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.
Neuromuscular blockade is essential to provide optimal conditions for tracheal intubation and also to facilitate the performance of surgeries involving mainly the abdominal cavity. The introduction of neuromuscular blockers in clinical practice optimized the execution of mechanical ventilation. Since the use of these drugs, increased intercurrences such as prolonged muscle paralysis and respiratory complications have been observed, resulting in unfavorable outcomes with residual neuromuscular blockade and delayed recurrence due to the occurrence of these complications. The present study aims to evaluate the incidence of residual neuromuscular blockade and late recurarization in the post-anesthetic recovery room in patients submitted to videolaparoscopic cholecystectomy.
Genital herpes is a common and increasingly-common infection worldwide. The annual incidence in the United States is 1.75 per 1000 inhabitants. The etiologic agent is the herpes type 1 and 2 strains simplex virus. Classical Treatment is with acyclovir which decreases the duration of the disease and prevents rashes but has no curative effect. Also, studies show herpes resistance to acyclovir which has stimulating research into new drugs to treat this condition. Authors suggest melatonin way be a therapeutic agent in herpetic disease due to its modulatory action in immune and inflammatory responses when administered in adequate doses. Therefore, the aim of this study is to evaluate the effects of melatonin in the treatment of genital herpes as well as compare it to acyclovir in a double-blind, prospective and randomized, investigation. Outcome measures will include clinical evaluation of patients and laboratory endpoints.
This is a randomized, multi-center, double-blind, placebo-controlled, global, Phase III study to determine the efficacy and safety of durvalumab + Chemoradiotherapy versus Chemoradiotherapy alone as treatment in Women With Locally Advanced Cervical Cancer
The main objective of the research will be to analyze, through surface electromyography, the impact of inspiratory muscle training before a supervised home training protocol in patients with human T-cell lymphotropic virus type 1 (HTLV-1). For this, a clinical, longitudinal, prospective, quantitative and single center trial will be carried out, aiming at home inspiratory muscle training lasting 5 weeks, 3 times a week, 30 minutes daily through the IMT Threshold, with 14 volunteers enrolled in the Laboratory of Studies in Functional Rehabilitation (LAERF) of the Federal University of Pará (UFPA). They will be classified as the manifestation of Tropical Spastic Paraparesis / Myelopathy (PET / MAH) for GP (PET / MAH probable) and GD (PET / MAH definitive) groups, obeying inclusion criteria. For characterization of expiratory flow rates and flows, as well as respiratory muscle strength, they will be submitted to spirometry and manovacuometry, pre, per, and post treatment, respectively. For the analysis of the electromyographic activity, the diaphragm, parasternal and sternocleidomastoid muscles will be counted in the follow-up during the analysis of inspiratory muscle strength, as well as once a week during the conduction of the inspiratory muscle training protocol. The collected data will be stored in a Microsoft Office Excel® 2010 worksheet and then submitted to statistical analysis using the Bioestat 5.0® program, adopting a standard error of 5%. The theoretical support of the research will have a bibliographical survey of scientific articles collected during the design of the project, and the accomplishment of the research. It is expected to map, through the surface electromyographic study, the impact of respiratory muscle training at a distance on the inspiratory muscle strength of patients with HTLV-I virus with probable or definitive PET / MAH.
INTRODUCTION: Breast cancer is one of the pathologies affecting women worldwide, with a high mortality rate of 14,206 per 100,000 women per year. However, Pilates was used as a therapeutic treatment for women who underwent a modified radical mastectomy, being associated with the alterations when in the postoperative sequels. OBJECTIVE: to evaluate the Pilates Method in the functionality of women submitted to modified radical mastectomy. METHOD: This is a quantitative clinical trial, in the form of women included in the project, to undergo a physical therapy rehabilitation program through the Pilates Method for 2 months, where they were evaluated before and after the procedure for measurement and comparison obtained. CONCLUSION: In this way, the pilates method is presented as an instrument used for the rehabilitation of mastectomized women.
The objective of this research was to evaluate the clinical effect of photodynamic therapy on dentin infected by caries lesion in permanent teeth with Molar Incisor Hypomineralization (MIH). The study was composed of Groups (1 and 2). The methodology was based on the selection of patients from 6 to 12 years of age with permanent molar teeth, randomly divided. The selected teeth had deep dentin caries lesions on the occlusal surface, and sensitivity, indicated for clinical restorative treatment. Photodynamic therapy was applied with the use of low-intensity laser in permanent teeth selected for the treatment of infected dentin in G1. In this group, antimicrobial photodynamic therapy (aPDT) and atraumatic restorative treatment (ART) were made. In G2, only ART was performed. The teeth were restored with high viscosity glass ionomer cement. All patients had clinical and radiographic follow-up with a time interval of 6 and 12 months. Data were submitted to descriptive statistical analysis. For the evaluation of the association of categorical variables like age and gender, the Chi-square test and Fisher's exact test were used. To analyze the correlation between the continuous variables, the Pearson correlation test was applied. ANOVA and Kruskal-Wallis were applied for the analysis of dentin density in the radiographic images scanned and the microbiological results for colony forming units.

This study will evaluate the efficacy, safety, durability, and pharmacokinetics of faricimab administered at intervals as specified in the protocol, compared with aflibercept once every 8 weeks (Q8W), in participants with neovascular age-related macular degeneration (nAMD).
To investigate the efficacy of laser therapy associated with fluorotherapy in the desensibitization of hypomineralized teeth in children 8 to 12 years of age. A randomized blinded clinical trial will be conducted. The instruments used will be a questionnaire general, clinical examination, dental air syringe (evaluation of dental sensitivity) and visual analogue scale (evaluation of the magnitude of dental sensitivity). Teeth with hypomineralization molar-incisor (HMI) and the results of sensitivity and magnitude of dental pain before and after the treatments will be recorded in a clinical record. The study groups will be: treatment with laser therapy (Group 1); treatment with fluorotherapy (Group 2) and treatment with laser therapy and fluorotherapy (Group 3).
Introduction: The muscle contractile effectiveness is influenced by the neural activation of the motor units, as well as its architecture and the elasticity of the myotendinous junction. In addition, tendinous properties also affect the production of muscle strength and function. Neuromuscular electrical stimulation (NMES) is a wide-used tool in rehabilitation for motor relearning, to reduce muscular atrophy, pain control and to improve functional performance. Although studies have demonstrated the efficacy of NMES in various clinical situations, the best joint angle (ideal muscle length) to enhance neuromuscular and tendinous adaptations induced by NMES has to be determined. Objective: To investigate the effect of NMES on different hip and knee angles on knee extensor torque, quadriceps muscle electromyographic activity, architecture, and tendon-aponeurosis complex elongation, and tendinous properties of the patellar tendon. Material and Methods: This is a crossover study with healthy males, aged 18-35 years. The independent variables will be: 1) NMES in different lower limb positions: knee joint angulation at 20º or 60º with hip at 0º or 80º (four combinations). The dependent variables will be: knee extensor torque, surface muscle electrical activity, muscle architecture (muscle thickness, pennation angle and fascicular length), the elongation of the tendon-aponeurosis complex of the quadriceps muscle components, and the properties (stiffness, Young's modulus and cross-sectional area) of the patellar tendon. The descriptive and analytical statistics will be carried out with measures of central tendency and dispersion, inference tests, tables and graphs. The normality of the data will be verified with the Shapiro-Wilk test. For the data that present normal distribution, the Two-Way ANOVA will be applied to verify differences among the measurements, with post-hoc of Bonferroni. The non-parametric option will be the Friedman test. Correlation coefficients will be calculated using the Pearson (parametric) or Spearman (non-parametric) correlation test. The level of statistical significance will be p <0.05. Expected results: The effect of an NMES session on the neural, muscular and tendon adaptations related to the angular specificity of the hip and knee, indicating greater potential for strength and muscle mass gains, will be shown, which is fundamental in the prescription of electrostimulation in rehabilitation.
