Study Objectives: Sleep quality is poor among patients with COPD, and studies show sleep disturbance is associated with low overall quality of life in this population. We evaluated the impact of patient-reported sleep quality and sleep apnea risk on disease-specific and overall quality of life within COPD patients enrolled in the SPIROMICS study, after accounting for demographics and COPD disease severity. Methods: Baseline data from 1,341 participants [892 mild/moderate COPD (FEV1≥50% predicted); 449 severe COPD (FEV1<50%)], were used to perform three nested (blocks) regression models to predict quality of life (Short Form-12 mental and physical components and St...

COPD patients have increased central arterial stiffness and muscle sympathetic nervous activity (MSNA), both of which contribute to cardiovascular (CV) dysfunction and increased CV risk. Previous work suggests that COPD patients have elevated carotid chemoreceptor (CC) activity/sensitivity, which may contribute to the elevated MSNA and arterial stiffness. Accordingly, the effect of CC inhibition on central arterial stiffness, MSNA and CV function at rest in COPD patients was examined in a randomized placebo-controlled study...

OBJECTIVE: Sedentary behaviour (SB) is harmful for health and well-being and may be associated with depression. However, little is known about the correlates of SB in people with depression. Thus, we investigated SB correlates among community-dwelling adults with depression in six low- and middle-income countries. METHODS: Cross-sectional data from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. The analysis was restricted to those with DSM-IV Depression or receiving depression treatment in the last 12 months...

Background: Nonadherence to medication and incorrect use of inhalers represent significant barriers to optimal disease management of patients with chronic obstructive pulmonary disease (COPD). Thus, health care professionals (HCPs) play a critical role in educating their patients on appropriate inhaler use and in ensuring medication adherence. However, many patients do not receive appropriate inhaler training or have not had their inhaler technique checked. Methods: The Real-life Experience and Accuracy of inhaLer use (REAL) survey was a computer-assisted, telephonic survey consisting of 23 questions gathering real-world information on correct inhaler use, inhalation technique, device attributes, adherence, dosing accuracy, training, correct device use, ease of use, and factors that influence patient adherence in commercially available inhalers delivering COPD maintenance therapy...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is associated with a non-shockable rhythm as presenting rhythm in out-of-hospital cardiac arrest (OHCA). Whether the severity of the underlying disease is related to presenting rhythm is unknown. We hypothesize that increased severity of COPD in OHCA patients is associated with an increased prevalence of non-shockable rhythm. METHODS: This study included OHCA patients ≥40 years from the Danish Cardiac Arrest Registry (2001-2014)...

Phosphodiesterase 4 (PDE4) inhibitors are a novel medication approved for airway inflammatory diseases including chronic obstructive pulmonary disease. Their role and application in asthma are controversial and not defined. A comprehensive search was performed in major databases (1946-2016) using the keywords: 'phosphodiesterase 4 inhibitor' or 'roflumilast' and 'asthma'. Placebo-controlled trials reporting lung function, airway hyperresponsiveness by direct challenge, asthma control and exacerbations, and adverse events were included...

BACKGROUND: The concept of clinical control in COPD has been developed to help in treatment decisions, but it requires validation in prospective studies. METHOD: This international, multicenter, prospective study aimed to validate the concept of control in COPD [control = stability (no exacerbations or impairment in CAT scores) + low impact (low level of symptoms)]. Data from the screening visit was used to: investigate the level of control, compare characteristics of patients according to the control status, and perform a sensitivity analysis of the levels of control using either clinical criteria or questionnaires (COPD Assessment Test -CAT- or Clinical COPD Questionnaire -CCQ-)...

BACKGROUND: Cardiovascular diseases play a major role in morbidity and mortality in the earlier stages of COPD. We hypothesized that systemic vascular dysfunction would be present even in patients who are currently considered at "low-risk" for negative cardiovascular outcomes, i.e., those with largely preserved FEV1 , few exacerbations and only mild burden of respiratory symptoms (GOLD spirometric grade 1, clinical group A). METHODS: 16 patients (FEV1  = 86 ± 13%) and 16 age- and gender-matched controls underwent measurements of: a) central arterial stiffness by pulse wave velocity, b) brachial flow-mediated dilation and c) forearm muscle oxygenation by near-infrared spectroscopy...

Lower respiratory tract infection (LRTI) is a broad terminology which includes acute bronchitis, pneumonia, acute exacerbations of chronic obstructive pulmonary disease/chronic bronchitis (AECB), and acute exacerbation of bronchiectasis. Acute LRTIs (ALRTIs) are one of the common clinical problems in community and hospital settings. Management of community-acquired pneumonia (CAP) and AECB may pose challenges because of diagnostic difficulty in differentiating infections caused by typical and atypical microorganisms and rising rates of antimicrobial resistance...

Background: Chronic obstructive pulmonary disease (COPD) is the fourth most common cause of death in the world, for which smoking is a common cause. It is preferable to diagnose COPD at an earlier stage and to assess its progression so that mortality and morbidity of the disease could be reduced. Hence, we conducted this study to assess parameters of body plethysmography in Indian population where the data are lacking and to assess whether the use of body plethysmography can detect COPD earlier...

BACKGROUND: Lung cancer is a leading cause of death and hospitalization for patients with chronic obstructive lung disease, (COPD); a detailed understanding of which clinical features of COPD increase risk is needed. METHODS: To identify clinical and imaging features of smokers, with and without COPD, that are associated with an increased risk of lung cancer, we performed a nested case-control study of COPDGene subjects with and without lung cancer, age 45-80, who smoked at least 10-pack years...

Background: The diagnosis of COPD is not always consistent with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy in daily clinical practice, especially in primary care. This study aimed to estimate the overall COPD prevalence and severity, to identify differences between newly and previously diagnosed patients, and to evaluate the potential COPD overtreatment in a smoking population attending a primary care spirometry surveillance program. Methods: A study was conducted in 10 primary health care centers of Central Greece during a 7-month period...

Purpose: We determined the extent and nature of stigma exhibited by a sample of Canadian cardiorespiratory physiotherapists toward people with lung disease who had a smoking history. Method: A quantitative online survey was distributed to Canadian cardiorespiratory physiotherapists, and an anti-smoking attitudes questionnaire was used to measure explicit stigma. We used two case studies with questions to measure implicit stigma. The first involved a patient with chronic obstructive pulmonary disease (COPD) and a smoking history, and the second described a patient with COPD with no smoking history...

BACKGROUND: In 2013, the Australasian Society of Lifestyle Medicine (ASLM) introduced shared medical appointments (SMAs) for managing chronic disease in clinical practice. The popularity of SMAs has increased with the shift towards a Health Care Homes model. Programmed shared medical appointments (PSMAs) are an extension of the standard SMA model, designed to help manage more complex and specific chronic disease issues. OBJECTIVE: The objective of this article is to describe the process of PSMAs and consider their use in primary care...

BACKGROUND: A significant proportion of patients with chronic obstructive pulmonary disease (COPD) remain undiagnosed. Characterizing these patients can increase our understanding of the 'hidden' burden of COPD and the effectiveness of case detection interventions. METHODS: We conducted a systematic review and meta-analysis to compare patient and disease factors between patients with undiagnosed persistent airflow limitation and those with diagnosed COPD. We searched MEDLINE and EMBASE for observational studies of adult patients meeting accepted spirometric definitions of COPD...
