Active clinical trials for "Respiratory Tract Diseases"

This study will observe the inhaler technique of people using 13 different inhaler types; record any technique errors being made against checklists developed for each inhaler device based on their manufacturer's guidelines, and reeducate any observed inhaler technique errors as required.

This study is being done because researchers want to learn more about genes that control the immune response in the participant's lungs and blood when the participant have lung disease leading to respiratory failure. Primary Objective To evaluate the feasibility of performing single cell gene expression analyses on tracheal aspirates from immunocompromised pediatric patients with immune compromising conditions, including HCT recipients. Secondary Objectives To assess whether cell composition and activation states in longitudinally obtained tracheal aspirate and blood samples are able to distinguish unique immunopathology for each of the early post-HCT lung diseases. To assess whether cell composition and activation states in longitudinally obtained tracheal aspirate and blood samples are different between two immunodeficient patient populations (alloHCT vs non alloHCT) with lung disease and respiratory failure. To test the hypothesis that allogeneic T cell responses are implicated in the pathogenesis of early post-HCT lung diseases. Exploratory Objectives To correlate immune cell signaling in the lower respiratory tract and blood of patients with early post-HCT lung diseases with the presence or absence of pathogenic microbes at each site. To explore HLA testing in Tracheal Aspirates in samples where enough cells are present.

A new Coronavirus (SARS-CoV-2) emerged in Wuhan Province, China in December 2019 and rapidly spread around the world. To date, the data in the literature regarding the clinical and epidemiological characteristics of severe forms of CoVid-19 in patients with chronic respiratory disease are not well known. The hypothesis is that patients with chronic respiratory disease (COPD, asthma, bronchial dilatations, pulmonary hypertension, cystic fibrosis, obesity-hypoventilation syndrome, obstructive sleep apnea syndrome) infected with SARS-Cov-2 will have increased dyspnea and hypoxemia leading to hospitalization for severe forms more frequently than the general population. However, they do not appear to be more at risk of developing a critical form. This study is carried out in order to propose to estimate the prevalence of critical forms of CoVid19 among patients with chronic respiratory diseases hospitalized for severe forms.

An observational study to evaluate the accuracy of a digital cough monitoring tool to reflect the incidence of COVID-19 and other respiratory infections at the community level in the city of Pamplona, Spain.

The primary objective of this study is to identify and describe patient behaviors and clinical outcomes among patients who have tested positive for mild to moderate COVID-19.

The aim of this study is the implementation of Forced Oscillations Technique (FOT) in newborns and small infants using a novel commercially available device. The objective is to assess the feasibility of the method, provide normative data for the first months of life and describe short- and long-term changes in neonatal respiratory disorders. The study population will consist of term and preterm newborns admitted to the Neonatal Intensive Care Unit (NICU) or the Well-Baby Nursery of the University Hospital of Patras, Greece. It is estimated that 200 full-term and 150 preterm newborns will be enrolled during a period of 36 months (March 2021 - September 2022). Measurements will be performed using the TremoFlo N-100 via a face mask, with the infant in the supine position during natural sleep. At least 3 technically acceptable measurements (duration 10s each) will be obtained, as follows: Healthy full-term neonates: postnatal days 1, 2, 3 and at discharge Preterm neonates: NICU admission, postnatal days 1, 2 and 3, and on the first day of each additional gestational week until discharge All participants will be also measured at the age of 3, 6 and 12 months.

This project will use data obtained from a proprietary vision-based patient monitoring and management system (OxeVision) for measuring heart rate and respiratory rate which is in clinical use at the Coventry and Warwickshire Partnership NHS Trust.

Background: Induced sputum (IS) is a noninvasive methodology for evaluating airway inflammation in a large number of pulmonary diseases, i.e, Asthma, Chronic obstructive pulmonary disease and Interstitial Lung Diseases. Several studies have defined normal values and cut-off points for this technique based on cellular components of IS, such as percentages of eosinophils, neutrophils, macrophages and CD4/CD8 ratio of T cell lymphocytes. However, normal values and cut-off points for lymphocyte percentages indicative of pathology have not yet been established or validated. This component of IS has considerable clinical value. Similar to other constituents of IS, it can provide biological insights into the pathogenesis of respiratory disorders and contribute to establishing the diagnosis and guiding treatment management of a variety of airway diseases. The purposes of this study are to define normal values and cut-off points of lymphocytes in IS among individuals with respiratory disorders and healthy volunteers, and to verify the current reference values of the percentage of eosinophils, neutrophils and CD4/CD8 ratio in IS. Methods: A Cross Sectional study which includes a database on up to 900 patients who participated in various studies conducted in the Pulmonary Laboratory of Tel Aviv Sourasky Medical Center between 2005 to 2012 will be established. The study population will include patients diagnosed as having various pulmonary diseases and a group of healthy volunteers who will serve as controls. The cut-off for normal values of lymphocyte, eosinophil and neutrophil percentages and CD4/CD8 ratio in IS will be defined by using ROC curves and evaluating sensitivity and specificity. The comparison of the different values to those in the literature will be done by using the Spearman rank correlation. The results of this study will provide supplementary information on lymphocyte counts in IS for identifying and treating various respiratory diseases.

Allergic rhinitis (AR) and asthma are considered as "one airway, one disease". Although there is increasing evidence for an association between allergy and depression, it remains unknown if the relationship between AR and asthma has extra influence on the psychological status of the patients. The aim of our study was to investigate the influence pattern of asthma on the psychological status in AR patients. The Symptom Checklist-90 (SCL-90) was employed to analyze the psychological status of 524 individuals with AR. Independent sample T-tests, one-way ANOVA and multivariate ANOVA were used for data analyses.

the study aimed to determine the distribution of respiratory infections in Tunisian population and evaluate the frequency of antibiotics prescribed according to current international recommendations.
