The long-term outcomes of pulmonary thromboembolism (PTE) and/or incidence of chronic thromboembolic pulmonary hypertension (CTEPH) are not well documented. Three hundred twenty-five consecutive cases objectively diagnosed with PTE monitored for an average 16.3 months (6-50.7 months) were investigated. Data concerning recurrence, residual thrombus, mortality, and CTEPH in particular were collected. ...

Measurement of arterial elasticity can provide an important reference for understanding arterial wall changes that may occur in the early stages of atherosclerosis. Conventional correlation-based methods for evaluating arterial wall movements consider only the translation, ignoring the rotation and deformation, which limits the accuracy of measurement of arterial displacement and ...

The mechanisms mediating arterial stiffening with aging and menopause are not completely understood. We determined whether administration of tetrahydrobiopterin (BH(4)), a critical cofactor for endothelial nitric oxide synthase to produce nitric oxide, would increase vascular endothelial-dependent vasodilatory tone and decrease arterial stiffness in estrogen-deficient postmenopausal women. Additionally, we examined whether ...

Anidulafungin is an echinocandin antifungal used to treat invasive fungal infections caused by Candida or Aspergillus species. While the echinocandins are generally well tolerated, novel adverse reactions may occur. Specifically, echinocandins have been associated with histamine-mediated infusion reactions. We describe a novel case of flash pulmonary oedema associated with anidulafungin ...
