Disorders of consciousness (DOC) refers to the persistent loss of consciousness after 28 days in patients with brain injury caused by trauma, stroke, or hypoxia. It includes coma, vegetative state, and minimally conscious state. At present, there is no effective treatment for DOC. Only one RCT study of amantadine has proved that it may be effective for the treatment of DOC. In recent years, more evidence has shown that neuromodulation technology is beneficial to the recovery of DOC. Cervical spinal cord stimulation surgery is a new treatment method for patients with DOC. Electrodes are implanted in the high cervical spinal cord C2-C5. By adjusting different electrical stimulation parameters, it has a wake-promoting effect. In this study, patients were selected into the spinal cord stimulation group and the conventional treatment group according to the wishes of their families. The patients in the spinal cord stimulation group were given 21 days of cervical spinal cord stimulation treatment on the basis of conventional brain rehabilitation. Patients were followed up routinely and completed designated examinations at 12 months to determine the safety and efficacy of cervical spinal cord stimulation therapy.
The goal of this clinical trial is to compare the effect of high chlorine solution such as normal saline and non-high chlorine solution such as sodium lactate ringer's solution on renal function in patients with heat stroke. The main question it aims to answer is whether limiting the amount of normal saline infusion during emergency department can lower the incidence of acute kidney injury and mortality in patients with heat stroke. Participants will receive a free normal saline infusion during the emergency department according to the study design, or a restricted normal saline infusion while using sodium lactate Ringer's instead. Researchers will compare the normal saline infusion group and sodium lactate Ringer's group to see if limiting the amount of normal saline infusion during emergency department can lower the incidence of acute kidney injury and mortality in patients with heat stroke.
The goal of this observational study is to explore the optimal target body temperature in first 24 hours and the relationship between body temperature and adverse outcomes of heat stroke. The main questions it aims to answer are: - the optimal target body temperature at 0.5 h, 2 h, and the lowest body temperature of heat stroke. - the best body temperature at the cutting point of stop cooling. - The relationship between the volume and speed of ice saline infusion and the cooling effect.
A 6-month pilot randomized controlled trial designed to test the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diet + usual medical care versus usual medical care on the rate of cognitive change and several other secondary outcomes through a randomized controlled trial in 60 mild stroke patients aged 35-70 years without dementia.
Cerebrovascular accident makes adults lose the ability to be independent in daily life, and a higher proportion of them will suffer from dysphagia. Previous studies pointed out that the tongue muscle strength of stroke patients is significantly lower than that of healthy adults. Furthermore, the tongue strength of stroke patients with dysphagia is significantly lower than those without dysphagia. Many studies investigated the performance of tongue function in healthy adults or groups with dysphagia caused by different diseases. However, the current research on the performance of tongue function in healthy adults and stroke patients in Taiwan is relatively lacking. Therefore, our purpose of this study is to investigate the performance and differences of tongue function between healthy adults and strokes patients in Taiwan. This study is expected to recruit 32 healthy adults and stroke patients in each group. The two groups will be matched with each other by gender and age (±2 years). In the study, Mann assessment of swallowing ability (MASA) will be used as an assessment tool to distinguish whether the subjects are accompany with dysphagia and the severity of dysphagia. And using Iowa Oral Performance Instrument (IOPI) to measure the value of tongue pressure. Then, analyze whether there are significant differences and the correlations. To provide clinicians with empirical data for early detection and intervention of swallowing.
Establish a clinical cohort of acute ischemic stroke patients and find the determinant of the prognosis.
Endovascular thrombectomy (EVT) is a highly effective therapy for acute ischemic stroke with large vessel occlusion (LVO). EVT was proven efficacious in selected patients with symptoms onset or last-known-well time of up to 24 hours. With a number-needed-to-treat (NNT) of 2.3-2.8 to achieve functional independence, EVT had become the current state-of-the-art treatment for ischemic stroke with LVO. Nevertheless, more than half of LVO strokes suffered from functional dependence or death despite EVT. Futile EVTs were contributed by peri-procedural malignant brain edema (MBE) and symptomatic intracranial hemorrhage (sICH). Studies suggested that 26.9% of EVTs were complicated by MBE, whereas sICH was present in 6-9% of LVO patients who received EVT. The fundamental pathophysiology of MBE and sICH is blood-brain-barrier (BBB) disruption secondary to ischemia, mechanical and reperfusion injury. These pathological processes can result in increased tissue permeability, excess production of oxygen free radicals and inflammatory response that eventually lead to hemorrhage and edema. Poor collateral circulation, proximal LVOs, intravenous thrombolysis, blood pressure and glucose fluctuation had all been implicated to in MBE and sICH. However, these risk factors were either unmodifiable or not shown to improve EVT outcomes. The preliminary results of a recent randomized trial even suggested harmful effects of intensive blood pressure following EVT. With indications of EVT are expanding to patients with prolonged ischemia and large ischemic cores, enhancing BBB and neuronal tolerance to ischemia and reperfusion therapies may hugely impact on EVT outcomes. Recent animal models have shown that glucagon-like peptide peptide-1 receptor agonists (GLP-1RA) significantly reduced infarct volume and neurological deficits following temporary or permanent middle cerebral artery occlusion. These effects were likely due to the anti-oxidant, anti-inflammatory and anti-apoptotic properties of GLP-1RA that protected BBB integrity and ischemic neurons during induced LVO and/or reperfusion. Investigator hypothesizes that compared to standard reperfusion strategies, administration of GLP-1RA in LVO patients who receive EVT may prevent the development of MBE and sICH, and improve neurological outcomes. In this randomized, open-label pilot study, investigator aims to determine the effect of semaglutide, a GLP-1RA, on the radiological and clinical outcomes in LVO patients undergoing EVT.
In stroke patients, the shoulder-upper extremity complex is affected and reduces independence and quality in activities of daily living. Investigating the relationship between the functions of the upper extremity muscles and viscoelastic properties is important in understanding the rehabilitation of individuals with stroke.
