Filter by:Autonomic nervous system (ANS) is an essential regulator for the homeostasis, circulatory and respiratory systems. Heart rate variability, under the dependence of the parasympathetic and orthosympathetic arms is a peripheral witness of its well functioning. Activity ANS indices are technically measurable from the birth by non invasive cardiac monitoring: in given environmental conditions. According to the individualized care given to the baby, we can easily observe by frequential analysis, modifications of ANS level activity; If for a full-term newborn, the balance of ANS allows him to adapt its cardiac frequency to its internal and external environment (thermoregulation, baroreflex, sinus arrhythmia, awakening state) , the premature birth is at the origin of a prolonged defect of global ANS maturation, probably induced by external environmental and stress factors (pain, stimulations, aggressive noise and lights). This disrupted maturation profile in case of prematurity, was confirmed in two preliminary studies on premature babies reaching term for gestational age. We hypothesis that adapted sensorimotor care could decrease this stress and optimize the ANS activity profile. In a prospective study, by a non invasive real-time measure, we analyse impact of stress on ANS activity in a premature population, hospitalized in our neonatal intensive care units.
Previous studies have suggested that premature luteinization (PL)during controlled ovarian stimulation (COS) decreases the implantation rate due to a negative effect on the endometrium receptivity. This study aims to describe the impact on endometrial gene expression of PL in GnRH antagonist and GnRH agonist cycles.
The machines and oxygen used to help very premature babies breathe can have side-effects, such as bronchopulmonary dysplasia (BPD). Infants with BPD get more complications (a higher death rate, a longer time in intensive care and on assisted ventilation, more hospital readmissions in the first year of life, and more learning problems) than infants who do not develop BPD. Doctors try to remove the tube in the wind-pipe that links the baby to the breathing machine as soon as possible. However, small babies get tired, and still require help to breathe. One of the standard and common techniques to help them breathe without a tube in the wind-pipe is to use simple pressure support, nasal continuous positive airway pressure or nCPAP. This supports breathing a little, but it is often not enough to prevent the need to go back on the breathing machine. Nasal intermittent positive pressure ventilation (NIPPV) is similar to nCPAP, but also gives some breaths, or extra support, to babies through a small tube in the nose. NIPPV is safe and effective, and already in use as an alternate "standard" therapy. The main research question: After being weaned from the breathing machine, is NIPPV better than nCPAP in preventing BPD in premature babies weighing 999 grams or less at birth?
The aim of our study is to evaluate the effect of use of prophylactic vaginal progesterone on the incidence of severe preterm delivery, defined as delivery before 33+6 weeks in women with a short cervical length of 15mm.
The purpose of this study is to evaluate the growth of the lung and how easily gas can be taken up by the lung in healthy infants born at full term without any breathing problems and infants born prematurely.

Kangaroo holding is a skin-to-skin method of holding a baby. Many research studies have investigated the maternal and infant benefits associated with kangaroo holding. The purpose of this study is to determine if kangaroo holding a baby changes the amount and composition of breast milk pumped before and after the kangaroo holding session. Hypotheses: 1. There is a significant difference in volume of maternal breast milk pumped after kangaroo holding premature infants as compared to maternal breast milk pumped after non-holding conditions 2. There is a significant difference in the composition of maternal breast milk pumped after kangaroo holding premature infants as compared to maternal breast milk pumped after non-holding condition.
Vitamin A is important for the development of healthy eyes and lungs. Very low birth weight premature babies have low body stores of vitamin A and are prone to diseases of the eye and lungs. Previous work has shown that intramuscular (IM) vitamin A reduces the number of babies who require prolonged oxygen therapy, and may also reduce the number of babies affected by retinopathy of prematurity (ROP)). There is also some evidence that the conjunctiva shows signs of deficiency of vitamin A in premature infants, particularly those who develop ROP. Our own work here in Glasgow suggests that, compared to babies born at full term, premature babies' eyes are less sensitive to light and we believe that this may reflect shortage of vitamin A in the eye. This study will examine the effects upon the eye of giving extra intramuscular vitamin A to very low birth weight, premature infants. We will also measure blood levels of vitamin A and calculate liver stores of this nutrient.
Pre-Term Labor (prior to 37 weeks gestation) is the largest single cause of infant morbidity and mortality and is frequently associated with long-term disability. Oxytocin is a hormone produced by the body during labor. GSK221149A is an experimental drug that will be used to block the effects of oxytocin, and therefore pause or prevent contractions. In this study, patients with preterm labor will be given an intravenous infusion of GSK221149A over approximately 12 hours followed by an oral tablet in Parts A and B. In part C of this study, patients with preterm labor will be give an intravenous infusion of GSK221149A over approximately 48 hours. The use of a rescue tocolytic is allowed in the study.
The aim of the study is to determine if N-acetylcysteine (a potent free radical scavenger) prevents the occurrence of adverse neonatal outcomes in preterm deliveries complicated by infection associated with preterm labor or preterm premature rupture of membranes (PPROM). The working hypothesis is that in pregnancies complicated by intra-amniotic infection or inflammation, N-acetylcysteine protects the fetus by preventing the development, or decreasing the intensity and/or progression of the fetal inflammatory syndrome.
