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 purpose of this study is to assess the effect of canagliflozin relative to placebo on glycated hemoglobin (HbA1c) after 26 weeks of treatment, and to assess the overall safety and tolerability of canagliflozin.
Introduction: Sleep disturbances may contribute to impairments in mood, occupational and intellectual performance, and social relationships, as well as being associated with cardiovascular diseases, such as arterial hypertension. Sedentary lifestyle has often been associated with poor sleep quality and hypertension; regular exercise has been studied as a coadjuvant therapy for hypertension and/or for some sleep disorders. Objective: To compare sleep pattern of active and inactive patients with arterial hypertension, as well as to evaluate complaints of depression and anxiety, and the mood profile. Material and Methods: Polysomnography, Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale will be used to assess the sleep pattern. Depression will be assessed by the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) anxiety, and mood pattern by the State of Mood Profile (POMS). The level of physical activity will be recorded by the number of steps taken (pedometer). Participating in the study will be 60 hypertension patients (ACTIVE, n=30; INACTIVE, n=30). Hypothesis: Active hypertensive patients better quality of sleep, better mood profile, and fewer complaints of depression and anxiety when compared to physically inactive hypertensive patients.
Patellofemoral Pain (PFP) is one of the most common disorders that affecting the physically active population, and its incidence is higher among women. Despite the high incidence, the etiologies of this painful syndrome are still unclear. Research has verified the influence of hip stabilizers on knee injurie and has demonstrated a deficit of strength of the hip lateral rotator, abductors and extensors muscles in patients with PFP. The aim of this study is to compare the effectiveness of strengthening the Posterolateral Hip Complex with the Anteromedial Hip Complex associated with quadriceps strengthening for pain reduction and improvement of functional capacity in patients with PFP.
The purpose of this Phase 2, multicenter, randomized, placebo-controlled, double-blind study to evaluate the efficacy and safety of an oral treatment regimen of CC-220 versus placebo in adult subjects with active systemic lupus erythematosus. Approximately 280 subjects with a documented diagnosis of SLE will be randomized 2:2:1:2 to receive CC-220 (0.45 mg QD, 0.3 mg QD or 0.15 mg QD) or identically appearing placebo.
The investigator will investigate the effects of higher protein/amino acid dosing (≥2.2 g/kg/d) vs usual protein/amino acid dosing (≤1.2 g/kg/d) on clinical outcomes in nutritionally high risk ill patients.
Introduction: The prevalence of chronic insomnia in the general population is between 10 and 15%. The therapy commonly prescribed for its treatment is pharmacological, however, there are several non-pharmacological alternatives being studied, among them physical exercise. Although some studies have described the effect of exercise on sleep in insomnia, there are no studies comparing exercise and drugs in the treatment of chronic insomnia, or its effect as coadjuvant therapy. Objective: To compare the acute and chronic effects of aerobic exercise and zolpidem on sleep quality, mood and quality of life in patients with chronic insomnia. Material and Methods: 30 patients with chronic insomnia will be randomly assigned into two groups: EXERCISE (n=15) or ZOLPIDEM (n=15). The patients of EXERCISE group will be included in an aerobic exercise program, performed in 50% of reserve heart rate, on a treadmill (50 minutes, 3 times/week), during 6 weeks. The ZOLPIDEM group will be treated with zolpidem (10mg/night) during 6 weeks. Polysomnography, actigraphy, sleep diary and questionnaires will be used the evaluate sleep pattern. Mood and quality of life will be investigated by POMS and SF-36 questionnaires. Hypothesis: Considering previous studies have demonstrated positive effects of aerobic exercise in the insomnia symptoms, the hypothesis of this study is that aerobic exercise, performed at moderate intensity, can control the symptoms of chronic insomnia similarly to pharmacological therapy.
Subclinical infection of the intervertebral disc after lumbar disc herniation surgery has been correlated to chronic low back pain and vertebral endplate changes. The most commonly reported agent is Propionibacterium acnes. However, the real incidence is unclear, as it has been reported in some series ranging from 3.7% to 46%. Recently, a systematic review concluded that there is a relationship between P. acnes and endplate changes, but, there are so far no studies to verify whether the reported presence of that pathogen in the intervertebral discs is due to local infection or whether intraoperative contamination occurred during the collection of samples. Thus, the main objective of this study is to estimate the incidence of subclinical infection in patients surgically treated for lumbar disc herniation. To this end, a prospective cohort study will be conducted with a minimum of 95 patients between 18 and 65 years of age who have been submitted to surgery after failure of conservative treatment. The extruded disc will be removed and cultured for bacterial identification. As controls, the ligamentum flavum and the multifidus muscle, taken respectively before and after removal of the herniated fragment will also be cultured. Patients will be followed-up for a year and MRI will be done at the end of this period.
Taurine is a nitrogenous compound, naturally present in heart, leukocytes, retina, central nervous system, especially in muscles. It has several beneficial physiological effects like antioxidant action, and could increase muscle force contraction and insulin sensibility. Triathlon is a sport of medium to high intensity, that can causes an increase in the rate of oxygen consumption during intense exercise and consequently increases free radicals production and oxidative stress, which may compromise an athlete's performance. Due to the weekly intense training, triathletes need nutritional care ranging from calories and nutrients adequacy to the use of specific nutrients that can help to maintain health. Thus, it is believed that the use of taurine associated with chocolate milk after exercise can promote general metabolic insulin action in order to favor carbohydrates metabolism regulation, assist muscle recover and prevent oxidative damage and thus promote triathletes performance and muscle mass gain. Thus, the aim of this project is to evaluate the effects of taurine and chocolate milk supplementation in body composition, athletic performance and oxidative stress in triathletes.
This study will be performed in people with obstructive sleep apnea, in which one group will receive treatment with cervical stabilization for six weeks and the control group will receive treatment after the interval of six weeks
