Background: Any surgical procedure carries a risk for venous thromboembolism (VTE), albeit variable. Improvements in medical and surgical practices and the shortening of care pathways due to the development of day surgery and enhanced recovery after surgery, have reduced the perioperative risk for VTE.

Objective: A collaborative working group of experts in perioperative haemostasis updated in 2024 the recommendations for the Prevention of perioperative venous thromboembolism published in 2011.

Background: Vitamin K (VK) deficiency (VKD) impairs γ-carboxylation of VK-dependent factors (VKDFs), resulting in higher factor (F)II levels measured by Ecarin (FIIE) reagents (that convert des-γ-carboxylated FII to meizothrombin) than by prothrombin time (FII) reagents.

Objectives: To evaluate FII/FIIE abnormalities among patients assessed for coagulopathies and identify findings predictive of coagulopathy improvement after VK.

Methods: We retrospectively assessed consecutive cases from 2002 to 2021 with FII/FIIE tests and the sensitivity and specificity of FII/FIIE ratios and FIIE-FII differences for VKD defined as international normalized ratio correction/improvement of ≥0.

Human induced pluripotent stem cells (iPSC) have the potential to produce desired target cell types in vitro and allow for the high-throughput screening of drugs/chemicals at population level thereby minimising the cost of drug discovery and drug withdrawals after clinical trials. There is a substantial need for the characterisation of the iPSC derived models to better understand and utilise them for toxicological relevant applications. In our study, iPSC (SBAD2 or SBAD3 lines obtained from StemBANCC project) were differentiated towards toxicologically relevant cell types: alveolar macrophages, brain capillary endothelial cells, brain cells, endothelial cells, hepatocytes, lung airway epithelium, monocytes, podocytes and renal proximal tubular cells.

Article Synopsis
  • Light transmission aggregometry (LTA) is crucial for diagnosing platelet function disorders and von Willebrand disease, especially in patients with low platelet counts (L-PRP), but its application in these cases has been underexplored.* -
  • A study assessed the effectiveness of a diagnostic LTA strategy for L-PRP samples from 192 patients, revealing that many had significant aggregation abnormalities, particularly in those with very low platelet counts.* -
  • The findings suggest that adapting LTA to consider thrombocytopenia severity can effectively diagnose conditions like von Willebrand disease and other platelet-related disorders.*
