Kérion Celsi: importante diagnóstico diferencial para as dermatofitoses / Kérion Celsi: important differential diagnosis for dermatophytosis

Objetivo: Apresentar os aspectos gerais a respeito da infecção fúngica inflamatória Kérion Celsi. Métodos: Trata-se de uma pesquisa bibliográfica com artigos obtidos nas bases de dados Pubmed, Lilacs, Scielo e Google Scholar, publicados entre os anos de 2008 a 2020. Os Descritores em Ciência da Saúde utilizados foram: “Kérion celsi”, “Tinea capitis” e “Dermatofitose”. Os critérios de inclusão foram artigos de revisão, estudos observacionais e relatos de casos, publicados nos idiomas espanhol, inglês e português, além da relevância e temática compatíveis com o objetivo do estudo. Resultados: O Kérion celsi é uma manifestação rara e grave da Tinea capitis na sua forma inflamatória, que ocorre devido a uma resposta imune exacerbada. É mais observado em crianças devido à alta exposição aos agentes infecciosos e o sistema imunológico mais frágil. A patologia se desenvolve devido a uma hipersensibilidade do tipo IV aos antígenos do fungo. Sua manifestação clínica é caracterizada por um processo inflamatório do tipo foliculite, com área pilosa bem delimitada, dolorosa, com pústulas e abscessos de tendência supurativa. Conclusão: Trata-se de uma patologia com importante impacto na saúde pública. Portanto, o reconhecimento primário e introdução precoce do tratamento são primordiais para uma melhor resolução da doença.

Consumption of sugar-rich food products among Brazilian students:National School Health Survey (PeNSE 2012)

Abstract This study aimed to analyze the consumption of high-sugar foods by Brazilian schoolchildren and to identify associated factors, based on data from the National School Health Survey (PeNSE 2012). Consumption of these foods was classified as: do not consume sweets and soft drinks regularly; consume sweets or soft drinks regularly; and consume sweets and soft drinks regularly. Its association with sociodemographic information, eating habits, and family contexts were investigated via multiple ordinal regressions. Regular consumption of sweets and/or soft drinks was reported by 19.2% and 36.1% of adolescents, respectively, and higher prevalence was associated with female gender, age 14-15 years, higher maternal education, not living with the mother and father, not eating meals with the parents, eating while watching TV, and longer TV time. Nearly one-fifth of adolescents regularly consumed sweets and soft drinks, which was associated with socio-demographic and behavioral factors that should be targeted in order to improve their food consumption

Promoting fruit and vegetable consumption: Methodological protocol of a randomized controlled community trial

This study aimed to develop community educational activities in Brazilian primary health care settings. A randomized controlled community trial was conducted to encourage fruit and vegetable consumption (FV-RCT) in a representative sample of consumers aged 20 years or older in a Brazilian city. The fruit and vegetable consumption was classified according to the transtheoretical model's stages of change, reflecting different degrees of readiness for change. The educational activities were based on the transtheoretical model and a problematizing-dialogic pedagogy, planned by an interdisciplinary team, using information collected in a qualitative pilot study. The actions were conducted over seven months, and baseline data were collected from 1483 participants. The educational strategies included workshops interspersed with motivational messages conveyed via postcard, interactive environment-based activities, and informative material. In the workshops, different techniques were used - conversation circles, image theatre, self-portraits, cooking and art as experience. The applied intervention based on the chosen theories implied in a refinement of the intervention, but, nevertheless, proved to be feasible for large population groups and to the scenario of health services. Thus, this interdisciplinary FV-RCT study represents an effort to advance methodological issues and provide theoretical subsidies for actions.

Occupational status and nutrition profile and health of public municipal employees

Abstract Background: Unhealthy lifestyles occur more often in low-socioeconomic status (SES) groups. The assessment of isolated factors reduces the understanding of the problem instead of clarifying the dynamic interaction of these factors in influencing the health. Objective: To study the relationship between nutrition habits and health, and the coexistence of dietary risk factors, according to the occupational status of public municipal employees. Materials and Methods: An electronic epidemiological survey was conducted from September to December 2009. In total, 5,646 public municipal employees (temporary and permanent) of the municipality (14.7%) answered the questionnaire. Sociodemographic information, health, physical activity, nutritional profile, and working conditions related to eating were investigated. Occupational status was defined by the International Socio-Economic Index. The coexistence of dietary risk factors (low consumption of fruits and vegetables, high consumption of chicken skin and meat fat, and insufficient time to eat at work) were evaluated using Venn diagrams. Results: Arterial hypertension, diabetes mellitus and overweight were more frequently reported in the low occupational status, and positive self-reported health was directly related to the occupational status of participants. Conclusion: Differences in health conditions and in the dietary habits of individuals according to occupational status indicate its relevance in the development of public and institutional policies that aim to promote health and reduce inequalities and the need for greater focus on those with lower occupational status

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
