Abstract
OBJECTIVE To estimate the association between mean arterial pressure during pregnancy and neonatal outcomes in participants with chronic hypertension using data from the CHAP (Chronic Hypertension and Pregnancy) trial. METHODS A secondary analysis of the CHAP trial, an open-label, multicenter randomized trial of antihypertensive treatment in pregnancy, was conducted. The CHAP trial enrolled participants with mild chronic hypertension (blood pressure [BP] 140-159/90-104 mm Hg) and singleton pregnancies less than 23 weeks of gestation, randomizing them to active treatment (maintained on antihypertensive therapy with a goal BP below 140/90 mm Hg) or standard treatment (control; antihypertensives withheld unless BP reached 160 mm Hg systolic BP or higher or 105 mm Hg diastolic BP or higher). We used logistic regression to measure the strength of association between mean arterial pressure (average and highest across study visits) and to select neonatal outcomes. Unadjusted and adjusted odds ratios (per 1-unit increase in millimeters of mercury) of the primary neonatal composite outcome (bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, or intraventricular hemorrhage grade 3 or 4) and individual secondary outcomes (neonatal intensive care unit admission [NICU], low birth weight [LBW] below 2,500 g, and small for gestational age [SGA]) were calculated. RESULTS A total of 2,284 participants were included: 1,155 active and 1,129 control. Adjusted models controlling for randomization group demonstrated that increasing average mean arterial pressure per millimeter of mercury was associated with an increase in each neonatal outcome examined except NEC, specifically neonatal composite (adjusted odds ratio [aOR] 1.12, 95% CI, 1.09-1.16), NICU admission (aOR 1.07, 95% CI, 1.06-1.08), LBW (aOR 1.12, 95% CI, 1.11-1.14), SGA below the fifth percentile (aOR 1.03, 95% CI, 1.01-1.06), and SGA below the 10th percentile (aOR 1.02, 95% CI, 1.01-1.04). Models using the highest mean arterial pressure as opposed to average mean arterial pressure also demonstrated consistent associations. CONCLUSION Increasing mean arterial pressure was positively associated with most adverse neonatal outcomes except NEC. Given that the relationship between mean arterial pressure and adverse pregnancy outcomes may not be consistent at all mean arterial pressure levels, future work should attempt to further elucidate whether there is an absolute threshold or relative change in mean arterial pressure at which fetal benefits are optimized along with maternal benefits.

Abstract
Hypertensive disorders of pregnancy (HDP) can result in significant maternal morbidity and even mortality. Available data suggest that many antihypertensives can be safely used in pregnant patients, albeit with close supervision of parameters like fetal growth and amniotic fluid volume. This article summarizes current guidelines on the diagnosis and treatment of hypertension in pregnancy and provides an in-depth guide to the available safety and efficacy data for antihypertensives during pregnancy and postpartum.

Abstract
BACKGROUND α/β- and β-blockers are essential in pregnant women's perinatal congenital heart disease management. Nevertheless, data on the effects of α/β- and β-blockers on pregnant women and fetuses are limited. We examined the risks of neonatal hypoglycemia and small for gestational age (SGA) associated with maternal exposure to α/β- and β-blockers.Methods and Results: All consecutive pregnant women with heart disease admitted to our hospital between January 2014 and October 2020 were included. Of 306 pregnancies (267 women), 32 were in the α/β-blocker group, 11 were in the β-blocker group, and 263 were in the control group. All 32 pregnancies in the α/β-blocker group were treated with carvedilol. In the β-blocker group, 4 women were treated with bisoprolol, 3 were treated with propranolol, 2 were treated with atenolol, 1 was treated with metoprolol, and 1 was treated nadolol. The incidence of neonatal hypoglycemia was higher in pregnant women taking carvedilol than in the control group (P=0.025). SGA was observed significantly more frequently in pregnant women taking β-blockers than in the carvedilol and control groups (P<0.001). CONCLUSIONS Carvedilol administration during pregnancy was associated with neonatal hypoglycemia; however, it did not occur in a time- or dose-dependent manner. Routine monitoring of blood glucose levels in newborns exposed to α/β- and β-blockers is essential.

Abstract
During normal pregnancy, blood volume increases by nearly two liters. Distinctively, the absence coupled with the extreme extent regarding the volume expansion, are likely accompanied with pathological conditions. Undoubtedly, preeclampsia, defined as the appearance of hypertension and organ deficiency, such as proteinuria during the second half of pregnancy, is not a homogenous disease. Clinically speaking, two main types of preeclampsia can be distinguished, in which a marked difference between them is vascular condition, and consequently, the blood volume. The "classic" preeclampsia, as a two-phase disease, described in the first, latent phase, in which, placenta development is diminished. Agents from this malperfused placenta generate a maternal disease, the second phase, in which endothelial damage leads to hypertension and organ damage due to vasoconstriction and thrombotic microangiopathy. In this hypovolemia-associated condition, decreasing platelet count, signs of hemolysis, renal and liver involvement are characteristic findings; proteinuria is marked and increasing. In the terminal phase, visible edema develops due to increasing capillary transparency, augmenting end-organ damages. "Classic" preeclampsia is a severe and quickly progressing condition with placental insufficiency and consequent fetal growth restriction and oligohydramnios. The outcome of this condition often leads to fetal hypoxia, eclampsia or placental abruption. The management is limited to a diligent prolongation of pregnancy to accomplish improved neonatal pulmonary function, careful diminishing high blood pressure, and delivery induction in due time. The other subtype, associated with relaxed vasculature and high cardiac output, is a maternal disease, in which obesity is an important risk factor since predisposes to enhanced water retention, hypertension, and a weakened endothelial dysfunction. Initially, enhanced water retention leads to lowered extremity edema, which oftentimes progresses to a generalized form and hypertension. In several cases, proteinuria appears most likely due to tissue edema. This condition already fully meets preeclampsia criteria. Laboratory alterations, including proteinuria, are modest and platelet count remains within the normal range. Fetal weight is also normal or frequently over average due to enhanced placental blood supply. It is very likely, further water retention leads to venous congestion, a parenchyma stasis, responsible for ascites, eclampsia, or placental abruption. During the management of this hypervolemia-associated preeclampsia, the administration of diuretic furosemide treatment seemingly offers promise.

Abstract
BACKGROUND Several studies have reported an association between perinatal complications and the severity of the hypertensive disease. The increasing number of pregnancies complicated by hypertension and the small assurance about the perinatal effects of hypertensive drug use during pregnancy involves the need of studying the better management of hypertensive mothers. OBJECTIVE To evaluate the association between maternal use of antihypertensive drugs and maternal and neonatal outcomes in women with chronic hypertension. STUDY DESIGN We conducted a population-based study including all deliveries of hypertensive women that occurred between 2007-2017 in the Lombardy region, Italy. We evaluated the risk of several maternal and neonatal outcomes among women who filled antihypertensive prescriptions within the 20th week of gestation. Propensity score stratification was used to account for key potential confounders. RESULTS Out of 5,553 pregnancies, 2,138 were exposed to antihypertensive treatment. With respect to no-users, users of antihypertensive drugs showed an increased risk of preeclampsia (RR:1.68, 95%CI:1.42-1.99), low birth weight (1.30,1.14-1.48), and preterm birth (1.25,1.11-1.42). These results were consistent in a range of sensitivity and subgroup analyses. CONCLUSION Early exposure to antihypertensive drugs in the first 20 weeks of gestation was associated with an increased risk of preeclampsia, low birth weight, and preterm birth.

Abstract
OBJECTIVES To explore the impact of anti-hypertensive treatment of pregnancy-induced hypertension on foetal growth and hemodynamics in women with pre-existing diabetes. METHODS A prospective cohort study of 247 consecutive pregnant women with pre-existing diabetes (152 type 1 diabetes; 95 type 2 diabetes), where tight anti-hypertensive treatment was initiated and intensified (mainly with methyldopa) when office blood pressure (BP) ≥135/85 mmHg and home BP ≥130/80 mmHg. Foetal growth was assessed by ultrasound at 27, 33 and 36 weeks and foetal hemodynamics were assessed by ultrasound Doppler before and 1-2 weeks after initiation of anti-hypertensive treatment. RESULTS In 215 initially normotensive women, anti-hypertensive treatment for pregnancy-induced hypertensive disorders was initiated in 42 (20%), whilst 173 were left untreated. Chronic hypertension was present in 32 (13%). Anti-hypertensive treatment for pregnancy-induced hypertensive disorders was not associated with foetal growth deviation (linear mixed model, p = 0.681). At 27 weeks, mainly before initiation of anti-hypertensive treatment, the prevalence of small foetuses with an estimated foetal weight <10th percentile was 12% in women initiating anti-hypertensive treatment compared with 4% in untreated women (p = 0.054). These numbers were close to the prevalence of birth weight ≤10th percentile (small for gestational age (SGA)) (17% vs. 4%, p = 0.003). Pulsatility index in the umbilical and middle cerebral artery remained stable after the onset of anti-hypertensive treatment in a representative subgroup (n = 12, p = 0.941 and p = 0.799, respectively). CONCLUSION There is no clear indication that antihypertensive treatment causes harm in this particular at-high-risk group of pregnant women with diabetes, such that a larger well-designed study to determine the value of tight antihypertensive control would be worthwhile.

Abstract
Paragangliomas are rare neuroendocrine neoplasms which are often catecholamine-secreting and associated with familial syndromes. Described here are three women with a variety of pathology: isolated secretory paraganglioma diagnosed in pregnancy, secretory metastatic paraganglioma in pregnancy and non-secretory metastatic paraganglioma in pregnancy. Whilst paragangliomas are associated with morbidity and mortality during pregnancy, good maternal and fetal outcomes can be achieved through individualised care within the context of a multidisciplinary team.

Abstract
Chronic hypertension complicates 1% to 2% of pregnancies, and it is increasingly common. Women with chronic hypertension are an easily recognized group who are in touch with a wide variety of healthcare providers before, during, and after pregnancy, mandating that chronic hypertension in pregnancy be within the scope of many practitioners. We reviewed recent data on management to inform current care and future research. This study is a narrative review of published literature. Compared with normotensive women, women with chronic hypertension are at an increased risk of maternal and perinatal complications. Women with chronic hypertension who wish to be involved in their care can do by measuring blood pressure at home. Accurate devices for home blood pressure monitoring are now readily available. The diagnostic criteria for superimposed preeclampsia remain problematic because most guidelines continue to include deteriorating blood pressure control in the definition. It has not been established how angiogenic markers may aid in confirmation of the diagnosis of superimposed preeclampsia when suspected, over and above information provided by routinely available clinical data and laboratory results. Although chronic hypertension is a strong risk factor for preeclampsia, and aspirin decreases preeclampsia risk, the effectiveness specifically among women with chronic hypertension has been questioned. It is unclear whether calcium has an independent effect in preeclampsia prevention in such women. Treating hypertension with antihypertensive therapy halves the risk of progression to severe hypertension, thrombocytopenia, and elevated liver enzymes, but a reduction in preeclampsia or serious maternal complications has not been observed; however, the lack of evidence for the latter is possibly owing to few events. In addition, treating chronic hypertension neither reduces nor increases fetal or newborn death or morbidity, regardless of the gestational age at which the antihypertensive treatment is started. Antihypertensive agents are not teratogenic, but there may be an increase in malformations associated with chronic hypertension itself. At present, blood pressure treatment targets used in clinics are the same as those used at home, although blood pressure values tend to be inconsistently lower at home among women with hypertension. Although starting all women on the same antihypertensive medication is usually effective in reducing blood pressure, it remains unclear whether there is an optimal agent for such an approach or how best to use combinations of antihypertensive medications. An alternative approach is to individualize care, using maternal characteristics and blood pressure features beyond blood pressure level (eg, variability) that are of prognostic value. Outcomes may be improved by timed birth between 38 0/7 and 39 6/7 weeks' gestation based on observational literature; of note, confirmatory trial evidence is pending. Postnatal care is facilitated by the acceptability of most antihypertensives (including angiotensin-converting enzymes inhibitors) for use in breastfeeding. The evidence base to guide the care of pregnant women with chronic hypertension is growing and aligning with international guidelines. Addressing outstanding research questions would inform personalized care of chronic hypertension in pregnancy.

Mulder E, Ghossein-Doha C, Appelman E, van Kuijk S, Smits L, van der Zanden R, van Drongelen J, Spaanderman M. Study protocol for the randomized controlled EVA (early vascular adjustments) trial: tailored treatment of mild hypertension in pregnancy to prevent severe hypertension and preeclampsia. BMC Pregnancy Childbirth 2020; 20:775. [PMID: 33308198 PMCID: PMC7733247 DOI: 10.1186/s12884-020-03475-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Accepted: 12/03/2020] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND In contrast to severe gestational hypertension, it is questioned whether antihypertensive medication for mild to moderate gestational hypertension prevents adverse maternal and offspring outcomes. Hypertensive drugs halve the risk of severe hypertension, but do not seem to prevent progression to preeclampsia or reduce the risk of complications in offspring. In fact, beta-blockers, a first line therapy option, are suspected to impair foetal growth. Disappointing effects of antihypertensive medication can be anticipated when the pharmacological mode of action does not match the underlying haemodynamic imbalance. Hypertension may result from 1) high cardiac output, low vascular resistance state, in which beta blockade is expected to be most effective, or 2) low cardiac output, high vascular resistance state where dihydropyridine calcium channel blockers or central-acting alpha agonists might be the best corrective medication. In the latter, beta-blockade might be maternally ineffective and even contribute to impaired foetal growth by keeping cardiac output low. We propose a randomized controlled trial to determine whether correcting the haemodynamic imbalance in women with mild to moderate hypertension reduces the development of severe hypertension and/or preeclampsia more than non-pharmacological treatment does, without alleged negative effects on foetal growth. METHODS Women diagnosed with mild to moderate hypertension without proteinuria or signs of other organ damage before 37 weeks of pregnancy are invited to participate in this randomized controlled trial. Women randomized to the intervention group will be prescribed tailored antihypertensive medication, using a simple diagnostic and treatment algorithm based on the mean arterial pressure/heart rate ratio, which serves as an easy-to-determine proxy for maternal circulatory state. Women randomized to the control group will receive non-pharmacological standard care according to national and international guidelines. In total, 208 women will be randomized in a 1:1 ratio. The primary outcome is progression to severe hypertension and preeclampsia and the secondary outcomes are adverse maternal and neonatal outcomes. DISCUSSION This trial will provide evidence of whether tailoring treatment of mild to moderate gestational hypertension to the individual haemodynamic profile prevents maternal disease progression. TRIAL REGISTRATION NCT02531490 , registered on 24 August 2015.

Abstract
KEY POINTS Maternal hypertension is associated with increased rates of pregnancy pathologies, including fetal growth restriction, due at least in part to reductions in nitric oxide (NO) bioavailability and associated vascular dysfunction. Dietary nitrate supplementation, from beetroot juice (BRJ), has been shown to increase NO bioavailability and improve cardiovascular function in both preclinical and clinical studies. This study is the first to investigate effects of dietary nitrate supplementation in a pregnant animal model. Importantly, the effects of nitrate-containing BRJ were compared with both 'placebo' (nitrate-depleted) BRJ as well as water to control for potential nitrate-independent effects. Our data show novel, nitrate-independent effects of BRJ to lower blood pressure and improve vascular function in endothelial nitric oxide synthase knockout (eNOS-/- ) mice. These findings suggest potential beneficial effects of BRJ supplementation in pregnancy, and emphasize the importance of accounting for nitrate-independent effects of BRJ in study design and interpretation. ABSTRACT Maternal hypertension is associated with adverse pregnancy outcomes, including fetal growth restriction (FGR), due in part to reductions in nitric oxide (NO) bioavailability. We hypothesized that maternal dietary nitrate administration would increase NO bioavailability to reduce systolic blood pressure (SBP), improve vascular function and increase fetal growth in pregnant endothelial NO synthase knockout (eNOS-/- ) mice, which exhibit hypertension, endothelial dysfunction and FGR. Pregnant wildtype (WT) and eNOS-/- mice were supplemented with nitrate-containing beetroot juice (BRJ+) from gestational day (GD) 12.5. Control mice received an equivalent dose of nitrate-depleted BRJ (BRJ-) or normal drinking water. At GD17.5, maternal SBP was measured; at GD18.5, maternal nitrate/nitrite concentrations, uterine artery (UtA) blood flow and endothelial function were assessed, and pregnancy outcomes were determined. Plasma nitrate concentrations were increased in both WT and eNOS-/- mice supplemented with BRJ+ (P < 0.001), whereas nitrite concentrations were increased only in eNOS-/- mice (P < 0.001). BRJ- did not alter nitrate/nitrite concentrations. SBP was lowered and UtA endothelial function was enhanced in eNOS-/- mice supplemented with either BRJ+ or BRJ-, indicating nitrate-independent effects of BRJ. Improvements in endothelial function in eNOS-/- mice were abrogated in the presence of 25 mm KCl, implicating enhanced EDH signalling in BRJ- treated animals. At GD18.5, eNOS-/- fetuses were significantly smaller than WT animals (P < 0.001), but BRJ supplementation did not affect fetal weight. BRJ may be a beneficial intervention in pregnancies associated with hypertension, endothelial dysfunction and reduced NO bioavailability. Our data showing biological effects of non-nitrate components of BRJ have implications for both interpretation of previous findings and in the design of future clinical trials.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) affects up to 1 in 1000 people. The disease is characterized by the progressive development of cysts throughout the renal parenchyma due to inherited pathogenic variants in genes including PKD1 or PKD2 and eventually leads to gradual loss of renal function, along with manifestations in other organ systems such as hepatic cysts and intracranial aneurysms. ADPKD management has advanced considerably in recent years due to genetic testing availability, pre-implantation genetic diagnosis technology and new therapeutic agents. Renal disease in pregnancy is recognised as an important risk factor for adverse maternal and fetal outcome. Women with ADPKD and health professionals face multiple challenges in optimising outcomes during the pre-pregnancy, pregnancy and post-partum periods.

Abstract
PURPOSE OF REVIEW This review discusses the mortality and morbidity of hypertensive disorders of pregnancy (HDP) and the current diagnostic thresholds. It then explores measurement of variability in blood pressure (BP) during pregnancy as an opportunity to identify women at high risk of cardiovascular disease (CVD) later in life. RECENT FINDINGS HDP is known to be associated with increased risk of long-term CVD. Current CVD prognostic tools do not incorporate a history of HDP given a lack of improved risk discrimination. However, HDP diagnostic criteria are currently based on a binary threshold, and there is some evidence for the use of variability in BP throughout gestation as a marker of CVD risk. HDP increases long-term risk of CVD. Future studies investigating changes in diagnostic criteria, including the use of BP variability, may improve long-term CVD risk prediction and be incorporated into future risk assessment tools.

Abstract
Malnutrition has historically been researched and addressed within two distinct silos, focusing either on undernutrition, food insecurity, and micronutrient deficiencies, or on overweight, obesity, and dietary excess. However, through rapid global nutrition transition, an increasing proportion of individuals are exposed to different forms of malnutrition during the life course and have the double burden of malnutrition (DBM) directly. Long-lasting effects of malnutrition in early life can be attributed to interconnected biological pathways, involving imbalance of the gut microbiome, inflammation, metabolic dysregulation, and impaired insulin signalling. Life-course exposure to early undernutrition followed by later overweight increases the risk of non-communicable disease, by imposing a high metabolic load on a depleted capacity for homoeostasis, and in women increases the risk of childbirth complications. These life-course trajectories are shaped both by societal driving factors-ie, rapidly changing diets, norms of eating, and physical activity patterns-and by broader ecological factors such as pathogen burden and extrinsic mortality risk. Mitigation of the DBM will require major societal shifts regarding nutrition and public health, to implement comprehensive change that is sustained over decades, and scaled up into the entire global food system.

Abstract
Intracranial hemorrhage and stroke are primary causes of maternal mortality in pregnancies affected by hypertensive disorders. As such antihypertensive therapy plays a crucial role in the management of severe hypertension. However, the target level to achieve the best outcome for both - mother and fetus - is still unclear. Moreover, given the lack of well-designed randomized controlled trials with standardized key outcomes, the current choice of antihypertensive medications depends rather on clinicians' preference. Furthermore, data on long-term outcomes of offspring is not available. Therefore, there is an urgent need for randomized trials comparing different anti-hypertensive options to address efficacy and safety questions.

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

Abstract
INTRODUCTION In women with type 1 diabetes mellitus (T1DM), pregnancy is associated with a potential risk of maternal, foetal and neonatal outcomes. Stringent metabolic control is required to improve these outcomes. AREAS COVERED In this review, the authors summarise the current evidence from studies on the pharmacological therapy and on monitoring of T1DM during pregnancy. The authors also discuss the use of new technologies to improve therapeutic management and patient compliance. EXPERT OPINION Pre-conception counselling is essential in T1DM to minimise pregnancy risks. Pregnancy in T1DM is always considered a high-risk pregnancy. During pregnancy, the target haemoglobin A1C (HbA1c) is near-normal at <6%, without excessive hypoglycaemia. Strict control of pre- and post-prandial glucose is also required. Human soluble insulin, neutral protamine Hagedorn and the quick-acting insulin analogues aspart and lispro are widely used. Insulin is administered either as a basal-bolus regimen or by continuous subcutaneous insulin infusion. Careful and strict glucose monitoring is also needed during labour and delivery, including caesarean section. Moreover, the control of retinopathy, hypertension, nephropathy, hyper- and hypothyroidism is required. Post-partum, insulin requirements decrease, and less stringent glycaemic control is pursued, to avoid hypoglycaemias. Finally, breastfeeding is recommended and should be encouraged.

Abstract
Hypertension complicates up to 10% of pregnancies worldwide. Pregnancy hypertension is defined as systolic blood pressure (BP) equal to or greater than 140 mm Hg or diastolic BP equal to or greater than 90 mm Hg, usually on the basis of measurements in office/clinic settings and using various BP devices. Hypertensive disorders of pregnancy are classified into (1) chronic hypertension diagnosed before pregnancy or before 20 weeks' gestation, (2) gestational hypertension diagnosed at equal to or greater than 20 weeks, or (3) preeclampsia, defined restrictively as gestational hypertension with proteinuria or broadly as gestational hypertension with proteinuria or an end-organ manifestation consistent with preeclampsia. Absolute BP values equal to or greater than 140/90 mm Hg are associated with increased maternal and perinatal risks, particularly with preeclampsia. This review focuses on antihypertensive therapy of hypertensive disorders of pregnancy as a specific management strategy. Underpinning this therapy is the need for accurate measurement of BP, agreed-upon classification of pregnancy hypertension, agreed-upon BP thresholds for enhanced surveillance and antihypertensive treatment, and collaborative teamwork in management. Challenges relate to the methodology of studies on which care is based, as well as aspects of the care itself, particularly the unregulated use of home BP monitoring. Pitfalls include the unsubstantiated belief that nifedipine and magnesium sulfate cannot be used together and the perception that severe hypertension and nonsevere hypertension are separate entities rather than lying along a spectrum of BP values. The following must be addressed by future research: guidance for nuanced care as women transition between severe and nonsevere hypertension, personalized antihypertensive therapy, and incorporation of women's values into research priorities and clinical practice when antihypertensive care is chosen.

Abstract
Chronic hypertension in pregnancy is associated with significant adverse pregnancy outcomes, increasing the risk of pre-eclampsia, fetal growth restriction and preterm birth. Dietary nitrate, abundant in green leafy vegetables and beetroot, is reduced in vivo to nitrite and subsequently nitric oxide, and has been demonstrated to lower blood pressure, improve vascular compliance and enhance blood flow in non-pregnant humans and animals. The primary aims of this study were to determine the acceptability and efficacy of dietary nitrate supplementation, in the form of beetroot juice, to lower blood pressure in hypertensive pregnant women. In this double-blind, placebo-controlled feasibility trial, 40 pregnant women received either daily nitrate supplementation (70 mL beetroot juice, n = 20) or placebo (70 mL nitrate-depleted beetroot juice, n = 20) for 8 days. Blood pressure, cardiovascular function and uteroplacental blood flow was assessed at baseline and following acute (3 h) and prolonged (8 days) supplementation. Plasma and salivary samples were collected for analysis of nitrate and nitrite concentrations and acceptability of this dietary intervention was assessed based on questionnaire feedback. Dietary nitrate significantly increased plasma and salivary nitrate/nitrite concentrations compared with placebo juice (p < 0.001), with marked variation between women. Compared with placebo, there was no overall reduction in blood pressure in the nitrate-treated group; however there was a highly significant correlation between changes in plasma nitrite concentrations and changes in diastolic blood pressure in the nitrate-treated arm only (r = -0.6481; p = 0.0042). Beetroot juice supplementation was an acceptable dietary intervention to 97% of women. This trial confirms acceptability and potential efficacy of dietary nitrate supplementation in pregnant women. Conversion of nitrate to nitrite critically involves oral bacterial nitrate reductase activities. We speculate that differences in efficacy of nitrate supplementation relate to differences in the oral microbiome, which will be investigated in future studies.

Abstract
Due to its short-term consequences on perinatal outcome, preeclampsia has been long regarded as an obstetrical disease, strictly confined to a management by OB/GYNs. It has been now widely accepted that preeclampsia is most a systemic inflammatory and systemic vascular disease during pregnancy and then a lifelong risk factor for subsequent cardiovascular event in women's life. The aim of this review is to propose an overview in the current state-of-art in definition, early identification and management of preeclampsia. We will also discuss the growing evidence that support that cardiologists must be fully involved in screening and prevention of preeclampsia during pregnancy and beyond in the subsequent medical follow-up of women who have experienced a preeclampsia.

Influence of Gestational Age at Initiation of Antihypertensive Therapy: Secondary Analysis of CHIPS Trial Data (Control of Hypertension in Pregnancy Study). Hypertension 2018; 71:1170-1177. [PMID: 29686009 PMCID: PMC5959211 DOI: 10.1161/hypertensionaha.117.10689] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2017] [Revised: 12/27/2017] [Accepted: 03/13/2018] [Indexed: 11/16/2022]
Abstract
Supplemental Digital Content is available in the text. For hypertensive women in CHIPS (Control of Hypertension in Pregnancy Study), we assessed whether the maternal benefits of tight control could be achieved, while minimizing any potentially negative effect on fetal growth, by delaying initiation of antihypertensive therapy until later in pregnancy. For the 981 women with nonsevere, chronic or gestational hypertension randomized to less-tight (target diastolic blood pressure, 100 mm Hg), or tight (target, 85 mm Hg) control, we used mixed-effects logistic regression to examine whether the effect of less-tight (versus tight) control on major outcomes was dependent on gestational age at randomization, adjusting for baseline factors as in the primary analysis and including an interaction term between gestational age at randomization and treatment allocation. Gestational age was considered categorically (quartiles) and continuously (linear or quadratic form), and the optimal functional form selected to provide the best fit to the data based on the Akaike information criterion. Randomization before (but not after) 24 weeks to less-tight (versus tight) control was associated with fewer babies with birth weight <10th centile (Pinteraction=0.005), but more preterm birth (Pinteraction=0.043), and no effect on perinatal death or high-level neonatal care >48 hours (Pinteraction=0.354). For the mother, less-tight (versus tight) control was associated with more severe hypertension at all gestational ages but particularly so before 28 weeks (Pinteraction=0.076). In women with nonsevere, chronic, or gestational hypertension, there seems to be no gestational age at which less-tight (versus tight) control is the preferred management strategy to optimize maternal or perinatal outcomes.

Abstract
AIMS To identify early clinical, modifiable risk factors for preeclampsia present at first antenatal visit and assess the prevalence of pregnancy-related hypertensive disorders in women with pre-existing diabetes treated with tight glycemic and blood pressure (BP) control. METHODS A population-based cohort study of 494 women with pre-existing diabetes (307 and 187 women with type 1 and type 2 diabetes, respectively), included at their first antenatal visit from 2012 to 2016. The prevalence of chronic hypertension (without diabetic nephropathy or microalbuminuria), gestational hypertension and preeclampsia was recorded. Diabetic microangiopathy included presence of nephropathy, microalbuminuria and/or retinopathy. Treatment target was BP <135/85 mmHg. RESULTS HbA1c was 6.9 ± 2.4% (50 ± 12 mmol/mol) at first antenatal visit and 6.0 ± 0.6% (43 ± 6 mmol/mol) before delivery with no differences between women with type 1 and type 2 diabetes. At the first antenatal visit, the prevalence of microalbuminuria was 6% (6% vs. 6%), nephropathy 2% (1% vs. 2%) and chronic hypertension 6% (3% vs. 10%, p = 0.03). Gestational hypertension developed in 8% (9% vs. 6%) and preeclampsia developed in 8% (9% vs. 7%). Presence of diabetic microangiopathy (adjusted odds ratio (OR) 4.35 (confidence interval 2.12-8.93)) and diastolic BP (adjusted OR 1.72 per 10 mmHg (1.05-2.82)) at the first antenatal visit were independent risk factors for preeclampsia. CONCLUSIONS At the first antenatal visit, diastolic BP was the only independent, potentially modifiable risk factor for preeclampsia in women with pre-existing diabetes in the context of tight glycemic and BP control. One out of four women had hypertensive disorders during pregnancy.

Chronic hypertension: first-trimester blood pressure control and likelihood of severe hypertension, preeclampsia, and small for gestational age. Am J Obstet Gynecol 2018; 218:337.e1-337.e7. [PMID: 29305253 DOI: 10.1016/j.ajog.2017.12.235] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2017] [Revised: 12/09/2017] [Accepted: 12/21/2017] [Indexed: 01/23/2023]
Abstract
BACKGROUND There is extensive evidence that prepregnancy chronic hypertension is associated with a high risk of development of severe hypertension and preeclampsia and birth of small-for-gestational-age neonates. However, previous studies have not reported whether antihypertensive use, blood pressure control, or normalization of blood pressure during early pregnancy influences the rates of these pregnancy complications. OBJECTIVE The purpose of this study was to stratify women with prepregnancy chronic hypertension according to the use of antihypertensive medications and level of blood pressure control at the first hospital visit during the first trimester of pregnancy and to examine the rates of severe hypertension, preeclampsia, and birth of small-for-gestational-age neonates according to such stratification. STUDY DESIGN We conducted a prospective study of 586 women with prepregnancy chronic hypertension, in the absence of renal or liver disease, that was booked at a dedicated clinic for the management of hypertension in pregnancy. The patients had singleton pregnancies and were subdivided according to findings in their first visit: group 1 (n=199), blood pressure <140/90 mm Hg without antihypertensive medication; group 2 (n=220), blood pressure <140/90 mm Hg with antihypertensive medication; and group 3 (n=167), systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg, despite antihypertensive medication. In the subsequent management of these pregnancies, our policy was to maintain the blood pressure at 130-140/80-90 mm Hg with the use of antihypertensive medication; antihypertensive drugs were stopped if the blood pressure was persistently <130/80 mm Hg. The outcome measures were severe hypertension (systolic blood pressure ≥160 mm Hg and/or diastolic blood pressure ≥110 mm Hg), preterm and term preeclampsia (in addition to hypertension at least 1 of renal involvement, liver impairment, neurologic complications, or thrombocytopenia), and birth of small-for-gestational-age neonates (birthweight <5th percentile for gestational age). The incidence of these complications was compared in the 3 strata. RESULTS The median gestational age at presentation was 10.0 weeks (interquartile range, 9.1-11.0 weeks). In groups 2 and 3, compared with group 1, there was a significantly higher body mass index, incidence of black racial origin, and history of preeclampsia in a previous pregnancy. There was a significant increase from group 1 to group 3 in the incidence of severe hypertension (10.6%, 22.2%, and 52.1%), preterm preeclampsia with onset at <37 weeks of gestation (7.0%, 15.9%, and 20.4%), and small for gestational age (13.1%, 17.7%, and 21.1%), but not term preeclampsia with onset at ≥37 weeks of gestation (9.5%, 9.1%, and 6.6%). CONCLUSIONS In women with prepregnancy chronic hypertension, the rates of development of severe hypertension, preterm preeclampsia, and small for gestational age are related to the use of antihypertensive medications and the level of blood pressure control at the first hospital visit during the first trimester of pregnancy.

Abstract
AIM To compare the blood pressure (BP) lowering effects of labetalol and nifedipine modified release (MR) in hypertensive pregnant women. We also investigated the effect on the heart rate (HR) and determined the proportion of time spent in target. METHODS This was an exploratory study. Women with chronic hypertension taking either labetalol or nifedipine were offered 24-h ambulatory blood pressure monitoring (ABPM). Sleep, wake and drug ingestion times were self-reported. An indirect response model was used to analyse the systolic BP (SBP), diastolic BP (DBP) and HR time-series; the effect of gestation and type of drug was evaluated. RESULTS Forty-eight women were recruited: 24 in each group. There was no difference in clinical characteristics. In women taking nifedipine there was a positive association between the dose of nifedipine and pre-dose BP p = .002, this was not present in the labetalol group. There was a difference between the drug effects on both the SBP and DBP time-series (p = .014). In comparison to labetalol, there was less variation in day time BP in those women prescribed nifedipine. Women on labetalol spent a larger proportion of time with their DBP below target (<80 mmHg). The HR dynamics were qualitatively different, a stimulatory effect was found with nifedipine compared to an inhibitory effect with labetalol. CONCLUSION There are significant and important differences between the BP lowering effects of nifedipine and labetalol. A large randomised control trial is required to investigate the relationship between BP variability and time in target on pregnancy outcomes.

Abstract
OBJECTIVE To examine whether in patients with CH and mild to moderate hypertension the level of control of blood pressure during pregnancy has a beneficial or adverse effect on the risk of PE or SGA. METHODS We performed a systematic review and meta-analysis of randomized controlled trials of patients with mild to moderate CH in pregnancy that reported the impact of different levels of control of blood pressure on the risk of PE or SGA. We completed a literature search through PubMed, Embase, Cinahl, Web of science, Cochrane CENTRAL Library Relative risks with random effect were calculated with their 95% confidence intervals (95%CI). RESULTS Six trials including 495 participants provided data on blood pressure (BP) after entry to the study. Four studies compared antihypertensive agents to no treatment and two studies compared antihypertensive agents to placebo. All trials were conducted between 1976 and 1990 and were considered to be at high risk of bias. There was high heterogeneity between studies for mean arterial pressure (MAP) after randomization (I2 = 87%) and SGA (I2 = 60%), but not for PE (I2 = 0%). There were large differences between studies in the inclusion criteria, antihypertensive regimens, targets of therapy, and gestational age range at entry to the trials. In women receiving antihypertensive therapy, compared to those receiving placebo or no treatment, the MAP after entry to the trial was significantly lower (mean difference -4.2 mmHg, 95%CI -6.6 to -1.8; p = .006). However, there was no significant reduction in the risk of PE (relative risks (RR) 1.03, 95%CI 0.63-1.68; p = .90) or SGA (RR 1.01, 95%CI 0.35-2.93; p = .99). CONCLUSIONS The findings of the meta-analysis suggest that lowering the blood pressure by antihypertensive medication in women with mild to moderate hypertension in the context of CH has no significant effect on the risk of SGA or PE.

Abstract
OBJECTIVE To examine the effect of furosemide on hypertension and edema in patients with pre-eclampsia experiencing high cardiac output. METHODS The present cohort study enrolled patients with pre-eclampsia who were admitted to the pregnancy pathology unit of the Department of Obstetrics and Gynecology, University of Pécs, Hungary, between January 1 and December 31, 2015. Eligible patients had singleton pregnancies with no fetal anomalies, high blood volume, visible edema, and a hematocrit concentration below 37 L/L. Blood pressure was measured and impedance cardiography was used to determine cardiac output for all patients before they received a 40-mg dose of furosemide; after 60 minutes blood pressure and cardiac output were measured again. RESULTS The study enrolled 14 patients. Lower cardiac output (P=0.002), systolic blood pressure (P=0.002), and diastolic blood pressure (P=0.002) were recorded after furosemide administration, with patient heart rates remaining stable. CONCLUSION The heart-rate stability suggests that the change of cardiac output was due to a decrease in blood volume. These data suggest that diuretics could be useful in the management of late-onset pre-eclampsia, indicating that an increase in water retention could play a role in the development of late-onset pre-eclampsia.

Abstract
Preeclampsia is a common pregnancy specific disease, that presents with hypertension and a variety of organ failures, including malfunction of kidneys, liver and lungs. At present, the only definitive treatment of preeclampsia is end the pregnancy and deliver the neonate and placenta. For women with mild preeclampsia in the preterm phase of pregnancy, expectant management is generally indicated to improve fetal maturity, often requiring maternal medical treatment. Last decades, more evidence is available that the underlying mechanism of preeclampsia, endothelial disease, is not limited to pregnancy but increases cardiovascular risk in later life. In this review, we present the most recent insight in preeclampsia with focus on impact on the fetus, short and long-term outcome of offspring's, and long-term outcome of women with a history of preeclampsia.

Abstract
BACKGROUND Treatment of nonsevere hypertension during pregnancy is controversial. Sildenafil is a phosphodiesterase inhibitor that potentiates nitric oxide by promoting vasodilation. Nitric oxide plays a vital role in mediating the vascular adaptations during pregnancy. OBJECTIVE The objective of the study was to determine whether treatment with sildenafil during pregnancy would lower maternal systolic blood pressure without adversely affecting fetal growth. STUDY DESIGN Females with nonsevere hypertension (endothelial nitric oxide synthase(+/-)) were cross-bred with normotensive wild-type males. At gestational day 1, pregnant dams were randomized to either sildenafil (0.4 mg/mL per day, comparable dose used in human pregnancy) or water for 3 weeks. Four groups were then generated: wild type (n = 7), wild type-sildenafil (n = 11), endothelial nitric oxide synthase(+/-) (n = 8), and endothelial nitric oxide synthase(+/-)sildenafil (n = 7). On gestational day 18, systolic blood pressure was measured. Dams were killed, fetal and placental weights were obtained, and carotid arteries were dissected to measure in vitro vascular reactivity with a wire-myography system. Responses to phenylephrine, L-NG-nitroarginine methyl ester, acetylcholine, and sodium nitroprusside were studied. RESULTS Mean systolic blood pressure was elevated in the endothelial nitric oxide synthase(+/-) dams compared with wild-type controls (P = .03). Treatment with sildenafil decreased systolic blood pressure in the endothelial nitric oxide synthase(+/-)-treated dams compared with nontreated endothelial nitric oxide synthase(+/-) dams (P = .03). No differences were seen in the wild-type dams with or without sildenafil (P = .47). Fetuses from endothelial nitric oxide synthase(+/-) dams were smaller compared with wild-type controls (P < .001); however, when these endothelial nitric oxide synthase(+/-) dams were treated with sildenafil, fetal weight increased compared with the nontreated endothelial nitric oxide synthase(+/-) group (P < .001). No difference were seen in wild-type groups treated or not treated with sildenafil (P = .41). Placental weights were not significantly different among groups (endothelial nitric oxide synthase(+/-)sildenafil vs endothelial nitric oxide synthase(+/-) [P = .48]; wild-type-sildenafil vs wild type [P = .52]). Maximal vascular contraction induced by phenylephrine was blunted in endothelial nitric oxide synthase(+/-) dams treated with sildenafil compared with nontreated endothelial nitric oxide synthase(+/-) dams (P < .01). No change in contractile response was seen in wild-type groups treated or not treated (P = .53). When vessels were preincubated with L-NG-nitroarginine methyl ester, the contractile responses were similar among all groups (P = .54). In addition, maximal vascular relaxation induced by acetylcholine was improved in the endothelial nitric oxide synthase(+/-) dams treated with sildenafil compared with endothelial nitric oxide synthase(+/-) nontreated dams (P < .01). No change in relaxation response was seen in wild-type groups treated or not treated (P = .62). Sodium nitroprusside did not change the contractile response in any of the groups (P = .31). CONCLUSION Pregnant dams deficient in endothelial nitric oxide synthase, a nonsevere hypertensive murine model, treated with sildenafil had lower maternal systolic blood pressure, increased fetal growth, and improvement in vascular reactivity. Treatment with sildenafil may be beneficial in pregnancies complicated by nonsevere hypertension.

Abstract
In the first 6 months of pregnancy, the primary goal of antihypertensive treatment is to prevent the complications of severe hypertension. Initiation of antihypertensive drug treatment is recommended in pregnant women with severe hypertension (blood pressure>160/110mmHg). Initiation of antihypertensive drug treatment should also be considered in pregnant women at high cardiovascular risk (diabetes, chronic kidney disease, personal history of cardiovascular disease) with moderate hypertension (blood pressure between 140-159/90-109mmHg). A systolic blood pressure goal<160 and a diastolic blood pressure goal between 85 and 100mmHg is recommended in pregnancy. Labetalol, nifedipine, nicardipine and alphamethyldopa should be considered preferential antihypertensive drugs in pregnancy. Salt restriction, physical exercise and weight loss have not demonstrated any effect in the prevention of preeclampsia and serious maternal complications of hypertension.

Abstract
Women with type 1 diabetes (T1DM) have unique needs during the preconception, pregnancy, and postpartum periods. Preconception counseling is essential for women with T1DM to minimize pregnancy risks. The goals of preconception care should be tight glycemic control with a hemoglobin A1c (A1C) < 7 % and as close to 6 % as possible, without significant hypoglycemia. This will lower risks of congenital malformations, preeclampsia, and perinatal mortality. The safety of medications should be assessed prior to conception. Optimal control of retinopathy, hypertension, and nephropathy should be achieved. During pregnancy, the goal A1C is near-normal at <6 %, without excessive hypoglycemia. There is no clear evidence that continuous subcutaneous insulin infusion (CSII) versus multiple daily injections (MDI) is superior in achieving the desired tight glycemic control of T1DM during pregnancy. Data regarding continuous glucose monitoring (CGM) in pregnant women with T1DM is conflicting regarding improved glycemic control. However, a recent CGM study does provide some distinct patterns of glucose levels associated with large for gestational age infants. Frequent eye exams during pregnancy are essential due to risk of progression of retinopathy during pregnancy. Chronic hypertension treatment goals are systolic blood pressure 110-129 mmHg and diastolic blood pressure 65-79 mmHg. Labor and delivery target plasma glucose levels are 80-110 mg/dl, and an insulin drip is recommended to achieve these targets during active labor. Postpartum, insulin doses must be reduced and glucoses closely monitored in women with T1DM because of the enhanced insulin sensitivity after delivery. Breastfeeding is recommended and should be highly encouraged due to maternal benefits including increased insulin sensitivity and weight loss and infant and childhood benefits including reduced prevalence of overweight. In this article, we discuss the care of pregnant patients with T1DM.

Abstract
INTRODUCTION Labetalol is one of the most commonly used antihypertensive medications for the treatment of hypertension during pregnancy, an increasingly common and leading cause of maternal mortality and morbidity worldwide. AREAS COVERED The literature reviewed included the 2014 Canadian national pregnancy hypertension guideline and its references. The additional published literature was retrieved through searches of Medline, CINAHL, and The Cochrane Library using appropriate controlled vocabulary (e.g., pregnancy, hypertension, pre-eclampsia, pregnancy toxemias) and key words (e.g., diagnosis, evaluation, classification, prediction, prevention, prognosis, treatment, and postpartum follow-up).Results were restricted to systematic reviews, randomized controlled trials, controlled clinical trials, and observational studies published in French or English, Jan-Mar/14. The unpublished literature was identified by searching websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. We evaluated the impact of interventions on substantive clinical outcomes for mothers and babies. EXPERT OPINION Labetalol is a reasonable choice for treatment of severe or non-severe hypertension in pregnancy. However, we should continue our search for other therapeutic options.

Abstract
As the age of pregnant women and prevalence of obesity and diabetes are increasing, so is the prevalence of medical disorders during pregnancy, particularly hypertension and the associated CKD. Pregnancy can worsen kidney function in women with severe disease, and hypertension puts them at risk for pre-eclampsia and the associated complications. There are no specific guidelines for hypertension management in this population, and tight control will not prevent pre-eclampsia. Women with end-stage kidney disease should be placed on intense dialysis regimens to improve obstetric outcomes, and angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are best avoided. This article will review the rationale for a management plan that includes a multidisciplinary team to discuss risks and develop a plan before conception, antepartum monitoring for maternal and fetal morbidity, individualization of medical management using medications with established records during pregnancy, and balancing the level of blood pressure control proved to protect kidney function against the potential effects that aggressive blood pressure control could have on the fetal-placental unit.

Abstract
BACKGROUND The effects of less-tight versus tight control of hypertension on pregnancy complications are unclear. METHODS We performed an open, international, multicenter trial involving women at 14 weeks 0 days to 33 weeks 6 days of gestation who had nonproteinuric preexisting or gestational hypertension, office diastolic blood pressure of 90 to 105 mm Hg (or 85 to 105 mm Hg if the woman was taking antihypertensive medications), and a live fetus. Women were randomly assigned to less-tight control (target diastolic blood pressure, 100 mm Hg) or tight control (target diastolic blood pressure, 85 mm Hg). The composite primary outcome was pregnancy loss or high-level neonatal care for more than 48 hours during the first 28 postnatal days. The secondary outcome was serious maternal complications occurring up to 6 weeks post partum or until hospital discharge, whichever was later. RESULTS Included in the analysis were 987 women; 74.6% had preexisting hypertension. The primary-outcome rates were similar among 493 women assigned to less-tight control and 488 women assigned to tight control (31.4% and 30.7%, respectively; adjusted odds ratio, 1.02; 95% confidence interval [CI], 0.77 to 1.35), as were the rates of serious maternal complications (3.7% and 2.0%, respectively; adjusted odds ratio, 1.74; 95% CI, 0.79 to 3.84), despite a mean diastolic blood pressure that was higher in the less-tight-control group by 4.6 mm Hg (95% CI, 3.7 to 5.4). Severe hypertension (≥160/110 mm Hg) developed in 40.6% of the women in the less-tight-control group and 27.5% of the women in the tight-control group (P<0.001). CONCLUSIONS We found no significant between-group differences in the risk of pregnancy loss, high-level neonatal care, or overall maternal complications, although less-tight control was associated with a significantly higher frequency of severe maternal hypertension.

Abstract
Objectives: The study aims to evaluate the management, maternal-fetal outcomes, and prescription behavior among inpatients with severe preeclampsia and eclampsia. Materials and Methods: This prospective cohort study in a tertiary referral center was conducted in 164 inpatient pregnant women who fulfilled the inclusion criteria. The study was conducted between November 2005 and February 2007. The patients were followed-up till delivery. Antepartum and intrapartum care and maternal and perinatal outcome were noted. Chief outcome measures were maternal and perinatal mortality and drug use indicators. Results: Median age at delivery of the women was 25 (22-28) years. Majority were suffering from antepartum eclampsia (52.5%), followed by preeclampsia (31%) and postpartum eclampsia (16.5%). Nulliparity (61.6%) was more common in eclampsia, while multiparity in preclamptic group. A total of 48% had preterm delivery. Most presented with headache (50%) and hyperreflexia (29%). Only 15% presented with all three prodromal symptoms and 86% had hypertension. There was increased morbidity, operative intervention, and admission to intensive care unit. Most babies (67%) weighed <2.5 kg and had poor outcome. The maternal mortality was 0.4/1000. Average number of drugs prescribed in patients of preeclampsia, antepartum eclampsia, and postpartum eclampsia were 13.2, 14.9, and 14.2, respectively. Antibiotics (24.6%) were the most common class of the drugs prescribed in all the groups, followed by vitamin and calcium supplements (22.7%) and antihypertensives (13.5%). Most common antihypertensive used were calcium channel blockers and anticonvulsant magnesium sulphate. Conclusions: There was increased maternal and perinatal morbidity. Protocols for the management of eclampsia, including antihypertensive and anticonvulsant therapies, should be available and reviewed regularly to improve the standard of care and reduce the prevalence of this dangerous condition.

Abstract
OBJECTIVE To compare outcomes between elective delivery at 37 weeks of pregnancy and expectant management among pregnant women with mild to moderate chronic hypertension. METHODS In a two-center study, 76 women with mild to moderate chronic hypertension were randomly allocated to planned delivery at 37 completed weeks (group A) or expectant management for spontaneous onset of labor or reaching 41 weeks (group B) between April 2012 and October 2013. Differences were compared by t test, χ(2) test, or Fisher exact test. Odds ratios (ORs) with 95% confidence interval (CIs) were determined. RESULTS There were no differences in superimposed pre-eclampsia (SPE), severe hypertension, preterm delivery, placental abruption, oligohydramnios, intrauterine growth restriction, or perinatal mortality between the groups. Group B had higher gestational age at delivery (P=0.001) and birth weight (P=0.01), but lower cesarean (OR 3.4; 95% CI, 1.2-10.3; P=0.03) and neonatal care unit admission (OR 5.4; 95% CI, 1.4-21.0; P=0.01) rates. More women with SPE were diagnosed before than after 37 weeks in group B (P=0.01). Overall, patients who developed SPE had more adverse pregnancy outcomes than those who did not. CONCLUSION Mild to moderate chronic hypertension could be managed expectantly up to 41 weeks if SPE did not develop.

Abstract
OBJECTIVE To investigate whether antihypertensive classes and specific medications in early pregnancy increase the risk of severe hypospadias and to assess prior associations detected for late-treated and untreated hypertension in the National Birth Defects Prevention Study. METHODS Using telephone interviews from mothers of 2,131 children with severe hypospadias and 5,129 nonmalformed male control children for 1997-2009 births in a population-based case-control study, we estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) with multivariable logistic regression. We adjusted P values to account for multiple testing. RESULTS Forty-eight (2.3%) case and 70 (1.4%) control mothers reported early pregnancy antihypertensive treatment, 45 (2.1%) case and 31 (0.6%) control mothers reported late treatment, and 315 (14.8%) case and 394 (7.7%) control mothers reported untreated hypertension. Selective β-blockers, centrally acting agents, renin-angiotensin system-acting agents, diuretics, and specific medications, methyldopa and atenolol, were not associated with hypospadias. Nonselective β-blockers (adjusted OR 3.22, 95% CI 1.47-7.05) were associated with hypospadias; however, P values adjusted for multiple testing were not statistically significant. We confirmed prior findings for associations between hypospadias and untreated hypertension (adjusted OR 2.09, 95% CI 1.76-2.48) and late initiation of treatment (adjusted OR 3.98, 95% CI 2.41-6.55). The increased risks would translate to severe hypospadias prevalences of 11.5, 17.7, and 21.9 per 10,000 births for women with untreated hypertension, nonselective β-blocker use, and late initiation of treatment, respectively. CONCLUSION Our study suggests a relationship between hypospadias and the severity of hypertension. LEVEL OF EVIDENCE II.

Abstract
PURPOSE The aim of this statement is to summarize data on stroke risk factors that are unique to and more common in women than men and to expand on the data provided in prior stroke guidelines and cardiovascular prevention guidelines for women. This guideline focuses on the risk factors unique to women, such as reproductive factors, and those that are more common in women, including migraine with aura, obesity, metabolic syndrome, and atrial fibrillation. METHODS Writing group members were nominated by the committee chair on the basis of their previous work in relevant topic areas and were approved by the American Heart Association (AHA) Stroke Council's Scientific Statement Oversight Committee and the AHA's Manuscript Oversight Committee. The panel reviewed relevant articles on adults using computerized searches of the medical literature through May 15, 2013. The evidence is organized within the context of the AHA framework and is classified according to the joint AHA/American College of Cardiology and supplementary AHA Stroke Council methods of classifying the level of certainty and the class and level of evidence. The document underwent extensive AHA internal peer review, Stroke Council Leadership review, and Scientific Statements Oversight Committee review before consideration and approval by the AHA Science Advisory and Coordinating Committee. RESULTS We provide current evidence, research gaps, and recommendations on risk of stroke related to preeclampsia, oral contraceptives, menopause, and hormone replacement, as well as those risk factors more common in women, such as obesity/metabolic syndrome, atrial fibrillation, and migraine with aura. CONCLUSIONS To more accurately reflect the risk of stroke in women across the lifespan, as well as the clear gaps in current risk scores, we believe a female-specific stroke risk score is warranted.

Abstract
Hypertension complicates 5% to 7% of all pregnancies. A subset of preeclampsia, characterized by new-onset hypertension, proteinuria, and multisystem involvement, is responsible for substantial maternal and fetal morbidity and is a marker for future cardiac and metabolic disease. This American Society of Hypertension (ASH) position paper summarizes the clinical spectrum of hypertension in pregnancy, focusing on preeclampsia. Recent research breakthroughs relating to etiology are briefly reviewed. Topics include classification of the different forms of hypertension during pregnancy, and status of the tests available to predict preeclampsia, and strategies to prevent preeclampsia and to manage this serious disease. The use of antihypertensive drugs in pregnancy, and the prevention and treatment of the convulsive phase of preeclampsia, eclampsia, with intravenous MgSO(4) is also highlighted. Of special note, this guideline article, specifically requested, reviewed, and accepted by ASH, includes solicited review advice from the American College of Obstetricians and Gynecologists.

Abstract
Hypertension in pregnancy is diagnosed on systolic blood pressure greater than or equal to 140 mm Hg and/or diastolic greater than or equal to 90 mm Hg. The classification systems separate chronic and gestational hypertension from preeclampsia. Significant uncertainty regarding optimal management is reflected in the differing major international society recommendations. Blood pressure treatment is designed to minimize maternal end-organ damage. Methyldopa, labetalol, hydralazine, and nifedipine are oral options; angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists are contraindicated. Women with preeclampsia should be closely monitored and receive intravenous magnesium sulfate.

Abstract
Acute myocardial infraction (AMI) in the obstetric patient is a rare event, although the incidence is rising due to advancing maternal age and pre-existing cardiac risk factors and medical co-morbidities. While atherosclerotic disease is the leading cause of AMI, coronary artery dissection is an important consideration in pregnancy and in the postpartum period. The physiological changes of pregnancy as well as pregnancy-specific risk factors can predispose the obstetric patient to AMI. Diagnosis of AMI can be challenging as symptoms may be atypical. Furthermore, diagnostic tests must be interpreted in the context of pregnancy. While the overall management of the obstetric patient with AMI is similar to that outside of pregnancy, drug therapy requires modification as some medications may be contraindicated in pregnancy and breastfeeding. There is limited information about prognosis and risk stratification but it is anticipated that future studies will address this issue.

Abstract
Nephrotic syndrome in a pregnant woman may be challenging, especially when the onset is early in pregnancy or with severe manifestations. Preeclampsia is the most common cause of nephrotic syndrome in pregnancy; however, this review will focus on the management of other renal causes. The aim of this pragmatic review is to address clinical issues that clinicians looking after women with nephrotic syndrome may encounter during pregnancy and the postpartum period. First, we discuss some general issues regarding nephrotic syndrome and its impact on maternal and fetal outcomes in pregnancy, and then we review the maternal management of nephrotic syndrome in pregnancy and during the postpartum period.
