The increase in airway responsiveness induced by O3 exposure in dogs is associated with airway epithelial inflammation, as evidenced by an increase in the number of neutrophils (polymorphonuclear leukocytes) found in epithelial biopsies and in bronchoalveolar lavage fluid. We investigated in 10 healthy, human subjects whether O3-induced hyperresponsiveness(More)
STUDY OBJECTIVE To describe the clinical, radiographic, and autopsy features of AIDS-related non-Hodgkin's Iymphoma (NHL) with pulmonary involvement. DESIGN Retrospective series of patients with HIV infection and NHL with pathologically documented lung or pleural involvement. SETTING A university and a county hospital in San Francisco. PATIENTS(More)
To determine the convergent validity of four methods of physician assessment--physician interview, patient interview, chart audit, and videotaped observation--these methods were compared for their ability to detect medication regimens prescribed for patients with chronic obstructive pulmonary disease (COPD). Comparisons of data from the four methods(More)
The Internet provides patients, families, and health providers with unparalleled opportunities to learn, inform, and communicate with one another. This paper is a review of studies that have evaluated the impact of professionally facilitated Internet-based programs for diverse clinical populations on health outcomes, utilization, and user satisfaction. The(More)
Oxygen (O2) has been reported to improve exercise tolerance in some patients with chronic obstructive pulmonary disease (COPD) despite only mild resting hypoxemia (PaO2 greater than 60 mm Hg). To confirm these prior studies and evaluate potential mechanisms of benefit, we measured dyspnea scores by numeric rating scale during cycle ergometry endurance(More)
STUDY OBJECTIVE To determine whether exercise training with coaching is more effective than exercise training alone in reducing dyspnea and the anxiety and distress associated with it and improving exercise performance, self-efficacy for walking, and dyspnea with activities of daily living. DESIGN Randomized clinical trial of 51 dyspnea-limited patients(More)
To address some of the shortcomings to providing timely and convenient education and support to patients with COPD, especially in the management of dyspnea, the Internet was considered a viable medium to deliver a previously tested program at a distance to reach more patients. Older COPD patients were able to participate in the program and most were very(More)
Self-management is crucial in people with chronic diseases, and self-efficacy has been shown to impact patients' self-management. The purposes of this study were to 1) determine the effect of intervention on self-efficacy and 2) determine the relationship between domain-specific self-efficacy, walking performance, and symptom severity in patients with(More)
The efficacy of bronchoalveolar lavage and transbronchial biopsy in diagnosing lung infection was determined in 276 fiberoptic bronchoscopic examinations done on 171 patients with known or suspected acquired immunodeficiency syndrome. Of 173 pathogens (Pneumocystis carinii, cytomegalovirus, Mycobacterium avium-intracellulare, Cryptococcus neoformans, M.(More)
The Internet continues to evolve as a popular and increasingly vital channel for health information and communication among patients, families, and health providers. This article provides an overview of published studies that have described or tested Internet-based resources and interventions designed to support recovery and enhance health outcomes for the(More)
