BACKGROUND Some technologists worry that patients with very severe lung disease are unable to complete several spirometry maneuvers, which require considerable effort. METHODS We retrospectively selected all spirometry tests with an FEV1 < 35% predicted done by adult subjects sent to our pulmonary function laboratory during a 3-y period. We determined the rates and correlates of poor quality ...
BACKGROUND Despite the very high background prevalence of HIV and smoking-related diseases in sub-Saharan Africa, very little is known about the presentation of lung cancer in HIV-infected individuals. METHODS We prospectively compared HIV-positive (n=44) and HIV-negative lung cancer patients (n=425) with regard to demographics, cell type, performance status and umour node metastasis staging ...
Idiopathic pulmonary fibrosis is a chronic fibrotic lung disease of unknown cause that occurs in adults and has a poor prognosis. Its epidemiology has been difficult to study because of its rarity and evolution in diagnostic and coding practices. Though uncommon, it is likely underappreciated both in terms of its occurrence (ie, incidence, prevalence) and public health impact (ie, health care c...
Current knowledge about factors determining outcome of asthma is limited, but observations over the last few decades suggest that active asthma has a negative impact on the longitudinal changes in lung function. This review aims to give an overview of the present knowledge concerning longitudinal changes in lung function, including clinical markers for distinctly poor outcome with regard to lun...
Background and Objective: Obesity and body fat percentage seem to be associated with respiratory problems, although the mechanism of this correlation is not very clear. The aim of this study was to investigate the effect of 12-week HIIT training on lung function, serum leptin level and lipid profile in inactive obese men. Materials and Methods: Twenty-two inactive obese men aged 18 to 30 y...
BACKGROUND ATS/ERS Task Force has highlighted that special attention must be paid when FEV1 and FVC are concomitantly decreased (<5th percentile) and the FEV1/FVC ratio is normal (>5th percentile) because a possible cause of this non specific pattern (NSP) is collapse of small airways with normal TLC measured by body plethysmography (>5th percentile). Our objectives were to determine the main l...
Background: Flour dust is one of the allergens in the workplaces and its occupational exposure can cause respiratory impairments. The purpose of this study was to investigate the respiratory effects of exposure to flour dust in flour mill workers. Methods: This cross-sectional study was carried out at 6 flour producing factories in Razavi and South Khorasan provinces, Iran. Study subjects incl...
Introduction: Asthma is a chronic inflammatory and reversible airway disease. Modification of lifestyle by increasing obesity prevalence and decreasing physical activity is one of the main cause of its rising prevalence. Patients with asthma have lower fitness than their healthy counterparts. Regular exercise improves fitness in Asthmatic patients and reduces the symptoms of the disease. Hence,...
Background: There is growing evidence that diabetes mellitus (DM) is an important risk factor for tuberculosis (TB). A significant number of DM patients have poor glycemic control. This study was carried out to find the impact of poor glycemic control on newly diagnosed smear-positive pulmonary tuberculosis patients with type-2 diabetes mellitus in a tertiary care hospital.Methods: In a hospita...
Within their small air sacs, our lungs exchange oxygen (O 2 ) from the for carbon dioxide (CO produced by bodies. In these spaces, O moves into blood vessels while CO out air. Lung diseases can impair airflow and reduce number of in lungs, making it harder to take eliminate . These changes contribute symptoms like breathlessness. The relationship between flow is called V/Q, where V ventilation—...
