Filter by:The purpose of this study is to determine whether fluoride supplementation during pregnancy is effective in extending the length of gestation and improving overall perinatal well-being.
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 1. To determine the level of proinflammatory cytokines in gingival crevicular fluid in women with spontaneous preterm delivery with chronic periodontitis. 2. To investigate the expression of macrophage inflammatory protein-1α in placental tissues. 3. To assess the possible correlation between chronic periodontitis and preterm delivery.
Patients diagnosed with arrested pre-term labor following tocolytics at 24-34 gestational weeks will be randomly allocated to receive either vaginal micronized progesterone 400 mg/day or no treatment.
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.
The purpose of this study is to evaluate the effect of oral progesterone supplementation in preterm labor on the prevention of recurrent uterine contraction and prolonging pregnancy period, and its side effect.
The purpose of this study is to determine if nifedipine treatment of women in preterm labor receiving corticosteroids results in postponement of delivery when compared to placebo.
This study looks at the effects of a mother's genes and other characteristics (mother's age, baby's age, race, and other diseases) on the ability of nifedipine to end contractions and prevent an early delivery. This information will be used to decide what amount of nifedipine women need to best treat preterm contractions.
Pharmacokinetics analysis and development of pharmacokinetics model in pregnancy women and fetus
Our objective is to investigate the predictive value of a panel of biomarkers associated with two biologically plausible pathways of preterm birth: membrane breakdown and cervical remodeling. The investigators will obtain cervical length, cervicovaginal fetal fibronectin, and a panel of novel cervicovaginal biomarkers associated with cervical remodeling in a prospective cohort of symptomatic women with a singleton pregnancy at high risk for preterm birth in an effort to better risk stratify this cohort.
Use of modern diagnostic tools e.g. fetal fibronectin and ultrasound measurement of cervical length to diagnose preterm labor can result in improved outcomes compared to traditional diagnosis based on digital examination to measure cervical change.
