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

Pleural effusion is an accumulation of fluid between the tissue layers that line the lungs and chest cavity. It has an estimated prevalence of 320 per 100,000 people in industrialized countries. The cause of the pleural effusion remains unclear in a substantial percentage of patients with persistently exudative effusions.

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.

Retrospective multicentric observational study exploring the population of adult neuromuscular patients presenting a respiratory distress requiring their admission in an Intensive Care Unit (ICU) for ventilatory support. Research of markers associated with long term mortality and ventilatory status.

This is a multicenter prospective collection of leftover respiratory tract secretions, paired blood and NP swabs, and clinical circumstances from pediatric HCT patients, followed by next generation genomic sequencing, transcriptome analysis, protein biomarker measurement, and statistical modeling.

Lung cancer is the leading cause of cancer-related death in China. This study will explore the applications of multiplex analysis of circulating tumor DNA biomarkers for diagnosis and surveillance of lung cancer patients

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 study aimed to evaluate the correlation between the point of care blood analysis obtained from skin puncture blood and conventional blood analysis obtained from venous and arterial blood.

This is an observational retrospective study. The primary objective is to investigate the expression and potential prognostic role of Programmed Death Ligand 1 (PD-L1) in tumor samples from 350 patients with early stage treatment-naive non-small-cell lung cancer (NSCLC). Tissue samples were embedded in a tissue microarray. PD-L1 will be studied by immunohistochemistry using the SP263 antibody. Stained samples will be evaluated independently by two operators. A tumor will be defined as positive when = or >50% of tumor cells express the ligand. The investigators will investigate the relationship between PD-L1 protein expression and overall survival and other clinical characteristics with appropriate statistical methods.

Community-Acquired Pneumonia has become common. Additionally, the mortality is high. But the epidemiology of pathogen is various in different areas, which is crucial for the key treatment. In addition, the risk factors of patients who died in 3 or 7 days in china is not clear, comparing with patients who died in 14 or 28 days or who survived.

Anxiety and depression are common comorbidities of chronic obstructive pulmonary disease (COPD). However, the exact prevalence is not known in China. COPD patients with anxiety and depression tend to have more severe symptoms and worse prognosis, but the related evidences are not strong enough. The study aim to investigate the prevalence and long-term outcome of anxiety and depression in COPD.
