University of the Free State (UFS) Alumni may be based all around the world, but the United Kingdom (UK) Alumni Chapter aims to reconnect with all those members.

The UK Chapter is a hub of a developing UFS international programme. “We want to provide an opportunity for alumni to share their university experiences with wider audiences,” explains Carmenita Redcliffe Paul, Assistant Director: Alumni Relations and Business Development at the UFS.

Platform to celebrate successes

“The programme aims to provide a platform to alumni to celebrate their successes and provide a window to the landscape of the life and times of the university and the people who shaped it.”

“We also want to celebrate the diversity of our former students and the many touchpoints which unite them.”

Two key projects, Global Citizen and Voices from the Free State, came to life as a result of the collective collaboration of this chapter. The Global Citizen invites people in a series of “courageous conversations” to rethink their relationship with the world. Voices from the Free State is a series of personal podcast narratives by outstanding alumni wherein they reflect their experiences at the UFS. They tell their stories and explain how their university years shaped their future and paved the way to their respective successes.

Relevant association with the UFS

“Furthermore, they motivate why their ongoing association with the UFS is still relevant and important,” says Redcliffe Paul.

The UK Alumni Chapter is led by alumni Francois van Schalkwyk and Keenan Carelse and supported by Adrienne Hall.

Redcliffe Paul says Carelse and Van Schalkwyk have been instrumental in the Voices from the Free State initiative as they are strategically and operationally invested. They create and co-host the podcast series.

Van Schalkwyk is an entrepreneur and innovator consulting with clients globally. Carelse is employed in the healthcare sector in the UK.

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.
