Active clinical trials for "Lung Diseases"

COPD causes an acute deterioration of respiratory symptoms, particularly increased breathlessness and cough, and increased sputum volume and/or purulence. Worsening airflow limitation is associated with an increasing prevalence of exacerbations and risk of death. These exacerbations can range from self-limited diseases to episodes of florid respiratory failure requiring mechanical ventilation .Hospitalization for COPD patients post COVID is associated with poor prognosis with increased risk of death. Hence techniques of efficient clearance of peripheral airways may reduce airway occlusion by excess mucus and inflammatory cells, improving lung function, exercise capacity and reducing exacerbation frequency.

Previous studies have shown the feasibility of ERAS on minimally invasive lung surgery, but it is unknown whether completely tubeless protocol is safe and better. This study aimed to determine whether completely tubeless protocol is feasible and beneficial for minimally invasive lung surgery, compared with partially tubeless protocol.

This study is a randomized controlled trial (RCT) to compare sleep and health-related functioning in Veterans with chronic obstructive pulmonary disease (COPD) and insomnia receiving an Internet-based behavioral treatment for insomnia during home-based pulmonary rehabilitation (HBPR) versus those only receiving HBPR. Participants will undergo a sleep and health assessment that will be performed prior to the beginning of HBPR and at the end of HBPR and 6-months later. Participants will be randomly assigned to either Internet-based behavioral treatment for insomnia plus HBPR or HBPR only.

The goal of this physiological interventional prospective study is to evaluate the improvement of the previously demonstrated correlation between PaO2/ FiO2 and Lung Ultrasound score (LUSS) in patients admitted in the ICU with an intesrtitial syndrom (IS) on the ultrasound of all aetiologies at inclusion and at twenty four and forty eight hours. The main question it aims to answer is if the LUSS is a valid tool to evaluate the severity of the IS Participants will initially have an arterial blood gas to evaluate the PaO2/FiO2 and in the ten minutes a lung ultrasound to evaluate the LUSS. This will be repeated at twenty four and forty eight hours.

Patients undergoing major head and neck surgery are at risk for postoperative pulmonary complications. The goal of this randomized clinical trial is to evaluate the effectiveness of high flow heated humidified oxygen at preventing postoperative pulmonary complications after major head and neck surgery, when compared to conventional oxygen therapy (aerosol cool mist).

Cough is the most unwanted response during bronchoscopic interventions for hemodynamic instability, hypoxemia, and interruption of interventions. Topical lidocaine is recommended with a grade evidence in British Thoracic Society guideline. However, severe cough often induces during the initial bronchoscopic spraying of local anesthesia, follows with uneven spraying, spasm or arrythmias. In previous reports, there were many drugs and techniques investigated for preventing cough during broncoscopic spraying. As bronchoscopic interventions need more space and stability of airways to precisely operate on, few studies have focused on the effects of different drugs for preventing cough. In this study, Different intravenous drugs (lidocaine, alfentanil, compared to normal saline) is planned to be injected one minutes before bronchoscopic insertion, the responses to bronchoscopicly spraying local anestheticsuch as cough intensity, BIS levels, ANI, Transdermal O2 and CO2, respiration were recorded and analyzed.

Chronic obstructive pulmonary disease (COPD) is presently the third leading cause of death worldwide and is characterized by irreversible airflow limitation diagnosed by spirometry. COPD is currently considered as a systemic disease with predominantly respiratory involvement, associated with numerous comorbidities. Among these, muscle wasting, present in about one third of patients, is associated with a higher mortality (up to 10-fold, irrespective of the severity of the obstruction). Muscle wasting is classically characterized by a decrease in muscle strength and volume (sarcopenia), which can be defined by a decrease in the muscle mass measured by dual X-ray absorptiometry: Appendicular Skeletal Muscle Mass or ASM / height < 7.0 kg/m2 in men and 5.5 kg/m2 in women. However, sarcopenia is largely underestimated in current clinical practice. Moreover, there is no specific treatment: only exercise training as part of respiratory rehabilitation has shown some efficiency. The underlying pathophysiological mechanisms are indeed poorly characterized. Fibrocytes, cells derived from blood monocytes and able to migrate to different organs in order to play pro-fibrotic or pro-inflammatory roles, play a key role in bronchial obstruction. They are recruited in the blood of COPD patients during an acute exacerbation according to a CXCL12/CXCR4 chemotactic axis. Their role in COPD sarcopenia is currently unknown, but recent data show that they are involved in a mouse model of muscular dystrophy. The hypothesis is that fibrocytes are involved in COPD sarcopenia.

Respiratory muscle testing allows a quantitative assessment of inspiratory and expiratory muscles in children of any age with primary or secondary respiratory muscle impairment, in order to better understand the pathophysiology of respiratory impairment and guide therapeutic management. The use of an invasive technique (esogastric probe) makes it possible to specifically explore the diaphragm, the accessory inspiratory muscles and the expiratory muscles in order to detect dysfunction or paralysis of these muscles, and to estimate the work of breathing in order to better guide the respiratory management. The primary objective of the study is to evaluate the respiratory effort in children with primary or secondary impairment of the respiratory muscles during spontaneous breathing or during mechanical ventilation.

The purpose of this study is to develop and evaluate the usefulness of MRI using 129Xe gas for regional assessment of pulmonary function. Specifically, three forms of 129Xe MRI contrast will be the investigators focus - 1) imaging of the 129Xe ventilation distribution, 2) imaging the alveolar microstructure via the 129Xe apparent diffusion coefficient (ADC), and 3) imaging 129Xe that dissolves in the pulmonary blood and tissues upon inhalation. Such imaging of 129Xe gas transfer is expected to be uniquely sensitive to pathologies affecting gas exchange (fibrosis, emphysema, pulmonary hypertension) and provide new insights regarding the normal resting heterogeneity of pulmonary gas exchange.

The purpose of this study is to find out if an investigational combination drug called Lovaza (made with fish oils)+Curcumin C3 Complex (made from a root called curcumin) can help reduce the size of lung nodules. Researchers also want to find out if the combination of Lovaza+Curcumin C3 Complex is safe and tolerable.
