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.
Multinational, multicentre, non-pharmacological intervention, cross-sectional and longitudinal study.
Diabetes and obesity affect many people in different countries. Similarly, millions of people have some type of gum disease such as gingivitis. The present study was conducted to clarify if systemic conditions such as diabetes and obesity could impair the response to gingivitis treatment. Subjects with gum disease showing diabetes type II (from 40 to 50 subjects), slight to moderate obesity (from 40 to 50 subjects) or its combination (from 40 to 50 subjects) were selected for the present study. In addition normal-weight subjects with gum disease (from 40 to 50 subjects) besides a group without gum disease (from 40 to 50 subjects) were selected for comparisons. After verbal and written explanations about the study, subjects who matched study criteria and who signed the informed consent form underwent full oral examinations in two separate visits. In the first visit, after a clinical examination to verify the levels of gingival inflammation and the accumulated amounts of dental plaque, the bone height was determined by X-Ray examinations. Bad breath was also evaluated by a chair-side apparatus. Additional laboratorial examinations included a) quantification of bacteria that cause gum disease from dental plaque samples, b) quantification of inflammatory products from gingival fluid sampling and c) quantification of produced saliva. Self-report questionnaires were used to check the impact of oral condition and treatment of gum disease in quality of life and individual daily performance. These examinations were repeated 3 months after dental treatment. All subjects received ultrasonic dental prophylaxis for cleaning their teeth. Based on systemic/oral conditions each group rinsed either an essential-oils containing mouth rinse or a placebo rinse. First rinse was supervised and the other ones were performed at home twice a day for three months. Each participant also received a toothbrush, a dental floss and a fluoride toothpaste monthly after oral hygiene instructions. Adherence to the treatment and occurrence of undesirable side effects were monitored throughout the study.
The purpose of this study is to assess the efficacy of the McKenzie method in patients with chronic non-specific low back.
The purpose of this study is to evaluate the effects of airway bilevel positive pressure on the improvement of exercise tolerance in patients with decompensated heart failure.
Mechanical ventilation is widely used for ICU patients as a lifesaving procedure. However, it is associated with several complications, such as ventilator-associated pneumonia and the increase of hospital morbidity and mortality. To avoid such complications, we need to wean these patients off the ventilator as soon as possible. This must however be done at the right time to avoid other complications, such as the need for re-intubation. For this reason, it is important to have a specific weaning protocol, which will reduce the time on mechanical ventilation, and avoiding the need for re-intubation and other complications. Recently, an argument has developed as to which weaning protocol would be more appropriated, and whether a computer driven weaning protocol could have better results than the conventional weaning protocols focusing on daily screening and daily interruption of sedation followed by a spontaneous breathing test. Our objective is to compare mechanical ventilation times, weaning success up to 48 hours after extubation, re-intubation rates between a group with computer driven weaning protocol (SmartCare) versus a weaning protocol with daily weaning screens and spontaneous breathing trials in ICU patients ventilated for more than 24 hours.
Some studies reported that selenium status is associated with cognitive function. However only a few reports have investigated whether selenium supplementation can benefit cognitive performance and in most of them selenium supplementation was not exclusive. Also, none of those reports have used foods rich in selenium as a source of supplementation. Thus, the aim of our study was to investigate whether the consumption of Brazil nuts improves cognitive function. We hypothesized that the daily consumption of Brazil nuts would have benefits on selenium status, increase antioxidant enzyme activity and improve cognitive function in older adults with MCI.
The purpose of this study was to offer patients who had participated in one of the phase II PK or phase III studies on FK506E (MR4) the possibility to continue FK506E (MR4) until commercial availability of the drug and to record long term efficacy and safety data.
The purpose of this study is to compare the effects of mental practice, associated with physical practice, on gait (cinematic parameters and mobility) in individuals with idiopathic Parkinson's disease. It is believed that familiarity with the normal gait pattern, associated with mental practice and physical practice can trigger significant changes in spatiotemporal and angular parameters that are not observed in the group not submitted to mental practice.
The study aimed to evaluate the chronic effects of Mat Pilates Training on blood pressure, heart rate, double product and psychobiological factors in hypertensive medicated women and acute effects of Mat Pilates Exercise on blood pressure of such individuals.
The purpose of this study was to evaluate the 6-month outcomes of applying low-intensity laser therapy associated with connective tissue grafts to treat gingival recession.
