Filter by:Retinal vascularization in humans develops between the 16th and 36th week of amenorrhea, centrifugally from the papilla. In case of premature birth, the immature retinal periphery is at risk of ischemic damage due to lack of vascular development. Prematurity is often associated with respiratory fragility. It often requires ventilatory assistance in the form of oxygen therapy, invasive (oro-tracheal intubation) or non-invasive, which leads to reflex arteriolar vasoconstriction aggravating the ischemia already present. One may wonder if there are subclinical retinal vascular changes, detectable on Tomographie par Cohérence Optique-Angiography (, that could explain the greater risk of amblyopia and optical correction observed. Tomographie par Cohérence Optique-Angiography is a fast growing technique in retinal vascular pathologies: it is a simple, fast, reliable, non-invasive, injection-free examination, which allows to study in high resolution the retinal vascularization, with a distinct analysis of the retinal plexuses and the choriocapillaris
This is a study proposal for a clinical trial to evaluate the effectiveness of a reduced dose of antenatal betamethasone (a steroid medication) in preventing respiratory problems in late preterm infants (born between 34 and 36 weeks of gestation). The study will be conducted in medical centers in Israel and will involve women who are at high risk for delivering a late preterm infant. The participants will be randomly assigned to receive either a full dose (12 mg) or a quarter dose (3 mg) of betamethasone, administered 24 hours apart. The main outcome measure of the study will be the incidence of respiratory problems or neonatal death within 72 hours of delivery in the two groups. The study is designed to determine if the reduced dose of betamethasone is non-inferior (i.e., not significantly worse) than the full dose in preventing respiratory problems in late preterm infants.
The purpose of the CHAPTER study is to help understand how complications during pregnancy, such as preterm birth, affect how childrens' hearts and blood vessels develop.
The aim of the study is to investigate levels of brain perfusion and elasticity in preterm neonates when they reach the estimated due date and to compare the data with magnetic resonance imaging at term. Contrast enhanced ultrasound (sulphur hexafluoride) and ultrasound-assisted elastography will be used to evaluate the state of brain perfusion with ultrasound. Different appropriate imaging sequences will be used regarding MRI, including asl-perfusion. Neonates recruited from the Neonatal Intensive Care Unit (NICU) of Turku University Hospital will be recruited.
The aim of this study is to investigate if tocolysis with atosiban in late preterm birth (30 to 34 weeks) is (cost-) effective compared with placebo in improving neonatal morbidity and mortality.
Preterm birth is associated with maternal increased risk of cardiovascular disease later in life. In an observational case- control study, investigators want to evaluate whether women with preterm birth have increased levels of biomarkers for cardiovascular disease, to reveal potential pathophysiological mechanisms in common.
This observational study aims to test the level of parathyroid hormone in pregnant women. The main question it aims to answer is: n Pregnant women, are the levels of serum PTH, calcium, magnesium, phosphorus & albumin similar in both preterm and term births?
The purpose of this study is to confirm hypothesis that Glibenclamide can be administered orally and is an alternative to insulin therapy in treating transient hyperglycemia of premature newborns.
To define the characteristics of hemodynamically significant PDA by echocardiography, to investigate the systemic effects of the ductus with cerebral and renal Doppler flow studies, and to determine the oxygen consumption in the cerebral tissue with NIRS in newborns below 32 weeks of age with PDA.
The goal of this superiority crossover randomised controlled trial is to investigate whether there is an optimal position at which to perform kangaroo mother care (KMC) in extremely preterm infants in the NICU. The main question it aims to answer is: 1) is there an optimal position for an infant to be held during KMC and 2) to optimise benefits for infants receiving KMC. Participants will be: 1) randomised into two groups which determine which angle they will start at first, 2) assessed over two hour-long sessions on different days with a change in the angle at the 30 minute point, 3) monitored using a Massimo NIRS machine which will record oxygen saturations, cerebral NIRS values and heart rates, and 4) monitored for any episodes of desaturations and bradycardias during this time. Participants will then be assessed beginning with the the other angle first on a different day. The researchers will then compare the two groups to see if being held at a 30 degrees during KMC is superior to being held at 60 degrees in terms of physiological stability.
