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.
This study compares how three doses of semaglutide work in participants with type 2 diabetes (T2D) and overweight who are taking metformin. The study will look mainly at how well participant's blood sugar and participant's body weight are controlled when they are taking the study medicine at different doses. Participants will either get semaglutide [2 milligrams (mg), 8 mg, or 16 mg] or semaglutide placebo (a dummy medicine). Participants will take the study medicine with an injection pen called NovoPen®4. The injection pen is a medical tool with a needle used to inject the study medicine under the skin. The study will last for about 52 weeks. Participants will have 13 clinic visits and 4 phone calls.
This study investigated the effects of two different doses of Crocus Sativus in glucose beverages on glycemic responses.
This study investigated the effects of three doses of spirulina in glucose beverages on postprandial glycemic responses, arterial blood pressure, and subjective satiety.
This study investigated the effects of cookies containing 2.5 g Spirulina on postprandial glycemic and insulin responses.
HIV CoCo is a European multi-centre, multi-country, retrospective, observational case-control study that will aim to describe clinical outcomes and identify risk factors for People Living With HIV (PLWHIV) who are co-infected with the SARS-CoV-2 coronavirus. The study will address two central questions: 1. Is there a particular risk for COVID-19 in PLWHIV as compared to HIV seronegative control COVID-19 cases? 2. Are there particular factors, within the group of PLWHIV, which put them at risk for a more severe COVID-19 disease course? The study will address these questions by recruiting patients co-infected with both HIV and SARS-CoV-2 and comparing them to two control groups - one group infected with SARS-CoV-2 only and another group infected with HIV only. Only deidentified, real-world retrospective data will be used for the study, collected as part of standard, routine clinical care. Additionally, this study will also look to: 1. Describe the differences in the clinical manifestation of COVID-19 in PLWHIV compared to HIV seronegative controls 2. Describe the response to treatment, including supportive care and novel therapies against COVID-19, including antiviral or immunomodulatory therapy 3. Describe the co-morbidities in PLWHIV and controls with COVID-19 4. Compare the severity of COVID-19 between PLWHIV and the COVID-19 only controls at diagnosis and hospital admission. Data will be collected about patient outcomes from COVID-19 (including hospitalisation for COVID-19, length of stay in hospital, critical care admission, ventilation/oxygenation requirements, and need for kidney replacement therapy), as well as pre-existing health conditions, and relevant blood results at COVID-19 diagnosis.
A randomized controlled study to examine the effect of a nurse-led, home/telephone or telephone-only educational intervention on outcomes of heart failure patients and their caregivers.
The purpose of this study is to evaluate whether the addition of follicular flushing to the initial aspiration during oocyte retrieval increases the number of oocytes retrieved in women undergoing ovarian stimulation.
The applications of point-of-care ultrasonography (POCUS) of the upper airway are growing over the last decade. It's clinical applications include both diagnosis of upper airway pathology as well as pre-intubation airway examination and provision of ultrasound markers of difficult laryngoscopy and/or intubation. However, it is differentiated from the comprehensive ultrasound examinations traditionally performed by radiologists because it is targeted to answer a specific clinical question in real time. Moreover, ultrasound-guided techniques require knowledge of sonoanatomy and ultrasound operational skills. However, clinicians lack the standardized training that ultrasound technicians and radiologists receive. POCUS training is rarely done in a standardized manner, and even more so, POCUS is rarely conducted under expert's supervision. The current study investigates the feasibility of upper airway POCUS performed on healthy volunteers by anaesthesia residents using a predefined scanning protocol after attending a structured training course. Assessment of anaesthesia trainees' competence and minimum training requirements were the aim of the study.
The purpose of this study is to examine the effect of long-term carbohydrate periodization protocols on sleep architecture, sleep quality, daytime sleepiness, physical performance, body composition, gut microbiome, and miRNA in healthy trained individuals.
Our study aimed at assessing the changes of portal vein pressure, portal vein flow and hepatic arterial flow (HAF) in liver remnants ≤ 30% of the standard liver volume by reducing portal vein overflow via ligation of the splenic artery.
