Biparametric versus multiparametric MRI for the detection of clinically significant prostate cancer in a diverse, multiethnic population.

PURPOSE: There is not yet satisfactory performance data comparing multiparametric MRI (mpMRI) versus biparametric MRI (bpMRI) for detecting prostate cancer (PCa), particularly in high-risk populations. We compared both protocols for detecting overall PCa and clinically significant PCa (CS-PCa; defined as Grade Group ≥ 2) in a multiethnic urban population. METHODS: We retrospectively reviewed electronic medical record data from men who underwent image-guided fusion prostate biopsy (FB) between 2016 and 2021 at our institution. Patient characteristics, Prostate Imaging Reporting and Data System (PI-RADS) scores, and FB outcomes were analyzed based on MRI protocol. Multivariate mixed-effects logistic regression models were used to examine associations of bpMRI versus mpMRI for detecting overall PCa and CS-PCa in targeted lesions, among all patients and stratified by race/ethnicity. RESULTS: Overall, 566 men (44.0% Non-Hispanic Black [NHB]; 27.0% Hispanic) with 975 PI-RADS 3-5 lesions on MRI underwent FB. Of these, 312 (55%) men with 497 lesions underwent mpMRI and 254 (45%) men with 478 lesions underwent bpMRI. On multivariate analyses among all men, the odds of detecting overall PCa (OR = 1.18, 95% CI: 1.05-3.11, p = 0.031) and CS-PCa (OR = 2.15, 95% CI: 1.16-4.00, p = 0.014) on FB were higher for lesions identified on bpMRI than mpMRI. When stratified by race/ethnicity, the odds of detecting overall PCa (OR = 1.86; p = 0.15) and CS-PCa (OR = 2.20; p = 0.06) were not statistically different between lesions detected on bpMRI or mpMRI. CONCLUSION: BpMRI has similar diagnostic performance to mpMRI in detecting overall and CS-PCa within a racially/ethnically diverse population. BpMRI can be utilized for evaluating suspected CS-PCa among NHB and Hispanic men.

Performance of cognitive vs. image-guided fusion biopsy for detection of overall and clinically significant prostate cancer in a multiethnic population.

PURPOSE: Transrectal ultrasound-guided prostate biopsy remains the most used method for the detection of prostate cancer. We recently reported that detection of clinically significant prostate cancer (cs-CaP) using image-guided fusion biopsies (IGFB) varied by race/ethnicity, which calls for further comparison between cognitive fusion biopsy (CFB) and IGFB among non-Hispanic black and Hispanic populations. Therefore, the aim of our study is to compare the rates of detection of cs-CaP and overall CaP by CFB and IGFB in a multiethnic community. MATERIAL AND METHODS: We performed a retrospective, cross-sectional review of men who underwent MRI-transrectal ultrasound-guided prostate biopsy at our diverse, urban academic medical center. Agreement and discordance between fusion biopsies and systematic biopsies for detection of cs-CaP and overall CaP were determined using Kappa statistics. Univariate and multivariate mixed-effects logistic regression models were used to find associations between fusion modalities and prostate cancer detection. RESULTS: In total, 710 men underwent fusion prostate biopsies between December 2015 and June 2021. Upon univariate and multivariate logistic regression analysis, there was no significant association between IGFB vs. CFB and risk of overall CaP (OR = 0.66, 95% CI: 0.36-1.21, P = 0.18) or cs-CaP (OR = 0.57, 95% CI: 0.30-1.08, P = 0.09). We found moderate agreement between fusion and systematic biopsies for both CFB (κ = 0.56) and IGFB (κ = 0.52) in cs-CaP. CONCLUSIONS: CFB and IGFB offer similar detection rates of cs-CaP in a multiethnic population. CFB represents an effective and accessible means of accurately diagnosing prostate cancer.

Development and validation of nomogram to improve the specificity of multiparametric MRI for clinically significant prostate cancer.

OBJECTIVE: To develop and validate a nomogram to improve the specificity of prostate imaging reporting and data system (PI-RADS) on multiparametric magnetic resonance imaging (MRI) for clinically significant prostate cancer on targeted fusion biopsy. METHODS: A retrospective review of patients who underwent fusion biopsy for PI-RADS 3-5 lesions using UroNav and Artemis systems between 2016 and 2022 was performed. Patients were divided into those with CS disease on fusion biopsy (Gleason grade group ≥2) versus those without. Multivariable analysis was used to identify variables associated with CS disease. A 100-point nomogram was constructed, and ROC curve was generated. RESULTS: 1485 lesions (1032 patients) were identified, 510 (34%) were PI-RADS 3, 586 (40%) were PI-RADS 4, and 389 (26%) were PI-RADS 5. Of these, 11% of PI-RADS 3, 39% of PI-RADS 4, and 61% of PI-RADS 5 showed CS disease. CS disease was associated with older age (OR 1.04, 95% CI 1.02-1.06, p < 0.01), previous negative biopsy (OR 0.52, 95% CI 0.36-0.74, p < 0.01), presence of multiple PI-RADS 3-5 lesions (OR 0.61, 95% CI 0.45-0.83, p < 0.01), peripheral zone location (OR 1.88, 95% CI 1.30-2.70, p < 0.01), PSA density (OR 1.48 per 0.1 unit, 95% CI 1.33-1.64, p < 0.01), PI-RADS score 4 (OR 3.28, 95% CI 2.21-4.87, p < 0.01), and PI-RADS score 5 (OR 7.65, 95% CI 4.93-11.85, p < 0.01). Area under ROC curve was 82% for nomogram compared to 75% for PI-RADS score alone. CONCLUSION: We report a nomogram that combines PI-RADS score with other clinical parameters. The nomogram outperforms PI-RADS score for the detection of CS prostate cancer.

Low risk is low risk, regardless of race or ethnicity: Outcomes of prostate cancer active surveillance and factors associated with reclassification in a racially diverse cohort.

INTRODUCTION: Active surveillance (AS) is the standard for very low- and low-risk prostate cancer. Although risk factors for pathologic reclassification while on AS have been identified, results are mixed for non-Hispanic Black (NHB) and Hispanic ethnicity. We aim to further explore how race and ethnicity may be affecting AS participation and outcomes in a primarily urban, diverse, and vulnerable population. MATERIALS AND METHODS: Patients eligible for AS from 2005-2020 were reviewed. Demographics, race/ethnicity, prostate specific antigen (PSA), prostate volume, and pathologic characteristics were analyzed between patients enrolled in AS and those that underwent immediate therapy. Kaplan-Meier survival analysis was used to compare biochemical recurrence (BCR) rates. Cox proportional hazards models were used to develop prediction models for clinical reclassification. RESULTS: A total of 471 men were eligible for AS. Of those, 188 (39.9%) enrolled in AS while 283 (60.1%) underwent immediate radical therapy. No significant differences were found in racial/ethnic composition between the AS and immediate treatment groups. In our AS cohort, 79 (42.0%) experienced clinical reclassification and underwent deferred treatment. BCR rates were similar between treatment groups. Race/ethnicity were not found to be predictors of clinical reclassification, while metrics at diagnostic biopsy such as elevated PSA, higher PSA density, and lower prostate volume increased reclassification odds. CONCLUSIONS: In our diverse population, NHB race and Hispanic ethnicity were not significant predictors of adverse reclassification while on AS. Our findings support utilizing other metrics taken at initial biopsy to identify high-risk patients such as PSA, prostate volume, and PSA density.

Imaging After Ureteroscopy: Practice Patterns, Patient Adherence and Impact on Subsequent Management in an Urban Academic Hospital System.

OBJECTIVE: To evaluate practice patterns of post-ureteroscopy (URS) imaging, to assess predictors of imaging order, type and completion, and to analyze impact on patient management. METHODS: We conducted a retrospective review of patients who underwent URS for nephrolithiasis at a single institution between May, 2020 to May, 2021. Patient demographic, clinical and operative characteristics were reviewed, and surgeons' years in practice. Post-URS imaging studies less than 6 months post-operative were reviewed. Changes in patient management were defined as additional imaging tests ordered or subsequent unplanned surgery. Patient, provider and surgical variables were compared between those who had imaging ordered and those who did not. RESULTS: A total of 289 patients underwent URS. About 234 (81.0%) had post-operative imaging ordered; 147 (62.8%) completed them. Baseline demographics, stone and surgical variables were similar among those who did and did not have imaging ordered and among patients who completed imaging and did not. Pre-operative hydronephrosis was associated with ordering of post-operative imaging (OR = 4.08, P = .01). Urologists in practice less than 5 years were more likely to order post-operative imaging compared to those in practice for more than 5 years (<5: 90.6%, 15+: 53.7%; P <.001). Management changed for 52 of 147 (35.4%) patients who completed imaging; additional imaging was ordered for 38 patients (25.9%) and a second, unplanned surgery was performed for 14 (9.5%). CONCLUSION: The main predictive factor of ordering post-URS imaging was surgeons' time in practice and pre-operative hydronephrosis. Post-operative imaging changed management in 35.4% of patients. We recommend the development of guidelines encouraging routine imaging for patients following ureteroscopy.

Idiopathic bilateral ureteral stenosis presenting as bilateral hydronephrosis.

Ureteral stenosis is typically seen in the setting of genitourinary tract manipulation or nephrolithiasis. Bilateral idiopathic ureteral stenosis is an exceedingly rare clinical entity that has been described in only a small number of cases. More specifically, we describe a case of idiopathic bilateral, distal ureteral stenosis resulting in hydronephrosis and deterioration of renal function in an adolescent patient. The patient was successfully treated with robotic bilateral ureteral implants. This case brings to light a rare, but clinically relevant, cause of hydronephrosis, highlights the importance of early intervention in minimizing renal dysfunction, and describes a novel treatment option.

Rates of False-Negative Screening in Prostate Specific Antigen Secondary to 5-Alpha Reductase Inhibitor Usage: A Quality-Improvement Initiative

ABSTRACT Purpose Patients often take 5-alpha reductase inhibitors (5-ARIs) for the management of benign prostatic hyperplasia. However, 5-ARIs can decrease prostate specific antigen (PSA) by approximately half and therefore may lead to false negative PSA tests. We investigated false-screening rates in men on 5-ARIs undergoing PSA testing and whether ordering physicians noticed false negative findings. Materials and Methods A single institution, retrospective study was conducted on patients with a PSA value documented between 2014 and 2017. Patient demographics, PSA results, 5-ARI usage, and providing clinician characteristics were collected. Published normal PSA values were used to determine PSA test positivity; values for those on 5-ARIs were doubled. Results A total of 29,131 men were included. 1,654 (5.7%) were prescribed 5-ARIs at least 12 months prior to PSA evaluation. 118 men (7.1%) had a value that would be positive if corrected for 5-ARI usage, 33 (27.9%) of which had no indication that the provider had noted this. There was no effect on rates of false negative values if the PSA was ordered by a different provider than the one who prescribed the 5-ARI (p = 0.837). However, if the provider who ordered the PSA test was an urologist, the likelihood that a false negative value would be identified was lower (p=0.001). Conclusions More than a quarter of men with false negative tests were missed. This occurred more often when the ordering provider was not an urologist. An educational opportunity exists to improve the quality of PSA testing by preventing false negative tests.

Clinical Risk Factors Associated With Small Renal Mass Malignant Histology in a Multi-Ethnic Population Undergoing Partial Nephrectomy.

INTRODUCTION: Small renal masses (SRMs) are often incidentally diagnosed, and a large proportion are malignant. However, there is a paucity of data describing predictors of malignancy in minority patients with SRMs. Thus, our goal was to examine clinical risk factors associated with SRM malignant histology in patients undergoing partial nephrectomy (PN) a diverse, urban academic center. MATERIALS AND METHODS: Patients with a SRM undergoing PN at a single institution between 2010 to 2018 were reviewed. Demographic, clinical, and imaging characteristics were compared to pathology results. Logistic regression was used to examine associations between demographic/clinical variables for malignant and high-grade histology. RESULTS: In total, 331 patients who underwent PN for SRM were included. Of those, 264 (79.8%) had malignant histology while 67 (20.2%) had benign histology. The proportions of men and of current smokers were significantly higher among patients with malignant histology. In multivariate models, non-Hispanic Black (NHB) patients had increased odds of having malignant histology (OR 2.46, 95% CI: 1.01-5.99, P = .048) and current smokers (OR = 4.02; 95% CI 1.14-14.18, P = .031). Hispanic patients had a 3-fold increased risk of high-grade RCC (OR 3.06, 95% CI: 1.19-7.87, P = 0.02) compared to Non-Hispanic White patients. CONCLUSION: In our population, male sex, smoking, and NHB race/ethnicity was associated with an increased risk of malignancy in patients undergoing partial nephrectomy for SRM. Older age and Hispanic race/ethnicity were associated with high grade RCC. Our results suggest that urologists should exercise a higher level of vigilance in managing and treating SRM among NHB and Hispanic patients.

Association of Obesity and Diabetes With Prostate Cancer Risk Groups in a Multiethnic Population.

INTRODUCTION: Obesity and diabetes mellitus (DM) have been associated with prostate cancer (PCa) risk, but data examining their combined effects on aggressive PCa are sparse, particularly among non-Hispanic Black and Hispanic men. We investigated the associations of obesity and DM in relation to National Comprehensive Cancer Network (NCCN) PCa risk groups in a racially-diverse patient population. PATIENTS AND METHODS: We abstracted demographic and clinical data from men who underwent radical prostatectomy at our institution between 2005 and 2019. Patients were classified into three NCCN PCa risk-groups: low, intermediate and high-risk. Logistic regression models were used to examine the independent and combined associations of body mass index (BMI)/obesity and DM with risks of intermediate and high-risk PCa, adjusting for age and race/ethnicity. RESULTS: A total of 1303 men with PCa (average age 60 ± 6.9 years) were analyzed. The majority were non-Hispanic Black (N = 493, 38%) or Hispanic (N = 407, 31%). The prevalence of obesity (BMI ≥ 30 kg/m2) and DM was 29.3% (N = 382) and 28.3% (N = 369), respectively. In multivariate analyses, obesity was independently associated with an odds ratio (OR) = 2.21 of high-risk PCa (95% CI: 1.28-3.81), while DM was associated with an OR = 1.49 (95% CI: 1.05-2.11) of intermediate-risk PCa. Compared to non-obese men without diabetes, men with BMI ≥ 30 and DM had increased risks of both intermediate (OR = 1.93; 95% CI 1.12-3.43) and high-risk PCa (OR = 2.40; 95% CI 1.22-4.73). Interestingly, most of the association of high-risk PCa was driven by obesity. CONCLUSION: In this multiethnic population both obesity and DM were independently associated with intermediate- and high-risk PCa; however, most of the association for high-risk cancer was driven by obesity. Our results corroborate findings that obesity increases the risk of aggressive PCa; however, results regarding DM need to be confirmed in other large multiethnic populations.

National Trends and Prescription Patterns in Opiate Analgesia for Urolithiasis Presenting to Emergency Departments: Analysis of the National Hospital Ambulatory Medical Care Survey, 2006-2018.

OBJECTIVE: To analyze the National Hospital Ambulatory Medical Care Survey (NHAMCS) database to determine geographic and temporal trends, as well as variables associated with the likelihood of receiving an opioid prescription for urolithiasis in United States (US) emergency departments (EDs). MATERIALS AND METHODS: All ED visits for urolithiasis between 2006 and 2018 in the NHAMCS database were analyzed. Age, race/ethnicity, insurance status, ED provider credentials, geographic region, and urban vs rural hospital status were extracted. Linear regression was used to examine overall/regional trends in opioid prescriptions over time. Logistic regression was used to estimate factors associated with higher odds of receiving opioids. RESULTS: Fourteen million visits were analyzed, of which, 79.1% (11.0 million) received an opioid prescription. From 2014 to 2018 there was a decline of 3.65%/year of the proportion of visits receiving an opioid prescription (R2 = 0.86, P = .008). Non-Hispanic Black race was associated with a lower chance of receiving opioid prescription (OR = 0.57, P = .02) compared to Non-Hispanic Whites (NHW). Midwestern hospitals had higher odds of opioid prescription compared to the Northeast (OR = 2.05, P = .006). Rural hospitals had lower odds of opioid prescription compared to urban hospitals (OR = 0.62, P = .02). CONCLUSION: Opioid prescriptions for patients presenting with urolithiasis to the ED have steadily declined from 2014 to 2018, except in the Midwest. NHW race, Midwest region, and urban EDs increase the likelihood of receiving opioids. Continued efforts encouraging non-opioid alternatives for urolithiasis are essential, specifically in Midwestern EDs, to mitigate the ongoing opioid epidemic in the US.

The impact of surgical downgrading on prostate cancer recurrence: systematic review and analysis of a multiethnic population.

OBJECTIVE: To perform a systematic review and a retrospective cohort analysis evaluating the rates of surgical downgrading of prostate cancer (PCa) from biopsy (PBx) to radical prostatectomy (RP), and their association with biochemical recurrence (BCR) in a multiethnic population. METHODS: A systematic review of PubMed and other databases was performed. We included retrospective studies evaluating the relationship between surgical downgrading and BCR-free survival. Data regarding Gleason score (GL) downgrading were abstracted from the articles and categorized as follows: GL8-10 to GL7, GL7 to GL6, and GL 7(4 + 3) to GL7(3 + 4). We also performed a retrospective cohort review of patients who underwent RP at our institution from 2005 through 2020. Kaplan-Meier survival analysis and Cox proportional hazards models were used to compare BCR among downgraded versus non-downgraded men. RESULTS: Systematic review yielded 137 abstracts; of these, 36 full-texts were reviewed, 8 of which were included in our systematic review. Despite substantial variability, all showed that GL at RP is one of the most important factors of BCR-free survival. A total of 1,484 men with PCa were analyzed from our institution. On multivariate analysis, GL7 to GL6 downgrading (HR = 0.50, p = 0.022) and GL8-10 to GL7 downgrading (HR = 0.42, p = 0.011) were associated with reduced risk of BCR when compared to men with GL7 and GL8-10 concordance, respectively. However, GL7(4 + 3) to GL7(3 + 4) downgrading was not significantly associated with reduced BCR (HR = 0.56, p = 0.12), when compared to GL7(4 + 3) concordance, although HR was similar. CONCLUSION: Surgical downgrading at RP was associated with a reduced risk of BCR compared to GL concordant disease, and these findings have been validated within our multiethnic population. Pathologic downgrading at the time of RP may be a more useful predictor of subsequent BCR in comparison to that associated with GL concordant pathology.

Comparison of Patient Satisfaction and Safety Outcomes for Postoperative Telemedicine vs Face-to-Face Visits in Urology: Results of the Randomized Evaluation and Metrics Observing Telemedicine Efficacy (REMOTE) Trial.

INTRODUCTION: There is a need to better understand the role of postoperative care via telemedicine (TM). We evaluated patient satisfaction and outcomes of postoperative face-to-face (F2F) versus TM visits for adult ambulatory urological surgeries in an urban academic center. Methods:This was a prospective, randomized controlled trial. At surgery, patients undergoing ambulatory endoscopic procedures or open surgery were randomized 1:1 to a postoperative F2F or TM visit. After the visit, a telephone survey assessing satisfaction was administered. Primary outcome was patient satisfaction; secondary outcomes were time and cost savings, and 30-day safety outcomes. Results:A total of 197 patients were approached; 165 (83%) consented and were randomized-76 (45%) to F2F and 89 (54%) to TM cohorts. There were no significant differences in baseline demographics between the cohorts. Both cohorts were equally satisfied with their postoperative visit (F2F 98.6% vs TM 94.1%, p=0.28) and found their visit to be an acceptable form of health care (F2F 100% vs TM 92.7%, p=0.06). The TM cohort saved a significant amount of time (TM 66.2% spent <15 minutes vs F2F 43.1% spent 1-2 hours, p <0.0001) and money (44.1% TM saved $5-$25 vs 43.1% F2F spent $5-$25, p=0.041) associated with travel. There were no significant differences in 30-day safety outcomes between the cohorts. Conclusions:TM for postoperative visits after ambulatory adult urological surgery saves patients time and money without compromising satisfaction or safety. TM should be offered as an alternative to F2F for routine postoperative care for certain ambulatory urological surgeries.

Female Sexual Dysfunction as Measured by Low Sexual Frequency is Associated With Lower Socioeconomic Status: An Analysis of the National Health and Nutrition Examination Survey (NHANES), 2007-2016.

BACKGROUND: Female sexual dysfunction (FSD) is a complex disorder of biopsychosocial etiology, and FSD symptoms affect more than 40% of adult women worldwide. AIM: In this cross-sectional study, we sought to investigate the association between FSD and socioeconomic status (SES) in a nationally representative female adult population. METHODS: Economic and sexual data for women aged 20-59 from the 2007-2016 National Health and Nutrition Examination Survey, a United States nationwide representative database, was analyzed. Poverty income ratio (PIR), a ratio of family income to poverty threshold, was used as a measure of SES, and low sexual frequency was used as a measure of FSD. The association between FSD and SES was analyzed using survey-weighted logistic regression after adjusting for relevant social and gynecologic covariates, such as marital status and history of pregnancy, as well as significant medical comorbidities. OUTCOMES: We found that FSD, as measured by low sexual frequency, was associated with lower SES. RESULTS: Among the 7,348 women of mean age 38.4 (IQR 29-47) included in the final analysis, 26.3% of participants reported sexual frequency of 0-11 times/year and 73.7% participants reported sexual frequency >11 times/year. Participants of PIR <2 were 92% more likely to report sexual frequency ≤11 times/year than those of PIR ≥2 after adjusting for demographics, social history, gynecologic history and significant medical conditions (OR = 1.92; 95% CI = 1.21-3.05; P < .006). CLINICAL IMPLICATIONS: The evaluation and treatment of FSD may benefit from a comprehensive approach that takes SES into account. STRENGTHS & LIMITATIONS: This study is limited by its cross-sectional design, but it is strengthened by a large, nationally representative sample with extensive, standardized data ascertainment. CONCLUSION: Lower SES and lower sexual frequency are directly correlated among female adults in the United States; future studies should focus on social determinants of health as risk factors for FSD.

Acute asthma management with IV magnesium in obese, overweight and non-overweight inner-city children.

OBJECTIVE: IV Magnesium (IV Mg) is increasingly used as adjunctive therapy for asthma exacerbations. In obese patients, delays in recognition of asthma severity may lead to delays in IV Mg administration. Our objective was to examine whether timing of IV Mg administration varied by Body Mass Index (BMI) category and whether this relates to hospitalization course. METHODS: This is a retrospective chart review of IV Mg use for asthma in children 2-17 years of age hospitalized in an urban children's hospital. Weight status was categorized by BMI percentile for age. The primary outcome was time to IV Mg administration. Secondary outcomes included admission to the intensive care unit, time to discharge readiness and Length of Stay (LOS). Continuous variables were analyzed using Student's t-test or Mann-Whitney test, categorical variables with Chi-Square test or Fisher's exact test, as appropriate. A linear regression model examined factors related to time to IV Mg administration. RESULTS: In 2017, 361/698 (52%) of patients admitted with acute asthma received IV Mg. Of these, 210 patients met study criteria. Except for age, baseline characteristics did not vary by BMI category. No differences were found in Time to IV Mg, rates of admission to the intensive care unit, time to discharge readiness, or LOS comparing non-overweight to overweight or obese patients. CONCLUSIONS: In this sample of inner-city children who received IV Mg there were no differences in timing of IV Mg based on BMI category. Further work is needed to examine whether standardizing timing of IV Mg improves care.

Patient Satisfaction with Telephone Versus Video-Televisits: A Cross-Sectional Survey of an Urban, Multiethnic Population.

OBJECTIVE: To examine differences between telephone and video-televisits and identify whether visit modality is associated with satisfaction in an urban, academic general urology practice. METHODS: A cross sectional analysis of patients who completed a televisit at our urology practice (summer 2020) was performed. A Likert-based satisfaction telephone survey was offered to patients within 7 days of their televisit. Patient demographics, televisit modality (telephone vs video), and outcomes of the visit (eg follow-up visit scheduled, orders placed) were retrospectively abstracted from each chart and compared between the telephone and video cohorts. Multivariate regression analysis was used to evaluate variables associated with satisfaction while controlling for potential confounders. RESULTS: A total of 269 patients were analyzed. 73% (196/269) completed a telephone televisit. Compared to the video cohort, the telephone cohort was slightly older (mean 58.8 years vs. 54.2 years, P = .03). There were no significant differences in the frequency of orders placed for medication changes, labs, imaging, or for in-person follow-up visits within 30 days between cohorts. Survey results showed overall 84.7% patients were satisfied, and there was no significant difference between the telephone and video cohorts. Visit type was not associated with satisfaction on multivariable analyses, while use of an interpreter [OR:8.13 (1.00-65.94); P = .05], labs ordered [OR:2.74 (1.12-6.70); P = .03] and female patient gender [OR:2.28 (1.03-5.03); P = .04] were significantly associated with satisfaction. CONCLUSION: Overall, most patients were satisfied with their televisit. Additionally, telephone- and video-televisits were similar regarding patient opinions, patient characteristics, and visit outcome. Efforts to increase access and coverage of telehealth, particularly telephone-televisits, should continue past the COVID-19 pandemic.

Patient satisfaction and savings, and clinical outcomes of televisits in female pelvic medicine and reconstructive surgery at an urban academic center.

AIM: To evaluate patient satisfaction and savings, and compare visit outcomes based on chief complaint (CC) of women presenting for a televisit to a female pelvic medicine and reconstructive surgery (FPMRS) clinic at an urban academic center. METHODS: A cross-sectional study of women completing a televisit with an FPMRS specialist at our institution from June 19, 2020 to July 17, 2020 was conducted. A telephone questionnaire was administered to patients to assess satisfaction and savings (travel costs/time avoided). Electronic medical records were reviewed to collect patient demographics and comorbidities, CC, and televisit outcomes (e.g., face-to-face (F2F) exam scheduled, orders placed). Logistic regression was used to analyze predictors of satisfaction and need for F2F follow-up. RESULTS: One hundred eighty-seven of 290 (64.5%) women called completed the survey, of whom 168 (89.8%) were satisfied with their televisit. Eighty-eight (48.1%) saved at least an hour and 54 (28.9%) saved more than $25 on transportation. There were no significant associations between patient characteristics, CC, or televisit outcomes and satisfaction. Ninety-nine (52.9%) televisits resulted in F2F follow-up, with CC of prolapse (odds ratio [OR] = 4.2 (1.7-10.3); p = 0.002), new patient (OR = 2.2 (1.2-4.2); p = 0.01), and Hispanic ethnicity (OR = 3.9 (1.2-13.6); p=.03) as significant predictors. CONCLUSION: Most patients were satisfied with FPMRS televisits at our urban academic center. Televisits resulted in patient travel time and cost savings. Women presenting with prolapse and for new patient visits would likely benefit from initial F2F visits instead of televisits. Televisits are an important mode of health care and in some cases can replace F2F visits.

Intravesical Bacillus Calmette-Guérin Treatment Is Inversely Associated With the Risk of Developing Alzheimer Disease or Other Dementia Among Patients With Non-muscle-invasive Bladder Cancer.

BACKGROUND: The immune system plays an important role in the pathogenesis of Alzheimer disease (AD), but it remains unclear whether bacillus Calmette-Guérin (BCG) may affect the risk of AD or not. METHODS: Using retrospective chart review, we collected data regarding demographics, comorbidities, cancer diagnosis, BCG treatment, and subsequent diagnosis of AD or other dementia in a racially/ethnically diverse cohort of patients with non-muscle-invasive bladder cancer (NIMBC) receiving treatment between 1984 and 2020 in the Bronx, New York. We used Cox proportional hazard models to examine association between BCG treatment and risk of incident AD or other dementia, adjusting for age, gender, race/ethnicity, and major comorbidities. RESULTS: In our cohort of 1290 patients with NMIBC, a total of 99 (7.7%) patients developed AD or other dementia during follow-up. Patients who received BCG treatment (25%) had a 60% lowered incidence of AD or other dementia (adjusted hazard ratio [HR], 0.41; 95% confidence interval [CI], 0.21-0.80) in comparison to those who did not receive BCG. There was also suggestive evidence that the reduction in risk of AD or other dementia associated with BCG treatment was stronger in men (adjusted HR, 0.34; 95% CI, 0.15-0.81) but not in women (adjusted HR, 0.75; 95% CI 0.25-2.24). When we stratified the patients who received BCG by type of treatments, patients who received both induction and maintenance rounds of BCG had a further lowered incidence of AD or other dementia (HR, 0.23; 95% CI, 0.06-0.96) than patients who did not receive BCG. CONCLUSIONS: To our knowledge, our study is one of the first to suggest that BCG treatment is associated with a reduced risk of developing AD or other dementia in a multiethnic population, independent of significant comorbidities. Larger cohort studies are needed to corroborate our findings.

The relationship between vascular calcifications and urolithiasis in a large, multiethnic patient population.

Several studies have reported associations between vascular calcifications and urinary stone disease (USD). However, results have been inconsistent and the majority of studies did not report on race/ethnicity. We examined the association between vascular calcifications and USD in a large, racially/ethnically diverse patient population. We identified 672 USD cases and 672 controls (i.e., patients without a history of USD) from patients who underwent non-contrast CT imaging at Montefiore Medical Center in Bronx, New York between 2004 and 2013. Controls were matched to cases on age, sex and race/ethnicity. The non-contrast CT imaging was used to measure abdominal aortic calcification (AAC) and calculate the AAC severity score. Logistic regression models were used to examine associations of AAC presence and severity score with risks of USD and stone types. Cases and controls had similar AAC prevalence (45.2% vs. 44.8%, p = 0.87), and AAC severity score (median 10 vs. 9.3, p = 0.47). The presence of AAC (OR = 0.98, 95% CI 0.78-1.23; p = 0.86) or AAC severity score were not associated with risk of USD: ORs of 0.96, 0.87, 1.07 and 1.03 for increasing AAC quartiles (p-trend = 0.54). There were also no associations in the stratified analyses by race/ethnicity or by sex. However, when USD patients were stratified by stone type, brushite/apatite stone formers had an inverse association with the lowest quartile of AAC severity score (OR = 0.35, 95% CI 0.11-0.84, p = 0.04) in comparison to patients without AAC. Overall, we found no association between vascular calcifications and risk of urinary stone disease in this large, hospital-based, case-control study.

A Comparison of Image-Guided Targeted Prostate Biopsy Outcomes by PI-RADS® Score and Ethnicity in a Diverse, Multiethnic Population.

PURPOSE: NonHispanic Black (NHB) and Hispanic/Afro-Caribbean men have the highest risk of prostate cancer (PCa) compared to nonHispanic White (NHW) men. However, ethnicity-specific outcomes of targeted fusion biopsy (FB) for the detection of PCa are poorly characterized. We compared the outcomes of FB by Prostate Imaging Reporting and Data System (PI-RADS®) score and race/ethnicity among a diverse population. MATERIALS AND METHODS: We evaluated all men who underwent image-guided FB for suspicious lesions on prostate magnetic resonance imaging (≥PI-RADS 3) over a 2-year period. We examined associations of race/ethnicity and PI-RADS score with risk of PCa or clinically significant PCa (cs-PCa, Gleason Group ≥2) on FB using mixed-effects logistic regression models. RESULTS: A total of 410 men with 658 lesions were analyzed, with 201 (49.0%) identified as NHB and 125 (30.5%) identified as Hispanic. NHB men had a twofold increase in the odds of detecting cs-PCa (OR=2.7, p=0.045), while Hispanic men had similar odds of detecting cs-PCa compared to NHW men. With regard to all PCa, NHB men had a similar increase in the odds of detecting all PCa (OR=2.4, p=0.050), which was borderline statistically significant compared to NHW men on FB. When we excluded men on active surveillance, NHB men had even stronger associations with detection of cs-PCa (OR=3.10, p=0.047) or all PCa (OR=2.77, p=0.032) compared to NHW men. CONCLUSIONS: NHB men have higher odds for overall PCa and cs-PCa on FB compared to NHW men. Further work may clarify differences per PI-RADS score. Clinicians should interpret prostate magnetic resonance imaging lesions with more caution in NHB men.
