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.

To tan or not to tan: a burning issue

2009-12-08

Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
