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.”

Research helps farmers save with irrigation

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
