Active clinical trials for "Premature Birth"

100 women divided into 3 groups: Group I: included 50 women with preterm premature rupture of membranes (PPROM, n=50) with gestational age from 24 to 34 weeks. Group II: included 25 term non-labor control (T-CTR, n=25) with gestational age from 37 to 41 weeks. Group III: included 25 preterm non-labor control (P-CTR, n=25) with gestational age from 24 to 34 weeks.The myometrial thickness at 4 different sites9: a) The lower uterine segment (LUS): 2cm above the reflection of the full urinary bladder (b)The anterior wall: 1cm above the maternal umbilicus. (c)Fundus: by placing the scan probe perpendicularly above the uterine fundus so that the entire curvature of the uterus was visualized. (d)The posterior wall: through using the maternal abdominal aortic pulsation as an anatomic marker. At least 3 measurements were obtained at each site and averaged. The latency interval is determined in each of the 3 groups.

The Environmental Factors and Embryonic Development Project was set up to investigate environmental exposures and behavioral factors responsible for embryonic dysplasia and gestational complications in pregnant women.

The primary objective of the study is to assess the incidence and severity of the periodontal infection of patients with preterm labor. The secondary objective of the study is to analyze the relationship between preterm labor and periodontal infection, using clinical, biochemical and microbiological methods.

Noninvasive respiratory supports (NRS), such as continuous positive airway pressure (CPAP), noninvasive ventilation, high flow nasal cannula (HFNC) or nasal oxygen (O2), are commonly used in preterm newborns hospitalized in neonatal intensive care unit. However, given the lack of validated criteria, clinicians usually choose the NRS according to clinical parameters and patients' comfort. Several studies have demonstrated the interest of the measurement of the work of breathing (WOB) to optimize the settings of NRS in children, but no study has already demonstrated the utility of WOB to optimize the settings of NRS in preterm infants. Therefore, the aim of this study is to measure the WOB during the utilisation of three different NRS (CPAP, HFNC, O2), in order to optimize the choice of the type and settings of NRS in a randomized group of 30 newborns born prematurely before 30 gestational weeks and still requiring NRS at 29 post conceptual weeks. Moreover, the investigators will compare in the newborns with the optimized NRS by WOB vs. a standard care control group (NRS type and settings determined as clinical routine): 1) the respiratory morbidity and mortality one month after the initial assessment, and at the time of hospital discharge (or transfer) or at 36 weeks of age corrected (whatever comes first), 2) the weaning time of the NRS, 3) the incidence and severity of broncho-pulmonary dysplasia (BPD) at 36 weeks of age corrected. Indeed, incidence of BPD is still around 40% in premature infants born before 28 gestational weeks. The hypothesis of the investigators' study is that the optimization of the type and settings of the NRS could reduce the weaning delay and contribute to reduce the incidence and severity of BPD in premature newborns.

Recent research has identified differences in the quality of mother-child interaction and gene expression of six key molecules involved in stress response and neurobehavioral development in preterm infants (born <32 weeks of gestational age) with early skin to skin contact after birth compared to infants with visual contact at six months corrected age. We hypothesize that these differences are still identifiable at the age of 6 to 8 years and that quality of bonding in preterm infants born <32 weeks of gestation differs significantly from late preterm infants and full-term infants.

The purpose of this protocol is to study the consequences of prematurity on the optic nerve. Indeed, the work already carried out on the subject suggests that prematurity induces suffering of the optic nerve with a loss of optical fibre, an essential element in the transmission of the visual nerve signal to the brain. The investigators will therefore study two populations: a population of premature infants aged 5 to 10 years, and a control population of term infants. The examinations performed are painless, non-invasive and non-irradiating. To date, there are no known adverse reactions to these tests. These examinations are a photo of the fundus (retinophotography), a pachymetry (measurement of the thickness of the non-contact cornea), an OCT RNFL (optical coherence tomography, scanner of the non-irradiating non-painful optical nerve) and the taking of the IOP (intraocular pressure). They aim to measure the main morphological characteristics of the eye and the optic nerve. This is a prospective observational study. The inclusion and measurements necessary for the study are made on the day of the consultation. The expected results will provide new data on this population of premature infants, allowing for better management if a pathology involving the optic nerve were to occur at any age in these patients.

We will compeer fecal microbiome in preterm birth with fecal microbiome of team labor

Sonographically, cervical length measurement is widely used in obstetrics. Studies have revealed that early detection of short cervix can be a predictor of predicting preterm labor. Transvaginal ultrasonography has been shown as a reference method for the recognition of the short cervix, as well as it may be useful in the transabdominal evaluation in the studies conducted. In addition to the advantages of transvaginal evaluation, it is time consuming and disadvantages of some women during anxiety and discomfort during this procedure. Transabdominal ultrasonography, which provides a non-invasive evaluation, is more preferred by some patients than transvaginal. The aim of this study is to investigate the value of the cervical length measured by transabdominal route, which is a more acceptable method for pregnant women, in predicting preterm birth.

The fatty acid composition in blood and subcutaneous adipose tissue of infants that have an clinical indicated operation is studied.

The family-centered care is based on dignity and respect, information sharing, collaboration and participation in care and decision-making. In a neonatal unit, the medical round by the attending physician is an important moment for shairing information with the medical and nursing staff and for the decision making process. In France, parents are rarely actively involved in the medical round. The aim of this study is to plan the implantation of the Family-centered round in a neonatal department using the 6 steps of the "Intervention mapping": 1/needs assessment; 2/ performance and change objectives; 3/ theory-based framework; Curriculum development; 5- adoption and implementation; 6- evaluation and dissemination
