Filter by:The purpose of this study is to determine if NT-BNP levels obtained at time of admission for delivery are predictive of intrapartum or postpartum complications in patients with adult congenital heart disease.
Ambulation in pregnancy has been proposed to decrease stress and anxiety, increasing preterm birth. Whether ambulation is causally related to latency is unknown. The FitBit will be used for tracking the number of steps taken daily by each participant, and for encouraging the intervention group to walk. The FitBit is the most widely used physical activity tracker in medical research, and its use has been validated for research use in pregnant women. The purpose of the study is to evaluate whether ambulation in patients with preterm premature rupture of the membranes (PPROM) prolongs latency.
This study will utilize continuous glucose monitoring in women with A2 gestational diabetes. Women will be randomized to continuous glucose monitoring or routine care with fingersticks to check their blood glucose four times daily. It is hypothesized that women in the continuous glucose monitoring arm will have a lower incidence of the composite primary outcome, which includes the following variables: perinatal death, shoulder dystocia, birth weight greater than 4,000 grams, NICU admission for treatment of hypoglycemia (blood glucose level <40mg/dL) and birth trauma, including fracture or nerve palsy.
Thus far no robust data exist as to the effect of repeted course of antenatal corticosteroids in twin pregnancies. The investigators hypothesized that repeat course of betamethasone would further reduce neonatal morbidity in twins born before 34 weeks' gestation when compared with single dose.
Cesarean section (CS) is a major surgical intervention that affects women at childbearing age. Scarring from CS potentially causes discomfort and psychological distress. Emerging evidence indicates that epidermal growth factor (EGF) plays crucial roles in wound healing with the potential of minimizing scar formation. This study aims to investigate the effect of microencapsulated recombinant human EGF (Me-EGF) in scar prevention. Silicone gel was incorporated as part of the routine scar treatment. Healthy women scheduled for cesarean delivery will be enrolled and randomized to three groups: (1) no scar treatment, (2) silicone gel only, or (3) silicone gel plus Me-EGF. Vancouver Scar Scale (VSS) will be used for scar assessment at the 6th month and 9th month after CS.
Pregnancy generates an increased thrombotic risk, and placental-mediated diseases are a risk factor for cardiovascular diseases, in particular: pre-eclampsia (PE), intrauterine growth retardation (IUGR), retroplacental hematomas (HRP), late intrauterine fetal deaths (LIFD) of placental origin and preterm deliveries of vascular origin. They are responsible for significant maternal-fetal morbidity/mortality. Data published in 2007 by the Haute Autorité de Santé (HAS) show that hypertension and pre-eclampsia are, in France, at the origin of 3 to 8% of the risk of perinatal mortality. During pregnancy, a transitional organ of foetal origin, the placenta, is established, which is essential for the maintenance and harmonious development of the pregnancy. The chorionic villus, in contact with maternal blood in the intervillous chamber, is the structural and functional unit of the placenta. After the initial implantation phase, the trophoblastic cell constituting the main part of the placental villi differs in two ways: (A) into "citrus cytotrophoblasts" whose cells will fuse to generate the multinucleated outer layer giving the syncytiotrophoblast that ensures fetal-maternal exchanges and endocrine functions of the placenta; (B) into "invasive extra-city cytotrophoblasts" essential for the effective anchoring of the placenta in the decidualized uterine mucosa and for the remodelling of the terminal uterine spiral arteries, whose resistance to blood flow must collapse to allow effective oxygenation of the villi. Extra-city trophoblasts change from an epithelial phenotype to an endothelial phenotype. They may thus be exposed to pro-thrombotic factors such as endothelial cells. A lack of trophoblastic invasion and incomplete remodelling of the spiral uterine arteries are responsible for placental hypo-perfusion, hypoxia and the occurrence of placenta-mediated pathologies (pre-eclampsia, intrauterine growth retardation, retroplacental hematoma, fetal loss and fetal death in utero). The most common placental-mediated disease is pre-eclampsia (5% of births). It corresponds to a complication occurring from the second trimester of pregnancy and which is clinically characterized by high blood pressure, oedema and proteinuria. It is responsible for premature deliveries and is a major cause of intrauterine growth restriction. To date, there is no specific and early biomarker for the occurrence of placental vascular pathologies. Recent developments raise, for example, the question of circulating angiogenesis inhibitory factors (sFlt1, sEng) in pre-eclampsia. With regard to treatment, early administration of low-dose aspirin before 16 weeks of pregnancy seems to reduce the risk of pre-eclampsia, hence the importance of having very early markers of the disease. Discovering such markers is therefore one of the major challenges in strengthening women's follow-up and avoiding subsequent complications. For fetal losses and retroplacental hematoma, the administration of low molecular weight heparin has been shown to be effective. However, these treatments are not specific to placental vascular pathologies. Thus, understanding and exploring the cellular and molecular mechanisms of vascular-placental interface dysfunctions remains necessary to enable targeted management of patients feeding the general principle of precision medicine. Compare the concentrations of (i) circulating histones involved in inflammation, proliferation, migration or cell differentiation (H3-citrullinated histone, acetylated histones (Pan-histones), H1 histone) and (ii) free HMGB1 protein between the three patient groups ("GrossN", "GrossC", "VolS"). The histones H3-citrullinated, acetylated histones (Pan-histones), H1 histone as well as the free HMGB1 protein will be quantified. This choice corresponds to the histones involved in inflammation, proliferation, migration or cell differentiation and can be quantified to date.
The researchers would like to know how long pregnant women spend in different positions during the night - and how often women change positions - across pregnancy. The researchers also want to see if the sleep monitor is able to improve sleep behaviors
The Umeed-e-Nau (UeN) initiative aims to support the introduction, scale up, and further piloting of high quality and high impact interventions to improve Maternal, Newborn And Child Health (MNCH)in Pakistan by harnessing the potential of both public and private sectors, coupled with introduction of women and girls empowerment interventions. UeN has two major components: 1) Introducing proven effective MNCH interventions at scale in 8 rural districts of Pakistan, and 2) Generating evidence on innovative approaches to improve MNCH while included in public health programs in Pakistan. There are six trials that are being conducted to address different evidences gaps to improve maternal, newborn and child health in Pakistan. The protocols of the trials will be registered separately.
Purpose: The investigators hypothesize that a simple, personalized, smartphone-based activity intervention using a wrist-based activity tracker will help high risk pregnant women reduce their stress during pregnancy. Participants: Pregnant women enrolled in prenatal care at the University of North Carolina who have a documented moderate or high level of perceived stress ( ≥ 14) and are at high risk for adverse pregnancy outcomes due to body mass index of ≥ 30 kg/m2 or history of gestational hypertension, preeclampsia, intrauterine growth restriction, or preterm birth <37 weeks' in a prior pregnancy. Procedures: Women meeting inclusion criteria will be recruited through the University of North Carolina prenatal care clinics. They will be contacted for possible participation at regularly scheduled prenatal visits and/or ultrasound. They may also be contacted for possible participation by remote methods (e.g., Telehealth). Women who are enrolled will complete validated dietary, stress, sleep, and body image questionnaires. Enrolled women will then be randomized to receive standard obstetrical care or enhanced counseling. All participants will receive a wrist-based activity tracker. Maternal blood sample for biochemical markers of stress and gene expression will be obtained at the initial visit; a followup blood sample will be obtained later in pregnancy, and a small portion of the placenta saved at delivery. Maternal and neonatal outcomes will be compared between groups.
In patients with suspected placental vascular disease who do not require hospitalization, the use of the sFlt-1 (Soluble FMS like tyrosin-kinase-1)/PlGF (Placental Growth Factor)/ assay can most likely help teams to define the best possible management.
