RESUMO

PURPOSE: An unsafe hematocrit threshold for men receiving testosterone therapy (TT) has never been tested. This study seeks to determine whether secondary polycythemia among men receiving TT confers an increased risk of major adverse cardiovascular events (MACE) and venous thromboembolic events (VTE). MATERIALS AND METHODS: Using a multi-institutional database of 74 million patients, we identified 2 cohorts of men with low testosterone (total testosterone <350 ng/dl) who received TT and subsequently either developed polycythemia (5,887) or did not (4,2784). Polycythemia was defined as hematocrit ≥52%. As a secondary objective, we identified 2 cohorts of hypogonadal men without polycythemia, who either did (26,880) or did not (27,430) receive TT. Our primary outcome was the incidence of MACE and VTE in the first year after starting TT. We conducted a Kaplan-Meier survival analysis to assess differences in MACE and VTE survival time, and measured associations following propensity score matching. RESULTS: A total of 5,842 men who received TT and developed polycythemia were matched and compared to 5,842 men who did not develop polycythemia. Men with polycythemia had a higher risk of MACE/VTE (number of outcomes: 301, 5.15%) than men who had normal hematocrit (226, 3.87%) while on TT (OR 1.35, 95% CI 1.13-1.61, p <0.001). In hypogonadal men who received testosterone, no increased risk of MACE and VTE was identified as compared to hypogonadal men naïve to TT. CONCLUSIONS: Developing polycythemia while on TT is an independent risk factor for MACE and VTE in the first year of therapy. Future research on the safety of TT should include hematocrit as an independent variable.

RESUMO

Although COVID-19 vaccine access has increased nationwide, vaccination rates have been slow-moving, with many studies showing significant vaccine hesitancy in the U.S. We conducted an online survey using Amazon Mechanical Turk (MTurk) to identify reasons for vaccine hesitancy among unvaccinated adults between June 30 and July 1, 2021. We found that 58% of unvaccinated respondents were worried about unknown long-term adverse effects. Of these, 41% believed that the COVID-19 vaccines can negatively impact reproductive health and or fertility, and 38% were unsure of the effects on fertility. Our study demonstrates that fear regarding COVID-19 vaccine adverse effects and belief that they can negatively impact fertility is a major cause of vaccine hesitancy in the United States. We identified that urban residents, married individuals, those born outside the U.S., those with health insurance, and people with higher education and income greater than $100,000 felt that the vaccine would affect fertility more than their counterparts did. Finally, we found that 48% of unvaccinated respondents cited 'more information and research conducted on the COVID-19 vaccines' as the action that would most encourage vaccine uptake.

RESUMO

INTRODUCTION: Within the United States, the number of players participating in baseball increased by nearly 21% to 15.9 million between 2014 and 2019. Additionally, batting helmets with face-masks are encouraged yet optional in youth baseball as well as college baseball and softball. in light of inconsistencies in safety equipment enforcement and usage, this study aims to perform a comparative analysis of the number and frequency of baseball and softball-related craniofacial injuries (CFis). METHODS: Data regarding baseball and softball-related injuries were gathered from the National Electronic Injury Surveillance System database from 2011 to 2020. Craniofacial injuries were isolated and organized into 5-year age groups beginning with 5 to 9 years and ending with 25 to 29 years of age. Data was further stratified by location and type of injury. Injury types specifically reported in this study included concussion, contusion, fracture, and laceration. RESULTS: Distribution of injuries across age groups differed significantly between baseball and softball ( P < 0.001). When comparing the 10 to 14 year old group to the 15 to 19 year old group, we found that concussions and head contusions comprise a significantly greater proportion of all injuries in softball than in baseball. Conversely, facial fractures, facial lacerations, and mouth lacerations comprise a significantly greater proportion ofinjuries in baseball than in softball. CONCLUSION: Future prospective studies aiming to better characterize the within-game nature of these reported CFIs would certainly be beneficial in guiding the baseball and softball communities toward consideration of implementing maximally efficacious updates to current safety equipment standards.

RESUMO

BACKGROUND: Prior to the COVID-19 pandemic, urology was one of the specialties with the lowest rates of telemedicine and videoconferencing use. Common barriers to the implementation of telemedicine included a lack of technological literacy, concerns with reimbursement, and resistance to changes in the workplace. In response to the COVID-19 pandemic declared in March 2020, the delivery of urological services globally has quickly shifted to telemedicine to account for the mass clinical, procedural, and operative cancellations, inadequate personal protective equipment, and shortage of personnel. OBJECTIVE: The aim of this study was to investigate current telemedicine usage by urologists, urologists' perceptions on the necessity of in-person clinic appointments, the usability of telemedicine, and the current barriers to its implementation. METHODS: We conducted a global, cross-sectional, web-based survey to investigate the use of telemedicine before and after the COVID-19 pandemic. Urologists' perceived usability of telemedicine was assessed using a modified Delphi approach to create questions based on a modified version of the validated Telehealth Usability Questionnaire (TUQ). For the purposes of this study, telemedicine was defined as video calls only. RESULTS: A total of 620 urologists from 58 different countries and 6 continents participated in the survey. Prior to COVID-19, 15.8% (n=98) of urologists surveyed were using telemedicine in their clinical practices; during the pandemic, that proportion increased to 46.1% (n=283). Of the urologists without telemedicine experience, interest in telemedicine usage increased from 43.7% (n=139) to 80.8% (n=257) during the COVID-19 pandemic. Among urologists that used telemedicine during the pandemic, 80.9% (n=244) were interested in continuing to use it in their practice. The three most commonly used platforms were Zoom, Doxy.me, and Epic, and the top three barriers to implementing telemedicine were patients' lack of technological comprehension, patients' lack of access to the required technology, and reimbursement concerns. CONCLUSIONS: This is the first study to quantify the use, usability, and pervading interest in telemedicine among urologists during the COVID-19 pandemic. In the face of this pandemic, urologists' usage of telemedicine nearly tripled, demonstrating their ability to adopt and adapt telemedicine into their practices, but barriers involving the technology itself are still preventing many from utilizing it despite increasing interest.

RESUMO

The protein kinase D (PKD) family of proteins are important regulators of tumor growth, development, and progression. CRT0066101, an inhibitor of PKD, has antitumor activity in multiple types of carcinomas. However, the effect and mechanism of CRT0066101 in bladder cancer are not understood. In the present study, we show that CRT0066101 suppressed the proliferation and migration of four bladder cancer cell lines in vitro. We also demonstrate that CRT0066101 blocked tumor growth in a mouse flank xenograft model of bladder cancer. To further assess the role of PKD in bladder carcinoma, we examined the three PKD isoforms and found that PKD2 was highly expressed in eight bladder cancer cell lines and in urothelial carcinoma tissues from the TCGA database, and that short hairpin RNA (shRNA)-mediated knockdown of PKD2 dramatically reduced bladder cancer growth and invasion in vitro and in vivo, suggesting that the effect of the compound in bladder cancer is mediated through inhibition of PKD2. This notion was corroborated by demonstrating that the levels of phospho-PKD2 were markedly decreased in CRT0066101-treated bladder tumor explants. Furthermore, our cell cycle analysis by flow cytometry revealed that CRT0066101 treatment or PKD2 silencing arrested bladder cancer cells at the G2/M phase, the arrest being accompanied by decreases in the levels of cyclin B1, CDK1 and phospho-CDK1 (Thr161) and increases in the levels of p27Kip1 and phospho-CDK1 (Thr14/Tyr15). Moreover, CRT0066101 downregulated the expression of Cdc25C, which dephosphorylates/activates CDK1, but enhanced the activity of the checkpoint kinase Chk1, which inhibits CDK1 by phosphorylating/inactivating Cdc25C. Finally, CRT0066101 was found to elevate the levels of Myt1, Wee1, phospho-Cdc25C (Ser216), Gadd45α, and 14-3-3 proteins, all of which reduce the CDK1-cyclin B1 complex activity. These novel findings suggest that CRT0066101 suppresses bladder cancer growth by inhibiting PKD2 through induction of G2/M cell cycle arrest, leading to the blockade of cell cycle progression.

RESUMO

Purpose: Adolescent and young adult (AYA) cancer patients frequently demonstrate sexual dysfunction; however, there is a lack of data quantifying the severity and frequency. Methods: Males aged 18-39 years, diagnosed with cancer of any kind and who were scheduled to begin, were actively receiving, or had completed cancer treatment within 6 months, were offered validated surveys during their oncology appointment. These surveys included the International Index of Erectile Function (IIEF-6), Masturbation Erection Index (MEI), 36-Item Short Form Survey, and 5-point Likert scales to assess their desire and ability to engage in sex and masturbation. Results: Forty subjects completed the IIEF survey with a mean score of 17.7 ± 11, erectile dysfunction (ED) prevalence accordingly was 58%. Thirty-eight subjects completed the MEI with a mean score of 25.3 ± 5.3, ED prevalence was again 58%. Age and IIEF scores demonstrated a statistically significant (p < 0.05, n = 38) Pearson's correlation coefficient of 0.40, patients younger than 30 years had an ED prevalence of 72% (mean IIEF 13), whereas patients aged 30 years and older had an ED prevalence of 45% (mean IIEF 22). All treatment modalities had ED rates >30%: chemotherapy demonstrated the highest prevalence at 64% (mean IIEF 17), whereas radiation therapy had the lowest prevalence at 33% (mean IIEF 23). Conclusion: This study demonstrates that the prevalence of sexual dysfunction among male AYA patients undergoing treatment for cancer is high. AYA oncologists should discuss potential sexual health concerns when treating this population. The exact cause of ED (non-organic vs. organic) within this group should be explored further.

RESUMO

Erectile Dysfunction (ED) is defined as the inability to achieve and maintain an erection sufficient for sexual intercourse. Available treatments for ED provide only symptomatic relief, which is for the most part temporary. Regenerative therapies such as Low Intensity Shockwave, Platelet-Rich Plasma, and Stem Cell therapy can potentially provide a "cure" for ED by reversing the underlying pathology of ED rather than just treating the symptoms. Low Intensity Shockwave therapy is the most evidence based at this point and is thought to act by improving penile blood flow, repairing previous nerve damage, and activating stem cells. Stem Cell therapy takes advantage of the self-replicative potential of stem cells to create new corporal tissue, but also to recruit host cells and angiogenic factors to stimulate endogenous repair. Platelet-Rich Plasma therapy uses concentrated growth factors that already exist within the bloodstream to repair damaged nerves and increase penile blood flow. The use of combination restorative therapy may provide an additive or synergistic benefit greater than any one therapy alone because of its overlapping mechanisms of action on the penis but is a topic that remains to be studied.

RESUMO

INTRODUCTION: Several studies have investigated the association between erectile dysfunction (ED), its treatment, and female sexual dysfunction, but the impact of males blaming their female partners for their ED remains unknown. AIMS: To investigate whether women who are blamed by their male partners for their ED experience worse overall sexual function and satisfaction. METHODS: We performed a global, cross-sectional web-based survey to investigate female perceptions of ED. We distributed the 30-item survey via email, Reddit, Amazon Mechanical Turk, and Facebook. Women 18 years of age or older were eligible to participate and answered questions based on a 5-point Likert scale. Women were grouped by ages 18-29, 30-39, and 40 and older. MAIN OUTCOME MEASURES: The survey collected data that included general demographics and questions regarding experiencing male blame for ED and its relationship with each subject's sexual health and wellness. RESULTS: A total of 13,617 females participated in the survey. Of the women surveyed, 79% have experienced their partner losing their erection during sexual activity and approximately 1 out of 7 women (14.7%) had experienced being blamed by their partner for loss of their erection. Women who were blamed for their partner's ED were more likely to end the sexual encounter, were less sexually satisfied, and were more likely to end relationships due to their partner's ED. CONCLUSION: Approximately 1 out of 7 women have experienced male blame for their partner's ED which is associated with negative impacts on female mental health, sexual satisfaction and the success of the overall partnership. Because of its widespread impact on female wellness, male blame should be considered during evaluation of female sexual history and men must be educated on the significant impact their reactions during intimacy have on their female partners and their relationships as a whole.
