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 objective of this work is the development and validation (reliability and validity) of the Automatic image analyzer to assess it retinal vessel caliber (ALTAIR) platform to analyze and validate its utility in different clinical settings. Methods / Design Design : In the first phase , will be a cross- sectional study and a second phase will be a prospective observational study with annual follow-up for 4 years. The study will be conducted in primary care including 386 subjects. Main measurements: blood pressure, carotid intima-media thickness using carotid ultrasound , central blood pressure and wave velocity pulse by SphygmoCor system, Cardio-ankle vascular index (CAVI) by VASERA® VS1500 , evaluation of hypertrophy ventricular using a digital ECG and renal injury . Retinal vascular evaluation will be done by a non-mydriatic TOPCON TRCNW200 getting focused papilla, nasal and temporal and developed by software images automatically calculate the thickness of the retinal vessels , the arteriovenous index, the vascularized area and branching pattern . For validation software retina intra and inter - observer variability , the correlation of the tool measurement with AVindex , and concurrent validity with parameters of vascular structure and function and target organ damage and association analysis will analyze the different parameters of the estimated retina and evolution or appearance of new lesions in the target organs. Discussion The validation of the tool contribute to the analysis of retinal vessels improved reliability by reducing the intervention of the observer and further validate the use of more information than the previously used , especially surface vascularization and vessel branching patterns .
The purpose of this study is to gather information about the steady-state plasma concentrations of aripiprazole, olanzapine, quetiapine and their relevant metabolites, at various dose levels and at different time points after dosing. In addition, comparison of capillary drug concentrations vs. venous drug concentrations will be performed for aripiprazole, olanzapine, paliperidone, quetiapine, risperidone and their relevant metabolites.
The study objective is to evaluate the efficacy and safety of trazodone OAD vs venlafaxine extended release (venlafaxine XR) after an 8-week treatment period in patients with major depressive disorder.
Cross-sectional study, observation made by healthcare professionals of subjects or caregivers, administering romiplostim at their first standard-of-care visit 4 weeks after training with the home administration training pack. Further observations can also be recorded in the study if made within 16 weeks of enrolment. Data will be collected from the subjects' dose diary at their first standard of care visit to ensure there were no problems with administration while not at the clinic.
Lateral epicondylitis (LE) is the most common cause of lateral elbow pain. Intratissue percutaneous electrolysis (EPI technique) is a novel minimally invasive approach which consists in the application of a galvanic current through a puncture needle which produces a local inflammatory process in the soft tissue and the reparation of the affected tissue. The purpose of this study is to evaluate the clinical and ultrasonographic effectiveness of a multimodal program using the intratissue percutaneous electrolysis technique and exercises in the short term for patients with chronic lateral epicondylitis, and to determine whether the clinical outcomes achieved decline over time. This study is an observational one-way repeated measures design. 36 patients in a clinical setting presenting with lateral epicondylitis (mean age = 38, mean time since injury = 12.6 months) received one session of EPI per week over 4-6 weeks, associated with a home program of eccentric exercise and stretching. The main outcome measures were severity of pain (VAS, digital algometer, Cozen and Thompson tests), disability (DASH questionnaire), structural tendon changes (ultrasound), hypervascularity (power doppler) and patient's perceptions of overall outcome (4-point scale). Measurements at 6, 26 and 52 weeks follow-up included recurrence rates (increase of severity of pain or disability compared to discharge), the perception of overall outcome and success rates. Paired Student t-tests and Chi squared tests were applied to data. Enrollment into this study ended in September 2012. All outcome measures registered significant improvements between pre-intervention and discharge. Most patients (30, i.e. 83.3%) rated overall outcome as 'successful' at 6 weeks. The ultrasonographic finding revealed that the hypoechoic regions and hypervascularity of the extensor carpi radialis brevis change significantly. At 26 and 52 weeks, all participants (32) perceived a 'successful' outcome. Recurrence rates were null after discharge, and at the 6, 26 and 52 week follow-ups.
Post-authorisation observational study to assess the evolution in normal clinical practice of patients recently diagnosed with myelodysplastic syndrome (MDS) or chronic myelomonocytic leukaemia (CMML), depending on the moment when active treatment is initiated. Subjects will be recruited from approximately 50 haematology sites in Spain.
Dose escalation phase of the study : To define the safety profile, maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of regorafenib administered orally as a single agent in a 3-weeks-on/1- week-off schedule in repeating cycles of 28 days in pediatric subjects with solid malignant tumors recurrent or refractory to standard therapy. To characterize the pharmacokinetics (PK) of regorafenib The dose escalation phase of the study has been completed. Expansion phase: To define the safety profile, MTD and the RP2D of regorafenib administered orally in combination with backbone chemotherapy (vincristine and irinotecan) at relapse in pediatric subjects with rhabdomyosarcoma (RMS) and other solid malignant tumors recurrent or refractory to standard therapy.
This is a Phase 2, open-label, randomized, 3-arm trial investigating the efficacy of two Sym004 doses (Arm A and Arm B) compared with a control group (Arm C) in subjects with metastatic colorectal cancer (mCRC) and acquired resistance to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs).
Circulating progenitor cells (CPC) treatments may have great potential for the recovery of neurons and brain function. Our group has reported how exposure to intermittent hypobaric hypoxia with superficial muscle electrostimulation is able to increase the concentration of CPC in peripheral blood in humans. Therefore, we believe that through physical activities and exposure to intermittent hypobaric hypoxia for a period, it will increase CPC in the blood of subjects who have suffered a severe Traumatic Brain Injury (TBI) one or more years ago, promoting regeneration and functional and cognitive recovery. The study primary end-point is to improve physical or psychological functioning of participants with TBI with a program of exercise, muscle electro-stimulation (ME) and/or intermittent-hypobaric-hypoxia (IHH). Secondary end-points are to increase and maintain CPC and also to study their possible relationship with physical or psychological improvement of participants with Traumatic Brain Injury (TBI). In order to achieve these objectives investigators have designed a randomized controlled trial that will include those patients who suffered severe TBI more than one year previously with physical or psychological sequelae. Exercise, muscle electro-stimulation (ME) and/or intermittent hypobaric hypoxia (IHH) programs will be applied during twelve weeks. Psychological and physical stress tests will carry out before and after the program and CPC will measure at the beginning, every two weeks, and at the end of the program.
Ultra-high density mapping with multielectrode catheter may improve slow conduction channels identification in ventricular tachycardia substrate ablation procedures compared to conventional point by point mapping. This study compares the ability of both mapping catheters to detect slow conduction channels in areas of myocardial scar and their utility to assess substrate modification after ablation.
