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.
Objective: analyze the effects of isometric handgrip exercise on arterial pressure and on the autonomic cardiac modulation of hypertensive individuals treated in the Unified Health System (UHS). Intervention: Patients were randomized into Supervised group (SG) and control group (CG). SG will perform supervised isometric handgrip exercise for three weekly sessions in four sets with two minutes of isometric contraction with 30% of maximal voluntary contraction (MVC), In CG, individuals will be encouraged to increase their level of physical activity. Measurements: Blood pressure, autonomic modulation
This is a bioequivalence study of two doses of the dapagliflozin/metformin XR tablet manufactured at two different plants.
Obesity is one of the most concerning health issues in the modern world, especially due to its association with greater risk of developing a wide range of chronic diseases. Pre-gestational obesity may increase the chances of maternal and fetal morbimortality, such as gestational diabetes mellitus, preeclampsia, macrosomia and, even, fetal death. It may also lead to long term disorders, enhancing the risk of excessive adiposity and metabolic syndrome in later life and, thus, contributing to the maintenance of the obesity cycle and its health effects through the subsequent generations. Alterations in placental function are thought to be deeply involved in this scenario, however further research on its molecular and biological mechanisms is needed. During pregnancy, there is a physiological enhancement of the inflammatory state, marked by higher circulating cytokines and macrophage placental infiltration, which favors fetal nutrient supply and adequate growth; however, this response is exacerbated in women with pre-pregnancy obesity, leading to adverse outcomes. In this context, interventions aiming to reduce excessive inflammation may prevent or minimize the negative impact of pre-pregnancy obesity on both maternal and offspring's health. There is strong evidence suggesting an important role of n-3 LC-PUFA (EPA and DHA) on the attenuation and resolution of inflammatory states, besides influencing maternal lipid profile, fetal and infant adipogenesis and neurodevelopment. Additionally, the consumption of probiotic supplements during gestation seams to promote adequate maternal weight gain and improve the profile of inflammatory molecules secreted in the milk. Therefore, the nutritional interventions with fish oil, as a source of EPA and DHA, or probiotics, in women with pre-pregnancy obesity, may change the intrauterine environment and reduce the risk of both short and long term metabolic disorders. This study aims to investigate the metabolic and molecular changes promoted by gestational obesity and evaluate the effectiveness of different dietary interventions (fish oil or probiotic) on preventing or minimizing such alterations. We expect to contribute to the understanding of the physiological and molecular mechanisms underlying maternal obesity and its association with adverse pregnancy outcomes, associated with increased risk of chronic diseases in adulthood.
The purpose of this study is to determine whether Nivolumab, Ipilimumab combined with chemotherapy is more effective than chemotherapy by itself when treating stage IV NSCLC as the first treatment given for the disease
Non-carious cervical lesion is frequently associated with gingival recession, resulting in a combined lesion that has a different treatment prognosis when the two lesions appear alone. The literature presents few studies that propose a multidisciplinary approach (restorative and root coverage surgery procedures) to optimize the treatment of this combined lesion. The previously proposed approaches and materials have limitations and an optimal clinical protocol has not been established yet. Thus the aim of this study is to evaluate a novel multidisciplinary protocol with two resin composites and two different adhesive systems through a randomized clinical trial and laboratory studies. 120 combined lesions will be randomly assigned to one of the following groups: NP + TE (n = 30) - Partial restoration of cervical lesions with nanofilled composite and total-etch adhesive system and periodontal surgery for root coverage, NP + UA (n = 30) - partial restoration of cervical lesions with nanofilled composite and self-etching adhesive system and periodontal surgery for root coverage, MH + TE (n = 30) - partial restoration of cervical lesions with microhybrid composite and total-etch adhesive system and periodontal surgery for root coverage, MH + UA (n = 30) - partial restoration of cervical lesions with microhybrid composite and self-etching adhesive system and periodontal surgery for root coverage. Restorations will be assessed using the USPHS criteria after one week, six months and twelve months.
The purpose of this study is to verify the effects of continuous positive airway pressure (CPAP) on exercise capacity of children and adolescents with severe therapy-resistant asthma (STRA). A randomized, controlled, crossover clinical trial will be conducted. We expect the use of CPAP to increase exercise capacity in children and adolescents with STRA.
First, it will be evaluated whether supplementation of eriocitrin reduces hyperglycemia and insulin resistance, significantly reducing the risk of diabetes. The effects of eriocitrin on the lipid profile, inflammatory, endothelial, hepatic and renal biomarkers will also be evaluated. It is expected that metabolic parameters that constitute risk factors for diabetes and associated chronic diseases are expected to be improved by supplementation with eriocitrin
This study is designed to compare the knowledge, satisfaction and self-esteem of kidney transplanted adolescents measured through questionnaires between two groups: patients undergoing conventional treatment with no other intervention versus patients undergoing conventional treatment and receiving additional educational and consultative actions using a closed facebook group.
The main purpose of this study is to evaluate the efficacy of the study drug LY900014 compared to insulin lispro, both in combination with insulin glargine or insulin degludec, in adults with type 1 diabetes (T1D).
This study evaluates the effects of Pilates method and aerobic training in hypertensive subjects. Half of participants will be trained with Pilates, while the other half will be trained with aerobic exercise during 8 weeks.
