Abstract
Abstract
Introduction: Obesity and type II diabetes mellitus (T2DM) have been associated with adverse prostate cancer (PrCa) outcomes in several studies; however, results have been inconsistent. We examined the independent and combined effects of body mass index (BMI)/obesity and T2DM in relation to the National Comprehensive Cancer Network (NCCN) PrCa risk groups in a large, racially-diverse patient population from an urban medical center. Methods: We abstracted demographic, clinical and pathological data, as well as BMI/obesity and T2DM status at time of PrCa diagnosis from all patients, who underwent radical prostatectomy for their cancer at our academic institution from 2005 through 2019. Patients were classified into three NCCN PCa risk groups: low, intermediate and high risk based on their pathological Gleason score, tumor stage and diagnostic serum PSA. Multinomial logistic regression models were used to examine associations of obesity (BMI>30kg/m2) and T2DM with risks of intermediate and high risk PCa (comparison group were men with low risk disease). We examined both independent and combined effects of obesity and T2DM in multivariate models adjusted for age and race/ethnicity (main effect models were also adjusted for BMI or T2DM). Results: A total 1,366 PrCa patients with an average age of 60±6.9 years old with complete data were included in this analysis. The majority of patients were African-American (37.2%) or Hispanic (31.5%). The prevalence of obesity and T2DM were 29.4% and 28% respectively in this cohort, with African-Americans having the highest prevalence of both obesity (38.1%) and T2DM (43.6%) compared to other races/ethnicities. A large proportion of patients had NCCN intermediate (64%) or high-risk (14%) disease. In multivariate analyses, obesity was associated with 2.23 increased odds of high-risk PCa (95%CI: 1.26-3.93), while T2DM was associated with OR=1.53 (95%CI: 1.08-2.17) of intermediate risk PCa. Interaction analysis showed that obese patients with T2DM had increased risks of both intermediate (OR=1.99; 95%CI 1.16-3.41) and high-risk PCa (OR=2.28; 95%CI 1.14-4.53) when compared to lean men without T2DM.
Discussion: In this multiracial population, both obesity and T2DM were independently associated with high risk PrCa. Moreover, there was an additive effect of obesity and T2DM in the odds of developing both intermediate and high risk PrCa. Potential biological pathways of insulin signaling and inflammatory factors arising from adipokines could be involved in promoting more aggressive PrCa phenotypes. Larger cohort studies are needed to better elucidate the mechanisms between T2DM, obesity, and PrCa tumor pathology.

Abstract
PURPOSE Increased adrenergic innervation is observed in prostate cancer (CaP) and is associated with aggressive disease. Emerging evidence suggests that beta-adrenergic blockade inhibits CaP progression. However, the association between type of beta-blocker use and risk of incident CaP on initial prostate biopsy has not been investigated in multiethnic populations. MATERIALS AND METHODS A retrospective study of racially/ethnically diverse men (64% African-American and Hispanic), who underwent initial prostate biopsy between 2006 and 2016 in a large healthcare system was performed. Oral use of beta-blocker type was assessed by reviewing active prescriptions within the 5-year period preceding initial biopsy. Patient demographics and clinical factors were collected. RESULTS Of 4,607 men who underwent initial prostate biopsy, 4,516 met criteria and 2,128 had a biopsy positive for CaP; 20% high-risk, 41% intermediate-risk, and 39% low or very-low risk (National Comprehensive Cancer Network classification). Overall, 15% of patients were taking a beta-blocker prior to initial biopsy, with Metoprolol, Atenolol, and Carvedilol accounting for the majority. Of beta-blocker types, Atenolol alone was associated with a 38% reduction in odds of incident CaP (P= 0.01), with a 40% and 54% reduction in risks of National Comprehensive Cancer Network intermediate and high-risk CaP (P = 0.03 and P = 0.03, respectively) compared to men not taking a beta-blocker. Furthermore, longer duration of Atenolol use (3-5 years) was associated with a 54% and 72% reduction in intermediate and high-risk disease, (P = 0.03 and P = 0.03, respectively). CONCLUSIONS Among beta blocker types, long-term Atenolol use is associated with a significant reduction in incident CaP risk on initial prostate biopsy for clinically-significant intermediate and high-risk disease compared to men not taking a beta-blocker.

Abstract
OBJECTIVE To evaluate adherence to the American Urologic Association (AUA) best practice statement guidelines regarding antibiotic duration in the perioperative setting for endoscopic urologic surgery. We assessed concordance to these guidelines among adult urologists at a single academic institution and its correlation with postoperative positive urine cultures as it relates to the revised 2019 best practice statement. METHODS We performed a retrospective review of all adult endoscopic ambulatory urologic surgeries performed over an 18-month period by urologists at our institution. Patient demographics, pre- and postoperative urine cultures, operative details, stent or foley use, and antibiotic prescriptions were reviewed. Chi-squared and linear regression analyses were done. RESULTS Three hundred thirty patients were included for analysis. Sixty-two percent of patients were prescribed postoperative antibiotics, for an average of 4 days. Trimethoprim/Sulfamethoxazole and fluroquinolones were most often prescribed (43% and 38%, respectively). Intraoperative stent placement, positive urine culture within 30 days prior to surgery, and a positive urine culture within 1 year prior to surgery predicted antibiotic prescription. No significant differences were seen in rates of positive postoperative urine culture rates between cohorts that received antibiotics postoperatively vs those who did not. CONCLUSIONS At our academic institution, we observed poor concordance with the AUA best practice statement for perioperative antibiotic prescription after ambulatory endoscopic urologic surgery. Rates of positive postoperative cultures were low and not associated with receipt or duration of antibiotic prescription at the time of surgery, supporting minimal use of antibiotics for most endoscopic cases.

Abstract
OBJECTIVE To investigate if using a novel treatment for obstructive benign prostatic hyperplasia (UroLift) to relive lower urinary tract symptoms (LUTS) prior to external beam radiotherapy (EBRT) could also supplant the use of fiducial markers obviating the need for a second transrectal procedure while facilitating symptom-free voiding during and after EBRT a series of patients are reported on. METHODS The medical records of 7 consecutive patients who underwent placement of UroLift for simultaneous treatment of obstructive LUTS due to benign prostatic hyperplasia and targeting of EBRT for treatment of prostate cancer between September and December of 2015 were reviewed. RESULTS The UroLift clips were sufficiently radiopaque to make targeting possible for EBRT. All patients were able to complete a full course of radiotherapy without placement of fiducial markers. No patient experienced complications that could be attributed to the UroLift implants or procedure during their course of radiotherapy. None of the patients required additional alpha-blockers during radiation therapy. CONCLUSION The UroLift system can serve as fiducial markers in patients undergoing EBRT. Although the current clip utilized in the UroLift system is generally radiopaque, it does not project well on the sagittal plane and would be significantly enhanced if a more strongly opaque substance was incorporated. It remains to be proven if the UroLift system can significantly reduce the symptoms of LUTS during and post EBRT.

Abstract
OBJECTIVE To identify current distracted driving (DD) behaviors among college students, primarily those involving cell phone use, and elucidate the opinions of the students on the most effective deterrent or intervention for reducing cell phone use. METHODS Students enrolled at 12 colleges and universities were recruited to participate in an online, anonymous survey. Recruitment was done via school-based list-serves and posters. School sizes ranged from 476 to over 30,000. The validated survey included 38 questions; 17 were specifically related to distracted driving. RESULTS Four thousand nine hundred sixty-four participants completed the surveys; the average age was 21.8, 66% were female, 82.7% were undergraduates, and 47% were white/non-Hispanic. Additionally, 4,517 (91%) reported phoning and/or texting while driving; 4,467 (90%) of drivers said they talk on the phone while driving; 1,241 (25%) reported using a hands-free device "most of the time"; 4,467 (90%) of drivers reported texting while driving; 2,488 (50%) reported sending texts while driving on the freeway; 2,978 (60%) while in stop-and-go traffic or on city streets; and 4,319 (87%) at traffic lights. Those who drove more often were more likely to drive distracted. When asked about their capability to drive distracted, 46% said they were capable or very capable of talking on a cell phone and driving, but they felt that only 8.5% of other drivers were capable. In a multivariate model, 9 predictors explained 44% of the variance in DD, which was statistically significant, F (17, 4945) = 224.31; P <.0001; R(2) = 0.44. The four strongest predictors (excluding driving frequency) were self-efficacy (i.e., confidence) in driving while multitasking (β = 0.37), perception of safety of multitasking while driving (β = 0.19), social norms (i.e., observing others multitasking while driving; β = 0.29), and having a history of crashing due to multitasking while driving (β = 0.11). CONCLUSIONS Distracted driving is a highly prevalent behavior among college students who have higher confidence in their own driving skills and ability to multitask than they have in other drivers' abilities. Drivers' self-efficacy for driving and multitasking in the car, coupled with a greater likelihood of having witnessed DD behaviors in others, greatly increased the probability that a student would engage in DD. Most students felt that policies, such as laws impacting driving privilege and insurance rate increases, would influence their behavior.

Abstract
To increase an awareness of the developmental anatomy of the nasal cavity as it applies to the radiologic work-up of choanal atresia and frontoethmoidal cephaloceles, we report two cases that demonstrate potentially serious imaging pitfalls. Two neonates with nasopharyngeal obstruction were imaged with CT and MR. Both patients had surgically proved bilateral bony choanal atresia. In addition to choanal atresia, CT showed a radiolucent, or nonossified cribriform plate and mucoid secretions within the nasal fossa, adjacent to the cribriform plate, which approximated the attenuation of brain parenchyma. In one of the patients, a preoperative diagnosis of nasopharyngeal encephalocele resulted in surgical exploration. At surgery, however, the cartilaginous cribriform plate was found to be intact.

Abstract
We studied 59 seizure patients with CT, MR, and EEG to determine the efficacy of each in the detection of an epileptogenic focus. EEG was most sensitive (67%), MR was next (53%), and CT was least sensitive (42%). MR detected an abnormality in five patients (8%) in whom CT was negative. EEG was positive in each of these patients. CT failed to demonstrate any focal lesion not detected by MR. MR and CT detected focal abnormalities in seven patients (12%) who had negative EEGs. Five of the seven patients had brain tumors. Eighteen of the 26 patients who underwent surgery had positive CT and MR; 14 of these patients had tumors. The remaining eight patients who had surgery all had temporal lobectomies for intractable seizures; none had tumors. In the complex partial seizure subgroup of 34 patients, MR was positive in 44%, CT was positive in 29%, and EEG was positive in 80%. We consider MR to be the imaging procedure of choice for the detection of an epileptogenic focus in seizure patients. When indicated, CT may be performed as a second procedure to try to distinguish neoplasm from thrombosed vascular malformations and other lesions.

Abstract
The neurotoxic effects in cerebral angiography of three iodinated ionic contrast media, nonionic iopamidol, 25% mannitol, and saline controls were compared in 25 rabbits. Diatrizoate sodium meglumine was the most toxic agent, followed by diatrizoate and meglumine, iothalamate meglumine, and mannitol in terms of blood-brain barrier (BBB) disruption and coupled perfusion decline. HIPDm distribution was more sensitive than trypan blue extravasation for monitoring brain dysfunction. Iopamidol and saline controls exhibited no visual BBB breakdown or alteration in regional uptake of I-125 HIPDm, confirming the safety of nonionic iopamidol as compared with presently used ionic contrast media.
