This study aims to elucidate the change in pulmonary function in stage 0 COPD patients. A total of 48 stage 0 COPD patients and 46 healthy adults were included in the study. The status of their pulmonary function was determined by an impulse oscillometry (IOS) system, and the spirometric indexes such as forced vital capacity, maximum expiratory flow-volume (MEFV) curve, total respiratory impeda...
Background: Pesticides are chemical compounds used against vectors of human and animal diseases as well as plant pests. This study was undertaken to assess pulmonary reactions, if any, associated with occupational exposure to pesticides. Methods: This was a cross sectional analytical study in which a group of 86 exposed (employees of a pesticide producing company) and 75 unexposed referent sub...
Background and Objectives: Pulmonary consequences of exposure to low concentrations of ammonia have been less studied. The purpose of this study was to model the pulmonary consequences of exposure to low concentrations of ammonia. Methods: This historical cohort study was conducted in the fertilizer industries in 2019. The participants were divided into two groups of exposed (n=98) and non-...
asthma management is a major concern because some asthmatic patients either do not respond or else hardly respond to treatment. therefore in the present study, an attempt has been made to determine the predictors of treatment response in asthmatic patients. thirty six asthmatic adults including 13 male and 23 female were studied dur¬ing a 3 month treatment period. asthma symptom score (ss) and ...
background fumes released form welding activities are capable of initiating several acute and chronic respiratory effects. objectives the aim of the present study was to evaluate respiratory symptoms and spirometry parameters in welders of a steel industry. methods this cross-sectional study was conducted in a steel industry and involved 60 welders and 40 non-welders. a questionnaire was used t...
abstract Introduction: Spirometry is a common device screening in occupational pulmonary disease. Dental laboratory workers usually are exposed to vapor, toxic gases, dust, metallic alloys, acrylics, and stones. Aim of This study was a Spirometric evaluation of the pulmonary function of Yazd’s dental laboratory workers. Method and materials: in this cross-sectional study 37 Yazd’dental tech...
Background: The occupational exposure conditions such as dust concentration, exposure time, smoking status and use of respiratory protection device are effective on pulmonary function disorder. The aim of this study was to determine the risk of pulmonary function disorder in the workers exposed to silica dust in the stone crushing by using Cox regression model. Method: 117 of workers employ...
Abstract Background: Tile workers are exposed to a lot of dusts and are susceptible to various pulmonary complications. This study was designed to evaluate the respiratory symptoms and lung capacities of tile workers. Methods: This was a retrospective, cross sectional study on 350 workers in different factory workshops. We assessed respiratory complaints and pulmonary function tests. Data wer...
Introduction: Metabolic syndrome (MetS) and impaired lung functions have been associated with an increased risk for coronary heart disease. The aim of this study was to investigate the pulmonary functions in patients with MetS. Methods: This cross-sectional study included 200 subjects with MetS in the study group and 100 subjects without MetS in the control group. Participants were examined...
Thoracic surgery remains the better therapeutic option for non-small cell lung cancer patients that are diagnosed in early stage disease. Preoperative lung function assessment includes respiratory function tests (RFT) and cardio-pulmonary exercise testing (CPET). Vo2 peak, FEV1 and DLCO as well as recognition of performance status, presence of co-morbidities, frailty indexes, and age predict th...
