“…Of the 18 full-text articles evaluated, four were excluded because patients with multiple pregnancies were includedin the studies [14][15][16][17], 1 because patients with both singleton and twin pregnancies were included [18], and 1 because it was difficult to determine the correlation between transabdominal Full-text article excluded with reasons (n = 10) 4 multiple pregnancy 1 both singleton and twin pregnancies 1 correlation between transabdominal and transvaginal sonography 3 included patients with transvaginal cerclage 1 idiopathic polyhydramnios and transvaginal sonography UCA measurement [19].

Objectives: In this meta-analysis, we aimedto demonstrate the relationship between uterocervical angle and preterm labor in singleton pregnancies more clearly and reliablywith this meta-analysis. Material and metods:In this study, we use keywords such as "uterocervical angle, " "cervical angle, " "angle, " "cervix, " "cervical, " "preterm, " and "preterm labour. " We searched various databases, including PubMed, MEDLINE, ClinicalKey, Scopus, ScienceDirect, Web of Science, and Google Scholar. The search encompassed the period from January 1, 2010, to December 27, 2020. As a result of the literature review, a total of 585 articles were identified. After the screening and selection process, six studies met the inclusion criteria and were included in the analysis. These six studies were deemed relevant and provided valuable information on the research topic.Results: When the Egger test (p = 0.020) and Begg test (p = 0.188) were performed, no significant publication bias was found in the studies examined. These statistical tests assess publication bias, and the resulting p-values indicate a low probability of bias in the included studies. Cochran's Q test revealed the presence of heterogeneity among the included studies. Heterogeneity indicates variability in the results beyond what would be expected by chance alone. This finding suggests that the studies may differ in methodologies, populations, or other factors, which could impact the overall results and require further investigation. There was a significant difference between the patient and control groups (p < 0.001). This result provides strong evidence to support the importance of the difference between the two groups compared. Conclusions:Based on the findings of this study, a wider uterocervical angle appeared to be significantly associated with an increased risk of preterm delivery in overall effect. It concluded that a wide uterocervical angle may be a potential risk factor for preterm delivery. Moreover, the study revealed a significant association between wider uterocervical angles and an elevated risk of preterm labour in singleton pregnancies. In this study, the definition of preterm birth accepts as birth before 37 weeks of gestation. These results highlight the potential significance of evaluating the uterocervical angle as a meaningful predictor for identifying the propensity of preterm labour in singleton pregnancies.

BACKGROUND: Pregnancy is an important process in women’s life, which is widely concerned by women. In recent years, the incidence of premature delivery (PTD) becomes more and more higher due to the development of auxiliary reproduction and ovulation induction technologies and the changes of pregnant women’s lifestyle and physical quality. PTD not only affects postpartum recovery and causes great physical pains, but it also has adverse effects on the birth state of neonates and even leads to neonatal death OBJECTIVE: The predictive values of cervix length (CL) measurement based on transvaginal ultrasonography (TVUS) and pathological examination of placenta for premature delivery (PTD) were investigated and the correlation between PTD and infection was analyzed. METHODS: 120 pregnant women with PTD or high-risk factors for PTD admitted to The Affiliated Hospital of Southwest Medical University between February 2020 and March 2022 were included as the subjects and underwent pathological examination of placenta and TVUS for CL measurement. The final gestational age was set as the standard for the evaluation on the predictive values of pathological examination of placenta and TVUS. What’s more, 36 subjects in PTD group and 84 in normal delivery group (control group) underwent pathological examination of placenta for the analysis of the correlation between PTD and infection. RESULTS: The joint inspection method showed significantly better sensitivity, specificity, PPV, and NPV compared to single CL or pathological examination of the placenta (P< 0.05). Among pregnant women, those with CL ⩽ 30 mm and positive placental pathology had a higher proportion compared to those with CL > 30 mm and negative placental pathology (P< 0.05). Furthermore, the incidence of Ureaplasma Urealyticum (UU), Chlamydia Trachomatis (CT), and Chorioamnionitis (CA) in vaginal discharge of the preterm delivery (PTD) group was significantly higher than that of the control group (P< 0.05). CONCLUSION: The combination of CL ⩽ 30 mm and positive placental pathology could effectively predict PTD and placental infection was notably correlated with the occurrence of PTD.
