<li><strong>Reactance and perceived disease severity as determinants of COVID-19 vaccination intention: An application of the theory of planned behavior</strong> -

Vaccination is crucial in fighting the COVID-19 pandemic. To encourage as many people as possible to be vaccinated, it is essential to identify the determinants of COVID-19 vaccination intention. The present study aimed to do so through an application of the theory of planned behavior (TPB). We examined variables associated with TPB, perceived severity of COVID-19, knowing someone afflicted with COVID-19, and individual differences, such as age, gender, and psychological reactance, among 551 Polish participants. Attitude (utility beliefs) toward COVID-19 vaccination was the strongest predictor of vaccination intention, followed by beliefs about social norms and perceived behavioral control. Older age and knowing someone with COVID-19 led to higher vaccination intention through perceived higher severity of the infection, and higher levels of all TPB components, compared with other participants. Being a woman and having higher trait reactance negatively affected COVID-19 vaccination intention through lower levels of all TPB components. The results show that COVID-19 vaccination intention is directly determined by all TPB components, and is affected by gender, age, COVID-19-related variables, and reactance. Our results contribute to the scientific pursuit of encouraging uptake of the COVID-19 vaccine by identifying modifiable determinants that could be targeted in health promotion campaigns.

Asian Americans became targets of increasingly hostile behavior during the COVID-19 pandemic. What motivated this? Fears of contagion arising from a behavioral immune system (BIS) may have motivated differential treatment towards Chinese-born US residents, especially early in the pandemic and among those vulnerable to COVID-19. On the other hand, rhetoric from right-wing media figures may have legitimated anti-Asian behavior. We explore these questions using a behavioral game with a representative sample of Americans at two points: in spring and fall 2020. Participants were partnered with a US- or Chinese-born US resident. The average American treated Chinese-born US residents worse compared to US-born residents in the spring but not the fall, when China was no longer a COVID-19 hotspot. But among Republicans, likely more receptive to right-wing rhetoric, unequal treatment was both stronger in the spring and persisted into the fall.

In a recent contribution, Subramanian and Kumar (2021) state that increases in COVID-19 are unrelated to vaccination rates both across countries and across U.S. counties. I first discuss several empirical challenges related to the estimation of a meaningful relationship between these two variables which Subramanian and Kumar (2021) do not address. Using the same data sources, I then show that their findings disappear once the longitudinal character of the data is being utilized, underlining the arbitrary character of their result. Finally, I highlight that some of the county-level vaccination rates that Subramanian and Kumar (2021) cite as benchmarks for highly vaccinated locations are implausible and contradicted by additional data sources.

<li><strong>Loss of Neutralizing Antibody Response to mRNA Vaccination against SARS-CoV-2 Variants: Differing Kinetics and Strong Boosting by Breakthrough Infection</strong> -

<div>
|

|
|
The waning efficacy of SARS-CoV-2 vaccines combined with the continued emergence of variants resistant to vaccine- induced immunity has reignited debate over the need for booster vaccines. To address this, we examined the neutralizing antibody (nAb) response against four major SARS-CoV-2 variants–D614G, Alpha (B.1.1.7), Beta (B.1.351), and Delta (B.1.617.2)–in health care workers (HCWs) at pre-vaccination, post-first and post-second mRNA vaccine dose, and six months post-second mRNA vaccine dose. Neutralizing antibody titers against all variants, especially the Delta variant, declined dramatically from four weeks to six months post-second mRNA vaccine dose. Notably, SARS-CoV-2 infection enhanced vaccine durability, and mRNA-1273 vaccinated HCWs also exhibited ~2-fold higher nAb titers than BNT162b2 vaccinated HCWs. Together these results demonstrate possible waning of protection from infection against SARS-CoV-2 Delta variant based on decreased nAb titers, dependent on COVID-19 status and the mRNA vaccine received.

Ribonucleic acid (RNA) viruses pose heavy burdens on public-health systems. Synthetic biology holds great potential for artificially controlling their replication, a strategy that could be used to attenuate infectious viruses but is still in the exploratory stage. Herein, we used the genetic-code expansion technique to convert Enterovirus 71 (EV71), a model of RNA virus, into a controllable EV71 strain carrying the unnatural amino acid (UAA) N{varepsilon}-2-azidoethyloxycarbonyl-L-lysine (NAEK), which we termed an EV71-NAEK virus. EV71-NAEK could recapitulate an authentic NAEK time- and dose-dependent infection in vitro and in vivo, which could serve as a novel method to manipulate virulent viruses in conventional laboratories. We further validated the prophylactic effect of EV71-NAEK in two mouse models. In susceptible parent mice, vaccination with EV71-NAEK elicited a strong immune response and potentially protected their neonatal offspring from lethal challenge similar to that of commercial vaccines. Meanwhile, in transgenic mice harboring a PylRS-tRNAPyl CUA pair, substantial elements of genetic-code expansion technology, EV71-NAEK evoked an adjustable neutralizing-antibody response in a strictly external NAEK dose-dependent manner. These findings suggested that EV71-NAEK could be the basis of a feasible immunization program for populations with different levels of immunity. Moreover, we expanded the strategy to generate controllable coxsackieviruses and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for conceptual verification. In combination, these results could underlie a competent strategy for attenuating viruses and priming the immune system via artificial control, which might be a promising direction for the development of amenable vaccine candidates and be broadly applied to other RNA viruses.

Background In locations where few people have received COVID-19 vaccines, health systems remain vulnerable to surges in SARS-CoV-2 infections. Tools to identify patients suitable for community-based management are urgently needed. Methods We prospectively recruited adults presenting to two hospitals in India with moderate symptoms of laboratory- confirmed COVID-19 in order to develop and validate a clinical prediction model to rule-out progression to supplemental oxygen requirement. The primary outcome was defined as any of the following: SpO2 < 94%; respiratory rate > 30 bpm; SpO2/FiO2 < 400; or death. We specified a priori that each model would contain three clinical parameters (age, sex and SpO2) and one of seven shortlisted biochemical biomarkers measurable using near-patient tests (CRP, D-dimer, IL-6, NLR, PCT, sTREM-1 or suPAR), to ensure the models would be suitable for resource-limited settings. We evaluated discrimination, calibration and clinical utility of the models in a temporal external validation cohort. Findings 426 participants were recruited, of whom 89 (21·0%) met the primary outcome. 257 participants comprised the development cohort and 166 comprised the validation cohort. The three models containing NLR, suPAR or IL-6 demonstrated promising discrimination (c-statistics: 0·72 to 0·74) and calibration (calibration slopes: 1·01 to 1·05) in the validation cohort, and provided greater utility than a model containing the clinical parameters alone. Interpretation We present three clinical prediction models that could help clinicians identify patients with moderate COVID-19 suitable for community- based management. The models are readily implementable and of particular relevance for locations with limited resources. Funding M&eacutedecins Sans Fronti&egraveres, India.

Estimating an infectious disease attack rate requires inference on the number of reported symptomatic cases of a disease, the number of unreported symptomatic cases, and the number of asymptomatic infections. Population-level immunity can then be estimated as the attack rate plus the number of vaccine recipients who had not been previously infected; this requires an estimate of the fraction of vaccines that were distributed to seropositive individuals. To estimate attack rates and population immunity in southern New England, we fit a validated dynamic epidemiological model to case, clinical, and death data streams reported by Rhode Island, Massachusetts, and Connecticut for the first 15 months of the COVID-19 pandemic, from March 1 2020 to May 31 2021. This period includes the initial spring 2020 wave, the major winter wave of 2020-2021, and the lagging wave of lineage B.1.1.7(Alpha) infections during March-April 2021. In autumn 2020, SARS-CoV-2 population immunity (equal to the attack rate at that point) in southern New England was still below 15%, setting the stage for a large winter wave. After the roll-out of vaccines in early 2021, population immunity in many states was expected to approach 70% by spring 2021, with more than half of this immune population coming from vaccinations. Our population immunity estimates for May 31 2021 are 73.4% (95% CrI: 72.9% - 74.1%) for Rhode Island, 64.1% (95% CrI: 64.0% - 64.4%) for Connecticut, and 66.3% (95% CrI: 65.9% - 66.9%) for Massachusetts, indicating that >33% of southern Englanders were still susceptible to infection when the Delta variant began spreading in July 2021. Despite high vaccine coverage in these states, population immunity in summer 2021 was lower than planned due to 34% (Rhode Island), 25% (Connecticut), and 28% (Massachusetts) of vaccine distribution going to seropositive individuals. Future emergency-setting vaccination planning will likely have to consider over-vaccination as a strategy to ensure that high levels of population immunity are reached during the course of an ongoing epidemic.

Objective: In this large multi-institutional study, we aimed to analyze the prognostic power of computed tomography (CT)-based radiomics models in COVID-19 patients. Methods: CT images of 14,339 COVID-19 patients with overall survival outcome were collected from 19 medical centers. Whole lung segmentations were performed automatically using a previously validated deep learning-based model, and regions of interest were further evaluated and modified by a human observer. All images were resampled to an isotropic voxel size, intensities were discretized into 64-binning size, and 105 radiomics features, including shape, intensity, and texture features were extracted from the lung mask. Radiomics features were normalized using Z-score normalization. High-correlated features using Pearson (R2>0.99) were eliminated. We applied the Synthetic Minority Oversampling Technique (SMOT) algorithm in only the training set for different models to overcome unbalance classes. We used 4 feature selection algorithms, namely Analysis of Variance (ANOVA), Kruskal-Wallis (KW), Recursive Feature Elimination (RFE), and Relief. For the classification task, we used seven classifiers, including Logistic Regression (LR), Least Absolute Shrinkage and Selection Operator (LASSO), Linear Discriminant Analysis (LDA), Random Forest (RF), AdaBoost (AB), Naive Bayes (NB), and Multilayer Perceptron (MLP). The models were built and evaluated using training and testing sets, respectively. Specifically, we evaluated the models using 10 different splitting and cross-validation strategies, including different types of test datasets (e.g. non- harmonized vs. ComBat-harmonized datasets). The sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC) were reported for models evaluation. Results: In the test dataset (4301) consisting of CT and/or RT-PCR positive cases, AUC, sensitivity, and specificity of 0.83(sd:0.01) (CI95%: 0.81-0.85), 0.81, and 0.72, respectively, were obtained by ANOVA feature selector + RF classifier. In RT-PCR-only positive test sets (3644), similar results were achieved, and there was no statistically significant difference. In ComBat harmonized dataset, Relief feature selector + RF classifier resulted in highest performance of AUC, reaching 0.83 (sd:0.01) (CI95%: 0.81-0.85), with sensitivity and specificity of 0.77 and 0.74, respectively. At the same time, ComBat harmonization did not depict statistically significant improvement relevant to non-harmonized dataset. In leave-one-center-out, the combination of ANOVA feature selector and LR classifier resulted in the highest performance of AUC (0.80 (sd:0.084)) with sensitivity and specificity of 0.77 (sd:0.11) and 0.76 (sd: 0.075), respectively. Conclusion: Lung CT radiomics features can be used towards robust prognostic modeling of COVID-19 in large heterogeneous datasets gathered from multiple centers. As such, CT radiomics-based model has significant potential for use in prospective clinical settings towards improved management of COVID-19 patients.

The Covid-19 pandemic has brought the World to a near standstill for most of 2020 and 2021, causing chaos in international travel, driving many economies into the ground, particularly those largely based on tourism. The lack of standard tools to assist decision makers in structuring a coherent policy to allow foreign passengers into their county and the resulting panic-mode opening/closing the borders on every ″new case″ outburst or new variant ″of concern″, have led several countries to costly and often meaningless decisions based on fear rather than science or logic. This study aims at providing a universal method to safely keep the borders open and allow conditional immigration to foreign passengers according to a ″Risk Group″ table that includes all the countries reporting data on their Covid-19 situation to the WHO and other organisms. The RG table is recalculated on a weekly basis according to a mathematical model described in this paper, dynamically assessing the status of the pandemic worldwide through the calculation of a ″Safety Index″ for each country. A prototype algorithm has been implemented in VBA/EXCEL and its results are published bi- weekly on a Github repository.

For some countries that have experienced numerous natural disasters, including massive earthquakes and tsunamis, managing the COVID-19 pandemic can be very challenging. This situation arises considering that the disaster can directly and indirectly affect the healthcare system9s capacity to serve the COVID-19 cases. With severely damaged healthcare facilities due to the disaster, there will be severely ill COVID-19 cases unmanaged. The coupling and interplay between these two phenomena can indeed be catastrophic. One of the regions where this issue becomes concerned is in Southeast Asia, where most of the Asian countries lie in the fragile ring of fire ecosystem, contributing to the high tsunami and earthquake disasters in the world. At the same time, Asia is one of the regions that have been severely impacted due to the current COVID-19 Delta Variant. Recently, a more contagious Omicron Variant has emerged and put a more massive burden on the healthcare facilities that are impacted by disasters. Then, in this situation, this paper aims to assess healthcare resilience in managing the Omicron pandemic amid disaster impacts. SIR simulation was used to determine whether severely ill Omicron cases were below or above healthcare and ICU capacity under different vaccination coverage. Our result confirms that vaccination coverage was the imminent factor in reducing the severely ill cases in every healthcare facility, whether the facilities were damaged or not. Increasing vaccination coverage from 30% to 60% will significantly reduce the number of severely ill cases that fall below the capacity of healthcare. Based on the current SIR model on the Omicron epidemic variables and Ro, it is estimated that the Omicron will reach its peak after 180 days in February 2022 and will totally disappear in May 2022 in this modeled area. When healthcare system facilities were fully operational and no disaster happened, combined with 60% vaccination rates, all Omicron case numbers were below and under the available hospital beds and even available ICU beds. While the situation is changed when a disaster occurs and causes 30% damage or reduction to healthcare facilities. In this situation, there are portions of Omicron cases that cannot be managed by the healthcare system since the cases have exceeded the available beds. The situations become more apparent where the healthcare facilities are severely damaged and lose 60% of their functionality. In this situation, all modeled Omicron cases and even the severe cases have exceeded the ICU capacity.

Heterogeneity in susceptibility among individuals to COVID-19 has been evident through the pandemic worldwide. Protective cytotoxic T lymphocyte (CTL) responses generated against pathogens in certain individuals are known to impose selection pressure on the pathogen, thus driving emergence of new variants. In this study, we focus on the role played by host genetic heterogeneity in terms of HLA-genotypes in determining differential COVID-19 severity in patients and dictating mechanisms of immune evasion adopted by SARS-CoV-2 due to the imposed immune pressure at global and cohort levels. We use bioinformatic tools for CTL epitope prediction to identify epitopes under immune pressure. Using HLA- genotype data of COVID-19 patients from a local cohort, we observe that asymptomatic individuals recognize a larger number of pressured epitopes which could facilitate emergence of mutations at these epitopic regions to overcome the protectivity they offer to the host. Based on the severity of COVID-19, we also identify HLA-alleles and epitopes that offer higher protectivity against severe disease in infected individuals. Finally, we shortlist a set of pressured and protective epitopes that represent regions in the viral proteome that are under higher immune pressure across SARS-CoV-2 variants due to the protectivity they offer. Identification of such epitopes could potentially aid in prediction of indigenous variants of SARS-CoV-2 and other pathogens, defined by the distribution of HLA-genotypes among members of a population.

Background Reports of myocarditis and pericarditis following vaccination with mRNA vaccines for SARS-CoV-2 have occurred after countries began vaccinating adolescents. We undertook a systematic review of cardiac adverse effects associated with SARS-CoV-2 vaccine in children and young people (CYP)< 18 years. Methods Systematic review with protocol prospectively registered with PROSPERO (CRD42021275380). Six electronic databases were searched from 1 December 2019 to 14 September 2021. Eligible studies were those reporting on CYP with reported or proven myocarditis, pericarditis and/or myopericarditis associated with vaccination against SARS-CoV-2. We summarized findings across all clinical cases reported in case report / case series studies. As a number of studies reported data from two publicly available vaccine surveillance systems, we updated estimates of reporting rates for cardiac adverse events up to 31 October for the US Vaccine Adverse Event Reporting System (VAERS) and 13 November for EudraVigilance covering European Union and European Economic Area (EUEA) countries. Results Twenty-one studies were included from 338 identified records. Seventeen were case re-ports/series describing a total of 127 CYP. Three studies described reporting rates from passive surveillance databases (VAERS, EudraVigilance, and the WHO VigiBase) and one de-scribed 22 cases from the US Vaccine Safety Datalink (VSD). Clinical series reported that 99.2% presented with chest pain, 100% had raised troponin and 73.8% had an abnormal ECG. Cardiovascular magnetic resonance (CMR) in 91 cases identified myocardial injury in 61.5%, with 90.1% showing late gadolinium enhancement. NSAIDs were the most common treatment (76.0%). One US dataset (VSD) estimated a significant excess of 29.6 events per million vaccine doses across both sexes and doses. There were 1129 reports of myocarditis and 358 reports of pericarditis from across the USA and EU/EEA. The VAERS reporting rate per million for myocarditis was 12.4 for boys and 1.4 for girls after the first dose, and 49.6 for boys and 6.1 for girls after the second dose. There was a marked trend for VAERS reporting to be highest soon after initiation of the vaccine schedule, suggesting reporting bias. Conclusions Cardiac adverse effects are very rare after mRNA vaccination for COVID-19 in CYP <18 years. The great majority of cases are mild and self-limiting without significant treatment. No data are yet available on children under 12 years. Larger detailed longitudinal studies are urgently needed from active surveillance sources.

Symptoms after SARS-CoV-2 primary vaccination among patients with inflammatory bowel disease (IBD) are generally of similar frequency, severity, and duration to those reported in the general population. The symptom profile after a 3rd mRNA vaccine dose in the predominantly immune-compromised IBD population is unknown. We aimed to assess symptomology after a 3rd or booster dose of mRNA vaccination in adults with IBD. We surveyed participants of the Coronavirus Risk Associations and Longitudinal Evaluation in IBD (CORALE-IBD) post-vaccination registry for symptom frequency and severity after a 3rd mRNA vaccine dose in an observational cohort study. In total, 524 participants (70% female, mean age 45 years) reported a third dose of mRNA vaccination through October 11, 2021. Overall, 41% reported symptoms after a third dose, with symptoms generally more frequent and more severe among participants younger than 55 years. The most frequent postvaccination symptoms were injection site pain (39%), fatigue or malaise (34%), and headache (23%). These symptoms were all less frequently reported after dose 3 than after dose 2. Gastrointestinal symptoms were reported by 8.8%, which was slightly more frequent than after dose 2 (7.8%). Those with severe symptoms after dose 2 were more likely to have severe symptoms after dose 3. These findings can reassure the IBD patient and provider communities that the likelihood and distribution of symptoms after a third mRNA vaccine dose are generally similar to those after a second dose, and that the frequency of postvaccination symptoms after dose 3 are generally lower than after dose 2.

The inclusion of the human mobility aspect is essential for understanding the behavior of COVID-19 spread, especially when millions of people travel across borders near Eid Al-Fitr. This study aims at grasping the effect of mass exodus among regions on the active cases of COVID-19 in a mathematical perspective. We construct a multi-region SIQRD (Susceptible-Infected-Quarantined-Recovered-Death) model that accommodates the direct transfer of people from one region to another. The mobility rate is estimated using the proposed Dawson-like function, which requires the Origin- Destination Matrix data. Assuming only susceptible, unapparent infected, and recovered individuals travel near Eid Al- Fitr, the rendered model is well-depicting the actual data at that time, giving either a significant spike or decline in the number of active cases due to the mass exodus. Most agglomerated regions like Jakarta and Depok City experienced the fall of active cases number, both in actual data and the simulated model. However, most rural areas experienced the opposite, like Bandung District and Cimahi City. This study should confirm that most travelers originated from big cities to the rural regions and scientifically justifies that massive mobility affects the COVID-19 transmission among areas.

SARS-CoV-2 remdesivir resistance mutations have been generated in vitro but have not been reported in patients receiving treatment with the antiviral agent. We present a case of an immunocompromised patient with acquired B-cell deficiency who developed an indolent, protracted course of SARS-CoV-2 infection. Remdesivir therapy alleviated symptoms and produced a transient virologic response, but her course was complicated by recrudescence of high-grade viral shedding. Whole genome sequencing identified a mutation, E802D, in the nsp12 RNA-dependent RNA polymerase which was not present in pre-treatment specimens. In vitro experiments demonstrated that the mutation conferred a ~6-fold increase in remdesivir IC50 but resulted in a fitness cost in the absence of remdesivir. Sustained clinical and virologic response was achieved after treatment with casirivimab-imdevimab. Although the fitness cost observed in vitro may limit the risk posed by E802D, this case illustrates the importance of monitoring for remdesivir resistance and the potential benefit of combinatorial therapies in immunocompromised patients with SARS-CoV-2 infection.

<li><p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom"><strong>A study of contemporary trends in investing patterns, household savings, and economic investment.</strong> - Because household savings and household investments are intertwined and interdependent, they are discussed briefly in this paper. Household savings account for more than half of a country’s capital formation, which fluctuates due to a variety of economic factors such as inflation and interest rates. Households should gradually shift their savings and investments from physical assets to financial assets to avoid a sudden change in wealth. They should also save and invest using a variety of platforms. Trends in investing and saving will be easier to track and measure this way. This year’s domestic saving rate in India is 2.3 percent lower than last year’s and 1.2 percent lower than the year before. Since 2011, general domestic savings have been steadily declining, with the trend continuing into the following year. According to official data, the GDP in 2020 shrank by 23.9%, the least in previous years and the least since the Covid-19 pandemic in previous years. As a result, the information presented in this paper is drawn from and evaluated from other sources - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN340502149">link</a></p></li>
