Filter by:Novel coronavirus disease 19 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), this pneumonia was first emerged in December 2019 in Wuhan, China and rapidly spread around the world . Coagulopathy is one of the most significant prognostic factors in patients with COVID-19 and is associated with increased mortality and admission to critical care. Most observed coagulopathy in patients hospitalized with COVID-19 (COVID-19-associated coagulopathy) is characterized by increased D-dimer and fibrinogen levels. 71% of patients who did not survive hospitalization reported to have developed disseminated intravascular coagulation
This study will study the potential utility of the Quantra QPlus System in patients inflicted with COVID-19 disease.
The purpose of this study was to identify the relationship between coagulopathy during the perioperative period (before the operation and on the first day after the operation) and the long-term survival of traumatic brain injury patients undergoing surgery, as well as to explore the predisposing risk factors that may cause perioperative coagulopathy.
Hemostasis-related disorders are common in cirrhosis and portal hypertension. However, it is not known whether the net effect of changes in hemostasis in the sense of predisposition to hemorrhagic or thrombotic state. It is suggested that increasing the concentration and activities of Von Willebrand factor (vWF) and decline ADAMTS-13 (A Disintegrin and Metalloproteinase with Trombospondin type 1 motif, member 13) may cause thrombophilic changes in cirrhosis and portal hypertension. The aim of this study was to investigate the changes in ADAMTS-13 (A disintegrin and metalloproteinase with thrombospondin motifs 13) and von willebrand factor (vWF) levels and activities in patients with cirrhosis and portal hypertension.
Our study included both in- and outpatients suffering from liver cirrhosis attending the out- and inpatient care of the department of hepatology. Demographic and biochemical data as well as medical history including cause of liver cirrhosis, end stage kidney failure and medication with anticoagulants were recorded. To assess the hemostatic profile, platelet function was analyzed by multiple electrode aggregometry (MEA) using Multiplate (ADP-, ASPI- and TRAP-test) and thrombelastometry using ROTEM (EXTEM, INTEM, FIBTEM).
The objective is to determine the reference range intervals for the parameters reported by the Quantra System with the QStat Cartridge.
This study includes patients undergoing elective cardiac surgery on MiECC. Coagulation status is assessed with ROTEM (TEM International GmbH, Munich, Germany) and Platelet function with impedance aggregometry using the ROTEM-Platelet (TEM International GmbH, Munich, Germany).
Cytoreductive surgery (CRC) with intraperitoneal hyperthermal chemotherapy (HIPEC) has been shown to improve survival in selected patients with peritoneal carcinomatosis. 51% of patients are transfused due to the high intraoperative blood loss caused by surgery and the appearance of a perioperative coagulopathy attributed to the loss of proteins into the peritoneal cavity, the high fluid turnover and possibly the action of hyperthermic chemotherapy. So far, the haemostatic changes described consist of a decrease in the levels of antithrombin III and the platelet count, as well as in alterations of the usual coagulation tests. Conventional coagulation tests analyze only the plasmatic phase of coagulation while viscoelastic tests, such as rotational thromboelastometry (ROTEM), reproduce the global coagulation process much more faithfully, keeping good correlation with perioperative bleeding. Objetive: The platelet, coagulation, von Willebrand and Factor XIII levels and function have not been consistently investigate in pre-established (fix) time periods in patients undergoing elective CRC with hyperthermia. This prospective observational study aimed at investigating the variations of the values of estándar coagulation test, ROTEM parameters, platelet function assay (PFA-100), von Willebrand and Factor XIII at baseline (before surgery) and after 4h and 48 after surgery in 40 patients undergoing CRC. A control group (N=40 blood donors) will be also obtained by baseline comparasion and to obtain local reference ranges.
The overall incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) is 1 per 200 cancer patients, about 5 times higher than in the general population. These events are of crucial importance, since nearly 10% of cancer patients died from thromboembolic events (EVT), making them the second leading cause of death in this population. In hospitalized patients, the rate seems to have increase between 1979 and 1990 from 0.6% - 2% before 1990 to 4% since 1990. Thrombotic risk in cancer patients is known and identified. Thrombotic complications affect the survival and quality of life of cancer patients. Chemotherapy is a regular generator of cytopenia, the most prominent of which is thrombocytopenia. In addition, a prospective study of 107 cancer patients in our institution shows that almost 40% of patients over 65 years of age take anticoagulant or antiplatelet therapy. In this specific population (i.e., with cancer and hypocoagulability), the occurrence of thrombosis poses particular problems. The prevalence and incidence of venous thrombosis in this situation is unknown and the behavior to be poorly specified. Based on these considerations, The investigator propose a two-year prospective cohort study to explore the biological parameters of hypocoagulability and to assess the incidence and prevalence of DVT in thrombocytopenic patients on vitamin K antagonists. (AVK), anti-platelet aggregation (AGP) and / or direct oral anticoagulant (AOD). In this study, the investigator means by hypocoagulability any situation modifying the normal coagulation system.
The XIENCE 28 USA Study is prospective, single arm, multi-center, open label, non-randomized trial to evaluate safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS and XIENCE Sierra EECSS) of coronary drug-eluting stents.
