Maricél van Rooyen, Project Manager for Research Information Management System (RIMS) and Research Ethics Adviser in the Directorate Research Development (DRD) at the University of the Free State (UFS), is the Programme Coordinator for a first-of-its-kind Southern African Research and Innovation Management Association (SARIMA)/ COP webinar on Environment and Biosafety Research Ethics.

The University of the Free State (UFS) is playing host to a first-of-its-kind webinar on Environment and Biosafety Research Ethics later this month with Maricél van Rooyen, Project Manager for Research Information Management System (RIMS) and Research Ethics Adviser in the Directorate Research Development (DRD), playing a pivotal role.

The webinar, which is part of the Eastern Region Community of Practice (COP), is taking place on 20 August. The target market for this virtual workshop is Biosafety and Environmental Research Ethics Committee (REC) chairpersons and members, professionals including research management professionals, administrators, research compliance managers and advisers, and research directors in Southern Africa and beyond.

Van Rooyen will be the Programme Coordinator for this Southern African Research and Innovation Management Association (SARIMA)/ COP Research Ethics Webinar, while Prof Robert Bragg, chairperson of the UFS Environmental and Biological Research Ethics Committee (EBREC), will give a presentation on the establishment of an EBREC.

The UFS, Stellenbosch University and the University of the Witwatersrand, form part of the COP which is a SARIMA (Southern African Research and Innovation Management Association) initiative to assist and share research ethics questions between institutions to empower research management and ethics compliance. SARIMA assisted with the online hosting and advertising of the webinar.

Purpose of the webinar

“Environment and Biosafety Committees in South Africa are a new idea, and only a few institutions in the country have such a committee. The UFS and the other institutions that will present at the workshop, take a leading role because they have already registered committees in place. We want to share and assist with establishing and operating such committees,” says Van Rooyen.

According to her, the need for the webinar arises from the upsurge of research and innovation in biotechnology and related fields over the past two decades that has led to exciting new discoveries in areas such as the engineering of biological processes, gene editing, stem cell research, CRISPR-Cas9 technology, Synthetic Biology, recombinant DNA, LMOs and GMOs, to mention only a few.

These advances, however, have generated concerns about biosafety, biosecurity and adverse impacts on biodiversity and the environment, leading to the establishment of Research Ethics Committees (RECs) at Higher Education and Research Institutions dedicated to reviewing research with implications for biosafety and the environment.

These EBRECs are in the early stages of their establishment and formalisation in South Africa, and there is much uncertainty about their composition, scope, procedures of decision-making and the principles that should guide their deliberations and assessments.

Leading the charge

The UFS took the lead in South Africa in ensuring international ethical compliance in this extended area of research, by establishing its own Environmental and Biological Research Ethics Committee (EBREC) six years ago. The UFS EBREC is one of only two such ethics committees at a South African university that combines the biosafety committee with environmental and biological research ethics to ensure ethics compliance in these fields.  The initiative started with Van Rooyen and her RIMS EthicsTeam, (Willem Kilian and Amanda Smith). The university is again taking charge with this webinar, which is a first of its kind.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
