Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

For patients with suspected pneumonia presenting to the emergency room, the imaging strategy most often involves a frontal and lateral chest x-ray despite poor diagnostic input. Indeed, the radiography is not very sensitive and specific for the diagnosis of pneumopathy compared to the scanner. However, the scanner remains the gold standard, the major constraint of which concerns the irradiation to which the patient is exposed. The new scanners allow ultra-low-dose scans with better sensitivity than standard radiography with an equivalent dose of radiation. In addition, the ultra-low-dose scanner helps prevent diagnostic errors and unintended treatments. A low-dose CT scan for suspected pneumonia has been possible in the Strasbourg emergency department since March 2019. The investigators therefore hypothesize that a diagnostic strategy involving the performance of a low dose CT scan in the event of suspicion of pneumopathy in the emergency room makes it possible to improve the adequacy of the diagnosis made by the initial imaging examination and the diagnosis on discharge from hospitalization, to reduce respiratory or hemodynamic complications and to reduce the prescription of antibiotic therapy that is not suitable for the patient. course of the imaging result validated by a panel of emergency physicians and infectious disease specialists based on medical records in accordance with the recommendations.

The purpose of this study is to learn more about breathing disorders during sleep. The investigators want to learn how breathing sounds made during sleep relate to breathing disorders during sleep.

The specific aim of this study is to gather data on fluid balance, intravenous medication administration, electrolyte balance, and diuretic and dialysis use in patients with acute respiratory failure who might benefit from a strategy designed to limit fluid administration.

The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.

The goal of this project is to find a series novel biomarkers by differential proteomic techniques that can improve the early diagnosis and develop a more efficient therapy to enhance ARDS patient survival rate.

The aim of this study is described as follows, To establish a validated method to test cough reflex sensitivity conducted by transient receptor potential vanilloid 1(TRPV1). To observe the variance of cough reflex sensitivity conducted by transient receptor potential ankyrin 1(TRPA1) of chronic patients and the relationship between cough reflex sensitivity conducted by TRPA1 and conducted by TRPV1. To study the distribution of TRPA1 and TRPV1 channels and their relationship to cough reflex sensitivity.

Description of the presence of cell-free fetal DNA in maternal plasma allowed the possibility of non-invasive prenatal diagnosis. Whereas detection of paternally-inherited alleles is straightforward and being quickly implemented in routine, detection of maternally-inherited alleles remains challenging. To date, the main approach that is being developped, called Relative Haplotype Dosage Analysis, relies on the identification of an allelic imbalance between the mother's wild-type and mutant alleles, relative to the fetal's contribution. This approach therefore requires the study of a propositus to identify the morbid haplotype, which is not always possible in the context of an ongoing pregnancy. In this study, we aim to evaluate the contribution of new technologies, such as linked-read Sequencing, to allow direct identification of parental haplotype in the context of non-invasive prenatal diagnosis.

Most existing medical research has focused on patients with well-established COPD and poor lung function. Whilst this is important because such patients have lots of symptoms and problems, in some respects a better way of reducing health problems in the future would be to develop a strategy which focuses on patients with milder disease, and identifies which ones will go on to develop more severe problems and why these problems occur. The research in this application is designed to investigate these issues. The main objective of the Partnership is to study the very early stages of the development of COPD. The investigators will do this by recruiting a novel cohort of smokers (age 30-45), in whom the investigators will follow the trajectories of lung function decline to identify prospectively those at risk of excess decline. This programme forms a unique UK consortium of 8 academic centres with excellent high quality publication records and broad experience in mechanistic, translational, clinical and epidemiological studies in COPD with key capabilities including primary care.

The purpose of this study is to determine the impact that treatment with a cellular concentrate derived from an individual's own fat, known as the stromal vascular fraction (SVF), has on the quality of life of people with chronic obstructive pulmonary disease (COPD). SVF contains multiple cellular components, including stem cells, with both regenerative and anti-inflammatory properties. This therapy has shown promise for ameliorating the symptoms of COPD. This study is designed to evaluate quality of life changes in individuals with COPD for up to 12 months following SVF treatment.

Long-term objectives of the basic research part are improvement of CAP-management with respect to therapy, diagnosis and prevention to contribute to a better care of patients with pneumonia.
