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.
Randomized, comparative and prospective study between Conventional Endoscopic Mucosal Resection for the removal of flat or sessile colorectal lesions without previous attempt to resection.
The purpose of the study is to investigate whether corifollitropin alfa (MK-8962), administered alone for 12 weeks and then in combination with human chorionic gonadotropin (hCG) for 52 weeks, increases the testicular volume in adolescent males aged 14 to <18. In addition, the study will evaluate participants for safety, tolerability and for the development of corifollitropin alfa antibodies. No formal hypothesis will be tested for this estimation study
This study aims to analyze the efficacy of intravenous tranexamic acid (TXA) in patients undergoing total hip arthroplasty (THA).
Early diagnosis and appropriate treatment for COPD subjects are both critical to minimize the progression of COPD and improve outcomes. Also, evidence suggests that high eosinophil (specific type of white blood cell that protects body against certain kinds of germs) level is associated with increased risk of both moderate and severe exacerbations in COPD subjects. To date, there is insufficient amount of data that describes the prevalence of COPD in Brazilian primary care units. Thus, this multicenter, cross-sectional study conducted in five centers located in five different Brazilian cities will provide estimation about the prevalence of COPD in primary care and will also determine the levels of eosinophils in subjects with confirmed COPD diagnosis. Approximately 2,500 eligible subjects are expected to be enrolled in the study.
The purpose of this study is to investigate the effects of a functional exercise program associated with Low Level Laser Therapy (LLLT) on pain, functional capacity and quality of life of individuals with fibromyalgia. Half of participants will receive functional exercise and LLLT, while the other half will receive functional exercise and placebo LLLT.
The objective of this study is to evaluate the IOP variation before and 30 days after performing phacoemulsification through pneumatic tonometry, in addition to evaluating the factors possibly related to this variation.
This study compares patients with post traumatic elbow stiffness and evaluate the range of motion improvement with two types of treatment: surgical release versus non-surgical rehabilitation protocol with orthoses.
A crossover trial with spinal cord injury volunteers will be conducted. Three 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 quantity and quality of sleep, type of eating, fatigue and motivation level, Ashworth scale spasticity, cortical brain activity measures through simple pulse transcranial magnetic stimulation (pTMS), spinal cord activity measures through electrical stimulation and non-invasive brain stimulation (rTMS)
Asthma is a chronic inflammatory disease of the Airways of recurring character. The obstruction to the airflow carries the short-and long-term consequences that require prophylactic interventions and in emergency many times. The children due to immaturity of the respiratory system associated with the use of steroids suffer structural consequences, as for example, the physical deconditioning that intensifies the symptoms of the disease and affects negatively on the quality of life. Therefore, to set up a physical training program suitable for the paediatric population, using resources to increase adherence to the regular practice of exercises, can be the difference for the reduction of the number of exacerbations, the sensation of Dyspnea and the doses of medication, positively impacting the clinical picture of child asthmatic. The investigators conducted a randomized, blinded in order to evaluate the effects of training with active video game associated with resisted exercise the exercise in inflammatory and functional outcomes resisted in asthmatic children.
Obstructive sleep apnea (OSA) is a common clinical condition associate with a negative impact not limited to the patients but also to the partner that sleep in the same bed. Is it reasonable to speculate that the partner suffer sleep deprivation, increased level of irritability, insomnia, fatigue, among others due to the loud snoring caused by the OSA patient. Although previous data reported impaired sleep quality in partners of patients with OSA, it is not clear in literature whether OSA promotes cardiovascular impact and if the treatment of OSA promotes some cardiovascular benefits in (the) partner beyond the improvements in the subjective and objective sleep. Thus, the main objectives of this randomized controlled study are: to evaluate the impact of three months of randomization (treatment with nasal CPAP or nasal strips) on the endothelial function, blood pressure (ambulatory blood pressure monitoring), sleep duration (wrist actigraphy for 1 week) and sleep quality (Pittsburgh Questionnaire) and the frequency of OSA in the bed partners of patients with moderate to severe OSA.
