Social media discussions have provided a lens on how people are dealing with and talking about COVID-19. This has given risk communication new insights into online audiences.

The lingering effects of the COVID-19 pandemic on society presented the experts at the University of the Free State (UFS) with an opportunity – to conduct a scientific study by analysing our social media data in order to assist government health communicators to reflect on their communication strategies and, in turn, gain new perspectives from the general social media user (public). 

The study – led by Herkulaas Combrink, a data and medical scientist in the UFS initiative for Digital Futures, and Prof. Katinka de Wet, medical sociologist in both the UFS initiative for Digital Futures and the Department of Sociology at the UFS – uses “real-time snapshots of online interactions as a means to augment more traditional methods of conducting research on a given topic; in this case, responses to COVID-19”, said Combrink. 

The findings and ongoing work of the research project were presented to the Parliamentary Portfolio Committee on Communications. “During this meeting, critical engagement took place around risk communication and areas where we can strengthen this research,” said Combrink. Several international influential risk communicators on the African continent were present. 

Digital science at the forefront 

The opportunity to pursue this study was the result of Herkulaas Combrink’s secondment to the Free State Department of Health (FSDOH), where he identified the need to develop additional analytics for the already existing processes in risk communication in order to assist various communication strategies linked to developments regarding COVID-19 infections.  

Combrink also said “because the analysis of social media data does not normally form part of the traditional toolbox of investigation for this type of work, this novel application serves as an addition to the already existing communication analytics”. This research project will strengthen the level of cooperation between the UFS, other institutions, and the FSDOH to “synergistically strengthen communication strategies in relation to COVID-19”. 

By looking at how new knowledge around COVID-19 is developing the method (of analysing social media data), is to stay abreast of trending and burning issues on open-source social media platforms. “It is important to conduct this work using well-defined scientific methodology to extract, explore, analyse, and report on the data,” Combrink says. 

Given the rapidity with which new knowledge around COVID-19 is developing all over the globe, this method lends itself to staying abreast of emergent and burning issues that are trending on open-source social media sites. 

Variety of stakeholders needed

The magnitude of the research study required the involvement of stakeholders from different institutions. “A variety of stakeholders from different institutions are needed not only to contextualise the data, but also to provide social and technical input to solve the problem,” Combrink said.  

Experts included in the project are Dr Vukosi Marivate from the Department of Computer Science at the University of Pretoria, Dr Ming-Han Mothloung from the Department of Community Health at the UFS and the FSDOH, and Dr Samuel Mokoena, Priscilla Monyobo, Mondli Mvambi, and Elke de Witt from the FSDOH. “Without this core team, the work would not have been contextually relevant,” Combrink said.

Medical team performs first hybrid procedure in the Free State
2014-12-08

The days when a heart operation meant hours in an operating theatre, with weeks and even months of convalescing, will soon be something of the past.

A team of cardiologists from the University of the Free State’s (UFS) Faculty of Health Sciences once again made medical history when they performed the first hybrid procedure in the Free State.

The Department of Paediatric Cardiology, in conjunction with the Department of Cardiothoracic Surgery, performed this very successful procedure on a 45-year-old woman from Kuruman.

During the procedure of 30 minutes, the patient’s thorax was opened up through a mini thoracotomy to operate on the beating heart.

“The patient received an artificial valve in 2011. Due to infection, a giant aneurism developed from the left ventricle, next to the aorta. Surgery would pose a very high risk to the patient. Furthermore, her health was such that it would contribute to problems during open-heart surgery,” explains Prof Stephen Brown, Head of the UFS’s Department of Paediatric Cardiology.

“After the heart was opened up through a mini thoracotomy, the paediatric cardiologists performed a direct puncture with a needle to the left ventricle cavity. A Special sheath was then placed in the left ventricle to bypass the catheters. Aided by highly advanced three-dimensional echocardiography and dihedral X-ray guidance, the opening to the aneurism, located directly below the artificial aorta valve, was identified and the aneurism cannulated.”
 
During the operation, a special coil, called a Nester Retractor, was used for the first time on a patient in South Africa to obtain stasis of extravasation and ensure the stability of devices in the aneurism.

“This is highly advanced and specialist work, as we had to make sure that the aneurism doesn’t rupture during manipulation and the devices had to be positioned in such a way that it doesn’t cause obstruction in valve function or the coronary artery. The surgical team was ready all the time to switch the patient to the heart-lung machine should something go wrong, but the procedure was very successful and the patient was discharged after a few days.”
