BACKGROUND Variation in PSA screening is a potential source of disparity in prostate cancer survival, particularly among underserved populations. We sought to examine the impact of race and socioeconomic status (SES) on receipt of PSA testing among low-income men. METHODS Black (n=22,167) and White (n=9,588) men age ≥40 completed a baseline questionnaire from 2002–2009 as part of the Southern Community Cohort Study. Men reported whether they had ever received PSA testing and had testing within the prior 12 months. To evaluate the associations between SES, race and receipt of PSA testing, odds ratios (ORs) and 95% confidence intervals (CIs) were estimated from the multivariable logistic models where age, household income, insurance status, marital status, body mass index, and educational level were adjusted. RESULTS Black men were younger, had a lower income, less attained education, and were more likely to be unmarried and uninsured (all p<0.001). Percentages of men having ever received PSA testing rose from <40% below age 45 to ~ 90% above age 65, with Whites >50 more likely than Blacks to have received testing. Lower SES was significantly associated with less receipt of PSA testing in both groups. After adjustment for SES, White men had significantly lower odds of PSA testing (OR 0.81, 95% CI 0.76–0.87). CONCLUSIONS Greater PSA testing among White than Black men over age 50 in this low income population appears to be mainly a consequence of SES. Strategies for PSA screening may benefit from tailoring to the social circumstances of the men being screened.
Background Systemic responses to cytoreductive nephrectomy (CN) in the management of metastatic renal cell carcinoma (mRCC) are variable and difficult to anticipate. The authors aimed to determine the association of CN with modifiable International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk factors and oncological outcomes. Methods Consecutive patients with mRCC referred for potential CN (2009‐2019) were reviewed. The primary outcome was overall survival (OS); variables of interest included undergoing CN and the baseline number of modifiable IMDC risk factors (anemia, hypercalcemia, neutrophilia, thrombocytosis, and reduced performance status). For operative cases, the authors evaluated the effects of IMDC risk factor dynamics, measured 6 weeks and 6 months after CN, on OS and postoperative treatment disposition. Results Of 245 treatment‐naive patients with mRCC referred for CN, 177 (72%) proceeded to surgery. The CN cases had fewer modifiable IMDC risk factors (P = .003), including none in 71 of 177 patients (40.1%); fewer metastases (P = .011); and higher proportions of clear cell histology (P = .012). In a multivariable analysis, surgical selection, number of IMDC risk factors, metastatic focality, and histology were associated with OS. Total risk factors changed for 53.8% and 57.2% of the patients from the preoperative period to 6 weeks and 6 months after CN, respectively. Adjusted for preoperative IMDC risk scores, an increase in IMDC risk factors at 6 weeks and 6 months was associated with adverse OS (hazard ratio [HR], 1.57; 95% confidence interval [CI], 1.13‐2.19; P = .007; HR, 2.52; 95% CI, 1.74‐3.65; P < .001). Conclusions IMDC risk factors are dynamic clinical variables that can improve after upfront CN in select patients, and this suggests a systemic benefit of cytoreduction, which may confer clinically meaningful prognostic implications.
Aim: Compare the circadian trajectory of diuresis between nocturnal polyuria (NP) patients with versus without identifiable contributory comorbidities. Methods: Retrospective analysis of frequency-volume charts from male patients with clinically-significant nocturia (≥2 nocturnal voids) and NP (defined by nocturnal urine production [NUP] ≥90 mL/hour or nocturnal polyuria index [NPi] ≥0.33). Patients with NP and chronic kidney disease, congestive heart failure, and/or undertreated obstructive sleep apnea (OSA) were deemed to have secondary NP. Nocturnal polyuria syndrome (NPS) was defined as NP without edema, loop diuretic use, or the aforementioned conditions. Patients with diabetes insipidus or OSA with appropriate continuous positive airway pressure utilization were excluded. The timing and volumes of nocturnal voids were used to derive "early" and "late" nocturnal diuresis rates (mL/hour of urine produced before and after the first nocturnal awakening, respectively). The likelihood of an early peak nocturnal diuresis rate (ie, early >late nocturnal diuresis rate) was compared between patients with NPS versus secondary NP using both a crude and adjusted odds ratio. Results: The likelihood of an early peak nocturnal diuresis rate in patients with NPS compared with secondary NP was 2.58 (1.05-6.31) at NUP ≥ 90 mL/hour and 1. 96 (0.87-4.42) at NPi ≥ 0.33 on crude analysis, and 2.44 (0.96-6.24) and 1.93 (0.83-4.48) after adjustment, respectively.Conclusions: A peak early nocturnal diuresis rate was significantly more likely in patients with NPS at NUP ≥ 90 mL/hour, with similar odds ratios at NPi ≥ 0.33 and following adjustment. Delineating nocturic patients by NP subgroup may facilitate more individualized management.
A critical analysis of the AUA symptom score using valid health literacy scales revealed that it is frequently not completed, requires prompting and takes longer to complete for men with low health literacy. The FLOW instrument represents a novel method to assess lower urinary tract symptoms in all men. It represents a valid alternative to the AUA symptom score.
