Prostate Cancer With Peritoneal Carcinomatosis: A Robotic-assisted Radical Prostatectomy-based Case Series.

OBJECTIVE: To aid in the diagnosis and treatment of patients with metastatic tumor seeding, an exceedingly rare phenomenon following minimally invasive urological surgery, additional case reports are needed. MATERIALS AND METHODS: We report our experience with patients determined to have peritoneal carcinomatosis following robotic-assisted radical prostatectomy (RARP) and provide a descriptive summary of these unique cases. RESULTS: Five cases of peritoneal carcinomatosis were identified, all of which occurred relatively late-between 8 and 13 years-following RARP. Four of the 5 cases had T3 disease at the time of prostatectomy. 68Ga-PSMA PET identified peritoneal carcinomatosis in 3 of 5 cases. CONCLUSION: Certain clinical factors, such as advanced pathologic stage at the time of prostatectomy, may predict risk for carcinomatosis following RARP. Additionally, next-generation imaging modalities, such as PSMA PET, may aid in identifying these metastases and are likely to identify increasing numbers of these patients as next-generation imaging becomes more widely available. Continued documentation and classification of this atypical presentation are needed to improve our understanding and management of this phenomenon.

Patient-reported impact of symptoms in Huntington disease: PRISM-HD.

OBJECTIVE: To determine the frequency and relative importance of symptoms experienced by adults with Huntington disease (HD) and to identify factors associated with a higher disease burden. METHODS: We performed 40 qualitative interviews (n = 20 with HD, n = 20 caregivers) and analyzed 2,082 quotes regarding the symptomatic burden of HD. We subsequently performed a cross-sectional study with 389 participants (n = 156 with HD [60 of whom were prodromal], n = 233 caregivers) to assess the prevalence and relative importance (scale 0-4) of 216 symptoms and 15 symptomatic themes in HD. Cross-correlation analysis was performed based on sex, disease duration, age, number of CAG repeats, disease burden, Total Functional Capacity score, employment status, disease status, and ambulatory status. RESULTS: The symptomatic themes with the highest prevalence in HD were emotional issues (83.0%), fatigue (82.5%), and difficulty thinking (77.0%). The symptomatic themes with the highest relative importance to participants were difficulty thinking (1.91), impaired sleep or daytime sleepiness (1.90), and emotional issues (1.81). High Total Functional Capacity scores, being employed, and having prodromal HD were associated with a lower prevalence of symptomatic themes. Despite reporting no clinical features of the disease, prodromal individuals demonstrated high rates of emotional issues (71.2%) and fatigue (69.5%). There was concordance between the prevalence of symptoms reported by manifest individuals and caregivers. CONCLUSIONS: Many symptomatic themes affect the lives of those with HD. These themes have a variable level of importance to the HD population and are identified both by those with HD and by their caregivers.

Assessing the feasibility of a chatbot after ureteroscopy.

BACKGROUND: Patients experience common symptoms and/or complications after undergoing ureteroscopy, which is a common procedure used to treat kidney stones. Current methods for patient education regarding these complications include counseling and discharge materials. This study aimed to assess chatbot usage and their ability to deliver information to patient post-ureteroscopy. METHODS: Patients who underwent ureteroscopy at the University of Michigan were given instructions to activate the chatbot. Within one to four weeks of their surgery, semi-structured interviews were conducted regarding post-surgical recovery and chatbot usage. RESULTS: Twenty patients were interviewed, seven of whom activated the chatbot. Frequent reasons for not activating the chatbot included misplacing instructions for chatbot use (n=6), relying on follow-up with clinic or discharge materials (n=4), inability to activate chatbot (n=2), and inability to text (n=1). Perceived benefits included alleviation of concerns surrounding common symptoms and quick access to information for non-emergent issues. CONCLUSIONS: These results suggest that chatbots are a convenient method to address common concerns post-ureteroscopy. However, better integration in the flow of care delivery and improved usability are needed to increase patient engagement.
