In recent decades, many jurisdictions have moved toward legalizing euthanasia and assisted suicide, alongside a near-universal increase in public acceptance of medical aid in dying. Here, we draw on a comprehensive quantitative review of current laws on assisted dying, experimental survey evidence, and four decades of time-series data to explore the relationship between these legislative transitions and change in moral attitudes. Our analyses reveal that existing laws on medical aid in dying impose a common set of eligibility restrictions, based on the patient's age, decision-making capacity, prognosis, and the nature of their illness. Fulfillment of these eligibility criteria elevates public moral approval of physician-assisted death, equally in countries with (i.e., Spain) and without (i.e., the United Kingdom) assisted dying laws. Finally, historical records of public attitudes toward euthanasia across numerous countries uncovered anticipatory growth in moral approval leading up to legalization, but no accelerated growth thereafter. Taken together, our findings suggest that the enactment of medical aid in dying laws, and their specific provisions, crystallize patterns in moral intuition., Competing Interests: Competing interests statement:The authors declare no competing interest.

Almost a year after the enactment of the law regulating euthanasia in Spain, public opinion was shocked to learn that a defendant in criminal proceedings obtained medical assistance in dying following injuries sustained in an exchange of gunfire with the police after having committed a series of severe crimes. Although there are very few cases in the world where prisoners have received euthanasia, the one we will discuss in this article is the only known case where both the public prosecutor's office and the private prosecutors judicially opposed the defendant's euthanasia. This article aims to offer a new perspective on the ethical legitimacy of detainees' access to euthanasia: the ethics of caring solidarity. To do this, we will first place the case in its legal context. Subsequently, we will address the two main arguments proposed in the literature to justify euthanasia in detention: respect for the autonomy of the detainee and the principle of equivalence of care. Finally, after having identified serious shortcomings in both arguments, we will argue that the perspective of caring solidarity offers a better ethical basis for people in detention's access to euthanasia., (© 2024 The Author(s).

Colombia was one of the first countries to decriminalise euthanasia. However, what is known in the international academic literature about the country's regulations is scarce and outdated. Such lack of information on the situation in Latin America is even more evident in the case of Peru, where the Lima Superior Court of Justice set a precedent by allowing a person to have access to euthanasia in 2021. Ecuador, which has just decriminalised euthanasia for all its citizens in February 2024, risks being similarly absent from the international dialogue. This article summarises for the first time all the regulations in force regarding euthanasia in Latin America, through a study of primary sources in Spanish, and analyses some of the convergences between these three neighbouring countries., (© 2024 John Wiley & Sons Ltd.)

Purpose: Spontaneous cataracts have been identified in the lenses of animals across a phylogenetically wide range of species. This can be a source of insights and innovation for human health professionals, but many persons may lack awareness of it. By providing a phylogenetic survey and analysis of species with cataract vulnerability, this paper demonstrates how a broad comparative perspective can provide critical information about environmental hazards to human visual health and can spark potential innovations in the prevention and treatment of cataracts in humans., Design: Perspectives., Methods: Review and synthesis of selected literature with interpretation and perspective., Results: We found 273 recorded cases of spontaneously occurring cataracts in 113 species of birds, 83 species of mammals, 30 species of actinopterygii fish, 10 species of amphibians, 6 species of reptiles, and 1 species of cephalopod., Conclusion: A phylogenetically wide range of species, including many living in and around human environments, are vulnerable to cataracts. These animals may serve as sentinels for human visual health. Variation in cataract vulnerability across species may also facilitate the identification of resistance-conferring physiologies, leading to accelerated innovation in the prevention and treatment of cataracts in humans., (Copyright © 2023 Elsevier Inc.

Ecological and evolutionary processes govern the fitness, propagation, and interactions of organisms through space and time, and viruses are no exception. While coronavirus disease 2019 (COVID-19) research has primarily emphasized virological, clinical, and epidemiological perspectives, crucial aspects of the pandemic are fundamentally ecological or evolutionary. Here, we highlight five conceptual domains of ecology and evolution - invasion, consumer-resource interactions, spatial ecology, diversity, and adaptation - that illuminate (sometimes unexpectedly) the emergence and spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We describe the applications of these concepts across levels of biological organization and spatial scales, including within individual hosts, host populations, and multispecies communities. Together, these perspectives illustrate the integrative power of ecological and evolutionary ideas and highlight the benefits of interdisciplinary thinking for understanding emerging viruses., Competing Interests: Declaration of Interests There are no interests to declare., (Copyright © 2021 Elsevier Ltd.

Physical examination is essential in diagnosing tendinous lesions. This is particularly true of the flexor digitorum superficialis of the little finger (FDS5), which is functionally absent in approximately 30% of the population. The objective of our study was to determine the diagnostic value of 3 clinical tests commonly used to assess the function of this tendon., Methods: Patients with wounds of the FDS5 were included in this study. Under local or regional anesthesia, 3 described clinical tests were performed to assess the function of the FDS5: (i) the classic test; (ii) Stein's modified test, and (iii) Mecott's modified test. We determined sensitivity, specificity, and predictive values of all such tests. The integrity of the tendon was assessed surgically. Correlation among blinded observers was also established., Results: A total of 28 subjects with a mean age of 28 years (ranging from 5 to 56) participated in this study. The classic test obtained a sensitivity of 100% and a specificity of 72%; Stein's test resulted in a sensitivity of 83% and a specificity of 95%, whereas Mecott's test reached a sensitivity of 100% and a specificity of 95%., Conclusions: Among the 3 tests described and used in our study, Mecott's modified test proved to be more sensitive and specific than the other two; therefore, we consider this to be the test that should be used in determining the integrity of the FDS5.
