Designing and delivering a poetry workshop for clinician well-being during the COVID-19 pandemic: A case study.
Facilitated poetry writing workshops are used in healthcare settings as a therapeutic approach to address stressful factors that negatively influence clinician well-being. However, owing to the novelty of this intervention and a tendency to combine poetry with other types of narrative-based techniques, proponents of poetic medicine are calling for harmonization across programs in the US. This would facilitate the study of poetry in medicine and the multiple facets of well-being it is said to promote. To address these points, we partnered with a well-established poetry center to develop and study a facilitated poetry writing workshop program for palliative care and emergency medicine clinicians during the COVID-19 pandemic. ⋯ Healthcare systems seeking to incorporate poetry into their wellness programming may build upon our findings to create flexible workshops suited to their clinician audience and program intent.

Cardiac AL and ATTR are potentially fatal cardiomyopathies. Current therapies do not address mechanisms of tissue dysfunction because these remain unknown. Our prior work focused on the amyloid plaque proteome, which may not capture tissue-wide proteomic alterations. ⋯ This study identifies known processes dysregulated in heart failure with preserved ejection fraction as well as novel pathways responsible for tissue damage. Our results support an immune-mediated mechanism of tissue toxicity in cardiac amyloidosis, especially among patients with worse outcomes.

Danger signals modulate pain perception. Both amplification and attenuation of perceived pain are observed in healthy subjects exposed to danger signals, such as transient threats of an imminent electrical shock. However, exposure to danger signals in real life typically is not transient but constant over minutes to hours. Here, this was experimentally achieved by administering hypercapnic air (7.5% CO2). The primary objective was to investigate whether perceived heat pain would be differentially modulated during this intervention compared to regular air administration. The secondary objective assessed the potential differences of such a modulation with respect to heat intensity level. ⋯ It was shown that hypercapnia leads to reduced perception of noxious heat stimuli. If confirmed by neural data in future studies this could help to better understand the interaction of pain perception and continuous physiological danger signals in clinical pain conditions, potentially allowing for improved treatment of affected individuals.

Treating bone cancer pain (BCP) continues to be a clinical challenge, and the underlying mechanisms of BCP remain elusive. This study reports that Wnt5a/Ryk signaling in the dorsal root ganglion neurons is critical to the development of BCP. Tibia bone cavity tumor cell implantation produces spontaneous and evoked behaviorally expressed pain as well as ectopic sprouting and activity of Wnt5a/Ryk signaling in the neural soma and peripheral terminals and the tumor-affected bone tissues. ⋯ Blocking Ryk receptor activation suppresses Wnt5a-induced mechanical allodynia and thermal hyperalgesia. Wnt5a facilitation of transient receptors potential vanilloid type-1 sensitization is blocked by inhibiting c-Jun N-terminal kinase activation. These findings indicate a critical peripheral mechanism of Wnt5a/Ryk signaling underlying the pathogenesis of BCP and suggest that targeting Wnt5a/Ryk in the primary sensory neurons and the tumor-invasive area may be an effective approach for the prevention and treatment of BCP.
