OBJECTIVE: To assess the effect of gestational age (GA) and cervical length (CL) measurements at transvaginal ultrasound (TVUS) in the prediction of preterm birth in twin pregnancy. DESIGN: Individual patient data (IPD) meta-analysis. SETTING: International multicentre study. POPULATION: Asymptomatic twin pregnancy. METHODS: MEDLINE and EMBASE searches were performed and IPD obtained from authors of relevant studies...

OBJECTIVE: We sought to determine whether cervical dysplasia in the absence of an excisional procedure is associated with an increased risk of preterm birth (PTB) and whether that risk is independent of the presence of a short cervix. STUDY DESIGN: This is a cohort study including women with a singleton pregnancy who underwent routine cervical length assessment between 18-23 6/7 weeks of gestation, stratified by cervical dysplasia (ie, no prior dysplasia, prior dysplasia but no excisional procedure, or prior excisional procedure)...

BACKGROUND: In twin pregnancies, the rates of adverse perinatal outcome and subsequent long-term morbidity are substantial, and mainly result from preterm birth (PTB). OBJECTIVES: To assess the effectiveness of progestogen treatment in the prevention of neonatal morbidity or PTB in twin pregnancies using individual participant data meta-analysis (IPDMA). SEARCH STRATEGY: We searched international scientific databases, trial registration websites, and references of identified articles...

Cervical pessary is a promising tool to prevent preterm birth in high risk pregnant women with shortened midtrimester ultrasonographic cervical length. It is well tolerated by women. PECEP and ProTWIN trials have opened new fields of clinical research. Their results suggest that cervical pessary may prevent preterm birth in women with (i) singleton and cervical length ≤25 mm at 18-22weeks, and with (ii) twins and cervical length ≤37mm at 16-22weeks. These results must be confirmed by other randomized controlled trial before a generalization of cervical pessary in these situations...

OBJECTIVE: The purpose of this study was to determine the effect of sexual intercourse on the accuracy of quantitative fetal fibronectin (qfFN) in the prediction of spontaneous preterm birth (sPTB) in asymptomatic high-risk women. STUDY DESIGN: This was a prospective masked predefined subanalysis of a larger study of cervicovaginal fluid qfFN concentration in high-risk women asymptomatic of preterm labor. Women who had sexual intercourse within 48 hours of qfFN testing (n = 61; 18(+0)-34(+6) weeks' gestation) were compared with controls from the same database without a history of pretest sexual intercourse, matched according to gestational age at testing and delivery, risk factor for sPTB, and ultrasonographic cervical length measurement...

Preterm birth remains a considerable public health concern and priority. Little headway has been made in the prevention of preterm birth despite considerable research in this area. New ideas and treatments are desperately needed. The pessary has emerged as a possible treatment for the prevention of preterm birth in both singleton and twin gestations. It appears to be low cost with minimal side effects. This review focuses on the available evidence for the use of cervical pessaries for the prevention of preterm birth, especially in a high-risk population with a shortened cervical length...

OBJECTIVE: To evaluate the use of Arabin cerclage pessary in the management of cervical insufficiency. METHODS: The pregnancy outcome of 20 women carrying singleton pregnancy referred for suspected cervical insufficiency and chose Arabin cerclage pessary for treatment from 2009-2011 were reviewed. Pregnancy outcome were analysed according to presence of risk factors, amniotic fluid sludge, cervical length and gestation at pessary insertion. RESULTS: At presentation, mean cervical length was 1...

OBJECTIVE: To compare the outcome of pregnancy in cohorts of women with singleton pregnancy and history of preterm birth and sonographic short cervix managed with different treatment protocols, namely cerclage, vaginal progesterone or cervical pessary. METHODS: This was a comparison of three management protocols for women with singleton pregnancy and a high risk of preterm birth because of a prior spontaneous preterm birth before 34 weeks and a shortened cervical length detected by transvaginal ultrasound...

Introduction. Reduction of preterm birth is a major goal in obstetric care. We performed a systematic review of randomized controlled trials and cohort studies on the effectiveness of the cervical pessary to prevent preterm birth. Methods. We searched the electronic databases of MEDLINE and Embase from inception until April 2012 to identify studies investigating treatment with a cervical pessary to prevent preterm birth. We constructed two-by-two tables for delivery before 28, 34, and 37 weeks of gestation and calculated relative risks (RRs) with 95% confidence intervals...

BACKGROUND: Preterm birth is a major health problem and contributes to more than 50% of the overall perinatal mortality. Preterm birth has multiple risk factors including cervical incompetence and multiple pregnancy. Different management strategies have been tried to prevent preterm birth, including cervical cerclage. Cervical cerclage is an invasive technique that needs anaesthesia and may be associated with complications. Moreover, there is still controversy regarding the efficacy and the group of patients that could benefit from this operation...

This Review describes the rationale for the use of cervical pessaries to prevent spontaneous preterm birth and their gradual introduction into clinical practice, discusses technical aspects of the more commonly used designs and provides guidance for their use and future evaluation. Possible advantages of cervical pessaries include the easy, 'one-off' application, good side-effect profile, good patient tolerance and relatively low cost compared with current alternatives. Use of transvaginal sonography to assess cervical length in the second trimester allows much better selection of patients who may benefit from the use of a cervical pessary, but future clinical trials are needed to establish clearly the role of pessaries as a preterm birth prevention strategy worldwide...

BACKGROUND: In women with a multiple pregnancy, spontaneous preterm delivery is the leading cause of perinatal morbidity and mortality. Interventions to reduce preterm birth in these women have not been successful. We assessed whether a cervical pessary could effectively prevent poor perinatal outcomes. METHODS: We undertook a multicentre, open-label randomised controlled trial in 40 hospitals in the Netherlands. We randomly assigned women with a multiple pregnancy between 12 and 20 weeks' gestation (1:1) to pessary or control groups, using a web-based application with a computer-generated list with random block sizes of two to four, stratified by hospital...

OBJECTIVE: No randomized controlled trial has compared vaginal progesterone and cervical cerclage directly for the prevention of preterm birth in women with a sonographic short cervix in the mid trimester, singleton gestation, and previous spontaneous preterm birth. We performed an indirect comparison of vaginal progesterone vs cerclage using placebo/no cerclage as the common comparator. STUDY DESIGN: Adjusted indirect metaanalysis of randomized controlled trials...
