Filter by:Ultrasound (US) is widely used as a diagnostic tool in a hospital setting. In a medical department, diagnosis like heart failure or most kinds of heart diseases, hypervolemia, hypovolemia, pleural effusion, pericardial effusion, ascites, diseases in the gall bladder/bile tract, urine tract and venous thrombosis are common. US is the key diagnostic tool in these diagnosis, and on early diagnosis is crucial with respect to the patients well-being and inpatients workflow. 1. The aim is to study the clinical use of pocket-size US as a screening diagnostic tool in an medical department with respect to inpatients workflow and diagnostics. Method: Patients admitted (in certain preset periods) to Department of medicine will be randomized to routinely adding an ultrasound examination with pocket-size device by residents on call. Time to definitive diagnosis, time to definitive treatment and time to discard will be recorded. US findings will be validated against standard echocardiography, or standard US/CT/MRI performed at the Radiological department.
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.
Although drug therapies and pulmonary rehabilitation have greatly improved COPD symptoms, as many as 50% of patients with severe COPD have inadequately controlled dyspnea. Device-guided breathing is a behavioral intervention that guides respiratory rates into a therapeutic range; prolongation of the expiratory phase improves hyperinflation, the most significant driver of dyspnea in this population. Device-guided breathing, has no known side-effects, and may represent a cost effective adjunctive treatment for dyspnea in severe COPD.
The purpose of this study is to evaluate the capacity of some novels biomarkers Procalcitonin (PCT), Midregional Proadrenomedullin (MR pro ADM), Midregional pro-atrial natriuretic peptide (MR pro ANP), Copeptin (CT pro arginine vasopressin), Pro endothelin to stratify the risk in severe dyspnea.
For the patient with acute dyspnea in the ED, early differentiation between CHF and non-CHF causes is essential for proper management. The capacity to triage patients quickly and accurately has a beneficial impact upon outcome, disposition, stratification and length of stay in the ED and required length of hospital admission. The ability to assess pulmonary status rapidly by quantitative regional vibration technology offers significant potential advantage for earlier diagnosis. The VRI technique may provide a quick and accurate method of differentiating between dyspnea due to HF and dyspnea due to pulmonary causes; thereby improving management and outcomes.
Establishing new biochemical markers in the differential diagnostics and risk stratification in heterogeneous patient collectives is becoming more and more important. The markers should be objective, reliable, reproducible, quick and cost effective as well as specific and sensitive. Concerning the differential diagnostics of "dyspnea", NT-pro-BNP plays the most important role for the evaluation of a cardiac origin. However, a corresponding biochemical marker for pulmonary stress is lacking. The aim of the study at hand therefore was the evaluation of surfactant protein B in the differential diagnostics of pulmonary and cardiac diseases.
The purpose of this study is to evaluate a validated diagnostic prediction model in the appropriate diagnosis of Acute Heart Failure (AHF) in patients presenting at the emergency department with undifferentiated dyspnea.
This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine Inhalation Aerosol USP, an HFA-MDI (E004), using a stable isotope deuterium-labeled epinephrine (epinephrine-d3) to differentiate the administered drug from the endogenous epinephrine, in healthy male and female adult volunteers. The current study is designed for a more thorough evaluation of the E004 Pharmacokinetics. Safety of E004 will also be evaluated, under augmented dose conditions.
The feeling of shortness of breath is very common in lung cancer. It is uncomfortable for patients and upsetting for their family. Although drugs like morphine and oxygen can help some patients feel better, they don't help everybody, and they are not used in patients with early symptoms. More relief is needed for these patients. The investigators are studying a drug called tiotropium, which is used in emphysema. It is an inhaler that opens the airways to allow easier breathing. Every patient will get the drug but also a placebo, in a random (flip of a coin) order. They will get each for 2 weeks. The investigators will see if they feel better with the drug.
Breathlessness is a common, distressing symptom in advanced malignant and non malignant disease, and impacts significantly on quality of life. Breathlessness in end stage disease is also responsible for significant healthcare resource usage. Escalante [1] reported hospital admission rates of 60% in patients presenting to a cancer treatment centre with breathlessness. Preliminary trials of breathlessness clinics with selected groups of patients have been promising, but lack data on their cost effectiveness. The principal aim of the research is to develop and evaluate the effectiveness and cost effectiveness of a multidisciplinary outpatient breathlessness support service (BSS) for the palliation of breathlessness, in advanced malignant and non malignant disease. This is a phase II study that aims to test the hypothesis that a BSS will improve patient mastery over breathlessness and reduce the use of healthcare resources (including GP consultations,accident and emergency attendances, and length of hospital stay) compared with usual best medical care alone (UC),at an acceptable level of cost effectiveness.The outcomes of this study will also help to determine sample size,develop and test methods for a phase III trial that will follow on from this project. This study will run over 2 years. Breathless patients with advanced malignant and non malignant disease who have already been optimally medically managed will be eligible. The service will be run in the outpatient department of King's College Hospital, and patients will also be assessed in their own home and by telephone interviews. At baseline we will assess respiratory function and breathlessness mastery and severity using validated scales, and health service usage. Individuals will be randomised to the intervention group [IG] (n=55) or UC (n=55). The IG will attend the new outpatient clinical service with multiprofessional input. Assessments will be repeated at 4, 10 & 24 weeks. 1.Escalante, C.P., Martin, C.G., Elting, L.S. et al., Dyspnea in cancer patients.
