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.
An intertrochanteric (ITF) trochanteric fracture of the femur is an exclusively extra capsular fracture in which the fracture line extends from the greater trochanter to the lesser trochanter. Its incidence has increased significantly over the past decades and is expected to double in the next 25 years, with an important global economic impact . It affects women in the seventh and eighth decades of life, an age group older than femoral neck fractures. For this reason, the mortality of intertrochanteric fractures is twice that of the femoral neck. The treatment is surgical, in which the objective is the stable internal fixation and the patient's early ambulation. Functional outcomes and treatment mortality are related including factors perioperative anemia and blood loss.Even so, even with these precautions, blood loss in this surgical procedure appears to be greater than expected, with blood loss of the order of 2100ml. Blood loss management and the inherent risks of anemia can be circumvented with blood transfusion. However, blood transfusion is not without risks and complications, such as hypersensitivity and hemolytic reactions, cardiac overload, infectious diseases. Homologous transfusions are associated with prolonged hospital stay, increased costs and increased patient morbidity and mortality. So, alternatives have been used to avoid the use of blood such as saline solutions, use of erythropoietin and antifibrinolytic agents . Tranexamic acid (TXA) is a drug that interferes with fibrinolysis, in use for more than 50 years in surgery, particularly in cardiac surgery. Only recently, TXA has sparked interest in orthopedic surgeries. Studies have shown the effectiveness and safety of TXA at FIT, but presented different forms of administration (intravenous, topical, infiltrative) . Despite promising results to contain bleeding in elective orthopedic surgery and fractures, in daily practice, TXA is not very popular, especially in fractures, and has not been used routinely by all doctors. Studies have not been found in the literature about the topical use of TXA compared to intravenous use in FIT.
Social distancing during the COVID-19 pandemic could lead to clinical and functional deterioration of people living with chronic respiratory diseases (CRD). As they are considered risk group for COVID-19, it is not recommended that they leave their house and have interaction with people outside. Thus, most of them have not been attend Pulmonary Rehabilitation sections since the beginning of pandemic, neither exercising outdoor, experiencing drastic restrictions in their activities of daily living. It is well known that low level of physical activity in daily life (PADL) in this population is related to poor prognosis, including higher chance of hospitalization due to exacerbation and mortality. Therefore, the aim of this study is to evaluate the short- and mid-term impact of the COVID-19 pandemic on the clinical, physical and functional conditions and the PADL level of people living with CRD (chronic obstructive pulmonary disease, asthma and interstitial lung diseases). Participants will be assessed during the social isolation period and they will be reassessed immediately after release from social isolation. Thus, the subjects will be followed-up during 12 months to record symptoms, functional status, quality of life, exacerbations and hospitalizations. The researchers' hypothesis is that those patients will present very low level of PADL in association to sedentarism, poor functional status, more symptoms of dyspnoea, anxiety and depression, poor sleep quality and, consequently, will present more episodes of acute exacerbation of the disease and more hospital admission during the study protocol.
The purpose of this study is to monitor short-term changes in tissue oxygen saturation and local blood flow as results of changing from supine to prone position in ARDS COVID-19 patients
The purpose of this study is to characterize microvascular reactivity on the forearm muscle using non-invasive near-infrared spectroscopy in critically ill COVID-19 patients, and to correlate its alterations with 28-day mortality in ICU COVID-19 patients.
This Phase I/II clinical study will evaluate the safety and efficacy of valoctocogene roxaparvovec in patients with severe haemophilia A and inhibitors to FVIII. Part A of the study will involve subjects who have active inhibitors to FVIII, and Part B involving subjects with a prior history of inhibitors.
Trastuzumab is an important treatment for HER 2 positive breast cancer. But trastuzumab can cause injury to the heart, and this is one of the main reasons it cannot be administered as planned. Heart injury can often be successfully treated using cardiac medications. The objectives of SCHOLAR-2 are to evaluate whether is it safe and effective to continue trastuzumab, pertuzumab or trastuzumab-emtansine (T-DM1) in patients with early stage HER-2 positive breast cancer despite mild, minimally symptomatic or asymptomatic systolic left ventricular dysfunction as compared with a guideline-driven approach of withholding or discontinuing trastuzumab, pertuzumab or trastuzumab-emtansine (T-DM1). In SCHOLAR-2, we will compare two thresholds of withholding or discontinuing trastuzumab/pertuzumab/trastuzumab-emtansine: a threshold that is currently advocated for by existing treatment practice guidelines versus a more aggressive threshold that allows trastuzumab/pertuzumab/trastuzumab-emtansine to continue at lower levels of LVEF than currently supported by guideline documents.
Systemic autoimmune myopathies are rheumatic diseases that affect the striatum skeletal muscles. The transcranial direct current stimulation technique has been frequent, for example, in patients with ischemic stroke or for the optimization of muscular performance in athletes. However, to date, there are no studies evaluating this technique in patients with systemic autoimmune myopathies. Therefore, the main objective of the present prospective, randomized, double-blind, placebo-controlled study is to evaluate the safety and efficacy of the application of chronic transcranial direct current stimulation sessions - associated with aerobic exercises - in the patients with systemic autoimmune myopathies.
Short-course radiotherapy followed by consolidation chemotherapy has shown a better response rate when compared to chemoradiotherapy treatment. In addition, recent studies have shown better tolerance with total neoadjuvant treatment, with induction or consolidation chemotherapy. Induction chemotherapy could reduce the size of the tumor, treat micrometastases early and allow treatment to start immediately (avoiding potential delays in waiting for radiotherapy). While consolidation chemotherapy allows longer waiting times for surgery, with higher response rates.
This is a phase 3 study to compare the efficacy and safety of HBI-8000 or Placebo combined with nivolumab on patients with unresectable or metastatic melanoma and eligible patients who are not adolescents or patients with new, progressive brain metastasis will be stratified by PD-L1 expression and LDH level.
Radiotherapy has been confirmed as an important treatment breast-conserving surgery reducing the risk of any recurrence of breast cancer and breast cancer-related mortality in patients with early breast cancer. There are no comparative data on the ideal radiotherapy treatment regimen for patients with early stage breast cancer who underwent conservative surgery in the Brazilian population.
