    OBJECTIVES: To describe and correlate tongue force and grip strength measures and to verify the association of these measures with water swallowing in different age groups. METHOD: Tongue force was evaluated using the Iowa Oral Performance Instrument and grip strength using the Hand Grip in 90 normal individuals, who were divided into three groups: young (18-39 years old), adult (40-59 years old) and elderly (above 60 years old) individuals. The time and number of swallows required for the continuous ingestion of 200 ml of water were also measured. RESULTS: A reduction in tongue force and grip strength, as well as an increase in the time required to drink 200 ml of water, were observed with increasing participant age. There was no difference in the number of swallows among the three groups. A correlation was observed between reductions in tongue force and grip strength in the groups of young and elderly individuals. CONCLUSION: There were differences in the measures of tongue force in young, adult and elderly individuals. Greater variations within these differences were observed when repeated movements were performed; in addition, a decrease in strength was associated with an increase in age. The decrease in tongue force among the elderly was offset by the increase in time needed to swallow the liquid. There was an association between the measures of tongue force and grip strength in the different age groups. The results of this study can be applied clinically and may act as a basis for guidelines in healthy or vulnerable elderly populations

    O câncer de mama (CM) é classificado como um carcinoma, por se originar em células epiteliais a partir da proliferação ductal. Apesar do aumento acelerado das taxas de incidência de câncer nos últimos cinco anos, a taxa de sobrevida aumentou de 30% para aproximadamente 80% nos países desenvolvidos. A crescente população de sobreviventes requer acompanhamentos e cuidados especializados, posto que o câncer e o próprio tratamento promovem uma série de alterações fisiológicas que afetam a qualidade de vida e a capacidade funcional de sobreviventes de CM. O treinamento de força é uma das estratégias mais utilizadas para atenuar os efeitos colaterais tardios e persistentes do câncer, reduzindo a fadiga e a caquexia. O objetivo desta pesquisa foi analisar os efeitos de 8 semanas de treinamento em circuito na força muscular, na percepção de fadiga, na qualidade de vida e na funcionalidade de sobreviventes de câncer de mama. Para isso, 9 sobreviventes de CM foram submetidas a um programa de treinamento de força de oito semanas. Antes e após o programa de treinamento, as sobreviventes foram avaliadas quanto a força muscular, a percepção de fadiga, a qualidade de vida e a funcionalidade. Houve uma redução significativa após o protocolo de treinamento, na fadiga geral (p = 0,02), fadiga física (p = 0,01), redução da atividade (p = 0,002) e na redução da motivação (p = 0,01). Além disso, houve um aumento significativo na resistência à fadiga muscular (p 0,001). Houve também uma melhora significativa na funcionalidade, demonstrada por uma redução do TUG (p 0,001) e um aumento do desempenho no teste de “sentar e levantar” (p 0,001). O treinamento de força em circuito também promoveu um aumento significativo da qualidade de vida nos domínios de capacidade funcional, limitação por aspectos físicos, vitalidade, aspectos sociais, limitações por aspectos emocionais e saúde mental, se mostrando uma estratégia efetiva e positiva para aumentar a qualidade de vida de sobreviventes de câncer de mama. Conclui-se que, a partir dos resultados da presente pesquisa, o treinamento em circuito proporciona resultados significativos nas variáveis fadiga geral, fadiga física, fadiga muscular, redução da atividade, redução da motivação e funcionalidade, promovendo uma maior qualidade de vida para sobreviventes de câncer de mama

    EpIG‐DB: A database of vascular epiphyte assemblages in the Neotropics

    Vascular epiphytes are a diverse and conspicuous component of biodiversity in tropical and subtropical forests. Yet, the patterns and drivers of epiphyte assemblages are poorly studied in comparison with soil‐rooted plants. Current knowledge about diversity patterns of epiphytes mainly stems from local studies or floristic inventories, but this information has not yet been integrated to allow a better understanding of large‐scale distribution patterns. EpIG‐DB, the first database on epiphyte assemblages at the continental scale, resulted from an exhaustive compilation of published and unpublished inventory data from the Neotropics. The current version of EpIG‐DB consists of 463,196 individual epiphytes from 3,005 species, which were collected from a total of 18,148 relevés (host trees and ‘understory’ plots). EpIG‐DB reports the occurrence of ‘true’ epiphytes, hemiepiphytes and nomadic vines, including information on their cover, abundance, frequency and biomass. Most records (97%) correspond to sampled host trees, 76% of them aggregated in forest plots. The data is stored in a TURBOVEG database using the most up‐to‐date checklist of vascular epiphytes. A total of 18 additional fields were created for the standardization of associated data commonly used in epiphyte ecology (e.g. by considering different sampling methods). EpIG‐DB currently covers six major biomes across the whole latitudinal range of epiphytes in the Neotropics but welcomes data globally. This novel database provides, for the first time, unique biodiversity data on epiphytes for the Neotropics and unified guidelines for future collection of epiphyte data. EpIG‐DB will allow exploration of new ways to study the community ecology and biogeography of vascular epiphytes

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

    Get PDF
    One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
