Evaluation of sound pressure levels in a pediatric intensive care unit

This study objectives were to measure the sound pressure levels found in the pediatric intensive care unit in a federal institution of Rio de Janeiro; to verify differences in noise levels during the morning and afternoon; to confront the sound pressure levels found against acceptable levels according to national and international noise organizations; to count the quantity of alarms triggered by each type of medical care equipment selected (multiparameter monitor, mechanical ventilator and infusion pump); to verify the relevance in the scientific world about pediatric intensive care unit noise through bibliometrics and to address the trinomial care technology - noise - implications on care. It’s an observational, exploratory, quantitative study, organized in three steps: Parameter collection and decibel meter calibration - data were based on the study by Salú, et al (2015) ; Data collection: 40 hours of discontinued observation (8am to 16pm) on different days for a period two months using two decibel meters; Data processing: An Excel spreadsheet was created for the database and data analysis was performed with the help of Microsoft Office Excel 2010 and Program R, organized into graphs and tables. 61% of the alarms corresponded to the mechanical ventilator; Bed E had the lowest standard deviation (SD = 2.945) and the highest median (69.5dBA). Even by removing the E bed from the analysis, there is a significant difference (p <0.001) between sound pressure levels. The median of the afternoon (28.2dBA); and morning (26.1dBA). Mechanical fan and monitor generated higher sounds; the pediatric intensive care unit has considerably exceeded that recommended by national and international noise organizations; afternoon generated higher sounds than morning. Keywords: Noise Meters; Noise; Intensive care; Pediatric

Qualidade microbiológica e caracterização da resistência antimicrobiana de bactérias isoladas de queijos Coalho comercializados em Vitória da Conquista-Bahia

Neste estudo foram determinadas a qualidade higiênico-sanitária, a prevalência e a resistência antimicrobiana de patógenos isolados de 24 amostras de queijo Coalho comercializados em duas feiras livres do município de Vitória da Conquista, Bahia. Foram realizadas análises físico-químicas e microbiológicas através de métodos convencionais interpretados conforme legislação vigente. Identificamos que 75% das amostras eram comercializadas em temperatura inadequada e que 100% apresentaram contagem para coliformes totais acima do limite aceitável.  Staphylococcus coagulase positiva e Escherichia coli foram isolados em 87,5% e 62,5% das amostras, respectivamente. Não foi detectada a presença de Listeria monocytogenes e Salmonella sp. Identificamos 51,1% de resistência a pelo menos um dos sete antimicrobianos testados para Staphylococcus coagulase positiva e 44,4% para pelo menos um dos 11 avaliados para E.coli. As análises realizadas evidenciaram uma precariedade higiênico-sanitária na produção e comercialização de queijo coalho nas feiras livres de Vitória da Conquista. Torna-se também uma preocupação, a presença de bactérias resistentes aos antimicrobianos nestes queijos. Deste modo, ressaltamos a importância do controle de qualidade na produção e comercialização destes produtos, assim como a necessidade das ações da vigilância sanitária para orientação aos manipuladores e produtores de queijo

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
