PrEP and Behavioral Health Treatment Referral Among HIV Test Counselors in Miami-Dade County: A Rapid Qualitative Study Using the Consolidated Framework for Implementation Research.

HIV test counselors are well positioned to refer individuals to pre-exposure prophylaxis (PrEP) and behavioral health treatments. HIV test counselors in Miami-Dade County (N = 20), a priority jurisdiction for Ending the HIV Epidemic, completed interviews to assess determinants of PrEP and behavioral health treatment referrals. To identify determinants, we used a rapid deductive qualitative analysis approach and the Consolidated Framework for Implementation Research (CFIR). Identified determinants sometimes served as facilitators (e.g., relative priority, leadership importance) and sometimes as barriers (e.g., lack of access to knowledge and information, available resources for referrals) to making referrals. We also observed differences in determinants between PrEP and behavioral health referrals. For example, complexity (perceived difficulty of the referral) was a barrier to behavioral health more often than PrEP referral. Our findings suggest that determinants across many CFIR domains affect referral implementation, and the corresponding need for multiple implementation strategies to improve implementation of PrEP and behavioral health referrals in the context of HIV testing.

Challenges and Opportunities with at-Home Blood Collection for HIV-1 Viral Load Monitoring among Sexual Minoritized Men who use Stimulants.

Sexually minoritized men (SMM) with HIV who use stimulants experience difficulties achieving and maintaining an undetectable viral load (VL). Home-based VL monitoring could augment HIV care by supporting interim, early identification of detectable VL. We describe implementation challenges associated with a home-collection device for laboratory-based VL testing among SMM with HIV who use stimulants. From March-May 2022, cisgender SMM with HIV reporting moderate-to-severe stimulant use disorder and suboptimal (< 90%) past-month antiretroviral therapy (ART) adherence were recruited via a consent-to-contact participant registry. Eligible men completed teleconference-based informed consent and were mailed a HemaSpot-HD blood collection device (volume capacity 160 µL; lower limit of detection 839 copies/mL) with detailed instructions for home blood self-collection and return shipment. Implementation process measures included estimated blood volume and VL quantification. Among 24 participants, 21 (88%) returned specimens with a median duration of 23 days (range: 10-71 days) between sending devices to participants and receiving specimens. Of these, 13/21 (62%) included enough blood (≥ 40 µL) for confidence in detectable/undetectable results; 10/13 (77%) had detectable VL, with 4/10 (40%) were quantifiable at ≥ 839 copies/mL. The remaining 8/21 had low blood volume (< 40 µL), but 3/8 (38%) still had detectable VL, with 1/3 (33%) quantifiable at ≥ 839 copies/mL. Home blood collection of ≥ 40 µL using HemaSpot-HD was feasible among this high-priority population, with > 50% having a VL detected. However, interim VL monitoring using HemaSpot-HD among those experiencing difficulties with ART adherence may be strengthened by building rapport via teleconferencing and providing detailed instructions to achieve adequate sample volume.

Disadvantaged groups have greater spatial access to pharmacies in New York state.

BACKGROUND: The accessibility of pharmacies has been associated with overall health and wellbeing. Past studies have suggested that low income and racial minority communities are underserved by pharmacies. However, the literature is inconsistent in finding links between area-level income or racial and ethnic composition and access to pharmacies. Here we aim to assess area-level spatial access to pharmacies across New York State (NYS), hypothesizing that Census Tracts with higher poverty rates and higher percentages of Black and Hispanic residents would have lower spatial access. METHODS: The population weighted mean shortest road network distance (PWMSD) to a pharmacy in 2018 was calculated for each Census Tract in NYS. This statistic was calculated from the shortest road network distance to a pharmacy from the centroid of each Census block within a tract, with the mean across census blocks weighted by the population of the census block. Cross-sectional analyses were conducted to assess links between Tract-level socio demographic characteristics and Tract-level PWMSD to a pharmacy. RESULTS: Overall the mean PWMSD to a pharmacy across Census tracts in NYS was 2.07 Km (SD = 3.35, median 0.85 Km). Shorter PWMSD to a pharmacy were associated with higher Tract-level % poverty, % Black/African American (AA) residents, and % Hispanic/Latino residents and with lower Tract-level % of residents with a college degree. Compared to tracts in the lowest quartile of % Black/AA residents, tracts in the highest quartile had a 70.7% (95% CI 68.3-72.9%) shorter PWMSD to a pharmacy. Similarly, tracts in the highest quartile of % poverty had a 61.3% (95% CI 58.0-64.4%) shorter PWMSD to a pharmacy than tracts in the lowest quartile. CONCLUSION: The analyses show that tracts in NYS with higher racial and ethnic minority populations and higher poverty rates have higher spatial access to pharmacies.

Comorbidity burden and health-related quality of life in men with advanced prostate cancer.

PURPOSE: Identifying clinically relevant comorbidities and their effect on health-related quality of life (HRQoL) outcomes among men with advanced prostate cancer (APC) can inform patient care and improve outcomes; however, this is poorly understood. The aim of this observational study was to examine the prevalence of comorbidities, and the relationship of comorbidity burden to HRQoL and other patient-reported outcomes (PROs) among men with APC. METHODS: Participants were 192 men (average age 68.8) with APC (stage III or IV) who completed a psychosocial battery including measures of sociodemographic factors, HRQoL and other PROs, and the Charlson Comorbidity Index (CCI). Hierarchical multiple regression analysis was used to examine the relationships between CCI, HRQOL, and PROs. RESULTS: The vast majority (82%) of participants had at least one comorbidity, with the most common being: hypertension (59%), connective tissue disease or arthritis (31%), diabetes (24%), and problems with kidneys, vision, or another organ (24%). After controlling for covariates, regressions showed that a higher CCI score was significantly associated with worse HRQoL (p < 0.001), lower levels of positive affect (p < 0.05), and higher levels of depression (p < 0.05), fatigue (p < 0.001), pain (p < 0.01), stress (p < 0.01), and cancer-specific distress (p < 0.05). CONCLUSIONS: Comorbidities were common among men with APC, and a greater CCI score was associated with detriments in several domains of HRQoL and other PROs. Our findings show the need to address comorbidities in the presence of a cancer diagnosis and subsequent treatment. TRIAL REGISTRATION CLINICALTRIALS. GOV IDENTIFIER: NCT03149185.

Factors associated with latino sexual minority men's likelihood and motivation for obtaining a COVID-19 vaccine: a mixed-methods study.

Minoritized communities are underreached by biomedical interventions, such as the COVID-19 vaccine. This mixed-methods study identified factors associated with vaccine likelihood (VL) and uptake (VU) among 187 Latino sexual minority men (LSMM) in South Florida. Regression models with LASSO variable selection and Classification and Regression Trees (CART) assessed determinants of VL and VU while open-ended questions were evaluated using thematic content analysis. VL (range 1-7; M = 6.00, SD = 1.84) and VU (63.6%) was high. LASSO modeling identified being insured, worrying about others, fear of transmitting COVID-19, and financial stress as the most influential factors for VL; working remotely from home was important for VU. Time (weeks) since addition of COVID-19 vaccination-related questions (December 2nd, 2020) was associated with both outcomes across both modeling techniques. Convergence between data suggests capitalizing on altruistic motivations and improving accessibility to vaccine campaigns are valuable assets to increase LSMM's vaccine confidence.

Structural Racism and Breast Cancer-specific Survival: Impact of Economic and Racial Residential Segregation.

OBJECTIVE: To analyze the effect of economic and racial/ethnic residential segregation on breast cancer-specific survival (BCSS) in South Florida, a diverse metropolitan area that mirrors the projected demographics of many United States regions. SUMMARY BACKGROUND DATA: Despite advances in diagnosis and treatment, racial and economic disparities in BCSS. This study evaluates these disparities through the lens of racial and economic residential segregation, which approximate the impact of structural racism. METHODS: Retrospective cohort study of stage I to IV breast cancer patients treated at our institution from 2005 to 2017. Our exposures include index of concentration at the extremes, a measurement of economic and racial neighborhood segregation, which was computed at the census-tract level using American Community Survey data. The primary outcome was BCSS. RESULTS: Random effects frailty models predicted that patients living in low-income neighborhoods had higher mortality compared to those living in high-income neighborhoods [hazard ratios (HR): 1.56, 95% confidence interval (CI): 1.23-2.00]. Patients living in low-income non-Hispanic Black and Hispanic neighborhoods had higher mortality compared to those living in high-income non-Hispanic White (NHW) neighborhoods (HR: 2.43, 95%CI: 1.72, 3.43) and (HR: 1.99, 95%CI: 1.39, 2.84), after controlling for patient characteristics, respectively. In adjusted race-stratified analysis, NHWs living in low-income non-Hispanic Black neighborhoods had higher mortality compared to NHWs living in high-income NHW neighborhoods (HR: 4.09, 95%CI: 2.34-7.06). CONCLUSIONS: Extreme racial/ethnic and economic segregation were associated with lower BCSS. We add novel insight regarding NHW and Hispanics to a growing body of literature that demonstrate how the ecological effects of structural racism-expressed through poverty and residential segregation-shape cancer survival.

Impact of COVID-19 on HIV service delivery in Miami-Dade County: a mixed methods study.

BACKGROUND: Facilitating access to HIV prevention and treatment is imperative in Miami-Dade County (MDC), a U.S. HIV epicenter. With COVID-19, disruptions to these services have occurred, leading HIV organizations to innovate and demonstrate resilience. This study documented COVID-19 related disruptions and resilient innovations in HIV services within MDC. METHODS: This mixed methods cross-sectional study included HIV test counselors in MDC. In the quantitative component (N=106), participants reported COVID-19 impacts on HIV service delivery. Data visualization examined patterns within organizations and throughout the study period. Generalized estimating equation modeling examined differences in service disruptions and innovations. In the qualitative component, participants (N=20) completed interviews regarding COVID-19 impacts on HIV services. Rapid qualitative analysis was employed to analyze interviews. RESULTS: Quantitative data showed that innovations generally matched or outpaced disruptions, demonstrating resilience on HIV service delivery during COVID-19. HIV testing (36%, 95%CI[28%, 46%]) and STI testing (42%, 95%CI[33%, 52%]) were most likely to be disrupted. Sexual/reproductive health (45%, 95%CI[35%, 55%]), HIV testing (57%, 95%CI[47%,66%]), HIV case management (51%, 95%CI[41%, 60%]), PrEP initiation (47%, 95%CI[37%,57%]), and STI testing (47%, 95%CI[37%, 57%]) were most likely to be innovated. Qualitative analysis revealed three orthogonal themes related to 1) disruptions (with five sub-components), 2) resilient innovations (with four sub-components), and 3) emerging and ongoing health disparities. CONCLUSIONS: HIV organizations faced service disruptions during COVID-19 while also meaningfully innovating. Our findings point to potential changes in policy and practice that could be maintained beyond the immediate impacts of COVID-19 to enhance the resilience of HIV services. Aligning with the US Ending the HIV Epidemic Plan and the National Strategy for HIV/AIDS, capitalizing on the observed innovations would facilitate improved HIV-related health services for people living in MDC and beyond.

Racial and Ethnic Disparities in Breast Cancer Survival: Emergence of a Clinically Distinct Hispanic Black Population.

OBJECTIVE: To understand the impact of Black race on breast cancer (BC) presentation, treatment, and survival among Hispanics. SUMMARY OF BACKGROUND DATA: It is well-documented that non-Hispanic Blacks (NHB) present with late-stage disease, are less likely to complete treatment, and have worse survival compared to their non-Hispanic White (NHW) counterparts. However, no data evaluates whether this disparity extends to Hispanic Blacks (HB) and Hispanic Whites (HW). Given our location in Miami, gateway to Latin America and the Caribbean, we have the diversity to evaluate BC outcomes in HB and HW. METHODS: Retrospective cohort study of stage I-IV BC patients treated at our institution from 2005-2017. Kaplan-Meier survival curves were generated and compared using the log-rank test. Multivariable survival models were computed using Cox proportional hazards regression. RESULTS: Race/ethnicity distribution of 5951 patients: 28% NHW, 51% HW, 3% HB, and 18% NHB. HB were more economically disadvantaged, had more aggressive disease, and less treatment compliant compared to HW. 5-year OS by race/ethnicity was: 85% NHW, 84.8% HW, 79.4% HB, and 72.7% NHB (P < 0.001). After adjusting for covariates, NHB was an independent predictor of worse OS [hazard ratio:1.25 (95% confidence interval: 1.01-1.52), P < 0.041)]. CONCLUSIONS: In this first comprehensive analysis of HB and HW, HB have worse OS compared to HW, suggesting that race/ethnicity is a complex variable acting as a proxy for tumor and host biology, as well as individual and neighborhood-level factors impacted by structural racism. This study identifies markers of vulnerability associated with Black race and markers of resiliency associated with Hispanic ethnicity to narrow a persistent BC survival gap.

Who Aren't We Reaching? Young Sexual Minority Men's Non-participation in an HIV-Prevention and Mental Health Clinical Trial.

Despite many successful clinical trials to test HIV-prevention interventions for sexual minority men (SMM), not all SMM are reached by these trials. Identifying factors associated with non-participation in these trials could help to ensure the benefits of research extend to all SMM. Prospective participants in New York City and Miami were screened to determine eligibility for a baseline assessment for a mental health/HIV-prevention trial (N = 633 eligible on screen). Logistic regression and classification and regression tree (CART) analysis identified predictors of non-participation in the baseline, among those who were screened as eligible and invited to participate. Individuals who reported unknown HIV status were more likely to be non-participators than those who reported being HIV-negative (OR = 2.39; 95% CI 1.41, 4.04). In New York City, Latinx SMM were more likely to be non-participators than non-Latinx white SMM (OR = 1.81; 95% CI, 1.09, 2.98). A CART model pruned two predictors of non-participation: knowledge of HIV status and age, such that SMM with unknown HIV status and SMM ages 18-19 were less likely to participate. Young SMM who did not know their HIV status, and thus are more likely to acquire and transmit HIV, were less likely to participate. Additionally, younger SMM (18-19 years) and Latinx SMM in New York City were less likely to participate. The findings suggest the importance of tailored recruitment to ensure HIV-prevention/mental health trials reach all SMM.

RESUMEN: A pesar de muchos ensayos clínicos exitosos para probar intervenciones de prevención del VIH para hombres de minorías sexuales (HMS), no todos los HMS son alcanzados por estos ensayos. La identificación de factores asociados con la no participación en estos ensayos podría ayudar a asegurar que los beneficios de la investigación se extiendan a todos los HMS. Se realizaron evaluaciones de teléfono para determinar la elegibilidad para la visita inicial para un ensayo de salud mental/prevención del VIH (N = 633 elegibles en las evaluaciones). La regresión logística y el análisis de arboles de regresión y clasificación (ARC) identificaron predictores de no participación en la visita inicial, entre aquellos que fueron evaluados como elegibles e invitados a participar. Los individuos que reportaron estado desconocido de VIH fueron más probables a ser no participantes que aquellos que reportaron ser VIH negativos (RP = 2.39; IC 95% 1.41, 4.04). En la ciudad de Nueva York, HMS latinx eran más probable a no participar que los HMS blancos no latinx (RP = 1.81; IC 95%, 1.09, 2.98). Un modelo de ARC podó dos predictores de no participación: el conocimiento del estado de VIH y la edad, tal que los HMS con estado desconocido del VIH y las HMS de 18­19 años eran menos probables a participar. Los HMS jóvenes que no conocían su estado de VIH, y por lo tanto eran más probables a adquirir y transmitir el VIH, tenían menos probabilidades de participar. Además, las HMS más jóvenes (18­19 años) y los HMS latinx en la ciudad de Nueva York eran menos probables a participar. Los resultados sugieren la importancia de un reclutamiento personalizado para garantizar que los ensayos de prevención del VIH y salud mental lleguen a todos los SMM.

Racial/Ethnic Disparities in the Incidence of Epithelial Ovarian Cancer in Florida by Histology, 2001-2015: Analysis of Trends.

OBJECTIVES: Because the population in Florida is 25.6% Hispanic, it is possible to evaluate the influence of race and ethnicity within clinically relevant subgroups of women with epithelial ovarian cancer (EOC), including histology and tumor grade. This study explores racial/ethnic disparities in the incidence of EOC in Florida by histology and tumor grade. METHODS: This study is an analysis of the Florida Cancer Database System. All incidence EOC cases from 2001 through 2015 were identified. Age-adjusted incidences were calculated and trends modeled by race/ethnicity and histology using Joinpoint and Poisson regression. RESULTS: In total, 80% of the 21,731 women with EOC were White, followed by Hispanic (13.1%) and non-Hispanic Black (7.9%). All races/ethnicities had statistically significant declines in incidence, with non-Hispanic White and non-Hispanic Black women having the steepest declines (annual percentage change -2.5, 95% confidence interval [CI] -5.9 to -2.1 and annual percentage change -2.8, 95% CI -4.8 to -1.5, respectively). A decreased incidence trend across the time period was seen for all subgroups (relative risk 0.97 [95% CI 0.96-0.98], 0.96 [95% CI 0.96-0.99], and 0.98 [95% CI 0.96-0.99] for non-Hispanic White, non-Hispanic Black, and Hispanic). High-grade EOC incidence for all groups did not change with time. CONCLUSIONS: We found significant declines in the incidence of EOC for all races/ethnicities, but not for high-grade EOC. The observed incidence decline in Hispanic women differs from previous research. More research is needed to understand women the causes of overall racial/ethnic differences and the decline in EOC.

Residential segregation and overall survival of women with epithelial ovarian cancer.

BACKGROUND: To the authors' knowledge, the etiology of survival disparities in patients with epithelial ovarian cancer (EOC) is not fully understood. Residential segregation, both economic and racial, remains a problem within the United States. The objective of the current study was to analyze the effect of residential segregation as measured by the Index of Concentration at the Extremes (ICE) on EOC survival in Florida by race and/or ethnicity. METHODS: All malignant EOC cases were identified from 2001 through 2015 using the Florida Cancer Data System (FCDS). Census-defined places were used as proxies for neighborhoods. Using 5-year estimates from the American Community Survey, 5 ICE variables were computed: economic (high vs low), race and/or ethnicity (non-Hispanic white [NHW] vs non-Hispanic black [NHB] and NHW vs Hispanic), and racialized economic segregation (low-income NHB vs high-income NHW and low-income Hispanic vs high-income NHW). Random effects frailty models were conducted. RESULTS: A total of 16,431 malignant EOC cases were diagnosed in Florida among women living in an assigned census-defined place within the time period. The authors found that economic and racialized economic residential segregations influenced EOC survival more than race and/or ethnic segregation alone in both NHB and Hispanic women. NHB women continued to have an increased hazard of death compared with NHW women after controlling for multiple covariates, whereas Hispanic women were found to have either a similar or decreased hazard of death compared with NHW women in multivariable Cox models. CONCLUSIONS: The results of the current study indicated that racial and economic residential segregation influences survival among patients with EOC. Research is needed to develop more robust segregation measures that capture the complexities of neighborhoods to fully understand the survival disparities in EOC.

Racial and ethnic disparities in the overall survival of women with epithelial ovarian cancer in Florida, 2001-2015.

Many studies have focused on white and black disparities in epithelial ovarian cancer (EOC) but fewer include Hispanics. Florida presents a unique opportunity to study racial/ethnic disparities. This study examined racial/ethnic disparities in the overall survival of women with EOC in Florida by histology. All EOC cases from 2001 through 2015 were identified in the Florida Cancer Database System (FCDS). Survival curves by race/ethnicity and histology were generated by Kaplan-Meier methods. Cox regression evaluated the associations between race/ethnicity, histology, and survival. Eligible EOC cases (n = 21,721) identified in the 2001-2015 FCDS were included in the study. The median survival for non-Hispanic whites (NHWs), non-Hispanic blacks (NHBs), and Hispanics was 31, 21, and 35 months, respectively (p < 0.001). NHB had an increased [AHR 1.23 (95% CI 1.15, 1.30)] and Hispanics a nonsignificant decreased hazard [AHR 0.96 (95% CI 0.91, 1.02)] of death compared to NHW after controlling for other demographic, treatment, and tumor characteristics. Relative to NHWs, NBH had worse survival while Hispanics had equivalent survival. Future research should consider evaluating genetic and epigenetic modifications, and prevalence of cancer syndromes to further elucidate the etiologies of disease in these disparate populations.

SCAN360: A Resource for a 360-Degree View of Cancer Prevention, Risk, and Survival.

SCAN360, an interactive web platform aiming to provide a "360-degree view" of factors that drive cancer, calculates and integrates several measures of cancer burden from the Florida Cancer Data System, the state's cancer registry, from 2012 to 2016 with cancer risk factors, clinical factors, and social determinants of health on multiple levels of geography - ranging from the entire state to the neighborhood. Integrating various sources of data, the web platform visualizes numerous indicators, including sociodemographic characteristics, cancer histology and staging, risk behaviors, screening behavior, environmental factors, hazardous sites, health insurance access, prevalence of potential comorbidities, housing characteristics, and levels of residential segregation, through maps and easy-to-interpret graphs. By walking through an example of a practical use, we show that SCAN360 provides data that are easily accessible to public health professionals, decision makers, and researchers and can assist them with identifying potential drivers of cancer burden on a localized level.

Combined General and Epidural Anesthesia is Associated With Decreased Opioid Consumption and Enhanced Pain Control After Penile Inversion Vaginoplasty in Transwomen.

BACKGROUND: Penile skin inversion vaginoplasty is a gender-affirming surgical procedure for transwomen with limited surgical analgesic protocol. This study compares the postoperative pain and opioid use in patients managed for surgery with general anesthesia (GA) with patients who were given combined epidural and general anesthesia (E/GA) with continuing postoperative epidural analgesia. METHODS: All patients who underwent penile inversion vaginoplasty between May of 2016 and May of 2018 under the care of single surgeon were identified retrospectively, 18 patients of which met the inclusion criteria. A retrospective chart review was conducted. Outcome measures were postoperative pain using visual analog scale, type and dosage of postoperatively administered intravenous or oral opioids (converted to morphine milligram equivalents, duration of inpatient admission, and time to ambulation. RESULTS: Patients who received combined E/GA reported significantly less pain and used less opioids during the first 4 postoperative days in comparison with patients who received GA alone. The reduction in mean pain associated with the use of an epidural was found to be statistically significant (P < 0.0005) as was the difference in opioid used in the 2 groups (P < 0.005) over the first 4 days postoperatively. Differences in day 5 pain suggest that postoperative pain is significantly lower even after the epidural has been removed (P < 0.005). There was no significant difference in length of hospital stay and time to ambulation (P > 0.05). CONCLUSIONS: Combined E/GA was associated with decreased inpatient opioid consumption after surgery and provided superior pain control than administration of GA alone. Based on these findings, combined E/GA should be strongly considered for patients undergoing penile inversion vaginoplasty.

Obstacles to successful treatment of hepatitis C in uninsured patients from a minority population.

BACKGROUND: Hepatitis C virus (HCV) treatment regimens (DAAs) are well tolerated, efficacious but costly. Their high cost and restricted availability, raises concerns about the outcome of treatment in uninsured patients. This study investigated sustained virologic response (SVR) outcomes in a predominately uninsured patient population and completion of four steps along the HCV treatment cascade. METHODS: A retrospective chart review was conducted to characterize the patient population and analyze covariates to determine association with insurance status, attainment of SVR and progression through the HCV treatment cascade. RESULTS: Out of a total of 216 patients, 154 (71%) were uninsured. Approximately 50% of patients (109 of 216 patients) were male and 57% were Hispanic (123 of 216 patients). Sex, race, ethnicity, treatment compliance, and rates of complications were not associated with insurance status. Insured patients were older (median 60 years vs 57 years, p-value < 0.001) and had higher rates of cirrhosis: 32 out of 62 patients (52%) vs 48 out of 154 patients (31%) (p-value = 0.005). Insured patients were tested for SVR at similar rates as uninsured patients: 84% (52 of 62 patients) vs 81% (125 of 154 patients), respectively. Of those tested for SVR, the cure rate for insured patients was 98% (51 out of 52 patients) compared to 97% (121 out of 125 patients) in the uninsured. Out of those who completed treatment, 177 of 189 (94%) were tested for attainment of SVR. Compliance rates were significantly different between tested and untested patients: 88% (156 of 177 patients) vs 0% (0 of 12 patients), respectively (p-value < 0.001). However, insurance status, race ethnicity, cirrhosis, and complications were not associated with being tested for SVR. CONCLUSIONS: These results demonstrate that insured and uninsured patients with chronic HCV infection, with access to patient assistance programs, can be treated and have comparable clinical outcomes. In addition, testing for SVR remains an important obstacle in completion of the HCV treatment cascade. Nevertheless, patient assistance programs remove a significant barrier for treatment access in real-world HCV infected populations.

The Impact of Immediate Salvage Surgery on Corporeal Length Preservation in Patients Presenting with Penile Implant Infections.

PURPOSE: Removal of an infected penile implant often results in corporeal fibrosis, irreversible penile shortening and dissatisfaction with future implant surgery. Salvage surgery may avoid these problems but to our knowledge no study to date has evaluated these specific end points. We evaluated patients who presented to our center with an infected implant to determine the impact of salvage surgery on penile length. MATERIALS AND METHODS: We evaluated consecutive patients undergoing removal of an infected penile prosthesis with immediate salvage or delayed reimplantation using a comprehensive, prospective database. Total corporeal length prior to and following immediate salvage or delayed reimplantation were compared. The impact of patient age, comorbidities, bacterial species, initial penile length and time to reimplantation on subsequent total corporeal length was evaluated. RESULTS: The cohort consisted of 40 patients. Overall 81% of salvaged cases were successful, resulting in a mean 0.6 cm (95% CI 0.20 to 1.1) reduction in total corporeal length. Delayed reimplantation resulted in a mean 3.7 cm (95% CI 2.9-4.5) total corporeal length loss. In patients who underwent delayed reimplantation the total corporeal length reduction was directly proportionate to the initial penis size of the patient. No statistically significant impact on penile length was attributable to patient age, diabetes, bacterial species or time to reimplantation. CONCLUSIONS: When possible, salvage surgery should be offered to patients with an infected penile implant. Our data confirmed that successful salvage surgery preserves penile length. When a device is explanted and replaced at a later date, patients can expect to lose 15% to 30% of penile length irrespective of age, diabetes, type of infecting organism and time to reimplantation.

Propensity matched comparative analysis of survival following chemoradiation or radical cystectomy for muscle-invasive bladder cancer.

OBJECTIVE: To compare survival outcome between chemoradiation therapy (CRT) and radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS: We conducted a retrospective analysis of patients with MIBC (≥cT2, N0, M0) in the National Cancer Database (2004-2013). CRT was defined as a radiation dose of ≥40 Gy and chemotherapy within 90 days of radiation. Descriptive statistics were used to compare groups. RC and CRT patients were propensity matched. Kaplan-Meier analysis was used to compare overall survival (OS). Multivariable Cox regression was used to determine predictors of survival. RESULTS: In all, 8 379 (6 606 RC and 1 773 CRT) patients met the inclusion criteria and 1 683 patients in each group were propensity matched. On multivariable extended Cox analysis, significant predictors of decreased OS were age, Charlson-Deyo Comorbidity score of 1, Charlson-Deyo Comorbidity score of 2, stage cT3-4, and urothelial histology. CRT was associated with decreased mortality at year 1 (hazard ratio [HR] 0.84, 95% confidence interval [CI] 0.74-0.96; P = 0.01), but at 2 years (HR 1.4, 95% CI 1.2-1.6; P < 0.001) and 3 years onward (HR 1.5, 95% CI 1.2-1.8; P < 0.001) CRT was associated with increased mortality. The 5-year OS was greater for RC than for CRT (38% vs 30%, P = 0.004). CONCLUSIONS: Initially after treatment for MIBC the risk of mortality is lower with CRT compared to RC. However, at ≥2 years after treatment the mortality risk favours RC. Patients who are suitable surgical candidates, with a low risk of morbidity, may be better served by RC.

Racial disparity and survival outcomes between African-American and Caucasian American men with penile cancer.

OBJECTIVE: To determine whether there is a survival difference for African-American men (AAM) versus Caucasian American men (CM) with penile squamous cell carcinoma (pSCC), particularly in locally advanced and metastatic cases where disease mortality is highest. PATIENTS AND METHODS: Using the Florida Cancer Data System, we identified men with pSCC from 2005 to 2013. We compared age, follow-up, stage, race, and treatment type between AAM and CM. We performed Kaplan-Meier analysis for overall survival (OS) between AAM and CM for all stages, and for those with locally advanced and metastatic disease. A multivariable model was developed to determine significant predictors of OS. RESULTS: In all, 653 men (94 AAM and 559 CM) had pSCC and 198 (30%) had locally advanced and/or metastatic disease. A higher proportion of AAM had locally advanced and/or metastatic disease compared to CM (38 [40%] vs 160 [29%], P = 0.03). The median (interquartile range) follow-up for the entire cohort was 12.6 (5.4-32.0) months. For all stages, AAM had a significantly lower median OS compared to CM (26 vs 36 months, P = 0.03). For locally advanced and metastatic disease, there was a consistent trend toward disparity in median OS between AAM and CM (17 vs 22 months, P = 0.06). After adjusting for age, stage, grade, and treatment type, AAM with pSCC had a greater likelihood of death compared to CM (hazard ratio 1.64, P = 0.014). CONCLUSIONS: AAM have worse OS compared to CM with pSCC and this may partly be due to advanced stage at presentation. Treatment disparity may also contribute to lessened survival in AAM, but we were unable to demonstrate a significant difference in treatment utilisation between the groups.

Perioperative outcomes and complication predictors associated with open and minimally invasive nephroureterectomy.

INTRODUCTION: Minimally invasive nephroureterectomy (MINU) and open nephroureterectomy (ONU) have similar oncological outcomes for treatment of upper tract urothelial carcinoma (UTUC). We investigated perioperative outcomes and predictors of complications associated with MINU and ONU. MATERIAL AND METHODS: Using the National Surgical Quality Improvement Program (NSQIP) database, 912 patients were identified that underwent radical nephroureterectomy for UTUC between 2005 and 2013. Logistic regression and contingency table methods used preoperative covariates to predict rates of major (Clavien-Dindo grade ≥ 3) and 16 common perioperative complications. Additional comparisons between treatment groups were performed using unpaired t-tests, Wilcoxon rank-sum tests, or Fisher's Exact tests. P values were adjusted to maintain an experiment-wise p < 0.05. RESULTS: A total of 625 (69%) and 287 (31%) patients underwent MINU and ONU, respectively. ONU was associated with a higher rate of major complications (OR: 2.5, CI: 1.2-5.1, p < 0.03). The incidence of pulmonary embolism (bias adjusted OR: 24, CI: 1.3-441, p < 0.003), postoperative pneumonia (OR: 4.9, CI: 1.7-16, p < 0.0016), and transfusion (OR: 2.7, CI: 1.8-4.0, p < 0.0001) was higher for ONU compared to MINU. There were no significant differences in the incidence of other complications. MINU took longer on average (median 223 versus 213 mins, p < 0.02). Time to discharge was longer for ONU (median 5 versus 4 days, p < 0.0001). No other covariates were independent predictors of major complications regardless of surgical approach. CONCLUSIONS: Occurrence of major complications were higher for ONU compared to MINU. These data suggest that MINU is an acceptable surgical option with lower morbidity compared to ONU for the management of UTUC.

Variation in type II endometrial cancer risk by Hispanic subpopulation: An exploratory analysis.

BACKGROUND: Minorities have demonstrated an increased risk for type II endometrial cancers, but no data exists about risk among minority subpopulations. Our objective was to evaluate heterogeneity in risk of type II endometrial cancer (EC) histologies across race and Hispanic sub-groups using data from Florida's statewide cancer registry (FCDS). METHODS: FCDS contains data on N=26,416 women diagnosed with EC from 2004 to 2013. Our analysis included women ≥18years of age who were classified as non-Hispanic White (NHW), non-Hispanic Black (NHB) or belonged to one of five Hispanic sub-groups, and had a histology code consistent with type I or type II EC. Binary logistic regression analyses were performed to model risk of type II versus type I ECs across racial and ethnic groups relative to NHW. RESULTS: Relative to NHW, overall odds of being diagnosed with a type II EC were significantly higher in NHB (OR=2.64, 95%CI: 2.38-2.92), Cubans (OR=1.35, 95%CI: 1.08-1.68) and South and Central Americans (SCA) (OR=1.84, 95%CI: 1.40-2.43). Compared to NHW, odds of serous EC were significantly higher in Cubans (OR=2.15, 95% CI: 1.51-3.05) and NHB (OR=2.51, 95% CI: 2.11-2.97); odds of carcinosarcoma (CS) were significantly higher in NHB (OR=2.97, 95% CI: 2.47-3.57) and Puerto Ricans (OR=2.35, 95%CI: 1.32-4.17); and odds of grade III adenocarcinoma (AG3) were significantly higher in NHB (OR=1.60, 95% CI: 1.42-1.81) and SCA (OR=1.76, 95%CI: 1.29-2.40). CONCLUSION: Risk of type II EC varies considerably across Hispanic sub-groups, with Cubans, Puerto Ricans and SCA characterized by elevated odds for specific type II histologies.
