Chronic obstructive pulmonary disease (COPD) is commonly associated with multiple comorbidities. Our objective was to assess the prevalence of comorbidities in patients with COPD and to relate their prevalence to the severity of the disease by using a large German health care database. Based on the retrospective analysis of a two-year (2013-2014) database from the German Statutory Health Insurance system, we obtained a representative sample of 4,075,493 german insurants. This sample included 146,141 patients with COPD (age: ≥35 years)...

Studies suggest that long-term chronic exposure to fine particulate matter air pollution can increase lung cancer mortality. We analyzed the association between long term PM2.5 and ozone exposure and mortality due to lung cancer, ischemic heart disease, and chronic obstructive pulmonary disease, accounting for geographic location, socioeconomic status, and residential mobility. Subjects in the 1991 Canadian Census Health and Environment Cohort (CanCHEC) were followed for 20years, and assigned to regions across Canada based on spatial synoptic classification weather types...

PURPOSE OF REVIEW: Lung transplantation offers an effective treatment modality for patients with end-stage chronic obstructive pulmonary disease (COPD). The exact determination of when to refer, list, and offer transplant as well as the preferred transplant procedure type remains unclear. Additionally, there are special considerations specific to patients with COPD being considered for lung transplantation, including the implications of single lung transplantation on lung cancer risk, native lung hyperinflation, and overall survival...

RATIONALE: Up to 40% of smokers develop chronic obstructive pulmonary disease (COPD) over a period that spans decades. Despite the importance of COPD, much remains to be learned about susceptibility and pathogenesis, especially during early, pre-diagnostic stages of disease. Airway basal progenitor cells are crucial for lung health and resilience, because of their ability to repair injured airways. In COPD, the normal airway epithelium is replaced with increased basal and secretory (mucous) cells and decreased ciliated cells, suggesting that progenitors are impaired...

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) is a well established risk factor for lung cancer. Newer studies reveal a myriad of other mechanisms, some proven and some putative, which may contribute to their association. RECENT FINDINGS: There is an ever-growing bundle of evidence that suggests a close association between persistent chronic inflammation and lung cancer. A few potential targets of genetic susceptibility locus for COPD and lung cancer have been suggested...

OBJECTIVES: Non-small cell lung cancer (NSCLC) and chronic obstructive pulmonary disease (COPD) have been proposed to have a mutual developmental mechanism, but their association has not been fully understood. We aimed to examine the association of the mutational landscape of NSCLC with co-morbid COPD. MATERIALS AND METHODS: A total of 197 surgical specimens of early stage NSCLC were retrospectively collected from two independent sources, namely, the Japan Molecular Epidemiology for Lung Cancer Study and the Osaka City University Hospital cohort from 2010 to 2013...

BACKGROUND: Recently, it was shown that chronic tobacco smoking evokes specific cellular and molecular changes in white blood cells by an excess of G protein-coupled receptor 15 (GPR15)-expressing T cells as well as a hypomethylation at DNA CpG site cg05575921 in granulocytes. In the present study, we aimed to clarify the general usefulness of these two biomarkers as putative signs of non-cancerous change in homeostasis of the lungs. METHODS: In a clinical cohort consisting of 42 patients with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and pneumonia and a control cohort of 123 volunteers, the content of GPR15-expressing blood cells as well as the degree of methylation at cg05575921 were analysed by flow-cytometry and pyrosequencing, respectively...

The role of infectious agents in the etiology of inflammatory diseases once believed to be non-infectious is increasingly being recognized. Many bacterial components in the indoor dust can evoke inflammatory lung diseases. Bacteria secrete nanometer-sized vesicles into the extracellular milieu, so-called extracellular vesicles (EVs). which are pathophysiologically related to inflammatory diseases. Microbiota compositions in the indoor dust revealed the presence of both gram-negative and gram-positive bacteria...

Aging is a major risk factor for the development of chronic lung diseases such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and lung cancer. A main aspect of aging is the impaired function of maintaining homeostasis in the organs and body, which is associated with cellular senescence. Cellular senescence is recognized as the state of irreversible cell cycle arrest in response to a variety of cellular stresses. Senescent cells are not simply cell cycle-arrested cells; they also affect bystander cells through the secretion of bioactive molecules, termed the senescence-associated secretory phenotype (SASP)...

INTRODUCTION: Surgery is the standard curative treatment for lung cancer but is only possible in patients with local tumour and preserved exercise capacity. Improving fitness before surgery can reduce postoperative complications and mortality. However, preoperative rehabilitation remains difficult to implement for several reasons. We aim to investigate the effectiveness of an intensive 3-week home-based preoperative exercise training programme on hospital discharge ability, postoperative complications and physical performance in patients with chronic obstructive pulmonary disease (COPD) who are eligible for lung cancer surgery...

Movement is the basic attribute of life. It is not surprising that the return to regular physical activity is a very effective and cheap means of preventing and treating most non-cummunicable diseases. Therefore, every physician should be able to prescribe a suitable physical activity. The minimum amount of physical activity with proven effects in primary prevention of chronic diseases is relatively low: 150 minutes of moderate physical activity or 75 minutes of high intensity exercise per week or a combination of the two...

Cannabis use increased sharply from 2010 to 2014 in France. Cannabis is often consumed with tobacco, although the use of marijuana is developing. Tobacco and cannabis smoke have many common characteristics in terms of irritants, carcinogens and carbon monoxide. They also differentiate by their dependence mechanisms, with nicotine and its receptors for tobacco and tetra-hydro-cannabinol (THC) and its specific receptors for cannabis. Chronic inhalation (700,000 daily users in France) over a long period most likely increases the relative risk of bronchial cancer...

Persistent air leak (PAL) is associated with significant morbidity and mortality, prolonged hospitalization and increased health-care costs. It can arise from a number of conditions, including pneumothorax, necrotizing infection, trauma, malignancies, procedural interventions and complications after thoracic surgery. Numerous therapeutic options, including noninvasive and invasive techniques, are available to treat PALs. Recently, endobronchial one-way valves have been used to treat PAL. We conducted a systematic review based on studies retrieved from PubMed, EMbase and Cochrane library...

Lung cancer and chronic obstructive pulmonary disease (COPD) are both serious threats to human health, resulting in a heavy economic burden for the society. Epidemiological studies have shown that lung cancer and COPD have a high comorbid rate. Cigarette smoking is a congenerous risk factor for both lung cancer and COPD, and may lead to these diseases by triggering certain similar pathways. The common pathogenesis of lung cancer and chronic obstructive pulmonary disease involves premature pulmonary failure, oxidative stress and inflammation, telomere length, genetic susceptibility, and epigenetics...
