The widespread deployment of social media has helped researchers access an enormous amount of data in various domains, including the the COVID-19 pandemic. This study draws on a heuristic approach to classify Commercial Instagram Posts (CIPs) and explores how the businesses around the Holy Shrine were impacted by the pandemic. Two datasets of Instagram posts (one gathered data from March 14th to April 10th, 2020, when Holy Shrine and nearby shops were closed, and one extracted data from the same period in 2019), two word embedding models – aimed at vectorizing associated caption of each post, and two neural networks – multi-layer perceptron and convolutional neural network – were employed to classify CIPs in 2019. Among the scenarios defined for the 2019 CIPs classification, the results revealed that the combination of MLP and CBoW achieved the best performance, which was then used for the 2020 CIPs classification. It was found out that the fraction of CIPs to total Instagram posts has increased from 5.58% in 2019 to 8.08% in 2020, meaning that business owners were using Instagram to increase their sales and continue their commercial activities to compensate for the closure of their stores during the pandemic. Moreover, the portion of non-commercial Instagram posts (NCIPs) in total posts has decreased from 94.42% in 2019 to 91.92% in 2020, implying the fact that since the Holy Shrine was closed, Mashhad residents and tourists could not visit it and take photos to post on their Instagram accounts.

In many countries, non-pharmaceutical interventions to limit SARS-CoV-2 transmission resulted in significant reductions in other respiratory viruses. However, similar data from Africa are limited. We explored the extent to which viruses such as influenza and rhinovirus co-circulated with SARS-CoV-2 in The Gambia during the COVID-19 pandemic. Between April 2020 and March 2022, respiratory viruses were detected using RT-PCR in nasopharyngeal swabs from 1397 participants with influenza-like illness. Overall virus positivity was 44.2%, with prevalence higher in children <5 years (80%) compared to children aged 5-17 years (53.1%), adults aged 18-50 (39.5%) and >50 years (39.9%), p<0.0001. After SARS-CoV-2 (18.3%), rhinoviruses (10.5%) and influenza viruses (5.5%) were the most prevalent. SARS-CoV-2 positivity was lower in children <5 (4.3%) and 5-17 years (12.7%) than in adults aged 18-50 (19.3%) and >50 years (24.3%), p<0.0001. In contrast, rhinoviruses were most prevalent in children <5 years (28.7%), followed by children aged 5-17 (15.8%), adults aged 18-50 (8.3%) and >50 years (6.3%), p<0.0001. Four SARS-CoV-2 waves occurred, with 36.1%-52.4% SARS-CoV-2 positivity during peak months. Influenza infections were observed in both 2020 and 2021 during the rainy season as expected (peak positivity 16.4%-23.5%). Peaks of rhinovirus were asynchronous to the months when SARS-CoV-2 and influenza peaked.

Stringency measures associated with governmental responses to COVID-19 have reportedly had varying effects on crime. As countries worldwide continue to remove restrictions there is concern related to post-COVID-19 restriction crime patterns. This study specifically examines the change in murder counts in Trinidad and Tobago pre, during and post-COVID-19 restrictions. Tie series analysis was used to assess non-linear trends and seasonality, while Date Time Warping was used to assess similarity between time periods. The results suggest that murder counts did decrease substantial during COVI-19 with 2020 having the lowest average murder count in a 8 year period. However, murder count have return to pre-COVID-19 levels in 2022, with all restrictions having been left in November 2021. It was concluded that while the exogenous shock caused by COVID-19 did decrease murders the effect was temporary. The removal of the treatment led to a return to the previous state of murders.

The COVID-19 pandemic has brought a lot of suffering to many people across the whole world. The disease not only directly devastated people’s health but also disrupted normal lifestyles and increased the risk of mental health issues [1,2]. A recent study by Kim et al. (2022) published in the Journal of Personalized Medicine (IF 3.508, according to JCR 2022) [3] revealed that the prevalence of stress, depression, and suicidal attempts did not change significantly during the COVID-19 pandemic compared to before. However, the 19- to 39-year-old group in the 2020 group had a higher rate of depression. The study employed data from the Korea National Health and Nutrition Examination Survey in 2019 and 2020, with a sample of >=19-year-old 11,873 participants. The research sample is highly representative of the Korean population.

<li><strong>Current Perception of Epidemic between Traditional and Social Media: an Italian Case Study</strong> -

Aim. More than two years after the beginning of the global epidemic period, most governments have adopted questionable strategies, aimed at the progressive reduction of the people freedom and pushing in a non-transparent way on the forced use of genic drugs, improperly called vaccines. The purpose of this work concerns the different way in which news relating to the epidemic reached citizens from traditional media (main TV channels and main national newspapers) and from social media, in particular from Telegram. Methods. The paper considers the situation perceived in Italy up to the first months of 2022 by analyzing the news appearing on mainstream TV channels and how they are described by national newspapers, as opposed to what can be deduced from some social media platforms who are still enough free from censorship. Results. The analysis underlines that there is a clear discrepancy between traditional and social media; the official narration of the traditional media is not only questionable, but does not give rise to the possibility of a free discussion on the hottest issues of this epidemic. Only Telegram appears to be the most censorship free channel among the studied traditional/social media in this paper. Conclusions. The attention placed on the official narrative of Covid-19, on the use of the methodology still in force in Italy for fighting the epidemic, on the strong nonsanitary limitation of individual freedom and on a possible underlying plan about what is globally happening leads to the conclusion that in Italy there is an attempt to give an ambiguous, equivocal and inconsistent version of the facts, contradicted by experimental data and scientific papers appearing more and more numerous in qualified international journals.

Background: Acute respiratory distress syndrome (ARDS), a life-threatening condition characterized by hypoxemia and poor lung compliance, is associated with high mortality. ARDS induced by COVID-19 has similar clinical presentations and pathological manifestations as non-COVID-19 ARDS. However, COVID-19 ARDS is associated with a more protracted inflammatory respiratory failure compared to traditional ARDS. Therefore, a comprehensive molecular comparison of ARDS of different etiologies groups may pave the way for more specific clinical interventions. Methods and Findings: In this study, we compared COVID-19 ARDS (n=43) and bacterial sepsis-induced (non-COVID-19) ARDS (n=24) using multi-omic plasma profiles covering 663 metabolites, 1,051 lipids, and 266 proteins. To address both between- and within- ARDS group variabilities we followed two approaches. First, we identified 706 molecules differently abundant between the two ARDS etiologies, revealing more than 40 biological processes differently regulated between the two groups. From these processes, we assembled a cascade of therapeutically relevant pathways downstream of sphingosine metabolism. The analysis suggests a possible overactivation of arginine metabolism involved in long-term sequelae of ARDS and highlights the potential of JAK inhibitors to improve outcomes in bacterial sepsis-induced ARDS. The second part of our study involved the comparison of the two ARDS groups with respect to clinical manifestations. Using a data-driven multi-omic network, we identified signatures of acute kidney injury (AKI) and thrombocytosis within each ARDS group. The AKI-associated network implicated mitochondrial dysregulation which might lead to post-ARDS renal-sequalae. The thrombocytosis-associated network hinted at a synergy between prothrombotic processes, namely IL-17, MAPK, TNF signaling pathways, and cell adhesion molecules. Thus, we speculate that combination therapy targeting two or more of these processes may ameliorate thrombocytosis-mediated hypercoagulation. Conclusion: We present a first comprehensive molecular characterization of differences between two ARDS etiologies: COVID-19 and bacterial sepsis. Further investigation into the identified pathways will lead to a better understanding of the pathophysiological processes, potentially enabling novel therapeutic interventions.

Building realistically complex models of infectious disease transmission that are relevant for informing public health is conceptually challenging and requires knowledge of coding architecture that can implement key modeling conventions. For example, many of the models built to understand COVID-19 dynamics have included stochasticity, transmission dynamics that change throughout the epidemic due to changes in host behavior or public health interventions, and spatial structures that account for important spatio-temporal heterogeneities. Here we introduce an R package, SPARSEMODr, that allows users to simulate disease models that are stochastic and spatially explicit, including a model for COVID-19 that was useful in the early phases of the epidemic. SPARSEMOD stands for <b>SPA</b>tial <b>R</b>esolution-<b>SE</b>nsitive <b>M</b>odels of <b>O</b>utbreak <b>D</b>ynamics, and our goal is to demonstrate particular conventions for rapidly simulating the dynamics of more complex, spatial models of infectious disease. In this report, we outline the features and workflows of our software package that allow for user-customized simulations. We believe the example models provided in our package will be useful in educational settings, as the coding conventions are adaptable, and will help new modelers to better understand important assumptions that were built into sophisticated COVID-19 models.

There is limited understanding of antibody responses in children across different SARS-CoV-2 variants. As part of an ongoing household cohort study, we assessed the antibody response among unvaccinated children infected with Wuhan, Delta or Omicron variants, as well as vaccinated children with breakthrough Omicron infection, using a SARS-CoV-2 S1-specific IgG assay and surrogate virus neutralisation test (sVNT). Most children infected with Delta (100%, 35/35) or Omicron (81.3%, 13/16) variants seroconverted by one month following infection. In contrast, 37.5% (21/56) children infected with Wuhan seroconverted, as previously reported. However, Omicron-infected children (GMC 46.4 BAU/ml; sVNT % inhibition: 16.3%) mounted a significantly lower antibody response than Delta (435.5 BAU/mL, sVNT=76.9%) or Wuhan (359.0 BAU/mL, sVNT=74.0%). Vaccinated children with breakthrough Omicron infection mounted the highest antibody response (2856 BAU/mL, sVNT=96.5%). Our findings suggest that despite a high seroconversion rate, Omicron infection in children results in lower antibody levels and function compared with Wuhan or Delta infection or with vaccinated children with breakthrough Omicron infection. Our data have important implications for public health measures and vaccination strategies to protect children.

The emergence of novel Omicron lineages, such as BA.5, may impact the therapeutic efficacy of anti-SARS-CoV-2 neutralizing monoclonal antibodies (mAbs). Here, we evaluated the neutralization and ADCC activity of 6 therapeutic mAbs against Delta, BA.2, BA.4 and BA.5 isolates. The Omicron sub-variants escaped most of the antibodies but remained sensitive to Bebtelovimab and Cilgavimab. Consistent with their shared spike sequence, BA.4 and BA.5 displayed identical neutralization profiles. Sotrovimab was the most efficient at eliciting ADCC. We also analyzed 121 sera from 40 immunocompromised individuals up to 6 months after infusion of 1200 mg of Ronapreve (Imdevimab + Casirivimab), and 300 or 600 mg of Evusheld (Cilgavimab + Tixagevimab). Sera from Ronapreve-treated individuals did not neutralize Omicron subvariants. Evusheld-treated individuals neutralized BA.2 and BA.5, but titers were reduced by 41- and 130-fold, respectively, compared to Delta. A longitudinal evaluation of sera from Evusheld-treated patients revealed a slow decay of mAb levels and neutralization. The decline was more rapid against BA.5. Our data shed light on the antiviral activities of therapeutic mAbs and the duration of effectiveness of Evusheld pre-exposure prophylaxis.

Establishment of long-lived plasma cells (PC) in the bone marrow (BM) is important for the development of long-term specific humoral immunity. While SARS-CoV-2-specific, resting, affinity-matured, IgG-secreting plasma cells were described in human bone marrow approx. 6-7 months after infection or vaccination, the long-term durability of these PC remains unclear. We here show that approximately 20% of SARS-CoV-2-specific human BM plasma cells, including RBD-specific PC accommodate the phenotype of long-lived plasma cells, characterized by the lack of CD19 and/or CD45. This result provides evidence in support of the emergence of persistent SARS-CoV-2 specific plasma cells in humans sustaining the durable production of specific serum IgG protecting against severe courses of COVID-19.

Individuals that receive a 3rd mRNA vaccine dose show enhanced protection against severe COVID19 but little is known about the impact of breakthrough infections on memory responses. Here, we examine the memory antibodies that develop after a 3rd or 4th antigenic exposure by Delta or Omicron BA.1 infection, respectively. A 3rd exposure to antigen by Delta breakthrough increases the number of memory B cells that produce antibodies with comparable potency and breadth to a 3rd mRNA vaccine dose. A 4th antigenic exposure with Omicron BA.1 infection increased variant specific plasma antibody and memory B cell responses. However, the 4th exposure did not increase the overall frequency of memory B cells or their general potency or breadth compared to a 3rd mRNA vaccine dose. In conclusion, a 3rd antigenic exposure by Delta infection elicits strain-specific memory responses and increases in the overall potency and breadth of the memory B cells. In contrast, the effects of a 4th antigenic exposure with Omicron BA.1 is limited to increased strain specific memory with little effect on the potency or breadth of memory B cell antibodies. The results suggest that the effect of strain-specific boosting on memory B cell compartment may be limited.

Introduction: Understanding the impact of lockdown upon RT, and how people adapted their RT behaviours, is expected to have implications for strategies to maintain engagement in positive health behaviours such as this during- restrictive pandemic-related public health measures. Further, doing so will provide a baseline for investigation of the long-term effects of these measures upon behaviours and perceptions and facilitate future follow-up study. Objectives: To determine how the onset of coronavirus (COVID-19), and the associated ‘lockdown’, affected resistance training (RT) behaviours, in addition to motivation, perceived effectiveness, enjoyment, and intent to continue, in those who regularly performed resistance training RT prior to the pandemic. Methods: We conducted an observational, cross-sectional study using online surveys in multiple languages (English, Danish, French, German, Italian, Portuguese, Slovakian, Swedish, and Japanese) distributed across social media platforms and through authors professional and personal networks. Adults (n = 5389 after data cleaning; median age = 31 years [interquartile range (IQR) = 25, 38]), who were previously engaged in RT prior to lockdown (median prior RT experience = 7 years [IQR = 4, 12]) participated. Outcomes were self-reported RT behaviours including: continuation of RT during lockdown, location of RT, purchase of specific equipment for RT, method of training (e.g. alone, supervision etc.), full-body or split routine, types of training, repetition ranges, exercise number, set volumes (per exercise and muscle group), weekly frequency of training, perception of effort, whether training was planned/recorded, time of day, and training goals. Secondary outcomes included motivation, perceived effectiveness, enjoyment, and intent to continue RT. Results: A majority of individuals (82.8%) maintained participation in some form of RT during- lockdown. Marginal probabilities from generalised linear models and generalised estimating equations of engaging in certain RT behaviours were largely similar from pre- to during- lockdown (particularly numbers of exercises, sets per exercise or muscle group, and weekly frequencies). There was reduced probability of training in privately owned gyms (~59% to ~7%) and increased probability of training at home (~18% to ~89%); greater probability of training using a full-body routine (~38% to ~51%); reduced probability of resistance machines (~66% to ~13%) and free weight use (~96% to ~81%), and increased probability of bodyweight training (~62% to ~82%); reduced probability of moderate repetition ranges (~62-82% to ~55-66%) and greater probability of higher repetition ranges (~27% to ~49%); and moderate reduction in the perception of effort experienced during- training (r = 0.31). Further, individuals were slightly less likely to plan or record training during- lockdown and many changed their training goals as a result of lockdown. Additionally, perceived effectiveness, enjoyment, and likelihood of continuing current training were all lower during- lockdown. Conclusions: Those engaged in RT prior to lockdown appeared mostly able to maintain these behaviours with only slight adaptations in both the location and types of training performed. However, people employed less effort, had lower motivation, and perceived training as less effective and enjoyable, reporting that their likelihood of continuing current training was similar or lower than pre- lockdown. These results have implications for strategies to maintain engagement in positive health behaviours such as RT during- restrictive pandemic-related public health measures.

Since the outbreak of the COVID-19 pandemic, the SARS-CoV-2 coronavirus accumulated an important amount of genome compositional heterogeneity through mutation and recombination, which can be summarized by means of a measure of Sequence Compositional Complexity (SCC). To test evolutionary trends that could inform us on the adaptive process of the virus to its human host, we compute SCC in high-quality coronavirus genomes from across the globe, covering the full span of the pandemic. By using phylogenetic ridge regression, we find trends for SCC in the short time-span of SARS-CoV-2 pandemic expansion. In early samples, we find no statistical support for any trend in SCC values over time, although the virus genome appears to evolve faster than Brownian Motion expectation. However, in samples taken after the emergence of Variants of Concern with higher transmissibility, and controlling for phylogenetic and sampling effects, we detect a declining trend for SCC and an increasing one for its absolute evolutionary rate. This means that the decay in SCC itself accelerated over time, and that increasing fitness of variant genomes lead to a reduction of their genome sequence heterogeneity. Therefore, our work shows that phylogenetic trends, typical of macroevolutionary time scales, can be also revealed on the shorter time spans typical of viral genomes.

<li><strong>Measuring and validating spatial accessibility to Covid-19 vaccination sites: a case study in England</strong> -

The global Covid-19 pandemic has caused numerous deaths and illnesses and posed unprecedented social and economic challenges to many countries. One of the key strategies to contain the pandemic is mass vaccination. While it is essential to ensure safe and easy accessibility to Covid-19 vaccines for all communities, limited research has been carried out to understand and validate the spatial accessibility of these vaccines. This study addresses this gap by measuring and validating the spatial accessibility to Covid-19 vaccines with a particular focus on England, United Kingdom. More specifically, we compare three floating catchment area (FCA) methods with differing parameters for measuring the small-scale spatial accessibility to vaccination services. Then, we calibrate these accessibility measurements using a beta regression model and the reported vaccination uptake rates. The results show that the three-step FCA method with a distance parameter of 30 miles is the optimal model for measuring the spatial accessibility to Covid-19 vaccines. The findings provide an improved understanding of the spatial inequality of vaccine services. Further, the framework of calibrating spatial accessibility to vaccine services is generalisable to other types of healthcare services.

<li><strong>Resuming Social Contact After Months of Contact Restrictions: Social Traits Moderate Associations Between Changes in Social Contact and Well-Being</strong> -

Humans possess a need for social contact. Satisfaction of this need benefits well-being, whereas deprivation is detrimental. However, how much contact people desire is not universal, and evidence is mixed on individual differences in the association between contact and well-being. This preregistered longitudinal study (N = 190) examined changes in social contact and well-being (life satisfaction, depressivity/anxiety) in Germany during pervasive contact restrictions, which exceed lab-based social deprivation. We analyzed how changes in personal and indirect contact and well-being during the first COVID-19 lockdown varied with social traits (e.g., affiliation, extraversion). Results showed that affiliation motive, need to be alone, and social anxiety moderated the resumption of personal contact under loosened restrictions as well as associated changes in life satisfaction and depressivity/anxiety.
