Heinrich Janse van Rensburg’s is a 5th year medical student from the University of the Free State whose photo was highly commended at the Imperial College London’s Global Creative Competition: Medical Student Responses to COVID-19.

A late-night photo taken through a window at the Pelonomi hospital by a final-year medical student from the University of the Free State (UFS) was highly commended at the first Global Creative Competition: Medical Student Responses to COVID-19.

The competition, held by the Imperial College London, received more than 600 entries from more than 52 countries. The competition was held to bring together the global community of medical students to submit their creative responses to COVID-19 and to provide a platform for them to reflect on their personal and professional experiences during this challenging time.

Medical students from around the world could enter in two categories; visual and literary, and the winners were announced during a Global Awards Ceremony on 14 October.

Meaning behind the photo

Heinrich Janse van Rensburg’s late -night photo highlights the economic inequality that persists in South Africa. The photo was taken from the Pelonomi Hospital which is located in Heidedal, Bloemfontein, and shows the old, forsaken Dutch Reformed church in the foreground, shacks in the background with smoke billowing from the dwellings, where up to six people live in one room trying to stay warm during winter. They are built so close to each other that there can be no talk of effective social distancing.

According to Janse van Rensburg the theme of inequality in the South African milieu is further shown in the striking contrast between light and dark in the picture. “And now, with the COVID-19 pandemic placing a massive burden on an already struggling healthcare system the inequality is even more visible,” says Janse van Rensburg.

A little shocked 

He was a little shocked when he heard his photograph was highly commended. Janse van Rensburg says: “Imperial College London is a big institution and being an international competition I did not really expect a lot. There were participants from over 52 countries, and having seen some of the works that were submitted it feels special to be one of the students being noticed.”

Janse van Rensburg, who has never considered doing art, heard about the competition through the Faculty of Health Sciences platforms during lockdown level 5. He saw it as an opportunity to reflect, which has become even more imperative in times like these.

He says he does not go searching for art, but “notices” it from being conscious – something he thinks is important in medicine and life.

Value of creativity in promoting mental well-being

Dr Lynette van der Merwe, undergraduate medical programme director, School of Clinical Medicine, congratulated Janse van Rensburg, saying this commendation in an international competition underscores his talent and the value of creativity in promoting mental well-being.

“Heinrich’s artwork and showcase precisely what we aspire to develop in our exceptional UFS doctors-in-training: a professional with self-awareness, empathy and humanity.

“We initiated a Mental Health Awareness initiative and art competition in the School of Clinical Medicine in 2018 to promote creative expression as a means of supporting students’ mental health. Heinrich has won awards with his creative contributions every year, exhibiting his imaginative ability.”

Surgery and photography

Janse van Rensburg says he has always loved beautiful things and the meaning people attach to art is a good way to communicate that. He has applied for an internship at the Mitchells Plain hospital for when he completes his studies at the end of this year and is thinking of specialising in reconstructive or pediatrics surgery. Besides that, he would like to tap into his creative side and continue with the photography.

Fight against Ebola virus requires more research
2014-10-22

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.
