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 spinal cord injury is identified as the major cause of permanent disability worldwide, with the loss of ability to walk being the largest and most devastating of them for these patients. Our goal is to analyze the effects of electrical transcranial direct-current stimulation (tDCS) combined with gait training with partial body weight support aided by robotic device (Lokomat, Hocoma) in the gait of patients with incomplete spinal cord injury (SCI). In this stratified randomized double-blind study, the participants will be randomly allocated into one of both groups, outpatients (GA) or inpatients (GI), and will receive active or placebo tDCS followed by gait training with Lokomat (GA: 3 sessions/week x 10 weeks = 30 sessions; GI: 5 sessions/week x 6 weeks = 30 sessions). The functional assessments (through clinical and functional scales, assess gait, muscle strength, spasticity, balance and pain) and neurophysiological (cortical excitability measured by transcranial magnetic stimulation, electroencephalography and functional near-infrared spectroscopy) will be held before and after the training period. The functional assessments will be also held after 15 sessions (intermediate) and after 3 months follow up. The expected result is that patients that received the active tDCS presents an improvement over the ground gait after the Lokomat training period significantly greater than the placebo group, with relations between neurophysiologic, kinematics and functional measurements.
The primary purpose of the study is to quantify participants' demographic parameters, country standard therapies, treatment patterns and outcomes among participants with chronic lymphocytic leukemia (CLL), multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL) in oncology concentration hospitals in Latin America.
A crossover trial with healthy volunteers will be conducted. Six sessions will be performed once a week in a counterbalanced order and at least with seven days washout period to minimize carry-over effects. In each session, volunteers will be submitted to: fatigue and attention levels evaluation, cortical brain activity measures through paired pulse transcranial magnetic stimulation (pp-TMS), handwriting test, non-invasive cerebellar stimulation during serial reaction time task (SRTT) and performance perception evaluation.
This study evaluates the safety and efficacy of lefamulin, a pleuromutilin, for the treatment of adults with moderate to severe community-acquired bacterial pneumonia.
Brazil ranks 17th among the 22 countries responsible for 80% of tuberculosis (TB) cases in the world. In 2010, the number of new cases of tuberculosis in Brazil was 71,930 and in 4972 RS. In 2010, Brazil had a disease incidence of 37.6 / 100,000 in 2011 fell to 36.0 / 100,000. The Rio Grande do Sul(RS)S showed an incidence rate of 46.1 / 100,000 in 2011. The mortality rate was 2.4 / 100,000 population per year in Brazil and RS. In Porto Alegre, the incidence rate of all clinical forms of tuberculosis has remained, in the last six years, around 100/100.000 inhabitants per year, while the coefficient of pulmonary tuberculosis remained on average 50/100.000 inhabitants to year. Thus, Porto Alegre holds the 2nd place in Brazil among the capitals with the highest incidence of TB, classifying the city as high risk 5th. Porto Alegre also has a co-infection TB / HIV from 35.3% one of the highest in the country. The best strategy to prevent new cases of tuberculosis is to invest in early diagnosis and effective treatment of existing cases of the disease. As the treatment of the disease requires daily use of medications for an extended period of time (at least 6 months), adherence becomes the main determinant of the rate of healing of disease. There are several factors that contribute to poor adherence and treatment dropout: alcoholism, illicit drug use, infection with human immunodeficiency virus (HIV Human Immunodeficiency Virus), low education, unemployment, poor housing and prolonged the treatment. The irregular treatment and neglect are the major obstacles to the control and elimination of this disease. Study in Porto Alegre pointed alcoholism, TB / HIV, the fact that the patient does not reside with family and low education as predictors of dropout. The dropout rate in the general population of patients with active tuberculosis was 10.7% (8.0% - 17.0%). Abandonment occurred more often within the first three meses8. In Porto Alegre, 32.5% of new TB cases are diagnosed in hospitals. Twenty percent of these patients do not bind, after discharge, the Tuberculosis Control Program (TCP), ie, the patient egress from the hospital does not reach the basic health unit (BHU) reference for further monitoring and treatment, which is considered a serious flaw in the process control of the disease.
A crossover trial with healthy volunteers will be conducted. Three sessions will be performed with at least 48 hours washout period to minimize carry-over effects. In each session, volunteers will be submitted to: fatigue and attention levels evaluation, handwriting test, serial reaction time task (SRTT) before and after ctDCS conditions and after session, a performance perception evaluation.
Diabetic macular edema (DME), wet-AMD and macular edema secondary to vein occlusions are the leading cause of blindness in developed countries. Several therapies have been studied as such laser treatment and intravitreal injections of corticosteroids or anti-VEGF drugs. In terms of public health the long term treatment with the current available drugs is very expensive and new therapies with the same or better effect should be investigated. This study intends to evaluate the efficacy and safety of intravitreal injections of ziv-aflibercept for the treatment of patients with DME, wet-AMD and macular edema secondary to vein occlusions.
The purpose of this study is to demonstrate that rivaroxaban is superior to placebo for reducing the risk of the primary composite outcome as defined by objectively confirmed symptomatic lower extremity proximal deep vein thrombosis (DVT), asymptomatic lower extremity proximal DVT, symptomatic lower extremity distal DVT, symptomatic upper extremity DVT, symptomatic non-fatal pulmonary embolism (PE), incidental PE, and venous thromboembolism (VTE)-related death in ambulatory adult participants with various cancer types receiving systemic cancer therapy who are at high risk of developing a VTE.
This study aimed to determine the efficacy and safety of QAW039 150 mg and QAW039 450 mg, compared with placebo, when added to GINA (Global Initiative for Asthma) steps 4 and 5 standard-of- care (SoC) asthma therapy (GINA 2016) in the following two populations: - patient with inadequately controlled severe asthma and high eosinophil counts at baseline (eosinophil count at Visit 1 ≥250 cells/ µl) (sub-population) - patients with inadequately controlled severe asthma (overall study population) Inadequate control is defined as partly controlled or uncontrolled asthma (GINA 2016).
The aim of the study was to evaluate the therapeutic action through the diameter of the lesion, of low level laser (LLL) associated to photodynamic therapy (PDT) in oral mucositis (OM) lesions, in young patients. A randomized clinical trial blinded, split-mouth was performed. The study sample consisted of 15 cancer patients (3-16 years old) of Aldenora Bello Hospital (São Luís, Maranhão, Brazil). Random allocation by lot of treatments (PDT + LLL and LLL) to quadrants of the oral cavity was performed, and the patient was his own control. Patients were masked about therapy performed on each side of the arch. The evaluation period of both therapeutic regimens was 8 days, and the outcome assessed was the lesion size (measured in cm²). Friedman and Wilcoxon tests were applied and the effect magnitude calculated. The significance level was 5%. Statistically significant difference was observed between the groups for the lesion diameter of the 6th to the 8th day (greater regression of lesion size for the PDT + LLL group), which was confirmed by a difference magnitude moderated. Based on the findings, it is concluded that PDT + LLL showed greater therapeutic effect when compared to LLL in reducing the severity of OM lesions.
