Active clinical trials for "Dyspnea"

The purpose of this study is to determine if IMED-4 recordings have sufficient precision to detect a clinically significant change in lung fluid status in acute heart failure syndrome with pulmonary congestion.

Transfusion reactions are defined as harms occurring during or after blood transfusion, with new heart/lung stress (eg. troubled breathing) regarded as cardiorespiratory transfusion reactions (CRTRs). CRTRs are among the most important, as the leading cause of transfusion-related harm and death. Though there are distinct classifications for these events, real life cases often don't fall neatly into a given category, with outliers regarded as "transfusion associated dyspnea (TAD)". It is unknown what TAD is -- whether it has a unique root cause, is a milder version of other known CRTRs, or is a blend of events. The purpose of this study is to better understand TAD and CRTRs by profiling them through a detailed medical history and more intensive laboratory assessment. This review of CRTRs may improve the quality/validity of final conclusions reported in the health record and to hemovigilance bodies, and uncover the nature of TAD and/or minimize CRTRs defaulting to the TAD category. Our enhanced understanding will advance diagnostic, treatment, and prevention efforts.

Discrimination between cardiac and non-cardiac causes of dyspnea can be challenging, causing excessive delay before adequate therapy. In clinical practice lung ultrasound (LUS) is becoming an easy and reliable noninvasive tool for the evaluation of dyspnea and can shorten the time to diagnosis .However the reproductibility of this test was not extensively studied.

The primary aim of this study was to compare patients-rated evaluation and caregiver's assessment of dyspnea with the standard tools in pulmonology unit (Borg scale and visual analog scale) and the secondary aim was to performed an analysis depending on the diseases (lung cancer vs. other lung diseases) and to verify the agreement between the evaluation between both visual analog scale and modified Borg scale.

The Dyspnea-ALS-Scale (DALS-15) is a uni-dimensional scale to measure dyspnea in patients with Amyotrophic Lateral Sclerosis. It can be easily and rapidly applied. The aim of this study is to investigate reliability and validity of Turkish version of the DALS-15.

This study assesses the potential of lung ultrasonography to diagnose heart failure.

The purpose of this study is to create a prospective database of all patients who have undergone pulmonary function testing from which the investigators can study the clinical phenotypes of various respiratory conditions. The investigators hope by understanding the differences in these myriad phenotypes to be able to provide individualized, patient-targeted therapy in the future.

Dyspnea is a frequent symptom in patients admitted to the Emergency Department (ED); discriminating between cardiogenic and non-cardiogenic dyspnea is a common clinical dilemma. The initial diagnostic work-out is often not very accurate in defining the etiology and the underlying pathophysiology. In the last years, lung ultrasound (US) has emerged as a useful real-time bedside diagnostic tool in the critical patient. The aim of this study was to evaluate the accuracy, reproducibility, and diagnostic impact of pleural and lung US, performed by emergency physicians at the time of patient first presentation to the ED, in identifying cardiac causes of acute dyspnea.

This research aims to improve our knowledge of the epidemiology of patients consulting in the COvid-19 Possible REspiratory Units (RECOP unit). Indeed, the epidemic linked to COVID-19 affects France and impacts its health system. The reception of all intermediate patients will be on the Emergency Structures (SU). Indeed, the French healthcare system centralizes unscheduled urgent care on the ER. The aspecific respiratory symptomatology in "intermediate" patients indicates them all the more at an admission to SU or the diagnostic approach to respiratory difficulty may be carried out. A central issue of this diagnostic strategy will be to be rapid, since the diagnosis will have to be made in the context of significant flows, with a need to quickly refer patients to the most suitable downstream service, while limiting the risk contamination of caregivers and vulnerable patients if a COVID-19 + patient is admitted to an unsuitable service. However, virological tests do not currently allow rapid results for COVID-19. Research project of investigatory aims to develop a predictive model of the risk of being COVID-19 positive for patients admitted to the emergency room for acute dyspnea.

Brief Summary: The aim of this study is to analyze in elderly patients with undifferentiated dyspnea, the concordance of diagnosis before and after a focus thoracic ultrasound in comparison with the reference one established by an adjudication committee
