Protein misfolding within the endoplasmic reticulum (ER stress) can be a cause or consequence of pulmonary disease. Mutation of proteins restricted to the alveolar type II pneumocyte can lead to inherited forms of pulmonary fibrosis, but even sporadic cases of pulmonary fibrosis appear to be strongly associated with activation of the unfolded protein response (UPR) and/or the integrated stress response (ISR). Inhalation of smoke can impair protein folding and may be an important cause of pulmonary ER stress...

A previously healthy 55-year-old woman presented with worsening dyspnoea on exertion. The patient lived at altitude, did not smoke and had no exposure to occupational or environmental toxins. Her physical examination, including pulmonary, was unremarkable. Pulmonary function tests showed forced expiratory volume in 1 s/forced vital capacity ratio 74% predicted, diffusing capacity for carbon monoxide (DLCO) 92% predicted and residual volume 213% predicted. Rheumatological workup was negative. Chest radiograph showed hyperinflation without consolidation, and high-resolution chest CT showed mosaic attenuation with air trapping on expiratory imaging...

Cigarette smoking (CS) is a principal contributor to a spectrum of devastating lung diseases whose occurrence and severity may vary between individuals and not appear for decades after prolonged use. One explanation for the variability and delay in disease onset is that nicotine, the addictive component of CS, acts through the ionotropic nicotinic acetylcholine receptor (nAChR) alpha7 (α7) to modulate anti-inflammatory protection. In this study we measured the impact α7 signaling has on the mouse distal lung response to side-stream CS exposure for mice of the control genotype (α7G) and those in which the α7-receptor signaling mechanisms are restricted by point mutation (α7E260A:G)...

BACKGROUND AND AIMS: No prospective study has investigated whether individuals with respiratory impairments, including chronic obstructive pulmonary disease (COPD) and restrictive lung disease (RLD), are at increased risk of abdominal aortic aneurysm (AAA). We aimed to prospectively investigate whether those respiratory impairments are associated with increased AAA risk. METHODS: In 1987-1989, the Atherosclerosis Risk in Communities (ARIC) study followed 14,269 participants aged 45-64 years, without a history of AAA surgery, through 2011...

BACKGROUND: The diagnosis of chronic obstructive pulmonary disease (COPD) is usually made based on history and physical exam alone. Symptoms of dyspnea, cough, and wheeze are nonspecific and attributable to a variety of diseases. Confirmatory testing to verify the airflow obstruction is available but rarely used, which may result in substantial misdiagnoses of COPD. The aim of this study is to evaluate the use of confirmatory testing and assess the accuracy of the diagnosis. METHODS: From January 2011 through December 2013, 6,018 patients with COPD as a principal or leading diagnosis were admitted at a community teaching hospital...

In 2005, the combined pulmonary fibrosis and emphysema (CPFE) was first defined as a distinct entity, which comprised centrilobular or paraseptal emphysema in the upper pulmonary lobes, and fibrosis in the lower lobes accompanied by reduced diffused capacity of the lungs for carbon monoxide (DLCO). Recently, the fibrosis associated with the connective tissue disease was also included in the diagnosis of CPFE, although the exposure to tobacco, coal, welding, agrochemical compounds, and tire manufacturing are the most frequent causative agents...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is one of 21st century. About 210 million people all over the world are suffering with COPD, and annually 3 million people die of it. Under the influence of different factors, such as smoking, air prolusion, evaporation of chemicals, poisoning effect of chemical firings, inflammation processes take place in lungs, and if it is prolonged and take place simultaneously with morphological changes in the lungs, it it provide the de4velopment of the systemic inflammation process...

Normal gas exchange after birth requires functional lung alveolar units that are lined with epithelial cells, parts of which are intricately fused with microvascular capillaries. A significant phase of alveolar lung development occurs in the perinatal period, continues throughout early stages in life, and requires activation of matrix-remodeling enzymes. Failure to achieve an optimum number of alveoli during lung maturation can cause several untoward medical consequences including disabling obstructive and/or restrictive lung diseases that limit physiological endurance and increase mortality...

The restrictive spirometric pattern is associated with a substantial morbidity and mortality burden. We sought to determine to what extent spirometric restriction is associated with impaired quality of life.We used data from two large population-based European cohorts: 6698 European Community Respiratory Health Survey (ECRHS) and 6069 Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA) adult participants. The restrictive pattern was defined as forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ≥lower limit of normal (LLN) and FVC <LLN; an obstructive pattern was defined as FEV1/FVC <LLN independent of FVC...

BACKGROUND Accumulating evidence shows that functional impairment in subjects with coal workers' pneumoconiosis (CWP) is principally due to emphysema and airflow obstruction, rather than underlying restrictive mechanisms. However, cigarette smoking has remained a major confounder. The aim of this study was to assess whether coal dust exposure was associated with emphysema and/or airflow obstruction in the absence of smoking history. MATERIAL AND METHODS The subjects evaluated for possible pneumoconiosis between 2013 and 2015 were retrospectively enrolled into this study...

Visceral leishmaniasis (VL) is associated with interstitial pneumonitis according to histology and radiology reports. However, studies to address the functional impact on respiratory function in patients are lacking. We assessed pulmonary function using noninvasive spirometry in a cross-sectional study of hospitalized adult VL patients from Minas Gerais, Brazil, without unrelated lung conditions or acute infections. Lung conditions were graded as normal, restrictive, obstructive, or mixed patterns, according to Brazilian consensus standards for spirometry...

Chronic obstructive pulmonary disease (COPD) is a devastating lung disorder characterized by sustained airway flow restriction that is not fully reversible. The precise pathogenic mechanisms are unknown, but it is clear that cigarette smoking and chronic inflammatory stimulation are the major causes of COPD. Lung inflammation associated with COPD involves multiple cytokines, aggregation, and activation of neutrophils in the airway and lung tissue, and release of proteases and oxygen free radicals. In this study, a rat model of COPD was established by daily cigarette smoke exposure plus endotoxin treatment (the experimental group)...

Background: Diabetes mellitus Type 1 (T1DM) is associated with metabolic and microvascular diseases as part of a multi-organ and multi-systemic disorder. The dense network of capillary vessels in the lungs may change during the course of the development of microangiopathy. The connective tissue as well as alveoli may be subjected to non-enzymatic glycosylation of proteins which may in turn affect pulmonary function. Previous studies investigating lung function in patients with type 1 diabetes have only been performed on small numbers of patients...

Asthma is the most prevalent chronic respiratory disease both in children and adults and resembles a complex syndrome rather than a single disease. Different methods have been developed to better characterise distinct asthma phenotypes in childhood and adulthood. In studies of adults, most phenotyping relies on biomaterials from the lower airways; however, this information is missing in paediatric studies because of restricted accessibility. Few patients show symptoms throughout childhood, adolescence, and adulthood...
