Active clinical trials for "Premature Birth"

Preterm infants (PT) often need to spend their first weeks of life in the Neonatal Intensive Care Unit (NICU) where they are exposed to several adverse conditions. Whereas a consistent number of studies suggest that NICU-related experiences may have effects on infant development including long-term impairments in emotional regulation, the underlying mechanisms remain partially unexplored. Spectral analysis of EEG signal has demonstrated that frontal alpha-band asymmetry represents a reliable biomarker of social-emotional functioning. In the literature, higher right frontal activation has been associated with worse emotional regulation but no study has measured this value during a condition of social-emotional stress such as the Still Face paradigm. Our hypothesis is that higher alpha activity will be recorded in right frontal areas in premature infants compared to healthy controls and that this activation will be associated with higher negative emotionality (i.e., worse socio-emotional regulation) expressed during the Still Face paradigm. Moreover, despite several changes in epigenetic patterns have already been reported in association with prematurity and early adverse experiences, the relationship between epigenetic changes and electroencephalographic patterns (i.e. frontal alpha asymmetry) remains unexplored. The investigators therefore expect to find associations between increased methylation levels of socio-emotional and stress related genes (i.e. SLC6A4, NR3C1, OXTR, Piezo1, Piezo2, TRPV1 and TRPM8) with spontaneous oscillations of neural activity at frontal sites measured by EEG (i.e. frontal alpha asymmetry). Finally, there is ample evidence that infant's socio-emotional regulation abilities are highly dependent on the behaviors of their caregivers. More recent studies have shown that behavior can be influenced by interoceptive awareness, i.e., the ability to perceive the physiological condition of one's body in this way and to represent one's internal states. Better interoceptive awareness is associated with better recognition of others' needs, more empathetic behaviors, and better emotional regulation. Therefore, with the present exploratory study, the investigators will compare the interceptive awareness of mothers of preterm infants with that of mothers of full-term infants by exploring possible associations of this dimension with the socio-emotional responses of preterm infants and healthy controls. The investigators expect that better socio-emotional regulation of infants is predicted by a higher level of interoceptive awareness in mothers, regardless of prematurity condition.

The aim of this study is to try and find links between the microscopic organisms (such as bacteria, yeasts and viruses) in the vagina, and twin pregnancies that deliver too early (preterm birth). Being born earlier than expected (preterm birth) happens in over half of twin pregnancies with 1 in 10 sets of twins delivering before 32 weeks gestation. Sometimes, when birth happens very early, babies can be at risk of serious harm including damage to the brain, lungs and bowel - all of which can result in life changing disabilities. How severe these problems are is related to how early they are born. Unfortunately, tests used to find women at risk of preterm birth have only been proven to work when the woman is carrying one baby, not twins, and at present no treatment has been shown to be effective in stopping a twin pregnancy from delivering early. Preventing twins from being born too early is therefore a target for research by the NHS and patient groups including the James Lind Alliance. It is normal for every woman to have microscopic organisms (such as bacteria, yeasts and viruses) in the vagina. New interest has been shown at looking closely at these organisms during pregnancy. These organisms can change and may be related to the number of weeks a woman will go into labour, however to date all research on this has been conducted in pregnancies with only one baby. We want to explore these organisms in twin pregnancies; taking swabs from the vagina at 16- and 28-weeks of your pregnancy, along with at the time of birth. Information will be gathered on the organisms present in the vagina (both of women that deliver too early and those that deliver on time), hoping this information will help us understand why preterm birth happens and help predict the chances of preterm labour in twin pregnancies. By identifying specific organisms linked with preterm birth, we also hope to be able to guide new targets for treatments to prevent preterm birth in twins in future. Due to the small number of twin pregnancies, measurements of how 'stiff' the neck of the womb (cervix) are along with blood samples will be taken. Research has shown that there may be links with how stiff the neck of the womb is and premature birth as well as markers within the blood that may help us predict preterm birth that are yet to be discovered. This will provide the foundations for a future research study.

Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone secreted by the pineal gland with several important functions, including regulation of the circadian rhythms, and antioxidant and anti-inflammatory effects, accumulating evidence revealed that it also plays an important role in pain modulation through multiple mechanisms. The investigators aimed to evaluate the analgesic effect of melatonin during venous cannula insertion in preterm neonates by assessing Premature Infant pain Profile score (PIPP) before and 5 minutes after the procedure, and to demonstrate the significant relationship between procedural pain and Malondialdehyde (MDA), a well-accepted marker of oxidative stress through measuring MDA after 60 minutes of the procedure.

The goal of this observational study is to learn about the feasibility of hemodynamic measurement by the UltraSonic Cardiac Output Monitor (USCOM) in very preterm or very-low-birth-weight infants. The main questions it aims to answer are: 1) establishing reference ranges for USCOM parameters in this specific population, 2) assessing the effect of patients' characteristics and other possible confounders on USCOM parameters, and 3) evaluating the short-term repeatability of the measurement. Participants will receive USCOM measurements on 3, 7, and 14 postnatal days.

The aim of the DenBalo study is to apply integrated multi-omics methods to examine the biological mechanisms underlying this vulnerability in preterm neonates 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: To describe and compare gut microbiota, immune system and breastmilk components in pre- versus full-term neonates in urban Burkina Faso. To describe and compare the development of the gut microbiota, the immune system and breastmilk components during the first six months of life in pre- versus full-term infants in urban Burkina Faso. 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 pre- versus full-term infants in urban Burkina Faso.

This is an observational study to collect data from Japanese babies with retinopathy of prematurity (ROP) who will be treated with Eylea. In observational studies, only observations are made without specified advice or interventions. ROP is a condition that affects the eye and occurs only in babies who are born too early. Most cases of ROP are mild and get better without treatment, but more serious cases need to be treated in time. ROP happens when the blood vessels in the "retina" grow abnormally. The retina is the layer of tissue at the back of the eye that picks up light and sends messages to the brain. In babies with ROP, these abnormal blood vessels can leak. This causes damage to the retina and can sometimes move it out of place causing medical problems such as blindness. Eylea is received as an injection into the eye. It works by blocking a certain protein (VEGF) that can cause blood vessels in the retina to grow abnormally. Eylea is already available in Japan and is approved for doctors to prescribe to babies with ROP. The participants in this study are Japanese babies with ROP that their doctors decided to treat with Eylea before the start of this study. Babies with ROP that were already prescribed Eylea by their doctors may also be included. The main purpose of this study is to collect more data on how safe the treatment with Eylea is in babies with ROP under a real-world setting. Another purpose of this study is to collect more data on how well Eylea works in these participants. To see how safe Eylea is, the study doctors will collect all medical problems that the participants treated with Eylea have. These medical problems are called adverse events. Doctors keep track of all the adverse events that happen, even if they do not think that they might be related to the treatment. To see how well Eylea works, the study doctors will check the number of participants: with no active ROP after starting treatment where ROP came back up to 6 months after start of treatment In this study, the study doctor will: collect past data of the participants from medical records interview the participants collect treatment-related data during routine visits. The study duration is 6 months with 3 planned visits. One visit will be at start of treatment, one at one month and one at 6 months after start of treatment. All data required for this study will be collected during routine visits. Besides this data collection, no further tests or examinations are planned in this study.

The goal of this clinical study is to test a new, novel medical device designed to improve speech sound differentiation among hospitalized preterm infants. The device is designed to be used at an age equivalent to 32 weeks of gestation or older and to integrate readily into clinical practice for use by nurses and therapists staffing Level II to Level IV NICUs. Preterm born infants are at high risk for neurosensory impairments and developmental delays. In the NICU, infants are often deprived of infant-directed parental speech because of numerous challenges to parental visitation, resulting in reduced differentiation of speech sounds, altered brain structure and poor language outcomes. The study will explore the effectiveness of a novel medical device designed for infant learning through contingent sucking on a pacifier equipped with a sensor for suck pressure/timing, connected to a speaker that delivers mother's voice. The study will test the hypothesis that there will be a greater response difference between speech sounds on EEG, for infants receiving the suck-contingent mother's voice intervention than for infants hearing the same amount of non-contingent mother's voice from a speaker device.

The purpose of this study is to determine whether increased transferrin saturation in plasma (that reflects iron overload and/or low transferrin) is an independent risk factor for ROP development and severity. Preterm infants born at <31 week's post-menstrual age (PMA) or ≤1250g of birth weight will be included. Iron parameters in plasma will be measured during the first month of life. Retinopathy of prematurity (ROP) will be screened as currently recommended. The relationship between plasma iron parameters and ROP development and/or severity will be established.

Extremely low birth weight (ELBW), birth weight less than or equal to 1000 g, infants are at high risk for developing brain injury in the first week of life. Intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL) are the most common injuries in this group of infants. Their incidence is inversely proportional to gestational age (GA) and birth weight (BW). These lesions are associated with neurodevelopmental delay, poor cognitive performance, visual and hearing impairment, epilepsy, and cerebral palsy; and instability of systemic hemodynamics during transition from intra- to extra-uterine life and during the early neonatal period is believed to be at their genesis. While the incidence of ultrasound- diagnosed cystic PVL has decreased dramatically over the last 2 decades, diffuse PVL detected by magnetic resonance imaging (MRI) is still prevalent in survivors of neonatal intensive care. Moreover, PVL, even when non-cystic, is associated with decreased cortical complexity and brain volume and eventual neurocognitive impairment. Currently, clinicians lack the tools to detect changes in cerebral perfusion prior to irreversible injury. Unfortunately, the incidence of brain injury in ELBW infants has remained relatively stable. Once translated to the bedside, the goal of this research is to develop a monitoring system that will allow researchers to identify infants most at risk for IVH and PVL and in the future, intervention studies will be initiated to use the changes in cerebral perfusion to direct hemodynamic management. The purpose of this study is to first understand the physiology of brain injury and then to eventually impact the outcomes in this high-risk group of infants by assessing the ability of the diastolic closing margin (DCM), a non-invasive estimate of brain perfusion pressure, to predict hemorrhagic and ischemic brain injury in ELBW infants. The information collected for this study will help develop algorithms or monitoring plans that will maintain the appropriate brain perfusion pressure and thereby, prevent severe brain injury.
