BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with cough, sputum production or dyspnoea and a reduction in lung function, quality of life and life expectancy. Apart from smoking cessation, there are no other treatments that slow lung function decline. Roflumilast and cilomilast are oral phosphodiesterase 4 (PDE4) inhibitors proposed to reduce the airway inflammation and bronchoconstriction seen in COPD. This is an update of a Cochrane review first published in 2011 and updated in 2013...

INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD), a progressive respiratory illness requiring long-term treatment, is a significant cause of morbidity, mortality and economic burden on the family as well as the country. In the tertiary health care facility where the study was carried out, it was observed that many COPD patients did not come for regular follow up. In these patients, treatment interruption may lead to increased morbidity and mortality. AIM: This study aimed to find out the reasons for defaulting follow up and treatment in COPD patients...

RATIONALE: Studies of excised lungs show that significant airway attrition in the 'quiet' zone occurs early in chronic obstructive pulmonary disease (COPD). OBJECTIVES: To determine if the total number of airways quantified in vivo using computed tomography (CT) reflects early airway-related disease changes and is associated with lung-function decline independent of emphysema in COPD. METHODS: Participants in the multi-centre, population-based, longitudinal CanCOLD study underwent inspiratory/expiratory CT at visit-1; spirometry was performed at four visits over 6-years...

BACKGROUND: Patients with mild or moderate chronic obstructive pulmonary disease (COPD) rarely receive medications, because they have few symptoms. We hypothesized that long-term use of tiotropium would improve lung function and ameliorate the decline in lung function in patients with mild or moderate COPD. METHODS: In a multicenter, randomized, double-blind, placebo-controlled trial that was conducted in China, we randomly assigned 841 patients with COPD of Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 1 (mild) or 2 (moderate) severity to receive a once-daily inhaled dose (18 μg) of tiotropium (419 patients) or matching placebo (422) for 2 years...

Since 1998, the Global Initiative for Obstructive Lung Disease (GOLD) has worked with health care professionals, medical researchers, and public health officials around the world to optimize the prevention, treatment, and management of COPD. GOLD has continually worked to ensure COPD management strategy recommendations are aligned with current published research. The 2017 GOLD report represents a major revision to GOLD strategy guidelines, the first such major revision in the last 5 years. As such, the 2017 report has significant implications for the diagnosis of COPD, the management of stable disease, and the treatment of exacerbations...

BACKGROUND: In multidimensional Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, the choice of the symptom assessment instrument (modified Medical Research Council dyspnea scale [mMRC] or COPD assessment test [CAT]) can lead to a different distribution of patients in each quadrant. Considering that physical activities of daily living (PADL) is an important functional outcome in COPD, the objective of this study was to determine which symptom assessment instrument is more strongly associated with and differentiates better the PADL of patients with COPD...

BACKGROUND: Lung diffusing capacity for carbon monoxide (DLCO) gives an overall assessment of functional lung surface area for gas exchange and can be assessed using various methods. DLCO is an important factor in exercise intolerance in patients with chronic obstructive pulmonary disease (COPD). We investigated if the intra-breath (IBDLCO) method may give a more sensitive measure of available gas exchange surface area than the more typical single breath (SBDLCO) method and if COPD subjects with the largest resting DLCO relative to pulmonary blood flow (Qc) would have a more preserved exercise capacity...

Renal function impairment in lung cancer patients with bone metastases was investigated, as this can limit the application of bisphosphonates representing the gold standard in the management of such cases. Clinicopathological data of 570 lung cancer patients were retrospectively analysed for changes in renal function parameters. Co-morbidities included hypertension (50%), COPD (33%) and diabetes mellitus (15%). Statistical analysis was performed with Fisher's exact tests and a Cox proportional hazards model...

BACKGROUND AND OBJECTIVE: Involvement of pulmonary vascular remodelling is a characteristic sign in COPD. Vascular mediators such as vascular endothelial growth factor (VEGF) and prostacyclin may regulate fibroblast activity. The objective was to study the synthesis of VEGF and interactions with prostacyclin and transforming growth factor (TGF)-β1 in lung fibroblasts from patients with COPD and healthy control subjects. To further explore the autocrine role of synthesized VEGF on fibroblast activity, studies were performed in human lung fibroblasts (HFL-1)...

BACKGROUND: Patients with upper third esophageal cancer or esophageal cancer with upper mediastinal paratracheal lymph node metastases are often precluded from surgery because of technical difficulties. With the aid of robotic surgery, an excellent overview and reach of the thoracic inlet can be accomplished. In this way, patients with upper mediastinal esophageal cancer are eligible for esophageal resection with curative intent. The aim of this study was to review the results of a consecutive series of patients who underwent robot-assisted minimally invasive esophagectomy (RAMIE) for tumors of the upper 1/3 of the esophagus or positive lymph nodes in the upper mediastinum...

INTRODUCTION: COPD is a major cause of mortality, and the unpredictable trajectory of the disease can bring challenges to end-of-life care. We aimed to investigate known prognostic variables and scores that predict prognosis in COPD in a systematic literature review, specifically including variables that contribute to risk assessment of patients for death within 12 months. METHODS: We conducted a systematic review on prognostic variables, multivariate score or models for COPD...

Lung imaging is increasingly being used to diagnose, quantify and phenotype chronic obstructive pulmonary disease (COPD). Although spirometry is the gold standard for the diagnosis of COPD and for severity staging, the role of computed tomography (CT) imaging has expanded in both clinical practice and research. COPD is a heterogeneous disease with considerable variability in clinical features, radiographic disease, progression and outcomes. Recent studies have examined the utility of CT imaging in enhancing diagnostic certainty, improving phenotyping, predicting disease progression and prognostication, patient selection for intervention, and also in furthering our understanding of the complex pathophysiology of this disease...

Current classifications of Chronic Obstructive Pulmonary Disease (COPD) severity are complex and do not grade levels of obstruction. Obstruction is a simpler construct and independent of ethnicity. We constructed an index of obstruction severity based on the FEV1/FVC ratio, with cut-points dividing the Burden of Obstructive Lung Disease (BOLD) study population into four similarly sized strata to those created by the GOLD criteria that uses FEV1. We measured the agreement between classifications and the validity of the FEV1-based classification in identifying the level of obstruction as defined by the new groupings...
