Abstract Background: Currently, there is no uniform and official terminology in Portuguese for reflectance confocal microscopy analysis, despite the increasing number of Brazilian dermatologists using this new tool. Objective: To present the terminology in Brazilian Portuguese for the description of reflectance confocal microscopy and establish the first Brazilian consensus on terms related to normal skin and cutaneous tumors. Methods: 10 Brazilian specialists from different institutions and states of Brazil were selected to evaluate the best corresponding terms in Portuguese for normal skin, melanocytic and non-melanocytic tumors. The terms used were translated from international consensuses in the English language. The modified Delphi method was used to create the consensus in 3 steps. Results: The terms considered the most appropriate in the Portuguese language to describe the findings of normal skin, melanocytic and non-melanocytic lesions in the reflectance confocal microscopy analysis were presented. Study limitations: The limitations of the present study include the number of participants and limited regional representation (only two of the five Brazilian regions were represented). Conclusion: This Brazilian consensus represents an opportunity for dermatologists and physicians specializing in cutaneous oncology to become familiar with reflectance confocal microscopy, propagating the technique in clinical and research environments to stimulate national and international publications on this subject.

Abstract Black population health (BPH) can be understood, at the same time, as a field of study, of social intervention, and of cultural domain. This complex sphere of knowledge and practice emerged from the demands of social movements, especially those of black women, to face concrete public health problems. As a field of study, scientific production in Brazil is still incipient. Given this context, we conducted this investigation to demonstrate how the production on BPH has been structured in Brazil in the last three decades. This is an integrative systematic review that aims to synthesize and analyze the scientific knowledge already produced on this topic. We selected 400 works among articles, theses, and dissertations published between 1998 and 2020 and analyzed the evolution of the production volume, its locus (states, institutions, scientific areas, and territorial scope of the studies), themes and methodologies, as well as some of these intercrossing. As a result, we found a notable increase in the research volume in recent years, in an interdisciplinary field with wide thematic diversity in relation to pioneer studies. This evolution may point to a process of consolidation of the field of studies on health and race in Brazil, even if the signs presented are ambiguous.

Abstract Background: Currently, excess ventilation has been grounded under the relationship between minute-ventilation/carbon dioxide output ( V ˙ E − V ˙ CO 2). Alternatively, a new approach for ventilatory efficiency ( η E V ˙) has been published. Objective: Our main hypothesis is that comparatively low levels of η E V ˙ between chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are attainable for a similar level of maximum and submaximal aerobic performance, conversely to long-established methods ( V ˙ E − V ˙ CO 2 slope and intercept). Methods: Both groups performed lung function tests, echocardiography, and cardiopulmonary exercise testing. The significance level adopted in the statistical analysis was 5%. Thus, nineteen COPD and nineteen CHF-eligible subjects completed the study. With the aim of contrasting full values of V ˙ E − V ˙ CO 2 and η V ˙ E for the exercise period (100%), correlations were made with smaller fractions, such as 90% and 75% of the maximum values. Results: The two groups attained matched characteristics for age (62±6 vs. 59±9 yrs, p>.05), sex (10/9 vs. 14/5, p>0.05), BMI (26±4 vs. 27±3 Kg m2, p>0.05), and peak V ˙ O 2 (72±19 vs. 74±20 %pred, p>0.05), respectively. The V ˙ E − V ˙ CO 2 slope and intercept were significantly different for COPD and CHF (27.2±1.4 vs. 33.1±5.7 and 5.3±1.9 vs. 1.7±3.6, p<0.05 for both), but η V ˙ E average values were similar between-groups (10.2±3.4 vs. 10.9±2.3%, p=0.462). The correlations between 100% of the exercise period with 90% and 75% of it were stronger for η V ˙ E (r>0.850 for both). Conclusion: The η V ˙ E is a valuable method for comparison between cardiopulmonary diseases, with so far distinct physiopathological mechanisms, including ventilatory constraints in COPD.

Resumo Fundamento: Atualmente, o excesso de ventilação tem sido fundamentado na relação entre ventilação-minuto/produção de dióxido de carbono ( V ˙ E − V ˙ CO 2). Alternativamente, uma nova abordagem para eficiência ventilatória ( η E V ˙) tem sido publicada. Objetivo: Nossa hipótese principal é que níveis comparativamente baixos de η E V ˙ entre insuficiência cardíaca crônica (ICC) e doença pulmonar obstrutiva crônica (DPOC) são atingíveis para um nível semelhante de desempenho aeróbico máximo e submáximo, inversamente aos métodos estabelecidos há muito tempo (inclinação V ˙ E − V ˙ CO 2 e intercepto). Métodos: Ambos os grupos realizaram testes de função pulmonar, ecocardiografia e teste de exercício cardiopulmonar. O nível de significância adotada na análise estatística foi 5%. Assim, dezenove indivíduos elegíveis para DPOC e dezenove indivíduos elegíveis para ICC completaram o estudo. Com o objetivo de contrastar valores completos de V ˙ E − V ˙ CO 2 e η E V ˙ para o período de exercício (100%), correlações foram feitas com frações menores, como 90% e 75% dos valores máximos. Resultados: Os dois grupos tiveram características correspondentes para a idade (62±6 vs 59±9 anos, p>.05), sexo (10/9 vs 14/5, p>0,05), IMC (26±4 vs 27±3 Kg m2, p>0,05), e pico V ˙ O 2 (72±19 vs 74±20 % pred, p>0,05), respectivamente. A inclinação V ˙ E − V ˙ CO 2 e intercepto foram significativamente diferentes para DPOC e ICC (207,2±1,4 vs 33,1±5,7 e 5,3±1,9 vs 1,7±3,6, p<0,05 para ambas), mas os valores médios da η E V ˙ foram semelhantes entre os grupos (10,2±3,4 vs 10,9±2,3%, p=0,462). As correlações entre 100% do período do exercício com 90% e 75% dele foram mais fortes para η E V ˙ (r>0,850 para ambos). Conclusão: A η E V ˙ é um método valioso para comparação entre doenças cardiopulmonares, com mecanismos fisiopatológicos até agora distintos, incluindo restrições ventilatórias na DPOC.

BACKGROUND Leishmania tarentolae is a non-pathogenic species found in lizards representing an important model for Leishmania biology. However, several aspects of this Sauroleishmania remain unknown to explain its low level of virulence. OBJECTIVES We reported several aspects of L. tarentolae biology including glycoconjugates, proteolytic activities and metabolome composition in comparison to pathogenic species (Leishmania amazonensis, Leishmania braziliensis, Leishmania infantum and Leishmania major). METHODS Parasites were cultured for extraction and purification of lipophosphoglycan (LPG), immunofluorescence probing with anti-gp63 and resistance against complement. Parasite extracts were also tested for proteases activity and metabolome composition. FINDINGS Leishmania tarentolae does not express LPG on its surface. It expresses gp63 at lower levels compared to pathogenic species and, is highly sensitive to complement-mediated lysis. This species also lacks intracellular/extracellular activities of proteolytic enzymes. It has metabolic differences with pathogenic species, exhibiting a lower abundance of metabolites including ABC transporters, biosynthesis of unsaturated fatty acids and steroids, TCA cycle, glycine/serine/threonine metabolism, glyoxylate/dicarboxylate metabolism and pentose-phosphate pathways. MAIN CONCLUSIONS The non-pathogenic phenotype of L. tarentolae is associated with alterations in several biochemical and molecular features. This reinforces the need of comparative studies between pathogenic and non-pathogenic species to elucidate the molecular mechanisms of virulence during host-parasite interactions. nonpathogenic non However L glycoconjugates amazonensis braziliensis major. major . major) LPG, , (LPG) antigp63 antigp anti gp anti-gp6 complement surface gp6 complementmediated mediated lysis intracellularextracellular intracellular extracellular enzymes transporters steroids cycle glycineserinethreonine glycine serine threonine glyoxylatedicarboxylate glyoxylate dicarboxylate pentosephosphate pentose phosphate pathways features hostparasite host parasite interactions (LPG antigp6 anti-gp

Abstract Price of iron ore is affected by instabilities of microeconomic balance between supply and demand. Periods of equilibrium adjustment result in huge swings, growth or global recession. They also impact the viability of mineral enterprises and generate consequences to important global economic scenarios. This research aims to evaluate the market variables capable of influencing the price of iron ore through multivariate statistical techniques. Principal component analysis and multiple linear regression, booth multivariate statistical techniques were used. The studied variables were rate export of iron ore and concentrates from Brazil, steel production from China, steel production from Japan, production from Europe, steel production from the United States, steel production from India, steel price, coal price, China’s Construction Gross Domestic Production, United States construction index, oil price and global oil production.

ABSTRACT There are different decision levels with distinct decision makers in a decentralized Supply Chain, for example, shippers and carriers. Nevertheless, most studies are conducted considering only one decision-making level. The carrier is the decision-making agent in Dynamic Vehicle Allocation (DVA) problem and allocates vehicles to maximize its profit, usually delaying shipping. It is necessary to respect the partnership principle. This paper presents the DVA problem using bi-level programming. The shipper’s objective is to minimize shipping delays, while the carrier’s objective is to maximize profits. The exact algorithm is used to solve the Bi-level DVA problem. The results show potential applications in logistics, decreasing both transportation delays and costs when synchronizing carrier’s and shippers’ decisions. Chain example carriers Nevertheless decisionmaking making level (DVA profit principle bilevel bi programming shipper s profits Bilevel Bi logistics decisions

Abstract The oil from the fruit of peach palm or Pupunha (Bactris gasipaes) is an example of a material with low-cost and good antioxidant capacity. However, Conventional methods for measuring oil content are time-consuming, labor-intensive and use toxic chemicals. In this sense, the aim of this study was evaluated fast and non-destructive spectroscopy methods, such as Near Infrared (NIR) and Time-Domain Nuclear Magnetic Resonance (TD-NMR) (CPMG and ROSE pulse sequences), to quantify the oil content in pupunha flours collected in the amazon forest. For this, 93 samples were used and the results showed three distinct levels of oil in the samples: high, medium and low oil content. Furthermore, the determination coefficient (R2) reached values of 0.92, 0.92 and 0.70 for NIR, TD-NMR (ROSE) and TD-NMR (CPMG), respectively. Therefore, the NIR and TD-NMR (ROSE) methods demonstrate a higher prediction efficiency, with the NIR achieving 100% classification of the samples.

ABSTRACT BACKGROUND: Brazil is facing increasing cycles of numbers of infected people and deaths resulting from coronavirus disease 2019 (COVID-19). This situation involves a series of factors, including the behavior of the population, that can be decisive for controlling the disease. OBJECTIVE: To determine the knowledge, attitudes and practices of the Brazilian population regarding COVID-19. DESIGN AND SETTING: Cross-sectional survey-type study, conducted using a population sample from different Brazilian states. METHODS: A quantitative, descriptive and analytical approach was used. Sampling was done according to convenience and via snowballing. The data collection instrument was a knowledge, attitudes and practices system. RESULTS: 1,655 people from all over Brazil participated in the survey; 80% were living in the southern region and 70.15% were female. More than 90% had knowledge and good attitudes relating to the means of transmission, preventive care and symptoms associated with COVID-19, although their knowledge and attitudes were not fully reflected in daily practices, for which there was lower adherence (80%). Greater knowledge was correlated with older participants, larger number of children, female sex and marital status; better attitude, with female sex and complete higher education; and better practices, with greater age, larger number of children and female sex. CONCLUSION: A large part of the population has general knowledge about COVID-19, but not all knowledge was applied in practice. Older people, females and university graduates stood out as the best informed and most committed to controlling the disease.

ABSTRACT This paper presents a robust deterministic method for the treatment of uncertainty in decision-making systems based on Sonar Method. It introduces uncertainty into mathematical models as interval numbers. This work proposes an interactive approach that identifies the efficient vertices of the Multiobjective Linear Programming (MOLP), where some or all the coefficients of the objective functions, constraints or limits of the constraints are interval of real numbers. The method identifies robust solutions to MOLP under uncertainty, showing how the interactive approach presented in this paper can provide the possibility of exploring in new decision support methodologies.

RESUMO As leucemias são caracterizadas pela proliferação de células imaturas da linhagem branca, denominadas blastos, na medula óssea e/ou sangue. Dentre elas destacamos a Leucemia Mielóide Aguda Monocítica, que representa uma neoplasia maligna, cuja proliferação anormal de monoblastos resulta na supressão das células da série mielóide. Manifestações orais são comuns, surgindo no início da doença e também associadas à quimioterapia durante o tratamento gerando complicações que comprometem a oncoterapia. O presente trabalho trata-se de um paciente portador deste tipo agressivo de leucemia, com complicações bucais da doença e posteriormente, do tratamento oncológico. Destaca ainda a atuação do cirurgião-dentista em fases distintas do tratamento realçando a importância da manutenção da saúde bucal em pacientes oncológicos. A presença do Cirurgião-Dentista na equipe multiprofissional contribui para diminuição das manifestações que ocorrem tanto devido à doença quanto ao tratamento, garantindo melhor qualidade de vida do paciente oncológico e evitando maiores gastos ao sistema de saúde.

ABSTRACT Leukemia’s are characterized by the proliferation of immature white blood cells, called blasts, in the bone marrow and / or blood. Among them, we highlight the Monocytic Acute Myeloid Leukemia, which represents a malignant neoplasm whose unnatural monoblast proliferation results in suppression of myeloid series cells. Oral manifestations are common, arising at the onset of the disease and are also associated with chemotherapy during treatment leading to complications that compromise oncotherapy. The present study deals with a patient with this type of aggressive leukemia, with oral complications of the disease and later, oncological treatment. It also give prominence the performance of the dental surgeon in distinct phases of the treatment emphasizing the importance of maintaining oral health in cancer patients. The presence of the Dentist in the multi-professional team contributes to the reduction of manifestations that occur both due to the disease and the treatment, ensuring a better quality of life for cancer patients and avoiding higher expenses to the health system.

Resumo: Introdução: A síndrome do impostor (SI) é caracterizada como a incapacidade de internalizar o sucesso e a tendência de atribuir o sucesso a causas externas, como sorte, erro ou ignorância de outras pessoas. Apesar do recente aumento no número de publicações sobre SI, estudos sobre essa condição em estudantes de graduação em Medicina e o impacto sobre a saúde mental são escassos. Objetivo: Este estudo teve como objetivo avaliar a prevalência de SI e sua associação com a síndrome de burnout (SB) e depressão. Método: Foi realizado um estudo transversal, descritivo e quantitativo com alunos de graduação em Medicina de um centro universitário do Nordeste do Brasil. Utilizaram-se um questionário sociodemográfico, a Clance Impostor Phenomenon Scale (CIPS), a Maslach Burnout Inventory - Student Survey (MBI-SS) e o Patient Health Questionnaire-9 (PHQ-9). Resultado: Entre os 425 alunos avaliados, 47 (11,06%) apresentaram sintomas leves; 151 (35,53%), moderados; 163 (38,35%) graves; e 64 (15,06%), muito graves. Fatores como não ser casado, ter baixo nível de atividade física e não contribuir para a renda familiar foram associados a sintomas graves ou muito graves de SI (p < 0,001, p = 0,032 e p = 0,025, respectivamente). O diagnóstico médico prévio de depressão e ansiedade e o uso de antidepressivos também foram associados a sintomas graves ou muito graves de SI (p = 0,019, p = 0,006 e p = 0,011, respectivamente). Além disso, houve uma correlação positiva entre os escores da CIPS e do PHQ-9 (p = 0,459, p < 0,001), e uma associação entre SB (dimensões de exaustão emocional e descrença) e SI (p < 0,001). Conclusão: Este estudo identificou associação entre SI e SB e depressão em estudantes de graduação em Medicina. Outros estudos com intervenção na SI podem demonstrar um impacto positivo na saúde mental.

Abstract: Introduction: The Impostor Syndrome (IS) is characterized as inability to internalize success and tendency to attribute success to external causes such as luck, error or ignorance of other people. Despite the recent increase in the number of IS publications, studies on this condition in undergraduate medical students and the impact on mental health are scarce. Objective: The aim of this study was to assess the prevalence of IS and its association with Burnout Syndrome (BS) and depression. Methods: A cross-sectional, descriptive and quantitative study was carried out with undergraduate medical students at a university center in Northeast Brazil. A sociodemographic questionnaire, the Clance Impostor Phenomenon Scale (CIPS), the Maslach Burnout Inventory - Student Survey (MBI-SS) and the Patient Health Questionnaire-9 (PHQ-9) were used. Results: Of the 425 students assessed, 47 (11.06%), 151 (35.53%), 163 (38.35%) and 64 (15.06%) had mild, moderate, severe and very severe IS symptoms, respectively. Not being married, having a low level of physical activity and not contributing to family income were associated with severe or very severe IS symptoms (p < .001, p = .032 and p = .025, respectively). Previous medical diagnosis of depression, anxiety and use of antidepressants are also associated with severe or very severe IS symptoms (p = .019, p = .006 and p = .011, respectively). In addition, there was a positive correlation between the CIPS and PHQ-9 scale scores (p = .459, p < .001), and an association between BS (Emotional Exhaustion and Cynicism dimensions) and IS (p < .001). Conclusion: This study identified an association between IS and BS and depression among undergraduate medical students. Further studies with interventions against IS may show a positive impact on mental health.

RESUMO JUSTIFICATIVA E OBJETIVOS A literatura sugere que a enzima óxido nítrico sintase (NOS) desempenha um papel importante tanto na doença periodontal (DP) quanto na dor orofacial (DOF), embora poucos estudos associem estas duas condições simultaneamente. O objetivo deste estudo foi analisar a expressão da NOS em pacientes com DP e DOF em comparação a controles sem estas condições. CONTEÚDO Foram consultadas as bases de dados eletrônicas (Pubmed, Web of Science, Scopus, Cochrane Library, BBO, Lilacs e Clinical Trial) para identificar os estudos potencialmente relevantes publicados até abril de 2021. As pesquisas resultaram em 1.960 estudos, dos quais 11 foram selecionados para serem avaliados criticamente. Os critérios definidos na questão PECO (População, Exposição, Comparação e Desfecho) foram usados para selecionar títulos e resumos por dois revisores independentes. A avaliação metodológica dos estudos selecionados foi realizada de acordo com a ferramenta Effective Public Health Practice Project (EPHPP). CONCLUSÃO As evidências científicas demonstraram que a NOS desempenha um importante papel na patogênese da DP e da DOF, já que sua expressão está aumentada em pacientes com estas condições. Porém, estudos genéticos sobre mutações dos genes do óxido nítrico sintase endotelial (eNOS) em pacientes com migrânea e cefaleia em salvas não evidenciaram a esperada suscetibilidade a dor. Além disso, estudos sobre a associação da expressão da NOS na DP e na DOF, ocorrendo simultaneamente, são escassos. Este estudo pode subsidiar futuras pesquisas sobre NOS na correlação de duas doenças muito frequentes como a DP e a DOF.

ABSTRACT BACKGROUND AND OBJECTIVES The literature suggests that the enzyme nitric oxide synthase (NOS) plays an important role in both periodontal disease (PD) and orofacial pain (OP), although few studies associate these two conditions simultaneously. The objective of this study was to evaluate the expression of the NOS enzyme in PD and OP, in comparison to those patients who did not present PD and/or OP. CONTENTS Seven electronic databases (Pubmed, Web of science, Scopus, Cochrane Library, BBO, LILACS, Clinical trial) were used to identify the potentially relevant studies published until April 2021. The research resulted in 1,960 studies, of which 11 were selected to be critically evaluated. Two independent reviewers selected titles and abstracts using the criteria defined in the PECO question (Population, Exposure, Comparison, Outcome). The methodological evaluation of the selected studies was carried out according to the Effective Public Health Practice Project (EPHPP). CONCLUSION: Scientific evidence demonstrated that NOS may play a key role in the pathogenesis of PD and OP, since its expression is increased in patients with these conditions. However, genetic studies on endothelial nitric oxide synthase (eNOS) gene mutations in patients with migraine and cluster headache did not indicate the expected susceptibility to pain. In addition, studies on the association of NOS expression in PD and OP, occurring simultaneously, are scarce. This review may support future research on NOS in two very common correlated diseases such as PD and OP.

Resumo A pandemia da COVID-19 trouxe incontáveis desafios para as instituições de saúde de todo o mundo, em especial as localizadas em países como o Brasil, com grande dimensão territorial e muitas diferenças sociais e econômicas. Este informe técnico tem como objetivo publicizar as ações realizadas e os produtos desenvolvidos no Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) antes e durante a pandemia - no período de 31 de janeiro até 04 de setembro de 2020 - enfrentando-a com eficiência e eficácia, buscando a sustentabilidade institucional. A mobilização do corpo profissional da instituição foi fundamental para a construir protocolos de atendimento, adaptar as estruturas físicas na assistência ao paciente em âmbito hospitalar e ambulatorial, cuidar dos profissionais de saúde, ofertar as atividades de ensino e pesquisa na modalidade à distância, articular os membros da gestão para tomar decisões baseadas em dados sistematicamente coletados sobre a situação da pandemia em tempo real. Todas as ações foram realizadas com um uníssono objetivo de atender a todos os pacientes acometidos pela COVID-19 admitidos na instituição.

Abstract The COVID-19 pandemic has brought countless challenges to the health institutions around the world, especially those located in countries such as Brazil, with large territorial dimensions and many social and economic differences. This technical report aims to publish the actions carried out and the products developed at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) before and during the pandemic - from January 31st to September 4th, 2020 - facing it efficiently and effectively, seeking institutional sustainability. The mobilization of the professional staff at the institution was fundamental to create protocols ofas-sistance, adapt the physical structures in the hospital and outpatient care, care for the health professionals, offer teaching and research activities in the distance mode, articulate management members to make decisions based on systematically collected data on the pandemic situationat real time. All actions were carried out with a single objective of assisting all the patients affected by COVID-19 admitted at the institution.
