Filter by:The main objective of this study is to determine if the systemic (intravenous) administration of corticosteroids, as compared to placebo, increases the number of ventilator-free days (VFD) and alive at day 28 in COPD patients admitted to an ICU, a step-up unit or a respiratory care unit for an ACRF requiring ventilatory support, either invasive or non-invasive.
To develop, using barcode systems and virtual pillbox (TuMedicina and Alice), an App aimed at patients and carers of patients with cardiometabolic diseases as the main diagnosis, over 45 years of age, who have one or more pathologies and use one or more drugs on a daily basis and to analyze their effectiveness in terms of achieving therapeutic objectives, self-efficacy and self-efficacy in self-care or provision of care (as the case may be), healthy behavior, therapeutic compliance and safe use of medication.
The aim of this study is to investigate the use helmet ventilation (HV) in walking test and analysis of effect patients with COPD.
High-flow nasal cannula oxygen therapy(HFNC) has proved no significant difference compared with noninvasive positive pressure ventilation (NPPV) in preventing postextubation respiratory failure and reintubation in patients with acute hypoxemic respiratory failure.However, the efficacy of early postextubation sequential HFNC in COPD patients with hypercapnic respiratory failure is inconclusive.
Despite the high burden of respiratory symptoms in the HIV+ population, causes of chronic obstructive pulmonary disease (COPD) in individuals with HIV are poorly understood. Microbial communities present in the lungs or gut could play an important role in COPD via their ability to stimulate inflammation and oxidative stress and by the interactions of microbial and host gene transcription. By exploring the impact of the structure and function of microbial communities on the host in HIV-associated COPD, this project could lead to discovery of novel therapeutics to treat and prevent COPD. Subjects will be 20 HIV+ individuals with COPD (FEV1/FVC <0.70 and FEV1 and DLco<80% predicted) and 20 HIV+ individuals with normal lung function (controls) and 10 HIV negative individuals recruited from our ongoing cohorts. Controls will be matched to the individuals with COPD based on age, gender, pack-years of smoking, ART use, HIV viral suppression, and history of illicit drug use. Bronchoscopy will be performed on all subjects. The investigator will uncover mechanisms that contribute to COPD in HIV+ individuals, which will lead to interventional therapies. For example, the investigators evaluate the impact of bacteria on lung epithelial cell gene expression and inflammation and test ability of anti-inflammatories to alter responses. Identification of other key pathways or microbes could also lead to testing of pro-biotics, post-biotics (bacterial metabolites), or therapy with bacteria genetically modified for desired function or metabolites.
A clinical study to investigate if a single dose of an approved drug product (glycopyrrolate Inhalation Solution) reduces trapped air in the lungs of participants with chronic obstructive pulmonary disease. This study is accepting male and female participants over the age of 40. The study will be conducted at one site located in the United States.
This is an 8-week randomized controlled trial to help address health, resilience, and well-being. Participants are randomized into either a health education group or an arts-based health education group. Both groups will attend for 8 weeks and various study assessments will be conducted in order to measure the experience and impact of the program. Anyone 18 years and older with a chronic health condition (for example, diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disorder, asthma, weight, anxiety, depression, cardiac, arthritis, multiple sclerosis, and many more) are eligible to participate.
Peripheral muscle weakness is a predominant problem in patients with COPD and treated using exercise training in pulmonary rehabilitation. Despite pulmonary rehabilitation being an effective intervention, muscle strength impairment is a persisting problem in COPD patients. Patients have problems to tolerate the high training loads, which are necessary to develop strength. Low-load blood flow restriction training (LL-BFRT) might therefore be an option to enhance muscular response of patients with COPD to strength training. Up to now, no studies investigating LL-BFRT in respiratory diseases are available. The primary outcome of this randomized pilot study is knee extensor muscle strength. Secondary, the study will evaluate if LL-BFRT is well tolerated and feasible in COPD patients attending outpatient pulmonary rehabilitation.
Elastosonography is an advanced ultrasound technique, nowadays available in many portable systems, allowing to measure elasticity and stiffness of parenchymatous organs. Its main current applications concern the advanced diagnostics of liver, thyroid and breast nodules. Few studies have applied elastosonography to the respiratory system, and to date no-one has evaluated the elasticity of lung parenchyma in COPD and only one in pulmonary fibrosis. The primary aim of this study is to compare the elasticity features of lung parenchyma, measured by bedside ultrasound integrated with ultrasonography, among three groups of subjects: 1. patients with COPD and/or lung fibrosis; 2. smokers with no functional evidence of COPD or fibrosis; 3. healthy non-smoking volunteers. The secondary aim is to verify the possible correlation of elastosonography-related parameters of lung elasticity/stiffness with results of lung function tests. One hundred and thirty-eight subjects (46 per group) will be enrolled in this experimental study, on both inpatient and outpatient basis. The presence or absence of COPD or fibrosis will be assessed integrating personal history, imaging tests and functional tests prior to enrolment. Smoking habits will also be carefully investigated. Excluded from the study will be all subjects with acute COPD flares, acute respiratory failure, inability to undergo lung ultrasound examination and lung function tests, cognitive impairment, severe motoric disability, cancer, poor survival prognosis. Each participant will undergo standard lung function tests and bediside ultrasound examination integrated with lung elastosonography during the same day. Lung function tests will be performed with a Carefusion MSC Body spirometer following standard procedures. Lung ultrasound will be performed by a skilled physician, using the convex probe of an Esaote Mylab Seven ultrasound system (Esaote, Genova, Italy), equipped with strain elastography module ElaXto©. The participant will remain in the sitting position for the whole ultrasound/elastography procedure, with the examiner systematically scanning intercostal spaces on both sides of the back thorax. After performing a standard lung ultrasound scan to verify the absence of consolidations or signs of respiratory diseases other than COPD, the examiner will activate the elastography module, performing little compressions with the wrist on the convex probe, to obtain adequate elastography images combining ranges of red, green and blue colors. Images will then be analyzed with the software ElaXto©, to obtain the percentage of stiffness in areas of interest of lung parenchyma. Statistical analyses will be focused on comparison of stiffness index across different groups, and on correlation of elastosonographic parameters with lung function tests (FEV1, Tiffeneau index).
The study will characterise inspiratory flow parameters across placebo dry powder inhaler Easyhaler (2 inhaler versions) and placebo Spiriva inhalation powder capsule inhaled via HandiHaler in patients with chronic obstructive pulmonary disease (COPD) and in healthy volunteers. Substudy: Easyhaler® and HandiHaler® Usability study in patients with COPD; to assess patients acceptability, preference, correct use and ability to learn to use Easyhaler and HandiHaler (with capsules) and to compare PIF rate via In-Check Dial meter with the PIF rate via spirometer in the main study.
