Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Oficinas culinárias: uma estratégia de educação nutricional sob a perspectiva do PRÓ-SAÚDE.

O Subprojeto 5: Atividades Físicas/Práticas Corporais e Alimentação Saudável: os programas Jogo de Cintura, Doce Desafio e Oficinas Culinárias, inserido no Programa Nacional de Reorientação da Formação Profissional em Saúde, tem como objetivo contribuir para a promoção de modos de viver saudáveis e sustentáveis, com ênfase na alimentação saudável e atividade física. Este estudo traz uma descrição das atividades das Oficinas Culinárias  de alimentação saudável e práticas alimentares. Foram realizadas cinco oficinas, quatro oficinas culinárias e uma de testes sensoriais. As etapas para planejamento das oficinas foram identificação da demanda e definição do tema; pesquisa, seleção das preparações e elaboração das fichas técnicas de preparo (FTP); elaboração do plano da oficina e preparo do material e divulgação; realização da oficina; e, análise dos dados. O público-alvo foi composto de adultos portadores de Diabetes Mellitus ou outras Doenças Crônicas Não Transmissíveis, participantes dos programas Doce Desafio ou Jogo de Cintura para oficinas culinárias e nutricionistas dos Restaurantes Comunitários do Distrito Federal (DF) para oficina de testes sensoriais. Foram aplicados os testes sensoriais  triangular e/ou de aceitação dependendo da oficina. As preparações realizadas apresentaram em geral boa aceitação com exceção daquelas em que houve dificuldades com as instruções da FTP. Os participantes que foram questionados sobre a satisfação com as oficinas, responderam de forma positiva. As Oficinas Culinárias revelam-se como estratégia de educação nutricional no contexto do Pró-Saúde, considerando a comunidade atendida, como campo de prática para ensino e pesquisa e formação dos estudantes dentro dos princípios de atenção primária em saúde

Persea americana Mill.: Evaluation of cytogenotoxicity and phytochemical prospection of leaf extracts

Persea americana Mill., belonging to the family Lauraceae, is noteworthy for the large amount of ethnopharmacological information in its regard, attributing to it many and varied medicinal properties. The tea and alcoholic extracts made from its leaves are used in folk medicine to treat various ailments. This study was designed to analyze the cytogenotoxicity and underlying chemistry of aqueous and hydroalcoholic extracts of avocado leaves, using the Allium cepa and micronucleus tests. The results obtained by applying the experimental models demonstrate that the extracts did not have a genotoxic effect at any of the concentrations analyzed, and even demonstrated a certain protective effect, possibly due to the presence of flavonoids and phenols, both of which are antioxidant substances. However, the extracts did present a cytotoxic effect. There were numerous karyorrhectic cells and those with nuclear alterations related to cell death. At the highest concentrations, it was possible to observe cytoplasmic alterations and binucleated cells. The extracts also caused a significant reduction in the number of cells undergoing division. These effects can be a response to the phytochemical agents present in the extracts. The results suggest that the extracts contain bioactive components that deserve further studies related to cancer therapies

A Transcript Finishing Initiative for Closing Gaps in the Human Transcriptome

We report the results of a transcript finishing initiative, undertaken for the purpose of identifying and characterizing novel human transcripts, in which RT-PCR was used to bridge gaps between paired EST clusters, mapped against the genomic sequence. Each pair of EST clusters selected for experimental validation was designated a transcript finishing unit (TFU). A total of 489 TFUs were selected for validation, and an overall efficiency of 43.1% was achieved. We generated a total of 59,975 bp of transcribed sequences organized into 432 exons, contributing to the definition of the structure of 211 human transcripts. The structure of several transcripts reported here was confirmed during the course of this project, through the generation of their corresponding full-length cDNA sequences. Nevertheless, for 21% of the validated TFUs, a full-length cDNA sequence is not yet available in public databases, and the structure of 69.2% of these TFUs was not correctly predicted by computer programs. The TF strategy provides a significant contribution to the definition of the complete catalog of human genes and transcripts, because it appears to be particularly useful for identification of low abundance transcripts expressed in a restricted set of tissues as well as for the delineation of gene boundaries and alternatively spliced isoforms
