“May the best team win the 2019 BestMed Pedometer Challenge!” said LJ van Zyl, Pedometer Challenge ambassador.

Participants in the 2019 BestMed Pedometer Challenge will start improving their health step by step after the University of the Free State (UFS) challenged the Stellenbosch University, Central University of Technology, and North-West University (NWU) to an eight-week walking competition.

South African 400-metre hurdles record-holder and the Pedometer Challenge ambassador, LJ van Zyl, embraced the initiative as an alternative method to achieve fitness. “I am so tired of running and this is great way to stay fit,” he said during the official launch on the UFS Bloemfontein Campus on 5 April 2019.

Inter-institutional fight for fitness

Last year, the UFS Division for Organisational Development and Employment Wellness in the Department of Human Resources led a UFS-only challenge that saw 60 teams of staff members log a total of 54 606 km in eight weeks. The division then challenged the NWU.

Together, the NWU and UFS walked 132 000 km. This year, the UFS is taking it one step further by challenging two more institutions.
  
Leading the way

“We aim to get South Africa active – starting with the UFS – by embracing fitness and health ourselves,” said Arina Engelbrecht, UFS Employee Wellness Specialist.

Participants on all fitness and activity levels will gun for a 200 000 km target over 10 weeks.

The challenge kicked off on the Bloemfontein Campus with a 3-km walk at the launch, leaving 199 997 km between the four universities for the rest of the eight-week challenge.

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.
