Introduction: Circulating microparticles support thrombin generation. The aim of this study is to determine the indirect microparticle activity and the parameters of thrombin generation in healthy infants.

Materials And Methods: A total of 85 infants who were brought to follow-up visits were taken into the study. Blood samples were collected. Thrombin generation parameters and indirect microparticle activity were measured.

Results: The infants were divided into four groups according to the time of follow-up visits. Mean ages were 1.18 ± 0.19 months in Group 1, 6.15 ± 0.16 months in Group 2, 12.38 ± 0.46 months in Group 3 and 24.53 ± 0.39 months in Group 4, respectively. There was no statistical difference among the age-based groups with respect to the indirect microparticle activity. The lag time and the TTP levels in Group 1 were lower than that found in Group 2. The ETP and peak levels were higher in Group 1 than that of Group 2. The ETP and peak levels in Group 2 were found lower than those found in older children, but the TTP level was found relatively higher. Statistically correlations were found between indirect microparticle activity and all parameters of thrombin generation.

Conclusions: The absence of a difference in terms of age-based microparticle levels may suggest that the features of microparticles in healthy children of this age group are similar. Age-dependent changes in thrombin generation parameters may suggest a regulation mechanism for the thrombin generation system over the first years of life. The results may provide mean values for indirect microparticle activity and thrombin generation in this healthy group.

Background: Emicizumab, a bispecific antibody that mimics factor (F)VIII, has significantly improved hemophilia A management. Although emicizumab levels can be measured, tools for estimating the hemostatic efficacy of emicizumab are lacking. Thrombin generation (TG) assays can distinguish bleeding phenotypes in persons with hemophilia A on FVIII prophylaxis and may also be used during emicizumab therapy.

The hemostatic function of platelets is complementary to blood coagulation. However, traditional platelet function tests have primarily focused on measuring platelet aggregation, reducing their clinical effectiveness for antiplatelet drug monitoring. To address this limitation, we propose a new test principle that evaluates platelet function and the effects of antiplatelet drugs through blood coagulation reactions.

Introduction: Coagulopathy following traumatic injury impairs stable blood clot formation and exacerbates mortality from hemorrhage. Understanding how these alterations impact blood clot stability is critical to improving resuscitation. Furthermore, the incorporation of machine learning algorithms to assess clinical markers, coagulation assays and biochemical assays allows us to define the contributions of these factors to mortality.

Background: Anticoagulants are the primary means for the treatment and prevention of venous thromboembolism (VTE), but their clinical standardized application still remains controversial. The present study intends to comprehensively compare the efficacy and safety of various anticoagulants in VTE.

Methods: Medline, Embase, and Cochrane Library from their inception up to August 2023 were searched to compare the efficacy and safety of various anticoagulants in VTE.
