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.
Epidemiological studies have shown an inverse association between coffee consumption and risk of type 2 diabetes mellitus (T2DM). However the experimental studies that analysed the mechanisms are limited. This project aims to assess the effects of coffee consumption on glucose metabolism, using stable isotope tracer (13C-glucose) to explain the possible metabolic mechanisms involved on the reduced risk for T2DM.
The purpose of this study is to demonstrate that primary prevention patients with one or more additional risk factors (1.5 prevention criteria: syncope/pre-syncope, non-sustained ventricular tachycardia (NSVT), frequent pre-ventricular contractions (PVCs), and low left ventricular ejection fraction (LVEF)) are at a similar risk of life-threatening ventricular arrhythmias (LTVA) when compared to secondary prevention patients, and would receive similar benefit from an implantable cardioverter defibrillator (ICD), or cardiac resynchronization therapy- defibrillator (CRT-D) implant.
This study presents the hypothesis that the sensory processing engine improves balance and agility for football athletes.
The purpose of this study is to assess the effect of two protocols of physiotherapeutic exercises in the maintenance and/or increase of the mandibular range of movement in patients suffering from head and neck cancer (HNC) who are undergoing radiotherapy.
Experimental Procedure: The subjects underwent an initial interview in which was filled in a form of anamnesis, in addition to being assessed and reassessed by spirometry, dynamic circumference and manometer. Moreover, responded international physical activity questionnaire (IPAQ - short version) in order to characterize the physical activity level of each participant being classified as inactive, irregularly active, active, and very active. The same examiner performed the assessments and reassessments of individuals after a training program.
This study will assess the long-term safety and efficacy of repeating treatment with MabThera, in combination with methotrexate and steroids, in patients who were previously randomized into studies WA16291 or WA17043. The anticipated time on study treatment is until Mabthera is available on the local market and the target sample size is 100-500 individuals.
This post-marketing study is designed to compare the safety of tofacitinib versus TNF inhibitor with respect to major cardiovascular adverse events and malignancies, excluding non-melanoma skin cancers when given to subjects with rheumatoid arthritis. Other safety events, including non-melanoma skin cancers, hepatic events, infections, and efficacy parameters will be collected and evaluated in the study.
Background: Hypothermia is common during general and regional anesthesia even when active warming measures are taken. The existing literature shows that, in pregnant patients, the use of forced air-warming during cesarean section under spinal anesthesia does not prevent maternal hypothermia. Therefore, this study aimed to establish the efficacy of a pre-warming system, initiated 30 minutes before the onset of spinal anesthesia and during surgery, in pregnant women subjected to elective cesarean delivery. Methods: Forty healthy pregnant patients undergoing elective cesarean section with spinal anesthesia were allocated to the control group (Gcont, n = 20), without the use of a thermal gown, and to the gown group (Ggown, n = 20), with the use of a thermal gown in the preoperative care unit, 30 minutes before spinal anesthesia installation and during surgery. After the anesthesia, the thermal gown was moved from the regular position and placed over the chest and upper limbs, as an upper body blanket, and maintained throughout the study. The following variables were observed: preoperative and operative room temperature, hemoglobin saturation, heart rate, arterial pressure, tympanic temperature in the preoperative care unit room (baseline) and at 0, 15, 30, 45 and 60 minutes after spinal anesthesia. Repeated Measure ANCOVA compared temperatures of each group, adjusted for baseline values.
In this study, eligible alcoholic inpatients recruited from a specialized clinic for addiction treatment, filling inclusion criteria and not showing any exclusion criteria, were randomized to receive the repetitive (10 sessions, every other day) bilateral dorsolateral Prefrontal Cortex (dlPFC: cathodal left / anodal right) tDCS (2 milliamperes, 5 x 7 cm2, for 20 min) or placebo (sham-tDCS). Craving to the use of alcohol was examined before (baseline), during and after the end of the tDCS treatment. Based in our previous data, our hypothesis was that repetitive bilateral tDCS over dlPFC would favorably change craving in alcoholism and this would be a long-lasting effect.
In this study, eligible crack-cocaine addicted inpatients recruited from specialized clinics for substance abuse disorder treatment, filling inclusion criteria and not showing any exclusion criteria, were randomized to receive the repetitive (10 sessions, every other day) bilateral dorsolateral Prefrontal Cortex (dlPFC: cathodal left / anodal right) tDCS (2 milliamperes, 3x7 cm2, for 20 min) or placebo (sham-tDCS). Craving to the use of crack-cocaine was examined before (baseline), during and after the end of the tDCS treatment. Based in our previous data, our hypothesis was that repetitive bilateral tDCS over dlPFC would favorably change clinical, cognitive and brain function in crack-cocaine addiction and these would be long-lasting effects.
