Association of iron deficiency with atrial fibrillation recurrence after pharmacological cardioversion
Authors: Valeev M. Kh. , Khasanov N. R.
Published: July 2023

Aim. This study aims to assess the association between iron deficiency (ID) and recurrences of atrial fibrillation (AF) in patients after pharmacological cardioversion with amiodarone within 12 months.

Material and methods. The open-label, prospective, single-center study included 198 patients with non-valvular paroxysmal AF after successful pharmacological cardioversion with amiodarone. Group I included 116 patients with ID, and group II — 82 patients with normal iron status. The primary end-point of the study was the development of symptomatic AF recurrences within 12 months after the cardioversion which was estimated by the Kaplan-Meier method. The differences were considered statistically significant if p-value was <0,05.

Results. Absolute ID was found in patients of group I; anemia was revealed in 85,3% of the patients. The groups did not differ in basic clinical and demographical parameters, concomitant diseases and drug therapy. Along with that, the I group patients were older (the median was 73 (64,8-79) years old and 69 (63-75) years old, respectively, р=0,008), and their left ventricular mass was larger (the median was 145 (115-176) g and 132,5 (118,2-145) g, respectively, р=0,004). The sinus rhythm restoration in group I required less dose of amiodarone (the median was 450 (300-600) mg and 1000 (600-1200) mg, respectively, р<0,001) and less time from the start of the drug administration to the rhythm restoration (the median was 7 (3-10) and 12 (9-18) hours, respectively, р<0,001). During the 12-month follow-up period, 49 (42,2%) patients in group I and 16 (19,5%) patients in group II developed AF recurrences (р=0,0008), hazard ratio 2,64 (95% confidence interval: 1,5-4,65) (р=0,0003).

Conclusion. ID is associated with the increase of the number of symptomatic AF recurrences in patients after pharmacological cardioversion with amiodarone within 12 months.

As a clinical case, we present the "portrait" of a woman patient with acquired mitral valve (MV) defect against the background of infective endocarditis which was diagnosed during the third trimester of pregnancy. The patient underwent mitral valve replacement surgery with biological prosthesis "KemKor" followed by two successful deliveries. In 18 years after the correction of the mitral valve defect, she developed valve prosthesis dysfunction therefore, she underwent endovascular transcatheter implantation of bioprosthesis by method "prosthesis-into-prosthesis" in the mitral position.

This clinical case is unique in terms of the reasoning the biological prosthesis choice to correct acquired MV defect in a patient of reproductive age, the long-term period of the bioprosthesis functioning and the correction of further developed valve dysfunction using the techniques of transcatheter implantation.

ABSTRACT Objectives: the present study aims to evaluate cancer patients related to the catheter flow and the general satisfaction of these patients. Methods: we studied 233 individuals diagnosed with cancer who underwent chemotherapy treatment through venous access through portocath between January 2015 and December 2019. Results: 97% of the patients consulted had palliative chemotherapy, and 99.1% of patients reported satisfaction with the implantation process and treatment method. Regarding catheter flow according to venous return and drip during drug infusion, 98.7% of individuals presented good flow. Conclusions: the results show that catheter flow was satisfactory in all implant sites observed and emphasize the advantages of using a totally implanted catheter. This benefice happens due to the reduction of emotional factors that cause stress in cancer patients receiving chemotherapy, as well as the reduction of trauma and discomfort experienced by patients during the infusion of peripheral chemotherapy.

ABSTRACT Introduction: many revascularization techniques were designed to reduce the imbalance of ischemia-reperfusion injury. This study’s objective is to evaluate retrograde reperfusion (RR) compared to sequential anterograde reperfusion (AR), with and without the washout technique (WO). Method: this prospective cohort study collected data from 94 deceased donor orthotopic liver transplants and divided it into three groups: RR with WO (RR+WO), AP with WO (AR+WO), and AP without WO (AR). This study did not assign the reperfusion technique to the participants. The primary outcome considered the early graft dysfunction, and secondary outcomes included post-reperfusion syndrome (PRS), post-reperfusion lactate, surgery fluid balance, and vasoactive drug dose during the surgery. Results: 87 patients were submitted to the final analysis-29 in the RR+WO group, 27 in the AR+WO group, and 31 in the AR group. Marginal grafts prevalence was not significantly different between the groups (34% vs. 22% vs. 23%; p=0.49) and early graft dysfunction occurred at the same rate (24% vs. 26% vs. 19%; p=0.72). RR+WO reduced serum post-reperfusion lactate (p=0.034) and the incidence of significant PRS (17% vs. 33% vs. 55%; p=0.051), but norepinephrine dosing >0.5mcg/kg/min were not different during the surgery (20,7% vs. 29,6% vs. 35,5%, p=0.45). Conclusions: primary outcome was not significantly different between the groups; however, intraoperative hemodynamic management was safer using the RR+WO technique. We theorized that the RR+WO technique could reduce the incidence of PRS and benefit marginal graft survival following diseased donor orthotopic liver transplantation.

RESUMO Introdução: o melanoma cutâneo (MC) é uma neoplasia maligna de comportamento agressivo, derivada das células melanocíticas, geralmente causado pela associação de interação da suscetibilidade genética e a exposição ambiental. A biópsia do linfonodo sentinela (LNS) é um procedimento utilizado para rastreamento de doentes com necessidade ou não de linfadenectomia, diminuindo a exposição do paciente a cirurgias maiores. Objetivos: correlacionar a carga do tumor no LNS com a mortalidade de pacientes com MC. Métodos: foram examinados retrospectivamente prontuários e lâminas histológicas de doentes com MC submetidos a biópsia de LNS atendidos no HC-Unicamp entre o período compreendido de 2001 a 2021. Os LNS positivos foram mensurados quanto ao tamanho da área de infiltração do tumor, para análise da profundidade de invasão (PI), menor proximidade com a cápsula (MPC) e carga do tumor (CT). As associações entre as variáveis foram analisadas pelo teste Exato de Fisher, com pós teste de Bonferroni e Wilcoxon. Resultados: foram identificados 105 pacientes com biópsia de LNS, sendo nove (8,6%) casos com LNS positivo. A média de MDC, CT e PI foram 0,14 mm, 32,10 mm, e 2,33 mm, respectivamente. Doentes com tumores T2 e T3 apresentaram maior chance de acometimento do LNS (p=0,022). Nenhum paciente com LNS positivo foi a óbito durante o acompanhamento. Conclusão: doentes que apresentaram tumores maiores (T2 e T3) apresentaram maior chance de linfonodos sentinelas positivos. Além do tamanho do tumor, a presença de maior carga do tumor demonstrou que os mesmos podem ser beneficiados pela biópsia de LNS.

ABSTRACT Introduction: cutaneous melanoma (MC) is a malignant neoplasm derived from melanocytic cells with an aggressive behavior. It is usually associated with the multifactorial interaction of genetic susceptibility and environmental exposure, usually ultraviolet radiation. Despite advances in treatment, the disease remains relentless with poor prognosis. Sentinel lymph node (SLN) biopsy is a technique used to screen patients in need of lymph node dissection. Objectives: to correlate the tumor burden in the SLN with the mortality of patients undergoing SLN biopsy. Methodology: the medical records and histological slides of patients with MC who underwent SLN biopsy treated at HC-Unicamp from 2001 to 2021 were retrospectively analyzed. The positive SLN were measured according to the size of the tumor infiltration area, for analysis of the depth of invasion (DI), closest proximity to the capsule (CPC) and tumor burden (TB). For statistical analysis, associations between variables were analyzed using Fishers exact test, with post Bonferroni test and Wilcoxon test. Results: 105 records of patients who underwent SLN biopsy of MC were identified. Of these, nine (8.6%) had positive SLN and 81 (77.1%) had negative SLN. The performed lymphadenectomies resulted in 55.6% (n=5) affected, 22.2% (n=2) without disease and 22.2% (n=2) were not performed. Mean CPC, TB, and DI were 0.14mm, 32.10mm and 2.33mm, respectively. Patients with T2 and T3 tumors were more likely to show the SLN affected (p=0.022). No patient with positive SLN died during follow-up. Conclusion: patients who presented T3 staging are the ones who most presented positive SLN.

ABSTRACT Introduction: the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates. Methods: Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors. Results: 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones. Conclusion: the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

Published: July 2023

Nutrition during pregnancy is essential for the health of the pregnant woman, the development of the fetus, and the prevention of complications related to pregnancy and the postpartum period. This study described the factors associated with high consumption of ultra-processed foods among pregnant women. This prospective cohort study was performed from February 2016 to November 2019 in two health units in the city of Rio de Janeiro, Brazil, with data from 344 pregnant women. The first interview was conducted in the prenatal visit at less than 20 gestational weeks, the second at 34 gestational weeks, and the third at two months postpartum. Diet was assessed in the last interview using a food frequency questionnaire, and food items were classified according to NOVA. The percentage of ultra-processed foods consumption was estimated by tertile distribution, and the third tertile represented the highest consumption. Based on the hierarchical analysis model, the associations between ultra-processed foods consumption and sociodemographic, reproductive health, pregestational, behavioral, and pregnancy variables were assessed using a multinomial logistic regression model. Older women had lower ultra-processed foods consumption (OR = 0.33; 95%CI: 0.15-0.71). Few years of schooling (up to 7 years; OR = 5.58; 95%CI: 1.62-19.23), history of a previous childbirth (OR = 2.48; 95%CI: 1.22-5.04), history of two or more previous childbirths (OR = 7.53; 95%CI: 3.02-18.76), and no history of regular physical activity before pregnancy (OR = 2.40; 95%CI: 1.31-4.38) were risk factors. The identification of risk and protection factors allows for the establishment of control measures and encouragement of healthy practices during prenatal care.

ABSTRACT: This research evaluated the agronomic performance through mixed models, and determined the genetic divergence between black oat genotypes. The experiment was carried out at Federal University of Santa Maria, Frederico Westphalen/RS. Fourteen black oat genotypes were evaluated, being 11 lines developed by Breeding Program of University, and three commercial cultivars (IAPAR 61, UPFA 21 - Moreninha and, IPR Cabocla). We evaluated quantitative traits associated to plant height, cycle, dry mass yield and seeds yield; and 19 qualitative traits, being these morphological descriptors. The results showed that lines UFSMFW 2-05 and UFSMFW 2-07 stand out with characteristics such as early cycle, higher dry mass and grain yield. Divergence analysis revealed the formation of three distinct groups, indicating the presence of variability. These results suggested the potential for the development of new cultivars of black oat, presenting early cycle and good grain yield.

Resumo Estudos indicam que a desigualdade de gênero, exclusão social e fatores históricos de opressão fomentam o distanciamento entre as meninas e a Ciência. Diante disso, nossa pesquisa teve como objetivo compreender a participação das meninas e meninos em atividades investigativas e analisar a contribuição das ações de duas mediadoras para a participação das meninas em equidade de gênero. O público consistiu em 241 estudantes de escolas públicas e privadas situadas na região metropolitana de São Paulo, com idade entre 13 e 14 anos do ensino fundamental (8º e 9º anos). Os encontros foram registrados em áudio e vídeo. O software livre IRaMuTeQ foi utilizado para fazer a análise lexical das transcrições das 10 turmas. Destaca-se uma participação equitativa nas discussões, em que meninas e meninos fizeram enunciações, levantaram hipóteses indicando grande porcentagem argumentativa no experimento de colisão de carrinhos, provavelmente, devido ao planejamento e embasamento teórico das mediadoras para ações equitativas.

Resumo A relação entre uma população desinformada e o risco de contaminação por agentes químicos existe, e é a diferença entre um ambiente seguro de incidentes danosos à saúde e ao meio ambiente, e um mesmo ambiente sujeito a toda sorte de eventos de impactos que levam à deterioração ambiental. Com base nessa problemática, utilizou-se de um estudo qualitativo, do tipo exploratório-descritivo, visando verificar as percepções ambientais sobre o uso e descarte de produtos tóxicos pelos alunos da terceira e quarta etapa da modalidade Educação de Jovens e Adultos (EJA). Utilizou-se como instrumento de coleta de dados, questionários estruturados, observação e análise documental. O componente curricular Ciências da Natureza tem sido ministrado de maneira incipiente sobre conteúdos relacionados à toxicidade, e as propriedades químicas de produtos domissanitários, na respectiva modalidade.
Modo de pensar que subyace a los obstáculos epistemológicos de aprendizaje del tópico Síntesis de Proteínas en estudiantes universitarios de primer año
Authors: Miño Mariela Haydée , Ospina Natalia , Garofalo Sofia Judith
Published: July 2023

Resumen En esta investigación se identificaron modos de pensar que subyacen a los obstáculos epistemológicos de aprendizaje del Proceso de Síntesis Proteica (PSP) en estudiantes de primer año de carreras biomédicas de la Universidad de Buenos Aires. Tres modelos científicos ad hoc sobre el PSP ofrecieron el marco conceptual y metodológico para la interpretación de las respuestas de los estudiantes, las que provinieron de entrevistas y preguntas incluidas en el examen de la materia. Se diferenciaron obstáculos de tipo puente (OTP) y de tipo brecha (OTB). Un análisis en profundidad permitió conocer modos de pensar que sustentan a los OTP, identificando estrategias de tipo heurísticas que alertan acerca del riesgo epistemológico que dichos obstáculos implican. Estos resultados sugieren la necesidad de reorganizar los contenidos a enseñar en modelos científicos ad hoc contextualizados, para facilitar a los estudiantes la construcción de una mirada sistémica y holística del PSP.

Abstract The study aim was to evaluate the cytotoxic activity, using the MTT test [3-(4,5-Dimethilthiazol-2-yl)-2,5-diphenil tetrazolium bromide], from the crude extract of Picrasma crenata (Pau Tenente) and its isolated compounds, quassin and parain, in culture of rat liver tumor cells (HTC). The test was carried out exposing the cells for 24, 48 and 72 hours to concentrations of 5, 10, 50, 100, 200, 300, 400, 500 and 1000 μg of crude extract of Pau Tenente/mL of culture medium and 1, 5, 10, 15, 20, 40, 60, 80 and 100 μg of quassin or parain compounds/mL of culture medium. The absorbances averages results obtained showed that the crude extract did not present cytotoxicity for the HTC cells in all the concentrations and evaluated times. For quassin, the concentrations of 80 and 100 μg/mL were cytotoxic, after 72 hours of treatment. For parain, the concentrations of 1, 5, 20, 40, 60, 80 and 100 µg/mL, in 72 hours, were cytotoxic, revealing a new activity for this compound. Thus, the results demonstrate a first indication of the cytotoxic activity of compounds quassin and parain, adding an important social and economic value to them, and may have application in future research and in pharmaceutical industry.

Abstract The production of duck meat in the republic was previously based on the use of 4-5 lines and populations of the Beijing breed, where the Medeo cross lines (M-1 paternal and M2-maternal) were the most widespread. At the same time, many domestic lines and populations, such as the cross “Bishkulskaya Tsvetnaya”, “Kyzylzharsky”, whose livestock is concentrated in the Northern region, represent rich genetic material and can be used to create new crosses. This article describes the productive and breeding qualities of ducks of the local population in the Northern region of Kazakhstan, the data obtained make it possible for further purposeful breeding work to create, preserve highly productive poultry, providing highly efficient production of eggs and meat, adapted to both industrial conditions and conditions of keeping in small-scale and farms. On the basis of “Bishkul Poultry Farm” LLP, we obtained results on the assessment of productive and breeding indicators of ducks of the local population.
Nem formal, nem informal: a diversidade das práticas nas organizações partidárias brasileiras

Published: July 2023

RESUMO Introdução: As práticas internas dos partidos políticos brasileiros são formais ou informais? A aderência aos estatutos, de um lado, ou o personalismo nos procedimentos partidários, de outro, estão associados aos padrões de democracia interna de cada partido? Questionamos os diagnósticos correntes acerca da prevalência da informalidade e das relações pessoais nas organizações partidárias do Brasil. Materiais e métodos: Baseado em survey inédito e de abrangência nacional com dirigentes e ex-dirigentes subnacionais de 25 agremiações partidárias, avaliamos o nível de aderência às regras, o personalismo e a democracia intrapartidária de uma série de processos típicos dessas organizações: seleção de candidatos, financiamento de campanha, intervenções em diretórios, escolhas de dirigentes etc. Ao todo, foram analisadas 2.421 respostas validadas, abrangendo 36 questões (do total de 52 no questionário), entre março e maio de 2020. Resultados: As análises descritivas e as escalas z-score demonstram que as práticas não são homogeneamente formais ou informais, variando significativamente as estruturas internas de cada partido. De modo complementar, os modelos logit multivariados demonstraram que a percepção de formalidade (aderência às regras e impessoalidade) está associada à democracia intrapartidária em diferentes processos. Partidos que adotam regras formais mais estritas e providas de mecanismos efetivos de enforcement tendem a optar por práticas internas mais inclusivas que dispersam o poder entre diferentes camadas da máquina partidária. Discussão: Após quatro décadas de experiência democrática, cabe superar as suposições assentadas em previsões institucionais ou estudos de casos sobre as organizações partidárias brasileiras. As evidências apontam que os partidos são diferentes entre si e essas agremiações não podem ser reduzidas à pessoalidade e à informalidade. As associações constatadas entre pluralidade institucional dos partidos e seus diferentes graus de democracia interna ilustram essa necessidade de buscar abordagens sustentadas por empiria nos estudos sobre instituições e práticas organizacionais.

RESUMO Este artigo revisita a literatura clássica sobre o movimento homossexual brasileiro (MHB). Discute as dificuldades inerentes à categoria movimento social e demonstra como se deu a divulgação e a incorporação do mito fundador e da noção de que a imprensa gay artesanal, à exceção de Snob e Gente Gay, apenas conteria paródias e fofocas. Ao final, propõe uma metodologia para o exame da constituição de movimentos sociais cujos atores são marcados por dinâmicas de desqualificação (pessoas LGBTI+, negros, povos originários, mulheres, prostitutas), a qual, ademais de processual, contemple o esforço adicional para superar a identidade deteriorada.

ABSTRACT Light is essential for providing energy for photosynthetic reactions and has a complex and not yet fully understood effect on heliconia growth and yield. Thus, the objective of this study was to evaluate the effect of light intensity on the growth and photosynthesis of heliconia under semi-arid conditions and to screen potential genotypes tolerant to high solar irradiation levels during the vegetative stage. The experiment was conducted in Petrolina, PE, Brazil, whose geographic coordinates are 09° 19’ 14” S, 40° 32’ 40” W, with an average altitude of 387 m. The experimental design used was in randomized blocks, arranged in a split-plot scheme, and the treatments were composed of two light intensities (full sun and 50% shading) and five genotypes (Heliconia psittacorum x H. spathocircinata cv. Golden Torch; H. psittacorum cv. Red Opal; H. bihai cv. Lobster Claw Two; H. rauliniana and H. rostrata). Growth and gas exchange assessments were conducted on the 100th day after the trial initiation. Light intensity (full sun and 50% shading) did not influence the rates of photosynthesis (A), stomatal conductance (gs), or transpiration (E) of plants. However, the isolated effect of the genotype revealed that plants of cv. Red Opal, H. bihai, H. rauliniana, and cv. Golden Torch had higher values of A, gs, and E. Overall, shading improved plant growth. We conclude that the genotypes H. psittacorum cv. Red Opal, and H. psittacorum cv. Golden Torch exhibited the greatest tolerances to high solar irradiance conditions.

ABSTRACT The intercropping between maize and forage species is an alternative commonly used within farming systems. Competition among crops may be a limiting factor in intercropping, compromising maize and forage yield. Although necessary, the literature does not provide satisfactory answers on the interaction of forage crops launched in the market recently, such as BRS Zuri, intercropped with maize. Therefore, techniques such as the use of herbicide subdoses come in as an option to suppress forage growth, making simultaneous cultivation feasible. Thus, the present study aimed to evaluate the effects of glyphosate herbicide subdoses on the development of Panicum maximum cv. BRS Zuri intercropped with Roundup Ready® (RR) maize and how this interaction reflects on the weed population, forage yield, and biometric and yield variables of maize. The experimental design was randomized blocks with treatments consisting of six subdoses of glyphosate herbicide (0, 48, 96, 240, 480, and 960 g acid equivalent [a.e.] ha-1) and maize in monoculture with four replications. For the conditions of this study, the dose of 480 g a.e. ha-1 of glyphosate may be an alternative since there was weed suppression and adequate forage development. Maize yield was not affected by the presence of forage.

Published: July 2023

ABSTRACT Soil erosion studies using rainfall simulators are generally expensive and time consuming. Thus, the aim of this study was to develop a prototype of an automatic runoff collector, capable of real-time quantifying runoff volume and soil loss in field trials using a rainfall simulator. The used sensors were chosen based on the type A uncertainty computed from different volumes of water and concentrations of sediment. Through specific programming, the runoff volume, sediment concentrations and the time of occurrence of the collections corresponding to each 200 cm³ of runoff were recorded on a micro-SD card. The robustness of the calibration and the programming developed were also evaluated in the Arduino Mega® 2560 microcontroller. The pressure (PSI.420) and turbidity (ST100) sensors were selected for developing the prototype, which was evaluated in the field with the InfiAsper rainfall simulator. Then, the data collected automatically by the sensors were compared to those obtained by manual measurement. The automatic runoff collector equipped with the PSI.420 and ST100 sensors has potential to obtain and store runoff data, and it was effective in evaluating the erosion process, generating mean errors of 12.25 and 13.16% for runoff volume and soil loss, respectively. The proposed prototype has a low cost of manufacture, in addition to optimizing the collection of erosion data in studies with rainfall simulators.

Method: methodological study with development of three videos for incarcerated women with themes chosen by them (Menstrual Cycle, Arterial Hypertension and Epilepsy), developed in four stages: construction of storyboards, validation by expert judges, construction of videos and validation by the public. The validation process was performed by seven judges with the Health Educational Content Validation Instrument, the Suitability Assessment of Materials and readability analysis. For approval, it was established that the agreement between judges should be higher than 80%, and the adequacy, according to the SAM, should be 40-100%. The incarcerated women evaluated the videos in August 2022, in a women's public prison in Ceará, using the Assistive Technology Assessment Instrument, considering the level of agreement of the positive responses above 70%. Results: the validation instrument result of the storyboards ranged from 0.92 to 1.0. In the Suitability Assessment, a percentage of 85.2% to 88.8% was reached, categorizing the materials as superior. As for readability, the values obtained (70.9 to 78.1) place the texts as easy or very easy to read. The evaluation by the target audience showed that the videos were adequate (97.8-100%). Conclusion: the three videos constructed were suitable for incarcerated women, with evidence of content validity and may be used in health education actions for this public.

RESUMO Objetivos: construir e verificar a aplicabilidade clínica de um fluxograma para avaliação de crianças e adolescentes que serão submetidos à cateterização intravenosa periférica, segundo fatores de risco para insucesso do procedimento. Método: estudo metodológico e observacional, que seguiu diretrizes e etapas do instrumento AGREEII para a construção do fluxograma decisório para punção intravenosa periférica difícil. Depois, verificou-se a aplicabilidade clínica com crianças e adolescentes, após aprovação do mérito ético, sendo o desfecho principal o índice de sucesso na primeira tentativa de punção. Verificou-se, por análise estatística, a associação do desfecho com os fatores de risco levantados. A coleta dos dados foi realizada entre os meses de novembro de 2018 e fevereiro de 2019. Resultado: na primeira etapa do estudo realizou-se revisão de literatura para levantamento dos fatores de risco para a difícil punção sendo encontrados prematuridade, menos de três anos, pele mais pigmentada, obesidade, doenças crônicas, desidratação, vasos difíceis de serem visualizados e/ou palpados, história de múltiplas punções e complicações da terapia intravenosa. Após aplicação do fluxograma, verificou-se que 96,3% das crianças e adolescentes avaliados tinham risco para serem puncionados mais de uma vez, e que 43,9% foram submetidos a mais de um procedimento para o sucesso. Os que não obtiveram sucesso na primeira tentativa tinham menos de três anos, possuíam doença crônica, difícil visualização e palpação dos vasos e histórico de múltiplas punções. Conclusão: a construção do fluxograma foi fundamentada nos fatores de risco para a difícil punção identificados na literatura. A aplicabilidade clínica mostrou que pode ser instrumento útil para identificar crianças e adolescentes com risco para insucesso da punção.

ABSTRACT. Increased depressive severity has been linked to neurocognitive impairment. Aerobic exercise (AE) is an efficient technique for improving cognitive function. However, studies indicating the importance of AE to neurophysiological and neuropsychological functions in the depressed elderly using event-related potentials (ERPs) are scarce. Objectives: This study aimed to identify the potential benefits of AE on neurophysiological and neuropsychological functions. Methods: A total of 30 depressed older adults (AE group: n=15; control group (CG): n=14) were recruited based on the inclusion and exclusion criteria. The AE group was subjected to an 8-week-period AE program (3 times/week for 30 min per session) at moderate intensity, determined using heart rate maximum (HRmax). The training intensity was set at 50% HRmax and increased by 5% in subsequent weeks. Pre- and post-training measures for neurophysiological function were tested using ERP-P300 (amplitude-μV and latency-ms) and also for neuropsychological functions using the trail making test (TMT), mini mental status examination (MMSE), and everyday cognition questionnaire (ECog). Results: In the experimental group, statistically significant improvements were observed when analyzed for all 3 (group-by-time interaction effect, main effect of time, and main effect of group), in both neurophysiological functions (*p<0.001) and neuropsychological functions (*p<0.001), except for ECog scores, where the results were insignificant for the main effect of a group. Correlation analysis demonstrated no association between neurophysiological and neuropsychological functions (*p>0.05). Conclusion: Findings showed that 8 weeks of AE training may be a promising approach to improve cognitive functions in depressed older adults. However, considering relatively small number of patients, the question arises for effectiveness in other populations.

Abstract: Introduction: This essay is based on the teaching experience of theTranscultural Psychiatry Program at the University of São Paulo (ProSol,Programa de Psiquiatria Transcultural da Universidade de São Paulo) and on theoretical foundations in the field of cultural psychiatry. Objective: To highlight the importance of teaching cultural psychiatry for the training of psychiatry residents. Results: Brazilian psychiatry, throughout its history, was marked by the incorporation of knowledge from developed countries with little concern for the Brazilian reality. The teaching of cultural aspects, in the psychiatric field, makes it possible to reactivate the importance of Brazilian reality and specificity for the teaching of residents. Conclusion: The central thesis of this essay is that the teaching of cultural psychiatry is a form of decolonization of teaching, insofar as it makes psychiatrists more apt to face the different clinical scenarios in a diverse country full of contradictions such as Brazil.

Abstract: Introduction: In Brazil, the lack of studies evaluating self-esteem in medical students is evident. In the academic field, it is known that individuals with high self-esteem and resilience are more likely to be successful. In previous studies, resilience was negatively associated with anxiety and Burnout Syndrome (BS). The BS has become a public health problem due to its increased incidence, especially among medical professionals during the coronavirus disease (COVID-19) pandemic, making it essential to expand and develop this issue. Objectives: To evaluate the level of self-esteem in medical students and its association with the degree of resilience and burnout during the pandemic. Method: A cross-sectional cohort study was conducted with medical students from the first to the eighth semesters at Centro Universitário Christus in Fortaleza - CE, Brazil. The students answered three surveys: in the beginning of the semester, at the midterms and during finals. We applied the Maslach Burnout Inventory, Wagnild and Young’s resilience scale, the Rosenberg Self-Esteem scale and a sociodemographic questionnaire. Results: Students with higher levels of emotional exhaustion showed less professional efficiency (P < 0.001). Disbelief and professional efficiency are inversely related (P < 0.001). There was no significant variation in the prevalence of burnout throughout the semester (P = 0.593). However, this prevalence has been high since the first period of the study. Additionally, the higher the resilience, the higher the self-esteem (P < 0.001). Conclusion: Medical students show elevated levels of BS. There was no statistically significant variation in burnout, resilience, and self-esteem throughout the semester. Therefore, further studies are necessary to analyze these variables.

Resumo: Introdução: Ao final de 2019, um dos grandes desafios do século XXI veio à tona e atingiu o mundo todo. O longo período de isolamento levou as pessoas a se adaptar a uma nova forma de trabalho e estudo. A mesma medida foi adotada pelos cursos de Medicina, o que resultou em novas metodologias de aprendizagem. Objetivo: Este estudo teve como objetivo analisar, por meio de uma revisão integrativa, dados referentes ao processo de adaptação da educação médica on-line durante a pandemia. Método: Trata-se de uma revisão integrativa de literatura em que se utilizaram os dados das seguintes plataformas: PubMed, Biblioteca Virtual em Saúde (BVS), Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), Scientific Electronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). A pesquisa teve início em julho de 2021. Resultado: Inicialmente, com a aplicação dos critérios de inclusão, obteve-se um total de 841 artigos oriundos das bases de dados selecionadas. Após a exclusão de artigos duplicados, esse número foi reduzido a 242 artigos. Após a aplicação dos critérios de exclusão, chegou-se a 22 artigos selecionados para o estudo. Conclusão: Como a Medicina é um curso prático em sua maioria, é fundamental o contato físico dos estudantes com os pacientes, de modo a desenvolver habilidades essenciais para um médico de qualidade, tanto em técnicas da semiologia médica como na desenvoltura da relação médico-paciente. Porém, a necessidade de um modo de aprendizagem surgiu com a pandemia, e o ensino não podia parar. Diante dos pontos levantados na literatura pesquisada, o senso comum seria a aplicação de um método de ensino híbrido - on-line e presencial - (visando à otimização de tempo e ao rompimento de barreiras geográficas, sem deixar de lado a importância da prática clínica), excepcionalmente on-line (quando houver situações extraordinárias, a exemplo da pandemia de Covid-19) ou somente presencial (em regiões onde é inviável a aplicação do e-learning).

Abstract: Introduction: At the end of 2019, one of the great challenges of the 21st century emerged, affecting the whole world. The long period in isolation made people adapt to the way they work and study, and this same measure was taken in the medical course, bringing new methodologies and learning. Objective: To analyze, through an Integrative Review, data on how the process of adapting online medical education was carried out during the pandemic. Methods: This is an Integrative Literature Review and data search was conducted in the PubMed, Virtual Health Library (BVS), Coordination for the Improvement of Higher Education Personnel (CAPES), Scientific Electronic Library Online (SCIELO) and Latin American and Caribbean Literature on Health Sciences (LILACS) databases. The search began in July 2021. Results: Initially, with the application of the inclusion criteria, a total of 841 articles were obtained from the selected databases. After excluding duplicate articles, this number was reduced to 242 articles. After applying the exclusion criteria, 22 articles were selected for the study. Conclusion: It is known that Medicine is mostly a practical course, the physical contact of students with patients is essential to develop essential skills for a quality physician, both in medical semiology techniques and in the skills necessary to establish the doctor-patient relationship. However, the need for a way of learning arose with the pandemic and teaching could not stop. In view of the points raised in the literature research, the common sense would be the application of a hybrid teaching method - online and face-to-face - (aimed at optimizing time and breaking geographic barriers, without neglecting the importance of clinical practice), exceptionally online (when there are extraordinary situations, such as the COVID-19 pandemic) or only in person (in regions where the application of e-learning is not feasible).
