The green infrastructure of a highly-urbanized neotropical city : the role of the urban vegetation in preserving native biodiversity

The composition of the urban vegetation that comprises the green infrastructure of a highly urbanized Neotropical city was mapped and described in order to assess how it can be used to preserve and maintain urban biodiversity. Supervised classification was used, followed by Map Algebra methodology, to identify the elements that comprise the green infrastructure of the southern region of Belo Horizonte (Minas Gerais, Brazil). Species composition of the street trees community was also assessed. Almost half of the study area is occupied by 12 types of woody and herbaceous vegetation, composed mostly by urban parks and gardens. Forty-one percent of the almost 90,000 street trees is composed by 10 species from which only four are native. These results show that the green infrastructure of this urban landscape is comprised by a large amount of different types of green elements, and has a great potential for biodiversity conservation. However, management strategies are needed such as better planning of the urban afforestation process, increasing street tree species richness. This study is the first step towards a better understanding of how such urban landscape influences local biodiversity

TRY plant trait database - enhanced coverage and open access

Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Relationship between functional fitness, medication costs and mood in elderly people

Objective: to verify if functional fitness (FF) is associated with the annual cost of medication consumption and mood states (MSt) in elderly people. Methods: a cross-sectional study with 229 elderly people aged 65 years or more at Santa Casa de Misericórdia de Coimbra, Portugal. Seniors with physical and psychological limitations were excluded, as well as those using medication that limits performance on the tests. The Senior Fitness Test was used to evaluate FF, and the Profile of Mood States - Short Form to evaluate the MSt. The statistical analysis was based on Mancova, with adjustment for age, for comparison between men and women, and adjustment for sex, for comparison between cardiorespiratory fitness quintiles. The association between the variables under study was made with partial correlation, controlling for the effects of age, sex and body mass index. Results: an inverse correlation between cardiorespiratory fitness and the annual cost of medication consumption was found (p < 0.01). FF is also inversely associated with MSt (p < 0.05). Comparisons between cardiorespiratory fitness quintiles showed higher medication consumption costs in seniors with lower aerobic endurance, as well as higher deterioration in MSt (p < 0.01). Conclusion: elderly people with better FF and, specifically, better cardiorespiratory fitness present lower medication consumption costs and a more positive MSt

Biosilicate (R)-gelatine bone scaffolds by the foam replica technique: development and characterization

The development of bioactive glass-ceramic materials has been a topic of great interest aiming at enhancing the mechanical strength of traditional bioactive scaffolds. In the present study, we test and demonstrate the use of Biosilicate® glass-ceramic powder to fabricate bone scaffolds by the foam replica method. Scaffolds possessing the main requirements for use in bone tissue engineering (95% porosity, 200–500 μm pore size) were successfully produced. Gelatine coating was investigated as a simple approach to increase the mechanical competence of the scaffolds. The gelatine coating did not affect the interconnectivity of the pores and did not significantly affect the bioactivity of the Biosilicate® scaffold. The gelatine coating significantly improved the compressive strength (i.e. 0.80 ± 0.05 MPa of coated versus 0.06 ± 0.01 MPa of uncoated scaffolds) of the Biosilicate® scaffold. The combination of Biosilicate® glass-ceramic and gelatine is attractive for producing novel scaffolds for bone tissue engineering

Cuidadores informais de idosos em pós-operatório de cirurgia de fêmur proximal: prevenção de novas quedas

The objectives of this study were to investigate the sociodemographic characteristics of informal caregivers of elderly persons who had undergone surgery for hip fractures caused by a fall, explore the level of caregiver's knowledge regarding fall prevention, and assess the relationship between this knowledge and the use of preventative measures in practice. This investigation consists of a cross-sectional study using nonprobability sampling methods conducted over a period of 12 months and involving 89 caregivers. The majority of caregivers were female (76.4%) and sons or daughters of the patients (64%). Environmental modification was the predominant preventative measure used by caregivers (88.2%). 58.1% of caregivers believed it was possible to prevent falls in the elderly and there was a significant association (p = 0,002) between believing it was possible to prevent falls and carrying out modifications in the home and/or to the daily routine of the older person. Informal caregivers with wide or partial knowledge of fall prevention put preventative measures into practice. These findings demonstrate that the number of falls among older persons could be significantly reduced if health care programmes widened their actions to include the guiding principles of the WHO falls prevention model.Os objetivos foram caracterizar sociodemograficamente os cuidadores informais de idosos vítimas de queda seguida por fratura de fêmur proximal e verificar o conhecimento mínimo que possuíam acerca da prevenção de novas quedas, assim como caracterizar a relação entre esse conhecimento e o emprego de medidas preventivas. Trata-se de estudo transversal, com amostragem intencional, realizado em 12 meses, incluindo 89 cuidadores. Predominaram cuidadores do sexo feminino (76,4%) e filhas(os) (64%). A modificação ambiental foi a medida preventiva predominante apontada por eles (88,2%). Houve associação significativa (p = 0,002), entre os 58,1% dos cuidadores que achavam ser possível prevenir quedas e os relatos sobre mudanças na casa e/ou rotina do idoso. Observou-se que cuidadores informais que apresentavam conhecimento sobre prevenção de quedas em idosos, mesmo que incompletos, empregavam medidas de prevenção para novos eventos. Esses achados sinalizam que o número de quedas entre idosos pode ser reduzido significantemente se os programas de atenção à saúde ampliarem suas ações apoiando-as no modelo de prevenção de quedas da Organização Mundial de Saúde.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Estadual Paulista (Unesp), Departamento de Enfermagem, Faculdade de Medicina de Botucatu (FMB), Distrito de Rubião Júnior snº, Centro. 18618-970, Botucatu SP BrasilUniversidade Estadual Paulista (Unesp), Departamento de Cirurgia e Ortopedia, FBM, Unesp.Universidade Estadual Paulista (Unesp), Departamento de Enfermagem, Faculdade de Medicina de Botucatu (FMB), Distrito de Rubião Júnior snº, Centro. 18618-970, Botucatu SP BrasilUniversidade Estadual Paulista (Unesp), Departamento de Cirurgia e Ortopedia, FBM, Unesp
