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 clinical study is aimed at investigating the effects of transcranial direct current stimulation (tDCS) on COVID-19 patients not admitted to the intensive care unit. The tDCS is a non-invasive brain stimulation technique which applies a low intensity electrical current in order to modulate neuronal activity. Patients included will be submitted to a single session with active or sham tDCS, aiming to modulate prefrontal or supplementary motor area (SMA). Evaluation protocol will be performed before and after stimulation to verify the incidence of adverse events related to treatment and whether tDCS would affect measures of executive functioning, mood, anxiety, autonomic response and motor function in COVID-19 patients. We hypothesize the neuromodulation would be a safety, promising treatment to reduce possible impairments in COVID-19 patients.
This is a randomized study that sought to analyze the diagnostic accuracy of the telemedicine consultation of patients suspected of respiratory tract infections during COVID-19 pandemic in comparison with the face-to-face evaluation at the emergency department.
The long and very long stents, although they represent a greater navigability challenge, especially in tortuous and calcified coronary arteries, they have the advantage of providing shorter procedural time, with less contrast use, less exposure to radiation, lower cost, lower risk of occlusion of lateral branches, as well as less interference in the local flow. However, in the context of the use of such long stents, as some vessels have a tapering shape, with a progressively smaller diameter in their more distal segments (as is the typical case of the left anterior descending artery), a significant disproportion (mismatch) of vessel size between the proximal and distal landing zone of the stent can be noted. Such disproportion may lead to the underestimation of the proximal reference or overestimation of the distal reference diameter of the vessel, generating an increase of the stress on the vessel wall, with consequent increase in the risk of restenosis. In view of this situation, long or very long stents were developed in a tapered shape, with progressive reduction of their diameter between their proximal and distal portion, respecting the phenomenon of tapering of the coronary artery during the treatment of very long lesions.Some of these stents also have a hybrid design, with closed cells at the ends and open cells in the middle, allowing a more efficient expansion in their middle portion (thus avoiding the dog-boning phenomenon). However, there is still a lack of studies in the literature evaluating whether these DES in a tapered shape and hybrid cells may effectively heal over time, specially with respect to strut covering and strut malapposition. Thus, this is a prospective, single-arm, open-label study, including patients presenting at least one long or very long lesion (≥ 30 mm), who will undergo angioplasty with a tapered DES. The objective is to analyze the neointimal healing as well as other data on the efficacy and safety of the tapered DES Biomime Morph in patients with long or very long lesions.
Comorbidities associated with severe obesity determine an important public health problem. Few methods are considered potentially effective for the treatment of severe obesity and the clinical relevance of bariatric surgery is growing, as well as the number of procedures performed. The insertion of the physiotherapist in the multiprofessional team responsible for performing the surgical procedure is essential from the preoperative screening and evaluation to the prevention and treatment of postoperative complications. Therefore, the physiopathological aspects involved with severe obesity, the technical aspects and risks of the surgical procedure, as well as the physiotherapeutic techniques that have scientific proof must be known by the physiotherapist responsible for the surgical follow-up of the patient. In this context, the use of non-invasive ventilation (NIV) in the postoperative period of bariatric surgery has ample therapeutic potential. The present research project aims to evaluate the immediate prophylactic use of NIV on the respiratory and functional recovery of the patients.
The presence of multimorbidities is very common among the elderly, which become major consumers of medicines. The process of prescribing medicines for the elderly should be done with caution, as the use of some medications may present more risks than benefits in this range age. Potentially inappropriate prescribing for the elderly has become a global concern for the promotion of an adequate pharmacotherapy, it becomes essential to be aware of the effectiveness and safety of medicines and the knowledge of which drugs whose risks of serious adverse reactions outweigh the benefit of your referral. In this sense, the present study has aim to evaluate the effectiveness of pharmaceutical interventions in frequency of omission of drugs with proven efficacy for cardiovascular diseases and promotion of treatment prescription inappropriate and polypharmacy. A prospective quasi experimental before and after study will be carried out in elderly patients diagnosed with cardiovascular disease admitted to the Ana Nery hospital, Salvador, Bahia, Brazil. A convenience sample will be collected, the data will be released and revised in a database built in the SPSS software and analyzed in the program statistic R and SPSS. At the end of the study, it is expected a decrease in the frequency of omission of medications and promotion of prescription drugs inappropriate.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes challenging immune and inflammatory phenomena. Though various therapeutic possibilities have been tested against coronavirus disease 2019 (COVID-19), the most adequate treatment has not yet been established. Among candidate adjunct treatment options, propolis, produced by honey bees from bioactive plant exudates, has shown potential against viral targets and has demonstrated immunoregulatory properties.
Is treatment with the Leap Motion Controller device effective for upper limb functionality in individuals with Parkinson's Disease? The present study presents two hypotheses: True hypothesis: There is an improvement in the functionality of MMSS after intervention with virtual reality? Null hypothesis: There is no improvement in the functionality of MMSS after intervention with virtual reality? The proposed work will be characterized as a Randomized Clinical Trial, with evaluators outside the experimental groups (single-blind). The sample will be probabilistic, from individuals diagnosed with Parkinson's disease.
This study compares insulin icodec (a new insulin taken once a week) to insulin degludec (an insulin taken once daily which is already available on the market) in people with type 2 diabetes. The study will look at how well insulin icodec taken weekly controls blood sugar compared to insulin degludec taken daily. Participants will get their study medicine in an injection pen. Participants will get a pen for weekly injection and one for daily injection. One will be icodec or degludec and the other will be dummy medicine. The treatment participants get is decided by chance. Participants and the study staff will not know which active medicine they get. The insulin is injected with a needle in a skin fold in the thigh. The study could last for about 8 months. Participants will have 13 clinic visits and 17 phone calls with the study doctor. At 8 clinic visits participants will have blood samples taken. At 4 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

Design: Randomized controlled double-blind study. Setting: Specialist Rehabilitation Services.
Viral diseases have always posed a threat to public health. Recently, the SARS-Cov2 virus spread in an epidemic that began in China and soon spread globally, making its study extremely relevant, in order to seek mechanisms to combat it. Therefore, this study seeks to evaluate the benefit of using Hydroxychloroquine with or without Apixaban in the early treatment of patients with suspected COVID-19. Prospective, randomized, double-blind, controlled study, performed at Hospital das Clínicas Samuel Libânio (Universidade do Vale do Sapucaí) UNIVÁS, Pouso Alegre, Minas Gerais, Brasil. Patients treated in the emergency department who are reported as suspected cases of COVID-19 patients will be included, according to current guidelines. Will be randomized into 4 groups: Hydroxychloroquine, Hydroxychloroquine + Apixabana, only Apixabana and Control group, all receiving standard treatment recommended. Included patients will be monitored during hospitalization or remotely assisted in home treatment. Clinical, laboratory, electrocardiographic and image evaluation criteria will be considered to assess the evolution in 7 and 14 days after inclusion. Results will be subjected to appropriate statistical analysis, with sample calculation. An early therapeutic approach is proposed in suspected and confirmed patients with COVID-19, with the hope of reducing hospitalizations and severe forms of the disease.
