    DEFORESTATION, COMMUNITY WELLNESS AND SUSTAINABLE DEVELOPMENT: an integrated analysis in Sao Tome and Principe - AfricaDÉFORESTATION, BIEN-ÊTRE COMMUNAUTAIRE ET DÉVELOPPEMENT DURABLE: une analyse intégrée à Sao Tomé-et- Principe – AfriqueA preocupação com a natureza, frente aos impactos negativos provocados pela ação humana, tem sido objeto de grande reflexão internacional. Vários eventos já foram realizados sobre a matéria, mormente apelando à conservação dos recursos naturais e à necessidade do desenvolvimento sustentável. Entretanto, atrocidades contra a natureza têm defasado fauna e flora em diversos lugares, como é caso de São Tomé e Príncipe. Eis o objeto do presente trabalho: analisa-se a relação socioambiental no país, sobretudo as causas e efeitos da acentuada prática do desmatamento. E para tanto, usou-se uma metodologia centralizada na revisão da literatura complementada com uma análise interpretativa e reflexiva sobre os problemas ambientais. Assim, convém destacar subsídios teóricos usados: Eiffert (2010); Castro et al. (2005); Filho (2000); Rodriguez et al. ( 2009); Souza et al. (2012). Outrossim, diplomas legais que dispõem sobre a matéria foram de capital importância, sobretudo a Constituição da República Democrática de São Tomé e Príncipe 2003 e da Lei n.º 05/2001, Lei de Florestas. No decorrer da análise, constatou-se que o fator desmatamento registrado, em parte, está condicionado ao fator econômico (pobreza), e isso impôs à necessidade da reflexão socioeconômica em conjugação com o fator socioambiental. Por fim, instiga-se a importância de planos estratégicos para uso sustentável de recursos naturais, visando à estabilidade ecológica local. São essas reflexões que deram sustentação e especificidade no desenrolar do presente estudo, o qual se espera ensejar mais reflexões e debates sobre a matéria em epígrafe.Palavras-chave: Impacto Ambiental; Bem-estar Comunitário; São Tomé e Príncipe.ABSTRACTThe concern with nature, in the face of the negative impacts caused by human action, has been the object of great international reflection. Several events have already been held on the subject, especially appealing to the conservation of natural resources and the need for sustainable development. However, atrocities against nature have lagged fauna and flora in several places, as is the case of São Tomé and Príncipe. The objective of the present study is to analyze the socio-environmental relationship in the country, especially the causes and effects of the marked deforestation practice. For this purpose, a centralized methodology was used in the review of the literature and complemented with an interpretative and reflexive analysis on the environmental problems. Thus, it is worth mentioning the theoretical subsidies used: Eiffert (2010); Castro et al. (2005); Filho (2000); Rodriguez et al. (2009); Souza et al. (2012). In addition, the legal provisions on this matter were of paramount importance, especially the Constitution of the Democratic Republic of São Tomé and Príncipe 2003 and Law no. 05/2001, Law on Forests. In the course of the analysis, it was found that the recorded deforestation factor, in part, is conditioned to the economic factor (poverty), and this imposed the need for socioeconomic reflection in conjunction with the socio-environmental factor. Finally, the importance of strategic plans for the sustainable use of natural resources is instigated, aiming at the local ecological stability. It is these reflections that gave support and specificity in the course of the present study, which is expected to lead to more reflections and debates on the subject in question.Keywords: Environmental Impact; Community Well-being; Sao Tome and Principe.RÉSUMÉLa préoccupation de la nature, face aux impacts négatifs causés par l'action humaine, a fait l'objet d'une grande réflexion internationale. Plusieurs événements ont déjà eu lieu sur le sujet, en particulier pour la conservation des ressources naturelles et la nécessité d'un développement durable. Cependant, les atrocités contre la nature ont retardé la faune et la flore dans plusieurs endroits, comme c'est le cas à São Tomé et Príncipe. L'objectif de la présente étude est d'analyser les relations socio-environnementales dans le pays, en particulier les causes et les effets de la pratique de la déforestation. À cette fin, une méthodologie centralisée a été utilisée dans l'examen de la littérature et complétée par une analyse interprétative et réflexive des problèmes environnementaux. Ainsi, il convient de mentionner les subventions théoriques utilisées: Eiffert (2010); Castro et al. (2005); Filho (2000); Rodriguez et al. (2009); Souza et al. (2012). En outre, les dispositions légales sur cette question revêtaient une importance primordiale, en particulier la Constitution de la République démocratique de São Tomé et Príncipe de 2003 et la Loi n ° 05/2001, Loi sur les forêts. Au cours de l'analyse, on a constaté que le facteur de déforestation enregistré, en partie, est conditionné au facteur économique (pauvreté), ce qui a imposé la nécessité d'une réflexion socio-économique en conjonction avec le facteur socio-environnemental. Enfin, l'importance des plans stratégiques pour l'utilisation durable des ressources naturelles est instigée, en vue de la stabilité écologique locale. Ce sont ces réflexions qui ont apporté un soutien et une spécificité au cours de la présente étude, ce qui devrait conduire à plus de réflexions et de débats sur le sujet en question.Mots-clés: Impact Environnemental; Bien-être Communautaire ; Sao Tomé-et-Principe

    ERITEMA NODOSO – MANIFESTAÇÃO RARA DE LINFOMA NÃO-HODGKI

    Get PDF
    Erythema nodosum (EN) is a panniculitis that presents with painful erythematous nodular lesions, pre- ferentially located on the extensor surface of the legs. EN is generally self-limited and chronic or recurrent lesions are rare. Its most common causes are streptococcal pharyngitis, sarcoidosis, inflammatory bowel disease and tuberculosis. A 73-year-old woman presented with recurrent EN with a year of evolution, and the etiological investigation excluded the most frequent causes. The patient underwent upper endoscopy for epigastric pain complaints revealing a gastric infiltrative process. The biopsy was consistent with a diffuse large B-cell lymphoma. Although rare, the association between lymphoma and recurrent EN is described in the literature, and EN may precede de diagnosis of lymphoma by months. Non-Hodgkin lymphoma should therefore be considered in the etiology of EN, especially in cases of persistent or recurrent EN. KEYWORDS – Erythema nodosum; Lymphoma, non-Hodgkin. O eritema nodoso (EN), paniculite que se apresenta com lesões nodulares eritematosas dolorosas, lo- calizadas preferencialmente à face extensora das pernas, é geralmente autolimitado e a cronicidade ou recorrência das lesões é rara. A sua etiologia é variada, sendo as causas mais comuns a faringite estreptocócica, a sarcoidose, a doença inflamatória intestinal e a tuberculose. Uma mulher de 73 anos apresentou-se na consulta de Medicina Interna com quadro de EN recorrente com um ano de evolução, tendo a investigação etiológica excluído as causas mais frequentes. Por queixas de epigastralgias realizou endoscopia digestiva que detetou um processo infiltrativo gástrico. A biopsia revelou um linfoma B difuso de grandes células. Apesar de rara, está descrita na literatura a associação entre linfoma e EN recorrente, podendo estas lesões cutâneas preceder em meses o diagnóstico daquela neoplasia. O linfoma não-Hodgkin deve portanto ser considerado como hipótese etiológica, principalmente nos casos de EN persistente ou recorrente. PALAVRAS-CHAVE – Eritema nodoso; Linfoma não-Hodgkin.

    The objective of the present study was to analyze and compare the setter's decision-making (DM) in the offensive construction of the side-out (attack from the reception) in high-level men's volleyball. The sample consisted of the analysis of 132 games of the Brazilian men's volleyball Super-League 2021/2022, with 22 games for each team. The results showed that the eigenvector values were higher for setting to position 3, central attacker next to the setter, simple block, and obtaining the attack point. In addition, the setter's DM was similar between teams, suggesting that the game strategies aim to provide subsidies for the setter to make the decisions according to the game context in a flexible way and generate benefits for the attackers about the number of blockers, being that under ideal conditions and due to the lifter's correct choices in distribution, central blockers avoid anticipating the setting, and this fact allows the conditions of a single block or double-broken blocks in most cases. As a practical application, setting for the central attacker in position 3 becomes an interesting option for point acquisition and is capable of influencing the number of blockers, as well as the optimal blocking condition. Another application would be for the central attacker to position themselves close to the setter, a strategy that would enable the use of the "pipe" attack in other areas of the court with lower defensive blocking power.9E1A-F9DD-3EB8 | Filipe Manuel ClementeN/

    Healthcare-associated infections are one of the major concerns worldwide. This study presents the development and the validation process of the InovSafeCare scale and aimed at identifying and measuring the ecosystem variables related to healthcare-associated infection (HCAI) prevention and control practices in European nurse students. Qualitative and quantitative approaches were used to (1) elaborate an item pool related to the educational environment, the healthcare setting environment, and the attitudes, beliefs, and performance of the nursing students regarding HCAI prevention and control and (2) analyze psychometric properties of the scale using factor analysis. The validated InovSafeCare scale was applied to undergraduate nursing students of five European Higher Education Institutions. The partial least square structural equation modeling (PLS-SEM) method with SMART-PLS3 software was used. The study sample consists of 657 nursing students, who responded a self-report inventory. From the analyzed data were identified 14 factors. The InovSafeCare scale reveals good validity and reliability of the dimensions in different European countries.info:eu-repo/semantics/publishedVersio

    SELNET clinical practice guidelines for bone sarcoma

    Bone sarcoma are infrequent diseases, representing < 0.2% of all adult neoplasms. A multidisciplinary management within reference centers for sarcoma, with discussion of the diagnostic and therapeutic strategies within an expert multidisciplinary tumour board, is essential for these patients, given its heterogeneity and low frequency. This approach leads to an improvement in patient's outcome, as demonstrated in several studies. The Sarcoma European Latin-American Network (SELNET), aims to improve clinical outcome in sarcoma care, with a special focus in Latin-American countries. These Clinical Practice Guidelines (CPG) have been developed and agreed by a multidisciplinary expert group (including medical and radiation oncologist, surgical oncologist, orthopaedic surgeons, radiologist, pathologist, molecular biologist and representatives of patients advocacy groups) of the SELNET consortium, and are conceived to provide the standard approach to diagnosis, treatment and follow-up of bone sarcoma patients in the Latin-American context

    Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

    Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types

    Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location: Amazonia. Taxon: Angiosperms (Magnoliids; Monocots; Eudicots). Methods: Data for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran\u27s eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny. Results: In the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2^{2} = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2^{2} = 28%). A greater number of lineages were significant indicators of geographic regions than forest types. Main Conclusion: Numerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions
