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 purpose of this study is to establish, through ultrasound, measurements of the thigh muscles (Biceps Femoris and Vastus Lateralis)and the chronic effects of a static stretching program on the muscle-tendon unit these muscles.
The objective of this study is to analyze the correlation between pleural elastance and the radiological effectiveness (measured by chest tomography) of pleurodesis performed via catheters in patients with RMPE. The secondary objectives of this study are: correlate pleural elastance with quality of life, analysis of dyspnea and pain after the procedure, clinical effectiveness, complications and mortality in 30 days.
The aims of this study were to determine the sucrose and liquid oral pediatric medicines of long-term effect on dental biofilm pH to evaluate the cariogenic potential in vivo.
There is a claim that creatine supplementation might affect kidney function, especially in those consuming a high-protein diet. The aim of this study was to investigate the effects of creatine supplementation on kidney function in resistance-trained individuals ingesting a high-protein diet.
The purpose of this study was to verify physiological responses to constant-load (continuous) vs. variable-intensity (interval) during 14 weeks of aerobic exercise on active men. The hypothesis was that would be differences in physiological variables on distinct modes of execution performed on the treadmill over a period of 14 weeks of training.
The cobalt-chromium (CoCr) partial denture has been made for a long period. It respects biomechanical principles, providing harmony between mechanical and biological activities. The fundamental principles of biomechanics applied in the manufacture of steel structure are: retention, reciprocity, attachment and stability. To get the proper planning, we need to assess the dental support system, with its qualitative and quantitative values. But conventional dentures has a inherent problem which is the metallic elements apparent and in some cases the stiffness of the component support elements that generates stress. The Thermoplastic partial dentures increase aesthetics in replacement of metal structures in oral rehabilitation. So many treatments are being done in everyday practice without a defined concept on various aspects of its construction and oral applicability. This trial aims to assess the basic parameters of both dentures in: nutrition, speech therapy, chewing force, chewing efficiency and quality of life. 60 years old or older patients who require removable prosthesis. These will be randomly selected for the fabrication and installation of removable partial dentures (Gold Standard - control group - CoCr partial denture) and thermoplastic partial denture(experimental group). Before beginning the work, selected patients will make some preliminary tests such as controlling the individual condition, they are: - three questionnaires: - instrument for assessing quality of life related to oral health, GOHAI - General Oral Health Assessment Index of Atchinson & Dolan - instrument for assessing the social and economic profile of ABEP (Brazilian Association of Research Companies) CCEB 2011; - Instrument for assessing cognitive condition MINI-MENTAL; - Speech evaluation - Nutritional assessment; - Evaluation of masticatory efficiency and - Chewing strength. After preliminary assessments patients will be subjected to treatments for manufacture of partial dentures. After the installation (end of the technical construction of the dentures) and the adjustments appointment the tests will be repeated and in successive control periods of 3 months, 6 months, 12 months, 18 months and 24 months respectively, when the tests will do again now to see if there was a change in the initial condition.
The purpose of this study is to determine whether the non-invasive negative pressure treatment with the use of the device Vacuum Bellfor is effective for the pectus excavatum treatment
The purpose of this study is to verify and analyse psychological and physiological effects of olfactory aromatherapy and yogatherapy respiratory exercises, together and separately, on the quality of life, levels of stress, quality of sleep and intensity and frequence of hot flashes in climacteric women.
The primary objective of this study is to evaluate the non-inferiority of switching to a tenofovir alafenamide (TAF)-containing fixed dose combination (FDC) relative to maintaining tenofovir disoproxil fumarate (TDF)-containing combination regimens in virologically suppressed HIV-infected participants as determined by having HIV-1 RNA < 50 copies/mL at Week 48.
Crack addiction has become a severe health problem in Brazil. Today, crack addiction is the primary cause for inpatient treatment for all illicit substances. When compared to cocaine, crack users develop much faster diagnoses for crack dependence, shows a more compulsive pattern of use, has higher probability of living or have lived in the streets, and of engaging in illegal activities. Consequently to this, mortality of crack addicts is 7 times higher than for the rest of the population. Despite all efforts being made for the development of effective pharmacological treatments for stimulant addiction (crack included), up to today, there is no robust evidence of efficacy of any pharmacological treatment. For that reason, the use of evidence based psychosocial interventions is so important for treating this population. Although today open treatment facilities in Brazil are more and more starting to use evidence-based interventions such as motivational interviewing, cognitive behavior therapy, relapse prevention and coping skills, such treatments present very modest results when treating crack addiction. The biggest difficulties encountered when treating this population are maintaining patients in treatment, reducing crack use and achieving continued abstinence. A psychosocial treatment based in behavioral principals' named Contingency Management (CM) is widely applied in the USA. Recent meta-analyses and review studies present robust evidence that, when applied alone or in adjunction with other psychosocial and pharmacological treatment, CM is the most effective treatment for what regards, treatment retention, reducing drug use and promoting continued abstinence. The purpose of this study is to evaluate if Contingence Management (CM) can be affective in the treatment of crack addiction in Brazil. To accomplish this, 60 individuals (male and female from 18 to 65 years of age) seeking open treatment for crack addiction will be randomized to 2 treatment conditions (Standard treatment (ST) or ST+CM. Both treatments will last 12 weeks with 3 and 6-month follow-up. In both groups patients will be encourage to leave urine samples 3 times week. Hypotheses: Patients receiving ST+CM will stay longer in treatment, have more negative tests for cocaine/crack, and achieve longer periods of cocaine/crack abstinence when compared to patients receiving ST alone.
