Filter by:This lifestyle intervention plan will improve healthy lifestyle practices (diet, exercise, and smoking cessation) among stroke survivors and result in a reduction in measures of general and abdominal obesity.
Ventilator-associated pneumonia (VAP) is an important cause of morbidity and mortality in ventilated critically ill patients specially in intensive care unit (ICU). It is associated with an increased duration of mechanical ventilation, high death rates and increased healthcare costs in China. However, VAP is preventable and many practices have been demonstrated to reduce the incidence of this disease, but the morbidity is still so high. So much more methods of prevention should be needed to reduce the incidence of VAP. Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) present anti-inflammatory and immunomodulatory effects besides their ability to regulate cholesterol composition. So it is hypothesized that early use of statin may prevent some of the infection disease such as VAP. Actually, Two studies have showed that statin treatment is associated with reduced risk of pneumonia. However, the relationship between statins and reduced risk of pneumonia is not consistent. After reviewing some of the guidelines,meta analyses and system reviews, the investigator find that advanced age,immune suppression from disease or medication and specially depressed level of consciousness are the risk factors of VAP. So the investigator assumes that early use of statin may give us a favorable outcome in the patients with coma or in the patients with severe disease (Acute Physiology and Chronic Health Evaluation II score > 15 or Glasgow coma score < 7). In addition there is no prospective study to investigate the role of statins in VAP in the patients with ischemic stroke. The investigator hopes that this study can approve the relationship between statins and reduced risk of VAP in the patients with ischemic stroke. And it can improve the processes,outcomes and costs of critical care as well.
Recent studies demonstrated that prolonged rhythm observation increases the detection of atrial fibrillation in patients prior diagnosed as cryptogenic stroke. Detection of atrial fibrillation in these patients has important therapeutic implications for the anticoagulation regimen. However, data on optimal monitoring duration and method of AF detection are limited.
Disturbances in movement coordination are the least well understood but often the most debilitating with respect to functional recovery following stroke. These deficits in coordination are expressed in the form of abnormal muscle synergies and result in limited and stereotypic movement patterns that are functionally disabling. The result of these constraints in muscle synergies is an abnormal coupling between shoulder abduction and elbow flexion (i.e. the flexion synergy), which significantly reduces the reaching function of an individual with stroke when they lift up the weight of the impaired arm against gravity. The investigators previous neurotherapeutic research, supported by a NIDRR Field Initiated research grant, has shown that the abnormal synergy between shoulder abduction and elbow flexion can be significantly reduced thus increasing total reaching range of motion in individuals with severe stroke. The previous work established progressive abduction loading as a key element to the rehabilitation of reaching. Although individuals with severe stroke benefited from the investigators previous work, residual flexion synergy continued to hinder normal arm function in most participants with severe stroke. This study will utilize the ACT3D robot, developed as part of the investigators previous NIDRR project, to incorporate resistance to reaching while accounting for the known benefits of progressive abduction loading. The investigators propose to randomize forty participants with severe stroke into two closely related interventions. The groups will both practice reaching under abduction loading, however, the experimental group will also move against resistance while reaching. Rigorous and quantitative investigation of therapeutic elements such as resistance to reaching and progressive abduction loading is only possible with a device such as the ACT3D. the investigators will be able to standardize the delivery of each intervention using kinematic and kinetic parameters, which will allow for a clear identification of the therapeutic effect of resistance to reaching. the investigators hypothesize that resistance to reaching in combination with progressive abduction loading will further increase dynamic multi-joint strength, increase total reaching range of motion, and increase arm function thus enhancing actual amount of use of the arm, participation in life roles, and quality of life in individuals with severe stroke.
INTRODUCTION: CHIPS-Child is a parallel, ancillary study to the CHIPS randomized controlled trial (RCT). CHIPS is designed to determine whether 'less tight' control [target diastolic BP (dBP) 100mmHg] or 'tight' control [target dBP 85mmHg] of non-proteinuric hypertension in pregnancy is better for the baby without increasing maternal risk. CHIPS-Child is a follow up study at 12 m corrected post-gestational age (± 2 m) limited to non-invasive examination [anthropometry, hair cortisol, buccal swabs for epigenetic testing and a maternal questionnaire about infant feeding practices and background]. Annual contact will be maintained in years 2-5 and contact will include annual parental measurement of the child's height, weight and waist circumference. OBJECTIVE: To directly test, for the first time in humans, whether differential blood pressure (BP) control in pregnancy has developmental programming effects, independent of birthweight. We predict that, like famine or protein malnutrition, 'tight' (vs. 'less tight') control of maternal BP will be associated with fetal under-nutrition and effects will be consistent with developmental programming.
tDCS (transcranial direct current stimulation) will be used in chronic stroke patients to improve a variety of functions with superior or inferior limb.
Although cardio-embolic etiology of ischemic stroke (IS) is largely respected, there is still no clear recommendation for routine complex cardiological examination in all IS patients. Using complex cardiological examination the investigators expect: 1. more accurate detection of patients with concomitant heart disease (cardiac rhythm disorder, valve disorders, acute coronary syndrome, cardiac thrombus and myxoma, atrial and ventricle septum defects) 2. higher number of etiologically determinated IS, which is crucial for accurate secondary prevention.
The purpose of this study is to examine whether 3 weeks of intensive language therapy provided in clinical in- and outpatient settings is effective in improving everyday communication in postacute/chronic post-stroke aphasia, as measured by performance on the Amsterdam Nijmegen Everyday Language Test (ANELT).
The purpose of this study is to investigate whether benefits of training the affected hand in patients with stroke can be improved by combining training with a painless, noninvasive technique called Transcranial Direct Current Stimulation (TDCS). TDCS will be applied over the part of the brain responsible for movements of the affected hand. Also, the investigators will study the changes in the brain that favor recovery of hand function following combination of training and tDCS.
The purpose of this study was to investigate the reliability, construct validity, and sensitivity to change of the Lower Extremity Functional Scale (LEFS) in individuals affected by stroke.
