Prof Stephen Brown
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.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
