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.”

Food insecurity should not stand in the way of education

2015-06-11

Every year, hundreds of students drop out of university due to financial difficulties – only to return to dire financial circumstances. It is only a few who manage to secure a bursary to fund their studies. These bursaries often pay only for academic and residential expenses, leaving students without additional funding for food.

The University of the Free State realized that up to 60% of its students were food insecure. Many of these students admitted to having to work after class to buy food or having to beg from friends. In 2011, the UFS launched the No Student Hungry Bursary Programme (NSH), which provides modest food bursaries to food insecure students. Currently, 130 students receive food bursaries from the programme to ensure they have one less thing to worry about while they are studying.

This year, at our Autumn Graduation Ceremony, six beneficiaries of the NSH Bursary Programme, received their degrees – an achievement all them feel they could not have reached was it not for the support by NSH.

For Tshililo Nethengwe, accounting student from Venda, her first year at university in 2012 was a daily battle. Although her parents managed to pay her study and accommodation fees, the meager monthly food allowance her parents could afford was not enough to last her the month.

“Every morning I used to tell myself not to think about food because I am here to study. Somehow, I still managed to get something to eat – even if it was just a few slices of bread a day. I was very determined to succeed in my studies, and NSH took away the burden of needing to ‘hustle’ and beg for food.”

Tshililo was one of six NSH recipients who received their degrees and is now doing her honours in B.Com Accounting.

“The NSH Bursary Programme invests in potential, and supports academic achievers who come from challenging backgrounds,” explains Vicky Simpson, co-ordinator of NSH.

“We promote the success of undergraduate students, enabling them to focus on their studies and not on where their next meal will come from. Successful graduates will have a positive and direct impact on our economy, different communities, and many households.”

The NSH food bursary is awarded to students on the basis of financial need, academic excellence, and the commitment to serve the community. We have helped more than 500 students since 2011, when Prof Jonathan Jansen, Vice-Chancellor and Rector, started NSH.

“These students share amazing stories that inspire us. Many had to endure hardship, but they managed to persevere, worked hard, and made it to university. The ability to buy a meal makes an enormous difference.”
