NCT01931579
Solitary pulmonary nodule has become a major challenge in respiratory clinical practice. According to published guidelines, their management often requires close CT follow up, PET CT and invasive procedures to obtain a definite histology. In this context, innovative endoscopic techniques refered as navigational bronchoscopy have proved to be efficient, for the localization and sampling of peripheral lung nodules. However, these techniques are unable to differentiate malignant lesions from benign ones, in-vivo, in real time. Confocal endo-microscopy (CELLVIZIO) of the distal lung - also refered as distal lung probe based confocal laser endo-microscopy or alveolar lung endo-microscopy - allows in-vivo imaging of the distal lung structures in real time. This prospective trial we will assess confocal endoscopy as a tool to localize the peripheral lung nodules and to differentiate benign from tumoral lesions. Objective(s) 1. To demonstrate that confocal endo-microscopy is not inferior to navigational endoscopy for the localisation of peripheral lung nodule 2. To demonstrate that confocal endoscopy can differentiate benign from malignant tumors Experimental design: Multicentric prospective controlled trial, conducted in three academic centers, specialized in interventional bronchoscopy, equipped with both navigational bronchoscopy and probe based confocal endo-microscopy. Subjects with peripheral lung nodule requiring navigational bronchoscopy will be explored using both Confocal endoscopy AND navigational bronchoscopy. Confocal probe will be inserted in the same catheter as used for the navigational bronchoscopy and confocal images will be recorded before sampling. An ancillary study using topical methylene blue as in situ will be conducted at the Rouen University Center. An ancillary protocol includes the use of in situ methylene blue deposition and 660 confocal endo-microscopy analysis.
NCT02649803
The purpose of this study is to learn the pediatric asthma control status under community management model. To learn the differences of pediatric asthma control status when subjects assigned to community hospitals or Shanghai Childrens Medical Centre. To learn the treatment adherence and the frequency of asthma attack under community management model.
NCT01748474
In a randomized, sham-controlled trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with pulmonary arterial or chronic thromboembolic pulmonary hypertension.
NCT01213706
In the present proposal the investigators wish to assess the effect of a single session with the device known as Exer-Rest® which applies Whole Body Periodic Acceleration (WBPA) on baseline airway blood flow (Qaw) and in Qaw variation, in current smokers, glucocorticoid-naïve asthmatics, and age-matched healthy never-smokers, with the expectation that the treatment will transiently increase the Qaw, and to a greater extent in the current smokers and patients with asthma who have endothelial dysfunction.
NCT02419391
A total of 63 subjects will be recruited into three groups (18 subjects per group will receive MVA BN RSV vaccine and three subjects per group will receive placebo). Liquid frozen suspension of MVA BN RSV. Each subject will receive two vaccinations with either MVA-BN RSV vaccine 1 x 108 TCID50 per 0.5 ml, 1 x 107 TCID50 per 0.5 ml or with placebo.
NCT00361972
This study will evaluate how heartburn may lead to different types of inflammation in one's airways. Additionally, the study will determine whether aggressive treatment of heartburn results in improvement in both symptoms of heartburn and asthma but also in documented improvement in airway inflammation as determined by biopsy. The results of this study will be important in directing future research into the relationship between heartburn and asthma and may provide a clue whether certain subtypes of asthma may be caused primarily by gastroesophageal reflux (GER).
NCT02854761
This study evaluates the safety and tolerability of the investigational drug EF-022 in the treatment of adult patients with Recurrent Respiratory Papillomatosis (RRP). Patients will be administered EF-022, either intramuscular or subcutaneous, for a period of 6 months. Preliminary effect of the drug on the disease will be evaluated by following the number and severity of the lesions in the respiratory tract and the effect on voice changes.
NCT00983658
This Phase II, double-blind, placebo-controlled, randomized, parallel-group study is designed to evaluate the efficacy, safety, and tolerability of huMAb OX40L administered to patients by IV infusion for the treatment of allergen-induced asthma.
NCT01479595
This study is designed to investigate the efficacy and safety of QBX258 in subjects with moderate to severe asthma.
NCT01763853
The need for fluid resuscitation (FR) in ICU patients with acute respiratory distress syndrome (ARDS) is common. Indeed, relative or absolute hypovolemia is a common phenomenon that the intensivist must recognize early and treat promptly. Fluid challenge may have adverse side effects associated with fluid administration. The diffusion within the interstitial space may favor edema formation and cause cardiac dysfunction by volume overload. Edema formation is global and may specifically alter pulmonary alveolar epithelial integrity, leading to enhanced alveolar edema and impaired gas exchange. Currently, two types of fluids are frequently used, crystalloids and colloids. Among colloids and compared to crystalloids, albumin has the theoretical advantage of causing greater volume expansion. We hypothesized that a fluid resuscitation therapy with albumin generates less pulmonary edema than a fluid resuscitation therapy with crystalloids. The aim of our study is to compare alveolar fluid clearance, as a marker of alveolar edema fluid resorption, in 2 groups of patients: those treated with albumin and those treated with crystalloid.

The purpose of this study is to determine the effect of nitric oxide for inhalation on the duration of mechanical ventilation in pediatric patients with AHRF.
NCT02466347
The objective of this pivotal study is to evaluate the relative bioavailability of Synflutide HFA 250/25 Inhaler and SeretideTM 250 EvohalerTM in healthy volunteers without charcoal block.

The purpose of the study was to describe early predictors and to develop a prediction tool that accurately identifies the need for mechanical ventilation in pneumonia patients with acute respiratory failure treated with High Flow nasal cannula.

NCT02825615
Purpose Two techniques of radial artery cannulation, ultrasound guided (USG) and conventional method (CM) were compared to find the better technique in general and in different hemodynamic subsets of patients. Method This is a prospective randomized, single center study of 100 patients. The details of the primary cannulation technique, number of attempts, time taken, failure and cross-over technique were recorded for three different hemodynamic subsets with Systolic blood pressure \<80 mm hg, 80-100 mm hg and \> 100 mm hg.
NCT02814994
The Acute Respiratory Distress Syndrome (ARDS) is one of common clinical critically diseases. In the United States, the incidence of ARDS reaches 31%, which is one of the main causes of death in patients. There is no unified treatment process for ARDS currently and the treatment measures are not yet standardized, so the standardization of ARDS treatment processes is needed to reduce mortality in patients. Following the evidence-based medicine principles and six-step treatment standards of ARDS, this study uses the method of multi-center randomized controlled clinical trials to evaluate the standardized treatment process of ARDS, which provides the basis for the standardized treatment of ARDS.
NCT01945944
Children who need to be on a ventilator often have thick secretions/mucus in their lungs. These secretions can obstruct the breathing tube and their windpipe, which can worsen lung function and prolong the need for the ventilator. Hypertonic saline is a medicine that is used to thin out secretions in patients with cystic fibrosis (and other conditions). We hypothesize that having children on a ventilator inhale this medication will shorten the amount of time that they need to be on the ventilator.
NCT01471431
The objective of this study is to determine whether use of the spontaneous breathing trial allows for earlier successful extubation of very low birth weight (VLBW) infants who are intubated for \>48 hours and have not yet been successfully extubated (extubated \>7 days).
