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.

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.
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.

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.
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.
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.
Objective
To investigate whether a history of spontaneous preterm birth (SPTB) predisposes to maternal hypertension.
Design
Retrospective case–control study.
Setting
Two affiliated university medical ...hospitals in Amsterdam, the Netherlands.
Population
We included 350 women with a history of SPTB between 22 and 36+6 weeks and 166 women with a history of a term birth. Women with pregnancy complications that are known to be associated with cardiovascular disease were excluded.
Methods
Both groups underwent cardiovascular risk assessment 9–16 years after pregnancy. We performed a subgroup analysis based upon the severity of SPTB.
Main Outcome Measures
Hypertension. Secondary outcomes – metabolic syndrome, mean blood pressure, anthropometrics, blood and urine sampling, Framingham Risk Score and Systematic Coronary Risk Evaluation.
Results
A history of SPTB was significantly associated with hypertension; adjusted odds ratio 1.60 (95% confidence interval 1.04–2.46, p = 0.033). Abdominal obesity was more often diagnosed after SPTB (n = 163, 46.6% versus n = 54, 32.5%, p = 0.003) and was more pronounced with more severe preterm birth (p = 0.002).
Conclusions
The presence of hypertension 9–16 years after pregnancy was statistically significantly higher among women with a history of SPTB than among women with a history of uncomplicated term birth. Women with a history of SPTB were more often diagnosed with abdominal obesity, especially those with a history of extreme preterm birth.
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 Background Women with hypertensive disorders in pregnancy, in particular early-onset preeclampsia, are at increased risk of developing cardiovascular disease later in life. These women have ...a more than two-fold increased risk to die from cardiovascular diseases. Most studies focused on identification of risk factors shortly after pregnancy. Less is known on the prevalence of risk factors or actual signs of cardiovascular disease 5 – 20 years later. The presence of hypertension or metabolic syndrome can be seen as an opportunity for preventive interventions to reduce the development of severe cardiovascular diseases like myocardial infarction and stroke. Objective To assess cardiovascular risk factors and established cardiovascular disease in women after early-onset preeclampsia, in the fifth decade of life. As a consequence we can assess if there is still a window of opportunity for preventive measures and to establish in what proportion of women cardiovascular disease has already developed. Study Design In a prospective observational study cardiovascular risk assessment was performed in women with early-onset preeclampsia (<34 weeks gestation) and normotensive controls (≥37 weeks gestation) 9-16 years after their index pregnancy. Medical records of two tertiary hospitals in Amsterdam, The Netherlands, were consecutively screened and all eligible women were invited. Cardiovascular risk assessment consisted of a questionnaire, blood pressure measurement, anthropometrics, blood and urine for fasting lipids, lipoproteins, glucose levels, HbA1c, renal function, NT-proBNP and albuminuria. Past history of cardiovascular diseases (i.e. myocardial infarction and stroke) was determined. Prevalence of women presenting in an optimal window of opportunity for preventive measures was defined by presence of cardiovascular risk factors (i.e. hypertension and metabolic syndrome) but in the absence of established cardiovascular diseases (i.e. myocardial infarction and stroke). Results Women with a history of early-onset preeclampsia (n=131) had significantly higher systolic- and diastolic blood pressure, higher body mass index, had more often an abnormal lipid profile (lower HDL levels, higher triglycerides), higher HbA1c and higher levels of albuminuria compared to controls (n=56). None of the women with a history of early-onset preeclampsia was diagnosed with cardiovascular disease; 38.2% were diagnosed with hypertension; 18.2% were diagnosed with metabolic syndrome. A total of 42% met the criteria for the window of opportunity for preventive measures. In women with a history of an uncomplicated pregnancy, no women were diagnosed with cardiovascular disease; 14.3% were diagnosed with hypertension; 1.8% with metabolic syndrome. In this cohort 14.3% met the criteria for the window of opportunity for preventive measures. Conclusion A large proportion of women who experienced early-onset preeclampsia had major cardiovascular risk factors in the fifth decade of life, compared to healthy controls. These women are currently outside the scope of most preventive programs due to their relatively young age, but have important modifiable risk factors for cardiovascular diseases.
