According to the international market and consumer data company Statista’s June 2022 data, more than 4,6 billion people worldwide are using social media; this is an increase of 1 billion people compared to the total users in 2020. 

Delivering his lecture on ‘Social Media, Freedom of Expression, and the Law’ on the University of the Free State Bloemfontein Campus on 30 May 2022, John Jeffery, Deputy Minister of Justice and Constitutional Development, said, “The power of social media lies in the sheer magnitude of the number of people using it.”

He said: “Section 16 of the South African Constitution provides that everyone has the right to freedom of expression, which includes freedom of the press and other media; freedom to receive or impart information or ideas; freedom of artistic creativity; and academic freedom and freedom of scientific research.”

He advised perpetrators of malicious social media posts about the consequences and the harm to persons who are victims.

Depending on the circumstances, a person who suffers harm because of being the subject of someone else’s social media posts, can be protected under the Protection from Harassment Act. According to the Act, this is due to mental, psychological, physical, or economic harm.

Speaking at the Odeion School of Music, Deputy Minister Jeffery said, “Social media brings with it the importance of responsible use. As a social media user, you are entirely responsible for whatever appears on your social media accounts.’

He said: “Whatever you do in life – your conduct and your words – can be put onto various platforms and they will be there for a very long time. Do better, be better – and use social media to inspire people, to have an impact on the world, and to make it a better place.”

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.
