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.
Performing physical exercise alters the body's homeostasis, and recuperative techniques seek to anticipate and potentiate the body's recovery. One of the ways to demonstrate a recovery of the organism is the resumption of autonomic cardiac modulation analyzed through heart rate variability (HRV), a method of global assessment of the behavior of the autonomic nervous system. Among the recovery techniques, massage is the most widely used technique in sports. Therefore, the objective of the study will be to measure the effects of massage as a recuperative technique on autonomic cardiac modulation at different moments of application. It will be a randomized clinical trial where there will be five stages of evaluation. In the first stage, the behavior of the baseline HRV will be evaluated, in the second stage the behavior of the HRV in front of the massage, in the third stage the behavior of the HRV in front of the stress protocol, in the fourth stage the HRV behavior after the stress protocol and immediately after Execution of the massage and finally in the 5th stage where the HRV behavior will be evaluated after the stress protocol and the massage application will be performed at the moment of HRV recovery. The stress protocol will be composed of squats followed by jumps and wingate test, and massage by slides in the anterior thighs and posterior trunk. The HRC indexes in the time domain, frequency domain and Poincaré plot, as well as cardiorespiratory parameters and a questionnaire on individual touch perception will be analyzed. The descriptive statistical method will be used and comparisons of cardiorespiratory parameters and HRV indices will be performed using the analysis of variance technique for repeated measures model in the two factor scheme. The level of significance will be p <0.05 for all tests.
The aim of this randomized controlled clinical trial of superiority will be to evaluate the effect of 3 g of omega-3 polyunsaturated fatty acids and 100 mg of aspirin daily supplementation over a period of 180 days as adjunct to non-surgical therapY of patients with generalized aggressive periodontitis. Probing depth, clinical attachment level, gingival index and concentration of microorganisms and cytokines at baseline, 3, and 6 12 months after the procedure will be evaluated.
The aim of this randomized controlled clinical trial of superiority will be to evaluate the effect of 3 g of omega-3 polyunsaturated fatty acids and 100 mg of aspirin daily supplementation over a period of 180 days as adjunct to surgical therapy of residual pockets from patients with generalized aggressive periodontitis. Probing depth, clinical attachment level, gingival index and concentration of microorganisms and cytokines at baseline, 3, and 6 months after the procedure will be evaluated.
This study is designed to evaluate the cosmetic benefit provided by twice daily application of a developmental moisturising cream with niacinamide for 8 weeks in healthy female participants with sensitive, oily, blemish-prone skin.
Introduction: the peripheral obstructive arterial disease is an condition that affects around 15% of the world population interfering in muscle strength, life quality and functional capacity of patients.
The family of cytochrome P450 (CYP) is the most important drug metabolizing enzymes which contributes to the metabolism of a large proportion of drugs in humans. Some CYP450 enzymes reduce or alter the pharmacodynamic activity of many drugs and are involved in oxidative metabolism and elimination of many drugs commonly used by the population. Polymorphisms in CYP2C8 and CYP2C9 are common in different populations around the world and genetic variations in these alleles can cause decreased enzyme activity to nonsteroidal anti-inflammatory drugs (NSAIDs) such as celecoxib, diclofenac, ibuprofen, indomethacin, lornoxicam, meloxicam, valdecoxib, piroxicam, tenoxicam and naproxen. This compromise the bioavailability of the drug can alter the pharmacokinetics of these drugs and patients with mutations in these genes can exhibit increased plasma concentrations of values and areas under the curve (AUC), in addition to decreased clearance of drugs. Associations between NSAIDs and gastric protectors or proton pump inhibitors (PPIs) have become common nowadays, especially in patients who make chronic use of these drugs. Naproxen associated to esomeprazole, a proton pump inhibitor (PPI), was launched in the market recently and its application in acute pain is not yet elucidated. Esomeprazole suffers strong influence of CYP2C19 (hepatic drug-metabolizing enzyme that degrades PPIs). In patients with high enzyme activity of the CYP2C19, the drug can suffer high enzymatic degradation, and its diminished effect. Moreover, in patients with low enzyme CYP2C19 activity, the effect of acid inhibition by PPIs can be very strong.
As a T2T, our patients with idiopathic inflammatory myopathies will receive pulse therapies with methyprednisolone and/or human intravenous immunoglobulin, or only methyprednisolone at disease onset. This scheme is an internal routine protocol of our Service.
Physical training may improve physical capacity and health parameters in various systemic autoimmune diseases, including idiopathic inflammatory myopathies. Therefore, the present study will assess the role of an exercise training program in patients with idiopathic inflammatory myopathies.
The use of lipid lowering agents in patients with idiopathic inflammatory myopathies is controversial. Therefore, the aim of the present study is to assess clinically and laboratory the impact of lipid-lowering agents in this population.
Physical training may improve physical capacity and health parameters in various systemic autoimmune diseases. Therefore, the present study will assess the role of an exercise training program in patients with relapsing polychondritis.
