Active clinical trials for "Blood Coagulation Disorders"

The goal of this observational study is to learn if acutely and/or chronically altered sleep induces inflammation and/or a pro-thrombotic state (a tendency to form clots) in hospital workers who either work in shifts or are exclusively daily workers. The main questions it aims to answer are: Does chronically altered sleep induce a pro-inflammatory and pro-thrombotic state, which are steps towards cardiovascular disease, knowing that is associated with poor sleep? Does acutely disrupted sleep, such as that observed in night shift workers, induce a pro-inflammatory and pro-thrombotic state in otherwise healthy subjects? Participants in the study are hospital workers who either work in shifts, including night shifts, or only during the day. Sleep quality is assessed by a validated questionnaire (the Pittsburgh Sleep Quality Index). Markers of inflammation and of the pro-thrombotic state are measured at baseline and, if appropriate, after the night shift. These are markers of platelet activation, D-dimer, Interleukin-6 and endothelin 1, known to contribute and/or to suggest a condition of generalized inflammation and a tendency to form clots. Relevant information on health status is also collected for each participant.

The Swiss Hemophilia Registry will collect data on the prophylactic and therapeutic use of factor concentrates in patients with hemophilia and other severe bleeding disorders in Switzerland.

With the help of a standardized questionnaire, an increased risk of bleeding due to pre-existing hemostasis disorders in the site-specific patient population will be detected and the corresponding enhanced diagnostic measures will be initiated. The planned prospective observational study should i.) systematically investigate the results of this procedure and ii.) allow a comparison with a retrospective perioperative cohort that was cared for at the Benjamin Franklin Campus before the introduction of the questionnaire. Due to the campus structure with a large vascular surgery center as well as a large urological, general and trauma surgery department, a high number of multimorbid patients with pre-existing disorders of primary hemostasis, mainly caused by medication or secondary diseases, is to be expected. In the following, the feasibility of the required measures in clinical routine (measured by the frequency of actual changes or modifications of the initially planned perioperative procedure, the adequate implementation of indicated diagnostic measures, etc.) will be examined.

This is a prospective, single-center, controlled, open label, trial randomized in two parallel groups designed to assess the Quantra QStat System in trauma patients.

The study was a retrospective, single-center clinical study. From all patients admitted to the emergency ICU during the period of 2013.1.1-2019.12.31, the investigators screened all patients who met the criteria of 1) ≤7 days from symptom onset to enrollment; 2) patients who also met the criteria of the presence of clinical infections and Sequential Organ Failure Assessment (SOFA) score ≥2; and 3) met the exclusion criteria, and retrospectively collected coagulation indices of the patients before anticoagulation with or without the use of heparin or low molecular heparin, and recorded the worst values of coagulation function of patients before heparin were recorded, and the organ function, inflammatory response, immune indexes, and conversion rate of severe disease were observed, so as to investigate the role of conventional coagulation indexes (FDP, D-dimer) and thromboelastography in the early diagnosis of septicemia patients and to indicate the prognosis.

The existence of AAS coagulopathy has been reported, related to blood contact with the walls of the non-endothelialized false lumens. It is likely that endothelial dysfunction generated by vascular lesions may largely contribute to the development of coagulopathy, such as described in trauma-induced coagulopathy. This endotheliopathy of the AAS has never been evaluated. The coagulopathy of AAS and more specifically the endotheliopathy are poorly described and therefore have no standardized treatment. The main objective of this study is to describe the coagulopathy

The G-NUH registry is a two-center, real-world registry of percutaneous coronary intervention in patients with significant coronary artery disease. From January 2010, PCI-treated patients from Gyeonsang National University Hospitals (Jinju & Changwon) were enrolled in this registry. The aim of this registry is to investigate long-term clinical outcomes and predictors of adverse outcomes after percutaneous coronary intervention from the academic hospitals.

The purpose of the study is to describe the differences in measurements of viscoelastic tests of coagulation by two different devices in adult trauma patients.

Background Hematological diseases are disorders of the blood and hematopoietic organs. The current hematological cohorts are mostly based on single-center or multi-center cases, or cohorts with limited sample size in China. There is a lack of comprehensive and large-scale prospective cohort studies in hematology. The purpose of this study is to analyze the incidence and risk factors of major blood diseases, the treatment methods, prognosis and medical expenses of these patients in China. Method The study will include patients diagnosed with acute myeloid leukemia, multiple myeloma, hemophilia, aplastic anemia, leukemia, myelodysplastic syndrome, lymphoma, bleeding disorders or received bone marrow transplantation in the investigating hospitals from January 1, 2020, and collect basic information, diagnostic and treatment information, as well as medical expense information from medical records. In its current form, the NICHE registry incorporates historical data (collected from 2000) and is systematically collecting prospective data in two phases with broadening reach. The study will use questionnaire to measure the exposure of patients, and prospectively follow-up to collect the prognosis information.

Coagulopathy, bleeding, and transfusion are common in cardiac surgical patients. Our collaborator has developed a novel point of care device that can be used to assess thrombin generation in real-time in cardiac surgical patients. The investigators will measure thrombin generation using our novel device and compare it to standard methods, while examining the association of thrombin parameters with bleeding and other clinical outcomes.
