Este artículo constituye una reflexión acerca del asunto del tiempo en el espacio digital, entendido este como el conjunto espacial virtual por medio del cual interactuamos online. Por medio de una breve síntesis de las diferentes elaboraciones del concepto del tiempo y su transición en las diversas culturas y especies, se describe en primer lugar, el espacio digital como otro espacio que, para ser comprendido, se puede relacionar con la experiencia estética. En este espacio, el ser humano se ha desvinculado del espacio físico real en el que habita, por medio de algoritmos en evolución, desmaterializando el cuerpo físico, los lugares y los objetos para habitar en un lugar que muta y que tiene características propias que no es el espejo del espacio físico real, sino más bien un lugar con cualidades particulares, con medidas, peso y formas de habitar, que abren la posibilidad de replantear también la métrica del tiempo que allí transcurre, intransferible al mundo físico.El objetivo de esta investigación es converger en una instalación de carácter artístico en el Museo de Arte Contemporáneo de Santiago de Chile, en abril de 2023, la cual tiene contemplado la construcción de un reloj de dimensiones 300 x 150 x 25 centímetros, cuyas manecillas se movilizarán dando horarios diversos que no corresponden al tiempo del mundo real, sino horarios variables que responderán a tiempos diversos según inputs de variadas índoles.

La leptospirosis es una enfermedad zoonótica causada por las espiroquetas patógenas Leptospira. La enfermedad tiene impacto significativo en varias regiones del mundo, la OMS la cataloga como enfermedad emergente de salud pública, por el potencial epidémico que puede tener, principalmente relacionado con condiciones hidrometeorológicas. Los síntomas incluyen fiebre repentina, fuertes dolores de cabeza, dolor muscular, náuseas y escalofríos. La leptospirosis, también se considera una enfermedad desatendida que se asocia a poblaciones que viven en condiciones de vulnerabilidad en entornos urbanos y rurales. Muchos casos de leptospirosis están relacionados con ocupaciones específicas, como la agricultura y el manejo de animales. El impacto en la salud animal se refleja en las pérdidas económicas y las situaciones de riesgo entrelazan la triada humano-animal-ecosistema. La leptospirosis ha estado presente desde tiempos remotos y aún  en la actualidad se observa que su prevalencia permanece constante. La falta de sospecha clínica entre los médicos, sus síntomas inespecíficos y la disponibilidad limitada de pruebas de diagnóstico, la hacen una enfermedad relativamente desconocida. El artículo describe el panorama histórico epidemiológico de la leptospirosis en Yucatán. Se realizó una revisión sistemática de la literatura en las bases de datos PubMed, Scielo, Latindex, Google Scholar.

Diabesity is a neologism that we use to describe Type 2 diabetes mellitus in the context of obesity. In this descriptive review, we aim to analyze the phenomenon of diabesity in the context of the Yucatecan Maya population, given the demographic importance of this ethnic group in Mexico and due to the high prevalence of diabetes and obesity observed in this group. Firstly, we describe the phenotypic and genotypic traits associated with diabesity. We also discuss the role of the sociocultural factors that have impacted the dietary pattern of the Maya, the available evidence regarding the phenotypic characteristics acquired during the early stages of development, their possible repercussions on the metabolism and the presence of obesity and diabetes. Finally, we propose that the failure of insulin secretion and glucolipotoxicity are common factors and a possible unifying factor of diabesity within the Maya population. For this purpose, we draw upon primary sources of information, including original research articles, chapters from edited books about diabesity and sociohistorical essays on the Maya population.

Antipsychotics are the first line of treatment for psychotic symptoms and syndromes. Psychosis can present itself as: delusions, hallucinations, disorganized thinking, and altered behavior. It is estimated that 13 to 23% of the population will experience these symptoms at some point in their lifetime. This clinical review aims to assist in the decision-making about when and how to introduce antipsychotics into primary health care, considering their effectiveness, side effect profile, and the main care practices for relevant comorbidities. A literature review was carried out in the electronic databases PubMed, BMJ Best Practice, and UpToDate — electronic databases summarizing evidence — from October to November 2020. Articles that addressed the introduction of antipsychotics into primary health care, in patients over 18 years of age, published after 2010, in Portuguese, English, Spanish or French, were included. A total of 76 articles were considered eligible. Of these, 27 were selected for full reading. The antipsychotic should be recommended for anyone who experiences a first episode of psychosis. Preferably, the therapeutic choice should be part of a person-centered shared decision-making, considering the side effects. There is no superiority in effectiveness between one antipsychotic or another, not even between groups. The profile of efficacy, adverse effects, safety, and tolerability of the main drugs available were analyzed, facilitating decision-making regarding the introduction of antipsychotics. Due to the scarce national literature, it was not possible to analyze the specific profile for the Brazilian population.

Introduction: After the institution of National Curriculum Guidelines for Medicine undergraduate courses, it is expected that the extended clinical practice will predominate in medical training, that is, one that has as its central focus individuals and their particularities. Objective: Through this study, we sought to comprehend the conceptions about clinical practice in the minds of students and professor of an undergraduate course in Medicine at a federal university located in the south of the country. Methods: This is an exploratory and qualitative study approved by the Research Ethics Committee of a federal university, under the opinion No. 2.950.932, of October 9th, 2018. Data collection was based on interviews with medical professors (n=21) and academics focal groups (n=43) that, subsequently, were processed by Bardin’s content analysis. Results: Aspects inherent to the extended clinical practice were brought up, mainly those regarding a good doctor-patient relationship, the need to develop communication skills, and the balance between the humanistic, ethical and technical components. However, some statements aligned to the traditional clinical practice have been noticed, mostly related to the practice focused on diagnosis and treatment. Conclusions: Through these results, it is possible to conclude that, despite the presence of the extended clinical practice in the medical degree, it has not yet been fully implemented.
