    The future cost of cancer in South Africa: An interdisciplinary cost management strategy

    Get PDF
    The exponential rise in cancer costs in South Africa (SA) was illustrated in a recent Sunday Times article entitled ‘The cost of cancer can be a debt sentence’.[1] Our minister of health talks of a ‘war’ against the high costs of cancer drugs, and epidemiologists project a sharply rising incidence. Eminent international medical journals, such as The Lancet, underline the fact that cancer cost is a growing international problem that confronts even the richest countries. Indeed, the question may be posed: if richer countries in the world are battling to cover the costs of cancer, what is the prognosis for SA

    The results are described of a transcultural psychiatric study of schizophrenia undertaken by WHO in nine countries. The study proved that such a collaboration was feasible, that it was possible to develop research procedures for international use, and that similar types of schizophrenia could be found in each of the countries involved. One thousand two hundred and two patients were studied and over 2 million items of information obtaine

    Impact of Implementing Antenatal Syphilis Point-of-Care Testing on Maternal Mortality in KwaZulu-Natal, South Africa: An Interrupted Time Series Analysis.

    BACKGROUND: Syphilis infection has been associated with an increased risk of HIV infection during pregnancy which poses greater risk for maternal mortality, and antenatal syphilis point-of-care (POC) testing has been introduced to improve maternal and child health outcomes. There is limited evidence on the impact of syphilis POC testing on maternal outcomes in high HIV prevalent settings. We used syphilis POC testing as a model to evaluate the impact of POC diagnostics on the improvement of maternal mortality in KwaZulu-Natal, South Africa. METHODS: We extracted 132 monthly data points on the number of maternal deaths in facilities and number of live births in facilities for 12 tertiary healthcare facilities in KwaZulu-Natal (KZN), South Africa from 2004 to 2014 from District Health Information System (DHIS) health facility archived. We employed segmented Poisson regression analysis of interrupted time series to assess the impact of the exposure on maternal mortality ratio (MMR) before and after the implementation of antenatal syphilis POC testing. We processed and analyzed data using Stata Statistical Software: Release 13. (Stata, Corp LP, College Station, TX, USA). RESULTS: The provincial average annual maternal mortality ratio (MMR) was estimated at 176.09 ± 43.92 ranging from a minimum of 68.48 to maximum of 225.49 per 100,000 live births. The data comprised 36 temporal points before the introduction of syphilis POC test exposure and 84 after the introduction in primary health care clinics in KZN. The average annual MMR for KZN from 2004 to 2014 was estimated at 176.09 ± 43.92. A decrease in MMR level was observed during 2008 after syphilis POC test implementation, followed by a rise during 2009. Analysis of the MMR trend estimates a significant 1.5% increase in MMR trends during the period before implementation and 1.3% increase after implementation of syphilis POC testing (p < 0.001). CONCLUSION: Although our finding suggests a brief reduction in the MMR trend after the implementation of antenatal syphilis POC testing, a continued increase in syphilis rates is seen in KwaZulu-Natal, South Africa. The study used one of the most powerful quasi-experimental research methods, segmented Poisson regression analysis of interrupted time series to model the impact of syphilis POC on maternal outcome. The study finding requires confirmation by use of more rigorous primary study design

    Reported stigma and discrimination by people with a diagnosis of schizophrenia

    Aims. This article examines the extent of stigma and discrimination as reported by people with a diagnosis of schizophrenia. The hypothesis is that when people express in their own words the discrimination they experience such discrimination will be found to be widespread. Methods. Seventy-five people with a diagnosis of schizophrenia from 15 different countries were interviewed with a mixed methods instrument to assess reported discrimination. The data were analysed for frequency counts and then a thematic analysis was performed. A conceptual map is provided. Results. The study was a cross-cultural one but, contrary to expectations, few transnational differences were found. The main hypothesis was supported. Conversely, we found that when participants reported ‘positive discrimination', this could as easily be conceptualised as being treated similarly to how others in society would expect to be treated. Conclusion. Negative discrimination is ubiquitous and sometimes connotatively very strong, with reports of humiliation and abuse. ‘Positive discrimination' conversely indicates that people with a mental illness diagnosis expect discrimination and are grateful when it does not occur. The literature on self-stigma is discussed and found wanting. Similarly, the theory that contact with mentally ill people reduces stigma and discrimination is not fully supported by our result

    An investigation of the efficiency of South Africa’s sector education and training authorities (SETA’s)

    Get PDF
    The performance of South African Sector Education and Training Authorities (SETA’s) has been increasingly questioned. On this premise, the paper investigated the efficiency of the SETAs with respect to their utilization of funds in order to promote a range of education and training outputs was investigated. More specifically, the study investigated the quantity and quality of five training and education outputs, set by the National Skills Development Strategy (NSDS), in relation to the funding received. Furthermore, the study examined the amount of money spend on administrative expenditure by the various SETAs, as well as the SETAs management of financial reserves. In order to guide the study, as well as analyze the data, a conceptual framework to measure efficiency was based on an input-output model developed by Gupta and Verhoeven (2001). Data were obtained from the published accounting and annual reports for the period 2006 – 2009. The results indicated only two of the SETA’s were efficient with respect to their utilization of funds and that only five SETA’s consistently met their own targets. The study also shows that if the SETA’ s funds had been applied to education and training outputs, rather than for investment purposes, training outputs could have been considerably increased. The paper has implications for the use of public funds with respect to the critical skills shortage confronting the economy

    Circulating microRNA's as a diagnostic tool for hepatocellular carcinoma in a hyper endemic HIV setting, KwaZulu-Natal, South Africa: a case control study protocol focusing on viral etiology.

    Get PDF
    BACKGROUND: A wide range of studies has investigated the diagnostic proficiency of extracellular microRNAs (miRNAs) in hepatocellular cancer (HCC). HCC is expected to increase in Sub-Saharan Africa (SSA), due to endemic levels of viral infection (HBV/HIV), ageing and changing lifestyles. This unique aetiological background provides an opportunity for investigating potentially novel circulating miRNAs as biomarkers for HCC in a prospective study in South Africa. METHODS: This study will recruit HCC patients from two South African cancer hospitals, situated in Durban and Pietermaritzburg in the province of KwaZulu-Natal. These cases will include both HBV mono-infected and HBV/HIV co-infected HCC cases. The control group will consist of two (2) age and sex-matched healthy population controls per HCC case randomly selected from a Durban based laboratory. The controls will exclude patients if they have any evidence of chronic liver disease. A standardised reporting approach will be adopted to detect, quantify and normalize the level of circulating miRNAs in the blood sera of HCC cases and their controls. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) will be employed to quantity extracellular miRNAs. Differences in concentration of relevant miRNA by case/control status will be assessed using the Wilcoxon rank-sum (Mann-Whitney U) test. Adjustment for multiple testing (Bonferroni correction), receiver operating curves (ROC) and optimal breakpoint analyses will be employed to identify potential thresholds for the differentiation of miRNA levels of HCC cases and their controls. DISCUSSION: Although there is a growing base of literature regarding the role of circulating miRNAs as biomarkers, this promising field remains a 'work in progress'. The aetiology of HBV infection in HCC is well understood, as well as it's role in miRNA deregulation, however, the mediating role of HIV infection is unknown. HCC incidence in SSA, including South Africa, is expected to increase significantly in the next decade. A combination of factors, therefore, offers a unique opportunity to identify candidate circulating miRNAs as potential biomarkers for HBV/HIV infected HCC

    Electroconvulsive therapy does not alter the synaptic protein neurogranin in the cerebrospinal fluid of patients with major depression

    Neurogranin (Ng) is a dendritic protein associated with synaptic plasticity, proposed to be a novel biomarker to measure synaptic dysfunction and degeneration in Alzheimer’s disease. Since electroconvulsive therapy (ECT) has been suggested to facilitate neurogenesis and neural plasticity, we tested whether ECT could modify CSF Ng concentrations measured before and after a course of ECT in 12 patients with major depression. CSF Ng concentrations did not change, but baseline levels were positively correlated with the therapeutic response

    Topographic mapping of the interfaces between human and aquatic mosquito habitats to enable barrier targeting of interventions against malaria vectors.

    Get PDF
    Geophysical topographic metrics of local water accumulation potential are freely available and have long been known as high-resolution predictors of where aquatic habitats for immature mosquitoes are most abundant, resulting in elevated densities of adult malaria vectors and human infection burden. Using existing entomological and epidemiological survey data, here we illustrate how topography can also be used to map out the interfaces between wet, unoccupied valleys and dry, densely populated uplands, where malaria vector densities and infection risk are focally exacerbated. These topographically identifiable geophysical boundaries experience disproportionately high vector densities and malaria transmission risk, because this is where mosquitoes first encounter humans when they search for blood after emerging or ovipositing in the valleys. Geophysical topographic indicators accounted for 67% of variance for vector density but for only 43% for infection prevalence, so they could enable very selective targeting of interventions against the former but not the latter (targeting ratios of 5.7 versus 1.5 to 1, respectively). So, in addition to being useful for targeting larval source management to wet valleys, geophysical topographic indicators may also be used to selectively target adult mosquitoes with insecticidal residual sprays, fencing, vapour emanators or space sprays to barrier areas along their fringes

    This article reports a pioneering golf programme for people with severe and enduring mental health problems. Following a discussion of the problems and possibilities of golf as a form of physical activity for this group, we outline the structure, organisation, and ethos of the golf programme. Through an analysis of qualitative case study data collected during the programme, we discuss the response to the programme from service users and mental health professionals. We conclude by highlighting aspects of the programme which were critical to its success and offering suggestions for further initiatives in this area

    Frequency locking of modulated waves

    Full text link
    We consider the behavior of a modulated wave solution to an S1\mathbb{S}^1-equivariant autonomous system of differential equations under an external forcing of modulated wave type. The modulation frequency of the forcing is assumed to be close to the modulation frequency of the modulated wave solution, while the wave frequency of the forcing is supposed to be far from that of the modulated wave solution. We describe the domain in the three-dimensional control parameter space (of frequencies and amplitude of the forcing) where stable locking of the modulation frequencies of the forcing and the modulated wave solution occurs. Our system is a simplest case scenario for the behavior of self-pulsating lasers under the influence of external periodically modulated optical signals
