Abstract The arrival of COVID-19 in Brazil had a marked impact on the health network as well as on the professionals involved, due to the significant number of cases and constantly updated information. In this context, the Cooperative Intelligence Platform for Primary Health Care - Picaps - is set up as a technological platform that assists by systematizing the communication and negotiation processes among actors, with a focus on science and technology. This article sets out to describe the processes of Picaps, which consist of a collaborative system conceived of as a public solution capable of generating innovations in the areas of Science, Technology and Health, in order to tackle COVID-19 in territories with populations in socially vulnerable situations in the Federal District (DF). It integrates data collection and processing, as well as the dissemination of information for its use, both at the governmental and societal levels. Picaps can be seen as a powerful government instrument to help societies across the country, especially those in vulnerable situations, capable of assisting in the use of cooperative intelligence in primary care and health surveillance actions to build innovative solutions such as rapid responses to face health crises in modern times.

Resumo A chegada da COVID-19 ao Brasil gerou grande impacto no sistema de saúde, bem como em seus profissionais, com o elevado número de casos e informações constantemente publicadas. Nesse contexto, criou-se a Plataforma de Inteligência Cooperativa para a Atenção Primária à Saúde (Picaps), uma plataforma tecnológica que ajuda a sistematizar os processos de comunicação e negociação de atores, tendo como foco a ciência e a tecnologia. O presente trabalho tem como objetivo descrever os processos da Picaps, sendo esta constituída por um sistema colaborativo concebido como solução pública capaz de gerar inovações nas áreas de ciência, tecnologia e saúde para o enfrentamento da COVID-19 no Distrito Federal (DF). Nela integram-se processos de coleta e tratamento de dados, além da disseminação de informações visando o seu uso tanto em nível governamental quanto em nível societal. A Picaps pode ser vista como um poderoso instrumento governamental para auxiliar sociedades espalhadas pelo país, sobretudo as que se encontram em situação de vulnerabilidade, com capacidade de nortear o uso da inteligência cooperativa em ações de atenção primária e vigilância em saúde para construção de soluções inovadoras como respostas rápidas para o enfrentamento de crises sanitárias em tempos contemporâneos.

Abstract We investigated the Biogran on bone repair and metabolism at several time-intervals upon grafting into rat tibia artificial defects. The biomaterial was thoroughly characterized in vitro, and its dissolution behavior upon immersion was assessed in simulated body fluid (SBF) solution for 1, 3, 7, 14, and 30 days. Biogran was also assessed by in vitro hydroxyapatite formation in SBF solution, which is a marker for bioactive behavior. In vivo, distal and proximal bone defects were performed in the Wistar rat's right tibia and filled according to the experimental groups: I) negative control, no filling; II) positive control, 10 mg of autogenous bone; and III) 10 mg of Biogran. Animals were euthanized at 1, 2, 3, 4, 7, and 10 weeks. Bone neoformation was analyzed using histomorphometry (proximal defect), and local levels of bone morphogenetic protein 2 (BMP-2) were measured using the ELISA assay (distal defect). In vitro, the Biogran sample showed a fast dissolution rate within the first 7 days, parallel to the formation of the hydroxyapatite layer. In vivo, the sample was progressively resorbed at a higher rate within the first month until it became almost absent at week 10th. The sample presented similar or higher bone neoformation concerning the autogenous bone. BMP-2 levels were sustained in the Biogran group (around 200 pg/mg) and detected until the last experimental time with a significant difference compared with the controls. Results suggest Biogran is a candidate for hard tissue engineering even in highly active bone remodeling sites. timeintervals intervals (SBF 1 3 14 days vivo rats s groups I control filling II III 4 weeks defect, defect , defect) BMP2 BMP (BMP-2 defect. . layer 10th th BMP- around 20 pg/mg pgmg pg controls sites (BMP- (BMP

ABSTRACT Aim: This study aims to identify the organizational climate and culture among nurses working in Immediate Life Support Ambulances (ILSA). Methods: A descriptive, quantitative, and cross-sectional study was conducted with 81 Portuguese nurses working in Immediate Life Support Ambulances at the National Medical Emergency Institute (INEM). The data was analyzed using the Principal Component Analysis (PCA) method, followed by a Varimax rotation, and the models were validated using the Kaiser-Meyer-Olkin test and Bartlett’s test of sphericity. Findings: Factorial analysis yielded four factors, namely: Support (24.5%), Objectives (13.6%), Rules (9.7%), and Innovation (8.01%), associated with organizational climate and culture. Nurses with an undergraduate degree perceived significantly more support than those with higher qualifications. Support also varied according to relationship status, revealing that married nurses had a higher perception than those cohabiting. Conclusion: Organizational climate and culture unequivocally contribute to developing a healthy and safe work environment and are decisive for the quality of nursing care. Aim ILSA. ILSA .

Resumo Antecedentes Encefalites autoimunes (EAIs) são um grupo de doenças inflamatórias caracterizadas pela presença de anticorpos contra antígenos neuronais e gliais, que ocasionam sintomas psiquiátricos subagudos, queixas de memória e distúrbios anormais do movimento. A maioria dos pacientes é jovem, e o atraso no tratamento está associado a pior prognóstico. Objetivo Com o apoio da Academia Brasileira de Neurologia (ABN) e da Sociedade Brasileira de Neurologia Infantil (SBNI), desenvolvemos um consenso sobre o diagnóstico e o tratamento da EAIs no Brasil utilizando a metodologia Delphi. Métodos Um total de 25 especialistas, incluindo neurologistas e neurologistas infantis, foram convidados a participar. Resultados Os especialistas concordaram que os pacientes com critérios de possíveis EAIs devem ser submetidos ao rastreio de anticorpos antineuronais no soro e no líquido cefalorraquidiano (LCR) por meio das técnicas de ensaio baseado em tecidos (tissue-based assay, TBA, em inglês) e ensaio baseado em células (cell-based assay, CBA, em inglês). As crianças também devem ser submetidas ao rastreio de de anticorpo contra a glicoproteína da mielina de oligodendrócitos (anti-myelin oligodendrocyte glycoprotein, anti-MOG, em inglês). O tratamento deve ser iniciado dentro das primeiras 4 semanas dos sintomas, sendo as opções de primeira linha metilprednisolona combinada com imunoglobulina intravenosa (IGIV) ou plasmaférese. O tratamento de segunda linha inclui rituximabe e ciclofosfamida. Bortezomib e tocilizumab são opções de tratamento de terceira linha. A maioria das crises epilépticas nas EAIs são sintomáticas, e os fármacos anticrise podem ser desmamadas após a fase aguda. Em relação à encefalite antirreceptor de N-metil-D-aspartato (anti-N-methyl-D-aspartate receptor, anti-NMDAR, em inglês), os especialistas concordaram que agentes imunossupressores orais não devem ser usados. Os pacientes devem ser avaliados na fase aguda e pós-aguda mediante escalas funcionais e cognitivas, como Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Modified Rankin Scale (mRS), e Clinical Assessment Scale in Autoimmune Encephalitis (CASE).

Abstract Background Autoimmune encephalitis (AIE) is a group of inflammatory diseases characterized by the presence of antibodies against neuronal and glial antigens, leading to subacute psychiatric symptoms, memory complaints, and movement disorders. The patients are predominantly young, and delays in treatment are associated with worse prognosis. Objective With the support of the Brazilian Academy of Neurology (Academia Brasileira de Neurologia, ABN) and the Brazilian Society of Child Neurology (Sociedade Brasileira de Neurologia Infantil, SBNI), a consensus on the diagnosis and treatment of AIE in Brazil was developed using the Delphi method. Methods A total of 25 panelists, including adult and child neurologists, participated in the study. Results The panelists agreed that patients fulfilling criteria for possible AIE should be screened for antineuronal antibodies in the serum and cerebrospinal fluid (CSF) using the tissue-based assay (TBA) and cell-based assay (CBA) techniques. Children should also be screened for anti-myelin oligodendrocyte glucoprotein antibodies (anti-MOG). Treatment should be started within the first 4 weeks of symptoms. The first-line option is methylprednisolone plus intravenous immunoglobulin (IVIG) or plasmapheresis, the second-line includes rituximab and/or cyclophosphamide, while third-line treatment options are bortezomib and tocilizumab. Most seizures in AIE are symptomatic, and antiseizure medications may be weaned after the acute stage. In anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis, the panelists have agreed that oral immunosuppressant agents should not be used. Patients should be evaluated at the acute and postacute stages using functional and cognitive scales, such as the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Modified Rankin Scale (mRS), and the Clinical Assessment Scale in Autoimmune Encephalitis (CASE). Conclusion The present study provides tangible evidence for the effective management of AIE patients within the Brazilian healthcare system.

SUMMARY OBJECTIVE: The aim of this study was to assess the inter-reliability of the Braden scale and its subscales for different patients assisted in the intensive care unit. We hypothesized that the Braden scale has low reliability in different populations. METHODS: This reliability study involved the Braden scale in intensive care unit of a hospital. A total of 200 patients were admitted to the intensive care unit in four different groups: neurological patients, sepsis, elderly, and adults affected by trauma. The Braden scale is a tool composed of six subscales for patient assessment: sensory perception, humidity, activity, mobility, nutrition, and friction. The total score was also calculated. The Braden scale was applied by two different nurses with an interval of 20–30 min between applications. RESULTS: For all populations, kappa values considered unsuitable were observed for most categories of the Braden scale, ranging from 0.06–0.25. Only for the total Braden scale score was moderate reliability identified in all groups evaluated, with intraclass correlation coefficient values ranging from 0.48–0.75. CONCLUSIONS: Braden scale is not a reliable tool to be used in the intensive care unit, and we do not recommend the use of this scale to assess the risk of developing pressure injury.

Resumo Este estudo avaliou o efeito da terapia fotodinâmica (PDT) em canais radiculares infectados com E. faecalis. Vinte e um dentes humanos extraídos foram selecionados, e 18 foram infectados por E. faecalis por 60 dias. As estratégias antimicrobianas testadas foram: G1. Preparo do canal radicular (PCR) com instrumentos rotatórios de NiTi, NaOCl 2,5% e irrigação final com EDTA 17%, seguido de PDT com fotossensibilizador azul de metileno e laser diodo de baixa potência; G2. PCR usando limas de aço inoxidável e os mesmos protocolos de irrigação e PDT do G1; G3. Protocolo de PCR similar que G1 sem PDT; G4. Somente irrigação com NaOCl 2,5%; G5. Protocolo similar ao G1, sem PCR; G6. Controle negativo; G7. Controle positivo. Amostras para exames microbiológicos foram coletadas inicialmente (S1), após PCR (S2) e após PDT (S3). Na sequência, as raízes foram seccionadas e preparadas para análise em microscopia eletrônica de varredura (MEV). O crescimento bacteriano foi analisado de acordo com a turbidez do meio de cultura seguida pela densidade óptica espectrofotométrica (nm). O efeito da PDT na estrutura dentinária foi avaliado em aumentos de 1.600X e 5.000X, e descrito qualitativamente. O teste de Wilcoxon foi utilizado para as comparações dos mesmos espécimes e o teste de Mann-Whitney para as comparações entre os grupos ((=5%). Bactérias foram encontradas em todos os grupos experimentais, e em todas as coletas microbiológicas (S1, S2 e S3). A densidade óptica dos meios de cultura foi menor em S2 do que em S1 de G1, 2, 3 e 4 (p>0,05). Após a PDT (S3) em G1 e 2, houve redução adicional na densidade óptica do meio de cultura de 90,0% e 92,0%, respectivamente (p>0,05). No Grupo 5, a análise dos meios de cultura em S2 revelou um aumento de 3,2% na densidade óptica em comparação com S1(p>0,05). Nas imagens de MEV do G1, 2 e 5 foram evidenciadas dentina com áreas de fusão e recristalização. O PDT utilizado após preparo do canal radicular com sistema rotatório ou manual, associado ao NaOCl 2,5%, não foi capaz de eliminar completamente o E. faecalis em biofilme maduro presente no canal radicular.

Abstract This study evaluated the effect of photodynamic therapy (PDT) on infected root canals. Twenty-one human teeth were selected, and 18 were infected by E. faecalis for 60 days. The antimicrobial strategies tested were: G1. Root canal preparation (RCP) using Niquel-Titanium (NiTi) rotary instruments, 2.5% NaOCl, and final irrigation with 17% EDTA, followed by PDT with methylene blue photosensitizer and laser diode low power; G2. RCP using stainless steel files and the same irrigation and PDT protocols as G1; G3. Same RCP protocol as G1 without PDT; G4. Only irrigation with 2.5% NaOCl; G5. Same PDT protocol as G1 without RCP; G6. Negative control; G7. Positive control. Samples for microbiological tests were collected initially (S1), after RCP (S2), and after PDT (S3). Subsequently, the roots were sectioned and prepared for Scanning Electron Microscopy (SEM) analysis. Bacterial growth was analyzed according to the turbidity of the culture medium, followed by spectrophotometric optical density (nm). The effect of PDT on the dentinal structure was evaluated at magnifications 1,600X and 5,000X and described qualitatively. The Wilcoxon test was used for the comparisons from the same specimens, and the Mann-Whitney test was used to compare groups ((=5%). Bacteria were found in all experimental groups’ microbiological samples (S1, S2 and S3). The optical density of culture media was lower in S2 than in S1 of G1, 2, 3, and 4 (p> 0.05). After PDT (S3) in G1 and 2, there was an additional reduction in optical density of the culture medium, respectively (p>0.05). In Group 5, the analysis of culture media at S2 revealed an increase in optical density compared to S1(p>0.05). In SEM images of G1, 2, and 5, dentin with melting and recrystallization areas were evidenced. After preparation of the root canal with the rotary system or manually associated with 2.5% NaOCl, PDT was not able to completely eliminate E. faecalis present in the root canal.

Resumo A Curcuma longa L., planta conhecida popularmente como açafrão, tem sido amplamente estudada por suas diversas propriedades terapêuticas, incluindo a ação antineoplásica. O extrato etanólico da planta contém diversos compostos fenólicos, com destaque para a curcumina. O osteossarcoma é um tumor ósseo predominante em cães e humanos, caracterizado por apresentar alto potencial metastático e prognóstico desfavorável. Procurou-se investigar os efeitos de diferentes concentrações de curcumina do extrato etanólico de açafrão sobre células de osteossarcoma canino de cultura estabelecida. As células foram cultivadas e submetidas ao tratamento com extrato com diferentes concentrações de curcumina (0, 10 μM, 20 μM, 50 μM, 100 μM e 1000 μM) e tempos de exposição (24h, 48h e 72h) pelo EEA. Inicialmente, foram realizados: técnica de redução do tetrazólio (MTT) e cálculo da IC50. Posteriormente, após o tratamento com o extrato, realizou-se o ensaio de imunocitoquímica para verificar a expressão de p53 mutada e estudar o potencial proliferativo das células malignas; Bcl-2, com intuito de averiguar o estímulo de via antiapoptótica; e o marcador Ki-67, que sinaliza aumento no grau de malignidade. O extrato promoveu proliferação de células de osteossarcoma canino, com incremento de até 3819,74% na concentração de 50μM de curcumina. O composto também alterou a expressão das proteínas p53 mutante e Ki-67 significativamente, mas não alterou a expressão de Bcl-2, mostrando que não induziu a via antiapoptótica mediada por esta. Estes resultados demonstram que o extrato etanólico do açafrão apresenta potencial proliferativo sobre células de osteossarcoma canino, sugerindo a necessidade de conscientização e conhecimento dos reais efeitos de determinados compostos naturais, considerados seguros ao serem utilizados como tratamento de diversas enfermidades.

Osteosarcoma is a predominant bone tumor in dogs and humans, characterized by high metastatic potential and an unfavorable prognosis. The aim of this study was to investigate the effects of turmeric ethanol extract on canine osteosarcoma cells from established culture. The cells were cultured and treated with different curcumin concentrations (0, 10 μM, 20 μM, 50 μM, 100 μM, and 1000 μM) and exposure times (24h, 48h, and 72h). We first performed tetrazolium reduction technique (MTT) assay and calculated IC50. An immunocytochemistry assay was performed after extract treatment to verify the expression of mutated p53 and therefore study the proliferative potential of malignant cells; Bcl-2 and Ki-67 were used to assess apoptosis and the degree of malignancy, respectively. The extract enhanced the proliferation of canine osteosarcoma cells, reaching 3,819.74% at 50 μM of curcumin. The extract also significantly altered the expression of mutated p53 and Ki-67 proteins but not that of Bcl-2, suggesting that it did not induce this antiapoptotic pathway. Overall, these results are prerequisite to better understanding how natural compounds such as turmeric ethanolic extract affect cell proliferation and could be used to treat various diseases.

RESUMO O artigo examina as relações entre os sujeitos da aprendizagem, tanto o estudante quanto o/a professor/a, e a mobilização do conceito de democracia na Base Nacional Comum Curricular (BNCC) correspondente à etapa do Ensino Médio, com destaque para a área de Ciências Humanas e Sociais Aplicadas na versão final de 2018. A partir das circunstâncias históricas de produção dessa versão final da BNCC e da delimitação teórica dos dilemas que afetam as subjetividades contemporâneas, é analisado o modo pelo qual o conceito de democracia figura no texto da base curricular mencionada. Constata-se que a democracia é situada como regulador das aspirações ético-políticas de estudantes, sob o viés, no entanto, de horizonte de estabilidade política, desprovida de historicidade, esvaziando assim a agência e o enfrentamento da crise contemporânea pelos sujeitos da aprendizagem.

ABSTRACT The article examines the relationships between the subjects of learning, both the student and the teacher, and the mobilization of the concept of democracy, in the National Common Curricular Base, stage of High School, highlighting the area of Applied Human and Social Sciences, final version of 2018. The way in which the concept of democracy appears in the current curriculum base text is analyzed, based on the historical circumstances of the production of this final version of this curriculum and, also, based on the theoretical delimitation of the dilemmas that affect contemporary subjectivities. The main conclusion is that democracy is situated as a regulator of the ethical-political aspirations of students, under the bias, however, of a horizon of political stability, devoid of historicity, thus emptying the agency and the confrontation of the contemporary crisis by the subjects of learning.

Abstract: This study measured the thickness of cementum/dentin in the danger zone of the mandibular molars after root canal preparation using novel cone-beam computed tomography (CBCT) software. Eighty-four teeth were distributed into four groups: ProTaper Next, BioRace, Reciproc Blue, and WaveOne Gold. E-Vol DX® CBCT software was used to measure initial and final remaining cementum-dentin thicknesses after root canal preparation of the mesial root of mandibular molars at 1 and 3 mm from the furcation. The Kolmogorov-Smirnov test was used to test variable symmetry. The variables were described as mean and standard deviations, compared among the groups using analysis of variance (ANOVA), and within the groups using the Student t test. A generalized estimating equation model was used to compare the variation before and after root canal preparation. The level of significance was set at 5%. Differences between mean initial and final thicknesses of the mesiobuccal (MB) and mesiolingual (ML) canals were not statistically significant. The mean initial thickness was 3 mm (0.900 mm ± 0.191), considering that a mean lower than 1 mm (1.035 mm ± 0.184) indicates the danger zone. Although cementum/dentin is thinner at 3 mm from the furcation (0.715±0.186) after root canal preparation, the greatest amount of dentin removed was found at 1 mm (0.734 ± 0.191). The cementum-dentin remaining after preparation was thicker than 0.715 mm in root canals prepared using #35 (WaveOne Gold®) and #40 (ProTaper Next®, BioRace® and Reciproc Blue®) instruments. This confirms the safety of canal preparation in the danger zone using these systems.

Resumo Este estudo teve como objetivo comparar os valores da pressão intraocular (PIO) por diferentes tonômetros e avaliadores (veterinário oftalmologista especialista e veterinário não especialista). Para isso, foram utilizados 30 coelhos, em todos (n = 60 olhos), a PIO foi medida inicialmente com um tonômetro de rebote (model TD - 8000 portable, Apramed Indústria e Comércio de Equipamentos Médicos Ltda) e, posteriormente, com um tonômetro de aplanação (portable model Tono-Pen AviaTM®, Reichert Technologies®, USA). Com os dois aparelhos, as medidas em mmHg foram realizadas na região central das córneas, sempre no mesmo período, por um profissional oftalmologista veterinário (especialista) e um profissional veterinário (não especialista). Os dados foram comparados estatisticamente por meio do teste de análise de variância simples. Com o tonômetro de rebote, a PIO variou de 7 a 14 mmHg quando medida por ambos os avaliadores; enquanto com o tonômetro de aplanação, de 9 a 15 mmHg pelo especilista e de 8 a 16 mmHg pelo não especialista. Nos olhos direitos, a PIO medida pelo tonômetro de aplanação pelo avaliador não experiente foi estatisticamente inferior aos valores do especialista; ainda, os resultados dos dois avaliadores foram maiores nestes mesmos olhos quando comparados com os do tonômetro de rebote. Nos olhos esquerdos, a PIO medida pelo tonômetro de aplanação pelo avaliador não experiente foi estatisticamente superior aos valores do especialista com o tonômetro de rebote. Assim, foi possível inferir que, independente da experiência na área, o tonômetro de aplanação indicou maiores valores médios de PIO em ambos os olhos e, em relação aos avaliadores, as médias das medidas realizadas pelos especialistas foram maiores em relação ao não especialista.

Abstract This study aimed to compare values of intraocular pressure (IOP) by different tonometers and evaluators (veterinary ophthalmologist specialist and veterinary not a specialist). For this, 30 rabbits were used, and in all (n = 60 eyes), the IOP was initially measured with a rebound tonometer (model TD - 8000 portable, Apramed Indústria e Comércio de Equipamentos Médicos Ltda) and, subsequently, with an applanation tonometer (portable model Tono-Pen AviaTM®, Reichert Technologies®, USA). With the two devices, the measurements in mmHg were performed in the central region of the corneas, always performed in the same period, by a professional veterinary ophthalmologist (specialist) and a professional veterinary (not a specialist). Data were statistically compared using the simple analysis of variance test. With the rebound tonometer, IOP ranged from 7 to 14 mmHg when measured by both evaluators; while with the applanation tonometer, from 9 to 15 mmHg by the specialist and from 8 to 16 mmHg by the non-specialist. In the right eyes, the IOP measured by the applanation tonometer by the non-experienced evaluator was statistically lower than the specialist's values; yet, the results of the two evaluators were higher in these same eyes when compared with those of the rebound tonometer. In the left eyes, the IOP measured by the applanation tonometer by the non-experienced evaluator was statistically higher than the specialist's values with the rebound tonometer. Thus, it was possible to infer that, regardless of experience in the area, the applanation tonometer indicated higher mean values of IOP in both eyes and, about the evaluators, the means of the measurements performed by the specialist were higher compared to the non-professional specialist.

Abstract INTRODUCTION: This epidemiological household survey aimed to estimate the prevalence of the current and past SARS-CoV-2 infections in Ribeirão Preto, a municipality of southeast Brazil. METHODS: The survey was conducted in two phases using a clustered sampling scheme. The first phase spanned May 1-3 and involved 709 participants. The second phase spanned June 11-14, 2020, and involved 646 participants. RESULTS: During the first phase, RT-PCR performed on nasopharyngeal swabs was positive at 0.14%. The serological tests were positive in 1.27% of the patients during the first phase and 2.79% during the second phase. People living in households with more than five members had a prevalence of 10.83% (95%CI: 1.58-74.27) higher than those living alone or with someone other. Considering the proportion of the positive serological test results with sex and age adjustments, approximately 2.37% (95%CI: 1.32-3.42) of the population had been cumulatively infected by mid-June 2020, which is equivalent to 16,670 people (95%CI: 9,267-24,074). Considering that 68 deaths from the disease in the residents of the city had been confirmed as at the date of the second phase of the survey, the infection fatality rate was estimated to be 0.41% (95%CI: 0.28-0.73). Our results suggest that approximately 88% of the cases of SARS-CoV-2 infection at the time of the survey were not reported to the local epidemiological surveillance service. CONCLUSIONS: The findings of this study provide in-depth knowledge of the COVID-19 pandemic in Brazil and are helpful for the preventive and decision-making policies of public managers.

Abstract Objective To identify nursing diagnoses of the NANDA-I Taxonomy in institutionalized older adults. Method A descriptive study, conducted with 116 older adults from a long-term institution, carried out based on the identification of nursing diagnoses of the NANDA-I Taxonomy in an instrument based on the theoretical model of Basic Human Needs and validation by experts with support in Risner's diagnosis reasoning. Results 1,555 nursing diagnosis titles were indicated for the 116 older adults, with a mean of 13.4 diagnoses per individual. After excluding repetitions, 39 different diagnosis titles were obtained. Among them, 26 (66.7%) are titles of real diagnoses, 13 (33.3%) are titles of risk diagnoses and are classified in 8 of the 13 domains of the NANDA-I taxonomy. The most frequent nursing diagnoses were the following: risk for falls (94.8%); frail elderly syndrome (91.3%), and dysfunctional family processes (90.5%). Conclusion and implications for the practice The profile of the nursing diagnoses identified can contribute to the increase of sensitive indicators to the nursing practice, with the planning and implementation of care measures directed to the real needs of institutionalized older adults, impacting on autonomy, independence and, consequently, on quality of life.

Abstract: En | Text: En | PDF: En

Abstract wastewater treatment (WT) is of major importance on modern cities, removing wastewater pollutants resultant from anthropogenic activities. The unique abilities of microbes to degrade organic matter, remove nutrients and transform toxic compounds into harmless products make them essential players in waste treatment. The microbial diversity determines the metabolic pathways that may occur in WT and quality of treated wastewater. Therefore, understanding WT microbial community structure, distribution, and metabolic functioning is essential for development and optimization of efficient microbial engineering systems. Since cultivation methods can only detect a small fraction of the microbial diversity, the use of culture-independent molecular methods has circumvented this issue, allowing unprecedented access to genes and genomes used for microbial composition and function evaluation. Traditional approaches like RAPD, DGGE, ARDRA, RISA, SSCP, T-RFLP, and FISH and modern approaches like microarray, qPCR, and metagenomics are essential techniques for identifying and depicting the total microbial community structure and their interaction with environmental and biotic factors. Thus, this review describes traditional and state of the art molecular techniques which provide insights into phylogenetic and functional activities of microbial assemblages in a WT system.
