Background: Non-invasive ventilation (NIV) reduces respiratory load and demands on peripheral muscles. Methods: This study aims to evaluate the acute effects of bi-level NIV on peripheral muscle function during isokinetic exercise and aerobic performance in chronic obstructive pulmonary disease (COPD) patients. This is a pilot crossover study performed with a non-probabilistic sample of 14 moderate to very severe COPD patients. Procedures carried out in two days. Dyspnea, quality of life, lung function, respiratory muscle strength, functional capacity (6-minute walk test - 6MWT), and isokinetic assessment of the quadriceps were assessed. Blood samples (lactate, lactate dehydrogenase, and creatine kinase concentration) were also collected. Right after, NIV was performed for 30 minutes (bi-level or placebo, according to randomization) followed by new blood sample collection, 6MWT, and isokinetic dynamometer tests. Before and after evaluations, the subjective perception of dyspnea and fatigue in the lower limbs was quantified. After a wash-out period of seven days, participants returned, and all assessments were performed again.
This study aims to evaluate the efficacy and ease of placement of two different endobronchial blockers(Arndt and Tappa blocker) for pediatric patients undergoing thoracotomy. Time from laryngoscopy to successful insertion of the blocker by an experienced anaesthetist will be recorded and the difficulty of placement of the blocker will be assesed. We plan to evaluate the lung collapse and also observe the effect of two different bronchial blockers on patients' ventilation and oxygenation and adverse events such as desaturation, failed one lung ventilation.Our primary outcome is the time from laryngoscopy to successful insertion of the bronchial blocker by an experienced anaesthetist. Our secondary outcomes are effects of two different bronchial blockers on lung isolation score, ease of placement of the bronchial blocker, mechanical ventilation parameters (tidal volume, respiratory rate, peak airway pressure, plateau pressure, compliance), intraoperative blood gas analysis (paO2, pCO2, saO2, lac), frequency of malposition after successful blocker placement, surgical exposure and complications.
Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease, that causes obstructed airflow from the lungs that causes persistent obstructive airflow limitation. Acute exacerbation, especially frequent exacerbation, is associated with an increased risk of death in COPD patients. The most common causes of acute attacks are viral and bacterial infections. This study will assess the efficacy and safety of sitafloxacin, a quinolone antibacterial drug, in participants with AECOPD.
This research is being done to evaluate the feasibility, and biopsy quality, of using a 1.1mm disposable cryoprobe that is passed through the working channel of the Ion Robotic bronchoscope to collect biopsy tissue.
Chronic Obstructive Pulmonary Disease (COPD) affects approximately 16 million Americans and is characterized by recurrent exacerbations that lead to 1.5 million Emergency Department visits and 700,000 hospitalizations annually. Pulmonary rehabilitation (PR) is a structured program of exercise and self-management support that has been proven to relieve shortness of breath and increase quality of life when initiated after an exacerbation, but unfortunately, few eligible patients participate. This project will compare the effectiveness of two novel strategies - one involving video narratives of other patients telling their story of how they overcame challenges and completed PR, the other involving telephonic peer coaching with an individual with lived experience - to enhanced usual care, and to each other, at increasing patient participation in PR after an exacerbation.
The main objective of the study is to evaluate the detection rate of pulmonary conditions, percentage of ionizing radiation dose reduction, and state of image quality of ULDCT coupling with innovative vendor-neutral CT denoising solution based on deep learning technology.
This is a Phase 1b, single center study designed to evaluate the efficacy, safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GSK3923868 following repeat doses in mild asthmatics during experimental human rhinovirus 16 (HRV-16) infection. The study will be conducted in two parts. Part A will determine the efficacy of GSK3923868 administration after viral inoculation (i.e., therapeutic treatment) and Part B may be undertaken to determine the efficacy of GSK3923868 administration before viral inoculation (i.e., prophylactic treatment). The purpose of this study is to establish proof-of-mechanism that GSK3923868 treatment can reduce symptoms of Human Rhinovirus (HRV) infection in a controlled setting.
Background: Pulmonary diseases are significant contributors to morbidity and mortality in patients with rheumatoid arthritis (RA). One of the most common pulmonary manifestation in RA is interstitial lung disease (RA-ILD). Consequently, RA-ILD may be prevalent in approximately 30% and clinically evident in about 10% of RA patients. Since the median survival for patients with manifest RA-ILD is only 6.6 years, feasible methods of detecting early RA-ILD are warranted. Objectives: To determine the diagnostic accuracy of thoracic ultrasound (TUS), using a 14-zone protocol, for ILD in RA patients with respiratory symptoms by using chest high-resolution computed tomography (HRCT) as the reference standard. The secondary aim is to evaluate the diagnostic accuracy for the blood biomarkers surfactant protein-D (SP-D) and microfibrillar-associated protein 4 (MFAP4) in the detection of ILD in this group of patients. Data collection: Participants will be included after signing the informed consent; data will be collected and stored in a REDCap database. Eligibility criteria for participants and settings where data will be collected: Patients eligible for inclusion are consenting adults (≥18 years) diagnosed with RA (according to the 2010 ACR-criteria for RA) and respiratory symptoms indicating RA-ILD, based on the presence of at least one of the following symptoms: unexplained dyspnoea, unexplained cough and/or a residual pneumonia or a chest X-ray indicating interstitial abnormalities in the lung. Whether participants form a consecutive, random or convenience series: Participants form a consecutive series of up to 80 individuals in total. Description of the index test and reference standard: Patients suspected of having RA-ILD will undergo a 14 zone TUS as index test performed by a junior resident in rheumatology, who is certified by the European Respiratory Society in performing TUS assessment. The anonymised images will be stored, and scored by the junior resident and two senior rheumatologists, who have also received training in TUS, as well as a TUS and ILD experienced pulmonologist. Chest HRCT will be the gold standard, i.e. the ILD reference standard. Estimates of diagnostic accuracy and their precision: The two basic measures for quantifying the diagnostic accuracy of the TUS (index) test are the sensitivity and specificity in comparison to the chest HRCT. Statistical tests will be conducted using the McNemar test for correlated proportions.
The aim of this real world study is to assess the safety profile of tiotropium/olodaterol (Tio/Olo).
