Natriuretic Peptide and Clinical Evaluation in the Diagnosis of Heart Failure Hemodynamic Profile: Comparison with Tissue Doppler Echocardiography

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Physical examination and B-type natriuretic peptide (BNP) have been used to estimate hemodynamics and tailor therapy of acute decompensated heart failure (ADHF) patients. However, correlation between these parameters and left ventricular filling pressures is controversial. Objectiv...

Exercise Training Attenuates Sympathetic Activity and Improves Morphometry of Splenic Arterioles in Spontaneously Hipertensive Rats

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Alterations in the structure of resistance vessels contribute to elevated systemic vascular resistance in hypertension and are linked to sympathetic hyperactivity and related lesions in target organs. Objective: To assess the effects of exercise training on hemodynamic and autonomi...

Migraine improvement correlates with posterior cingulate cortical thickness reduction

Arq. neuropsiquiatr; 76 (3), 2018
ABSTRACT Objective The main goal of this study was to correlate migraine improvement, after prophylactic therapy, with cortical thickness changes. Methods Cortical thickness maps were obtained with magnetic resonance imaging (MRI) from 19 patients with migraine before (first scan) and after (second sca...

Is phrenic nerve conduction affected in patients with difficult-to-treat asthma?

Arq. neuropsiquiatr; 76 (3), 2018
ABSTRACT Objective The aim of this study was to obtain data on phrenic neuroconduction and electromyography of the diaphragm muscle in difficult-to-treat asthmatic patients and compare the results to those obtained in controls. Methods The study consisted of 20 difficult-to-treat asthmatic patients com...

Normative values of the Brief Repeatable Battery of Neuropsychological Tests in a Brazilian population sample: discrete and regression-based norms

Arq. neuropsiquiatr; 76 (3), 2018
ABSTRACT Objective Cognitive dysfunction is common in multiple sclerosis. The Brief Repeatable Battery of Neuropsychological Tests (BRB-N) was developed to assess cognitive functions most-frequently impaired in multiple sclerosis. However, normative values are lacking in Brazil. Therefore, we aimed to p...

Current contribution of diffusion tensor imaging in the evaluation of diffuse axonal injury

Arq. neuropsiquiatr; 76 (3), 2018
ABSTRACT Traumatic brain injury (TBI) is the number one cause of death and morbidity among young adults. Moreover, survivors are frequently left with functional disabilities during the most productive years of their lives. One main aspect of TBI pathology is diffuse axonal injury, which is increasingly r...

The importance of central auditory evaluation in Friedreich's ataxia

Arq. neuropsiquiatr; 76 (3), 2018
ABSTRACT Objective To assess central auditory function in Friedreich's ataxia. Methods A cross-sectional, retrospective study was carried out. Thirty patients underwent the anamnesis, otorhinolaryngology examination, pure tone audiometry, acoustic immittance measures and brainstem auditory evoked poten...

Ash content, carbon and C/N ratio in paricá in function of NPK fertilization

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Fertilization in areas of forest plantations is needed to supplement plants´ nutritional needs until harvest. An experiment was performed to check the influence of fertilization on levels of ash, carbon and C/N relation in Schizolobium amazonicum. Soil liming was performed and fertilization occ...

Population dynamics of Aphis gossypii Glover and in sole and intercropping systems of cotton and cowpea

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Population dynamics of aphids have been studied in sole and intercropping systems. These studies have required the use of more precise analytical tools in order to better understand patterns in quantitative data. Mathematical models are among the most important tools to explain the dynamics of i...
