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.
Recent studies have shown that chronic stimulation of the right ventricle can cause deleterious effects to cardiac function and synchronicity. The occurrence and consequences of this phenomenon in children and young patients with cardiac pacemaker due to advanced atrioventricular block (AVB) are still unknown. Thus, our aims is to assess the chronic effects of cardiac pacing in children and young patients with advanced AVB and its impact on clinical, functional and echocardiographic parameters.
The cardiac abnormalities in patients with cirrhosis are already reported from the 50's, in studies of patients with alcoholic cirrhosis. Further studies have shown that these cardiac changes were caused not only by the myotoxic effects of alcohol, but also are present in many patients regardless of etiology of cirrhosis. These changes are characterized by abnormalities of systolic contraction in patients undergoing physical or pharmacological stress, changes in diastolic function and electrophysiological changes in a clinical condition known as cirrhotic cardiomyopathy. Increased QT interval and the pre-ejection time changes are common in cirrhotic patients. To date no studies have evaluated the clinical relevance of changes in the heart of cirrhotic patients, or their relationship with the prognosis of affected patients. Til now, researches are based on strict echocardiographic parameters, not including several modern methods of assessment of cardiac systole and diastole. New techniques, such as two-dimensional strain, can bring new diagnostic and prognostic information, and it is not reported in the literature. Therefore, the aim of this study is to determine the morphological and functional cardiac changes in patients with cirrhosis and their prognostic role by evaluating new echocardiographic parameters of systolic and diastolic readings.
The purpose of this study is to compare the vaginal sacrospinous colpopexy and high uterosacral colpopexy in the treatment of genital prolapse grade III/IV in women with uterus.
Many authors link tinnitus to arterial hypertension. The aim of this study is to establish a possible relationship between them, analyze the severity of tinnitus related to arterial hypertension and analyze a possible influence of ototoxic drugs used to treat arterial hypertension
The Observational Study in the "Real World" of Implantable Electronic Cardiac Devices will enable the construction of an electronic database with local access to clinical information, which will collect and disseminate epidemiologic data on demography, cardiovascular mortality and morbidity, and potential risk factors for a selected group of patients. These clinical variables will be analyzed against the data, as based in the programming of devices and the diagnostics. Approved descriptive statistics and analyses will be made available via Internet. The study will describe statistical indexes on sub-groups representing more than 10% of total of datasets. The study will be open to include any patient that had a Medtronic electronic device implanted, pacemakers, ICD, ICD with CRP. The study will be also adapted for devices implanted in the present and for devices to be implanted in patients in the future.
Set of real acupuncture treatment and supervised aerobic exercise have better efficacy in pediatric patients with fibromyalgia versus treatment with sham acupuncture and supervised aerobic exercise, as well as treatment versus combination with aerobic exercise and resistance exercise the major muscle groups, both supervised versus group control, who just get guidance for physical activity.
Introduction: Chronic kidney disease (CKD) is now an important public health issue. While 0.1% of the population is on dialysis, approximately 4.5% of subjects have renal dysfunction (glomerular filtration rate <60 ml/min/1.73 m2). These patients have a high mortality of cardiovascular disease (CVD) with low quality of life and survival, despite high expenditure on their treatment. Hypertension (SAH) is both a cause and a complication of CKD. In addition, CKD and hypertension are risk factors for CVD. The nephropathy that are not on dialysis are less studied than those on dialysis. Strategies are needed to maintain renal function in these patients and mitigate the risk factors for CVD. A sedentary lifestyle can be an important determinant of morbidity of mortality. This study aims to determine the effect of exercise in patients with CKD not yet on dialysis. Methodology: A randomized clinical trial in hypertensive patients with CRF. After recruitment of participants and completed baseline surveys, those eligible for inclusion and consented to participate in the study will be randomly assigned. We use the technique of randomization in blocks of fixed size of six persons. Variables to be collected: demographic, socioeconomic, behavioral, anthropometric, blood pressure, laboratory tests (anemia, the lipid profile, blood glucose, inflammatory markers and number of peripheral endothelial progenitor cells) and quality of life. These patients will be re-interviewed in the middle period of the study (10 weeks) at the end of the intervention (20 weeks) and 10 weeks after the end of the intervention. The intervention group will participate in two weekly sessions of exercise. Therefore, facing the epidemic of CKD, this study intends to fill the data gaps about the impact of physical activity in patients with CKD on dialysis.
Studying the results of treatment of dilated vessels of the lower limbs with laser, and compare them to those obtained with sclerotherapy.
A Prospective Double-Blinded, Placebo Controlled, Randomized Trial comparing a single dose of Vitamin D (Colecalciferol) 300.00UI to placebo on patients with insulin resistance. Primary Outcome: Blood glucose and homeostasis model assessment for insulin resistance (HOMA-R) after 90 days. Study hypothesis: Vitamin D treatment may improve insulin resistance and decrease glucose level, since there is an association between hypovitaminosis D and increased insulin resistance.
Workers in the various branches of the investigators industrial society can be considered as a group susceptible to risks due to the nature of its activities related to the intense demands of their work units with varying degrees of physical overload. Among the risk factors involved in postural genesis of occupational low back pain is work in uncomfortable positions, such as maintenance of static postures for long periods of time and frequent implementation of flexion, extension and trunk rotation.The association between body instability (lack of postural balance) and back pain is seen with some frequency, especially in working groups.
