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.”

The UFS #FaceOfFacebook

2014-11-14

At the UFS, we are committed to our Human Project, which sets the standard for good behaviour and care. It reaches internally to our students and externally to our prospective students and our communities.

And so, the Kovsies #FaceOfFacebook was born from the need to communicate with students and thus become a virtual friend. Yearly auditions are held to choose the new face representing the UFS on Facebook. The successful candidate holds the title #FaceOfFacebook for the next 12 months, attending events and filming short video clips to post on our Facebook page.

We had a quick chat with our current #FaceOfFacebook, Katleho 'Blue' Letube …

Who is Blue?

"Media mistress, fashion phenom, diva divine darling, superwoman and lover of life.
I was born in a small town called Bothaville, where my mom and her side of the family are living . I started pre-school there, moved and completed my schooling career at St. Andrew's High School (a very proud S aint) in Welkom. That is where my dad and his side of the family are living . Also, I am a proud resident of House NJ vd Merwe and I am studying Governance and Political Transformation."

How do you balance everything you do?

"It's relatively easy for me to strike a balance between my academics, social life and leadership duties, because Jesus is at the centre of all that I do. He is my guide and my strength. However, I also take it upon myself to prioritise. Although I am a '' liker of things'' , I ensure that my academics are the priority and everything else falls into place perfectly."

Are you dating someone?

"Hahaha, wouldn't you just love to know? Well, yes I am off-market. I'm completely taken and I'm happy."

What drives you?

"I always feel the urge to expand myself by working harder, smarter, stronger, and more efficiently. If there's an extra mile to go, the strength inside me draws out the willingness and ability to go that extra mile."

What is it like being the #FaceOfFacebook?

"I have been privileged to be entrusted with this duty and I carry it out with pride and passion. Being the #FaceOfFacebook means you get to meet a new face on campus almost every day, because people recognis e you and want to know you better. This opportunity has opened many doors for me and has equipped me with skills that have allowed me to grow as an individual. Therefore I will forever be grateful."

Where are you going to be in five years from now?

"Five years from now I would like to see myself as a better person both personally and professionally, in a respectable and reputed position earned through my hard work and skills. However, do not be surprised if you see me as a presenter on Vuzu.TV."

Advice to prospective students?

"Do not be that pupil who enrolled at this awesome institute and never takes advantage of its kindness. The University of The Free State is an institution that offers an excessive amount of opportunities to students. Step up and get out of your comfort zone. See an opportunity, seek the opportunity and cease it. You are at a university that provides you with a platform for you to grow."

What's your favourite colour?

My favourite colours are Black, White and Blue – hahaha!!
