RESUMO
PURPOSE: To describe the perioperative safety, functional and immediate post-operative oncological outcomes of minimally invasive RPLND (miRPLND) for testis cancer. METHODS: We performed a retrospective multi-centre cohort study on testis cancer patients treated with miRPLND from 16 institutions in eight countries. We measured clinician-reported outcomes stratified by indication. We performed logistic regression to identify predictors for maintained postoperative ejaculatory function. RESULTS: Data for 457 men undergoing miRPLND were studied. miRPLND comprised laparoscopic (n = 56) or robotic (n = 401) miRPLND. Indications included pre-chemotherapy in 305 and post-chemotherapy in 152 men. The median retroperitoneal mass size was 32 mm and operative time 270 min. Intraoperative complications occurred in 20 (4%) and postoperative complications in 26 (6%). In multivariable regression, nerve sparing, and template resection improved ejaculatory function significantly (template vs bilateral resection [odds ratio (OR) 19.4, 95% confidence interval (CI) 6.5-75.6], nerve sparing vs non-nerve sparing [OR 5.9, 95% CI 2.3-16.1]). In 91 men treated with primary RPLND, nerve sparing and template resection, normal postoperative ejaculation was reported in 96%. During a median follow-up of 33 months, relapse was detected in 39 (9%) of which one with port site (< 1%), one with peritoneal recurrence and 10 (2%) with retroperitoneum recurrences. CONCLUSION: The low proportion of complications or peritoneal recurrences and high proportion of men with normal postoperative ejaculatory function supports further miRPLND studies.

INTRODUCTION: Urethral diverticulum in a male is a rare entity and the literature is limited to case reports and small case series. The aim of our study is to characterize this disease in patients from three Mayo Clinic locations. MATERIALS AND METHODS: Chart analysis was performed of patients across all three Mayo Clinic sites that had International Classification of Diseases (ICD) codes corresponding to urethral diverticulum or urethral diverticulectomy via CPT code. Data were available for patients that were seen from 6/1/2003 through 10/5/2018. Patients were classified by age, etiology, presenting symptomatology, location, treatment, pathology, and postoperative outcomes. RESULTS: A total of 87 men met the initial search criteria with 52 having documented urethral diverticula. The most common presenting complaint in these men was incontinence (37%). The majority of diverticula (83%) were within the anterior urethra. The most common diagnostic modalities were retrograde urethrogram (46%) and cystoscopy (50%). Most diverticula were iatrogenic (77%). Of the men that were diagnosed, 42% went on to have diverticulectomy. Median follow up was 1.5 years. Eighteen percent of patients had persistent urinary symptoms following diverticulectomy with incontinence being the most common finding. Postoperative complications were experienced by 26% patients with the most prevalent complication being urethrocutaneous fistula. The patients who did not undergo diverticulectomy either had other surgical procedure to manage their coexisting conditions or were managed medically. CONCLUSION: Urethral diverticulum in males is a rare yet important entity that requires special consideration, especially in those who have had prior surgery within the lower urinary tract.

RESUMO
BACKGROUND: Alcohol consumption and related consequences is a problem on many college campuses. Tailgating parties before college sporting events may be contributing, however, little recent research has investigated alcohol consumption at these events. OBJECTIVE: The purpose of this study is to evaluate the drinking behaviors of college game day tailgate attendees and subsequent alcohol-related consequences. METHODS: Participants (N = 89; 44.9% female) were recruited from tailgates at a university in the Midwest United States on college football game days during fall 2014. Participants provided a breath sample, completed a questionnaire, and were given the opportunity to participate in a follow-up survey (n = 62) to assess resulting alcohol-related consequences. RESULTS: Over half of participants had BrACs greater than 0.000. However, one in three participants reported intentions to abstain from alcohol or to drink but not enough to get buzzed. Intoxication intentions were a significant and unique predictor of alcohol consumption and experience with alcohol-related consequences at follow-up. Conclusions/Importance: This study updates and extends the literature on alcohol-related consequences in the context of college football tailgates. The results suggest that consequences may be prevented through changes in intentions to become intoxicated.

PURPOSE: No consensus exists on the management of men with nonseminoma and viable nonteratomatous germ cell tumor in the postchemotherapy retroperitoneal lymph node dissection (pcRPLND) specimen after first-line chemotherapy. We analyzed surveillance versus different adjuvant chemotherapy regimens and the influence of time to pcRPLND on oncologic outcomes. METHODS: Data on 117 men treated with cisplatin-based first-line chemotherapy between 1990 and 2018 were collected from 13 institutions. All patients had viable nonteratomatous germ cell tumor in the pcRPLND specimen. Surgery was performed after a median of 57 days, followed by either surveillance (n = 64) or adjuvant chemotherapy (n = 53). Primary end points were progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS: After controlling for International Germ Cell Cancer Cooperative Group risk group and percent of viable malignant cells found at RPLND, no difference was observed between men managed with surveillance or adjuvant chemotherapy regarding PFS (hazard ratio [HR], 0.72 [95% CI, 0.32 to 1.6]; P = .4), CSS (HR, 0.69; 95% CI, 0.20 to 2.39; P = .6), and OS (HR, 0.78 [95% CI, 0.25 to 2.44]; P = .7). No statistically significant differences for PFS, CSS, or OS were observed on the basis of chemotherapy regimen or in men treated with pcRPLND ≤57 versus >57 days after first-line chemotherapy. Residual disease with <10% versus ≥10% viable cancer cells were associated with a longer PFS (HR, 3.22 [95% CI, 1.29 to 8]; P = .012). Relapse in the retroperitoneum was observed in 34 (29%) men. CONCLUSION: Men with a complete resection at pcRPLND and <10% viable cells have favorable outcomes without further treatment. Complete retroperitoneal resection seems more important than early pcRPLND.

INTRODUCTION: Current guidelines recommend surveillance in metastatic non-seminomatous germ cell tumour patients treated with first-line-chemotherapy and a complete clinical response (normalisation of serum tumour markers and residual masses <1 cm). However, this recommendation is based on a series including patients with good prognosis according to International Germ Cell Cancer Cooperative Group prognostic group (IGCCCG-PG). The aim of this study was to analyse the proportion of residual teratoma and survival among patients with intermediate/poor IGCCCG-PG and a complete clinical response after first-line-chemotherapy. MATERIAL & METHODS: This is a retrospective study of men with intermediate/poor IGCCCG-PG, who had a complete clinical response after first-line chemotherapy. Patients were either followed by surveillance or treated with post-chemotherapy retroperitoneal lymph node dissection (pcRPLND). RESULTS: Between 2009 and 2018, 143 men with intermediate (n = 83) or poor (n = 60) IGCCCG-PG were treated at 11 international centres. Among 33 patients treated with pcRPLND, the specimen showed teratoma and viable cancer in 16 (48%) and 4 (12%). During a median a 7-year follow-up, 20/110 (18%) patients managed with surveillance relapsed, of whom seven (6%) had a retroperitoneal-only relapse versus 2/33 patients managed with pcRPLND relapsed. No difference was observed regarding overall survival (OS) among men treated with pcRPLND or surveillance (5-year OS, 93% and 89%, p-value = 0.35). The median time-to-recurrence among men on surveillance was 1.3 years (range: 0.3-9.1), and the most common sites of relapses included retroperitoneum (11%), chest (5%), and bones (4%). CONCLUSIONS: While most men with intermediate/poor IGCCCG-PG harbour teratoma/cancer in the retroperitoneum despite a complete response to first-line-chemotherapy, only 6% managed with surveillance relapsed in the retroperitoneum. There was no significant difference in OS between the two groups.

OBJECTIVE: Urethral diverticulum is a rare, yet important condition for the female pelvic surgeon. We aimed to characterize the women who have been seen for this condition across the three Mayo Clinic locations. METHODS: Medical record review was performed for patients across all three Mayo Clinic sites (Rochester, Arizona, Florida) that had International Classification of Diseases, Ninth Revision, (ICD-9) and International Classification of Diseases, Tenth Revision, (ICD-10) codes corresponding to urethral diverticulum (ICD-9, 599.2; ICD-10, N36.1). We also performed a review of patients who underwent urethral diverticulectomy via Current Procedural Terminology (CPT) code 53235. Data were available for patients from June 1, 2003, to October 5, 2018. Patients were classified by age, etiology, presenting symptomatology, location, treatment, pathology, and postoperative outcomes. RESULTS: Four hundred forty-seven women met initial coding criteria for urethral diverticula, with 228 women having documented urethral diverticula. The most common presentations were irritative voiding symptoms (93) and infections (92). The most common diagnostic modality was radiographic imaging (198/228) with magnetic resonance imaging accounting for 157 cases. Etiology was unknown in the majority of cases (181/228). Of women who were diagnosed, 172 underwent diverticulectomy with 51 concurrent urethral sling placements. Final pathology demonstrated 2 cases of malignancy. Postoperative follow-up ranged from 0 months to 15 years (mean, 1.4 years; median, 4 months). Forty-three patients had persistent urinary symptoms after diverticulectomy with stress incontinence being the most common. Eight patients underwent subsequent sling placement. Fourteen patients had recurrence. CONCLUSIONS: This appears to be the largest reported series on female urethral diverticula, a rare yet important entity that requires special consideration. Most surgical cases found resolution of symptoms after diverticulectomy. Importantly, less than 2% of urethral diverticula were associated with malignancy.

A positive association between eating disorder (ED) symptoms and cigarette use exists. However, little is known about the association between ED symptoms and e-cigarette use, as well as how these symptoms are related to motives for using cigarettes and e-cigarettes. In this study, 716 college students (M age = 19.23, SD = 1.65; 61 % female) completed an online survey that included the Eating Pathology Symptoms Inventory, smoking and vaping questionnaires, and the Drinking Motives Questionnaire-Revised, which was modified for smoking and vaping. We examined mean differences in ED symptoms in lifetime (and past-month) cigarette and e-cigarette users versus non-users, and investigated correlations between ED symptoms and smoking and vaping motives. Finally, we evaluated whether biological sex influenced the results. Overall, 30.4 % of students reported lifetime smoking, 10.5 % reported past-month smoking, 23 % reported lifetime vaping, and 9.5 % reported past-month vaping. With the exception of higher mean scores for negative attitudes toward obesity in students reporting lifetime smoking versus never smoking after adjusting for sex (M = 5.97 vs. M = 4.52, t[713] = -3.76, q = 0.004), no significant mean differences emerged between those who used nicotine and those who did not, which reflected small to moderate effect sizes. Few associations were observed between ED symptoms and nicotine use motives. These findings suggest that the comorbidity between ED symptoms and smoking and vaping in a non-clinical sample is minimal, although additional research with larger sample sizes of males and females is needed.

BACKGROUND: Alcohol use and subsequent consequences are harmful for individual college students. Other students and the university can also be negatively impacted by the consequences of alcohol use. METHOD: A field-based study was used to assess the alcohol use environment at college parties. Researchers replicated a previous study by driving and walking a route to identify parties primarily on Thursday, Friday, and Saturday evenings between 9:00 PM and 1:00 AM across an academic year. Parties were randomly sampled. Hosts were asked for permission to enter the party at each sampled location. A census of partygoers was attempted at each party. Participants were asked to complete a brief survey and give a breath sample. All participants were recruited into a follow-up survey. Bivariate and multivariate analyses of individual-level and party-level factors associated with intoxication are presented. RESULTS: The research team identified 29 parties: 16 were approached, and 12 were surveyed. Overall, 112 participants were surveyed for a response rate of approximately 28.7% of partygoers. Controlling for demographic characteristics, consumption of shots of liquor/spirits was significantly associated with a five times greater risk for intoxication. Notably, drinking games were protective of breath alcohol concentration (BrAC) risk in this model. Individuals who reported engaging in drinking games were 74% less likely to report a BrAC above the U.S. legal limit, while controlling for underage drinking in the model. Several party characteristics were identified that increased overall BrAC at the parties, including whether the party was themed, if it was a Greek life party, and whether there were illicit drugs present. Notably, when intoxication is examined by gender and party theme, women are significantly more likely to be intoxicated at themed parties: 75% were above 0.08 at themed parties compared to 35% above 0.08 at non-themed parties. CONCLUSIONS: Field-based data collection methods can, and should, be modified to conduct needs assessment and evaluation of prevention programs on college campuses. The findings on this campus were different than the originally sampled campus. Prevention programs should target unique risks identified on each campus, and to respond to problematic party behaviors with comprehensive programming rather than policy-level bans.

Spontaneous or therapy-induced depigmentation in patients with melanoma has long been considered a favourable prognostic indicator. In this report, we isolated T cells infiltrating the depigmented skin of an HLA-A2+/DR4+ patient with melanoma, and detected a very high frequency of CD8+ T cells specific for melanocortin receptor 1 (MC1R), a hormone receptor involved in cutaneous pigmentation. In particular, tissue-infiltrating CD8+ T cells dominantly recognized the novel MC1R52-60 peptide epitope in an HLA-A2-restricted manner, and peptide-reactive CD8+ T cells were also detected in freshly isolated peripheral blood from this patient. Although type 1 CD4+ T-cell responses against MC1R were not detected in fresh tissue isolates, short-term in-vitro stimulation of peripheral blood lymphocytes resulted in the rapid expansion of CD4+ T cells reactive against novel HLA-DR4-presented epitopes derived from the MC1R protein (i.e. MC1R82-95, MC1R105-118 and MC1R149-161). MC1R peptide-specific CD8+ T-cell clones isolated from the depigmented skin of this patient were characterized by comparatively low functional avidity for specific major histocompatibility complex-peptide complexes and were poorly lytic; however, these effector cells were capable of secreting both interferon-gamma and granzyme B against relevant target cells in vitro, and may have played an important role in the induction of leucoderma in situ in this patient.

Whereas normally expressed at sites of cell-to-cell contact in adult epithelial tissues, recent studies have shown that the receptor tyrosine kinase EphA2 is overexpressed in numerous epithelial-type carcinomas, with the greatest level of EphA2 expression observed in metastatic lesions. In the current study, we have assessed EphA2 expression in archived renal cell carcinoma (RCC) tissues as it relates to patient disease course. Using specific anti-EphA2 monoclonal antibody 208 and immunohistochemistry, we evaluated EphA2 protein expression levels in RCC specimens surgically resected from 34 patients (including 30 conventional clear-cell RCC, 3 papillary, and 1 chromophobic RCC cases) resulting in clinical cures. Regardless of histopathologic subtype, RCC lesions expressing higher levels of EphA2 tended to be of a higher grade (P < 0.05) and larger (P = 0.093), more-highly-vascularized tumors (P = 0.005). Perhaps most notable, the degree of EphA2 overexpression (versus normal matched autologous kidney tissue) seemed predictive of short-term (<1 year) versus longer-term (> or =1 year) disease-free interval (P < 0.001) and of overall survival (P < 0.001) among the RCC patients evaluated. These data suggest that EphA2 expression level may serve as a useful prognostic tool in the clinical management of patients who have been successfully treated with surgery, but who are at greater risk for accelerated disease recurrence and who have a poorer prognosis.
