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 purpose of this study is to evaluate the effectiveness of pharmaceutical care, compared to usual care, in improving medication adherence behaviour of ambulatory hemodialysis patients.
Urinary incontinence is defined according to the International Continence Society as any involuntary loss of urine, which may bring several negative consequences on women's lives, and among incontinent women, about 50% have urinary incontinence, 30% mixed and 20% emergency. The overactive bladder present in urge incontinence and mixed cause significant impacts on people's lives and has a prevalence of 16.5% in the US population. Behavioral therapies, exercises the pelvic muscles and drugs are the main forms of treatment. Drug therapy using drugs which are not specific for the bladder and are associated with many unwanted systemic side effects. The results obtained by researchers in several countries using conservative techniques in the treatment of patients with urinary incontinence are encouraging and this study aims to evaluate carefully and systematically the effectiveness of tibial stimulation technique. Importantly, also, that conservative techniques have lower cost than the surgical treatment and have virtually no side effects as most of the drugs used in the pharmacological treatment of female urinary incontinence.
The main purpose of this study is to evaluate the efficacy of the combination of doxorubicin plus the study drug known as olaratumab versus doxorubicin plus placebo in participants with advanced or metastatic soft tissue sarcoma.
Chronic kidney disease (CKD) is one of the most common microvascular complications of diabetes mellitus, and it is the leading cause of end stage renal disease on developed countries. The CKD diagnosis and its progression require re-evaluation of hypoglycemic therapy and constant dosing adjustments, in order to optimize glycemic control and minimize its side effects. Long acting insulin analogs and its pharmacokinetics have not been studied through different stages of kidney disease and there is no consensus defining the appropriate dosing adjustment based on the glomerular filtration rate (GFR). This research project will compare the glycemic response to intensive insulin treatment with NPH insulin and basal insulin analog (insulin glargine) in type 2 diabetes (DM 2) patients with CKD stages 3 and 4. Patients and methods - Inclusion Criteria: DM 2 patients with CKD secondary to diabetic nephropathy and GFR of 15-59 ml/min/1.73m². Exclusion Criteria: Patients with systemic neoplasia, HIV, CKD or nephropathy from other etiologies, severe psychiatric disorders and pregnant women. Study design: This study consists of a randomized, cross-over, open-label controlled clinical trial. Patients will be randomly divided into two groups: GROUP 1 - insulin analog glargine once a day and GROUP 2 - NPH human insulin, three applications per day, both group will be treated with insulin lispro at mealtime. The laboratory tests will be performed at baseline and 12, 24, 36 and 48 weeks after the study start. During routine medical appointments will be analyzed self- monitoring of capillary blood glucose (SMBG) and the hypoglycemia score. After 24 weeks the basal insulin will be changed, i.e. patients using NPH insulin will receive insulin glargine and patients on insulin glargine will be changed to NPH insulin. A CGMS will be carried out at 24 and 48 weeks. Methodology: The metabolic profile will be evaluated throughout SMBG; biochemical, hormonal and hematological measurements; hypoglycemia score and CGMS. Statistical analysis will be performed using comparative descriptive analyzes, such as chi-square distribution, t-test and non-parametric tests. Analyze of data CGMS will include the area under the curve and the related statistic. Finally, logistic regression models will be adopted to evaluate the effect of the treatment on the several variables in question.
Recent evidences from small studies show potential benefit of acupuncture in the treatment of obstructive sleep apnea (OSA). These studies did not evaluate the benefit of the treatment on the cardiovascular system. Primary end-point: To investigate the effects of acupuncture in improving OSA severity among hypertensive patients. Secondary end-point To investigate the effect of acupuncture in improving the quality of life and sleep assessed by the Short Form 36 (SF-36) questionnaire and Pittsburgh Questionaire (PSQI); To investigate the effect of acupuncture in blood pressure and arterial stiffness
This trial is investigating the efficacy and safety of highly purified human chorionic gonadotropin (HP-hCG) and recombinant human chorionic gonadotropin (rhCG) for triggering of final follicular maturation in women undergoing controlled ovarian stimulation
This is a pilot study evaluating the effect of a simplified low-cost (friendly) controlled ovarian stimulation using clomiphene citrate, letrozole, and Corifollitropin Alfa on the number of oocytes retrieved.
BACKGROUND: The physiopathology of the heart failure involves compensatory mechanisms as exacerbated neurohormonal activity, endothelial dysfunction and consequently the muscle disability and exercise intolerance. The interval exercise training has been proposed as one efficient method to heart failure patients. It seems that the main mechanism involved in the benefit of the interval exercise training is "shear stress". AIM: To study the interval exercise training versus the continuous exercise training in the sympathetic activity and in the peripheral muscle perfusion in heart failure patients. Moreover, we will evaluate the muscle apoptosis, microRNA in plasma and muscle biopsy, biomarkers levels of inflammation, quality of life and exercise capacity. METODOLOGY: Will be selected 40 patients (male and female) with age between 30 and 60 years, left ventricular ejection fraction less than 40% and functional class I, II and III. These patients will be randomized into three groups: Interval (AIT), continuous (MCT) and control (CG). All patients will be evaluated with microneurography, peripheral muscle perfusion, muscle biopsy, blood samples, accelerometer, cardiopulmonary exercise test and quality of life before and after end of the period of 03 (three) months.
Cardiovascular exercise adjustments are required during in order to redistribute blood flow from non-exercising vascular areas to active muscles. This hemodynamic adjustments, which are partially mediated by mechanosensitive and metabosensitive reflexes, ultimately increase oxygen and nutrient delivery to exercising muscle tissues (Mitchell, 1990). Static handgrip exercise has been shown to induce alterations in the arterial baroreflex function (Kim, 2005) and activation of muscle metaboreflex that increases arterial blood pressure and peripheral vasoconstriction, respectively. Functional electrical stimulation (FES) treatment used in physical therapy in patients who are unable to tolerate conventional exercise showed to be a good alternative for muscle strengthening (Sbruzzi, 2010) and to improve metabolic abnormalities (Karavidas, 2006). However, the effect of FES on metaboreflex activation in healthy individuals has never been investigated. Therefore, this study aims to evaluate the metaboreflex activation induced by FES in upper and low limbs in healthy individuals, and also to compare their results with the effects caused by isometric exercise.
