Former Bok gives back to his alma mater

After a long and stellar career as a rugby player, Wian du Preez felt it would be unfair not to give something back to the game that had treated him so well.

Du Preez has been appointed as the new head coach of the Shimlas U-20 team, better known as the Kovsie Young Guns. They participate in the Varsity Young Guns competition.

Former Springbok
The 35-year-old Du Preez, a former Springbok, retired in 2016. He now works as a financial advisor at Jenwil BlueStar Financial  Advisory Services in Bloemfontein.

“Making the step from a professional rugby player to the corporate world was a difficult one. Thus, coaching provides me with the opportunity to stay involved in the game and to get out of the office.

Giving back
“I thought it would be nice to give something back after receiving so much from rugby. Having the opportunity to work with youngsters, you can help shape them for a career in rugby, should that be something they aspire to.”

Du Preez is a former Shimla himself, having worn the blue jersey between 2002 and 2004 whilst studying for his BCom (Investment Management and Banking).

Both his parents work at the university. His mother, Lizette, is semi-retired, but still acts as part-time assistant at the Department of Afrikaans and Dutch, German and French.

His father, Prof Chris du Preez, was the head of the Department of Soil, Crop and Climate Sciences and was a lecturer. In his final year before he goes on pension, he assists postgraduates with their studies.

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.
