Objective
To investigate whether vaginal Group B Streptococcus (GBS) colonisation or other baseline characteristics of women with preterm premature rupture of membranes (PPROM) can help in ...identifying subgroups of women who would benefit from immediate delivery.
Design
Secondary analysis of the PPROMEXIL trials.
Setting
Sixty hospitals in the Netherlands.
Population
Women with PPROM between 34 and 37 weeks of gestation.
Methods
Random assignment of 723 women to immediate delivery or expectant management.
Main outcome measures
Early onset neonatal sepsis.
Results
Vaginal GBS colonisation status was the only marker which was significantly associated with the benefit of immediate delivery (P for interaction: 0.04). GBS colonisation was observed in 14% of women. The risk of early onset neonatal sepsis in GBS‐positive women was high (15.2%) when they were managed expectantly but this risk was reduced to 1.8% with immediate delivery. The early onset neonatal sepsis risk was much lower in neonates of GBS‐negative women: 2.6% after expectant management and 2.9% with immediate delivery. We estimated that by inducing labour only in GBS‐positive women, there would be a 10.4% increase in term delivery rate, while keeping neonatal sepsis and caesarean delivery rates comparable to a strategy of labour induction for all.
Conclusions
Our post hoc findings suggest that women with PROM between 34 and 37 weeks might benefit from immediate delivery if they have GBS vaginal colonisation, while in GBS‐negative women labour induction could be delayed until 37 weeks.
Objective
To assess the economic consequences of labour induction with Foley catheter compared to prostaglandin E2 gel.
Design
Economic evaluation alongside a randomised controlled trial.
Setting
...Obstetric departments of one university and 11 teaching hospitals in the Netherlands.
Population
Women scheduled for labour induction with a singleton pregnancy in cephalic presentation at term, intact membranes and an unfavourable cervix; and without previous caesarean section.
Methods
Cost‐effectiveness analysis from a hospital perspective.
Main outcome measures
We estimated direct medical costs associated with healthcare utilisation from randomisation to 6 weeks postpartum. For caesarean section rate, and maternal and neonatal morbidity we calculated the incremental cost‐effectiveness ratios, which represent the costs to prevent one of these adverse outcomes.
Results
Mean costs per woman in the Foley catheter group (n = 411) and in the prostaglandin E2 gel group (n = 408), were €3297 versus €3075, respectively, with an average difference of €222 (95% confidence interval −€157 to €633). In the Foley catheter group we observed higher costs due to longer labour ward occupation and less cost related to induction material and neonatal admissions. Foley catheter induction showed a comparable caesarean section rate compared with prostaglandin induction, therefore the incremental cost‐effectiveness ratio was not informative. Foley induction resulted in fewer neonatal admissions (incremental cost‐effectiveness ratio €2708) and asphyxia/postpartum haemorrhage (incremental cost‐effectiveness ratios €5257) compared with prostaglandin induction.
Conclusions
Foley catheter and prostaglandin E2 labour induction generate comparable costs.
Objective
To describe characteristics, risk factors and maternal, obstetric and neonatal outcomes of pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2).
Design
...Multi‐centre prospective population‐based cohort study.
Setting
Nationwide study in the Netherlands.
Population
Pregnant women with confirmed SARS‐CoV‐2 infection admitted to hospital or in home‐isolation: 1 March 2020 to 31 August 2020.
Methods
Pregnant women with positive polymerase chain reaction or antibody tests were registered using the Netherlands Obstetrics Surveillance System (NethOSS). (Selective) testing occurred according to national guidelines. Data from the national birth registry (pregnant pre‐coronavirus disease 2019 COVID‐19 cohort) and an age‐matched cohort of COVID‐19‐positive women (National Institute for Public Health and the Environment; fertile age COVID‐19 cohort) were used as reference.
Main outcome measures
Incidence of SARS‐CoV‐2 infection in pregnant women. Maternal, obstetric and neonatal outcomes including hospital and intensive care admission.
Results
Of 376 registered pregnant women with confirmed SARS‐CoV‐2 infection, 20% (74/376) were admitted to hospital, of whom 84% (62/74) were due to SARS‐CoV‐2; 10% (6/62) were admitted to intensive care and 15% (9/62) to obstetric high‐care units. Risk factors for admission were non‐European country of origin (odds ratio OR 1.73, 95% CI 1.01–2.96) and being overweight/obese (OR 1.86, 95% CI 1.51–3.20). No maternal or perinatal deaths occurred. Caesarean section after labour‐onset was increased (OR 1.58, 95% CI 1.09–2.28). Hospital and intensive care admission were higher compared with the fertile age COVID‐19 cohort (OR 6.75, 95% CI 5.18–8.81 and OR 2.52, 95% CI 1.11–5.77, respectively).
Conclusions
Non‐European country of origin and being overweight/obese are risk factors for severe course of SARS‐CoV‐2 infection in pregnancy, risk of caesarean section and hospital and intensive care unit admission are increased.
Tweetable
Pregnant women with SARS‐CoV‐2 in the Netherlands show increased hospital/ICU admission and caesarean section.
Tweetable
Pregnant women with SARS‐CoV‐2 in the Netherlands show increased hospital/ICU admission and caesarean section.

Objective
To compare incidences, characteristics, management and outcome of eclampsia in the Netherlands and the UK.
Design
A comparative analysis of two population‐based prospective cohort studies.
...Setting
All hospitals with consultant‐led maternity units.
Population
Women with eclampsia in the Netherlands (226) and the UK (264).
Methods
Comparison of individual level data from national studies in the Netherlands and the UK (LEMMoN 2004–06; UKOSS 2005/06).
Main outcome measures
Incidence, maternal complications and differences in management strategies.
Results
Incidences of eclampsia differed significantly between both countries: the Netherlands 5.4/10 000 deliveries versus UK 2.7/10 000 (relative risk RR 1.94, 95% confidence intervals 95% CI 1.6–2.4). The proportion of women with a preceding diagnosis of pre‐eclampsia was comparable between both countries (the Netherlands 42%; UK 43%), as was the proportion who received magnesium sulphate prophylaxis. Women in the Netherlands had a significantly higher maximum diastolic blood pressure (111 mmHg versus 95 mmHg, P < 0.001); significantly fewer received anti‐hypertensive medication (16% versus 71%; RR 0.2, 95% CI 0.1–0.3) and were treated less often with magnesium sulphate after their first fit (95% versus 99%; RR 0.96, 95% CI 0.92–0.99). Maternal death occurred in three cases in the Netherlands compared with zero in the UK.
Conclusions
The incidence of eclampsia in the Netherlands was twice as high compared with the UK when using uniform definitions. Women with eclampsia in the Netherlands were not managed according to guidelines, particularly with respect to blood pressure management. Changes in management practice may reduce both incidence and poor outcomes.
Summary
Congenital platelet disorders (CPDs) are rare bleeding disorders that are associated with mucocutaneous bleeds. However, data on vaginal bleeding in women with CPDs are scarce. A set of ...generic and bleeding‐specific questionnaires were used to evaluate the prevalence of vaginal bleeding, its impact on quality of life (QoL) and sexual functioning and the consequences for pregnancy, miscarriage and delivery in a cohort of women who were referred for diagnostic evaluation for CPDs. A total of 78 women included in the study were either diagnosed with a CPD (n = 35) or were clinically suspected of a CPD (n = 43). Heavy menstrual bleeding (HMB) was reported by a large proportion of women, which mainly started at menarche. In all, 76% of women received any kind of HMB treatment, often leading to surgical prodecures. HMB was shown to have a high impact on QoL, which improved upon treatment. Even though women reported that vaginal bleeding affects sexuality, this topic is not frequently discussed with physicians. Heavy blood loss frequently occurred after miscarriage/delivery, often requiring treatment. Women with (suspected) CPDs frequently encounter HMB, negatively impacting daily life and sexual functioning. Together with peripartum bleeding, these data highlight the burden of vaginal bleeding in CPDs and importance of adequate treatment.
Abstract Objective To assess the safety and effectiveness of a transcervical Foley catheter compared to vaginal prostaglandin E2 inserts for term induction of labour. Study design We conducted an ...open-label randomized controlled trial in five hospitals in the Netherlands. Women with a singleton term pregnancy in cephalic presentation, intact membranes, unfavourable cervix, and no prior caesarean section were enrolled. Participants were randomly allocated by a web-based randomization system to induction of labour with a 30 ml Foley catheter or 10 mg slow-release vaginal prostaglandin E2 inserts in a 1:1 ratio. Due to the nature of the intervention this study was not blinded. The primary outcome was the caesarean section rate. Secondary outcomes were maternal and neonatal morbidity and time from intervention to birth. Additionally, we carried out a systematic review and meta-analysis of similar studies. Results We analyzed 226 women: 107 received a Foley catheter and 119 inserts. Caesarean section rates were comparable (20% versus 22%, RR 0.90, 95% CI 0.54–1.50). Secondary outcomes showed no differences. We observed no serious maternal or neonatal morbidity. Meta-analysis showed comparable caesarean section rates, but significantly fewer cases of hyperstimulation during the ripening phase when a Foley catheter was used. Conclusions We found, in this relatively small study, no differences in effectiveness and safety of induction of labour with a Foley catheter and 10 mg slow release vaginal prostaglandin E2 inserts. Meta-analysis confirmed a comparable caesarean section rate, and showed fewer cases of hyperstimulation when a Foley catheter was used.
•At population level, women with unexplained recurrent miscarriage had less oral sex.•Oral sex seems to influence pregnancy outcome in a proportion of the women.•Oral sex might induce maternal ...tolerance towards paternal antigens of the fetus.
A possible way of immunomodulation of the maternal immune system before pregnancy would be exposure to paternal antigens via seminal fluid to oral mucosa. We hypothesized that women with recurrent miscarriage have had less oral sex compared to women with uneventful pregnancy.
In a matched case control study, 97 women with at least three unexplained consecutive miscarriages prior to the 20th week of gestation with the same partner were included. Cases were younger than 36 years at time of the third miscarriage. The control group included 137 matched women with an uneventful pregnancy. The association between oral sex and recurrent miscarriage was assessed with conditional logistic regression, odds ratios (ORs) were estimated. Missing data were imputed using Imputation by Chained Equations.
In the matched analysis, 41 out of 72 women with recurrent miscarriage had have oral sex, whereas 70 out of 96 matched controls answered positive to this question (56.9% vs. 72.9%, OR 0.50 95%CI 0.25−0.97, p = 0.04). After imputation of missing exposure data (51.7%), the association became weaker (OR 0.67, 95%CI 0.36–1.24, p = 0.21).
In conclusion, this study suggests a possible protective role of oral sex in the occurrence of recurrent miscarriage in a proportion of the cases. Future studies in women with recurrent miscarriage explained by immune abnormalities should reveal whether oral exposure to seminal plasma indeed modifies the maternal immune system, resulting in more live births.
Abstract Background Thyroid peroxidase antibodies (TPO-Ab) in euthyroid women are associated with recurrent miscarriage (RM) and other pregnancy complications such as preterm birth. It is unclear if ...treatment with levothyroxine improves pregnancy outcome. Aim The aim of this study is to determine the effect of levothyroxine administration on live birth rate in euthyroid TPO-Ab positive women with recurrent miscarriage. Methods/design We will perform a multicenter, placebo controlled randomized trial in euthyroid women with recurrent miscarriage and TPO-Ab. Recurrent miscarriage is defined as two or more miscarriages before the 20th week of gestation. The primary outcome is live birth, defined as the birth of a living fetus beyond 24 weeks of gestation. Secondary outcomes are ongoing pregnancy at 12 weeks, miscarriage, preterm birth, (serious) adverse events, time to pregnancy and survival at 28 days of neonatal life. The analysis will be performed according to the intention to treat principle. We need to randomize 240 women (120 per group) to demonstrate an improvement in live birth rate from 55% in the placebo group to 75% in the levothyroxine treatment group. This trial is a registered trial (NTR 3364, March 2012). Here we discuss the rationale and design of the T4-LIFE study, an international multicenter randomized, double blind placebo controlled, clinical trial aimed to assess the effectiveness of levothyroxine in women with recurrent miscarriage and TPO-Ab.

Objective To describe the ...panel audit process and to identify substandard care in selected women from a nationwide prospective cohort study into severe acute maternal morbidity (SAMM) in the Netherlands.
Design Prospective audit of selected women with SAMM.
Setting Eight audit meetings held throughout the Netherlands.
Population All pregnant women in the Netherlands.
Methods Before each meeting, SAMM details of selected women were sent to all panel members for individual assessment by completing an audit form. During a subsequent plenary meeting, findings were discussed and substandard care factors as judged by the majority of assessors were scored.
Main outcome measures Incidence of substandard care and recommendations for improving the quality of care.
Results Substandard care was identified in 53 of 67 women (79%). Specific recommendations were formulated concerning the procedure of audit and concerning local as well as national management guidelines.
Conclusion Our findings reflect SAMM in the Netherlands and substandard care is present in four out of five women. Ongoing audit of women with SAMM is promoted both at local and national level.
