Exploring the potential of omics technologies in medicinal plant research: a review in Colombia / Explorando el potencial de las tecnologías ómicas en la investigación de plantas medicinales: una revisión en Colombia

This review presents advances in the implementation of high - throughput se quencing and its application to the knowledge of medicinal plants. We conducted a bibliographic search of papers published in PubMed, Science Direct, Google Scholar, Scopus, and Web of Science databases and analyzed the obtained data using VOSviewer (versi on 1.6.19). Given that medicinal plants are a source of specialized metabolites with immense therapeutic values and important pharmacological properties, plant researchers around the world have turned their attention toward them and have begun to examine t hem widely. Recent advances in sequencing technologies have reduced cost and time demands and accelerated medicinal plant research. Such research leverages full genome sequencing, as well as RNA (ribonucleic acid) sequencing and the analysis of the transcr iptome, to identify molecular markers of species and functional genes that control key biological traits, as well as to understand the biosynthetic pathways of bioactive metabolites and regulatory mechanisms of environmental responses. As such, the omics ( e.g., transcriptomics, metabolomics, proteomics, and genomics, among others) have been widely applied within the study of medicinal plants, although their usage in Colombia is still few and, in some areas, scarce.

Ethnobotanical knowledge on non-conventional food plants and medicinal plants in Extractivist Reserve in the Brazilian Amazon / Conocimiento etnobotánico sobre plantas alimenticias no convencionales y plantas medicinales en una Reserva Extractivista en la Amazonía Brasileña

Information on the knowledge and ways of using food and medicinal plants by traditional populations, family farmers and Brazilian native population in the Amazon is essential to guarantee the food sovereignty of these groups. This study was conducted using semi-structured interviews applied to local respondents. A total of 269 species of both non-conventional food plants and medicinal plants were identified, distributed in 83 botanical families and 198 genera. The Arecaceae and Lamiaceae families had the highest species richness (11 and 7, respectively). The Shannon-Wiener (H') and Pielou (J') diversity indices were considered high (5.02 and 0.9, respectively) when compared to other ethnobotanical works. In the environment in which these families are found, these species become the only food and medicinal resources available.

Este estudio se realizó utilizando entrevistas semiestructuradas aplicadas a encuestados locales. Se identificaron un total de 269 especies tanto de plantas alimenticiasno convencionales como de plantas medicinales, distribuidas en 83 familias botánicas y 198 géneros. Las familias Arecaceae y Lamiaceae tuvieron la mayor riqueza de especies (11 y 7, respectivamente). Los índices de diversidad de Shannon-Wiener (H') y Pielou (J') fueron considerados altos (5,02 y 0,9, respectivamente) en comparación con otros trabajos etnobotánicos. En el ambiente en que se encuentran estas familias, estas especies se convierten en los únicos recursos alimenticios y medicinales disponibles.

Postgraduate medical education in Colombia. Proposals to improve it

After 70 years of the formalization of medical specialties in Colombia, very little progress has been made in the educational models for the acquisition of clinical competencies in these postgraduate programs. Furthermore, although there is already a law on human resources in health, the Colombian medical education system lacks specific regulations on the training of health professionals (physicians) in the different medical specialty programs offered in the country. Likewise, at present, factors such as the financial crisis of public hospitals, the limited number of accredited hospitals and the growing number of medical schools and specialization programs, affect the comprehensive and equal development of medical competencies of professionals who are trained as specialists in the different postgraduate medical programs offered in Colombia. In view of the above, the purpose of this article is to present a proposal for postgraduate medical education that prioritizes the adequate acquisition of competencies over compliance with the time required to complete the curricula of the different medical specialties. However, this involves several prerequisites: a regulatory body in charge of overseeing and monitoring the training of medical residents or specialists in the country; strong training in university teaching for professors practicing in medical schools and university hospitals; the standardization of the graduates profile; adequate financing of university hospitals, as well as appropriate support in the process of accreditation as such, and the self-evaluation and continuous improvement of postgraduate medical programs.

Después de 70 años de la formalización de las especialidades médicas en Colombia, ha habido muy pocos avances en los modelos educativos para la adquisición de competencias clínicas en estos programas de posgrado. Además, a pesar de que ya hay una ley sobre el talento humano en salud, en el sistema educativo médico colombiano no hay regulaciones específicas sobre la formación de profesionales de la salud (médicos) en los diferentes programas de especialidades médicas ofrecidos en el país. Igualmente, en la actualidad factores como la crisis financiera de los hospitales públicos, el escaso número de hospitales acreditados y el creciente número de facultades de medicina y de programas de especialización afectan la adquisición integral e igualitaria de competencias médicas de los profesionales que se forman como especialistas en los diferentes programas de posgrado médico ofrecidos en Colombia. Teniendo en cuenta lo anterior, el propósito de este artículo es presentar una propuesta de educación médica de posgrado que priorice la adecuada adquisición de competencias por encima del cumplimiento del tiempo fijado para completar los planes de estudios de las diferentes especialidades médicas. Sin embargo, para esto se requieren varios aspectos: un ente regulatorio encargado de vigilar y monitorear la formación de los residentes o especialistas médicos en el país; una fuerte capacitación en docencia universitaria a los profesores que ejercen en las facultades de medicina y hospitales universitarios; la homogenización del perfil de los egresados; una adecuada financiación de los hospitales universitarios, así como un apropiado acompañamiento en su proceso de acreditación como tal, y la autoevaluación y mejoramiento continuo de los posgrados médicos.

"Penumbra sign" in knee pain: a case of distal femur osteomyelitis

"Penumbra sign" is a characteristic finding in magnetic resonance imaging (MRI) of Brodie's abscess, a rare variant of subacute osteomyelitis. We aimed to discuss the imaging finding penumbra sign that will help in the diagnosis of osteomyelitis and may be useful to clinicians in differential diagnosis. A 26-year-old male patient presented to the emergency department with complaints of pain and limping in the right knee that did not go away. He had a history of arthroscopic debridement and percutaneous fixation surgery due to osteochondral fragment 3 years ago. There were no additional findings in the patient's vital parameters, physical examination, and medical history. X-ray imaging revealed two screws in the distal femur and a well-defined sclerotic rim surrounding a radiolucent lesion anterior to the screws. MRI revealed a lesion in the distal femoral metaphysis with low-density fluid and hyperintense granulation tissue surrounding it. After surgical abscess drainage and local debridement, bone cement was placed in the resulting cavity. Teicoplanin treatment was started. The patient was discharged and complete recovery was achieved in the second month. The diagnosis of osteomyelitis is often missed or confused with bone tumors in non-traumatic cases presenting with persistent bone pain. MRI imaging is frequently used in differential diagnosis, and detection of characteristic imaging signs such as the penumbra sign accelerates the diagnosis. In this context, emergency department clinicians, in particular, should be cautious and not forget that early treatment can be started by recognizing these signs.

Percepción sobre la formación en cuidados paliativos de los estudiantes de las especializaciones de Cirugía general en Colombia / Perception of palliative care training among students of General Surgery specializations in Colombia

Introducción. Los cuidados paliativos responden al sufrimiento de pacientes terminales y requieren personal entrenado para la intervención. Forman parte de la actividad en cirugía, sin embargo, no encontramos información sobre la educación de postgrado en cirugía en Colombia. El objetivo de este estudio fue evaluar el nivel de conocimientos en cuidados paliativos, la calidad de la formación y las estrategias pedagógicas en los residentes. Métodos. Estudio observacional con recolección de la información autodiligenciada por medio electrónico. Resultados. Participaron 228 residentes, 7,8 % mencionaron asistir a rotación en cuidado paliativo y 66,6 % tener contacto con especialistas en cuidados paliativos. El 30,7 % no identificó una estrategia pedagógica clara. El 29,3 % tuvo alto nivel de conocimiento y 21,1 % adecuada calidad de formación. El 83,8 % tuvo un alto nivel en el manejo de obstrucción intestinal. No hubo asociación entre el nivel de conocimiento y las variables evaluadas (p>0,05). Conclusiones. Ni el aprendizaje recibido, ni el año de entrenamiento tuvieron efecto en el nivel percibido de conocimiento. Las competencias en cuidados paliativos, sus métodos y la calidad del aprendizaje son deficientes a nivel de postgrado en cirugía en Colombia. Probablemente está en un currículo oculto. Es necesario implementar estrategias pedagógicas en los currículos de estudios de los programas de formación de cirujanos.

Introduction. Palliative care responds to the suffering of terminal patients and requires trained personnel for intervention. They are part of the activity in surgery; however, we did not find information about postgraduate education in surgery in Colombia. The objective of this study was to evaluate the level of knowledge in palliative care, the quality of training and pedagogical strategies in residents. Methods. Observational study with self-completed information collection by electronic means. Results. A total of 228 residents participated, 7.8% mentioned a palliative care rotation and 66.6% mentioned having contact with palliative care specialists; 30.7% did not identify a clear pedagogical strategy; 29.3% had a high level of knowledge and 21.1% had adequate quality of training; 83.8% had a high level in the management of intestinal obstruction. There was no association between the level of knowledge and the variables evaluated (p>0.05). Conclusions. Neither the learning received nor the year of training had an effect on the perceived level of knowledge. Competencies in palliative care, its methods and the quality of learning are deficient at the postgraduate level in surgery in Colombia. It is probably on a hidden resume. It is necessary to implement pedagogical strategies in the study curricula of surgeon training programs.

Temporal evolution of postsurgical bone repair in a rabbit model: A [99mTc]Tc-MDP scintigraphic study

Abstract Bone regeneration is crucial for repairing bone tissue following various injuries. Research techniques that enable the study of metabolic changes in bone tissue under different conditions are important for understanding bone repair and remodeling. This study used bone scintigraphy to evaluate osteogenesis secondary to osteotomy in a preclinical model of New Zealand rabbits. For this purpose, we conducted a longitudinal, prospective, case-control study in which scintigraphic variables were measured in both the right forearm (case-operated) and the left forearm (control - non-operated). The study sample consisted of 10 rabbits subjected to osteotomy, followed by a 12-week postoperative evaluation period, divided into six imaging stages at 1, 2, 3, 4, 8, and 12 weeks. We observed that the operated forearm showed significantly higher external radiation than the control side, using the pinhole collimator, denoting an increase in the biodistribution and tropism of the radiopharmaceutical to the operated forearm. Among the three evaluated time points, osteoblastic activity was highest in the second week and presented a significant decline in the 8th and 12th weeks, denoting regeneration and resolution of the surgical injury; the control forearm was also influenced by the inactivity imposed by the operated forearm. This fact was notably evidenced by the reduction in the metabolic activity of osteoblasts in the left forearm. Our study suggested that bone scintigraphy was sensitive enough to semi-quantitatively differentiate the metabolic activity of osteoblasts in the operated forearm in the three temporal landmarks evaluated in the study.

Introduction. The general surgeon training curriculum requires precision, contextual fit, and feasibility. In 2022, the World Society of Emergency Surgery formulated five statements on training in emergency minimally invasive digestive surgery, which can contribute to these purposes. This article examines the scope of these declarations for surgical education in Colombia. Methods. The scope and limitations for Colombia of each of the statements of the World Society of Emergency Surgery were analysed from a critical and reflective position, based on empirical evidence published during the last two decades in national and international indexed journals. Results. The empirical evidence produced in Colombia during this century allows us to identify that the country has the foundations of the national curriculum in general surgery, formulated by the Education Division of the Colombian Association of Surgery in 2021; a higher education accreditation system; a universal health insurance model; technological infrastructure, and institutional conditions that can facilitate the successful adoption of said statements for the training of future surgeons in emergency minimally invasive digestive surgery. However, its implementation requires greater efforts and investment in surgical simulation, institutional cooperation, and strengthening of the professional recertification system. Conclusion. Colombian surgical education is able to comply with the declarations of the World Society of Emergency Surgery regarding training in emergency minimally invasive digestive surgery.

El verdadero origen histórico del trauma cardíaco penetrante / The true historical origin of penetrating cardiac trauma

Introducción. Los traumatismos cardíacos son lesiones graves y con elevado índice de letalidad, aspecto que influye en el interés mostrado por los lectores cada vez que aparecen reportados en publicaciones científicas. En ocasiones existe cierto grado de incongruencia a la hora de establecer el origen histórico de sucesos o eventos ocurridos y relacionados con la historia de la medicina. En el caso del trauma cardíaco penetrante han sido descritos diversos orígenes en algunos de los artículos científicos publicados, lo cual puede generar un grado de duda en los lectores. Métodos. Se realizó una revisión de la literatura, médica y no médica, para buscar información que ayudara a esclarecer el verdadero origen histórico de esta entidad. Resultados. El trauma cardíaco penetrante fue descrito por primera vez en la obra griega titulada La Ilíada, escrita por Homero en el siglo VIII A.C., y no en El papiro quirúrgico de Edwin Smith, como varios autores mencionan. Conclusiones. De todos los eventos de trauma cardíaco penetrante descritos, el más irrefutable es el narrado en el canto XIII, donde se cuenta la muerte de Alcátoo, producto de una herida cardíaca ocasionada por una lanza arrojada por Idomeneo durante una batalla

Introduction. Cardiac traumatic injuries are serious injuries with a high lethality rate, an aspect that influences the interest shown by readers each time they appear reported in scientific publications. Sometimes there is a certain degree of inconsistency when it comes to establishing the historical origin of occurrences or events related to the history of medicine. In the case of penetrating cardiac trauma, different origins have been described in some of the published scientific articles, which may generate a degree of doubt in the readers. Methods. A review of the medical and non-medical literature was carried out to seek information that would help to clarify the true historical origin of this entity. Results. Penetrating cardiac trauma was first described in a Greek work entitled The Iliad, written by Homer in the 8th century B.C., and not in The Surgical Papyrus of Edwin Smith as several authors mention. Conclusions. Of all the events of penetrating cardiac trauma described, the most irrefutable is the one narrated in canto XIII, where it recounts the death of Alcathous product of a cardiac wound caused by a spear thrown by Idomeneo during a battle.

Abstract Background In 2012, the Neurocritical Care Society launched a compilation of protocols regarding the core issues that should be addressed within the first hours of neurological emergencies - the Emergency neurological life support (ENLS). Objective We aim to evaluate this repercussion through a bibliometric analysis. Methods We searched Scopus on October 2022 for articles mentioning ENLS. The following variables were obtained: number of citations; number of citations per year; number of publications per year; year of publication; research type; research subtype; country of corresponding author and its income category and world region; journal of publication and its 5-year impact factor (IF); and section where ENLS appeared. Results After applying eligibility criteria, we retrieved 421 articles, published from 2012 to 2022. The mean number of citations per article was 17.46 (95% Confidence Interval (CI) = 8.20-26.72), while the mean number of citations per year per article was 4.05 (95% CI = 2.50-5.61). The mean destiny journal 5-year IF was 5.141 (95% CI = 4.189-6.093). The majority of articles were secondary research (57.48%; n= 242/421) of which most were narrative reviews (71.90%; n= 174/242). High-Income countries were the most prominent (80.05%; n= 337/421 articles). There were no papers from low-income countries. There were no trials or systematic reviews from middle-income countries. Conclusion Although still low, the number of publications mentioning ENLS is increasing. Articles were mainly published in journals of intensive care medicine, neurology, neurosurgery, and emergency medicine. Most articles were published by authors from high-income countries. The majority of papers were secondary research, with narrative review as the most frequent subtype.

Conclusão Embora ofereçam benefícios holísticos, estas terapias devem ser consideradas com cautela devido ao apoio científico limitado e às potenciais interações. A compreensão cultural, o diálogo paciente-prove-dor e as escolhas informadas são fundamentais para aproveitar o potencial da medicina alternativa juntamente às abordagens convencionais para gerir os desafios da COVID-19.

Gênero e sexualidade no currículo médico: a perspectiva de professories de um curso de graduação em Medicina / Gender and sexuality in medical curriculums: the perspective of teachers on a medical degree program / Género y sexualidad en el currículo médico: la perspectiva de profesores de un curso de graduación en medicina

O conhecimento e o desenvolvimento de habilidades relacionadas à abordagem de gênero na formação médica são fundamentais para o exercício do cuidado integral. Enfocamos o ensino dos temas gênero e sexualidade na graduação de um curso de Medicina sob a perspectiva docente. A pesquisa de natureza qualitativa utilizou a entrevista semiestruturada para construção dos dados empíricos. Em 2022, foram realizadas 16 entrevistas com responsáveis por disciplinas/unidades curriculares de diversas especialidades médicas de um curso de graduação em Medicina no estado de São Paulo. Apesar do reconhecimento da importância na formação, vigora ainda uma abordagem biomédica e/ou patológica das temáticas de gênero e sexualidade no currículo. Como dificuldades, destaca-se o reconhecimento da questão geracional pela falta de habilidade para lidar com os temas e a pouca interação entre especialidades médicas.

Including the development of knowledge and skills related to the gender approach in medical training is essential for the delivery of comprehensive care. This study focuses on the teaching of gender and sexuality on a medical degree program from the perspective of teachers. We conducted a qualitative study using semi-structured interviews to collect empirical data. Sixteen interviews were conducted in 2022 with teachers responsible for subjects/modules in medical specialties on a medical degree program in the state of São Paulo. Despite the recognition given to the importance of teaching gender and sexuality in medical training, a biomedical and/or disease-based approach to these topics prevails in the curriculum. Challenges include generational issues, including the lack of skills needed to deal with these topics, and limited interaction between medical specialties.

En 2022, se realizaron dieciséis (16) entrevistas con responsables por disciplinas/unidades curriculares de diversas especialidades médicas de un curso de graduación en medicina en el Estado de São Paulo. A pesar del reconocimiento de la importancia en la formación, vigora todavía un abordaje biomédico y/o patológico de las temáticas de género y sexualidad en el currículo. Como dificultad se destaca el reconocimiento de la cuestión generacional por la falta de habilidad para enfrentar los temas y la poca interacción entre especialidades médicas.

O racismo e o sexismo na trajetória das estudantes de Medicina negras: uma revisão integrativa / El racismo y el sexismo en la trayectoria de las estudiantes de medicina negras: una revisión integradora / Racism and sexism in the trajectory of black female medical students: an integrative review

Alunas negras do curso de Medicina são minoria e enfrentam diversos obstáculos durante a formação por serem mulheres negras. Objetivou-se sintetizar o conhecimento produzido em estudos empíricos sobre a discriminação racial e de gênero que sofrem estudantes de Medicina negras no curso. Realizamos uma revisão integrativa nas bases de dados do PubMed e BVS. Foram analisados em profundidade cinquenta estudos classificados em três categorias temáticas: I- O preconceito racial sistêmico-estrutural e estruturante; II- O racismo como um dos fatores da iniquidade na educação médica; e III- O racismo genderizado vivenciado pelas estudantes negras. Concluiu-se que, nas escolas médicas, um espaço social com baixa diversidade étnica/racial e atravessado pelo racismo estrutural, as estudantes negras são discriminadas pela intersecção das dinâmicas de raça, gênero e classe social.

Las alumnas negras del curso de medicina son minoría y enfrentan diversos obstáculos durante la formación por ser mujeres negras. El objetivo fue sintetizar el conocimiento producido en estudios empíricos sobre la discriminación racial y de género que sufren estudiantes de medicina negras en el curso. Realizamos una revisión integradora de las bases de datos del PubMed y BVS. Se analizaron en profundidad cincuenta estudios clasificados en tres categorías temáticas: 1- El prejuicio racial sistémico-estructural y estructurador. 2- El racismo como uno de los factores de la inequidad en la Educación Médica. 3- El racismo de género vivido por las estudiantes negras. Se concluyó que, en las escuelas médicas, un espacio social con baja diversidad étnica/racial, atravesado por el racismo estructural, las estudiantes negras son discriminadas por la intersección de las dinámicas de raza, género y clase social.

Black female medical students are a minority and face various obstacles during their training because they are black women. The study aimed to synthesize the knowledge produced in empirical studies on the racial and gender discrimination suffered by black female medical students. We carried out an integrative review using the PubMed and VHL databases. Fifty studies were analyzed in depth and classified into three thematic categories: 1- Systemic-structural and structuring racial prejudice. 2- Racism as one of the factors of inequity in medical education. 3- Genderized racism experienced by black students. It was concluded that in medical schools, a social space with low ethnic/racial diversity and crossed by structural racism, female black students are negatively discriminated by the intersection of race, gender and social class dynamics.

Bacterial coinfections in COVID-19-hospitalized patients

SUMMARY OBJECTIVE: The aim of this study was to assess the rate of bacterial infections in COVID-19-hospitalized patients and to analyze the most prevalent germs, sources, risk factors, and its impact on in-hospital mortality. METHODS: This observational retrospective study was conducted on 672 patients hospitalized between April and August 2020 in Nossa Senhora da Conceição Hospital, a public hospital located in Porto Alegre, Brazil. The inclusion criterion was adult patients hospitalized with confirmed COVID-19. Data were collected through chart review. Risk factors for bacterial infection and mortality were analyzed using both univariate and multivariate robust Poisson regression models. RESULTS: Bacterial coinfection was observed in 22.2% of patients. Risk factors for bacterial infections were dementia (RR=2.06 (1.18-3.60); p=0.011), cerebrovascular disease (RR=1.75 (1.15-2.67); p=0.009), active cancer (RR=1.52 (1.082-2.15); p=0.01), need for noninvasive ventilation (RR=2.320 (1.740-3.094); p<0.01), invasive mechanical ventilation (RR=4.63 (2.24-9.56); p<0.01), and renal replacement therapy (RR=1.68 (1.26-2.25); p<0.01). In the adjusted model, bacterial infections were not associated with mortality (0.96 (0.75-1.24); p=0.79). The most common source of infection was due to respiratory, blood, and central venous catheters, with 69 (29.36%), 61 (25.96%), and 59 (25.11%) positive cultures, respectively. CONCLUSION: We observed a high rate of bacterial infections in COVID-19-hospitalized patients, most commonly of respiratory source. Neurologic and oncologic morbidities and need for ventilation and renal replacement therapy was associated with risk factors for bacterial infections. Nevertheless, an association between bacterial infections and hospital mortality was not established.

Transfusion of packed red blood cells in adults with sickle cell anemia treated at an emergency hospital

SUMMARY OBJECTIVE: The aim of this study was to analyze the prescription of packed red blood cells performed by emergency physicians for adults with sickle cell anemia. METHODS: Transfusions performed in adults with sickle cell anemia treated at an emergency service in São Bernardo do Campo, São Paulo Brazil, between January 2018 and January 2022 were evaluated. For data comparison, the chi-square2 test was used. The significance level adopted was 5%. RESULTS: A total of 114 transfusions were performed. The mean age was 41.8±16.4 years, and pretransfusion hemoglobin was 6.1±1.23 g/dL. Regarding the indication, the adequacy of transfusions performed in symptomatic individuals was significantly higher compared to asymptomatic individuals (100% vs. 3.9%, p<0.001). Symptomatic individuals received excessive volumes of packed red blood cells less frequently than asymptomatic individuals (17.5% vs. 56.9%, p<0.001). The filtered subtype, indicated for sickle cell anemia, was prescribed in only a quarter of the patients. However, non-indicated subtypes were frequently prescribed. CONCLUSION: This study found low adequacy in the indication and calculation of the transfusion volume of packed red blood cells in asymptomatic individuals. Few patients received filtered red blood cells, resulting in increased risks of transfusion reactions. On the contrary, non-indicated subtypes were prescribed in a quarter of transfusions, which resulted in higher costs and delay in receiving packed red blood cells.

Modelos de preceptoria de residência em medicina de família e comunidade: um estudo Delphi / Models of preceptorship in family and community medicine residence: a Delphi study

Resumo Introdução: A preceptoria na atenção primária à saúde desempenha papel central na formação do residente, já que 70%-80% da carga horária dos programas de residência de medicina de família e comunidade (PRMFC) acontece na unidade de saúde da família. Como preceptor entende-se o professor que ensina na prática clínica. O cenário atual de expansão dos PRMFC, associado a poucos profissionais especializados em preceptoria, fez com que vários modelos fossem praticados. Uma revisão de literatura feita em estágio anterior a este trabalho, além das contribuições da Sociedade Brasileira de Medicina de Família e Comunidade, identificou quatro modelos de preceptoria em MFC: ombro a ombro, preceptor da equipe ao lado, preceptor de unidade e preceptor de campo. Objetivo: Este estudo teve como objetivos validar esses quatro modelos e identificar outros, determinar, sob a ótica da qualidade de formação dos residentes, a aceitabilidade e o grau de recomendação dos modelos, e reconhecer os pontos positivos e negativos. Método: Utilizou-se a técnica Delphi modificada por questionários on-line. O estudo começou com 24 participantes de todo o Brasil na primeira rodada e terminou com 18. Aplicaram-se a técnica de estatística descritiva e a análise de conteúdo. O estudo foi realizado entre fevereiro e abril de 2022. Resultado: Validaram-se os quatro modelos apresentados, e nenhum outro foi identificado. Os modelos ombro a ombro, preceptor da equipe ao lado e preceptor de unidade foram considerados aceitáveis; e o modelo preceptor de campo, inaceitável. Os modelos ombro a ombro e preceptor de unidade foram recomendados. Reconheceram-se 92 aspectos como pontos positivos e negativos, dos quais 81 atingiram consenso. Conclusão: Obteve-se a validação dos quatro tipos de modelos de preceptoria para PRMFC. Como os modelos ombro a ombro e preceptor de unidade foram elencados como aceitáveis e recomendáveis, é importante que sejam priorizados na implantação e manutenção dos PRMFC. Os modelos preceptor da equipe ao lado e preceptor de campo foram julgados como não recomendados e, portanto, devem ser evitados. O conhecimento das fortalezas e fraquezas de cada modelo prepara os PRMFC para as possíveis dificuldades e os auxilia na escolha do modelo adequado às diversas realidades existentes no país.

Abstract Introduction: Medical residency preceptorship in primary healthcare plays a major role in the professional qualification of medical residents, since 70-80% of the workload of the Family and Community Medical Residency Program (PRMFC) takes place in primary care clinics. A preceptor is understood as an experienced practitioner who teaches during clinical practice. The current scenario of expansion of PRMFCs in Brazil, associated with the limited number of professionals specialized in preceptorship, has resulted in the practice of different preceptorship models. A literature review performed in the previous stage of this study, added to the contributions of the Brazilian Society of Family and Community Medicine, pointed out four models of preceptorship in family practice: shoulder-to-shoulder, next-door team, clinic preceptor and field preceptor. Objective: To validate these four models of preceptorship and identify if there are others models; to determine, from the perspective of the quality of training residents, the acceptability and degree of recommendation of the models and recognize the positive and negative points. Method: The Delphi technique modified by online questionnaires was used. It was initiated with 24 participants from all over Brazil in the first round and ended with 18. Descriptive statistics and content analysis method was applied. The study was conducted between February and April 2022. Result: The four models presented were validated and no others were identified. The shoulder-to-shoulder, nextdoor team preceptor and clinic preceptor models were considered acceptable and the field preceptor model, unacceptable. The shoulder-to-shoulder and clinic preceptor models were recommended. Ninety-two aspects were recognized as positive and negative points. Of these, 81 achieved consensus. Conclusion: The shoulder-to-shoulder preceptor and clinic preceptor models were validated as acceptable and recommended, so it is important to prioritize these models in the implementation and maintenance of PRMFCs. The next-door team preceptor and field preceptor models were deemed as not recommended and, therefore, should be avoided. Information about the strengths and weaknesses of each model prepares the PRMFCs for possible implementation difficulties and helps them to select the appropriate model for the different realities existing in the country.

Medicina e espiritualidade: o perfil de estudantes e médicos de uma escola médica brasileira / Medicine and spirituality: the profile of students and physicians at a Brazilian medical school

Resumo Introdução: Pesquisas científicas indicam que a espiritualidade desempenha um papel importante na vida da maioria dos pacientes. Além disso, atividades e crenças religiosas podem, de acordo com algumas pesquisa, estar relacionadas à melhor saúde e qualidade de vida1. Objetivo: Este estudo teve como objetivos avaliar o nível de espiritualidade de estudantes de Medicina e de médicos já formados, e analisar o ensino da interface "medicina e espiritualidade" na escola médica. Método: Realizamos um estudo transversal descritivo por meio da aplicação de questionários a estudantes de Medicina e médicos de uma escola médica pública brasileira. Resultado: Avaliaram-se 234 participantes. A maioria acredita em uma força superior. A espiritualidade foi maior entre médicos já formados e entre pessoas do sexo feminino. A maioria acredita que a formação universitária não prepara o médico para abordar o tema com os pacientes. Apesar dessa limitação, a maioria já abordou a espiritualidade com seus pacientes. Conclusão: Médicos e estudantes de Medicina consideram importante contemplar, de maneira ecumênica e respeitosa, aspectos espirituais dos pacientes. Apesar disso, consideram que não receberam preparo suficiente na escola médica para essa abordagem.

Abstract Introduction: Scientific research indicates that spirituality plays an important role in the daily life of most patients. Moreover, there are studies indicating that religious activities and beliefs may be related to better health and quality of life1. Objective: to evaluate the level of spirituality of medical students and graduated physicians, in addition to analyzing the teaching of the "Medicine and Spirituality" interface in medical school. Methodology: A descriptive cross-sectional study was carried out by applying questionnaires to medical students and doctors at a Brazilian public medical school. Results: a total of 234 participants were evaluated. Most believe in a higher power. Spirituality was higher among doctors who had already graduated and among females. Most believe that university education does not prepare doctors to address the topic with the patients. Despite this limitation, most have already discussed spirituality with their patients. Conclusion: Doctors and medical students consider it important to contemplate spiritual aspects of patients using an ecumenical and respectful approach. Nevertheless, they consider they were not sufficiently prepared in medical school for this approach.

Variability in the perception of palliative care and end-of-life care among hematology professionals from the same reference center in Bahia, Brazil: A descriptive cross-sectional study

ABSTRACT BACKGROUND: There are several illness-specific cultural and system-based barriers to palliative care (PC) integration and end-of-life (EOL) care in the field of oncohematology. OBJECTIVES: This study aimed to investigate the variability in the perceptions of PC and EOL care. DESIGN AND SETTING: A cross-sectional study was conducted in the Hematology Division of our University Hospital in Salvador, Bahia, Brazil. METHODS: Twenty physicians responded to a sociodemographic questionnaire and an adaptation of clinical questionnaires used in previous studies from October to December 2022. RESULTS: The median age of the participants was 44 years, 80% of the participants identified as female, and 75% were hematologists. Participants faced a hypothetical scenario involving the treatment of a 65-year-old female with a poor prognosis acute myeloid leukemia refractory to first-line treatment. Sixty percent of the participants chose to follow other chemotherapy regimens, whereas 40% opted for PC. Next, participants considered case salvage for the patient who developed septic shock following chemotherapy and were prompted to choose their most probable conduct, and the conduct they thought would be better for the patient. Even though participants were from the same center, we found a divergence from the most probable conduct among 40% of the participants, which was due to personal convictions, legal aspects, and other physicians' reactions. CONCLUSIONS: We found considerable differences in the perception of PC and EOL care among professionals, despite following the same protocols. The study also demonstrated variations between healthcare professionals' beliefs and practices and persistent historical tendencies to prioritize aggressive interventions.

Transtorno do espectro do autismo e o uso materno e paterno de medicamentos, tabaco, álcool e drogas ilícitas / Maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder

Resumo O presente estudo objetivou investigar a associação entre o TEA e o uso materno e paterno de medicamentos, tabaco, álcool e drogas ilícitas. Trata-se de um estudo caso-controle realizado com crianças e adolescentes diagnosticados com TEA e indivíduos neurotípicos. Os dados foram colhidos por meio de entrevista com as mães ou responsáveis. Foram analisadas as variáveis sexo e idade das crianças/adolescentes; idade dos pais; uso de medicamentos antes e durante a gestação; classes de medicamentos usados na gestação; tabagismo materno e paterno; etilismo materno e paterno; uso de drogas ilícitas pelos pais. Para a análise das informações, utilizou-se o modelo de regressão logística, além da razão de chances (OR) bruta e ajustada. Os resultados mostraram que, após os ajustes, foi encontrada associação entre o uso materno na gestação de antitérmicos/analgésicos (OR = 2,26; IC95% 1,29-3,95; p < 0,040) com o TEA. Já o uso de tabaco, álcool e drogas ilícitas materno e paterno, antes e durante a gestação, não apontou relação com o TEA. Os dados encontrados sugerem que existe influência de fatores ambientais no desenvolvimento do TEA.

Abstract The aim of this study was to investigate the association between maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder (ASD). We conducted a case-control study with children and adolescents diagnosed with ASD and neurotypical individuals. The data were collected using a semi-structured questionnaire administered during interviews with the children's mothers or guardians. The following variables were analyzed: child sex and age; maternal and parental age; use of medicines before and during pregnancy; classes of medicines used during pregnancy; maternal and paternal smoking; maternal and paternal drinking; maternal and paternal illicit drug use. The data were analyzed using logistic regression and crude and adjusted odds ratios (OR). After adjustment, the results showed an association between maternal use of antipyretics/pain killers during pregnancy (OR = 2.26; 95%CI 1.29-3.95; p < 0.040) and ASD. No association was found between maternal and paternal smoking, drinking and illicit drug use before and during pregnancy and ASD. The findings suggest that the development of ASD is influenced by environmental factors.
