Experiences of Medical Interpreters During Palliative Care Encounters With Limited English Proficiency Patients: A Qualitative Study.

Background: There are many challenges in communication and cultural barriers for patients with limited English proficiency (LEP) who suffer from serious illnesses. Palliative care utilization among this population remains limited and the experiences of medical interpreters during palliative care encounters remain understudied. Methods: We conducted semistructured video interviews with interpreters working at an academic medical center. Interview questions explored interpreters' observations and experiences during palliative care encounters with LEP patients. We performed thematic analysis of the interview contents. Results: Our study included 20 interpreters who interpret in 9 languages with a mean experience of 16.3 years. We identified four themes from the interviews that shed light on the challenges of incorporating palliative care into the care of patients with LEP: (1) lack of a verbatim interpretation for the term "palliative care," (2) poor patient understanding of their treatment goals, (3) suboptimal timing of palliative care involvement, and (4) fears and misconceptions related to palliative care. Owing to challenges in word choice, the timing of palliative care involvement, and poor understanding of palliative care, interpreters observed that many patients with LEP declined palliative care involvement in their treatment plan. Conclusions: In this study, we identified several actionable barriers interpreters noted to incorporating palliative care into care of patients with LEP. Interventions directed toward providing LEP patients with standardized culturally appropriate information on palliative care are needed.

Forgotten in the crowd: A qualitative study of medical interpreters' role in medical teams.

BACKGROUND: Patients with limited English proficiency (LEP) experience worse outcomes compared with native English speakers. Communication errors are partly responsible for the disparities among this population. Medical interpreters improve communication and often assume multiple roles during clinical encounters. We sought to explore the perspectives of medical interpreters regarding their role within medical teams and ways to improve communication. METHODS: We conducted a qualitative study using semistructured interviews with inpatient and outpatient medical interpreters at an academic medical center between March and August 2021. Interview questions explored interpreters' perceptions of their roles within the medical team and best practices to improve communication during encounters. Interview transcripts were analyzed using thematic analysis. RESULTS: Our sample consisted of 20 interpreters with a mean age of 48 years (SD: 14.3) and a mean experience of 16.3 years (SD: 10.6). Two main themes emerged from interviews: (1) the full spectrum of medical interpreters' role and (2) factors acting as barriers and facilitators of interpretation. Interpreters described their role as language interpreters, cultural mediators, and patient advocates. They also identified several factors that may enhance encounters, such as utilizing the teach-back method with patients and debriefing with interpreters. CONCLUSIONS: Interpreters view their role as extending beyond interpretation to include cultural mediation and patient advocacy. Addressing commonly encountered challenges and adopting some of the proposed solutions highlighted in this study may facilitate improved communication with LEP patients receiving care in healthcare systems.

Small RNA-seq during acute maximal exercise reveal RNAs involved in vascular inflammation and cardiometabolic health: brief report.

Exercise improves cardiometabolic and vascular function, although the mechanisms remain unclear. Our objective was to demonstrate the diversity of circulating extracellular RNA (ex-RNA) release during acute exercise in humans and its relevance to exercise-mediated benefits on vascular inflammation. We performed plasma small RNA sequencing in 26 individuals undergoing symptom-limited maximal treadmill exercise, with replication of our top candidate miRNA in a separate cohort of 59 individuals undergoing bicycle ergometry. We found changes in miRNAs and other ex-RNAs with exercise (e.g., Y RNAs and tRNAs) implicated in cardiovascular disease. In two independent cohorts of acute maximal exercise, we identified miR-181b-5p as a key ex-RNA increased in plasma after exercise, with validation in a separate cohort. In a mouse model of acute exercise, we found significant increases in miR-181b-5p expression in skeletal muscle after acute exercise in young (but not older) mice. Previous work revealed a strong role for miR-181b-5p in vascular inflammation in obesity, insulin resistance, sepsis, and cardiovascular disease. We conclude that circulating ex-RNAs were altered in plasma after acute exercise target pathways involved in inflammation, including miR-181b-5p. Further investigation into the role of known (e.g., miRNA) and novel (e.g., Y RNAs) RNAs is warranted to uncover new mechanisms of vascular inflammation on exercise-mediated benefits on health.NEW & NOTEWORTHY How exercise provides benefits to cardiometabolic health remains unclear. We performed RNA sequencing in plasma during exercise to identify the landscape of small noncoding circulating transcriptional changes. Our results suggest a link between inflammation and exercise, providing rich data on circulating noncoding RNAs for future studies by the scientific community.

A Novel Transgenic Mouse Model of Cardiac Hypertrophy and Atrial Fibrillation.

Cardiac hypertrophy is a major risk factor for the development of atrial fibrillation (AF). However, there are few animal models of AF associated with cardiac hypertrophy. In this study, we describe the in vivo electrophysiological characteristics and histopathology of a mouse model of cardiac hypertrophy that develops AF. Myostatin is a well-known negative regulator of skeletal muscle growth that was recently found to additionally regulate cardiac muscle growth. Using cardiac-specific expression of the inhibitory myostatin pro-peptide, we generated transgenic (TG) mice with dominant-negative regulation of MSTN (DN-MSTN). One line (DN-MSTN TG13) displayed ventricular hypertrophy, as well as spontaneous AF on the surface electrocardiogram (ECG), and was further evaluated. DN-MSTN TG13 had normal systolic function, but displayed atrial enlargement on cardiac MRI, as well as atrial fibrosis histologically. Baseline ECG revealed an increased P wave duration and QRS interval compared with wild-type littermate (WT) mice. Seven of 19 DN-MSTN TG13 mice had spontaneous or inducible AF, while none of the WT mice had atrial arrhythmias (p<0.05). Connexin40 (Cx40) was decreased in DN-MSTN TG13 mice, even in the absence of AF or significant atrial fibrosis, raising the possibility that MSTN signaling may play a role in Cx40 down-regulation and the development of AF in this mouse model. In conclusion, DN-MSTN TG13 mice represent a novel model of AF, in which molecular changes including an initial loss of Cx40 are noted prior to fibrosis and the development of atrial arrhythmias.
