Filter by:Comparison of capillary whole blood INR determined by LumiraDx Instrument to venous plasma INR determined by laboratory reference method (IL ACL ELITE PRO) for method comparison and assessment of accuracy and bias by regression analysis and other analytical methods.
This study is to evaluate the effect of sarpogrelate on blood viscosity after 24 weeks in patients with high blood viscosity.
Recurrent pregnancy loss (RPL) is a clinical problem affecting 1-5% of couples of reproductive age. The contribution of thrombophilia to RPL is disputed. This controversy is partly due to low sensitivity of the genetic variants currently used to evaluate hereditary thrombophilia: the Leiden mutation (identified as rs6025) in the coagulation factor 5 (F5L) gene and mutation G20210A (identified as rs1799963) in the prothrombin (PT) gene. Our objective was to determine whether a wider algorithm that includes clinic and genetic variants associated with thrombophilia could be more useful in the prediction for RPL than FVL and PT alone.
The purpose is to determine the hypercoagulable phenotype by thrombinography associated to an increased risk of symptomatic and objectively confirmed first venous thrombotic event. This is a case-control study in a population with patients having systemic lupus erythematosus (SLE) and/or antiphospholipid antibodies (APL). Secondary purposes are: 1. To determine the frequency of hypercoagulable phenotype in study population; 2. To analyze the sensibility: consequences of variation of hypercoagulable phenotype threshold on the importance of risk; 3. To identify (genetic and not) factors for hypercoagulable phenotype and their frequency in different groups.
Patients with myeloproliferative neoplasms Philadelphia chromosome negative (MPNsPh1-) such as Essential thrombocytosis (ET), Polycythemia vera (PV) and Primary Myelofibrosis (PMF) have a higher risk of arterial or deep-vein thrombosis. This is responsible for a significant increase in mortality (up to 31% of increase in thrombosis risk in ET). Cellular inflation and blood hyperviscosity, resulting from these diseases, fail to account for these thromboses, as more than 50% of thrombotic complications happen under adapted antineoplastic drug treatment. These last years, cellular microparticles (MPs) have been shown to play a major role in thrombogenesis. MPs are generated by apoptosis or the activation of malignant cells, platelets, endothelial cells or monocytes. They are fragments of plasma membrane, smaller than 1 µm, rich in phosphatidylserine, which can express the tissue factor and serve as support for the coagulation factors. Increase in the plasma concentration of procoagulant platelet microparticles has been demonstrated in other thrombotic diseases (acute coronary syndrome, disseminated intravascular coagulation DIC, etc.). The working hypothesis is that platelet microparticles are involved in the hypercoagulability of MPNs patients.
The primary objective of this study was to evaluate and compare the prevalence of the following psychiatric pathologies (based on the MINI5.0.0 questionnaire) among 3 groups of women (Leiden versus aP1Ab-positive versus thrombophilia-negative) with similar obstetrical histories 10 years after their initial assessment/diagnosis. - Mood disorders, including depressive episodes during the previous two weeks, recurrent depressive disorders at any point in life, dysthymia in the last two years, or any current or past manic episode; - Anxiety disorders, including current agoraphobia, current panic disorders, agoraphobia with panic disorders, current social phobia, generalized anxiety in the last 6 months, or current posttraumatic stress syndrome; - Apparent psychotic syndromes, including isolated or recurrent psychotic syndromes, past or present (clinically validated), - Current alcohol or drug problems (dependence or abuse).
Investigators hypothesized that the impact of surgery in terms of inducing a hypercoagulable state is more evident in morbidly obese pregnant women as opposed to their non-obese counterparts. The aim of this study is to investigate the change in coagulation status of morbidly obese and non-obese pregnant women following cesarean section delivery using thromboelastometry. This observational study would also make it possible to calculate the sample size for a future prospective controlled clinical trial to compare the incidence of Hypercoagulability in morbidly obese parturients as opposed to their non-obese counterparts. To the best of our knowledge, no other work has been done any in this area.
Hospitalization in pregnancy and childbirth greatly increases the thromboembolic risk of these patients. The application of a protocol for assessing the risk of VTE reduces mortality and morbidity of these phenomena.
Both hereditary and acquired thrombophilia have been associated with recurrent miscarriage and pregnancy complications. Thrombophilia could favor the development of thrombosis of the maternal vasculature and obstacle placentation. Some studies have suggested a role of thrombophilia in the failure of assisted reproductive techniques although this association has been recently questioned. The scope of this study is to evaluate the effect of thrombophilia on the implantation rate and live birth rate in women undergoing ART. Design: prospective, observational study Primary end-point: live birth rate. Secondary end-points: implantation rate, venous thromboembolic events during ART up to 6 weeks post-partum
In total 120 pregnant women's with history of recurrent miscarriages, are planned for inclusion in this trial. After signing an informed consent a blood sample will be obtained from each participant. The investigators will measure the thrombin generation in plasma assessed by the calibrated automated thrombogram (CAT). The relation between pregnancy outcome and thrombin measurements will be determined
