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 control of biofilm around implants is critical to the success of the implant rehabilitation of edentulous jaw with overdentures, and it is the dentist's duty to inform and guide patients, and keep their maintenance in order to prevent pathological processes that can lead to the implanted component loss.The aim of the present retrospective longitudinal study was to evaluate through clinical periodontal parameters and radiographic images in dental implants rehabilitated with overdentures installed seven years ago. individuals who underwent the installation of dental implants for making full implant-supported upper and lower mucus dentures in the Department of Implant Dentistry, Faculty of Dentistry, University of Santo Amaro, São Paulo, Brazil, in 2007. The periodontal parameters such as probing depth, plaque index, bleeding index and mobility as well as radiographic examination, are key to determine the correct diagnosis in dental implants. The control of biofilm around the implants seems to be a decisive factor for maintaining tissue health. We believe that the maintenance appointments are fundamental, but more studies should be conducted to elucidate microbial and immunological factors in implants placed and due for some time.
The purpose of this study is to evaluate the safety and efficacy of long-term dosing with ALN-TTR02 (patisiran) in participants with transthyretin (TTR) mediated amyloidosis (ATTR).
Bronchiectasis is characterized pathologically by the abnormal and permanent dilation of bronchi caused mainly by the perpetuation of inflammation and impaired clearance of secretions. Physical therapy is essential in the treatment of these patients, using its various techniques and devices. The aim of this study is to evaluate the impedance of the respiratory system, by impulse oscillometry, after breathing exercises with chest compression or flutter in patients with bronchiectasis, considering that there are no results in the literature on the effect of these techniques in the small airways of these patients.
This is a prospective and observational study to evaluate oncologic patients that presented upper gastrointestinal bleeding with the use of some prognostic scores.
Magnesium sulfate has been reported to improve postoperative pain, but evidence is still controversial. Some studies demonstrated benefits while others concluded that there is no efficacy. Aim: the aim of the study was to compare the effect of intravenous infusion of magnesium sulfate to ketorolac during laparoscopic gynecologic oncology surgeries. Methods: We designed a double-blind randomized controlled trial that compared intravenous magnesium sulfate to ketorolac and saline solution in postoperative pain, morphine consumption and opioid related side effects.
This multicenter prospective observational study will evaluate the quality of life in participants with rheumatoid arthritis (RA) who are initiated with rituximab (MabThera/Rituxan). Participants will be followed for 6 months from initiation of treatment.
The purpose of this study is to evaluate whether gut microbiota modulation by probiotic and symbiotic contribute with weight loss and improvement of metabolic parameters in women with obesity.
Objective: Compare venous occlusion rates at a one-year follow-up comparing 1920-nm versus 1470-nm laser treatment. Design: Non-randomized prospective study. Methods: Adult patients with varicose veins associated with great saphenous reflux were included. Procedures were performed between February and April of 2013. The 1470-nm laser ablation was performed in continuous mode, power being set between 8 and 10 W, while for the 1920-nm it was set between 5 and 6 W. Checking for vein closure was performed during the thermal ablation procedure, LEED (linear endovenous energy density) being calculated after the procedure. Follow-up data were collected at the 7-day, 30-day, 3-month, 6-month and 1-year visits, and involved clinical and ultrasound evaluation, measurement of occlusion extent.
Prospective, single center, randomized and non-inferiority study, to include up to 60 patients with de novo coronary artery disease. Patients will be followed at 30 days, 3, 6 and 12 months. At 3 months all patients will be submitted to angiographic and OCT evaluation.
The purpose of this study is to determine if abatacept is effective in the treatment of early rheumatoid arthritis.
