dust can be produced by almost all production processes in portland cement factory. dust exposure potentially can affect respiratory function. but evidence for respiratory effect of cement dust exposure has not been conclusive. in this study we assessed effect of cement dust exposure on respiratory function in a cement production factory. a respiratory symptoms questionnaire was completed and p...

Respiratory impairment results from primary disease of the lungs / airways or from impairment of the respiratory muscles. The proper identification of the respiratory impairment allows for proper management to decrease morbidity and mortality. Patients with neuromuscular impairment typically have hypoventilation or ventilator insufficiency/failure resulting in hypercapnia, hypoxia and an ineffe...

BACKGROUND Bulbar weakness and respiratory impairment have been associated with increased morbidity in retrospective studies of Guillain-Barré syndrome (GBS) patients. The aim of this study was to prospectively explore the relationship between subclinical swallowing impairment, respiratory function parameters, the necessity to intubate patients and the development of early postintubation pneumo...

BACKGROUND Among older persons, within the clinical context of respiratory symptoms and mobility, evidence suggests that improvements are warranted regarding the current approach for identifying respiratory impairment (ie, a reduction in pulmonary function). METHODS Among 3583 white participants aged 65 to 80 years (Cardiovascular Health Study), we calculated the prevalence of respiratory imp...

OBJECTIVE Spirometric Z scores by lambda-mu-sigma (LMS) rigorously account for age-related changes in lung function. Recently, the Global Lung Function Initiative (GLI) expanded LMS spirometric Z scores to multiple ethnicities. Hence, in aging populations, the GLI provides an opportunity to rigorously evaluate ethnic differences in respiratory impairment, including airflow limitation and restri...

Objectives: Myotonic dystrophy type 1 (DM1) is characterized by multisystemic effects that include frequent respiratory impairment that can affect prognosis. Despite this, there are not many studies specifically evaluating such alterations and no one from Spain. The aim of this study is to evaluate respiratory impairment in a Spanish group of patients with DM1. Materials and methods: Respirator...

BACKGROUND COPD is a major cause of disability, but little is known about how disability develops in this condition. METHODS The authors analysed data from the Function, Living, Outcomes and Work (FLOW) Study which enrolled 1202 Kaiser Permanente Northern California members with COPD at baseline and re-evaluated 1051 subjects at 2-year follow-up. The authors tested the specific hypothesis tha...

Myotonic dystrophy (DM1) is a multisystemic disease caused by an expansion of CTG repeats in the region of DMPK, the gene encoding DM protein kinase. The severity of muscle disability in DM1 correlates with the size of CTG expansion. As respiratory failure is one of the main causes of death in DM1, we investigated the correlation between respiratory impairment and size of the (CTG)n repeat in D...
