    • "The participants included five women and three men, with ages ranging from 58 to 84 years, with a mean age of 68 years. This age range is representative of the wider population of COPD patients (Devereux, 2006). Five patients lived with their spouse and three patients lived alone. "

    ABSTRACT: Home telehealth can provide considerable benefits to people diagnosed with chronic obstructive pulmonary disease, yet 20% of patients abandon telehealth. Identifying the factors that affect whether or not a patient decides to continue using telehealth is therefore crucial to the goal of mainstreaming telehealth. However, studies to date have only assessed the perceptions of patients who are not currently using telehealth, have used telehealth in experimental sessions, or are enrolled in a trial. The aim of the present study was to explore the beliefs and perceptions of patients with chronic obstructive pulmonary disease currently using home telehealth and who are not enrolled in a trial. Semistructured interviews were conducted with 8 patients with chronic obstructive pulmonary disease. Interviews were analyzed using interpretative phenomenological analysis. Four superordinate themes are presented: (a) perceiving benefits of "being watched over" as providing peace of mind, (b) learning about the health condition and the impacts on self-management behavior, (c) active engagement in health service provision and better access to health care, and (d) valuing the importance of in-person care. Users generally describe home telehealth in positive terms; however, patients still value face-to-face contact with health care professionals. The positive aspects of home telehealth, such as better access to health care and providing peace of mind, could be communicated to prospective users to improve uptake. Similarly, sustained use of telehealth is likely to be ensured if occasional visits from health care professionals are maintained. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

    • "It is currently the 4th most common cause of death in the USA and Europe, after cardiovascular diseases, cancer, and road traffic injuries. In light of the increasing number of smokers in the developing countries, particularly in China, COPD is prognosticated to become the 3rd most common cause of death globally by the year 2020 [1]. The main characteristic of COPD is a progressive, irreversible narrowing (obturation) of the bronchi that obstructs the air passage through the bronchi to the lungs. "

    ABSTRACT: The effect of smoking cessation on the oxidative stress in patients with chronic obstructive pulmonary disease (COPD) was assessed. We recruited 73 smokers with COPD (study group), whose blood was analysed before smoking cessation, after the 1st, 2nd, and 3rd months of abstinence, 35 healthy nonsmokers (Control I), and 35 smokers with COPD (Control II). Blood was taken once in Control I and 4 times (every month) in Control II. In the study group conjugated dienes (CDs) level in plasma and erythrocytes before smoking cessation was 3 and 6.5 times higher than in Control I, respectively (P < 0.001), while thiobarbituric acid-reactive substances (TBARS) level was 89% (P < 0.001) and 51% higher (P < 0.01), respectively. Superoxide dismutase (SOD) activity was 40% higher (P < 0.05) while glutathione peroxidase (GPx) was 41% lower (P < 0.001) than in Control I. In Control II, the similar differences as compared to Control I were observed throughout the study. Smoking cessation resulted in decrease of CDs, TBARS, and SOD and GPx increase, with no changes in catalase and vitamins A and E. COPD is accompanied by oxidative stress. A three-month tobacco abstinence facilitated restoring the oxidant-antioxidant balance systemically, but it did not affect spirometric parameters.

    • "Pulmonary function abnormalities in COPD include reduction in maximal forced expiratory flow, increased airway resistance and decrease in inspiratory capacity.[13] Forced expiratory volume in 1 s is used to classify the severity of COPD, and acts as a predictor of mortality.[16] "

    ABSTRACT: Evidence supports the use of pulmonary rehabilitation in the treatment of chronic obstructive pulmonary disease (COPD) patients both during acute exacerbation and at later stages. It is used in India; but, to date, there has been no study that has investigated the structure of pulmonary rehabilitation programs for COPD patients in India. The recent study aims to determine the current practice patterns of Indian Physiotherapists for COPD patients admitted in Intensive Care Units (ICUs) and wards in terms of assessment and treatment. A questionnaire-based survey was conducted across India. Questionnaires were distributed to around 800 physiotherapists via E-mail. Physiotherapists with a Master Degree and a specialization in cardiopulmonary science or a minimum of 1 year of experience in treating cardiopulmonary patients were included. The questionnaires addressed assessment measures and treatment techniques given to COPD patients. A total of 342 completed questionnaires were received, yielding a response rate of 43.8%, with a majority of responses from Karnataka, Maharashtra and Gujarat. The assessment and treatment techniques used were almost similar between ICUs and wards. More than 80% of the responders carried out the assessment of certain respiratory impairments in both ICUs and wards. An objective measure of dyspnea was taken by less than 40% of the responders, with little attention given to functional exercise capacity and health-related quality of life. Eighty-five percent of the responders used Dyspnea-relieving strategies and traditional airway clearance techniques in both ICUs and wards. Eighty-three percent of the responders were giving patients in the wards training for upper and lower extremity. Fifty percent were giving strength training in the wards. Whether patients are admitted in ICUs or Wards, the practice pattern adopted by Physiotherapists to treat them vary very little with respect to certain measures taken. Assessment predominantly focused on respiratory impairment measures, followed by dyspnea-quantifying measures, with little attention given to functional exercise capacity and health-related quality of life measures. Treatment techniques given were concentrated on dyspnea-relieving strategies, airway clearance techniques and upper and lower extremity exercises, with little attention given to strength training.
