<li><strong>Improving Lab Culture Through Self-Assessment: A Case Study</strong> -
|
||
<div>
|
||
Purpose: Motivated by perceived dissatisfaction within our labs changed working environment brought about by the COVID-19 pandemic, we performed a self-assessment of our lab culture through anonymous surveys and live sessions. Methods: In Survey 1, we asked each lab member to identify and rank up to 10 values that are important for a healthy lab environment. They were then asked to rate how well the lab embodied those values at two time points: before the COVID-19 pandemic while working onsite, and at the time of the survey while working remotely (10 months into the pandemic). In a series of live group sessions, we reviewed relevant literature and the survey results to finalize ten themes. We then reflected on each theme and proposed action items to address any deficiencies. Finally, we conducted Survey 2 after the self-assessment to judge the group’s finalized themes, implemented changes, and overall satisfaction with the assessment process. Results: Themes identified were attitude, accountability, teamwork/collaboration, communication, diversity/inclusion, emotional intelligence, integrity, training, well-being, and adaptability in crisis- management. All lab members liked the self-assessment process and felt their voices were heard. On average, there was a 1 2 % increase in satisfaction across all themes from the start to end of the lab assessment. Conclusion: We successfully assessed the culture of our lab and subsequently improved lab member satisfaction. The success of this team project suggests that other scientific labs could benefit from similar interactive self-assessments.

Background: The balanced scorecard (BSC) has been implemented to evaluate the performance of health care organizations (HCOs). BSC proved to be effective in improving financial performance and patient satisfaction. Aim: This systematic review aims to identify key performance indicators (KPIs) and dimensions that are vital and most frequently used by health care managers in BSC implementations. Additionally, it attempts to analyze the resulting dimensions during the COVID-19 era. Methods: This systematic review adheres to PRISMA guidelines. The PubMed, Embase, Cochrane, and Google Scholar databases and Google search engine were inspected to find all implementations of BSC at HCO. The risk of bias was assessed using the nonrandomized intervention studies (ROBINS-I) tool to evaluate the quality of observational and quasi-experimental studies and the Cochrane (RoB 2) tool for randomized controlled trials (RCTs). Results: There were 33 eligible studies, of which we identified 36 BSC implementations. The categorization and regrouping of the 797 KPIs resulted in 46 subdimensions. The reassembly of these subdimensions resulted in 13 major dimensions: financial, efficiency and effectiveness, availability and quality of supplies and services, managerial tasks, health care workers (HCW) scientific development error-free and safety, time, HCW-centeredness, patient-centeredness, technology, and information systems, community care and reputation, HCO building, and communication. On the other hand, this review detected that BSC design modification to include external and managerial perspectives was necessary for many BSC implementations. Conclusion: This review solves the KPI categorization dilemma. It also guides researchers and health care managers in choosing dimensions for future BSC implementations and performance evaluations in general. Consequently, dimension uniformity will improve the data sharing and comparability among studies. Additionally, despite the pandemic negatively influencing many dimensions, the researchers observed a lack of comprehensive HCO performance evaluations. In the same vein, although some resulting dimensions were assessed separately during the pandemic, other dimensions still lack investigation. Lastly, BSC dimensions may play an essential role in tackling the COVID-19 pandemic. However, further research is required to investigate the BSC implementation effect in mitigating the pandemic consequences on HCO.

<li><strong>Emergence of a recurrent insertion in the N-terminal domain of the SARS-CoV-2 spike glycoprotein</strong> -
|
||
<div>
|
||
Tracking the evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through genomic surveillance programs is undoubtedly one of the key priorities in the current pandemic situation. Although the genome of SARS-CoV-2 acquires mutations at a slower rate compared with other RNA viruses, evolutionary pressures derived from the widespread circulation of SARS-CoV-2 in the human population have progressively favored the global emergence, though natural selection, of several variants of concern that carry multiple non-synonymous mutations in the spike glycoprotein. These are often placed in key sites within major antibody epitopes and may therefore confer resistance to neutralizing antibodies, leading to partial immune escape, or otherwise compensate infectivity deficits associated with other non-synonymous substitutions. As previously shown by other authors, several emerging variants carry recurrent deletion regions (RDRs) that display a partial overlap with antibody epitopes located in the spike N-terminal domain (NTD). Comparatively, very little attention has been directed towards spike insertion mutations prior to the emergence of the B.1.1.529 (omicron) lineage. This manuscript describes a single recurrent insertion region (RIR1) in the N-terminal domain of SARS-CoV-2 spike protein, characterized by at least 41 independent acquisitions of 1-8 additional codons between Val213 and Leu216 in different viral lineages. Even though RIR1 is unlikely to confer antibody escape, its association with two distinct formerly widespread lineages (A.2.5 and B.1.214.2), with the quickly spreading omicron and with other VOCs and VOIs warrants further investigation concerning its effects on spike structure and viral infectivity.

COVID-19 mortality disproportionately affected specific occupations and industries. The Occupational Safety and Health Administration (OSHA) protects the health and safety of workers by setting and enforcing standards for working conditions. Workers may file OSHA complaints about unsafe conditions. Complaints may indicate poor workplace safety during the pandemic. We evaluated COVID-19-related complaints filed with California (Cal)/OSHA between January 1, 2020 and December 14, 2020 across seven industries. To assess whether workers in occupations with high COVID-19-related mortality were also most likely to file Cal/OSHA complaints, we compared industry-specific per-capita COVID-19 confirmed deaths from the California Department of Public Health with COVID-19-related complaints. Although 7,820 COVID-19-related complaints were deemed valid by Cal/OSHA, only 627 onsite inspections occurred and 32 citations were issued. Agricultural workers had the highest per-capita COVID-19 death rates (402 per 100,000 workers) but were least represented among workplace complaints (44 per 100,000 workers). Health Care workers had the highest complaint rates (81 per 100,000 workers) but the second lowest COVID-19 death rate (81 per 100,000 workers). Industries with the highest inspection rates also had high COVID-19 mortality. Our findings suggest complaints are not proportional to COVID-19 risk. Instead, higher complaint rates may reflect worker groups with greater empowerment, resources, or capacity to advocate for better protections. This capacity to advocate for safe workplaces may account for relatively low mortality rates in potentially high-risk occupations. Future research should examine factors determining worker complaints and complaint systems to promote participation of those with the greatest need of protection.

<li><strong>Opening up safely: public health system requirements for ongoing COVID-19 management based on evaluation of Australia’s surveillance system performance</strong> -

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

Background Ongoing management of COVID-19 requires an evidence-based understanding of the performance of public health measures to date, and application of this evidence to evolving response objectives. This paper aims to define system requirements for COVID-19 management under future transmission and response scenarios, based on surveillance system performance to date. Methods From 1st November 2020 to 30th June 2021 community transmission was eliminated in Australia, allowing investigation of system performance in detecting novel outbreaks, including against variants of concern (VoCs). We characterised surveillance systems in place from peer-reviewed and publicly available data, analysed the epidemiological characteristics of novel outbreaks over this period, and assessed surveillance system sensitivity and timeliness in outbreak detection. These findings were integrated with analysis of other critical COVID-19 public health measures to establish requirements for future COVID-19 management. Findings Australia reported 25 epidemiologically distinct outbreaks and 5 distinct clusters of cases in the study period, all linked through genomic sequencing to breaches in quarantine facilities housing international travellers. Most (21/30, 70%) were detected through testing of those with acute respiratory illness in the community, and 9 through quarantine screening. For the 21 detected in the community, the testing rate (percent of the total State population tested in the week preceding detection) was 2.07% on average, was higher for those detected while prior outbreaks were ongoing. For 17/30 with data, the delay from the primary case to detection of the index case was, on average 4.9 days, with 10 of the 17 outbreaks detected within 5 days and 3 detected after > 7days. One outbreak was preceded by an unexpected positive wastewater detection. Of the 24 outbreaks in 2021, 20 had publicly available sequencing data, all of which were VoCs. Surveillance for future VoCs using a similar strategy to that used for detecting SARS-CoV-2 to date would necessitate a 100-1,000-fold increase in capacity for genomic sequencing. Interpretation Australia9s surveillance systems performed well in detecting novel introduction of SARS- CoV-2 in a period when community transmission was eliminated, introductions were infrequent and case numbers were low. Detection relied on community surveillance in symptomatic members of the general population and quarantine screening, supported by comprehensive genomic sequencing. Once vaccine coverage is maximised, the priority for future COVID-19 control will shift to detection of SARS-CoV-2 VoCs associated with increased severity of disease in the vaccinated and vaccine ineligible. This will require ongoing investment in maintaining surveillance systems and testing of all international arrivals, alongside greatly increased genomic sequencing capacity. Other essential requirements for managing VoCs are maintaining outbreak response capacity and developing capacity to rapidly engineer, manufacture, and distribute variant vaccines at scale. The most important factor in management of COVID-19 now and into the future will continue to be how effectively governments support all sectors of the community to engage in control measures.

<li><strong>Reconstructed signaling and regulatory networks identify potential drugs for SARS-CoV-2 infection</strong> -

<div>
|

Several molecular datasets have been recently compiled to characterize the activity of SARS-CoV-2 within human cells. Here we extend computational methods to integrate several different types of sequence, functional and interaction data to reconstruct networks and pathways activated by the virus in host cells. We identify key proteins in these networks and further intersect them with genes differentially expressed at conditions that are known to impact viral activity. Several of the top ranked genes do not directly interact with virus proteins. We experimentally tested treatments for a number of the predicted targets. We show that blocking one of the predicted indirect targets significantly reduces viral loads in stem cell-derived alveolar epithelial type II cells (iAT2s).

Genomic sequencing provides critical information to track the evolution and spread of SARS-CoV-2, optimize molecular tests, treatments and vaccines, and guide public health responses. To investigate the spatiotemporal heterogeneity in the global SARS-CoV-2 genomic surveillance, we estimated the impact of sequencing intensity and turnaround times (TAT) on variant detection in 167 countries. Most countries submit genomes >21 days after sample collection, and 77% of low and middle income countries sequenced <0.5% of their cases. We found that sequencing at least 0.5% of the cases, with a TAT <21 days, could be a benchmark for SARS-CoV-2 genomic surveillance efforts. Socioeconomic inequalities substantially impact our ability to quickly detect SARS-CoV-2 variants, and undermine the global pandemic preparedness.

Recent studies indicate that COVID-19 infection can lead to serious neurological consequences in a small percentage of individuals. However, in the months following acute illness, many more suffer from fatigue, low motivation, disturbed mood, poor sleep and cognitive symptoms, colloquially referred to as 9brain fog9. But what about individuals who had asymptomatic to moderate COVID-19 and report no concerns after recovering from COVID-19? Here we examined a wide range of cognitive functions critical for daily life (including sustained attention, memory, motor control, planning, semantic reasoning, mental rotation and spatial-visual attention) in people who had previously suffered from COVID-19 but were not significantly different from a control group on self-reported fatigue, forgetfulness, sleep abnormality, motivation, depression, anxiety and personality profile. Reassuringly, COVID-19 survivors performed well in most abilities tested, including working memory, executive function, planning and mental rotation. However, they displayed significantly worse episodic memory (up to 6 months post-infection) and greater decline in vigilance with time on task (for up to 9 months). Overall, the results show that specific chronic cognitive changes following COVID-19 are evident on objective testing even amongst those who do not report a greater symptom burden. Importantly, in the sample tested here, these were not significantly different from normal after six-nine months, demonstrating evidence of recovery over time.

<li><strong>Crises and social policy preferences: The impact of Covid-19 in Britain</strong> -
|
||
<div>
|
||
Do crises substantially change public support for taxes and spending, and why? We leverage the multifaceted character of the Covid-19 pandemic to test different theoretical micro-mechanisms usually confounded in observational research, or tested in isolation. Our randomized survey experiment provides four main findings. First, the economic and health dimensions of the crisis generated a substantial left-wing turn among the British public. Second, the effects are stronger on spending priorities (unemployment and health policies) than on who should pay for the welfare bill (progressivity of income and wealth taxes). Third, economic self-interested motivations are not relevant mechanisms to explain our findings. Fourth, framings associated with open borders and the global spread of the virus polarized welfare attitudes along immigration policy preferences. The generalizability of our findings, the prospects of redistributive conflicts after Covid, and the validity of established theories of welfare preferences in times of crisis are discussed.

ABSTRACT The deleterious effects relating to the COVID-19 pandemic on the mental health of healthcare workers has now been widely established. Understanding how COVID-19 affects their work and life is complex and multidimensional. This study describes the critical stressors and how they manifest within both the work and larger social environment for nurses and midwives in Tasmania, Australia. A longitudinal, descriptive survey was designed to explore the trajectory of the psychological health of Tasmanian public sector nurses and midwives during the COIVD-19 pandemic. The survey was distributed at 3 timepoints over a 12-month period and consisted of a battery of psychological tests which included the Patient Health Questionnaire, General Anxiety Disorder, Insomnia Severity Index, and the Impact of Events Scale-Revised, together with free text comments. The associations between outcome and predictor variables were assessed using mixed effects linear regression and linear mixed model analyses. Free text comments were themed. High levels of stress and mental exhaustion were attributed to threatened workplace team culture; compromised quality of patient care; the impact on family, home, financial and economic domains; lack of clear communication; issues surrounding personal protective equipment; and female gender. Study data show younger nurses and midwives suffered higher levels of stress and mental exhaustion than older. This study highlights the need for stable and functional relationships at home and at work for nurses and midwives. Factors which will help preserve the mental health of nurses and midwives include strong workplace culture with ongoing processes to monitor organisational burnout; building resilience, particularly among younger nurses and midwives; protection of healthcare worker safety; clear communication processes and supporting stable and functional relationships at home. The health service has an imperative to ensure optimum service delivery by safeguarding staff, despite the inevitable health stress imposed by the nature of the work.

<li><strong>Assessing real-world vaccine effectiveness against severe forms of SARS-CoV-2 infection from routine surveillance data in Switzerland</strong> -
|
||
<div>
|
||
Background. In Switzerland, SARS-CoV-2 vaccination campaigns started early 2021. Vaccine coverage reached 65% of the population in December 2021, mostly using mRNA vaccines from Moderna and Pfizer-BioNtech. Simultaneously, the proportion of vaccinated among COVID-19-related hospitalizations and deaths rose, creating some confusion in the general population. We aim to assess vaccine effectiveness against severe forms of SARS-CoV-2 infection using routine surveillance data on the vaccination status of COVID-19-related hospitalizations and deaths and data on vaccination coverage in Switzerland. Methods. We consider all routine surveillance data on COVID-19-related hospitalizations and deaths received at the Swiss Federal Office of Public Health from 1 July 2021 to 1 December 2021. We estimate the relative risk of COVID-19 related hospitalization or death for non-fully vaccinated compared to fully vaccinated individuals, adjusted for the dynamics of vaccination coverage over time, by age and location. We stratify the analysis by age group and by calendar month. We assess variations in the relative risk of hospitalization associated with the time since vaccination. Results. We include a total of 5,948 COVID-19-related hospitalizations of which 1,245 (21%) were fully vaccinated, and a total of 739 deaths of which 259 (35%) were fully vaccinated. We find that the relative risk of COVID-19 related hospitalization is 12.5 (95%CI: 11.7 to 13.4) times higher for non-fully vaccinated than for fully vaccinated individuals. This translates into a vaccine effectiveness against hospitalization of 92.0% (95%CI: 91.4 to 92.5%). Vaccine effectiveness against death is estimated to 90.3% (95%CI: 88.6 to 91.8%). Effectiveness appears comparatively lower in age groups over 70 and during the months of October and November 2021. We also find evidence of a decrease in vaccine effectiveness against hospitalization for individuals vaccinated for 25 weeks or more, but this decrease only appears in age groups below 70. Conclusions. The observed proportions of vaccinated among COVD-19-related hospitalizations and deaths in Switzerland are compatible with a high effectiveness of mRNA vaccines from Moderna and Pfizer-BioNtech against hospitalization and death in all age groups. Effectiveness appears comparatively lower in older age groups, suggesting the importance of booster vaccinations. We find inconclusive evidence that vaccine effectiveness is waning over time. Repeated analyses will be able to better assess waning and the effect of boosters.

<li><strong>Effectiveness of WhatsApp for measuring migration in follow-up phone surveys - Lessons from a mode experiment in two low-income countries during COVID contact restrictions</strong> -
|
||
<div>
|
||
Phone surveys have increasingly become important data collection tools in developing countries, particularly in the context of sudden contact restrictions due to the COVID-19 pandemic. Phone surveys offer particular potential for migration scholars aiming to study cross-border migration behavior. Geographic change of location over time complicates the logistics of face-to-face surveys and heavily increases costs. There is, however, limited evidence of the effectiveness of the phone survey modes in different geographic settings more generally, and in migration research more specifically. In this field experiment, we compared the response rates between WhatsApp—a relatively new but increasingly important survey mode—and interactive voice response (IVR) modes, using a sample of 8446 contacts in Senegal and Guinea. At 12%, WhatsApp survey response rates were nearly eight percentage points lower than IVR survey response rates. However, WhatsApp offers higher survey completion rates, substantially lower costs and does not introduce more sample selection bias compared to IVR. We discuss the potential of WhatsApp surveys in low-income contexts and provide practical recommendations for field implementation.

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

Evaluating the characteristics of emerging SARS-CoV-2 variants of concern is essential to inform pandemic risk assessment. A variant may grow faster if it produces a larger number of secondary infections (transmissibility advantage) or if the timing of secondary infections (generation time) is better. So far, assessments have largely focused on deriving the transmissibility advantage assuming the generation time was unchanged. Yet, knowledge of both is needed to anticipate impact. Here we develop an analytical framework to investigate the contribution of both the transmissibility advantage and generation time to the growth advantage of a variant. We find that the growth advantage depends on the epidemiological context (level of epidemic control). More specifically, variants conferring earlier transmission are more strongly favoured when the historical strains have fast epidemic growth, while variants conferring later transmission are more strongly favoured when historical strains have slow or negative growth. We develop these conceptual insights into a statistical framework to infer both the transmissibility advantage and generation time of a variant. On simulated data, our framework correctly estimates both parameters when it covers time periods characterized by different epidemiological contexts. Applied to data for the Alpha and Delta variants in England and in Europe, we find that Alpha confers a +54% [95% CI, 45-63%] transmissibility advantage compared to previous strains, and Delta +140% [98-182%] compared to Alpha, and mean generation times are similar to historical strains for both variants. This work helps interpret variant frequency and will strengthen risk assessment for future variants of concern.

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

The emergence of the Omicron variant (1) of SARS-CoV-2 in November 2021 in South Africa has raised concerns that, based on the large number of mutations in the spike protein and elsewhere on the virus (https://covdb.stanford.edu/page/mutation-viewer/#sec_b-1-351), this variant will have considerable escape from vaccine elicited immunity. Furthermore, several mutations in the receptor binding domain and S2 are predicted to impact transmissibility and affinity for ACE-2. Here we investigated whether Omicron escapes antibody neutralization elicited by the Pfizer BNT162b2 mRNA vaccine and whether the virus still requires binding to the ACE2 receptor to infect cells. We used an early passage of isolated and sequence confirmed live Omicron virus isolated in South Africa. We used a human lung cell line clone (H1299-ACE2) engineered to express the ACE2 receptor (2) to both isolate the virus and test neutralization. We also tested growth in the parental H1299 which do not overexpress ACE2 and are not appreciably infectable with SARS-CoV-2 (Fig S1). The H1299-ACE2 cells were similar to Vero-E6 in titer dependent focus formation, but were considerably more sensitive (Fig S2). We observed that Omicron infected the ACE2-expressing cells in a concentration dependent manner but did not infect the parental H1299 cells, indicating that ACE2 is required for Omicron entry (Fig. 1A). We then tested the ability of plasma from BNT162b2 vaccinated study participants to neutralize Omicron versus ancestral D614G virus in a live virus neutralization assay. We tested 14 plasma samples from 12 participants (Table S1), with 6 having no previous record of SARS-CoV-2 infection nor detectable nucleocapsid antibodies indicative of previous infection. For two of these participants, we used samples from two timepoints. The remaining 6 participants had a record of previous infection in the first SARS-CoV-2 infection wave in South Africa where infection was with ancestral D614G virus (Table S1). Geometric mean titer (GMT) FRNT50 (inverse of the plasma dilution required for 50% reduction in infection foci number) was 1321 for D614G. These samples therefore had very strong neutralization of D614G virus, consistent with sampling soon after vaccination. GMT FRNT50 for the same samples was 32 for Omicron, a 41-fold decline (Fig 1B). However, the escape was incomplete, with 5 of the participants, all previously infected, showing relatively high neutralization titers with Omicron. Beta variant escape from BNT162b2 in a live virus neutralization assay has been reported to be substantial (3) and our own data confirmed these results (4), with about 3-fold reduction in FRNT50. The results we present here with Omicron show much more extensive escape. However, escape was incomplete in participants with higher FRNT50 due to previous infection. Previous infection, followed by vaccination or booster is likely to increase the neutralization level and likely confer protection from severe disease in Omicron infection.

|

<div>
|

It has recently been shown that an early SARS-CoV-2 isolate (NL-02-2020) hijacks interferon-induced transmembrane proteins (IFITMs) for efficient replication in human cells. To date, several “Variants of Concern” (VOCs) showing increased infectivity and resistance to neutralization have emerged and globally replaced the early viral strains. Here, we determined whether the four SARS-CoV-2 VOCs (Alpha, Beta, Gamma and Delta) maintained the dependency on IFITM proteins for efficient replication. We found that depletion of IFITM2 strongly reduces viral RNA production by all four VOCs in the human epithelial lung cancer cell line Calu-3. Silencing of IFITM1 had little effect, while knock-down of IFITM3 resulted in an intermediate phenotype. Strikingly, depletion of IFITM2 generally reduced infectious virus production by more than four orders of magnitude. In addition, an antibody directed against the N-terminus of IFITM2 inhibited SARS-CoV-2 VOC replication in iPSC-derived alveolar epithelial type II cells thought to represent major viral target cells in the lung. In conclusion, endogenously expressed IFITM proteins (especially IFITM2) are critical cofactors for efficient replication of genuine SARS-CoV-2 VOCs, including the currently dominating Delta variant.

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