Symptomatic intracerebral hemorrhage (sICH) occurs in up to 7% of stroke patients treated with thrombolytic therapy. There are limited data on the effectiveness of the reversal agents used for intravenous tissue plasminogen activator related intracranial bleeds. We report a patient with sICH following intravenous thrombolysis whose intracerebral hemorrhage continued to expand despite treatment with platelets and cryoprecipitate, needing recombinant factor VIIa use for stabilization before surgical evacuation. Factor VIIa along with routine reversal agents following intravenous thrombolysis related sICH may further enhance clot stability and reduce the risk of hematoma expansion. It could be a bridge to definitive surgical management in those patients.

Background: The development of anticoagulants that provide antithrombotic efficacy without a concomitant bleeding risk remains an unmet clinical need in thrombosis. Although direct oral anticoagulants (DOACs) have a reduced incidence of major bleeding compared with warfarin, they still carry a bleeding risk, resulting in a suboptimal therapeutic index. Epidemiologic data suggest that inhibiting activated factor XI (FXIa) may offer an improved safety profile with respect to bleeding risk compared with current-generation DOACs.

Formation of the extrinsic complex (EC) on cell surfaces is the event that triggers the coagulation cascade. Tissue factor (TF) and factor VIIa (FVIIa) form the EC together with factor X (FX) on phosphatidylserine-containing membranes, leading to FX activation by TF:FVIIa. This lipid dependence has made experimental characterization of the EC structure challenging.

Background: Hemorrhagic stroke (HS) is associated with high risk of mortality or disability. To date, up to 25% of HSs are associated with anticoagulants and antiplatelet agents. Early hemostatic therapy and correction of effect of antithrombotic drugs in patients with HS significantly reduce the risk of adverse outcomes.

Tissue factor (TF) and protease-activated receptor 2 (PAR2) have been associated with the progression of cancer, while integrins are essential for the adhesion and migration of cancer cells. This study aimed to explore the cross-talk between the TF:FVIIa complex, PAR2 signaling, and the expression of integrin α1 in cervical cancer cells. Utilizing data from The Cancer Genome Atlas (TCGA), the research examined the relationship between the TF and PAR2 genes and the integrin α1 gene (ITGA1) in reproductive cancers, revealing a positive correlation between integrin α1 expression and both TF and PAR2 genes.

Introduction: While numerous studies have established associations between brain-derived neurotrophic factor (BDNF) and cognitive functioning, limited research has delved into the role of BDNF concerning cognitive outcomes in atherosclerosis-related conditions. This study aimed to investigate the correlations between cognitive performance, serum BDNF levels, and the BDNF Val66Met polymorphism in individuals diagnosed with chronic limb ischemia (CLI).
Participants And Procedure: The study encompassed 159 CLI patients (52 females, 107 males) aged 59-73 years.
