Article Abstract
: Improvements in catheter connection design intended to increase safety have resulted in connections that are difficult to release manually. No medical device exists to safely disconnect catheter connections. Nurses and other users have developed workarounds including use of hemostats, tourniquets, and wrenches. These workarounds are not always successful for performing this task and can break catheters and catheter connections. This study aimed to evaluate a disconnection device to safely disconnect catheter connections. : This is a mixed-methods study using a user-centered design approach with triangulation of quantitative and qualitative data mapped to Valdez's sociotechnical framework. Nurses ( = 139) from units across two academic medical centers encompassing diverse patient populations engaged in usability testing and surveys. Data about users' past catheter disconnection experiences and usability of the specialized disconnection device were collected and analyzed. Triangulation of quantitative data and qualitative themes was mapped using Valdez's socio-technical framework to complement and strengthen the final design generated for nurses' user requirements. : Ninety-five percent of nurses reported previous difficulty with disconnecting luer connections; 93% of those reporting difficulty improvised with readily available medical devices or products to better grip the connected parts. Over 85% of nurses reported positive experiences using the specialized disconnection device; others suggested design improvements for better performance. : The nurses who tested the developed disconnection device reported high acceptability, accessibility, ease of use, and improved task performance. Moreover, as workarounds develop at points of practice where no systematic solution exists, aiming product development activities at these points help close gaps in achieving and maintaining patient safety. This study was not registered.

Looking beyond digital broadband speeds: Rural British Columbian's experiences with internet connectivity as a basic necessity.
PLoS One

Department of Computer Science, Mathematics, Physics and Statistics, University of British Columbia, Okanagan Campus, Kelowna, British Columbia, Canada.
Aim: This study examined the experience of digital connectivity among rural-living British Columbians both with and without access to high-speed Internet at home.
Background: Evidence indicates that fewer rural communities have access to high-speed Internet compared to urban communities in Canada, despite government commitments to bring high-speed Internet to all British Columbians by 2027. Yet, differences within rural areas relative to those with access to high-speed compared to those with lower speeds remains a relatively unexplored area.
Robotics in Orthopaedics: Exploring Future Possibilities for South Africa.

This editorial examines the feasibility and ethical implications of integrating robotic-assisted orthopaedic surgery into South Africa's healthcare system. While such technologies are well-established in high-income settings, enhancing surgical precision, reproducibility and postoperative outcomes, their widespread adoption in resource-limited contexts poses considerable logistical, financial and ethical challenges. The South African health landscape, marked by stark disparities between public and private sectors, provides a unique setting in which to assess whether such innovations should be prioritised over more pressing service delivery needs.

In modern power systems, it is crucial to monitor and detect internal faults in power transformers promptly and accurately to ensure reliability and prevent disruptions. Failure to identify these faults promptly can reduce the transformer's lifespan, cause system disconnection, and compromise network stability. This paper introduces an innovative method for the discrimination, classification, and localization of internal short-circuit faults in power transformers, with a focus on three types of winding faults: turn-to-turn fault, series short circuits, and shunt short circuits.

Background: The Versius surgical system (CMR Surgical, Cambridge, UK) is a new robotic platform introduced after the original patent of the DaVinci system expired; it has already been applied in different fields, including gynaecology. Unlike DaVinci, Versius has four independent bedside units (BSU), which must be individually positioned with adequate angles and distance to avoid collisions. Given this peculiarity and the shorter arm (30 cm) compared to the Da Vinci, investigating BSU positioning and port placement is mandatory.

Endoscopic ultrasound (EUS)-guided drainage using lumen-apposing metal stents (LAMSs) has become the standard for managing pancreatic fluid collections (PFCs), especially walled-off necrosis (WON). However, LAMS-specific adverse events (AEs), including bleeding, stent occlusion, and infection, remain a concern. To mitigate these complications, some experts advocate placing coaxial double-pigtail plastic stents (DPPSs) within LAMSs.
