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.”

The University of the Free State (UFS) awarded an honorary doctorate to Archbishop Emeritus Desmond Tutu on Thursday, 27 January 2011. The graduation ceremony, which was attended by guests from across the country marks a milestone in the history of the university.

Amongst the guests were the ambassador of the USA to South Africa, Mr Donald Gips; the British High Commissioner to South Africa, Dr Nicola Brewer; members of the local government; Ms Barbara Hogan, former Minister of Public Works and the daughters of Bram Fischer, Ruth Fischer-Rice and Ilse Fischer-Wilson. Friends of Dr Tutu, Dr Ahmed Kathrada, Ms Barbara Hogan and Dr Allan and Ms Elna Boesak also attended the occasion.
 
The UFS also received a message of congratulations from the Deputy President of South Africa, Mr Kgalema Motlanthe. “The choice to honour this exemplar of virtue to which most of the world still look for direction as it buckles under social, political and economic difficulties is laudable in all respects,” he said.
Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said: “We honour a great son of South Africa who made a tremendous contribution to peace, reconciliation and justice in South Africa and in the world.
 
“There were times when few of us thought apartheid would end in our lifetime, yet you stood as a rock reassuring us, not about a black future, but about our common future. For this reason, Arch, we would not miss this opportunity to honour you for any reason whatsoever.
 
“You, Sir, are a Jew among Muslims, a Christian among Hindus, a Catholic among Anglicans, a bridge-builder among all of us. That is why we love you; because you look deeper and see further than all of us.”
 
According to Prof. Francois Tolmie, Dean of the UFS’s Faculty of Theology, the university honours Dr Tutu for his contribution as theologian – through his teaching and the books he wrote – as well as for the role he played in bringing about reconciliation in South Africa as well as in the rest of the world. The university also honours Dr Tutu as a moral and spiritual leader who never sacrificed his integrity as a Christian.
 
Apart from being a church leader and a leading world figure, Dr Tutu is the author of several books and also held a number of teaching posts at various tertiary institutions.
 
In 1984, he received the Nobel Peace Prize for his role as a unifying leader figure in the campaign to abolish apartheid in South Africa. A further highlight in his career was his election as Archbishop of Cape Town in 1986. He was the first black African to serve in this position, which placed him at the head of the Anglican Church in South Africa.  
 
Many South Africans also remember the role he played when President Nelson Mandela appointed him in December 1995 to chair the Truth and Reconciliation Commission, which was established to investigate human rights violations during the apartheid era. The Archbishop guided the nation in the process of choosing forgiveness over revenge and in so doing set a historic international precedent.   
 
In 1996, he retired as Archbishop of Cape Town but continues to speak out in favour of human rights, equality and social justice in South Africa and throughout the world.
 
In August 2009, President Barack Obama presented him with the Medal of Freedom, the United States of America’s highest civilian honour. Dr Desmond Tutu is recognised around the world as a moral leader committed to the human rights of all people.
 
Today he is chairman of The Elders, a group of world leaders who, in view of their integrity and leadership, are equipped to deal with some of the world’s most pressing problems.
 
Prof. Tolmie says: “It is often asked how Dr Tutu could have achieved all this in the span of one lifetime. Some people would refer to his warm personality or his humanness, his deep sense of humility or his wonderful sense of humour. Probing a little deeper, however, one is struck by Dr Tutu’s deep relationship with God. He is known as a man of faith, a man of prayer. He lives his life coram Deo, in the presence of God.”
 
Dr Tutu also lead the introduction ceremony of the UFS’s International Institute for Studies in Race, Reconciliation and Social Justice.
