NCT ID: NCT03501030 Recruiting - Preterm Birth Clinical Trials

Activity Restriction for Women With Arrested Preterm Labor

Start date: April 10, 2018
Phase: N/A
Study type: Interventional

to test the hypothesis that activity restriction in women with singleton gestations and with arrested PTL would reduce the rate of PTB.

NCT ID: NCT03480139 Recruiting - Pregnancy Clinical Trials

Biomarkers in Obstetrical Complications

Start date: April 25, 2018
Study type: Observational

Objective: To study the natural history of normal pregnancy and the most frequent pregnancy complications responsible for the excessive rate of perinatal morbidity and mortality, in order to develop models to predict the occurrence of these complications of pregnancy at the earliest possible time. The study focuses on the prediction of preterm labor with intact membranes, preterm prelabor rupture of membranes (PROM), preeclampsia, small for gestational age, gestational diabetes, and fetal death. These complications account for a minimum of $30 billion annually in the US alone. Study population: A cohort of pregnant women seeking care at the prenatal clinic of the Perinatology Research Branch in Detroit, Michigan. Design: A prospective observational cohort study of the natural history of women with a normal pregnancy, a history of adverse outcome, or those with a complication in the index pregnancy; therefore, this study will include nulliparous and parous women. Data will be collected at the time of clinic visits and will include interviews, clinical measurements, and ultrasound studies. We will assemble a biorepository of maternal biological fluids (blood, urine, saliva, cervicovaginal fluid, gingival crevicular fluid, swabs to characterize microbiota, amniotic fluid when a clinically indicated amniocentesis is performed). Placentas will be collected at the time of delivery as well as umbilical blood, and swabs to characterize the neonatal microbiota. We will use a retrospective case control and case-cohort design to generate models for the prediction of the most common pregnancy complications. These models will be developed by classifying obstetrical complications according to clinical presentation and histologic placental lesions. Models will be developed and subsequently validated in an independent cohort. Outcome measures: The goal is to develop sensitive, specific, and parsimonious predictive models to identify the patients at risk for developing complications of pregnancy using a combination of clinical and biological markers (biochemical and biophysical).

Transition to Home (TtH) After Preterm Birth

Start date: February 1, 2018
Phase: N/A
Study type: Interventional

Preterm birth is associated with significant and often life-long developmental, emotional and financial burdens. Preterm infants face several challenges that continue late into life, including developmental delays, social, and behavioural problems and poor academic performance. Parents also suffer considerable emotional and physical stress which in turn can have a negative impact on the child's development. In Switzerland, during the transition from hospital to home, there are not many interventions intended to improve mental health outcomes in parents or to promote positive parenting to improve developmental outcomes for the preterm infant. There are also few interventions to reduce associated health care costs. In order to improve parent and preterm infant outcomes, reduce hospital stay in the neonatal intensive care unit (NICU), lower readmission rates, and avoid unnecessary use of primary care resources a unique, new model of transitional care was developed. The new 'Transition to Home' (TtH) model makes use of well-tested, successful methods of post-discharge care. The investigators' study will evaluate the organizational and financial feasibility and cost effectiveness of the TtH model for infants born preterm by measuring the impact of an Advanced Practice Nurse (APN)-led intervention at the Children's University Hospital Bern. The intervention focuses on improving parental mental health and well-being, on infant growth and development, and on lowering overall costs. The investigators will gather data and then adapt and test the model within a longitudinal interventional comparative effectiveness study, and prepare it for other Cantons in Switzerland to implement.

NCT ID: NCT03443154 Not yet recruiting - Infection Clinical Trials

VF Test for Prediction of Extremely PTB After Cerclage

Start date: April 2018
Phase: N/A
Study type: Observational

The purpose of this research study is to determine if a vaginal fluid (VF) test can predict very early preterm birth in patients who are scheduled to have an exam indicated cerclage for severe cervical shortening. Prior to participants undergoing a scheduled amniocentesis two swabs to collect vaginal secretions for the VF tests will be done. During the amniocentesis your doctor will remove amniotic fluid as part of the routine clinical care. From that fluid sample, the study will use less than a quarter teaspoon for the amniotic fluid study test (AF test). Data regarding maternal and birth outcomes will be collected by medical record review.

Progesterone to Prevent Preterm Delivery

Start date: September 1, 2018
Phase: Phase 2/Phase 3
Study type: Interventional

Preterm birth (PTB) is a major challenge to perinatal health. It is defined as delivery before 37 completed gestational weeks. It accounts for 75% of perinatal deaths and more than 50% of long-term neurological disabilities, and it is the second most common cause of death in children under the age of 5 year. Neonates born preterm are at risk of respiratory distress syndrome, chronic lung disease, retinopathy of prematurity, necrotizing enterocolitis, intraventricular haemorrhage and sepsis in the short term, as well as cerebral palsy, motor and sensory impairment, learning difficulties, and increased risk of chronic disease in long run. It is estimated that the societal cost of PTB is $26 billion annually in the USA alone. Until now, prevention or reduction of PTB is based on identification of risk factors in obstetrical history, biochemical markers and short cervix. History of PTB and asymptomatic short cervix at the second trimester are both strong predictors for PTB. In women with asymptomatic short cervix at the second trimester, vaginal progesterone could effectively reduce PTB. Universal cervical length screening followed by treatment with vaginal progesterone has been shown to be the most cost effective strategy in preventing PTB. These findings were confirmed in meta-analysis. Nevertheless, only minority of women may benefit from progesterone treatment if it was being started at the second trimester. There is still a large proportion of PTB, which is currently not preventable, and the current approach to prevent PTB is far from ideal. One possible hypothesis is that the initiation of progesterone treatment would be too late for its effect to take place. Therefore, we decide to use oral progesterone in the current study. The objective of the study is to determine whether early use of progesterone can prevent PTB better when compared with universal screening of cervical length and followed by treatment with progesterone in those with short cervix.

Cervical Pessary Treatment for Prevention of s PTB in Twin Pregnancies on Children`s Long-Term Outcome

Start date: July 2018
Phase: N/A
Study type: Interventional

Preterm birth (PTB) complicates 13% of all pregnancies worldwide and is the most important cause of neonatal morbidity and mortality. Women with a twin pregnancy are at increased risk of preterm delivery. In the Netherlands, approximately 50% of women with a multiple pregnancy deliver before 37 weeks of gestation (WoG), of whom 9% deliver before 32 weeks. Evidence based treatment guidelines concerning prevention of PTB are not available in Europe. Expectant management is usual care with interventions only in terms of a tertiary prevention of PTB according to guidelines for premature rupture of membranes, premature labour or other pregnancy complications. The studies done on this topic included women at different stages of the second trimester so the question of the onset of cervix shortening and its impact on PTB is not answered yet. The critical period for a maximum impact of the pessary treatment on PTB is still to be verified. Up to now only the ProTwinTrial addressed the long-term outcome of the newborns, so here data and evidence is clearly missing. The investigators want to assess the impact of a cervical pessary treatment in twin pregnancies with cervical shortening on children's survival without neurodevelopmental disability at the age of 3 years at 3 different stages of the second trimester (16-20 (early) vs. 20-24 (middle) vs. 24-28 (late) weeks of gestation).

Prevention of sPTB With Early Cervical Pessary Treatment in Women at High Risk for PTB

Start date: June 2018
Phase: N/A
Study type: Interventional

Prevention of preterm birth (PTB) is a key factor for a positive short-term and long-term outcome of the newborn children as mortality and morbidity are inversely related to gestational age at delivery. Consequently every week of prolonged pregnancy will have a tremendous effect concerning the outcome of the new-borns, subsequently for their parents and society as well. The proposed RCT aims to evaluate the impact of a preventive pessary treatment on the prevention of preterm birth in women with a singleton pregnancy who are at high risk of spontaneous preterm birth (sPTB) due to a history of at least one previous preterm delivery and/or a history of previous cervical surgery. In accordance with the results by "van´t Hooft et al. 2016" an approximately 20% higher percentage of children's long-term survival without neurodevelopmental disability is expected for the pessary group in comparison with usual management (=control group) on basis of a reduction of prematurity < 34 week of gestation (WoG). The primary outcome measure for the effect of the pessary treatment in comparison to expectant management will be the children's long-term survival (3yrs) without neurodevelopmental disability. Secondary endpoints assess the impact of a preventive pessary placement on the prevention of preterm birth and its resulting risk on mortality and morbidity for the neonates.

Interest of a Vaginal Swab in Detection of Placental Alpha-Microglobulin-1 in the Prediction of Preterm Birth

Start date: February 24, 2018
Phase: N/A
Study type: Observational

Preterm labor is the first cause of hospitalization during the pregnancy, and at the origin of more than 60 000 births before 37 weeks of amenorrhea every year in France. It is however difficult to predict if a patient consulting in emergencies with symptoms of preterm labor, will give birth prematurely or not. Current diagnostic tools to identify patients with high risk of premature delivery in 7 days are insufficient because of their low positive predictive value. Yet the neonatal complications in case of premature delivery are important, with respiratory distress syndrome, hyaline membrane disease, necrotizing enterocolitis, intraventricular hemorrhage and post-natal death. Recent studies suggested that the detection of the placental alpha microglobulin 1 (PAMG-1) in the vaginal secretions, by Partosure® test at the women presenting symptoms of preterm labor with intact membranes would indicate that a premature spontaneous delivery could arise in 7 days with a good positive predictive value.The test is interesting all the more as the repetition of the prenatal cures of corticosteroids, aiming at the fetal lung maturation, is this day more recommended and as the beneficial effect takes place within 24 hours in 7 days following their administration. It seems thus essential to make studies to specify the interest of this test at the patients presenting a preterm labor. This study aims at estimating the diagnostic performance of the test of detection of PAMG-1 in the prediction of a delivery in 7 days, at the patients presenting symptoms of preterm labor.
