RESUMEN
OBJECTIVE: To assess the association between ketonuria and hyperemesis gravidarum (HG) disease severity. STUDY DESIGN: We included pregnant women hospitalised for HG who participated in the Maternal and Offspring outcomes after Treatment of HyperEmesis by Refeeding (MOTHER) trial and women who were eligible, chose not to be randomised and agreed to participate in the observational cohort. Between October 2013 and March 2016, in 19 hospitals in the Netherlands, women hospitalised for HG were approached for study participation. The presence of ketonuria was not required for study entry. Ketonuria was measured at hospital admission with a dipstick, which distinguishes 5 categories: negative and 1+ through 4 + . The outcome measures were multiple measures of HG disease severity at different time points: 1) At hospital admission (study entry): severity of nausea and vomiting, quality of life and weight change compared to pre-pregnancy weight, 2) One week after hospital admission: severity of nausea and vomiting, quality of life and weight change compared to admission, 3) Duration of index hospital admission and readmission for HG at any time point RESULTS: 215 women where included. Ketonuria was not associated with severity of nausea and vomiting, quality of life or weight loss at hospital admission, nor was the degree of ketonuria at admission associated with any of the outcomes 1 week after hospital admission. The degree of ketonuria was also not associated with the number of readmissions. However, women with a higher degree of ketonuria had a statistically significant longer duration of hospital stay (per 1+ ketonuria, difference: 0.27 days, 95 % CI: 0.05 to 0.48). CONCLUSIONS: There was no association between the degree of ketonuria at admission and severity of symptoms, quality of life, maternal weight loss, or number of readmissions, suggesting that ketonuria provides no information about disease severity or disease course. Despite this, women with a higher degree of ketonuria at admission were hospitalised for longer. This could suggest that health care professionals base length of hospital stay on the degree of ketonuria. Based on the lack of association between ketonuria and disease severity, we suggest it has no additional value in the clinical management of HG.

OBJECTIVE: To assess the costs of labour induction with oral misoprostol versus Foley catheter. DESIGN: Economic evaluation alongside a randomised controlled trial. SETTING: Obstetric departments of six tertiary and 23 secondary care hospitals in the Netherlands. POPULATION: Women with a viable term singleton pregnancy in cephalic presentation, intact membranes, an unfavourable cervix (Bishop score <6) without a previous caesarean section, were randomised for labour induction with oral misoprostol (n = 924) or Foley catheter (n = 921). METHODS: We performed economic analysis from a hospital perspective. We estimated direct medical costs associated with healthcare utilisation from randomisation until discharge. The robustness of our findings was evaluated in sensitivity analyses. MAIN OUTCOME MEASURES: Mean costs and differences were calculated per women induced with oral misoprostol or Foley catheter. RESULTS: Mean costs per woman in the oral misoprostol group and Foley catheter group were 4470 versus 4158, respectively [mean difference 312, 95% confidence interval (CI) -508 to 1063]. Multiple sensitivity analyses did not change these conclusions. However, if cervical ripening for low-risk pregnancies in the Foley catheter group was carried out in an outpatient setting, with admittance to labour ward only at start of active labour, the difference would be 4470 versus 3489, respectively (mean difference 981, 95% CI 225-1817). CONCLUSIONS: Oral misoprostol and Foley catheter generate comparable costs. Cervical ripening outside labour ward with a Foley catheter could potentially save almost 1000 per woman. TWEETABLE ABSTRACT: Oral misoprostol or Foley catheter for induction of labour generates comparable costs.

OBJECTIVE: To assess the cost-effectiveness of a cervical pessary to prevent preterm delivery in women with a multiple pregnancy. METHODS: The study design comprised an economic analysis of data from a randomized clinical trial evaluating cervical pessaries (ProTWIN). Women with a multiple pregnancy were included and an economic evaluation was performed from a societal perspective. Costs were estimated between the time of randomization and 6 weeks postpartum. The prespecified subgroup of women with a cervical length (CL) < 25(th) centile (< 38 mm) was analyzed separately. The primary endpoint was poor perinatal outcome occurring up to 6 weeks postpartum. Direct medical costs and health outcomes were estimated and incremental cost-effectiveness ratios for costs to prevent one poor outcome were calculated. RESULTS: Mean costs in the pessary group (n = 401) were 21,783 vs 21,877 in the group in which no pessary was used (n = 407) (difference, - 94; 95% CI, - 5975 to 5609). In the prespecified subgroup of women with a CL < 38 mm we demonstrated a significant reduction in poor perinatal outcome (12% vs 29%; RR, 0.40; 95% CI, 0.19-0.83). Mean costs in the pessary group (n = 78) were 25,141 vs 30,577 in the no-pessary group (n = 55) (difference, - 5436 (95% CI, - 11,001 to 1456). In women with a CL < 38 mm, pessary treatment was the dominant strategy (more effective and less costly) with a probability of 94%. CONCLUSION: Cervical pessaries in women with a multiple pregnancy involve costs comparable to those in women without pessary treatment. However, in women with a CL < 38 mm, treatment with a cervical pessary appears to be highly cost-effective.

OBJECTIVE: To externally validate two models from the USA (entry-to-care [ETC] and close-to-delivery [CTD]) that predict successful intended vaginal birth after caesarean (VBAC) for the Dutch population. DESIGN: A nationwide registration-based cohort study. SETTING: Seventeen hospitals in the Netherlands. POPULATION: Seven hundred and sixty-three pregnant women, each with one previous caesarean section and a viable singleton cephalic pregnancy without a contraindication for an intended VBAC. METHODS: The ETC model comprises the variables maternal age, prepregnancy body mass index (BMI), ethnicity, previous vaginal delivery, previous VBAC and previous nonprogressive labour. The CTD model replaces prepregnancy BMI with third-trimester BMI and adds estimated gestational age at delivery, hypertensive disease of pregnancy, cervical examination and induction of labour. We included consecutive medical records of eligible women who delivered in 2010. For validation, individual probabilities of women who had an intended VBAC were calculated. MAIN OUTCOME MEASURES: Discriminative performance was assessed with the area under the curve (AUC) of the receiver operating characteristic and predictive performance was assessed with calibration plots and the Hosmer-Lemeshow (H-L) statistic. RESULTS: Five hundred and fifteen (67%) of the 763 women had an intended VBAC; 72% of these (371) had an actual VBAC. The AUCs of the ETC and CTD models were 68% (95% CI 63-72%) and 72% (95% CI 67-76%), respectively. The H-L statistic showed a P-value of 0.167 for the ETC model and P = 0.356 for the CTD model, indicating no lack of fit. CONCLUSION: External validation of two predictive models developed in the USA revealed an adequate performance within the Dutch population.

OBJECTIVE: To develop and internally validate a model that predicts the outcome of an intended vaginal birth after caesarean (VBAC) for a Western European population that can be used to personalise counselling for deliveries at term. DESIGN: Registration-based retrospective cohort study. SETTING: Five university teaching hospitals, seven non-university teaching hospitals, and five non-university non-teaching hospitals in the Netherlands. POPULATION: A cohort of 515 women with a history of one caesarean section and a viable singleton pregnancy, without a contraindication for intended VBAC, who delivered at term. METHODS: Potential predictors for a vaginal delivery after caesarean section were chosen based on literature and expert opinions. We internally validated the prediction model using bootstrapping techniques. MAIN OUTCOME MEASURES: Predictors for VBAC. For model validation, the area under the receiver operating characteristic curve (AUC) for discriminative capacity and calibration-per-risk-quantile for accuracy were calculated. RESULTS: A total of 371 out of 515 women had a VBAC (72%). Variables included in the model were: estimated fetal weight greater than the 90(th) percentile in the third trimester; previous non-progressive labour; previous vaginal delivery; induction of labour; pre-pregnancy body mass index; and ethnicity. The AUC was 71% (95% confidence interval, 95% CI = 69-73%), indicating a good discriminative ability. The calibration plot shows that the predicted probabilities are well calibrated, especially from 65% up, which accounts for 77% of the total study population. CONCLUSION: We developed an appropriate Western European population-based prediction model that is aimed to personalise counselling for term deliveries.

OBJECTIVES: Previous studies on singleton pregnancies have indicated that progestogens may reduce the rate of cervical shortening during pregnancy. The aim of this study was to investigate whether treatment with 17-alpha hydroxyprogesterone caproate (17-OHPC) has an effect on cervical shortening in twin pregnancies. METHODS: This was a secondary analysis of patients who had participated in a multicenter randomized clinical trial on the effectiveness of 17-OHPC in preventing preterm birth in multiple pregnancies (the AMPHIA-trial). We included all trial participants with a twin gestation who had undergone repeat cervical length measurements during pregnancy. We performed a separate analysis of women with repeat measurements in centers where this was standard protocol for multiple pregnancies. The rate of cervical shortening for both the 17-OHPC group and the placebo group was analyzed using a linear mixed model. RESULTS: Of the 671 patients who participated in the trial, 282 (42%) had a twin pregnancy and underwent two or more cervical length measurements. Of these women, 140 were monitored in centers where repeat measurements were standard protocol. We observed an overall reduction of cervical length from 44.3 mm at 14-18 weeks to 30.0 mm at 30-34 weeks' gestation. In the 17-OHPC group, cervical length decreased by 1.04 mm each gestational week, while this was 1.11 mm per week for the placebo group (P = 0.6). For the overall group, each 10% decrease in cervical length led to an increase in the risk of preterm birth (hazard ratio, 1.14; 95% CI, 1.08-1.21). CONCLUSION: In women with a twin pregnancy, there is progressive shortening of the cervix during pregnancy, regardless of 17-OHPC use.

Women on Web is a service that uses telemedicine to help women access mifepristone and misoprostol in countries with no safe care for termination of pregnancy (TOP). This study reviews the telemedicine service. After an online consultation, women with an unwanted pregnancy of up to 9 weeks are referred to a doctor. If there are no contraindications, a medical TOP is conducted by mail. After maximising the follow up from 54.8 to 77.6%, 12.6% decided not to do the TOP and 6.8% of the women who did the medical TOP at home needed a vacuum aspiration. Telemedicine can provide an alternative to unsafe TOP. Outcomes of care are in the same range as TOP provided in outpatient settings.

Unsafe abortion is a major public health concern in many developing countries, contributing to a substantial proportion of maternal deaths. Increased legal access to abortion services is associated with improvement in mortality and morbidity. Safe illegal abortion by means of drugs is another possible way to prevent this unnecessary harm to women. The Dutch government, however, is now proposing legal changes that will diminish the access to medical abortion by general practitioners.

A majority of Dutch women present their request for termination of pregnancy very early after their missed period. For these women, medical abortion with mifepriston and misoprostol is a good option. The method is only rarely used in The Netherlands. A change in attitude of the care-providers, dissemination of information to women and new legislation is needed to increase the use of this non-invasive treatment, which has proven to be safe up to 9 weeks in the home situation.

Medically unexplained (gynecological) symptoms can be viewed as an indication of the somatization of negative emotions. Most studies regarding psychological correlates of medically unexplained gynecological symptoms have paid attention only to certain personality characteristics of women with these symptoms. In this study the reporting of physical symptoms and the resulting illness behavior is explained in terms of information processing or a perception process, i.e. the process by which people detect and interpret physical sensations as symptoms of illness (symptom perception). Symptom perception is in part determined by environmental characteristics and cognitive and emotional processes, such as variation in daily life, (coping with) emotional threat and the use of cognitive illness schemes. Differences in symptom perception and illness behavior of women with medically unexplained and explained gynecological symptoms, compared to women with medically explained gynecological symptoms and a control group, were established with the help of a questionnaire, containing a number of scales. As expected, women with medically unexplained gynecological symptoms had higher reports of common symptoms and sensations and showed also more other illness behavior than the other two groups. They reported less variation and more threat in daily life than the other two groups. These variables together with the use of illness schemes contributed most to symptom reporting of women with medically unexplained symptoms. It is concluded that defence against threat is probably an important determinant. Suggestions for further research and some practical implications are discussed.

In a multicenter randomized controlled trial involving 220 women with retained placenta no beneficial effects could be established of intraumbilical vein administration of 10 IU of oxytocin in 20 ml of saline solution. A reduction was not gained in the rate of manual removal of the placenta and there was no decrease in the amount of blood loss. Oxytocin only induced a minor shortening of the median time interval from administration to the spontaneous expulsion of the placenta as compared with a placebo injection. Maternal serum alpha-fetoprotein levels before and after intraumbilical vein injection did not show evidence of fetomaternal transfusion.

Preferred and actual locations of confinement were compared in a group of 170 nulliparous women. Voluntary changes in preferred location for birth were rare and concerned only changes from hospital to home confinement. Obligatory changes due to referral to consultant obstetricians occurred frequently: 58.8% of the total sample. Fewer referrals were found for women with an initial preference for a home confinement (53%) than for those who preferred a hospital confinement (64%). Most referrals occurred in the group of older women initially in doubt about their preferred location for giving birth: 72%. The differences were not significant, however. To reveal differences between referrals and non-referrals, discriminant analysis was performed at the 18th week of gestation. The explained variance for the total group of referrals was 64.7%. Partially, the variables pertaining to the explained variance were the same as those related to a preferred hospital confinement. The explained variance for the group of referrals in which psychosocial influences were presupposed was not better, with the exception of referrals due to insufficient progress during labour: 76.4% of the variance could be explained at the 34th gestational week. When birth weight and amenorrhoea were included, these percentages increased to 79.0 and 84.8%, respectively.
