Filter by:This study investigates the efficacy of different anesthesia methods (general anesthesia with laryngeal mask airway and local nebulized anesthesia) for transbronchial biopsy using an electronic bronchoscope. The study retrospectively analyzed cases of transbronchial biopsy performed at the Respiratory Endoscopy Center of Sichuan Provincial People's Hospital from June 5, 2020, to June 5, 2024. Data collected included age, gender, primary diagnosis, anesthesia method, biopsy method, operation time (excluding general anesthesia and laryngeal mask airway placement time), lesion location and size, pathological results, and follow-up status.
Respiratory diseases are very common and are the third leading cause of death in England. As such, there is strong interest in understanding how respiratory disease occurs. This study intends to understand the changes that occur within diseased/injured lungs obtained from humans. The end goal of this will be to create new drugs to help treat these disorders. Diseased lungs will be obtained from patients receiving a lung transplant. Lungs will either be placed onto a heart-lung machine, or surgically cut in order to create a model of the lung that can be used experimentally in the laboratory. Using a heart-lung machine, lungs can be maintained outside of the human body for a maximum of 12 hours, allowing the direct assessment of the organ. Using this procedure, we aim to understand the processes that occur within a disease, as well as during repair. Using the model of the lung, we will look at how the body's immune system interacts within a diseased lung.
The objective of the present study is to evaluate the effectiveness of daily consumption of a Combination of Plant Extracts (BSL_EP027) on the incidence of respiratory infection symptoms and their duration in older healthy volunteers living in a nursing home.
The goal of this study was to identify the etiology of events and demographics of patients that experience complications requiring activation of the Rapid Response Team (RRT) during the first 24 h following anesthetic care.
To investigate the efficacy and safety of using the novel Tyto device for remote physical examination by co-investigators as compared to a standard medical physical examination by physicians.
The environmental pollutants and endogenous reactive oxygen metabolites from inflammatory cells exert substantial pathological effects on the lung cells [1]. Oxidative stress (OS) is a major factor that plays a significant role in lung cancer (LC) [2], chronic obstructive pulmonary disease (COPD) [3] and obstructive sleep apnea syndrome (OSAS) [4, 5]. The current evidence suggests that OS takes part in the mechanisms involved in initiation, promotion and progression of respiratory diseases. The major exposures that cause OS can be summarized as smoking, and ambient air pollution that contains particulate matter smaller than aerodynamic diameter of 2.5 µm [6-8]. Epidemiological and clinical studies showed that the overall outcome of pulmonary OS is increased mortality due to increased incidence of respiratory diseases [9].
Using an adult lung bench model of non invasive ventilation, the aim of the study is to compare an experimental system of breath-synchronized vibrating mesh nebulizer to a conventional vibrating mesh nebulizer during non invasive ventilation in terms of inhaled and lost doses.
Several studies show an association between chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD). Besides risk factors such as smoking, both are associated with physical inactivity, advanced age and systemic inflammation The use of coronary computed tomography (CCT) with multiple detectors is a diagnostic method for coronary disease, describing the anatomy and severity of arterial obstruction. One way of estimating the cardiovascular risk is coronary calcium score (CCS). Due to the association between COPD and CAD, it is likely that many patients with IHD diagnosed by CT have reduced lung function. The aim of this observational study is to establish the correlation between the CCS and lung function. It will also correlate the presence of irreversible airway obstruction with significant coronary lesions. Patients over 40 years referred to CCT who agree to participate in the study will perform a spirometry with bronchodilator and collect a blood sample to measure serum markers of inflammation and cardiovascular risk (glycemia, lipid profile, C reactive protein (CRP), tumor necrosis factor-alpha (TNF-Alpha) and fibrinogen). The data will be compared in the general population and in subgroups: smokers, former smokers and nonsmokers. One year after the CCT patients will be contacted by the investigators and accessed for emergency room visits, hospital admissions and fatal or nonfatal coronary or respiratory events. The investigators hypothesis is that reduced lung function is independently associated with elevated CCS and is, also a risk factor for increased hospital admission and coronary events. The concomitant assessment of lung function and CCS can contribute knowledge about the epidemiological association between pulmonary disease and CAD. This can also add to evidence for the use of spirometry as a marker of cardiovascular risk.
The purpose of this study is to investigate the effect of AZD5069 in patients with bronchiectasis.
1. Aim: The aim of the clinical trial is to study the accuracy of the TensorTip device compared with registered (FDA-approved) invasive and non-invasive devices. 2. Hypothesis: Human physiological biomarkers may be measured from the color distribution of the internal or external (skin) tissue. The technology of the TensorTip finger-mounted device is based on the color distribution of the peripheral blood tissue, which enables the measurement of certain biomarkers and vital signs under consideration.
