Dr Martin Mandew believes that the devastating impact of the pandemic will be felt for quite some time.

A Human Rights view by Dr Martin Mandew, Campus Principal of the UFS Qwaqwa Campus


It is not easy to discern the silver in the lining of the pandemic cloud that we have been living under over the past twelve months. I hazard to say that for those at the bottom of the socio-economic heap, those whose daily life is nothing but a gut-wrenching struggle to scrape together a semblance of a meal, talk of silver linings is foreign to their experience. The pandemic has shown just how low leaders can sink when elected public officials steal and redirect food parcels – meant for the poor and destitute – for their own personal consumption, for those close to them through family ties, through friendship and through political affiliation, or sell it for personal financial gain. The intended relief measures, designed to be non-partisan, are used instead to promote the socio-political divisions that already exist in the community. The unspoken mantra seems to be: If you look like me, if you think like me, if you believe like me, if you speak like me, if your political beliefs are like mine, only then can you expect me to do the public good for you and for your benefit that I have been elected to do, even though I get paid for carrying out this very important task. Talk of unity is rich in such an environment.

Nation-building
The devastating impact of the pandemic will be felt for quite some time. In the next twelve months we must, despite the enormous challenges ahead, re-imagine and craft a future of unity, where personal, political, ethnic, racial, gender, economic, and other differences will not stunt and sabotage efforts of socio-economic renewal. This Human Rights Month is a stark reminder for us to go back to our foundations as a South African nation. It is a time to press the reset button in the agenda of nation-building. Nation-building is not achieved through a fiat, a ‘let-it-be-so’ declaration. While taking the necessary steps to rebuild a battered economy, nation-building also entails making the necessary investments in social support to alleviate the impact of the pandemic on the most vulnerable in society, while also ensuring that the white-collared hyenas are kept at bay. The right to health care, food, water, and social security is enshrined in the Constitution.  

The future
Nation-building also entails making bold investments in education, taking care that as budgets are re-organised, re-prioritised and reduced, the education sector is not made a casualty of austerity measures. We must not falter to build our nation on a solid foundation of education, ensuring that we make the right investments and the required interventions in this very critical sector. There are components in the sector that are weak and glaringly under-resourced, such as early childhood development, as well as post-school technical and artisanal training. We need to strengthen these as part of building a firm foundation for our fledgling nation. This is a very important asurance for the future of our nation. Only an educated nation is best equipped to confront the challenges that lie ahead, such as those that the COVID-19 pandemic has thrust upon us. The right to education is enshrined in the Constitution.

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.
