<li><strong>How skeptics could be convinced (not persuaded) to get vaccinated against COVID-19</strong> -

Central to the SARS-CoV-2 pandemic strategy, COVID-19 vaccination depends on the population’s uptake decisions. Because at least 60% of the population needs to be vaccinated, but fewer, for example, in Germany are expected to do so, it is important to know how to convince those who are undecided or skeptical. According to the health care standard of enabling citizens to make informed decisions based on balanced information (boosting) – instead of persuasion or seduction (nudging) – a comparison of benefits and harms of having or not having the vaccination would be required to inform these groups. With the help of a representative survey, we investigated the contribution of fact boxes, an established intervention format for informed intentions. Study 1 shows the development of knowledge and evaluation of COVID-19 vaccinations by German citizens between Nov 2020 and Feb 2021. Study 2 reveals objective information needs and subjective information requirements of those laypeople at the end of Nov. Study 3 shows that the fact box format is effective for risk communication about COVID-19. Based on these insights, a fact box on the efficacy and safety of mRNA-vaccines was implemented with the help of a national health authority. Study 4 shows that fact boxes increase vaccination knowledge and positive evaluations of the benefit-harm ratio of vaccination in skeptics and undecideds. Our results demonstrate that simple fact boxes can be an effective boost of informed decision making among undecided and skeptical people, and that informed decisions can lead to more positive vaccination evaluations of the public.

SARS-CoV-2 rapid antigen point-of-care (PoC) and home tests are available to laypeople. This raises questions regarding the drivers and barriers of people’s willingness to use tests, their understanding of test results and the psychological and behavioural consequences of positive and negative test results. Four cross-sectional data collections, including survey items, open text answers and three experiments, were therefore conducted between December 2020 and March 2021, involving 4,026 German participants. The majority was willing to use PoC or home tests. People will be more likely to use tests when they are inexpensive and easy to use or when they are a necessary (given low infection rates) for obtaining access to public and social life. However, people urgently need information about what a test result means and how they should behave. Recommendations based on the present findings could make rapid testing a successful pillar of pandemic management.

Research on the relationship between investment growth and economic growth aims to determine the effect of Foreign Direct Investment in Indonesia on economic growth in 2009-2020. This research method uses quantitative methods with secondary data collected from various digital sources. The growth of foreign investment in Indonesia in 2009-2020 tends to be volatile and unstable. On the other hand, economic growth experienced stable growth throughout 2009-2020, although there was a decline in 2020 due to the Covid-19 pandemic. Based on the results of this study, it shows that the growth of Foreign Direct Investment in 2009-2020 does not significantly affect economic growth in Indonesia.

Throughout the COVID-19 pandemic, policy makers have tried to balance the effectiveness of lockdowns (or stay-at-home orders) with their potential mental health costs. Yet, two years into the pandemic, we are still lacking solid evidence about the emotional toll of lockdowns. Across two intensive longitudinal datasets with 14,511 observations collected in Australia in 2021 (total N = 441), we compare the degree, persistence, and regulation of people’s emotions on days in and out of lockdown. We find that lockdowns take an emotional toll, but that this toll is relatively mild. In lockdown, people experienced slightly more negative and slightly less positive emotion; returned to a mildly negative emotional state more quickly; and used low-effort emotion regulation strategies. We conclude that people are resilient to the challenges lockdowns pose to personal and social well-being.

<li><strong>Efficient direct and limited environmental transmission of SARS-CoV-2 lineage B.1.22 in domestic cats</strong> -
|

|

<div>
|

|
|
Susceptibility of domestic cats for infection with SARS-CoV-2 has been demonstrated by several experimental studies and field observations. We performed an extensive study to further characterize transmission of SARS-CoV-2 between cats, both by direct contact as well as by indirect contact. To that end, we estimated the transmission rate parameter and the decay parameter for infectivity in the environment. Using four groups of pair-transmission experiment, all donor (inoculated) cats became infected, shed virus and seroconverted, while three out of four direct contact cats got infected, shed virus and two of those seroconverted. One out of eight cats exposed to a SARS-CoV-2-contaminated environment became infected but did not seroconvert. Statistical analysis of the transmission data gives a reproduction number R0 of 2.18 (95% CI: (0.92-4.08), a transmission rate parameter {beta} of 0.23 day-1 (95% CI: 0.06-0.54), and a virus decay rate parameter of 2.73 day-1 (95% CI: 0.77-15.82). These data indicate that transmission between cats can be sustained (R0>1), however, infectiousness of a contaminated environment decays rapidly (mean duration of infectiousness 1/2.73 days). Infections of cats via exposure to a SARS-CoV-2-contaminated environment cannot be excluded if cats are exposed shortly after contamination.

<li><strong>Compensatory epistasis maintains ACE2 affinity in SARS-CoV-2 Omicron BA.1</strong> -
|
|||
|
|
<div>
|
|||
|
|
The Omicron BA.1 variant emerged in late 2021 and quickly spread across the world. Compared to the ancestral Wuhan Hu-1 strain and other pre-Omicron SARS-CoV-2 variants, BA.1 has many mutations, a number of which are known to enable antibody escape. Many of these antibody-escape mutations individually decrease the spike receptor-binding domain (RBD) affinity for ACE2 in the background of early SARS-CoV-2 variants, but BA.1 still binds ACE2 with high affinity. The fitness and evolution of the BA.1 lineage is therefore driven by the combined effects of numerous mutations. Here, we systematically map the epistatic interactions between the 15 mutations in the RBD of BA.1 relative to the Wuhan Hu-1 strain. Specifically, we measure the ACE2 affinity of all possible combinations of these 15 mutations (215 = 32,768 genotypes), spanning all possible evolutionary intermediates from the ancestral Wuhan Hu-1 strain to BA.1. We find that immune escape mutations in BA.1 individually reduce ACE2 affinity but are compensated by epistatic interactions with other affinity-enhancing mutations, including Q498R and N501Y. Thus, the ability of BA.1 to evade immunity while maintaining ACE2 affinity is contingent on acquiring multiple interacting mutations. Our results implicate compensatory epistasis as a key factor driving substantial evolutionary change for SARS-CoV-2 and are consistent with Omicron BA.1 arising from a chronic infection.

The biology driving individual patient responses to SARS-CoV-2 infection remains ill understood. Here, we developed a patient-centric framework leveraging detailed longitudinal phenotyping data, covering a year post disease onset, from 215 SARS-CoV-2 infected subjects with differing disease severities. Our analyses revealed distinct “systemic recovery” profiles with specific progression and resolution of the inflammatory, immune, metabolic and clinical responses, over weeks to several months after infection. In particular, we found a strong intra-patient temporal covariation of innate immune cell numbers, kynurenine- and host lipid-metabolites, which suggested candidate immunometabolic pathways putatively influencing restoration of homeostasis, the risk of death and of long COVID. Based on these data, we identified a composite signature predictive of systemic recovery on the patient level, using a joint model on cellular and molecular parameters measured soon after disease onset. New predictions can be generated using the online tool http://shiny.mrc-bsu.cam.ac.uk/apps/covid-systemic-recovery-prediction-app, designed to test our findings prospectively.

Abstract Introduction Contemporary literature has revealed that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causes acute sialadenitis and related symptoms, such as discomfort, pain, swelling, and secretory dysfunction in salivary glands. The secretory dysfunction is due to SARS-CoV-2 infection-induced xerostomia and other associated clinical courses such as sore tongue, mucosal ulcer, and gingivitis in the oral cavity. Furthermore, it has been reported that COVID-19 causes the development of other oral manifestations. Materials and Methods A prospective clinical follow-up (a prevalent cohort) study was conducted to identify the possible oral manifestations of SARS-CoV-2 infection among patients admitted at the Eka General Hospital COVID-19 treatment center. Furthermore, the study aimed to calculate the prevalence rate of oral clinical courses in the cohorts. The study had two follow-up phases: Hospital and patient-home-based. Results A total of 55 patients (36 males and 19 females) met the inclusion criteria and were followed for 7.5 weeks. The 3.5 weeks’ hospital-based prospective follow-up study documented an 18% (n=10) prevalence rate of oral clinical courses among the cohorts. Twelve oral symptoms appeared in these ten patients. The manifested oral symptoms were oral mucosal lesions (n=6), xerostomia (n=5), and thickening of saliva (n=1). The oral mucosal lesions per se consisted of aphthous lesions (n=3), candidiasis (n=1), geographic tongue (n=1), and localized gingivitis (n=1). On the other hand, the four weeks’ home-based follow-up study disclosed four newly manifested oral symptoms: hemorrhagic crust, bulla, buccal mucositis, and petechiae. These manifestations appeared among six patients (four males and two females) who had not manifested any oral symptoms during the hospital-based follow-up. Accordingly, the overall prevalence of oral clinical courses among patients presented with SARS-CoV-2 is raised from 18% (n=10) to 29% (n=16). Similarly, the number of clinical courses increased from 12 to 16 after four additional weeks of follow-up. Discussion The study9s findings suggest the importance of initiating oral health care for patients with COVID-19. Therefore, multidisciplinary healthcare approaches should be delivered to assure optimal health outcomes. Accordingly, oral health professionals must be a substantial part of the interdisciplinary approach in caring for patients with COVID-19.

Background Determining whether SARS-CoV-2 is or will be seasonal like other respiratory viruses is critical for public health planning, including informing vaccine policy regarding the optimal timing for deploying booster doses. To help answer this urgent public health question, we evaluated whether COVID-19 case rates in the United States and Europe followed a seasonal pattern using time series models. Methods We analyzed COVID-19 data from Our World in Data from Mar 2020 through Apr 2022 for the United States (and Census Region) and five European countries (Italy, France, Germany, Spain, and the United Kingdom). For each, anomalies were identified using Twitter9s decomposition method and Generalized Extreme Studentized Deviate tests. We performed sensitivity analyses to determine the impact of data source (i.e., using US Centers for Disease Control and Prevention [CDC] data instead of OWID) and whether findings were similar after adjusting for multiple covariates. Finally, we determined whether our time series models accurately predicted seasonal influenza trends using US CDC FluView data. Results Anomaly plots detected COVID-19 rates that were higher than expected between November and March each year in the United States and Europe. In the US Southern Census Region, in addition to seasonal peaks in the fall/winter, a second peak in Aug/Sep 2021 was identified as anomalous. Results were robust to sensitivity analyses. Conclusions Our results support employing annual protective measures against SARS-CoV-2 such as administration of seasonal booster vaccines or other non-pharmaceutical interventions in a similar timeframe as those already in place for influenza prevention.

Turnover intention is the tendency or intention of employees to stop working from their jobs voluntarily or move from one workplace to another according to their own choice. The purpose of this study is to investigate the effect of burnout on turnover intentions, the organizational commitment to turnover intentions, and the indirect relationship between burnout and turnover intentions through organizational commitment. This type of research is a quantitative study. The sampling in this study used probabilistic sampling using cluster sampling and simple random sampling. The study population consisted of healthcare professionals from five hospitals in Surabaya as referrals for Covid19 patients. The sample contains 100 respondents. Route analysis by the Smart PLS 2.0 program is used as a data analysis method. The results show that burnout affects turnover intentions. Burnout adversely affects an organization’s commitment, which in turn adversely affects the intent of leaving a job. In addition, the results of indirect impact tests show that organizational commitment can mediate the relationship between burnout and willingness to leave.

COVID-19 pandemic dramatically changed the face of the world, including Indonesia. With more economic relief packages injected into public spending, corruption opportunities have risen, especially under the weakening corruption monitoring system. This article presents significant findings from the survey on the practice of corruption during the pandemic that can paint an understanding of corruption in Indonesia. Two survey rounds were conducted with respondents around Indonesia starting mid-to-end 2020, gathering 2,093 responses. The ordinary least-square (OLS) regression unveils that people who live in rural areas or spend less than the common people tend to commit or be involved in the practice of corruption. People who live in the rural areas or receive less income tend to perform corruption to close the income gap. It is also found that people with higher education levels tend to perform corruption. Higher corruption rents and broad opportunities for power abuse promote corruption in a well-educated society.

<li><strong>Deciphering inhibitory mechanism of coronavirus replication through host miRNAs-RNA-dependent RNA polymerase (RdRp) interactome</strong> -
|

<div>

Despite what we know so far, Covid-19, caused by SARS-CoV-2 virus, remains a pandemic that still require urgent healthcare intervention. The frequent mutations of the SARS-CoV-2 virus has rendered disease control with vaccines and antiviral drugs quite difficult and challenging, with newer variants surfacing constantly. There is therefore the need for newer, effective and efficacious drugs against coronaviruses. Considering the role of RNA dependent, RNA polymerase (RdRp) as an important enzyme necessary for the virus life cycle and its conservation among coronaviruses, we investigated potential host miRNAs that can be employed as broad-range antiviral drugs averse to coronaviruses, with particular emphasis on BCoV, MERS-CoV, SARS-CoV and SARS-CoV-2. miRNAs are small molecules capable of binding mRNA and regulate expression at transcriptional or translational levels. Our hypothesis is that host miRNAs have the potential of blocking coronavirus replication through miRNA-RdRp mRNA interaction. To investigate this, we downloaded the open reading frame (ORF 1ab) nucleotide sequences and used them to interrogate miRNA databases for miRNAs that can bind them. We employed various bioinformatics tools to predict and identify the most effective host miRNAs. In all, we found 27 miRNAs that target RdRp mRNA of multiple coronaviruses, of which three - hsa-miR-1283, hsa-miR-579-3p, and hsa-miR-664b-3p target BCoV, SARS-CoV and SARS-CoV-2. Additionally, hsa-miR-374a-5p has three bovine miRNAs homologs viz bta-miR-374a, bta-miR-374b, and bta-miR-374c. Inhibiting the expression of RdRp enzyme via non-coding RNA is novel and of great therapeutic importance in the control of coronavirus replication, and could serve as a broad-spectrum antiviral, with hsa-miR-1283, hsa-miR-579-3p, and hsa-miR-664b-3p highly promising.
