ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.
RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização, baseada em evidências científicas, sobre cada tópico relacionado ao tratamento sistêmico e a apresentar os dados e recomendações resumidas durante a reunião. Todos os painelistas se reuniram para discutir os tópicos e elaborar as recomendações atualizadas. O presente documento é a versão final do manuscrito revisado, contendo as recomendações da SBH, e seu objetivo é auxiliar os profissionais de saúde, formuladores de políticas e planejadores no Brasil e na América Latina na tomada de decisões sobre o tratamento sistêmico de pacientes com CHC.

Abstract The canine filarial parasite Dirofilaria immitis has not been reported in Brazil´s Amazonas state capital, Manaus, for over a century. Here, we report one imported and 27 autochthonous D. immitis infections from a microfilarial survey of 766 domestic dog blood samples collected between 2017 and 2021 in Manaus. An Overall prevalence estimate of 15.44% (23/149) was calculated from our two rural collection sites; a prevalence of 1.22% (4/328) was estimated at our periurban collection site, and an overall prevalence of 0.35% (1/289) was calculated from our two urban clinic collections. Our data suggest that in the urban areas of Manaus, where the parasites are very likely vectored by the same species of mosquito that historically vectored Wuchereria bancrofti (Culex quinquefasciatus), prevalence levels are very low and possibly maintained by an influx from rural areas where sylvatic reservoirs and/or more favorable vector transmission dynamics maintain high prevalences.
Resumo O parasita filarial canino, Dirofilaria immitis, causa doença zoonótica, mas não tem sido registrado em Manaus, capital do estado do Amazonas, há mais de um século. Neste trabalho, foi relatado uma infecção por D. immitis alóctone e 27 autóctones de um levantamento de microfilárias em 766 amostras de sangue em cães domésticos, coletados entre 2017 e 2021 em Manaus. A prevalência de 15,44% (23/149) foi estabelecida em áreas rurais, 1,22% (4/328) para áreas periurbanas e de 0,35% (1/289) para duas clínicas veterinárias localizadas na zona urbana da cidade. Estes dados sugerem, portanto, que nas áreas urbanas de Manaus, nas quais o parasita é provavelmente vetorizado pela mesma espécie de mosquito que, historicamente, transmitiu Wuchereria bancrofti (Culex quinquefasciatus). Também os níveis de prevalência são baixos e, possivelmente, mantidos por um influxo de áreas rurais onde reservatórios silvestres e/ou dinâmicas de transmissão vetorial mais favoráveis mantêm uma prevalência mais elevada.

ABSTRACT Stachytarpheta is one of the largest genera of Verbenaceae, found mainly in the campos rupestres of Brazil. We describe a new species, Stachytarpheta lajedicola, and report for the first time the occurrence of the genus in limestone outcrops. The new species is endemic to the Caatinga domain, northern Minas Gerais state, growing in an open karst formation of the municipality of Matias Cardoso, locally known as Lajedão. Its main diagnostic characteristics are the branches with well-developed longitudinal edges, leaves with attenuate to caudate apex, and inflorescences with linear bracts, exceeding the calyx in length. We provide a detailed description, illustrations, photographs, a geographic occurrence map, and comparisons with the morphologically similar species. Stachytarpheta lajedicola may be considered Critically Endangered (CR), and the biological importance of Lajedão and the conservation of the new species are discussed.

Abstract Background Management delays imply worse outcomes in rheumatoid arthritis (RA) and, therefore, should be minimized. We evaluated changes in diagnostic and treatment delays regarding RA in the last decades in Brazil. Methods Adults fulfilling the ACR/EULAR (2010) criteria for RA were assessed. Delays in diagnosis and treatment, and the frequencies of early management initiation within thresholds (windows of opportunity) of 3, 6, and 12 months from symptoms onset were evaluated. The Mann–Kendall trend test, chi-squared tests with Cramer’s V effect sizes and analysis of variance were conducted. Results We included 1116 patients: 89.4% female, 56.8% white, mean (SD) age 57.1 (11.5) years. A downward trend was found in diagnostic (tau = - 0.677, p < 0.001) and treatment (tau = - 0.695, p < 0.001) delays from 1990 to 2015. The frequency of early management increased throughout the period, with ascending effect sizes across the 3-, 6-, and 12-month windows (V = 0.120, 0.200 and 0.261, respectively). Despite all improvements, even in recent years (2011–2015) the diagnostic and treatment delays still remained unacceptably high [median (IQR): 8 (4–12) and 11 (5–17) months, respectively], with only 17.2% of the patients treated within the shortest, 3-month window. Conclusion The delays in diagnosis and treatment of RA decreased during the last decades in Brazil. Improvements (effect sizes) were greater at eliminating extreme delays (≥ 12 months) than in attaining really short management windows (≤ 3 months). Very early treatment was still an unrealistic goal for most patients with RA.

Abstract Background Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. Methods Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed “early” when the rheumatologist was the first or second physician consulted after symptoms onset, and “late” when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. Results We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6–36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: −0.25 [−0.46, −0.04] and − 0.196 [−0.306, −0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. Conclusions Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.

Abstract Since the first reported case of COVID-19 in Brazil, the public and private educational system started to close. Up to November 2020, scientific discussions about the return of schooling activities have been rarely performed by the national scientific community and police-makers. The great delay of school returning in Brazil contrasts with successful international strategies of school reopening worldwide and seems counterintuitive with the reopening of non-essential activities. Here, important issues to be considered before and during school reopening are reviewed and discussed. COVID-19 testing is essential to avoid disease spreading, but high cost of individual RT-qPCRs impairs an extensive testing strategy for school returning. To reduce costs and increase the speed of diagnosis, we tested the efficiency of a pooled-sample PCR strategy in a cohort of the educational staff in the city of Macaé/RJ, finding five asymptomatic individuals (0,66%) among the 754 people tested. Thus, a polled-sample PCR testing strategy of the educational staff might prevent infection spreading in schools at a reasonable cost. We discuss how our test strategy could be coupled with internationally recognized safety rules to allow for a safe school return and how countries from different world regions are dealing with educational activities during COVID-19 pandemic.

RESUMO Objetivo: Avaliar casos de tumores de partes moles do Serviço de Oncologia Ortopédica do Hospital PUC-Campinas e determinar o perfil epidemiológico no período de fevereiro de 2012 a novembro de 2019, associando à participação de um hospital que não é referência na abordagem e tratamento da patologia. Métodos: Foi realizada uma análise exploratória de dados com 72 pacientes entre 18 e 81 anos, de ambos os sexos e com diagnóstico de tumor de partes moles. Eles foram avaliados e divididos em dois grupos: (I) de etiologia primária e (II) de etiologia metastática Resultados: Do total de 146 pacientes admitidos, 22 vieram a óbito, sendo 9 pacientes do Grupo I, e 13 do Grupo II. Para todos os pacientes com tumor de partes moles, com idade entre 51 e 58 anos, admitidos no período, a probabilidade de sobrevida após 46 meses foi de 71,84%, enquanto do Grupo I foi de 22,7%, e do Grupo II foi de 91,43%. Conclusão: Apesar da escassez de dados epidemiológicos relacionados ao tumor de partes moles, os dados apreciados no serviço do hospital, que não é referência no tratamento dessa condição, são compatíveis com os dados apresentados em hospitais especializados no Brasil, assim, corroborando a literatura. Nível de Evidência III, Estudo Retrospectivo Comparativo Prognóstico.
ABSTRACT Objective: To evaluate cases of soft tissue tumors at the Orthopedic Oncology service of the PUC-Campinas Hospital and determine the epidemiological profile in the period from February 2012 to November 2019, associating the participation of a non-reference hospital in the approach and treatment of the pathology. Methods: This study evaluated 72 patients aged 18 to 81 years, of both sexes and diagnosed with soft tissue tumor and divided into two groups: (I) primary etiology and (II) metastatic etiology. Results: Of 146 patients admitted, 22 resulted in deaths, with 9 patients from Group I, and 13 from Group II. For all patients with soft tissue tumor, aged between 51 and 58 years, admitted in the period, the probability of survival after 46 months was 71.84%, Group I’s was 22.7% and Group II’s 91.43%. Conclusion: Despite the scarcity of epidemiological data related to soft tissue tumor, the data appreciated in the hospital’s service, not a reference in treating this type of condition, are compatible with the data presented in specialized hospitals in Brazil, thus, in confluence with the literature. Level of Evidence III, Comparative, Prognostic and Retrospective Study.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Resumo: Introdução: O ensino da neurorradiologia na graduação médica deve ser encarado como uma ferramenta de integração para o estudo interdisciplinar de radiologia, anatomia e neurologia. Na prática, percebe-se uma limitação dos alunos em adquirir tais conhecimentos, seja pela “neurofobia”, seja pela falta de conhecimentos anatômico-radiológicos prévios e também pela carência de materiais didáticos integrados direcionados para a graduação. Contudo, há poucos trabalhos relatando as dificuldades encontradas pelos alunos no aprendizado de neurorradiologia . Objetivo: Avaliar a percepção dos estudantes de medicina sobre as dificuldades do aprendizado em neurorradiologia. Método: Estudo quantitativo, realizado com estudantes de medicina matriculados no segundo e no sétimo semestres de uma universidade de Fortaleza. Os dados foram obtidos por meio de questionário estruturado com 12 questões de respostas sim ou não. As questões versaram sobre as possíveis dificuldades encontradas para aquisição do conhecimento neurorradiológico, dentre elas: à carência de material didático direcionado, à falta de integração com a neurologia, à necessidade de conhecimentos básicos radiológicos e anatômicos, ao volume de assunto, e às limitações das metodologias ativas e tradicionais. Resultados: Foram analisados 181 questionários. Grande parte discente refere como dificuldade a necessidade de ter conhecimentos básicos prévios de radiologia (80,1%); de neuroanatomia (77,5%); e de correlacionar radiologia e neuroanatomia (70,9%). Quando comparados os grupos do 2o semestre e do 7o semestre, houve uma tendência maior a apontar a ausência de conhecimento prático de neurologia pelos alunos do 2o semestre como um fator de maior dificuldade para o aprendizado de neurorradiologia (82,6% versus 67,4%, com p<0,0018). Quando perguntados sobre a utilidade da criação de um e-Book direcionado para a graduação para o aprendizado de neurorradiologia, 85,6% dos alunos responderam afirmativamente; no caso de um aplicativo, 92,3% concordaram. Quanto à correlação entre a neurorradiologia e a prática médica, 98,3% responderam que é um conhecimento útil e necessário. Conclusão: Na opinião dos estudantes, os conhecimentos prévios de neuroanatomia e de neurologia clínica são importantes para o aprendizado de neurorradiologia. A elaboração de um material como e-book ou aplicativo com foco em integrar o ensino dessas disciplinas é considerada uma boa alternativa para facilitar a compreensão da neurorradiologia.
Abstract: Introduction: The teaching of neuroradiology in undergraduate medical school must be seen as an integration tool for the interdisciplinary study of radiology, anatomy and neurology. In practice, there is a limitation on the part of students in acquiring such knowledge, either due to “neurophobia”, or due to the lack of previous anatomical-radiological knowledge and also due to the lack of integrated didactic materials aimed at undergraduate school. However, there are few studies reporting the difficulties encountered by students in learning neuroradiology. Objective: To assess the perception of medical students about learning difficulties in neuroradiology. Method: Quantitative study, carried out with medical students enrolled in the second and seventh semesters of a university in Fortaleza. Data were obtained through a structured questionnaire with 12 yes or no answer questions. The questions addressed the possible difficulties encountered in acquiring neuroradiological knowledge, among them: the lack of targeted didactic material, the lack of integration with neurology, the need for basic radiological and anatomical knowledge, the large volume of content to study, and the limitations of active and traditional methodologies. Results: 181 questionnaires were analyzed. Most students report as difficulties: the need for basic knowledge of radiology (80.1%); neuroanatomy (77.5%); and to correlate radiology and neuroanatomy (70.9%). When comparing the 2nd semester and 7th semester groups, there was a greater tendency to point out the lack of practical knowledge of neurology by 2nd-semester students as a factor of greater difficulty in learning neuroradiology (82.6% versus 67.4 %, with p <0.0018). When asked about the usefulness of creating an e-book aimed at undergraduate students for learning neuroradiology, 85.6% of the students answered affirmatively; in the case of a mobile application, 92.3% agreed. As for the correlation between neuroradiology and medical practice, 98.3% answered that it is useful and necessary knowledge. Conclusion: In the students’ opinion, previous knowledge of neuroanatomy and clinical neurology is important for learning neuroradiology. The development of material such as an e-book or mobile application focused on integrating the teaching of these disciplines is considered a good alternative to facilitate the understanding of neuroradiology.

RESUMO Objetivo: Definir o perfil epidemiológico e os principais determinantes de morbimortalidade dos pacientes cirúrgicos não cardíacos de alto risco no Brasil. Métodos: Estudo prospectivo, observacional e multicêntrico. Todos os pacientes cirúrgicos não cardíacos admitidos nas unidades de terapia intensiva, ou seja, considerados de alto risco, no período de 1 mês, foram avaliados e acompanhados diariamente por, no máximo, 7 dias na unidade de terapia intensiva, para determinação de complicações. As taxas de mortalidade em 28 dias de pós-operatório, na unidade de terapia intensiva e hospitalar foram avaliadas. Resultados: Participaram 29 unidades de terapia intensiva onde foram realizadas cirurgias em 25.500 pacientes, dos quais 904 (3,5%) de alto risco (intervalo de confiança de 95% - IC95% 3,3% - 3,8%), tendo sido incluídos no estudo. Dos pacientes envolvidos, 48,3% eram de unidades de terapia intensiva privadas e 51,7% de públicas. O tempo de internação na unidade de terapia intensiva foi de 2,0 (1,0 - 4,0) dias e hospitalar de 9,5 (5,4 - 18,6) dias. As taxas de complicações foram 29,9% (IC95% 26,4 - 33,7) e mortalidade em 28 dias pós-cirurgia 9,6% (IC95% 7,4 - 12,1). Os fatores independentes de risco para complicações foram Simplified Acute Physiology Score 3 (SAPS 3; razão de chance − RC = 1,02; IC95% 1,01 - 1,03) e Sequential Organ Failure Assessment Score (SOFA) da admissão na unidade de terapia intensiva (RC =1,17; IC95% 1,09 - 1,25), tempo de cirurgia (RC = 1,001; IC95% 1,000 - 1,002) e cirurgias de emergências (RC = 1,93; IC95% 1,10 - 3,38). Em adição, foram associados com mortalidade em 28 dias idade (RC = 1,032; IC95% 1,011 - 1,052) SAPS 3 (RC = 1,041; IC95% 1,107 - 1,279), SOFA (RC = 1,175; IC95% 1,069 - 1,292) e cirurgias emergenciais (RC = 2,509; IC95% 1,040 - 6,051). Conclusão: Pacientes com escores prognósticos mais elevados, idosos, tempo cirúrgico e cirurgias emergenciais estiveram fortemente associados a maior mortalidade em 28 dias e mais complicações durante permanência em unidade de terapia intensiva.
ABSTRACT Objective: To define the epidemiological profile and the main determinants of morbidity and mortality in noncardiac high surgical risk patients in Brazil. Methods: This was a prospective, observational and multicenter study. All noncardiac surgical patients admitted to intensive care units, i.e., those considered high risk, within a 1-month period were evaluated and monitored daily for a maximum of 7 days in the intensive care unit to determine complications. The 28-day postoperative, intensive care unit and hospital mortality rates were evaluated. Results: Twenty-nine intensive care units participated in the study. Surgeries were performed in 25,500 patients, of whom 904 (3.5%) were high-risk (95% confidence interval - 95%CI 3.3% - 3.8%) and were included in the study. Of the participating patients, 48.3% were from private intensive care units, and 51.7% were from public intensive care units. The length of stay in the intensive care unit was 2.0 (1.0 - 4.0) days, and the length of hospital stay was 9.5 (5.4 - 18.6) days. The complication rate was 29.9% (95%CI 26.4 - 33.7), and the 28-day postoperative mortality rate was 9.6% (95%CI 7.4 - 12.1). The independent risk factors for complications were the Simplified Acute Physiology Score 3 (SAPS 3; odds ratio - OR = 1.02; 95%CI 1.01 - 1.03) and Sequential Organ Failure Assessment Score (SOFA) on admission to the intensive care unit (OR = 1.17; 95%CI 1.09 - 1.25), surgical time (OR = 1.001, 95%CI 1.000 - 1.002) and emergency surgeries (OR = 1.93, 95%CI, 1.10 - 3.38). In addition, there were associations with 28-day mortality (OR = 1.032; 95%CI 1.011 - 1.052), SAPS 3 (OR = 1.041; 95%CI 1.107 - 1.279), SOFA (OR = 1.175, 95%CI 1.069 - 1.292) and emergency surgeries (OR = 2.509; 95%CI 1.040 - 6.051). Conclusion: Higher prognostic scores, elderly patients, longer surgical times and emergency surgeries were strongly associated with higher 28-day mortality and more complications during the intensive care unit stay.

Resumo A literatura sobre medição e gestão de desempenho mostra o estágio ainda embrionário desses processos na indústria da construção. Assim, este trabalho tem como objetivo avaliar os processos de medição e gestão de desempenho no setor de construção. Por meio de três estudos de caso em empresas construtoras evidencia-se que os sistemas de medição de desempenho (SMD) em uso nas empresas estão focados apenas em aspectos operacionais da medição de desempenho, não sendo, portanto, capazes de promover uma gestão que integre finalidades mais estratégicas, como influenciar o comportamento dos atores e proporcionar aprendizado e melhoria, elementos fundamentais para o alcance dos objetivos organizacionais. Assim, o estudo contribui com a literatura de gestão da construção ao aprofundar e ampliar as discussões sobre os conceitos de medir e gerar o desempenho, trazendo as novas formas de examinar o tema com base em diversos conceitos que ascendem principalmente das ciências administrativas e econômicas. Contribui também ao expandir a evidência empírica que reforça a evolução lenta dos SMD no setor de construção.
Abstract The literature on performance measurement and management shows the embryonic stage of these processes in the construction industry. Thus, this paper aimed to evaluate the Performance Measurement and Management (PMM) process in the construction sector. A multiple case study in three construction companies showed that the performance measurement systems (PMS) in use in these companies are focused on operational aspects of performance measurement, and are unable to promote their integrated management for more strategic purposes, such as influencing the behaviour of the actors and providing learning and improvement, fundamental elements to the successful of any organisation. Thus, this study contributes to construction management literature by expanding and deepening the discussion on the differences between measuring and managing performance, offering new ways to interpret the PMM, based on different concepts emerging from administrative and economic disciplines. This project also contributes by offering empirical evidence that reinforces the slow evolution of this subject in the construction sector.

ABSTRACT. The aim of this study was to evaluate nutritional value, fermentation losses, and aerobic stability of elephant grass silage (Pennisetum purpureum Schum.) treated with exogenous fibrolytic enzymes. The experiment was conducted in a completely randomized design with four replicates (experimental silos) and five levels of fibrolytic enzymes (0, 1.5, 3.0, 4.5 and 6.0%). For this, the elephant grass was ensiled at 70 days of age in plastic buckets with 20L capacity. Silos were opened 60 days after sealing. Analyses were made for chemical composition, in vitro dry matter digestibility (IVDMD), effluent losses (EL), gas losses (GL) and dry matter recovery (DMR), as well as the aerobic stability of the silage. Data were analyzed with PROC REG of SAS® University, at 5% probability. There was an increase in IVDMD content (p < 0.0001) and reduction in NDF and ADF contents (p < 0.0001) according to enzyme levels. These results were related to the increase in the degradation of fiber fractions. There were higher EL (p = 0.0062) as a function of enzyme levels and aerobic deterioration after silo opening, at all levels tested. Thus, it can be concluded that the exogenous fibrolytic enzymes change the chemical composition of elephant grass silage, and increase its digestibility and nutritional value. Moreover, when used alone as an additive, fibrolytic enzymes are not able to recover all dry matter of this silage (with effluent and gas losses), and are not able to maintain aerobic stability in the first hours after opening the silos.

Resumo: Introdução: Além de proporcionar vários benefícios, o aprendizado móvel oferece novos ambientes de ensino. Desenvolvemos e validamos um aplicativo de smartphone para residentes de ortopedia e traumatologia, a fim de ajudá-los no estudo e, consequentemente, na aprovação do exame do Conselho de Ortopedia e Traumatologia. Métodos: Trata-se de um estudo quantitativo para validar a aplicação móvel. O instrumento foi desenvolvido para as plataformas iOS® e Android®, em português e gratuito. Os 132 participantes do estudo, divididos em três grupos, usaram a ferramenta. Adotaram-se dois questionários: a já validada System Usability Scale (SUS) e um outro criado pelos autores (devidamente validado) para avaliar a praticidade e viabilidade do aplicativo como ferramenta de aprendizagem. O modo, a frequência absoluta e o percentual das variáveis estudadas foram cruzados pelo teste de Fisher ou qui-quadrado de Pearson. Resultados: Dos 132 participantes, 55,3% possuem iOS®. Todos os participantes afirmaram que já haviam usado um aplicativo em seus smartphones; seis (4,5%) mencionaram que nunca utilizaram aplicativos para fins acadêmicos (valor de p < 0,001); 100% destacaram a utilidade dessa tecnologia no desenvolvimento teórico do residente; e 124 (93,9%) concordaram que se trata de um método auxiliar de aprendizagem para médicos ortopedistas em geral. Obteve-se um escore médio da SUS de 84,2 (DP 10,8) com margem de erro de 1,9. O escore da SUS variou de 82,4 a 86,1 (IC95%). O coeficiente alfa de Cronbach foi de 0,797. Conclusão: O aplicativo desenvolvido foi bem-sucedido nos exames realizados e pode ser uma alternativa no ensino médico na área ortopédica.
Abstract: Introduction: Mobile learning offers several benefits, such as new learning environments. We developed and validated a smartphone application for orthopedics and traumatology residents in an attempt to assist their study and, consequently, pass the Board of Orthopedics and Traumatology Exam. Methods: quantitative study, aimed at the validation of a mobile application. It was developed for the iOS® and Android® platforms, in the Portuguese language, and free of charge. 132 participants, divided into three groups, used the tool. A validated questionnaire - System SUS Scale (SUS) - and a questionnaire created by the authors (properly validated) were used to assess the practicality and viability of the application as a learning tool. The mode, the absolute frequency and the percentage of the studied variables were crossed by Fisher's test or Pearson's chi-square test. Results: of the 132 participants, 55.3% have iOS®. All participants said they had already used an application on their smartphones, whereas 6 (4.5%) mentioned never having used applications for academic purposes (p value <0.001). 100% said it was a useful technology in the resident's theoretical development. 124 (93.9%) agreed it was an auxiliary learning method for orthopedic doctors in general. An average SUS score of 84.2 (SD 10.8) was obtained with a margin of error of 1.9. The SUS score varied between 82.4 and 86.1 (95% CI). Cronbach's alpha coefficient was 0.797. Conclusion: the developed application was successful in the tests performed and can be an alternative in medical education in the orthopedic area.
