Filter by:The project will be pursued in our respiratory, autonomic nervous system physiology laboratory (Respiratory, autonomic nervous system physiology laboratory, Department of Pneumology and Intensive Care Medicine, RWTH Aachen University Hospital; Head of Department: Professor Michael Dreher). Overactivity of the sympathetic nerve activity (SNA) axis with "centrally" increased heart rate and peripheral vasoconstriction is a known phenomenon in patients with systolic heart failure (HF) and has recently been described in patients with primary lung disease as seen in chronic obstructive pulmonary disease (COPD). However, systematic analyses on this clinically relevant topic are currently lacking. Thus, using a comprehensive, multimodal approach and state-of-the-art technology, this research project is designed to determine the extent and nature of increased SNA in COPD (AIM 1) and evaluate the underlying mechanisms (AIM 2). The project will address the following hypotheses: 1. In COPD, concomitant obstructive sleep apnea is independently associated with increased SNA. 2. Precapillary pulmonary hypertension (PH), inspiratory muscle dysfunction and systemic inflammation describe a COPD phenotype characterised by increased SNA with a different subtype.
This is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict the likelihood of 30-day readmission throughout a patient's admission. This algorithm was then validated in a validation cohort.
This study will last for 5 years (2021.2.25-2025.12.31). 210 patients (70 cases in each group) will be enrolled in this study. Eight centers in China will participate in the study. The patients will be treated with bronchoscopy alveolar lavage, and 60 ml of bronchoalveolar lavage fluid will be collected for the next-generation sequencing of airway microorganisms. The patients will be followed up for 4 years to observe the changes of lung function, Fractional exhaled nitric oxide (FENO) and clinical symptoms.
Patients with chronic obstructive pulmonary disease (COPD) can eventually progress to respiratory failure, where they cannot adequately exchange oxygen and carbon dioxide, leading to worsening breathlessness, frequent hospitalisations and death. Non-invasive ventilation (NIV) is a ventilator therapy that is used in COPD patients who suffer from respiratory failure. Studies have demonstrated that using NIV at night regularly can result in improved clinical outcomes. Adherence to this therapy is variable, however. This can be due to poor synchrony between the device and the lungs. A novel ventilator has been designed that delivers NIV but is also incorporated with technology to assess for aberrations in respiratory physiology and correct them, breath-by-breath. The investigators aim to assess the efficacy, safety and tolerability of this novel ventilator. The primary research question is whether the novel ventilator can improve adherence to therapy, when compared with the usual ventilator. Patients with COPD who use ventilation at home will be screened for inclusion in the study. Participation will involve a screening visit, and a further two visits to the Lane Fox Respiratory Unit. The first will require a two-night admission and the second a single-night admission. They will undergo detailed assessment of their daytime and overnight respiratory and sleep physiology during these admissions. These visits will be separated by a six-week period during which they will be asked to use the novel ventilator at home. Patients will be recruited into a sub-study to evaluate the performance of the ventilator in a daytime physiological assessment. This will involve detailed invasive physiological assessment of expiratory flow limitation and how the machine is able to adjust settings to optimise respiratory support.
To Evaluate the Outcome of cardio selective beta1 (β1-) blockers use in patients with chronic obstructive pulmonary disease. Patient education about the COPD and their medications.
This investigator-initiated, prospective, single center, randomized, controlled clinical trial enrolled patients with stable Global Initiative for Chronic Obstructive Lung Disease stage II-IV chronic obstruction pulmonary disease. The primary outcome was 2-year acute exacerbation rates.
Purpose: The purpose is to determine the effect of therapeutic touch on the sleep quality and anxiety of individuals with chronic obstructive pulmonary disease. Material and methods: This study was conducted between March 2018 and March 2019 as a randomized controlled experimental study conducted with pre-test post-test model. In addition to the routine nursing care, therapeutic touch (TT) and study scales were applied to the experimental group for a total of three sessions, once a day and 10 minutes each, for three consecutive days and only study scales were applied to the control group. The data was collected using Personal Information Form, Richard-Campbell Sleep Questionnaire and State Anxiety Inventory.
COPD is a progressive disease associated with systemic inflammation, with many extrapulmonary outcomes such as cognitive impairment. Most of the daily activities involve doing several tasks at the same time, such as walking while talking or avoiding obstacles.
The aims of the study are to compare long-term one-year outcome with or without AirvoTM in stabile hypercapnic COPD patients, who are non-compliant to NIV after an acute exacerbation of COPD.
To investigate the relation the nreural drive and intrinsic positive end-expiratory pressure(PEEPi) of the chronic obstructive pulmonary disease(COPD) patients with respiratory failure.In present study the PEEPi of COPD patients was increased by increasing the resistance of the respiratory system, the change of the neural drive was recorded.
