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.
Currently, there is no Brazilian or Latin American epidemiological data, such as clinical-pathological characteristics, standard treatments and outcomes of gastric cancer and pancreatic cancer in the region. The study aims to create a Latin American multicenter database to analyze epidemiological, clinical, and pathological data, treatments, outcomes, and biological information from patients with gastric and pancreatic cancer.
The primary objective of this study is to compare progression-free survival (PFS) in participants who receive sotorasib with platinum doublet chemotherapy versus participants who receive pembrolizumab with platinum doublet chemotherapy.
This study will evaluate the safety and efficacy of a new combination of 3 (three) antihypertensive drugs in a single pill (candesartan cilexetil 16mg + chlorthalidone 12.5mg + amlodipine 5mg) compared with another combination of 3 (three) antihypertensive drugs (Exforge HCT® [valsartan 160mg + hydrochlorothiazide 12.5mg + amlodipine 5mg]). This will be a non-inferiority trial and the primary outcome will be blood pressure control after 12 weeks of treatment.
The treatment of single gingival recessions comprises different well-established techniques, and the association between coronally advanced flap (CAF) and the subepithelial connective tissue graft is considered the gold standard. However, despite the excellent clinical results obtained, the use of subepithelial connective tissue graft is related to an increased risk of trans and postoperative bleeding, a longer duration of the surgical procedure and greater postoperative pain and morbidity. To overcome these limitations and increase patient acceptance, new biomaterials have been developed as possible alternatives to the use of connective tissue graft. Recently, tissue engineering has been investigating collagen matrices as carriers of biologically active substances. In vitro and in vivo studies have shown that the biofunctionalization of these matrices using injectable platelet rich-fibrin (i-PRF) can optimize the healing process of soft tissues using own's patient regenerative components. However, although it has promising potential, clinical studies evaluating the performance of functionalized collagen matrices are still scarce in the literature. Thus, the present study aims to evaluate the clinical, esthetic, patient-centered, immuno and microbiological results of the use of the biofunctionalized volume stable collagen matrix (VCMX) for the treatment of single gingival recessions RT1. For such purpose, a randomized controlled clinical trial of superiority, parallel and blind will be carried out. Seventy-five patients with RT1 single gingival recession will be selected, who will be randomly allocated to one of the following groups: CAF+VCMX+i-PRF (n = 25), coronally advanced flap associated with VCMX functionalized with i-PRF; CAF+VCMX (n=25), coronally advanced flap associated with VCMX; and CAF group (n = 25), coronally advanced flap alone (CAF). The groups will be compared regarding clinical, esthetic and patient-centered outcomes at the baseline, three and six months after the surgical procedure. The microbiological evaluation will be performed at baseline, three and six months after surgery and the concentration of inflammatory markers and growth factors will be assessed before the procedure and 3, 7, 14, 30 and 60 days after treatment.
Gingival recessions (GR) are often associated with non-carious cervical lesions (NCCL), resulting, thus, in a combined defect. This mucogingival condition has a different treatment prognosis when compared with a GR without wearing surface associated and frequently requires a surgical-restorative approach to achieve better esthetics and functional results. A limited number of clinical studies assessed different multidisciplinary protocols for the management of single combined defects and there is evidence that the use of dental materials does not harm the periodontal tissues and does not influence the root coverage obtained by means of subepithelial connective tissue graft (CTG). Although the association between coronally advanced flap (CAF) and CTG provides more predictable and stable outcomes in the long term, its use is related to some drawbacks. Different biomaterials have been developed to overcome these limitations as a possible alternative to autogenous graft. However, despite its potential, there is a lack of studies evaluating its use in treating this type of condition. Thus, this study aims to assess from a clinical and esthetics point of view and patient-centered outcomes, the use of a new collagen matrix (Geistlich Fibro-Gide®) associated with CAF for the management of single combined defects. For such purpose, 50 patients with single RT1 gingival recessions associated with NCCL will be enrolled and randomly allocated to one of the following groups: control group (n=25), partial restoration of cervical lesion and coronally advanced flap for root coverage (PR+CAF) and test group (n=25), partial restoration of cervical lesion and coronally advanced flap associated with volume stable collagen matrix (PR+CAF+VCMX). The two groups will be compared regarding the clinical parameters, among which bleeding on probing (BOP), biofilm accumulation (IP), clinical attachment level (CAL), recession reduction (RecRed), and the percentage of combined defect coverage (%CDC). Patient-reported outcomes such as post-surgery pain and discomfort, time to recover, the decrease of dentin hypersensitive, and aesthetics will be gathered. A professional assessment will be carried out regarding the aesthetic parameters. All these evaluations will be performed at the baseline and three and six months postoperatively.
The purpose of this study is to assess the effectiveness of nipocalimab when compared to placebo in decreasing the risk of fetal anemia (a condition in which a baby's red blood cell volume falls below normal levels while the baby is developing in the womb) with live neonates in pregnant participants at risk for severe hemolytic disease of the fetus and newborn.
The purpose of this study, is to clarify whether there is benefit from the perioperative use of HFNC in thoracic surgeries, from intubation to the postoperative period, evaluating hipoxemia during orotracheal intubation, immediate complications after intubation, mortality and in-hospital complications.
The goal of this trial is to test a debriefing protocol to improve non-technical skills (NTS) in medical students. The study aims to answer the following questions: - Does a debriefing intervention improve medical students' NTS? - Does the intervention have an impact on the students' performance in simulated scenarios? Participants in the study will be randomly assigned to one of the teams, each consisting of a trauma team leader and three assistants. The teams will rotate across four different scenarios, allowing participants to switch roles and act as team leaders. The intervention teams will be debriefed using the study protocol, while the control groups will receive standard technical feedback without focusing on NTS. The primary outcome measure will be the Non-Technical Skills for Surgeons (NOTSS) score, which is a validated assessment tool for NTS. Secondary outcome measures include the number of correct interventions performed in each scenario. The study will involve 40 medical students, and the sample size was determined based on previous studies and statistical considerations. A panel of health educators will define the debriefing protocol, and the trial has been approved by the McGill Research Ethics Board office. The study findings are expected to contribute significantly to the training of providers of trauma care for children worldwide. By exploring the impact of debriefing on NTS in pediatric trauma education, this project aims to fill a critical gap in current training models.
The goal of this study is to evaluate if hypertonic saline solution can prevent or attenuate acute kidney injury after heart transplantation in the early postoperative phase.
Introduction: Autism Spectrum Disorder (ASD) is characterized as a neurodevelopmental disorder, with motor symptoms that may predispose to falls and gait changes. Exercises through virtual reality (exergaming) showed good results in children with ASD, but no studies were found that evaluated the effects of exergaming on gait and the risk of falls. Objective: To evaluate the effects of exergaming on motor performance during gait and the risk of falls in children with ASD. Method: Pilot study of a clinical trial. There will be 22 participants, diagnosed with ASD, level I or II; age: 5 to 9 years old; that they do not use medications that interfere with postural balance and falls; without physiotherapy care for at least 2 months. They will be divided into Exergaming Group (EG, n=11) and Control Group (GC, n=11). The GC will receive guidance through booklets. The EG will be submitted to a treatment with exergaming for 3 months, with 2 weekly sessions of 45 min each (initial 10 min, 25-30 of exergaming with the Xbox360 console with Kinect sensor and game "Kinect Adventures!", 5 min of cool down ). They will be assessed using CARS-BR (Childhood Autism Rating Scale - Brazilian version), DCDQ (Developmental Coordination Disorder Questionnaire), EEP (Pediatric Equilibrium Scale), a semi-structured questionnaire to assess the history of falls and prevalence of falls, an adapted motivational scale for ASD, a satisfaction survey, and three-dimensional assessment of gait through the Gait Laboratory. Descriptive analysis will be performed and continuous variables will be summarized in mean and standard deviation, and categorical variables in absolute and relative frequencies. To compare the independent and paired variables, parametric tests will be used and a significance level of 5% will be considered (p <0.05). Pearson's correlation will be used to assess correlations between continuous variables and the Chi square test to assess the relationship between categorical variables. Expected results: It is expected that children from the EG will obtain better results than the CG on gait variables and the risk of falling, with clinical and statistical significance.
