Vaginal Microbiome and Pregnancy Complications: A Review

Background/Objectives: There are indications that the microbial composition of the maternal mucosal surfaces is associated with adverse events during pregnancy. The aim of this review is to investigate the link between vaginal microbiome alterations and gestational complication risk. Methods: This comprehensive literature review was performed using Medline and Scopus databases. The following search algorithm was used, "Pregnancy Complications" [Mesh] AND (Vagin*), and after the literature screening, 44 studies were included in the final review. Results: The studies that were included investigated the association between vaginal microbial composition and preterm birth, miscarriage, preeclampsia, ectopic pregnancy, gestational diabetes mellitus, chorioamnionitis, and preterm premature rupture of membranes. In most of the studies, it was well established that increased microbial diversity is associated with these conditions. Also, the depletion of Lactobacillus species is linked to most of the gestational complications, while the increased relative abundance and especially Lactobacillus crispatus may exert a protective effect in favor of the pregnant woman. Several pathogenic taxa including Gardnerella, Prevotella, Sneathia, Bacterial Vaginosis-Associated Bacteria-2, Atopobium, and Megasphera seem to be correlated to higher maternal morbidity. Conclusions: Vaginal microbiome aberrations seem to have an association with pregnancy-related adverse events, but more high-quality homogenous studies are necessary to reliably verify this link.

Road to maternal death: the pooled estimate of maternal near-miss, its primary causes and determinants in Africa: a systematic review and meta-analysis

BACKGROUND

Maternal near-miss (MNM) is defined by the World Health Organization (WHO) working group as a woman who nearly died but survived a life-threatening condition during pregnancy, childbirth, or within 42 days of termination of pregnancy due to getting quality of care or by chance. Despite the importance of the near-miss concept in enhancing quality of care and maternal health, evidence regarding the prevalence of MNM, its primary causes and its determinants in Africa is sparse; hence, this study aimed to address these gaps.

METHODS

A systematic review and meta-analysis of studies published up to October 31, 2023, was conducted. Electronic databases (PubMed/Medline, Scopus, Web of Science, and Directory of Open Access Journals), Google, and Google Scholar were used to search for relevant studies. Studies from any African country that reported the magnitude and/or determinants of MNM using WHO criteria were included. The data were extracted using a Microsoft Excel 2013 spreadsheet and analysed by STATA version 16. Pooled estimates were performed using a random-effects model with the DerSimonian Laired method. The I2 test was used to analyze the heterogeneity of the included studies.

RESULTS

Sixty-five studies with 968,555 participants were included. The weighted pooled prevalence of MNM in Africa was 73.64/1000 live births (95% CI: 69.17, 78.11). A high prevalence was found in the Eastern and Western African regions: 114.81/1000 live births (95% CI: 104.94, 123.59) and 78.34/1000 live births (95% CI: 67.23, 89.46), respectively. Severe postpartum hemorrhage and severe hypertension were the leading causes of MNM, accounting for 36.15% (95% CI: 31.32, 40.99) and 27.2% (95% CI: 23.95, 31.09), respectively. Being a rural resident, having a low monthly income, long distance to a health facility, not attending formal education, not receiving ANC, experiencing delays in health service, having a previous history of caesarean section, and having pre-existing medical conditions were found to increase the risk of MNM.

CONCLUSION

The pooled prevalence of MNM was high in Africa, especially in the eastern and western regions. There were significant variations in the prevalence of MNM across regions and study periods. Strengthening universal access to education and maternal health services, working together to tackle all three delays through community education and awareness campaigns, improving access to transportation and road infrastructure, and improving the quality of care provided at service delivery points are key to reducing MNM, ultimately improving and ensuring maternal health equity.

Lifetime risk of maternal near miss morbidity: a novel indicator of maternal health

BACKGROUND

The lifetime risk of maternal death quantifies the probability that a 15-year-old girl will die of a maternal cause in her reproductive lifetime. Its intuitive appeal means it is a widely used summary measure for advocacy and international comparisons of maternal health. However, relative to mortality, women are at an even higher risk of experiencing life-threatening maternal morbidity called 'maternal near miss' (MNM) events-complications so severe that women almost die. As maternal mortality continues to decline, health indicators that include information on both fatal and non-fatal maternal outcomes are required.

METHODS

We propose a novel measure-the lifetime risk of MNM-to estimate the cumulative risk that a 15-year-old girl will experience a MNM in her reproductive lifetime, accounting for mortality between the ages 15 and 49 years. We apply the method to the case of Namibia (2019) using estimates of fertility and survival from the United Nations World Population Prospects along with nationally representative data on the MNM ratio.

RESULTS

We estimate a lifetime risk of MNM in Namibia in 2019 of between 1 in 40 and 1 in 35 when age-disaggregated MNM data are used, and 1 in 38 when a summary estimate for ages 15-49 years is used. This compares to a lifetime risk of maternal death of 1 in 142 and yields a lifetime risk of severe maternal outcome (MNM or death) of 1 in 30.

CONCLUSIONS

The lifetime risk of MNM is an urgently needed indicator of maternal morbidity because existing measures (the MNM ratio or rate) do not capture the cumulative risk over the reproductive life course, accounting for fertility and mortality levels.

Confidential Enquiry into Maternal Deaths in Namibia, 2018-2019: A Local Approach to Strengthen the Review Process and a Description of Review Findings and Recommendations

OBJECTIVES

First objective was to strengthen the national maternal death review, by addressing local challenges with each step of the review cycle. Second objective was to describe review findings and compare these with available findings of previous reviews.

METHODS

Confidential Enquiry into Maternal Deaths methodology was used to review maternal deaths. To improve reporting, the national committee focussed on addressing fear of blame among healthcare providers. Second focus was on dissemination of findings and acting on recommendations forthcoming the review. Reviewed were reported maternal deaths, that occurred between 1 April 2018 and 31 March 2019.

RESULTS

Seventy maternal deaths were reported; for 69 (98.6%) medical records were available, compared to 80/119 (67.2%) in 2012-2015. Reported maternal mortality ratio increased with 48% (92/100,000 live births compared to 62/100,000 in 2012-2015). Obstetric haemorrhage was leading cause of death in the past three reviews. The "no name, no blame" policy, aiming to identify health system failures, rather than mistakes of individuals, was repeatedly explained to healthcare providers during facility visits. Recommendations based on findings of the review, such as retaining experienced staff, continuous in-service training and guidance, were shared with decision makers at regional and national levels. Healthcare providers received training based on review findings, which resulted in improved management of similar cases.

CONCLUSIONS FOR PRACTICE

Enhanced implementation of Confidential Enquiry into Maternal Deaths was possible after addressing local challenges. Focussing on obtaining trust of healthcare providers and feeding back findings, resulted in better reporting and prevention of potential maternal deaths.

[Maternal morbidity and mortality in Brazil and the urgency of a national surveillance system for maternal near miss]

The World Health Organization (WHO) recommends the analysis of severe maternal morbidity/maternal near miss cases as complementary to the analysis of maternal deaths since the incidence is higher and the predictive factors of the two outcomes are similar. Considering that the reasons for maternal mortality in Brazil have remained constant despite the commitment made during the General Assembly of the United Nations in 2015, this article aims to propose a nationwide maternal near miss surveillance system. We propose the inclusion of maternal near miss events in the National List of Compulsory Notification of Diseases, Injuries, and Public Health Events, via the compatibility of the diagnostic criteria of maternal near miss, informed by the WHO, with the codes of the International Classification of Diseases for the identification of cases. Considering that health surveillance is based on several sources of information, notification could be made by health service professionals as soon as a confirmed or suspected case is identified. With the study of the factors associated with the outcomes, we expect a qualified evaluation of the services focused on obstetric care and consequent implementation of more efficient policies to prevent not only maternal death but also events that can both cause irreversible sequelae to women's health and increase the risk of fetal and neonatal death.

Prevalence and determinants of maternal near miss in Ethiopia: a systematic review and meta-analysis, 2015-2023

BACKGROUND

One of the most challenging problems in developing countries including Ethiopia is improving maternal health. About 303,000 mothers die globally, and one in every 180 is at risk from maternal causes. Developing regions account for 99% of maternal deaths. Maternal near miss (MNM) resulted in long-term consequences. A systematic review and meta-analysis was performed to assess the prevalence and predictors of maternal near miss in Ethiopia from January 2015 to March 2023.

METHODS

A systematic review and meta-analysis cover both published and unpublished studies from different databases (PubMed, CINHAL, Scopus, Science Direct, and the Cochrane Library) to search for published studies whilst searches for unpublished studies were conducted using Google Scholar and Google searches. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Duplicated studies were removed using Endnote X8. The paper quality was also assessed based on the JBI checklist. Finally, 21 studies were included in the study. Data synthesis and statistical analysis were conducted using STATA Version 17 software. Forest plots were used to present the pooled prevalence using the random effect model. Heterogeneity and publication bias was evaluated using Cochran's Q test, (Q) and I squared test (I²). Subgroup analysis based on study region and year of publication was performed.

RESULT

From a total of 705 obtained studies, twenty-one studies involving 701,997 pregnant or postpartum mothers were included in the final analysis. The national pooled prevalence of MNM in Ethiopia was 140/1000 [95% CI: 80, 190]. Lack of formal education [AOR = 2.10, 95% CI: 1.09, 3.10], Lack of antenatal care [AOR = 2.18, 95% CI: 1.33, 3.03], history of cesarean section [AOR = 4.07, 95% CI: 2.91, 5.24], anemia [AOR = 4.86, 95% CI: 3.24, 6.47], and having chronic medical disorder [AOR = 2.41, 95% CI: 1.53, 3.29] were among the predictors of maternal near misses from the pooled estimate.

CONCLUSION

The national prevalence of maternal near miss was still substantial. Antenatal care is found to be protective against maternal near miss. Emphasizing antenatal care to prevent anemia and modifying other chronic medical conditions is recommended as prevention strategies. Avoiding primary cesarean section is recommended unless a clear indication is present. Finally, the country should place more emphasis on strategies for reducing MNM and its consequences, with the hope of improving women's health.

Incidence and causes of severe maternal outcomes in Somaliland using the sub-Saharan Africa maternal near-miss criteria: A prospective cross-sectional study in a national referral hospital

OBJECTIVE

To describe the incidence and causes of severe maternal outcomes and the unmet need for life-saving obstetric interventions among women admitted for delivery in a referral hospital in Somaliland.

METHODS

A prospective cross-sectional study was conducted from April 15, 2019 to March 31, 2020, with women admitted during pregnancy or childbirth or within 42 days after delivery. Data were collected using the World Health Organization (WHO) and sub-Saharan Africa (SSA) maternal near-miss (MNM) tools. Descriptive analysis was performed by computing frequencies, proportions, and ratios.

RESULTS

The MNM ratios were 56 (SSA criteria) and 13 (WHO criteria) per 1000 live births. The mortality index was highest among women with medical complications (63%), followed by obstetric hemorrhage (13%), pregnancy-related infection (10%), and hypertensive disorders (7.9%) according to the SSA MNM criteria. Most women giving birth received prophylactic oxytocin for postpartum hemorrhage prevention (97%), and most laparotomies (60%) for ruptured uterus were conducted after 3 h.

CONCLUSION

There is a need to improve the quality of maternal health services through implementation of evidence-based obstetric interventions and continuous in-service training for healthcare providers. Using the SSA MNM criteria could facilitate such preventive measures in this setting as well as similar low-resource contexts.

Experiences of a dedicated Heart and Maternal Health Service providing multidisciplinary care to pregnant women with cardiac disease in a tertiary centre in Namibia

OBJECTIVES

First, to describe the implementation process, benefits and challenges of a multidisciplinary service for pregnant women with cardiac disease in Namibia. Second, to assess pregnancy outcomes in this population.

METHODS

In a tertiary hospital in Namibia, a multidisciplinary service was implemented by staff of obstetric and cardiology departments and included preconception counselling, provision of antenatal care and reliable contraception. Management guidelines developed for high-income settings were used, since no locally adapted guidelines were available. A cohort study was performed to assess cardiac, obstetric and fetal outcomes. Included were pregnant women with cardiac disease, referred to this service between 1 August 2016 and 31 July 2018.

RESULTS

Important benefits of this service were the integrated approach, improved access to reliable contraception and insight into drivers of poor outcome. Several challenges with use of available guidelines were encountered, as contextual factors specific to lower-income settings were not taken into consideration, such as higher rates of infection or barriers to access care. The cohort consisted of 65 women. Cardiac disease was diagnosed for the first time in 16 (24.6%) women, of whom 11 had pre-existing cardiac disease. These women presented more often with heart failure than women with known heart disease (75.0% vs. 6.1%, RR 12.5, 95% CI 3.9-38.0). Five women died. Cardiac events occurred in twenty-two women of whom eight developed thromboembolic events and two endocarditis. The majority had no indication for prophylaxis, based on available guidelines. Fetal events occurred in 36 pregnancies. After pregnancy more than half of women (35/65, 53.8%) were using long-acting reversible contraception.

CONCLUSIONS

Despite several barriers, it was possible to implement a multidisciplinary service in a high-burden setting. Cardiac and fetal event rates in this cohort were high. To improve outcomes the focus should be on availability of context-specific guidelines and better detection of cardiac disease.

The Prevalence and Risk Factors for Severe Maternal Morbidities: A Systematic Review and Meta-Analysis

Introduction

Maternal mortality and severe maternal morbidity remain major public health problems globally. Understanding their risk factors may result in better treatment solutions and preventive measures for maternal health. This review aims to identify the prevalence and risk factors of severe maternal morbidity (SMM) and maternal near miss (MNM).

Methods

A systematic review and meta-analysis was conducted to assess the prevalence and risk factors of SMM and MNM. The study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A systematic search was performed in the MEDLINE (PubMed), CINAHL (EBSCOhost), and Science Direct databases for articles published between 2011 and 2020.

Results

Twenty-four of the 44 studies included were assessed as being of good quality and having a low risk of bias. The prevalence of SMM and MNM was 2.45% (95% CI: 2.03, 2.88) and 1.68% (95% CI: 1.42, 1.95), respectively. The risk factors for SMM included history of cesarean section (OR [95% CI]: 1.63 [1.43, 1.87]), young maternal age (OR [95% CI]: 0.71 [0.60, 0.83]), singleton pregnancy (OR [95% CI]: 0.42 [0.32, 0.55]), vaginal delivery (OR [95% CI]: 0.11 [0.02, 0.47]), coexisting medical conditions (OR [95% CI]: 1.51 [1.28, 1.78]), and preterm gestation (OR [95% CI]: 0.14 [0.08, 0.23]). The sole risk factor for MNM was a history of cesarean section (OR [95% CI]: 2.68 [1.41, 5.10]).

Conclusions

Maternal age, coexisting medical conditions, history of abortion and cesarean delivery, gestational age, parity, and mode of delivery are associated with SMM and MNM. This helps us better understand the risk factors and their strength of association with SMM and MNM. Thus, initiatives such as educational programs, campaigns, and early detection of risk factors are recommended. Proper follow-up is important to monitor the progression of maternal health during the antenatal and postnatal periods.

Maternal and fetal outcomes of pregnancies complicated by acute hepatitis E and the impact of HIV status: A cross-sectional study in Namibia

BACKGROUND & AIMS

Namibia has been suffering from an outbreak of hepatitis E genotype 2 since 2017. As nearly half of hepatitis E-related deaths were among pregnant and postpartum women, we analysed maternal and fetal outcomes of pregnancies complicated by acute hepatitis E and assessed whether HIV-status impacted on outcome.

METHODS

A retrospective cross-sectional study was performed at Windhoek Hospital Complex. Pregnant and postpartum women, admitted between 13 October 2017 and 31 May 2019 with reactive IgM for Hepatitis E, were included. Outcomes were acute liver failure (ALF), maternal death, miscarriage, intra-uterine fetal death and neonatal death. Odds ratios (OR) and 95% confidence interval (CI) were calculated.

RESULTS

Seventy women were included. ALF occurred in 28 (40.0%) of whom 13 died amounting to a case fatality rate of 18.6%. Sixteen women (22.9%) were HIV infected, compared to 16.8% among the general pregnant population (OR 1.47, 95% CI 0.84-2.57, P = .17). ALF occurred in 4/5 (80%) HIV infected women not adherent to antiretroviral therapy compared to 1/8 (12.5%) women adherent to antiretroviral therapy (OR 28.0, 95% CI 1.4-580.6). There were 10 miscarriages (14.3%), five intra-uterine fetal deaths (7.1%) and four neonatal deaths (5.7%).

CONCLUSIONS

One in five pregnant women with Hepatitis E genotype 2 died, which is comparable to genotype 1 outbreaks. Despite small numbers, HIV infected women receiving antiretroviral therapy appear to be less likely to develop ALF in contrast with HIV infected women not on treatment. As there is currently no curative treatment, this phenomenon needs to be assessed in larger cohorts.

Women with maternal near-miss in the intensive care unit in Yangzhou, China: a 5-year retrospective study

BACKGROUND

Analysis of "maternal near-misses" is expected to facilitate assessment of the quality of maternity care in health facilities. Therefore, this study aimed to investigate incidence, risk factors and causes of maternal near-misses (MNM) admitted to the intensive care unit (ICU) within five years by using the World Health Organization's MNM approach.

METHODS

A five-year retrospective study was conducted in Subei People's Hospital of Yangzhou, Jiangsu Province from January 1, 2015 to December 31, 2019. Risk factors in 65 women with MNM in the intensive care unit (ICU) were explored by using chi-square tests and multivariable logistic regression analysis. Causes and interventions in MNM were investigated by descriptive analysis.

RESULTS

Average maternal near-miss incidence ratio (MNMIR) for ICU admission was 3.5 per 1000 live births. Average maternal mortality ratio (MMR) was 5 per 100,000 live births. MI for all MNM was 0.7%. Steady growth of MNMIR in ICU was witnessed in the five-year study period. Women who were referred from other hospitals (aOR 3.32; 95%CI 1.40-7.32) and had cesarean birth (aOR 4.96; 95%CI 1.66-14.86) were more likely to be admitted in ICU. Neonates born to women with MNM admitted in ICU had lower birthweight (aOR 5.41; 95%CI 2.53-11.58) and Apgar score at 5 min (aOR 6.39; 95%CI 2.20-18.55) compared with women with MNM outside ICU. ICU admission because of MNM occurred mostly postpartum (n = 63; 96.9%). Leading direct obstetric causes of MNM admitted in ICU were hypertensive diseases of pregnancy (n = 24; 36.9%), followed by postpartum hemorrhage (n = 14; 21.5%), while the leading indirect obstetric cause was heart diseases (n = 3; 4.6%).

CONCLUSIONS

Risk factors that were associated with MNM in ICU were referral and cesarean birth. Hypertensive disease of pregnancy and postpartum hemorrhage were the main obstetric causes of MNM in ICU. These findings would provide guidance to improve professional skills of primary health care providers and encourage vaginal birth in the absence of medical indications for cesarean birth.

Maternal mortality: near-miss events in middle-income countries, a systematic review

OBJECTIVE

To describe the incidence and main causes of maternal near-miss events in middle-income countries using the World Health Organization's (WHO) maternal near-miss tool and to evaluate its applicability in these settings.

METHODS

We did a systematic review of studies on maternal near misses in middle-income countries published over 2009-2020. We extracted data on number of live births, number of maternal near misses, major causes of maternal near miss and most frequent organ dysfunction. We extracted, or calculated, the maternal near-miss ratio, maternal mortality ratio and mortality index. We also noted descriptions of researchers' experiences and modifications of the WHO tool for local use.

FINDINGS

We included 69 studies from 26 countries (12 lower-middle- and 14 upper-middle-income countries). Studies reported a total of 50 552 maternal near misses out of 10 450 482 live births. Median number of cases of maternal near miss per 1000 live births was 15.9 (interquartile range, IQR: 8.9-34.7) in lower-middle- and 7.8 (IQR: 5.0-9.6) in upper-middle-income countries, with considerable variation between and within countries. The most frequent causes of near miss were obstetric haemorrhage in 19/40 studies in lower-middle-income countries and hypertensive disorders in 15/29 studies in upper-middle-income countries. Around half the studies recommended adaptations to the laboratory and management criteria to avoid underestimation of cases of near miss, as well as clearer guidance to avoid different interpretations of the tool.

CONCLUSION

In several countries, adaptations of the WHO near-miss tool to the local context were suggested, possibly hampering international comparisons, but facilitating locally relevant audits to learn lessons.

Great saves or near misses? Severe maternal outcome in Metro East, South Africa: A region-wide population-based case-control study

Objective

To assess the incidence of severe maternal outcome (SMO), comprising maternal mortality (MM) and maternal near miss (MNM), in Metro East health district, Western Cape Province, South Africa between November 2014 and November 2015 and to identify associated determinants leading to SMO with the aim to improve maternity care.

Methods

Region‐wide population‐based case‐control study. Women were included in the study, if they were maternal deaths or met MNM criteria, both as defined by WHO. Characteristics of women with SMO were compared with those of a sample of women without SMO, matched for age and parity, taken from midwifery‐led obstetrical units from two residential areas in Metro East, using multivariate regression analysis.

Results

Incidence of SMO was 9.1 per 1000 live births, and incidence of MNM was 8.6 per 1000 live births. Main causes of SMO were obstetrical hemorrhage and hypertensive disorders. Factors associated with SMO were HIV (adjusted odds ratio [aOR] 24.8; 95% confidence interval [CI] 10.0–61.6), pre‐eclampsia (aOR 17.5; 95% CI 7.9–38.7), birth by cesarean section (aOR 8.4; 95% CI 5.8–12.3), and chronic hypertension (aOR 2.4; 95% CI 1.1–5.1).

Conclusion

Evaluation of SMO incidence and associated determinants supports optimizing tailored guidelines in Metro‐East health district to improve maternal health.

Effects of antenatal care service utilization on maternal near miss in Gamo Gofa zone, southern Ethiopia: retrospective cohort study

Background

Antenatal care (ANC) provides an opportunity to prevent, identify and intervene maternal health problems. Maternal near miss (MNM), as an indicator of maternal health, is increasingly gaining global attention to measure these problems. However, little has been done to measure the effect of ANC on MNM in Ethiopia. Therefore, this study is aimed at determining the effect of ANC on MNM and its associated predictors at Gamo Gofa zone, southern Ethiopia.

Methods

Employing a retrospective cohort study design, 3 years data of 1440 pregnant mothers (480 ANC attendant and 960 non-attendant) were collected from all hospitals in the zone. Taking ANC visit as an exposure variable; we used a pretested checklist to extract relevant information from the study participants’ medical records. Characteristics of study participants, their ANC attendance status, MNM rates and associated predictors were determined.

Results

Twenty-five (5.2%) ANC attendant and seventy-one (7.4%) non-attendant mothers experienced MNM, (X² = 2,46, df = 2, p = 0.12). The incidence rates were 59.6 (95% CI: 40.6–88.2) and 86.1 (95%CI: 67.3–107.2)/1000 person-years for the ANC attendant and non-attendant mothers, respectively. Mothers who were living in rural areas had higher hazard ratio of experiencing MNM than those who were living in urban areas, with an adjusted hazard ratio (AHR) of 1.68 (95% CI, 1.01, 2.78).

Conclusion

ANC attendance tended to reduce MNM. However, late initiation and loss to follow-up were higher in the current study. Therefore, on time initiation and consistent utilization of ANC are required.
