Racial Equity, Diversity and Inclusion in Bioethics: Recommendations from the Association of Bioethics Program Directors Presidential Task Force.

Recent calls to address racism in bioethics reflect a sense of urgency to mitigate the lethal effects of a lack of action. While the field was catalyzed largely in response to pivotal events deeply rooted in racism and other structures of oppression embedded in research and health care, it has failed to center racial justice in its scholarship, pedagogy, advocacy, and practice, and neglected to integrate anti-racism as a central consideration. Academic bioethics programs play a key role in determining the field's norms and practices, including methodologies, funding priorities, and professional networks that bear on equity, inclusion, and epistemic justice.

When Artists Go to Work: On the Ethics of Engaging the Arts in Public Health.

Collaboration between the arts and health sectors is gaining momentum. Artists are contributing significantly to public health efforts such as vaccine confidence campaigns. Artists and the arts are well positioned to contribute to the social conditions needed to build trust in the health sector.

Resolving responsibility gaps for lethal autonomous weapon systems.

This paper offers a novel understanding of collective responsibility for AI outcomes that can help resolve the "problem of many hands" and "responsibility gaps" when it comes to AI failure, especially in the context of lethal autonomous weapon systems.

Methacrylated Bovine Serum Albumin and Tannic Acid Composite Materials for Three-Dimensional Printing Tough and Mechanically Functional Parts.

Nature uses proteins as building blocks to create three-dimensional (3D) structural components (like spiderwebs and tissue) that are recycled within a closed loop. Furthermore, it is difficult to replicate the mechanical properties of these 3D architectures within synthetic systems. In the absence of biological machinery, protein-based materials can be difficult to process and can have a limited range of mechanical properties.

Speaking Volumes: The Encyclopedia of Bioethics and Racism.

This essay takes as its starting point the claim that addressing anti-Black racism is essential to the work of bioethics in the United States. The essay examines whether and how racism has been addressed in the field's central reference work, the Encyclopedia of Bioethics, throughout its four editions-in 1978, 1995, 2004, and 2014. With consideration of each edition's stated purpose and editorial framing, we find that the subject of racism is obscured by the Encyclopedia's inattention to African American approaches to bioethics, to racism as a bioethics issue, and specifically, to racism as a matter of justice.

Addressing Anti-Black Racism in Bioethics: Responding to the Call.

As a field concerned with ethical issues in health and health care, particularly how structures, policies, and practices unfairly advantage some and disadvantage others, bioethics has a moral obligation to address the long-standing challenges that racism has posed to the overall health and well-being of Black, Indigenous, and Latinx people and other people of color. Arguably, the premature death and disease disproportionately affecting Black Americans and the well-documented association of such death and illness with racism are issues that have not gained due attention in bioethics. This multiauthored report highlights the intergenerational work of mostly Black scholars and aims to create an agenda for bioethics that addresses anti-Black racism and the ways in which this form of racism threatens the actualization of justice in health and health care, not only for Black people and other minoritized groups but also for all people.

Respect for Communities in Health Justice.

Health justice seeks, both conceptually and in practice, to strengthen community engagement and empowerment as an integral means of addressing health disparities. In this essay, we explore the nature of communities and their roles in health care/public health. We propose that an ethical  is a requisite part of health justice.

3D-Printed Bioplastics with Shape-Memory Behavior Based on Native Bovine Serum Albumin.

Bio-based plastics that can supplant petroleum-derived materials are necessary to meet the future demands of sustainability in the life cycle of plastic materials. While there are significant efforts to develop protein-based plastic materials for commercial use, their application is limited by poor processability and limitations in mechanical performance. Here, we present a bovine serum albumin (BSA)-based resin for stereolithographic apparatus (SLA) 3D printing that affords bioplastic objects with shape-memory behavior.

Additive Manufacturing of Bovine Serum Albumin-Based Hydrogels and Bioplastics.

Biosourced and biodegradable polymers for additive manufacturing could enable the rapid fabrication of parts for a broad spectrum of applications ranging from healthcare to aerospace. However, a limited number of these materials are suitable for vat photopolymerization processes. Herein, we report a two-step additive manufacturing process to fabricate robust protein-based constructs using a commercially available laser-based stereolithography printer.

3D printed coaxial nozzles for the extrusion of hydrogel tubes toward modeling vascular endothelium.

Engineered tubular constructs made from soft biomaterials are employed in a myriad of applications in biomedical science. Potential uses of these constructs range from vascular grafts to conduits for enabling perfusion of engineered tissues and organs. The fabrication of standalone tubes or complex perfusable constructs from biofunctional materials, including hydrogels, via rapid and readily accessible routes is desirable.

Training Community Clergy in Serious Illness: Balancing Faith and Medicine.

Community-based clergy are highly engaged in helping seriously ill patients address spiritual concerns at the end of life (EOL). While they desire EOL training, no data exist in guiding how to conceptualize a clergy-training program. The objective of this study was used to identify best practices in an EOL training program for community clergy.

Seeking and Accepting: U.S. Clergy Theological and Moral Perspectives Informing Decision Making at the End of Life.

Background: People with serious illness frequently rely on religion/spirituality to cope with their diagnosis, with potentially positive and negative consequences. Clergy are uniquely positioned to help patients consider medical decisions at or near the end of life within a religious/spiritual framework.

Objective: We aimed to examine clergy knowledge of end-of-life (EOL) care and beliefs about the role of faith in EOL decision making for patients with serious illness.

U.S. Clergy Religious Values and Relationships to End-of-Life Discussions and Care.

Context: Although clergy interact with approximately half of U.S. patients facing end-of-life medical decisions, little is known about clergy-congregant interactions or clergy influence on end-of-life decisions.

How Community Clergy Provide Spiritual Care: Toward a Conceptual Framework for Clergy End-of-Life Education.

Context: Community-based clergy are highly engaged in helping terminally ill patients address spiritual concerns at the end of life (EOL). Despite playing a central role in EOL care, clergy report feeling ill-equipped to spiritually support patients in this context. Significant gaps exist in understanding how clergy beliefs and practices influence EOL care.

Clergy Views on a Good Versus a Poor Death: Ministry to the Terminally Ill.

Background: Clergy are often important sources of guidance for patients and family members making medical decisions at the end-of-life (EOL). Previous research revealed spiritual support by religious communities led to more aggressive care at the EOL, particularly among minority patients. Understanding this phenomenon is important to help address disparities in EOL care.

Whose role? Oncology practitioners' perceptions of their role in providing spiritual care to advanced cancer patients.

Purpose: The purpose of this study is to determine how oncology nurses and physicians view their role in providing spiritual care (SC), factors influencing this perception, and how this belief affects SC provision.

Methods: This is a survey-based, multisite study conducted from October 2008 to January 2009. All oncology physicians and nurses caring for advanced cancer patients at four Boston, MA cancer centers were invited to participate; 339 participated (response rate = 63 %).

Crystal structures of the Toll/Interleukin-1 receptor (TIR) domains from the Brucella protein TcpB and host adaptor TIRAP reveal mechanisms of molecular mimicry.

The Toll/IL-1 receptor (TIR) domains are crucial innate immune signaling modules. Microbial TIR domain-containing proteins inhibit Toll-like receptor (TLR) signaling through molecular mimicry. The TIR domain-containing protein TcpB from Brucella inhibits TLR signaling through interaction with host adaptor proteins TIRAP/Mal and MyD88.

Analysis of A2a receptor-deficient mice reveals no significant compensatory increases in the expression of A2b, A1, and A3 adenosine receptors in lymphoid organs.

Although recent genetic and pharmacologic in vivo studies of acute inflammation models in mice demonstrated that the cyclic AMP-elevating A2a receptor plays a non-redundant role in protection from excessive acute inflammatory tissue damage and in the down-regulation of proinflammatory cytokine production, it remained to be established whether genetic deficiency of the A2a receptor is accompanied by a compensatory up-regulation of the cAMP-elevating A2b receptor and/or other adenosine receptors. Here, we show that most of the cAMP response to adenosine is abolished in lymphoid tissues of A2a receptor-deficient mice, although some response remains in splenocytes. No significant changes were observed in A2b, A1, and A3 mRNA levels in the thymus or lymph nodes of A2a receptor-deficient mice, but small increases in mRNA expression of these receptors were detected in the spleen.
