[PMID: 39027507 PMCID: PMC11255580 DOI: 10.1016/j.heliyon.2024.e32923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 06/06/2024] [Accepted: 06/12/2024] [Indexed: 07/20/2024] Open
Abstract
Background Cervical insufficiency can lead to preterm birth and neonatal mortality. Emergency cervical cerclage is a surgical intervention aimed at preventing preterm birth in patients with cervical insufficiency. However, some patients may experience cerclage failure. This study aimed to identify the risk factors associated with cerclage failure and develop a predictive nomogram model for patients with cervical insufficiency undergoing emergency cervical cerclage. Methods Data of 200 patients who underwent emergency cervical cerclage for cervical insufficiency were retrospectively analyzed. Patients were categorized into successful and failed groups based on their ability to take the infant home. Univariate and multivariate logistic regression analyses were performed to identify risk factors for cerclage failure. A nomogram model was developed based on multivariate logistic regression results, and its performance was assessed using receiver operating characteristic curves, calibration plots, and decision curve analysis (DCA). Results Univariate logistic regression analysis identified 11 potential risk factors for cerclage failure, including the presence of polycystic ovary syndrome (PCOS), vaginitis, cervical dilation, preoperative C-reactive protein, routine vaginal lavage after cervical cerclage, delivery, gestational age, extended days, chorioamnionitis, intrauterine infection, cervical laceration, and premature rupture of membranes. Multivariate logistic regression analysis revealed that PCOS, cervical dilation after cervical cerclage were independent risk factors for cerclage failure while routine vaginal lavage was a protective factor against failure. The nomogram predictive model demonstrated an area under the curve value of 0.975, indicating excellent discriminatory ability. The calibration plot showed good consistency between the nomogram predictions and actual observations. DCA demonstrated the strong clinical applicability of the nomogram. Conclusions This study successfully identified risk factors associated with emergency cervical cerclage failure in patients with cervical insufficiency and developed a predictive nomogram model. This model can assist clinicians in making informed decisions and accurately predicting the risk of cerclage failure in these patients.

Abstract
The collagen type I alpha 1 (COL1A1, OMIM #120,150) gene, encoding the alpha-1 chain of type I collagen (UniProt #P02452), plays a key role in life-homeostasis due to its remarkable involvement in collagen synthesis. It is a promising candidate gene implicated in the pathogenesis of cervical insufficiency (CI). This study aimed to identify genetic variations within the COL1A1 gene that contribute to the development of CI. Polymerase chain reaction (PCR) and amplicon sequencing were implemented for single nucleotide polymorphisms (SNPs) detection (+ 1245G/T, SP1 rs1800012), which revealed wild-type sequence for targeted SNPs in enrolled proband indicated negative results regarding COL1A1 gene involvement for current form of CI. It allows further investigation of other closely connected genes probed in this study. Computational approaches viz. Protein-protein interaction (PPI), gene ontology (GO), and pathway participation were used to identify the crucial hub genes and signaling pathways for COL1A1 and CI. Using the Yet Another Scientific Artificial Reality Application (YASARA) software, molecular docking, and molecular dynamic (MD) simulation with the oxytocin (CID 439,302), estradiol (CID 129,728,744), progesterone (CID 5994) and hydroxyprogesterone (CID 150,788) were done. Interactive bioinformatics analysis demonstrated that the COL1A1 and more than 10 collagen sister genes had a strong connection with CI. In sum, the findings of this study provide insights into a modus operandi that can be utilized to illuminate the path toward studying sister genes and smooth diagnosis of CI. These findings have implications for understanding the foundational process of the condition and potentially developing screening, diagnostic, and therapeutic interventions. Graphical Abstract

Abstract
OBJECTIVE To study the guiding significance of medical history on laparoscopic and vaginal cervical cerclage in the treatment of cervical incompetence and its influence on pregnancy outcome. METHODS A total of 53 cases by laparoscopic abdominal cervical cerclage (LAC group) before pregnancy and 73 cases by transvaginal cervix cerclage (TVC group) at 12-14 weeks of pregnancy were collected. Multivariate logistic regression analysis was performed on the influencing factors of delivery gestational weeks. Furthermore, the gestational weeks after cervical cerclage were compared between the two groups with high- and low-risk grades. RESULTS The number of previous uterine cavity operations in LAC group was more than that TVC group, and the costs of operation were more than TVC group. At the same time, the hospitalization days and operation time were longer than those in TVC group, and the delivery rate of cesarean section was higher than TVC group, but the total hospitalization times were less than TVC group (P < 0.05). The rate of delivery before 34 weeks of pregnancy and the incidence of premature rupture of membranes or premature labor in LAC group were lower than those in TVC group (P < 0.05). In TVC group, the increased number of prior PTB or STL and the history of cervical cerclage failure would increase the risk of premature delivery before 34 weeks of pregnancy. There was no increased risk of preterm delivery before 34 weeks of pregnancy in LAC group (P > 0.05). According to the risk level, in the high-risk group, the delivery rate of LAC group at gestational weeks < 37 weeks, < 34 weeks and < 28 weeks was lower than that of TVC group. CONCLUSION Laparoscopic cervical cerclage might be more effective in preventing premature delivery before 34 weeks of gestation, and its influence on delivery gestational weeks was not affected by related medical history. For high-risk patients with the history of prior PTB or STL and failed cerclage, laparoscopic cervical cerclage might be more effective than vaginal cervical cerclage in preventing extremely preterm before 28 weeks, premature delivery before 34 weeks and premature delivery before 37 weeks. Therefore, our limited experience suggested that LAC can be a recommended option for patients with high-risk history.

Abstract
Background Congenital uterine anomalies (CUA) can be associated with impairments of early and late pregnancy events. Objective To assess the impact of CUA on reproductive outcomes in pregnancies conceived spontaneously or after assisted reproduction. Materials and Methods Systematic review and meta-analysis of cohort studies comparing patients with CUA versus women with normal uterus. A structured literature search was performed in leading scientific databases to identify prospective and retrospective studies. The Newcastle-Ottawa scale, adapted to AHRQ standards, was used to assess the risk of bias. Pooled odds ratios (OR) were calculated. Publication bias and statistical heterogeneity were assessed, and meta-regression was used to analyse the heterogeneity. Main outcome measures Miscarriage, ectopic pregnancy, placental abruption, term, and premature rupture of membranes (PROM), malpresentation at delivery, preterm delivery prior to 37, 34 and 32 weeks, caesarean delivery, intrauterine growth restriction/small for gestational age, foetal mortality and perinatal mortality. Results 32 studies were included. CUAs increased significantly the risk of first/second trimester miscarriage (OR:1.54;95%CI:1.14-2.07), placental abruption (OR:5.04;3.60-7.04), PROM (OR:1.71;1.34-2.18), foetal malpresentation at delivery (OR:21.04;10.95-40.44), preterm birth (adjusted OR:4.34;3.59-5.21), a caesarean delivery (adjusted OR:7.69;4.17-14.29), intrauterine growth restriction/small for gestational age (adjusted OR:50;6.11-424), foetal mortality (OR:2.07;1.56-2.73) and perinatal mortality (OR:3.28;2.01-5.36). Conclusions CUA increases the risk of complications during pregnancy, delivery, and postpartum. Complications most frequent in CUA patients were preterm delivery, foetal malpresentation, and caesarean delivery. What is new? Bicornuate uterus was associated with the highest number of adverse outcomes, followed by didelphys, subseptate and septate uterus.

Abstract
OBJECTIVE To evaluate live-birth rates per embryo transfer in patients with uterine Müllerian anomalies (UMAs). Secondary objectives were to compare reproductive outcomes between the normal uterus group, the different UMA types, and UMA subgroups with and without required surgery. DESIGN This retrospective study compared two cohorts, one with UMAs and other with normal uteri of our oocyte donation program at 12 Instituto Valenciano De Infertilidad/Reproductive Medicine Associates University affiliated clinics from January 2000 to 2020. The oocyte donation reduces confounding because of differences in embryo quality. The primary outcome was the live-birth rate per embryo transfer. Secondary outcomes included the rates of implantation, clinical pregnancy, miscarriage, and ongoing pregnancy. We calculated odds ratios with 95% confidence intervals. PATIENTS Infertile women undergoing oocyte donation with UMAs. INTERVENTION None. MAIN OUTCOME MEASURES The rates of implantation, clinical pregnancy, miscarriage, ongoing pregnancy, and live birth. RESULTS We analyzed 58,337 cycles of oocyte donation: 57,869 patients had no uterine malformation, and 468 women had UMAs. Compared with patients with normal uteri, patients with UMAs had lower rates of live births (36.67% [32.84-40.65] vs. 38.1% [95% confidence intervals {CI}: 37.82-38.42]) and ongoing pregnancy (39.74% [35.93-43.66] vs. 41.5% [41.24-41.83]). The miscarriage rate was higher in patients with UMAs (19.5% [16.55-22.85] vs. 16.6% [16.47-16.92]). Specifically, patients with a unicornuate uterus (n=29) had lower rates of implantation (24.07% [13.49-37.64] vs. 42.85% [95% CI: 42.6-43.09]), pregnancy (41.86% [27.01-57.87] vs. 59.51% [59.22-59.81]), ongoing pregnancy (16.67% [6.97-31.36] vs. 41.54% [41.24-41.83]), and live births (16.67% [6.97-31.36] vs. 38.12% [37.83-38.42]). In addition, patients with a partial septate uterus (n=91) had a higher miscarriage rate (26.50% [18.44-34.89] vs. 16.7% [16.47-16.92]). Compared with the normal uterus group, the live-birth rates were lower in the UMA without surgery group (33.09% [27.59-38.96] vs. 38.12% [37.83-38.42]). CONCLUSION Among patients who received embryos derived from donated oocytes, live birth and ongoing pregnancy rates were lower in patients with UMAs compared with patients with normal uteri. A higher miscarriage rate was found in patients with UMAs. Patients with a unicornuate uterus had worse reproductive outcomes. Our results show that the uterus is less competent in patients with UMAs. TRIAL REGISTRATION This study was registered at clinicaltrial.gov (NCT04571671).

Abstract
BACKGROUND To identify the effect and optimal time of cervical cerclage in asymptomatic twin pregnancies with cervical shortening or dilation. METHODS This observational retrospective study enrolled all women with asymptomatic twin pregnancies who were diagnosed with asymptomatic cervical shortening or dilation at the Second Affiliated Hospital of Wenzhou Medical University between 2010 and 2022. Women included were allocated into the cerclage group (n = 36) and the no cerclage group (n = 22). The cerclage group was further divided into the cerclage group (< 24 weeks group) and the cerclage group (24-28 weeks group) according to the time of cerclage. The no cerclage group was further divided into no cerclage group (< 24 weeks group) and no cerclage group (24-28 weeks group) according to the time of ultrasound-indicated or physical exam indicated cerclage. The rates of PTB < 24, 28, 32 and 34 weeks of gestation, maternal and neonatal outcomes were compared among the groups. RESULTS The gestational age (GA) at delivery was higher (P = 0.005) and the interval time between the presentation of the indicated cerclage and delivery was longer in the cerclage group (P < 0.001). The rates of PTB before 28, 32, and 34 weeks of gestation, caesarean section and stillbirth were lower in the cerclage group (P < 0.05). The birthweight of the twins was higher in the cerclage group (P = 0.012). Admissions to the NICU were more frequent in pregnancies with no cerclage (P = 0.008). Subgroup analysis showed that the interval time between the presentation and delivery was longer in the cerclage group (< 24 weeks) (P < 0.001). The GA at delivery and the birthweight of the twins were significantly higher in the cerclage group (< 24 weeks) (P < 0.001). No differences were found in the GA at presentation, the GA at delivery, the interval time between the presentation to delivery and birthweight between the cerclage group (24-28 weeks group) and the control group (24-28 weeks group) (P > 0.05). CONCLUSIONS Cerclage appears to prolong the GA at delivery and the interval time between the presentation to delivery, and may reduce the incidence of PTB before 28, 32 and 34 weeks of gestation and adverse perinatal outcomes in asymptomatic twin pregnancies with cervical shortening or dilation. Cerclage before 24 weeks of gestation showed longer GA at delivery, longer interval time between the presentation to delivery and higher birthweight of the twins. The GA at presentation, the GA at delivery, the interval time between the presentation to delivery and birthweight in women with cerclage at 24-28 weeks were similar to those in women without cerclage at 24-28 weeks.

Abstract
OBJECTIVES To explore maternal and neonatal outcomes in pregnant women with bicornuate uteri. METHODS Retrospective population-based cohort study utilizing data from the Healthcare-Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) from 2010 to 2014. There were 3,846,342 births between 2010 and 2014, included in the study. Six thousand and 195 deliveries were to women with bicornuate uterus. The remaining deliveries without other uterine anomalies were categorized as the reference group (n=3,840,147). RESULTS Pregnant women with bicornuate uterus were older and more likely to be obese (p=0.0001) with previous cesarean deliveries (CD) (31 vs. 17.1%, p=0.0001). After adjustment for confounders, they were more likely to experience pregnancy-induced hypertension (HTN) (aOR 1.21, 95%CI: 1.1-1.3), p=0.0001), preeclampsia (aOR 1.4, 95%CI: 1.2-1.6, p=0.0001) and placenta previa (aOR 1.7, 95%CI: 1.3-2.2, p=0.0001). Moreover, they were more likely to deliver preterm (aOR 2.8, 95%CI: 2.6-3.1, p=0.0001), deliver by CD (aOR 5, 95%CI: 3.1-4.1, p=0.0001), experience preterm pre-labor rupture of membranes (PPROM) (aOR 3.5, 95%CI: 2.6-3.1, p=0.0001), and have a placental abruption (aOR 3.0, 95%CI: 2.5-3.5, p=0.0001). There were increased risks of PPH (aOR 1.4, 95%CI: 1.2-1.6, p=0.0001), wound-complications (aOR 2.0, 95%CI: 1.5-2.7, p=0.0001), hysterectomy (aOR 2.6, 95%CI: 1.6-4.1, p=0.0001), blood-transfusion (aOR 1.7, 95%CI: 1.5-2.1, p=0.0001), and DIC (aOR 1.6, 95%CI: 1.1-2.5), p=0.014) in the group with bicornuate uteri. Also there was higher risk of SGA (aOR 2.9, 95%CI: 2.6-3.2, p=0.0001) and IUFD (aOR 2.5, 95%CI: 1.8-3.3, p=0.0001). CONCLUSIONS Bicornuate uteri can increase risks in pregnancy by many folds. Particularly risks of: premature delivery, CD, PPROM, placental abruption, hysterectomy, SGA and IUFD were increased 250-500%.

Abstract
OBJECTIVE To evaluate the feasibility and effectiveness of fetal reduction by transabdominal intracranial KCl injection for multifetal pregnancies in the early second trimester. METHODS The data of 363 patients who underwent transabdominal fetal reduction in the Reproductive Medical Center of Peking University Third Hospital from January 2006 to December 2019 were analyzed retrospectively. According to the location of fetal reduction, they were divided into two groups: Intracranial injection group (n=196) and intrathoracic injection group (n=167). The process of fetal reduction and pregnancy outcome of the two groups were compared. RESULTS There was no significant difference between the two groups in the average age and the proportion of type of infertility before assisted reproductive technology, conception method, indication for fetal reduction, starting number of fetuses, reduced number of fetuses, and finishing number of fetuses (P>0.05). There was no significant difference between the two groups in the proportion of the number of puncture ≥ 2 times (12.1% vs. 8.6%, P=0.249) and the incidence of replacing puncture site (10.7% vs. 6.4%, P=0.161). The next day after fetal reduction, color Doppler ultrasound was rechecked. In the intracranial injection group and intrathoracic injection group, the incidence of fetal heartbeat recovery [3.6% (8/224) vs. 1.1% (2/187), P=0.188], the volumes of KCl used [(2.6±1.0) mL vs. (2.8±1.1) mL, P=0.079], and the abortion rate within 4 weeks after fetal reduction (1.0% vs. 0.6%, P=0.654) were of no significant difference. In addition, there was no significant difference in the total abortion rate after fetal reduction, premature delivery rate, cesarean section rate, delivery gestational week and neonatal birth weight between the two groups (P>0.05). CONCLUSION Intracranial KCl injection can be an effective alternative to intrathoracic KCl injection for multifetal pregancy reduction.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 59:398-399. [PMID: 34182600 PMCID: PMC9724686 DOI: 10.1002/uog.23727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/15/2021] [Accepted: 06/17/2021] [Indexed: 06/13/2023]
Abstract
An asymptomatic 25-year-old G4P0120 with history significant for cervical insufficiency and classical cesarean delivery 12.5 months prior to conception underwent routine transabdominal ultrasound at 36w4d; umbilical cord was found to be protruding into a fluid-filled pouch extruding from the lower uterine segment. During emergent cesarean delivery, a full-thickness uterine rupture was confirmed; the fetal cranium and umbilical cord were extrauterine. Maternal genotype revealed greater than expected minor allele frequencies for several collagen genes. Maternal gene expression (mRNA) and corresponding microRNA expression of these collagen genes differed several-fold between her G3 (cervical insufficiency, classical cesarean delivery) and G4 (uterine rupture) pregnancies. This case highlights that (1) cervical insufficiency, poor myometrial wound healing, and uterine rupture may co-occur and pathophysiology may be related to collagen abnormalities and (2) asymptomatic uterine rupture can be detected sonographically, even in late pregnancy. Clinicians should remain vigilant for the possibility of uterine rupture, particularly among high-risk patients.

Abstract
OBJECTIVE To assess the risk for obstetric complications in women with congenital uterine anomalies and the risk in each main class of uterine anomaly (U2 [septate], U3 [bicorporeal], U4 [hemi-uterus]), based on the 2013 classification by the ESHRE (European Society of Human Reproduction and Embryology) and the ESGE (European Society for Gynaecological Endoscopy). DATA SOURCES MEDLINE, Scopus, and ClinicalTrials.gov were searched from inception until January 2021. The reference list of all included articles and previous systematic reviews were also screened to identify potential additional articles. METHODS OF STUDY SELECTION Comparative and noncomparative studies that investigated the obstetric outcomes of women with any type of known congenital uterine anomaly were considered eligible for inclusion. Screening and eligibility assessment was performed independently by two reviewers. TABULATION, INTEGRATION, AND RESULTS Forty-seven studies were included. The quality of included comparative studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. Odds ratios (ORs), pooled proportions of each obstetric outcome, and 95% CIs were calculated in RevMan and Stata accordingly, using random effects models. Congenital uterine anomalies were associated with increased risk of preterm birth (OR 3.89, 95% CI 3.11-4.88); cervical insufficiency (OR 15.13, 95% CI 11.74-19.50); prelabor rupture of membranes (OR 2.48, 95% CI 1.38-4.48); fetal malpresentation (OR 11.11, 95% CI 5.74-21.49); fetal growth restriction (OR 3.75, 95% CI 1.88-7.46); placental abruption (OR 5.21, 95% CI 3.34-8.13); placenta previa (OR 4.00, 95% CI 1.87-8.56); placental retention (OR 1.71, 95% CI 1.16-2.52); and cesarean birth (OR 4.52, 95% CI 2.19-9.31); when compared with those without anomalies. Pooled estimated risks were 25% for preterm birth, 40% for fetal malpresentation, 64% for cesarean birth, 12% for prelabor rupture of membranes, 15% for fetal growth restriction, 4% for placental abruption, 5% for preeclampsia, 13% for cervical insufficiency, and 2% for placenta previa. Classes U2 (septate), U3 (bicorporeal), and U4 (hemi-uterus) were also associated independently with preterm birth, fetal malpresentation, cesarean birth, and placental abruption. CONCLUSION Congenital uterine anomalies are associated with obstetric complications across all examined ESHRE and ESGE classifications. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42021244487.

Abstract
Congenital uterine anomalies (CUA) may influence reproductive performance, resulting in adverse pregnancy associated complications. This study aimed to assess the association of CUA subtypes with reproductive, obstetric, and perinatal outcomes. We performed a systematic search of the MEDLINE, EMBASE, and Cochrane libraries for studies comparing pregnancy outcomes between women with CUA and those with a normal uterus. The random effects model was used to estimate the odds ratios (ORs) with a 95% confidence interval (CI). Women with CUA had a lower rate of live births (OR 0.47; 95% CI 0.33-0.69), and a higher rate of first trimester miscarriage (OR, 1.79; 95% CI 1.34-2.4), second trimester miscarriage (OR 2.92; 95% CI 1.35-6.32), preterm birth (OR 2.98; 95% CI 2.43-3.65), malpresentation (OR 9.1; 95% CI 5.88-14.08), cesarean section (OR 2.87; 95% CI 1.56-5.26), and placental abruption (OR 3.12; 95% CI 1.58-6.18). Women with canalization defects appear to have the poorest reproductive performance during early pregnancy. However, unification defects were associated with obstetric and neonatal outcomes throughout the course of pregnancy. It may be beneficial for clinicians to advise on potential complications that may be increased depending on the type and severity of CUA.

The association of chronic endometritis with mid-trimester loss due to cervical incompetence and the outcome of laparoscopic cervical cerclage. Arch Gynecol Obstet 2021; 304:1345-1351. [PMID: 33811545 PMCID: PMC8019291 DOI: 10.1007/s00404-021-06029-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 03/12/2021] [Indexed: 11/04/2022]
Abstract
Purpose To examine the association of chronic endometritis (CE) with cervical incompetence (CI) in Chinese women with mid-trimester loss, and the impact of the presence of CE on the outcome of laparoscopic cervical cerclage (LCC).
Methods This retrospective cohort study included a study group of 293 women with mid-trimester loss due to CI (group I) and a comparison group of 332 women with recurrent first-trimester miscarriage (group II). Immunohistochemical study using CD138 epitope for the diagnosis of CE was completed in all subjects. Pre-conception LCC was undertaken in 247 women in the study group (group I). The study was approved by Institutional Review Board (IRB) (number 2015FXHEC-KY005). Results The prevalence of CE in group I was 42%, significantly (P < 0.001) higher than that of 23.5% in group II. Among 247 women in group I, there were no significant difference in mid-trimester loss rate, preterm delivery rate and term delivery rate in women with and without CE (2.2, 12.0, 85.8% vs. 1.8, 10.1, 88.1% respectively) and between women with CE treated and not treated with antibiotics prior to conception (2.3, 9.3, 88.4% vs. 2.0, 14.3, 83.7% respectively).
Conclusions Mid-trimester loss due to cervical incompetence is associated with chronic endometritis; However, the presence or not of CE and whether it was treated with antibiotics prior to conception did not appear to significantly influence the obstetric outcomes of women with CI after LCC.

Abstract
Despite the progress of medicine in the last decades, recurrent pregnancy loss, premature birth, and related complications are still a vast problem. The reasons for recurrent pregnancy loss and preterm delivery are diverse and multifactorial. One of the main reasons for these complications is cervical insufficiency, which means that the cervix is weak and unable to remain closed until the date of delivery. It manifests as painless softening and shortening of the cervix without contractions. The aim of the study was to review the available literature on rescue sutures, which are an emergency treatment in pregnancies with premature cervical dilatation and protrusion of the fetal membranes in the second trimester of pregnancy. This review confirms that emergency cerclage reduces the rate of preterm birth in patients with advanced cervical insufficiency. This procedure prolongs gestational age and improves the chances of survival of the newborn without increasing the risk of chorioamnionitis and preterm premature rupture of membranes.

The relationship between ovarian endometriosis and clinical pregnancy and abortion rate based on logistic regression model. Saudi J Biol Sci 2020; 27:561-566. [PMID: 31889882 PMCID: PMC6933232 DOI: 10.1016/j.sjbs.2019.11.021] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2019] [Revised: 11/13/2019] [Accepted: 11/18/2019] [Indexed: 12/01/2022] Open
Abstract
In order to study the relationship between ovarian endometriosis and clinical pregnancy, explore the correlation between endometriosis (EMT) and abortion rate and its mechanism, and provide a new theoretical basis for clinical diagnosis as well as treatment of endometriosis, in this study, pelvic endometriosis under 40 years old and have in vitro fertilization-embryo transfer (IVF-ET) operation will be selected as subjects of study. SPSS20.0 statistical software is used to analyze the data. When the measurement data between groups are compared, it is necessary to use t-test. It is necessary to use mean ± standard deviation (x¯±s) to expressed the results. When the counting data between groups is compared, it is necessary to use Chi-square test. Finally, the binomial classification logistic regression model is established by stepwise regression method to screen out the significant factors. The results show that the infertility duration of ovarian endometriosis cyst is (3.1 ± 1.9). The infertility years of other pelvic endometriosis are (3.9 ± 2.2). The infertility years of ovarian endometriosis cyst group are shorter than those of other pelvic endometriosis groups. Significant difference cannot be seen in follicle stimulating hormone (FSH) between the two groups of patients, and the basal FSH of other pelvic endometriosis groups is obviously lower in the two groups between the ages of 29 and 40 years. In the ovarian endometriotic cyst group, the significant difference can be seen (P < 0.05). Moreover, in the comparison of ovulation induction, the Gn dosage of fresh-cycle ovarian endometriosis patients is obviously higher than that of patients with ovarian endometriosis during the freezing cycle. The fertilization rate of patients with fresh cycle ovarian endometriosis is higher than that of patients with ovarian endometriosis during the freezing cycle. The two groups of patients with the factor of ovarian endometriosis after fresh embryo transplantation and the factor of fallopian tube are compared, and the abortion rate of the ovarian endometriosis group is lower than that of the fallopian tube group. Therefore, controlling the development of ovarian endometriosis can help to improve the pregnancy rate, reduce the abortion rate and improve the pregnancy outcome of patients with ovarian endometriosis.

Abstract
PURPOSE To evaluate the relationship between the uterine size measured by pelvic magnetic resonance and reproductive outcome in women with a unicornuate uterus. METHODS This was a retrospective study including 140 patients affiliated with unicornuate uterus diagnosed by the pelvic MR prior to their first pregnancy in the Obstetrics and Gynecology Hospital of Fudan University from April 2010 to December 2017. All the length of the unicornuate uterus were re-measured and recorded by skilled radiologists during the study period. We divided all the 140 participants with complete pelvic MR imaging into four groups by the best reproductive outcomes, which refers to Group 1 (primary infertility, n = 21), Group 2 ( < 24 weeks' gestation, n = 34), Group 3 (preterm delivery, 24-35 weeks' gestation, n = 13), Group 4 ( ≥ 35 weeks' gestation, n = 72), followed them up and then analyzed the data. RESULTS Measurements of 140 patients with hemi-uteri were retrieved for analysis. The mean length of the uterine was 4.90 ± 0.56 cm. There were no significant differences in the uterine cavity length, cervical length, endometrial thickness and uterine wall thickness between the four groups while the uterine length (P = 0.001) was statistically significant. Women with uterine lengths ≥ 4.5 cm were more likely to experience full-term delivery compared with the other group (P = 0.001). Ordinal multiple logistic regression analysis showed that the uterine length [OR = 9.03 (95% CI: 2.90-28.13)] and uterine cavity length [OR = 0.32 (95% CI: 0.06-2.04)] were independent protective factors for better obstetric outcomes CONCLUSION: The uterine length is a reliable prognostic factor for the gestational week of delivery and an appropriate antenatal surveillance factor of women with unicornuate uterus.

Abstract
Objectives: To evaluate the safety and effectiveness of late cervical cerclage performed beyond 17 weeks of gestation. The outcomes of interest were effectiveness of late cerclage in prolongation of pregnancy and evaluation of pregnancy outcome including maternal and fetal complications. Study design: A total of 30 patients underwent late cervical cerclage during the study period. Of them, two were twin pregnancies. A late cerclage was performed after the diagnosis of cervical shortening or dilatation in 20 patients. We performed a retrospective case series review. One case was lost to follow up (delivery in another medical center). Medical information was retrieved from all cases of patients who underwent a late cervical cerclage between the years 2010 and 2016 at the Soroka University Medical Center, a tertiary medical center. Continuous variables were expressed as mean ± standard deviation. Categorical variables were expressed as proportions. Results: The average gestational age at birth was 35 ± 5.1 weeks of gestation. The mean interval between cerclage and delivery in the study population was 17 ± 5.62 weeks. Nine cases (32.1%) resulted in preterm deliveries, three of them below 34 weeks of gestation (one twin pregnancy and two pregnancies diagnosed with cervical dilation prior to cerclage). Among all the preterm deliveries, there were four cases of preterm prelabor rupture of membranes (13.3%). Of the 28 deliveries, 24 women (85.7%) had a vaginal delivery, while four women (14.3%) underwent a cesarean section. No cases of cervical tear were described. The cerclage was sent to bacteriology after removal, showing positive cultures for Candida species in nine cases (31%). Conclusions: In our study population, late cervical cerclage was found to be a safe procedure resulting in almost 90% of successful vaginal deliveries without maternal or fetal complications. This procedure might be effective in the prolongation of pregnancy in women with cervical dynamics in the late second trimester.
