Vaccination against COVID-19 is making progress globally, but vaccine doses remain a rare commodity in many parts of the world. Policymakers have defined criteria to regulate who gets priority access to the vaccination, such as age, health complications, or those who hold system-relevant jobs. We explore public preferences about vaccine allocation using a survey that was fielded in five countries from September to December 2020 (Brazil, Germany, Italy, Poland, and the United States). We measure preferences using ranking and forced-choice tasks. We find that the public agrees with expert guidelines in giving priority to healthcare workers and people with medical preconditions. However, they also consider those signing up early for vaccination and citizens of the country to be more deserving of priority access to vaccination than later-comers and non-citizens. These results hold across measures, countries, and sociodemographic subgroups.

To address the global Covid-19 pandemic, governments around the world require on the collective cooperation of their citizens to comply with public health regulation. Earlier studies examined the extent to which self-construal has an impact on individual compliance to law. However, existing literature has paid little significant attention to behavioural outcome of self-construal in the pandemic context across countries and cultures.

<li>to determine whether interdependent self-construal predicts compliance of Covid-19 public health regulation, 2) to examine if the association was mediated by individual social trust, and 3) to test whether these associations were moderated by respondent’s country of residence (US x Indonesia). General adult respondents from US (N=231) and Indonesia (N=440) were voluntary participated in a survey measuring their trust to the government, interdependent self-construal orientation and compliance toward Covid-19 public health regulation. While our moderated mediation model involving respondent’s country residence did not support the hypothesis, the mediation analysis demonstrated significant association between interdependent self-construal and compliance via social trust. Our additional simple moderation analysis on direct effect of interdependent self-construal and compliance showed significant findings. Further, theoretical and practical implications of these findings were discussed in the following paper.

<li><strong>‘Feeling Fat’ Amid the COVID-19 Pandemic: Examining the Role of Emotion Dysregulation in the Body Displacement Hypothesis</strong> -
|
|||
|
|
<div>
|
|||
|
|
‘Feeling fat,’ the somatic experience of being overweight not entirely explained by objective weight, may occur due to the projection of negative affect onto the body. Individuals may manage ‘feeling fat’ via eating pathology (e.g., binge eating or dietary restriction) rather than address the source of negative affect. Thus, ‘feeling fat’ may occur in the absence of adaptive emotion regulation strategies. The COVID-19 pandemic has increased negative affect widely and may potentially contribute to the experience of ‘feeling fat’ and eating pathology among individuals with emotion dysregulation. This study examined whether emotion dysregulation moderates ‘feeling fat’s role as a mechanism underlying the relationship between COVID-19-related distress and eating pathology. This uniqueness of this model to eating pathology was investigated by comparing effects for binge eating and dietary restriction versus anxiety, depression, and problematic alcohol use. Structural equation modelling was used to analyze questionnaire data from 877 participants (77.3% women). ‘Feeling fat’ explained significant variance in the relationship between COVID-19-related distress and both binge eating and restriction. Emotion dysregulation moderated the strength of these relationships. However, ‘feeling fat’s role in the relationship between pandemic-related distress and negative psychological outcomes was not unique to eating pathology and did not vary based upon emotion dysregulation. Individuals with elevated emotion dysregulation are more likely to report eating pathology, but not other outcomes, when experiencing increased ‘feeling fat’. In contrast, ‘feeling fat’ underlies the relationship between COVID-19-related distress and transdiagnostic psychological outcomes, meaning ‘feeling fat’ should be considered a risk for psychopathology beyond eating disorders.

<li><strong>Risk perception and behaviour change after personal vaccination for COVID-19 in the USA</strong> -

Although vaccines are crucial for giving pandemic-stricken societies the confidence to return to socioeconomic normalcy, vaccination may also induce laxity in personal protective behaviours (e.g., handwashing, facemask use). We use the quasi-experimental context of the COVID-19 vaccine rollout across the United States to quantify the impact of different stages of personal vaccination on people’s risk perceptions, daily activities, and risk mitigation behaviours, which we measure in a three-wave national panel study (N wave-1 = 7,358, N wave-2 = 3,000, N wave-3 = 2,345) from March to June, 2021, and validate using vaccination, infection, and human mobility data. Socializing rebounded after only partial vaccination. After full vaccination, communal activities recovered; however, the propensity for protective behaviours declined. The effects were heterogenous depending on vaccination level, demographics, and infection history. We further use a utility theory framework to model risk-value trade-offs and risk-construction for different behaviours.

Multiple COVID-19 vaccines, representing diverse vaccine platforms, successfully protect against symptomatic COVID-19 cases and deaths. Head-to-head comparisons of T cell, B cell, and antibody responses to diverse vaccines in humans are likely to be informative for understanding protective immunity against COVID-19, with particular interest in immune memory. Here, SARS-CoV-2-spike-specific immune responses to Moderna mRNA-1273, Pfizer/BioNTech BNT162b2, Janssen Ad26.COV2.S and Novavax NVX-CoV2373 were examined longitudinally for 6 months. 100% of individuals made memory CD4+ T cells, with cTfh and CD4-CTL highly represented after mRNA or NVX-CoV2373 vaccination. mRNA vaccines and Ad26.COV2.S induced comparable CD8+ T cell frequencies, though memory CD8+ T cells were only detectable in 60-67% of subjects at 6 months. Ad26.COV2.S was not the strongest immunogen by any measurement, though the Ad26.COV2.S T cell, B cell, and antibody responses were relatively stable over 6 months. A differentiating feature of Ad26.COV2.S immunization was a high frequency of CXCR3+ memory B cells. mRNA vaccinees had substantial declines in neutralizing antibodies, while memory T cells and B cells were comparatively stable over 6 months. These results of these detailed immunological evaluations may also be relevant for vaccine design insights against other pathogens.

Recombination between SARS-CoV-2 virus variants can result in different viral properties (e.g., infectiousness or pathogenicity). In this report, we describe viruses with recombinant genomes containing signature mutations from Delta and Omicron variants. These genomes are the first evidence for a Delta-Omicron hybrid Spike protein in the United States.

Unlike most other viral pneumonitis, SARS-CoV-2 often causes hyperferritinemia, elevations in D-dimer, lactate dehydrogenase (LDH), transaminases, troponin, CRP, and other inflammatory markers. We questioned (1) if the severity of pneumonitis observed on lung ultrasound was associated with hospitalization and (2) could lung ultrasound be used to stratify which children needed blood tests? Methods We did a retrospective cross-sectional review of children aged between 14 days and 21 years of age being evaluated for Covid-19 in our pediatric emergency department from 30/November/2019 to 14/August/2021 who had had a point-of-care lung ultrasound. Lung ultrasounds were categorized using a 6-point ordinal scale. We used logistic regression to estimate the adjusted effect of lung ultrasound on hospital admission. We performed ordinary least square regression for the association between lung ultrasound severity and laboratory abnormalities. We adjusted these using propensity score derived inverse probability weighting to account for the non-random decision to obtain laboratory investigations. Results We identified 500 point-of-care lung ultrasounds of which 427 could be assigned a severity category. Increasing lung ultrasound severity was associated with increased hospital admission OR 1.36( 95% CI 1.08, 1.72.) Ferritin, LDH, transaminases, and D-dimer, but not CRP or troponin were significantly associated with more than moderately severe lung ultrasounds. D-Dimer, CRP, and troponin were sometimes elevated even when lung ultrasound was normal. Conclusion Severity of pneumonitis was associated with hospital admission. Ferritin, LDH, transaminases, and D-dimer were increased in more than moderately severe pneumonitis but lung ultrasound did not predict elevation of other markers.

Community testing is a crucial tool for the early identification of SARS-CoV-2 infection and transmission control. The emergence of the highly mutated Omicron variant (B.1.1.259) raised concerns about its primary site of replication, impacting sample collection, and its detectability by rapid antigens tests. We tested the Antigen Rapid Diagnostic Test (Ag-RDT) performance using nasal, oral, and saliva specimens for COVID-19 diagnosis in 192 symptomatic individuals, using RT-qPCR from nasopharyngeal samples as control. Variant of Concern (VOC) investigation was determined by the 4Plex SARS-CoV-2 screening kit. SARS-CoV-2 positivity rate was 66.2%, with 99% of the positive samples showing an amplification profile consistent with that of the Omicron variant. Nasal Ag-RDT showed higher sensitivity (89%) than oral (12.6%) and saliva (22.1%) Ag-RDTs. Our data showed the good performance of the Ag-RDT in a pandemic scenario dominated by the Omicron VOC. Furthermore, our data also demonstrated that nasal specimens perform better than oral and saliva ones for Omicron Ag-RDT detection.

By 31st December 2021, Seychelles, an archipelago of 115 islands in the Indian Ocean, had confirmed 24,788 cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first SARS-CoV-2 cases in Seychelles were reported on 14th March 2020, but cases remained low until January 2021, when a surge of SARS-CoV-2 cases was observed on the islands. Here, we investigated the potential drivers of the surge by genomic analysis 1,056 SARS-CoV-2 positive samples collected in Seychelles between 14th March 2020 and 31st December 2021. The Seychelles genomes were classified into 32 Pango lineages, 1,042 of which fell within four variants of concern i.e., Alpha, Beta, Delta and Omicron. Sporadic of SARS-CoV-2 detected in Seychelles in 2020 were mainly of lineage B.1 (Europe origin) but this lineage was rapidly replaced by Beta variant starting January 2021, and which was also subsequently replaced by the Delta variant in May 2021 that dominated till November 2021 when Omicron cases were identified. Using ancestral state reconstruction approach, we estimated at least 78 independent SARS-CoV-2 introduction events into Seychelles during the study period. Majority of viral introductions into Seychelles occurred in 2021, despite substantial COVID-19 restrictions in place during this period. We conclude that the surge of SARS-CoV-2 cases in Seychelles in January 2021 was primarily due to introduction of the more transmissible SARS-CoV-2 variants into the islands.

Background: Acute kidney injury (AKI) is one of the most common and significant problems in patients with COVID-19. However, little is known about the incidence and impact of AKI occurring in the community or early in the hospital admission. The traditional KDIGO definition can fail to identify patients for whom hospitalization coincides with recovery of AKI as manifested by a decrease in serum creatinine (sCr). We hypothesized that an extended KDIGO definition, adapted from the International Society of Nephrology 0by25 studies, would identify more cases of AKI in patients with COVID-19 and that these may correspond to community-acquired AKI with similarly poor outcomes as previously reported in this population. Methods and Findings: All individuals in the ISARIC cohort admitted to hospital with SARS-CoV-2 infection from February 15th, 2020, to February 1st, 2021, were included in the study. Data was collected and analysed for the duration of a patient’s admission. Incidence, staging and timing of AKI were evaluated using a traditional and extended KDIGO (eKDIGO) definition which incorporated a commensurate decrease in serum creatinine. Patients within eKDIGO diagnosed with AKI by a decrease in sCr were labelled as deKDIGO. Clinical characteristic and outcomes – intensive care unit (ICU) admission, invasive mechanical ventilation and in-hospital death</p></div></li>
|
|||
|
|
<li>were compared for all three groups of patients. The relationship between eKDIGO AKI and in-hospital death was assessed using survival curves and logistic regression, adjusting for disease severity and AKI susceptibility. 75,670 patients from 54 countries were included in the final analysis cohort. Median length of admission was 12 days (IQR 7, 20). There were twice as many patients with AKI identified by eKDIGO than KDIGO (31.7 vs 16.8%). Those in the eKDIGO group had a greater proportion of stage 1 AKI (58% vs 36% in KDIGO patients). Peak AKI occurred early in the admission more frequently among eKDIGO than KDIGO patients. Compared to those without AKI, patients in the eKDIGO group had worse renal function on admission, more in-hospital complications, higher rates of ICU admission (54% vs 23%) invasive ventilation (45% vs 15%) and increased mortality (38% vs 19%). Patients in the eKDIGO group had a higher risk of in- hospital death than those without AKI (adjusted OR: 1.78, 95% confidence interval: 1.71-1.8, p-value < 0.001). Mortality and rate of ICU admission were lower among deKDIGO than KDIGO patients (25% vs 50% death and 35% vs 70% ICU admission) but significantly higher when compared to patients with no AKI (25% vs 19% death and 35% vs 23% ICU admission) (all p values < 5x10-5). Limitations include ad hoc sCr sampling, exclusion of patients with less than two sCr measurements, and limited availability of sCr measurements prior to initiation of acute dialysis. Conclusions: The use of an extended KDIGO definition to diagnose AKI in this population resulted in a significantly higher incidence rate compared to traditional KDIGO criteria. These additional cases of AKI appear to be occurring in the community or early in the hospital admission and are associated with worse outcomes than those without AKI.

Background. The COVID-19 pandemic is an ongoing global crisis, with a multitude of factors that affect mental health worldwide. Here, we explore potential predictors for the emergence and maintenance of depression, anxiety, and posttraumatic stress symptoms (PTSS) in the general population in Israel. Methods. Across the span of 16 months, 2,478 people completed a repeated self-report survey which inquired psychiatric symptoms and pandemic related stress factors (PRSF). PRSF were divided into four clusters of environmental stressors: financial, health-related, fatigue and sense of protection by authorities. We applied mixed-effects linear models to assess how each stressor contributes to depression, anxiety and PTSS at each time point, alongside a longitudinal exploration among participants who completed at least two consecutive surveys (n=400). Results. Fatigue was the strongest predictor for depression, anxiety and PTSS at all time points (standardized β between 0.28-0.60, p<.0001), and predicted deterioration overtime (β between 0.22-0.36, p<.0001). Financial concerns associated with depression and anxiety at all time points (β between 0.13-0.26, p<.01), and with their deterioration overtime (β between 0.16-0.18, p<.0001), while health related concerns were uniquely associated with anxiety and PTSS at all time points (β between 0.14-0.29, p<.01) and their deterioration (β between 0.11-0.16, p<.001), but not with depression. Improvement in sense of protection overtime associated with decrease in depression and anxiety (β between -0.09 to -0.16, p<.01). Conclusions. Our findings accentuate the multitude of risk factors for psychiatric morbidity during COVID-19, and the dynamics in their association with different aspects of psychopathology at various time points.

Objective: Cancer is comorbidity, which can lead to progressive worsening of Covid-19 with increased mortality. This is a systematic review and meta-analysis to get evidence of adverse outcomes of Covid-19 in gynecologic cancer. Methods: Searches through PubMed, Google Scholar, ScienceDirect, and medRxiv to find articles on the outcome of gynecologic cancer with Covid-19 (24 July 2021-19 February 2022). Newcastle-Ottawa Scale tool used to evaluate the quality of included studies. Pooled odds ratio (OR), 95% confidence interval (CI), random-effects model were presented. This study registered to PROSPERO (CRD42021256557). Results: We accepted 49 studies with (1994 gynecologic cancer with Covid-19). Covid-19 infection was lower in gynecologic cancer vs hematologic cancer (OR 0.71, CI 0.56-0.89, p 0.003). Severe Covid and death were lower in gynecologic cancer vs lung and hematologic cancer (OR 0.36, CI 0.16-0.80, p 0.01), (OR 0.26, CI 0.10-0.67 p 0.005), (OR 0.52, CI 0.43-0.63, p <0.0001), (OR 0.65, CI 0.49-0.87, p 0.003) respectively. Increased Covid death is seen in gynecologic cancer vs breast, non-covid cancer, and non cancer covid (OR 1.51, CI 1.20-1.90, p 0.0004), (OR 12.21, CI 8.39- 17.77, p <0.0001), (OR 3.06, CI 2.32-4.04, p <0.0001) respectively. Conclusion: Gynecologic cancer had increased Covid-19 adverse outcomes compared to non-cancer, breast cancer, non- metastatic, and Covid-19 negative population. Gynecologic cancer had lowered Covid-19 adverse outcomes compared to other cancer types, lung cancer, and hematologic cancer. Lack of age and comorbidities stratification due to limited data were limitations. These findings may aid health policies and services during the ongoing global pandemic.

RNA interference is a natural antiviral mechanism that could be harnessed to combat SARS-CoV-2 infection by targeting and destroying the viral genome. We screened lipophilic small-interfering RNA (siRNA) conjugates targeting highly conserved regions of the SARS-CoV-2 genome and identified leads targeting outside of the spike-encoding region capable of achieving [≥]3-log viral reduction. Serial passaging studies demonstrated that a two-siRNA combination prevented development of resistance compared to a single-siRNA approach. A two-siRNA combination delivered intranasally protected Syrian hamsters from weight loss and lung pathology by viral infection upon prophylactic administration but not following onset of infection. Together, the data support potential utility of RNAi as a prophylactic approach to limit SARS-CoV-2 infection that may help combat emergent variants, complement existing interventions, or protect populations where vaccines are less effective. Most importantly, this strategy has implications for developing medicines that may be valuable in protecting against future coronavirus pandemics.

<li><strong>Stability and expression of SARS-CoV-2 spike-protein mutations</strong> -

Protein fold stability likely plays a role in SARS-CoV-2 S-protein evolution, together with ACE2 binding and antibody evasion. While few thermodynamic stability data are available for S-protein mutants, many systematic experimental data exist for their expression. In this paper, we explore whether such expression levels relate to the thermodynamic stability of the mutants. We studied mutation-induced SARS-CoV-2 S-protein fold stability, as computed by three very distinct methods and eight different protein structures to account for method- and structure-dependencies. For all methods and structures used (24 comparisons), computed stability changes correlate significantly (99% confidence level) with experimental yeast expression from the literature, such that higher expression is associated with relatively higher fold stability. Also significant, albeit weaker, correlations were seen for ACE2 binding. The effect of thermodynamic fold stability may be direct or a correlate of amino acid or site properties, notably the solvent exposure of the site. Correlation between computed stability and experimental expression and ACE2 binding suggests that functional properties of the SARS-CoV-2 S-protein mutant space are largely determined by a few simple features, due to underlying correlations. Our study lends promise to the development of computational tools that may ideally aid in understanding and predicting SARS-CoV-2 S-protein evolution.

Over 15-months we found that anti-spike RBD SARS-CoV-2 antibody concentrations follow different trends with combinations and permutations of COVID-19 infection and vaccination among healthcare workers in Boston, MA. A majority of HCWs remain well above the positivity threshold for anti-spike RBD IgG antibodies for at least 9 months following vaccination regardless of infection history. Of interest, those with COVID-19 infection before vaccination had significantly higher median serum antibody concentrations in comparison to HCWs with no prior infection at each follow- up timepoint. These findings further support what is known regarding the decline in serum antibody concentrations following natural infection and vaccination, adding knowledge of serum antibodies up to 15 months post infection and 11 months post vaccination.

Initially, the system receives a student profile. Further, the system receives a question from the student. Furthermore, the system synthesizes the question based on a set of predefined machine learning model. Subsequently, the system determines a cohort of the students from the set of the cohort of the students. The cohort of the students is determined based on the one or more parameters related to the question. Further, the system identifies a tutor assigned to the cohort of the students. Subsequently, the system notifies the tutor in real time. Further, the system receives an acknowledgement from the tutor within a predefined time. Finally, the system connects the tutor with the student in real time when the acknowledgement is the positive acknowledgement. - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN352550208">link</a></p></li>

Since the COVID has stopped the Industries/Companies to conduct campus interview and direct recruitment throughout India. This leads to huge unemployment and companies lack in finding the correct person for their job. To overcome this issue it is proposed to develop an application where recruiters can easily conduct their recruitment process. This app integrates the student’s database and the Industry/company database. This model helps the recruiter to choose the eligible student from the huge database instead of a group of students from a particular University/college. There are many benefits like faster recruitment process, many students finding their dream job, HR process the interview from the remote location, entire process is in online, no need to travel and accommodate a place for rent. The entire process is recorded and saved as a report, this ensures 100 % genuine and no space for malpractice. - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN352549250">link</a></p></li>

One way to address this problem is to explore the use of robots that can support clinical teams, e.g., to deliver materials or restock supplies. However, due to EDs being overcrowded, and the cognitive overload HCWs experience, robots need to understand various levels of patient acuity so they avoid disrupting care delivery. In this invention, we introduce the Safety-Critical Deep Q-Network (SafeDQN) system, a new acuity-aware navigation system for mobile robots. SafeDQN is based on two insights about care in EDs: high-acuity patients tend to have more HCWs in attendance and those HCWs tend to move more quickly. We compared SafeDQN to three classic navigation methods, and show that it generates the safest, quickest path for mobile robots when navigating in a simulated ED environment. We hope this work encourages future exploration of social robots that work in safety-critical, human-centered environments, and ultimately help to improve patient outcomes and save lives.
