An estimated 90 million subjects in the USA have a history of smoking, and are therefore at risk of developing smoke-related lung diseases including lung cancer, chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis. An ageing population, the lack of effective diagnostic and therapeutic approaches, and the modest impact of smoking cessation strategies largely explain why chronic l...

conclusions inhalation of tiotropium bromide in combination with pulmonary rehabilitation could improve some plethysmographic lung volumes and clinical outcomes in patients with chronic pulmonary disease due to sm. short-term prescription of pulmonary rehabilitation has no effect on cpet of patients. patients and methods in a randomized clinical trial, using convenient sampling method, 54 patie...

background: non-communicable diseases (ncds) annually kill over 35 million people worldwide. they are responsible for nearly two-thirds of the world's deaths. global health is facing a dramatic change. for the first time in human history, more than 80% of ncd-related deaths are in low- and middle-income countries. countries throughout the world are expected to lose significant amounts of nation...

Ageing is the main risk factor for major non-communicable chronic lung diseases, including chronic obstructive pulmonary disease, most forms of lung cancer and idiopathic pulmonary fibrosis. While the prevalence of these diseases continually increases with age, their respective incidence peaks at different times during the lifespan, suggesting specific effects of ageing on the onset and/or path...

A previously reported computer analysis has been used to provide numerical ventilation-perfusion lung scan data, for comparison with tests of airways function and results of arterial blood gas analysis in 11 patients with pulmonary embolism, 18 with asthma, and 37 with chronic obstructive lung disease. In pulmonary embolism an index of underperfusion showed high sensitivity, and an index of ven...
