The COVID-19 pandemic has exposed the fracture lines in societies worldwide. South Africa is no different. The poor are less able to protect themselves from the danger posed by the virus. Workers in factories, mines, and the service sector went back to their places of work following the lifting of the strictest lockdown measures, while office workers, typically better paid, can generally work from home. Living conditions in informal settlements make social distancing all but impossible, while the middle class can largely stay at home and stay safe to a much larger extent. With many businesses shutting down, downsizing or rethinking their business models, it is often small and medium, as well as informal sector businesses that are most affected.  

The impact of COVID-19 comes on the back of a society and economy that was already under significant pressure following years of low economic growth and poor government performance. Many commentators have already questioned the social compact South Africans made in the mid-1990s, which marked the end of the apartheid regime. These divisions have become more glaring, with some civil society organisations considering challenging the Minister of Finance’s adjustment budget in the Constitutional Court, because the budget might result in a roll-back of the progressive realisation of the socio-economic rights mandated in the Constitution.

In this first of four webinars, academics from the UFS as well as invited experts reflect on the constitutional commitment South Africans made to one another two and half decades ago. Is it time for a new deal? Should we collectively recommit ourselves to our existing deal? Do we interpret that deal in the same way today as we did more than two decades ago? How does the economic reality we face, particularly in the aftermath of the COVID-19 crisis, affect that deal? What are the economic realities we face, and whose are they? And how should we think about human development in the context of our deal? 

Come and join us from 14:00 to 15:30 on 21 July. 

RSVP to Sibongile Mlotya at MlotyaS@ufs.ac.za no later than 19 July, upon which you will receive a Business for Skype meeting invite.

Speakers:
Prof Danie Brand on ‘New deal’ or collective recommitment? The Constitution under COVID-19 and beyond

Prof Melanie Walker on Human development and the capability approach in COVID-19 times

Prof Lochner Marais on Reflections on continuities and discontinuities after COVID-19

Prof Philippe Burger on Viewing the realisation of socio-economic rights in a post-COVID-19 South Africa through an economic lens

 

Please also mark the following dates in your diaries for the second through fourth Reflection webinars:
Gender Inequalities and Gender-based Violence 28 July 14:00-15:30
The quality of our democracy under COVID-19 and beyond 13 August 14:00-15:30
Urban living post-COVID-19 27 August 14:00-15:30

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.
