Active clinical trials for "Stroke"

Objective: To study the efficacy and safety of apixaban as stroke prophylaxis in patients with chronic kidney disease (CKD) stage 5 and atrial fibrillation (AF) with or without dialysis treatment. The study hypothesis is that compared to no anticoagulation, apixaban reduces the incidence of ischemic stroke without causing an unacceptable increase in fatal or intracranial bleeding events. The secondary objectives are to evaluate the risk of all-cause mortality, cardiovascular events, and major bleeding in people with CKD stage 5 and AF treated with apixaban compared to standard of care without anticoagulation. Trial design: Pragmatic Prospective Open Label Randomized Controlled Clinical Trial, phase 3b over 12-72 months. Trial population: 1000-1400 patients at ≈50 sites in Sweden, Finland, Norway, Iceland and Poland Eligibility criteria: Adults ≥18 years with CKD stage 5 (ongoing treatment with any chronic dialysis treatment OR an estimated glomerular filtration rate (eGFR)* <20 ml/min/1.73 m2 at least twice 3 months apart of which at least one occasion is <15 ml/min/1.73 m2 due to CKD during the last 12 months) and a diagnosis of chronic, paroxysmal, persistent, or permanent AF or atrial flutter (AFL) with CHA2DS2-VASc score ≥2 for men or ≥3 or more for women as an indication for oral anticoagulation. The exclusion criteria are AF or AFL due to reversible causes, rheumatic mitral stenosis or moderate-to-severe non-rheumatic mitral stenosis at the time of inclusion into the study, a condition other than AF or AFL that requires chronic anticoagulation, contraindications for anticoagulation, active bleeding or serious bleeding within 3 months, planned for surgery within 3 months, and current use of strong inhibitors of both CYP3A4 and P-glycoprotein. Interventions: Randomization 1:1 to treatment with apixaban 2.5 mg twice daily and standard of care, or standard of care and no anticoagulation. Outcome measures: primary efficacy (time to first ischemic stroke); primary safety (the composite of time to first intracranial bleeding or fatal bleeding); secondary efficacy (time to all-cause mortality, time to cardiovascular event or cardiovascular death); secondary safety (time to first major bleeding according to International Society on Thrombosis and Hemostasis (ISTH) criteria)

Consequences of stroke are manyfold but all of them are important factors on the long-term outcomes of rehabilitation, becoming an important health problem with requires health strategies with advanced age. High intensity interval training (HIIT) is an efficient training protocol used in cardiac rehabilitation programs, but owing to the inter-individual variability in physiological responses to training associated to cardiovascular diseases, the exercise dose received by each patient should be closely controlled and individualized to ensure the safety and efficiency of the exercise program. The heart rate variability (HRV) is actually being used for this purpose, as it is closely linked to de parasympathetic nervous system activation. In this way, higher scores in HRV are associated with a good cardiovascular adaptation. The objective of this protocol is to determine the effect of HIIT compared with HRV-guided training on cardiorespiratory fitness, heart rate variability, functional parameters, body composition, quality of life, inflammatory markers, cognitive function, and feasibility, safety and adherence in patients after stroke undertaking an 8-week cardiac rehabilitation program. This will be a cluster-randomized controlled protocol in which patients after stroke will be assigned to an HRV-based training group (HRV-G) or a HIIT-based training group (HIIT-G). HIIT-G will train according to a predefined training program. HRV-G training will depend on the patients' daily HRV. The peak oxygen uptake (VO2peak), endothelial and work parameters, the heart rate variability, the functional parameters, the relative weight and body fat distribution, the quality of life, the inflammatory markers, the cognitive function, and the exercise adherence, feasibility and safety will be considered as the outcomes. It is expected that this HRV-guided training protocol will improve functional performance in the patients after stroke, being more safe, feasible and generating more adherence than HIIT, providing a better strategy to optimize the cardiac rehabilitation interventions.

In this study, it is aimed to examine the effect of rigid taping on hyperextension control in stroke patients with knee hyperextension in the stance phase of gait. Hypothesis Ho: Rigid taping has no effect on the control of knee hyperextension in stroke patients. H1: Rigid taping has an effect on the control of knee hyperextension in stroke patients.

The goal of this clinical trial is to assess the safety and feasibility of providing extra doses of rehabilitation therapy for persons with a recent stroke. The therapy treatment targets to improve arm function by introducing telerehabilitation to the bedside of participants during the inpatient rehab admission period. Participants will use a newly developed functional training system (HandyMotion) to access therapy treatment program directly from their hospital room. HandyMotion is a sensor-based training system that can connect to the TV set in the hospital room, enabling patients to access their therapy training program to practice rehab-oriented games and exercises ad libitum, at any time of the day.

Background: The TNKCAT trial represents an innovative approach to optimize timely reperfusion in the Mothership and Drip-and-Ship scenarios. The logistic advantage of a single bolus infusion of TNK (compared to 1-h infusion of tPA) would markedly reduce the needle-to-groin and Door-in- door-out time. The implementation of a quality improvement package (QIP) in the TNKCAT trial would directly improve the quality and efficiency of the Health Care System. In addition, an improvement of transfer models would reduce the cost of unnecessary transfers, together with the fact that TNK is up to 50% less expensive than tPA, makes the TNKCAT in firm line with the sustainability strategy of the National Health Care system. Outcomes: The aim of the present study is to determine the safety and efficacy of TNK (0.25mh/kg) compared to tPA (0.9 mg/kg) in patients with Large Vessel Occlusion (LVO) suspicion, candidates for thrombectomy, in both Mothership and Drip-and-Ship scenarios. Study Duration: 2 years. Patients will participate in the trial for 3 months. Study design: Multicentre, prospective, randomized open-label blinded endpoint (PROBE) phase III study in acute stroke patients with LVO suspicion within 4.5 hours of stroke onset, candidates for EVT. Patients will be randomized 1:1 to standard dose tPA (0.9 mg/kg) or TNK (0.25mg/kg) before EVT. Clinical, imaging and outcome data will be collected at baseline, 24-36 hours, day 3, day 5 and day 90. Estimated enrollment: 500 patients

This study focuses on the effects of Action Observation therapy on stair walking, balance and self-efficacy in chronic stroke patients. This study will be conducted in Helping Hands Institute of Rehabilitation Sciences and Shifa Surgical Hospital Mansehra. It is a Randomized Control Trial. Non probability convenient sampling technique will be used to assess a total number of 40 respondents. Questionnaires and consent forms will be filled by the respondents. Each patient will be screened by using a simple selection Performa relevant to inclusion and exclusion criteria. Total 30 patients will be included in the study and then divided into two groups i.e. Action observation therapy and Convention Therapy group with 15 individuals in each. Each group will be assessed thrice i.e. pre, post and follow up surveys. Each of them will receive the convention therapy for 30 mins except for the Action Observation therapy (AOT) group, which will also receive the additional 30 minutes session of action observational training. Total 18 sessions, 3 days a week for a total of six weeks will be performed on each patient. Fugel Meyer Assessment Scale for lower limb, Timed Up and Go test, Timed Stair Test, Step test and self-efficacy scale will be used for the assessment. Baseline assessments of both group will be done on 1st week before the application of protocol, second assessment will be done on 4th week and then final assessment will be done on 6th week of the protocol.

Stroke is the main cause of disability and the second main cause of dementia. Approximately 21.5% of patients develop dementia within 4 years after stroke. The main clinical manifestation of dementia is memory and cognitive impairment. At present, acetylcholinesterase inhibitors and NMDA glutamate receptor antagonists, were used for dementia treatment, but those drugs have limited efficacy. Exosome is an extracellular vesicle from the endosomal, size range from ~40 to 160 nm (average ~100 nm). It contains many cells including DNA, RNA, fat, and metabolites, as well as cytoplasm and cell surface proteins that play a role in regulating intercellular communication. Some studies believe that exosomes in the circulation are an ideal marker to reflect the pathological progress and recovery of stroke, and play a key role in the reorganization of tissues and the progress of neurodegeneration after stroke. Our previous studies have known that acupuncture can increase the long-term potentiation of hippocampal CA1 in rats with ischemic stroke, and improve learning-memory and neurological function. Therefore, the purpose of this study is to explore the role of acupuncture-induced exosome in the treatment of post-stroke dementia.

Acute ischemic stroke (AIS) patients with basilar artery occlusion (BAO) present a devastating, life-threatening prognosis. Urgent recanalization with endovascular mechanical thrombectomy is routinely performed in patients with BAO although the level of evidence is lower than that in anterior circulation occlusions (randomization in this population versus medical treatment alone having been impossible in recent studies). Recently, a large retrospective study supports the interest of thrombectomy in this population . Speed and grade of the recanalisation have a major impact on clinical outcome. Favorable outcome at 90 days is strongly associated with the successful recanalization status at the end of the endovascular procedure (OR=4.57, 95%CI=1.24-16.87, P=0.023). First pass effect has been shown to be a strong marker of efficacy of endovascular procedure with significant correlation with clinical outcome. Thrombectomy with Stent retrievers dramatically changed the prognosis of anterior circulation large vessel occlusion strokes and currently used in BAO patients (posterior circulation). Contact aspiration (CA) is currently used in anterior large vessel occlusions (COMPASS trial, Lancet 2019), with similar rates of recanalization and favorable outcomes (Boulanger M, 2019), as well as in BAO patients . However, the benefit of CA compared to SR for the treatment of BAO remains under debate with the superiority of first line CA compared to SR or no difference. Available data are based on retrospective studies with no data from RCT. In this context, a randomized controlled trial is needed to assess the benefit of CA versus SR.

The purpose of this study is to compare the efficacy of conventional therapy with a framework intervention for upper limb motor rehabilitation based on the promotion of self-efficacy and social participation/interaction through a multi-user touch surface

After acquired brain injury (ABI), persons can experience emotional and behavioral difficulties, that can be painful both for the person and his/her family. This clinical study aims at measuring the effectiveness of a third wave cognitive behavioral therapy called "dialectical behavior therapy" (DBT). DBT aims at teaching persons emotion regulation skills, interpersonal effectiveness skills, mindfulness and distress tolerance skills through group and individual sessions. The study's hypothesis is that DBT, in an adapted format for persons with ABI can lead to a better quality of life, emotional and behavioral regulation, and self-esteem decrease in problematic behaviors progress in life goals increase post traumatic growth and spirituality better family functioning and lesser burden for care givers experiencing more emotions and more free will 45 persons with an ABI sustained more than 18 month back, will follow a 3 phases, follow-up with care as usual for 5 months, followed by 5 months of DBT, followed by 5 months of care as usual + DBT monthly sessions. Self- and family-questionnaire will explore quality of life, emotional regulation, self-esteem, stress, anxiety, cognitive difficulties, family functioning and coping, post traumatic growth and spirituality and will be compared across the 3 phases. Results will be analyzed at a group level but also at an individual level (each patient separately) to test for decrease in unwanted behaviors and at a dyadic level (the person and his/her spouse) to test for the mutual effect of regulating emotions. Persons' memories will by analyzed at 3 time points by a linguistic analysis, and experience of free will after ABI will be analyzed by transcribed narratives of participants.
