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

Quantitative RT-PCR analysis of differentially expressed genes in Quercus suber in response to Phytophthora cinnamomi infection

cDNA-AFLP methodology was used to gain insight into gene fragments differentially present in the mRNA profiles of Quercus suber roots infected with zoospores of Phytophthora cinnamomi at different post challenge time points. Fifty-three transcript-derived fragments (TDFs) were identified and sequenced. Six candidate genes were selected based on their expression patterns and homology to genes known to play a role in defence. They encode a cinnamyl alcohol dehydrogenase2 (QsCAD2), a protein disulphide isomerase (QsPDI), a CC-NBS-LRR resistance protein (QsRPc), a thaumatin-like protein (QsTLP), a chitinase (QsCHI) and a 1,3-β-glucanase (QsGlu). Evaluation of the expression of these genes by quantitative polymerase chain reaction (qPCR) revealed that transcript levels of QsRPc, QsCHI, QsCAD2 and QsPDI increased during the first 24 h post-inoculation, while those of thaumatin-like protein decreased. No differential expression was observed for 1,3-β-glucanase (QsGlu).Four candidate reference genes, polymerase II (QsRPII), eukaryotic translation initiation factor 5A (QsEIF-5A), β-tubulin (QsTUB) and a medium subunit family protein of clathrin adaptor complexes (QsCACs) were assessed to determine the most stable internal references for qRT-PCR normalization in the Phytophthora-Q. suber pathosystem in root tissues. Those found to be more stable, QsRPII and QsCACs, were used as internal reference in the present work.Knowledge on the Quercus defence mechanisms against biotic stress is scarce. This study provides an insight into the gene profiling of a few important genes of Q. suber in response to P. cinnamomi infection contributing to the knowledge of the molecular interactions involving Quercus and root pathogens that can be useful in the future to understand the mechanisms underlying oak resistance to soil-borne oomycetes.Peer Reviewe

Social representations of needlestick injuries

OBJECTIVES: understand the Social Representations about needlestick injuries elaborated by Nursing Technicians and analyze how these representations influence their conducts. METHOD: the data, obtained by interviews, were processed using ALCESTE software and their analysis was based on Serge Moscovici's Social Representations Theory. RESULTS: it was evidenced that, after the accident, these professionals take care of the affected area. Then, they report the accident, motivated by the fear of catching HIV and hepatitis. The different feelings experienced are due to this fear and the way they were forwarded by the institution, reflecting in the cause they attribute to their accident. CONCLUSIONS: it was verified that knowledge about the accident as a whole is very incipient in this professional group, demanding continuing education and greater emphasis on this subject in professional training. It is expected that this study draws public authorities and health institutions' attention to the problem and that it modifies Nursing Technicians' Social Representations about percutaneous exposure.OBJETIVOS: Comprender las Representaciones Sociales de los accidentes con materiales corto-punzantes, elaboradas por Técnicos de Enfermería, así como analizar de que modo esas representaciones influencian las conductas de eses profesionales. MÉTODO: Los datos, logrados por medio de entrevistas, fueron procesados por el software ALCESTE y el análisis de los mismos fue basado en la Teoría de las Representaciones Sociales de Serge Moscovici. RESULTADOS: se evidenció que, después de accidentarse, los Técnicos de Enfermería cuidan del área afectada. Enseguida, notifican el accidente, motivados por el miedo de que contraigan HIV y hepatitis. Los diversos sentimientos vividos son consecuentes de ese miedo y de la manera como fueron encaminados por la institución, reflejando en la causa que ellos atribuyen a su accidente. CONCLUSIONES: se constató que hay un conocimiento bastante incipiente por parte de esa clase profesional sobre el accidente como un todo, habiendo necesidad de una educación continuada y mayor énfasis en cuanto a ese asunto durante la formación profesional. Se espera que ese estudio llame la atención de los órganos gubernamentales e instituciones de salud sobre el problema y modifique las Representaciones Sociales de la exposición percutánea de los Técnicos de Enfermería.OBJETIVOS: compreender as representações sociais dos acidentes com materiais perfurocortantes, elaboradas por técnicos de enfermagem, bem como analisar de que modo essas representações influenciam as condutas desses profissionais.

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

Quality of life of caregivers for patients of cerebrovascular accidents: association of (socio-demographic) characteristics and burden

OBJECTIVE Investigating the association between quality of life with socio-demographic characteristics and the burden of caregivers for individuals with cerebrovascular accident sequelae. METHOD A descriptive, cross-sectional study with a sample composed of 136 caregivers. For data collection, a semi-structured questionnaire, the Barthel, Burden Interview and Short-Form-36 scales were used. Correlation analysis, t-Student test and F-test were used for the analysis in order to compare averages. RESULTS Significant averages in quality of life were demonstrated in association with female caregivers and those over 60 years in the field 'functional capacity,' and in the domains of 'mental health' and 'vitality' for those with higher income. Regarding burden association, the highlighted areas were 'functional capacity,' 'physical aspects,' 'emotional aspects' and 'pain.' CONCLUSION The creation of public policies and social support to effectively reduce the burden on caregivers is a necessity
