Comparative Study of Tranexamic Acid Dosing in Cardiac Surgery
Tranexamic axid is routinely used as an antifibrinolytic agent in cardiac surgery to reduce the risk of blood loss and transfusion. However, there is no consensus regarding the dosage regimen of tranexamic acid that should be administered. The purpose of this study is to compare different dosages of tranexamic acid …
Hemophilia A Research Program
This study longitudinally observes the intergenerational (mother-child) continuum in hemophilia A from pregnancy through early childhood. Because the study follows mother-child pairs, the study includes both a maternal cohort and a pediatric cohort. Each cohort has a primary goal: for the mother with a severe hemophilia genotype, the overarching primary …
Embolization in Hereditary Coagulopathies
This is a longitudinal, prospective study, which will include 30 subjects with hereditary coagulopathies, with arthropathy, chronic synovitis resulting from hemarthrosis of the elbows, knees and/or ankles followed up at the Centro de Hemofilia HCFMUSP, after approval by the ethics and research committee. They will undergo imaging tests (X-rays and …
Liver and Coagulation Disorders in Cardiac Transthyretin Amyloidosis
Transthyretin cardiac amyloidosis (ATTR-CA) is a progressive infiltrative cardiomyopathy caused by the deposition of misfolded transthyretin protein within the myocardium. Current disease staging and follow-up strategies mainly rely on cardiac biomarkers and renal function; however, the systemic nature of ATTR suggests that additional organ involvement may provide valuable prognostic information. …
Coagulopathy of Immunodermatologic Diseases
This study will examine the coagulation and fibrinolysis profiles of those with autoimmune skin diseases. Blood samples will be collected from participants with active/poorly controlled immune-mediated skin diseases and mild/latent/well-controlled immune-mediated skin diseases. A one-time sample from 15 general dermatology outpatients who do not have a known or suspected diagnosis …
COVID-19 Coagulopathy Extension Study
At the University of Iowa, the investigators led a multicenter randomized clinical trial comparing standard prophylactic dose to intermediate dose enoxaparin in hospitalized patients with COVID-19 (NCT04360824). As part of an exploratory biomarker component of this trial, blood samples were collected from hospitalized COVID-19 patients at enrollment and weekly for …
Bleeding Disorder of Unknown Cause in the Netherlands
The purpose of the Bleeding Disorder of Unknown Cause in the Netherlands study (BDUC-iN) is to learn more about unexplained bleeding in individuals with a bleeding disorder of unknown cause (BDUC). The study aims to better understand why these individuals have increased bleeding and how it affects their health and …
International Registry of Dengue Infection in Congenital Bleeding Disorders (DengueCBDR)
Dengue fever, a viral infection transmitted by Aedes mosquitoes, is a major health issue in tropical and subtropical regions. Around 20-30% of symptomatic patients developed Dengue Hemorrhagic Fever (DHF), which leads to impaired hemostasis, subsequently increasing the risk of bleeding. The hemostatic abnormalities associated with dengue infection included vascular permeability, …
Blood Clotting Markers and Heart Ultrasound in People With Device-Detected Atrial Fibrillation
The purpose of this observational study is to investigate whether blood tests related to blood clotting are associated with established clinical stroke risk scores, the total amount of device-detected atrial fibrillation recorded by an implanted cardiac device, and ultrasound measurements of the heart in people with device-detected atrial fibrillation. The …
A Study to Learn About How Safe BAY3389934 is and How it Affects Blood Clotting When Given Alone or With Aspirin in Healthy Participants
The study treatment BAY3389934 is under development for people with blood clotting problems that occur due to sepsis. Sepsis is a serious condition that happens when the body's reaction to an infection causes organ damage. It can eventually lead to tiny blood clots formation throughout the body. BAY3389934 aims to …
