The consideration of racial differences in the biology of disease and treatment options is a hallmark of modern medicine. However, this time-honored medical tradition has no scientific basis, and the premise itself, that is, the existence of biological differences between the commonly known races, is false inasmuch as races are only sociocultural constructions. It is time to rid medical research of the highly damaging exercise of searching for supposed racial differences in the biological manifestations of disease. The practice not only (...) condoned but required by the National Institutes of Health of utilizing racial identification as a demographic characteristic with assumed biological implications is at best badly flawed, and at worst unintentionally contributes to perpetuating the fallacy of natural differences between persons of different skin color, which has been used in the past to advance the cause of racial discrimination.

The antioxidant role of carotenoids in the living organism was proposed as a possible basis for the honesty of carotenoid‐based signals. However, recent studies have questioned the relevance of carotenoids as powerful antioxidants in vivo. Current evidence does not seem to support the “antioxidant role” hypothesis, but it does not allow us to reject it either. This paper proposes some steps to solve this controversy, such as taking a dynamic approach to antioxidant responses, designing protocols that expose individuals to oxidative (...) challenges, analyzing tissues other than blood, and obtaining measures of antioxidant capacity and oxidative damage simultaneously. However, it should be considered that, irrespective of their antioxidant potential, carotenoids might still give information on oxidative stress levels if they are particularly sensitive to free radicals. Finally, lumping together the immunostimulatory and antioxidant roles of carotenoids should be avoided as these functions are not necessarily associated. (shrink)

Background: In the university context, assessing students’ attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. Research objective: To assess the effect of a blended-learning model, based on professional ethics and related to clinical practices, on physiotherapy students’ attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = (...) 64; experimental group, n = 65). Both groups followed clinical practices for 8 months. Control group performed a public exposition of a clinical case about professional ethics. By contrast, an 8-month blended-learning programme regarding professional ethics was worked out for experimental group. An online syllabus and online activities were elaborated, while face-to-face active participation techniques were performed to discuss ethical issues. Students’ attitudes, knowledge and opinions towards learning professional ethics were assessed. Ethical considerations: The study was approved by the University Ethic Committee of Human Research and followed the ethical principles according to the Declaration of Helsinki. Findings: After the programme, attitudes and knowledge towards learning professional ethics of experimental group students significantly improved, while no differences were observed in control group. Moreover, opinions reported an adequate extension of themes and temporization, importance of clinical practices and interest of topics. Case study method and role playing were considered as the most helpful techniques. Conclusion: The blended-learning programme proposed, based on professional ethics and related to clinical practices, improves physiotherapy students’ attitudes, knowledge and opinions towards learning professional ethics.

El propósito del presente artículo radica en examinar el cruce de influencias entre la teoría ontológica y la praxis política. Más específicamente, nos interesa analizar de qué manera el estatus otorgado al khorismós platónico, es decir, al límite irrebesable entre el ámbito de los archaí y la dimensión de lo fenoménico, ha determinado el quehacer político europeo. La tesis que nos proponemos defender se formularía, pues, de la siguiente forma: las distintas posturas políticas que han caracterizado de manera paradigmática nuestro (...) devenir cultural son un correlato del modo en el que ha sido pensada la diferencia ontológica que supone el khorismós platónico.

Introducción: Los cambios biológicos, sicológicos, económicos y sociales que se observan durante el envejecimiento conllevan a pensar que en los ancianos existe una serie de factores que favorecen la aparición de una depresión. Objetivo: evaluar la efectividad de una intervención sicológica para disminuir la depresión en adultos mayores de la Casa de abuelos "Dr. Diego Tamayo Figueredo", de Puerto Padre, en el período de noviembre de 2013 - mayo de 2014. Material y métodos: se realizó un estudio de intervención sicológica (...) en una muestra de 12 adultos mayores de la casa de abuelos. Se aplicó un programa de intervención sicológica, así como la Escala de Depresión Geriátrica para realizar la valoración antes y después de la intervención. Se empleó el modelo Cognitivo- Conductual de Beck. Los datos fueron tratados según la estadística descriptiva. Resultados: el porciento más elevado de pacientes correspondió al grupo de ancianos con edades entre los 60 y 90 años de edad. Respecto al sexo, el más frecuente es el masculino. El asma bronquial, la hipertensión arterial y la diabetes Mellitus representaron el mayor porciento de antecedentes patológicos personales. Conclusión: la intervención sicológica resultó efectiva pues se logró disminuir a leve los niveles iniciales de depresión establecida y los considerados con leve a no depresión, por lo tanto se afirma que con su aplicación fue modificado el estado emocional de los adultos mayores que se implicaron en la muestra. Introduction: Biological, psychological, financial and social changes observed during aging lead to think that there is a series of factors that favor the appearance of depression in senior citizens. Objective: Assessing the effectiveness of a psychological intervention in order to reduce depression in senior citizens from "Dr. Diego Tamayo Figueredo" Senior Citizens' House, Puerto Padre, from November 2013 to May 2014. Material and methods: A psychological intervention study was conducted on a sample of 12 senior citizens from the house. A psychological intervention program as well as the Geriatrics Depression Scale were applied before and after the intervention in order to make the assessment. The Beck's cognitive-behavior model was used. Data was processed according to descriptive statistics. Results: The highest percentage of patients corresponded to a group of seniors between 60 and 90 years of age. Regarding sex, males are more common. Bronchial asthma, arterial hypertension and diabetes mellitus represented the highest percentage of personal pathological history. Conclusion: The psychological intervention proved to be effective since initial established depression levels were reduced to minor and those considered as minor were reduced to no depression ; therefore, it is stated that its application modified the state of mind of the senior citizens involved in the sample.

Rodger et al have interestingly argued that xenotransplantation should, if possible, entail the use of genetic pain disenhancement to prevent otherwise unavoidable pain in ‘donor’ animals.1 Their argument relies on the empirical assumption that xenotransplantation offers a realistic solution to organ shortage, and that, due to the recent clinical developments and the lack of human donors, it will thus continue for the foreseeable future. We argue below that other options should be prioritised over xenotransplantation, and that so-called ‘non-sentientist’ harms are (...) undervalued in discussions on disenhancement. We do not challenge the empirical claim made by the authors. That is, xenotransplantation research might continue for the foreseeable future since organ demand is increasing. However, we disagree with the priority given to xenotransplantation over other solutions that are more morally desirable. We argue that, if we comply with the 3R principles (Replacement, Reduction, and Refinement of the use of animals in research) and follow a minimal welfarist reasoning (to which the authors seem to adhere), then (1) the principle of replacement demands the use of non-animal alternatives if possible and (2) there are alternative solutions that lead to morally better consequences. Schematically, there are …. (shrink)

The ethics of deceased organ procurement (OP) is supposedly based on individual consent to donate, either explicit (opt-in) or presumed (opt-out). However, in many cases, individuals fail to express any preference regarding donation after death. When this happens, the decision to remove or not to remove their organs depends on the policy’s default option or on family preferences. Several studies show that in most countries the family plays a significant and often decisive role in the process of decision-making for OP. (...) Depending on the country, the family may be allowed to take different kinds of actions in different situations, and this may be granted either by law or by clinical practice only. This adds much complexity to the usual classification of consent policies in two categories: opt-in and opt-out. Here we propose a novel and comprehensive taxonomy of the models of consent for OP according to three variables: (1) the deceased’s wishes, if any, (2) family wishes, if any, and (3) default policies. By analysing these models of consent, we show that they rely on at least three different concepts of autonomy: individual autonomy, relational autonomy, and family autonomy. In light of this analysis, we discuss the ethical debates surrounding two policy approaches: presumed consent and family veto. (shrink)

Background: Several countries have recently changed their model of consent for organ donation from opt-in to opt-out. We undertook a systematic review to determine public knowledge and attitudes towards these models in Europe. Methods: Six databases were explored between 1 January 2008 and 15 December 2017. We selected empirical studies addressing either knowledge or attitudes towards the systems of consent for deceased organ donation by lay people in Europe, including students. Study selection, data extraction, and quality assessment were conducted by (...) two or more reviewers independently. Findings: Awareness of the consent model was lower in opt-out countries than in opt-in countries. A majority of the public agrees with opt-in, regardless of the law in their own country. There are ambivalent attitudes regarding the opt-out system. The public tend to prefer opt-in and mandatory choice over opt-out when several options are offered. Interpretation: The assumption that people in opt-out countries are aware of the legal requirements to be excluded from the pool of potential donors is not supported by the results of this review. This is a concern, since ignorance hinders people's autonomy regarding organ donation decision-making. Higher awareness of consent model in opt-in countries may reflect greater efforts to inform the public through campaigns to motivate donation. Legal moves towards opt-out are at odds with people's expressed preferences. Main limitations of this review are the lack of data from some countries, study population heterogeneity, and methodological shortcomings. (shrink)

Since 1968, the irreversible loss of functioning of the whole brain, called brain death, is assimilated to individual’s death. The almost universal acceptance of this neurological criterion of death had decisive consequences for the contemporary medicine, such as the withdrawal of mechanical ventilation in these patients and organ retrieval for transplantation. The new criterion was successfully accepted in part because the assimilation of brain death state to death was presented by medicine --and acritically assumed by most of societies-- as a (...) scientific and objective fact. Nevertheless, many people do not think that the patients suffering brain death are actually dead. We show here that those people are not necessarily wrong. It can be argued that, in fact, the justification of the neurological criterion is not scientific but moral. We outline the thesis that the problem surrounding the vital status of brain dead patients is due to a confusion between factual and normative questions. Furthermore, we claim that the donation of organs and the withdrawal of life-support could be ethically acceptable even if the patients suffering brain death are considered as alive. As an alternative to the dead donor rule, we propose a justification for organ donation of brain-dead patients based on the (moral) concepts of harm and consent : what truly justifies the procurement of organs on those patients is not that they are dead, but that they wish to donate their organs and that, since they have irreversibly lost their brain, they cannot be harmed.

This article captures and critiques a recurring and prominent political argument against animal welfare improvements in Switzerland which we term the “ranking argument”. This states that Swiss animal welfare law ranks among the strictest in the world, therefore no improvements are called for. This argument was advanced three times by Swiss government authorities in 2022 alone, but also in a case dating back to 1984, to advise the electorate on popular initiatives aiming at animal welfare improvements. We argue that, while (...) the argument commits a fallacy of relative privation and is ethically dubious, it can be deployed to great effect by agents opposed to norm change in animal welfare regulation. We conclude with some thoughts on how the ranking argument can and should be challenged in public discourse. (shrink)

Taking the Critique of Judgement for an answer to the problem raised by the kantian dualisms, I offer a reading of this work according to which in the part devoted to the teleological judgement Kant practices a Hegelian way of resolution, whereas, in the “critique of the aesthetic judgement”, he thinks the relation between the opposites of such dualisms in a new way that opens up the possibility of a dialectical thought rid of the absolutness of the Hegelian reason.

Although research on the corporate social responsibility (CSR) dimension of corporate image has notably increased in recent years, the definition and measurement of the concept for academic purposes still concern researchers. In this article, literature regarding the measurement of CSR image from a customer viewpoint is revised and areas of improvement are identified. A multistage method is implemented to develop and to validate a reliable scale based on stakeholder theory. Results demonstrate the reliability and validity of this new scale for (...) measuring customer perceptions regarding the CSR performance of their service providers. With regard to this, CSR includes corporate responsibilities towards customers, shareholders, employees and society. The scale is consistent among diverse customer cohorts with different gender, age and level of education. Furthermore, results also confirm the applicability of this new scale to structural equation modelling. (shrink)

How should automated vehicles (AVs) react in emergency circumstances? Most research projects and scientific literature deal with this question from a moral perspective. In particular, it is customary to treat emergencies involving AVs as instances of moral dilemmas and to use the trolley problem as a framework to address such alleged dilemmas. Some critics have pointed out some shortcomings of this strategy and have urged to focus on mundane traffic situations instead of trolley cases involving AVs. Besides, these authors rightly (...) point out the political nature of the most interesting debates involving AVs. However, in our view, they do not offer an adequate account of the distinction between ethics and politics and still see their proposals as contributions to the ethics of AVs. We argue that many of the interesting questions about how AVs should behave, both in emergency and other situations, are of political, and not moral, nature. This view is based on a conception of politics and political normativity that we have developed elsewhere and that we call “political minimalism.” Additionally, we show that this proposed perspective has significant consequences for the design, management, and regulation of transport systems.

The study here is a qualitative research based on multiple case studies of banking service providers to analyze the role of corporate social responsibility (CSR) in the definition of the corporate identity of these kinds of organizations.

These results have important implications for those managers pursuing (...) an effective management of CSR policies and strategies in their organizations, especially as the information comes from 6 of the biggest and most important banking institutions in a European country, with a declared assets (loans) volume which represents 62.75% of the total assets in the national banking industry, and thus largely representing the possible heterogeneity of the market in terms of company size, location, legal status, and management styles.

Objectives To increase postmortem organ donation rates, several countries are adopting an opt-out (presumed consent) policy, meaning that individuals are deemed donors unless they expressly refused so. Although opt-out countries tend to have higher donation rates, there is no conclusive evidence that this is caused by the policy itself. The main objective of this study is to better assess the direct impact of consent policy defaults per se on deceased organ recovery rates when considering the role of the family in (...) the decision-making process. This study does not take into account any indirect effects of defaults, such as potential psychological and behavioural effects on individuals and their relatives. -/- Design Based on previous work regarding consent policies, we created a conceptual model of the decision-making process for deceased organ recovery that included any scenario that could be directly influenced by opt-in or opt-out policies. We then applied this model to internationally published data of the consent process to determine how frequently policy defaults could apply. -/- Main outcome measures We measure the direct impact that opt-in and opt-out policies have per se on deceased organ recovery. -/- Results Our analysis shows that opt-in and opt-out have strictly identical outcomes in eight out of nine situations. They only differ when neither the deceased nor the family have expressed a preference and defaults therefore apply. The direct impact of consent policy defaults is typically circumscribed to a range of 0%–5% of all opportunities for organ recovery. Our study also shows that the intervention of the family improves organ retrieval under opt-in but hinders it under opt-out. -/- Conclusions This study may warn policy makers that, by emphasising the need to introduce presumed consent to increase organ recovery rates, they might be overestimating the influence of the default and underestimating the power granted to families.

The debate over the determination of death has been raging for more than fifty years. Since then, objections against the diagnosis of brain death from family members of those diagnosed as dead-have been increasing and are causing some countries to take novel steps to accommodate people’s beliefs and preferences in the determination of death. This, coupled with criticism by some academics of the brain death criterion, raises some questions about the issues surrounding the determination of death. In this paper, we (...) discuss some of the main approaches to death determination that have been theoretically proposed or currently put into practice and propose a new approach to death determination called "weak pluralism" as a reasonable ethical and political alternative to respect diversity in death determination.

Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...) Austria (AT), Belgium (BE), Denmark (DK), Germany (DE), Greece (GR), Slovenia (SI) and Spain (ES), asking participants about their donation preferences, as well as their beliefs and views about the policy in place. From these measures, we computed indices of informedness, policy support, and fulfilment of unexpressed preferences, which we compared across countries and consent systems. -/- Results Our study introduces a tool for analyzing policy governance in the context of OP. Wide variation in policy awareness was observed: Most respondents in DK, DE, AT and BE correctly identified the policy in place, while those in SI, GR and ES did not. Respondents in opt-out countries (AT, BE, ES and GR) tended to support the policy in place (with one exception, i.e., SI), whereas those in opt-in countries (DE and DK) overwhelmingly opposed it. These results reveal stark differences in governance quality across countries and consent policies: We found a preponderance of informed opposition in opt-in countries and a general tendency towards support–either informed or uninformed–in opt-out countries. We also found informed divergence in opt-in countries and a tendency for convergence–either informed or uninformed–among opt-out countries. -/- Conclusion Our study offers a novel tool for analyzing governance quality and illustrates, in the context of OP, how the strengths and weaknesses of different policy implementations can be estimated and compared using quantitative survey data.

Recently, organizational identity is being given more attention than ever before in the business world. This notion has grown substantially in importance in the hospitality industry. Facing increased competition, hospitality companies are driven to project a positive image to their stakeholders. Therefore, these organizations have begun to develop new organizational identity programs as part of their strategies to achieve their desired identities. This study analyzes the role of corporate social responsibility in the definition of the Organizational Identity of these organizations, (...) employing a qualitative research methodology based on an illustrative case study. Particularly, the authors analyze the case of Meliá Hotels International, a leading hotel company in Spain with a presence in 27 countries. The findings indicate that the company has formally integrated CSR into its strategy to align its actual identity with its desired and conceived identity in view of the critics in its local community. Moreover, the interest of the firm toward its stakeholders suggests that the company understands its conceived identity as an important link in understanding its organizational identity. This paper demonstrates that firm’s organizational identity is a set of several elements. When analyzing Meliá Hotels International’s identity, we see that the firm defines this concept as that which is most central, enduring, and distinctive about the organization. In this sense, the company appears to follow the vision-driven approach by referring to the organizational mission and vision statements, organizational philosophy, and core values as the basis of organizational identity.

Families play an essential role in deceased organ procurement. As the person cannot directly communicate his or her wishes regarding donation, the family is often the only source of information regarding consent or refusal. We provide a systematic description and analysis of the different roles the family can play, and actions the family can take, in the organ procurement process across different jurisdictions and consent systems. First, families can inform or update healthcare professionals about a person’s donation wishes. Second, families (...) can authorize organ procurement in the absence of deceased’s preferences and the default is not to remove organs, and oppose donation where there is no evidence of preference but the default is to presume consent; in both cases, the decision could be based on their own wishes or what they think the deceased would have wanted. Finally, families can overrule the known wishes of the deceased, which can mean preventing donation, or permitting donation when the deceased refused it. We propose a schema of 4 levels on which to map these possible family roles: no role, witness, surrogate, and full decisional authority. We conclude by mapping different jurisdictions onto this schema to provide a more comprehensive understanding of the consent system for organ donation and some important nuances about the role of families. This classificatory model aims to account for the majority of the world’s consent systems. It provides conceptual and methodological guidance that can be useful to researchers, professionals, and policymakers involved in organ procurement. (shrink)

Besides, multiobjective optimization on the basis of ratio analysis is utilized to choose the best alternatives. Finally, two decision-making problems are applied to illustrate the feasibility and practicality of the proposed method. (shrink)

To address this issue, a series of mechanisms are proposed, supported by evidence from different fields, by which CD38 overexpression can facilitate CD4 T cell depletion in HIV infection. According to this model, increased catalytic activity of CD38 may reduce CD4 T cells’ cytoplasmic nicotin‐amide adenine dinucleotide (NAD), leading to a chronic Warburg effect. This will reduce mitochondrial function. Simultaneously, CD38's (...) catalytic products ADPR and cADPR may be transported to the cytoplasm, where they can activate calcium channels and increase cytoplasmic Ca2+ concentrations, further altering mitochondrial integrity. These mechanisms will decrease the viability and regenerative capacity of CD4 T cells. These hypotheses can be tested experimentally, and might reveal novel therapeutic targets. (shrink)
