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.
Background: There is controversy regarding the postoperative effects of periodontal dressing on the periodontium, pain and discomfort. The aim of the present study was to compare postoperative pain following surgical crown lengthening with and without the use of periodontal dressing. Material and Methods: A blind, randomized, clinical trial was carried out with 36 patients. Following surgical crown lengthening, the individuals were randomly allocated to the periodontal dressing group (PDG) and control group (CG - non-placement of periodontal dressing). Pain and discomfort were analyzed using a visual analog scale (VAS), verbal scale (VS) and the number of analgesics consumed in seven days postoperatively. Postoperative infection, stability of the gingival margin and type of healing were also evaluated.
Obstructive sleep apnea (OSA) can impars body weight reduction by changes in body composition and energy expenditure. The objective of this study is to evaluate the influence of OSA in energy metabolism and body mass loss in obese subjects. Ninety obese volunteers of both genders, 45 diagnosed with OSA and 45 without OSA, will be submitted to a dietary intervention of one months. Volunteers will be distributed into four groups: obese OSA PTN with moderate protein diet (1.6 g / kg protein / day), obese OSA CHO diet (0.8 g / kg protein / day) with standard composition diet, obese NSAOS PTN diet moderate in protein and CHO NSAOS obese standard diet. All groups will be instructed to perform a restricted energy diet (less 30% of daily energy expenditure). At baseline and one month after the beginning of the program the following evaluations will be conducted: total energy expenditure measured by doubly labeled water method, resting energy expenditure and thermic effect of food by calorimetry, polysomnography analysis, body composition by pletysmography, food consumption by three days of food diary, blood collection for analysis of lipid profile, visceral proteins, hormones related to control of body weight and inflammation. As hypothesis we believe that apneic obese individuals have greater difficult in weight loss and loss more free fat mass than the obese no apneic and that diets with more protein can contribute to greater weight loss, better body composition and energy expenditure in these population.
The purpose of this study is to evaluate the effects of Delafloxacin versus Vancomycin plus Aztreonam in the treatment of patients with acute bacterial skin and soft tissue infections.
The purpose of this study is to determine whether a pedometer-based unsupervised exercise program is more effective than a general exercise recommendation to increase lifestyle physical activity in adult patients with asthma.
The hypothesis of this study is to determine whether the technique of intramedullary locking nail presents clinical results comparable to the technique of locking plates, based on the Constant Score.
The aim of the proposed study is to evaluate the immediate effect of acupuncture on pain, cervical range of motion and electromyographic activity of the upper trapezius muscle in patients with nonspecific neck pain.Twelve patients with nonspecific neck pain and 12 healthy subjects will be enrolled in a randomized, single-blind, crossover study. Each patient will receive two forms of treatment in random order: a single session of traditional acupuncture and sham acupuncture. To eliminate carry-over treatment effects, a one-week wash-out period will be respected between sessions. Surface electromyography will be used to determine motor control in the upper trapezius muscle before and after treatment. The outcome measures in the group with neck pain will be a numerical pain rating scale (range: 0 [no pain] to 10 [maximum pain]), documentation of the pain area on a body chart and cervical range of motion. Linear regression analysis will be applied for each individual to investigate associations between the sEMG variables and force (excluding the sixth step). The slopes of the regression lines will be used to measure the sensitivity of the sEMG variables regarding changes in force. The Shapiro-Wilk test will be used to test the normality of the data distribution regarding RMS and MDF values in the third and sixth step of the step contraction. Paired samples (Student's t-test or Wilcoxon test) will be used to test differences between third and sixth contraction step. A mixed linear model will be used to analyze and compare the sEMG data during sustained contraction (five steps) between pre-acupuncture (EMG-1) and post-acupuncture (EMG-2) evaluations. These comparisons will demonstrate whether acupoints TE-5 and LI-11 affect the activity of the upper trapezius muscle, as hypothesized. The pain (NRS, PPT and area) and cervical ROM data collected during the four evaluations will also be compared using a mixed linear model. The Statistical Package for Social Sciences (SPSS, version 19.0 for Windows) will be employed for the statistical analysis, with the level of significance set to 5% (p < 0.05).
This clinical study is conducted to assess the efficacy of cadazolid compared to vancomycin in subjects with Clostridium difficile-associated diarrhea (CDAD).
The purpose of this study is to compare the effects of different trainings on cognition and physical performances in elderly over 80 years.
Endothelial dysfunction precedes the development of cardiovascular disease and it is common in patients with diabetes mellitus. The aim of this study is to identify the effect of two different physical training programs, using ultrasound techniques, on the endothelial function of patients with type 2 DM.
Carboxytherapy (CA) refers to the cutaneous and subcutaneous administration of carbon dioxide gas [CO2] for therapeutic purposes. Radiofrequency (RF) is a method that uses electric current to generate heat into the layers of the skin and the subcutaneous tissue. Both techniques are indicated to the treatment of skin laxity. The aim of this study was to compare the effects of CA an RF on human skin. Methods: Eight patients who underwent abdominoplasty surgery received a single procedure of both treatments. Untreated skin was used as control. In an area of 49 cm2 (7 x 7 cm) in the infra-umbilical region CA was performed on the right and RF on the left side. Sample collection period ranged from zero to 120 days. CA was administered at a velocity of 40 ml/min, and the total quantity of CO2 infused was approximately 20ml. RF was carried out in a temperature higher than 40ºC on the epidermis for 5 minutes after reaching this temperature.
