BACKGROUND: Prior trials comparing a strategy of optimal medical therapy with or without revascularization have not shown that revascularization reduces cardiovascular events in patients with stable ischemic heart disease (SIHD). However, those trials only included participants in whom coronary anatomy was known prior to randomization and did not include sufficient numbers of participants with significant ischemia. It remains unknown whether a routine invasive approach offers incremental value over a conservative approach with catheterization reserved for failure of medical therapy in patients with moderate or severe ischemia...

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality, with exacerbations contributing strongly to the overall severity and burden of disease at the individual level. Many patients with COPD are managed predominantly in the primary care setting; therefore, primary care physicians (PCPs) must have awareness and understanding of the causes, effects, and management of exacerbations in COPD. This review offers practical information regarding how exacerbations are defined in the treatment setting, pathogenic and environmental causes, options for exacerbation treatment and prevention, and suggestions for improving care in the clinic...

Angiotensin II (ANG II) might play an important role in the co-effects of cold stress and fine particulate matter (PM2.5 ) on chronic obstructive pulmonary disease (COPD). The purpose of this study is to evaluate the roles of valsartan in alleviating COPD following co-exposure to cold stress and PM2.5 . Both the two intervention factors are carried out upon COPD rats with the intervention of valsartan. Blockade of angiotensin receptor by valsartan decreases the levels of malondialdehyde in the normal temperature and tumor necrosis factor-α under cold stress significantly...

Experimental models are critical for the understanding of lung health and disease and are indispensable for drug development. However, the pathogenetic and clinical relevance of the models is often unclear. Further, the use of animals in biomedical research is controversial from an ethical perspective.The objective of this task force was to issue a statement with research recommendations about lung disease models by facilitating in-depth discussions between respiratory scientists, and to provide an overview of the literature on the available models...

Chronic Obstructive Pulmonary Disease (COPD) is a syndrome caused by damage to the lungs resulting in decreased pulmonary function and reduced structural integrity. Pulmonary function testing (PFT) is currently used to diagnose and stratify COPD into severity groups and chest computed tomography (CT) imaging is often used to assess structural changes in the lungs. We hypothesized that the combination of PFT and CT phenotypes would provide a more powerful tool for assessing underlying morphologic differences associated with pulmonary function in COPD than PFT alone...

OBJECTIVES: Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) is recognized increasingly as a distinct clinical entity and is associated with higher comorbidities compared with patients with asthma and COPD alone. Little is known about the leading causes of death related to ACO in the US general population, however. Our aim was to define the causes of mortality among patients with ACO compared with asthma and COPD in the US population. METHODS: We examined questions using the National Health and Nutrition Examination Survey III database linked to the National Death Index...

Hyperphosphatemia has been associated with increased mortality in chronic kidney disease but the nature of such a relation in the general population is unclear. To investigate the association between phosphate (P) levels and all-cause and cause-specific mortality, we assessed two cohorts from the Rotterdam Study, with follow-up of 14.5 (RS-I) and 10.9 (RS-II) years until January 2012 with availability of fasting phosphate levels. Deaths were classified according to International Classification of Diseases into 7 groups: cardiovascular, cancer, infections, external, dementia, chronic lung diseases and other causes...

Plethysmographic alveolar pressure-flow ( P alv - F ) loops contain potentially relevant information about the pathophysiology of chronic obstructive pulmonary disease (COPD), but no quantitative analysis of these loops during spontaneous breathing has ever been performed. The area of the loop's inspiratory ( A ins ) and expiratory portion ( A exp ), and the difference between the end-expiratory and end-inspiratory alveolar pressure (Δ P alv ) were measured in 20 young, 20 elderly healthy subjects, and 130 stable COPD patients...

Aberrant activation of hypoxia-inducible factor (HIF)-1α is frequently encountered and promotes oxidative stress and inflammation in chronic obstructive pulmonary disease (COPD). The present study investigated whether sodium tanshinone IIA sulfonate (STS), a water-soluble derivative of tanshinone IIA, can mediate its effect through inhibiting HIF-1α-induced oxidative stress and inflammation in cigarette smoke (CS)-induced COPD in mice. Here, we found that STS improved pulmonary function, ameliorated emphysema and decreased the infiltration of inflammatory cells in the lungs of CS-exposed mice...

Background: Airway remodeling is an important feature of chronic obstructive pulmonary disease (COPD) that is associated with disease severity and irreversible airflow limitation. An extensive alteration of the extracellular matrix (ECM) surrounding the airway smooth muscle (ASM) bundle is one of the pathological manifestations of airway remodeling, which contributes to the decline in lung function. Tiotropium, a long-acting inhaled muscarinic receptor antagonist, has been confirmed to play a role in preventing airway remodeling including ECM deposition beyond bronchodilation in vivo, but the relationship between ASM cell (ASMC) relaxation and ECM production remains unclear...

BACKGROUND: Up to 70% of lung cancer survivors are affected by chronic obstructive pulmonary disease (COPD), a common, debilitating, comorbid disease. Lung cancer and COPD are both characterized by symptoms such as breathlessness, fatigue, and psychological distress. These distressing chronic symptoms are exacerbated by stress and detract from an individual's quality of life. OBJECTIVE: The aim of this study was to identify and evaluate evidence-based, commercially available apps for promoting mindfulness-based strategies among adults with a COPD or lung cancer history (ie, chronic lung disease)...

BACKGROUND: Detection of surfactant proteins A and D (SP-A and SP-D) in the serum of patients with pulmonary diseases is thought to reflect an injury of the alveolar epithelial barrier and as such serve as a biomarker for these diseases. However, the data for SP-B are limited. OBJECTIVES: The aim of this feasibility study was to assess whether immature SP-B pre-proteins might have value as a possible biomarker for pulmonary diseases. METHODS: In serum samples from patients with different chronic lung diseases (interstitial lung diseases [ILDs], chronic obstructive pulmonary disease, asthma, lung cancer, pulmonary hypertension, inflammation, patients on ventilator support; total n = 283), C-proSP-B was measured using an electrochemiluminescence immunoassay based on mouse monoclonal anti-C-proSP-B antibodies...

The mechanisms of controlling airway smooth muscle (ASM) tone are of utmost clinical importance as inappropriate constriction is a hallmark in asthma and chronic obstructive pulmonary disease. Receptors for acetylcholine and serotonin, two relevant mediators in this context, appear to be incorporated in specialized, cholesterol-rich domains of the plasma membrane, termed caveolae due to their invaginated shape. The structural protein caveolin-1 partly accounts for anchoring of these receptors. We here determined the role of the other major caveolar protein, caveolin-3 (cav-3), in orchestrating cholinergic and serotonergic ASM responses, utilizing newly generated cav-3 deficient mice...

BACKGROUND: Pulmonary vascular remodeling is an angiogenic-related process involving changes in smooth muscle cell (SMC) homeostasis, which is frequently observed in chronic obstructive pulmonary disease (COPD). MicroRNAs (miRNAs) are small non-coding RNAs that regulate mRNA expression levels of many genes leading to the manifestation of cell identity and specific cellular phenotypes. Here we evaluate the miRNA expression profiles of pulmonary arteries (PA) of patients with COPD and its relationship with the regulation of SMC phenotypic change...

Introduction: Exposure to secondhand smoke (SHS) is associated with occult obstructive lung disease as evident by abnormal airflow indices representing small airway disease despite having preserved spirometry (normal forced expiratory volume in 1 s-to-forced vital capacity ratio, FEV1 /FVC). The significance of lung volumes that reflect air trapping in the presence of preserved spirometry is unclear. Methods: To investigate whether lung volumes representing air trapping could determine susceptibility to respiratory morbidity in people with SHS exposure but without spirometric chronic obstructive pulmonary disease, we examined a cohort of 256 subjects with prolonged occupational SHS exposure and preserved spirometry...
