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.
The use of electrical stimulation to reduce urinary incontinence in men undergoing prostatectomy exercises of the pelvic floor muscles (MAPs)
The brachial plexus block is an anesthetic technique often used for surgical procedures of the upper limb. The brachial plexus block through the axilla (BPVA) is one of the techniques most commonly used to obtain regional anesthesia of the upper limbs, being performed by anesthesia of the terminal branches of the brachial plexus, which would be the ulnar, median, radial and musculocutaneous nerves. With the aid of ultrasound , two techniques can be used to perform the BPVA . The first , known as multiple puncture technique , the local anesthetic is deposited around each nerve that want to block . This technique is most commonly used to perform the BPVA . The second technique , known as 2 injections , local anesthetic is deposited below the axillary artery and around the musculocutaneous nerve . This technique has been proposed to try to reduce the execution time of anesthesia . Studies actually show that the technique of 2 injections showed less time to perform the block, with the same success rate. However, the technique of 2 injections showed a longer latency and higher rate of vascular puncture . (14) In order to perform a procedure with shorter execution time , without changing the latency, success rate and ensuring patient safety , the investigators designed this protocol to evaluate three techniques for performing the ultrasound- guided axillary brachial plexus block.
Introduction: Noninvasive ventilation (NIV) has been used to minimize such impairment and increasing ventilator reserve in individuals with heart failure. Aim: To analyze thoracoabdominal kinematics (TK) in individuals with HF associated to cardiomegaly after using NIV. Methods: A randomized crossover clinical trial with allocation consisted of two experimental phases: NIV and control, 7 days apart of each other. During NIV phase, 30 minutes of bi-level ventilation was performed. Any type of ventilator support was offered during control phase. Optoeletronic plethismography was performed to asses TK.
The investigators hypothesized that combined endocardial and epicardial VT ablation using contact sensor irrigated catheter is safe and achieves a lower recurrence rate than endocardial only ablation in ischemic and non-ischemic patients, for this the investigators will randomize 20 patients in two groups, one with endocardial only ablation and other with combined endocardial and epicardial ablation.
This study evaluates the hypothesis that a meal constituted of only glucose produces differences in the brain blood flow in people with obesity that are not observed in people without obesity. These changes, at least in part, could explain the mechanisms involved in maintenance or development of obesity.
Supervise dental conditions and teach the procedure of oral hygiene are the responsibility of the nurse. Patients on chemotherapy have risk for oral and systemic changes factors. The investigators will evaluate the cognitive and procedural knowledge about oral hygiene and the relevance of the learning experience importance.
The proposed study is to evaluate the possible effect of metformin on arterial pressure by 24h-ambulatory blood pressure monitory (24h-ABPM).
This is a multicenter, double-blind, Phase 2b, long-term extension (LTE) to the ADDRESS II core trial (EMR 700461-023) (NCT01972568), to evaluate long-term safety and tolerability of atacicept in participants with systemic lupus erythematosus (SLE). Participants who completed the 24-week core study ADDRESS II core study (NCT01972568) and thus not met any of the discontinuation criteria were invited to enter this long-term extension (LTE) study NCT02070978.
This is a multicenter, open label, randomized bioequivalence study of BEVZ92 (bevacizumab biosimilar) and Avastin® with 2 parallel arms to compare the pharmacokinetic (PK) profile of BEVZ92 and Avastin® in combination with FOLFOX (any) or FOLFIRI chemotherapy. FOLFOX (any) or FOLFIRI will be chosen as per investigator criteria based on the hospital standard of care.
One of the challenges in treating patients with heart failure (HF) is achieving clinical stability and reducing the hospital readmission rate. A diuretic dose adjustment algorithm developed in the United States (Diuretic Treatment Algorithm, DTA) and later validated for use in Brazil (as the Algoritmo de Ajuste de Diurético, AAD) has proved feasible and readily applicable, but its effect on clinical outcomes has yet to be assessed. This report aims to describe a randomized clinical trial protocol designed to assess the effectiveness of the AAD and of nonpharmacologic management in improving clinical stability and reducing the readmission rate at 90 days in patients with HF.
