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.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
