Filter by:Protamine is routinely used as a heparin reversal agent in cardiac surgery. However, its use may be associated with adverse events, while protamine excess may have additional anti-coagulant affect. Although guidelines advise towards a diminished reversal ratio, clinical practice remain heterogenic. The purpose of this study is to compare two different reversal ratios (0.6:1 και 0.8:1) of total heparin regarding the Activated Clotting Time (ACT), viscoelastic assays (Clot-Pro) and clinical hemorrhage. A baseline ACT value and Clot Pro tests will be obtained prior to the operation start. After the initial reversal, ACT, Clot Pro tests will be conducted again. Coagulation factors are administrated according to Clot Pro results, and in case of ongoing clinical hemorrhage and any indication of heparin excess in the measured values, another 25mg of protamine is administrated, while tests are repeated.
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.
A cross-sectional study will be conducted, which will include 80 young patients with psoriasis, aged 30-45 years, treated with five different types of antipsoriatic treatment, and 20 healthy patients. All 100 subjects will be subjected to anthropometric measurements, blood will be collected for laboratory tests, and an imaging test will be performed to determine the function of the endothelium and arterial stiffness. The results will then be statistically analyzed.
Liver resection is the treatment of choice in patients with primary or metastatic liver neoplasms, benign liver neoplasms and numerous biliary diseases. In these patients, in the postoperative period,several factors can induce a transient alteration of the synthesis hepatic coagulation factors such as size of the lesion liver, underlying liver disease (e.g. malignancy), pre-existing cirrhosis, duration of both surgery and vascular clamping, and blood loss. So far, some studies have shown that conventional coagulation tests indicate a hypocoagulable state which may lead to excessive transfusions of blood products or an increased risk of thromboembolic events related to delayed initiation of thromboprophylaxis in the postoperative period. In an attempt to optimizing the state of coagulation, recently there is increased interest for viscoelastic coagulation testing (thromboelastography and rotational thromboelastometry). The results of these studies have shown that these patients often have a hypercoagulable and non hypocoagulable profile as evidenced by conventional coagulation tests. the purpose of the study is to evaluate whether the combination of coagulation tests conventional systems and new thromboelastography can increase the quality of surveillance of the coagulation state after liver surgery, in order to optimize the management of postoperative blood coagulation of these patients.
Objective of this study was to determine the relationship between CAC and septic condition in COVID-19 critically ill patients. Data including age, sex, comorbidities, quick Sequential Organ Failure Assessment (qSOFA) score, vasopressors requirement, laboratory findings: platelets, neutrophils, lymphocytes, procalcitonin (PCT), C-reactive protein (CRP), fibrinogen, D-dimer, sepsis-induced coagulopathy (SIC) and disseminated intravascular coagulation (DIC) score were recorded on the day of admission and on the day of starting of invasive mechanical ventilation. Primary outcome was to establish CAC with sepsis; secondary outcome measure was incidence of CAC in sepsis and septic shock in COVID-19 critically ill patients.
Chamomile may possess anticoagulant effects based on the presence of coumarin-like compounds within the flower. This randomized complete crossover study will investigate the impact of chamomile ingestion acutely on coagulation.
The main objective was to demonstrate the existence and importance of hypercoagulability in patients with IBD, by determining the prevalence of changes in coagulation parameters and evaluating the impact of these changes on the occurrence of thromboembolic events.
A single centre, double-blind, randomized, parallel group, placebo-controlled study in healthy subjects conducted in two parts: Part 1: Single ascending doses in healthy subjects aged 18 to 49 years to assess safety, pharmacokinetics (PK) and pharmacodynamic (PD) effects of VMX-C001. Part 2: Healthy subjects aged 50 to 79 years to assess safety, PK and PD effects of VMX-C001 in the presence of DOACs.
The damage of the endothelial glycocalyx is based on microvascular endothelial dysfunction and typical for critical clinical conditions like sepsis, trauma, bleeding, shock, as well as ARDS. We aim to generate first hints regarding the impact of covid-19 disease on the (damage) of the endothelial glycocalyx. Furthermore, we want to investigate the potential coagulopathies, which go along with shedding of the glycocalyx. The detection of and the relation between the severity of the disease, as well as the extent of the glycocalyx damage during the observational period, as well as the hemostatic alterations, are aim of the study.
