Abstract
Background and purposeThough hypertension disorders of pregnancy (HDP) are recognized as independent pregnancy-associated stroke risk factors, few studies have considered their impact on stroke prognosis. Therefore, we intended to evaluate the impact of HDP on short- and long-term outcomes of pregnancy-associated hemorrhagic stroke (HS).MethodsWe conducted a retrospective analysis of patients admitted to our hospital from May 2009 to December 2021 with a diagnosis of pregnancy-associated HS. After dividing patients into two groups by the presence of a diagnosis of HDP or not, the short- (at the time of discharge) and long-term (after discharge follow-up) outcomes were compared by mRS (modified Rankin Scale) scores, and poor functional outcome defined as mRS > 2. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were reported.ResultsTwenty-two HDP and 72 non-HDP pregnancy-associated HS patients were enrolled and follow-up after 4.7 ± 3.6 years. There was no significant difference between the two groups regarding short-term outcomes, but patients with HDP were more likely to reach poor functional outcomes at long-term follow-up (aOR = 4.47, 95% CI = 1.28–15.67, p = 0.019).ConclusionsIn this retrospective study, women with hypertension disorders of pregnancy did not show worse short-term outcomes of pregnancy-associated hemorrhagic stroke compared to those without but had poorer long-term functional outcomes. This underlines the importance of prevention, recognition, and treatment of hypertension disorders in these women.

Abstract
BACKGROUND Management of postpartum stroke has been the focus of several quality improvement efforts in the past decade. However, there is little recent national trends data for postpartum stroke readmissions. OBJECTIVE This study aimed to determine trends, risk factors, and complications associated with postpartum stroke readmission. STUDY DESIGN The 2013 to 2019 Nationwide Readmissions Database was used to perform a retrospective cohort study that evaluated the risk for readmission for stroke within 60 days of delivery hospitalization discharge. Temporal trends in readmissions were analyzed using the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% confidence intervals. Stratified trends were analyzed for hemorrhage stroke, ischemic stroke, and stroke readmissions at 1 to 10, 11 to 30, and 31 to 60 days after delivery discharge. Risk factors for stroke were analyzed using unadjusted and adjusted logistic regression models with odds ratios and 95% confidence intervals as measures of association. The risk for stroke complications, including mechanical ventilation, seizures, death, and a prolonged stay ≥14 days, was analyzed. RESULTS Of an estimated 21,754,603 delivery hospitalizations, 5006 were complicated by a 60-day postpartum readmission with a diagnosis of stroke. The average annual percent change for all stroke readmissions over the study period was not significant (average annual percent change, 0.1%; 95% confidence interval, -2.2% to 2.4%). When the trends in readmission for ischemic and hemorrhagic stroke were analyzed, the results were similar, as were the stratified analyses by readmission timing. Risk factors associated with increased odds included superimposed preeclampsia (odds ratio, 4.8; 95% confidence interval, 3.9-5.9), preeclampsia with severe features (odds ratio, 3.7; 95% confidence interval, 3.0-4.4), maternal cardiac disease (odds ratio, 3.0; 95% confidence interval, 2.5-3.7), chronic kidney disease (odds ratio, 5.0; 95% confidence interval, 3.4-7.5), and lupus (odds ratio, 7.0; 95% confidence interval, 4.9-10.2). Risk was retained in adjusted analyses. Common stroke-related complications included a prolonged hospital stay ≥14 days (12.1 per 1000 stroke-related readmissions), seizures (9.9 per 1000 stroke-related readmissions), and mechanical ventilation (6.6 per 1000 stroke-related readmissions). CONCLUSION This analysis of nationally representative data demonstrated no change in the rate of 60-day postpartum hospitalizations for stroke from 2013 to 2019. Further clinical research is indicated to optimize risk reduction for stroke after delivery hospitalization discharge.

Abstract
BACKGROUND Preeclampsia is associated with maternal and perinatal morbidity. Besides acute therapy for severe hypertension, best practices are lacking for intrapartum hypertension management. Our objective was to test the hypothesis that intrapartum initiation of extended-release nifedipine in individuals with preeclampsia with severe features prevents severe hypertension. METHODS Randomized, triple-blind, placebo-controlled trial of individuals with preeclampsia with severe features undergoing labor induction between 220/7 and 416/7 weeks gestation. Participants were randomized to oral extended-release nifedipine 30 mg or identical placebo every 24 hours. Primary outcome is defined as receipt of ≥1 dose of acute hypertension therapy for severe blood pressure (≥160/110 mm Hg) sustained ≥10 minutes. Secondary outcomes included route of delivery, neonatal intensive care unit admission, and a composite of adverse neonatal outcomes. RESULTS Of 365 individuals screened, 55 were randomized to nifedipine and 55 to placebo. Primary outcome was observed in 34.0% of individuals in nifedipine group versus 55.1% in placebo group (relative risk [RR] 0.62 [95% CI, 0.39-0.97]); number needed to treat to prevent receipt of acute treatment was 4.7 (95% CI, 2.5-44.3). Fewer individuals in nifedipine group required cesarean delivery compared with placebo group (20.8% versus 34.7%, RR, 0.60 [95% CI, 0.31-1.15]). Neonatal intensive care unit admission rate was lower in nifedipine group compared with placebo (29.1% versus 47.1%; RR 0.62 [95% CI, 0.37-1.02]). Neonatal composite was similar between groups (35.8% versus 41.2%, RR, 0.83 [95% CI, 0.51-1.37]). CONCLUSIONS Initiation of extended-release nifedipine is effective in reducing intrapartum acute hypertensive therapy among individuals with preeclampsia with severe features.

Abstract
OBJECTIVE To analyse trends, risk factors, and outcomes related to hypertensive disorders of pregnancy (HDP). DESIGN Repeated cross-sectional. SETTING US delivery hospitalisations. POPULATION Delivery hospitalisations in the 2000-2018 National Inpatient Sample. METHODS US hospital delivery hospitalisations with HDP were analysed. Several trends were analysed: (i) the proportion of deliveries by year with HDP, (ii) the proportion of deliveries with HDP risk factors and (iii) adverse outcomes associated with HDP including maternal stroke, acute renal failure and acute liver injury. Risk ratios were determined using regression models with HDP as the exposure of interest. MAIN OUTCOME MEASURES Prevalence of HDP, risk factors for HDP and associated adverse outcomes. RESULTS Of 73.1 million delivery hospitalisations, 7.7% had an associated diagnosis of HDP. Over the study period, HDP doubled from 6.0% of deliveries in 2000 to 12.0% in 2018. The proportion of deliveries with risk factors for HDP increased from 9.6% in 2000 to 24.6% in 2018. In adjusted models, HDP were associated with increased stroke (aRR [adjusted risk ratio] 15.9, 95% CI 14.8-17.1), acute renal failure (aRR 13.8, 95% CI 13.5-14.2) and acute liver injury (aRR 1.2, 95% CI 1.2-1.3). Among deliveries with HDP, acute renal failure and acute liver injury increased; in comparison, stroke decreased. CONCLUSION Hypertensive disorders of pregnancy increased in the setting of risk factors for HDP becoming more common, whereas stroke decreased. TWEETABLE ABSTRACT While hypertensive disorders of pregnancy increased from 2000 to 2018, stroke appears to be decreasing.

Abstract
INTRODUCTION Hypertensive disorders of pregnancy (HDP) are rising in prevalence, and increase risk of adverse maternal and fetal outcomes. Physiologic changes occur during pregnancy that alter drug pharmacokinetics. However, antihypertensive drugs lack pregnancy-specific dosing recommendations due to critical knowledge gaps surrounding the extent of gestational changes in antihypertensive drug pharmacokinetics and underlying mechanisms. AREAS COVERED This review (1) summarizes currently recommended medications and dosing strategies for non-emergent HDP treatment, (2) reviews and synthesizes existing literature identified via a comprehensive Pubmed search evaluating gestational changes in the maternal pharmacokinetics of commonly prescribed HDP drugs (notably labetalol and nifedipine), and (3) offers insight into the metabolism and clearance mechanisms underlying altered HDP drug pharmacokinetics during pregnancy. Remaining knowledge gaps and future research directions are summarized. EXPERT OPINION A series of small pharmacokinetic studies illustrate higher oral clearance of labetalol and nifedipine during pregnancy. Pharmacokinetic modeling and preclinical studies suggest these effects are likely due to pregnancy-associated increases in hepatic UGT1A1- and CYP3A4-mediated first-pass metabolism and lower bioavailability. Accordingly, higher and/or more frequent doses may be needed to lower blood pressure during pregnancy. Future research is needed to address various evidence gaps and inform the development of more precise antihypertensive drug dosing strategies.

Abstract
Background Preeclampsia can cause severe consequences for pregnant women and infants, and developing effective medicine or methods to prevent or treat patients with preeclampsia is urgently needed. Ubiquitin‐specific protease 14 (USP14) has emerged as a critical regulator in the development of human cancers and neurodegenerative diseases. However, its role in preeclampsia remains elusive. Methods The expression of USP14 in placental tissues from healthy donors and preeclampsia patients were determined by quantitative reverse transcription PCR assay. The protein levels of targeted genes were evaluated by Western blotting assay. Small interfering RNA‐mediated gene knockdown was used to reduce USP14 expression in trophoblast cell lines. Results The expression levels of USP14 and proinflammatory cytokine were substantially upregulated in placental tissues from preeclampsia patients. Knockdown or inhibition of USP14 significantly abrogated hypoxia/reoxygenation‐induced upregulation of nuclear factor kappa B (NF‐κB) activation and proinflammatory cytokine production. Conclusion Our results suggested that USP14 promotes proinflammatory cytokine production through activation of NF‐κB. Developing drugs targeting USP14 may be beneficial for the prevention or treatment of patients with preeclampsia.

Abstract
OBJECTIVE To evaluate whether implementation of a semiautonomous treatment algorithm was associated with improved compliance with American College of Obstetricians and Gynecologists guidelines for rapid administration of antihypertensive therapy in the setting of sustained severe hypertension. METHODS This was a single-center retrospective cohort study of admitted pregnant and postpartum patients treated for severe hypertension between January 2017 and March 2020. The semiautonomous treatment algorithm, which included vital sign monitoring, blood pressure thresholds for diagnosis of severe hypertension, and automated order sets for recommended first-line antihypertensive therapy were implemented between May 2018 and March 2019. The primary outcomes were the administration of antihypertensive therapy within 15, 30 and 60 minutes of diagnosis of severe hypertension. Comparisons were made between the preimplementation, during implementation, and postimplementation groups using χ2. Analysis was limited to the first episode of severe hypertension treated. Statistical significance was defined as P<.05. RESULTS In total, there were 959 obstetric patients treated for severe hypertension, with 373 (38.9%) treated preimplementation, 334 (34.8%) during implementation, and 252 (26.2%) after implementation. Treatment of severe hypertension within 15 minutes was 36.5% preimplementation, 45.8% during implementation, and 55.6% postimplementation (P=.001). Treatment within 30 minutes was 65.9% in the preimplementation group, 77.8% during implementation, and 79.0% in the postimplementation group (P=.004). There was no difference in percentage of patients treated within 60 minutes (86.3% before, 87.7% during and 92.9% after implementation, P=.12). CONCLUSION Implementation of a semiautonomous treatment algorithm for severe hypertension was associated with a higher percentage of pregnant and postpartum patients receiving the first dose of antihypertensive therapy within 15 and 30 minutes. Implementation of similar algorithms for this and other obstetric indications may decrease time to appropriate therapy and help improve care equity.

Pregnancy-related hormones (PRH) are recognized as important regulators of hepatic cytochrome P450 enzyme expression and function. However, the impact of PRH on the hepatic expression and function of uridine diphosphate glucuronosyltransferases (UGTs) remains unclear. Using primary human hepatocytes, we evaluated the effect of PRH exposure on mRNA levels and protein concentrations of UGT1A1, UGT2B7, and other key UGT enzymes, and on the metabolism of labetalol (a UGT1A1 and UGT2B7 substrate commonly prescribed to treat hypertensive disorders of pregnancy). Sandwich-cultured human hepatocytes (SCHH) from female donors were exposed to the PRH estradiol, estriol, estetrol, progesterone, and cortisol individually or in combination. We quantified protein concentrations of UGT1A1, UGT2B7, and four additional UGT1A isoforms in SCHH membrane fractions and evaluated the metabolism of labetalol to its glucuronide metabolites in SCHH. PRH exposure increased mRNA levels and protein concentrations of UGT1A1 and UGT1A4 in SCHH. PRH exposure also significantly increased labetalol metabolism to its UGT1A1-derived glucuronide metabolite in a concentration-dependent manner, which positively correlated with PRH-induced changes in UGT1A1 protein concentrations. In contrast, PRH did not alter UGT2B7 mRNA levels or protein concentrations in SCHH, and formation of the UGT2B7-derived labetalol glucuronide metabolite was decreased following PRH exposure. Our findings demonstrate that PRH alter expression and function of UGT proteins in an isoform-specific manner and increase UGT1A1-mediated labetalol metabolism in human hepatocytes by inducing UGT1A1 protein concentrations. These results provide mechanistic insight into the increases in labetalol clearance observed in pregnant individuals.

Abstract
PURPOSE OF REVIEW Preeclampsia and related hypertensive disorders of pregnancy affect up to 10% of pregnancies. Neurological complications are common and neurologists often become involved in the care of obstetric patients with preeclampsia. Here, we review the definition(s), epidemiology, clinical features, and pathophysiology of preeclampsia, focusing on maternal neurological complications and headache as a common presenting symptom of preeclampsia. RECENT FINDINGS Neurological symptoms are early and disease-defining features of preeclampsia. Neurological complications of preeclampsia may include headaches, visual symptoms, cerebral edema, seizures, or acute cerebrovascular disorders such as intracerebral hemorrhage or reversible cerebral vasoconstriction syndrome. A history of migraine is an independent risk factor for vascular diseases during pregnancy, including preeclampsia and maternal stroke. The pathophysiology of both preeclampsia and migraine is complex, and the mechanisms linking the two are not fully understood. Overlapping clinical and pathophysiological features of migraine and preeclampsia include inflammation, vascular endothelial dysfunction, and changes in vasoreactivity. Neurological complications are recognized as a major contributor to maternal morbidity and mortality. Pregnant and postpartum women commonly present with headache, and red flags in the clinical history and examination should prompt urgent neuroimaging and laboratory evaluation. A focused headache history should be elicited from patients as part of routine obstetrical care to identify patients at an increased risk of preeclampsia and related hypertensive disorders of pregnancy. Collaborative models of care and scientific investigation in the emerging field of neuro-obstetrics have the common goal of reducing the risk of maternal neurological morbidity and mortality from preeclampsia.

Abstract
Preeclampsia is a severe gestational hypertensive condition linked to child neuropsychiatric disorders, although underlying mechanisms are unclear. We used a recently developed, clinically relevant animal model of preeclampsia to assess offspring. C57BL/6J mouse dams were chronically infused with arginine vasopressin (AVP) or saline (24 ng/h) throughout pregnancy. Adult offspring were behaviorally tested (Y-maze, open field, rotarod, social approach, and elevated plus maze). Offspring brain was assessed histologically and by RNA sequencing. Preeclampsia-exposed adult males exhibited increased anxiety-like behavior and social approach while adult females exhibited impaired procedural learning. Adult AVP-exposed males had reduced total neocortical volume. Adult AVP-exposed females had increased caudate-putamen volume, increased caudate-putamen cell number, and decreased excitatory synapse density in hippocampal dentate gyrus (DG), CA1, and CA3. At postnatal day 7 (P7), AVP-exposed male and female offspring both had smaller neocortex. At P7, AVP-exposed males also had smaller caudate-putamen volume, while females had increased caudate-putamen volume relative to neocortical size. Similar to P7, E18 AVP-exposed offspring had smaller dorsal forebrain, mainly in reduced intermediate, subventricular, and ventricular zone volume, particularly in males. Decreased volume was not accounted for by cell size or cerebrovascular vessel diameter changes. E18 cortical RNAseq revealed 49 differentially-expressed genes in male AVP-exposed offspring, over-representing cytoplasmic translation processes. In females, 31 genes were differentially-expressed, over-representing collagen-related and epithelial regulation pathways. Gene expression changes in E18 AVP-exposed placenta indicated potential underlying mechanisms. Deficits in behavior and forebrain development in this AVP-based preeclampsia model were distinctly different in males and females, implicating different neurobiological bases.

Abstract
Administrative data research on maternal racial disparities supports 2 broad clinical inferences. First, failure to rescue in terms of both death and severe maternal morbidity likely accounts for a significant proportion of maternal disparities. Second, risk for adverse outcomes by race is generally differential with risk for cardiovascular complications particularly high for non-Hispanic black women. These differentials suggest that underlying health conditions may represent an important contributor to overall disparities, and optimal longitudinal care utilization with nonobstetric specialists is required to mitigate risk.

Abstract
BACKGROUND Obstetric hypertensive emergency is defined as having systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥110 mm Hg, confirmed 15 minutes apart. The American College of Obstetricians and Gynecologists recommends that acute-onset, severe hypertension be treated with first line-therapy (intravenous labetalol, intravenous hydralazine or oral nifedipine) within 60 minutes to reduce risk of maternal morbidity and death. OBJECTIVE Our objective was to identify barriers that lead to delayed treatment of obstetric hypertensive emergency. STUDY DESIGN A retrospective cohort study was performed that compared women who were treated appropriately within 60 minutes vs those with delay in first-line therapy. We identified 604 patients with discharge diagnoses of chronic hypertension, gestational hypertension, or preeclampsia using International Classification of Diseases-10 codes and obstetric antihypertensive usage in a pharmacy database at 1 academic institution from January 2017 through June 2018. Of these, 267 women (44.2%) experienced obstetric hypertensive emergency in the intrapartum period or within 2 days of delivery; the results from 213 women were used for analysis. We evaluated maternal characteristics, presenting symptoms and circumstances, timing of hypertensive emergency, gestational age at presentation, and administered medications. Chi square, Fisher's exact, Wilcoxon rank-sum, and sample t-tests were used to compare the 2 groups. Univariable logistic regression was applied to determine predictors of delayed treatment. Multivariable regression model was also performed; C-statistic and Hosmer and Lemeshow goodness-of-fit test were used to assess the model fit. A result was considered statistically significant at P<.05. RESULTS Of the 213 women, 110 (51.6%) had delayed treatment vs 103 (48.4%) who were treated within 60 minutes. Patients who had delayed treatment were 3.2 times more likely to have an initial blood pressure in the nonsevere range vs those who had timely treatment (odds ratio, 3.24; 95% confidence interval, 1.85-5.68). Timeliness of treatment was associated with presence or absence of preeclampsia symptoms; patients without preeclampsia symptoms were 2.7 times more likely to have delayed treatment (odds ratio, 2.68; 95% confidence interval, 1.50-4.80). Patients with hypertensive emergencies that occurred overnight between 10 pm and 6 am were 2.7 times more likely to have delayed treatment vs those emergencies that occurred between 6 am and 10 pm (odds ratio, 2.72; 95% confidence interval, 1.27-5.83). Delayed treatment also had an association with race, with white patients being 1.8 times more likely to have delayed treatment (odds ratio, 1.79; 95% confidence interval, 1.04-3.08). Patients who were treated at <60 minutes had a lower gestational age at presentation vs those with delayed treatment (34.6±5 vs 36.6±4 weeks, respectively; P<.001). For every 1-week increase in gestational age at presentation, there was a 9% increase in the likelihood of delayed treatment (odds ratio, 1.11; 95% confidence interval, 1.04-1.19). Another factor that was associated with delay of treatment was having a complaint of labor symptoms, which made patients 2.2 times as likely to experience treatment delay (odds ratio, 2.17; 95% confidence interval, 1.07-4.41). CONCLUSION Initial blood pressure in the nonsevere range, absence of preeclampsia symptoms, presentation overnight, white race, having complaint of labor symptoms, and increasing gestational age at presentation are barriers that lead to a delay in the treatment of obstetric hypertensive emergency. Quality improvement initiatives that target these barriers should be instituted to improve timely treatment.

Abstract
Background Racial disparities contribute to maternal morbidity in the United States. Hypertension is associated with poor maternal outcomes, including stroke. Disparities in hypertension might contribute to maternal strokes. Methods and Results Using billing data from the Healthcare Cost and Utilization Project's National Inpatient Sample, we analyzed the effect of race/ethnicity on stroke during delivery admission in women aged 18 to 54 years delivering in US hospitals from January 1, 1998, through December 31, 2014. We categorized hypertension as normotensive, chronic hypertension, or pregnancy‐induced hypertension. Adjusted risk ratios (aRRs) and 95% CIs were calculated using log‐linear Poisson regression models, testing for interactions between race/ethnicity and hypertensive status. A total of 65 286 425 women were admitted for delivery during the study period, of whom 7764 were diagnosed with a stroke (11.9 per 100 000 deliveries). Hypertension modified the effect of race/ethnicity (P<0.0001 for interaction). Among women with pregnancy‐induced hypertension, black and Hispanic women had higher stroke risk compared with non‐Hispanic whites (blacks: aRR, 2.07; 95% CI, 1.86–2.30; Hispanics: aRR, 2.19; 95% CI, 1.98–2.43). Among women with chronic hypertension, all minority women had higher stroke risk (blacks: aRR, 1.71; 95% CI, 1.30–2.26; Hispanics: aRR, 1.75; 95% CI, 2.32–5.63; Asian/Pacific Islanders: aRR, 3.62; 95% CI, 2.32–5.63). Among normotensive women, only blacks had increased stroke risk (aRR, 1.17; 95% CI, 1.07–1.28). Conclusions Pregnant US women from minority groups had higher stroke risk during delivery admissions, compared with non‐Hispanic whites. The effect of race/ethnicity was larger in women with chronic hypertension or pregnancy‐induced hypertension. Targeting blood pressure management in pregnancy may help reduce maternal stroke risk in minority populations.

Abstract
INTRODUCTION Hypertensive disorders of pregnancy (HDP) represent a major cause of maternal, fetal and neonatal morbidity and mortality and identifies women at risk for cardiovascular and other chronic diseases later in life. When antihypertensive drugs are used during pregnancy, their benefit and harm to both mother and fetus should be evaluated. AREAS COVERED This review summarizes the pharmacological characteristics of the recommended antihypertensive drugs and their impact on mother and fetus when administered during pregnancy and/or post-partum. Drugs were identified using MEDLINE and the main international Guidelines for the management of HDP. EXPERT OPINION Although there is a consensus that severe hypertension should be treated, treatment of mild hypertension without end-organ damage (140-159/90-109 mmHg) remains controversial and there is no agreement on when to initiate therapy, blood pressure targets or recommended drugs in the absence of robust evidence for the superiority of one drug over others. Furthermore, the long-term outcomes of in-utero antihypertensive exposure remain uncertain. Therefore, evidence-based data regarding the treatment of HDP is lacking and well designed randomized clinical trials are needed to resolve all these controversial issues related to the management of HDP.

Abstract
BACKGROUND Although stroke is more common with advancing age, especially in the elderly, women of reproductive age may still suffer from stroke, and from its deleterious consequences. Women of reproductive age who suffer a stroke may do so either due to a specific predisposition, or due to pregnancy-related hypertensive emergencies. OBJECTIVE To assess the risk of stroke recurrence in pregnancy and the postpartum period in women who have suffered a stroke before pregnancy. STUDY DESIGN This was a retrospective cohort study conducted at Thomas Jefferson University Hospital from January 2005 to December 2015. This is a tertiary referral center for high-risk obstetrics and one of the largest stroke referral centers for neurosurgery. All consecutive pregnant women that had a viable pregnancy (≥24 weeks of gestation) and a history of stroke prior to pregnancy were identified. The primary outcome of this study was stroke recurrence in pregnancy or the postpartum period defined as 6 weeks after delivery. RESULTS Forty-eight pregnancies with a history of stroke before pregnancy were identified in 24 women. Thirty-one pregnancies (64.6%) had a history of an ischemic stroke, 11 (22.9%) had a history of transient ischemic attack, and 6 (12.5%) had a history of a hemorrhagic stroke. There was no stroke recurrence during pregnancy or the postpartum period for the three groups of stroke. In the ischemic stroke group, 8 (25.8%) had recurrence in the non-pregnant state compared to none in the TIA and the hemorrhagic stroke group. CONCLUSION There was no stroke recurrence during pregnancy or the postpartum period for the three groups of stroke.

Abstract
Preeclampsia (PE), a disorder of new-onset maternal hypertension and vascular dysfunction during pregnancy, is thought to be linked to placental ischemia-induced release of prohypertensive factors and reductions of vasoprotective factors in the maternal circulation. Although markers of sympathetic nervous activity are elevated in experimental models of placental ischemia-induced hypertension and women with PE compared with their normal pregnant counterparts, the importance of adrenergic receptor signaling in the development of hypertension in PE is unknown. Therefore, we tested the hypothesis that adrenergic receptor blockade attenuates the development of placental ischemia-induced hypertension in rats. Wistar Hannover rats underwent reduced uterine perfusion pressure (RUPP) or Sham surgeries on gestational day 14. By day 19, mean arterial blood pressure (MAP) was increased in RUPP over Sham rats. Groups of RUPP and Sham pregnant rats received terazosin and propranolol (3 mg/kg per day of each via subcutaneous osmotic minipump) to block α1- and β-adrenergic receptors, respectively, beginning on gestational day 14. Adrenergic blockade significantly attenuated the development of hypertension in the RUPP rats with a slight blood pressure-lowering response in the Sham, normal pregnant rats by day 19. In conclusion, these data implicate that placental ischemia-induced hypertension involves adrenergic receptor signaling to promote increases in blood pressure during PE.

Abstract
OBJECTIVE The objective of this study was to characterize morbidity, acuity, and maternal risks associated with preeclampsia across hospitals with varying obstetric volumes. METHODS This retrospective cohort analysis used a large administrative data source, the Perspective database, to characterize the risk for preeclampsia from 2006 to 2015. Hospitals were classified as having either low (≤1000), moderate (1001-2000), or high (≥2000) delivery volume. The primary outcomes included preeclampsia, antihypertensive administration, comorbidity, and related severe maternal morbidity. Severe maternal morbidity was estimated using criteria from the Centers for Disease Control and Prevention. Comorbidity was estimated using an obstetric comorbidity index. Univariable comparisons were made with Chi-squared test. Adjusted log linear regression models were fit to assess factors associated with severe morbidity with risk ratios with 95% confidence intervals as the measures of effect. Population weights were applied to create national estimates. RESULTS Of 36,985,729 deliveries included, 1,414,484 (3.8%) had a diagnosis of preeclampsia. Of these, 779,511 (2.1%) had mild, 171,109 (0.5%) superimposed, and 463,864 (1.3%) severe preeclampsia. The prevalence of mild, superimposed, and severe preeclampsia each increased over the study period with severe and superimposed preeclampsia as opposed to mild preeclampsia increasing the most proportionately (53.2 and 102.5 versus 10.8%, respectively). The use of antihypertensives used to treat severe range hypertension increased with use of intravenous labetalol increasing 31.5%, 43.2%, and 36.1% at low-, medium-, and high-volume hospitals. Comorbid risk also increased across hospital volume settings as did risk for severe maternal morbidity. CONCLUSIONS Preeclampsia is increasing across obstetric care settings with preeclamptic patients demonstrating increasing comorbid risk, increased risk for severe morbidity, and more frequent need for treatment of acute hypertension.

Abstract
Pregnancy-related hypertension (PHTN) syndromes are a frequent and potentially deadly complication of pregnancy, while also negatively impacting the lifelong health of the mother and child. PHTN appears in women likely to develop hypertension later in life, with the stress of pregnancy unmasking a subclinical hypertensive phenotype. However, distinguishing between PHTN and chronic hypertension is essential for optimal management. Preeclampsia (PE) is linked to potentially severe outcomes and lacks effective treatments due to poorly understood mechanisms. Inadequate remodeling of spiral uterine arteries (SUAs), the cornerstone of PE pathophysiology, leads to hypoperfusion of the developing placenta. In normal pregnancies, extravillous trophoblast (EVT) cells assume an invasive phenotype and invade SUAs, transforming them into large conduits. Decidual natural killer cells play an essential role, mediating materno-fetal immune tolerance, inducing early SUA remodeling and regulating EVT invasiveness. Notch signaling is important in EVT phenotypic switch and is dysregulated in PE. The hypoxic placenta releases antiangiogenic and proinflammatory factors that converge upon maternal endothelium, inducing endothelial dysfunction, hypertension, and organ damage. Hypoxia-inducible factor 1-α is upstream of such molecules, whereas endothelin-1 is a major effector. We also describe important genetic links and evidence of incomplete materno-fetal immune tolerance, with PE patients presenting with autoantibodies, lower Treg , and higher Th 17 cells. Thus, PE manifestations arise as a consequence of mal-placentation or/and because of a predisposition of the maternal vascular bed to excessively react to pathogenic molecules. From this pathophysiological basis, we provide current and propose future therapeutic directions for PE.
