Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health being presented to the acting Chancellor by his supervisor Prof Stephen Brown.

A lecturer from the University of the Free State (UFS) says the need to improve the care of seriously ill children is a vital part of reducing preventable deaths and diseases, and this led him to investigate the use of artificial neural networks to develop models for the prediction of patient outcomes in children with severe illness. The study was done for his PhD thesis. 

This forms the basis for the PhD thesis of Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health, called, The Development and Validation of Predictive Models for Paediatric Critical Illness in Children in Central South Africa using Artificial Neural Networks. His thesis reports the development and testing of several machine learning models designed to help healthcare workers identify seriously ill children early in a range of resource-limited settings. Combining a systematic literature search and Delphi technique with clinical data from 1 032 participants, this research led to significant progress towards implementable models for community health workers in clinical practice.

Care for critically ill children is a mission and calling 

Dr Pienaar graduated with a PhD specialising in Paediatrics on Monday (12 December) during the Faculty of Health Sciences’ December graduation ceremony. It took him three years to complete this degree. His supervisor was 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 UFS. Prof Nicolaas Luwes and Dr EC George were his co-supervisors. 

“I have been working in paediatric critical care since 2019 and see the care of critically ill children as my mission and calling in life. At the outset of the project, I was interested in approaches to complex phenomena and wanted to investigate new methods for tackling these in healthcare. 

“I have been interested in technology since childhood and in collaborating with other disciplines since I joined the university in 2019. Machine learning seemed like a great fit that could incorporate these interests and yield meaningful clinical results,” explains Dr Pienaar the reason why he chose this topic for his thesis.

He hopes that, in time, this work will lead to the implementation of integrated machine learning models to improve care and clinical outcomes for children in South Africa. From a scholarship perspective, he continues, his hope is that this work draws interest to this field in clinical research and encourages a move towards incorporating these new methods, as well as skills in areas such as coding and design in the armamentarium of a new generation of clinicians.

Medicine chooses you

According to Dr Pienaar, he always had broad interests, of which medicine is one. “I am very grateful to have found my way in medicine and am humbled and privileged to be allowed to walk with children and their families on a difficult and important journey. I believe this profession will choose you and put you where you are needed if you give it time and are prepared to listen.”

He describes graduating as a complicated ending to this period of his life and the beginning of a next chapter. He was humbled by the graduation ceremony. 

“It was wonderful to graduate with undergraduates and postgraduates in my profession – I felt great pride and solidarity joining these new colleagues and specialists in taking the oath. I am certainly relieved, proud, excited, and happy. I am also very grateful to the university, my promotors, colleagues, friends, and family for supporting me through this process. I must confess, it is also slightly bittersweet, I loved working on this and do miss it, but look forward to the next exciting project. 

“I would like to thank my Head of Department, Dr (Nomakhuwa) Tabane, my supervisors, my family and friends once again. I would also like to acknowledge and thank the National Research Foundation (NRF) as well as the University of the Free State for their assistance with funding this research.”

2010 World Cup: An opportunity for nation-building

“The 2010 FIFA World Cup creates a window of opportunity for nation-building in South Africa that could even surpass the opportunity created by the 1995 Rugby World Cup.”

This was according to Prof. Pieter Labuschagne from the University of South Africa, who was one of the three speakers during the lecture series on soccer that were recently presented by the Faculty of the Humanities at the University of the Free State (UFS), in conjunction with the German Academic Exchange Service (DAAD), under the theme: Soccer and Nation Building.

Prof. Labuschagne delivered a paper on the topic, The 2010 Soccer World Cup in South Africa: Nation Building or White Apathy?, highlighting the critical issue of how sport in South Africa was still largely supported along racial lines.

“We are still enforcing the separateness of rugby as a sport for whites and soccer as a sport for blacks,” he said.

He said a high degree of animosity against soccer existed among whites because they felt rugby and cricket were being singled out by parliament as far as transformation was concerned. He said that could be the reason why a large number of South African whites still supported soccer teams from foreign countries instead of local Premier Soccer League teams.

“Bridging social context between different racial groups is still a major problem, even though patriotism is comparatively high in South Africa,” added Prof. Norbert Kersting from the University of Stellenbosch, who also presented a paper on World Cup 2010 and nation building from Germany to South Africa, drawing critical comparisons on issues of national pride and identity between the 2006 World Cup in Germany and the 2010 World Cup.

“Strong leadership is needed to utilize the opportunity provided by the 2010 World Cup to build national unity as former President Nelson Mandela did with the Rugby World Cup in 1995,” said Prof. Labuschagne.

Although acknowledging the power of sport as a unifying force, Prof. Scarlett Cornelissen, also from the University of Stellenbosch, said that, since 1995, the captivating power of sport had been used to achieve political aims and that the 2010 World Cup was no different.

Amongst the reasons she advanced for her argument were that the 2010 World Cup was meant to show the world that South Africa was a capable country; that the World Cup was meant to solidify South Africa’s “African Agenda” – the African Renaissance - and also to extend the idea of the Rainbow Nation; consolidate democracy; contribute to socio-economic development and legitimize the state.

“We should not place too much emphasis on the 2010 World Cup as a nation-building instrument,” she concluded.

She presented a paper on the topic Transforming the Nation? The political legacies of the 2010 FIFA World Cup.

The aim of the lecture series was to inspire public debate on the social and cultural dimensions of soccer.
