NCT03558737
Very low birth weight infants are at increased risk of requiring prolonged duration of mechanical ventilation and multiple intubations, both of which are risk factors for ventilator-induced lung injury and BPD. Thus, it is important to investigate respiratory support methods that are able to effectively oxygenate and ventilate these high risk preterm infants while reducing their risk of lung injury. Nasal high-frequency ventilation is one potential intervention that may decrease the risk of respiratory failure in very low birth weight infants. Small studies have shown effective respiratory support over short time periods in infants, however these studies use nasal high-frequency oscillatory ventilation. To the investigators' knowledge there is no published studies looking at the use of nasal high-frequency jet ventilation in this high risk population. Use of non-invasive high frequency ventilation (HFV) has been described as a rescue method following failure of other non-invasive ventilator modes or as a means to increase the success post-extubation. When used as invasive high frequency ventilation, high frequency oscillatory ventilation (HFOV) or high frequency jet ventilation (HFJV) utilize supraphysiologic respiratory rates and small tidal volumes which has been shown to inflict less lung injury than conventional modes of ventilation. Using a mechanical newborn lung model, nasal HFV has improved CO2 removal when compared to conventional NIPPV. Animal studies in the lab of Kurt Albertine have shown improved ventilation and oxygenation in the high frequency nasal ventilation group versus the mechanical ventilation group in a preterm lamb model leading towards better alveolar formation noted histologically. The investigators hypothesize that extubation of very preterm infants to nHFJV will significantly decrease the rates of reintubation compared to those infants extubated to NIPPV.

NCT05251467
Development of a new patient reported outcome measure (PROM) that will measure the daily burden of gastrointestinal symptoms over the previous 24 hour period for people with cystic fibrosis.
NCT06364527
The United Kingdom has a high prevalence of asthma (over 12%) and some of the worst health outcomes in Europe. The management of respiratory disease and associated patient outcomes has long been an area of focus and improvement for the National Health Service. With the advancement of digital health technology, there is the potential to transform patient care and improve outcomes. The Aptar Digital Health respiratory disease management platform, a digital therapeutic will be utilized to determine its value and how it supports: i) asthma patient engagement and facilitates communication between patients and providers to accelerate medication adherence; ii) asthma control through the use of the Asthma Control Questionnaire-5. In addition, spirometry and fractioned exhaled nitric oxide will be utilized during the study to validate and enhance current National Institute for Health and Care Excellence guidelines.
NCT01667146
Some people develop the condition called acute respiratory distress syndrome (ARDS). This is a condition where the lungs have become injured from one of a number of various causes, and do not work as they normally do to provide oxygen and remove carbon dioxide from the body. This can lead to a reduced amount of oxygen in the patient's bloodstream. Patients with ARDS are admitted to the intensive care unit (ICU) and need help with their breathing by being connected to a ventilator (breathing machine). ARDS can lead to injury in other organs of the body causing other problems but also death. Over the past few years, reducing the size of each breath delivered by the ventilator in conjunction with the use of an occasional sustained deep breath called a "recruitment manoeuvre" have been used to try to prevent further damage to the lungs in people with ARDS. This ventilator strategy (termed the PHARLAP strategy) has been shown in a small research study to have some beneficial effects without causing any obvious harm, when compared to a current best practice ventilator strategy. The main beneficial effects of the PHARLAP strategy were to increase the amount of oxygen in the blood and to reduce markers of inflammation (the body reacting to a disease process) in the body. This study was too small to make a strong conclusion, so this study will be much larger and will assess whether patients who have developed ARDS are better off when we use the PHARLAP strategy. Three hundred and forty patients will be enrolled into this study in multiple ICUs across Australia and New Zealand. The study hypothesis is that the PHARLAP strategy group will have a higher number of ventilator free days at day 28 than the control group.

A prospective basic science study for collection of training and testing data for development of Lifelight® Junior
NCT04099082
Bronchiolitis obliterans (BO) is the well-known manifestation of the chronic pulmonary graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The pathophysiology of BO is, however, poorly known. The available data strongly support the role of respiratory viruses, in particular paramyxoviruses (parainfluenzae virus (PIV), respiratory syncytial virus, metapneumovirus). It is likely that the alloimmune response triggered by the respiratory virus is inadequate and leads to the peribronchiolar fibrotic process. The objective is to analyze the kinetics of profiles of the blood and respiratory host responses resulting from a high or low parainfluenza respiratory infection, in order to evaluate if the occurrence of a BO is associated with a specific signature We will evaluate the predictive signature of a BO after a parainfluenza virus infection by characterizing the differences between the patients evolving and those not evolving to a BO at 2 months after the infection.
NCT06506123
This is a diagnostic study aiming to compare accuracy to detect and classify patient-ventilator dyssynchronies by a machine learning algorithm, compared to the gold-standard defined as dyssynchronies diagnosed and classified by mechanical ventilator and esophageal pressure waveforms analyzed by experts. The main question of this study is: • Are patient-ventilator dyssynchronies accurately detected and classified by an artificial intelligence algorithm when compared to experts analyzing esophageal pressure and mechanical ventilator waveforms?
NCT05881590
Pulmonary rehabilitation is an exercise and education programme that helps improve breathlessness and quality of life for people living with lung and breathing problems. It improves exercise levels and breathlessness and is a recommended treatment for people with lung diseases and symptoms. Standard pulmonary rehabilitation programmes involve individuals attending group classes at hospitals or community centres, twice a week for 8 weeks. These classes are supervised by physiotherapists. At the moment, there are long waiting times for pulmonary rehabilitation in the NHS. Some patients may prefer more pulmonary rehabilitation based in their own home. This might be because they find it difficult to travel to classes. Some would like to do more home pulmonary rehabilitation in between supervised classes or continue pulmonary rehabilitation after the 8-week supervised programme. The blending between supervised classes and home pulmonary rehabilitation is known as HYBRID PULMONARY REHABILITATION. Hybrid pulmonary rehabilitation is not being provided routinely in the NHS, but the NHS would like to see it used more as it might help reduce waiting times and give patients more choice on how to access pulmonary rehabilitation. The study will assess the feasibility of a larger study to provide strong evidence on patients' uptake and adherence to the hybrid programme, and the impact on patients' health outcomes and service delivery. The investigators will also look at what measures would be best to use in a larger study. The study will recruit up to 100 patients. These individuals will be aged 18 years or older, have respiratory disease and a referral for pulmonary rehabilitation. Individuals with reasons why they cannot exercise will be excluded. Participants will be provided with an application (App) that can be installed on a mobile phone. This App is called Active+me REMOTE and is made by a company called Aseptika Ltd (www.activ8rlives.com). Active+me REMOTE provides live online, video exercise classes; pre-recorded exercise classes; a walking programme; educational talks; and a care plan personalised for the user. Data will be collected at the beginning and end of the hybrid pulmonary rehabilitation programme and will include routinely collected data as part of usual care. Additional data will be collected via the App and trial surveys. The investigators will ask staff and patients about the experiences of the new way of delivering rehabilitation and explore how cost effective it is.
NCT06502405
The purpose of this study was to examine whether electrical impedance tomography (EIT) was capable of identifying the deteriorated lung function on a regional level during bronchial challenge testing and whether EIT may provide additional information during bronchial challenge testing and identify spatial and temporal heterogeneity of regional lung function.
NCT04425031
Patients with COVID-19 and hypoxaemic respiratory failure and admitted to the intensive care unit (ICU) are treated with supplementary oxygen as a standard. However, quality of quantity evidence regarding this practise is low. The aim of the HOT-COVID trial is to evaluate the benefits and harms of two targets of partial pressure of oxygen in arterial blood (PaO2) in guiding the oxygen therapy in acutely ill adult COVID-19 patients with hypoxaemic respiratory failure at ICU admission.
NCT04380701
Originally, the study was planned to include two parts, i.e., Part A and Part B, however Part B was cancelled due to changes in the overall clinical development plan. The objectives originally described for Part B have been implemented in the ongoing development via a pivotal Phase I/II/III trial BNT162-02/C4591001 (ClinicalTrials.gov NCT: 04368728). The conducted Part A was a dose-finding part to investigate the optimal dose of four different vaccines (BNT162a1, BNT162b1, BNT162b2, and BNT162c2), allowing dose adjustments upwards and downwards in younger participants. Doses tested in older participants and expansion cohorts were chosen based on acceptability of dosing in younger participants. The vaccines BNT162a1, BNT162b1, BNT162b2, and BNT162c2 were administered using a Prime/Boost (P/B) regimen with two doses given \~21 days apart. The vaccine BNT162c2 was also administered using a Single dose (SD) regimen. Four additional expansion cohorts (cohorts 11, 12, 13, and 14) aged from 18 to 85 years received BNT162b2 using a P/B regimen only. In cohort 11, participants received BNT162b2 using one 3 μg prime dose (Dose 1) and one 30 μg boost dose (Dose 2) of BNT162b2. Participants in cohorts 12, 13, and 14 received two doses of BNT162b2 30 µg, each.
NCT05900128
The aim of this study is to evaluate if physical activity could improve asthma control and management in adults. With this purpose we enroll asthmatic patients between 18-64 years old, and randomized them into 2 groups: in the first, patients will receive some workshops about asthma en physical exercise; in the second no educational intervention will be done. All patients will use a step counter in order to evaluate their activity during the study. Spirometric values and questionnaries about asthma control and quality of life will be recorded for all patients. Finally 2 groups will be comparated in order to search any difference in quality of life and asthma control.
NCT06495086
The investigators investigated the efficacy and safety of High Flow Nasal Cannula (HFNC) at different flow rates compared to non-invasive ventilation (NIV) in patients presenting to the emergency department (ED) with acute exacerbations of Chronic obstructive pulmonary disease (COPD) who did not respond adequately to bronchodilator therapy and continued to exhibit hypercapnic respiratory failure. Specifically, the investigators tested the hypothesis that HFNC would be more effective at reducing partial pressure of carbon dioxide (PaCO2) levels and hospital stay duration and would be associated with greater patient comfort than NIV.
NCT04527016

This is a single-center, randomized-controlled trial, the study will compare the management of preschool wheeze determined by airway microbiota phenotype and blood eosinophils level to the management using current clinical guidelines.
NCT05922969
Acute Respiratory distress syndrome (ARDS) is a severe condition in which protective ventilation is a critical point in its management. Positive end expiratory pressure (PEEP) setting can be challenging for clinicians and high PEEP has been associated with better outcome in moderate and severe ARDS. Recently, recruitment to inflation ratio and airway closure have been investigated in order to help PEEP adjustment. However, ventilatory maneuvers are performed with a low level of PEEP and therefore expose to derecruitment and oxygen desaturation. So far, the risk of oxygen desaturation has not been investigated and risk factors are unknown. The aim of this study is to evaluate the prevalence of oxygen desaturation during ventilatory maneuvers at low level of PEEP in patients with moderate or severe ARDS
NCT05566665
Nosocomial Infections (NI) are a common and dreadful complication for patients suffering from Acute Respiratory Distress Syndrome (ARDS) treated with Extracorporeal Membrane Oxygenation (ECMO). Unfortunately, no study has thoroughly evaluated NI in this fragile patient cohort. Newly developed antibiotics may help manage such infections, but their pharmacokinetics (PK) during ECMO has not been evaluated. Objectives of this prospective observational multicenter pharmacological no-profit study are: 1) describe incidence, microbial etiology, and resistance patterns, and assess risk factors for NIs in a large prospective cohort of ARDS patients undergoing ECMO. 2) provide a PK analysis of ceftazidime/avibactam, meropenem/vaborbactam, ceftolozane/tazobactam, and cefiderocol in adult patients undergoing ECMO Incidence, microbial etiology, and antibiotic resistance patterns of confirmed NIs will be prospectively collected and analyzed. In the subgroup of patients treated with ceftazidime/avibactam, meropenem/vaborbactam, ceftolozane/tazobactam, or cefiderocol as per clinical practice, blood and bronchoalveolar concentration of the antibiotic will be measured, and PK modeling carried out.
NCT06488118
Respiratory viral infections can be a cause of significant illness, particularly in vulnerable individuals as seen in the COVID-19 pandemic. An underactive or overactive immune response can lead to ineffective resolution of inflammation after an infection, especially in people with airway diseases such as asthma. A better understanding of immune responses to infection that does not rely on cell or animal models is crucial to help develop better treatments for lung inflammation. An established method of studying inflammation in humans is through careful and controlled exposure (or "challenge") with a mimic of a virus to simulate an infection in a similar manner to that of a virus, but with the advantage of not causing an infection. The investigators have already developed a well-tolerated mimic of human viral infection using a sterile substance called Resiquimod (or R848). Since it does not contain living organisms there is no possibility of being infected. This has been used previously as a nasal spray to cause a mild short-lived inflammation that mimics a mild cold. This has been used safely in a range of people of different ages including those who have asthma. There are differences however in how the nose and lungs respond to viral infections. This is particularly true in those with airway diseases such as asthma, who have cells in the airways of their lungs that respond in a different way to inflammatory triggers (such as viruses). The current study aims to build on previous research by developing a new approach of studying inflammation in the lungs using a small volume of Resiquimod. This will be done by gently inhaling a fine mist through a mouthpiece into the lungs. Blood and phlegm samples would then be collected to assess inflammation and how well people tolerate the procedure.
