Khanyisa Chawane, a Protea player, should be one of the stars for the Free State Crinums in the Telkom Netball League. She was the Player of the League in 2018.

Having to play 11 matches in so many days before the knockout stage will be a daunting task, but their fitness levels are up to standard, says the coach of the Free State netball team. Burta de Kock of KovsieSport will again guide the Free State Crinums in the Telkom Netball League, which will be taking place between 14 and 27 October in Bloemfontein.

All but one of the 12 members of the team are studying at the University of the Free State (UFS).

“Planning will be of the utmost importance to manage the load on the players. We also have four players (Rolene Streutker, Chanel Vrey, Boitumelo Mahloko, and Refiloe Nketsa) who will participate in the South African U21 team that will play five invitational matches during the competition,” said De Kock.

In previous years, the competition took place over four to six weeks, but now it had to be fitted into two weeks due to COVID-19.

“So, it will be a tall order to play so many matches, but an exciting challenge. I believe the hard work the players had put in during the lockdown period will bear fruit. They were exceptional and very determined to stay in shape.”

The Crinums won the first three years of the competition, but couldn’t reach the final in the following three years. Apart from the 11 Kovsies in the Crinums team, there are 9 current or former UFS students in other teams participating in the league. 

They are Zandré Smit, Bianca Pienaar, Dané Klopper, Arné Fourie, Bethenie du Raan (all Northern Cape Diamonds), Maryke Coetzee, Danelle van der Heever (both Mpumalanga Sunbirds), Rieze Straeuli (Western Cape Tornados), and Alicia Puren (KZN Kingdom Stars).

The Crinums team: Boitumelo Mahloko, Ané Retief, Jana Scholtz, Khanyisa Chawane, Lefébre Rademan (captain), Sikholiwe Mdletshe, Claudia van den Berg, Bianca de Wee, Rolene Streutker, Chanel Vrey, Lerato Chabwe, and Refiloe Nketsa.

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.
