Clinical trials

Objectives of the study The aim of the study is to investigate and compare the treatment efficacy and safety of Oxiblume:CoQ10 (Ralivia) therapy vs placebo for BPH patients Study center The study will be coordinated by the research office of 1st Urology Department, G. Gennimatas Hospital, Aristotle University of Thessaloniki, Greece. The research office will also support the project (logistics, quality control, management, data acquisition, publications). Patients visits will be carried out in the BPH Research Unit of the 1st Urology Department, G. Gennimatas Hospital, Aristotle University of Thessaloniki, Greece. Laboratory tests of all patients will be performed at the same microbiology laboratory. Study population A total of 100 patients (50 in Group A and 50 in Group B) with BPH diagnosis will participate in this study. Study design Double-blind placebo-controlled randomized clinical trial Zero hypothesis (H0) and alternative hypothesis (H1): (H0): Group A demonstrates similar efficacy compared to Group B for the treatment of BPH patients.

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) has a huge socioeconomic impact.Presently, a ''scientific dead-end'' regarding effective treatment of CP/CPPS is reported. Promising results of clinical studies, regardless their limitations, upon efficacy of phytotherapy for CP/CPPS patients have been published .Phytotherapy is cost effective and avoids the systemic side effects of other treatments being a therapy with the possibility of repeating the treatment protocol at any time. Certain important issues, regarding the efficacy and safety of phytotherapy, remain to be answered thus investing scientifically and economically to the concept of phytotherapy for CP/CPPS, definitively seems to be a move to the right direction. In this concept we will conduct a double-blind placebo-controlled randomized clinical trial assessing treatment efficacy and safety of Oxiblume:CoQ10 (Ralivia) therapy for CP/CPPS The study will be coordinated by the research office of 1st Urology Department, G. Gennimatas Hospital, Aristotle University of Thessaloniki, Greece. The research office will also support the project (logistics, quality control, management, data acquisition, publications). Patients visits will be carried out in the CP/CPPS Research Unit of the 1st Urology Department, G. Gennimatas Hospital, Aristotle University of Thessaloniki, Greece. Laboratory tests of all patients will be performed at the same microbiology laboratory. Study population A total of 100 patients (50 in Group A and 50 in Group B) with CP/CPPS diagnosis will participate in this study. Inclusion and exclusion criteria Inclusion criteria: 1. Participant must be between 18 and 50 years old. 2. Participant has signed and dated the appropriate Informed Consent document. 3. Participant has had a clinical diagnosis of CP/CPPS defined as symptoms of discomfort or pain in the perineal or pelvic region for at least a three (3) month period within the last six (6) months.

Participant has undergone prostate surgery or treatment. 7. Participant with penile or urinary sphincter implants. 8. Participant has been diagnosed with cancer during the last 5 years or had any surgery in the pelvis. 9. Participant has a neurological impairment or psychiatric disorder preventing his understanding of consent and his ability to comply with the protocol. Study design Double-blind placebo-controlled randomized clinical trial Zero hypothesis (H0) and alternative hypothesis (H1): (H0): Group A demonstrates similar efficacy compared to Group B for the treatment CP/CPPS patients. (H1): Group A demonstrates greater or decreased efficacy compared to Group B for the treatment CP/CPPS patients.

Secondary endpoints: * Adverse events rate in all patients during study period. * The difference between the Group A and Group B in the change of the pain domain of NIH-CPSI score from baseline to 6 weeks after treatment start. * The difference between the Group A and Group B in the change of the following parameters from baseline to 6 and 12 weeks after treatment initiation 1.

The goal of this clinical trial is to compare the effects of Opioid Free Anesthesia (OFA) with and without volatile anesthetics (in this case desflurane) in patients undergoing bariatric surgery. The main question it aims to answer : -Will there be a difference in the perioperative stress between patients receiving OFA with and without desflurane? Participants will undergoing sleeve gastrectomy or gastric by pass, will be administered OFA with and without desflurane and blood tests (cortisole, ACTH,dopamine, PRL, adrenaline, noradrenaline, lactate) will be collected perioperatively to compare stress in the two groups.

The goal of this clinical trial is to compare Opioid Free and Opioid Based Anaesthesia in patients undergoing sleeve gastrectomy. The main questions it aims to answer are: * Will the total dose of intraoperative opioid be reduced? * Will there be difference in pain scores between groups? Participants will be managed with the Nociceptive Level Index algorithm to guide intraoperative analgesia. The Opioid Free Anaesthesia Group will be administered the Multimix infusion (Magnesium sulfate, dexmedetomidine, ketamine). The Opioid Based Anaesthesia Group will receive fentanyl as a bolus dose and remifentanil infusion. Rescue fentanyl bolused will be injected as appropriate according to nociceptive level (NOL) values.

Up to this date, there have been no reports on virtual reality (VR) training in thyroid surgery. The purpose of this study is to determine the impact of VR training in residents' education. Investigators intend to include general surgery residents in the trial, subgrouped in a VR training group and another one with traditional learning, utilizing a technical textbook as a control. For the purpose of this study, a commercial available VR mask will be given for training in the VR group. Randomization will be used to secure balance in the distribution of residents according to their experience. The task which will be examined include surgical steps from neck incision up to the placement of the C-IONM electrode and will be evaluated by a blinded FEBS certified endocrine surgeon in the operating theatre. Training superiority will be assessed by the outcome measures of Objective Structured Assessment of Technical Skills (OSATS) score, need for the main surgeon to intervene (NTI), verbal answers and time to task completion. Participants will complete questionnaires regarding satisfaction of the whole educational process.
