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.
Introduction: Evidence indicates that muscle damage caused by exercise can lead to functional, biochemical and clinical damage. Therefore, it is pertinent to perform investigations related to the muscle damage marker, creatine kinase with clinical and functional responses. These outcomes encompass an intrinsic potential for understanding the real magnitude of interpretation of classic signals in athletic environments and monitoring of athletes, contributing to specific actions. Objective: To verify the correlation between clinical signs (pain and perception of recovery), functional (muscular strength) and the behavior of CK levels, in the moments following a simulated fight. METHODS: Six male parajiu-jitsu practitioners (34-44 years) were included in the study. The participants attended the collection site 4 times, with a 24-hour interval between sessions, characterizing the following collection moments: baseline, post-exertion, 24, 48 and 72 hours after the simulated fight. Data on pain (visual analogue scale - EVA), perception of recovery (Likert Scale), muscle strength (Dynamometry) and blood samples for CK analysis were collected. All parameters described were measured at all times of collection. For the analysis of the association between behavior of CK levels, clinical and functional variables, the Odds Ratio test and 95% confidence interval were used. For the gross values, the Pearson test was used according to the normality of the data.
Temporomandibular Dysfunction - TMD is considered the main cause of orofacial pain of non-dental origin, and a public health problem. Due to their complexity there are already treatments using various forms of therapy. Photobiomodulation using different light sources, in a single or combined form, makes it possible to use it as another therapeutic resource to be explored. The objective of this study will be to evaluate the effects of photobiomodulation with simultaneous use of light emitting diodes (LEDs), red and infrared, on clinical aspects in individuals with TMD. A randomized, controlled and blind clinical trial is proposed, which will involve 33 individuals (n = 11 per group) of both genders, aged 18-45 years in three groups: Group 1 - LED; Group 2 - placebo and Group 3 - control, submitted to 6 nonconsecutive sessions of photobiomodulation totaling 2 weeks of treatment. The Research Diagnostic Criteria for Temporomandibular Disorders - RDC/TMD will be used to determine the TMD and evaluate the participants. Pain will be assessed using the visual analog scale (VAS), mandibular range of motion will be determined with the aid of a digital caliper, and the electrical activity of the masticatory muscles will be verified by electromyography. A mixed plate of 18 red LEDs - 660 nm and 18 infrared LEDs - 850 nm with power of 3.5 mW per LED, 4.45 mW/cm2, radiant exposure of 5,35 J/cm2, irradiated area of 14.13 cm2, and energy of 75.6 J, in the temporomandibular joint (TMJ) region and in the masseter and temporal muscles, bilateral in 6 sessions. Participants from all groups will be reassessed after the first therapeutic intervention, and again at the end, following the same evaluation procedures used initially.
Illegal gold miners in French Guiana, a French overseas territory ('département') located in Amazonia, often carry malaria parasites (up to 46.8%). While the Guiana Shield Region aims at malaria elimination, the high prevalence of Plasmodiumin this hard-to-reach population in conjunction with frequent incorrect use of artemisinin-based anti-malarials could favor the emergence of resistant parasites. Due to geographical and regulatory issues in French Guiana, usual malaria control strategies cannot be implemented in this particular context.Therefore, new strategies targeting this specific population in the forest are required. Numerous discussions among health institutions and scientific partners from French Guiana, Brazil and Suriname have led to an innovative project based on the distribution of kits for self-diagnosis and self-treatment of Plasmodium infections. The kit-distribution will be implemented at "resting sites", which are areas across the border of French Guiana regularly frequented by gold miners. The main objective is to increase the appropriate use and complete malaria treatment after a positive malaria diagnosis with a rapid test, which will be evaluated with before-and-after cross-sectional studies. Monitoring indicators will be collected from health mediators at the time of kit distribution and during subsequent visits, and from illegal gold miners themselves, through a smartphone application. The project funding is multisource, including Ministries of Health of the three countries, WHO/PAHO, and the European Union.
Recent studies with photobiomodulation therapy have shown positive results in delaying skeletal muscle fatigue and improving performance through levels of biochemical markers and variables related to exercise when this therapy was applied before exercise. Some studies suggest that photobiomodulation therapy has systemic effects, but it is not known whether therapy exerts any systemic effects on human skeletal muscle. With this factor in mind, this research aims to verify the local and systemic effects of phototherapy on muscle performance and recovery after exercise in healthy male participants. This research consists in a randomized, triple-blinded, placebo-controlled trial, with participation of 30 healthy subjects. Will be analyzed parameters related to exercise performance (peak torque in the maximum voluntary contraction test- MVC), delayed onset muscle soreness (DOMS) by visual analogue scale (VAS), and biochemical marker of muscle damage (CK) and blood Lactate (BL). The analysis will be performed before exercise protocol (baseline), after 1 minute of the exercise, and 1, 24, 48 and 72 hours after the end of exercise protocol
Currently, with the increase of bacterial resistance to antibiotics associated with its side effects, it is necessary to find other adjuncts to combat the disease that are an alternative to the use of antibiotics. The use of probiotics has been proposed in the literature as an adjunct therapy for the treatment of periodontal diseases, however, few controlled and randomized clinical studies have been performed. The objective of this double-blind randomized controlled trial will be to evaluate the response of clinical and microbiological periodontal parameters to the comparison of two different adjuvant therapies (antibiotic and probiotic) for the treatment of stages II and III grade B periodontitis.
Background: The pulmonary rehabilitation effects on various outcomes of COPD are well known. However, they may be lost over time due to poor adherence to therapy with absence of regular exercise maintenance in long term, disease progression, comorbidities, falls incidence and higher exacerbations frequency. Currently, the main focus is to make the patient more active and ensure the benefits maintenance. However, few studies have been concerned with the aim of to investigate the long-term effect of this intervention and the relationship of the change promoted in important outcomes of the disease with its morbidity and mortality. Design: Non-controlled clinical trial, prospective and longitudinal. Setting: Outpatient pulmonary rehabilitation program in Florianopolis, Brazil Subjects: Patients with COPD (GOLD II-IV). Interventions: Pulmonary rehabilitation program (PRP) based on physical training, conducted over 24 sessions supervised, three times a week, including aerobic training in treadmill and resistance training for upper and lower limbs. Main measures: Before, post-PRP, 6 months post-PRP and 12 months post-PRP will be measured Spirometry or Total Body Plethysmography, Triaxial Accelerometry by Dynaport Activity Monitor, Glittre ADL-Test to evaluated functional capacity and functional performance, Six-Minute Walk Test distance on tracks of 20 and 30 meters, muscle oxygenation variables by NIRS PortaLite®, force platform NeuroCom® SMART Equitest®, Timed Up and Go Test, Berg Balance Scale, Activities-specific Balance Confidence, Falls Efficacy Scale - International - Brasil, London Chest Activity of Daily Living score, Modified Medical Research Council score, Saint George Respiratory Questionnaire score, COPD Assessment Test score and Hospital Anxiety and Depression Scale, Behavioural Regulation in Exercise Questionnaire-2, Basic Psychological Needs in Exercise Scale, General self-efficacy scale, COPD self-efficacy scale, Pulmonary Rehabilitation Adapted Index of Self-Efficacy. The death cases and numbers of exacerbations and hospitalizations will be measured by monthly phone calls after PRP.
This is a two arm, double blind RCT comparing the use of a single dose ciprofloxacin prior to SWL to saline alone. The multicenter trial will be conducted with a pragmatic emphasis including both high volume and low volume sites internationally.
The hypothesis of this study is that surgical techniques primarily designed for weight loss, ameliorates gastroesophageal reflux disease (GERD) in morbidly obese patients. Therefore the present study intends to evaluate such impact on patients submitted to two of the most common techniques available, the Roux-en-Y Gastric Bypass and Vertical Sleeve Gastrectomy.
