AUA Guideline Committee Members Determine Quality of Artificial Intelligence‒Generated Responses for Female Stress Urinary Incontinence.

INTRODUCTION: Stress urinary incontinence (SUI) affects countless women worldwide. Given ChatGPT's rising ubiquity, patients may turn to the platform for SUI advice. Our objective was to evaluate the quality of clinical information about SUI from the ChatGPT platform. METHODS: The most-asked patient questions regarding SUI were derived from patient materials from societal websites and forums, and queried using ChatGPT 3.5. The responses from ChatGPT were compiled into a survey and disseminated to 3 AUA guideline committee members who developed the Surgical Management of Female SUI guidelines. They were asked to grade responses on reliability, understandability, quality, and actionability using DISCERN and Patient Education Materials Assessment Tool standardized questionnaires. Accuracy was assessed with a 4-point Likert scale and readability using Flesch Reading Ease score. RESULTS: The overall material was rated as moderate to moderately high quality (DISCERN = 3.73/5) with potentially important but no serious shortcomings. Reliability and quality were reported to be 63% and 75%. Understandability was 89%, actionability 18%, and accuracy 88%. All question domains were rated at moderate or better. Actionability was poor in all domains. Every response was "hard to read" translating to a college graduate reading level. CONCLUSIONS: The urologic community should critically evaluate this platform's output if patients are to use it for adjunctive medical guidance. AUA committee members, who are experts in the field, rate ChatGPT-produced responses on SUI as moderate to moderately high quality, moderate reliability, excellent understandability, and poor actionability utilizing standardized questionnaires. The reading level of the material was advanced, which is an area of potential improvement to make generated responses more comprehensible.

Bilateral epidural D-wave monitoring during resection of an eccentric cervical astrocytoma with evidence of asymmetrical corticospinal desynchronization.

BACKGROUND AND IMPORTANCE: The surgical management of intramedullary spinal cord tumours (IMSCT) poses inherent risk to neurologic function. Direct-wave (D-wave) monitoring is routinely reported to be a robust prognostic measure of spinal cord function via midline recording within the epidural or intradural space in a cranial-caudal montage. We explored the feasibility of bilateral epidural D-wave monitoring with routine evoked potentials in promoting safe and maximal resection in a patient with diminished midline D-wave baselines associated with an eccentric intramedullary cervical astrocytoma. CLINICAL PRESENTATION: We describe the presentation, surgical management, electrophysiological findings and post-operative outcome of a 46 year-old female patient who underwent two resections for an eccentric intramedullary cervical astrocytoma. During the first procedure we encountered clinically significant motor evoked potential signal change and discontinuation of resection pending further review. Midline D-wave signals showed no change, however peak amplitude was diminutive (7 uV) and overall morphology was characteristic of corticospinal desynchronization. Post-operatively the patient experienced significant but transient left sided weakness. A subsequent revision procedure incorporating ipsilesional and contralesional D-wave monitoring in addition to routinely incorporated evoked potentials was proposed in order to facilitate a safer resection. The ipsilesional D-wave response was considerably lower in amplitude (2.5 uV) in contrast to the contralesional D-wave (20 uV). CONCLUSION: To the authors' knowledge this is the first description of bilateral D-wave monitoring as an adjunct to cranial-caudal D-wave montages during IMSCT surgery. In patients with corticospinal desynchronization evidenced by abnormal midline D-wave morphology, bilateral D-wave monitoring in conjunction with routine evoked potentials may be clinically indicated for preservation of motor function and promotion of safe and maximal resection.

Disagreement in Female Urethral Nomenclature: A Survey Study of Genitourinary Surgeons.

Introduction: Inconsistencies exist in the nomenclature pertaining to the terms dorsal and ventral female urethra. This survey study was devised to demonstrate this inconsistency, and to identify any surgeon characteristics that contribute to this confusion in urologic and gynecologic reconstructive surgeons.Methods: Genitourinary surgeons were anonymously surveyed using email and social media platforms and asked how they would anatomically label 2 distinctly indicated regions of the female urethra using "dorsal" and "ventral" nomenclature. χ2 statistical analyses were used to compare categorical responses.Results: We received a total of 155 responses: 128 urologists, 26 gynecologists, and 1 medical student. The medical student was excluded from the analysis. Responses to the red/dorsal marker were 48% dorsal, 27% ventral, and 25% free response. Responses to the green/ventral marker were 52% ventral, 26% dorsal, and 22% free response. Urologists were more likely than gynecologists to use the correct "dorsal" label (χ2 [1, N = 122] = 33.6, P < .00001) and "ventral" label (χ2 [1, N = 124] = 32.3, P < .00001). There was no statistically significant difference between attendings vs trainees responding either "dorsal" or "ventral" to describe the red marker (χ2 [1, N = 124] = 0.24, P < .63) or the green marker (χ2 [1, N = 122] = 0.21, P < .65).Conclusions: The terms dorsal and ventral female urethra are not consistent between urologist and gynecologist reconstructive surgeons, and efforts to standardize terminology should be made at the residency training level.

Dermatology medications with the highest cost burden on Medicare Part D: Potential implications of the Inflation Reduction Act.

Signed into law in August 2022, the Inflation Reduction Act includes provisions requiring the federal government to negotiate prices for medications covered under Medicare Part D. Initial negotiations will target drugs with the highest total spending and price increases relative to inflation. In this study, we identify dermatology prescriptions with the highest cost burden on Medicare Part D and analyze recent trends in total spending and unit costs.

Promoting new users' online health consultation services usage behavior strategically.

Online consultation services have the potential to reduce the workload of healthcare staff, provide timely care to patients, and improve doctor-patient relationships. The COVID-19 pandemic has accelerated the development of these services and platforms, but it remains to be seen whether the general public will continue to use them after the pandemic is under control. This research proposes a framework to examine the factors contributing to UK adults' continued usage of online healthcare consultation services after COVID-19 restrictions have been lifted. A total of 430 new users completed surveys, and the results indicate that expectation confirmation, system quality, and information quality can positively impact users' self-efficacy toward using online consultation services. This, in turn, can influence their continued usage behavior. Furthermore, the results suggest that participants' perception of health risks can moderate the relationship between self-efficacy and continued usage behavior. The strategic implications of these findings are discussed.

Mobile App Use among Persons with Fibromyalgia: A Cross-sectional Survey.

Persons with fibromyalgia experience a diverse set of symptoms. Recommendations for management generally focus on multidisciplinary approaches involving multiple modalities. Mobile apps can be an essential component for self-management, yet little is known about how persons with fibromyalgia use mobile apps for health-related purposes. A cross-sectional survey (N = 663) was conducted to understand the real-world use of apps among persons with fibromyalgia. The survey included 2 main foci: 1) eHealth literacy and use of information sources, and 2) mobile app use patterns and preferences for health-related purposes, including the types of apps used and usage characteristics of apps currently in use, as well as those that had been discontinued. Respondents' average eHealth literacy as measured by eHealth Literacy Scale (eHEALS) was 31.4 (SD = 7.1), and they utilized diverse information sources. Approximately two-thirds of the sample used mobile apps; the remaining one-third did not. Diverse health management needs were represented in the apps reported, including scheduling/time management, notetaking, fitness, and wellness. Compared to apps that had been discontinued, participants rated apps that they still used higher in terms of ease of use and used them more frequently. Reasons for discontinuing app use included issues with privacy, the effort required, lack of interest, and lack of perceived quality. Other reasons for app nonuse were lack of awareness and how-to knowledge, indicating that disseminating information about apps and addressing other barriers, such as providing user support, are critical to increasing uptake. These study findings can inform both app design and dissemination. PERSPECTIVE: This article presents how persons with fibromyalgia use mobile apps to manage their health. The findings could inform the development of digital interventions or programs for this population.

Short-term outcomes of prehospital opioid pain management for older adults with fall-related injury.

BACKGROUND: Opioids are recommended for pain management in patients being cared for and transported by emergency medical services, but no specific guidelines exist for older adults with fall-related injury. Prior research suggests prehospital opioid administration can effectively manage pain in older adults, but less is known about safety in this population. We compared short-term safety outcomes, including delirium, disposition, and length of stay, among older adults with fall-related injury according to whether they received prehospital opioid analgesia. METHODS: We linked Medicare claims data with prehospital patient care reports for older adults (≥65) with fall-related injury in Illinois between January 1, 2014 and December 31, 2015. We used weighted regression models (logistic, multinomial logistic, and Poisson) to assess the association between prehospital opioid analgesia and incidence of inpatient delirium, hospital disposition, and length of stay. RESULTS: Of 28,150 included older adults, 3% received prehospital opioids. Patients receiving prehospital opioids (vs. no prehospital opioids) were less likely to be discharged home from the emergency department (adjusted probability = 0.30 [95% CI: 0.25, 0.34] vs. 0.47 [95% CI: 0.46, 0.48]), more likely to be discharged to a non-home setting after an inpatient admission (adjusted probability = 0.43 [95% CI: 0.39, 0.48] vs. 0.30 [95% CI: 0.30, 0.31]), had inpatient length of stay 0.4 days shorter (p < 0.001) and ICU length of stay 0.7 days shorter (p = 0.045). Incidence of delirium did not vary between treatment and control groups. CONCLUSIONS: Few older adults receive opioid analgesia in the prehospital setting. Prehospital opioid analgesia may be associated with hospital disposition and length of stay for older adults with fall-related injury. However, our findings do not provide evidence of an association with inpatient delirium. These findings should be considered when developing guidelines for prehospital pain management specific to the older adult population.

Cytologic features of canine melanotroph and corticotroph pituitary adenomas.

BACKGROUND: The introduction of intraoperative cytology revolutionized neurosurgical procedures in human medicine, providing real-time diagnostic guidance to surgeons and contributing to improved patient outcomes. In the realm of veterinary medicine, the understanding of pituitary tumors in dogs and cats remains limited due to challenges in obtaining antemortem samples of central nervous system lesions. OBJECTIVES: The aim of this study was to describe the cytologic features of pituitary adenomas in 12 dogs that underwent hypophysectomy. METHODS: The series included nine melanotroph adenomas and three corticotroph adenomas. Definitive diagnosis was based on histopathology and immunohistochemistry. RESULTS: Cytologically, the adenomas had high numbers of bare nuclei and intact cells that were round to polygonal and situated individually or in small clusters. The intact cells had round to oval, eccentric nuclei with finely stippled chromatin and one to three prominent nucleoli and ample to abundant lightly basophilic to amphophilic, grainy cytoplasm with distinct borders, and variable numbers of discrete vacuoles. Mild-to-moderate anisocytosis and anisokaryosis, occasional binucleation, rare and atypical mitotic figures, and nuclear molding were also observed. CONCLUSIONS: The results suggest that intraoperative cytology of canine pituitary adenomas holds promise as a valuable diagnostic tool, aiding swift differentiation from other sellar masses before histologic confirmation. Cytologic characterization of pituitary adenomas in dogs is exceptionally rare in the scientific literature, making this study one of the first to offer a comprehensive description of these cytologic features.

Metabolic dysregulation and gut dysbiosis linked to hyperandrogenism in female mice.

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a common endocrine pathology in women. In addition to infertility, women with PCOS have metabolic dysregulation which predisposes them to Type 2 diabetes, cardiovascular disease and non-alcoholic fatty liver disease. Moreover, women with PCOS have changes in their gut microbial community that may be indicative of dysbiosis. While hyperandrogenism is associated with both the development of metabolic dysfunction and gut dysbiosis in females, the mechanisms involved are not well understood. METHODS: We used dihydrotestosterone (DHT) and ovariectomy (OVX) mouse models coupled with metabolic assessments and 16S rRNA gene sequencing to explore the contributions of hyperandrogenism and oestrogen deficiency to the development of insulin resistance and gut microbial dysbiosis in pubertal female mice. RESULTS: We demonstrated that, while DHT treatment or OVX alone were insufficient to induce insulin resistance during the pubertal-to-adult transition, combining OVX with DHT resulted in insulin resistance similar to that observed in letrozole-treated mice with elevated testosterone and decreased oestrogen levels. In addition, our results showed that OVX and DHT in combination resulted in a distinct shift in the gut microbiome compared to DHT or OVX alone, suggesting that the substantial metabolic dysregulation occurring in the OVX + DHT model was accompanied by unique changes in the abundances of gut bacteria including S24-7, Rikenellaceae and Mucispirillum schaedleri. CONCLUSIONS: While hyperandrogenism plays an important role in the development of metabolic dysregulation in female mice, our results indicate that investigation into additional factors influencing insulin resistance and the gut microbiome during the pubertal-to-adult transition could provide additional insight into the pathophysiology of PCOS.

Risk perception and intended behavior change after uninformative genetic results for adult-onset hereditary conditions in unselected patients.

Population genetic screening for preventable adult-onset hereditary conditions may improve disease management and morbidity but most individuals will receive uninformative results that do not indicate higher risk for disease. Investigation into subsequent psychosocial health and behaviors is necessary to inform population screening feasibility, effectiveness, and cost considerations. We conducted a prospective survey study of unselected University of Washington Medicine patients enrolled in a genetic research study screening for pathogenic variation in medically important genes. Survey questions adapted from the Feelings About genomiC Testing Results (FACToR) questionnaire and designed to understand perceived disease risk change and planned health behaviors were administered after receipt of results. Overall, 2761 people received uninformative results and 1352 (49%) completed survey items. Respondents averaged 41 years old, 62% were female, and 56% were Non-Hispanic Asian. Results from the FACToR instrument showed mean (SD) scores of 0.92 (1.34), 7.63 (3.95), 1.65 (2.23), and 0.77 (1.50) for negative emotions, positive emotions, uncertainty, and privacy concerns, respectively, suggesting minimal psychosocial harms from genetic screening. Overall, 12.2% and 9.6% of survey respondents believed that their risk of cancer or heart disease, respectively, had changed after receiving their uninformative genetic screening results. Further, 8.5% of respondents planned to make healthcare changes and 9.1% other behavior changes. Future work is needed to assess observed behavior changes attributable to uninformative screening results and if small changes in behavior among this population have large downstream impacts.

Peripheral Transcriptomics in Acute and Long-Term Kidney Dysfunction in SARS-CoV2 Infection.

Background: Acute kidney injury (AKI) is common in hospitalized patients with SARS-CoV2 infection despite vaccination and leads to long-term kidney dysfunction. However, peripheral blood molecular signatures in AKI from COVID-19 and their association with long-term kidney dysfunction are yet unexplored. Methods: In patients hospitalized with SARS-CoV2, we performed bulk RNA sequencing using peripheral blood mononuclear cells(PBMCs). We applied linear models accounting for technical and biological variability on RNA-Seq data accounting for false discovery rate (FDR) and compared functional enrichment and pathway results to a historical sepsis-AKI cohort. Finally, we evaluated the association of these signatures with long-term trends in kidney function. Results: Of 283 patients, 106 had AKI. After adjustment for sex, age, mechanical ventilation, and chronic kidney disease (CKD), we identified 2635 significant differential gene expressions at FDR<0.05. Top canonical pathways were EIF2 signaling, oxidative phosphorylation, mTOR signaling, and Th17 signaling, indicating mitochondrial dysfunction and endoplasmic reticulum (ER) stress. Comparison with sepsis associated AKI showed considerable overlap of key pathways (48.14%). Using follow-up estimated glomerular filtration rate (eGFR) measurements from 115 patients, we identified 164/2635 (6.2%) of the significantly differentiated genes associated with overall decrease in long-term kidney function. The strongest associations were 'autophagy', 'renal impairment via fibrosis', and 'cardiac structure and function'. Conclusions: We show that AKI in SARS-CoV2 is a multifactorial process with mitochondrial dysfunction driven by ER stress whereas long-term kidney function decline is associated with cardiac structure and function and immune dysregulation. Functional overlap with sepsis-AKI also highlights common signatures, indicating generalizability in therapeutic approaches. SIGNIFICANCE STATEMENT: Peripheral transcriptomic findings in acute and long-term kidney dysfunction after hospitalization for SARS-CoV2 infection are unclear. We evaluated peripheral blood molecular signatures in AKI from COVID-19 (COVID-AKI) and their association with long-term kidney dysfunction using the largest hospitalized cohort with transcriptomic data. Analysis of 283 hospitalized patients of whom 37% had AKI, highlighted the contribution of mitochondrial dysfunction driven by endoplasmic reticulum stress in the acute stages. Subsequently, long-term kidney function decline exhibits significant associations with markers of cardiac structure and function and immune mediated dysregulation. There were similar biomolecular signatures in other inflammatory states, such as sepsis. This enhances the potential for repurposing and generalizability in therapeutic approaches.

Creatine kinase and its isoenzymes in the serum and cerebrospinal fluid of healthy canines.

BACKGROUND: Creatine kinase (CK) exists as three isoenzymes (CK-MM, CK-MB, and CK-BB) that are predominantly expressed in specific tissues and can be detected in both the serum and cerebrospinal fluid (CSF). CSF CK has been relatively unstudied in veterinary medicine, although studies in human medicine have demonstrated that changes in total CSF CK activity can indicate neurologic abnormalities. OBJECTIVES: The purpose of this study was to establish reference intervals for CK and its three major isoenzymes in the serum and CSF of clinically healthy dogs. By establishing a definitive reference interval for this enzyme in healthy canines, the diagnostic use and possible significance of CK in clinical disease can be studied. METHODS: Serum and/or CSF were collected from healthy dogs. Total CK activity was measured spectrophotometrically, and isoenzyme distributions were determined using the QuickGel CK Vis Isoenzyme Kit and a densitometric scanner. Total CK and CK isoenzyme activities were determined within 8 h of collection. RESULTS: The median serum total CK in healthy canines was 159.0 U/L (range: 53.0-539.0 U/L), while the median CSF total CK was 3.7 U/L (range: 2.0-84.0 U/L). CK-BB and CK-MM were approximately equal in the serum, while CK-MM was the predominant isoenzyme in the CSF. CONCLUSIONS: Knowledge of the normal distribution and concentration of CK in canine serum and CSF will set the foundation for future studies of canine CK as a potentially clinically useful biomarker.

Considering the Role of Information and Context in Promoting Health-Related Behavioral Change.

This poster considers the role that information and context may play in health management. We employ a well-known taxonomy of techniques for promoting behavioral change to consider how social media authors describe their recovery from substance use. We harvest discussion posts from subreddits, or discussion forums, about alcohol, cannabis, and opioids, and perform content analysis to identify behavioral change techniques (BCTs) described in the content. We then consider the role that the context of information use plays in these BCTs, as well as how interventions and technologies might be leveraged to better support the recovery process.

Novel COL6A3 frameshift variant in American Staffordshire Terrier dogs with Ullrich-like congenital muscular dystrophy.

Two (male and female) 10-month-old American Staffordshire Terrier littermates presented for progressive weakness, joint contracture, and distal limb joint hyperlaxity beginning around 6 months of age. Neurological examination, serum creatine kinase activity, infectious disease titers, cerebrospinal fluid analysis, and electrodiagnostic testing were performed. Muscle biopsies were collected for histopathology and immunofluorescence staining for localization of dystrophy associated proteins. Whole-genome sequencing (WGS) was performed on 1 affected dog. Variants were compared to a database of 671 unaffected dogs of multiple breeds. Histopathology confirmed a dystrophic phenotype and immunofluorescence staining of muscle cryosections revealed an absence of staining for collagen-6. WGS identified a homozygous 1 bp deletion in the COL6A3 gene, unique to the first affected dog. Sanger sequencing confirmed the homozygous presence of the frameshift variant in both affected dogs. This report describes the clinical features and most likely genetic basis of an Ullrich-like recessively inherited form of congenital muscular dystrophy in American Staffordshire Terriers.

Emergency department visits associated with wildfire smoke events in California, 2016-2019.

Wildfire smoke has been associated with adverse respiratory outcomes, but the impacts of wildfire on other health outcomes and sensitive subpopulations are not fully understood. We examined associations between smoke events and emergency department visits (EDVs) for respiratory, cardiovascular, diabetes, and mental health outcomes in California during the wildfire season June-December 2016-2019. Daily, zip code tabulation area-level wildfire-specific fine particulate matter (PM2.5) concentrations were aggregated to air basins. A "smoke event" was defined as an air basin-day with a wildfire-specific PM2.5 concentration at or above the 98th percentile across all air basin-days (threshold = 13.5 µg/m3). We conducted a two-stage time-series analysis using quasi-Poisson regression considering lag effects and random effects meta-analysis. We also conducted analyses stratified by race/ethnicity, age, and sex to assess potential effect modification. Smoke events were associated with an increased risk of EDVs for all respiratory diseases at lag 1 [14.4%, 95% confidence interval (CI): (6.8, 22.5)], asthma at lag 0 [57.1% (44.5, 70.8)], and chronic lower respiratory disease at lag 0 [12.7% (6.2, 19.6)]. We also found positive associations with EDVs for all cardiovascular diseases at lag 10. Mixed results were observed for mental health outcomes. Stratified results revealed potential disparities by race/ethnicity. Short-term exposure to smoke events was associated with increased respiratory and schizophrenia EDVs. Cardiovascular impacts may be delayed compared to respiratory outcomes.

Factors Influencing Genetic Screening Enrollment among a Diverse, Community-Ascertained Cohort.

INTRODUCTION: Genetic screening for preventable adult-onset hereditary conditions has been proposed as a mechanism to reduce health disparities. Analysis of how race and ethnicity influence decision-making to receive screening can inform recruitment efforts and more equitable population screening design. A study at the University of Washington Medicine that invited unselected patients to participate in genetic screening for pathogenic variation in medically important genes provided an opportunity to evaluate these factors. METHODS: We analyzed screening enrollee survey data to understand factors most important and least important in decision-making about screening overall and across different race and ethnicity groups. Electronic health record race and ethnicity and survey-reported race and ethnicity were compared to assist with interpretation. Comments provided about reasons for not enrolling in screening were analyzed using content analysis. RESULTS: Overall, learning about disease risk and identifying risk early for prevention purposes were important factors in decision-making to receive screening, and regrets about screening and screening being against one's moral code were not viewed as important. Although racial identity was challenging to assign in all cases, compared to other enrollees, African-American and Asian enrollees considered test accuracy and knowing more about the test to be of greater importance. Three themes emerged related to nonparticipation: benefits do not outweigh risks, don't want to know, and challenges with study logistics. CONCLUSION: Our results highlight important motivators for receiving screening and areas that can be addressed to increase screening interest and accessibility. This knowledge can inform future population screening program design including recruitment and education approaches.

Subscriptions and external links help drive resentful users to alternative and extremist YouTube channels.

Do online platforms facilitate the consumption of potentially harmful content? Using paired behavioral and survey data provided by participants recruited from a representative sample in 2020 (n = 1181), we show that exposure to alternative and extremist channel videos on YouTube is heavily concentrated among a small group of people with high prior levels of gender and racial resentment. These viewers often subscribe to these channels (prompting recommendations to their videos) and follow external links to them. In contrast, nonsubscribers rarely see or follow recommendations to videos from these channels. Our findings suggest that YouTube's algorithms were not sending people down "rabbit holes" during our observation window in 2020, possibly due to changes that the company made to its recommender system in 2019. However, the platform continues to play a key role in facilitating exposure to content from alternative and extremist channels among dedicated audiences.
