INTRODUCTION: Though LUTS and sleep problems often co-occur, whether sleep disturbances are linked with LUTS development and progression is unknown. We examined the relationship between sleep problems measured by the Medical Outcomes Study Sleep Scale (MOS-Sleep) 6-item survey and LUTS development and progression in the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) study. METHODS: REDUCE was a randomized trial testing prostate cancer chemoprevention with dustasteride in men with PSA 2...

Background: The ERSPC (European Randomized Study of Screening for Prostate Cancer) found that screening reduced prostate cancer mortality, but the PLCO (Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial) found no reduction. Objective: To evaluate whether effects of screening on prostate cancer mortality relative to no screening differed between the ERSPC and PLCO. Design: Cox regression of prostate cancer death in each trial group, adjusted for age and trial...

PURPOSE: Mentored K (K01/K08/K23) career development awards are positively associated with physicians' success as independent investigators; however, individuals in some racial/ethnic groups are less likely to receive this federal funding. The authors sought to identify variables that explain (mediate) the association between race/ethnicity and mentored K award receipt among U.S. LCME-accredited medical school graduates who planned research-related careers. METHOD: The authors analyzed deidentified data from the Association of American Medical Colleges and the National Institutes of Health Information for Management, Planning, Analysis, and Coordination II grants database for a national cohort of 28,690 graduates from 1997-2004 who planned research-related careers, followed through August 2014...

BACKGROUND: We previously found no significant differences in mortality between men who underwent surgery for localized prostate cancer and those who were treated with observation only. Uncertainty persists regarding nonfatal health outcomes and long-term mortality. METHODS: From November 1994 through January 2002, we randomly assigned 731 men with localized prostate cancer to radical prostatectomy or observation. We extended follow-up through August 2014 for our primary outcome, all-cause mortality, and the main secondary outcome, prostate-cancer mortality...

Chronic pain is often measured with a severity score that overlooks its spatial distribution across the body. This widespread pain is thought to be a marker of centralization, a central nervous system process that decouples pain perception from nociceptive input. Here, we investigated whether centralization is manifested at the level of the brain using data from 1079 participants in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network (MAPP) study. Participants with a clinical diagnosis of urological chronic pelvic pain syndrome (UCPPS) were compared to pain-free controls and fibromyalgia patients, the prototypical centralized pain disorder...

BACKGROUND: To evaluate whether the presence of both prostate atrophy (PA) and chronic prostate inflammation (CPI) in the same biopsy and in the same biopsy core are associated with prostate cancer (PCa) risk and grade in repeat biopsies. METHODS: Retrospective analyses of 6132 men who were 50-75 years old undergoing 2-year repeat prostate biopsy after a negative baseline biopsy for PCa in the REduction by DUtasteride of prostate Cancer Events (REDUCE) study. PA, CPI and PCa were determined by central pathology...

Do summer laboratory research apprenticeships during high school have an impact on entry into MD/PhD programs? Apart from the nearly decade-long span of time between high school and matriculation into an MD/PhD program, young people have many life-shaping experiences that presumably impact their education and career trajectories. This quantitative study (n = 236,432) examines the connection between early laboratory research apprenticeship experiences at the high school level and matriculation into one of the more rigorous educational programs for scientific research training...

Statin use is associated with lower advanced prostate cancer risk. In addition to cholesterol lowering, statins have systemic anti-inflammatory properties. However, their effect on histologic prostate inflammation is not well understood, particularly among men at increased prostate cancer risk but with a negative prostate biopsy. We examined associations between serum lipid levels, statin use, and histologic prostate inflammation using data from 6,655 men with a negative baseline prostate biopsy in the REduction by DUtasteride of prostate Cancer Events (REDUCE) trial...

Diffusion imaging is critical for detecting acute brain injury. However, normal apparent diffusion coefficient (ADC) maps change rapidly in early childhood, making abnormality detection difficult. In this article, we explored clinical PACS and electronic healthcare records (EHR) to create age-specific ADC atlases for clinical radiology reference. Using the EHR and three rounds of multiexpert reviews, we found ADC maps from 201 children 0-6 years of age scanned between 2006 and 2013 who had brain MRIs with no reported abnormalities and normal clinical evaluations 2+ years later...

BACKGROUND: Prostate-specific antigen (PSA) hemodilution is the leading theory for lower PSA values in obese men. However, testosterone and dihydrotestosterone (DHT), which are necessary for PSA production, are reduced in obese men. We assessed the relationship of body mass index (BMI) and PSA, taking into consideration the effect of testosterone and DHT. METHODS: Among 8,122 participants in Reduction by Dutasteride of Prostate Cancer Events (REDUCE), complete data were available for 7,275...

OBJECTIVE: To determine the added value of prostate magnetic resonance imaging (MRI) to the Prostate Cancer Prevention Trial risk calculator. METHODS: Between January 2012 and December 2015, 339 patients underwent prostate MRI prior to biopsy at our institution. MRI was considered positive if there was at least 1 Prostate Imaging Reporting and Data System 4 or 5 MRI suspicious region. Logistic regression was used to develop 2 models: biopsy outcome as a function of the (1) Prostate Cancer Prevention Trial risk calculator alone and (2) combined with MRI findings...
