Dr Asha Malan
Dr Asha Malan, Head of Vascular Surgery in the Faculty of Health Sciences at the University of the Free State (UFS), was elected as the President-elect for the Vascular Society of Southern Africa – the first woman in South Africa to be elected for this position in the Society’s 40-year existence.

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.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
