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.”

Internationally acclaimed academic applauded on Africa Day
2011-06-02

 
 Prof. Ali Mazrui, an internationally acclaimed and renowned academic.

One of the world’s top academics was given a warm welcome in the rather cold Free State recently.

Prof. Ali Mazrui, an internationally acclaimed and renowned academic, visited us as part of our Africa Day celebrations as arranged by the Centre for Africa Studies. He delivered a keynote address, entitled ‘Pro-democracy uprisings in an African experience: from Sharpeville to Benghazi.’

A festive atmosphere and the sound of drums welcomed this intellectual giant as well as other delegates upon their arrival at the CR Swart Auditorium on our Bloemfontein Campus. Some of the delegates who attended the Africa Day Celebrations, included: Mr Tom Amolo, High Commissioner from the Republic of Kenya; Mr Dan Kgothule, MEC of Arts and Culture in the province; Prof. Jeff and Dr Carla Ramsdell, visitors from America; Dr Allan Boesak and Prof. Nicky Morgan, Vice-Rector: Operations.

Prof. Frederick Fourie, former Vice-Chancellor and Rector of our university, also attended the celebrations, as did some scholars from neighboring schools.

Welcoming Prof. Mazrui, Prof. Jonathan Jansen, Vice-Chancellor and Rector of our university, quipped that he was relieved the world had not ended the previous weekend as was predicted, because he was looking forward to listening to such a renowned intellectual.

Prof. Lucius Botes, Dean of Humanities, followed Prof. Jansen at the podium. He said the ability to go from following a bridging course to being one of the top 100 intellectuals in the world, indeed distinguishes Prof. Mazrui as an exceptional academic. This intellectual is, among others, an Albert Luthuli Professor at the University of Jos, Nigeria and Andrew D. Professor Emeritus and Senior Scholar in Africana Studies at Cornell University.

In his introduction, Prof. Mazrui said he feels honored and flattered by this opportunity. He proceeded by referring to the history of Africa Day and added that he would rather prefer an Africa Week to an Africa Day to ensure that everybody has the opportunity to celebrate the continent.

He sang the praises of South Africa, as almost every other African country which attained liberation from European colonial rule in the 20th century, has been unable to maintain its democratic order beyond its first decade of independence.

“The Republic of South Africa, on the other hand, liberated Nelson Mandela in 1990, held its first democratic election in 1994, and already has its third president. Nearly two decades after Apartheid, South Africa has not outlawed opposition parties, or experienced a military coup, or permitted the Head of State to govern the country as a dictator.”

In his speech he compared the uprisings in Sharpeville during 1960 and Soweto during 1976 with the more recent pro-democracy uprisings in North Africa, based on the role that weapons and the lack thereof, as well as the youth and women played in the respective cases.

He concluded by saying the uprisings in Tunisia and Egypt have already resulted in ousting dictators who had been entrenched in power for decades, adding that in Libya a third dictator’s future is on the line. “Never in the history of the Arabs have there been so many popular uprisings which seem to be inspired neither by Islam nor by anti-imperialism, but in the quest for liberal reforms. Half a century earlier in Sharpeville and Soweto, South Africans experienced their own political awakening.”

Prof. Kwandiwe Kondlo, Director of the Centre for Africa Studies, closed the event with a word of thanks to the American academic and his wife, guests and attendees. He said discussions prior to the event revealed that more research has to be done regarding gender issues on the continent.

Prof. Mazrui also participated in conversations at the institute and a media briefing which was hosted earlier the day.
