Abstract Natural killer (NK) cells represent key effectors of antitumor immunity, yet emerging evidence highlights populations with distinct roles in cancer. Despite such expanded diversity within the NK cell repertoire, we lack an understanding of how this heterogeneity affects immune responses and downstream clinical outcomes. Using single-cell RNA sequencing, we systematically profiled NK cells across cancer and uncovered a dichotomous phenotypic and functional landscape of tumor-infiltrating NK cells shaped by opposing intrinsic signaling programs that drive the expression of IFNG or TGFB1. These divergent programs are associated with distinct transcription factor circuits that integrate cues within the tumor microenvironment and skew NK cells toward proinflammatory or suppressive functions. We found that the capacity for NK cells to engage in either functional direction is intrinsically linked to their phenotypic identity. Canonical NK cells recruited from circulation predominantly directed suppressive TGFB1 signals toward effector CD8+ T cells in tumors. Of note, these subsets exhibited higher TGFB1 expression than intratumoral myeloid cells across tumor types. In contrast, a tissue-resident (TR) adaptive subset exhibited exclusively proinflammatory IFNG-driven profiles and was associated with prolonged survival in both primary and metastatic tumor settings. Moreover, these TR adaptive NK cells, but not other subsets, were linked to response to immune checkpoint blockade. Collectively, our study reveals a previously unrecognized regulatory axis in NK cells that shapes NK cell diversity and augments broader antitumor immune responses.

A strong organizational culture begins with leadership who create systems and structures to support safety and well-being of staff. The purpose of this article is to provide direction for nursing leaders on resources and actionable items to support staff who have been involved in challenging encounters with patient behavior. Staff needs are impacted not only by the situation but also by available on-the-job support and leadership respect for staff’s individual judgment. Postsituation support from both leaders and peers offer a protective effect against negative outcomes from adverse experiences. Ultimately, staff preferences for specific resources are individual and best determined through private conversation with their leadership. Given the unique nature of each situation, taking into account patient intentions and staff perceptions, it is important to offer flexible and actionable measures for staff managing challenging patient behaviors.

Background Cardiovascular disease is linked to mental health conditions. Patients with cardiovascular disease and comorbid psychiatric illnesses such as major depressive disorder or generalized anxiety disorder often experience greater physical limitations and decreased overall health. Objective To determine if proactive psychiatric interventions improve staff satisfaction and patient outcomes, such as reducing length of stay and decreasing the 30-day readmission rate, for patients hospitalized on cardiac units with psychiatric comorbidities. Methods The implementation of a proactive psychiatric consultation-liaison service, which included proactive screening of psychiatric needs among patients hospitalized on cardiac units, targeted support for cardiovascular staff, and supportive interactions for patients. Results Comparison between preintervention and postintervention periods indicated a 21% reduction in the 30-day readmission rate for patients hospitalized on cardiac inpatient units with psychiatric comorbidities without adversely affecting hospital length of stay. Staff satisfaction significantly increased with the availability of psychiatric resources. Conclusion The implementation of a multi-disciplinary proactive psychiatric consultation-liaison service on inpatient cardiac units was associated with an increase in cardiovascular staff satisfaction with psychiatric services and a decrease in the 30-day readmission rate of patients with psychiatric comorbidities who were hospitalized for cardiovascular services without significantly affecting length of stay.
