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.”

Help to rural women to become entrepreneurs

Alexander Forbes and UFS help rural women to become entrepreneurs

Today, the Alexander Forbes Community Trust and the University of the Free State (UFS) joined forces to create an enabling environment for rural women to become players in the private sector.

Three years ago the UFS set up a unique small-scale household egg production project called Women in Agriculture in Thaba ‘Nchu as a pilot project. The project was officially launched today by Mr Donray Malabie, Head of the Alexander Forbes Community Trust.

The aim of the Women in Agriculture Project is to create jobs, provide food security and to help develop rural women into entrepreneurs. A total of 25 women based in Tabane Village in Thaba ‘Nchu are the beneficiaries of the project.

“This is the first project in the Free State the Alexander Forbes Community Trust is involved with. The project would help rural women acquire the skills they need to run their own egg-production business from their homes,” said Mr Malabie.

“The ongoing debate on the shortage of skills ignores the fact that people with little or no education at all also need training. This project is special to the Trust as it provides for the creation of sustainable jobs, food security and the transfer of much needed skills all at once, particularly at this level,” he said.

Every woman in the group started with two small mobile cages that housed 12 hens each. The units are low in cost, and made of commercially available welded mesh and a metal frame. Now, each woman has four cages with 48 hens. The group manages to collectively produce 750 eggs daily.

The eggs are currently sold to local businesses, including spaza shops and the women are using the income generated to look after their families and to further develop their business.

The Department of Animal and Wildlife and Grassland Sciences at the UFS identified the project and did the initial research into the feasibility of setting up such a project.

“A demonstration and training unit has been established at the Lengau Agricultural Development Centre and the women attended a short practical training course. Subsidies are provided for feeding, together with all the material and the lay hens necessary for the start of the business,” said Ms Khoboso Lehloenya, coordinator of the project from the Department of Animal and Wildlife and Grassland Sciences at the UFS.

“The advantage in using lay hens is that they are resistant to diseases and the women will not need electric heating systems for the egg production,” said Ms Lehloenya.

According to Ms Lehloenya, the women are already benefiting from their egg production businesses. “Some of them have used the profit to buy school uniforms and tracksuits for their children and others are now able to make a monthly contribution to their household expenses,” said Ms Lehloenya.
“In South Africa, possibly due to cultural reasons and circumstances, most black people prefer to eat older and tougher chickens, compared to younger soft commercially available broiler chickens. This preference creates a further advantage for the women. At the end of their production cycle, old hens can be sold for a higher price than point-of-lay or young hens. This brings in further money to pay for more hens,” said Ms Lehloenya.

The Alexander Forbes Trust contributed R191 000 towards the project aimed at expanding it to benefit 15 more women.

“We are in the process of recruiting an additional 15 women in Thaba ‘Nchu who will be trained by the Lengau Agricultural Development Centre in order to replicate the model and extend its reach”, said Ms Lehloenya.
