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.
Overall objective: To analyze the relationship of the physical activity practice measured directly with the autonomic cardiac modulation in adults. Specific objectives: i) to verify through the Baecke questionnaire whether the different domains of physical activity (work, leisure and occupational activities) are related in the same way to the autonomic cardiac modulation; ii) Analyze whether high blood pressure and resting heart rate values are related to poor cardiac autonomic modulation regardless of nutritional status.
The objective of this randomized and longitudinal clinical study is to compare the installation of immediate implants in the esthetic zone through computer-guided-surgery and conventional surgery. To this end, 22 patients who need implant-supported replacement on the anterior region of the maxilla will be selected and after extraction will receive: Guided surgery (GS): installation of dental implant with the aid of the virtually planned guide by means of specific software; Conventional surgery (CS): installation of dental implant performed freehand using a conventional surgical guide made by study models.
The digestive process begins in the mouth and follows in the stomach and intestine. In the stomach the food is mixed with the gastric juices forming the chyme. To mix the food with the gastric juice as well as to provide gastric emptying (GE), the movements of the stomach are of great importance. Intestinal transit time is understood of the combination of GE, small intestine transit and colon transit time. The composition of the diet (lipid and protein content) exerts a direct influence on intestinal transit time due to the stimulation of hormone secretion, cholecystokinin and gastrin, respectively, which act to decrease GE velocity. In this context, it is also observed an important influence of dietary fibers on the speed of GE. Despite all knowledge about dietary fibers, information on such compounds still has many controversies. Due to the difficulty of finding compounds that fit into only one specific category (viscous, fermentable or prebiotic) there is difficulty in establishing a concept that best defines what are dietary fibers. The CODEX Alimentarius Commission in 2009 defined dietary fibers as carbohydrate polymers composed of ten or more monomer units of this macronutrient, which are not hydrolyzed by enzymes in the human intestine. Dietary fibers can be classified into insoluble and soluble according to the ability to bind to water molecules and form gels. Soluble fibers, especially those classified as prebiotic, in the intestine are fermented by bacteria giving rise to short chain fatty acids (SCFA). The SCFA stimulates the production and secretion of PYY and GLP-1 are associated with inhibition of gastric motility. Due to the importance of knowing the intestinal transit time, several methods have been developed, but scintigraphy is the gold standard technique for this analysis. Given the above and controversies present in the literature on the dietary fibers, there was a shortage of studies with the objective of evaluating the impact of different dietary fibers in intestinal transit time. This study shows relevant to help elucidate the behavior of different dietary fibers in intestinal transit time, offering data for correct and safe use of dietary fibers in various clinical situations. The hypothesis of this study is that the partially hydrolyzed guar gum delays the time of gastric emptying and intestinal transit, being this effect not observed for fructooligosaccharide
The current study will compare pembrolizumab (MK-3475) plus maintenance olaparib, vs. pembrolizumab plus maintenance olaparib placebo for the treatment of squamous NSCLC. The study's 2 primary hypotheses are: 1. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance olaparib placebo with respect to progression-free survival (PFS) per RECIST 1.1 by blinded independent clinical review (BICR). 2. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance olaparib placebo with respect to overall survival (OS). As of Amendment 07, there will be no further analyses for OS and patient-reported outcome assessments.
The current study will compare pembrolizumab (MK-3475) plus maintenance olaparib, vs pembrolizumab plus maintenance pemetrexed for the treatment of nonsquamous NSCLC. The study's 2 primary hypotheses are: 1. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance pemetrexed with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) by blinded independent clinical review (BICR) and 2. Pembrolizumab plus maintenance olaparib is superior to pembrolizumab plus maintenance pemetrexed with respect to overall survival (OS).
The objective of this randomized controlled clinical study was to compare bone quality between three different alveolar ridge preservation methods, also with the evaluation of primary and secondary dental implant stabilities at these sites.
The reason for this study is to see if the study drug called baricitinib works and is safe in children and teenage participants with atopic dermatitis.
This study is a clinical trial aims investigate the effects of neurostimulation in the treatment of children with mild ASD, specifically the action of tDCS on social cognition skills. tDCS can modulate neuronal activity in patients with ASD. Specifically, this technique has shown to be a promising tool in the promotion of social neuroplasticity, aiming at more adaptive social interactions. In this sense, it was hypothesized that participants treated with active tDCS will present better performance in social cognition tests than those submitted to sessions with simulated current.
This is a multicenter, randomized, double-blinded, controlled Phase 3 trial of cabozantinib in combination with nivolumab and ipilimumab versus nivolumab and ipilimumab in combination with matched placebo. Approximately 840 eligible subjects with intermediate- or poor-risk advanced or metastatic RCC by IMDC criteria will be randomized in a 1:1 ratio at approximately 180 sites.
The aim of the HEM-POWR study is to understand better how Damoctocog alfa pegol (Jivi) is used to treat people with Hemophilia A in day-to-day life, how well the treatment is tolerated and how satisfied patients and physicians are with the treatment.
