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.
Randomized, double-blinded, cross-over and placebo controlled clinical trial to evaluate the association between genetic polymorphism of CYP4F2 with cardiovascular adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs). Two groups were included according the CYP4F2 V433M genetic polymorphism (control - MM, N=7 vs. VV or VM variants, N=13). According the sample size planned, a mean difference of total body water delta between groups (control vs. polymorphic) of at least allow 10% could be observed.
The aim of this study was to analyze the effects of resistance exercise and training on cardiovascular function of peripheral artery disease patients.
Atraumatic Restorative Treatment (ART) is an alternative restorative technique for dental caries, applying the partial caries tissue removal philosophy using hand instruments, relative cotton rolls isolation, immediate restoration with Glass Ionomer Cements (GIC) and avoiding local anesthesia. The chosen material for this study will be the High Viscosity Glass Ionomer Cement (HVGIC) due to its unique physical-chemical properties as well as its applicability in challenging clinical situations where other materials would not be adequate. Although there are substantial evidences regarding GIC properties, information about GIC (with different costs) longevity is still weak. Therefore, the objective of this study is to assess the effectiveness of ART restorations performed with low-cost HVGIC in cavitated dentine carious lesions in primary and permanent molars. This will be a multicenter randomized controlled double-blind (patient and operator) clinical trial performed with 680 primary and/or permanent molars in children between 4 and 9 years old presenting cavitated dentine carious lesions in occlusal and occlusal-proximal surfaces. The tooth will be considered as the unit sample, which will be randomly allocated to the groups through a generated random list numbers and distributed in dark sealed envelopes opened only by dental assistants. Teeth in the test group will be submitted to restorative treatment with HVGIC Vitro Molar and those in the control group with HVGIC Fuji IX. The restoration effectiveness will be assessed by means of both clinical and bitewing x-rays control after 6 and 12 months.
This study aims to determine if a cow's milk-based formula with added nutrients has an effect on memory, reaction time, strategy or other cognitive development indicators in children 4-5 years of age.
The recent increase in obesity has led to an increase in the need for bariatric surgery. In this group of patients the postoperative pain management is of vital importance. One strategy to improve postoperative analgesia is the use of intraoperative methadone, specially in those patients which regional anesthesia is not feasible. There is evidence that the use of intraoperative methadone can lead to a analgesia lasting 24 to 36 hours, while not associated with increased side effects when compared to other opioids with short or intermediate duration of action. In this study the investigators will evaluate the efficacy of intraoperative methadone in reducing postoperative pain and opioid consumption.
The gold standard for the treatment of gingival recession, is the coronal repositioning of the flap associated with the subepithelial connective tissue graft. The acellular dermal matrix (ADM) has been used as a substitute a subepithelial connective tissue graft in periodontal plastic surgery and mucogengivais, and has achieved similar results. The use of ADM has the advantage of avoiding possible pre and postoperative complications, as well as overcome the limitations presented by autograft. The different surgical techniques used for root coverage seek predictability and success. For this, besides the type of incision placements flap and graft are of utmost importance because the healing benefit and outcome. The aim of this study is to compare two surgical techniques for root coverage and evaluate which one provides better cosmetic results and less morbidity . 20 adults , nonsmoking patients , showing multiple bilateral gingival recessions , class I or II Miller located in canine, first and second premolars are selected. Both techniques use the ADM as a graft. However , in one Quadrant partial flap will be held together with relaxing incisions through an incision intrasucular , ADM will be positioned 1 mm apical to the cementoenamel junction (CEJ) and the flap will be positioned 1 mm coronal CEJ. In the opposite quadrant a minimally invasive technique periosteal envelope above does not use relaxing incisions , preserves the buds will be held , as well as avoiding any scars, the graft will be used to ADM. The clinical parameters (probing depth, clinical attachment level, bleeding on probing index, height and width of the gingival retraction and height and thickness of keratinized gingiva) will be evaluated 2 weeks after the basic periodontal therapy and after 6 and 12 months to surgical procedures. In addition, measurements of photographic gingival recession with the aid of software will be performed.
Noninvasive assessment of VO2 during a single session of whole body vibration and changes in blood flow caused by the acute activity.
The purpose of the study is to describe: 1) the clinical profile, past and current management of participants with hepatitis C in Brazil reference centers; 2) the current situation about demographics characteristics, liver disease progression and clinical outcomes in Brazilian Hepatitis C virus (HCV) participants naive, in treatment and previously exposed to antiviral treatment without sustained virological response (SVR).
The aim of this study is to evaluate the visual function of patients with bilateral implantation of the IOL trifocal ZEISS AT LISA TRI AND TRI TORIC by means of visual acuity tests with and without optical correction, sensitivity curve contrast, defocus curve and quality questionnaire visual function (VFQ-25).
Women in the postmenopausal period suffer hormonal changes that contribute to a number of negative factors to health, such as reduced bone mineral density and loss of muscle mass, which contribute to the increased incidence of falls and consequent risk of fractures. Among the possibilities to alleviate these symptoms are mainly drug treatment and the systematic practice of physical exercise. Exercise stands out for not offering adverse effects. One form of exercise that has been recently investigated is the whole body vibration, another form of exercise well accepted by the population is the Pilates method. Taking into account the lack of literature on the benefits of vibration training; and also the Pilates method on bone mineral density, muscle strength, flexibility, postural balance, fear of falling and the quality of life of postmenopausal women, explains the importance of this work.
