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 purpose of the present study is to investigate the effects of an in-season mixed training program on several physiological parameters of soccer players. Twenty-one U19 elite soccer players recruited and randomly assigned to either an 8-week specific training experimental group or a control group. The program will include an eccentric hamstring exercise, static balance exercises and core muscles strengthening exercises. Isokinetic hamstring and quadriceps strength, single leg static balance and lumbopelvic stability will be measured prior and after the intervention.
Neck pain is one of the most common and costly musculoskeletal disorders in western societies with a high rate of recurrence and chronicity. In chronic neck pain, the persistence of symptoms is highly associated with changes in the biomechanics of the neck region that are related to the muscular imbalance between the neck muscles and specifically between the deep and superficial neck flexors. Manual techniques are special techniques applied by hand from the therapist that focus on reducing symptoms and improving disability. Both spinal manipulation and soft tissue mobilization techniques have a positive effect in individuals with chronic neck pain, especially when they are combined with the appropriate therapeutic exercise programme. However, it has not been determined which of the above-mentioned combinations is more effective in patients with chronic neck pain. The aim of this study is to compare the efficacy of two different kinds of manual technique, when they combine with the same therapeutic exercise program in the management of patients with chronic neck pain. An assessor-blind randomized control trial with a duration of ten weeks and a 6-month follow up will be performed in 80 women with chronic neck pain. The participants will be allocated into four groups of 20 persons each (three intervention groups and one control group). The first three groups will follow the same exercise program. Only exercise will be applied to the first group. The second group will apply a combination of soft tissue mobilization techniques and exercise. The third group will follow a combination of spinal manipulation and exercise, while the fourth group will not receive any treatment. The neck pain will be evaluated with the visual analogue scale, the disability related to neck pain with the neck disability index, the pressure pain threshold of the neck muscles with pressure algometry, the active range of motion with a bubble inclinometer, the maximum isometric strength of the neck muscles with a hand dynamometer, the muscular fatigue of the flexors of the neck with the craniocervical flexion test and the quality of life with the sf-36 questionnaire before, during and after the intervention, while follow-ups will take place six months later.
The purpose of the study is to assess the safety of BMS-986259 in stable participants hospitalized for acute decompensated heart failure.
This study aims to investigate the potential effects of the administration of hydroxytyrosol, which is an extra virgin olive oil phenolic compound, in doses 15 milligrams and 5 milligrams daily versus placebo for 6 months in anthropometric parameters such as body weight, body fat and visceral fat, in combination with diet, in overweight and obese women.
DisCoVeRy is a randomized controlled trial among adults (≥18-year-old) hospitalized for COVID-19. This study is an adaptive, randomized, open or blinded, depending on the drug to be evaluated, clinical trial to evaluate the safety and efficacy of possible therapeutic agents in hospitalized adult patients diagnosed with COVID-19. The study is a multi-centre/country trial that will be conducted in various sites in Europe with Inserm as sponsor. The study will compare different investigational therapeutic agents to a control group managed with the SoC including corticosteroids and anticoagulants. There will be interim monitoring to allow early stopping for safety and to introduce new therapies as they become available. If one therapy proves to be superior to others in the trial, this treatment may become part of the SoC for comparison(s) with new experimental treatment(s). In previous versions of the DisCoVeRy protocol, remdesivir, lopinavir/ritonavir with or without interferon ß-1a and hydroxychloroquine were evaluated as potential treatments for COVID-19. These treatments have been discontinued based on analyses review by both DSMC/DSMB, the Solidarity Executive Group and the DisCoVeRy steering committee. This version of the protocol, therefore, describes a randomized blinded placebo-controlled trial among adults (≥18-year-old) hospitalized for COVID-19 that randomly allocates them (1:1 ratio) between 2 arms: SoC + placebo versus SoC + AZD7442. Randomization will be stratified by region (according to the administrative definition in each country), antigenic status (positive or negative) obtained from the result of a rapid antigen test on nasopharyngeal swab performed at enrolment and vaccination initiation (yes or no). The primary analyses will be conducted on patients with antigen-positive results. A positive antigenic test is evidence of high viral shedding consistent with a recently started or uncontrolled infection. Overall, the number of antigen-negative patients will be at most 30% of all included subjects. The number of patients with vaccination (partly or fully) will be limited to 20% of all participants, split evenly between antigen positive and antigen negative patients (i.e. vaccinated patients can make up at most 20% of antigene positive patients and 20% of antigene negative patients). Sensitivity analyses will be performed in all patients, stratified by antigenic status and vaccination initiation. A global independent data and safety monitoring board (DSMB) monitors interim data to make recommendations about early study closure or changes to conduct, including adding or removing treatment arms. However, the current version of the protocol does not allow for efficacy or futility analysis, and the ability to add trial arms will be limited by the study being blinded and placebo-controlled during the investigation of AZD7442.
Postoperative neurocognitive disorders, including postoperative delirium (POD) and postoperaive cognitive dysfunction (POCD), are common complications of perioperative neurocognition in elderly patients undergoing surgery. POD and POCD have short- and long-term consequences, such as increased hospital stays and costs, augmented morbidity and mortality, as well as higher risk for cognitive decline later in life. Therefore, early prevention and diagnosis of these conditions is of great importance. A number of psychometric tests have been proposed as cognitive screening tools. Given the fact that many of them show weaknesses and difficulties in performance, scientists have sought for more useful alternatives. Montreal Cognitive Assessment (MoCA) is considered to be a good choice, as it has been successfully applied in the perioperative setting. What's more, it has been translated and validated for a Greek population with neurological disorders. Addenbrooke's Congnitive Examination III (ACE III) has been introduced recently into clinical practice. It is an easy to perform and detailed test that covers several neurocognitive domains and has shown high sensitivity and specificity in clinical conditions, including dementia and Alzheimer's disease. Although current literature lacks data concerning its perioperative use, ACE III could prove useful for screening patients undergoing surgery and anesthesia on the basis of its favorable characteristics as mentioned above. The aim of this study is to translate the ACE III (English version 2012) into Greek and assess its validity in perioperative patients aged >55 years.
The objective of this single arm interventional study is to determine if renal denervation performed in the distal main and first order branch renal arteries is as effective in reducing blood pressure as the procedural approach used in the SPYRAL HTN-OFF MED clinical study.
The aim of this study is to collect the data on the effectiveness of dalbavancin in terms of save of hospitalization days on patients treated between June 2017 and June 2019 in two countries (Italy and Greece) vs the other Standards of care of the same class (SoC; i.v. lipo and glycopeptides) in a real-life context. Time to discharge from the start of therapy for ABSSSI in the hospital context will be assessed and all relevant data available on patient management, clinical, microbiological and safety outcomes during hospitalization and in the follow-up visits up to 30 days from discharge will be collected and evaluated.
A study to address the effects of early-day fasting on fat tissue mobilization in comparison to a typical isocaloric Mediterranean and a low-carbohydrate breakfast.
Plant derived foods contain large quantities of non-nutrient phytochemicals that have been extensively studied for their beneficial health effects on the prevention of chronic diseases. Although research on their health effects is abundant, our knowledge on absorption and bioavailability is yet narrow and in some cases zero. The concept of bioavailability involves the identification of the fraction of administered compounds that can reach plasma and body tissues in an unchanged form. The bioactivity of components in foods that are part of our nutrition, either as parent foods or as food supplements, is directly related to bioavailability, the latter being a necessary step to prove efficacy. Mastiha Oil (MO) is extracted from the resin of Pistacia Lentiscus var. Chia (of the Anacardiaceae family), a concentrated source of monoterpenes (e.g., α-pinene, β-pinene, β-myrcene) and triterpenes (e.g., mastihadienonic acid, isomastihadienonic acid), and to a lesser extent of plant sterols, simple phenols and approximately 10% MO (Assimopoulou, & Papageorgiou, 2005, Paraschos et al, 2007, Kaliora, Mylona, Chiou, Petsios, & Andrikopoulos, 2004). MO is a 100% natural product used as a food additive and flavoring and it is manufactured according to the legal standards that make it suitable for human consumption. Its nutritional analysis is presented in Supplementary Table 1. A total of 90 components have been detected in MO (50% monoterpene hydrocarbons, 20% oxygenated monoterpenes, 25% sesquiterpenes). Monoterpenes seem to exhibit beneficial health effects contributing to mechanisms of inflammation and oxidative stress (Subramaniyan, 2017; Madhuri, & Naik, 2017). Research upon the bioavailability of monoterpenes in humans is limited. Herein, we aimed at investigating the bioavailability of the main monoterpenes of MO in humans for the first time. To this end, a novel GC-MS-MS method was employed, since the tandem MS technique can help overcome matrix difficulties. Additionally, based on the existing data regarding the antioxidant activity of monoterpenes, the effect on human antioxidant capacity was evaluated applying the serum oxidisabilty assay. .
