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.
This project aims to develop and evaluate the effectiveness of an Personalized Normative Feedback (PNF) intervention via the internet, through a randomized clinical trial for alcohol consumption among Brazilian college students, as well as evaluating the most effective components of the PNF (normative and list of consequences). The sample is composed of college students aged between 18 and 30 years. Participants allocated into four different groups: control, full intervention (PNF), feedback with normative components (FN) and feedback with list of consequences (FLC). The investigators will use the dismantling design to study the most effective components. Participants will be followed-up at 1, 3 and 6 months.
The purpose of this study is to provide access to continued treatment for subjects who participated in other Astellas sponsored trials and for whom the investigator feels the subject may benefit from continued treatment.
Introduction: As employees spent most part of their time at the worksite, it provides a venue to address multiple individual risk factors and promote health. The America Heart Association (AHA) defined cardiovascular health using as metrics smoking status, body mass index, physical activity, diet, total cholesterol, blood pressure and fasting blood glucose. Objective: Evaluate Bayer employees' cardiovascular health according to the AHA definition and the acceptance to engage in lifestyle change programs. Methods: By the time of the annual occupational safety periodic medical examination, employees will receive an email with information about the cardiovascular health screening, exams requisition (fasting blood glucose and total cholesterol) and a copy of the written informed consent. If the employee accepts to participate, after providing a written informed consent, he will be evaluated according to the AHA cardiovascular health metrics. Data will be collected at the occupational safety electronic health record. After medical evaluation, employees will receive a printed feedback with their cardiovascular health score and will be referred to indicated lifestyle change programs (healthy weight, smoking cessation, diabetes control, high blood pressure control, dyslipidemia control). After 12 months we will evaluate the percentage of employees who accept to participate; prevalence of the cardiovascular risk factors and distribution according to the AHA classification in ideal, intermediate and poor; adherence to lifestyle change programs.
Decrease in blood cell counts due to deficient bone marrow function, called bone marrow failure, as well as some lung diseases, called idiopathic pulmonary fibrosis, can be caused by genetic defects in telomere biology genes, eventually causing telomere erosion. These disorders are collectively termed "telomeropathies". There is evidence that male hormones may improve blood cell counts in marrow failure, and these hormones are able to stimulate telomerase function in hematopoietic cells in vitro. We propose this study to the use of male hormone in patients with aplastic anemia and pulmonary fibrosis associated with defects in telomeres.
To demonstrate the free combination of budesonide and indacaterol is as efficacious as fluticasone and salmeterol in patients with COPD
The purpose of this study was to compare the anesthetic efficacy of articaine, lidocaine and mepivacaine in patients with irreversible pulpitis of mandibular molar.
Vasopressin is a vasopressor used in patients with septic shock. However, its systemic hemodynamic effects and its microcirculation effects are not completely known and understood. This study aimed to evaluate the effect of exogenous vasopressin on sublingual microcirculation using the sidestream dark field technique and to correlate it with its systemic effects. To this prospective interventional study, patients with septic shock were included during the first 48 hours of use of catecholamine vasopressors, admitted to the intensive care unit of a university hospital. Vasopressin was administered at 0.04 U / min for one hour. Systemic hemodynamic measurements were obtained immediately before and 1 hour after vasopressin. In addition, images of sublingual microcirculation were collected through sidestream dark field technology. Further analysis with specific software was done after.
This open-label, randomized, 3-arm study will evaluate the efficacy and safety of (obinutuzumab) RO5072759 in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000 mg intravenous (iv) infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.
Coronary artery disease (CAD) and diabetes mellitus (DM) may promote alterations in heart responses during exercise or postural maneuver. Thus, the purpose of this study is to observe the influence of different postures (supine, seated and standing) and different percentages (15, 30, 45 and 60%) of the maximum voluntary contraction (MVC) of handgrip in the responses of heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), cardiac output (CO), stroke volume (SV) and peripheral vascular resistance (PVR) in coronary patients with and without type 2 diabetes.
The treatment of aggressive periodontitis (AgP) represents a challenge for clinicians, because there are no standardized protocols for efficient control of the disease. The aim of this study is to evaluate the effect of multiple applications of antimicrobial photodynamic therapy (aPDT) as an adjunct to non-surgical periodontal treatment (nsPT) in patients diagnosed with AgP. Twenty patients with a clinical diagnosis of AgP will be treated in a split-mouth design study to either aPDT associated with scaling and root planning (SRP) or SRP only. aPDT will be performed by using a laser light source with 690 nm wavelength associated with a phenothiazine photosensitizer. The applications will occur in four episodes (days 0, 2, 7 and 14). All patients will be monitored for 90 days. Clinical assessment of plaque index, probing depth, clinical attachment level and bleeding on probing will be performed at baseline (pre-intervention period) and 30 and 90 days after the nsPT. Subgingival plaque samples will be collected (at baseline and 30 and 90 days after the nsPT) and the counts of 40 subgingival species will be determined using DNA-DNA checkerboard hybridization. Gingival crevicular fluid samples will be collected (at baseline and 14, 30 and 90 after the nsTP) for evaluation the volume of fluid (Periotron) and the levels of Interleukin 1 beta, Interleukin 10 and Tumor Necrosis Factor alpha (Luminex). Data obtained will be statistically analyzed.
