A new suite of assays are helping identify drug-related effects on hemostasis, which can lead to excessive blood loss or inversely thrombus formation.
2018 Elsevier Inc. All rights reserved. Transfusion medicine physicians and laboratory scientists are confronted daily with hemostasis and thrombosis-related concerns as they select and administer blood components, coagulation factor concentrates, anticoagulants, and agents to manage anticoagulant therapy. This chapter provides an introduction and overview of hemostasis. Primary hemostasis focuses on platelet function and interactions with the vasculature, endothelium, and the coagulation mechanism. Secondary hemostasis focuses on the coagulation cascade and is subdivided into the extrinsic, intrinsic, and common enzymatic pathways. Coagulation also includes control systems such as protein C, protein S, and antithrombin, and fibrinolysis. Depending on the defect, hemostasis disorders may be congenital or acquired, resulting in hemorrhage or thrombosis. The questions in this chapter will explore normal hemostasis, disorders of hemostasis, and the laboratory assays that predict, identify, and ...
A library of hyperbranched polyglycerols (HPGs) functionalized with different mole fractions of zwitterionic sulfabetaine and cationic quaternary ammonium ligands was synthesized and characterized. A post-polymerization method was employed that utilized double bond moieties on the dendritic HPG for the coupling of thiol-terminated ligands via UV initiated thiol-ene "click" chemistry. The proportions of different ligands were precisely controlled by varying the ligand concentration during the irradiation process. The effect of the polymer library on hemostasis was investigated using whole human blood. It was found that polymer with ≥40% of alkenes converted to positive charges and the remainder to sulfabetaines caused hemagglutination at ≥1 mg/mL, without causing red blood cell lysis. The quaternary ammonium groups can interact with the negative charged sites on the membranes of erythrocytes, which provides the bioadhesion. The zwitterionic sulfabetaine evidently provides a hydration layer to ...
Epidemiological, clinical, and experimental studies have shown that dyslipidemia associated with insulin resistance and hypertension also may include a procoagulant state with activation of the coagulation system and inhibition of the fibrinolytic activities.11 24 25 In the early prospective epidemiological studies, it was shown that FVIIc, fibrinogen, PAI-1a, and tPAag may represent independent risk factors for development of CHD.11 24 25 In a recent study of patients with combined hyperlipemia, we have confirmed that FVIIag and FVIIc are correlated with the triglyceride-rich lipoproteins, particularly with the concentration of intermediate density lipoproteins (IDL) TAGs.21 TFPIa showed a significant correlation with the concentration of LDL, a lipoprotein fraction also associated with increased risk for CHD.. In human plasma, 80% of TFPI is bound to lipoproteins, especially LDL, whereas 10% to 20% circulates in a free form.26 A positive correlation between the total plasma TFPI activity and ...
BACKGROUND: Previous studies have suggested that several hemostatic and inflammatory variables, which are risk predictors for arterial or venous thrombosis, increase with age. However, there is a lack of data from large population studies for reliable estimates of reference ranges. OBJECTIVES: To establish reliable reference ranges of hemostatic and inflammatory variables for 5-year age groups in older men and their implications for pathogenesis and diagnosis. PATIENTS AND METHODS: A total of 3861 men aged 60-79 years at the 20 years follow-up of the British Regional Heart Study. RESULTS: Several variables increased with age. The greatest median increases between 60-64 and 75-79 years age groups were observed for fibrin D-dimer (91%) and C-reactive protein (CRP) (57%). Significant median increases were also observed for von Willebrand factor antigen (23%), tissue plasminogen activator antigen (11%), factor VIII (10%), and fibrinogen (8%). In contrast, levels of classical cardiovascular risk factors

The global coagulation analyzers market is estimated to grow at a lower CAGR in developed countries; however, it is expected to witness high growth in emerging countries such as China, India, and Brazil in the next five years. Growth in the coagulation analyzers market is driven by factors such as increasing adoption of automated hemostasis instruments by diagnostics laboratories, development of high-throughput hemostasis analyzers, developments in high-sensitivity point-of-care coagulation analyzers, and introduction of technologically advanced hemostasis instruments. However, slow adoption of advanced hemostasis instruments in emerging economies and high cost of hemostasis analyzers are restraining the growth of this market.. In this report, the global coagulation analyzers market has been segmented based on the type of product (clinical laboratory analyzers, point of care testing analyzers) end users (diagnostic laboratories, stand-alone hospitals, research institutes, and other end users), ...
There is evidence from recent studies that VEGF is stored in human megakaryocytes and is released from platelets on stimulation with thrombin.14 15 These studies were performed under in vitro conditions in the absence of important determinants of in vivo clotting such as the vessel wall, blood flow, and clotting proteases. Thus, it is uncertain if their in vitro observations are of relevance for the in vivo circumstances. The technique applied in our study covers many mechanisms relevant for hemostatic plug formation in vivo. It is performed directly on human subjects and takes into account the interaction between blood cells, endothelium, and various plasma proteins under physiological flow conditions. Thus, we believe that the experimental approach applied in this study is appropriate for investigating the mechanisms important for plug formation under conditions close to the in vivo circumstances.. The principal finding of our study was that much higher concentrations of VEGF are detectable in ...
INTRODUCTION: Cirrhosis is one of the commonest diseases affecting man. Hepatic cirrhosis can occur at any age and often causes prolonged morbidity. It frequently manifests itself in younger adults and is an important cause of premature death. Liver disease produces a diverse range of haemotological effects. Liver disease can affect all the formed elements of blood RBCS, WBCS, and platelets. Liver disease has important effects on haemostasis. The liver plays a central role in the synthesis of many proteins and the maintenance of metabolic homeostasis. It is therefore not surprising that the development of clinically important liver diseases is accompanied by diverse manifestations. Although some functions are more sensitive than others, the liver has considerable reserve capacity, so, minimal or even moderate cell injury may not be reflected by measurable functional changes. Impaired liver functions are most evident in the patient with advanced liver disease, and the manifestations are similar ...
The process of preventing blood loss from a vessel or organ of the body is referred to as hemostasis. The term comes from the Ancient Greek roots "heme" meaning blood, and "stasis" meaning halting; Put together means the "halting of the blood".[3] The origin of hemostasis dates back as far as ancient Greece; first referenced to being used in the Battle of Troy. It started with the realization that excessive bleeding inevitably equaled death. Vegetable and mineral styptics were used on large wounds by the Greeks and Romans until the takeover of Egypt around 332BC by Greece. At this time many more advances in the general medical field were developed through the study of Egyptian mummification practice, which led to greater knowledge of the hemostatic process. It was during this time that many of the veins and arteries running throughout the human body were found and the directions in which they traveled. Doctors of this time realized if these were plugged, blood could not continue to flow out of ...

A method and system for achieving hemostasis (the stoppage of bleeding) is described. RF (radio frequency) energy is used to ablate the surface of tissue to stop bleeding. The depth of destruction of the tissue can be controlled so as to desiccate and coagulate the tissue. In one implementation, an electrode carrier including bipolar electrodes is applied to the tissue, and RF energy transmitted through the bipolar electrodes to ablate the tissue. A layer of desiccated tissue can be created as well as coagulation of the tissue to achieve hemostasis.

Blood is a vital part of the human physiology; a transport system that brings nutrients and oxygen to sustain living cells and simultaneously facilitates the removal of carbon dioxide and other waste products from the body. To assure the continuity of these functions, it is of uttermost importance to keep the flowing blood inside the vascular system at any cost. The principal components of the haemostatic system are the blood platelets and the plasma coagulation system, both working in concert to create a blood stopping haemostatic plug when a vessel is ruptured. In modern health care, methods for treatment and diagnostics often implicate the contact between blood and artificial materials (biomaterials). Biomaterial surfaces may activate platelets and the coagulation cascade by exposing a surface that during blood contact shares certain characteristics with surfaces found at the site of vascular injury. Therefore it is of great importance that the mechanisms behind the interactions between ...

The tissue factor (TF) pathway serves both hemostasis and cell signaling, but how cells control these divergent functions of TF remains incompletely understood. TF is the receptor and scaffold of coagulation proteases cleaving protease activated receptor (PAR) 2 that plays pivotal roles in angiogenesis and tumor development. Here we demonstrate that coagulation factor (F) VIIa elicits TF cytoplasmic domain-dependent pro-angiogenic cell signaling independent of the alternative PAR2 activator matriptase. We identify a Lys-Gly-Glu (KGE) integrin binding motif in the FVIIa protease domain that is required for association of the TF-FVIIa complex with the active conformer of integrin β1 ...
