Filter by:Single-centre prospective study to characterize causes of dyspnea in stable patients with coronary artery disease and evaluate the possibility to determine the cause of dyspnea before in-depth examination.
To improve the safety of diagnosis and therapy for a set of conditions and undifferentiated symptoms for hospitalized patients, the investigators will employ a set of methods and tools from the disciplines of systems engineering, human factors, quality improvement,and data analytics to thoroughly analyze the problem, design and develop potential solutions that leverage existing current technological infrastructure, and implement and evaluate the final interventions. The investigators will engage the interdisciplinary care team and patient (or their caregivers) to ensure treatment trajectories match the anticipated course for working diagnoses (or symptoms), and whether they are in line with patient and clinician expectations. The investigators will use an Interrupted time series (ITS) design to assess impact on diagnostic errors that lead to patient harm. The investigators will perform quantitative and qualitative evaluations using implementation science principles to understand if the interventions worked, and why or why not.
The general aim of this study is to estimate the rate of disease progression for adults testing positive for SARS-CoV-2. The primary endpoint for this study and the basis for sample size is hospitalization or death during the 28 day follow-up period. In some locations special facilities are being built/utilized for quarantine/public health reasons for those who are SARS-CoV-2 positive. Hospitalization is defined as a stay for at least 18 hours, irrespective of reason, at a hospital or one of these special facilities after study enrollment. Secondary outcomes include participant-reported health status and change in severity of dyspnoea.
This was a randomized, multi-center, open-label clinical trial. Eligible patients were recruited from seven hospitals in China. On the basis of standard-of-care, patients in treatment group inhaled H2-O2 (66% hydrogen; 33% oxygen) at 3 L/min via nasal cannula by using the Hydrogen/Oxygen Generator (model AMS-H-03, Shanghai Asclepius Meditech Co., Ltd., China) until discharge. Patients in control group received standard-of-care (consisting of oxygen therapy) alone until discharge.
Chronic Obstructive Pulmonary Disease (COPD) is associated with high morbidity and mortality. The Danish Lung Association estimates that 320,000 Danes live with COPD, of which approximately 50,000 with severe COPD. In 2017, records showed that 23,979 admissions in Denmark were related to COPD; of these patients, about 20% were readmitted 2-30 days after discharge. The main symptom is dyspnea, which is often accompanied by anxiety. Primary treatment is; oxygen, bronchiolitis, prednisolone, morfin, NIV, and anxiolytics. Researchers at Hvidovre Hospital have developed an oxygen robot that continuously monitors the patient's SaO2 (oxygen saturation) and automatically administrates the oxygen depending on it. The preliminary results show that patients with robot-administrated oxygen were within defined SaO2 range in 85.7% of the time versus 46.6% when oxygen was nurse-administrated. The research was conducted as a multicentre Randomized Controlled Trial (RCT)focusing on physiological end-points. There is a lack of knowledge about the patient perspective of treatment with the oxygen robot. The purpose of this study is: 1. To examine the association between robot-administered oxygen and patients' perception of dyspnoea, including the emotional response in the form of anxiety and depression The perspective is to be able to provide a holistic response to whether robot administered oxygen can be a better method of treating and alleviating dyspnoea.
The purpose of this study is to evaluate the effectiveness of two different ways to teach hospitalized children how to use a metered dose inhaler and to follow-up after discharge home from the hospital to determine durability of the education.

Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
This study evaluates a pharmacological intervention to relieve dyspnea in intensive care unit patients. Indeed, opioids can be particularly beneficial since 1) dyspnea and pain share many similarities, 2) the benefit of opioids on dyspnea has been clearly demonstrated in other populations. However, to date, data regarding the impact of morphine on dyspnea in intensive care unit patients admitted for acute respiratory failure are scarce. There may be a reluctance of physicians to prescribe opioids that is not scientifically justified. The study will focus on patient reported outcome (PRO) criteria. The ultimate goal of this pilot study is to design the protocol of a future pragmatic trial.
Dyspnea; subjective experience of respiratory discomfort; which produces negative emotional experience, is the most common symptom of patients afflicted with chronic respiratory failure and its treatments are limited. Amyotrophic Lateral Sclerosis (ALS) related - dyspnea, due to diaphragmatic dysfunction, is similar to dyspnea during mechanical inspiratory load (activation of the supplementary motor area, SMA). The perception of pain and dyspnea is processed in similar brain areas (insula, dorsal anterior cingulate cortex, amygdala and medial thalamus) and in ALS; relieving dyspnea by noninvasive ventilation (NIV) is associated with decreased pain thresholds. Otherwise, it is reported systemic elevations of pro-inflammatory cytokines in chronic pain patients, correlating with intensity of pain, and during respiratory load in healthy volunteers. The objectives are to evaluate the cytokines and endorphins rates variations after initiation of NIV in ALS patients, and to correlate cytokines and endorphins rates with the intensity of the affective component and the intensity of the sensory component of dyspnea. The investigators will perform a prospective, experimental study, including 30 ALS patients. Dyspnea, ventilatory and cardiac settings, electromyographic recording of the scalene muscle and biological assays (ACTH, endorphin, Neuropeptide P, BDNF, IL1, IL6, IL8, IL10, TNF), will be measured during spontaneous breathing and during NIV at different times after initiation. The investigators expect a reduction of immunological and neurobiological markers after relieving dyspnea by NIV. This work could lead to the development of new treatments for dyspnea.
