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.”

Meet the person behind the title – your new FaceOfFacebook

2015-04-29

Kovsies #FaceOfFacebook was born three years ago out of a need to engage with students, and become a virtual friend. Auditions are held every year to choose the new ‘face’ representing the UFS on Facebook. The successful candidate holds the title as #FaceOfFacebook for the next 12 months, attending events, and filming short video clips to post on our Facebook page.

The votes have been counted, and we have a winner. After much excitement and a close contest, Nompumelelo Maseko (whose name, fittingly, means ‘success’) emerged victorious from the top six contestants selected by our panel of judges. We sat down with the soft-spoken Mpumi – as her friends call her – to get a sense of the person who will be our ambassador for the next year.

What is your field of study, and how far along are you?

I am studying for a BSc degree in Genetics, and I’m currently in my second year. I have a particular interest in the forensic sciences, which fascinate me!

Are you originally from Bloemfontein?

No, I am originally from Pretoria.

How is it that you ended up here, studying at the UFS?

Before leaving school, I applied to various universities, but my desires and ambitions brought me here.

How do you find your residence?

Akasia ladies are big on sisterhood, very supportive. Res life is very enjoyable.

What do you hope to accomplish during your term as the #FaceOfFacebook?

I would like to help people become aware of what is taking place on campus. There are many opportunities to be more engaged with what is happening at the varsity. For instance, there are still many people who don’t really know what the #FaceOfFacebook is, and I would like to help inform them about it.

What is your motivation in your studies, in taking part in this contest, and in life?

I am intrigued by the function of life forms, the differences that exist at a cellular level.
For this competition, I fed off my love of people, even though I am shy. I also enjoy presenting.

I have my parents to thank as my motivation, as well as meeting and engaging with people. I find that I achieve a broader perspective when I don’t restrict myself to my own opinions, but strive to be open to differing views.

Nompumelelo will be appearing in one of her first Facebook videos shortly, so be sure to keep an eye on our Facebook page.
