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.
Dysfunctional breathing and persistent hypocapnia can be associated with many of the symptoms experienced by patients such as dyspnea, fatigue, chest pain and palpitations. The identification of dysfunctional breathing and hypocapnia in these patients is important as it may represent a target for treatment. In many of these patients, tachypnea at low levels of exertion suggests increased respiratory muscle activity, which can lead to the sensation of dyspnea. Sympathetic hyperactivity leads to excessive and irregular ventilation during exercise. In this way, inspiratory muscle training can improve symptoms (dysfunctional breathing), possibly by attenuating the metaboreflex (vagal modulation-attenuation of the sympathetic response) of the inspiratory muscle in post-covid-19 subjects, reducing ventilatory variability.
The purpose of this study is to evaluate efficacy and safety of Dato-DXd in combination with rilvegostomig or rilvegostomig monotherapy compared with pembrolizumab monotherapy as a first line therapy in participants with locally advanced or metastatic non-squamous NSCLC with high PD-L1 expression (TC ≥ 50%) and without actionable genomic alterations.
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
Patients with low cardiac output syndrome requiring surgical and periodontal dental treatment will be selected to undergo the dental procedure using local dental anesthetic: 2% lidocaine with epinephrine and 2% lidocaine without vasoconstrictor. Cardiovascular events and the safety of using two cartridges (3.6 mL) will be evaluated. They will be evaluated by Holter monitoring in the period of 1 hour before, during and 1 hour after the procedure and blood pressure correction will be performed
A randomized clinical trial using oral letrozole 10mg/day for 7 days, for treating early cases of ectopic pregnancy, compared to intramuscular methotrexate
The purpose of the study is to evaluate the efficacy, safety and tolerability of balcinrenone/dapagliflozin compared with dapagliflozin alone on patients with chronic kidney disease (CKD) and albuminuria. This study will evaluate the effect of the balcinrenone/dapagliflozin on urinary albumin-to-creatinine ratio (UACR), compared with dapagliflozin in patients with CKD. This is a dose-finding study aiming to identify an optimal dose of balcinrenone/dapagliflozin for a future Phase III study in patients with CKD.
According to the World Health Organization (WHO), as of mid-September 2022, more than 21 million Brazilians have recovered from COVID-19. However, post-infection symptoms continue to appear months after the end of the acute infection, a syndrome called long COVID. Therefore, the aim of this study is to investigate the responses of fascia-focused manual therapy in participants with long COVID.
The objective of the study is to evaluate the effect of an 8-week online mindfulness-based meditation program on quality sleep status of undergraduate students medicine in the city of Passo Fundo/RS and Chapecó/SC In addition to sleep quality, secondary outcomes such as mindfulness, symptoms of depression, stress, anxiety and burnout will also be assessed
The study proposes a planned, double-blind, non-inferiority clinical trial involving patients with febrile neutropenia and risk of extended-spectrum beta-lactamase (ESBL) infection. The goal is: - Analyze the efficacy and tolerability of Ceftolozane/tazobactam (CEF/TAZ) compared to the current standard of care (meropenem) in patients with febrile neutropenia and risk of ESBL infection. Patients will be randomly assigned to receive CEF/TAZ or meropenem, with assessment of clinical response, toxicity and microbiological evolution. Stool samples will be collected before, during and after treatment for intestinal microbiota analysis and intestinal microbiome analysis to evaluate possible effects on GVHD. Analysis of the results will include the taxonomic classification of the organisms present. Data will be analyzed to assess non-inferiority in clinical response, incidence of GVHD, antimicrobial resistance and other outcomes.
After thoracic surgical intervention, patients often feel intense pain with respiratory movements reduction making coughing less effective. The air stacking improves peak of expiratory flow (PEF) and cough peak flow (CPF) in neuro myopathies, thus raising the hypothesis that may also be effective in patients undergoing thoracic surgeries. Objectives: To evaluate the effectiveness, safety and feasibility of air stacking on postoperative PEF and CPF in patients undergoing thoracic surgeries. Methods: Patients undergoing thoracic surgery underwent air stacking on 3th PO. Dyspnea, pain, SpO2, maximum inspirational pressure (MIP), maximum expiratory pressure (MEP), PEF and CPF were evaluated in pre and postoperatory.
