<li><strong>Prediction of residue-specific contributions to binding and thermal stability using yeast surface display</strong> -
|
||
<div>
|
||
Accurate prediction of residue burial as well as quantitative prediction of residue-specific contributions to protein stability and activity is challenging, especially in the absence of experimental structural information. This is important for prediction and understanding of disease causing mutations, and for protein stabilization and design. Using yeast surface display of a saturation mutagenesis library of the bacterial toxin CcdB, we probe the relationship between ligand binding and expression level of displayed protein, with in vivo solubility in E.coli and in vitro thermal stability. We find that both the stability and solubility correlate well with the total amount of active protein on the yeast cell surface but not with total amount of expressed protein. We coupled FACS and deep sequencing to reconstruct the binding and expression mean fluorescent intensity of each mutant. The reconstructed mean fluorescence intensity (MFIseq) was used to differentiate between buried site, exposed non active-site and exposed active-site positions with high accuracy. The MFIseq was also used as a criterion to identify destabilized as well as stabilized mutants in the library, and to predict the melting temperatures of destabilized mutants. These predictions were experimentally validated and were more accurate than those of various computational predictors. The approach was extended to successfully identify buried and active-site residues in the receptor binding domain of the spike protein of SARS-CoV-2, suggesting it has general applicability.

<li><strong>COVID-19 and Seasonal Flu Vaccination Hesitancy: Links to Personality and General Intelligence in a Large, UK Cohort</strong> -
|
||
<div>
|
||
Vaccines are a powerful and relatively safe tool to protect against a range of serious diseases. Nonetheless, a sizeable minority of people express ‘vaccination hesitancy’. Accordingly, understanding the bases of this hesitancy represents a significant public health challenge. In the present study we sought to examine the role of Big Five personality traits and general intelligence as predictors of vaccination hesitancy, across two vaccination types, in a large (N= 9667) sample of UK adults drawn from the Understanding Society longitudinal household study. We found that lower general intelligence was associated with COVID-19 and seasonal flu vaccination hesitancy, and lower neuroticism was associated with COVID-19 vaccination hesitancy. Although the self-reported reasons for being vaccine hesitant indicated a range of factors were important to people, lower general intelligence was associated with virtually all of these reasons. In contrast, Big 5 personality traits showed more nuanced patterns of association. These findings provide important insights into vaccination hesitancy and help to reconcile some of the inconsistencies found in previous literature.

<li><strong>EVALUATION OF EFFECTIVENESS OF AROGYA KASHAYAM-20 IN COVID-19 CASES - A RANDOMIZED CONTROLLED STUDY</strong> -
|
||
<div>
|
||
Introduction: The characteristic clinical features of Covid-19 disease range between asymptomatic to mild-moderate symptoms. Studies suggest that a large population (80%) presents its asymptomatic or milder form. Remaining 20 percent, owing to severity of the diseases, need hospital-based care. Many treatment protocols and strategies have been promoted and recommended by authorities including WHO, but nothing has actually been finalized till date. The present study was planned to evaluate the effectiveness of an Ayurvedic formulation viz. Arogya Kashayam-20 in the hospitalized cases of Covid-19. Aim: To evaluate the effectiveness of Arogya Kashayam-20 in the cases of COVID-19 particularly the negative conversion of RTPCR in 10 days duration. Material and Methods: This was a randomized controlled trial conducted at COVID-19 Care Center, Pt. Khushilal Sharma Government Ayurveda College & Institute, Bhopal, Madhya Pradesh with a sample size of 112 participants, aged between 16 to 60 years of either sex. Participants were divided in two groups viz. group A and B. Both the groups received Hydroxychloroquine (HCQ), vitamin C and Zinc as per the prevailing ICMR guidelines and group ‘A’ received additionally Arogya Kashayam-20 for 10 days. Outcome measure of the study was to see the negative conversion RT-PCR test after intervention period of 10 days. CTRI Registration: CTRI/2020/06/026221. Results: Among the 60 cases registered in study group (group A), 51 cases (85.00%) were reported with negative RTPCR on 10th day. Out of 52 cases registered in control group (group B); 39 cases (75.00%) were tested negative RTPCR on 10th day. In both the groups all the cases were discharged asymptomatically on 10th day as per the prevailing ICMR guidelines. No ADR/AE observed during the intervention period. Conclusion: The study observes that the add on intervention group has a better outcome in terms of RT-PCR negative reports after 10 days comparing to the control group.

<li><strong>Social cohesion at the outset of COVID-19 predicts later vaccination intentions</strong> -
|
||
<div>
|
||
Vaccination intentions are widely regarded as individual decision, resting upon individuals’ attitudes and beliefs about the disease and their own health. In this research, we provide evidence that group factors, and more precisely, social cohesion — a multidimensional concept that encompasses one’s sense of connectedness to, and interrelations within, a group — can help us understand COVID-19 vaccination intentions. Using a representative sample of 3026 Australians, we first found evidence for the multidimensional structure of social cohesion, as a concept that includes positive social relations, social identification, and trust in government. Second, social cohesion assessed early in the COVID-19 pandemic predicted greater vaccination intention and lower perceived risk of vaccination four months later, after controlling for a series of demographic (i.e., sex, age, income) and health-related factors (i.e., subjective health; perceived risk; having been diagnosed with COVID-19). These results suggest that investments in social cohesion could have substantial and unexpected downstream benefits.

|
||
<div>
|
||
The COVID-19 pandemic has caused an exponential increase in the demand for medical care worldwide. In Mexico, the COVID Medical Units (CMU) conversion strategy was implemented. Objective. To evaluate the CMU coverage strategy in the Mexico City Metropolitan Area (MCMA) by territory. Materials. The CMU directory was used, as were COVID-19 infection and movement statistics and 2020 Mexican census information at the urban geographic area scale. The degree of urban marginalization by geographic area was also considered. Method. Using descriptive statistics and the calculation of a CMU accessibility index, population aggregates were counted based on coverage radii. In addition, two regression models are proposed to explain 1) the territorial and temporal trend of COVID-19 infections in the MCMA and 2) the movement of the COVID-infected population to medical units. Results. The findings of the evaluation of the CMU strategy were 1) in the MCMA, COVID-19 followed a pattern of contagion from the urban center to the periphery; 2) given the growth in the number of cases and the overload of medical units, the population traveled greater distances to seek medical care; 3) after the CMU strategy was evaluated at the territory level, it was found that 9 out of 10 inhabitants had a CMU located approximately 7 kilometers away; and 4) at the metropolitan level, the lowest level of accessibility to the CMU was recorded for the population with the highest levels of marginalization: those residing in the urban periphery.

<li><strong>A novel Pan-viral prophylaxis strategy using vaccine adjuvant CAF09b protects against influenza virus infection</strong> -
|
||
<div>
|
||
The SARS-CoV-2 pandemic caused a massive health and societal crisis, although the fast development of effective vaccines reduced some of the impact. To prepare for future pandemics, a pan-viral prophylaxis could be used to control the initial virus outbreak in the period prior to vaccine approval. The liposomal vaccine adjuvant CAF09b contains the TLR3 agonist polyinosinic:polycytidylic acid, which induces a type I interferon (IFN-I) response and an antiviral state in the affected tissues. When testing CAF09b as a potential pan-viral prophylaxis, we observed that intranasal administration of CAF09b to mice resulted in an influx of innate immune cells into the nose and lungs and upregulation of IFN-I related gene expression. When CAF09b was administered prior to challenge with mouse-adapted influenza A/Puerto Rico/8/1934 virus, it protected from severe disease, although virus was still detectable in the lungs. However, when CAF09b was administered after influenza challenge, the mice had a similar disease course to controls. In conclusion, CAF09b may be a suitable candidate as a pan-viral prophylactic treatment for epidemic viruses, but must be administered prior to virus exposure to be effective.

<li><strong>S100A8 and S100A9, biomarkers of SARS-Cov-2-infected patients, suppress HIV replication in primary macrophages</strong> -
|
||
<div>
|
||
S100A8 and S100A9 are members of the Alarmin family; these proteins are abundantly expressed in neutrophils and form a heterodimer complex. Recently, both proteins were identified as novel biomarkers of SARS-CoV-2 infection and were shown to play key roles in inducing an aggressive inflammatory response by mediating the release of large amounts of pro-inflammatory cytokines, called the cytokine storm. Although co-infection with SARS-CoV-2 in people living with HIV-1 may result in an immunocompromised status, the role of the S100A8/A9 complex in HIV-1 replication in primary T cells and macrophages is still unclear. Here, we evaluated the roles of the proteins in HIV replication to elucidate their functions. We found that the complex had no impact on virus replication in both cell types; however, the subunits of S100A8 and S100A9 inhibits HIV in macrophages. These findings provide important insights into the regulation of HIV viral loads during SARS-CoV-2 co-infection.

Abstract Background: Health care workers (HCWs) are particularly exposed to COVID-19 and therefore it is paramount to study preventive measures in this population. Aim: To investigate socio-demographic factors and professional practice associated with the risk of COVID-19 among HCWs in health establishments in Normandy, France Methods: A cross-sectional and 3 case-control studies were conducted in order to explore the possible risk factors that lead to SARS-CoV2 transmission within HCWs, based on an online questionnaire. The case-control studies focused on risk factors associated with care of COVID-19 patients, care of non COVID-19 patients and contacts between colleagues. Findings: Among 2,058 respondents, respectively 1,363 (66.2%) and 695 (33.8%) in medical and medico-social establishments, 301 (14.6%) reported having been infected by SARS-CoV2. When caring for COVID-19 patients, HCWs who declared wearing respirators, either for all patient care (ORa 0.39; 95% CI: 0.29-0.51) or only when exposed to aerosol- generating procedures (ORa 0.56; 95% CI: 0.43-0.70), had a lower risk of infection compared with HCWs who declared wearing mainly surgical masks. During care of non COVID-19 patients, wearing mainly a respirator was associated with a higher risk of infection (ORa 1.84; 95% CI: 1.06-3.37). An increased risk was also found for HCWs who changed uniform in workplace changing rooms (ORa 1.93; 95% CI: 1.63-2.29). Conclusion: Correct use of PPE adapted to the situation and risk level is essential in protecting HCWs against infection.

<li><strong>The challenges of developing biosensors for clinical assessment: a review</strong> -
|
||
<div>
|
||
Emerging research in biosensors has attracted much attention worldwide, particularly in re-sponse to the recent pandemic outbreak of coronavirus disease 2019 (COVID-19). Neverthe-less, initiating research in biosensing applied to the diagnostic of diseases is still challenging for researchers, either from the preferences of biosensor platforms, selection of biomarkers, detection strategies, and other aspects (e.g., cutoff values) to fulfill the clinical purpose. There are two sides to the development of a diagnostic tool: the biosensor development side and the clinical side. From the development side, the research engineers seek the typical characteristics of a biosensor: sensitivity, selectivity, linearity, stability, and reproducibility. On the other side are the physicians that expect a diagnostic tool that provides fast acquisition of patient in-formation to obtain an early diagnostic or an efficient patient stratification, which conse-quently allows making assertive and efficient clinical decisions. The development of diagnostic devices always involves assay developer researchers, working as pivots to bridge both sides, which role is to find detection strategies suitable to the clinical needs. First, by understanding the intended use of the technology and its basic principle; second, the preferable type of test: qualitative or quantitative, sample matrix challenges, biomarker(s) threshold (cutoff value), and if the system requires a mono or multiplex assay format. This review highlights the challenges for the development of biosensors for clinical assessment and its broad application in multidisciplinary fields. This review paper highlights the following biosensor technologies: magnetoresistive (MR)-based, transistor- based, quartz crystal microbalance (QCM), and op-tical-based biosensors. Its working mechanisms are discussed with their pros and cons. The article also gives an overview of the most critical parameters that are optimized by developing a diagnostic tool.

Objective: This study assessed changes in household food insecurity throughout the first year of the COVID-19 pandemic in a cohort of Vermonters and examined the socio-demographic characteristics associated with increased odds of experiencing food insecurity during the pandemic. Design: We conducted three online surveys with a cohort of Vermonters between March 2020 and March 2021 to collect longitudinal data on food security, food access, and job disruptions during the COVID-19 pandemic. Food security was measured using the USDA six-item module. We used t-tests and chi-square tests to determine statistically significant differences between groups and multivariate logistic regression models to determine the factors correlated with food insecurity. Participants: 441 adults (18 years and older) Setting: Vermont, United States Results: Food insecurity rates increased significantly during the pandemic and remained above pre-pandemic levels a year after the start of the pandemic. Nearly a third (31.6%) of respondents experienced food insecurity at some point during the first year of the pandemic. Certain demographic groups were at significantly higher odds of experiencing food insecurity during the first year of the COVID-19 pandemic including households with children (OR 5.1, p < 0.01), women (OR 7.3, p < 0.05), BIPOC/Hispanic respondents (OR 10.4, p < 0.05), and households experiencing a job disruption (OR 4.6, p < 0.01). Conclusion: The prevalence of food insecurity increased during the first year of the COVID-19 pandemic and remained higher than pre-pandemic levels a year after the pandemic began. Odds of experiencing food insecurity during the pandemic vary based on socio-demographic factors.

Background Chest radiographs (CXR) are frequently used as a screening tool for patients with suspected COVID-19 infection pending reverse transcriptase polymerase chain reaction (RT-PCR) results, despite recommendations against this. We evaluated radiologist performance for COVID 19 diagnosis on CXR at the time of patient presentation in the Emergency Department (ED). Materials and Methods We extracted RT PCR results, clinical history, and CXRs of all patients from a single institution between March and June 2020. 984 RT PCR positive and 1043 RT-PCR negative radiographs were reviewed by 10 emergency radiologists from 4 academic centers. 100 cases were read by all radiologists and 1927 cases by 2 radiologists. Each radiologist chose the single best label per case: Normal, COVID 19, Other Infectious, Other Noninfectious, Non diagnostic, and Endotracheal Tube. Cases labeled with endotracheal tube or non-diagnostic were excluded. Remaining cases were analyzed for label distribution, clinical history, and inter-reader agreement. Results 1727 radiographs (732 RT PCR positive, 995 RT PCR negative) were included from 1,594 patients (51.2% male, 48.8% female, age 59 +/- 19 years). For 89 cases read by all readers, there was poor agreement for RT PCR positive (Fleiss Score 0.36) and negative (Fleiss Score 0.46) exams. Agreement between two readers on 1,638 cases was 54.2% (373/688) for RT- PCR positive cases and 71.4% (679/950) for negative cases. Agreement was highest for RT PCR negative cases labeled as Normal (50.4%, n= 479). Reader performance did not improve with clinical history or time between CXR and RT-PCR result. Conclusion At the time of presentation to the emergency department, emergency radiologist performance is non- specific for diagnosing COVID 19.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|

Background: Vaccination is our main strategy to control SARS-CoV-2 infection. Given a decrease in the quantitative SARS-CoV-2 spike 1-2 IgG antibody titers three months following the second BNT162b2 dose, healthcare workers got a third booster dose after six months of completing the original scheme. This study aimed to analyze quantitative SARS-CoV-2 spike 1-2 IgG antibody titers and safety of the third dose. Material and methods: A prospective longitudinal cohort study included healthcare workers who received a third booster dose after six months of the complete BNT162b2 regimen. We assessed the quantitative SARS-CoV-2 spike 1-2 IgG antibody titers 21-28 days after the first and second dose, three months after the complete scheme, 1-7 days following the third dose, and 21-28 days after the boost. Results: The cohort comprised 168 non-immunocompromised participants of 41(10) years old, 67% being women. The third dose was associated with increasing the quantitative antibody titers, regardless of previous SARS-CoV-2 history. In negative SARS-CoV-2 history, the median (IQR) antibody titers increased from 379 (645.4) to 2960 (2010), while in positive SARS-CoV-2 history, from 590 (1262) to 3090 (2080). The third dose had less number of total side effects compared to the other two shots. The most common side effect after the third BNT162b2 shot was pain at the injection site (n=82, 84.5%), followed by tiredness (n=45, 46.4%), with a mild severity (n=36, 37.1%). Tiredness, myalgias, arthralgias, fever, and adenopathy were proportionally higher following the third dose than the two-dose regimen (p<0.05). Conclusion: The third dose applied after six months of the original BNT162b2 regimen provided a good humoral immune response by elevating the quantitative SARS-CoV-2 spike 1-2 IgG antibody titers. The booster dose was well tolerated with no severe side effects after the additional BNT162b2 dose.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|

There is currently a critical need to determine the efficacy of SARS-CoV-2 vaccination for immunocompromised patients. In this study, we determined the neutralizing antibody response in 160 cancer patients diagnosed with chronic lymphocytic leukemia (CLL), lung cancer, breast cancer, and various non-Hodgkin9s lymphomas (NHL), after they received two doses of mRNA vaccines. Serum from 46 mRNA vaccinated health care workers (HCWs) served as healthy controls. We discovered that (1) cancer patients exhibited reduced neutralizing antibody titer (NT50) compared to HCWs; (2) CLL and NHL patients exhibited the lowest NT50 levels, with 50-60% of them below the detection limit; (3) mean NT50 levels in patients with CLL and NHL was ~2.6 fold lower than those with solid tumors; and (4) cancer patients who received anti-B cell therapy exhibited significantly reduced NT50 levels. Our results demonstrate an urgent need for novel immunization strategies for cancer patients against SARS-CoV-2, particularly those with hematological cancers and those on anti-B cell therapies.

<div>
|

The admixture between modern humans and Neandertals has resulted in ~2% of the genomes of present-day non-Africans still being composed of Neandertal DNA. Association studies have shown that introgressed DNA still significantly influences skin and hair traits, immunity and behavioral phenotypes in people today. Several of the phenotype-associated archaic variants had links to regulatory effects as well. In general, analyses of allele-specific expression, regulatory sequence composition and cis-eQTL have demonstrated a significant contribution of this introgressed DNA to the transcriptomic landscape in people today. However, little is known about the impact of Neandertal DNA on trans-eQTLs</div></li>
|
||
<li>long-range regulatory effects that have been shown to explain ~20% of expression variation. Here, we used blood eQTL results from >30,000 individuals from eQTLGen Consortium. The cohort size allowed for a robust identification of trans-eQTLs and in addition enabled quantifying the role of transcription factors (TF) in mediating long-range regulatory effects. In our study we used this information to (i) annotate trans-eQTLs that are linked to Neandertal variants and (ii) predict long-range regulatory effects that are induced by Neandertal DNA by screening for the predicted target genes of TFs that are cis-eQTLs linked to Neandertal variants. We show that both trans-eQTL-associated Neandertal variants and those predicted to have long-range regulatory effects affect genes in genomic regions devoid of Neandertal DNA. In addition, both types of variants included candidates for local adaptation and show associations with autoimmune disorders, a severe Covid-19 phenotype, blood cell type composition and anthropometric measures. Our results suggest that the regulatory reach of Neandertal DNA goes beyond the 40% of genomic sequence that it still covers in present-day non-Africans and that via this mechanism Neandertal DNA additionally influences the phenotypic variation in people today.

<li><strong>Central Banking and Inequalities: Old Tropes and New Practices</strong> -
|
||
<div>
|
||
This paper presents a critical analysis of the stance taken on inequality by two central banks since 2015: the Bank of Canada (BoC) and the Federal Reserve (Fed). The analysis is informed by a computer-assisted discourse analysis of how central bankers from the two institutions position themselves when it comes to issues of inequality. We observe that the position on inequality of the two central banks has changed in recent years and continues to do so. We argue that the stance on inequality taken by the BoC and the Fed suffers from a number of both inconsistencies and shortcomings. On the one hand, the BoC and the Fed claim that monetary policy instruments are too blunt to target specific sectors of the economy. On the other hand, with their response to COVID-19, they have demonstrated that such targeting is possible after all.
