Objective: The research was aimed to show about characteristics of subject, fetal fibronectin, vaginal pH, cervical length of women with threatened preterm labor, and which are become preterm labor? Preterm labor is occurs most often in 20 weeks gestation to less than 37 weeks gestation. This condition is concerned about Obstetric problem and associated with significant neonatal morbidity and mortality.Methods: This study used the design of case control where preterm pregnant women who become research subjects divided into two groups with threat and without the threat of pre-term labor. Fetal fibronectin , vaginal pHand cervical length than in both groups were evaluated as a risk factor for preterm labor. Mann-Whitney test , Wilcoxon test and Chi-squared test were used as statistical tests with a confidence level of 95%.Results: A total of 86 preterm pregnant women involved in this study with an average age 30 , 5 ± 6.25 (group threat) 32.16 ± 5.25 (non-threatening). Comparison of fetal fibronectin (p = 0.005), vaginal PH(p <0.001) and length of the cervix (p <0.001) between the two groups showed a significant difference. A total of 8 subjects of the 43 in the group of pregnant women with the threat pretem labor experiencing preterm labor .Conclusion: The size of a short cervical length, an increase in the pH of the vaginal secretions and increased levels of fetal fibronectin  is a clinical indicator for screening during pregnancy to assess the risk of a preterm labor .Keywords: cervical length, fetal fibronectin, pretermlabor , vaginal pH of the secretions. Abstrak Tujuan: Persalinan preterm adalah persalinan yang terjadi padausia kehamilan 20 hingga kurang dari37 minggu. Kondisi inimerupakanpermasalahan yang sangat mengkhawatirkan dalam bidang kebidanan dan dikaitkan dengan morbiditas dan kematian neonatal yang signifikan. Evaluasi dan skrining terhadap berbagai faktor resiko terjadinya ancaman persalinan preterm adalah hal terpenting dalam mencegah berbagai komplikasi yang mungkin timbul.Metode: Penelitian ini menggunakan desain case control dimana wanita hamil preterm yang menjadi subjek penelitian terbagi menjadi dua yakni kelompok dengan ancaman dan tanpa ancaman persalinan preterm. Fetal fibronectin, pH sekret vagina dan panjang serviks dibandingkan diatara kedua kelompok sebagai faktor resiko ancaman persalinan preterm. Mann-Whitney test, Wilcoxon test dan Chi – squared digunakan sebagai uji statistik dengan tingkat kepercayaan 95%.Hasil: Sebanyak 86 wanita hamil preterm terlibat dalam penelitian ini dengan rerata usia 30,5 ± 6,25 (kelompok ancaman) 32,16 ± 5,25 (tanpa ancaman). Perbandingan Fetal fibronectin (p=0,005), pH sekret vagina (p<0,001) dan panjang serviks (p<0,001) antar kedua kelompok menunjukkan adanya perbedaan yang bermakna. Sebanyak 8 subjek dari 43 pada kelompok wanita hamil pretem dengan ancaman persalinan preterm yang mengalami persalinan pretermKesimpulan:Ukuran panjang serviks yang pendek, peningkatan pH sekret vagina dan peningkatan kadar fetal fibronectin merupakan indikator klinis untuk skrining selama kehamilan guna menilai resiko terjadinya persalinan pretermKata kunci: fetal fibronectin, persalinan preterm, Ph vagina, panjang cerviks

Abstract Background Preterm birth is one of the major clinical problems in obstetrics and neonatology as it is associated with perinatal mortality, serious neonatal morbidity and in some cases childhood disability. It is reported that more than 80% of all neonatal mortality and morbidity is due to preterm birth. Objective In this study fetal adrenal gland volume and fetal zone measurement were used as a predictors for occurrence of labor in singleton pregnancies complicated by threatened preterm labor in comparison to cervical length and cervicovaginal fetal fibronectin. Methodology The study was carried out at Ain Shams University Maternity Hospital. The current study include 88 pregnant women who presented with symptoms or signs of threatened preterm labor (PTL). All women were subjected to full history taking, full general, abdominal, pelvic examination, in addition to ultrasound fetal biometry, measurement of cervical length, measurement of fetal fibronectin, fetal adrenal gland volume AGV and fetal zone acquisitions. Results Our results showed high statistically significant difference between the two groups of women regarding CL measurement, FZE and cAGV with P values &lt; 0.001 suggesting that ultrasound examination of fetal adrenal gland and assessment of FZE at time of evaluation for symptoms of PTL may be clinically beneficial in predicting the occurrence of labor in pregnant women at risk of preterm labor. Conclusion Our results demonstrate that in women presenting with threatened preterm labor, cAGV and FZE measured by 3-dimensional ultrasound seem to be significant predictors of delivery within 7 days, when compared to CL and cervicovaginal fetal fibronectin.

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.
