AI Article Synopsis

  • A study measured thrombin generation in 59 patients with unstable angina during unstable and stable periods, comparing results to 31 healthy controls.
  • Thrombin generation was significantly higher during the unstable period compared to both the healthy controls at rest and the stable period in patients (p < 0.0001).
  • The variations in thrombin generation were linked to how long the patients had been experiencing unstable angina, rather than the improvement in the severity of their coronary artery blockages.

Article Abstract

Platelet-dependent thrombin generation was assessed during both unstable and stable periods in 59 patients with unstable angina and at rest in 31 healthy controls. Thrombin generation during the unstable period was significantly greater than that at rest in the healthy control group (p < 0.0001) and that during the stable period (p < 0.0001). Changes in thrombin generation were related to the time after onset of unstable angina, not to degree of improvement in the severity of coronary stenosis.

Purpose: This study explores the potential interaction of brolucizumab with platelets and its effects on platelet activation and reactivity, crucial in retinal vasculitis and retinal vascular occlusion. Safety concerns remain of interest, although brolucizumab showed superior retinal efficacy and reduced injection frequency compared to other licensed anti-VEGF agents.

Methods: Resting and activated platelets of healthy volunteers were pretreated with brolucizumab at the following concentrations 0.

Polyamidoamine (PAMAM) dendrimers, with their unique structural versatility and tunable surface functionalities, have emerged as promising nanomaterials for a wide range of biomedical applications. However, their in vivo use raises concerns, as unintended interactions between dendrimers and blood components could disrupt the delicate hemostatic balance and lead to serious complications like bleeding or thrombosis. In this study, we explored the impact of low-generation PAMAM dendrimers on the kinetics of fibrin clot formation, along with their influence on the structure, properties, and resistance to lysis of the resulting clots.

Altered thrombin generation with prothrombin complex concentrate is not detected by viscoelastic testing: an in vitro study.

Br J Anaesth

Background: Bleeding guidelines currently recommend use of viscoelastic testing (VET) to direct haemostatic resuscitation in severe haemorrhage. However, VET-derived parameters of clot initiation, such as clotting time (CT) and activated clotting time (ACT), might not adequately reflect a clinically relevant interaction of procoagulant and anticoagulant activity, as revealed by thrombin generation assays. The aim of this study was to evaluate the ability of CT and ACT to indicate thrombin generation activity.

INCREASED CITRULLINATED HISTONE H3 LEVELS AND ACCELERATED THROMBIN KINETICS IN TRAUMA PATIENTS WHO DEVELOP VENOUS THROMBOEMBOLISM.

Shock

December 2024

Division of Trauma, Critical Care, and General Surgery, Department of Surgery, Mayo Clinic, 200 1st St. SW, Rochester, MN, United States 55905.

Background: Neutrophil extracellular traps (NETs), and its formation and release, known as NETosis, may play a role in the initiation of thrombin generation (TG) in trauma. The objective of this study was to assess whether trauma patients, who develop symptomatic venous thromboembolism (VTE), have increased levels of plasma citrullinated histone H3 (CitH3) and accelerated TG kinetics.

Methods: Patients presenting to a Level I Trauma Center as trauma activations had samples collected within 12 hours of time of injury (TOI), alongside healthy volunteers (HV).

Available evidence suggests that various medical/rehabilitation treatments evoke multiple effects on blood hemostasis. It was therefore the aim of our study to examine whether fascial manipulation, vibration exercise, motor imagery, or neuro-muscular electrical stimulation can activate the coagulation system, and, thereby, expose patients to thrombotic risk. Ten healthy young subject were enrolled in the study.
