Abstract
Cardiovascular disease (CVD) is globally the leading cause of death and disability. Sex-specific causes of female CVD are under-investigated. Pregnancy remains an underinvestigated sex-specific stress test for future CVD and a hitherto missed opportunity to initiate prevention of CVD at a young age. Population-based studies show a strong association between female CVD and hypertensive disorders of pregnancy. This association is also present after other pregnancy complications that are associated with placental dysfunction, including fetal growth restriction, preterm delivery and gestational diabetes mellitus. Few women are, however, offered systematic cardio-preventive follow-up after such pregnancy complications. These women typically seek help from the health system at first clinical symptom of CVD, which may be decades later. By this time, morbidity is established and years of preventive opportunities have been missed out. Early identification of modifiable risk factors starting postpartum followed by systematic preventive measures could improve maternal cardiovascular health trajectories, promoting healthier societies. In this non-systematic review we briefly summarize the epidemiological associations and pathophysiological hypotheses for the associations. We summarize current clinical follow-up strategies, including some proposed by international and national guidelines as well as user support groups. We address modifiable factors that may be underexploited in the postpartum period, including breastfeeding and blood pressure management. We suggest a way forward and discuss the remaining knowledge gaps and barriers for securing the best evidence-based follow-up, relative to available resources after a hypertensive pregnancy complication in order to prevent or delay onset of premature CVD.

Abstract
The review examines the impact of maternal preeclampsia (PE) on the cardiometabolic and cardiovascular health of offspring. PE, a hypertensive disorder of pregnancy, is responsible for 2 to 8% of pregnancy-related complications. It significantly contributes to adverse outcomes for their infants, affecting the time of birth, the birth weight, and cardiometabolic risk factors such as blood pressure, body mass index (BMI), abdominal obesity, lipid profiles, glucose, and insulin. Exposure to PE in utero predisposes offspring to an increased risk of cardiometabolic diseases (CMD) and cardiovascular diseases (CVD) through mechanisms that are not fully understood. The incidence of CMD and CVD is constantly increasing, whereas CVD is the main cause of morbidity and mortality globally. A complex interplay of genes, environment, and developmental programming is a plausible explanation for the development of endothelial dysfunction, which leads to atherosclerosis and CVD. The underlying molecular mechanisms are angiogenic imbalance, inflammation, alterations in the renin-angiotensin-aldosterone system (RAAS), endothelium-derived components, serotonin dysregulation, oxidative stress, and activation of both the hypothalamic-pituitary-adrenal axis and hypothalamic-pituitary-gonadal axis. Moreover, the potential role of epigenetic factors, such as DNA methylation and microRNAs as mediators of these effects is emphasized, suggesting avenues for future research and therapeutic interventions.

Impact of hypertensive disorders of pregnancy and gestational diabetes mellitus on offspring cardiovascular health in early adolescence. Am J Obstet Gynecol 2024:S0002-9378(24)00563-5. [PMID: 38703941 DOI: 10.1016/j.ajog.2024.04.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 04/24/2024] [Accepted: 04/26/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND Adverse pregnancy outcomes, including hypertensive disorders of pregnancy and gestational diabetes mellitus, influence maternal cardiovascular health long after pregnancy, but their relationship to offspring cardiovascular health following in-utero exposure remains uncertain. OBJECTIVE To examine associations of hypertensive disorders of pregnancy or gestational diabetes mellitus with offspring cardiovascular health in early adolescence. STUDY DESIGN This analysis used data from the prospective Hyperglycemia and Adverse Pregnancy Outcome Study from 2000 to 2006 and the Hyperglycemia and Adverse Pregnancy Outcome Follow-Up Study from 2013 to 2016. This analysis included 3317 mother-child dyads from 10 field centers, comprising 70.8% of Hyperglycemia and Adverse Pregnancy Outcome Follow-Up Study participants. Those with pregestational diabetes and chronic hypertension were excluded. The exposures included having any hypertensive disorders of pregnancy or gestational diabetes mellitus vs not having hypertensive disorders of pregnancy or gestational diabetes mellitus, respectively (reference). The outcome was offspring cardiovascular health when aged 10-14 years, on the basis of 4 metrics: body mass index, blood pressure, total cholesterol level, and glucose level. Each metric was categorized as ideal, intermediate, or poor using a framework provided by the American Heart Association. The primary outcome was defined as having at least 1 cardiovascular health metric that was nonideal vs all ideal (reference), and the second outcome was the number of nonideal cardiovascular health metrics (ie, at least 1 intermediate metric, 1 poor metric, or at least 2 poor metrics vs all ideal [reference]). Modified poisson regression with robust error variance was used and adjusted for covariates at pregnancy enrollment, including field center, parity, age, gestational age, alcohol or tobacco use, child's assigned sex at birth, and child's age at follow-up. RESULTS Among 3317 maternal-child dyads, the median (interquartile) ages were 30.4 (25.6-33.9) years for pregnant individuals and 11.6 (10.9-12.3) years for children. During pregnancy, 10.4% of individuals developed hypertensive disorders of pregnancy, and 14.6% developed gestational diabetes mellitus. At follow-up, 55.5% of offspring had at least 1 nonideal cardiovascular health metric. In adjusted models, having hypertensive disorders of pregnancy (adjusted risk ratio, 1.14 [95% confidence interval, 1.04-1.25]) or having gestational diabetes mellitus (adjusted risk ratio, 1.10 [95% confidence interval, 1.02-1.19]) was associated with a greater risk that offspring developed less-than-ideal cardiovascular health when aged 10-14 years. The above associations strengthened in magnitude as the severity of adverse cardiovascular health metrics increased (ie, with the outcome measured as ≥1 intermediate, 1 poor, and ≥2 poor adverse metrics), albeit the only statistically significant association was with the "1-poor-metric" exposure. CONCLUSION In this multinational prospective cohort, pregnant individuals who experienced either hypertensive disorders of pregnancy or gestational diabetes mellitus were at significantly increased risk of having offspring with worse cardiovascular health in early adolescence. Reducing adverse pregnancy outcomes and increasing surveillance with targeted interventions after an adverse pregnancy outcome should be studied as potential avenues to enhance long-term cardiovascular health in the offspring exposed in utero.

Abstract
OBJECTIVES This study aimed to investigate the genetic association between MTHFR (A1298C) SNP and preeclampsia (PE) in Punjab, Pakistan. METHODS A sample of 80 pregnant women (40 healthy pregnant women and 40 with PE) was pooled for genotyping MTHFR A1298C polymorphism by using the tetra-primer amplification refractory mutation system (ARMS) PCR. The Genotypic and allelic assessments were performed using various statistical techniques. RESULTS The AC genotype and C allele of MTHFR A1298C were found to be associated with decreased risk of PE (odds ratio [OR]: 0.31, risk ratio [RR]: 0.58, p = 0.01), and (odds ratio [OR]: 0.49, risk ratio [RR]: 0.61, p = 0.04), respectively. CONCLUSION In conclusion, genetic polymorphism A1298C in MTHFR may pose a protective effect in the studied population.

Cord blood DNA methylation signatures associated with preeclampsia are enriched for cardiovascular pathways: insights from the VDAART trial. EBioMedicine 2023; 98:104890. [PMID: 37995466 PMCID: PMC10709000 DOI: 10.1016/j.ebiom.2023.104890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 11/07/2023] [Accepted: 11/14/2023] [Indexed: 11/25/2023] Open
Abstract
BACKGROUND Preeclampsia has been associated with maternal epigenetic changes, in particular DNA methylation changes in the placenta. It has been suggested that preeclampsia could also cause DNA methylation changes in the neonate. We examined DNA methylation in relation to gene expression in the cord blood of offspring born to mothers with preeclampsia. METHODS This study included 128 mother-child pairs who participated in the Vitamin D Antenatal Asthma Reduction Trial (VDAART), where assessment of preeclampsia served as secondary outcome. We performed an epigenome-wide association study of preeclampsia and cord blood DNA methylation (Illumina 450 K chip). We then examined gene expression of the same subjects for validation and replicated the gene signatures in independent DNA methylation datasets. Lastly, we applied functional enrichment and network analyses to identify biological pathways that could potentially be involved in preeclampsia. FINDINGS In the cord blood samples (n = 128), 263 CpGs were differentially methylated (FDR <0.10) in preeclampsia (n = 16), of which 217 were annotated. Top pathways in the functional enrichment analysis included apelin signaling pathway and other endothelial and cardiovascular pathways. Of the 217 genes, 13 showed differential expression (p's < 0.001) in preeclampsia and 11 had been previously related to preeclampsia (p's < 0.0001). These genes were linked to apelin, cGMP and Notch signaling pathways, all having a role in angiogenic process and cardiovascular function. INTERPRETATION Preeclampsia is related to differential cord blood DNA methylation signatures of cardiovascular pathways, including the apelin signaling pathway. The association of these cord blood DNA methylation signatures with offspring's long-term morbidities due to preeclampsia should be further investigated.

Abstract
BACKGROUND Fetal preeclampsia exposure has been associated with later cardiometabolic disease. However, this association has been investigated in few large population-wide studies, and it is unknown whether the association represents a causal relationship or is the result of shared etiological factors. METHODS To further investigate the relationship between preeclampsia exposure and later cardiometabolic disease, we identified 1 692 944 singleton infants born in Norway during 1967 to 1997, where 44 299 were exposed to preeclampsia in utero. The individuals were followed for hypertension, diabetes, and dyslipidemia as defined by dispensed medication. We used Cox regression models to calculate the association between preeclampsia exposure and cardiometabolic outcomes adjusting for measured confounders. We also used full sibling comparisons and stratified Cox regression to control for unmeasured familial confounders. RESULTS On the population level, exposed individuals had increased risk of hypertension (adjusted hazard ratio [aHR] 1.51 [95% CI, 1.41-1.63]), diabetes (aHR 1.33 [95% CI, 1.24-1.43], and dyslipidemia (aHR 1.28 [95% CI, 1.13-1.45]) compared with unexposed individuals. In sibling data, individuals not exposed to preeclampsia, but with an exposed sibling, had higher risk of hypertension and diabetes than individuals where no siblings were exposed to preeclampsia. Moreover, when comparing siblings discordant on preeclampsia exposure, there were no associations between preeclampsia and hypertension (aHR 1.05 [95% CI, 0.88-1.26]), diabetes (aHR 0.96 [95% CI, 0.80-1.14]), and dyslipidemia (aHR 0.86 [95% CI, 0.62-1.20]). CONCLUSIONS Fetal preeclampsia exposure was associated with adult life hypertension, diabetes, and dyslipidemia, but these associations were likely due to shared etiological factors, rather than exposure to the preeclamptic condition itself.

Abstract
Obesity, hypertension, type 2 diabetes mellitus and dyslipidaemia are highly prevalent among women of reproductive age and contribute to complications in >30% of pregnancies in Western countries. An accumulating body of evidence suggests that these cardiovascular disorders in women, occurring before and during their pregnancy, can affect the development of the structure, physiology and function of cardiovascular organ systems at different stages during embryonic and fetal development. These developmental adaptations might, in addition to genetics and sociodemographic and lifestyle factors, increase the susceptibility of the offspring to cardiovascular disease throughout the life course. In this Review, we discuss current knowledge of the influence of maternal cardiovascular disorders, occurring before and during pregnancy, on offspring cardiovascular development, dysfunction and disease from embryonic life until adulthood. We discuss findings from contemporary, large-scale, observational studies that provide insights into specific critical periods, evidence for causality and potential underlying mechanisms. Furthermore, we focus on priorities for future research, including defining optimal cardiovascular and reproductive health in women and men before their pregnancy and identifying specific embryonic, placental and fetal molecular developmental adaptations from early pregnancy onwards. Together, these approaches will help stop the intergenerational cycle of cardiovascular disease.

Abstract
PURPOSE OF REVIEW Health literacy is fundamental to primary and primordial prevention of atherosclerotic vascular disease (ASCVD) in children and adolescents. Here we summarize essential components of interventions which address health literacy challenges to reduce ASCVD risk in youth. RECENT FINDINGS There is a global pandemic of suboptimal health behaviors among youth that may contribute to the increasing rates of ASCVD worldwide. Deficiencies in youth cardiovascular health have promoted increased attention to health education that incorporates health literacy. Studies conducted in both the child (0 to 9 years) and adolescent (10 to 17 years) population have shown improvement in health knowledge, health behaviors such as physical activity and eating habits, and objective measures such as body mass index (BMI), blood pressure, and serum lipid levels. The available literature affirms that the involvement of family and community members in young people's surroundings-including parents, teachers, and peers-can influence educational interventions' protective effects. Educational interventions which incorporate health literacy have demonstrated potential to address ASCVD risk factors in youth and may be augmented by caregiver and community involvement.

Abstract
Adequate uteroplacental blood supply is essential for the development and growth of the placenta and fetus during pregnancy. Aberrant uteroplacental perfusion is associated with pregnancy complications such as preeclampsia, fetal growth restriction (FGR), and gestational diabetes. The regulation of uteroplacental blood flow is thus vital to the well-being of the mother and fetus. Ca2+-activated K+ (KCa) channels of small, intermediate, and large conductance participate in setting and regulating the resting membrane potential of vascular smooth muscle cells (VSMCs) and endothelial cells (ECs) and play a critical role in controlling vascular tone and blood pressure. KCa channels are important mediators of estrogen/pregnancy-induced adaptive changes in the uteroplacental circulation. Activation of the channels hyperpolarizes uteroplacental VSMCs/ECs, leading to attenuated vascular tone, blunted vasopressor responses, and increased uteroplacental blood flow. However, the regulation of uteroplacental vascular function by KCa channels is compromised in pregnancy complications. This review intends to provide a comprehensive overview of roles of KCa channels in the regulation of the uteroplacental circulation under physiological and pathophysiological conditions.

Subjects Conceived through Assisted Reproductive Technologies Display Normal Arterial Stiffness. Diagnostics (Basel) 2022; 12:diagnostics12112763.

Abstract
Multiple studies reported signs of vascular dysfunction in subjects conceived through assisted reproductive technologies (ART). The assessment of arterial stiffness in this cohort seems beneficial for risk stratification. Regional arterial stiffness of the abdominal aorta (AAO) and the common carotid arteries (CCA) was evaluated sonographically using two-dimensional speckle tracking in subjects conceived through ART and spontaneously conceived peers. Global arterial stiffness was assessed utilizing an oscillometric blood pressure device. The cohorts of 67 ART subjects and 86 spontaneously conceived peers (11.31 (8.10-18.20) years vs. 11.85 (8.72-18.27) years, p = 0.43) did not differ significantly in parameters of regional and global arterial stiffness. In the sub-analysis of study participants ≥10 years of age, markers of arterial stiffness did not display significant differences between both groups. However, a higher tendency of brachial systolic blood pressure was demonstrated in the ART cohort compared to the control group (120.18 ± 9.57 mmHg vs. 116.55 ± 8.05 mmHg, p = 0.050). The present study displayed no significant differences in arterial stiffness between ART subjects and spontaneously conceived peers. Moreover, this study suggests that arterial stiffness does not elevate more profoundly in ART subjects with increasing age. Further studies are required for a more detailed cardiovascular risk stratification of the ART cohort.

IMPORTANCE An association between maternal preeclampsia and an increased risk of cardiovascular disease in the offspring is plausible, but evidence in this area is limited. OBJECTIVE To investigate (1) the association between maternal preeclampsia and risks of ischemic heart disease (IHD) and stroke in the offspring, (2) whether the association varies by severity or timing of onset of preeclampsia, and (3) the role of preterm birth and small for gestational age (SGA) birth, both of which are related to preeclampsia and cardiovascular diseases, in this association. DESIGN, SETTING, AND PARTICIPANTS This multinational population-based cohort study obtained data from Danish, Finnish, and Swedish national registries. Live singleton births from Denmark (1973-2016), Finland (1987-2014), and Sweden (1973-2014) were followed up until December 31, 2016, in Denmark and December 31, 2014, in Finland and Sweden. Data analyses were performed between September 2020 and September 2022. EXPOSURES Preeclampsia and its subtypes, including early onset (<34 gestational weeks) and late onset (≥34 gestational weeks), severe and mild or moderate, and with and without SGA birth. MAIN OUTCOMES AND MEASURES Diagnoses of IHD and stroke were extracted from patient and cause-of-death registers. Cox proportional hazards regression models and flexible parametric survival models were used to analyze the associations. Sibling analyses were conducted to control for unmeasured familial factors. RESULTS The cohort included of 8 475 819 births (2 668 697 [31.5%] from Denmark, 1 636 116 [19.3%] from Finland, and 4 171 006 [49.2%] from Sweden, comprising 4 350 546 boys [51.3%]). Of these offspring, 188 670 (2.2%) were exposed to maternal preeclampsia, 7446 (0.1%) were diagnosed with IHD, and 10 918 (0.1%) were diagnosed with stroke during the median (IQR) follow-up of 19.3 (9.0-28.1) years. Offspring of individuals with preeclampsia had increased risks of IHD (adjusted hazard ratio [HR], 1.33; 95% CI, 1.12-1.58) and stroke (adjusted HR, 1.34; 95% CI, 1.17-1.52). These associations were largely independent of preterm or SGA birth. Severe forms of preeclampsia were associated with a higher stroke risk than less severe forms (severe vs mild or moderate: adjusted HR, 1.81 [95% CI, 1.41-2.32] vs 1.22 [95% CI, 1.05-1.42]; early vs late onset: adjusted HR, 2.55 [95% CI, 1.97-3.28] vs 1.18 [95% CI, 1.01-1.39]; with vs without SGA birth: adjusted HR, 1.84 [95% CI, 1.44-2.34] vs 1.25 [95% CI, 1.07-1.48]). Sibling analyses suggested that the associations were partially explained by unmeasured familial factors. CONCLUSIONS AND RELEVANCE Results of this study suggest that offspring born to individuals with preeclampsia had increased IHD and stroke risk that were not fully explained by preterm or SGA birth, and that the associated risks for stroke were higher for severe forms of preeclampsia.

Abstract
OBJECTIVES We aimed to assess women's perceptions on the long-term risks for cardiovascular disease (CVD) after major pregnancy complications. METHODS Women who experienced major pregnancy complications and those who experienced uncomplicated pregnancies were invited to participate in a qualitative study. Focus group discussions (FGDs) and self-administered questionnaires were used to explore: The knowledge of long-term sequelae after experiencing a major pregnancy complication; Importance of education on heart health; The practicality of referral to a clinic after pregnancy complications; Willingness for regular postpartum clinic visits after pregnancy complications. A thematic qualitative analysis was undertaken. RESULTS 26 women participated in four FGDs. The majority of women did not know of the association between major pregnancy complications and CVD. The main views expressed were: Women who experience pregnancy complications should receive education on improving heart health; An appointment for the first CVD risk screening visit needs to be made prior to discharge from the delivery suite; Women will benefit by having the option to select between a hospital and a general-practitioner based model of follow up. CONCLUSIONS These views are important in developing postpartum strategies to reduce CVD risk among women who experience pregnancy complications.

Abstract
Endothelial dysfunction, impaired implantation and placental insufficiency have been identified as mechanisms behind the development of pre-eclampsia, resulting in angiogenic factors' alteration. Angiogenic imbalance is also associated with congenital heart defects, and this common physiologic pathway may explain the association between them and pre-eclampsia. This review aims to understand the physiology shared by these two entities and whether women with pre-eclampsia have an increased risk of fetal congenital heart defects (or the opposite). The present research has highlighted multiple vasculogenic pathways associated with heart defects and preeclampsia, but also epigenetic and environmental factors, contributing both. It is also known that fetuses with a prenatal diagnosis of congenital heart disease have an increased risk of several comorbidities, including intrauterine growth restriction. Moreover, the impact of pre-eclampsia goes beyond pregnancy as it increases the risk for following pregnancies and for diseases later in life in both offspring and mothers. Given the morbidity and mortality associated with these conditions, it is of foremost importance to understand how they are related and its causative mechanisms. This knowledge may allow earlier diagnosis, an adequate surveillance or even the implementation of preventive strategies.

Preeclampsia and high blood pressure in early pregnancy as risk factors of severe maternal cardiovascular disease during 50-years of follow-up. Pregnancy Hypertens 2021; 26:79-85.

Abstract
OBJECTIVES Studies suggest preeclampsia as a risk factor for long term cardiovascular diseases (CVD), while evidence is limited regarding the risk of high blood pressures (BP) in early pregnancy. STUDY DESIGN A register-based follow-up of 2434 mothers in the Helsingborg Birth Cohort. Associations of high BP in early pregnancy (>95th percentile systolic [SBP], diastolic [BDP], or mean arterial BP [MAP]) during the first antenatal visit and/or preeclampsia with an incident CVD event (ischemic heart disease or stroke) were assessed. To model risks and adjust for co-variables, Cox proportional hazard regression was used. RESULTS Of the included women, 120 (4.9%) had high SBP, 49 (2%) high DBP, 104 (4.3%) high MAP in early pregnancy; and 115 (4.7%) developed preeclampsia. During 52 years of follow-up, totalling 121,457 person-years, 534 (21.9%) women experienced a CVD event. Women with preeclampsia had a higher risk of developing CVD compared to women without preeclampsia (HR 1.5, 95%CI: 1.1-2.2), while risks among women with high BPs were slightly higher. In adjusted analysis, risk estimates were approximately 50% higher than that of the reference groups for all four studied exposures. Of women with later CVD, 35 (6.6%) had preeclampsia, and another 31 (5,8%) women high SBP or high MAP. Without later preeclampsia, high SBP constituted a significant risk factor (HR 1.6, 95%CI: 1.1-2.4) for CVD. CONCLUSIONS Women with SBP > 95th percentile in early pregnancy, but without later preeclampsia, have a higher risk of developing CVD that is comparable to women with history of preeclampsia.

Abstract
Uteroplacental blood flow increases as pregnancy advances. Adequate supply of nutrients and oxygen carried by uteroplacental blood flow is essential for the well-being of the mother and growth/development of the fetus. The uteroplacental hemodynamic change is accomplished primarily through uterine vascular adaptation, involving hormonal regulation of myogenic tone, vasoreactivity, release of vasoactive factors and others, in addition to the remodeling of spiral arteries. In preeclampsia, hormonal and angiogenic imbalance, proinflammatory cytokines and autoantibodies cause dysfunction of both endothelium and vascular smooth muscle cells of the uteroplacental vasculature. Consequently, the vascular dysfunction leads to increased vascular resistance and reduced blood flow in the uteroplacental circulation. In this article, the (mal)adaptation of uteroplacental vascular function in normal pregnancy and preeclampsia and underlying mechanisms are reviewed.

Abstract
There is growing evidence of long-term cardiovascular sequelae in children after in utero exposure to preeclampsia. Maternal hypertension and/or placental ischaemia during pregnancy increase the risk of hypertension, stroke, diabetes, and cardiovascular disease (CVD) in the offspring later in life. The mechanisms associated with CVD seem to be a combination of genetic, molecular, and environmental factors which can be defined as fetal and postnatal programming. The aim of this paper is to discuss the relationship between pregnancy complicated by preeclampsia and possibility of CVD in the offspring. Unfortunately, due to its multifactorial nature, a clear dependency mechanism between preeclampsia and CVD is difficult to establish.

Abstract
BACKGROUND Keeping in view the developmental origin of health and disease hypothesis, the aim of this study was to assess differences in cardiac and vascular structure and function in children exposed to preeclampsia in utero compared with those of normotensive mothers. The hypothesis under investigation was that children exposed to preeclampsia would have altered cardiac and vascular structure and function compared with the unexposed group. METHODS This was a retrospective cohort study that included children 2 to 10 years of age born to mothers with and without exposure to preeclampsia in utero (n = 80 in each group). Myocardial morphology and function using echocardiography and carotid intima-media thickness and pulse-wave velocity were determined. Multivariate linear regression was used to compare preeclampsia-exposed and nonexposed groups. Subgroup analysis to assess differences between early- and late-onset preeclampsia was also performed. RESULTS Forty-one percent of mothers (n = 33) had early-onset preeclampsia. Children in the exposed group had a significantly higher prevalence of stage 1 systolic and diastolic hypertension (22% [n = 18] and 35% [n = 18], respectively) compared with the unexposed group (9% [n = 7] and 19% [n = 15], respectively; P = .01). Children in the exposed group also had higher pulse-wave velocity compared with those in the unexposed group (0.42 ± 0.1 vs 0.39 ± 0.1, P = .03). Subgroup analysis revealed that changes in blood pressure and pulse-wave velocity were determined primarily by early-onset preeclampsia. There was no significant difference in cardiac morphology or systolic and diastolic function between the exposed and unexposed groups. CONCLUSION In utero exposure to preeclampsia has an effect on vascular function in children aged 2 to 10 years, related primarily to early-onset disease. Routine blood pressure screening should be recommended for such children.

Abstract
KEY POINTS Maternal shift work increases the risk of pregnancy complications, although its effects on progeny health after birth are not clear. We evaluated the impact of a simulated shift work protocol for one-third, two-thirds or all of pregnancy on the metabolic health of sheep progeny. Simulated shift work had no effect on growth, body size, body composition or glucose tolerance in pre-pubertal or young adult progeny. Glucose-stimulated insulin secretion was reduced in adult female progeny and insulin sensitivity was increased in adult female singleton progeny. The results of the present study do not support the hypothesis that maternal shift work exposure impairs metabolic health of progeny in altricial species. ABSTRACT Disrupted maternal circadian rhythms, such as those experienced during shift work, are associated with impaired progeny metabolism in rodents. The effects of disrupted maternal circadian rhythms on progeny metabolism have not been assessed in altricial, non-litter bearing species. We therefore assessed postnatal growth from birth to adulthood, as well as body composition, glucose tolerance, insulin secretion and insulin sensitivity, in pre-pubertal and young adult progeny of sheep exposed to control conditions (CON: 10 males, 10 females) or to a simulated shift work (SSW) protocol for the first one-third (SSW0-7: 11 males, 9 females), the first two-thirds (SSW0-14: 8 males, 11 females) or all (SSW0-21: 8 males, 13 females) of pregnancy. Progeny growth did not differ between maternal treatments. In pre-pubertal progeny (12-14 weeks of age), adiposity, glucose tolerance and insulin secretion during an i.v. glucose tolerance test and insulin sensitivity did not differ between maternal treatments. Similarly, in young adult progeny (12-14 months of age), food intake, adiposity and glucose tolerance did not differ between maternal treatments. At this age, however, insulin secretion in response to a glucose bolus was 30% lower in female progeny in the combined SSW groups compared to control females (P = 0.031), and insulin sensitivity of SSW0-21 singleton females was 236% compared to that of CON singleton female progeny (P = 0.025). At least in this model, maternal SSW does not impair progeny metabolic health, with some evidence of greater insulin action in female young adult progeny.

Abstract
BACKGROUND The incidence of preeclampsia, which may cause significant maternal and perinatal morbidity, has risen in recent years, therefore it is critical to identify women at risk for preeclampsia. We aimed to identify risk factors in the first pregnancy (not complicated by preeclampsia) for preeclampsia in the subsequent pregnancy. METHODS A retrospective population-based nested case-control study was conducted, including all women with first (P1) and second (P2) singleton consecutive deliveries. Women who had experienced preeclampsia in their first pregnancy were excluded. Cases were defined as women with preeclampsia in their second pregnancy, and were compared to the controls, defined as women without this diagnosis in second pregnancy. Characteristics and complications of the first pregnancy were compared between cases and controls, and multivariable regression models were used to study the association between pregnancy complications (in the first pregnancy) and preeclampsia (in the subsequent pregnancy), while adjusting for confounders. RESULTS A total of 40,673 women were included in the study, 1.5% of second pregnancies were diagnosed with preeclampsia (n = 627, i.e., Cases). Cases, as compared to controls were older in their 1st pregnancy, with longer inter-pregnancy interval, and were more likely to have the following complications in their first pregnancy: preterm delivery (15.0% vs. 7.7%), low birthweight (17.9% vs. 10.3%), perinatal mortality (3.2% vs. 1.1%), and gestational diabetes (7.0% vs. 2.7%). In the multivariable model, adjusted for maternal age, obesity and inter-pregnancy interval, either one of these first pregnancy complications were independently associated with an increased risk for preeclampsia (adjusted OR for either of first pregnancy complication =1.73; 95% CI 1.37-2.14, <0.001), and the risk was greater for each additional complication (adjusted OR for ≥2 risk factors =3.54; 95% CI 2.28-5.52, p < 0.001). CONCLUSIONS Complications in first pregnancy, including preterm delivery, perinatal mortality and gestational diabetes, are risk factors for primary preeclampsia in second pregnancy. First pregnancy may serve as a window of opportunity to identify women at risk for future preeclampsia and other morbidities later in life.

Abstract
Preeclampsia is a common pregnancy complication, affecting 2% to 8% of pregnancies worldwide, and is an important cause of both maternal and fetal morbidity and mortality. Importantly, although aspirin and calcium are able to prevent preeclampsia in some women, there is no cure apart from delivery of the placenta and fetus, often necessitating iatrogenic preterm birth. Preclinical models of preeclampsia are widely used to investigate the causes and consequences of preeclampsia and to evaluate safety and efficacy of potential preventative and therapeutic interventions. In this review, we provide a summary of the published preclinical models of preeclampsia that meet human diagnostic criteria, including the development of maternal hypertension, together with new-onset proteinuria, maternal organ dysfunction, and uteroplacental dysfunction. We then discuss evidence from preclinical models for multiple causal factors of preeclampsia, including those implicated in early-onset and late-onset preeclampsia. Next, we discuss the impact of exposure to a preeclampsia-like environment for later maternal and progeny health. The presence of long-term impairment, particularly cardiovascular outcomes, in mothers and progeny after an experimentally induced preeclampsia-like pregnancy, implies that later onset or reduced severity of preeclampsia will improve later maternal and progeny health. Finally, we summarize published intervention studies in preclinical models and identify gaps in knowledge that we consider should be targets for future research.
