ChatGPT's learning and reasoning capacity in anesthesiology

Introduction: Over the past few months, ChatGPT has raised a lot of interest given its ability to perform complex tasks through natural language and conversation. However, its use in clinical decision-making is limited and its application in the field of anesthesiology is unknown. Objective: To assess ChatGPT's basic and clinical reasoning and its learning ability in a performance test on general and specific anesthesia topics. Methods: A three-phase assessment was conducted. Basic knowledge of anesthesia was assessed in the first phase, followed by a review of difficult airway management and, finally, measurement of decision-making ability in ten clinical cases. The second and the third phases were conducted before and after feeding ChatGPT with the 2022 guidelines of the American Society of Anesthesiologists on difficult airway management. Results: On average, ChatGPT succeded 65% of the time in the first phase and 48% of the time in the second phase. Agreement in clinical cases was 20%, with 90% relevance and 10% error rate. After learning, ChatGPT improved in the second phase, and was correct 59% of the time, with agreement in clinical cases also increasing to 40%. Conclusions: ChatGPT showed acceptable accuracy in the basic knowledge test, high relevance in the management of specific difficult airway clinical cases, and the ability to improve after learning.

Initial nipple damages in breastfeeding women: analysis of photographic images and clinical associations / Lesiones tempranas del pezón derivadas de la lactancia materna: análisis de imágenes fotográficas y asociaciones clínicas / Lesões mamilares precoces decorrentes da amamentação: análise de imagens fotográficas e associações clínicas

ABSTRACT Objective: to analyze the initial nipple damage degree by breastfeeding practice and to associate findings with clinical manifestations of breastfeeding women. Methods: a retrospective, cross-sectional study with primary data and photographic images database from two randomized clinical trials. Photographic images were analyzed by two independent evaluators using the Nipple Trauma Score. For analysis, the chi-square, Mann-Whitney tests and Kappa coefficient were applied. Results: 115 breastfeeding women and their respective 186 photographic images were analyzed. The degree of agreement of evaluators using the Nipple Trauma Score was 93.6%. The nipple pain score during breastfeeding was moderate and compromised more than 25% of the nipple surface area. Conclusions: assistance to breastfeeding women should prioritize nipple pain intensity instead of the nipple damage size.

Portuguese Advance Directives-a twist against futility? A cross sectional study

ABSTRACT BACKGROUND: Advance Directive documents allow citizens to choose the treatments they want for end-of-life care without considering therapeutic futility. OBJECTIVES: To analyze patients' and caregivers' answers to Advance Directives and understand their expectations regarding their decisions. DESIGN AND SETTING: This study analyzed participants' answers to a previously published trial, conceived to test the document's efficacy as a communication tool. METHODS: Sixty palliative patients and 60 caregivers (n = 120) registered their preferences in the Advance Directive document and expressed their expectations regarding whether to receive the chosen treatments. RESULTS: In the patient and caregiver groups, 30% and 23.3% wanted to receive cardiorespiratory resuscitation; 23.3% and 25% wanted to receive artificial organ support; and 40% and 35% chose to receive artificial feeding and hydration, respectively. The participants ignored the concept of therapeutic futility and expected to receive invasive treatments. The concept of therapeutic futility should be addressed and discussed with both the patients and caregivers. Legal Advanced Directive documents should be made clear to reduce misinterpretations and potential legal conflicts. CONCLUSION: The authors suggest that all citizens should be clarified regarding the futility concept before filling out the Advance Directives and propose a grammatical change in the document, replacing the phrase "Health Care to Receive / Not to Receive" with the sentence "Health Care to Accept / Refuse" so that patients cannot demand treatments, but instead accept or refuse the proposed therapeutic plans.

A tomada de decisão no tratamento de crianças com indicadores de TDAH / Toma de decisiones en el tratamiento de niños con indicadores de TDAH / Decision making in the treatment of children with ADHD indicators

RESUMO O diagnóstico de Transtorno de Déficit de Atenção e Hiperatividade - TDAH é bastante complexo, podendo ser influenciado por fatores contextuais, e seu tratamento pode envolver diferentes intervenções. A participação dos usuários nas decisões a respeito do tratamento vem sendo promovida por instituições de diversos países e, no Brasil, é prevista pelas legislações do Sistema Único de Saúde. Este estudo investigou o processo de tomada de decisão no tratamento de crianças com indicadores de TDAH a partir da percepção de oito profissionais de serviços públicos de saúde mental, que foram entrevistados individualmente. Os dados foram examinados através da análise temática, revelando desafios relativos ao excesso de demanda nos serviços e à complexidade do processo diagnóstico. O envolvimento de usuários e familiares nas decisões foi percebido como parcial, ocorrendo geralmente após a elaboração do plano terapêutico pelas equipes, e envolvendo dificuldades na comunicação entre profissionais e pacientes e divergências de interesses entre as crianças e seus familiares. Esses aspectos poderão ser abordados em futuros estudos e intervenções a fim de facilitar e melhorar a qualidade da tomada de decisão nesse contexto.

ABSTRACT The diagnosis of Attention Deficit Hyperactivity Disorder - ADHD is quite complex. Contextual factors may influence it, and its treatment may involve different interventions. Institutions in several countries have promoted the participation of users in treatment decisions. In Brazil, it is provided by the Unified Health System. This study investigated the decision-making process in treating children with ADHD indicators from the perception of 8 public mental health services professionals interviewed individually. Data were examined through thematic analysis, revealing challenges related to excessive demand for services and the complexity of the diagnostic process. The involvement of users and family members in the decisions was perceived as partial, generally occurring after elaborating the therapeutic plan by the teams, and involving difficulties in communication between professionals and patients and differences of interests between children and their families. These aspects may be addressed in future studies and interventions to facilitate and improve the quality of the decision-making process in this context.

Exploration of Decision-Making Methods Based on Syndrome Differentiation by “Data-Knowledge” Dual-Driven Models： A Case Study of Gastric Precancerous State / 中医杂志

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

El pediatra y los padres en la toma de decisiones de tratamiento en plagiocefalia posicional: una revisión narrativa / The pediatrician and parents in treatment decision-making in positional plagiocephaly: A narrative review

La plagiocefalia posicional (PP) es una de las causas más frecuentes de consulta en neurocirugía pediátrica. La incidencia de PP aumentó en los '90, a partir de la campaña Dormir de espaldas. Junto con el aumento de la demanda de atención, se verifica un debate acerca de la eficacia de los distintos tratamientos. La interacción padres ­ pediatra orientada a elegir la mejor terapéutica adquiere importancia, particularmente cuando se trata de decisiones sensibles a la preferencia. Es necesario saber más acerca de la naturaleza de la toma de decisiones de tratamiento de PP, para contribuir al desarrollo de procesos decisorios eficaces. Se realizó una revisión narrativa sobre investigaciones en toma de decisiones de tratamiento en PP. Se identificaron artículos en PubMed y Google Scholar (1990 ­ 2022) en una búsqueda con los descriptores "plagiocephaly", "decision making" y "parents". Se incluyeron artículos cuyo tema central fuera la toma de decisiones en PP, o que la desarrollaran como parte de otro tema. Se excluyeron trabajos en los que la toma de decisiones aparece de modo secundario o tangencial. Se encontraron 3 artículos con distintos diseños metodológicos, en los que la severidad de la presentación, los elementos socioculturales y emocionales, y los aspectos relacionados con el tratamiento son los factores más implicados en la toma de decisiones. Las relaciones entre la ansiedad parental, las expectativas de tratamiento y la percepción subjetiva de la PP, y el rol del pediatra como proveedor de información válida y confiable son temas que necesitan de ulterior investigación (AU)

Positional plagiocephaly (PP) is one of the main reasons for consultation in pediatric neurosurgery. The incidence of PP increased in the 1990s, after the "Back to Sleep" campaign. Concurrently, the growing demand for care has led to a debate regarding the effectiveness of the different treatments. The parent-pediatrician interaction is aimed at choosing the best therapeutic approach becomes important, particularly when it comes to preference-sensitive decisions. There is a need to better understand the nature of PP treatment decision-making in order to contribute to the development of effective decisionmaking processes. In this narrative review, we evaluated the research on treatment decision-making in PP. Articles were identified in PubMed and Google Scholar (1990 - 2022) using the search terms "plagiocephaly", "decision-making" and "parents". Articles were included if their central theme was decision-making in PP, or if they developed it as part of another subject. We excluded articles in which decision-making appeared in a secondary or tangential way. Three articles were identified with different methodological designs, in which the severity of the presentation, sociocultural and emotional aspects, and aspects related to treatment were the factors most implicated in decision making. The relationships between parental anxiety, treatment expectations, subjective perception of PP, and the role of the pediatrician as a provider of valuable and reliable information are topics that require further investigation (AU)

Patients´ satisfaction concerning direct anterior dental restoration

Abstract The objective of this study was to observe patients' satisfaction with their in-service direct anterior dental restorations and to compare it with clinical evaluation using FDI (Federation Dental International) criteria. Patients scored their own anterior dental restorations regarding satisfaction (satisfactory /dissatisfactory). If dissatisfaction was mentioned, then, they would be interviewed about the complaint. In the same session, the dental restorations were clinically evaluated by two dentists using FDI criteria (1-5 score) concerning esthetic, functional, and biological domains. Descriptive statistics were used for frequencies of scores attributed by patients and clinicians. In order to compare patients' to clinicians' frequencies, the Chi-square test was applied (p ≤ 0.05). A total of 106 restorations were evaluated by patients and clinicians. Patients reported 52.8% of restorations satisfactory and 47.8% dissatisfactory. Overall, clinicians reported the same restorations as 82,3% satisfactory and 17,6% dissatisfactory. Patients' most frequent complaints referred to color, followed by anatomical form, fracture of material and retention, and approximal anatomical form. Comparing patients' satisfaction and dissatisfaction rates to clinicians' evaluation per criteria, there was no difference regarding esthetics. The frequency of dissatisfactory restorations by clinicians was significantly lower when functional and biological properties were compared with patients' opinions. Direct anterior dental restorations were more frequently reported as satisfactory by patients and clinicians, being the main complaints related to esthetic issues. When clinicians and patients' evaluations were compared, it was observed that the frequencies of satisfactory restoration by patients and clinicians were similar regarding esthetic properties, and significantly different regarding functional and biological properties.

Resumo O objetivo deste estudo foi observar a satisfação dos pacientes com suas restaurações dentárias anteriores diretas e compará-las com a avaliação clínica do dentista usando os critérios FDI (Federation Dental International). Os pacientes pontuaram suas restaurações dentárias (n=106) anteriores em relação à satisfação (satisfatória / insatisfatória). Quando insatisfatória, ele foi entrevistado sobre a queixa. Na mesma sessão, as restaurações dentárias foram avaliadas clinicamente por dois dentistas utilizando os critérios FDI (escore 1-5) quanto aos aspectos estéticos, funcionais e biológicos. Estatística descritiva foi usada para frequências de escores atribuídos por pacientes e clínicos. Para comparar as frequências dos pacientes e dos clínicos, foi aplicado o teste Qui-quadrado (p ≤ 0,05). Os pacientes relataram suas restaurações como 52,8% satisfatórias e 47,8% insatisfatórias. Os clínicos reportaram as mesmas restaurações, 82,3% satisfatória e 17,6% insatisfatória. As queixas mais frequentes dos pacientes referiam-se à cor, seguida da forma anatômica, fratura e retenção do material e forma anatômica proximal. Comparando os índices de satisfação e insatisfação dos pacientes com os clínicos, não houve diferença em relação à estética. A frequência de restaurações insatisfatórias por dentistas foi significativamente menor quando as propriedades funcionais e biológicas foram comparadas com as opiniões dos pacientes. As restaurações foram mais frequentemente relatadas como satisfatórias pelos pacientes, sendo as principais queixas relacionadas a questões estéticas. Quando as avaliações dos clínicos e dos pacientes foram comparadas, observou-se que as frequências de restaurações satisfatórias por pacientes e clínicos foram semelhantes em relação às propriedades estéticas e significativamente diferentes em relação às propriedades funcionais e biológicas.

Diseño de sistema basado en reglas para apoyar la toma de decisiones de la población en la obtención de los medicamentos

En Cuba, el acceso a los servicios farmacéuticos por parte de la población se ve afectado por la no disponibilidad de medicamentos y la lejanía de las farmacias. La falta de información acerca de la existencia de los medicamentos y la cantidad de estos en la red de farmacias cercanas a una ubicación geográfica, aparejados al poco suministro de medicamentos y la calidad de la prestación del servicio, genera descontento e inconformidad en la población. En la presente investigación se realiza un diseño para mejorar la problemática planteada a partir de un sistema basado en reglas como ayuda a la toma de decisiones para la obtención de los medicamentos por parte de la población. Se aplica un estudio de caso mediante el cual es posible sugerir al usuario las 5 farmacias más cercanas donde el paciente puede adquirir los medicamentos sobre las decisiones asumidas.

In Cuba, access to pharmaceutical services by the population is affected by the non-availability of medicines and the remoteness of pharmacies. The lack of information about the existence of medicines and the quantity of these in the network of pharmacies close to a geographical location, coupled with the low supply of medicines and the quality of service provision, generates discontent and nonconformity in the population. In the present investigation, a design is carried out to improve the problem raised from a system based on rules as an aid to decision-making to obtain medicines by the population. A case study is applied through which it is possible to suggest to the user the 5 closest pharmacies where the patient can acquire the medicines on the decisions made.

A Master Mind Game Code Algorithm Approach to Help Surgical Decision-Making between Retropharyngeal Fat Grafting and Pharyngoplasty for the Treatment of Velopharyngeal Incompetence

Abstract Introduction Velopharyngeal insufficiency (VPI) is a controversial pathology with many surgical options. Objectives To compare pharyngoplasty and retropharyngeal fat grafting and to build a prognostic tool to achieve perfect speech. Methods Retrospective observational cohort study of 114 patients operated for VPI from 1982 to 2019 in a single tertiary center. The instrumental assessment was made using an aerophonoscope and nasofibroscopy. The variables sex, age, genetic syndromes, and type of diagnosis were analyzed with logistic regression model adjusted with propensity score. To generalize results and to build a surgical predictive tool, a marginal analysis concludes the study. Results Among the patients (median [range] age 7 [4-48]), 63 (55.26%) underwent pharyngoplasty and 51 (44.74%) graft. The graft group had no complication, but it had a failure rate of 7.84%. The pharyngoplasty group had no failure, but one patient had postoperative obstructive sleep apnea. The marginal analysis demonstrated that age lower than 7 years, cleft lip and palate, absence of syndrome, and intermittent VPI were important predictive factors of good result regardless of surgical technique. Conclusions Without a statistical demonstration of the superiority of pharyngoplasty over graft, and in the uncertainty of literature background, our perfect-speech patient profile represents an important tool for a postoperative forecast of results in which, like in the Master Mind game, every feature has to be considered not individually but as a pattern of characteristics whose association contributes to the outcome.

Estratégias de ensino para desenvolvimento do pensamento crítico na graduação em enfermagem: overview de revisões sistemáticas / Educational strategies for development of clinical reasoning and critical thinking in nursing undergraduate students: overview protocol of systematic reviews

Resumo: O objetivo desta pesquisa foi sumarizar as evidências de revisões sistemáticas sobre a efetividade das estratégias de ensino para o desenvolvimento do raciocínio clínico ou pensamento crítico em estudantes da graduação em Enfermagem. Trata-se de uma overview de revisões sistemáticas, guiada pelas recomendações do Cochrane Handbook. O protocolo de pesquisa foi registrado na plataforma Prospero sob o número 187785, sendo este estudo inédito. O uso do protocolo possibilita a replicação ou atualização dessa overview. A pergunta de pesquisa foi: Quais as evidências de efetividade oriundas de revisões sistemáticas sobre as estratégias de ensino, isoladas, comparadas ou associadas, para o desenvolvimento do pensamento crítico dos estudantes de graduação em Enfermagem, em qualquer ambiente de aprendizagem? A busca por revisões Cochrane e não Cochrane foi realizada em oito bases de dados e bibliotecas, e na literatura cinzenta. Não houve restrições de idioma e ano de publicação. Foi recuperado um total de 13.936 estudos, com 6.620 participantes. Dois revisores independentes aplicaram os critérios de inclusão e exclusão, fizeram a extração dos dados e a análise de qualidade das revisões. Foram incluídas 11 revisões, com 65 estudos primários. As sínteses foram descritivas e por metanálises. A análise do risco de viés das revisões sistemáticas foi realizada por meio do instrumento ROBIS (Risk of Bias in Systematic Reviews); a qualidade metodológica foi avaliada pelo instrumento AMSTAR 2 (A MeaSurement Tool to Assess systematic Reviews); e a análise da força da evidência seguiu as recomendações do sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation). Quatorze estudos, com 1.350 participantes, forneceram evidências para metanálise. As evidências, ainda que classificadas como de certeza muito baixa, sugerem que a aprendizagem baseada em problemas e a simulação são estratégias de ensino que possibilitam o desenvolvimento do pensamento crítico em estudantes de graduação em enfermagem. Risco de viés, heterogeneidade elevada, número limitado de estudos, número de participantes reduzido contribuíram para o rebaixamento do nível de certeza das evidências. Recomenda-se que os docentes avaliem as características dos estudantes antes de optarem por uma ou outra estratégia de ensino, e ponderem o uso diversificado. São importantes a frequência e duração da aplicação das estratégias, uma vez que o desenvolvimento do pensamento crítico ocorre de forma processual e contínua. Recomenda-se aos pesquisadores que o relato seja aprimorado, incluindo informações relevantes, como dados estatísticos, características do estudante e do ambiente de ensino. O uso de ferramentas que orientem um relato de qualidade é indicado. No planejamento dos ensaios clínicos, é relevante prever e padronizar o tempo de exposição à estratégia de ensino e a quantidade de sessões; utilizar pelo menos duas escalas de mensuração do pensamento crítico e aplicá-las no mínimo antes e após a intervenção. Tais cuidados promovem robustez aos resultados. A contribuição social dessa tese inédita é a identificação de estratégias de ensino - aprendizagem baseada em problemas e simulação - eficazes para o desenvolvimento do pensamento crítico em estudantes de enfermagem, o que possibilita, consequentemente, aprimorar a qualificação dos futuros enfermeiros para a prática profissional segura e baseada em evidências.

Abstract: The aim of this study was to summarize evidence from systematic reviews on the effectiveness of teaching strategies for the development of clinical reasoning or critical thinking in undergraduate nursing students. This is an overview of systematic reviews guided by the Cochrane Handbook recommendations. The research protocol was registered on the Prospero platform under number 187785 and this study is unprecedented. The use of the protocol makes it possible to replicate or update this overview. The research question was: What is the evidence of effectiveness from systematic reviews on teaching strategies, isolated, compared or associated, for the development of critical thinking of undergraduate nursing students in any learning environment? The search for Cochrane and non-Cochrane reviews was performed in eight databases and libraries, and in the gray literature. There were no language and year of publication restrictions. A total of 13,936 studies with 6,620 participants were retrieved. Two independent reviewers applied inclusion and exclusion criteria and performed data extraction and quality analysis of the reviews. Eleven reviews with 65 primary studies were included. The syntheses were descriptive and by meta-analyses. Analysis of the risk of bias of systematic reviews was performed using the ROBIS instrument (Risk of Bias in Systematic Reviews); methodological quality was assessed using the AMSTAR 2 instrument (A MeaSurement Tool to Assess Systematic Reviews); and analysis of the strength of evidence followed the recommendations of the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). Fourteen studies of 1,350 participants provided evidence for meta-analysis. Despite the very low certainty of the evidence, findings suggest that the teaching strategies of problem-based learning and simulation enable the development of critical thinking in undergraduate nursing students. Risk of bias, high heterogeneity, limited number of studies, and reduced number of participants contributed to lower the level of certainty of the evidence. It is recommended that professors assess students' characteristics before choosing one or another teaching strategy and consider diversified use. The frequency and duration of the application of strategies is important, since the development of critical thinking occurs in a procedural and continuous way. It is recommended that researchers improve the report, including relevant information such as statistical data and characteristics of students and the teaching environment. The use of tools that guide a quality report is indicated. When planning clinical trials, it is important to predict and standardize the time of exposure to the teaching strategy and the number of sessions; use at least two clinical reasoning measurement scales and apply them at least before and after the intervention. These precautions bring robustness to the results. The social contribution of this unpublished thesis is the identification of effective teaching strategies for the development of critical thinking in nursing students, problem-based learning and simulation, thereby making it possible to improve the qualification of future nurses for a safe and evidence-based professional practice.

Política interministerial para la investigación, transferencia y fortalecimiento de la salud en territorio, una experiencia federal / Interministerial Policy for Research, Transfer and Strengthening of Health in the Territory, a Federal Experience

RESUMEN INTRODUCCIÓN: En marzo de 2023, en el marco del "Convenio Marco de Cooperación y Asistencia Técnica Mutua - MSAL/MINCYT", se creó el "Proyecto Federal Interministerial de Investigación, Transferencia y Fortalecimiento para la Salud en Territorio". El objetivo fue presentar un proceso de trabajo innovador entre dos ministerios, que sienta las bases para configurar un modelo de gestión de las políticas de investigación en salud con asiento federal y tendiente a potenciar las funciones y capacidades institucionales de cada sector. MÉTODOS: La coordinación del Proyecto se encuentra a cargo de un Comité Interministerial. En 2023 se realizó la Convocatoria para la presentación de un proyecto anual, que consta de dos componentes: A) Línea de investigación y transferencia; y B) Plan de fortalecimiento de las capacidades institucionales de las áreas de investigación de los ministerios de salud jurisdiccionales agrupadas en la Red Ministerial de Áreas de Investigación en Salud de Argentina. RESULTADOS: Las 24 jurisdicciones presentaron sus proyectos, y todos ellos resultaron aprobados. La estrategia tuvo un impacto en el fortalecimiento de los mecanismos de trabajo conjunto de dos ministerios nacionales, que debieron armonizar modalidades de gestión entre las áreas de investigación en salud y las representaciones de CyT en el ámbito jurisdiccional y entre los decisores en materia sanitaria y los actores del sistema científico. DISCUSIÓN: Esta experiencia contribuye a fortalecer las capacidades estatales, a la vez que permite identificar aspectos que requieren continuar siendo trabajados para consolidar nuevas modalidades de gestión interministeriales.

ABSTRACT INTRODUCTION: In March 2023, within the framework of the "Framework Agreement for Cooperation and Mutual Technical Assistance - MSAL/MINCYT", the "Federal Interministerial Project of Research, Transfer and Strengthening for Health in the Territory" was created. The objective was to present an innovative work process between the Ministry of Health (MSAL) and the Ministry of Science, Technology and Innovation (MINCYT), that lays the foundations for a management model of health research policies with a federal approach and aimed at enhancing the institutional functions and capacities of each sector. METHODS: The Project was coordinated by an Interministerial Committee. In 2023 there was a Call for the presentation of an annual project that consists of two components: A) Line of research and transfer; and B) Plan to strengthen the institutional capacities of the research areas of the jurisdictional health ministries grouped in REMINSA. RESULTS: The 24 jurisdictions presented their projects, and all of them were approved. The strategy strengthened the joint work mechanisms of two national ministries, that had to harmonize management patterns between health research areas and S&T representations at the jurisdictional level and between health decision-makers and the actors of the scientific system. DISCUSSION: This experience contributes to strengthening state capacities, while allowing to identify aspects that require continued work to reinforce new interministerial management patterns.

Concordance between referral and final diagnoses of pediatric patients with vascular malformations / Concordancia entre el diagnostico de referencia y final de pacientes pediátricos con malformaciones vasculares

Abstract Background: Vascular malformations (VaM) are a heterogeneous group of disorders resulting from the dysmorphogenesis of blood vessels. Although correct classification is relevant to providing adequate treatment according to evidence-based medicine, diagnostic terminology may be misused or need clarification. Methods: We conducted a retrospective study to measure agreement and concordance between referral and final confirmed diagnoses of 435 pediatric patients with VaM newly referred to the multidisciplinary Vascular Anomalies Clinic (VAC) using Fleiss kappa (κ) concordance analysis. Results: We found fair concordance between referral and confirmed diagnoses of VaM (κ 0.306, p < 0.001). Lymphatic malformations (LM) and VaM associated with other anomalies showed moderate diagnostic concordance (κ 0.593, p < 0.001 and κ 0.469, p < 0.001, respectively). Conclusions: Continuing medical education strategies are required to improve physician knowledge and diagnostic accuracy in patients with VaM.

Resumen Introducción: Las malformaciones vasculares (MVa) son un grupo heterogéneo de trastornos resultantes de la dismorfogénesis de los vasos sanguíneos. A pesar de que la correcta clasificación es relevante para brindar un adecuado tratamiento de acuerdo con la medicina basada en la evidencia, la terminología diagnóstica podría resultar confusa o utilizarse de manera inapropiada. Métodos: En este estudio retrospectivo se midieron el acuerdo y la concordancia entre los diagnósticos de referencia (o derivación) y los diagnósticos finales confirmados de 435 pacientes pediátricos con MVa recién remitidos a la Clínica de anomalías vasculares (CAV) multidisciplinaria, mediante el análisis de concordancia kappa de Fleiss (κ). Resultados: Se encontró una buena concordancia entre los diagnósticos de referencia (o derivación) y los diagnósticos confirmados de MVa (κ 0.306, p < 0.001). Las malformaciones linfáticas (LM) y las MVa asociadas con otras anomalías presentaron concordancias diagnósticas moderadas (κ 0.593, p < 0.001 y κ 0.469, p < 0.001, respectivamente). Conclusiones: Se requiere de estrategias de educación médica continua para mejorar el conocimiento de los médicos y la precisión diagnóstica de los pacientes con MVa.

Time Perspective and Decision-Making: A Study on Decisional Patterns in Argentinian Adults / Perspectiva temporal y toma de decisión: un estudio sobre patrones decisionales en adultos argentinos / Perspectiva temporal e tomada de decisão: um estudo sobre padrões decisórios em adultos argentinos

The first aim of this study was to adapt the mdmq to Argentinian Spanish and to collect evidence of its va-lidity and reliability; the second was to determine if time perspectives were adequate predictors of decision-making styles. A first sample of 536 participants served in the validation process; a second sample of 209 individuals who completed the mdmq and the Brief Zimbardo Time Perspective Inventory (ztpi) was used to conduct descriptive-correlational and regression analyses. Confirmatory factor analysis corroborated a fourfactor model with adequate internal consistency for each subscale. Regression analyses showed that future time perspective positively predicted the display of higher vigilant coping patterns ­adaptive and ratio-nal decision-making style­. Meanwhile, less future- time-oriented people were more likely to engage in defensive avoidance mechanisms to reach a decision. Past-negative and present-fatalistic time perspectives were positive predictors of non-vigilant decision-making style. It indicates that individuals with an aversive vision over their past experiences and present situation are more likely to engage in emotionally based and avoidant decision-making patterns. These findings support the reliability and construct-related validity of the mdmq for assessing decision-making styles among Argentinian individuals and set a step for con-ducting more in-depth research in the field of decision-making and time perspective.

Una primera muestra de 536 participantes sirvió para el proceso de validación y una segunda muestra de 209 individuos completó el mdmq y el Brief Zimbardo Time Perspective Inventory (ztpi), para un análisis descriptivo-correlacional y de regresión. El análisis factorial confirmatorio corroboró un modelo de cuatro factores con adecuada consistencia interna para cada subescala. Los análisis de regresión mostraron que la perspectiva del tiempo futuro predijo positivamente la aparición de patrones de afrontamiento más vigilantes ­estilo de toma de decisiones adaptativo y racional­, mientras que las personas que estaban menos orientadas al tiempo futuro tenían más probabilidades de involucrarse en mecanismos de evitación defensiva para tomar una decisión. Las perspectivas temporales negativas del pasado y fatalistas del presente fueron predictores positivos del estilo de toma de decisiones no vigilante, lo que indicaría que las personas con una visión aversiva sobre sus experiencias pasadas y la situación presente, son más propensas a involucrarse en tipos de toma de decisiones basadas en emociones y evasivas. Estos hallazgos respaldan la confiabilidad y la validez relacionada con el constructo del mdmq para evaluar los estilos de toma de decisiones entre los argentinos y marcan un paso para realizar investigaciones más profundas en el campo de la toma de decisiones y la perspectiva temporal.

Uma primeira amostra de 536 participantes foi usada para o processo de va-lidação e uma segunda amostra de 209 indivíduos completarou o mdmq e o Brief Zimbardo Time Perspec-tive Inventory (ztpi) e foi usada para realizar análises descritivas-correlacionais e de regressão. A análise fatorial confirmatória corroborou um modelo de quatro fatores com consistência interna adequada para cada subescala. As análises de regressão mostraram que a perspectiva do tempo futuro previu positivamente o surgimento de padrões de enfrentamento mais vigilantes ­estilos de tomada de decisão racionais e adaptativos­ enquanto as pessoas menos orientadas para o futuro eram mais propensas a se envolver em mecanismos de enfrentamento de evasão defensiva para tomar uma decisão. Perspectivas temporais negativas do passado e fatalistas do presente foram preditores positivos do estilo de tomada de decisão não vigilante, indicando que pessoas com uma visão aversiva de suas experiências passadas e da situação presente são mais propensas a se envolver em tipos de tomada de decisão baseadas em emoções e padrões evasivos. Essas descobertas apoiam a confiabilidade e a validade relacionada ao construto do mdmq para avaliar os estilos de tomada de decisão entre os argentinos e marcam um importante passo para realizar pesquisas mais profundas no campo da tomada de decisão e perspectiva de tempo.

Quais aspectos influenciam a priorização da Atenção Primária à Saúde pelos gestores municipais do Rio Grande do Sul - Brasil? / What aspects influence the prioritization of Primary Health Care by municipal managers in Rio Grande do Sul - Brazil?

Resumo A Atenção Primária à Saúde (APS) é o capaz de atingir ampla cobertura e resolutividade. Esta pesquisa avaliou os fatores associados a priorização que os gestores municipais da saúde do estado do Rio Grande do Sul (RS) dada à APS. Realizou-se estudo analítico seccional entre agosto de 2017 a maio de 2019 através da aplicação de um questionário via FormSUS aos 497 secretários municipais de saúde do RS, composto por 44 perguntas divididas em 4 blocos. Efetuou-se regressão logística múltipla para analisar fatores relacionados a formação com a priorização da APS. De 404 participantes, 66.8% relataram um grau máximo de priorização. Gestores com pós-graduação apresentaram maior a priorização do que aqueles com ensino fundamental (78,5% vs 58,8%, p<0.01). Em relação à área de pós-graduação, gestores com formação em saúde coletiva priorizaram mais a APS do que em outras áreas, ou nenhuma pós-graduação, respectivamente com 84%, 77,1% e 61,8% (p<0.01). Após ajuste por covariadas, ter pós-graduação em saúde coletiva ou em outra área permaneceram associadas a maiores chances de priorização. Os resultados podem fomentar iniciativas que considerem o nível e a área de escolaridade para esse cargo, com enfoque no critério técnico e não estritamente político.

Abstract Primary Health Care (PHC) is capable of achieving broad coverage and effectiveness. This study evaluated the factors associated with the prioritization that municipal health managers in the state of Rio Grande do Sul (RS) give to PHC. A cross-sectional analytical study was carried out between August 2017 and May 2019 using an online FormSUS questionnaire, consisting of 44 questions divided into 4 blocks, sent to 497 municipal health managers. Multiple logistic regression was performed to analyze factors associated with PHC prioritization. Out of 404 participants, 66.8% reported a maximum degree of prioritization. Managers with a postgraduate degree showed greater prioritization than those with elementary education (78.5% vs 58.8%, p<0.01). Regarding the postgraduate area, managers with training in public health prioritized PHC more than in other areas, or with no postgraduate studies, respectively with 84%, 77.1% and 61.8% (p<0.01). After adjusting for covariates, having a postgraduate degree in public health or in another area remained associated with greater chances of prioritization. The results may encourage initiatives that consider the level and area of education for this position focusing on technical, and not strictly political criteria.

Advances in clinical assessment and decision-making of intraductal papillary mucinous neoplasm in pancreas / 中华肝胆外科杂志

Intraductal papillary mucinous neoplasm (IPMN) is one of the precancerous lesions of the pancreas. Currently there is controversial over the management and follow-up strategy of IPMN, including the timing of surgery. The core problem lies in the accurate preoperative assessment of the nature of the lesions and the risk of malignant transformation. Cumulation of high-quality evidence and development of efficient evaluation methods are vital for the establishment of standardized decision-making system and the improvement of clinical benefits to patients. This review aims to summarize the consensus and controversies on surgical evaluation standards in the latest guidelines and representative literatures, and to look forward to the development direction of IPMN diagnosis and treatment decisions in combination with the progress of related evaluation techniques.

Contrasting effects of DOM and lisuride on impul-sive decision-making in delay discounting task / 中国药理学与毒理学杂志

OBJECTIVE The 5-HT2A receptor is the major target of classic hallucinogens.Both DOM(2,5-dimethoxy-4-methylamphetamine)and lisuride act at 5-HT2A receptors,and lisuride shares comparable affinity with DOM and acts as a partial agonist at 5-HT2A recep-tors.However,not like DOM,lisuride lacks hallucinogenic properties.Impulsive decision-making refers to the prefer-ence for an immediate small reinforcer(SR)over a delayed large reinforcer(LR).The current study aims to compare the effects of DOM and lisuride on impulsive decision-making and further to investigate the possible receptor mechanisms responsible for the actions of the two drugs.METHODS Impulsive decision-making was evaluated in male Sprague-Dawley rats by the percent-age of choice for the LR in delay discounting task(DDT).Delay to the LR changed in an ascending order(0,4,8,16,and 32 s)across one session.RESULTS DOM(0.3 and 0.5 mg·kg-1)increased impulsive decision-making,and the effects of DOM(0.5 mg·kg-1)was blocked by the 5-HT2A receptor antagonist ketanserin(1.0 mg·kg-1)rather than the 5-HT2C receptor antagonist SB-242084(1.0 mg·kg-1).Contrarily,lisuride(0.1,0.3 and 0.5 mg·kg-1)decreased impulsive decision-making.The effects of lisu-ride(0.3 mg·kg-1)were not antagonized by ketanserin(1.0 mg·kg-1),selective 5-HT1A antagonist WAY-100635(1.0 mg·kg-1)or selective dopamine D4 receptor antagonist L-745870(1.0 mg·kg-1),but were attenuated by the selec-tive dopamine D2/D3 receptor antagonist tiapride(40 mg·kg-1).CONCLUSION DOM and lisuride have contrasting effects on impulsive decision-making via distinct recep-tors.DOM-induced increase of impulsivity is mediated by the 5-HT2A receptor,while lisuride-induced inhibition of impulsivity is regulated by the dopamine D2/D3 receptor.
