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 study aims to evaluate the influence of age and sepsis on in vivo activity of OATP1A2 using rocuronium (ROC) as a probe and evaluating the pharmacokinetics and pharmacodynamics in ASA I-III surgical patients. Thus, adult patients without sepsis (control group, n= 12), adult patients with sepsis (sepsis group, n= 12) and elderly patients without sepsis (elderly group, n= 12), all submitted to small to medium-sized surgeries who were induced with individual doses of rocuronium, fentanyl and propofol are being investigated.
This study seeks to better characterize relationships between visual function and the progression (worsening) of geographic atrophy (GA) due to age-related macular degeneration (AMD). The study also will generate new information on the relationship between genetics and GA progression. This is a global, prospective, multicenter, epidemiologic study enrolling 200 participants with GA secondary to AMD. The study visits are scheduled to occur every 6 months. The anticipated duration of the study is up to 60 months.
Nowadays, the research priority in low back pain area have been find subgroup of patients with the same characteristics that might achieve better outcomes in a specific intervention. However, even though the studies in this area have increased, questions of this nature remaining without an adequate answer, or with limited evidence. Therefore, the investigators propose to examine the ability of clinical tests, developed to assess alterations related to clinical lumbar instability, to identify subgroups of patients with non specific chronic low back pain that may have better outcomes after a motor control exercises intervention.
This trial will enroll patients that have been diagnosed with a transient ischemic attack (TIA) or minor stroke that has occurred within the past 12 hours. Anyone diagnosed with a minor stroke faces the possibility of long-term disability and even death, regardless of treatment. Stroke symptoms such as weakness, difficulty speaking and paralysis may improve or worsen over the hours or days immediately following a stroke. TEMPO-2 is a minor stroke trial for patients presenting within 12 hours of their symptom onset. Patients will be randomized to TNK-tPA or standard of care. In the intervention group TNK-tPA is given as a single, intravenous bolus (0.25mg/Kg) immediately upon randomization. Maximum dose 50mg. The control group will receive antiplatelet agent(s) as decided by the treating physician. Antiplatelet agent(s) choice will be at the treating physician's discretion. TEMPO-2 Coordinating Centre is located in Calgary, AB, Canada. There will be approximately 50 sites participating worldwide. Dr. Shelagh Coutts is the Principal Investigator.
Previous studies found important function of brain in exercises regulation on healthy and athlete patients and this studies showed not invasive stimulation on temporal cortex brain, induces electrics field to insula cortex, in addition modulate autonomic nervous system cognition efforts during submaximal (maximal hight frequency) and maximal exercises. Measure immediate effects of transcranial stimulation in bloodstream (tDCS) anodic on right and left temporal cortex in the cardiorespiratory parameters (functional capacity, perception of efforts and modulation of autonomic nervous system) in patients with hemiparesis due stroke. Methods and Material: It Is a clinical trial, controlled and Double blind, using 30 adult patients with stroke sequel, like roam. Evaluation will be hemodynamic measure data such as: Heart Rate, Respiratory Rate, Blood Pressure, Lung Capacity Vital and assessment of the Autonomic Nervous System, before and after anodic electro stimulation from bloodstream on right and left temporal cortex region (T3 area) and cathodic position in contralateral supraorbital region to anode (Fp2). On temporal cortex will be applied of 2mA during stimulation of 20 minutes. Sham stimulation all electrodes Will be used. The stimulator turns on for 30 seconds. Results: The primary results will analyze cardiac frequency before and after tDCS and second step will assess the travelled distance on walking test for 6 minutes with and without tDCS and compare these respiratory reviews results with stroke gravity.
This study evaluates the effect of jaw exercise therapy in the treatment of temporomandibular disorder patients (TMD). An eligible group of patients will be treated with that therapy (experimental group) and another group will be treated with counseling and occlusal splint (control group), considered the standard therapy for TMD.
Eclampsia is an obstetric emergency capable of prophylaxis. To prevent and control seizures, there is no doubt that the magnesium sulfate (MgSO4) is the ideal drug. However, there are still questions regarding its use and dose. The scheme and the optimal time of administration remain to be elucidated. The objective of this trial is to compare the effectiveness and safety of intravenous magnesium sulfate in the maintenance phase 1g / h versus 2 g / h to prevent eclampsia in pregnant and postpartum women with severe preeclampsia (pure or superimposed).
The main purpose of this study was to demonstrate superiority with regard to overall survival of avelumab versus docetaxel in participants with programmed death ligand 1 (PD-L1) positive, non-small cell lung cancer (NSCLC) after failure of a platinum-based doublet.
For odor control malignant wounds (MW), use is 0.8% metronidazole solution - second recommendation scientific and clinical practice. But no this formulation available in Brazil , and its application to nursing steeps metronidazole tablets , diluted in saline and applied to the bed of (MW) . Thus , it is used off label for metronidazole ( tablets orally applied via " topical " - but it is not intact skin or mucosa ) , nursing and eventually manipulate the solution at bedside , and by law this power is pharmacist bedside and can not be taken . Family antiseptic chlorhexidine was developed with the purpose of use in infected wounds called polihexanide ( PHMB ) . In Brazil is now available for hospital and home care ( 0.2 % Aquasept ® ) use. Evidence reported positive results in controlling infection of chronic wounds such as pressure ulcers . Although not tested its efficacy in odor control. Thus the study aims to compare metronidazole solution 0.8 % versus 0.2 % PHMB in odor control , where , if the results are favorable to PHMB we have a treatment option in odor control with ready to use formulation and easy access . Evaluate and compare the effectiveness of metronidazole solution 0.8% and polihexanide solution (PHMB) in odor control in MW. Aims: Evaluate and compare the time needed for odor control (reduction in days), using metronidazole and PHMB in MW (primary endpoint); Evaluate and compare the perceptions of patients, nurses and researcher on the odor MW, using metronidazole and PHMB in the MW; Evaluate and compare the pain reported by patients during dressing changes, using metronidazole and PHMB in the MW; Evaluate and compare the quality of life of patients before and after the use of metronidazole and PHMB in MW. This is a randomized, double -blind study with patients diagnosed with cancer and patients with MW with odor clinical trial . The sample consisted of 24 subjects divided into 2 groups (control - metronidazole group and experimental group - PHMB ) , recruited in one cancer hospital in the city of São Paulo (AC Camargo Cancer Center), which has as protocol description in odor control MW metronidazole . After acceptance by the subject and return the Statement of Informed Consent signed , randomization will be done . For blinding , 0.8 % metronidazole solution will be provided by a compounding pharmacy (after stability testing of tablet diluted - and then stipulated expiration date) , and PHMB be bought from the supplier , delivered to the same compounding pharmacy which stores the PHMB in identical bottles to metronidazole ( only the responsible researcher will know to which group the subject was randomized ) . The evaluation of the odor will be taken by 3 " employees " and the patient through 3 scales at zero , four, eight and twelve days ( or earlier if classified as " odorless " by 3 reviewers and the patient ) . Two scales about painful sensations in exchange for healing , one on quality of life will be applied to the patient and a specifically on the impact of odor on the subject's life. To meet the proposed objectives, the data will be analyzed by: Friedman test to assess the odor reduction with respect to time; Mann-Whitney (or t test) for comparison of groups and the Fisher exact test to compare proportions. Data will be presented in the form of frequency tables for categorical variables and means, standard deviations and position measurements for quantitative variables. Will also be performed non-parametric analysis of ordinal data, or parametric analysis with Generalized Estimation Equation for binomial variables, depending on the data distribution and the sample size.
Aim: To compare prospectively two bariatric surgery techniques: sleeve gastrectomy (SG) vs gastric bypass (GB) in the evolution of nonalcoholic fatty liver disease (NAFLD) measured by the transient elastography in the first year. Methods: This is a randomized clinical trial with morbidly obese patients, between 18-60 years old from a Federal Hospital, Ministry of Health, Brazil. Patients were divided into 2 groups: group 1 - SG (n = 30) and group 2 - GB (n = 30). The randomization was made by lots. In the GB the investigators created 30 ml pouch, with a pancreatic and an alimentary limb of 1 meter, and a calibrated gastroenterostomy (1.5 cm diameter). In SG the investigators calibrated the gastric tube with a bougie number 32 (70 ml). The variables were compared one week before surgery and in the postoperative time (1, 3, 6 and 12 months). The variables were: patient anthropometry, laboratory tests and the transient liver elastography.
