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

The purpose of this study is two-fold. In the first phase, the goal is to characterize the stability of respiratory (nasal swab, nasopharyngeal swab, and throat swab; NS, NPS, TS) and stool (raw stool and rectal swab) specimens collected using various standard, medically established procedures with and without transport media and tested at various time points and under different temperature conditions, and also to look at variation between repeat sampling events. The intention is for these data to support decisions made by BioFire regarding the appropriate specimen type and handling guidelines for future tests. In the second phase of the study, collection and transport conditions identified in Phase 1 will be used to collect specimens for pilot performance evaluations of a new molecular diagnostic test.

Hypothesis: Innate immunity is altered in certain patients with COPD and frequent exacerbations, a fact that makes them more susceptible to being infected by bacteria. The electronic nose is able to detect patterns of specific VOCs for exacerbations of infectious origin.

In 2009, centres that carried out lung resection for cancer were required to obtain authorization following the first cancer plan. One of the criteria to obtain authorization was the volume of activity: the centre had to carry out at least 30 lung resections per year for cancer. Five years later, it would be useful to know the impact of this new organization of oncology on the quality of care. To answer this question, the PMSI database is an ideal source of an indicator of quality: in-hospital mortality. This observational cohort study will be conducted using the national PMSI database with data covering the period from 1st January 2005 to 31st December 2013. It will be limited to hospitalization for lung resection. The time will be divided into 3 periods: 2005-2007, 2008-2010 and 2011-2013; the period 2008-2010 includes the implementation of authorizations for cancer surgery.

Severe asthma is a heterogeneous disease characterized by the need for treatment with high doses of inhaled corticosteroids. It affects 5%-10% of asthmatic patients, although it accounts for a significant percentage of the consumption of health care resources. Severe asthma comprises various clinical and pathophysiological phenotypes. In this current study, we aimed to clinical characteristics and cytokes profile in severe asthma patients.

Classically lung elastance and transpulmonary pressure are measured from the difference in tidal variations of airway pressure subtracted by tidal variations i esophagus pressure divided by the tidal volume. This requires the presence of a esophageal balloon catheter which is cumbersome and costly. In this study values obtained as described above are compared to values obtained with a new method in which a stepwise increase in positive endexpiratory pressure (PEEP) is performed with a size of the lung volume increase which corresponds to the tidal volume which the patient is ventilated with. The measurements are performed in sedated and mechanically ventilated patients in the intensive care unit.

Klebsiella pneumoniae is one of the most common pathogens causing both community-onset and nosocomial infection. More worse, the emergency of Carbapenem-Resistant Klebsiella pneumoniae (CRKP) had cause the clinical therapy be very difficult. However, there is not much empirical data as to the prevalence, risk factors, characteristics,outcomes and the rationality of the current therapy for the Klebsiella pneumoniae infection in China.Thus, the study was aimed to investigate the epidemiology and risk factors, characteristics, outcomes and the rationality of the current therapy for the Klebsiella pneumoniae infection in China.

Study the prevalence of the urinary incontinence among adults with respiratory diseases.

We have demonstrated for the very first time that it is possible to isolate CPCs (circulating pulmonary cells) in patients with COPD in a sample of 17 patients (with a recovery rate of nearly 40%) and none of 10 healthy, non- smokers controls with a patented method [provisional Spanish Patent Application (P201730724)], based on liquid biopsy methodology (Romero Palacios et at, submitted 2017), showing that patients with COPD and isolation of CPCs have a more severe disease (expressed as higher BODEx index) and a trend towards a higher rate of decline of lung function as well as an increased rate of exacerbations, suggesting that CPCs isolation could be of value as a diagnostic and prognostic tool identifying patients with more active diseases. However, due to the small sample, no definitive conclusions could be made. Moreover, as there were no healthy smokers included in this study, we couldn´t evaluate if CPCs could be isolated in this type of population. The fact that CPCs could be isolated in a group of patients with COPD and its relationship with greater severity suggests that this could be a marker of progression of the disease and could detect those patients more likely to benefit from newer antiinflamatory therapies(17)

This is a prospective observatory clinical study, aiming to establish and validate venous thromboembolism risk model in Chinese advanced non-small cell lung cancer.

Conduct a prospective study to confirm the value of circulating tumor DNA and its aberrant methylation in longitudinal monitoring of surgical lung cancer patients.
