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

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.”

Moshoeshoe's legacy lives on in university's project

MATEFU MOKOENA

DRUMS were beaten and the sounds of traditional songs reverberated through corridors of the University of the Free State (UFS) as Basotho students gathered at the campus over the weekend to launch a project honouring their late great king, Moshoeshoe.

The launch was organised by the Lesotho Students Association and UFS management and was blessed by King Letsie III of Lesotho.

According to UFS rector and vicechancellor, Professor Frederick Fourie, the aim of the project is to make the legacy of Moshoeshoe a living part of the university.

He said the Moshoeshoe project will include a television documentary on his life as well as an anthology of creative writings, including prose and poetry, about him.

A television documentary is already being filmed and will be screened during an international conference at UFS in October.

Fourie said the university, as part of the project, is looking at the possibility of starting an annual Moshoeshoe memorial lecture that will focus on African leadership, nationbuilding and reconciliation.

He said the university would introduce a PhD-level research course into the life and legacy of Moshoeshoe.

The university management has also taken a decision to erect a statue of Moshoeshoe on the campus.

Fourie said the project was launched after the UFS delegation, led by him, met Letsie III.

"He wanted us to ensure the legacy of Moshoeshoe is honoured and treated with the respect he deserves."

His legacy "must live on -- not only for the Basotho, but for all South Africans, black and white, and for the entire African continent", he said.

"Living out such a legacy is indeed a fitting contribution to the New Partnership for Africa's Development (Nepad) and to the maturing democracy that is being built here in South Africa," said Fourie.

He emphasised Moshoeshoe was and remains a model of African leadership.

Fourie said Moshoeshoe's diplomacy and commitment to peace put him on a par with former president Nelson Mandela as a statesman.

It is Fourie's dream that, through this project, the UFS will be able to give real meaning to words such as reconciliation, respect for the diversity of languages and cultures and the unity that is needed to build a democratic nation.

The Lesotho Students Association secretary, Sofonea Shale, said for an institution like the UFS to honour Moshoeshoe demonstrates that he was a great leader. "For Basotho students, the project is very significant as it clearly defines who we are and what we stand for.

"We believe the research into the legacy of our great king Moshoeshoe will open doors for more research into the life of Basotho in general.

"Africa as a whole can learn from his leadership style," he said.
