Prevalencia de lesiones por fricción en pacientes hospitalizados con cancer

Esse estudo objetivou identificar a prevalência de lesões por fricção (LF) em pacientes hospitalizados com câncer e avaliar os fatores demográficos e clínicos associados ao seu desenvolvimento. Estudo epidemiológico, de corte transversal, realizado no Instituto do Câncer do Estado de São Paulo Octavio Frias de Oliveira. Todos os pacientes adultos, internados entre 10 e 18 de abril de 2010, foram avaliados por meio de entrevista e exame físico. Utilizou-se o teste Qui-Quadrado para comparação das variáveis demográficas e clínicas entre pacientes com e sem LF. Foram avaliados 157 pacientes: cinco apresentaram nove LF, acarretando prevalência de 3,3%. Quanto às variáveis demográficas, houve diferença estatisticamente significativa somente para o número de filhos (p=0,027). Clinicamente, pacientes com LF apresentaram menores escores na escala de Karnofsky (p=0,031) e na Escala de Braden (p=0,026), além de comportamento pouco colaborativo (p=0,042). Esse estudo contribui para um melhor conhecimento acerca das LF em pacientes com câncer

Estudio epidemiológico fue desarrollado en el Instituto de Cáncer del Estado de São Paulo Octavio Frias de Oliveira. Los pacientes adultos ingresados del 10 al 18 de abril de 2010 fueron evaluados por medio de entrevista y examen físico. El teste de Qui-cuadrado fue usado para comparar las variables demográficas y clínicas entre los grupos de pacientes con y sin LF. Cinco entre los 157 pacientes evaluados presentaron nueve LF, con prevalencia de 3,3%. Solamente el número de hijos presentó diferencia estadística significativa (p=0,027) cuanto a variables demográficas. Clínicamente, pacientes con LF presentaron puntuaciones más bajas en las escalas de Karnofsky (p=0,031) y Braden (p=0,026) y menos comportamientos colaborativos (p=0,042). El estudio contribuye para el mejor conocimiento a cerca de LF en pacientes con cáncer.This study aimed to analyze the prevalence of skin tears (ST) among hospitalized oncology patients and associated demographic and clinical variables. This is an epidemiological cross-sectional study type, performed at Octavio Frias de Oliveira State of São Paulo Cancer Institute. All adult patients hospitalized from April 10th to 18th 2010 were evaluated by interview and physical examination. Chi-square test was used to compare demographic and clinical variables between patients with and without ST. Five patients among 157 had nine skin tears, resulting in a prevalence of 3.3%. Among demographic variables, only number of children showed statistically significant difference (p=0.027) between groups. Clinically, patients with ST had lower Karnofsky scores (p=0.031), lower scores at Braden Scale (p=0.026) and less collaborative behaviors (p=0.042) when compared to patients with no lesions. This study contributes to a better knowledge of ST in oncology patients

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
