“I believe the Hesselbein Global Academy annual fellowship programme was vital for me as a potential public servant of South Africa to serve the people of this country in government one day.” – Kofi Yinkah

University of the Free State (UFS) third-year BAdmin student, Kofi Annan Yinkah, formed part of the Hesselbein Global Academy annual fellowship programme, hosted by the University of Pittsburgh in the United States of America (USA). Originally from the East Rand in Johannesburg, Kofi represented the UFS as one of the top-50 students who were selected out of 450 global applicants.

The Hesselbein Global Academy annual fellowship programme aims to connect young leaders from all over the world with well-equipped professionals who are leaders in the fields of business, government, and education. This programme was established for the purpose of cultivating and producing cadres who will become experienced ethical leaders, armed and qualified enough to address and solicit solutions for critical issues experienced by diverse societies throughout the world.

“The fellowship covered topics that have helped to broaden my critical thought processes and concerns about societal issues in our country and all over the world. It has also emphasised the importance of implementing change through effective governing-policy development and establishment,” Kofi says.

He describes his experience at the fellowship as “out of the ordinary,” and believes that it has had a progressive influence on his life. He explains how it has unlocked his mind through enlightened engagement with student leaders from various countries in the world, including Nigeria, England, Canada, Chile, Trinidad and Tobago, Vietnam, China, United States of America, and Ireland.

One of the most important tools he believes his experience has equipped him with, is understanding the significance of employing a solution-driven approach to various situations. He is confident that this will give him the necessary skills and knowledge to work effectively in teams.

Kofi explains that he found out about the fellowship programme via social media. He encourages UFS students to use online platforms to source information about opportunities that can offer them meaningful experiences for learning and growing.

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.
