Angiogenic imbalance as a contributor to the pathophysiology of preeclampsia among black African women.

OBJECTIVE: The pathogenesis of preeclampsia remains unclear despite extensive research. Altered angiogenic balance has been hypothesized to play a significant role in the clinical manifestations of this syndrome. However this imbalance has not been investigated extensively among black African women. The aim of this study was to investigate the maternal levels of the angiogenic factors soluble vascular endothelial growth factor receptor 1 (sFLT1) and placental growth factor (PlGF) among black African women with preeclampsia. METHODS: A case control study was conducted in the Mthatha hospital complex in South Africa including 51 women with preeclampsia and 82 women with uncomplicated pregnancies. Blood samples were drawn from participants and serum was used to assess sFLT1, and PlGF levels quantified using specific enzyme linked immunosorbent assays. Non- parametric statistics were used for analysis. RESULTS: Black African women with preeclampsia were found to have significantly lower levels of PlGF (90.3 ± 8.9 pg/ml versus 172.8 ± 20.2 pg/ml; p < 0.01), higher sFLT1 (2087.3 ± 200.1 pg/ml versus 1546.5 ± 91.9 pg/ml; p < 0.01) and a higher sFLT1/PIGF ratio (66.8 ± 18.7 versus 22.3 ± 2.9; p < 0.01) compared to black African normotensive controls. CONCLUSION: The results support an altered angiogenic balance may contribute to the pathogenesis/pathophysiology of preeclampsia among black African women as reported in other populations.

Impact of a provider job aid intervention on injectable contraceptive continuation in South Africa.

Arriving late for scheduled contraceptive reinjections is common in many countries and contributes to discontinuation when providers are unsure how to manage such clients. A clinic-randomized cohort and cross-sectional study with more than 5,000 clients using injectable contraceptives was conducted in the Eastern Cape province of South Africa to test the effectiveness of a provider job aid for managing late-returning clients and promoting continued use of the method. A marginally significant difference in reinjection rates between intervention and control groups was found for those up to two weeks late, and reanalysis excluding one clinic that experienced stockout issues revealed a significant difference. The difference in reinjection rates for those 2-12 weeks late was also found to be significant. The one-reinjection cycle continuation rate for the intervention group was higher than that for the control group, but the difference was not statistically significant. Appropriate management of late-returning clients is critical, and this study illustrates that reinjection rates can be significantly increased with a low-resource provider job aid.

Knowledge of termination of pregnancy (TOP) legislation and attitudes toward TOP clinical training among medical students attending two South African universities.

UNLABELLED: Provision of safe, voluntary, termination of pregnancy (TOP) in South Africa is challenged by an insufficient number of TOP-trained clinicians. Medical students' understanding of TOP legality and their attitudes toward TOP training are indicators for future service provision. We administered a 63-item questionnaire to explore these issues at the University of Cape Town and Walter Sisulu University. Ordinary least squares regression assessed predictors of TOP legislation knowledge and training attitudes. RESULTS: Of 1308 students, 95% knew that TOP was legal in South Africa, but few (27%) understood the specific provisions of the legislation beyond 13 weeks' gestation. Sixty-three percent desired more information about TOP. In multivariate models, female, white and sexually experienced students and students more advanced in school had better legislation knowledge (all p < .01). Attending religious services regularly (p < .01) was associated with lack of support for TOP training, whereas being in a relationship (p < .01) was associated with support for TOP training.

Attitudes and intentions regarding abortion provision among medical school students in South Africa.

CONTEXT: Although South Africa liberalized its abortion law in 1996, significant barriers still impede service provision, including the lack of trained and willing providers. A better understanding is needed of medical students' attitudes, beliefs and intentions regarding abortion provision. METHODS: Surveys about abortion attitudes, beliefs and practice intentions were conducted in 2005 and 2007 among 1,308 medical school students attending the University of Cape Town and Walter Sisulu University in South Africa. Bivariate and multivariate analyses identified associations between students' characteristics and their general and conditional support for abortion provision, as well as their intention to act according to personal attitudes and beliefs. RESULTS: Seventy percent of medical students believed that women should have the right to decide whether to have an abortion, and large majorities thought that abortion should be legal in a variety of medical circumstances. Nearly one-quarter of students intended to perform abortions once they were qualified, and 72% said that conscientiously objecting clinicians should be required to refer women for such services. However, one-fifth of students believed that abortion should not be allowed for any reason. Advanced medical students were more likely than others to support abortion provision. In multivariate analyses, year in medical school, race or ethnicity, religious affiliation, relationship status and sexual experience were associated with attitudes, beliefs and intentions regarding provision. CONCLUSIONS: Academic medical institutions must ensure that students understand their responsibilities with respect to abortion care--regardless of their personal views--and must provide appropriate abortion training to those who are willing to offer these services in the future.

Survey of knowledge, attitudes and practices surrounding the intrauterine device in South Africa.

BACKGROUND: The Copper T intrauterine device (IUD) is a safe, effective, reversible contraceptive that is used widely worldwide but little in South Africa. This study assesses the knowledge, attitudes and practices of potential IUD users and health care providers to inform strategies for expanding IUD use in South Africa. STUDY DESIGN: A descriptive, cross-sectional survey was conducted among 205 clients and 32 health care providers at 12 public sector clinics in two provinces. RESULTS: Twenty-six percent of clients had heard of the IUD; of those, 9% had misconceptions or incorrect information that negatively influenced their opinion of the method. After being given a description of the Copper T IUD, 74% said they would consider using it. Provider knowledge about Copper T IUDs was inaccurate and inadequate. Providers held incorrect beliefs about IUD candidate selection and risks. Almost all providers said that they needed more training and information about the IUD. CONCLUSION: If IUD use is to be expanded in South Africa, potential users will need education about the method and providers will need training on counseling and provision.

Timeliness of contraceptive reinjections in South Africa and its relation to unintentional discontinuation.

CONTEXT: Research examining hormonal injectable contraceptive continuation has focused on clients' intentional discontinuation. Little attention, however, has been paid to unintentional discontinuation due to providers' management of clients who would like to continue use but arrive late for their scheduled reinjections. METHODS: A cross-sectional survey of 1,042 continuing injectable clients at 10 public clinics was conducted in South Africa's Western and Eastern Cape provinces. Bivariate logistic regression analyses were used to identify associations between specific variables and the likelihood of receiving a reinjection, among clients who returned to clinics late but within the two-week grace period for reinjection. RESULTS: Of 626 continuing clients in the Western Cape, 29% were up to two weeks late and 25% were 2-12 weeks late for their scheduled reinjection; these proportions among 416 continuing clients in the Eastern Cape were 42% and 16%, respectively. Only 1% of continuing clients in the Western Cape who arrived during the two-week grace period did not receive a reinjection; however, 36% of similar clients in the Eastern Cape did not receive a reinjection. Among late clients in the Eastern Cape who did not receive a reinjection, 64% did not receive any other method. Few variables were significant in bivariate analyses; however, certain characteristics were associated with receiving reinjections among late clients in the Eastern Cape. CONCLUSIONS: It is common for clients to arrive late for reinjections in this setting. Providers should adhere to protocols for the reinjection grace period and have a contraceptive coverage plan for clients arriving past the grace period to reduce clients' risk of unintentional discontinuation and unintended pregnancy.
