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.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
