Filter by:Coronary artery disease is one of the biggest health issue worldwide.The treatment, in a large part of the patients, implicates a so called bypass-operation, that consists in to connect new vascular conduits (grafts) beyond the narrowed coronary vessels to improve the blood supply to the heart. One of the graft that is commonly used is the saphenous vein from the leg. The disadvantage of the saphenous vein graft is the predisposition to early obstruction. The international literature shows the following grades of occlusion: 15% in the first year and 40% after 10 year. At the Cardio-Thoracic Clinic of the University hospital of Örebro has been developed a new method to harvest the saphenous vein together with the surrounding fat-tissue. This technique, called no-touch technique, has the advantage to reduce the damages to the vein during the harvesting, showing a substantially reduced risk for future occlusion (5% after 18 months and 10% after 8,5 years). The aim of the PhD project is to evaluate the results of the no-touch technique in compare to the conventional technique for the venous graft harvesting. The focus of the study is to analyse all the operated patients in our clinic who underwent a post-operative coronary angiography do to angina pectoris (heart pain). All the patients who received a stent during the post-operative angiography will be analysed in detail and one will compare the occlusion grade and the rate of major adverse cardiac events (MACE). This study is the first and the only one in the world that will examine the long-term results of the no-touch technique in particular after the stenting of the venous graft.
This study is a prospective, randomized, single-blinded, cross-over trial to investigate the efficacy of low-intensity extracorporeal shockwave therapy in the treatment of erectile dysfunction (ED). We will enroll 60 subjects (International Index of Erectile Function Questionnaires, 5 ≦ IIEF-5 ≦ 21). 30 subjects receive ESWT (LM-IASO, Litemed Co., Taiwan) for 6 courses in 3 weeks (0.05mJ/mm2, 3000 pulses) and 30 subjects receive Sham therapy for 3 weeks (the machine turning on but the energy is zero). After 3 weeks, the two groups are cross over. The primary outcome is the 4th week change from baseline for IIEF-5 score. Secondary outcomes are the 8th week change from baseline for IIEF-5 score, EHS, QoL; AEs. The between-group relationships of baseline and 4-week data were evaluated by using the Student's t-test or Mann-Whitney U-test where appropriate. Multiple linear regression was carried out to test the variables associated with treatment outcome. P-values < 0.05 were considered statistically significant.
Participants are free to decide if they want to take part in this study or not. The study will be conducted to collect information about the influence of adherence to growth hormone therapy with Norditropin® in children and teenagers in daily practice in Germany. This study will look mainly at the difference in near final height between children and teenagers who adhere to their therapy plan with Norditropin® to non-adherent patients. Participants will get Norditropin® as prescribed to them by their doctor. The study will last as long as the therapy with growth hormone is seen necessary by the participants' doctors and the participants, up to a maximum of 10 years. During the visits at the participants' doctors participants will be asked to fill in a questionnaire.
This study aims to evaluate the electrophysiological properties of the heart conduction system in patients with unexplained polymorphic ventricular tachycardia (VT) and/or ventricular fibrillation (VF), in patients with specific genetic mutations regarding sudden cardiac death or sudden cardiac arrest, in their family members and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Also a National Dutch registry for patients with unexplained polymorphic VT and/or VF and their family members will be created. By combining the data from the registry and the results of ECGI, The investigators hope to identity risk markers for patients at higher risk for apparently idiopathic ventricular fibrillation, and use these for an adapted flow chart for the 'general'population of patients at risk for unexplained polymorphic VT and/or VF. The investigators aim to be able to identify patients before the first arrhythmic event, and aim for better treatment strategies in the future.
52 Week Open-Label Safety Study of Cenobamate for Subjects who Complete YKP3089C025 (core study)
The purpose of this study is to assess the interobserver agreement (IOV) for pancreatico-biliary Volumetric Laser Endomicroscopy (VLE) de-identified clips using the new VLE criteria. This is an Interobserver study to validate VLE criteria for indeterminate biliary and pancreatic duct strictures and evaluate impact on clinical management.
This phase II trial studies how well estradiol works in treating patients with estrogen receptor beta (ER beta) positive, triple negative breast cancer that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Hormone receptors like ER beta allow the body to respond appropriately to hormones. Triple negative means that the breast cancer does not express other hormone receptors called ER alpha, progesterone, and HER2. In some people with triple negative breast cancer, ER beta is overexpressed. Tumor cells that overexpress ER beta grow slower in the laboratory and this growth is slowed in the presence of estrogen. Estradiol is a form of estrogen. This study may help doctors determine whether tumor cells that overexpress ER beta shrink in the presence of estradiol.
Investigators investigates the effect of perioperative dexmedetomidine 0.5 ug/kg/hr followed by a postoperative continuous infusion fentanyl-based PCA(Patient-Controlled Analgesia) drug mixed with dexmedetomidine 0.2ug/kg/hr for two days on reducing postoperative delirium and postoperative rescue analgesics in elderly patients who undergo hip surgery. The other half of patients received fentanyl-based PCA only.
Recently the new concept of "mechanical power" has been proposed. It refers to the amount of energy per minute that is transferred to the lung by the ventilator. The generation of this form of energy would include both parameters that were previously proposed to be possible causes for lung damage and new parameters that had not been taken into account until now, such as the flow rate or the respiratory rate, without forgetting the individual characteristics of each ventilated subject. The main objective of the current study is to know the value of the mechanical power in the patient connected to mechanical ventilation, in a volume control model. This value will be calculated from electronically provided data using the simplified formula by Gattinonni et. al.
This study will compare the efficacy of using standard compression therapy for treatment of chronic venous leg ulcers vs. the standard compression therapy with the additional use of the application of a human allograft (Theraskin)
