<li><strong>Self-Interest Bias in the COVID-19 Pandemic: A Cross-Cultural Comparison between the United States and China</strong> -
|
||
<div>
|
||
In the global crisis of the COVID-19 pandemic, many countries attempt to enforce new social norms to prevent the further spread of the coronavirus. A key to the success of these measures is the individual adherence to norms that are collectively beneficial to contain the spread of the pandemic. However, individuals’ self-interest bias (i.e., the prevalent tendency to license own but not others’ self-serving acts or norm violations) can pose a challenge to the success of such measures. The current research examines COVID-19-related self-interest bias from a cross-cultural perspective. Two studies (N = 1,558) sampled from the United States and China consistently revealed that participants from the United States evaluated their own self-serving acts (exploiting test kits in Study 1; social gathering and sneezing without covering the mouth in public in Study 2) as more acceptable than identical deeds of others, while such self-interest bias did not emerge among Chinese participants. Cultural underpinnings of independent versus interdependent self-construal may influence the extent to which individuals apply self-interest bias to justifications of their own self-serving behaviors during the pandemic.

Abstract: Background: The ongoing coronavirus pandemic caused by SARS-CoV-2/covid-19/novel coronavirus is an acute infectious communicable disease spreading mainly via respiratory, eye, mouth and other possible routes from person to person as well as through contact with infected non living objects. The pandemic has massively increased healthcare systems burden due to high hospitals admission rate, infection rates, morbidity, and mortality. QALY (quality adjusted life years) & DALY (disability adjusted life years) are also important for consideration of impact of this pandemic. The healthcare systems is under constant massive pressure to halt the spread of the novel coronavirus & a huge part of this responsibility is being shouldered by frontline health care workers including doctors, nurses, paramedical workers, ASHAs and Anganwadi services etc. Hence HCWs are inevitably and routinely exposed to the virus hence naturally are at high risk of infection, possible mortality & morbidities. Objectives: The key objective is to find out impact of SARS-CoV-2/Covid-19 Pandemic on Healthcare Workers (HCWs) Mortality & Infections across 36 states & union territories of India. What are the reasons of mortality and morbidity & How to prevent mortality & morbidity of HCWs? Methodology/settings & design (search strategy-Research Methods): Several databases were searched for deaths of HCWs in India between January 2019 and 18th May 2021, including MoHFW website, PUBMED, WHO COVID-19 database, COVID-19 Study Register, and Google scholar. The search terms used were: “healthcare providers /health care workers/nurses- death in India due to COVID-19”, “SARS-CoV-2”, “Coronavirus,” using Google search. Whatever data obtained is tabulated. Results: There is increase in mortality of HCWs in India. The data is not available completely in my search. Beside increased death I have found a lot of controversy and questions raised on the issue of this data. There is lot of discrepancy in data given by Government and other sources. According to the Indian Medical Association, 244 doctors have lost their lives due to Covid in the second wave. Of them, 50 deaths were recorded on Sunday. The highest number of fatalities have been reported from Bihar (69) followed by Uttar Pradesh (34) and Delhi (27) . Conclusion: The government and other agencies should collect and provide the data publicly so that it can be analysed by different sections of researchers to give feedback which will help in making policies helpful to protect HCWs. A large number of medical staffs are infected due to the lack of adequate protection. Currently, the COVID-19 pandemic is growing day by day with lack of essential facilities for treatment. Some experts have warned of a possible third wave of COVID-19. Keywords: Healthcare workers (HCWs), covid-19 infection, safety, pandemic, Mortality, Doctors, Nurses, Death, India

The identification and isolation of highly infectious SARS-CoV-2-infected individuals is an important public health strategy. Rapid antigen detection tests (RADT) are promising candidates for large-scale screenings due to timely results and feasibility for on-site testing. Nonetheless, the diagnostic performance of RADT in detecting infectious individuals is yet to be fully determined. Two combined oro- and nasopharyngeal swabs were collected from individuals at a routine SARS-CoV-2 diagnostic center. Side-by-side evaluations of RT-qPCR and RADT as well as live virus cultures of positive samples were performed to determine the sensitivity of the Standard Q COVID-19 Ag Test (SD Biosensor/Roche) in detecting SARS-CoV-2-infected individuals with cultivable virus. A total of 2,028 samples were tested and 118 virus cultures inoculated. SARS-CoV-2 infection was detected in 210 samples by RT-qPCR, representing a positive rate of 10.36%. The Standard Q COVID-19 Ag Test yielded a positive result in 92 (4.54%) samples resulting in an overall sensitivity and specificity of 42.86% and 99.89%. For adjusted Ct values <20, <25, and <30 the RADT reached sensitivities of 100%, 98.15%, and 88.64%, respectively. All 29 culture positive samples were detected by RADT. While overall sensitivity was low, Standard Q COVID-19 RADT reliably detected patients with high RNA loads. Additionally, negative RADT results fully corresponded with the lack of viral cultivability in Vero E6 cells. These results indicate that RADT can be a valuable tool for the detection of individuals that are likely to transmit SARS-CoV-2. RADT testing could therefore guide public health testing strategies to combat the COVID-19 pandemic.

Emerging evidence suggests that contact tracing has had limited success in the UK in reducing the R number across the COVID-19 pandemic. We investigate potential pitfalls and areas for improvement by extending an existing branching process contact tracing model, adding diagnostic testing and refining parameter estimates. Our results demonstrate that reporting and adherence are the most important predictors of programme impact but tracing coverage and speed plus diagnostic sensitivity also play an important role. We conclude that well-implemented contact tracing could bring small but potentially important benefits to controlling and preventing outbreaks, providing up to a 15% reduction in R, and reaffirm that contact tracing is not currently appropriate as the sole control measure.

The emergence of the Covid-19 pandemic caused Indonesia’s economy to experience deflation, the group whose income is not affected prefer to save rather than spending their money, this happen with consideration that no one knows when the Covid-19 pandemic will end and when will the the situation return to normal. The pandemic has decreased people’s income and purchasing power. People saving are decreased used for consumption needs, especially for the employee that’s terminated from the the company or has been laid off, this cases resulting in and increasingly depleted source of household funds.

Micro, Small, and Medium Enterprises (MSMEs) have a very vital role in the development and economic growth in Indonesia. According to the Ministry of Cooperatives and SMEs, in 2020, MSMEs have a total of 60% contribution to the Gross Domestic Bruto and 90% contribution to the national workforce absorption. Therefore, the recovery of MSMEs is very important for the well-being of the national economy. The Covid-19 pandemic must encourage MSMEs actors to transform their businesses if they want to survive. Business digitalization during the Covid-19 pandemic is growing faster. Therefore, the recovery of MSMEs cannot be separated from the utilization of information technology.

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

Background: SARS-CoV-2 infection during pregnancy is associated with significant maternal morbidity and increased rates of preterm birth. For this reason, COVID-19 vaccine administration in pregnancy has been endorsed by multiple professional societies including ACOG and SMFM despite exclusion of pregnant women from initial clinical trials of vaccine safety and efficacy. However, to date little data exists regarding outcomes after COVID-19 vaccination of pregnant patients. Study Design: A comprehensive vaccine registry was combined with a delivery database for an integrated healthcare system to create a delivery cohort including vaccinated patients. Maternal sociodemographic data were examined univariately for factors associated with COVID-19 vaccination. Pregnancy and birth outcomes were analyzed, including a composite measure of maternal and neonatal pregnancy complications, the Adverse Outcome Index. Results: Of 2002 patients in the delivery cohort, 140 (7.0%) received a COVID-19 vaccination during pregnancy and 212 (10.6%) experienced a COVID-19 infection during pregnancy. The median gestational age at first vaccination was 32 weeks (range 13 6/7-40 4/7), and patients vaccinated during pregnancy were less likely than unvaccinated patients to experience COVID-19 infection prior to delivery (1.4% (2/140) vs. 11.3% (210/1862)) P<0.001No maternal COVID-19 infections occurred after vaccination during pregnancy. Factors significantly associated with increased likelihood of vaccination included older age, higher level of maternal education, lower pre-pregnancy BMI, and use of infertility treatment for the current pregnancy. Tobacco or other substance use, Hispanic ethnicity, and higher gravidity were associated with a lower likelihood of vaccination. No significant difference in the composite adverse outcome (5.0% (7/140) vs. 4.9% (91/1862) P=0.95) or other maternal or neonatal complications, including thromboembolic events and preterm birth, was observed in vaccinated mothers compared to unvaccinated patients. Conclusions: Vaccinated pregnant women in this birth cohort were less likely to experience COVID-19 infection compared to unvaccinated pregnant patients, and COVID-19 vaccination during pregnancy was not associated with increased pregnancy or delivery complications. Significant sociodemographic disparities in vaccine uptake and/or access were observed among pregnant patients, and future efforts should focus on outreach to low-uptake populations.

In the current SARS-CoV-2 pandemic, testing for SARS-CoV-2 specific antibodies is paramount to monitor immune responses in post-authorization vaccination and sero-epidemiology studies. However, large scale and iterative serological testing by venipuncture in older persons can be challenging. Capillary blood sampled using a finger prick and collected on protein saver cards, i.e. dried blood spots (DBS), has already proven to be a promising alternative. However, elderly persons have a reduced cutaneous microvasculature, which may affect DBS-based antibody testing. Therefore, we aimed to evaluate the performance of DBS for the detection of SARS-CoV-2 antibodies in nursing homes residents. We collected venous blood and paired Whatman and EUROIMMUN DBS from nursing home residents, and from staff as a reference population. Venous blood samples were analyzed for the presence of SARS-CoV-2 IgG antibodies using the Abbot chemiluminescent microparticle immunoassay (CMIA). DBS were analyzed by the EUROIMMUN enzyme-linked immuno sorbent assay (ELISA) for SARS-CoV-2 IgG antibodies. We performed a statistical assessment to optimize the ELISA cut-off value for the DBS using the Youden9s J index. A total of 273 paired DBS-serum samples were analyzed, of which 129 were positive as assessed by the reference test. The sensitivities and specificities of DBS ranged from 95% to 97.1% and from 97.1% to 98.8%, respectively, depending on population (residents or staff) or DBS card type. These results demonstrate that DBS sampling is a valid alternative to venepuncture for the detection of SARS-CoV-2 antibodies in the elderly.

Several studies have shown that subjects with a history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection had significantly higher antibody titers than previously uninfected vaccinees after vaccination with mRNA vaccine. Yet no information is available for other vaccines. In the current observational cohort study, 105 health care workers who had received Covishield an Adeno associated viral vector-based DNA vaccine were enrolled at Sarojini Nadu Medical College Agra, India. The study included 40 (23 men and 17 women) subjects with a previous history of SARS-CoV-2 infection and 65 participants (39 men and 26 women) who were not infected previously. Both the groups received the adenovirus vector vaccine ChAdOx1-S recombinant vaccines (Covishield, Astra Zeneca). The levels of SARS-CoV-2-anti-spike-IgG-antibodies titer were measured using Electrochemiluminescence immunoassay on Roche platform as arbitrary units per milliliter (AU/ml). After 28 days of the second dose, subjects with no previous SARSCoV-2 infection showed a significantly lower level of circulating anti-spike-IgG-antibody titers compared to previously infected participants. After the second dose, we also observed a significant increase in SARS-CoV-2 infection in subjects with no prior history of SARS-CoV-2 infection compared to subjects with a previous history of natural infection. The most important observation of the study is a low percentage of infection in previously infected subjects. The finding of the study also indicates the presence of robust humoral memory response in previously infected patients.

Understanding the evolution of SARS-CoV-2 virus in various regions of the world during the Covid19 pandemic is of the utmost importance to help mitigate the effects of this devastating disease. We describe the phylogenomic and population genetic patterns of the virus in Mexico during the pre-vaccination stage, including asymptomatic carriers. Our RT-qPCR screening and phylogenomics directed a sequence/structure analysis of the Spike glycoprotein, revealing mutation of concern E484K in genomes from central Mexico, in addition to the nationwide prevalence of the imported variant 20C/S:452R (B.1.427/9). Overall, the detected variants in Mexico show mutations in the N-terminal domain (i.e., R190M), in the receptor-binding motif (i.e., T478K, E484K), within the S1-S2 subdomains (i.e., P681R/H, T732A), and at the basis of the protein, V1176F, raising concerns about the lack of phenotypic and clinical data available for the postulated variants of interest (VOIs) 20B/478K.V1 and P.3. Moreover, the population patterns of Single Nucleotide Variants (SNVs) from symptomatic and asymptomatic carriers sampled with a self-sampling scheme, revealed a bimodal distribution of polymorphisms in all three sampled localities from central Mexico, and confirmed the presence of several fixed variants, mostly from the 241T-3037T-14408T-23403G haplotype common in Asia. Despite gene flow among Mexican localities, we found differences in both the allelic frequencies among localities and the allelic imbalance of the mutation S194L of the nucleocapsid protein between symptomatic and asymptomatic carriers. Our results highlight the dual role of Spike and Nucleocapsid proteins in adaptive evolution of SARS-CoV-2 to their hosts and provide a baseline for specific follow-up of mutations of concern during the vaccination stage in Mexico.

Since first patient detected in India in late February, 2020, SARS-CoV-II virus is playing havoc on India. After the first wave, India is now riding the 2nd wave. As was in the case of European countries like Italy and UK, the 2nd wave is more contagious and at the time of writing this paper, the per day infection is as high as 400,000. The alarming thing is it is not uncommon that people is getting infected multiple time. On the other hand, mass vaccination has started step by step. There is also growing danger of potential 3rd wave is unavoidable, which can even infect kids and minors. In this situation, an estimation of the dynamics of SARS-CoV-2 is absolutely necessary to combat the pandemic. We have used a modified SEIRD model, that includes vaccination and repeat infection as well. We have studied India and 8 Indian states with varying SARS-CoV-2 infection. We have shown that, Covid-19 wave will be repeated time to time, but the intensity will slow down with time. In most possible situation, our calculation shows COVID-19 will remain as endemic for foreseeable future, unless we are able to increase our vaccination rate manifold.

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

Background Engineering controls are a necessity for minimising aerosol transmission of SARS-CoV-2, yet so far, little attention has been given to such interventions. High flow local extraction (HFLE) is a standard in other industries that deal with airborne contaminants. This study provides a quantitative evaluation of an HFLE concept feasible to implement in most real clinical settings. Method A unique combined experimental model of Laser sheet illumination videography paired with continuous nanoparticle counts was used to quantitatively assess the impact of HFLE in an operating theatre. Propylene Glycol was aerosolised via a customised physiological lung simulator and dispersion was measured in 3 dimensions. Cumulative probability heat maps were generated to describe aerosol behaviour. Continuous particle counts were made at 15 locations throughout the room to validate laser assessments. Results HFLE effectively reduced dispersion of simulated exhaled aerosols to undetectable levels. With the HFLE in operation and optimally positioned, the aerosol plume was tightly controlled. Particle counts remained at baseline when HFLE was active. HFLE becomes less effective with increasing distance from source. Plume behaviour in the absence of HFLE was highly variable and unpredictable. Conclusions This analysis demonstrates great potential for HFLE to have a significant impact in reducing aerosol transmission. Simple HFLE devices can be easily engineered and could be widely deployed without impacting on the safe delivery of care.

The positive impact of meditation on human wellbeing is well documented, yet its molecular mechanisms are incompletely understood. We applied a comprehensive systems biology approach starting with whole blood gene expression profiling combined with multi-level bioinformatic analyses to characterize the co-expression, transcriptional, and protein-protein interaction networks to identify meditation-specific core network after an advanced 8-day Inner Engineering retreat program. We found the response to oxidative stress, detoxification, and cell cycle regulation pathways were downregulated after meditation. Strikingly, 220 genes directly associated with immune response, including 68 genes related to interferon (IFN) signaling were upregulated, with no significant expression changes in the inflammatory genes. This robust meditation-specific immune response network is significantly dysregulated in multiple sclerosis and severe COVID-19 patients. The work provides a foundation for understanding the effect of meditation and potential implications to voluntarily and non-pharmacologically improve the immune response before immunotherapy for many conditions, including multiple sclerosis and COVID-19 vaccination.

<li><strong>Implications Derived from S-Protein Variants of SARS-CoV-2 from Six Continents</strong> -
|
||
<div>
|

Spike (S) proteins of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are critical determinants of the infectivity and antigenicity of the virus. Several mutations in the spike protein of SARS-CoV-2 have already been detected, and their effect in immune system evasion and enhanced transmission as a cause of increased morbidity and mortality are being investigated. From pathogenic and epidemiological perspectives, spike proteins are of prime interest to researchers. This study focused on the unique variants of S proteins from six continents Asia, Africa, Europe, Oceania, South America, and North America. In comparison to the other five continents, Africa (29.065%) had the highest percentage of unique S proteins. Notably, only North America had 87% (14046) of the total (16143) specific S proteins available in the NCBI database (across all continents). Based on the amino acid frequency distributions in the S protein variants from all the continents, the phylogenetic relationship implies that unique S proteins from North America were significantly different from those of the other five continents. Overtime, the unique variants originating from North America are most likely to spread to the other geographic locations through international travel or naturally by emerging mutations. Hence it is suggested that restriction of international travel should be considered, and massive vaccination as an utmost measure to combat the spread of COVID-19 pandemic. It is also further suggested that the efficacy of existing vaccines and future vaccine development must be reviewed with careful scrutiny, and if needed, further re-engineered based on requirements dictated by new emerging S protein variants.

Rapid deployment of non-invasive therapeutic avenues capable of preventing infection by all SARS-CoV-2 variants could complement current vaccination efforts and help turn the tide on the COVID-19 pandemic. Here, we describe a novel therapeutic strategy targeting the SARS-CoV-2 RNA using locked nucleic acid antisense oligonucleotides (LNA ASOs). We identified an LNA ASO binding to the 5’ leader sequence of SARS-CoV-2 ORF1a/b that disrupts a highly conserved stem-loop structure with nanomolar efficacy in preventing viral replication in human cells. Daily intranasal administration of this LNA ASO in the K18-hACE2 humanized COVID-19 mouse model potently (98-99%) suppressed viral replication in the lungs of infected mice, revealing strong prophylactic and treatment effects. We found that the LNA ASO also represses viral infection in golden Syrian hamsters, and is highly efficacious in countering all SARS-CoV-2 “variants of concern” tested in vitro and in vivo, including B.1.427, B.1.1.7, and B.1.351 variants. Hence, inhaled LNA ASOs targeting SARS-CoV-2 represents a promising therapeutic approach to reduce transmission of variants partially resistant to vaccines and monoclonal antibodies, and could be deployed intranasally for prophylaxis or via lung delivery by nebulizer to decrease severity of COVID-19 in infected individuals. LNA ASOs are chemically stable and can be flexibly modified to target different viral RNA sequences, and they may have particular impact in areas where vaccine distribution is a challenge, and could be stockpiled for future coronavirus pandemics.

To prevent the spread of virus, it is important to disinfect commonly touched objects. One of the ways suggested is to use a personal UV-C disinfecting box that is “efficient and effective in deactivating the COVID-19 virus. The present model has implemented the use of a UV transparent material (fused silica quartz glass tubes) as the medium of support for the objects to be disinfected to increase the effectiveness of disinfection without compromising the load bearing capacity. Aluminum foil, a UV reflecting material, was used as the inner lining of the box for effective utilization of the UVC light emitted by the UVC lamps. Care has been taken to prevent leakage of UVC radiation out of the system.
