    Abstract Abnormal cholesterol metabolism can lead to oxidative stress in the brain. Low-density lipoprotein receptor (LDLr) knockout mice are models for studying altered cholesterol metabolism and oxidative stress onset in the brain. Carbon nanodots are a new class of carbon nanomaterials that possess antioxidant properties. The goal of our study was to evaluate the effectiveness of carbon nanodots in preventing brain lipid peroxidation. LDLr knockout mice and wild-type C57BL/6J mice were treated with saline or 2.5 mg/kg bw of carbon nanodots for a 16-week period. Brains were removed and dissected into the cortex, midbrain, and striatum. We measured lipid peroxidation in the mouse brain tissues using the Thiobarbituric Acid Reactive Substances Assay and iron and copper concentrations using Graphite Furnace Atomic Absorption Spectroscopy. We focused on iron and copper due to their association with oxidative stress. Iron concentrations were significantly elevated in the midbrain and striatum of the LDLr knockout mice compared to the C57BL/6J mice, whereas lipid peroxidation was greatest in the midbrain and cortex of the LDLr knockout mice. Treatment with carbon nanodots in the LDLr knockout mice attenuated both the rise in iron and lipid peroxidation, but they had no negative effect in the C57BL/6J mice, indicating the anti-oxidative stress properties of carbon nanodots. We also assessed locomotor and anxiety-like behaviors as functional indicators of lipid peroxidation and found that treatment with carbon nanodots prevented the anxiety-like behaviors displayed by the LDLr knockout mice. Overall, our results show that carbon nanodots are safe and may be an effective nanomaterial for combating the harmful effects caused by lipid peroxidation.

    Abstract Background: In Lebanon, men who have sex with men (MSM) face high rates of stigma, discrimination, and violence. Minority stress, or the unique stressors related to anti-MSM stigma and discrimination, negatively impacts the mental health of MSM. These stressors are heightened for those with intersectional minority identities such as displaced Syrian MSM in Lebanon.
    Methods: In this qualitative study conducted in 2020-21, part of a larger study focused on the mental and sexual health risks among MSM, we collected qualitative data from Lebanese and displaced Syrian MSM living in Lebanon and analyzed reports of their experiences with stigma, mental health, and coping strategies. We conducted semi-structured, in-depth interviews with 12 displaced Syrian MSM and 13 Lebanese MSM.
    Results: Our findings highlight how MSM in Lebanon navigate stigma and the mental health risks that result. Common stressors among Lebanese and displaced Syrian MSM were related to finances, sexual orientation discrimination, and social isolation. Comparing the two groups, we found that stressors specific to displaced Syrian MSM were related to adverse childhood experiences, recent exposure to the Syrian war, displacement, and discrimination in Lebanon based on their intersectional identities as MSM and Syrians. For Lebanese participants, the most common stigma coping strategies were avoidance, drinking alcohol, using drugs, or having sex. As for displaced Syrian MSM, the most common stigma coping strategy was seeking the freely available mental health services offered to them through non-governmental organizations.
    Conclusion: Our findings suggest that increased targeted mental health and social support interventions, informed by the unique experiences of Lebanese and displaced Syrian MSM, are highly needed to improve the coping and mental health resources of all MSM in Lebanon.

    Abstract We aimed to assess the overall clinical impact of cardiac myosin inhibitors in hypertrophic cardiomyopathy (HCM). We performed a meta-analysis of published trials assessing the effect of cardiac myosin inhibitors (mavacamten and aficamten) on resting and Valsalva left ventricular outflow tract (LVOT) gradients and functional capacity in symptomatic HCM. The co-primary outcomes were mean percent change (mean difference [MD]) from baseline in LVOT gradient at rest and Valsalva LVOT gradient and the proportion of patients achieving New York Heart Association class improvement ≥1. The secondary outcomes included the mean percent change from baseline N-terminal pro-B-type natriuretic peptide, troponin I, and left ventricular ejection fraction (LVEF). A total of 4 studies (all randomized controlled trials, including 3 mavacamten-focused and 1 aficamten-focused trials) involving 463 patients were included in the meta-analysis. Compared with placebo, the cardiac myosin inhibitor group demonstrated statistically significant differences in the baseline percent change in mean LVOT gradient at rest (MD -62.48, confidence interval [CI] -65.44 to -59.51, p <0.00001) and Valsalva LVOT gradient (MD -54.21, CI -66.05 to -42.36, p <0.00001) and the proportion of patients achieving New York Heart Association class improvement ≥1 (odds ratio 3.43, CI 1.90 to 6.20, p <0.0001). Regarding the secondary outcomes, the intervention group demonstrated statistically significant reductions in mean percent change from baseline in N-terminal pro-B-type natriuretic peptide (MD -69.41, CI -87.06 to -51.75, p <0.00001), troponin I (MD, -44.19, CI -50.59 to -37.78, p <0.00001), and LVEF (MD -6.31, CI -10.35, -2.27, p = 0.002). In conclusion, cardiac myosin inhibitors may confer clinical and symptomatic benefits in symptomatic HCM at the possible expense of LVEF. Further trials with large sample sizes are needed to confirm our findings.

    Abstract Objective: To define applicant response to the preference signaling program and continuing virtual aspects of the 2022 Urology Residency Match to guide future decisions surrounding this process.
    Methods: We emailed an anonymous, de-identified 20-question, multiple choice survey to all applicants to our institution for the 2022 Urology Residency Match (RedCap). Where appropriate, comparisons were made to already published data collected in an identical manner from applicants to our institution for the 2021 Urology Residency Match.
    Results: Of the 418 survey recipients, 155 (37%) responded to our survey. A majority of applicants (83%) thought that preference signaling should remain in future years, and 66% of applicants matched to a program to which they had signaled or where they completed a subinternship. Geographic location of programs was ranked to have the highest impact on choice of programs for preference signaling. Fifty-two percent of 2022 applicants thought that interviews should remain virtual compared with 39% of 2021 applicants (P = .03). Twenty-one percent of 2022 applicants agreed that pre/post-interview socials were well-replicated virtually compared with 10% of 2021 applicants (P = .04).
    Conclusion: A majority of urology applicants were satisfied with the preference signaling program, suggesting that preference signaling should remain in future matches. A majority of urology applicants now favor the virtual interview platform. While it is gaining greater acceptance among applicants, the virtual platform generally still carries deficiencies. Further research of the urology match process is necessary for continued optimization of the program for all stakeholders.

    Abstract The SARS-CoV-2 XBB is a group of highly immune-evasive lineages of the Omicron variant of concern that emerged by recombining BA.2-descendent lineages and spread worldwide during 2023. In this study, we combine SARS-CoV-2 genomic data (
    Importance: Brazil was one the most affected countries by the SARS-CoV-2 pandemic, with more than 700,000 deaths by mid-2023. This study reconstructs the dissemination of the virus in the country in the first half of 2023, a period characterized by the dissemination of descendants of XBB.1, a recombinant of Omicron BA.2 lineages evolved in late 2022. The analysis supports that XBB dissemination was marked by the continuous emergence of indigenous lineages bearing similar mutations in key sites of their Spike protein, a process followed by continuous increments in transmissibility, and without repercussions in the incidence of severe cases. Thus, the results suggest that the epidemiological impact of the spread of a SARS-CoV-2 variant is influenced by an intricate interplay of factors that extend beyond the virus's transmissibility alone. The study also underlines the need for SARS-CoV-2 genomic surveillance that allows the monitoring of its ever-shifting composition.

    Abstract Introduction: Patient expectations and baseline health are important drivers of outcomes following major genitourinary reconstructive surgery for neurogenic bladder (NGB). Differences in expectations and quality of life (QoL) improvements among different populations with NGB remain insufficiently explored in the literature.
    Objective: To compare decisional regret (DR) and urinary-related QoL (UrQoL) in patients undergoing urinary diversion for NGB arising from spinal cord injury of acquired (A-SCI) and congenital (C-SCI) etiologies. We hypothesize that patients with A-SCI have higher expectations of improvement in QoL following surgery when compared with C-SCI, which may lead to higher DR and decreased UrQoL, postoperatively.
    Design: In this cross-sectional survey study, we compared A-SCI to C-SCI in terms of DR, UrQoL, and postoperative changes in self-reported physical health, mental health, and pain using validated patient-reported outcome measures.
    Setting: Participants were enrolled from a quaternary care institution via mail and MyChart.
    Participants: The A-SCI group consistied of 17 patients with traumatic spinal cord injury the C-SCI group was composed of 20 patients with spina bifida.
    Interventions: Not applicable.
    Main outcome measures: The Decisional Regret Scale, Short form- Qualiveen (SF-Qualiveen), and Patient-reported outcomes measurement Information system-10 (PROMIS-10) Global Health surveys.
    Results: The A-SCI group displayed poorer preoperative physical health than the C-SCI cohort, but absolute postoperative changes in this score, along with mental health score and pain level, were not significant after adjusting for baseline scores and follow-up time. SF-Qualiveen scores revealed significantly worse impact of NGB in UrQoL for A-SCI than for C-SCI when adjusted for other factors. No differences in DR were seen between the groups.
    Conclusions: Patients with A-SCI demonstrate lower self-reported baseline physical health compared with patients with C-SCI, which may have implications in setting patient expectations when undergoing urinary diversion. In this small cohort, we found a milder self-reported postoperative impact of NGB in UrQoL in patients with C-SCI.

    Abstract INTRODUCTION Patient-reported pads per day use is a widely used metric in grading the severity of stress urinary incontinence and guiding surgical decision-making, particularly in mild-to-moderate cases. We sought to compare patient-reported stress urinary incontinence severity by pads per day with objective findings on standing cough test. We hypothesize that patient-reported pads per day often underestimates stress urinary incontinence severity.
    Materials and methods: We retrospectively reviewed our male stress urinary incontinence surgical database and identified 299 patients with self-reported mild-to-moderate stress urinary incontinence who were evaluated with standing cough test prior to surgical intervention between 2007 and 2019. Patients were evaluated with the Male Stress Incontinence Grading Scale for urinary leakage during a standing cough test. This test has been shown to reliably and accurately predict surgical success. Binary logistic regression analysis was used to identify parameters associated with stress urinary incontinence upgrading in a multivariable model.
    Results: Among 299 patients with reported mild-to-moderate stress urinary incontinence, 101 (34%) were upgraded to severe stress urinary incontinence by standing cough test. Prior stress urinary incontinence surgery (OR 4.1, 95% CI 2.0-8.0, p < 0.0001) and radiation (OR 3.2, 95% CI 1.7-5.7, p < 0.0001) were significantly associated with Male Stress Incontinence Grading Scale upgrading in multivariable analysis.
    Conclusions: Roughly one-third of men who report mild-to-moderate stress urinary incontinence actually have severe incontinence observed on physical examination. All men being evaluated for stress urinary incontinence should undergo standing cough test to accurately grade incontinence severity and guide surgical management.
