Implementation Science Workshop 2024
Building capacity for the use of implementation science. The Principal Investigators of the project; Dr Phindile Shangase from UFS, left, and Dr Lebogang Mogongoa from the Central University of Technology, with Dr Shalini Ahuja from King’s College London, centre, who facilitated the workshops.

The Division of Public Health at the University of the Free State (UFS) together with the Central University of Technology (CUT), held a successful workshop (first phase) for their project: Capacity building for the use of implementation science in various typologies in low- and middle-income countries for the prevention and/or management of the quadruple burden of disease.

According to the National Institute for Health as well as the World Health Organisation, implementation science supports innovative approaches to identifying, understanding, and overcoming barriers to the adoption, adaptation, integration, scale-up and sustainability of evidence-based interventions, tools, policies, and guidelines. Implementation research therefore pertains to gathering and analysing implementation evidence of effectiveness that determines if the intervention works in real-world circumstances.

The Principal Investigator at UFS is Dr Phindile Shangase from the Division of Public Health, supported by colleagues in the Division, as well as the CUT team, led by Dr Lebogang Mogongoa. The first phase of the project took place from 14-17 October 2024 with the first two days held at UFS.

In this co-funded project, UFS and CUT engage in partnership capacity building for academics and postgraduate students. At the UFS, the project is funded by the Office of the Deputy Vice-Chancellor: Research and Internationalisation and resulted from the CUT and UFS Joint Research Programme Research Grant 9th Call.

Contributing to evidence-based policies and practices

Dr Shangase says the workshops of this project were well attended by academics, researchers, postgraduate and postdoctoral students from different disciplines, and community organisations, including programme managers, as well as clinicians from the Department of Health. Other stakeholders and international students who could not travel for face-to-face interactions attended live on UFS YouTube.

Workshops were facilitated by Dr Shalini Ahuja from King’s College, London, who is an international expert and experienced in this field through engaging in research as well as field facilitation in various low- and middle-income countries.

Says Dr Shangase: “Implementation science is the study of methods and strategies to promote the systematic uptake of research findings. It contributes to evidence-based policies and practices and ensures that they are implemented effectively to achieve their intended outcomes, through the identification of barriers and facilitators to implementation. These strategies can therefore be integrated effectively into routine practice in healthcare, public health, and other fields.

“Reviewed studies indicate that the effectiveness of implementation research is noted in the identification and investigation of factors that address disparities in healthcare delivery and outcomes, including those within the health systems and in the population. In simple terms, the goal of implementation science is to understand how and why some interventions succeed while others fail, and to identify the best ways to integrate research-backed interventions into real-world settings for maximum impact and to ensure they continue to be used and remain effective over time,” says Dr Shangase.

Purpose of project

According to her, in the context of South Africa, implementation science has potential to assist in addressing the quadruple burden of disease which comprise of these colliding epidemics: maternal, newborn and child health; HIV/AIDS and tuberculosis (TB); non-communicable diseases (e.g. cardiovascular diseases, chronic respiratory diseases, cancers, and diabetes); and violence and injury.

The purpose of this project, explains Dr Shangase, is to capacitate academics and postgraduate students at the UFS and CUT as well as community stakeholders with knowledge and skills regarding the processes and factors involved in the successful integration of evidence-based public health improvement interventions into routine practice and policy.

“Implementation science offers a strategic, data-driven approach for South Africa, especially in addressing the country’s unique and complex healthcare challenges. These advantages stem from its focus on translating evidence-based interventions into real-world practice, addressing the quadruple burden of disease and helping overcome systemic obstacles to effective healthcare delivery.

“These advantages make implementation science a vital tool for improving health outcomes and achieving sustainable public health progress in South Africa.”

The next phase of this project is expected to be more innovative and takes place between February and March in 2025 with the inclusion of a multistakeholder team.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
