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.
This is a double blind randomized clinical trial to evaluate the effect of radial shock waves on functional recovery of the upper limb of patients with sequelae of ischemic strokes in the territory of the middle cerebral artery. A total of 20 patients will be enrolled and will undergo motor, functional and cortical excitability evaluations before and after four weekly sessions of radial shockwaves. 5,000 pulses with a frequency of 15 Hz and 3.5 to 4 bar of air pressure will be applied to the active group, resulting in an energy flux density (EFD) of approximately 0.07 mJ/mm2. The sham group will receive identical treatment, except for the fact that no energy flux will be applied.
The primary objective of this study is to continue to provide Darunavir (DRV) to pediatric patients who previously received DRV in any of three pediatric clinical studies sponsored by Tibotec Pharmaceuticals and continue to benefit from using it, in countries where DRV is not yet commercially available for the pediatric patient, is not reimbursed or cannot be accessed through another source (like access program or government program).
OOsteoarthritis (OA) is a chronic joint disease characterized by progressive degeneration of cartilage and bone tissue, leading to the appearance of subchondral cysts, osteophyte formation and synovial inflammation. Although the causes of OA are still poorly understood, biomechanical stresses able to reach the articular cartilage and subchondral bone, biochemical changes in cartilage and synovial membrane, as well as genetic factors are important items in its pathogenesis. Although there is no cure for OA, treatment is directed to each individual patient, seeking to minimize pain, maintain or improve joint range of motion and limit disability. New therapies able to accelerate regeneration and tissue repair process are being discussed. The viscosupplementation with hyaluronic acid (HA) have been shown to be an effective and safe treatment alternative in the fight against knee OA, in addition to HA, worth highlighting the therapeutic effects of growth factors derived from autologous platelets. The platelet-rich plasma (PRP) appears as an autologous therapy, non-immunogenic, able to induce healing and repair of bone soft tissue. This study aims to evaluate the clinical efficacy, comparing treatment with PRP and the combination of HA and PRP in the treatment of knee OA. To this, 120 will be selected OA patients with mild, moderate and severe (Grade II, III and IV). Selected patients will be scheduled for the procedures and randomly assigned randomly. In PRP be determined concentrations of the growth factor PDGF, TGFb 1, VEGF, EGF, by the method Bio Plex®.\. Functional evaluations will be conducted through questionnaires (WOMAC and SF-36) as measures of function and quality of self-reported life. The walking and strength test will be performed before and during periods of 90.180 and 360 days after the first application. The main motivation for the development of this study is the lack of randomized, double-blind clinical studies in the literature, and also based on the favorable results researchers have obtained, both with the use of HA, as the use of PRP in accelerating the process scar, preventing the development of arthrosis above. Therefore, we believe that the PRP, with its growth factors associated with synthetic HA play a synergistic action that should be studied in detail, in order to establish an effective therapeutic approach in the treatment of patients with knee OA.
It is a study of clinical and interventional character, in which individuals who participate in the intervention will be selected for convenience of the project database entitled "Second Cycle Diagnosis and Intervention Food Situation, Nutrition and Noncommunicable Disease More Prevalent Population of the city of João Pessoa / PB ". They will be invited to participate in the intervention female subjects, overweight or obese, aged 20 and 59 years. The selected individuals will be distributed randomly into four groups: receive daily supplementation of 01 capsules containing 400 mg of vitamin E synthetic source (Group 1); receive daily supplementation of 01 capsules containing 400 mg of natural source vitamin E (Group 2); receive daily supplementation of 01 placebo capsule (control group); and non-intervention group. Individuals of intervention groups will receive dietary plan respecting individual needs, in order to control weight during the 08 weeks period. The subjects of the group without intervention, did not follow a diet plan, nor did they take vitamin E or placebo capsules, and were asked to continue their current eating habits over the 8-week period This project aims to evaluate whether vitamin E supplementation may modify the methylation and microRNAs profile.
This study evaluates the impact of soft tissue grafts on soft tissue recession following immediate implant, provisional and bone graft placement in compromised sockets. One third of the patients received a collagen matrix (CM group), another third received a connective tissue graft removed from the palate (CTG group) and the final third did not receive any soft tissue graft (CTL group).
Background Endothelial dysfunction is one of the early events in atherosclerotic plaque development. It is characterized by an increased ratio of substances with vasoconstrictive, pro-thrombotic, and proliferative properties over substances with vasolidatory, antithrombogenic and antimitogenic properties. Endothelial dysfunction is also associated with high-risk patients with coronary artery disease. Hyperglycemia, obesity, hypertension and fat mass also impair the endothelium by increasing the expression of cytokines, inflammatory markers and vascular markers. Hypothesis Administration of dapagliflozin in addition to metformin background with clinical or subclinical cardiovascular atherosclerotic disease improves endothelial function when compared to those using glibenclamide in addition to metformin. Objectives Evaluate the effect of dapagliflozin vs glibenclamide on a metformin background on endothelial function in patients with clinical or subclinical cardiovascular atherosclerotic disease and poorly controlled diabetes. Enpoints Prymary Change in flow mediated dilation (FMD) and its related endpoint (FMD post reperfusion lesion) between the randomization visit and over 12 weeks of treatment. Secondary Change in plasma nitric oxide, isoprostane, ICAM-1, VCAM-1, ET-1, leptin, adiponectin, C-reactive protein, TNF- α, interleukin-6, interleukin-2, weight and body composition (% of fat mass and % free fat mass) at the randomization visit and over 12 weeks of treatment. 3 Design Randomized, parallel-group, comparative, prospective clinical study. The study is divided in two phases: Run-in and Randomization. In the former phase, which must have the maximum period of 16 weeks, patients will visit the outpatient to adjust metformin and blood pressure medications. After run-in phase, patients that fulfill inclusion criteria will perform an ambulatory blood pressure monitoring (ABPM) in order to asses BP; body composition will be assessed by dual x-ray absorptiometry (DXA); endothelial function as assessed by flow mediated dilation and vascular cytokines. Patients will by randomized to dapagliflozin or glibenclamide on a metformin background. After 12 weeks, the ABPM, DXA and endothelial function will be assessed.
To analyze changes on respiratory muscle strength, peripheral and functional capacity of critically ill patients with clinical and surgical etiology, breathing spontaneously and bedridden, within 48 hours of admission to the intensive care unit (ICU) and if there are correlations among these variables. This is an observational study. Respiratory muscle strength will be assessed through the maximum inspiratory pressure (MIP) and maximal expiratory pressure (MEP) and peripheral muscle strength, by the Medical Research Council score (MRC) and hand grip test and functional capacity through the Functional Independence Measure (FIM) and Physical Function ICU Test Score (PFIT-s) in the period between 24h and 48h of hospitalization in the adult ICU. For descriptive purposes, the sample will be stratified according to clinical and surgical characteristics. Correlations will be determined using the Pearson test, with significance level of p <0.05.
