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.
The goal of this randomized controlled trial is to investigate the effects of a dance intervention on cardiovascular risk factors and functional capacity of older women, comparing dancing to a walking exercise intervention and to an active control condition (stretching). The participants will include women between 60 and 80 years old, with body mass index inferior to 35 Kg /m2. The main outcome of this study is the peak oxygen consumption (VO2peak). The secondary outcomes are cardiovascular risk associated factors (C-reactive protein, TNF-alpha, lipid profile, etc) and functional performance (muscle strength and power, balance, gate ability, etc). The experimental design will include 3 parts: 1) Pre-intervention assessments: medical evaluation, fasting blood exams, maximum exercise test, assessments of body composition, balance, gate ability, muscular strength and power. 2) Period of interventions: patients will be randomized to one of the three following groups: dance, walking or stretching. The duration of the interventions will be 8 weeks, including 3 sessions per week for dance and walking, and once a week for the stretching group. Each session will last 60 min. 3) Post-intervention assessments: the same protocols of testing as pre-intervention.
There is evidence that computerized cognitive training can improve cognition in healthy older adults and in people at risk of developing dementia, although an effective model to implement the training in the daily life of people and to ensure engagement is missing. This project studies the adherence, engagement and progress on computerized cognitive training exercises that were offered by the Association of Retirees from the Telecommunications (ASASTEL) to its associates. One hundred subjects in three different cities (Rio de Janeiro, Belo Horizonte and Brasilia) received licenses to perform the exercises on line and were followed by a team of psychologists. We will evaluate adherence, engagement and progress on the computerized cognitive training exercises of those subjects.
Enteral nutritional therapy, fed through the gastrointestinal tract via a catheter, tube, catheter, or stoma, delivers the nutrients distally to the oral cavity and may reduce intrahospital malnutrition. Enteral probes are inserted, at the bedside, through the nose or mouth into the stomach or duodenum. Among the main complications of the use enteral probes, we can mention: displacement of the probe and administration of diet in the respiratory tract or microaspirations. To prevent displacement, enteral probes are attached to the skin on the nose or forehead by the use of micropore-type adhesive. In the probe the adhesive tape is put in the form of "tie" and again fixed to the nose of the patient. The enteral probes displacement rates with this technique are around 62%; in addition, the adhesive tape can cause discomfort, nasal necrosis, skin lesions and skin sensitivity reactions to the patient. More recently the nasal bridle, an anchor of the enteral feeding tube located around the nasal septum or nasal septum, has been described as more effective in securing enteral probes position over traditional tape attachment, but is not available in our environment. In Brazil, the feeding tube attachment device (FTAD) is available. Until now, the performance of FTAD in relation to enteral probe safety and accidental exit rates has not been described in the literature. Material's FTAD is composed of a layer of hydrocolloid that is adhered to the skin on the back of the nose and a polyurethane clamp that secures the enteral probe. Thus, there was a need to evaluate the actual success in using the traditional mode of probe attachment. It should be noted that very little scientific evidence is available in the literature on such care, and this is due to the lack of well-designed studies on the subject.
Periodontal diseases, such as chronic periodontitis (CP), frequently occur in immunosuppressed patients, including HIV-infected patients. The immunosuppression resulted by the HIV infection can justify the high frequency and the difficult in controlling the CP in this group of patients, raising the possibility of additional factors associated to the development of CP in HIV patients. The aim of this study is to determine factors that can be involved in the CP pathogenesis in HIV patients, including Candida spp presence, and biomarkers involved on the inflammatory response against the microorganisms.
The purpose of this study was to evaluate the efficacy and safety of pembrolizumab plus epacadostat compared to sunitinib or pazopanib in participants with locally advanced/metastatic renal cell carcinoma (mRCC) with a clear cell component who have not received prior systemic therapy for their mRCC.
Dementias are neurodegenerative syndromes typical of the elderly population and causing a high degree of disability and sick of dependence on others for care. Caregivers of patients with dementia, especially those belonging to the same family suffer with high overhead and is often affected by losses in their own health. The aim of this study is to evaluate the efficacy of a psychoeducation and protocol support, conducted by telephone, in aid of patients with dementia caregivers in specialized outpatient treatment. It will be selected patients in outpatient specialized care. The primary outcome is the change in Zarit Scale.
Most trauma deaths are related to traumatic brain injury (TBI). Although the management of patients has improved, mortality remains unacceptably high, and half of survivors of moderate and severe TBI are left with major functional impairment. Current management guidelines are based on limited evidence and practice is highly variable. Most acutely ill patients with TBI will develop anemia, which may decrease oxygen delivery to a fragile brain. While clinical practice is moving towards transfusing at low hemoglobin (Hb) levels, experts have expressed concerns regarding restrictive strategies, which may adversely affect clinical outcomes in TBI. Our primary objective is to evaluate the effect of red blood cell (RBC) transfusion thresholds on neurological functional outcome. We hypothesize that a liberal transfusion strategy improves outcomes compared to a restrictive strategy.
The purpose of this study is to evaluate the efficacy of SHP647 in inducing remission, based on composite score of participant-reported symptoms and centrally read endoscopy, in participants with moderate to severe ulcerative colitis (UC).
In several diseases in which muscle weakness is a determining factor for morbidity and mortality, inspiratory muscle training has been shown to be useful in improving the function of ventilatory muscles, delaying or minimizing the development of complications due to the reduction of inspiratory muscle strength. The breath-stacking technique emerges as an easily applicable alternative, and it can be used in poorly collaborative patients. The technique described in the literature aims to increase pulmonary volumes. This gain occurs with the coupling of a silicone mask on the patient's face, a unidirectional valve and with the expiratory branch occluded. Thus, inspirations occur sequentially in this medium, generating pulmonary hyperinflation and increasing the contractility power of the expiratory muscles, which are fundamental for coughing. This hyperinflation also improves the peripheral air distribution in the lungs by increasing intrathoracic pressure. The objective of this study is to evaluate the effect of the breath-stacking (BS) technique on the ventilatory muscle strength of young and healthy individuals.
Hypertension is considered a serious public health problem. The imbalance in autonomic nervous system (ANS) activity is one of the main triggers in the development and maintenance of hypertension. The non-pharmacological management of this disease is an important resource, especially in refractory hypertensive patients or in hypertensive crises, where the pharmacological treatment does not present an efficient response. It is known that transcutaneous electrical nerve stimulation (TENS) is capable of modifying the autonomic balance, however, the effects of Interferential electrical stimulation (IES) on this system in normotensive and hypertensive volunteers are not yet known. These electrotherapeutic resources may be a non-pharmacological tool supporting the management of hypertension. The objective of this research is to study the effects of different TENS and IC parameters on cardiovascular variables of normotensive volunteers and hypertensive patients.
