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 primary objective of this study is to evaluate the effect of presatovir on respiratory syncytial virus (RSV) viral load in autologous or allogeneic hematopoietic cell transplant (HCT) recipients with an acute RSV upper respiratory tract infection (URTI), the effect of presatovir on development of lower respiratory tract complication, being free of any supplemental oxygen progression to respiratory failure, and pharmacokinetics (PK), safety, and tolerability of presatovir.
The latest randomized controlled trials and systematic reviews of resistance training performed by older adults reported that the systematic use of exercise in machines improves muscle strength and power, functional abilities, body mass and body balance. However, the effect of resistance training with elastic tubes exercises have not been studied in all the variables described above. The objective of this study is to analyze the effects of elastic tubes exercises on muscle mass, muscle strength, functional performance and postural control in elderly untrained.
The purpose of this study is to characterize the frequency of TTR mutations in subjects suspected of having cardiac amyloidosis
To investigate the effects of the use of occlusal splint over postural balance in individuals with signs and symptoms of temporomandibular disorder. The research group consists of 49 patients (36 getting occlusal splints and 13 as control group) between 18 and 75 years old, both genders, diagnosed as temporomandibular disorder (TMD) by RDC/TMD questionnaire and magnetic resonance imaging of the temporomandibular joints. The research is a randomized, controlled, prospective clinical study with intervention. Postural equilibrium will be evaluated by means of a force plate. In the randomization, the splinted group was under an occlusal-stability criterion as well as advised under therapeutic exercises while the control group got only orientation about therapeutic exercises. After 12 weeks, the groups were re-evaluated. The results will be analyzed by categorical data using absolute and relative frequencies as well as continuous data using average, median, standard deviation, 25 and 75 percentiles, besides minimum and maximum values; comparison between the times by non-parametric Wilcoxon, Mann-Whitney and ANOVA tests with a threshold of significance of 0.05.
The objective of this study is to evaluate the clinical success of AttraX Putty as a bone graft substitute for autograft in XLIF procedures.
Dose response curve to define the security and tolerable dose to be used for prevention and treatment of radiodermatitis in patients with breast or head and neck cancer.
Aerobic exercise has the potential to diminish blood pressure values. The aim of this study is to determine whether this potential is also applicable for those with resistant hypertension and whether exercise intensity plays a role in this context. We hypothesize that performing an aerobic exercise session reduces blood pressure values in resistant hypertensive patients in a dose-response relation with exercise intensity.
The purpose of this study is to investigate whether the use of a mobile app could improve knowledge and practice in nutrition counseling performed by primary care physicians in Brazil.
The purpose of this study is to determine whether education or aquatic physical therapy are effective in the treatment of osteoarthritis in Knee due to intensity of pain, function capacity, quality of life and kinetic.
Background: Beneficial effects from noninvasive ventilation (NIV) in acute COPD are well-established, but couple to nebulization is still challenging. Aim: To compare radioaerosol pulmonary deposition and radioaerosol mass balance in the different compartments (pulmonary and extrapulmonary) using vibrating mesh nebulizer (VMN) and jet nebulizer (JN) coupled to NIV.Methods: It was a crossover study involving 9 stable moderate to severe COPD randomly allocated for both phases of the study: Phase 1(NIV+MN,n=9) and phase 2(NIV+JN,n=9). Bronchodilators were delivered during NIV using a facemask (pressures of 12 cmH2O and 5 cmH2O - inspiratory and expiratory, respectively). Radioactivity counts were performed using a gamma camera and regions of interest(ROIs) were delimited. We determine aerosol mass balance from the lungs, upper airways, stomach, nebulizer, circuit, inspiratory and expiratory filters, and mask as a percentage.
