1. Prevalence of thrombophilia-associated genetic risk factors in blood donors of a regional hospital in southern Brazil
ABSTRACT Introduction: Thromboembolic events occur due to an imbalance in the hemostasis and some factors associated with this condition can be inherited. In order to evaluate the frequency of genotypes considered to be common hereditary risk factors for thrombophilia associated with venous thrombosis (g.1691G>A and g.20210G>A) and hyperhomocysteinemia (g.6

2. Endoscopic Holmium Laser harvesting of bladder mucosal graft for substitution urethroplasty
ABSTRACT Introduction: Tissue transfer has been used in urethral reconstruction for decades, and several grafts have been described (1, 2). The ideal graft would have optimal tissue characteristics and lead to minimal morbidity at the donor site. Urethroplasty using bladder mucosa was first described by Memmelaar in 1947 (3). The main limitation in using bl

3. Atrial Fibrillation and Use of Rivaroxaban: Performance of the Prothrombin Time / INR as a Function of Time After Blood Collection
Abstract Background Traditionally, the most effective therapy in the prevention of stroke in patients with atrial fibrillation (AF) has been oral anticoagulation with vitamin K inhibitors, particularly warfarin, whose disadvantages and adverse effects have led to their replacement by "direct oral anticoagulants", as factor X inhibitor. Objectives This st

4. Guidance on diagnosis, prevention and treatment of thromboembolic complications in COVID-19: a position paper of the Brazilian Society of Thrombosis and Hemostasis and the Thrombosis and Hemostasis Committee of the Brazilian Association of Hematology, Hemotherapy and Cellular Therapy
ABSTRACT Hemostatic abnormalities and thrombotic risk associated with coronavirus disease 2019 (COVID-19) are among the most discussed topics in the management of this disease. The aim of this position paper is to provide the opinion of Brazilian experts on the thromboprophylaxis and management of thrombotic events in patients with suspected COVID-19, in the

5. Hemostasis profile in COVID-19 infection
RESUMO: A identificação da diversidade de pestivírus bovinos que circulam no campo é fundamental para a avaliação contínua dos testes de diagnóstico e composição de vacina. Neste artigo, realizamos a caracterização genética e antigênica de doze pestivírus bovinos isolados na região oeste do Rio Grande do Sul, Brasil. Os vírus foram isolados

6. Venous thromboembolism in childhood: where is Brazil after 20 years?
Abstract Due to the longer survival of critically ill children, venous thromboembolism is a problem which is becoming increasingly recognized in pediatric practice. In the last decades, several international studies have been published, shedding a light upon the epidemiology of this disease during childhood. These data show peculiarities in the clinical pres

7. RISK OF BLEEDING COMPLICATIONS IN PERCUTANEOUS BILIARY DRAINAGE: THE PARADOX OF THE NORMAL HEMOSTASIS
RESUMO Racional: A drenagem biliar percutânea é procedimento seguro. O risco de complicações hemorrágicas é aceitável. Frequentemente, os pacientes com obstruções biliares apresentam distúrbios de coagulação, aumentando o risco de sangramento. Por esse motivo, eles devem sempre ser adequados aos parâmetros da hemostasia. Objetivo: Determinar s

8. Cicatrização: uso de matriz de colágeno
Resumo A matriz de colágeno Ologen TM é um novo agente antifibrótico composto por uma matriz porosa de atelocolageno tipo I e glicosaminoglicanos reticulados, que pode ser utilizado como uma alternativa para a modulação da cicatrização nas cirurgias. Por ser altamente poroso e biodegradável, este implante auxilia nos processos de reparação fisioló

10. Impact of Arterial Procedures on Coagulation and Fibrinolysis - A Pilot Study
Abstract Objective: The main goal of our study was to assess the impact of vascular procedures on the activity of hemostatic and fibrinolytic pathways. Methods: We enrolled 38 patients with ≥ 45 years old undergoing surgery for abdominal aortic aneurysm or peripheral artery disease under general or regional anesthesia and who were hospitalized at least o

11. Functional and biological insights of rCollinein-1, a recombinant serine protease from Crotalus durissus collilineatus
ABSTRACT Background: The prevalent class of snake venom serine proteases (SVSP) in Viperidae venoms is the thrombin-like enzymes, which, similarly to human thrombin, convert fibrinogen into insoluble fibrin monomers. However, thrombin-like serine proteases differ from thrombin by being unable to activate factor XIII, thus leading to the formation of loose c

12. Revisiting the roles of VHR/DUSP3 phosphatase in human diseases
Protein tyrosine phosphatases have long been considered key regulators of biological processes and are therefore implicated in the origins of various human diseases. Heterozygosity, mutations, deletions, and the complete loss of some of these enzymes have been reported to cause neurodegenerative diseases, autoimmune syndromes, genetic disorders, metabolic di
