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.

STudy of Active Duty Military for Pulmonary Disease Related to Environmental Deployment Exposures (STAMPEDE).
Because of increased levels of airborne particulate matter in Southwest Asia, deployed military personnel are at risk for developing acute and chronic lung diseases. Increased respiratory symptoms are reported, but limited data exist on reported lung diseases. ⋯ Evaluation of new respiratory symptoms in military personnel after service in Southwest Asia should focus on airway hyperreactivity from exposures to higher levels of ambient particulate matter. These patients may be difficult to diagnose and require close follow-up.

Continuous renal replacement therapy (CRRT) is a therapeutic technique used to support critically ill patients with acute renal failure in intensive care units. CRRT is preferred over hemodialysis for patients who cannot tolerate the rapid fluid and electrolyte shifts associated with hemodialysis because of their tenuous hemodynamic state. ⋯ This case study chronicles the successful mobilization of a patient undergoing CRRT. This experience suggests that CRRT patients who are appropriate candidates may be mobilized safely and therefore should not automatically be excluded from mobilization therapies.

The Effect of Intrathecal Administration TRPA1 Antagonists in a Rat Model of Neuropathic Pain.
The fact that transient receptor potential ankyrin 1 (TRPA1) on the peripheral terminals could attenuate hyperalgesia is widely accepted, but the effect of spinal TRPA1 in the modulation of hyperalgesia has not been fully demonstrated. In the present study, we investigated the effect of intrathecal (i.t.) administration TRPA1 antagonists on chronic pain and expression of TRPA1 and phosphorylation N-methyl-D-aspartate receptor 2B subunit (p-NR2B) in the spinal cord with chronic compression of the dorsal root ganglia (CCD) in rats. ⋯ These data demonstrated that the i.t. administration of TRPA1 antagonists could attenuate neuropathic pain in CCD rats, and this effect could be partially reduced by p-NR2B receptor expression in spinal cord.

Spinal Cord Stimulation Reduces Mechanical Hyperalgesia and Restores Physical Activity Levels in Animals with Noninflammatory Muscle Pain in a Frequency-Dependent Manner.
Spinal cord stimulation (SCS) is an effective treatment for neuropathic pain, but its effect on chronic muscle pain is unclear. We designed this study to test the effect of SCS in an animal model of noninflammatory muscle pain. ⋯ The current study shows that higher frequencies of SCS (60 and 100 Hz) significantly reduce mechanical hyperalgesia of the paw and muscle in an animal model of noninflammatory muscle pain, and 60 Hz SCS restores physical activity levels of animals, not 4 Hz.
