COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is associated with hypercoagulability and increased incidence of thrombotic events. In this study, we investigated the levels of neutrophil extracellular trap biomarkers and von Willebrand factor to assess if these could predict the occurrence of a thrombotic event in COVID-19 patients. We enrolled 202 patients hospitalized with symptomatic COVID-19 infection. Of those, 104 patients did not experience any type of thrombotic events before or during their hospitalization. These patients were compared to the other cohort of 98, who experienced thrombotic events before or during their hospitalization. In total, 61 patients who experienced thrombotic events had the event after initial blood collection, so the predictive capacity of biomarkers in these patients was evaluated. Citrullinated histone H3 was the best predictive biomarker for thrombotic events in COVID-19 regardless of age, sex, and race; disease severity was also a significant predictor in most thrombotic event groups. These results may better inform treatment and prophylaxis of thrombotic events in COVID-19 and similar viral illnesses in the future to improve outcomes and reduce mortality.

Use of Direct Oral Anticoagulation for Isolated Distal Deep Vein Thrombosis in Japanese Orthopedic Patients.

Although direct oral anticoagulants (DOAC) have become widely used, little is known about the efficacy of DOAC for isolated distal deep vein thrombosis (DVT). In-hospitalized orthopedic patients with isolated distal DVT who were diagnosed from 2016 to 2018 were enrolled and were followed for 1 year. Embolic events included symptomatic pulmonary embolism (PE) and DVT extension above the knee.

Antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) are similar to be characterized by thromboembolic events and various clinical manifestations. We experienced a 21-year-old man with acute iliocaval deep vein thrombosis (DVT). Primary APS was initially diagnosed on the criteria, and after multidisciplinary treatment, iliocaval DVT was gradually regressed.

Aging exerts a profound impact on the hematopoietic system, leading to increased susceptibility to infections, autoimmune diseases, chronic inflammation, anemia, thrombotic events, and hematologic malignancies. Within the field of experimental hematology, the functional decline of hematopoietic stem cells (HSCs) is often regarded as a primary driver of age-related hematologic conditions. However, aging is clearly a complex multifaceted process involving not only HSCs but also mature blood cells and their interactions with other tissues.

Introduction: No clear guidelines exist for unfractionated heparin (UFH) monitoring in adult patients on veno-arterial extracorporeal life support (VA-ECLS) for refractory cardiogenic shock. In this study, we sought to compare outcomes between anti-factor Xa (FXa) and activated partial thromboplastin time (aPTT) strategies for UFH monitoring during VA-ECLS.
Methods: This is a single-center, retrospective review of VA-ECLS patients who received UFH in the cardiothoracic intensive care unit between July 2019 and November 2023.

Background: Adults with congenital heart disease (ACHD) can face a lifelong risk of premature cardiovascular events. Endothelial dysfunction and arterial stiffness may be some of the key mechanisms involved. Early identification of endothelial damage in ACHD could be crucial to mitigate the adverse events.
