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.
This was a phase IV Open-label, single-arm, single-dose, multicenter study, to evaluate the safety, tolerability and efficacy of intravenous administration of OAV101 (AVXS-101) in patients with SMA with bi-allelic mutations in the survival motor neuron 1 (SMN1) gene ≤ 24 months and weighing ≤ 17 kg, over a 18-month period post infusion.

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 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.
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 study will evaluate the safety and efficacy of a moisturizer body lotion: the study aims to determine the tolerance of this product by the study population, and its effects on atopic dermatitis condition, skin hydration, skin barrier, skin microbiome and perceived efficacy. Participants will receive the product to use it at home for 21 +/- 2 days.
The use of synthetic mesh to repair infected defects of the abdominal wall remains controversial. This study aimed to evaluate the short-term outcomes of using PVDF mesh to treat infected abdominal wall defects in the elective setting.
Neuromuscular Electrical Stimulation (NMES) can minimize muscle atrophy, complications related to muscle disuse and improved neuromuscular performance. However, it is still unclear the influence of specific physical parameters, including carrier frequency, burst duration, and duty cycle regarding the greater generation of evoked torque, sensory discomfort, muscle fatigue, and peripheral oxygen extraction. Thus, the aim of this study is to compare the effects of different NMES protocols applied to the triceps surae muscle for evoked torque, muscle fatigue, sensory discomfort, and peripheral oxygen extraction in healthy individuals. This is a crossover, experimental, randomized, double-blind trial composed of apparently healthy participants. All NMES protocols will be tested on the same individual with randomization of the sequence of intervention protocols. There will be a total of 6 encounters with seven days between them. Session 1 will evaluate the anthropometric measures, the maximum intensity for each intervention protocol, and the sequence of intervention protocols for each individual will be randomized. Sessions 2, 3, 4, and 5 will be composed equally with the assessment of the maximum voluntary and evoked joint torque of the triceps surae muscle through the isokinetic dynamometer, evaluation of muscle fatigue through the H-reflex, M-wave, fatigue index, time-torque-integral, and recruitment curve, evaluation of peripheral oxygen extraction through NIRS (Near Infrared Spectroscopy), electromyographic signals to assessed the RMS (root mean square) and the median frequency, evaluation of the level of sensory discomfort through the Visual Analog Pain Scale and finally by the NMES protocol. The 6th session will be the replication of the 2nd session of each individual. The EENM protocols will be as follows: CR10% (Russian Current with 2500 Hz, modulated in bursts of 50 Hz, 200 µs and 10% duty cycle - 2 ms bursts and 18 ms interbusrts), CR20% (Russian Current with 2500 Hz, modulated in bursts of 50 Hz, 200 µs and 20% of duty cycle - 4 ms bursts and 16 ms interbusrts), CA10% (Aussie current with 1000 Hz, modulated in bursts of 50 Hz, 500 µs and 10% duty cycle - 2 ms of bursts and 18 ms interbusrts), CA20% (Aussie current with 1000 Hz, modulated in bursts of 50 Hz, 500 µs and 20% of duty cycle - 4 ms of bursts and 16 ms interbusrts) all protocols will be performed on the triceps surae muscle.
Currently, the tools available for assessing peripheral muscle dysfunction in the intensive care setting require patient collaboration. Several studies have shown that peripheral muscle ultrasound is capable of reliably detecting morphological changes in critically ill patients, in addition to contributing to the identification of patients at higher risk of prolonged complications, especially when performed daily. In this sense, a valid, non-volitional alternative capable of determining muscle mass is through ultrasound assessment. However, current studies are characterized by a lack of standardization in their protocols, which include proper positioning of limbs, transducer, clear reference points and techniques for better visualization of the assessed muscle, in addition to significant methodological defects and inadequate sample sizes. We believe that, together with a tool capable of determining muscle mass and being a safe and non-invasive method, we can contribute to a more complete assessment of these patients, exploring outcomes such as survival, length of stay in the ICU, extubation success and functional capacity. In addition to having the potential to serve as a biomarker of muscle strength during rehabilitation, given little knowledge about the long-term physical consequences of COVID-19, thus promoting a more complete assessment, exploring morphological characteristics of the peripheral muscles resulting from the hospitalization process. and assisting the physiotherapist in clinical decision making in rehabilitation.
