Dr Osayande Evbuomwan, a Senior Lecturer and Medical Specialist in the Department of Nuclear Medicine, always wanted to specialise in an area of medicine that was novel, innovative, intriguing and involved a lot of opportunities for groundbreaking research

Dr Osayande Evbuomwan, Senior Lecturer and Medical Specialist in the Department of Nuclear Medicine, Faculty of Health Sciences, at the University of the Free State (UFS) always wanted to specialize in an area of medicine that was novel, innovative, intriguing and involved many opportunities for groundbreaking research.

This passionate medical man, who joined the UFS in 2019, is behind his department using Lutetium 177 PSMA (Lu-177 PSMA) therapy to treatment metastatic castrate resistant prostate cancer (MCRPC) – an advanced stage prostate cancer. 
The UFS and the Free State province can now join other South African universities, like the University of Pretoria, University of the Witwatersrand, and other provinces in using this method to treat MCRPC patients. 

Built for this job

Dr Evbuomwan explains nuclear medicine is a medical specialty that involves the use of unsealed sources of radiation in the form of radioisotopes for the diagnosis and treatment of various disease conditions including cancers.
“It’s novelty and opportunity for research and ability to diagnose and treat disease conditions in one specialty attracted me to this field. I always wanted to be a doctor. I see it as a calling. It was also something my mum discovered while I was growing up as a child. In my next life, I would choose to be a medical doctor again,” he says.

“I was built for this job and it is always my joy to have the opportunity to carry out my work. We have been well-trained for this; we support all our skills with prayers. We try to give our patients the very best,” says Dr Evbuomwan, who is originally from Benin City, Edo state, Nigeria. 

After graduating as a nuclear medicine specialist from Wits University, Dr Evbuomwan moved to the City of Roses after a work opportunity opened. He saw it as an opportunity to showcase his talents.

“I have been privileged to receive training in this treatment during my residency training at Wits. I treated a few of these patients during my training and the results were amazing. The University of Pretoria has also been involved with this treatment, with some amazing results that are recognised worldwide. 

“This was enough to convince me to push for our department to also join the powerhouses and offer this treatment to patients who need it. With the influence of a very understanding head of department, Dr Gerrit Engelbrecht, we have been successful in pushing for the commencement of this treatment at our facility,” says Dr Evbuomwan.

Important treatment
According to him, the availability and expertise of Lutetium 177 PSMA (Lu-177 PSMA) therapy to treat MCRPC is very important for the Free State and the UFS, as it is able to offer an option for patients who do not qualify for available conventional treatment and/or who have failed the first line of conventional treatment. 

“In the majority of patients this treatment offers improved quality of life, disease-free progression and improved overall survival. It also alleviates the constant bone pains these patients have to go through daily. To be able to offer this treatment puts the university and the province on the map alongside other top institutions in and outside the country. It also offers opportunity for research,” says Dr Evbuomwan.

He believes with a PET/CT camera for proper staging of these patients with cancer the UFS would be able to expand the treatment of patients suffering from this deadly illness. Currently the university does not possess such a camera and has to use lesser methods in identifying the right patients for this therapy.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
