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.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
