Filter by:The goal of this observational study is to learn about quality of life, stress and caregiver burden in patients with stroke and their caregivers. The main question is: • to discover the factors associated with quality of life and stress in patient-caregiver dyads. Participants will be asked to fill out questionnaires and agree to provide a hair sample (in order to measure stress hormones in hair) and consent to use of their routine clinical and laboratory data. Researchers will compare a group of participants without stroke to establish a comparable baseline.
The CLIMATE-II Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific health behavior, somatosensory amplification, risk and benefit perception, self-efficacy, health literacy, degree of urbanisation of the patients' administration district and characteristics of the patients' neighborhood are associated with these effects.
In order to determine the abnormal cerebral metabolism in the pathological state, we compared the blood of internal jugular vein, superior vena cava and radial artery during central venous catheterization. Metabonomics, proteomics and inflammatory factor microarray were used to detect the material differences in arteriovenous blood of patients with disorders of consciousness. At the same time, we concurrently compared it with the peripheral plasma metabolome of two additional patient cohorts: those in-stent restenosis and non-restenosis.
The ENIGMA study is a single-centre prospective clinical observational study with the aim to investigate vascular contributions to cognitive decline and dementia. By studying MRI-defined capillary dysfunction and EV profiles, the ENIGMA study links novel imaging and basic research techniques to a clinical cohort of stroke patients. With this study we hope to enhance the understanding of the mechanisms behind post-stroke cognitive decline and dementia.
Atrial fibrillation (AF) is the cause of 20% of strokes, and the risk of stroke in a person suffering from this arrhythmia increases by 5 times. Ischemic stroke in patients with AF is often fatal and, compared with stroke of other etiology, leads to the most pronounced disability and more often recurs. Accordingly, the risk of death in patients with AF-related stroke is 2 times higher, and treatment costs increase 1.5 times. The main interventional method of treating AF, available in most medical institutions, is the use of radio frequency and/or cryoenergy to eliminate destructive damage to the left atrium (LA). The aim of this study is to compare two different interventional methods and identify predictors of recurrence in patients with persistent and long-term AF.
Motivational interviewing (MI) is a style of communication designed to elicit a person's own reasons for change to drive commitment toward a goal. The goal of this study is to assess the effect of trainee-led MI on patients diagnosed with acute stroke or TIA attributable to modifiable risk factors in comparison to conventional post-stroke counseling, based on patient outcomes, and meaning of work and sense of fulfillment for trainees.
A transient ischemic attack (TIA) is a momentary neurological dysfunction due to a brief cessation of blood flow to a region of the brain, resulting in typical signs of stroke (hemiplegia, aphasia, dysarthria), but whose clinical symptoms typically last less than an hour, with no visible lesion on imaging. This diagnosis remains difficult and is essentially based on the clinical judgment of the physician. Because a TIA can be a "pre-alarm" for stroke in 20-30% of cases, it needs to be treated appropriately and as early as possible in the emergency department. Stroke rates after untreated TIA are 5% within 48 hours, 10% within one month and 20% within one year. This risk is calculated using the ABCD² score which is based on the patient's risk factors and the clinical manifestations of TIA. Patients with a score ≥ 3 should be hospitalized as soon as possible for a complete medical evaluation. However, this score has not been scientifically validated, and several specialists agree that all TIAs should be evaluated immediately. Preventing stroke is a major public health issue because it is a serious, disabling and sometimes fatal disease. Given the seriousness of the progression from TIA to stroke, the French National Authority for Health has issued a series of management recommendations. However, in practice, these guidelines remain complicated to follow and patients management may vary and be more or less effective. Therefore, the aim of this study is to highlight the differences in how inpatients and outpatients are managed. Following these observations, solutions will be sought to make the care and management of these patients more efficient and more in line with recommendations.
The Primary Objective is to determine if a new nuclear tracer (named 18F-Florbetaben) used with nuclear imaging (PET imaging) can detect inflamed plaque in patients with recent ACS or stroke/TIA.
In our research, we aim to increase awareness on this issue by classifying the frequency of carotid webs and their radiological classification; Evaluating the clinical data and vascular risk factors of carotid web cases and determining their relationship with ischemic stroke and determining the measures that can be taken for future optimal treatment. We aimed to contribute to their approach.
Scientific Background: In secondary prevention of ischemic stroke, detection of atrial fibrillation (AFib) and subsequent anticoagulation therapy reduce the risk of recurrent stroke by approximately 60%. Prolonged electrocardiogram (ECG) monitoring up to 6 months significantly increases detection of AFib in cryptogenic stroke. Wearables like smartwatches have recently been shown to adequately detect AFib in the general population. Thus, prolonged ECG monitoring after cryptogenic ischemic stroke or transient ischemic attack (TIA) using a smartwatch could lead to a reduction of recurrent stroke by prompting adequate anticoagulation therapy and may constitute a cost-effective, non-invasive, and broadly-available alternative to the current standard of care. Hypothesis: The investigators hypothesize that AFib detection via smartwatch in patients with cryptogenic TIA or ischemic stroke is accurate compared to an implantable event recorder. Methods: The investigators introduce a prospective, intraindividual-controlled, multicentre clinical study in patients with cryptogenic ischemic stroke or TIA. In addition to an implanted event recorder as indicated by clinical standard, included patients receive a smartwatch for detection of AFib. ECG-data from smartwatches will be continuously monitored by two independent cardiologists. As soon as AFib is confirmed, a doctoral appointment is set to evaluate start of anticoagulation. The follow-up period will be six months. The study consists of four study visits: a baseline visit, two phone visits at one and three months, and an end of trial visit at six months. Primary Objective: To compare smartwatch and event recorder based analysis for sensitivity and specificity of AFib detection per patient after six months
