Chronic Obstructive Pulmonary Disease (COPD) is the third leading cause of morbidity and death and imposes major socioeconomic burdens globally. It is a progressive and disabling condition that severely impairs breathing and lung function. There is a lack of effective treatments for COPD, which is a direct consequence of the poor understanding of the underlying mechanisms involved in driving the pathogenesis of the disease. Toll-like receptor (TLR)2 and TLR4 are implicated in chronic respiratory diseases, including COPD, asthma and pulmonary fibrosis...

Phillip W Clapp, Ilona Jaspers
PURPOSE OF REVIEW: Vaping is gaining popularity in the USA, particularly among teens and young adults. While e-cigs are commonly represented as safer alternatives to tobacco cigarettes, little is known regarding the health effects of their short- or long-term use, especially in individuals with pre-existing respiratory diseases such as asthma. Flavored e-cig liquids (e-liquids) and e-cig aerosols contain airway irritants and toxicants that have been implicated in the pathogenesis and worsening of lung diseases...

Noncommunicable diseases (NCDs) are a major and increasing global health issue. The World Health Organization (WHO) estimates that NCDs represent 63% of all global deaths of which 3.9 million are due to chronic respiratory diseases (CRDs) and Chronic Obstructive Pulmonary Disease (COPD) in particular. COPD is now the third most common cause of death globally; 90% of these deaths occur in Low and Middle Income Countries (LMICs). COPD affects 329 million people, almost 5% of the world's population. In addition, asthma affects 334 million people, again representing almost 5% of the world's population...

Asthma-COPD overlap syndrome (ACOS) or asthma-COPD overlap captures the subset of patients with airways disease who have features of both asthma and chronic obstructive pulmonary disease (COPD). Although definitions of ACOS vary, it is generally thought to encompass persistent airflow limitation in a patient older than 40 years of age with either a history of asthma or large bronchodilator reversibility. ACOS affects about a quarter of patients with COPD and almost a third of patients who previously had asthma...

BACKGROUND: Reduction of 30-day readmissions in patients hospitalized for chronic obstructive pulmonary disease (COPD) is a national objective. However, there is a dearth of research on sex and racial/ethnic differences in the reason for 30-day readmission. METHODS: We conducted a retrospective cohort study using 2006-2012 data from the State Inpatient Database of eight geographically-diverse US states (Arkansas, California, Florida, Iowa, Nebraska, New York, Utah, and Washington)...

INTRODUCTION: The long-acting muscarinic antagonist, umeclidinium (UMEC), combined with the inhaled corticosteroid, fluticasone furoate (FF), improves lung function in symptomatic patients with asthma. We assessed FF/UMEC in patients with a primary diagnosis of asthma or chronic obstructive pulmonary disease (COPD), but physiological characteristics of both (fixed airflow obstruction and reversibility to salbutamol). METHODS: This double-blind, parallel-arm, 3-phase study randomised 338 patients (1:1:1:1:2:2) to FF 100 mcg alone or combined with UMEC (15...

Tele-medicine is a clinical application connecting a patient with specialized care consultants by means of electronic platforms, potentially able to improve patients' self-management and allow for the care of patients with limited access to health services. This article summarizes the use of tele-medicine as a tool in managing patients suffering from some pathological respiratory conditions. Areas covered: We searched papers published between 1990 and 2017 dealing with tele-medicine and respiratory diseases, chronic obstructive pulmonary disease, asthma, interstitial lung disease, chronic respiratory failure, neuromuscular diseases, critical illness, home mechanical ventilation, and also legal and economic issues...

BACKGROUND: Pulmonary conditions such as asthma and chronic obstructive pulmonary disease (COPD) are common conditions that warrant special consideration in the perioperative period. When these patients undergo surgical interventions, they have risk of complications such as bronchospasm, hypoxia, and even postoperative respiratory failure that warrants unplanned intensive care unit admission. Thus, clinicians must be familiar with pulmonary medication regimens that are critical for maintaining stable homeostasis of these chronic conditions...

Hundreds of millions of people suffer from asthma and chronic obstructive pulmonary disease (COPD) worldwide. Current medications to control these chronic respiratory diseases can be administered using inhaler devices, such as the pressurized metered dose inhaler (pMDI) and dry powder inhaler (DPI). Providing that they are used as prescribed, inhalers can improve patients' clinical outcomes and quality of life. Poor patient inhaler adherence (both time of use and user technique) is, however, a major clinical concern and is associated with poor disease control, increased hospital admissions and increased mortality rates, particularly in low-middle income countries...

Chronic obstructive pulmonary disease risk is lower in black and south Asian people than white people, when adjusting for age, sex, deprivation and smoking status. The role of smoking intensity was assessed for its contribution to ethnic differences in chronic obstructive pulmonary disease risk, a relationship not previously investigated. This cross-sectional study included routinely collected primary care data from four multi-ethnic London boroughs. Smoking intensity (estimated by cigarettes per day) was compared between ethnic groups...

INTRODUCTION: The airway epithelium is a physical and immunological barrier that protects the pulmonary system from inhaled environmental insults. Uric acid has been detected in the respiratory tract and can function as an antioxidant or damage associated molecular pattern. We have demonstrated that human airway epithelial cells are a source of uric acid. Our hypothesis is that uric acid production by airway epithelial cells is induced by environmental stimuli associated with chronic respiratory diseases...

BACKGROUND AND AIM: Early detection of COPD may reduce the future burden of the disease. We aimed to investigate whether prescreening with a COPD-6 screening device (measuring FEV1 and FEV6) facilitates early detection of COPD in primary care. METHODS: In primary care, individuals at high risk of COPD (ie, age ≥35 years, relevant exposure, and at least one respiratory symptom) and no previous diagnosis of obstructive lung disease were examined with a COPD-6 screening device...

Omics approaches are high-throughput unbiased technologies that provide snapshots of various aspects of biological systems and include: 1) genomics, the measure of DNA variation; 2) transcriptomics, the measure of RNA expression; 3) epigenomics, the measure of DNA alterations not involving sequence variation that influence RNA expression; 4) proteomics, the measure of protein expression or its chemical modifications; and 5) metabolomics, the measure of metabolite levels. Our understanding of pulmonary diseases has increased as a result of applying these omics approaches to characterize patients, uncover mechanisms underlying drug responsiveness, and identify effects of environmental exposures and interventions...

Respiratory disorders are common among people with intellectual disabilities (ID). However, few studies have investigated these disorders among older people with ID. We identified 7936 people, aged 55+ years, with ID and a reference cohort from the general population. Data on diagnoses of chronic respiratory disorders, with a focus on asthma and chronic obstructive pulmonary disease (COPD), were collected, as was information on health care visits due to such disorders. We also added data on the prescription of drugs for obstructive airway diseases...
