Rosacea and Gastrointestinal Diseases: A Case-Control Study in the All of Us Database.

INTRODUCTION: Recent reports have suggested a link between rosacea and several gastrointestinal diseases, although the evidence has largely been limited to European and Asian populations. This study seeks to confirm and expand upon the connection between rosacea and gastrointestinal conditions using the diverse All of Us database. METHODS: We identified 8,319 rosacea patients and selected 4:1 controls matched (n = 33,276) based on age, race, gender, smoking status, insurance status, annual income, education, and alcohol use. Conditional logistic regression was then performed on the matched cohort to assess the relationship between rosacea and Crohn's disease (CD), microscopic colitis, ulcerative colitis (UC), celiac disease (CED), irritable bowel syndrome (IBS), Helicobacter-associated disease, and gastroesophageal reflux disease (GERD). RESULTS: On logistic regression, rosacea patients were significantly more likely than matched controls to be diagnosed with IBS (odds ratio [OR]: 2.35, 95% confidence interval [CI]: 2.18-2.53, p < 0.001), CD (OR: 1.82, 95% CI: 1.53-2.15, p < 0.001), UC (OR: 1.70, 95% CI: 1.44-2.02, p < 0.001), CED (OR: 1.93, 95% CI: 1.59-2.34, p < 0.001), Helicobacter-associated disease (OR: 1.79, 95% CI: 1.50-2.14, p < 0.001), and GERD (OR: 2.07, 95% CI: 1.97-2.18, p < 0.001). However, there was no statistically significant association between rosacea and microscopic colitis (OR: 1.47, 95% CI: 0.91-2.37, p = 0.12). CONCLUSION: This study highlights the presence of notable gastrointestinal comorbidities among individuals with rosacea in a diverse cohort. Consequently, more targeted monitoring of gastrointestinal diseases in rosacea patients may be warranted, as well as potential further investigation into the gut-skin axis in terms of rosacea pathophysiology.

Time to second biochemical recurrence as a prognostic indicator in postprostatectomy patients who undergo salvage radiation therapy: An RTOG 9601 based post hoc analysis.

INTRODUCTION AND OBJECTIVE: The prognostic significance of a "second" biochemical recurrence (sBCR) after salvage radiation therapy (sRT) with/without hormonal therapy following primary radical prostatectomy in men with prostate cancer has not been examined. We hypothesized that a shorter time to sBCR will be associated with worse cancer control outcomes. METHODS: The RTOG 9601 study included 760 patients with tumor stage pT2/T3, pN0, who had either persistently elevated prostate-specific antigen (PSA) postradical prostatectomy or developed subsequent biochemical recurrence with PSA levels between 0.2 and 4.0 ng/ml. All patients received sRT (with or without 2 years of Bicalutamide) from 1998 to 2015. For our study, we focused on 421 patients who had sBCR after sRT-which was defined as a PSA increase of at least 0.3 ng/ml over the first nadir. Patients were divided into two categories: early sBCR (n = 210) and late sBCR (n = 211) using median time to sBCR (3.51 years). All patients who experienced sBCR received salvage hormonal therapy. Competing-risk analysis was used to examine the impact of early versus late sBCR on prostate cancer specific mortality (CSM), after accounting for available covariates. RESULTS: The majority of patients were age 60 years or older (75.8%), had pT3 disease (74.8%), and Gleason score 7 (75.2%). Overall, 13.8% had persistent PSA initially after surgery. At 10 years, starting at the time of sBCR, CSM rate was 31.3% in the early sBCR group versus 20.0% in the late sBCR group. In competing-risk analysis, time to sBCR was an independent predictor of CSM, where patients with early sBCR had 1.7-fold higher CSM risk (p = 0.026) than their counterparts with late sBCR. CONCLUSIONS: Time to sBCR after sRT (with or without concomitant Bicalutamide) is a significant predictor of CSM following initial radical prostatectomy. This information can be used to guide subsequent treatments, and to counsel patients.

Use of a topical Janus kinase inhibitor in immune checkpoint inhibitor-induced eczematous reaction: a case report.

In this report, we describe the case of a 28-year-old female with bilateral breast cancer in the setting of a BRCA1 mutation, who presented to dermatology with an eczematous reaction, ultimately diagnosed as a cutaneous immune-related adverse event (cirAE) secondary to an immune checkpoint inhibitor (ICI), pembrolizumab. Our case report highlights a novel therapeutic option for an eczematous cirAE: the topical JAK 1/2 inhibitor, ruxolitinib. CirAEs can occur in up to 55% of patients on ICIs, a class of medications seeing rapidly increasing use in cancer therapy, and prior research has demonstrated that ICI-induced dermatitis may involve different pathways than traditionally observed in their spontaneous counterparts. Specifically, marked Th1 skewing is noted in ICI-induced dermatitis, as opposed to a predominant Th2 response which typically characterizes spontaneous atopic dermatitis. To our knowledge, this is the first case report in the literature discussing use of a topical JAK inhibitor, ruxolitinib, in the treatment of topical steroid-refractory cirAEs. Furthermore, as topical JAK inhibitors are thought to not carry the risks of systemic JAK inhibitors, including malignancy, ruxolitinib cream is a promising therapeutic option for this challenging patient population.

Top 100 Urology Influencers on Twitter: Is Social Media Influence Associated with Academic Impact?

BACKGROUND: Social media use in medicine has exploded, with uptake by most physicians and patients. There is a risk of dissemination of inaccurate information about urological conditions on social media. Physicians, as key opinion leaders, must play a role in sharing evidence-based information through social media. OBJECTIVE: To identify and describe the top 100 urology influencers on the Twitter social media platform and to correlate Twitter influence with academic impact in urology. DESIGN, SETTING, AND PARTICIPANTS: Twitter influence scores for the search topic "urology" were collected in April 2022 using published methodology. The top 100 personal accounts with the highest computed scores were linked to individuals' names, all-time h index, geographic location, specialty, attributed sex, and board certification status in this cross-sectional study. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We examined the correlation between influence rank and h index. RESULTS AND LIMITATIONS: Of the top 100 Twitter influencers on the topic of urology, the majority are from the USA (64%), male (85%), and practicing urologists (91%). Some 93% of US urology influencers are board-certified. Only 22 of the 50 US states are represented. The second most frequent country is the UK, with ten urology influencers. The median all-time h index is 42 (interquartile range 28.25-58). There is a weak positive correlation between influence rank and h index (r = 0.23; p = 0.02). Limitations of the study include the inability to validate the accuracy of the proprietary ranking algorithm and investigation of just one social media platform. CONCLUSIONS: The top Twitter influencers in urology are mostly board-certified US urologists. Collectively, influencers have a relatively greater academic impact in comparison to the average urologist, although there is a weak positive correlation between Twitter influence and h index among top Twitter influencers. PATIENT SUMMARY: Given the explosion of medical information on Twitter, we report the personal accounts with the greatest impact for the topic of "urology". We found that most urology influencers on Twitter are US board-certified urologists with a strong research history.

Who Is Shaping the Future of Academic Urology? A Descriptive Analysis of Residency Program Directors.

OBJECTIVE: To characterize the demographics, educational background, and scholarly characteristics of current urology residency program directors (PDs). METHODS: Urology programs were identified by the listing on the "Accredited US Urology Programs" section of American Urological Association website as of October 2021. Demographics and academic data were collected via publicly available department website and Google search engine. Metrics obtained included years of service as PD from time of appointment, sex, medical school/residency/fellowship, all-time H-index, dual degrees obtained, and professorial ranking. RESULTS: One hundred and forty-seven accredited urological residencies were reviewed; every PD was included. The majority were male (78%) and fellowship trained (68%). Women represented only 22% of PDs. The median active time served as PD, as of 11/2021, was 4years (IQR: 2-7). Forty (28%) were faculty at the same program they completed their residency. The median all-time H-index was 12 (IQR: 7-19; range 1-61). Twelve PDs also served as chair of their department. CONCLUSION: The vast majority of PDs are male, fellowship trained, and have served for less than 5years. Future studies are necessary to follow the trends of representation in leaders of urology residency programs.

Benefit of lymph node dissection in cN+ patients in the treatment of upper tract urothelial carcinoma: Analysis of NCDB registry.

OBJECTIVES: The benefits of lymph node dissection (LND) in surgically treated upper tract urothelial carcinoma (UTUC) patients who present with clinically positive nodes at diagnosis remain unclear. The aim of this study was to assess survival differences in cN+ patients who underwent radical nephroureterectomy (RNU) with LND vs. without LND. METHODS: The National Cancer Database was used to identify a total number of 423 cN+ patients from 2004 to 2016 with UTUC that underwent RNU. Of the 423 patients, 310 received LND. Kaplan-Meier (KM) plots were used to estimate survival in cN+ patients who received RNU with LND vs. without. Cox proportional hazards regression tested the impact of LND status on overall survival (OS) after adjusting for all available covariates. RESULTS: Median age of the patient population was 68 years (IQR 61-76), and 56.74% were male. Median follow-up was 1.8 years (IQR 0.9-3.5). For the entire cohort, the 2-year OS rate was 51.8%, and it was 52.1% vs. 51.1% in patients who underwent LND vs. not (log-rank p-value=0.2). On multivariable analysis, performing LND had no statistically significant impact on OS (HR 0.93 95%CI 0.696-1.235, P = 0.9). Repeating the analysis in patients who had exclusively cN1 (HR 0.76 95%CI 0.469-1.223, P = 0.26) or cN2/3 (HR 0.844 95%CI 0.556-1.28, P = 0.43) disease also failed to demonstrate a significant impact of LND on survival. CONCLUSION: In cN+ patients with UTUC, performing LND in addition to RNU at any clinical stage does not seem to have a significant impact on OS.

Risk-Based Assessment Of the Impact Of Intravesical Therapy on Recurrence-Free Survival Rate Following Resection of Suspected Low-grade, Non-muscle-invasive Bladder Cancer (NMIBC): A Southwest Oncology Groups (SWOG) S0337 Posthoc Analysis.

BACKGROUND: Nonmuscle invasive bladder cancer (NMIBC) has an elevated risk of recurrence, and immediate postresection intravesical instillation of chemotherapy (IVC) significantly reduces the risk of recurrence. Questions remain about which subpopulation may maximally benefit from IVC. Our aim was to develop risk groups based on recurrence risk in NMIBC, and then evaluate the impact of a single, postoperative instillation of IVC on the subsequent risk of recurrence for each risk group. MATERIAL AND METHODS: Using the SWOG S0337 trial cohort, we performed a posthoc analysis of 345 patients who were diagnosed with suspected low-grade NMIBC, underwent transurethral resection of the bladder tumor (TURBT), and received post-operative IVC (gemcitabine vs. saline). Using regression tree analysis, the regression tree stratified patients based on their risk of recurrence into low-risk - single tumor and aged < 57 years, intermediate-risk - single tumor and aged ≥ 57 years, and high-risk - multiple tumors. We used Cox proportional hazard models to test the impact of recurrence-free rate, and after adjustment to available covariates. RESULTS: Median age of the cohort was 66.5 (IQR: 59.7-75.8 years) with 85% of patients being males. Median overall follow-up time was 3.07 years (IQR: 0.75-4.01 years). When testing the impact of treatment in each risk group separately, we found that patients in the intermediate-risk treated with gemcitabine had a 24-month recurrence free rate of 77% (95% CI: 68%-86%) vs. 59% (95% CI: 49%-70%) in the saline group. This survival difference was confirmed on multivariable analysis (hazard ratio: 0.39, 95% CI: 23%-66%, P < 0.001). This group represented 53% of our cohort. Conversely, we did not observe a significant difference in recurrence-free survival among patients in the low- (P = 0.7) and high-risk (P = 0.4) groups. CONCLUSION: Our findings indicate that older patients with a single tumor of suspected low-grade NMIBC at TURBT maximally benefit from immediate postresection IVC (gemcitabine).
