Abstract
OBJECTIVES In fetuses with isolated left-sided congenital diaphragmatic hernia (LCDH), prenatal detection of severe pulmonary hypoplasia is important, as fetal therapy can improve survival. Cases with mild or moderate lung hypoplasia still carry a considerable risk of mortality and morbidity, but there has been less interest in the accurate prediction of outcome in these cases. In this study of fetuses with mild or moderate isolated LCDH, we aimed to investigate: (1) the association between intrapulmonary artery (IPA) Doppler findings and mortality at discharge; (2) whether adding IPA Doppler findings improves the prediction of mortality based on lung size and liver herniation; and (3) the association between IPA Doppler findings and early neonatal morbidity. METHODS This was a retrospective study of all consecutive fetuses assessed at the BCNatal and UZ Leuven hospitals between 2008 and 2020 with a prenatal diagnosis of isolated, non-severe LCDH, defined as observed-to-expected lung-to-head ratio (o/e-LHR) > 25%, that were managed expectantly during pregnancy followed by standardized neonatal management. An additional inclusion criterion was the availability of IPA Doppler measurements. The primary outcome was the association between IPA Doppler findings and mortality at discharge. Other predictors included o/e-LHR, liver herniation and gestational age at birth. Secondary outcomes were the association between IPA Doppler findings and the presence of pulmonary hypertension (PHT), need for supplemental oxygen at discharge and need for extracorporeal membrane oxygenation. IPA pulsatility index (PI) values were converted into Z-scores. Logistic regression analysis was performed to investigate the associations between predictor variables and outcome, and the best model was chosen based on the Nagelkerke R2 . RESULTS Observations for 70 non-severe LCDH cases were available. Fifty-four (77%) fetuses survived until discharge. On logistic regression analysis, higher IPA-PI was associated with an increased risk of mortality (odds ratio (OR), 3.96 (95% CI, 1.62-9.70)), independently of o/e-LHR (OR, 0.87 (95% CI, 0.79-0.97)). An IPA-PI Z-score cut-off of 1.8 predicted mortality with a detection rate of 69% and specificity of 93%. Adding IPA-PI to o/e-LHR improved significantly the model's performance (Nagelkerke R2 , 46% for o/e-LHR + IPA-PI vs 28% for o/e-LHR (P < 0.002)), with a detection rate of 81% at a 10% false-positive rate. IPA-PI was associated with PHT (OR, 2.20 (95% CI, 1.01-4.59)) and need for oxygen supplementation at discharge (OR, 1.90 (95% CI, 1.10-3.40)), independently of lung size. CONCLUSIONS In fetuses with mild or moderate LCDH, IPA-PI was associated with mortality and morbidity, independently of lung size. A model combining o/e-LHR with IPA-PI identified up to four in five cases that eventually died, despite being considered to have non-severe pulmonary hypoplasia. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE To construct nomograms for fetal cardiac, ventricular and atrial relative size and geometry parameters from 18 to 41 weeks' gestation using a low-risk population of singleton pregnancies. METHODS This was a prospective cohort study of 602 low-risk singleton pregnancies undergoing comprehensive fetal echocardiography, from 18 to 41 weeks of gestation, to assess fetal cardiac, atrial and ventricular relative size and sphericity, ventricular dominance, wall asymmetry and relative wall thickness. Intra- and interobserver measurement reproducibility was evaluated using intraclass correlation coefficients (ICC). In order to construct reference ranges across pregnancy, parametric regressions were tested to model each measurement against gestational age and estimated fetal weight. The measurements evaluated were: cardiothoracic ratio; atrial-to-heart area ratios; ventricular-to-heart area ratios; cardiac, ventricular and atrial sphericity indices; right-to-left basal and midventricular ratios; septal-to-free wall thickness ratios; and relative wall thickness. RESULTS Fetal cardiac, ventricular and atrial morphometry for assessing relative size and geometry could be successfully performed in > 95% of the population, with moderate-to-excellent interobserver reproducibility (ICC, 0.623-0.907) and good-to-excellent intraobserver reproducibility (ICC, 0.787-0.938). Cardiothoracic ratio and ventricular right-to-left ratio showed a modest increase throughout gestation. Atrial-to-heart and ventricular-to-heart area ratios, atrial sphericity indices and septal-to-free wall thickness ratios were constant with gestational age. Left and right ventricular basal sphericity indices showed a tendency to decrease at the end of gestation, while left and right midventricular sphericity indices tended to decrease in the second trimester. The cardiac sphericity index and left and right relative wall thickness showed a modest decrease with gestational age. Nomograms across gestation were constructed for all echocardiographic parameters described. CONCLUSIONS The assessment of cardiac, ventricular and atrial relative size and geometry is feasible and reproducible in the fetus. We provide standardized reference ranges for these parameters throughout gestation, enabling the accurate assessment of cardiac remodeling patterns during fetal life. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES Fetal cardiac function can be evaluated using a variety of parameters. Among these, cardiac cycle time-related parameters, such as filling time fraction (FTF) and ejection time fraction (ETF), are promising but rarely studied. We aimed to report the feasibility and reproducibility of fetal FTF and ETF measurements using pulsed-wave Doppler, to provide reference ranges for fetal FTF and ETF, after evaluating their relationship with heart rate (HR), gestational age (GA) and estimated fetal weight (EFW), and to evaluate their potential clinical utility in selected fetal conditions. METHODS This study included a low-risk prospective cohort of singleton pregnancies and a high-risk population of fetuses with severe twin-twin transfusion syndrome (TTTS), aortic stenosis (AoS) or aortic coarctation (CoA), from 18 to 41 weeks' gestation. Left ventricular (LV) and right ventricular inflow and outflow pulsed-wave Doppler signals were analyzed, using valve clicks as landmarks. FTF was calculated as: (filling time/cycle time) × 100. ETF was calculated as: (ejection time/cycle time) × 100. Intraclass correlation coefficients (ICC) were used to evaluate the intra- and interobserver reproducibility of FTF and ETF measurements in low-risk fetuses. The relationships of FTF and ETF with HR, GA and EFW were evaluated using multivariate regression analysis. Reference ranges for FTF and ETF were then constructed using the low-risk population. Z-scores of FTF and ETF in the high-risk fetuses were calculated and analyzed. RESULTS In total, 602 low-risk singleton pregnancies and 54 high-risk fetuses (nine pairs of monochorionic twins with severe TTTS, 16 fetuses with AoS and 20 fetuses with CoA) were included. Adequate Doppler traces for FTF and ETF could be obtained in 95% of low-risk cases. Intraobserver reproducibility was good to excellent (ICC, 0.831-0.905) and interobserver reproducibility was good (ICC, 0.801-0.837) for measurements of all timing parameters analyzed. Multivariate analysis of FTF and ETF in relation to HR, GA and EFW in low-risk fetuses identified HR as the only variable predictive of FTF, while ETF was dependent on both HR and GA. FTF increased with decreasing HR in low-risk fetuses, while ETF showed the opposite behavior, decreasing with decreasing HR. Most recipient twins with severe TTTS showed reduced FTF and preserved ETF. AoS was associated with decreased FTF and increased ETF in the LV, with seemingly different patterns associated with univentricular vs biventricular postnatal outcome. The majority of fetuses with CoA had FTF and ETF within the normal range in both ventricles. CONCLUSIONS Measurement of FTF and ETF using pulsed-wave Doppler is feasible and reproducible in the fetus. The presented reference ranges account for associations of FTF with HR and of ETF with HR and GA. These time fractions are potentially useful for clinical monitoring of cardiac function in severe TTTS, AoS and other fetal conditions overloading the heart. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES Coarctation of the aorta (CoA) is associated with left ventricular (LV) dysfunction in neonates and adults. Cardiac structure and function in fetal CoA and cardiac adaptation to early neonatal life have not been described. We aimed to investigate the presence of cardiovascular structural remodeling and dysfunction in fetuses with CoA and their early postnatal cardiac adaptation. METHODS This was a prospective observational case-control study, conducted between 2011 and 2018 in a single tertiary referral center, of fetuses with CoA and gestational age-matched normal controls. All fetuses/neonates underwent comprehensive echocardiographic evaluation in the third trimester of pregnancy and after birth. Additionally, myocardial microstructure was assessed in one fetal and one neonatal CoA-affected heart specimen, using synchrotron radiation-based X-ray phase-contrast microcomputed tomography and histology, respectively. RESULTS We included 30 fetuses with CoA and 60 gestational age-matched controls. Of these, 20 CoA neonates and 44 controls were also evaluated postnatally. Fetuses with CoA showed significant left-to-right volume redistribution, with right ventricular (RV) size and output dominance and significant geometry alterations with an abnormally elongated LV, compared with controls (LV midventricular sphericity index (median (interquartile range; IQR), 2.4 (2.0-2.7) vs 1.8 (1.7-2.0); P < 0.001). Biventricular function was preserved and no ventricular hypertrophy was observed. Synchrotron tomography and histological assessment revealed normal myocyte organization in the fetal and neonatal specimens, respectively. Postnatally, the LV in CoA cases showed prompt remodeling, becoming more globular (LV midventricular sphericity index (mean ± SD), 1.5 ± 0.3 in CoA vs 1.8 ± 0.2 in controls; P < 0.001) with preserved systolic and normalized output, but altered diastolic, parameters compared with controls (LV inflow peak velocity in early diastole (mean ± SD), 97.8 ± 14.5 vs 56.5 ± 12.9 cm/s; LV inflow peak velocity in atrial contraction (median (IQR), 70.5 (60.1-84.9) vs 47.0 (43.0-55.0) cm/s; LV peak myocardial velocity in atrial contraction (mean ± SD), 5.1 ± 2.6 vs 6.3 ± 2.2 cm/s; P < 0.05). The neonatal RV showed increased longitudinal function in the presence of a patent arterial duct. CONCLUSIONS Our results suggest unique fetal cardiac remodeling in CoA, in which the LV stays smaller from the decreased growth stimulus of reduced volume load. Postnatally, the LV is acutely volume-loaded, resulting in an overall geometry change with higher filling velocities and preserved systolic function. These findings improve our understanding of the evolution of CoA from fetal to neonatal life. Copyright © 2020 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
This research aims to evaluate whether the electroporation of Rhodotorula glutinis fresh biomass improved the subsequent extraction of carotenoids from dry biomass using supercritical CO2 and traditional solvent extraction. Supercritical CO2 extraction yields were low after all treatments assayed. Similarly, solvent extraction of carotenoids from untreated or PEF treated cells that were immediately freeze-dried after the pre-treatment was neither effective (extraction yield < 20% total content). Conversely, PEF-treatment and subsequent intermediate incubation in aqueous buffer for 24 h, followed by freeze-drying and extraction, led to a large improvement with the three solvents assayed (acetone, hexane, ethanol). Ethanol was the most efficient, reaching an extraction yield of 80% of total carotenoid, which represents a recovery of 267 µg/gdw. Torularhodin esters constituted the main carotenoid found in the extracts. This is of great interest, as ethanol is eco-friendly solvent and potential applications of torularhodin range from food to medical purposes.

Abstract
OBJECTIVES Firstly, to describe the outcome of a series of fetuses with Ebstein's anomaly (EA) and, secondly, to study the utility of different second-trimester echocardiographic parameters to predict fetal and neonatal mortality. METHODS 39 fetuses with EA diagnosed between 18 and 28 weeks of gestation were included. Fetal echocardiography included the cardiothoracic ratio (CTR); right atrial (RA) area index; displacement of the tricuspid valve (TV); tricuspid regurgitation; pulmonary artery; and ductus arteriosus flow characteristics. Additionally, 2 novel parameters were obtained: the relative RA area ratio (RA area/cardiac area) and the TV displacement index (TVDI, TV displacement distance/longi-tudinal diameter of the left ventricle). Correlation between the echocardiographic variables and the primary outcome of perinatal mortality or survival at 1 year of life was evaluated. RESULTS From the initial cohort, 8 cases were excluded due to complex congenital heart defects. Termination of pregnancy (TOP) was performed in 15 cases, and fetal death was diagnosed in 3 cases. In the live-born cohort of 13 patients, 4 died in the neonatal period, yielding a perinatal survival rate of 29 and 56%, respectively, after excluding TOP cases. Compared with survivors, nonsurvivors showed a significantly higher CTR (56.7 ± 16.2 vs. 42.6 ± 8.6; p = 0.04), relative RA area ratio (0.39 ± 0.13 vs. 0.25 ± 0.05; p = 0.01), and TVDI (0.62 ± 0.17 vs. 0.44 ± 0.12; p = 0.03) at diagnosis. The best model to predict perinatal mortality was obtained by using a scoring system which included the relative RA area ratio and TVDI (AUC 0.905 [95% CI 0.732-1.000]). CONCLUSIONS Fetuses with a relative RA area ratio ≥0.29 and TVDI ≥0.65 at the second trimester have the highest risk of dying in the perinatal stage.

Abstract
OBJECTIVES Fetal right ventricular (RV) function assessment is challenging due to the RV geometry and limitations of in utero assessment. Postnatally, 2D echocardiographic RV fractional area change (FAC) is used to assess RV global systolic function by calculating the percentage of change in RV area from systole to diastole. Reports on FAC are scarce in prenatal life, and nomograms throughout pregnancy are not available. Our aims were (1) to study prenatal RV FAC feasibility and reproducibility and (2) to construct nomograms for RV FAC and end-diastolic (ED) and end-systolic (ES) RV areas from 18 to 41 weeks of gestation. METHODS Prospective cohort study including 602 low-risk singleton pregnancies undergoing a fetal echocardiography from 18 to 41 weeks of gestation. RV ED and ES areas were measured following standard recommendations for ventricular dimensions and establishing strict landmarks to identify the different phases of the cardiac cycle. RV FAC was calculated as: ([ED area - ES area]/ED area) × 100. RV FAC intra- and inter-observer reproducibility was evaluated in 45 fetuses by calculating the intraclass correlation coefficient (ICC). Parametric regressions were tested to model each parameter against gestational age (GA) and estimated fetal weight (EFW). RESULTS RV areas and FAC were successfully obtained in ∼99% of fetuses with acceptable reproducibility throughout gestation (RV ED area inter-observer ICC [95% CI] 0.96 [0.93-0.98], RV ES area 0.97 [0.94-0.98], and FAC 0.69 [0.44-0.83]). Nomograms were constructed for RV ED and ES areas and FAC. RV areas showed a quadratic and logarithmic increase with GA and EFW, respectively. In contrast, RV FAC showed a slight quadratic decrease throughout gestation (mean RV FAC ranged from 36% at 18 weeks of gestation [10-90th centiles: 25-47%, respectively] to 29% at 41 weeks [10-90th centiles: 18-40%, respectively]). The best models for RV areas and FAC were a second-degree polynomial. CONCLUSIONS RV FAC is a feasible and reproducible parameter to assess RV global systolic function in fetal life. We provide reference ranges adjusted by GA and EFW that can be used as normal references for the assessment of RV function in prenatal conditions.

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
Background Mitochondrial toxicity related to maternal combined antiretroviral treatment (cART) may have an impact on the heart of HIV-exposed uninfected (HEU) fetuses. Our objective was to evaluate fetal cardiovascular and mitochondrial biomarkers in HIV pregnancies. Methods Prospective cohort including 47 HIV-infected and 47 non HIV-infected pregnancies. Fetal echocardiography was performed at 26–32 weeks of pregnancy. Umbilical cord blood and placental tissue were collected to study mitochondrial DNA content (mtDNA) (ratio 12SrRNA/RNAseP) and mitochondrial function (cytochrome c oxidase, COX, enzymatic activity) normalized by mitochondrial content (citrate synthase, CS). Results HEU fetuses showed hypertrophic hearts (left myocardial wall thickness: HIV mean 3.21 mm (SD 0.81) vs. non-HIV 2.72 (0.42), p = 0.012), with signs of systolic and diastolic dysfunction (isovolumic relaxation time: HIV 52.2 ms (8.85) vs. non-HIV 42.5 ms (7.30); p<0.001). Cord blood mitochondrial content was significantly increased in HIV-exposed fetuses (CS activity: HIV 82.9 nmol/min.mg of protein (SD 40.5) vs. non-HIV 56.7 nmol/min.mg of protein (28.4); p = 0.007), with no differences in mtDNA content and COX activity. Both myocardial and mitochondrial mass parameters were significantly associated with zidovudine exposure. Conclusions HEU fetuses showed signs of increased myocardial and mitochondrial mass associated with maternal zidovudine treatment, suggesting a fetal adaptive response to cART toxicity.

Abstract
INTRODUCTION Evidence suggests an excess of long-term mortality due to cardiovascular diseases, second tumours and other causes in patients diagnosed with invasive breast cancer (BC). Our aim was to assess this risk of death in a cohort of patients diagnosed with BC in Girona and Tarragona, northeastern Spain. MATERIALS AND METHODS Using data from the cancer registries in these areas, a population-based cohort study was carried out including all the women diagnosed with BC during 1985-2004 and followed up until December 31st 2014 (N = 10,195). The standardised mortality ratios (SMRs) were calculated for causes other than BC in the cohort at 10 years (periods 1985-1994/1995-2004) and 20 years (period 1985-1994). The impact of competing causes of death in the long-term survival was evaluated through competing risk analysis. RESULTS The SMRs at 10 and 20 years for all-cause mortality, except BC, were 1.21 and 1.22. The main causes of mortality showing statistically significant SMR at 10 years were other tumours (colon, lung, corpus uteri, ovary, and haematological), diabetes mellitus, diseases of the nervous system, cardiovascular diseases (after BC, the second competing cause of death among patients diagnosed > 69 years) and diseases of the kidney. Globally, the 10-year SMR was higher in the first period. After 20 years of follow-up (1985-1994 cohort), there were 48.5 excess deaths per 10,000 patient-years for causes other than BC. CONCLUSIONS Women who did not die from BC at 10 or 20 years after the BC diagnosis had 20% higher risk of dying from other causes than women without BC. This excess risk must be clinically considered during 20 years after the BC diagnosis.

Abstract
OBJECTIVES The purpose of this study was to analyze the relationship between working hours (WHs) and the likelihood of poor self-reported general health (SRGH) in the first data wave from a cohort of immigrant and native workers in Spain. STUDY DESIGN Cross-sectional analyses from a prospective cohort study. METHODS Data were drawn from the first wave of the Platform of Longitudinal Studies on Immigrant Families. The selected sample was composed of 217 immigrant workers and 89 native-born workers. We explored differences by immigrant status and family structure, assessing prevalences and Poisson regression models; an additional analysis explored statistically optimized work hour cut points. RESULTS Highest prevalence of poor SRGH (72.7%) was reported by immigrant, single-parent workers working >40 WH/week. Immigrant single-parent families were more likely to report poor SRGH for three WH categories: ≤20 WH/week (prevalence ratio [PR] = 3.3, 95% confidence interval [CI] 1.6-7.2), >30-≤40 WH/week (PR = 2.8, 95% CI 1.3-6.4), and >40 WH/week (PR = 4.2, 95% CI 1.8-10.1). In two-parent families, immigrants working standard hours (i.e. >30-≤40) and native-born workers in the highest and lowest categories of WHs (i.e. ≤20 and >40) had similar PRs for poor SRGH compared with native-born workers working standard hours. Findings suggested that native-born workers residing in two-parent families were able to work more than 10 h longer per week than immigrant workers before reporting equivalent prevalences of poor SRGH. CONCLUSIONS Differences in the association of WHs and poor SRGH among immigrants in Spain seem to be explained by family structure, which suggests that the influence of WHs on health differentially affects vulnerable groups, such as immigrant workers residing in single-parent families.

Abstract
Background We provide population-based long-term survival indicators of breast cancer patients by quantifying the observed survival, and the probabilities of death due to breast cancer and to other causes by age and tumor stage at diagnosis. Methods We included a total of 10,195 female patients diagnosed before 85 years with invasive primary breast cancer in Girona and Tarragona during the periods 1985–1994 and 1995–2004 and followed-up until December 31st 2014. The survival indicators were estimated at 5, 10, 15 and 20 years of follow-up comparing diagnostic periods. Results Comparing diagnostic periods: I) the probability of death due to other causes did not change; II) the 20-year survival for women diagnosed ≤ 49 years increased 13% (1995–2004 = 68%; 1985–1994:55%), whereas their probability of death due to breast cancer decreased at the same pace (1995–2004 = 29%; 1985–1994 = 42%); III) at 10 years of follow-up, decreases in the probabilities of death due to breast cancer across age groups switched from 11 to 17% resulting in a risk of death reduction of 19% after adjusting by stage. During 1995–2004, the stage-specific 10-year probabilities of death due to breast cancer switched from: 3–6% in stage I, 18–20% in stage II, 34–46% in stage III and surpassed 70% in stage IV beyond 5 years after diagnosis. Conclusions In our study, women diagnosed with breast cancer had higher long-term probability to die from breast cancer than from other causes. The improvements in treatment and the lead-time bias in detecting cancer in an early stage resulted in a reduction of 19% in the risk of death between diagnostic periods.

Abstract
OBJECTIVES To define the pattern of fetal echocardiographic changes associated with isolated pulmonary valve stenosis (PS) and to correlate the echocardiographic findings with neonatal outcome and the need for postnatal pulmonary valvuloplasty within the first 12 months postpartum. METHODS This was a prospective cohort study between January 2009 and October 2015 of 16 fetuses with isolated PS and 48 controls matched by gestational age at ultrasound examination (± 2 weeks) evaluated at the Fetal Cardiology Unit at BCNatal (Barcelona). Standard fetal ultrasound and comprehensive echocardiography, which included cardiovascular morphometric parameters, and systolic and diastolic functional and timing measurements, were performed in all cases. Baseline characteristics and perinatal outcome were retrieved from clinical records. Cases were followed up until 12 months of age, and admission to intensive care unit, days of hospitalization, need for prostaglandins and requirement for postnatal surgery were reviewed. Fetal PS cases were analyzed according to the need for postnatal pulmonary valvuloplasty. RESULTS The study groups were similar in terms of baseline, fetal ultrasound and perinatal characteristics. Median gestational age at diagnosis of PS was 33.4 (range, 20.0-36.5) weeks. Most cases corresponded to mild or moderate PS; only three fetuses had reversed flow in the ductus arteriosus before delivery. Six (37.5%) newborns, including all three with reversed flow in the ductus arteriosus prenatally, required postnatal pulmonary valvuloplasty. Fetuses with PS presented with larger and more globular hearts, with increased myocardial wall thickness in the third trimester. Despite preserved right ventricular (RV) ejection fraction and systolic longitudinal motion, PS cases showed increased right cardiac output and signs of diastolic dysfunction, with higher ductus venosus pulsatility index (0.72 ± 0.32 vs 0.53 ± 0.16, P = 0.004) and tricuspid E/E' ratio (7.52 ± 3.07 vs 5.76 ± 1.79, P = 0.022). In addition, fetuses with PS displayed a compensatory increase in left ventricular (LV) radial and longitudinal motion, as shown by a higher ejection fraction (79.3 ± 8.23% vs 67.6 ± 11.3%, P = 0.003) and mitral annular-plane systolic excursion (5.94 ± 1.38 vs 5.0 ± 1.22 mm, P = 0.035). Finally, fetuses requiring postnatal pulmonary valvuloplasty showed a different pattern of echocardiographic findings from those not requiring valvuloplasty, with a significantly smaller RV and pulmonary valve diameter, reduced tricuspid annular-plane systolic excursion (5.08 ± 1.59 vs 8.07 ± 1.93 mm, P = 0.028), increased LV cardiac output (340 ± 16 vs 176 ± 44 mL/min/kg, P = 0.003) and more pronounced signs of LV diastolic dysfunction (mitral E' velocity, 5.78 ± 0.90 vs 8.16 ± 1.58 cm/s, P = 0.008). CONCLUSIONS Fetuses with PS present with more hypertrophic, larger and more globular hearts in the third trimester of pregnancy, associated with a higher right cardiac output and impaired biventricular relaxation. In addition, signs of increased LV contraction were observed. Our data suggest that RV and LV functional parameters could be useful for predicting the need for postnatal pulmonary valvuloplasty.

Abstract
OBJECTIVE Fetal aortic valvuloplasty (FAV) may avoid progression of critical aortic stenosis (CAS) to hypoplastic left ventricle, improving the options for biventricular circulation (BVC). We describe the results of FAV in 2 referral centers in Spain. METHODS We analyzed all FAVs performed in the period 2007-2015. The selection of candidates, the technique, and postnatal management were made following an agreed protocol. A descriptive analysis of survival, type of circulation after birth, and complications was made, considering all deaths in the first 48 h after FAV as FAV-related. RESULTS FAV was performed in 28 fetuses at a median gestational age (GA) of 23 weeks (range, 20-32). FAV was technically successful in 22 (78.6%), of whom 11 were born alive and with intention to treat. Eight (72.7%) resulted in BVC and 3 (27.3%) in univentricular circulation. The rate of FAV-related deaths was 32%. These patients underwent FAV earlier than live-born fetuses (median GA at FAV 22 weeks [range, 20.0-25.0] vs. 24.5 weeks [range, 21.0-32.0], respectively, p = 0.031). CONCLUSIONS A significant proportion of fetuses with CAS who undergo technically successful FAV have BVC postnatally. However, FAV implies a high risk of fetal death, which highly depends on the GA at which this intervention is required.

Abstract
OBJECTIVES To determine the longitudinal behavior of fetal biometric measures and cerebroplacental hemodynamics throughout gestation in fetuses with congenital heart disease (CHD). METHODS Fetal biometry and Doppler hemodynamics (uterine artery (UtA), umbilical artery (UA) and fetal middle cerebral artery (MCA)) were measured serially in a cohort of consecutive fetuses diagnosed with CHD. Evaluations were made at various time points, from diagnosis (20-25 weeks) to delivery, with at least two measurements per fetus that were at least 2 weeks apart. Fetuses were classified into three groups according to the pattern of blood supply to the brain (placental vs systemic) that would be expected on the basis of the type of CHD. All parameters were transformed into Z-scores. A linear mixed model to analyze repeated measurements was constructed for each parameter to assess its behavior throughout gestation. RESULTS Four hundred and forty-four ultrasound examinations were performed in 119 CHD fetuses, with a median of two measurements per fetus. The fetuses presented a small head at diagnosis (biparietal diameter (BPD) Z-score, -1.32 ± 0.99; head circumference (HC) Z-score, -0.79 ± 1.02), which remained small throughout gestation. UtA and UA pulsatility indices (PI) showed a significant increase towards the end of pregnancy, whereas no significant changes were observed in MCA-PI or cerebroplacental ratio (CPR) with gestational age. Both MCA and CPR presented significant differences in longitudinal behavior between CHD groups, while BPD and HC did not. CONCLUSIONS CHD fetuses have a relatively small head from the second trimester of pregnancy, regardless of the type of CHD anomaly, and increasing resistance in the UtA and UA as pregnancy progresses, suggestive of increasing degree of placental impairment. Our findings indicate the early onset of mechanisms that could lead to poorer neurodevelopment later in life. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVES Fetuses with congenital heart disease (CHD) show evidence of abnormal brain development before birth, which is thought to contribute to adverse neurodevelopment during childhood. Our aim was to evaluate whether brain development in late pregnancy can be predicted by fetal brain Doppler, head biometry and the clinical form of CHD at the time of diagnosis. METHODS This was a prospective cohort study including 58 fetuses with CHD, diagnosed at 20-24 weeks' gestation, and 58 normal control fetuses. At the time of diagnosis, we recorded fetal head circumference (HC), biparietal diameter, middle cerebral artery pulsatility index (MCA-PI), cerebroplacental ratio (CPR) and brain perfusion by fractional moving blood volume. We classified cases into one of two clinical types defined by the expected levels (high or low) of placental (well-oxygenated) blood perfusion, according to the anatomical defect. All fetuses underwent subsequent 3T-magnetic resonance imaging (MRI) at 36-38 weeks' gestation. RESULTS Abnormal prenatal brain development was defined by a composite score including any of the following findings on MRI: total brain volume < 10(th) centile, parietoccipital or cingulate fissure depth < 10(th) centile or abnormal metabolic profile in the frontal lobe. Logistic regression analysis demonstrated that MCA-PI (odds ratio (OR), 12.7; P = 0.01), CPR (OR, 8.7; P = 0.02) and HC (OR, 6.2; P = 0.02) were independent predictors of abnormal neurodevelopment; however, the clinical type of CHD was not. CONCLUSIONS Fetal brain Doppler and head biometry at the time of CHD diagnosis are independent predictors of abnormal brain development at birth, and could be used in future algorithms to improve counseling and targeted interventions.

Abstract
Objectives: We evaluated the hypothesis that in fetuses with congenital heart disease (CHD) there is a correlation between the expected pattern of in utero brain blood supply and the severity of neurodevelopmental impairment. Methods: A total of 58 fetuses with CHD and 58 controls underwent a Doppler ultrasound and fetal MRI at 36-38 weeks. Fetuses with CHD were divided into two functional classes: class A with an expected severe reduction in oxygenated brain blood supply (left outflow tract obstruction and transposition of great vessels) and class B with theoretically near-normal or mildly impaired oxygenated brain blood supply (other CHD). Head biometry and cerebroplacental Doppler were assessed by ultrasound, and brain volumetry, cortical development and metabolism by MRI. Results: Both class A and B CHD fetuses had significant differences in head biometry, brain perfusion, cortical development and brain metabolism compared with controls. However, there was a significant linear tendency for head biometry, cerebral Doppler, volumes, cortical sulcation and metabolic ratios across the three clinical groups, with signs of more severe brain alterations in type A CHD fetuses. Conclusions: All fetuses with CHD showed significant brain developmental changes, but differences were more pronounced in CHD associated with an expected severe reduction in oxygenated blood supply to the brain.

Abstract
Introduction: Recent studies have reported variations of up to 30% between different ultrasound machines for tissue Doppler imaging (TDI), a problem that can significantly impact clinical diagnosis, patient management and research studies. The objective of this study was to assess repeatability and agreement between fetal myocardial peak velocities evaluated by TDI with two different ultrasound systems. Materials and Methods: Systolic (S'), early (E') and late (A') diastolic myocardial peak velocities at mitral and tricuspid annuli as well as at the basal septum were evaluated by spectral TDI in 150 fetuses using two different ultrasound systems: Siemens Antares (Siemens Medical Systems, Malvern, Pa., USA) and Vivid Q (General Electric Healthcare, Horten, Norway). A method comparison study was performed, calculating intraclass correlation coefficients (ICC), and agreement was assessed by Bland-Altman plots. Results: Annular peak velocities showed lower values when measured by Vivid Q compared to values measured by Siemens Antares. ICC ranged from 0.07 (septal S') to 0.33 (right A'), showing very poor repeatability for clinical application. Agreement between the two systems was also poor, with high coefficients of variation for all measurements. Conclusions: Fetal annular peak velocities obtained with different ultrasound systems are not directly comparable. This is consistent with previous data in adults and warrants the need of system-specific reference values, suggesting that the same ultrasound machine should be used for longitudinal follow-up.

Abstract
OBJECTIVES To evaluate the associations between congenital heart disease (CHD) and head biometry and cerebrovascular blood flow dynamics at the time of diagnosis of CHD in the second trimester of pregnancy. METHODS This was a study of 95 consecutive fetuses diagnosed with CHD. At the time of diagnosis, fetal biometry was performed and brain perfusion was assessed by middle cerebral artery pulsatility index (MCA-PI), cerebroplacental ratio (CPR) and fractional moving blood volume (FMBV). The results were compared with those of 95 normal fetuses matched for gestational age. RESULTS Median gestational age at diagnosis was 22 + 3 (range, 20 + 0 to 23 + 5) weeks. Fetuses with CHD showed significantly lower MCA-PI and CPR Z-scores (-0.23 vs 0.34 and -0.37 vs 0.30, respectively; both P < 0.001) and higher FMBV Z-scores (2.35 vs 0.15; P < 0.001). FMBV > 95(th) percentile was observed in 81.1% of cases as compared with 10.5% in controls (P < 0.001). Moreover, cases showed significantly smaller biparietal diameter (BPD) and head circumference (HC) Z-scores (-1.61 vs -0.43 and -0.89 vs 0.09, respectively; both P < 0.001), with a higher proportion of BPD and HC measurements below the 5(th) percentile compared with controls (51.6% vs 13.7% and 26.3% vs 4.2%, respectively; both P < 0.001). These findings were more pronounced in those cases with types of CHD associated with compromised oxygenated blood delivery to the brain, such as left outflow tract obstruction and transposition of the great arteries. CONCLUSIONS A high proportion of fetuses with CHD have a smaller head and increased brain perfusion already in the second trimester, suggesting an early onset of the mechanisms leading to poorer neurodevelopment later in life.

Abstract
OBJECTIVES To evaluate, in a cohort of 248 fetuses seen at a tertiary referral center, the frequency of isolated ventricular septal defects (VSD) among all congenital heart defects (CHD), the association with chromosomal and postnatal anomalies and the rate of spontaneous closure. METHODS This was a 6-year study on 10,800 women referred for fetal echocardiography, with 995 confirmed cases of CHD. The prevalence and characteristics of VSDs were analyzed, including follow-up until 1 year of age. Multivariate binary logistic regression analysis was performed to test the independent contribution of the ratio of the diameter of the VSD to that of the aorta (VSD/aorta ratio) (< 0.5 or ≥ 0.5) and location of VSD (perimembranous or muscular) in the prediction of spontaneous closure before the age of 1 year. RESULTS Two hundred and forty-eight VSDs (24.9% of all CHDs) were diagnosed, of which 216 (87.1%) were muscular and 32 (12.9%) perimembranous. Median gestational age at diagnosis was 30.4 (range, 17-41) weeks and mean size 2.6 ± 0.77 mm. Clinically relevant chromosomal anomalies were found in one (3.1%) perimembranous VSD compared with none in 216 muscular defects (P = 0.12). Postnatal malformations were diagnosed in eight of the 211 cases (3.8%) evaluated at 12 months postpartum. Spontaneous closure occurred prenatally in 13 fetuses (5.2%) and postnatally in 151 of the 198 infants (76.3%) who had an open VSD at birth. Closure was predicted by the VSD/aorta ratio (odds ratio (OR) 0.445 (95% CI, 0.216-0.914); P < 0.03) and location (OR 0.385 (95% CI, 0.160-0.926); P < 0.03). CONCLUSIONS In our fetal cardiology unit, isolated muscular VSD is today the most prevalent CHD. In contrast to the findings of postnatal studies, muscular VSDs were more common than perimembranous VSDs. Perimembranous VSDs were associated with a higher risk of chromosomal anomalies than were muscular VSDs, which had a similar risk to those of normal pregnancies. Spontaneous closure of the VSD was frequent and occurred in most cases postnatally.

Abstract
BACKGROUND There is limited evidence of the role of working conditions as prognostic factors for non-work-related sickness absence (i.e. absence due to injuries or diseases of non-occupational origin). AIMS To analyse the association between working conditions and time to return to work (RTW) in workers with long-term (>15 days) non-work-related sickness absence. METHODS We followed up a total of 655 workers, who completed a baseline questionnaire including physical and psychosocial work factors, until their non-work-related long-term sickness absence ended. Time to RTW was determined based on the health insurance company register. Cox proportional hazard models were constructed to evaluate the associations between working conditions and time to RTW. RESULTS A self-perceived high level of physical activity at work and work with back twisted or bent were related to longer duration of sickness absence. We did not find any strong evidence of associations between psychosocial work factors and time to RTW, although higher job insecurity and low reward showed marginal statistical significance. CONCLUSIONS Hazardous physical working conditions are associated with longer duration of non-work-related sickness absence. Workplace ergonomic interventions could conceivably shorten the length of sickness absence that has not originated at work.

Abstract
OBJECTIVE To describe a new ultrasonographic marker, the 'question-mark' sign, to assist in the diagnosis of tetralogy of Fallot (TOF) in the fetus, and to evaluate its prevalence in TOF as compared with other cardiac defects. METHODS A prospective evaluation over a 5-year period of a consecutive series of 3998 pregnant women undergoing fetal echocardiography from 12 to 40 weeks' gestation due to high risk for congenital heart disease (CHD). Standard echocardiographic planes with color Doppler assessment and evaluation of the whole aortic arch, from the left ventricular outflow tract to the descending aorta in the axial upper mediastinum views, were performed. The question-mark sign corresponded with an enlarged and dilated ascending aorta and aortic arch in the three-vessel view of the upper fetal mediastinum. The frequency of this sign was evaluated in cases with TOF and in other cases of cardiac defects, as well as in fetuses with normal cardiac scans in this series. RESULTS CHD was diagnosed in a total of 447 (11.2%) fetuses at a median gestational age of 24 (range, 12-40) weeks. Forty-two of the 447 (9.4%) had TOF, of which 29 cases (69.0%) had classical TOF (pulmonary stenosis), nine (21.4%) pulmonary atresia and four (9.5%) absent pulmonary valve syndrome. A question-mark sign was observed in 16/29 (55.2%) cases of classical TOF and in 8/9 (88.9%) cases of TOF with pulmonary atresia. The sign was never observed in any of the cases of TOF with a right-sided aortic arch. Likewise, the sign was observed in 1/405 (0.2%) cases with other cardiac anomalies (a fetus with a complex cardiac defect) and in none of the fetuses with normal hearts. CONCLUSIONS The finding of an enlarged aorta with a question-mark shape should raise a strong suspicion of tetralogy of Fallot, in particular the variant with pulmonary atresia. This sign may be useful in screening considering that prenatal diagnosis of TOF by routine ultrasonography remains a challenge.

Abstract
OBJECTIVE To evaluate the accuracy of four-dimensional (4D) spatiotemporal image correlation (STIC) echocardiography for the diagnosis of fetal congenital heart disease (CHD) in a selected high-risk population. METHODS Three hundred and sixty-three pregnant women referred for suspected CHD on screening ultrasound were evaluated by means of conventional echocardiography between 14 and 41 weeks' gestation and 4D-STIC volumes were obtained (including gray-scale and color Doppler information). Stored volumes were analyzed, at least 1 year after they had been acquired, by examiners blinded to the patients' identities and outcomes. The STIC diagnoses were compared to those made on conventional two-dimensional echocardiography and the accuracy of diagnosis was assessed with respect to postnatal examination, or autopsy in cases of termination of pregnancy or perinatal death. RESULTS The mean gestational age at volume acquisition was 24 + 5 weeks. STIC evaluation was possible in 98% of cases. Twenty-one cases were lost to follow-up, with a total of 167 normal hearts and 175 cases of CHD diagnosed at postnatal evaluation. The overall accuracy, sensitivity, specificity and positive and negative predictive values of STIC in determining the presence or absence of CHD were 91.6, 94.9, 88.1, 89.7 and 94.0%, respectively. Absolute concordance with the final specific diagnosis among cases with confirmed CHD was 74.3% for STIC echocardiography, compared with 81.7% for real-time evaluation. CONCLUSION 4D-STIC echocardiography performed by experienced operators can be used in fetuses at risk for cardiac anomalies in order to reliably provide reassurance of normality or to accurately diagnose major structural heart defects.

Abstract
Placenta previa (PP), with a frequency of 5-7% in the second trimester, is considered one of the most important causes of obstetric hemorrhage. Surgical curettage is the classically recommended method to perform a midtrimester termination of pregnancy (TOP) in the presence of PP. Recent clinical reports suggest that induction of delivery is possible in these cases, but no information on mifepristone-misoprostol regimen is available. We present 2 cases of mifepristone-misoprostol midtrimester TOP with a diagnosis of complete PP. In both cases, a preinduction feticide was performed. Neither of the 2 cases presented a significant maternal bleeding. This report is relevant considering that this regimen is the most widely used and generally reported as the safest and most effective medical midtrimester TOP method.

Abstract
OBJECTIVE To assess the intra- and interobserver repeatability of the evaluation of fetal cardiac structures and measurements using spatiotemporal image correlation (STIC) technology in each trimester of pregnancy. METHODS Four-dimensional (4D)-STIC volumes from 150 low-risk pregnancies were acquired at first-, second- or third-trimester scan for later analysis by two different reviewers. A total of 19 items, including the evaluation of 14 structures as well as five measurements of the fetal heart, were evaluated. The reliability of qualitative variables was evaluated using Cohen's kappa and absolute agreement analysis while that of quantitative parameters was assessed using the intraclass correlation coefficient (ICC). RESULTS Forty-five, 47 and 47 STIC volumes were included in the final analysis from the first, second and third trimesters, respectively. For the evaluation of cardiac structures, good or excellent intra- and interobserver agreement (kappa > 0.6) was obtained in 12/14 and 9/14, respectively, while absolute agreement was > 90% for most structures evaluated. Regarding the quantitative cardiac measurements, ICC values were above 0.90 for all but cardiac axis (intraobserver ICC, 0.81 and interobserver ICC, 0.61). There were no significant differences in the repeatability values observed for qualitative or quantitative parameters among the trimesters of pregnancy. CONCLUSION Cardiac examination from 4D-STIC volumes showed a high repeatability between and within observers in each trimester of pregnancy.

Abstract
OBJECTIVE To evaluate the independent contribution of ductus venosus (DV) blood flow assessment at 11-14 weeks' gestation to the prediction of congenital heart defects (CHD) in chromosomally normal fetuses, irrespective of the value of the nuchal translucency thickness (NT). METHODS During a 4-year period, all singleton pregnancies from 11 + 0 to 13 + 6 weeks' gestation were scanned for NT and DV blood flow in a tertiary center. Abnormal DV blood flow was defined as either absent or reversed flow during atrial contraction (AR-DV). Fetal echocardiography was performed in all cases with either NT > 99(th) percentile or AR-DV. Follow-up was assessed by postnatal examination or autopsy in cases of termination of pregnancy or perinatal death. RESULTS A total of 6120 pregnancies were scanned at a median gestational age of 12 weeks, and 45 cases of CHD were detected. AR-DV was found in 206 fetuses, of which 145 (70.4%) had a normal karyotype. Among fetuses with AR-DV and normal karyotype, 11 cases of CHD were diagnosed, giving a sensitivity of 24.4%, a positive predictive value of 7.6% and an odds ratio of 9.8. Increased NT (> 99(th) centile) was present in 55 of the 145 (37.9%) cases with AR-DV and normal karyotype, and in 6/11 (54.5%) of those with CHD. Thus, the group of 90 fetuses with abnormal DV blood flow and normal NT contained five cases of CHD, for a sensitivity of 11.1%, a positive predictive value of 5.5% and an odds ratio of 8.5. Right-heart anomalies were predominant in those cases with isolated AR-DV (4/5), but no specific CHD pattern was found in those with increased NT. The detection rate of CHD by the combined use of increased NT and/or AR-DV in the first trimester improved from 28.9% (13/45) to 40.0% (18/45). CONCLUSIONS In experienced hands, abnormal DV blood flow in the first trimester is an independent predictor of CHD and should constitute an indication for early echocardiography. In this study, the use of DV blood flow assessment increased early detection of CHD by 11% with respect to the use of NT measurement alone.

Abstract
OBJECTIVE To evaluate the prevalence of and perinatal outcome associated with increased nuchal translucency thickness (NT) > 99(th) percentile in dichorionic and monochorionic twins with normal karyotype. METHODS Two hundred and six consecutive twin pregnancies (166 dichorionic and 40 monochorionic) underwent an NT scan during a 4-year period. In those with NT > 99(th) percentile and normal karyotype, we performed first- and second-trimester anomaly scans, fetal echocardiography at 14-16 and 20-22 weeks, maternal serology and, in monochorionic pregnancies, serial ultrasound examinations every other week. Perinatal outcome was recorded. RESULTS There were 10 (4.95%) pregnancies in which one of the fetuses had NT > 99(th) percentile and normal karyotype, including five fetuses (1.5%) in dichorionic and five (6.25%) in monochorionic pregnancies. During the same period the prevalence of NT > 99(th) percentile and normal karyotype in singleton pregnancies studied in our center was 2.6%. Among the 10 twins affected, six (60%) were diagnosed with structural abnormalities (three dichorionic and three monochorionic), and two intrauterine fetal demises occurred (one dichorionic and one monochorionic). Thus, the perinatal outcome was normal in only two of the pregnancies, one dichorionic and one monochorionic. CONCLUSIONS The prevalence of NT > 99(th) percentile in dichorionic twins with a normal karyotype is similar to that in singletons. In monochorionic twins we confirmed previous studies reporting an increased prevalence compared with singletons. NT > 99(th) percentile with a normal karyotype in twins was associated with a high rate of fetal abnormalities and/or fetal demise (overall 80%) irrespective of chorionicity.

Abstract
Adequate initial configurations for molecular dynamics simulations consist of arrangements of molecules distributed in space in such a way to approximately represent the system's overall structure. In order that the simulations are not disrupted by large van der Waals repulsive interactions, atoms from different molecules must keep safe pairwise distances. Obtaining such a molecular arrangement can be considered a packing problem: Each type molecule must satisfy spatial constraints related to the geometry of the system, and the distance between atoms of different molecules must be greater than some specified tolerance. We have developed a code able to pack millions of atoms, grouped in arbitrarily complex molecules, inside a variety of three-dimensional regions. The regions may be intersections of spheres, ellipses, cylinders, planes, or boxes. The user must provide only the structure of one molecule of each type and the geometrical constraints that each type of molecule must satisfy. Building complex mixtures, interfaces, solvating biomolecules in water, other solvents, or mixtures of solvents, is straightforward. In addition, different atoms belonging to the same molecule may also be restricted to different spatial regions, in such a way that more ordered molecular arrangements can be built, as micelles, lipid double-layers, etc. The packing time for state-of-the-art molecular dynamics systems varies from a few seconds to a few minutes in a personal computer. The input files are simple and currently compatible with PDB, Tinker, Molden, or Moldy coordinate files. The package is distributed as free software and can be downloaded from http://www.ime.unicamp.br/~martinez/packmol/.

Abstract
OBJECTIVES To evaluate the potential value of early fetal echocardiography (EFE) by means of four-dimensional (4D) spatiotemporal image correlation (STIC) technology for either reassurance of normality or prenatal diagnosis of major congenital heart defects (CHDs). METHODS Sixty-nine pregnant women from 11 to 15 weeks' gestation underwent EFE. 4D-STIC volumes were acquired by the transvaginal approach for later review by two different examiners. STIC evaluation was considered complete when the four-chamber view, and the origin and double-crossing of the great arteries were identified correctly. Color Doppler imaging was used to detect either septal shunts or transvalvular regurgitation/aliasing suggesting abnormalities. STIC diagnoses were compared with those of conventional EFE. Reliability was assessed by postnatal examination, or autopsy in cases of termination of pregnancy or perinatal death. RESULTS The median gestational age at volume acquisition was 13 + 3 weeks. Eleven (15.9%) cases of CHD were diagnosed. A complete EFE was possible in 64 cases. We were able to provide reassurance of normality in 51 of the 53 confirmed normal hearts, with no false-positive results for major defects, although two minor defects (one ventricular septal defect (VSD) and one persistent left superior vena cava) were falsely suspected. The only false negative was a significant VSD at birth overlooked by both observers. Therefore, the total accuracy of STIC-EFE was 95.3% (61/64), with sensitivity, specificity, and positive and negative predictive values of 90.9%, 96.2%, 83.3% and 98.1%. The accuracy of conventional EFE (98.4%, 63/64) was slightly better than that of STIC, with no false-positive results recorded. CONCLUSIONS Offline evaluation of 4D-STIC acquired volumes of the fetal heart in the first and early second trimester of pregnancy is reliable not only for early reassurance of normal cardiac anatomy but also to diagnose most major structural heart defects.

Abstract
OBJECTIVE In Spain, sick pay benefits for work-related sick leave episodes are higher than for non-work-related episodes. Our aim is to assess whether time to return to work is longer for higher paid sick leave episodes than for lower paid episodes. METHODS We used data from 62,376 work-related and 76,932 non-work-related sick leave episodes occurring among 338,226 workers from 56,099 companies in Spain in 2002. All episodes were followed for up to 18 months. Episodes were classified by a physician as being work- or non-work-related according to medico-legal judgments. The median episode duration and the 25th and 75th percentiles were calculated. The probability of remaining absent from work was estimated by a non-parametric estimator of the marginal survival function. The time ratio between both types of sick leave was estimated by a log-logistic regression model, using non-work-related episodes as the reference. RESULTS Median episode duration (25th-75th percentiles) was 11 (6-21) days for work-related episodes and 9 (4-29) days for non-work-related episodes. Time to return to work was longer for work-related episodes than for non-work-related episodes of less than 16 days (time ratio: 1.19 in men and 1.08 in women), while the opposite was observed for episodes of more than 15 days (0.58 in men and 0.40 in women). CONCLUSIONS Sick pay benefits have a limited effect on time to return to work after a sick leave episode.

Abstract
OBJECTIVES To construct gestational age (GA)-based reference ranges for the uterine artery (UtA) mean pulsatility index (PI) at 11-41 weeks of pregnancy. METHODS A prospective cross-sectional observational study was carried out of 20 consecutive singleton pregnancies for each completed gestational week at 11-41 weeks. UtAs were examined by color and pulsed Doppler imaging, and the mean PI, as well as the presence or absence of a bilateral protodiastolic notch, were recorded. Polynomials were fitted by means of least-square regression to estimate the relationship between the mean UtA-PI and GA. RESULTS A total of 620 women were included. A second-degree polynomial (Log(e) mean UtA-PI = 1.39 - 0.012 x GA + GA(2) x 0.0000198, with GA measured in days), after a natural logarithmic transformation, was selected to model our data. There was a significant decrease in the mean UtA-PI between 11 weeks (mean PI, 1.79; 95(th) centile, 2.70) and 34 weeks (mean PI, 0.70; 95(th) centile, 0.99). It then became more stable up until 41 weeks (mean PI, 0.65; 95(th) centile, 0.89). CONCLUSIONS The mean UtA-PI shows a progressive decrease until the late stages of pregnancy. Reference ranges for mean UtA-PI may have clinical value in screening for placenta-associated diseases in the early stages of pregnancy, and in evaluating patients with pregnancy-induced hypertension and/or small-for-gestational age fetuses during the third trimester.

Abstract
OBJECTIVE To study the linkage between material deprivation and mortality from all causes, for men and women separately, in the capital cities of the provinces in Andalusia and Catalonia (Spain). METHODS A small-area ecological study was devised using the census section as the unit for analysis. 188,983 Deaths occurring in the capital cities of the Andalusian provinces and 109,478 deaths recorded in the Catalan capital cities were examined. Principal components factorial analysis was used to devise a material deprivation index comprising the percentage of manual labourers, unemployment and illiteracy. A hierarchical Bayesian model was used to study the relationship between mortality and area deprivation. MAIN RESULTS In most cities, results show an increased male mortality risk in the most deprived areas in relation to the least depressed. In Andalusia, the relative risks between the highest and lowest deprivation decile ranged from 1.24 (Malaga) to 1.40 (Granada), with 95% credibility intervals showing a significant excess risk. In Catalonia, relative risks ranged between 1.08 (Girona) and 1.50 (Tarragona). No evidence was found for an excess of female mortality in most deprived areas in either of the autonomous communities. CONCLUSIONS Within cities, gender-related differences were revealed when deprivation was correlated geographically with mortality rates. These differences were found from an ecological perspective. Further research is needed in order to validate these results from an individual approach. The idea to be analysed is to identify those factors that explain these differences at an individual level.

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
OBJECTIVE To analyse trends in mortality inequalities by educational level for main causes of death among men and women in Barcelona, Spain, at the turn of the 21st century (1992-2003). METHODS The population of reference was all Barcelona residents older than 19 years. All deaths between 1992-2003 were included. Educational level was obtained through record linkage between the mortality register and the municipal census of Barcelona city. Variables studied were age, sex, educational level, period of death (four periods of 3 years) and cause of death. Age-standardised mortality rates for each educational level, sex and period were calculated. Poisson regression models were fitted to obtain relative index of inequality (RII) for educational level, adjusted for age for the time-periods. RESULTS RII for all causes of death was constant (around 1.5), but rate differences were higher in 1995-7 (715.6 per 100,000 in men and 352.8 in women) than in other periods and tended to decrease in men over the periods. Analysis of inequality trends by specific causes of death shows a stable trend for the majority of causes, with higher mortality among those with less education for all causes of death except lung cancer and breast cancer among women having RII below 1. CONCLUSIONS Relative inequalities in total mortality by sex in Barcelona did not change during the 12 years studied, whereas absolute inequalities tended to decrease in men. Our study fills an important gap in southern Europe and Spanish literature on trends during this period.

OBJECTIVES To evaluate mesothelioma death trends in Spain and to predict the number of future cases of mesothelioma. METHODS After descriptive analysis of mesothelioma mortality data, an age-period-cohort model was applied to estimate future mesothelioma deaths. RESULTS From 1977 to 2001, 1928 men over 35 years of age died of mesothelioma in Spain. Projections indicate that 1321 men are expected to die from mesothelioma between 2007 and 2016. CONCLUSION It is expected that mesothelioma deaths will increase at least until 2016. Available data do not allow prediction of the year when mortality will start to decrease.

Abstract
OBJECTIVES To evaluate the characteristics and association with perinatal outcome of the aortic isthmus (AoI) circulation as assessed by Doppler imaging in preterm growth-restricted fetuses with placental insufficiency. METHODS This was a prospective cross-sectional study. Fifty-one fetuses with intrauterine growth restriction (IUGR) and either an umbilical artery (UA) pulsatility index (PI) > 95(th) centile or a cerebroplacental ratio < 5(th) centile were examined at 24-36 weeks' gestation. AoI impedance indices (PI and resistance index) and absolute velocities (peak systolic (PSV), end-diastolic and time-averaged maximum (TAMXV) velocities), were measured in all cases and compared with reference ranges by gestational age. Furthermore, fetuses were stratified into two groups according to the direction of the diastolic blood flow in the AoI: those with antegrade flow (n = 41) and those with retrograde flow (n = 10). Clinical surveillance was based on gestational age and Doppler assessment of the UA, middle cerebral artery and ductus venosus (DV). Adverse perinatal outcome was defined as stillbirth, neonatal death and severe morbidity (respiratory distress syndrome, bronchopulmonary dysplasia, Grade III/IV intraventricular hemorrhage, necrotizing enterocolitis and a neonatal intensive care unit stay > 14 days). RESULTS Adverse perinatal outcome was significantly associated with an increased AoI-PI (area under the curve 0.77; 95% CI, 0.63-0.92; P < 0.005). A significant correlation (P < 0.001) was found between retrograde blood flow in the AoI and adverse perinatal outcome, the overall perinatal mortality being higher in the retrograde group (70% vs. 4.8%, P < 0.001). In 4/5 (80%) fetuses the reversal of flow in the AoI preceded that in the DV by 24-48 h. AoI-PSV and AoI-TAMXV were < 5(th) centile in 40/51 (78%) and 48/51 (94%) cases, respectively, whereas AoI-PI was > 95(th) centile in 21/51 (41%) cases. CONCLUSIONS Retrograde flow in the AoI in growth-restricted fetuses correlates strongly with adverse perinatal outcome. Absolute velocities in the AoI are decreased in growth-restricted fetuses. The data suggest a potential role for Doppler imaging of the AoI in the clinical surveillance of fetuses with severe IUGR, which should be confirmed in larger prospective studies.

Abstract
Acquired neuromyotonia is defined as continuous muscle activity originated in peripheral nerve due to alterations of the motor axon membrane. It has been considered a paraneoplastic syndrome in patients with neoplasms of the immune system, mainly lymphomas. Similarly, involvement of the motor neuron has been described as an uncommon paraneoplastic complication, also in relationship to lymphomas. We report a rare case, given the presence of two uncommon paraneoplastic manifestations such as neuromyotonia and reversible paraneoplastic lower motor neuronopathy secondary to clear cell renal carcinoma.

Abstract
OBJECTIVE To describe sequential changes in uterine artery waveform between the first and second trimesters of gestation and to analyze their association with the subsequent risk of hypertensive disorders and fetal growth restriction (IUGR). METHODS Sequential uterine artery Doppler recordings were obtained in a final cohort of 870 singleton pregnancies over two gestational age intervals: 11-14 weeks and 19-22 weeks. The left and right uterine arteries were examined by color and pulsed Doppler and the mean pulsatility index (PI) as well as the presence of a bilateral protodiastolic notch were recorded during both intervals. Pregnancies were followed for occurrence of hypertensive disorders and IUGR. RESULTS Mean uterine artery PI showed a significant linear decrease within each of the two intervals considered, while the prevalence of a bilateral notch showed decreasing values only throughout 11-14 weeks of gestation. Sixty-four (7.3%) pregnancies developed a hypertensive disorder and/or IUGR, including three (0.34%) cases of gestational hypertension, 24 cases of pre-eclampsia (2.75%) and 37 (4.25%) of IUGR. Compared with pregnancies with a normal outcome, complicated pregnancies showed a significantly higher prevalence of a bilateral notch and a higher mean PI in each of the two intervals studied. Compared with normal pregnancies, complicated pregnancies had a significantly higher persistence of a bilateral notch (30% vs. 8%), a higher proportion of women with an abnormal first-trimester uterine artery PI shifting to normal in the second trimester (14% vs. 4%) and a higher incidence of a normal first-trimester mean PI that shifted to abnormal in the second trimester (13% vs. 4%). Persistence of an abnormal mean PI from the first to the second trimester identified the group with the greatest risk for adverse perinatal outcome (OR, 10.7; 95% CI, 3.7-30.9). In addition, women in whom the uterine artery mean PI shifted from abnormal to normal between the two trimesters and women in whom the reverse shift occurred showed a similar intermediate risk (OR, 5; 95% CI, 2.1-10.6), comparable to that in women with persistence of a bilateral notch (OR, 5.6; 95% CI, 2.9-10.7). CONCLUSIONS The sequence of changes in uterine flow between the first and second trimesters correlates with the subsequent development of hypertensive disorders and IUGR. Women with a persistent abnormal mean PI represent the group with the greatest risk for adverse perinatal outcome.

Abstract
OBJECTIVES To analyze fetal echocardiographic findings of absent pulmonary valve syndrome (APVS), its association with chromosomal and extracardiac anomalies including nuchal translucency (NT) and the outcome after diagnosis. METHODS Data of 14 fetuses with confirmed APVS retrospectively collected in two tertiary referral centers between 1998 and 2004 were analyzed. The variables examined were: reason for referral, gestational age at diagnosis and associated abnormalities, including first trimester NT thickness. Cardiac evaluation included measurement of cardiothoracic ratio, diameter of pulmonary arteries and Doppler flow in the pulmonary trunk. Information was retrieved from clinical files, recorded videotapes and stored images. Karyotyping including examination for the 22q11 deletion was performed in all cases. RESULTS Mean gestational age at diagnosis was 28 weeks, with 5/14 (36%) diagnosed before 22 weeks. In 13/14 (93%) there was an associated ventricular septal defect (subaortic in 12 fetuses and inlet-type in one) and all 13 had tetralogy of Fallot. Enlargement of the central pulmonary arteries and cardiomegaly were present in all cases diagnosed after 22 weeks. Of the five fetuses in which APVS was detected before 22 weeks, four (80%) had a normal pulmonary trunk diameter, two (40%) had normal pulmonary branches and three (60%) had normal cardiac size. The arterial duct was absent in 11/14 (79%). A correlation between presence of the arterial duct and the size of the central pulmonary arteries or cardiomegaly could not be established. Increased NT was observed in 4/10 cases (40%) for which this information was available. 22q11 microdeletion was diagnosed in three fetuses (21%). There were five terminations of pregnancy, one intrauterine death, five neonatal deaths and one infant death. Of the six neonates with respiratory distress, only one (17%) survived and of the eight babies in whom there was an intention to treat, two survived (25%). CONCLUSIONS APVS can be accurately diagnosed by fetal echocardiography but screening ultrasound in the mid-second trimester is likely to have a low detection rate, probably due to the incomplete expression of the disease at this point. Many fetuses with APVS have an increased NT in the first trimester and this may help an earlier recognition of the defect. The most common associated karyotype anomaly is 22q11 microdeletion. Enlargement of the central pulmonary arteries is mainly related to the gestational age at diagnosis. Our results confirm that the outlook for these patients is extremely poor.

Abstract
OBJECTIVE To establish reference ranges for blood flow velocity waveforms (FVW) of the fetal aortic isthmus (AoI) during the second and third trimesters of pregnancy. METHODS This was a prospective cross-sectional observational study involving 458 uncomplicated singleton pregnancies between 19 and 37 weeks of gestation. Fetal AoI Doppler parameters were assessed in either the longitudinal aortic arch view or the three vessels and trachea view. Regression analysis was used to determine gestational-age-specific reference ranges and to construct nomograms for the following Doppler parameters: pulsatility index (PI), resistance index (RI) and peak systolic (PSV), end-diastolic (EDV) and time-averaged maximum (TAMXV) velocities. Intra- and interobserver reproducibility were evaluated by calculating intraclass correlation coefficients (ICCs) and limits of agreement. RESULTS Reliable FVW in the AoI were obtained in all cases. Acceptable intra- and interobserver reproducibility was obtained. With advancing gestation, there was a significant increase in PSV, TAMXV and PI, whereas RI and EDV remained constant during the second half of pregnancy. No cases of absent or reversed flow during diastole were detected. CONCLUSION Normal data of the fetal AoI blood FVW throughout the second and third trimesters of pregnancy are provided. The reported Doppler profiles may be of clinical use in the assessment of hemodynamically compromised growth-restricted fetuses.
