Filter by:Preterm birth (PTB) is the primary cause of infant death worldwide. It has been shown that a vaginal microbiota deplete in Lactobacillus species is a risk factor for preterm labour. Conversely a vaginal microbiota dominated by Lactobacillus crispatus appears to be protective for these adverse outcomes. A wide range of 'over the counter' Lactobacillus spp. containing products targeted at 'vaginal health' and formulated for vaginal administration are available, but most of them do not contain vaginal species of Lactobacillus. The primary aim of this study is to determine whether vaginal supplementation with L. crispatus CTV-05 is associated with colonisation.
The aim of this study is to Determine whether cerclage with vaginal progesterone will: 1. Reduce the overall spontaneous preterm birth rate. 2. Prolong pregnancy latency. 3. Improve neonatal outcome. Compared to vaginal progesterone only, in patients with progressive cervical shortening. Research question: Does cervical cerclage reduce the overall spontaneous preterm births in patients with progressive cervical shortening. Research Hypothesis In this current study, the investigators hypothesize that cervical cerclage reduces spontaneous preterm births in patients with progressive cervical shortening on vaginal progesterone only.
The objective of the present study is to evaluate the effectiveness of two doses of vaginal progesterone(200mg versus400mg) and placebo in improving gestational age in twin pregnancy and its subsequent impact on perinatal outcome.
Assessment of correlation between vitamin D level and prevalence of preterm births remains limited. The exact role of vitamin D in preterm birth has not yet been clearly defined ,where some studies showed vitamin D deficiency increased the risk of preterm birth while other studies found no correlation. In this study will try to continue research on this subject.
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.
The primary purpose of the protocol is to compare the diagnostic accuracy in terms of positive and negative predictive values of Premaquick © (combined detection of IL-6 / IGFBP-1 total / IGFBP-1 native) and Quikcheck fFN ™ (fibronectin detection) tests for prediction of spontaneous delivery within 7 days in women with threatened preterm labor. The study hypothesis is that combined detection of IL-6 / IGFBP-1 total / IGFBP-1 native dice the admission will improve the prediction of delivery compared to the detection of fetal fibronectin alone in women with threatened preterm labor.
Preterm birth is a common problem in obstetric care,with estimates ranging from 5% in several European countries to 18% in some African countries, Preterm labor defined as delivery before 37 completed weeks is the leading cause of perinatal and neonatal morbidity and mortality and strongly related to the developmental and neurological disabilities later in life.. There is still considerable uncertainty regarding the optimal progesterone type, route of administration, dosage and timing of start of therapy to prevent preterm labor in risky women
to test the hypothesis that activity restriction in women with singleton gestations and with arrested PTL would reduce the rate of PTB.
Preterm birth is defined as birth before 37 completed weeks of gestation .it occurs in 11.1%of birth globally affecting an estimated 14.9 million babies every year . It is generally accepted that approximately 65%-70%of preterm births are spontaneous,40%-45% of them due to spontaneous preterm labor and 25%-30%following preterm rupture of membranes.preterm birth represents the single largest cause of morbidity and mortality for newborn and is estimated for 29%of deaths in the first four weeks of life and also is estimated for of major cause of morbidity for pregnant women . Tocolytic agents include a wide range of drugs that can slow or suppress uterine contractions . Tocolytic are considered advantages in spontaneous preterm labor to : (a) allow time for the fetus to mature ,potentially avoiding deleterious effects of pre-maturity . (b)allow time for antenatal corticosteroids to be administered and have clinical effect. (c) allow time for intrauterine transfer to higher-care center where neonatal intensive care facilities are available . the ideal Tocolytic agent should be effective , easy to administer , without significant material ,fetal or neonatal side effects and permit time for antenatal corticosteroids to be administered and take effect . a variety of Tocolytic treatments have been used to inhibit uterine activity in women in spontaneous preterm labor , including betamimetics , calcium channel blockers , magnesium sulfate , prostaglandin inhibitors and oxytocin receptor antagonists however there is considerable global variation in types , doses and regimens of tocolytic agents uses to manage preterm labor . A comparison study between Ritodrine, magnesium sulfate and Nifedipine in terms of effect and morbidity will be conducted.
A comparative evaluation to evaluate the correlation between cervical cerclage or vaginal progesterone and maternal vaginal microbiome distribution during pregnancy
