ABSTRACT

SARS-CoV-2 has infected more than 600 million people worldwide over the last 2.5 years. So far, there efficacy of many antiviral drugs against COVID-19 has been evaluated only in small studies conducted in different countries. Objective. To assess the efficacy of umifenovir in patients with COVID-19. Materials and methods. We performed systematic search of publications in the PubMed and Google Scholar databases. Sixteen studies with a total of 1,843 patients were included in the analysis. The following endpoints were evaluated: frequencies of negative PCR test on days 7 and 14;mortality in patients with mild, moderate, and severe disease;and frequency of fever resolution on day 7. Results. We found that patients receiving umifenovir demonstrated a significantly higher frequency of negative PCR test on day 7 than patients who received no causal therapy or other antiviral drugs (odds ratio (OR) 1.69, 95% confidence interval (CI): 1.09-2.62, p = 0.02, I2 = 13%). This difference was even more significant among patients with mild to moderate COVID-19 (OR: 2.03, 95% CI: 1.24-3.32, p = 0.005, I2 = 0%), as well as on day 14 (OR: 2.02, 95% CI: 1.35-3.94, p = 0.0007, I2 = 50%). We also observed a reduced risk of death in the studies that included only patients with mild and moderate disease (JR: 0.53, 95% CI: 0.33-0.83, p = 0.006, I2 = 0). Umifenovir therapy did not affect the frequency of fever resolution by day 7 (OR: 0.87, 95% CI: 0.49-1.56, p = 0.64, I2 = 0%). Conclusion. Umifenovir significantly accelerated virus elimination by days 7 and 14 among patients with mild to moderate COVID-19. Umifenovir also reduced the risk of death compared to other antiviral drugs.Copyright © 2022, Dynasty Publishing House. All rights reserved.

ABSTRACT

Objective To explore the efforts of applying mindfulness stress reduction therapy in alleviating stress reactions and burnout among head nurses in the context of the Coronavirus disease 2019 (COVID-19). Methods This was a quasi experimental study. In June 2021, 109 head nurses with mild or above burnout measured by Maslach Burnout Inventory (MBI) from 12 hospitals in Zhangjiagang City were selected as the research objects to implement mindfulness-based stress reduction therapy for 8 weeks, and the scores of the Five Facet Mindfulness Question-naire (FFMQ), Stress Response Questionnaire (SRQ) and MBI of the head nurses were compared before and after the intervention. Results The five dimensions of observation, description, perceived action, non-judgment, and non-response and the total scores of the FFMQ were (26.28 ± 1.32), (26.94 ± 1.29), (25.49 ± 0.99), (25.45 ± 1.05), (23.48 ± 1.01), and (127.63 ± 3.78) of the post-intervention, which were higher than the pre-intervention scores of (25.04 ± 1.37), (25.04 ± 1.37), (25.37 ± 1.18), (24.15 ± 1.00), (24.09 ± 0.98), (22.26 ± 1.04), and (120.90 ± 4.06), with statistically significant differences (t values were -39.21- -15.36, all P<0.01). The three dimensions of emotional, somatic, and behavioral responses and total scores of the post-intervention SRQ were (27.70 ± 6.12), (20.75 ± 4.20), (15.19 ± 3.11), and (65.99 ± 12.43), respectively, lower than the pre-intervention scores of (29.19 ± 6.91), (21.86 ± 5.20), (16.48 ± 4.16), and (70.12 ± 15.97), with statistically significant differences (t values were 5.70-9.33, all P<0.01);the scores of dimensions of emotional exhaustion and depersonalization in post-intervention MBI were (26.24 ± 4.60) and (5.96 ± 1.25), lower than the pre-intervention scores of (29.66 ± 6.02) and (6.90 ± 1.59). The post-intervention scores of personal fulfillment (32.37 ± 5.02), higher than the pre-intervention scores of (28.60 ± 6.04), all with statistically significant differences (t=15.36, 13.50, - 9.65, all P<0.01). Conclusions The implementation of mindfulness stress reduction therapy for the head nurses can relieve their work pressure due to the prevention and control of the COVID-19 epidemic, reshape their healthy psychology, and reduce job burnout. © The Author(s) 2023.

ABSTRACT

Wastewater surveillance has been widely used to track the prevalence of SARS-CoV-2 in communities. Although some studies have investigated the decay of SARS-CoV-2 RNA in wastewater, understanding about its fate during wastewater transport in real sewers is still limited. This study aims to assess the impact of sewer biofilms on the dynamics of SARS-CoV-2 RNA concentration in naturally contaminated real wastewater (raw influent wastewater without extra SARS-CoV-2 virus/gene seeding) using a simulated laboratory-scale sewer system. The results indicated that, with the sewer biofilms, a 90% concentration reduction of the SARS-CoV-2 RNA was observed within 2 h both in wastewater of gravity (GS, gravity-driven sewers) and rising main (RM, pressurized sewers) sewer reactors. In contrast, the 90% reduction time was 8–26 h in control reactors without biofilms. The concentration reduction of SARS-CoV-2 RNA in wastewater was significantly more in the presence of sewer biofilms. In addition, an accumulation of c.a. 260 and 110 genome copies/cm2 of the SARS-CoV-2 E gene was observed in the sewer biofilm samples from RM and GS reactors within 12 h, respectively. These results confirmed that the in-sewer concentration reduction of SARS-CoV-2 RNA in wastewater was likely caused by the partition to sewer biofilms. The need to investigate the in-sewer dynamic of SARS-CoV-2 RNA, such as the variation of RNA concentration in influent wastewater caused by biofilm attachment and detachment, was highlighted by the significantly enhanced reduction rate of SARS-CoV-2 RNA in wastewater of sewer biofilm reactors and the accumulation of SARS-CoV-2 RNA in sewer biofilms. Further research should be conducted to investigate the in-sewer transportation of SARS-CoV-2 and their RNA and evaluate the role of sewer biofilms in leading to underestimates of COVID-19 prevalence in communities.

ABSTRACT

PurposeThis paper aims to identify key factors for a contextualised Systemic Risk Governance (SRG) framework and subsequently explore how systemic risks can be managed and how local institutional mechanisms can be tweaked to deal with the complex Indonesian risk landscape.Design/methodology/approachUsing a case study from Palu triple-disasters in Central Sulawesi, Indonesia, the authors demonstrate how inland earthquakes in 2018 created cascading secondary hazards, namely tsunamis, liquefactions and landslides, caused unprecedented disasters for the communities and the nation. A qualitative analysis was conducted using the data collected through a long-term observation since 2002.FindingsThe authors argue that Indonesia has yet to incorporate an SRG approach in its responses to the Palu triple-disasters. Political will is required to adopt more appropriate risk governance modes that promote the systemic risk paradigm. Change needs to occur incrementally through hybrid governance arrangements ranging from formal/informal methods to self- and horizontal and vertical modes of governance deemed more realistic and feasible. The authors recommend that this be done by focusing on productive transition and local transformation.Originality/valueThere is growing awareness and recognition of the importance of systemic and cascading risks in disaster risk studies. However, there are still gaps between research, policy and practice. The current progress of disaster risk governance is not sufficient to achieve the Sendai Framework for Disaster Risk Reduction (2015–2030) unless there is an effective governing system in place at the local level that allow actors and institutions to simultaneously manage the interplays of multi-hazards, multi-temporal, multi-dimensions of vulnerabilities and residual risks. This paper contributes to these knowledge gaps.

ABSTRACT

There was a change in the environment and food security threat during the COVID-19 pandemic. Many countries, including Indonesia, are forced to allocate funds to reduce the risk of this disaster. The Government Republic of Indonesia, through the Ministry of Social Affairs, has launched a Social Cash Assistance Program for 10 million families affected by COVID-19. This study aims to identify how families affected by COVID-19 take advantage of this social cash assistance. The study was conducted on the beneficiaries of social assistance, in cash transfer of IDR 600,000 (USD 40), per month, for three months. This study involved 2290 beneficiaries as respondents spread across 12 provinces. The sampling technique was the Cohen Manion Morrison Table by proportional stratified random sampling. The findings show that (1) 99% of cash assistance is used for basic needs, especially for food, and (2) cash assistance could be used for basic needs for around two to three weeks, thereby strengthening food security. Recommendations are submitted based on the results of this study related to social cash assistance and food security. The first is that this assistance still needs to be continued until the COVID-19 pandemic is over. It is to help families affected by the COVID-19 pandemic meet their daily needs. Second, most respondents do not have a fixed income during the pandemic, so providing capital and business startups are needed to increase family income sustainably to maintain food security.

ABSTRACT

Low quality of the air is becoming a major concern in urban areas. High values of particulate matter (PM) concentrations and various pollutants may be very dangerous for human health and the global environment. The challenge to overcome the problem with the air quality includes efforts to improve healthy air not only by reducing emissions, but also by modifying the urban morphology to reduce the exposure of the population to air pollution. The aim of this contribution is to analyse the influence of the green zones on air quality mitigation through sensor measurements, and to identify the correlation with the meteorological factors. Actually, the objective focuses on identifying the most significant correlation between PM2.5 and PM10 concentrations and the wind speed, as well as a negative correlation between the PM concentrations and wind speed across different measurement locations. Additionally, the estimation of slight correlation between the PM concentrations and the real feel temperature is detected, while insignificant correlations are found between the PM concentrations and the actual temperature, pressure, and humidity. In this paper the effect of the pandemic restriction rules COVID-19 lockdowns and the period without restriction are investigated. The sensor data collected before the pandemic (summer months in 2018), during the global pandemic (summer months 2020), and after the period with restriction measures (2022) are analysed.

ABSTRACT

The COVID-19 pandemic has altered people's lifestyles around the world. Prevention of recurrent episodes of the disease and mitigation of its consequences are especially associated with effective post-COVID-19 rehabilitation in patients. The aim of the study was to evaluate the effects of the drug Likopid (glucosaminylmuramyl dipeptide, GMDP) for post-COVID-19 rehabilitation in patients. Material and methods. Patients who recovered from mild to moderate COVID-19 (n=60, mean age 54+/- 11.7 years) were randomized into the observation group (n=30, 15 men and 15 women) who received 2 courses of Licopid (1 mg twice a day) and the comparison group (n=30, 15 men and 15 women). Analysis of the phenotypic and functional characteristics of the innate immune cellular factors was carried out before the start of immunomodulatory therapy, immediately after the end of the course, and also after 6 months observations. In order to assess the quality of life of all patients, we used the SF-36 Health Status Survey and the Hospital Anxiety and Depression Scale questionnaires. Results. During assessing the effect of immunomodulatory therapy on the parameters of innate immunity of patients at the stage of rehabilitation after COVID-19, an increase in the protective cytolytic activity of CD16+ and CD8+Gr+ cells, as well as a persistent increase in TLR2, TLR4 and TLR9 expression was found, which indicates the antigen recognition recovery and presentation at the level of the monocytic link of the immune system. The use of GMDP as an immunomodulatory agent resulted in an 8-fold reduction in the frequency and severity of respiratory infections due to an increase in the total monocyte count. As a result of assessing patients' quality of life against the background of the therapy, a positive dynamic in role functioning was revealed in patients. In the general assessment of their health status, an increase in physical and mental well-being was noted during 6 months of observation. The comparison group showed no improvement in the psychoemotional state. Discussion. The study demonstrated the effectiveness of GMDP immunomodulatory therapy in correcting immunological parameters for post-COVID-19 rehabilitation in patients. The data obtained are consistent with the previously discovered ability of GMDP to restore impaired functions of phagocytic cells and induce the expression of their surface activation markers, which in turn contributes to an adequate response to pathogens. Conclusion. The study revealed that the correction of immunological parameters with the use of GMDP in COVID-19 convalescents contributed not only to a decrease in the frequency and severity of respiratory infections, but also to an improvement in the psycho-emotional state of patients, and a decrease in anxiety and depression.Copyright © Eco-Vector, 2023.

ABSTRACT

The patient presented with nausea, appetite loss, and fatigue. She had received two doses of Pfizer/BioN-Tech BNT162b2 mRNA vaccine (COMIRNATY) for coronavirus disease 2019 (COVID-19). Acute liver injury was noted 14 days after the first dose of the vaccine. Re-exposure through the second dose worsened the liver injury. After liver biopsy on the third day of admission, methylprednisolone (1000 mg) was administered. Liver histology showed acute hepatitis with diffuse lobular inflammation/necrosis and lymphocyte-dominant infiltra-tion in the portal areas. The patient was diagnosed with drug-induced liver injury due to the COVID-19 vaccine based on the Digestive Disease Week Japan 2004 (DDW-J) scale, which assesses the temporal relationship, liver biopsy, and laboratory findings. With improvements in the blood test parameters, prednisolone was gradually tapered and stopped. One month later, no biochemical signs of relapse were noted. To our knowledge, this is the first report describing liver injury after the administration of the Pfizer COVID-19 vaccine in Japan.Copyright © 2022 The Japan Society of Hepatology.

ABSTRACT

Objective: COVID-19 has emerged as a significant global health crisis causing devastating effects on world population accounting for over 6 million deaths worldwide. Although acute RTI is the prevalent cause of morbidity, kidney outcomes centered on a spectrum of AKI have evolved over the course of the pandemic. Especially the emerging variants have posed a daunting challenge to the scientific communities, prompting an urging requirement for global contributions in understanding the viral dynamics. In addition to canonical genes, several subgroup- specific accessory genes are located between the S and E genes of coronaviruses regarding which little is known. Previous studies have shown that accessory proteins (aps) in viruses function as viroporins that regulate viral infection, propagation and egress [1]. In this study we attempted to characterize the function of aps of coronavirus variants as ion channels. Furthermore, we also probed the interaction of ap4 with the host system. Method(s): Serial passaging (selection pressure), growth kinetics, confocal imaging, genome sequence analysis and proteomics were performed in Huh-7, MRC5 cells and/or human monocyte derived macrophages. Potassium uptake assay was performed in a Saccharo myces cerevisiae strain, which lacks the potassium transporters trk1 and trk2. Ion conductivity experiments were performed in Xenopus laevis oocytes using Two Electrode Voltage Clamp (TEVC) method. Result(s): Serial passaging demonstrated the acquisition of several frameshift mutations in ORF4 resulting in C-terminally truncated protein versions (ap4 and ap4a) and indicate a strong selection pressure against retaining a complete ORF4 in vitro. Growth kinetics in primary cells illustrated a reduction of viral titers when the full-length ap4 was expressed compared to the C-terminally truncated protein ap4a. Confocal imaging showed that ap4 and ap4a are not exclusively located in a single cellular compartment. Potassium uptake assay in yeast and TEVC analyses in Xenopus oocytes showed that ap4 and ap4a act as a weak K+ selective ion channel. In addition, accessory proteins of other virus variants also elicited microampere range of currents. Conclusion(s): Our study provides the first evidence that ap4 and other accessory proteins of coronavirus variants act as viroporins. Future studies are aimed at demonstrating the role of ap4 during the viral life cycle by modulating ion homeostasis of host cell in vivo (interacting proteins obtained from proteomic studies) and thereby serve as a tool for potential drug target.

ABSTRACT

Information technology and supply chain agility are in vogue. The present study aims to investigate the impact of information technology (IT) on supply chain agility and its outcomes such as cost reduction and operational performance in fast food companies' chains. A total of 240 employees from fast food chains were selected as respondents. Data was collected using five-point Likert scale questionnaire developed from previous studies. The statistical results confirmed that adoption of IT is playing a vibrant role in achieving supply chain agility and supply chain agility helps to reduce cost and improves operational performance of firms. The study model provides a useful framework to examine the impact of IT adoption on supply chain agility and its outcomes. In conclusion, the firms have to focus on their supply chain management and make it efficient and agile by implementing the advanced technologies to gain operational performance. Implications have been discussed.

ABSTRACT

The most common causes of acute hepatitis in children are hepatitis A and autoimmune hepatitis. Hepatitis in the course of Wilson's disease is sporadically registered in adolescents. An increase of activity of aminotransferases both in the course of multisystem inflammatory syndrome in children (MIS-C) and in the course of COVID-19 has been observed. Hepatitis is common in children with MIS-C and is associated with a more severe presentation and persistent elevation of liver function tests. To date, no cases of acute hepatitis in children due to COVID-19 have been reported. We present 2 cases of acute hepatitis in children where the only cause seems to be a previous asymptomatic SARS-CoV-2 infection.Copyright © 2023 Termedia Publishing House Ltd.. All rights reserved.

ABSTRACT

The outbreak of COVID-19 has increased the demand for new drug development. That has led to a growing interest in chemoinformatics, which is valuable information technology to predict chemical reactions. The use of enzymes as catalysts is gaining importance in terms of the environment and reaction efficiency. In order to predict the best enzyme to obtain the desired product, the target chemical equation is compared with typical chemical equations of enzymes classified by Enzyme Commission number (EC number) using clustering. The EC number of the chemical equation that is evaluated to have the highest similarity is predicted. © 2023, ICIC International. All rights reserved.

ABSTRACT

Background and purpose: The COVID-19 pandemic have led to some psychological disorders and sleep problems that should be taken into account after recovery. After recovering from COVID-19 people are at risk of sleep disorders, depression, and low quality of life and there is paucity of information about this issue. The present study aimed to compare the effectiveness of mindfulness and aerobic exercise on depressive symptoms, perceived stress, and sleep quality in recovered COVID-19 patients. Material(s) and Method(s): An intervention field research was performed in 60 male and female patients (mean age: 39.52+/-5.82) recovered from COVID-19 in Kermanshah, Iran. Participants were randomly divided into four groups (n=15): 1) attending mindfulness-based stress reduction (MBSR) program, 2) aerobic exercise, 3) combination of MBSR and aerobic exercise, and 4) control group. The study was carried out at four stages: pretest, interventions, post-test, and follow-up test. Dependent variables included depressive symptoms, perceived stress, and sleep quality. Bonferroni Post hoc test in 4*3 mixed ANOVA was used for data analysis. Result(s): In this study, depression and perceived stress reduced in all experimental groups compared to the control group (P= 0.001). Also, sleep quality improved in these groups compared to the control group (P= 0.001). Post hoc tests showed the superiority of combination of MBSR and aerobic exercise compared to other interventions. Conclusion(s): According to current study, combination of MBSR and physical activity shows to be more helpful than mindfulness training and physical activity alone in improving psychological problems and sleep quality after recovering from COVID-19.Copyright © 2023, Mazandaran University of Medical Sciences.

ABSTRACT

This rapid review provides an overview of recent literature on the nature of digital interventions for young people in terms of technologies used, substances and populations targeted, and theoretical or therapeutic models employed. A keyword search was conducted using MEDLINE and other databases for 2015-2021. Following a title/ and full-text screening of articles and consensus decision on study inclusion, data extraction proceeded using an extraction grid. Data synthesis relied on an adapted conceptual framework (Stockings et al., 2016) that involved a three-level treatment spectrum for youth substance use (prevention, early intervention, and treatment). The review identified 43 articles describing 39 digital interventions. Most were early interventions (n = 28), followed by prevention (n = 6) and treatment (n = 5). Of the five technologies identified, web-based interventions (n = 14) were most common. Digital interventions have mainly focused on alcohol use (n = 20), reflecting limited concern for other substance use and co-occurring use. Yet the rise in substance use and related harms during the Covid-19 pandemic highlights a critical need for more innovative substance use interventions. Technologies with more immersive and interactive features, such as VR and game-based interventions, call for further exploration. Only one intervention was culturally tailored and purposefully designed for gender minority youth, and another was geared to young men. As well, most interventions used a personalized or normative feedback approach, while a harm reduction approach guided only one intervention. The incorporation of culturally tailored interventions and harm reduction approaches may promote uptake and stronger engagement with digital interventions amongst youth.

ABSTRACT

The purpose of this study was to examine nurses' experience of quality care for hospitalized patients with a history of opioid use disorder or self-injection of opioids and whether hospital, unit, or nurse characteristics impacted experiences of quality care. A secondary aim of the study was to understand how nurses' experiences of quality care for this population have been impacted by the COVID-19 pandemic. The Institute of Medicine's Six Domains of Health Care Quality were used to define quality care in this study. A national sample of 179 nurses completed an online survey regarding their experiences caring for patients with opioid use disorders. The majority of the participants were staff nurses who worked in emergency departments, critical care units, or mother baby units. Only 41.9% of the participants had received education regarding substance use disorders from their employers, and even less had participated in harm reduction education. Only 45% of the nurses had knowledge regarding harm reduction strategies for this population. The participants experienced a low number of restrictive safety measures and an average number of adverse events and effective care interventions when caring for patients with opioid use disorders. The nurses rated quality care and satisfaction as average. Correlation and linear regression analysis suggested trends in nurse, hospital and unit characteristics that are associated with nurses' experiences caring for this population;substance use disorder education, harm reduction education, and unit type were most often associated with nurses' experiences. Content analysis of open-ended questions regarding equity, patient-centeredness, timeliness and the impact of COVID-19 on experiences of quality care supported quantitative findings in the study and provided insight into the nurses' experiences. The findings in this study contribute to current evidence regarding the need for standardized hospital policies and practices aimed at improving quality care for patients with opioid use disorders. These policies and practices should incorporate harm reduction strategies that are patient-centered and evidence-based. Hospitals and nursing schools should provide education aimed at reducing stigma and improving care for this population. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

ABSTRACT

Organ transplant recipients receive immunosuppressive drugs and hence are at high risk for COVID-19 due to their compromised immunity. This study assessed 1,370 liver transplant recipients who were followed at our hospital. A total of 12 patients got COVID-19: 5 recipients <50-years-old had mild disease, 7 recipients >60-years-old had moderate to severe disease, and 2 patients died. In addition, not all patients received 2 vaccinations, suggesting that the immunization is important for COVID-19 prophylaxis even in this patient population. One recipient was successfully treated with a combination of a reduced dose of immunosuppressive drugs, dexamethasone, remdesivir, and antibiotics, which is being established as an effective therapy for COVID-19.Copyright © 2022 The Japan Society of Hepatology.

ABSTRACT

A novel phenoxy-bridged trinuclear nickel(ii) complex [Ni3(mu-L)2(bipy)3](1) (where H3L= (E)-2-hydroxy-N-(2-hydroxy-3,5-diiodophenyl)-3,5-diiodobenzohydrazonic acid, bipy = 2,2'-bipyridyl) has been designed and synthesized as a potential antivirus drug candidate. The trinuclear Ni(ii) complex [Ni3(mu-L)2(bipy)3](1) was fully characterized via single crystal X-ray crystallography. The unique structure of the trinuclear nickel(ii) complex crystallized in a trigonal crystal system with P3221 space group and revealed distorted octahedral coordination geometry around each Ni(ii) ion. The X-ray diffraction analysis established the existence of a new kind of trinuclear metal system containing nickel(ii)-nickel(ii) interactions with an overall octahedral-like geometry about the nickel(ii) atoms. The non-bonded Ni-Ni distance seems to be 3.067 and 4.455 A from the nearest nickel atoms. The detailed structural analysis and non-covalent supramolecular interactions are also investigated by single crystal structure analysis and computational approaches. Hirshfeld surfaces (HSs) and 2D fingerprint plots (FPs) have been explored in the crystal structure to investigate the intermolecular interactions. The preliminary analysis of redox and magnetic characterization was conducted using cyclic voltammetry measurements and a vibrating sample magnetometer (VSM), respectively. This unique structure shows good inhibition performance for SARS-CoV-2, Omicron and HIV viruses. For insight into the potential application of the Ni(ii) coordination complex as an effective antivirus drug, we have examined the molecular docking of the trinuclear Ni(ii) complex [Ni3(mu-L)2(bipy)3](1) with the receptor binding domain (RBD) from SARS-CoV-2 (PDB ID: 7MZF), Omicron BA.3 variant spike (PDB ID: 7XIZ), and HIV protease (PDB ID: 7WCQ) viruses. This structure shows good inhibition performance for SARS-CoV-2, Omicron S protein and HIV protease viruses;the binding energies (DELTAG) and the respective Ki/Kd (inhibition/dissociation constants) correlation values are -8.9 (2.373 muM or 2373 nM), -8.1 (1.218 muM or 1218 nM) and -7.9 (0.874 muM or 874 nM), respectively. The results could be used for rational drug design against SARS-CoV-2 Omicron variant and HIV protease viruses.Copyright © 2023 The Royal Society of Chemistry.

ABSTRACT

The study investigates the role of corporate sustainability disclosures in moderating the link between country-level uncertainties (economic policy uncertainty, political uncertainty and uncertainty due to climate change) and firms' risks (total risk, market risk, and default risk) in the worldwide tourism firms. We consider the volume of ESG (environmental, social and governance) activities disclosures by the firms as a proxy of corporate sustainability disclosures. The study also explores the link between sustainability disclosures and firms' risks to validate the risk-reduction hypothesis. The study further highlights the relevance of country-level uncertainties in increasing firms' risks. The findings indicate that corporate sustainability disclosures can assist in mitigating tourism firms' risks during periods of heightened country-level uncertainties. The study also documents the significance of sustainability disclosures in reducing the effect of uncertainties on tourism firms' risks during the COVID-19 period. The results validate the risk-reduction hypothesis indicating that firms' engagement in corporate sustainability practices facilitates risk mitigation efforts during periods of escalated external uncertainties. By demonstrating that firms that engage in sustainability practices and provide required disclosures are better equipped to manage risks during periods of increased uncertainty, the study provides valuable insights for industry stakeholders, including investors, policymakers, and firms themselves.

Lack of access to cancer prevention education, early screening, and timely treatment, particularly in low socioeconomic, underserved communities, are cited as substantial barriers to improving survivorship. Outreach educational efforts with on-site screenings offered in partnership with community groups are known to be valuable in encouraging community members' uptake of healthy behaviors and adherence to screening recommendation. To create more engaging events, a community-academic partnership, We Engage 4 Health (WE4H), co-created 11 unique 4-panel comic-style stories designed to be read aloud together as attendees visit each event table. These colorful stories are shared on boards that stand on each table and are offered in both English and Spanish at this time. Many tables also have an accompanying hands-on activity. Together, they lead to meaningful "low stakes" discussions which support understanding of seemingly complex health information. Story topics include the cause of cancer (Cells Gone Wrong), cancer risk factors (Reducing Your Risk), the role of primary care in cancer screening (Primary Care for Prevention), the purpose of research (short Research Ready) and details about specific cancer types (Combatting Colon Cancer, Blocking Breast Cancer, Looking for Lung Cancer, Silencing Skin Cancer, Hindering HPV, and Professional Prostate Protection) and COVID-19 (Take Your Best Shot FAQs). A health passport is used to facilitate table visitation and survey collection at each table enables meaningful evaluation of the event as well as provides the community hosts and their partners baseline cancer data to inform future programing. In 2022, WE4H and the University of Cincinnati Cancer Center partnered with three different communities to co-host pilot events that served over 100 adult residents. Community, research interns and university students volunteered to work the tables at the event and received training prior. Post event surveys and discussions indicated that community partners appreciated the different take on a health fair event. Most volunteers indicated that they would enjoy volunteering again. Attendees indicated that they liked the graphic-style story format used and most preferred it to text and text with graphics approaches. Taken together, the data indicates that Reducing Your Risk events are useful in meaningfully engaging hard to reach, at risk attendees. Additional in-person and virtual events are being planned for 2023 as an approach to reach the medically underserved throughout our region.
