Epidemiology, genetics, and subtyping of preserved ratio impaired spirometry (PRISm) in COPDGene
BACKGROUND Preserved Ratio Impaired Spirometry (PRISm), defined as a reduced FEV1 in the setting of a preserved FEV1/FVC ratio, is highly prevalent and is associated with increased respiratory symptoms, systemic inflammation, and mortality. Studies investigating quantitative chest tomographic features, genetic associations, and subtypes in PRISm subjects have not been reported. METHODS Data f...
متن کاملFEV6: a shortcut in spirometry?
D uring the past 50 yrs, the forced expiratory manoeuvre has formed the basis for the most extensively used lung function test. Although ''spirometry'' means measurement of breath and, therefore, should include all kinds of measurements related to breathing, it is now almost a convention that spirometry is synonymous with measurements involving a forced vital capacity (FVC). In his historical n...
متن کاملSpirometry in old age.
Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent in older people [1–4]. This well established fact has not, however, overcome the problem of underdiagnosis or misdiagnosis of both conditions in old age, with the inevitable effect on morbidity , and possibly mortality [1, 5]. Properly performed spirometric measurements of Forced Expiratory Volume in 1 second (FEV1) an...

fibroblasts [3]. Its action is basically opposed to that of TNF-a, which is a rather inflammatory cytokine [2]. It is considered, as well as IL-4, a major IL in the T-helper cell type 2 immune response [4]. Interestingly, IL-10 levels have been found to be high in rat tissues with pulmonary fibrosis, while in rats with IL-10 deficiency, the inflammatory response has been found to be more intens...
متن کاملSpirometry in primary care.
Canadian Thoracic Society (CTS) clinical guidelines for asthma and chronic obstructive pulmonary disease (COPD) specify that spirometry should be used to diagnose these diseases. Given the burden of asthma and COPD, most people with these diseases will be diagnosed in the primary care setting. The present CTS position statement was developed to provide guidance on key factors affecting the qual...
