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 present study aims to investigate whether the dosage of the GnRH agonist used for triggering final oocyte maturation affects the maturity of the oocytes retrieved in high risk for OHSS patients undergoing ovarian stimulation for IVF using GnRH antagonists and recombinant FSH.
The ALL SCTped 2012 FORUM is a multinational, multi-centre, controlled, prospective phase III study for the therapy and therapy optimisation for children and adolescents with ALL in complete morphological remission (CR, less than 5% bone marrow blasts, no blasts in cerebrospinal fluid, no other extramedullary leukemia), who have an indication for HSCT with a myeloablative conditioning regimen. The stratification of patients in first and following remissions according to the individual transplantation modalities rests upon an indication for allogeneic HSCT and the availability of a suitable donor within the individual transplantation groups.
- There is evidence that inflammatory processes may play detrimental role during the acute phase of myocardial infarction - The hypothesis of this study is that colchicine, by its anti-inflammatory action, may lead to reduction in infarct size, when administered during the acute phase of myocardial infarction
BACKGROUND: In industrialized countries a considerable and increasing proportion of strokes occur at younger ages. Stroke at young age causes marked disability at worst and thus long-standing socioeconomic consequences and exposes survivors for 4-fold risk of premature death compared with background population. Up to 50% of young patients with ischemic stroke remain without definitive etiology for their disease despite extensive modern diagnostic work-up (i.e. cryptogenic stroke). The group of cryptogenic strokes includes those with patent foramen ovale (PFO) or other abnormalities in the atrial septum in the heart as the only or concomitant finding. Population prevalence of PFO is high, 25%, and the mechanisms how PFO would be associated causally with ischemic stroke remain to be clarified. Moreover, there are only scarce data on clinical outcome, long-term risk of new vascular events, and prevention of such events in these patients. DESIGN: Searching for Explanations for Cryptogenic Stroke in the Young: Revealing the Etiology, Triggers, and Outcome (SECRETO) is an international prospective multicenter case-control study of young adults (age 18-49) presenting with an imaging-positive first-ever ischemic stroke of undetermined etiology (aim N=2000). Patients are included after standardized diagnostic procedures (brain MRI, imaging of intracranial and extracranial vessels, cardiac imaging, and screening for coagulopathies) and age- and sex-matched to healthy controls in a 1:1 fashion. Up to 45 study sites worldwide will be needed to recruit the planned participant population during a 3-year period. Neurovascular imaging and echocardiography studies, and ECGs will be read centrally. AIMS: SECRETO involves five principal fields of investigation: (1) Stroke triggers and clinical risk factors; (2) Long-term prognosis (new vascular events, functional and psychosocial outcomes); (3) Abnormalities of thrombosis and hemostasis; (4) Biomarkers of e.g. inflammation, atherogenesis, endothelial function, thrombosis, platelet activation, and hemodynamic stress to characterize postulated cryptogenic stroke mechanisms; and (5) genetic study, including genome-wide association and candidate gene studies as well as next-generation sequencing approach. All analyses consider cardiac functional and interatrial structural properties as a possible mediator. Furthermore, SECRETO Family Study (substudy) aims at collecting extensive family history of thrombotic events from informative patients being screened for SECRETO main study and collect genetic samples from all consenting family members for whole-genome sequencing. SIGNIFICANCE: SECRETO will provide novel information on clinical and subclinical risk factors, both transient and chronic, predisposing to cryptogenic ischemic stroke in young adults. This study also reveals long-term prognosis of this understudied patient population and may discover new genetic background underlying the disease mechanism and provide potential targets for drug development.
To delineate the effect of MSM on osteoarthritis
The Left interscalene block has a different effect on heart's autonomic nervous system, compared to Right interscalene block. This effect is evident on the occurrence of bradycardia and hypotension during shoulder surgery in the beach chair position
Total Knee Replacement can be performed under the combination of posterior lumbar plexus block plus sciatic nerve block. The investigators can have the same outcome by performing instead of posterior lumbar plexus block more peripheral nerve blocks. More specifically under the combination of sciatic nerve block plus femoral nerve block plus obturator nerve block.
The purpose of this study is to determine whether the combination with ramipril and clopidogrel leads to further improvement of endothelial function, reduction of oxidative stress and reduction of vascular inflammation, compared with ramipril monotherapy, in patients with Diabetes Mellitus type 2 and diabetic nephropathy.
The purpose of this study is to assess the efficacy of the hydrolocalization technique for placement of femoral perineural catheters in comparison with stimulating catheters. A non inferiority trial.
This is a randomized study of the European SIOP Neuroblastoma Group (SIOPEN) in high-risk neuroblastoma (stages 2, 3, 4 and 4s MYCN-amplified neuroblastoma, stage 4 MYCN non amplified > 12 months at diagnosis). The protocol consists of a rapid, dose intensive induction chemotherapy, peripheral blood stem cell harvest, attempted complete excision of the primary tumour, myeloablative therapy followed by peripheral blood stem cell rescue, radiotherapy to the site of the primary tumour and immunotherapy (R4 randomization - isotretinoin and ch14.18/CHO (Dinutuximab beta, Qarziba ®).), with or without s.c. aldesleukin (IL-2)). Patients diagnosed after the closure of R3 randomization will not be R4 randomized. For these patients the use of ch14.18/CHO antibody is recommended without scIL-2 as continuous infusion as standard of care outside of controlled trials. ch14.18/CHO received marketing authorization by EMA in May 2017 (Qarziba ®). In the induction phase, all patients receive Rapid COJEC following the result of the R3 randomization which was closed on June 8th, 2017 after inclusion of 630 patients as planned. Following induction treatment peripheral blood stem cell harvest (PBSCH) is performed and complete excision of the primary tumour will be attempted. Patients with an inadequate metastatic response to allow BuMel MAT followed by PBSCR at the end of induction should receive 2 TVD (Topotecan, Vincristine, Doxorubicin) cycles. After Rapid COJEC induction, localized patients will proceed to consolidation. Patients aged 12-18 months at diagnosis, with stage 4 neuroblastoma, no MYCN amplification and without segmental chromosomal alterations (SCAs) are thought to have a good prognosis and will stop treatment after induction therapy and surgery to the primary tumour. Consolidation consists of BuMel MAT based on the results of the R1 randomization followed by peripheral blood stem cell rescue (PBSCR) and radiotherapy to the site of the primary tumour. The R2 immunotherapy randomization using ch14.18/CHO as 8 hour infusion on 5 consecutive days ( total dose (100mg/m²) with or without aldesleukin (IL-2) alternated with isotretinoin (13-cis-RA) is closed. The amended R4 immunotherapy randomization using ch14.18/CHO as continuous infusion (total dose 100mg/m² over 10 days) with or without aldesleukin (IL-2) alternated with isotretinoin (13-cis-RA) has accrued according to plan with results pending awaiting data maturity and DMC approval.
