Research room
Prof Corinna Walsh from the UFS Department of Nutrition and Dietetics explains how the PEA POD® infant body composition analyser works. Dr Balekile Mzangwa, CEO of Universitas Academic Hospital, and Dr Grace London, Chief Director: District Health services at the Free State Department of Health, listens in.

In a significant stride toward improving maternal and child health in the Free State, the Universitas Academic Hospital, in collaboration with the Faculty of Health Sciences at the University of the Free State (UFS), has launched an innovative Research Room which houses the PEA POD® infant body composition analyser and the Dual-Energy X-ray Absorptiometry (DXA) machine used to assess body composition and bone mineral density.

The initiative, which marks a new era in neonatal care and research, aims to integrate cutting-edge technology into routine clinical care. The PEA POD®, a non-invasive device that uses air displacement plethysmography, allows for precise measurement of fat and fat-free mass in newborns – offering a more accurate assessment of growth and nutritional status than traditional methods. 

The research room is a newly renovated and dedicated space adjacent to the maternity and neonatal units, ensuring quick, safe access to the newborns in the hospital. Two full-time MSc Dietetics students have been trained to perform the PEAPOD® assessments and colleagues from Radiography will perform the DXA assessments. This work lays the foundation for an ongoing maternal and infant body composition database –  a valuable resource for research, clinical care, and policy guidance.

Aligned with national health priorities

According to Prof Corinna Walsh from the UFS Department of Nutrition and Dietetics, this initiative is the result of a multidisciplinary collaboration across Paediatrics and Child Health, Obstetrics and Gynaecology, Radiography, Nutrition and Dietetics, to mention just a few of the collaborators. They are optimistic about the dual impact of this project as it advances academic and clinical research in early-life nutrition and growth as well as enhancing patient care at Universitas Hospital – bringing measurable benefits to mothers and their babies, she said. 

“This initiative is well aligned with national health priorities. According to the South African Early Childhood Review 2024, malnutrition in all its forms remains a significant challenge with short- and long-term consequences for mothers and their babies, especially during the first 1 000 days of life, from conception to the second birthday.

“We know from global and local evidence that growth patterns established during early life have profound and lasting effects on an individual’s health, development, and well-being. Our work at the University of the Free State has focused on the nutritional status of pregnant women and the early environments to which infants are exposed, both during and after pregnancy,” said Prof Walsh. 

However, she continued, in previous studies, they faced a significant challenge: the lack of specialised equipment to accurately measure infant body composition. Traditional measures such as weight and length provide only part of the picture.

 

New possibilities in healthcare, science, and service

Dr Mzangwa said the day not only marks the unveiling of state-of-the-art technology, but the beginning of a new chapter in how they will care for and understand the youngest and most vulnerable patients. The PEA POD® and DXA, which is now housed just steps away from the maternity and neonatal wards, symbolise a shared vision between the hospital and the Faculty of Health Sciences at the UFS: a vision grounded in evidence-based care, cutting-edge research, and above all, compassion.

“We express our sincere appreciation to everyone who supported this initiative. We also acknowledge the dedication of all the collaborating departments – Paediatrics and Child Health, Obstetrics and Gynaecology, Radiography, Nutrition and Dietetics –  and thank Prof Corinna Walsh and Dr Lizzy Tabane for their leadership and insight.”

Prof Janse van Vuuren, said: “Today, we do more than open a physical space. We open the door to new possibilities in healthcare, science, and service to the people of our province. It is a shining example of what can be achieved when government and academia come together, united by a common purpose – to improve lives through knowledge, innovation, and care.”

The technologies that will be used in this facility are more than just advanced instruments, they are tools that allow medical staff to better understand the human body in its earliest and most vulnerable stages, as well as throughout the lifespan. With this understanding comes the ability to make informed decisions, to intervene earlier, and to tailor care in ways that truly meet the needs of our patients, said Prof Janse van Vuuren.

“This space is more than a research centre. It is a testament to our commitment to evidence-based care. It is a place where data meets compassion, where science serves humanity. The work that will happen here will not be confined to the walls of academia –  it has the potential to ripple outward into clinics, into hospitals, and into homes. It will shape guidelines, inform policy, and ultimately, improve outcomes for patients across our province and beyond.”

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.”
