affected by social, economic, and political pandemics. In parallel with the spread of diseases, so do the risks of comorbidity and death associated with their consequences. As a result of the current pandemic, shifting resources and services in resource-poor settings without adequate preparation has intensified negative consequences, which global service interruptions have exacerbated. Pregnant women are especially vulnerable during infectious disease outbreaks, and the current pandemic has significantly impacted them.

METHODS

This study used an interpretive phenomenological analysis study with a feminist lens to investigate how women obtained healthcare in Ebonyi, Ogun, and Sokoto states Nigeria during the COVID-19 pandemic. We specifically investigated whether the epidemic influenced women's decisions to seek or avoid healthcare and whether their experiences differed from those outside of it.

RESULTS

We identified three superordinate themes: (1) the adoption of new personal health behaviour in response to the pandemic; (2) the pandemic as a temporal equalizer for marginalized individuals; (3) the impacts of the COVID-19 pandemic on maternal health care. In Nigeria, pregnant women were affected in a variety of ways by the COVID-19 epidemic. Women, particularly those socially identified as disabled, had to cross norms of disadvantage and discrimination to seek healthcare because of the pandemic's impact on prescribed healthcare practices, the healthcare system, and the everyday landscapes defined by norms of disadvantage and discrimination.

CONCLUSION

It is clear from the current pandemic that stakeholders must begin to strategize and develop plans to limit the effects of future pandemics on maternal healthcare, particularly for low-income women.

Impact of the Early COVID-19 Pandemic on the Quality of Obstetric Care in a Tertiary Care Center in Karachi, Pakistan

Objective This study aimed to assess the indirect impact of the COVID-19 pandemic on obstetric quality measures. Materials and methods This cross-sectional study was conducted at a private-sector tertiary care hospital in Karachi, Pakistan. Data were collected for specific antenatal, intrapartum, and postpartum care indicators during the initial six months of the COVID-19 phase (March to August 2020) and compared with baseline measures from the preceding six months before the COVID-19 phase (September 2019 to February 2020) using frequencies and percentages. Results During COVID-19, there was a 10% reduction (pre-COVID: 1041 and during COVID: 946) in outpatient obstetric volumes and a 65% increase (pre-COVID: 240 and during COVID: 396) in clinic cancellations, indicating a decreased influx of antenatal patients. Teleclinics served 8.3% (1429/18279) of the total obstetric patients during this period. Marginal decreases were observed in spontaneous vaginal deliveries 1358 (44%) vs 1049 (42.4%) and labor induction rates 818 (26.6%) vs 606 (24.2%). Additionally, there was a slight increase in instrumental deliveries, 121 (3.9%) vs 114 (4.6%) during the COVID phase. However, these changes were not statistically significant. Similarly, no substantial impact was observed on elective and emergency C-sections. Notably, there were more cases of primary postpartum hemorrhage (PPH) during the COVID-19 phase 36 (1.17%) vs 46 (1.86%), and these changes were statistically significant (p= 0.035). Similar trends were observed for eclampsia (p =0.05) and preeclampsia cases (p-value 0.074). However, other maternal morbidity indicators and intrauterine fetal deaths remained relatively unchanged. NICU admissions increased significantly (p=0.001), while early neonatal deaths remained unaffected. Patient satisfaction rates remained steady for inpatients and improved for outpatients during COVID-19. Conclusion The COVID-19 pandemic primarily affected antenatal volumes, neonatal admissions, and maternal morbidity indicators such as PPH, preeclampsia, and eclampsia. Despite the challenges, patient satisfaction and quality care standards were maintained during COVID-19 through new strategies and revised patient care processes.

Clinical Characteristics, Outcomes, and Risk Factors for Mortality in Pregnant/Puerperal Women with COVID-19 Admitted to ICU in Turkey: A Multicenter, Retrospective Study from a Middle-Income Country

BACKGROUND

Coronaviruses have been the cause of 3 major outbreaks during the last 2 decades. Information on coronavirus diseases in pregnant women is limited, and even less is known about seriously ill pregnant women. Data are also lacking regarding the real burden of coronavirus disease 2019 (COVID-19) infection in pregnant women from low/middle-income countries. The aim of this study was to determine the characteristics and clinical course of COVID-19 in pregnant/puerperal women admitted to ICUs in Turkey.

METHODS

This was a national, multicenter, retrospective study. The study population comprised all SARS-CoV-2-infected pregnant/puerperal women admitted to participating ICUs between 1 March 2020 and 1 January 2022. Data regarding demographics, comorbidities, illness severity, therapies, extrapulmonary organ injuries, non-COVID-19 infections, and maternal and fetal/neonatal outcomes were recorded. LASSO logistic regression and multiple logistic regression analyses were used to identify predictive variables in terms of ICU mortality.

RESULTS

A total of 597 patients (341 pregnant women, 255 puerperal women) from 59 ICUs in 44 hospitals were included and of these patients, 87.1% were unvaccinated. The primary reason for ICU admission was acute hypoxemic respiratory failure in 522 (87.4%), acute hypoxemic respiratory failure plus shock in 14 (2.3%), ischemic cerebrovascular accident (CVA) in 5 (0.8%), preeclampsia/eclampsia/HELLP syndrome in 6 (1.0%), and post-caesarean follow-up in 36 (6.0%). Nonsurvivors were sicker than survivors upon ICU admission, with higher APACHE II (p < 0.001) and SOFA scores (p < 0.001). A total of 181 (30.3%) women died and 280 (46.6%) had received invasive mechanical ventilation (IMV). Myocardial injury, the highest SOFA score during ICU stay, LDH levels on admission, the highest levels of AST during ICU stay, average daily dose of corticosteroids, IMV, prophylactic dose anticoagulation (compared with therapeutic dose anticoagulation), PaO2/FiO2 ratio <100, pulmonary embolism, and shock were identified as predictors of mortality. Rates of premature birth (46.4%), cesarean section (53.7%), fetal distress (15.3%), stillbirth (6.5%), and low birth weight (19.4%) were high. Rates of neonatal death (8%) and respiratory distress syndrome (21%) were also high among live-born infants.

CONCLUSIONS

Severe/critical COVID-19 infection during the pregnancy/puerperal period was associated with high maternal mortality and fetal/neonatal complication rates in Turkey.

Impact of the COVID-19 pandemic on access to and delivery of maternal and child healthcare services in low-and middle-income countries: a systematic review of the literature

Background

The COVID-19 pandemic has had a multifaceted impact on maternal and child services and adversely influenced pregnancy outcomes. This systematic review aims to determine the impact of the COVID-19 pandemic on access to and delivery of maternal and child healthcare services in low- and middle-income countries.

Methods

The review was reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A primary search of electronic databases was performed using a combination of search terms related to the following areas of interest: "impact' AND 'COVID-19' AND 'maternal and child health services' AND 'low- and middle-income countries. A narrative synthesis approach was used to analyse and integrate the results.

Results

Overall, 45 unique studies conducted across 28 low- and middle-income countries met the inclusion criteria for the review. The findings suggest the number of family planning visits, antenatal and postnatal care visits, consultations for sick children, paediatric emergency visits and child immunisation levels decreased compared to the pre-pandemic levels in the majority of included studies. An analytical framework including four main categories was developed based on the concepts that emerged from included studies: the anxiety of not knowing (1), overwhelmed healthcare systems (2), challenges perceived by healthcare professionals (3) and difficulties perceived by service users (4).

Conclusion

The COVID-19 pandemic disrupted family planning services, antenatal and postnatal care coverage, and emergency and routine child services. Generalised conclusions are tentative due to the heterogeneity and inconsistent quality of the included studies. Future research is recommended to define the pandemic's impact on women and children worldwide and prepare healthcare systems for future resurgences of COVID-19 and potential challenges beyond.

Factors associated with hospitalizations and deaths of pregnant women from Paraná due to COVID-19: a cross-sectional study

OBJECTIVE

To analyze the factors associated with hospitalization in the ward and intensive care unit (ICU), and with death from COVID-19 in pregnant women with confirmed cases.

METHODS

Observational, cross-sectional study, carried out with data from pregnant women with a confirmed case of COVID-19 from the Influenza Epidemiological Surveillance Information System and the Paraná's state COVID-19 notification system. The association between the independent and dependent variables (hospitalization in the ward and ICU, and death) was investigated using the Poisson regression model with robust variance.

RESULTS

4,719 pregnant women comprised the study population. 9.6 and 5.1% were hospitalized in wards and ICU, respectively. 1.9% died. There was an association between advanced maternal age and hospitalization in wards (PR=1.36; 95%CI 1.10-1.62) and ICU (PR=2.25; 95%CI 1.78-2.71), and death (PR=3.22; 95%CI 2.30-4.15). An association was found between the third trimester and hospitalization in wards (PR=5.06; 95%CI 2.82-7.30) and ICU (PR=6.03; 95%CI 3.67-8.39) and death (PR=13.56; 95%CI 2.90-24.23). The second trimester was associated with ICU admission (PR=2.67; 95%CI 1.36-3.99). Pregnant women with cardiovascular disease had a higher frequency of hospitalization in wards (PR=2.24; 95%CI 1.43-3.05) and ICU (PR=2.66; 95%CI 1.46-3.87). Obesity was associated with ICU admission (PR=3.79; 95%CI 2.71-4.86) and death (PR=5.62; 95%CI 2.41-8.83).

CONCLUSIONS

Advanced maternal age, the end of the gestational period and comorbidities were associated with severe COVID-19.

From pandemic to syndemic: microbiota, pregnancy, and environment at a crossroad

Aim: SARS-CoV2 is the latest pandemic that have plagued the socio-health system as an epiphenomenon resulting from planetary resources abuse, crucial for biodiversity. The Anthropocene best defines the present epoch in which human activity irreversibly manipulates intricate and delicate geological and biological balances established over eons. The devastating ecological and socio-economic implications of COVID-19, underline the importance of updating the present pandemic framework to a syndemic. This paper stems from the need to suggest to scientists, doctors, and patients a mission that integrates responsibility from individual to collective health, from present to trans-generational, from human to the entire biotic network. Today's choices are crucial for the perspective on all levels: political, economic, and health as well as cultural.Methods: Research on PubMed and other specific web-sites journal was performed on the topic "Microbiota", "Covid-19", "Pandemic", "Zoonosis", "SARS-CoV-2", "Environmental Pollutants", "Epigenetics", "Fetal Programming", "Human Extinction". Data collected were analysed for an integrative model of interconnection between environment, pregnancy, SARS-CoV-2 infection, and microbiota. Moreover, systematic literature review allowed to summarise in a table information about the worst pandemics that afflicted the human species recently.Results: This paper offers a broad view of the current pandemic starting with pregnancy, the moment when a new life begins and the health trajectories of the unborn child are defined, which will inevitably have repercussions on his well-being. The fundamental role of the biodiversity-rich microbiota in avoiding the development of severe infectious diseases, is therefore highlighted. It is imperative to adjust the current reductionist paradigm based on mostly immediate symptom management towards a broader understanding of the spatial interconnection of ecological niches with human health and the impacts of today's choices on the future. Health and healthcare are elitist rather than egalitarian, therefore focusing on environmental health forces us to make a concerted and systemic effort that challenges political and economic barriers, which are biologically senseless. A healthy microbiota is essential to well-being, both by preventing chronic degenerative conditions, the infectiousness and pathogenicity of bacterial and viral diseases. SARS-CoV-2 should not be an exception. The human microbiota, forged by the first 1,000 days of life, is fundamental in shaping the health-disease trajectories, and by the everlasting exposome that is dramatically affected by the ecological disaster. Individual health is one world health whereas single and global well-being are interdependent in a space-time perspective.Conclusions: Is it not a convenient reductionism not to consider the COVID-19 emergency as a bio-social epiphenomenon of a far more devastating and multi-faceted crisis whose common denominator is the global biotic network loss of which humans are still part?

Umbilical cord clamping in the early phases of the COVID-19 era - a systematic review and meta-analysis of reported practice and recommendations in guidelines

OBJECTIVES

At the beginning of the COVID-19 pandemic, delayed umbilical cord clamping (CC) at birth may have been commonly discouraged despite a lack of convincing evidence of mother-to-neonate SARS-CoV-2 transmission. We aimed to systematically review guidelines, and reports of practice and to analyze associations between timing of CC and mother-to-neonate SARS-CoV-2 transmission during the early phases of the pandemic.

METHODS

Major databases were searched from December 1, 2019, to July 20, 2021.

INCLUSION

studies and guidelines describing CC practice in women with SARS-CoV-2 infection during pregnancy until 2 postnatal days, giving birth to live-born neonates.

EXCLUSION

no extractable data. Two reviewers independently screened studies for eligibility and assessed study quality. Pooled prevalence rates were calculated.

RESULTS

Forty-eight studies (1476 neonates) and 40 guidelines were included. Delayed CC was recommended in 70.0% of the guidelines. Nevertheless, delayed CC was reported less often than early CC: 262/1476 (17.8%) vs 511/1476 (34.6%). Neonatal SARS-CoV-2 positivity rates were similar following delayed (1.2%) and early CC (1.3%). Most SARS-CoV-2 transmissions (93.3%) occurred in utero.

CONCLUSION

Delayed CC did not seem to increase mother-to-neonate SARS-CoV-2 transmission. Due to its benefits, it should be encouraged even in births where the mother has a SARS-CoV-2 infection.

Implications for implementation and adoption of telehealth in developing countries: a systematic review of China's practices and experiences

The rapid advancement of telehealth technologies has the potential to revolutionize healthcare delivery, especially in developing countries and resource-limited settings. Telehealth played a vital role during the COVID-19 pandemic, supporting numerous healthcare services. We conducted a systematic review to gain insights into the characteristics, barriers, and successful experiences in implementing telehealth during the COVID-19 pandemic in China, a representative of the developing countries. We also provide insights for other developing countries that face similar challenges to developing and using telehealth during or after the pandemic. This systematic review was conducted through searching five prominent databases including PubMed/MEDLINE, Embase, Scopus, Cochrane Library, and Web of Science. We included studies clearly defining any use of telehealth services in all aspects of health care during the COVID-19 pandemic in China. We mapped the barriers, successful experiences, and recommendations based on the Consolidated Framework for Implementation Research (CFIR). A total of 32 studies met the inclusion criteria. Successfully implementing and adopting telehealth in China during the pandemic necessitates strategic planning across aspects at society level (increasing public awareness and devising appropriate insurance policies), organizational level (training health care professionals, improving workflows, and decentralizing tasks), and technological level (strategic technological infrastructure development and designing inclusive telehealth systems). WeChat, a widely used social networking platform, was the most common platform used for telehealth services. China's practices in addressing the barriers may provide implications and evidence for other developing countries or low-and middle- income countries (LMICs) to implement and adopt telehealth systems.

Different impact of COVID-19 on symptomatic pregnant and postpartum women in low-income countries and low- and middle-income countries

The adverse outcomes of COVID‐19 among pregnant women have been pronounced in the low‐income countries compared with low‐ and middle‐income countries.

Evolution of National Guidelines on Medicines Used to Treat COVID-19 in Pregnancy in 2020-2022: A Scoping Review

The lack of inclusion of pregnant women in clinical trials evaluating the effectiveness of medicines to treat COVID-19 has made it difficult to establish evidence-based treatment guidelines for pregnant women. Our aim was to provide a review of the evolution and updates of the national guidelines on medicines used in pregnant women with COVID-19 published by the obstetrician and gynecologists' societies in thirteen countries in 2020-2022. Based on the results of the RECOVERY (Randomized Evaluation of COVID-19 Therapy) trial, the national societies successively recommended against prescribing hydroxychloroquine, lopinavir-ritonavir and azithromycin. Guidelines for remdesivir differed completely between countries, from compassionate or conditional use to recommendation against. Nirmatrelvir-ritonavir was authorized in Australia and the UK only in research settings and was no longer recommended in the UK at the end of 2022. After initial reluctance to use corticosteroids, the results of the RECOVERY trial have enabled the recommendation of dexamethasone in case of severe COVID-19 since mid-2020. Some societies recommended prescribing tocilizumab to pregnant patients with hypoxia and systemic inflammation from June 2021. Anti-SARS-CoV-2 monoclonal antibodies were authorized at the end of 2021 with conditional use in some countries, and then no longer recommended in Belgium and the USA at the end of 2022. The gradual convergence of the recommendations, although delayed compared to the general population, highlights the importance of the inclusion of pregnant women in clinical trials and of international collaboration to improve the pharmacological treatment of pregnant women with COVID-19.

Substantial increase in stillbirth rate during the COVID-19 pandemic: results from a population-based study in the Indian state of Bihar

INTRODUCTION

We report on the stillbirth rate (SBR) and associated risk factors for births during the COVID-19 pandemic, and change in SBR between prepandemic (2016) and pandemic periods in the Indian state of Bihar.

METHODS

Births between July 2020 and June 2021 (91.5% participation) representative of Bihar were listed. Stillbirth was defined as fetal death with gestation period of ≥7 months where the fetus did not show any sign of life. Detailed interviews were conducted for all stillbirths and neonatal deaths, and for 25% random sample of surviving live births. We estimated overall SBR, and during COVID-19 peak and non-peak periods per 1000 births. Multiple logistic regression models were run to assess risk factors for stillbirth. The change in SBR for Bihar from 2016 to 2020-2021 was estimated.

RESULTS

We identified 582 stillbirths in 30 412 births with an estimated SBR of 19.1 per 1000 births (95% CI 17.7 to 20.7); SBR was significantly higher in private facility (38.4; 95% CI 34.3 to 43.0) than in public facility (8.6; 95% CI 7.3 to 10.1) births, and for COVID-19 peak (21.2; 95% CI 19.2 to 23.4) than non-peak period (16.3; 95% CI 14.2 to 18.6) births. Pregnancies with the last pregnancy trimester during the COVID-19 peak period had 40.4% (95% CI 10.3% to 70.4%) higher SBR than those who did not. Risk factor associations for stillbirths were similar between the COVID-19 peak and non-peak periods, with gestation age of <8 months with the highest odds of stillbirth followed by referred deliveries and deliveries in private health facilities. A statistically significant increase of 24.3% and 68.9% in overall SBR and intrapartum SBR was seen between 2016 and 2020-2021, respectively.

CONCLUSIONS

This study documented an increase in SBR during the COVID-19 pandemic as compared with the prepandemic period, and the varied SBR based on the intensity of the COVID-19 pandemic and by the place of delivery.

Infective Endocarditis during Pregnancy-Keep It Safe and Simple!

The diagnosis of infective endocarditis (IE) during pregnancy is accompanied by a poor prognosis for both mother and fetus in the absence of prompt management by multidisciplinary teams. We searched the electronic databases of PubMed, MEDLINE and EMBASE for clinical studies addressing the management of infective endocarditis during pregnancy, with the aim of realizing a literature review ranging from risk factors to diagnostic investigations to optimal therapeutic management for mother and fetus alike. The presence of previous cardiovascular pathologies such as rheumatic heart disease, congenital heart disease, prosthetic valves, hemodialysis, intravenous catheters or immunosuppression are the main risk factors predisposing patients to IE during pregnancy. The identification of modern risk factors such as intracardiac devices and intravenous drug administration as well as genetic diagnostic methods such as cell-free deoxyribonucleic acid (DNA) next-generation sequencing require that these cases be addressed in multidisciplinary teams. Guiding treatment to eradicate infection and protect the fetus simultaneously creates challenges for cardiologists and gynecologists alike.

Severe Acute Respiratory Syndrome Coronavirus 2 Infection Symptoms in Pregnancy and Maternal and Neonatal Complications Due to COVID-19: A Systematic Review

Background

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnant women is associated with severe maternal and neonatal complications including maternal and newborn death.

Aims

This review aimed to assess the SARS-CoV-2 infection symptoms during pregnancy as well as maternal and neonatal complications in Iran.

Settings and Design

A developing and low-income country and a systematic review.

Materials and Methods

International scientific databases including PubMed, Web of Science, Scopus and Google Scholar were searched in a systematic review manner. Two independent researchers were checked and identified articles from September 2019 to September 2022 based on eligibility criteria and quality appraisal. The results of review were reported in two sections including maternal and neonatal outcomes.

Statistical Analysis Used

Descriptive statistics was used for statistical analysis.

Results

Seventeen studies including 870 pregnant mothers with COVID-19 met the eligibility criteria and were reviewed. The main maternal consequences of COVID-19 were intensive care unit (ICU) admission, pre-term delivery, maternal death, pre-mature rupture of membranes, pre-eclampsia, intrauterine growth retardation and stillbirth. Neonatal ICU admission, newborn death, neonatal sepsis, low birth weight and respiratory distress syndrome, tachypnoea, asphyxia and pneumothorax were the most common outcomes of COVID-19 infection in offspring of pregnant subjects.

Conclusion

Pregnant mothers with COVID-19 infection are at higher risk of being admitted to the ICU and mechanical ventilation and consequently maternal and neonatal death. Comparing the maternal and foetal consequences in different ethnicities, regions and countries may be related to the socioeconomic status of people and should be considered with respect to different determines. Moreover, the maternal and neonatal complications due to COVID-19 infection in Iran and other developing countries seem to be higher than other countries.

COVID-19 antibody positivity over time and pregnancy outcomes in seven low-and-middle-income countries: A prospective, observational study of the Global Network for Women's and Children's Health Research

OBJECTIVES

To determine COVID-19 antibody positivity rates over time and relationships to pregnancy outcomes in low- and middle-income countries (LMICs).

DESIGN

With COVID-19 antibody positivity at delivery as the exposure, we performed a prospective, observational cohort study in seven LMICs during the early COVID-19 pandemic.

SETTING

The study was conducted among women in the Global Network for Women's and Children's Health's Maternal and Newborn Health Registry (MNHR), a prospective, population-based study in Kenya, Zambia, the Democratic Republic of the Congo (DRC), Bangladesh, Pakistan, India (two sites), and Guatemala.

POPULATION

Pregnant women enrolled in an ongoing pregnancy registry at study sites.

METHODS

From October 2020 to October 2021, standardised COVID-19 antibody testing was performed at delivery among women enrolled in MNHR. Trained staff masked to COVID-19 status obtained pregnancy outcomes, which were then compared with COVID-19 antibody results.

MAIN OUTCOME MEASURES

Antibody status, stillbirth, neonatal mortality, maternal mortality and morbidity.

RESULTS

At delivery, 26.0% of women were COVID-19 antibody positive. Positivity increased over the four time periods across all sites: 13.8%, 15.4%, 21.0% and 40.9%. In the final period, positivity rates were: DRC 27.0%, Kenya 33.1%, Pakistan 32.8%, Guatemala 37.0%, Zambia 37.8%, Bangladesh 47.2%, Nagpur, India 57.4% and Belagavi, India 62.4%. Adjusting for site and maternal characteristics, stillbirth, neonatal mortality, low birthweight and preterm birth were not significantly associated with COVID-19. The adjusted relative risk (aRR) for stillbirth was 1.27 (95% CI 0.95-1.69). Postpartum haemorrhage was associated with antibody positivity (aRR 1.44; 95% CI 1.01-2.07).

CONCLUSIONS

In pregnant populations in LMICs, COVID-19 antibody positivity has increased. However, most adverse pregnancy outcomes were not significantly associated with antibody positivity.

Clinical-epidemiological characteristics and maternal-foetal outcomes in pregnant women hospitalised with COVID-19 in Venezuela: a retrospective study

BACKGROUND

In low- and middle-income countries, pregnant women and newborns are more vulnerable to adverse outcomes from coronavirus disease 2019 (COVID-19). However, in Venezuela, there are no integrated data in a national surveillance system to identify the clinical-epidemiological characteristics and maternal-foetal outcomes of pregnant women hospitalised with COVID-19.

METHODS

A retrospective study was conducted among Venezuelan pregnant women hospitalised with COVID-19 seen at the "Ruiz y Páez" University Hospital Complex and the San Cristobal Central Hospital between June 2020 and September 2021. Information was obtained from physical and digitised clinical records using a purpose-designed proforma to collect epidemiological, clinical, paraclinical, treatment, obstetric and perinatal complications, and maternal-foetal outcomes data.

RESULTS

A total of 80 pregnant women with confirmed severe acute respiratory syndrome coronavirus 2 infection were seen within the study period, 59 (73.8%) survived and 21 (26.2%) died. The median (interquartile range) age was 29 (23-33) years, the majority being in the third trimester of pregnancy (81.2%; n = 65). Interestingly, four (5%) pregnant women were co-infected with malaria by Plasmodium vivax and three (3.8%) with syphilis. The most frequent symptoms were fever (75%; n = 60), dry cough (68.8%; n = 55), dyspnoea (55%; n = 44), and headache (53.8%; n = 43). The most frequent maternal complications were anaemia (51.5%; n = 66) and hypertensive disorders of pregnancy (17.5%; n = 14). The most frequent perinatal complications were preterm delivery (39.2%; n = 20/51) and oligohydramnios (31.3%; n = 25). A total of 29 (36.3%) adverse foetal outcomes were documented, 21 stillbirth and eight abortions.

CONCLUSION

This is the first study to describe the clinical-epidemiological behaviour of COVID-19 in hospitalised Venezuelan pregnant women. Anaemia, hypertensive disorders of pregnancy, oligohydramnios, and low birth weight were the most frequent maternal-foetal complications in this population of pregnant women.

Antepartum SARS-CoV-2 infection and adverse birth outcomes in South African women

Background

SARS-CoV-2 infection in pregnant women has been associated with severe illness in the women and higher rates of premature delivery. There is, however, paucity of data on the impact of the timing of SARS-CoV-2 infection and on symptomatic or asymptomatic infections on birth outcomes. Data from low-middle income settings is also lacking.

Methods

We conducted a longitudinal study from April 2020 to March 2021, in South Africa, where symptomatic or asymptomatic pregnant women were investigated for SARS-CoV-2 infection during the antepartum period. We aimed to evaluate if there was an association between antepartum SARS-CoV-2 infection on birth outcomes. SARS-CoV-2 infection was investigated by nucleic acid amplification test (NAAT), histological examination was performed in a sub-set of placentas.

Results

Overall, 793 women were tested for SARS-CoV-2 antenatally, including 275 (35%) who were symptomatic. SARS-CoV-2 infection was identified in 138 (17%) women, of whom 119 had symptoms (COVID-19 group) and 19 were asymptomatic. The 493 women who were asymptomatic and had a negative SARS-CoV-2 NAAT were used as the referent comparator group for outcomes evaluation. Women with COVID-19 compared with the referent group were 1.66-times (95% confidence interval (CI) = 1.02-2.71) more likely to have a low-birthweight newborn (30% vs 21%) and 3.25-times more likely to deliver a very low-birthweight newborn (5% vs 2%). Similar results for low-birthweight were obtained comparing women with SARS-CoV-2 confirmed infection (30%) with those who had a negative NAAT result (22%) independent of symptoms presentation. The placentas from women with antenatal SARS-CoV-2 infection had higher percentage of chorangiosis (odds ratio (OR) = 3.40, 95% CI = 1.18-.84), while maternal vascular malperfusion was more frequently identified in women who tested negative for SARS-CoV-2 (aOR = 0.28, 95% CI = 0.09-0.89).

Conclusions

Our study demonstrates that in a setting with high HIV infection prevalence and other comorbidities antenatal SARS-CoV-2 infection was associated with low-birthweight delivery.

COVID-19 in Pregnancy

Coronavirus disease-2019 (COVID-19) infection during pregnancy is associated with severe complications and adverse effects for the mother, the fetus, and the neonate. The frequency of these outcomes varies according to the region, the gestational age, and the presence of comorbidities. Many COVID-19 interventions, including oxygen therapy, high-flow nasal cannula, and invasive mechanical ventilation, are challenging and require understanding physiologic adaptations of pregnancy. Vaccination is safe during pregnancy and lactation and constitutes the most important intervention to reduce severe disease and complications.

Effect of the COVID-19 pandemic on maternal healthcare indices in Southern Iran: an interrupted time series analysis

OBJECTIVES

Epidemics are anticipated to influence the coverage of health services. We assessed the impact of the COVID-19 pandemic on maternal healthcare indices and care providers' performance.

SETTING

1801 maternal healthcare centres under the auspices of Shiraz University of Medical Sciences, Shiraz, Southern Iran.

PARTICIPANTS

Approximately 63 000 pregnant women.

PRIMARY AND SECONDARY OUTCOME MEASURES

In this prospective ecological study, interrupted time series analysis was used to model and compare the trend of maternal healthcare indices before and after the COVID-19 pandemic announcement.

RESULTS

The results showed a significant drop in count of preconception healthcare visits, first routine laboratory tests, first trimester prenatal care, first trimester sonography, prenatal screening for birth defects at weeks 11-13, prenatal care visits at weeks 16-20, second routine laboratory tests, second trimester sonography, prenatal care visits at weeks 24-30, prenatal care visits at weeks 31-34, postpartum care visits at days 10-15 and postpartum care visits at days 30-42 with the start of the COVID-19 pandemic (-50% (95% CI -48.68% to -51.36%), -19.67% (95% CI -22.12% to -17.15%), -25.88% (95% CI -28.46% to -23.21%), -23.84% (95% CI -26.26% to -21.34%), -20.16% (95% CI -23.01% to -17.20%), -18.53% (95% CI -21.25% to -15.71%), -28.63% (95% CI -31.03% to -26.14%), -27.48% (95% CI -30.07% to -24.79%), -31.08% (95% CI -33.43% to -28.61%), -31.84% (95% CI -34.35% to -29.23%), 32.55% (95% CI -35.12% to -29.89%) and -39.28% (95% CI -41.59% to -36.88%), respectively). Nevertheless, the trend in coverage of these services showed recovery in the subsequent months (8.36%, 10.55%, 5.74%, 8.01%, 4.40%, 5.06%, 11.20%, 7.58%, 7.38%, 7.80%, 9.59% and 9.61% per month, respectively).

CONCLUSIONS

Using ecological data during the COVID-19 pandemic era, we observed a 'level change and slope change' as the major pattern of interruption of maternal healthcare coverage, indicating a possible indirect effect rather than a causative relationship. Such relative predictability might assist with future pandemic planning.

An outbreak of infection due to severe acute respiratory corona virus-2 in a neonatal unit from a low and middle income setting

Introduction

The provision of kangaroo mother care (KMC) involving continuous skin-to-skin care (SSC) is an important intervention in neonatal care, which is recommended even when women are infected with severe acute respiratory syndrome coronavirus (SARS-CoV-2). We report on a nosocomial outbreak of SARS-CoV-2 infections in a KMC ward.

Methods

Contact tracing was conducted following the diagnosis of SARS-CoV-2 in a mother lodging in the KMC ward. All mother-newborn dyads in the KMC and healthcare workers (HCW) were tested for SARS-CoV-2 within 24-72 h of diagnosing the index case. Nasopharyngeal swab samples were obtained and tested from contacts, with a nucleic acid amplification test (NAAT) assay. Next-generation sequencing was done on positive samples. The secondary attack rate (SAR) was calculated assuming that the mother who presented with symptoms was the source of infection.

Results

Twelve (70.6%) of 17 mothers and 8 (42.1%) of 19 neonates who were in the KMC ward with the index case were found to be positive with SARS-CoV-2. Seven (87.5%) of the 8 neonates who tested positive had mothers who also tested positive. Seventy-five percent (9/12) of the mothers and 62.5% (5/8) of the neonates who tested positive were asymptomatic. Eight (27.6%) of 29 HCW were found to be positive and were all asymptomatic. One neonate died from Acinetobacter baumannii sepsis, and his post-mortem lung histopathology showed features compatible with SARS-CoV-2 pneumonia. The sequencing of 13 specimens, which included 1 mother-newborn dyad, indicated clustering to the same phylogenetic lineage with identical mutations. In assessing for factors contributing to this outbreak, it was found that spaces between beds were less than 1 m and mothers had their meals around the same table at the same time.

Conclusion

We report on a nosocomial outbreak of SARS-CoV-2 in a KMC ward, affecting a high number of mothers and neonates, and to a lesser extent HCWs. Although it is difficult to point to the index case as the source of this outbreak, as asymptomatic individuals can spread infection, the inadequate adherence to non-pharmaceutical interventions was assessed to have contributed to the spread of infection. This highlights the need for awareness and adherence to mitigation strategies to avoid SARS-CoV-2 outbreaks.

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

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

Maternal and neonatal outcomes of COVID-19 co-infection in pregnant women with chronic hepatitis B virus infection: A prospective cohort study

Co‐infection with COVID‐19 in pregnant women with pre‐existing HBV infection led to a higher proportion of preterm deliveries and lower mean birth weight.

COVID-19 related maternal mortality cases in associated with Delta and Omicron waves and the role of lung ultrasound

Objective

To present coronavirus disease-2019 (COVID-19) related maternal mortality in relation to Delta and Omicron waves and to investigate the role of lung ultrasound (LUS) in estimating mortality.

Materials and Methods

This retrospective cohort study was conducted in the obstetrics and gynecology clinic of a tertiary pandemic hospital between March 2020 and January 2022. The hospitalized pregnant women with COVID-19 diagnosis and maternal deaths were studied in relation with Delta and Omicron waves. The relationship between LUS scores of hospitalized patients and maternal mortality was explored.

Results

Thousand and sixty-five pregnant women were hospitalized because of COVID-19 infection. Fifty-one (4.79%) of these patients had critical sickness, 96 (9.01%) of them had severe illness, 62 (5.82%) of them were admitted to the intensive care unit and 28 (2.63%) of all hospitalized pregnant women had died. Of the 1.065 patients, 783 (73.5%) were hospitalized before the Delta wave and the maternal mortality rate was 1.28% (10/783), 243 (22.8%) were hospitalized during the Delta wave and the maternal mortality rate was 7% (17/243) [relative risk (RR)=5.478, 95% confidence interval (CI) (2.54-11.8), z=4.342, p<0.001]. During the Omicron wave 39 (3.66%) patients were hospitalized and the maternal mortality rate was 2.56% (1/39). Maternal mortality rates, according to LUS scores, were 0.37% (1/273) for LUS 0, 0.72% (2/277) for LUS 1, 2.58% (10/387) for LUS 2 and 11.72% (15/128) for LUS 3 respectively (LUS 3 vs. others; maternal mortality: RR=8.447, 95% CI (4.11-17.34), z=5.814, p<0.0001). There were no vaccinated patients in the study cohort.

Conclusion

The maternal mortality rate was relatively high, particularly during the Delta wave at our referral center. The Delta wave, delayed vaccination and vaccine hesitancy of pregnant women might have important roles in maternal mortality. Higher LUS scores should warn clinicians of an increased risk of maternal death.

COVID-19 disease and vaccination in pregnant and lactating women

Background

More than 325,000 cases of coronavirus disease 2019 (COVID‐19) have been reported among pregnant women in the Americas.

Aims

This review examines the impact of COVID‐19 in pregnant women and describes available evidence on the safety, effectiveness, and immune response(s) to vaccination among pregnant and lactating women.

Content

Multiple studies indicate that pregnant women are more susceptible to adverse COVID‐19 outcomes, including hospitalization, intensive care unit admission, and invasive ventilation than non‐pregnant women with COVID‐19. Furthermore, COVID‐19 in pregnancy is associated with adverse maternal and neonatal outcomes. Adverse COVID‐19 outcomes appear to disproportionately affect pregnant women from low‐ and middle‐income countries, likely reflecting inequities in access to quality healthcare. Despite the absence of safety and efficacy data from randomized clinical trials in this subpopulation, observational studies and data from pregnancy registries thus far have demonstrated that vaccination of pregnant or lactating women against COVID‐19 is safe, effective, and results in robust immune responses including transfer of antibodies to the newborn via the placenta and breast milk, respectively.

Implications

These data support vaccination recommendations intending to help protect these vulnerable individuals against COVID‐19 and its sequelae. Randomized clinical studies will further evaluate the safety and immunogenicity of COVID‐19 vaccines in these populations. This review examines the impact of COVID‐19 in pregnant women and describes available evidence on the safety, effectiveness, and immune response(s) to vaccination among pregnant and lactating women.

WHO Standards-based questionnaire to measure health workers' perspective on the quality of care around the time of childbirth in the WHO European region: development and mixed-methods validation in six countries

OBJECTIVES

Develop and validate a WHO Standards-based online questionnaire to measure the quality of maternal and newborn care (QMNC) around the time of childbirth from the health workers' perspective.

DESIGN

Mixed-methods study.

SETTING

Six countries of the WHO European Region.

PARTICIPANTS AND METHODS

The questionnaire is based on lessons learnt in previous studies, and was developed in three sequential phases: (1) WHO Quality Measures were prioritised and content, construct and face validity were assessed through a Delphi involving a multidisciplinary board of experts from 11 countries of the WHO European Region; (2) translation/back translation of the English version was conducted following The Professional Society for Health Economics and Outcomes Research guidelines; (3) internal consistency, intrarater reliability and acceptability were assessed among 600 health workers in six countries.

RESULTS

The questionnaire included 40 items based on WHO Standards Quality Measures, equally divided into four domains: provision of care, experience of care, availability of human and physical resources, organisational changes due to COVID-19; and its organised in six sections. It was translated/back translated in 12 languages: Bosnian, Croatian, French, German, Italian, Norwegian, Portuguese, Romanian, Russian, Slovenian, Spanish and Swedish. The Cronbach's alpha values were ≥0.70 for each questionnaire section where questions were hypothesised to be interrelated, indicating good internal consistence. Cohen K or Gwet's AC1 values were ≥0.60, suggesting good intrarater reliability, except for one question. Acceptability was good with only 1.70% of health workers requesting minimal changes in question wording.

CONCLUSIONS

Findings suggest that the questionnaire has good content, construct, face validity, internal consistency, intrarater reliability and acceptability in six countries of the WHO European Region. Future studies may further explore the questionnaire's use in other countries, and how to translate evidence generated by this tool into policies to improve the QMNC.

Increased spontaneous preterm births during the second wave of the coronavirus disease 2019 pandemic in India

OBJECTIVE

To compare spontaneous preterm birth (SPTB) and iatrogenic preterm birth (IPTB) rates during both waves of the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

Retrospective analysis of the PregCovid registry of pregnant women with COVID-19 was performed at a dedicated COVID-19 hospital in Mumbai, India. The data of 1630 women were analyzed for this study between April 4, 2020 and July 4, 2021. Prepandemic data were analyzed and compared with pandemic data. Main outcome measure was spontaneous preterm birth rate.

RESULTS

Preterm deliveries were higher during the second wave (46/329; 14%) compared with the first wave (82/807; 10.2%) of the COVID-19 pandemic (P = 0.065). Higher SPTBs were reported during the second wave than the first wave (12.5% versus 8.3%) (P = 0.03) as well as the prepandemic period (12.5% versus 10.5%) (P = 0.286). IPTBs were significantly lower in the pandemic period than in the prepandemic period (1.8 versus 3.3) (P = 0.012).

CONCLUSION

In Mumbai, India, we found an unusual change in SPTBs during the 6 months of the second wave of COVID-19 compared with the previous 10 months of the first wave of pandemic and 1 year of prepandemic.

Maternal and fetal outcomes of COVID-19 infection in pregnant women with chronic rheumatic heart disease in a South Asian population: A case series

Rheumatic heart disease (RHD) is associated with an increased risk of adverse maternal, fetal, and neonatal outcomes, particularly in developing countries. The current COVID-19 pandemic has also affected pregnant women, probably increasing the adverse effects. It is speculated that COVID-19 infection in pregnant women would further increase the risk of complications. However, factual data is still lacking, especially from resource-constrained countries. We conducted a case series of 20 pregnant women with RHD and COVID-19 infection and compared their outcomes with 40 with RHD but without COVDI-19. We observed a high risk of adverse cardiac and pregnancy effects across the whole cohort of 60 patients. However, the comparative study between the two groups failed to show any incremental risk of complications due to COVID-19 infection. Although the sample size was limited; the results are encouraging, particularly for developing countries.

Protocol for a prospective, hospital-based registry of pregnant women with SARS-CoV-2 infection in India: PregCovid Registry study

INTRODUCTION

Pregnant women are at increased risk of contracting COVID-19 due to several factors and therefore require special attention. However, the consequences of the COVID-19 pandemic on pregnant women and their newborns remain uncharted. The PregCovid registry aims to document the impact of SARS-CoV-2 infection on pregnant, postpartum women and their newborns. The aim of the registry is also to determine mother-to-child transmission of SARS-CoV-2 infection in India.

METHODS AND ANALYSIS

PregCovid is a hospital-based registry for capturing information of pregnant, postpartum women with COVID-19 and their newborns in India. Medical case records of pregnant and postpartum women with a laboratory-confirmed diagnosis of COVID-19 will be captured in real-time using an online electronic patient record software. The data analysis will be carried out for symptoms, the severity of COVID-19, pregnancy complications, maternal morbidity and mortality, neonatal complications, mother-to-child transmission, etc. Data analysis will be carried out for different waves of the COVID-19 pandemic for rapid response and developing strategies well in advance to manage pregnant women infected with SARS-CoV-2. The evidence generated from the registry will be regularly shared with the appropriate authorities for policy decisions.

Effects of Vertical Transmission of Respiratory Viruses to the Offspring

Overt and subclinical maternal infections in pregnancy can have multiple and significant pathological consequences for the developing fetus, leading to acute perinatal complications and/or chronic disease throughout postnatal life. In this context, the current concept of pregnancy as a state of systemic immunosuppression seems oversimplified and outdated. Undoubtedly, in pregnancy the maternal immune system undergoes complex changes to establish and maintain tolerance to the fetus while still protecting from pathogens. In addition to downregulated maternal immunity, hormonal changes, and mechanical adaptation (e.g., restricted lung expansion) make the pregnant woman more susceptible to respiratory pathogens, such as influenza virus, respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Depending on the infectious agent and timing of the infection during gestation, fetal pathology can range from mild to severe, and even fatal. Influenza is associated with a higher risk of morbidity and mortality in pregnant women than in the general population, and, especially during the third trimester of pregnancy, mothers are at increased risk of hospitalization for acute cardiopulmonary illness, while their babies show higher risk of complications such as prematurity, respiratory and neurological illness, congenital anomalies, and admission to neonatal intensive care. RSV exposure in utero is associated with selective immune deficit, remodeling of cholinergic innervation in the developing respiratory tract, and abnormal airway smooth muscle contractility, which may predispose to postnatal airway inflammation and hyperreactivity, as well as development of chronic airway dysfunction in childhood. Although there is still limited evidence supporting the occurrence of vertical transmission of SARS-CoV-2, the high prevalence of prematurity among pregnant women infected by SARS-CoV-2 suggests this virus may alter immune responses at the maternal-fetal interface, affecting both the mother and her fetus. This review aims at summarizing the current evidence about the short- and long-term consequences of intrauterine exposure to influenza, RSV, and SARS-CoV-2 in terms of neonatal and pediatric outcomes.

Obstetric and perinatal outcomes of pregnancies with COVID 19: a systematic review and meta-analysis

OBJECTIVE

This meta-analysis aimed at comparing obstetric and perinatal outcomes in laboratory-tested pregnant women for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection before delivering.

METHOD

We performed a comprehensive systematic review of electronic databases for studies reporting pregnant women with and without SARS-CoV-2 infection, as determined by polymerase chain reaction (PCR) before delivery, during the pandemic period published up to June 25, 2021. Results are reported as mean difference (MD) or odds ratio (OR) and their 95% confidence interval (CI).

RESULTS

Seventeen observational studies with low to moderate risk of bias, reported on 2,769 pregnant women with a positive SARS-CoV-2 PCR test and 13,807 with a negative test. Pregnant women with a positive PCR test delivered at an earlier gestational age (MD -0.19; 95% CI -0.36 to -0.02 weeks), smoked less (OR 0.75; 95% CI 0.61-0.94) and were associated with higher odds for preeclampsia (OR 1.30; 95% CI 1.09-1.54), NICU admissions (OR 2.37; 95% CI 1.18-4.76), stillbirths (OR 2.70; 95% CI, 1.38-5.29), and perinatal mortality (OR 3.23; 95% CI 1.23-8.52). There were no significant differences between positive and negative tested women in terms of nulliparity, multiple pregnancies, gestational diabetes, route of delivery, labor induction, preterm birth, infant birth weight, 5 min Apgar scores < 7, small-for-gestational-age infants and fetal malformations. Eleven studies included neonatal PCR SARS-CoV-2 testing which was performed on 129 infants, of which 20 were positive.

CONCLUSION

Positive SARS-CoV-2 tested pregnant women had higher odds for preeclampsia/hypertensive disorders of pregnancy, NICU admissions, stillbirths and perinatal mortality.

Global Perspectives on Immunization Against SARS-CoV-2 During Pregnancy and Priorities for Future Research: An International Consensus Paper From the World Association of Infectious Diseases and Immunological Disorders

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy is associated with a higher risk for severe morbidity and mortality when compared with infection in non-pregnant women of childbearing age. An increasing number of countries recommend immunization against SARS-CoV-2 in pregnant women. Recent studies provide preliminary and supportive evidence on safety, immunogenicity and effectiveness of coronavirus disease 2019 (COVID-19) vaccines in pregnant women; however, important knowledge gaps remain which warrant further studies. This collaborative consensus paper provides a review of the current literature on COVID-19 vaccines in pregnant women, identifies knowledge gaps and outlines priorities for future research to optimize protection against SARS-CoV-2 in the pregnant women and their infants.

Compliance with COVID-19 Preventive Measures and Associated Factors Among Women Attending Antenatal Care at Public Health Facilities of Debre Berhan Town, Ethiopia

BACKGROUND

Coronavirus disease-2019 (COVID-19) is a highly contagious and cause for the death of many people worldwide. Due to physiological immunosuppressive state and mechanical alteration, pregnant women are at a higher risk of severe illness and adverse maternal and fetal outcomes from COVID-19 than non-pregnant women. Compliance with the preventive measures is essential to control COVID-19 related consequences. Therefore, this study aimed to assess compliance with COVID-19 preventive measures among pregnant women attending antenatal care at public facilities of Debre Berhan town, Ethiopia.

METHODS

A facility-based cross-sectional study was conducted from May 1 to 30, 2021 among 402 pregnant mothers. Data were collected via a face-to-face interviewer-administered questionnaire. Then, entered into Epi-Data version 4.6 and exported to SPSS version 25 for data analysis. In multivariable logistic regression analysis, variables with p < 0.05 were declared as statistically significant and the strength of statistical association was measured by adjusted odds ratio (AOR) and 95% confidence interval (CI).

RESULTS

Of the total 396 participants, 222 (56.1%) of women had a good compliance with COVID-19 preventive measures. Maternal age (25-34 years) [AOR: 1.926; 95% CI (1.084, 3.421)] and (≥35 years) [AOR: 3.018; 95% CI (1.53, 5.952)], husband educational status [AOR: 3.68; 95% CI (1.55, 8.737)], had current chronic disease [AOR: 2.516; 95% CI (1.297, 4.883)], and knowledge [AOR: 5.484; 95% CI (3.057, 9.838)] were significant predictors to have good compliance with COVID-19 preventive measures.

CONCLUSION

Although COVID-19 is a global and national agenda, compliance towards its preventive measures was not sufficient enough. Therefore, scale-up the community awareness via media campaign is crucial which will eventually improve compliance. Furthermore, those women who had no pre-existing chronic diseases and those in the young age group should be given special consideration.

Maternal COVID-19 and neonatal hearing loss: a multicentric survey

Purpose

Gestational SARS-Cov-2 infection can impact maternal and neonatal health. The virus has also been reported of causing sensorineural hearing loss. The objective of this study was to determine the possible effect of maternal SARS-COV-2 infection on neonatal hearing as identified during universal hearing screening.

Methods

Retrospective cohort study in two tertiary referral centers including all neonates born from November 2020 through April 1st, 2021 and undergoing the universal hearing screening program. Maternal Covid-19 infection was recorded (timing and severity) and the results of hearing screening of their neonates compared to the incidence of neonatal hearing loss results of the national universal screening program during the same period.

Results

A total of 984 neonates were included (508 males and 476 females). Sixty-three neonates were excluded due to comorbidities which could cause hearing loss. The incidence of failed responses in the community at large was 2.3%. Twenty-seven failed both steps of screening (2.9%; p < 0.2). There were 34 Covid-19 positive mothers (17 in the first trimester, 8 in the second and 9 in the third). Twenty-nine neonates failed the first screening (p < 0.00001) but on further testing only one neonate failed (2.9%).

Conclusion

In this study, neonates born to Covid-19 positive mothers do not seem to have an increased risk of hearing loss. However longer follow-up of these neonates is mandatory to detect any possible delayed effects of the virus.

Clinical characteristics, outcomes, & mortality in pregnant women with COVID-19 in Maharashtra, India: Results from PregCovid registry

Background & objectives

The PregCovid registry was established to document the clinical presentations, pregnancy outcomes and mortality of pregnant and post-partum women with COVID-19.

Methods

The PregCovid registry prospectively collects information in near-real time on pregnant and post-partum women with a laboratory-confirmed diagnosis of SARS-CoV-2 from 19 medical colleges across the State of Maharashtra, India. Data of 4203 pregnant women collected during the first wave of the COVID-19 pandemic (March 2020-January 2021) was analyzed.

Results

There were 3213 live births, 77 miscarriages and 834 undelivered pregnancies. The proportion of pregnancy/foetal loss including stillbirths was six per cent. Five hundred and thirty-four women (13%) were symptomatic, of which 382 (72%) had mild, 112 (21%) had moderate, and 40 (7.5%) had severe disease. The most common complication was preterm delivery (528, 16.3%) and hypertensive disorders in pregnancy (328, 10.1%). A total of 158 (3.8%) pregnant and post-partum women required intensive care, of which 152 (96%) were due to COVID-19 related complications. The overall case fatality rate (CFR) in pregnant and post-partum women with COVID-19 was 0.8 per cent (34/4203). Higher CFR was observed in Pune (9/853, 1.1%), Marathwada (4/351, 1.1%) regions as compared to Vidarbha (9/1155, 0.8%), Mumbai Metropolitan (11/1684, 0.7%), and Khandesh (1/160, 0.6%) regions. Comorbidities of anaemia, tuberculosis and diabetes mellitus were associated with maternal deaths.

Interpretation & conclusions

The study demonstrates the adverse outcomes including severe COVID-19 disease, pregnancy loss and maternal death in women with COVID-19 in Maharashtra, India.
