Prof Mamello Sekhoacha, Associate Professor from the Department of Pharmacology in the Faculty of Health Sciences, was appointed by Dr Zweli Mkhize, Minister of Health, as the new chairperson of the National Health Research Ethics Council of South Africa (NHREC).

A researcher in the field of drug discovery and development at the University of the Free State (UFS) has been appointed by Dr Zweli Mkhize, Minister of Health, as the new chairperson of the National Health Research Ethics Council of South Africa (NHREC).

Prof Mamello Sekhoacha, Associate Professor from the Department of Pharmacology in the Faculty of Health Sciences, was appointed as a member of the NHREC council in 2013, and later became the chairperson of the NHREC’s Norms and Standards Committee responsible for developing and revising guidelines for health research. Prof Sekhoacha was appointed deputy chairperson of the council in 2018 and has played an integral part in setting ethical standards for conducting health research in the country.

 Responsibilities of the NHREC

The NHREC is the national statutory body responsible for the governance and advancement of health research ethics in South Africa. Some of the responsibilities of the council are to set ethical norms and standards for health research by developing and revising the guidelines pertaining to health research; to promote and monitor compliance with existing regulations by health research ethics committees; and to build capacity in research ethics committees through robust registration and audit processes.

These responsibilities of the NHREC rest on the need to ensure ethical integrity in research involving human participants and animal subjects, and that research is based on sound scientific and ethical principles.

“It is an honour for me to serve on the NHREC for the third term. The NHREC has achieved remarkable outputs over the past three years, and I believe, given the current composition of the council members, this momentum will not be lost. One of the goals of the NHREC is to further broaden the scope of the ethics in health research guidelines from ‘biomedical research’ to ‘health-related research’ to ensure that adequate guidance is provided for those in health-related disciplines, as a response to the changing environment of research involving humans and the broader meaning of health research.” 

“We need more comprehensive guidelines with nuanced commentaries to indicate how the ethical principles that emanated from biomedical research involving humans, could be effectively implemented in other disciplines of health-related research,” says Prof Sekhoacha. 

Global paradigm shift in role and integration of ethics in health research

Having been a council member since 2013, Prof Sekhoacha, whose training spans from pre-clinical laboratory experimentation, the use of animals in research, clinical trials, and working with indigenous communities, says there is a global paradigm shift in the role and integration of ethics in health research in almost all aspects of research, with an increased emphasis on the scientific and social value of research: the prospect of generating the knowledge in a manner that protects and promotes people's health. Considerations of the NHREC go beyond developing ethical guidelines or ensuring the efficient functioning of the ethics committees, to raising awareness among research institutions and researchers to continually promote ethically sound research conduct. 

The subject of ethics in health research is pivotal and reflective of the values of both the institution and the country at large. 

UFS uses Prof Sekhoacha’s expertise on ethics

Prof Sekhoacha is also a co-opted advisory member in the Senate Research Ethics Committee of the UFS and facilitates workshops and seminars on research ethics offered by the Postgraduate School.

Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, says it is a great honour for the UFS that Prof Sekhoacha has been elected chair of the NHREC.  “The NHREC governs the research ethics processes in South Africa, and it is strategically important for the UFS to now have one of our own academics play such a nationally important role.  We have been using Prof Sekhoacha’s expertise on issues of ethics and we are looking forward to working with her to continue to better our own ethics processes.”

The conservation strategy of the black rhino in Africa needs to change in order to protect the species from extinction, a group of international researchers has found. The study that was published in the Nature Scientific Reports reveals that the species has lost an astonishing 69% of its genetic variation. 

South African researchers took part 

The researchers, which included local researchers from the National Zoological Gardens of South Africa (NZG), have highlighted the fact that this means the black rhino is on the brink of extinction. "We have found that there is a decline in genetic diversity, with 44 of 64 genetic lineages no longer existing," said Prof Antoinette Kotze, the Manager of Research and Scientific Services at the Zoo in Pretoria. She is also affiliate Professor in the Department of Genetics at the University of the Free State and has been involved in rhino research in South Africa since the early 2000s.  

DNA from museums and the wild 
The study compared DNA from specimens in museums around the world, which originated in the different regions of Africa, to the DNA of live wild animals. The DNA was extracted from the skin of museum specimen and from tissue and faecal samples from animals in the wild. The research used the mitochondrial genome.

"The rhino poaching ‘pandemic’
needs to be defeated, because
it puts further strain on the genetic
diversity of the black rhino.”


Ability to adapt 
Dr Desire Dalton, one of the collaborators in the paper and a senior researcher at the NZG, said the loss of genetic diversity may compromise the rhinos’ ability to adapt to climate change. The study further underlined that two distinct populations now exists on either side of the Zambezi River. Dr Dalton said these definite populations need to be managed separately in order to conserve their genetic diversity. The study found that although the data suggests that the future is bleak for the black rhinoceros, the researchers did identify populations of priority for conservation, which might offer a better chance of preventing the species from total extinction. However, it stressed that the rhino poaching ‘pandemic’ needs to be defeated, because it puts further strain on the genetic diversity of the black rhino. 

Extinct in many African countries 
The research report further said that black rhino had been hunted and poached to extinction in many parts of Africa, such as Nigeria, Chad, Cameroon, Sudan, and Ethiopia. These rhino are now only found in five African countries. They are Tanzania, Zimbabwe, Kenya, Namibia, and South Africa, where the majority of the animals can be found.
