RESUMEN
OBJECTIVES: To assess quality of life (QOL) outcomes after canal wall up (CWU) and canal wall down (CWD) tympanomastoidectomy in the pediatric population. METHODS: A retrospective review tabulated pediatric patients undergoing CWU and CWD tympanomastoidectomy for cholesteatoma by 2 senior surgeons at a single tertiary academic referral center between March 2017 and March 2023. Chronic Ear Survey (CES) and cosmetic survey outcomes were collected post-operatively. RESULTS: A total of 77 ears in 75 patients were identified, with 35 undergoing CWU and 42 undergoing CWD as the most recent (index) otologic surgery. Seventeen patients (23%) participated in the survey. Of this cohort, the mean age was 14.6 years, 12 (71%) were male, and 10 (59%) had CWD as the most recent otologic surgery. The mean time from index surgery to survey completion was 3.4 years (range, 0.1-6.7 years). Regarding QOL outcomes, there were no statistically significant differences in total CES score, CES subscores, and cosmetic survey scores between groups when categorizing by gender or index surgery. Total CES, symptom subscale, medical resource subscale, and cosmetic survey scores showed a tendency to decrease with an increasing number of surgeries (R = -.18, -.28, -.53, and -.56, respectively). Pediatric total CES scores appeared comparable to those reported in the published adult literature. CONCLUSIONS: It does not appear that there are worse QOL outcomes for pediatric patients who undergo CWD tympanomastoidectomy compared to those who undergo CWU tympanomastoidectomy. There appears to be no difference in QOL outcomes between pediatric and adult patients undergoing tympanomastoidectomy.
RESUMEN
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.
RESUMEN
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.
