Systems, processes, and policies are not exactly things that grab the headlines or are popular topics for dinner conversations. But they become vital in times of crisis. 
And if there is one thing that we have learnt from the COVID-19 pandemic, it is that no amount of time, effort or resources should be spared to get them in place before disaster strikes, says Prof Francis Petersen.

During my own education and training in the field of engineering, I was constantly reminded of the value of systems: a set of components working together as parts of a mechanism or an interconnecting network; a complex whole. In subsequent years, I also realised time and time again how system principles can be applied equally successfully in management. In any organisation, systems ensure unified and stable operation. And in times of crisis, they prevent hysteria, uncertainty, and unnecessary waste of time.

Lessons learned in reaction to the pandemic

At the University of the Free State (UFS), we quickly learned the value of acting proactively when it comes to the COVID-19 pandemic, as well as getting sustainable systems in place that operated in unity. Amid all the uncertainty and change, we found that it was vital not to re-act in a knee-jerk manner and steered away from implementing random measures that did not consider the entire institution, its history (how it grew and developed up to this point in time), and its future (the altered, post-COVID-19 landscape).

Early reaction and a sustained focus on the period after the pandemic, characterised our response action. A UFS COVID-19 Task Team was already formed at the end of February 2020, as news of the first infections trickled in from Wuhan, China.

When the first South African COVID-19 infection was reported on 5 March 2020, a Special Executive Group moved into action. It had several focus areas: Teaching and Learning, Staff, Operations, Re-integration of Staff and Students on Campus, Finance, Risk and Legal, COVID-19 Science, and Future Thinking. We immediately began the migration to remote teaching and learning, which involved the training of staff, getting the material online, briefing students, procuring laptops, and zero rating the learning portals.

In mid-March 2020, staff who were able to, were asked to work from home. Events were postponed, staff and students were trained to work in a remote setting, and a moratorium was placed on international travel – even before a national lockdown was put in place by government.

In retrospect, this timely, holistic, systematic approach proved to be invaluable.

Learning from a global system

The pandemic also reinforced the lesson that no country is an island. We should learn from others, not repeat their mistakes, and not ignore their successes.

A successful system never operates in isolation, but is affected by, and has an influence on the systems around it.

As we are entering the vaccine phase of the pandemic, it is more vital than ever to maintain a ‘systems’ approach.  Now is not the time for shortcuts, untested remedies, and vague claims of efficiency. Now is the time for systematic implementation of tried and tested processes, developed over time and underscored by good science.

Our part in the vaccine production system

At the UFS, we are privileged to play a role on two important fronts: 

The South African National Control Laboratory for Biological Products (NCLBP) located on our Bloemfontein Campus, is performing the all-important task of vaccine-lot release. As the sole provider of this service in the country and one of only twelve World Health Organisation (WHO)-contracted laboratories worldwide for vaccine quality-control testing, it forms part of a carefully crafted regulatory system, which has been established, fine-tuned, and tested over many years to serve the interests of the global community.

Vaccines are biological medicines and some of the most complex pharmaceuticals available today. It is vital that their regulation be governed by scientific and not commercial or political principles. It is a role that should under no circumstances simply be given to the ‘lowest bidder’ or the one who promises ‘speedy delivery’.

The NCLBP did not get to play this regulatory role overnight. It was already established in 1997 after an extremely stringent audit by the National Regulatory Authority (NRA) and subsequent recommendations by the WHO.

This means that all its operations – from the way documents are compiled and stored, to the maintenance of equipment and infrastructure, as well as staff competency – are performed according to strict international guidelines and are continuously and closely monitored.

It forms part of an involved system with checks and balances in place to ensure that no mistakes are made. 

Similarly, FARMOVS – a wholly owned clinical research company of the UFS, together with several medical and scientific experts at the university –  has submitted a clinical trial protocol for approval to the South African Health Products Regulatory Authority (SAHPRA) to determine the efficacy of Ivermectin for COVID-19.
FARMOVS was systematically prepared and shaped for this role, having been involved in countless pharmaceutical trials, proving its own efficacy consistently over a protracted period.
Not only is it the only onsite ISO- (International Organisation for Standardisation) and GLP- (Good Laboratory Practice) certified bioanalytical laboratory on the African continent – it has continuously proven itself to adhere to the most rigorous international requirements over the past 47 years.   

It is extremely satisfying – and reassuring – to see how institutions like these two, rooted in sound science, and having proven their consistency, efficiency, and accuracy over many years, are now stepping up to the plate and performing the all-important functions for which they were painstakingly and systematically designed. 

‘Vaccine nationalism’

This pandemic has shown that, through the interconnectedness of our world, one country or region has an impact (in this particular case a health-impact) on other countries and regions. In this context, it is up to rich countries to ensure fair and equitable access to vaccines for poorer countries, and that the WHO proposal to request pharmaceutical companies to waive their intellectual property rights in this regard, should be supported. 

‘Good science’ more important than ever

Another thing the pandemic has highlighted, is the importance of good, sound science amid all the hype, speculation, and false news that unfortunately also characterise the COVID-19 era. 

The co-incidental meteoric rise in the popularity of social media has fuelled the fire of unverified and unscientific claims that are so often just lapped up by information consumers in the public sphere. Unfortunately, since we have entered the vaccine phase, this has become increasingly rife. 

Here, the role of universities as education and research facilities is becoming more important than ever. Not only do we need to provide and communicate the ‘good science’ that everyone craves. But instead of simply advising from the side-line, we should also be playing a vital practical role, actively applying our knowledge, resources, and expertise within the broader society we serve, as has been aptly demonstrated in our important role of vaccine regulating.

Role of universities in the post-pandemic era

Without a doubt, the pandemic has highlighted the importance of online learning, the huge need that exists to be properly equipped for this and has given us a powerful shove in a direction we were already advancing to.

But it has also shown us that, in the midst of increasing digitisation, our need for social and physical interaction remains. The isolation brought about by COVID-19 has taught us that we cannot only function as a digital society. This will probably lead to higher-education institutions presenting a blended mode of learning and teaching in the future; a combination of online learning and face-to-face interactions, ensuring that students still get to experience campus life and the valuable interactions that go with it. 

The pandemic has also helped to crystalise the way in which we as ‘generators of knowledge’ should interact with society. The recent rhetoric of anti-scientific world leaders has caused communities to become distrustful of universities and science. 

We need to actively work on building trust within communities again. And we can only do this by working closely with other sectors of society, gauging real needs, and working together as parts of a bigger system in order to find real, practical solutions that can be seen by everyone to make a positive change in different spheres of society. 

Every organisation, business, government, and institution benefit from having both visionaries and pragmatists.  The visionaries help us to imagine a future we want to live in. The pragmatists work out practical, doable, and sustainable steps to get there. 

Sometimes it becomes necessary for the activists and orators to step aside and create space for the scientists and administrators to systematically get on with what needs to be done.
While we are all eager to move beyond this period in our collective history, back to a world that resembles more of the ‘old normal’ we long for, we should not make hasty, ill-considered moves and take shortcuts to get there.

We should also see this period as our opportunity to push our boundaries, embrace the ‘new normal’, and be innovative in our thinking on how to stay there.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
