Active clinical trials for "Stroke"

Stroke can be defined as an abrupt loss of brain function that is caused by decreased cerebral blood flow. Stroke can occur at all stages of life, but presentation is variable depending on age, involved artery, and underlying risk factors.

Preclinical research has established a convincing connection between changes in the gut microbiota composition and stroke outcome. However clinical data on the gut-brain axis, and its chronic characteristics, is sparse. Additional investigations in the context of ischemic stroke regarding the relationship between dysbiosis and functional changes of the microbiome, as characterized by the metabolome, are still required. The StrokeMicroBiomics study will offer insight into these mechanisms and offer new potential targets for therapeutic interventions. The primary objective is the characterisation of gut dysbiosis in ischemic stroke patients in the acute phase after stroke and during a 3 month follow-up period. The secondary objectives include the identification of dysregulated gut microbiome metabolites and key immune cell populations in addition to the clinical progression of the study participants during the 3 month follow-up period after disease onset.

Prior to discharge from hospital and return home, patients managed for ischemic stroke will receive a pharmaceutical interview to discuss their discharge prescription (indication, method of administration, precautions, and possible side effects). Improvements in the use of medications in the community and in hospital follow-up. Telephone interviews or teleconsultations will make it possible to assess the patient's knowledge of his or her treatment and to re-explain it if necessary to improve patient compliance with treatment.

As with other real=world connected systems, studying the network structure of multiple interactions in the brain (holism versus reductionism) has profound implications in the comprehension of emergent complex phenomena like, for example, the capability to functionally reorganize after cerebrovascular "attacks" or stroke. This dynamic skill, which is known in neuroscience as brain plasticity, is not only interesting from a network perspective, but it also plays a crucial role in determining the motor/cognitive recovery of patients who survive a stroke. Network analysis of functional connectivity (FC) patterns estimated from neuroimaging techniques such as electroencephalography (EEG), magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) has allowed a major breakthrough in the understanding of physiopathology of stroke from a system perspective. Recent evidence from cross=sectional studies1,2 highlights that stroke lesions generally induce i) critical deviation from optimal (i.e. small=world) network topologies supporting both segregated and integrated information processing, ii) altered inter=hemispheric connectivity and modularity, iii) and abnormal region centrality in the ipsilesional hemisphere as well as in the contralesional hemisphere. While these findings provide new descriptors on how stroke lesions affect the functional brain network organization and how this correlates with the resulting behavioral impairment (e.g. hemiplegia, aphasia), they only represent a static picture of the brain plasticity, which is instead intrinsically dynamic, and partially inform on the chances of single patients to recover their motor/cognitive functions. These aspects dramatically limit the investigator's ability to fully understand the brain organizational mechanisms after stroke and to probe the predictive power of possible network=based neuromarkers of recovery. The ATTACK project aims to overcome these technological and methodological barriers by implementing the following three=fold strategy: acquiring a longitudinal dataset of brain and behavioral data in stroke patients and healthy controls, developing new analytic tools to characterize and generate temporally dynamic brain networks, building network=based models of functional recovery after stroke, accounting for individual patients.

To evaluate the effects of mechanical left atrial appendage (LAA) closure for secondary prevention of stroke in the patients with nonvalvular atrial fibrillation

The purpose of this study is to investigate the usability of a new upper limb robot assisted therapy device in stroke patients.

In this study, the researchers will investigate whether the E-effect is present in stroke subjects both on the subjective visual and postural vertical test. In addition, researchers will investigate the impact of the loss of different sensory information sources on the sensory reweighting strategies and perception of verticality by measuring the effect of somatosensory loss on the E-effect.

Experimental research design with two-group repeated-measure design. Experimental group was pressing the Hegu (LI 4), Zusanli (ST 36) , Tianshu(ST 25) and abdominal massage for eight minutes total, press once in the morning and afternoon, seven days total and two days for follow the trail. Control group was pressing sham ponits. Research tools to self semi-structured questionnaire collected data on patient's diet, activity, medication, defecation patterns, subjective defecation feelingauscultation bowel sounds like.

The study investigates the effect of plasma myeloperoxidase (MPO) concentrations on HDL dysfunction during the acute stage of ischemic and haemorrhagic strokes.

The purpose of this study is to determine whether levels of circulating endothelial progenitor cells (cEPC) are increased in the acute phase of ischemic stroke.
