Introduction Hospital delirium is a frequent, serious, costly, and underrecognized acute disorder of attention and cognition. Therefore, the prevention of hospital delirium is not only desirable for patients, caregivers, healthcare professionals, and the health system itself, but also a moral duty. Objective To identify and synthetize the main ethical aspects that arise related to the prevention of hospital delirium in patients 65 years and older. Methods A scoping review was carried out in Embase, Medline, and Web of Science. Articles published (...) in English or Spanish analyzing any pharmacologic, non-pharmacologic, or multicomponent intervention for prevention of delirium in hospitalized patients aged 65 years and over were included. Results Twenty-seven studies were included. Based on the frequency of appearance and the relevance, our findings were organized into three main areas. The first one was related to the principle of nonmaleficence and collected findings about the iatrogenic causes of hospital delirium and the use of restraints systems. The second area analyzed the impact of delirium in patients, families, and healthcare professionals from a relational ethics perspective, and addressed the family presence as a factor to prevent delirium. Finally, the third area is related to the quality of care. Conclusion Prevention of delirium in hospitals is essential to avoid the discomfort and potential clinical complications of patients, as well as the suffering of their relatives, caregivers, and healthcare professionals. Policymakers and healthcare managers are encouraged to make the required efforts to prevent delirium in hospitalized older patients. (shrink)

Este artículo retoma los criterios convergentes que debaten la configuración epistemológica de la posmodernidad en América Latina. Para ello, me valgo principalmente de los postulados de George Yúdice, Raúl Bueno y Beatriz Sarlo, quienes coinciden en formular y demostrar que todo intento de sincretizar lo que se está desarrollando en este movimiento es inadecuado. Por esa razón, será de importancia considerar este paradigma desde la filología, la etnografía, lo social y lo cultural, ya que muchos de sus componentes tendrán (...) un soporte capitalista, el cual será revelado con pormenores en el decurso de este trabajo.

Este artículo fundamenta la condición histórica de la posmodernidad, con la intención de dilucidar los enclaves dicotómicos, heterogéneos, irracionales y relativistas que la conforman. Esta se caracteriza por la propalación de paradigmas ambivalentes y polémicos en función de epistemologías estáticas provenientes de las culturas tradicionales y ortodoxas. Por ende, el objetivo es contrastar la configuración de esta etapa al incluir lo intercultural como proyecto social, que postula Beatriz Sarlo, que tiene como propósito enriquecer y resguardar las manifestaciones artísticas, lingüísticas (...) y culturales a nivel global; es decir, se asume lo que Fredric Jameson considera como una totalidad orgánica.

Este artículo fundamenta los factores que impiden que en Latinoamérica no sea notorio un desarrollo asequible de la creación de formulaciones teóricas. Uno de los grandes problemas se corrobora al detectar que sus postulados no son tan auténticos como sí los son en otros continentes. Y eso será debido a su estado de subordinación con respecto a estos países. Esa realidad los pone en una condición periférica, propia del “sur global”. Y lo que se busca es fluctuar propuestas antisistemas, socialistas (...) y localistas. Para demostrar esa realidad desde los ámbitos sociales y literarios, se realizó un análisis cultural con el soporte de textos interdisciplinarios, que dan constancia de la oscilación de la historia latinoamericana y sus fenómenos culturales. Los autores utilizados fueron Antonio Cornejo Polar (1981; 1982; 1989), Roberto Fernández Retamar (2005), Néstor García Canclini (1995; 2004), Ángel Rama (1984), Beatriz Sarlo (1996), entre otros.

Octavio Paz representa las fiestas mexicanas en El laberinto de la soledad (1950) con un rasgo adverso y relativista, que se opone a la unificación de la cultura como un instintivo. Inmediatamente, este carácter es reconocible desde la lógica posmoderna, la misma que trabaja Beatriz Sarlo. Al ser así, la configuración que se le atribuye a estas celebraciones cuenta con el propósito de hallar notoriamente la interrelación pluricultural y su respectiva difusión. Esa es la orientación que se le brinda (...) al tópico de la relatividad, que se respalda también de las concepciones de la semiótica tensiva de Jacques Fontanille (la inclusión del cuadrado semiótico) y la configuración teórica del tiempo, tal como la fundamenta Paul Ricoeur. De estas, se aprecia el funcionamiento de la dinámica de opuestos, inmersa en el desarrollo de las festividades. Asumiendo que este estudio abarca a un autor distinguible, he reconsiderado previamente un panorama hermenéutico a esta investigación (análisis bibliográficos en torno a la obra). (shrink)

Background: Despite the reported harms and ethical concerns about physical restraint use in the critical care settings, nurses’ intention to apply them is unequal across countries. According to the theory of planned behaviour, eliciting nurses’ beliefs regarding the use of physical restraints would provide additional social information about nurses’ intention to perform this practice. Aim: To explore the salient behavioural, normative and control beliefs underlying the intention of critical care nurses to use physical restraints from the theory of planned behaviour. (...) Research design: A belief elicitation study was conducted. Participants and research context: Twenty-six critical care nurses were purposively sampled across gender, work-shift patterns and professional experience in five intensive care units of three hospitals in Spain. Data were obtained from a nine-item open-ended questionnaire and a focus group. Deductive content analysis was performed. Ethical considerations: Ethical approval was obtained from the hospital ethics committee. Participants were assured their participation was voluntary. Findings: Nurses framed the use of restraints as a way of prioritising patients’ physical safety. They referred to contextual factors as the main reasons to justify their application. Nurses perceived that their decision is approved by other colleagues and the patients’ relatives. Some nurses started advocating against their use, but felt powerless to change this unsafe practice within an unfavourable climate. Control beliefs were linked to patients’ medical condition, availability of alternative solutions, analgo-sedation policies and work organisation. Discussion: Safety arguments based on the surrounding work environment were discussed. Conclusion: Nurses’ behavioural and control beliefs were related. Nurses should be trained in alternatives to physical restraint use. The impact of analgo-sedation protocols, relatives’ involvement, leadership support and intensive care unit restraint policies on physical restraint practices need to be revised. Further research is required to explore why nurses do not act with moral courage to change this harmful practice. (shrink)

Background: Nurses who practice limitation of therapeutic effort become fully involved in emotionally charged situations, which can affect them significantly on an emotional and professional level. Objectives: To describe the experience of intensive care nurses practicing limitation of therapeutic effort. Method: A qualitative, phenomenological study was performed within the intensive care units of the Madrid Hospitals Health Service. Purposeful and snowball sampling methods were used, and data collection methods included semi-structured and unstructured interviews, researcher field notes, and participants’ personal letters. (...) The Giorgi proposal for data analysis was used on the data. Ethical considerations: This study was approved by the Ethical Research Committee of the relevant hospital and by the Ethics Committee of the Rey Juan Carlos University and was guided by the ethical principles of voluntary enrollment, anonymity, privacy, and confidentiality. Results: In total, 22 nurses participated and 3 themes were identified regarding the nurses’ experiences when faced with limitation of therapeutic effort: (a) experiencing relief, (b) accepting the medical decision, and (c) implementing limitation of therapeutic effort. Conclusion: Nurses felt that, although they were burdened with the responsibility of implementing limitation of therapeutic effort, they were being left out of the final decision-making process regarding the same.

Background: The concept of professional commitment is being widely studied at present. However, although it is considered an indicator for the most human part of nursing care, there is no clear definition for it, and different descriptors are being used indiscriminately to reference it. Objective: The aim of this study is to clarify the concept of professional commitment in nursing through the Rodgers’ evolutionary concept analysis process. Design: Systematic search using English and Spanish descriptors and concept analysis. Studies published between (...) 2009 and June 2015, front-to-back analysis of the Nursing Ethics journal and manual check of articles cited in studies related to the Nijmegen Professionalism Scale. Research design: The procedure of concept analysis developed by Rodgers was used. Ethical considerations: Although the topic was not labeled as sensitive and subject to ethical approval, its realization was approved by the Ethical Committee of Clinical Research of Aragon (CEICA) approved the study on 18 March 2015 and also careful procedures have been followed according to ethics expressed in the Declaration of Helsinki. Findings and discussion: A total of 17 published studies. A clear definition of the concept was made, and surrogate terms, concept dimension, differential factors related to the concept, sociocultural variations and consequences for nursing practice were identified. Conclusion: There is a need for continuous advancement in the development of the concept, specific actions to encourage this and the improvement of evaluation methods for its study. (shrink)

Polo‐like kinase 1 (PLK1) is a serine/threonine kinase that plays multiple and essential roles during the cell division cycle. Its inhibition in cultured cells leads to severe mitotic aberrancies and cell death. Whereas previous reports suggested that Plk1 depletion in mice leads to a non‐mitotic arrest in early embryos, we show here that the bi‐allelic Plk1 depletion in mice certainly results in embryonic lethality due to extensive mitotic aberrations at the morula stage, including multi‐ and mono‐polar spindles, impaired chromosome segregation (...) and cytokinesis failure. In addition, the conditional depletion of Plk1 during mid‐gestation leads also to severe mitotic aberrancies. Our data also confirms that Plk1 is completely dispensable for mitotic entry in vivo. On the other hand, Plk1 haploinsufficient mice are viable, and Plk1‐heterozygous fibroblasts do not harbor any cell cycle alterations. Plk1 is overexpressed in many human tumors, suggesting a therapeutic benefit of inhibiting Plk1, and specific small‐molecule inhibitors for this kinase are now being evaluated in clinical trials. Therefore, the different Plk1 mouse models here presented are a valuable tool to reexamine the relevance of the mitotic kinase Plk1 during mammalian development and animal physiology. (shrink)

In this article, a mixed integer linear program model is proposed for the production, lot sizing, and scheduling of automotive plastic components to minimize the setup, inventory, stockout, and backorder costs, by taking into account injection molds as the main index to schedule on parallel flexible injection machines. The proposed MILP considers the minimum and maximum inventory capacities and penalizes stockout. A relevant characteristic of the modeled problem is the dependence between mold setups to produce plastic components. The lot sizing (...) and scheduling problem solution results in the assignment of molds to machines during a specific time period and in the calculation of the number of components to be produced, which is often called lot size, following a sequence-dependent setup time. Depending on the machine on which the mold is setup, the number of units to be produced will be distinct because machines differ from one another. The stock coverage, defined in demand days, is also included in the MILP to avoid backorders, which is highly penalized in the automotive supply chain. Added to this, the proposed model is extended by considering setup common operators to respond to and fulfill the constraints that appear in automotive plastic enterprises. In this regard, the MILP presented solves a lot-sizing and scheduling problem, emerged in a second-tier supplier of a real automotive supply chain. Finally, this article validates the MILP by performing experiments with different sized instances, including small, medium, and large. The large-sized dataset is characterized by replicating the amount of data used in the real enterprise, which is the object of this study. The goodness of the model is evaluated with the computational time and the deviation of the obtained results as regards to the optimal solution. (shrink)

Instalada na Universidade Federal do Rio Grande do Sul (UFRGS) logo após o golpe civil-militar 1964, a Comissão Especial de Investigação Sumária (Ceis) teve como objetivo investigar ações consideradas subversivas, envolvendo professores, funcionários e estudantes.

New technologies could facilitate new ways of cheating. This emerging scenario places academic integrity policy in higher education institutions as critical. Academic integrity scholars have designed conceptual frameworks to analyze academic integrity policy. The body of the literature on academic integrity policy analysis includes studies developed in North America, Europe, and Australia. However, insight into several regions of the world is lacking. This pioneering study in the Chilean context analyzes documents addressing academic integrity at forty-three accredited universities. Using a qualitative (...) research design, we framed this policy analysis in the five core elements of exemplary academic integrity policy: access, approach, responsibility, detail, and support. The findings revealed challenges with accessing documents online, a strong presence of legal language that might not be understandable to all students, and a scarcity of information about review cycles. The punitive approach was prevalent, with a significant focus on students’ conduct. Signs of collaboration and mechanisms for promoting academic integrity cultures were nearly absent. The documents primarily targeted students and the roles of other stakeholders concentrated on the enforcement of sanctions and misconduct investigations. The analysis also showed the use of general definitions to describe academic integrity breaches, inconsistency across the system in defining plagiarism and a lack of guidance to address contract cheating and unauthorized use of generative artificial intelligence. The findings also highlighted the unavailability of institutional support to teach, learn, and research with integrity or references to research-based practices. We propose twelve practical recommendations for policymakers and academic integrity advocates. (shrink)

El objetivo de este trabajo es analizar los ejemplos que se dan en las obras tradicionales del denominado καί estructural con el fin de determinar sus características desde una perspectiva más actual. Este es uno de los tipos de καί adverbial que se distinguen, pero, como veremos, se trata de una categoría compleja en la que, sobre la base de su aparición en una oración subordinada, se han mezclado al menos tres usos más o menos habituales de καί adverbial: aditivo, (...) identificativo y corresponsivo. The aim of this paper is to analyse the examples of the so-called structural καί from a modern perspective. The examples are taken from the traditional grammars, in which this adverbial use of καί is usually distinguished. As it will be shown, this is in fact a complex category, established on the basis of its appearance in a subordinate clause and including three quite common uses of adverbial καί: additive, identificational and corresponsive.

This interview with Antonio A. Arantes, Brazilian anthropology professor and recognized specialist on the topics of intellectual property and traditional knowledge, addresses the 2008 request by Brazilian ayahuasca groups to be recognized as part of the immaterial cultural heritage of Brazil. In the first portion of the interview, Arantes reflects on the challenges of the new conceptions of the Brazilian national immaterial policy program. He discusses several examples of cultural goods recognized by the Brazilian state, such as the candomblé and (...) the samba, and analyzes the controversial issues involving authenticity and tradition in these and other similar cases. In the second portion, Arantes reflects on the specific case of ayahuasca, the relationship of this cultural heritage request to legal issues, the challenges to define exactly what aspects should be recognized, and speculates on the chances that these religious groups will come to be recognized as a national symbol of Brazil.

Individuals attribute a higher truth value to repeated compared to novel information, the well-known truth effect. Also, information that contradicts what we have heard earlier is considered falser than both repeated and completely new information, known as the contradiction effect. These two effects are a challenge to the correction of misinformation because one cannot easily correct earlier misleading claims. In the present paper, we show a new and important factor that enhances the effectiveness of corrections, the syntactic placement of the (...) contradiction. We argue that because the subject of a sentence has a stronger psychological importance than the object, a contradiction of the subject (compared to the object) is felt as a stronger contrast to the earlier information and thus experienced as more false. Experiments 1 and 2 provided null results, possibly due to confounding material and task. Crucially, Experiments 3–5 (total N = 628) reliably showed that contradictions of the subject were perceived to be falser than contradictions of the object. (shrink)

El 75 aniversario del artículo seminal de Turing y el centenario de su nacimiento ocurren en 2011 y 2012, respectivamente. Es natural revisar y valorar las contribuciones que hizo Turing en campos muy diversos a la luz de los desarrollos que sus pensamientos han producido en muchas comunidades científicas. Aquí, la idea principal es discutir como el trabajo de Turing nos permite cambiar nuestra visión sobre los fundamentos de las Matemáticas, de forma similar a como la mecánica cuántica cambió nuestra (...) concepción de la Física. Nociones básicas como compatibilidad y universalidad se discuten en un contexto amplio, haciendo énfasis especial en como a la noción de complejidad se le puede dar un significado preciso después de Turing, es decir, no solo cualitativo sino cuantitativo. Al trabajo de Turing se le da una perspectiva histórica en relación a algunos de sus precursores, contemporáneos y matemáticos que tomaron y llevaron sus ideas aún más allá. (shrink)
