How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

A new approach for Total Ionizing Dose effect analysis on Flash-based FPGA

With the high flexibility, increasing computing power and lower power consumption, FPGA devices have gained a lot interest in space and avionic applications. Among different types of FPGA devices, Flash-based FPGA is becoming increasingly attractive since their configuration memory is almost immune to Single Event Upset (SEU) induced by energetic particles. However, when applied in such applications, especially long term space missions, the FPGA devices are subject to cumulative ionizing damage, as known as Total Ionizing Dose (TID). The TID may affect the FPGA causing performance degradation and possible eventual permanent damage leading to functional failure. In this paper, we propose a new workflow for analyzing the TID effect on Flash-based FPGA considering the different distributions of TID over the chip and the different impact factors when the configurable logic is programmed to implement different logics in the design. The experimental results show the feasibility of such workflow to be used as assessment tool at early stage of design development
