Filter by: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.
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.
When an individual experiences a sudden onset of neurological symptoms, such as one-sided weakness, visual abnormalities, and/or slurred speech, there is concern that they are having a transient ischemic attack/stroke. A stroke is a medical emergency that requires immediate treatment and further evaluation to prevent a future stroke. Unfortunately, when a patient presents to the emergency department or a clinic with transient or mildly observable neurological symptoms, it is difficult to diagnose a stroke and many times, imaging may not reveal a stroke. This poses the risk of discharging patients without appropriate stroke care. This study aims to evaluate the feasibility of administering portable electroencephalogram (EEG) devices to diagnose transient ischemic attack/stroke. An EEG is a device that measures electrical activity in the brain. This study involves comparing EEG data of individuals who present with transient neurological symptoms or have known stroke with EEG data of generally healthy individuals. From this study, the investigators anticipate that it will be feasible to administer portable EEG and that portable EEG can be used to accurately diagnose stroke.
This study ought to identify the occurence of the major adverse cardiovascular events (MACE) and the pumonary emoblism (PE) in patients undergoing elective primary THA & TKA
Support for physical activity is necessary to sustain health and reduce the risk of stroke recurrence after stroke or transient ischemic attack (TIA). Still, rehabilitation services are not available to many of those who potentially would benefit from such services largely due to barriers related to accessibility. While mobile health is a promising strategy to support physical activity, there is a gap in knowledge regarding the implementation of technology that meet the needs of people post stroke or TIA in order to foster adherence and engagement in physical activity. This project therefore seeks to improve health and reduce the risk of recurrent stroke among people post stroke or TIA by increasing the access to physical activity through telehealth. The present project builds on experiences of telehealth-delivered physical activity in Australia where restricted access to health-care services is a longstanding problem. Collaborating researchers in Australia have developed a telehealth program (i-REBOUND- Let's get moving) which has been designed and tested in collaboration with end users, through a series of feasibility and pilot studies. The i-REBOUND program provides support for physical activity through physical exercises supervised by a physiotherapist and behavior change techniques for physical activity (i.e. individual counseling, information, recommendations, goal-setting, self-monitoring and structured follow-ups) across 6 months. The intervention is delivered to people post stroke or TIA in their own homes via video-meeting. This study, which is conducted in Sweden, aims to evaluate if the i-REBOUND program supported by a new mobile application could be delivered as intended through a pilot randomized controlled trial in order to determine the feasibility and preliminary effects in people post stroke or TIA living in urban and rural regions of Sweden.
This is a randomized, controlled, active comparator arm, outcome assessor blind, parallel group design on 90 patient with diagnosis of ischemic stroke admitted in Bou-Ali Sina Hospital, Sari,Iran.The aim of study is assess the efficacy of ticagrelor plus aspirin in reduce of minor non-cardioembolic ischemic stroke or high risk TIA recurrence during first 3 months.
Laparoscopic surgery is an alternative to open surgical techniques for reasons such as less blood loss,less need for transfusion, shorter discharge time. In laparoscopic cases, various positions are given to patients, especially trendelenburg, in order to remove organs and see the area of the operation more easily. The Trendelenburg position causes cerebrovascular changes.Several studies have reported an increase in intracranial pressure (ICP)at the Trendelenburg position. There are also studies that show brain tissue oxygen saturation (SctO2) decreases in this position. Research has reported that cerebral perfusion pressure decreases if the position lasts longer.When pneumoperitonium is administered during laparoscopic surgery, cerebral blood flow may increase as a result of the increase in PaCO2.Brain tissue oxygen saturation depends on blood flow.There is also an inverse ratio between end tidal CO2. To prevent deterioration of cerebral function, methods are needed that determine the onset of desaturation and make early intervention possible. The method,known as near-infrared spectroscopy (NIRS), offers a fixed non-invasive and safe method of determining cerebral desaturation.In addition, NIRS has the potential to improve patient outcomes, reduce postoperative complications and duration of post-anesthesia care.Changes in NIRS measurement values associated with position, especially today, are seen in cerebral perfusion in patients undergoing major surgery, oxygenation and postop have been associated with cognitive dysfunction in the process.Postoperative cognitive dysfunction is associated with increased mortality and therefore it is very important to identify factors that increase risk in order to take appropriate protective measures.Intracerebral ischemia and desaturation may be responsible for the development of POCD. In this study, we aimed to observe NIRS changes due to Trendelenburg position and pneumoperitonium in patients undergoing laparoscopic major abdominal oncological surgery and to examine the effect of POCD on early stage.
Stroke is thought to cause disability immediately after stroke followed by a 3-to-6-month recovery period, after which disability levels are supposed to stabilize unless recurrent events occur. However, studies showed that post-stroke recovery is heterogeneous. While some stroke survivors quickly recover, others may show an accelerated accumulation of disability over time. The current prospective observational study will investigate trajectories of multidimensional functioning and self-rated health in the year after stroke. Particularly, the study aims to explore the relationship between trajectories of disability and self-rated health. Moreover, the study will focus on potential predictors of changes in disability and self-rated health, i.e., views on aging and psychological resilience. Patients will be recruited during their stay at the stroke unit and participate in a face-to-face interview and four follow-up telephone interviews in the post-stroke year.
200 patients presenting with symptoms of acute ischemic stroke or transient ischemic attack were included. All patients free of AF on presentation underwent 48 hours Holter monitoring within one week.
This study is a multi-center, prospective, single-arm, non-significant risk (NSR) device study in which up to 150 evaluable subjects with suspicion of embolic stroke of undetermined source (ESUS) will be evaluated with NB-IS TCD and standard of care TTE to screen for right to left shunt (RLS) or patent foramen ovale (PFO). Additionally, up to 150 evaluable subjects will be evaluated with NB-IS TCD and standard of care TEE.
