ABSTRACT

Purpose: There is a scarcity of literature examining changes in radiologist research productivity during the COVID-19 pandemic. The current study aimed to investigate changes in academic productivity as measured by publication volume before and during the COVID-19 pandemic. Method(s): This single-center, retrospective cohort study included the publication data of 216 researchers consisting of associate professors, assistant professors, and professors of radiology. Wilcoxon's signed-rank test was used to identify changes in publication volume between the 1-year-long defined prepandemic period (publications between May 1, 2019, and April 30, 2020) and COVID-19 pandemic period (May 1, 2020, to April 30, 2021). Result(s): There was a significantly increased mean annual volume of publications in the pandemic period (5.98, SD = 7.28) compared with the prepandemic period (4.98, SD = 5.53) (z = -2.819, P = .005). Subset analysis demonstrated a similar (17.4%) increase in publication volume for male researchers when comparing the mean annual prepandemic publications (5.10, SD = 5.79) compared with the pandemic period (5.99, SD = 7.60) (z = -2.369, P = .018). No statistically significant changes were found in similar analyses with the female subset. Discussion(s): Significant increases in radiologist publication volume were found during the COVID-19 pandemic compared with the year before. Changes may reflect an overall increase in academic productivity in response to clinical and imaging volume ramp down. Copyright © 2022 American College of Radiology

ABSTRACT

Learning outcomes: This case provides detailed information about digital technologies and business practices that may help offline retailers catch up with the trend of new retail. After studying the case and working on the assignment questions, students will be able to:▪ Understand new features of smart cash registers, including facial-recognition payment, purchase-sales-inventory management, customer profile and store management, which all are important for the long-term development of the retail business in the age of "new retail”.▪ Identify opportunities, practices and impacts of digital technologies, such as big data and artificial intelligence, on contemporary retail businesses.▪ Identify problems of traditional retail and suggest solutions by applying the concepts and tools learned above.▪ Apply digital marketing approaches and tools (e.g., social media, livestreaming and online word-of-mouth) to design marketing campaigns;students should include basic elements such as the 6Ms for effective marketing communications (market, mission, message, media, money and measure). Case overview/synopsis: This case describes difficult situations facing Leo Shoudong Pan, the founder and CEO of Yun Dong Jia Technologies Co Ltd (YDJ), in marketing communications. With a motto of "Making it easy to open stores anywhere”, YDJ develops and sells smart cash registers, which provide a self-developed operating system and cloud computing services. Pan targets small and micro retailers, who are technology laggards when digital transitions had swept the world. His goal is to build a network of 100,000 pieces of smart cash registers across China, but he has only sold 8,000 pieces since he founded YDJ in 2016. He must make a breakthrough in the business. To drive leads and sales, he feels the urgency of conducting effective marketing communications with target customers and enhance their understanding on the value that YDJ creates for them. Monetary incentives are tangible but not yet fully demonstrated YDJ's value. With the traditional retail approach, brick-and-mortar stores, especially those small-scaled ones, are not able to meet the market change;instead, they must adopt digital techniques to catch up with the trend of new retail, which is necessary for a long-term business development rather than just a temporary measure during the Covid-19 pandemic. Pan must craft more compelling messages. What customer value should be chosen as incentives to motivate the target market? How to conduct effective marketing communications correspondingly?

ABSTRACT

The coronavirus disease 2019 public health emergency (PHE) caused extensive job loss and loss of employer-sponsored insurance. State Medicaid programs experienced a related increase in enrollment during the PHE. However, the composition of enrollment and enrollee changes during the pandemic is unknown. This study examined changes in Medicaid enrollment and population characteristics during the PHE. A retrospective study documenting changes in Medicaid new enrollment and disenrollment, and enrollee characteristics between March and October 2020 compared to the same time in 2019 using full-state Medicaid populations from 6 states of a wide geographical region. The primary outcomes were Medicaid enrollment and disenrollment during the PHE. New enrollment included persons enrolled in Medicaid between March and October 2020 who were not enrolled in January or February, 2020. Disenrollment included persons who were enrolled in March of 2020 but not enrolled in October 2020. The study included 8.50 million Medicaid enrollees in 2020 and 8.46 million in 2019. Overall, enrollment increased by 13.0% (1.19 million) in the selected states during the PHE compared to 2019. New enrollment accounted for 24.9% of the relative increase, while the remaining 75.1% was due to disenrollment. A larger proportion of new enrollment in 2020 was among adults aged 27 to 44 (28.3% vs 23.6%), Hispanics (34.3% vs 32.5%) and in the financial needy (44.0% vs 39.0%) category compared to 2019. Disenrollment included a larger proportion of older adults (26.1% vs 8.1%) and non-Hispanics (70.3% vs 66.4%) than in 2019. Medicaid enrollment grew considerably during the PHE, and most enrollment growth was attributed to decreases in disenrollment rather than increases in new enrollment. Our results highlight the impact of coronavirus disease 2019 on state health programs and can guide federal and state budgetary planning once the PHE ends.

ABSTRACT

In this prospective study, universal admission testing for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) averted transmission in shared patient rooms especially since the emergence of the SARS-CoV-2 omicron variant when the yield in identifying infectious asymptomatic cases more than doubled. This change may be due to the higher rate of asymptomatic infection with the omicron variant, the broader community prevalence during the omicron era, or both.

ABSTRACT

INTRODUCTION: Data on the associations of pre-pandemic physical activity and sedentary behavior with SARS-CoV-2 infection and Coronavirus Disease 2019 (COVID-19) severity, particularly milder illness, have been limited. METHODS: We used data from 43,913 participants within the Nurses' Health Study II and Health Professionals Follow-Up Study who responded to periodic COVID-related surveys from May 2020 through March 2021. History of physical activity from the pre-pandemic period was assessed as the metabolic equivalents of task (MET)-hours/week of various activities of different intensity and sedentary behavior assessed from reports of time spent sitting from questionnaires completed 2016-2017. Multivariable logistic regression models were fitted to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) for risk of SARS-CoV-2 infection and COVID-19 severity, as well as predicted COVID-19 defined using a validated symptom-based algorithm. RESULTS: Higher levels of pre-pandemic physical activity were associated with a lower risk for SARS-CoV-2 infection. Compared to participants with <3 MET-hours/week, the multivariable-adjusted OR was 0.86 (95% CI:0.74, 0.99;P-trend=0.07) for those with ≥27 MET-hours/week. Higher physical activity levels were also associated with lower risk of symptomatic SARS-CoV-2 infection (OR:0.84;95% CI:0.72, 0.99;P-trend=0.05) and predicted COVID-19 (OR:0.87;95% CI:0.78, 0.97;P-trend=0.01). Longer time sitting at home watching TV (OR:0.85;95% CI:0.73, 0.97) or for other tasks (OR:0.78;95% CI:0.66, 0.92) was associated with a lower risk of SARS-CoV-2 infection. CONCLUSIONS: Our findings support a protective association between pre-pandemic physical activity and lower risk and severity of COVID-19.

ABSTRACT

With the growing popularity of design thinking capacity building initiatives for entrepreneurship education, educators are striving to explore technology-supported learning environments and pedagogy to achieve the inter-disciplinary, easily accessible, and student-oriented entrepreneurship education innovation. The lingering effects of unfinished learning amid the COVID-19 and mixed-mode learning have become part of a new normal, we designed and implemented a novel learning framework to put co-design pedagogical structures in place that allow educators, students, and stakeholders to form new learning experiences and create innovation together. Through the case study we designed and implemented in three universities across different regions, we propose and investigate an approach that enables micro-level analysis of knowledge creation model for student's design thinking capacity building as well as macro-level understanding of learning dynamics for entrepreneurship education. This study presents a pedagogy-based template, and the findings have implications for the design of technology-empowered educational interventions and pedagogical innovation. © ISLS.

ABSTRACT

The novel Coronavirus disease of 2019 had an acutely catastrophic effect on almost every tier of emergency medical services in the United States. The Pro Bono EMS Pandemic Response Research Lab led the national effort into the investigation of prehospital pandemic response in the US mainland, interrogating key systemic issues, infectious disease best practices, and provider safety. This chapter - led by Adj. Prof. Christian Ventura, the Co-Principal Investigator of the lab and adjunct lecturer in prehospital resuscitation science and colleagues - serves as a retrospective analysis into how EMS responded to the global pandemic in the critical year of 2020, what we did right, what we can learn, and implications for the urgently warranted paradigm shifts EMS must consider adopting to prevent infrastructural collapse. © 2021 by Nova Science Publishers, Inc.

ABSTRACT

Aims: The ongoing uncertaintyofThe COVID-19 pandemic and recovery to re-establish elective services presents a major challenge to The NHS. Patient flow and bed capacity is now a priority for acute hospitals. We have implemented a new service model aimed at improving patient flow from A&E, where acute surgical patients are triaged and referred directly to The Advanced Nurse Practitioner (ANp) team for assessment and management. A criterion based on The presenting complaint and clinical observations was developed to identify suitable patients. The utilisation of this service was audited for its safety and impact on The Emergency General Surgical provision. Method(s): The setting is a busy University Teaching Hospital with a diverse catchment population of 75,000. A prospective audit identified The number of patients utilising The new care pathway and details of any adverse events or delays in treatment identified. All patients presenting with a General Surgical condition were included. Result(s): Between August and December 2021, 361 patients were referred directly from A&E (81% within first 2 hours of presentation) to The surgical ANp team for assessment. of these, 85 (24%) were admitted for Emergency treatment and 276 (76%) were discharged The same day for either ambulatory or outpatient follow-up, or back to Primary Care. There were no adverse events identified during The audit period. Conclusion(s): Direct streaming of acute surgical patients within a defined criteria to an ANp-led service is safe and effective in helping to improve patient flow and experience within an acute care model.

ABSTRACT

Introduction: The COVID-19 pandemic has significantly changed outpatient clinic services which now involve virtual (telephone/video) rather than face-to-face consultations. For both new clinic patients or follow-up patients after a recent emergency admission, these changes may impact on their perceptions and confidence in The outpatient service. The aim of this service provision audit is to ascertain both patient satisfaction and confidence in virtual consultations in our unit. Method(s): A retrospective evaluation of all General Surgery virtual clinic appointments between January and March 2021 was undertaken. Patients were contacted for feedback about their surgical consultation based on questions from The National Health Service Outpatient Department Survey (2011). Result(s): In total, 151 patients were contacted. Overall satisfaction regarding telephone consultations was significantly higher when compared to survey results of face-to-face appointments in The pre-COVID era. The majority of patients were confident (51%) or confident to some extent (27%) of being listed for Surgery without further examination. only 8% of patients were not confident at The way Surgery was explained and 10% were not confident of The risks of surgery. Finally, more than a third were not happy to be discharged from clinic following a telephone consultation. Conclusion(s): Follow-up appointments are an integral part of The patient journey following an emergency admission. The COVID-19 recovery phase has necessitated a service reconfiguration towards virtual appointments. We show that patients were satisfied with virtual consultations, although further quality improvement should be undertaken to ensure outpatient discharge is satisfactory for all patients following an emergency admission.

ABSTRACT

Aims: Over 65,000 cholecystectomies are performed each year in The United Kingdom with increasing waiting-list times due to The CoVID-19 pandemic. This study set out to understand The cost to The NHS of complications experienced whilst awaiting cholecystectomy. Method(s): A retrospective cohort study was carried out for all patients who had been awaiting elective cholecystectomy for more than 20 weeks On The 17th September 2021 at a large NHS Foundation Trust. Demographic data was collected at The time of listing. Re-admission data was collected from patient notes. It included clinical history, blood results and imaging investigations. Associated costs were calculated. Result(s): 900 patients included in The study (median age 56 years, 71.7% female). 138 patients (15.3%) re-presented to hospital whilst On The waiting list with complications of gallstone disease. Of these, 51 had more than one presentation to hospital with 18 patients having more than three presentations. This was equivalent to 625 days in hospital, with only 79 same day discharges, and multiple investigations were performed (ultrasound scan = 79;CT scan = 31, MRCp = 47, ERCp = 21). This was estimated to have cost a minimum of 364,917. Assuming an average time for an elective cholecystectomy of 90 mins at a cost of 1,200 per hour, 202 additional cholecystectomies could have been performed. Conclusion(s): This study highlights The enormous potential to reduce patient suffering by increasing The number of elective cholecystectomy lists, and at no overall additional cost to The trust.

ABSTRACT

Introduction: In response to the COVID-19 pandemic, the World Society of Pediatric Ophthalmology and Strabismus (WSPOS) piloted strabismus surgery simulation webinars providing real-time surgical instruction using an accessible model eye. The purpose of this study was to demonstrate improvement in confidence level with strabismus surgery among ophthalmology residents who participated in the webinar. Method(s): Five strabismus surgeons (from 5 different countries) taught 10 beginning ophthalmology residents (from 5 different countries) using a homemade model eye and a cell phone streaming the surgical view. Surgical techniques taught included needle handling, scleral passes, and suturing extraocular muscles. Residents watched a video demonstrating techniques prior to the webinar. Three surveys completed Pre-Video, Post-Video, and Post-Webinar evaluated comfort level in surgical skills using Likert scales. Survey responses were analyzed using paired t tests and repeated measures ANOVA (SPSS v24). Queen's University Health Sciences Research Ethics Board approval was obtained. Result(s): Nine of 10 trainees answered the surveys: 66% were 25-29 years old;62.5% were second-year residents. Paired t test showed a statistically significant increase in comfort level in performing scleral passes, suturing an extraocular muscle, and creating a locking bite at the muscle pole between Pre-Video to Post-Webinar surveys (P < 0.05). Exploratory repeated measures ANOVA revealed improvements in scores for 4 of the 5 questions (P < 0.05). Conclusion/Relevance: Our pilot study demonstrates effective teaching of strabismus surgery techniques virtually using an accessible model eye. Virtual teaching allows delivery of world expertise teaching to trainees worldwide, diminishing barriers to learning and improving eye care to patients globally. Copyright © 2022

ABSTRACT

This study investigates the transport of air pollutants around the Yangtze River Delta with an aim to identify if there would be a relationship towards health effects during the COVID-19 lockdown period. It is well-known that due to lockdown, the number of socio-economical activities are reduced and hence there is an observable reduction in air pollution. We would like to investigate if this consequential reduction of air pollution would lead to improvement in health amongst its population. A number of integrated methodologies are utilized, including collection and correlation of statistical data and numerical modeling to correlate the mortality rates difference with and without COVID-19 lockdown. In particular air quality changes during the COVID-19 lockdown period are compared with similar periods of the previous years using Brute Force Method. It is found that in general there is significant reduction in air-pollution related mortality, like stroke, ischemic cardio diseases, obstructive pulmonary disease, lung cancer and acute lower respiratory infection are all reduced as a result of relative improvement in PM2.5 level during the lockdown period. Further investigation of the trajectories suggests that these PM2.5 originate from afar with multiple sources, and do not suggest COVID-19 are transported to the region via long-range transport. Our results demonstrate the need for more stringent policy measure to tackle air pollution as it has strong evidence that it increases mortality rate. © 2022 Elsevier Inc. All rights reserved.

ABSTRACT

Introduction: Viral upper respiratory tract infections (URTI) such as respiratory syncytial virus, rhinoenterovirus coronavirus, and others are common in children, and they can have serious effects on the pediatric airway. The literature is limited on how often ear, nose, and throat (ENT) clinician involvement is required in patients admitted with a URTI. This project aims to characterize and identify factors associated with ENT involvement in care of pediatric patients with positive respiratory virus panels (RVP) and if any require airway interventions. Method(s): A retrospective study was conducted collecting information on patient demographics, comorbidities, course of treatment, incidence of ENT consultation, and incidence of airway interventions (flexible laryngoscopy, intubation, tracheostomy, direct laryngoscopy, etc) for all pediatric patients with a positive RVP who were treated either inpatient or in the emergency department from January 2018 to January 2020 at a tertiary care academic facility. Result(s): A total of 1019 of 1317 consecutive charts with a positive RVP over a 2-year period were reviewed. Preliminary result analysis was completed for the 1019 completed charts. Twenty-eight patients (2.7%) required an ENT consultation. Congenital birth defects were significantly associated with ENT consultation (odds ratio [OR]=3.75;P=.001). Length of stay was significantly associated with higher rate of ENT consultation per day of stay (OR=1.07 per day of stay;P<.001). All other factors studied were not significantly associated with higher rate of ENT consult. Conclusion(s): The incidence of ENT consultation in inpatients with URTIs is relatively uncommon. The preliminary data of this study suggest congenital birth defects and longer length of stay could be used as potential markers to help identify patients who may be at increased risk for worse airway outcomes and need for further airway intervention.

ABSTRACT

Purpose: The demand for kidney transplant continues to rise, and limited supply has encouraged acceptance of marginal donor organs, such as those at risk for acute kidney injury (AKI). We evaluated the utilization of such organs (defined as donation after cardiac death, pediatric donors, kidneys with a cold ischemic time >24 hrs, terminal serum creatinine (SCr) >2mg/dL or rising SCr with decreasing urine output at donation) at our center who were discharged on belatacept based maintenance immunosuppression with mycophenolate and steroids (BBMS). Method(s): This retrospective, descriptive study examined kidney transplant recipients (KTR) who received AKI organs and were discharged on BBMS between 1/2019-4/2021. Primary outcome assessed graft function and rejection at 6 & 12 months (mos) post-transplant (txp). Secondary outcomes evaluated graft failure, mortality, infection, DSA & changes to BBMS. All outcomes were evaluated at 1yr if records were available. Result(s): 68 KTR w/1 yr results & 52 w/6 mo results on BBMS were included. Baseline characteristics (Table 1) show most KTR received a DCD or en bloc organ and lymphocyte depleting induction. Mean eGFR improved from 1 to 6 mo post-txp and was stable through 1yr. Episodes of biopsy proven rejection were more common during the first 6mos post-txp. There were 2 deaths during the study period, due to COVID, and no graft failures. Twelve KTR developed DSA. There were 21 KTR with CMV viremia, mostly in moderate risk group, & 12 with BK viremia. Table 4 shows changes to BBMS occurred in 32 KTR. Most KTR required multiple BBMS changes with most common dose adjustments to mycophenolate due to leukopenia or neutropenia. Conclusion(s): Utilization of AKI organs with BBMS in KTR at our center resulted in no graft failures & sustained eGFR despite more rejection episodes during the first 6mos post-txp. Although 32 KTR had changes to BBMS, only 5 KTR had rejection following a change. Incidence of CMV was common but did not impact KTR outcomes. Overall, BBMS could be a promising option in AKI organs to avoid nephrotoxicity associated with CNI based regimens. These findings suggest the need to further evaluate the impact of long-term outcomes associated with changes made to BBMS in AKI donor organs.

ABSTRACT

Objective: To describe the evolution of respiratory antibiotic prescribing during the coronavirus disease 2019 (COVID-19) pandemic across 3 large hospitals that maintained antimicrobial stewardship services throughout the pandemic. Design: Retrospective interrupted time-series analysis. Setting: A multicenter study was conducted including medical and intensive care units (ICUs) from 3 hospitals within a Canadian epicenter for COVID-19. Methods: Interrupted time-series analysis was used to analyze rates of respiratory antibiotic utilization measured in days of therapy per 1,000 patient days (DOT/1,000 PD) in medical units and ICUs. Each of the first 3 waves of the pandemic were compared to the baseline. Results: Within the medical units, use of respiratory antibiotics increased during the first wave of the pandemic (rate ratio [RR], 1.76;95% CI, 1.38-2.25) but returned to the baseline in waves 2 and 3 despite more COVID-19 admissions. In ICU, the use of respiratory antibiotics increased in wave 1 (RR, 1.30;95% CI, 1.16-1.46) and wave 2 of the pandemic (RR, 1.21;95% CI, 1.11-1.33) and returned to the baseline in the third wave, which had the most COVID-19 admissions. Conclusions: After an initial surge in respiratory antibiotic prescribing, we observed the normalization of prescribing trends at 3 large hospitals throughout the COVID-19 pandemic. This trend may have been due to the timely generation of new research and guidelines developed with frontline clinicians, allowing for the active application of new research to clinical practice. © The Author(s), 2022.
