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.”

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
