The occupational contribution to chronic obstructive pulmonary disease (COPD) has yet to be put in a global perspective. In the present study, an ecological approach to this question was used, analysing group-level data from 90 sex-specific strata from 45 sites of the Burden of Obstructive Lung Disease study, the Latin American Project for the Investigation of Obstructive Lung Disease and the E...

Zielsetzung Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of death worldwide, yet early detection and treatment can prevent the progression disease. X-ray Computed Tomography (CT) scans chest provide quantitative measure morphological changes in lung. The potential incorporating optimal Window Setting (WS) selection, typically carried out during examination CT for COPD, genera...

Objective: This article systematically reviews the efficacy and safety of TCM Intestinal Cleansing Method in treatment acute exacerbation chronic pulmonary obstructive disease, provides clinical reference for disease. Methods: A computer search major databases such as China Knowledge Network (CNKI), VIP, WanFang, CBM, PubMed, Embase, Cochrane (January 1995-July 2022) was conducted to collect re...

background: chronic obstructive pulmonary disease (copd) is a chronic respiratory disease, which reduces the lung function and causes respiratory symptoms over time, and it is primarily associated with shortness of breath, cough and sputum production. roflumilast, which is a long-acting selective inhibitor, reduces the anti-inflammatory effect of the main symptoms of copd. the aim of this study...

The physiological hallmark of chronic obstructive pulmonary disease (COPD) is expiratory flow limitation. However, it is the resultant air trapping and associated increases in lung volume (hyperinflation) that provide a mechanistic link between the physiological impairment and the characteristic symptoms of COPD, such as dyspnoea (breathlessness), exercise intolerance and reduced health-related...

BACKGROUND Negative pressure ventilation provides intermittent non-invasive ventilatory assistance for patients with advanced chronic obstructive lung disease. Upper airway obstruction during sleep, a reported complication of the technique, may, however, limit its clinical applicability. METHODS The effects of nocturnal negative pressure ventilation on ventilation and on indices of sleep qual...

To determine whether airway receptors are responsible for the rapid, shallow breathing pattern seen in hypercapnic chronic obstructive lung disease, 10 patients underwent upper airway anaesthesia with inhaled lignocaine in a placebo controlled study. There was a significant reduction in breathing frequency after lignocaine (p less than 0.001) that was due to an increase in expiratory time (p le...

INTRODUCTION Chronic obstructive pulmonary disease is estimated to become the fifth leading cause of death worldwide by 2020. The mortality and morbidity from chronic obstructive pulmonary disease is getting higher and higher as a result of the epidemics in tobacco consumption all over the world, especially in developing countries. The study objectives were to determine the correlation between ...
