Filter by:Preterm infants undergo early separation from parents and are exposed to frequent painful clinical procedures, with resultant short- and long-term effects on their neurodevelopment. We aimed to establish whether the mother's voice could provide an effective and safe analgesia for preterm infants and whether endogenous oxytocin (OXT) could be linked to pain modulation. Twenty preterm infants were exposed to three conditions-mother's live voice (speaking or singing) and standard care-in random order during a painful procedure. OXT levels (pg/mL) in saliva and plasma cortisol levels were quantified, and the Premature Infant Pain Profile (PIPP) was blindly coded by trained psychologists.
This study is conducted to assess the role of pregnant women's daily mobility living in the Eurometropole of Strasbourg in a context of the existence of environmental exposure disparities (PM10, PM2.5, NO2). Furthermore, this study will tend to identify the critical windows of exposure and of greater risk of the adverse pregnancy outcomes as low birth weight and prematurity. A second question addressed in this work is to assess the relationship between the pregnant women's socio-economic status and the air pollution exposure (PM10, PM2.5, NO2).taking into account the spatio-temporal variations of the exposure as well as the critical windows of exposure during pregnancy. The present work deals with the following question "how does the combination of environmental exposure, socio-economic status and women's daily mobility, could contribute to socio-spatial inequalities in the health of the newborn? The underlying hypothesis is that the accumulation, in given area, of environmental exposures (as PM10, PM2.5 and NO2), of unfavorable living conditions (socio-economic environment) and individual factors (specific spatio-temporal trajectory) would induce an increased risk for the health of the newborn, (more particularly in terms of birth weight and term of birth). This hypothesis is structured 4 sub-hypotheses: i) The misclassification of exposure is socially distributed among pregnant women living in the Eurometropole of Strasbourg. ii) Beyond maternal and fetal characteristics, pregnant women who reside in a more socio-economically deprived neighborhood and / or with higher levels of environmental exposure to PM10, PM2.5 and NO2 are more at risk of preterm newborn and low birth weight newborn. iii) The accumulation of environmental exposures of the pregnant women and their daily mobility over their territory during the pregnancy increase the health inequalities of the newborn. iv) The critical windows of fetal exposure to pollutants is related to the socioeconomic level of their neighborhood and to the daily mobility of the women in their territory during pregnancy. Women are included in the study at the time of their first or second trimester ultrasound. Here are the tools used in the study: Descriptive survey of their idividuals characteristics, descriptive survey of women's mobility to assess their exposure during each trimester of pregnancy.
Pregnant women are a vulnerable and high-risk population, as COVID-19 is associated with an increased risk preterm birth, cesarean section, and maternal critical care. This study will examine the factors that impede testing for SARS-CoV-2 (the causative virus among pregnant women), help determine optimal testing strategies by evaluating the necessity of testing for asymptomatic disease in pregnancy, inform prenatal care plans by assessing the full impact of infection, and contribute to a provider's ability to counsel women and create prenatal care plans if they are pregnant or considering pregnancy.
The investigators will test a new medical grade swaddling system for optimal and more appropriate positioning for preterm infants. This is a trial focused on sleep state, state regulation and long-term neurodevelopment. The central hypothesis is that this novel swaddling method will promote sleep and an optimal sleep-wake cycle, while also improving the neurodevelopment of preterm infants. It is proposed that adequate positioning and secondary feedback of natural movement of arms and legs stimulates and fosters normal brain development.
Globally, preterm birth (15 mill. per year) is the leading cause of under-5 child mortality (1 mill. per year) and morbidity. Important pathways include preterm labor contractions, Preterm Prelabor Rupture of the Fetal Membranes (PPROM), and iatrogenic delivery. At labor, the fetal amniochorionic membrane undergoes a cellular senescence and shed fetal amniochorionic membrane cells (ACM cells) to the maternal circulation. In collaboration with the private firm ARCEDI Biotech and The University of Texas Medical Branch at Galveston, Aarhus University has identified specific antibodies, which can be used to isolate ACM cells from maternal blood. Thus, the aim of this study is 1) to characterize ACM cells by histological and immunological techniques, and 2) in a cohort assess their performance as biomarkers of amniochorionic membrane dysfunction, including early detection of threatening preterm birth. In perspective, the findings are expected to improve the diagnostics and treatment of preterm birth.
This study investigated the effect of facilitated tucking in the early postpartum period on preterm neonate comfort and breastfeeding performance.
COVID-19, the coronavirus responsible for the pandemic that began at the end of 2019 in China, spreads through respiratory droplets and direct contact. The most common symptoms of the disease include fever, cough, asthenia or myalgia, wheezing and headache, and the most serious complication is acute respiratory distress syndrome (ARDS). The new coronavirus has continued to spread to multiple countries and continents so much so that the epidemic was declared a Public Health Emergency of International Interest (PHEIC) by the World Health Organization (WHO) on January 30, 2020. In the first phase of emergency worldwide, characterized by high morbidity and mortality, scientific interest has been mainly directed to the study of the transmission mechanisms of the infection, diagnostic tools and therapies for ARDS, especially in elderly and co-morbid patients. Interest has rapidly spread to other categories of patients and in particular to pregnancy, on which the virus could impact in different ways, with consequences for both the mother and the fetus. A recent systematic review that included all published reports on Coronaviruses (COVID-19, SARS, and MERS) in pregnancy showed that preterm delivery is the most frequently reported adverse event in these women, and that COVID-19 is associated with an increased risk of preeclampsia and caesarean section. Nonetheless, the limited sample size, the main inclusion of cases reported for acute respiratory symptoms, the lack of information on previous pathologies potentially capable of complicating pregnancy, do not allow for the extrapolation of strong evidence on the course of infection in pregnancy. Therefore, the current status of the scientific literature does not allow for general and wide-ranging implications. THe investigators therefore believe it is particularly useful to investigate maternal and fetal outcomes in this new broader scenario, including all pregnancies associated with asymptomatic or symptomatic SARS-CoV-2 infection, found in any gestational period, in order to evaluate in a "real world scenario" "Actual rates of maternal-fetal and neonatal adverse events
Pregnant women with short cervical length (<25 mm) in second-trimester ultrasonographic assessment are at high risk for preterm birth, a major cause of perinatal mortality and morbidity worldwide. Some of these short-cervix women proceed to a more advanced stage manifested as a painless prematurely dilated cervix in the second trimester. It is not fully understood why some women have short cervical length or prematurely dilated cervix (cervical insufficiency), although evidence is mounting that there is an association between short cervical length and infection by microorganisms. The investigators hypothesize that the cervical microorganisms in pregnant women with a shortened or dilated cervix are different, compared with those in women with normal cervical length and a closed cervix.
Oxygen treatment is common in babies born early (preterm) and requiring intensive care. Having too much or too little oxygen can increase the risk of damage to the eyes and lungs, and contribute to death or disability. Preterm infants because of their immaturity experience episodes of low oxygen levels. The low oxygen episodes are primarily due to pauses in their breathing (Apnoea of prematurity) and immaturity of their lung. These episodes persist for weeks to months. The lower the gestation at birth the longer the duration of these events. Studies have shown that these episodes of low oxygen saturations especially if frequent and prolonged is associated with poor developmental outcome, severe eye disease and lung disease. Traditionally, the oxygen delivery is manually adjusted when infant has low oxygen saturation. However previous studies have shown despite the best efforts the oxygen level can only be maintained less than half of the time and nearly a one-fifth of the time infant spends in low oxygen levels and nearly one-third of the time in high oxygen levels. With advancement in the neonatal care, preterm infants tend to spend more time on non invasive respiratory support. Now it is possible to maintain oxygen level in target range by using automatic control of oxygen delivery on non invasive support. With the proposed study, we would like to study the efficacy of automatic control of oxygen delivery in reducing the time spent in very low and high oxygen levels when infants are on non invasive respiratory support namely High Flow Nasal Cannula support.
Preterm births are defined as delivery prior to 37 weeks gestation and account for 35% of infant deaths in the first year of life. Early preterm birth are deliveries prior to 32 weeks gestation and account for more than 70% of neonatal deaths and 36.1% of overall infant mortality. Women who have delivered a preterm infant and who have a short pregnancy interval (time between giving birth and subsequent conception) have an increased risk of preterm birth in subsequent pregnancies. The investigators hope to understand if a mobile health strategy can be used to reduce spontaneous preterm births via improved patient engagement, care coordination, and adherence to recommended care vs a traditional paper-based health strategy.
