ABSTRACT

The COVID-19 is putting tremendous pressure on the medical facilities supply, as the demand for facilities has significantly outweighed the production capability. Several rogue traders have taken advantage of this issue to distribute counterfeit products. Moreover, some sellers advertise genuine products with unreasonably high prices. Our team believes that fake or overpriced facilities will significantly complicate the battle against COVID, thereby posing millions of lives to risk. That is why our team is developing V-Block. V-Block is a supply chain management system that harnesses the power of Blockchain. Its primary goals are to assist the government in tracking the product’s distribution process and help customers avoid questionable deals. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

Background: Oncology patients are high users of the emergency department (ED), which often results in hospital admissions for management of cancer symptoms or cancer treatment toxicities. Interventions such as urgent care (UC) models can decrease such visits, and help improve patient management, health care utilization, and patient experience. Sunnybrook Health Sciences Centre, a large tertiary care hospital in Toronto, Canada has a high volume of medical oncology ED visits (average 4 per day) with about 50% admitted for management. Method(s): A novel physician-assistant (PA) led and physician supervised UC model was developed to assist in medical oncology patient phone triage, assessment, and management of cancer or treatment related issues that would otherwise have been sent to the ED by the oncology team. There were two phases: 1) due to COVID, the patients were managed in a dedicated stream primarily using space and nursing in the ED, 2) a dedicated UC clinic with nursing support was opened for these patients. Result(s): In phase 1, there were 424 referrals over 24 months;84% would have otherwise been sent through the usual ED process. 26% of patients were managed with PA navigation outside the UC program in other hospital settings. Of the 204 patients formally treated in the UC stream, 67.7% were discharged home. At 48 hours, 89% of discharged patients were stable or improved;this was 80% at 14 days, and 17.3% came back to the ED or were admitted within 14 days of the UC visit. In phase 2, there have so far been 214 referrals over 5 months;83.6% would have otherwise been sent to the ED. Of the patients who were assessed, 77.9% were discharged home. Outcomes of these patients are being collected. The top 3 patient issues managed during both phases were: fever, pain, and dyspnea. Fifteen patient telephone surveys were completed, and 93.3% were either satisfied or highly satisfied with their UC experience. Conclusion(s): A novel PAled triage and management model for urgent medical oncology patient issues was found in initial phase to be feasible and effective with streamlined care through the ED. Once a dedicated UC clinic was opened, referral volumes increased, and a high rate of ED diversion, patient discharge, and effective care was continued. Patients were also highly satisfied. Several ongoing process and outcome measures are being evaluated to help expand the scope and impact of this resource.

ABSTRACT

BACKGROUND: Since early 2020 systems have been dealing with the impacts of the COVID-19 pandemic, social isolation, and restricted movement of people on access to medications and management services, this poster will describe and assess the capture of adherence outliers into UI TEAM RX an outpatient pharmacy-based patient care delivery model. OBJECTIVE(S): To assess the capture of EQuIPP adherence outlier patients into a pharmacy-based patient care model (UI TEAM RX), days to medication pick up, and improvement in adherence in an outpatient pharmacy during COVID calendar years (CY) 2020 and 2021. METHOD(S): A monthly list of patients who have not met the adherence benchmark is obtained from EQuIPP. These patients are captured within the UI TEAM RX patient care model. Capture rate was defined as the ratio of the total number of patients captured in UI TEAM RX over the total number of potential captures. The total number of potential captures represents the total number of adherence outliers attributed to the pharmacy minus the patients that are captured by other pharmacy-managed services. The average number of days to pick up the medications was quantified as the days gap between medication ready status to pick up by the patient. Improvement in adherence was defined based on whether the patient remained an outlier at the end of the year. RESULT(S): For the outpatient care center pharmacy, 146 and 119 unique EQuIPP adherence outlier patients were identified for CY2020 and 2021, respectively. During the peak of the COVID pandemic in 2020, the capture rate for the model was only 43%. In 2021, the patient capture rate for the model rose to 100%. The average days to pick up were 2.9 and 2.6 for CY 2020 and 2021, respectively. At the end of 2020, five UI TEAM RX patients were no longer outliers vs one patient at the end of CY 2021. The number of Non-UI TEAM RX patients (patients not captured in the model) that remained outliers for CY 2020 and CY 2021 are one and ten. CONCLUSION(S): A lower capture rate was observed during CY 2020, which may be attributed to the start of the pandemic. There was a significant improvement in the capture rate in 2021. The average days to medication pick-up were shorter in 2021 vs 2020. A fewer number of patients remained as outliers at the end of 2021 vs 2020 as well. Engaging patients in the UI TEAM RX model appears to impact achieving adherence benchmarks positively;however, this needs to be further researched appropriately.

ABSTRACT

This study estimates the macro-economic factors affecting the listed small and medium enterprises' capital structures in Vietnam from 2010 to 2020. The author conducts the quantitative method (generalized method of moments—GMM) with valid instrument variables to solve the endogeneity in regression models, which refers to the determinants of capital structures. Based on the trade-off theory and the pecking order theory, the author provides evidence of macro-economic factors and firm-specific factors in explanations for the capital choices of the Vietnamese firms, including national governance, inflation, COVID-19, firm age, and asset structure. In particular, this study highlights how national governance and COVID-19 influence the capital structure of small and medium enterprises in Vietnam. © 2023 by the authors. Licensee ESJ, Italy.

ABSTRACT

This research aimed to investigate the determinants of panic purchasing to hoard food in Ho Chi Minh City during the lockdown caused by the COVID-19 pandemic. Pragma-tism and the deduction approach were used for the research. During the lockdown period in Ho Chi Minh City, the purposive sampling technique was the first method used to reach the popula- tion that needed to be measured. Then, simple sampling was the second technique to collect data in the city in July and August 2021. Data were collected from 584 participants-higher than the required minimum sample size-who fulfilled the essential criteria to be included in the sample's population. Multi-quantitative methods, including descriptive statistics, reliability tests for items, exploratory factor analysis, and linear regression analysis, were used to analyze the data obtained. The main findings are that perceived scarcity, susceptibility, severity, cues to action, and self -ef- ficacy impacted panic purchasing to hoard foods. The results of this study are compared to the literature review in order to discuss panic buying behaviour, and recommendations are offered to policymakers and researchers in the future.

ABSTRACT

Introduction: The American Academy of Ophthalmology's recommendation to provide only urgent/emergent care during the COVID-19 pandemic resulted in high-volume appointment cancellations. We aim to evaluate how the rescheduling process at one academic medical center's pediatric ophthalmology clinic was perceived by caregivers and to identify factors contributing to caregiver satisfaction, attitudes toward alternative appointments, and perception of patient harm. Method(s): Caregivers of children whose pediatric ophthalmology appointment was cancelled during the early pandemic, 3/18-5/18/2020, were recruited via telephone consent to complete an 18-question, 10-point Likert scale, anonymous online survey. Result(s): 110/484(23%) of respondents completed the survey. Most were rescheduled < 7months from the original date (25%- < 4wks, 23%-5wks-3mos, 36%, 4-6 mos, 16%, >7 mos;P = 0.003). Of the ocular diagnoses rescheduled, 41% were low acuity, 50% moderate, and 9% high, which correlated to the length of time to reschedule (57% high acuity, < 4 wks;74% low acuity, >4 mos;P = 0.006). There was no difference in willingness to accept alternative appointments between new (n = 95) versus established (n = 15) patients, (phone call: p = 0.555, audio-visual telemedicine: p = 0.403). Overall frustration with rescheduling was low (mean: 2.61 +/- 2.91) and was higher in those with a longer interval to reschedule (< 4 wks vs >7 mos P = 0.0419, 5wks-3mos vs >7 mos P = 0.019). Perception of harm caused by delay in care was most associated with length of time to reschedule (P = 0.006). Conclusion(s): Overall caregiver frustration toward the rescheduling process was low at one academic medical center's pediatric ophthalmology clinic during the early COVID-19 pandemic. Survey results suggest that more interpersonal methods of patient examination/communication such as audio-visual telemedicine or transfer to another provider were preferred over audio-only telemedicine.

ABSTRACT

In recent years, nontraditional security (NTS) studies have been the focus of growing interest in the security literature. However, this work only focuses on conceptualization and associated risks and makes only limited connections between nontraditional security and sustainability. Furthermore, the United Nations Sustainable Development Goals (SDGs) have been threatened by NTS concerns such as the COVID-19 pandemic. The aim of this article is to contribute to the current debate about NTS and to formulate an integrated approach with sustainable development. We devote attention to sustainability and security studies to understand the challenges and opportunities for achieving sustainable outcomes. To highlight the role of the management of NTS in achieving the SDGs, we review the literature and analyze the main threats of NTS in Vietnam. This article shows that sustainability studies should not be separated from nontraditional issues. By analyzing case studies of NTS threats in Vietnam, we find that the economic, social, and environmental pillars of Vietnam’s sustainable development are threatened despite the country’s great success in economic growth in recent decades. We conclude by noting that the lack of integrated linkages between NTS and sustainability creates obstacles for Vietnam’s sustainable development and nontraditional sources of insecurity pose a serious threat to the development prospects of the country. Therefore, in the context of an integrated approach, countries should incorporate certain aspects of the human-security agenda as nontraditional matters into their national development policies. © 2022 The Author(s).

ABSTRACT

Audio classification using breath and cough samples has recently emerged as a low-cost, non-invasive, and accessible COVID-19 screening method. However, a comprehensive survey shows that no application has been approved for official use at the time of writing, due to the stringent reliability and accuracy requirements of the critical healthcare setting. To support the development of Machine Learning classification models, we performed an extensive comparative investigation and ranking of 15 audio features, including less well-known ones. The results were verified on two independent COVID-19 sound datasets. By using the identified top-performing features, we have increased COVID-19 classification accuracy by up to 17% on the Cambridge dataset and up to 10% on the Coswara dataset compared to the original baseline accuracies without our feature ranking. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Background and Aims: Passive antibody administration through convalescent plasma has shown benefit in treating COVID-19 in the early stages of the disease in patients >65 years old, and in other viral outbreaks. A practical, rapid method to sterilize convalescent plasma while also maintaining antibody function would be valuable for safe treatment in future viral pandemics. Plasma sterilization by irradiation requires kGy of dose to deactivate bacteria and viruses of concern. Conventional lab-based irradiators would require days to reach such doses, while ultra-high dose rate irradiation (FLASH) would require minutes. We present a proof-of-concept on sterilizing plasma with 25 kGy in approximately 3 minutes without damaging the antibodies in the plasma. Methods: A Varian Trilogy LINAC was configured for 16 MeV FLASH electron irradiation. Frozen aliquots of convalescent plasma from patients with COVID-19 were placed in a 3D printed holder submerged in liquid aiming to preserve sample temperature (RT, 4°C or –20°C). The number of pulses was estimated with EBT-XD film. Samples were irradiated with a dose of 25 kGy in ~33,330 pulses over 185 seconds. Antibody binding against the receptor-binding domain (RBD) of the S1 region of SARS-CoV-2 was measured by ELISA pre- and post-irradiation. Results: Frozen plasma aliquots from 10 COVID-19 convalescent plasma donors were irradiated in frozen state to 25 kGy dose. IgG antibody binding against SARS-CoV-2 RBD after irradiation remained at 90.8% of non-irradiated samples (Fig. 1;OD 1.25 vs. 1.36, p<0.0003). (Figure Presented) Fig. 1 ( O034). Plasma aliquots from 10 convalescent plasma samples were irradiated at sterilizing 25-kGy doses. IgG binding to SARS-CoV-2 RBD antigen by ELISA is 90.8% compared to unirradiated. Conclusions: FLASH irradiation allows for rapid sterilization of blood plasma from potential pathogens while largely preserving antibody binding function and specificity.

ABSTRACT

Introduction: Telemedicine, once of limited scope, has become common and widespread due to the present and ongoing SARSCoV- 2 pandemic. Center to home delivery, the most common model, allows for convenient and efficient care. Concurrent with this groundshift, there is increasing attention to disparities in medical services, and how these disparities may impact patient outcomes. Telemedicine could be used to help bridge barriers to timely quality care, however, patient access and longstanding institutional biases may limit the potential. Healthcare providers must actively develop systems to ensure that telemedicine is optimized for people across the income spectrum. This exploratory analysis examined how economic disparities in patients being evaluated for obstructive sleep apnea may be associated with providers clinical impressions. The objective was to study the inter-method reliability of pre-test probability of obstructive sleep apnea assessed via telemedicine and in-person evaluations, and to compare that reliability between income classes. Methods: This is a secondary analysis of a pre-pandemic interrater reliability study, conducted between March 2017 and January 2019. Our researchers completed a randomized, blinded study comparing the pre-test probability of obstructive sleep apnea between an in-person physician and a separate physician seeing the same patient via televideo conferencing. Patients referred to the University of Rochester (UR) Sleep Center were eligible for the study. Women and men 30-70 years old were invited to participate. The patients were not necessarily referred to the center for evaluation of sleep disordered breathing. Patients with dementia, hearing or visual loss, severe psychiatric or developmental illness, or not fluent in English were excluded. Patients had adequate computer literacy, access to high speed internet, and a computing device with appropriate video camera and microphone.The primary objective of the original study was to assess the interrater reliability between the in-person and telemedicine raters for pre-test probability of sleep apnea (high, moderate, or low). Providers used clinical judgement from the history and examination to determine pre-test probabilityFor this present analysis, we assessed the inter-method reliability separately for strata defined by reported annual income level: low income (< $50,000), middle income ($50,000-$100,000), and high income (> $100,000). Reliability was quantified for each stratum using weighted kappa statistics given the ordinal nature of the outcome variable, pre-test probability of obstructive sleep apnea (high, moderate, or low). Weighted kappa statistics were compared between the income strata (high vs. middle, high vs. low, middle vs. low). The operant statistic assumed an approximate standard normal distribution under the null hypothesis of equal kappa values in the two income strata. The Bonferroni method was used to adjust the p-values for the three pairwise comparisons performed among the three income strata. Results: Data from 53 patients were avaiable for this analysis. 11 of these patients were in the low income group, 22 in the middle income, and 16 were in the high income group. 9 patients did not include their income bracket, and were not included in the analysis. Inter-method reliabilities, assessed using weighted kappa, were 0.83 (low income), 0.24 (middle income), and 0.66 (high income). When comparing between the strata, the kappa statistics were significantly different (p=0.005) between the low and moderate income groups. There was a trend between the high and moderate income groups that did not meet statistical significance (p=0.07). Conclusion: The intermethod reliability was substantial in the low income stratum, moderate in the high income stratum, and slight in the middle income group based on the kappa statistic. There was a significant difference in the reliability values of telemedicine versus in-person assessments between the low and middle income brackets, and there was a trend between the high and mo er te groups. Since the raters were unaware of the patients income levels, this association might suggest possible unconscious bias in evaluating for OSA. It may also suggest that beyond access to telemedicine technology, the quality of the care may also be influenced by socioeconomic factors. With telemedicine in its early stages, it is important to develop this technology that will minimize biases that could result from patients economic fortunes.

ABSTRACT

The pain, namely “Covid-19 epidemic", has caused many sacrifices, loss, and loneliness. Only those who have experienced traumatic losses can fully understand the pain that is hard to erase by the epidemic. This study focuses on designing a remote medical assistance vehicle used in quarantine areas in Vietnam to support epidemic prevention with simple, cheap, easy-to-use, and multi-function criteria. The proposed system includes a 3-layer vehicle for transporting supplies controlled remotely via Radio Frequency (RF) signals to help limit cross-infection for medical staff and volunteers. The main component is the RF transceiver circuit, which transmits and receives data wirelessly over 2.4 GHZ RF using IC Nrf24l01, Nordic standard SPI interface for remote control. DC motor driver circuit BTS7960 43A controls the motor to prevent overvoltage and current drop. Moreover, the vehicle integrates an electric sprayer to support disinfecting spray a Xiaomi camera to stream video and communicate directly with patients and healthy in isolation. Ultrasonic sensors and infrared sensors aim to scan obstacles through reflected waves. The reflected signals received from the barrier objects are used as input to the microcontroller. The microcontroller is then used to determine the distance of objects around the vehicle. If an obstacle is detected, the disinfectant sprayer can stop for several seconds to ensure the safety of medical staff if there is a pass. The system has a built-in light sensor that works at night. The system is deployed at a low cost and is evaluated through some experiments. It is expected to be easy to use and is an innovative solution for hospitals. Once the outbreak is over, the product can still be used in infectious disease areas. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

OBJECTIVES: COVID-19 vaccines are recommended for children ages ≥5 years. To develop effective interventions to increase uptake, this study explores reasons for parental hesitancy of child and adolescent COVID-19 vaccination. STUDY DESIGN: The Household Pulse Survey (HPS) is a nationally representative cross-sectional online household survey of adults aged ≥18 years that began data collection in April 2020 to help understand household experiences during the COVID-19 pandemic. METHODS: Using data from December 29, 2021, to January 10, 2022 (n = 11,478), we assessed child and adolescent COVID-19 vaccination coverage and parental intent to vaccinate their children and adolescents. Factors associated with child and adolescent vaccination coverage were examined using multivariable regression models. Reasons for not having had their child or adolescent vaccinated, stratified by parental vaccination status, were compared using tests of differences in proportions. RESULTS: Less than one-half (42.3%) of children and three-quarters (74.8%) of adolescents are vaccinated. Vaccination coverage was lower among households with lower education, as well as among children who had not had a preventive check-up in the past year. Parents of unvaccinated children were more likely to report that they do not trust COVID-19 vaccines, do not trust the government, and do not believe children need a COVID-19 vaccine compared to parents of vaccinated children. CONCLUSION: Efforts to increase uptake of vaccines by children and adolescents should target those with lower education, reassure parents of the vaccine safety and efficacy for themselves and their children/adolescents, and support yearly preventive care visits for their children.

ABSTRACT

The current COVID-19 pandemic has prevented individuals from gathering together physically because of mandated social distancing, enhancing the popularity of digital commensalism via video telecommunication. Since there has been only limited research on how social presence can influence food consumption experience, this study aimed to determine whether differing means of social presence could influence sensory and emotional responses to consumed meals. A total of 56 participants, comprised of 28 co-habiting pairs, ate meal samples on 3 separate days under 3 different commensality conditions: (1) physically together (“physical commensality”), (2) virtually together (“digital commensality”), and (3) alone (“eating alone”). The participants, under the three commensality conditions, rated attribute intensities and acceptance of meal samples and also self-reported emotional responses to the meals. The results demonstrated that participants liked physical commensality the most, followed by digital commensality, with the eating alone condition least liked. While the participants liked the meals under the physical commensality condition more than under the eating alone condition, there was no significant difference in overall meal liking between the physical and digital commensality conditions. Commensality conditions also induced variation in meal-evoked emotional profiles, with the physical and digital commensality conditions more associated with positive valence-related emotions. Differing commensality conditions resulted in variation in the duration of meal consumption, with the shortest eating duration occurring under the eating alone condition. In conclusion, this study emphasizes the great potential for improving eating environments by incorporating technological enhancement into commensality, especially when physical commensality is impossible.
