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.”

The Faculty of Theology and Religion recently hosted the annual Tutu-Jonker Prestige Lecture Series at the Bloemfontein Campus of the University of the Free State (UFS). The purpose of the lecture series is to address modern-day and pressing social challenges from a theological and religious perspective.

With the theme Religions and reconciliation of conflicting identities, guest speaker and Desmond Tutu Chair on reconciliation at the Faculty of Theology: Vrije Universiteit Amsterdam, Prof Eddy van der Borght, spoke about the reformation in the context of shifting European identity formations.

Reconciliation versus social identity

“My focus is on what the Christian concept of reconciliation means for reconciliation in society,” said Prof Van der Borght. He deliberated the global problem of conflict generated by diverse social identities. He also emphasised that religion has huge resources to contribute towards overcoming conflicting identities.

“The theory is that religions know about reconciliation, while in practice it is much more complicated, because often religions are part of the problem of conflict,” he says. He said religions are often the problem in social cultural identities, especially regarding conflict involving different nations, racial, and ethnic groups.

Honouring prominent theologians Tutu and Jonker

The name Tutu-Jonker originates from the two theologians, Emeritus Archbishop Desmond Tutu and the late Prof Willie Jonker, who are both regarded as prominent theologians known for their emphasis on reconciliation in South Africa. The significance of combining the two names is said to bring together two different theological traditions (Anglican and Reformed), cultural groups, and races.

Prof Fanie Snyman, Dean of the Faculty of Theology and Religion, said, “This will also serve the purpose of a welcoming culture at the faculty, embracing diversity and embodying reconciliation.” Both of these theologians received honorary doctorates in Theology from the UFS.
