Clinical Significance of Extracellular Vesicles in Prostate and Renal Cancer. Int J Mol Sci 2023; 24:14713. [PMID: 37834162 PMCID: PMC10573190 DOI: 10.3390/ijms241914713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 09/02/2023] [Accepted: 09/03/2023] [Indexed: 10/15/2023] Open
Abstract
Extracellular vesicles (EVs)-including apoptotic bodies, microvesicles, and exosomes-are released by almost all cell types and contain molecular footprints from their cell of origin, including lipids, proteins, metabolites, RNA, and DNA. They have been successfully isolated from blood, urine, semen, and other body fluids. In this review, we discuss the current understanding of the predictive value of EVs in prostate and renal cancer. We also describe the findings supporting the use of EVs from liquid biopsies in stratifying high-risk prostate/kidney cancer and advanced disease, such as castration-resistant (CRPC) and neuroendocrine prostate cancer (NEPC) as well as metastatic renal cell carcinoma (RCC). Assays based on EVs isolated from urine and blood have the potential to serve as highly sensitive diagnostic studies as well as predictive measures of tumor recurrence in patients with prostate and renal cancers. Overall, we discuss the biogenesis, isolation, liquid-biopsy, and therapeutic applications of EVs in CRPC, NEPC, and RCC.

[PMID: 36700355 PMCID: PMC10039792 DOI: 10.1002/ueg2.12355] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Accepted: 12/07/2022] [Indexed: 01/27/2023] Open
Abstract
The SARS-Cov-2 disease disrupted essential hospital procedures, such as gastrointestinal (GI) endoscopy, due to concerns about air transmission and the risk of exposing health care workers. With the spread of the pandemic, air transmission was considered as the main source of SARS-Cov2 transmission. This raised the problem of transmission by aerosolization of viral particles in operating rooms as well as endoscopy units. This is in line with the known airborne transmission of many other respiratory viruses. The risk of SARS-Cov-2 transmission during GI endoscopy was initially reduced by controlled measures, involving personal protections (mask…), restricted access to endoscopy rooms, and detection of infected patients. Gastrointestinal endoscopy generates aerosols, which may carry viruses. In addition, the endoscopy system may facilitate the diffusion of virus particles or fomites considering the forced-air cooling system used to maintain a stable temperature inside the box (25°C). The volume of air that goes through the light source box is high (240-300 m3 for a 1-h period). Moreover, the light system contains an air pump to inflate air inside the gut lumen. In order to isolate people from hazard, different levels of protection and solutions to avoid airborne transmission of microorganisms should be proposed, such as the reinforcement of personal protective equipment, the change in the way people work and engineering control of the risk.

Impact of COVID-19 on Society of Urologic Oncology fellowship operative volumes. Urol Oncol 2022; 40:490.e7-490.e11. [PMID: 36182615 PMCID: PMC9452401 DOI: 10.1016/j.urolonc.2022.09.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 08/17/2022] [Accepted: 09/01/2022] [Indexed: 11/24/2022]
Abstract
Purpose The COVID-19 pandemic impacted all aspects of healthcare including surgical training. Our objective was to assess the impact of the pandemic on surgical case volumes of graduating Society of Urologic Oncology (SUO) fellows during the academic years 2019 to 2020 and 2020 to 2021. Materials and methods Deidentified case logs for graduating SUO fellows from 2017 to 2021 were obtained from the SUO Education Committee. Cases are stratified by category and minimally invasive surgery (MIS) or open approach. Graduates of 2017, 2018, and 2019 were combined into a pre-COVID cohort and compared to COVID-affected 2020 and 2021 cohorts. Total case volumes, case category volumes, and surgical approach type were compared with Kruskal-Wallis test. Results A total of 173 graduating SUO fellow case logs were analyzed with 100, 38, and 35 in the pre-COVID and COVID-affected 2020 and 2021 cohorts, respectively. All fellow logs were obtained for 2017 to 2020 graduates while 5 of 40 were missing for the 2021 cohort. There was no statistical difference in median total cases across cohorts (P = 0.52). For the first COVID-affected cohort of 2020, they reported significantly fewer total MIS cases in 2020 compared to pre-COVID fellows (median 92.5 vs. 135 pre-COVID, P = 0.002). However, there were no significant differences among the tracked oncologic MIS categories except a statistically significant increase in MIS retroperitoneal lymph node dissection between 2020 and 2021 COVID-affected cohorts (0 vs. 2, P = 0.033) Conclusions The oncologic case volumes of the initial SUO fellows graduating during COVID pandemic were minimally affected. This national deidentified data is reassuring that oncologic training has not been impacted by widespread decreases in case volume. However, impacts on individuals, programs or geographic regions may have varied.

Abstract
With over 4.8 million deaths within 2 years, time is of the essence in combating COVID-19. The infection now shows devastating impacts on the younger population, who were not previously predicted to be vulnerable, such as in the older population. COVID-19-related complications have been reported in neonates whose mothers were infected with SARS-CoV-2 during pregnancy, and in children who get infected. Hence, a deeper understanding of the pathophysiology of COVID-19 during various developmental stages and placental transmission is essential. Although a connection has not yet been established between exosomal trafficking and the placental transmission of COVID-19, reports indicate that SARS-CoV-2 components may be trafficked between cells through exosomes. As the infection spreads, the transcriptome of cells is drastically perturbed, e.g., through the severe upregulation of several immune-related genes. Consequently, a major outcome of COVID-19 is an elevated immune response and the detection of viral RNA transcripts in host tissue. In this direction, this review focuses on SARS-CoV-2 virology, its in utero transmission from infected pregnant mothers to fetuses, SARS-CoV-2 and exosomal cellular trafficking, transcriptomic impacts, and RNA-mediated therapeutics against COVID-19. Future research will establish stronger connections between the above processes to develop diagnostic and therapeutic solutions towards COVID-19 and similar viral outbreaks.
