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.”

Alcinda Honwana: Youth Protests Main Mechanism against Regime

Prof Alcinda Honwana

"Enough is Enough!": Youth Protests and Political Change in Africa (speech)

The Centre for Africa Studies at the UFS hosted an interdisciplinary project on the Bloemfontein Campus from 20-22 May 2015.

The project, entitled Contemporary Modes of Othering: Its Perpetuation and Resistance, looked at different perspectives, representations, and art forms of otherness, how it is perceived, and how it is resisted.

The annual Africa Day Memorial Lecture was held on Thursday evening 21 May 2015 at the CR Swart Auditorium. Guest speaker Prof Alcinda Honwana addressed the subject of ‘Youth Protests and Political Change in Africa’.

“Youth now seem able to display what they don’t want, rather than what they do want,” Honwana said in her opening remarks. “Thus, we see the young driven to the streets to protest against regimes.”

Honwana shed some light on recent examples of youth protests in Africa that have enjoyed global attention. Looking at the protests in Tunisia (2010), Egypt (2011), Senegal (2012), and Burkina Faso (2014), it is clear that these events in northern and western Africa have inspired others globally. Yet, Honwana stated that, despite these protests, no social economic change has been seen, and has left dissatisfaction with new governments as well.

“Once regimes fall… young activists find themselves more divided, it seems…

“Which leaves the question: Will street protests remain young people’s main mechanism to avert those in power?”

Background on Prof Alcinda Honwana:

Alcinda Honwana is currently Visiting Professor of Anthropology and International Development at the Open University (UK). She was chair in International Development at the Open University, and taught Anthropology at the University Eduardo Mondlane in Maputo, the University of Cape Town in South Africa, and the New School for Social Research in New York. She was programme director at the Social Science Research Council in New York, and worked for the United Nations Office for Children and Armed Conflict. Honwana has written extensively on the links between political conflict and culture, and on the impact of violent conflict on children and youth, conducting research in Mozambique, the Democratic Republic of the Congo, Angola, Colombia, and Sri Lanka. Her latest work has been on youth and social change in Africa, focusing on Mozambique, Senegal, South Africa, and Tunisia.

Honwana’s latest books include:

• Youth and Revolution in Tunisia (2013);
• Time of Youth: Work, Social Change, and Politics in Africa (2012);
• Child Soldiers in Africa (2006);
• Makers and Breakers: Children and Youth in Postcolonial Africa (2005, co-edited).

Honwana was awarded the prestigious Prince Claus Chair for Development and Equity in the Netherlands in 2007.
