RESUMEN

CONTEXT: Focal therapy has emerged as a promising option to treat well-selected men with localised prostate cancer while preserving healthy prostate tissue and key structures, such as the urethral sphincter and neurovascular bundles. However, how this tissue preservation may translate into improved outcomes, particularly into improved sexual outcomes, is still an active research field. OBJECTIVE: We conducted a systematic review and meta-analysis of the literature to summarise the existing evidence, in order to provide patients with updated data on what to expect after treatment and help identify gaps in current knowledge that may warrant future research. EVIDENCE ACQUISITION: A systematic literature search was conducted on Medline, EMBASE, Scopus, and Web of Science. The search strategy was defined using the "litsearchr" function in R based on a preliminary "naïve" search using the following terms on Medline: (("focal therapy" OR "focal treatment") AND ("prostate cancer") AND ("sexual function" OR "erectile function")). A total of 42 studies, comprising 3117 patients treated and 2352 with available sexual outcomes, were included in the qualitative data synthesis and 26 in a random-effect meta-analysis. EVIDENCE SYNTHESIS: The five-item International Index of Erectile Function (IIEF-5) was the most frequently used questionnaire (30/42 studies), with completion rates ranging from 24% to 100% at 18-24 mo. A decrease was noted at 3 mo (IIEF-5 decrease estimate -3.70 [95% confidence interval -4.43, -2.96]), with improvements at 6 mo (-2.18 [-2.91, -1.46]) and 12 mo (-2.14 [-2.96, -1.32]). Studies in which patients had an altered baseline sexual function were more likely to report a significant and durable postoperative decrease in erectile function scores. The patient-reported outcome questionnaires used were not designed for a diverse population. Functional outcomes were not the primary endpoint and have not been reported consistently in most studies considered. CONCLUSIONS: Focal therapy led to changes in erectile function in most cases under the significance threshold of the patient-reported outcome questionnaires used. However, patients should be counselled according to their baseline erectile function. More research is warranted to detail aspects other than erectile function, such as ejaculation or orgasm. The early postoperative period appears key to study sexual changes after focal therapy, while only a moderate decrease is expected at 12 mo. PATIENT SUMMARY: We reviewed the published literature detailing the sexual consequences of focal therapy for localised prostate cancer using patient-reported outcome questionnaires. Patients were likely to describe a significant decrease in their erectile function at 3 mo, with improvements noted at 6 and 12 mo. The results obtained may not be reproducible in a more diverse population, and further research is warranted to better study aspects other than erectile function, such as ejaculation or orgasm.

RESUMEN

We present a Letter to the Editor in response to the article by Chinsky et al. titled "Medical Student Perspectives on Their Role as Emerging Physicians During the COVID-19 Pandemic." The authors highlighted that a greater proportion of preclinical students felt more obligated to volunteer in the context of healthcare staff shortages, compared to clinical students. As final year medical students, we propose additional reasons based on our personal experiences that may contribute to clinical students feeling less inclined to volunteer during the pandemic. Specifically, we believe that the priorities of clinical students may affect their willingness to volunteer given the challenge of balancing private study and clinical placement. Furthermore, we believe that the psychological difficulties that often accompany clinical placement may affect clinical students' views on volunteering. We also briefly outline solutions that may solve these issues. Ultimately, positive attitudes in students need to be sustained throughout the medical degree so that the future generation of doctors is better equipped to face a future crisis and beyond.

RESUMEN

We present a letter to the editor in response to the article by Nikiforova et al. "Impact of A Required, Longitudinal Scholarly Project in Medical School: a Content Analysis of Medical Students' Reflections". We discuss our experiences of undertaking a similar module in our medical school and examine the authors' use of feedback in their analysis. We also present our views on the importance of feedback and the aspects that we feel maximise students experiencing with undertaking a longitudinal research project.

RESUMEN

Klinefelter syndrome (KS) is a common cause of non-obstructive azoospermia (NOA). Advances in fertility preservation (FP) techniques, such as the use of microdissection testicular sperm extraction (micro-TESE), have improved sperm retrieval rates (SRR) up to 40-50% in this population. Age has been suggested to have an impact on FP, postulating that sperm production may deteriorate over time due to germ cell loss. As such, sperm retrieval for patients with KS at a younger age has been proposed to further improve SRR; however, whether such practice pragmatically improves SRR is yet to be determined, and controversy remains with concerns over trauma caused by FP procedures on further impairment of testicular function. There has also been a debate on the ethics of performing FP procedures in the pediatric population. Optimizing FP for patients with KS invariably requires a holistic multidisciplinary approach. This review aimed to evaluate the latest evidence in performing FP in pediatric patients with KS, and discuss the controversy surrounding such practice. Hormonal changes in patients with KS during childhood and the use of hormonal manipulation to optimize SSR in this population have also been reviewed.
