RESUMO
Forensic science is undergoing an evolution in which a long-standing "trust the examiner" focus is being replaced by a "trust the scientific method" focus. This shift, which is in progress and still partial, is critical to ensure that the legal system uses forensic information in an accurate and valid way. In this Perspective, we discuss the ways in which the move to a more empirically grounded scientific culture for the forensic sciences impacts testing, error rate analyses, procedural safeguards, and the reporting of forensic results. However, we caution that the ultimate success of this scientific reinvention likely depends on whether the courts begin to engage with forensic science claims in a more rigorous way.

Research Highlight: Jachowski, D. S., Marneweck, C. J., Olfenbuttel, C., & Harris, S. N. (2024). Support for the size-mediated sensitivity hypothesis within a diverse carnivore community. Journal of Animal Ecology, https://doi.org/10.1111/1365-2656.13916. A current paradigm in ecological research suggests that top predators are suitable sentinel species to identify ecosystem dysfunctions and monitor the effects of climate change. However, the adequacy of top predators to systematically take this function may be mistakenly inferred or unintentionally conflated from the fact that these species are regarded as biodiversity indicators or keystone, umbrella and flagship species in most ecosystems. Regarding terrestrial mammalian carnivores (order Carnivora), some researchers recently suggested that the smaller species likely possess a higher sensitivity to environmental changes than large carnivores because of their biological attributes and their intermediate position in food webs. To test this hypothesis, Jachowski et al. (2024) used camera trapping followed by occupancy and structural equation modelling to explore the dynamics of a diverse carnivore community and the factors that influence them. Their results confirmed that small carnivores are more sensitive to habitat changes and are interconnected by a greater number of significant pathways compared with larger carnivores. This support for the size-mediated sensitivity hypothesis strengthens the proposition that small carnivores (and other mid-rank predators) are ideal sentinel species for monitoring the effects of the wide range of contemporary and future environmental changes. Time will tell whether this new 'middle-out ecology' paradigm will be considered in future global change studies.

Recent investigations with non-model species and whole-genome approaches have challenged several paradigms in animal epigenetics. They revealed that epigenetic variation in populations is not the mere consequence of genetic variation, but is a semi-independent or independent source of phenotypic variation, depending on mode of reproduction. DNA methylation is not positively correlated with genome size and phylogenetic position as earlier believed, but has evolved differently between and within higher taxa. Epigenetic marks are usually not completely erased in the zygote and germ cells as generalized from mouse, but often persist and can be transgenerationally inherited, making them evolutionarily relevant. Gene body methylation and promoter methylation are similar in vertebrates and invertebrates with well methylated genomes but transposon silencing through methylation is variable. The new data also suggest that animals use epigenetic mechanisms to cope with rapid environmental changes and to adapt to new environments. The main benefiters are asexual populations, invaders, sessile taxa and long-lived species.

Ketosis is currently regarded as a major metabolic disorder of dairy cows, reflective of the animal's efforts to adapt to energy deficit while transitioning into lactation. Currently viewed as a pathology by some, ketosis is associatively implicated in milk production losses and peripartal health complications that increase the risk of early removal of cows from the herd, thus carrying economic losses for dairy farmers and jeopardizing the sustainability of the dairy industry. Despite decades of intense research in the mitigation of ketosis and its sequelae, our ability to lessen its purported effects remains limited. Moreover, the association of ketosis to reduced milk production and peripartal disease is often erratic and likely mired by concurrent potential confounders. In this review, we discuss the potential reasons for these apparent paradoxes in the light of currently available evidence, with a focus on the limitations of observational research and the necessary steps to unambiguously identify the effects of ketosis on cow health and performance via controlled randomized experimentation. A nuanced perspective is proposed that considers the dissociation of ketosis-as a disease-from healthy hyperketonemia. Furthermore, in consideration of a growing body of evidence that highlights positive roles of ketones in the mitigation of metabolic dysfunction and chronic diseases, we consider the hypothetical functions of ketones as health-promoting metabolites and ponder on their potential usefulness to enhance dairy cow health and productivity.

The current changes to the treatment recommendations and the diagnostic categorization of trans* identities in the ICD-11 require a new consideration of past therapeutic methods and approaches. The depathologization of trans* lives in the ICD-11 finally enables trans* people to access psychotherapeutic services more freely, as the compulsory therapy that has thus far been required for access to transition-related treatments, as well as the so-called "diagnosis" and "treatment" of "transsexuality", have been removed. Trans* people will nevertheless be interested in qualified psychotherapeutic treatment options. Due to the decades-long discrimination and treatment in the health system that has disregarded the human rights of trans* people, a trans*-affirmative approach is necessary, one that takes into account the context of the treatment and critically reflects upon one's own position as a health professional. This affirmative and self-reflective approach provides the basis upon which therapeutic concerns and topics related to a life lived in accordance with a self-determined (gender) identity, related needs, and the fulfillment of those needs, can be discussed. The consequences of experiences of discrimination, violence and exclusion are, moreover, important elements of therapy that require a structural and social contextualization in order to address internalized trans*-negativity and to empower trans* people in their self-assertion.
RESUMO
Amid the increasing demand for palliative care, driven by demographic shifts and medical progress, evidence-based practices face obstacles due to limited research. Complex patient conditions and ethical considerations challenge traditional methodologies, while the absence of comprehensive clinical trials hinders innovative interventions. Empowering practitioners with research skills and establishing a palliative care research network are efforts aimed at bridging these gaps. It is important to emphasise that these initiatives collectively aspire to enhance evidence-based practices, ensuring quality care for individuals facing severe illnesses.
RESUMO
BACKGROUND: This work elucidates the first cellular and molecular causes of cataractogenesis. Current paradigm presupposes elevated blood glucose as a prerequisite in diabetic cataractogenesis. Novel evidence in our model of diabetic cataract challenges this notion and introduces immune cell migration to the lens and epithelial-mesenchymal transformation (EMT) of lens epithelial cells (LECs) as underlying causes. METHODS: Paucity of suitable animal models has hampered mechanistic studies of diabetic cataract, as most studies were traditionally carried out in acutely induced hyperglycemic animals. We introduced diabetic cataract in the Nile grass rat (NGR) that spontaneously develops type 2 diabetes (T2D) and showed its closeness to the human condition. Specialized stereo microscopy with dual bright-field illumination revealed novel hyperreflective dot-like microlesions in the inner cortical regions of the lens. To study immune cell migration to the lens, we developed a unique in situ microscopy technique of the inner eye globe in combination with immunohistochemistry. RESULTS: Contrary to the existing paradigm, in about half of the animals, the newly introduced hyper reflective dot-like microlesions preceded hyperglycemia. Even though the animals were normoglycemic, we found significant changes in their oral glucose tolerance test (OGTT), indicative of the prediabetic stage. The microlesions were accompanied with significant immune cell migration from the ciliary bodies to the lens, as revealed in our novel in situ microscopy technique. Immune cells adhered to the lens surface, some traversed the lens capsule, and colocalized with apoptotic nuclei of the lens epithelial cells (LECs). Extracellular degradations, amorphous material accumulations, and changes in E-cadherin expressions showed epithelial-mesenchymal transformation (EMT) in LECs. Subsequently, lens fiber disintegration and cataract progression extended into cortical, posterior, and anterior subcapsular cataracts. CONCLUSIONS: Our results establish a novel role for immune cells in LEC transformation and death. The fact that cataract formation precedes hyperglycemia challenges the prevailing paradigm that glucose initiates or is necessary for initiation of the pathogenesis. Novel evidence shows that molecular and cellular complications of diabetes start during the prediabetic state. These results have foreseeable ramifications for early diagnosis, prevention and development of new treatment strategies in patients with diabetes.

Regulatory science, rooted in legal requirements, provides a mechanism for identifying, assessing, and managing harm to humans and the environment from exposure to hazardous substances. A challenge for regulatory authorities is that many governing laws reflect the scientific paradigm of the mid-20th century. By the nature of legislative processes, most laws are not able to readily adapt to incorporate scientific advances that are inherent in an ever-evolving paradigm. Consequently, the issue of rigid legal frameworks has become prominent in global discussions related to the incorporation of reliable and relevant modern technology to fulfill regulatory needs. To explore this issue, we apply Thomas Kuhn's The Structure of Scientific Revolutions as a conceptual framework to help understand the natural progression of scientific paradigms (from normal science, to anomaly, to crisis, to revolution, and finally to a new normal), identify where we are now in the paradigm cycle, and to explore a path towards a revolution that enables timely implementation of the best available science to fulfil legal requirements.

The so-called "empirical turn" in bioethics gave rise to extensive theoretical and methodological debates and has significantly shaped the research landscape from two decades ago until the present day. Attentive observers of the evolution of the bioethical research field now notice a new trend towards the inclusion of data science methods for the treatment of ethical research questions. This new research domain of "digital bioethics" encompasses both studies replacing (or complementing) socio-empirical research on bioethical topics ("empirical digital bioethics") and argumentative approaches towards normative questions in the healthcare domain ("argumentative digital bioethics"). This article draws on insights taken from the debate on the "empirical turn" for sounding out perspectives for the newly developing field of "digital bioethics." We particularly discuss the disciplinary boundaries, chances and challenges, and potentially undesirable developments of the research field. The article closes with concrete suggestions on which debates need to be initiated and which measures need to be taken so that the path forward of "digital bioethics" will be a scientific success.

Our problem-oriented approach to health care, though historically reasonable and undeniably impactful, is no longer well matched to the needs of an increasing number of patients and clinicians. This situation is due, in equal parts, to advances in medical science and technologies, the evolution of the health care system, and the changing health challenges faced by individuals and societies. The signs and symptoms of the failure of problem-oriented care include clinician demoralization and burnout; patient dissatisfaction and non-adherence; overdiagnosis and labeling; polypharmacy and iatrogenesis; unnecessary and unwanted end-of-life interventions; immoral and intolerable disparities in both health and health care; and inexorably rising health care costs. A new paradigm is needed, one that humanizes care while guiding the application of medical science to meet the unique needs and challenges of individual people. Shifting the focus of care from clinician-identified abnormalities to person-relevant goals would elevate the role of patients; individualize care planning; encourage prioritization, prevention, and end-of-life planning; and facilitate teamwork. Paradigm shifts are difficult, but the time has come for a reconceptualization of health and health care that can guide an overdue transformation of the health care system.

We aim to consolidate recent trends in public health into a reconceptualization of the field as public good. We build on several strands of theory, research and action to formulate a more impactful future for the field. Our argument comprises three main parts. In the first part, we describe the central components of the proposed public good: conditions of justice, experiences of mattering, and outcomes of subjective and objective wellbeing. In the second section, we identify continua of practices that paint a trajectory from traditional public health to ecological and participatory public health, to universal wellbeing framed as a public good. The continua are defined in terms of assumptions, practices and roles. Among others, these continua pertain to capabilities, scope of the field, ecological focus, timing of intervention, role of citizen, role of professional, role of settings and role of government. Finally, the third section introduces a series of strategies and recommendations to make the narrative of universal wellbeing as public good a reality.

Nature-based Solutions (NbS) are promoted as practical and theoretical solutions that simultaneously provide human well-being and biodiversity benefits. One example is soil bioengineering using construction techniques based on living vegetation, and is frequently used for riverbank stabilization, flood protection, and erosion control. Compared with civil engineering, NbS offer many advantages such as cost reduction, limited impact on the environment, and production of ecosystem services. However, their use is still marginal for riverbank control, especially in urban areas. In this paper, we focus on soil bioengineering techniques for riverbank protection in an urban context from the practitioners' perspective. We question to what extent NbS require a shift in management paradigm. We used qualitative methods to interview 17 practitioners working in the Rhone Alps basin (France). Our results reveal that switching from civil engineering to soil bioengineering is not only a technical change, but also requires a shift from a "predict and control" paradigm to an "adaptive management" paradigm because of three major reasons. First, soil bioengineering techniques require redefinition of the performance of engineering structures with the inclusion of ecological and social dimensions. Second, the adoption of soil bioengineering techniques requires that practitioners, elected people and inhabitants reconsider risk sharing and acceptance. Third, the techniques require practitioners to adopt a new posture, with new soft skills (humility and daring) and a new collective organization (collective feedback). Finally, we identify three levers for a broader use of such techniques: (i) systematic assessment of the ecological, economical, and social benefits of such techniques; (ii) improving risk acceptance and sharing; (iii) fostering of social learning among practitioners through collective or technical feedback.

BACKGROUND: Albeit primarily a disease of respiratory tract, the 2019 coronavirus infectious disease (COVID-19) has been found to have causal association with a plethora of neurological, neuropsychiatric and psychological effects. This review aims to analyze them with a discussion of evolving therapeutic recommendations. METHODS: PubMed and Google Scholar were searched from 1 January 2020 to 30 May 2020 with the following key terms: "COVID-19", "SARS-CoV-2", "pandemic", "neuro-COVID", "stroke-COVID", "epilepsy-COVID", "COVID-encephalopathy", "SARS-CoV-2-encephalitis", "SARS-CoV-2-rhabdomyolysis", "COVID-demyelinating disease", "neurological manifestations", "psychosocial manifestations", "treatment recommendations", "COVID-19 and therapeutic changes", "psychiatry", "marginalised", "telemedicine", "mental health", "quarantine", "infodemic" and "social media". A few newspaper reports related to COVID-19 and psychosocial impacts have also been added as per context. RESULTS: Neurological and neuropsychiatric manifestations of COVID-19 are abundant. Clinical features of both central and peripheral nervous system involvement are evident. These have been categorically analyzed briefly with literature support. Most of the psychological effects are secondary to pandemic-associated regulatory, socioeconomic and psychosocial changes. CONCLUSION: Neurological and neuropsychiatric manifestations of this disease are only beginning to unravel. This demands a wide index of suspicion for prompt diagnosis of SARS-CoV-2 to prevent further complications and mortality.
Les impacts neurologiques et neuropsychiatriques d'une infection à la COVID-19. CONTEXTE: Bien qu'il s'agisse principalement d'une maladie des voies respiratoires, la maladie infectieuse à coronavirus apparue en 2019 (COVID-19) s'est avérée avoir un lien de causalité avec une pléthore d'impacts d'ordre neurologique, neuropsychiatrique et psychologique. Cette étude entend donc analyser ces impacts tout en discutant l'évolution des recommandations thérapeutiques se rapportant à cette maladie. MÉTHODES: Les bases de données PubMed et Google Scholar ont été interrogées entre les 1er janvier et 30 mai 2020. Les termes clés suivants ont été utilisés : « COVID-19 ¼, « SRAS CoV-2 ¼, « Pandémie ¼, « Neuro COVID ¼, « AVC COVID ¼, « Épilepsie COVID ¼, « COVID encéphalopathie ¼, « SRAS CoV-2 encéphalite ¼, « SRAS CoV-2 rhabdomyolyse ¼, « COVID maladie démyélinisante ¼, « Manifestations neurologiques ¼, « Manifestations psychosociales ¼, « Recommandations thérapeutiques ¼, « COVID-19 et changement thérapeutiques ¼, « Psychiatrie ¼, « Marginalisés ¼, « Télémédecine ¼, « Santé mentale ¼, « Quarantaine ¼, « Infodémique ¼ et « Médias sociaux ¼. De plus, quelques articles de journaux relatifs à la pandémie de COVID-19 et à ses impacts psychosociaux ont également été ajoutés en fonction du contexte. RÉSULTATS: Il appert que les manifestations neurologiques et neuropsychiatriques des infections à la COVID-19 sont nombreuses. Les caractéristiques cliniques d'une implication des systèmes nerveux central et périphérique sautent désormais aux yeux. Ces caractéristiques ont fait l'objet d'une brève analyse systématique à l'aide de publications scientifiques. En outre, la plupart des impacts d'ordre psychologique de cette pandémie se sont révélés moins apparents que les changements réglementaires, socioéconomiques et psychosociaux. CONCLUSION: Les manifestations neurologiques et neuropsychiatriques de cette maladie ne font que commencer à être élucidées. Cela exige donc une capacité accrue de vigilance en vue d'un diagnostic rapide, et ce, afin de prévenir des complications additionnelles et une mortalité accrue.

In 1992, Norm Sauer called for a language shift in which practitioners would move away from the socially loaded term "race" and replace it with the less provocative term "ancestry." While many heeded the call and moved towards ancestry in their research and reports, the actual approach to research and analysis did not change. In response to this change, there was a large growth in ancestry estimation method development in the early decade of the 2000s. However, the practice of ancestry estimation did not adequately incorporate evolutionary theory in interpretation or trait selection and continued with little critical reflection. In the past decade, there has been an increase in ancestry validation methods with little critique of the "race" concept or discussion of modern human variation or reference samples. To advance, forensic anthropologists need to reckon with the practice of ancestry estimation as it is currently practiced. We are calling for another reform in the axiom focusing on evolutionary theory, population history, trait selection, and population-level reference samples. The practice needs to abandon the terms ancestry and race completely and recalibrate to an analysis of population affinity. Population affinity is a statistical approach based on the underlying population structure that would allow the understanding of how microevolutionary forces act in concert with historical events (e.g., colonization, the Transatlantic Slave Trade, etc.) to shape modern human variation. This is not to be confused with geographic ancestry that all too often can be perceived as interchangeable with social race and as an affirmation of the biological concept of race. It is time to critically evaluate the social and scientific implications of the current practice of ancestry estimation, and re-frame our approach to studying and analyzing modern human variation through a population structure approach.

The rapidity with which vaccines against COVID-19 have been developed and tested is unprecedented. As classically the case with randomized clinical trials, many studies excluded older adults. However, given the early realisation that senior citizens were most highly susceptible to COVID, older individuals have been included in licensing trials under these unusual conditions. The recently published results from the Comirnaty Vaccine (BNT162b) trial unexpectedly documented that vaccine efficacy was equally exceptionally high in older and younger adults. These extremely encouraging trial results with a neoantigen vaccine may suggest the beginning of a paradigm shift in our view of the impact of immunosenescence on vaccination against novel infectious diseases.
RESUMO
Therapeutics and vaccines against the COVID-19 pandemic need to be developed rapidly and efficiently, given its severity. To maximize the efficiency and productivity of drug development, the world has adopted disruptive technologies and approaches in various drug development areas. Telehealth, characterized by the heavy use of digital technologies; drug repositioning strategies, aided by computational breakthroughs; and data tracking tool hubs, enabling real-time information sharing, have received much attention. Moreover, drug developers have engaged in open innovation by establishing various types of collaborations, many of which have been carried out across nations and enterprises. Finally, regulatory agencies have attempted to operate on a more flexible review basis than before. Although such disruptive approaches have partly reshaped drug development practices, issues and challenges remain before the completion of this paradigm shift in conventional drug development practices for the post-pandemic era. In this review, we have highlighted the role of a collaborative community of experts in order to figure out how disruptive technologies can be fully integrated into the current drug development practices and improve drug development efficiency for the post-pandemic era.

A hyper-specialization characterizes modern medicine with the consequence of classifying the various diseases of the body into unrelated categories. Such a broad diversification of medicine goes in the opposite direction of physics, which eagerly looks for unification. We argue that unification should also apply to medicine. In accordance with the second principle of thermodynamics, the cell must release its entropy either in the form of heat (catabolism) or biomass (anabolism). There is a decreased flow of entropy outside the body due to an age-related reduction in mitochondrial entropy yield resulting in increased release of entropy in the form of biomass. This shift toward anabolism has been known in oncology as Warburg-effect. The shift toward anabolism has been reported in most diseases. This quest for a single framework is reinforced by the fact that inflammation (also called the immune response) is involved in nearly every disease. This strongly suggests that despite their apparent disparity, there is an underlying unity in the diseases. This also offers guidelines for the repurposing of old drugs.

Under the partial influences of paradigm shift form category to dimension, the Diagnostic and Statistical Manual of Mental Disorder (DSM) was revised to the fifth edition (DSM-5); however, due to the lack of consistent biological makers and processes and the restricted availability of dimensional meta-structure, the revisions for the DSM-5 were based on a combination of categorical and dimensional approaches. Anxiety disorders were more clearly and consistently defined in the DSM-5 with the removal of obsessive compulsive, acute stress, and post-traumatic stress disorders. Differences between the childhood and adulthood categories of anxiety disorders were decreased, and overall, the symmetrical classification of anxiety subtypes was increased, since separation anxiety disorder and selective mutism were considered anxiety disorders, not neurodevelopmental disorders. Additionally, based on growing evidence, agoraphobia is distinct from panic disorder. Next, considering cultural syndromes including taijin kyofusho, khyal cap, trung gio attacks, and ataque de nervios, cultural influences are considered a significant factor for definitions and presentations of anxiety disorders. Controversies in the DSM-5 criteria for anxiety disorders are lowering the diagnostic thresholds of anxiety disorders and limiting the dichotomous view of anxiety and depression when defining generalized anxiety disorder. Further studies of alternative approaches to the restrictions of the DSM-5 criteria of anxiety disorders, including transdiagnostic specifiers and dimensional assessment tools, may be required.

BACKGROUND: Blockchain technology is leveraging its innovative potential in various sectors and its transformation of business-related processes has drawn much attention. Topics of research interest have focused on medical and health care applications, while research implications have generally concluded in system design, literature reviews, and case studies. However, a general overview and knowledge about the impact on the health care ecosystem is limited. OBJECTIVE: This paper explores a potential paradigm shift and ecosystem evolution in health care utilizing blockchain technology. METHODS: A literature review with a case study on a pioneering initiative was conducted. With a systematic life cycle analysis, this study sheds light on the evolutionary development of blockchain in health care scenarios and its interactive relationship among stakeholders. RESULTS: Four stages-birth, expansion, leadership, and self-renewal or death-in the life cycle of the business ecosystem were explored to elucidate the evolving trajectories of blockchain-based health care implementation. Focused impacts on the traditional health care industry are highlighted within each stage to further support the potential health care paradigm shift in the future. CONCLUSIONS: This paper enriches the existing body of literature in this field by illustrating the potential of blockchain in fulfilling stakeholders' needs and elucidating the phenomenon of coevolution within the health care ecosystem. Blockchain not only catalyzes the interactions among players but also facilitates the formation of the ecosystem life cycle. The collaborative network linked by blockchain may play a critical role on value creation, transfer, and sharing among the health care community. Future efforts may focus on empirical or case studies to validate the proposed evolution of the health care ecosystem.

Technological and policy solutions for transitioning to a fossil-free society exist, many countries could afford the transition, and rational arguments for rapid climate action abound. Yet effective action is still lacking. Dominant policy approaches have failed to generate action at anywhere near the rate, scale or depth needed to avoid potentially catastrophic futures. This is despite 30 years of climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC), and wide-ranging actions at national, transnational and sub-national levels. Practitioners and scholars are, thus, increasingly arguing that also the root causes of the problem must be addressed - the mindset (or paradigm) out of which the climate emergency has arisen. Against this background, we investigate decision-makers' views of the need for a different mindset and inner qualities that can support negotiating and activating climate action, along with factors that could enable such a mindset shift. Data were collected during participatory workshops run at the 25th UNFCCC Conference of the Parties (COP25) in 2019, and comprise surveys, as well as social media communication and semi-structured interviews with COP attendees. Our results underline vast agreement among participants regarding the need for a mindset shift that can support new ways of communication and collaboration, based on more relational modes of knowing, being and acting. They also suggest the emergence of such a mindset shift across sectors and contexts, but not yet at the collective and systems levels. Finally, they highlight the importance of transformative skills and the need for experimental, safe spaces. The latter are seen as a visible manifestation and enabler that can support agency for change through shared self-reflection, experience and practice. We present a transformative skills framework, and conclude with further research needs and policy recommendations.
