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 verify the effects of resistance training on neuromuscular, vascular and functional adaptations of elderly diabetics type 2. Half of participants will be the intervention group that will perform resistance training, while the other half will be the control group that will perform stretching sessions.
The literature is rich in studies that explore the type and frequency of oral abnormalities in transplanted recipients, but it is scarce in studies that provide scientific evidence on the risk of complications after invasive interventions on those patients. Within this context, the aim of our study is to evaluate the post-exodontic socket healing in renal transplant recipients compared to a control group and see if some indicators in the population of transplanted people, such complete blood count, serum concentration of immunosuppressive drugs, can help to provide for the host response face a invasive procedures. Therefore, 45 kidney transplant recipients over six months and at least 45 healthy non immunosuppressed adults will be submitted to a maximum of 4 simple dental extractions, always by the same surgeon. Laboratory tests will be performed preoperatively and include: blood count and coagulation - for both groups - and urea, creatinine and serum levels of immunosuppressive drug - only for the study group. Researchers will evaluate the patient in the postoperative 3, 7, 21, and 60 days. The presence, or absence, of post-operative complication and delayed, or not, socket healing will be the results of interest in this study and will be compared between the groups. The data will be evaluated by Pearson's chi-square, Fisher's exact test, Mann-Whitney test, student's T-test and binomial test.
Background: Low back pain is a major public health problem that affects most people at some point in life, and results in major psychosocial, economic, functional and physical consequences that can last for days and months. Most cases are undiagnosed and become chronic non-specific low back pain. Studies showed that these patients presented changes in postural control, yet the information is inconsistent, as well as the effects of Functional Taping (FT). Objectives: The aim of this study will be to investigate the immediate and one-month follow-up effects of the use of Functional Taping to lumbar spine on pain intensity and postural control in patients with chronic nonspecific low back pain (CLBP). Methods: This study will be a sham-controlled and randomized clinical trial. Participants: One hundred and twenty participants (18 and 50 years) both genders. Interventions: Participants will be randomly allocated to receive three possible interventions: Functional Star-shape Taping, Sham Functional Taping (both interventions during seven days) and a Minimal Intervention (MI) (one session). Main outcome measures: Primary outcomes will be pain intensity and posturography to assess balance parameters. Low back pain related disability, global perceived effect of treatment and fear avoidance beliefs will be considered as secondary outcomes. Four measurements of static posturography will be conducted: pre-intervention, immediately after application of the tape, after seven days post-intervention (after removal of the tape) and after one month follow-up period. Secondary and primary outcomes will be assessed on three occasions: pre-intervention, seven days post-intervention and after one month follow-up period. All statistical analysis will be conducted following the principles of intention to treat, and the effects of treatment will be calculated using linear mixed models.
Chronic kidney disease (CKD) is linked to elevated mortality rate, and cardiovascular disease is the main cause related to this outcome. The cardiovascular mortality among patients on conventional hemodialysis (CHD) is high, achieving up to 30 times more risk of death when comparing to individuals of same age on general population. Congestive heart failure can develop in 25% to 50% of patients, leading to a worse prognosis. CKD patients present anatomic and functional abnormalities on peripheral bed vases and also cardiovascular abnormalities that can cause myocardial ischemia. This last usually is transitory and lead to left ventricular dysfunction that can persist even after the end of dialysis session despite normal coronary perfusion. The prolonged dysfunction is called myocardial stunning (MS). Patients on CHD are subject to hemodynamic instability, myocardial ischemia and development of regional abnormalities of myocardial wall (ARPM´s). MS induced by intradialytic ischemia is a complication that can be minimized by applying techniques associated to more stability during the CHD, as cool dialysate or increasing the length of the therapy. The goal of the present study is to evaluate the behavior of cardiovascular system (trough hemodynamic performance during CHD, accessing MS by echocardiography technique, and biomarkers associated to MS). Finally, the investigators aimed to investigate the role of two different dialysate calcium concentration (2,5 and 3,5 mEq/l) in the genesis of MS during CHD. The elucidation of pathogenesis of MS during CHD might help us modified hemodialysis technique in order to prevent MS, and reduce the high cardiovascular mortality among CKD patients.
The purpose of this study was to evaluate whether oral finerenone (study drug), in addition to standard daily therapy, is effective and safe in treating patients with type 2 diabetes mellitus and diabetic kidney disease, when compared to a placebo.
The main objective of this study is to evaluate the effect of treatment periodontal endothelium-dependent artery of the arm in patients with acute myocardial infarction with ST-segment elevation undergoing primary coronary intervention.
The purpose of this study is to describe SpyGlass choledochoscopy in patients with post orthotopic liver transplant (OLT) biliary strictures prior to endoscopic therapy and ductal changes after treatment stents.
Comparison of the effects of physical activity (treadmill running) plus thoracic mobilization, physical activity only or a placebo intervention (only manual contact thoracic mobilization), on heart rate variability and pressure pain threshold.
This is a randomized, open-label, multi-center, global, Phase III study to determine the efficacy and safety of durvalumab + tremelimumab combination therapy versus platinum-based SoC chemotherapy in the first-line treatment of patients with epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) wild-type advanced or metastatic NSCLC.
Human immunodeficiency virus (HIV) infection is a major global health issue with up to 40 million people infected worldwide. Due to highly active antiretroviral therapy, mortality related to acquired immunodeficiency syndrome (AIDS) has been reducing in the last decades. However, liver disease remains as an important cause of severe complications and death. Hepatic fibrosis progression is the main responsible for liver-related outcomes in HIV-positive patients. Co-infection by hepatitis B (HBV) or hepatitis C virus (HCV) is highly prevalence in HIV patients. Chronic viral co-infection induces faster liver fibrosis progression compared to mono-infected HIV. However, published data have been reporting presence of significant liver fibrosis in HIV without HBV or HCV infection. This might be related to direct action of HIV in hepatocytes or association with others factors, such as non-alcoholic fatty liver disease (NAFLD). NAFLD is associated with metabolic factors, such as obesity and type-2 diabetes mellitus. However, antiretroviral drugs may induce abnormal body fat distribution (lipodistrophy) and insulin resistance playing an important role on this process. Liver biopsy has been historically considered as the gold standard to evaluate liver injury. However, this painful method presents several limitations. Therefore, several non-invasive methods for estimation of liver fibrosis, such as biomarkers (APRI, FIB-4, FibroTest and FibroMeter) and transient elastography by Fibroscan, have been developed as an alternative to liver biopsy. The diagnostic performance and prognostic value of biomarkers and transient elastography have been validated in patients with chronic liver diseases. However, few data are available in HIV patients, especially in those without chronic viral co-infection. Therefore, patients, medical doctors and scientific community will be beneficiated by the future application of non-invasive methods for estimation of liver injury in clinical practice in HIV patients.
