Prof Mokgadi Matlakala
Prof Mokgadi Matlakala, Academic Chairperson of the Department of Health Studies at UNISA and Deputy Chairperson of the Forum for University Deans in South Africa (FUNDISA), was the keynote speaker and acknowledged the contribution of nurses and the courage to continue to advocate for improved health and healthcare.

Nurses serve with pride, and they should be protected, valued, and respected.

This was the recurring thought from speakers at the University of the Free State (UFS) School of Nursing’s International Nurses Day celebrations.

“We celebrate this day to highlight the importance of nurses in the healthcare services, and to honour our heroes – us being the heroes as well,” said keynote speaker Prof Mokgadi Matlakala, Academic Chairperson of the Department of Health Studies at UNISA and Deputy Chairperson of the Forum for University Deans in South Africa (FUNDISA). “We acknowledge the contribution of nurses and the courage to continue to advocate for improved health and healthcare – and this amid the challenges confronting us.”  

Prof Matlakala said the theme of the day, “Our Nurses. Our Future”, comes at a very critical time for the nursing profession, given the circumstances following the COVID-19 pandemic, and the ongoing transformation needed in nursing education, particularly in South Africa. 

International Nurses Day is celebrated annually on 12 May, and this year the UFS School of Nursing also hosted a tree-planting to commemorate nurses who lost their lives during the pandemic. Several other activities, including an Amazing Race, outdoor events, and stalls portrayed nursing services in various contexts. 

Prof Matlakala said the day also serves as a way of sharing ideas about changes taking place in nursing, and imagining a nurse of the future, both in practice and academia. “In the African context, it is important for us to reflect and understand who our nurses are, where are they, and where have they been trained.”

World mistakenly took nurses for granted

“Today we have an opportunity to celebrate ourselves as nurses, and I encourage you to acknowledge the good work you are doing. And I include the student nurses as well, because they are our future.”

Prof Matlakala said during the pandemic the world mistakenly took nurses for granted. “They treated us as invisible, and as an inexhaustible resource,” she said, outlining areas such as illness among nurses, fear of the pandemic, death, work overload, and unprecedented changes in nursing environments and nursing education as areas where nurses were “taken for granted as superheroes”.

“The pandemic is over, but the question is: Did the nurses receive any counselling after surviving the pandemic? Did they get special leave to rest? In the nursing practice it is business as usual. In nursing education institutions, they are speaking of catching up on the time lost during the pandemic. Nobody is thinking of exhaustion as a non-communicable disease. Yet, many of our nurses are suffering from exhaustion both mentally and physical. It is thus important that we advocate for wellness for our nurses.”

Protect. Respect. Value

Prof Matlakala said protecting nurses relates to how the government or health system can address the growing nursing shortage and provide positive practice environments, especially with regard to safety in the workplace. She also said the ongoing shortage of nurses is a pandemic that is felt across the globe.

Her message to future nurses is that the profession needs nurses who will be available to confront the many challenges nurses are experiencing. “You need to be assertive and take control of your professional status despite the problems we are hearing. One of the values that we need to have is a positive attitude, which means we need to focus on solutions, not only on problems.”

Celebrating the impact of nursing services

Prof Gert van Zyl, Dean of the UFS Faculty of Health Sciences, welcomed guests and said International Nurses Day celebrates the impact of nursing services in providing high-quality healthcare to patients and improving their overall wellbeing. 

“Nurses play a critical role in the healthcare system, providing care, support, and education to patients and their families. Thank you for your dedication and passion for your profession,” Prof Van Zyl said. “Thank you for all the sacrifices you made to provide the highest level of care and support to people in need in the recent COVID-19 time. Moreso, your contribution to the healthcare industry is immeasurable. We are grateful for everything you do and have done. Keep up the excellent work.”

He added that he believes professional nurses are motivated by many factors, including three main ones: “A desire to help others, a sense of purpose, and the satisfaction of making a difference in people’s life. To motivate nurses for the future, it is important to recognise their achievements, to support them, and to provide opportunities for development and growth.” 

Dr Jeanette Sebaeng, Head of the School of Nursing, said she is privileged to be part of this “very sacred” profession. “I had an opportunity to see life for the first time. I had an opportunity to close someone’s eyes for the first time. I don’t think I would be anything else, even in the next life, other than a nurse.” 

She said when 2020 was declared the Year of the Nurse and Midwife, by year-end the meaning had become grim. “We did not expect that it would be our year in that manner. We lost close to 300 nurses in South Africa due to COVID-19. Even after losing our colleagues, here we are, still strong. That is resilience, and for that I salute you.”

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.
