Abstract
STUDY QUESTION Is resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity associated with differential changes in endocrine and metabolic parameters (weight, insulin resistance, anti-Müllerian hormone (AMH), and androgens) compared to women with PCOS who remained anovulatory? SUMMARY ANSWER Resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity is associated with changes in serum 11β-hydroxyandrostenedione (11OHA4) concentrations. WHAT IS KNOWN ALREADY Lifestyle interventions have been shown to reduce clinical and biochemical hyperandrogenism in women with PCOS. Weight loss of 5-10% may reverse anovulatory status, thereby increasing natural conception rates. However, the mechanisms underlying why some women with PCOS remain anovulatory and others resume ovulation after weight loss are unclear. Reproductive characteristics at baseline and a greater degree of change in endocrine and metabolic features with lifestyle intervention may be crucial for ovulatory response. STUDY DESIGN, SIZE, DURATION We used data and samples originating from an earlier randomized controlled trial (RCT), which examined the efficacy of a 6-month lifestyle intervention prior to infertility treatment compared to prompt infertility treatment on live birth rate in women with obesity. A total of 577 women with obesity (BMI > 29 kg/m2) were randomized between 2009 and 2012. Anovulatory women with PCOS who were allocated to the intervention arm of the original RCT (n = 95) were included in the current analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS We defined women as having resumed ovulation (RO+) based on the following criteria: spontaneous pregnancy; or assignment to expectant management; or IUI in natural cycles as the treatment strategy after lifestyle intervention. Steroid hormones were measured using liquid chromatography tandem mass spectrometry. Generalized estimating equations with adjustment for baseline measures and interaction between group and time was used to examine differences in changes of endocrine and metabolic parameters between RO+ (n = 34) and persistently anovulatory women (RO-, n = 61) at 3 and 6 months after intervention. MAIN RESULTS AND THE ROLE OF CHANCE At baseline, the mean ± SD age was 27.5 ± 3.6 years in the RO+ group and 27.9 ± 4.1 years in the RO- group (P = 0.65), and the mean ± SD weights were 101.2 ± 9.5 kg and 105.0 ± 14.6 kg, respectively (P = 0.13). Baseline AMH concentrations showed significant differences between RO+ and RO- women (median and interquartile range [IQR] 4.7 [3.2; 8.3] versus 7.2 [5.3; 10.8] ng/ml, respectively). Baseline androgen concentrations did not differ between the two groups. During and after lifestyle intervention, both groups showed weight loss; changes in 11OHA4 were significantly different between the RO+ and RO groups (P-value for interaction = 0.03). There was a similar trend for SHBG (interaction P-value = 0.07), and DHEA-S (interaction P-value = 0.06), with the most pronounced differences observed in the first 3 months. Other parameters, such as AMH and FAI, decreased over time but with no difference between the groups. LIMITATIONS, REASONS FOR CAUTION No high-resolution transvaginal ultrasonography was used to confirm ovulatory status at the end of the lifestyle program. The small sample size may limit the robustness of the results. WIDER IMPLICATIONS OF THE FINDINGS Reduction of androgen concentrations during and after lifestyle intervention is associated with recovery of ovulatory cycles. If our results are confirmed in other studies, androgen concentrations could be monitored during lifestyle intervention to provide individualized recommendations on the timing of resumption of ovulation in anovulatory women with PCOS and obesity. STUDY FUNDING/COMPETING INTEREST(S) The study was supported by a grant from ZonMw, the Dutch Organization for Health Research and Development (50-50110-96-518). The Department of Obstetrics and Gynecology of the UMCG received an unrestricted educational grant from Ferring Pharmaceuticals BV, The Netherlands.

Abstract
OBJECTIVE To investigate the association between epidural analgesia (EDA) vs patient-controlled remifentanil analgesia (PCRA) and emergency delivery for presumed fetal compromise, in relation to birth-weight quintile. METHODS This was a post-hoc per-protocol analysis of the RAVEL multicenter equivalence randomized controlled trial. Non-anomalous singleton pregnancies between 36 + 0 and 42 + 6 weeks' gestation were randomized at the time of requesting pain relief to receive EDA or PCRA. The primary outcome was emergency delivery for presumed fetal compromise. Secondary outcomes included mode of delivery and neonatal outcomes. Analysis was performed according to birth-weight quintile and was corrected for relevant confounding variables. RESULTS Of 619 pregnant women, 336 received PCRA and 283 received EDA. Among women receiving EDA, 14.8% had an emergency delivery for presumed fetal compromise, compared with 8.3% of women who received PCRA. After adjusting for parity, women receiving EDA had higher odds of presumed fetal compromise compared to those receiving PCRA (odds ratio, 1.69 (95% CI, 1.01-2.83)). A statistically significant linear-by-linear association was observed between presumed fetal compromise and birth-weight quintile (P = 0.003). The incidence of emergency delivery for presumed fetal compromise was highest in women receiving EDA and delivering a neonate with a birth weight in the lowest quintile. CONCLUSIONS Intrapartum EDA is associated with a higher rate of emergency delivery for presumed fetal compromise compared to treatment with PCRA. Birth-weight quintile is a strong predictor of this outcome, independent of pain management method. © 2023 The Authors.

Abstract
OBJECTIVES To determine the rate of emergency delivery for presumed fetal compromise after epidural analgesia (EDA) compared with that after alternative analgesia or no analgesia, and to assess whether this rate is increased in pregnancies with reduced placental reserve. METHODS This was a nationwide registry-based cohort study of 629 951 singleton pregnancies delivered at 36 + 0 to 42 + 0 weeks of gestation that were recorded in the Dutch national birth registry between 2014 and 2018, including 120 426 cases that received EDA, 86 957 that received alternative analgesia and 422 568 that received no analgesia during labor. Pregnancies with congenital anomaly, chromosomal abnormality, fetal demise, planned Cesarean delivery, non-cephalic presentation at delivery and use of multiple forms of analgesia were excluded. The primary outcome was emergency delivery for presumed fetal compromise. Secondary outcomes included delivery characteristics and neonatal outcome. Negative binomial regression analysis was stratified by parity and results are presented according to birth-weight centile, after adjusting for confounding. RESULTS Among women who received EDA, 13.2% underwent emergency delivery for presumed fetal compromise, compared with 4.1% of women who had no analgesia (relative risk (RR), 3.23 (95% CI, 3.16-3.31)) and 7.0% of women who received alternative analgesia (RR, 1.72 (95% CI, 1.67-1.77)). Independent of birth weight, the RR of presumed fetal compromise after EDA vs no analgesia was higher in parous women (adjusted RR (aRR), 2.15 (95% CI, 2.04-2.27)) compared with nulliparous women (RR, 1.88 (95% CI, 1.84-1.94)). Stratified for parity, the effect of EDA was modified significantly by birth-weight centile (interaction P-value, < 0.001 for nulliparous and 0.004 for parous women). The emergency delivery rate following EDA was highest in those with a birth weight < 5th centile (25.2% of nulliparous and 16.6% of parous women), falling with each increasing birth-weight centile category up to the 91st -95th centile (11.8% of nulliparous and 7.2% of parous women). CONCLUSIONS Intrapartum EDA is associated with a higher risk of emergency delivery for presumed fetal compromise compared with no analgesia and alternative analgesia, after adjusting for relevant confounding. The highest rate of emergency delivery for presumed fetal compromise was observed at the lowest birth-weight centiles. RRs of emergency delivery for presumed fetal compromise after EDA were modestly but consistently modified by birth-weight centile, supporting the hypothesis that the adverse effects of EDA are exacerbated by reduced placental function. While EDA provides effective pain relief during labor, alternative strategies for pain management may be preferable in pregnancies with a high background risk of fetal compromise. © 2023 The Authors.

Abstract
STUDY QUESTION Is a thin endometrial lining before ovulation triggering more prevalent in patients utilizing preimplantation genetic testing for monogenic disease (PGT-M) compared to the regular IVF/ICSI population and is this associated with prior hormonal contraceptive use? SUMMARY ANSWER Thin (<8 mm) endometrial lining is more prevalent in PGT-M patients compared to the regular IVF/ICSI population and is associated with both longer prior hormonal contraceptive use and a shorter cessation interval of hormonal contraceptives before IVF/ICSI treatment. WHAT IS KNOWN ALREADY Thin endometrial lining has been associated with lower pregnancy rates in IVF/ICSI cycles and increased chances of miscarriage and low birth weight. Endometrial thinning and atrophy occur during hormonal contraceptive use. Patients utilizing PGT-M typically use hormonal contraceptives up until treatment to avoid the risk of conception of a genetically affected child. Whether this could negatively affect endometrial thickness achieved during subsequent IVF/ICSI cycles is not known. STUDY DESIGN, SIZE, DURATION A retrospective case control study was performed, including all PGT-M patients attending the University Medical Centre Groningen (cases), between 2009 and 2018. The control group consisted of two non-PGT IVF/ICSI patients for each PGT-M patient, matched for age and treatment period. PARTICIPANTS/MATERIALS, SETTING, METHODS First cycles of 122 PGT-M patients and 240 controls were included. Cessation interval of hormonal contraceptives was categorized as late cessation (cessation <1 year prior to treatment) or early cessation (>1 year prior to treatment). Endometrial thickness was routinely measured on the day of hCG triggering or 1 day prior. The prevalence of an endometrial lining <8 mm was compared between PGT-M patients and controls. Hormonal contraceptive use (both duration and cessation interval) was compared between both groups. Univariable and multivariable regression analyses were performed to identify risk factors for thin endometrial lining. In addition, cycle and pregnancy outcomes were compared within control/PGT-M groups between patients with endometrial lining > or <8 mm. MAIN RESULTS AND THE ROLE OF CHANCE Thin endometrial lining on the day of hCG triggering was found significantly more often in the PGT-M group, compared to controls: 32% vs 11% (mean difference 21.0%, 95% CI: 11.7, 30.3%). As expected, more patients in the PGT-M group ceased their hormonal contraception late (<1 year): 64% vs 2% in the control group (mean difference 61.9%, 95% CI: 53.0, 70.8%). Average duration of hormonal contraceptive use was 10.6 years in the PGT-M group vs 9.3 years in controls (mean difference 1.3 years, 95% CI: 0.2, 2.3 years). Multivariable logistic regression analysis identified late cessation (OR: 6.0, 95% CI: 1.9-19.2) and duration of prior hormonal contraceptive use (OR per year increase 1.1, 95% CI: 1.0-1.2) as significant independent risk factors for a thin endometrial lining. In relation to outcome, we found a statistically significant increase in miscarriage rate in PGT-M patients with an endometrial lining <8 mm compared to those with an endometrial lining >8 mm (20.0% vs 1.7%, mean difference 18.3%, 95% CI: 2.3, 34.3%). A trend towards lower birth weight and gestation- and gender-adjusted birth weight (z-score) was also found in this group. No statistically significant differences were detected in pregnancy rate, live birth rate, or incidence of preterm delivery or SGA. Within the control group, no statistically significant differences were found in outcomes between patients with an endometrial lining <8 compared to an endometrial lining >8 mm. LIMITATIONS, REASONS FOR CAUTION The study is retrospective. Various types of hormonal contraceptives were reported which possibly exert different effects on the endometrial lining. In relation to pregnancy outcome measures, numbers were very limited; therefore, no firm conclusions should be drawn. WIDER IMPLICATIONS OF THE FINDINGS This study provides further insight into the role of prior hormonal contraceptive use as a possible contributor to the occurrence of thin endometrial lining during ART treatment. Future studies should provide more information on its clinical relevance, to determine whether PGT-M patients can be reassured, or should be counselled to stop hormonal contraceptive use and change to an alternative contraceptive method prior to PGT treatment. STUDY FUNDING/COMPETING INTERESTS No specific funding was used and no conflicts of interests are declared. TRIAL REGISTRATION NUMBER N/A.

Abstract
Abstract
Study question
Which steroid hormone (ratio) has the highest discriminatory value in the biochemical diagnosis of polycystic ovary syndrome (PCOS) in women with infertility and obesity?
Summary answer
Androstenedione (A4) is a potentially useful discriminatory biomarker for PCOS in women with obesity, whereas Testosterone (T)/Dihydrotestosterone (DHT) and 11-oxygenated androgens are not.
What is known already
The best biomarker to assess biochemical hyperandrogenism in PCOS is still under discussion. Serum total or free T, followed by Free Androgen Index (FAI), and Dehydroepiandrosterone Sulfate (DHEA-S) are the most widely used biomarkers. T/DHT ratio has been proposed as a useful biomarker for PCOS. Moreover, a recent study demonstrated 11-oxygenated androgens represent the majority of circulating androgens in PCOS. Whether this is also relevant in women with obesity is unclear. We aimed to assess the discriminatory value of different steroid hormones and their ratios for PCOS as well as adverse metabolic phenotype within PCOS in women with obesity.
Study design, size, duration
We used the baseline data and samples originating from an RCT that examined whether a six-month lifestyle intervention prior infertility treatment in women with obesity improved live birth rate, compared to prompt infertility treatment. In total of 577 women with obesity were randomized between 2009 and 2012. Women were diagnosed with PCOS according to the Rotterdam criteria. Metabolic syndrome was diagnosed based on the revised criteria of the National Cholesterol Education Program.
Participants/materials, setting, methods
Women with PCOS comprised the study group (N = 132). Ovulatory women with idiopathic, tubal or male factor infertility were the control group (N = 83). Women were excluded when blood sampling was performed in the luteal phase or when baseline samples were unavailable. The steroid hormones were measured using LC-MS/MS. 11β-hydroxyandrostenedione (11OHA4) and 11-ketotestosterone (11KT) were analyzed using LC-MS/MS in a separate method. The discriminatory value was based on receiver operator characteristic (ROC) curves with adjustment for age.
Main results and the role of chance
The mean age was 28.1 years in the PCOS group and 30.9 years in the control group (p < 0.001). BMI was not significantly different (36.0±3.2 versus 35.7±3.5, p = 0.51). Among the tested steroid hormones (ratios), SHBG, A4, T, DHT, 11KT, FAI, T/DHT ratio, and T/A4 ratio showed statistically significant differences between the PCOS and the control group. DHEA, DHEA-S, 11OHA4 did not differ between the groups. The crude AUCs of FAI, T, A4, T/DHT ratio, SHBG, 11KT, T/A4 ratio, and DHT in ROC analysis for representing PCOS were 0.85, 0.84, 0.81, 0.70, 0.62, 0.59, 0.58, and 0.57 respectively. Among the markers with crude AUCs≥0.70, the incremental value of the marker A4 (AUC difference: 0.14, 95%CI: 0.07 to 0.21), T (0.18, 95%CI: 0.10 to 0.25), and FAI (0.18, 95%CI: 0.10 to 0.25) in addition to age showed significant improvement, but T/DHT ratio (0.02, 95%CI: –0.01 to 0.04) did not. However, the combination of A4 together with T or FAI did improve discriminatory value of individual T or FAI (AUC difference: –0.001, 95%CI: –0.004 to 0.003 and 0.007, –0.007 to 0.02, respectively). None of the measured steroid hormones (ratios) have promising discriminatory value for adverse metabolic phenotype within PCOS in women with obesity.
Limitations, reasons for caution
This is a post-hoc analysis and no power calculation was performed. There was a significant difference in age between women with and without PCOS, and residual confounding might exist. All PCOS patients in this analysis were infertile and obese, and it is conceivable that milder PCOS phenotypes are not represented.
Wider implications of the findings
T/DHT ratio and 11-oxygenated androgens might not serve as a promising discriminatory biomarker for PCOS in women with obesity, nor for adverse metabolic phenotype within PCOS in these women. A4 is a potential biomarker for PCOS diagnosis in women with infertility and obesity, however, its utility potency needs further validation.

Abstract
STUDY QUESTION Do mental health and sexual function differ between women with or without polycystic ovary syndrome (PCOS) with comparable BMI and fertility characteristics? SUMMARY ANSWER Women with PCOS have a poorer mental quality of life than women without PCOS, but there were no differences in symptoms of depression, anxiety, physical quality of life or sexual function. WHAT IS KNOWN ALREADY Various studies suggest that women with PCOS have poorer mental health, such as higher symptoms of anxiety and depression with a lower quality of life, and have an impaired sexual function compared to women without PCOS. However, in most studies, BMI and infertility status differ between women with and without PCOS, which may hamper comparability. STUDY DESIGN SIZE DURATION This study is a cross-sectional analysis of a 5-year follow-up of a randomized controlled trial (RCT) among women with obesity and a history of infertility. PARTICIPANTS/MATERIALS SETTING METHODS Participants in this follow-up study of an RCT were women with obesity and infertility randomized to a lifestyle intervention followed by infertility treatment or prompt infertility treatment (control), stratified by ovulatory status and trial centre. In total, 173 (30.0%) women of the 577 women randomized in the initial trial participated in this follow-up study, with a mean follow-up of 5.5 years (range 3.7-7.0 years); of these women 73 had been diagnosed with PCOS and 100 did not have PCOS. Participants completed questionnaires on symptoms of anxiety and depression (Hospital Anxiety and Depression scale (HADS)), quality of life (36-item Short Form Health Survey (SF-36)) and sexual function (McCoy Female Sexuality Questionnaire (MFSQ)). We also compared quality of life subscale scores in women with and without PCOS and compared them to an age-matched Dutch reference population with average BMI. Effect sizes were calculated to assess the differences. MAIN RESULTS AND THE ROLE OF CHANCE Symptoms of anxiety and depression, physical quality of life and sexual function did not differ significantly between obese women with and without PCOS. However, women with PCOS had a worse mental quality of life summary component score (-3.60 [95% CI -6.72 to -0.56]), mainly due to a lower score on the subscale 'role limitations due to emotional problems' (-12.41 [95% CI -22.78 to -2.28]), compared to women without PCOS. However, compared to an age-matched Dutch reference population, the obese infertile women with and without PCOS both scored lower on almost all physical and mental quality of life subscales. LIMITATIONS REASONS FOR CAUTION These are secondary analyses of the follow-up study of the RCT. No power analysis was performed for the outcomes included in this analysis and, as our study had a relatively small sample size, the null findings could be based on insufficient power to detect small differences between the groups. Our study population had a high mean BMI (average total group 34.5 [SD ± 5.1]); therefore, our results may only be generalizable to women with obesity. WIDER IMPLICATIONS OF THE FINDINGS Our results indicate that PCOS status is associated with impaired mental quality of life. Anxiety and depression, physical quality of life and sexual function in obese infertile women with PCOS seem more related to the obesity than the PCOS status.

Abstract
OBJECTIVE To construct reference values for fetal urinary bladder distension in pregnancy and use Z-scores as a diagnostic tool to differentiate posterior urethral valves (PUV) from urethral atresia (UA). METHODS This was a prospective cross-sectional study in healthy singleton pregnancies aimed at constructing nomograms of fetal urinary bladder diameter and volume between 15 and 35 weeks' gestation. Z-scores of longitudinal bladder diameter (LBD) were calculated and validated in a cohort of fetuses with megacystis with ascertained postnatal or postmortem diagnosis, collected from a retrospective, multicenter study. Correlations between anatomopathological findings, based on medical examination of the infant or postmortem examination, and fetal megacystis were established. The accuracy of the Z-scores was evaluated by receiver-operating-characteristics (ROC)-curve analysis. RESULTS Nomograms of fetal urinary bladder diameter and volume were produced from three-dimensional ultrasound volumes in 225 pregnant women between 15 and 35 weeks of gestation. A total of 1238 urinary bladder measurements were obtained. Z-scores, derived from the fetal nomograms, were calculated in 106 cases with suspected lower urinary tract obstruction (LUTO), including 76 (72%) cases with PUV, 22 (21%) cases with UA, four (4%) cases with urethral stenosis and four (4%) cases with megacystis-microcolon-intestinal hypoperistalsis syndrome. Fetuses with PUV showed a significantly lower LBD Z-score compared to those with UA (3.95 vs 8.83, P < 0.01). On ROC-curve analysis, we identified 5.2 as the optimal Z-score cut-off to differentiate fetuses with PUV from the rest of the study population (area under the curve, 0.84 (95% CI, 0.748-0.936); P < 0.01; sensitivity, 74%; specificity, 86%). CONCLUSIONS Z-scores of LBD can distinguish reliably fetuses with LUTO caused by PUV from those with other subtypes of LUTO, with an optimal cut-off of 5.2. This information should be useful for prenatal counseling and management of LUTO. © 2021 The Authors.

Abstract
Abstract
Study question
Does lifestyle intervention prior to in vitro fertilization (IVF) improve embryo utilization rate (EUR) and cumulative live birth rate (CLBR) in women with obesity?
Summary answer
A six-month lifestyle intervention preceding IVF improved neither EUR, nor CLBR in women with obesity.
What is known already
A randomized controlled trial (RCT) evaluating the efficacy of a low caloric liquid formula diet (LCD) preceding IVF in women with obesity was unable to demonstrate an effect of LCD on embryo quality and live birth rate. In that study, only one fresh embryo transfer (ET) or, in case of freeze-all strategy, the first transfer with frozen-thawed embryos was reported. We hypothesized that any effect on embryo quality of a lifestyle intervention in women with obesity undergoing IVF treatment is better revealed by EUR and CLBR after transfer of fresh and frozen-thawed embryos.
Study design, size, duration
This is a nested cohort study within an RCT. The LIFEstyle study examined whether a six-month lifestyle intervention prior to assisted reproductive technology (ART) in women with obesity improved live birth rate, compared to prompt ART within 24 months after randomization. In the original study, 577 women with obesity and infertility were assigned to a lifestyle intervention followed by ART (N = 290) or to prompt ART (N = 287) between 2009 and 2012.
Participants/materials, setting, methods
The first IVF cycle with successful oocyte retrieval was included, resulting in 51 participants in the intervention group and 72 in the control group. EUR was defined as the proportion of inseminated/injected oocytes that could be transferred or cryopreserved as an embryo. Analysis was performed per cycle and per oocyte/embryo. CLBR was defined as the percentage of participants with at least one live birth from the first fresh and subsequent frozen-thawed ET(s).
Main results and the role of chance
The overall mean age was 31.64 years, and the mean BMI was 35.40 ± 3.21 kg/m2 in the intervention group, and 34.86 ± 2.86 kg/m2 in the control group (P = 0.33). The mean difference of weight change at six months between the two groups was in favor of the intervention group (mean difference in kg: –3.14, 95% CI: –5.73 – –0.56). The median (Q25; Q75) of EUR was 33.3% (12.5; 60.0) in the intervention group and 33.3% (16.7; 50.0) in the control group in the per cycle analysis (adjusted B: 2.7%, 95% CI: –8.6 – 14.0). In the per oocyte/embryo analysis, in total 280 oocytes were injected or inseminated in the intervention group, 113 were utilized (transferred or cryopreserved embryos, EUR = 40.4%); in the control group EUR was 30.8% (142/461). The lifestyle intervention did not significantly improve EUR (adjusted OR: 1.36, 95% CI: 0.94 – 1.98) in the per oocyte/embryo analysis taking into account the interdependency of the oocytes per participant. CLBR was not significantly different between the intervention group and the control group after adjusting for type of infertility (male factor and unexplained) and smoking (27.5% vs 22.2%, adjusted OR: 1.03, 95% CI: 0.43 – 2.47).
Limitations, reasons for caution
This study is a nested cohort study within an RCT, and no power calculation was performed. The randomization was not stratified for indicated treatment. The limited absolute weight loss and the short duration of the lifestyle intervention might be insufficient to affect EUR and CLBR.
Wider implications of the findings: Our data do not support the hypothesis of a beneficial effect of lifestyle intervention on embryo quality and CLBR after IVF in women with obesity.

Abstract
Background Elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels at 20 weeks’ gestation predict adverse cardiovascular (CV) complications during pregnancy in women with congenital heart disease (CHD). To improve early risk assessment in these women, we investigated the predictive value of first-trimester NT-proBNP for CV complications and its association with ventricular function during pregnancy. Methods Pregnant women with CHD, previously enrolled in a prospective national study or evaluated by an identical protocol, were included. Clinical data, echocardiographic evaluation and NT-proBNP measurements were obtained at 12, 20 and 32 weeks’ gestation. Elevated NT-proBNP was defined as > 235 pg/ml (95th percentile reference value of healthy pregnant women in the literature). Results We examined 126 females (mean age 29 years). Elevated NT-proBNP at 12 weeks was associated with CV complications (n = 7, 5.6%, odds ratio 10.9, p = 0.004). Arrhythmias were the most common complication (71%). The negative predictive value of low NT-proBNP to exclude CV complications was 97.2%. In women with CV complications, NT-proBNP levels remained high throughout pregnancy, while a decrease was seen in women without CV complications (p < 0.001 for interaction between group and time). At 12 weeks, higher NT-proBNP levels were associated with impaired subpulmonary ventricular function (p < 0.001) and also with a decline in subpulmonary ventricular function later in pregnancy (p = 0.012). Conclusions In this study, first-trimester NT-proBNP levels were associated with adverse CV complications and a decline in subpulmonary ventricular function later in pregnancy in women with CHD. Early NT-proBNP evaluation is useful for tailored care in pregnant women with CHD.

Abstract
PURPOSE Assessing quality of life (QoL) after esophageal replacement (ER) for long gap esophageal atresia (LGEA). METHODS All patients after ER for LGEA with gastric pull-up (GPU n = 9) or jejunum interposition (JI n = 14) at the University Medical Center Groningen and Utrecht (1985-2007) were included. QoL was assessed with 1) gastrointestinal-related QoL using the Gastrointestinal Quality of Life Index (GIQLI)), 2) general QoL (Child Health questionnaire CHF87-BREF (children)/World Health Organization questionnaire WHOQOL-BREF (adults)), and 3) health-related QoL (HRQoL) (TNO AZL TACQoL/TAAQoL). Association of morbidity (heartburn, dysphagia, dyspnea on exertion, recurrent cough) and (HR)QoL was evaluated. RESULTS Six patients after GPU (75%) and eight patients after JI (57%) responded to the questionnaires (mean age 15.7, SD 5.9, 12 male, two female). Mean gastrointestinal, general and health-related QoL total scores of the patients were comparable to healthy controls. However, young adults reported a worse physical functioning (p = 0.02) but better social functioning compared to peers (p = 0.01). Morbidity was not associated with significant differences in (HR)QoL. CONCLUSIONS With the current validated QoL most patients after ER with GPU and JI for LGEA have normal generic and disease specific QoL scores. Postoperative morbidity does not seem to influence (HR)QoL. TYPE OF STUDY Prognosis Study. LEVEL OF EVIDENCE III.

Abstract
STUDY QUESTION Over a time period of 3 years, which order of expectant management (EM), IUI with ovarian stimulation (IUI-OS) and IVF is the most cost-effective for couples with unexplained subfertility with the female age below 38 years? SUMMARY ANSWER If a live birth is considered worth €32 000 or less, 2 years of EM followed by IVF was the most cost-effective, whereas above €32 000 this was 1 year of EM, 1 year of IUI-OS and then 1 year of IVF. WHAT IS KNOWN ALREADY IUI-OS and IVF are commonly used fertility treatments for unexplained subfertility although many couples can conceive naturally, as no identifiable barrier to conception could be found by definition. Few countries have guidelines on when to proceed with medically assisted reproduction (MAR), mostly based on the expected probability of live birth after treatment, but there is a lack of evidence to support the strategies proposed by these guidelines. The increased uptake of IUI-OS and IVF over the past decades and costs related to reimbursement of these treatments are pressing concerns to health service providers. For MAR to remain affordable, sustainable and a responsible use of public funds, guidance is needed on the cost-effectiveness of treatment strategies for unexplained subfertility, including EM. STUDY DESIGN, SIZE, DURATION We developed a decision analytic Markov model that follows couples with unexplained subfertility of which the woman is under 38 years of age for a time period of 3 years from completion of the fertility workup onwards. We divided the time axis of 3 years into three separate periods, each comprising 1 year. The model was based on contemporary evidence, most notably the dynamic prediction model for natural conception, which was combined with MAR treatment effects from a network meta-analysis on randomized controlled trials. We changed the order of options for managing unexplained subfertility for the 1 year periods to yield five different treatment policies in total: IVF-EM-EM (immediate IVF), EM-IVF-EM (delayed IVF), EM-EM-IVF (postponed IVF), IUIOS-IVF-EM (immediate IUI-OS) and EM-IUIOS-IVF (delayed IUI-OS). PARTICIPANTS/MATERIALS, SETTING, METHODS The main outcomes per policy over the 3-year period were the probability of live birth, the average treatment and delivery costs, the probability of multiple pregnancy, the incremental cost-effectiveness ratio (ICER) and finally, which policy yields the highest net benefit in which costs for a policy were deducted from the health effects, i.e. live births gained. We chose the Dutch societal perspective, but the model can be easily modified for other locations or other perspectives. The probability of live birth after EM was taken from the dynamic prediction model for natural conception and updated for Years 2 and 3. The relative effects of IUI-OS and IVF in terms of odds ratios, taken from the network meta-analysis, were applied to the probability of live birth after EM. We applied standard discounting procedures for economic analyses for Years 2 and 3. The uncertainty around effectiveness, costs and other parameters was assessed by probabilistic sensitivity analysis in which we drew values from distributions and repeated this procedure 20 000 times. In addition, we changed model assumptions to assess their influence on our results. MAIN RESULTS AND THE ROLE OF CHANCE From IVF-EM-EM to EM-IUIOS-IVF, the probability of live birth varied from approximately 54-64% and the average costs from approximately €4000 to €9000. The policies IVF-EM-EM and EM-IVF-EM were dominated by EM-EM-IVF as the latter yielded a higher cumulative probability of live birth at a lower cost. The policy IUIOS-IVF-EM was dominated by EM-IUIOS-IVF as the latter yielded a higher cumulative probability of live birth at a lower cost. After removal of policies that were dominated, the ICER for EM-IUIOS-IVF was approximately €31 000 compared to EM-EM-IVF. The range of ICER values between the lowest 25% and highest 75% of simulation replications was broad. The net benefit curve showed that when we assume a live birth to be worth approximately €20 000 or less, the policy EM-EM-IVF had the highest probability to achieve the highest net benefit. Between €20 000 and €50 000 monetary value per live birth, it was uncertain whether EM-EM-IVF was better than EM-IUIOS-IVF, with the turning point of €32 000. When we assume a monetary value per live birth over €50 000, the policy with the highest probability to achieve the highest net benefit was EM-IUIOS-IVF. Results for subgroups with different baseline prognoses showed the same policies dominated and the same two policies that were the most likely to achieve the highest net benefit but at different threshold values for the assumed monetary value per live birth. LIMITATIONS, REASONS FOR CAUTION Our model focused on population level and was thus based on average costs for the average number of cycles conducted. We also based the model on a number of key assumptions. We changed model assumptions to assess the influence of these assumptions on our results. The change in relative effectiveness of IVF over time was found to be highly influential on results and their interpretation. WIDER IMPLICATIONS OF THE FINDINGS EM-EM-IVF and EM-IUIOS-IVF followed by IVF were the most cost-effective policies. The choice depends on the monetary value assigned to a live birth. The results of our study can be used in discussions between clinicians, couples and policy makers to decide on a sustainable treatment protocol based on the probability of live birth, the costs and the limitations of MAR treatment.

Abstract
OBJECTIVE The Hypertension and Preeclampsia Intervention Trial At near Term-I (HYPITAT-I) randomized controlled trial showed that, in women with gestational hypertension or mild pre-eclampsia at term, induction of labor, compared with expectant management, was associated with improved maternal outcome without compromising neonatal outcome. The aim of the current study was to evaluate the impact of these findings on obstetric management and maternal and perinatal outcomes in The Netherlands. METHODS We retrieved data for the period 2000-2014 from the Dutch National Perinatal Registry, including 143 749 women with gestational hypertension or pre-eclampsia and a singleton fetus in cephalic presentation, delivered between 36 + 0 and 40 + 6 weeks of gestation (hypertensive disorder of pregnancy (HDP) group). Pregnant women without HDP were used as the reference group (n = 1 649 510). The HYPITAT-I trial was conducted between 2005 and 2008. To study the impact of HYPITAT-I, we compared rate of induction of labor, mode of delivery and maternal and perinatal outcomes in the periods before (2000-2005) and after (2008-2014) the trial. We also differentiated between hospitals that participated in HYPITAT-I and those that did not. RESULTS In the HDP group, the rate of induction of labor increased from 51.1% before the HYPITAT-I trial to 64.2% after it (relative risk (RR), 1.26; 95% CI, 1.24-1.27). Maternal mortality decreased from 0.022% before the trial to 0.004% after it (RR, 0.20; 95% CI, 0.06-0.70) and perinatal death decreased from 0.49% to 0.27% (RR, 0.54; 95% CI, 0.45-0.65), which was attributable mostly to a decrease in fetal death. Both the increase in induction rate and the reduction in hypertensive complications were more pronounced in hospitals that participated in the HYPITAT-I trial than in those that did not. Following HYPITAT-I, the rate of induction of labor also increased (by 4.6 percentage points) in the reference group; however, the relative increase in the HDP group (13.1 percentage points) was significantly greater (P < 0.001 for the interaction). The reduction in maternal and perinatal deaths did not differ significantly between the HDP and reference groups. There was a decreased incidence of placental abruption in both HDP and reference groups, which was significantly greater in the HDP than in the reference group (P < 0.001 for the interaction). There was also an increased incidence of emergency Cesarean section in both HDP and reference groups; however, this change was significantly greater in the reference than in the HDP group (P < 0.001 for the interaction). CONCLUSION Following the HYPITAT-I trial, there was a higher rate of induction of labor and improved obstetric outcome in term pregnancies complicated by HDP in The Netherlands.

Abstract
OBJECTIVE Pregnant women with congenital heart disease (CHD) have an increased risk of abnormal uteroplacental flow, measured from the second trimester onwards, which is associated with pregnancy complications affecting the mother and the fetus. Maternal right ventricular (RV) dysfunction has been suggested as a predisposing factor for impaired uteroplacental flow in these women. The aim of this study was to investigate the association of first-trimester uteroplacental flow measurements with prepregnancy maternal cardiac function and pregnancy complications in women with CHD, with particular focus on the potential role of RV (dys)function. METHODS This study included 138 pregnant women with CHD from the prospective ZAHARA III study (Zwangerschap bij Aangeboren HARtAfwijkingen; Pregnancy and CHD). Prepregnancy clinical and echocardiographic data were collected. Clinical evaluation, echocardiography (focused on RV function, as assessed by tricuspid annular plane systolic excursion (TAPSE)) and uterine artery (UtA) pulsatility index (PI) measurements were performed at 12, 20 and 32 weeks of gestation. Univariable and multivariable regression analyses were performed to assess the association between prepregnancy variables and UtA-PI during pregnancy. The association between UtA-PI at 12 weeks and cardiovascular, obstetric and neonatal complications was also assessed. RESULTS On multivariable regression analysis, prepregnancy TAPSE was associated negatively with UtA-PI at 12 weeks of gestation (β = -0.026; P = 0.036). Women with lower prepregnancy TAPSE (≤ 20 mm vs > 20 mm) had higher UtA-PI at 12 weeks (1.5 ± 0.5 vs 1.2 ± 0.6; P = 0.047). Increased UtA-PI at 12 weeks was associated with obstetric complications (P = 0.003), particularly hypertensive disorders (pregnancy-induced hypertension and pre-eclampsia, P = 0.019 and P = 0.026, respectively). CONCLUSIONS In women with CHD, RV dysfunction before pregnancy seems to impact placentation, resulting in increased resistance in UtA flow, which is detectable as early as in the first trimester. This, in turn, is associated with pregnancy complications. Early monitoring of uteroplacental flow might be of value in women with CHD with pre-existing subclinical RV dysfunction to identify pregnancies that would benefit from close obstetric surveillance.

Abstract
OBJECTIVE Hypertensive disorders affect 3-10% of pregnancies. Delayed delivery carries maternal risks, while early delivery increases fetal risk, so appropriate timing is important. The aim of this study was to compare immediate delivery with expectant management for prevention of adverse maternal and neonatal outcomes in women with hypertensive disease in pregnancy. METHODS CENTRAL, PubMed, MEDLINE and ClinicalTrials.gov were searched for randomized controlled trials comparing immediate delivery to expectant management in women presenting with gestational hypertension or pre-eclampsia without severe features from 34 weeks of gestation. The primary neonatal outcome was respiratory distress syndrome (RDS) and the primary maternal outcome was a composite of HELLP syndrome and eclampsia. The PRISMA-IPD guideline was followed and a two-stage meta-analysis approach was used. Relative risks (RR) and numbers needed to treat or harm (NNT/NNH) with 95% CI were calculated to evaluate the effect of the intervention. RESULTS Main outcomes were available for 1724 eligible women. Compared with expectant management, immediate delivery reduced the composite risk of HELLP syndrome and eclampsia in all women (0.8% vs 2.8%; RR, 0.33 (95% CI, 0.15-0.73); I2 = 0%; NNT, 51 (95% CI, 31.1-139.3)) as well as in the pre-eclampsia subgroup (1.1% vs 3.5%; RR, 0.39 (95% CI, 0.15-0.98); I2 = 0%). Immediate delivery increased RDS risk (3.4% vs 1.6%; RR, 1.94 (95% CI 1.05-3.6); I2 = 24%; NNH, 58 (95% CI, 31.1-363.1)), but depended upon gestational age. Immediate delivery in the 35th week of gestation increased RDS risk (5.1% vs 0.6%; RR, 5.5 (95% CI, 1.0-29.6); I2 = 0%), but immediate delivery in the 36th week did not (1.5% vs 0.4%; RR, 3.4 (95% CI, 0.4-30.3); I2 not applicable). CONCLUSION In women with hypertension in pregnancy, immediate delivery reduces the risk of maternal complications, whilst the effect on the neonate depends on gestational age. Specifically, women with a-priori higher risk of progression to HELLP, such as those already presenting with pre-eclampsia instead of gestational hypertension, were shown to benefit from earlier delivery. © 2019 The Authors.

Abstract
Background The preconceptional period may be an optimal window of opportunity to improve lifestyle. We previously showed that a 6 month preconception lifestyle intervention among women with obesity and infertility was successful in decreasing the intake of high caloric snacks and beverages, increasing physical activity and in reducing weight in the short term. We now report the effects of the preconception lifestyle intervention on diet, physical activity and body mass index (BMI) at 5.5 years (range = 3.7–7.0 years) after the intervention. Methods We followed women who participated in the LIFEstyle study, a multicentre RCT in which women with obesity and infertility were assigned to a six-month lifestyle intervention program or prompt infertility treatment (N = 577). Diet and physical activity 5.5 years later were assessed with an 173-item food frequency questionnaire (N = 175) and Actigraph triaxial accelerometers (N = 155), respectively. BMI was calculated from self-reported weight and previously measured height (N = 179). Dietary intake, physical activity, and BMI in the intervention and control group were compared using multivariate regression models. Additionally, dietary intake, physical activity and BMI of women allocated to the intervention arm with successful weight loss during the intervention (i.e. BMI < 29 kg/m2 or ≥ 5% weight loss), unsuccessful weight loss and the control group were compared with ANCOVA. Results Although BMI did not differ between the intervention and control group 5.5 years after the intervention (− 0.5 kg/m2 [− 2.0;1.1]; P = 0.56), the intervention group did report a lower energy intake (− 216 kcal/day [− 417;-16]; P = 0.04). Women in the intervention arm who successfully lost weight during the intervention had a significantly lower BMI at follow-up compared to women in the intervention arm who did not lose weight successfully (− 3.4 kg/m2 [− 6.3;-0.6]; P = 0.01), and they reported a significantly lower energy intake compared to the control group (− 301 kcal [− 589;-14]; P = 0.04). Macronutrient intake, diet quality, and physical activity did not differ between the intervention and control group, irrespective of successful weight loss during the intervention. Conclusions In our study population, a preconception lifestyle intervention led to reduced energy intake 5.5 years later. Additionally, women allocated to the intervention group who were successful in losing weight during the intervention also had a lower BMI at follow-up. This shows the potential sustainable effect of a preconception lifestyle intervention.

Abstract
Obesity is a rising problem, especially among women of reproductive age. Overweight and obesity reduce both physical and mental health. Lifestyle interventions could have beneficial effects on both, but an overview of the effects on mental health, especially in women of reproductive age, is currently lacking. Therefore, the aim of this review was to assess the effect of lifestyle interventions on symptoms of depression and anxiety in women of reproductive age with overweight or obesity. The databases MEDLINE, EMBASE and PsycINFO were searched from inception to June 2018 for published randomized controlled trials (RCTs). We included lifestyle intervention RCTs in women of reproductive age with overweight or obesity that assessed effects on symptoms of depression and/or anxiety. The difference between baseline and post-intervention scores on symptoms of depression and anxiety for the intervention and control group was analysed. Meta-analysis was performed with a random effects model. The search resulted in 5,316 citations, and after screening five RCTs were included, in which 571 women were randomized. The effect of lifestyle interventions on depression scores was investigated among 224 women from five RCTs. The pooled estimate for the mean difference was -1.35 (95% CI, -2.36 to -0.35, p = 0.008). The effect of lifestyle interventions on anxiety levels was studied among 148 women from four RCTs, resulting in a pooled estimate of -1.74 (-2.62 to -0.87, p < 0.001). Based on five RCTs, meta-analyses showed that lifestyle interventions in women of reproductive age with overweight or obesity consistently reduce symptoms of depression and anxiety.

Abstract
STUDY QUESTION What is the prevalence of chromosomal abnormalities in azoospermic men and what are the clinical consequences in terms of increased risk for absent spermatogenesis, miscarriages and offspring with congenital malformations? SUMMARY ANSWER The prevalence of chromosomal abnormalities in azoospermia was 14.4%, and the number of azoospermic men needed to be screened (NNS) to identify one man with a chromosomal abnormality with increased risk for absence of spermatogenesis was 72, to prevent one miscarriage 370-739 and to prevent one child with congenital malformations 4751-23 757. WHAT IS KNOWN ALREADY Infertility guidelines worldwide advise screening of non-iatrogenic azoospermic men for chromosomal abnormalities, but only few data are available on the clinical consequences of this screening strategy. STUDY DESIGN, SIZE, DURATION This retrospective multicentre cross-sectional study of non-iatrogenic azoospermic men was performed at the University Hospital Brussels, Belgium, and the University Medical Centre Groningen, The Netherlands, between January 2000 and July 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS Analysis of clinical registries retrospectively identified 1663 non-iatrogenic azoospermic men with available results of karyotyping and FSH serum levels. Iatrogenic azoospermia was an exclusion criterion, defined as azoospermia after spermatotoxic medical treatment, exogenous androgen suppletion or vasectomy and/or vasovasostomy. Also, men with a clinical diagnosis of anejaculation or hypogonadotropic hypo-androgenism and/or FSH values <1.0 U/l were excluded. Chromosomal abnormalities were categorized according to their (theoretical) impact on clinical consequences for the patient (i.e. an increased risk for absence of spermatogenesis) and adverse pregnancy outcomes (i.e. miscarriage or offspring with congenital malformations), in both normogonadotropic (FSH < 10 U/l) and hypergonadotropic (FSH ≥ 10 U/l) azoospermia. We estimated the NNS for chromosomal abnormalities to identify one man with absence of spermatogenesis and to prevent one miscarriage or one child with congenital malformations, and calculated the surgical sperm retrieval rates per chromosomal abnormality. MAIN RESULTS AND THE ROLE OF CHANCE The overall prevalence of chromosomal abnormalities in azoospermia was 14.4% (95% CI 12.7-16.1%), its prevalence being higher in hypergonadotropic azoospermia (20.2%, 95% CI 17.8-22.7%) compared to normogonadotropic azoospermia (4.9%, 95% CI 3.2-6.6%, P < 0.001). Klinefelter syndrome accounted for 83% (95% CI 77-87%) of abnormalities in hypergonadotropic azoospermia. The NNS to identify one man with increased risk for absence of spermatogenesis was 72, to prevent one miscarriage 370-739, and to prevent one child with congenital malformations 4751-23 757. There was no clinically significant difference in NNS between men with normogonadotropic and hypergonadotropic azoospermia. The surgical sperm retrieval rate was significantly higher in azoospermic men with a normal karyotype (60%, 95% CI 57.7-63.1%) compared to men with a chromosomal abnormality (32%, 95% CI 25.9-39.0%, P < 0.001). The sperm retrieval rate in Klinefelter syndrome was 28% (95% CI 20.7-35.0%). LIMITATIONS, REASONS FOR CAUTION The absolute number of chromosomal abnormalities associated with clinical consequences and adverse pregnancy outcomes in our study was limited, thereby increasing the role of chance. Further, as there are currently no large series on outcomes of pregnancies in men with chromosomal abnormalities, our conclusions are partly based on assumptions derived from the literature. WIDER IMPLICATIONS OF THE FINDINGS The NNS found can be used in future cost-effectiveness studies and the evaluation of current guidelines on karyotyping in non-iatrogenic azoospermia. STUDY FUNDING/COMPETING INTEREST(S) None to declare.

Abstract
STUDY QUESTION What is the cost-effectiveness of lifestyle intervention preceding infertility treatment in obese infertile women? SUMMARY ANSWER Lifestyle intervention preceding infertility treatment as compared to prompt infertility treatment in obese infertile women is not a cost-effective strategy in terms of healthy live birth rate within 24 months after randomization, but is more likely to be cost-effective using a longer follow-up period and live birth rate as endpoint. WHAT IS KNOWN ALREADY In infertile couples, obesity decreases conception chances. We previously showed that lifestyle intervention prior to infertility treatment in obese infertile women did not increase the healthy singleton vaginal live birth rate at term, but increased natural conceptions, especially in anovulatory women. Cost-effectiveness analyses could provide relevant additional information to guide decisions regarding offering a lifestyle intervention to obese infertile women. STUDY DESIGN, SIZE, DURATION The cost-effectiveness of lifestyle intervention preceding infertility treatment compared to prompt infertility treatment was evaluated based on data of a previous RCT, the LIFEstyle study. The primary outcome for effectiveness was the vaginal birth of a healthy singleton at term within 24 months after randomization (the healthy live birth rate). The economic evaluation was performed from a hospital perspective and included direct medical costs of the lifestyle intervention, infertility treatments, medication and pregnancy in the intervention and control group. In addition, we performed exploratory cost-effectiveness analyses of scenarios with additional effectiveness outcomes (overall live birth within 24 months and overall live birth conceived within 24 months) and of subgroups, i.e. of ovulatory and anovulatory women, women <36 years and ≥36 years of age and of completers of the lifestyle intervention. Bootstrap analyses were performed to assess the uncertainty surrounding cost-effectiveness. PARTICIPANTS/MATERIALS, SETTINGS, METHODS Infertile women with a BMI of ≥29 kg/m2 (no upper limit) were allocated to a 6-month lifestyle intervention programme preceding infertility treatment (intervention group, n = 290) or to prompt infertility treatment (control group, n = 287). After excluding women who withdrew informed consent or who were lost to follow-up we included 280 women in the intervention group and 284 women in the control group in the analysis. MAIN RESULTS AND THE ROLE OF CHANCE Total mean costs per woman in the intervention group within 24 months after randomization were €4324 (SD €4276) versus €5603 (SD €4632) in the control group (cost difference of -€1278, P < 0.05). Healthy live birth rates were 27 and 35% in the intervention group and the control group, respectively (effect difference of -8.1%, P < 0.05), resulting in an incremental cost-effectiveness ratio of €15 845 per additional percentage increase of the healthy live birth rate. Mean costs per healthy live birth event were €15 932 in the intervention group and €15 912 in the control group. Exploratory scenario analyses showed that after changing the effectiveness outcome to all live births conceived within 24 months, irrespective of delivery within or after 24 months, cost-effectiveness of the lifestyle intervention improved. Using this effectiveness outcome, the probability that lifestyle intervention preceding infertility treatment was cost-effective in anovulatory women was 40%, in completers of the lifestyle intervention 39%, and in women ≥36 years 29%. LIMITATIONS, REASONS FOR CAUTION In contrast to the study protocol, we were not able to perform the analysis from a societal perspective. Besides the primary outcome of the LIFEstyle study, we performed exploratory analyses using outcomes observed at longer follow-up times and we evaluated subgroups of women; the trial was not powered on these additional outcomes or subgroup analyses. WIDER IMPLICATIONS OF THE FINDINGS Cost-effectiveness of a lifestyle intervention is more likely for longer follow-up times, and with live births conceived within 24 months as the effectiveness outcome. This effect was most profound in anovulatory women, in completers of the lifestyle intervention and in women ≥36 years old. This result indicates that the follow-up period of lifestyle interventions in obese infertile women is important. The scenario analyses performed in this study suggest that offering and reimbursing lifestyle intervention programmes in certain patient categories may be cost-effective and it provides directions for future research in this field. STUDY FUNDING/COMPETING INTEREST(S) The study was supported by a grant from ZonMw, the Dutch Organization for Health Research and Development (50-50110-96-518). The department of obstetrics and gynaecology of the UMCG received an unrestricted educational grant from Ferring pharmaceuticals BV, The Netherlands. B.W.J.M. is a consultant for ObsEva, Geneva.

Abstract
OBJECTIVE Pregnancy in women with surgically corrected tetralogy of Fallot (ToF) is associated with cardiac, obstetric and neonatal complications. We compared uteroplacental Doppler flow (UDF) measurements and pregnancy outcome in women with ToF and in healthy women and aimed to assess whether a relationship exists between cardiac function and UDF in women with ToF. METHODS We evaluated prospectively pregnant women with ToF and healthy pregnant women from the ZAHARA studies. Clinical evaluation, standardized echocardiography and UDF measurements were performed at 20 and 32 weeks' gestation. RESULTS We included 62 women with ToF and 69 healthy controls. Cardiac complications, mostly arrhythmia, occurred in 8.1% of women with ToF. There was a higher incidence of small-for-gestational age (21.0% vs 4.4%, P = 0.004) and low birth weight (16.1% vs 2.9%, P = 0.009) in the group of women with ToF than in healthy controls. In women with ToF, early diastolic notching of uterine artery waveform at 20 and 32 weeks occurred more frequently (9.8% vs 1.5%, P = 0.034 and 7.0% vs 0%, P = 0.025, respectively) and the umbilical artery pulsatility index at 32 weeks was higher (1.02 ± 0.20 vs 0.94 ± 0.17, P = 0.015) than in healthy controls. Right ventricular function parameters prepregnancy and at 20 weeks' gestation were significantly associated with abnormal UDF. UDF parameters were associated with adverse neonatal outcome. CONCLUSION The majority of women with surgically corrected ToF tolerate pregnancy well. However, UDF indices are more frequently abnormal in these women, suggesting impaired placentation. The association of impaired right ventricular function parameters with abnormal UDF suggests that cardiac dysfunction contributes to defective placentation or placental perfusion mismatch and may explain the increased incidence of obstetric and neonatal complications.

Abstract
STUDY QUESTION Do age, ovulatory status, severity of obesity and body fat distribution affect the effectiveness of lifestyle intervention in obese infertile women? SUMMARY ANSWER We did not identify a subgroup in which lifestyle intervention increased the healthy live birth rate however it did increase the natural conception rate in anovulatory obese infertile women. WHAT IS KNOWN ALREADY Obese women are at increased risk of infertility and are less likely to conceive after infertility treatment. We previously demonstrated that a 6-month lifestyle intervention preceding infertility treatment did not increase the rate of healthy live births (vaginal live birth of a healthy singleton at term) within 24 months of follow-up as compared to prompt infertility treatment in obese infertile women. Natural conceptions occurred more frequently in women who received a 6-month lifestyle intervention preceding infertility treatment. STUDY DESIGN, SIZE, DURATION This is a secondary analysis of a multicentre RCT (randomized controlled trial), the LIFEstyle study. Between 2009 and 2012, 577 obese infertile women were randomly assigned to a 6-month lifestyle intervention followed by infertility treatment (intervention group) or to prompt infertility treatment (control group). Subgroups were predefined in the study protocol, based on frequently used cut-off values in the literature: age (≥36 or <36 years), ovulatory status (anovulatory or ovulatory), BMI (≥35 or <35 kg/m2) and waist-hip (WH) ratio (≥0.8 or <0.8). PARTICIPANTS/MATERIALS, SETTING, METHODS Data of 564 (98%) randomized women who completed follow-up were analyzed. We studied the effect of the intervention program in various subgroups on healthy live birth rate within 24 months, as well as the rate of overall live births (live births independent of gestational age, mode of delivery and health) and natural conceptions within 24 months. Live birth rates included pregnancies resulting from both treatment dependent and natural conceptions. Logistic regression models with randomization group, subgroup and the interaction between randomization group and subgroup were used. Significant interaction was defined as a P-value <0.1. MAIN RESULTS AND THE ROLE OF CHANCE Neither maternal age, ovulatory status nor BMI had an impact on the healthy live birth rate within 24 months, nor did they influence the overall live birth rate within 24 months after randomization. WH ratio showed a significant interaction with the effect of lifestyle intervention on healthy live birth rate (P = 0.05), resulting in a lower healthy live birth rate in women with a WH ratio <0.8. WH ratio had no interaction regarding overall live birth rate (P = 0.27) or natural conception rate (P = 0.38). In anovulatory women, the effect of lifestyle intervention resulted in more natural conceptions compared to ovulatory women (P-value for interaction = 0.02). There was no interaction between other subgroups and the effect of the intervention on the rate of natural conception. LIMITATIONS, REASONS FOR CAUTION Since this was a subgroup analysis of a RCT and sample size determination of the trial was based on the primary outcome of the study, the study was not powered for analyses of all subgroups. WIDER IMPLICATIONS OF THE FINDINGS Our finding that lifestyle intervention leads to increased natural conception in anovulatory obese women could be used in the counselling of these women, but requires further research using an appropriately powered study in order to confirm this result. STUDY FUNDING/COMPETING INTERESTS The study was supported by a grant from ZonMw, the Dutch Organisation for Health Research and Development (50-50110-96-518).

Abstract
OBJECTIVE To evaluate caesarean section and adverse neonatal outcome rates after induction of labour or expectant management in women with an unripe cervix at or near term. DESIGN Secondary analysis of data from two randomised clinical trials. SETTING Data were collected in two nationwide Dutch trials. POPULATION Women with hypertensive disease (HYPITAT trial) or suspected fetal growth restriction (DIGITAT trial) and a Bishop score ≤6. METHODS Comparison of outcomes after induction of labour and expectant management. MAIN OUTCOME MEASURES Rates of caesarean section and adverse neonatal outcome, defined as 5-minute Apgar score ≤6 and/or arterial umbilical cord pH <7.05 and/or neonatal intensive care unit admission and/or seizures and/or perinatal death. RESULTS Of 1172 included women with an unripe cervix, 572 had induction of labour and 600 had expectant management. We found no significant difference in the overall caesarean rate (difference -1.1%, 95% CI -5.4 to 3.2). Induction of labour did not increase caesarean rates in women with Bishop scores from 3 to 6 (difference -2.7%, 95% CI -7.6 to 2.2) or adverse neonatal outcome rates (difference -1.5%, 95% CI -4.3 to 1.3). However, there was a significant difference in the rates of arterial umbilical cord pH <7.05 favouring induction (difference -3.2%, 95% CI -5.6 to -0.9). The number needed to treat to prevent one case of umbilical arterial pH <7.05 was 32. CONCLUSIONS We found no evidence that induction of labour increases the caesarean rate or compromises neonatal outcome as compared with expectant management. Concerns over increased risk of failed induction in women with a Bishop score from 3 to 6 seem unwarranted. TWEETABLE ABSTRACT Induction of labour at low Bishop scores does not increase caesarean section rate or poor neonatal outcome.

Abstract
STUDY QUESTION Is there an association between trisomic pregnancy, a marker for decreased oocyte quality, and the reduced oocyte quantity that follows ovarian surgery? SUMMARY ANSWER Previous ovarian surgery is not associated with an increased risk for a subsequent trisomic pregnancy. WHAT IS KNOWN ALREADY Ovarian surgery diminishes the number of oocytes. The risk for a trisomic pregnancy is suggested to be higher in women with fewer oocytes, independent of their chronological age. STUDY DESIGN, SIZE, DURATION This is a matched case-control study. Cases are women with a confirmed trisomic pregnancy occurring between 1 January 2000 and 31 December 2010 regardless of pregnancy outcome and controls are women that had a live born child without a trisomy. In total, there were 8573 participants in the study; 1723 cases and 6850 controls. PARTICIPANTS/MATERIALS, SETTING, METHODS Data were obtained from Danish medical registries. Matching criteria were maternal age and year of conception. Number of controls matched per case ranged from one to four. Among cases and controls with a trisomic pregnancy, 2.7% (46/1723) versus 2.5% (172/6850) had undergone ovarian surgery before pregnancy. MAIN RESULTS AND ROLE OF CHANCE History of ovarian surgery is not associated with a higher risk for a subsequent trisomic pregnancy (odds ratio = 1.00, 95% confidence interval 0.99-1.01). Subgroup analyses by indication of surgery and interval between ovarian surgery and pregnancy do not show an effect on trisomic pregnancy risk. LIMITATIONS, REASONS FOR CAUTION The medical registries used to select cases and controls did not contain information on surgical technique nor volume of ovarian tissue resected, previous trisomic pregnancy prior to the ovarian surgery or long-term use of oral contraceptives. Therefore, correction for these factors was not performed. WIDER IMPLICATIONS OF THE FINDINGS We did not confirm the hypothesis that ovarian surgery, a marker for decreased oocyte quantity, is related to trisomic pregnancy, a marker for decreased oocyte quality. This suggests that ovarian surgery, which has a direct reductive effect on the size of the follicle pool, may affect oocyte quality differently when compared with the reduction in follicle pool size due to ageing. STUDY FUNDING/COMPETING INTERESTS The study was supported by grants from the Gratama Stichting, University of Groningen and the University Medical Center Groningen, The Netherlands. Ø.L. has within the last 3 years received honoraria for speeches in pharmacoepidemiological issues, not related to this study. The Department of Obstetrics and Gynaecology receives unrestricted educational grants from Ferring Pharmaceuticals. A.H. received a grant from ZonMW (i.e. National Dutch Scientific funding) for a RCT not related to this publication. Dr A.H. received speakers fee from MSD for an educational presentation.

Abstract
BACKGROUND There is little knowledge about neonatal complications in GH and PE and induction at term, we aim to assess whether they can be predicted from clinical data. METHODS We used data of the HYPITAT trial and evaluated whether adverse neonatal outcome (Apgar score < 7, pH < 7.05, NICU admission) could be predicted from clinical data. Logistic regression, ROC analysis and calibration were used to identify predictors and evaluate the predictive capacity in an antepartum and intrapartum model. RESULTS We included 1153 pregnancies, of whom 76 (6.6%) had adverse neonatal outcome. Parity (primipara OR 2.75), BMI (OR 1.06), proteinuria (dipstick +++ OR 2.5), uric acid (OR 1.4) and creatinine (OR 1.02) were independent antepartum predictors; In the intrapartum model, meconium stained amniotic fluid (OR 2.2), temperature (OR 1.8), duration of first stage of labour (OR 1.15), proteinuria (dipstick +++ OR 2.7), creatinine (OR 1.02) and uric acid (OR 1.5) were predictors of adverse neonatal outcome. Both models showed good discrimination (AUC 0.75 and 0.78), but calibration was limited (Hosmer-Lemeshow p = 0.41, and p = 0.20). CONCLUSIONS In women with GH or PE at term, it is difficult to predict neonatal complications, possibly since they are rare in the term pregnancy. However, the identified individual predictors may guide physicians to anticipate requirements for neonatal care.
