Adaptação transcultural do Vulnerable Elders Survey-13 (VES-13): contribuindo para a identificação de idosos vulneráveis

Para a utilização do VES-13 instrumento que identifica idosos vulneráveis foi realizada sua adaptação transcultural, processo que visa à equivalência entre o instrumento original e sua versão em outra cultura. A avaliação da equivalência semântica, idiomática cultural e conceitual obteve uma média geral de concordância de 78%, 78%, 97% e 94%, respectivamente. Para verificar a concordância no teste-reteste, utilizou-se o coeficiente Kappa de Cohen, onde a maioria das variáveis foram significantes. A análise de sua consistência interna foi verificada pelo uso do coeficiente alpha de Cronbach, onde 70% do fenômeno em estudo estão representados no instrumento. O VES-13, traduzido e adaptado, mostrou-se um instrumento confiável no que diz respeito à estabilidade e consistência interna de suas medidas. Sua estrutura simples e de fácil aplicabilidade pode, portanto, favorecer a identificação das pessoas idosas vulneráveis, contribuindo, assim, para a priorização do acompanhamento pelos serviços de saúde.

Vulnerabilidade em pessoas idosas residentes na comunidade : estudo exploratório em utentes da Santa Casa da Misericórdia de Lisboa

RESUMO: Objectivo: O presente estudo tem como principal objectivo a caracterização da vulnerabilidade individual em pessoas idosas residentes na comunidade. Metodologia: Trata-se de um estudo não experimental, exploratório, quantitativo, e transversal numa amostra probabilística de aleatorização simples (n=213). A vulnerabilidade individual foi avaliada com recurso ao instrumento Vulnerable Elders Survey 13 e as restantes variáveis sócio-demográficas por questionário, ambas por via telefónica. Resultados: A amostra era predominantemente feminina, com uma maior prevalência das pessoas com 75 ou mais anos, viúvas, sem escolaridade, maioritariamente a viverem sós e mais de com um rendimento mensal igual ou inferior a 485€. Relativamente à vulnerabilidade, numa amostra aleatorizada de 213 pessoas, apenas 15 não apresentavam vulnerabilidade, avaliada pelo Vulnerable Elders Survey-13 (VES-13). Das 198 pessoas vulneráveis, correspondendo a 93% da amostra, 164, ou seja, 77% deste grupo, tinham uma pontuação total igual ou superior a 7 em 10, revelando um grau elevado de vulnerabilidade. Conclusão: As variáveis preditoras da vulnerabilidade são a idade, quanto maior a idade maior a vulnerabilidade, e o ser-se viúvo. As variáveis preditoras da dificuldade na realização das actividades físicas (AF) são a idade e pessoa isolada em alojamento colectivo. Para as actividades de vida diária (AVD), as variáveis que demostram ser preditoras são a idade, pessoa isolada em alojamento colectivo e residir em agregado familiar de casal de idosos.----------------------- ABSTRACT:Objective: The present study has as its principal objective the characterization of individual vulnerability in community-dwelling older people. Methodology: This is a non-experimental study, exploratory, qualitative, quantitative, and cross-sectional in a probabilistic sample of simple randomization (n=213). Individual vulnerability was assessed using the instrument Vulnerable Elders Survey 13 and the other socio-demographic variables by questionnaire, both by telephone. Results: the sample was predominantly female, with a higher prevalence of persons with 75 or more years, widows, without education, mostly living alone and most of all with less than or equal to 485€ per month. Concerning vulnerability, in a random sample of 213 people, only 15 doesn´t present vulnerability, evaluated by the Vulnerable Elders Survey-13 (VES-13). Of the 198 people vulnerable, accounting for 93% of the sample, 164, i.e. 77% of this group, had a total score equal to or greater than 7 in 10, revealing a high degree of vulnerability. Conclusion: The predictors of vulnerability are the age, where higher the age means greater vulnerability as well as being a widow. The predictors of the difficulty in physical activities are old age and isolated persons in collective accommodation. For the activities of daily life, the variables that demonstrate as being predictors are old age, isolated persons in collective accommodation and living in elderly couple.

Valutazione preoperatoria del rischio chirurgico in pazienti onco-geriatrici (studio PREOP)

La maggior parte dei pazienti che vengono sottoposti a interventi chirurgici per tumori solidi hanno un’età superiore a 70 anni1. Circa il 30% di questi pazienti vengono considerati “fragili”. Questi infatti presentano numerose comorbidità ed hanno un più elevato rischio di sviluppare complicanze postoperatorie con perdita della riserva funzionale residua. Per questo non esistono sistemi semplici di screening che permettano ai medici responsabili del trattamento di identificare questi pazienti con aumentato rischio postoperatorio. Identificare i pazienti a rischio è infatti il primo passo nel processo attraverso il quale è possibile prevenire in necessarie complicanze postoperatorie come delirio, eventi cardiovascolari e perdita della funzionalità complessiva con conseguente perdita di autonomia. Scopo di questo studio è quello di confrontare l’accuratezza nella previsione di mortalità e morbidità a 30 giorni dei tre test preditivi “Groningen Frailty Index” (GFI); “Vulnerable Elders Survey” (VES-13); “timed up and go test” con alcune componenti del Preoperative Assessment of Cancer in the Elderly (PACE). Lo studio verrà effettuato sui pazienti con età maggiore di 70 anni che dovranno essere sottoposti a intervento chirurgico in anestesia generale per la presenza di una neoplasia solida.

Bp-13 Pla2: Purification And Neuromuscular Activity Of A New Asp49 Toxin Isolated From Bothrops Pauloensis Snake Venom.

A new PLA2 (Bp-13) was purified from Bothrops pauloensis snake venom after a single chromatographic step of RP-HPLC on μ-Bondapak C-18. Amino acid analysis showed a high content of hydrophobic and basic amino acids and 14 half-cysteine residues. The N-terminal sequence showed a high degree of homology with basic Asp49 PLA2 myotoxins from other Bothrops venoms. Bp-13 showed allosteric enzymatic behavior and maximal activity at pH 8.1, 36°-45°C. Full Bp-13 PLA2 activity required Ca(2+); its PLA2 activity was inhibited by Mg(2+), Mn(2+), Sr(2+), and Cd(2+) in the presence and absence of 1 mM Ca(2+). In the mouse phrenic nerve-diaphragm (PND) preparation, the time for 50% paralysis was concentration-dependent (P < 0.05). Both the replacement of Ca(2+) by Sr(2+) and temperature lowering (24°C) inhibited the Bp-13 PLA2-induced twitch-tension blockade. Bp-13 PLA2 inhibited the contractile response to direct electrical stimulation in curarized mouse PND preparation corroborating its contracture effect. In biventer cervicis preparations, Bp-13 induced irreversible twitch-tension blockade and the KCl evoked contracture was partially, but significantly, inhibited (P > 0.05). The main effect of this new Asp49 PLA2 of Bothrops pauloensis venom is on muscle fiber sarcolemma, with avian preparation being less responsive than rodent preparation. The study enhances biochemical and pharmacological characterization of B. pauloensis venom.

Efeito de 13 semanas de treinamento físico militar sobre a composição corporal e o desempenho físico dos alunos da escola preparatória de cadetes do exército

INTRODUCTION: Armies from all over the world acknowledge the importance of good physical fitness for the performance of military duties. The Military Exercise Training (MET) attempts to provide assistance to this search for better physical fitness and performance. OBJECTIVE: To verifying the effect on the body composition and physical performance of the students at ESPCEX (Military School for Preparation of Army Cadets) after 13 weeks of MET. METHODS: The sample was formed by 287 male students from the ESPCEX, whose average age was 18.33 ±1.26. Such students accomplished a boarding school routine, having defined schedules, meals and activities from which they were only released during the weekends. The MET was accomplished five days a week and it comprised both aerobic and resistance training. Measurement of body mass, height, skinfold (triceps, abdominal and suprailiac) was accomplished during pre and post training periods, and the following tests were performed: 12-minutes-run, oblique sit up, arm push up and pull up. Fat percentage, fat-free body mass and fat body mass were calculated using the anthropometric data based on the Guedes 3 skinfold protocol. RESULTS: Significant reduction in fat body mass, fat percentage and in triceptal and abdominal skinfold, as well as increase in suprailiac skinfold and fat-free body mass was observed when anthropometric and body composition data were compared, during the initial and the final periods of training. Significant improvement also occurred in all prformed physical tests, in which better performance was achieved. CONCLUSION: The acquired data suggest that performance of MET 5 days a week brought significantly improved body composition as well as physical performance

Prevalence of malocclusions in the 13-20-year-old categories of football athletes

The dentist can offer athletes improvement in their physical performance through the maintenance of oral health, preventing and treating any and all changes in the stomatognathic system, such as dental malocclusions, that compromise the athletes' performance. The objective of this study is to research the presence of dental malocclusions in athletes of the category between 13 and 20 years of age, from the São Paulo Football Club. 84 athletes participated in this study, dealing with the following topics: molar relation (Angle's classification); presence of overbite; underbite; overcrowding; abnormal spacing; open bite; and anterior, posterior, bilateral and unilateral crossbite; midline deviation and facial type (mesofacial, brachyfacial and dolichofacial). Only one table was made, showing percentages. In regard to Angle's molar relation, 89% are in Class I, 8% in Class II, 3% Class III, 9% of the athletes had overbite, 4% had underbite, 13% had overcrowding and 21% had abnormal spacing. In regard to the bite, 11% presented anterior open bite. In regard to crossbite, 7% presented unilateral crossbite on the right side and 2% on the left side; 5% presented posterior crossbite and 4% anterior crossbite. In regard to midline deviations, 4% presented deviation in the maxilla and 33% in the mandible. In regard to facial type: 39% are dolichofacial, 4% brachyfacial and 57% mesofacial. Based on the results shown, proposals for the implementation of dental, phoniatric, and Ear, Nose and Throat (ENT) practices are already being discussed with the multidisciplinary team of the club involved.

Transiting exoplanets from the CoRoT space mission X. CoRoT-10b: a giant planet in a 13.24 day eccentric orbit

Context. The space telescope CoRoT searches for transiting extrasolar planets by continuously monitoring the optical flux of thousands of stars in several fields of view. Aims. We report the discovery of CoRoT-10b, a giant planet on a highly eccentric orbit (e = 0.53 +/- 0.04) revolving in 13.24 days around a faint (V = 15.22) metal-rich K1V star. Methods. We used CoRoT photometry, radial velocity observations taken with the HARPS spectrograph, and UVES spectra of the parent star to derive the orbital, stellar, and planetary parameters. Results. We derive a radius of the planet of 0.97 +/- 0.07 R(Jup) and a mass of 2.75 +/- 0.16 M(Jup). The bulk density,rho(p) = 3.70 +/- 0.83 g cm(-3), is similar to 2.8 that of Jupiter. The core of CoRoT-10b could contain up to 240 M(circle plus) of heavy elements. Moving along its eccentric orbit, the planet experiences a 10.6-fold variation in insolation. Owing to the long circularisation time, tau(circ) > 7 Gyr, a resonant perturber is not required to excite and maintain the high eccentricity of CoRoT-10b.

A comparative solid state (13)C NMR and thermal study of CO(2) capture by amidines PMDBD and DBN

The present work shows study of the CO(2) capture by amidines DBN and PMDBD using (13)C solid-state NMR and thermal techniques. The solid state (13)C NMR analyses demonstrate the formation of a single PMDBD-CO(2) product which was assigned to stable bicarbonate. In the case of DBN, it is shown that two DBN-CO(2) products are formed, which are suggested to be stable bicarbonate and unstable carbamate. The role of water in the DBN-CO(2) capture as well as the stability of the products to environmental moisture was also investigated. The results suggest that the carbamate formation is favored in dry DBN, but in the presence of water it decompose to form bicarbonate. Thermal analysis shows a good gravimetric CO(2) absorption of DBN. Release of CO(2) was found to be almost quantitative from the PMDBDH(+) bicarbonate about 110 degrees C.

Density functional theory investigation of 3d, 4d, and 5d 13-atom metal clusters

The knowledge of the atomic structure of clusters composed by few atoms is a basic prerequisite to obtain insights into the mechanisms that determine their chemical and physical properties as a function of diameter, shape, surface termination, as well as to understand the mechanism of bulk formation. Due to the wide use of metal systems in our modern life, the accurate determination of the properties of 3d, 4d, and 5d metal clusters poses a huge problem for nanoscience. In this work, we report a density functional theory study of the atomic structure, binding energies, effective coordination numbers, average bond lengths, and magnetic properties of the 3d, 4d, and 5d metal (30 elements) clusters containing 13 atoms, M(13). First, a set of lowest-energy local minimum structures (as supported by vibrational analysis) were obtained by combining high-temperature first- principles molecular-dynamics simulation, structure crossover, and the selection of five well-known M(13) structures. Several new lower energy configurations were identified, e. g., Pd(13), W(13), Pt(13), etc., and previous known structures were confirmed by our calculations. Furthermore, the following trends were identified: (i) compact icosahedral-like forms at the beginning of each metal series, more opened structures such as hexagonal bilayerlike and double simple-cubic layers at the middle of each metal series, and structures with an increasing effective coordination number occur for large d states occupation. (ii) For Au(13), we found that spin-orbit coupling favors the three-dimensional (3D) structures, i.e., a 3D structure is about 0.10 eV lower in energy than the lowest energy known two-dimensional configuration. (iii) The magnetic exchange interactions play an important role for particular systems such as Fe, Cr, and Mn. (iv) The analysis of the binding energy and average bond lengths show a paraboliclike shape as a function of the occupation of the d states and hence, most of the properties can be explained by the chemistry picture of occupation of the bonding and antibonding states.

Transition-metal 13-atom clusters assessed with solid and surface-biased functionals

First-principles density-functional theory studies have reported open structures based on the formation of double simple-cubic (DSC) arrangements for Ru(13), Rh(13), Os(13), and Ir(13), which can be considered an unexpected result as those elements crystallize in compact bulk structures such as the face-centered cubic and hexagonal close-packed lattices. In this work, we investigated with the projected augmented wave method the dependence of the lowest-energy structure on the local and semilocal exchange-correlation (xc) energy functionals employed in density-functional theory. We found that the local-density approximation (LDA) and generalized-gradient formulations with different treatment of the electronic inhomogeneities (PBE, PBEsol, and AM05) confirm the DSC configuration as the lowest-energy structure for the studied TM(13) clusters. A good agreement in the relative total energies are obtained even for structures with small energy differences, e. g., 0.10 eV. The employed xc functionals yield the same total magnetic moment for a given structure, i.e., the differences in the bond lengths do not affect the moments, which can be attributed to the atomic character of those clusters. Thus, at least for those systems, the differences among the LDA, PBE, PBEsol, and AM05 functionals are not large enough to yield qualitatively different results.

The role of electron localization in the atomic structure of transition-metal 13-atom clusters: the example of Co(13), Rh(13), and Hf(13)

The crystalline structure of transition-metals (TM) has been widely known for several decades, however, our knowledge on the atomic structure of TM clusters is still far from satisfactory, which compromises an atomistic understanding of the reactivity of TM clusters. For example, almost all density functional theory (DFT) calculations for TM clusters have been based on local (local density approximation-LDA) and semilocal (generalized gradient approximation-GGA) exchange-correlation functionals, however, it is well known that plain DFT fails to correct the self-interaction error, which affects the properties of several systems. To improve our basic understanding of the atomic and electronic properties of TM clusters, we report a DFT study within two nonlocal functionals, namely, the hybrid HSE (Heyd, Scuseria, and Ernzerhof) and GGA + U functionals, of the structural and electronic properties of the Co(13), Rh(13), and Hf(13) clusters. For Co(13) and Rh(13), we found that improved exchange-correlation functionals decrease the stability of open structures such as the hexagonal bilayer (HBL) and double simple-cubic (DSC) compared with the compact icosahedron (ICO) structure, however, DFT-GGA, DFT-GGA + U, and DFT-HSE yield very similar results for Hf(13). Thus, our results suggest that the DSC structure obtained by several plain DFT calculations for Rh(13) can be improved by the use of improved functionals. Using the sd hybridization analysis, we found that a strong hybridization favors compact structures, and hence, a correct description of the sd hybridization is crucial for the relative energy stability. For example, the sd hybridization decreases for HBL and DSC and increases for ICO in the case of Co(13) and Rh(13), while for Hf(13), the sd hybridization decreases for all configurations, and hence, it does not affect the relative stability among open and compact configurations.
