Background: The majority of women who undergo induced abortion are young and of low parity. Hence, it is desirable to look for any association effects of induced abortion with future reproductive outcomes. In this study, we aim to compare ultrasound measured cervical length in pregnant women with previous induced abortion versus those who have not had an induced abortion.Methods: This was a prospective observational study performed at tertiary care hospital. Total of 400 patients were recruited, divided into two groups. Patients with an induced abortion in previous pregnancy were included as cases and those with no history were taken as controls. Cervical length was measured by transvaginal ultrasound in all participants at 11-14, 18-22 and 28-32 weeks. Pregnancies were followed up to note incidence of spontaneous preterm delivery, preterm pre labour rupture of membranes (PPROM), threatened preterm, and second trimester miscarriage.Results: Authors have found that there was no significant difference in the cervical length of pregnant patients with or without a history of prior induced abortions.  In our study authors found that mean cervical length at 11-14weeks, 18-22 weeks, and 28-32 weeks was 3.47±0.126cm and 3.48±0.195cm; 3.44±0.296cm and 3.49±0.182cm; 3.36±0.477cm and 3.42±0.310cm respectively among cases and controls. However, there was a demonstrably increased risk of spontaneous preterm delivery, PPROM and threatened preterm in patients with a history of prior induced abortion.Conclusions: Authors conclude that previous induced abortion increases the risk of threatened preterm, PPROM, spontaneous preterm delivery in the subsequent pregnancy. But, this risk is not predictable by measuring cervical length as the mean cervical length remained the same in both the groups.

Spontaneous Preterm Delivery

Introduction: Preterm birth is childbirth occurring at less than 37 completed weeks or 259 days of gestation, is a major determinant of neonatal mortality and morbidity and has long-term adverse consequences for health. Identifying ways to address preventable causes of preterm birth should be a top priority in developing regions of the world. the present study was planned to find the association between cervical length at 18 to 23 weeks of gestation done as a routine during all second level scans and spontaneous preterm delivery. Patients and Methods: This is a hospital based cross sectional study conducted during the period from January 2019 to December 2019. A total of 205 women presenting with singleton pregnancies between 18- 23 weeks of gestations were assessed by transvaginal ultrasound for the measurement of cervical length. Patients were interviewed and their demographic data such as age, obstetric index(GPALD), obstetric history such last menstrual period (LMP), estimated delivery date (EDD) and current pregnancy details such as BP, pulse rate, pallor, period of gestation, were recorded in a predesigned pro forma. Results: In a total of 205 subjects, the average age was found to be 23.26 ± 3.49 years with 52.2% of the women being primigravida. The mean gestation age at the time of enrollment was 20.72 ± 1.00 weeks with 33% of women showing a cervical length of 26-30 mm. The delivery outcome was found as 11% preterm, majority (89.27%) was term delivery. Conclusion: The present study showed that a significantly higher number of women with cervical length ≤ 30 mm (assessed at 18 to 23 weeks of gestation) had preterm labour compared to a woman with cervical length > 30 mm.

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.

Increased Risk

Measurement of the cervical length has become a central component of prenatal care. Mid-trimester cervical shortening is associated with preterm birth. This article summarizes a key study that established a strong correlation between cervical shortening and an increased risk of preterm birth. Transvaginal ultrasound was used to measure cervical length at 22 to 24 weeks’ gestation. The study showed that a short cervix was associated with an increased risk of preterm birth before 35 weeks. In addition, the shortest cervix conferred the highest risk, suggesting an inverse relationship. This article concludes by summarizing how cervical length is incorporated into current clinical practice. Also, a clinical case is presented.

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.

Purpose To determine cervical biometry in pregnant women between 18 and 24 weeks of gestation and the ideal mode of measurement of cervical length in cases of curved and straight cervical morphology. Methods The uterine cervices of 752 low-risk pregnant women were assessed using transvaginal ultrasound in a prospective cross-sectional study. In women with straight uterine cervices, cervical biometry was performed in a continuous manner. In women with curved uterine cervices, the biometry was performed using both the continuous and segmented techniques (in segments joining the cervical os). Polynomial regression models were created to assess the correlation between the cervical length and gestational age. The paired Student t-test was used to compare measuring techniques. Results The cervical biometry results did not vary significantly with the gestational age and were best represented by linear regression (R2 = 0.0075 with the continuous technique, and R2 = 0.0017 with the segmented technique). Up to the 21st week of gestation, there was a predominance of curved uterine cervix morphology (58.9%), whereas the straight morphology predominated after this gestational age (54.2%). There was a significant difference between the continuous and the segmented measuring methods in all the assessed gestational ages (p < 0.001). Conclusion Cervical biometry in pregnant women between 18 and 24 weeks was represented by a linear regression, independently of the measuring mode. The ideal measuring technique was the transvaginal ultrasound performed at a gestational age ≥21 weeks.

Background: Preterm birth is one of the commonest causes of perinatal mortality. Cervical length is one of the major determinants of preterm delivery.Methods: This prospective observational study of 100 pregnant women attending ANC OPD was carried out at D.Y. Patil Hospital, Kolhapur. The pregnant women were scanned for cervical length between 11-14 weeks and 20-22 weeks of gestation, using USG machine with TVS probe (mindray DC-7).Results: The mean value of cervical length in pregnant women at 11-14 weeks was 3.94 cm and at 20-22 weeks of gestation it was 3.38 cm. There was shortening in the pregnant cervix from first to second trimester. In the study 12% of patients delivered prematurely who had reduction in cervical length from first trimester to second trimester. The inverse relation between the cervical length during pregnancy and frequency of preterm delivery was confirmed. The decrease in cervical length at 11-14 weeks of gestation and 20-22 weeks of gestation was useful for identifying patients at increased risk for pre-trerm.Conclusions: Our findings confirm those of previous studies that have found an inverse relation between the length of the cervix, as measured by transvaginal ultrasonography during pregnancy, and the frequency of preterm delivery. We found that the cervical length measured at 11-14 weeks and 20-22 weeks gestation was decreased in asymptomatic women with single to n pregnancies was useful for identifying patients at increased risk for preterm delivery.

Objective: Preterm birth is one of the major cause of perinatal morbidity and mortality. Clinical studies have pointed out the association between preterm birth and bacterial vaginosis (BV) infection. Our aim is to discover the incidence of BV and search for the mean cervical length and parameters for the prediction of preterm delivery. Materials and Methods: 130 pregnant woman between the 16th and 24th gestational week were included in our study. A detailed medical history was obtained from all of the women, and patients with a history of preterm delivery and the Vaginal Ph values and cervical length measurement were evaluated. Vaginal samples were analyzed, gram staining was performed, and a bacterial vaginosis diagnosis was made with Nugent’s criteria. Results:  Of 130 woman that we included in our study,  only 19 had bacterial vaginosis (14.6 %), and the mean cervical length was measured as 41.79 mm. Preterm birth occurred in nine of the pregnant women (6.9%), and no statistically significant difference was found between BV and shortened cervical length or preterm labor. When we excluded the known preterm birth risk factors from our study, we could not find a significant difference between preterm labor and BV. Conclusion:  We concluded that BV by itself is not a preterm risk factor. The frequency of BV in the pregnant women in our study group according to the preterm delivery rate and the mean cervical length were similar to those in international studies in which the relationship between cervical length and preterm delivery has been established. We did not come to a significant conclusion in our research; nevertheless, we can relate this result to the preterm delivery rate that is found to be lower than expected.
