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.
Introduction: When babies are born prematurely, they are deprived of their usual space limits (uterus walls). This along with the action of gravity to which they are exposed after birth, makes the neonates have a low muscle tone, acquire a posture of extension, being more irritable and having difficulties with their alertness-sleep cycle. There are few studies that have assessed the effectiveness of positioning of premature neonates. However, none of these studies has focused on exploring the effects of positioning on the patterns of movement and gross motor function of the pre-term neonates. Aim: The aim of this study is to investigate the effects of positioning on the patterns of movement, gross motor development and physiological clinical outcomes of pre-term neonates. Methods: A sample of pre-term neonates of ≤ 32 weeks of gestation from the Neonatal Intensive Care Unit (NICU) of the General University Hospital of Patras will be randomly assigned to two groups. The intervention group will receive positioning with Snuggle up (Philips, USA), while the control group will receive usual care. Outcomes will be assessed with the general movements of Prechtl and the Denver II scale at baseline and at term-age of each neonate. Physiological outcomes will be also assessed such as heart rate, respiratory rate, weight gained from baseline to term-age, days to achieve full oral feeding, days on the ventilator, days on oxygen, and duration of stay in the NICU. Basic characteristics of the neonates will be obtained from their medical record, i.e. weeks of gestation at birth, gender, type of birth (normal or Caesarian), weight at birth, and Αpgar score and will be used to compare the 2 groups for similarities at the baseline of the trial.
The main goal is to determine the optimum dose of ropivacaine, a local anaesthetic, that provides regional anaesthesia with no or minimum adverse effects (i.e. hypotension) when given spinally in healthy full term tall parturients scheduled to undergo caesarean section under combined spinal / epidural anaesthesia (CSEA). The participants' height threshold is based on a local anthropometric research, which included over 2000 people. According to the above research the investigators calculated the female height distribution and decided to include in the study those distributed in the upper quartile (75th to 99th percentile). The female height distribution of the upper quartile ranges from 167 to 184 cm. Secondary objectives are adverse effects related to the anaesthetic technique (hypotension, discomfort, nausea, vomiting and pruritus), the speed of installation and the duration of the regional block (both sensory and motor), blood gas analysis of the newborn umbilical blood as well as newborn Apgar score and lastly the mothers' degree of satisfaction. This is a prospective non randomized double-blinded trial in which a specific algorithm for the local anaesthetic dose will be adopted (up-down sequential allocation). A written informed consent will be required by all participants. The perioperative management of all participants will follow standard clinical protocols. The dose of ropivacaine for each parturient is determined by the response of the previous participant to a higher or lower dose according to the sequential distribution algorithm (up-down sequential allocation). Specifically, the dose of ropivacaine for each parturient (except for the first) will fluctuate by 0.375 mg depending on the success (decrease by 0.375 mg) or failure (increase by 0.375 mg) of the spinal anaesthesia of the previous parturient enrolled in the study. The local anaesthetic dose of the first participant will be determined by a short pilot study.
This study will collect information on side effects and how well Refixia/REBINYN works during long-term treatment (prophylaxis) in males with haemophilia B. While taking part in this study, participants will receive the same treatment as given to them by their study doctor. All visits at the clinic are done in the same way as the participants are used to. During visits at the clinic, participants might be asked for some relevant tests if considered useful by their study doctor. During the visits, the participants study doctor might ask if the participants had any side effects since their last study visit. The participants will be asked to note down the number of bleeds and the treatment of their bleeds as well as their regular prophylaxis. During the visits to the clinic, the participants will be asked to answer some questionnaires about their quality of life and their ability to be physically active. The participant's participation in the study will last for 4-9 years, depending on when they join the study. Participants are free to leave the study at any time and for any reason. This will not affect their current and future medical care.
Study ROR-PH-303, ADVANCE EXTENSION, is an open-label extension (OLE) study for participants with WHO Group 1 PAH who have participated in another Phase 2 or Phase 3 study of ralinepag.
The objective of this study is to assess the efficacy and safety of upadacitinib combined with topical corticosteroids (TCS) for the treatment of adolescent and adult participants with moderate to severe atopic dermatitis (AD) who are candidates for systemic therapy.
The DERIVATE study was conceived to integrate the information resulted from clinical data, transthoracic echocardiography, and cardiac magnetic resonance (CMR) imaging to provide a more reliable risk stratification in patients affected by heart failure (HF) and worthy of prophylactic implanted cardioverter defibrillator (ICD) therapy. The main purposes of this multicenter registry are to: 1) determine CMR findings, and specifically late gadolinium enhancement (LGE) features, T1 mapping, and extracellular volume (ECV) that predict sudden cardiac death (SCD) and ventricular arrhythmia; 2) provide a comprehensive clinical and imaging score that effectively improves the selection of patients who deserve a prophylactic ICD therapy; 3) evaluate the contribution of machine learning to predict major adverse cardiac events (MACE) as compared to standard clinical scores.
Results from a small number of human cohort studies are also available and indicate that there are positive associations between organic food consumption and reduced risk/incidence of certain acute diseases (e.g. pre-eclampsia, hypospadias) and obesity/overweight. Results from animal dietary intervention studies suggest that (i) switching to organic food consumption results in significant changes in hormonal balances and an increase in immune system responsiveness and (ii) differences in pesticide residue, cadmium, protein and antioxidant concentrations between organic and conventional foods are major drivers for hormonal balances and immune system parameters in animals. However, there is virtually no published data from (i) long-term cohort studies focusing on chronic diseases (e.g. cardiovascular disease, diabetes, cancer and neurodegenerative conditions) and (ii) controlled human dietary intervention studies comparing effects of organic and conventional diets. It is therefore currently not possible to assess whether and estimate to what extent organic food consumption may affect human health.
The aim of the proposed study is to identify predictors of covert atrial fibrillation (AF) in Embolic Stroke of Undetermined Source (ESUS) patients and develop a prognostic score for the identification of covert AF in this population.
The present study aims to assess the effectiveness of three different retention schemes used to maintain tooth position after orthodontic treatment with fixed orthodontic appliances (stability) and to evaluate possible association between retention scheme and gingival recessions on the lingual surfaces of the lower anterior teeth seen for up to 5 years post-treatment. Moreover the possible association between primary relapse tendency and long term occlusal stability will be evaluated.
The EuroSIDA study is a prospective observational cohort study of 23,000+ patients followed in 100+ clinics in 35 European countries, Israel and Argentina. The study is the largest pan-European cohort study and few studies of a comparable design are available on a global scale. The EuroSIDA study is an ongoing collaboration and patients have been enrolled into the study through 11 cohorts since 1994. The main objective of the study remains the same as in 1994: to prospectively study, clinical, therapeutic, demographic, virological and laboratory data from HIV-1 positive persons across Europe in order to determine their long-term virological, immunological and clinical outcomes. Historically, EuroSIDA has been crucial in reporting key changes in the HIV epidemic, such as the dramatic changes in morbidity and mortality when combination anti-retroviral therapy (cART) was first introduced. As new anti-HCV treatment is introduced to HIV/HCV co-infected patients, it is important for EuroSIDA to remain in the forefront of investigating the treatment benefits and adverse effects. All study documents, study status, newsletters, scientific publications and presentations are available online and are updated continuously at project website. In general terms, the objective of the EuroSIDA study is to continue a long-term, prospective collection of clinical, laboratory and therapeutic data as well as plasma on a large cohort of consecutive HIV infected patients from across Europe in order to (1) assess the factors associated with the clinical, immunological and virological course of HIV infection and HIV-related co-infections and co-morbidities, and (2) continue to provide and develop a surveillance system to describe temporal changes and regional differences in the clinical course of HIV and HIV-related co-infections and co-morbidities in Europe.
