ABSTRACT
Preterm birth remains an important global problem, and an important contributor to under-5 mortality. Reducing spontaneous preterm birth rates at the global level will require the early identification of patients at risk of preterm delivery in order to allow the initiation of appropriate prophylactic management strategies. Ideally these strategies target the underlying pathophysiologic causes of preterm labor. Prevention, however, becomes problematic as the causes of preterm birth are multifactorial and vary by gestational age, ethnicity, and social context. Unfortunately, current screening and diagnostic tests are non-specific, with only moderate clinical risk prediction, relying on the detection of downstream markers of the common end-stage pathway rather than identifying upstream pathway-specific pathophysiology that would help the provider initiate targeted interventions. As a result, the available management options (including cervical cerclage and vaginal progesterone) are used empirically with, at best, ambiguous results in clinical trials. Furthermore, the available screening tests have only modest clinical risk prediction, and fail to identify most patients who will have a preterm birth. Clearly defining preterm birth phenotypes and the biologic pathways leading to preterm birth is key to providing targeted, biomolecular pathway-specific interventions, ideally initiated in early pregnancy Pathway specific biomarker discovery, together with management strategies based on early, mid-, and-late trimester specific markers is integral to this process, which must be addressed in a systematic way through rigorously planned biomarker trials.
ABSTRACT
The global challenge of preterm birth persists with little or no progress being made to reduce its prevalence or mitigate its consequences, especially in low-resource settings where health systems are less well developed. Improved delivery of respectful person-centered care employing effective care models delivered by skilled healthcare professionals is essential for addressing these needs. These FIGO good practice recommendations provide an overview of the evidence regarding the effectiveness of the various care models for preventing and managing preterm birth across global contexts. We also highlight that continuity of care within existing, context-appropriate care models (such as midwifery-led care and group care), in primary as well as secondary care, is pivotal to delivering high quality care across the pregnancy continuum-prior to conception, through pregnancy and birth, and preparation for a subsequent pregnancy-to improve care to prevent and manage preterm birth.

Preterm birth remains the leading cause of mortality among under-5's and is a major contributor to the reduction in quality-of-life adjusted years and reduction in human capital. Globally, there are many interventions and care bundles that aim to reduce the impact of preterm birth once preterm labor has ensued and into the neonatal period; not all of these are applicable in all settings. Here, we introduce the FIGO PremPrep-5 initiative, which aims to disseminate key information on the most simple and effective interventions with the aim of increasing implementation globally. Before delivery, we recommend a course of antenatal corticosteroids, and intrapartum magnesium sulfate. At delivery, we recommend delayed cord clamping. Postnatally, we recommend early feeding with breast milk and immediate kangaroo care. While there are many other interventions that may improve outcomes at the time of labor and after preterm birth, these are clinically effective and relatively inexpensive options that can be practiced in most settings and supplemented with more advanced care. We include examples of a training video and infographics that will be used for dissemination.

Despite many advances in medicine we are still faced with emerging pathogens. Pregnant women have been disproportionately affected by previous coronavirus outbreaks. The COVID-19 pandemic has not affected pregnant women as greatly as SARS-CoV and MERS, but has posed other challenges such as the need for quarantine and isolation, limited access to antenatal care, use of personal protective equipment (PPE), vaccine hesitancy and inequities in vaccine access and therapeutics between rich countries and the global south. This review will describe the impact of the significant coronaviruses on pregnancy, with special focus on the challenges being encountered by the SARS-CoV-2 global pandemic.
ABSTRACT
BACKGROUND: Obstetric infections are the third most common cause of maternal mortality, with the largest burden in low and middle-income countries (LMICs). We analyzed causes of infection-related maternal deaths and near-miss identified contributing factors and generated suggested actions for quality of care improvement. METHOD: An international, virtual confidential enquiry was conducted for maternal deaths and near-miss cases that occurred in 15 health facilities in 11 LMICs reporting at least one death within the GLOSS study. Facility medical records and local review committee documents containing information on maternal characteristics, timing and chain of events, case management, outcomes, and facility characteristics were summarized into a case report for each woman and reviewed by an international external review committee. Modifiable factors were identified and suggested actions were organized using the three delays framework. RESULTS: Thirteen infection-related maternal deaths and 19 near-miss cases were reviewed in 20 virtual meetings by an international external review committee. Of 151 modifiable factors identified during the review, delays in receiving care contributed to 71/85 modifiable factors in maternal deaths and 55/66 modifiable factors in near-miss cases. Delays in reaching a GLOSS facility contributed to 5/85 and 1/66 modifiable factors for maternal deaths and near-miss cases, respectively. Two modifiable factors in maternal deaths were related to delays in the decision to seek care compared to three modifiable factors in near-miss cases. Suboptimal use of antibiotics, missing microbiological culture and other laboratory results, incorrect working diagnosis, and infrequent monitoring during admission were the main contributors to care delays among both maternal deaths and near-miss cases. Local facility audits were conducted for 2/13 maternal deaths and 0/19 near-miss cases. Based on the review findings, the external review committee recommended actions to improve the prevention and management of maternal infections. CONCLUSION: Prompt recognition and treatment of the infection remain critical addressable gaps in the provision of high-quality care to prevent and manage infection-related severe maternal outcomes in LMICs. Poor uptake of maternal death and near-miss reviews suggests missed learning opportunities by facility teams. Virtual platforms offer a feasible solution to improve routine adoption of confidential maternal death and near-miss reviews locally.

BACKGROUND: Globally, 11% of babies are born preterm each year. Preterm birth (PTB) is a leading cause of neonatal death and under-five mortality and morbidity, with lifelong sequelae in those who survive. PTB disproportionately impacts low/middle-income countries (LMICs) where the burden is highest. OBJECTIVES: This scoping review sought to the evidence for interventions that reduce the risk of PTB, focusing on the evidence from LMICs and describing how context is considered in evidence synthesis. DESIGN: We conducted a scoping review, to describe this wide topic area. We searched five electronic databases (2009-2020) and contacted experts to identify relevant systematic reviews of interventions to reduce the risk of PTB. We included published systematic reviews that examined the effectiveness of interventions and their effect on reducing the risk of PTB. Data were extracted and is described narratively. RESULTS: 139 published systematic reviews were included in the review. Interventions were categorised as primary or secondary. The interventions where the results showed a greater effect size and consistency across review findings included treatment of syphilis and vaginal candidiasis, vitamin D supplementation and cervical cerclage. Included in the 139 reviews were 1372 unique primary source studies. 28% primary studies were undertaken in LMIC contexts and only 4.5% undertaken in a low-income country (LIC) Only 10.8% of the reviews sought to explore the impact of context on findings, and 19.4% reviews did not report the settings or the primary studies. CONCLUSION: This scoping review highlights the lack of research evidence derived from contexts where the burden of PTB globally is greatest. The lack of rigour in addressing contextual applicability within systematic review methods is also highlighted. This presents a risk of inappropriate and unsafe recommendations for practice within these contexts. It also highlights a need for primary research, developing and testing interventions in LIC settings.

Despite policy on adolescent sexual and reproductive health (SRH) services and education, teen pregnancies remain common in South Africa. Social norms and cultural resistance are a well-documented challenge for SRH program implementation in South Africa, and beyond. To gain insight on the complex picture of adolescents' access to SRH information and services in a peri-urban township, we explored this topic from a diversity of perspectives, carrying out 86 interviews to capture perceptions of adolescents, their parents, community members, and health professionals. Our research shows that despite the taboo nature of the issue of adolescent SRH, individual positions on adolescent access to SRH services and information are shifting and diverse, and are influenced by factors other than cultural norms. This research serves as a reminder to avoid simplistic reference to "culture" as a way of explaining health-related behaviors and people's responses to health challenges.

OBJECTIVE: To assess feasibility and acceptability of a novel, low-cost "Suction Tube Uterine Tamponade" (STUT) treatment for refractory postpartum hemorrhage (PPH). METHODS: We allocated patients with refractory PPH by randomly ordered envelopes to STUT or routine uterine balloon tamponade (UBT, Ellavi free-flow system) in 10 hospitals in South Africa. In the STUT group, a 24FG Levin stomach tube was inserted into the uterine cavity and vacuum created with a vacuum pump or manual vacuum aspiration syringe. RESULTS: For this internal pilot study, 12 participants were allocated to STUT and 12 to UBT. Insertion failed in one of each group and was recorded as difficult in 3/10 STUT and 4/9 UBT insertions respectively (five missing data). There were two laparotomies and one intensive care unit admission in the UBT group. Pain during STUT insertion was graded as none/mild in 9/10 and severe in 1/10. The experience of the STUT procedure was graded as fine in 4/11 and "uncomfortable but acceptable" in 7/11. CONCLUSION: STUT is feasible and acceptable, justifying continuation of our trial. These data will also inform a large World Health Organization trial to test effectiveness of uterine tamponade methods. The numbers are too small to support any clinical recommendation.

OBJECTIVE: To describe global geographic variations in the diagnosis and management of placenta accreta spectrum (PAS). METHODS: An international cross-sectional study was conducted among PAS experts practicing at medical institutions in member states of the United Nations. Survey questions focused on diagnostic evaluation and management strategies for PAS. RESULTS: A total of 134 centers participated. Participating centers represented each of the United Nations' designated regions. Of those, 118 (88%) reported practicing in a medium-volume or high-volume center. First-trimester PAS screen was reported in 35 (26.1%) centers. Respondents consistently implement guideline-supported care practices, including utilization of ultrasound as the primary diagnostic modality (134, 100%) and implementation of multidisciplinary care teams (115, 85.8%). Less than 10% of respondents reported routinely managing PAS without hysterectomy; these centers were predominantly located in Europe and Africa. Antepartum management and availability of mental health support for PAS patients varied widely. CONCLUSION: Worldwide, there is a strong adherence to PAS care guidelines; however, regional variations do exist. Comparing variations in care to outcomes will provide insight into the clinically significant practice variability.

AbstractProgress in adolescent sexual and reproductive health (SRH) remains unequal: adolescent pregnancies are more likely to occur in marginalised communities, or in very poor households. This study aimed to comprehend from adolescents' own perspectives, the circumstances of falling pregnant and coping with motherhood in informal settlements in South Africa, to better understand the SRH challenges adolescents in these settings may face. A qualitative study was carried out over a two-month period in 2019 to analyse the perceptions held by adolescents in informal settlements served by four community-level clinics in the adjacent township. We found that adolescents face overlapping barriers in seeking to avoid unintended pregnancy in informal settlements. Once they become mothers, their trajectory is limited by the resources and support available from their own parents, particularly their mothers, and to a lesser extent, their partners. We draw on the concept of agency to examine their accounts and to highlight the importance of addressing broader contextual constraints.

OBJECTIVE: To describe risk factors and outcomes of pregnant women infected with SARS-CoV-2 admitted to South African healthcare facilities. METHODS: A population-based cohort study was conducted utilizing an amended International Obstetric Surveillance System protocol. Data on pregnant women with SARS-CoV-2 infection, hospitalized between April 14, 2020, and November 24, 2020, were analyzed. RESULTS: A total of 36 hospitals submitted data on 673 infected hospitalized pregnant women; 217 (32.2%) were admitted for COVID-19 illness and 456 for other indications. There were 39 deaths with a case fatality rate of 6.3%: 32 (14.7%) deaths occurred in women admitted for COVID-19 illness compared to 7 (1.8%) in women admitted for other indications. Of the women, 106 (15.9%) required critical care. Maternal tuberculosis, but not HIV co-infection or other co-morbidities, was associated with admission for COVID-19 illness. Rates of cesarean delivery did not differ significantly between women admitted for COVID-19 and those admitted for other indications. There were 179 (35.4%) preterm births, 25 (4.7%) stillbirths, 12 (2.3%) neonatal deaths, and 162 (30.8%) neonatal admissions. Neonatal outcomes did not differ significantly from those of infected women admitted for other indications. CONCLUSION: The maternal mortality rate was high among women admitted with SARS-CoV-2 infection and higher in women admitted primarily for COVID-19 illness with tuberculosis being the only co-morbidity associated with admission.

Global response to COVID-19 pandemic has inadvertently undermined the achievement of existing public health priorities and laregely overlooked local context. Recent evidence suggests that this will cause additional maternal and childhood mortality and morbidity especially in low- and middle-income countries (LMICs). Here we have explored the contextual factors influencing maternal, neonatal and children health (MNCH) care in Bangladesh, Nigeria and South Africa amidst the pandemic. Our findings suggest that between March and May 2020, there was a reduction in utilisation of basic essential MNCH services such as antenatal care, family planning and immunization due to: a) the implementation of lockdown which triggered fear of contracting the COVID-19 and deterred people from accessing basic MNCH care, and b) a shift of focus towards pandemic, causing the detriment to other health services, and c) resource constraints. Taken together these issues have resulted in compromised provision of basic general healthcare. Given the likelihood of recurrent waves of the pandemic globally, COVID-19 mitigation plans therefore should be integrated with standard care provision to enhance system resilience to cope with all health needs. This commentary suggests a four-point contextualised mitigation plan to safeguard MNCH care during the pandemic using the observed countries as exemplars for LMIC health system adaptations to maintain the trajectory of progress regarding sustainable development goals (SDGs).

BACKGROUND: Late maternal mortality (up-to 1-year postpartum) is poorly reported globally and is commonly due to cardiovascular disease (CVD). We investigated targeted interventions aiming at reducing peripartum heart failure admission and late maternal death. METHODS AND RESULTS: Prospective single-centre study of 269 peripartum women presenting with CVD in pregnancy, or within 6-months postpartum. Both cardiac disease maternity (CDM) Group-I and Group-II were treated by a dedicated cardiac-obstetric team. CDM Group-II received additional interventions: 1. Early (2-6â¯weeks) postpartum follow-up at the CDM clinic and immediate referral to dedicated CVD specialist clinics. 2. Beta-blocker therapy was continued in women with LVEF<45% while pregnant, or immediately started postpartum. Of 269 consecutive women (mean age 28.6⯱â¯5.9), 213 presented prepartum, 22% in NYHA groups III-IV and 79% in modified WHO groups III-IV. Patients were diagnosed with congenital heart disease (30%), valvular heart disease (25%) and cardiomyopathy (31%). The groups were similar in age, diagnosis, NYHA, modified WHO, BP and HIV, but Group-II had a higher rate of previously known CVD (pâ¯<â¯0.001) and a lower rate of being nulliparous (pâ¯<â¯0.0005). Of Group-I patients 9 died within the 12-month follow-up period versus one death in Group-II (pâ¯=â¯0.047). Heart failure leading to admission was 32% in Group-I versus 14% in Group-II (pâ¯=â¯0.0008), with Group-II having a higher beta-blocker use peripartum (pâ¯=â¯0.009). Perinatal mortality rate was 22/1000 live births with no differences between groups. CONCLUSION: Early follow-up in a dedicated CDM clinic with targeted pharmacological interventions led to a significant reduction in peripartum heart failure admission and mortality.

Pregnancy, viewed as a stress test of the haemodynamic system, may unmask underlying cardiac disease. Pregnancy may also induce de novo cardiac disease. N-terminal pro brain-type natriuretic peptide (NT-proBNP) is a useful biomarker in all clinical conditions in which the ventricle is stressed and especially stretched in the general population. In hypertensive diseases of pregnancy, increased levels of NT-proBNP in preeclampsia are associated with increased cardiac filling pressures and diastolic dysfunction. Increased levels of NT-proBNP in pregnant women with known cardiac disease may lead to earlier diagnosis of impending heart failure. Similarly, elevated levels of NT-proBNP assist with the diagnosis of peripartum cardiomyopathy and are increasingly used in follow-up. Women with known congenital heart disease who are pregnant can be screened for risk of cardiac events such as heart failure by the use of NT-proBNP levels. There is a paucity of data in pregnancy with the use of NT-proBNP and more research is needed.
ABSTRACT
OBJECTIVES: To evaluate quality of life (QoL) parameters among women categorized with a maternal near-miss during pregnancy. METHODS: The present prospective cohort study was conducted at a tertiary referral hospital in South Africa between April 1, 2013, and March 31, 2016. Patients who experienced maternal near-miss events were included and patients with uncomplicated low-risk pregnancies were enrolled as a control group. Various parameters were assessed using a WHO QoL questionnaire. RESULTS: The maternal near-miss and uncomplicated low-risk pregnancy (control) groups comprised 95 and 51 women. The maternal near-miss group scored lower than the control group in all four domains of the questionnaire (P<0.001). Overall, 42 (82%) women in the control group and 41 (43%) women in the maternal near-miss group desired future fertility (P<0.001). Women in the maternal near-miss group who had experienced perinatal loss scored lower in the physical health and well-being (P=0.009), psychological health and well-being (P=0.007), and environment (P=0.031) domains compared with women in the maternal near-miss group who experienced a live delivery. Nonetheless, QoL scores among women in the maternal near-miss group who had experienced perinatal loss remained lower than those reported by women in the control group (P<0.001). CONCLUSION: A maternal near-miss event during pregnancy was associated with reduced QoL, especially among women who had experienced perinatal loss.

Physiological changes occur in pregnancy to nurture the developing foetus and prepare the mother for labour and delivery. Some of these changes influence normal biochemical values while others may mimic symptoms of medical disease. It is important to differentiate between normal physiological changes and disease pathology. This review highlights the important changes that take place during normal pregnancy.

AIMS: Cardiac disease is emerging as an important contributor to maternal deaths in both lower-to-middle and higherincome countries. There has been a steady increase in the overall institutional maternal mortality rate in South Africa over the last decade. The objectives of this study were to determine the cardiovascular causes and contributing factors of maternal death in South Africa, and identify avoidable factors, and thus improve the quality of care provided. METHODS: Data collected via the South African National Confidential Enquiry into Maternal Deaths (NCCEMD) for the period 2011-2013 for cardiovascular disease (CVD) reported as the primary pathology was analysed. Only data for maternal deaths within 42 days post-delivery were recorded, as per statutory requirement. One hundred and sixty-nine cases were reported for this period, with 118 complete hospital case files available for assessment and data analysis. RESULTS: Peripartum cardiomyopathy (PPCM) (34%) and complications of rheumatic heart disease (RHD) (25.3%) were the most important causes of maternal death. Hypertensive disorders of pregnancy, HIV disease infection and anaemia were important contributing factors identified in women who died of peripartum cardiomyopathy. Mitral stenosis was the most important contributor to death in RHD cases. Of children born alive, 71.8% were born preterm and 64.5% had low birth weight. Seventy-eight per cent of patients received antenatal care, however only 33.7% had a specialist as an antenatal care provider. Avoidable factors contributing to death included delay in patients seeking help (41.5%), lack of expertise of medical staff managing the case (29.7%), delay in referral to the appropriate level of care (26.3%), and delay in appropriate action (36.4%). CONCLUSION: The pattern of CVD contributing to maternal death in South Africa was dominated by PPCM and complications of RHD, which could, to a large extent, have been avoided. It is likely that there were many CVD deaths that were not reported, such as late maternal mortality (up to one year postpartum). Infrastructural changes, use of appropriate referral algorithm and training of primary, secondary and tertiary staff in CVD complicating pregnancy is likely to improve the outcome. The use of simple screening equipment and point-of-care testing for early-onset heart failure should be explored via research projects.

BACKGROUND: In order to reduce maternal mortality in South Africa (SA), it is important to understand the process of obstetric care, identify weaknesses within the system, and implement interventions for improving care. OBJECTIVE: To determine the spectrum of maternal morbidity and mortality in the Pretoria Academic Complex (PAC), SA. METHODS: A descriptive population-based study that included all women delivering in the PAC. The World Health Organization definition, criteria and indicators of near miss and maternal death were used to identify women with severe complications in pregnancy. RESULTS: Between 1 August 2013 and 31 July 2014, there were 26,614 deliveries in the PAC. The institutional maternal mortality ratio was 71.4/100,000 live births. The HIV infection rate was 19.9%, and 2.7% of women had unknown HIV status. Of the women, 1120 (4.2%) developed potentially life-threatening conditions and 136 (0.5%) life-threatening conditions. The mortality index was 14.0% overall, 30.0% for non-pregnancy-related infections, 2.0% for obstetric haemorrhage and 13.6% for hypertension. Of the women with life-threatening conditions, 39.3% were referred from the primary level of care. Vascular, uterine and coagulation dysfunctions were the most frequent organ dysfunctions in women with life-threatening conditions. The perinatal mortality rate was 26.9/1000 births overall, 23.1/1000 for women with non-life-threatening conditions, and 198.0/1000 for women with life-threatening conditions. CONCLUSION: About one in 20 pregnant women in the PAC had a potentially life-threatening condition; 39.3% of women presented to a primary level facility as an acute emergency and had to be transferred for tertiary care. All healthcare professionals involved in maternity care must have knowledge and skills that equip them to manage obstetric emergencies. Review of the basic antenatal care protocol may be necessary.
ABSTRACT
OBJECTIVE: No randomized controlled trial has compared vaginal progesterone and cervical cerclage directly for the prevention of preterm birth in women with a sonographic short cervix in the mid trimester, singleton gestation, and previous spontaneous preterm birth. We performed an indirect comparison of vaginal progesterone vs cerclage using placebo/no cerclage as the common comparator. STUDY DESIGN: Adjusted indirect metaanalysis of randomized controlled trials. RESULTS: Four studies that evaluated vaginal progesterone vs placebo (158 patients) and 5 studies that evaluated cerclage vs no cerclage (504 patients) were included. Both interventions were associated with a statistically significant reduction in the risk of preterm birth at <32 weeks of gestation and composite perinatal morbidity and mortality compared with placebo/no cerclage. Adjusted indirect metaanalyses did not show statistically significant differences between vaginal progesterone and cerclage in the reduction of preterm birth or adverse perinatal outcomes. CONCLUSION: Based on state-of-the-art methods for indirect comparisons, either vaginal progesterone or cerclage are equally efficacious in the prevention of preterm birth in women with a sonographic short cervix in the mid trimester, singleton gestation, and previous preterm birth. Selection of the optimal treatment needs to consider adverse events, cost and patient/clinician preferences.

OBJECTIVE: To determine whether the use of vaginal progesterone in asymptomatic women with a sonographic short cervix (≤ 25 mm) in the midtrimester reduces the risk of preterm birth and improves neonatal morbidity and mortality. STUDY DESIGN: Individual patient data metaanalysis of randomized controlled trials. RESULTS: Five trials of high quality were included with a total of 775 women and 827 infants. Treatment with vaginal progesterone was associated with a significant reduction in the rate of preterm birth <33 weeks (relative risk [RR], 0.58; 95% confidence interval [CI], 0.42-0.80), <35 weeks (RR, 0.69; 95% CI, 0.55-0.88), and <28 weeks (RR, 0.50; 95% CI, 0.30-0.81); respiratory distress syndrome (RR, 0.48; 95% CI, 0.30-0.76); composite neonatal morbidity and mortality (RR, 0.57; 95% CI, 0.40-0.81); birthweight <1500 g (RR, 0.55; 95% CI, 0.38-0.80); admission to neonatal intensive care unit (RR, 0.75; 95% CI, 0.59-0.94); and requirement for mechanical ventilation (RR, 0.66; 95% CI, 0.44-0.98). There were no significant differences between the vaginal progesterone and placebo groups in the rate of adverse maternal events or congenital anomalies. CONCLUSION: Vaginal progesterone administration to asymptomatic women with a sonographic short cervix reduces the risk of preterm birth and neonatal morbidity and mortality.
