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.”

Childhood obesity should be curbed early

Serious intervention by parents is required to deal
with childhood obesity. Prof Louise van den Berg and

about the prevalence of obesity in six-year-olds in

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.

Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.

Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.

Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.

Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.

The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.

A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.

The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.

When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.

Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.

At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.

The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
