Filter by:The goal of this clinical trial (pilot study) is to learn about the microcirculatory regulation of the lower extremity under orthostatic stress with and without RIC - Remote Ischemic Preconditioning in healthy participants. The main question it aims to answer are: Do the beneficial effects of RIC withstand orthostatic stress? / Does RIC benefit lower extremity microcirculation in ortho-statically stressed subjects? Is there a relationship/correlation between the variables of microcirculation and hemodynamics in the context of RIC and orthostatic loading?
Shock is a frequent, etiologically heterogeneous and often lethal clinical condition of intensive care medicine. This is particularly true for very old intensive care patients (VIPs), who are among the fastest-growing subgroups of all intensive care unit (ICU) patients and who suffer from a significantly impaired outcome. In addition to the treatment of the causes of shock, current therapeutic approaches focus on the stabilization of vital parameters, which in general all reflect macrocirculatory measured values such as blood pressure. In contrast, a disturbance of the microcirculation (blood circulation of the smaller blood vessels <100 µm) is only poorly measurable and delayed. The last generation of AVA-Software (MicroVisionMedical) will calculate different parameters about the capillary densitiv and perfusion in a user-independent way. VIPPER investigates whether a non-invasive measurement of microcirculation using the sublingual mucosa in very old intensive care patients in shock leads to faster recognition and specific treatment of organ dysfunctions. Secondly, this study checks whether this measurement predicts outcome.
The aim of this study is to investigate the effect of a 6-months program of Adapted Physical Activity (APA) on lifestyle, physical activity levels, insulin resistance and adipokines, oxidative stress, microcirculatory haemodynamics and serum levels of specific circulating miRNA in post-menopausal, physically inactive breast cancer patients in oncologic follow-up with or without hormone therapy that had completed adjuvant treatment (radiotherapy and/or chemotherapy) . Furthermore, the study will determine the impact of APA on functional capabilities, on self-reported physical activity, quality of life and psychic health.
The aim of the study is to compare the diagnostic value of this non-invasive vascular imaging tool with the established vascular diagnostic methods for PAD in order to get prognostic data. A higher sensitivity of Fluorescence angiography in order to recognize progression of critical limb ischemia could lead to earlier therapeutic interventions and thereby increase limb salvage. A diagnostic gap would be closed.
In this study we hypothesize that blocking the angiotensin II AT1-receptor improves the insulin-induced microvascular dilatation. Objectives: 1. Does blockade of the angiotensin II AT1-receptor improve the insulin-induced microvascular effects in hypertensive patients. 2. Does blockade of the angiotensin II AT1-receptor impair the insulin-induced microvascular effects in normotensive control subjects?
