A Prospective Study

Background: Preterm delivery (PTD) is a major cause of perinatal morbidity and mortality. Objective of present study was to identify the women at risk of preterm delivery with the help of trans-vaginal ultrasound by assessing cervical length changes, funneling of lower uterine segment, cervical dilatation.Methods: A prospective study was carried out over a period of 2 years on 50 patients with 24-36 weeks of gestation who clinically presented with signs of threatened preterm labor and were subjected to transvaginal sonographic measurement of cervical length.Results: Prediction of spontaneous preterm birth at <37 weeks of gestation with cervical length to be 2.75 cm has sensitivity of 95%, specificity of 96.5%, positive predictive value of 86.36% and negative predictive value of 98.7%.Conclusions: Transvaginal ultrasonography is the reliable, reproducible and objective method to assess cervix and to predict the risk of preterm delivery.

Preterm birth is the leading cause of death in newborns and the survivors are prone to health complications. Threatened preterm labor (TPL) is the most common cause of hospitalization in the second half of pregnancy. The current methods used in clinical practice to diagnose preterm labor, the Bishop score or cervical length, have high negative predictive values but not positive ones. In this work we analyzed the performance of computationally efficient classification algorithms, based on electrohysterographic recordings (EHG), such as random forest (RF), extreme learning machine (ELM) and K-nearest neighbors (KNN) for imminent labor (<7 days) prediction in women with TPL, using the 50th or 10th–90th percentiles of temporal, spectral and nonlinear EHG parameters with and without obstetric data inputs. Two criteria were assessed for the classifier design: F1-score and sensitivity. RFF1_2 and ELMF1_2 provided the highest F1-score values in the validation dataset, (88.17 ± 8.34% and 90.2 ± 4.43%) with the 50th percentile of EHG and obstetric inputs. ELMF1_2 outperformed RFF1_2 in sensitivity, being similar to those of ELMSens (sensitivity optimization). The 10th–90th percentiles did not provide a significant improvement over the 50th percentile. KNN performance was highly sensitive to the input dataset, with a high generalization capability.

Length Changes

Objective: This study aimed to determine differences in cervical length changes between administration of nifedipine and isoxsuprine. Method: Subjects of the study were pregnant women who meet the inclusion criteria (n=16). Treatments were given for 48 hours. Parameters measured was the cervical length before and after the administration of nifedipine and isoxsuprine. This study was conducted in Dr. Hasan Sadikin General Hospital from January until April 2020. Result: Less shortening of the cervical length after administration of tocolytic isoxsuprin for 48 hours compared with tocolytic nifedipine and statistically significant with p value of 0.0001 (p<0.05) using Paired T tests. Conclusion: Isoxsuprin is more effective to prevent shortening of the cervical length compared to nifedipine in cases of threatened preterm labor.
