Optimising Non-invasive Ventilation At Birth For Preterm Infants

Summary
Infants born very premature require respiratory support at birth to make the transition to newborn life. As these infants are very immature and prone to injury, modern respiratory care strategies utilise the least invasive approaches mainly applied using a facemask. However, we have discovered that the larynx is closed at birth and thereby prevents air from entering the lung. This application is focussed on optimising the efficiency of facemask ventilation at birth and stimulating breathing.
An Integrated Approach To Inotropic Support In Preterm Neonates

Summary
Poor cardiovascular function in preterm babies can lead to inadequate blood flow to the brain and brain injury. Current treatments to improve heart function are often ineffective. This study will examine the effects of treatment on different parts of the cardiovascular system, and how these effects interact. It will identify reasons for the lack of effectiveness and provide insight which will help to design better treatments for preterm babies.
Injury to the developing brain, whether sustained during pregnancy or at birth, is the underlying cause of many cognitive and motor disabilities, including cerebral palsy. This project will identify the cellular pathways that cause developmental brain injury in preterm and term infants, and then administer umbilical cord blood stem cells at different timepoints to assess their efficacy at reducing brain injury. This project will inform treatment with cord blood stem cells in high risk infants.

Summary
Cerebral palsy (CP) is the most common cause of physical disability in children and it is well recognised that the brain injury that underlies CP occurs during pregnancy or around the time of birth. Stem cells isolated from umbilical cord blood offer a promising new therapy for children with CP. This proposal will explore the mechanism of how cord blood stem cells can reduce brain inflammation and damage caused by hypoxia-ischemia, an event known to lead to cerebral palsy.
Contribution Of Disturbed Blood Flow And Cerebral Metabolism To White Matter Damage In The Perinatal Brain

Summary
It has been known for some time that the white matter regions of the developing brain are particularly vulnerable to damage. These regions are deep in the brain near the ventricles, and are rich in myelin sheaths wrapped around the nerve fibres running from cell-rich areas in the outer layers of the brain to other regions, and down into the spinal cord. Damage to white matter usually leads to behavioural, learning and motor problems in the newborn infant - in its severest form, seen as cerebral ....It has been known for some time that the white matter regions of the developing brain are particularly vulnerable to damage. These regions are deep in the brain near the ventricles, and are rich in myelin sheaths wrapped around the nerve fibres running from cell-rich areas in the outer layers of the brain to other regions, and down into the spinal cord. Damage to white matter usually leads to behavioural, learning and motor problems in the newborn infant - in its severest form, seen as cerebral palsy. Such outcomes are often associated with the presence of asphyxia and infection during pregnancy, leading to the belief that the damage first arises while the baby is still in utero. In this application we suggest that asphyxia and-or infection during pregnancy cause prolonged disturbances in the regulation of blood flow and integrity of the blood-brain barrier in the developing brain, together with changes in metabolism that result in accumulation of prostaglandins and the toxic hydroxyl radical, leading irreversibly to cell death. If this series of events proves to be true, we have suggested and will test several protocols for protecting the fetal brain, which should be readily translatable to clinical practice.Read moreRead less
