Active clinical trials for "Lung Diseases"

The aim of the study is to investigate by flow cytometry the phenotype of alveolar macrophages (AMs) isolated from patients with non-infectious lung diseases.

This is a cross-sectional observational study, aiming to validate the accuracy of tidal breathing measurements in infants made by VoluSense Pediatrics, a lung function method based on electromagnetic inductance plethysmography, compared to an ultrasonic flowmeter. VoluSense Pediatrics consists of a flexible vest placed around the torso of the baby, and changes in tidal volume and flow is measured. The study will enable a better understanding of the usefulness of this equipment. The equipment is made by VoluSense Norway AS, and is owned by Haukeland University Hospital.

Current diagnostic tools used in pulmonary disease often do not meet the challenges set by the respective pathophysiology. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various pulmonary diseases.

The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.

The purpose of this study attempts to investigate the differences and relationships of respiratory parameters, muscle activity, and dyspnea during ADL between patients with COPD and age-matched healthy participants.

In this project, the clinical diagnosis of interstitial lung diseases was carried out for the population with suspected interstitial lung diseases selected from the community cohort, and the confirmed patients were included into the existing clinical cohort of interstitial lung diseases, forming an interstitial lung diseases special disease cohort consisting of 3,000 patients and corresponding matched control groups. According to characteristics of interstitial lung disease and the needs of National Key R&D Program of China, this study will formulate unified clinical follow-up strategy to do long-term standardized clinical follow-up in patients with interstitial lung disease. The detailed information for clinical diagnosis and treatment as well as biological samples were collected to identify disease phenotype and build the database and biological sample library for interstitial lung disease cohort study. This study aims to provide evidence for molecular classification, screening and validation of biomarkers as well as precise diagnosis and prevention in patients with interstitial lung disease.

Introduction. Nonspecific low back pain (NSLBP) is a very prevalent medical condition, especially in subjects with chronic obstructive pulmonary disease (COPD). The diaphragm is a respiratory muscle, but it takes part in trunk stabilization on lumbar spine. NSLBP is related to lack of spinal control. The COPD symptoms include lack of efficiency in diaphragm, which could be connected to NSLBP. Hypothesis and objectives. COPD can contribute to NSLBP. It is associated with diaphragm weakness, severity of respiratory function, lower level of physical activity and quality of life in COPD. Methods. A descriptive observational cross-sectional study was conducted with two groups: the first one with subjects with COPD and the second one with subjects without it. Data were collected on: pulmonary function; respiratory muscles strength; trunk postural control; quality of life with COPD; physical activity level; lumbar pain presence, intensity and disability. Data were collected in a single session.

This is an observational study in primary care aiming to validate biomarkers for chronic obstructive pulmonary disease (COPD).

To evaluate the health status of patients with Interstitial Lung Disease (ILD), and how this varies between subgroups of ILD. To investigate the prevalence of symptoms, anxiety, depression, and sleep-disordered breathing within ILD patient population. To assess the economic impact of ILD. To understand how self-aware ILD patients are regarding their treatment/management. To compare the demographic details, including smoking status and occupational history, of patients with interstitial lung disease

Skeletal muscle is composed of two fibre types which are intertwined. Skeletal muscle weakness, particularly of the walking muscles, is an important complication of Chronic Obstructive Pulmonary Disease (COPD) but so far the investigators do not know what mechanisms drive the process. All existing studies have investigated signalling pathways in the whole muscle so they have been forced to consider type I and type II fibres together. It is possible that disease selectively affects one fibre type, most likely type I fibres which are in fact lost in COPD patients. For this reason mechanisms of disease may have been overlooked by current studies. The applicants have acquired the technology which allows type I and type II fibres in a muscle specimen to be split (by laser capture microdissection) and so signalling pathways can be assessed separately in type II and type I fibres which is what this proposal sets out to do. The proposal therefore aims to capture well characterised clinical data from 60 COPD patients and 20 age matched controls, from whom a biopsy of the main walking muscle, the quadriceps, will be taken. In the samples the investigators will assess at a fibre specific level inflammatory signalling. Surplus material will be retained for subsequent fibre specific analysis.
