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 clinical study involving 44 patients, evaluating the effect of mesenchymal cells on rotator cuff repair. The primary outcome will be post-operative MRI tendon integrity and secondary outcomes clinical assessment by the UCLA and American Shoulder and Elbow Surgeons (ASES) scales and pain by visual analog scale (VAS).

Smoking is the leading cause of avoidable death in the world. Smoking is associated with the development of cardiovascular and respiratory diseases, as well as being considered a leading cause of cancer death. Data show that smokers have increased cardiovascular risk in relation to former smokers, even in comparison with individuals who have had a long and intense history tobacco use. Considering this scenario, some drugs are used in tobacco cessation therapy. The first-line anti-smoking treatments approved by the Food and drug administration ( FDA ) are nicotinic reuptake therapy, bupropion ( norepinephrine and dopamine reuptake inhibitor) and varenicline ( partial agonist of nicotinic receptors composed of subunits alpha4Beta2 ). A metanalysis of 16 clinical studies indicated that smokers treated with bupropion had a higher abstinence rate compared to those receiving placebo - Odds ratio (OR ) - of 1,97 for treatment success. Varenicline is more effective compared to others smoking cessation drugs approved by the FDA, with an OR of 2,27 ( IC 95% 2,02-2,55 ) compared to placebo. However, Varenicline is much more expensive than bupropion. Significant advances in genetics have made the variability of the individual response to drugs, as far as efficacy as well as the rate of adverse effects, begin to be specifically investigated through pharmacogenetics studies.
The aim of this study is to compare the effects of balance training in a virtual environment with and without physiotherapeutic intervention on the motor function, balance and gait in chronic stroke patients. It is a prospective, single blinded, randomized clinical trial performed at Center of Research of the Department of Speech Therapy, Physical Therapy and Occupational Therapy of São Paulo University. Forty patients will be randomly assigned in control and experimental group.

Background: Multiple sclerosis (MS) is an autoimmune disease, for which the forms of treatment are medication and rehabilitation. However, in vitro and in vivo studies have demonstrated that photobiomodulation can be an effective treatment modality for inflammatory diseases, including MS. Photobiomodulation has a broad range of benefits, such as the avoidance of cell and tissue death, the stimulation of healing and injury repair, reductions in pain, edema and inflammation, cell proliferation and even apoptosis. The outcomes of photobiomodulation include the regeneration of cells, the stimulation of the growth of Schwann cells, a reduction in spasticity, functional improvements, a reduction in nitric oxide levels and the upregulation of the cytokine IL10, demonstrating that this therapeutic modality can offer neuro-protection. Methods: A randomized, controlled, double-blind, clinical trial is proposed. The patients will be divided into six groups. Groups 1 and 2 will receive sham and active photobiomodulation in the sublingual region, respectively. Groups 3 and 4 will receive sham and active photobiomodulation along the spinal cord, respectively. Group 5 will receive placebo treatment with photobiomodulation on the skin in the region of the radial artery with a specific bracelet. Group 6 will be treated with photobiomodulation on the skin in the region of the radial artery with a specific bracelet. Discussion: Treatment for MS is directed at the immune response and slowing the progression of the disease. This is one of the first clinical trials with sublingual and along the spinal cord photobiomodulation, which could help establish a new, promising treatment of the disease associated with pharmacological treatment.
The objective of this natural history study is to gain a better understanding of the progression of choroideremia (CHM) and add to the knowledge base for this rare disease.
