[Purpose] Current studies report that patients with chronic obstructive pulmonary disease (COPD) may also have arteriosclerosis. This study aimed to investigate the relationship between respiratory function and arterial stiffness in healthy workers using the brachial-ankle pulse wave velocity (baPWV). [Subjects and Methods] This study included 104 male Japanese workers without COPD. We collecte...

The purpose of this investigation was to determine the severity of pure restrictive ventilatory impairment that results in right ventricular (RV) dilatation, increased RV wall thickness, and pulmonary hypertension. Two dimensional (2-D) echocardiography, Doppler measurements of pulmonary flow, and spirometry were performed on 26 unselected patients (17 female, 9 male) with a pure restrictive ve...

BACKGROUND The Air-Smart Spirometer is the first portable device accepted by the European Community (EC) that performs spirometric measurements by a turbine mechanism and displays the results on a smartphone or a tablet. METHODS In this multicenter, descriptive and cross-sectional prospective study carried out in 2 hospital centers, we compare FEV1, FVC, FEV1/FVC ratio measured with the Air S...

Reference equations that express indexes obtained from forced expiratory maneuvers in relation to height and/or other independent variables are lacking for infants and children with artificial airways. The present study was performed to establish normative data of forced expiration by forced deflation in healthy intubated and paralyzed infants and children and to develop prediction equations in...

BACKGROUND Lung function at the end of life depends on its peak and subsequent decline. Because obesity is epidemic in young adulthood, we quantified age-related changes in lung function relative to body mass index (BMI). METHODS The Coronary Artery Risk Development in Young Adults (CARDIA) study in 1985-86 (year 0) recruited 5,115 black and white men and women, aged 18-30. Spirometry testing...

OBJECTIVE To evaluate spirometric patterns of respiratory disorders and their relationship with functional severity and maximal expiratory flows at low lung volumes in patients with cystic fibrosis (CF). METHODS A retrospective cross-sectional study including adolescents and adults with CF. All of the patients were submitted to spirometry. Patients were classified as having preserved respirat...

Glycated hemoglobin (HbA1c) is an important diagnostic indicator of diabetes mellitus, and some authors have argued that it is related to impaired lung function in the diabetic population. However, there was rare study for association between lung function and HbA1c in the non-diabetic population. We investigated whether HbA1c below the diagnostic threshold is related to deficits in lung functi...

The SAF on Land Surface Analysis (LSA SAF) is aimed to produce operationally land surface products taking full advantage of the new EUMETSAT meteorological satellites by the end of its Initial Operational phase (2005-2007). Our main concern in LSA SAF is to develop the algorithm for retrieving Leaf Area Index (LAI) and Fraction of Vegetation Cover (FVC), as well as to validate the derived produ...

The purpose of the study was to investigate the effects of one night's sleep deprivation on the cardiorespiratory responses to exercise during the follicular and luteal phases of the menstrual cycle. We have studied nine, healthy females aged 24-35 years with regular menstrual cycles. Each subject performed spirometric tests at rest and then an incremental exercise testing during 11-13 days of ...

Fractional vegetation cover (FVC) is a vital indicator for monitoring regional and ecology. Although satellite remote sensing used to monitor long-term changes in FVC, its applications are limited by the spatial resolution. Moreover, unmanned aerial systems (UASs), obtaining large-scale images difficult, efficiency of synergy between UAS data FVC limited. This article considered mining area wit...
