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.

Adoptive transfer of placental ischemia-stimulated natural killer cells causes a preeclampsia-like phenotype in pregnant rats. Am J Reprod Immunol 2021; 85:e13386. [PMID: 33315281 PMCID: PMC8131208 DOI: 10.1111/aji.13386] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 10/21/2020] [Accepted: 12/09/2020] [Indexed: 12/14/2022] Open
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.

Abstract
The pathophysiology of preeclampsia (PE) is poorly understood; however, there is a large body of evidence that suggests a role of immune cells in the development of PE. Amongst these, B cells are a dominant element in the pathogenesis of PE, and they have been shown to play an important role in various immune-mediated diseases, both as pro-inflammatory and regulatory cells. Perinatal cells are defined as cells from birth-associated tissues isolated from term placentas and fetal annexes and more specifically from the amniotic membrane, chorionic membrane, chorionic villi, umbilical cord (including Wharton's jelly), the basal plate, and the amniotic fluid. They have drawn particular attention in recent years due to their ability to modulate several aspects of immunity, making them promising candidates for the prevention and treatment of various immune-mediated diseases. In this review we describe main findings regarding the multifaceted in vitro and in vivo immunomodulatory properties of perinatal cells, with a focus on B lymphocytes. Indeed, we discuss evidence on the ability of perinatal cells to inhibit B cell proliferation, impair B cell differentiation, and promote regulatory B cell formation. Therefore, the findings discussed herein unveil the possibility to modulate B cell activation and function by exploiting perinatal immunomodulatory properties, thus possibly representing a novel therapeutic strategy in PE.

Abstract
The objective of this literature review was to explore the long-term cardiovascular effects of preeclampsia in women. The primary goal was to determine which organs were most commonly affected in this population. Although it was previously believed that preeclampsia is cured after the delivery of the fetus and the placenta current evidence supports an association between preeclampsia and cardiovascular disease later in life, many years after the manifestation of this hypertensive pregnancy related disorder. Therefore preeclampsia may be emerging as a novel cardiovascular risk factor for women, which requires long-term follow up.

Abstract
CONTEXT Preeclampsia is a leading cardiovascular complication in pregnancy lacking effective diagnostic and treatment strategies. OBJECTIVE To investigate the diagnostic and therapeutic target potential of the angiogenesis proteins, FK506-binding protein like (FKBPL) and CD44. DESIGN AND INTERVENTION FKBPL and CD44 plasma concentration or placental expression were determined in women pre- or postdiagnosis of preeclampsia. Trophoblast and endothelial cell function was assessed following mesenchymal stem cell (MSC) treatment and in the context of FKBPL signaling. SETTINGS AND PARTICIPANTS Human samples prediagnosis (15 and 20 weeks of gestation; n ≥ 57), or postdiagnosis (n = 18 for plasma; n = 4 for placenta) of preeclampsia were used to determine FKBPL and CD44 levels, compared to healthy controls. Trophoblast or endothelial cells were exposed to low/high oxygen, and treated with MSC-conditioned media (MSC-CM) or a FKBPL overexpression plasmid. MAIN OUTCOME MEASURES Preeclampsia risk stratification and diagnostic potential of FKBPL and CD44 were investigated. MSC treatment effects and FKBPL-CD44 signaling in trophoblast and endothelial cells were assessed. RESULTS The CD44/FKBPL ratio was reduced in placenta and plasma following clinical diagnosis of preeclampsia. At 20 weeks of gestation, a high plasma CD44/FKBPL ratio was independently associated with the 2.3-fold increased risk of preeclampsia (odds ratio = 2.3, 95% confidence interval [CI] 1.03-5.23, P = 0.04). In combination with high mean arterial blood pressure (>82.5 mmHg), the risk further increased to 3.9-fold (95% CI 1.30-11.84, P = 0.016). Both hypoxia and MSC-based therapy inhibited FKBPL-CD44 signaling, enhancing cell angiogenesis. CONCLUSIONS The FKBPL-CD44 pathway appears to have a central role in the pathogenesis of preeclampsia, showing promising utilities for early diagnostic and therapeutic purposes.

Abstract
OBJECTIVE To develop a core outcome set for pre-eclampsia. DESIGN Consensus development study. SETTING International. POPULATION Two hundred and eight-one healthcare professionals, 41 researchers and 110 patients, representing 56 countries, participated. METHODS Modified Delphi method and Modified Nominal Group Technique. RESULTS A long-list of 116 potential core outcomes was developed by combining the outcomes reported in 79 pre-eclampsia trials with those derived from thematic analysis of 30 in-depth interviews of women with lived experience of pre-eclampsia. Forty-seven consensus outcomes were identified from the Delphi process following which 14 maternal and eight offspring core outcomes were agreed at the consensus development meeting. Maternal core outcomes: death, eclampsia, stroke, cortical blindness, retinal detachment, pulmonary oedema, acute kidney injury, liver haematoma or rupture, abruption, postpartum haemorrhage, raised liver enzymes, low platelets, admission to intensive care required, and intubation and ventilation. Offspring core outcomes: stillbirth, gestational age at delivery, birthweight, small-for-gestational-age, neonatal mortality, seizures, admission to neonatal unit required and respiratory support. CONCLUSIONS The core outcome set for pre-eclampsia should underpin future randomised trials and systematic reviews. Such implementation should ensure that future research holds the necessary reach and relevance to inform clinical practice, enhance women's care and improve the outcomes of pregnant women and their babies.

Abstract
BACKGROUND Preeclampsia/eclampsia is a major cause of maternal morbidity and mortality worldwide, yet patients' perspectives about their diagnosis are not well understood. Our study examines patient knowledge among women with preeclampsia/eclampsia in a large urban hospital in Ghana. METHODS Postpartum women diagnosed with preeclampsia or eclampsia were asked to complete a survey 2-5 days after delivery that assessed demographic information, key obstetric factors, and questions regarding provider counseling. Provider counseling on diagnosis, causes, complications, and future health effects of preeclampsia/eclampsia was quantified on a 4-point scale ('Counseling Composite Score'). Participants also completed an objective knowledge assessment regarding preeclampsia/eclampsia, scored from 0 to 22 points ('Preeclampsia/Eclampsia Knowledge Score' (PEKS)). Linear regression was used to identify predictors of knowledge score. RESULTS A total of 150 participants were recruited, 88.7% (133) with preeclampsia and 11.3% (17) with eclampsia. Participants had a median age of 32 years, median parity of 2, and mean number of 5.4 antenatal visits. Approximately half of participants reported primary education as their highest level of education. While 74% of women reported having a complication during pregnancy, only 32% of participants with preeclampsia were able to correctly identify their diagnosis, and no participants diagnosed with eclampsia could correctly identify their diagnosis. Thirty-one percent of participants reported receiving no counseling from providers, and only 11% received counseling in all four categories. Even when counseled, 40-50% of participants reported incomplete understanding. Out of 22 possible points on a cumulative knowledge assessment scale, participants had a mean score of 12.9 ± 0.38. Adjusting for age, parity, and the number of antenatal visits, higher scores on the knowledge assessment are associated with more provider counseling (β 1.4, SE 0.3, p < 0.001) and higher level of education (β 1.3, SE 0.48, p = 0.008). CONCLUSIONS Counseling by healthcare providers is associated with higher performance on a knowledge assessment about preeclampsia/eclampsia. Patient knowledge about preeclampsia/eclampsia is important for efforts to encourage informed healthcare decisions, promote early antenatal care, and improve self-recognition of warning signs-ultimately improving morbidity and reducing mortality.

Abstract
BACKGROUND Hypertensive disorders in pregnancy are the second most common cause of maternal mortality in the Democratic Republic of Congo (DRC), accounting for 23% of maternal deaths. This study aimed to assess facility readiness, and providers' knowledge to prevent, diagnose, and treat pre-eclampsia. METHODS A facility-based cross-sectional study was conducted in 30 primary health centres (PHCs) and 28 referral facilities (hospitals) randomly selected in Kinshasa, DRC. In each facility, all midwives and physicians involved in maternal care provision (n = 197) were included. Data on facility infrastructure and providers' knowledge about pre-eclampsia were collected using facility checklists and a knowledge questionnaire. Facility readiness score was defined as the sum of 13 health commodities needed to manage pre-eclampsia. A knowledge score was defined as the sum of 24 items about the diagnosis, management, and prevention of pre-eclampsia. The score ranges from 0 to 24, with higher values reflecting a better knowledge. The Mann-Witney U test was used to compare median readiness scores by facility type and ownership; and median knowledge scores between midwives in hospitals and in PHCs, and between physicians in hospitals and in PHCs. RESULTS Overall, health facilities had 7 of the 13 commodities, yielding a median readiness score of 53.8%(IQR: 46.2 to 69.2%). Although all provider groups had significant knowledge gaps about pre-eclampsia, providers in hospitals demonstrated slightly more knowledge than those in PHCs. Midwives in public facilities scored higher than those in private facilities (median(IQR): 8(5 to 12) vs 7(4 to 8), p = 0.03). Of the 197 providers, 91.4% correctly diagnosed severe pre-eclampsia. However, 43.9 and 82.2% would administer magnesium sulfate and anti-hypertensive drugs to manage severe pre-eclampsia, respectively. Merely 14.2 and 7.1% of providers were aware of prophylactic use of aspirin and calcium to prevent pre-eclampsia, respectively. CONCLUSION Our study showed poor availability of supplies to diagnose, prevent and treat pre-eclampsia in Kinshasa. While providers demonstrated good knowledge regarding the diagnosis of pre-eclampsia, they have poor knowledge regarding its prevention and management. The study highlights the need for strengthening knowledge of providers toward the prevention and management of pre-eclampsia, and enhancing the availability of supplies needed to address this disease.

Our objective was to compare clinical outcomes to those from a clinical trial after implementation of the program in a second hospital within our hospital system. STUDY DESIGN Comparison of women randomized to text-based BP monitoring in a clinical trial compared to an implementation cohort clinically enrolled in text-based BP monitoring. BP outcomes and postpartum visit were compared in bivariate and multivariable analyses. MAIN OUTCOME MEASURES BP ascertainment was defined as at least 1 BP texted during the 10 days of monitoring. American College of Obstetricians and Gynecologists (ACOG) recommendation was defined as BP sent on postpartum day 3-4 and again day 7-10. RESULTS The implementation cohort had 333 women compared to 103 in the trial cohort. The implementation cohort was older (p < 0.001), and more likely to be non-Black race (p < 0.001), married (<0.001), and have commercial insurance (<0.001). BP ascertainment (95.5% vs. 92.2%, adjusted OR 1.41, [95% CI 0.55, 3.58]) and proportion meeting ACOG recommendations (84.7% vs. 81.6%, adjusted OR 0.89 [95% CI 0.48, 1.64]) were similar between groups. There were no differences in BP ascertainment among Black and non-Black women in the trial or implementation cohort. CONCLUSIONS Text-based BP monitoring performed similarly in an implementation cohort compared to the trial participants. This program is scalable to manage postpartum hypertension and reduce racial disparities in postpartum care in women with hypertensive disorders of pregnancy.

Abstract
BACKGROUND To overcome the three delays in triage, transport and treatment that underlie adverse pregnancy outcomes, we aimed to reduce all-cause adverse outcomes with community-level interventions targeting women with pregnancy hypertension in three low-income countries. METHODS In this individual participant-level meta-analysis, we de-identified and pooled data from the Community-Level Interventions for Pre-eclampsia (CLIP) cluster randomised controlled trials in Mozambique, Pakistan, and India, which were run in 2014-17. Consenting pregnant women, aged 12-49 years, were recruited in their homes. Clusters, defined by local administrative units, were randomly assigned (1:1) to intervention or control groups. The control groups continued local standard of care. The intervention comprised community engagement and existing community health worker-led mobile health-supported early detection, initial treatment, and hospital referral of women with hypertension. For this meta-analysis, as for the original studies, the primary outcome was a composite of maternal or perinatal outcome (either maternal, fetal, or neonatal death, or severe morbidity for the mother or baby), assessed by unmasked trial surveillance personnel. For this analysis, we included all consenting participants who were followed up with completed pregnancies at trial end. We analysed the outcome data with multilevel modelling and present data with the summary statistic of adjusted odds ratios (ORs) with 95% CIs (fixed effects for maternal age, parity, maternal education, and random effects for country and cluster). This meta-analysis is registered with PROSPERO, CRD42018102564. FINDINGS Overall, 44 clusters (69 330 pregnant women) were randomly assigned to intervention (22 clusters [36 008 pregnancies]) or control (22 clusters [33 322 pregnancies]) groups. 32 290 (89·7%) pregnancies in the intervention group and 29 698 (89·1%) in the control group were followed up successfully. Median maternal age of included women was 26 years (IQR 22-30). In the intervention clusters, 6990 group and 16 691 home-based community engagement sessions and 138 347 community health worker-led visits to 20 819 (57·8%) of 36 008 women (of whom 11 095 [53·3%] had a visit every 4 weeks) occurred. Blood pressure and dipstick proteinuria were assessed per protocol. Few women were eligible for methyldopa for severe hypertension (181 [1%] of 20 819) or intramuscular magnesium sulfate for pre-eclampsia (198 [1%]), of whom most accepted treatment (162 [89·5%] of 181 for severe hypertension and 133 [67·2%] of 198 for pre-eclampsia). 1255 (6%) were referred to a comprehensive emergency obstetric care facility, of whom 864 (82%) accepted the referral. The primary outcome was similar in the intervention (7871 [24%] of 32 290 pregnancies) and control clusters (6516 [22%] of 29 698; adjusted OR 1·17, 95% CI 0·90-1·51; p=0·24). No intervention-related serious adverse events occurred, and few adverse effects occurred after in-community treatment with methyldopa (one [2%] of 51; India only) and none occurred after in-community treatment with magnesium sulfate or during transport to facility. INTERPRETATION The CLIP intervention did not reduce adverse pregnancy outcomes. Future community-level interventions should expand the community health worker workforce, assess general (rather than condition-specific) messaging, and include health system strengthening.

Abstract
Some complications of pregnancy that occur in the second trimester, such as preeclampsia, bleeding placenta previa, and preterm premature rupture of membranes, require delivery to avoid maternal morbidity and mortality. When these situations occur before fetal viability, pregnancy termination, either by induction of labor or dilation and evacuation, can be lifesaving. To optimize maternal health in these situations, Maternal Fetal Medicine providers should be trained to provide all needed medical services, including termination. Currently, only the minority of Maternal Fetal Medicine providers are skilled in dilation and evacuation. Training programs should focus on ways to facilitate training in second trimester dilation and evacuation to improve care access and quality when these medically necessary procedures are needed for women in whom a healthy pregnancy is no longer an option.

Abstract
INTRODUCTION Kasabach-Merritt Syndrome (KMS) is an extremely rare disease in adults, which lead to consumptive coagulopathy characterized by severe hypofibrinogenemia and thrombocytopenia. PATIENT CONCERNS:: a 25-year-old Chinese pregnant women complicated by preeclampsia and KMS presented with refractory postpartum hemorrhage and incision bleeding after cesarean section. DIAGNOSIS The diagnosis of KMS was made based on clinical manifestation of Kaposiform Hemangioendothelioma, severe hypofibrinogenemia and thrombocytopenia. INTERVENTIONS After a poor response to massive blood products transfusion for 1 week, corticosteroid treatment was initiated for 3 days. OUTCOMES The patient reached a normal platelet count and a mild anemia within 4 weeks. Two months later, all laboratory values had returned to normal, and the incision was healing well. CONCLUSION Pregnancy complicated by preeclampsia and surgery may have contributions for the development of Kasabach-Merritt syndrome. Corticosteroid is indicated in the episode of acute Kasabach-Merritt syndrome after the failure of massive blood transfusion.

Abstract
OBJECTIVES Pregnancy hypertension is the third leading cause of maternal mortality in Mozambique and contributes significantly to fetal and neonatal mortality. The objective of this trial was to assess whether task-sharing care might reduce adverse pregnancy outcomes related to delays in triage, transport, and treatment. STUDY DESIGN The Mozambique Community-Level Interventions for Pre-eclampsia (CLIP) cluster randomised controlled trial (NCT01911494) recruited pregnant women in 12 administrative posts (clusters) in Maputo and Gaza Provinces. The CLIP intervention (6 clusters) consisted of community engagement, community health worker-provided mobile health-guided clinical assessment, initial treatment, and referral to facility either urgently (<4hrs) or non-urgently (<24hrs), dependent on algorithm-defined risk. Treatment effect was estimated by multi-level logistic regression modelling, adjusted for prognostically-significant baseline variables. Predefined secondary analyses included safety and evaluation of the intensity of CLIP contacts. MAIN OUTCOME MEASURES 20% reduction in composite of maternal, fetal, and newborn mortality and major morbidity. RESULTS 15,013 women (15,123 pregnancies) were recruited in intervention (N = 7930; 2·0% loss to follow-up (LTFU)) and control (N = 7190; 2·8% LTFU) clusters. The primary outcome did not differ between intervention and control clusters (adjusted odds ratio (aOR) 1·31, 95% confidence interval (CI) [0·70, 2·48]; p = 0·40). Compared with intervention arm women without CLIP contacts, those with ≥8 contacts experienced fewer primary outcomes (aOR 0·79 (95% CI 0·63, 0·99); p = 0·041), primarily due to improved maternal outcomes (aOR 0·72 (95% CI 0·53, 0·97); p = 0·033). INTERPRETATION As generally implemented, the CLIP intervention did not improve pregnancy outcomes; community implementation of the WHO eight contact model may be beneficial.

Abstract
Introduction The World Health Organization (WHO) Safe Childbirth Checklist (SCC) is a 29-item checklist based on essential childbirth practices to help health-care workers to deliver consistently high quality maternal and perinatal care. The Checklist was intended to reduce maternal and perinatal mortality and address the primary cause of maternal death, intrapartum stillbirth, and early neonatal death. The objective of this review was to locate international literature reporting on the effectiveness of utilizing the WHO safe childbirth checklist on improving essential childbirth practices, early neonatal death, stillbirth, maternal mortality, and morbidity. Methods We searched MEDLINE, google scholar, Cochrane Central Register of Controlled Trials (CENTRAL), met-Register of Controlled Trials (m-RCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/stop/search/en) to retrieve all available comparative studieshttp://www.opengrey.eu/ published in English after 2008. Two reviewers did study selection, critical appraisal, and data extraction independently. We did a random or fixed-effect meta-analysis to pool studies together and effect estimates were expressed as an odds ratio. Quality of evidence for major outcomes was assessed using the Grading of Recommendations, Assessment, development, and evaluation(GRADE). Results We retained three cluster randomized trials and six pre-and-post intervention studies reporting on WHO SCC's. The WHO SCC utilization improved quality of preeclampsia management(moderate quality of evidence) (OR = 7.05 [95% CI 2.34–21.29]), maternal infection management(moderate quality of evidence) (OR = 7.29[95%CI 2.29–23.27]), Partograph utilization(moderate quality of evidence) (OR = 3.81 [95% 1.72–8.43]), postpartum counselling(low quality of evidence) (RR = 132.51[95% 49.27–356.36]) and still birth(moderate quality of evidence) (OR = 0.92[95% CI 0.87–0.96]). However, the utilization of the checklist had no impact on early neonatal death (very low quality of evidence) (OR = 1.07[95%CI [1.01–1.13]) and maternal death (low quality of evidence) (OR = 1.06[95% CI 0.77–1.45]). Conclusions Moderate quality of evidence indicates that WHO SCC utilization is effective in reducing stillbirth and Improving preeclampsia management, maternal infection management and partograph utilization Low quality of evidence indicates that WHO SCC is effective in enhancing postpartum danger sign counseling. Low and very low quality of evidence suggests that WHO SCC has no impact on maternal and early neonatal death, respectively.

Abstract
OBJECTIVES To undertake a systematic review of the safety and effectiveness of mind body approaches for women with hypertensive disorders in pregnancy (HDP). DESIGN A search was undertaken of databases from inception to 2019 for randomised and quasi randomised controlled trials. MAIN OUTCOME MEASURES The primary outcome was a reduction in systolic and / or diastolic blood pressure for women with hypertension and or preeclampsia in pregnancy. RESULTS 121 studies were identified and eight studies were included in this review. These included mind body interventions examining yoga, guided imagery, relaxation, music, and acupuncture for HDP. Two studies of relaxation found a reduction in systolic (MD -11.3, 95%CI -13.23 to -9.39) and diastolic blood pressure (MD -6.59, 95%CI -9.43 to -3.75) and reduced stress (MD -11.4, 95%CI -16.5 to -6.3). In one study of yoga, the risk of developing HDP was reduced (RR 0.28, 95% CI 0.09 to 0.91, 59 women) and a second study found a reduction in stress at the end of the intervention of yoga. One trial of guided imagery found a reduction in mean arterial blood pressure compared to the control (4.35, 95% -8.04 to -0.66, p=0.02). Overall there was no effect on the development of preeclampsia, use of anti-hypertensive medication and any neonatal outcomes from the interventions evaluated. Few trials reported on safety outcomes, one trial of acupuncture reported one case of placental abruption and three cases of acupuncture related side effects. CONCLUSION Few high quality trials have examined the effectiveness and safety of mind body interventions to manage HDP. Relaxation, yoga, guided imagery and music may have some potential benefit. Safety issues are completely unclear and thus the risk-benefit ratio of all interventions could not be determined. Further research is recommended.

Abstract
Preeclampsia is defined as new-onset hypertension after the 20th wk of gestation along with evidence of maternal organ failure. Rates of preeclampsia have steadily increased over the past 30 yr, affecting ∼4% of pregnancies in the United States and causing a high economic burden (22, 69). The pathogenesis is multifactorial, with acknowledged contributions by placental, vascular, renal, and immunological dysfunction. Treatment is limited, commonly using symptomatic management and/or early delivery of the fetus (6). Along with significant peripartum morbidity and mortality, current research continues to demonstrate that the consequences of preeclampsia extend far beyond preterm delivery. It has lasting effects for both mother and child, resulting in increased susceptibility to hypertension and chronic kidney disease (45, 54, 115, 116), yielding lifelong risk to both individuals. This review discusses recent guideline updates and recommendations along with current research on these long-term consequences of preeclampsia.

Abstract
OBJECTIVES Several studies have focused on the benefits of physical activity to prevent and treat preeclampsia, given that preeclampsia and cardiovascular disease share several risk factors. However, none of these studies have been conducted in Africa. Moreover, it has been demonstrated that exercise training has preventive effects on the development of preeclampsia in mouse models. Therefore, we evaluated the association between the practice of physical activity and the development of this pathology in a Tunisian cohort. STUDY DESIGN Sixty-one healthy pregnant Tunisian women and 45 women with preeclampsia were recruited and completed the Pregnancy Physical Activity Questionnaire to determine their level and type of physical activity during the entire pregnancy. MAIN OUTCOME MEASURE Continuous variables were compared using the Mann-Whitney U test, while categorical variables were compared using the Chi-square test. The correlation between preeclampsia features and energy expenditure were assessed using the Pearson's correlation test. RESULTS Energy expenditure analysis revealed that women with preeclampsia engaged in more sedentary activities than controls, while controls practiced more physical activities. Interestingly, we found a positive correlation between the total amount of energy spent and the duration of pregnancy in controls and women with preeclampsia. CONCLUSIONS Increasing physical activity is correlated with increasing pregnancy duration which is an index of maternal and fetal health. The practice of physical activities during pregnancy is associated with a healthier pregnancy, while sedentary activities is associated with the development of preeclampsia.

Abstract
Background Preeclampsia refers to the new onset of hypertension and proteinuria after 20 weeks of gestation in a previously normotensive woman. Pregnant women with preeclampsia are at an increased risk of adverse maternal, fetal and neonatal complications. The objective of the study is, therefore, to determine the maternal and perinatal outcome of preeclampsia without severity feature among women managed at a tertiary referral hospital in urban Ethiopia. Methods A hospital-based prospective observational study was conducted to evaluate the maternal and perinatal outcome of pregnant women who were on expectant management with the diagnosis of preeclampsia without severe feature at a referral hospital in urban Ethiopia from August 2018 to January 2019. Results There were a total of 5400 deliveries during the study period, among which 164 (3%) women were diagnosed with preeclampsia without severe features. Fifty-one (31.1%) patients with preeclampsia without severe features presented at a gestational age between 28 to 33 weeks plus six days, while 113 (68.9%) presented at a gestational age between 34 weeks to 36 weeks. Fifty-two (31.7%) women had maternal complication of which, 32 (19.5%) progressed to preeclampsia with severe feature Those patients with early onset of preeclampsia without severe feature were 5.22 and 25.9 times more likely to develop maternal and perinatal complication respectively compared to late-onset after 34 weeks with P-value of <0.0001, (95% CI 2.01–13.6) and <0.0001(95% CI 5.75–115.6) respectively. Conclusion In a setting where home-based self-care is poor expectant outpatient management of preeclampsia without severe features with a once per week visit is not adequate. It’s associated with an increased risk of maternal and perinatal morbidity and mortality. Our findings call for special consideration and close surveillance of those women with early-onset diseases.

Abstract
Increased plasma homocysteine is a risk factor for several pathological disorders. The present review focused on the role of homocysteine (Hcy) in different population groups, especially in risk conditions (pregnancy, infancy, old age), and on its relevance as a marker or etiological factor of the diseases in these age groups, focusing on the nutritional treatment of elevated Hcy levels. In pregnancy, Hcy levels were investigated in relation to the increased risk of adverse pregnancy outcomes such as small size for gestational age at birth, preeclampsia, recurrent abortions, low birth weight, or intrauterine growth restriction. In pediatric populations, Hcy levels are important not only for cardiovascular disease, obesity, and renal disease, but the most interesting evidence concerns study of elevated levels of Hcy in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). Finally, a focus on the principal pathologies of the elderly (cardiovascular and neurodegenerative disease, osteoporosis and physical function) is presented. The metabolism of Hcy is influenced by B vitamins, and Hcy-lowering vitamin treatments have been proposed. However, clinical trials have not reached a consensus about the effectiveness of vitamin supplementation on the reduction of Hcy levels and improvement of pathological condition, especially in elderly patients with overt pathologies, suggesting that other dietary and non-dietary factors are involved in high Hcy levels. The importance of novel experimental designs focusing on intra-individual variability as a complement to the typical case-control experimental designs and the study of interactions between different factors it should be emphasized.

Abstract
OBJECTIVE The Hypertension and Preeclampsia Intervention Trial At near Term-I (HYPITAT-I) randomized controlled trial showed that, in women with gestational hypertension or mild pre-eclampsia at term, induction of labor, compared with expectant management, was associated with improved maternal outcome without compromising neonatal outcome. The aim of the current study was to evaluate the impact of these findings on obstetric management and maternal and perinatal outcomes in The Netherlands. METHODS We retrieved data for the period 2000-2014 from the Dutch National Perinatal Registry, including 143 749 women with gestational hypertension or pre-eclampsia and a singleton fetus in cephalic presentation, delivered between 36 + 0 and 40 + 6 weeks of gestation (hypertensive disorder of pregnancy (HDP) group). Pregnant women without HDP were used as the reference group (n = 1 649 510). The HYPITAT-I trial was conducted between 2005 and 2008. To study the impact of HYPITAT-I, we compared rate of induction of labor, mode of delivery and maternal and perinatal outcomes in the periods before (2000-2005) and after (2008-2014) the trial. We also differentiated between hospitals that participated in HYPITAT-I and those that did not. RESULTS In the HDP group, the rate of induction of labor increased from 51.1% before the HYPITAT-I trial to 64.2% after it (relative risk (RR), 1.26; 95% CI, 1.24-1.27). Maternal mortality decreased from 0.022% before the trial to 0.004% after it (RR, 0.20; 95% CI, 0.06-0.70) and perinatal death decreased from 0.49% to 0.27% (RR, 0.54; 95% CI, 0.45-0.65), which was attributable mostly to a decrease in fetal death. Both the increase in induction rate and the reduction in hypertensive complications were more pronounced in hospitals that participated in the HYPITAT-I trial than in those that did not. Following HYPITAT-I, the rate of induction of labor also increased (by 4.6 percentage points) in the reference group; however, the relative increase in the HDP group (13.1 percentage points) was significantly greater (P < 0.001 for the interaction). The reduction in maternal and perinatal deaths did not differ significantly between the HDP and reference groups. There was a decreased incidence of placental abruption in both HDP and reference groups, which was significantly greater in the HDP than in the reference group (P < 0.001 for the interaction). There was also an increased incidence of emergency Cesarean section in both HDP and reference groups; however, this change was significantly greater in the reference than in the HDP group (P < 0.001 for the interaction). CONCLUSION Following the HYPITAT-I trial, there was a higher rate of induction of labor and improved obstetric outcome in term pregnancies complicated by HDP in The Netherlands.

Abstract
Antiphospholipid syndrome (APS) is a rare systemic autoimmune disease, the obstetric features of which include recurrent early miscarriage, fetal death at or beyond 10 weeks of gestation, and early delivery for severe preeclampsia or placental insufficiency. Controversies regarding the specificity of these obstetric clinical features, as well as the laboratory diagnostic criteria, are the subject of current debate and reanalysis. Clinical and laboratory features can be used to stratify women with APS in terms of risk of adverse second and third trimester pregnancy outcomes. Numerous "treatments" have been used in high-risk and refractory patients, but rigorously designed clinical trials are needed. APS is a rare disease that requires innovative investigative approaches to provide credible results.

Abstract
PURPOSE OF REVIEW To review the postpartum management of hypertensive disorders of pregnancy. RECENT FINDINGS Hypertensive disorders are associated with an increased risk of future cardiovascular disease; however, there is a poor understanding of the underlying mechanisms and few recommendations to guide care in the postpartum period. Recent studies have shown high rates of masked hypertension and home blood pressure monitoring in the first year postpartum may be a promising opportunity to monitor health given evidence of high maternal adherence to this approach. In longer term, women with a history of a hypertensive disorder of pregnancy have higher blood pressures, increased risk of metabolic syndrome, and perhaps excess diastolic dysfunction. Triaging risk and improving handoff from the obstetrician to the primary care provider or subspecialist should be a priority in this population. Hypertensive disorders of pregnancy remain an untapped opportunity to identify excess cardiovascular risk in affected women at a time when mitigating that risk during the reproductive years has the potential to improve future pregnancy health as well as improve women's long-term cardiometabolic health.

Abstract
Preeclampsia is a common cause of acute kidney injury (AKI) in low- and middle-income countries, but AKI incidence in preeclampsia, its risk factors, and renal outcomes are unknown. A prospective observational multicenter study of women admitted with preeclampsia in South Africa was conducted. Creatinine concentrations were extracted from national laboratory databases for women with maximum creatinine of ≥90 μmol/L (≥1.02 mg/dL). Renal injury and recovery were defined by Kidney Disease Improving Global Outcomes creatinine criteria. Predefined risk factors, maternal outcomes, and neonatal outcomes were compared between AKI stages. Of 1547 women admitted with preeclampsia 237 (15.3%) met AKI criteria: 6.9% (n=107) stage 1, 4.3% (n=67) stage 2, and 4.1% (n=63) stage 3. There was a higher risk of maternal death (n=7; relative risk, 4.3; 95% CI, 1.6-11.4) and stillbirth (n=80; relative risk, 2.2; 95% CI, 1.8-2.8) in women with AKI compared with those without. Perinatal mortality was also increased (89 of 240; 37.1%). Hypertension in a previous pregnancy was the strongest predictor of AKI stage 2 or 3 (odds ratio, 2.24; 95% CI, 1.21-4.17). Renal recovery rate reduced with increasing AKI stage. A third of surviving women (76 of 230 [33.0%]) had not recovered baseline renal function by discharge. Approximately half (39 of 76; 51.3%) of these women had no further creatinine testing post-discharge. In summary, AKI was common in women with preeclampsia and had high rates of associated maternal and perinatal mortality. Only two-thirds of women had confirmed renal recovery. History of a previous hypertensive pregnancy was an important risk factor.

Abstract
Preeclampsia is a serious complication of pregnancy affecting 3-8% of all pregnancies. It increases the morbidity and mortality of both the fetus and the pregnant woman, especially in developing countries. It deleteriously affects several vital organs, including the kidney, heart, liver, brain, and lung. Although, the pathogenesis of preeclampsia has not yet been fully understood, growing evidence suggests that aberrations in the angiogenic factors levels/activity and coagulopathy are responsible for the clinical manifestations of the disease. The common nominator of tissue damage of all these target organs is endothelial injury, which impedes their normal function. At the renal level, glomerular endothelial injury leads to the development of maternal hypertension and proteinuria. Similarly, this disease can cause hepatic and neurologic dysfunction due to vascular damage. The current review summarizes the recent development in the pathogenesis of this disease state with special focus on novel diagnostic biomarkers and their relevance to potential therapeutic options for preeclampsia. Specifically, we will highlight the renal manifestations of the diseases with emphasis on the involvement of angiogenic factors in vascular injury and how restoration of the angiogenic balance affects the renal and cardiovascular outcome of preeclamptic women.

Abstract
BACKGROUND Preeclampsia (PE) is a major cause of short and long-term morbidity for affected infants, including consequences of fetal growth restriction and iatrogenic prematurity. In Brazil, this is a special problem as PE accounts for 18% of preterm births (PTB). In the PREPARE (Prematurity REduction by Pre-eclampsia cARE) study, we will test a novel system of integrated care based on risk stratification and knowledge transfer, to safely reduce PTB. METHODS This is a stepped wedge cluster randomised trial that will include women with suspected or confirmed PE between 20 + 0 and 36 + 6 gestational weeks. All pregnant women presenting with these findings at seven tertiary centres in geographically dispersed sites, throughout Brazil, will be considered eligible and evaluated in terms of risk stratification at admission. At randomly allocated time points, sites will transition to risk stratification performed according to sFlt-1/PlGF (Roche Diagnostics) measurement and fullPIERS score with both results will be revealed to care providers. The healthcare providers of women stratified as low risk for adverse outcomes (sFlt-1/PlGF ≤38 AND fullPIERS< 10% risk) will receive the recommendation to defer delivery. sFlt-1/PlGF will be repeated once and fullPIERS score twice a week. Rates of prematurity due to preeclampsia before and after the intervention will be compared. Additionally, providers will receive an active program of knowledge transfer about WHO recommendations for preeclampsia, including recommendations regarding antenatal corticosteroids for foetal benefits, antihypertensive therapy and magnesium sulphate for seizure prophylaxis. This study will have 90% power to detect a reduction in PTB associated with PE from a population estimate of 1.5 to 1.0%, representing a 33% risk reduction, and 80% power to detect a reduction from 2.0 to 1.5% (25% risk reduction). The necessary number of patients recruited to achieve these results is 750. Adverse events, serious adverse events, both anticipated and unanticipated will be recorded. DISCUSSION The PREPARE intervention expects to reduce PTB and improve care of women with PE without significant adverse side effects. If successful, this novel pathway of care is designed for rapid translation to healthcare throughout Brazil and may be transferrable to other low and middle income countries.

Abstract
BACKGROUND In women with late preterm pre-eclampsia, the optimal time to initiate delivery is unclear because limitation of maternal disease progression needs to be balanced against infant complications. The aim of this trial was to determine whether planned earlier initiation of delivery reduces maternal adverse outcomes without substantial worsening of neonatal or infant outcomes, compared with expectant management (usual care) in women with late preterm pre-eclampsia. METHODS In this parallel-group, non-masked, multicentre, randomised controlled trial done in 46 maternity units across England and Wales, we compared planned delivery versus expectant management (usual care) with individual randomisation in women with late preterm pre-eclampsia from 34 to less than 37 weeks' gestation and a singleton or dichorionic diamniotic twin pregnancy. The co-primary maternal outcome was a composite of maternal morbidity or recorded systolic blood pressure of at least 160 mm Hg with a superiority hypothesis. The co-primary perinatal outcome was a composite of perinatal deaths or neonatal unit admission up to infant hospital discharge with a non-inferiority hypothesis (non-inferiority margin of 10% difference in incidence). Analyses were by intention to treat, together with a per-protocol analysis for the perinatal outcome. The trial was prospectively registered with the ISRCTN registry, ISRCTN01879376. The trial is closed to recruitment but follow-up is ongoing. FINDINGS Between Sept 29, 2014, and Dec 10, 2018, 901 women were recruited. 450 women (448 women and 471 infants analysed) were allocated to planned delivery and 451 women (451 women and 475 infants analysed) to expectant management. The incidence of the co-primary maternal outcome was significantly lower in the planned delivery group (289 [65%] women) compared with the expectant management group (338 [75%] women; adjusted relative risk 0·86, 95% CI 0·79-0·94; p=0·0005). The incidence of the co-primary perinatal outcome by intention to treat was significantly higher in the planned delivery group (196 [42%] infants) compared with the expectant management group (159 [34%] infants; 1·26, 1·08-1·47; p=0·0034). The results from the per-protocol analysis were similar. There were nine serious adverse events in the planned delivery group and 12 in the expectant management group. INTERPRETATION There is strong evidence to suggest that planned delivery reduces maternal morbidity and severe hypertension compared with expectant management, with more neonatal unit admissions related to prematurity but no indicators of greater neonatal morbidity. This trade-off should be discussed with women with late preterm pre-eclampsia to allow shared decision making on timing of delivery.

Abstract
INTRODUCTION Pre-eclampsia is a hypertensive disorder in pregnancy. Maternal sequelae that may occur include impaired liver function, disseminated intravascular coagulation, seizures (eclampsia), stroke, and death. Thus, providers should know how to recognize (diagnose) and treat pre-eclampsia and eclampsia. METHODS A simulator with noninvasive blood pressure monitoring was used. Transducers for fetal heart rate and contraction monitoring were placed on the simulator, which represented the patient. After obtaining a history and performing a physical examination, resident physician (postgraduate years 1-4) and nurse learners had to diagnose pre-eclampsia and treat this condition. They also had to treat severe-range blood pressures and manage eclampsia. Learner performance was assessed with a checklist. Debriefing followed the simulation. RESULTS Thirty resident learners participated in the study. Nurses did not participate. All resident learners indicated familiarity with the diagnosis and management of pre-eclampsia and emergent hypertension and managed these conditions correctly. All resident learners reported not being confident in managing eclampsia. None of the learners were able to stop the eclamptic seizure. All resident learners were more confident in managing eclampsia after the scenario compared with before (mean confidence level 3.6 ± 0.5 vs. 1.1 ± 0.4, p < .001). DISCUSSION Resident learners were familiar with the management of pre-eclampsia and emergent hypertension but not with eclampsia. We recommend that eclampsia simulations occur in a laboratory and in situ on the labor and delivery floor with interprofessional team members including obstetricians, nurses, anesthesiologists, emergency and family medicine physicians, nurse practitioners, and physician assistants.

Competence of healthcare professionals in diagnosing and managing obstetric complications and conducting neonatal care: a clinical vignette-based assessment in district and subdistrict hospitals in northern Bangladesh. BMJ Open 2019; 9:e028670.

Abstract
BACKGROUND This study assesses the competency of maternal and neonatal health (MNH) professionals at district-level and subdistrict-level health facilities in northern Bangladesh in managing maternal and newborn complications using clinical vignettes. The study also examines whether the professional's characteristics and provision of MNH services in health facilities influence their competencies. METHODS 134 MNH professionals in 15 government hospitals were interviewed during August and September 2016 using structured questionnaire with clinical vignettes on obstetric complications (antepartum haemorrhage and pre-eclampsia) and neonatal care (low birthweight and immediate newborn care). Summative scores were calculated for each vignette and median scores were compared across different individual-level and health facility-level attributes to examine their association with competency score. Kruskal-Wallis test was performed to identify the significance of association considering a p value<0.05 as statistically significant. RESULTS The competency of MNH professionals was low. About 10% and 24% of the health professionals received 'high' scores (>75% of total) in maternal and neonatal vignettes, respectively. Medical doctors had higher competency than nurses and midwives (score=11 vs 8 out of 19, respectively; p=0.0002) for maternal vignettes, but similar competency for neonatal vignettes (score=30.3 vs 30.9 out of 50, respectively). Professionals working in health facilities with higher use of normal deliveries had better competency than their counterparts. Professionals had higher competency in newborn vignettes (significant) and maternal vignettes (statistically not significant) if they worked in health facilities that provided more specialised newborn care services and emergency obstetric care, respectively, in the last 6 months. CONCLUSIONS Despite the overall low competency of MNH professionals, exposure to a higher number of obstetric cases at the workplace was associated with their competency. Arrangement of periodic skill-based and drill-based in-service training for MNH professionals in high-use neighbouring health facilities could be a feasible intervention to improve their knowledge and skill in obstetric and neonatal care.

Abstract
PURPOSE OF REVIEW This review provides a comprehensive insight into the angiogenic profile of hypertensive and normotensive pregnancies compromised by HIV infection. Furthermore, we evaluate the economic implementation of the sFlt-1/PlGF ratio and review the reports on therapeutic apheresis in limiting sFlt-1 production. RECENT FINDINGS In preeclampsia, an increased expression of sFlt-1 triggers angiogenic imbalance. Women of African ancestry have high levels of angiogenic factors than other racial groups. The sFlt-1/PlGF ratio shows promise in the early assessment of preeclampsia, while sFlt-1 apheresis restores angiogenic imbalance. Studies suggest antiretroviral therapy does not impact the angiogenic shift in preeclampsia development. The angiogenic profile in pregnant women of different races influences preeclampsia development. Despite the opposing immune response in HIV infection and preeclampsia, the HIV tat protein strongly mimics vascular endothelial growth factor (VEGF); hence, it is plausible to assume that HIV infection may ameliorate the angiogenic imbalance in preeclampsia.

Abstract
Preeclampsia is a serious, pregnancy-specific, multi-organ disease process of compound aetiology. It affects 3–6% of expecting mothers worldwide and it persists as a leading cause of maternal and foetal morbidity and mortality. In fact, hallmark features of preeclampsia (PE) result from vessel involvement and demonstrate maternal endothelium as a target tissue. Growing evidence suggests that chronic placental hypoperfusion triggers the production and release of certain agents that are responsible for endothelial activation and injury. In this review, we will present the latest findings on the role of nitric oxide, asymmetric dimethylarginine (ADMA), and homocysteine in the etiopathogenesis of preeclampsia and their possible clinical implications.

Abstract
BACKGROUND Preeclampsia remains a significant danger to both mother and child and current prevention and treatment management strategies are limited. The objective of this systematic review was to investigate the current literature on evidence for the use of the regenerative capacity of mesenchymal stem cell (MSC) therapy, the anticoagulant activity of antithrombin (AT), or the free radical scavenging activity of alpha-1-microglobulin (A1M) as potential novel treatments for severe preeclampsia and Hemolysis, Elevated Liver enzymes, Low Platelet count (HELLP). METHOD We conducted a systematic review of potential biological therapies for preeclampsia. We screened MEDLINE and Embase from inception through May 2017 for studies using AT, A1M or MSCs as potential treatments for preeclampsia and/or HELLP. A meta-analysis was performed to pool data from randomized control trials (RCTs) with homogenous outcomes using the inverse variance method. The Newcastle-Ottawa Scale, the Cochrane risk of bias tool for RCTs, and SYRCLE's risk of bias tool for animal studies were used to investigate potential bias of studies. RESULTS The literature search retrieved a total of 1015 articles, however, only 17 studies met the selection criteria: AT (n = 9, 8 human and 1 animal); A1M (n = 4, 3 animal and 1 ex-vivo); and, MSCs (n = 4, 3 animal and 1 ex-vivo). A meta-analysis of AT therapy versus placebo and a meta-analysis for AT therapy with heparin versus heparin alone did not show significant differences between study groups. Animal and ex-vivo studies demonstrated significant benefits in relevant outcomes for A1M and MSCs versus control treatments. Most RCT studies were rated as having a low risk of bias across categories with some studies showing an unclear risk of bias in some categories. The two cohort studies both received a total of four out of nine stars (a rating of "poor" quality). Most animal studies had an unclear risk of bias across most categories, with some studies having a low risk of bias in some categories. CONCLUSIONS The findings of this review are strengthened by rigorous systematic search and review of the literature. Results of our meta-analyses do not currently warrant further exploration of AT as a treatment of preeclampsia in human trials. Results of animal and ex-vivo studies of A1M and MSCs were encouraging and supportive of initiating human investigations.

Abstract
Regulatory T cells, a subpopulation of suppressive T cells, are potent mediators of self-tolerance and essential for the suppression of triggered immune responses. The immune modulating capacity of these cells play a major role in both transplantation, autoimmune disease, allergy, cancer and pregnancy. During pregnancy, low numbers of regulatory T cells are associated with pregnancy failure and pregnancy complications such as pre-eclampsia. On the other hand, in cancer, low numbers of immunosuppressive T cells are correlated with better prognosis. Hence, maternal immune tolerance toward the fetus during pregnancy and the escape from host immunosurveillance by cancer seem to be based on similar immunological mechanisms being highly dependent on the balance between immune activation and suppression. As regulatory T cells hold a crucial role in several biological processes, they may also be promising subjects for therapeutic use. Especially in the field of cancer, cell therapy and checkpoint inhibitors have demonstrated that immune-based therapies have a very promising potential in treatment of human malignancies. However, these therapies are often accompanied by adverse autoimmune side effects. Therefore, expanding the knowledge to recognize the complexities of immune regulation pathways shared across different immunological scenarios is extremely important in order to improve and develop new strategies for immune-based therapy. The intent of this review is to highlight the functional characteristics of regulatory T cells in the context of mechanisms of immune regulation in pregnancy and cancer, and how manipulation of these mechanisms potentially may improve therapeutic options.

Abstract
In preeclampsia, vasospasm, oxidative stress, endothelial dysfunction, and immune dysregulation are key mediators of maternal disease. A new time-of-disease treatment is needed with the potential to treat these areas of pathophysiology. A review of the literature has indicated that metabolites of the kynurenine pathway have the potential to; (i) induce vasorelaxation of resistance arteries and reduce blood pressure; (ii) exert antioxidant effects and reduce the effects of poly-ADP ribose polymerase activation (iii) prevent endothelial dysfunction and promote endothelial nitric oxide production; (iv) cause T cell differentiation into tolerogenic regulatory T cells and induce apoptosis of pro-inflammatory Th1 cells. This has led to the hypothesis that increasing Kynurenine pathway activity may offer a new treatment strategy for preeclampsia.

Policy review on the management of pre-eclampsia and eclampsia by community health workers in Mozambique. HUMAN RESOURCES FOR HEALTH 2019; 17:15. [PMID: 30819211 PMCID: PMC6396495 DOI: 10.1186/s12960-019-0353-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2017] [Accepted: 02/15/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Pre-eclampsia is one of the leading causes of maternal death in Mozambique. Limited access to health care facilities and a lack of skilled health professionals contribute to the high maternal morbidity and mortality rates in Mozambique and indicate a need for community-level interventions. The aim of this review was to identify and characterise health policies related to the role of CHWs in the management of pre-eclampsia and eclampsia in Mozambique. METHODS The policy review was based on three methods: a desk review of relevant documents from the Mozambique Ministry of Health (n = 7), contact with 28 key informants in the field of health policy in Mozambique (n = 5) and literature review (n = 699). Policy documents obtained included peer-reviewed articles, government and institutional policies, reports and action plans. Seven hundred and eleven full-text documents were assessed for eligibility and included based on pre-defined criteria. Qualitative analysis was done to identify main themes using content analysis. RESULTS A total of 56 papers informed the timeline of key events. Three main themes were identified from the qualitative review: establishment of the community health worker programme and early challenges, revitalization of the CHW programme and the integration of maternal health in the community health tasks. In 1978, following the Alma Alta Declaration, the Mozambique government brought in legislation establishing primary health care and the CHW programme. Between the late 1980s and early 1990s, this programme was scaled down due to several factors including a prolonged civil war; however, the decision to revitalise the programme was made in 1995. In 2010, a revitalised programme was re-launched and expanded to include the management of common childhood illnesses, detection of warning signs of pregnancy complications, referrals for maternal health and basic health promotion. To date, their role has not included management of emergency conditions of pregnancy including pre-eclampsia and eclampsia. CONCLUSION The role of CHWs has evolved over the last 40 years to include care of childhood diseases and basic maternal health counselling. Studies to assess the impact of CHWs in providing services to reduce maternal morbidity and mortality are recommended.

Abstract
Headache is the fourth most common reason for emergency department encounters, accounting for 3% of all visits in the United States. Though troublesome, 90% are relatively benign primary headaches --migraine, tension, and cluster headaches. The other 10% are secondary headaches, caused by separate underlying processes, with vascular, infectious, or traumatic etiologies, and they are potentially life-threatening. This issue details the important pathophysiologic features of the most common types of life-threatening headaches, the key historical and physical examination information emergency clinicians must obtain, the red flags that cannot be missed, and the current evidence for best-practice testing, imaging, treatment, and disposition.

Abstract
OBJECTIVES To evaluate the feasibility and effectiveness of a postpartum lifestyle intervention after pregnancies complicated by preeclampsia, fetal growth restriction (FGR) and/or gestational diabetes mellitus (GDM) to improve maternal risk factors for future cardiometabolic disease. METHODS Women following a complicated pregnancy were included six months postpartum in this specific pre-post controlled designed study. It has been conducted in one tertiary and three secondary care hospitals (intervention group) and one secondary care hospital (control group). The program consisted of a computer-tailored health education program combined with three individual counselling sessions during seven months. Primary outcome measures were the proportion of eligible women and weight change during the intervention. RESULTS Two hundred and six women were willing to participate. The proportion of eligible women who complied with the intervention was 23%. Major barrier was lack of time. Adjusted weight change attributed to lifestyle intervention was -1.9 kg (95%-CI -4.3 to -0.3). Further changes were BMI (-0.9 kg/m2 (95%-CI -1.4 to -0.3)), waist-to-hip ratio (-0.04 cm/cm (95%-CI -0.06 to -0.03)), blood pressure medication use (19% (95%-CI 9% to 28%)), HOMA2-score (59 %S (95%-CI 18 to 99)) and total fat intake (-2.9 gr (95%-CI -4.6 to -1.2)). CONCLUSIONS The results support feasibility and effectiveness of a lifestyle intervention after complicated pregnancies to improve maternal cardiometabolic risk factors. Further randomized controlled studies are needed with longer follow-up to evaluate durability. In the meantime, we suggest health care professionals to offer lifestyle interventions to women after complicated pregnancies.

Abstract
OBJECTIVE To determine the effectiveness and economic impact of two methods for induction of labour in hypertensive women, in low-resource settings. DESIGN Cost-consequence analysis of a previously reported multicentre, parallel, open-label randomised trial. SETTING & POPULATION A total of 602 women with a live fetus, aged ≥18 years requiring delivery for pre-eclampsia or hypertension, in two public hospitals in Nagpur, India. METHODS We performed a formal economic evaluation alongside the INFORM clinical trial. Women were randomised to receive transcervical Foley catheterisation or oral misoprostol 25 mcg. Healthcare expenditure was calculated using a provider-side microcosting approach. MAIN OUTCOME MEASURES Rates of vaginal this delivery within 24 hours of induction, healthcare expenditure per completed treatment episode. RESULTS Induction with oral misoprostol resulted in a (mean difference) $20.6USD reduction in healthcare expenditure [95% CI (-) $123.59 (-) $72.49], and improved achievement of vaginal delivery within 24 hours of induction, mean difference 10% [95% CI (-2 to 17.9%), P = 0.016]. Oxytocin administration time was reduced by 135.3 minutes [95% CI (84.4-186.2 minutes), P < 0.01] and caesarean sections by 9.1% [95% CI (1.1-17%), P = 0.025] for those receiving oral misoprostol. Following probabilistic sensitivity analysis, oral misoprostol was cost-saving in 63% of 5,000 bootstrap replications and achieved superior rates of vaginal delivery, delivery within 24 hours of induction and vaginal delivery within 24 hours of induction in 98.7%, 90.7%, and 99.4% of bootstrap simulations. Based on univariate threshold analysis, the unit price of oral misoprostol 25 mcg could feasibly increase 31-fold from $0.24 to $7.50 per 25 mcg tablet and remain cost-saving. CONCLUSION Compared to Foley catheterisation for the induction of high-risk hypertensive women, oral misoprostol improves rates of vaginal delivery within 24 hours of induction and may also reduce costs. Additional research performed in other low-resource settings is required to determine their relative cost-effectiveness. TWEETABLE ABSTRACT Oral misoprostol less costly and more effective than Foley catheter for labour induction in hypertension.

Abstract
Preeclampsia is the cause of significant maternal and fetal mortality and morbidity. It is characterized by new-onset hypertension and proteinuria after 20 weeks of gestation. Preeclamptic women and children born from preeclamptic pregnancies are at greater risk to develop severe cardiovascular complications and metabolic syndromes later in life. The incidence of preeclampsia is estimated to be seven times higher in developing countries as compared to the developed countries. This review summarizes the pathophysiology of preeclampsia, emerging new hypothesis of its origin, risk factors that make women susceptible to developing preeclampsia and the potential of various biomarkers being studied to predict preeclampsia. The health care of developing countries is continuously challenged by substantial burden of maternal and fetal mortality. India despite being a fast developing country, is still far behind in achieving the required maternal mortality rates as per Millennium Development Goals set by the World Health Organization. Further, this review discusses the prevalence of preeclampsia in India, health facilities to manage preeclampsia, current guidelines and protocols followed and government policies to combat this complication in Indian condition.

Abstract
BACKGROUND Severe pre-eclampsia can cause significant mortality and morbidity for both mother and child, particularly when it occurs remote from term, between 24 and 34 weeks' gestation. The only known cure for this disease is delivery. Some obstetricians advocate early delivery to ensure that the development of serious maternal complications, such as eclampsia (fits) and kidney failure are prevented. Others prefer a more expectant approach, delaying delivery in an attempt to reduce the mortality and morbidity for the child that is associated with being born too early. OBJECTIVES To evaluate the comparative benefits and risks of a policy of early delivery by induction of labour or by caesarean section, after sufficient time has elapsed to administer corticosteroids, and allow them to take effect; with a policy of delaying delivery (expectant care) for women with severe pre-eclampsia between 24 and 34 weeks' gestation. SEARCH METHODS For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) on 27 November 2017, and reference lists of retrieved studies. SELECTION CRITERIA Randomised trials comparing the two intervention strategies for women with early onset, severe pre-eclampsia. Trials reported in an abstract were eligible for inclusion, as were cluster-trial designs. We excluded quasi-randomised trials. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. We assessed the quality of the evidence for specified outcomes using the GRADE approach. MAIN RESULTS We included six trials, with a total of 748 women in this review. All trials included women in whom there was no overriding indication for immediate delivery in the fetal or maternal interest. Half of the trials were at low risk of bias for methods of randomisation and allocation concealment; and four trials were at low risk for selective reporting. For most other domains, risk of bias was unclear. There were insufficient data for reliable conclusions about the comparative effects on most outcomes for the mother. Two studies reported on maternal deaths; neither study reported any deaths (two studies; 320 women; low-quality evidence). It was uncertain whether interventionist care reduced eclampsia (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.06 to 15.58; two studies; 359 women) or pulmonary oedema (RR 0.45, 95% CI 0.07 to 3.00; two studies; 415 women), because the quality of the evidence for these outcomes was very low. Evidence from two studies suggested little or no clear difference between the interventionist and expectant care groups for HELLP (haemolysis, elevated liver enzymes, and low platelets) syndrome (RR 1.09, 95% CI 0.62 to 1.91; two studies; 359 women; low-quality evidence). No study reported on stroke. With the addition of data from two studies for this update, there was now evidence to suggest that interventionist care probably made little or no difference to the incidence of caesarean section (average RR 1.01, 95% CI 0.91 to 1.12; six studies; 745 women; Heterogeneity: Tau² = 0.01; I² = 63%).For the baby, there was insufficient evidence to draw reliable conclusions about the effects on perinatal deaths (RR 1.11, 95% CI 0.62 to 1.99; three studies; 343 women; low-quality evidence). Babies whose mothers had been allocated to the interventionist group had more intraventricular haemorrhage (RR 1.94, 95% CI 1.15 to 3.29; two studies; 537 women; moderate-quality evidence), more respiratory distress caused by hyaline membrane disease (RR 2.30, 95% CI 1.39 to 3.81; two studies; 133 women), required more ventilation (RR 1.50, 95% CI 1.11 to 2.02; two studies; 300 women), and were more likely to have a lower gestation at birth (mean difference (MD) -9.91 days, 95% CI -16.37 to -3.45 days; four studies; 425 women; Heterogeneity: Tau² = 31.74; I² = 76%). However, babies whose mothers had been allocated to the interventionist group were no more likely to be admitted to neonatal intensive care (average RR 1.19, 95% CI 0.89 to 1.60; three studies; 400 infants; Heterogeneity: Tau² = 0.05; I² = 84%). Babies born to mothers in the interventionist groups were more likely to have a longer stay in the neonatal intensive care unit (MD 7.38 days, 95% CI -0.45 to 15.20 days; three studies; 400 women; Heterogeneity: Tau² = 40.93, I² = 85%) and were less likely to be small-for-gestational age (RR 0.38, 95% CI 0.24 to 0.61; three studies; 400 women). There were no clear differences between the two strategies for any other outcomes. AUTHORS' CONCLUSIONS This review suggested that an expectant approach to the management of women with severe early onset pre-eclampsia may be associated with decreased morbidity for the baby. However, this evidence was based on data from only six trials. Further large, high-quality trials are needed to confirm or refute these findings, and establish if this approach is safe for the mother.

Abstract
Preeclampsia continues to afflict 5% to 8% of all pregnancies throughout the world and is associated with significant morbidity and mortality to the mother and the fetus. Although the pathogenesis of the disorder has not yet been fully elucidated, current evidence suggests that imbalance in angiogenic factors is responsible for the clinical manifestations of the disorder, and may explain why certain populations are risk. In this review, we begin by demonstrating the roles that angiogenic factors play in pathogenesis of preeclampsia and its complications in the mother and the fetus. We then continue to report on the use of angiogenic markers as biomarkers to predict and risk-stratify disease. Strategies to treat preeclampsia by correcting the angiogenic balance, either by promoting proangiogenic factors or by removing antiangiogenic factors in both animal and human studies, are discussed. We end the review by summarizing status of the current preventive strategies and the long-term cardiovascular outcomes of women afflicted with preeclampsia.

Abstract
OBJECTIVE Soluble Fms-like tyrosine kinase-1 (sFlt-1) is thought to be causative in the pathogenesis of preeclampsia (PE) and specific removal of sFlt-1 via dextran sulfate cellulose (DSC)-apheresis was suggested as cure to allow prolongation of pregnancy in preterm PE. However, in addition a deranged lipoprotein metabolism may impact endothelial and placental function in PE. Lipoprotein-apheresis by heparin-mediated extracorporeal LDL-precipitation (H.E.L.P.) was previously applied and has been shown to alleviate symptoms in PE. This clinical trial reevaluates the clinical efficacy of H.E.L.P.-apheresis in PE considering sFlt-1. STUDY DESIGN Open pilot study assessing the prolongation by H.E.L.P.-apheresis in 6 women (30-41 years) with very preterm PE (24+4 to 27+0 gestational weeks (GW)) (NCT01967355) compared to a historic control-group matched for GW at admission (<28 GW; n = 6). Clinical outcome of mothers and babies, and pre- and post H.E.L.P.-apheresis levels of sFlt-1 and PlGF were monitored. MAIN OUTCOME MEASURES In apheresis patients (2-6 treatments), average time from admission to birth was 15.0 days (6.3 days in controls; p = 0.027). Lung maturation was induced in all treated cases, and all children were released in healthy condition. Apheresis reduced triglycerides and LDL-cholesterol by more than 40%. Although H.E.L.P.-apheresis induced a transient peak baseline levels did not change and rather stabilized sFlt-1 levels at pre-apheresis levels throughout treatments, with sFlt-1/PLGF ratio remaining unaffected. CONCLUSIONS H.E.L.P.-apheresis proved again to be safe and prolongs pregnancies in PE. However, without changing sFlt-1 levels below baseline lowering lipids or other yet undefined factors appear to be of more relevance than reducing sFlt-1.

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.
