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.
A randomized prospective study in the evaluation of the long acting GnRH antagonist Degarelix against the classical multidose regime with Ganirelix for LH suppression during the follicular phase of an ovarian stimulation cycle in oocyte donors.
Major surgery can lead to postoperative disturbances in sleep patterns with subjective deterioration of sleep quality according to patients' reports as well as objective alterations of sleep architecture, as recorded by polysomnography Factors implicated in postoperative sleep disturbances include but are not limited to the severity of the surgical procedure, the neuroendocrine response to surgery, inadequate treatment of postoperative pain and external factors interfering with sleep, such as light, noise and therapeutic procedures There are no adequate data from current literature as to whether regional anesthesia is superior to general anesthesia regarding postoperative sleep quality in patients subjected to either mode of anesthesia. So, the aim of this study will be to assess the effect of two different anesthetic techniques (general versus regional) in patients subjected to similar operations Patients will be assessed with the Pittsburgh Sleep Quality Questionnaire (PSQI), regarding preoperative and long term postoperative sleep quality and sleep diaries regarding early postoperative sleep quality
Athletic training aims to increase and improve physical performance that is achieved through training overload combined with periods of rest and recovery. Overtraining syndrome (OTS) is associated with an imbalance between training and recovery. The symptoms associated with OTS vary between individuals and may reflect parasympathetic and/or sympathetic nervous system alterations as well as endocrine irregularities. The prevalence is not known, but it is usually reported among endurance athletes, such as cyclists, distance runners and triathletes. It appears that OTS represents a systemic inflammatory process with diffuse effects on the neurohormonal axis affecting host immunology and mood. Previous works, showed that cell-free DNA (cf-DNA) is correlated with the severity of excessive exercise-induced inflammation as well as with trauma and stroke severity suggesting that it might be used as a potential clinical marker for athletes with overtraining syndrome. Oxidative stress indices can be determined non-invasively and may reflect inflammatory responses after training suggesting that they could be used as clinical markers for the diagnosis of OTS. However, there are no available biomarkers to aid towards the diagnosis and/or prevention of OTS, except that of the persistence of unexplained underperformance despite an extensive recovery of the athlete. Therefore, the purpose of this study is to evaluate the potential of cf-DNA and selected oxidative stress variables as diagnostic biomarkers of OTS.
This is a Phase III, randomized, placebo-controlled, double-blind, multi-center study assessing the efficacy and safety of durvalumab with SoC SBRT versus placebo with SoC SBRT in patients with unresected clinical Stage I/II lymph node-negative (T1 to T3N0M0) NSCLC. An additional cohort will assess Osimertinib following SBRT in patients with early stage unresected T1 to T3N0M0 NSCLC harbouring an EGFR mutation.
Damage in vasculitis, as well as in other chronic inflammatory disorders, accrues over time resulting in impairment of quality of life, development of disability and increased mortality. For these reasons, damage represents an important outcome to be assessed and measured both in trials and clinical practice. Currently, the most widely used assessment tool for damage in vasculitis is the Vasculitis Damage Index (VDI). However, VDI was developed for a no specific type of vasculitis and it appears to be more suitable for damage assessment in ANCA-associated vasculitis than in Behçet' disease (BD). BD is a chronic and multisystem inflammatory disorder classified among vasculitides. As well as in other vasculitides, disease activity and treatment in BD can result in the development and accumulation of irreversible organ damage, such as blindness, tissue loss and a wide range of neurologic disorders. Recently the OMERACT has defined the Core Set domain of Outcome Measures for BD. Despite damage is included in the OMERACT outcome core set for rheumatic disease, a specific assessment tool for BD is currently not available. The aim of this study is to develop and validate the first tool for describing and measuring organ damage in patients with Behçet Disease (Behçet's disease Overall Damage index - BODI).
Through this study the investigators aim to clarify the relationship between trans-diaphragmatic pressure and various parameters of the diaphragmatic contraction evaluated by ultrasound. Moreover, a lung ultrasound exam will be performed at the end of spontaneous breathing, resistive breathing and maximal inspiratory pressure maneuver (MIP) in order to assess with the use of B-lines for extravascular lung water (EVLW). The following parameters will be studied: esophageal pressure, gastric pressure, diaphragm thickness at peak inspiration (Tdi,pi), diaphragm thickness at end expiration (Tdi,ee), diaphragm thickening (Tdi,pi - Tdi,ee), diaphragm thickness fraction [TFdi=(Tdi,pi - Tdi,ee)/Tdi,ee], diaphragm excursion (Dec), Maximal Inspiratory pressure (M.I.P), Pressure-Time product of the esophageal pressure (PΤPes),Tension Time Diaphragm Index (T.T.Di) and the rapid shallow breathing index (R.S.B.I.). These measurements will be made in two phases.Firstly, during the spontaneous breathing trial and secondly during spontaneous breathing through an airway of reduced diameter.Furthermore, during the M.I.P. test the aforementioned ultrasound parameters will be measured. The aim of this study is to discover new means of a successful prediction of weaning in the first 48 hours following extubation.
Postoperative headache is a major issue after general anaesthesia and surgery. The aim of this study is to investigate the possible difference in the occurrence of postoperative headache when general anaesthesia is maintained with propofol, which is supposed to have protective effects on migraine patients, versus sevoflurane.
Exploiting recent methodological advancements, several neuroimaging studies suggested that multisensory integration emerges from a dynamic interplay of distributed regions operating in large-scale networks. Nonetheless, the cortical structures and neuronal networks underlying the development of multisensory perception and plasticity, throughout the life span, have not yet been studied in detail. A special case of multisensory training is musical training, which utilizes stimulus' structural complexity, as well as the emotional drive that music is generating to the subjects, in order to induce augmented neuroplastic effects. Retaining the extensive neuroplastic characteristics of music training, MUSICPLAST will develop, investigate and deliver a computer provided multisensory training protocol that aims to induce neuroplastic changes in frontotemporal cortical areas. More specifically, the goal of the proposed project is threefold: (a) The in-depth understanding and modeling of the developmental trajectory of the cortical networks underlying multisensory perception, (b) the modeling of the developmental trajectory of the cortical networks underlying multisensory plasticity throughout the life span of healthy subjects; and (c) the translation of this model in a computer provided multisensory training intervention protocol, which will cause beneficial neuroplastic changes in pathological populations. Electroencephalographic, behavioral and neuropsychological measurements, and advanced data analysis procedures, pre- and post the training application are going to be employed in order to evaluate the resulting neuroplasticity holistically. The proposed protocol will also be translated into an applied intervention for 2 groups of pathological population, for which there are strong evidence that a multisensory cognitive training based on music may provide beneficial neuroplastic changes: elderlies suffering from mild cognitive Impairment and adolescents with dyslexia. The project is performed in the Laboratory of Medical Physics of the Aristotle University of Thessaloniki. It takes advantage of the extensive background of the laboratory in music and neuroscience, in multisensory perception and in applications that translate basic neuroscientific knowledge into computer based interventions for young adults and elderlies, building up a solid neuroscientific ground on which multidisciplinary characteristics of the project stand.
Postoperative care of high risk patients in the Intensive Care Unit (ICU) has for long been considered to be the gold standard of care in terms of reducing perioperative mortality.New evidence from a 7-day cohort study involving 27 countries comes to question this practice. The primary objective of our study is to detect any benefit of postoperative ICU care after elective surgery in terms of patient's outcome, length of hospital stay, complications and cost.
Transient hypocalcaemia consist the most common postoperative complication after thyroidectomy (10-45%). It may be mild and subclinical or cause mild or severe symptoms and may lead to longer hospital stay as well as in discomfort of the patients. For the management oral or intravenous calcium with or without vitamin D administration can be used based on the blood calcium levels and on the symptomatology. The investigators intent to study a new protocol with oral calcium and vitamin D given systematically from the day of operation to assess if this practice can minimize the rate of transient hypocalcaemia and as a consequence minimize the length of stay in the hospital.
