Abstract
OBJECTIVE To assess the cost effectiveness of targeting a blood pressure of less than 140/90 mm Hg compared with 160/105 mm Hg. METHODS A decision-analytic model was constructed to compare the treatment of chronic hypertension in pregnancy at mild-range blood pressures (140/90 mm Hg) with the treatment of chronic hypertension before 20 weeks of gestation at severe-range blood pressures (160/105 mm Hg) in a theoretical cohort of 180,000 patients with mild chronic hypertension. Probabilities, costs, and utilities were derived from literature and varied in sensitivity analyses. Primary outcomes included incremental cost per quality-adjusted life-year (QALY), cases of preeclampsia, preeclampsia with severe features, severe maternal morbidity (SMM), preterm birth, maternal death, neonatal death, and neurodevelopmental delay. The cost-effectiveness threshold was $100,000 per QALY. RESULTS Treating chronic hypertension in a population of 180,000 pregnant persons at mild-range blood pressures, compared with severe-range blood pressures, resulted in 14,177 fewer cases of preeclampsia (43,953 vs 58,130), 11,835 of which were cases of preeclampsia with severe features (40,530 vs 52,365). This led to 817 fewer cases of SMM (4,375 vs 5,192), and 18 fewer cases of maternal death (102 vs 120). Treating at a lower threshold also resulted in 8,078 fewer cases of preterm birth (22,000 vs 30,078), which led to 26 fewer neonatal deaths (276 vs 302) and 157 fewer cases of neurodevelopmental delay (661 vs 818). Overall, treating chronic hypertension at a lower threshold was a dominant strategy that resulted in decreased costs of $600 million and increased effectiveness of 12,852 QALYs. CONCLUSION Treating chronic hypertension at a threshold of mild-range blood pressures is a dominant (lower costs, better outcomes) and cost-effective strategy that results in fewer neonatal and maternal deaths compared with the standard treatment of treating at severe range blood pressures.

Abstract
OBJECTIVE The aim of the study is to evaluate the association between the amount of proteinuria at the time of diagnosis of preeclampsia with severe features (severe preeclampsia [SPE]) and duration of expectant management (EM) and other perinatal outcomes. STUDY DESIGN This is a retrospective cohort study of patients with SPE delivering live, non-anomalous singletons at 230/7 to 342/7 weeks' estimated gestational age (EGA) at a single tertiary center 2016 to 2018. Patients with proteinuria assessment (24-hour total urine protein or urine protein-to-creatinine ratio extrapolation) within 3 days of SPE diagnosis were included. Patients delivered for an indication other than SPE were excluded. Patients were categorized by amount of proteinuria (mg): none (≤300), mild (301-1,000), moderate (1,001-3,000), and massive (≥3,001). The primary outcome was the proportion of potential EM time achieved (%EM), i.e., days of EM divided by days from SPE diagnosis to 34 weeks. Secondary outcomes included delivery EGA, days of EM, and perinatal outcomes. Bivariable and multivariable analyses compared outcomes across groups. RESULTS Of 295 patients included, 21% had no proteinuria, 33% mild, 19% moderate, and 27% massive. Groups differed by EGA at diagnosis, age, parity, chronic hypertension, and renal disease. %EM was not significantly different between groups (adjusted β coefficient 4.1 [95% CI -5.3, 13.5] for mild proteinuria vs. none, -4.1 [95% CI -14.9, 6.6] for moderate proteinuria vs. none, and -5.6 [95% CI -16.0, 4.7] for massive proteinuria vs. none). Increasing proteinuria was associated with earlier delivery EGA but only days of EM in the mild versus no proteinuria groups. There was no significant association between proteinuria and maternal composite morbidity, but patients with mild and massive proteinuria had higher odds of neonatal composite morbidities compared with no proteinuria. CONCLUSION Among patients with SPE, proteinuria level was not consistently associated with duration of EM. However, patients with the greatest amounts of proteinuria may have worse neonatal and selected maternal outcomes. KEY POINTS · Amount of proteinuria was not associated with the duration of expectant management.. · Greater proteinuria was associated with earlier delivery in severe preeclampsia.. · Massive proteinuria in preeclampsia was associated with select adverse maternal and neonatal outcomes..

Abstract
OBJECTIVES This study investigated perceptions of the challenges for patients and health care workers (HCW) in dealing with preeclampsia in Blantyre, Malawi. METHODS A descriptive cross-sectional formative study using semi-structured In-Depth Interviews (IDI) was conducted at Queen Elizabeth Central Hospital (QECH), Malawi. Data was analyzed using NVIVO™ software. Thematic content analysis was used to analyze and interpret the findings. Emerging themes were then developed inductively and deductively. Patients were interviewed who recently had preeclampsia. RESULTS Stress, lack of information, physical symptoms, delay in receiving care were identified challenges to better care among patients as well as the impact of poor pregnancy outcomes. Late diagnosis, staff burn out, inadequate skills and lack of resources were expressed as challenge to provide better management by the interviewed HCWs. CONCLUSION Our study showed that a diagnosis of preeclampsia is challenging to both patients and HCWs. These challenges need to be addressed carefully at all levels for optimal management of preeclampsia in Malawi, Africa and in order to improve outcomes.

Abstract
PROBLEM Like other low- and middle-income countries, Ghana has high maternal mortality stemming from pre-eclampsia. Ghanaian midwives are frontline service providers of emergency care in obstetric complications and have the greatest potential to maximise pre-eclampsia outcomes. Little is known about the potential barriers and challenges to midwives' capacity to provide quality care in pre-eclampsia in Ghana. Therefore, we aimed to explore and gain insights into midwives' experiences of pre-eclampsia care including their knowledge, skills, and psychological aspects such as midwives' resilience. BACKGROUND There is a rising global incidence of pre-eclampsia. Quality midwifery care in inter-professional collaborative practice is crucial to reducing pre-eclampsia-related morbidity and mortality. METHODS A qualitative descriptive exploratory study. In-depth semi-structured interviews (n = 35) were performed in 2021 and analysed by thematic analysis. FINDINGS There were three main themes. 1) Competence and Confidence in care; midwives provided timely and appropriate care based on sound knowledge and skills; they explained how pre-eclampsia care was organised within a multidisciplinary context and described collaborative working amongst midwives for mutual learning and support. 2) Emotional concerns and empathy; midwives' described fulfillment in achieving positive pre-eclampsia outcomes. In contrast, maternal loss was distressing and traumatic. 3) Call for improved care resources for pre-eclampsia; midwives recommended expansion of continuing professional development opportunities, appropriate infrastructure, resources, tailored public education, and a review of pre-service education to support their participation in pre-eclampsia care. CONCLUSION To improve the quality of care in pre-eclampsia, midwives should be capacitated, systems should promptly address barriers, and prioritise midwives' emotional well-being.

Abstract
Canadian healthcare suffers rural disparities, especially in maternal and prenatal care. Drawing on a literature review, the paper highlights the potential of mobile health (mHealth) applications to bridge this gap and improve maternal care in rural communities. mHealth tools have great potential for knowledge and trust-building among healthcare workers and pregnant women. To support the success of these solutions, more funding and policy support are required. mHealth solutions have a great potential for great economic savings while addressing healthcare disparities and ensuring everyone has access to high quality care.

Abstract
Preeclampsia (PE) is a common morbid complication during pregnancy, affecting 2%-8% of pregnancies globally and posing serous risks to the health of both mother and fetus. Currently, the only effective treatment for PE is timely termination of pregnancy, which comes with increased perinatal risks. However, there is no effective way to delay pathological progress and improve maternal and fetal outcomes. In light of this, it is of great significance to seek effective therapeutic strategies for PE. Exosomes which are nanoparticles carrying bioactive substances such as proteins, lipids, and nucleic acids, have emerged as a novel vehicle for intercellular communication. Mesenchymal stem cell-derived exosomes (MSC-Exos) participate in various important physiological processes, including immune regulation, cell proliferation and migration, and angiogenesis, and have shown promising potential in tissue repair and disease treatment. Recently, MSC-Exos therapy has gained popularity in the treatment of ischaemic diseases, immune dysfunction, inflammatory diseases, and other fields due to their minimal immunogenicity, characteristics similar to donor cells, ease of storage, and low risk of tumor formation. This review elaborates on the potential therapeutic mechanism of MSC-Exos in treating preeclampsia, considering the main pathogenic factors of the condition, including placental vascular dysplasia, immunological disorders, and oxidative stress, based on the biological function of MSC-Exos. Additionally, we discuss in depth the advantages and challenges of MSC-Exos as a novel acellular therapeutic agent in preeclampsia treatment.

Abstract
OBJECTIVE To identify strategies to reduce maternal and neonatal morbidity related to preeclampsia. MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE® method with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases. The quality of the evidence was assessed (high, moderate, low, very low) and recommendations were formulated as a (i) strong, (ii) weak or (iii) no recommendation. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Preeclampsia is defined by the association of gestational hypertension (systolic blood pressure≥140mmHg and/or diastolic blood pressure≥90mmHg) and proteinuria≥0.3g/24h or a Proteinuria/Creatininuria ratio≥30mg/mmol occurring after 20 weeks of gestation. Data from the literature do not show any benefit in terms of maternal or perinatal health from implementing a broader definition of preeclampsia. Of the 31 questions, there was agreement between the working group and the external reviewers on 31 (100%). In general population, physical activity during pregnancy should be encouraged to reduce the risk of preeclampsia (Strong recommendation, Quality of the evidence low) but an early screening based on algorithms (Weak recommendation, Quality of the evidence low) or aspirin administration (Weak recommendation, Quality of the evidence very low) is not recommended to reduce maternal and neonatal morbidity related to preeclampsia. In women with preexisting diabetes or hypertension or renal disease, or multiple pregnancy, the level of evidence is insufficient to determine whether aspirin administration during pregnancy is useful to reduce maternal and perinatal morbidity (No recommendation, Quality of the evidence low). In women with a history of vasculo-placental disease, low dose of aspirin (Strong recommendation, Quality of the evidence moderate) at a dosage of 100-160mg per day (Weak recommendation, Quality of the evidence low), ideally before 16 weeks of gestation and not after 20 weeks of gestation (Strong recommendation, Quality of the evidence low) until 36 weeks of gestation (Weak recommendation, Quality of the evidence very low) is recommended. In a high-risk population, additional administration of low molecular weight heparin is not recommended (Weak recommendation, Quality of the evidence moderate). In case of preeclampsia (Weak recommendation, Quality of the evidence low) or suspicion of preeclampsia (Weak recommendation, Quality of the evidence moderate, the assessment of PlGF concentration or sFLT-1/PlGF ratio is not routinely recommended) in the only goal to reduce maternal or perinatal morbidity. In women with non-severe preeclampsia antihypertensive agent should be administered orally when the systolic blood pressure is measured between 140 and 159mmHg or diastolic blood pressure is measured between 90 and 109mmHg (Weak recommendation, Quality of the evidence low). In women with non-severe preeclampsia, delivery between 34 and 36+6 weeks of gestation reduces severe maternal hypertension but increases the incidence of moderate prematurity. Taking into account the benefit/risk balance for the mother and the child, it is recommended not to systematically induce birth in women with non-severe preeclampsia between 34 and 36+6 weeks of gestation (Strong recommendation, Quality of evidence high). In women with non-severe preeclampsia diagnosed between 37+0 and 41 weeks of gestation, it is recommended to induce birth to reduce maternal morbidity (Strong recommendation, Low quality of evidence), and to perform a trial of labor in the absence of contraindication (Strong recommendation, Very low quality of evidence). In women with a history of preeclampsia, screening maternal thrombophilia is not recommended (Strong recommendation, Quality of the evidence moderate). Because women with a history of a preeclampsia have an increased lifelong risk of chronic hypertension and cardiovascular complications, they should be informed of the need for medical follow-up to monitor blood pressure and to manage other possible cardiovascular risk factors (Strong recommendation, Quality of the evidence moderate). CONCLUSION The purpose of these recommendations was to reassess the definition of preeclampsia, and to determine the strategies to reduce maternal and perinatal morbidity related to preeclampsia, during pregnancy but also after childbirth. They aim to help health professionals in their daily clinical practice to inform or care for patients who have had or have preeclampsia. Synthetic information documents are also offered for professionals and patients.

Abstract
Preeclampsia (PE) is a major gestational disorder that causes both long- and short-term damage to both the mother and the fetus. Endometrium decidualization and the formation of the placenta are orchestrated by mesenchymal stem cells (MSCs). MSCs obtained from patients with PE exhibit an elevated rate of aging and apoptosis, which impairs the interplay between MSCs and endothelium, trophoblast, and immune cells in the placenta, accelerating the onset of PE. Preclinical and clinical evidence imply that the MSC-based therapy approach for PE is prospective. Importantly, as a novel cell-free approach, MSC-derived exosomes can improve symptoms and maternal-fetal survival in PE models by raising cell metabolism, encouraging angiogenesis balance, and regulating immune responses. Even following allogeneic administration, the likelihood of immune rejection is very limited as a result of the small quantity of exosome membrane-bound proteins. Furthermore, because exosomes do not expand, developing tumors is not probable. As a result, MSC-derived exosomes show superiority over MSCs in terms of safety. For the first time, we outline the properties of MSC-exosomes and highlight their functions and potential as a new paradigm for PE therapy in this review.

Abstract
Pre-eclampsia (PE) is the most common complication of pregnancy and seriously threatens the health and safety of the mother and child. Studies have shown that an imbalance in gut microbiota can affect the progression of PE. Trimethylamine N-oxide (TMAO) is an intestinal microbiota-derived metabolite that is thought to be involved in the occurrence of PE; however, its causal relationship and mechanism remain unclear. In this clinical cohort study, including 28 patients with eclampsia and 39 matched healthy controls, fecal samples were collected for 16S rRNA gene sequencing, and serum was collected for targeted metabolomics research. The results showed that the level of TMAO and the abundance of its source bacteria had significantly increased in patients with PE, and were positively correlated with the clinical progression of PE. Fecal microbiota transplantation (FMT) was applied to an antibiotic-depleted-treated mouse model and targeted inhibition of TMAO. The results of the FMT experiment revealed that mice that received fecal microbiota transplantation from patients with PE developed typical PE symptoms and increased oxidative stress and inflammatory damage, both of which were reversed by 3,3-Dimethyl-1-butanol (DMB), a TMAO inhibitor, which also improved pregnancy outcomes in the model mice. Similar results were obtained in the classical NG-Nitroarginine methyl ester (L-NAME) induced PE mouse model. Mechanistically, TMAO promotes the progression of PE by regulating inflammatory and oxidative stress-related signaling pathways, affecting the migration and angiogenesis of vascular endothelial cells, as well as the migration and invasion of trophoblast cells. Our results reveal the role and mechanism of gut microbiota and TMAO in the progression of PE, provides new ideas for exploring the pathogenesis and therapeutic targets of PE, and determines the potential application value of TMAO as a target for PE intervention.

Abstract
Hematologists are often needed to assist with the management of microangiopathic emergencies in pregnancy. A firm understanding of the diagnosis and management of preeclampsia with severe features, hemolysis elevated liver enzyme and low platelet syndrome, and disseminated intravascular coagulation, which are the most common causes of microangiopathic emergencies, is critical. However, being able to consider when other microangiopathic emergencies (acute fatty liver of pregnancy, congenital and acquired thrombotic thrombocytopenic purpura, complement mediated microangiopathy, antiphospholipid syndrome) should be considered is imperative. The hematologist and obstetric team should work together to optimize the care of common as well as rare hematologic emergencies.

Abstract
Endothelial cell damage is an important feature of preeclampsia (PE). Human umbilical mesenchymal stem-cell-derived extracellular vesicles (HUMSCs-derived EVs) have been shown to have therapeutic effects on a variety of diseases and tissue damage. However, the therapeutic effect of HUMSCs-derived EVs on endothelial injury in PE remains unclear. This study explored the possible mechanism of HUMSCs-derived EVs in the treatment of endothelial cell injury. Tumor necrosis factor α- and lipopolysaccharide-induced endothelial dysfunction models were used to evaluate the therapeutic effect of HUMSCs-derived EVs on endothelial injury. We further constructed PE mouse models to explore the function of HUMSCs-derived EVs in vivo. The changes of metabolites in endothelial cells after HUMSCs-derived EVs treatment were analyzed by metabolomics analysis and further validated by cell experiments. HUMSCs-derived EVs treatment can alleviate endothelial cell injury in PE, involving cell proliferation, migration, angiogenesis, and anti-inflammatory. Importantly, administration of HUMSCs-derived EVs improves hypertension and proteinuria in PE mice, alleviates kidney damage, and promotes vascularization in the placenta. Furthermore, metabolomics analysis found that the arginine metabolic pathway is activated after HUMSCs-derived EVs treatment. We also observed increased arginine level, nitric oxide content, and nitric oxide synthase activity, and further experiments proved that activating the arginine metabolic pathway could alleviate endothelial dysfunction. Our results reveal that HUMSCs-derived EVs could ameliorate PE endothelial dysfunction by activating the arginine metabolic pathway and may serve as a therapeutic method for treating PE.

Abstract
BACKGROUND Neonatal complications and deaths are still increasing worldwide. Therefore, this study aimed to assess perinatal outcomes and their determinants among women with eclampsia and severe preeclampsia admitted to selected tertiary hospitals Eastern Ethiopia. METHODS The prospective observational study was conducted among 245 foetal born to women with eclampsia and severe preeclampsia admitted to selected Hospitals. Data were collected from patients' charts and maternal interviews using questionnaires and telephone follow-ups from April 01 to September 30, 2022. Then, Cox regression were used to determine the predictors of perinatal clinical outcomes by SPSS (version 21.0®). Hazard ratios with a two-sided P-value < 0.05 were considered statistically significant. RESULT Of 245 deliveries, perinatal mortality was 26.1 % and about 57.4 % of newborns developed neonatal complications. Fifth-minute Apgar score (AHR: 10.3; 95 % C.I: 3.8-28.1; P: 0.0001) was statistically a determinant to perinatal mortality whereas maternal parity (AHR: 1.7; 95 % CI: 1.0-2.86; P: 0.05), maternal diagnosis (AHR: 2.1; 95 % C.I:1.17-3.66; P: 0.012), maternal complications (AHR: 1.96; 95 % C.I: 1.13-3.41; P: 0.018) and fifth-minute Apgar score (AHR: 2.0; 95 % C.I: 1.29-3.19; P: 0.002) were found to be determinants for neonatal complications. CONCLUSION Despite the inclusion of magnesium sulphate into the national drug list of Ethiopia to reduce maternal and perinatal morbidity and mortality, the perinatal condition remained a severe concern and worse among patients with eclampsia. Interventions to reduce the incidence of eclampsia, better antenatal care, early recognition, prompt treatment of severe preeclampsia, and enhanced neonatal care have to be initiated for patients.

Abstract
AIM Cryoprecipitate (CRYO) is a concentrated preparation of coagulation factors formulated from fresh frozen plasma (FFP), which can replenish coagulation factors rapidly. Preeclampsia (PE) is frequently associated with postpartum hemorrhage (PPH), and the rapid replenishment of coagulation factors is vital in the management. We conducted a retrospective cohort study to determine the efficacy of administering CRYO irrespective of fibrinogen levels in patients with PE who experienced severe PPH. METHODS Patients with PPH accompanied by PE and those who required red blood cell (RBC) transfusion were included. Cases were divided into two groups: those treated with CRYO (N = 16) and those not treated with CRYO (N = 10). The total transfusion volume, blood loss before and after transfusion initiation, duration of hospitalization, presence of pulmonary edema, and performance of either interventional radiology or hysterectomy were compared. RESULTS The median fibrinogen levels before transfusion were 2.24 and 2.34 g/L in the CRYO group and the not using group, respectively. Although blood loss before transfusion was comparable between the two groups, blood loss after transfusion was significantly less in the CRYO group (median: 520 vs. 2352 mL, p = 0.015), as well as the total blood loss (median: 2285 vs. 3825 mL, p = 0.005) and total transfusion volume (median: RBC 6 vs. 16 U, p = 0.01, FFP 10 vs. 20 U, p = 0.017). CONCLUSION Prompt replenishment of coagulation factors using CRYO to patients with PE who experience severe PPH could decrease further bleeding.

Abstract
Early-onset preeclampsia (EOPE) is a severe pregnancy complication associated with defective trophoblast differentiation and functions at implantation, but manifestation of its phenotypes is in late pregnancy. There is no reliable method for early prediction and treatment of EOPE. Adrenomedullin (ADM) is an abundant placental peptide in early pregnancy. Integrated single-cell sequencing and spatial transcriptomics confirm a high ADM expression in the human villous cytotrophoblast and syncytiotrophoblast. The levels of ADM in chorionic villi and serum were lower in first-trimester pregnant women who later developed EOPE than those with normotensive pregnancy. ADM stimulates differentiation of trophoblast stem cells and trophoblast organoids in vitro. In pregnant mice, placenta-specific ADM suppression led to EOPE-like phenotypes. The EOPE-like phenotypes in a mouse PE model were reduced by a placenta-specific nanoparticle-based forced expression of ADM. Our study reveals the roles of trophoblastic ADM in placental development, EOPE pathogenesis, and its potential clinical uses.

Abstract
OBJECTIVE The objective of this study was to compare the frequency and timing of laboratory abnormalities and evaluate optimal laboratory testing strategies in women with preeclampsia (PE) undergoing expectant management. STUDY DESIGN Retrospective cohort study of women with inpatient expectant management of PE at ≥23 weeks at a tertiary center from 2015 to 2018 was conducted. Women ineligible for expectant management or with less than two laboratory sets (platelets, aspartate aminotransferase, and serum creatinine) before the decision to deliver were excluded. Women were categorized as per the American College of Obstetricians and Gynecologists' definitions by initial diagnosis: PE without severe features, superimposed preeclampsia (SiPE) without severe features, and their forms with severe features. The frequency and timing of laboratory abnormalities were compared across the four PE categories. Kaplan-Meier curves modeled time to a laboratory abnormality (event) with censoring for delivery and were compared using log-rank tests. Logistic regression analysis modeled the development of a laboratory abnormality as a function of testing time intervals (days) for each PE type. Receiver operating characteristic curves and areas under the curve (AUC) were calculated; optimal cut points were determined using the Liu method. RESULTS Among 636 women who met inclusion criteria, laboratory abnormalities were uncommon (6.3%). The median time to a laboratory abnormality among all women was ≤10 days, time being shortest in women with PE with severe features. Time to laboratory abnormality development did not differ significantly between the four PE groups (p = 0.36). Laboratory assessment intervals were most predictive for PE and SiPE with severe features (AUC = 0.87, AUC = 0.72). Optimal cutoffs were every 4 days for PE without severe features, 2 days for PE with severe features, 8 days for SiPE without severe features, and 3 days for SiPE with severe features. CONCLUSION Most laboratory abnormalities in PE occur earlier and more frequently in those with severe features. Individual phenotypes should undergo serial evaluation based on this risk stratification. KEY POINTS · Most laboratory abnormalities occur within 10 days of diagnosis.. · Laboratory abnormalities occur more often with severe features.. · Laboratory testing should occur according to disease severity..

Abstract
OBJECTIVE To develop a model for predicting postpartum readmission for hypertension and pre-eclampsia at delivery discharge and assess external validation or model transportability across clinical sites. DESIGN Prediction model using data available in the electronic health record from two clinical sites. SETTING Two tertiary care health systems from the Southern (2014-2015) and Northeastern USA (2017-2019). POPULATION A total of 28 201 postpartum individuals: 10 100 in the South and 18 101 in the Northeast. METHODS An internal-external cross validation (IECV) approach was used to assess external validation or model transportability across the two sites. In IECV, data from each health system were first used to develop and internally validate a prediction model; each model was then externally validated using the other health system. Models were fit using penalised logistic regression, and accuracy was estimated using discrimination (concordance index), calibration curves and decision curves. Internal validation was performed using bootstrapping with bias-corrected performance measures. Decision curve analysis was used to display potential cut points where the model provided net benefit for clinical decision-making. MAIN OUTCOME MEASURES The outcome was postpartum readmission for either hypertension or pre-eclampsia <6 weeks after delivery. RESULTS The postpartum readmission rate for hypertension and pre-eclampsia overall was 0.9% (0.3% and 1.2% by site, respectively). The final model included six variables: age, parity, maximum postpartum diastolic blood pressure, birthweight, pre-eclampsia before discharge and delivery mode (and interaction between pre-eclampsia × delivery mode). Discrimination was adequate at both health systems on internal validation (c-statistic South: 0.88; 95% confidence interval [CI] 0.87-0.89; Northeast: 0.74; 95% CI 0.74-0.74). In IECV, discrimination was inconsistent across sites, with improved discrimination for the Northeastern model on the Southern cohort (c-statistic 0.61 and 0.86, respectively), but calibration was not adequate. Next, model updating was performed using the combined dataset to develop a new model. This final model had adequate discrimination (c-statistic: 0.80, 95% CI 0.80-0.80), moderate calibration (intercept -0.153, slope 0.960, Emax 0.042) and provided superior net benefit at clinical decision-making thresholds between 1% and 7% for interventions preventing readmission. An online calculator is provided here. CONCLUSIONS Postpartum readmission for hypertension and pre-eclampsia may be accurately predicted but further model validation is needed. Model updating using data from multiple sites will be needed before use across clinical settings.

Abstract
The recent publication of the Chronic Hypertension and Pregnancy (CHAP) trial has already changed the management of pregnant people with mild chronic hypertension. However, similar to any new intervention or change in management, we have encountered confusion regarding the management and implementation of the "Treatment for mild chronic hypertension during pregnancy" trial findings. In this clinical opinion, we addressed the aspects relating to the implementation that cannot be gleaned from the manuscript but were part of the trial conduct. Furthermore, we discussed several clinical questions that may affect the management of a patient with chronic hypertension following the "Treatment for mild chronic hypertension during pregnancy" trial and provided suggestions based on our experience and opinion.

Abstract
Preeclampsia is a specific disease during pregnancy and is a significant factor in the increased mortality in perinatal women. Gut microbiota, an intricate and abundant microbial community in the digestive tract, is crucial for host metabolism, immunity, and nutrient absorption. The onset and progression of preeclampsia are closely correlated with the changes in maternal gut microbiota. Research purpose was to compile the existing bits of present scientific data and to close the gap in the knowledge of changes in gut microbiota in preeclampsia and their association with preeclampsia. We searched studies from two electronic databases (PubMed and Web of Science) included from 2014 to 2023. This review is divided into three parts. In the first part, the author elaborates longitudinal differences of maternal gut microbiota during different gestation periods. In the second part, we discuss that gut microbiota can lead to the occurrence of preeclampsia by systemic immune response, influencing the release of active peptides, short-chain fatty acids, trimethylamine-N-oxide (TMAO) and other metabolites, vascular factors and Microorganism-immune axis. In the third part, we proposed that a high-fiber diet combined with drugs and microecological regulators may be therapeutic in enhancing or preventing the emergence and evolution of preeclampsia, which needs further exploration. Although the pathogenesis of preeclampsia is still nebulous and there is no clear and valid clinical treatment, our study provides new ideas for the pathogenesis, prevention and treatment of preeclampsia.

Abstract
Hypertension has been shown to have long-term cardiovascular effects if left untreated. Hypertension also has been shown to affect women during pregnancy, which can be detrimental not only to the patient but also to the fetus. Early identification and treatment are paramount to prevent adverse outcomes. This article details the epidemiology, clinical presentation, diagnosis, and treatment of essential hypertension in women, gestational hypertension, preeclampsia, and eclampsia.

Abstract
INTRODUCTION In low-resource settings, midwives are the first contact for women with preeclampsia and lead the coordination of care. Unfavourable preeclampsia outcomes create a burden for women, families, and the health system. It is therefore important to understand the unique context of midwives' practice and the complex factors that influence the delivery of maternal healthcare. AIM This qualitative study explored the perspectives of key stakeholders in a tertiary hospital in Ghana regarding the facilitators and barriers influencing midwives' provision of preeclampsia care using a socioecological model. METHODS Semi-structured interviews were conducted with 42 participants comprising senior managers (n = 7) and hospital midwives (n = 35) in 2021. Thematic analysis used Braun and Clarke's six-step method, and the findings were organised within four levels of the socioecological model: individual, interpersonal, organisational, and public policy. RESULTS Two main themes were identified: 1) Facilitators of preeclampsia management, and 2) Barriers to preeclampsia management. Facilitators were identified at three levels (individual, interpersonal, and organisational) and included midwives' knowledge of preeclampsia; midwives' self-efficacy; midwives' skillset to enhance preeclampsia care; collaborative practice; and strategies for preeclampsia care quality improvement. At the individual level, the barriers were inadequate pre-service preparation, lack of evidence-based midwifery care, and colleagues' work attitudes. Hierarchical decision-making and staff views of women's risk perceptions were identified as barriers at the interpersonal level. At the organisational level, the barriers were: scarce resources and staff shortages, and a lack of midwifery-specific guidelines. Two barriers were identified within the public policy level: the high cost of preeclampsia care and issues with the referral system. CONCLUSION Multi-faceted factors play a significant role in midwives' management of preeclampsia. Hence context-specific multi-level interventions have the potential to improve the quality-of-care women in Ghana receive.

Abstract
Preeclampsia is the leading cause of maternal-fetal morbidity worldwide. The concept that persistent feto-placental intolerance is important in the pathogenesis of preeclampsia (PreE) has been demonstrated by our lab and others. Arginine vasopressin (AVP) infusion during pregnancy induces cardiovascular, renal, and T helper (TH) cell alterations in mice consistent with human PreE. In addition to their conventional immuno-stimulatory role, dendritic cells (DCs) also play a vital role in immune tolerance. In contrast to conventional DCs, regulatory DCs (DCregs) express low levels of co-stimulatory markers, produce anti-inflammatory cytokines, induce T regulatory (Treg) cells, and promote tolerance. In mice, DCregs prevent pro-inflammatory responses and induce antigen-specific tolerance. Given these known functions of DCregs, we hypothesize that DCregs will prevent the development of AVP-induced PreE in mice. C57BL/6J females were infused with AVP (24 ng/h) or saline throughout gestation via an osmotic minipump. Bone-marrow-derived DCregs were injected into AVP-infused dams at the time of the pump implantation or on gestational day (GD) 7. The blood pressure of the mice was taken throughout their pregnancy. The maternal urine proteins and TH-associated cytokines in maternal and fetal tissues were measured on GD 18. The treatment with DCregs effectively prevented the elevation of maternal blood pressure, proteinuria, and fetal growth restriction that were observed in AVP-infused dams. Furthermore, we noted a reduction in the pro-inflammatory TH-associated cytokines IFNγ and IL-17, while anti-inflammatory cytokines IL-4, IL-10, and TGFβ showed an increase following DCreg treatment. These outcomes provide strong evidence supporting the potential of DCregs as a valuable therapeutic approach in addressing PreE.

Abstract
OBJECTIVES To analyze healthcare resource utilization and severe maternal morbidity (SMM) in Black and White patients with preeclampsia diagnosis versus signs/symptoms. STUDY DESIGN This was a retrospective cohort study analyzing data from the IBM® Explorys Database between 7/31/2012-12/31/2020. Demographic, clinical, and laboratory data were extracted. Healthcare utilization and SMM were analyzed during the antepartum period (20 weeks of gestation until delivery) among Black and White patients with signs/symptoms of preeclampsia, with a diagnosis of preeclampsia, or neither (control). MAIN OUTCOME MEASURES Healthcare utilization and SMM in those with a preeclampsia diagnosis or signs/symptoms of preeclampsia only were compared with a control group (White patients with no preeclampsia diagnosis or signs/symptoms). RESULTS Data from 38,190 Black and 248,568 White patients were analyzed. Patients with preeclampsia diagnosis or signs/symptoms were more likely to visit the emergency room compared to those without diagnosis or signs/symptoms. Black patients with signs/symptoms of preeclampsia had the highest elevated risk (odds ratio [OR] = 3.4), followed by Black patients with a preeclampsia diagnosis (OR = 3.2), White patients with signs/symptoms (OR = 2.2), and White patients with a preeclampsia diagnosis (OR = 1.8). More Black patients experienced SMM (SMM rate 6.1% [Black with preeclampsia diagnosis] and 2.6% [Black with signs/symptoms]) than White patients (5.0% [White with preeclampsia diagnosis] and 2.0% [White with signs/symptoms]). SMM rates were higher for Black preeclampsia patients with severe features than for White preeclampsia patients with severe features (8.9% vs 7.3%). CONCLUSIONS Compared with White patients, Black patients had higher rates of antepartum emergency care and antepartum SMM.

Abstract
Preeclampsia (PE), the most severe presentation of hypertensive disorders of pregnancy, is the major cause of morbidity and mortality linked to pregnancy, affecting both mother and fetus. Despite advances in prophylaxis and managing PE, delivery of the fetus remains the only causative treatment available. Focus on complex pathophysiology brought the potential for new treatment options, and more conservative options allowing reduction of feto-maternal complications and sequelae are being investigated. Endogenous digitalis-like factors, which have been linked to the pathogenesis of preeclampsia since the mid-1980s, have been shown to play a role in the pathogenesis of various cardiovascular diseases, including congestive heart failure and chronic renal disease. Elevated levels of EDLF have been described in pregnancy complicated by hypertensive disorders and are currently being investigated as a therapeutic target in the context of a possible breakthrough in managing preeclampsia. This review summarizes mechanisms implicating EDLFs in the pathogenesis of preeclampsia and evidence for their potential role in treating this doubly life-threatening disease.

Abstract
BACKGROUND Preeclampsia is a unique multisystem disorder that affects 5-8% of pregnancies. A high level of soluble fms-like tyrosine kinase-1 (sFlt-1) is a hallmark of preeclampsia that causes endothelial dysfunction. Exosomes derived from mesenchymal stem cells (MSCs) have been indicated to improve endothelial performances by transporting signals to target cells. We hypothesized that exosomes derived from MSCs have potential effects against preeclampsia. METHODS We collected human umbilical cord MSC-derived exosomes (HUCMSC-exos) by ultracentrifugation. The size and morphology of the exosomes were examined using a transmission electron microscope and nanoparticle tracking analysis. Pregnant mice were injected with murine sFlt-1 adenovirus to build the preeclampsia-like mouse model and then treated with HUCMSC-exos. Human umbilical vein endothelial cells (HUVECs) were infected with lentiviruses expressing tet-on-sFlt-1 to obtain cells overexpressing sFlt-1. Cell proliferation and migration assays were used to measure the endothelial functions. The exosomes enriched proteins underlying mechanisms were explored by proteomic analysis. RESULTS In the current study, we successfully collected the cup-shaped HUCMSC-exos with diameters of 30-150 nm. In the sFlt-1-induced preeclampsia mouse model, HUCMSC-exos exhibited beneficial effects on adverse birth events by decreasing blood pressure and improving fetal birth weight. In addition, preeclamptic dams that were injected with HUCMSC-exos had rebuilt dense placental vascular networks. Furthermore, we observed that HUCMSC-exos partially rescued sFlt-1-induced HUVECs dysfunction in vitro. Proteomics analysis of HUCMSC-exos displayed functional enrichment in biological processes related to vesicle-mediated transport, cell communication, cell migration, and angiogenesis. CONCLUSION We propose that exosomes derived from HUCMSCs contain abundant Versican and play beneficial roles in the birth outcomes of sFlt-1-induced preeclamptic mice by promoting angiogenesis.

Abstract
BACKGROUND Preeclampsia remains one of the most serious complications of pregnancy. Effective therapies are yet to be developed. Recent research has identified an imbalance of angiogenic and antiangiogenic factors as a root cause of preeclampsia. In particular, soluble fms-like tyrosine kinase-1 (sFlt-1) has been shown to bind the angiogenic factors vascular endothelial growth factor (VEGF) and placental growth factor (PlGF), reducing blood vessel growth. Increasing preclinical and clinical evidence suggests that removal of the sFlt-1 protein may benefit patients with early onset preeclampsia. sFlt-1 may be removed by conventional blood purification techniques, such as therapeutic plasma exchange (TPE) and dextran sulfate apheresis (DSA), or emerging technologies, including extracorporeal magnetic blood purification (MBP). METHODS We compare the performance and selectivity of TPE, DSA, and MBP for the therapeutic removal of sFlt-1. For MPB, we employ magnetic nanoparticles functionalized with either sFlt-1 antibodies or the sFlt-1-binding partner, vascular endothelial growth factor (VEGF). RESULTS We demonstrate that sFlt-1 removal by MBP is feasible and significantly more selective than TPE and DSA at comparable sFlt-1 removal efficiencies (MBP 96%, TPE 92%, DSA 78%). During both TPE and DSA, complement factors (incl. C3c and C4) are depleted to a considerable extent (-90% for TPE, -55% for DSA), while in MBP, complement factor concentrations remain unaltered. We further demonstrate that the removal efficacy of sFlt-1 in the MBP approach is strongly dependent on the nanoparticle type and dose and can be optimized to reach clinically feasible throughputs. CONCLUSIONS Taken together, the highly selective removal of sFlt-1 and potential other disease-causing factors by extracorporeal magnetic blood purification may offer new prospects for preeclamptic patients.

Abstract
Atherogenic dyslipidemia-before or during pregnancy-may contribute to preeclampsia and subsequent cardiovascular disease risk. We performed a nested case-control study to further understand dyslipidemia associated with preeclampsia. The cohort consisted of participants in the randomized clinical trial "Improving Reproductive Fitness Through Pretreatment with Lifestyle Modification in Obese Women with Unexplained Infertility" (FIT-PLESE). FIT-PLESE was designed to study the effect of a pre-fertility treatment 16-week randomized lifestyle intervention program (Nutrisystem diet + exercise + orlistat vs. training alone) on improvement in live birth rate among obese women with unexplained infertility. Of the 279 patients in FIT-PLESE, 80 delivered a viable infant. Maternal serum was analyzed across five visits: before and after lifestyle interventions and also at three pregnancy visits (16, 24, and 32 weeks gestation). Apolipoprotein lipids were measured in a blinded fashion using ion mobility. Cases were those who developed preeclampsia. Controls also had a live birth but did not develop preeclampsia. Generalized linear and mixed models with repeated measures were used to compare the mean lipoprotein lipid levels of the two groups across all visits. Complete data were available for 75 pregnancies, and preeclampsia developed in 14.5% of the pregnancies. Cholesterol/high-density lipoprotein (HDL) ratios (p < 0.003), triglycerides (p = 0.012), and triglyceride/HDL ratios, all adjusted for BMI, were worse in patients with preeclampsia (p < 0.001). Subclasses a, b, and c of highly atherogenic, very small, low-density lipoprotein (LDL) particles were higher during pregnancy for the preeclamptic women (p < 0.05). Very small LDL particle subclass d levels were significantly greater only at 24 weeks (p = 0.012). The role of highly atherogenic, very small LDL particle excess in the pathophysiology of preeclampsia awaits further investigation.

Abstract
The aim of this study was to describe maternal characteristics and pregnancy outcomes of women admitted in a dedicated obstetric high care unit (OHCU) in a tertiary hospital in Gauteng province, South Africa. The study involved review of clinical records of women admitted to OHCU between January and June 2016. Data collected included maternal demographic data, indication for admission, management and outcomes. A total of 4 637 of women gave birth and 114 (2.5%) were admitted to the OHCU during this period. Majority (90, 78.9%) were younger than 35 (mean 29.6) years with 32(28.1%), in their first pregnancy. Obstetric related indications for OHCU admission were mainly, pre-eclampsia and related complications (89, 78.1%), followed by obstetric haemorrhage (32, 28.1%). Cardiac disease, 14(12.3%) and pneumonia 6(5.3%) were the most common non-obstetrics indications for admission. Majority of patients stayed in OHCU for an average of 24-48 hours and were discharged alive (99.86.8%). Only 11(9.6%) were transferred to ICU and complications related to cardiac diseases were the most common reason for the transfer. Preeclampsia, obstetric hemorrhage and cardiac related complications are the most common reasons for OHCU and ICU admissions however most of these condition can be successfully managed in OHCU.

Abstract
PURPOSE OF REVIEW This review will summarize recent findings relating to the diagnostic approach to preeclampsia and current avenues of research aimed at modifying the underlying disease process. RECENT FINDINGS Growing international consensus supports a broad preeclampsia definition that incorporates maternal end-organ and uteroplacental dysfunction. Recent evidence demonstrates that this definition better identifies women and babies at risk of adverse outcomes compared to the traditional definition of hypertension and proteinuria. Multiple studies have demonstrated the usefulness and cost-effectiveness of angiogenic biomarkers such as soluble fms-like tyrosine kinase-1 and placental growth factor as a clinical adjunct to diagnose and predict severity of preeclampsia associated outcomes. Current novel therapeutic approaches to preeclampsia target pathogenic pathways (e.g. antiangiogenesis) or downstream effects such as oxidative stress and nitric oxide. Recent findings relating to these promising candidates are discussed. Multicenter clinical trials are needed to evaluate their effectiveness and ability to improve fetal and maternal outcomes. SUMMARY We provide an updated framework of the current approaches to define and diagnose preeclampsia. Disease modifying therapies (in particular, targeting the angiogenic pathway) are being developed for the first time and promise to revolutionize the way we manage preeclampsia.

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 Failures in invasive extravillous trophoblasts (EVTs) migration into the maternal uterus have been noticed in preeclampsia (PE). Human umbilical cord mesenchymal stem cell (hUCMSC)-derived extracellular vesicles (EVs) have been highlighted for the role as a potential therapeutic method in PE. This study intends to investigate the mechanistic basis of hUCMSCs-derived EVs loaded with bioinformatically identified TFCP2 in the activities of EVTs of PE. METHODS Primary human EVTs were exposed to hypoxic/reoxygenation (H/R) to mimic the environment encountered in PE. The in vivo PE-like phenotypes were induced in mice by reduced uterine perfusion pressure (RUPP) surgery. CCK-8, Transwell and flow cytometry assays were performed to detect proliferation, migration, invasion and apoptosis of H/R-exposed EVTs. More importantly, EVs were extracted from hUCMSCs and transduced with ectopically expressed TFCP2, followed by co-culture with EVTs. RESULTS TFCP2 was found to be down-regulated in the preeclamptic placental tissues and in H/R-exposed EVTs. hUCMSCs-EVs loaded with TFCP2 activated the Wnt/β-catenin pathway, thereby promoting the proliferative, migratory, and invasive potential of EVTs. Furthermore, overexpression of TFCP2 alleviated PE-like phenotypes in mice, which was associated with activated Wnt/β-catenin pathway. CONCLUSION From our data we conclude that hUCMSCs-EVs overexpressing TFCP2 may be instrumental for the therapeutic targeting and clinical management of PE.

Abstract
Two important maternal cardiometabolic disorders (CMDs), hypertensive disorders in pregnancy (HDP) (including pre-eclampsia) and gestational diabetes mellitus (GDM), result in a large disease burden for pregnant individuals worldwide. A global consensus has not been reached about the diagnostic criteria for HDP and GDM, making it challenging to assess differences in their disease burden between countries and areas. However, both diseases show an unevenly distributed disease burden for regions with a low income or middle income, or low-income and middle-income countries (LMICs), or regions with lower sociodemographic and human development indexes. In addition to many common clinical, demographic and behavioural risk factors, the development and clinical consequences of maternal CMDs are substantially influenced by the social determinants of health, such as systemic marginalization. Although progress has been occurring in the early screening and management of HDP and GDM, the accuracy and long-term effects of such screening and management programmes are still under investigation. In addition to pharmacological therapies and lifestyle modifications at the individual level, a multilevel approach in conjunction with multisector partnership should be adopted to tackle the public health issues and health inequity resulting from maternal CMDs. The current COVID-19 pandemic has disrupted health service delivery, with women with maternal CMDs being particularly vulnerable to this public health crisis.

Abstract
Pre-eclampsia (PE), associated with placental malperfusion, is the primary reason for maternal and perinatal mortality and morbidity that can cause vascular endothelial injury and multi-organ injury. Despite considerable research efforts, no pharmaceutical has been shown to stop disease progression. If women precisely diagnosed with PE can achieve treatment at early gestation, the maternal and fetal outcomes can be maximally optimized by expectant management. Current diagnostic approaches applying maternal characteristics or biophysical markers, including blood test, urine analysis and biophysical profile, possess limitations in the precise diagnosis of PE. Biochemical factor research associated with PE development has generated ambitious diagnostic targets based on PE pathogenesis and dissecting molecular phenotypes. This review focuses on current developments in biochemical prediction of PE and the corresponding interventions to ameliorate disease progression, aiming to provide references for clinical diagnoses and treatments.

Abstract
Preeclampsia (PE) is a common pregnancy-specific disorder that is a major cause of both maternal and fetal morbidity and mortality. Central to the pathogenesis of PE is the production of antiangiogenic and inflammatory factors by the hypoxic placenta, leading to the downstream manifestations of the disease, including hypertension and end-organ damage. Currently, effective treatments are limited for PE; however, the development of preclinical animal models has helped in the development and evaluation of new therapeutics. In this review, we will summarize some of the more commonly used models of PE and highlight their similarities to the human syndrome, as well as the therapeutics tested in each model.

Abstract
Objective Preeclampsia is a common and serious complication of pregnancy, posing a threat to maternal and fetal safety due to the lack of effective biomarkers and treatment strategies. This study aimed to identify potential biomarkers that can be used to predict preeclampsia and identify the molecular mechanisms of preeclampsia pathogenesis and drug prediction at the transcriptome level. Methods We analyzed differential expression genes (DEGs) in preeclampsia and non-preeclampsia groups in the GSE75010 dataset, cross-linking with extracted inflammatory response-related genes to obtain differentially expressed inflammation-related genes (DINRGs). Enrichment analysis and protein-protein interaction (PPI) networks were constructed to understand the functions and enrichment pathways. Machine learning models were used to identify key genes associated with preeclampsia and build a nomogram in the training set, which was validated in the validation set. The R package RcisTarget was used to predict transcription factors, and Cytoscape was used to construct miRNA-mRNA pathways, which could identify the molecular mechanisms. Then, we conducted molecular docking of the obtained key genes INHBA (inhibin subunit beta A), OPRK1 (opioid receptor kappa 1), and TPBG (trophoblast glycoprotein), as well as predicted transcription factors with drug molecules. Additionally, the CIBERSORT method explored the differences in immune cell infiltration between preeclampsia and non-preeclampsia samples based on the GSE75010 dataset. Results A total of 69 DINRGs associated with preeclampsia patients were screened. INHBA, OPRK1, and TPBG were the key genes based on machine learning models. A nomogram for prediction was further constructed, and the receiver operating curves (ROCs) showed good performance. Based on the transcriptome level of key genes, we proposed that RELA-miR-548K/miR-1206-TPBG may be a potential RNA regulatory pathway regulating the progression of early preeclampsia. Molecular docking suggested the effectiveness of curcumin in the treatment of preeclampsia. Additionally, regulatory T cells (Tregs) and resting mast cells were significantly different between the two groups. Conclusion In summary, we identified three key inflammation-associated genes, namely INHBA, OPRK1, and TPBG, which can be used as potential genetic biomarkers for preeclampsia prediction and treatment, and established a nomogram as a predictive model. Additionally, we provided insights into the mechanisms of preeclampsia development at the transcriptome level and performed corresponding drug predictions.

Abstract
BACKGROUND Electronic health record (EHR)-based clinical decision support tools can improve the use of evidence-based clinical guidelines for preeclampsia management that can reduce maternal mortality and morbidity. No study has investigated the organizational capabilities that enable hospitals to use EHR-based decision support tools to manage preeclampsia. OBJECTIVE To examine the association of organizational capabilities and hospital adoption of EHR-based decision support tools for preeclampsia management. METHODS Cross-sectional analyses of hospitals providing obstetric care in 2017. In total, 739 hospitals responded to the 2017-2018 National Survey of Healthcare Organizations and Systems (NSHOS) and were linked to the 2017 American Hospital Association (AHA) Annual Survey Database and the Area Health Resources File (AHRF). A total of 425 hospitals providing obstetric care across 49 states were included in the analysis. The main outcome was whether a hospital adopted EHR-based clinical decision support tools for preeclampsia management. Hospital organizational capabilities assessed as predictors include EHR functions, adoption of evidence-based clinical treatments, use of quality improvement methods, and dissemination processes to share best patient care practices. Logistic regression estimated the association of hospital organizational capabilities and hospital adoption of EHR-based decision support tools to manage preeclampsia, controlling for hospital structural and patient sociodemographic characteristics. RESULTS Two-thirds of the hospitals (68%) adopted EHR-based decision support tools for preeclampsia, and slightly more than half (56%) of hospitals had a single EHR system. Multivariable regression results indicate that hospitals with a single EHR system were more likely to adopt EHR-based decision support tools for preeclampsia (17.4 percentage points; 95% CI, 1.9 to 33.0; P < .05) than hospitals with a mixture of EHR and paper-based systems. Compared with hospitals having multiple EHRs, on average, hospitals having a single EHR were also more likely to adopt the tools by 9.3 percentage points, but the difference was not statistically significant (95% CI, -1.3 to 19.9). Hospitals with more processes to aid dissemination of best patient care practices were also more likely to adopt EHR-based decision-support tools for preeclampsia (0.4 percentage points; 95% CI, 0.1 to 0.6, for every 1-unit increase in dissemination processes; P < .01). CONCLUSION Standardized EHRs and policies to disseminate evidence are foundational hospital capabilities that can help advance the use of EHR-based decision support tools for preeclampsia management in the approximately one-third of US hospitals that still do not use them.

Abstract
Objective: To explore the impact of different referral timing on postponing early-onset pre-eclampsia (PE), postponing severe pre-eclampsia (SPE), reducing SPE severe complications and improving maternal and neonatal outcomes by analyzing the pregnancy outcomes of SPE patients who were referred from primary hospitals to tertiary referral center in the referral system. Methods: The clinical data of 159 SPE patients who were referred from primary hospitals, treated and then terminated their pregnancy in Peking University Third Hospital from January 2020 to October 2021, were observed and analyzed in this clinical observational study. According to the clinical stage of PE at the time of referral, they were divided into four groups: 38 cases were referred after onset of SPE severe complications (SPE-C group), 72 cases were referred after onset of SPE (a-SPE group), 15 cases were referred after onset of PE (a-PE group) and 34 cases were referred after detection of PE early warning-signs (Warn-s group). And then these 159 cases were divided into different color groups according to the project management system for high-risk pregnant women. Patients of Red color (highest risk) and Orange color (higher risk) were required to be referred to tertiary hospitals (Red-Orange group, 113 cases), and patients of Yellow color (high risk) could be treated under tertiary hospitals (Yellow group, 46 cases). The maternal and neonatal outcomes of different referral timings were analyzed and compared. Results: (1) Pregnancy outcomes of different referral timings grouped by PE clinical stage at the time of referral: the later the referral timing, the higher the rate of SPE severe complications, the shorter the interval from referral to termination of pregnancy. The rate of SPE severe complications in the SPE-C group was significantly higher than those of the other three groups, and the interval from referral to termination of pregnancy in the SPE-C group was significantly shorter than those of the other three groups (all P<0.05). The referral gestational age of Warn-s group was earlier than those of the other three groups (all P<0.05). The average gestational ages for onset of SPE, termination of pregnancy, and onset of SPE severe complications were all after 34 gestational weeks, and were later than those of a-SPE group and SPE-C group; the rates of SPE onset before 34 gestational weeks, SPE severe complications onset before 34 gestational weeks, terminating pregnancy before 34 gestational weeks, neonatal intensive care unit (NICU) hospitalization, and pregnancy giving up before 28 gestational weeks were lower than those of a-SPE group and SPE-C group, the length of NICU stay was shorter than those of a-SPE group and SPE-C group, and its rate of take-home-babies was 100%, significantly higher than those in a-SPE group and SPE-C group (all P<0.05). The gestational ages for onset of SPE and termination of pregnancy in a-PE group were later than those in a-SPE group and SPE-C group, the rates of SPE onset before 34 gestational weeks, terminating pregnancy before 34 gestational weeks, and NICU hospitalization were lower than those of a-SPE group and SPE-C group, the length of NICU stay was shorter than those of a-SPE group and SPE-C group (all P<0.05). (2) Pregnancy outcomes of different referral timings grouped by the color classification of PE clinical characteristics: among the 159 cases of SPE, 113 cases (71.1%, 113/159) were in the Red-Orange group which were required to be referred to tertiary hospitals, and 46 cases (28.9%, 46/159) were in the Yellow group,which were not in the range of referral requirements, but actually referred to the tertiary hospital and eventually developed SPE. Gestational ages for onset of SPE, termination of pregnancy, and onset of SPE severe complications in the Yellow group were later than those of the Red-Orange group, while the rates of SPE onset before 34 gestational weeks, SPE severe complications onset before 34 gestational weeks, terminating pregnancy before 34 gestational weeks, NICU hospitalization, and pregnancy giving up before 28 gestational weeks were lower than those of the Red-Orange group, the length of NICU stay was shorter than that of the Red-Orange group, and its rate of take-home-babies was higher than that in the Red-Orange group (all P<0.05). (3) Analysis of different clinical referral timings in the Yellow group: among these 159 SPE patients, 46 cases (28.9%, 46/159) would be excluded from the range of referral requirements which belonged to the Yellow color grade, but 6 cases still developed SPE severe complications (4 cases in Warn-s group and 2 cases in a-PE group), 17 cases were terminated pregnancy before 34 weeks of gestation (12 cases in Warn-s group and 5 cases in a-PE group), and 23 cases developed SPE before 34 weeks of gestation (17 cases in Warn-s group and 6 cases in a-PE group). (4) Multivariate analysis: referral after detection of PE early warning signs was the independent protective factor for postponing the onset of SPE severe complications (P<0.05). Referral after detection of PE early warning signs and referral after onset of PE were both protective factors for postponing the onset of SPE and early-onset PE (all P<0.05). Conclusions: Different referral timing in the referral system is one of the key points that affect the maternal and neonatal outcomes of SPE. Referral after detection of PE early warning signs and timely referral after onset of PE would reduce early-onset PE, postpone the onset of SPE and reduce the severe complications of SPE. The clinical development and evolution of PE is really complicated, and referral based on specific clinical situations is better than referral based on fixed mode.

Abstract
Postpartum patients may present to the emergency department with complaints ranging from minor issues, requiring only patient education and reassurance, to severe, life-threatening complications that require prompt diagnosis and multidisciplinary consultation and management. At times, vague presentations or overlapping conditions can make it difficult for the emergency clinician to recognize an emergent condition and initiate proper treatment. This issue reviews the major common emergencies that present in postpartum patients, by chief complaint, including hemorrhage, infection, pre-eclampsia, eclampsia, headache, and cardiopulmonary conditions, and reviews the most recent evidence and guidelines.

Abstract
Animal models have been critical in investigating the pathogenesis, mediators, and even therapeutic options for a number of diseases, including preeclampsia. Preeclampsia is the leading cause of maternal and fetal morbidity and mortality worldwide. The placenta is thought to play a central role in the pathogenesis of this disease because it releases antiangiogenic and proinflammatory factors into the maternal circulation, resulting in the maternal syndrome. Despite the deleterious effects preeclampsia has been shown to have on the mother and baby during pregnancy and postpartum, there is still no effective treatment for this disease. Although clinical studies in patients are crucial to identify the involvement of pathogenic factors in preeclampsia, there are obvious limitations that prevent detailed investigation of the quantitative importance of time-dependent mechanisms involved in this syndrome. Animal models allow investigators to perform proof-of-concept studies and examine whether certain factors found in women with preeclampsia mediate hypertension and other manifestations of this disease. In this brief review, we summarize some of the more widely studied models used to investigate pathophysiological mechanisms that are thought to be involved in preeclampsia. These include models of placental ischemia, angiogenic imbalance, and maternal immune activation. Infusion of preeclampsia-related factors into animals has been widely studied to understand the specific mediators of this disease. These models have been included, in addition to a number of genetic models involved in overexpression of the renin-angiotensin system, complement activation, and trophoblast differentiation. Together, these models cover multiple mechanisms of preeclampsia from trophoblast dysfunction and impaired placental vascularization to the excess circulating placental factors and clinical manifestation of this disease. Most animal studies have been performed in rats and mice; however, we have also incorporated nonhuman primate models in this review. Preclinical animal models not only have been instrumental in understanding the pathophysiology of preeclampsia but also continue to be important tools in the search for novel therapeutic options for the treatment of this disease.

Abstract
This study is aimed at discussing the value of ultrasonic image features in diagnosis of perinatal outcomes of severe preeclampsia on account of deep learning algorithm. 140 pregnant women singleton with severe preeclampsia were selected as the observation group. At the same time, 140 normal singleton pregnant women were selected as the control group. The hemodynamic indexes were detected by color Doppler ultrasound. The CNN algorithm was used to classify ultrasound images of two groups of pregnant women. The differential scanning calorimetry (DSC), mean pixel accuracy (MPA), and mean intersection of union (MIOU) values of CNN algorithm were 0.9410, 0.9228, and 0.8968, respectively. Accuracy, precision, recall, and F1-score were 93.44%, 95.13%, 95.09%, and 94.87%, respectively. The differences were statistically significant (P < 0.05). Compared with the normal control group, the umbilical artery (UA), uterine artery-systolic/diastolic (UTA-S/D), uterine artery (UTA), and digital video (DV) of pregnant women in the observation group were remarkably increased; the minimum alveolar effective concentration (MCA) of the observation group was obviously lower than the MCA of the control group, and the differences between groups were statistically valid (P < 0.05). Logistic regression analysis showed that UA-S/D, UA-resistance index (UA-RI), UTA-S/D, UTA-pulsatility index (UTA-PI), DV-peak velocity index for veins (DV-PVIV), and MCA-S/D were independent risk factors for the outcome of perinatal children with severe preeclampsia. In the perinatal management of severe epilepsy, the combination of the above blood flow indexes to select the appropriate delivery time had positive significance to improve the pregnancy outcome and reduce the perinatal mortality.

Abstract
BACKGROUND Preeclampsia (PE) is one of the leading causes of mortality and complications during pregnancy. It seems that usual prenatal care is not enough for these patients. They require more assistance, support, and guidance from health professionals, and home care is an effective strategy in this regard. Also, Iran has no official or compiled program for home care in high-risk pregnancy. This study was designed to explore the potential achievements and barriers of home care for mothers with PE. METHODS In this qualitative study with conventional content analysis, twenty-eight participants (mothers with PE, maternal health policy-makers, and health care providers) were selected through purposeful sampling with maximum variation. Data were collected through semi-structured interviews until saturation was achieved. Simultaneously, data analysis was performed using MXQDA software. Finally, the main categories were extracted. RESULTS Seven main categories were extracted. Three main categories for the potential achievement included "family involvement in maternal care", "holistic maternal health promotion", and "improving utility of services". The other four categories emerged for barriers included: "more willingness to provide in-hospital medical care", "clients' concerns about cultural issues", "providers` unwillingness to delivery home care", and "insufficiency of infrastructures for home care". CONCLUSION Paying attention to home care advantages, based on the socio-cultural context of the community, making effort to remove the barriers, and organizing home care infrastructures contribute to improvement in the quality of care in women with PE.

Abstract
OBJECTIVE To provide national guidelines for the management of women with severe pre-eclampsia. DESIGN A consensus committee of 26 experts was formed. A formal conflict-of-interest (COI) policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasised. METHODS The last SFAR and CNGOF guidelines on the management of women with severe pre-eclampsia were published in 2009. The literature is now sufficient for an update. The aim of this expert panel guidelines is to evaluate the impact of different aspects of the management of women with severe preeclampsia on maternal and neonatal morbidities separately. The experts studied questions within 7 domains. Each question was formulated according to the PICO (Patients Intervention Comparison Outcome) model and the evidence profiles were produced. An extensive literature review and recommendations were carried out and analysed according to the GRADE® methodology. RESULTS The SFAR/CNGOF experts panel provided 25 recommendations: 8 have a high level of evidence (GRADE 1+/-), 9 have a moderate level of evidence (GRADE 2+/-), and for 7 recommendations, the GRADE method could not be applied, resulting in expert opinions. No recommendation was provided for 3 questions. After one scoring round, strong agreement was reached between the experts for all the recommendations. CONCLUSIONS There was strong agreement among experts who made 25 recommendations to improve practices for the management of women with severe pre-eclampsia.

Abstract
Proteinuria can range from subnephrotic to nephrotic amounts during pregnancy, though nephrotic syndrome (NS) is rare (0.012%-0.025%). Without a renal biopsy, this distinction may be difficult at times. The objective of our study was assessing about renal and feto-maternal outcomes of these patients. This study was done in a tertiary-care hospital in north India from 2010 to 2019. We included all pregnant women with nephrotic-range proteinuria, with no signs or symptoms suggestive of pre-eclampsia. We studied their treatment modalities, renal, maternal, and fetal outcomes. Eighteen eligible pregnant women diagnosed with NS with no features suggestive of pre-eclampsia or associated comorbidities were included. The gestational age of presentation was 23.2 ± 1.36 weeks. The average proteinuria was 4.38 ± 0.76 g/day. The patients were managed conservatively without kidney biopsy. About 16.7% of pregnancies had worsening of hypertension and acute kidney injury which recovered after delivery. Anasarca was troublesome for four patients requiring fresh-frozen plasma infusion. All were managed conservatively; however, five patients were started on empirical immunosuppression, all five with steroids, while two required the addition of calcineurin inhibitors as well. All had live births, but 25.7% each had preterm and intrauterine growth restriction while one required neonatal intensive care unit admission. The degree of proteinuria had an impact on maternal and fetal outcomes, especially on risk to pre-eclampsia. NS during pregnancy needs evaluation and counseling. Majority of them can be managed conservatively yet specific therapies can safely be tried among symptomatic ones. Despite good outcomes, a sizeable risk to maternal and fetal complications can occur.

Abstract
BACKGROUND Pregnancy-induced hypertension (PIH) is a leading cause of maternal and fetal morbidity and mortality. Although case management programs have been proposed to improve maternal and fetal outcomes in high-risk pregnancies, limited data are available regarding the effect of case management on women with PIH. PURPOSE The aim of this study was to evaluate the effect of an antepartum case management program on stress, anxiety, and pregnancy outcomes in women with PIH. METHODS A quasi-experimental research design was employed. A convenience sample of women diagnosed with PIH, including preeclampsia, was recruited from outpatient clinics at a medical center in southern Taiwan. Sixty-two women were assigned randomly to either the experimental group (n = 31) or the control group (n = 31). The experimental group received case management for 8 weeks, and the control group received routine clinical care. Descriptive statistics, independent t or Mann-Whitney U tests, chi-square or Fisher's exact tests, paired t test, and generalized estimating equations were used to analyze the data. RESULTS The average age of the participants was 35.1 years (SD = 4.5). No significant demographic or clinical differences were found between the control and experimental groups. The results of the generalized estimating equations showed significantly larger decreases in stress and anxiety in the experimental group than in the control group. No significant differences were identified between the two groups with respect to infant birth weeks, infant birth weight, average number of medical visits, or frequency of hospitalization. CONCLUSIONS/IMPLICATIONS FOR PRACTICE The nurse-led case management program was shown to have short-term positive effects on the psychosocial outcomes of a population of Taiwanese patients with PIH. These results have important clinical implications for the healthcare administered to pregnant women, particularly in terms of improving the outcomes in those with PIH.

Abstract
The management of hypertensive disease of pregnancy presents an ongoing challenge after patients are discharged from delivery hospitalizations. Preeclampsia and other forms of postpartum hypertension increase the risk for severe maternal morbidity and mortality in the postpartum period, and both hypertension and its associated adverse events disproportionately affect black women. With its ability to transcend barriers to health care access, telemedicine can facilitate high-quality postpartum care delivery for preeclampsia management and thereby reduce racial disparities in obstetric care and outcomes. Here we discuss racial disparities in preeclampsia and the challenge of providing equitable postpartum preeclampsia care. We then describe the utility of novel telemedicine platforms and their application to combat these disparities in preeclampsia care.

Abstract
PROBLEM The Reduced Uterine Perfusion Pressure (RUPP) rat model of placental ischemia recapitulates many characteristics of preeclampsia including maternal hypertension, intrauterine growth restriction (IUGR), and increased cytolytic natural killer cells (cNKs). While we have previously shown a 5-fold higher cytotoxicity of RUPP NKs versus normal pregnant NKs, their role in RUPP pathophysiology remains unclear. In this study, we tested the hypotheses that (1) adoptive transfer of RUPP-stimulated NKs will induce maternal hypertension and IUGR in normal pregnant control (Sham) rats and (2) adoptive transfer of Sham NKs will attenuate maternal hypertension and IUGR in RUPP rats. METHOD OF STUDY On gestation day (GD)14, vehicle or 5 × 106 RUPP NKs were infused i.v. into a subset of Sham rats (Sham+RUPP NK), and vehicle or 5 × 106 Sham NKs were infused i.v. into a subset of RUPP rats (RUPP+Sham NK; n = 12/group). On GD18, Uterine Artery Resistance Index (UARI) was measured. On GD19, mean arterial pressure (MAP) was measured, animals were sacrificed, and blood and tissues were collected for analysis. RESULTS Adoptive transfer of RUPP NKs into Sham rats resulted in elevated NK activation, UARI, placental oxidative stress, and preproendothelin expression as well as reduced circulating nitrate/nitrite. This led to maternal hypertension and IUGR. RUPP recipients of Sham NKs demonstrated normalized NK activation, sFlt-1, circulating and placental VEGF, and UARI, which led to improved maternal blood pressure and normal fetal growth. CONCLUSION These data suggest a direct role for cNKs in causing preeclampsia pathophysiology and a role for normal NKs to improve maternal outcomes and IUGR during late gestation.

Abstract
Background Globally, 292,982 women die due to the complications of pregnancy and
childbirth per year, out of those deaths 85% occurs in Sub Saharan Africa.
In Ethiopia, pre-eclampsia accounts for 11% of direct maternal deaths. Objective To determine maternal and foetal outcomes of pregnancy-induced hypertension
among women who gave birth at health facilities in Hossana town
administration. Methods Institutional based unmatched case-control study was conducted among women,
who gave birth at health facilities from May 20 to October 30, 2018. By
using Epi-Info version 7; 207 sample size was estimated, for each case two
controls were selected. Two health facilities were selected using a simple
random sampling method. Sample sizes for each facility were allocated
proportionally. All cleaned & coded data were entered into Epi-info
version 3.5.1 and analysis was carried out using SPSS version 20.
Multivariate analysis was performed to determine predictors of
pregnancy-induced hypertension at a p-value of <0.05. Result Women between 18 to 41 years old had participated in the study with the mean
age of 26.00(SD ±4.42), and 25.87(SD ±5.02) for cases and controls
respectively. Out of participants 21(30.4%) among cases and 21(15.2%) among
controls had developed at least one complication following delivery. 12
(17.4%) and 8 (5.7%) foetal deaths were found in cases and controls groups
respectively whereas 15.6% from cases and 3.6% from controls groups women
gave birth to the foetus with intra-uterine growth retardation. Women
gravidity AOR = 0.32 [95% CI (0.12 0.86)], Previous history of
pregnancy-induced hypertension AOR = 22.50 [95% CI (14.95 16.52)] and
educational status AOR = 0.32[95% CI (0.12, 0.85)] were identified as
predictor of pregnancy-induced hypertension. Conclusion Women with a previous history of pregnancy-induced hypertension had increased
risk of developing pregnancy-induced hypertension, whilst ≥ 3 previous
pregnancies and informal educational status decrease odds of developing
pregnancy-induced hypertension.
