When a dream comes true

Lisa Msiza — Lisa Nondumiso Msiza is the first Deaf person from the UFS to receive the prestigious Abe Bailey travel bursary.

Lisa Nondumiso Msiza is the first Deaf person from the UFS to receive the prestigious Abe Bailey Travel Bursary. This second-year student in Linguistics and Sign Language will visit the UK for three weeks, starting late November. Charity Morrison of the Centre for Universal Access and Disability Support (CUADS) will accompany her to interpret for her.

“I want to show through action that Deaf people can do anything. We have the required skills; we can read and write too – just like hearing people can. I would also like to make people aware that the UFS has the facilities to accommodate Deaf people,” says Lisa. Currently, 12 Deaf students are enrolled at this tertiary institution.

This born Johannesburger’s passion for teaching and facilitating Sign Language is contagious. “I want to observe different businesses and programmes in the UK in order to learn how to start projects and develop myself and my community as Deaf people get limited opportunities. I want to teach people on the use, culture and history of Sign Language.”

Lisa describes herself as a kind, understanding, and loving person. As she was born deaf, Sign Language is her home language. Her parents, however, are Zulu and Ndebele speaking. She says that, although Sign Language is different in every language, she quickly adapts and communicates in it as soon as she grasps the structure of the new language.

Being named top achiever (learner) for the 2020 matric class and being crowned in fifth position at the World Deaf Model 2021, Lisa is proof that beauty and brains can co-exist.

“I am passionate about being a teacher, facilitator, or lecturer. I enjoy teaching others sign language so we can communicate more effectively. I love Sign Language and I am always trying to inform people on the importance of learning about Deaf people and to help others understand the nature of language and communication.”

Her future dreams include becoming a lecturer at the UFS or to continue her studies abroad, but only to gain insight and benefit her community. “I want our country to prosper and would like to have every news bulletin interpreted for the Deaf.”

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.
