Besides being the top medical student at UFS in 2021, Dr Mario Vieira is passionate about food, music and sport, and plays the piano and guitar for leisure.

Dr Mario Vieira, one of the University of the Free State’s (UFS) newest graduates in the MBChB programme, says he is fortunate and blessed to graduate from the Faculty of Health Sciences as the top achiever in the class of 2021. Dr Vieira will graduate at the year-end ceremonies. 

Says Dr Vieira: “Privileged is the first word that comes to mind. Yet, there are so many other emotions and feelings involved. One is relieved that the hard work is over for now, but in the same breath, quite sad that this chapter of one’s life has come to an end. Excitement also comes through, knowing that a new challenge lies ahead.” 

Dr Vieira says being the top achiever is undeniably an unbelievable achievement, but there were many other factors and people who made it possible. His family, especially his parents, were his greatest motivation. Their unconditional love and support have made his success possible. 

Multiple factors led to medicine 

According to Dr Vieira, who wanted to be a pilot when he was growing up, there were multiple factors that led to him eventually study medicine. He says: “My first experience with medicine was at a young age when I lost a good friend of mine to cancer. I believe the seed that was planted began to grow when my brother started studying medicine. 
“In high school I made the decision once I realised I was passionate about people and would love to make a difference in the life of others. I think it was the idea that if one could pass this degree, one would be equipped and capable to change lives on a daily basis. My friends in medicine and the support system in Bloemfontein were also incredibly valuable. When times were tough, we would carry each other through,” says Dr Vieira on graduating in one of the university’s toughest fields.

He is starting his internship on 1 January 2022 at Addington Hospital in Durban. 

Besides medicine, this Bothaville, Free State native is also passionate about food, music and sport. He loves cooking and hopes to retire one day with a small restaurant by the sea – cooking food and putting smiles on people’s faces. He also loves playing piano and the guitar.

His message to other students who might be considering studying medicine is: “Be courageous. You are capable of more than you think. Believe in yourself. Hard work, determination and time management can get you where you want to be.” 

Your courage 

Prof Lynette van der Merwe, who took up her new position as Academic Head in the Division Health Sciences Education, Faculty of Health Sciences on 1 December 2021, congratulated the new cohort of UFS doctors and reminded them of the three Cs in the MBChB programme in 2021 – courage, conviction and compassion.

 “I saw your courage, the way you squared your shoulders and looked personal, academic and financial problems in the eye, and endured. You were brave and strong when it mattered most. and stayed true to yourself despite overwhelming odds. You made good choices although they were hard, you found a way to put one foot in front of the other when you were too tired to even think.”

“In the words of the poet Amanda Gorman, “There is always light, if only we’re brave enough to see it. If only we’re brave enough to be it. May you always carry your light into a dark world.”

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
