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

Single-center retrospective study conducted on a population of patients with chronic hypercapnic respiratory failure treated by non-invasive ventilation at home, followed at the CHRU of Nancy. The objective is to assess the contribution of reading the NIV card with a standardized grid in their follow-up. The main objective is to assess the inter-observer agreement of a standardized NIV card reading grid, the secondary objective is to compare the results of NIV card reading between the usual NIV card reading method in the service and this same method completed by the addition of the standardized reading grid. The hypothesis is that the use of a standardized NIV card reading grid improves patient follow-up by standardizing their care.

Lung cancer is one of the leading cause of cancer related death in China. Lung cancer screening with low-dose computed tomography was considered as a better approach than radiography. However, the role of Lung cancer screening with Low-dose CT (LDCT) among Chinese people remains unclear. With rapid development of artificial intelligence (AI),the application of AI in detection and diagnosis of diseases has become research focus. Moreover, patients' psychological status also plays an important role in diagnosis and treatment. This study focuses on detection and natural history management of lung nodule and lung cancer with AI assisted chest CT among people living in North China, and aims to investigate epidemiological results, patients' medical records and social psychological status.

Pneumonia is a major cause of ICU admission, or may complicate ICU course. Among the causative pathogens, Stenotrophomonas Maltophilia is a rare pathogen, but affects usually patients with chronic pulmonary co-morbidities, or with long duration of mechanical ventilation and multiples treatment with broad spectrum antimicrobial therapy. However, there are only a paucity of data regarding epidemiology, impact and outcome of Pneumonia due to Stenotrophomonas Maltophilia in critically ill patients. Primary objective was to study factors associated with mortality in case of Pneumonia due to Stenotrophomonas Maltophilia. Secondary objectives were to describe factors associated with morbidity of Pneumonia due to Stenotrophomonas Maltophilia (duration of mechanical ventilation, ICU length of stay), and to report the characteristics of critically ill patients presenting Pneumonia due to Stenotrophomonas Maltophilia.

The aim of this study is to examine whether voice acoustic properties has an influence on sleep apnea. Sleep apnea syndrome is defined as a sudden stop of more than ten seconds multiple times during sleep. The syndrome is common especially among men and occurs in 2%-4% of the population aged 30-60. The syndrome diagnosis is performed by an ENT (Ear, Nose and Throat) physician. The diagnosis is based on evaluation of anatomical structures in the sound path (nose and throat, jaw, pharynx and oral cavity) and a Polysomnography (PSG) test which quantifies the number and duration of breathing pauses during night sleep and additional parameters that monitor sleep. The syndrome has many negative consequences for those who suffer from it, including fatigue , lack of concentration, hypertension, diabetes ,heart disease, stroke and even death. Therefore, early diagnosis is important.

A prospective study to evaluate consistency of different NGS-panel. Cell free DNA is purified from each malignant hydrothorax from NSCLC .Different NGS-panels are applied to perform in vitro diagnosis to detect Single Nucleotide Variants(SNV) and to calculate TMB value in these DNA samples.Consistency of enrolled NGS-panels are then evaluated by statistical analysis.

Chronic obstructive pulmonary disease is a common respiratory condition that is characterized by inflammation of the large and small peripheral airways , the alveoli and adjacent capillary networks. Severe airflow obstruction that imposes a significant load on the respiratory system is a major manifestation of Chronic obstructive pulmonary disease. The reduced expiratory airflow also causes air trapping at the end of expiration , producing alveolar pressure that are higher than atmospheric pressure before the next breath. This condition is intrinsic positive end-expiratory pressure .

•Sphenoid sinus is located in the body of sphenoid bone, closed with a thin plate of bone tissue that separates it from the surrounding important structures .Detailed, meticulous preoperative radiological study of sphenoid sinus is the key to successful and safe functional endoscopic sinus surgery and transsphenoidal surgery. The purpose of the study is to delineate the sphenoid sinus radiologically using the multislice computed tomography and to decrease morbidity and mortality during skull base surgeries as the sphenoid sinus is one of the most variable of all sinuses and its relation to vital vascular and nervous elements make its approach a challenge for endoscopic surgeons

The investigators intend to screen children who are suspected of having GAS tonsillitis. From each child we will take a throat culture and saliva sample to screen for molecular evidence of GAS.

This study forms an initial phase of work aimed at developing a learning health system (LHS), whereby data relating to asthma is extracted from patient electronic health records (EHRs) across Scotland, analysed to explore variations in clinical practice and then shared with general practices to highlight any improvements that can be made so that they can better support people with asthma. If successful, the investigators hope to progress to the main quality improvement phase involving an increased number of practices and then incrementally build this up to cover the whole of Scotland.

Early Aspiration Pneumonia is a frequent and dreadful complication in survivors of cardiac arrest. Therapeutic Hypothermia widely used in Intensive Care Unit for its benefice on post cardiac arrest syndrome may otherwise hide signs of early pneumonia that may occur without use of a reliable screening biological marker. The goal is to assess the diagnostic accuracy of bronchial alpha amylase measure to predict a risk of early aspiration pneumonia in patients successfully resuscitated after out-of-hospital cardiac arrest. In this prospective non interventional study we included patients resuscitated after cardiac arrest and treated with Targeted Temperature Management (TTM). A distal bronchoalveolar lavage using specific display (Combi-Cath) was executed immediately after admission for each patient with both biochemic and bacteriological analysis including dosage of bronchial salivary alpha amylase. Urea was used as a marker of dilution in the measure of bronchial and plasmatic alpha amylase. Aspiration pneumonia diagnosis was established with clinical and biological criteria. On this basis we intended to determine a threshold measure of alpha amylase predicting occurrence of aspiration pneumonia and allowing a guidance in antibiotherapy prescription. Sensibility and Specificity of this technique were determined.
