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."

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
