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.”

Student leaders' hard work rewarded
2013-05-01

Four student leaders on our Bloemfontein and Qwaqwa Campuses each received a scholarship of R15 000. Handré Hay, Estine Cronje, Tsepang Lenka and Jean Vermaas were rewarded for the positive impact they had on the student community in the past three years or more. Student Affairs' scholarship programme acknowledges the contribution of student leaders in the upliftment of the student community.

Read what the four have to say about leadership:

Handré Hay:

Handré Hay, a third-year BSc Physiotherapy student who holds several leadership positions on our Bloemfontein Campus, served for two consecutive years on the committee of Armentum residence. He was also a member of the executive council in the Students' Representative Council (SRC) and served in two SRC portfolios. "Leadership is about being able to serve. When people see that you are willing to put other people's interests above your own and that you are willing to serve unselfishly, despite a position of authority, you will get far," said Handré.

Estine Cronje:

Estine Cronje is the current prime of Marjolein residence. This was the second time the fifth-year Psychology student were re-elected to this position."Leadership is very important to me. One needs leaders in everything you do. I believe a leader should never think herself better than the rest and should work as hard as her team. She should command respect, be disciplined, an example to others, accessible and open to the opinions of other people.

Tsepang Lenka:

Tsepang Lenka is the SRC President of our Qwaqwa Campus. Tsepang, who was twice elected as prime of his residence, has already obtained his BA degree in Public and Business Management. He is currently working on his Postgraduate Certificate in Education (PGCE). "To me leadership means to serve. As a leader you don't lie to people when things are taking the wrong direction, you stand firm and tell the truth; in that way, people don't lose trust in you. The scholarship inspires me to work even harder," Tsepang said.

Jean Vermaas:

Jean Vermaas is a former SRC member who is currently studying for his LLB degree. Some of Jean's achievements include leadership positions of the Juridical Society and the Broad Students' Transformation Forum. In 2012 he was a founder member of the Student Elders' Council."Leadership is of extreme importance to me. It formed me into the person I am now. Leadership isn't always easy, but in the challenges you face you grow as a leader and as an individual."
