The what matters most survey: A measurement evaluation of a self-reported patient values elicitation tool among cancer survivors.

OBJECTIVES: Patients with multiple chronic conditions, especially cancer survivors, face challenges in medical decision making. Previous research demonstrates how patient values can guide medical decisions, however facilitating patient values elicitation remains a challenge. This study aims to evaluate the psychometric properties of and refine the What Matters Most (WMM) Survey, a self-reported values elicitation tool, in a cohort of older veteran cancer survivors. METHODS: An observational cohort study was conducted to evaluate the psychometric properties of the WMM Survey in older, multimorbid cancer survivors. 262 patients were administered the assessment at two timepoints, between 14 and 30 days apart. RESULTS: Exploratory factor analyses revealed four factors for assessing healthcare values among older adults with good internal consistency for all factors: Functioning (Cronbach's alpha coefficient, α = 0.88), Enjoying Life (α = 0.79), Connecting (α = 0.84), and Managing Health (α = 0.88). Demographic and clinical characteristics were not uniformly associated with specific healthcare values. CONCLUSIONS: Future studies are required to refine the proposed assessment and to evaluate its application in a general patient population. PRACTICE IMPLICATIONS: The WMM Survey is an innovative resource in health values elicitation, allowing for facilitation of patient-clinician communication for whole-person medical approaches and measurement of health values for research.

Elevated Hoxb5b Expands Vagal Neural Crest Pool and Blocks Enteric Neuronal Development in Zebrafish.

Neural crest cells (NCCs) are a migratory, transient, and multipotent stem cell population essential to vertebrate embryonic development, contributing to numerous cell lineages in the adult organism. While great strides have been made in elucidating molecular and cellular events that drive NCC specification, comprehensive knowledge of the genetic factors that orchestrate NCC developmental programs is still far from complete. We discovered that elevated Hoxb5b levels promoted an expansion of zebrafish NCCs, which persisted throughout multiple stages of development. Correspondingly, elevated Hoxb5b also specifically expanded expression domains of the vagal NCC markers foxd3 and phox2bb. Increases in NCCs were most apparent after pulsed ectopic Hoxb5b expression at early developmental stages, rather than later during differentiation stages, as determined using a novel transgenic zebrafish line. The increase in vagal NCCs early in development led to supernumerary Phox2b+ enteric neural progenitors, while leaving many other NCC-derived tissues without an overt phenotype. Surprisingly, these NCC-derived enteric progenitors failed to expand properly into sufficient quantities of enterically fated neurons and stalled in the gut tissue. These results suggest that while Hoxb5b participates in vagal NCC development as a driver of progenitor expansion, the supernumerary, ectopically localized NCC fail to initiate expansion programs in timely fashion in the gut. All together, these data point to a model in which Hoxb5b regulates NCCs both in a tissue specific and temporally restricted manner.
