PURPOSE: To compare the clinical effect of emergency cervical cerclage and elective cervical cerclage on pregnancy outcome in the cervical-incompetent pregnant women. METHODS: Literature was searched from the databases of Pubmed, Embase and Google scholar. The fixed or random effects model was used to calculate pooled risk ratios on the basis of heterogeneity. Meta-regression, sensitive analysis, subgroup analysis, and publication bias assessment were also conducted to confirm the results according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009...

BACKGROUND: It has been suggested that cervical ripening with a balloon catheter for labour induction can be done in an outpatient setting in low-risk pregnancies. Introduction of such an approach needs to be accompanied with monitoring of potential complications. Therefore the existence and frequency of any associated adverse event during cervical ripening needs to be established. OBJECTIVE: To assess the complication rate during cervical ripening with balloon induction...

Introduction: It is well known that cervical incompetence and associated preterm birth confers greater morbidity and mortality on birth outcomes, with an additional increased risk of cervical incompetence in higher order gestations. While the pathophysiology of cervical incompetence has yet to be elucidated, research has identified risk factors and assessed outcomes of numerous interventions. Cervical cerclage has been shown, in certain situations involving singleton pregnancies, to improve outcomes...

Introduction: Preterm delivery remains a challenge in Obstetrics as it is responsible for significant cause of perinatal morbidity and mortality. At present there is no standard test for prediction of preterm labour for timely referral to a center with NICU facilities. Aim: To evaluate the effectiveness of the cervical phosphorylated insulin like growth factor binding protein-1(phIGFBP-1), cervical length measurement and combination of phIGFBP-1 with cervical length for Predicting Preterm Labour (PTL)...

BACKGROUND: A midtrimester cervical length (CL) <25 mm is associated with spontaneous preterm birth (sPTB). However, as CL ≥25 mm is not enough to exclude recurrence in high-risk patients, follow-up CL measurement later in pregnancy has been proposed. OBJECTIVES: To evaluate whether CL measurement at 26±1 weeks in asymptomatic high-risk patients improves the prediction of sPTB recurrence. METHODS: A retrospective cohort of high-risk women because of previous sPTB was analyzed...

OBJECTIVE: to investigate whether serum relaxin is associated with preterm birth in symptomatic women, either as a standalone test or in the context of a combined model. METHODS: This was a case-control study of women with singleton pregnancy, who presented between 24+0 and 26+6 weeks with threatened preterm labor and intact membranes. Cervical length, full blood count, C-reactive protein and maternal demographics were recorded at presentation. Blood samples were taken for relaxin and these parameters were compared between women who delivered <37 weeks (N=46) and women delivering at term (N=66)...

OBJECTIVE: There is a paucity of head-to-head randomized trials that compare single- and double-balloon catheters, and the results of the available data in terms of time from catheter insertion to delivery and delivery mode are mixed. This meta-analysis of randomized controlled trials compares the efficacy of single- and double-balloon catheters in women undergoing labor induction. STUDY DESIGN: Searches were made in MEDLINE, EMBASE, PubMed, ClinicalTrials.gov, and the Cochrane Library from inception through June 2016...

Water is the major component of cells and tissues, and the movement of water across the cell membrane is a fundamental property of life. Until the discovery of the first water channel, aquaporin, it was long assumed that the transport of water was due to simple diffusion through the lipid bilayer membrane that encloses cells. Aquaporin (AQP) molecules were first discovered in the human uterus in 1994, and since then several studies have investigated these channels in the female reproductive system. The expressions of AQPs have been proven in the reproductive system...

Preterm birth (PTB), or birth before 37 weeks gestation, is the leading cause of neonatal mortality worldwide. Cervical viral infections have been established as risk factors for PTB in women, although the mechanism leading to increased risk is unknown. Using a mouse model of pregnancy, we determined that intra-vaginal HSV2 infection caused increased rates of preterm birth following an intra-vaginal bacterial infection. HSV2 infection resulted in histological changes in the cervix mimicking cervical ripening, including significant collagen remodeling and increased hyaluronic acid synthesis...

PURPOSE: The role of cervical cerclage to prevent preterm birth (PTB) remains controversial. The aim of this study was to identify prognostic factors for cerclage failure among singleton pregnant women following prophylactic cerclage (PC). METHODS: A retrospective analysis of PC was performed in a single center. The main outcome measure was cerclage failure, defined by spontaneous early PTB prior to 32 weeks' gestation. Age, BMI, history of instrumentation of the uterus, history of second trimester miscarriage, previous conization, positive vaginal swab prior cerclage, gestational age at time of cerclage, CRP 1 week after cerclage and post-cerclage US changes of cervical length were tested as predictive factors...

Objective: To identify factors associated with massive postpartum bleeding in pregnancies complicated by incomplete placenta previa located on the posterior uterine wall. Methods: A retrospective case-control study was performed. We identified 210 healthy singleton pregnancies with incomplete placenta previa located on the posterior uterine wall, who underwent elective or emergency cesarean section after 24 weeks of gestation between January 2006 and April 2016...

Precise prediction of the time of onset of parturition in the bitch is of clinical importance. Many parturition management cases in clinical practice are presented in the last two weeks of pregnancy without a reliable estimate of the parturition date. The aim of this study was to assess the value of a single progesterone level in the blood plasma from a preparturient bitch to predict the time of onset of parturition. The temporal relationship between the decrease in the plasma progesterone levels and the time of cervical dilatation (TCD)-which correlates to the onset of stage 1 of parturition-was evaluated in 25 bitches in the preparturient period...

Sleep disordered breathing (SDB) and obstructive sleep apnea (OSA) during pregnancy are growing health concerns because these conditions are associated with adverse outcomes for newborn infants. SDB/OSA during pregnancy exposes the mother and the fetus to intermittent hypoxia. Direct exposure of adults and neonates to IH causes neuroinflammation and neuronal apoptosis, and exposure to IH during gestation (GIH) causes long-term deficits in offspring respiratory function. However, the role of neuroinflammation in CNS respiratory control centers of GIH offspring has not been investigated...

There is increasing concern about Mycoplasma genitalium as a cause of urethritis, cervicitis, pelvic inflammatory disease (PID), infertility and ectopic pregnancy. Commercial nucleic acid amplification tests (NAATs) are becoming available, and their use in screening for M. genitalium has been advocated, but M. genitalium's natural history is poorly-understood, making screening's effectiveness unclear. We used a transmission-dynamic compartmental model to synthesise evidence from surveillance data and epidemiological and behavioural studies to better understand M...
