Prof Champion Nyoni, Senior Researcher in the School of Nursing at the University of the Free State (UFS), has been appointed to the World Health Organisation (WHO) Academy Standing Advisory Quality Committee – making him the only representative from Africa to serve in this academy.

Another UFS staff member, Prof Motlalepula Matsabisa, an expert on African traditional medicine and Head of the African Medicines Innovations and Technologies Development Platform (AMITD) within the Department of Pharmacology, has also been appointed to serve on a WHO initiative – the WHO Global Centre for Traditional Medicine Editorial Board/Evidence Task Force. His appointment will be effective until the end of December 2023.

Prof Matsabisa will also attend the first WHO Traditional Medicine Global Summit in India in August 2023, after being invited to serve as a member of the Summit External Advisory Group for the WHO Traditional Medicine Global Summit (‘Advisory Group’).

The appointment of Prof Nyoni, who is the current Chairperson of the Board of Directors for the Africa Interprofessional Education Network (AfrIPEN), and Deputy Chair of the Board for Interprofessional.Global – a global confederation of interprofessional networks based in the Netherlands – will be effective for two years.

The WHO Academy is a priority initiative of the WHO transformation agenda and will support accelerated learning and skills recognition of staff and external stakeholders to advance the implementation of the WHO's strategic plan and ‘triple billion’ goal: ensuring that by 2023, an additional one billion people benefit from universal health coverage; one billion more are afforded better protection in health emergencies, and one billion more enjoy improved health and well-being.

Work and contribution being recognised

“I feel thrilled about this exciting adventure. I think this is an exciting opportunity in my career to be recognised by an organisation such as the WHO to serve in the capacity of adviser. I think this is a huge feather in my cap, our School of Nursing, and the faculty. My work and contribution are being recognised and this is a good thing. I am hoping to make an impact in this committee and to also learn from it,” says Prof Nyoni.

Even though there is a bit of pressure representing the whole continent, Prof Nyoni believes his experience with global organisations will come in handy. He is ready to take on the challenge, give it his best, and leave a legacy of excellence.

“Due to the complexity of health professions education in our context, our different cultural, geographical, and socio-economic issues, it is truly an interesting concept to actually think of representing an entire region. I have worked in and continue to work in many countries in Africa through various research projects and postgraduate students, which gives one some insight into what is happening in the region, but often one needs to know more.”

Global knowledge centre for traditional medicine

For Prof Matsabisa, who is also the chairperson of the WHO Regional Expert Advisory Committee on Traditional Medicine (REACT), it is always thrilling to be recognised by serving in such world bodies.

The WHO Global Centre for Traditional Medicine (WHO-GCTM) was established in 2022 as a global knowledge centre for traditional medicine to harness the potential of traditional medicine from across the world through modern science and technology in order to improve the health of people and the planet.

“I look at myself most of the time and ask myself what I am doing right to be given such recognition globally. I am, however, always ready and prepared to take such responsibilities and challenges. I feel happy and great knowing that my expertise and experience is recognised so far from home. I will do my best and try not to fail anyone. I will give it my all and put my whole heart into this task,” says Prof Matsabisa.

He looks forward to seeing the WHO develop tools and guidelines that will promote the institutionalisation of traditional medicine and to come up with positive resolutions on how to take traditional medicines forward.

World takes traditional medicine seriously

According to Prof Matsabisa, the world is now taking traditional medicines seriously. The developed world is now serious about using traditional medicines for their daily health needs and consumption. The world is accepting the positive and important role that traditional medicine is playing in our health-care needs and how it is contributing to the health and well-being of people.

“It is unfortunate that, at home, we have sceptics and people still living in the past who are blind to the importance of traditional medicines. The WHO is now seriously taking the lead in giving advice and guidelines on traditional medicines. It makes me very happy to see these significant movements around traditional medicines."

Africa, Prof Matsabisa concludes, still has its natural resources and its indigenous knowledge as the main remaining tools to get the continent into development and economic freedom. If strategic decisions could be made around developments based on the natural resources for local beneficiation and moving away from the ‘thinking about resources’ to a knowledge-based economy, we could take the continent out of poverty, famine, and wars, and redirect resources to development, technical skills development, and wealth generation for all.

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.”
