Filter by:Currently, transvaginal cervical length measurement is used to screen in asymptomatic pregnant women with a history of PTB. In symptomatic women, presenting with threatened PTB cervical length in combination with the fibronectin test is used to identify women at high risk to deliver preterm. However, the predictive capacity of transvaginal cervical length measurement is limited. In pregnant women with a history of PTB, it only identifies a proportion of women who will have recurrent PTB. For symptomatic women, 30-60% of these women admitted to the hospital, do not deliver within seven days, leading to overtreatment of these women. Cervical softening is precursor of cervical shortening, effacement and dilatation and therefore cervical softening is a promising new marker that is based on tissue elasticity. However, the predictive value of cervical softening and the relation with spontaneous PTB still has to be determined. With the newly developed Pregnolia® System cervical softness could be measured on a standardized and safe manner. This study could help to improve care for women with a history of spontaneous PTB.
Effect of dexamethasone on fetal heart rate variability in case of preterm labour: prospective cohort study
Premature birth (PTB, birth before 37 weeks of pregnancy) is a global, yet unsolved, problem. With a global amount of approximately 15 M babies born prematurely, PTB is the leading cause of perinatal morbidity and mortality in many countries. Furthermore, premature babies often have complicated medical problems, especially those born very early. Some women spontaneously deliver prematurely without any symptom or sign of the imminent labor, whereas others present with symptoms of preterm labor (PTL). In the latter case, clinicians can intervene and treat the woman with tocolytics and antenatal corticosteroids in order to accelerate fetal lung maturation and reduce the risk of respiratory distress syndrome. However, one of the major challenges in the management of women presenting with symptoms of PTL is to distinguish between true and false PTL with the existing clinical methods (digital examination or transvaginal cervical length assessment). In fact, over 50% of the women presenting with PTL symptoms do not deliver prematurely and are still unnecessarily hospitalized and treated with corticosteroids as well as tocolytics, and only less than 10% of women give birth within 7 days of presentation. Unnecessary treatments and hospitalizations also result in increased health costs. Thus, there is a need for more accurate methods and tools to evaluate the cervical maturation status as indication of imminent labor in order to avoid unnecessary hospital admissions and therapy. Recently, cervical stiffness has been evaluated as more reliable tool for prediction of spontaneous preterm birth. Cervical stiffness can be evaluated using ultrasound by cervical elastography , but also by an aspiration technique-based method with a novel CE-marked device, the Pregnolia System. Thus, the aims of this study are to evaluate: - if the cervical stiffness measured with the Pregnolia System can differentiate between women with true PTL and those with false PTL, - if the knowledge of cervical stiffness improves the detection of women at true risk of spontaneous preterm birth in combination or over state of the art (e.g. cervical length on TVUS).
Objective: This trial is designed to compare between the effectiveness of nifedipine plus magnesium sulfate (MgSO4) and MgSO4 alone for tocolysis in women with threatened preterm labor. Patient Population: The population will include pregnant women at gestational age between 28 and 31 weeks who are 18 years old or older and have signs of threatened preterm labor. Study Design: This is a single-center, prospective, randomized controlled clinical trial. A total of 264 women pregnant between 28 and 31 weeks having threatened preterm labor will be enrolled and randomized into two parallel treatment arms. Patients in the group A will receive nifedipine plus MgSO4, while patients in group B will MgSO4 only. Treatment: All patients will be randomized on the day of enrollment. Patients with threatened preterm labor will receive the respective tocolysis in each group. All patients will receive corticosteroids for lung maturity according to the local protocol. Primary outcome: Number of women not delivered within 48 hours of starting tocolytic therapy. Secondary outcomes: perinatal mortality, a composite of adverse neonatal outcomes, birth weight, days on ventilation support, length of admission in neonatal intensive care, prolongation of pregnancy more than 7 days, delivery after 37 weeks of gestation, number of days till delivery, maternal mortality, maternal infection, and harm to mother from intervention.
Objective: This trial is designed to compare between the effectiveness of nifedipine versus magnesium sulfate (MgSO4) for tocolysis in women with threatened preterm labor.

The Periviable GOALS (Getting Optimal Alignment around Life Support) decision support tool (DST) is meant to facilitate informed shared decision-making regarding neonatal resuscitation for families facing the threat of a periviable delivery (deliveries occurring between 22 0/7 - 25 6/7 weeks gestational age). It is designed for parents to review independent of their clinician, and is intended to supplement, not replace, clinician counseling. The focus of the DST is the provision of patient-centered outcomes information and assistance with values clarification regarding neonatal outcomes. This is a multisite, randomized controlled trial to test the effect of the Periviable GOALS DST on shared decision making and decision satisfaction. The investigators hypothesize that participants who utilize the GOALS DST will have improved shared decision making and higher decision satisfaction.
This study through to the pregnant woman blood concentrations of dexamethasone therapy after research, explore the pharmacokinetic data of dexamethasone in pregnant women, Chinese pregnant women dexamethasone pharmacokinetic model, provide a reference for the clinical use of dexamethasone dose, through the biomarkers of dexamethasone to promote fetal lung maturity and other metabolomics, It provides the basis for the effectiveness and safety study of dexamethasone.
Azithromycin is an antibiotic that is effective against bacteria that been associated with preterm birth (PTB). The purpose of this study is to evaluate if the addition of azithromycin prior to exam indicated cerclage prolongs gestation. A cerclage is a suture placed in the cervix to prolong gestation.
Antenatal corticosteroids (ACS) reduce the risks of neonatal death and morbidities in preterm infants, such as respiratory distress syndrome. The standard of care for pregnant people at risk of preterm birth includes 2 doses of Celestone (for a total of 24 mg in Canada, or 22.8 mg in Australia) to accelerate fetal lung maturity. The investigators plan to conduct a randomized controlled trial to determine whether half the usual dose (12 mg in Canada, or 11.4 mg in Australia) of Celestone is non-inferior to the standard double doses.
The purpose of this study is to assess knowledge about emotional connection, attitude about relational health, and efficacy of Welch Emotional Connection Screen (WECS) training in the NICU. The investigators seek to discern if through this didactic training, frontline NICU clinicians can be taught to reliably use the WECS to rate parent-child relational health. Additionally, the investigators seek to learn if there is construct and theoretical validity of the hospitalized infant preterm WECS by correlating WECS scores to physiological, behavioral and mental health markers for parent and infant.
