There are about 9959 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 objective of this randomized clinical trial is to evaluate the survival of restoration with high viscosity glass ionomer cement (HVGIC) with pre-etching with polyacrilic acid compared with no pre-etching in order to treat occlusoproximais caries lesion in primary molars, as well as the impact of those treatments in the caries lesion progression, the cost-efficacy of the procedures and the discomfort reported by the patient. Children of 4 to 8 years will be selected in the Pediatric Dentistry Clinic of Universidade Ibirapuera. 192 teeth will be randomized in 2 experimental groups: (1) HVGIC restoration with pre-etching and (2) HVGIC restoration with no pre-etching. Will be considered as primary outcome the survival of the restoration evaluated after 6, 12, and 24 months by two trained examiners. The carious lesions progression will be evaluated after 24 months of follow-up. The time of the treatments and the cost of the materials will be considered to estimate the cost-efficacy of each treatment. The discomfort reported by the participant will be measured after each procedure following the Wong-Baker scale. For the primary outcome, Kaplan-Meier survival and the Long-Rank test will be used in order to compare the two groups. Cox regression will be performed in order to evaluate thee influence of explanatory variables on the outcome.
A prospective study to evaluate and compare implants placed in preserved versus non-preserved extraction sockets using L-PRF (Leucocyte- and platelet-rich fibrin) after 1, 3 and 5 years.
The purpose of this study is to determine the effectiveness of relatlimab plus nivolumab, alone or in combination with various standard-of-care treatments in participants with gastric cancer (GC) or gastroesophageal junction (GEJ) adenocarcinoma that has come back or spread to other places in the body after prior therapy.
The primary purpose of this study is to determine the overall response rate (ORR) during induction therapy with the combination of ixazomib, thalidomide and low-dose dexamethasone in specific time points.
The purpose of this study is to determine in hospitalized adult participants infected with human metapneumovirus (hMPV - a virus closely related to respiratory syncytial virus (RSV) and has been identified as an important cause of acute respiratory infections, affecting all age groups) the dose-response relationship of multiple regimens of lumicitabine on antiviral activity based on nasal hMPV shedding using quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) assay.
This is a randomized controlled trial project to analyze the effectiveness of lumbar motor control exercises and lumbar resistance training on pain, functional, kinesiophobia and trunk strength in individual with chronic low back pain. The project has two parallel arms and will be supervised by physiotherapists (motor control exercises) and physical education professionals (resistance training). The participants will be Militaries of the Military Fire Department of the Federal District who presents in the recruitment regular low back pain more than 3 months. The two groups will be supervised in12 weeks of exercises in the Physical Activity Center of Military Fire Department of the Federal District. Our hypotheses is that the resistance training effects wil be superior to motor control exercises only for trunk strength (isokinetic flexion and extension).
This is a study of experimental medication BMS-986205 given with Nivolumab with or without chemotherapy compared to chemotherapy in participants with previously untreated stage IV or recurrent non-small cell lung cancer.
A single-arm, open-label study to assess the overall safety of rovalpituzumab tesirine in participants with relapsed or refractory delta-like protein 3 (DLL3) expressing small cell lung cancer by evaluating the frequency of high grade (>= Grade 3) select treatment-emergent adverse events (TEAEs).
The study investigates the effects of high intensity interval training (HIIT) versus continuous training (CT), combined or not with fasting, on capillary density, microvascular function, cardiometabolic risk markers, functional capacity, and quality of life, in overweight or obese sedentary women with cardiometabolic risk factors. The use of HIIT could promote greater improvements in these parameters than CT. Furthermore, the positive effects of exercise may increase when it is performed in the fasting state, compared to exercise performed in the fed state.
Study to enroll up to 1000 adult patients (>18 years) presenting with febrile or rash illness of short duration (<72h) in designated clinics in the State of Sao Paulo, Brazil.
