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.”

2014 Winter Graduation
2014-06-27

 
It is time for the 2014 Winter Graduation on our Bloemfontein Campus. From 2 – 4 July 2014 Masters and Doctoral degrees will be bestowed on graduates from across all seven faculties as well as the School of Open Learning. These include the conferral of Medicine degrees on the South African Cuban trainees.

Wednesday 2 July 2014 at 14:30: School of Open Learning
The School of Open Learning will confer a total of 609 degrees this year – almost double compared to the 320 of last year.

Thursday 3 July 2014 at 09:30: Faculty of Natural and Agricultural Sciences
Prof Magdalena Blum will receive an Honorary Doctorat, DPhil honoris causa, at this event. Prof Blum is an Extension Systems Officer in Rome. She works for a specialised agency of the United Nations called the Food and Agriculture Organization. This organisation’s mandate is:
• to improve nutrition,
• increase agricultural productivity,
• raise the standard of living in rural populations and
• contribute to global economic growth.

Her position serves to modernise and strengthen rural advisory services, their systems and networks worldwide. She has filled this position for almost nine years.

Prof Blum is driven by a passion for development, humanitarian work and female upliftment, but most of all, to enable people to help themselves.

Blum’s life has taken her from a small German village to Africa, Asia and Europe – and she has made an impact wherever she went.

Thursday 3 July 2014 at 14:30: Faculties of Economic and Management Sciences, Humanities, Education, Health Sciences, Law and Theology
At this ceremony, Faculty of the Humanities will award an Honorary Doctorate, DPhil honoris causa, on Prof Laura Mulvey. She is a feminist film theorist and worked at the British Film Institute for many years. She is currently a professor at Film and Media Studies at Birkbeck, University of London.

Prof Mulvey was prominent as an avant-garde filmmaker in the 1970s and ‘80s. In collaboration with her husband, Peter Wollen, she co-wrote and co-directed:
• Penthesilea: Queen of the Amazons (1974),
• Riddles of the Sphinx (1977, perhaps their most influential film),
• AMY! (1980),
• Crystal Gazing (1982),
• Frida Kahlo and Tina Modotti (1982), and
• The Bad Sister.

In 1991, she returned to filmmaking with Disgraced Monuments, which she co-directed with Mark Lewis.
