Christina Mack – believes in praying for communities.

Leaving Rustenburg in the North-West for the Free State, Christina Mack’s life has changed for the better. Mack, a Housekeeping Manager on the University of the Free State (UFS) Bloemfontein Campus, believes in hard work and honesty – these are the principles she has lived by for many years. 

“I was fortunate to get a job as a cleaner at the university in 2006, a position I held until I was promoted to Housekeeping Manager in 2016.

“I believe in myself; I am a hard worker and because I am a manager, I always strive for honesty. When I have a challenging day – especially at work, I engage with colleagues with honesty.”

One of the many UFS women of quality, impact, and care, Mack says she is living the life she imagined through some powerful life lessons.  

“I have learnt that in life, you must appreciate everything that is good, have a vision, focus on education, and know your position. You must not only pray for yourself, but also for your community.”

Women who inspire her include her Line Manager, Ronell Kruger. “She encourages and supports me, and she is a hardworking woman. Ronell motivates her staff. In the team, she is a mentor and supports all of us.”

What worries her is the continued and high number of gender-based violence cases across the country. “Government should create platforms for men to be taught about taking care of women. Women deserve equal rights to their male counterparts.”

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.
