The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has had significant impacts on pulmonary function. This study aimed to comprehensively evaluate function and structure in patients 40 days post-SARS-CoV-2 infection, employing an array of testing methodologies including spirometry, plethysmography, forced oscillometry, CT scanning. It also sought establish potential correlations between the...

OBJECTIVES The aim of this study was to assess the prevalence and determinants of post-tuberculosis chronic respiratory signs, as well as the clinical impact of a low forced expiratory flow between 25% and 75% (FEF25-75%) in a group of individuals previously treated successfully for pulmonary tuberculosis. DESIGN This was a cross-sectional study involving individuals in their post-tuberculosi...

BACKGROUND Air pollution has been associated with impaired health, including reduced lung function in adults. Moving to cleaner areas has been shown to attenuate adverse effects of air pollution on lung function in children but not in adults. METHODS We conducted a prospective study of 9651 adults (18 to 60 years of age) randomly selected from population registries in 1990 and assessed in 199...

Increases in body mass index (BMI) are reported to influence asthma response to treatment. The aim of this study was to investigate the relationship between BMI and response to treatment in a group of patients that were referred for asthma control. Effectiveness measurements in this analysis included percentage of changes in forced volume in 1 second (FEV1), forced volume capacity (FVC), FEV1/F...

Chronic hypoxemia is known to cause peripheral neuropathy (PNP) in chronic obstructive pulmonary disease (COPD) patients. We aimed to know how often PNP is encountered in such patients and the changes in the central nervous system (CNS) if any. We enrolled 32 patients (30 M, 2 F; mean age +/- SD: 61.5 +/- 8.8 years) with COPD into the study. PaO2 > or = 55 mmHg was considered as the cut-off val...

OBJECTIVES To assess the prevalence of respiratory disease in school-aged children and to determine the value of field spirometry. METHODS Data on 313 1st and 4th graders from four public schools in Lisbon were analyzed. A respiratory self-answered questionnaire and standard spirometry were performed. Descriptive and bivariate analysis was followed by multiple logistic regression. RESULTS T...

BACKGROUND/PURPOSE Patient reports of preoperative exercise intolerance and improvement after surgical repair of pectus excavatum (Pex) have been documented but not substantiated in laboratory studies. This may be because no study has been large enough to determine if pulmonary function tests (PFTs) in the Pex population are significantly different from the normal population, and none has asses...

obstruction (reduced FEF25-75 and FEF75-85) as shown in 8,720 asbestos-exposed workers who at various times during this evolution show irregular opacities as seen in the chest x-ray films.1 Thus, the disease's functional signs precede the radiographic manifestations. This was confirmed pathologically as fibrosis was found far more often on tissue sections when lung was examined from asbestos wo...

Objective: To characterize the cardiorespiratory function and state of oxidative stress resulting from exposure towood smoke in women who live at high altitude (3,850 m a.s.l.). Materials methods: An observational case-series study. The was analyzed, thebiomarkers malondialdehyde (MDA) carboxyhemoglobin (COHb) were quantified. Measures centraltendency dispersion determined. statistical methods ...
