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

The study is designed to investigate normal polysomnographic respiratory values of Chinese healthy children and adolescents. By collecting the polysomnography (PSG) data and parameters of respiratory and sleep architecture，we hope to characterize normal polysomnography values in Chinese children and adolescents and to establish respiratory reference values for pediatric polysomnography which based on Chinese children's data.

Targeted next generation sequencing (NGS) provides a promising method for diagnostic purposes by enabling the simultaneous detection of multiple gene mutations. This study is to evaluate the feasibility and application value by using NGS into identifying genomic mutations in multiple or multifocal primary lung cancers in cell-tumor DNA (ctDNA) from surgical patients

Current guideline-based criteria defining COPD do not meet the challenges set by the complex pathophysiology of the disease. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of COPD.

This study is based on the change in weight of hospitalized patients knowing that the diagnosis of malnutrition based on the presence of at least one clinical or laboratory test which anthropometric measures (Evaluation of diagnostic protein energy malnutrition in hospitalized adults ANAES , Guidelines Department, September 2003; HAS Strategy supported in cases of wasting energy and protein in the elderly April 2007). The goal of this study is to find the correlation between hospitalization and weight loss, significant risk factors for malnutrition in a situation of community-acquired pneumonia infection.

The incidence of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary embolism ist not clear. It is estimated to be up to 3.8%. Prospective data registration does not exist. Treatment of choice is pulmonary endarterectomy if the thromboembolic lesions are surgically accessible. Otherwise interventional therapy by means of pulmonary balloon-angioplasty (BPA) or medical therapy is indicated. In Germany, the majority of the patients is referred to three CTEPH centers: Kerckhoff Clinic, Saarland University Hospital and Hannover Medical School to evaluate the therapeutic options. Starting in January 2016 all incident patients will be de-identified and included prospectively. Risk factors, outcome and treatment will be documented.

The investigators have developed an early detection solution for lung and breast cancer. A system which can distinguish between different medical odors based on biosensors. Our product is user-friendly noninvasive, nonradioactive and nontoxic to the patients. The technology enables a high level of sensitivity and provides users with a quick lab response and a simple yes or no answer. The aim of this study is to contribute and detect the patient at the earliest possible stage, in a noninvasive, nonradioactive and nontoxic way. Exhaled breath and urine samples are a promising approach towards future possible lung and breast cancer screening method.

The investigators hypothesized that acute bronchitis will be associated with various bacteria and viruses.

This is a study to investigate the incidence of Obstructive Sleep Apnoea in Patient undergoing open heart Surgery . This will include enrolment of 400 patient undergoing open heart surgery .

To evaluate the correlation between clinical and ultrasound findings in children presented with signs suggestive of bronchiolitis and to validate an ultrasound score for bronchiolitis that will correlate with specific clinical outcomes.

With the perception that lung protective ventilation with regard to low tidal volume ventilation and limiting airway pressures improves outcome in ARDS (acute respiratory distress syndrome) and that the development of new technical devices of extracorporeal lung assist systems with lower complication rates support establishment of lung protective ventilation strategies these systems are more and more frequently used. All critically ill patients with and without ECLA (extracorporeal lung assist)/ECMO (extracorporeal membrane oxygenation) treatment are on high risk for muscle wasting, leading to more comorbidity and higher mortality risk. Besides inflammation malnutrition is known as one of the main risk factors. Over and underfeeding should be prevented. However nutritional aspects of patients on extracorporeal lung assist are hardly investigated. Up to now changes in metabolic rates induced by ECLA/ECMO are poorly described. Factors like work of breathing, changes in cardiac output and septic state are influencing energy metabolism but until now there is no tool for measuring energy expenditure in clinical routine for patients on ECLA/ECMO. Indirect calorimetry is a simple device only for patients without ECLA/ECMO system. Oxygenation and CO2 (carbon dioxide) elimination by the lung assist system can be calculated but is not implemented to clinical routine. The combination of indirect calorimetry and calculation of lung assist function at the same time would give us the chance to adapt nutrition rates to energy expenditure. This may prevent muscle wasting and weakness. This pilot study will include 40 participating patients during 8 month investigating nutritional therapy adapted to energy expenditure calculated by O2 and CO2 turnover rates in patients on ECLA or ECMO systems. The investigators aim is to describe a calculation to set nutrition targets in ECMO patients. Second the investigators will describe level of nutritional needs under consideration of different mechanical ventilation states. Third O2 consumption and CO2 elimination will be used to estimate cardiac output.
