Introduction. The cervical length is a predictor of premature delivery or abortion. In order to detect the risks of such complications, it is necessary to establish the factors affecting the length of the cervix. Material and methods. A transversal prospective study was carried out in a sample of 579 pregnant women with low risk, singleton pregnancies of various gestational ages. Cervical length was measured by transvaginal ultrasound as part of routine pregnancy monitoring. At the same time, data on previous first-trimester or mid-trimester abortions, as well as on premature deliveries and term deliveries, were collected and taken into consideration. Results. The cervical length in primiparous women was not statistically significantly longer than in women with a previous pregnancy, except during the second trimester, (primiparous women: 33.8 mm. women with a previous pregnancy: 35.8 mm). Bearing in mind the empirical facts that the cervix in primiparous women. since intact, is significantly longer, the above mentioned findings cannot be easily explained. The cervix in women with a previous vaginal delivery was statistically significantly longer (35.6 mm) than in women with no vaginal delivery (34.09) (p=0.0l 1). In women with previous abortions of any kind, the cervical length was 34.2 mm. The cervical length in women without previous abortions was 34. 7 mm, and there were no significant differences. Moreover, no statistically significant differences were established in women with or without previous abortions, regardless of the type. Conclusion. Taking into consideration the data from previous obstetric histories, the results of our study indicate that cervices of women. .

Background: The aim of the study was to find out pre-induction cervical length by TV Sonography, determine Bishops score and to co-relate the obstetric outcome with these two variables.Methods: A study was done on 100 women with singleton pregnancies at 37-42 weeks of gestation, admitted for induction of labour in the Department of Obstetrics and Gynaecology at SGRDIMSR, Vallah, Amritsar, Punjab, India. All women underwent cervical assessment by both transvaginal ultrasound and Bishop Score and the outcome of labour induction was determined.Results: Of the 100 women, 53 women had vaginal delivery and 47 landed into LSCS. Bishop score < 6 and cervical length > 3 cm are cut off values of cervical unfavourablity. Successful induction was achieved among 87.5% and 78% women with favorable cervix according to Bishop Score and Cervical length respectively .Among the 92 and 50 women with unfavourable cervix according to Bishop score and cervical length, 48 (52.17%) and 14 (28%) had vaginal delivery respectively.Conclusions: Hence, cervical length by transvaginal ultrasound is a better predictor for the success of induction of labour as compared with assessment by Bishop Score alone.

Objective: To examine the value of the cervical length (CL) measurement at 24-30 gestational weeks in the prediction of spontaneous preterm delivery (SPD) between 30 and 34 weeks (SPD34) and between 34 and 37 weeks (SPD37). Methods: We performed a prospective cross-sectional study. CL was measured once by transvaginal ultrasound examination between 24 and 30 weeks. Results: The study sample consisted of 1,180 low-risk singleton pregnancies. 10 women (0.85%) had a SPD34 and 60 (5.08%) had a SPD37. CL was shorter (p < 0.001) in the women who had a SPD34 (median 11 mm) compared to the women who delivered after 34 weeks (median 31 mm). CL was shorter (p < 0.001) in the women who had a SPD37 (median 22 mm) compared to the women who delivered after 37 weeks (median 31 mm). CL predicted SPD34 (OR = 0.837, R2 = 0.2768, AUC = 0.9406, p < 0.001) and SPD37 (OR = 0.907, R2 = 0.1085, AUC = 0.7584, p < 0.001). The model achieved a sensitivity of 70.0 and 38.3% for 10% false-positive rate for SPD34 and SPD37, respectively. Conclusions: CL after 24 weeks is significantly shorter in women destined to have a SPD. In low-risk singleton pregnancies CL performs very well in predicting SPD34 and adequately in predicting SPD37.

Abstract Purpose To compare the techniques for cone measurement with ultrasound to determine the size of the resected tissue and to evaluate parameters which may be relevant for stratifying women at risk who need surveillance when pregnant. Methods The present study included women with a pathological cervical biopsy. Cervical length and volume were determined by transvaginal ultrasound prior to conization. The pathologist measured the volume of the removed tissue by the fluid displacement technique and using a ruler. A repeat transvaginal ultrasound was performed during a follow-up visit. Factors affecting cone volume as well as the correlation between measurement techniques were analyzed. Results A total of 28 patients underwent cervical excision treatment. The mean cervical volumes measured sonographically before and after the operation were 17.72 ± 7.34 and 13.21 ± 5.43 cm3, respectively. The proportion of volume excised was 25.50 ± 17.43%. A significant correlation was found between the cone depth and the cone volume measured by the fluid displacement technique, and histopathologically and sonographically measured difference in cervical volume. The interobserver reliability coefficient was > 0.9. Analyzing influential parameters, only age affected the extent of cone volume and the correlation between the three measurement techniques. Conclusion Commonly applied techniques of cervical and cone measurement are equivalent and interchangeable. Our ultrasound data show variety in the volume and length of the cervix, and in the proportion of the volume excised at conization. Ultrasound measurements may help the surgeon to estimate not only the dimension of the remaining cervix but also its function.

AbstractPartoSure is a bedside test for the prediction of time-to-spontaneous preterm delivery by the detection of placental alpha microglobulin-1 (PAMG-1). The objectives of this study were to further determine the test’s efficacy in predicting delivery within 7 or 14 days from testing, and to compare it with fetal fibronectin (fFN) and cervical length (CL) measurement by transvaginal ultrasound.The study population consisted of 203 consecutively recruited women with singleton pregnancies between 20The sensitivities for PartoSure (n=203), fFN (n=66), and CL (n=203) for predicting imminent spontaneous preterm delivery within 7 days were 80%, 50%, and 57%, respectively. The specificities were 95%, 72%, and 73% for PartoSure, fFN and CL, respectively. The NPVs were 96%, 87%, and 89% for PartoSure, fFN and CL, respectively. The PPVs were 76%, 29%, and 30% for PartoSure, fFN and CL, respectively.PAMG-1 detection by PartoSure is the single best predictor of imminent spontaneous delivery within 7 days compared to fFN and CL. In settings where CL is used as an initial screen, PartoSure has the greatest clinical utility in patients with CL between 15 and 35 mm. In situations where CL is not an initial screen, PartoSure is the most accurate test compared to fFN and CL.

Abstract Introduction: Cervical cerclage and vaginal progesterone are two primary methods for preventing preterm birth. However, their effectiveness in preventing singleton pregnancies with a short cervical length is unclear. We compared the effects of cervical cerclage and vaginal progesterone on the mother and neonate in asymptomatic singleton pregnancies in women with a cervical length between 10–30 mm.Material and Methods: Asymptomatic singleton pregnant women with a cervical length of 10–30 mm, measured using transvaginal ultrasound at 12–26 weeks of gestation, who delivered at our hospital were enrolled. The primary outcome measure was preterm birth at <37, 34, 32, and 28 weeks of gestation. The secondary outcome measures were neonatal mortality, latency period from diagnosis to delivery, hemorrhage during delivery, birth weight, and cesarean delivery.Results: In the unadjusted analysis, the number of preterm births was significantly higher in the cerclage group than in the vaginal progesterone group. After multivariate adjustment for confounding factors, this relationship narrowed. The latency period from diagnosis to delivery was significantly prolonged.Conclusions: Cervical cerclage showed no benefit over vaginal progesterone in preventing preterm birth. However, it prolonged gestational age by 39 days compared to vaginal progesterone treatment.

ABSTRACT Prevention of preterm labor will reduce perinatal mortality. Screening of cervical length by ultrasound should begin at 16 weeks by transvaginal ultrasound. If the cervical length is more than 35 mm, the exam should be repeated every 2 to 3 weeks till 32 weeks. If the cervical length is between 25 and 35 mm the ultrasound screening should be done weekly or biweekly. Fetal fibronectin estimation should provide supplemental information. If the cervical length is less than 25 mm cervical cerclage should be performed if gestational age is less than 22 weeks. Progesterone therapy is preferred if the gestational age is more than 22 completed weeks.

We previously reported a logistic regression model for prediction of GDM from maternal characteristics and medical history in 75,161 singleton pregnancies. In this study of 1376 twin and 13,760 singleton pregnancies recruited at 11–13 weeks’ gestation, we extend the model to include terms for twin pregnancies. We found the respective odds of GDM in dichorionic and monochorionic twin pregnancies to be 1.36 (95% CI: 1.02–1.81) and 2.78 (95% CI: 1.72–4.48) times higher than in singleton pregnancies. In both singleton and twin pregnancies, the risk for GDM increased with maternal age and weight and birth weight z-score of a baby in a previous pregnancy and is higher in women with a previous pregnancy complicated by GDM; in those with a first- or second-degree relative with diabetes mellitus; in women of Black, East Asian, and South Asian racial origin; and in pregnancies conceived through the use of ovulation-induction drugs. In singleton pregnancies, at 10% and 20% false-positive rate, the detection rate was 43% and 58%, respectively. In twin pregnancies, using risk cut-offs corresponding to 10% and 20% false-positive rates in singletons, the respective false-positive rates were 27% and 47%, and the detection rates were 63% and 81%.
