NCT01363531
The general hypothesis is that delayed antibiotic treatment strategies present similar effectiveness, when compared with non-prescription of antibiotics or the prescription of antibiotics, in the non-complicated acute respiratory tract infections.
NCT00737906
The primary goal of this post-marketing surveillance study is to assess whether surgical turbinate reduction performed using a Coblation® device is associated with reduced nasal obstruction symptoms.
NCT01852006
Conventional approaches to relieve dyspnea (respiratory discomfort) in chronic obstructive pulmonary disease (COPD) have focused on improving respiratory motor drive (e.g., hyperoxia) and/or dynamic respiratory mechanics (e.g., bronchodilators). Although these approaches yield meaningful symptom improvements there remains many COPD patients incapacitated by dyspnea. Accumulating evidence suggests that abdominal binding (AB) is a potentially novel method of improving respiratory muscle function and, by extension, dyspnea and exercise tolerance in COPD. Thus, the purpose of this randomized, cross-over study is to test the hypothesis that AB improves exertional dyspnea and exercise tolerance in symptomatic patients with COPD by improving dynamic respiratory muscle function. To this end, the investigators will examine the effects of AB on detailed assessments of baseline pulmonary function (spirometry, plethysmography), dyspnea (sensory intensity \& affective responses), neural respiratory drive (diaphragm EMG), contractile respiratory muscle function (esophageal, gastric \& transdiaphragmatic pressures), ventilation, breathing pattern and cardiometabolic function during symptom-limited constant load cycle exercise (75% Wmax) in 20 patients with GOLD stage II/III COPD.
