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.
This is a natural history study for children up to 18 years of age who have been diagnosed with Mucopolysaccharidosis Type IIIB (MPS IIIB, also known as Sanfilippo Syndrome Type B). Mucopolysaccharidosis type IIIB is a severe neurodegenerative disorder. The information gathered from this trial may help inform the design and interpretation of subsequent interventional studies. No clinical intervention or study drug is provided by Allievex in this study.
The Health and Education Ministries of Brazil launched the Health in School Program - PSE - in 2007. The purpose of the PSE is twofold: articulate the actions of the education and health systems to identify risk factors and prevent them; and promote the education for health in the public elementary school system. In the health field, the self-regulation (SR) construct can contribute to the understanding of life habits which can affect the improvement of individuals' health. This study aims to present a school-based program, Promotion of Self-Regulation in Health (SRH), which adds the self-regulation approach to the topics of healthy eating and oral health of the PSE for elementary school. A study of a randomized clinical trial enrolling the 5th grade students of public elementary schools from the south of Brazil is presented. The study has two phases. In Phase 1, teachers and health professionals will participate in a training program on SRH, and in Phase 2, they will conduct an intervention in class: Promotion of SRH. The participants were randomly assigned into three groups: Condition I followed the PSE program, Condition II group followed the PSE and the SRH program, and the control group did not enroll in either of the health promotion programs. For the evaluation of the study, the following measures and instruments were applied: Body Mass Index (BMI), Simplified Oral Hygiene Index (OHI-S), Previous Day Food Questionnaire (PFDQ), Declarative Knowledge for Health Instrument, Food Preference Instrument, Student´s Attitudes and Perceptions and Parents Perceptions and Influences on the Health Instrument, Food Availability and Oral Health Instrument, Self-Regulation for Health Scale, Self-Efficacy for Health Scale. Students in the three groups will be assessed five times throughout the year: before the beginning of the intervention program, three months into intervention, six months into intervention, at the end of the intervention, and, finally, six months post intervention to check for the impact of the program on children health.
The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The primary study hypotheses are that: - Neoadjuvant and adjuvant pembrolizumab plus chemotherapy, followed by adjuvant pembrolizumab is superior to neoadjuvant and adjuvant placebo plus chemotherapy, followed by adjuvant placebo in terms of Event-free Survival (EFS) based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), and - Neoadjuvant pembrolizumab plus chemotherapy is superior to neoadjuvant placebo plus chemotherapy in terms of rate of Pathological Complete Response (pathCR) at the time of surgery. With Amendment 10, upon study completion, participants will be discontinued and may be enrolled in an extension study.
The primary hypothesis of ROMA is that in patients undergoing primary isolated non-emergent coronary artery bypass surgery (CABG), the use of two or more arterial grafts compared to a single arterial graft is associated with a reduction in the composite outcome of death from any cause, any stroke, post discharge myocardial infarction and/or repeat revascularization. The secondary hypothesis is that in patients undergoing primary isolated non-emergent CABG, the use of two or more arterial grafts compared to a single arterial graft is associated with improved survival. Prospective event-driven unblinded randomized multicenter trial of at least 4,300 subjects enrolled in at least 25 international centers. Patients will be randomized to a single arterial graft (SAG) or multiple arterial grafts (MAG). Patients will be randomized in a 1:1 fashion between the two groups. Permuted block randomization with random blocks stratified by the center and the type of second arterial graft will be used to provide treatment distribution in equal proportion.
The purpose of this study is to determine whether Nivolumab, Ipilimumab combined with chemotherapy is more effective than chemotherapy by itself when treating stage IV NSCLC as the first treatment given for the disease
The use of opioids facilitates angiogenesis and has a proven action in the immune system, mainly in the reduction of natural killer cell activity, favoring the migration of neoplastic cells and inhibiting humoral and cellular immunity. These factors may contribute to recurrence and tumor metastasis. Therefore, could opioid-free anesthesia help reduce tumor recurrence? This is a prospective randomized controlled clinical trial in which patients undergoing radical prostatectomy will be evaluated by conventional means, which have moderate and high D'Amico criteria for tumor recurrence. In the operating room, patients will be monitored, receive peripheral venoclysis and then randomized into two groups: in group I, the anesthetic induction will be done with pre oxygenation with 100% O2, propofol, cisatracurium, lidocaine and fentanyl; In group II the induction will be done with the same doses of propofol, cisatracurium, lidocaine and placebo. In both groups maintenance of general anesthesia will be with propofol 1% target infusion controlled with model of Marsh target-controlled infusion plasma between 2.0 and 3.0 mcg / ml, ketamine, lidocaine and dexmedetomidine. Both groups will receive blockade of the transverse plane of the ultrasound guided ultrasound, group I with placebo (saline 0.9% 20 ml on each side) and group II with ropivacaine 0.375% 20 ml on each side. And the postoperative analgesia will be based on anti-inflammatory and opioid analgesics (pca of morphine) according to the analgesic pain scale of the patients. In the postoperative period, patients will be followed up for 2 years with serial doses of prostate specific antigen (PSA) to diagnose tumor recurrence (2 PSA measures> 0.2 ng / ml) and will be evaluated in relation to analgesia, need for analgesia of Rescue with morphine, satisfaction with the anesthetic technique, adverse effects (nausea and vomiting). The primary objective is to evaluate tumor biochemical recurrence after radical prostatectomy in patients undergoing opioid anesthesia compared to patients anesthetized without opioids. The secondary objectives are to evaluate the quality of analgesia with the two techniques, patient satisfaction with perioperative period, quality of anesthetic recovery and adverse effects (nausea and vomiting, pruritus and drowsiness). Thus, to answer the hypothesis raised, 146 patients will be needed (73 in each group).
In the current scientific literature, it is clear that SUI can cause several social, hygienic and personal relationship problems. It has also been proven that this condition affects many more menopausal women than menacme, and this is believed to be due to the hypoestrogenism characteristic of this phase. On the other hand, weakness of the pelvic floor muscles (PFM) is also related to the genesis of SUI. The role of these muscles would be to keep the bladder neck elevated (above the pubic symphysis) during increases in abdominal pressure, and its weakness would lead to excessive lowering of the bladder neck at these times, leading to SUI due to bladder neck hypermobility. The conservative treatment of this condition, therefore, encompasses the strengthening of PFMs, which would avoid excessive descent of the bladder neck during increases in abdominal pressure, thereby reducing urinary loss. In the current literature there are studies proving the effectiveness of pelvic floor muscle training; however, in relation to the literature on abdominal hipopressive gymnastics, it is observed that the scientific evidence is still poor, however, the technique is still Widely spread through extension courses offered throughout Latin America, France and Spain; With regard to the comparison of these methods with respect to their clinical efficacy and the quality of life and patient satisfaction, there are no consistent studies, and this fact motivated us to carry out this study.
The purpose of this study is to evaluate the efficacy and safety of daratumumab plus cyclophosphamide, bortezomib and dexamethasone (CyBorD) compared with CyBorD alone in treatment of newly diagnosed amyloid light chain (AL) amyloidosis participants.
Physical activity plays an important role in the management of chronic low back pain (LBP). Engaging in an active lifestyle is associated with a better prognosis. Nevertheless, there is evidence to suggest that patients with chronic LBP are less likely to meet recommended physical activity levels. Furthermore, while exercise therapy has been endorsed by recent clinical practice guidelines, evidence from systematic reviews suggests that its effect on pain and disability are at best moderate and not sustained over time. A limitation of current exercises programs for chronic LBP is that these programs are not designed to change patient's behaviour toward an active lifestyle. Therefore, the objective of this study is to investigate the short and long-term efficacy of a multimodal intervention consisting of supervised exercises, health coaching and use of an activity monitor (i.e. Fitbit Flex) compared to supervised exercises plus sham coaching and a sham activity monitor on physical activity levels, pain intensity and disability in patients with chronic nonspecific LBP.
In this study the investigators will evaluate the effects of yoga practice on multiple sclerosis patients and healthy controls for fatigue, quality of life, movement, cognition, brain activity, self-efficacy, stress, anxiety, depression, affective states and immunological response. To investigate the effects of yoga training delivered by a yoga instructor or through a smartphone application, the investigators will use a multidimensional approach that comprises of: evaluation of neuropsychological, quality of life and affective aspects, structural and functional magnetic resonance imaging, functional near infrared spectroscopy (fNIRS) combined with movement analysis (gait, strength, balance etc.) and analysis of the immune response.
