aspirin AND preeclampsia

Proper placentation during early pregnancy is a key factor for maintaining a healthy pregnancy. Placental insufficiency leads to critical complications such as preeclampsia, fetal growth restriction, and fetal demise. These complications are often associated with pathological findings of restricted remodeling and obstructive lesions of the myometrial spiral arteries, which have high recurrence rates during subsequent pregnancies. Currently, there are no pharmacological interventions other than aspirin for the prevention of preeclampsia...

BACKGROUND: Acute coronary syndrome (ACS) in young women is poorly understood due to underdiagnosis and undertreatment. One of the possible risk factors for ACS in young women is antiphospholipid syndrome (APS). Coronavirus disease 2019 (COVID-19) vaccination also emerged as one of the possible risk factors for ACS during the COVID-19 pandemic. CASE PRESENTATION: Our patient, a 39-year-old Batak woman with dyslipidemia and family history of cardiovascular disease, experienced chest pain slightly improved at rest accompanied by autonomic symptoms...

OBJECTIVES: To systematically evaluate the efficacy of low molecular weight heparin (LMWH) to prevent preeclampsia in high risk pregnant women without thrombophilia. SEARCH STRATEGY: PubMed, Embase and the Cochrane library were searched for articles published before 1st August 2022 using the combination keywords "preeclampsia", "Low Molecular Weight Heparin", "LMWH", "Heparin, Low Molecular Weight", "Dalteparin", "Nadroparin", and "Tinzaparin". SELECTION CRITERIA: Randomized controlled trials evaluating the use of LMWH in pregnant women at high risk of preeclampsia without thrombophilia...

Data to guide evidence-based management of pregnant people with sickle cell disease (SCD) is limited. This international Delphi panel aimed to identify consensus among multidisciplinary experts for SCD management during pregnancy. The two-round Delphi process used questionnaires exploring seven topics (antenatal care, hydroxyurea use, transfusion, prevention of complications, treatment of complications, delivery and follow-up, and bottlenecks and knowledge gaps) developed by a steering committee. Thirteen panelists (hematologists, physiologists, obstetricians, maternal fetal medicine and transfusion medicine physicians) from the US, the UK, Turkey and France completed the first survey; 12 panelists completed the second round...

BACKGROUND: Recent studies showed that aspirin for preeclampsia prevention is underused despite its effectiveness in preventing preeclampsia among patients with moderate and high risk factors. Little is known about this issue in the Sub-Saharan setting, including Ethiopia. OBJECTIVE: This study aimed to determine the missed opportunity for aspirin prophylaxis among candidates for this preeclampsia preventive intervention at a national tertiary referral hospital in Ethiopia...

BACKGROUND: Tacrolimus is one of the major treatment options for systemic lupus erythematosus (SLE) and is considered to be a pregnancy-compatible medication. Since little is known about tacrolimus safety during pregnancy complicated by SLE, this study was designed. METHODS: We included SLE pregnant patients who were followed up at two Japanese tertiary referral centers. We performed multivariate logistic regression analysis to assess each adverse pregnancy outcome (APO) risk...

BACKGROUND: Preeclampsia is a life-threatening disease of pregnancy that lacks effective pharmaceuticals which can target its pathogenesis. Since preeclampsia involves complex pathological processes, including autophagy, this study aims to explore autophagy-related mechanisms of preeclampsia and to screen potential drugs. METHODS: Firstly, the datasets GSE75010, GSE24129, GSE66273, and autophagic genes lists were downloaded from public databases. Then, a weighted gene co-expression network analysis (WGCNA) was applied to filter autophagic-related hub genes of preeclampsia...

BACKGROUND: The exact mechanism by which aspirin prevents preeclampsia remains unclear. Its effects on serum placental biomarkers throughout pregnancy are also unknown. OBJECTIVE: To investigate the effects of aspirin on serum pregnancy-associated plasma protein A and placental growth factor trajectories using repeated measures from women at increased risk of preterm preeclampsia. STUDY DESIGN: This was a longitudinal secondary analysis of the Combined Multimarker Screening and Randomized Patient Treatment with Aspirin for Evidence-based Preeclampsia Prevention trial using repeated measures of pregnancy-associated plasma protein A and placental growth factor...

OBJECTIVE: We sought to describe the pharmacokinetics and pharmacodynamics of aspirin through pregnancy (first and third trimester), to identify covariates that significantly impact aspirin pharmacokinetics (PK) and to identify the relationship between aspirin pharmacokinetics and pharmacodynamics (PD). STUDY DESIGN: This is a prospective study of patients at high risk for preeclampsia recommended to take 81mg aspirin daily. This study involved three visits: baseline: 1st trimester (10-16' weeks) 6-hour PK visit, done prior to initiation of aspirin; follow up-1: 2-4 weeks after aspirin initiation; Follow up-2: 3rd trimester 6-hour PK visit (28-32 weeks')...

Thrombocytes play an essential role in hemostasis and thrombosis. Moreover, the controlled activation of thrombocytes is required in reproduction and fertility. The platelet-activating factor and the controlled activation of platelets have important roles in folliculogenesis, ovulation, placental development, implantation and embryo development. Activated platelets accumulate in the follicular vessels surrounding the follicle and, due to its released soluble molecules (factors, mediators, chemokines, cytokines, neurotransmitters), locally increase oocyte maturation and hormone secretion...

OBJECTIVE:  To evaluate the feasibility and impact of using the first-trimester ultrasound visit to identify and counsel women at increased risk of preeclampsia about the benefits of low-dose aspirin (LDA) for preventing preeclampsia. We also assessed patient-reported utilization of LDA, perceived risk for preeclampsia, and clinical outcomes. STUDY DESIGN:  Women presenting for routine first-trimester nuchal-translucency (NT) ultrasounds were screened for clinical preeclampsia risks using a self-administered risk assessment...

Preeclampsia is a major cause of maternal and perinatal morbidity and mortality. It is important to identify women who are at high risk of developing this disorder in their first trimester of pregnancy to allow timely therapeutic intervention. The use of low-dose aspirin initiated before 16 weeks of gestation can significantly reduce the rate of preterm preeclampsia by 62 %. Effective screening recommended by the Fetal Medicine Foundation (FMF) consists of a combination of maternal risk factors, mean arterial pressure, uterine artery pulsatility index (UtA-PI) and placental growth factor (PLGF)...

OBJECTIVE: Interventions aimed at preventing disease are commonly studied as strategies of primary or secondary prevention. Unfortunately, this dichotomy can be misleading, and studies might unknowingly exclude people at high risk of the disease that could benefit from the intervention. Here I use the example of aspirin for prevention of preeclampsia to illustrate this problem. METHODS: I use directed acyclic graphs to represent several causal models of aspirin and preeclampsia, each making different assumptions regarding the causal relation between previous preeclampsia, aspirin, and subsequent preeclampsia...

BACKGROUND: Preterm birth is a leading cause of perinatal morbidity and mortality. There are significant racial disparities in the rates of preterm delivery in the United States, with Black individuals at disproportionately higher risk than their White counterparts. Although low-dose aspirin is currently under investigation for reducing the rates of preterm delivery, limited data are available on how the use of low-dose aspirin might affect racial and ethnic disparities in the rates of preterm delivery...

Systemic lupus erythematosus (SLE), a multiorgan systemic inflammatory disorder, predominantly affects women during their reproductive years. In this review, we summarize the state of knowledge about preconception planning and management of SLE during pregnancy. Achieving remission or low disease activity for several months on medications compatible with pregnancy prior to conception is essential to decreasing the risk of disease flare and improving pregnancy outcomes, including pre-eclampsia, preterm birth, and intrauterine growth restriction...

PURPOSE OF REVIEW: To review recent data describing the challenges and innovations in therapeutic research focused on the prevention and treatment of preeclampsia. RECENT FINDINGS: Pregnant individuals have traditionally been excluded from therapeutic research, resulting in a paucity of innovation in therapeutics for pregnancy-specific medical conditions, especially preeclampsia. With the increased awareness of maternal morbidity and mortality, there is significant interest among researchers to expand therapeutic research in pregnancy...

Preeclampsia is associated with significant perinatal morbidity and mortality. Aspirin has been long purported and extensively studied for prevention of preeclampsia. For this reason, the U.S. Preventive Services Task Force, the American College of Obstetricians and Gynecologists, and the Society for Maternal-Fetal Medicine recommend its use in pregnancy for preeclampsia prevention in those at high risk. Yet, much controversy exists regarding optimal use in pregnancy with guidelines across global organizations varying...

BACKGROUND: Preeclampsia, a condition in pregnancy characterized by new onset high blood pressure and proteinuria, complicates 2%-8% of pregnancies globally. Early detection, careful monitoring, and treatment of high blood pressure are crucial in preventing mortality related to preeclampsia disorders. There is limited data that examines obstetric/gynecologic (OBGYN) provider-type practices concerning management of hypertensive disorders of pregnancy to reduce early onset preeclampsia (EOP)...

OBJECTIVE: To identify strategies to reduce maternal and neonatal morbidity related to preeclampsia. MATERIAL AND METHODS: The quality of evidence of the literature was assessed following the GRADE® method with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases...

Recurrent miscarriage is defined as more than three pregnancy failures occurring before 20 weeks of gestation. Poor differentiation of the endometrial stroma or defective trophoblast cell invasion at the maternal-fetal interface leads to recurrent miscarriages. Several miRNAs, including miR-20b-5p, are aberrantly regulated in recurrent miscarriages; however, the underlying molecular mechanisms remain unclear. Primary cilia are antenna-like organelles that coordinate signaling during development and differentiation...
