The Cardiac Simulation lab in action

There’s an electric atmosphere in the operating theatre of the Faculty of Health Sciences, as Dr Taha Gwila and his team focus with intense concentration on the fleshy exposed heart beating rhythmically in the opened chest of the patient lying in front of them. The enormous demands of open-heart surgery are evident to everyone looking on. But there’s a catch. 

The patient is faceless and rubberised. The red liquid flowing in the pipes that network from the body is not blood. And the pulsating heart was beating in the body of a pig not too long ago. 

Cutting edge technology
 
This Cardiac Simulation laboratory supplied by Medtronic is the newest addition to the School of Biomedical Sciences’ clinical simulation and skills unit. 

“There’s nothing like this in Africa, and only a few in the world,” says a beaming Prof Francis Smit, Head of Cardiothoracic Surgery at the Faculty of Health Sciences.
He explains that this new cutting edge medical technology will revolutionise the way cardiac surgeons and other health professionals are trained and assessed.

Practicing specific procedures

The simulation facilities give students with various levels of competency the opportunity to practice specific procedures in their own time and at their own pace.
“Traditionally training followed the apprentice model, where surgeons started with simple tasks and worked their way up. They assisted senior personnel and their exposure to procedures depended on the conditions presented by the patients before them,” explains Prof Smit.

The simulation technology now enables them to repeatedly practise a certain procedure without any risk to a patient. A sophisticated electronic grading system gives detailed feedback after each session, so they know in which areas to improve.  

Simulated emergencies

The system also allows trainers to create a medical emergency that the trainees then have to deal with.

“Assisting senior surgeons with high levels of competency means that in the past, trainees would often never get the chance to experience these kinds of complications during operating procedures. Now we give them a chance to build that confidence so they’ll be able to handle different situations.”  

Training hub for Africa
 

The UFS cardiothoracic programme is being designed to become a training hub for the whole of Southern Africa, combining distance learning with an on-site high-fidelity simulation and assessment centre.

“This is 100% real!” says an excited Dr Gwila after successfully completing his first simulation session. “As a Senior Registrar at the Cardiothoracic Department I’ve done similar procedures on real patients and there’s really no difference at all. Every registrar should do this before ever touching a real body.”

Plant eco-physiologist finds effective solutions for crop optimisation

The bio-stimulant was tested on
this citrus. This is the first time
that the product has been tested
on a crop.

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
