Plant-based diets, animal agriculture, and the connection with urological and planetary health.

PURPOSE OF REVIEW: We summarize the latest evidence regarding the impact of plant-based diets on urological and planetary health to facilitate patient counseling and research regarding dietary intervention. RECENT FINDINGS: Studies have highlighted the association of plant-based diets with a lower risk of multiple urological conditions including prostate cancer, erectile dysfunction, benign prostatic hyperplasia, and nephrolithiasis, as well as benefits for planetary health. SUMMARY: Plant-based diets are associated with numerous benefits that co-promote urological and planetary health.

Plant-Based Diets and Disease Progression in Men With Prostate Cancer.

Importance: Plant-based diets are associated with many health and environmental benefits, including primary prevention of fatal prostate cancer, but less is known about postdiagnostic plant-based diet patterns in individuals with prostate cancer. Objective: To examine whether postdiagnostic plant-based dietary patterns are associated with risk of prostate cancer progression and prostate cancer-specific mortality. Design, Setting, and Participants: This longitudinal observational cohort study included men with biopsy-proven nonmetastatic prostate cancer (stage ≤T3a) from the diet and lifestyle substudy within the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) enrolled at 43 urology practices across the US from 1999 to 2018. Participants completed a comprehensive diet and lifestyle questionnaire (including a validated food frequency questionnaire [FFQ]) between 2004 and 2016. Data were analyzed from August 2022 to April 2023. Exposures: Overall plant-based diet index (PDI) and healthful plant-based diet index (hPDI) scores were calculated from the FFQ. Main Outcomes and Measures: The primary outcome was prostate cancer progression (recurrence, secondary treatment, bone metastases, or prostate cancer-specific mortality). The secondary outcome was prostate cancer-specific mortality. Results: Among 2062 participants (median [IQR] age, 65.0 [59.0-70.0] years), 61 (3%) identified as African American, 3 (<1%) identified as American Indian or Alaska Native, 9 (<1%) identified as Asian or Pacific Islander, 15 (1%) identified as Latino, and 1959 (95%) identified as White. Median (IQR) time from prostate cancer diagnosis to FFQ was 31.3 (15.9-62.0) months after diagnosis. During a median (IQR) follow-up of 6.5 (1.3-12.8) years after the FFQ, 190 progression events and 61 prostate cancer-specific mortality events were observed. Men scoring in the highest vs lowest quintile of PDI had a 47% lower risk of progression (HR, 0.53; 95% CI, 0.37-0.74; P for trend = .003). The hPDI was not associated with risk of progression overall. However, among 680 individuals with Gleason grade 7 or higher at diagnosis, the highest hPDI quintile was associated with a 55% lower risk of progression compared with the lowest hPDI quintile (HR 0.45; 95% CI, 0.25-0.81; P for trend = .01); no association was observed in individuals with Gleason grade less than 7. Conclusions and Relevance: In this cohort study of 2062 men with prostate cancer, higher intake of plant foods after prostate cancer diagnosis was associated with lower risk of cancer progression. These findings suggest nutritional assessment and counseling may be recommended to patients with prostate cancer to help establish healthy dietary practices and support well-being and overall health.

Development and Validation of a Survey to Assess Sexual Health in Female Partners of Patients with Prostate Cancer.

BACKGROUND: Prostate cancer (PCa) diagnosis and treatment can have a significant negative impact on sexual health, affecting patients and their partners; however, the impact on partners is insufficiently addressed in current practice. OBJECTIVE: We describe the development and validation of an instrument to measure sexual health in female partners of patients with PCa. DESIGN, SETTING, AND PARTICIPANTS: Questions assessing sexual health were developed through a literature review, two qualitative studies, and an expert consensus process. Candidate survey items were tested through cognitive interviews and used to iteratively refine the questionnaire. INTERVENTION: The final questionnaire was tested in a validation study among 200 female partners. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We performed an exploratory factor analysis, followed by an analysis for internal validity, test-retest reliability, and convergent and discriminant validity. RESULTS AND LIMITATIONS: An initial set of 32 items was developed and refined through cognitive interviews. The resulting 27-item questionnaire was tested among 200 female partners of patients with PCa from across the USA. The exploratory factor analysis eliminated eight items and revealed seven key factors: (1) distress/satisfaction, (2) loss of connection as a couple, (3) active communication, (4) discomfort with communication, (5) frustration with sexual counseling, (6) expansion of sexual repertoire, and (7) nonpenetrative sexual activity. The overall scale demonstrated strong internal consistency (ordinal alpha 0.94) and test-retest reliability (0.89). Strengths of the study include development and evaluation of the first questionnaire to evaluate sexual quality of life among female partners of patients with PCa. However, additional work is needed to assess sexual health and quality of life among male and nonbinary partners. CONCLUSIONS: We developed a new instrument, the Sexual Concerns In Partners of Patients with Prostate cancer (SCIPPP-F), and found it to be valid in a diverse sample of female partners across the USA. PATIENT SUMMARY: Our new instrument can be used to characterize sexual health among female partners of patients with prostate cancer.

Engaging in Clinical Research and Practice Approaches that Reduce Environmental Impact.

Telemedicine, virtual conferences, and reducing waste in the operating room are ways in which urologists can reduce their environmental impact in daily practice. Patient counseling should also consider advice that simultaneously promotes overall, urological, and planetary health, such as plant-based diets and active transport.

PRECISE Version 2: Updated Recommendations for Reporting Prostate Magnetic Resonance Imaging in Patients on Active Surveillance for Prostate Cancer.

BACKGROUND AND OBJECTIVE: The Prostate Cancer Radiological Estimation of Change in Sequential Evaluation (PRECISE) recommendations standardise the reporting of prostate magnetic resonance imaging (MRI) in patients on active surveillance (AS) for prostate cancer. An international consensus group recently updated these recommendations and identified the areas of uncertainty. METHODS: A panel of 38 experts used the formal RAND/UCLA Appropriateness Method consensus methodology. Panellists scored 193 statements using a 1-9 agreement scale, where 9 means full agreement. A summary of agreement, uncertainty, or disagreement (derived from the group median score) and consensus (determined using the Interpercentile Range Adjusted for Symmetry method) was calculated for each statement and presented for discussion before individual rescoring. KEY FINDINGS AND LIMITATIONS: Participants agreed that MRI scans must meet a minimum image quality standard (median 9) or be given a score of 'X' for insufficient quality. The current scan should be compared with both baseline and previous scans (median 9), with the PRECISE score being the maximum from any lesion (median 8). PRECISE 3 (stable MRI) was subdivided into 3-V (visible) and 3-NonV (nonvisible) disease (median 9). Prostate Imaging Reporting and Data System/Likert ≥3 lesions should be measured on T2-weighted imaging, using other sequences to aid in the identification (median 8), and whenever possible, reported pictorially (diagrams, screenshots, or contours; median 9). There was no consensus on how to measure tumour size. More research is needed to determine a significant size increase (median 9). PRECISE 5 was clarified as progression to stage ≥T3a (median 9). CONCLUSIONS AND CLINICAL IMPLICATIONS: The updated PRECISE recommendations reflect expert consensus opinion on minimal standards and reporting criteria for prostate MRI in AS. PATIENT SUMMARY: The Prostate Cancer Radiological Estimation of Change in Sequential Evaluation (PRECISE) recommendations are used in clinical practice and research to guide the interpretation and reporting of magnetic resonance imaging for patients on active surveillance for prostate cancer. An international panel has updated these recommendations, clarified the areas of uncertainty, and highlighted the areas for further research.

TARGET: A Randomized, Noninferiority Trial of a Pretest, Patient-Driven Genetic Education Webtool Versus Genetic Counseling for Prostate Cancer Germline Testing.

PURPOSE: Germline genetic testing (GT) is important for prostate cancer (PCA) management, clinical trial eligibility, and hereditary cancer risk. However, GT is underutilized and there is a shortage of genetic counselors. To address these gaps, a patient-driven, pretest genetic education webtool was designed and studied compared with traditional genetic counseling (GC) to inform strategies for expanding access to genetic services. METHODS: Technology-enhanced acceleration of germline evaluation for therapy (TARGET) was a multicenter, noninferiority, randomized trial (ClinicalTrials.gov identifier: NCT04447703) comparing a nine-module patient-driven genetic education webtool versus pretest GC. Participants completed surveys measuring decisional conflict, satisfaction, and attitudes toward GT at baseline, after pretest education/counseling, and after GT result disclosure. The primary end point was noninferiority in reducing decisional conflict between webtool and GC using the validated Decisional Conflict Scale. Mixed-effects regression modeling was used to compare decisional conflict between groups. Participants opting for GT received a 51-gene panel, with results delivered to participants and their providers. RESULTS: The analytic data set includes primary outcome data from 315 participants (GC [n = 162] and webtool [n = 153]). Mean difference in decisional conflict score changes between groups was -0.04 (one-sided 95% CI, -∞ to 2.54; P = .01), suggesting the patient-driven webtool was noninferior to GC. Overall, 145 (89.5%) GC and 120 (78.4%) in the webtool arm underwent GT, with pathogenic variants in 15.8% (8.7% in PCA genes). Satisfaction did not differ significantly between arms; knowledge of cancer genetics was higher but attitudes toward GT were less favorable in the webtool arm. CONCLUSION: The results of the TARGET study support the use of patient-driven digital webtools for expanding access to pretest genetic education for PCA GT. Further studies to optimize patient experience and evaluate them in diverse patient populations are warranted.

Plant-based diet associated with better quality of life in prostate cancer survivors.

BACKGROUND: Plant-based diets have many health benefits, including a lower risk of fatal prostate cancer, and greater environmental sustainability. However, less is known regarding the impact of plant-based diets on quality of life among individuals diagnosed with prostate cancer. The authors' objective was to examine the relationship between plant-based diet indices postdiagnosis with quality of life. METHODS: This prospective cohort study included 3505 participants in the Health Professionals Follow-Up Study (1986-2016) with nonmetastatic prostate cancer. Food-frequency questionnaires were used to calculate overall and healthful plant-based diet indices. Quality-of-life scores were calculated using the Expanded Prostate Cancer Index Composite. Generalized estimating equations were used to examine associations over time between plant-based diet indices and quality-of-life domains (sexual functioning, urinary irritation/obstruction, urinary incontinence, bowel functioning, hormonal/vitality), adjusted for demographics, oncologic history, body mass index, caloric intake, health-related behaviors, and comorbidities. RESULTS: The median age at prostate cancer diagnosis was 68 years; 48% of patients underwent radical prostatectomy, and 35% received radiation as primary therapy. The median time from diagnosis/treatment to first the quality-of-life questionnaire was 7.0 years. A higher plant-based diet index was associated with better scores for sexual function, urinary irritation/obstruction, urinary incontinence, and hormonal/vitality. Consuming more healthful plant-based foods was also associated with better sexual and bowel function, as well as urinary incontinence and hormonal/vitality scores in the age-adjusted analysis, but not in the multivariable analysis. CONCLUSIONS: This prospective study provides supportive evidence that greater consumption of healthful plant-based foods is associated with modestly higher scores in quality-of-life domains among patients with prostate cancer.

Qualitative Study on Internet Use and Care Impact for Black Men With Prostate Cancer.

Black men have a greater risk of prostate cancer as well as worse quality of life and more decisional regret after prostate cancer treatment compared to non-Hispanic White men. Furthermore, patients with prostate cancer who primarily obtain information on the internet have significantly more decisional regret compared to other information sources. Our objective was to explore the perspectives of Black patients on the use and impact of the internet for their prostate cancer care. In 2022-2023, we conducted seven virtual focus groups with Black patients with prostate cancer (n = 22). Transcripts were independently analyzed by two experienced researchers using a constant comparative method. Online sources were commonly used by participants throughout their cancer journey, although informational needs varied over time. Patient factors affected use (e.g., physical health and experience with the internet), and family members played an active role in online information-seeking. The internet was used before and after visits to the doctor. Key topics that participants searched for online included nutrition and lifestyle, treatment options, and prostate cancer in Black men. Men reported many downstream benefits with internet use including feeling more empowered in decision-making, reducing anxiety about treatment and providing greater accountability for research. However, they also reported negative impacts such as feeling overwhelmed or discouraged sorting through the information to identify high-quality content that is personally relevant, as well as increased anxiety or loss of sleep from overuse. In summary, online sources have the potential to positively impact the cancer journey by reinforcing or supplementing information from health care providers, but can be harmful if the information is poor quality, not representative, or the internet is overused.

Representation Matters: Trust in Digital Health Information Among Black Patients With Prostate Cancer.

PURPOSE: Although the majority of US adults obtain health information on the internet, the quality of information about prostate cancer is highly variable. Black adults are underrepresented in online content about prostate cancer despite a higher incidence of and mortality from the disease. The goal of this study was to explore the perspectives of Black patients with prostate cancer on the importance of racial representation in online content and other factors influencing trust. MATERIALS AND METHODS: We conducted 7 virtual focus groups with Black patients with prostate cancer in 2022 and 2023. Participants completed an intake questionnaire with demographics followed by a group discussion, including feedback on purposefully selected online content. Transcripts were independently analyzed by 2 investigators experienced in qualitative research using a constant comparative method. RESULTS: Most participants use online sources to look for prostate cancer information. Racial representation is an important factor affecting trust in the content. A lack of Black representation has consequences, including misperceptions about a lower risk of prostate cancer and discouraging further information-seeking. Other key themes affecting trust in online content included the importance of a reputable source of information, professional website structure, and soliciting money. CONCLUSIONS: Underrepresentation of Black adults in prostate cancer content has the potential to worsen health disparities. Optimal online communications should include racially diverse representation and evidence-based information in a professional format from reputable sources without financial conflict.

Experiences of oncology researchers in the Veterans Health Administration during the COVID-19 pandemic.

The Veterans Health Administration is chartered "to serve as the primary backup for any health care services needed…in the event of war or national emergency" according to a 1982 Congressional Act. This mission was invoked during the COVID-19 pandemic to divert clinical and research resources. We used an electronic mixed-methods questionnaire constructed using the Theoretical Domains Framework (TDF) and the Capability, Opportunity, and Motivation (COM-B) model for behavior change to study the effects of the pandemic on VHA researchers. The questionnaire was distributed electronically to 118 cancer researchers participating in national VHA collaborations. The questionnaire received 42 responses (36%). Only 36% did not feel that their research focus changed during the pandemic. Only 26% reported prior experience with infectious disease research, and 74% agreed that they gained new research skills. When asked to describe helpful support structures, 29% mentioned local supervisors, mentors, and research staff, 15% cited larger VHA organizations and 18% mentioned remote work. Lack of timely communication and remote work, particularly for individuals with caregiving responsibilities, were limiting factors. Fewer than half felt professionally rewarded for pursuing research related to COVID. This study demonstrated the tremendous effects of the COVID-19 pandemic on research activities of VHA investigators. We identified perceptions of insufficient recognition and lack of professional advancement related to pandemic-era research, yet most reported gaining new research skills. Individualizing the structure of remote work and ensuring clear and timely team communication represent high yield areas for improvement.

Addressing gaps in healthcare provider knowledge regarding germline testing for prostate cancer through development and testing of a virtual genetics board.

BACKGROUND: Germline testing is important in prostate cancer and evaluation can be complex. METHODS: We instituted a monthly multi-disciplinary virtual genetics tumor board (7/2021-3/2022). Participants and panelists were surveyed on usefulness and acceptability. RESULTS: 101 participants attended a session, and 77 follow-up surveys were completed. Over 90% participants and 100% panelists endorsed usefulness of the case discussions and usability of the technology. The majority felt it provided new information they will use. CONCLUSIONS: A multidisciplinary genetics board was successfully developed to address complexity in prostate cancer genetics. The virtual platform may enhance dissemination of expertise where there are regional gaps.

Shared decision-making before prostate cancer screening decisions.

Decisions around prostate-specific antigen screening require a patient-centred approach, considering the benefits and risks of potential harm. Using shared decision-making (SDM) can improve men's knowledge and reduce decisional conflict. SDM is supported by evidence, but can be difficult to implement in clinical settings. An inclusive definition of SDM was used in order to determine the prevalence of SDM in prostate cancer screening decisions. Despite consensus among guidelines endorsing SDM practice, the prevalence of SDM occurring before the decision to undergo or forgo prostate-specific antigen testing varied between 11% and 98%, and was higher in studies in which SDM was self-reported by physicians than in patient-reported recollections and observed practices. The influence of trust and continuity in physician-patient relationships were identified as facilitators of SDM, whereas common barriers included limited appointment times and poor health literacy. Decision aids, which can help physicians to convey health information within a limited time frame and give patients increased autonomy over decisions, are underused and were not shown to clearly influence whether SDM occurs. Future studies should focus on methods to facilitate the use of SDM in clinical settings.

Patient experiences with tissue-based genomic testing during active surveillance for prostate cancer.

Background: Tissue-based gene expression (genomic) tests provide estimates of prostate cancer aggressiveness and are increasingly used for patients considering or engaged in active surveillance. However, little is known about patient experiences with genomic testing and its role in their decision-making. Methods: We performed a qualitative study consisting of in-depth, semi-structured interviews of patients with low- or favourable-intermediate-risk prostate cancer managed with active surveillance. We purposively sampled to include patients who received biopsy-based genomic testing as part of clinical care. The interview guide focused on experiences with genomic testing during patients' decision-making for prostate cancer management and understanding of genomic test results. We continued interviews until thematic saturation was reached, iteratively created a code key and used conventional content analysis to analyse data. Results: Participants' (n = 20) mean age was 68 years (range 51-79). At initial biopsy, 17 (85%) had a Gleason grade group 1, and 3 (15%) had a grade group 2 prostate cancer. The decision to undergo genomic testing was driven by both participants and physicians' recommendations; however, some participants were unaware that testing had occurred. Overall, participants understood the role of genomic testing in estimating their prostate cancer risk, and the test results increased their confidence in the decision for active surveillance. Participants had some misconceptions about the difference between tissue-based gene expression tests and germline genetic tests and commonly believed that tissue-based tests measured hereditary cancer risk. While some participants expressed satisfaction with their physicians' explanations, others felt that communication was limited and lacked sufficient detail. Conclusion: Patients interact with and are influenced by the results of biopsy-based genomic testing during active surveillance for prostate cancer, despite gaps in understanding about test results. Our findings indicate areas for improvement in patient counselling in order to increase patient knowledge and comfort with genomic testing.

Climate change perception and its association with cancer screening intent.

As the climate crisis deepens, its adverse effects on human health are becoming evident, including impacts on cancer pathogenesis and treatment. This study explored the link between individuals' awareness of the health impacts of climate change and interest in cancer screening. Using the 2021 Health Information National Trends Survey, our study demonstrated a statistically significant association between recognition of climate change as a personal health threat and interest in cancer screening. Although the study's retrospective nature and self-reported data pose some limitations, these findings signal a promising avenue for future research on the intersection of climate and cancer risk. This research supports the development of public health interventions that incorporate components of environmental health literacy alongside cancer screening efforts.

How Well Do Artificial Intelligence Chatbots Respond to the Top Search Queries About Urological Malignancies?

Artificial intelligence (AI) chatbots are becoming a popular source of information but there are limited data on the quality of information on urological malignancies that they provide. Our objective was to characterize the quality of information and detect misinformation about prostate, bladder, kidney, and testicular cancers from four AI chatbots: ChatGPT, Perplexity, Chat Sonic, and Microsoft Bing AI. We used the top five search queries related to prostate, bladder, kidney, and testicular cancers according to Google Trends from January 2021 to January 2023 and input them into the AI chatbots. Responses were evaluated for quality, understandability, actionability, misinformation, and readability using published instruments. AI chatbot responses had moderate to high information quality (median DISCERN score 4 out of 5, range 2-5) and lacked misinformation. Understandability was moderate (median Patient Education Material Assessment Tool for Printable Materials [PEMAT-P] understandability 66.7%, range 44.4-90.9%) and actionability was moderate to poor (median PEMAT-P actionability 40%, range 0-40%The responses were written at a fairly difficult reading level. AI chatbots produce information that is generally accurate and of moderate to high quality in response to the top urological malignancy-related search queries, but the responses lack clear, actionable instructions and exceed the reading level recommended for consumer health information. PATIENT SUMMARY: Artificial intelligence chatbots produce information that is generally accurate and of moderately high quality in response to popular Google searches about urological cancers. However, their responses are fairly difficult to read, are moderately hard to understand, and lack clear instructions for users to act on.

Prostate cancer and podcasts: an analysis and assessment of the quality of information about prostate cancer available on podcasts.

Podcasts represent a new source of information for patients and families dealing with prostate cancer, but no studies have been conducted evaluating the quality of information in them. Evaluating for: (1) quality based on the validated DISCERN criteria, (2) understandability and actionability based on the Patient Education Materials Assessment Tool (PEMAT), (3) misinformation, and (4) commercial bias, we concluded that podcasts are currently not good sources of information for lay health consumers.

Barriers and enablers of active surveillance for prostate cancer: a qualitive study of clinicians.

OBJECTIVES: To identify and explore barriers to, and enablers of, active surveillance (AS) in men with low-risk prostate cancer (LRPCa), as perceived by PCa clinicians. PATIENTS AND METHODS: Urologists and radiation oncologists in Australia and New Zealand were purposively sampled for a cross-section on gender and practice setting (metropolitan/regional; public/private). Using a grounded theory approach, semi-structed interviews were conducted with participants. Interviews were coded independently by two researchers using open, axial, and selective coding. A constant comparative approach was used to analyse data as it was collected. Thematic saturation was reached after 18 interviews, and a detailed model of barriers to, and enablers of, AS for LRPCa, as perceived by clinicians was developed. RESULTS: A model explaining what affects clinician decision making regarding AS in LRPCa emerged. It was underpinned by three broad themes: (i) clinician perception of patients' barriers and enablers; (ii) clinician perception of their own barriers and enablers; and (iii) engagement with healthcare team and resource availability. CONCLUSIONS: Clinicians unanimously agree that AS is an evidence-based approach for managing LRPCa. Despite this many men do not undergo AS for LRPCa, which is due to the interplay of patient and clinician factors, and their interaction with the wider healthcare system. This study identifies strategies to mitigate barriers and enhance enablers, which could increase access to AS by patients with LRPCa.

Unmet Sexual Health Resource Needs and Preferences for Interventions to Address These Needs Among Female Partners of Patients With Prostate Cancer.

OBJECTIVE: To characterize unmet sexual health resource needs and preferences for interventions to address unmet needs among female partners of patients with prostate cancer (PCa), given the significant negative impact of PCa on the sexual health of partners. METHODS: We conducted an exploratory sequential mixed methods study of female partners recruited from multiple U.S. clinical locations, websites, and support groups for caregivers. We first conducted semistructured in-depth interviews. Qualitative results informed development of a cross-sectional survey, which was administered to a larger sample of partners. RESULTS: Overall, 12 and 200 female partners participated in the qualitative and quantitative portions of the study. Major emergent themes from interviews were the benefits and drawbacks of technology-based interventions, the importance of sexual health resources throughout the PCa journey, and a desire for sexual health support groups that include partners. In the survey, the most common sexual health topics that partners wanted more information about were male libido problems (30.0%), erectile dysfunction (26.5%), and female libido and arousal problems (24.5%). Additionally, 41.5% wanted more information about sexual health websites, 35.0% about partners-only support groups, 29.5% about support groups for couples, and 23.5% about sexual medicine specialists. CONCLUSIONS: To our knowledge, this is the largest study to date on female partners' unmet sexual health resource needs and preferences for sexual health interventions. Partners prefer technology-based interventions, desire sexual health-focused support groups, and want more information about a variety of sexual issues and specialists who treat them.
