Learning from others’ dishonesty usually involves various motivations, such as the desire to pursue self-interest and the tendency to conform to a dishonest group norm. However, these different processes have rarely been dissociated, which impedes our understanding of how an individual dishonest act propagates and becomes popular in a community. We built a comprehensive model based on the framework of reinforcement learning (RL) to depict both the processes of rational self-interest propensity and dishonesty conformity and examined their roles when people learn to act dishonestly. With an agent-based simulation and empirical studies of samples of diverse cultural backgrounds, we found that rational self-interest propensity was the primary factor driving the propagation of dishonest behaviors, whereas the effect of dishonesty conformity was conditional and context dependent. With an fMRI experiment, we found that the brain implemented dishonesty conformity distinctively when it served different goals. In addition, these two processes of dishonesty were encoded by various functional network architectures. In the background of the COVID-19 pandemic, where public coordination is in high demand but at the cost of self-interest, we found that these two processes of dishonesty exerted discrepant effects on residents’ attitudes toward local epidemic control and impacted the prevalence of pathogens unevenly.

In North America, members of Generation Z (people born since 1995) are facing struggles and obstacles that previous generations have not had to face, resulting in higher rates of depression and suicide and lower levels of life satisfaction. These struggles are likely to have a negative impact on the future generation of missionaries and mission organizations. Psychological struggles due to social media, addiction related to online gaming and pornography, and fragility due to changes in parenting and education have all been amplified by the COVID-19 pandemic. Moreover, these challenges may make North American Generation Z missionaries less effective unless mission structures change to provide the support and accountability necessary to minimize the effects of the new cultural context.

Since 2020, Indonesia has been facing the Covid-19 pandemic for 2 years. Many impacts caused by the Covid-19 pandemic, especially on the economy, have led to a recession. Regional revenues are disrupted during a recession so local governments depend on central government transfer funds. From these issues, researchers suspect that there was a change in the decentralization conditions in East Java province during the Covid-19 pandemic as it was the province with the second largest GDP and has also experienced the greatest impact in Indonesia. This research method uses multiple linear regression with cross-sectional data from 38 district/city data units in East Java province. The results of this study are that the Decentralization Fund, Civil Service Capital Expenditure and the Human Development Index did not change before and during the Covid-19 pandemic. While the vertical fiscal imbalance has a positive influence on economic growth before the Covid-19 pandemic, the vertical fiscal imbalance has no influence on economic growth. This shows that there is another shift in priority in the use of central government finances, as state money is refocused and reallocated to deal with Covid-19. This makes development programs in other health sectors postponed.

The aim of the current study was to explore whether the COVID-19 pandemic has affected people’s perceptions of other vaccines and diseases than COVID-19. In two samples of Finnish adults (N = 205 in Study 1 and N = 197 in Study 2), we longitudinally investigated whether there has been a change from before the COVID-19 pandemic to during the pandemic in: 1) influenza vaccination behavior and intentions, 2) the perceived benefit of childhood vaccines and influenza vaccines, 3) the perceived safety of childhood vaccines and influenza vaccines, 4) the perceived severity of measles and influenza, and 5) trust in health care professionals and health authorities in vaccine-related matters. The results indicated that more people had taken or had wanted to take the influenza vaccine during the pandemic than before. The respondents also considered influenza as more severe, and influenza vaccines as more beneficial and safe during the pandemic. For childhood vaccines, by contrast, there was only an increase in the perceived safety of the vaccines. Finally, in one of the studies, trust in health care professionals was higher during the pandemic than before. Taken together, these results suggest a spillover of the COVID-19 pandemic on people’s perceptions of other vaccines and diseases.

To further understand how to combat COVID-19 vaccination hesitancy, we examined the effects of pro-vaccine expert consensus messaging on lay attitudes about vaccine safety and intention to get a COVID-19 vaccine. We surveyed 729 unvaccinated individuals from four countries in the early stages of the pandemic, and 472 unvaccinated individuals from two countries after two years of the pandemic. We found belief of vaccine safety strongly correlated with intention to vaccinate in the first sample and less strongly in the second. We also found that consensus messaging improved attitudes toward vaccination even for participants who did not believe the vaccine is safe nor intended to get it. The persuasiveness of expert consensus was unaffected by exposing participants’ lack of knowledge about vaccines. We conclude that highlighting expert consensus may be a way to increase support toward COVID-19 vaccination in those hesitant or sceptical.

Abstract - The inpatient department or IPD is the dedicated unit of a hospital/healthcare facility for admitting patients from the OPD (outpatient department), ED (emergency department), or a referred patient usually from lower facilities for a planned care/procedure, for special medical problems that necessitate hospital admission for suitable care and consideration. The index case of SARS-CoV-2 virus infection in India was first suspected (based on clinical grounds) on 27th January 2020, an assumed case of covid-19 in Kerala with a that time recent voyage history of Wuhan, china was affirmed as SARS-CoV-2 virus infection positive case by the NIV (National Institute of Virology) situated at Pune in Maharashtra, on January 30th, 2020 as positive for COVID-19. As per the constitution of India Health is a subject matter of state, hence different states had reserved different percentages of beds in pre-existing health facilities for COVID-19 IPD patients, for example, the Delhi government had reserved 50% of pre-existing ICU (intensive care unit) and ward beds for COVID-19 IPD patient’s. Besides the other factors such as fear etc, this new arrangement of hospital care delivery and prioritization of needs of COVID-19 patients may have resulted in the general cancellations of other IPD patients elective procedures leading to a reduced IPD number of patients with diseases other than COVID-19, as priority was shifted to COVID-19 admitted patient’s and cases. The first author researcher of this study has found unusual prevalence in the figure of IPD (Inpatient Department) hospital admissions during his normal course of duties at health centres throughout the current ongoing COVID-19(coronavirus disease-2019) era. To know about the real scenario this epidemiological deductive study was done to confirm that, does the COVID-19 era have affected the number of IPD hospital admissions (positively or negatively) in India? The aim of this 41months comparative, quantitative, deductive, Cross-Sectional Research Study is to assess the impacts of COVID-19 on the prevalence of IPD hospital admissions in India (other than COVID-19), across all public/private/rural/urban health facilities of 36 states and union territories registered on HMIS (Health Management Information System) of Ministry of Health and Family Welfare (MoHFW), Government of India. The total mean number of IPD admissions for the 17 months (2020-2021) COVID-19 pandemic epoch, was 5387311 compared to 7435770 of IPD admission for the pre-pandemic 2 years (2018-2019). The total mean number of IPD admission decreased by 2048459 during the COVID-19 pandemic epoch i.e. 27.55% decrease is observed during COVID-19. This research study revealed that there is a significant decrease in IPD hospital admissions for various medical conditions other than COVID-19 during the COVID-19 pandemic epoch which is a matter of concern for policy and decision-makers.

<li><strong>Do Virtual Environments Close the Gender Gap in Participation in Question-and-Answer Sessions at Academic Conferences? In Search of Moderation by Conference Format</strong> -

Consistent with power and status differences between men and women in society, men tend to participate more than women do in question-and-answer (Q&A) sessions at in-person academic conferences. This gap in participation in scientific discourse may perpetuate the status quo. The current research examines whether this gender gap in participation in Q&A sessions extends to virtual conferences, which have become more prevalent during the COVID-19 pandemic. Due to shifts in conference formats to enable asynchronous, anonymous, and/or simultaneous participation, we examined whether virtual conferences are more inclusive, and mitigate the gender gap in Q&A participation. Across four virtual conferences that varied in gender representation and Q&A structured format, men continued to take a disproportionate amount of time and space in Q&A sessions. Disproportionate participation did not statistically significantly vary between in-person and virtual formats and did not systematically vary by how the Q&A session was organized. In an all-chat virtual conference, gender differences in volubility were attenuated among higher status academics. Gendered participation and volubility were also impacted by which sub-discipline the presentation was in. Discussion considers the theoretical and practical implications of these findings for understanding the persistence of gender inequality in science. We encourage future research that attends to the cultural factors that promote or mitigate gender disparities in participation.

Introduction An infodemic is an information epidemic capable of compromising public health. Based on the World Health Organization indications, this manuscript proposes an infoveillance method suitable for listening to web concerns on health in order to develop adequate infodemiological responses. In particular, the case of COVID-19 vaccinations in Italy was investigated. Methods Web interest and concern in COVID-19 vaccines over the past week (January 8 – 14, 2023) was investigated via the websites Google Trends and Talkwalker by searching for appropriate keywords. Thanks to the analysis of related queries and topics, it was possible to determine and examine the most debated topics relating to specific side effects. Results Emotional reactions regarding COVID-19 vaccines have been negative in varying percentages between 40 and 70%, depending on the topic discussed. Feelings of alarm, derision, doubt, and anger were common (about 60%). The concerns were mainly about the effectiveness against recent COVID-19 variants and alleged side effects such as sudden death, tumors, myocarditis, prion disease, and high ferritin. The most used media among those scrutinized was Twitter (over 90% of interactions). The male audience participated more and showed more negativity than the female one. The age groups mainly involved were the under-45s. Discussion and conclusion This research discussed the combined use of Google Trends and Talkwalker to conduct rapid infoveillance surveys. The results found showed that the web public has many doubts about COVID-19 vaccines, including the appearance of very rare or unproved side effects. Based on the WHO infodemic management strategy, it is essential that this or similar approaches are adopted by health and government authorities to listen to the community and calibrate appropriate infodemiological responses aimed at preserving public health.

<li><strong>APPRAISE: Fast, accurate ranking of engineered proteins by receptor binding propensity using structural modeling</strong> -
|

Deep learning-based methods for protein structure prediction have achieved unprecedented accuracy. However, the power of these tools to guide the engineering of protein-based therapeutics remains limited due to a gap between the ability to predict the structures of candidate proteins and the ability to assess which of those proteins are most likely to bind to a target receptor. Here we bridge this gap by introducing Automated Pairwise Peptide-Receptor AnalysIs for Screening Engineered proteins (APPRAISE), a method for predicting the receptor binding propensity of engineered proteins. After generating models of engineered proteins competing for binding to a target using an established structure-prediction tool such as AlphaFold2-multimer or ESMFold, APPRAISE performs a rapid (under 1 CPU second per model) scoring analysis that takes into account biophysical and geometrical constraints. As a proof-of-concept, we demonstrate that APPRAISE can accurately classify receptor-dependent vs. receptor-independent engineered adeno-associated viral vectors, as well as diverse classes of engineered proteins such as miniproteins targeting the SARS-CoV-2 spike protein, nanobodies targeting a G-protein-coupled receptor, and peptides that specifically bind to transferrin receptor and PD-L1. With its high accuracy, interpretability, and generalizability, APPRAISE has the potential to expand the utility of current structural prediction and accelerate protein engineering for biomedical applications.

<li><strong>Incipient parallel evolution of SARS-CoV-2 Deltacron variant in South Brazil</strong> -
|
|||
|
|
<div>
|

|
|
With the coexistence of multiple lineages and increased international travel, recombination and gene flow are likely to become increasingly important in the adaptive evolution of SARS-CoV-2. This could result in the incipient parallel evolution of multiple recombinant lineages. However, identifying recombinant lineages is challenging, and the true extent of recombinant evolution in SARS-CoV-2 may be underestimated. This study describes the first SARS-CoV-2 Deltacron recombinant case identified in Brazil. We demonstrate that the recombination breakpoint is at the beginning of Spike gene (S). The 5’ genome portion (circa 22 kb) resembles the AY.101 lineage (VOC Delta), and the 3’ genome portion (circa 8 kb nucleotides) is most similar to the BA.1.1 lineage (VOC Omicron). Furthermore, evolutionary genomic analyses indicate that the new strain emerged after a single recombination event between lineages of diverse geographical locations in December 2021 in South Brazil. This Deltacron, named AYBA-RS, is one out of almost 30 recombinants described this year. The submission of only four sequences in the GISAID database suggests that this Brazilian lineage had a minor epidemiological impact. On the other hand, the recent emergence of this and various other Deltacron recombinant lineages (i.e., XD, XF, and XS) suggests that gene flow and recombination may play an increasingly important role in the COVID-19 pandemic. We explain the evolutionary and population genetic theory that support this assertion, and we conclude that this stresses the need for continued genomic and epidemiological surveillance. This is particularly important for countries where multiple variants are present, as well as for countries that receive significant inbound international travel.

Introduction: The study objective was to elucidate the relationship between social vulnerability and COVID-19 impacts in Philadelphia between June 2020 and December 2022. Methods: Using publicly available COVID-19 case, test, hospitalization, and mortality data for Philadelphia (June 7, 2020-December 31, 2022) and area-level social vulnerability data, we compared the incidence, test positivity, hospitalization, and mortality rates in high and low vulnerability neighborhoods of Philadelphia, characterized as scoring above or below the national median score on the social vulnerability index. We used linear mixed effects models to test the association between social vulnerability and COVID-19 incidence, test positivity, hospitalization, and mortality rates, adjusting for time and age distribution. Results: 90.4% of Philadelphians (n = 1,430,153) live in neighborhoods classified as socially vulnerable, based on scoring above the national median score on the social vulnerability index. COVID-19 incidence, hospitalization, and mortality rates were significantly elevated in the more vulnerable communities, with p < 0.05, p < 0.005, and p < 0.001, respectively. The relative risks of COVID-19-related incidence, hospitalization, and death, comparing the more vulnerable neighborhoods to the less vulnerable neighborhoods, were 1.11 (95%CI: 1.10-1.12), 2.07 (95%CI: 1.93-2.20), and 2.06 (95%CI: 1.78-2.38), respectively. Thus, between June 7, 2020 and December 31, 2022, 32,573 COVID-19 cases, 9,409 hospitalizations, and 1,967 deaths would have been avoided in Philadelphias more vulnerable communities had they experienced the same rates of incidence, hospitalization, and death as the less vulnerable Philadelphia communities. Conclusions: These results highlight the disparate morbidity and mortality experienced by people living in more vulnerable neighborhoods in a large US city. Importantly, our findings illustrate the importance of designing public health policies and interventions with an equity-driven approach, with greater resources and more intensive prevention strategies applied in socially vulnerable communities.

Objective We aim to study the relationship between occupation distribution within each county and COVID-19 cumulative incidence and vaccination rate in the United States. Methods We collected county-level data from January 22, 2020 up to December 25, 2021. We fit multivariate linear models to find the relationship of the percentage of people employed by 23 main occupations. Results Counties with more health-related jobs, office support roles, community service, sales, production and material moving occupations had higher COVID-19 cumulative incidence. During the uptick of the Delta COVID variant (stratified period July 1-Dec 25), counties with more transportation occupations had significantly more COVID-19 cumulative incidence than before. Significance Understanding the association between occupations and COVID-19 cumulative incidence on an ecological level can provide information for precision public health strategies for prevention and protecting vulnerable workers.

The present work describes a statistical model to account for sequencing information of SARS-CoV-2 variants in wastewater samples. The model expresses the joint probability distribution of the number of genomic reads corresponding to mutations and non-mutations in every locus in terms of the variant proportions and the joint mutation distribution within every variant. Since the variant joint mutation distribution can be estimated using GISAID data, the only unknown parameters in the model are the variant proportions. These are estimated using maximum likelihood. The method is applied to monitor the evolution of variant proportions using genomic data coming from wastewater samples collected in A Coruna (NW Spain) in the period May 2021 - March 2022. Although the procedure is applied assuming independence among the number of reads along the genome, it is also extended to account for Markovian dependence of counts along loci in the aggregated information coming from wastewater samples.

High and equitable COVID-19 vaccination coverage is important for pandemic control and prevention of health inequity. However, little is known about socioeconomic correlates of booster vaccination coverage. In this cross-sectional study of all Norwegian adults in the national vaccination program (N = 4,190,655), we use individual-level registry data to examine coverage by levels of household income and education of primary (≥2 doses) and booster (≥3 doses) vaccination against COVID-19. We stratify the analyses by age groups with different booster recommendations and report relative risk ratios (RR) for vaccination by 25 August 2022. In the 18-44 years group, individuals with highest vs. lowest education had 94% vs. 79% primary coverage (adjusted RR (adjRR) 1.15, 95%CI 1.14-1.15) and 67% vs. 38% booster coverage (adjRR 1.55, 95% CI 1.55-1.56), while individuals with highest vs. lowest income had 94% vs. 81% primary coverage (adjRR 1.10, 95%CI 1.10-1.10) and 60% vs. 43% booster coverage (adjRR 1.23, 95%CI 1.22-1.24). In the ≥45 years group, individuals with highest vs. lowest education had 96% vs. 92% primary coverage (adjRR 1.02, 95%CI 1.02-1.02) and 88% vs. 80% booster coverage (adjRR 1.09, 95%CI 1.09-1.09), while individuals with highest vs. lowest income had 98% vs. 82% primary coverage (adjRR 1.16, 95%CI 1.16-1.16) and 92% vs. 64% booster coverage (adjRR 1.33, 95%CI 1.33-1.34). In conclusion, we document large socioeconomic inequalities in COVID-19 vaccination coverage, especially for booster vaccination, even though all vaccination was free-of-charge. The results highlight the need to tailor information and to target underserved groups for booster vaccination.

Efforts made to prevent transmission of the infectious agent that causes an infectious disease in its capacity as a pathogen are praised and victory is declared after the last case of the expected outcomes of the event in which this disease occurs is confirmed. After all, it is assumed that such expected outcomes of the event in which the pathogen causes the infectious disease are manifestations of this disease and therefore that the last confirmed case in which such outcomes are observed is the last case of infection. But the results obtained by visualizing the reality in which the immunological concepts which have eluded us since the birth of the repeatedly proven germ theory are represented reveal that outcomes of the event in which the pathogen causes the infectious disease are not manifestations of this disease but rather consequences of the co-manifestation of different diseases in the spectrum of the infectious disease. These results enable us to account for the differences between such outcomes which, for instance, in patients with COVID-19 that the current theory of infectious disease pathogenesis expects to produce outcomes that affect the upper respiratory disease, include unexpected conditions such as the chronic ones seen in Long COVID patients and in patients with mpox, which this theory logically deduced to be a skin-affecting disease, include deadly conditions like encephalitis with the consequence that outcomes with such deadly conditions are attributed to underlying conditions even after Spain’s health ministry reported deaths from such outcomes in healthy individuals. And the consequence of the same results is that the last cases of expected outcomes such as those that affect the skin of individuals who are infected with the mpox virus are not the last cases of infection but rather the last cases in which such outcomes appear as the sterile causes of the non-infectious diseases that co-manifest with the infectious disease for the emergence of such outcomes disappear from the population in which undetected spread of the infectious agent occurred long before the widespread appearance of such expected outcomes that called attention to this pathogen or an earlier form of the pathogen, such as the smallpox virus, which is assumed to have been eradicated. It follows in the reality which was visualized to obtain these results that even as the disappearance of such outcomes is being celebrated, the sterile causes of non-infectious diseases which co-manifest with the infectious disease for the emergence of unexpected deadly outcomes, such as those with encephalitis and toxic shock, may be appearing in the population which is already harboring the pathogen silently. And without exciting cause or warning, such deadly outcomes will become widespread in our populations and will decimate them if the only treatments available at the time are still those that reduce viral replication which are unable to bring about the remission of such outcomes. Instead of celebrating the disappearance of cases when the sterile causes of the non-infectious diseases that co-manifest with mpox for the emergence of those expected skin-affecting outcomes disappear, we ought to quickly elucidate the conditions that permit the immunological mechanisms of infection and vaccination to bring about uneventful exposure to such sterile causes even after deadly outcomes of such events have already appeared as achieved by the vaccines of William Coley and Julius Wagner-Jauregg in some cases even at a time when nothing was known about the nature of such immunological mechanisms and the remission that followed therapeutic infection in such cases was attributed to fever.
