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.

Kind human being with a soft heart

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.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
