Preconceived Impressions Regarding Holmium:YAG Laser Safety in the Urology Operating Theatre.

Background: Since its introduction over two decades ago, the surgical laser has served in the lithotripsy of urinary calculi, resection of bladder tumours, bladder neck incisions, and prostate enucleation. Concerns regarding the safe use of holmium lasers have resulted in potentially excessive and overly precautious theatre regulations. We aimed to evaluate the preconceived impressions and practice patterns at a single site surrounding laser use in endourology. Methods: We designed a three-part online questionnaire that could be accessed using a smart device or computer. This survey was distributed to all theatre staff involved in laser surgery at our single site, including surgical, nursing, and anaesthetic staff of varying seniority. It asked questions regarding holmium laser safety, provided an up-to-date summary of published literature surrounding the safe use of lasers, and finally gave participants further option to alter the answers to several previously encountered questions. Results: A total of 54 theatre staff completed the survey, including 17 theatre nurses (31.5%), 10 urology consultants (18.5%), 8 urology registrars (14.8%), 7 anaesthetic registrars (13%), 4 anaesthetic consultants (7.4%). About 51.9% of participants believed that current laser safety protocols were adequate, with 38.9% finding them excessive. After reading recently published information on laser safety, 22.2% thought current laser safety measures were adequate (57% decrease) and 77.8% found them to be excessive (100% increase). About 74.1% of participants found that laser safety goggles impair their vision and that 79.6% would choose not to wear them if they were optional. Conclusion: Strict laser safety guidelines reflect an overestimated risk associated with using holmium laser in operating theatres. Laser safety regulations should be re-evaluated to align with current research and potential hazards inherent to the device. In doing so, a more effective distribution of staff could enable greater access to laser surgery, thereby reducing patient morbidity and hospital wait times.

Integration of an online application to optimise multi-disciplinary meetings: a retrospective analysis.

BACKGROUND: Multi-disciplinary Meetings (MDM) play a crucial role in complex patient care, involving input from various specialties to formulate evidence-based management plans. However, traditional unidirectional approaches and reliance on manual processes have led to inefficiencies in the MDM pathway. AIMS: This study identified and aimed to improve four critical moments where Information Communication Technologies (ICTs) could enhance the MDM process. Initial referral, information synthesis, meeting presentation and the creation of actionable/auditable items. METHODS: Microsoft Office Forms, a customisable survey platform, was implemented to streamline MDM processes. Forms were created to gather patient information, develop agendas, and track outcomes. Automation through Excel scripting further optimised data organisation and agenda creation. RESULTS: Referrals using Forms takes an average of 7 min and 21 s. Over 15 months the submission time has reduced and is trending towards under 5 min for each referral. The system's scalability has allowed 1744 cases to be discussed over a 15-month period. Active departments using Forms is expanding to seven from two prior to the pilot. CONCLUSION(S): Microsoft Office Forms proved to be a valuable and adaptable tool for MDMs, offering benefits such as streamlined information gathering, real-time collaboration, and scalability. The study highlights the potential of existing tools within Microsoft licenses for healthcare process optimisation, providing a cost-effective and customisable solution for MDM agendas. While recognising some limitations, the study concludes that leveraging Microsoft Office Forms can significantly improve system efficiency in a multi-disciplinary setting.

Molecular analysis of primary and metastatic sites in patients with renal cell carcinoma.

BACKGROUNDMetastases are the hallmark of lethal cancer, though underlying mechanisms that drive metastatic spread to specific organs remain poorly understood. Renal cell carcinoma (RCC) is known to have distinct sites of metastases, with lung, bone, liver, and lymph nodes being more common than brain, gastrointestinal tract, and endocrine glands. Previous studies have shown varying clinical behavior and prognosis associated with the site of metastatic spread; however, little is known about the molecular underpinnings that contribute to the differential outcomes observed by the site of metastasis.METHODSWe analyzed primary renal tumors and tumors derived from metastatic sites to comprehensively characterize genomic and transcriptomic features of tumor cells as well as to evaluate the tumor microenvironment at both sites.RESULTSWe included a total of 657 tumor samples (340 from the primary site [kidney] and 317 from various sites of metastasis). We show distinct genomic alterations, transcriptomic signatures, and immune and stromal tumor microenvironments across metastatic sites in a large cohort of patients with RCC.CONCLUSIONWe demonstrate significant heterogeneity among primary tumors and metastatic sites and elucidate the complex interplay between tumor cells and the extrinsic tumor microenvironment that is vital for developing effective anticancer therapies.
