Active clinical trials for "Lung Diseases"

The objective of this study is to administer and validate a disease specific health related quality of life (HRQOL) survey for patients with Chronic Hypersensitivity Pneumonitis (CHP).

The primary aim of this study was to compare patients-rated evaluation and caregiver's assessment of dyspnea with the standard tools in pulmonology unit (Borg scale and visual analog scale) and the secondary aim was to performed an analysis depending on the diseases (lung cancer vs. other lung diseases) and to verify the agreement between the evaluation between both visual analog scale and modified Borg scale.

This retrospective study characterizes the clinical course and identifies four independent predictors of Acute Respiratory Distress Syndrome (ARDS) after burn injury (post-burn ARDS; pbARDS). In addition, a clinically useful prognostic score for pbARDS is introduced (ARDS burn score), which was derived from these independent predictors. The newly developed score may be helpful for the development of specific treatment strategies.

Chronic Obstructive Pulmonary Disease (COPD) is the fourth most important cause of death worldwide and is one of the commonest non-communicable diseases (NCDs) in Nepal. The presence of risk factors like indoor and outdoor air pollution, the high prevalence of smoking and lack of general awareness of COPD makes it a serious public health concern. However, no attempt has been made in Nepal to estimate its burden and address the disease at the community level. This community-based cluster randomized controlled study aims to fulfil that gap through mobilization of Female Community Health Workers (FCHVs) who will be trained to perform a certain set of health promotion activities aimed at prevention of the disease and its progression. Baseline and follow-up surveys will be conducted to compare the intervention and control groups. This study has the potential to generate evidence in helping address NCDs in Nepal and also other similar resource-limited countries.

Background : Long-term home non-invasive ventilation (NIV) can be proposed as treatment for acute respiratory failure with severe alveolar hypoventilation. The aim of NIV is to correct both daytime and night-time hypoventilation and associated symptoms and to provide the patient with adequate night-time oxygen saturation. The benefits of long-term NIV in the management of chronic obstructive pulmonary disease (COPD) patients in a stable state remain controversial. This highlights the importance of identifying the predictive factors for good compliance to the NIV, defined as a use of more than 4 hours per day. Aim of the study: The main objective is this observational study is to monitor the home NIV compliance over a period of 1 year under real conditions of treatment in patients with COPD newly initiated onto NIV (with telemonitoring or not) in order to specify the predictive criteria for good compliance. The secondary objectives are to assess the evolution of functional respiratory data, NIV parameters and changes in prescription, occurrence of acute exacerbations of COPD, hospitalizations and death, patient outcomes (quality of life and acceptability of NIV). Study design: a cohort of 120 patients with COPD newly initiated onto home-NIV (with telemonitoring or not), either in a stable state or following an acute exacerbation will be enrolled in the study and follow-up over 1 year. Data will be collected by lung specialists and home health care provider teams at 1-month post-initiation of NIV, 6 months and 1 year. The study is conduct in France.

Background: In non-invasive cardiopulmonary exercise testing (CPET), oxygen pulse (O2P) is defined as oxygen uptake divided by heart rate and is equal to the product of stroke volume and oxygen extraction by cells. As per, the O2P indicates the capability of oxygen consumption of whole body tissues and cells per heart beat. During exercise, the O2P changes can be deemed as the stroke volume changes as the oxygen extraction by muscle cells are normal. Hence, CPET-O2P can be non-invasively and continuously used to monitor the stroke volume changes during exercise. O2P value (i.e., % of predicted) is related to the severity and prognosis of heart failure and to the severity of constraint of the heart caused by exercise-induced hyperinflation or air trapping in patients with chronic obstructive pulmonary disease (COPD). However, O2P plateau pattern is not uncommonly encountered in the daily practice. Hypothesis and aims: O2P patterns during incremental exercise are seldom investigated although they have been hypothesized that the plateau or decreasing patterns are related to myocardial failure or ischemia. In this proposal, the O2P patterns are to be thoroughly investigated: (1) the patterns in norms, patients with heart failure and COPD, (2) the relationship between the O2P pattern and cardiac function and/or myocardial ischemia in patients with heart failure and COPD. As yet there are no relative reports on the O2P pattern and its possible mechanisms in the literature, the results of the proposal might tremendously impact the interpretation strategy of CPET reports. Methods: Multidisciplinary, prospective, comparative cross-sectional study is designed. Subjects aged from 40-85 years with the BMI of 18-28kg/m2 are to be enrolled: sample sizes of the norms, heart failure and COPD groups are 10, 20, and 20, respectively, equally distributed in two years. The definitions of COPD and heart failure with NYHA class I-III are according to the GOLD and ESC guidelines, respectively。All the three groups undergo CPET-NIRS, echocardiography, and the first pass and myocardial perfusion studies using Tc-99. The primary measurements are the O2P patterns and the cardiac function measured with echocardiography, the first pass and myocardial perfusion studies and air trapping in the lungs.。 Statistical analysis: For normal continuous data, t-test or ANOVA is used. For non-normal data, the Mann-Whitney test is used. The chi-square test or Fisher's exact test is used to compare the proportion of categorical variables between the two groups. A p value of less than .05 is considered to be statistically significant. Statistical procedures are performed using the SAS software package version 9.3.

Diffuse interstitial lung disease brings together a heterogeneous group of pulmonary pathologies, characterized by infiltrating and diffuse lesions of the pulmonary interstitium. The evolving risk of these ILD is pulmonary fibrosis, with the development of chronic respiratory failure. The process of the etiological diagnosis of ILD results from a multidisciplinary approach (pulmonologists, radiologists, occupational health specialists, anatomo-pathologists, etc…). Indeed, the multitude of possible causes of these diseases makes the etiological diagnosis difficult. Professional aetiologies are also frequently mentioned : pneumoconiosis, hypersensitivity pneumonitis, as a differential diagnosis. It therefore appears essential to deepen the professional aspect during the diagnostic process for ILD. Since May 2020, a professional interview has been systematically offered by the Occupational Pathology Consultation Center of the Hospital Center Lyon Sud, to patients followed by the team of Professor Vincent COTTIN, whose file was discussed in a multidisciplinary meeting. The data collected to constitute a database are the following variables: age, sex, diploma, professional course coded in CITP (International Standard Classification of Professions) and NAF (French Nomenclature of Activities), occupational exposures, smoking, risk factors non-professionals, clinical elements of ILD and elements relating to an occupational disease certificate. This database is anonymized.

Objective measurement of physical activity has several advantages compared to declarative measures: exemption from memory bias and desirability bias, more precise evaluation, taken into account activities of low intensity, measurement of physical activity and sedentariness profiles (number and duration of periods of activity, number of breaks in sedentary lifestyles). The aim of this study is to assess the early postoperative mobility of patients who have undergone pulmonary excision by thoracoscopy or robot surgery using ActiGraph GT3X accelerometer. This assessment will serve as a reference element for further studies.

A pharmaco-epidemiological, observational study that aimed at assessing in a prospective manner the evolution of Quality of Life (QOL) in chronic obstructive pulmonary disease (COPD) patients treated with inhaled bronchodilators

The purpose of this study was to investigate the prevalence of chronic bronchitis in patients suffering from moderate to very severe chronic obstructive pulmonary disease (COPD), and to assess the difference in exacerbation rates in patients suffering from moderate to very severe COPD with chronic bronchitis vs. a population of patients without chronic bronchitis.
