Filter by:Adult patients on extracoporeal membrane oxygenation (ECMO) frequently experience bleeding, which is in part caused by acquired von Willebrand syndrome (vWS). Prior in vitro studies have shown that the addition of recombinant von Willebrand Factor (vWF) to ECMO patient blood samples, normalizes platelet adhesion and thrombus formation. This study is a phase I study, where adult ECMO patients with refractory bleeding will be treated with recombinant vWF a single time. The primary objectives are to evaluate the safety, tolerability, and pharmacokinetics of recombinant vWF in adult ECMO patients.
The objective of this study was to evaluate the therapeutic effect of nafamostat mesilate on patients with severe infection-related coagulation。
The goal of this prospective cohort study is to examine circulating biomarkers before and after weight loss in patients with obesity, with or without concomitant diabetes, undergoing bariatric surgery. The main questions that are being addressed are: - Do biomarkers of hemostasis, including coagulation, fibrinolysis, and platelet function improve following surgery and if so, is that improvement more pronounced in patients with diabetes? - Do biomarkers of endothelial function and other aspects of vascular function improve following surgery and if so, is that improvement more pronounced in patients with diabetes? - Do biomarkers of inflammation, including markers of adipocyte function, improve following surgery and if so, is that improvement more pronounced in patients with diabetes? - The possible role of circulating extracellular vesicles reflecting biological functions above will also be investigated (optional) Participants will be asked to attend in total five study visits before and after surgery including a final visit at two years post-surgery. Comparisons will be performed within- as well as between groups.
INTRODUCTION Knee supports, usually made with sponge cushion, are used to protect knee joint and prevent its injury. Sponge has less elasticity and durability compared with natural rubber. To our knowledge, there has been no study regarding effectiveness of natural rubber and sponge for knee joint protection and injury prevention in children with bleeding disorders. AIMS The study aimed to compare the effectiveness and satisfaction between natural rubber and sponge knee supports for knee joint protection among children with bleeding disorders METHODS The study had three phases: 1) measurement of compression force, 2) fabrication of knee supports, and 3) a randomized crossover trial. The supports were fabricated in 4 sizes, S, M, L, and XL. They comprised two parts: body, made from stretchable cotton; and cushion (protection part), made from either natural rubber or sponge. The trial included 8 weeks of alternatively wearing natural rubber knee support and sponge knee support with a 4-week wash-out period. Numbers of knee bleeds and satisfied users were recorded.
This is a single center prospective observational study to compare QStat parameter measurements in arterial and venous blood samples collected in parallel from patients undergoing liver transplantation.
This is a Phase 1a, double-blind, randomized, placebo- controlled, SAD study to assess safety, tolerability, PK, and PD of TU7710 in warfarin treated healthy male participants.
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 overall goal of this study is to evaluate the effectiveness of a previously developed storytelling intervention on anticoagulation (AC) initiation/persistence in African American and Black patients with atrial fibrillation/flutter. The investigators hope to gain knowledge that may help treat atrial fibrillation or flutter and lower stroke and adverse cardiovascular event risks for African American and Black patients by increasing the use of blood thinning medications known as anticoagulants.
This study aims to find out if there are common major changes in coagulation immediately after delivery of the newborn during Cesarean (C) -section and vaginal birth.
In this study the investigators will assess both procoagulant and anticoagulant pathways using thrombin generation and platelet function tests; as well as neuronal ischemia using cell free DNA in all patients presenting with ischaemic and haemorrhagic stroke (including aneurysmal subarachnoid haemorraghe). Also the cross-talk between inflammation and thrombosis, so-called thrombo-inflammation is further investigated. As such the investigators aim to characterise the patient's coagulation profile before administration of any treatment. By assessing these pathways the investigators strive to detect specific markers to predict vital and functional outcome at 3 months in these patients. Finally the investigators may provide new pathophysiological insights in the course of disease following these events that can possibly improve future therapeutic strategies.
