ABSTRACT
Understanding emotions that people express during large-scale crises helps inform policy makers and first responders about the emotional states of the population as well as provide emotional support to those who need such support. We present COVIDEMO, a dataset of similar to 3,000 English tweets labeled with emotions and temporally distributed across 18 months. Our analyses reveal the emotional toll caused by COVID-19, and changes of the social narrative and associated emotions over time. Motivated by the time-sensitive nature of crises and the cost of large-scale annotation efforts, we examine how well large pre-trained language models generalize across domains and timeline in the task of perceived emotion prediction in the context of COVID-19. Our analyses suggest that cross-domain information transfers occur, yet there are still significant gaps. We propose semi-supervised learning as a way to bridge this gap, obtaining significantly better performance using unlabeled data from the target domain. We make our code and data available at https://github.com/tsosea2/CovidEmo.
ABSTRACT
The world has witnessed the outbreak of the Covid-19 epidemic. Mainstream and social media are playing an important role in Covid-19 pandemic prevention. This research explores awareness, communication channels and effectiveness of communication in the Covid-19 pandemic in rural areas of Thua Thien Hue province, Central Vietnam. Primary information was collected from 181 respondents, who are farmers, non-farmers and students. Secondary information was collected from reports and statistical data. Television, word of mouth and local loudspeakers are the main channels of mainstream media while social media mentions the role of Facebook and Zalo to transfer Covid-19 pandemic information. Mainstream media is still the main channel of farmers and old people while non-farmers and young people tend to access information through social media. Communication has significantly contributed to improving awareness and action of rural people in the Covid-19 epidemic prevention. © 2022 World Association for Triple helix and Future strategy studies.

ABSTRACT
The negative impact of COVID on the respiratory system is well characterized in a general population. The increased complexity of COVID in lung transplant recipients (LTRs) and assessment of injury severity is less defined. We compared allograft injury as measured by donor derived cell-free DNA (dd-cfDNA) in LTRs with post-transplant COVID. We hypothesized more severe COVID infection would be associated with higher lung injury, as evidenced by higher dd-cfDNA. All LTRs positive for COVID with peri-infection dd-cfDNA (%, AlloSure, CareDx) from Memorial Hermann Hospital (MHH) and University of Texas Health Science Center San Antonio (UTHSC-SA) were evaluated. LTRs were stratified on hospitalized vs not hospitalized for COVID. Time between dd-cfDNA result and COVID infection was calculated and graphed. LTRs with concurrent immune events (acute cellular rejection or antibody mediated rejection) were excluded. Twenty-eight LTRs had post-COVID dd-cfDNA results available (MHH 18, UTHSC-SA 10). Peri-COVID infection dd-cfDNA trends are shown in Figure 1. Seventeen (61%) were hospitalized and 39% (n=11) were not. Median max dd-cfDNA in hospitalized LTRs was 1.10% (IQR 0.82, 2.40) drawn at median 50 days (IQR 35, 151) post-COVID. Median max dd-cfDNA in not hospitalized LTRs was 0.94% (IQR 0.45, 1.80) drawn at median 81 days (IQR 43, 235). As dd-cfDNA levels were not drawn at the same times post-COVID between hospitalized and not hospitalized patients, differences cannot be directly compared. However, there are clear elevations in median dd-cfDNA among COVID hospitalized LTRs indicating a higher degree of allograft injury in those patients. Both the dd-cfDNA elevation preceding date of COVID positivity and the following decay between hospitalized and not hospitalized LTRs could be important prognostically. Investigation into effect of COVID treatment on dd-cfDNA, time to return to dd-cfDNA baseline levels, and resolution of pulmonary function are warranted.

ABSTRACT
The process of digital transformation is recognized as a significant shift that requires time and frequently encounters resistance and avoidance from employees. The spread of COVID-19 compelled instructors and students to immediately transition all educational activities to take place online rather than undergoing the more gradual shift that was originally planned. To deal with the bad situation caused by the Covid-19, hybrid learning was employed. This paper explores students' perceptions towards hybrid learning implementation in a practical college in Vietnam. The research used a qualitative method. The samples were 250 students who were taking hybrid courses at the institution during the pandemic. Content analysis was used to process the qualitative data. The results reveal they were well-prepared with technology and stationery for the hybrid class. Flexibility, effectiveness, student engagement, convenience, and personalization are perceived benefits. Technical issues and distant student interaction must be addressed. Also, for onsite students, the fear of being infected by Corona virus and the distraction caused by the online group should also be considered. © 2022 Association for Computing Machinery.
ABSTRACT
Purpose: Infection is the leading cause of death within 1 year post lung transplant. Graft injury secondary to infection is affected by both source and organism. Donor derived cell-free DNA (dd-cfDNA) is a consistent marker of graft injury, but previously reported dd-cfDNA levels with infections have been inconsistent. We compared dd-cfDNA concentrations across different infection types. Method(s): We reviewed infections in lung transplant recipients (LTR) between 5/2019-6/2021 with paired dd-cfDNA at time of infection. All were confirmed infections (i.e. requiring therapy). Infection source (respiratory vs non-respiratory) and organism were collected. Samples were excluded if there was concurrent ACR, AMR or CLAD at time of dd-cfDNA. The primary endpoint was dd-cfDNA levels across cohorts. Result(s): Fifty paired samples from 20 LTR were identified;31 samples were excluded due to concurrent diagnoses. Infections included viral (n=18, 36%), bacterial (n=18, 36%), and fungal (n=10, 20%). Four cultures (8%) had multiple organisms. Most common within each group were CMV (n=4) and COVID (n=4) for viral, Pseudomonas aeruginosa (n=4) for bacterial, and Aspergillus (n=7) for fungal. Median dd-cfDNA was 1.30% in viral infections, 1.93% in bacterial, and 0.99% in fungal;respiratory infections (n=42) was 1.42% and 0.95% in non-respiratory (n=8). Conclusion(s): There was a statistically significant increase in dd-cfDNA between each infection compared to a normal cohort, but no statistical differences between infection groups. The trend towards significance of respiratory vs non-respiratory indicates that dd-cfDNA may be a useful marker of injury specific to the graft caused by infection. Further investigation with serial samples prior to and following treatment of the infection will be important to better understand this trend. (Figure Presented).
ABSTRACT
SESSION TITLE: Late Breaking Pulmonary and Education Topics Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/18/2022 01:30 pm - 02:30 pm PURPOSE: Healthcare professionals working in intensive care units (ICU) report high burnout levels, especially during the COVID-19 pandemic. Residents are particularly at risk for burnout and sleep deprivation, associated with increased medical errors. However, the relationship between sleep, burnout, and psychomotor vigilance has not been extensively studied in residents working in the medical ICU. METHODS: Fifty residents rotating in the ICU at an academic, tertiary care center were recruited for a prospective controlled trial during a consecutive four-week period from August 2021 – May 2022. Study parameters for two weeks in non-ICU rotations were compared with two week during ICU rotation. Residents wore a wearable sleep tracker for two weeks before and during their ICU rotation. ICU rotation dates were randomized based on a fixed annual schedule. Residents ranged in post-graduate training years one through four. Specialties included internal medicine, transitional year, emergency medicine, anesthesia, and medicine/pediatrics combined residency. Data collected included the Oldenburg burnout inventory score, Epworth Sleepiness Scale (ESS), a computer-based psychomotor vigilance test, American Academy of Sleep Medicine sleep diary, and wearable sleep tracker data. Statistical analysis was performed in Excel and R statistical software. RESULTS: Total sleep minutes detected by the wearable sleep-tracker decreased from 402 minutes (95% CI: 377-427) before ICU to 389 minutes (95%CI: 360-418) during ICU (p<0.05). Residents overestimated the amount of sleep they obtained via their validated daily log at 464 (95% CI: 452-476) minutes before ICU and 442 (95% CI: 430-454) minutes during ICU, which reflected a decrease in sleep of 22 minutes (p<0.02). ESS increased significantly from 5.93 (95% CI: 4.89, 7.07) before to 8.33 (95% CI: 7.09,9.58) during ICU (p<0.01). Oldenburg burnout inventory scores significantly increased during ICU by 8.30 (p<0.001). The total score before ICU was 34.50 (95% CI: 32.87-36.15) and after was 42.82 (95% CI: 40.65-44.98). Exhaustion and disengagement sub-scores significantly increased during ICU (3.94, 4.64, respectively;p<0.001). Interestingly, psychomotor vigilance testing scores showed no significant difference during ICU. CONCLUSIONS: ICU rotations are associated with significantly reduced sleep as objectively measured by sleep wearable and decreased self-reported sleep minutes. Residents overestimate the amount of sleep they obtain. Significant worsening of ESS was noted along with increased burnout in residents working in the ICU. Interestingly, the psychomotor testing remains unchanged. Further research is needed in this area to better understand this phenomenon. CLINICAL IMPLICATIONS: Residents may benefit from increased mandatory wellness events or days off to combat burnout and fatigue while in the ICU.

ABSTRACT
BACKGROUND: Due to the corona pandemic and also to the new competence-oriented catalogue of learning objectives in medicine and the master plan for medical studies 2020, the development of digital and practical teaching concepts has experienced a great increase in importance. AIM OF THE WORK: As a result of this development, it was an important task to establish this combination and incorporate it into the curricular teaching process. MATERIAL AND METHODS: The "Toolkit dermatology" was established, which was sent to a total of more than 650 students at German university dermatology clinics. Using educational films, the students were able to practice their skills. In a further development, the toolkit was combined with classroom lectures and the students were asked to evaluate the toolkit online. RESULTS: The vast majority of students (95-100%) clearly stated that the toolkit helped them to develop their practical skills. Some of them were in fact motivated to complete a clinical traineeship/practical tertial year in dermatology (21-88%). The combination of toolkit and subsequent classroom teaching was also rated very positively (82.2%), as this hybrid mode of teaching provided a better understanding. DISCUSSION: Digital teaching formats as part of the concept of blended learning, i.e. the combination of virtual and analogue teaching formats, are becoming increasingly more important. Solutions for the disadvantages, such as the lack of real interaction and suitable examination formats, still remain to be found; however, the toolkit project demonstrates that hands-on and digital teaching can lead to high student motivation as well as a high educational standard.

Background: Implementation of non-pharmacologic programs for people with dementia is often challenging in skilled nursing facilities (SNFs). We previously implemented Preventing Loss of Independence through Exercise (PLIÉ)-an integrative, group movement program for SNF residents with dementia-at the San Francisco VA. This study aimed to identify barriers and facilitators to implementing PLIÉ in VA SNFs nationally. Methods: We conducted a formative evaluation using semi-structured interviews with key stakeholder groups (SNF staff, SNF directors, and VA health system leaders). Questions focused on PLIÉ's fit with current dementia programs and VA policies, characteristics of individual SNFs, and training and implementation strategies. We used rapid qualitative analyses to identify key barriers and facilitators to inform implementation activities. Results: We interviewed 23 people from geographically diverse VA SNFs and national program offices (SNF staff, n=14;SNF directors, n=3;Health system leaders, n=7). Barriers to implementing PLIÉ included: 1) Staff turnover and limited dementia experience;2) Space restrictions and limits on group size (e.g. quarantine periods);and 3) technical issues with training staff remotely. Implementation facilitators for PLIÉ included: 1) compatibility with SNF needs and goals (e.g. maintaining function, reducing disruptive behavior);2) adaptability (e.g., engaging residents with limited mobility, using individual instruction during the COVID-19 pandemic);3) engaging and training interprofessional staff;and 4) alignment with national VA priorities and programs for dementia care. Conclusions: Successful implementation of evidence-based, non-pharmacologic programs such as PLIÉ is facilitated by compatibility, adaptability, interprofessionalism and alignment with VA priorities while barriers are related to staff, space, and technology. PLIÉ's adaptability suggests it is a scalable model for increasing access to non-pharmacologic dementia programs that can serve large numbers of SNF residents. These findings will inform the development of a remote training program for SNF staff to become instructors and facilitate national spread to other VA SNFs.
