There are about 10004 clinical studies being (or have been) conducted in Brazil. 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.
An investigator initiated and conducted, multicentre, international, double-blinded, placebo-controlled, parallel-group, randomised controlled trial to determine the effect of more intensive blood pressure control provided by a fixed low-dose combination blood pressure lowering pill ("Triple Pill") strategy on top of standard of care, on time to first occurrence of recurrent stroke in patients with a history of stroke due to intracerebral haemorrhage.
Double-blind, randomized clinical trial to assess the effects of 1,55 g/day of n-3 fatty acids from fish oil concomitant chemotherapy in gastrointestinal cancer.
The main purpose of this study is to determine new diagnostic criteria for an eye disease called keratoconus.
This is a multi-center, long-term safety and efficacy follow-up study for participants with cerebral adrenoleukodystrophy (CALD) who have received Lenti-D Drug Product (eli-cel) in a parent clinical study. After completing a parent clinical study (approximately 2 years), eligible participants will be followed for an additional 13 years for a total of 15 years post-drug product infusion. No investigational drug product will be administered in this study.
The investigators will select 30 patients with symmetrical impaction of third molars, according to Pell and Gregory dental impaction classification, who would be submitted to two surgical procedures, right and left, and in both surgeries dexamethasone 8 mg was administered in the pre-surgery phase, and the use of dexamethasone (12 mg/day) for 3 days on one side and diclofenac sodium (150 mg/day) for 3 days on the other side was continued, in a randomized, double-blind and cross-over trial so that all patients acted as control of themselves (split-mouth). Other drugs used in postoperative period, rescue analgesic and antibiotic therapy will be identical for all patients. The analyzed variables will be the visual analogue pain scale (VAS), total number of consumed analgesics, swelling and trismus (objectively), which were statistically analyzed by means of Student's t-test.
This study is design to evaluate the effectiveness of oral iron therapy in patients with heart failure and identify the central and peripheral mechanisms involved in the improvement of functional capacity after intervention. The investigation includes subjective and objective measures on exercise performance and heart function after intervention, and the tolerability of oral iron treatment.
The purpose of this study was to confirm efficacy and safety of osilodrostat for the treatment of patients with Cushing's disease who are candidates for medical therapy.
The main purpose of this study is to evaluate the efficacy and safety of ixekizumab in tumor necrosis factor (TNF) inhibitor-experienced participants with radiographic axial spondyloarthritis (rad-axSpA).
Different anesthetic techniques have been proposed for carrying out Inguinal hernia repair, including local anesthesia, regional and general. There are no recent data on the application of a validated questionnaire to assess which anesthetic technique, local infiltration under general anesthesia or spinal anesthesia, would provide better quality of recovery in the opinion of the patients undergoing inguinal hernia repair. The aim of the study is to perform a randomized clinical trial comparing the quality of recovery (QoR-40) after local infiltration under general anesthesia via laryngeal mask (LMA) or spinal anesthesia for unilateral inguinal hernia repair. METHODS - Seventy patients aged 18 to 65 years old, who were scheduled to undergo unilateral inguinal hernia repair at Santa Lucinda Hospital will be enrolled in the study. The anesthesia will be performed according to the following sequence: L Group - intravenous (I.V.) propofol and alfentanyl, followed by LMA positioning. The anesthesia will be maintained by propofol. For local anesthesia, approximately 50 ml of 0.5% ropivacaine will be infiltrated along the line of incision in the subcutaneous plane, followed by peripheral nerve block technique (e.g., ilioinguinal-hypogastric nerve block) and local wound infiltration at the fascial level. S Group - spinal puncture followed by intrathecal 15 mg of 0.5% hyperbaric bupivacaine injection and sedation with propofol by continuous infusion. Pain will be assessed every 15 minutes at Post-anesthesia Care Unit (PACU) using a 0-10 numeric pain rating scale and I.V. morphine will be administered to maintain the pain score below 4. The QoR-40 will be administered by a blind investigator 24 hours after surgery.
This study evaluate the effectiveness of adding neuromuscular exercises with tactile, visual and auditory feedback to a scapula-focused treatment, both emphasizing the periscapular muscles on improvement of disability in patients with subacromial pain syndrome compared to patients receiving only strengthening exercise protocol.
