There are about 4372 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.
Primary objective of this study is to identify the optimal task lighting conditions (in terms of light intensity and light temperature) for 10 activities of daily living (ADLs) that require near or intermediate vision acuity in a validated ADL simulation framework for a sample of patients who underwent presbyopic correction with bilateral multifocal intraocular lenses (IOLs) implantation, and to compare their capacity to perform ADLs (ADL scores) between three study groups (SG): SG1. patients implanted bilaterally with trifocal diffractive IOLs, SG2. patients implanted bilaterally with bifocal hybrid (diffractive-refractive) IOLs, SG3. patients implanted bilaterally with monofocal IOLs
Primary objective of this study is the validation of the Catquest-9SF questionnaire in the Greek population.
The purpose of the study was to examine the emotional state of the patients with neurological disorders. The evaluation was conducted with DASS-21 scale over 40 patients.
Primary objective of this study is to study the efficacy of travoprost without preservatives in the treatment of glaucoma patients and to monitor the ocular surface.
Previous data have shown that integrated information from single nucleotide polymorphisms (SNPs) of the host DNA, interleukin 8 (IL-8) and the enrichment of the stool microbiome can indicate the patients with infection by Clostridioides difficile (CDI) who are at risk for unfavorable outcome. This integrated information is forming the BEYOND score. The aim of the BEYOND randomized clinical trial (RCT) is to investigate if adjunctive bezlotoxumab treatment to the current standard-of-care may decrease the likelihood of unfavorable outcome for patients who score positive by the BEYOND score.
Colon cancer is internationally the third cause of deaths from a malignant disease. Screening colonoscopy in adults >45 years of age aims at the early diagnosis and treatment colon polyps that are precancerous lesions. Endoscopic polyp removal (polypectomy) can be done with various techniques depending on the size, morphology, location of the polyp etc. According to updated guidelines, non-pedunculated polyps of small size are treated with a cold snare in air dilated intestinal lumen (conventional cold snare polypectomy - CCSP).In recent years, several studies have described the benefits of water aided colonoscopy, as well as safety and efficacy of underwater polypectomy in large colon polyps. However, there is not enough data on small polyps which are the most commonly diagnosed.This is a prospective randomized double-blind clinical trial to compare the safety and efficacy of CCSP to underwater cold snare polypectomy (UCSP)for non-pedunculated polyps of size of 5-10 mm. A total of 398 polyps will be randomized and randomization will be performed via random numbers method of Microsoft Excel 2016. Primary outcome of this study is to determine muscularis mucosa resection rate. Secondary outcomes are the depth and percentage of R0 excisions and possible complications. The investigators expect UCSP to ensure a higher muscularis mucosa resection rate and they attempt to examine the resection depth in the submucosal layer.These results will provide useful data for the development of guidelines in polypectomy techniques for non-pedunculated polyps 5-10mm.
This study was designed to investigate the efficacy of flow cytometry to accurately identify between normal and cancer cells in colon epithelium in humans diagnosed with colorectal cancer.
This study is a randomized, double-blind, placebo-controlled, phase III, three-way crossover clinical trial evaluating the efficacy and safety of KVD900, in the treatment of hereditary angioedema attacks in adolescent and adult Patients
This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to semaglutide taken once a week in people with type 2 diabetes. The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to semaglutide. Participants will either get IcoSema or semaglutide. Which treatment participants get is decided by chance. IcoSema is a new medicine that doctors cannot prescribe. Doctors can already prescribe semaglutide in many countries. Participants will get IcoSema or semaglutide, which they must inject once a week with a pen, which has a small needle, in a skin fold in the thigh, upper arm, or stomach. The study will last for about 1 year and 1 month. Participants will have 18 clinic visits, 34 phone/video calls with the study doctor, and 4 contacts with the site that can either be clinic visits or phone/video calls. At 11 clinic visits participants will have blood samples taken. At 7 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit. Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period.
