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.
The investigators prospectively evaluated long-term outcomes of ELBPD+EST for CBD stones up to 8-12mm. EPBD+EST in patients with CBD stones up to 8-12mm appears to be associated with a very low (<3%) rate of long-term stone recurrence. The efficacy of EPBD for 8-12mm stones warrants further exploration in randomized trials.
Primary objective of this study is the exploration of the impact of personality type, social roles and working mandates οn the visual capacity and satisfaction of patients that underwent pseudophakic presbyopic correction.
This study is open to adults with chronic kidney disease. People with and without type 2 diabetes can take part in this study. The purpose of this study is to find out whether a medicine called BI 690517 improves kidney function in people with chronic kidney disease when taken alone or in combination with a medicine called empagliflozin. In the first part of the study, participants take empagliflozin or placebo as tablets every day for 2 months. Placebo tablets look like empagliflozin tablets but do not contain any medicine. In the second part, participants are divided into several groups. Depending on the group, the participants then additionally take different doses of BI 690517 or placebo as tablets for 3.5 months. In this case, placebo tablets look like BI 690517 tablets but do not contain any medicine. Participants are in the study for about 6 months. During this time, they visit the study site about 12 times. Where possible, about 4 of the 12 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Participants collect urine samples at home. These samples are then analysed to assess kidney function. At the end of the trial the results are compared between the different groups. The doctors also regularly check participants' health and take note of any unwanted effects.
The aim of the present randomized trial is to assess the efficacy of wound drains in terms of reducing the rates of surgical site infection in obese patients with gynecological cancer.
This descriptive, cross sectional study aims to investigate the knowledge, attitudes, intentions, abilities, and behavior of physicians who manage patients with chronic, non-communicable, diseases about physical activity and exercise. The sample will be nationwide and consisted of about 20.350 physicians of all the 13 Greek Regions. An anonymous, coded and self- administered questionnaire will be used as the main research tool for measuring the knowledge, attitudes, intentions, abilities and behavior of physicians. The questionnaire will be developed via the Delphi method after a systematic literature review and a focus group. The construction of the main questionnaire via the Delphi method, will include 2-3 quantitative rounds of data collection by 16 experts. The experts, who will be physicians and have knowledge and experience in matters related to physical activity, exercise and chronic diseases, will be selected based on specific criteria. Once the questionnaire has been developed, it will be piloted on a sample of approximately 40-50 physicians - different from that of the study. Then it will be sent to the physicians of the main study. Beside the main questionnaire, the Greek Edition of International Physical Activity Assessment Questionnaire (International Physical Activity Questionnaire-Short, IPAQ), will be also provided to the physicians to evaluate their levels of physical activity. Both the questionnaires will be completed online, via electronic form (google), because of the Covid-19 pandemic. The questionnaires and the information letter will be sent electronically to the participants through the Panhellenic Medical Association. This study has been approved by the Bioethics and Ethics Committee of the School of Medicine of National and Kapodistrian University of Athens.
Multiple sclerosis (MS) is a chronic immune-mediated neurodegenerative disease that affects the central nervous system (CNS). The exact pathophysiology of MS remains unclear; it is suggested that the inflammatory state persists under a genetic-energetic-environmental complex causing a variety of clinical symptoms depending on the neuroanatomical location of MS lesions. The age of MS onset ranges between 20 and 40 years. MS is usually initiated as a relapsing-remitting disease, which may last several years to decades affecting females twice as often as males. Dietary factors may have an important impact on MS. Data from human and animal studies indicate that saturated fatty acids (SFA), the major fat type of animal foods in the "Western" diet, increase MS susceptibility. The Mediterranean dietary (MedDiet) pattern is hypothesized to be beneficial to MS patients protecting against the development cardiovascular diseases. However, little is known about the cardiovascular effects of the MedDiet on MS patients. Consequently, the aim of the present randomized, case control study was to investigate the effects of MedDiet on cardiovascular factors in women with relapsing-remitting MS after a 3-month intervention period.
The purpose of this study is to assess the safety, efficacy, tolerability, and toxicity of docetaxel alone, in combination with BMS-986218, or in combination with nivolumab plus BMS-986218 in men who have metastatic castration-resistant prostate cancer (mCRPC) that progressed after novel antiandrogen therapy and have not received chemotherapy for mCRPC.
This is a single-arm, open-label study to assess the pharmacokinetics, pharmacodynamics, safety, and exploratory efficacy of tocilizumab (TCZ) for the treatment of pediatric patients from birth to less than 18 years old hospitalized with COVID-19 and who are receiving systemic corticosteroids and require supplemental oxygen or mechanical ventilation.
Eosinophilic inflammation in the small airways of patients with severe asthma is considered to be an important marker of disease severity. In clinical trials, treatment with mepolizumab reduces exacerbation rates by almost a half along with modest improvements in symptom scores and forced expiratory volume in 1 s (FEV1) early after the first month of commencing mepolizumab treatment. However, there is an apparent discrepancy between major patient-reported outcomes and lung function that should be explored. It has recently been reported that mepolizumab improves small airway function in severe eosinophilic asthma as detected by multiple-breath nitrogen washout test. The improvement in small airway function was seen rapidly after the first mepolizumab injection and was associated with a sustained response in the majority of patients. However, gaps in knowledge about the choice of device, gas, and standardization across systems are key issues leading the committee to conclude that multiple-breath nitrogen washout test is not ready for use as a clinical trial endpoint in asthmatics. The investigators hypothesize that early improvement in small airway function may be a significant contributor to the therapeutic response of anti-IL-5 monoclonal antibody therapy in patients with severe uncontrolled eosinophilic asthma. The investigators speculate that SAD could be effectively evaluated using IOS. Consequently, this study could lead to novel SAD subtypes with possible clinical relevance in the context of treatment with anti-IL-5 factor. The investigators hypothesize that healthy individuals and patients with severe controlled asthma would disclose a lesser extent of SAD than patients with severe uncontrolled eosinophilic asthma with or without fixed airway obstruction.
Early research suggests that inflammation plays a key role in the development of SARS CoV-2 infection. The immune response to respiratory infection is characterized by an influx of neutrophils to the lungs. This study ought to investigate the association of simple biomarkers such as NLR and PLR with the clinical outcome in SARS CoV-2 infection patients.
