Association Between Venous Mesenteric Thrombosis and Plasminogen Activator Inhibitor-1 Mutation.

Plasminogen activator inhibitor-1 (PAI-1) is central to fibrinolysis regulation, and genetic variants such as the 4G/4G genotype predispose individuals to hypercoagulability. This case highlights a 46-year-old female patient presenting with acute mesenteric venous thrombosis, where genetic evaluation revealed homozygosity for the PAI-1 4G/4G polymorphism. Management with unfractionated heparin followed by a transition to direct oral anticoagulants led to clinical resolution.

Background: The role of a prothrombotic state in atrial fibrillation (AF) progression to permanent arrythmia (PerAF) is unclear. Formation of denser and poorly lysable fibrin clots has been observed in AF patients also with sinus rhythm in association with higher stroke risk. We investigated whether altered fibrin clot properties and other prothrombotic state markers may contribute to AF transition to PerAF.

Backgrounds/aims: Central retinal artery occlusion (CRAO) is a vision-devastating emergency. However, widely-acknowledged treatment consensus is lacking and prehospital delays commonly occur. Hence, we aimed to investigate the visual outcomes of conservative treatments (CT), local intra-arterial fibrinolysis (LIF) and hyperbaric oxygen (HBO) therapy for non-arteritic CRAO (NA-CRAO) patients beyond the conventional time window.

Cardiothoracic Surgery, Northeast Georgia Medical Center Gainesville, Gainesville, USA.
Hemothorax is a serious complication following thoracic surgery, often resulting from vessel injury or rib fractures, and is typically managed with chest tube drainage. Persistent or loculated hemothorax, referred to as retained hemothorax, may require more invasive interventions, such as thoracotomy. Although the intrapleural administration of tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) has shown promise in managing pleural infections, its use for hemothorax remains controversial due to bleeding risks.

Article Synopsis
- The study aimed to investigate how fresh and stored platelet concentrates (PCs) behave during inflammation, specifically in a controlled human model of endotoxemia induced by lipopolysaccharide (LPS).
- Researchers found that LPS increased markers related to coagulation and clotting, leading to a generally lower clotting ability in subjects compared to controls, while platelet transfusions improved clotting time and strength in those with endotoxemia.
- Despite these improvements in coagulation, there were no significant differences noted between the effects of fresh versus stored platelets on coagulation parameters like thrombin-antithrombin complex (TATc) or extracellular vesicles (EVs).
