KovsieSport crowns their best
The University of the Free State honoured their best sports achievers on Wednesday night. The major winners are, from the left: Tyler Beling (best junior sportswoman), Raynard van Tonder (best sportsman),Lynique Beneke (best senior sportswoman), and Rynardt van Rensburg (best senior sportsman).

The athletes Rynardt van Rensburg and Lynique Beneke walked away with the two major awards at the KovsieSport honours function on Wednesday 26 August 2018.

The two were announced as the Kovsie Sportsman and Sportswoman of the Year. Both of them represented South Africa at international level in the past 12 months and were the national student champions in their items.

Van Renburg’s major achievement was the 1:45.15 he ran in the 800 m at the Hengelo World Challenge meeting, which is the 32nd fastest time in the world in 2018 and also his personal best. Beneke, among others, earned a bronze medal at the African Senior Championships in the long jump and won the item at the National track and field championships for a sixth consecutive year.

Tyler Beling, another athlete (middle distance), was named the Junior Sportswoman of the Year while cricketer Raynard van Tonder was the best Junior Sportsman. Van Tonder captained the South African team to the U19 Cricket World Cup, where he scored the third most runs at an average of 69.6. Beling is the country’s best junior in the 1 500 m.

Juanelie Meijer, Louzanne Coetzee (athletics), and Johann van Heerden (swimming) received special awards for their achievements as athletes with a disability.

Other nominees on the night were:

Senior Sportsman of the Year: Ox Nche (rugby).

Senior Sportswoman of the Year: Kesa Molotsane, Ts’epang Sello, Yolandi Stander (all athletics), Khanyisa Chawane, and Meagan Roux (both netball).

Junior Sportsman of the Year: Pakiso Mthembu (athletics), Lubabalo Dobela, and Rewan Kruger (both rugby).

Junior Sportswoman of the Year: Casey-Jean Botha (hockey) and Michaéla Wright (athletics).

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.
