SADoCoL
Betsie Human and Elandré Williams, analysts at the South African Doping Control Laboratory (SADoCoL) at the University of the Free State (UFS), will be involved in sample preparation, analysis and data processing at the upcoming Olympic and Paralympic Games in Paris, France.

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.”

Heart-valve studies receive international recognition

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
