Active clinical trials for "Edema"

Dual-Energy/Multi-Energy/Spectral-CT can visualize bone marrow edema associated with fractures, however, current scientific evidence is mostly derived from to retrospective analyses. Our prospective study systematically analyzes the diagnostic accuracy of the visualization of bone marrow edema by including patients who are scheduled for a CT scan to exclude or further characterize a fracture. After giving informed consent, the CT scan will be performed using a dose-neutral Dual-Energy-/Multi-Energy-/Spectral-CT acquisition technique. If the patient undergoes MRI of the same region within 7 days, this scan will be used as a gold-standard for bone marrow edema. This will allow the quantification of diagnostic accuracy.

This study aims to evaluate the influence and prognostic value of systemic factors (such as the cardiovascular and metabolic status) on the treatment response to anti-VEGF therapy in macular edema due to diabetes or retinal vein occlusion.

An increasing number of clinical studies on SD-OCT of ocular pathologies and potential new clinical applications has recently been published in the peer-reviewed literature. However, the successful use of SD-OCT in routine clinical use depends upon the diagnostic sensitivity, biometric accuracy and reliability of the SD-OCT machines. This prospective, comparative, observational study aims to evaluate the imaging quality and diagnostic performance of two commercially available SD-OCT machines for both the anterior and posterior segment of the eye.

The purpose of this study is to define the current treatment of patients ospitalized with acute cardiogenic pulmonary edema. Clinical and laboratory data collected in the Emergency Department will used to investigate the primary outcome (mortality) and risk factors related to the primary outcome.

To use machine learning for early detection of malignant brain edema in patients with MCA ischemia

The purpose of this study is explore if a partnership and screening program put in place between a busy retina practice and their referring diabetes care offices can improve diabetic retinopathy and diabetic macular edema diagnosis, care and overall diabetes control in patients with diabetic eye disease.

We use a new technology (Nexfin from BMEYE-Inventive Hemodynamics) to monitor Cardiac Output, Blood Pressure, Fluid Responsiveness, Pulse Oximetry, Hemoglobin Concentration, Oxygen Delivery in Climbers during their process of acclimatization on a expedition to Mount Aconcagua.

This study aims to evaluate brain injuries and brain edema with non-contact DCS-Speckle multi-parameter imager.

Primary objective of our study is the development and validation of an application for smart-TVs for the self-examination of the distant visual acuity of patients diagnosed with macular edema.

Pulmonary edema can be classified into "cardiogenic pulmonary edema" and "non-cardiogenic pulmonary edema" according to the underlying etiology. Cardiogenic pulmonary edema is caused by the dysfunction in the cardiac pumping capability, leading to the transudation accumulation in the pulmonary peri-capillary space. The predisposing factors of non-cardiogenic pulmonary edema are numerous, including severe infection, renal failure, auto-immun reaction, etc. The mortality rate of pulmonary edema is relatively high, especially the non-cardiogenic one. To distinguish the type of pulmonary edema at the early stage is important for its treatment. Lung sound analysis via stethoscope is a simple diagnostic method to lung diseases clinically. Among many kinds of lung sounds, the "crackle" and "rale" are frequently found in pulmonary edema. "Rale" is also called "moist rale". It is considered as low-frequency wheezes and is often seen in cardiogenic pulmonary edema. On the other hand, "crackle" is also called "dry rale", which is a kind of high-frequency wheezes and usually seen in Acute Respiratory Distress Syndrome (ARDS) that is classified into non-cardiogenic pulmonary edema. This proposed project intends to establish a digital diagnostic method for pulmonary edema. The lung sound of patient with pulmonary edema will be collected by the lung sound acquisition system. By identifying the significant spectrum characteristics of cardiogenic pulmonary edema and non-cardiogenic pulmonary edema, the diagnostic system might be established.
