Background: Chronic kidney disease (CKD) is associated with an increased tendency of bleeding and thrombosis. There are multiple factors that interact with each other to cause either in CKD patients. Conventional or standard coagulation tests (SCT) have several limitations. Global coagulation test (GCT), such as Sonoclot, gives a real-time detailed analysis of coagulation status.
Materials And Methods: This is a prospective observational cross-sectional study of 50 adult CKD stage 5D (dialysis) patients conducted from January 2020 to January 2022. Clinical details were noted and blood samples were taken for conventional and global coagulation tests prior to dialysis. Correlation between SCT and GCT as well as clinical hemostatic events was analyzed.
Results: Fifty patients were enrolled. Bleeding and thrombosis occurred in 7 and 5 patients, respectively. There was a significant correlation between some SCT and GCT parameters. None of the SCT parameter derangement was associated with any thrombotic episodes except increased fibrinogen level which was associated with thrombotic events. On the contrary, patients with hypocoagulability according to SCT actually had thrombotic events. Parameters of GCT, such as clot rate, time to peak, and platelet function were significantly associated with thrombotic episodes.
Conclusion: SCT and GCT parameters do not correlate with each other. SCT is not associated with clinically significant bleeding and thrombotic events. Some GCT parameters are associated with thrombotic events. GCT are real time and are better than SCT to reflect the coagulation status in patients on dialysis.

The thrombotic physiopathology of antiphospholipid syndrome (APS) is complex, heterogeneous, and dynamic. While venous thromboembolism (VTE) is the most common initial presentation, arterial thrombotic events (ATE) become more frequent in advanced stages and are associated with high morbidity and mortality. Despite the use of oral anticoagulants (OACs), thrombotic APS remains associated with a high risk of recurrent thrombosis.

Neutrophil extracellular traps (NETs) have received significant attention in recent years for their role in both the immune response and the vascular damage associated with inflammation. Platelets have been described as critical components of NETs since the initial description of this physio-pathological response of neutrophils. Platelets have been shown to play a dual role as responders and also as stimulators of NETs.

Background: Despite multiple techniques, portal vein (PV) inflow reconstruction during living donor liver transplantation (LDLT) for patients with biliary atresia (BA) and small-diameter PV remains a challenge. The use of PV interposition grafts has emerged as a promising therapeutic strategy to mitigate complications and reinterventions.
Methods: We conducted a retrospective multi-center cohort study of patients under 3 years of age (n=85) undergoing LDLT for biliary atresia using PV interposition grafts.

Study Design: Systematic review and meta-analysis.
Objective: To determine whether venous thromboembolism (VTE) prophylaxis is necessary after spine trauma and to assess the efficacy and safety profiles of anticoagulation agents.
Summary Of Background Data: Venous stasis, endothelial disruption, hypercoagulability, and orthopedic injury in spine trauma predispose 12%-64% of patients to deep vein thrombosis (DVT).
Donor after circulatory death in pancreas transplantation: a scoping review of the literature.

The growing disparity between the demand for pancreas transplants and the availability of suitable organs underscores the urgent need for innovative donor strategies, including the utilization of donors after circulatory death (DCD). This scoping review presents a comprehensive comparative analysis of transplantation outcomes between DCD and donors after brain death (DBD), focusing on pancreatic graft survival, postoperative complications, and functional metrics such as graft performance and HbA1c levels. Although DCD grafts were suspected to be associated with higher rates of early complications, including delayed graft function and thrombosis, altogether resulting from potentially more ischemia-reperfusion injuries, their long-term outcomes are comparable to those of DBD grafts.
