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.”

Today (Thursday, 27 January 2011), almost three years after the Reitz affair, the University of the Free State (UFS) is launching its International Institute for Studies in Race, Reconciliation and Social Justice. This international institute will be inaugurated by Archbishop Emeritus Desmond Tutu, Nobel Peace Prize Laureate and Chairperson of the former Truth and Reconciliation Commission, who received an honorary doctorate in Theology from the university earlier today.

According to Mr John Samuel, Interim Director of the institute and former Chief Executive Officer of the Nelson Mandela Foundation, the institute seeks to establish itself as a premier international site for research on race, reconciliation and social justice.

“It is encouraging to see the UFS bringing to the fore such an initiative, which combines a study in race, reconciliation and social justice, all of which are indispensible elements in the process of rebuilding our nation,” said the Deputy President of South Africa, Mr Kgalema Motlanthe, in his message of congratulations to the university.

“I am confident that on the strength of its stature, coupled with its eminent experience as an academic institution, the UFS will further assist our country advance towards a united, non-racial, non-sexism, just and prosperous future.

“I wish the institute well in its arduous but noble task of contributing to the building of a better human society,” he said.

Prof. Jonathan Jansen, Vice-Chancellor and Rector, stated during his official inauguration in 2009 that the university would be an example of a place where reconciliation, forgiveness and social justice would not only be studied, but where it would also be applied in practice. “Students and scholars from across the world will come to the UFS to study the theory and practice about the building of societies across the boundaries of race, as well as religion, gender, disabilities and national origin,” Prof. Jansen said.

The institute is a critical space where engaged scholarship, public discussion, community engagement and teaching are innovatively integrated towards exploring and finding solutions to the complex and challenging work of social transformation in South Africa.

The institute furthermore works towards the realisation of its mission through a multiplicity of approaches and methods, informed by the notion that deep and complex social challenges require courageous and challenging scholarship, supported by innovative organisational forms and institutional arrangements.

Working from the inside to the outside, the institute will firstly serve the needs of the university, its staff and students. Through its research, the institute will endeavour to understand the challenges facing the UFS better, as well as how to address these challenges. For this reason, the concept of the UFS as a “live laboratory” and the use of evidence-based practice remain important for the university.

The institute will also reach out and empower its stakeholder communities through research and ongoing involvement on issues of race, reconciliation and social justice. Furthermore the institution expects to contribute to the creation of national and international networks and dialogue platforms pertaining to race, reconciliation and social justice.

For the first five years, the themes of 1) Values, Faith and Social Justice; 2) Development and Social Cohesion; 3) Teaching and Learning for Social Justice; and 4) Provincial, National, Global Perspectives and Leadership will direct the institute’s work.

The UFS will make a substantial contribution to the pursuit of reconciliation, greater social cohesion and equity in South Africa. The university is thus prepared to continue to engage the difficult, practical and trying work of building a strong, quality institution as it promotes racial healing and addresses the structural imbalances of the past. It is at this nexus that the institute commits to enabling change at the university as well contributing to transformation in South Africa.
