Active clinical trials for "Dyspnea"

This study will be conducted in order to examine the effect of prayer to individuals with COPD on the severity of dyspnea, anxiety and spiritual well-being experienced by patients.

Aim of this multicenter prospective cohort study is the evaluation of the multidimensional qualities of dyspnea in a number of diseases using the Multidimensional Dyspnea Profile (Banzett et al, ERJ 2015).

To evaluate the role of exercise hemodynamic testing in the diagnostic workup for patients with dyspnea on exertion referred to the catheterization lab.

Background: Acute dyspnoea is a common symptom in prehospital emergency medicine. As ultrasound gained in importance for diagnosis in patients with acute respiratory distress, it plays even a role in the prehospital setting. However, prehospital emergency ultrasound (PEU) remains challenging and requires knowledge and skills. New prehospital ultrasound devices offer the possibility for tele-supervision. The impact of tele-supervision of PEU in patients with acute dyspnoea is unclear. Objective: This prospective observational study aims to evaluate the effect of PEU with tele-supervision on diagnosis, treatment strategies and cognitive load in comparison to PEU without tele-supervision in patients with acute dyspnoea. Methods: In total 350 prehospital emergency patients with acute dyspnoea will be included in this study. Patients will be observed in two groups. In group 1 PEU will be performed with tele-supervision, whereas in group 2 PEU will be performed without tele-supervision (tele-supervision not available).

Autophagy is considered an important component of Heart failure progression. Deubiquitination enzymes play an important role in autophagy. An important regulatory process within the autophagy pathway is ubiquitination. Ubiquitination targets proteins for degradation. On the contrary, de-ubiquitinating proteins (such as UCHL1) reverses this process. Studies have demonstrated deubiquitination to be linked to certain pathological processes, such as heart failure. UCHL1 will be examined as a potential marker of disease progression in acute decompensated heart failure.

Chronic and progressive dyspnea is the most characteristic symptom of chronic obstructive pulmonary disease. There are studies in the literature showing that electromyography activations of respiratory muscles increase in individuals with chronic obstructive pulmonary disease and that the severity of the perceived shortness of breath is associated with muscle activation. However, no study has been found comparing respiratory muscle activations during pursed lip breathing and normal breathing in the dyspnea reduction positions and supine position used in the treatment and management of chronic obstructive pulmonary disease. The aim of this study is to evaluate the effects of different dyspnea reduction positions on respiratory muscle activations separately, to compare respiratory muscle activation during normal breathing, respiratory control and pursed lip breathing during these different positions, and to classify muscle activations according to the severity of chronic obstructive pulmonary disease.

COVID-19, a novel coronavirus, has caused widespread mortality and morbidity since it emerged in 2019. There is ongoing research and growing literature describing severe acute respiratory syndrome (SARS-COV-2). There is a growing population of individuals who have recovered from acute SARS-COV-2 infection. The long-term effects of COVID-19 are unknown. There are growing reports of sequelae after acute SARS-CoV-2 not limited to fatigue, dyspnea, reactive airway disease, organizing pneumonia, pulmonary fibrosis, pulmonary hypertension, pulmonary emboli, and tracheal disease. The incidence and natural history of these findings is unstudied.

Our study aiming to look in improvement of Pediatric Respiratory Assessment Measure (PRAM) score as a primary outcome. The secondary outcomes involving the need for second step management, need for admission and possible side effects. It's double blinded randomized control study comparing Nebulized Epinephrine with standard treatment (salbutamol + Ipratropium) versus the standard treatment only in pediatric patient. A pilot study will be conducted before to detect the sample size required and data will be collected at deferent interval post treatment targeting intension to treat for analysis.

Acute heart failure is a common reason for emergency department visits and hospitalization, but the diagnosis can be challenging because of non-specific symptoms and signs. The current diagnostic approach to acute heart failure has modest accuracy, leading to delayed diagnosis and treatment, which associate with worse prognosis. Prior work suggests diagnostic accuracy can be improved with the addition of multiple circulating biomarkers discovered through proteomics, and this study will derive and validate a multi-marker model to improve diagnostic accuracy for acute heart failure in the emergency department.

Critically ill patients are exposed to many sources of discomfort and traumatic experiences, especially if they require invasive mechanical ventilation (IMV). Dyspnea, or sensation of "not getting enough air - suffocation" is the most common and distressing symptom experienced by IMV patients, far more unpleasant than pain. But, contrarily to pain, dyspnea has received only little attention and is still markedly under-recognized in IMV patients. Moreover, given the deleterious short- and long-terms consequences of letting IMV patients with dyspnea, its assessment and treatment figures among the main next great cause in critical healthcare. However, dyspnea assessment in IMV patients is a challenge since many of them cannot express their suffering (e.g. sedative drugs, mouth tubes). Dyspnea observation scales (DOS) are promising alternatives that allow to strongly suspecting dyspnea. These scales encompass the dyspnea multidimensionality assessing the respiratory drive (respiratory rate, excessive use neck muscle, nasal flaring), neurovegetative signs (heart rate) and emotions (fearful face). DOS allows calculation of scores strongly correlated with dyspnea in IMV communicative patients and responsive to dyspnea treatment even in noncommunicative ones. However these scales (1) require human resources, (2) still elicit caregivers' subjectivity (fearful face), and (3) are discontinuous, whereas dyspnea is unpredictable, and thus may lead to false appreciation of clinical deterioration. Thus there is an urgent unmet need for technology-enhanced clinical surveillance tools that reliably detect dyspnea in IMV patients and tailor its relief. Infrared thermal imaging (IRTI) offers a unique opportunity to automatically and continuously compute DOS. Indeed, it has been demonstrated as reliable to measure heart and respiratory rate in patients and detect facial expressions even during surgical intervention. The study goal is to prove the concept that IRTI camera device is feasible and reliable to strongly suspect dyspnea, based on the calculation of DOS including heart and respiratory rate, facial expression of fear, and activation of Alae nasi muscle, in IMV patients experiencing an asphyxial threat during a spontaneous breathing trial. The second study goal is to assess the performance of of this multidimensional video taped monitoring to predict the outcome of the spontaneous breathing trial. This project deals with the perspective that artificial intelligence and the development of autonomous patient-machine interfaces will give access to patients' emotions by the analysis of behaviors including facial expressions, in order to improve comfort and reduce traumatic memories of the ICU stay.
