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

Left heart disease is the main cause of pulmonary hypertension. With the advent of the aging society, chronic heart failure has become a global public health problem. Therefore the prevalence of pulmonary hypertension due to the left heart disease is increasing. However, there is no research on the prevalence of pulmonary hypertension due to the left heart disease in China. Therefore, the aim of the present study was to describe real-world outcome of Chinese patients with pulmonary hypertension due to the left heart disease and identify factors that may predict outcome. Our study will profile the demographics, clinical course, treatments, and outcomes of pulmonary hypertension due to the left heart disease in China.

The purpose of this study is to observe the clinical manifestation, Lab findings including chest CT scans, pathological findings and outcomes in chinese patients with pulminary vasculitis.

This is a prospective specimen collection study targeting patients presenting with Influenza Like Illness (ILI) and/or Acute Respiratory Infection (ARI) in an out-patient setting. A non-invasive, user friendly sampling technique, using midturbinate flocked swabs will be used. These nasal swabs will be collected in different volumes of viral transport media (0.5mL and 3.0mL), for different dilution range of the viruses present in the collected biological specimen. The collection of nasal swabs samples will support the optimization of point of care detection methods for respiratory viruses responsible for ILI and/or ARI.

Subjects referred to a sleep clinic had polysomnography (PSG), clinic BP measurements, 24-hour ABP monitoring and HBP monitoring using a device (Microlife WatchBP HomeN) that allows daytime (3 days, 2 duplicate readings/day) and automated nighttime BP measurement (3 nights, 3 readings/night).

There is increased frequency of asthma in obese patients. This study is trying to find out if there is a difference in the presence of bronchospasm during anesthesia in obese and non obese patients.

to determine the values of imaging and genetic biomarkers for prediction of tumor aggressiveness and prognosis in patient with early stage lung adenocarcinoma to Identify unique copy number alteration in patient with early stage lung adenocarcinoma to evaluate the long-term change of ground-glass nodule combined with lung adenocarcinoma to suggest a guideline for planning an appropriate follow-up examination and management

The purpose of this study is to find out if we can predict the progress of acute upper respiratory tract infection to acute bacterial rhinosinusitis in Finnish conscripts by symptoms, clinical, endoscopic or radiological findings, middle meatal swab samples or nitric oxide measurement.

The purpose of this study was to determine occurrence of ventilator associated pneumonia (VAP) in tracheostomized patients with COPD discharged in invasive mechanical ventilation (IMV) compared to patients with CPOPD discharged with tracheostomy but in non invasive mechanical ventilation (NIMV).

The purpose of this study is to determine whether mucin is increased during pulmonay exacerbations in adult patients with cystic fibrosis (CF).

Late onset Hypothyroidism was found in infant with congenital hypothyroidism. The hypothesis is that infants with congenital hypothyroidism may lose thyroxin and other hormones via the chylothorax fluid causing transient hypothyroidism. In this study hormonal concentration will be measured in the chyle as well as hormonal serum level.
