Brief Summary
The aim of the DenBalo study is to apply integrated multi-omics methods to examine the biological mechanisms underlying this vulnerability in Small Vulnerable Newborns (SVNs) in LMICs, with the ultimate goal of identifying targeted interventions to reduce morbidity and mortality in this high-risk population. The evidence generated from this project will ultimately help promote healthy pregnancies and the birth of healthy babies. To achieve this goal, three research objectives are proposed:
- 1.To describe and compare gut microbiota, immune system and breastmilk components in SVNs versus healthy community controls in urban Burkina Faso.
- 2.To describe and compare the development of the gut microbiota, the immune system and breastmilk components during the first six months of life in SVNs versus healthy community controls in urban Burkina Faso.
- 3.To investigate the relationship between the composition of the gut microbiota, the immune system and breastmilk components during the first six months of life in SVNs versus healthy community controls in urban Burkina Faso.

All the data collected during the DenBalo study will be pseudonymised (i.e., identifable data can still be linked to patient files by means of a code) and the key to the codes will only be accessible to the principal investigators, or his/her representative. The collected pseudonymised data as well as the collected biological samples can be shared with other (future) researchers for future research projects and studies, exclusively in the context of the same disease/pathology or similar (i.e., in the interest of research on maternal, newborn and child health). This will be done within a strictly legal framework and in compliance with international laws on the protection of personal data. Only anonymized data will be used in any type of documentation, reports or publications (in the medical scientific literature and/or at medical conferences). Personal patient data will be stored for at least 25 years after the end of the study.
