A passion for evidence-based medicine and the notion of value in healthcare is what drives Dr Anchen Laubscher, our guest in the fifth episode of the Voices from the Free State podcast. Anchen is driven to ensure that healthcare is scientifically proven, of high quality, cost effective, and tailored to a patient’s needs.  

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series.  Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021.  Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

Our podcast guest

Anchen joined Netcare in 2007 as an aeromedical doctor and has been with the group for almost 14 years. As Group Medical Director of Netcare Ltd, Anchen is responsible for the strategic oversight and operational execution of all clinical and quality-related matters across the different divisions of Netcare. Leading a team of subject matter experts, Anchen oversees the group’s key deliverables related to the value of care, encompassing quality outcomes, patient safety, patient experience, and episode cost efficiency, with all components of ‘value’ digitally enabled and data driven.

Anchen is a member of the Hospital Association of South Africa (HASA) subcommittee for Clinical Quality and the South African Committee of Medical Deans (SACOMD) initiative, which was constituted to address the human resource dilemma specifically related to the training of doctors in South Africa. She is a Council member of the University of the Free State, where she also serves on the Senate and holds director appointments in the Mother and Child Academic Hospital (MACAH) Foundation, the My Walk My Soul collaboration between Netcare and Adcock-Ingram and the University of Cape Town Medical Centre Ltd.  Anchen played a pioneering leadership role in South Africa’s response to the 2014 global Ebola Virus Disease (EVD) outbreak, which continues in her role as Gold Command in Netcare and as member of various national committee and advisory structures related to the COVID-19 pandemic preparedness and response. For her role in the South African EVD response, she was recognised with an honorary award from the South African Military Health Services (SAMHS).

Clinically, Anchen continues to contribute to the specialty of emergency medicine, specifically pre-hospital and aeromedicine. She continues to be involved at her alma mater through ad hoc lecturing in electives, research support at GIBS, and participating in health-care courses and conferences such as the 2020 Healthcare Industry Update and Innovation Conference.

Stay tuned for episode six to be released on 5 July 2021.

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.
