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.
Approximately 5% of the world's adult population has some alcohol-related disorder, which in addition is associated with 3% of all deaths in the world. In Brazil, harmful use and dependence on alcohol reach about 10% of the population, with alcohol being one of the main factors of disease and mortality. Although the medications currently used have some efficacy, the adverse effects and relatively long time of treatment are factors that may reduce patients' motivation to continue taking the medication correctly. Therefore, it is necessary to conduct research with new drugs for the treatment of alcoholism. Ibogaine is an alkaloid present in the bush Tabernanthe iboga (iboga), a plant from Central Africa traditionally used in countries such as Gabon and Cameroon. Animal studies and case series suggest that one or a few doses of ibogaine significantly reduce withdrawal symptoms and the intensity of use of various drugs, including opioids, psychostimulants, and alcohol. However, there are no controlled clinical studies that have explored these effects. The aim of the present study is to evaluate the safety, tolerability and efficacy of increasing doses of ibogaine in 12 alcoholic patients. Each patient will be hospitalized for 20 days and receive 3 increasing doses of ibogaine. The first 3 patients will receive oral doses of 20 to 400 mg of ibogaine in an open-label design. If the 3 higher doses (240, 320 and 400 mg) are well tolerated, the next 9 volunteers will receive these doses or placebo randomly. The volunteers will also be evaluated 7, 14 and 21 days and 1, 3, 6 and 12 months after leaving the hospital to monitor the consumption of alcohol and other drugs.
The purpose of this study is to explore the antiviral effect of JNJ-53718678 at 2 dose levels (80 milligrams [mg] and 500 mg) once daily for 7 days in adults with Respiratory Syncytial Virus (RSV) infection, as measured by RSV viral load in nasal secretions by quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay.
This is a double-blind, randomized, double-dummy, comparative study in parallel groups of subjects presenting with recurrent cystitis (≥2 episodes within the past 6 months). Subjects will be randomized and treated with one of two presentations of urinary antiseptics containing methenamine and methylthioninium for three days, followed by three days of antibiotic therapy as determined by urine culture and antibiogram. This study aims to assess the efficacy and safety of each treatment.
Knee arthroplasty is performed with restriction of blood flow by use of the pressure tourniquet. Ischemia of skeletal musculature is accompanied by the formation of reactive oxygen species and release of vasoactive factors. Inhaled anesthetics were described as possible protective factors, termed "ischemic preconditioning". The objective of this investigation is to observe the effects of preconditioning with inhaled anesthetic on bleeding in the postoperative period of knee arthroplasty surgery. The study will be prospective and randomized. Patients will be allocated by means of a randomized table in two groups: Group Preconditioning (GP) - subarachnoid and general anesthesia with preconditioning with 1 minimal alveolar concentration (MAC) for 15 minutes before the installation of the ischemia by tourniquet; Group control (GC) - subarachnoid and general anesthesia with sevoflurane without preconditioning. Will be evaluated: hemoglobin and hematocrit, platelet count and coagulogram, electrolytes and creatinine, lactate and glycemia. Volume of drainage will be evaluated until drainage is withdrawn and need for transfusion measuring the number of bags of blood concentrate and volume transfused. Pain assessment will be done by means of visual analog scale. Morbidity will be recorded up to the 30th postoperative day by chart analysis. Patients will be allocated to the study groups by random number table. Data will be presented descriptively, frequently, mean and standard deviation, or medians and distribution in 25-75% percentiles. The comparison between continuous measurements will be made by means of repeated measures intra-group analysis of variance (ANOVA) and Student's t-test for evaluation between groups. The need for transfusion will be compared by Fisher's exact test. Pain intensity will be compared by Wilcoxon test for non-parametric data. A commercially available statistical package - SPSS version 15.0 (SPSS Inc.) will be used. A value of P <0.05 will be considered statistically significant.
Post-exercise hypotension (PEH) is a established phenomenon as one of the non-pharmacological ways of reducing blood pressure, producing important impacts, particularly in hypertensive individuals. However, the factors involved in the magnitude and duration of this effect are relatively little studied. Thus, the bioavailability of vasodilatation mediators may maximize the duration and magnitude of PEH. In this sense, the objective of the present project will be to verify the impact of L-citrulline associated with L-arginine supplementation on the acute blood pressure response after an aerobic exercise session. Approximately 80 adults (40 normotensive and 40 hypertensive) will be selected. The sample will be submitted to measurements of body mass, height and resting blood pressure. After the minimum interval of 48 h, subjects will be randomly submitted to four experimental situations (exercise/L-citrulline, exercise/L-arginine, exercise/placebo, exercise/L-citrulline + L-arginine). The exercise sessions (40 min in treadmill at 60% of FCres) will be performed with a minimum interval of 48 h. After each session, the blood pressure of the sample will be recorded during 24 hours. For data analysis, blood pressure values will be plotted in average of the wakefulness and average of the sleep periods and average of the 24 hours. The comparisons will be made through the ANOVA (repeated measures), following the recommended assumptions. It is hoped that the results of this project will collaborate to the knowledge regarding non-pharmacological models aimed at the prevention and treatment of hypertension in normotensive and hypertensive patients.
This study is a pragmatic open-label international randomized trial comparing therapeutic dose intravenous unfractionated heparin (UFH) to standard care venous thromboprophylaxis in patients diagnosed with septic shock.
A high degree of turnout is desired by many dancers, because enables an efficient weight transfer; provides an excellent extension and control; and reduces the risk of injury when used properly. The dancer's body conditioning is worked and acquired through various types of training, among which stands out the Pilates Method. Thus, the aim of the study is to determine the effect of a training program of Pilates Method in the range of ballerinas' turnout. The study will be conducted with young dancers, between 10 and 14 years, who practice classical dance twice a week. They will be randomly divided into two groups: intervention and control, but only the intervention group will do Pilates classes. To verify the extent of the turnout, tests will be applied in both groups, before the start of Pilates classes (pre-test) and after 24 sessions (post-test). In the evaluation protocol will be collected kinematic data, while performing the movements of demi plié and elevé. Anthropometric variables of height and body mass will be obtained; and also the extent of the passive and active turnout in dancers.
To evaluate the surgical repercussions in patients with traumatic brachial plexus injury in the respiratory and motor systems, trunk biomechanics, functional capacity and quality of life.
The investigators are doing this study to see the effect of insulin degludec in pregnant women with type 1 diabetes, and if it is safe to use. In this study the medicine insulin degludec is compared to another medicine called insulin detemir. Participants will either get insulin degludec or insulin detemir and take it together with a medicine called insulin aspart - which treatment participants get is decided by chance. Participants will get pre-filled insulin pens. Participants will need to take blood sugar measurements several times a day. The study will last between 10 and 25 months depending on whether participants are already pregnant when they join the study. The number of visits and the tests ( for example blood and urine samples and ultrasound scans) the participants will have also depends on whether they are pregnant at study start.
The aim of this study is to investigate engagement, motivation, and the barriers to adherence of virtual reality based therapy (VRBT) in patients with cardiac diseases and risk factors to the development of cardiac diseases. In addition, to investigate autonomic and hemodynamic responses of VRBT in comparison with conventional therapy (CT). To do this, patients with cardiac diseases or risk factors will be invited to perform CT or VRBT+CT. They will be submitted to an initial evaluation, and then will be random allocated to 12 weeks of intervention and to a final evaluation. The primary outcomes includes engagement, motivation, barriers and adherence in the 12 previous weeks using questionnaire, after 12 weeks of the intervention and after 12 weeks of the final intervention program. Hemodynamic and autonomic responses will be considered the secondary outcomes being evaluated before, during and after a session at the first, sixth and twelfth week.
