There are about 6223 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.
To develop and validate a specific questionnaire of sexual quality of life in several languages and cultures (France, Brazil, Australia) allowing a meaningful and comprehensive assessment of the sexuality of patients infected with HIV and HCV; Propose reference scoring for sub-populations.
This study was designed to compare 3 immunosuppression regimens: sirolimus and tacrolimus versus everolimus and tacrolimus versus mycophenolate and tacrolimus. The primary outcome is the incidence of cytomegalovirus infection / disease, a relevant medical need in the absence of pharmacological prophylaxis.
Non-alcoholic Fatty Liver Disease (NAFLD) is characterized by excessive accumulation of lipids in hepatocytes, not associated with alcohol consumption and ranges from hepatic steatosis to steatohepatitis, a form that can progress to cirrhosis or hepatocarcinoma, and is considered a liver manifestation of the metabolic syndrome (MetS). The disease occurs in 16 - 30% of the general population, but can reach up to 90% of obese individuals. Changes in lifestyle, including weight loss and physical activity are indicated with first choices for improvement of the liver condition. Recently the relationship between obesity, diabetes, MetS and NAFLD with intestinal microbiota has also been suggested in the development and progression of liver disease, since it is related to hepatic steatosis and inflammation. In this sense, this work aims to evaluate the effects of probiotic supplementation on intestinal microbiota modulation, degree of hepatic fibrosis and steatosis, inflammation and body composition.
This study will be a controlled, randomized, parallel group trial where the survival rate of direct and indirect restorations on removable partial denture abutment teeth will be assessed. For this, individuals with widely destroyed teeth and need for endodontic treatment, with at least one remaining dentin wall, adjacent to edentulous spaces in Kennedy Classes I and II will be selected. After the minimum period of one year the teeth will be reassessed through clinical and radiographic examination annually. All patients will receive oral hygiene instructions, caries disease control and endodontic treatment according to the need of each case. Prior to post cementation, patients will receive endodontic treatment through routine techniques that include use of rubber dam, mechanized instrumentation with NaOCl 2%, gutta percha and endodontic cement filling and condensation by the McSpadden technique. The preparation for post space will be done with a specific bur compatible with the diameter of root canal, and the same preparation cast post and cores. The glass-fiber posts (will be cleaned with 70% alcohol and receive silane application. The clinical protocol for direct restoration and confection of the composite resin core will occur in the same way, using the same materials: the dental structure will be etched with 37% phosphoric acid and rinsed, followed by the adhesive system and fabrication of the restoration by incremental technique according to the manufacturer's recommendations. It is important to emphasize that the direct restorative procedure will be carried out in the same consultation of the glass-fiber post cementation. In order to make the cast metal cores, the indirect impression technique will be done with prefabricated pins associated with addition silicone. In this technique, the lightweight material will be inserted into root canal and then, the pin will be introduced into the canal. Next, a prefabricated tray with the heavy and light material will be positioned for removal of the assembly, being removed after the setting time determined by the manufacturer. The mold obtained will be sent to the dental technician for cast post and core fabrication. All posts will be cemented under rubber-dam isolation using self-adhesive resin cement. In teeth where randomization is a metalceramic crown, first the composite resin or metal core will be prepared with a 3216 drill, in order to obtain 1.5mm wear on the proximal and free faces and 2mm on the occlusal surface. The margin design in form of a chamfer, preferably at the gingival level whenever possible. The impression procedure will be carried out using a molding cap and polyether, which will be removed in a tray with irreversible hydrocolloid. A temporary crown will also be made for the patient. The metallic infrastructure will be tested in order to verify its adaptation and transferred in irreversible hydrocolloid molding for later ceramic application. After application of the ceramic, the laying and adaptation of the prosthetic piece will be conferred, being the crown luted with self-adhesive resin cement. Once the restoration / crown of the abutment tooth has been made, the treatment will continue with the preparation of the removable partial denture. The teeth will always be prepared in the mesial proximal area. The delivery of the removable partial denture will be considered the baseline of the study. At this moment, the necessary adjustments and subsequent control of the prosthesis will be made after 24, 72 hours, a week and 15 days in order to check for possible flaws. After 6 months and 1 year of delivery of the removable partial denture, all patients will be recalled for clinical and radiographic evaluation of prostheses / restorations and oral hygiene conditions. This monitoring will be conducted by two evaluators until the end of the trial. All clinical procedures will follow pre-established protocols and the data of each patient and intervention will be recorded in the individual patient file.
The purpose of this program is to evaluate the efficacy and safety of guselkumab in participants with Crohn's disease.
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).
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.
