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."

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
