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.”

The University of the Free State (UFS) has launched four exciting projects set out to improve the circumstances of its current and prospective students. These include a project that will honour dedicated and influential educators.

These community service projects in the starting blocks are: the UFS Schools Partnership Project, Extreme Make-over Project, Great Teachers Project and the No Student Hungry Campaign.
 
The Schools Partnership Project aims to support 21 schools across the Free State in helping them to become top achievers in the next three to five years. The schools involved were selected last year, after which the groundwork for the project was finalised. Although it mainly focuses on improving scholars' results in mathematics, accounting, physical sciences and English, it is also custom-designed according to the specific needs of the school, as indicated by the respective governing bodies beforehand. As a bonus, scholars of the schools involved will be given an opportunity to be introduced to student life; something Dr Choice Makhetha, UFS Vice-Rector: External Relations (acting), claimed to be of great importance. “We will invite Grade 10 to 12 learners to winter and summer schools being presented at the university. We will connect learners with students (one student adopts one learner for the day) for them to experience campus life. Grade 12 learners will also receive an invitation to the May 2011 graduation ceremony,” Dr Makhetha said.
 
Adding to the university's involvement at schools on local level, the newly upgraded Bloemfontein-Oos Intermediary School with its 112 UFS-sponsored tables will officially be revealed by the end of April. Although this school's upgrade showcases the power of partnerships, it is of special importance to the university, as it also marks the first school to receive an extreme make-over as part of the 'Extreme Make-over for Schools Project'. This project, in conjunction with the local business community, university staff and students, the community, the Department of Basic Education and SIFE (Students in Free Enterprise), is considered to be a flagship project of the Vice-Chancellor and Rector, Prof. Jonathan Jansen. Part of the project’s agreement includes visits from a group of about 100 students representing campus initiatives such as the UFS’s Kovscom, Rag and SIFE, which will contribute to the improvement of the schools' resources within a period of 10 – 15 weekends. “We invite support from all corners. South Africa has a business community committed to improving the social circumstances of its community and we plead that they also come to the rescue of the Bloemfontein-Oos Intermediary School,” said Dr Makhetha.
 
By spreading a 'can do' attitude, the UFS aims to honour noble and remarkable teachers across the country by means of its 'Great teacher's project'. Through the project, fellow citizens are encouraged to submit their stories on their former or current teachers’ dedication and their positive impact which are often overlooked. The panel of seasoned education scholars and practitioners will select the top 500 stories based on the stories' clarity, distinctiveness, plausibility and affectability, which will be perpetuated in a book called 'Great Teachers', to be released at the end of this year. Proceeds are destined to serve as bursaries for students who wish to pursue a career in education. According to Prof. Jansen the ideal teacher is: “Somebody who was among, but stood out above, their colleagues, a person who made a lasting impact long after the details of subject matter content of examination preparation were forgotten.”
 
Regardless of this exceptional effort of supporting schools across the province, the UFS remains committed to its students and their social welfare by means of the 'No student hungry' campaign. This project provides financially challenged students the opportunity to purchase food from the Thakaneng Bridge on the Main Campus in Bloemfontein by using their student cards at two selected kiosks serving balanced meals. The project, which is under the guardianship of Ms Grace Jansen and Dr Carin Buys, relies solely on several fund-raising projects across the country. These women are the respective spouses of the Rector and Dean: Student Affairs, Mr Rudi Buys. According to Ms Jansen this initiative was proposed after UFS staff reported that many students were struggling to concentrate on their studies due to hunger pangs. Although the campaign recognizes students with strong academic records, it doesn't overlook those who need a food bursary which might result in them dropping out. Ms Jansen said as the external funds gathered increase, so will the amount of students being supported by the project. “The plan is to continue until the fate of hungry students had come to an end,” she said.
