SADoCoL staff members off to the Olympic and Paralympic Games

18 June 2024 | Story André Damons | Photo Suplied

Two staff members from the South African Doping Control Laboratory (SADoCoL) which is housed at the University of the Free State (UFS), have been selected to work at the upcoming Olympic and Paralympic Games, in Paris, France.

Elandré Williams and Betsie Human will support the Paris laboratory during both games. The Olympic Games will take place from 26 July to 11 August 2024 and the Paralympic Games from 28 August to 8 September 2024.

Williams will be involved in steroid profile analysis, which includes sample preparation, analysis and data processing by Gas Chromatography (GC) and Isotope Ratio Mass Spectrometry (GC-C-IRMS).

Part of the fight against doping

“I am excited, optimistic and privileged to have been given this opportunity, but I have to say that I am also quite nervous as this is most probably the biggest sporting event of the year. Being a part of the fight against doping in sport remains a great responsibility as what we do directly impacts the athletes,” says Williams.

She says is looking forward to the entire experience, from doing what she loves on an international level, meeting other analysts in the field and being part of the fight against doping in sport on an Olympic level.

This is her first big international sporting event.

“I am also looking forward to learning from other experts in the field who have more experience and to witness the procedures and the manner in which the laboratory operates at this time where the sample numbers are extremely high with the added pressure to finalise results in short turn-around times. This is a great opportunity for growth, both individually and in my field of expertise, in the scientific and the doping control field.

“It will definitely be an advantage for me as an analyst to get exposure to how the entire analytical procedure is executed in another laboratory, as well as insight into possible new techniques and advancements that I will be able to apply back at SADoCoL. I also think this is a great way to improve my ideas, perspectives and level of expertise as I will be working and witnessing other scientific experts in the doping control field.”

Managing workflow and logistics at the Games

Human, who was an analyst at the 2010 Soccer World Cup in South Africa, says she is both nervous and excited for this experience.

“I was a junior analyst at SADoCoL during the 2010 Soccer World Cup, but you cannot compare a single-sport discipline with a multisport discipline like the Olympic Games – The Games will be exponentially bigger.

“In the past 14 years doping control as a whole has grown significantly. New technologies, updated requirements, more sensitive testing methods have emerged – this will be a new experience,” says Human.

She will also be involved with sample preparation/analysis/data processing and says she is looking forward to seeing how the work-flow and logistics associated with the Games (massive amounts of samples/tight deadlines etc) is managed in a high through-put laboratory.

“I am of course also looking forward to meeting analysts from other labs – we are a bit secluded here at the southern tip of Africa. Collaboration between labs is tricky when your closest neighbour is in Europe.

“It is always eye-opening to see how other labs manage similar situations (even though an Olympics is quite different from normal routine days) – exposure to new techniques and alternative thinking has a way of elevating your own thought processes and it promotes growth – both as an individual and as a doping control analyst.”

Immensely proud

Hanno du Preez, Director of SADoCoL, says the laboratory personnel are immensely proud that two of their staff members were chosen to participate in this international event, which for many scientists is the peak of their career. Similarly, this provides acknowledgement to the staff members for the area in which they have been working.

“It is only a select few who are requested to provide service at the Olympic Games. The work conducted in an Olympic laboratory provides experience which cannot be gained elsewhere. The workload and fast-paced analysis is something which the personnel are used to, but the Olympics will bring a different dimension to the processes.

“We are excited to see what Betsie and Elandré bring back, with regards to new viewpoints on processes which are similar in all anti-doping laboratories. Individual experiences uplift everyone in a regulated business unit such as SADoCoL and also ensures improved relationships between laboratories, as other anti-doping laboratories will be represented at the Games as well. We wish them all the best for the experience, and we thank them for being dedicated ambassadors for SADoCoL and the UFS.”

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.”
