Need to improve the care of seriously ill children leads to PhD

14 December 2022 | Story André Damons | Photo André Damons

Dr Michael Pienaar 1 — 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.”

Faculty of Law establishes unique panel of advisors

Some of the panel members who attended the Collegium Iurisprudentium of the Faculty of Law at the UFS were from the left His Honorable Judge of Appeal Lex Mpati (Vice-President of the Supreme Court of Appeal), His Honorable Judge of Appeal Joos Hefer (former Chief Justice of South Africa), His Honorable Judge of Appeal Frits Brand (Supreme Court of Appeal) and Mrs Alet Ellis (lecturer at the UFS Faculty of Law).

At the back from left were Prof Johan Henning (Dean: Faculty of Law at the UFS), His Honorable Judge Faan Hancke (High Court of the Free State and chairperson of the UFS Council) and Adv Jannie Lubbe Sc.

The Faculty of Law at the University of the Free State (UFS) has established a panel of advisors comprising of all the honorary and extraordinary professors of the faculty.

“The faculty has been known for its excellent practice-orientated training as well as the involvement of law practitioners in the training of LL B-students,” said Prof Johan Henning, Dean of the Faculty of Law at the UFS.

“The faculty was greatly dependent on the services of advocate lecturers, full-time members of the Bar and Side Bar who lectured on a part-time basis at the faculty. For this reason lecturing in the faculty was mainly done after-hours to part-time students,” said Prof Henning.

With the shift in emphasis to full-time lecturing and the appointment of full-time lecturers, especially because of the increasing student numbers, the full-time LL B-programme and the increasing pressure on students for quality research inputs, a greater need for meaningful contributions of judges and senior law practitioners to the faculty was experienced.

“To comply with this urgent need, three honorary professors and nine extraordinary professors were appointed. This group of experts deliver an indispensable contribution to the practice orientation of the faculty by means of formal lectures, public inaugural lectures and guest lectures, direct lectures to graduate and post-graduate students, participation in research projects and the constant evaluation of lecturers, modules and the content of modules and learning material. The international exposure of students and lecturers is also promoted by their contribution,” said Prof Henning.
“A need to have the involvement of this special class of professors structured in a more organised way was identified and a decision was made to establish an advisory panel called Collegium Iurisprudentium. It is a privilege to us that all the honorary and extraordinary professors accepted the invitation,” said Prof Henning.

The panel will provide the faculty with continuous, distinguished, practice- orientated capability and capacity as well as international expertise, not only for direct inputs to students but also to advise lecturers about the curriculum, the compilation of the content of the LL B and M module, learning material and others, as well as to strengthen the research capacity of the faculty.

“The panel will also deliver a decisive contribution to the faculty’s preparation for the constitutional audit of the Higher Education Quality Committee (HEQC) of the Council for Higher Education (CHE) that will take place in October 2006,” said Prof Henning.

The Collegium Iurisprudentium, which has been formally constituted, comprises of:

Appeal Court Judge J J F Hefer,
Appeal Court Judge L Mpati
Appeal Court Judge F D J Brand
Appeal Court Judge I G Farlam
Prof B A K Rider
Judge S P B Hancke
Judge A Kruger
Judge D H van Zyl
Adv S J Naudé
Adv J Lubbe Sc
Prof M M Katz
Prof R J Cook
Mr S van de Merwe
