Filter by:The objectives of this study are to determine the: 1. Diagnostic value of stress induced RV changes on Lexiscan stress MPI as compared to Exercise stress MPI in predicting a significant CAD. 2. Prognostic value of stress induced RV changes on Lexiscan stress MPI in predicting adverse short-term and long-term clinical outcomes after the index test.
Magnetic Resonance guided Focused Ultrasound (MRgFUS) has demonstrated to be effective for pain control through thermally-induced cell death and periosteal denervation caused by cortical heating relative to acoustic energy absorption. There is also evidence that a high intensity focused ultrasound beam can penetrate through the cortical bone to the medullary space, producing thermal necrosis of cancer tissue. However, little is known about the potential effects of MRgFUS as first line therapeutic modality for pain palliation in skeletal metastases. Our hypothesis sought to assess the clinical performance of MRgFUS primary treatment of painful bone metastases and determine the potential of this technique for local tumor control.
Chronic right ventricular apical pacing has been associated with negative hemodynamic effects. Clinical outcome of right ventricular pacing can be influenced by multiple factors. An important factor seems to be optimal lead positioning. Data regarding left ventricular function impaired by lead positioning is insufficient. The aim of the present study therefore is to compare right ventricular apical pacing (RVAP) with right ventricular septal pacing (RVSP). Outcome measurements are echocardiographic features, magnetic resonance imaging and clinical outcome.
Percutaneous vertebroplasty (PVP) is now a therapeutic option for individuals for whom medical management has not been successful or for those who are at risk for developing complications due to long-term immobilization. Recently, three randomized controlled trials (RCT) concerning PVP have been published with conflicting results. Two RCTs with a sham control intervention failed to show an advantage of vertebroplasty over placebo for participants with acute, subacute, and chronic fractures or severe pain. In the third RCT, PVP compared to optimal conservative treatment showed significant immediate postoperative pain relief in the vertebroplasty group, but not at 3 and 12 months. To examine these issues, this study is initiated to compare PVP with conservative therapy in patients with osteoporotic VCFs. Moreover, this study addresses concerns about the possibility that PVP increases the incidence of new compression fractures in adjacent vertebrae.
The purpose of this post-approval study of the EXCOR® Pediatric VAD is to evaluate whether safety and outcomes of the device use in the commercial setting are comparable to the safety and outcomes of the device use in the IDE study.
Study Design: Patients are eligible if (1) enrolled to TCOG 3207(2) received surgery or biopsy for pancreatic cancer; (3) willing to sign informed consent. The pancreatic tumor, tissue specimen and blood sample before or after treatment will be collected from department of pathology, surgery or diagnostic medicine.
Previous studies using transcranial magnetic stimulation (TMS) with paired pulse protocols have shown that a conditioning TMS pulse applied to the human motor cortex changes the excitability of motor pathways from the motor cortex to spinal motorneurons. These effects depended on the stimulus intensity of both conditioning and test pulse and also the ISI). A characteristical sequence of inhibition (short interval cortical inhibition [SICI], GABA-Aerg), facilitation (intracortical facilitation [ICF]), and inhibition again (long interval cortical inhibition [LICI], GABA-Berg) is thought to be physiologically involved in motor control. Previous studies have also shown that neuronal inhibitory motor circuits are also disturbed in ADHD which will be restored by using methylphenidate. In this study the investigators sought to investigate if methamphetamine abuse (from the same chemical class of medications) will alter such effects of methylphenidate.
Periodontitis is a destructive chronic infection of the gums, ligaments, and bone, predominantly caused by Gram-negative bacteria. Individuals with periodontal disease are at increased risk of systemic diseases. Increased prevalence of periodontal disease has been reported in patients with chronic kidney disease, especially in dialysis patients. Chronic kidney disease (CKD) is the progressive loss of kidney function over time. When kidneys loose their 85-90 % function, dialysis is performed. Efficacy of dialysis is checked by serum albumin levels. Lower-than-normal levels of serum albumin may be a sign of kidney diseases. Hypoalbuminemia has been demonstrated to be a strong predictor of death in chronic renal failure. A proposed mechanism for the effect of periodontitis on the development of kidney disease is systemic inflammation. The deleterious effects of systemic inflammation on kidney function could occur during the period of active periodontal infection and accumulate during the life time of the individual. This randomized control trial is designed to observe the effect of non-surgical periodontal therapy on serum albumin levels of patients on maintenance hemodialysis therapy. Patients will undergo periodontal examination and their serum albumin levels will be checked. Then they will be randomly divided in two groups. One group will be given non surgical periodontal treatment and second group will be offered late treatment. After 6 weeks 1st group will be reevaluated by serum albumin level and periodontal examination to observe the effect of non-surgical periodontal therapy. Statistical analyses shall be performed using SPSS software. T tests and Chi-sq tests shall be used to test differences according to periodontal status for continuous and categorical variables, respectively. The level of significance is set at p<0.05.
