Hypothesis
We speculate that a deficiency of thyroxine results in impaired neurological pathways during early neurogenesis which results in abnormalities in myelination and alters the cytoarchitecture of specific brain structures such as the hippocampus, caudate nucleus and thalamic nuclei.
Conclusion
The study aims to determine if thyroxine supplementation affects brain development in extremely preterm infants.
Supporting Evidence
- Infants born at extreme prematurity are at high risk of developmental disability.
- Low thyroid hormone levels in preterm infants are associated with poor neurodevelopmental outcomes.
- Thyroid hormones are essential for normal brain development and myelination.
Takeaway
This study is trying to find out if giving a hormone called thyroxine to very premature babies helps their brains grow better.
Methodology
A multi-centred double blinded randomised controlled trial of thyroid hormone supplementation in babies born below 28 weeks' gestation.
Potential Biases
Potential biases may arise from the double-blind design and the selection of participants.
Limitations
The sample size for the subgroup analysis was small, which may limit the reliability of the findings.
Participant Demographics
Infants born below 28 weeks' gestation.
