Abstract
OBJECTIVE SARS-CoV-2 infection during pregnancy has been linked with an increased risk of hypertensive disorders of pregnancy (HDP). The aim of this study was to examine how both trimester and severity of SARS-CoV-2 infection impact HDP. METHODS We conducted a cohort study of SARS-CoV-2-infected individuals during pregnancy (n = 205) and examined the association between trimester and severity of infection with incidence of HDP using modified Poisson regression models to calculate risk ratios (RR) and 95% confidence intervals (CI). We stratified the analysis of trimester by severity to understand the role of timing of infection among those with similar symptomatology and also examined timing of infection as a continuous variable. RESULTS Compared to a reference cohort from 2018, SARS-CoV-2 infection did not largely increase the risk of HDP (RR: 1.17; CI:0.90, 1.51), but a non-statistically significant higher risk of preeclampsia was observed (RR: 1.33; CI:0.89, 1.98), in our small sample. Among the SARS-CoV-2 cohort, severity was linked with risk of HDP, with infections requiring hospitalization increasing the risk of HDP compared to asymptomatic/mild infections. Trimester of infection was not associated with risk of HDP, but a slight decline in the risk of HDP was observed with later gestational week of infection. Among patients with asymptomatic or mild symptoms, SARS-CoV-2 in the first trimester conferred a higher risk of HDP compared to the third trimester (RR: 1.70; CI:0.77, 3.77), although estimates were imprecise. CONCLUSION SARS-CoV-2 infection in early pregnancy may increase the risk of HDP compared to infection later in pregnancy.

Abstract
OBJECTIVE Preeclampsia, one of the most serious obstetric complications, is a heterogenous disorder resulting from different pathologic processes. However, placental oxidative stress and an anti-angiogenic state play a crucial role. Mitochondria are a major source of cellular reactive oxygen species. Abnormalities in mitochondrial structures, proteins, and functions have been observed in the placentae of patients with preeclampsia, thus mitochondrial dysfunction has been implicated in the mechanism of the disease. Mitochondrial nuclear retrograde regulator 1 (MNRR1) is a newly characterized bi-organellar protein with pleiotropic functions. In the mitochondria, this protein regulates cytochrome c oxidase activity and reactive oxygen species production, whereas in the nucleus, it regulates the transcription of a number of genes including response to tissue hypoxia and inflammatory signals. Since MNRR1 expression changes in response to hypoxia and to an inflammatory signal, MNRR1 could be a part of mitochondrial dysfunction and involved in the pathologic process of preeclampsia. This study aimed to determine whether the plasma MNRR1 concentration of women with preeclampsia differed from that of normal pregnant women. METHODS This retrospective case-control study included 97 women with preeclampsia, stratified by gestational age at delivery into early (<34 weeks, n = 40) and late (≥34 weeks, n = 57) preeclampsia and by the presence or absence of placental lesions consistent with maternal vascular malperfusion (MVM), the histologic counterpart of an anti-angiogenic state. Women with an uncomplicated pregnancy at various gestational ages who delivered at term served as controls (n = 80) and were further stratified into early (n = 25) and late (n = 55) controls according to gestational age at venipuncture. Maternal plasma MNRR1 concentrations were determined by an enzyme-linked immunosorbent assay. RESULTS 1) Women with preeclampsia at the time of diagnosis (either early or late disease) had a significantly higher median (interquartile range, IQR) plasma MNRR1 concentration than the controls [early preeclampsia: 1632 (924-2926) pg/mL vs. 630 (448-4002) pg/mL, p = .026, and late preeclampsia: 1833 (1441-5534) pg/mL vs. 910 (526-6178) pg/mL, p = .021]. Among women with early preeclampsia, those with MVM lesions in the placenta had the highest median (IQR) plasma MNRR1 concentration among the three groups [with MVM: 2066 (1070-3188) pg/mL vs. without MVM: 888 (812-1781) pg/mL, p = .03; and with MVM vs. control: 630 (448-4002) pg/mL, p = .04]. There was no significant difference in the median plasma MNRR1 concentration between women with early preeclampsia without MVM lesions and those with an uncomplicated pregnancy (p = .3). By contrast, women with late preeclampsia, regardless of MVM lesions, had a significantly higher median (IQR) plasma MNRR1 concentration than women in the control group [with MVM: 1609 (1392-3135) pg/mL vs. control: 910 (526-6178), p = .045; and without MVM: 2023 (1578-8936) pg/mL vs. control, p = .01]. CONCLUSIONS MNRR1, a mitochondrial regulator protein, is elevated in the maternal plasma of women with preeclampsia (both early and late) at the time of diagnosis. These findings may reflect some degree of mitochondrial dysfunction, intravascular inflammation, or other unknown pathologic processes that characterize this obstetrical syndrome.

Individual-Level and Community-Level Predictors of Healthy Pregnancy Outcomes in Multigravid Black Women. Obstet Gynecol 2024; 144:241-251. [PMID: 39024647 DOI: 10.1097/aog.0000000000005634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 04/04/2024] [Indexed: 06/09/2024]
Abstract
OBJECTIVE To identify individual- and community-level factors that predict the odds of multigravid Black women having consecutive pregnancies without adverse pregnancy outcomes. METHODS We conducted a secondary analysis of 515 multigravid Black women from a longitudinal observational study (2017-2019). We assessed the presence of adverse pregnancy outcomes (hypertensive disorders, gestational diabetes, preterm birth, fetal growth restriction, placental abruption, and pregnancy loss) for the index and prior pregnancies. We examined U.S. Census data, medical records, and surveys across multiple socioecologic domains: personal, behavioral, socioeconomic, and policy. We estimated adjusted odds ratios (aORs) and 95% CIs for the association between individual- and community-level factors and consecutive healthy pregnancies using hierarchical logistic regression models adjusted for maternal age, body mass index (BMI), gravidity, interpregnancy interval, and median household income. RESULTS Among 515 multigravid Black women (age 27±5 years, BMI 31.4±8.9, gravidity 4±2), 38.4% had consecutive healthy pregnancies without adverse pregnancy outcomes. Individual-level factors associated with consecutive healthy pregnancies included normal glucose tolerance (aOR 3.9, 95% CI, 1.2-12.1); employment (aOR 1.9, 95% CI, 1.2-2.9); living in communities with favorable health indicators for diabetes, hypertension, and physical activity; and household income of $50,000 per year or more (aOR 3.5, 95% CI, 1.4-8.7). When individual and community factors were modeled together, only income and employment at the individual and community levels remained significant. CONCLUSION Individual and community income and employment are associated with consecutive healthy pregnancies in a cohort of Black patients, emphasizing the need for comprehensive, multilevel systems interventions to reduce adverse pregnancy outcomes for Black women.

Abstract
OBJECTIVE The influence of hypertensive disorders of pregnancy (HDP) on left atrial (LA) mechanics assessed by speckle tracking echocardiography (STE) has been poorly investigated. Accordingly, we performed a meta-analysis to summarize the main findings of STE studies who measured LA reservoir (LASr), conduit (LAScd) and contractile (LASct) strain in HDP women. STUDY DESIGN All echocardiographic studies assessing LA strain parameters in HDP women vs. healthy controls, selected from PubMed and EMBASE databases, were included. The risk of bias was assessed by using the National Institutes of Health (NIH) Quality Assessment of Case-Control Studies. Continuous data (LASr, LAScd and LASct) were pooled as standardized mean difference (SMD) comparing HDP group with healthy controls. The overall SMDs of LASr, LAScd and LASct were calculated using the random-effect model. RESULTS The full-texts of 8 studies with 566 HDP women and 420 healthy pregnant women were analyzed. Average LASr (34.3 ± 6.4 vs 42.7 ± 5.3 %, P = 0.01) and LAScd (23.4 ± 6.3 vs 32.5 ± 6.0 %, P < 0.001) were significantly lower in HDP women than controls, whereas LASct (-13.0 ± 5.4 vs -13.7 ± 4.5 %, P = 0.18) was similar in the two groups of women. Substantial heterogeneity was detected among the studies evaluating LASr (I2 = 94.3 %), LAScd (I2 = 64.9 %) and LASct (I2 = 86.4 %). SMDs were large and statistically significant for LASr (-1.70, 95 %CI -2.34,-1.06, P < 0.001) and LAScd (-1.35, 95 %CI -1.69,-1.00, P < 0.001), small and not statistically significant for LASct (-0.11, 95 %CI -0.60,0.39, P = 0.678) assessment. Egger's test gave P-values of 0.10, 0.34 and 0.75 for LASr, LAScd and LASct measurement respectively, indicating no publication bias. On meta-regression analysis, none of the moderators was significantly associated with effect modification for LASr and its components (all P < 0.05). CONCLUSIONS HDPs are independently associated with LASr impairment in pregnancy. STE allows to identify, among HDP women, those who might benefit from a more aggressive antihypertensive treatment and/or a closer clinical follow-up, aimed at reducing the risk of adverse maternal outcome and cardiovascular complications later in life.

Abstract
BACKGROUND Although smoking cigarettes has been shown to have a protective effect on preeclampsia, quitting smoking also results in weight gain. Weight gain leading to an obese body mass index is a risk factor for hypertensive disorders of pregnancy (HDP). METHODS The objective of this study was to explore the relationship between smoking status, body mass index, and gestational weight gain on the risk of HDP. A cross-sectional analysis was performed utilizing US birth certificate data. We examined HDP risks in relation to maternal smoking, body mass index, and gestational weight gain. Associations were expressed as rate ratios with 95% CIs and adjusted for potential confounders. Clinically important outcomes of smoking throughout pregnancy were also evaluated. RESULTS Of the 22 191 568 women studied, HDP rates among nonsmokers, those who quit smoking, and persistent smokers were 6.8%, 8.6%, and 7.0%, respectively. The rate ratio of HDP was higher for women who quit smoking, especially evident among those with excessive gestational weight gain. Corrections for exposure misclassification and unmeasured confounding strengthened the associations among women who quit smoking. There was an almost 6-fold increase in the rate of stillbirth for persistent smokers (2.3%) compared with those who quit smoking (0.4%) and nonsmokers (0.4%). CONCLUSIONS Women who quit smoking during pregnancy were more likely to gain excessive weight and develop HDP. Although quitting smoking during pregnancy may be associated with an increase in the risk of HDP, it is also associated with a reduced risk of stillbirth. Pregnant women counseled to quit smoking should also receive counseling on nutrition and exercise to prevent excessive gestational weight gain.

Abstract
OBJECTIVES To assess clinical utility of the urine Congo red dot test (CRDT) in predicting composite adverse maternal and neonatal outcomes in women with suspected preeclampsia (PE). METHODS CRDT result and pregnancy outcomes were prospectively documented in women with new onset or pre-existing hypertension, new or pre-existing proteinuria, PE symptoms and suspected PE-related fetal growth restriction or abnormal Doppler presenting from 20 weeks' gestation between January 2020 and December 2022. Participants and clinicians were blinded to the CRDT result and managed according to internally agreed protocols. Composite maternal outcome was defined as PE, postpartum hemorrhage, intensive care unit admission, and maternal death. Composite neonatal outcome was defined as small for gestational age, preterm birth, 5-min Apgar score < 7, neonatal intensive care unit admission, and neonatal death. RESULTS Two hundred and forty-four women out of two hundred and fifty-one (97.2%) had a negative CRDT. All seven women with positive CRDT had both adverse maternal and neonatal outcomes, giving positive predictive values (PPV) of 100%. Rates of composite adverse maternal and neonatal outcomes in CDRT negative women were 103/244 [42.2%, 95% confidence interval (CI) 36.2%-48.5%] and 170/244 (69.7%, 95% CI 63.6%-75.1%), respectively. CRDT negative predictive values (NPV) for adverse maternal and neonatal outcomes were, respectively, 141/244 (57.8%, 95% CI 48.6%-68.2%) and 74/244 (30.3%, 95% CI 23.8%-38.1%). CONCLUSION CRDT had low NPV but high PPV for adverse maternal and neonatal outcomes in women with suspected PE. Its role in clinical management and triage of women with suspected PE is limited as it cannot identify those at low risk of developing adverse outcomes.

Abstract
BACKGROUND In high-resource settings, biomarkers of angiogenic balance, such as the soluble fms-like tyrosine kinase-1 (sFlt1)/placental growth factor (PlGF) ratio, have been studied extensively to aid in evaluation of patients with suspected preeclampsia (PE), and have been incorporated into the 2021 International Society for the Study of Hypertension in Pregnancy definition of PE. The utility in under-resourced settings has not been as well characterized. OBJECTIVE This analysis sought to identify the role of the sFlt1/PlGF ratio in the evaluation of patients with or without hypertension who are suspected of having PE without other diagnostic information. STUDY DESIGN This is a secondary analysis of a prior prospective study of patients who were presented with suspected PE at ≥20+0 weeks' gestation at a single academic tertiary care center. Patients were recruited in the parent study from July 2009 to June 2012. In the original study, clinicians were masked to biomarker results, and patients were followed by chart review. In this analysis, the performance of the sFlt1/PlGF ratio (≤38, >38, or >85) was assessed alone in identifying both hypertensive and non-hypertensive patients at risk of evolving into PE with severe features (PE-SF; American College of Obstetricians and Gynecologists' definition) within two weeks of the triage visit (PE-SF2). Hypertension was defined as a blood pressure (BP)≥140/90 mmHg. RESULTS There were 1043 patients included in the analysis; of whom, 579 (55.5%) and 464 (44.5%) presented with or without hypertension, respectively. In triage, 332 (75.4%) of hypertensive patients presented due to BP concerns, and the remainder were evaluated due to other features (new-onset headache, proteinuria, or edema). On triage evaluation, 66.8% of all patients had a normal sFlt1/PlGF ratio ≤38, and 17.0% had an elevated ratio >85. Among hypertensive patients, a sFlt1/PlGF ratio ≤38 was a good rule-out test for PE-SF2 (negative likelihood ratio [LR-] of 0.15), and a ratio >85 was a good rule-in test (positive likelihood ratio [LR+] of 5.75). Among normotensive patients, sFlt1/PlGF was useful as a rule-in test for ratio >38 (LR+ 5.13) and >85 (LR+ 12.80). Stratified by gestational age, sFlt1/PlGF continued to be a good rule in and good rule out test at <35 weeks among those with hypertension but did not have good test performance ≥35 weeks. sFlt1/PlGF had a good test performance as a rule in test for >85 regardless of gestational age. In triage, 4.3% (30/693) of patients with sFlt1/PlGF ratio <38 had concurrent laboratory evidence of PE, compared with 15.9% (28/176) patients with ratio >85. CONCLUSION These findings support the potential for the use of sFlt1/PlGF and BP measurement alone in resource-limited settings where other laboratory tests or clinical expertise are unavailable for risk stratification. Performance of the biomarker varied by the presence of hypertension and gestational age.

Abstract
Over the past 3 decades, a substantial body of high-quality evidence has guided the diagnosis and management of elevated blood pressure (BP) in the outpatient setting. In contrast, there is a lack of comparable evidence for guiding the management of elevated BP in the acute care setting, resulting in significant practice variation. Throughout this scientific statement, we use the terms acute care and inpatient to refer to care received in the emergency department and after admission to the hospital. Elevated inpatient BP is common and can manifest either as asymptomatic or with signs of new or worsening target-organ damage, a condition referred to as hypertensive emergency. Hypertensive emergency involves acute target-organ damage and should be treated swiftly, usually with intravenous antihypertensive medications, in a closely monitored setting. However, the risk-benefit ratio of initiating or intensifying antihypertensive medications for asymptomatic elevated inpatient BP is less clear. Despite this ambiguity, clinicians prescribe oral or intravenous antihypertensive medications in approximately one-third of cases of asymptomatic elevated inpatient BP. Recent observational studies have suggested potential harms associated with treating asymptomatic elevated inpatient BP, which brings current practice into question. Despite the ubiquity of elevated inpatient BPs, few position papers, guidelines, or consensus statements have focused on improving BP management in the acute care setting. Therefore, this scientific statement aims to synthesize the available evidence, provide suggestions for best practice based on the available evidence, identify evidence-based gaps in managing elevated inpatient BP (asymptomatic and hypertensive emergency), and highlight areas requiring further research.

Abstract
OBJECTIVES To evaluate associations between serum analytes used for genetic screening and obstetric complications among twin pregnancies. METHODS This cohort included twins delivered at a tertiary care hospital from 2009 to 2017. Abnormal levels of pregnancy associated plasma protein (PAPP-A), first and second trimester human chorionic gonadotropin (hCG), alpha fetoprotein (AFP), estriol, and inhibin, reported as multiples of the median (MoM), were defined as <5 %ile or >95 %ile for our cohort. Associations between abnormal analytes and preterm delivery, small for gestational age, and pregnancy-associated hypertension were calculated using Fisher's exact test. RESULTS A total of 357 dichorionic/diamniotic and 123 monochorionic/diamniotic twins were included. Among dichorionic/diamniotic twins, elevated AFP (>3.70 MoM) was associated with increased preterm delivery <34 weeks (44.4 vs. 16.5 %, p=0.007), while elevated inhibin (>4.95 MoM) was associated with increased preterm delivery<37 weeks (94.1 vs. 58.8 %, p=0.004). For monochorionic/diamniotic twins, elevated inhibin (>6.34 MoM) was associated increased preterm delivery <34 weeks (66.7 vs. 24.8 %, p=0.04) and hypertension (66.7 vs. 21.4 %, p=0.03). CONCLUSIONS Selected abnormal analyte levels were associated with increased rates of adverse outcomes in twin pregnancies, which differed by chorionicity. Our findings assist providers in interpreting abnormal analyte levels in twin pregnancies and may help to identify those at increased risk for adverse outcomes.

Trophoblast Side-Population Markers are Dysregulated in Preeclampsia and Fetal Growth Restriction. Stem Cell Rev Rep 2024:10.1007/s12015-024-10764-w.

Abstract
Dysregulated progenitor cell populations may contribute to poor placental development and placental insufficiency pathogenesis. Side-population cells possess progenitor properties. Recent human trophoblast side-population isolation identified enrichment of 8 specific genes (CXCL8, ELL2, GATA6, HK2, HLA-DPB1, INTS6, SERPINE3 and UPP1) (Gamage et al. 2020, Stem Cell Rev Rep). We characterised these trophoblast side-population markers in human placenta and in placental insufficiency disorders: preeclampsia and fetal growth restriction (FGR). Trophoblast side-population markers localised to mononuclear trophoblasts lining the placental villous basement membrane in preterm control, preeclamptic and FGR placental sections (n = 3, panel of 3 markers/serial section). Analysis of single-cell transcriptomics of an organoid human trophoblast stem cell (hTSC) to extravillous trophoblast (EVT) differentiation model (Shannon et al. 2022, Development) identified that all side-population genes were enriched in mononuclear trophoblast and trophoblasts committed to differentiation under hTSC culture conditions. In vitro validation via 96 h time course hTSC differentiation to EVTs or syncytiotrophoblasts (n = 5) demonstrated ELL2 and HK2 increased with differentiation (p < 0.0024, p < 0.0039 respectively). CXCL8 and HLA-DPB1 were downregulated (p < 0.030, p < 0.011 respectively). GATA6 and INTS6 increased with EVT differentiation only, and UPP1 reduced with syncytialisation. SERPINE3 was undetectable. Trophoblast side-population marker mRNA was measured in human placentas (< 34-weeks' gestation; n = 78 preeclampsia, n = 30 FGR, and n = 18 gestation-matched controls). ELL2, HK2 and CXCL8 were elevated in preeclamptic (p = 0.0006, p < 0.0001, p = 0.0335 respectively) and FGR placentas (p = 0.0065, p < 0.0001, p = 0.0001 respectively) versus controls. Placental GATA6 was reduced in pregnancies with preeclampsia and FGR (p = 0.0014, p = 0.0146 respectively). Placental INTS6 was reduced with FGR only (p < 0.0001). This study identified the localisation of a unique trophoblast subset enriched for side-population markers. Aberrant expression of some side-population markers may indicate disruptions to unique trophoblast subtypes in placental insufficiency.

Corticosteroids for improving patient-relevant outcomes in HELLP syndrome: a systematic review and meta-analysis. BMC Pregnancy Childbirth 2024; 24:487. [PMID: 39026148 DOI: 10.1186/s12884-024-06665-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Accepted: 06/28/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND We conducted this updated systematic review to assess the effects of corticosteroids vs. placebo or no treatment for improving patient-relevant outcomes in hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome. METHODS CENTRAL, MEDLINE/PubMed, Web of Science, and Scopus, from the date of inception of the databases to February 3, 2024 were searched. Reference lists of included studies and systematic reviews were thoroughly searched. We included RCTs that enrolled women with HELLP syndrome, whether antepartum or postpartum, to receive any corticosteroid versus placebo or no treatment. No language or publication date restrictions were made. We used a dual independent approach for screening titles and abstracts, full text screening, and data extraction. Risk of bias was assessed in the included studies using Cochrane's RoB 2 tool. Pairwise meta-analyses were conducted, where two or more studies met methodological criteria for inclusion. GRADE approach was used to assess certainty of evidence for the pre-specified outcomes. RESULTS Fifteen trials (821 women) compared corticosteroids with placebo or no treatment. The effect of corticosteroids is uncertain for the primary outcome i.e., maternal death (risk ratio [RR] 0.77, 95% confidence interval [CI] 0.25 to 2.38, very low certainty evidence). Out of 6 studies reporting maternal death, 5 were judged overall to have "low risk" of bias. The effect of corticosteroids is also uncertain for other important outcomes including pulmonary edema (RR 0.70, 95% CI 0.23 to 2.09), dialysis (RR 3, 95% CI 0.13 to 70.78), liver morbidity (hematoma, rupture, and failure; RR 0.22, 95% CI 0.03 to 1.83), or perinatal death (0.64, 95% CI 0.21 to 1.97) because of very low certainty evidence. Low certainty evidence suggests that corticosteroids have little or no effect on the need for platelet transfusion (RR 0.98, 95% CI 0.60 to 1.60) and may result in a slight reduction in acute renal failure (RR 0.67, 95% CI 0.40 to 1.12). Subgroup and sensitivity analyses showed results that were similar to the primary synthesis. CONCLUSIONS In women with HELLP syndrome, the effect of corticosteroids vs. placebo or no treatment is uncertain for patient-relevant outcomes including maternal death, maternal morbidity, and perinatal death. These uncertainties regarding this critical question should be addressed by adequately powered rigorous trials. SYSTEMATIC REVIEW REGISTRATION Center for Open Science, osf.io/yzku5.

Abstract
OBJECTIVE To investigate the optimal gestational age to deliver pregnant people with chronic hypertension to improve perinatal outcomes. METHODS We conducted a planned secondary analysis of a randomized controlled trial of chronic hypertension treatment to different blood pressure goals. Participants with term, singleton gestations were included. Those with fetal anomalies and those with a diagnosis of preeclampsia before 37 weeks of gestation were excluded. The primary maternal composite outcome included death, serious morbidity (heart failure, stroke, encephalopathy, myocardial infarction, pulmonary edema, intensive care unit admission, intubation, renal failure), preeclampsia with severe features, hemorrhage requiring blood transfusion, or abruption. The primary neonatal outcome included fetal or neonatal death, respiratory support beyond oxygen mask, Apgar score less than 3 at 5 minutes, neonatal seizures, or suspected sepsis. Secondary outcomes included intrapartum cesarean birth, length of stay, neonatal intensive care unit admission, respiratory distress syndrome (RDS), transient tachypnea of the newborn, and hypoglycemia. Those with a planned delivery were compared with those expectantly managed at each gestational week. Adjusted odds ratios (aORs) with 95% CIs are reported. RESULTS We included 1,417 participants with mild chronic hypertension; 305 (21.5%) with a new diagnosis in pregnancy and 1,112 (78.5%) with known preexisting hypertension. Groups differed by body mass index (BMI) and preexisting diabetes. In adjusted models, there was no association between planned delivery and the primary maternal or neonatal composite outcome in any gestational age week compared with expectant management. Planned delivery at 37 weeks of gestation was associated with RDS (7.9% vs 3.0%, aOR 2.70, 95% CI, 1.40-5.22), and planned delivery at 37 and 38 weeks was associated with neonatal hypoglycemia (19.4% vs 10.7%, aOR 1.97, 95% CI, 1.27-3.08 in week 37; 14.4% vs 7.7%, aOR 1.82, 95% CI, 1.06-3.10 in week 38). CONCLUSION Planned delivery in the early-term period compared with expectant management was not associated with a reduction in adverse maternal outcomes. However, it was associated with increased odds of some neonatal complications. Delivery timing for individuals with mild chronic hypertension should weigh maternal and neonatal outcomes in each gestational week but may be optimized by delivery at 39 weeks.

Abstract
BACKGROUND We evaluated how elevated blood pressure in children exposed to preeclampsia (PE) impacted on their cardiac structure and function, as well as relations with maternal, gestational, and perinatal factors and child body size and composition. METHODS AND RESULTS A total of 182 PE (46 early-onset preeclampsia) and 85 unexposed (non-PE) children were examined in the FINNCARE study 8 to 12 years after the index pregnancy with echocardiography; office, central, and 24-hour ambulatory blood pressures; and body anthropometrics and composition. PE children had lower right ventricular basal sphericity index (mean difference, -0.26 95% CI, -0.39 to -0.12) and lower mitral lateral E'-wave peak velocity (-1.4 cm/s [95% CI, -2.1 to -0.6]), as well as higher E to E' ratio (0.40 [95% CI, 0.15-0.65]) and indexed tricuspid annular plane systolic excursion (0.03 [95% CI, 0.01-0.05]) compared with non-PE children. These differences were accentuated in early-onset PE children. Left ventricular mass (LVM) or left atrial volume were not different between PE and non-PE children. Lean body mass, body fat percentage, and 24-hour systolic blood pressure were independent predictors of LVM. Lean body mass and body fat percentage were independent predictors of left atrial volume. No significant associations between LVM or left atrial volume and maternal, gestational, or perinatal parameters were found. CONCLUSIONS Preadolescent PE children display a more globular-shaped right ventricle with higher longitudinal systolic displacement as well as mildly altered diastolic indices, with the alterations being pronounced in early-onset preeclampsia. Lean body mass and adiposity are independently related with LVM and left atrial volume, and systolic blood pressure with LVM in both PE and non-PE children. These unfavorable associations indicate remodeling of cardiac structure in young children also reflected in mild functional changes in PE children.

Abstract
PURPOSE While cell-free DNA (cfDNA) screening has emerged as a screening modality for common aneuploidies, further research and several publications over the past decade suggested some correlation between the low concentrations of cfDNA and a number of pregnancy-related complications. The primary goal of this systematic review and meta-analysis was to assess the potential value of low-ff levels in the prediction of subsequent PE/PIH, GDM, SGA/FGR, and PTB. The meta-analysis results aim at summarizing the currently available literature data and determining the clinical relevance of this biochemical marker and the potential necessity for additional investigation of its utility in complications other than the detection of common aneuploidies. METHODS This systematic review and meta-analysis was designed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. It included all observational studies that reported low -ff levels after the performance of non-invasive prenatal testing (NIPT) as part of the screening for chromosomal abnormalities and their association with adverse pregnancy outcomes, namely the subsequent development of hypertensive disorders of pregnancy, gestational diabetes, preterm birth, and the detection of small for gestational age fetuses or growth-restricted fetuses. The Medline (1966-2041), Scopus (2004-2024), Clinicaltrials.gov (2008-2024), EMBASE (1980-2024), Cochrane Central Register of Controlled Trials CENTRAL (1999-2024) and Google Scholar (2004-2024) databases were used in our primary search along with the reference lists of electronically retrieved full-text papers. The date of our last search was set at February 29, 2024. RESULTS Our search identified 128 potentially relevant studies and,overall, 8 studies were included in the present systematic review that enrolled a total of 72,507 patients. Low ff of cfDNA cfDNA was positively associated with HDP (OR 1.66, 95% CI 1.34, 2.06, I-square test: 56%). Low ff of cfDNA was positively associated with GDM (OR 1.27, 95% CI 1.03, 1.56, I-square test: 76%). Furthermore, low ff levels were positively associated with SGA/FGR (OR 1.63, 95% CI 1.32, 2.03, I-square test: 0%). Low ff levels were positively correlated with the risk for PTB but the association did not manage to reach a statistical significant level (OR 1.22, 95% CI 0.89, 1.67, I-square test: 66%). CONCLUSION Our study suggests that low ff is associated with increased risk of adverse perinatal outcomes, including PE/PIH, GDM, and SGA/FGR. However, the relationship between ff and PTB remains unclear due to conflicting evidence. It should be emphasized that further research is needed to reveal the underlying mechanisms behind the association of low ff with adverse pregnancy outcomes and explore its potential role in an overall prenatal screening, which could potentially not be limited to detecting aneuploidies.

Abstract
OBJECTIVE To evaluate whether continuous glucose monitoring (CGM)-derived glycemic patterns observed throughout pregnancy were associated with adverse perinatal outcomes, specifically fetal growth disorders and hypertensive disorders of pregnancy (HDP). METHODS We conducted a prospective observational study of individuals with viable singleton pregnancies and screening hemoglobin A1c levels less than 6.5%. Those with preexisting diabetes were excluded. Enrollment occurred at the earliest gestational age before 17 weeks. Participants wore blinded continuous glucose monitors consecutively as willing until delivery. Those with at least 14 days of CGM data were included in analysis. Rates of large-for-gestational-age (LGA) neonates, small-for-gestational age (SGA) neonates, and HDP were assessed. Continuous glucose monitoring-derived glycemic metrics were calculated, including mean glucose level and percent time above and below thresholds. Two-sample t tests were used to compare glycemic metrics between participants with and without adverse perinatal outcomes. RESULTS Of 937 participants enrolled, 760 met inclusion criteria. Those delivering LGA neonates or who were diagnosed with HDP had higher mean glucose levels (102±9 vs 100±8, P=.01 and 103±8 vs 99±8, P<.001) and spent more time above 120 mg/dL (median 16% vs 12%, P=.006, and 16% vs 12%, P<.001, respectively) and above 140 mg/dL (median 3.9% vs 2.8%, P=.006, and 3.5% vs 2.8%, P<.001, respectively) throughout gestation than those without these outcomes. These findings were present regardless of gestational diabetes mellitus status. Participants with SGA neonates had lower mean glucose levels (97±7 vs 101±8, P=.01) and spent less time above 140 mg/dL (median 1.6% vs 2.3%, P=.01) and more time below 63 mg/dL (median 3.0% vs 2.3%, P=.02) than those without SGA neonates. CONCLUSION Individuals with LGA neonates or HDP exhibit a slightly higher mean glucose levels and spend more time hyperglycemic in early pregnancy than those who do not experience these outcomes.

Abstract
Maternal morbidity and mortality remain significant challenges in the United States, with substantial burden during the postpartum period. The Centers for Disease Control and Prevention, in partnership with the National Association of Community Health Centers, began an initiative to build capacity in Federally Qualified Health Centers to (1) improve the infrastructure for perinatal care measures and (2) use perinatal care measures to identify and address gaps in postpartum care. Two partner health center-controlled networks implemented strategies to integrate evidence-based recommendations into the clinic workflow and used data-driven health information technology (HIT) systems to improve data standardization for quality improvement of postpartum care services. Ten measures were created to capture recommended care and services. To support measure capture, a data cleaning algorithm was created to prioritize defining pregnancy episodes and delivery dates and address data inconsistencies. Quality improvement activities targeted postpartum care delivery tailored to patients and care teams. Data limitations, including inconsistencies in electronic health record documentation and data extraction practices, underscored the complexity of integrating HIT solutions into postpartum care workflows. Despite challenges, the project demonstrated continuous quality improvement to support data quality for perinatal care measures. Future solutions emphasize the need for standardized data elements, collaborative care team engagement, and iterative HIT implementation strategies to enhance perinatal care quality. Our findings highlight the potential of HIT-driven interventions to improve postpartum care within health centers, with a focus on the importance of addressing data interoperability and documentation challenges to optimize and monitor initiatives to improve postpartum health outcomes.

Abstract
OBJECTIVE Survival analysis is widely utilized in healthcare to predict the timing of disease onset. Traditional methods of survival analysis are usually based on Cox Proportional Hazards model and assume proportional risk for all subjects. However, this assumption is rarely true for most diseases, as the underlying factors have complex, non-linear, and time-varying relationships. This concern is especially relevant for pregnancy, where the risk for pregnancy-related complications, such as preeclampsia, varies across gestation. Recently, deep learning survival models have shown promise in addressing the limitations of classical models, as the novel models allow for non-proportional risk handling, capturing nonlinear relationships, and navigating complex temporal dynamics. METHODS We present a methodology to model the temporal risk of preeclampsia during pregnancy and investigate the associated clinical risk factors. We utilized a retrospective dataset including 66,425 pregnant individuals who delivered in two tertiary care centers from 2015 to 2023. We modeled the preeclampsia risk by modifying DeepHit, a deep survival model, which leverages neural network architecture to capture time-varying relationships between covariates in pregnancy. We applied time series k-means clustering to DeepHit's normalized output and investigated interpretability using Shapley values. RESULTS We demonstrate that DeepHit can effectively handle high-dimensional data and evolving risk hazards over time with performance similar to the Cox Proportional Hazards model, achieving an area under the curve (AUC) of 0.78 for both models. The deep survival model outperformed traditional methodology by identifying time-varied risk trajectories for preeclampsia, providing insights for early and individualized intervention. K-means clustering resulted in patients delineating into low-risk, early-onset, and late-onset preeclampsia groups-notably, each of those has distinct risk factors. CONCLUSION This work demonstrates a novel application of deep survival analysis in time-varying prediction of preeclampsia risk. Our results highlight the advantage of deep survival models compared to Cox Proportional Hazards models in providing personalized risk trajectory and demonstrating the potential of deep survival models to generate interpretable and meaningful clinical applications in medicine.

Abstract
The prevalence of overweight and obese people worldwide has dramatically increased in the last decades and is yet to peak. At the same time and partly due to obesity and associated assisted reproduction, twinning rates showed a clear rise in the last years. Adverse fetomaternal outcomes are known to occur in singleton and twin pregnancies in overweight and obese women. However, the impact of the obesity levels as defined by the World Health Organization on the outcomes of twin pregnancies has not been thoroughly studied. Therefore, the purpose of this study is to examine how maternal overweight, and the level of obesity affect fetomaternal outcomes in twin pregnancies, hypothesizing a higher likelihood for adverse outcomes with overweight and each obesity level. This is a retrospective cohort study with 2,349 twin pregnancies that delivered at the Buergerhospital Frankfurt, Germany between 2005 and 2020. The mothers were divided into exposure groups depending on their pre-gestational body mass index; these were normal weight (reference group), overweight and obesity levels I, II, and III. A multivariate logistic regression analysis was performed to assess the influence of overweight and obesity on gestational diabetes mellitus, preeclampsia, postpartum hemorrhage, intrauterine fetal death, and a five-minutes Apgar score below seven. The adjusted odds ratio for gestational diabetes compared to normal weight mothers were 1.47, 2.79, 4.05, and 6.40 for overweight and obesity levels I, II and III respectively (p = 0.015 for overweight and p < 0.001 for each obesity level). Maternal BMI had a significant association with the risk of preeclampsia (OR 1.04, p = 0.028). Overweight and obesity did not affect the odds of postpartum hemorrhage, fetal demise, or a low Apgar score. While maternal overweight and obesity did not influence the fetal outcomes in twin pregnancies, they significantly increased the risk of gestational diabetes and preeclampsia, and that risk is incremental with increasing level of obesity.

Abstract
Gestational hypertension (PIH), especially pre-eclampsia (PE), is a common complication of pregnancy. This condition poses significant risks to the health of both the mother and the fetus. Emerging evidence suggests that epigenetic modifications, particularly DNA methylation, may play a role in initiating the earliest pathophysiology of PIH. This article describes the relationship between DNA methylation and placental trophoblast function, genes associated with the placental microenvironment, the placental vascular system, and maternal blood and vascular function, abnormalities of umbilical cord blood and vascular function in the onset and progression of PIH, as well as changes in DNA methylation in the progeny of PIH, in terms of maternal, fetal, and offspring. We also explore the latest research on DNA methylation-based early detection, diagnosis and potential therapeutic strategies for PIH. This will enable the field of DNA methylation research to continue to enhance our understanding of the epigenetic regulation of PIH genes and identify potential therapeutic targets.

Abstract
Hyponatremia, though common in women with preeclampsia, has not been well studied. Our primary objectives are to assess the clinical characteristics and emergency therapy applied to subjects diagnosed with preeclampsia. We hypothesize that hyponatremia present in preeclamptic patients with severe features is associated with greater use of emergency hypertensives, antenatal steroids, and cesarean delivery. This is a retrospective descriptive study utilizing an electronic health record database (TriNetX ®). We collected and evaluated the following data of subjects aged 15 to 54 years with preeclampsia with severe features diagnosis: demographics, diagnostic codes, medication codes, procedure codes, deaths, and laboratory results. A total of 2,901 subjects [215 (7.4%)] with a sodium level below 134 mEq/L and [2686 (92.6%)] with a sodium level above 135 mEq/L were included. A higher proportion of subjects in the below 134 sodium group received emergency antihypertensives [165 (76.7%) versus 1811 (67.4%), p = 0.01], antenatal steroids [103 (47.9%) versus 953 (35.5%), p = 0.001], and cesarean section [27 (12.6%) versus 97 (3.6%), p = <0.001]. We found that hyponatremia may be associated with emergency antihypertensive use, antenatal steroid use, and cesarean section in patients with preeclampsia with severe features. Future research is needed to determine if routine sodium levels assessed in preeclamptic subjects with severe features identify subjects at risk of receiving these treatments.

Abstract
Preeclampsia is characterized by impaired angiogenesis and assessment of angiogenic factors can play a crucial role in the early diagnosis of preeclampsia. The current study reports the levels of angiogenic factors longitudinally from early pregnancy in women with preeclampsia and in the subtypes of preeclampsia, to identify their role in early prediction of preeclampsia. A total of 1154 women with singleton pregnancies were recruited in early pregnancy from 2 hospitals. Blood samples were collected, plasma samples were separated and stored at four time points across gestation: V1 = 11-14 weeks, V2 = 18-22 weeks, V3 = 26-28 weeks, and V4 = at delivery. The current study includes a total of 108 women developed preeclampsia (PE), and 216 matched controls. Angiogenic factors were estimated using commercially available ELISA kits. Receiver operating characteristic (ROC) curves were used to evaluate the potential diagnostic value in the prediction of PE. Lower levels of VEGF, PlGF, and higher levels of sEng and sEng/PlGF ratio (p < 0.05 for all) predate clinical diagnosis in women with preeclampsia. sEng levels and sEng/PlGF ratio showed significant correlation with odds of preeclampsia at all the timepoints. This study identifies a cut off of 33.5 for sFlt-1/PlGF and 25.9 for sEng/PlGF for prediction of early onset preeclampsia. This study reports various angiogenic factors serially across gestation in a general population to identify women at risk of developing preeclampsia and its subtypes. The study also reports a potential biomarker and a pragmatic window for estimation of angiogenic markers to identify women at risk.

Abstract
This study utilized Mendelian randomization to explore the impact of hypertensive disorders of pregnancy and their subtypes on brain structures, using genome-wide association study data from the FinnGen consortium for hypertensive disorders of pregnancy exposure and brain structure data from the ENIGMA consortium as outcomes. The inverse-variance weighted method, along with Cochran's Q test, Mendelian randomization-Egger regression, Mendelian randomization-PRESSO global test, and the leave-one-out approach, were applied to infer causality and assess heterogeneity and pleiotropy. Findings indicate hypertensive disorders of pregnancy are associated with structural brain alterations, including reduced cortical thickness in areas like the insula, isthmus cingulate gyrus, superior temporal gyrus, temporal pole, and transverse temporal gyrus, and an increased surface area in the superior frontal gyrus. Specific associations were found for hypertensive disorders of pregnancy subtypes: chronic hypertension with superimposed preeclampsia increased cortical thickness in the supramarginal gyrus; preeclampsia/eclampsia led to thinner cortex in the lingual gyrus and larger hippocampal volume and superior parietal lobule surface area. Chronic hypertension was associated with reduced cortical thickness in the caudal and rostral anterior cingulate and increased surface area of the cuneus and thickness of the pars orbitalis cortex. Gestational hypertension showed no significant brain region changes. These insights clarify hypertensive disorders of pregnancies' neurological and cognitive effects by identifying affected brain regions.

The sFlt-1/PlGF-ratio and the risk of preeclampsia-related adverse outcomes in subsequent pregnancies with signs and symptoms of a preeclampsia. Pregnancy Hypertens 2024; 37:101140. [PMID: 38964026 DOI: 10.1016/j.preghy.2024.101140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 05/14/2024] [Accepted: 06/26/2024] [Indexed: 07/06/2024]
Abstract
OBJECTIVES This study characterizes the outcome of two subsequent pregnancies with suspected preeclampsia (PE). We investigated the diagnostic accuracy of clinical signs, Doppler examinations, and the soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF)-ratio to predict PE-related adverse outcomes (AO). The sFlt-1/PlGF-ratio of the first pregnancy was compared to the outcome of the subsequent pregnancy. STUDY DESIGN A total of 1928 patients at risk for preeclampsia were screened, of them 1117 were eligible for inclusion. Of these, 84 women presented with suspected PE in two subsequent pregnancies. OUTCOME MEASURES Diagnostic accuracy of clinical markers was assessed. Associations between the sFlt-1/PlGF-ratio in the first and the odds of an AO in the subsequent pregnancy were investigated with logistic regression. RESULTS The prevalence of AOs decreased from 27.4 % in the first to 17.9 % in the second pregnancy. Comparison of the accuracy of the different clinical markers for an AO showed a high specificity for an sFlt-1/PlGF-ratio at the cut-off of ≥ 85 in both pregnancies (81.3 %, 95 % CI 63.6-92.8 vs 92.6 %,95 % CI 83.7-97.6), but a lower sensitivity in the second pregnancy (92.9 %, 95 % CI 66.1-99.8 vs 33.3%, 95 % CI 11.8-61.6). An elevated sFlt-1/PlGF-ratio in the first did not increase the odds of an AO in the subsequent pregnancy. CONCLUSIONS The prevalence of AOs decreases in subsequent pregnancies. Our finding that the sFlt-1/PlGF-ratio of the first was not related to the outcome of the subsequent pregnancy suggests that angiogenic markers are only a within-pregnancy short-term tool to assess AOs.

Abstract
Importance There is no consensus regarding the best method for prediction of hypertensive disorders of pregnancy (HDP), including gestational hypertension and preeclampsia. Objective To determine predictive ability in early pregnancy of large-scale proteomics for prediction of HDP. Design, Setting, and Participants This was a nested case-control study, conducted in 2022 to 2023, using clinical data and plasma samples collected between 2010 and 2013 during the first trimester, with follow-up until pregnancy outcome. This multicenter observational study took place at 8 academic medical centers in the US. Nulliparous individuals during first-trimester clinical visits were included. Participants with HDP were selected as cases; controls were selected from those who delivered at or after 37 weeks without any HDP, preterm birth, or small-for-gestational-age infant. Age, self-reported race and ethnicity, body mass index, diabetes, health insurance, and fetal sex were available covariates. Exposures Proteomics using an aptamer-based assay that included 6481 unique human proteins was performed on stored plasma. Covariates were used in predictive models. Main Outcomes and Measures Prediction models were developed using the elastic net, and analyses were performed on a randomly partitioned training dataset comprising 80% of study participants, with the remaining 20% used as an independent testing dataset. Primary measure of predictive performance was area under the receiver operating characteristic curve (AUC). Results This study included 753 HDP cases and 1097 controls with a mean (SD) age of 26.9 (5.5) years. Maternal race and ethnicity were 51 Asian (2.8%), 275 non-Hispanic Black (14.9%), 275 Hispanic (14.9%), 1161 non-Hispanic White (62.8% ), and 88 recorded as other (4.8%), which included those who did not identify according to these designations. The elastic net model, allowing for forced inclusion of prespecified covariates, was used to adjust protein-based models for clinical and demographic variables. Under this approach, no proteins were selected to augment the clinical and demographic covariates. The predictive performance of the resulting model was modest, with a training set AUC of 0.64 (95% CI, 0.61-0.67) and a test set AUC of 0.62 (95% CI, 0.56-0.68). Further adjustment for study site yielded only minimal changes in AUCs. Conclusions and Relevance In this case-control study with detailed clinical data and stored plasma samples available in the first trimester, an aptamer-based proteomics panel did not meaningfully add to predictive utility over and above clinical and demographic factors that are routinely available.

Abstract
OBJECTIVE To evaluate differences in health care utilization and guideline adherence for postpartum individuals with hypertensive disorders of pregnancy (HDP) who are engaged in a remote monitoring program, compared with usual care. METHODS This was a retrospective cohort study of postpartum individuals with HDP who delivered between March 2019 and June 2023 at a single institution. The primary exposure was enrollment in a remote hypertension management program that relies on patient home blood pressure (BP) measurement and centralized nursing team management. Patients enrolled in the program were compared with those receiving usual care. Outcomes included postpartum readmission, office visit within 6 weeks postpartum, BP measurement within 10 days, and initiation of antihypertensive medication. We performed multivariable logistic and conditional regression in a propensity score matched cohort. Propensity scores, generated by modeling likelihood of program participation, were assessed for even distribution by group, ensuring standardized bias of less than 10% after matching. RESULTS Overall, 12,038 eligible individuals (6,556 participants, 5,482 in the control group) were included. Program participants were more likely to be White, commercially insured, be diagnosed with preeclampsia, and have higher prenatal and inpatient postpartum BPs. Differences in baseline factors were well-balanced after implementation of propensity score. Program enrollment was associated with lower 6-week postpartum readmission rates, demonstrating 1 fewer readmission for every 100 individuals in the program (propensity score-matched adjusted risk difference [aRD] -1.5, 95% CI, -2.6 to -0.46; adjusted risk ratio [aRR] 0.78, 95% CI, 0.65-0.93). For every 100 individuals enrolled in the program, 85 more had a BP recorded within 10 days (propensity score-matched aRD 85.4, 95% CI, 84.3-86.6), and six more had a 6-week postpartum office visit (propensity score-matched aRD 5.7, 95% CI, 3.9-7.6). Program enrollment was also associated with increased initiation of an antihypertensive medication postpartum (propensity score-matched aRR 4.44, 95% CI, 3.88-5.07). CONCLUSION Participation in a postpartum remote BP monitoring program was associated with fewer postpartum hospital readmissions, higher attendance at postpartum visits, improved guideline adherence, and higher rates of antihypertensive use.

Abstract
Introduction This module teaches core knowledge and skills for undergraduate medical education in reproductive health, providing instruction in the management of normal and abnormal pregnancy and labor utilizing interactive small-group flipped classroom methods and case-based instruction. Methods Advance preparation materials were provided before the education session. The 2-hour session was facilitated by clinical educators using a faculty guide. Using voluntary surveys, we collected data to measure satisfaction among obstetrics and gynecology clerkship students and facilitators following each education session. Results Capturing six clerkships spanning 9 months, 116 students participated, and 64 students completed the satisfaction survey, with 97% agreeing that the session was helpful in applying knowledge and principles to common clinical scenarios. Most students (96%) self-reported that they achieved the session's learning objectives utilizing prework and interactive small-group teaching. Nine clinical instructors completed the survey; all agreed the provided materials allowed them to facilitate active learning, and the majority (89%) agreed they spent less time preparing to teach this curriculum compared to traditional didactics. Discussion This interactive flipped classroom session meets clerkship learning objectives related to the management of pregnancy and labor using standardized materials. The curriculum reduced preparation time for clinical educators as well.

Abstract
BACKGROUND Optimal first-trimester anticoagulation is still challenging in pregnant women with mechanical heart valves (MHVs) requiring high-dose warfarin. This multicenter prospective study aims to determine the optimal anticoagulation regimens for pregnant patients with MHVs. METHODS All women were allocated to one of three treatment options during first trimester including lone low-molecular-weight heparin (LMWH), combination of LMWH + 2.5 mg warfarin, and LMWH+4 mg warfarin. Primary maternal outcome included a combination of death, thromboembolism, severe bleeding, and need for treatment of mechanical valve thrombosis (MVT). Any fetal loss was determined as primary fetal outcome. RESULTS The study included 78 pregnancies in 65 women with MHVs. Primary maternal outcome rate was 44%, 12.5%, 3.5%, respectively. The rates of primary maternal outcome (44 vs 3.5%, P < .001), obstructive MVT (16 vs 0%, P = .04), MVT requiring treatment (28 vs 0%, P = .003), and cerebral embolism (24 vs 3.4%, P = .041) were found to be significantly higher in lone LMWH group compared to LMWH + 4 mg warfarin group. Moreover, the rates of primary maternal outcome (12.5 vs 44%, P = .015) and treatment for MHV thrombus (4.2 vs 28%, P = .049) were significantly lower in LMWH + 2.5 mg warfarin group compared to lone LMWH group. The incidences of fetal loss were 8 (32%) in the lone LMWH group, 8 (33.3%) in LMWH + 2.5 mg warfarin group, and 11 (37.9%) in LMWH + 4 mg warfarin group (P = .890 for 3-group).Warfarin related-embryopathy was not observed in any case. CONCLUSIONS The combined anticoagulation strategy of LMWH plus low-dose warfarin during the first trimester of pregnancy may result in less maternal complications with comparable fetal outcomes in patients with MHVs. CONDENSED ABSTRACT Low-molecular-weight heparin (LMWH) is thought to be safer for the fetus, however it is suspected to be less protective for the mother. To solve this dilemma, the authors suggested a novel anticoagulation strategy in pregnant women with prosthetic valves. Seventy-eight pregnancies of 65 women (median age 32 [27-35] years) were included in the study. A combination of LMWH and a reduced dose warfarin were associated with low rates of thrombus-related complications in pregnant patients with mechanical heart valves.

Abstract
Neurologic emergencies in pregnancy require prompt evaluation and early, focused intervention to improve neurologic outcomes for the affected person and to avoid further injury. Neurologic events in pregnancy, although rare, present a time of extreme risk of permanent injury for the person who is pregnant. Therefore, obstetric clinicians should be well versed in the risk factors for potential neurologic events and understand the symptoms and events that should prompt evaluation for a neurologic event. In addition, they should support other specialties in aggressive and early neurologic care for the patient to improve outcomes while assessing fetal well-being and care optimization for the dyad. Obstetric clinicians can uniquely provide knowledge of changes in pregnancy physiology that can increase the risk of neurologic events, as well as change the treatment of these events. For all patients with neurologic events, "time is brain." Therefore, it is important to be aware of changes in common presenting pregnancy concerns that should prompt evaluation for other pathogeneses. Finally, pregnancy care teams should be prepared to begin the initial stabilization and management of acute neurologic emergencies, including seizure, stroke, and meningitis, while seeking aid from other medical and neurologic specialists who can support their care and interventions. Early and aggressive interventions for individuals with neurologic events during pregnancy and postpartum are critical to the overall well-being of the dyad.

Abstract
PURPOSE OF REVIEW Hypertensive disorders of pregnancy (HDP) pose a significant threat to maternal cardiovascular health, with emerging research shedding light on the enduring risks beyond the gestational period. This review highlights updates regarding cardiovascular risks associated with HDP and their implications for long-term health. RECENT FINDINGS Patients with a history of HDP are at an elevated risk of developing chronic hypertension, ischemic heart disease, stroke, valvular heart disease, and heart failure.Not surprisingly, patients with HDP experience higher rates of maternal and fetal adverse events in the antepartum and immediate postpartum periods, with high readmission rates for cardiovascular complications. The high risk of chronic hypertension after a HDP then leads to the development of subclinical disease over 5-10 years with overt cardiovascular disease becoming most prevalent in the decades following pregnancy. Early hypertension management in the antepartum and postpartum periods has lifelong health benefits and highlights the need for seamless postpartum transitions with close blood pressure monitoring and cardiovascular risk mitigation. SUMMARY HDP significantly increases the risk of short and long-term adverse cardiovascular events. Integrated healthcare models that assess and address postpartum cardiovascular risk are necessary to improve the cardiovascular health and longevity of those effected by HDP.

Abstract
BACKGROUND The placenta is a unique and pivotal organ in reproduction, controlling crucial growth and cell differentiation processes that ensure a successful pregnancy. Placental development is a tightly regulated and dynamic process, in which the transforming growth factor beta (TGFβ) superfamily plays a central role. This family of pleiotropic growth factors is heavily involved in regulating various aspects of reproductive biology, particularly in trophoblast differentiation during the first trimester of pregnancy. TGFβ signalling precisely regulates trophoblast invasion and the cell transition from cytotrophoblasts to extravillous trophoblasts, which is an epithelial-to-mesenchymal transition-like process. Later in pregnancy, TGFβ signalling ensures proper vascularization and angiogenesis in placental endothelial cells. Beyond its role in trophoblasts and endothelial cells, TGFβ signalling contributes to the polarization and function of placental and decidual macrophages by promoting maternal tolerance of the semi-allogeneic foetus. Disturbances in early placental development have been associated with several pregnancy complications, including preeclampsia (PE) which is one of the severe complications. Emerging evidence suggests that TGFβ is involved in the pathogenesis of PE, thereby offering a potential target for intervention in the human placenta. OBJECTIVE AND RATIONALE This comprehensive review aims to explore and elucidate the roles of the major members of the TGFβ superfamily, including TGFβs, bone morphogenetic proteins (BMPs), activins, inhibins, nodals, and growth differentiation factors (GDFs), in the context of placental development and function. The review focusses on their interactions within the major cell types of the placenta, namely trophoblasts, endothelial cells, and immune cells, in both normal pregnancies and pregnancies complicated by PE throughout pregnancy. SEARCH METHODS A literature search was carried out using PubMed and Google Scholar, searching terms: 'TGF signalling preeclampsia', 'pregnancy TGF signalling', 'preeclampsia tgfβ', 'preeclampsia bmp', 'preeclampsia gdf', 'preeclampsia activin', 'endoglin preeclampsia', 'endoglin pregnancy', 'tgfβ signalling pregnancy', 'bmp signalling pregnancy', 'gdf signalling pregnancy', 'activin signalling pregnancy', 'Hofbauer cell tgfβ signalling', 'placental macrophages tgfβ', 'endothelial cells tgfβ', 'endothelium tgfβ signalling', 'trophoblast invasion tgfβ signalling', 'trophoblast invasion Smad', 'trophoblast invasion bmp', 'trophoblast invasion tgfβ', 'tgfβ preeclampsia', 'tgfβ placental development', 'TGFβ placental function', 'endothelial dysfunction preeclampsia tgfβ signalling', 'vascular remodelling placenta TGFβ', 'inflammation pregnancy tgfβ', 'immune response pregnancy tgfβ', 'immune tolerance pregnancy tgfβ', 'TGFβ pregnancy NK cells', 'bmp pregnancy NK cells', 'bmp pregnancy tregs', 'tgfβ pregnancy tregs', 'TGFβ placenta NK cells', 'TGFβ placenta tregs', 'NK cells preeclampsia', 'Tregs preeclampsia'. Only articles published in English until 2023 were used. OUTCOMES A comprehensive understanding of TGFβ signalling and its role in regulating interconnected cell functions of the main placental cell types provides valuable insights into the processes essential for successful placental development and growth of the foetus during pregnancy. By orchestrating trophoblast invasion, vascularization, immune tolerance, and tissue remodelling, TGFβ ligands contribute to the proper functioning of a healthy maternal-foetal interface. However, dysregulation of TGFβ signalling has been implicated in the pathogenesis of PE, where the shallow trophoblast invasion, defective vascular remodelling, decreased uteroplacental perfusion, and endothelial cell and immune dysfunction observed in PE, are all affected by an altered TGFβ signalling. WIDER IMPLICATIONS The dysregulation of TGFβ signalling in PE has important implications for research and clinical practice. Further investigation is required to understand the underlying mechanisms, including the role of different ligands and their regulation under pathophysiological conditions, in order to discover new therapeutic targets. Distinguishing between clinically manifested subtypes of PE and studying TGFβ signalling in different placental cell types holistically is an important first step. To put this knowledge into practice, pre-clinical animal models combined with new technologies are needed. This may also lead to improved human research models and identify potential therapeutic targets, ultimately improving outcomes for affected pregnancies and reducing the burden of PE.

Umbilical artery half peak systolic velocity deceleration time: a novel Doppler parameter for prediction of neonatal outcomes in pregnant women with preeclampsia. Arch Gynecol Obstet 2024; 310:245-251. [PMID: 37865627 DOI: 10.1007/s00404-023-07248-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Accepted: 09/27/2023] [Indexed: 10/23/2023]
Abstract
PURPOSE To assess the effectiveness of half peak systolic velocity deceleration time (hPSV-DT) in predicting neonatal outcomes in pregnant women with preeclampsia and to compare its usefulness with the conventional umbilical artery (UA) pulsatility index (PI) approach. METHODS A prospective cohort study was conducted among pregnant women with preeclampsia who were admitted to the Department of Perinatology, Ministry of Health Ankara City Hospital between 01 September 2022 and 01 January 2023 at 28-41 weeks gestational age. 55 patients were divided into two groups: the study group with UA hPSV-DT value < 5th percentile (n = 22) and the control group with UA hPSV-DT value ≥ 5th percentile (n = 33). UA hPSV-DT calculates the time in milliseconds needed to halve the maximal velocity of the UA waveform using Doppler ultrasonography. RESULTS Birth weight, gestational age at birth, 1st minute APGAR, 5th minute APGAR, and umbilical cord pH values were significantly lower in the anormal hPSV-DT group (p < 0.05). Additionally, the rates of admission to NICU, respiratory distress syndrome (RDS), delivery time < 34 weeks, and birth weight < 2500 g were significantly more frequent in the anormal hPSV-DT group compared to the normal hPSV-DT group (p < 0.05). UA-PI > 95th percentile was detected in only 2 (8%) of 23 patients whose newborns were admitted to the NICU (p = 0.149), while hPSV-DT < 5th percentile was detected in 16 (69%) of 23 patients (p < 0.001). According to ROC analysis, the area under the curve was 0.82 (95% CI 0.06-0.28) for admission to the NICU. The best balance of sensitivity/specificity in ROC curves was 221.5 (82.6% sensitivity, 69.1% specificity, p < 0.001). CONCLUSION UA hPSV-DT was successful in predicting composite adverse perinatal outcomes in pregnant women with preeclampsia. It is a promising novel method that is accurate, quantitative, reproducible, and easily applicable. With further studies, this method may be a primary diagnostic tool in the management of high-risk pregnancies and in determining the optimal timing of delivery.

Early postpartum blood pressure screening is associated with increased detection of cardiovascular risk factors in women with hypertensive disorders of pregnancy. Am Heart J 2024; 273:130-139. [PMID: 38582139 PMCID: PMC11162911 DOI: 10.1016/j.ahj.2024.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 03/25/2024] [Accepted: 03/28/2024] [Indexed: 04/08/2024]
Abstract
BACKGROUND Hypertensive disorders of pregnancy (HDP), including gestational hypertension, preeclampsia, and eclampsia, are risk factors for cardiovascular (CV) disease. Guidelines recommend that women with HDP be screened for the development of hypertension (HTN) within 6-12 months postpartum. However, the extent to which this early blood pressure (BP) screening is being performed and the impact on detection of CV risk factors is unknown. METHODS Women with HDP and without pre-existing hypertension (HTN) who had at least 6 months of clinical follow-up were categorized by postpartum BP screening status: early BP screen (6-12 months after delivery) or late BP screen (≥12 months after delivery). Multivariable logistic regression identified factors associated with early screening. Multivariable Cox proportional hazards modeling examined the association between early screening and detection of incident CV risk factors: HTN, prediabetes, diabetes mellitus type 2, or hyperlipidemia. RESULTS Among 4194 women with HDP, 1172 (28%) received early BP screening. Older age, pre-existing hyperlipidemia, diabetes, sickle cell disease, hypothyroidism, gestational diabetes, and delivery during or after 2014 were independently associated with early BP screening, whereas Hispanic ethnicity was associated with late BP screening. Early BP screening was most commonly performed at a primary care visit. After a median follow-up of 3.7 years, 1012 (24%) women had at least 1 new risk factor detected. Even after adjustment for baseline risk, women receiving early BP screening had a significantly higher rate of incident CV risk factor detection than women receiving late BP screening (56% vs 28%; adj. HR 2.70, 95%CI: 2.33-3.23, P < .001). CONCLUSIONS Early postpartum BP screening was performed in a minority of women with HDP, but was associated with greater detection of CV risk factors. More intensive postpartum CV screening and targeted interventions are needed to optimize CV health in this high-risk population of women with HDP.

Abstract
PURPOSE To investigate the effect of intravenous MgSO4 on maternal cerebral hemodynamics as well as the association between altered Doppler indices of the ophthalmic arteries and ocular lesions in patients with preeclampsia. METHODS After each of the 15 included patients was diagnosed with preeclampsia, MgSO4 was infused followed by transcranial Doppler tests of the indices of the ophthalmic, anterior, middle, posterior cerebral, vertebral, and basilar arteries, followed by a second MgSO4 infusion. The peak, mean, diastolic velocity, and pulsatile and resistance indices of each artery were automatically measured during testing. Based on the emergent data, the cerebral perfusion pressure, resistance-area product, and cerebral flow index were calculated. RESULTS The cerebral perfusion pressure of the posterior cerebral arteries significantly decreased following the infusion of MgSO4 (p < 0.05). Before the infusion of MgSO4, cerebral perfusion pressure and cerebral flow index of the ophthalmic arteries were significantly increased (p < 0.05) in the preeclamptic pregnant patients with ocular lesions compared those without ocular lesions. After the infusion of MgSO4, the cerebral perfusion pressure and cerebral flow index of both ophthalmic arteries were slightly decreased, but the difference was not significant. CONCLUSIONS Altered Doppler indices following the infusion of MgSO4 suggest significant changes in the hemodynamics of the posterior cerebral and ophthalmic arteries that are particularly related to the neurological signs and symptoms of women with preeclampsia. These findings may improve the understanding of the mechanism of the cerebral complications of preeclampsia. Advancing comprehension of these underlying mechanisms is postulated to play a pivotal role in the mitigation of hypertensive encephalopathy associated with preeclampsia.

Abstract
OBJECTIVE We aimed to examine the association of clinical risk factors and placental lesions, in gestations complicated with preeclampsia, with the need for antihypertensive treatment in the early postpartum period. METHODS The computerized files and placental reports of all singleton deliveries at 24.0-42.0 weeks complicated by preeclampsia were reviewed between January 2013 and October 2020. Obstetric characteristics and placental lesions were compared between patients who required antihypertensive treatment in the early postpartum period and those who did not (control group). Placentas were classified into maternal and fetal malperfusion lesions and inflammatory responses. RESULTS As compared to controls (n = 200), the anti-hypertensive treatment group (n = 95) was characterized by increased rates of preterm birth, preeclampsia with severe features, and cesarean delivery (p < 0.001 for all). More placental hematomas (p = 0.01) and placental maternal vascular lesions (p = 0.03) were observed in the antihypertensive treatment group as compared to controls. In adjusted logistic regression analysis, gestational age (OR 0.86, 95% CI 0.79-0.93, p = 0.001) and preeclampsia with severe features (OR 8.89, 95% CI 3.18-14.93 p < 0.001) were found to be independently associated with the need for postpartum antihypertensive treatment. CONCLUSION Placental vascular lesions are more common in preeclamptic patients who need postpartum antihypertensive treatment, yet only early onset of preeclampsia with severe features was found to be independently associated with antihypertensive treatment in the early postpartum period.

Abstract
BACKGROUND Continuous glucose monitoring has facilitated the evaluation of dynamic changes in glucose throughout the day and their effect on fetal growth abnormalities in pregnancy. However, studies of multiple continuous glucose monitoring metrics combined and their association with other adverse pregnancy outcomes are limited. OBJECTIVE This study aimed to (1) use machine learning techniques to identify discrete glucose profiles based on weekly continuous glucose monitoring metrics in pregnant individuals with pregestational diabetes mellitus and (2) investigate their association with adverse pregnancy outcomes. STUDY DESIGN This study analyzed data from a retrospective cohort study of pregnant patients with type 1 or 2 diabetes mellitus who used Dexcom G6 continuous glucose monitoring and delivered a nonanomalous, singleton pregnancy at a tertiary center between 2019 and 2023. Continuous glucose monitoring data were collapsed into 39 weekly glycemic measures related to centrality, spread, excursions, and circadian cycle patterns. Principal component analysis and k-means clustering were used to identify 4 discrete groups, and patients were assigned to the group that best represented their continuous glucose monitoring patterns during pregnancy. Finally, the association between glucose profile groups and outcomes (preterm birth, cesarean delivery, preeclampsia, large-for-gestational-age neonate, neonatal hypoglycemia, and neonatal intensive care unit admission) was estimated using multivariate logistic regression adjusted for diabetes mellitus type, maternal age, insurance, continuous glucose monitoring use before pregnancy, and parity. RESULTS Of 177 included patients, 90 (50.8%) had type 1 diabetes mellitus, and 85 (48.3%) had type 2 diabetes mellitus. This study identified 4 glucose profiles: (1) well controlled; (2) suboptimally controlled with high variability, fasting hypoglycemia, and daytime hyperglycemia; (3) suboptimally controlled with minimal circadian variation; and (4) poorly controlled with peak hyperglycemia overnight. Compared with the well-controlled profile, the suboptimally controlled profile with high variability had higher odds of a large-for-gestational-age neonate (adjusted odds ratio, 3.34; 95% confidence interval, 1.15-9.89). The suboptimally controlled with minimal circadian variation profile had higher odds of preterm birth (adjusted odds ratio, 2.59; 95% confidence interval, 1.10-6.24), cesarean delivery (adjusted odds ratio, 2.76; 95% confidence interval, 1.09-7.46), and neonatal intensive care unit admission (adjusted odds ratio, 4.08; 95% confidence interval, 1.58-11.40). The poorly controlled profile with peak hyperglycemia overnight had higher odds of preeclampsia (adjusted odds ratio, 2.54; 95% confidence interval, 1.02-6.52), large-for-gestational-age neonate (adjusted odds ratio, 3.72; 95% confidence interval, 1.37-10.4), neonatal hypoglycemia (adjusted odds ratio, 3.53; 95% confidence interval, 1.37-9.71), and neonatal intensive care unit admission (adjusted odds ratio, 3.15; 95% confidence interval, 1.20-9.09). CONCLUSION Discrete glucose profiles of pregnant individuals with pregestational diabetes mellitus were identified through joint consideration of multiple continuous glucose monitoring metrics. Prolonged exposure to maternal hyperglycemia may be associated with a higher risk of adverse pregnancy outcomes than suboptimal glycemic control characterized by high glucose variability and intermittent hyperglycemia.

Abstract
Studies on the associations of blood pressure (BP) and the risk of venous thromboembolism (VTE) had been performed neither among pregnant women nor in Chinese population. This study included participants of pregnant women from a retrospective multicenter cohort, between May 2020 and April 2023. Systolic BP (SBP) and diastolic BP (DBP) of the participants were measured in the third trimester. The incidences of VTE (including deep venous thrombosis and/or pulmonary embolism) at 42 days postpartum were followed. With regards to SBP, pregnant women in the Q1 (≤114 mmHg), Q2 (115-122 mmHg), and Q4 group (≥131 mmHg) had increased risk of VTE than those in Q3 group (123-130 mmHg), with ORs 4.48 [1.69, 11.85], 3.52 [1.30, 9.59], and 3.17 [1.12, 8.99], respectively. Compared with pregnant women with the Q4 of DBP (≥85 mmHg), women of Q1 (≤71 mmHg) were found to have elevated risk of VTE (OR 2.73 [1.25, 5.96]). A one standard deviation decrease of DBP (9 mmHg) was related with 37% elevated risk of VTE (OR 1.37 [1.05, 1.79]). This study demonstrated a U-shaped association of SBP in the third trimester and VTE postpartum and inverse association of DBP in the third trimester and VTE postpartum.

JAMA Netw Open 2024; 7:e2422500. [PMID: 39012630 PMCID: PMC11252898 DOI: 10.1001/jamanetworkopen.2024.22500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 05/02/2024] [Indexed: 07/17/2024] Open
Abstract
Importance More than 30% of pregnant people have at least 1 chronic medical condition, and nearly 20% develop gestational diabetes or pregnancy-related hypertension, increasing the risk of future chronic disease. While these individuals are often monitored closely during pregnancy, they face major barriers when transitioning to primary care following delivery, due in part to a lack of health care support for this transition. Objective To evaluate the impact of an intervention designed to improve postpartum primary care engagement by reducing patient administrative burden and information gaps. Design, Setting, and Participants An individual-level randomized clinical trial was conducted from November 3, 2022, to October 11, 2023, at 1 hospital-based and 5 community-based outpatient obstetric clinics affiliated with a large academic medical center. Participants included English- and Spanish-speaking pregnant or recently postpartum adults with obesity, anxiety, depression, diabetes, chronic hypertension, gestational diabetes, or pregnancy-related hypertension and a primary care practitioner (PCP) listed in their electronic health record. Intervention A behavioral economics-informed intervention bundle, including default scheduling of postpartum PCP appointments and tailored messages. Main Outcome and Measures Completion of a PCP visit for routine or chronic condition care within 4 months of delivery was the primary outcome, ascertained directly by reviewing the patient's electronic health record approximately 5 months after their estimated due date. Intention-to-treat analysis was conducted. Results A total of 360 patients were randomized (control, 176; intervention, 184). Individuals had a mean (SD) age of 34.1 (4.9) years and median gestational age of 36.3 (IQR, 34.0-38.6) weeks at enrollment. The distribution of self-reported race and ethnicity was 6.8% Asian, 7.4% Black, 68.6% White, and 15.0% multiple races or other. Most participants (75.4%) had anxiety or depression, 16.1% had a chronic or pregnancy-related hypertensive disorder, 19.5% had preexisting or gestational diabetes, and 40.8% had a prepregnancy body mass index of 30 or greater. Medicaid was the primary payer for 21.2% of patients. Primary care practitioner visit completion within 4 months occurred in 22.0% (95% CI, 6.4%-28.8%) of individuals in the control group and 40.0% (95% CI, 33.1%-47.4%) in the intervention group. In regression models accounting for randomization strata, the intervention increased PCP visit completion by 18.7 percentage points (95% CI, 9.1-28.2 percentage points). Intervention participants also had fewer postpartum readmissions (1.7% vs 5.8%) and increased receipt of the following services by a PCP: blood pressure screening (42.8% vs 28.3%), weight assessment (42.8% vs 27.7%), and depression screening (32.8% vs 16.8%). Conclusions and Relevance The findings of this randomized clinical trial suggest that the current lack of support for postpartum transitions to primary care is a missed opportunity to improve recently pregnant individual's short- and long-term health. Reducing patient administrative burdens may represent relatively low-resource, high-impact approaches to improving postpartum health and well-being. Trial Registration ClinicalTrials.gov Identifier: NCT05543265.

Decreased postpartum exercise capacity after a diagnosis of pre-eclampsia: Implications for CVD risk prediction. Am Heart J 2024:S0002-8703(24)00147-9. [PMID: 38944263 DOI: 10.1016/j.ahj.2024.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 06/03/2024] [Accepted: 06/05/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND Hypertensive disorders of pregnancy (HDP) are associated with increased long-term risk for cardiometabolic risk factors (chronic hypertension [HTN], obesity, diabetes) and heart failure. Exercise capacity is a known predictor of heart failure in patients with normal resting cardiac filling pressures. In this prospective observational cohort study, we sought to identify predictors of reduced postpartum exercise capacity in participants with normotensive vs. preeclamptic pregnancies. METHODS Preeclampsia (PreE) and normotensive subjects were enrolled to undergo bedside echocardiography within 48 hours of delivery, and rest/exercise echocardiography 12 weeks postpartum. RESULTS Recruited subjects (n=68) were grouped according to their blood pressure as: a) normotensive pregnancy n=15; b) PreE with normotensive postpartum (PreE-Resolved, n=36); c) PreE with persistent postpartum HTN (PreE-HTN, n=17). At enrollment, a significantly higher percentage of subjects in the PreE-HTN group were Black. Compared to normotensive and PreE-Resolved subjects, those with PreE-HTN demonstrated higher resting systolic blood pressure (SBP, 112 [normotensive] vs 112 [PreE-Resolved] vs 134 [PreE-HTN], p<0.001) and diastolic blood pressure (DBP, 70.0 vs 72.5 vs 85.0, p<0.001), and significantly less postpartum weight loss (9.6% vs 13.6% vs 3.8%, p<0.001). Following Bruce protocol stress testing, PreE-HTN subjects demonstrated achieved significantly lower exercise duration (10.4 vs 10.2 vs 7.9 minutes, p = 0.001). Subjects with PreE-HTN also demonstrated evidence of exercise-induced diastolic dysfunction as assessed by peak exercise lateral e' (18.0 vs 18.0 vs 13.5, p=0.045) and peak exercise tricuspid regurgitation velocity (TR Vm, 2.4 vs 3.0 vs 3.1, p = 0.045). Exercise duration was negatively associated with gravidity (R=-0.27, p=0.029) and postpartum LV mass index (R=-0.45, p<0.001), resting average E/e' (R=-0.51, p<0.001), BMI (R=-0.6, p<0.001) and resting SBP (R=-0.51, p<0.001). CONCLUSIONS Postpartum exercise stress testing capacity is related to readily available clinical markers including pregnancy factors, echocardiographic parameters and unresolved cardiometabolic risk factors.

Abstract
OBJECTIVES To improve timely treatment and follow-up of birthing individuals with severe hypertension. STUDY DESIGN A quality improvement (QI) initiative was implemented at an academic tertiary care center in the United States of America for individuals with obstetric hypertensive emergencies. Statistical process control charts were utilized to track process measures and interventions tested through plan-do-study-act cycles. Measures were disaggregated by race and ethnicity to identify and improve disparities. MAIN OUTCOME MEASURES Treatment of hypertensive events within 60 min, receipt of blood pressure (BP) device at discharge and completed postpartum follow-up BP check within 7 days of discharge. RESULTS All process measures showed statistically significant improvements. The primary process measure, timely treatment of hypertensive emergencies, improved from 29 % to 76 %. Receipt of BP device improved from 37 % to 91 % and follow-up BP checks from 58 % to 81 %. No racial or ethnic disparities were noted at baseline or after interventions. Readmission rates within 6 weeks of delivery increased from 2.3 % to 6.1 % for the cohort with no severe morbidity or mortality events after discharge. Strategies associated with improvement included project launch with establishment of the "why," telehealth, simulation, a video display of quality metrics on the birthing unit, promoting BP cuff access, and automated orders. CONCLUSIONS This comprehensive QI initiative provides novel improvement strategies for the management of individuals with severe hypertensive disorders of pregnancy for the timely treatment of severe BP, attainment of home BP devices, and follow-up after discharge. Quality improvement methodology is practical and essential for achieving guideline-concordant care.

Abstract
Background Preeclampsia (PE) is a serious pregnancy complication affecting 5-8% of pregnancies globally. It is a leading cause of maternal and neonatal morbidity and mortality. Despite its prevalence, the underlying mechanisms of PE remain unclear. This study aimed to determine the potential role of vasorin (VASN) in PE pathogenesis by investigating its levels in extracellular vesicles (EV) and its effects on vascular function. Methods & Results We conducted unbiased proteomics on urine-derived EV from severe PE (sPE) and normotensive pregnant women (NTP), identifying differential protein abundances. Out of one hundred and twenty proteins with ≥ ±1.5-fold regulation at P<0.05 between sPE and NTP, we focused on Vasorin (VASN), which is downregulated in sPE in urinary EV, in plasma EV and in the placenta and is a known regulator of vascular function. We generated EV with high VASN content from both human and murine placenta explants (Plex EV), which recapitulated disease-state-dependent effects on vascular function observed when treating murine aorta rings (MAR) or human aortic endothelial cells (HAEC) with murine or human plasma-derived EV. In normal murine pregnancy, VASN increases with gestational age (GA), and VASN is decreased in plasma EV, in placenta tissue and in Plex EV after intravenous administration of adenovirus encoding short FMS-like tyrosine kinase 1 (sFLT-1), a murine model of PE (murine-PE). VASN is decreased in plasma EV, in placenta tissue and in EV isolated from conditioned media collected from placenta explants (Plex EV) in patients with sPE as compared to NTP. Human sPE and murine-PE plasma EV and Plex EV impair migration, tube formation, and induces apoptosis in human aortic endothelial cells (HAEC) and inhibit acetylcholine-induced vasorelaxation in murine vascular rings (MAR). VASN over-expression counteracts the effects of sPE EV treatment in HAEC and MAR. RNA sequencing revealed that over-expression or knock down of VASN in HAEC results in contrasting effects on transcript levels of hundreds of genes associated with vasculogenesis, endothelial cell proliferation, migration and apoptosis. Conclusions The data suggest that VASN, delivered to the endothelium via EV, regulates vascular function and that the loss of EV VASN may be one of the mechanistic drivers of PE. CLINICAL PERSPECTIVE What is NewVASN in circulating plasma EV in sPE is reduced compared with VASN content in plasma EV of gestational age-matched pregnant women.VASN is encapsulated and transported in EV and plays a pro-angiogenic role during pregnancy.VASN should be explored both for its pro-angiogenic mechanistic role and as a novel biomarker and potential predictive diagnostic marker for the onset and severity of PE.What Are the Clinical Implications?VASN plays a role in maintaining vascular health and the normal adaptive cardiovascular response in pregnancy. A decrease of VASN is observed in sPE patients contributing to cardiovascular maladaptation.Strategies to boost diminished VASN levels and/or to pharmacologically manipulate mechanisms downstream of VASN may be explored for potential therapeutic benefit in PE.The decrease in EV-associated VASN could potentially be used as a (predictive) biomarker for PE.

Abstract
Chronic Intervillositis of Unknown Etiology (CIUE) is a rare idiopathic inflammatory disorder of the placenta. The evidence suggests an increased risk for poor obstetrical outcomes and a risk of recurrence as high as 100 %. This meta-analysis examined CIUE prevalence, recurrence, association with autoimmune disorders, reproductive outcomes, pregnancy complications, and the benefits of medical treatments. A systematic review, following PRISMA guidelines, involved a thorough search across multiple databases including Medline, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Evidence Based Medical Reviews, and Scopus. Out of 590 initially identified studies, 19 studies were included for both qualitative synthesis and meta-analysis after full-text review. Risk of bias was assessed using appropriate tools: The Risk Of Bias In Non-randomized Studies of Interventions tool was applied to twelve studies, while the Joanna Briggs Institute case series critical appraisal tool was used for seven studies. Our findings confirm that CIUE is a rare condition (0.7 %). CIUE is associated with decreased live birth rates (53 %), increased recurrent pregnancy loss (23 %), fetal loss beyond 22 weeks gestation (25 %), a higher prevalence of autoimmune diseases (14 %), and a recurrence rate of 30 % in subsequent pregnancies. Moreover, individuals with CIUE had higher rates of pregnancy complications, including gestational hypertension (19 %), intrauterine growth restriction (45 %), and preterm births (43 %). No significant improvement in live birth rate was observed among treated CIUE patients; however, caution is warranted when interpreting these findings due to the limited sample size. Future research in CIUE is crucial given its rarity and complexity.

Abstract
Preeclampsia (PE) is a serious condition that threatens pregnancy with severe sequelae on both the mother and infant. Early detection of PE will lead to favorable outcomes, and using readily available markers like hematological indices is an attractive choice. Examine the diagnostic utility of hematological indices in pregnant women to predict preeclampsia and its severity. In a retrospective case-control study that included 252 women, all had their complete blood picture evaluated during their first and third trimesters as part of their outpatient antenatal care during their pregnancy. They were also divided into 3 groups: healthy pregnant women (control), non-severe PE, and severe PE, each involving 84 women. The changes in platelet to lymphocyte ratio (PLR) between 1st and 3rd trimesters showed an excellent ability to differentiate between severe PE and control (area under the curve = 0.954, cutoff ≤ -5.45%) and a good ability to differentiate between severe PE and non-severe PE (area under the curve = 0.841, cutoff ≤ -7.89%). Neutrophil to lymphocyte ratio showed a good to excellent ability to differentiate between severe PE and non-severe PE compared to control in the first and third trimesters and the percentage change between them. Changes in neutrophil to lymphocyte ratio and PLR strongly predict preeclampsia and its severity since they offer more predictive values than measuring NLP and PLR at different stages of pregnancy individually.

Abstract
Background Though considerable studies suggesting connections between micronutrients and pregnancy complications, current evidence remains inconsistent and lacks causative confirmation. Our study aimed to explore the causal links between them with a two-sample Mendelian randomization (MR) analysis. Methods Genome-wide association studies (GWAS) data for circulating micronutrients were sourced from GWAS Catalog consortium and PubMed, while data for pregnancy outcomes, including gestational diabetes mellitus (GDM), gestational hypertension (GH), spontaneous abortion (SA), preterm birth (PTB), and stillbirth (SB), were retrieved from the UK Biobank and FinnGen consortia. Causal effects were appraised using inverse variance weighted (IVW), weighted median (WM), and MR-Egger, followed by sensitivity analyses and meta-analysis for validation. Results Genetically predicted higher vitamin E (OR = 0.993, 95% CI 0.987-0.998; p = 0.005) levels were inversely associated with SA risk. Consistent results were obtained in meta-analysis (OR = 0.99, 95% CI 0.99-1.00; p = 0.005). Besides, a potential positive causality between genetic predisposition to vitamin B12 and SB was identified in both IVW (OR = 0.974, 95% CI 0.953-0.996; p = 0.018) and WM analysis (OR = 0.965, 95% CI 0.939-0.993; p = 0.013). However, no causal relationships were observed between other analyzed circulating micronutrients and pregnancy complications. Conclusion This study offers compelling evidence of causal associations between circulating levels of vitamins E, B12 and the risk of SA and SB, respectively. These findings are pivotal for pregnancy complications screening and prevention, potentially guiding clinical practice and public health policies toward targeted nutritional interventions.

Abstract
Metabolic Syndrome (MetS) during pregnancy can lead to complications such as gestational diabetes mellitus (GDM) and hypertensive disorders. In this study, we sought to examine the influence of dietary fiber, from both food sources and soluble fiber supplementation, on the metabolic health and overall pregnancy outcomes of women at high risk of MetS. We conducted a randomized controlled trial involving 376 women between 11 and 13 weeks of gestation. To evaluate dietary fiber intake, we performed an exhaustive dietary component analysis using a food frequency questionnaire. Additionally, the participants in the intervention group received daily soluble fiber supplements until delivery. All participants underwent nutritional consultations and metabolic health assessments at three distinct stages of pregnancy (GW 11-13, GW 24-26, and GW 32-34). Our findings revealed a significant correlation between insufficient dietary fiber intake and an increased risk of GDM, even after adjusting for variables such as maternal age and pre-pregnancy BMI. We also noted that a high total dietary fiber intake was associated with reduced changes in triglyceride levels. In addition, the intervention group showed lower need for constipation medication, and soluble fiber supplementation may offer potential benefits for GDM patients. Importantly, our study verified the safety of long-term soluble fiber supplementation during pregnancy. Our results underscore the importance of adequate fiber intake, particularly from dietary sources, for the metabolic health of pregnant women. Moreover, our findings suggest that early fiber supplementation may benefit pregnant women experiencing constipation or those diagnosed with GDM.

Abstract
AIMS To elucidate the clinical and pathological characteristics of gestational diabetes mellitus (GDM) with high and low insulin resistance. METHODS In total, 1393 GDM and 1001 non-GDM singleton deliveries were included in this study. Insulin resistance subtypes were classified according to the HOMA2-IR value. Clinical data were analyzed using SPSS 26.0. Placenta samples were collected for pathological analysis. RESULTS Maternal age and fasting glucose were identified as independent risk factors for GDM with high insulin resistance (p < 0.01), while fasting glucose was the sole risk factor for GDM with low insulin resistance (p < 0.001). Fetal distress was associated with both of GDM subtypes (both p < 0.01), while anemia, fetal growth restriction, large for gestational age and intrahepatic cholestasis in pregnancy were related to specific GDM insulin resistance subtype. In addition, GDM with high insulin resistance showed an increase of syncytial knots with down-regulation of PI3K/AKT signaling, while GDM with low insulin resistance showed normal syncytial knot counts and up-regulation of PI3K/AKT signaling. CONCLUSIONS Our findings provide novel perspectives to the clinical and pathological comprehensions of GDM with high and low insulin resistance, which might facilitate the mechanism study of GDM and its precision pregnancy management.

Ahrens KA, Palmsten K, Lipkind HS, Ackerman-Banks CM, Grantham CO. Does reversible postpartum contraception reduce the risk of pregnancy condition recurrence? A longitudinal claims-based study from Maine. Ann Epidemiol 2024; 96:58-65. [PMID: 38885800 DOI: 10.1016/j.annepidem.2024.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 05/17/2024] [Accepted: 06/14/2024] [Indexed: 06/20/2024]
Abstract
PURPOSE To estimate the effect of reversible postpartum contraception use on the risk of recurrent pregnancy condition in the subsequent pregnancy and if this effect was mediated through lengthening the interpregnancy interval (IPI). METHODS We used data from the Maine Health Data Organization's Maine All Payer Claims dataset. Our study population was Maine women with a livebirth index pregnancy between 2007 and 2019 that was followed by a subsequent pregnancy starting within 60 months of index pregnancy delivery. We examined recurrence of three pregnancy conditions, separately, in groups that were not mutually exclusive: prenatal depression, hypertensive disorders of pregnancy (HDP), and gestational diabetes (GDM). Effective reversible postpartum contraception use was defined as any intrauterine device, implant, or moderately effective method (pills, patch, ring, injectable) initiated within 60 days of delivery. Short IPI was defined as ≤ 12 months. We used log-binomial regression models to estimate risk ratios and 95 % confidence intervals, adjusting for potential confounders. RESULTS Approximately 41 % (11,448/28,056) of women initiated reversible contraception within 60 days of delivery, the prevalence of short IPI was 26 %, and the risk of pregnancy condition recurrence ranged from 38 % for HDP to 55 % for prenatal depression. Reversible contraception initiation within 60 days of delivery was not associated with recurrence of the pregnancy condition in the subsequent pregnancy (aRR ranged from 0.97 to 1.00); however, it was associated with lower risk of short IPI (aRR ranged from 0.67 to 0.74). CONCLUSION(S) Although initiation of postpartum reversible contraception within 60 days of delivery lengthens the IPI, our findings suggest that it does not reduce the risk of prenatal depression, HDP, or GDM recurrence. This indicates a missed opportunity for providing evidence-based healthcare and health interventions in the intrapartum period to reduce the risk of recurrence.

Am J Hypertens 2024; 37:523-530. [PMID: 38501740 PMCID: PMC11176272 DOI: 10.1093/ajh/hpae034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 01/17/2024] [Accepted: 03/12/2024] [Indexed: 03/20/2024] Open
Abstract
BACKGROUND Preeclampsia in a first pregnancy is a strong risk factor for preeclampsia in a second pregnancy. Whether chronic hypertension developed after a first pregnancy (interpregnancy hypertension) affects the recurrence risk of preeclampsia is unknown. METHODS This is a population-based cohort study of 391,645 women with their first and second singleton births between 2006 and 2017. Exposure groups were women with preeclampsia in their first pregnancy, interpregnancy hypertension, or both risk factors. Women with neither risk factor were used as a reference group. We calculated the adjusted relative risk (aRR) with 95% confidence intervals (CIs) for overall preeclampsia in the second pregnancy as well as preterm (<37 gestational weeks) and term (≥37 gestational weeks) subgroups of the disease. RESULTS Women with preeclampsia in their first pregnancy who did or did not develop interpregnancy hypertension had rates of preeclampsia in their second pregnancy of 21.5% and 13.6%, respectively. In the same population, the corresponding rates of preterm preeclampsia were 5.5% and 2.6%, respectively. After adjusting for maternal factors, women with preeclampsia in their first pregnancy who developed interpregnancy hypertension and those who did not have almost the same risk of overall preeclampsia in their second pregnancy (aRRs with 95% CIs: 14.51; 11.77-17.89 and 12.83; 12.09-13.62, respectively). However, preeclampsia in the first pregnancy and interpregnancy hypertension had a synergistic interaction on the outcome of preterm preeclampsia (aRR with 95% CI 26.66; 17.44-40.80). CONCLUSIONS Women with previous preeclampsia who developed interpregnancy hypertension had a very high rate of preterm preeclampsia in a second pregnancy, and the two risk factors had a synergistic interaction.

Postpartum Ambulatory Blood Pressure Patterns Following New-Onset Hypertensive Disorders of Pregnancy. JAMA Cardiol 2024:2820070.

Abstract
Importance After a hypertensive disorder of pregnancy, hypertension can worsen in the postpartum period following hospital discharge. Risk factors for ongoing hypertension and associated outcomes have not been well characterized. Objective To identify risk factors and characterize outcomes for individuals with ongoing hypertension and severe hypertension following hospital discharge post partum through a hospital system's remote blood pressure (BP) management program. Design, Setting, and Participants This cohort study involved a population-based sample of individuals with a new-onset hypertensive disorder of pregnancy (preeclampsia or gestational hypertension) and no prepregnancy hypertension who delivered between September 2019 and June 2021. Participants were enrolled in a remote BP monitoring and management program at a postpartum unit at a referral hospital. Data analysis was performed from August 2021 to January 2023. Exposure Inpatient postpartum BP categories. Main Outcomes and Measures The primary outcomes were readmission and emergency department visits within the first 6 weeks post partum. Logistic regression was used to model adjusted odds ratios (aORs) and 95% CIs. Results Of 2705 individuals in the cohort (mean [SD] age, 29.8 [5.7] years), 2214 (81.8%) had persistent hypertension post partum after hospital discharge, 382 (14.1%) developed severe hypertension after discharge, and 610 (22.6%) had antihypertensive medication initiated after discharge. Individuals with severe hypertension had increased odds of postpartum emergency department visits (aOR, 1.85; 95% CI, 1.17-2.92) and hospital readmissions (aOR, 6.75; 95% CI, 3.43-13.29) compared with individuals with BP normalization. When inpatient postpartum BP categories were compared with outpatient home BP trajectories to inform optimal thresholds for inpatient antihypertensive medication initiation, there was significant overlap between postdischarge BP trajectories among those with inpatient systolic BP greater than or equal to 140 to 149 mm Hg and/or diastolic BP greater than or equal to 90 to 99 mm Hg and those with systolic BP greater than or equal to 150 mm Hg and/or diastolic BP greater than or equal to 100 mm Hg. Conclusions and Relevance This cohort study found that more than 80% of individuals with hypertensive disorders of pregnancy had ongoing hypertension after hospital discharge, with approximately 14% developing severe hypertension. These data support the critical role of remote BP monitoring programs and highlight the need for improved tools for risk stratification and consideration of liberalization of thresholds for medication initiation post partum.
