BACKGROUND Spirometry-based parameters of pulmonary function such as forced expiratory volume in 1 second (FEV1) have prognostic value beyond respiratory morbidity and mortality. FEV1 divided by height cubed (FEV1/Ht(3)) has been found to be better at predicting all-cause mortality than the usual standardization as percentage of predicted "normal values"(More)
BACKGROUND Smoking remains a leading health risk factor among Europeans. Tobacco, together with other factors, will lead to an expansive epidemic of chronic diseases, including COPD, among the working population in Russia. The general aim of the RESearch on the PrEvalence and the diagnosis of COPD and its Tobacco-related etiology (RESPECT) study is to gain(More)
BACKGROUND Spirometry is an important test for the diagnosis of respiratory diseases, yet it is underused especially in older adults. Several predictors of good-quality spirometry in this age group have been reported, based mainly on in/outpatients of geriatric and/or respiratory units. AIMS This study aims to assess predictors of poor-quality spirometry(More)
INTRIDUCTION Currently available low orbital (LO) satellite navigational systems (like the Russian "Tsykada" satellites and American "Transit"-Navy Navigation Satellite System) having nearly circular orbits at 1000-1150 km altitudes, and ground receiving chains provide a possibility to yield a series of tomographic data along a set of rays and to get 2D RT(More)
