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 epoetin is a glycoprotein and endogenous hormone, which is primarily synthesized by specific epithelial cells lining the kidney peritubular capillaries, and regulates continuous formation of red blood cells. This is a pharmacokinetics and pharmacodynamics study, in which each subject will receive the investigational product in different periods, as randomisation (Teste or Comparator). The evaluation of the profile included serum dosage of medications and reticulocyte count in peripheral blood.
Postoperative delirium is an acute mental syndrome that is caused by diffuse cerebral dysfunction resulting from the action of predisposing and precipitating factors acting together. It is associated with an increase in mortality and postoperative morbidity and prolongs the period of hospitalization of the patient Videolaparoscopic surgery has been increasingly used as a therapeutic and diagnostic method. In order to have a good visualization of the anatomical structures on which it will act, it is necessary to introduce gas into the cavity, a mandatory component known as pneumoperitoneum. This technique gives special characteristics for the conduction of anesthesia, since the positive intra-abdominal pressure results in changes in the patient's physiology. Some types of laparoscopic surgery require the position of Trendelenburg for better visualization of the operative field. Among the changes related to this position are the increase in cardiac output and intracranial pressure. In order to optimize the anesthetic procedure, anesthetic blocks have been increasingly used, especially the spinal. The association of general anesthesia with spinal anesthesia, followed by its contraindications is advantageous, because lower doses of anesthetic agents are necessary for the maintenance of general anesthesia. This association results in an earlier awakening, a reduction of nausea / vomiting, postoperative pain, length of hospital stay, cost effectiveness and greater patient satisfaction. As a disadvantage, by associating general anesthesia with spinal anesthesia, patients become susceptible to the adverse events of spinal anesthesia. Among these, the most common are headache, hypotension, nausea and vomiting, pruritus, urinary retention and tremor. Performing spinal anesthesia with opioids alone, without the use of local anesthetic is also possible, with morphine being the most used. The benefit of this variation of technique is analgesia for a period of 12 to 24 hours, without the cardiovascular consequences resulting from the action of the local anesthetic. JUSTIFICATION: There are no studies in the literature evaluating The objective of this study is to analyze if the anesthetic techniques employed, general anesthesia or general anesthesia associated with subarachnoid block, for videolaparoscopic oncologic surgeries, in Trendelenburg position, differ in relation to the incidence of delirium in the postoperative period.
The differential diagnosis of central diabetes insipidus (cDI) is difficult and the current test with the highest diagnostic accuracy is copeptin measurement after hypertonic saline infusion (HIS). Although the HIS improved diagnostic accuracy compared to the standard water deprivation test used for decades before, it still comprises great discomfort for patients due to the rise in serum sodium levels above 149mmol/l and requires the presence of medical staff at all times to guarantee safety of the test. The arginine stimulation test is routinely used to stimulate growth hormone. Own data in 52 patients with polyuria / polydipsia syndrome showed that arginine infusion is a potent stimulator of the neurohypophysis and provides a new diagnostic tool in the differential diagnosis of cDI. Copeptin measurements upon arginine stimulation (CAS) discriminated patients with diabetes insipidus vs. patients with primary polydipsia with a high diagnostic accuracy of 94%. To validate these results and to compare them against the HIS a large multicenter trial is needed, where the diagnostic accuracy of the CAS is compared to the HIS.
The purpose of this study is to compare the efficacy of ibuprofen, acetaminophen, chewing gum in reducing orthodontic pain. This study include 81 patients to be classified into 4 groups of 19 each: ibuprofen (400 mg), acetaminophen (500 mg), chewing gum and control. The patients in each group will receive 1 method immediately after placement of the initial archwire and every 6 hours for a week if they experiences pain. Pain perception will be recorded by the patients while jaw rest position and fitting back teeth at 2 hours, 24 hours, 2 days, 3 days, 7 days and 21 days after archwire placement, using a visual analog scale.
The purpose of this trial is to investigate the mechanisms leading to weight gain during CPAP treatment for obstructive sleep apnea (OSA).
The purpose of this study is to termine if a different attentional focus would alter the motor control in cervical muscles during the cranio-cervical test.
Providing high quality care for dying patients and their families is very important. One way one can assess the care provided is to ask bereaved relatives to complete a questionnaire after their family member has died. The questionnaire can ask about their experiences and their thoughts about the care provided to their family member. One such questionnaire is the 'Care Of the Dying Evaluation' (or CODE). CODE has been developed with the help and support of bereaved relatives and has been used extensively within the United Kingdom. In this project the investigators want to use the CODE questionnaire to look at bereaved relatives' views about care provided in seven different countries within Europe and Latin America. In the first part of the project CODE was translated into the main language of each country. Volunteers and bereaved relatives in each country were asked to give feedback about whether CODE was easy to understand, sensitive, and easy to complete. Based on the feedback a common version of CODE that is suitable for use across all the countries was developed. In the next phase of the project, relatives who have recently experienced a bereavement where one of their family members has died from cancer in a hospital, will be invited to complete the CODE questionnaire about two months after the patient's death. The relatives may complete CODE on paper, using a computer, or by interview. The aim is to have 100 completed CODE questionnaires from each of the seven countries. The data from the questionnaires will be used to make a report on the current quality of care for dying cancer patients in hospitals across the seven countries. It will also be possible to compare the care between the countries and identify areas needing improvement. In the next phase of the project, health care professionals, researchers and bereaved relatives together will use their knowledge and experience to find effective ways to improve the weak areas identified, and assess the results of putting these changes into practice.
Recent studies have shown positive results in the application of phototherapy for the improvement of performance and acceleration of the healing process of the body homeostasis. Among the methods used to assess the recovery post-exercise has cardiac autonomic modulation assessed by heart rate variability (HRV), a tool widely used in sports to evaluate medium global behavior of the autonomic nervous system. Objective: analyze and compare the effect of a special protocol of phototherapy using different light sources interacting with a combined training with an autonomic modulation of heart rate in different moments (baseline; tracking daily; recovery post-exercise and after training). Method: 45 male participants will be allocated from a stratified randomization into three groups: control (n=15), placebo (n=15) and group special protocol of phototherapy (n=15). Participants will perform a combined training of sprints and squats twice a week for twelve weeks divided into two phases. The application of phototherapy and placebo was administered in phase 2, after sprints and just before the squat. The phototherapy was used combine different light sources and wavelength (red and infrared). Was analyze HRV in five moments: baseline; traking daily; week target of phase I and II; after training. The weeks target consist of training sessions with greater energy expenditure (largest intensity). The sphericity of the data was tested by Mauchly test. In case of violation of the sphericity assumption, the correction of Greenhouse-Geisser was performed. The data was analyzed using analysis of variance for repeated measures (Bonferroni post-test), which provide information on the effects of time, group and interaction. All statistical analyzes assume the significance level of 5%.
The purpose of this study is to 1) evaluate the safety and tolerability, and immunogenicity of blinded V114 and Prevnar 13™ within each vaccination group, and 2) evaluate the safety and tolerability, and immunogenicity of PNEUMOVAX™23 (administered as open label, 12 months after allogeneic hematopoietic stem cell transplant [allo-HSCT] in participants who do not develop chronic graft-versus-host disease [GVHD]).
As part of the ZOSTER-006 and ZOSTER-022 pivotal trials of the HZ/su vaccine, all study participants completed quality of life (QoL) questionnaires. The only questionnaires encoded into the data base were those from participants who developed a suspected shingles episode during the study. The purpose of this study is to allow for the encoding and analysis of questionnaires for all subjects enrolled in ZOSTER-006 and ZOSTER-022. The aim is to assess the baseline frailty of subjects enrolled in these studies and to investigate whether this population is representative of the general population.
