The Application of Biosensors in the Detection of SARS-CoV-2

Since the outbreak of COVID-19, it is becoming important to screen SARS-CoV-2 with high accuracy, high efficiency, and rapidness, for epidemic prevention and control. Conventional detection technologies can not satisfy the requirements of examining massive people in a very short time. Biosensor technology, with the advantages of high sensitivity, good selectivity, low cost, easy miniaturization, and short detection time, is being used to develop real-time detection equipment, thus as a potential alternative for real-time detection of SARS-CoV-2 in clinical diagnosis. In the present study, the authors summarized the construction methods and principles for optical biosensors, electrochemical biosensors, wearable biosensors, magnetic biosensors, gold nanoparticle biosensors, and aptamer biosensors, followed by the introduction of the current application of multiple biosensors in SARS-CoV-2 detection. Conclusively, the technical bottlenecks and future development trends of biosensors in SARS-CoV-2 detection are proposed.

FELLOW EXPERIENCES WITH ENDOSCOPY SIMULATION BEFORE AND DURING THE COVID-19 PANDEMIC: AN INTERNATIONAL SURVEY

Background With the COVID-19 pandemic there was an acute drop in procedural volume for trainees, highlighting the need and potential of simulation-based training (SBT). Prior to the pandemic, the uptake of simulation was poorly categorized and inconsistent across programs despite the variety of endoscopic simulators available. We aimed to evaluate the current state of endoscopy training internationally in the wake of the pandemic as perceived by trainees. Methods This cross-sectional study utilized a survey composed of 21 questions eliciting demographic data, COVID-19-related training experiences, and experience with SBT. This survey was distributed internationally (USA, Canada, EU, Philippines, Singapore) to gastroenterology trainees between August 2021 to October 2021. Results The questionnaire was completed by 182 fellows, with 55 (30.2%) from the USA and 127 (69.8%) from other countries. Of the respondents, 79.1% were fellows during the first year of the pandemic. A majority (69.2%) found endoscopy training in general to be negatively impacted. Of those who reported a negative impact from the pandemic, 75.0% attributed it to a decline in endoscopic volume, 40.0% to institutional/regional guidelines, 25.0% to a shortage of personal protective equipment. Overall, 47.2% of respondents believed COVID-19 will negatively affect their endoscopic proficiency upon fellowship completion. A total of 71 respondents (39.0%) had experienced SBT before or during fellowship, with 27 from the USA (49.1% of respondents from USA) and 44 from other countries (34.6% of respondents from other countries). In the USA, 63.0% had used virtual reality (VR), 37.0% mechanical models, and 37.0% animal models compared to 47.7% VR, 68.2% mechanical models, and 27.3% animal models in other countries. Respondents agreed that SBT was most helpful with developing technical skills such as ergonomic handling, torque steering, and fine tip control. A majority (52.1%) found SBT appropriate to their level of training. Respondents believed increased access to SBT (43.7%) and mentored training (54.9%) would improve the experience. Conclusion While current data supports the use of SBT early in training, the cumulative uptake of SBT across programs before and during the COVID-19 pandemic remained low. In the USA and abroad, fellows perceive a negative impact of COVID-19 on their training and proficiency upon graduation. Compared to other countries, the USA had higher utilization of VR and lower utilization of mechanical models. Decrease in endoscopic volume was reported as the main factor negatively impacting endoscopic training. This survey highlights the potential benefit of SBT with low case volumes and further prospective evaluation of SBT in achieving endoscopic competence. (Table Presented)

Providing and Accessing Support during the COVID-19 Pandemic: Experiences of Mental Health Professionals, Community and Vocational Support Providers, and Adults with ASD

Due to the COVID-19 pandemic, essential services and support for individuals with ASD have had to transition to telehealth and virtual technologies. While these technologies have been recommended for use to continue provision of essential services to this population, it has yet to be understood what impact it has had on essential service providers and adults with ASD. This experience report provides insight from essential service providers and adults with ASD from a community center for adults with developmental disabilities to understand their experiences in providing and accessing mental health, and community and vocational support during the COVID-19 pandemic through telehealth and virtual technologies. © 2021 Owner/Author.
