Brazilian practice guidelines for stroke rehabilitation: Part II

The Brazilian Practice Guidelines for Stroke Rehabilitation – Part II, developed by the Scientific Department of Neurological Rehabilitation of the Brazilian Academy of Neurology (Academia Brasileira de Neurologia, in Portuguese), focuses on specific rehabilitation techniques to aid recovery from impairment and disability after stroke. As in Part I, Part II is also based on recently available evidence from randomized controlled trials, systematic reviews, meta-analyses, and other guidelines. Part II covers disorders of communication, dysphagia, postural control and balance, ataxias, spasticity, upper limb rehabilitation, gait, cognition, unilateral spatial neglect, sensory impairments, home rehabilitation, medication adherence, palliative care, cerebrovascular events related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the future of stroke rehabilitation, and stroke websites to support patients and caregivers. Our goal is to provide health professionals with more recent knowledge and recommendations for better rehabilitation care after stroke

Effects of Zr content on microstructure and corrosion resistance of Ti-30Nb-Zr casting alloys for biomedical applications

Titanium alloys show attractive properties for biomedical applications where the most important factors are biocompatibility, corrosion resistance, low modulus of elasticity, very good strength-to-weight ratio, reasonable formability and osseointegration. The aim of this study was to investigate the effects of Zr content (7.5 and 15 wt%) on microstructure and corrosion resistance of Ti-30Nb-Zr as-cast alloy samples. The corrosion tests were carried out in a 0.9% NaCl (0.15 mol L-1) solution at 25 degrees C and neutral pH range. A horizontal centrifuged solidification set-up was used to obtain as-cast samples with a fine dendritic arrangement. In order to evaluate the corrosion behavior, electrochemical impedance spectroscopy (EIS), polarization curves and an equivalent circuit analysis were used. It was found that the as-cast microstructure tends to have the dendrite arm spacings reduced with increasing Zr content. The results have shown that the addition of Zr to a Ti-30Nb alloy has been efficient to stabilize the beta phase. The resulting impedance parameters and passive current densities have shown that the Ti-30Nb alloys sample without Zr addition presents a higher surface reactivity which can induce a better osseointegration than those containing Zr.

Solute segregation and its influence on the microstructure and electrochemical behavior of Ti-Nb-Zr alloys

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)The main aim of this work is to evaluate microstructure and electrochemical behavior of Ti-30Nb-xZr alloys using polarization techniques. Several alloys with different Zr contents were evaluated (from 2.5 to 15 wt.%). Samples were prepared by arc melting and cast in copper molds in a centrifugal casting machine. The as-cast samples showed a dendritic microstructure whose scale was found to depend on the Zr content. Martensite formation proved to be dependent on solute segregation. It was observed that the addition of Zr has no influence on corrosion potential. However, Zr addition affects the passive current density behavior. After polarization, the microstructures with passive film formed on their surfaces were analyzed by scanning electron microscopy. (C) 2008 Elsevier B.V.

From therapy to daily life of a depressed adolescent: Crossing psychopathology and optimal functioning

First published online: 30 November 2017Recently, scientific literature has seen significant development and evaluation of several positive psychology interventions. However, there are still lacking studies that evaluate the efficacy of this type of interventions in clinically depressed adolescents. This paper aims to demonstrate the preliminary results of a new therapy implemented to a 14-year-old female adolescent diagnosed with Major Depressive Disorder: the Optimal Functioning Therapy for Adolescent. This therapy seeks to promote adolescents’ optimal functioning by reducing depressive symptoms and increasing well-being. The innovation of this therapy lies in the integration of techniques from Cognitive-Behavioral Therapy and Positive Psychology Interventions. The assessment of this therapy was made using retrospective and real-time or ecological measures (Experience Sampling Method – Csikszentmihalyi and Larson in Journal of Nervous and Mental Disease, 175, 526–536, 1987) in three moments: baseline; post-intervention; and 4-month follow-up. Retrospective results showed improvement in positive trait characteristics and elimination of depressive symptoms maintained until follow-up. Real-time results showed the benefits of the therapy on the participant’s daily life regarding external contexts (increased engagement and diversification of activities, places, and companies) and state characteristics (increase in positive mood and self-satisfaction, and a decrease in the negative mood), maintained until follow-up. The Optimal Functioning Therapy for Adolescents contributed to the treatment of Major Depressive Disorder and optimal functioning enhancement.(undefined)info:eu-repo/semantics/publishedVersio
