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.
According to the International Association for the Study of Pain (IASP), the temporomandibular pain and dysfunction syndrome (TMD) is characterized as a subset of orofacial pain, whose signs and symptoms include pain or discomfort in the temporomandibular joints. Pain is considered one of the most common and limiting clinical manifestations. One of the most used resources to treat muscle pain is the low-level laser therapy (LLLT), However, the mechanisms responsible for the effects observed in clinical trials remain poorly elucidated, as well as therapy with light emitting diode therapy (LEDT) which, has some advantages, among them the larger area radiation point and low cost. However, its effects remain elusive in intraoral application in temporal muscle, lateral and medial pterygoid muscle. Assuming that there is need to investigate therapeutic resources that combine not only different wavelengths as well as different light sources (LED and LLLT), this study aims to evaluate the effect of photobiomodulation with a combination of different light sources on pain, joint mobility, equity and quality of jaw movements after treatment in patients with TMD. It will be made a randomized, placebo-controlled and double-blind clinical trial. Individuals participate with myogenic temporomandibular disorder, being allocated into 2 groups randomly and stratified by the method of sealed envelopes. The results will be evaluated using: RDC/TMD, digital caliper, visual analog scale, and kinematics. The protocols will be used in a 6 sessions and will be evaluated in four different moments. The analyses of the data will be performed by adopting a significance level of 5%.
The study is a randomized, double-blinded, placebo-controlled trial that will include the participation of 69 women, aged 18-40 years. The aim of the study is to test nutritional strategies that help to minimize the effects of muscle damage induced by exercise. The procedures will be performed at the Federal University of Health of Porto Alegre (UFCSPA).
Context: Cesarean section is the most common surgery in women, both in developed and underdeveloped countries. However results are conflicting report in which material for intradermal suturing get better aesthetic result. Objective: To compare the aesthetic appearance of two suture materials, polyglecaprone 25 and polyamide (nylon) with intradermal sutures for skin closure in women undergoing cesarean section first. Methods: This is a clinical, prospective and randomized study which was conducted in the Department of Gynecology and Obstetrics of a tertiary Institute, Hospital das Clinicas Samuel Libânio, in PousoAlegre, Estate of Minas Gerais. Sixty women undergoing cesarean section were first included and randomized into two groups: group I (n = 30) polyamide and group II (n = 30) polyglecaprone 25. Hypertrophy, color and width of the wound were evaluated, receiving a score, according to Trimbos table, six months after surgery. Later the results were compared to non-parametric statistical tests
Introduction: Hip motor control deficit and neuromuscular disorders of the gluteus medius influence the mechanics of patellofemoral joints through increased dynamic knee valgus and can lead to Patellofemoral Pain Syndrome (PFPS). Mechanoreceptors can be stimulated by an elastic tape, which sends desired tactile cues via afferent improving the functional support of the musculoskeletal system. Objective: To analyze the response to hip stabilizer muscle activation in street runners with PFPS through the application of elastic tape therapy. Methods: The investigators evaluated street runners between the ages of 18 and 45, who run at least 5km/week and had been suffering from pain for at least 3 months. The volunteers had been assessed in relation to their measurements, experience of pain and training routine, their medius muscle (GM) and biceps femoris muscle (BF) had also been tested with surface electromyography through pre-determined performance tests. The participants of both groups wore a bandage for 6 weeks (1 per week). However for the participants of the placebo group the investigators applied a different anatomical path without tension, eliminating all the therapeutic elements. The volunteers were reassessed following the trial. Hypothesis: Expected to observe that elastic tape therapy do result in any improvement in the activation of hip muscles and improvement of pain in street runners with patellofemoral pain syndrome.
Mepolizumab is a humanized monoclonal antibody. In conditions where eosinophilia is considered to play an important part in the pathology, including eosinophilic asthma, HES, and eosinophilic granulomatosis with polyangiitis, a consistent reduction in blood eosinophil counts is observed in association with mepolizumab administration, with concomitant clinical improvement. This is a 32-week treatment period, randomized, double-blind, placebo-controlled, parallel group, multicentre study of mepolizumab in adolescent and adult subjects with severe HES receiving standard of care (SoC) therapy. This study will demonstrate the efficacy of mepolizumab compared with placebo based on maintenance of control of HES symptoms during the treatment period. The study will comprise of a screening period of up to approximately 4 weeks followed by a 32-Week study treatment period (subjects will be randomized 1:1 to placebo or mepolizumab) and up to 8-week additional follow-up period (12 weeks after the last dose of study treatment).
Muscle strength can be measured by dynamometry, but the investigators did not find in the literature the study of this technique in the quadriceps of patients with chronic kidney disease on hemodialysis. Analyze training impact conducted by cycle ergometer in quadriceps muscle strength in patients with chronic kidney disease during hemodialysis. This study will be a prospective, randomized. Inclusion of 46 patients followed by the dialysis unit of a university hospital, over 18 years, of both genders who underwent hemodialysis for more than six months and signed the consent form and enlightened. Patients will be divided into two groups: Intervention (n = 23) and control (n = 23). All will be evaluated for demographics and quadriceps strength given by standardization of technique, with hard and windy belt. The control group will be reassessed after two months of the initial assessment, since the intervention group held two months of training in hemodialysis a physical therapy protocol with the cycle ergometer.
The study is divided into 2 parts. The first part of the study will be double-blinded and will last for 24 weeks. During this time, participants will be randomized in a ratio of 2:1 to receive either evolocumab once monthly (QM) or placebo QM. The second part of the study is a 24-week open label extension period. During this time all participants will receive evolocumab QM. The clinical hypothesis is that subcutaneous evolocumab QM will be well tolerated and will result in greater reduction of low density lipoprotein cholesterol (LDL-C), defined as percent change from baseline at Week 24, compared with placebo QM in human immunodeficiency virus (HIV)-positive participants with hyperlipidemia or mixed dyslipidemia.
Context: The neuraxial blocks, spinal anesthesia and epidural anesthesia are among the most frequently performed procedures worldwide, and despite the advancements of medical equipment, remain dependent on experience and practice of the anesthesiologists. Although antisepsis takes part of the daily routine, there are still no solid scientific evidence of the most appropriate antiseptic for these procedures. Objective: To compare the 70% alcohol and 0.5% chlorhexidine alcohol solution in skin antisepsis for the neuraxial blocks. Methods: This is a clinical trial, a prospective, randomized study. There will be selected, consecutively, 70 patients candidates for neuraxial blocks. Patients will be randomly assigned to group A (n = 35), in which the antisepsis will be performed with alcohol 70%, and to group B (n = 35), in which the antiseptic will be performed with the 0.5% chlorhexidine in alcoholic solution. Samples will be collected with swabs in an area of 25 cm² for bacterial cultures three times: in pre-antisepsis moments, in the second minute after antisepsis, and immediately after the puncture. The number of colonies forming units per square centimeter (CFU / cm²) will be counted. The data will be analyzed statistically.
This is a multicenter, Phase II, randomized, double-blind, placebo-controlled, active comparator (Cohort 1 only), parallel-group, dose-ranging study to evaluate the efficacy and safety of GDC-0853 in participants with moderate to severe active RA and an inadequate response to previous methotrexate (MTX) therapy (Cohort 1) or MTX and tumor necrosis factor (TNF) therapy who may have also had exposure to no more than one non-TNF inhibitor biologic (Cohort 2).
A randomized clinical trial comparing sequential nephron blockage (SNB) with dual blockade of the renin-angiotensin system (RAAS) plus bisoprolol (DBB) in the treatment of resistant arterial hypertension (RH) was designed to investigate the importance of the SNB and the contribution of its volume component versus DBB and the importance of the serum renin in maintaining BP levels. This randomized trial with two treatment arms could help tailor therapy by identifying a more effective choice to control hypertension whether by acting on the control of volume or sodium balance, or by acting on the effects of the RAAS on the kidney. Methods - Participants: 80 patients undergoing treatment for RH with losartan (100-200 mg), chlorthalidone (25 mg), and amlodipine (5 mg) will be randomly divided into two groups after applying inclusion and exclusion criteria. Group 1: Sequential nephron blockade (SNB Group) n = 40 Group 2: Dual blockade of the RAAS plus bisoprolol (DBB Group) n = 40 Intervention: SNB consists in a progressive increase in sodium depletion. After the administration of a thiazide diuretic (chlorthalidone) and aldosterone receptor blocker, low doses of furosemide are administered and subsequently amiloride is prescribed to enhance the natriuretic effect. The dual blockade of the RAAS plus bisoprolol is used to increase the effect of angiotensin receptor 1 blockers (ARBs). Therapy then requires sequentially adding an angiotensin converting enzyme (ACE) inhibitor to reduce the levels of angiotensin (Ang) II resulting from blockage of the Ang II receptor and then to administer a beta-blocker to decrease the elevated renin secretion due to both the ACE inhibitors and ARBs Objective: This study, which compares two antihypertensive treatment regimens in patients with RH, has the following objectives: to demonstrate the therapeutic efficacy of SNB against DBB in RH patients, and to assess the side effects and adherence to treatment over 20 weeks of treatment. Enrollment: The eligibility criteria will follow those shown in the flowchart for the diagnosis of RH of the First Brazilian Position on RH. Patients will be excluded if they have: chronic renal failure, atrial fibrillation/atrioventricular block, contraindication to the drugs that will be used, refusal or failure to follow the regimen and secondary hypertension. Follow-up: Patients will be analyzed in five visits at intervals of 28 days for 20 weeks
