Commercial air travel is widespread, with close to 2 billion people traveling each year. The association between venous thromboembolism (VTE) and confined sitting has been established and a correlation between the distance traveled and its incidence had been documented. Most studies underscore
Hypoxia (oxygen deprivation) is known to be associated with deep vein thrombosis and venous thromboembolism. We attempted to get a better comprehension of its mechanism by going to high altitude, thereby including the potential contributing role of physical activity. Two groups of 15 healthy
Although somewhat controversial, there is good evidence that long-distance travel in general is a risk factor for venous thromboembolism, even in the absence of other risk factors. This is probably due to effects consequent to prolonged sitting but air travel in particular may be associated with
BACKGROUND
Modern air travel entails a cabin altitude between 1520 and 2440 m (5000-8000 ft) and thus exposure to mild hypoxia. There is debate as to whether hypoxia is causally related to venous thromboembolism (VTE) occurring during or after travel. One study suggested that a short period of
Patients affected by severe coronavirus induced disease-2019 (Covid-19) often experience hypoxemia due to alveolar involvement and endothelial dysfunction, which leads to the formation of micro thrombi in the pulmonary capillary vessels. Both hypoxemia and a prothrombotic diathesis have been
BACKGROUND
Venous thromboembolism (VTE) is a life-threatening condition for which thrombolytic therapy may be beneficial. The appropriate setting for the use of thrombolytic therapy remains controversial. More than 10 years ago we described the case-based practice patterns for the use of
BACKGROUND
Soluble fibrin monomer complex (SFMC) and fibrin monomer (FM) are well known as markers for hypercoagulability, but such measurements have not been investigated in detail for the neonate. To identify the presence of a hypercoagulable state in sick newborns, the behavior of SFMC with
Commercial passenger flights have been increasing around the world. The effect of these flights on health is unclear. Venous thromboembolism has been noted after recent long-distance airplane flight, even in the absence of other risk factors. Hypoxia caused by the low ambient pressure during flights
BACKGROUND
Medical therapy for chronic pulmonary thromboembolism is limited, and surgical treatment has become more frequent recently. We have performed pulmonary thromboendarterectomy on 8 patients with chronic pulmonary thromboembolism accompanied by thrombophilia.
METHODS
The patients were 6 men
INTRODUCTION: Studies have identified a great number of physiological conditions, including venous thromboembolism and hypoxia, that may give rise to medical disqualifications and in-flight incapacitations that can be costly to individuals and organizations. Over the past three decades, much
Thrombotic complications in pediatric patients are increasingly recognized due to increased use of invasive procedures, heightened awareness, improved imaging and prothrombotic lifestyle choices. Multiple risk factors are often present in pediatric patients with thrombosis. The most common risk
We consecutively inactivated both alleles of the thrombomodulin (TM) gene in murine embryonic stem (ES) cells and generated TM-deficient (TM-/-) chimeric mice. Quantitation of an ES-cell marker and protein C cofactor activity indicates that up to 50% of pulmonary endothelial cells are ES-cell
The present study was undertaken to measure fibronectin (FN) concentration in plasma and bronchoalveolar lavage fluid (BALF) with an enzyme linked immunosorbent assay (ELISA) method, to observe the distribution of FN in liver with an immunohistochemical stain method and to investigate the effect of
