Filter by:This proof of concept study aims to evaluate the effects of applying ketone bodies to human atrial tissue biopsies using an atrial strips model and high resolution respirometry.
Patients who have suffered a stroke are having an increased risk of having recurrent stroke in the future. This risk of stroke is increased by atrial fibrillation, which often "comes and goes" (called paroxysmal) and hence escapes routine diagnostics. The hypothesis of Find-AF 2 is that enhanced (evaluation in a ECG core lab), prolonged (at least 7 days of rhythm monitoring annually) and intensified (continuous rhythm monitoring in high risk patients) not only finds atrial fibrillation more often, but that changes in therapeutic management (e. g. start of anticoagulation after detection of atrial fibrillation) results in a decrease of cardioembolism (which can be either recurrent stroke or systemic embolism). To prove this hypothesis, patients will be randomised into two groups: the first group will receive the currently available standard care for patients with stroke. In the second group, cardiac rhythm monitoring adapted to the risk of the occurrence of atrial fibrillation is performed - either with a 7-day long-term ECG (at baseline, after 3 and 12 months and every 12 months thereafter) or with continuous monitoring using an implantable cardiac monitor. If atrial fibrillation is detected, this information will be given to the treating study physician. Any therapeutic decision is at the discretion of the treating physician, but should follow current guidelines.
An open-label, prospective, observational, multicenter study. The study enrolls adult outpatients with CCI from 8 federal districts of the Russian Federation.
Retrospective analysis of transcutanesou oximetry (Tcpo2) recording for patients referred with suspected critical limb ischemia searching for specific changes in TcpO2 patterns.
This study was designed to compare excimer laser combined with drug-coated baloons with angioplasty alone in the treatment of infrapopliteal lesions in patients with critical limb ischemia.
Perinatal asphyxia is a major cause of hypoxic Ischemic encephalopathy (HIE), perinatal death and long term neurodisability. This can be devastating for the individual and their family; the healthcare and litigation costs notwithstanding. In recent years have attempted to quantify the effect, and wider impact of intrapartum compromise, as well as the underlying mechanisms for it. After a poor outcome related to intrapartum care parents and healthcare practitioners often strive to understand whether the event could have been predicted and/or prevented. This can be difficult to answer, at least partly related to the heterogeneous fetal response to perinatal asphyxia. Mothers and the maternity service are increasingly encouraged to personalize care and their choices around the birth process, however the information required to guide these choices is most often missing. This makes it difficult for women and professionals to make an informed choice about their care, including the safest mode of birth for them and their baby. Aim of the study: Identifying antenatal and intrapartum risk factors associated with neonatal hypoxic ischemic encephalopathy.
To investigate which findings on a non-specific CT scan that predict acute primary intestinal ischaemia.
Background: Acute ischemic cardiovascular and cerebrovascular diseases are a kind of diseases with high incidence, rapid progression, poor prognosis and high mortality and disability rate of the circulatory system, mainly including acute myocardial infarction, acute ischemic stroke and acute limb ischemia, which place a heavy burden on individuals, families and society due to their severe prognosis and high medical costs. At present, the diagnosis and treatment of ischemic cardiovascular and cerebrovascular diseases mainly focus on single organ diagnosis and treatment of target organs, lacking of indicators to comprehensively evaluate the body's pathophysiology. As ischemic disease of the circulatory system, ischemic cardiovascular and cerebrovascular diseases have common pathophysiological basis such as ischemia, hypoxia and inflammation. These common pathophysiological basis suggests that different acute ischemic cardiovascular and cerebrovascular diseases can be monitored and evaluated from an integrated perspective, it suggests the possibility of comprehensive diagnosis, evaluation and treatment guidance. At present, the "circulatory integration" therapy represented by the combined treatment of heart and brain has achieved certain results, but there is no corresponding evaluation system to provide accurate guidance. Therefore, with the concept of "circulation integration", it is an urgent problem to find the common indicators of the circulation system and construct the hierarchical diagnosis and subsequent evaluation system of acute cardiovascular and cerebrovascular integration. The development of efficient and comprehensive stratified diagnosis and prognosis evaluation system is of great significance in clinical, market and social aspects. At the early stage of the efforts our team, it was found that Dan Shen Su-(±)-3, 4-dihydroxyphenylacetic acid (DSS) could be detected in the plasma and urine of patients with acute myocardial infarction and ischemic stroke through metabolomics. It has been proved that it can be generated by the transformation of dihydroxyphenylalanine by proteus mirabilis, and its structure is consistent with the water-soluble component of salvia miltiorrhiza, which is related to the body's states of ischemia, hypoxia and inflammation. The findings provide a material basis for the "circulatory integration" assessment of acute ischemic cardiovascular and cerebrovascular diseases. Objectives: This study aims at acute ischemic cardiovascular and cerebrovascular diseases, with the concept of "circulatory integration", to build a hierarchical diagnosis and prognosis evaluation system with DSS as the core, in order to improve the diagnosis rate and cure rate, improve the prognosis and reduce mortality of ischemic cardiovascular diseases. Methods: The project included 500 patients with acute myocardial infarction, 300 patients with acute ischemic stroke, 300 patients with acute lower limb ischemia, and 200 healthy controls in the Affiliated Hospital of Xi'an Jiaotong University, Xi'an, Shaanxi, Peoples R China. Plasma and urine were collected during the disease process. Various relevant clinical indicators including DSS level were included, COX model was applied to analyze the influence of multiple factors on the prognosis of the above diseases, and the indicators were screened and the integrated stratified diagnosis and prognosis evaluation system of acute ischemic cardio-cerebrovascular system with DSS as the core were established. The newly established integrated stratified diagnosis and prognosis assessment system was used to evaluate 200 patients with each of the three diseases, and the sensitivity and specificity of the new assessment system were tested. And a simple, rapid and accurate method for detecting DSS was developed.
The hypothesis of this study is to determine if there is a benefit afforded by the use of systemic Sildenafil to patients with choroidal and retinal degenerations and dystrophies, such as vitelliform degeneration, dry and reticular age-related macular degeneration (AMD) as well as patients with hereditary and acquired retinal dystrophies such as retinitis pigmentosa and central serous retinopathy.
A pilot trial for assessing early microvascular alterations after aneurysmal subarachnoid hemorrhage using dynamic 18F-FDG PET/CT. The primary endpoint will be the measure of early changes in cerebral glucose uptake reflecting microperfusion.
