Abstract
OBJECTIVE To assess the impact of low-dose aspirin (LDA) starting in early pregnancy on delaying preterm hypertensive disorders of pregnancy. DESIGN Non-prespecified secondary analysis of a randomised masked trial of LDA. SETTING The study was conducted among women in the Global Network for Women's and Children's Health's Maternal and Newborn Health Registry (MNHR) clusters, a prospective, population-based study in Kenya, Zambia, the Democratic Republic of the Congo (DRC), Pakistan, India (two sites-Belagavi and Nagpur) and Guatemala. POPULATION Nulliparous singleton pregnancies between 6+0 weeks and 13+6 weeks in six low-middle income countries (Democratic Republic of Congo, Guatemala, India, Kenya, Pakistan, Zambia) enrolled in the ASPIRIN Trial. METHODS We compared the incidence of HDP at delivery at three gestational age periods (<28, <34 and <37 weeks) between women who were randomised to aspirin or placebo. Women were included if they were randomised and had an outcome at or beyond 20 weeks (Modified Intent to Treat). MAIN OUTCOME MEASURES Our primary outcome was pregnancies with HDP associated with preterm delivery (HDP@delivery) before <28, <34 and <37 weeks. Secondary outcomes included small for gestational age (SGA) <10th percentile, <5th percentile, and perinatal mortality. RESULTS Among the 11 976 pregnancies, LDA did not significantly lower HDP@delivery <28 weeks (relative risk [RR] 0.18, 95% confidence interval [CI] 0.02-1.52); however, it did lower HDP@delivery <34 weeks (RR 0.37, 95% CI 0.17-0.81) and HDP@delivery <37 weeks (RR 0.66, 95% CI 0.49-0.90). The overall rate of HDP did not differ between the two groups (RR 1.08, 95% CI 0.94-1.25). Among those pregnancies who had HDP, SGA <10th percentile was reduced (RR 0.81, 95% CI 0.67-0.99), though SGA <5th percentile was not (RR 0.84, 95% CI 0.64-1.09). Similarly, perinatal mortality among pregnancies with HDP occurred less frequently (RR 0.55, 95% CI 0.33-0.92) in those receiving LDA. Pregnancies randomised to LDA delivered later with HDP compared with those receiving placebo (median gestational age 38.5 weeks vs. 37.9 weeks; p = 0.022). CONCLUSIONS In this secondary analysis of a study of low-risk nulliparous singleton pregnancies, early administration of LDA resulted in lower rates of preterm HDP and delivery before 34 and 37 weeks but not in the overall rate of HDP. These results suggest that LDA works in part by delaying HDP.

Abstract
BACKGROUND Women with adverse pregnancy outcomes may have higher subsequent risk of chronic kidney disease, but the long-term independent risks and potential causality are unclear. OBJECTIVE This study aimed to determine long-term risks of chronic kidney disease associated with 5 major adverse pregnancy outcomes in a large population-based cohort, and to assess for familial confounding using co-sibling analyses. STUDY DESIGN A national cohort study was conducted of all 2,201,279 women with a singleton delivery in Sweden from 1973 to 2015, followed up for chronic kidney disease identified from nationwide diagnoses through 2018. Cox regression was used to compute hazard ratios for chronic kidney disease associated with preterm delivery, small for gestational age, preeclampsia, other hypertensive disorders, and gestational diabetes, adjusting for other adverse pregnancy outcomes and maternal factors. Co-sibling analyses assessed for potential confounding by shared familial (genetic or environmental) factors. RESULTS In 56 million person-years of follow-up, 11,572 (0.5%) women were diagnosed with chronic kidney disease (median age, 61 years). All 5 adverse pregnancy outcomes were independently associated with increased chronic kidney disease risk. Within 10 years following delivery, adjusted hazard ratios associated with specific adverse pregnancy outcomes were: 7.12 for other hypertensive disorders (95% confidence interval, 5.88-8.62), 4.38 for preeclampsia (3.72-5.16), 3.50 for preterm delivery (2.95-4.15), 3.15 for gestational diabetes (2.53-3.92), and 1.22 for small for gestational age (1.02-1.44). All hazard ratios remained significantly elevated even 30 to 46 years after delivery (gestational diabetes, 3.32 [95% confidence interval, 2.96-3.72]; other hypertensive disorders, 2.44 [1.91-3.11]; preeclampsia, 2.03 [1.90-2.16]; preterm delivery, 1.56 [1.44-1.68]; and small for gestational age, 1.24 [1.16-1.31]). These findings were only partially (0%-45%) explained by shared familial factors. Women with multiple adverse pregnancy outcomes had further increases in risk. CONCLUSION In this large national cohort, women who experienced any of 5 major adverse pregnancy outcomes had increased risk for chronic kidney disease up to 46 years later. Women with adverse pregnancy outcomes need early preventive actions and long-term monitoring to reduce risk of chronic kidney disease.

Abstract
BACKGROUND Recent literature suggest the effect of maternal smoking on risk of hypertensive disorders in pregnancy (HDP) and preeclampsia may differ by ethnicity; however, studies on Asians are limited. METHODS We investigated the association of maternal smoking with HDP and preeclampsia using a common analysis protocol to analyze the association in six birth cohorts participating in a Japanese consortium of birth cohorts (JBiCC). Results were compared with-published results from cohorts not included in this consortium, and, where possible, we produced a meta-analysis including these studies. RESULTS Meta-analysis of four cohort studies including 28,219 participants produced an odds ratio (OR) of 1.24 (95% confidence interval [CI], 0.88-1.87) for the effect of smoking beyond early pregnancy compared to women who did not smoke during pregnancy. These results combined with those from the Japan Environment and Children's Study (JECS) yielded an OR of 1.19 (95% CI, 1.00-1.43, P = 0.056). Meta-analysis results for categories of smoking volume were insignificant, but when combined with JECS yielded an OR of 0.86 (95% CI, 0.65-1.12) for smoking 1-4 cigarettes, 1.25 (95% CI, 0.98-1.60) for smoking 5-9 cigarettes, and 1.27 (95% CI, 1.04-1.54) for smoking 10 or more cigarettes per day. All effects were insignificant for preeclampsia. CONCLUSION Our results suggest that the protective effects of smoking longer and smoking more on HDP and preeclampsia repeatedly observed among Europeans and North Americans likely do not hold for the Japanese.

Abstract
Background Cardiovascular dysfunction and hypertension can persist postpartum following hypertensive disorders of pregnancy (HDPs). This study hypothesized that activin A, proinflammatory markers and concentric remodeling by echo would be higher 1-2 years postpartum following HDP with persistent hypertension compared to HDP with normalized blood pressure (BP). We further hypothesized correlations between biomarkers with BP and echocardiographic indices. Methods and Results This study enrolled participants with HDPs but no prepregnancy hypertension followed 1 to 2 years after delivery. Activin A and inflammatory cytokines, BP, and echocardiograms were obtained. Biomarker concentrations and echocardiographic parameters were compared between HDP with and without persistent hypertension. Individuals with persistent hypertension at a mean of 1.6 years postpartum had significantly higher activin A concentrations (median[interquartile range 25-75] 230.6 [196.0-260.9] versus 175.3 pg/mL [164.3-188.4]; P<0.01), more concentric left ventricular concentric remodeling (relative wall thickness >0.42, 48% versus 7%; P<0.01), and worse peak left atrial strain (33.4% versus 39.3%; P<0.05) as compared with those whose BP normalized. Higher activin A and interleukin-6 concentrations correlated with higher systolic (activin A: r=0.43, P=0.01) and diastolic BP (activin A: r=0.58, P<0.01; interleukin-6: r=0.36; P<0.05), as well as greater left ventricular thickness (activin A and interventricular septal thickness: r=0.41, interleukin-6 and interventricular septal thickness: r=0.36; both P<0.05). Conclusions Individuals with HDPs and persistent hypertension had significantly higher activin A and greater concentric remodeling compared with those with HDPs and normalized BP at 1 to 2 years postpartum. Activin A was positively correlated with both BP and echocardiographic indices (left ventricular thickness), suggesting overlapping processes between persistent hypertension and cardiac remodeling.

Abstract
STUDY QUESTION Is intertwin birth weight discordance associated with adverse maternal and perinatal outcomes following frozen embryo transfer (FET)? SUMMARY ANSWER For twins conceived following FET, intertwin birth weight discordance is related to elevated risks of neonatal mortality irrespective of chorionicity, and the risk of hypertensive disorders of pregnancy (HDP) is elevated for the mothers of dichorionic twins affected by such birth weight discordance. WHAT IS KNOWN ALREADY While the relationships between intertwin birth weight discordance and adverse maternal or fetal outcomes have been studied for naturally conceived twins, similarly comprehensive analyses for twins conceived using ART remain to be performed. STUDY DESIGN, SIZE, DURATION This was a retrospective cohort study of all twin births from 2007 to 2021 at Shanghai Ninth People's Hospital in Shanghai, China that were conceived following FET (N = 6265). PARTICIPANTS/MATERIALS, SETTING, METHODS Intertwin birth weight discordance was defined as a 20% difference in neonatal birth weights. The primary study outcome was the incidence of HDP and neonatal death while secondary outcomes included gestational diabetes, placenta previa, placental abruption, intrahepatic cholestasis of pregnancy, preterm premature rupture of the membranes, Cesarean delivery, gestational age, birth weight, stillbirth, birth defect, neonatal jaundice, necrotizing enterocolitis, and pneumonia incidence. Logistic regression models were used to estimate adjusted odds ratios (aORs) and 95% CIs for maternal and neonatal outcomes. Subgroup analyses were conducted, and Kaplan-Meier survival analysis was used to estimate the survival probability. The sensitivity analysis was performed with a propensity score-based patient-matching model, an inverse probability weighting model, a restricted cubic spline analysis, and logistic regression models using other percentage cutoffs for discordance. MAIN RESULTS AND THE ROLE OF CHANCE Of 6101 females that gave birth to dichorionic twins during the study interval, birth weight discordance was observed in 797 twin pairs (13.1%). In this cohort, intertwin birth weight discordance was related to an elevated risk of HDP (aOR 1.56; 95% CI 1.21-2.00), and this relationship was confirmed through sensitivity analyses. Hypertensive disease risk rose as the severity of this birth weight discordance increased. Discordant birth weight was also linked to increased odds of neonatal mortality (aOR 2.13; 95% CI 1.03-4.09) and this risk also increased with the severity of discordance. Of the 164 women with monochorionic twins, the discordant group exhibited an elevated risk of neonatal death compared to the concordant group (crude OR 9.00; 95% CI 1.02-79.3). LIMITATIONS, REASONS FOR CAUTION The limitations of this study are its retrospective nature and the fact that the available data could not specify which twins were affected by adverse outcomes. There is a lack of an established reference birth weight for Chinese twins born at a gestational age of 24-41 weeks. WIDER IMPLICATIONS OF THE FINDINGS These findings suggest that twins exhibiting a birth weight discordance are related to an elevated risk of adverse maternal and perinatal outcomes, emphasizing a potential need for higher levels of antenatal surveillance in these at-risk pregnancies. STUDY FUNDING/COMPETING INTEREST(S) Authors declare no conflict of interest. This study was funded by the Clinical Research Program of Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine (JYLJ202118) and the National Natural Science Foundation of China (Grant Nos 82271693 and 82273634).

Abstract
Hypertensive Disorders and Stroke in Black WomenIn 42,924 U.S. Black women enrolled in 1995, there were 1555 incident strokes, including 310 among 4938 women with a history of hypertensive disorders of pregnancy. This association may help explain the disproportionately higher stroke incidence in Black women given the higher prevalence of hypertensive disorders of pregnancy in this population.

Abstract
OBJECTIVE The study aimed to determine whether maternal serum haptoglobin values could have an effect on predicting diagnosis and neonatal outcomes in preeclampsia and HELLP syndrome. MATERIALS AND METHODS Hundred sixteen pregnant women who met the inclusion criteria were included in the study. To evaluate whether serum haptoglobin level in maternal blood could be used in early diagnosis of preeclampsia and HELLP syndrome, 49 pregnant women diagnosed with preeclampsia and 13 pregnant women diagnosed with HELLP syndrome were included in the study group, and 54 healthy pregnant women in the control group. The groups were compared regarding maternal serum haptoglobin level, platelet count, ALT, AST, LDH, and uric acid levels. Moreover, the age, obstetric histories, and newborn outcomes of all pregnant women were recorded and compared between groups. RESULTS The mean haptoglobin values were 0.29 ± 0.23 g/L in the HELLP syndrome group, 1.01 ± 0.52 g/L in the preeclampsia group, and 1.16 ± 0.37 g/L in the control group. The mean haptoglobin result was lower in the HELLP syndrome group compared to the preeclampsia and control groups (p < 0.001). While the differences between HELLP syndrome and the control and preeclampsia groups were statistically significant, no significant difference was determined between the preeclampsia and control groups. There was a significant positive correlation between haptoglobin value with the week of delivery, umbilical cord pH value, and the first and fifth-minute Apgar scores (p < 0.05). CONCLUSION It was concluded that haptoglobin values could be used together with other biochemical parameters to diagnose HELLP syndrome and predict newborn outcomes.

Abstract
About 3% of all pregnancies occur in patients with some degree of chronic kidney disease (CKD) and, in turn, CKD is a risk factor for developing hypertensive disorders of pregnancies (HDP) and unfavorable pregnancy outcomes, at both the maternal and fetal level. CKD is often characterized by proteinuria and proteinuria is a risk factor for HDP. However, even if the positive correlation between proteinuria and unfavorable pregnancy outcomes is well acknowledged, the degree of proteinuria associated with adverse outcomes is still a matter of debate. In this issue of the Journal, Li et al. present a retrospective study that shows that >1 g of proteinuria/day is associated with worse maternal outcomes while >2 g/day with worse fetal ones. This study gives proteinuria thresholds for unfavorable outcomes in pregnant CKD patients, but it should be kept in mind that there is a linear correlation between proteinuria and worse pregnancy outcomes, thus a strict surveillance during the entire gestation should be advised independently of the proteinuria level.

Abstract
OBJECTIVE To examine the outcomes of the subsequent pregnancies from women with a previous pregnancy-associated stroke (PAS) in comparison to matched controls. DESIGN Population-based retrospective cohort study. SETTING AND POPULATION All women with a PAS in Finland 1987-2016 (n = 235) and controls (n = 694). METHODS We identified all subsequent deliveries and induced and spontaneous abortions for women with a previous PAS and their matched controls from the Medical Birth Register and the Hospital Discharge Register until 2016. The number, course and outcomes of the subsequent pregnancies were compared. Patient records were studied for PAS recurrence. MAIN OUTCOME MEASURES PAS recurrence and pregnancy complications. RESULTS Women with a previous PAS had fewer subsequent deliveries: 73 (31.1%) women had 122 deliveries in all, whereas 303 (47.3%) of the controls had 442 deliveries (age-adjusted odds ratio [OR] 0.54, 95% CI 0.38-0.76). Hypertensive disorders of pregnancy (HDP) (17.2% versus 5.7%, age-adjusted OR 4.0, 95% CI 1.7-9.3), especially chronic hypertension (age-adjusted OR 5.9, 95% CI 1.5-24.7), and any diabetes during pregnancy (24.6% versus 14.5%, age-adjusted OR 2.0, 95% CI 1.1-3.8) were more common in cases. Regarding HDP, the difference between groups was explained by underlying factors such as index pregnancy HDP (multivariable OR 2.4, 95% CI 0.8-6.7). PAS recurred in four cases (5.5%). CONCLUSIONS Subsequent pregnancies of women with a history of PAS are more often complicated with hypertensive disorders of pregnancy and any diabetes during pregnancy. PAS recurrence risk is considerable.

Abstract
Introduction Recruiting women with a family history (FH) of hypertensive disorders of pregnancy (HDP) to participate in research before pregnancy could offer insight into genetic and lifestyle factors that incur higher risk of cardiovascular disease during pregnancy and throughout the life course. Methods The Sisterhood Study piloted low-touch, remote recruitment strategies that relied on women with a history of preeclampsia to share study information with family and friends. It aimed to enroll 150 women with a FH of HDP and 150 controls. Results The study recruited 328 women (104 with a FH of HDP, 131 without a FH, and 93 with unknown FH) prior to pregnancy. The majority identified as non-Hispanic White (74.7%) and had > high school education (91.8%). Discussion Although the population was enriched with nulliparous women with a FH of HDP, it was not sufficient to recruit a diverse cohort large enough to meet the study aim.

Abstract
BACKGROUND Women with hypertensive disorders of pregnancy (HDP) have a significantly higher risk of developing cardiovascular diseases later in life. The stratification of this risk using biomarkers during pregnancy can help to identify these women and apply early prevention. OBJECTIVE We aimed to determine proinflammatory cytokines and angiogenic markers, echocardiographic parameter changes after delivery and predict early cardiovascular disease risk in women with arterial hypertension and its complications during pregnancy. METHODS We conducted a literature search using the PubMed database for the last ten years. A total of 17 articles were included to our study and full text reviewed. RESULTS Four out of six studies found higher postpartum Interleukin-6 (IL-6) levels in women with HDP. IL-6 correlated positively with waist circumference, body mass index, and triglycerides, and negatively with high density lipoproteins (HDL). Two out of four studies found higher postpartum tumor necrosis factor alpha (TNF-α) levels in women with HDP but later concentration equalizes. One out of eight studies found higher placental growth factor (PlGF) and two out of eight found more elevated soluble fms-like tyrosine kinase-1 (sFlt-1) in women with HDP. With decreasing PlGF and increasing sFlt-1, common carotid artery intima and media thickness, aortic root diameter, left atrial diameter, left ventricle mass, systolic, diastolic, and mean blood pressure increased, whereas HDL decreased. One out of four studies found higher sFlt-1/PlGF. CONCLUSION IL-6 remains significantly higher after delivery. Few studies found higher TNF-α, sFlt-1, PlGF and their ratio postpartum. All studies found a correlation between angiogenic factors, IL-6, and cardiovascular disease risk factors.

Abstract
BACKGROUND Catestatin has been identified as an important factor in blood pressure control in non-pregnant adults. A possible impact on the development of hypertensive disorders of pregnancy has been indicated. Data on catestatin levels in pregnancy are scarce. The aim of this study was to investigate a potential association of maternal serum catestatin levels to the pathogenesis of preeclampsia. METHODS We evaluated serum catestatin levels of 50 preeclamptic singleton pregnancies and 50 healthy gestational-age-matched pregnancies included in the obstetric biobank registry of the Medical University of Vienna. Receiver operating characteristic curves and logistic regression models were performed to investigate an association between catestatin levels and development of preeclampsia. RESULTS Catestatin levels were significantly decreased in women with preeclampsia compared to healthy controls (median CST: 3.03 ng/mL, IQR [1.24-7.21 ng/mL] vs. 4.82 ng/mL, IQR [1.82-10.02 ng/mL]; p = 0.010), indicating an association between decreased catestatin values and the development of preeclampsia. There was no significant difference in catestatin values between early-onset preeclampsia and late-onset preeclampsia. Modelling the occurrence of preeclampsia via logistic regression was improved when adding catestatin as a predictive factor. CONCLUSIONS Decreased serum catestatin levels are associated with the presence of preeclampsia. Further investigations into the diagnostic value and possible therapeutic role of catestatin in preeclampsia are warranted.

Abstract
BACKGROUND The number of frozen embryo transfers (FET) has increased dramatically over the past decade. Based on current evidence, there is no difference in pregnancy rates when natural cycle FET (NC-FET) is compared to artificial cycle FET (AC-FET) in subfertile women. However, NC-FET seems to be associated with lower risk of adverse obstetric and neonatal outcomes compared with AC-FET cycles. Currently, there is no consensus about whether NC-FET needs to be combined with luteal phase support (LPS) or not. The question of how to prepare the endometrium for FET has now gained even more importance and taken the dimension of safety into account as it should not simply be reduced to the basic question of effectiveness. OBJECTIVE AND RATIONALE The objective of this project was to determine whether NC-FET, with or without LPS, decreases the risk of adverse obstetric and neonatal outcomes compared with AC-FET. SEARCH METHODS A systematic review and meta-analysis was carried out. A literature search was performed using the following databases: CINAHL, EMBASE, and MEDLINE from inception to 10 October 2022. Observational studies, including cohort studies, and registries comparing obstetric and neonatal outcomes between singleton pregnancies after NC-FET and those after AC-FET were sought. Risk of bias was assessed using the ROBINS-I tool. The quality of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach. We calculated pooled odds ratios (ORs), pooled risk differences (RDs), pooled adjusted ORs, and prevalence estimates with 95% CI using a random effect model, while heterogeneity was assessed by the I2. OUTCOMES The conducted search identified 2436 studies, 890 duplicates were removed and 1546 studies were screened. Thirty studies (NC-FET n = 56 445; AC-FET n = 57 231) were included, 19 of which used LPS in NC-FET. Birthweight was lower following NC-FET versus AC-FET (mean difference 26.35 g; 95% CI 11.61-41.08, I2 = 63%). Furthermore NC-FET compared to AC-FET resulted in a lower risk of large for gestational age (OR 0.88, 95% 0.83-0.94, I2 = 54%), macrosomia (OR 0.81; 95% CI 0.71-0.93, I2 = 68%), low birthweight (OR 0.81, 95% CI 0.77-0.85, I2 = 41%), early pregnancy loss (OR 0.73; 95% CI 0.61-0.86, I2 = 70%), preterm birth (OR 0.80; 95% CI 0.75-0.85, I2 = 20%), very preterm birth (OR 0.66, 95% CI 0.53-0.84, I2 = 0%), hypertensive disorders of pregnancy (OR 0.60, 95% CI 0.50-0.65, I2 = 61%), pre-eclampsia (OR 0.50; 95% CI 0.42-0.60, I2 = 44%), placenta previa (OR 0.84, 95% CI 0.73-0.97, I2 = 0%), and postpartum hemorrhage (OR 0.43; 95% CI 0.38-0.48, I2 = 53%). Stratified analyses on LPS use in NC-FET suggested that, compared to AC-FET, NC-FET with LPS decreased preterm birth risk, while NC-FET without LPS did not (OR 0.75, 95% CI 0.70-0.81). LPS use did not modify the other outcomes. Heterogeneity varied from low to high, while quality of the evidence was very low to moderate. WIDER IMPLICATIONS This study confirms that NC-FET decreases the risk of adverse obstetric and neonatal outcomes compared with AC-FET. We estimate that for each adverse outcome, use of NC-FET may prevent 4 to 22 cases per 1000 women. Consequently, NC-FET should be the preferred treatment in women with ovulatory cycles undergoing FET. Based on very low quality of evidence, the risk of preterm birth be decreased when LPS is used in NC-FET compared to AC-FET. However, because of many uncertainties-the major being the debate about efficacy of the use of LPS-future research is needed on efficacy and safety of LPS and no recommendation can be made about the use of LPS.

Abstract
Preeclampsia is a multisystemic disorder of pregnancy that affects 250,000 pregnant individuals in the United States and approximately 10 million worldwide per annum. Preeclampsia is associated with substantial immediate morbidity and mortality but also long-term morbidity for both mother and offspring. It is now clearly established that a low dose of aspirin given daily, beginning early in pregnancy modestly reduces the occurrence of preeclampsia. Low-dose aspirin seems safe, but because there is a paucity of information about long-term effects on the infant, it is not recommended for all pregnant individuals. Thus, several expert groups have identified clinical factors that indicate sufficient risk to recommend low-dose aspirin preventive therapy. These risk factors may be complemented by biochemical and/or biophysical tests that either indicate increased probability of preeclampsia in individuals with clinical risk factors, or more importantly, identify increased likelihood in those without other evident risk. In addition, the opportunity exists to provide this population with additional care that may prevent or mitigate the short- and long-term effects of preeclampsia. Patient and provider education, increased surveillance, behavioral modification, and other approaches to improve outcomes in these individuals can improve the chance of a healthy outcome. We assembled a group with diverse, relevant expertise (clinicians, investigators, advocates, and public and private stakeholders) to develop a care plan in which providers and pregnant individuals at risk can work together to reduce the risk of preeclampsia and associated morbidities. The plan is for care of individuals at moderate to high risk for developing preeclampsia, sufficient to receive low-dose aspirin therapy, as identified by clinical and/or laboratory findings. The recommendations are presented using the GRADE methodology with the quality of evidence upon which each is based. In addition, printable appendices with concise summaries of the care plan's recommendations for patients and healthcare providers are provided. We believe that this shared approach to care will facilitate prevention of preeclampsia and its attendant short- and long-term morbidity in patients identified as at risk for development of this disorder.

Abstract
OBJECTIVE The aim of this study was to examine the association of timing of antiretroviral therapy (ART) initiation and ART class with risk of new-onset hypertensive disorders of pregnancy (HDP) among people with HIV (PWH). DESIGN An observational study of participants in the multisite Surveillance Monitoring for ART Toxicities (SMARTT) study. METHODS Data were abstracted from medical records of pregnant PWH enrolled in SMARTT (January 30, 2015 to March 25, 2019). New-onset HDP included gestational hypertension, preeclampsia/eclampsia, or HELLP syndrome. We examined the associations of clinical risk factors and three exposures of interest, each in a separate model, with risk of new-onset HDP. Log-binomial regression models were fit using generalized estimating equations to account for correlations within people. Exposures included timing of ART initiation, antiretroviral class among those on therapy at conception, and antiretroviral class among those initiating treatment during pregnancy. RESULTS Of 1038 pregnancies in this cohort, 973 were singletons with complete data on HDP, with ART use in 948. Overall, 9% had a new-onset HDP, 10% had chronic hypertension, and 81% had no hypertension. Diabetes [adjusted relative risk (aRR) 2.44, 95% confidence interval (95% CI) 1.42-4.21] and first/second trimester CD4 + cell count less than 200 cells/μl (aRR 1.99, 95% CI 1.21-3.27) were associated with a greater risk of new-onset HDP. Risk of new-onset HDP was similar by antiretroviral class, but those initiating ART after 20 weeks' gestation had a greater risk (aRR 1.93, 95% CI 1.12-3.30) compared with those receiving ART at conception. CONCLUSION In this large, diverse cohort of pregnant PWH, worse early pregnancy immune status and later ART initiation were associated with an increased risk of HDP while ART class was not.

Abstract
OBJECTIVE Hypertensive disorders of pregnancy are associated with a long-term risk for cardiovascular disease among parous patients later in life. However, relatively little is known about whether hypertensive disorders of pregnancy are associated with an increased risk for ischemic stroke or hemorrhagic stroke in later life. This systematic review aimed to synthesize the available literature on the association between hypertensive disorders of pregnancy and the long-term risk for maternal stroke. DATA SOURCES PubMed, Web of Science, and CINAHL were searched from inception to December 19, 2022. STUDY ELIGIBILITY CRITERIA Studies were only included if the following criteria were met: case-control or cohort studies that were conducted with human participants, were available in English, and that measured the exposure of a history of hypertensive disorders of pregnancy (preeclampsia, gestational hypertension, chronic hypertension, or superimposed preeclampsia) and the outcome of maternal ischemic stroke or hemorrhagic stroke. METHODS Three reviewers extracted the data and appraised the study quality following the Meta-analyses of Observational Studies in Epidemiology guidelines and using the Newcastle-Ottawa scale for risk of bias assessment. RESULTS The primary outcome was any stroke (undifferentiated) and secondary outcomes included ischemic stroke and hemorrhagic stroke. The protocol for this systematic review was registered in the International Prospective Register of Systematic Reviews under identifier CRD42021254660. Of 24 studies included (10,632,808 study participants), 8 studies examined more than 1 outcome of interest. Hypertensive disorders of pregnancy were significantly associated with any stroke (adjusted risk ratio, 1.74; 95% confidence interval, 1.45-2.10). Preeclampsia was significantly associated with any stroke (adjusted risk ratio, 1.75; 95% confidence interval, 1.56-1.97), ischemic stroke (adjusted risk ratio, 1.74; 95% confidence interval, 1.46-2.06), and hemorrhagic stroke (adjusted risk ratio, 2.77; 95% confidence interval, 2.04-3.75). Gestational hypertension was significantly associated with any stroke (adjusted risk ratio, 1.23; 95% confidence interval, 1.20-1.26), ischemic stroke (adjusted risk ratio, 1.35; 95% confidence interval, 1.19-1.53), and hemorrhagic stroke (adjusted risk ratio, 2.66; 95% confidence interval, 1.02-6.98). Chronic hypertension was associated with ischemic stroke (adjusted risk ratio, 1.49; 95% confidence interval, 1.01-2.19). CONCLUSION In this meta-analysis, exposure to hypertensive disorders of pregnancy, including preeclampsia and gestational hypertension, seems to be associated with an increased risk for any stroke and ischemic stroke among parous patients in later life. Preventive interventions may be warranted for patients who experience hypertensive disorders of pregnancy to reduce their long-term risk for stroke.

BACKGROUND The postpartum period represents an opportunity to assess the cardiovascular health of women who experience chronic hypertension or hypertensive disorders of pregnancy. OBJECTIVE This study aimed to determine whether women with chronic hypertension or hypertensive disorders of pregnancy access outpatient postpartum care more quickly compared to women with no hypertension. STUDY DESIGN We used data from the Merative MarketScan Commercial Claims and Encounters Database. We included 275,937 commercially insured women aged 12 to 55 years who had a live birth or stillbirth delivery hospitalization between 2017 and 2018 and continuous insurance enrollment from 3 months before the estimated start of pregnancy to 6 months after delivery discharge. Using the International Classification of Diseases Tenth Revision Clinical Modification codes, we identified hypertensive disorders of pregnancy from inpatient or outpatient claims from 20 weeks gestation through delivery hospitalization and identified chronic hypertension from inpatient or outpatient claims from the beginning of the continuous enrollment period through delivery hospitalization. Distributions of time-to-event survival curves (time-to-first outpatient postpartum visit with a women's health provider, primary care provider, or cardiology provider) were compared between the hypertension types using Kaplan-Meier estimators and log rank tests. We used Cox proportional hazards models to estimate adjusted hazard ratios and 95% confidence intervals. Time points of interest (3, 6, and 12 weeks) were evaluated per clinical postpartum care guidelines. RESULTS Among commercially insured women, the prevalences of hypertensive disorders of pregnancy, chronic hypertension, and no documented hypertension were 11.7%, 3.4%, and 84.8%, respectively. The proportions of women with a visit within 3 weeks of delivery discharge were 28.5%, 26.4%, and 16.0% for hypertensive disorders of pregnancy, chronic, and no documented hypertension, respectively; by 12 weeks, the proportions increased to 62.4%, 64.5%, and 54.2%, respectively. Kaplan-Meier analyses indicated significant differences in utilization by hypertension type and interaction between hypertension type, and time before and after 6 weeks. In adjusted Cox proportional hazards models, the utilization rate before 6 weeks among women with hypertensive disorders of pregnancy was 1.42 times the rate for women with no documented hypertension (adjusted hazard ratio, 1.42; 95% confidence interval, 1.39-1.45). Women with chronic hypertension also had higher utilization rates compared to women with no documented hypertension before 6 weeks (adjusted hazard ratio, 1.28; 95% confidence interval, 1.24-1.33). Only chronic hypertension was significantly associated with utilization compared to the no documented hypertension group after 6 weeks (adjusted hazard ratio, 1.09; 95% confidence interval, 1.03-1.14). CONCLUSION In the 6 weeks following delivery discharge, women with hypertensive disorders of pregnancy and chronic hypertension attended outpatient postpartum care visits sooner than women with no documented hypertension. However, after 6 weeks this difference extended only to women with chronic hypertension. Overall, postpartum care utilization remained around 50% to 60% by 12 weeks in all groups. Addressing barriers to postpartum care attendance can ensure timely care for women at high risk for cardiovascular disease.

Abstract
BACKGROUND Patient-performed blood pressure monitoring in pregnancy is rarely performed in low- and middle-income country settings, including Ghana. The clinical efficacy of home blood pressure monitoring relies on a pregnant patient being able to independently execute the correct steps to position and use a blood pressure monitor and to achieve accurate blood pressure measurements. OBJECTIVE This study aimed to (1) assess whether pregnant women can correctly use an automatic blood pressure monitor to check their blood pressure before and after a brief training and (2) determine whether blood pressure values measured by pregnant women using an automatic monitor are similar to values measured by a healthcare provider using a standard clinic monitor. STUDY DESIGN This was a cross-sectional study conducted at the Korle Bu Teaching Hospital, a tertiary hospital in Accra, Ghana. Participants were adult pregnant women presenting for their first prenatal care visit. Data collection was performed by 2 Ghanaian physicians. Information on demographics, obstetrical history, and past medical history was collected. A brief training was provided on the correct use of the blood pressure monitor, including a verbal script, annotated photographs, and a hands-on demonstration. Pre- and posttraining assessments using a 9-item checklist of correct preparation, position, and use of an automatic blood pressure monitor were performed. Following a modified British Hypertension Society protocol, a series of 4 blood pressure measurements were taken, alternating between provider performed using a clinic monitor and patient performed using an automatic monitor intended for individual use and validated in pregnancy. RESULTS Among 176 participants, the mean age was 31.5 years (±5.6), and 130 (73.9%) were multiparous. Regarding socioeconomic characteristics, 128 (72.7%) were married, 171 (97.2%) had public insurance, and 87 (49.7%) had completed ≤9 years of formal education. Regarding clinical blood pressure issues, 19 (10.9%) had a history of a hypertensive disorder in a previous pregnancy, and 6 (3.4%) had chronic hypertension. Before receiving any training, 21 participants (12.1%) performed all 9 steps correctly to prepare, position, and use the automatic blood pressure monitor. Comparing pretraining vs posttraining ability, statistically significant increases were seen in the correct performance of each step and the mean number of steps performed correctly (6.1±1.8 vs 9.0±0.2, respectively; P<.001) and proportion performing all 9 steps correctly (12.1% vs 96.6%, respectively; P<.001). The mean difference between doctor-performed and patient-performed blood pressure measurements was 5.6±4.8 mm Hg for systolic blood pressure values and 3.4±3.08 mm Hg for diastolic blood pressure values, with most differences within 5 mm Hg for both systolic blood pressure values (102/176 [58.0%]) and diastolic blood pressure values (141/176 [80.1%]). CONCLUSION After a brief training, pregnant women in Ghana demonstrated that they are able to use an automatic blood pressure monitor to check their blood pressure correctly and accurately.

Abstract
Women with a history of preeclampsia (PE) have a greater risk of pulmonary arterial hypertension (PAH). In turn, pregnancy at high altitude is a risk factor for PE. However, whether women who develop PE during highland pregnancy are at risk of PAH before and after birth has not been investigated. We tested the hypothesis that during highland pregnancy, women who develop PE are at greater risk of PAH compared to women undergoing healthy highland pregnancies. The study was on 140 women in La Paz, Bolivia (3640m). Women undergoing healthy highland pregnancy were controls (C, n = 70; 29 ± 3.3 years old, mean±SD). Women diagnosed with PE were the experimental group (PE, n = 70, 31 ± 2 years old). Conventional (B- and M-mode, PW Doppler) and modern (pulsed wave tissue Doppler imaging) ultrasound were applied for cardiovascular íííassessment. Spirometry determined maternal lung function. Assessments occurred at 35 ± 4 weeks of pregnancy and 6 ± 0.3 weeks after birth. Relative to highland controls, highland PE women had enlarged right ventricular (RV) and right atrial chamber sizes, greater pulmonary artery dimensions and increased estimated RV contractility, pulmonary artery pressure and pulmonary vascular resistance. Highland PE women had lower values for peripheral oxygen saturation, forced expiratory flow and the bronchial permeability index. Differences remained 6 weeks after birth. Therefore, women who develop PE at high altitude are at greater risk of PAH before and long after birth. Hence, women with a history of PE at high altitude have an increased cardiovascular risk that transcends the systemic circulation to include the pulmonary vascular bed.

Abstract
BACKGROUND Hypertensive disorders of pregnancy (HDPs) are responsible for most perinatal and fetal mortality. Few programs are patient-centered during pregnancy, thereby increasing the risks of misinformation and misconceptions among pregnant women and, as a result, malpractices. OBJECTIVE This study aims to develop and validate a form to assess the knowledge and attitudes of pregnant women about HDPs. STUDY DESIGN A cross-sectional pilot study was conducted over 4 months, targeting 135 pregnant women from 5 obstetrics and gynecology clinics. A self-reported survey was developed and validated, and an awareness score was generated. RESULTS The mean maternal age of the participants was 27.3 (5.3) years. About 80% of the participants reported that they monitored their weight during pregnancy, and 70.4% monitored their blood pressure, out of which 73.8% performed it at the doctor's clinic only. Overall, participants had a total score of 16.9 (3.1) over 25 with higher attitude scores than knowledge scores. Less than half of the patients (45.2%) knew the cut-off for hypertension. With respect to knowledge statements, higher scores were noted for statements related to the symptoms of HDPs, and lower scores were reported for statements related to some HDP complications. Older women and those who monitored their blood pressure during pregnancy had significantly higher awareness scores. Those working had higher awareness of HDPs (67.4%), whereas about half of nonworkers (53.9%) showed lower awareness scores (P=.019). CONCLUSION Pregnant women had moderate awareness of HDPs. The short 25-item tool developed in the present study can be used in obstetric clinics to explore the awareness of women of HDPs.

Abstract
BACKGROUND COVID-19 caused a rapid integration of telehealth into prenatal care. This raises questions about the ability to screen for hypertensive disorders of pregnancy when caring for patients remotely. OBJECTIVE This study aimed to assess the effect of telehealth adaptation on the timing and severity of diagnosis of hypertensive disorders of pregnancy. STUDY DESIGN This was a retrospective study of patients with hypertensive disorders of pregnancy who delivered from April 2019 to October 2019 (before the pandemic) and April 2020 to October 2020 (during the pandemic) at 1 urban tertiary care center. The primary outcome was mean gestational age at diagnosis of a hypertensive disorder of pregnancy. The secondary outcomes included severity of diagnosis, both initially and at the time of delivery. The results were adjusted for baseline characteristic difference at P<.10, using multivariable logistic regression and analysis of covariance, as appropriate. The sample size was calculated based on a previous cohort study of patients who developed preeclampsia, with a mean gestational age at delivery of 36.3 weeks and a standard deviation of 2.8 weeks. A sample size of 124 patients would be needed per group to detect a gestational age difference of 1 week with 80% power and a 95% confidence interval. RESULTS Overall, 498 patients were included, with 231 from 2019 and 267 from 2020. Of note, 17.1% of patients had preeclampsia with severe features initially, and 29.3% of patients met the criteria at delivery. In 2020, 80.5% of patients used telehealth (vs 0.9% of patients in 2019), doing so for a mean of 29.0% of prenatal appointments. Unadjusted and adjusted analyses showed no significant difference in gestational age at diagnosis or diagnosis severity between cohorts. In the adjusted analysis, cohort year was not significantly associated with severity of initial diagnosis (adjusted odds ratio, 0.86; 95% confidence interval, 0.53-1.39; P=.53) or severity of diagnosis at delivery (adjusted odds ratio, 0.97; 95% confidence interval, 0.64-1.46; P=.87). However, Black race was significantly associated with increased risk of having severe preeclampsia at initial diagnosis (adjusted odds ratio, 1.70; 95% confidence interval, 1.01-2.85; P=.046). In addition, Black race (adjusted odds ratio, 2.62; 95% confidence interval, 1.60-4.28; P<.001), Hispanic ethnicity (adjusted odds ratio for non-Hispanic, 0.40; 95% confidence interval, 0.19-0.82; P=.01), and initial body mass index (adjusted odds ratio, 1.04; 95% confidence interval, 1.01-1.06; P=.005) were significantly associated with a diagnosis of severe preeclampsia at delivery. CONCLUSION The adaptation of telehealth was not associated with delays in the diagnosis of hypertensive disorders of pregnancy or with increased severity of diagnoses.

Abstract
BACKGROUND Eclampsia is an indicator of severe maternal morbidity and can be prevented through increased prenatal care access and early prenatal care utilization. The 2014 Medicaid expansion under the Patient Protection and Affordable Care Act allowed states to expand Medicaid coverage to nonelderly adults with incomes up to 138% of the federal poverty level. Its implementation has led to a significant increase in prenatal care access and utilization. OBJECTIVE This study aimed to assess the association of Medicaid expansion under the Affordable Care Act with eclampsia incidence. STUDY DESIGN This natural experiment study was based on US birth certificate data from January 2010 to December 2018 in 16 states that expanded Medicaid in January 2014 and in 13 states that did not expand Medicaid during the study period. The outcome was eclampsia incidence, the intervention was the implementation of the Medicaid expansion, and the exposure was state expansion status. Using the interrupted time series method, we compared temporal trends in the incidence of eclampsia before and after the intervention in expansion vs non-expansion states with adjustments for patient and hospital county characteristics. RESULTS Of the 21,570,021 birth certificates analyzed, 11,433,862 (53.0%) were in expansion states and 12,035,159 (55.8%) were in the postintervention period. The diagnosis of eclampsia was recorded in 42,677 birth certificates or 19.8 per 10,000 (95% confidence interval, 19.6-20.0). The incidence of eclampsia was higher for Black people (29.1 per 10,000) than for White (20.7 per 10,000), Hispanic (15.3 per 10,000), and birthing people of other race and ethnicity (15.4 per 10,000). In the expansion states, the incidence of eclampsia increased during the preintervention period and decreased during the postintervention period; in the nonexpansion states, a reverse pattern was observed. A statistically significant difference was observed between expansion and nonexpansion states in temporal trends between the pre- and postintervention periods, with an overall 1.6% decrease (95% confidence interval, 1.3-1.9) in the incidence of eclampsia in expansion states compared with nonexpansion states. The results were consistent in subgroup analyses according to maternal race and ethnicity, education level (less than high school or high school and higher), parity (nulliparous or parous), delivery mode (vaginal or cesarean delivery), and poverty in the residence county (high or low). CONCLUSION Implementation of the Affordable Care Act Medicaid expansion was associated with a small statistically significant reduction in the incidence of eclampsia. Its clinical significance and cost-effectiveness remain to be determined.

Abstract
OBJECTIVE To evaluate the fetal and maternal effects of the severe acute respiratory syndrome virus 2 (SARS-CoV-2) infection in women with hypertensive disorders of pregnancy. METHODS Patients with hypertensive disorders of pregnancy and SARS-CoV-2 polymerase chain reaction (PCR) positivity (n = 55) were compared with cases with similar characteristics and PCR negativity (n = 53). The study group was further divided into two groups as severe (n = 11) and nonsevere (n = 44) coronavirus disease 2019 (COVID-19). The groups were compared in terms of clinical characteristics and perinatal outcomes. RESULTS The study and control groups were similar in terms of maternal age, parity, gestational age at diagnosis, type of hypertensive disorders, magnesium sulfate administration rate, gestational age at birth, birth weight, Apgar scores, and maternal complications. However, all cases of fetal loss (n = 6) were observed in the SARS-CoV-2 positive group (p = 0.027). From the 6 cases, there were 5 in the nonsevere group and 1 patient in the severe SARS-CoV-2 positive group. Moreover, higher rates of maternal complications, lower oxygen saturation values, and intensive care unit admissions were observed in the severe COVID-19 group. CONCLUSION Physicians should be cautious about the management of hypertensive disorders of pregnancy cases with SARS-CoV-2 positivity. Fetal loss seems to be more common in cases with SARS-CoV-2 positivity and severe COVID-19 seems to be associated with higher rates of maternal complications. Close follow-up for fetal wellbeing and active management of severe cases in terms of maternal complications seem to be favorable.

Abstract
Hypertensive disorders of pregnancy (HDP) complicate 5-10% of pregnancies, with resultant lifelong increased risks of cardiovascular disease (CVD). We aimed to describe lifestyle behaviours at 6 months post-HDP in four HDP subgroups, and their association with markers of cardiometabolic health. Subgroups were chronic hypertension (CH), gestational hypertension (GH), preeclampsia, and preeclampsia superimposed on chronic hypertension (CH + PE). The BP2 study is a multi-site, three-arm, randomised controlled trial. At 6 months postpartum, the NSW Population Health Survey and BP2 surveys collected lifestyle behaviours and demographic data. Body mass index (BMI), waist circumference, and blood pressure (BP) were also assessed. Descriptive statistics, ANOVA and Spearman's correlation coefficients were used. Of 484 women (16% CH, 23% GH, 55% preeclampsia, and 6% CH + PE), 62% were overweight or obese. Only 6% met the recommended five vegetable and two fruit serves per day, and 43% did not meet the recommended 150 min of moderate-vigorous physical activity in five sessions per week. Adherence to both diet and physical activity recommendations was correlated with more favourable cardiometabolic outcomes, including lower BMI, waist circumference, and systolic and diastolic BP. Lifestyle interventions that improve diet and physical activity post-HDP are needed to reduce BP, BMI, and long-term CVD in this high-risk population.

Abstract
Hypertensive disorders of pregnancy (HDP) are rising in prevalence and associated with adverse maternal and infant health outcomes. Current guidelines recommend labetalol, nifedipine, and methyldopa as acceptable first-line agents to treat HDP in outpatient settings. However, the current practice regarding antihypertensive medication usage and selection remain unclear. A retrospective, observational cohort study was conducted in 1,641 patients with a physician diagnosis of HDP who delivered at two academic medical centers in North Carolina from 2014 to 2017. Use of any antihypertensive medication, and the agent selected, at any encounter during pregnancy or on the delivery date was collected from the electronic health record. Proportions were compared across HDP diagnosis (eclampsia/severe preeclampsia, chronic hypertension with superimposed preeclampsia, preeclampsia, gestational hypertension) by Chi-square tests and multivariable logistic regression. Antihypertensive medications were used in 1,276 (77.8%) patients overall. Among treated patients, labetalol (74.9%) was the most frequently used medication followed by nifedipine (29.6%) and hydralazine (20.5%). Methyldopa was used infrequently (4.4%). HDP type was the strongest factor associated with use of an antihypertensive agent. Relative to gestational hypertension, antihypertensive use was significantly more likely [odds ratio (95% CI)] in patients with severe preeclampsia [5.94 (3.85-9.16)], chronic hypertension with superimposed preeclampsia [4.99 (3.46-7.19)], and preeclampsia [2.13 (1.61-2.82)]. In a real-world setting, antihypertensive medication use among HDP patients was common, labetalol, nifedipine, and hydralazine were the most commonly selected agents, and increasing HDP severity was associated with a higher likelihood of antihypertensive use. Future studies comparing medication effectiveness in pregnant patients with distinct HDP diagnoses are needed.

Abstract
BACKGROUND Preeclampsia is an obstetrical disorder, which complicates 3% to 6% of pregnancies and contributes to 21.6% of readmissions in the postpartum period. The optimal strategy for inpatient monitoring of blood pressures to minimize readmissions for postpartum patients with hypertensive disorders is not known. We hypothesized that extended monitoring of postpartum patients with hypertensive disorders of pregnancy for at least 36 hours after the last blood pressure that was ≥150/100 mm Hg would result in decreased readmission rates for preeclampsia with severe features compared with those who were not observed by these blood pressure goals. OBJECTIVE This study aimed to evaluate whether extended inpatient monitoring of postpartum patients with hypertensive disorders of pregnancy for at least 36 hours after their last blood pressure that was ≥150/100 mm Hg would improve readmission rates for preeclampsia with severe features within 6 weeks of delivery. STUDY DESIGN This was a retrospective cohort study in patients with a singleton pregnancy and a diagnosis of a hypertensive disorder of pregnancy at their delivery admission or at any point during pregnancy who delivered 1 year before and 1 year after the implementation of extended inpatient monitoring of postpartum hypertension. The primary outcome was readmission for preeclampsia with severe features within 6 weeks of delivery. The secondary outcomes were length of stay during first admission, number of readmissions for any indication, intensive care unit admission, postpartum day at readmission, median systolic blood pressure in the 24-hour period before discharge, median diastolic blood pressure in the 24-hour period before discharge, intravenous antihypertensive medication required during first admission, and intravenous antihypertensive medication required during second admission. Univariable analysis was performed for the association between baseline maternal characteristics and the primary outcome. Multivariable analysis was performed, adjusting for baseline maternal characteristic differences between exposure groups. RESULTS A total of 567 patients met the inclusion criteria of which 248 patients delivered before and 319 delivered after the implementation of extended monitoring. For baseline characteristics, the extended monitoring group had a significantly higher proportion of patients who were non-Hispanic Black and Hispanic, more diagnoses of hypertensive disorders and/or diabetes mellitus at the time of admission for delivery, a difference in the distribution of hypertensive diagnoses at the time of discharge from the first admission, and fewer discharged patients from their first admission on labetalol than the preintervention group. In a univariable analysis of the primary outcome, there was a significantly increased risk of readmission for preeclampsia with severe features in the extended monitoring group (62.5% vs 96.2% of total readmissions; P=.004). In multivariable analysis, patients in the extended monitoring group were more likely to be readmitted for preeclampsia with severe features than patients in the preintervention group (adjusted odds ratio, 3.45; 95% confidence interval, 1.03-11.5; P=.044). CONCLUSION Extended monitoring with a strict blood pressure goal of <150/<100 mm Hg did not decrease readmissions for preeclampsia with severe features in patients with a previous diagnosis of a hypertensive disorder of pregnancy.

Abstract
OBJECTIVE Many studies have reported the association between platelets and preeclampsia. However, sample sizes were small, and their findings were inconsistent. We conducted a systematic review and meta-analysis to evaluate the association in pooled samples and in detail. DATA SOURCES A systematic literature search was performed using Medline, Embase, ScienceDirect, Web of Science, Cochrane Library, NICHD-DASH, LILACS, and Scopus from inception to April 22, 2022. STUDY ELIGIBILITY CRITERIA Observational studies comparing platelet count between women with preeclampsia and normotensive pregnant women were included. METHODS The mean differences with 95% confidence interval in platelet count were calculated. Heterogeneity was assessed using I2 statistics. Sensitivity and subgroup analyses were conducted. Statistical analysis was performed using RevMan 5.3 and ProMeta 3 software. RESULTS A total of 56 studies comprising 4892 preeclamptic and 9947 normotensive pregnant women were included. Meta-analysis showed that platelet count was significantly lower in women with preeclampsia than in normotensive controls (overall: mean difference, -32.83; 95% confidence interval, -40.13 to -25.52; P<.00001; I2=92%; mild preeclampsia: mean difference, -18.65; 95% confidence interval, -27.17 to -10.14; P<.00001; I2=84%; severe preeclampsia: mean difference, -42.61; 95% confidence interval, -57.53 to -27.68; P<.00001; I2=94%). Significantly lower platelet count was also observed in the second trimester (mean difference, -28.84; 95% confidence interval, -44.59 to -13.08; P=.0003; I2=93%), third trimester (mean difference, -40.67; 95% confidence interval, -52.14 to -29.20; P<.00001; I2=92%), and before the diagnosis of preeclampsia (mean difference, -18.81; 95% confidence interval, -29.98 to -7.64; P=.009; I2=87%), but not in the first trimester (mean difference, -15.14; 95% confidence interval, -37.71 to 7.43; P=.19; I2=71%). Overall, the pooled sensitivity and specificity of platelet count were 0.71 and 0.77, respectively. The area under the curve was 0.80. CONCLUSION This meta-analysis confirmed that platelet count was significantly lower in preeclamptic women, irrespective of severity and presence or absence of associated complications, even before the onset of preeclampsia and in the second trimester of pregnancy. Our findings suggest that platelet count may be a potential marker to identify and predict preeclampsia.

Abstract
Objective: The aim of this study is to estimate the risk of a new mental health diagnosis within the first 24 months postpartum among women with common pregnancy conditions, overall and by rurality. Materials and Methods: This longitudinal population-based study used the Maine Health Data Organization's All-Payer Claims Data to estimate the cumulative risk of a new mental health disorder diagnosis in the first 24 months postpartum among women with deliveries during 2007-2019 and who did not have a mental health diagnosis before pregnancy. Cox models were used to estimate hazard ratios for common pregnancy conditions (prenatal depression, gestational diabetes [GDM], and hypertensive disorders of pregnancy [HDP]) on the new diagnosis of five mental health conditions, separately. Models were adjusted for maternal demographics and pregnancy characteristics. Results: Of the 123,125 deliveries, the cumulative risk of being diagnosed in the first 24 months postpartum with depression was 28%, anxiety 25%, bipolar disorder 3%, post-traumatic stress disorder 6%, and schizophrenia/psychotic disorder 1%. Women with prenatal depression were at higher risk of having a postpartum mental health diagnosis compared with women without prenatal depression (adjusted hazard ratios [aHRs] ranged from 2.5 [for anxiety] to 4.1 [for postpartum depression]). Risk of having postpartum depression was modestly higher among women with HDP, as was the risk of postpartum bipolar disorder among those with GDM. Findings were generally similar between women living in rural versus urban areas. Conclusions: Effective interventions to prevent, screen, and treat mental health conditions among women with pregnancy complications for an extended time postpartum are warranted.

Abstract
BACKGROUND Masked hypertension has been described in nonpregnant populations as elevated blood pressure in the home setting that is not reproduced on clinical assessment. Patients with masked hypertension have a greater risk of cardiovascular morbidity than patients who have blood pressures within normal range or those with white coat hypertension. OBJECTIVE This study aimed to determine whether masked pregnancy-associated hypertension detected on Connected Maternity Online Monitoring, a remote home blood pressure monitoring system, is associated with higher rates of hypertensive disorders of pregnancy during delivery admission and maternal and neonatal morbidities. STUDY DESIGN This was a retrospective cohort study of all patients on Connected Maternity Online Monitoring who delivered at 6 hospitals in a single healthcare system between October 2016 and December 2020. Patients were classified as having either normal blood pressure or masked pregnancy-associated hypertension. Masked pregnancy-associated hypertension was defined as remotely detected systolic blood pressure of ≥140 mm Hg or diastolic blood pressure of ≥90 mm Hg after 20 weeks of gestation on 2 occasions before diagnosis in a clinical setting. The chi-square test and Student t test were used for demographic and outcomes comparisons. Logistic regression was used to adjust outcomes by race, insurance, and body mass index. RESULTS A total of 2430 deliveries were included in our analysis, including 165 deliveries that met the criteria for masked pregnancy-associated hypertension. Clinically established pregnancy-associated hypertension, defined at the time of delivery, was more common in the masked pregnancy-associated hypertension group than in the normotensive group (66% vs 10%; adjusted odds ratio, 17.2; 95% confidence interval, 11.91-24.81). Patients with masked pregnancy-associated hypertension had higher rates of preeclampsia with severe features on delivery admission than normotensive patients (28% vs 2%; adjusted odds ratio, 23.35; 95% confidence interval, 14.25-38.26). Preterm delivery (16% vs 7%; adjusted odds ratio, 2.47; 95% confidence interval, 1.55-3.94), cesarean delivery(38% vs 26%; adjusted odds ratio, 1.58; 95% confidence interval, 1.13-2.23), small for gestational age (11% vs 5%; adjusted odds ratio, 2.27; 95% confidence interval, 1.31-3.94), and neonatal intensive care unit admission (8% vs 4%; adjusted odds ratio, 2.20; 95% confidence interval, 1.18-4.09) were more common among patients with masked pregnancy-associated hypertension than among normotensive patients. CONCLUSION With more outcomes research, remote blood pressure monitoring may prove to be an important tool in identifying pregnancies at risk of complications related to masked hypertension.

Abstract
In the recent decades, endothelial dysfunction (ED) has been recognized as a significant contributing factor in the pathogenesis of many pathological conditions. In interaction with atherosclerosis, hypercholesterolemia, and hypertension, ED plays a crucial role in the pathogenesis of coronary artery disease, chronic renal disease, and microvascular complications in diabetes mellitus. Although ED plays a significant role in the pathogenesis of several pregnancy-related disorders such as preeclampsia, HELLP syndrome, fetal growth restriction, and gestational diabetes mellitus, the exact pathogenetic mechanisms are still a matter of debate. The increased prevalence of these entities in patients with preexisting vascular diseases highlights the essential pathological role of the preexisting ED in these patients. The abnormal uteroplacental circulation and the release of soluble factors from the ischemic placenta into the maternal bloodstream are the main causes of the maternal ED underlying the characteristic preeclamptic phenotype. Besides the increased risk for maternal and fetal poor outcomes, the preexisting ED also increases the risk of development of future cardiovascular diseases in these patients. This study aimed to look deeper into the role of ED in the pathogenesis of several pregnancy-related hypertensive and liver diseases. Hopefully, it could contribute to improvement of the awareness, knowledge, and management of these conditions and also to the reduction of the adverse outcomes and additional long-term cardiovascular complications.

Abstract
BACKGROUND Adverse pregnancy outcomes (APOs), hypertensive disorders of pregnancy, gestational diabetes mellitus, and preterm birth are associated with ischemic heart disease in later life. OBJECTIVES The authors aimed to study the features of premature myocardial infarction (MI) among women with and without prior APOs. METHODS We performed a retrospective analysis of women with premature MI (<65 years of age) referred for left heart catheterization matched with a database of abstracted pregnancy data. We compared MI characteristics and epicardial coronary anatomy between women with and without APOs during their index pregnancy and evaluated time from delivery to MI. RESULTS Of 391 women with premature MI and associated coronary angiography (age: 49 ± 8 years), 154 (39%) had a prior APO (hypertensive disorders of pregnancy n = 78, preeclampsia n = 35, gestational diabetes mellitus n = 28, and preterm birth n = 48). Women with APO history had a higher prevalence of diabetes (33% vs 16% without APO; P = 0.001) and presented earlier with MI following delivery (19.6 [IQR: 14.3-23.5] years vs those without APO 21.5 [IQR: 17.0-25.4] years; P = 0.012), driven by preeclampsia (17.1 [IQR: 12.7-22.4] years, P = 0.010). Women with and without APOs had similar MI features including rates of ST-segment elevation MI, obstructive and multi-vessel coronary artery disease, percutaneous coronary intervention, and shock. CONCLUSIONS Among women with premature MIs, 39% had a history of an APO. Women with APO history presented sooner after pregnancy but had similar MI characteristics vs those without APOs. Pregnancy history may identify women who warrant early, aggressive cardiovascular disease prevention.

Abstract
Anti-β2-glycoprotein I/HLA-DR (anti-β2GPI/HLA-DR) antibody has been reported to be associated with antiphospholipid syndrome and recurrent pregnancy loss (RPL). We conducted a prospective multicenter cross-sectional study aimed at evaluating whether the anti-β2GPI/HLA-DR antibody is associated with adverse obstetric outcomes and RPL. From 2019 to 2021, serum anti-β2GPI/HLA-DR antibody levels (normal, <73.3 U) were measured in 462 women with RPL, 124 with fetal growth restriction (FGR), 138 with hypertensive disorders of pregnancy (HDP), 71 with preterm delivery before 34 gestational weeks (preterm delivery (PD) ≤ 34 GWs), and 488 control women who experienced normal delivery, by flow cytometry analysis. The adjusted odds ratios (aORs) of anti-β2GPI/HLA-DR antibody positivity for adverse obstetric outcomes and RPL were evaluated on the basis of comparisons between the control and each patient group, using multivariable logistic regression analysis. The following were the positivity rates for the anti-β2GPI/HLA-DR antibody in the patient and control groups: RPL, 16.9%; FGR, 15.3%; HDP, 17.4%; PD ≤ 34 GWs, 11.3%; and the control, 5.5%. It was demonstrated that anti-β2GPI/HLA-DR antibody positivity was a significant risk factor for RPL (aOR, 3.3 [95% confidence interval {CI} 1.9-5.6], p < 0.001), FGR (2.7 [1.3-5.3], p < 0.01), and HDP (2.7 [1.4-5.3], p < 0.01) although not for PD ≤ 34 GWs. For the first time, our study demonstrated that the anti-β2GPI/HLA-DR antibody is involved in the pathophysiology underlying FGR and HDP, as well as RPL.

Abstract
The relationship between weight gain during pregnancy and the onset of hypertensive disorders of pregnancy in women with pre-pregnancy obesity remains unclear. We examined the effects of weight gain during pregnancy on hypertensive disorders of pregnancy among women with pre-pregnancy body mass index (BMI) ≥ 25.0 kg/m2. This multicenter retrospective cohort study included nullipara women who delivered at two units in Japan between 1 January 2013, and 31 December 2020. Singleton primipara (n = 3040) were categorized into two pre-pregnancy BMI groups: 25.0-<30.0, and ≥30.0 kg/m2. Using multiple logistic regression analyses (reported as adjusted odds ratio and 95% confidence interval), gestational weight gain effects on overall hypertensive disorders of pregnancy, gestational hypertension, and pre-eclampsia were determined. Gestational weight gain increased hypertensive disorders of pregnancy (1.09, 1.03-1.16, p < 0.05) and pre-eclampsia risk (1.10, 1.01-1.20, p < 0.05) among the BMI 25.0-<30.0 kg/m2 group and hypertensive disorders of pregnancy risk among the ≥30.0 kg/m2 group (1.07, 1.00-1.05, p < 0.05). Using receiver operating characteristic curve analyses, among the BMI 25.0-<30.0 kg/m2 group, for hypertensive disorders of pregnancy (area under the curve [AUC], 0.63, p < 0.05) and pre-eclampsia (AUC, 0.62; p < 0.05), the weight gain cut-off was 10.5 and 10.6 kg, with sensitivity/specificity of 0.47/0.73 and 0.50/0.73, respectively. For the BMI ≥30.0 kg/m2 group (AUC, 0.63, p < 0.05), the cut-off was 3.5 kg (sensitivity/specificity, 0.75/0.49). The optimal gestational weight gain for reducing hypertensive disorders of pregnancy among women with a pre-pregnancy BMI > 25 kg/m2 may facilitate personalized pre-conception counseling among women with obesity.

Abstract
A balanced vaginal microbiome dominated by Lactobacillus can help promote women's reproductive health, with Lactobacillus crispatus showing the most beneficial effect. However, the potential role of vaginal microbiomes in hypertensive disorders of pregnancy (HDP) development is not thoroughly explored. In this nested case-control study based on an assisted reproductive technology follow-up cohort, we prospectively assessed the association between pregestational vaginal microbiomes with HDP by collecting vaginal swabs from 75 HDP cases (HDP group) and 150 controls (NP group) and using 16S amplicon sequencing for bacterial identification. The vaginal microbial composition of the HDP group significantly differed from that of the NP group. The abundance of L. crispatus was significantly lower, and the abundances of Gardnerella vaginalis was significantly higher, in the HDP group than in the NP group. Of note, L. crispatus-dominated vaginal community state type was associated with a decreased risk for HDP (odds ratio = 0.436; 95% confidence interval, 0.229 to 0.831) compared with others. Additionally, network analysis revealed different bacterial interactions with 61 and 57 exclusive edges in the NP and HDP groups, respectively. Compared with the HDP group, the NP group showed a higher weighted degree and closeness centrality. Several taxa, including G. vaginalis, L. iners, and bacterial vaginosis-associated bacteria (Prevotella, Megasphaera, Finegoldia, and Porphyromonas), were identified as "drivers" for network rewiring. Notable alterations of predicted pathways involved in amino acid, cofactor, and vitamin metabolism; membrane transport; and bacterial toxins were observed in the HDP group. IMPORTANCE The etiology of HDP remains unclear to date. Effective methods for the individualized prediction and prevention are lacking. Pregestational vaginal dysbiosis precedes the diagnosis of HDP, providing a novel perspective on the etiology of HDP. Early pregnancy is the critical period of placental development, and abnormal placentation initiates HDP development. Thus, disease prevention should be considered before pregnancy. Vaginal microbiome characterization and probiotic interventions before pregnancy are preferred because of their safety and potential for early prevention. This study is the first to prospectively assess associations between pregestational vaginal microbiome and HDP. L. crispatus-dominated vaginal community state type is linked to a reduced risk for HDP. These findings suggest that vaginal microbiome characterization may help identify individuals at high risk for HDP and offer potential targets for the development of novel pregestational intervention methods.

Abstract
BACKGROUND The US Preventive Services Taskforce published guidelines in 2014 recommending that low-dose aspirin be initiated between 12 and 28 weeks of gestation among high-risk patients for preeclampsia prophylaxis. Moreover, low-dose aspirin is recommended by some clinicians for the prevention of preterm birth. OBJECTIVE This study aimed to evaluate whether there is an association between the US Preventive Services Taskforce aspirin guideline hypertensive disorders of pregnancy and the rates of hypertensive disorders of pregnancy and preterm birth in individuals with pregestational diabetes mellitus. STUDY DESIGN This was a repeated cross-sectional analysis of individuals with pregestational diabetes mellitus and at least 1 singleton delivery at >20 weeks of gestation with records available in the National Vital Statistics System between 2010 and 2018. The primary outcome was hypertensive disorders of pregnancy, and the secondary outcome was preterm birth. Demographics and clinical characteristics among individuals in the pre-US Preventive Services Taskforce guideline cohort (2010-2013) were compared with that of individuals in the post-US Preventive Services Taskforce guideline cohort (2015-2018). Multivariable regression estimated the odds ratios and 95% confidence intervals for the association between guideline publication and the selected endpoints. Effect modification was assessed for access to prenatal care using the Kotelchuck Index (<80% vs ≥80%). Furthermore, a sensitivity analysis limited to nulliparas was performed. RESULTS Overall, 224,065 individuals were included. Individuals in the post-US Preventive Services Taskforce guideline cohort were more likely to be older, be obese, and have a history of preterm birth. In unadjusted and adjusted modeling, delivery in the post-US Preventive Services Taskforce guideline cohort was associated with hypertensive disorders of pregnancy (adjusted odds ratio, 1.25; 95% confidence interval, 1.22-1.28) and preterm birth (adjusted odds ratio, 1.10; 95% confidence interval, 1.08-1.12). The adjusted odds ratios for hypertensive disorders of pregnancy and preterm birth were more pronounced among those with less than adequate access to care. The findings were similar in the sensitivity analysis of only nulliparas. CONCLUSION Delivery after US Preventive Services Taskforce aspirin guideline publication was associated with higher rates of hypertensive disorders of pregnancy and preterm birth in a population of individuals with diabetes mellitus. It is unknown whether patient or practitioner factors, or other changes in obstetrical care, contributed to these findings.

Abstract
Background Breastfeeding is associated with improved cardiometabolic profiles decades after pregnancy. Whether this association exists for women who experience hypertensive disorders of pregnancy (HDP) is unknown. The authors examined whether breastfeeding duration or exclusivity are associated with long-term cardiometabolic health, and whether this relationship differs by HDP status. Methods and Results Participants (N=3598) were from the UK ALSPAC (Avon Longitudinal Study of Parents and Children) cohort. HDP status was assessed by medical record review. Breastfeeding behaviors were assessed by contemporaneous questionnaires. Breastfeeding duration was categorized as never, <1, 1 to <3, 3 to <6, 6 to <9, and 9+ months. Breastfeeding exclusivity was categorized as never, <1, 1 to <3, and 3 to 6 months. Measures of cardiometabolic health (body mass index, waist circumference, C-reactive protein, insulin, proinsulin, glucose, lipids, blood pressure, mean arterial pressure, carotid intima-media thickness, and arterial distensibility) were measured 18 years after pregnancy. Analyses were conducted using linear regression adjusting for relevant covariates. Breastfeeding was associated with improved cardiometabolic health (lower body mass index, waist circumference, C-reactive protein, triglycerides, insulin, and proinsulin) in all women, but not for every breastfeeding duration. Interaction tests revealed additional benefits in women with a history of HDP, with the strongest benefit observed in the 6- to 9-month breastfeeding category (diastolic blood pressure, -4.87 mm Hg [95% CI, -7.86 to -1.88], mean arterial pressure -4.61 [95% CI, -7.45 to -1.77], and low-density lipoprotein cholesterol, -0.40 mmol/L [95% CI, -0.62 to -0.17 mmol/L]). Differences in C-reactive protein and low-density lipoprotein "survived" Bonferroni correction (P<0.001). Similar results were observed in the exclusive breastfeeding analyses. Conclusions Breastfeeding may be a mechanism to reduce the cardiovascular disease sequela associated with HDP; however, there is a need to establish whether associations reflect a causal effect.

Abstract
BACKGROUND The present study analyzed the relation of disaster exposure prior to pregnancy with maternal characteristics and obstetric outcomes. METHODS The participants were 13,148 pregnant women recruited from 2013 to 2017. The women were classified into three groups by the severity of housing damage caused by the Great East Japan Earthquake of 2011: group A, house was not destroyed/did not live in the disaster area; group B, half/part of the house was destroyed; and group C, house was totally/mostly destroyed. Maternal characteristics, hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus (GDM), and gestational weeks were obtained using questionnaires and medical records. Multiple logistic regression analyses were performed to investigate the relation between disaster exposure and maternal characteristics, HDP, and GDM. A structural equation model was applied to investigate the relation of disaster exposure with HDP and gestational weeks. RESULTS The homes of about 11% of the women were totally/mostly destroyed. For groups B and C compared with those in group A, the adjusted ORs for HDP were 1.04 and 1.26 (P for trend = 0.01), and for GDM were 0.89 and 1.14 (P for trend = 0.9), respectively. Pre-pregnancy body mass index (BMI) mediated 23.2% of the relation between disaster exposure and HDP. Disaster exposure was associated with gestational weeks. CONCLUSION Disaster exposure at least 2.5 years before pregnancy was found to be associated with maternal characteristics and the prevalence of HDP. Pre-pregnancy BMI mediated the relation between disaster exposure and the prevalence of HDP, and gestational weeks were reduced through HDP.

Abstract
Introduction Endotypes leading to very and extremely preterm birth are clustered into two groups: infection/inflammation and dysfunctional placentation. We conducted a systematic review of observational studies exploring the association between these two endotypes and the pharmacological closure of patent ductus arteriosus (PDA) induced by cyclooxygenase (COX) inhibitors. Chorioamnionitis represented the infectious-inflammatory endotype, while dysfunctional placentation proxies were hypertensive disorders of pregnancy (HDP) and small for gestational age (SGA) or intrauterine growth restriction. Methods PubMed/Medline and Embase databases were searched. The random-effects odds ratio (OR) and 95% confidence interval (CI) were calculated for each association. We included 30 studies (12,639 infants). Results Meta-analysis showed a significant association between exposure to HDP and increased rate of pharmacological closure of PDA (17 studies, OR 1.41, 95% CI 1.10-1.81, p = 0.006). In contrast, neither chorioamnionitis (13 studies, OR 0.75, 95% CI 0.47-1.18, p = 0.211) nor SGA (17 studies, OR 1.20, 95% CI 0.96-1.50, p = 0.115) were significantly associated with the response to therapy. Subgroup analyses showed that the higher response to COX inhibitors in the HDP group was significant for indomethacin (OR 1.568, 95% CI 1.147-2.141, p = 0.005) but not for ibuprofen (OR 1.107, 95% CI 0.248-4.392, p = 0.894) or for the studies using both drugs (OR 1.280, 95% CI 0.935-1.751, p = 0.124). However, meta-regression showed that this difference between the drugs was not statistically significant (p = 0.404). Discussion/Conclusion Our data suggest that the pathologic condition that triggers prematurity may alter the response to pharmacological treatment of PDA. The DA of infants exposed to HDP appears to be more responsive to COX inhibitors.

Abstract
BACKGROUND Although substantial efforts have been made to reduce the rates of adolescent pregnancy, the United States continues to have higher rates than other industrialized countries. Research and reporting usually focus on adolescents aged 15 to 19 years. Although less common, there are pregnant young adolescents that are ≤15 years of age, with developmental and social differences from older, high school-aged adolescents. OBJECTIVE Because adolescent pregnancies are of particular concern because of long-term socioeconomic consequences to parent and child, we sought to determine whether young adolescents (≤15 years old) had worse perinatal outcomes than older adolescents (16-19 years old) and older parents (≥20 to 34 years old) among those living in an urban inner city. STUDY DESIGN This was a study of pregnant individuals who delivered a singleton pregnancy without evidence of chronic hypertension or pregestational diabetes mellitus at a safety net hospital from January 2010 to May 2021. Parents were grouped by age at the time of delivery into young adolescents (≤15 years old) and older adolescents (16-19 years old). For a comparison group, nulliparous older parents aged 20 to 34 years with singleton pregnancies were analyzed for perinatal outcomes and compared with the adolescent cohorts. When analyzing baseline parental characteristics, a preponderance of obesity was noted in the young adolescent cohort. An analysis of parental characteristics and perinatal outcomes among young adolescents with obesity vs young adolescents without obesity ≤15 years old was performed. Statistical analysis included χ2 and Student t test with P values of <.05 considered significant. Logistic regression analysis was performed to control for potentially confounding demographic variables. RESULTS Overall, 10,894 adolescent women delivered, with 868 young adolescents and 10,026 older adolescents. Pairwise comparisons showed young adolescents had a different race distribution than older adolescents (P=.006) and older parents (P<.001). Young adolescents were more likely to be Hispanic or non-Hispanic Black (P<.001) and accessed prenatal care at a later gestational age (19.7±8.9 weeks) compared with older adolescents (16.7±8.6 weeks) and the comparison older cohort of parents (15.7±8.7 weeks) (P<.001) and less frequently in pregnancy (P<.001) compared with older parents. Young adolescents were more likely to have preterm birth at <37 weeks of gestation (P<.001) and eclampsia (0.5% vs 0.1%) (P=.01) than older adolescents. Therefore, low birthweights of ≤2500 g (P=.02) and neonatal intensive care unit admission (P=.048) were also increased in adolescents. When adjusted for race, ethnicity, and body mass index, preeclampsia with severe features (P<.001) and preterm birth at <37 weeks of gestation (P=.048) remained significant. Young adolescents with obesity were more likely to have preeclampsia with severe features (odds ratio, 1.81; 95% confidence interval, 1.22-2.68) and be delivered via cesarean delivery (odds ratio, 2.71; 95% confidence interval, 1.85-3.99) than adolescents without obesity. CONCLUSION In an urban inner city, young adolescent parents were more likely to be women of color, have later presentations to prenatal care, and have increased rates of preterm birth. Young adolescents had high rates of obesity, which was associated with increased rates of hypertensive disorders of pregnancy and cesarean delivery, than adolescents without obesity.

Abstract
BACKGROUND Individuals with pregnancies complicated by hypertensive disorders of pregnancy are at increased risk of cardiovascular disease. However, not all who have hypertensive disorders of pregnancy are at risk, and not all who have uncomplicated pregnancies are without risk. OBJECTIVE This study aimed to determine if use of first-degree family history of cardiovascular disease or chronic hypertension better identifies individuals who need postpartum cardiovascular risk screening. STUDY DESIGN Participants were included if they had pregnancies complicated by hypertensive disorders of pregnancy or uncomplicated, term pregnancies. Individuals with a first-degree relative with chronic hypertension, myocardial infarction, or stroke were deemed to have a positive family history and were thus included. RESULTS Four groups were considered: 302 individuals with hypertensive disorders of pregnancy who had a positive family history, 218 individuals with hypertensive disorders of pregnancy with no family history, 39 control individuals with a positive family history, and 63 control individuals with no family history. Among individuals with hypertensive disorders of pregnancy, those with a positive family history were more likely to be diagnosed with chronic hypertension, and to have elevated 30-year lipid, 30-year body mass index, and lifetime cardiovascular disease risk score (all P<.05). Among individuals with uncomplicated pregnancies, those with a positive family history were more likely to be diagnosed with chronic hypertension (P<.05) and meet criteria for metabolic syndrome (P<.05). CONCLUSION First-degree family history of cardiovascular disease and/or chronic hypertension can be used to reliably identify individuals without pregnancy complications who should have postpartum cardiovascular risk screening, and may better determine which individuals who have a pregnancy complicated by hypertensive disorders of pregnancy would most benefit from postpartum cardiovascular risk screening.

Abstract
Objectives Clinical discoveries are heralded by observing unique and unusual clinical cases. The effort of identifying such cases rests on the shoulders of busy clinicians. We assess the feasibility and applicability of an augmented intelligence framework to accelerate the rate of clinical discovery in preeclampsia and hypertensive disorders of pregnancy-an area that has seen little change in its clinical management. Methods We conducted a retrospective exploratory outlier analysis of participants enrolled in the folic acid clinical trial (FACT, N=2,301) and the Ottawa and Kingston birth cohort (OaK, N=8,085). We applied two outlier analysis methods: extreme misclassification contextual outlier and isolation forest point outlier. The extreme misclassification contextual outlier is based on a random forest predictive model for the outcome of preeclampsia in FACT and hypertensive disorder of pregnancy in OaK. We defined outliers in the extreme misclassification approach as mislabelled observations with a confidence level of more than 90%. Within the isolation forest approach, we defined outliers as observations with an average path length z score less or equal to -3, or more or equal to 3. Content experts reviewed the identified outliers and determined if they represented a potential novelty that could conceivably lead to a clinical discovery. Results In the FACT study, we identified 19 outliers using the isolation forest algorithm and 13 outliers using the random forest extreme misclassification approach. We determined that three (15.8%) and 10 (76.9%) were potential novelties, respectively. Out of 8,085 participants in the OaK study, we identified 172 outliers using the isolation forest algorithm and 98 outliers using the random forest extreme misclassification approach; four (2.3%) and 32 (32.7%), respectively, were potential novelties. Overall, the outlier analysis part of the augmented intelligence framework identified a total of 302 outliers. These were subsequently reviewed by content experts, representing the human part of the augmented intelligence framework. The clinical review determined that 49 of the 302 outliers represented potential novelties. Conclusions Augmented intelligence using extreme misclassification outlier analysis is a feasible and applicable approach for accelerating the rate of clinical discoveries. The use of an extreme misclassification contextual outlier analysis approach has resulted in a higher proportion of potential novelties than using the more traditional point outlier isolation forest approach. This finding was consistent in both the clinical trial and real-world cohort study data. Using augmented intelligence through outlier analysis has the potential to speed up the process of identifying potential clinical discoveries. This approach can be replicated across clinical disciplines and could exist within electronic medical records systems to automatically identify outliers within clinical notes to clinical experts.

Abstract
OBJECTIVE To evaluate whether routine mid-gestational uterine artery Doppler (UtAD) modifies the risk for preterm pre-eclampsia after first-trimester combined pre-eclampsia screening. DESIGN Retrospective cohort study. SETTING London Tertiary Hospital. POPULATION A cohort of 7793 women with singleton pregnancies, first-trimester pre-eclampsia screening using the Fetal Medicine Foundation (FMF) algorithm and UtAD pulsatility index (PI) assessment at the mid-gestation ultrasound. METHODS Pregnancies were divided into four groups: high risk in both trimesters (H1 H2 ), high risk in the first but not in the second trimester (H1 L2 ), low risk in the first but high risk in the second trimester (L1 H2 ) and low risk in both trimesters (L1 L2 ). MAIN OUTCOME MEASURES Small for gestational age (SGA), hypertensive disorders of pregnancy (HDP) and stillbirth. RESULTS In this cohort, 600 (7.7%) and 620 (7.9%) women were designated as being at high risk in the first and second trimesters, respectively. Preterm pre-eclampsia was more prevalent in the H1 L2 group (4.5%) than in women considered at low risk in the first trimester (0.4%, p < 0.0001). The prevalence of preterm pre-eclampsia in the L1 H2 group (3.3%) was significantly lower than that in women considered at high risk in the first trimester (7.0%, p = 0.0076), and was higher than that observed in the L1 L2 group (0.2%, p < 0.0001). The prevalence of SGA and term HDP followed similar trends. CONCLUSIONS Pre-eclampsia risk after first-trimester FMF pre-eclampsia screening may be stratified through mid-gestational routine UtAD assessment. Pregnancy care should not be de-escalated for low mid-gestational UtAD resistance in women classified as being at high risk in the first trimester. The escalation of care may be justified in women at low risk but with high mid-gestational UtAD resistance.

Abstract
OBJECTIVE To study the effects of unexpected follicular development and ovulation in artificial cycles (ACs) on pregnancy outcomes. DESIGN A retrospective cohort study. SETTING A university-affiliated fertility center. PATIENT(S) A total of 1,427 patients who underwent a single, frozen-thawed blastocyst transfer with AC regimens from January 2014 to December 2020 at a university-affiliated fertility center were included. INTERVENTION(S) Unexpected follicular development and ovulation in ACs. MAIN OUTCOME MEASURE(S) Live birth rate (LBR), biochemical pregnancy rate, clinical pregnancy rate, and ongoing pregnancy rate. RESULT(S) A total of 161 patients with unexpected follicular development and ovulation in ACs (ovulation group) and 1,266 patients without growing follicles in ACs (control group) were enrolled. The patients in the ovulation group were older and had higher levels of serum follicle-stimulating hormone and lower levels of serum antimüllerian hormone. After propensity score matching, the baseline characteristics between the 2 groups were comparable and no significant difference was observed in the LBR (ovulation group, 39.0% vs. control group, 39.0%), biochemical pregnancy rate (ovulation group, 60.3% vs. control group, 58.2%), clinical pregnancy rate (ovulation group, 53.4% vs. control group, 50.7%), or ongoing pregnancy rate (ovulation group, 42.5% vs. control group, 40.4%). Moreover, the patients in the ovulation group showed a lower risk of hypertensive disorders of pregnancy (HDP) (1.6% vs. 15.3%). A subgroup analysis of women who delivered singleton live-born babies also demonstrated that unexpected follicular development and ovulation in ACs was associated with a decreased risk of HDP (adjusted odds ratio, 0.070; 95% confidence interval, 0.007-0.712) and an increased risk of large-for-gestational-age infants (adjusted odds ratio, 4.046; 95% confidence interval, 1.319-12.414). CONCLUSION(S) Women with unexpected follicular development and ovulation during single frozen-thawed blastocyst transfer with AC regimens had a similar LBR and a reduced risk of HDP compared with those with routine AC regimens, and singleton neonates had an increased risk of being large for gestational age.

Abstract
Pregnancy-related complications are associated with a higher risk of various incident cardiovascular diseases, but their specific potential relationship with incident atrial fibrillation (AF) is less clear. This systematic review summarises the available evidence from observational studies which have examined associations between pregnancy-related complications and the risk of AF. MEDLINE and EMBASE (Ovid) were searched for studies between 1990 to 10 February 2022. Pregnancy-related complications examined included hypertensive disorders of pregnancy (HDP), gestational diabetes, placental abruption, preterm birth, small-for-gestational-age and stillbirth. Study selection, data extraction and quality assessment were completed independently by two reviewers. Narrative synthesis was used to evaluate the results of the included studies. Nine observational studies were included, with eight eligible for narrative synthesis. Sample sizes ranged from 1839 to 2,359,386. Median follow-up ranged from 2 to 36 years. Six studies reported that pregnancy-related complications were associated with a significantly increased risk of incident AF. Hazard ratios (HRs) (95% confidence intervals) for the four studies that evaluated HDP ranged from 1.1 (0.8-1.6) to 1.9 (1.4-2.7). For the four studies that evaluated pre-eclampsia, HRs ranged from 1.2 (0.9-1.6) to 1.9 (1.7-2.2). Current evidence from observational studies suggests pregnancy-related complications are associated with a significantly higher risk of incident AF. However, only a small number of studies examining each pregnancy-related complication were identified, and considerable statistical heterogeneity was observed. Further large-scale prospective studies are required to confirm the association between pregnancy-related complications and incident AF.

Abstract
OBJECTIVES We aimed to determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy is associated with an increased risk of hypertensive disorders of pregnancy (HDP). METHODS A multicenter retrospective cohort study of all pregnant patients who had SARS-CoV-2 testing and delivered in a large health system between March 2020 and March 2021. Cases were stratified into two groups: patients who tested positive for SARS-CoV-2 during pregnancy vs. patients who tested negative. The primary outcome of HDP, defined as a composite of gestational hypertension, preeclampsia, hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP Syndrome), and eclampsia by standard criteria, was compared between the two groups. Statistical analysis included multivariable logistic regression to adjust for potential confounders such as maternal demographics and comorbidities. Patient ZIP codes were linked to neighborhood-level data from the US Census Bureau's American Community Survey. RESULTS Of the 22,438 patients included, 1,653 (7.4%) tested positive for SARS-CoV-2 infection. Baseline demographics such as age, body mass index, race, ethnicity, insurance type, neighborhood-built environmental and socioeconomic status, nulliparity, and pregestational diabetes differed significantly between the two groups. SARS-CoV- 2 infection in pregnancy was not associated with an increased risk of HDP compared to those without infection (14.9 vs. 14.8%; aOR 1.06 95% CI 0.90-1.24). CONCLUSIONS In this large cohort that included a universally-tested population with several socioeconomic indicators, SARS-CoV-2 infection in pregnancy was not associated with an increased risk of HDP.

Abstract
Pregnancy is associated with alteration in the hemodynamic state. In clinical practice, only peripheral blood pressure is measured; however, central blood pressure is a better predictor of cardiovascular events. We have investigated variations in peripheral blood pressure, central blood pressure, and augmentation index in healthy non-pregnant and pregnant women. This was a cross-sectional study of 107 pregnant women (I trimester n = 19, II trimester n = 39, and III trimester n = 49) and age-matched 53 non-pregnant women (Follicular phase n = 25 and luteal phase n = 28). The augmentation index showed a significant decrease with the progression of pregnancy. Central systolic blood pressure showed a decreasing trend (non-significant) with the progression of pregnancy. Heart rate shows a significant increase from follicular to luteal phase in non-pregnant women, which further increases with the progression of pregnancy. Longitudinal studies involving larger sample sizes might provide some insights into the significance of including central blood pressure and augmentation index for routine checkups in both non-pregnant and pregnant women.

Abstract
BACKGROUND Compared with gestational hypertension, preeclampsia has traditionally been considered the worse end of the spectrum of hypertensive disorders of pregnancy. It is associated with worse pregnancy outcomes and future cardiovascular morbidities. Both hypertensive disorders may be associated with cardiac maladaptation in pregnancy. However, previous studies were limited by small numbers and a paucity of longitudinal data and unaccounted for the contribution of maternal characteristics that can affect hemodynamics. OBJECTIVE This study aimed to assess, in an unselected population, the maternal cardiac adaptation in normotensive and hypertensive pregnancies after controlling for important maternal characteristics that affect maternal cardiac function and the interaction among these covariates. STUDY DESIGN This was a prospective, multicenter longitudinal study of maternal hemodynamics, assessed by a noninvasive bioreactance technology, measured at 11 0/7 to 13 6/7, 19 0/7 to 24 0/7, 30 0/7 to 34 0/7, and 35 0/7 to 37 0/7 weeks of gestation in 3 groups of women. Group 1 was composed of women with preeclampsia (n=45), group 2 was composed of women with gestational hypertension (n=61), and group 3 was composed of normotensive women (n=1643). A multilevel linear mixed-effects model was performed to compare the repeated measures of hemodynamic variables controlling for maternal age, height, weight, weight gain, race, previous obstetrical history, and birthweight. RESULTS After adjusting for confounders that significantly affect maternal hemodynamics, both group 1 and group 2, compared with group 3, had pathologic cardiac adaptation. Group 1, compared with group 3, demonstrated hyperdynamic circulation with significantly higher cardiac output driven by greater stroke volume in the first trimester of pregnancy. As the pregnancies progressed to after 20 0/7 weeks of gestation, this hyperdynamic state transitioned to hypodynamic state with low cardiac output and high peripheral vascular resistance. Group 2, compared with group 3, had no significant differences in cardiac output, stroke volume, and heart rate before 20 0/7 weeks of gestation but thereafter demonstrated a continuous decline in cardiac output and stroke volume, similar to group 1. Both groups 1 and 2, compared with group 3, had persistently elevated mean arterial pressure and uterine artery pulsatility index throughout pregnancy. CONCLUSION After adjusting for confounders that affect maternal hemodynamics in an unselected pregnant population, women with preeclampsia and gestational hypertension, compared with normotensive women, demonstrated similar cardiac maladaptation. This pathologic profile was evident after 20 0/7 weeks of gestation and at least 10 weeks before the clinical manifestation of the disease.

Abstract
BACKGROUND Hypertensive disorders of pregnancy have been identified as a leading contributor to severe maternal morbidity and mortality. Pregnant persons with hypertensive disorders who develop severe hypertension at delivery admission have been shown to experience higher rates of severe maternal morbidity relative to those without severe hypertension. Current guidelines recommend prompt treatment of severe hypertension given known associated maternal and fetal risks; however, only 1 previous study has described an association between timeliness of antihypertensive therapy and risk of severe maternal morbidity. OBJECTIVE This study aimed to characterize how development of severe intrapartum hypertension and its timely treatment affect the risk of severe maternal morbidity. STUDY DESIGN We conducted a population cohort study of deliveries with and without hypertensive disorders of pregnancy at a single urban hospital between 2016 and 2018. Among deliveries of persons with hypertensive disorders of pregnancy, we identified those with persistent severe hypertension (defined as blood pressure ≥160/105 mm Hg sustained over ≥15 minutes) and further classified individuals with severe hypertension as having received timely (within 60 minutes) or delayed treatment. Severe maternal morbidity was identified using a composite measure developed by the Centers for Disease Control and Prevention. We calculated overall and indicator-specific rates of severe maternal morbidity for 4 categories of deliveries: without hypertensive disorder of pregnancy, with hypertensive disorder of pregnancy without severe hypertension, with severe hypertension and timely treatment, and with severe hypertension and delayed treatment. We assessed the association between hypertensive disorder of pregnancy, severe hypertension, timeliness of treatment, and severe maternal morbidity using multivariable robust Poisson regression, adjusting for demographic and clinical characteristics. RESULTS Of 3723 delivery hospitalizations within the study time frame, 32.3% (1204/3723) were complicated by presence of a hypertensive disorder without severe hypertension and 5.7% (211/3723) by presence of a hypertensive disorder with severe hypertension. Among those with severe hypertension, 48.8% (103/211) received timely treatment. Compared with deliveries not complicated by a hypertensive disorder, severe maternal morbidity risk was increased for hypertensive disorder of pregnancy without severe hypertension (124.4/1000 vs 52.0/1000; adjusted risk ratio, 1.84; 95% confidence interval, 1.41-2.40), severe hypertension with timely treatment (233.0/1000; adjusted risk ratio, 3.81; 95% confidence interval, 2.45-5.92), and severe hypertension with delayed treatment (305.6/1000; adjusted risk ratio, 5.38; 95% confidence interval, 3.75-7.73). CONCLUSION Patients with hypertensive disorders of pregnancy are at an elevated risk of severe maternal morbidity, and development of severe hypertension further increases this risk. Timely antihypertensive treatment is associated with lower risk of severe maternal morbidity among those with severe hypertension. These findings emphasize the importance of provider education and quality improvement efforts aimed at expediting treatment of severe hypertension.

Abstract
BACKGROUND SARS-CoV-2 infection during pregnancy is associated with adverse pregnancy outcomes, including fetal death and preterm birth. It is not known whether that risk occurs only during the time of acute infection or whether the risk persists later in pregnancy. OBJECTIVE This study aimed to evaluate whether the risk of SARS-CoV-2 infection during pregnancy persists after an acute maternal illness. STUDY DESIGN A retrospective cohort study of pregnant patients with and without SARS-CoV-2 infection delivering at 17 hospitals in the United States between March 2020 and December 2020. Patients experiencing a SARS-CoV-2-positive test at or before 28 weeks of gestation with a subsequent delivery hospitalization were compared with those without a positive SAR-CoV-2 test at the same hospitals with randomly selected delivery days during the same period. Deliveries occurring at <20 weeks of gestation in both groups were excluded. The study outcomes included fetal or neonatal death, preterm birth at <37 weeks of gestation and <34 weeks of gestation, hypertensive disorders of pregnancy (HDP), any major congenital malformation, and size for gestational age of <5th or <10th percentiles at birth based on published standards. HDP that were collected included HDP and preeclampsia with severe features, both overall and with delivery at <37 weeks of gestation. RESULTS Of 2326 patients who tested positive for SARS-CoV-2 during pregnancy and were at least 20 weeks of gestation at delivery from March 2020 to December 2020, 402 patients (delivering 414 fetuses or neonates) were SARS-CoV-2 positive before 28 weeks of gestation and before their admission for delivery; they were compared with 11,705 patients without a positive SARS-CoV-2 test. In adjusted analyses, those with SARS-CoV-2 before 28 weeks of gestation had a subsequent increased risk of fetal or neonatal death (2.9% vs 1.5%; adjusted relative risk, 1.97; 95% confidence interval, 1.01-3.85), preterm birth at <37 weeks of gestation (19.6% vs 13.8%; adjusted relative risk, 1.29; 95% confidence interval, 1.02-1.63), and HDP with delivery at <37 weeks of gestation (7.2% vs 4.1%; adjusted relative risk, 1.74; 95% confidence interval, 1.19-2.55). There was no difference in the rates of preterm birth at <34 weeks of gestation, any major congenital malformation, and size for gestational age of <5th or <10th percentiles. In addition, there was no significant difference in the rate of gestational hypertension overall or preeclampsia with severe features. CONCLUSION There was a modest increase in the risk of adverse pregnancy outcomes after SARS-CoV-2 infection.

Abstract
BACKGROUND Hypertension is a key contributor to the global epidemic of cardiovascular disease and is responsible for more deaths worldwide than any other cardiovascular risk factor. Hypertensive disorders of pregnancy, of which preeclampsia and eclampsia are the most common forms, have been shown to be a female-specific risk factor for chronic hypertension. OBJECTIVE This study aimed to determine the proportion and risk factors for persistent hypertension at 3 months after delivery among women with hypertensive disorders of pregnancy in Southwestern Uganda. STUDY DESIGN This was a prospective cohort study of pregnant women with hypertensive disorders of pregnancy admitted for delivery at Mbarara Regional Referral Hospital in Southwestern Uganda from January 2019 to December 2019; however, women with chronic hypertension were excluded from the study. The participants were followed up for 3 months after delivery. Participants with a systolic blood pressure of ≥140 mm Hg or a diastolic blood pressure of ≥90 mm Hg or receiving antihypertension therapy at 3 months after delivery were considered to have persistent hypertension. Multivariable logistic regression was used to determine independent risk factors associated with persistent hypertension. RESULTS A total of 111 participants with hypertensive disorders of pregnancy diagnosed at hospital admission were enrolled with a follow-up rate of 49% (54/111) at 3 months after delivery. Of these women, 21 of 54 (39%) had persistent hypertension 3 months after delivery. In the adjusted analyses, an elevated serum creatinine level (>106.08 µmol/L [≤1.2 mg/dL]) at admission for delivery was the only independent risk factor for persistent hypertension at 3 months after delivery (adjusted relative risk, 1.93; 95% confidence interval, 1.08-3.46; P=.03), controlling for age, gravidity, and eclampsia. CONCLUSION Approximately 4 of 10 women presenting with hypertensive disorders of pregnancy at our institution remained hypertensive 3 months after delivery. Innovative strategies are needed to identify these women and provide long-term care to optimize blood pressure control and reduce future cardiovascular disease after hypertensive disorders of pregnancy.
