Antibodies to β2-glycoprotein I (β2GPI) cause thrombosis in antiphospholipid syndrome, however the role of β2GPI in coagulation in vivo is not understood. To address this issue, we developed β2GPI-deficient mice (Apoh-/-) by deleting exon 2 and 3 of Apoh using CRISPR/Cas9 and compared the development of thrombosis in wild-type (WT) and Apoh-/- mice using rose bengal and FeCl3-induced carotid thrombosis, laser-induced cremaster arteriolar injury, and inferior vena cava (IVC) stasis models. We also compared tail bleeding times and activation of platelets from WT and Apoh-/- mice in the absence and presence of β2GPI.

Paradoxical embolism occurs when a clot originates in the venous system and traverses through a pulmonary or intracardiac shunt into the systemic circulation, with a mortality rate of around 18%. The risk factors for arterial embolism and venous thrombosis are similar, but different disease entities can lead to a hypercoagulable state of the blood, including antithrombin III (AT III) deficiency. We report the case of a 43-year-old man with a massive central pulmonary embolism with a rider embolus and concomitant aortic arch embolism with involvement of the brachiocephalic trunk, bilateral subclavian and axillary arteries, and the right vertebral artery, followed by a secondary ischaemic stroke.

Congenital factor VII (FVII) deficiency is a rare coagulation disorder that increases the risk of bleeding complications during surgery. Although laparoscopic sleeve gastrectomy (LSG) is the most common metabolic bariatric surgery (MBS), it is rarely performed in patients with congenital coagulation disorders such as FVII deficiency, due to the high risk of intraoperative and postoperative bleeding. We report the case of a 57-year-old female with class II obesity (BMI 37.

In the pursuit of personalized medicine, there is a growing demand for computational models with parameters that are easily obtainable to accelerate the development of potential solutions. Blood tests, owing to their affordability, accessibility, and routine use in healthcare, offer valuable biomarkers for assessing hemostatic balance in thrombotic and bleeding disorders. Incorporating these biomarkers into computational models of blood coagulation is crucial for creating patient-specific models, which allow for the analysis of the influence of these biomarkers on clot formation.

Background: High molecular weight kininogen (HMWK), encoded by the kininogen-1 (KNG1) gene, is a multifunctional glycoprotein closely associated with the initiation of blood coagulation, tumor growth, and other pathological processes.
Objective: We conducted a study on the clinical phenotype, genetic mutations, and molecular pathogenesis of a female patient with uterine leiomyosarcoma, who presented with HMWK deficiency and an isolated prolonged activated partial thromboplastin time (APTT).
Methods: Clinical phenotyping was conducted through APTT mixing studies, quantitative assessments of intrinsic coagulation factor activities, antigen levels of HMWK, and thromboelastography.
