In this paper, we prove some strong and Δ−convergence theorems of total asymptotically nonexpansive non-self mappings in CAT (0) spaces. Our results extend and improve the corresponding recent results announced by many authors. Mathematics Subject Classifications: 47H09, 47J25

BACKGROUND The GOLD multidimensional classification of COPD severity combines the exacerbation risk with the symptom experience, for which 3 different questionnaires are permitted. This study investigated differences in physical activity (PA) in the different GOLD quadrants and patient's distribution in relation to the questionnaire used. METHODS 136 COPD patients (58±21% FEV1 predicted, 34F/...

BACKGROUND Patient centred outcomes, such as health status, are important in Chronic Obstructive Pulmonary Disease (COPD). Extensive questionnaires on health status have good measurement properties, but are not suitable for use in primary care. The newly developed, short Clinical COPD Questionnaire, CCQ, was therefore validated against the St George's Respiratory Questionnaire (SGRQ). METHODS...

Patients with chronic obstructive pulmonary disease (COPD) present with a variety of symptoms that significantly impair health-related quality of life. Despite this, COPD treatment and its management are mainly based on lung function assessments. There is increasing evidence that conventional lung function measures alone do not correlate well with COPD symptoms and their associated impact on pa...

BACKGROUND Spontaneous sputum production occurs in a subset of COPD patients; however, its clinical relevance has not been established. Differences in health status and clinical outcomes between patients with and without positive sputum cultures are unknown. OBJECTIVE To compare clinical characteristics and health status of spontaneous sputum producers with a positive culture (SC+) and negati...

BACKGROUND This study utilized a validated combination of a COPD Population Screener (COPD-PS) questionnaire and a handheld spirometric device as a screening tool for patients at high risk of COPD, such as smokers. The study aimed to investigate and pilot the feasibility and application of this combined assessment, which we termed the "VitalQPlus", as a screening tool for the early detection of...

BACKGROUND The new Global Obstructive Lung Disease (GOLD) guidelines advice to focus treatment in Chronic Obstructive Pulmonary Disease (COPD) on improvement of functional state, prevention of disease progression and minimization of symptoms. So far no validated questionnaires are available to measure symptom and functional state in daily clinical practice. The aim of this study was to develop ...

Anxiety and depression are common comorbidities in patients with chronic obstructive pulmonary disease (COPD) and affect patients’ health status [1, 2]. Health status in COPD patients is frequently assessed by the St George’s Respiratory Questionnaire (SGRQ), which is a validated disease-specific questionnaire widely used in clinical trials [3], but complex and time-consuming to complete and sc...
