There are about 9905 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.
Multicentric study on Chagas disease that seeks to evaluate a new treatment regimen using the drug benznidazole. Currently, existing treatment regimens are long and have frequent side effects, which leads to a high dropout rate among patients. The research proposes testing two shorter benznidazole regimens to see if they are as effective as standard treatment, but with fewer side effects. The study will have 672 participants and will be carried out in four locations, Bolivia and Colombia. The objective is to analyze the efficacy and safety of new treatment regimens, evaluating the parasitological response in comparison with standard treatment. In addition, an economic assessment will be carried out to analyze direct and indirect costs, including procedures associated with the management of adverse events.
Genitourinary Syndrome fo Menopause (GSM) is made up of a set of changes in the region of the vulva, vagina and lower urinary tract associated with a decrease in estrogen levels in the urogenital tissue, which leads to a reduction in blood supply, disorders in collagen metabolism and skin elasticity. The standard treatment for urinary incontinence during menopause is pelvic floor muscle training, associated or not with local hormone replacement therapy. Although low cost and easy to access, it is associated with low patient's adherence. Physical methods such as laser and radiofrequency in non-ablative, ablative and microablative forms are technologies that have recently been used in the vaginal mucosa to promote neoelastogenesis and neocollagenesis. It is hypothesized that menopausal women, who present symptoms of GSM, may benefit from this new, minimally invasive resource (microablative radiofrequency). This is a randomized clinical trial in which women aged between 40 and 65 years old will be included with clinical complaints of urinary symptoms associated with GSM. A basic anamnestic questionnaire will be used as the study instrument to collect sociodemographic, clinical data and symptoms, following the routine and standard of the service. To evaluate the treatment, the following will be used: voiding diary, pad test, vaginal cytology, histopathology, Female Sexual Function Index (FSFI), Short-Form Health Survey - SF-36 Questionnaire, King's Health Questionnaire, evolution of symptoms (dryness, pain during sexual activity, vaginal laxity, itching, burning sensation and pain in the vaginal introitus) and level of patient's satisfaction. Patients will be randomized into: group 1 or control group, which will perform pelvic floor muscle training, PFMT, with supervision (three times) and at home twice a day, and group 2 or test group, which will perform the same PFMT protocol associated with vaginal microablative radiofrequency. 10% lidocaine spray will be applied three minutes before the procedure and three applications will be made to the vagina/vaginal introitus, with an interval of 30 to 40 days. The purpose of this study is to test the efficacy and duration of effect of microablative radiofrequency in the treatment of urinary symptoms associated with GSM.
MIH is a condition with considerable prevalence in the child population. This structural defect, represented by a change in the color of the enamel, can be accompanied by structural loss and great sensitivity. Remineralizing agents have been used to strengthen compromised enamel. The objective of the study will be to measure the accuracy of a spectrophotometer (VITA Easyshade V) in determining the mineralization of IMH lesions by a CPP-ACPF dental mousse.
The objective of this randomized clinical trial is to compare the effects of a standardized exercise program alone versus the same program combined with neuromuscular electrical stimulation in patients undergoing heart failure . The main questions it aims to answer are: - Assessing the ultrasonographic parameters: echo intensity (echogenicity), cross-sectional area, thickness, and pennation angle of the rectus femoris muscle in both lower limbs. - Evaluating the strength of the femoral quadriceps muscle - Evaluating the changes in the chronaxie of the rectus femoris muscle in both lower limbs The protocol will have a total duration of 35 days, with an initial intervention period of 21 days (5 days per week), followed by a 14-day follow-up period.
Premarket, interventional, single-arm clinical study, to evaluate the safety and efficacy of Insight GS Growing System in the surgical treatment of Early Onset Scoliosis (EOS). Also, to evaluate the difference in height of the spine and trunk, the success rate of the procedure, monitor adverse events and evaluate the satisfaction of the patient and care providers. The Andromeda Insight Growing System (Insight GS) is intended to treat severe, progressive multi-planar spinal deformities such as early-onset scoliosis while allowing for skeletal growth. The Andromeda Insight Growing System consists of blades, clamps and pedicle screws used to form a distinct spinal construct in growing children. The implanted blade is used to brace the spine during growth and minimize the progression of scoliosis. The components are implanted from a posterior approach and are made from Titanium alloy (Ti6AL-4V-ELI), and High Density Polyethylene (HDPE). Patients from 3 to 10 years of age, or who are still skeletally immature, who present early-onset scoliosis and who are considered as able to receive the surgical procedure with the Insight GS system, will be included in the study. Patients will be screened in the outpatient setting of the study site. All participants who meet the eligibility criteria will be invited to participate in the study, which includes screening/pre-op, surgery to install the Insight GS system, and follow-up visits at 6 weeks, 2, 4, 6, 8, 10, 12,. 18 and 24 months for data collection, clinical evaluation, imaging, and monitoring of adverse events.
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 CKD and 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.
