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.
Chagas disease is endemic to Latin America, and is of emerging importance in non-endemic countries because migration of people infected with T. cruzi. Current methods for diagnosis of T. cruzi infection are not ideal. Existing drugs for treatment are very limited, produce severe side-effects, and their effectiveness cannot be properly evaluated. Reliable biomarkers for prognosis, early diagnosis and effectiveness of treatment will be investigated.
The purpose of this study is to test the safety and effectiveness of the Medtronic CapSureFix Novus Model 5076 lead when patients are implanted with the Medtronic Advisa MRI pacemaker and undergo an MRI scan.
The purpose of this study was to assess whether pinitol improves hidrocarbonated metabolism parameters, and evaluate its effect on oxidative stress and endothelial function in diabetic, impaired and normal fasting glucose subjects. This was a 3-month randomised, controlled-placebo, parallel trial with a three-arm design. Patients were divided into three groups: diabetic (n=40), impaired fasting glucose (n=40) or normal fasting glucose subjects (n=40), receiving 4 g/day of pinitol/placebo.
Physical therapists have traditionally included various forms of manual therapy among the therapeutic approaches to spinal pathologies. The aim of this study was to evaluate the effect of diaphragmatic stretching on spine and thoracic movement in healthy adults.
This is a Phase II, randomized, double-blind, placebo-controlled study designed to assess the safety and clinical activity of multiple intravenous doses of MCMV5322A/MCMV3068A in cytomegalovirus (CMV)-seronegative recipients of a renal transplant from a CMV-seropositive donor, with use of a preemptive approach for prevention of CMV disease. Participants will be randomized into two treatment groups: active or placebo control; both arms will be followed preemptively. The study has a planned enrollment of approximately 120 participants (60 active and 60 placebo).
To investigate the biocompatibility of the peritoneal dialysis (PD) solution balance in comparison to the conventional PD solution in APD(automated peritoneal dialysis) patients using the APD cycler sleep•safe.
Primary objectives: The efficacy of the therapeutic decision taken by respiratory polygraphy (RP) against polysomnography (PSG) using the Epworth scale; Secondary Objective: 1. the cost-effectiveness of diagnosis and therapeutic decision valued using the Epworth Scale and EuroQol 5D. 2. effectiveness of the therapeutic decision by means of: 1) quality of life tests, 2) adherence and compliance to treatment, 3) blood pressure MAP, 4) biochemistry determinations. Design: prospective, randomized, controlled, open, parallel of non-inferiority. 440 patients will be randomized to diagnose and follow treatment based on the RP or the PSG. The follow-up will last 6 months with 4 assessments. Statistical analysis: We will compare the change in the Epworth scale between both arms of treatment through analysis of covariance. The premise of non-inferiority is -2 at the lower limit of 95% IC. Secondary variables will be analyzed using differences in independent means (or non-parametric equivalent) or Chi2 for dichotomous variables. Cost-effectiveness: costs generated by one and another method will be evaluated against the effectiveness of the primary variable using Bayesian techniques
The purpose of this trial is to investigate the efficacy and safety of lidocaine 5% medicated plaster in localized chronic post-operative neuropathic pain in comparison to placebo plaster.
To evaluate the safety and tolerability of multiple doses of BI 655064 administered subcutaneously in healthy volunteers (HVs) and in rheumatoid arthritis (RA) patients. To explore the pharmacokinetic (PK) and pharmacodynamic (PD) parameters of multiple doses of BI 655064 in healthy volunteers (HVs) and rheumatoid arthritis (RA) patients. To assess clinical effect of BI 655064 in RA patients with prior inadequate response to methotrexate (MTX) after 12 weeks of treatment
Background: In patients with cirrhosis on secondary prevention of variceal rebleeding with non-selective beta-blockers (NSBBs), the risk of rebleeding and death is markedly higher in those failing to achieve a good hemodynamic response (HVPG reduction ≥20% of baseline values or ≤12mmHg). However a substantial proportion of non-responders will never rebleed, thus appearing protected by NSBBs although non-detected by HVPG response. This low sensitivity hampers risk stratification and diminishes the cost-effectiveness of assessing the hemodynamic response to NSBBs. This is particularly relevant in prevention of rebleeding since in this scenario the risk of rebleeding and of other portal hypertension related complications is very high, which calls for early institution of effective therapy. Baseline HVPG bears prognostic significance with regards to risk of developing varices, decompensation, hepatocellular carcinoma and death1,2,7,8,18-27. However, no studies have investigated whether adding data from baseline HVPG may improve the sensitivity of the criteria defining a good or poor hemodynamic response. Hypothesis: Adding data from baseline HVPG may improve the sensitivity of the criteria defining a good or poor hemodynamic response. Objective: Exploring the prognostic value of basal HVPG that better discriminate those non-responders who do not re-bleed under prophylactic treatment with NSBBs. Methods: Observational cohort study. Training set: patients from two longitudinal studies conducted at the Hepatic Hemodynamic laboratory of the Hospital Clínic of Barcelona to assess the prognostic value of HVPG changes during continuous therapy with NSBBs for preventing variceal rebleeding. Validation set for chronic hemodynamic response: patients from two longitudinal studies conducted at the Hepatic Hemodynamic laboratory of the Hospital de Sant Pau of Barcelona to assess the prognostic value of HVPG changes during continuous therapy with NSBBs for preventing variceal rebleeding; a third cohort composed of patients undergoing acute hemodynamic response to intravenous propranolol will be studied. All patients received a preplanned follow-up in the outpatient clinic at 1, 3, and 6 months, and every 6 months thereafter in the original studies. End-point: bleeding from portal hypertensive sources (esophago-gastric varices or portal hypertensive gastropathy) (defined according to Baveno criteria 32), death or liver transplantation. Ethical aspects: All patients have given their written informed consent to use their data in the original studies.
