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.
Low back pain (LBP) is a highly prevalent condition worldwide and the leading cause of years lived with disability. In most cases, the specific pathological cause remains unidentified; therefore, the term non-specific low back pain is commonly used for such cases. Many non-pharmacological therapies are available for the treatment of low back pain aiming to reduce pain and disability. Among these options, photobiomodulation therapy (PBMT) it seems to be an interesting alternative. PBMT is a non-thermal and non-invasive clinical treatment, which has shown effects in decreased pain, modulation of inflammatory process, and tissue repair in musculoskeletal disorders. Therefore, the aim of this project is to evaluate the effects of the PBMT against placebo on pain intensity in patients with chronic non-specific low back pain.
INTRODUCTION: Seroma is the most common complication after surgical treatment for breast cancer. It is the abnormal accumulation of serous fluid that develops under skin flaps and may be associated with necrosis, dehiscence, sepsis, and shoulder dysfunction. The therapeutic bandage has been inserted in clinical practice because it is similar to the elasticity of the skin and is able to help the circulatory and lymphatic system, reduce pain and local swelling, and may have benefits for prevention and treatment of seroma when applied compressively. . OBJECTIVE: To evaluate the effectiveness of compressive bandage in preventing seroma. METHODOLOGY: Randomized study of women over 18 years who underwent mastectomy at HCIII / INCA. Eligible patients will be allocated to the intervention and control groups by lot (270 envelopes, 135 patients per group). The intervention group, in addition to the use of the drain, will be submitted to the compression bandage on the day of hospital discharge and will be reevaluated on the seventh day. The control group will follow the institutional routine, using only the drain. The incidence and volume of the seroma, as well as the length of stay of the drain will be evaluated after 30 days through the medical record. Symptoms and skin changes resulting from the use of the bandage will be evaluated through a specific form. ANALYSIS: Descriptive analysis will be by measures of central tendency, dispersion and frequency distribution. Outcome assessment will be performed by odds ratio (for categorical variables) and by mean difference (Student's t-test), considering a 95% confidence interval. To control the confounding variables, multiple logistic regression (categorical outcome) and multiple linear regression (continuous outcome) will be performed by the Stepwise Forward method, including variables with p <0.20.
Several clinical trials have demonstrated the positive impact of physical functioning and fatigue in patients who received training programs during the myeloablative chemotherapy with stem cell transplantation. However, the heterogeneity among the forms of physical activity results in moderate to very low evidence available about benefits of physical exercise. In this randomized and controlled clinical trial, we will study the effects on physical performance and fatigue of periodic resistance training programs, with an autoregulated approach within a non-linear model, based on the individual patient response to cancer treatment.
Obesity today has become one of the main public health concerns. As a consequence, different strategies have arisen to fight weight gain. One of the alternative strategies to increase the success of therapeutic approaches to weight loss is the increase in energy expenditure, through thermogenesis, regulated by the beige/brown adipose tissue (BAT). Studies have shown that beige/BAT has a strong correlation with body weight regulation. It has also been demonstrated that cold exposure activates beige/BAT. Recent studies, mainly in animal models, suggest that beige/BAT can also be activated by specific food and nutrients. Concomitantly, new dietary interventions, to treat obesity, have also been studied. One of these dietary interventions is the Fasting Mimicking Diet (FMD). Since FMD is high in unsaturated fat, and clinical trials have shown that FMD interventions reduced body weight and improved metabolic health, there is a possible association between this diet and the activation of beige/BAT. The aim of this is study is to investigate the effect of Fasting Mimicking Diet on the activation of beige/brown adipose tissue, in humans with overweight. This will be an open clinical trial with the duration of three consecutive months (three cycles of the FMD diet). There will be an FMD and a control group. The following data will be collected before and after the intervention, for each group: dietary intake and physical activity data, evaluation of beige/brown adipose tissue activation (Positron Emission Tomography - PET with fluoride-18-labeled fluorodeoxyglucose (18F-FDG) in combination with computed tomography - PET/CT scan, Thermal Imaging, BAT adipokines and genes related to BAT activity), basal metabolic rates and caloric needs (Indirect Calorimetry), anthropometric measures and body composition (DEXA scan), lipid profile and inflammatory markers. Data will be expressed as mean and standard deviation and the variables will be compared by Student's t-test or ANOVA, for repeated measures.
The advent of laparotomy replacement by minimally invasive techniques brought the obvious benefit of postoperative pain reduction. The application of transversus abdominis block has already demonstrated to reduce postoperative pain in laparoscopic hysterectomy. The comparison between it and quadratus lumborum block in cesarean sections showed that the latter was superior in relation to postoperative analgesia. The aim of this trial is to compare postoperative analgesia in patients receiving one or the other of these regional anesthesia techniques to prevent postoperative pain in gynecological laparoscopic surgeries. The recruited sample will be randomly distributed in three groups to receive placebo, transverse abdominal plan block or quadratus lumborum block, in a covert way for the patients and team. The primary outcome evaluated will be the postoperative consumption of opioid and the secondary outcome will be the evaluation of postoperative pain scores.
This study evaluates the analgesia induced by suprascapular nerve block in comparison to interscalene nerve block in arthroscopic rotator cuff repairs. The experimental and the control group will receive the suprascapular nerve block and interscalene nerve block, respectively.
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a significant threat to global health. As the disease progresses, a series of acute complications tend to develop in multiple organs. Beyond the supportive care, no specific treatment has been established for COVID-19. The effectiveness, both short-term and long-term, of some promising antivirals, such as the hydroxychloroquine combination with azithromycin, needs to be evaluated. This study aims to investigate the predictive role of cardiac biomarkers and pulmonary symptoms for late complications of COVID-19 coronavirus infection on the heart and lung in patients treated with the hydroxychloroquine / azithromycin combination therapy. Thus, COVID-19 coronavirus patients undergoing hydroxychloroquine / azithromycin combination therapy will be compared to patients not undergoing this therapy. The comparison will be made by the analysis of the relationships between (1) levels of ultrasensitive cardiac troponins collected at the beginning of the infection and cardiac magnetic resonance data in the 3rd and 12th months of troponin collection and (2) findings CT scans and the results of the ergospirometers tests performed in those same periods. It is expected to demonstrate that: (1) cardiac troponin and lung tomographic findings can predict late complications of COVID-19 coronavirus infection in the heart and lung, assessed by cardiac magnetic resonance and ergospirometers one year after the beginning of the infection, and (2) hydroxychloroquine / azithromycin combined therapy can abolish the onset of these complications late. Furthermore, the results may point to the need for more rigorous monitoring of cardiologists and pulmonologists of these patients, due to the risk of hemodynamic complications, arrhythmogenic and respiratory.
The aim of this study is to evaluate the efficacy and safety of MTX-loaded nanoparticles in three different doses to treat severe COVID-19 patients.
The aim of study is to investigate gait in active elderly people regarding the kinematic parameters of gait, indicators of physical fitness and quality of life.
Neural control of posture depends on interaction of sensory and motor information from multiple structures, including the primary motor cortex (M1). Transcranial direct current stimulation (TDCS) improves postural control in children and adults with and without neurological disorders, however, additive effects to physical therapy treatment are still unknown, specifically balance exercises for children with balance deficit. The aim of this study is to identify the effects of adding anodic TDCS over M1 to exercises on postural control of children with balance deficit. This is a randomized, double-blind, controlled clinical trial.
