Pregnancy outcome after multifetal pregnancy reduction to twins compared with spontaneously conceived twins

Multifetal pregnancy reduction (MFPR) appears to be an efficaciousmethod for improving the perinatal outcome of ‘high order’multifetal gestations. The present study was undertaken to evaluatepregnancy outcomes after MFPR to twins in comparison with spontaneouslyconceived twins. In all, 10 patients with quadruplet gestations(group 1) and 30 patients with triplet gestations (group 2),who underwent MFPR to twins, were prospectively enrolled. Pregnancycomplications, gestational age at delivery, mode of deliveryand birthweights were compared with 30 consecutive spon-taneoustwin gestations (group 3) matched by maternal age and parity.Mean gestational age at delivery and mean birthweights weresignificantly lower in group 1, compared with groups 2 and 3(33.2, 35.9, 36.9 weeks, and 1843, 2209, 2361 g respectively).The incidence of pregnancy complications was significantly higherin group 1 compared with group 3. There was also a clear trendof increased incidence of specific pregnancy complications ingroup 1 compared with groups 2 and 3, especially premature contractions(PMC; 50, 27 and 13% respectively), and pregnancy-induced hypertension(PIH; 40, 23 and 7% respectively). In conclusion, the initialnumber of fetuses before reduction was inversely correlatedwith gestational age at delivery and birthweight, and positivelycorrelated with pregnancy complications. Contrary to previousstudies, we found a higher incidence of pregnancy complicationsafter MFPR compared with spontaneous twins, especially PMC andPIH.     

The Risk Factors and Pregnancy Outcomes of 48 Cases of Heterotopic Pregnancy from a Single Center

The purpose of this study was to investigate risk factors that are associated with heterotopic pregnancy (HP) following in vitro fertilization (IVF)-embryo transfer (ET) and to demonstrate the outcomes of HP after the surgical treatment of ectopic pregnancies. Forty-eight patients from a single center, who were diagnosed with HP between 1998 and 2012 were included. All of the patients had received infertility treatments, such as Clomid with timed coitus (n = 1, 2.1%), superovulation with intrauterine insemination (n = 7, 14.6%), fresh non-donor IVF-ET (n = 33, 68.8%), and frozen-thawed cycles (n = 7, 14.6%). Eighty-four additional patients were randomly selected as controls from the IVF registry database. HP was diagnosed at 7.5 ± 1.2 weeks (range 5.4-10.3) gestational age. In six cases (12.5%), the diagnosis was made three weeks after the patients underwent treatment for abortion. There were significant differences in the history of ectopic pregnancy (22.5% vs. 3.6%, P = 0.002). There were no significant differences in either group between the rates of first trimester intrauterine fetal loss (15.0% vs. 13.1%) or live birth (80.0% vs. 84.1%) after the surgical treatment for ectopic pregnancy. The risk factors for HP include a history of ectopic pregnancy (OR 7.191 [1.591-32.513], P = 0.010), abortion (OR 3.948 [1.574-9.902], P = 0.003), and ovarian hyperstimulation syndrome (OHSS) (OR 10.773 [2.415-48.060], P = 0.002). In patients undergoing IVF-ET, history of ectopic pregnancy, abortion, and OHSS may be risk factors for HP as compared to the control group of other IVF patients. The surgical treatment of HP does not appear to affect the rates of first trimester fetal loss or live birth.     

未足月胎膜早破残余羊水量过少81例临床分析

目的探讨未足月胎膜早破（PPROM）残余羊水量过少病人的并发症、分娩方式及母婴结局。方法回顾性分析在我院分娩的220例PPROM的临床资料,分残余羊水量过少组与对照组,对两组并发症、分娩方式及母儿结局进行比较。结果残余羊水量过少组在脐带脱垂、1分钟低Apgar评分、死胎死产、新生儿死亡的发生率显著高于对照组,有统计学差异,P值均〈0.05。且剖宫产率明显高于对照组,P〈0.001。结论对PPROM残余羊水量过少者应严密监测,如并发非头先露、胎儿窘迫、脐带脱垂,剖宫产是较为安全的分娩方式。     

A 3 year, prospectively-designed study of late selective multifetal pregnancy reduction

The aim of our study was to evaluate the pregnancy outcomes of late selective multifetal reduction (MFPR). We performed a 3 year, prospectively-designed study in which 28 patients underwent MFPR at a mean gestational age of 20.2 +/- 3.9 weeks (range 14-29 weeks). The indications for MFPR included: multiple gestation (> or = 3) (57%), structural anomaly (29%), and chromosomal abnormality (14%). The procedure was performed using ultrasonographically-guided intracardiac injection of potassium chloride. The mean gestational age at delivery was 36.6 +/- 2.2 weeks (range 31-40 weeks). Nine patients (32%) delivered before 36 weeks of gestation. The mean birth weight was 2370 +/- 614 g (range 1510-3250 g). Discordancy was evident in four twins (14%), and intrauterine growth retardation in four pregnancies. One case (3.5%) presented with oligohydramnios, and one with pregnancy- induced hypertension. One case of late abortion due to passive cervical dilatation 4 weeks after the MFPR was observed. Procedure-related amnionitis followed by late abortion occurred in one case. A total of 57% of the patients delivered vaginally and 43% delivered by Caesarean section. We concluded that late selective MFPR is associated with favourable perinatal outcome. Late MFPR may facilitate the detection of structural and chromosomal anomalies prior to the procedure, and the accomplishment of selective reduction of the affected fetus.      

未足月胎膜早破母婴结局的临床资料分析

目的探讨未足月胎膜早破（PPROM）的母婴预后。方法回顾性分析我院2004年1月-2008年12月收治的PPROM单胎妊娠的537例孕产妇的临床资料。结果孕23-32＋6周PPROM患者的死产率为83.3%,新生儿死亡率为63.3%,围产存活新生儿发病率与孕33-36＋6周的PPROM患者相比,两组差异具有统计学意义（均为P〈0.01）。PPROM患者的围产儿结局与破膜孕周密切相关。结论孕23-32＋6周PPROM的早产儿预后较差,在保守治疗期间应根据具体情况适时终止妊娠,而孕33-36＋6周PPROM患者建议在积极期待治疗期间及时分娩,以减少早产儿并发症。

Pregnancy outcomes and appropriate timing of pregnancy in 183 pregnancies in Korean patients with SLE

This study was undertaken to investigate the pregnancy outcomes in patients with systemic lupus erythematosus (SLE) and the appropriate timing of pregnancy. We performed a retrospective evaluation of 183 pregnancies with SLE at Catholic University Medical Center during the 13-year period from 1998 to 2010. Pregnancy outcomes were compared according to SLE characteristics. The predictive value of the different cut-off points of the stable period before conception on adverse pregnancy outcomes was calculated by ROC (Receiver operating characteristics) curve analysis. In multivariate analysis, the presence of antiphospholipid antibodies (aPLs) increased the risk of pregnancy loss (p<0.0001) and premature birth (p=0.0040). Active disease at conception increased the risk of premature birth (p< 0.0001) and complications (IUGR, PIH, or both) (p= 0.0078). The other predictor of complications was found to be lupus flare (p=0.0252). At a cut-off level of stable period of 4 months before conception, sensitivity and specificity were 70.8% and 53.2%, 71.4% and 61.5%, and 63.6 % and 59.8 %, respectively on reducing pregnancy loss, premature birth, and complications. Pregnancies with aPLs, active disease at conception and SLE flares are at a higher risk of adverse outcomes. It is essential that disease activity remains stable at least 4 months before conception, for favorable pregnancy outcomes.     

深圳地区羊水过少226例临床分析

目的探讨羊水过少与妊娠并发症的关系及其分娩方式的选择与围生儿预后关系。方法收集我院2005年6月至2006年5月住院分娩的羊水过少孕妇226例,随机抽取我院同期分娩的羊水量正常孕妇220例为对照组,两组病例就妊娠并发症、分娩方式及围生儿情况进行比较。结果羊水过少组中过期妊娠、妊娠期高血压疾病、胎儿生长受限（FGR）及胎儿畸形的发生率均高于对照组（P〈0.01）。羊水过少组羊水粪染、胎儿窘迫、胎粪吸入综合征（MAS）的发生率明显高于对照组（P〈0.05,P〈0.01）。羊水过少伴妊娠并发症组羊水粪染、胎儿窘迫、新生儿窒息的发生率明显高于无并发症组,（P〈0.01,P〈0.05）,剖宫产率明显增加（P〈0.01）,而胎粪吸入综合征（MAS）与围生儿死亡率无显著差异（P〉0.05）。单纯羊水过少者围生儿结局与对照组无显著差异（P〉0.05）。结论羊水过少与妊娠并发症密切相关,羊水过少伴有妊娠并发症者围生儿结局不良,应放宽手术指征,单纯羊水过少者可以阴道试产。     

Perinatal outcome in twin pregnancies complicated by gestational diabetes mellitus: a comparative study

The purpose of this study is to compare perinatal outcomes of twin pregnancies complicated by gestational diabetes (GDM) with those unaffected by GDM. A total of 1,154 twin pregnancies who delivered at Cheil General Hospital, between January 1998 and December 2002 were recruited to participate in a retrospective analysis. Out of these twin pregnancies, 37 women were had GDM. Four pregnancies exposed to GDM were excluded due to the loss of medical records; therefore 33 twin pregnancies exposed to GDM were enrolled. We matched the GDM pregnancies with pregnancies unaffected by GDM in a 1:2 ratio; therefore there were 33 GDM/66 without GDM who delivered during the study period. Our findings show that there were no significant differences including birth weight, Apgar score, respiratory distress syndrome, meconium aspiration pneumonia, transient tachypnea of new born, hyperbilirubinemia, hypoglycemia, hypocalcemia and congenital anomalies. Therefore, well controlled GDM may not increase perinatal complications in twin pregnancies. Careful pregnancy management and fetal surveillance in twin pregnancies is important to decrease perinatal complications and maintain a sound pregnancy and healthy offspring.

目的探讨妊娠肝内胆汁淤积症(ICP)孕妇肝胆B超特点,评价肝胆系B超检查产前预测ICP孕妇病情轻重和围生儿预后的临床意义.方法根据B超有无肝内胆管扩张表现将ICP孕妇分为观察组(12例)和对照组(20例),用SPSS13.0统计软件回顾性分析两组孕妇症状的轻重和转氨酶、胆红素、胆汁酸等生化指标以及围生儿预后情况.结果观察组孕妇重症者比例显著高于对照组(P＜0.05),且瘙瘁出现的时间显著早于对照组(t=2.06,P＜0.05);观察组生化指标ALT、AST、TBA、TBIL显著高于对照组(P＜0.01),DBIL观察组虽有高于对照组趋势但无显著性差异(P＞0.05);观察组胎儿窘迫、新生儿窒息发生率显著高于对照组(P＜0.05),分娩孕周和新生儿体重明显低于对照组(t=3.52,P＜0.01;t=2.11,P＜0.05).结论ICP孕妇若肝胆B超有肝内胆管扩张表现提示病情严重、围生儿预后差,应积极保肝利胆治疗,有条件者还可进行血浆置换并适时剖宫产终止妊娠.     

Prospective observational study of bone mineral density during pregnancy: low molecular weight heparin versus control

BACKGROUND: The aim of this study was to assess the effect of long-term low molecular weight heparin (LMWH) on bone mineral density (BMD) during pregnancy. METHODS: Fifty-five patients with recurrent miscarriage and known thrombophilia (antiphospholipid syndrome) were followed through pregnancy in an ethically approved prospective observational study. All women had dual energy X-ray absorptiometry (DEXA) scans at the lumbar spine (L1-L4) performed within 6 months prior to conception and in the immediate post-natal period, within 6 weeks of delivery. LMWH (5000 U/day) plus low-dose aspirin was commenced after a positive urine pregnancy test and continued throughout pregnancy and after delivery until 6 weeks post-partum. A group of 20 volunteers with recurrent miscarriage, not requiring any treatment intervention, acted as controls and were monitored in an identical fashion. RESULTS: Characteristics were not significantly different between treated patients and controls. Both groups showed a similar loss in lumbar spine (L1-L4) BMD by the end of the pregnancy [LMWH 4.17% or 0.045 g/cm(3), 95% confidence interval (CI) 0.036-0.062 versus control 3.56% or 0.043 g/cm(3), 95% CI 0.027-0.059]. However, the difference in bone loss between the groups was not statistically significant (0.002 g/cm(3), CI -0.0124 to 0.00865; P = 0.88). No patient suffered vertebral fracture. CONCLUSIONS: Bone loss associated with the use of long-term LMWH is not significantly different from physiological losses during pregnancy.     

How does subchorionic hematoma in the first trimester affect pregnancy outcomes?

IntroductionSubchorionic hematoma (SCH) in pregnancy has been associated with increased risk of adverse pregnancy outcomes. We aimed to investigate the association of SCH with adverse pregnancy outcomes in pregnant women in relation to size of hematoma and control subjects.Material and methodsThis study included 178 pregnant women with sono-graphically detected SCH in the 1^st trimester, and 350 pregnant controls without SCH. Data on maternal age, smoking status, gestational week at diagnosis, location of SCH, medications before diagnosis, gestational week at delivery, delivery route and pregnancy outcomes (first trimester vaginal bleeding, pre-eclampsia, gestational diabetes, intrauterine growth restriction (IUGR), placental abruption, preterm delivery < 37 weeks, early pregnancy loss and intrauterine death) were retrieved retrospectively from hospital records. Pregnant women with SCH were divided into 3 groups according to the size of hematoma including small SCH (SCH-I group, n = 47), medium-size SCH (SCH-II group, n = 110) and large SCH (SCH-III group, n = 21) groups.ResultsSubchorionic hematoma was associated with significantly lower gestational age at delivery (p < 0.001) and higher rate of first trimester bleeding (p < 0.001) compared with the control group, regardless of the size of the hematoma. Placental abruption (p = 0.002) and early pregnancy loss (p < 0.001) were significantly more common in SCH-II and -III groups than in the control group. SCH-III group was associated with a significantly higher rate of < 37 gestational weeks at delivery (p < 0.001), first trimester vaginal bleeding (p < 0.001), early pregnancy loss (p < 0.001), IUGR (p = 0.003) and preterm delivery (p < 0.001) compared to both lesser size hematoma and control groups.ConclusionsOur findings suggest that large SCH might indicate an increased risk of adverse pregnancy outcomes such as 1^st trimester vaginal bleeding, early pregnancy loss, IUGR, placental abruption or preterm delivery. These findings are important to guide the patients with SCH for detailed clinical evaluation.     

Interval from Prostate Biopsy to Radical Prostatectomy Does Not Affect Immediate Operative Outcomes for Open or Minimally Invasive Approach

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsy before radical prostatectomy. The aim of our study was to evaluate whether the interval from prostate biopsy to radical prostatectomy affects immediate operative outcomes, with a focus on differences in surgical approach. The study population of 1,848 radical prostatectomy patients was divided into two groups according to the surgical approach: open or minimally invasive. Open group included perineal and retropubic approach, and minimally invasive group included laparoscopic and robotic approach. The cut-off of the biopsy-to-surgery interval was 4 weeks. Positive surgical margin status, operative time and estimated blood loss were evaluated as endpoint parameters. In the open group, there were significant differences in operative time and estimated blood loss between the <4-week and ≥4-week interval subgroups, but there was no difference in positive margin rate. In the minimally invasive group, there were no differences in the three outcome parameters between the two subgroups. Multivariate analysis revealed that the biopsy-to-surgery interval was not a significant factor affecting immediate operative outcomes in both open and minimally invasive groups, with the exception of the interval ≥4 weeks as a significant factor decreasing operative time in the minimally invasive group. In conclusion, performing open or minimally invasive radical prostatectomy within 4 weeks of prostate biopsy is feasible for both approaches, and is even beneficial for minimally invasive radical prostatectomy to reduce operative time.

Early transvaginal embryo aspiration: a safer method for selective reduction in high order multiple gestations.

Assisted reproduction technologies and ovulation induction for treatment of infertility continue to cause high order multiple gestations. Increased perinatal morbidity and mortality, as well as maternal morbidity, may complicate these pregnancies. Selective fetal reduction, an acceptable therapeutic approach in these cases, is usually performed at or after the ninth week of gestation, with KCl injected in the vicinity of the fetal heart, and is associated with a total pregnancy loss rate of 11.7%. We report our experience with 90 women who underwent early (mean 7.5 weeks gestation, range 7. 0-8.0 weeks) transvaginal selective embryo aspiration. The mean number of viable embryos before and after reduction was 3.5 and 2.1 respectively. Six (6.7%) pregnancies were lost before 24 gestational weeks. One miscarriage occurred at the tenth gestational week. The other five pregnancies were aborted at 17.3-21.6 weeks gestation. Additional interventions were performed in three of these pregnancies: genetic amniocentesis in two cases and cervical suture in one case. In the subset of 39 patients with>/=4 embryos, only one (2.6%) pregnancy loss was recorded. This loss rate is significantly lower (P < 0.05) than the 15.3% loss rate in patients with >/=4 fetuses calculated from other work. Four (4.4%) other pregnancies were complicated by premature delivery (25-28 weeks gestation). Mean gestational age of delivered pregnancies in our series was 35.7 weeks. In conclusion, early transvaginal embryo aspiration is a simple and relatively safe method for multiple pregnancy reduction. The overall pregnancy loss rate associated with early embryo aspiration is similar to that of procedures performed at later gestational age, but is significantly lower when the initial number of embryos is four or greater.

目的探讨妊娠合并甲亢规范化治疗对妊娠结局的影响。方法选取四年间于我院建档并分娩、资料完整的妊娠合并甲亢患者77例,对其妊娠结局进行临床分析。结果甲亢未治疗组甲状腺激素水平明显增高,妊娠并发症增多,与治疗组相比,差异有显著性（P〈0.01）;未治疗组新生儿体重明显低于治疗组,差异有显著性（P〈0.05）;但两组的剖宫产率及新生儿甲状腺功能差异无统计学意义（P〉0.05）。结论及时诊断并规范治疗妊娠甲亢,可降低妊娠并发症发生率,改善妊娠结局。     

孕妇唐氏筛查结果中人绒毛膜促性腺激素增高与妊娠结局的关系分析

目的 研究并分析孕妇唐氏筛查结果中人绒毛膜促性腺激素(HCG)增高与妊娠结局的关系,为优生提供参考.方法 选取2014年2月至2016年2月在我院就诊的产妇268例.其中HCG水平增高产妇134例设为观察组,HCG水平正常产妇134例设为对照组.对比两组妊娠结局异常发生率.此外,将观察组产妇根据HCG水平不同分为2.5MoM＜ HCG＜3MoM组(70例),HCG＞3MoM组(64例),对比两组妊娠结局的异常发生率.结果 观察组胎儿畸形、胎盘异常、巨大儿发生率均显著高于对照组;HCG ＞3MoM组产妇胎儿畸形、胎盘异常、巨大儿发生率均显著高于2.5MoM＜ HCG ＜3MoM产妇,上述差异均有统计学意义(均P＜0.05).HCG升高与胎儿畸形、胎盘异常、巨大儿均呈显著正相关(r=0.813,P=0.000:r =0.685,P=0.000;r =0.734,P=0.000).结论 随着孕妇唐氏筛查结果中HCG逐渐增高,妊娠异常发生率也随之上升,应引起重视.     

Previous pregnancy outcome is an important determinant of subsequent pregnancy outcome in women with systemic lupus erythematosus.

Women with systemic lupus erythematosus (SLE) have increased adverse pregnancy outcomes. The reasons for these problems include maternal disease, clinical or serologic activity, medication use, and residual organ impairment from prior disease flares. In retrospective studies, pregnancy data are often treated cross-sectionally, with births rather than mothers as the unit of analysis. Multiple pregnancies from the same mother may be highly correlated with each other. In an unmatched retrospective study, the first two pregnancy outcomes in lupus patients with anticardiolipin antibody (anti-CL IgG or IgM isotype) (cases N = 47) and without anticardiolipin antibody (controls, N = 125) were assessed according to birth order. A good outcome was defined as a full-term (> 38 weeks) live birth without neonatal complications. All other pregnancy outcomes were considered adverse outcomes. Therapeutic abortions and ectopic or molar pregnancies were excluded. Both cases and controls with an adverse outcome in their first pregnancy had at least a 50% chance of another adverse outcome in their second pregnancy. Cases with a late miscarriage (fetal loss at 14 to 20 weeks' gestation) in their first pregnancy had the highest risk, 80%, of an adverse outcome in their second pregnancy. Both previous pregnancy loss and anti-CL antibody status should be considered in the analysis of pregnancy outcomes in women with SLE.     

妊娠合并肺动脉高压严重程度对围生期结局的影响

目的 探讨妊娠合并肺动脉高压（PAH）患者的临床情况、处理方法及母儿结局。方法 回顾性分析2016年1月~2018年12月在华中科技大学同济医学院附属同济医院收治的26例妊娠合并肺动脉高压患者的临床资料,根据肺动脉收缩压分为轻中度PAH患者及重度PAH患者,比较不同程度PAH患者的病因、心功能分级、终止妊娠孕周、方式及母儿结局。结果 重度PAH患者心功能Ⅲ~Ⅳ级者占66.67%,高于轻中度PAH患者的42.86%,但差异无统计学意义（P＞0.05）;重度PAH患者终止妊娠孕周为（28.98±12.01）周,早于轻中度PAH患者的（36.79±3.00）周,差异有统计学意义（P＜0.05）;重度PAH患者全麻率高于轻中度PAH患者（66.67% vs 7.14%）,差异有统计学意义（P＜0.05）;重度PAH患者术中氧饱和度和输液量低于轻中度PAH患者、新生儿出生体重轻及小于胎龄儿发生率高,差异有统计学意义（P＜0.05）;重度PAH患者死亡率、新生儿窒息率高于轻中度PAH患者,但差异无统计学意义（P＞0.05）,重度PAH孕妇的新生儿平均体重、小于胎龄儿发生率高于轻中度PAH孕妇,差异有统计学意义（P＜0.05）。结论 妊娠合并PAH患者肺动脉压力越高,围生结局越差,重度PAH患者妊娠可危及母婴健康和生命,不宜妊娠,可妊娠的轻中度患者应在多学科专家的严密监护下妊娠,并选择恰当方式适时终止妊娠,以改善母儿结局。
