Prof Stephen Brown, Principal Specialist in the Department of Paediatrics and Child Health in the Faculty of Health Sciences at the University of the Free State (UFS), and his team are taking life-saving medical care to young patients in the rural parts of the Free State.

Paediatric heart specialists hope that an outreach initiative started back in 2016, allowing them to travel to rural areas in the Free State to diagnose heart defects in babies early, would grow and expand to other rural areas and provinces. 

Every year, more than 40 babies in the rural areas of South Africa may die as a result of an undiagnosed heart lesion, because everyone assumes that they have respiratory problems when they actually have critical congenital heart disease – up to 85% of which is curable, says Prof Stephen Brown, Principal Specialist and Head of the Division of Paediatric Cardiology  in the Department of Paediatrics and Child Health in the Faculty of Health Sciences at the University of the Free State (UFS).

Prof Brown, who is also a paediatric cardiologist at the Universitas Academic Hospital, says a life-saving collaboration initiative between the UFS, the Mother and Child Academic Hospital (MACAH) Foundation, and the Discovery Fund started five years ago to help curb the death of young patients due to congenital heart disease, and to make services more accessible to rural communities.

Hundreds of patients seen annually  

“We initiated an outreach programme due to the fact that some patients found it difficult to get transport to our central hospital. Since the Free State is considered rural, there are long distances to travel. Our concept was that we should take the service to grass-roots level to make it more convenient for the parents and caretakers.

“We partnered with MACAH, and since early detection of congenital heart disease makes a big difference, it fits in nicely with MACAH’s first 1 000 days drive. Due to the hard work of Tertia de Bruyn, we were given the opportunity to come into contact with Discovery. Dr Daniel Buys (UFS Department of Paediatrics and Child Health) and Rudolph Pretorius (echocardiography technician) did a lot of the initial paperwork and motivation,” says Prof Brown.  

According to him, a mobile echocardiography apparatus was donated by the Discovery Foundation via MACAH, which is crucial for doing this outreach work. The machine looks like a laptop and can be transported in a carry case.  

“We see between 170 and 250 patients on an annual basis. The service is obviously confined to secondary hospitals, and we started doing the Mofumahadi Manapo Mopeli Hospital in Qwaqwa and the Bongani Regional Hospital in Welkom. It has since expanded to the Dihlabeng Regional Hospital (Bethlehem) and the Pelonomi Secondary Hospital in Bloemfontein. Since initiation in 2020, Pelonomi has seen on average 40 children per month receiving a heart sonar. COVID-19 has had a major impact on our work,” says Prof Brown. 

First 1 000 days in any child’s life determine their trajectory for life

Prof André Venter, Chairman of the MACAH Foundation, says one of the main commitments of the MACAH Foundation in central South Africa is their passionate belief that the first 1 000 days in any child’s life determine their trajectory for life. Says Prof Venter: “We should do everything in our power to ensure that this 1 000-day journey is as optimal for each child, including conception, pregnancy, birth, and health during the first two years of life.”

“As Chairman of the MACAH Foundation, I am sincerely grateful to pioneers such as Prof Brown and his team in Paediatric Cardiology for their excellent outreach initiative, but also to the Discovery Fund who shared our vision and that of Prof Brown’s team and was willing to make this very generous donation. I am so proud of and so grateful to all of you,” says Prof Venter.

According to him, this has not only helped to make infant cardiac screening in the rural areas a reality, but also to make it a world-class service.   

The importance of the partnership for rural areas  

Prof Brown says in his experience, this initiative is greatly appreciated, as he and Dr Buys do the clinics and heart sonars personally. “The families find this fantastic, since they can have direct interaction with their cardiologist, which allows for better communication and adds a personal touch. When they come to Bloemfontein for further assessment – their faces light up when seeing a familiar face.”  

“It also helps with treatment and management at their local institution. I also find that the doctors in the hospitals appreciate it tremendously – they find it easier to phone and ask for advice. It brings the ‘fancy tertiary physicians’ to a human level with whom they can interact. It also alleviates a lot of stress for the physicians, and they can show/ask advice re difficult cases,” says Prof Brown.  

By doing outreach, Prof Brown concludes, they have learned so much about the communities and the importance of being accessible, as patients appreciate having direct interaction with the professor. The doctors and staff have also been enthusiastic and supported them tremendously at all the hospitals. The students from Cuba have joined Prof Brown and his team when visiting their hospitals, and they can spend some dedicated clinical teaching time together.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
