Public lecture focuses on diversity as foundation for equality

The Free State Centre for Human Rights at the University of the Free State (UFS) held a public lecture at the Bloemfontein Campus on 30 January 2018 titled Putting religion in brackets: the importance of diversity in the public square by Prof Iain T Benson, Professor of Law at the University of Notre Dame in Sydney, Australia, and, for the past seven years, extraordinary Professor of Law at the UFS.

Conflict between religion and modernity

According to Prof Benson, there have been attempts to exclude so-called old-fashioned ideas from modernity. He gave examples of political and moral objections to public money being spent on religious education by schools, and the prevalence of terminology that stigmatises alternative opinions that may be based on religion, such as “homophobia”. He also referred to an instance in which the accreditation of a Canadian Christian university was challenged because its covenant explicitly rejected certain practices, such as extramarital relationships and same-sex marriage – the objections centred on an institution with such views receiving public benefits.

The challenge of inclusion in a growing secular society
Last year, a South African court found that schools may not promote a single faith to the exclusion of others. “According to the constitution, we have the right to hold religious beliefs. However, there are limitations on religious practices. Each society must draw a line,” he said. In the South African case, he explained, “the court rejected a blanket exclusion of religion in schools. If religion is a right, how can it be voted out of existence?”

Prof Benson argued that the ideology of secularism, the separation of church and state, is making inroads into how we understand religion. If agnostic or atheist viewpoints are accepted in the public sphere, it should not mean that religious beliefs should be abolished. “A diversity of beliefs should be accommodated and every citizen, whether religious or not, may be a part of public life,” he said. He concluded by saying that we lived in a particularly difficult time for a religious believer in the public sphere.

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
