Multicenter Study Observational Study
Thrombosis Prophylaxis and Mortality Risk among Critically Ill Adults.
The optimal approach for managing increased risk of VTE among critically ill adults is unknown. ⋯ These findings support a recommendation for prophylactic anticoagulation therapy in preference to mechanical device prophylaxis for critically ill adult patients who do not have a contraindication to anticoagulation.

Pulmonary venoocclusive disease (PVOD) is a rare lung disease, diagnosed in 5% to 10% of patients with pulmonary hypertension (PH). The incidence, prevalence, and etiology of PVOD in children are not well defined. The mortality remains high, related, at least partly, to the limited treatment options. ⋯ PVOD is an important differential diagnosis for pediatric patients with PH. CT scanning is a valuable tool to image lung abnormalities; the definitive diagnosis can only be made by examination of lung biopsy specimens, which subjects the patient to additional risk. Early listing for lung transplantation is essential, as the mean survival time is only 14 months.

Measures of physical function, daily physical activity, and exercise capacity have been proposed for the care of patients with COPD but are not used routinely in daily office care. Gait speed is a powerful and simple measure of physical function in elderly patients and seems to be a promising measure for the daily care of patients with COPD. The objective of this study was to comprehensively evaluate the determinants and factors influencing gait speed in COPD, particularly the association of gait speed with objectively measured physical activity and the most used exercise capacity field test in cardiopulmonary disease: the 6-min walk test (6MWT). ⋯ Gait speed is more indicative of exercise capacity (6MWT) than daily physical activity in COPD. Despite its simplicity, gait speed has outstanding screening properties for detecting poor and very poor 6MWT performance, making it a useful and informative tool for the clinical care of patients with COPD.
