Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Background: Dysphagia is frequently observed in subjects with chronic obstructive pulmonary disease (COPD). But tongue strength has not been investigated yet in COPD subjects. The investigators hypothesized that tongue strength is weaker in COPD subjects compared to normal subjects. Methods: This was a single-centre, observational, and cross-sectional study. Twenty-seven subjects with COPD and twenty-four age-matched control subjects were enrolled in this study. Isometric tongue strength was measured using a device fitted with a disposable oral balloon probe. The investigators also evaluated handgrip strength, gait speed, and appendicular skeletal muscle mass (ASM) to define participants as having sarcopenia. ASM, fat free mass index (FFMI), and skeletal muscle mass index (SMI) were measured by bioelectrical impedance analysis. Gait speed was measured using the 6-meter walking test. The eating assessment test-10 (EAT-10) was used to diagnose dysphagia.

The intention with the study is to have a better understanding of what happens to COPD patients' symptoms, lung function and markers of inflammation over 12 weeks. This information will increase the understanding of COPD and how to design new treatments for COPD in the future.

Chronic Obstructive Pulmonary Disease (COPD) is a widespread condition which causes a poorer health status, reduced exercise, and lung function impairment. COPD exacerbations are a sustained worsening of symptoms beyond day-to-day variation and are responsible for one in eight hospital emergency admissions. Although extensive users of healthcare, people with COPD are primarily responsible for their condition 99% of the time and self-management has been highlighted as a crucial component for COPD care. To enable greater awareness of changing symptoms, a self-management app (COPD Pal) will be created by Bond Digital Health Ltd (BDH) to enable people with COPD to input information pertinent to their condition. The aim of COPD Pal, which is akin to a paper diary, is to empower patients to take more control of their disease and allow them to provide healthcare professionals with accurate, personalised data during clinic consultations. This project aims to assess the usability and acceptability of COPD Pal using qualitative methodology (phase 1). It is proposed that 13-15 people with COPD will be invited to attend a focus group and be given COPD Pal (V1) with which to interact. Semi-structured questions will then be asked to facilitate conversation regarding their initial experiences of using COPD Pal. Focus groups will be audio-recorded, transcribed, and a Thematic Analysis conducted. Thematic themes will be provided to BDH, the creators of COPD Pal, with which to develop the app further (V2). Thematic themes will be provided to participants to confirm accuracy and ensure methodological rigour. A final report will be provided to both research participants and to BDH. Findings from this research will inform the second phase feasibility study of V2 of COPD Pal.

Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. Particularly, previous research of meridian phenomenon involved lots of subjective elements and outcomes.Researches that use modern scientific techniques to investigate the biological characteristics of meridians are urgently needed. Therefore, this study is designed to assess the metabolic characteristics of the Heart and Lung meridians by using functional near infrared spectroscopy. Thus, the biological characteristics of meridians could be presented objectively in a scientific methodology.

The primary objective of this study is to investigate the biological determinants of sputum rheology variations.

A retrospective analysis study in COPD patients for an exact follow-up period of 12 months (in subgroup analyses: 24 and 36 months); censoring of patients will only be done in case a patient died during the respective follow-up period.

The purpose of this study is determine the prevalence of undiagnosed Chronic Obstructive Pulmonary Disease (COPD) in population served and with exposure to cigarettes in the Region of Murcia

This is a cross-sectional validation study, designed to evaluate the discriminative validity of the Chronic Obstructive Pulmonary Disease Assessment Test translated in a local language in patients with Chronic Obstructive Pulmonary Disease.

Alpha-1 antitrypsin deficiency (AATD) is considered a rare genetic cause of chronic obstructive pulmonary disease (COPD) and liver disease. Recent data has suggested that AATD is not as rare as originally thought and undetected AATD may account for COPD in some patients. This study was designed to evaluate the frequency of undetected AATD in a population reporting to academic pulmonary function testing facilities who meet criteria for the diagnosis of COPD. All individuals meeting GOLD criteria for COPD will be consented and offered free testing for AATD. The results will help identify the percent of those with COPD who have undetected AATD.

The purpose of this study is to determine the prevalence of pulmonary embolism in our population of Chronic Obstructive Pulmonary Disease (COPD) patients admitted to hospital with dyspnea. The patients will undergo investigation for pulmonary embolism, according to current guidelines.
