RESUMO

For over a decade, the global health community has advanced policy engagement with migration and health, as reflected in multiple global-led initiatives. These initiatives have called on governments to provide universal health coverage to all people, regardless of their migratory and/or legal status. South Africa is a middle-income country that experiences high levels of cross-border and internal migration, with the right to health enshrined in its Constitution. A National Health Insurance Bill also commits the South African public health system to universal health coverage, including for migrant and mobile groups. We conducted a study of government policy documents (from the health sector and other sectors) that in our view should be relevant to issues of migration and health, at national and subnational levels in South Africa. We did so to explore how migration is framed by key government decision makers, and to understand whether positions present in the documents support a migrant-aware and migrant-inclusive approach, in line with South Africa's policy commitments. This study was conducted between 2019 and 2021, and included analysis of 227 documents, from 2002-2019. Fewer than half the documents identified (101) engaged directly with migration as an issue, indicating a lack of prioritisation in the policy discourse. Across these documents, we found that the language or discourse across government levels and sectors focused mainly on the potential negative aspects of migration, including in policies that explicitly refer to health. The discourse often emphasised the prevalence of cross-border migration and diseases, the relationship between immigration and security risks, and the burden of migration on health systems and other government resources. These positions attribute blame to migrant groups, potentially fuelling nationalist and anti-migrant sentiment and largely obscuring the issue of internal mobility, all of which could also undermine the constructive engagement necessary to support effective responses to migration and health. We provide suggestions on how to advance engagement with issues of migration and health in order for South Africa and countries of a similar context in regard to migration to meet the goal of inclusion and equity for migrant and mobile groups.

RESUMO

COVID-19 ushered in public health guidelines restricting face-to-face contact and movement, and encouraging social distancing, all of which had implications for conducting field-based research during the pandemic. For qualitative researchers, this meant adapting conventional face-to-face methods and resorting to virtual variations of the same in adherence to stipulated COVID-19 health protocols. Virtual qualitative research introduced new concerns and logistical challenges. This paper presents critical reflections on experiences of conducting qualitative research during the pandemic, from the perspectives of a cohort of postgraduate fellows. A critical reflection framework was utilised to explore fellows experiences and meanings ascribed to their experiences. The research findings illustrate three overarching processes which, in turn, shaped ways of thinking, doing and being. First, explicating tacit assumptions about their anticipated research journeys and interrogating these. Second, shifts in power differentials demonstrated by role reversal between researchers and participants, and between fellows and supervisors as they re-negotiated their positionalities in virtual research spaces. Third, context specific sense-making, in which - narrative accounts support the notion of knowledge as a social construct. Our findings have important implications for qualitative research practice. Our study documents methodological nuances and social implications of conducting qualitative research during COVID-19 and in a-South African context. In addition, our study exemplifies the use of critical reflection in qualitative research practice in the specific context of postgraduate academic research. Further, our study illustrates how the use of technology shapes qualitative research protocol development, data collection and analysis phases.

RESUMO

To better understand and plan health systems featuring multiple levels and complex causal elements, there have been increasing attempts to incorporate tools arising from complexity science to inform decisions. The utilization of new planning approaches can have important implications for the types of evidence that inform health policymaking and the mechanisms through which they do so. This paper presents an empirical analysis of the application of one such tool-system dynamics modelling (SDM)-within a tuberculosis control programme in South Africa in order to explore how SDM was utilized, and to reflect on the implications for evidence-informed health policymaking. We observed group model building workshops that served to develop the SDM process and undertook 19 qualitative interviews with policymakers and practitioners who partook in these workshops. We analysed the relationship between the SDM process and the use of evidence for policymaking through four conceptual perspectives: (1) a rationalist knowledge-translation view that considers how previously-generated research can be taken up into policy; (2) a programmatic approach that considers existing goals and tasks of decision-makers, and how evidence might address them; (3) a social constructivist lens exploring how the process of using an evidentiary planning tool like SDM can shape the understanding of problems and their solutions; and (4) a normative perspective that recognizes that stakeholders may have different priorities, and thus considers which groups are included and represented in the process. Each perspective can provide useful insights into the SDM process and the political nature of evidence use. In particular, SDM can provide technical information to solve problems, potentially leave out other concerns and influence how problems are conceptualized by formalizing the boundaries of the policy problem and delineating particular solution sets. Undertaking the process further involves choices on stakeholder inclusion affecting whose interests may be served as evidence to inform decisions.

RESUMO

Incentive-based interventions are used to encourage HIV testing, linkage to HIV care, and antiretroviral therapy (ART) adherence. Studies assessing efficacy of cash incentives have raised questions about the perceived ethicality of and attitudes towards incentives. Here we explore patients' and health providers' perspectives of the acceptability of a conditional cash transfer for ART initiation after receiving a positive HIV test through community-based services in resource-poor communities in Cape Town, South Africa. Drawing on in-depth interviews with patients and health care workers (HCWs), we find that, despite the perception that cash incentives are effective in promoting ART initiation, significant ambivalence surrounds the acceptability of such incentives. The receipt of a financial incentive was highly moralized, and fraught with challenges. Increasing the acceptability of cash incentives through careful design and delivery of interventions is central to the potential of this type of intervention for improving outcomes along the HIV care continuum.

RESUMO

BACKGROUND: With the aim to support further understanding of scaling up and sustaining digital health, we explore digital health solutions that have or are anticipated to reach national scale in South Africa: the Perinatal Problem Identification Programme (PPIP) and Child Healthcare Problem Identification Programme (Child PIP) (mortality audit reporting and visualisation tools), MomConnect (a direct to consumer maternal messaging and feedback service) and CommCare (a community health worker data capture and decision-support application). RESULTS: A framework integrating complexity and scaling up processes was used to conceptually orient the study. Findings are presented by case in four domains: value proposition, actors, technology and organisational context. The scale and use of PPIP and Child PIP were driven by 'champions'; clinicians who developed technically simple tools to digitise clinical audit data. Top-down political will at the national level drove the scaling of MomConnect, supported by ongoing financial and technical support from donors and technical partners. Donor preferences played a significant role in the selection of CommCare as the platform to digitise community health worker service information, with a focus on HIV and TB. A key driver of scale across cases is leadership that recognises and advocates for the value of the digital health solution. The technology need not be complex but must navigate the complexity of operating within an overburdened and fragmented South African health system. Inadequate and unsustained investment from donors and government, particularly in human resource capacity and robust monitioring and evaluation, continue to threaten the sustainability of digital health solutions. CONCLUSIONS: There is no single pathway to achieving scale up or sustainability, and there will be successes and challenges regardless of the configuration of the domains of value proposition, technology, actors and organisational context. While scaling and sustaining digital solutions has its technological challenges, perhaps more complex are the idiosyncratic factors and nature of the relationships between actors involved. Scaling up and sustaining digital solutions need to account for the interplay of the various technical and social dimensions involved in supporting digital solutions to succeed, particularly in health systems that are themselves social and political dynamic systems.

RESUMO

This study explored the relationship between sexual health and religion among young, Pentecostal Christian women navigating the transition to adulthood in Khayelitsha township, in the City of Capetown, South Africa. Between February and August 2019, eleven semi-structured interviews and three focus group discussions were conducted. Thematic analysis and discourse analysis were used to analyse the data collected. The study found that the relationship between sexual health and religion was complex and multifaceted, shaped by the religious dichotomisation of "right" and "wrong", socio-economic constraints and culture. Despite the perceived decline of religious influence on the sexual and social lives of youth, religion continues to play an instrumental role in shaping the dreams, aspirations and lifestyles of young people, especially as they transition to adulthood. We argue therefore, that religion is a significant spiritual and cultural resource that young women use to develop their sexual and social identities, although it cannot always be equated with their sexual practice or decision-making related to sexual health. In the light of this, churches should still be seen as key partners in the fight against HIV as their involvement can act as a stabilising force for young people dealing with poverty and uncertainty. Church engagement with young people should offer programmes that include but are not limited to sexual health.

RESUMO

Bergenin is a C-glycoside of 4-O-methylgallic acid that is isolated from medicinal plants such as Flueggea leucopyrus, Bergenia crassifolia, Mallotus philippensis, Corylopsis spicata, Caesalpinia digyna, Mallotus japonicus, and Sacoglottis gabonensis. Even though there appears to be ample evidence from South Asian traditional medicine that bergenin possesses strong anticancer activity, no comprehensive scientific study has been carried out to test its anticancer potency. Therefore, in this study, the potential mechanisms of action for bergenin's postulated anticancer activity were examined using computational techniques. Firstly, bergenin was tested for its toxicity as a drug candidate using in silico toxicity analysis. It was found that bergenin is nontoxic according to modern toxicity measures. The optimized structure of bergenin was obtained at the DFT-B3LYP/6-31G(d) level of theory. Potential biological targets of bergenin were identified using reverse docking calculations. Reverse docking results suggested that galectin-3 is a potential target of bergenin. Gelectin-3 is an enzyme that plays a major role in cell-cell adhesion, cell-matrix interactions, macrophage activation, angiogenesis, metastasis, and apoptosis in cancer, making it a popular target in anticancer drug design. Among the many potential biological targets predicted by reverse docking calculations, galectin-3 was selected as it complies with the primary objective of this study. The binding of bergenin to galectin-3 was studied by conventional forward docking calculations. Classical molecular dynamics (MD) simulations were used to study the stability of the galectin-3:bergenin complex. Docking calculations indicated that bergenin has the potential to effectively bind to the carbohydrate recognition domain (CRD) of galectin-3. As well as electrostatic and van der Waals interactions, a few strong hydrogen bonds were found to be involved in the binding of bergenin to galectin-3. There is also a plausible π-stacking interaction between the aromatic moiety of bergenin and the His158 residue at the binding site. A 50-ns MD simulation was carried out for the bergenin:galectin-3 complex in a cubic water box with periodic boundary conditions. The MD results showed that the bergenin:galectin-3 complex is highly stable and confirmed the veracity of the docking results, which suggested that bergenin potentially exerts an inhibitory effect on galectin-3. This study therefore sheds new light on the anticancer activity of bergenin and demonstrates that bergenin could potentially be used to develop more potent galectin-3 inhibitors. The study also provides scientific evidence supporting the use of bergenin-containing plants in cancer treatments in Eastern traditional medicine.
