The association between frailty, hypogonadism, and postoperative outcomes among men undergoing radical cystectomy. Urol Oncol 2024; 42:161.e9-161.e16. [PMID: 38262867 DOI: 10.1016/j.urolonc.2024.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 12/25/2023] [Accepted: 01/08/2024] [Indexed: 01/25/2024]
Abstract
INTRODUCTION Hypogonadism is associated with frailty, lower health-related quality of life, decreased muscle mass, and premature mortality, which may predispose patients to poor postoperative outcomes. We aimed to determine the prevalence of hypogonadism in men undergoing radical cystectomy (RC) and whether hypogonadism and frailty are associated with adverse postoperative outcomes. MATERIALS AND METHODS The IBM MarketScan database was used to identify men who underwent RC between 2012 and 2021. Frailty was determined using published Hospital Frailty Risk Score ranges. Patients were considered to have hypogonadism if diagnosed within 5 years prior to RC. Length of stay (LOS), complications, emergency department (ED) visits and inpatient readmissions were compared. Sub-group analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. RESULTS Among 3,727 men who underwent RC, 226 (6.1%) had a diagnosis of hypogonadism. Overall, 565 (15.2%) men were low-risk frailty, 2,214 (59.4%) intermediate-risk frailty, and 948 (25.4%) were high-risk frailty, and men with hypogonadism were significantly more frail compared to men without hypogonadism (P = 0.027). There was no significant difference in LOS, complications, or rate of ED visits and inpatient readmissions between cohorts (P > 0.05). However, high-risk frailty was associated with an increased risk of 90-day ED visit (HR 1.19, 95%CI 1.00-1.41, P = 0.049) and 90-day readmission (HR 1.60, 95%CI 1.29-1.97, P < 0.001) after RC. Among men with hypogonadism, 58 (25.7%) were on TRT. There was no significant difference in frailty, LOS, complications, or 90-day ED visits or 90-day inpatient readmissions between patient with hypogonadism prescribed TRT and those without TRT. CONCLUSIONS These findings suggest that hypogonadism and preoperative frailty may be important to evaluate prior to undergoing RC.

The broad reach and inaccuracy of men's health information on social media: analysis of TikTok and Instagram. Int J Impot Res 2024; 36:256-260. [PMID: 36402921 PMCID: PMC9676765 DOI: 10.1038/s41443-022-00645-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 11/07/2022] [Accepted: 11/11/2022] [Indexed: 11/21/2022]
Abstract
Social media (SoMe) offers great potential to expand access to health information, but a significant proportion of users consume its content instead of consulting a physician. We sought to quantify the volume and characterize the accuracy of men's health-related content on TikTok and Instagram. We searched TikTok and Instagram for the terms: testosterone, erectile dysfunction, male infertility, semen retention, Peyronie's disease, and vasectomy. The top 10 hashtags for each term were used to estimate the total impressions for each term on each platform, and posts were then characterized by creator type, content type, and accuracy (1 to 5 scale). TikTok had 2,312,407,100 impressions and Instagram had 3,107,300 posts across all topics. Semen retention had the most impressions on TikTok (1,216,074,000) and posts on Instagram (1,077,000). Physicians created only a small portion of total TikTok and Instagram posts (10.3% and 12.9%, respectively). Across all topics, the accuracy of content was poor (2.6 ± 1.7), however, physician posts were more accurate than non-physician posts (mean 4.2 ± 1.2 vs 2.3 ± 1.6, p < 0.001, respectively). Men's health content is popular on TikTok and Instagram but is not accurate. We recommend that physicians actively engage in SoMe to address misinformation.

Hypogonadism, frailty, and postoperative outcomes among men undergoing radical nephrectomy. J Surg Oncol 2024. [PMID: 38685749 DOI: 10.1002/jso.27638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Accepted: 03/26/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND AND OBJECTIVE Hypogonadism and frailty may impact postoperative outcomes for men undergoing radical nephrectomy (RN). We aimed to determine the prevalence of hypogonadism in men undergoing RN and whether hypogonadism and frailty are associated with adverse postoperative outcomes. METHODS We identified men undergoing RN between 2012 and 2021 using the IBM Marketscan database. Frailty was determined using the Hospital Frailty Risk Score (HFRS). Patients were considered to have hypogonadism if diagnosed <5 years before RN. Length of stay (LOS), complications, emergency department (ED) visits, and readmissions were evaluated between men with and without hypogonadism at the time of surgery. Subgroup analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. RESULTS Among 13 598 men who underwent RN, 972 (7.1%) had hypogonadism. Men with hypogonadism were more frail compared to men without hypogonadism (HFRS: median: 8.2, interquartile range [IQR]: 5.2-11.7 vs. median: 7.0, IQR: 4.3-10.7, p < 0.001) and had increased incidence of postoperative ileus (13.0% vs. 10.8%, p = 0.045), acute kidney injury (25.5% vs. 21.6% p = 0.005), and cardiac arrest (1.2% vs. 0.6%, p = 0.034). Hypogonadism was not associated with LOS, 90-day ED visit or readmission. However, high-risk frailty was associated with increased risk of 90-day ED visit (hazard ratio [HR]: 2.1, 95% confidence interval [95% CI]: 1.9-2.4, p < 0.001) and 90-day inpatient readmission (HR: 2.6, 95% CI: 2.2-3.1, p < 0.001), compared to low-risk frailty patients. Among men with hypogonadism, TRT was not associated with any postoperative outcomes. CONCLUSIONS Hypogonadism and frailty should be considered in the preoperative evaluation for men undergoing RN as risk factors for adverse postoperative outcomes.

Reproductive Urology Consultation Is an Opportunity to Evaluate for Medical Comorbidity: The Prevalence of Elevated Blood Pressure and Obesity at Fertility Evaluation. Cureus 2024; 16:e57071. [PMID: 38681328 PMCID: PMC11052603 DOI: 10.7759/cureus.57071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/22/2024] [Indexed: 05/01/2024] Open
Abstract
Purpose To evaluate the prevalence of elevated blood pressure (EBP), hypertension (HTN), and obesity among men presenting for fertility evaluation. Methods We retrospectively evaluated all men presenting for male infertility consultation at a single institution from 2000 to 2018. Blood pressure (BP) measurements were abstracted from the electronic health record, and EBP/HTN was defined according to American Heart Association/American College of Cardiology guidelines (systolic blood pressure (SBP) ≥ 120 mmHg or diastolic blood pressure (DBP) ≥ 80 mmHg). Descriptive statistics were used to compare demographic and clinical characteristics of men with and without EBP/HTN or obesity (BMI ≥ 30 kg/m2), and logistic regression was utilized to determine associations with EBP/HTN. Results Among 4,127 men, 1,370 (33.2%) had a recorded SBP and DBP within one year of their initial visit. EBP/HTN was noted in 857 (62.6%) men. A total of 249 (18.2%) men were obese, 863 (63.0%) were non-obese, and 258 (18.8%) did not have BMI recorded. HTN and obesity were jointly present in 195 (17.5%) men. There was no significant difference in age, ethnicity, or total motile sperm count between men with and without EBP/HTN. On multivariable analysis, BMI was significantly associated with EBP/HTN (OR: 1.13, 95% CI: 1.08-1.18, p < 0.001). Conclusion More than half of men presenting for initial fertility consultation have either EBP, obesity, or both. Reproductive urologists should consider routinely screening for these conditions and encourage men to seek further evaluation and treatment, when appropriate.

Novel reference range values for serum testosterone: a cross-sectional study of 200,000 males. J Endocrinol Invest 2024:10.1007/s40618-024-02319-0. [PMID: 38383878 DOI: 10.1007/s40618-024-02319-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 01/23/2024] [Indexed: 02/23/2024]
Abstract
PURPOSE To better understand the effects of aging, metabolic syndrome, diurnal variation, and seasonal variation on serum testosterone levels in the context of current guideline statements on testosterone deficiency. METHODS This cross-sectional study utilized the United Kingdom Biobank. Physical examination, anthropomorphic measurements, and laboratory evaluation were performed at the time of enrollment from 2006 to 2010. The primary outcomes were the effect of age, the presence of metabolic syndrome, the time of day, and the month of the year on serum testosterone levels. RESULTS Among 197,883 included men, the 5th, 25th, 50th, 75th and 95th percentile testosterone levels in men without metabolic syndrome were significantly higher than those in men with metabolic syndrome at every decade of life (p < 0.001). The average testosterone level within each group (men without metabolic syndrome vs. men with) was clinically similar across decade of life (12.43 in 40's 12.29 in 50's 12.24 in 60's vs. 10.69 in 40's 10.56 in 50's 10.63 in 60's respectively). Average testosterone levels decreased with blood draws later in the day ranging from 10.91 to 12.74 nmol/L (p < 0.01). Similarly, there was seasonal variation in serum testosterone ranging from 11.86 to 12.18 nmol/L (p < 0.01). CONCLUSIONS We found significant variation in serum testosterone according to the presence of metabolic syndrome and time of laboratory draw, but not according to age. These data challenge the prior dogma of age-related hypogonadism and favor an individualized approach towards serum testosterone measurement and interpretation. However, further studies are needed to correlate these population-based data with individuals' hypogonadal symptoms.

Prevalence of sexual dysfunction and pursuit of sexual medicine evaluation among male physicians-a survey. Int J Impot Res 2024:10.1038/s41443-024-00827-4. [PMID: 38245626 DOI: 10.1038/s41443-024-00827-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 01/02/2024] [Accepted: 01/10/2024] [Indexed: 01/22/2024]
Abstract
We sought to characterize the prevalence of sexual dysfunction and barriers to treatment among male physicians. Between June and December 2022, male physicians were invited to complete a questionnaire regarding sexual function. Surveys were disseminated electronically via social media and professional medical societies using Qualtrics (Provo, UT). In totla, 235 responses were included in the final analysis. The mean age of respondents was 36.3 ± 7.4 years (range 23-72). 27 (11.5%) reported having seen a doctor for sexual health. Of these 27, 40.7% saw a physician for erectile dysfunction, 29.6% for low libido, 22.2% for premature ejaculation, 7.4% for delayed ejaculation, and 33.3% for other concerns. An additional 29 (12.3%) considered establishing care for sexual issues but didn't, mostly due to being too busy. 46 (19.6%) respondents reported having taken medication to improve erectile function. Therefore, in a cohort of young male physicians, 23.8% had seen or considered seeing a doctor for sexual health concerns, and nearly 1 in 5 had taken medication for erectile dysfunction. Male physicians appear to be at higher risk for sexual dysfunction than the general population and face significant and unique barriers in access to care for sexual dysfunction.

Abstract
OBJECTIVE To compare the prevalence of abnormal hormone parameters among men with and without oligospermia to determine the value of universal hormonal screening during initial fertility evaluation. MATERIALS AND METHODS We retrospectively evaluated men who underwent semen analysis and hormonal evaluation (morning testosterone [T] and follicle-stimulating hormone [FSH]) between January 2002 and May 2021. Sperm concentration was dichotomized at 15 million/mL according to World Health Organization (WHO) criteria. We compared median and interquartile range (IQR) T and FSH levels according to sperm concentration using Kruskal-Wallis test. Differences in prevalence of low testosterone (<300 ng/dL) and abnormal FSH (>7.6mIU/mL) were determined using chi-square test. RESULTS 1164 men had a morning serum T. There was no difference in median T among men with normal vs abnormal sperm concentration (316 ng/dL, IQR 250-399 vs 316 ng/dL, IQR 253-419; P = .52). FSH was measured in 1261 men. Median FSH was higher among men with sperm concentration <15 million/mL (6.0IU/mL, IQR 3.9-10.7 vs 3.8IU/mL, IQR 2.7-5.7; P < .001). Among men with ≥15 million/mL concentration, 44.1% were found to have low T (P = .874) and 10.8% had an FSH ≥7.6 mIU/mL (P < .001). Among men with ≥15 million/mL sperm concentration who underwent both T and FSH evaluation, 43.6% had at least 1 hormonal abnormality. CONCLUSION Almost half of men with normal sperm concentration had low T. As low T may have long-term implications for both fertility and overall health, providers should consider universal T screening in men presenting for fertility evaluation.

Abstract
Objective Varicocele is considered the most common reversible cause of male infertility. However, some men do not clinically improve after surgical repair. We aimed to identify preoperative factors associated with decreased semen parameters and clinical "downgrading" of total motile sperm count (TMSC) following varicocelectomy. Methods We examined men with preoperative laboratory testing and pre- and postoperative semen analyses (SA) who underwent varicocelectomy between 2010 and 2020. Ejaculate volume, sperm motility, sperm concentration, TMSC, and clinical grade of TMSC (in vitro fertilization: <5M sperm, intrauterine insemination: 5-9M sperm, natural pregnancy: >9M sperm) were used to determine postoperative outcomes. Demographic and clinical factors were compared between cohorts. Results Among 101 men who underwent varicocelectomy, 35 (34.7%) had decreased postoperative TMSC with a median follow-up of 6.6 months (interquartile range 3.9-13.6 months). Eleven (10.9%) men experienced TMSC clinical "downgrading" following surgery. Clinical grade III varicocele was significantly associated with decreased sperm motility on postoperative SA (OR 4.1, 95% CI 1.7-10.0, p=0.002), and larger left testicle volume (OR 1.4, 95% CI 1.1-1.8, p=0.02) was associated with clinical "downgrading" after varicocelectomy. Conclusion A small but significant proportion of men experienced a "downgrading" of semen parameters after varicocelectomy. Larger left testis size was associated with clinical downgrading, whereas clinical grade III varicoceles were associated with lower post-treatment sperm motility. These data are critical for preoperative patient counseling.

Factors associated with undergoing microdissection testicular sperm extraction among men with non-obstructive azoospermia following evaluation by a reproductive urologist. Transl Androl Urol 2023; 12:1062-1070. [PMID: 37554532 PMCID: PMC10406537 DOI: 10.21037/tau-23-76] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/02/2023] [Indexed: 08/10/2023] Open
Abstract
BACKGROUND Microdissection testicular sperm extraction (mTESE) is the gold standard treatment for men with non-obstructive azoospermia (NOA). However, many men do not elect to pursue this surgical intervention. We aimed to identify factors associated with NOA patients undergoing mTESE after initial evaluation by a reproductive urologist (RU) through a retrospective cohort study. METHODS We retrospectively reviewed NOA patient who underwent evaluation by a RU between 2002-2018. Demographic and clinical data were collected. Our primary outcome was electing to undergo mTESE. RESULTS 44.4% (75/169) of NOA men underwent mTESE. These patients earned significantly higher median neighborhood income ($133,000 vs. $97,000, P<0.001), spent fewer years trying to conceive before seeking care {1.3 [interquartile range (IQR): 1-3] vs. 2.3 (IQR: 1-5), P=0.012}, and were more likely to be married (79.7% vs. 53.9%, P=0.001). On univariate analysis, married men [odds ratio (OR) 3.37, 95% confidence interval (CI): 1.67-6.79, P=0.001] and men with higher neighborhood income (OR 1.14, 95% CI: 1.06-1.21, P<0.001) were more likely to undergo mTESE, while couples attempting to conceive for a longer period of time prior to initial evaluation were less likely to undergo mTESE (OR 0.79, 95% CI: 0.68-0.92, P=0.003). On multivariable regression analysis, marital status and years attempting to conceive remained significantly associated with NOA patients undergoing mTESE (OR 4.61, 95% CI: 1.16-18.25, P=0.03; OR 0.67, 95% CI: 0.52-0.88, P=0.003, respectively). CONCLUSIONS Higher neighborhood income and marital status were positively associated with patients undergoing mTESE, while couples who attempted to conceive for a longer period of time before seeking infertility care were less likely to undergo mTESE.

Abstract
PURPOSE Medicinal and recreational cannabis use has grown exponentially, however, its effect on testicular function and spermatogenesis remains uncertain. The aim of this study was to evaluate the association between cannabis use and semen parameters in a cohort of Asian-American men with unknown fertility. MATERIALS AND METHODS Asian men were recruited to complete an online survey and submit a semen sample. Semen analysis, demographic data, lifestyle factors, and cannabis use habits were collected. Linear and logistic regression analyses were used to determine. RESULTS Among the 112 men included in this study, 51 used cannabis at least once in their lifetime, 30 men used cannabis at least once in the last 12 months, and 26 men used cannabis at least once in the last 30 days. Adjusted linear regression analyses identified an association between cannabis use in the previous 30 days and worse sperm morphology (β: -0.45, p=0.025) and sperm motility (β: -1.64, p=0.016). However, when stratifying by subfertile semen quality (i.e., WHO criteria), no association was identified between semen quality and cannabis use. Lower sperm morphology and motility are partially associated with recent cannabis use, while all other semen parameters are not. CONCLUSIONS We did not observe any consistent associations between cannabis use on any semen parameters in Asian-American men. Further studies within the field are needed to explore racial and ethnic differences in semen quality and lifestyle factors.

Abstract
BACKGROUND Male factor infertility (MFI) is a common medical condition which requires high-quality research to guide clinical practice; however, systematic reviews (SRs) and meta-analyses (MAs) often vary in quality, raising concerns regarding the validity of their results. We sought to perform an objective analysis of SRs and MAs in MFI treatment and management and to report on the quality of published literature. METHODS A comprehensive search in PubMed/MEDLINE and Embase was used to identify relevant publications. Primary search terms were male infertility, male sterility, and male subfertility. Two authors independently performed searches, screened citations for eligibility, extracted data for analysis, and graded methodological quality using the validated AMSTAR (A Measurement Tool to Assess Systematic Reviews) instrument, a validated tool used in the critical appraisal of SRs/MAs. RESULTS Of 27 publications met inclusion criteria and were included in the analysis. Mean AMSTAR score (± SD) among all publications was 7.4 (1.9) out of 11, reflecting "fair to good" quality. Non-pharmacological medical treatment for MFI was the most commonly assessed intervention (n = 13, 48.1%). No publications met all AMSTAR criteria. While the number of SRs/MAs has increased over time (P = 0.037), the quality of publications has not significantly changed (P = 0.72). SRs/MAs of the Cochrane Library had higher AMSTAR score than non-Cochrane SRs/MAs (8.5 vs 6.3, P = 0.002). CONCLUSIONS The methodological quality of SRs/MAs should be assessed to ensure high-quality evidence for clinical practice guidelines in MFI treatment and management. This review highlights a need for increased effort to publish high-quality studies in MFI treatment and management.

Abstract
UNLABELLED INTRODUCTION We sought to describe clinical characteristics and identify prognostic factors among patients with primary malignancies of the epididymis (PMEs). MATERIALS AND METHODS The Surveillance, Epidemiology, and End Results (SEER) database (1975-2015) was queried to identify patients with PME. Descriptive statistics and multivariable Cox proportional hazards models were used. RESULTS Eighty-nine patients with PME were identified. Median age was 57 years (5-85), and median overall survival (OS) was 16.8 years. The most commonly represented histologies were rhabdomyosarcoma (19.1%), B-cell lymphoma (16.9%), leiomyosarcoma (16.9%), and liposarcoma (12.4%). In multivariable analysis, tumor size ≥ 4 cm was associated with worse OS (HR = 4.46, p = 0.01) compared to tumors < 4 cm. Patients with nonsarcomatoid histology had OS similar to patients with sarcomatoid histology (HR = 0.95, p = 0.92). Disease with regional invasion (HR = 5.19, p = 0.007) and distant metastasis (HR = 29.80, p = 0.0002) had worse OS compared to localized disease. Receipt of radiotherapy was associated with enhanced OS (HR = 0.10, p = 0.006), whereas receipt of chemotherapy was not associated with OS. CONCLUSIONS We describe the largest cohort of PMEs to date. Larger lesions and tumor stage were independently associated with poor overall survival, while receipt of radiotherapy was associated with enhanced overall survival.

Racial and socioeconomic disparities in retroperitoneal lymph node dissection and survival in nonseminomatous germ cell tumor: A population-based study. Urol Oncol 2021; 39:197.e1-197.e8. [PMID: 33423934 DOI: 10.1016/j.urolonc.2020.12.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Revised: 12/09/2020] [Accepted: 12/17/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND Though testicular cancer is the most common cancer in young men, there is a paucity of epidemiologic studies examining sociodemographic disparities in adjuvant therapy and outcomes. We examined the associations of sociodemographic factors with retroperitoneal lymph node dissection (RPLND) and survival among patients with nonseminomatous germ cell tumors (NSGCTs). METHODS Within the Surveillance Epidemiology and End Results database (2005-2015), we identified 8,573 patients with nonseminomatous germ cell tumors. Multivariable logistic regression and Fine-Gray competing-risks regression models were constructed to examine the association of sociodemographic factors (neighborhood SES (nSES), race, and insurance) with, respectively, adjuvant RPLND within 1 year of diagnosis and cancer-specific mortality. RESULTS Patients in the lowest nSES quintile (OR 0.59, 95% CI = 0.40-0.88, P = 0.01) and Black patients (OR 0.41, 95% CI = 0.15-1.00, P= 0.058) with stage II disease were less likely to receive RPLND compared to those in the highest quintile and White patients, respectively. Stage III patients with Medicaid (OR 0.64, 95% CI = 0.46-0.89, P= 0.009) or without insurance (OR 0.46, 95% CI = 0.27-0.76, P= 0.003) were less likely to receive RPLND compared to patients with private insurance. Lowest quintile nSES patients of all disease stages and Black patients with stage I disease (HR = 2.64, 95% CI = 1.12-6.20, P = 0.026) or stage II disease (HR=4.93, 95% CI = 1.48-16.44, P = 0.009) had higher risks of cancer-specific mortality compared to highest quintile nSES and White patients, respectively. CONCLUSIONS This national study found multilevel, stage-specific sociodemographic disparities in receipt of RPLND and survival.

Bupivacaine local anesthetic to decrease opioid requirements after radical cystectomy: Does formulation matter? Urol Oncol 2020; 39:369.e1-369.e8. [PMID: 33303378 DOI: 10.1016/j.urolonc.2020.11.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 09/21/2020] [Accepted: 11/04/2020] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Reduction of opioids is an important goal in the care of patients undergoing radical cystectomy (RC). Liposomal bupivacaine (LB) has been shown to be a safe and effective pain reliever in the immediate postoperative period and has been reported to reduce postoperative opioid requirements. Since the liposomal formulation is predicated on slow systemic absorption, the amount of bupivacaine administered is notably higher than that typically used with standard bupivacaine (SB) formulations. In addition, LB is costly, not universally available, and studies comparing this formulation to SB are lacking. We sought to determine if there is a difference in postoperative opioid requirements in patients who receive LB vs. high dose SB at the time of RC. METHODS In May 2019 we transitioned to administration of high-volume SB injected intraoperatively at the time of RC. This prospective cohort was compared to a historical cohort of patients who received injection of LB at the time of surgery. Primary endpoints included postsurgical opioid use measured in morphine equivalent dose (MED) and patient-reported Numeric Rating Scale (NRS) pain scores and length of stay. All patients were managed using principles of enhanced recovery after surgery (ERAS). RESULTS From May 2019 through August 2019, 28 patients underwent RC and met eligibility criteria to receive SB at the time of surgery. They were compared to a historical cohort of 34 patients who received LB between November 2017 and July 2018. There was no difference in MED exposure either in the postanesthesia care unit (SB 9.0 ± 8.9 MED vs. LB 6.5 ± 9.4 MED, P= 0.29) or during the remainder of the hospital stay (SB 36.8 ± 56.9 MED vs. LB 42.1 ± 102.5 MED, P= 0.81), no difference in NRS pain scores on postoperative day 1 (SB 2.6 ± 1.6 vs. LB 2.1 ± 1.7, P= 0.23), day 2 (SB 2.4 ± 1.8 vs. LB 1.9 ± 1.6, P= 0.19), or day 3 (SB 1.9 ± 1.8 vs. LB 1.7 ± 1.7, P= 0.69) and no difference in length of stay (SB 5.0 ± 1.7 days, LB 4.9 ± 3.3 days, P= 0.93). Subgroup analysis of open RC and robotic-assisted RC showed no significant difference in MED or pain scores between LB and SB patients. CONCLUSIONS Among patients undergoing RC under ERAS protocol there was no significant difference in postoperative opioid consumption, NRS pain scores, or length of stay among patients receiving SB compared to LB.

A population-level analysis of nonsquamous penile cancer: The importance of histology. Urol Oncol 2020; 39:136.e1-136.e10. [PMID: 33257222 DOI: 10.1016/j.urolonc.2020.11.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 11/07/2020] [Accepted: 11/15/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Nonsquamous penile cancers comprise 5% of penile malignancies, though their clinicopathologic features and prognostic significance remain unknown. We used a national cancer registry to detail clinical characteristics and compare cancer-specific mortality (CSM) of nonsquamous cancers with squamous cell carcinoma (SCC). METHODS The Surveillance, Epidemiology, and End Results (SEER) database (1975-2016) was queried to identify adults with nonsquamous penile cancer and penile SCC. Multivariable Fine and Gray competing-risks regression, propensity score matching, and cumulative incidence plots were used. RESULTS 666 men with nonsquamous penile cancer and 5,894 men with penile SCC were identified. The most commonly represented nonsquamous histological subtypes were Kaposi sarcoma (n = 183, 27.5%), melanoma (n = 74, 11.1%), basal cell carcinoma (n = 65, 9.8%), and extramammary Paget disease (n = 42, 6.3%). Cumulative incidence plots revealed a 10-year CSM rate of 32.6% in the nonsquamous penile cancer group and 25.6% in the matched penile SCC group (P < 0.0001). Among Kaposi sarcoma patients and matched SCC patients, we found a 10-year CSM rate of 29.6% in the Kaposi sarcoma group and 15.3% in the penile SCC group (P = 0.002). Similarly, a comparison of penile melanoma patients with matched SCC patients revealed a 10-year CSM rate of 38.4% in the melanoma group and 16.6% in the SCC group (P = 0.002). There was no difference in CSM between patients with basal cell carcinoma and SCC. In a sensitivity analysis limiting year of diagnosis to 2000 and onward, we found no difference in CSM between the general nonsquamous cohort or the Kaposi sarcoma cohort and matched SCC patients, but contemporary melanoma patients maintained worse CSM with a 10-year rate of 38.4% vs. 15.8% in matched SCC patients (P = 0.045). CONCLUSIONS The most common nonsquamous penile cancers are Kaposi sarcoma, melanoma, and basal cell carcinoma. Overall, CSM is higher in nonsquamous penile cancers as compared to stage-matched SCC. Outcomes are similar in modern patients, likely due to improved control of systemic HIV in patients with Kaposi sarcoma. However, men with penile melanoma continue to experience a higher rate of CSM.

Deep learning enabled prediction of 5-year survival in pediatric genitourinary rhabdomyosarcoma. Surg Oncol 2020; 36:23-27. [PMID: 33276260 DOI: 10.1016/j.suronc.2020.11.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Accepted: 11/15/2020] [Indexed: 01/16/2023]
Abstract
BACKGROUND Genitourinary rhabdomyosarcoma (GU-RMS) is a rare, pediatric malignancy originating from embryonic mesenchyme. Current approaches to prognostication rely upon conventional statistical methods such as Cox proportional hazards (CPH) models and have suboptimal predictive ability. Given the success of deep learning approaches in other specialties, we sought to develop and compare deep learning models with CPH models for the prediction of 5-year survival in pediatric GU-RMS patients. METHODS Patients less than 20 years of age with GU-RMS were identified within the Surveillance, Epidemiology, and End Results (SEER) database (1998-2011). Deep neural networks (DNN) were trained and tested on an 80/20 split of the dataset in a 5-fold cross-validated fashion. Multivariable CPH models were developed in parallel. The primary outcomes were 5-year overall survival (OS) and disease-specific survival (DSS). Variables used for prediction were age, sex, race, primary site, histology, degree of tumor extension, tumor size, receipt of surgery, and receipt of radiation. Receiver operating characteristic curve analysis was conducted, and DNN models were tested for calibration. RESULTS 277 patients were included. The area under the curve (AUC) for the DNN models was 0.93 for OS and 0.91 for DSS. AUC for the CPH models was 0.82 for OS and 0.84 for DSS. The DNN models were well-calibrated: OS model (slope = 1.02, intercept = -0.06) and DSS model (slope = 0.79, intercept = 0.21). CONCLUSIONS A deep learning-based model demonstrated excellent performance, superior to that of CPH models, in the prediction of pediatric GU-RMS survival. Deep learning approaches may enable improved prognostication for patients with rare cancers.

Abstract
OBJECTIVE To assess the efficacy, safety, and outcomes of sacral nerve stimulation (SNS) for Parkinson's disease (PD) patients with overactive bladder symptoms. METHODS We retrospectively reviewed PD patients who underwent Stage I SNS. Demographics, urodynamic data, and baseline voiding function were analyzed. Efficacy and safety of treatment were determined by rate of progression to Stage II, explantation, and surgical revision. Long-term outcomes were assessed using voiding diaries and/or clinic notes. RESULTS Sixty percent (9/15) experienced ≥50% improvement in urinary parameters and proceeded to Stage II. There was no significant difference in age, body mass index, comorbidities, PD disease duration, or levodopa equivalent daily dose between successful and nonsuccessful Stage I patients. However, 100% of female patients experienced Stage I success compared to 44% of male PD patients (P = .04). Individuals with >12-month follow-up experienced an average reduction of 6 voids/day. No patients required revision or explantation of their device at latest clinic follow-up (22.2 ± 7.8 months). Higher maximal urethral closure pressures, detrusor pressure at maximum flow rate (PdetQmax), post-void residual volume, and mean bladder outlet obstruction index were observed in the Stage I trial failures. CONCLUSION At our institution, PD patients have a similar rate of progression to Stage II compared to the general population. SNS is an effective therapy that should be considered among the treatment options for PD patients with overactive bladder symptoms. Urodynamic parameters associated with obstruction may be predictive of SNS failure in PD patients and may help guide patient selection, however further studies are needed.

Abstract
PURPOSE To describe clinical characteristics and identify prognostic factors among men with testicular sarcoma, and to compare survival with other testicular cancers. METHODS The surveillance, epidemiology, and end results (SEER) database (1975-2016) was queried to identify adults with testicular sarcoma. Multivariable Cox proportional hazards, Fine and Gray competing-risks regression, propensity score matching, and Kaplan-Meier analyses were used. RESULTS 230 men were included in this study. Median age at diagnosis was 58 years (range 18-94), and median OS was 10.3 years. Patients with tumors larger than 8 cm in size had worse OS (HR 1.88, p = 0.016) compared to patients with tumors < 8 cm. Disease with distant metastasis was associated with worse OS (HR 4.70, p < 0.0001) and worse CSS (HR 11.41, p < 0.0001) as compared to disease localized to the testis. Men with rhabdomyosarcoma had worse CSS (HR 3.25, p = 0.03) as compared to men with liposarcoma. Testicular sarcoma patients had worse OS than matched patients with either seminomatous germ cell tumors (GCTs, p < 0.0001) or nonseminomatous GCTs (p = 0.0019), and similar survival to matched patients with sex cord stromal tumors, testicular lymphoma, or sarcomas of the lower limb-the most common anatomic site of origin of soft tissue sarcomas. CONCLUSIONS In the largest cohort of men with testicular sarcoma to date, we identified tumor size, disease extent, and rhabdomyosarcoma histology as independent predictors of worse survival. Stage-adjusted survival was worse as compared to men with GCTs, and similar to men with sex cord stromal tumors, testicular lymphoma, and sarcomas of other primary sites.

Abstract
BACKGROUND: Radical cystectomy (RC) often requires a prolonged course of opioid medications for postoperative pain management. We implemented a Reduced Opioid Utilization (ROU) protocol to decrease exposure to opioid medications. OBJECTIVE: To determine the impact of the ROU protocol on opioid exposure, pain control, inpatient recovery, and complication rates among patients who underwent RC. METHODS: The ROU protocol includes standardized recovery pathways, a multimodal opioid-sparing pain regimen, and improved patient and provider education regarding non-opioid medications. Opioid exposure was calculated as morphine equivalent dose (MED), and was compared between RC patients following the ROU protocol and patients who previously followed our traditional pathway. Opioid-related adverse drug events (ORADEs), pain scores, length of stay, and 90-day complications, readmission, and mortality were also compared between cohorts. RESULTS: 104 patients underwent RC, 54 (52%) of whom followed the ROU protocol. ROU patients experienced a statistically significant decrease in opioid exposure in the post-anesthesia care unit (p = 0.003) and during their postoperative recovery (85.7±21.0 MED vs 352.6±34.4 MED, p < 0.001). The ROU protocol was associated with a statistically significant decrease in ORADEs after surgery. There was no significant difference in average pain scores, length of stay, readmissions, or 90-day complication or mortality rates. CONCLUSIONS: The ROU protocol decreased opioid use by 77% without compromising pain control or increasing the rate of complications. This study demonstrates the efficacy of non-opioid medications in controlling postoperative pain, and highlights the role providers can play to decrease patient exposure to opioids after RC surgery.

Abstract
BACKGROUND Brain metastases from prostate cancer are rare and poorly described. We sought to assess the proportion of brain metastases arising from prostate cancer and to detail clinical characteristics, treatment modalities, and survival outcomes. METHODS We retrospectively identified and reviewed the charts of 31 patients with intraparenchymal brain metastases from prostate adenocarcinoma seen at our institution from 2008 to 2018. RESULTS Among all patients with brain metastases, the proportion originating from prostate adenocarcinoma was 0.86%. The median age at the time of brain metastasis diagnosis was 69 (range, 57-90). The median original Gleason score was 8 (range, 6-10), and the median prostate-specific antigen at the time of brain metastasis was 60 ng/mL (range, 0.34-4600). The median months from initial cancer diagnosis to brain metastasis was 81 (range, 3-195). The median number of brain metastases was 2 (range, 1-5). Patients had concurrent metastases to bone (100%), lung (48%), and liver (35%). Median overall survival was 3 months (range, 0.4-25.0). Treatment of the brain metastases was correlated with an increase in median survival from 1.2 months to 4.6 months with radiosurgery (hazard ratio = 0.11, P = 0.001) and surgical resection plus radiotherapy to 13 months (hazard ratio = 0.05, P < 0.001). All patients died of advanced, systemic disease and not of their intracranial disease. CONCLUSIONS Brain metastasis from prostate cancer constitutes a small fraction of total brain metastases, but is associated with poor prognosis and is seen in the setting of advanced, castrate resistant disease. These data enable treating physicians to appropriately counsel their patients with prostate adenocarcinoma brain metastasis.

Abstract
BACKGROUND Average paternal age in the United States has increased substantially in the last few decades. Children of advanced age fathers have a higher incidence of early onset cancer and neuropsychiatric disease. OBJECTIVES To quantify the number of population adjusted cases of early-onset cancer and neuropsychiatric disease in children attributable to increasing paternal age in the United States. METHODS Paternal age in the United States from 1972 to 2015 was collected using the National Vital Statistics System (NVSS). Population attributable fraction and paternal age-specific cumulative incidence rates of several cancers and neuropsychiatric disorders were obtained from peer-reviewed publications. Paternal age-specific birth rates were correlated with paternal age-specific cumulative incidence rates to determine the number of attributable cases of disease caused by advancing age of fathers in the United States. RESULTS The 2015 birth cohort in the United States is estimated to expect 9.2% more cases of acute lymphoblastic leukemia (ALL) diagnosed before 16 years of age (157 additional cases), 13.2% more cases of embryonal tumors in children <5 years of age (209 additional cases), and 13.0% more cases of breast cancer in females younger than 40 years old (424 additional cases) compared to the 1972 birth cohort. We can estimate to expect 10.5% more cases of schizophrenia diagnosed before 21 years of age (2864 additional cases), 6.3% more cases of autism spectrum disorder (ASD) in adolescents <17 years of age (2934 additional cases), 4.5% more cases of anorexia nervosa (AN) in females 8-30 years old (620 additional cases), and 9.2% more cases of bipolar disorder in young patients 16-25 years old (252 additional cases) in the 2015 birth cohort compared to the 1972 birth cohort. CONCLUSION Increasing paternal age in the United States is associated with a substantial increase in the number of cases of early-onset cancer and neuropsychiatric disease in offspring.

Abstract
INTRODUCTION Bicycle seat pressure on the perineum may impair arousal and clitoral erection, likely contributing to genital pain and numbness experienced by female cyclists. AIM We aimed to identify the association between genital pain and numbness experienced by female cyclists and female sexual dysfunction (FSD). METHODS Female cyclists were recruited to complete an online survey using the Female Sexual Function Index (FSFI), a validated questionnaire to assess FSD. Cyclist demographics, experience, preferred riding style, use of ergonomic cycle modifications, and genital discomfort while riding were also queried. Multivariate logistic regression analysis was used to evaluate risk factors of FSD. MAIN OUTCOME MEASURES The main outcome was FSFI score, which is used to diagnose FSD when the FSFI score is <26.55. RESULTS Of the survey respondents, 178 (53.1%) completed the survey and FSFI questionnaire. Mean age was 48.1 years (±0.8 standard error [SE]), and the average riding experience was 17.1 years (±0.9 SE). Overall, 53.9% of female cyclists had FSD, 58.1% reported genital numbness, and 69.1% reported genital pain. After adjusting for age, body mass index, relationship status, smoking history, comorbidities, and average time spent cycling per week, females who reported experiencing genital numbness half the time or more were more likely to have FSD (adjusted odds ratio [aOR], 6.0; 95% CI, 1.5-23.6; P = .01), especially if localized to the clitoris (aOR, 2.5; 95% CI, 1.2-5.5; P = .02). Females that reported genital pain half the time or more while cycling also were more likely to have FSD (aOR, 3.6; 95% CI, 1.2-11.1; P = .02). Cyclists experiencing genital pain within the first hour of their ride were more likely to have FSD (aOR, 12.6; 95% CI, 2.5-63.1; P = .002). Frequency and duration of cycling were not associated with FSD. Analysis of FSFI domains found that the frequency of numbness was correlated with decreased arousal, orgasm, and satisfaction during intercourse, whereas the frequency of pain significantly reduced arousal, orgasm, and genital lubrication. CLINICAL IMPLICATIONS Female cyclists that experience numbness and/or pain have higher odds of reporting FSD. STRENGTHS & LIMITATIONS Our study includes a validated questionnaire to assess FSD and queries specific characteristics and symptoms of genital pain and genital numbness; however, the study is limited by its cross-sectional survey design. CONCLUSION This study highlights the need for cyclists to address genital pain and numbness experienced while cycling, and future studies are required to determine if alleviating these symptoms can reduce the impact of cycling on female sexual function.

Predicting Pathology From Imaging in Children Undergoing Resection of Congenital Lung Lesions. J Surg Res 2018; 236:68-73.

Abstract
BACKGROUND Prenatal magnetic resonance imaging (MRI) is increasingly obtained to define congenital lung lesions (CLL) for surgical management. Postnatal, preoperative computed tomography (CT) provides further clarity at the cost of radiation. Depending on the lesion identified, the indication for resection remains controversial. We investigated the differences in detail found on prenatal MRI and postnatal CT compared with final pathology to determine their utility in preoperative decision-making. MATERIALS AND METHODS All children undergoing resection of CLLs at a single institution between July 2009 and February 2018 were retrospectively identified. Their imaging, operative, and pathology reports were compared. All imaging studies were examined by pediatric radiologists with experience in prenatal CLL diagnosis. RESULTS Fifty-five patients underwent CLL resection during the study period with 31 undergoing prenatal MRI, 45 postnatal CT, and 22 both. Resection was performed before 6 mo of age in 62% of patients. In the cohort undergoing both imaging studies, pathologic CLL diagnosis correlated with prenatal MRI and CT in 82% and 100% of patients, respectively (P = 0.13). Eight patients had systemic feeding vessels, of which 38% were identified on MRI, and 88% on CT (P = 0.13). Both studies had a specificity of 100% for detecting systemic feeding vessels. CONCLUSIONS For children where prenatal MRI detected a systemic feeding vessel, CT was redundant for preoperative planning but had greater sensitivity. Ultimately, the CLL type predicted from postnatal CT was not significantly different from that predicted by prenatal MRI; however, both imaging modalities had some level of discrepancy with pathology.

[PMID: 29873411 DOI: 10.1002/jor.24064] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Accepted: 05/21/2018] [Indexed: 02/04/2023]
Abstract
The purpose of the review was to synthesize the current literature regarding the effect of miRNA on biological processes known to be involved in tendon and tenocyte development and homeostasis. Using multiple databases, a systematic review was performed with a customized search term crafted to identify any study examining micro-RNA in relation to tendon and/or tenocytes. Results were classified based on the following categories: Gene expression, tenocyte development and differentiation, tendon tissue repair, and tenocyte senescence. A total of 3,112 potentially relevant studies were reviewed, and after exclusion criteria was applied, 15 investigations were included in the final analysis. There were 14 specific miRNA included in this review, with 11 studies reporting on tendon-related gene expression, five reporting on tendon development and/or tenocyte differentiation, six reporting on tendon tissue repair, and five reporting on tenocyte senescence. The miR-29 family was the most commonly reported micro-RNA in the investigation. We also report on a number of micro-RNA which are associated with both positive and negative effects on tendon homeostasis. © 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Quality Measures in Orthopaedic Sports Medicine: A Systematic Review. Arthroscopy 2017; 33:1896-1910. [PMID: 28655476 DOI: 10.1016/j.arthro.2017.04.014] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 03/18/2017] [Accepted: 04/03/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE To report the current quality measures that are applicable to orthopaedic sports medicine physicians. METHODS Six databases were searched with a customized search term to identify quality measures relevant to orthopaedic sports medicine surgeons: MEDLINE/PubMed, EMBASE, the National Quality Forum (NQF) Quality Positioning System (QPS), the Agency for Healthcare Research and Quality (AHRQ) National Quality Measures Clearinghouse (NQMC), the Physician Quality Reporting System (PQRS) database, and the American Academy of Orthopaedic Surgeons (AAOS) website. Results were screened by 2 Board-certified orthopaedic surgeons with fellowship training in sports medicine and dichotomized based on sports medicine-specific or general orthopaedic (nonarthroplasty) categories. Hip and knee arthroplasty measures were excluded. Included quality measures were further categorized based on Donabedian's domains and the Center for Medicare and Medicaid (CMS) National Quality Strategy priorities. RESULTS A total of 1,292 quality measures were screened and 66 unique quality measures were included. A total of 47 were sports medicine-specific and 19 related to the general practice of orthopaedics for a fellowship-trained sports medicine specialist. Nineteen (29%) quality measures were collected within PQRS, with 5 of them relating to sports medicine and 14 relating to general orthopaedics. AAOS Clinical Practice Guidelines (CPGs) comprised 40 (60%) of the included measures and were all within sports medicine. Five (8%) additional measures were collected within AHRQ and 2 (3%) within NQF. Most quality measures consist of process rather than outcome or structural measures. No measures addressing concussions were identified. CONCLUSIONS There are many existing quality measures relating to the practice of orthopaedic sports medicine. Most quality measures are process measures described within PQRS or AAOS CPGs. CLINICAL RELEVANCE Knowledge of quality measures are important as they may be used to improve care, are increasingly being used to determine physician reimbursement, and can inform future quality measure development efforts.

A critical review of the Pfiesteria hysteria hypothesis. MARYLAND MEDICAL JOURNAL (BALTIMORE, MD. : 1985) 1998; 47:133-6.

Abstract
Mass hysteria or mass psychogenic illness is the spread of the belief of an illness (symptoms and the origins of the symptoms) through a population. The characteristics of mass psychogenic illness were reviewed and compared to the recent outbreak of human illness in the Pocomoke region in Maryland in the summer of 1997. The findings suggest that the nature of the symptoms complex--the onset and recovery course; the absence of secondary gain or job-related stress for most of the symptomatic persons; the predominance of males in the symptomatic group; and the baseline emotional stability of all persons examined--are inconsistent with the reported features of psychogenic illness in response to unknown environmental or chemical toxins. Although there may be individuals who exhibited hypochondriacal, hysterical, or other functionally based reactions, the recent outbreak of Pfiesteria-related illness probably does not represent an episode of mass psychogenic illness.

Neurobehavioral complaints of symptomatic persons exposed to Pfiesteria piscicida or morphologically related organisms. MARYLAND MEDICAL JOURNAL (BALTIMORE, MD. : 1985) 1998; 47:127-9.

Abstract
Over the next year, additional persons in Maryland may be at risk for exposure of toxic Pfiesteria or morphologically related organisms. These persons may present with a variety of memory and other behavioral complaints. This paper examines the kinds of complaints that persons with a documented Pfiesteria-related syndrome have compared to a nonexposed control group. The exposed group was more likely to report difficulties with concentration, forgetfulness, prospective memory, and information overload as well as feelings of confusion, bewilderment, and uncertainty as direct effects of toxin exposure. The exposed group was also more likely to report feeling uneasy, on edge, nervous, and shaky, which is probably a reaction to their newly acquired cognitive deficits and uncertainty about their recovery. In contrast, retrograde memory loss, disturbances of language or social behavior, depression, anger, hostility, or diminished activity levels are not symptoms that exposed persons are likely to report.

Psychologic adjustment of watermen with exposure of Pfiesteria piscicida. MARYLAND MEDICAL JOURNAL (BALTIMORE, MD. : 1985) 1998; 47:130-2.

Abstract
Preliminary study of the psychologic adjustment of watermen with exposure to Pfiesteria piscicida was conducted on watermen with the most severe exposures and their occupationally matched controls. Participants in the exposed group were seven symptomatic recreational and commercial fishermen who had direct exposure to the Pocomoke River or other estuarial waters on Maryland's Eastern Shore before, during, and/or after periods of documented fish kills and Pfiesteria activity. The control group included eight commercial fishermen who worked on the ocean side of the Eastern Shore and had no reported exposure to estuaries with documented Pfiesteria activity. Both exposed symptomatic and nonexposed watermen completed the Profile of Mood States to assess depression, anxiety, and other relevant mood states as part of their participation in the larger investigation of the human health effects of Pfiesteria piscicida. Preliminary results suggest that both exposed symptomatic and nonexposed watermen are psychologically healthy and exhibit what psychologists refer to as the classic Iceberg Mood Profile. The Iceberg Profile is characterized by endorsement of symptoms suggestive of high energy, enthusiasm and positive mood (e.g., lively, active, energetic, cheerful, vigorous, etc.) and relative minimization of symptoms suggestive of negative or depressed mood (e.g., tense, anxious, restless, grouchy, forgetful). Therefore, the Pfiesteria-related symptom complex documented in the exposed watermen cannot be explained by functional or psychiatric factors and is probably due to exposure.

Abstract
OBJECTIVE Research indicates that African-American women have a significantly higher prevalence of obesity, a markedly lower prevalence of eating disorders, and greater satisfaction with their bodies than Euro-American women. One potential contributing explanation for this difference may be differential body type preferences between the men in the two communities. METHOD Sixty-three African-American and 116 Euro-American men were asked to rank, in order of attractiveness, a series of silhouettes of women of varying sizes. Additionally, they answered questions concerning their current relationships. RESULTS Euro-Americans chose significantly thinner figures, and reported wishing their girlfriends would lose weight significantly more often than African-Americans. DISCUSSION These differential preferences may translate into greater pressure within the Euro-American community for women to be thin than in the African-American community; however, a small effect size suggests that factors other than race contribute to men's body type preferences.
