The natural disease course of chronic obstructive pulmonary disease (COPD) is often punctuated by exacerbations: acute events of symptom worsening associated with significant morbidity and healthcare resource utilization; reduced quality of life; and increased risk of hospitalization and death. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommend that patients at risk of exacerbations (GOLD Groups C and D) receive a long-acting muscarinic antagonist (LAMA) or a long-acting β2-agonist (LABA)/LAMA combination, respectively, as preferred initial treatments...

Successful pregnancy requires an appropriate communication between the mother and the embryo. Recently, exosomes and microvesicles, both membrane-bound extracellular vesicles (EVs) present in the oviduct fluid have been proposed as key modulators of this unique cross-talk. However, little is known about their content and their role during oviduct-embryo dialogue. Given the known differences in secretions by in vivo and in vitro oviduct epithelial cells (OEC), we aimed at deciphering the oviduct EVs protein content from both sources...

INTRODUCTION: The superiority of tiotropium/olodaterol is demonstrated in improvement of lung function, dyspnea, lung hyperinflation, and quality of life compared with either monotherapy in patients with chronic obstructive pulmonary disease (COPD). Japanese Respiratory Society Guidelines for COPD management include improvement of exercise tolerance and daily physical activity as the treatment goals; however, there is limited evidence in Japanese patients with COPD. METHODS: A protocol is developed for the VESUTO(®) study that investigates the efficacy of tiotropium/olodaterol fixed-dose combination (FDC) compared with tiotropium alone on inspiratory capacity (IC, volume from functional residual capacity to total lung capacity), exercise capacity, and daily physical activity in Japanese patients with COPD...

The cardiovascular risk of concurrently using long-acting β2-agonists (LABAs) and anticholinergics (LAMAs) in COPD is uncertain. We assessed the comparative cardiovascular and cerebrovascular safety of adding a second long-acting bronchodilator in patients with COPD.We identified a cohort of COPD patients, new users of LABA or the LAMA tiotropium during 2002-2012, from the UK Clinical Practice Research Datalink. Using high-dimensional propensity scores, each patient adding a second bronchodilator was matched with a patient who remained on monotherapy...

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by pathophysiological factors including airflow limitation, hyperinflation and reduced gas exchange. Treatment consists of lifestyle changes, lung rehabilitation and pharmacological therapies such as long acting beta-2-agonists (LABA) and long acting muscarinic antagonists (LAMA). More recently bronchoscopic treatments are emerging for COPD. Among them endobronchial valves(EBV) and endobronchial coils (EBC), next to endobronchial stents, sclerosing agents, targeted lung denervation and liquid nitrogen metered cryospray...

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity, mortality and health care expenditure throughout the world. COPD guidelines recommend the use of long-acting muscarinic antagonist (LAMA) either alone or in combination with a long-acting β2 agonist (LABA). For over 10 years, tiotropium was the only LAMA that was used in the management of COPD. Over the past few years, various new drugs have been identified that act on the muscarinic receptors and β2 receptors. Umeclidinium (Umec) is a new LAMA currently approved for use in patients with COPD either as monotherapy or in combination with vilanterol (Vil)...

BACKGROUND: The addition of long-acting beta2-agonists (LABAs) to corticosteroids improves asthma control. Cigarette smoke exposure, increasing oxidative stress, may negatively affect corticosteroid responses. The anti-inflammatory effects of formoterol (FO) and fluticasone propionate (FP) in human bronchial epithelial cells exposed to cigarette smoke extracts (CSE) are unknown. AIMS: This study explored whether FP, alone and in combination with FO, in human bronchial epithelial cellline (16-HBE) and primary bronchial epithelial cells (NHBE), counteracted some CSE-mediated effects and in particular some of the molecular mechanisms of corticosteroid resistance...

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally and incidence rates are continuing to rise. Long-acting bronchodilators are the foundation on which current pharmacological approaches to COPD management are built, with long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs) recommended across the spectrum of the disease continuum. Combining LAMAs and LABAs provides additional lung function improvements and relief of patient symptoms compared with either therapy alone...

BACKGROUND: Despite its proven efficacy in improving symptoms and reducing exacerbations, many patients with asthma are not fully adherent to their steroid inhaler. Suboptimal adherence leads to poorer clinical outcomes and increased health service utilisation, and has been identified as a contributing factor to a third of asthma deaths in the UK. Reasons for non-adherence vary, and a variety of interventions have been proposed to help people improve treatment adherence. OBJECTIVES: To assess the efficacy and safety of interventions intended to improve adherence to inhaled corticosteroids among people with asthma...
