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.
Muscle strength is an important indicator of overall health and is a factor that has been associated with increased mortality in critical patients. Its measurement must be reliable and reproducible to ensure a quality outcome for clinical applicability. Recently, the use of digital handheld dynamometers in intensive care has gained support; however, analysis becomes challenging due to the absence of standardized reference equations for the Brazilian population. The aim of this study is to develop reference equations for the Brazilian population and define specific cutoff points for men, women, healthy individuals, and critical patients.
Introduction: Pain is one of the main complications in the immediate postoperative period that can harm the patient and can be managed through pharmacological and non-pharmacological methods. Complementary Integrative Health Practices are non-pharmacological methods that use therapeutic resources based on traditional knowledge to treat symptoms. Among them, aromatherapy stands out, which consists of the use of essential oils through inhalation or topical application for therapeutic purposes and which can be used as a nursing intervention, especially in the context of perioperative care. Objective: To evaluate the effect of aromatherapy on postoperative pain in adult patients in the immediate postoperative period. Method: This is a randomized controlled clinical trial that will be carried out in a teaching hospital. The project was submitted to the Research Ethics Committees of the School of Nursing of the University of Sao Paulo and the University of Sao Paulo Hospital. Adult patients undergoing elective surgical procedures of any surgical specialty under anesthesia of any type will be included. Individuals diagnosed with dementia, cognitive impairment or chronic pain will be excluded; individuals with a history of asthma, allergic bronchitis, chronic obstructive pulmonary disease, contact dermatitis or allergy to cosmetics with lavender fragrance, or hypersensitivity to the compounds used in the intervention; procedure for reoperation for any reason. The intervention will consist of the application of aromatherapy with 2% lavender essential oil through the skin and inhalation by a nurse, associated with usual care, in the immediate postoperative period; the placebo group will only receive the application of grape seed vegetable oil associated with usual care. A numerical verbal scale will be applied to assess pain and vital parameters will be measured upon patient admission, every fifteen minutes in the first hour and every thirty minutes in the second hour or after 15, 30, 45, 60 minutes, 1h30 minutes and 2 hours after applying the intervention, in the post-anesthesia recovery room. Possible associations between variables will be verified using Pearson's Chi-square or Fisher's exact tests. Comparison between means or medians will be made using the Student's t or Mann-Whitney tests, depending on the normality determined according to the Kolmogorov-Smirnov test. The significance level adopted will be 5%.
The purpose of this study is to evaluate the efficacy of lepodisiran in reducing cardiovascular risk in participants with high lipoprotein(a) who have cardiovascular disease or are at risk of a heart attack or stroke. The study drug will be administered subcutaneously (SC) (under the skin).
The primary objective of this study to evaluate the efficacy of ravulizumab compared with placebo to reduce proteinuria and slow the rate of eGFR decline in adult participants with IgAN who are at risk of disease progression.
The goal of this observational and prospective study is to investigate changes in physical performance, lung function, respiratory and peripheral muscle strength in patients during the postoperative period following pulmonary endarterectomy (PET).
Type 2 diabetes mellitus (T2DM) is one of the most important risk factors for atherosclerotic heart disease. Strategies focused solely on glycemic control have failed to demonstrate vascular events reduction in this population. On the other hand, new antidiabetic drugs recently have demonstrated significant decrease of cardiovascular mortality, raising the hypothesis that possible effects beyond glycemia control could explain this benefit. Aim: This study is intended to evaluate possible pleiothropic effects of dapaglifozin, a SGLT-2 (sodium glucose cotransporter 2) inhibitor, in individuals admitted with a diagnosis of Acute Myocardial Infarction (AMI). Methods: This is a prospective, randomized, double-blind, placebo controlled trial. Individuals presenting with AMI whithin the first seven days of evolution will be randomized to dapaglifozin or placebo. The investigators's goal is to analyze platelet aggregability 48 hours after randomization (primary endpoint), as well as glycemic control, cardiac biomarkers, corrected QT interval electrocardiographic analysis, autonomic modulation through spectral analysis of the RR interval and inflammatory biomarkers at inclusion and 30 days after starting study drug (secondary endpoints). Sample size calculation resulted in 80 individuals (40 per group). Expected results: This study will seek to aggregate new insights to the current knowledge about this new antidiabetic drug class. Previous randomized clinical trials have demonstrated that SGLT-2 inhibitors significantly reduced the composite endpoint of cardiovascular death, AMI or stroke, as well as Heart Failure (HF) hospitalization. Therefore, this study is supposed to clarify possible mechanisms that could explain these results aforementioned.
Chronic kidney disease (CKD) patients often present systemic inflammation and oxidative stress, resulting in metabolic disorders and high rates of disease-associated cardiovascular death. The literature has indicated that dietary control, the use of bioactive compounds, and the practice of regular physical exercise are essential for the prevention and management of CKD and its complications. In this context, beetroot (Beta vulgaris rubra) deserves attention as it is a source of several bioactive compounds, such as nitrate, betaine, and betalain, with beneficial effects for CKD patients, including anti-inflammatory, antioxidant effects, reduction of blood pressure, and vasodilatory action. The antioxidant and anti-inflammatory properties, in addition to their vasodilatory and antihypertensive capacity, can make supplementation of beetroot an excellent nutritional strategy to help in the treatment of CKD patients. So, this research project will bring contributions to the scientific world, providing strategies for application in clinical practice and the care of patients with CKD, on the use of beetroot associated with an exercise protocol as a non-pharmacological strategy in modulating inflammation, oxidative stress, and improved functional capacity. Furthermore, when supplemented hours before physical training, has been identified as an important factor in improving performance in these activities. Therefore, this study aims to evaluate the effects of supplementation (acute and chronic) of beetroot extract associated with an exercise protocol on complications associated with CKD.
This is a prospective observational study enrolling People Living with HIV (PLHIV) who are on a Dolutegravir-based AntiRetroviral Treatment (ART) regimen and experiencing virologic failure. Virologic failure is defined as two consecutive viral load measurements of >1000 copies/mL of blood. The main aim of the study is to identify the drug-resistance mutations in the viral genome that are associated with this failure. To achieve this goal, patients fulfilling the eligibility criteria will be invited for a single study visit for the collection of blood. The extracted HIV virus will be sequenced through whole genome sequencing methods to identify the drug-resistance mutations. The study is conducted in 15-20 countries within six regions of the IeDEA cohort (International epidemiology Databases to Evaluate AIDS).
This study will evaluate the effect of triple ICS/LAMA/LABA therapy with BGF MDI 320/14.4/9.6 μg on cardiopulmonary outcomes relative to LAMA/LABA therapy with GFF MDI 14.4/9.6 μg in a population with COPD and elevated cardiopulmonary risk.
Introduction: Adequate blood pressure control is necessary to reduce the risk of mortality from cardiovascular events. The effects of aerobic exercise on systemic arterial hypertension are already well known, however, to date, there is little evidence regarding the effect of an isometric exercise session for the lower limbs on blood pressure levels, especially when performed in elderly hypertensive individuals. Objective: To verify the effect of an isometric or aerobic exercise protocol for the lower limbs on 24-hour ambulatory blood pressure in elderly hypertensive individuals.
