Active clinical trials for "Obstetric Labor, Premature"

Preterm delivery occurs in about 5-18% of pregnancies before 37 weeks' gestation all over the world.It is associated with a high prevalence of neurological deficits, developmental disabilities and is a leading cause of infant and neonatal mortality. Many of the methods used for predicting preterm birth has not been proven efficacy and is not currently recommended for use.The length of the cervix has been one of the most useful methods in predicting the risk of premature delivery. Detection rates may be improved if combined with other parameters such as the uterocervical angle as a new predictor of spontaneous preterm birth. In this study we will compare between using the uterocervical angle and cervical length in the prediction of preterm labour.

This is a prospective observational case controlled study. The control group will include pregnant women, having intact membranes and are at risk of or in preterm labour, administrating the standard treatments for prolongation of pregnancy. The test group will involve pregnant women, having intact membranes and are at risk of or in preterm labour, administrating the standard treatments for prolongation of pregnancy plus azithromycin

Antenatal corticosteroids (ACS) reduce the risks of neonatal death and morbidities, such as respiratory distress syndrome, in preterm infants. Standard of care for women at risk of preterm birth includes 2 doses of 12 mg betamethasone (for a total of 24 mg) to accelerate fetal lung maturity. We plan to conduct a pilot clinical trial to determine the feasibility of a trial comparing half the usual dose (total 12 mg) of betamethasone to the standard double dose (total 24 mg) of betamethasone. The results of this pilot will be combined with the full-scale RCT (NCT05114096) for which we have received funding from the Canadian Institutes of Health Research (CIHR).

Investigators have shown the presence of elevated proinflammatory cytokines in amniotic fluid in patients in preterm labor.However, there is limited and mostly negative evidence that the elevation of these mediators in gingival crevicular fluid (GCF), and amniotic fluid are associated with pregnancy complications in periodontitis patients. Thus this case control study will be conducted to To determine the level of proinflammatory cytokines in gingival crevicular fluid in women with spontaneous preterm delivery with chronic periodontitis. To investigate the expression of macrophage inflammatory protein-1α in placental tissues. To assess the possible correlation between chronic periodontitis and preterm delivery.

Preterm delivery (PTD) is a leading cause of neonatal mortality and continues to be a major public health concern, reaching 12.9% in 2006, despite intense research to reverse this trend. Currently, fetal fibronectin (fFN) screening and cervical length determined by ultrasound are two tests which are proven to have benefit in the identification of those at greatest risk for preterm delivery. However the benefit of these tests is limited to situations where a negative result can avoid unnecessary interventions. Currently, maternal fetal monitoring is limited, as it is difficult to "see" what is going on in the placenta (maternal-fetal interface) without invasive measures such as placental biopsy or amniocentesis. Our goal for this study is to identify a group of biomarkers in non-invasive compartments (such as saliva, blood, urine, and/or cervical and vaginal secretions) that are associated with preterm labor and birth. We hypothesize that preterm labor will display an inflammatory profile, which consists of unique inflammatory biomarkers from different non-invasive bodily fluid compartments (such as Il-10 in urine, VEGF in cervical secretions, and IP-10 in saliva), that correlates with a high incidence of preterm birth.

Detection of short cervix by transvaginal ultrasound and its evidence based management to prevent preterm birth .

This will be a prospective study on labor characteristics, and obstetric and neonatal outcomes in women who accept and women who decline morphine as a form of pain management in labor. The study will also investigate patient satisfaction with this form of analgesia. The participants will be those who accept morphine and promethazine and those who decline morphine and promethazine for pain control.

This case control-study measures the levels of Interleukin-17 in gingival crevicular fluid and placental tissue samples of pregnant females as a possible marker in determining whether or not an association exists between chronic periodontitis and preterm labor. Interleukin-17 is a pro-inflammatory cytokine whose levels have been proven to increase in periodontal disease.

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

Study included all pregnant women admitted with threatened preterm labor during the study period. All participants underwent estimation of maternal serum homocysteine level and assessment of uterine artery Doppler indices.
