Dr Tabane — Dr Lizzy Tabane, Head of Paediatrics and Child Health in the Faculty of Health Sciences at the University of the Free State, gives a message of support at the 2023 SAPA Conference.

The Department of Paediatrics and Child Health at the University of the Free State (UFS) recently hosted the 2023 South African Paediatric Association conference (SAPA) in Sandton, Johannesburg, with more than 200 doctors, specialists and registrars in attendance.

The conference aimed to provide high-quality, evidence-based updates on children’s health issues and research in health care. The three-day conference focused on presentations from various paediatricians in South Africa’s health sectors.

Conference presentations

The conference explored new ways of treating different types of childhood diseases, and covered a range of topics such as learning disabilities and inclusive education, sports for children with asthma, septic shock, dyslipidaemia in children, congenital heart disease among others.

Collaborations with healthcare professionals

Head of Paediatrics and Child Health at the UFS, Dr Lizzy Tabane and her colleagues, Dr Mampoi Jonas and Prof Ute Hallbauer, were pleased with the success and outcome of the conference.

According to Dr Tabane, the professionals gather once a year to learn, exchange ideas and work together to ensure the best possible care for children in hospitals.

“The SAPA conference presents health professionals across South Africa with the latest information on paediatric health. It also ensures that children in our country continue to receive quality care through an integrated approach by allowing health professionals to connect, network, and share their knowledge and expertise,” said Dr Jonas.

“The country and the community at large are in good hands,” said Dr Tabane. “Let us not fall behind but catch up with the latest innovations, for instance, Artificial Intelligence and Machine Learning in Medicine. Our partnership with all paediatrics and other health professionals will bring unity and good child health care in our country."

“What is important is the tremendous support from all the specialists, doctors and practice nurses from different health-care departments who have consistently turned out in large numbers. The success of the conference extends beyond GPs, such as drawing in specialists, clinicians, nurses, and professionals dedicated to children’s well-being within hospitals and the community,” emphasised Dr Tabane.

Significance of the conference

Prof Hallbauer emphasised the significance of fostering collaboration to enhance integrated care, spanning both the hospital system and primary care. “This annual conference confirms our commitment to working together as doctors for the well-being of our patients. The motto we have chosen is Carpe Diem ‘Seize the Day’. For the conference this means taking hold of the programme and making the most of each conference day.

“When you meet your colleagues, build and strengthen the collegial networks, so that we can realise Letshwele le beta phoho – a SeSotho idiom meaning ‘The crowd beats the bull’,” added Prof Hallbauer.

This conference “will strengthen our relationship” with other doctors and make the health system a better place, concluded Prof Hallbauer.

Nanotechnology breakthrough at UFS

2010-08-19

Ph.D students, Chantel Swart and Ntsoaki Leeuw

Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil.

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
