RESUMO

PURPOSE: Anterior urethral stricture disease (aUSD) is a complex, heterogeneous condition that is idiopathic in origin for most men. This gap in knowledge rarely affects the current management strategy for aUSD, as urethroplasty does not generally consider etiology. However, as we transition towards personalized, minimally invasive treatments for aUSD and begin to consider aUSD prevention strategies, disease pathophysiology will become increasingly important. The purpose of this study was to perform a deep phenotype of men undergoing anterior urethroplasty for aUSD. We hypothesized that unique biologic signatures and potential targets for intervention would emerge based on stricture presence/absence, stricture etiology, and the presence/absence of stricture inflammation. MATERIALS AND METHODS: Men with aUSD undergoing urethroplasty were recruited from one of 5 participating centers. Enrollees provided urethral stricture tissue and blood/serum on the day of surgery and completed patient-reported outcome measure questionnaires both pre- and postoperatively. The initial study had 3 aims: (1) to determine pediatric and adult subacute and repeated perineal trauma (SRPT) exposures using a study-specific SRPT questionnaire, (2) to determine the degree of inflammation and fibrosis in aUSD and peri-aUSD (normal urethra) tissue, and (3) to determine levels of systemic inflammatory and fibrotic cytokines. Two controls groups provided serum (normal vasectomy patients) and urethral tissue (autopsy patients). Cohorts were based on the presence/absence of stricture, by presumed stricture etiology (idiopathic, traumatic/iatrogenic, lichen sclerosus [LS]), and by the presence/absence of stricture inflammation. RESULTS: Of 138 enrolled men (120 tissue/serum; 18 stricture tissue only), 78 had idiopathic strictures, 33 had trauma-related strictures, and 27 had LS-related strictures. BMI, stricture length, and stricture location significantly differed between cohorts (P < .001 for each). The highest BMIs and the longest strictures were observed in the LS cohort. SRPT exposures did not significantly differ between etiology cohorts, with > 60% of each reporting low/mild risk. Stricture inflammation significantly differed between cohorts, with mild to severe inflammation present in 27% of trauma-related strictures, 54% of idiopathic strictures, and 48% of LS strictures (P = .036). Stricture fibrosis did not significantly differ between cohorts (P = .7). Three serum cytokines were significantly higher in patients with strictures compared to stricture-free controls: interleukin-9 (IL-9; P = .001), platelet-derived growth factor-BB (P = .004), and CCL5 (P = .01). No differences were observed in the levels of these cytokines based on stricture etiology. However, IL-9 levels were significantly higher in patients with inflamed strictures than in patients with strictures lacking inflammation (P = .019). Degree of stricture inflammation positively correlated with serum levels of IL-9 (Spearman's rho 0.224, P = .014). CONCLUSIONS: The most common aUSD etiology is idiopathic. Though convention has implicated SRPT as causative for idiopathic strictures, here we found that patients with idiopathic strictures had low SRPT rates that were similar to rates in patients with a known stricture etiology. Stricture and stricture-adjacent inflammation in idiopathic stricture were similar to LS strictures, suggesting shared pathophysiologic mechanisms. IL-9, platelet-derived growth factor-BB, and CCL5, which were elevated in patients with strictures, have been implicated in fibrotic conditions elsewhere in the body. Further work will be required to determine if this shared biologic signature represents a potential mechanism for an aUSD predisposition.

RESUMO

Sustaining a burn injury often results in a life-long recovery process. Survivors are impacted by changes in their mobility, appearance, and ability to carry out activities of daily living. In this study, we examined survivors' accounts of their treatment and recovery in order to identify specific factors that have had significant impacts on their well-being. With this knowledge, we may be better equipped to optimize the care of burn patients. We conducted inductive, thematic analysis on transcripts of in-depth, semistructured interviews with 11 burn survivors. Participants were purposefully selected for variability in age, gender, injury size and mechanism, participation in peer support, and rurality. Survivors reported varied perceptions of care quality and provider relationships. Ongoing issues with skin and mobility continued to impact their activities of daily living. Many survivors reported that they did not have a clear understanding or realistic expectations of the recovery process. Wound care was often described as overwhelming and provoked fear for many. Even years later, trauma from burn injury can continue to evolve, creating fears and impediments to daily living for survivors. To help patients understand the realistic course of recovery, providers should focus on communicating the nature of injury and anticipated recovery, developing protocols to better identify survivors facing barriers to care, and referring survivors for further support.

RESUMO

PURPOSE: To measure the impact of tying adoption of evidence-based worksite health promotion (WHP) interventions to annual organizational strategic objectives, as measured by the Centers for Disease Control and Prevention (CDC) Worksite Health ScoreCard (ScoreCard). DESIGN: A prospective cohort study following Johns Hopkins Medicine (JHM) affiliates against industry-specific and large employer benchmarks from 2016-2020. SETTINGS: JHM, the largest private employer in Maryland with facilities in Florida and the District of Columbia. SUBJECTS: Twelve JHM affiliates representing over 40,000 employees. INTERVENTION: A strategic objective was established annually based on the ScoreCard and organizational priorities. MEASURES: JHM affiliates measured their WHP efforts annually using the ScoreCard. CDC industry-specific and large employer benchmarks were collected for comparison. ANALYSIS: ScoreCard data was assessed annually to measure deviations from CDC benchmarks, determine whether strategic objectives were met, and inform additional annual objectives. RESULTS: JHM demonstrated improvement from 8.9 percentage points above industry-specific and 3.4 percentage points below large employer benchmarks in 2016, to 26.4 percentage points above industry-specific and 21.8 percentage points above large employer benchmarks in 2020. CONCLUSION: Large employers face unique challenges in implementing WHP programs. Our study suggests embedding health promotion in annual strategic objectives may alleviate these challenges by prioritizing the goal and ensuring adequate resources to be successful. There are however, some limitations on using benchmarking data for comparison.
