Dr Nomakhuwa Tabane is the Head of the Department of Paediatrics and Child Health at the University of the Free State.

The first 1 000 days of a baby’s life, from conception to the age of two, constitute a critical period during which children’s brains form as many as 1 000 neural connections every second – a pace that will not be repeated in their lifetime.

These connections are the building blocks of every child’s future, which makes the role of a campaign like the First 1 000 Days vitally important. It highlights the importance of stimulation and learning from the earliest possible moments, good nutrition for expectant mothers, prevention of malnutrition of children, and early diagnosis of chronic, life-threatening illnesses and developmental disorders.

This is according to Dr Nomakhuwa Tabane, Head of the Department of Paediatrics and Child Health at the University of the Free State (UFS). The campaign was promoted by Dr Tabane’s department in partnership with the Mother and Child Academic Hospital (MACAH) Foundation.  The annual campaign kicks off on 1 November each year.

“There are certain factors that can interfere with this process and result in irreversible damage to children’s brain development, poor growth, and compromised immunity. Those conditions include prematurity, ischaemic brain damage, and infections. These are also the top contributors to the neonatal mortality.

“In the one-month to 49-month-old period, the causes of mortality and morbidity that affect brain development and growth include respiratory illnesses like pneumonia, diarrhoeal diseases, and malnutrition,” says Dr Tabane. 

Aims of the campaign

The First 1 000 Days initiative promotes excellent mother, infant, and child healthcare by supporting community-based programmes that drive the message of the importance of the first 1 000 days of life to teenagers, young adults, healthcare workers, and the public. This initiative aims to bring about interventions that can address the Under-5 Mortality Rates (U5MR), including Neonatal Mortality Rates (NMR), Infant Mortality Rates (IMR), and Perinatal Mortality Rates (PMR).

“The campaign also aims to improve the growth and development of children in their first 1 000 days of life from conception until they are two years old. It also aims to improve expectant mothers’ health and prevent and decrease maternal mortality in the Free State, as well as to prevent unwanted pregnancies, focusing on decreasing teenage pregnancies.”

According to Dr Tabane, the 2020 South African UN Inter-agency Group for Child Mortality Estimation (UNIGME) estimate for U5MR was 32 deaths per 1 000 live births, NMR of 11 per 1 000 live births, and infant mortality rate (IMR) of 26 per 1 000 live births as compared to the Medical Research Council (MRC) estimate of U5MR of 28 per 1 000 live births, NMR of 12 per 1 000 live births and IMR of 21 per 1 000 live births (15).

South Africa behind other BRICS countries

Based on the 2020 UNIGME report, says Dr Tabane, South Africa has achieved the Sustainable Development Goals (SDG) goals of NMR and the U5MR. South Africa’s indicators were much better than the UNIGME and the MRC 2020 estimates, but it still falls behind other BRICS countries.

“In contrast to other BRICS countries (Brazil, Russia, India, China, and South Africa), UNIGME reports that in the same reporting period of 2020, China’s U5MR was seven per 1 000 live births, Brazil's 15 per 1 000 live births, and Russia's five per 1 000 live births (16). In 2020, the South African national in-hospital neonatal mortality rate (NMR) based on DHIS data was 12,0 per 1 000 live births; the infant mortality rate (IMR) was 15.1 per 1 000 live births, and the under-5 mortality (U5 MR) rate was 16.9 per 1 000 live births, with differences amongst provinces,” says Dr Tabane.

The first 1 000 days campaign’s interventions include education to prevent illnesses and deaths and promote good health, growth, and development. While many training programmes on child survival strategies have been rolled out (e.g., MSSN, HBB, ETAT, AANC, ESMOE, and IMCI), in-service training still has significant gaps.

Other interventions include preventing unwanted and unplanned pregnancies, providing healthcare support for therapeutic and interventional care, strengthening the implementation of the existing strategies developed by the Department of Health to reduce Maternal and Child Mortalities, and monitoring and evaluating the interventions.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
