There are about 21071 clinical studies being (or have been) conducted in Spain. 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 aim of the study is to compare the effect of Roux-en Y reconstruction (study group, DPCDA) versus classical Child reconstruction (DPCUN) in the incidence of VGL in patients for DPC. The hypotesis of the study is that Roux-en Y reconstruction decreases incidence of DGE after pancreaticoduodenectomy.
The purpose of this study is to compare STZ vs everolimus as first line treatment for advanced pNET and to elucidate which sequence of streptozotocin (STZ) based chemotherapy and the mammalian Target of Rapamycin (mTOR) inhibitor, everolimus, gives better results in terms of second Progression Free Survival (PFS) in well differentiated and advanced pancreatic NETs.
Randomized clinical trial to assess the influence of treatment with ticagrelor or clopidogrel in the number of CECs (Circulating Endothelial Cells) and EPCs (Endothelial Progenitor Cells) in patients with ACS (Acute Coronary Syndrome), from baseline levels to chronic levels (1 month).
The aim of this study is to determine what is the best time interval between GnRH agonist (triptorelin acetate) ovulation induction allowing for the higher number of mature oocytes (MII) collected in IVF cycles.
The PET tracer Fluoro-ethyl-methyl-amino-naphthyl-ethylidene-malononitrile ([F18]-FDDNP) has a specific affinity for lesions containing tau protein and beta-amyloid The study consists of two phases - In a first transversal phase, 8 neurologically unimpaired controls, 15 patients with PD and no dementia (PDND) and 8 with PD and dementia (PDD) will undergo lumbar puncture for study of tau, phospho-tau and beta-amyloid levels in cerebrospinal fluid (CSF), as well as positron emission tomography (PET) with ([F18]-FDDNP. Concentration of CSF markers and both the degree and topography of FDDNP-PET uptake will be compared among groups, along with correlation analysis between CSF and PET findings. - During the second phase (18 months follow-up), the PDND patients will undergo the same procedures, and cognitive changes including incident dementia will be assessed. The correlation between cognitive impairment and neurochemical and neuroimaging changes will be established to determine the predictive value of these markers. Since the pathological lesions observed in Alzheimer disease (AD) are common in the PD and the concentrations of tau and beta-amyloid are altered in AD and PET with [F18]-FDDNP is able to separate patients with AD and cognitive impairment from controls, we hypothesized that: 1. - Patients with PD will show a biomarkers profile similar to the AD (decreased levels of beta-amyloid and increased phospho-tau and tau) in CSF, and an abnormal uptake of [F18]-FDDNP PET compared to PDND patients and controls. 2. -The distribution of cortical [F18]-FDDNP in the PD will be different from the AD and similar to dementia with Lewy bodies, predominantly in posterior cortical areas. 3. PDND patients will show a [F18]-FDDNP PET uptake and levels of protein markers in CSF intermediate between controls and patients with PD. 4. -In the subsequent follow-up, PDND patients will show cognitive impairment correlate to changes in the levels of protein markers in CSF and uptake of PET with [F18]-FDDNP 5. - The predictive value for the development of dementia in PD of specific patterns of PET uptake and CSF proteins profile will be established.
Phase I trial aimed to determine the Maximum Tolerable Dose of the BV in combination with ESHAP in relapsed/resistant Hodgkin Lymphona patients and to evaluate response to treatment with BV-ESHAP as salvage regimen prior to autologous stem cell transplantation.
This is a phase I clinical trial in healthy volunteers comparing the effect of lysine acetylsalicylate or aspirin on platelet function.
This study is a 12-month, dose-level blinded, multicenter study of 2 inhaled dose levels of CVT-301 for the treatment of up to 5 OFF episodes per day in PD patients experiencing motor fluctuations (OFF episodes). All patients will receive active treatment, but patients will be blinded to dose level. This will serve as an extension to the CVT-301-004 (NCT02240030) study for those patients who participated in that study and remain eligible for this study. In addition, patients who previously completed the CVT-301-003 (NCT01777555), CVT-301-009 (NCT02807675) and CVT-301-005 (NCT02352363) (observational arm completers), as well as CVT-301 naïve patients may be enrolled if they meet the CVT-301-004E eligibility criteria.
The purpose of this study is to narrow the gap between patients being diagnosed with severe aortic stenosis and those being appropriately monitored and treated. For this purpose a prospective survey of current practice (3 months) will be conducted followed by a six month period of intervention during which a variety of quality improvements measures will be implemented. There will then be a 3 month follow-up period during which the legacy of this initiative will be monitored during which no intervention will be carried out.
The analgesic properties of ketamine are associated with its non-competitive antagonism of the N-methyl-D-aspartate receptor; these receptors exhibit an excitatory function on pain transmission and this binding seems to inhibit or reverse the central sensitization of pain. In the literature, the value of this anesthetic for preemptive analgesia in the control of postoperative pain is uncertain. The objective of this study was to ascertain whether preoperative low-dose ketamine reduces postoperative pain and morphine consumption in adults undergoing colon surgery. In a double-blind, randomized trial, 48 patients were studied. Patients in the ketamine group received 0.5 mg/kg intravenous ketamine before surgical incision, while the control group received normal saline. The postoperative analgesia was achieved with a continuous infusion of morphine at 0.015 mg∙kgˉ¹∙hˉ¹ with the possibility of 0.02 mg/kg bolus every 10 min. Pain was assessed using the Visual Analog Scale (VAS), morphine consumption, and hemodynamic parameters at 0, 1, 2, 4, 8, 12, 16, and 24 hours postoperatively. We quantified times to rescue analgesic (Paracetamol), adverse effects and patient satisfaction.
