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.
Introduction: Patients with autoimmune rheumatic diseases (ARDs), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PAs), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), primary Sjögren's syndrome (pSS) , systemic sclerosis (SSc), idiopathic inflammatory myopathies (IIM) and primary vasculitides, have a high risk of herpes zoster (HZ) infection. This increased susceptibility is caused by a deficient cell-mediated immune response due to the underlying disease and glucocorticoid and immunosuppressive treatments that impair the T-cell response, including conventional and unconventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) and biological agents. In this context, the recent availability of a recombinant vaccine against HZ (RZV or Shingrix®), composed of recombinant VZV glycoprotein E (gE) and the AS01B adjuvant system (HZ/su), is a major progress regarding safety for immunosuppressed patients. Its effectiveness, however, has been clearly demonstrated for non-immunosuppressed patients and in selected populations of immunocompromised individuals. There are no prospective controlled studies evaluating the immunogenicity of RZV and its impact on the activity of the underlying disease, as well as its safety in patients with ARDs at high-risk for HZ. Hypothesis: RZV has a good safety profile, including with respect to underlying rheumatic disease activity, in patients with ARDs at high risk of HZ. Objectives: Primary: To assess the short-term safety profile in relation to underlying disease activity in patients with ARDs at high risk of HZ immunized with RZV compared to unvaccinated patients. Secondary: To evaluate the general safety of the vaccine in patients with ARDs at high risk of HZ immunized with RZV and non-immunosuppressed control subjects (CG); the humoral and cellular immunogenicity of RZV in patients with ARDs at high risk of HZ compared to CG; the influence of disease treatment on vaccine response; the 12-month persistence of humoral immunogenicity and incident cases of HZ. Specific studies will also be carried out to evaluate the effect of drug withdrawal (methotrexate-MTX and mycophenolate mofetil-MMF) after vaccination in increasing the immune response in patients with ARDs with controlled underlying disease.
A unicentric, blind, non-comparative clinical study to evaluate facial and body anti-aging efficacy of a supplement in female participants through clinical, subjective and instrumental evaluations.
This study investigates the efficacy and safety of belimumab compared to placebo, in addition to standard therapy, for the treatment of participants with systemic sclerosis associated interstitial lung disease (SSc-ILD). The study will evaluate the effect of belimumab treatment on lung function as well as on extra-pulmonary disease manifestations, including skin thickening and general symptoms, such as fatigue, that impact quality of life (QoL).
Chronic coronary syndrome (CCS) is the leading cause of death in women in the most developed regions of Brazil. The primary etiopathogenic mechanism is the process of atherosclerosis. A healthy diet rich in fruits and vegetables is associated with a lower incidence of CCS. The higher consumption of these foods promotes greater availability of phenolic compounds, and the higher intake of these compounds is one of the main hypotheses for vascular health. Quercetin, a phenolic compound, is the most abundant natural antioxidant belonging to the group of flavonoids. Quercetin improves lipoprotein metabolism, has an antioxidant capacity, produces vasodilating substances in the vascular endothelium, and reduces platelet aggregability. Likewise, statins are medications known to reduce cardiovascular events in women with CCS by reducing serum LDL-cholesterol levels and, to a lesser extent, by possible pleiotropic effects. In turn, SIRT1 is one of the 7 classes of proteins. It mediates various metabolic pathways in response to nutritional stimuli, particularly for caloric restriction and phenolic compounds, as well as coordinating the production and secretion of important hormones. However, the impact of quercetin supplementation and statin administration on serum endogenous estrogen levels is unknown
The investigational product constitutes a medical device that is freely accessible to consumers and, as such, must be safe under real or reasonably foreseeable conditions of use and its safety must be tested before being placed on the market. Therefore, this study was designed to evaluate the biocompatibility of the experimental product, as provided for in legislation.
The study was carried out within a large, urban prospective cohort of PLHIV at the Instituto Nacional de Infectologia Evandro Chagas (INI). Located in Rio de Janeiro, Brazil, INI is a national public referral center for PLWHA receiving primary care since 1998. From December 2019, adults who had attitudes toward quitting smoking and had no contraindications to study pharmacotherapy were enrolled by active site searching
The purpose of this observational study is to measure how many people are overweight or obese amongst patients with a diagnosed cardiovascular disease (CVD). The study also aims to characterise the population including the presence of cardiovascular (CV) risk factors in a number of countries across the globe representing different geographies, ethnicities, as well as different healthcare systems.
The sedentary lifestyle in women with breast cancer generates a problem for public health. An alternative that has been used to reduce sedentary behavior are interventions with the use of information technology, as well as projects with health education can cause lifestyle changes. However, little is known about the effect of these interventions on self-awareness and self-care in women with breast cancer. This aim of study is evaluate the effect of health education on sedentary behavior, lifestyle, physical activity level, nutrition, self-esteem, anxiety and depression, quality of life, pain, functional capacity, and strength in women with breast cancer. This is a study the 12 weeks, with patients being treated for breast cancer, distributed for two groups: Group Health Education Recommendations and Control Group.
Introduction: Greater Trochanter Pain Syndrome (GTPS) includes a number of disorders involving the lateral hip region, including bursitis, gluteal lacerations, and trigger points in the contractile tissue crossing the hip. As an alternative resource for pain relief, dry needling, known as Dry Needling (DN) is a technique that has been shown to be effective in the treatment of soft tissue injuries and neuromyofascial pain, with positive effects on musculoskeletal conditions. Objective: to compare the administration of ND and laser therapy on the effectiveness of reducing lateral hip pain and improving function in women with GTPS. Materials and methods: The sample will consist of 30 women, aged between 35 and 60, randomized into 2 groups: GND group (n=15) and GLT group (n=15). Participants will complete the sample characterization questionnaire, the numerical pain scale and the VISA Tendinopathy Questionnaire for Greater Trochanteric Pain Syndrome (VISA-G). Subsequently, they will be submitted to evaluation through functional tests sit and stand 30 seconds, Timed up and go test. After the evaluation, they will be submitted to the treatment. The GDN will receive treatment using the technique by a physiotherapist with specific training in NP. The application will be through the deep technique, in the regions of trigger points of muscles of the posterolateral region of the hip with duration of application from 30 to 60 seconds per point, 8 points of application will be standardized, in the region of muscles of the posterolateral region. hip side. The GLT will receive the Laser application by a physiotherapist specialized in traumato-orthopedics. The equipment will be the Infrared Laser (wavelength 904 nm), by punctual technique. Eight application points will be standardized in the muscles region of the posterolateral region of the hip.
This study will investigate the safety and efficacy of once daily oral treatment with orforglipron compared with placebo on body weight in adult participants with obesity or overweight and type 2 diabetes. The study will last about 77 weeks and may include up to 22 visits.
