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 primary objective of this study is to determine if N-Acetylcysteine (NAC) has efficacy as an augmentation agent in the treatment of treatment-resistant obsessive-compulsive disorder (OCD). The investigators predict that NAC will reduce OCD symptoms after sixteen weeks of add-on treatment as measured by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).
The purpose of this study is to evaluate the efficacy of cortical stimulation (CS) as an adjunctive treatment for chronic neuropathic pain.
Pulmonary rehabilitation consists of a multidisciplinary program of care for patients with chronic respiratory disease, which currently encompasses numerous features and physical training methods aimed at maintaining stability clinic for people with Chronic Obstructive Pulmonary Disease (COPD), especially in patients who, even with optimized clinical treatment, continue their decline and symptomatic physical functions and 8 so that these social. goals are achieved the patient with COPD should integrate into a program of RP assiduous and with accompanying several times per week, for several months, which for a number of factors is not always possible. For this reason, it is the research of methodology of RP that hold their effectiveness, but with greater flexibility and viability to people with COPD. On this basis, this study aims to investigate the effectiveness of a program of RP semi-domiciliar in which the patient suffering from COPD can receive guidance and training in person, to develop it partially in own domicile.
The aim of this trial was to compare the effects of estradiol or genistein treatment on the hialuronic acid concentration on the postmenopausal facial skin. In this study, 30 postmenopausal women were evaluated through a prospective, randomized, double-blind trial. The volunteers were postmenopausal women treated in the Gynecology Department of the Federal University of São Paulo (UNIFESP). The participants were divided into two groups: group E, treated with 17 β estradiol gel 0.01% (n = 15), and group G, treated with genistein gel 4 % (isoflavones, n=15). The length of treatment was 24 consecutive weeks. Preauricular skin biopsies were performed on each patient before and after the treatment for evaluating hyaluronic acid in the tissue. The materials were processed through immunohistochemical and biochemical methods.
This study was designed to determine whether the duration of dressing wear following augmentation mammaplasty influence skin colonization and eventually surgical site infections rates.
There are two options of fetal treatment in cases of severe lower urinary tract obstructions: the vesico-amniotic shunting and fetal cystoscopy. There is no study confirming the effectiveness of these treatment, specially comparing both techniques. The present study aims to investigate the effectiveness of these treatments.
Objectives: To evaluate the effects of the technique of Breath Stacking (BS) in the distribution of ventilation in the chest in women with morbid obesity. Methods: Randomized clinical trial, blinded, and controlled with 32 women (BMI ≥ 40kg/m2), separated into two groups: control (GC) with n = 16 and 41.94 ± 9.38 years and group Breath Stacking (GBS) , n = 16 and 40.38 ± 10.16 years. Optoelectronic plethysmography (POE) was used to assess lung ventilation. For the BS technique was used to mask the expiratory branch occluded and Wright spirometer. GBS held three techniques with an interval of three minutes. The GC used the same circuit without the occlusion of the expiratory branch. Results: GBS was found to be higher in the contribution of tidal volume (VT) into the chest circumference (p = 0.04) and decrease in abdominal compartment (p = 0.03), whereas the CG showed no difference in distribution. Spirometric variables: FEV1 (%), FVC (%), FEV1/FVC (%), VC and CI showed no difference before and after the technical BS and GBS in the GC. Conclusions: The technique BS altered the distribution pattern of regional ventilation, resulting in greater contribution in lung volume in the lower rib cage, corresponding to activity of the diaphragm, with redistribution of volume between compartments.
This study main objective is investigating impulsivity on cocaine or crack addicts. The investigators main hypothesis is that different measures (such as scales or behavioral tasks, for example) of impulsivity may produce distinct outcomes, and they might also differ among cocaine (sniffed) and crack users. Thus, it would be of great value to compare such measures once these data are often interpreted as the same phenomenon.
This study aims to evaluate the possible Correlation Between Serum Levels of Markers of Neuronal Injury and Cognitive Dysfunction after Coronary Artery Bypass Surgery.
Improvements in diagnosis of dengue fever and prediction of which patients will get more severe disease are urgently needed to improve the treatment of patients with dengue. This is very important in places with many people who suffer from dengue but have limited health care resources. This study will enroll patients with fever which may be caused by dengue in 6 countries with high incidence of dengue over two continents (Brazil, Cambodia, El Salvador, Indonesia, Malaysia and Vietnam). All patients will be followed by a doctor with blood tests and exams until they recover. Symptoms and laboratory tests will be followed so that the cause of fever can be determined. For patients who have dengue, the investigators will look for symptoms and tests which indicate more serious disease. This study will help to determine how to identify patients with dengue fever based on symptoms and simple laboratory tests and those who will get more serious disease. It will also help to define a more standardized management of patients with dengue fever.
