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.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
