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.
To evaluate Brazilian gynecologists, through structured online questionnaires, with questions directed to their opinions and prescriptive habits about menopause hormone therapy. Research participants will complete the questionnaires in digital format online.
The purpose of this study is to evaluate the safety and tolerability of extended dosing with Eplontersen in participants with hereditary transthyretin-mediated amyloid polyneuropathy (hATTR-PN).
Diabetic foot ulcers (DFU) are aggressive complications of diabetes mellitus (DM) and affect 25% of these patients. DFU are associated with a high risk of amputations and early mortality and significantly impact quality of life (QoL). The low-level laser therapy (LLLT) is an important approach for the treatment of DFU, however there is a lack of data on its influence on the QoL of patients with DFU. On the other hand, adherence to self-care is a factor closely related to QoL. Therefore, this study is justified by the need to understand the impact of LLLT on QoL and its relationship with self-care. Aim: To evaluate the quality of life of patients with diabetic foot ulcers treated with different doses of LLLT (GaAs) 904 nm and its association with aspects of adherence to self-care. Methods: This is a randomized, double-blind, placebo-controlled clinical trial. Participants will be randomly assigned to the groups: control LLLT placebo (CG), LLLT 904 nm 10 J/cm² (LG1), LLLT 904 nm 8 J/cm² (LG2) and LLLT 904 nm 4 J/cm² (LG3). QoL data, percentage of healing and pain will be assessed before the start of the intervention, in 10th week and after one month to the end of intervention, self-care will be assessed before the start of the intervention and at the end of intervention. Eighty participants with DFU will be recruited who will receive intervention twice a week for up to 20 visits (10 weeks).
The primary objective is: To evaluate the effect of pozelimab + cemdisiran on daily functioning that is impacted by signs and symptoms in patients with symptomatic generalized myasthenia gravis (gMG) The secondary objectives of the study are: - To evaluate the effect of pozelimab + cemdisiran (ie, combination) and cemdisiran monotherapy on: - Clinician-assessed signs of myasthenia gravis (MG) and muscle strength - Daily functioning that is impacted by signs and symptoms in patients with symptomatic gMG (cemdisiran monotherapy only). - Proportion of patients with improvements in daily function that is impacted by signs and symptoms of MG - Proportion of patients that have improvements in clinician-assessed signs of MG and muscle strength - Health related quality of life - Proportion of patients with minimal MG symptoms - Patient- and clinician-reported signs and symptoms of MG - To evaluate the safety and tolerability of pozelimab + cemdisiran and cemdisiran monotherapy - To assess the concentration of total pozelimab in serum - To assess the concentrations of cemdisiran and its metabolites in plasma - To assess the immunogenicity of pozelimab - To assess the concentration of total C5 in plasma - To assess the immunogenicity of cemdisiran - To study the effect of pozelimab + cemdisiran and cemdisiran monotherapy on complement activation
The purpose of this study is to assess the ActTeens (Active teens) Program to improve the physical activity level, physical fitness, cardiometabolic and mental health in adolescents. The investigators hypothesize that that intervention group participant's fitness and physical activity levels will improve during this period in comparison with control group participants.
Ultrasound-guided blockage of the erector plane of the spine (known as ESP BLOCK) is a recently described block and a very useful strategy in the perioperative period as it provides effective analgesia in thoracic surgery. Ultrasound-guided type II pectoral nerve block (internationally known by the acronym Pecs II block) is a very useful strategy in the perioperative period because it provides effective analgesia in breast surgeries and can optimize results. The aim of this study is to assess perioperative pain in mastectomies. This is a prospective, randomized, single-blinded study that will compare the effects of spinal erector plane block versus pectoral nerve block in patients scheduled for mastectomy. The ESP group will receive balanced general anesthesia associated with ESP BLOCK with 0.5% ropivacaine guided by ultrasound. The Pecs II group will receive balanced general anesthesia associated with Pecs II block with 0.5% ropivacaine guided by USG.
The aim of this study is to determine the acute effects of diazepam on beat-to-beat blood pressure variability and baroreflex control.
LIVER PAM A randomized, controled, open and unicentric trial comparing high (MAP 85-90 mmHg) and low (65-70 mmHg) target of mean arterial pressure in the first 24 hours after liver transplantation.
This is a Phase 3 study to assess the efficacy and safety of twice-weekly subcutaneous (SC) doses of pegcetacoplan compared to placebo in patients with C3 glomerulopathy (C3G) or immune-complex membranoproliferative glomerulonephritis (IC-MPGN) on the basis of a reduction in proteinuria.
Fibromyalgia is a public health condition, which causes great functional disability. Conventional treatment modalities have been shown a very poor therapeutic response, in that most individuals end up becoming poly-medicated and refractory to treatment. Non-pharmacological techniques with promising effects on the syndrome symptoms include both hypnotic analgesia and the transcranial direct-current stimulation (tDCS). Giving the treatment limitations of this syndrome its important to better understand the pain processess in fibromyalgia and treatments effect. This project was developed in order to evaluate the synergistic effect of a hypnotic analgesia suggestion associated with tDCS over pain levels and cortical excitability in individuals with fibromyalgia over a nociceptive stimulation pattern.
