BACKGROUND The consequences of chronic obstructive pulmonary disease (COPD) on daily life, encapsulated by the term "health-related quality of life" (HRQL), are important in determining appropriate home care. There is a need to understand the relative contribution of respiratory impairment, physical disability, coping, age, and socioeconomic variables on HRQL. METHODS Patients with COPD were ...

The effect of occupational exposure to local powdered tobacco (snuff) on pulmonary function was studied. Snuff industry workers in Onitsha and Enugu markets were studied and compared with age, weight, and height-matched control not exposed to any known air pollutant. The pulmonary indices studied include forced vital capacity [FVC], forced expiratory volume in one second [FEV1] and ratio of FEV...

Welding is one of the key components of numerous manufacturing industries, which has potential physical and chemical health hazards. Many components of welding fumes can potentially affect the lung function. This study investigates the effects of welding fumes on lung function and respiratory symptoms among welders of an automobile manufacturing plant in Iran. This historical cohort study asses...

Alpha-1-antitrypsin deficiency (AATD), also known as alpha1-proteinase inhibitor deficiency, is an autosomal co-dominant condition. The genotypes associated with AATD include null, deficient, and dysfunctional alpha-1-antitrypsin (A1AT) variants, which result in low levels of circulating functional A1AT, unbalanced protease activity, and an increased risk of developing lung emphysema, the leadi...

Aging is the progressive loss of cellular function which inevitably leads to death. Failure of proteostasis including the decrease in proteasome function is one hallmark of aging. In the lung, proteasome activity was shown to be impaired in age-related diseases such as chronic obstructive pulmonary disease. However, little is known on proteasome function during healthy aging. Here, we comprehen...

Hajari Case A, Johnson P. BMJ Open Resp Res 2017;4:e000192. doi:10.1136/bmjresp-2017-000192 AbstrAct Idiopathic pulmonary fibrosis (IPF) is a rare lung disease characterised by progressive loss of lung function, dyspnoea and cough. IPF has a variable clinical course but a poor prognosis. Nintedanib, a tyrosine kinase inhibitor, is one of two drugs approved for the treatment of IPF. In clinical ...

to identify and describe factors relating to quality of life (qol) for subjects with low vision and blindness in iran's sistan-baluchestan province, this research designed. this cross sectional study was done on subjects with vision disability who randomly selected and covered by the zahedan welfare organization, zahedan, iran. evaluations were made for the following factors related to visual i...

 Abstract Background: Pulmonary involvement in ulcerative colitis (UC) is thought to be rare. There is not a definite document about the question that "Is the lung a target organ in inflammatory bowel disease?" The aim of the present study is to compare lung function between cases with UC and healthy controls. This study will also be of interest about searching the outbreak of pulmonary functio...

Environmental pollutants, such as dioxins and furans, are extremely toxic and related with pulmonary diseases development. Impairment of mitochondrial function has been shown in pollutant-induced hepatic injury, but it has not been addressed in lungs, even though lung mitochondria are primary cellular targets for pollutants-induced toxicity. In isolated lung mitochondria, dibenzofuran significa...
