ObjectiveTo compare the costs of induction of labor and expectant management in women with preterm prelabor rupture of membranes (PPROM).DesignEconomic analysis based on a randomized clinical trial.SettingObstetric departments of eight academic and 52 non-academic hospitals in the Netherlands.PopulationWomen with PPROM near term who were not in labor 24h after PPROM.MethodsA cost-minimization analysis was done from a health care provider perspective, using a bottom-up approach to estimate resource utilization, valued with unit-costs reflecting actual costs.Main outcome measuresPrimary health outcome was the incidence of neonatal sepsis. Direct medical costs were estimated from start of randomization to hospital discharge of mother and child.ResultsInduction of labor did not significantly reduce the probability of neonatal sepsis [2.6% vs. 4.1%, relative risk 0.64 (95% confidence interval 0.25-1.6)]. Mean costs per woman were Euro8094 for induction and Euro7340 for expectant management (difference Euro754; 95% confidence interval -335 to 1802). This difference predominantly originated in the postpartum period, where the mean costs were Euro5669 for induction vs. Euro4801 for expectant management. Delivery costs were higher in women allocated to induction than in women allocated to expectant management (Euro1777 vs. Euro1153 per woman). Antepartum costs in the expectant management group were higher because of longer antepartum maternal stays in hospital.ConclusionsIn women with pregnancies complicated by PPROM near term, induction of labor does not reduce neonatal sepsis, whereas costs associated with this strategy are probably higher.

To assess effectiveness and safety of Foley catheter versus vaginal misoprostol for term induction of labor. This trial randomly allocated women with singleton term pregnancy to 30-mL Foley catheter or 25-μg vaginal misoprostol tablets. Primary outcome was cesarean delivery rate. Secondary outcomes were maternal and neonatal morbidity and time to birth. Additionally, a systematic review was conducted. Fifty-six women were allocated to Foley catheter, 64 to vaginal misoprostol tablets. Cesarean delivery rates did not differ significantly (25% Foley versus 17% misoprostol; relative risk [RR] 1.46, 95% confidence interval [CI] 0.72 to 2.94), with more cesarean deliveries due to failure to progress in the Foley group (14% versus 3%; RR 4.57, 95% CI 1.01 to 20.64). Maternal and neonatal outcomes were comparable. Time from induction to birth was longer in the Foley catheter group (36 hours versus 25 hours; p < 0.001). Meta-analysis showed no difference in cesarean delivery rate and reduced vaginal instrumental deliveries and hyperstimulation in the Foley catheter group. Other outcomes were not different. Our trial and meta-analysis showed no difference in cesarean delivery rates and less hyperstimulation with fetal heart rate changes and vaginal instrumental deliveries when using Foley catheter, thereby supporting potential advantages of the Foley catheter over misoprostol as ripening agent

Contains fulltext : 118626.pdf (Publisher’s version ) (Open Access) BACKGROUND: Prognostic models in reproductive medicine can help to identify subfertile couples who would benefit from fertility treatment. Expectant management in couples with a good chance of natural conception, i.e., tailored expectant management (TEM), prevents unnecessary treatment and is therefore recommended in international fertility guidelines. However, current implementation is not optimal, leaving room for improvement. Based on barriers and facilitators for TEM that were recently identified among professionals and subfertile couples, we have developed a multifaceted implementation strategy. The goal of this study is to assess the effects of this implementation strategy on the guideline adherence on TEM. METHODS/DESIGN: In a cluster randomized trial, 25 clinics and their allied practitioners units will be randomized between the multifaceted implementation strategy and care as usual. Randomization will be stratified for in vitro fertilization (IVF) facilities (full licensed, intermediate/no IVF facilities). The effect of the implementation strategy, i.e., the percentage guideline adherence on TEM, will be evaluated by pre- and post-randomization data collection. Furthermore, there will be a process and cost evaluation of the strategy. The implementation strategy will focus on subfertile couples and their care providers i.e., general practitioners (GPs), fertility doctors, and gynecologists. The implementation strategy addresses three levels: patient level: education materials in the form of a patient information leaflet and a website; professional level: audit and feedback, educational outreach visit, communication training, and access to a digital version of the prognostic model of Hunault on a website; organizational level: providing a protocol based on the guideline. The primary outcome will be the percentage guideline adherence on TEM. Additional outcome measures will be treatment-, patient-, and process-related outcome measures. DISCUSSION: This study will provide evidence about the effectiveness and costs of a multifaceted implementation strategy to improve guideline adherence on TEM.

Item does not contain fulltext OBJECTIVE: The evidence for the management of near term prelabor rupture of membranes is poor. From January 2007 until September 2009, we performed the PPROM Expectant Management versus Induction of Labor (PPROMEXIL) trial. In this trial, we showed that in women with preterm prelabor rupture of membranes (PPROM), the incidence of neonatal sepsis was low, and the induction of labor (IoL) did not reduce this risk. Because the PPROMEXIL trial was underpowered and because of a lower-than-expected incidence of neonatal sepsis, we performed a second trial (PPROMEXIL-2), aiming to randomize 200 patients to improve the evidence in near-term PPROM. STUDY DESIGN: In a nationwide multicenter study, nonlaboring women with PPROM between 34 and 37 weeks' gestational age were eligible for inclusion. Patients were randomized to IoL or expectant management (EM). The primary outcome measure was neonatal sepsis. RESULTS: From December 2009 until January 2011, we randomized 100 women to IoL and 95 to EM. Neonatal sepsis was seen in 3 neonates (3.0%) in the IoL-group versus 4 neonates (4.1%) in the EM group (relative risk, 0.74; 95% confidence interval, 0.17-3.2). One of the sepsis cases in the IoL group resulted in neonatal death because of asphyxia. There were no significant differences in secondary outcomes. CONCLUSION: The risk of neonatal sepsis after PPROM near term is low. Induction of labor does not reduce this risk.

preterm recurrence ,severe ,Pre-eclampsia - Abstract
Objective The aim of this study was to report outcomes of the subsequent pregnancy after early-onset pre-eclampsia in a first pregnancy (index), and to evaluate the potential risk factors for recurrence of pre-eclampsia and preterm delivery. Design We performed a retrospective cohort study of all women who developed early-onset pre-eclampsia (delivery before 34 weeks of gestation) in their first pregnancy between January 1996 and December 2004 in two perinatal centres with regional function. All patients were included consecutively. Information was retrieved on the course of subsequent pregnancies. Setting Two tertiair centres with regional function. Population Women with a delivery under 34 weeks due to a hypertensive disorder (N = 380). Main outcome measures We determined the absolute risk of recurrence of an adverse outcome, defined as a hypertensive complication resulting in delivery before 34 weeks of gestation. The available clinical parameters were evaluated as predictors for recurrence using logistic regression analysis. Results We identified 380 patients, of whom 46 were lost to follow-up. In total, 123 patients refrained from subsequent pregnancy (79 [64%] from fear of recurrence). Of the 211 patients with a subsequent pregnancy, 36 (17%, 95% CI 12-22%) had a recurrent delivery before 34 weeks of gestation, 30 (14%, 95% CI 9.5-19%) delivered between 34 and 37 weeks of gestation, and 145 (69%, 95% CI 62-75%) delivered later than 37 weeks of gestation. Of this last group, only 67 (32%, 95% CI 25-38%) pregnancies were completely uneventful. Chronic hypertension, maximum diastolic blood pressure, caesarean delivery and level of 24-h proteinuria were independent predictors for an adverse pregnancy outcome. Conclusions Women that had early severe pre-eclampsia in their first pregnancy have a 17% risk of recurrence, with a delivery before 34 weeks of gestation. Only 32% had a completely uneventful pregnancy.

- Abstract
OBJECTIVE: The objective of the study was to determine the neonatal morbidity in late preterm infants born from mothers with a hypertensive disorder. STUDY DESIGN: Data were obtained from the national Perinatal Registry in The Netherlands on women who delivered between 34(+0) and 36(+6) weeks with gestational hypertension (n = 4316), preeclampsia (n = 1864), and normotensive controls (n = 20,749). RESULTS: Children from mothers with preeclampsia had an increased risk for admission to the neonatal intensive care unit compared with children from normotensive mothers (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.8-2.2). A cesarean delivery and decreasing gestational age were independent risk factors for neonatal respiratory morbidity. Gestational hypertension or preeclampsia reduced the risk of respiratory distress syndrome compared with the control group (OR, 0.81; 95% CI, 0.64-1.0 and OR, 0.69; 95% CI, 0.49-0.96, respectively). CONCLUSION: Neonatal morbidity in the late preterm period is considerable. Hypertensive disorders appear to protect for neonatal respiratory morbidity, but higher rates of cesarean section diminish this protective effect.

Contains fulltext : 96419.pdf (Publisher’s version ) (Closed access) AIMS: To determine the reclassification rate of clinically diagnosed stress, mixed, and urge urinary incontinence after urodynamic investigation. METHODS: A systematic review of the published literature in MEDLINE and EMBASE of clinical trials among women with urinary incontinence. Studies were included in case the diagnosis based on symptoms and/or signs was compared with the diagnosis after urodynamic investigation. RESULTS: Twenty-three articles involving 6,282 women with urinary incontinence met the inclusion criteria. A clinical diagnosis of stress urinary incontinence was reclassified into mixed urinary incontinence in 9% of women and into detrusor overactivity (DO) in 7% of cases. The pooled reclassification rate was highest among patients with symptoms of mixed urinary incontinence, where 46% of the patients had stress urinary incontinence and 21% had DO on urodynamic investigation. The available literature does not allow the identification of the additional value of non-invasive test, such as stress test and voiding diary, accessory to symptoms. None of the studies had therapeutic effects as an outcome measure. CONCLUSIONS: This review of clinical studies shows that the level of agreement between classification based on clinical evaluation and based on urodynamic investigation is poor. Urodynamic observations are regarded as gold standard, but based on the poor correlation, this assumption should be questioned.

- Abstract
Contains fulltext : 153200.pdf (publisher's version ) (Open Access), BACKGROUND: A large number of studies have shown an association between inherited thrombophilia and recurrent miscarriage. It has been hypothesized that anticoagulant therapy might reduce the number of miscarriages and stillbirth in these women. In the absence of randomized controlled trials evaluating the efficacy of anticoagulant therapy in women with inherited thrombophilia and recurrent miscarriage, a randomized trial with adequate power that addresses this question is needed. The objective of the ALIFE2 study is therefore to evaluate the efficacy of low-molecular-weight heparin (LMWH) in women with inherited thrombophilia and recurrent miscarriage, with live birth as the primary outcome. METHODS/DESIGN: Randomized study of LMWH plus standard pregnancy surveillance versus standard pregnancy surveillance alone. STUDY POPULATION: pregnant women of less than 7 weeks' gestation, and confirmed inherited thrombophilia with a history of 2 or more miscarriages or intra-uterine fetal deaths, or both. SETTING: multi-center study in centers from the Dutch Consortium of Fertility studies; centers outside the Netherlands are currently preparing to participate. INTERVENTION: LMWH enoxaparin 40 mg subcutaneously once daily started prior to 7 weeks gestational age plus standard pregnancy surveillance or standard pregnancy surveillance alone. Main study parameters/endpoints: the primary efficacy outcome is live birth. Secondary efficacy outcomes include adverse pregnancy outcomes, such as miscarriage, pre-eclampsia, syndrome of hemolysis, elevated liver enzymes and low platelets (HELLP syndrome), fetal growth restriction, placental abruption, premature delivery and congenital malformations. Safety outcomes include bleeding episodes, thrombocytopenia and skin reactions. DISCUSSION: After an initial period of slow recruitment, the recruitment rate for the study has increased. Improved awareness of the study and acknowledgement of the need for evidence are thought to be contributin

- Abstract
Item does not contain fulltext, OBJECTIVE: To assess the impact of cervical length (CL) measurement and fetal fibronectin testing (fFN) on the clinicians' decision to prescribe antenatal corticosteroids (ACS) to women with symptoms of preterm labor. STUDY DESIGN: This is a secondary analysis of a prospective cohort study including women with symptoms of preterm labor and intact membranes between 24 and 34 weeks' gestation. We compared the proportion prescribed and completed ACS courses, preterm delivery within seven days and median intervals from ACS to delivery in four groups: group 1 CL<10mm, group 2 CL 10-30mm and positive fFN, group 3 CL 10-30mm and negative fFN, group 4 CL>30mm. RESULTS: ACS were prescribed to 63/65 (97%) women in group 1, 176/192 (91%) in group 2, 111/172 women (65%) in group 3 and 55/242 (23%) in group 4. In group 1, 42 (65%) women delivered within seven days, compared to 34 (18%) in group 2, 6 (3%) in group 3 and 3 (1%) in group 4. Median intervals between ACS and delivery were 6 days (IQR 3-61 days), 44 days (IQR 17-69 days), 53 days (IQR 37-77 days) and 66 days (IQR 43-78 days) in group 1, 2, 3 and 4 respectively. CONCLUSION: ACS were prescribed frequently to women with a CL of 10-30mm and a negative fFN test or a CL>30mm. There is room for improvement in the prescription of ACS in these low risk women.

MATERIAL AND METHODS: We performed a prospective observational cohort study in nulliparous women and low-risk multiparous women with a singleton pregnancy between 16(+0) and 21(+6) weeks of gestation. We assessed the prognostic capacity of transvaginally measured mid-trimester CL for spontaneous and iatrogenic preterm birth (<37 weeks) using likelihood ratios (LR) and receiver-operating-characteristic analysis. We calculated numbers needed to screen to prevent one preterm birth assuming different treatment effects. Main outcome measures were preterm birth <32, <34 and <37 weeks. RESULTS: We studied 11 943 women, of whom 666 (5.6%) delivered preterm: 464 (3.9%) spontaneous and 202 (1.7%) iatrogenic. Mean CL was 44.1 mm (SD 7.8 mm). In nulliparous women, the LRs for spontaneous preterm birth varied between 27 (95% CI 7.7-95) for a CL = 20 mm, and 2.0 (95% CI 1.6-2.5) for a CL between 30 and 35 mm. For low-risk multiparous women, these LRs were 37 (95% CI 7.5-182) and 1.5 (95% CI 0.97-2.2), respectively. Using a cut-off for CL = 30 mm, 28 (6.0%) of 464 women with spontaneous preterm birth were identified. The number needed to screen to prevent one case of preterm birth was 618 in nulliparous women and 1417 for low-risk multiparous women (40% treatment effect, cut-off 30 mm). CONCLUSION: In women at low risk of preterm birth, CL predicts spontaneous preterm birth. However, its isolated use as a screening tool has limited value due to low sensitivity.

- Abstract
Contains fulltext : 152606.pdf (publisher's version ) (Open Access), Objective The aim of this study was to assess which characteristics and results of vaginal examination are predictive for delivery within 7 days, in women with threatened preterm labor after initial treatment. Study Design A secondary analysis of a randomized controlled trial on maintenance nifedipine includes women who remained undelivered after threatened preterm labor for 48 hours. We developed one model for women with premature prelabor rupture of membranes (PPROM) and one without PPROM. The predictors were identified by backward selection. We assessed calibration and discrimination and used bootstrapping techniques to correct for potential overfitting. Results For women with PPROM (model 1), nulliparity, history of preterm birth, and vaginal bleeding were included in the multivariable analysis. For women without PPROM (model 2), maternal age, vaginal bleeding, cervical length, and fetal fibronectin (fFN) status were in the multivariable analysis. Discriminative capability was moderate to good (c-statistic 0.68; 95% confidence interval [CI] 0.60-0.77 for model 1 and 0.89; 95% CI, 0.84-0.93 for model 2). Conclusion PPROM and vaginal bleeding in the current pregnancy are relevant predictive factors in all women, as are maternal age, cervical length, and fFN in women without PPROM and nulliparity, history of preterm birth in women with PPROM.

- Abstract
Item does not contain fulltext, STUDY QUESTION: What is the percentage of overtreatment, i.e. fertility treatment started too early, in couples with unexplained infertility who were eligible for tailored expectant management? SUMMARY ANSWER: Overtreatment occurred in 36% of couples with unexplained infertility who were eligible for an expectant management of at least 6 months. WHAT IS KNOWN ALREADY: Prognostic models in reproductive medicine can help to identify infertile couples that would benefit from fertility treatment. In couples with unexplained infertility with a good chance of natural conception within 1 year, based on the Hunault prediction model, an expectant management of 6-12 months, as recommended in international fertility guidelines, prevents unnecessary treatment. STUDY DESIGN, SIZE, DURATION: A retrospective cohort study in 25 participating clinics, with follow-up of all couples who were seen for infertility in 2011-2012. PARTICIPANTS/MATERIALS, SETTING, METHODS: In all, 9818 couples were seen for infertility in the participating clinics. Couples were eligible to participate if they were diagnosed with unexplained infertility and had a good prognosis of natural conception (>30%) within 1 year based on the Hunault prediction model. Data to assess overtreatment were collected from medical records. Multilevel regression analyses were performed to investigate associations of overtreatment with patient and clinic characteristics. MAIN RESULTS AND THE ROLE OF CHANCE: Five hundred and forty-four couples eligible for expectant management were included in this study. Among these, overtreatment, i.e. starting medically assisted reproduction within 6 months, occurred in 36%. The underlying quality indicators showed that in 34% no prognosis was calculated and that in 42% expectant management was not recommended. Finally, 16% of the couples for whom a correct recommendation of expectant management for at least 6 months was made, started treatment within 6 months anyway. Overtreatment was assoc

- Abstract
Contains fulltext : 153080.pdf (Publisher’s version ) (Closed access), INTRODUCTION: The APOSTEL-II trial was a multicenter randomized placebo-controlled trial, assessing the effectiveness of maintenance tocolysis with nifedipine. The trial showed maintenance tocolysis not to have an effect on perinatal outcome. Objective of the current study is to evaluate the effect of a negative trial on the length of hospital admission of women with threatened preterm labor. MATERIALS AND METHODS: We evaluated length of hospital admission of all patients admitted with threatened preterm labor with a gestational age <32 weeks in 8 perinatal centers that participated in the APOSTEL-II trial. We studied only the first admission with threatened preterm labor, readmissions were excluded. We distinguished between the period before, the period during and the period after the trial. In a subgroup analysis, we differentiated for the group of women who delivered and for the group of women who did not deliver during the initial admission. RESULTS: The mean length of hospital admission was 9.3 days before the start of the trial, 8.4 days during the recruitment period and 8.1 days after the trial was completed. The difference in mean length of hospital admission before and during the recruitment period was significantly different (p<001). COMMENTS: The length of hospital admission of women with threatened preterm labor is found to be reduced during the recruitment period of the APOSTEL-II trial. This shows that the conduct of a randomized controlled trial itself has the potential to change daily practice.

- Abstract
Item does not contain fulltext, OBJECTIVE: To determine whether second-trimester cervical length (CL) in women with a twin pregnancy is associated with the risk of emergency Cesarean section. METHODS: This was a secondary analysis of two randomized trials conducted in 57 hospitals in The Netherlands. We assessed the univariable association between risk indicators, including second-trimester CL in quartiles, and emergency Cesarean delivery using a logistic regression model. For multivariable analysis, we assessed whether adjustment for other risk indicators altered the associations found in univariable (unadjusted) analysis. Separate analyses were performed for suspected fetal distress and failure to progress in labor as indications for Cesarean section. RESULTS: In total, 311 women with a twin pregnancy attempted vaginal delivery after 34 weeks' gestation. Emergency Cesarean delivery was performed in 111 (36%) women, of which 67 (60%) were performed owing to arrest of labor. There was no relationship between second-trimester CL and Cesarean delivery (adjusted odds ratio (aOR): 0.97 for CL 26(th) -50(th) percentiles; 0.71 for CL 51(st) - 75(th) percentiles; and 0.92 for CL > 75(th) percentile, using CL = 25(th) percentile as reference). In multivariable analysis, the only variables associated with emergency Cesarean delivery were maternal age (aOR, 1.07 (95% CI, 1.00-1.13)), body mass index (BMI) (aOR, 3.99 (95% CI, 1.07-14.9) for BMI 20-23 kg/m(2) ; 5.04 (95% CI, 1.34-19.03) for BMI 24-28 kg/m(2) ; and 3.1 (95% CI, 0.65-14.78) for BMI > 28 kg/m(2) ) and induction of labor (aOR, 1.92 (95% CI, 1.05-3.5)). CONCLUSION: In nulliparous women with a twin pregnancy, second-trimester CL is not associated with risk of emergency Cesarean delivery. Copyright (c) 2014 ISUOG. Published by John Wiley & Sons Ltd.

- Abstract
Contains fulltext : 153600.pdf (Publisher’s version ) (Open Access), OBJECTIVE: To determine women's satisfaction with pain relief using patient controlled analgesia with remifentanil compared with epidural analgesia during labour. DESIGN: Multicentre randomised controlled equivalence trial. SETTING: 15 hospitals in the Netherlands. PARTICIPANTS: Women with an intermediate to high obstetric risk with an intention to deliver vaginally. To exclude a clinically relevant difference in satisfaction with pain relief of more than 10%, we needed to include 1136 women. Because of missing values for satisfaction this number was increased to 1400 before any analysis. We used multiple imputation to correct for missing data. INTERVENTION: Before the onset of active labour consenting women were randomised to a pain relief strategy with patient controlled remifentanil or epidural analgesia if they requested pain relief during labour. MAIN OUTCOME MEASURES: Primary outcome was satisfaction with pain relief, measured hourly on a visual analogue scale and expressed as area under the curve (AUC), thus providing a time weighted measure of total satisfaction with pain relief. A higher AUC represents higher satisfaction with pain relief. Secondary outcomes were pain intensity scores, mode of delivery, and maternal and neonatal outcomes. Analysis was done by intention to treat. The study was defined as an equivalence study for the primary outcome. RESULTS: 1414 women were randomised, of whom 709 were allocated to patient controlled remifentanil and 705 to epidural analgesia. Baseline characteristics were comparable. Pain relief was ultimately used in 65% (447/687) in the remifentanil group and 52% (347/671) in the epidural analgesia group (relative risk 1.32, 95% confidence interval 1.18 to 1.48). Cross over occurred in 7% (45/687) and 8% (51/671) of women, respectively. Of women primarily treated with remifentanil, 13% (53/402) converted to epidural analgesia, while in women primarily treated with epidural analgesia 1% (3/296) converted to remifentanil. T

- Abstract
Item does not contain fulltext, OBJECTIVE: To assess adherence to expectant management of 6-12 months in couples with unexplained subfertility, as recommended by the Dutch Networkguideline Subfertility. DESIGN: A retrospective cohort study in 25 clinics. METHOD: Couples were eligible to participate if they were diagnosed with unexplained subfertility and had a good prognosis of natural conception within one year (>30%), for these couples the network guideline recommends an expectant management. Outcomes measures are overtreatment, i.e. couples that started treatment within six months, and three quality indicators: 1) prognosis not calculated, 2) no correct expectant management advised, 3) starting treatment too soon despite a correct advise. Data collection was obtained from medical records. Multilevel regression analyses were performed to investigate associations of overtreatment with patient and clinic characteristics. RESULTS: We included 544 couples. Overtreatment occurred in 36% (N=198). In 34% (N=186) of all couples no prognosis was calculated (1), and in 42% (N=230) of all couples expectant management was not advised correctly (2). When a correct expectant management of six to twelve months was advised, 16% (N=51) started treatment too soon anyway. Overtreatment occurred more frequently in childless couples, a higher female age, and a longer duration of infertility. CONCLUSION: Our findings show that developing and publishing guideline recommendations on expectant management is not enough and that overtreatment still occurs frequently. To improve future care the next step is to evaluate a tailored implementation strategy to improve adherence to the recommendations on expectant management by the Dutch Networkguideline Subfertility.

- Abstract
Item does not contain fulltext, Objective The objective of this study was to evaluate the effectiveness of vaginal progesterone in reducing adverse neonatal outcome due to preterm birth (PTB) in low-risk pregnant women with a short cervical length (CL). Study Design Women with a singleton pregnancy without a history of PTB underwent CL measurement at 18 to 22 weeks. Women with a CL = 30 mm received vaginal progesterone or placebo. Primary outcome was adverse neonatal outcome, defined as a composite of respiratory distress syndrome, bronchopulmonary dysplasia, intracerebral hemorrhage > grade II, necrotizing enterocolitis > stage 1, proven sepsis, or death before discharge. Secondary outcomes included time to delivery, PTB before 32, 34, and 37 weeks of gestation. Analysis was by intention to treat. Results Between 2009 and 2013, 20,234 women were screened. A CL of 30 mm or less was seen in 375 women (1.8%). In 151 women, a CL = 30 mm was confirmed with a second measurement and 80 of these women agreed to participate in the trial. We randomly allocated 41 women to progesterone and 39 to placebo. Adverse neonatal outcomes occurred in two (5.0%) women in the progesterone and in four (11%) women in the control group (relative risk [RR], 0.47; 95% confidence interval [CI], 0.09-2.4). The use of progesterone resulted in a nonsignificant reduction of PTB < 32 weeks (2.0 vs. 8.0%; RR, 0.33; 95% CI, 0.04-3.0) and < 34 weeks (7.0 vs. 10%; RR, 0.73; 95% CI, 0.18-3.1) but not on PTB < 37 weeks (15 vs. 13%; RR, 1.2; 95% CI, 0.39-3.5). Conclusion In women with a short cervix, who are otherwise low risk, we could not show a significant benefit of progesterone in reducing adverse neonatal outcome and PTB.

- Abstract
Item does not contain fulltext, OBJECTIVE: To assess whether patient characteristics add to the fetal fibronectin test and cervical length measurement in the prediction of preterm delivery in symptomatic women. STUDY DESIGN: A nationwide prospective cohort study was conducted in all ten perinatal centres in the Netherlands. Women with symptoms of preterm labour between 24 and 34 weeks gestation with intact membranes were invited. In all women qualitative fibronectin testing (0.050mug/mL cut-off) and cervical length measurement were performed. Only singleton pregnancies were included in this analysis. Logistic regression was used to construct two multivariable models to predict spontaneously delivery within 7 days: a model including cervical length and fetal fibronectin as predictors, and an extended model including all potential predictors. The models were internally validated using bootstrapping techniques. Predictive performances were assessed as the area under the receiver operator characteristic curve (AUC) and calibration plots. We compared the models' capability to identify women with a low risk to deliver within 7 days. A risk less than 5%, corresponding to the risk for women with a cervical length of at least 25mm, was considered as low risk. RESULTS: Seventy-three of 600 included women (12%) had delivered spontaneously within 7 days. The extended model included maternal age, parity, previous preterm delivery, vaginal bleeding, C-reactive protein, cervical length, dilatation and fibronectin status. Both models had high discriminative performances (AUC of 0.92 (95% CI 0.88-0.95) and 0.95 (95% CI 0.92-0.97) respectively). Compared to the model with fibronectin and cervical length, our extended model reclassified 38 women (6%) from low risk to high risk and 21 women (4%) from high risk to low risk. Preterm delivery within 7 days occurred once in both the reclassification groups. CONCLUSION: In women with symptoms of preterm labour before 34 weeks gestation, a model that integrates maternal ch

Contains fulltext : 152137.pdf (publisher's version ) (Open Access), OBJECTIVE: To evaluate whether a model to predict a failed endometrial biopsy in women with postmenopausal bleeding (PMB) and a thickened endometrium can reduce costs without compromising diagnostic accuracy. DESIGN, SETTING, AND POPULATION: Model based cost-minimization analysis. METHODS: A decision analytic model was designed to compare two diagnostic strategies for women with PMB: (I) attempting office endometrial biopsy and performing outpatient hysteroscopy after failed biopsy and (II) predicted probability of a failed endometrial biopsy based on patient characteristics to guide the decision for endometrial biopsy or immediate hysteroscopy. Robustness of assumptions regarding costs was evaluated in sensitivity analyses. MAIN OUTCOME MEASURES: Costs for the different strategies. RESULTS: At different cut-offs for the predicted probability of failure of an endometrial biopsy, strategy I was generally less expensive than strategy II. The costs for strategy I were always euro 460; the costs for strategy II varied between euro 457 and euro 475. At a 65% cut-off, a possible saving of euro 3 per woman could be achieved. CONCLUSIONS: Individualizing the decision to perform an endometrial biopsy or immediate hysteroscopy in women presenting with postmenopausal bleeding based on patient characteristics does not increase the efficiency of the diagnostic work-up.

- Abstract
Contains fulltext : 154037.pdf (publisher's version ) (Open Access), BACKGROUND: The four approaches to hysterectomy for benign disease are abdominal hysterectomy (AH), vaginal hysterectomy (VH), laparoscopic hysterectomy (LH) and robotic-assisted hysterectomy (RH). OBJECTIVES: To assess the effectiveness and safety of different surgical approaches to hysterectomy for women with benign gynaecological conditions. SEARCH METHODS: We searched the following databases (from inception to 14 August 2014) using the Ovid platform: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PsycINFO. We also searched relevant citation lists. We used both indexed and free-text terms. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in which clinical outcomes were compared between one surgical approach to hysterectomy and another. DATA COLLECTION AND ANALYSIS: At least two review authors independently selected trials, assessed risk of bias and performed data extraction. Our primary outcomes were return to normal activities, satisfaction, quality of life, intraoperative visceral injury and major long-term complications (i.e. fistula, pelvi-abdominal pain, urinary dysfunction, bowel dysfunction, pelvic floor condition and sexual dysfunction). MAIN RESULTS: We included 47 studies with 5102 women. The evidence for most comparisons was of low or moderate quality. The main limitations were poor reporting and imprecision. Vaginal hysterectomy (VH) versus abdominal hysterectomy (AH) (nine RCTs, 762 women)Return to normal activities was shorter in the VH group (mean difference (MD) -9.5 days, 95% confidence interval (CI) -12.6 to -6.4, three RCTs, 176 women, I(2) = 75%, moderate quality evidence). There was no evidence of a difference between the groups for the other primary outcomes. Laparoscopic hysterectomy (LH) versus AH (25 RCTs, 2983 women)Return to normal activities was shorter in the LH group (MD -13.6 days, 95% CI -15.4 to -11.8; six RCTs, 520

- Abstract
Item does not contain fulltext, BACKGROUND: Existing approaches for the screening and treatment of asymptomatic bacteriuria in pregnancy are based on trials that were done more than 30 years ago. In this study, we reassessed the consequences of treated and untreated asymptomatic bacteriuria in pregnancy. METHODS: In this multicentre prospective cohort study with an embedded randomised controlled trial, we screened women (aged >/=18 years) at eight hospitals and five ultrasound centres in the Netherlands with a singleton pregnancy between 16 and 22 weeks' gestation for asymptomatic bacteriuria. Screening was done with a single dipslide and two culture media. Dipslides were judged positive when the colony concentration was at least 1x10(5) colony-forming units (CFU) per mL of a single microorganism or when two different colony types were present but one had a concentration of at least 1x10(5) CFU per mL. Asymptomatic bacteriuria-positive women were eligible to participate in the randomised controlled trial comparing nitrofurantoin with placebo treatment. In this trial, participants were randomly assigned 1:1 to receive either nitrofurantoin 100 mg or identical placebo tablets, and were instructed to self-administer these tablets twice daily for 5 consecutive days. Randomisation was done by a web-based application with a computer-generated list with random block sizes of two, four, or six participants rendered by an independent data manager. 1 week after the end of treatment, they provided us with a follow-up dipslide.

Women who refused to participate in the randomised controlled trial did not receive any antibiotics, but their outcomes were collected for analysis in the cohort study. We compared untreated and placebo-treated asymptomatic bacteriuria-positive women with asymptomatic bacteriuria-negative women and nitrofurantoin-treated asymptomatic bacteriuria-positive women.

- Abstract
Item does not contain fulltext, OBJECTIVE: We recently reported that induction of labour does not improve short term neonatal outcome in women with late preterm premature rupture of membranes (PPROM) as compared to expectant management (PPROMEXIL trial). In this study the neurodevelopmental and behavioural outcome of the children from this trial at 2 years of age was studied. STUDY DESIGN: We studied outcome of offspring of women randomised in the PPROMEXIL study. These women had >24h of ruptured membranes and were between 34 and 37 weeks of pregnancy when they were randomised to induction of labour (IoL) or expectant management (EM). Two years after delivery, the parents received the ages and stages questionnaire (ASQ), the child behaviour checklist (CBCL) and a general questionnaire. RESULTS: Follow-up data were obtained from 234 children (121 after IoL, 113 after EM, response rate 59% (44% of the original 532 randomised women)). In the IoL group 16 children (14%) had an abnormal score in >/=1 domains of the ASQ, versus 27 (26%) in the EM group (difference in percentage -11.4 (95% CI -21.9 to -0.98; p=0.033)). For the CBCL, an abnormal score was found in 13% (n=15) in the IoL group and in 15% (n=16) in the EM group (difference in percentage -2.13 (95% CI -11.2 to 6.94; p=0.645)). CONCLUSION: Although a policy of induction of labour in women with late PPROM does not improve short term neonatal outcome, it might be associated with a decrease in neurodevelopmental difficulties at the age of two years as compared to expectant management. Expectant management did not lead to a difference in behavioural problems.

- Abstract
Item does not contain fulltext, OBJECTIVE: To stratify the risk of spontaneous preterm delivery using cervical length (CL) and fetal fibronectin (fFN) in women with threatened preterm labor who remained pregnant after 7 days. DESIGN: Prospective observational study. SETTING: Nationwide cohort of women with threatened preterm labor from the Netherlands. POPULATION: Women with threatened preterm labor between 24 and 34 weeks with a valid CL and fFN measurement and remaining pregnant 7 days after admission. METHODS: Kaplan-Meier and Cox proportional hazards models were used to estimate cumulative percentages and hazard ratios (HR) for spontaneous delivery. MAIN OUTCOME MEASURES: Spontaneous delivery between 7 and 14 days after initial presentation and spontaneous preterm delivery before 34 weeks. RESULTS: The risk of delivery between 7 and 14 days was significantly increased for women with a CL < 15 mm or a CL >/=15 to <30 mm and a positive fFN, compared with women with a CL >/=30 mm: HR 22.3 [95% confidence interval (CI) 2.6-191] and 14 (95% CI 1.8-118), respectively. For spontaneous preterm delivery before 34 weeks the risk was increased for women with a CL < 15 mm [HR 6.3 (95% CI 2.6-15)] or with a CL >/=15 to <30 mm with either positive fFN [HR 3.6 (95% CI 1.5-8.7)] or negative fFN [HR 3.0 (95% CI 1.2-7.1)] compared with women with a CL >/= 30 mm. CONCLUSIONS: In women remaining pregnant 7 days after threatened preterm labor, CL and fFN results can be used in risk stratification for spontaneous delivery.

- Abstract
Item does not contain fulltext, Objective Cervical length (CL) is associated with the risk of preterm birth (PTB) in multiple pregnancies. However, the position of CL within the pathophysiological pathway of PTB is unclear, and it is unknown which factors are predictive for CL. This study aims to investigate whether in twin pregnancies baseline maternal and obstetrical characteristics are potential indicators for CL, to improve insight in the pathophysiological pathway of PTB. Study Design Secondary analysis of data on twin pregnancies and CL measurement between 16 and 22 weeks. A set of 10 potential indicators, known to be associated with an increased risk of PTB and/or which have a plausible mechanism resulting in a change of CL were selected. We used multivariable linear regression with backward selection to identify independent indicators for CL. Results A total of 1,447 women with twin pregnancies were included. Mean CL was 43.7 (+/- 8.9) mm. In multivariable analysis, age (0.27 mm/y; 95% confidence interval [CI] 0.16 to 0.39), use of assisted reproductive technologies (ART) (-1.42 mm, 95% CI -2.6 to -0.25), and having delivered at term in a previous pregnancy (1.32 mm, 95% CI 0.25 to 2.39) were significantly associated with CL. Conclusion This study shows that in twin pregnancies, age, use of ART and having delivered term in a previous pregnancy has an association with CL.

- Abstract
Contains fulltext : 153218.pdf (publisher's version ) (Closed access), BACKGROUND: In the Dutch maternity care system, primary care midwives provide care to low-risk women and refer to obstetricians if risks or complications occur. We examined reasons for referral, management of labor, and maternal and neonatal outcomes among women who were referred during labor. METHODS: In a retrospective cohort study, descriptive analyses were performed on data obtained from patient records. Six purposively chosen hospitals in The Netherlands participated in the study from June 2011 to February 2012. The study population included 600 pregnant women who were referred during labor from primary to secondary care. MAIN OUTCOME MEASURES: Reasons for referral, interventions after referral, mode of delivery, and maternal and neonatal outcomes. RESULTS: Of women who were referred during labor, three out of four women were referred for moderate risk indications: request for pain relief (30.5%), meconium-stained liquor (25.3%), failure to progress during first stage of labor (14.0%), and prolonged ruptured membranes without contractions (12.5%). Of all women, 65.7 percent had a spontaneous vaginal delivery and 59.7 percent received some kind of pain relief. Acute referral, meaning fetal distress, occurred in 5.5 percent. Of the newborns, 2.7 percent had an Apgar score of 7 or less after 5 minutes and 1.2 percent had an umbilical cord pH < 7.05. Postpartum complications occurred among 11.0 percent of women. CONCLUSION: Women who are referred during labor have a high probability of spontaneous vaginal delivery. To improve continuity of care and satisfaction for this group of women, management of labor could be continued by trained primary care midwives.

- Abstract
Item does not contain fulltext, STUDY QUESTION: What are the pregnancy outcomes for women with a twin pregnancy that is reduced to a singleton pregnancy? SUMMARY ANSWER: Fetal reduction of a twin pregnancy significantly improves gestational age at birth and neonatal birthweight, however at an increased risk of pregnancy loss and preterm delivery. WHAT IS KNOWN ALREADY: Women with a multiple pregnancy are at increased risk for preterm delivery. Fetal reduction can be considered in these women. STUDY DESIGN, SIZE, AND DURATION: Retrospective cohort study of 118 women with a twin pregnancy reduced to a singleton pregnancy between 2000 and 2010. PARTICIPANTS/MATERIALS, SETTING, AND METHODS: We compared the outcome of pregnancy in consecutive women with a dichorionic twin pregnancy that was reduced to a singleton pregnancy to that of women with a dichorionic twin pregnancy that was managed expectantly and women with a primary singleton pregnancy. Reductions were performed between 10-23(6/7) weeks' gestation by intracardiac or intrathoracic injection of potassium chloride, mostly for congenital anomalies. We compared median gestational age, pregnancy loss <24 weeks, preterm delivery <32 weeks, neonatal birthweight and perinatal deaths. MAIN RESULTS AND THE ROLE OF CHANCE: We studied 118 women with a twin pregnancy that was reduced to a singleton, 818 women with an ongoing dichorionic twin pregnancy and 611 women with a primary singleton pregnancy. Loss of the entire pregnancy <24 weeks and preterm delivery occurred significantly more in the reduction group compared with the ongoing twin group (11.9 versus 3.1% <24 weeks, P< 0.001 and 18.6 versus 11.5% <32 weeks, respectively, P < 0.001). In the reduction group, the percentage of women without any surviving child was significantly higher compared with the ongoing twin and primary singleton group (14.4, 3.4 and 0.7%, respectively, P < 0.001). Median gestational age was 38.9 weeks (interquartile range (IQR) 34.7-40.3) for reduced pregnancies, 37.1 weeks (I

- Abstract
Item does not contain fulltext, BACKGROUND: There is little evidence to guide the management of women with hypertensive disorders in late preterm pregnancy. We investigated the effect of immediate delivery versus expectant monitoring on maternal and neonatal outcomes in such women. METHODS: We did an open-label, randomised controlled trial, in seven academic hospitals and 44 non-academic hospitals in the Netherlands. Women with non-severe hypertensive disorders of pregnancy between 34 and 37 weeks of gestation were randomly allocated to either induction of labour or caesarean section within 24 h (immediate delivery) or a strategy aimed at prolonging pregnancy until 37 weeks of gestation (expectant monitoring). The primary outcomes were a composite of adverse maternal outcomes (thromboembolic disease, pulmonary oedema, eclampsia, HELLP syndrome, placental abruption, or maternal death), and neonatal respiratory distress syndrome, both analysed by intention-to-treat. This study is registered with the Netherlands Trial Register (NTR1792). FINDINGS: Between March 1, 2009, and Feb 21, 2013, 897 women were invited to participate, of whom 703 were enrolled and randomly assigned to immediate delivery (n=352) or expectant monitoring (n=351). The composite adverse maternal outcome occurred in four (1.1%) of 352 women allocated to immediate delivery versus 11 (3.1%) of 351 women allocated to expectant monitoring (relative risk [RR] 0.36, 95% CI 0.12-1.11; p=0.069). Respiratory distress syndrome was diagnosed in 20 (5.7%) of 352 neonates in the immediate delivery group versus six (1.7%) of 351 neonates in the expectant monitoring group (RR 3.3, 95% CI 1.4-8.2; p=0.005). No maternal or perinatal deaths occurred. INTERPRETATION: For women with non-severe hypertensive disorders at 34-37 weeks of gestation, immediate delivery might reduce the already small risk of adverse maternal outcomes. However, it significantly increases the risk of neonatal respiratory distress syndrome, therefore, routine immediate delivery

- Abstract
Item does not contain fulltext, OBJECTIVE: To evaluate whether tocolysis with nifedipine can be omitted in women with symptoms of preterm labor, a shortened cervix, and negative fetal fibronectin test. STUDY DESIGN: A randomized noninferiority trial was performed in all Dutch perinatal centers. Women with symptoms of preterm labor between 24 and 34 weeks, intact membranes, cervical length between 10 and 30 mm, and negative fibronectin test were randomly allocated to nifedipine (80 mg/day) or placebo. The primary outcome was delivery within 7 days. Secondary outcomes were severe neonatal morbidity and mortality. We also followed all eligible nonrandomized women. RESULTS: We allocated 37 women to nifedipine and 36 women to placebo. In the nifedipine group, three women (8.1%) delivered within 7 days, compared with one woman (2.8%) in the placebo group (difference -5.3%; one-sided 95% confidence limit 4.5%). Median gestational age at delivery were respectively 37 + 0 (interquartile range [IQR] 34 + 6 to 38 + 5) and 38 + 2 (IQR 37 + 0 to 39 + 6) weeks (p = 0.008). In the nifedipine group, three pregnancies (8.1%) had a poor outcome; there were no poor outcomes in the placebo group. We observed similar trends in eligible nonrandomized women. CONCLUSION: In symptomatic women with preterm labor, a shortened cervix, and negative fibronectin test, placebo treatment is not inferior to tocolysis with nifedipine.
