“Being a humanitarian cost you absolutely nothing.” – Precious Lesupi

University of the Free State (UFS) second-year BA Journalism student, Precious Lesupi from Kanana in the North-West, is a self-proclaimed ‘lover of people.’ She chose to spend her 21st birthday with disadvantaged children afflicted by life-threatening and life-limiting conditions at Bloemfontein’s Sunflower Children’s Hospice.  

Precious explains that her self-developed and coordinated charity and donation drive dubbed ‘Sunflower’s 21st’, was born in commemoration of her father who passed away after suffering from cancer. Her donation drive is aimed at catering for the medical needs of children battling chronic and terminal illnesses, such as cancer. The campaign will run until 2 November 2019, which marks this year's International Children's Day.

Her own personal experiences with genetic illnesses and diseases have been severely trying. But she believes her different life experiences and her family orientation have helped to shape her into being the vibrant, empathetic, philanthropic, and strong-willed young woman she is today.

Her goal is to continue initiating positive, life-enriching experiences for the less fortunate – especially children. 

Precious simultaneously drove another campaign alongside Sunflower’s 21st, called the Winter Jacket Challenge, which aimed to provide the homeless with jackets and warm clothing for winter. 

The embodiment of a clear benevolent spirit that burns to create positive memories and experiences for the less fortunate.

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.
