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.
Fibromyalgia (FM) is a syndrome characterized by generalized musculoskeletal pain, fatigue, non-restorative sleep, cognitive changes, depressive and neurovegetative symptoms. It is known that conventional pharmacological therapies produce responses with little clinical impact in more than 50% of patients. Functional alterations of the motor cortex and its connections with subcortical structures have also been demonstrated in FM. Based on the above, the objective of this research is to identify subgroups of patients with greater potential for responsiveness to treatment with a view to advancing diagnosis and treatment. In this study, the therapeutic target will be transcranial direct current stimulation (tDCS) according to the potential of responsiveness to the placebo effect, with the precise location of the stimulation area by a neuronavigation system, with the objective of counter-regulating the dysfunctional processes responsible for triggering and maintaining FM symptoms. Therefore, this clinical trial aims to compare the efficacy of anodal tDCS applied to the left dorsolateral prefrontal cortex (DLPFC) compared to simulated tDCS in FM, according to susceptibility to placebo effect and serum endorphin levels.
This clinical trial aims to compare the effect of a nutritional intervention based on Mindful Eating, with standard dietary treatment, in changing the eating behavior of overweight individuals.
The purpose of this study is to evaluate the effectiveness of the use of artificial intelligence in home monitoring in patients with uncontrolled arterial hypertension.
Systemic Lupus Erythematosus (SLE) is an immune-mediated disease associated with inflammation of multiple organ systems. This study will assess how safe and effective upadacitinib is in treating adult participants with moderately to severely active SLE. Adverse events and change in the disease activity will be assessed. Upadacitinib is an approved drug for rheumatoid arthritis, psoriatic arthritis, and axial spondylarthritis and is being developed for the treatment of SLE. This study is "double-blinded", which means that neither the trial participants nor the study doctors will know who will be given upadacitinib and who will be given placebo (does not contain treatment drug) . This study comprised of 3 sub studies. In Study 1 and Study 2, study doctors put the participants in 1 of the 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. Eligible participants from Study 1 and Study 2 will enter Study 3 at week 52 to receive specific doses of upadacitinib based on their disease activity and their original treatment assignment in Study 1 or 2. Approximately 500 participants diagnosed with SLE will be enrolled in each of the Study 1 and Study 2 in approximately 320 sites across the world. Participants will receive oral tablets of upadacitinib or matching placebo once daily for 52 weeks in Study 1 and Study 2. Eligible participants from Study 1 and Study 2 will receive oral tablets of upadacitinib once daily for 52 weeks in Study 3. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
. 24 individuals were evaluated, with low back pain for more than 12 weeks and aged between 12 and 65 years. The current used in the lumbar region of the participants was of the tetrapolar interferential type and the stimulation mode was the automatic vector, carrier of 4,000 HZ, modulation frequency (AMF) of 50 HZ, sweep frequency of SWEEP of 20HZ. The assessment of pain and functionality was performed using the data collection instrument, the Visual Analogue Pain Scale (VAS), Rolland Morris Disability Questionnaire (RMDQ) and the Owestry Disability Questionnaire (ODQ) respectively. The present study demonstrates that treatment with interferential current promotes chemical improvement in participants, which opens up new perspectives on the use of this therapeutic approach.
The growing resistance of microorganisms to antimicrobials is a major threat to public health nowadays. Reducing the consumption of antibiotics is one of the main strategies to control this issue. Protocols using biomarkers to guide antimicrobial therapy have been studied, with promising results in safely reducing patient exposure to these drugs by reducing duration of treatments. Procalcitonin (PCT) and C-reactive protein (CRP) represent the most promising biomarkers in this context. Although less studied, CRP has the potential advantages of lower cost and wide availability when compared to PCT. However, decision algorithms involving biomarkers proposed in studies published so far are very far from daily medical practice in hospitals, mainly because there is poor accessibility to these protocols, and because most of them do not contemplate each patients clinical variables. The objective of this project is to evaluate the efficacy and safety of a multimodal protocol using clinical variables and the CRP value to guide antibiotic therapy in hospitalized patients. This protocol will be applied diretcly by the assistant medical teams through a digital clinical decision support tool available in the form of an application for mobile devices developed by the research team.
The purpose of this study is to assess the socio-demographic, disease-related and treatment-related characteristics, and the standard of care (SOC) treatment patterns of participants with major depressive disorder (MDD) with anhedonia with inadequate response to their current antidepressant treatments and treated according to the standard of care treatment.
Phase 1/2a Phase 1 is an open-label, multicenter dose escalation/dose expansion study designed to assess the safety, tolerability, pharmacokinetics (PK) and antitumor activity of IMX-110 in combination with Tislelizumab. The recommended Phase 2 dose (RP2D) will be evaluated in further dose expansion Phase 2a study submitted as an amendment to this Phase 1 protocol during the conduct of the Phase 1 study.
This controlled before-and-after study analyse the impact of thiamine supplementation on outcomes of patients with septic shock treated according to the surviving sepsis campaign 2021 guidelines
Proximal femoral fractures commonly occur above 50 years and regional anesthesia could be a complement in the perioperative treatment of the patients. The use of pericapsular nerve group block (PENG Block) has been proposed to reduce pain. However, no studies have explored the efficient of the systemic analgesia associated with PENG Block in functional limitation in the preoperative period. In this sense, the main goal of this study is to evaluate the effectiveness of systemic analgesia associated with PENG Block in patients with proximal femoral fractures in the period preceding the surgical procedure.
