The Centre for Health Systems Research and Development (CHSR&D) in the Faculty of the Humanities at the University of the Free State (UFS) has been at the forefront of research on the societal and human impact of COVID-19. The CHSR&D has investigated the effects of the pandemic on, among others, post-traumatic stress and the coping strategies of nurses, and is currently undertaking a research project looking at vaccine literacy and acceptability in South Africa through an online survey, which has already attracted more than 9 500 respondents.

Prof Michelle Engelbrecht
, Director of the CHSR&D, says it is important not to lose sight of the impact that the pandemic has had on society and individuals. “It has affected all aspects of life, caused economic disruptions, and posed immense challenges to both public and private healthcare, food systems, education, and employment,” she says. For the CHSR&D researchers, it is important to understand the health and socio-economic impacts in order to inform interventions and policy. 

Established in 1993, the CHSR&D stems from a rich tradition of research and training in medical sociology and sociology of health. As a centre, they generate and disseminate research findings and information on health and health systems to promote transformation in policy and practice in the South African healthcare system.

A study on the impact of the pandemic on nurses

In early 2021, the CHSR&D completed a project on the post-traumatic stress and coping strategies of South African nurses during the second wave of the COVID-19 pandemic.  This study was one the first to examine how the pandemic influenced the post-traumatic stress and coping strategies of nurses in the country. It was found that 44% of nurses were experiencing post-traumatic stress disorder (PTSD), which was comparatively higher than their counterparts in other countries. Furthermore, a lack of preparedness to manage COVID-19 patients, poorer health, and avoidance coping mechanisms were associated with increased PTSD in nurses. Nurses voiced a need for emotional support and empathy from their managers. 

Some of the intervention strategies recommended by the nurses included emotional, psychological, and debriefing sessions focusing on positive coping strategies to address stress effectively; positive and open communication between managers and their subordinates; psychological support through the Employee Assistance Programme and occupational health units; and an uninterrupted supply of quality personal protective equipment. The findings of this project were shared with the Free State Department of Health (FSDoH).

Ongoing research projects

As of 1 September 2021, the CHSR&D commenced with a national online survey on COVID-19 vaccine literacy and acceptability. While there are a number of studies looking at the uptake of COVID-19 vaccines, Dr Gladys Kigozi notes that “this study is novel, as there is a lack of information about vaccine literacy, which may be defined as the degree to which people have the capacity to obtain, process, and understand basic health information and services to make appropriate health decisions.”. The anonymous online survey is available through social media and the Moya messaging application.
 
The CHSR&D, together with a team from the FSDoH and the World Health Organisation, are also collaborating on a project looking at the impact of COVID-19 on essential health services, mortality in hospital-admitted patients, and outcomes in patients with a history of tuberculosis. According to Prof Christo Heunis, “The COVID-19 pandemic has become infamous for crippling healthcare systems. Resources and staff are being diverted to test and provide treatment for people with presumed or diagnosed COVID-19, and thus some other healthcare services are being compromised to meet the demands of caring for COVID-19 patients.” It is thus imperative to measure the impact of the pandemic on essential health services and treatment outcomes. 


Interdisciplinary research project focusing on the health and well-being of vulnerable families 

The CHSR&D, together with the UFS Department of Social Work, the School of Nursing, and the Disaster Management Training and Education Centre for Africa (DiMTEC), will commence with a study investigating the impact of COVID-19 on the health and well-being of vulnerable families in the Mangaung Metropolitan area. This project is funded by a UFS interdisciplinary grant.  While the study is limited to the Mangaung Metropolitan area, it has the potential to inform health and social policy in other metropolitan areas in South Africa – particularly with regard to preparedness and management of pandemics such as COVID-19.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
