Research focus on HIV and TB stigma among healthcare workers
Posters reading, “Let’s Stop Stigma” urge healthcare workers to ”Be kind to yourself. Be kind to others.” Pictured here are Dr Asta Rau, Director of CHSR&D and Dr Michelle Engelbrecht, deputy director of the centre.
Researchers working on an internationally funded project are tackling a key occupational health issue: HIV and TB stigma among Free State healthcare workers. They developed and rolled out interventions to decrease stigma and will soon measure the effects. 
In this four-year project, UFS researchers from the Centre for Health Systems Research and Development (CHSR&D) are partnering with Antwerp University and the Free State Department of Health.  

Stigma is like an invisible mark 
A project leader at the CHSR&D, Dr Asta Rau, says most research on stigma in public health focuses on HIV stigma towards patients. Little is done on stigma among healthcare workers themselves. 
Dr Rau says that stigma undermines people’s dignity and causes them suffering. It can even stop them from seeking healthcare. Stigma threatens the health of healthcare workers and the stability of the health system, which is already under strain due to personnel shortages. 

Interventions to make a difference
The research identified two types of stigma - external stigma that can be seen around us, e.g. in the way healthcare workers speak about or treat one another and internal stigma that happens when healthcare workers take this ‘outside’ stigma and turn it inward on themselves. 

Dr Rau says the interventions involve training healthcare workers about what stigma is and how to go about reducing it. “We give them the knowledge and tips on how to communicate when they encounter stigma. It is up to them to then use that to fight stigma.” A communication campaign with posters and branded social marketing materials supports the training. The campaign uses a single slogan: ”Let’s Stop Stigma” and urges healthcare workers to ”Be kind to yourself. Be kind to others."

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
