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.
A randomized open-label trial will be conducted to evaluate the effect of vocalization as a perineal protection maneuver during the second period of labor. The study will be carried out in the "Espaço Aconchego" sector of the IMIP, which has a team of obstetrical nurses, medical coordination and physiotherapeutic support. The study population will consist of low-risk parturients, with no prior cesarean indication, admitted to the sector. Those parturients who meet the inclusion criteria, after signing the Informed Consent Term, will be allocated to two groups: Group A (experimental) and Group B (control). Group A will be stimulated to keep the glottis minimally open during spontaneous pushing and to emit sounds when exhaling (vocalization), and Group B will undergo usual routine. Study outcomes will be evaluated by assistents immediately after delivery. After 24 hours of delivery, the conditions of the perineum will be assessed by inspection and palpation of the region,evaluating the presence of edema or other abnormality.
The objectives of this study are to characterize MPS VII disease presentation and progression and assess long-term effectiveness and safety, including hypersensitivity reactions and immunogenicity of vestronidase alfa.
Attempting an effective treatment is essential to the physiotherapist to understand how his conducts affect body tissues and the whole system, besides understand properly how and when therapeutic modalities could be use in the rehabilitation process. There are several research articles pointing the use of heat as an efficient agent to accelerate tissue healing. Clarifying the remaining doubts related to therapeutic modalities use can be beneficial for functional rehabilitation. In physiotherapy, shortwave diathermy is one of the standards treatments for heat inducement. The capacitance shortwave technique consists in the use of two pad electrodes that can be positioned in three different arrangements: coplanar (placed side by side on the same aspect of the part to be treated), contraplanar (placed over opposite aspects of the body part to be treated) and longitudinal (one electrode is placed at each end of the limb in opposite aspects of the body par to be treated). There is no evidence of which arrangement is the most efficient. Besides shortwave diathermy being a very established therapeutic modality, the use of this recourse in the most effective way rely on the properly answer of the remaining questions related to its application. Therefore, the purpose of this study is to analyze which one of the capacitance shortwave technique is the most efficient in inducing and maintaining heat. Given the high-frequency waves field orientation could be suggested that the coplanar arrangement will lead to bigger heat inducement, and will maintain it for longer time.
The objective of this study was to evaluate the efficacy of three methods for removal of dental biofilm when compared to dental toothbrushing control. Twenty patients were diagnosed and randomized into four groups according to the method tested: 1) apple 2) Rolly Brush 3) chewing gum and 4) brushing control. Subjects were evaluated four times according to the method used. All were evaluated before performing any method and after using each of the four methods separately. The patient's evaluation interval was 24 hours between the use of the methods. In the first stage, they underwent a clinical examination in which the needs of supragingival scraping or definitive restorations and prophylaxis were detected. After this step, all methods of oral hygiene and the consumption of fibrous foods and chewing gum were suspended for twenty-four hours. In the second stage, with a minimum of twenty-four hours after the first, volunteers received approximately 10 ml of basic fucsin to perform a mouthwash. The dental examination was then carried out for measurement on each dental surface and the plaque index was recorded on each surface. In the latter, four evaluations were performed with at least a 24-hour interval until the patients used the four methods
Osteoarthritis (OA) is one of the most frequent causes of chronic pain, often intense, debilitating and responsible for a large percentage of the elderly. The disease affects about 10% of adults and the knees are the most affected joints. The diagnosis of OA in the knee is predominantly clinical, and can be confirmed by radiological examination. Systemic drugs are indicated before invasive procedures, but pharmacological therapies may offer limited benefits. Thermal radiofrequency lesions of genicular nerves has been used to relieve chronic knee pain, as adjuvant therapy, but with high costs and low availability in the public system. The use of phenol for peripheral analgesic blocks has emerged as a good option and at low cost and can be used in any service of Pain Treatment. The aim of the study is to evaluate the efficacy of 6% phenol for ultrasound-guided genicular nerves neurolysis for the treatment of patients with chronic knee pain due to osteoarthritis. METHODS: A prospective study will be carried out with 15 patients with chronic pain (more than 4 months) and diagnosis of arthrosis by imaging, with pain intensity greater than 4 (from zero to 10) that will be submitted to ultrasound-guided genicular nerves block. The test block will be performed with 0.25% -1,5 mL bupivacaine on each nerve. Patients who present pain improvement> 50% will undergo neurolysis of genicular nerves with 1,5 mL of 7% phenol in each of the genicular nerves. After the procedure, the patients will be evaluated for 3 months in relation to the intensity of pain at rest and movement and duration of analgesia provided by the intervention, range of movements and functionality of the knee joint.
Introduction: studies on resistance training of low intensity associated with blood flow restriction in recent years, although there are still gaps that can be explored in relation to their physiological phenomena when associated with eccentric training. In this way, from there the exploration becomes relevant the investigation of eccentric training associated to an RFS. Objective: To analyze and compare the effects of a high intensity and low intensity intensive resistance training associated with an RFS (TREAI-RFS and TREBI-RFS) with a high intensity eccentric resistance training without RFS (TREAI) in knee extensors. Method: The study will consist of 45 male participants, allocated from a stratified randomization into three groups: TREAI (n = 15), TREAI-RFS (n = 15) and TREBI-RFS (n = 15). Participants underwent a training program with a minimum of 40% without RFS, 80% with RFS and 40% with CVS of CVIM, 3 times a week, and the outcomes of muscle strength, muscle structure, power test and Endothelial growth will be assessed one week before, the fourth week and one week after the end of the training program. In addition, clinical markers of perception and recovery effort are investigated before and after a session. The graph used is descriptive and descriptive, as it is used as a model of analysis of variance for the analysis of replications without a two-factor scheme, which provides detailed information on how the measures are repeated, neither. A whole statistical analysis can reach the level of significance of 5%.

Stroke is a frequent complication of sickle cell disease (SCD), with varying levels of central nervous system (CNS) involvement. The summation of several ischemic events, even when silent, can lead to devastating consequences, from reduced academic performance to physical dependence. Despite knowledge that brain flow velocities evaluated by Doppler ultrasound identify pediatric SCD patients at a greater stroke risk (Adams et al, NEJM 1998; 339:5-11), this method is not able to predict the occurrence of strokes in adults. There is also no consensus on the management of adult patients in relation to primary and secondary prevention. The aim of this study is to evaluate the effects of the administration of Simvastatin on CNS structural and functional vascular changes in 30 adult patients with SCD (SS and Sβ), above 35 years of age, observed through Magnetic Resonance Imaging (MRI). The data on the effect of simvastatin on disease manifestations is quite scarce, however this drug reportedly significantly reduces plasma concentrations of adhesion molecules and inflammatory markers, such as E-selectin, VEGF, CRP and IL-6 (Hoppe et al, BJH 2011; 153:655-663; Hoppe et al, BJH 2017;177:620-629). Thus, in addition to the search for early diagnostic markers and risk stratification for primary or recurrent stroke, we will also compare CNS images before and 12 months after the administration of Simvastatin. The drug alter stroke recurrence rates in the general adult population, but their effects on vascular changes in patients with SCD have not yet been adequately elucidated. This is particularly important because these are low cost drugs which present good tolerability, and could be part of the therapeutic arsenal of SCD, even in low income settings. Concomitantly with the CNS evaluation, this study also intends to investigate molecular pathways that may be affected by the drugs. We will evaluate microvesicle release patterns, as well as the content of microRNAs possibly involved in the occurrence of stroke, in addition to metabolomic studies and plasma cytokine profile.
