    Interspecies diversity of chloride channel regulators, calcium-activated 3 genes.
    PLoS One 2018 18;13(1):e0191512. Epub 2018 Jan 18.
    Department of Veterinary Pathology, Faculty of Veterinary Medicine, Freie Universität Berlin, Berlin, Germany.
    Members of the chloride channel regulators, calcium-activated (CLCA) family, have been implicated in diverse biomedical conditions, including chronic inflammatory airway diseases such as asthma, chronic obstructive pulmonary disease, and cystic fibrosis, the activation of macrophages, and the growth and metastatic spread of tumor cells. Several observations, however, could not be repeated across species boundaries and increasing evidence suggests that select CLCA genes are particularly prone to dynamic species-specific evolvements. Here, we systematically characterized structural and expressional differences of the CLCA3 gene across mammalian species, revealing a spectrum of gene duplications, e. Read More

    Estimation of inhalation flow profile using audio-based methods to assess inhaler medication adherence.

    Trinity Centre for Bioengineering, Trinity College Dublin, The University of Dublin, Dublin, Ireland.
    Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow parameters such as the peak inspiratory flow rate of inhalations, however, these methods required multiple calibration inhalation audio recordings.

    Addressing the Impact and Unmet Needs of Nonadherence in Asthma and Chronic Obstructive Pulmonary Disease: Where Do We Go From Here?
    J Allergy Clin Immunol Pract 2018 Jan 12. Epub 2018 Jan 12.
    Department of General Practice, Groningen Research Institute for Asthma and COPD, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands; Unit of Pharmacoepidemiology and Pharmacoeconomics, Department of Pharmacy, University of Groningen, Groningen, The Netherlands.
    Nonadherence to treatment, and its associated health and economic burden, is particularly problematic in asthma and chronic obstructive pulmonary disease management because of heterogeneous patient populations and the need for an inhaled route of drug administration. Symptom variability, comorbidities, and device switching further add to suboptimal adherence rates. As opposed to controlled clinical trials, real-life studies show consistently low inhaler adherence in daily practice, yet exact adherence rates have long been affected by disagreement on standardized definitions.

    The Role of Tiotropium+Olodaterol Dual Bronchodilator Therapy in the Management of Chronic Obstructive Pulmonary Disease.
    Tuberc Respir Dis (Seoul) 2018 Jan;81(1):13-18
    Department of Respiratory Medicine, Royal Devon and Exeter Hospital, Exeter, UK.
    Bronchodilator therapy is central to the management of chronic obstructive pulmonary disease and are recommended as the preferred treatment by the Global Obstructive Lung Disease Initiative (GOLD). Long acting anti-muscarinics (LAMA) and long acting β₂ agonists (LABA) are both more effective than regular short-acting drugs but many patients remain symptomatic despite monotherapy with these drugs. Combination therapy with LAMA and LABA increases the therapeutic benefit while minimizing dose-dependent side effects of long-acting bronchodilator therapy. Read More

    Cigarette Smoke Increases Endothelial CXCL16-Leukocyte CXCR6 Adhesion In Vitro and In Vivo. Potential Consequences in Chronic Obstructive Pulmonary Disease.
    Front Immunol 2017 13;8:1766. Epub 2017 Dec 13.
    Department of Pharmacology, Faculty of Medicine, University of Valencia, Valencia, Spain.
    Cardiovascular disease (CVD) is a major comorbidity in chronic obstructive pulmonary disease (COPD). Although the mechanism of its development remains largely unknown, it appears to be associated with cigarette consumption and reduced lung function. Therefore, the aim of this study was to investigate the potential link between water-soluble cigarette smoke extract (CSE)-induced endothelial dysfunction and the function of CXCL16/CXCR6 axis on the initial attachment of leukocytes, in addition to its possible impact on COPD-associated systemic inflammation.

    We describe the first isolation of Mycobacterium hassiacum, a rapid-growing, partial acid-resistant mycobacterium, in a respiratory specimen from a patient with exacerbated chronic obstructive pulmonary disease. To provide therapeutic recommendation for future cases, antibiotic susceptibility testing of 3 clinical isolates was performed by broth microdilution. All strains tested showed susceptibility to clarithromycin, imipenem, ciprofloxacin, and doxycycline. Read More

    Clinical and inflammatory phenotyping by breathomics in chronic airway diseases irrespective of the diagnostic label.
    Eur Respir J 2018 Jan 11;51(1). Epub 2018 Jan 11.
    Dept of Respiratory Medicine, Academic Medical Centre, Amsterdam, The Netherlands.
    Asthma and chronic obstructive pulmonary disease (COPD) are complex and overlapping diseases that include inflammatory phenotypes. Novel anti-eosinophilic/anti-neutrophilic strategies demand rapid inflammatory phenotyping, which might be accessible from exhaled breath.Our objective was to capture clinical/inflammatory phenotypes in patients with chronic airway disease using an electronic nose (eNose) in a training and validation set.

    Program of Integrated Care for Patients with Chronic Obstructive Pulmonary Disease and Multiple Comorbidities (PIC COPD+): a randomised controlled trial.
    Eur Respir J 2018 Jan 11;51(1). Epub 2018 Jan 11.
    Medical Health Service, Michael Garron Hospital, Toronto, ON, Canada.
    We sought to evaluate the effectiveness of a multi-component, case manager-led exacerbation prevention/management model for reducing emergency department visits. Secondary outcomes included hospitalisation, mortality, health-related quality of life, chronic obstructive pulmonary disease (COPD) severity, COPD self-efficacy, anxiety and depression.Two-centre randomised controlled trial recruiting patients with ≥2 prognostically important COPD-associated comorbidities.

    Smoking duration alone provides stronger risk estimates of chronic obstructive pulmonary disease than pack-years.
    Thorax 2018 Jan 11. Epub 2018 Jan 11.
    Division of Pulmonary, Allergy and Critical Care Medicine, University of Alabama at Birmingham, Birmingham, Alabama, USA.
    Background: Cigarette smoking is the strongest risk factor for COPD. Smoking burden is frequently measured in pack-years, but the relative contribution of cigarettes smoked per day versus duration towards the development of structural lung disease, airflow obstruction and functional outcomes is not known.

    Methods: We analysed cross-sectional data from a large multicentre cohort (COPDGene) of current and former smokers. Read More
