The Spatial parameters of gait and their association with falls, functional decline and death in older adults: a prospective study

Association between spatial gait parameters and adverse health outcomes in the elderly has not been sufficiently studied. The goal of this study is to evaluate whether the stride length or the step width predict falls, functional loss and mortality. We conducted a prospective cohort study on a probabilistic sample of 431 noninstitutionalized, older-than-64-years subjects living in Spain, who were followed-up for five years. In the baseline visit, spatial gait parameters were recorded along with several control variables, with special emphasis on known medical conditions, strength, balance and functional and cognitive capacities. In the follow-up calls, vital status, functional status and number of falls from last control were recorded. We found that a normalized-to-height stride length shorter than 0.52 predicted recurrent falls in the next 6 months with 93% sensitivity and 53% specificity (AUC: 0.72), and in the next 12 months with 81% sensitivity and 57% specificity (AUC: 0.67). A normalized stride length <0.5 predicted functional loss at 12 months with a sensitivity of 79.4% and specificity of 65.6% (AUC: 0.75). This predictive capacity remained independent after correcting for the rest of risk factors studied. Step-with was not clearly related to functional loss or falls. Both shorter normalized stride length (OR1.56; AUC: 0.62; p < 0.05) and larger step width (OR1.42; AUC: 0.62; p < 0.05) were associated with risk of death at 60 months; however, none of them remained as independent predictor of death, after correcting for other risk factors. In summary, spatial gait parameters may be risk markers for adverse outcomes in the elderly. Step length is independently associated with functional loss and falls at one year, after correction for numerous known risk factors

A supressão do efeito suspensivo do recurso de apelação: uma investigação sobre seus reflexos na celeridade processual e segurança jurídica, a partir de estudos de casos e dados obtidos junto ao Tribunal de Justiça do Rio de Janeiro

Esta dissertação de mestrado tem o objetivo de estudar o efeito suspensivo do recurso de apelação e seus reflexos no sistema jurídico brasileiro. Com efeito, busca-se analisar as possíveis consequências da supressão do próprio efeito suspensivo sobre o tempo de duração dos processos e quanto a possível insegurança jurídica causada pela ausência da suspensão dos julgados de primeira instância. Sustenta-se neste trabalho que a supressão do efeito suspensivo pode ser uma proposta para aumentar a celeridade na tramitação dos processos no Brasil, sem causar problemas de segurança jurídica. Em primeiro lugar, descreve-se o problema de investigação e suas proposições. O primeiro capítulo apresenta a judicialização das relações sociais e, por conseguinte, a multiplicação do número de ações distribuídas e a crescente exigência pela efetividade da prestação jurisdicional. Neste mesmo capítulo o trabalho se ocupa em apreciar dos dados obtidos junto ao Tribunal de Justiça do Rio de Janeiro e com a análise qualitativa de casos típicos que demonstram o uso do efeito suspensivo tão somente para procrastinar o tempo de duração do processo bem como para barganhar um possível acordo vantajoso para o devedor. Em seguida, apreciamos os Princípios constitucionais da Segurança Jurídica e da Efetividade e Celeridade da Prestação Jurisdicional indicando o marco teórico de cada princípio. O segundo capítulo descreve conceito de sentença e seus efeitos, levando-se em consideração as últimas reformas processuais. Após, estuda-se a suposta estabilidade do sistema jurídico com a aplicação do efeito suspensivo, abordando o duplo grau de jurisdição como garantia constitucional. Posteriormente, indicamos a utilização estratégica do efeito suspensivo pelos atores (réus) do processo. O terceiro capítulo destina-se a apontar a legislação estrangeira e seus respectivos fundamentos jurídicos que influenciaram o nosso ordenamento jurídico, bem como a colaboração do autor em sugerir uma nova proposta de lei. Aproveitamos a oportunidade para trazer á baila as possíveis alterações oriundas do projeto do novo Código de Processo Civil e suas aspirações para dirimir os obstáculos que causam o longo tempo de duração dos processos. Por fim, apresentamos as considerações finais sobre a hipótese de supressão do efeito suspensivo como meio de alcançar a redução do tempo de duração do processo mantendo-se as garantias constitucionais da ampla defesa e do devido processo legal. Com efeito, demonstra-se que não há qualquer violação ao Princípio da Segurança Jurídica.This Master's degree dissertation aims to study the effect of suspending the appeal resource and its reflection in the Brazilian legal system. Indeed, it was analyzed the possible consequences of suppression of the very suspensory effect over the processes time span and for possible legal uncertainty caused by the absence of suspension of first instance trials. This work maintains that the withdrawal of the suspensory effect may be a proposal to increase the speed in dealing with legal cases in Brazil without causing legal safety problems. First, it is described the investigation issue and its propositions. The first chapter introduces the legalization of social relations and therefore, the multiplying number of distributed legal cases and the growing requirement for adjudication effectiveness. In this same chapter, the work focuses on assessing data obtained from the Rio de Janeiro Court with typical cases qualitative analysis that show the use of suspensive effect only to procrastinate the process time length as well as to bargain a possible beneficial agreement to the debtor. Following, it is appreciated the constitutional principles of legal safety and the effectiveness and speed of Jurisdictional Provision indicating the theoretical framework of each principle. The second chapter describes the concept of sentence and its effects, taking into account the last procedural reforms. Following, it is studied the supposed stability of the legal system with the application of the suspensive effect, addressing the jurisdiction double degree as constitutional guarantee. After it is indicated the strategic use of the suspensive effect by the process actors (defendants) The third chapter aims to point out to foreign legislation and its legal foundations that have influenced our legal planning as well as the author collaboration in suggesting a new law proposal. It is an opportunity here to present the possible alterations from the project of the New Code of Civil Procedure and its aspirations to solve obstacles that cause the long time span of processes duration. Finally final considerations are presented on the suppression assumption of the suspensive effect as means of reaching the time span processes reduction while maintaining the constitutional guarantees of broad legal defense and due legal process. In fact, it has been demonstrated that there isn't any violation to the Principle of Legal Safety

Geologia e geocronologia da Suite Metamorfica Colorado e suas encaixantes, SE de Rondonia: implicacoes para a evolucao Mesoproterozoica do SW do Craton Amazonico

Combined geochronological (U-Pb, Ar/ Ar, and Rb-Sr) geological data help define an important tectonomagmatic event in the Colorado do Oeste and Cabixi regions, southeastern Rondônia, Brazil, and characterize the Colorado Metamorphic Suite (CMS), well represented by rock assemblages which experienced deformation and metamorphic recrystallization (upper-amphibolite facies). The suite is composed of: 1) porphyritic monzogranite associated with amphibolite (bimodal magmatism), 2) interlayered clastic and chemical metasedimentary rocks (sillimanite schists and iron formation), 3) muscovite-garnet leucogranite, and 4) mafic-ultramafic intrusive rocks. The CMS mafic rocks occur as undeformed isolated bodies of layered coarse-grained metagabbro, still preserving typical cumulate igneous texture. U-Pb zircon isotopic data for three fractions of sample RO-10 define a discordia with an upper intercept (crystallization) age of 1352 + 4/-3 Ma (MSWD = 0.18). The porphyritic ortogneisses (RO-15; monzogranite and amphibolite) yielded a Rb-Sr whole rock isochron age of 1360 ± 45 Ma, and Sr/Sr = 0.7040 ± 0.0012 (MSWD = 9.2). One sample of aplite that is subparallel to the main regional foliation has furnished an age of 1360 ± 13 Ma. The Ar/Ar data for muscovite from a anatectic leucogranite (RO-14) yielded plateau ages of 1312 ± 3 Ma (grain 1), and 1303 ± 2 Ma/1305 ± 2 Ma (grain 2). Grain 3 presented an heterogeneous isotopic spectrum, the integrated age being 1289 ± 2 Ma. Hornblende from two amphibolite samples yielded Ar/ Ar plateau ages of 1313 ± 4 Ma; 1313 ± 6 Ma and 1312 ± 3 Ma (RO-18), and 1325 ± 3 Ma; 1326 ± 2 Ma; 1330 ± 3 Ma (RO-19). The weighted-mean age is 1319 ± 10 Ma, and is interpreted as the best estimated age for regional metamorphic cooling. These data suggest that southeastern Rondônia was affected by a tectonomagmatic event at ca. 1.36 - 1.32 Ga, predating the evolution of the Nova Brasilândia Terrane (1215 - 1110 Ma). However, the unequivocal characterization of an orogeny refered to the time interval 1.36 - 1.32 Ga is still uncertain due to scarcity of geochronological data in the region. Similar ages are reported for correlatable intrusive rocks which cut the polydeformed basement rocks of central Rondônia. Thus, these ages are compatible with available Mesoproterozoic tectonic models for the SW Amazonian Craton

Extratemporal abnormalities in phosphorus magnetic resonance spectroscopy of patients with mesial temporal sclerosis

ABSTRACT Objective We evaluated extratemporal metabolic changes with phosphorus magnetic resonance spectroscopy (31P-MRS) in patients with unilateral mesial temporal sclerosis (MTS). Method 31P-MRS of 33 patients with unilateral MTS was compared with 31 controls. The voxels were selected in the anterior, posterior insula-basal ganglia (AIBG, PIBG) and frontal lobes (FL). Relative values of phosphodiesters- PDE, phosphomonoesters-PME, inorganic phosphate - Pi, phosphocreatine- PCr, total adenosine triphosphate [ATPt = γ- + a- + b-ATP] and the ratios PCr/ATPt, PCr/γ-ATP, PCr/Pi and PME/PDE were obtained. Results We found energetic abnormalities in the MTS patients compared to the controls with Pi reduction bilaterally in the AIBG and ipsilaterally in the PIBG and the contralateral FL; there was also decreased PCr/γ-ATP in the ipsilateral AIBG and PIBG. Increased ATPT in the contralateral AIBG and increased γ-ATP in the ipsilateral PIBG were detected. Conclusion Widespread energy dysfunction was detected in patients with unilateral MTS
