Keabetswe Malebo was recipient to the scholarship by Abbe Levin.

Great stories are often the result of unexpected connections made across time and space. Upon looking back and connecting dots, one is often surprised at how seemingly random events lead to happy endings, which in themselves become beginnings for new stories.

Leaving a legacy

When Ida Manana Siyila left South Africa in the first half of the twentieth century, no one would have known how her legacy would influence a young student at the UFS many years later. While working for the same American family for more than 30 years, she never stopped learning and working to improve herself. Ida, proud of her dual citizenship, never lost contact with her friends and family in Bloemfontein, wishing to return to Bloemfontein in her old age. Her American family made sure that this wish was fulfilled.

For Keabetswe Malebo, the first six months as a student were tough. An energetic young lady with joy in her voice and a passion for learning and making a difference in her community, Keabetswe had been squatting with a friend while studying at the UFS. The friend was running out of money; there was no way Keabetswe could pay her debt, and her friend could not afford the rent. No rent, no accommodation. No accommodation, no further studies.

Changing a life

Abbe Levin was sincerely grateful for what Ida Siyila had done for her family. In 2017, Abbe made a donation to the UFS requesting that it be used as a scholarship for a disadvantaged student in Ida’s name.

When Keabetswe read about the scholarship, she applied. “I felt it was for me, I was so excited and afraid.” Keabetswe’ s belief, commitment, and hard work were rewarded when she was granted the scholarship. “I got the money just in time to buy a laptop, a printer, and a microwave … and of course to pay the rent I owed my friend.”

Since then, Keabetswe has met Abbe Levin online, and they have become friends, communicating, sharing family pictures and stories, ever grateful for the never-ending story of Ida Manana Siyila.

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.
