RESUMEN
BACKGROUND:: Legislative changes are resulting in assisted death as an option for people at the end of life. Although nurses' experiences and perspectives are underrepresented within broader ethical discourses about assisted death, there is a small but significant body of literature examining nurses' experiences of caring for people who request this option. AIM:: To synthesize what has been learned about nurses' experiences of caring for patients who request assisted death and to highlight what is morally at stake for nurses who undertake this type of care. DESIGN:: Qualitative meta-synthesis. METHODS:: Six databases were searched: CINAHL, Medline, EMBASE, Joanna Briggs Institute, PsycINFO, and Web of Science. The search was completed on 22 October 2014 and updated in February 2016. Of 879 articles identified from the database searches, 16 articles were deemed relevant based on inclusion criteria. Following quality appraisal, 14 studies were retained for analysis and synthesis. RESULTS:: The moral experience of the nurse is (1) defined by a profound sense of responsibility, (2) shaped by contextual forces that nurses navigate in everyday end-of-life care practice, and (3) sustained by intra-team moral and emotional support. DISCUSSION:: The findings of this synthesis support the view that nurses are moral agents who are deeply invested in the moral integrity of end-of-life care involving assisted death. The findings further demonstrate that to fully appreciate the ethics of assisted death from a nursing standpoint, it is necessary to understand the broader constraints on nurses' moral agency that operate in everyday end-of-life care. ETHICAL CONSIDERATIONS:: Research ethics board approval was not required for this synthesis of previously published literature. CONCLUSION:: In order to understand how to enact ethical practice in the area of assisted death, the moral experiences of nurses should be investigated and foregrounded.

Innate immune responses provoke the accumulation of leukocytes at sites of inflammation. In addition to monocytes and granulocytes, B cells also participate in antimicrobial innate immune responses; however, the mechanisms for accumulation of B cells to sites of inflammation are not well understood. To study B cell accumulation following systemic inflammation, we used a model synthetic ligand that stimulates a specific pattern recognition molecule, nucleotide-binding oligomerization domain-containing protein 1 (Nod1). Upon exposure to Nod1 agonists, both B cells and neutrophils rapidly accumulate within the spleen, and dendritic cells migrate into the periarterial lymphoid sheath. Nod1 stimulation led to a marked increase in several chemokines within the spleen, including CXCL13, CCL2, and CCL20. Whereas the lymphotoxin pathway was critical for the induction of the B cell chemoattractant CXCL13 in response to Nod1 agonists, B cell accumulation within the spleen following Nod1-induced systemic inflammation was independent of the lymphotoxin pathway. In contrast, a CCR6/CCL20 chemokine loop instructed rapid increase of B cells in the spleen in response to systemic administration of Nod1 agonists in a TNF-α-dependent manner. Moreover, CCR6 was required to regulate Nod1-mediated B cell responses. These results reveal a novel mechanism of B cells during inflammation and shed light on how B cells participate in innate immune responses to microbial stimulation.
