Nas secções seguintes é apresentado todo o processo de desenvolvimento do IRIS (Índice de Risco de Suicídio) - um novo índice com o mesmo objectivo de avaliação mas construído utilizando metodologias que proporcionam avanços qualitativos em relação aos índices existentes, bem como uma melhor adequação a contingências e características da realidade portuguesa. The introduction contains a historical and conceptual review of psychometric tools that aim at assessing the risk of suicide in individuals presenting suicidal ideation. In the following sections the whole process of development of IRIS (“Índice de Risco de Suicídio” – Suicide Risk Index) is presented - a new tool with the same objective but built using methods that provide qualitative advances over existing indexes, while better accounting for the contingencies and characteristics of the Portuguese reality

Avaliação da resistência de genótipos de milho, sorgo e milheto a Meloidogyne javanica e M. incognita raca 3.

O uso de espécies cultivadas resistentes aos nematóides formadores de galhas, em sistemas de rotação de culturas, mantém a população dos nematóides em níveis baixos, diminuindo as perdas e possibilitando o plantio de espécies mais susceptíveis. No presente trabalho avaliou-se a resistência de genótipos de milho, sorgo e milheto aos nematóides de galhas Meloidogyne javanica e M. incognita raça 3. Os ensaios foram conduzidos em casa de vegetação e os genótipos semeados em vasos plásticos contendo 2 litros de substrato esterilizado (três partes de areia e uma de solo), e inoculados com 5.000 ovos de nematóide por vaso, dispostos em delineamento inteiramente casualizado com oito repetições. Plantas de tomateiro foram utilizadas para confirmar a viabilidade do inóculo. A avaliação da reprodução dos nematóides foi feita 60 dias após a inoculação, através da contagem do número de ovos por sistema radicular das plantas de cada genótipo, calculando-se o Fator de Reprodução (FR=Pf/Pi, sendo Pf a população final de ovos e larvas de nematóide e Pi a população inicial). De acordo com os resultados, todos os genótipos de milho, sorgo e milheto comportaram-se como resistentes à reprodução de M. javanica; quanto à M. incognita raça 3, mostraram maior nível de resistência os genótipos de milho, CMS 100 02 2, HS 723x724, 97 HT 14 A, BRS 3123, BRS 2114, CMS 14 B, CMS 2000 17 A, CMS 99 14 C, 52 HT03-QPM, HS 111764040, e todos os genótipos de sorgo e de milheto. Os genótipos resistentes comerciais são indicados para uso em rotação em áreas infestadas por esses nematóides

Perceptions of portuguese family health care teams regarding the expansion of nurses’ scope of practice = Perceções de equipas de saúde familiar portuguesas sobre o alargamento do campo de exercício da enfermagem

Theoretical framework: Expanding primary health care nurses’ scope of practice is a strategy that has been used in various health systems to good advantage. Its feasibility depends on the health professionals’ consensus as to its suitability. Objectives: To find out the perceptions of Portuguese family health care teams regarding the expansion of primary care nurses’ scope of practice. Methodology: Focus groups. Results: The team perception is that citizen expectations, the shortage of nurses and the need for specific training are the main issues to be faced. The teams discussed various roles that the nursing profession could take on in Primary Health Care (PHC) via a work reorganisation included in the regulatory framework. Conclusion: The assignment of wider clinical roles to PHC nurses is not unanimously approved of, since it is perceived by some doctors and nurses as inappropriate and unfair. Some health care teams expressed their willingness to take part in this option, due to its potential contribution to improving the response to care needs not currently being met. Enquadramento: O alargamento do campo de exercício do enfermeiro de cuidados primários tem constituído uma estratégia utilizada em diversos sistemas de saúde com ganhos conhecidos. A sua exequibilidade depende do consenso dos profissionais de saúde sobre a sua adequação. Objetivos: Conhecer as perceções de equipas de saúde familiar portuguesas sobre o alargamento do campo de exercício do enfermeiro de cuidados primários. Metodologia: Grupos focais. Resultados: Na perceção das equipas, as expetativas dos cidadãos, a escassez de enfermeiros e a necessidade de formação específica são os principais problemas a enfrentar. As equipas discutiram vários papéis que a profissão de enfermagem poderia assumir em Cuidados de Saúde Primários (CSP), mediante uma reorganização do trabalho, enquadrada normativamente. Conclusão: A atribuição de papéis clínicos mais vastos ao enfermeiro de CSP não reúne unanimidade, por ser percebida, por alguns médicos e enfermeiros, como desajustada e iníqua. Algumas equipas de saúde manifestaram disponibilidade para aderir a esta opção, face ao seu potencial contributo para melhorar a resposta a necessidades assistenciais atualmente não satisfeitas.publishersversionpublishe

Contact Detection Algorithm for Convex NURBS Particles

The present work proposes a contact detection algorithm for convex particles whose boundaries are mathematically defined by non-uniform B-splines (NURBS). This algorithm involves a hierarchy of contact searches, including both global and local steps. The focus is on the formulation of the local contact problem (LCP) using a master-to-master approach. It is based on computer graphics and optimization techniques. Besides the algorithm, the paper also discusses strategies for modeling particle geometry and their implications in contact detection. The use of multiple parameterizations (patches) assembled in space, for instance, provides more flexibility in the construction of particles and avoids numerical singularities. However, it leads to local geometric imperfections at the connection between patches. The LCP formulation proposed herein can deal with such imperfections through a contact degeneration technique. An example shows the robustness of the method

Supercritical CO2 assisted impregnation of ibuprofen on medium-chain-length polyhydroxyalkanoates (mcl-PHA)

This work is financed by national funds from FCT-Fundacao para a Ciencia e a Tecnologia, I.P., in the scope of the project UIDB/50006/2020 of the Associate Laboratory for Green Chemistry-LAQV, the project UIDP/04378/2020 and UIDB/04378/2020 of the Research Unit on Applied Molecular Biosciences-UCIBIO and the project LA/P/0140/2020 of the Associate Laboratory Institute for Health and Bioeconomy-i4HB. Liane Meneses and Alexandre Paiva would like to acknowledge FCT for the financial support through SFRH/BD/148510/2019 and IF/01146/2015.In this work, we propose the utilization of scCO2 to impregnate ibuprofen into the mcl- PHA matrix produced by Pseudomonas chlororaphis subs. aurantiaca (DSM 19603). The biopolymer has adhesive properties, is biocompatible and has a melting temperature of 45 °C. Several conditions, namely, pressure (15 and 20 MPa) and impregnation time (30 min, 1 h and 3 h) were tested. The highest ibuprofen content (90.8 ± 6.5 mg of ibuprofen/gPHA) was obtained at 20 MPa and 40 °C, for 1 h, with an impregnation rate of 89 mg/(g.h). The processed mcl-PHA samples suffered a plasticization, as shown by the decrease of 6.5 °C in the Tg, at 20 MPa. The polymer’s crystallinity was also affected concomitantly with the matrices’ ibuprofen content. For all the impregnation conditions tested the release of ibuprofen from the biopolymer followed a type II release profile. This study has demonstrated that the mcl-PHA produced by P. chlororaphis has a great potential for the development of novel topical drug delivery systems.publishersversionpublishe

a fundamental step to qualify searches and expand studies in the health area

Publisher Copyright: © 2024, Institute de Medicina Social da UERJ. All rights reserved.This article aims to contribute to ref lection on using and appropriating the term “meta-evaluation” in health research, especially regarding the importance of adopting the controlled vocabulary. It is assumed that the DeCS/MeSH thesaurus is widely used for indexing and retrieving scientific articles in health research. However, the term “meta-evaluation” does not appear as a controlled descriptor option in this database. The text is presented in the form of a theoretical essay, discussing the relevance of evaluative practices and the need to expand and consolidate studies on meta-evaluation in the health area. Including the term "meta-evaluation" in the DeCS/MeSH database is fundamental and proposed.publishersversionpublishe

Deep eutectic systems for carbonic anhydrase extraction from microalgae biomass to improve carbon dioxide solubilization

This work was supported by the project “DESalgae – Capturing and re-using CO2 using deep eutectic solvents and microalgae” funded by Dutch national fund NWO Open Competition Domain Science – XS [ OCENW.XS4.162 ]; Special thanks to AlGreen B.V. (Wageningen) for providing Spirulina sp. biomass. Publisher Copyright: © 2022 The Authors.This work is the first proof-of-concept of the use of carbonic anhydrase (CA) enzyme from microalgae biomass, extracted with deep eutectic systems (DES), with the goal of engineering a solution that will lead to a breakthrough in the Carbon Capture and Utilization (CCU) strategy. Three distinct microalgae were processed-Tisochrysis lutea, Chlorella vulgaris, and Spirulina sp.-with three DES-Choline chloride-Urea (ChCl-U), Choline chloride-Poly(ethylene glycol) (ChCl-PEG), and Poly(ethylene glycol)-Urea (PEG-U). To evaluate the most promising microalgae-DES, CA activity was evaluated with a specific enzymatic activity kit and through CO2 solubility assays. Preliminary results indicate that: DES is a suitable solvent medium for CA extraction from microalgal biomass, preserving its activity (specific CA activity up to 0.70 mU.mg-1); CA extraction efficiency differs between DES and microalgal species, indicating the potential for further research; from the tested DES, the ones containing PEG were favorable to maintain CA activity (CO2 solubility up to 4 g CO2.g-1 DES). This work paves the way towards a disruptive CCU approach.publishersversionpublishe

Design of cold-formed steel battened built-up columns

When individual profiles cannot withstand the acting forces, cold-formed steel (CFS) battened built-up columns may be used to provide a suitable load-bearing capacity. A suitable load-bearing capacity can be achieved when the individual profiles present a high composite action. The ideal configuration for battened CFS columns to enable composite action between two lipped-channels CFS profiles is shown in this research. Various column lengths and different spacing between lipped channels were considered. A calibrated finite element modeling approach evaluated the influence of the number of fasteners per batten panel and the distance between the batten panels. Furthermore, the appropriate number of fasteners per batten panel was discussed. After identifying the optimal details for the battened column, a parametric study was done. The maximum axial loads of a series of finite element models were compared to analytical predictions from different design methodologies according to EN1993-1-1 and AISI S100. The results recommended the use of three rows of fasteners per batten panel. Furthermore, a new analytical procedure was proposed by adopting the modified slenderness ratio in AISI S100-16 in the formulation provided in EN1993-1-1. The reliability of the available methodologies was assessed by comparing the reliability index for the analytical methods.This work is financed by national funds throughthe Portuguese Foundation for Science and Technology (FCT) under grant agreement 2021.06528.BD attributed to the 1st author and under the grant agreement 2020.03588.
