The effectiveness of the Congo Red Dot paper test in hypertensive disorders of pregnancy: A systematic review and meta-analysis.

Background: Congo Red Dot Paper Test (CRDPT) appears to be a simple, cost-effective, non-invasive diagnostic tool for hypertensive disorders of pregnancy (HDP). The main objective of the study is to assess the effectiveness of CRDPT in detecting HDP. Methods: This is a systemic review and meta-analysis of published studies on the effectiveness of CRDPT in the detection of HDP. The study was conducted in line with the PRISMA-DTA guidelines. The PICOS framework was used to search for relevant articles using Medline, PubMed, Google Scholar, Web of Science, and the Cochrane Library databases. The articles were screened against a set of inclusion and exclusion criteria and analysed using the Review Manager 5.4 software. Results: A title, abstract and full article screening was conducted on 18,153 potential articles based on the inclusion and exclusion criteria. The screening yielded five articles for meta-analysis. The total number of normotensive pregnant women (n = 3,380) in the included studies was five times higher than the total number of women with pre-eclampsia (n = 535). A difference between the HDP and normotensive group was noted. This is indicated by a significantly decreased in the effectiveness of CRDPT in detecting HDP as compared to normotensive group [Risk Ratio (RR) = 6.32 (2.17, 18.43) p < 0.00001]. The included studies had a high nature of heterogeneity (I 2 = 98%, p < 0.00001) partially due to different study designs included in the analysis and different regions where studies were conducted given that none of these studies were conducted in African countries where HDP is prominent. Conclusions: According to results generated from 5 studies in this meta-analysis, it was found that CRDPT might not be effective in the detection of hypertensive disorder of pregnancy. Moreover, more research, especially in African women where hypertensive disorders of pregnancy are prevalent, are re-quired to ascertain these findings.

Population-level impact of beliefs and attitudes on vaccine decision-making in South Africa: results from the COVID-19 Vaccine Survey (2021/2022).

OBJECTIVES: In addition to being home to more than seven million HIV-infected individuals, South Africa also has a high burden of COVID-19 and related comorbidities worldwide. We aimed to identify the most influential "beliefs" and "attitudes" on vaccine decision-making behavior. STUDY DESIGN: This study used panel data from cross-sectional surveys. METHODS: We used the data from Black South Africans who participated in the "COVID-19 Vaccine Surveys" (November 2021 and February/March 2022) in South Africa. Besides standard risk factor analysis, such as multivariable logistic regression models, we also used the modified version of population attributable risk percent and estimated the population-level impacts of beliefs and attitudes on vaccine decision-making behavior using the methodology in multifactorial setting. RESULTS: A total of 1399 people (57% men and 43% women) who participated in both surveys were analyzed. Of these, 336 (24%) reported being vaccinated in survey 2. Overall low perceived risk, concerns around efficacy, and safety were identified as the most influential factors and associated with 52%-72% (<40 years) and 34%-55% (40+ years) of the unvaccinated individuals. CONCLUSION: Our findings highlighted the most influential beliefs and attitudes on vaccine decision-making and their population-level impacts, which are likely to have significant public health implications exclusively for this population.

Expectant management of advanced abdominal pregnancies: Is it justifiable?

OBJECTIVE: To evaluate the outcome of a case series of women with advanced abdominal pregnancies (AAP) who underwent expectant management. STUDY DESIGN: A retrospective study that utilized prospective data of 46 women who were admitted for expectant management at a tertiary hospital in Durban, South Africa. All data was analyzed descriptively and presented in percentages. RESULTS: The average period of expectant management was 27 days; thirty-three (72 %) of the 46 women were discharged from the hospital with live babies. There were 11 (24 %) neonatal deaths and two cases of stillbirths. There were no maternal deaths and morbidity was minimal. CONCLUSION: When diagnosed after the 24th week of gestation, an option is expectant management which includes careful patient selection, prolonged hospitalization, and close antenatal fetal and maternal surveillance to achieve fetal viability. Management by experienced clinicians and a multidisciplinary team in a tertiary institution is recommended. Informed consent needs to take into consideration the risks with interventional laparotomy, social separation from family and friends, and the guarded perinatal outcome.

Persistent maternal tachycardia: A clinical alert for healthcare professionals providing maternity care in South Africa.

Cardiac disease is one of the commonest causes of indirect maternal deaths globally. This brief report is a reminder that isolated maternal tachycardia at rest is a clinical alert and warrants a detailed history in relation to cardiac disorders, thorough clinical examination of all organ systems, relevant investigations such as imaging, and expert advice to avoid serious adverse events. We reflect on a belatedly investigated persistent maternal tachycardia resulting in a fatal postpartum collapse due to mitral stenosis. The lost window of opportunity for appropriate investigation and management of the tachycardia provides an insight into many similar maternal deaths in South Africa. Key clinical messages regarding persistent maternal tachycardia are presented for midwives and doctors caring for pregnant women.

Colorectal surgical outcomes following implementation of an enhanced recovery after surgery programme in Cape Town.

BACKGROUND: Colorectal surgery is commonly performed for benign and malignant colorectal disease. The aim of this study was to describe length of stay (LOS), complications and its associated factors in patients undergoing elective colorectal surgery following implementation of an enhanced recovery after surgery (ERAS) programme in South Africa (SA). METHODS: Socio-demographic, pre- intra- and postoperative clinical details and compliance to the ERAS guidelines were recorded in all patients undergoing colorectal surgery in a private practice in Cape Town, SA. Means and standard deviations or medians and interquartile range (IQR), as appropriate, were used to describe continuous variables and frequencies and percentages for categorical variables. Bivariate and multivariate analyses using linear regression of log transformed LOS and logistic regression for development of complications were performed. RESULTS: Between 2015 and 2019, 457 patients had elective colorectal surgical procedures. The median LOS was 5 days (IQR 3-7). Pre- and intraoperative compliance was 92% and 86% respectively. In total, 203 (44%) patients developed 346 complications, of which 61% were minor. On bivariate analysis, increased intraoperative compliance was associated with a significant decrease in LOS (coefficient [ß] = 0.987, 95% confidence interval [CI] 0.984-0.991) and complications (odds ratio [OR] 0.457, 95/5 CI 0.266-0.787). For every additional 30 minutes of theatre time, irrespective of type of procedure, LOS increased by 8% and complications by 12%. On multivariate analysis, laparoscopic compared to open surgery was also associated with a shorter LOS (exp [ß] = 0.667, 95% CI 0.580-0.767 p < 0.001) and reduced complications (OR 0.457, 95% CI 0.266-0.787). CONCLUSION: Our results show that high compliance to the ERAS guidelines is possible in the private sector in SA and that a significant reduction in LOS can be achieved without placing the patient at a higher risk of complications.

An imperative to offer pregnant and lactating women access to the COVID-19 vaccination roll-out programme.

In view of the continuing worldwide spread of COVID-19 infection, the increased morbidity and mortality from the disease during pregnancy, and the current efficacy and safety of vaccines in non-pregnant individuals, vaccines should not be withheld from women simply because of pregnancy or lactation. All pregnant women, especially healthcare professionals, should be offered vaccination and counselled about its advantages and disadvantages by their maternity care providers. Complete eradication of COVID-19 infection will be possible if potential niduses of the infection, which may act as sources for future outbreaks, are protected against the pathogen. However, if a hypothetical medication is the only means yet proven of limiting severe compromise to maternal health, access to the medication should be at the pregnant woman's discretion. Shared decision-making requires physicians to actively engage with their patients and share their knowledge about the subject matter.

Aminopeptidase A (ENPEP) gene polymorphisms and preeclampsia: Descriptive analysis.

OBJECTIVE: The etiology of preeclampsia (PE) remains elusive. Recent genome-wide association studies have identified a number of genetic variants associated with blood pressure variations in east Asians. One of the genetic variants is the aminopeptidase A (ENPEP) gene, which converts angiotensin II to angiotensin III. The C allele of rs6825911 is a risk for hypertension. The current study investigated whether genetic variants of ENPEP play a role in the pathogenesis of preeclampsia. STUDY DESIGN: The study was a descriptive analysis of gene polymorphisms of ENPEP; 602 pregnant women of African ancestry [normotensive (n = 245) and PE (n = 357)] were recruited. The two groups were divided according to their HIV status. The PE group consisted of early- and late-onset sub-categories. A single nucleotide polymorphism of rs6825911 was analyzed using the TaqMan® Probe mix and by means of real time polymerase chain reaction. RESULTS: The risk of C allele for PE was 1.07 (95 % CI 0.83-1.38, P = 0.589) for allele comparison and the risk for preeclampsia CC to CT/TT was 1.33 (95 % CI 0.96-1.85, P = 0.086). The sub analysis for the PE group without HIV infection the risk of C allele was 1.25 (95 % CI 0.838-1.78, P = 0.199) and the risk of PE of CC to CT/TT was 1.51 (95 %CI: 0.96-2.35, P = 0.071). CONCLUSION: This is the first study in a homogenous South African population of African ancestry to show that the variant of ENPEP gene does not play a role in pathogenesis of preeclampsia.

Aspirin in the prevention of preeclampsia: A protocol for systematic review and meta analysis.

INTRODUCTION: Aspirin is widely used to prevent pregnancy related vascular disorders such as preeclampsia (PE), intrauterine growth restriction and maternal disorders. However, the indications for the use of aspirin during pregnancy is currently controversial because the dosage of aspirin used and the sample sizes in various studies differ considerably. Furthermore, women of African ancestry are more likely to have higher rates of PE and more severe cases than those of their Caucasian counterparts. Yet, there are very few studies in this population group. Therefore, the aim of this review will be to determine the effect of low-dose aspirin (LDA) for prevention of PE in women of African ancestry. METHODS AND ANALYSIS: This is a protocol for a systematic review and meta-analysis of published studies on the effect of LDA for prevention of PE. Relevant information will be accessed from the following databases; PubMed, Cochrane Central Register of Controlled Trials, Google Scholar, Google, EBSCO Host, and the Web of Science. The studies will be mapped in 2 stages: stage 1 will map studies descriptively by focus and method; stage 2 will involve additional inclusion criteria, quality assessment and data extraction undertaken by 2 reviewers in parallel. Evidence will be synthesized using relevant systematic research tools. Meta-analysis and subgroup analysis will be conducted using RevMan whilst Stata 13 will be used for meta-regressions. We will follow recommendations described in the preferred reporting items for systematic reviews and meta-analyses statement and the Cochrane Handbook for Intervention Reviews. DISCUSSION: The use of LDA as a prophylactic treatment has been considered for the prevention of PE. However, studies evaluating the use of LDA in women of African ancestry are few. Therefore, with the increase in the prevalence of PE in the African population, it is critical to further investigate the use of LDA in pregnant women of African ancestry. ETHICS AND DISSEMINATION: The review and meta-analysis will not require ethical approval and the findings will be published in peer-reviewed journals and presented at local and international conferences. The findings of this review will inform all stakeholders on current and future guidelines on the use of aspirin in pregnancy, especially in populations of African ancestry.

Mapping awareness of breast and cervical cancer risk factors, symptoms and lay beliefs in Uganda and South Africa.

BACKGROUND: Breast and cervical cancer are leading causes of cancer burden in Sub-Saharan Africa (SSA). We measured breast and cervical cancer symptom and risk factor awareness and lay beliefs in Uganda and South Africa (SA). METHODS: Between August and December 2018 we conducted a cross-sectional survey of women ≥18 years in one urban and one rural site per country. Households were selected using systematic random sampling, then one woman per household randomly selected to participate. Data were collected by interviewers using electronic tablets customised with the locally validated African Women Awareness of Cancer (AWACAN) tool. This has unprompted questions (testing recall) followed by prompted questions (testing recognition) on risk factor, symptom awareness and lay beliefs for breast and cervical cancer. Mann Whitney and Kruskal Wallis tests were used to compare the association between socio-demographic variables and outcomes. Poisson regression with robust variance was conducted to identify independent socio-demographic predictors. RESULTS: Of the 1758 women interviewed, 90.8% had heard of breast and 89.4% of cervical cancer. 8.7% recalled at least one breast risk factor and 38.1% recalled at least one cervical cancer risk factor. 78.0% and 57.7% recalled at least one breast/cervical cancer symptom respectively. Recognition of risk factors and symptoms was higher than recall. Many women were unaware that HPV, HIV, and not being screened were cervical cancer risk factors (23.7%, 46.8%, 26.5% respectively). In SA, urban compared to rural women had significantly higher symptom and risk factor awareness for both cancers. In Uganda married women/living with a partner had higher awareness of breast cancer risk factors and cervical cancer symptoms compared to women not living with a partner. Women mentioned several lay beliefs (e.g. putting money in their bra as a breast cancer risk factor). CONCLUSION: We identified gaps in breast and cervical cancer symptom and risk factor awareness. Our results provide direction for locally targeted cancer awareness intervention programs and serve as a baseline measure against which to evaluate interventions in SSA.

The impact of the duration of HAART on cytokine profiles in pregnancy.

OBJECTIVE: To determine the cytokine profile of HIV infected women treated with highly active anti-retroviral therapy (HAART) of variable duration in pregnancy. METHODS: HIV infected women were enrolled at a large tertiary hospital in Durban, South Africa in their antenatal period and stratified into those that initiated HAART before pregnancy (pre-pregnancy HAART or PPH group) and those who initiated HAART during pregnancy (in-pregnancy HAART or IPH group). These were compared with HIV negative women (HN group), matched for gestational age at the time of enrolment. Serum was obtained and Th1 and Th2 cytokines expression determined using the Bio-Plex Pro™ Human Cytokine Treg Panels. RESULTS: The overall cytokine profile of the cohort was pro-inflammatory as a result of significant IL-6 and TNF alpha expression. The anti-inflammatory markers (i.e. Th2 cytokines, namely IL4 and IL10) were poorly expressed by the whole cohort, with IL 4 seen almost exclusively in the IPH group, thus counter-balancing the predominantly pro-inflammatory milieu only in this group. PPH group had a pro-inflammatory milieu comparable to the HN control. IL 6 was the predominant cytokine in all groups, and as expected, it increased with advancing gestation in all the groups. This highly pro-inflammatory milieu was unexpected and needs further review CONCLUSION: Long use of HAART suppresses the anti-inflammatory markers previously reported to be conducive for the wellbeing of pregnancy. This effect needs further review as it was similarly observed in our HIV uninfected controls.

The impact of circulating exosomes derived from early and late onset pre-eclamptic pregnancies on inflammatory cytokine secretion by BeWo cells.

OBJECTIVES: The pathogenesis of pre-eclampsia (PE) is associated with significant maternal and neonatal complications, an increased inflammatory response, placental hypoxia, and endothelial dysfunction, coupled with differential exosomal release profiles with immune modulation effects. Hence, this study evaluated the impact of circulating exosomes derived from early and late-onset pre-eclamptic pregnancies on inflammatory cytokine secretion by BeWo cells. STUDY DESIGN: Exosomes were isolated from plasma obtained from early-onset pre-eclamptic (EOPE; n = 15), late-onset pre-eclamptic (LOPE; n = 15), and gestational age-matched normotensive pregnancies (N ≤ 33 weeks; n = 15 and N ≥ 34 weeks; n = 15). Human BeWo cells were treated with characterized and quantified exosomes (100 µg/mL exosomal protein per pregnant group) for 24 h. The immunoassay method was used to measure the concentration of IL-8, IL-10, leptin, and HIF-α. RESULTS: Exosome administration from women with EOPE and LOPE increased IL-8 and decreased IL-10 expression in BeWo cells. CONCLUSION: Cumulatively, our data demonstrated that circulating exosomes from the placenta and activated immune cells potentially influence inflammatory cytokine production in pre-eclamptic pregnancies.

Effects of emergency obstetric care training on maternal and perinatal outcomes: a stepped wedge cluster randomised trial in South Africa.

INTRODUCTION: Two-thirds of maternal deaths and 40% of intrapartum-related neonatal deaths are thought to be preventable through emergency obstetric and newborn care (EmOC&NC). The effectiveness of 'skills and drills' training of maternity staff in EmOC&NC was evaluated. METHODS: Implementation research using a stepped wedge cluster randomised trial including 127 of 129 healthcare facilities (HCFs) across the 11 districts in South Africa with the highest maternal mortality. The sequence in which all districts received EmOC&NC training was randomised but could not be blinded. The timing of training resulted in 10 districts providing data before and 10 providing data after EmOC&NC training. Primary outcome measures derived for HCFs are as follows: stillbirth rate (SBR), early neonatal death (ENND) rate, institutional maternal mortality ratio (iMMR) and direct obstetric case fatality rate (CFR), number of complications recognised and managed and CFR by complication. RESULTS: At baseline, median SBR (per 1000 births) and ENND rate (per 1000 live births) were 9 (IQR 0-28) and 0 (IQR 0-9). No significant changes following training in EmOC&NC were detected for any of the stated outcomes: SBR (adjusted incidence rate ratio (aIRR) 0.97, 95% CI 0.91 to 1.05), iMMR (aIRR 1.23, 95% CI 0.80 to 1.90), ENND rate (aIRR 1.04, 95% CI 0.92 to 1.17) and direct obstetric CFR (aIRR 1.15, 95% CI 0.66 to 2.02). The number of women who were recognised to need and received EmOC was significantly increased overall (aIRR 1.14, 95% CI 1.02 to 1.27), for haemorrhage (aIRR 1.31, 95% CI 1.13 to 1.52) and for postpartum sepsis (aIRR 1.86, 95% CI 1.17 to 2.95). CONCLUSION: Following EmOC&NC training, healthcare providers are more able to recognise and manage complications at time of birth. This trial did not provide evidence that the intervention was effective in reducing adverse clinical outcomes, but demonstrates randomised evaluations are feasible in implementation research. TRIAL REGISTRATION NUMBER: ISRCTN11224105.

Hypertensive disorders in pregnancy: 2019 National guideline.

BACKGROUND: Hypertensive disorders of pregnancy (HDP), including pre-eclampsia/eclampsia, account for significant maternal and fetal mortality globally and especially in South Africa. Objective. To formulate clinical guidelines for the management of HDP in order to substantially reduce the number of maternal deaths from HDP. Methods. The Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument was used to formulate the guidelines and included six domains: scope and purpose; stakeholder involvement; rigour and development; clarity of presentation; applicability; and editorial independence. Recommendations. The guideline stipulates management strategies for all levels of care where women with hypertensive disorders in pregnancy are seen. It also has a detailed implementation plan. Conclusion. A clinical guideline that is of practical value has been formulated by a wide group of stakeholders. It is hoped that its dissemination and implementation by all doctors and nurses will reduce mortality and morbidity associated with HDP.

Development and validation of the African Women Awareness of CANcer (AWACAN) tool for breast and cervical cancer.

BACKGROUND: Measuring factors influencing time to presentation is important in developing and evaluating interventions to promote timely cancer diagnosis, yet there is a lack of validated, culturally relevant measurement tools. This study aimed to develop and validate the African Women Awareness of CANcer (AWACAN) tool to measure awareness of breast and cervical cancer in Sub-Saharan Africa (SSA). METHODS: Development of the AWACAN tool followed 4 steps: 1) Item generation based on existing measures and relevant literature. 2) Refinement of items via assessment of content and face validity using cancer experts' ratings and think aloud interviews with community participants in Uganda and South Africa. 3) Administration of the tool to community participants, university staff and cancer experts for assessment of validity using test-retest reliability (using Intra-Class Correlation (ICC) and adjusted Kappa coefficients), construct validity (comparing expert and community participant responses using t-tests) and internal reliability (using the Kuder-Richarson (KR-20) coefficient). 4) Translation of the final AWACAN tool into isiXhosa and Acholi. RESULTS: ICC scores indicated good test-retest reliability (≥ 0.7) for all breast cancer knowledge domains and cervical cancer risk factor and lay belief domains. Experts had higher knowledge of breast cancer risk factors (p < 0.001), and cervical cancer risk factors (p = 0.003) and symptoms (p = 0.001) than community participants, but similar knowledge of breast cancer symptoms (p = 0.066). Internal reliability for breast cancer risk factors, lay beliefs and symptom and cervical cancer symptom subscales was good with KR-20 values > 0.7, and lower (0.6) for the cervical cancer risk subscale. CONCLUSION: The final AWACAN tool includes items on socio-demographic details; breast and cervical cancer symptom awareness, risk factor awareness, lay beliefs, anticipated help-seeking behaviour; and barriers to seeking care. The tools showed evidence of content, face, construct and internal validity and test-retrest reliability and are available for use in SSA in three languages.

Maternal and perinatal outcomes after caesarean delivery in early and late onset preeclampsia with HIV positive and HIV negative South African Women.

OBJECTIVE: We analyzed the maternal and perinatal outcomes in early onset preeclampsia (EOPE) and late onset preeclampsia (LOPE) pregnant women who had scheduled caesarean deliveries. We sub-analyzed the two categories into HIV positive and HIV negative. PATIENTS AND METHODS: This prospective study was conducted at a regional hospital in Durban, South Africa during 14 months. A total of 14304 deliveries were registered. Out of the 1759 preeclampsia, 351 (19.9%) were EOPE and 1408 (80.1%) were LOPE. Hundred and twenty preeclamptics (n = 120) scheduled for caesarean delivery were selected and divided into two categories namely EOPE (n = 60) and LOPE (n = 60). Each preeclampsia category was then further stratified into HIV positive (n = 30) and HIV negative (n = 30) groups. Maternal demographic, clinical details for preeclampsia, blood laboratory tests, maternal, and perinatal outcomes were recorded. RESULTS: Women with EOPE were older compared to those with LOPE (P = 0.0001). Also the HIV positive women were older compared to the HIV negative groups in both EOPE and LOPE categories (P = 0.03). However, multiparous and primiparous were predominant in EOPE and LOPE categories, respectively (P = 0.00 and P = 0.00). The severity of hypertension and the HIV status did not differentiate the 2 groups. Overall, maternal complications (eclampsia, persistent postpartum hypertension, HELLP syndrome, maternal death) and poor fetal outcomes occurred predominately in EOPE. CONCLUSION: This study confirms the heterogeneity of preeclampsia and shows that the timing of onset of this pregnancy disorder is important to disease severity. Further HIV status influences maternal and neonatal outcome.

Reducing maternal deaths by skills-and-drills training in managing obstetric emergencies: A before-and-after observational study.

BACKGROUND: The institutional maternal mortality ratio (iMMR) in South Africa (SA) is still unacceptably high. A key recommendation from the National Committee on Confidential Enquiries into Maternal Deaths has been to improve the availability and quality of care for women suffering obstetric emergencies. OBJECTIVES: To determine whether there was a change in the number of maternal deaths and in the iMMR over time that could be attributed to the training of >80% of healthcare professionals by means of a specifically designed emergency obstetric care (EmOC) training programme. METHODS: A before-and-after study was conducted in 12 healthcare districts in SA, with the remaining 40 districts serving as a comparison group. Twelve 'most-in-need' healthcare districts in SA were selected using a composite scoring system. Multiprofessional skills-and-drills workshops were held off-site using the Essential Steps in Managing Obstetric Emergencies and Emergency Obstetric Simulation Training programme. Eighty percent or more of healthcare professionals providing maternity care in each district were trained between October 2012 and March 2015. Institutional births and maternal deaths were assessed for the period January 2011 - December 2016 and a before-and-after-training comparison was made. The number of maternal deaths and the iMMR were used as outcome measures. RESULTS: A total of 3 237 healthcare professionals were trained at 346 workshops. In all, 1 248 333 live births and 2 212 maternal deaths were identified and reviewed for cause of death as part of the SA confidential enquiries. During the same period there were 5 961 maternal deaths and 5 439 870 live births in the remaining 40 districts. Significant reductions of 29.3% in the number of maternal deaths (risk ratio (RR) 0.71, 95% confidence interval (CI) 0.66 - 0.77) and 17.5% in the number of maternal deaths from direct obstetric causes (RR 0.825, 95% CI 0.73 - 0.93) were recorded. When comparing the percentage change in iMMR for equivalent before-and-after periods, there was a greater reduction in all categories of causes of maternal death in the intervention districts than in the comparison districts. CONCLUSIONS: Implementing a skills-and-drills EmOC training package was associated with a significant reduction in maternal deaths.

The Screening of Nails for Selected Essential and Toxic Elements in Normotensive and Pre-Eclamptic Women.

To compare the concentrations of 13 different elements in nail samples from pre-eclamptic and normotensive pregnant women. The study site was a regional hospital in Durban, KwaZulu Natal. Nail samples were collected from normotensive (n = 33) and pre-eclamptic (n = 33) pregnant women. Approximately 0.02 g of nail samples were digested in 70% nitric acid and analyzed using inductively coupled plasma-optical emission spectrometry. Analytes of interest were the following essential elements calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), nickel (Ni), selenium (Se) and Zinc (Zn) as well as toxic elements, arsenic (As), cadmium (Cd) and lead (Pb). The observed concentrations of bioelements (mean, µg/g), Ca: normotensive (N) 3467 ± 197 vs (PE) 2897 ± 190; Mg: (N) 736 ± 61 vs (PE) 695 ± 59, were lower in pre-eclampsia albeit not statistically significant. Similarly, the observed concentrations of bioelements (mean, µg/g), Cd: (N) 3 ± 0.3 vs (PE) 2 ± 0.4; Co: (N) 3 ± 0.3 (PE) not detected; Mn: (N) 7 ± 1 (PE) 4 ± 0.8, were significantly lower in pre-eclampsia (p = 0.004, 0.0001 and 0.022, respectively). Therefore, this study demonstrated significantly lower levels of Cd, Co and Mn in pre-eclampsia which justifies the need for further research on these elements towards the effective management or prevention of pre-eclampsia which could ultimately also aid in establishing its pathogenesis.

Adherence to iron prophylactic therapy during pregnancy in an urban regional hospital in South Africa

Background: Iron and folic acid supplementation plays a major role in the prevention and control of iron-deficiency anaemia in pregnancy. Therefore, this study assesses adherence to prophylactic iron supplementation during the antenatal period in South Africa. Methods: An observational study was conducted in a regional hospital from January to December 2016. HIV-uninfected(n= 100) and HIV-infected (n= 100)] women were enrolled and subdivided into three groups: (a)≤34 weeks (n= 33), (b)34­36 weeks (n= 34) and (c)≥37 weeks (n= 33) gestational age respectively. A structured questionnaire was used for data collection. Data were coded and statistically analysed using SPSS software. Pill count and self-reported data from women (n= 24) at≤34 weeks and 34­36 weeks reflected < 50% adherence and 46% non-adherence, being higher in the HIV-infected women (75%). Nausea was the commonest side effect across all trimesters (79. 2%). Adherence (27.8%) and non-adherence (72.1%) to iron, folic acid and calcium supplementation were found in 88% of women. Conclusion: This study found that adherence to micronutrient supplementation is low in pregnancy, albeit higher in HIV-infected women receiving antenatal care at a regional hospital in Durban, South Africa

Obstetrics knowledge and skills training as a catalyst for change.

BACKGROUND: Poor emergency obstetric care has been shown by national confidential enquiries into maternal deaths to contribute to a number of maternal deaths in South Africa. OBJECTIVES: To assess whether a structured training course can improve knowledge and skills and whether this can influence the capacity of a healthcare facility to provide basic and comprehensive emergency obstetric care signal functions. METHODS: A baseline survey was conducted to assess the seven basic emergency obstetric and neonatal care signal functions in 51 community health centres (CHCs) and the nine comprehensive emergency care signal functions in 62 district hospitals (DHs). A re-assessment was conducted 1 year after saturation training had been provided in each district. The delegates were trained using a structured training programme (Essential Steps in Managing Obstetric Emergencies, ESMOE) and their knowledge and skills were tested before and after the training. Saturation training was considered to have been achieved once 80% of the healthcare professionals involved in maternity care had been trained. RESULTS: There was a significant improvement in the knowledge and skills of doctors, namely by 16.8% and 32.8%, respectively, of advanced midwives by 13.7% and 29.0%, and of professional nurses with midwifery by 16.1% and 31.2%. The seven basic emergency care functions improved from 60.8% to 67.8% in the CHCs and from 90.7% to 92.5% in the DHs before and after training. If the two signal functions that are not within the scope of practice of professional nurses with midwifery are excluded (viz. assisted delivery and manual vacuum aspiration), the functionality of CHCs increased from 85.1% to 94.9%. CONCLUSIONS: The ESMOE training programme improved knowledge and skills, but there was a modest improvement in the functionality of the facilities. Improvement in functionality requires changes in the structure of the health system, including changing the scope of practice of professional nurses with midwifery and employing more advanced midwives in CHCs.
