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.
Soil-transmitted helminths (STHs) are a group of parasitic worms that infect millions of children in sub-tropical and tropical countries, resulting in malnutrition, growth stunting, intellectual retardation and cognitive deficits. To control the morbidity due to these worms, school-based deworming programs are implemented, in which anthelminthic drugs are administered to children without prior diagnosis. The continued fight against these worms is aided by the London declaration on neglected tropical diseases, which helps sustain and expand global drug donation program, resulting in an unprecedented growth of deworming programs. However, the high degree of drug pressure makes deworming programs vulnerable to the development of anthelmintic resistance because they only rely on one drug with sometimes suboptimal efficacy and there is no availability of alternative drugs. Moreover, at present, there is no surveillance system to monitor the emergence and spread of anthelmintic resistance. It remains unclear to what extent the efficacy of drugs may have dropped and whether anthelmintic resistance is already present. This project aims to strengthen the monitoring and surveillance of drug efficacy and anthelmintic resistance in STH programs. As such, it will support deworming programs in their quest to eliminate STHs as a public health problem. The specific objectives of the first work package are to validate diagnostic tools to monitor drug efficacy and the spread of anthelmintic resistance, and to validate molecular markers for benzimidazole resistance. This study will be conducted at four different sites (Ethiopia, Tanzania, Lao PDR and Brazil) and will focus on school-aged children (age 5-14). At baseline subjects will be asked to provide a recent stool sample which will be processed using 3 different microscopic techniques (KK, Mini-Flotac and FECPAKG2). All children will be treated with a single-oral dose of albendazole (ALB) 400 mg and 14-21 days after treatment, a second stool sample will be collected from all children to again determine the fecal egg counts. At each sampling, stool is stored in preservative. Stored stool will be shipped to Belgium for DNA extraction and quantitative PCR (qPCR) analysis. A subset of the samples will be analysed by pyrosequencing to evaluate the single nucleotide polymorphisms in the b-tubulin gene. Pooling of the stored samples will also be performed to compare with the values obtained from analysing individual samples.
Physical exercises proves to be an option to revert a vicious cycle and aggravation of the painful that chronic low back pain can provide, which can improve the mobility and stabilization of the spine, muscle strength, motor coordination and general aerobic conditioning. In addition, photobiomodulation using light emitting diodes (LEDs) has attracted attention for acute and chronic pain and wound healing, being used as a resource for prevention and recovery of lesions. Thus, the present study aims to analyze the efficacy of aerobic training systematized with Deep Water Running associated with photobiomodulation in individuals with chronic nonspecific low back pain. Individuals of both sexes, sedentary, who present chronic low back pain, aged between 30 and 55 years (middle-aged individuals) who meet the inclusion and exclusion criteria will be invited to participate. Anthropometric measurements, maximal stress test, functional tests, physiological measures and questionnaires concerning disability and pain, besides psychological ones, will be carried out. After the evaluations, the participants will be randomized into three experimental groups with 15 participants in each: the first group will be the training group that will hold interval training sessions in addition to continuous training sessions (GT). The second group will perform the same training model, and before the training sessions the LED will be applied (GTL). And the third group will only receive the LED application (GL).
The purpose of this study is to compare the efficacy of treatment with ustekinumab or adalimumab in biologic naive participants with moderately-to-severely active Crohn's disease (CD) who have previously failed or were intolerant to conventional therapy (corticosteroids and/or immunomodulators, such as azathioprine, 6-mercaptopurine, or methotrexate), as measured by clinical remission at one year.
Due to the failure of the respiratory system, many patients admitted to the Intensive Care Units (ICUs) require the institution of invasive mechanical ventilation (MV), aiming at maintaining gas exchange, reversing respiratory muscle fatigue, among other benefits. However, an artificial airway installation may be harmful because of its deleterious capacity to the mucociliary clearance mechanism, predisposing to the accumulation of secretions and consequent respiratory infections. Physiotherapy in patients critical for the purpose of preventing and treating these respiratory complications. In this way, they are techniques that aim at a reexpansion and removal of airborne secretions. An application of manual hyperinflation with the Ambú (HM), applied through compression of the resuscitator (Ambu), an application of hypertension for the use of energy, pulmonary volume. Similar to the goal of manual hyperinflation, a hyperinflation maneuver without mechanical ventilator (HVM) is also widely used and has been shown to be effective. A maneuvering visa re-expansion of collapsed lung areas and increased peak expiratory flow, resulting in the mobilization of secretions. It is known that these techniques can cause deleterious effects to the lungs due to the high volumes administered and the variation in airway depression, predisposing to barotrauma and volutrauma, increasing the lung permeability and consequent pulmonary edema. There may also be a more subtle form of injury, such as a release of lung mediators, initiating a process of local inflammation. This biological response is called biotrauma, and if these mediators translocate into the systemic circulation, it can lead to dysfunction and death. The aim of the present study was to evaluate the biomarkers of pulmonary lesion in the hyperinflation maneuver with mechanical ventilator versus manual hyperinflation with environments in sudden patients under mechanical ventilation.
This study has quantified the hand strength in movements of handgrip and pinch with electronic dynamometer.
Heart failure (HF) has been associated with chronic deleterious effects on skeletal muscle, endocrine system, vasculature and sympathetic nervous system. These alterations have a significant impact on quality of life, leading to a reduction in functional capacity and limited symptoms, which involve dyspnea and fatigue. The investigators tested the hypothesis that hormonal anabolic deficiency associated with neurovascular alterations may worsen the prognosis of patients with heart failure.
This study aim evaluates the effect of Kinesio Taping (KT) on back muscle fatigue of low back pain patients, analysing the electromyography activity of longissimus muscle (median frequency) and the sustained time during a fatigue test (Ito test).
This is a randomized clinical trial designed to assess the 1-year effectiveness of two treatment modalities for the mandibular edentulists: conventional complete dentures and single-implant mandibular overdenture.
Both aging and other factors associated with it may contribute to the development of sarcopenia, such as lack of physical activity, inadequate food intake, hormonal changes and age-related increases in cytokine levels. What is a growing number of elderly people in Brazil and the world, it is extremely important to conduct research in order to know the mechanisms of action of new strategies to combat sarcopenia. Supplementation with omega-3 fatty acids is a promising intervention in sarcopenic rest. However, there is a practice of studies confirming the effects of omega-3 fatty acid supplementation on neuromuscular function in the elderly.
The aim of this study was to evaluate the effect of two different treatment agents used in conjunction with subepithelial connective graft technique on root coverage outcomes in multiple recession defects. Half of patients will receive root treatment with antimicrobial photodynamic therapy and the other half will receive photobiomodulation therapy by laser on surgery site.
