¿Es posible desarrollar investigaciones clínicas utilizando sustancias psicodélicas en Uruguay?: pasado y presente de las investigaciones sobre el potencial medicinal de los psicodélicos / Is it possible to develop clinical research using psychedelic substances in Uruguay ?: past and present of research on the medicinal potential of psychedelics

Los psicodélicos son sustancias capaces de alterar la conciencia, a través de su efecto sobre la transmisión serotoninérgica en el sistema nervioso central. En sus formas de ingesta tradicional son utilizados en rituales, con fines espirituales y medicinales. En el campo científico, dichas sustancias fueron estudiadas para posibles aplicaciones psicoterapéuticas en el período 1950-1970, y luego fueron excluidas de la investigación clínica durante las posteriores décadas. Sin embargo, desde 1990 asistimos a un «renacimiento de los estudios sobre psicodélicos¼, donde estas sustancias están siendo estudiadas en su potencial clínico para el tratamiento de distintos trastornos menta-les. El presente artículo describe y reflexiona sobre la historia de estas investigaciones en Uruguay y en el mundo, tanto en su primera etapa (1950-1970) como en su renacimiento posterior (1990-actualidad), dejando planteado un escenario en el que sea posible avanzar en el campo de las investigaciones clínicas con psicodélicos en nuestro país.

Psychedelics are substances capable of altering consciousness, through their effect on serotonergic transmission within the central nervous system. In their traditional uses, psychedelics are consumed during rituals, for spiritual and medicinal purposes. In the scientific field, these substances were studied because of their possible psychotherapeutic applications in the period 1950-1970. Afterwards, psychedelics were banned from clinical research for decades. Nevertheless, since 1990 we are witnessing a "renaissance of psychedelic studies", where these substances are being studied because of their clinical potential applications for the treatment of different mental disorders. The current article describes and analyzes the history of these research in Uruguay and in the world, both in its first stage (1950-1970) and in the present "renaissance" (1990-present). The article suggests a future scenario, where Uruguay could play a major role in the field of psychedelic research.

Research progression in clinical treatment of gastric cancer in 2020 / 中华胃肠外科杂志

Gastric cancer is a common type of malignant tumors, but its clinical prognosis remains unsatisfactory. Up to 2020, a growing number of high-quality clinical researches has provided reliable evidence for clinical practice. Evidences from surgery, perioperative treatment and immunotherapy, such as changes in surgical methods, improvement of perioperative chemotherapy and combination of immune and chemotherapy strategy, provided the possibility to improve the clinical efficacy of gastric cancer. In our clinical practice, gastrointestinal surgeons need to integrate the current research progression and develop individualized strategy for different patients, which is expected to further improve the prognosis and quality of life for patients with gastric cancer.

Research Progress of Immune Checkpoint Inhibitor-associated Myocarditis / 中国肺癌杂志

Immune checkpoint inhibitors (ICIs) is a negative regulatory factor antibody, which activates T cells to play an anti-tumor effect in immunotherapy, and can also cause immune-related adverse responses, thereby inducing a series of immune related adverse events (irAEs). Among these irAEs, although the incidence of ICIs-related myocarditis is very low, the fatality rate is significantly higher than other adverse reactions, close to 50%. Clinicians should be vigilant when applying ICIs, but the pathogenesis of ICIs-related myocarditis is still unclear. This article combines the recent research results of ICIs to summarize the mechanism and clinical manifestations of ICIs-related myocarditis, so as to improve clinicians' understanding of the adverse reactions.

Treatment and research lines for the patient with COVID-19. What do we have and where are we going?

ABSTRACT Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents the most significant global public health crisis of this generation. From the beginning of the pandemic, several publications and on-line resources about different treatment lines have been done, and development effort in response to the COVID-19 pandemic to investigate potential therapies is unprecedented. Unfortunately, until now, there is not enough evidence to recommend any specific anti-COVID19 treatment. Randomized clinical trials and high-quality evidence, even in the middle of a pandemic, are needed. We provide a review of the latest published literature on the therapeutic strategies and current investigational lines for SARS-CoV-2.

Two years into the Brazilian Reproducibility Initiative: reflections on conducting a large-scale replication of Brazilian biomedical science

Scientists have increasingly recognised that low methodological and analytical rigour combined with publish-or-perish incentives can make the published scientific literature unreliable. As a response to this, large-scale systematic replications of the literature have emerged as a way to assess the problem empirically. The Brazilian Reproducibility Initiative is one such effort, aimed at estimating the reproducibility of Brazilian biomedical research. Its goal is to perform multicentre replications of a quasi-random sample of at least 60 experiments from Brazilian articles published over a 20-year period, using a set of common laboratory methods. In this article, we describe the challenges of managing a multicentre project with collaborating teams across the country, as well as its successes and failures over the first two years. We end with a brief discussion of the Initiative's current status and its possible future contributions after the project is concluded in 2021.

Diabetes research in Mexico: a map of 13 years of public funding / La investigación en diabetes en México: un mapa de 13 años de financiamiento público / Pesquisa em diabetes no México: um mapa de 13 anos de financiamento público

Abstract: In Mexico, diabetes represents a serious public health problem and a high-cost disease for the health system. Health research is essential for generating new knowledge to combat such a serious issue, however, there is not enough information on how to generate and use it. This paper examines the public funding of 303 diabetes research projects, granted by the National Council of Science and Technology in Mexico between 2002 and 2014. The projects were systematized and classified according to their type of research, discipline or subject, and aim of knowledge. Considering these information, an econometric model that links the funding with the characteristics of the projects was prepared. The results show that the funding is focused on the basic and biomedical areas, particularly on genetic research, and also that diabetes research resources have increased over time, not steadily, but rather cyclically. In diabetes research projects there is a high level of concentration at several dimensions: research areas, topics, objects, institutions conducting research, and regions. The analysis of the resource allocation suggests that Mexico needs a stronger and oriented diabetes research agenda, including in its bases discussions about balance between basic and applied research, and about oriented research towards practical implementations. The importance of promoting health systems research to improve diabetes care is also discussed, as well as implementing mechanisms to assess the impact of diabetes research in short, medium and long term, as part of Mexico's science and technology policy.

Resumen: En México la diabetes es un grave problema de salud pública y es una enfermedad de alto costo para el sistema de salud. La investigación en salud es esencial para generar nuevo conocimiento para combatir este problema, pero existe escasa información sobre su generación y uso. Este trabajo examina el financiamiento público de 303 proyectos de investigación sobre diabetes, otorgados por el Consejo Nacional de Ciencia y Tecnología en México, entre 2002 y 2014. Los proyectos fueron sistematizados y clasificados de acuerdo con el tipo de investigación, disciplina o temática, y objetivo de generación de conocimiento. Con estos datos, se elaboró un modelo econométrico que relacional el financiamiento con las características de los proyectos. Los resultados muestran que el financiamiento está centrado en áreas básica y biomédica, particularmente en investigación genética, y que los recursos destinados a la investigación en diabetes se han incrementado en el tiempo pero no de manera constante, sino coyuntural. En los proyectos de investigación sobre diabetes hay un alto nivel de concentración en varias dimensiones: áreas de investigación, temáticas, objeto de estudio, instituciones que realizan la investigación, y regiones. El análisis de la asignación de recursos sugiere que México necesita una agenda de investigación en diabetes más fuerte y orientada, con fundamento en discusiones sobre el equilibrio entre investigación básica y aplicada, y sobre investigación orientada hacia implementaciones de tipo práctico. SE discute también la importancia de promover investigación sobre el sistema de salud para mejorar el cuidado a los pacientes con diabetes, así como la de implementar mecanismos para evaluar el impacto de la investigación en diabetes a corto, mediano y largo plazo, como parte de la política de ciencia y tecnología en México.

Resumo: No México, o diabetes representa um grave problema de saúde pública e uma doença de custo elevado para o sistema de saúde. A pesquisa em saúde é essencial para gerar novos conhecimentos para combater o problema, mas não há informação suficiente para gerar e utilizá-los. O artigo examina o financiamento público de 303 projetos de pesquisa em diabetes, através do Conselho Nacional de Ciência e Tecnologia do México entre 2002 e 2014. Os projetos foram sistematizados e classificados de acordo com o tipo de pesquisa, disciplina ou assunto e o objetivo do conhecimento. Com base nessa informação, foi preparado um modelo econométrico que associa o financiamento às características dos projetos. Os resultados mostram que o financiamento está concentrado nas áreas de pesquisa básica e biomédica, principalmente em pesquisa genética, e que os recursos para pesquisa em diabetes aumentaram ao longo do tempo, não continuamente, mas ciclicamente. Os projetos de pesquisa em diabetes mostram uma forte concentração em diversas dimensões: área de pesquisa, tema, objeto, instituição que realiza a pesquisa e região do país. A análise da alocação de recursos sugere que o México precisa de uma agenda de pesquisa mais forte e orientada, com bases que incluam discussões sobre o equilíbrio entre pesquisa básica e aplicada, e para pesquisa voltada para implementações práticas. O artigo também discute a importância de promover pesquisas em sistemas de saúde para melhorar os cuidados em diabetes, além de implementar mecanismos para avaliar o impacto da pesquisa em diabetes no curto, médio e longo prazo como parte da política de ciência e tecnologia do país.

¿Es tiempo de modificar la vinculación pregrado postgrado en la educación médica chilena? Reflexiones sobre una vía de doble titulación Médico cirujano/Doctor en ciencias médicas / Time to change the graduate-postgraduate liaison in Chilean medical education? Reflections about a double certification as Physician and Doctor in medical sciences

In the last 150 years, scientific research has produced extraordinary discoveries in Medicine and there is no doubt that research will continue contributing substantially in the future but there is no the same conviction regarding how to provision such capacities in medical graduates. In Chile, the Faculties of Medicine created several doctorate programs in Medical Sciences (Ph.D.) to strengthen medical research. However, the low number of physicians who apply to these programs is a caveat. These programs provide the advanced third-cycle competencies expected by students aspiring for an excellence research certification and their incorporation into academia. Universities stand out in their capacity to adapt themselves to educational needs, developing programs designed to fill specific gaps. Ph.D. programs intercalated to the medical career show that this is the correct approach. The development of specific doctorate programs for the small number of physicians interested in research and for medical students with a strong interest in research could be an innovative solution to motivate and encourage them to develop a career in clinical investigation. Using this approach, Medical Schools and Doctorate in Medical Sciences programs would jointly stimulate the training of medical scientists.
