Qwaqwa Campus

The entrance gate to the Qwaqwa Campus of the University of the Free State (UFS) was blocked by a group of students this morning. The group stoned private security guards, entered the campus, vandalised and looted property, and assaulted staff and students on campus.

Two students were arrested by the South African Police Service (SAPS) and more have been identified; the necessary disciplinary action will be taken, and immediate suspensions will be instituted. Similarly, the SAPS will institute criminal charges against those who have been identified.

The university management has ordered an urgent investigation into today's incident and condemns the destructive behaviour of the group. This behaviour is not viewed as protest action, but as criminal acts.

Any violence and criminal acts against staff and students and the disruption of academic activities are condemned in the strongest terms.

The academic programme on the Qwaqwa Campus continues, mostly online for this week, and students will be informed by their faculties about the revised schedule, as well as arrangements regarding tests and assessments scheduled on the campus for this week.

The campus remains open; the university's Protection Services is on high alert and is monitoring the situation on campus closely.

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.
