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 randomized controlled pilot trial with the aim of identifying the dose of liposomal amphotericin B associated with the highest cure rate in Cutaneous Leishmaniasis (CL). We selected 28 patients of both sexes, aged 60 years or older, diagnosed with CL and confirmed by detection of L. braziliensis DNA. The groups were treated with different total doses of medication: G1: 12 mg/kg; G2: 18mg/kg; G3: 24 mg/kg. Clinical and laboratory evaluations were carried out during the period of 180 days (D0, D15, D30, D60, D120, D150 and D180).
Patients with chronic kidney disease suffer from uremic toxin accumulation. Treatments with hemodiafiltration demonstrate the highest capacity for removing solutes, as well as improving mortality. While exercise has been proven as an adjunct therapy in patients on maintenance hemodialysis, little is known about the exercise influence in maintenance hemodiafiltration programs. Methods: A retrospective observational study of chronic kidney disease patients at Fenix Nephrology group from 2021 until 2023. Patients were assessed at the start of the exercise program and after six months of rehabilitation. Physical tests included a step-test for endurance, handgrip and one-repetition maximum for muscle strength. The Kidney Disease Quality of Life Short Form evaluated patient-reported outcomes. Kt/V urea and urea reduction ratio were surrogates for hemodiafiltration adequacy. Patients carried out twice weekly aerobic exercises at 70% of the maximum heart rate during the step test, and resistance exercises at 60% of one-repetition maximum.
Breast cancer is the most common cancer in women globally, with 2.3 million new cases diagnosed in 2020. Hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) breast cancer is the most prevalent subtype, comprising 69% of all breast cancers in the USA. Within the tumor immune microenvironment, a higher intensity of myeloid cell infiltration and low levels of lymphocyte infiltration have been associated with worse outcomes. Markers in peripheral blood have emerged as predictive biomarkers that can be easily obtained non-invasively and at low cost. Experiments have confirmed the relative components of these tests (such as the immune cells) directly or indirectly participated in tumour occurrence, development, and immune escape, underscoring the potential use of laboratory tests as tumour biomarkers
The goal of this study is to measure the effect of telerehabilitation on the treatment of nonspecific chronic LBP in the adults Brazilian Black population. The main questions it aims to answer are: 1. Will the graded activity exercises guided by educational approach or only the educational approach alone improve low back pain intensity, functional capacity, quality of life, anxiety, fear-avoidance beliefs due to nonspecific chronic low back pain before, immediately after the 4-week intervention, and after 3 and 6 months of follow-up? 2. How will participants' behaviors in terms of frequency and adherence, exercise feedback diary, and educational approach for nonspecific chronic low back pain be? What are the participants' opinions and any difficulties or barriers encountered throughout the study? 3. What are the perceptions of discrimination based on race, gender, age, socioeconomic status, and education when accessing healthcare services for the treatment of low back pain in the past? Researchers will compare Group Experimental Graded Activity with Educational Program with Telerehabilitation to a placebo (only Educational Approach ) to see improve the pain intensity and functional capacity because of low back pain. Participants will: - Take Group Experimental (GAEP) or a placebo (OEA) 3 times per week, for 1 month. - Keep a feedback diary of their symptoms and the barriers they have. - Visit the researcher by online teleassessment after one month, 3 months and 6 months follow-up.
The objective of this study is to evaluate the effects of royal jelly on inflammation and cellular senescence in patients with chronic kidney disease (CKD) on hemodialysis (HD).
In a previous clinical trial in China and the United States (US), the investigators developed and validated a mobile, high-resolution microendoscope (mHRME) for screening and surveillance of esophageal squamous cell neoplasia (ESCN). The trial revealed higher specificity for qualitative (visual) interpretation by experts but not the novice and in the surveillance arm (100% vs. 19%, p <0.05). In the screening arm, diagnostic yield (neoplastic biopsies/total biopsies) increased 3.6 times (8 to 29%); 16% of patients were correctly spared any biopsy, and 18% had a change in clinical plan. In a pilot study in Brazil, the investigators tested a software-assisted mHRME with deep-learning software algorithms to aid in the detection of neoplastic images and determine the performance, efficiency, and impact of the AI-mHRME when to Lugol's chromoendoscopy (LCE) alone and when using AI-mHRME with LCE. In this clinical trial, the investigators will build on the Brazil pilot trial data to optimize an artificial intelligence (AI) mHRME and evaluate its clinical impact and implementation potential in ethnically and socioeconomically diverse populations in the US and Brazil.
Background. Treatment with intravenous iron has been shown to improve symptoms, functional capacity, and quality of life in patients with heart failure with reduced ejection fraction (HFrEF) and iron deficiency. However, the mechanisms underlying these beneficial effects remain unknown. SGLT2i seem to alter hematocrit and other hematological markers or iron content. This study aims to measure cardiac magnetic resonance changes in myocardial iron content and in left ventricular function after administration of intravenous iron with and without the concomitant use of SGLT2 inhibitor in patients with HFrEF and iron deficiency.
To develop and evaluate a pharmaceutical formula based on green banana peel extract for the treatment of stasis dermatitis.
The aim of this clinical trial is to evaluate photodynamic therapy and photobiomodulation in the periodontitis treatment. To evaluate the clinical and microbiological response of conventional periodontal treatment associated with photodynamic therapy and photobiomodulation with red or infrared laser. Participants will receive periodontal treatment carried out with the use 0.005% methylene blue and laser therapy (photodynamic therapy), associated with conventional periodontal treatment, as well as the use of photobiomodulation with red or infrared laser associated with conventional periodontal treatment in participants with periodontitis. So, twenty periodontitis patients will be selected and separated in two groups compared with placebo. Clinical and microbiological parameters will be evaluated at baseline and 3 months after periodontal treatment: plaque Index, bleeding on probe, probing depth, gingival recession and clinical attachment level.
The goal of this study is to explore the use of mid-infrared spectroscopy (ATR-FTIR) as a detection tool for endometriosis in urine.
