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.
The primary objective of this study is to assess the efficacy of ALXN2220 in the treatment of adult participants with ATTR-CM by evaluating the difference between the ALXN2220 and placebo groups as assessed by the composite endpoint of all-cause mortality (ACM) and total cardiovascular (CV) clinical events.
Treatment clinical trial, randomized, controlled, parallel, double-blinded, with two groups, that aims to evaluate the best application strategy when using a flowable bulk fill composite (Opus Bulk Fill Flow APS, FGM, Brazil) in class II cavities. Volunteers will be selected and recruited, following inclusion criteria and pre-established exclusion criteria. All volunteers will be informed and sign a term of clarification and consent. 38 enrolled patients will receive 76 Class II dental restorations, made in two different ways, one from each experimental group. Authors will perform restorations with an incremental composite (Vittra APS - FGM) associated with a bulk-fill flowable composite (Opus Bulk Fill Flow APS - FGM), in class II cavities, exposing (Group BP) or not (Group IP) the bulk fill flowable composite to the cavosurface angle on the proximal wall of the restorations. In both groups, Opus Bulk Fill Flow APS resin will be used in the bulk technique with up to 5mm depth increments, leaving 1 mm in the occlusal for incremental Vittra APS composite resin. Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using FDI scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.
Even with a large number of agents with action desensitizing agents (which reduce the symptoms of tooth sensitivity) available in market, there is no treatment considered the gold standard, which is completely effective for treat sensitivity caused by tooth whitening treatment. In this sense, the Pregabalin (PG), a medication with analgesic and anti-inflammatory action, can be a effective alternative to control this discomfort. Therefore, the objective of this project is to evaluate the effect of applying a gel containing the 10% Pregabalin associated with in-office teeth whitening, in reducing sensitivity dental.
The use of a graft from the left internal thoracic artery to the left anterior descending artery has become the gold standard for the indication of coronary artery bypass grafting. However, choosing a graft for the second-best coronary artery, focusing on long-term patency, is still a challenge. The saphenous vein using the "no-touch" technique is an alternative to a radial artery graft, but there is little evidence, especially in women. This randomized clinical study aims to compare the patency of these grafts in the second-best coronary artery in women undergoing coronary artery bypass grafting.
The goal of this clinical trial is to compare the effectiveness of two hair removal techniques: Intense Pulsed Light (IPL) and Diode Laser in woman underarm. . Main Questions: - Determine the thread count in a 4cm² quadrant in the central axillary region before each session, 4-6 weeks after the last session and at follow-up 30 weeks after the last session; - Measure the thickness of the hair before each session, 4-6 weeks after the last session and at follow-up 6 months after the last session; - Compare the level of pain during procedures; - Evaluate the volunteer's level of satisfaction after the end of the sessions programmed by the study; - Evaluate quality of life and self-image before and after the end of the sessions programmed by the study; - Evaluate the maintenance of results 6 months after the last procedure performed. Researchers will compare IPL and Diode laser to see if hair removal is similar at short and long time course. The IPL treatment will be applied to one axilla. The 800nm Diode Laser treatment will be applied to the other axilla. Treatment allocation will be randomized for each participant. Participants will undergo monthly sessions for four months, totaling four treatments. Follow-up assessments will occur 30 days and 6 months after the final session.
This randomized clinical trial aimed to compare the clinical and microbiological effects of different times of administration of metronidazole (MTZ) and amoxicillin (AMX) in the treatment of periodontitis.
To investigate the safety and technical success of EUS-guided gastroenterostomy (EUS-GE) using the AXIOSTM lumen-apposing Metal Stent for the management of symptoms associated with gastric outlet obstruction from malignant unresectable neoplasm.
ABSTRACT- Introduction: Skills such as recognizing and managing emotions, developing empathy, building cooperative relationships, solving problems effectively and obtaining communication skills have gained importance in several schools and this has been made possible by Socio-Emotional Learning (SEL). Robust studies in this area in Latin America are lacking, and what happens in the brain and in our general physiology, from trainings related to SEL, needs to be better understood. Objectives: To assess the effects of Learning for Hearts and Minds Training (TACM) on positive and negative affect, empathy and compassion, emotional expression, self-compassion, life satisfaction, sense of community in the classroom, academic goals, school performance, brain activity and heart rate variability in 4th and 5th year elementary school students. Methods: This is a randomized controlled trial in clusters with cross-over, in approximately 600 students. By the end of the first semester, one group of students will receive the TACM and the other will be a waiting control group. In the second semester, the latter will receive the TACM and the former will continue the TACM practices. The groups will be evaluated in 5 moments during the year. A classroom will be randomly assigned to undergo an assessment of brain activity and cardiac variability to assess their ability to regulate emotions. Students, parents and teachers will be drawn for a qualitative interview at the end of the academic semesters about the effects of TACM.
Laser Ablation therapy (LA) using an 810nm diode laser and Indocyanine Green (ICG) solution, which efficiently absorbs laser energy and increases the effectiveness of tissue removal. Intracanal heating can potentially cause damage to structures outside the tooth root. The study was to observe possible changes in the periodontal ligament and cementum resulting outside the root using this treatment. Histological and morphological examination of extracted cementum, ligament, and collagen post-exposure showed no difference in these structures vs. non-treated controls.
The goal of this observational study was to assess the degree of agreement between the endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions in adult patients undergoing colonoscopy in Hospital Sírio-Libanes. The main questions it aimed to answer were: - The degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions by calculating the Kappa Value of agreement. - To establish the detection rate of sessile serrated lesions and adenomas in the Endoscopy Department at Hospital Sírio-Libanês. - To evaluate the degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions based on the resection method. - To assess the accuracy, positive predictive value, and negative predictive value of endoscopic diagnosis of serrated lesions compared to anatomopathological diagnosis. The data were prospectively collected through a form specifically designed for this project, that was completed immediately after the examination by the performing colonoscopist. All patients enrolled in this study agreed to participate in it and signed an informed consent form prior to the colonoscopy.
