There are about 9876 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.
Regular physical activity (PA) promotes benefits for both physical and mental health. Among the numerous PA's with a collective nature that can add to the existing recommendations, combat sports training interventions are viable alternatives since they integrate benefits in different aspects for health. In this way, capoeira can be a strategy for the prescription of exercise, aiming to serve participants collectively and maintaining the adherence of this practitioner to the intervention. However, little is known about this issue. So, the aim of the present study is to verify the effect of 12 weeks of capoeira training on the physical performance and psychological aspects of previously physically inactive adults.
The study aims to evaluate the impact of different dietary interventions on abdominal fat components and cardiometabolic parameters. This is a randomized clinical trial study conducted in overweight adults, selected by voluntary adherence, in an outpatient clinic of a cardiology hospital. The sample was calculated based on data from a study with the Brazilian population, with the sample size calculated as a function of a mean difference (d) in visceral adipose tissue (VAT) after the interventions, standard deviation (s) and a significance level of 5% (z). To correct eventual losses, the number was increased by 20%. Four dietary interventions will be applied in the 6-month period: group with calorie restriction and balanced distribution of macronutrients (group 1); group with calorie restriction and low-carbohydrate diet (group 2); group with calorie restriction and low-fat diet (group 3) and group with collective nutritional guidance (group 4). Patients will be followed up monthly to assess weight loss, analyze adherence to the diet therapy plan, reinforce nutritional guidelines and monitor anthropometric measurements and abdominal adipose tissue. The evaluation of VAT and subcutaneous adipose tissue (SAT) by ultrasonography will be performed at baseline and after 6 months of intervention. The present study is expected to clarify the effects that different dietary interventions produce over 6 months on abdominal fat deposits and cardiometabolic parameters.
The main goal of this pragmatic clinical trial is to investigate the effects of trans-spinal tDCS in individuals with spinocerebellar ataxia (SCA) over some parameters of gait and postural control in real-world conditions, reflecting daily clinical practice. The main questions it aims to answer are: - If an extended number of tDCS sessions, beyond the typical 5 to 10 sessions described in scientific literature, applied concomitantly with exercises with progressive challenges, to yield positive outcomes over some parameters of gait and postural control in individuals with SCA and if there is retention of possible benefits one month later the end of this protocol. - If there is specific characteristics (including balance, gait, mobility, severity of ataxia, DNA test characteristics and non-ataxic signs) in individuals with SCA that can predict their improvement in postural control and gait following the 20 tDCS sessions. - Participants will receive 20 tDCS sessions concomitantly with exercises for gait and postural control with progressive challenges. - Postural control and gait of the participants will be assessed in two big sessions before (#assessment 1) and after the 20 sessions (#assessment 5) and 3 small sessions after every 5 sessions (#assessments 2, 3 and 4). Also, as a follow-up, they will be assessed a month after the end of the intervention (#assessment 6).
This is a single-center, non-interventional, retrospective study of data, at the level of the individual without identification, extracted from medical records of adult patients undergoing a kidney transplant procedure after 1st from January 2018 until reaching the sample size enrollment (around 500 individuals); this refers to the period of verification of individuals' eligibility for entry into the study. Individuals under strategy preemptive patients who developed CMV infection/disease within 12 months after transplantation. The data will be collected from date of transplant (including pre-transplant clinical history) until completion of at least 12 months after transplantation, or until graft loss, or recipient death or loss to follow-up, when/if applicable.
The objective of this randomized controlled, prospective clinical study, composed of 5 groups, G1, G2, G3, G4 and G5 is [Evaluate the intestinal microbiota profile, nutritional, immunological status and inflammatory profile, before and after total or partial removal surgery (gastrectomies) for gastric cancer, in a patient using probiotic supplements.] The main questions it aims to answer are: - probiotics are capable of modulating the immune response and microbiota in cancer patients who will undergo surgery - surgery itself alters the immunological pattern and microbiota of cancer patients Participants will be divided into groups for evaluation and the G1 intervention group will take probiotic capsules. The researchers will compare groups G1, G2 with G3 (negative control group) to see if there are differences between using probiotics or not, in controlling the immune response and if there are significant changes in their intestinal microbiota. Groups G4 and G5 will also be compared, where in these we will only measure the power of the use of probiotics in reducing surgical complications in the postoperative period.
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.
Hematological neoplasms originate from the differentiation and proliferation of abnormal lymphatic or myeloid cells that alter the constitution of elements of the blood, bone marrow and lymph nodes. Treatment includes high-dose chemotherapy alone or associated with hematopoietic stem cell transplantation (HSCT). However, the adverse effects of this treatment affect multiple organs and systems, reducing physical capacity, increasing the feeling of fatigue, anxiety and depression, which together affect quality of life. Patients who exercise before, during or after anti-neoplastic treatment demonstrate significant benefits. But rehabilitating physical capacity involves the challenge of fluctuations in the patient's readiness along with daily clinical variations, which ultimately directly affects the rate of adherence to exercises, impacting the effectiveness of the physical rehabilitation program. There is no specific individualization of muscular overload that takes into account such variability in pathophysiological, functional and psychological situations, but the cardiorespiratory response and muscular strength performance in the face of progressive overload can be measured with sufficient recovery periods to optimize the physiological adaptations promoted by muscular overload. regularly, even in patients undergoing antineoplastic treatment. Objective: To evaluate the adherence rate, operational feasibility, clinical/behavioral evolution and effectiveness of three different muscle overload models (aerobic, anaerobic and mixed) used for the physical rehabilitation of patients hospitalized for antineoplastic hematological treatment with HSCT
The objective of this study is to assess whether pre-anesthetic photobiomodulation (PBM) can effectively reduce needle puncture pain and enhance the efficiency of local anesthesia. In this double-blind randomized controlled trial, 50 participants were included. The control group underwent the standard anesthetic procedure, while the experimental group received the application of an infrared laser (100mW at 808nm, 8J at a single point) immediately before anesthesia, at the site of the intended needle puncture. Both groups underwent the same anesthetic procedure, administered by the same operator. The outcome evaluator and the patient were blind to the FBM application. The primary outcome of the study focused on pain experienced at the time of needle insertion, assessed using the Visual Analogue Scale (VAS) during the needle's introduction. Secondary outcomes encompassed anxiety levels, measured using the Beck questionnaire, anesthetic onset time determined through the electric pulp test, the number of anesthetics required for the procedure, and the necessity for supplementary anesthesia.
Despite many advances in prosthesis development, there are still some areas that need to be improved. One of them is the weight of the devices which could cause muscular fatigue in long-term use of the prosthesis and even abandonment. This study aims to identify the desired improvements in prosthetic devices from the perspective of the users, therapists, and relatives. That would be done through two kinds of questionnaires about technology acceptance.
This study will collect medical and background information from participants with diseases that affect the heart and blood vessels (cardiovascular disease). Participants will continue their normal care and will not get any treatment other than those the study doctor has prescribed.
