Venous thromboembolism (VTE), commonly occurring in patients with testicular germ cell tumors (GCTs), is associated with increased morbidity and mortality. Prophylactic anticoagulation has been shown to decrease the risk of VTE in patients with malignancies. The objective was to evaluate the effect of low-molecular-weight heparin (LMWH) prophylaxis on the incidence of VTE and outcome in patients with GCT treated with first-line chemotherapy. In this retrospective study, 353 chemotherapy-naive GCT patients were treated with first-line chemotherapy at the National Cancer Institute, Bratislava, Slovakia (2000-2017). Median follow-up was 71 months. VTE was defined as any venous thrombosis or pulmonary embolism, confirmed by imaging, occurring during first-line chemotherapy. Exclusion criteria were LMWH use before starting chemotherapy and VTE on initial staging. We observed 14 (4.0%) VTE events. No visceral thromboses were observed. The difference in VTE incidence between patients with and without prophylaxis was not statistically significant (5.8% vs. 3.2%, p=0.37). We observed a trend toward longer overall survival in patients without prophylaxis (hazard ratio = 0.61, 95% confidence interval = 0.32-1.13, p=0.08). Patients with extragonadal GCT receiving VTE prophylaxis had significantly shorter survival (hazard ratio = 0.29, 95% confidence interval = 0.08-1.12, p=0.04). This effect was most likely driven by a higher incidence of treatment-related deaths in patients with extragonadal GCT receiving LMWH (p=0.06). LMWH prophylaxis was not associated with decreased VTE incidence. Moreover, there was a higher incidence of treatment-related deaths in patients with extragonadal tumor location. Low-molecular-weight heparin prophylaxis during hospitalization should not be used routinely in patients with testicular germ cell tumors receiving chemotherapy.

Traumatic brain injury (TBI) remains a leading cause of morbidity and mortality among trauma patients. The care of these patients continues to be a complex endeavor with prevention of associated complications, often requiring as much attention as that of the treatment of the primary injury. Paramount among these are venous thromboembolic events (VTE) due to their high incidence, additive effect on the risk of morbidity and mortality, and the careful balance that must be utilized in their diagnosis and treatment to prevent progression of the brain injury itself.

Background: In 2022, the American Association for Thoracic Surgery (AATS) and the European Society of Thoracic Surgeons (ESTS) published joint guidelines regarding the timing, duration, and choice of agent for perioperative venous thromboembolism prophylaxis for thoracic cancer patients. Now, 1 year after their release, we looked to assess practices and general adherence to these recommendations.
Methods: We conducted a survey among board-certified/board-eligible thoracic surgeons in the United States, between July and October 2023.
Introduction: Hemodialysis patients need long-term frequent use of parenteral anticoagulants, and the side effects need to be taken seriously. This study aimed to assess the reporting of adverse drug reactions (ADRs) following administration of unfractionated heparin (UFH), low molecular weight heparins (LMWHs), fondaparinux, and danaparoid, in relation to their usage in European Economic Area (EEA).
Materials And Methods: The total number of ADRs of each anticoagulant between 2017 to 2021 was collected using data from the EudraVigilance database.

Background: Immunothrombosis is the process by which the coagulation cascade interacts with the innate immune system to control infection. However, the formation of clots within the brain vasculature can be detrimental to the host. Recent work has demonstrated that Toxoplasma gondii infects and lyses central nervous system (CNS) endothelial cells that form the blood-brain barrier (BBB).

Diagnosis involves confirming the persistence of antiphospholipid antibodies in symptomatic patients, using validated classification criteria as a guide. The likelihood of obtaining false-positive or false-negative test results in certain settings, and the lack of standardisation between laboratory methods, are important considerations.
