Dr Asha Malan, the Head of Vascular Surgery in the Faculty of Health Sciences at the University of the Free State (UFS), has made history by being elected as the President-elect for the Vascular Society of Southern Africa. This milestone marks the first time a woman in South Africa has attained this prestigious position in the Society’s 40-year existence.

Dr Malan, an exemplary surgeon and a trailblazer, is not only one of the seven qualified female vascular surgeons in the country but also holds the distinction of being the youngest and first female to head an academic unit in South Africa. Her election took place at the recently concluded 2023 Vascular Society of Southern Africa (VASSA) Congress, a significant event for the UFS Division of Vascular Surgery, under her leadership as the congress chairperson. The Congress was hosted at the Lord Charles Hotel in Somerset West, Cape Town, in collaboration with the World Federation of Vascular Societies (WFVS) and the European Society of Vascular Surgery (ESVS).

Reflecting on her achievement, Dr Malan remarked, “It is not only an honour to be the first woman in 40 years to lead this Society, but an honour to be elected for this role. VASSA has established a well-recognised international footprint and has invested significantly in promoting the growth of vascular surgery as a specialised surgical field in South Africa.”

She added, “Representing the Society in this capacity allows me to continue serving its members and the Southern African community, creating awareness not only about the growing burden of vascular diseases but also the advancements in the field to address these challenges.”

First gathering since 2018

The 2023 VASSA Congress marked the first gathering of Vascular Surgery specialists in South Africa since 2018, a gap caused by the pandemic. The event was attended by approximately 300 delegates, including nursing staff, radiographers, vascular technologists and other allied health professionals with a keen interest in Vascular Surgery. VASSA sponsored nursing staff, a radiographer and a vascular technologist from Universitas Academic Hospital to attend the meeting.

The high-quality, four-day programme featured talks from local and international experts covering various aspects of vascular surgery, such as aortic surgery, peripheral arterial disease, carotid pathology, dialysis access and venous disease. Notably, the academic programme saw the participation of 32 international speakers. Guest speaker, Dr Imtiaz Sooliman, the founder of the Gift of the Givers Foundation, delivered an inspiring talk during the ethics session titled “Humanitarian efforts within the Healthcare Sector – Sharing the Responsibility”.

Presentations

During the Congress, Dr Malan and several Vascular Surgeons from the Department of Surgery represented the UFS. Dr Malan shared her experiences in developing a dedicated unit for the management of complex thoraco-abdominal aneurysmal disease, a talk that garnered significant interest and applause from both local and international experts.

In her presentation, Dr Malan took the audience through her journey to several different international units to gain expertise in open thoraco-abdominal aortic surgery. She also highlighted the UFS Division of Vascular Surgery’s achievement of being the first academic Vascular Surgery unit in South Africa to perform a complex endovascular aortic aneurysm repair. In addition, Dr Sam Letsoara and Dr Wikus Mulder, Vascular Surgery Fellows in training, presented the local evolution of endovascular therapy as well as an audit of endovascular management of blunt thoracic aortic injury at Universitas Academic Hospital, respectively. Dr Sam Agbo, a registrar in the Department of Surgery, also presented his MMed research, evaluating the cost of open versus endovascular management of abdominal aortic aneurysms.

The Congress significantly contributed to the promotion of Vascular Surgical awareness and care, not only in South Africa, but across Africa and globally. It stands as a testament to the dedication and expertise of the Division of Vascular Surgery at the University of the Free State.

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.
