Introduction. Thromboelastography (TEG) is a dynamic assessment tool used to assess hemostasis with decompensated chronic liver disease (DCLD). Conventional coagulation tests, such as prothrombin time (PT), international normalized ratio (INR), and activated partial thromboplastin time (aPTT), may not fully reflect the complexity of coagulation abnormalities in these patients. This study investigates the correlation between TEG parameters, conventional coagulation tests, and platelet count in patients with and without clinical bleeding manifestations. Material and methods.

We aimed to examine hypercoagulable and hypocoagulable conditions in patients with prostate cancer using thromboelastography (TEG) and correlate TEG parameters with conventional coagulation test. The t test was used for comparing TEG parameters and routine coagulation results. Spearman rank-order correlation was used to describe the relationship of TEG and conventional tests. Sensitivity, specificity, positive predictive values, and negative predictive values were determined for bleeding and thrombosis. Totally, 20 patients had active bleeding postoperatively, 16 of whom showed hypocoagulation

Our objective was to describe the relationship between TEG and conventional coagulation tests (CCTs), which has not been previously explored in this population. Methods: In acutely ill patients with severe CLD (Child-Pugh score > 9, category C), we conducted a prospective observational study investigating coagulation assessment as measured by both CCTs and TEG.

Coagulation and transfusion management in patients undergoing liver transplantation is challenging. Proper perioperative monitoring of hemostasis is essential to predict the risk of bleeding during surgery, to detect potential causes of hemorrhage in time, and to guide hemostatic therapy. The value of conventional coagulation test is questionable in the acute perioperative setting due to their long turnaround time and the inability to adequately reflect the complex changes in hemostasis in patients with liver disease.

Cancer and cancer therapy can interfere with coagulation physiology and lead to a myriad of clinical presentations, which need prompt but comprehensive evaluation and management. The clinical spectrum of coagulation abnormalities ranges from thrombotic complications such as venous thromboembolism and arterial micro-thrombi to haemorrhagic complications, including disseminated intravascular coagulation. The risk of developing venous thrombosis is highest in the first year following cancer diagnosis. Coagulation abnormalities are frequently encountered in the peri-operative period, as well as in

The blood coagulation test is an indispensable test for monitoring the blood coagulation and fibrinolysis functions. Currently, activated partial thromboplastin time (APTT) is the most widely used approach to coagulation testing. However, APTT reagents need to be optimized due to the fact that they are unstable, highly variable, and cannot be easily controlled. In this study, we created apoptotic cell-inspired methacryloyloxyethyl phosphorylserine (MPS) particles for blood coagulation as an alternative to conventional APTT reagents.

AbstractHemostasis is a dynamic age-related process, which gradually evolves from fetal life throughout childhood until adulthood. Although at birth there is a hemostatic deficit of most coagulation factors, studies have shown that this “hemostatic immaturity” is functionally counterbalanced in healthy term or preterm newborns. This delicate hemostatic balance is, however, deranged in sick neonates, resulting in an enhanced risk of hemorrhage and/or thrombosis. In critically ill neonates, conventional coagulation tests do not seem to provide reliable information or indications regarding the fu

Aims, Objectives and BackgroundPatients who have sustained a traumatic brain injury (TBI) can have disturbances in coagulation that are distinct from other traumatic bleeding states.1 Coagulopathy is a risk factor for exacerbation of the primary injury, and these patients have less favourable outcomes and increased mortality compared to non-coagulopathic patients.1 Little is known about the longitudinal coagulation changes following TBI.The aim of this pilot study was to investigate the coagulation profiles of patients presenting with severe TBI over the first 7 days following injury.Method an

Extracorporeal membrane oxygenation (ECMO) is used for the management of severe respiratory and cardiac failure and as a bridge to achieve definite treatment or transplantation. ECMO-associated coagulopathy (EAC) is a frequent complication leading to high rates of thrombosis or severe haemorrhage, contributing to morbidity and mortality among patients. Understanding the pathophysiology of EAC is substantial for effectively managing patients on ECMO. We analyse the underlying mechanism of EAC and discuss the monitoring of the coagulation profile, combining the viscoelastic point-of-care assays

Background: The treatment of COVID-19 patients with heparin is not always effective in preventing thrombotic complications, but can also be associated with bleeding complications, suggesting a balanced approach to anticoagulation is needed. A prior pilot study supported that thromboelastography and conventional coagulation tests could predict hemorrhage in COVID-19 in patients treated with unfractionated heparin or enoxaparin, but did not evaluate the risk of thrombosis. Methods: This single-center, retrospective study included 79 severely ill COVID-19 patients anticoagulated with intermediate

The monitoring of coagulation by viscoelastometric methods—thromboelastography and rotational thromboelastometry—may detect the contributions of cellular and plasma components of hemostasis. These methods might overcome some of the serious limitations of conventional laboratory tests. Viscoelastic testing can be repeatedly performed during and after surgery and thus provides a dynamic picture of the coagulation process during these periods. Several experiences with the use of these methods in cardiovascular surgery have been reported, but there is perspective for more frequent use of these ass

Abstract Liver disease results in complex alterations of all 3 phases of hemostasis. It is now recognized that hemostasis is rebalanced in chronic liver disease. The fall in clotting factor levels is accompanied by a parallel fall in anticoagulant proteins. High von Willebrand factor levels counteract defects in primary hemostasis. Conventional coagulation tests do not fully reflect the derangement in hemostasis and do not accurately predict the risk of bleeding. Global coagulation assays (thrombin generation, thromboelastography) reflect the interaction between procoagulant factors, anticoagu

The authors propose metal-polysilicate complexes as new inorganic polymer coagulants for the removal of colloidal suspensions. In the first part of this paper, procedures of silicic acid polymerization to attain very higher molecular weight polysilicates in a much more stable state than conventional methods are discussed. Then, a procedure for introducing metal ions such as aluminum and iron into the polymerized silicic acid is presented to give coagulation capability, i.e. charge-neutralizing capacity, to the polysilicic acid. Several new inorganic polymers are thus prepared as cationic coagu

In this study, we determined the removal of a prototype human norovirus (Norwalk virus, NV) by bench-scale alum coagulation, flocculation and sedimentation processes using reverse transcriptase polymerase chain reaction (RT-PCR) for norovirus assays. After determining optimum conditions for the coagulation, flocculation and sedimentation processes in terms of turbidity reduction, jar tests were performed using the same waters seeded with test viruses. For comparison, two other important health-related viruses, poliovirus 1 (PV1) and coliphage MS2, were included in this study. The removal of NV

Abstract Objectives Detailed and decisive information about the patients' coagulation status is important in various emergency situations. Conventional global coagulation testing strategies are often used to provide a quick overview, but several limitations particularly in the trauma setting are well described. With the introduction of direct oral anticoagulations (DOACs), a milestone for several disease entities resulting in overall improved outcomes could be reached, but at the same time providing new diagnostic challenges for the emergency situation.
