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.

Impact of uterine artery embolization on ovarian function and pregnancy outcome after uterine-fibroids treatment:A prospective study

Uterine fibroids are benign tumors that originate from smooth muscle cells of the uterus.It is the most common gynecological disorder,affecting up to 80%of women of reproductive age.Uterine fibroids can cause various symptoms such as abnormal uterine bleeding,pelvic pain,infertility,and pregnancy complications.The treatment options for uterine fibroids include medical therapy,surgical intervention,and minimally invasive techniques.AIM To compare ovarian function of women with uterine fibroids who did or did not undergo uterine artery embolization(UAE).METHODS This prospective cohort study enrolled 87 women with symptomatic uterine fibroids who underwent UAE,and 87 women with the same symptoms who did not undergo UAE but received conservative management or other treatments.The two groups were matched for age,body mass index,parity,and baseline characteristics of uterine fibroids.The primary outcome was ovarian function that was evaluated by serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),and anti-Müllerian hormone(AMH),as well as ovarian reserve tests,such as antral follicle count(AFC)and ovarian volume(OV).The secondary outcome was fertility that was evaluated based on the menstrual cycle,ovulation,conception,pregnancy,and delivery.The participants were followed-up for 36 months and assessed at 1,3,6,12,24,and 36 months after treatment.RESULTS The study found that the most common minor complication of UAE was postembolization syndrome in 73.6% of women,resolving within a week.No significant differences were observed between the UAE group and the control group in serum levels of reproductive hormones(FSH,LH,E2,AMH)and ovarian reserve indicators(AFC,OV)at any point up to 36 months post-treatment.Additionally,there were no significant differences in conception,pregnancy,or delivery rates,with the average time to conception and gestational age at delivery being similar between the two groups.Birth weights were also comparable.Finally,there was no significant correlation between ovarian function,fertility indicators,and the type or amount of embolic agent used or the change in fibroids posttreatment.CONCLUSION UAE resulted in significantly positive pregnancy outcomes,no adverse events post-treatment,and is a safe and effective treatment for uterine fibroids that preserves ovarian function and fertility.

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.

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.

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.

Normal pregnancy outcome after first-trimester exposure to semaglutide in an overweight woman: a case report

We reported a case of an overweight 34-year-old woman who unexpectedly became pregnant while undergoing semaglutide in early pregnancy and delivered a healthy male infant by caesarean section at 37 weeks and 4 days of gestation.Until now,the safety of semaglutide for use during pregnancy was unknown.This report may contribute to the limited knowledge available on pregnant women exposure to semaglutide.

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.

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.

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.

Preservation of sperm of cancer patients： extent of use and pregnancy outcome in a tertiary infertility center

Sperm cryopreservation is the best modality to ensure future fertility for males diagnosed with cancer. The extent to which cryopreserved sperm is actually used for impregnation, the fertility treatment options that are available and the success rates of these treatments have not been investigated in depth. The medical records of 682 patients who cryopreserved sperm cells due to cancer treatment were analyzed. Seventy of these patients withdrew their frozen sperm for fertility treatments over a 20-year period （most within the first 4 years after cryopreservation）. Sperm quality of different malignancies and outcomes of assisted reproduction treatment （ART） for pregnancy achievement in relation to the type of treatment and the type of malignancy were evaluated. The results showed that the rate of using cryo-thawed sperm from cancer patients for fertility treatments in our unit was 10.3%. Sperm quality indices differed between different types of malignancies, with the poorest quality measured in testicular cancer. Conception was achieved in 46 of the 184 ART cycles （25%）, and resulted in 36 deliveries. The use of intracytoplasmic sperm injection （ICSI） methodology yielded a significantly higher pregnancy rate （37.4%） than intrauterine insemination （IUI; 11.5%） and was similar to other groups of infertile couples using these modalities. In vitro fertilization （IVF） failed to produce pregnancies. In conclusion, the rate of use of cryopresseved sperm in cancer patients is relatively low （10.3%）. Achievement of pregnancies by ICSI presents the best option but when there are enough stored sperm samples and adequate quality, I UI can be employed. Cryopreservation is nevertheless the best option to preserve future fertility potential and hope for cancer patients.

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.

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.

Zinc and Copper Status in Urban Thai PregnantWomen and Their Pregnancy Outcome

Zinc and copper intakes and serum concentrations were determined at the 32th and 36th week of pregnancy in 96 healthy Thai women attending a prenatal clinic. Dietary data from 3-day food records revealed that the mean dietary zinc and copper intakes in Thai pregnant women were 6. 9 and 1. 7mg/d (equivalent to 34 and 69% of Thai RDA), respectively. Fifty-five percent of zinc intake was from animal origin, whereas 59% of copper intake was from plant origin.The infants of the 64 women who were in the study until delivery, were all normal.Most (>96%) of the maternal serum zinc and copper concentrations were within normal ranges. Only one woman at 32th week had low serum zinc level (<6. 4μmol/L). There were no significant correlations between the maternal serum zinc or copper levels and pregnancy outcome (birth weight and birth length). In this study, although the zinc and copper intake in most Thai pregnant women (99 and 58%, respectively) were less than two-thirds of the Thai RDAs, they were not at risk of suffering from zinc and copper deficiencies as determined by serum zine and copper concentrations, abnormal parturition and abnormal pregnancy outcome.

Serum Beta-hCG of 11 Days after Embryo Transfer to Predict Pregnancy Outcome

Objective To assess the clinic value of a single maternal serum beta-human chorionic gonadotropin （β-hCG） assay 11 d after embryo transfer in ART pregnancies and to predict pregnancy outcome. Methods A total of 384 pregnancies after embryo transfer were included. Inviable pregnancies were defined as biochemical pregnancies, ectopic pregnancies and first trimester abortions. Ongoing pregnancies were defined as singleton pregnancies and multiple pregnancies whose gestation were achieved more than 12 weeks. Serum β- hCG concentrations were compared among different groups. Results On the post embryo transfer d 11, the mean β-hCG concentration of the ongoing pregnancy group （323. 7±285.2 mIU/ml） was significantly higher than that of the inviable pregnancy group （81.4±68.1 mmIU /ml） （P〈 0. 001）. In multiple gestations, the levels of β-hCG were significantly higher compared with singleton pregnancies. If the β-hCG level was between 10 mIU/ml and 50 mIU/ml, the positive predictive value of biochemical pregnancies and ectopic pregnancies was 81.8%, the negative predictive value was 94.4%. If the level was less than 100 mIU/ml, the positive predictive value of first trimester abortions was 80.8%, the negative predictive value was 77.8%. If the level was greater than 250 mIU/ml, the positive predictive value of multiple pregnancies was 83.3%, the negative predictive value was 74.4%. Conclusions A single serum β-hCG level on d 11 after embryo transfer has good predictive value for clinical pregnancy outcome in controlled ovarian stimulation cycles and helps to plan the subsequent follow-up.

Value of increased fetal cardio thoracic ratio in predicting adverse pregnancy outcome in 11-13^(+6)weeks

Objective:To explore the value of increased fetal cardio thoracic ratio(CTR)in predicting adverse fetal pregnancy outcome during 11-13+6 weeks.Methods:The ultrasonographic features,chromosome or gene detection and the pregnancy outcome of 86 fetuses with increased CTR at 11-13+6 weeks’gestation were retrospectively analyzed.Fetuses were divided into non-structural malformation group(46 cases)and structural malformation group(40 cases)according to results of fetal ultrasound examination.The differences of CTR and nuchal translucency thickness(NT)between the two groups were compared by t test.The area under the curve(AUC)was calculated by constructing the receiver operating curve(ROC)to determine the best diagnostic threshold,sensitivity and specificity of CTR and NT in predicting chromosomal abnormalities.Results:All the 86 fetuses had serious problems such as chromosome or gene abnormalities,or structural malformations.The CTR and NT of the structural malformation group were significantly higher than those of the non-structural malformation group,and the difference was statistically significant(P<0.05).Through villous biopsy of 60 fetuses,47 cases(78.3%,47/60)with haemoglobin Bart’s disease,10 cases(16.7%,10/60)with chromosomal abnormalities were detected,and none abnormalities were detected in other 3 cases.According to the ROC curve,the AUC for CTR and NT to predict chromosomal abnormalities are 0.691 and 0.954,respectively,and the diagnostic cut-off values are 0.57 and 3.6 mm,respectively.The sensitivity is 60.0%and 100%,the specificity is about 79.6%and 85.7%,respectively.Follow-up showed that 5 cases of fetal were death intrauterine,and the remaining 81 cases were induced to labor.The specificity of CTR increase in predicting adverse pregnancy outcome was 100%.Conclusion:The increase of CTR in 11-13+6 weeks of gestation indicates that the fetus may have serious problems and poor clinical prognosis.Attention should be paid to the accurate evaluation of CTR in early pregnancy so as to provide reference for the prediction of fetal pregnancy outcome.

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.
