There are about 9927 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 study is a retrospective study trying to find the predictive factors for medullary thyroid aggressiveness in terms of tumor metastasis and patients' survival.
This work aims to evaluate the effects of the association of green propolis extract with royal jelly on inflammation and oxidative stress in participants with chronic kidney diseases (CKD) and Systemic arterial hypertension (SAH), in a longitudinal, randomized, double-blind, placebo-controlled clinical trial that will be carried out for 2 months.
This is a retrospective observational cohort study. The clinical, pathological and treatment data of participants identified with adrenocortical carcinoma from the year 2000 onwards will be evaluated. Participants recruited for this study will be identified at the participating sites.
Rose Bengal Electromagnetic Activation with Green light for Infection Reduction II (REAGIR II) is a randomized, double-masked feasibility study. The purpose of this study is to determine differences in 6-month visual acuity between medical antimicrobial treatments alone versus antimicrobial treatment plus cross-linking with rose Bengal (RB-PDT). Patients presenting to one of the Aravind Eye Hospitals in India or to the Federal University of São Paulo ophthalmology clinic in Brazil with smear-positive and/or culture positive typical (I.e. non-Nocardia or Mycobacteria) bacterial corneal ulcers and moderate to severe vision loss, defined as Snellen visual acuity of 20/40 of worse, will be eligible for inclusion. Those who agree to participate will be randomized to one of two treatment groups: - Group 6, RB-PDT Plus Early Steroids: topical 0.5% moxifloxacin plus topical difluprednate 0.05% plus RB-PDT - Group 7, Sham RB-PDT Plus Early Steroids: topical 0.5% moxifloxacin plus topical difluprednate 0.05% plus sham RB-PDT
The objective of this study is to evaluate the efficacy, cosmetic acceptability and improvement of the stigmatization of the tested product (2039125 03) used bis in die (BID) for 3 months in adult patients suffering from mild to moderate melasma, or mild to moderate acne induced post-inflammatory hyperpigmentation, or solar lentigo.
The purpose of this study is to assess the safety and efficacy of the DTT106 in the treatment of erectile dysfunction associated with benign prostatic hyperplasia
This study aims to evaluate the effectiveness of neuromuscular electrical stimulation with superimposed voluntary contraction (NMES+ group) compared to NMES without voluntary contraction (NMES group) during the initial month of rehabilitation post anterior cruciate ligament reconstruction (ACLR). Forty patients will be randomly assigned to either the NMES group or the NMES+ group. Both groups will follow an identical rehabilitation regimen in the first month after surgery, which includes interventions for symptom management, inflammation control, edema reduction, improved joint motion range, and restoration of muscle function. All participants will undergo identical assessment protocols at four time points: pre-surgery evaluation, and assessments at 2, 15, and 30 days post-ACLR. The primary outcome of the study is the maximal isometric strength of knee extensors. Secondary outcomes encompass thigh muscle atrophy, self-reported functional impairments, knee pain, knee edema, joint range of motion, and quadriceps activation status.
Temporomandibular Disorders (TMD) are a collection of musculoskeletal disorders which affect the masticatory structures and have a multifactorial etiology. A biopsychosocial approach is recommended for the management of these disorders including different interventions like exercise, manual therapy and pain education. The aim of this study is to compare the effect of a condensed dosage pain neuroscience education program (2 initial sessions of 60 minutes) versus a fragmented dosage format (8 sessions of 15 minutes) combined with manual therapy and orofacial exercises on primary outcomes - pain intensity and disability - and secondary outcomes - pain-related self-efficacy, kinesiophobia, global perception of improvement, empathy, knowledge about pain neuroscience, beliefs about pain, exercise adherence, and catastrophizing - in patients with chronic painful TMD. This study will be a randomized controlled trial with a sample of 148 participants. Individuals will undergo a screening process to identify those with TMD diagnosis according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), aged 20 to 60 years, of both genders, and then the volunteers will be randomized into two groups (G1: Condensed dosage pain neuroscience education program + Manual therapy/orofacial and cervical exercises vs. G2: fragmented dosage pain neuroscience education program + Manual therapy/orofacial and cervical exercises). These volunteers will be recruited in the city of São Carlos, SP. The intervention will take place twice a week for 8 weeks, administered by a single therapist, each session lasting 1 hour. The primary outcomes will be pain intensity and disability, assessed using the numerical pain rating scale and the Craniofacial Pain and Disability Inventory (CFP-DI), respectively, and the secondary outcomes will be pain-related self-efficacy, kinesiophobia, global perception of improvement, empathy, knowledge about pain neuroscience, beliefs about pain, exercise adherence, and catastrophizing, assessed using the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD), Global Perceived Effect of Improvement scale, Pain Self-Efficacy Questionnaire (PSEQ), CARE Empathy Scale, and Pain Catastrophizing Scale (PCS). For statistical analysis, a mixed-model effect considering time and groups as factors will be used. A significance level of p<0.05 will be considered.
The goal of this study is to assess the safety and effectiveness of Dostarlimab compared to Placebo in adult participants with HNSCC (Head and Neck Squamous Cell Carcinoma)
This study aims to evaluate the effects of whole-body electrical stimulation (WB-EMS) in the rehabilitation of patients undergoing lung transplantation. This is a randomized clinical trial with patients from the inpatient unit of Dom Vicente Scherer Hospital of Irmandade Santa Casa de Misericórdia from Porto Alegre (ISCMPA) who will be allocated to a control group (which will receive physiotherapy from routine) or intervention group (which will receive physiotherapy from routine and WB-EMS). Interventions with WB-EMS will occur every day from the moment of extubation until hospital discharge (15 sessions per patient). Assessments will be carried out pre-lung transplantation, after extubation, during intervention protocols and at the time of hospital discharge.
