There are about 4364 clinical studies being (or have been) conducted in Greece. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Aerobic capacity is critical for many athletes, especially for endurance athletes. Althgough several training methods are implemented by coaches to improve endurance performance, recovery following acute endurance training is not adequately studied. However, such information is crucial for coaches to effectively design the most favorable training program, to avoid muscle injuries and overtraining, and ultimately to improve performance of their athletes. This study aims to examine the acute effect of different continuous and HIIT training protocols on indices of metabolism, EIMD, neuromuscular fatigue and performance in middle- and long-distance runners.
Tumors of the salivary glands occupy 0.5-1.2% of cases of head and neck tumors. They are primarily a surgical disease, as their treatment is basically the surgical excision. In this direction and in the context of the differential preoperative diagnosis, in addition to the imaging methods, the fine needle biopsy (FNA) was used, with which cell material is aspirated from the tumor and studied under the microscope. Although an increasing number of papers have been published in the international scientific literature over the last 5 years on the diagnostic accuracy of FNA in salivary glands, many of them are unable to quantify and omit to refer information that could affect the estimated diagnostic accuracy. Such information is for instance the clinical experience of the doctor who performs the FNA and of the one who assess the smear. The aim of this retrospective study is to evaluate the diagnostic accuracy of fine needle biopsy in adult patients with salivary gland tumor that underwent a surgical excision in two Oral and Maxillofacial Departments in Northern Greece. The present retrospective study was carried out from 2/2021 to 4/2022 by collecting data from the files of patients who underwent surgery at the Oral and Maxillofacial Clinic of the Theageneio Cancer Hospital of Thessaloniki 1996-2022 and the General Hospital of Thessaloniki G. Papanikolaou 2015-2022. The study was conducted according to the STARD 2015 protocol. FNA contributed significantly to the differential preoperative process in salivary gland diseases. The differential diagnosis of a lesion in benign / malignant preoperatively, with the use of FNA, enables the surgeon for a more beneficial to the patient and oncologically safer planning of the surgery. It is considered important the high sensitivity provided by the examination, as it helps to exclude with sufficient safety the possible malignancy of the tumor located in the salivary gland of the patient.
The trial is a pivotal clinical investigation, which is a prospective, non-randomized pivotal clinical investigation to demonstrate the safety and performance of the TrueCross Single-use Microcatheter.
The purpose of this study is to evaluate the effect of different flow rates during oocyte retrieval, on the number of cumulus oocyte complexes (COCs) retrieved.
To investigate the efficacy of Superoxide Dismutase (SOD, 70 UI), Palmitoylethanolamide (PEA, 300 mg) Alpha Lipoic Acid (ALA, 300 mg), vitamins B6 (1.5 mg), B1 (1.1 mg), B12 (2.5 mcg), E (7.5 mg), Nicotinamide (9 mg) and minerals (Mg 30 mg, Zn 2,5 mg) in one tablet in patients with Diabetic Neuropathy (DN).
The goal of this randomised controlled trial is to learn about the effect of therapeutic climbing in hemiplegic children. The main questions it aims to answer are: Does climbing affect muscle strength and tone? What is its connection between normative data drawn from healthy children? How can it affect balance? Participants (children) will be asked to complete an series of movements used in sports climbing, such as inside-flag, back-flag and horizontal traverse, while hanging on an in-door climbing wall.
Background: People with Parkinson's disease (PD), including parkinsonisms, experience complex motor and non-motor symptoms, which become more hindering in the advanced stages of PD. Advance care planning (ACP) enables individuals to define goals and preferences for future medical treatment and serves to ensure that people receive treatment and care that is in line with their preferences during serious chronic illness. The effectiveness of ACP for PD is currently unknown. Methods: The investigators will evaluate the effectiveness of a multicenter, open-label randomized controlled trial, with a parallel group design in seven European countries (Austria, Estonia, Germany, Greece, Italy, Sweden and United Kingdom). The "PD_Pal intervention" comprises (1) several consultations with a trained nurse who will perform ACP conversations and support care coordination and (2) use of a patient-directed "Parkinson Support Plan-workbook". The intervention group will be compared to a care-as-usual group. Documented ACP-decisions in the medical records/patient's central file assessed at 6 months after baseline will be the primary endpoint. Secondary endpoints include patients' and family caregivers' quality of life, perceived care coordination, patients' symptom burden, and cost-effectiveness. Assessments will take place at baseline, 6 months after baseline and 12 months after baseline. In parallel, we will perform a process evaluation, to understand the feasibility of the intervention. Hypothesis: The investigators hypothesize that the PD_Pal intervention will result in an increased number of participants with ACP documentation in the medical records/patient's central file, as compared to care-as-usual. Secondly, the investigators expect that, due to the PD_Pal intervention, patients and their FC will experience better care coordination, better quality of life, a reduced patient symptom burden and the FC will experience a reduction in caregiver burden.
The goal of this clinical study is to compare the therapeutic effect of Dulaglutide and Empagliflozin in patients with Diabetes Mellitus type 2 and Non-Alcoholic Fatty Liver Disease. The main question it aims to answer is: Is there a beneficial effect regarding liver steatosis in patients receiving either of these 2 medications and which is more effective? Patients will undergo shearwave elastography, magnetic resonance imaging, and ultrasound. Furthermore, calculation of the Fatty Liver Index (FLI), the Fibrosis-4 Index (FIB-4), as well as the Aspartate Aminotransferase to Platelet ratio Index (APRI) and the NAFLD Fibrosis Score (NFS) will be performed. Researchers will compare 3 groups: Group 1 will receive oral Empagliflozin, as add-on to their previous treatment regimen, for 52 weeks. Group 2 will receive subcutaneous Dulaglutide, as add-on to their previous treatment regimen, for 52 weeks. Group 3 will receive other optimal antidiabetic treatment (apart from agents of the GLP1-ras or SGLT2-is families) for 52 weeks.
The goal of this clinical trial is to compare the anticoagulation management with or without heparin concentration level guidance, in patients undergoing valve or complex cardiac surgery during cardiopulmonary bypass using closed, coated circuits. The main questions it aims to answer are: - initial heparin bolus, subsequent supplementary doses and total heparin variance among groups. - protamine dose among groups. Participants are adult patients scheduled for valve or complex cardiac surgery. They are randomised to either Activated Clotting Time guided management alone or combined with heparin level concentration monitoring.
