Abstract
Background Congenital heart disease (CHD) is the most prevalent congenital malformation affecting 1 in 100 newborns. While advances in early diagnosis and postnatal management have increased survival in CHD children, worrying long-term outcomes, particularly neurodevelopmental disability, have emerged as a key prognostic factor in the counseling of these pregnancies. Methods Eligible participants are women presenting at 20 to < 37 weeks of gestation carrying a fetus with CHD. Maternal/neonatal recordings are performed at regular intervals, from the fetal period to 24 months of age, and include: placental and fetal hemodynamics, fetal brain magnetic resonance imaging (MRI), functional echocardiography, cerebral oxymetry, electroencephalography and serum neurological and cardiac biomarkers. Neurodevelopmental assessment is planned at 12 months of age using the ages and stages questionnaire (ASQ) and at 24 months of age with the Bayley-III test. Target recruitment is at least 150 cases classified in three groups according to three main severe CHD groups: transposition of great arteries (TGA), Tetralogy of Fallot (TOF) and Left Ventricular Outflow Tract Obstruction (LVOTO). Discussion The results of NEURO-HEART study will provide the most comprehensive knowledge until date of children’s neurologic prognosis in CHD and will have the potential for developing future clinical decisive tools and improving preventive strategies in CHD. Trial registration NCT02996630, on 4th December 2016 (retrospectively registered).

Abstract
OBJECTIVE To assess potential differences in the expression of antiangiogenic and angiogenic factors and of genes associated with chronic hypoxia in cerebral tissue of euploid fetuses with congenital heart disease (CHD) vs those without. METHODS Cerebral tissue was obtained from 15 fetuses with CHD and 12 control fetuses that had undergone termination of pregnancy. Expression profiles of the antiangiogenic factor soluble fms-like tyrosine kinase-1 (sFlt-1), the angiogenic vascular endothelial growth factor-A (VEGF-A) and placental growth factor (PlGF), and of genes associated with chronic hypoxia were determined by real-time polymerase chain reaction in tissue from the frontal cortex and the basal ganglia of the fetuses. RESULTS Expression of sFlt-1 was 48% higher in the frontal cortex (P = 0.0431) and 72% higher in the basal ganglia (P = 0.0369) of CHD fetuses compared with controls. The expression of VEGF-A was 60% higher (P = 0.0432) and that of hypoxia-inducible factor 2-alpha was 98% higher (P = 0.0456) in the basal ganglia of CHD fetuses compared with controls. No significant differences were observed between the two groups in the expression of PlGF and hypoxia-inducible factor 1-alpha. CONCLUSION An overall dysregulation of angiogenesis with a net balance towards an antiangiogenic environment was observed in the cerebral tissue of fetuses with CHD, suggesting that these fetuses may have an intrinsic angiogenic impairment that could contribute to impaired brain perfusion and abnormal neurological development later in life.

Abstract
Objectives: The aim of this study was to evaluate the relationships between brain injury biomarkers in intrauterine growth-restricted (IUGR) infants (S100B and neuron-specific enolase (NSE)) and neurodevelopment at 2 years of age. Methods: This prospective case-control study was a cooperative effort among Spanish Maternal and Child Health Network (Retic SAMID) hospitals. At inclusion, biometry for estimated fetal weight and feto-placental Doppler variables were measured for each infant. Maternal venous blood and fetal umbilical arterial blood samples were collected at the time of delivery and neural injury markers S100B and NSE concentrations were measured. Neurodevelopment was evaluated at 2 years of age using the Bayley Scales of Infant and Toddler Development, third edition (Bayley-III). Results: Fifty six pregnancies were included. Thirty-one infants were classified as IUGR and 25 as non-IUGR. Neurodevelopmental evaluation at 2 years of age indicated that there were no between-group differences for any of the tests. For all patients in both groups, we found statistically significant inverse relationships between the concentrations of NSE in the cord blood and the results of the cognitive test (r = -271, p = .042), fine motor subtest (r = -280, p = .036), and social-emotional test (r = -349, p = .015). We also found statistically significant differences between the concentrations of S100B in the cord blood and the results of the cognitive test (r = -306, p = .022) and expressive communication subtest (r = -304, p = .023). For the IUGR group, we found a significant inverse relationship between the concentrations of S100B in the maternal serum and the results of adaptive behavior test (p < .05). In the non-IUGR group, we found statistically significant inverse relationships between the concentration of NSE in the cord blood and the results of the fine motor subtest (r = -446, p = .025) and social-emotional test (r = -489, p = .021). The difference between the concentration of S100B in the cord blood and the language composite score was also statistically significant (p = .038). Conclusions: At 2 years of age, the concentrations of NSE and S100B were higher in the non-IUGR and IUGR groups with the worst scores for some areas of neurodevelopmental evaluation. The value of these biomarkers for prognostic neurodevelopmental use requires further investigation for both non-IUGR and IUGR infants.

Abstract
OBJECTIVES To ascertain whether screening for pre-eclampsia (PE) and intrauterine growth restriction (IUGR) by uterine artery (UtA) Doppler in the second trimester of pregnancy and targeted surveillance improve maternal and perinatal outcomes in an unselected population. METHODS This was a multicenter randomized open-label controlled trial. At the routine second-trimester anomaly scan, women were assigned randomly to UtA Doppler or non-Doppler groups. Women with abnormal UtA Doppler were offered intensive surveillance at high-risk clinics of the participating centers with visits every 4 weeks that included measurement of maternal blood pressure, dipstick proteinuria, fetal growth and Doppler examination. The primary outcome was a composite score for perinatal complications, defined as the presence of any of the following: PE, IUGR, spontaneous labor < 37 weeks' gestation, placental abruption, stillbirth, gestational hypertension, admission to neonatal intensive care unit and neonatal complications. Secondary outcomes were a composite score for maternal complications (disseminated intravascular coagulation, maternal mortality, postpartum hemorrhage, pulmonary edema, pulmonary embolism, sepsis), and medical interventions (for example, corticosteroid administration and induction of labor) in patients developing placenta-related complications. RESULTS In total, 11 667 women were included in the study. Overall, PE occurred in 348 (3.0%) cases, early-onset PE in 48 (0.4%), IUGR in 722 (6.2%), early-onset IUGR in 93 (0.8%) and early-onset PE with IUGR in 32 (0.3%). UtA mean pulsatility index > 90(th) percentile was able to detect 59% of early-onset PE and 60% of early-onset IUGR with a false-positive rate of 11.1%. When perinatal and maternal data according to assigned group (UtA Doppler vs non-Doppler) were compared, no differences were found in perinatal or maternal complications. However, screened patients had more medical interventions, such as corticosteroid administration (relative risk (RR), 1.79 (95% CI, 1.4-2.3)) and induction of labor for IUGR (RR, 1.36 (95% CI, 1.07-1.72)). In women developing PE or IUGR, there was a trend towards fewer maternal complications (RR, 0.46 (95% CI, 0.19-1.11)). CONCLUSIONS Routine second-trimester UtA Doppler ultrasound in an unselected population identifies approximately 60% of women at risk for placental complications; however, application of this screening test failed to improve short-term maternal and neonatal morbidity and mortality.

Abstract
Non-immune neonates and non-immune pregnant women are at risk of developing rubella, measles and mumps infections, including congenital rubella syndrome. We describe the seroepidemiology of measles, mumps and rubella (MMR) in neonates and pregnant women in Catalonia (Spain). Anti-rubella, anti-measles and anti-mumps serum IgG titres were assessed using enzyme-linked immunosorbent assay (ELISA) tests in 353 cord blood samples from neonates of a representative sample of pregnant women obtained in 2013. The prevalence of protective antibody titres in neonates was 96 % for rubella IgG (≥8 IU/ml), 90 % for measles IgG (>300 IU/ml) and 84 % for mumps IgG (>460 EU/ml). Slightly lower prevalences of protective IgG titres, as estimated from the cord blood titres, were found in pregnant women: 95 % for rubella IgG, 89 % for measles IgG and 81 % for mumps IgG. The anti-measles and anti-mumps IgG titres and the prevalences of protective IgG titres against measles and mumps increased significantly (p < 0.001) with maternal age. The prevalence of protective anti-measles IgG titres decreased by 7 % [odds ratio (OR) = 0.15, p < 0.001), the prevalence of protective anti-rubella IgG titres increased by 3 % (OR = 1.80, p < 0.05) and the MMR vaccination coverage (during childhood) in pregnant women increased by 54 % (OR = 2.09, p < 0.001) from 2003 to 2013. We recommend to develop an MMR prevention programme in women of childbearing age based on mass MMR vaccination or MMR screening and vaccination of susceptible women to increase immunity levels against MMR.

Abstract
OBJECTIVES To evaluate the perinatal results of infants born between 23 and 25.6 weeks of gestation. METHODS Medical charts of all women giving birth prematurely (23-25.6 w) from January 2005 to December 2011 were retrospectively reviewed. Cases of malformed infants or deliveries elsewhere were excluded. RESULTS 198 infants were included. Chorioamnionitis occurred in 86 (43.4%) of the whole group: 26 (86.7%) in the 23-week; 35 (53.8%) in the 24-week and 25 (24.3%) in the 25-week groups. Foetal maturation with antenatal corticosteroids was complete in 119 cases (60.1%): 4 (13.3%) in the 23-week; 35 (53.8%) in the 24-week and 80 (77.7%) in the 25-week groups. Foetal death at birth occurred in 22 cases (11%) and 61 newborns (30.8%) died in the neonatal period. Of the 106 survivors with 2 years complete follow-up, 45 infants (42.4%) did not present sequelae; 16 infants (15.1%) had severe sequelae. A 66.6% (4) of infants born at 23 weeks of gestation did not present sequelae compared with a 32.3% (11) at 24 weeks and 45.4% (30) at 25 weeks. CONCLUSIONS The chorioamnionitis rate was higher when gestational age was lower. The foetal maturation rate was higher when gestational age was higher. A low severe sequelae rate was observed in the whole series, particularly in the 23-week group where the rate was lower than expected; however, these results could have been influenced by the small size of the 23-week group.

Abstract
OBJECTIVE To investigate the relationship between fetal heart defects and maternal serum placental growth factor (PlGF), a marker of placental angiogenesis. METHODS Maternal serum PlGF, pregnancy-associated plasma protein-A (PAPP-A) and uterine artery pulsatility index (UtA-PI) at 11-13 weeks' gestation were compared in 68 cases of isolated fetal major heart defects and 340 normal controls. Variables were converted into multiples of the median (MoM) after adjustment for gestational age, maternal age, racial origin, weight, parity and method of conception, and then compared between groups. The cardiac defects included 11 cases of obstruction of the left ventricular outflow tract (LVOT), 25 conotruncal abnormalities and 32 valve defects. RESULTS The median PlGF-MoM in the heart defect group was lower than in controls (0.80 (interquartile range (IQR), 0.57-1.08) vs 1.00 (IQR, 0.79-1.32); P < 0.0001). Low PlGF levels were observed in the presence of conotruncal and valve defects but not in the presence of LVOT defects. There was no significant difference between the group with fetal heart defects and controls in PAPP-A-MoM (0.95 (IQR, 0.68-1.28) vs 1.01 (IQR, 0.70-1.39); P = 0.292) or UtA-PI-MoM (1.01 (IQR, 0.84-1.28) vs 0.99 (IQR, 0.80-1.20); P = 0.396). CONCLUSION In pregnancies with isolated fetal heart defects there is evidence of impaired placental angiogenesis in the absence of impaired placental perfusion and function.

Abstract
Mirror syndrome is a rare condition that involves fetal hydrops, placentomegaly and severe maternal edema. The pathogenesis of this syndrome mimics endothelial dysfunction observed in pre-eclampsia. We report a case of maternal mirror syndrome caused by bilateral fetal hydrothorax that resolved after intrauterine pleuroamniotic shunt placement. At the time of the clinical manifestation there was an antiangiogenic state similar to that seen in pre-eclampsia, which resolved after fetal treatment. Our findings suggest that mirror syndrome is a manifestation of a broad spectrum of pathological conditions that induces an antiangiogenic state.

Abstract
BACKGROUND The risk of pre-eclampsia (PE) increases in twin pregnancies, especially when assisted reproduction technologies (ART) are used. The aim of this study was to assess angiogenic/anti-angiogenic factors in maternal serum in the first trimester of twin pregnancies and establish if the mode of conception influences angiogenic status. METHODS This prospective study enrolled women with twin (n = 61) and singleton (n = 50) pregnancies. Dichorionic twin pregnancies were divided into two groups according to their mode of conception. Singleton pregnancies were used as the control group. Soluble fms-like tyrosine kinase (sFlt-1), free placental growth factor (PlGF) and soluble endoglin (sEng) concentrations were measured in the first trimester maternal serum. RESULTS In the first trimester, women with twin pregnancies had higher serum concentrations of the anti-angiogenic factor sFlt-1 than that with singleton pregnancies (3924 ± 250 versus 2426 ± 162 pg/ml, respectively; P < 0.001). Maternal serum PlGF concentrations were lower in singleton pregnancies than those in twin pregnancies (37 ± 3.7 versus 59 ± 5.6, respectively; P < 0.001). Serum concentrations of sFlt-1 were higher in twin pregnancies conceived by ART than those in spontaneous twin pregnancies (4313 ± 389 versus 3522 ± 300 pg/ml, respectively; P < 0.05). No differences between groups were observed for sEng. CONCLUSIONS In the first trimester, twin pregnancies conceived using ART showed a heightened anti-angiogenic status that could explain the increased risk of PE in these cases.

Abstract
OBJECTIVES The aims of this study were to describe and assess the feasibility of measuring cervical length by standard transvaginal sonography (TVS) and transperineal sonography (TPS) in women with a cervical pessary and compare these measurements with those obtained with a new transvaginal technique. METHODS Measurement of cervical length by TPS was attempted immediately before measurement using TVS in 48 women with a cervical pessary at between 22 and 23 weeks' gestation. The TVS procedure consisted of two types of measurement: in the first, the probe was placed on the anterior fornix (standard technique) and in the second, the probe was inserted into the pessary to touch the anterior cervical lip (new technique). Two physicians consecutively performed these procedures and compared the measurements obtained. Intraclass correlation coefficients (ICCs) with 95% CI were used to evaluate interobserver reliability, and Bland-Altman analysis was used to assess interobserver agreement. RESULTS In total, 258 measurements (obtained from 43 women) were analyzed. Interobserver ICCs of the measurements obtained were 0.58 (95% CI, 0.34-0.75) for TPS, 0.65 (95% CI, 0.44-0.79) for the standard TVS technique and 0.97 (95% CI, 0.95-0.98) for the new TVS technique. Bland-Altman analysis showed small mean differences between measurements obtained by two physicians for the three methods, but with narrower limits of agreements (LOA) for the new TVS technique: TPS mean difference - 0.99 mm (95% LOA, - 13.23 to 11.25 mm), standard TVS technique mean difference - 0.23 mm (95% LOA, - 10.90 to 10.44 mm) and new TVS technique mean difference - 0.01 mm (95% LOA, - 2.57 to 2.55 mm). It was apparent from the images obtained that the external os was not visible in 89% of cases when either the TPS or standard TVS technique was used. However, the external os was visible in all cases when the new TVS method was used. CONCLUSIONS We propose a new technique for measuring and monitoring cervical length in women with a cervical pessary that provides improved visualization of the cervix and increased reliability in comparison to established techniques.

Abstract
BACKGROUND Sister chromatid cohesion is essential for ordered chromosome segregation at mitosis and meiosis. This is carried out by cohesin complexes, comprising four proteins, which seem to form a ring-like complex. Data from animal models suggest that loss of sister chromatid cohesion may be involved in age-related non-disjunction in human oocytes. Here, we describe the distribution of cohesins throughout meiosis in human oocytes. METHODS We used immunofluorescence in human oocytes at different meiotic stages to detect cohesin subunits REC8, STAG3, SMC1 beta and SMC3, [also synaptonemal complex (SC) protein 3 and shugoshin 1]. Samples from euploid fetuses and adult women were collected, and 51 metaphase I (MI) and 113 metaphase II (MII) oocytes analyzed. SMC1 beta transcript levels were quantified in 85 maturing germinal vesicle (GV) oocytes from 34 women aged 19-43 years by real-time PCR. RESULTS At prophase I, cohesin subunits REC8, STAG3, SMC1 beta and SMC3 overlapped with the lateral element of the SC. Short cohesin fibers are observed in the oocyte nucleus during dictyate arrest. All four subunits are observed at centromeres and along chromosomal arms, except at chiasmata, at MI and are present at centromeric domains from anaphase I to MII. SMC1 beta transcripts were detected (with high inter-sample variability) in GV oocytes but no correlation between SMC1 beta mRNA levels and age was found. CONCLUSIONS The dynamics of cohesins REC8, STAG3, SMC1 beta and SMC3 suggest their participation in sister chromatid cohesion throughout the whole meiotic process in human oocytes. Our data do not support the view that decreased levels of SMC1 beta gene expression in older women are involved in age-related non-disjunction.

Abstract
OBJECTIVES To assess the feasibility and impact on perinatal outcome of fetoscopic laser coagulation of placental anastomoses in monochorionic twins with selective intrauterine growth restriction (sIUGR) and intermittent absent or reversed end-diastolic flow (iAREDF) in the umbilical artery (Type III), in comparison with expectant management. METHODS This is a descriptive study of the outcome of 18 cases of monochorionic twins with Type III sIUGR treated with laser, and 31 pregnancies managed expectantly over the same period. All newborns underwent neonatal brain ultrasound scans. Perinatal outcome and the incidence of neurological damage were compared between the two groups. RESULTS Laser coagulation could be performed in only 88.9% (16/18) of cases owing to technical difficulties, and in 12.5% (2/16) a second procedure was required to achieve complete coagulation of the large artery-to-artery anastomosis. Mean gestational age at delivery was 31.0 (range, 26-33) weeks in the expectant management group and 32.6 (range, 23-38) weeks in the laser group (P = 0.32). Overall perinatal survival was 85.5% (53/62) and 63.9% (23/36), respectively (P = 0.02). Intrauterine demise of the smaller twin occurred in 19.4% (6/31) and 66.7% (12/18), respectively (P = 0.001), and was associated with death of the cotwin in 50% (3/6) and 0% (0/12) of these cases, respectively (P = 0.02). The prevalence of periventricular leukomalacia in the larger fetus was 4/28 (14.3%) in the expectant management group and 1/17 (5.9%) in the laser group (P = 0.63). CONCLUSIONS Laser coagulation in sIUGR-iAREDF pregnancies is technically difficult and not always feasible. Placental dichorionization significantly increases the proportion of fetuses with intrauterine death of the growth-restricted twin, but it protects the normal twin from its cotwin's death in the event of demise of the growth-restricted twin.

Abstract
OBJECTIVES To investigate potential differences in the prediction of early- vs. late-onset pre-eclampsia and/or intrauterine growth restriction (PE/IUGR) by second-trimester uterine artery Doppler examination, and measurement of maternal serum placental growth factor (PlGF) and soluble fms-like tyrosine kinase 1 (sFlt1). METHODS Uterine artery mean pulsatility index (PI) and maternal serum PlGF and sFlt1 levels were measured at 24 weeks of gestation in 76 healthy pregnant women and 38 cases of PE/IUGR, of which 19 were defined as early onset (< 32 weeks). RESULTS For a specificity of 95%, the sensitivities of uterine artery mean PI, PlGF and sFlt1 for early-onset PE/IUGR were 47.4%, 84.4% and 36.8%, respectively. When combining uterine artery Doppler with PlGF, the sensitivity for identifying early-onset PE/IUGR was 89.5% with a specificity of 95%. Conversely, the sensitivity for late-onset PE/IUGR was below 11% for all parameters analyzed. CONCLUSIONS Angiogenic factors and uterine artery Doppler evaluation may be useful second-trimester screening tests for early-onset, but not late-onset, PE/IUGR.

Abstract
OBJECTIVE To evaluate the prevalence of hypertrophic cardiomyopathy-like (HCL) changes in monochorionic twins with selective intrauterine growth restriction (sIUGR) and intermittent absent/reversed end-diastolic flow (iAREDF), also defined as Type III sIUGR, and the clinical relevance of this condition. METHODS A total of 80 pregnancies with sIUGR were studied, 40 with, and 40 without iAREDF. HCL changes were defined as an increased thickness of either left or right ventricular wall (mean > 2 SD) estimated with M-mode ultrasonography. Data were plotted on normal reference values constructed from 75 uncomplicated monochorionic twin pregnancies (150 fetuses) at 22-34 weeks' gestation. Perinatal outcomes in pregnancies with and without HCL changes were compared. RESULTS In the group with iAREDF, 8/40 of the larger twins (20%) had HCL changes (five bilaterally, two in the right, and one in the left ventricle) as compared with 1/40 (2.5%) in fetuses without iAREDF (P = 0.03). No differences were observed in the smaller twin (1/40 in both groups). HCL changes were not associated with a significant increment in perinatal mortality as only one large fetus from the group with iAREDF died in utero. In the remaining 10 cases, no differences in the intertwin weight discordance, placental surface discordance, or rate of neonatal neurological damage were observed. However, all 10 presented mildly abnormal neonatal cardiac findings that resolved over time with no apparent short-term impact on cardiac function. CONCLUSIONS HCL changes in the larger twin should be regarded as part of the spectrum of findings in Type III monochorionic-sIUGR (presenting iAREDF). This finding does not seem to be associated with an increased rate of short-term neurological or cardiac complications.

Abstract
OBJECTIVE To evaluate changes in the temporal evolution and regional distribution of arterial brain Doppler parameters in relation to different stages of hemodynamic adaptation in fetuses with severe intrauterine growth restriction (IUGR). METHODS Thirty-six fetuses with severe IUGR (<or= 32 weeks of gestation) and abnormal umbilical artery (UA) pulsatility index (PI) (mean > 2 SD) were evaluated longitudinally with pulsed Doppler ultrasound at four different hemodynamic stages: Stage 1 (n = 36), mean UA-PI > 2 SD or absent UA end-diastolic flow; Stage 2 (n = 34), abnormal middle cerebral artery (MCA) PI (mean < 2 SD); Stage 3 (n = 30), reversed UA end-diastolic flow; Stage 4 (n = 12), absent or reversed atrial flow in the ductus venosus. In addition, 36 normally grown fetuses were studied for comparison. PI and time-averaged maximum velocity (TAMXV) in the MCA and the anterior cerebral (ACA), pericallosal (PER) and posterior cerebral (PCA) arteries were measured. RESULTS In IUGR fetuses, PI values from all arteries were significantly reduced at Stage 2. At Stages 3 and 4, ACA-PI and PCA-PI did not change further, whereas MCA-PI and PER-PI showed a slight increase. In the ACA, MCA and PER, TAMXV in Stage 2 increased significantly. In Stages 3 and 4, ACA and PER-TAMXV remained unchanged, whereas MCA-TAMXV showed a slight decrease, mirroring the PI values. PCA-TAMXV values were similar to controls at all stages. CONCLUSION In IUGR fetuses, the brain arteries differ in the magnitude and time sequence of Doppler parameters in relation to systemic hemodynamic adaptation, suggesting the existence of regional brain redistribution processes.

Abstract
OBJECTIVE To estimate changes in umbilical blood flow (UBF) and Doppler indices in pregnancies complicated by twin-to-twin transfusion syndrome (TTS) treated with either laser therapy or amniodrainage, and to evaluate the influence of the presence of hemodynamic deterioration prior to therapy, as determined by the Quintero stages of severity. METHODS Forty-eight cases of TTS were included, and further classified into severity Stages I or II (absence of critically abnormal Dopplers (CAD), n = 22) and Stages III or IV (presence of CAD or hydrops fetalis, n = 26). In Stages I-II, 14 cases were treated with laser and eight with amniodrainage, and in Stages III-IV, 17 were treated with laser and nine with amniodrainage. Differences in the UBF, umbilical artery pulstility index (UA-PI) and ductus venosus pulsatility index (DV-PI) were estimated for both groups of severity before and after both treatments. Eleven normal monochorionic pregnancies were evaluated as controls. RESULTS In recipients, UBF was significantly higher with respect to controls regardless of the stage, while donors had a significant decrease in UBF, but only in Stages III-IV. After laser treatment no changes were observed in fetuses in Stages I-II. In Stages III-IV, recipients showed a significant reduction in the DV-PI (mean DV-PI 1.31 +/- 0.18 vs. 1.05 +/- 0.22; P = 0.005) whereas donors showed a significant increase in the UBF (mean UBF 134 +/- 36 mL/min vs. 195 +/- 25 mL/min; P < 0.001) and in the DV-PI (mean DV-PI 0.99 +/- 0.26 vs. 1.36 +/- 0.42; P = 0.002), and a reduction in the UA-PI (mean UA-PI 1.86 +/- 0.41 vs. 1.58 +/- 0.30; P = 0.01). After amniodrainage only donor fetuses in Stages III-IV showed an increase in UA-PI (mean UA-PI 1.54 +/- 0.35 vs. 1.72 +/- 0.40; P = 0.015). No other changes were observed in any of the parameters studied. CONCLUSION Laser therapy induces consistent hemodynamic variations in TTS mainly manifested in Stages III-IV.

Abstract
OBJECTIVE To determine whether a modified myocardial performance index (Mod-MPI) involving assessment of the movements (clicks) of the mitral valve (MV) and aortic valve (AV), improves intra- and interobserver agreement as compared to the previously reported method for MPI estimation. METHODS The Mod-MPI was recorded by two experienced operators in the left cardiac chambers of 25 normally grown fetuses using pulsed Doppler ultrasonography. The isovolumetric contraction time (ICT) was measured from the closure of the MV to the opening of the AV, the ejection time (ET) from the opening to the closure of the AV, and the isovolumetric relaxation time (IRT) from the closure of the AV to the opening of the MV. The Mod-MPI was calculated as (ICT + IRT)/ET. In addition, the MPI was estimated without using the valve clicks (F-MPI) as previously described. Intra- and interobserver agreement were then analyzed for both modalities. RESULTS There was a significantly lower intra- and inter-observer variability in the estimation of all time periods with the Mod-MPI than with the F-MPI (ICT: intra-observer, 9.9% vs. 13.9%; interobserver 9.9% vs. 15.6%; IRT: intraobserver, 9.9% vs. 14.8%; interobserver 10.4% vs. 18.3%; and ET: intraobserver, 4.5% vs. 6.1%; interobserver 2.8% vs. 5.2%, respectively). Intraclass correlation coefficient (IntraCC) for the Mod-MPI was 0.8 (95% confidence interval (95% CI), 0.56-0.9) and for the F-MPI, the IntraCC was 0.62 (95% CI, 0.26-0.84); P = 0.01. Agreement between observers using the Mod-MPI showed a mean difference of 0.0 with 95% limits of agreement (LA) -0.09 (95% CI, -0.1 to -0.075) to 0.09 (95% CI, 0.075-0.1) and for the F-MPI the mean difference was -0.01 with 95% LA -0.26 (95% CI, -0.3 to -0.22) to 0.25 (95% CI, 0.21-0.29). CONCLUSION Calculation of the Mod-MPI based on Doppler echoes of the MV and AV clicks is associated with a lower variation and better inter- and intraobserver agreement than the previously used method for fetal cardiac evaluation.

Abstract
OBJECTIVE To evaluate the rate of spontaneous healing in human fetal membranes after fetoscopy. STUDY DESIGN Membranes from patients that had undergone fetoscopic interventions and delivered in one of the two treatment centers were included in the study. The membranes were examined macroscopically for any remaining defects and if present, the size of the defect in chorion and amnion was measured. Subsequently, the defect was excised and stained with HE for histological evaluation. Additional immunohistochemical staining was performed with Ki-67, cytokeratin and vimentin. The proliferation index (percentage of proliferating cells) was calculated in amnion and chorion. RESULTS Nineteen membrane defects were included in the study. The median time interval between invasive procedures and delivery was 60 days (range 3-112). All fetoscopic defects (n=19) could be identified in the gestational sac and in none spontaneous closure had occurred. Proliferation indices as measured by inmunohistochemistry were very low (median 2.8%, range 0-7%) in the chorion and 0% in the amnion. CONCLUSION No evidence of spontaneous membrane healing was found after fetoscopic procedures, suggesting that the membrane defect normally persists until delivery. Absence of amniotic fluid leakage after invasive procedures may be based on mechanisms other than histologic membrane repair.

Abstract
OBJECTIVE To evaluate the impact of ultrasound cervical length measurement on duration of hospital stay in patients admitted for threatened preterm labor. STUDY DESIGN This was a prospective, comparative study in 294 patients with threatened preterm labor in three hospitalization units (Units A, B and C). In the first phase of the study (observational), cervical length was measured by transvaginal ultrasound, but managing physicians were blinded to the results. In the second phase (interventional), physicians from Unit A remained blinded to cervical length information, but Units B and C incorporated these data into their clinical management protocols. Early discharge was contemplated if the cervix measured 25 mm or more on admission (Unit B) or no changes were observed over 48 h (Unit C). Duration of hospital stay and delivery rates within 7 days and before 37 weeks' gestation were recorded. RESULTS Hospital stay was significantly reduced in Units B and C in the interventional phase, while no changes were observed in Unit A. Delivery rates within 7 days and before 37 weeks' gestation were similar in the three units during the two stages of the study. CONCLUSION Routine use of ultrasound cervical length assessment in patients admitted with threatened preterm labor may reduce the duration of hospital stay without increasing the rate of preterm births. These data should be confirmed by means of an appropriately designed randomized clinical trial.

Abstract
OBJECTIVE To assess the incidence of parenchymal lesions on early and late neonatal brain scans and its association with the presence or absence of intermittent absent or reversed end-diastolic umbilical artery flow velocity (A/REDV) in monochorionic twins complicated by selective intrauterine growth restriction (IUGR), as compared to dichorionic twins and monochorionic twins without selective IUGR. METHODS This was a prospective cohort study involving 42 monochorionic twins diagnosed with selective IUGR and managed expectantly. The presence or absence of intermittent A/REDV was recorded in all cases. This study group was compared to dichorionic twins (n = 29) and monochorionic twins without selective IUGR (n = 32) delivered at 26-34 weeks during the study period. All infants underwent an early neonatal brain scan (at or before the fourth day of postnatal life) and at least one follow-up scan during the first 28 days of postnatal life. Perinatal outcome and the incidence of neurological damage were compared between the study groups. RESULTS The incidence of intrauterine fetal death (IUD) and periventricular leukomalacia was significantly increased in monochorionic twins complicated with selective IUGR, as compared with the other study groups. Intermittent A/REDV was observed in 22/42 (52.4%) twin pairs, and was always present in the growth-restricted twin. The incidence of IUD (overall 9/44 (20.5%) vs. 0/40, P < 0.001; smaller twin 6/22 (27.3%) vs. 0/20, P < 0.05) and parenchymal brain damage (overall 7/35 (20.0%) vs. 2/40 (5.0%), P = 0.07; larger twin 7/19 (36.8%) vs. 1/20 (5.0%), P < 0.05) was significantly higher in pregnancies with intermittent A/REDV than in those without intermittent A/REDV. Brain damage usually occurred in the larger twin, irrespective of whether the smaller twin was liveborn or not. CONCLUSIONS The presence of intermittent A/REDV in monochorionic twins with selective IUGR identifies a subgroup with an elevated risk of intrauterine demise of the smaller twin and neurological damage in the larger twin; this latter finding is not restricted to cases with IUD of the cotwin.

Abstract
OBJECTIVE To evaluate the incidence and clinical relevance of intermittent absent and/or reversed diastolic flow on umbilical artery Doppler in different groups of monochorionic twin pregnancies. METHODS This was a prospective study involving three groups of monochorionic pregnancies: Group 1: controls followed fortnightly from the first trimester (n = 80); Group 2: cases with selective intrauterine growth restriction (n = 40); and Group 3: cases with severe twin-twin transfusion syndrome (n = 50). The presence and persistence over time of intermittent absent and/or reversed end-diastolic flow on umbilical artery Doppler was recorded. Placentas were examined and placental sharing and the presence of large arterioarterial anastomoses (AAA) was assessed. Perinatal outcome was recorded in all cases. RESULTS Intermittent absent and/or reversed diastolic flow was present in 5% (4/80) of cases in Group 1, 45% (18/40) in Group 2 and 2% (1/50) in Group 3 (P < 0.0001, Group 2 vs. 1 and 3). Placental examination was performed in 76.4% (130/170) of cases and sharing was 58% for Group 1, 81% for Group 2 and 73% for Group 3 (P < 0.0001, Groups 2 and 3 vs. 1). Large AAA were identified in all examined cases with intermittent flow (18/18) and in 3.6% (4/112) of those without. The in-utero mortality rate was 0% in Group 1 and in Group 2 fetuses without intermittent flow. However, it was 19.4% in Group 2 cases with intermittent diastolic flow. CONCLUSIONS Intermittent absent and/or reversed end-diastolic flow may be considered to be a characteristic sign of monochorionic pregnancy, and seems to result from the existence of large AAA. Its incidence is significantly increased in the context of selective intrauterine growth restriction, indicating a high risk for poor pregnancy outcome in these cases.

Abstract
The Consensus Statement on Emergency Contraception recommends the collection of data within each country in order to facilitate the use of emergency contraception; this has led us to design a prospective observational study with a view to identifying the reality in Spain regarding emergency contraception. We have conducted a national observational study including 4390 cases of requests for the prescription of emergency contraception in the entire Spanish territory, collected by means of a questionnaire completed by the person prescribing the emergency contraception between April and December 2002. The mean age of the women requesting emergency contraception was 23 years, with 35.1% of these being adolescents and 71% of them under the age of 24 years. Of the applicants, 40% reported that they were students and 31.8% were working. The educational level of studies was medium or higher. Emergency contraception had previously been used by 19.8% of the women and, of these, 75% used it on a single occasion. The main reason put forward for requesting emergency contraception was condom breakage (68.7%), followed by the failure to use any contraceptive measures whatsoever (15.4%). The Spanish women requesting emergency contraception are young students and resort to this method on one occasion.

Abstract
OBJECTIVE To evaluate results of a prospective study of pregnancies in which early amniocentesis with the filtration technique was performed at 10-13 weeks' gestation (mean 12.3 weeks' gestation). METHODS 123 singleton pregnancies in which early amniocentesis with the modified filtration technique was performed at 10-13 weeks' gestation (mean 12.3 weeks' gestation). The amniotic fluid was aspirated into the syringe and reinjected through the filter. RESULTS All the procedures were performed successfully by a single needle insertion. Neither dry taps nor filtration failures occurred. The mean time of amniocentesis was 4.02 min (95% confidence interval, 3 min and 36 s to 4 min and 18 s). The karyotyping success rate was 99.2%. Temporary amniotic fluid leakage occurred in three women (2.4%). There were 110 (89.4%) live births. Two cases of stillbirth occurred at week 38 and week 40. Two unintended losses occurred within three weeks after sampling (1.62%). Another additional unintended fetal death was notified at the 20-week screening ultrasonography. The total fetal-loss rate was 10.6%. In one case, talipes equinovarus was detected at the 20-week screening ultrasound study. CONCLUSIONS Further studies are needed to determine the risk of amniotic leakage and its relation to duration of the procedure in patients undergoing early amnifiltration.

Abstract
OBJECTIVE To evaluate the impact of fetoscopic laser coagulation of placental anastomoses in severe twin-twin transfusion syndrome on fetal Doppler indices and umbilical vein blood flow volume as calculated with Doppler and two-dimensional ultrasound. METHODS Thirty-two cases of second-trimester severe twin-twin transfusion undergoing laser therapy were examined with serial ultrasound before and 1, 3 and 5 days after therapy. Pulsatility indices in the umbilical artery and ductus venosus were measured. Blood volume flow at the level of the intra-abdominal umbilical vein was calculated by means of Doppler and two-dimensional ultrasound. The development of hydropic signs in donors was recorded. Perinatal outcome in terms of neonatal survival was recorded for all cases. RESULTS In recipients, ductus venosus pulsatility index decreased progressively after therapy and, by day 5, median pulsatility index was significantly lower than that before therapy (0.97 vs. 0.82, P < 0.0001). Umbilical vein blood flow volume in recipient twins showed no significant variations before and after laser. In donors, umbilical artery pulsatility index decreased significantly by the first day following therapy (2.1 vs. 1.6, P < 0.0001). Previously absent or reverse umbilical end-diastolic flow reappeared after therapy in 46% (7/15) of donors. Ductus venosus pulsatility index in donors increased significantly by day 1 after therapy (0.99 vs. 1.35, P < 0.0001) but, over days 3 and 5, it returned towards preoperative values. Umbilical vein flow volume measurements (mL/min/kg) in the donor increased by approximately 50% the day after treatment (151 vs. 232, P < 0.0001) and remained elevated. Umbilical vein flow volume before laser therapy was significantly lower in donors compared to recipients (151 vs. 260, P < 0.0001), but the difference was non-significant after treatment (240 vs. 267). One or more hydropic signs developed in eight (25%) donors during the 5 days' observation after therapy. CONCLUSIONS Laser therapy induced important changes in fetal hemodynamic parameters, resulting in a reversion of the disturbances associated with severe twin-twin transfusion syndrome. The recipient twin showed a progressive improvement of previous signs of right cardiac overload. The donor experienced a substantial increase in umbilical vein blood volume flow accompanied by a transitory state of relative right overload, which may explain the development of transient hydropic signs in a proportion of donors.

Abstract
OBJECTIVE To evaluate the incidence, characteristics, and impact on perinatal outcome of the development of hydropic signs in the donor fetus after laser coagulation for severe twin-twin transfusion syndrome in the second trimester. METHODS Forty cases of second-trimester severe twin-twin transfusion underwent fetoscopic laser coagulation of placental anastomoses and were followed up with serial ultrasound up to 14 days after therapy. Ultrasound scans were performed just before, and on days 1, 3, 5 and 14 after therapy, and fetuses were monitored for the presence of hydropic signs (skin edema, pleural effusion, ascites and pericardial effusion). Response to therapy and perinatal outcome in terms of neonatal survival were recorded for all cases. RESULTS Four recipients (10%) and three donors (7.5%) died over the first 72 h after therapy. During the study period, two recipients (5.5%) developed frank hydrops fetalis, and eventually died in utero. Ten donors (27.0%) developed one or more hydropic signs. In nine (90%), signs were mild or moderate and transient (mean, 3.2 days), while in one case hydrops worsened and the fetus eventually died. No donors with transient hydrops died in utero, and two died postnatally due to extreme prematurity. Gestational age at procedure and deepest amniotic fluid vertical pocket were similar between hydropic and non-hydropic donors. Discrepancy in estimated fetal weight at procedure was significantly lower in donors developing hydrops (9.6 (SD, 6.4) vs. 17.8 (14.4)%,P = 0.018). In pregnancies with hydropic donors, gestational age at delivery (33.1 (3.4) vs. 29.7 (3.5) weeks,P = 0.015) and birth weight for recipient (2392 (423) vs. 1631 (576) g, P < 0.001) and donor (1908 (774) vs. 1281 (583) g,P = 0.021) were significantly higher. The development of transient hydrops had no influence on neonatal survival at 28 days nor on the rate of clinical resolution of intertwin transfusion. CONCLUSIONS Transient hydropic signs may develop in a proportion of donor fetuses after laser coagulation for severe twin-twin transfusion syndrome. This phenomenon is normally not associated with a poor prognosis, and possibly indicates an hemodynamic adaptation response following interruption of the transfusion process.

Abstract
OBJECTIVE Changes in hemostatic system were evaluated in healthy pregnant women. METHODS Blood was sampled in the 1st, 2nd and 3rd trimesters of gestation, during delivery and 3 days postpartum and plasma factors were measured using commercial tests. RESULTS Thrombin-antithrombin III complexes, fibrinopeptide A and D-dimer were higher during pregnancy. The endothelial cell markers, fibronectin and tissue factor, remained within the normal reference values in the healthy nonpregnant population. This result suggests no endothelial injury and shows no activation of extrinsic coagulation pathway during pregnancy. The balance coagulation/fibrinolysy is maintained during pregnancy and delivery, as shown by the ratio fibrinopeptide A/D-dimer, however, a tendency towards coagulation process is developed in the early puerperium.

Abstract
BACKGROUND To investigate sociodemographic factors and smoking habit characteristics associated with spontaneous smoking cessation during pregnancy. DESIGN SUBJECTS AND METHODS Cross-sectional study including 726 pregnant smoking women who attended the antenatal clinic of the Vall d'Hebron University Hospital in Barcelona between July and December 1997 and who agreed to participate were studied. Information was obtained by a structured questionnaire which included items on age, educational level, marital status, previous and current smoking habit, partner smoking habit and partner's attitude towards the smoking habit of the pregnant woman. RESULTS At the first antenatal visit, 19.7% of women had given up smoking spontaneously. Light smokers (between 1 and 9 daily cigarettes; OR = 4.74) or moderate smokers (between 10 and 19 daily cigarettes; OR = 2.20) were more likely to stop smoking compared to heavy smokers (more than 20 daily cigarettes). If the partner did not smoke, smoking cessation was more likely among pregnant women (OR = 1.78). At the first antenatal visit, among those women who carried on smoking during pregnancy, there was a significative reduction in cigarette consumption of about half the usual daily number of cigarettes smoked. CONCLUSIONS One out of five pregnant women give up smoking spontaneously during pregnancy from the moment they know they were pregnant until the first antenatal visit. Women who are less likely to stop smoking during pregnancy are those who smoke a larger number of cigarettes. Family environment is an important influential factor in the smoking habit of the pregnant woman.

Abstract
Granada medium was evaluated for the detection of group B streptococci (GBS) in vaginal and rectal swabs compared with selective Columbia blood agar and selective Lim broth. From May 1996 to March 1998, 702 pregnant women (35 to 37 weeks of gestation) participated in this three-phase study; 103 (14.7%) of these women carried GBS. In the first phase of the experiment (n = 273 women), vaginorectal specimens were collected on the same swab; the sensitivities of Granada tube, selective Columbia blood agar, and Lim broth were 31.4, 94.3, and 74.3%, respectively. In the second and third phases (n = 429 women), vaginal and rectal specimens were collected separately; the sensitivities of Granada plate, selective Columbia blood agar, and Lim broth (subcultured at 4 h on selective Columbia agar in the second phase and at 18 to 24 h in Granada plate in the third phase) were 91.1, 83.9, and 75%, respectively, in the second phase and 88.5, 90.4, and 63.5%, respectively, in the third phase. There were no statistically significant differences in GBS recovery between the Granada agar plate and selective Columbia blood agar, but the Granada plate provided a clear advantage; the characteristic red-orange colonies produced overnight by GBS can be identified by the naked eye and is so specific that further identification is unnecessary. The use of the Granada tube and Lim broth did not result in increased isolation of GBS. In conclusion, the Granada agar plate is highly sensitive for detecting GBS in vaginal and rectal swabs from pregnant women and can provide results in 18 to 24 h.

Abstract
OBJECTIVE Our goal was to compare sensitivity, specificity, and predictive values of glucose and cytokines [interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor (TNF)] in amniotic fluid (AF) to detect an AF-positive culture. METHODS Amniocentesis was performed on 113 patients with preterm labour (PTL) and intact membranes. Fluid was cultured for aerobic and anaerobic bacteria, and for mycoplasmas. AF analysis included cytokines and glucose determinations. RESULTS The prevalence of positive AF cultures was 11.5% (13/113). Anaerobic bacteria were isolated in 9 patients (69.2%). The glucose <16 mg/dl and cytokines values; IL-1 >640 pg/ml, IL-6 >55,000 pg/ml, IL-8 >1,000 pg/ml, TNF >672 pg/ml, were significantly correlated (P < 0.01) with AF culture result. Glucose had a sensitivity of 69.2% and a specificity of 96% for the prediction of positive AF culture. The sensitivity and specificity of the cytokines ranged from 61.5-53.4% and 79.8-8.99%, respectively. CONCLUSIONS In the diagnosis of the AF-positive culture, glucose <16 mg/dl is more sensitive than cytokines.

Abstract
To assess coagulation activation and endothelial cell injury in normotensive and pre-eclamptic pregnant women, a comparison was made of plasma levels of tissue factor, fibronectin, fibrinopeptide A and D-dimer. Samples were taken from 50 nonpregnant women, 40 normotensive pregnant women in the third trimester and 27 women with pre-eclampsia after diagnosis and before treatment. High levels of fibrinopeptide A and D-dimer were found in pre-eclamptic women. Moreover, the ratio fibrinopeptide A:D-dimer was much greater in the pre-eclampsia group than in normotensive pregnant women. The levels of fibronectin and tissue factor were also higher in the pre-eclampsia group. The increase of tissue factor levels suggests an alteration of the extrinsic coagulation pathway in pre-eclampsia. The increase of fibrinopeptide A:D-dimer ratio shows that the activation of coagulation is associated with a relative hypofibrinolysis in pre-eclampsia.

Abstract
OBJECTIVE To investigate the expression of the P450c17 gene in postmenopausal human ovaries compared with normal cycling ovaries. DESIGN Prospective nonrandomized clinical research study. SETTING Servei de Medicina Reproductiva and Centre d'Investigacions en Bioquimica i Biologia Molecular, Hospitals Vall d'Hebron, Barcelona, Spain. PATIENT(S) Six premenopausal women and four postmenopausal women undergoing bilateral oophorectomy for nonovarian gynecologic disease. INTERVENTION(S) Extraction of 10 mL of peripheral venous blood for hormone measurements. Extraction of RNA from surgically removed ovaries for Northern blot, ribonuclease protection, and reverse transcriptase polymerase chain reaction Southern blot assays. MAIN OUTCOME MEASURE(S) Definition of the reproductive cycle state of each patient and determination of the level of P450c17 gene expression in all samples with the use of the semiquantitative reverse transcriptase polymerase chain reaction Southern blot assay. RESULT(S) P450c17 messenger RNA levels in postmenopausal ovaries varied considerably between samples. Although the levels were similar to those detected in the early follicular phase, one of the samples had levels as high as those observed in the late follicular phase. CONCLUSION(S) Although the degree varied from one sample to another, all the postmenopausal ovaries studied expressed the P450c17 gene at the messenger RNA level. In a sample from a patient with endometrial adenocarcinoma, the level was as high as the levels observed in the late follicular phase.

Abstract
The changes in coagulation and fibrinolysis parameters during pregnancy, delivery and 3 days after delivery were evaluated in normotensive and gestational diabetes pregnant women. Normal pregnant women (n = 60) and pregnant women with gestational diabetes (n = 15) formed the study population. Coagulation and fibrinolysis parameters were estimated using commercial tests. Antithrombin III, thrombin-antithrombin III complexes, heparin cofactor II, protein C, protein S, tissue plasminogen activator, (t-PA) D-dimer and plasminogen activator inhibitor (PAI-1 and PAI-2) activities in normal and gestational diabetes pregnancies were determined. Thrombin-antithrombin III complexes increased and coagulation inhibitors decreased in gestational diabetes. Plasminogen activator inhibitors remained unchanged and t-PA levels increased in gestational diabetes.
