Subsequent pregnancy outcomes and fertility rates in the case series that underwent bilateral hypogastric artery ligation(BHGAL)due to severe postpartum hemorrhage

Objective:To evaluate the effect of bilateral hypogastric artery ligation(BHGAL)on women's pregnancy outcomes and fertility rates in cases with severe postpartum hemorrhage.Methods:Patients hospitalized in a tertiary care center between 2007 and 2018 were included in the study.The records of cases were obtained from the hospital database,retrospectively.Maternal demographic data,morbidities or complications associated with BHGAL surgery,any additional haemostatic interventional or surgical procedures,preoperative admission and lowest postoperative haematocrit-hemoglobin values,blood products given,type of anaesthesia,intensive care unit(ICU)and length of hospital stay were recorded.In cases without surgical sterilization,future fertility and subsequent pregnancy outcomes were assessed for at least two years after operation.Information was obtained through face-to-face or telephone interviews with patients whose long-term fertility and subsequent pregnancy outcomes were assessed.Results:Sixty-eight patients with BHGAL surgery history were included in the study.26 Of 37 cases(70%)that did not undergo surgical sterilization had a desire for pregnancy after the surgery.Six of these cases(23%)were diagnosed with secondary infertility.The fertility rate of these cases was 77%,and subsequent pregnancy was detected in 20 women.A total of 25 pregnancies,including first and second pregnancies,developed,and 15 of these pregnancies resulted in term delivery,six preterm births,one stillbirth,and three abortions.Conclusions:The postoperative pregnancy rate was found to be higher than the rate of women with infertility problems,and this surgery does not seem to adversely affect pregnancy outcomes.This is a tertiary center experience and cohort studies with large patient series are needed.

Predictors of Adverse Pregnancy Outcomes Following Traumatic Injuries

Objective After traumatic injury in pregnant women,providing timely and appropriate management for high-risk patients is crucial for both pregnant women and fetuses.This study aimed to identify risk factors that predict adverse pregnancy outcomes after traumatic injury.Methods A retrospective cohort study including 317 pregnant patients who experienced trauma was conducted.The collected data included general demographics,injury mechanisms and adverse pregnancy outcomes.Patients were divided into two subgroups based on the absence or presence of trauma-related adverse pregnancy outcomes.Univariate and multivariate logistic regressions were conducted to estimate the associations between clinical variables and adverse pregnancy outcomes.Results A total of 41(12.93%)patients experienced adverse pregnancy outcomes within the first 24 h post-trauma.This study revealed that age>35 years(OR=14.995,95%CI:5.024–44.755,P<0.001),third trimester trauma(OR=3.878,95%CI:1.343–11.204,P=0.012),abdominal pain(OR=3.032,95%CI:1.221–7.527,P=0.017),vaginal bleeding(OR=3.226,95%CI:1.093–9.523,P=0.034),positive scan in focused assessment with sonography for trauma(FAST)positive(OR=8.496,95%CI:2.825–25.555,P<0.001),9≤injury severity score(ISS)<16(OR=3.039,95%CI:1.046–8.835,P=0.041)and ISS≥16(OR=5.553,95%CI:1.387–22.225,P=0.015)increased the probability of posttraumatic adverse pregnancy outcomes.Maternal age,gestational age at delivery,vaginal bleeding and positive FAST results were risk factors for abnormal delivery.Conclusion Advanced maternal age,third trimester,and positive FAST results should alert multidisciplinary trauma teams to closely monitor patients to prevent adverse pregnancy outcomes.

Clinical validation of the early embryo viability assessment system: Analysis for the blastocyst morphology and pregnancy outcomes

Objective:To determine the relationship between the early embryo viability assessment(EEVA)and blastocyst morphological parameters and pregnancy outcomes.Methods:This retrospective cohort study was conducted on 291 intracytoplasmic sperm injection cycles including 2522 embryos with indications of prolonging embryo culture to the blastocyst stage in the Genea embryo review incubator,and 511 single vitrified-warmed blastocyst transfer cycles from January 2020 to June 2023.The EEVA system produced an EEVA score from E1(best)to E5(worse)for the potential of blastocyst formation.Blastocyst morphology was evaluated.The association between the EEVA score and each type of blastocyst morphology,implantation rate,clinical pregnancy,and ongoing pregnancy were assessed using generalized estimating equations.Results:The inner cell mass A(ICM A),trophectoderm A(TE A),blastocoele expansion degree of 3,4,5,6,7 rates were higher with lower the EEVA score.The adjusted odd ratio(aOR)(E5 vs E1)was 0.3 for ICM A,0.174 for TE A and 0.210 for BL3,4,5,6,7(all P<0.001),suggesting a significant association between lower EEVA scores and improved embryo quality.The implantation,clinical pregnancy,and ongoing pregnancy rate were also higher with lower the EEVA score.The aOR of E5 vs E1 was 0.245 for implantation,0.185 for clinical pregnancy and 0.200 for ongoing pregnancy rate(P<0.001).Conclusions:There were associations between blastocyst morphology,pregnancy outcome and EEVA scores.The good blastocyst morphology and pregnancy outcomes are higher with lower the EEVA score.

Adverse Pregnancy Outcomes Following Cryotherapy, Thermal Ablation and Loop Electrosurgical Excision Procedure for Cervical Intraepithelial Neoplasia Treatment: A Pilot Study among Zambian Women

Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.

Comparative effects of insulin pump and injection on gestational diabetes mellitus pregnancy outcomes and serum biomarkers

BACKGROUND Insulin injection is the basic daily drug treatment for diabetic patients.AIM To evaluate the comparative impacts of continuous subcutaneous insulin infusion(CSII).METHODS Based on the treatment modality received,the patients were allocated into two cohorts:The CSII group and the multiple daily injections(MDI)group,with each cohort comprising 210 patients.Comparative assessments were made regarding serum levels of serum-secreted frizzled-related protein 5,homocysteine,and C1q/TNF-related protein 9.Furthermore,outcomes such as fasting plasma glucose,2-hour postprandial glucose levels,pain assessment scores,and the incidence of complications were evaluated post-treatment.RESULTS The CSII group displayed notably lower fasting plasma glucose and 2-h postprandial glucose levels in comparison to the MDI group(P<0.05).Subsequent analysis post-treatment unveiled a significantly higher percentage of patients reporting no pain in the CSII group(60.00%)in contrast to the MDI group(36.19%)(P<0.05).Additionally,the CSII group exhibited a markedly reduced occurrence of fetal distress and premature rupture of membranes compared to the MDI group(P<0.05).However,there were no significant variances observed in other pregnancy outcomes between the two groups(P>0.05).A statistical analysis revealed a significant difference in the incidence of complications between the groups(χ^(2)=11.631,P=0.001).CONCLUSION The utilization of CSII via an insulin pump,as opposed to MDI,can significantly enhance the management of insulin administration in patients with GDM by diversifying the sites of insulin delivery.This approach not only promotes optimal glycemic control but also regulates metabolic factors linked to blood sugar,reducing the likelihood of adverse pregnancy outcomes and complications.The clinical relevance and importance of CSII in GDM management highlight its wide-ranging clinical usefulness.

Analysis of Cardiac Functional Status and Factors Influencing Adverse Pregnancy Outcomes in Pregnant Women with Combined Heart Disease

Objective:To investigate the cardiac function of pregnant women with complicated heart disease during pregnancy and the factors influencing the adverse pregnancy outcome.Methods:A total of 162 cases of pregnant women with complicated heart disease admitted to the Beijing Anzhen Hospital from October 2021 to December 2023 were selected to compare the occurrence of adverse pregnancy outcomes in pregnant women with complicated heart disease at different levels of cardiac function and to analyze the single and multi factors leading to adverse pregnancy outcomes in pregnant women with complicated heart disease.Results:Among 162 pregnant women with combined heart disease in pregnancy,the highest percentage of heart disease type was congenital heart disease(80/49.38%),and the lowest percentage was other(9/5.56%);the overall incidence of adverse pregnancy outcomes in pregnant women with combined heart disease in pregnancy with cardiac function grades of 3–4 cardiac function(30/68.18%)was higher than that in pregnant women with combined heart disease in cardiac function grades of 1–2(40/33.90%)(P=0.000);age,marital status,hypertension,and past history of all pregnant women were not statistically significant(P>0.05);gestational age,type of heart disease,and cardiac function grading were statistically significant(P<0.05),and these factors were all independent risk factors for adverse pregnancy resolution in pregnant women with combined heart disease(P<0.05).Conclusion:The overall incidence of adverse pregnancy outcomes was higher in pregnant women with heart disease than in those with heart disease grades 1–2,and the number of pregnancies,the type of heart disease,and heart function grades were all independent risk factors for adverse pregnancy outcomes in pregnant women with heart disease.

A Study on the Correlation of Body Mass Management During Pregnancy with Adverse Pregnancy Outcomes and Labor Progression

Objective:To investigate the effects of body mass management during pregnancy on adverse pregnancy outcomes,duration of labor,and neonatal birth weight.Methods:472 pregnant women who visited Beijing Anzhen Hospital from January to December 2023 were selected,and the pregnant women were divided into 236 each in the observation group and the control group.Body mass of pregnant women was measured and BMI was calculated in early and late pregnancy respectively,and the pregnant women in the control group were guided by routine management,while the observation group was guided by body mass management during pregnancy.The growth of maternal body mass,mode of delivery,postpartum hemorrhage,neonatal score,neonatal blood glucose at birth,and umbilical artery blood,as well as the comparison of the duration of labor,were observed.Results:The observation group was significantly better than the control group in terms of mode of delivery,postpartum hemorrhage,and body mass growth,with statistically significant differences(P<0.05),and there was no statistical significance in terms of neonatal scores,neonatal blood glucose at birth,and umbilical artery blood(P>0.05);the time of the first stage of labor and the time of the second stage of labor of the mothers in the observation group was significantly better than that of the control group,with statistical differences(P<0.05),and the time of the third stage of labor of the mothers in the observation group was statistically better than that of the control group.There was no statistically significant difference between the time of the third stage of labor in the observation group and the control group(P>0.05),and the time of the total stage of labor in the observation group was statistically better than that in the control group(P<0.05).Conclusion:Body mass management during pregnancy can effectively improve maternal control of weight gain,reduce labor time,and decrease the occurrence of adverse pregnancy outcomes.

A Meta-Analysis on the Correlation Between Herpes Simplex Virus Type II Infection and Adverse Pregnancy Outcomes in China

Objective:To systematically evaluate the relationship between herpes simplex virus type II(HSV-2)infection in pregnant women and the adverse pregnancy outcomes(preterm delivery,spontaneous abortion,stillbirth,monstrum,low birth weight,intrauterine growth retardation,premature rupture of membranes),so as to provide clinical guidance for the prevention and treatment of adverse pregnancy outcomes caused by HSV-2 infection in pregnant women.Methods:2140 articles were collected from PubMed,China National Knowledge Infrastructure(CNKI),and other databases for the past 20 years.According to the inclusion criteria,the literatures about the relationship between HSV-2 infection of pregnant women and adverse pregnancy outcomes were screened.The effect model was determined by heterogeneity test results,and the meta-analysis was carried out by RevMan 5.3 software.Results:The results of meta-analysis showed that the positive rate of HSV-2 was higher in the adverse pregnancy group than in the control group(odds ratio[OR]:7.92,95%confidence interval[Cl]:3.91-16.01),and the difference was statistically significant.Conclusion:HSV-2 infection will increase the risk of adverse pregnancy outcomes.Prevention and effective control of HSV-2 infection in early pregnancy can reduce the rate of adverse pregnancy outcome,which is of great significance to the promotion of eugenics.

Effect of Internet+continuous midwifery service model on psychological mood and pregnancy outcomes for women with highrisk pregnancies

BACKGROUND There are many drawbacks to the traditional midwifery service management model,which can no longer meet the needs of the new era.The Internet+continuous midwifery service management model extends maternal management from prenatal to postpartum,in-hospital to out-of-hospital,and offline to online,thereby improving maternal and infant outcomes.Applying the Internet+continuous midwifery service management model to manage women with highrisk pregnancies(HRP)can improve their psycho-emotional opinion and,in turn,minimize the risk of adverse maternal and/or fetal outcomes.AIM To explore the effectiveness of a midwife-led Internet+continuous midwifery service model for women with HRP.METHODS We retrospectively analyzed the clinical data of 439 women with HRP who underwent prenatal examination and delivered at Shanghai Sixth People's Hospital(affiliated to the Shanghai Jiao Tong University School of Medicine)from April to December 2022.Among them,239 pregnant women underwent routine obstetric management,and 200 pregnant women underwent Internet+continuous midwifery service mode management.We used the State-Trait Anxiety Inventory,Edinburgh Postnatal Depression Scale,and analysis of delivery outcomes to compare psychological mood and the incidence of adverse delivery outcomes between the two groups.RESULTS The data showed that in early pregnancy,the anxiety and depression levels of the two groups were similar;the levels gradually decreased as pregnancy progressed,and the decrease in the continuous group was more significant[31.00(29.00,34.00)vs 34.00(32.00,37.00),8.00(6.00,9.00)vs 12.00(10.00,13.00),P<0.05].The maternal self-efficacy level and strategy for weight gain management were better in the continuous group than in the traditional group,and the effective rate of midwifery service intervention in the continuous group was significantly higher than in the control group[267.50(242.25,284.75)vs 256.00(233.00,278.00),74.00(69.00,78.00)vs 71.00(63.00,78.00),P<0.05].The incidence of adverse delivery outcomes in pregnant women and newborns and fear of maternal childbirth were lower in the continuous group than in the traditional group,and nursing satisfaction was higher[10.50%vs 18.83%,8.50%vs 15.90%,24.00%vs 42.68%,89.50%vs 76.15%,P<0.05].CONCLUSION The Internet+continuous midwifery service model promotes innovation through integration and is of great significance for improving and promoting maternal and child health in HRP.

Effect of polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine on pregnancy outcomes in intrahepatic cholestasis

BACKGROUND Intrahepatic cholestasis of pregnancy(ICP)is a liver disorder that occurs in pregnant women and can lead to a range of adverse pregnancy outcomes.The condition is typically marked by pruritus(itching)and elevated levels of liver enzymes and bile acids.The standard treatment for ICP has generally been ursodeoxycholic acid and ademetionine 1,4-butanedisulfonate,but the efficacy of this approach remains less than optimal.Recently,polyene phosphatidylcholine has emerged as a promising new therapeutic agent for ICP due to its potential hepatoprotective effects.AIM To evaluate the effect of polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate on bile acid levels,liver enzyme indices,and pregnancy outcomes in patients with ICP.METHODS From June 2020 to June 2021,600 patients with ICP who were diagnosed and treated at our hospital were recruited and assigned at a ratio of 1:1 via randomnumber table method to receive either ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate(control group,n=300)or polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate(combined group,n=300).Outcome measures included bile acids levels,liver enzyme indices,and pregnancy outcomes.RESULTS Prior to treatment,no significant differences were observed between the two groups(P>0.05).Post-treatment,patients in both groups had significantly lower pruritus scores,but the triple-drug combination group had lower scores than the dual-drug combination group(P<0.05).The bile acid levels decreased significantly in both groups,but the decrease was more significant in the triple-drug group(P<0.05).The triple-drug group also exhibited a greater reduction in the levels of certain liver enzymes and a lower incidence of adverse pregnancy outcomes compared to the dual-drug group(P<0.05).CONCLUSION Polyene phosphatidylcholine/ursodeoxycholic acid/ademetionine 1,4-butanedisulfonate effectively relieves pruritus and reduces bile acid levels and liver enzyme indices in patients with ICP,providing a positive impact on pregnancy outcome and a high safety profile.Further clinical trials are required prior to clinical application.

Impact of maternal HBsAg carrier status on pregnancy outcomes in Duhok city, Iraq

Objective: To investigate the relationship between hepatitis B virus(HBV) positivity and pregnancy outcomes. Also, the association between HBV-related risk factors and HBV status was studied.Methods: A total of 100 HBV positive pregnant women were recruited and the pregnancy outcomes were compared with 301 HBV negative women. Blood samples were collected and tested for HBV by HBs Ag ELISA. Data were collected for recruited subjects using interview questionnaire.Results: Data analysis showed that 51/100(51%) of the HBV-positive subjects gave a history of HBV in the family which was significantly higher than that of HBV-negative patients [41/301(13.6%) P = 0.001]. A significant association was found between positive history of surgery and HBs Ag positivity(P = 0.009). Then, pregnancy outcomes were stratified according to the HBV positivity. No significant association was found between HBV status and pregnancy outcomes(P > 0.05 for all).Conclusions: Positive family history of HBV and previous surgical procedures are associated with higher rate of HBV positivity. No association is found between HBV positivity and pregnancy outcomes.

Pregnancy Outcomes of Repeat Cesarean Section in Peking Union Medical College Hospital

Objective To evaluate the effect of elective repeat cesarean section on the maternal and neonatal outcomes. Methods A retrospective clinic- and hospital-based survey was designed for comparing the maternal and neonatal outcomes of elective repeat cesarean section [RCS group （one previous cesarean section） and MRCS group （two or more previous cesarean sections）] and primary cesarean section （FCS group） at Peking Union Medical College Hospital from January 1998 to December 2007. Results The incidence of repeat cesarean section increased from 1.26% to 7.32%. The mean gestational age at delivery in RCS group （38.1±1.8 weeks） and MRCS group （37.3±2.5 weeks） were significantly shorter than that in FCS group （38.9±2.1 weeks, all P〈0.01）. The incidence of complication was 33.8% and 33.3% in RCS group and MRCS group respectively, and was significantly higher than that in FCS group （7.9%, P〈0.05）. Dense adhesion （13.5% vs. 0.4%, OR=7.156, 95% CI： 1.7-30.7, P〈0.01） and uterine rupture （1.0% vs. O,P〈0.05） were commoner in RCS group compared with FCS group. Neonatal morbidity was similar among three groups （P〉0.05）. Conclusions Repeat cesarean section is associated with more complicated surgery technique and increased frequency of maternal morbidity. However, the incidence of neonatal morbidity is similar to primary cesarean section.

Knowledge, Attitude and Practice of Adverse Pregnancy Outcomes Prevention among Women of Reproductive Age in Nasarawa Local Government Area, Kano State, Nigeria

Background: Adverse pregnancy outcomes continue to contribute substantially to maternal mortality as well as poor maternal and fetal health outcomes whose burden can be reduced by the initiation of preventive behaviors like the uptake of maternal health services. This continuous unacceptably high maternal mortality justifies a need for progressive research to better understand the predictors of the preventive behaviors of women towards adverse pregnancy outcomes. This study was conducted to assess levels of knowledge, attitudes about adverse pregnancy outcomes and preventive practices among women of reproductive age in Nassarawa local government area, Kano State, Nigeria. Methodology: The study was a cross-sectional descriptive study that employed a four-sectioned pretested researcher administered questionnaire to collect data on knowledge, attitude and practice of adverse pregnancy outcomes prevention among 164 consenting respondents in Kano State, Nigeria between November 2020 and December 2020. Responses were transformed and computed using SPSS version 26 to generate descriptive statistics. Regression analysis was done to test the degree of association between the predictors and practice of adverse pregnancy outcomes prevention with the level of significance set at a cut-off of p ≤ 0.05. Results: The findings showed that the majority of the respondents were between 20 - 24 years of age and had secondary educational attainment. Results further revealed that knowledge and attitude about adverse pregnancy outcomes which were both measured on 18-point scales, reported for the respondents’ mean scores of 9.46 (9.07 ± 9.85) and 10.72 (9.79 ± 10.62) respectively. The practice of adverse pregnancy outcomes prevention when assessed on a 15-point scale shows that respondents scored a mean of 7.42 ± 8.30 which denotes 53.4% of the level of prevention practice anticipated from the respondents. The study also showed a significant positive association between the level of knowledge (p = 0.010), attitude (p < 0.001) and prevention practice of adverse pregnancy outcomes. Conclusions: The findings reported an average but inadequate knowledge and neutral attitude that predicted unsatisfactory adverse pregnancy outcomes prevention practices among the examined reproductive-aged women, which calls for targeted health education on adverse pregnancy outcomes within the community in order to inform better prevention practices.

Exploring the Relationship between Obstetrical Nurses’ Work and Pregnancy Outcomes

The Registered Nurses Association of Ontario Healthy Work Environments Best Practice Guideline recommends that employers promote safe, healthy workplaces. Healthy workplaces include addressing the unique needs of nurses who work while pregnant. The purpose of this descriptive study, summarizing information from 120 pregnancies reported by 95 nurses, was to determine if the workload of obstetrical nurses was associated with negative pregnancy outcomes, including preterm delivery and birth weight. Full-time obstetrical nursing work is a predictor of reduced birth weight, but not of preterm birth when compared to outcomes of obstetrical nurses working part time. One third of nurses reported pregnancy complications and most nurses experienced work-related and personal stress. Further research evaluating work modifications during pregnancy is indicated to improve birth outcomes.

Serum β-hCG level on day 7 of frozen-thawed embryo transfer: association with the clinical pregnancy outcomes in artificial cycles

Objective:The relationship between serum beta human chorionic gonadotropin(β-hCG)levels of patients(7 days after the transplantation of frozen-thawed embryos)and the pregnancy outcomes was investigated.Methods:This study was designed as a retrospective clinical trial of 366 women who underwent frozen-thawed embryo transfers(FETs)in artificial cycles.Patients were divided into three groups:clinical pregnancy group,biochemical pregnancy group,and non-pregnant group according to their pregnancy outcomes.Serumβ-hCG levels were tested on day 4,7,9,11 and 14 after FET.Results:In the clinical pregnancy group,the serumβ-hCG levels after 7-day post-transplantation were significantly elevated(16.20 IU/L vs.3.07 vs.0.1 IU/L;P<0.05)compared with the other two groups.Furthermore,it was found that Area Under Curve(AUC=0.96)was significant with cut-off value higher than 4.26 IU/L(sensitivity=92.3%,specificity=90.2%)to predict the clinical pregnancy outcomes in the receiver operating characteristic(ROC)analysis ofβ-hCG concentrations on day 7 of post-transplantation.Conclusion:Our results suggested that the elevated serumβ-hCG levels on day 7 of post-transplantation could predict the positive clinical pregnancy outcomes in artificial FET cycles.

The cervical function and pregnancy outcomes after hysteroscopic resection of the complete uterine septum,duplicate cervix and vaginal septum

Objective:To evaluate cervical function and pregnancy outcomes after hysteroscopic resection of the complete uterine septum,duplicate cervix and vaginal septum with Metzenbaum scissors.Methods:Between January 2010 and December 2016,13 patients admitted to the Department of Obstetrics and Gynecology of Sir Run Run Shaw Hospital with complete uterine septum,duplicate cervix and vaginal septum,were enrolled into this study.The cervical and corporal septum was cut by Metzenbaum scissors,and residual septum was cut by micro scissors under hysteroscopy.The vaginal septum was cut with the unipolar electric knife.Results:The operation time was about 10±1.31 min.All the 13 patients present normal uterine cavities without scar formation under hysteroscopy at 3 months after operation,there was mild adhesions between anterior and posterior intrauterine wall on 2 cases.After operation,there were 13 pregnancies naturally conceived in 11 patients,10 deliveries.The live birth rate was 76.92%,the early miscarriage rate was 23.08%.The cesarean section ratewas 30%,the vaginal delivery ratewas 70%,and all were term births.Conclusion:The operation was simple,convenient,and fast,without any complications and cervical insufficiency.It was easy to have vaginal deliveries.

Risk Factors and Pregnancy Outcomes： Complete versus Incomplete Placenta Previa in Mid-pregnancy

This prospective study was conducted to compare risk factors and pregnancy outcomes between women with complete placenta previa and those with incomplete placenta previa diagnosed in mid-pregnancy. The study was carried out from April 2014 to December 2015, during which 70 patients with complete previa and 113 with incomplete previa between 20＋0 weeks and 25＋6 weeks of gestation were included. Maternal demographics and pregnancy outcomes were compared between the two groups. Comparisons between categorical variables were tested by chi-squared test and those between continuous variables by Student t test. Resolution ofprevia occurred in 87.43% of the studied women. The mean gestational age at resolution was 32.1＋4.4 weeks. Incidence of maternal age ≥35 years and incidence of prior uterine operation 〉3 were high in women with complete previa （28.6% vs. 8.8%, P=0.003; 28.6% vs. 8.8%, P=0.003）. Resolution ofprevia occurred less often in complete previa group （74.3% vs. 95.6%, P=0.001）. Women with complete previa admitted earlier （37.3±2.0 weeks vs. 38.1±1.4 weeks, P=0.011） and delivered earlier （37.7±1.2 weeks vs. 38.3±1.4 weeks, P=0.025）. Maternal age ≥35 years and prior uterine operation 〉3 increase the risk of complete previa in mid-pregnancy. Placenta previa is more likely to persist in women with complete previa than those with incomplete previa diagnosed in mid- pregnancy. What is more, women with complete previa in mid-pregnancy delivers earlier.

Untreated Prior Pulmonary Tuberculosis Adversely Affects Pregnancy Outcomes in Infertile Women Undergoing in vitro Fertilization and Embryo Transfer: A Large Retrospective Cohort Study

Objective Prior pulmonary tuberculosis(PTB) on chest X-ray(CXR) was commonly found in infertile patients receiving examinations before in vitro fertilization and embryo transfer(IVF-ET). It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.

Influence of Blastocysts Morphological Score on Pregnancy Outcomes in Frozen-thawed Blastocyst Transfers: a Retrospective Study of 741 Cycles

The influence of inner cell mass （ICM） and trophectoderm （TE） score on pregnancy out- comes in frozen-thawed blastocyst transfer cycles was analyzed. A retrospective analysis of 741 cycles of frozen-thawed blastosysts transfer was performed. All cycles were divided into four groups based on the number and morphological score of blastocysts： S-ICM B/TE B group （n=91）, the single blastocyst transfer oflCM B and TE B; D-ICM B/TE B group （n=579）, double blastocysts transfer oflCM B/TE B; D-1CM B/TE C group （n=35）, double blastocysts transfer of ICM B/TE C; and D-ICM C/TE B group （n=36）, double blastocysts transfer ofTE B/ICM C. The pregnancy outcomes were compared among the four groups. As compared with D-ICM B/TE C group, the clinical pregnancy rate, implantation rate and multiple pregnancy rate were increased in D-ICM B/TE B group （74.96% vs. 57.14%, 57.43% vs. 37.14%, and .48.62% vs. 25%, respectively, P〈0.05 for all）. Clinical pregnancy rate and implantation rate in D-ICM B/TE B group were also higher than in D-ICM C/TE B group （74.96% vs. 50%, and 57.43% vs. 33.33%, both P〈0.05）. Multivariable Logistic regression analysis indicated that ICM score was a better predictive parameter for clinical pregnancy （OR=3.05, CI 1.70-5.46, P〈0.001）, while the trophectoderm score was a better one for early abortion （OR=0.074, CI 0.03-0.19, P〈0.001）. Clinical pregnancy rate and multiple pregnancy rate in S-ICM B/TE B group were significantly lower than those in D-ICM B/TE B group （46.15% vs. 74.96%, and 2.38% vs. 48.62%, both P〈0.05）, but there was no si~,,niflcant difference in the implantation rate between the two groups. It was suggested that the higher score of ICM and TE may be indicative of the better pregnancy outcomes. The ICM score is a better predictor of clinical pregnancy than TE, while TE score is a better one in predicting early abortion. Sin- gle ICM B/TE B blastocyst transfer in frozen-thawed cycles can also get satisfactory pregnancy out- comes.

Pregnancy Outcomes Following Transvaginal Cerclage for Cervical Insufficiency：Results From a Single-center Retrospective Study

To study maternal and perinatal outcomes after cervical cerclage in both singleton and twin pregnancies,we retrospectively reviewed women undergoing cervical cerclage for cervical insufficiency at Tongji Hospital,Wuhan,China from January 1,2010 to July 31,2015 to evaluate primary and secondary outcomes for subgroups with cervical length（CL） ≤15,〉15 to 〈25,and ≥25 mm.Of 166 patients who underwent cervical cerclage,after exclusion of patients with missed abortion and continuing pregnancy,141 patients（121 singleton and 20 twin pregnancies） were included in the analysis.Mean gestational age at birth was 34.22 and 28.27 weeks for singleton and twin pregnancies,respectively.There were 17（14.05%） and 13（33.33%） neonatal deaths in singleton and twin pregnancies,respectively.Mean age（31.60±4.62 vs.31.22±4.63 years,P=0.39） and gestational weeks at cerclage（18.50±4.62 vs.19.31±4.99,P=0.47） were similar for both groups.Mean gestational weeks at delivery（34.22±5.77 vs.28.27±6.17,P〈0.001） and the suture to delivery interval（15.72±7.15 vs.8.96±6.70,P〈0.001） were significantly longer in the singleton group.These variables indicate a linear negative correlation with the degree of CL shortening,with better outcomes in patients with CL ≥25 mm who underwent cerclage,both in singleton and twin pregnancies.No difference in mode of delivery existed between the singleton group and twin group.Our results indicate a high risk of preterm delivery in both groups,especially in the twin group.Patients with a history of preterm labor and CL 〉25 mm in the current pregnancy,possibly in a twin pregnancy,could benefit from elective cervical cerclage;however,cervical cerclage was inadvisable for twin pregnancies with a CL 〉15 and 〈25 mm.Our data emphasize the importance of re-evaluating the efficacy of cervical cerclage for twin pregnancies in well-designed clinical trials.
