NCT04383730
The authors hypothesized that inhaled sedation, either with isoflurane or sevoflurane, might be associated with improved clinical outcomes in patients with COVID-19-related ARDS, compared to intravenous sedation. The authors therefore designed the "Inhaled Sedation for COVID-19-related ARDS" (ISCA) non-interventional, observational, multicenter study of data collected from the patients' medical records in order to: 1. assess the efficacy of inhaled sedation in improving a composite outcome of mortality and time off the ventilator at 28 days in patients with COVID-19-related ARDS, in comparison to a control group receiving intravenous sedation (primary objective), 2. investigate the effects of inhaled sedation, compared to intravenous sedation, on lung function as assessed by gas exchange and physiologic measures in patients with COVID-19-related ARDS (secondary objective), 3. report sedation practice patterns in critically ill patients during the COVID-19 pandemics (secondary objective).
NCT02430753
The purpose of this study is to evaluate the safety and efficacy of irreversible electroporation (IRE) for Lung Neoplasms accompanied by Respiratory Function Insufficiency.
NCT05031858
Vojta therapy is a physiotherapy intervention with scientific evidence in respiratory pathologies in children and proven in adults. In this pilot study with an RCT design, its effect in adult patients with respiratory pathology caused by the SARS-CoV-2 virus will be studied. The non-invasive and non-painful technique consists of applying tolerable pressure to specific areas of the patient's body. The objective is to activate, in a reflex way, the ventilatory physiology. It is compared with the conventional respiratory physiotherapy approach.
NCT05032209
Most of clinical cohorts focused on the course of asthma over time and on the different phenotypes of asthma have investigated children and adults separately. The passage from childhood to adulthood is scarcely explored. In this context, we decided to explore the course of asthma severity from teenage to adulthood in children with severe asthma. The secondary objectives are to assess the quality of life and socioeconomic status in adulthood. This study will be both retrospective (data collected during childhood) and prospective (data collected during adulthood), multicentric and observational
NCT04261582
Aspirin Exacerbated Respiratory Disease (AERD) is a relatively homogeneous disease characterized by adult-onset severe asthma, development of non-cancerous growths in the nasal canal (i.e. nasal polyps) and aspirin allergy. The cause of AERD is unknown, although likely results from environmental insults in combination with genetic susceptibility. AERD disease homogeneity increases the possibility of discovering narrowly-defined genetic contributors, and makes it an ideal population to study the genetic and epigenetic changes that cause asthma. Researchers recently discovered that gene expression of epithelial growth and repair (EGR) genes are substantially decreased in bronchial airway epithelial cells of severe asthmatics compared to less severe asthmatics and healthy controls. This new finding indicates that epithelial integrity and related processes may be of primary importance to the development of severe asthma, and potentially the severe asthma subtype, AERD. This finding was later supported in a subsequent lab model, which showed that blocking a central epithelial repair and differentiation gene, human epidermal growth factor receptor 2 (ERBB2), decreased healing time of bronchial epithelial cells after injury. Thus, the objective of the proposed study is to determine whether EGR gene are also down-regulated in AERD, a homogeneous severe asthma subtype. As an extension, the researchers will also determine whether genetic mutations and/or epigenetic changes relate to and potentially explain this down-regulation of EGR genes. Specifically, the researchers plan to obtain gene expression of freshly brushed nasal airway epithelial cells of 140 AERD patients, 70 non-aspirin sensitive asthma patients, and 35 healthy controls, noting that nasal epithelial gene expression has recently been shown to mirror lung epithelial changes in asthmatic airways. Swabbing the nasal canal for epithelial cells allows to evaluate airway epithelial cell gene expression non-invasively. Our experimental design contrasts AERD gene expression profiles against healthy controls, and determines whether EGR genes are depressed in AERD relative to health controls. As a corollary, the researchers look to discover an AERD-specific gene expression profile which may one-day aid in diagnosis and expand current knowledge of disease mechanisms. As an extension, the researchers will correlate gene expression changes, specifically any finding of down-regulated EGR genes, with methylation changes (i.e. epigenetic changes) and genetic mutations.
NCT03443427
The purpose of this study is to test two different vaccine schedules to be used for administering the investigational NTHi Mcat vaccine that will be targeting patients with chronic obstructive pulmonary disease (COPD) to prevent acute exacerbations. An acute exacerbation is when the breathlessness in COPD patients will get even worse than it normally already is, sometimes to the point where oxygen therapy is required. In previous studies, study participants have received two doses of the vaccine according to a 0, 2 month vaccination schedule, in addition to standard care. The current study will find out if a third dose of the study vaccine against NTHi/Mcat is safe and working well. The study will also investigate if the third dose of vaccine works best when given after 6 months or after 12 months.

The aim of this trial is to study the effect of prone position during NIV and HFNC on acute hypoxemic respiratory patients.
NCT05021068
In recent studies with musculoskeletal system disorders in chronic respiratory patients, it has been reported that postural control is affected in COPD patients. The aim of this study to investigate relationship between spinal structure and mobility an severity of dyspnea in patients with COPD.
NCT03039621
The international multicenter double-blind placebo-controlled randomized clinical study in parallel groups.The objective of this study is to obtain additional data on the efficacy and safety of Ergoferon in the treatment of acute respiratory viral infections (ARVI) in children aged from 6 months to 6 years old.
NCT02668250
With the increasing aging population demographics and life expectancies, the number of very elderly patients undergoing surgery is rising. Elderly patients constitute an increasingly large proportion of the high-risk surgical group. Cardiac complications and postoperative pulmonary complications are equally prevalent and contribute similarly to morbidity, mortality, and length of hospital stay. Specific optimization strategy of general anesthesia has been tested in high-risk patients undergoing major surgery to improve outcomes. Our hypothesis is that a combined optimization strategy of anesthesia concerning hemodynamic, ventilation, and depth of anesthesia may improve short- and long- term outcome in elderly undergoing high risk surgery.
NCT05021796
In the coronavirus 2019 pandemic, on-the-job training for asthma counseling becomes more difficult. Telecounseling as a training platform becomes a mainstream of training during the pandemic. This study is designed to fill the knowledge gap for telecounseling as a training platform for asthma counseling among nurses.
NCT00811278
Inhaled corticosteroids are widely used as the primary therapy for asthma, which affects approximately 20 million people in the United States. While many patients respond to corticosteroid therapy, as many as 25-30% of patients with severe asthma have asthma that is difficult to treat or steroid insensitive. Predictive biomarkers for the rapid identification of patients with asthma who will achieve adequate control of their symptoms with inhaled corticosteroids has the potential to significantly improve asthma management. This proposal is based on the hypothesis that alterations in gene expression in epithelial cells of the buccal mucosa can be used as a reliable biomarker to predict corticosteroid response in patients with asthma. The goals of this proposal will determine if gene expression in epithelial cells of the buccal mucosa from patients with asthma is in concordance with gene expression profiles that have been identified through more invasive sampling techniques of the airway epithelium of asthma patients. The Specific Aims of this proposal are to 1) investigate the level of variability in gene expression of a subset of inflammatory markers in buccal epithelium from adult patients with asthma. Aim 1 will be carried out by collecting buccal samples from three cohorts of subjects (18-55 years of age) from the Pulmonology and Allergy Clinics at Truman Medical Center during regularly scheduled outpatient visits as follows: 1) healthy control adult subjects (n=10), 2) patients with asthma treated only with a short-acting beta2-agonist (SABA, n=10), and 3) patients with asthma treated with low-dose ICS (n=10). Relative gene expression of inflammatory markers will be determined using quantitative RT (reverse transcription)-PCR and variability in gene expression will be determined within and between the three cohorts. Data from the pilot studies described in this proposal will aid in the determination of appropriate study population sizes for future investigations with the long-term objective to use changes in gene expression (in buccal epithelial cells) as a dynamic biomarker for determining corticosteroid response in patients with asthma.

In addition the study will evaluate a 2-dose regimen administered 2 months apart to 62 subjects.
NCT02294630
Respiratory distress syndrome (RDS), caused by surfactant deficiency, is the leading cause of mortality and morbidity in preterm infants. Intratracheal instillation, the only approved means of surfactant delivery, requires endotracheal intubation and mechanical ventilation with their attendant risks. Interventions that decrease need for intubation and mechanical ventilation like noninvasive ventilation (NIV) including nasal continuous positive airway pressure, high flow nasal cannula or nasal intermittent mandatory ventilation are increasingly being used for initial respiratory support in preterm neonates with RDS to improve outcomes. Aerosolized surfactant delivered during NIV is an innovative and promising concept for the treatment of RDS - retaining the advantages of early surfactant with alveolar recruitment while obviating the risks of intubation and mechanical ventilation. The investigators overall hypothesis is that treatment of RDS with aerosolized surfactant in preterm infants undergoing NIV is safe and feasible and will result in short-term improvement in oxygenation and ventilation. The objective of this proposal is to perform a single-center unblinded Phase II randomized clinical trial of aerosolized surfactant for the treatment of RDS in preterm neonates undergoing NIV.

NCT02864459
When attempting to wean a patient from the ventilator, even if he/she passes the spontaneous breathing test, 10-20% of the time extubation failure occurs and the patient is reintubated. When the patient is reintubated the mortality rate increases and the length of intensive care unit stay is also increased. It is vital to intensively assess the patient before extubation and correctly predict extubation success. Muscular ultrasound may be helpful in these situations.
NCT04480879
This study is intended to evaluate the systemic pharmacokinetic (PK) characteristics and the safety of AZD8154 following administration of the Monodose DPI formulation compared with the administration of the nebuliser suspension.
NCT04838847
The primary objective of this study is to evaluate the humoral immune response to CVnCoV in elderly adults aged ≥65 years and younger adults aged 18-45 years, 14 days after the second dose administration.
NCT03089970
Respiratory virus infections cause a majority of asthma exacerbations in the fall to spring months. Current diagnostic platforms for respiratory viruses have limitations including cost, availability, and invasiveness. The use of noninvasive breath collection to analyze breath metabolites may be used to differentiate virus-infected asthmatics from other causes of acute asthma exacerbations.

Asthma is the most common chronic condition among children, and the third leading reason for hospitalization of children in the United States. It exerts a large healthcare burden on the US with estimated annual direct healthcare cost of approximately $50.1 billion with indirect costs of $5.9 billion. Asthma is characterized by airway inflammation and airway constriction. Albuterol and other betaagonists are first line standard of care for acute exacerbations and provide short acting smooth muscle relaxation and subsequent airway opening. The frequency of albuterol administration is dependent on the severity of the exacerbation. For hospitalized patients here at Children's Memorial Hermann (CMHH), patients may receive nebulized albuterol continuously or if the exacerbation is not as severe, receive albuterol intermittently. Intermittent albuterol frequency ranges from every two hour treatments, every three hour (q3h) treatments, or every four hour (q4h) treatments. As patients recover from their acute exacerbation, their frequency of albuterol administration is progressively titrated along this continuum. Expert consensus uses q4h albuterol as discharge criteria from the hospital. However, recent QI initiatives have studied the effect of q3h treatments as the discharge cutoff with no reported changes in safety or harm. There are no randomized controlled trials available. Furthermore, there are no economic evaluations available to see if costs saved by decreasing the length of hospital care are merely being shifted to subsequent clinic or emergency room care costs. The investigators aim to conduct a randomized control trial to compare q3h vs. q4h albuterol as hospital discharge criteria for patients admitted for acute asthma exacerbations. The investigators also propose to conduct a costeffectiveness analysis of the trial. If the hypothesis that q3h albuterol is safe and as effective as q4h albuterol as discharge criteria, the investigators would be able to argue for a new standard of care that is more cost effective for this very costly and common disease of children in the United States
