Awareness is growing that cancer can be treated during pregnancy, but the effect of this change on maternal and neonatal outcomes is unknown. The International Network on Cancer, Infertility and ...Pregnancy (INCIP) registers the incidence and maternal, obstetric, oncological, and neonatal outcomes of cancer occurring during pregnancy. We aimed to describe the oncological management and obstetric and neonatal outcomes of patients registered in INCIP and treated in the past 20 years, and assess associations between cancer type or treatment modality and obstetric and neonatal outcomes.
This descriptive cohort study included pregnant patients with cancer registered from all 37 centres (from 16 countries) participating in the INCIP registry. Oncological, obstetric, and neonatal outcome data of consecutive patients diagnosed with primary invasive cancer during pregnancy between Jan 1, 1996, and Nov 1, 2016, were retrospectively and prospectively collected. We analysed changes over time in categorical patient characteristics, outcomes, and treatment methods with log-binomial regression. We used multiple logistic regression to analyse preterm, prelabour rupture of membranes (PPROM) or preterm contractions, small for gestational age, and admission to the neonatal intensive care unit (NICU). The INCIP registry study is registered with ClinicalTrials.gov, number NCT00330447, and is ongoing.
1170 patients were included in the analysis and 779 (67%) received treatment during pregnancy. Breast cancer was the most common malignant disease (462 39%). Every 5 years, the likelihood of receiving treatment during pregnancy increased (relative risk RR 1·10, 95% CI 1·05–1·15), mainly related to an increase of chemotherapeutic treatment (1·31, 1·20–1·43). Overall, 955 (88%) of 1089 singleton pregnancies ended in a livebirth, of which 430 (48%) of 887 pregnancies ended preterm. Each 5 years, we observed more livebirths (RR 1·04, 95% CI 1·01–1·06) and fewer iatrogenic preterm deliveries (0·91, 0·84–0·98). Our data suggest a relationship between platinum-based chemotherapy and small for gestational age (odds ratio OR 3·12, 95% CI 1·45–6·70), and between taxane chemotherapy and NICU admission (OR 2·37, 95% CI 1·31–4·28). NICU admission seemed to depend on cancer type, with gastrointestinal cancers having highest risk (OR 7·13, 95% CI 2·86–17·7) and thyroid cancers having lowest risk (0·14, 0·02–0·90) when compared with breast cancer. Unexpectedly, the data suggested that abdominal or cervical surgery was associated with a reduced likelihood of NICU admission (OR 0·30, 95% CI 0·17–0·55). Other associations between treatment or cancer type and outcomes were less clear.
Over the years, the proportion of patients with cancer during pregnancy who received antenatal treatment increased, especially treatment with chemotherapy. Our data indicate that babies exposed to antenatal chemotherapy might be more likely to develop complications, specifically small for gestational age and NICU admission, than babies not exposed. We therefore recommend involving hospitals with obstetric high-care units in the management of these patients.

Summary Pre-eclampsia affects 3–5% of pregnancies and is traditionally diagnosed by the combined presentation of high blood pressure and proteinuria. New definitions also include maternal organ ...dysfunction, such as renal insufficiency, liver involvement, neurological or haematological complications, uteroplacental dysfunction, or fetal growth restriction. When left untreated, pre-eclampsia can be lethal, and in low-resource settings, this disorder is one of the main causes of maternal and child mortality. In the absence of curative treatment, the management of pre-eclampsia involves stabilisation of the mother and fetus, followed by delivery at an optimal time. Although algorithms to predict pre-eclampsia are promising, they have yet to become validated. Simple preventive measures, such as low-dose aspirin, calcium, and diet and lifestyle interventions, show potential but small benefit. Because pre-eclampsia predisposes mothers to cardiovascular disease later in life, pregnancy is also a window for future health. A collaborative approach to discovery and assessment of the available treatments will hasten our understanding of pre-eclampsia and is an effort much needed by the women and babies affected by its complications.
Fibroids have been identified as a possible risk factor for preterm birth, however, the magnitude of this risk is unclear. Our objective was to determine the risk of total, spontaneous, and medically ...indicated preterm birth in women with fibroids.
A literature search was performed on 9 June 2021. We selected studies reporting on preterm birth in women with and without fibroids. Fibroids had to be diagnosed by routine ultrasound before or during pregnancy. Main outcomes were total preterm birth <37, <34, <32, and <28 weeks of gestation, and spontaneous and medically indicated preterm birth. Two authors independently performed study selection, data extraction and quality assessment. We performed quality assessment with the Newcastle-Ottawa scale. Meta-analyses were presented as Odds Ratios (ORs) with 95% Confidence Intervals (95%CIs).
The search yielded 2078 unique articles of which 11 were included. Meta-analysis for preterm birth <37 weeks of gestation included 256,650 singleton deliveries: 12,309 with fibroids and 244,341 without fibroids. Women with fibroids had a higher rate of preterm birth (11.6% versus 9.0%; OR 1.66, 95%CI 1.29-2.14). Fibroids were also associated with preterm birth <34 (OR 1.88, 95%CI 1.34-2.65), <32 (OR 2.03, 95%CI 1.40-2.95) and <28 (OR 2.24, 95%CI 1.45-3.47) weeks of gestation. Data on type of preterm birth was limited: one study showed a significant association of fibroids with spontaneous preterm birth and another with indicated preterm birth. The main limitations of the included studies were the lack of correction for confounders, the risk of ascertainment bias due to possible underreporting of fibroids, and the substantial heterogeneity between studies.
Our results suggest fibroids are associated with an increased risk of preterm birth, with a stronger risk at earlier gestational ages. We encourage further research to clarify the association between fibroids and preterm birth by systematic myometrial assessment in pregnancy.

Systemic inflammation, endothelial dysfunction and deficient vascularization of either uterus or myocardium are mechanistic hallmarks of early-onset preeclampsia and heart failure with preserved ...ejection fraction (HFpEF). HFpEF is especially prevalent in elderly women and preceded in middle age by preclinical left ventricular (LV) diastolic dysfunction. To detect if preeclampsia predisposes to HFpEF at later age, echocardiographic indices of LV function and of LV structure and biomarkers of systemic inflammation and of endothelial dysfunction were compared in middle-aged women with a history of early-onset preeclampsia or uncomplicated pregnancy.
Middle-aged women with a history of early-onset preeclampsia (n = 131) or uncomplicated pregnancy (n = 56) were prospectively recruited 9 to 16 years after pregnancy. Women with a history of preeclampsia had higher body mass index (p = 0.006), blood pressure (p<0.001) and plasma levels of interleukin-6 (p = 0.005) and soluble intercellular adhesion molecule-1 (sICAM-1) (p = 0.014). They had thicker septal (p = 0.001) and posterior (p = 0.003) LV walls and worse diastolic LV function evident from reduced mean mitral annular lengthening velocity (E'mean; p = 0.007) and higher ratio of early diastolic mitral flow velocity (E) over E'mean (E/E'mean; p<0.001). Differences of sICAM-1, E'mean and E/E'mean remained significant after accounting for BMI and blood pressure.
History of preeclampsia predisposes in middle age to worse LV diastolic function, which could increase the likelihood of later HFpEF development. This predisposition derives not only from persistent cardiovascular risk but may also be caused by persistent endothelial dysfunction hindering adequate vascularization in the uterus during pregnancy and in the myocardium in middle age.

Spontaneous preterm birth (SPTB) is a major cause of neonatal morbidity and mortality worldwide and defining its risk factors is necessary to reduce its prevalence. Recent studies have pointed out ...that bacterial vaginosis, a disturbance in the vaginal microbiome, is associated with SPTB. It is hypothesized that vaginal hygiene practices can alter the vaginal microbiome and are therefore associated with SPTB, but there are no studies investigating this matter. A case-control study was conducted between August 2018 and July 2021 in two affiliated university medical centers in Amsterdam, the Netherlands. We included a total of 79 women with a SPTB and compared them with 156 women with a term birth. Women with uterine anomalies, a history of cervical surgery or major congenital anomalies of the fetus were excluded. All participants filled in a questionnaire about vaginal washing with water, soap or gel, the use of intravaginal douches and vaginal steaming, both before and during pregnancy. Most women washed vaginally with water, 144 (61.3%) women before pregnancy and 135 (57.4%) women during pregnancy. A total of 43 (18.3%) washed with soap before and 36 (15.3%) during pregnancy. Before pregnancy, 40 (17.0%) women washed with vaginal gel and 27 (11.5%) during pregnancy. We found that the use of vaginal gel before pregnancy (aOR 2.29, 95% CI: 1.08-4.84) and even more during pregnancy, was associated with SPTB (aOR 3.45, 95% CI: 1.37-8.67). No association was found between washing with water or soap, intravaginal douching, or vaginal steaming and SPTB. Our findings suggest that the use of vaginal gel is associated with SPTB. Women should be informed that vaginal use of gels might not be safe.

Introduction
The incidence of induction of labor, for both medical reasons and as an elective procedure, has been rising and a further increase in induction of labor following the ARRIVE trial may be ...expected. The effects of induction of labor at term on childhood neurodevelopment, however, are not well studied. We aimed to study the influence of elective induction of labor for each week of gestation separately from 37 to 42 weeks on offspring school performance at 12 years of age after uncomplicated pregnancies.
Material and methods
We performed a population‐based study among 226 684 liveborn children from uncomplicated singleton pregnancies, born from 37+0 to 42+0 weeks of gestation in cephalic presentation in 2003–2008 (no hypertensive disorders, diabetes or birthweight ≤p5) in the Netherlands. Children with congenital anomalies, of non‐white mothers and born after planned cesarean section were excluded. Birth records were linked with national data on school achievement. We compared, using a fetus‐at‐risk approach and per week of gestation, school performance score and secondary school level at age 12 in those born after induction of labor to those born after non‐intervention, ie spontaneous onset of labor in the same week plus all those born at later gestations. Education scores were standardized to a mean of 0 and a standard deviation of 1 and adjusted in the regression analyses.
Results
For each gestational age up to 41 weeks, induction of labor was associated with decreased school performance scores compared with non‐intervention (at 37 weeks −0.05 SD, 95% confidence interval CI −0.10 to −0.01 SD; adjusted for confounding factors). After induction of labor, fewer children reached higher secondary school level (at 38 weeks 48% vs 54%; adjusted odds ratio aOR 0.88, 95% CI 0.82–0.94).
Conclusions
In women with uncomplicated pregnancies at term, consistently, at every week of gestation from 37 to 41 weeks, induction of labor is associated with lower offspring school performance at age 12 and lower secondary school level compared with non‐intervention, although residual confounding may remain. These long‐term effects of induction of labor should be incorporated in counseling and decision making.
Induction of labor at term is associated with reduced offspring school performance compared with non‐intervention in uncomplicated pregnancies at every week from 37 to 41 weeks. Children are 10% less likely to reach higher secondary school level following elective induction.
Abstract Preeclampsia is a common pregnancy specific disease, that presents with hypertension and a variety of organ failures, including malfunction of kidneys, liver and lungs. At present, the only ...definitive treatment of preeclampsia is end the pregnancy and deliver the neonate and placenta. For women with mild preeclampsia in the preterm phase of pregnancy, expectant management is generally indicated to improve fetal maturity, often requiring maternal medical treatment. Last decades, more evidence is available that the underlying mechanism of preeclampsia, endothelial disease, is not limited to pregnancy but increases cardiovascular risk in later life. In this review, we present the most recent insight in preeclampsia with focus on impact on the fetus, short and long-term outcome of offspring's, and long-term outcome of women with a history of preeclampsia.
Cancer during pregnancy is relatively rare but may lead to maternal mortality. We aimed to assess the incidence of cancer related maternal mortality and the neonatal outcome in these patients. Also, ...doctor- and patient-related delay in cancer diagnosis and therapy among patients with cancer related maternal mortality is assessed.
Maternal mortality was defined as death during pregnancy or within 1 year after delivery. Data of the Dutch Maternal Mortality Committee was used to calculate the cancer related maternal mortality rate and to assess neonatal outcome in the Netherlands. Delay was scored by ten medical specialist based on case descriptions.
Cancer related maternal mortality rate was 1.23 per 100,000 live births. Delay in either diagnosis or treatment occurred in 65%. Delay in diagnosis was more frequent then delay in treatment, and was mainly caused by health care providers. Only 77% of pregnancies were ongoing, and 65% ended preterm of which 85% was induced.
Avoiding delay in diagnosis and therapy in case of pregnancy related cancer could potentially improve maternal and neonatal outcome. It is therefore essential to increase awareness among health care providers about the occurrence and recurrence of cancer in pregnancy and the possibilities of diagnostic and therapeutic interventions in these women.
Introduction
The associations of epidural analgesia and low Apgar score found in the Swedish Registry might be a result of confounding by indication. The objective of this study was to assess the ...possible effect of intrapartum epidural analgesia on low Apgar score and neonatal intensive care unit (NICU) admission in term born singletons with propensity score matching.
Material and methods
This was a propensity score matched study (n = 257 872) conducted in a national cohort of 715 449 term live born singletons without congenital anomalies in the Netherlands. Mothers with prelabor cesarean section were excluded. Main outcome measures were 5‐minute Apgar score <7, 5‐minute Apgar score <4 and admission to a NICU for at least 24 hours. First, an analysis of the underlying risk factors for low Apgar score <7 was performed. Multivariable analyses were applied to assess the effect of the main risk factor, intrapartum epidural analgesia, on low Apgar score to adjust the results for confounding factors. Second, a propensity score matched analysis on the main risk factors for epidural analgesia was applied. By propensity score matching the (confounding) characteristics of the women who received epidural analgesia with the characteristics of the control women without epidural analgesia, the effect of possible confounding by indication is minimized.
Results
Intrapartum epidural analgesia was performed in 128 936 women (18%). Apgar score <7 was present in 1.0%, Apgar score <4 in .2% and NICU admission in .4% of the deliveries. The strongest risk factor for Apgar score <7 was epidural analgesia (adjusted odds ratio aOR 1.9, 95% confidence interval CI 1.8‐2.0). The propensity score matched adjusted analysis of women with epidural analgesia showed significant adverse neonatal outcomes: aOR 1.8 (95% CI 1.7‐1.9) for AS <7, aOR 1.6 (95% CI 1.4‐1.9) for AS <4 and aOR 1.7 (95% CI 1.6‐1.9) for NICU admission. The results of epidural analgesia on AS <7 were also significantly increased for spontaneous start of labor (aOR 2.0, 95% CI 1.8‐2.1) and for spontaneous delivery.
Conclusions
Intrapartum epidural analgesia at term is strongly associated with low Apgar score and more NICU admissions, especially in spontaneous deliveries. This association needs further research and awareness.
Introduction
Fear of childbirth is a well‐known problem during pregnancy and can have implications for childbirth, including prolonged labor, use of epidural analgesia, obstetric complications, ...presence of traumatic stress symptoms, or request for an elective cesarean section. The coronavirus disease 2019 (COVID‐19) pandemic has affected mental health and therefore could have increased fear of childbirth during the pandemic. The aim of this study was to investigate fear of childbirth during the pandemic in the Netherlands compared with a reference group from before the pandemic.
Material and methods
We conducted a cross‐sectional study to evaluate pregnant women during the first and second waves of COVID‐19 compared with both each other and with pregnant women from before the pandemic. Participants were recruited through social media platforms, hospitals, and midwifery practices. Pregnant women aged ≥18 years who had mastered the Dutch language were eligible to participate. Fear of childbirth was measured with the Wijma Delivery Expectancy Questionnaire online using a cut‐off score of ≥85 to indicate clinically relevant fear of childbirth. The primary outcome was the prevalence of fear of childbirth. We undertook additional analyses to specifically look at possible effect modification.
Results
In total, 1102 pregnant women completed the questionnaire during the first wave of the pandemic, 731 during the second wave, and 364 before the pandemic. Fear of childbirth was present in 10.6%, 11.4%, and 18.4%, respectively. We considered possible effect modification, which indicated that age and parity had a significant influence. In participants during the first wave of COVID‐19, nulliparous women had significantly lower odds (odds ratio OR 0.50; 95% confidence interval CI 0.34–0.73; p < 0.01) of having a fear of childbirth than did the reference group. Both younger participants in the first wave (OR 0.59; 95% CI 0.37–0.93; p < 0.05) and older participants in the first wave (OR 0.44; 95% CI 0.28–0.71; p < 0.01) and the second wave (OR 0.36; 95% CI 0.21–0.62; p < 0.01) of COVID‐19 had lower odds of fear of childbirth than the reference group.
Conclusions
Pregnant women during the first and second waves of COVID‐19 had lower fear of childbirth scores than pregnant women before the pandemic, indicating less fear of childbirth during the pandemic. This could be explained by an increased level of information, more time to consume information, and better work–life balance with more people working at home during the pandemic.
