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.
A clinical, multicenter, randomized, parallel-group, double-blind, double-dummy, comparative study of non-inferiority. ⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil).
The study consists of an open label trial designed to treat adult depression with TBS. Our aim is to build capacity in neuroimaging analyses by performing magnetic resonance imaging (MRI) assessments at baseline and after 7-10 days of treatment onset in 70 patients. The scientific goal is to test a hypothesis about treatment action: that TBS will reduce negative bias (which causally maintains negative mood) after 1 week of treatment, and patients who show this neurocognitive change will be the ones who go on to respond clinically after 6 weeks.
Among the different types of cancer that most affect children, leukemia is the principal. One of the main treatments for leukemia is chemotherapy. Among the most common side effects of chemotherapy are nausea and/or vomiting, diarrhea, fatigue, alopecia, neuropathy, opportunistic infections, and oral mucositis. It is still necessary to establish which microorganisms are predominant in the oral microbiota of children with leukemia, which factors influence it, what is its relationship with oral mucositis and what is their impact in the quality of life. To better understand the risks of secondary infection, it is important to develop preventive and/or therapeutic strategies to control the side effects of antineoplastic treatment in the mouth that may negatively impact the quality of life, to expose the risk of death as well as raise hospital costs for the care of children with leukemia. Objective: To identify the clinical characteristics of the oral condition, types of microorganisms of the oral microbiota, and quality of life in children/adolescents with acute lymphoid leukemia and acute myeloid leukemia before and during antineoplastic treatment, and compare them with healthy children/adolescent individuals. Methodology: Longitudinal, case-control study, with a convenience sample. The study group, composed of children/adolescent individuals who have a definitive diagnosis of acute lymphoid leukemia or acute myeloid leukemia. The control group, non-syndromic children/adolescents, with no history of cancer, matched by age and gender. The clinical condition of the mouth will be evaluated by means of indexes: dental caries index (dmft index), gingival index (GA), and simplified oral hygiene index. The assessment of the quality of life through the ohip-14 and POS-version14 quality of life questionnaire and microbiological evaluation of saliva through MALDI-TOF analysis. Statistical analysis will be performed through relative risk for cohort study with more than three paired groups. Odds ratio, for the control group more than three controlled groups and Mcnemere, for comparison with the control group, for more than three paired groups.
Chronic kidney disease (CKD) is a major public health problem worldwide, with a significant increase in the number of patients treated with dialysis and renal transplantation. Hemodialysis (HD) is the most widely used dialysis therapy in the world, and adequate vascular access is required. The central venous catheter (CVC), although not considered the ideal vascular access, is still widely used. Its use has a strong relation with access-related infection, whether it is an exit orifice (IES), a tunnel and the most severe, the bloodstream (BSI). Consequently CVC contributes to patients' morbidity and mortality in HD, as well as to the high cost of hemodialysis treatment. To compare the use of 0.1% topical gentamicin with the use of placebo in the exit site (ES) of tunneled catheters in patients in chronic HD regarding the reduction in IES and BSI rates and to identify the induction of bacterial resistance to gentamicin.
The present study aims to evaluate the effectiveness of Teleorientation in oral hygiene during Pandemic by COVID-19 in children aged 6 to 10 years, attended at the Pediatric Clinic of Forp. For this, a randomized clinical study will be carried out with the factor to be analyzed the comparison between synchronous and asynchronous teleorientation, the effectiveness of the transfer of knowledge in oral hygiene through video modeling and remote guidance. The response variables will be the assimilation of oral hygiene guidance through video modeling and synchronous guidance, the hypothesis is that educational content will have beneficial effects on children's oral health.
This research project aims to investigate the acute effects of a dance-based cardiac rehabilitation session in the cardiovascular system and autonomic modulation of women with cardiac risk factors. Also, as a secondary outcome, to compare the cardiovascular and autonomic responses of the dance-based session to a conventional exercise-based session.
A prospective and retrospective cohort study of patients with a documented pathogenic or likely pathogenic variants of TP53 were identified using blood DNA colection and breast cancer diagnosis by histological confirmation, between 1999 and 2022. All patients were followed by the Hereditary Group of a single cancer center (Instituto do Cancer do Estado de Sao Paulo). Patients were included if they had a histopathological diagnosis of localized invasive carcinoma or in situ carcinoma of the breast and with localized disease. Patients met Revised Chompret criteria, Li Fraumeni like syndrome,family member of carrier TP53 or hereditary breast and ovarian syndrome for germline test.
The purpose of this study is to investigate the efficacy and safety of mepolizumab in children and adolescents with hypereosinophilic syndrome (HES) who are receiving standard of care (SoC) therapy.
This study is conducted to test the hypothesis that patients with lung cancer undergoing treatment with immunotherapy, chemotherapy and tyrosine Kinase Inhibitors receiving a high protein diet and supplemented with fish oil will improve muscle mass, therapeutic response and modulate the intestinal microbiota within a 4 month period.
A Multicenter Retrospective Study to understand the clinical characteristics, treatment pathway and resource utilization for patients with chronic lymphocytic leukemia A retrospective, multi-centre, observational study to describe disease characteristics, treatment patterns, treatment-related outcomes, and resource utilization for Chronic Lymphocytic Leukemia (CLL) patients in multiple international regions
