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.”

Kovsie Tennis team defends proud USSA record in Cape Town

Duke Munro already has six gold medals from the USSA Tennis Tournament in his cupboard, and the Kovsie Tennis team would wish to bid him farewell in a fitting manner during what will probably be his last tournament in Cape Town.

This year's tournament, taking place from 30 November to 4 December 2015, will probably be Munro's last, since he is completing his Master's degree in Quantity Surveying at the University of the Free State (UFS).

He has competed in the USSA Tournament since 2009, and would like to help his team defend its proud record.

UFS aim for ninth consecutive title

Kovsies have won gold at the USSA Tournament for the last eight years. They are the only team who have been able to win the tournament since the combined format was adopted in 2010. In 2007 and 2008, their Women's team won the tournament, and in 2009, their Men's team.

Kovsies will play in group matches against the Universities of Venda and Wits on 30 November 2015, against the University of Cape Town's (UCT's) second team on 1 December 2015, and against UCT's first team on 2 December 2015. The cross and knockout matches will be played on 3 and 4 December 2015.

Other sporting codes

The Sevens Rugby team from the UFS will compete in the USSA Tournament in George on 30 November and 1 December 2015.

For the past two years, the team has won bronze, and will be playing three league matches on 30 November 2015 against the North-West University's Vaal Campus, Nelson Mandela Metropolitan University's Port Elizabeth Campus, and the Vaal University of Technology.

Kovsies are the current Varsity Sevens Champions after winning the title in Cape Town in April 2015.

Ten Kovsie swimmers took part in the USSA Tournament in Johannesburg from 28 November to 30 November 2015. Last year, Kovsies came third, but unfortunately some of their leading swimmers were unable to take part this year.

The Kovsie Table tennis team will participate in the USSA Tournament in Kimberley from 30 November to 4 December 2015.

Most of the USSA Tournaments in the other sporting codes were either postponed or cancelled because of the recent nationwide student protests. As a result of the protests, exams were written later, and tournaments would have taken place during the holidays.

Only the tennis, table tennis, Sevens rugby, swimming, and cricket B Division in East London will continue.

The USSA Soccer Tournament, to take place at the UFS and the Central University of Technology in Bloemfontein, was postponed until March 2016.
