There is no doubt that an institution like the University of the Free State (UFS), with its calibre and pedigree, needs a PET/CT machine (medical-imaging device that simultaneously and clearly reveals both anatomical details and metabolic processes within the body), particular in oncology, in improving the management of patients.

This is according to Prof Willy Vangu, Chief Specialist and Head of Nuclear Medicine at the University of the Witwatersrand, who was a guest lecturer on 8 September 2022 at the Department of Nuclear Medicine at the UFS.

Positron emission tomography (PET) is a type of nuclear medicine imaging modality that measures the metabolic activity of the cells of body tissues. PET imaging is useful in the evaluation of patients with neurological, cardiac, infection, inflammation, and most importantly oncological conditions. Through its ability to detect metabolic changes very early, it can detect disease conditions that might not be easily detected on other forms of anatomical imaging.

Role of PET/CT in different clinical scenarios

In his lecture, Prof Vangu talked about the role of PET/CT in different clinical scenarios. By giving practical examples, he explained the role of PET/CT in different aspects of clinical medicine, including brain imaging for dementia, movement disorder and cerebrovascular reserve.

“Looking at dementia, we will focus on one of diseases that is today becoming a major source of health concern, Alzheimer's disease. The latest Alzheimer's report that was published in 2018 stated that there are 50 million individuals currently suffering from Alzheimer's. They forecast that in 30 years we are going to have more than 150 million people suffering from this disease. PET/CT imaging can identify very early the typical patterns associated with all the different types of dementias, including Alzheimer's disease…”

For cardiac application, Prof Vangu said there are so many indications for PET/CT in cardiac imaging. One of the most important is the assessment of myocardial viability, in patients who have suffered from cardiomyopathy due to ischemic heart disease. PET/CT offers a noninvasive method of identifying viable myocardium that would benefit from revascularisation, with a very high diagnostic accuracy.

Prof Vangu, who is also the head of nuclear medicine at the Charlotte Maxeke Johannesburg Academic and Chris Hani Baragwanath hospitals as well as head of the department for radiation sciences at the University of the Witwatersrand, said PET has been around for many years and is not something new. However, in clinical practice, PET imaging became significant with a breakthrough that occurred with the production of the glucose analogue tracer, 18F-fluorodeoxyglucose (FDG). This tracer in PET/CT imaging has revolutionised the management of cancer patients for the oncologist. It offers the ability of more accurate cancer staging, assessment of treatment response, assessment of disease recurrence and in some situations, surveillance. It has the ability to predict early which cancer patients will benefit from a particular drug, thereby giving the oncologist an idea on either to de-escalate treatment or change to a second line regimen very early on in the management.

PET/CT came onto the market only in the year 2001, when it was launched for the first time by David Townsend (a physicist) and Ronald Nutt (electrical engineer). As at today, almost every institution in the country has at least one PET/CT machine.

“Looking at clinical applications, which is really the crux of the lecture today, there are so many clinical applications to talk about. You need a full week of a PET/CT symposium to go through all of them (and) maybe that might not even be enough. We can at least from this talk have an idea on how PET/CT can be applied in clinical medicine,” said Prof Vangu.

No other road for the university but to get a PET/CT machine

He also showed the impact and results that PET/CT imaging had in the management of infection and inflammation including TB. He said the role of PET/CT in TB is for monitoring of treatment, identification of extrapulmonary TB and prognosis.

In concluding his lecture, he said there is no other road for the university but to get a PET/CT machine. “There is no argument about it. The institution needs it to improve the management of patients, especially the oncology and cardiology patients. Confidently making the decision on which patients to treat, how to treat them, identifying and evaluating their true response to therapy requires a PET/CT machine.

“I am happy to hear that the policy- and decisions-makers in the province and the university are looking forward to having a PET/CT machine,” he said later.

Dr Osayande Evbuomwan, nuclear medicine specialist and Senior Lecturer, and Dr Gerrit Engelbrecht, Clinical Head of the Department of Nuclear Medicine at the UFS, are both looking forward of having a PET/CT in the department because in addition to its use in clinical setting, it has a huge role to play in research and training postgraduate students, as PET/CT imaging makes up a huge chunk of the postgraduate training curriculum

UFS Communication and Brand Management receives two prestigious international awards

2015-07-07

Lelanie de Wet, Lacea Loader and Leonie Bolleurs

The Department of Communication and Brand Management at the University of the Free State (UFS) received two of the six Gold Quill Awards – that were awarded to South African companies and institutions - at the International Association of Business Communicator’s (IABC) Excellence Gala ceremony in San Francisco, US on 15 June 2015.

The awards ceremony formed part of the 2015 IABC World Conference, which took place from 14-17 June 2015. The department received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook and a Gold Quill Merit Award for the B Safe Take Action campaign.

From the 15 countries that entered, a total of 120 Gold Quill Excellence awards and 189 Gold Quill Merit awards were awarded. Other South African award winners included Barclays Africa Group Limited, Mediclinic and the Cape Peninsula University of Technology (CPUT).

This is the second year in a row that the UFS has been recognised by the IABC for its communication projects. In 2014, the department was awarded the Jake Wittmer Research Award for a Stakeholder Perception Audit conducted in February 2014. The audit was considered – by the IABC - as one of the best breakthrough strategies used by a university to measure the perceptions of its stakeholders.This made the UFS the first tertiary institution in Africa to receive the research award. The stakeholder perception audit also received an Africa Gold Quill in 2014.

"Being recognised by a global association such as the IABC for the second time, is a great honour and I am very proud of what my colleagues have achieved by entering the two campaigns. Winning the awards is a true indication of what can be done when a team of expert communicators is committed towards engaging their target audiences with campaigns that speak of quality and innovation. The fact that the UFS is one of only two tertiary education institutions in the country to receive these prestigious awards, makes it even more special," said Lacea Loader, Director: Communication and Brand Management at the UFS.

IABC World and Africa conferences 2015

The IABC is a global membership association with a network of 12 000 members in more than 80 countries, representing many of the Global Fortune 500 companies. It serves professionals in the field of business communication, bringing together the profession’s collective disciplines.

With the theme: Changing landscape: Informing the future, the 2015 world conference was attended by over 1 200 delegates from across the world. Delegates were offered an opportunity for learning, discovering, and connecting. Loader also made a presentation entitled ‘Award-winning measurement endorses sound reputation management strategy’ at the world conference.

The department will also be receiving two Africa Gold Quill Awards from the Africa chapter of the IABC for the same campaigns on 30 July 2015 in Johannesburg.

UFS #FaceOfFacebook Campaign

The university received a Gold Quill Excellence Award for its social media campaign, UFS #FaceOfFacebook. This initiative originated in the university’s commitment to its Human Project, which sets the standard for good behaviour and care.

Lelanie de Wet, Manager: Social Media and Website Content and project leader of UFS #FaceOfFacebook, said the project was born from the need to communicate with students. Thus a virtual friend, #FaceOfFacebook, was created. “Yearly auditions are being held to choose the new face representing the UFS on Facebook. Short video clips of the #FaceOfFacebook – whether it is attending events or communicating important messages - are posted on the UFS Facebook page. The successful candidate holds the title #FaceOfFacebook for 12 months.

“When I look at a campaign such as #FaceOfFacebook, from the time it took its first tentative steps in 2013, and see how it inspired staff and students alike, my heart swells with pride. Often you can see the impact you have made only in retrospect. The ripples you send into the world will inevitably create waves,” she said.

B Safe Take Action Campaign

The B Safe Take Action campaign of the university received a Gold Quill Merit award from the IABC.

The campaign was activated in September 2013. “It targeted on- and off-campus students and staff, aiming to create social ownership of personal safety, and to raise awareness of the safety measures put in place by the university,” said Leonie Bolleurs, Manager: Internal Communication and project manager of the campaign.

The campaign looked at a number of safety aspects, focusing not only on crime but also on being safe from road accidents and stress/burnout.

It is the second time this year that the BSafe campaign has been recognised for its innovative strategy. Earlier this year it received a PRISM Award (Gold) from the Public Relations Institute of Southern Africa (PRISA). The annual PRISM Awards are about recognising and celebrating great public relations campaigns.
