Dr Kgomotso Moroka
Dr Kgomotso Moroka, Acting HOD: Cardiology in the UFS Faculty of Health Sciences, recently graduated from Maastricht University with a Diploma of Advanced Studies in Cardiac Arrhythmia Management (DAS-CAM).

A staff member from the University of the Free State (UFS) is hopeful her newly acquired skills and knowledge, following her graduation with a Diploma of Advanced Studies in Cardiac Arrhythmia Management (DAS-CAM) and completion of a electrophysiology fellowship, will contribute to the improvement of cardiovascular services in the Free State and Sub-Saharan Africa.

Dr Kgomotso Moroka, the Acting Head of Department (HOD) for Cardiology in the UFS Faculty of Health Sciences, recently graduated with a DAS-CAM in June 2023. This distinctive postgraduate programme is offered by Maastricht University in collaboration with the European Heart Rhythm Association and the European Society of Cardiology. This is a two-year programme and Dr Moroka was part of the third cohort which comprised 32 electrophysiologists selected from over 20 countries worldwide.

Her achievement places her as the sole   DAS-CAM graduate in Sub-Saharan Africa and the Free State region. 
Electrophysiology, which studies the electrical influences and patterns of the heart is vital for treating patients with abnormal heartbeats caused by irregularities in the heart’s electrical pathway, resulting in either unusually slow or fast heartbeats.

Seizing a valuable opportunity

Dr Moroka emphasises that currently, there is a lack of electrophysiology services provided in both the public and private sectors within the Free State. She therefore anticipates that her newly acquired skills and knowledge will play a pivotal role in enhancing and improving the cardiovascular services offered in the province. She is also optimistic about contributing to the establishment of a department dedicated to Electrophysiology Training. 

“I could not pass up the opportunity to engage with, learn and gain insights from seasoned world-class great minds of electrophysiology, who write the books we read and the very guidelines that we utilize in our daily practices. There was also an opportunity to be guided in research and the state-of-the-art cardiac clinical electrophysiology while also obtaining insights into how to develop a cardiac arrhythmia centre, biostatics, health economics, leadership skills and health technology assessment,” Dr Moroka explains regarding her motivation to enrol in the program. 

“It was a challenging and exciting program that allowed participants to engage with the world-renowned experts in electrophysiology not only on a professional but also personal level. This program served not only to educate participants on clinical cardiac electrophysiology but served to empower us to fulfil roles as future leaders in electrophysiology and in our day-to-day roles,” she continued.

Addressing the diverse burden of cardiac diseases

Dr Moroka believes that this qualification will significantly contribute to local efforts to establish and develop a much-needed unique service, thereby advancing her career development locally and on the international platform. This qualification enables her to expand her clinical research pursuits on multiple fronts.

Dr Moroka underscores the substantial burden of ischemic heart disease with the associated risk factors such as uncontrolled high blood pressure, diabetes, elevated cholesterol levels and smoking. “There is a measurable burden of heart failure and valvular heart disease. In addition, from the research that we hope to embark upon, we hope to clearly define the burden of rhythm problems such as atrial fibrillation and other arrhythmias which are serious conditions. With the available skills and knowledge, we can begin to offer alternative adjunctive treatment that would have a significant positive effect on the morbidity and/or mortality of our patients.”

Dr Moroka points out that with the advent and advances in machine learning and digital health technology, we are in an exciting era of possibilities of obtaining valuable biological data and biometric parameters that would assist in the reduction of risk and prevention of a diversity of cardiovascular diseases and to guide clinical practice guidelines. 

“The current focus is risk reduction, prevention of cardiovascular diseases and the establishment and development of personalized health care, with a growing interest in cardiovascular genetics and gene therapy.  Who knows what the future will bring, but for now the focus is to work towards good health and disease alleviation,” she says.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
