The need for biokineticists in the South African public health care system

Background: Noncommunicable diseases (NCDs) are increasingly prevalent within South Africa. Physical inactivity is a significant, independent and modifiable risk factor increasing the prevalence of NCDs.Discussion: The integration of physical activity programmes into the primary health care system through multidisciplinary platforms is thus advocated for and envisioned to be more cost-effective than current practices. However, currently within the primary health care setting of South Africa, there is an absence of health care professionals adequately equipped to develop and implement physical activity programmes. Biokineticists, whose scope of practice is to improve physical functioning and health through exercise as a modality, are ideally suited to developing and implementing physical activity programmes in the public sector. Yet despite their evident demand, the role of the biokineticist is not incorporated into the national public health care system.Conclusion: This short report calls firstly, for the inclusion of biokinetics into the public health care sector, and secondly, for the funding of multidisciplinary community health programmes supporting education, healthy eating and physical activity levels.Keywords: noncommunicable disease, physical activity, community health programme, primary health car

A 12-week primary prevention programme and its effect on health outcomes (the Sweet Hearts biokinetics pilot study)

Background: The prevalence of non-communicable diseases (NCDs) and physical inactivity are concerning within the South African population. To address these concerns, the ‘Strategic Plan for Prevention and Control of NCDs 2013-2017’ was developed. In response to this plan, a 12-week pilot biokinetics community health programme, Sweet Hearts, was initiated. Methods: This study is a prospective pilot study evaluating the feasibility and effectiveness of the intervention. Twenty- five individuals participated in the intervention. Ten participants performed a battery of physiological tests pre and post intervention and 5 participants completed an email-based survey post intervention. The setting of the study was Tramway Football Club, Southfield, Cape Town, South Africa. The Sweet Hearts intervention was designed to promote physical activity and healthy nutritional habits in those who participated. A total of 27 exercise sessions consisting of cardiovascular, resistance and flexibility training were conducted. Brief-behavioural counselling was integrated into exercise sessions. Results: The intervention group had a high attrition rate with >50% of participants not presenting for post-intervention testing. Results were evident despite a limited sample size. There were significant improvements in health outcome measures among participants who did attend all testing sessions. These improvements included: an increase in Global Physical Activity Questionnaire (GPAQ) score (p = 0.03), 12- minute walk distance (p = 0.01), sit-to-stand test repetitions (p = 0.001), and a decrease in waist circumference (p = 0.01). Improvements were also noted in self-reported eating restraint (p = 0.03). Five main themes were structured into post intervention surveys: 1) enjoyment of the intervention, 2) benefits of the intervention, 3) obstacles affecting adherence, 4) future improvements to the intervention, and 5) state of non-communicable diseases in South Africa. Conclusion: The results of the Sweet Hearts intervention demonstrate the difficulty and importance of maintaining adherence to a community health intervention. The favourable results of the small sample size demonstrate the potential benefit of biokinetics-based programmes in the public health sector; and provide proof of concept for the dedication of resources towards health promotion within a community setting.

Remote Ischaemic Conditioning in STEMI Patients in Sub-Saharan AFRICA: Rationale and Study Design for the RIC-AFRICA Trial

Purpose: Despite evidence of myocardial infarct size reduction in animal studies, remote ischaemic conditioning (RIC) failed to improve clinical outcomes in the large CONDI-2/ERIC-PPCI trial. Potential reasons include that the predominantly low-risk study participants all received timely optimal reperfusion therapy by primary percutaneous coronary intervention (PPCI). Whether RIC can improve clinical outcomes in higher-risk STEMI patients in environments with poor access to early reperfusion or PPCI will be investigated in the RIC-AFRICA trial. // Methods: The RIC-AFRICA study is a sub-Saharan African multi-centre, randomized, double-blind, sham-controlled clinical trial designed to test the impact of RIC on the composite endpoint of 30-day mortality and heart failure in 1200 adult STEMI patients without access to PPCI. Randomized participants will be stratified by whether or not they receive thrombolytic therapy within 12 h or arrive outside the thrombolytic window (12–24 h). Participants will receive either RIC (four 5-min cycles of inflation [20 mmHg above systolic blood pressure] and deflation of an automated blood pressure cuff placed on the upper arm) or sham control (similar protocol but with low-pressure inflation of 20 mmHg and deflation) within 1 h of thrombolysis and applied daily for the next 2 days. STEMI patients arriving greater than 24 h after chest pain but within 72 h will be recruited to participate in a concurrently running independent observational arm. // Conclusion: The RIC-AFRICA trial will determine whether RIC can reduce rates of death and heart failure in higher-risk sub-optimally reperfused STEMI patients, thereby providing a low-cost, non-invasive therapy for improving health outcomes

Innovation policy and higher education in South Africa: addressing the challenge

The South African Department of Science and Technology Ten Year Plan seeks to move the system of innovation toward growing a knowledge economy. It sets ambitious targets for scientific production (PhD graduates; world share of scientific publications) whose attainment in part rests on the effectiveness of the universities. The paper commences with a thumbnail sketch of the system of innovation. This is followed by a discussion of the international ranking of universities and South Africa's standing. Next we provide a comparative analysis of the domestic ranking of universities. A limited survey of five countries shows that concentration of research in a cluster of universities is 'normal'. Turning to the South African case we use the national R&D Surveys (HSRC, 2008) to examine the changing diversity among the universities over the merger period. This reveals two concentrations, the first comprising the 'Big Five' research institutions and second the 'Next Six.' This implies a double gap in the distribution of universities according to research expenditure and appears to be a feature unique to the South African higher education system. We then unpack the meaning of the targets of the Ten Year Plan and analyze the potential of the universities to meet these in the light of the gaps. The paper concludes with suggestions for policy.

National survey of research & experimental development 2005/06

Commissioned by the Department of Science and TechnologyThis Report presents the results of the fourth R&D Survey that the Centre for Science, Technology and Innovation Indicators (CeSTII) has conducted for the Department of Science and Technology, namely the 2005/06 Survey of Inputs into Research and Experimental Development (R&D). The 2005/06 R&D Survey is a benchmark survey in that it is the last before the enhanced R&D tax incentive that came into effect on 2 November 2006. As previously, the survey methodology follows the OECD Frascati Manual guidelines. The questionnaire included standard items as well as inquiring more deeply into staff demographics, R&D collaboration, higher education funding, research in the areas emphasized in the South African R&D Strategy of 2002, as well as in the emerging areas of biotechnology and nanotechnology
