Filter by:The proposed research study will be a prospective observational study designed to validate the Canadian Triage Assessment Scale (CTAS) in regard to work of breathing in patients in the emergency department. The investigators will assess inter-rater agreement between nurses & emergency physicians for assessment of work of breathing.
Aim of investigators was to study whether abnormalities of lung diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO) in long COVID may have a clinical impact in relation to exercise intolerance.
The randomized controlled trial will be conducted to evaluate the effectiveness of a Multi-domain Tai Chi Digital Therapy for treating the individuals suffering from the long term COVID-19 syndrome (Long COVID).
The BREATHE-easy is a randomized control trial assessing the efficacy of the novel PneumoCool device to alleviate subjective shortness of breath. The PneumoCool device is a disposable, bladeless, highly portable device that uses medical-grade air that confers many advantages in a hospital setting.
Different studies have suggested that COPD is associated with elevated alveolar NO and increased expression of NOS2 in alveolar walls, small airway epithelium and vascular smooth muscle. Furthermore, arginase activity in COPD is shown to correlate inversely with total NO metabolite in sputum and with pre- and post- bronchodilator FEV1; at the same time ADMA levels in serum is shown to be correlated with airway resistance and ADMA in COPD airways was documented to be able to shift the L-arginine metabolism towards the arginase pathway. As demonstrated in a guinea pig model, the arginase inhibition can shift the L-ornitine: L-citrulline ratio towards L-citrulline, preventing neutrophilia, mucus hypersecretion and collagen synthesis. Thus, increasing substrate availability for NOS by arginase inhibition or supplementation of L-arginine or L-citrulline or a combination thereof, may represent a window of opportunity in patients with COPD. The present study was constructed in order to investigate as a primary objective whether in symptomatic patients with COPD, daily bioarginine on top of chronic inhaled therapy can improve patients' respiratory symptoms and dyspnea during daily life activities. The secondary objective of the study is to determine whether there is any correlation between improvement in respiratory symptoms and distance walked at the 6MWT and lung function parameters. In order to do so, the investigators designed a multi center, interventional, prospective, randomized, controlled vs placebo, proof of concept study: COPD patients will be randomized to receive BioArginine twice daily on top of chronic inhaled therapy or to continue their chronic Inhaled therapy plus placebo for 6 weeks. In order to evaluate the impact on respiratory symptoms and dyspnea the CRQ (Chronic Respiratory disease Questionnaire) and the LCADL (London Chest Activities of daily Living) Scale, as well as the 6MWT, will be used.
Retrospective observational study performed in a internal medicine ward of a French university hospital. Included patients were hospitalized for acute shortness of breath who have benefited from a eFOCUS which was defined as a focused cardiac Ultrasound with utilization of Doppler measurements. The objectives were the therapeutic and diagnosis changes induced by eFoCUS. The primary endpoint was defined by the pooled introduction or discontinuation of diuretics, antibiotics or anticoagulants associated with eFoCUS results.
Most people who have coronavirus disease (COVID-19) recover completely without any sequelae. However, some patients continue to experience symptoms of COVID-19 even though their tests turn negative. This clinical spectrum that occurs after acute infection is called the post-COVID syndrome (PCS). Dyspnea, pain, decreased exercise capacity, limitations in activities of daily living, poor sleep quality, anxiety and depression are common symptoms in PCS. The aim of our study is to examine the effect of tele-rehabilitation-based exercise program on dyspnea, pain, functional capacity, sleep quality, anxiety and depression in individuals with PCS.
To identify pulmonary vascular disease in post/long-COVID-19 patients as a cause of dyspnea/exercise limitation and to differentiate it from other causes of dyspnea
Acute Heart failure (AHF) is a common cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This association is frequently underestimated with regard to the difficulty of clinical diagnosis. The investigators expect that the application of the lung ultrasound could be useful in this issue.
This study aimed to analyze and investigate whether the use of the PMcardio clinical assistant leads to a more efficient patient management in primary care and more accessible specialised care compared to usual standards of care and to assess the reliability and safety of the PMcardio smartphone application in the primary care use environment. Additionally, to evaluate time savings and cost saving implications of increased availability of specialised care at the primary care level.
