Abstract This paper presents the strategies and initial implementations of a data culture conversion process at a company in the electricity sector. Solutions are being developed within the scope of the construction management macro-process, which involves multiple sectors of the company, as well as external agents. The strategy is based on implementing Proofs of Concept as tools for converting the data culture within the company and, at the same time, supporting the essential activities of construction management. The proofs of concept aligned with the change in data culture have two components: technology and people. The first consists mainly of intelligent automation and process optimization. The second component involves sensitization, training and developing solutions together with the company's employees. The results involve a reduction in workload since some activities have been partially or totally transferred to the software. Greater assertiveness in estimating numerical data, such as prices and budgets. Increased reliability by reducing human intervention and complex calculations. Greater controllability by monitoring multiple activities and sectors, simplifying management. Finally, the integration of technology and people has shown significant advances in organizational culture, enabling employees to have a greater understanding of advanced tools and methods and to be able to identify opportunities and share solutions within the company. sector macroprocess, macroprocess macro process, macro-process agents time components optimization sensitization companys s software budgets calculations Finally

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Abstract Physicians and dentists usually make clinical decisions and recommendations without a clear understanding of the meaning of the numbers regarding the accuracy of diagnostic tests and the efficacy of treatments. This critical review aimed to identify problems in the communication of diagnostic test accuracy and treatment benefits and to suggest strategies to improve risk communication in these contexts. Most clinical decisions are taken under uncertainty. Health professionals cannot predict the outcome in one individual patient. This uncertainty invites these professionals to make decisions based on heuristics, which gives rise to several cognitive biases. Cognitive biases are automatic and unconscious, so how is it possible to mitigate their undesirable effects on risk interpretation in the context of clinical practice? Some forms of risk communication reinforce cognitive bias, while others weaken them. Maybe one of the most difficult obstacles to overcome is the difficulty to think with numbers. This difficulty probably arises from a mismatch of ancestral adaptations of the brain having to deal with modern environments, which are quite different from the ancestral ones. There are two quite common, but bad, forms of risk communication: the conditional probability and the relative risk reduction or efficacy. People, including physicians and dentists, are confused with this kind of information. The main methods discovered so far to facilitate a clearer understanding are to emphasize the base rates of the events and to use absolute numbers, that is to use natural frequencies, instead of percentages and conditional probabilities.

CONTEXTO: Este estudo procurou estabelecer, sob o ponto de vista descritivo, o nível de cognição e variáveis sociodemográficas associadas em mulheres da sétima à nona década, em dois serviços públicos, na cidade de São Luís (MA). OBJETIVOS: Estudar o nível de cognição pelo Miniexame do Estado Mental (MMSE) e variáveis sociodemográficas associadas em mulheres da sétima à nona década, em dois serviços públicos, na cidade de São Luís (MA). MÉTODOS: Durante quatro meses um questionário com as variáveis sociodemográficas e o Miniexame do Estado Mental (MMSE) foram aplicados em pacientes ambulatoriais. As voluntárias foram avaliadas nos ambulatórios de Neurologia do Hospital Universitário Presidente Dutra e do Hospital Estadual Carlos Macieira. RESULTADOS: Oitenta pacientes foram avaliadas - 31,2% foram classificadas com transtorno cognitivo ao MEEM; 71,4% destas tinham entre 81 e 85 anos. Transtorno cognitivo estava presente em 65% das pacientes com nível educacional inferior a sete anos. Em relação ao nível de renda e cognição, foi observado que 30,4% das pacientes que apresentavam nível de renda menor que um a dois salários mínimos eram classificadas com transtorno cognitivo. Das 33 voluntárias que tinham cuidador direto, 57,6% apresentavam transtorno cognitivo. CONCLUSÕES: O estudo torna-se de relevância, pois permite se atentar para o problema na região e serve de estímulo para estudos metodológicos mais complexos, visando promover a saúde pública mental do idoso.

BACKGROUND: This study aims to establish a descriptive study about the cognition level and correlated socio-demographic variables, of the female sex, from the seventh to the nineth decade in two public services in the city of São Luís (MA). OBJECTIVES: Study about the cognition level with Mini Mental State Examination (MMSE) and correlated socio-demographic variables, of the female sex, from the seventh to the nineth decade in two public services in the city of São Luís (MA). METHODS: During four months, a questionnaire with socio-demographic variables and the Mini Mental State Examination (MMSE) were applied in the patients attending. The voluntaries were evaluated in the Neurology clinics of the University Hospitals President Dutra and Statue Carlos Macieira. RESULTS: Eighty patients were evaluated - 31,2% were classified by MEEM with the cognitive troubles; 71,4% of these were between 81 and 85 years old. Cognitive disorder was present in 65% of the patients who had less education up to seven years. As for income and cognition level, it was observed that 30,4% of the volunteers who presented an income level lower than one to two minimum wage were classified with cognitive disturbances. From the 33 volunteers that had direct care, 57,6% presented cognitive disturbances. DISCUSSION: The study becomes relevant, because it allows to attempt to the problem in that region and it serves as a stimulus for the more complex methodological studies seeking to promote the elderly public mental health.

O objetivo dessa pesquisa foi avaliar a atividade antimicrobiana de duas pastas experimentais, contendo própolis associada a hidróxido de cálcio, contra culturas polimicrobianas coletadas de 16 molares decíduos necrosados e com fístulas extraídos de crianças entre 4 e 6 anos de idade de ambos os sexos. A técnica de difusão em ágar foi utilizada para determinar a atividade antimicrobiana das seguintes pastas: (1) 11,0% extrato etanólico de própolis + hidróxido de cálcio e (2) 11,0% extrato de própolis sem álcool + hidróxido de cálcio. A associação de hidróxido de cálcio com propilenoglicol foi utilizada como o grupo de controle positivo (CHP). Testes estatísticos de Friedman and Wilcoxon foram empregados para comparar dados do crescimento das zonas de inibição (p<0,05). Pasta 1 e Pasta 2 apresentaram zonas de inibição maiores contra os microrganismos coletados dos canais radiculares do que CHP (p=0,021 e 0,003 respectivamente). A Pasta 2 mostrou zonas de inibição um pouco mais largas que a Pasta 1 (p=0,053). A associação entre própolis e hidróxido de cálcio foi efetiva no controle de infecções dentárias in vitro.

The purpose of this study was to evaluate the antimicrobial activity of two experimental pastes containing propolis extract associated with calcium hydroxide against polymicrobial cultures collected from 16 necrotic and fistulae root canals in primary molars of 4-8-year-old children of both sexes. The agar-well diffusion technique was used to determine the antimicrobial activity of the following pastes: 11.0% ethanolic extract of propolis (EEP) + calcium hydroxide; and 11.0% extract of propolis without ethanol (EP) + calcium hydroxide. EEP, EP and the association of calcium hydroxide and propylene glycol (CHP) was used as the positive control groups, and propylene glycol was used as a negative control group. Friedman and Wilcoxon tests were used to compare the data from the microbial growth inhibition zones (p<0.05). Paste 1 and Paste 2 showed larger growth inhibition zones against microorganisms from root canal samples than CHP (p=0.021 and 0.003, respectively). Paste 2 tended to have larger growth inhibition zones than Paste 1 (p=0.053). The association between propolis and calcium hydroxide was effective in controlling dental infections in vitro.

OBJETIVO: Reduzir lista de alimentos de um questionário de freqüência alimentar semiquantitativo através de diversas estratégias metodológicas, mantendo-se a capacidade de análise do consumo de energia, proteínas, glicídios, lipídeos, cálcio e ferro. MÉTODOS: Utilizou-se um questionário de freqüência semiquantitativo com 80 itens alimentares respondidos por 224 meninas (12-19 anos). Reduziu-se a lista por regressão linear múltipla, freqüência de consumo e composição nutricional dos alimentos. Analisou-se por teste t de Student, sensibilidade de distribuição das adolescentes por quartis de consumo, coeficiente Kappa e modelos de regressão. RESULTADOS: Os alimentos incluídos apresentaram coeficiente de regressão positivo, com valor de F significativo (P<0,001). As variâncias totais dos modelos foram superiores a 0,87, com alguns alimentos não apresentando plausibilidade nos modelos. Selecionaram-se 32 alimentos dos modelos e 37 dentre os freqüentemente consumidos. Os dois critérios apresentaram alguns alimentos distintos; quando os mesmos foram integrados, obtiveram-se 40 alimentos para lista reduzida. As médias de consumo não diferiram entre a lista integral e a reduzida. As análises de sensibilidade variaram entre 85% e 100%. O grau de concordância foi significativo para todos os fatores dietéticos. Os modelos de regressão com a lista reduzida mantiveram variâncias totais acima de 0,85 e alimentos semelhantes aos anteriores. CONCLUSÃO: Os critérios estabelecidos foram apropriados para reduzir a lista de 80 alimentos em 40, mantendo-se a capacidade de predição e de avaliação do consumo alimentar dos componentes investigados para o grupo populacional utilizado.

OBJECTIVE: To reduce the food list of a semi-quantitative food frequency questionnaire, through several methodological strategies, maintaining the ability to assess energy, proteins, glycids, lipids, calcium, and iron consumption. METHODS: A semi-quantitative 80-item food frequency questionnaire, answered by 224 female adolescents (aged 12-19 years) was used. The list was reduced through multiple linear regressions, frequency of consumption and food nutritional composition. It was assessed through Student's t-test, sensitivity of adolescents' distribution according to consumption quartiles, Kappa coefficient and regression models. RESULTS: Food included in the analysis showed a positive regression coefficient, with a significant F value (P<0.001). The models' total variances were over 0.87, and some food types did not show plausible models. Thirty-two food types were selected among the models, and 37 among the most commonly consumed ones. Both criteria included some different foods and, when these were merged, 40 food types formed the abridged list. Consumption averages did not vary between the complete list and the reduced one. Sensitivity analyses ranged from 85% to 100%. The agreement level was significant for all diet factors. Regression models in the reduced list kept total variances over 0.85 and similar food types as compared to the previous ones. CONCLUSION: The established criteria were appropriate to reduce the food list from 80 to 41 items, keeping the predictive ability and food intake assessment of the components investigated in this population group.

Segundo o paradigma atual de promoção de saúde, a atenção odontológica deve se iniciar ainda nos primeiros meses de vida ou então anteriormente ao nascimento, já que hábitos alimentares e de higiene bucal se estabelecem muito cedo. Avaliou-se o grau de conhecimento e as atitudes das mães com relação à saúde bucal do bebê, após as mesmas terem recebido orientações no período neonatal (projeto "Odontopediatria no alojamento conjunto"/ UFG). Quarenta e seis mães com idades de 15 a 38 anos foram questionadas a respeito das orientações recebidas, bem como seu comportamento em relação às mesmas. Dividiu-se a casuística em dois grupos, A (n=25) e B (n=21), de acordo com o tempo decorrido após a implementação do projeto, ou seja, menor ou igual a três meses e maior que três meses, respectivamente. Frente às orientações recebidas (transmissibilidade da cárie dentária, hábitos alimentares, desenvolvimento das arcadas e higiene bucal), a análise de variância não mostrou diferenças estatisticamente significantes entre os dois grupos (p > 0,05), no que diz respeito ao conhecimento e atitudes das mães. As orientações de higiene bucal do bebê, de aleitamento materno exclusivo até seis meses e a restrição na ingestão de açúcar foram as mais lembradas pelas mães. Recomendações referentes à contribuição ao bom desenvolvimento das arcadas e às precauções quanto ao uso de mamadeiras foram menos recordadas. Considerando a saúde bucal do lactente, seria aconselhável que cuidadores sejam orientados nos períodos pré- e neonatal, sendo que a segunda consulta odontológica pós-nascimento deve idealmente ocorrer por volta do quarto mês de vida da criança.

According to the current paradigm for promoting health, dental care should be a consideration from the first months of life, or even before birth. The aim of this paper is to evaluate mothers' knowledge of and attitude toward their babies' oral health after receiving guidance during the neonatal period. Forty-six mothers were contacted and asked about the advice they had received and how they felt about the information provided. The mothers recruited for the study were divided into two groups, A (n=25) and B (n=21), according to the time elapsed since their participation in the project, that is, less than or equal to three months and more than three months, respectively. A Wilcoxom rank sum test did not show any statistically significant difference between the two groups (p>0.05). Guidance on the baby's oral hygiene, breastfeeding the baby exclusively until the sixth month, as well as the restrictions imposed on sugar intake were what the mothers remembered most. Recommendations concerning good arch development and the use of bottles were what mothers remembered least. Regarding infant oral health, it would be advisable to schedule prenatal and neonatal visits, with the second post-natal consultation no later than four months after childbirth.
