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 aim of the study is to verify the effect of HAART in critically ill HIV infected patients. The current practice is to begin antiviral therapy after ICU discharge, when the condition of the patient is more stable. The investigators hypothesis is that the investigators can improve outcome of these patients with earlier antiviral therapy in the ICU. The investigators just have retrospective studies in this scenario. After admission to ICU, patients are assigned to one of two arms: early HAART (within 5 days of ICU admission) or conventional therapy (initiation of HAART after ICU discharge). The following data will be collected: demographic variables, CD4 count, viral load, drug toxicity, opportunistic infection, hemodialysis, mechanical ventilation and vasoactive drug. The patients will be followed to determine ICU mortality, hospital mortality and 6-month mortality.
Hypothesis: What is the best modulation of pulse frequency in transcutaneous electrical nerve stimulation in dysmenorrhea? Purpose: To determine the effect of hypoalgesia frequency modulation pulse by transcutaneous electrical nerve (TENS) in dysmenorrhea. Methods: A controlled clinical study and prospective developed at the School of Physiotherapy Clinic / UFPI. Forty students were randomized into four distinct groups of the modulation frequency TENS: group 1 - 100 Hz, 100μs, group 2 - 4 Hz, 100μs, group 3 - placebo (apparatus off), group 4 - placebo induced (2 Hz, 40μs). All were initially evaluated by a questionnaire developed for the study, the visual analogue scale (VAS) (before, after 20, 30, 40, 50, 60 minutes) and the McGill Pain Questionnaire (before and after 20 minutes). The total duration of TENS application was 20 minutes and all protocols were performed in a single session. The analysis of variance (One-way ANOVA) followed by the Tukey procedure was applied to identify differences between experimental groups for each variable analyzed. The level of significance was p< 0,05.
The aim of the trial is to investigate asthma control with 160 to 640 μg ciclesonide/day. Asthma control will be assessed by the Asthma Control Questionnaire (ACQ).
The primary objective of the study is to evaluate the long-term safety of recombinant human Factor VIII Fc fusion protein (rFVIIIFc) in participants with hemophilia A. The secondary objective of the study is to evaluate the efficacy of rFVIIIFc in the prevention and treatment of bleeding episodes in participants with hemophilia A.
The purpose of this study is: - To compare blood sugar control on LY2605541 with insulin glargine after 52 weeks of treatment. - To compare the rate of nocturnal low blood sugar episodes on LY2605541 with insulin glargine during 52 weeks of treatment. - To compare the number of participants on LY2605541 reaching blood sugar targets without low blood sugar episodes at night to those taking insulin glargine after 52 weeks of treatment. - To compare the rate of low blood sugar episodes on LY2605541 with insulin glargine during 52 weeks of treatment
Adequate pharmacological treatment controls symptoms in most asthmatics. Pressurized metered dose inhalers (pMDI)are the most used drug delivery devices. Valved holding chambers of different types and sizes have also been developed for use in combination with pMDI. The therapeutic efficacy of treatment depends on the amount of inhaled particles. The chambers can optimize lung deposition as it obviates lung-hand coordination and retain larger particles. The aim of this study is to compare the efficacy of the fine particle combination pMDI Beclomethasone/Formoterol in asthma control,with or without the aid of a spacer in patients without adequate asthma control on medium to high-dose inhaled steroids associated with long acting beta adrenergic drugs. The hypothesis is that there is no clinical efficacy difference between the two forms of drug administration.
Obesity is a chronic disease now considered a major public health concern in the global context, as it causes or exacerbates many diseases limitations in providing quality of life and higher treatment costs. The increase in the number of patients undergoing bariatric surgery and the excess skin and subcutaneous tissue adjacent to slimming collaborate in the search for growth by plastic surgery. Currently several techniques of thighplasty has been submitted but no studies were found that evaluated the characteristic clinical and emotional resulting from this procedure. This study has as a goal to evaluate the body image and quality of life in women submitted to thighplasty.
The purpose of this study is to evaluate the effectiveness of a brazilian cardioprotective diet plan to reduce cardiovascular risk factors of new cardiovascular events.
Several factors characterize repetitive transcranial magnetic stimulation (rTMS) as a strategic aid in the treatment of postpartum depression. However, up to current days there have been no studies evaluating the effects of rTMS on neurocognitive and social performance of women suffering from the disorder. The present study evaluates the impacts of rTMS in clinical, cognitive and social performance.
Introduction: Patients undergoing noncardiac surgery are at increased risk of cardiovascular complications. The development of methods that can accurately predict the occurrence of these events is of critical importance and large studies have been published with this purpose. Based on these studies, several algorithms have been proposed to predict of cardiovascular events postoperatively. However, quantification of this risk is often difficult to measure, especially in those patients with subclinical disease, not always detected in routine evaluation. The ankle brachial index (ABI) has proved a valuable tool in the quantification of cardiovascular risk, and perhaps the most promising when compared with other methods. It is easy, cheap, fast and feasible in office care, with a great acceptance between patients and small intra and inter observer variability. Despite strong evidence of the utility of ABI as a tool in assessing cardiovascular risk, there are no data about the use of ABI in other patients referred for non vascular surgery, which constitutes the majority of operations performed worldwide. Objectives: To evaluate the use of ABI as a predictor of cardiovascular events in patients undergoing non-cardiac and non-vascular surgery and its applicability as a tool in the reclassification of patient risk groups established by guidelines for perioperative evaluation. Methods: 300 moderate to high risk patients referred for non-vascular and non-cardiac will be included. Data about risk factors, signs and symptoms, physical examination and treatment used will be collected before surgery. The ABI will be measured and the patient will be monitored for 30 days to the detection of cardiovascular events: death from any cardiovascular causes, unstable angina, nonfatal myocardial infarction, isolated elevation of troponin, decompensated heart failure, cardiogenic shock, stop nonfatal heart failure, pulmonary edema, stroke and lower limb ischemia. Postoperative electrocardiogram, total creatine kinase, MB fraction and troponin I will be measured daily until 3º day and whenever clinically indicated.
