Filter by:LEDA (Lithuanian Echocardiography study of Dyspnea in Acute settings) is a prospective observational cohort multicenter clinical study. Project is carried out by Vilnius University together with a partner Lithuanian University of Health Sciences, in conjunction with a research protocol of international GREAT consortium (Global Research on Acute Conditions Team). The aim of this project is to find the specific novel biomarkers of acute heart failure (AHF), to evaluate their diagnostic and prognostic role in association with echocardiographic parameters of AHF. Primary endpoint is 1-year all-cause mortality and rehospitalization. Secondary endpoints are 1) in-hospital all-cause mortality 2) post-discharge 1 and 3 month all-cause mortality and rehospitalization 3) post-discharge 1 and 3 month cardiovascular mortality and rehospitalization 4) one-year cardiovascular mortality and rehospitalization. During the project a sizeable national database (2000 Lithuanian patients) will be integrated into database of GREAT network. Novel cardiac biomarkers together with ultrasound parameters of right ventricular (RV) function are in the focus of the study. During the acute phase of heart failure, up to 15 novel cardiac, vascular, renal impairment and inflammation biomarkers in plasma samples will be investigated in Lithuania and France (INSERM laboratory). Plasma samples will be taken during 4 hours after admission and frozen at -80ºC to allow batch analysis. The extensive evaluation of innovative ultrasound parameters of right ventricular structure and function will be performed in the early hospitalization period, along with standard echocardiography examination. The first database of AHF patients in Lithuania will provide demographic data and trends of morbidity and mortality, as well as analysis of diagnostic and prognostic value of novel biomarkers and echocardiography parameters in the Baltic region. Quantitative parameters of RV systolic function and deformation will be measured. It is expected that optimal use of novel biomarkers and reproducible echocardiography parameters in the setting of emergency and critical care would reduce unnecessary hospitalizations, cost and hospital length of stay without decrease in the quality of diagnostics and treatment. An estimation of correlation of echocardiographic parameters and biomarkers could help create an accurate algorithm for risk stratification and diagnosis of AHF in an emergency setting.
Dyspnea is a common complaint in obese patients. The mechanisms behind this dyspnea and the effects of weight loss on dyspnea are not completely understood. The objectives of this study were to examine the relationships between exercise parameters and dyspnea in obesity and assess the effects of weight loss. The investigators compared pulmonary function, exercise performance and dyspnea in 34 patients with abdominal obesity and metabolic syndrome (MS) against 34 age and sex-matched controls. The study also assessed within-group changes in physiology and symptoms in a subset of patients following participation in a weight management program. Because obesity is a heterogeneous condition, with variable genetic associations, co-morbidities and distributions of adipose tissue, the study focused on patients with abdominal obesity who met diagnostic criteria for metabolic syndrome.
Patients with interstitial lung disease (ILD) experience distressing activity-related respiratory discomfort which is challenging to manage therapeutically. Interventions such as pulmonary rehabilitation, collaborative self-management, supplemental oxygen therapy and oral opiate medications, are variably effective and therapeutic responses to each in individual patients are difficult to predict. The purpose of this study is to evaluate the acute effects of inhaled opiate therapy (fentanyl citrate) on breathing discomfort (dyspnea) in individuals with mild-to-moderate ILD, as well as examine the potential mechanisms of dyspnea relief.
The purpose of this study is to learn more about new noninvasive ways of detecting lung disease in US Military personnel and people who worked as contractors during military operations in Iraq and Afghanistan. This study is looking at conducting a type of breathing test called the lung clearance index (LCI) test which is being investigated as a potential noninvasive way to detect the type of lung disease that may be seen in symptomatic deployers retuning from Iraq and Afghanistan.
Effects of Qigong on symptom clusters of dyspnea, fatigue, and anxiety in Vietnamese lung cancer patients: A randomized control trial
The objective of this study is to look at the effects of distractive auditory stimuli (DAS) on reducing dyspnea intensity and related anxiety and increasing exercise tolerance. Investigators hope that compared to a no-music control condition, that under a music condition participants with COPD will (a) demonstrate increased self-paced walk distance and enjoyment; (b) have less dyspnea intensity, (c) experience less dyspnea anxiety; (d) have less fatigue and state anxiety; and (e) higher maximum heart rate. The upbeat music with a tempo of 90 - 100 bpm (an average-to-moderate walking tempo) is expected to have distractive and performance enhancing effects in order to increase tolerance to dyspnea and exercise. The long-term goal of this study is to increase physical activity in adults with COPD and RLD by promoting dyspnea and fatigue management through use of distractive auditory stimuli in the form of music.
Post-operative pulmonary complications (PPCs) have a major impact on patients and healthcare expenses. The goal of perioperative respiratory therapy is to improve airway clearance, increase lung volume, and mitigate atelectasis. Incentive spirometers (IS) are ubiquitously used to prevent atelectasis and PPCs—implementation of which requires substantial provider time and healthcare expenses. However, meta-analyses have demonstrated that the effectiveness of ISs is unclear due to poor patient compliance in past studies. The goal of this investigation is evaluate the effectiveness of IS on post-operative clinical outcomes. The aims of this investigation are to evaluate 1) if IS use compliance can be improved by adding a use-recording patient reminder alarm, and 2) the clinical outcomes of the more compliant IS users vs. the less-compliant IS users.
The goal of this clinical research study is to compare high-flow oxygen, low-flow oxygen, high-flow air, and low-flow air in helping to decrease shortness of breath in cancer patients. Researchers also want to learn if these therapies can help to improve lung function and quality of life.
This study evaluates the effect of inhaled furosemide on different types of breathlessness relief in healthy volunteers. Each volunteer inhaled mists of either furosemide or a control substance on 3 occasions per day on 2 separate days. On one day they performed one breathlessness test which creates an 'urge to breathe' known as air hunger (AH) and the other day they performed a breathlessness test which increases the sense of work/effort (WE) of breathing. The study is double blinded so neither the volunteer or the research knows which mist is being inhaled.
