Dr Nicholas Pearce, Head of the COVID-19 Task Team at the Universitas Academic Hospital, leads a dedicated team of professionals at the testing and vaccination site of the Universitas Academic Hospital, adjacent to our Bloemfontein Campus.

It is impossible to quantify the number of hours Dr Nicholas Pearce, Head of the COVID-19 Task Team for the Universitas Academic Hospital, spent working in response to this deadly virus since the first case was reported in South Africa last year. 

According to Dr Pearce, who is the Head of the Department of General Surgery in the Faculty of Health Sciences at the University of the Free State (UFS), the initial preparation phase required many hours of brainstorming, planning, and physical hours working on site. He also spent countless hours awake at night trying to come up with solutions for the many challenges faced along the way. This is in addition to being available telephonically twenty-four-seven for any issues related to equipment, staffing, and facilities.

“I was attending a vascular surgery congress in Germany last year January (2020) when China just announced the outbreak of COVID-19. I noticed an increased number of travellers wearing surgical masks at an airport in the Middle East when I was travelling to South Africa. 

“Upon my return to work, I approached management to discuss procurement of PPEs, as it was just a matter of time before COVID-19 would hit South Africa and the rest of the world. When things escalated, I was asked to head the COVID-19 response team at Universitas Hospital,” explains Dr Pearce.

Dr Pearce, who was brought up to always strive to be better, is driven and motivated to succeed. He has a very analytical brain and loves challenges. In fact, he does not believe in problems and only sees challenges. This kind human being can sometimes seem quite tough on the outside, but actually has a very soft heart. 

“I think it is human nature to want to feel needed. I have an inherent urge to help my fellow human beings. This is also the reason why I became a health-care professional and why I am passionate about teaching,” says Dr Pearce. 

With South Africa lagging behind with its vaccination programme, the hard work is far from over for Dr Pearce and his team. Says Dr Pearce: “The initiation of a mass vaccination site posed a whole new set of challenges, which once again required many hours of planning. The initial stages of running the vaccination site required many hours of physical hard work a day. Then there is also the daily operations meeting at 18:00 every weekday to discuss the vaccine roll-out in the province.”

Frustrations and setbacks

For Dr Pearce, this pandemic highlighted the differences between individuals from different social classes in our country. Providing quarantine and self-isolation facilities for individuals who do not have access to such facilities at home is one such example. 

“We all have a right to clean water and good quality healthcare. This also includes a right to oxygen. This right to oxygen has proved to be one of our great challenges in managing this pandemic. Delivery of these large amounts of oxygen has been especially challenging. Some days we require in excess of five tons of oxygen,” says Dr Pearce.

There have been many frustrations and setbacks on this journey, some of which can be quite demoralising and demotivating, but knowing that he is doing something good for his fellow human beings gives this gentle and diligent healthcare worker a tremendous amount of energy. “Positive feedback from patients and colleagues far outshines all the frustrations and disappointments,” concludes Dr Pearce. 


Outside of work

After finishing online meetings at home, Dr Pearce relaxes with his partner by chatting about the day’s events and cooking supper together while enjoying a glass of wine. He also tries to connect with family who lives in Gauteng. Because of work pressures and the pandemic, he has not been able to see them as much.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
