Objectives: To determine the cut off point of cervical length usingtransvaginal ultrasonography to predict the actual occurrence ofpreterm labor in women with threatened preterm labor. Methods: A cross sectional study with consecutive random samplingmethod. We examined 80 women with singleton pregnancycomplaining of regular, painful uterine contraction and rupturedmembrane at 24-36 weeks of gestation. Women in active labor, definedby the presence of cervical dilatation less than or equal 3 cm, and having complicationwere excluded. When the patient was admitted, a transvaginalscan was performed to measure the cervical length. Parenteralmagnesium sulfate was given as the subsequent management.The primary outcome was delivery within 24 hours of presentation.Results: We found that the optimal cut off values for cervical lengthwas 2.65 cm with sensitivity 94.4 Percent, specificity 65.4Percent, positive predictivevalue 75.4 Percent and negative predictive value 81.8 Percent. In 69cases, the cervical length was more than or 2.65 cm, with 52 patients successfullycontinued their pregnancy until more than 24 hours. In the 11cases with cervical length less than or equal 2.65 cm, delivery within 24 hours occurredin 9 cases (81,8 Percent). Conclusion: The findings of this study suggest that in women withthreatened preterm labor, cervical length more than or equal 2.65 cm may help predictthe actual occurrence of preterm labor.

Objective To quantify the degree of change in cervical length (CL) over a 3-minute transvaginal ultrasound. Study Design We conducted a prospective observational study of nulliparous patients who underwent routine transvaginal CL screening at the time of their second-trimester ultrasound. We recorded CL at four time points (0, 1, 2, 3 minutes) and compared these values to determine the minute-to-minute change within a single patient. Results A total of 771 patients were included. The mean gestational age was 20.8 weeks (±0.84). We used a linear mixed effect model to assess if each minute during the ultrasound is associated with a change in CL. The intraclass correlation coefficient between minute 0 to minute 3 was 0.82 (95% confidence interval: 0.80, 0.84). This indicates that there is a relatively high within-patient correlation in CL during their ultrasound. Additionally, we stratified patients based on their starting CL; the intraclass correlation coefficient remained high for all groups. We additionally compared CL at each minute. Although there is a statistically significant difference between several time points, the actual difference is small and not clinically meaningful. Conclusion The variation in CL over a 3-minute transvaginal ultrasound examination is not clinically significant. It may be reasonable to conduct this examination over a shorter period.

Abstract Introduction Thrombospondin 1, desmoplakin and stratifin are putative biomarkers for the prediction of preterm birth. This study aimed to validate the predictive capability of these biomarkers in patients at risk of preterm birth. Materials and Methods We included 109 women with symptoms of threatened spontaneous preterm birth between weeks 20 0/7 and 31 6/7 of gestation. Inclusion criteria were uterine contractions, cervical length of less than 25 mm, or a personal history of spontaneous preterm birth. Multiple gestations were also included. Samples of cervicovaginal fluid were taken before performing a digital examination and transvaginal ultrasound. Levels of cervicovaginal thrombospondin 1, desmoplakin and stratifin were quantified by enzyme-linked immunosorbent assays. The primary endpoint was spontaneous preterm birth before 34 + 0 weeks of gestation. Results Sixteen women (14.7%) delivered before 34 + 0 weeks. Median levels of thrombospondin 1 were higher in samples where birth occurred before 34 weeks vs. ≥ 34 weeks of gestation (4904 vs. 469 pg/mL, p < 0.001). Receiver operator characteristics analysis resulted in an area under the curve of 0.86 (p < 0.0001). At an optimal cut-off value of 2163 pg/mL, sensitivity, specificity, positive predictive value and negative predictive value were 0.94, 0.77, 0.42 and 0.99, respectively, with an adjusted odds ratio of 32.9 (95% CI: 3.1 – 345, p = 0.004). Multiple gestation, cervical length, and preterm labor had no impact on the results. Survival analysis revealed a predictive period of more than eight weeks. Levels of desmoplakin and stratifin did not differ between groups. Conclusion Thrombospondin 1 allowed long-term risk estimation of spontaneous preterm birth.
