<li><strong>Assessing the potential impact of immunity waning on the dynamics of COVID-19: an endemic model of COVID-19</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
We developed an endemic model of COVID-19 to assess the impact of vaccination and immunity waning on the dynamics of the disease. Our model exhibits the phenomenon of backward bifurcation and bi-stability, where a stable disease-free equilibrium co-exists with a stable endemic equilibrium. The epidemiological implication of this is that the control reproduction number being less than unity is no longer sufficient to guarantee disease eradication. We showed that this phenomenon could be eliminated by either increasing the vaccine efficacy or by reducing the disease transmission rate (adhering to non-pharmaceutical interventions). Furthermore, we numerically investigated the impacts of vaccination and waning of both vaccine-induced immunity and post-recovery immunity on the disease dynamics. Our simulation results show that the waning of vaccine-induced immunity has more effect on the disease dynamics relative to post-recovery immunity waning, and suggests that more emphasis should be on reducing the waning of vaccine-induced immunity to eradicate COVID-19.

<li><strong>Predicting willingness to be vaccinated for Covid-19: evidence from New Zealand</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Governments around the world are seeking to slow the spread of Covid-19 and reduce hospitalisations by encouraging mass vaccinations for Covid-19. The success of this policy depends on most of the population accepting the vaccine and then being vaccinated. Understanding and predicting the motivation of individuals to be vaccinated is, therefore, critical in assessing the likely effectiveness of a mass vaccination programme in slowing the spread of the virus. In this paper we draw on the I3 Response Framework to understand and predict the willingness of New Zealanders to be vaccinated for Covid-19. The Framework differs from most studies predicting willingness to be vaccinated because it is based on the idea that the willingness to adopt a behaviour depends on both involvement (a measure of motivational strength) with the behaviour and attitudes towards the behaviour. We show that predictions of individuals willingness to be vaccinated are improved using involvement and attitudes together, compared to attitudes alone. This result has important implications for the implementation of mass vaccination programmes for Covid-19.

<li><strong>Occupational versus community risk of SARS-CoV-2 infection among employees of a long-term care facility: an observational study</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Objectives: We investigated the relative contribution of occupational (vs. community) exposure for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among employees of a university-affiliated long-term care facility (LTCF), during the 1st pandemic wave in Switzerland (March to June 2020). Methods: We performed a nested analysis of a seroprevalence study among all volunteering LTCF staff to determine community and nosocomial risk factors for SARS-CoV-2 seropositivity using modified Poison regression. We also combined epidemiological and genetic sequencing data from a coronavirus disease 2019 (COVID-19) outbreak investigation in a LTCF ward to infer transmission dynamics and acquisition routes of SARS-CoV-2, and evaluated strain relatedness using a maximum likelihood phylogenetic tree. Results: Among 285 LTCF employees, 176 participated in the seroprevalence study, of whom 30 (17%) were seropositive for SARS-CoV-2. Most (141/176, 80%) were healthcare workers (HCWs). Risk factors for seropositivity included exposure to a COVID-19 inpatient (adjusted prevalence ratio [aPR] 2.6; 95%CI 0.9-8.1) and community contact with a COVID-19 case (aPR 1.7; 95%CI 0.8-3.5). Among 18 employees included in the outbreak investigation, the outbreak reconstruction suggests 4 likely importation events by HCWs with secondary transmissions to other HCWs and patients. Conclusions: These two complementary epidemiologic and molecular approaches suggest a substantial contribution of both occupational and community exposures to COVID-19 risk among HCWs in LTCFs. These data may help to better assess the importance of occupational health hazards and related legal implications during the COVID-19 pandemic.

<li><strong>Ambivalence and Adherence to Recommendations to Reduce the Spread of COVID-19</strong> -
<div>
Governments worldwide still (Oct. 2021), to some extent, rely on behavioral recommendations to reduce the spread of COVID-19. We examine the role of ambivalence towards both the specific recommendations (micro-ambivalence) and the pandemic as a whole (macro-ambivalence) with regard to compliance. We predict that micro ambivalence relates negatively, whereas macro ambivalence relates positively, to self-reported adherence to recommendations. We present two studies (N = 691) supporting our hypotheses: the more ambivalent people are towards the behavioral recommendations (micro level), the less they report following them. Conversely, the more ambivalent people are about the pandemic as a whole (macro level), the more they report following recommendations. Our findings replicated in a U.S. sample and a representative German sample.

<li><strong>Access and quality of sexual and reproductive health (SRH) services in Britain during the early stages of the COVID-19 pandemic: a qualitative interview study of patient experiences</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Objectives: Access to quality sexual and reproductive health (SRH) services remains imperative, even during a pandemic. Our objective was to understand experiences of delayed or unsuccessful access to SRH services in Britain during the early stages of COVID-19 pandemic. Design: Semi-structured qualitative follow-up interviews were conducted in October-November 2020 (six months after the first UK lockdown) with participants of Natsal-COVID, a quasi- representative web-panel survey of sexual health and behaviour during COVID-19 (n=6654). Inductive thematic analysis was used to identify lessons for future SRH service access and quality. Setting: Telephone interviews with participants from the general population. Participants: 14 women and 6 men (24-47-years-old) reporting unmet need for SRH services and agreeing to recontact (n=311) were selected for interview using socio-demographic quotas. Results: Participant experiences spanned ten different SRH services, including contraception and antenatal/maternity services. At interview, ten participants still experienced unmet need. Participants reported hesitancy and self-censorship of need. Accessing services required tenacity. Challenges included navigating inconsistent information and changing procedures; perceptions of gatekeepers as obstructing access; and inflexible appointment systems. Concerns about reconfigured services included reduced privacy; decreased quality of interactions with professionals; reduced informal support due to lone attendance; and fewer routine physical checks. However, participants also described examples of more streamlined services and staff efforts to compensate for disruptions. Many viewed the blending of telemedicine with in-person care as a positive development. Conclusion: COVID-19 impacted access and quality of SRH services. The accounts of those who struggled to access services revealed self-censorship of need, difficulty navigating shifting service configurations, and perceived reduction in quality due to a socially-distanced service model. Telemedicine offers potential for greater efficiency if blended intelligently with in-person care. We offer some initial data-based recommendations for promoting equitable access and quality in restoration and future adaption of SRH services.

<li><strong>Seroprevalence, prevalence, and genomic surveillance: monitoring the initial phases of the SARS-CoV-2 pandemic in Betim, Brazil</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
The Covid-19 pandemic has created an unprecedented need for epidemiological monitoring using diverse strategies. We conducted a project combining prevalence, seroprevalence, and genomic surveillance approaches to describe the initial pandemic stages in Betim City, Brazil. We collected 3239 subjects in a population-based age-, sex- and neighborhood-stratified, household, prospective; cross-sectional study divided into three surveys 21 days apart sampling the same geographical area. In the first survey, overall prevalence (participants positive in serological or molecular tests) reached 0.46% (90% CI 0.12% - 0.80%), followed by 2.69% (90% CI 1.88% - 3.49%) in the second survey and 6.67% (90% CI 5.42% - 7.92%) in the third. The underreporting reached 11, 19.6, and 20.4 times in each survey, respectively. We observed increased odds to test positive in females compared to males (OR 1.88 95% CI 1.25 - 2.82), while the single best predictor for positivity was ageusia/ anosmia (OR 8.12, 95% CI 4.72 - 13.98). Thirty-five SARS-CoV-2 genomes were sequenced, of which 18 were classified as lineage B.1.1.28, while 17 were B.1.1.33. Multiple independent viral introductions were observed. Integration of multiple epidemiological strategies was able to describe Covid-19 dispersion in the city adequately. Presented results have helped local government authorities to guide pandemic management.

<li><strong>Impact of biologics and small molecules for Inflammatory Bowel Disease on COVID-19 Related Hospitalization: A Systematic Review and Meta-analysis</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background The use of biological therapies and small molecules have been a concern for patients with inflammatory bowel disease (IBD) during COVID-19 pandemic. We aim to assess the association between risk of COVID-19 related hospitalization and these agents. Method A systematic review and meta-analysis of all published studies from December 2019 to September 2021 was performed to identify studies that reported COVID-19 related hospitalization in IBD patients receiving biological therapies or tofacitinib. The risk ratio (RR) was calculated to compare the relative risk of COVID-19 related hospitalization in patients receiving these medications to those who were not, at the time of the study. Results 18 studies were included. The relative risk of hospitalization was significantly lower in patients with IBD and COVID-19 who were receiving biologic therapy with RR of 0.47 (95% CI: 0.42-0.52, p &lt; 0.00001). The RR was lower in patients receiving anti-TNFs compared to those who did not [RR= 0.48 (95% CI: 0.41-0.55, p &lt; 0.00001)]. Similar finding was observed in patients taking ustekinumab [RR= 0.55 (95% CI: 0.43-0.72, p &lt; 0.00001)]. Combination therapy of anti-TNF and an immunomodulator did not lower the risk of COVID-19 related hospitalization [RR= 0.98 (95% CI: 0.82-1.18, p =0.84]. The use of vedolizumab [RR= 1.13 (95% CI: 0.75-1.73, p =0.56] and tofacitinib [RR= 0.81 (95% CI: 0.49-1.33, p =0.40] was not associated with lower risk of COVID-19 related hospitalization. Conclusion Regarding COVID-19 related hospitalization in IBD, anti-TNFs and ustekinumab were associated with favorable outcomes. In addition, vedolizumab and tofacitinib were not associated with COVID-19 related hospitalization.

<li><strong>Leaders gender and the fight against COVID-19: investigation, replication, and a possible explanation</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Objectives To investigate the alleged relationship between leaders gender and COVID-19 related cases and deaths in different countries across the globe. Study design The relationship between leaders gender and percent of women in parliament to COVID-19 cases and death per million was investigated in three time points (10 months) across 180 countries, controlling for possible covariates. Methods Three different types of analyses were run: (1) Six basic t-tests; (2) Two repeated-measure ANOVA tests analyzing change over time; (3) Six stepwise regression analyses for both leaders gender and the percentage of women in parliament. Results Our findings suggest that, contrary to some research and popular media headlines, and in-line with recent academic research, leadership gender is not a significant factor in explaining the variation between countries in the fight against the COVID-19 pandemic. Conclusions We suggest that this alleged relationship may stem from an illusory correlation. We argue that the uncertainty, stress, and anxiety that prevail in these times of global pandemic may be the breeding ground for judgmental biases of this sort.

<li><strong>A randomized, controlled, feasibility study of RD-X19 in patients with mild-to-moderate COVID-19 in the outpatient setting</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
These studies aimed to further understand the antiviral effects of safe, visible light and demonstrate a therapeutic effect of an investigational treatment device for outpatients with mild to moderate COVID-19. RD-X19 is a handheld medical device precisely engineered to emit blue light through the oral cavity to target the oropharynx and surrounding tissues. At doses that are well-tolerated in an in vitro human epithelial tissue model, the monochromatic visible light delivered by RD-X19 results in light-initiated expression of IL-1α and IL-1β cytokines with corresponding inhibition of SARS-CoV-2 replication. A randomized, double-blind, sham-controlled early feasibility study using the investigational device enrolled 31 subjects with a positive SARS-CoV-2 antigen test and possessing at least two moderate COVID-19 signs and symptoms. Subjects were randomized 2:1 (RD-X19 to sham), treated twice daily for four days, and evaluated over one week. Prespecified outcome measures included assessments of SARS-CoV-2 viral load and clinical assessments of COVID-19. There were no local application site reactions and no device-related adverse events. The time- weighted average change in log viral load throughout the study demonstrated a favorable reduction for RD-X19 compared to sham and at the end of study the mean change in log10 viral load was -3.29 for RD-X19 and -1.81 for sham at Day 8, demonstrating a treatment benefit of -1.48 [95% confidence internal (CI), -2.88 to -0.071]. Among the clinical outcome measures, differences between RD-X19 and sham were also observed, with a 57-hour reduction of median time to sustained resolution of COVID-19 signs and symptoms.

<li><strong>Establishing CREATE: Lessons learned in setting up a training environment for early-career researchers in respiratory medicine</strong> -
<div>
Background: The purpose of the National Health and Medical Research Council Centre of Research Excellence in Pulmonary Fibrosis (CRE-PF) is to improve and extend the lives of patients living with pulmonary fibrosis through the development of a comprehensive and integrated program of basic and clinical research and education across Australia. A key objective of the CRE-PF was establishment of a unique national training scheme, CREATE, for early-career researchers (ECRs) in respiratory research. CREATE ECRs are broadly drawn from two main fields of researchers: clinicians and scientists, where clinicians tend to be involved in part-time translational research and scientists are involved in broad scientific research including laboratory or genetic research, health economics or population research. Methods: We describe the CREATE Program which, with limited budget and the assistance of key organisations, has provided funding opportunities (scholarships, fellowships, prizes, travel and collaboration grants), professional development (mentoring program, symposia, presentation opportunities and on-line training) and fostered a connected, supportive research community for respiratory ECRs. Results: The CREATE program has successfully fostered the development of the supported researchers, contributing substantially to the future of pulmonary fibrosis research in Australia. During the life of the program the CRE-PF has offered 10 PhD scholarships and five postdoctoral fellowships, awarded 13 travel grants and three grants to promote collaboration between ECRs from different institutes. A mentoring program has been established and CREATE Symposia have been held in association with key meetings. During COVID-19 restrictions, a series of virtual research meetings has offered 12 CREATE ECRs from seven universities the opportunity to present their research to a national audience. CREATE research-related achievements are impressive, including over 80 first-author publications by ECRs, and many conference presentations. Contributions to the research community, measured by committee membership, is also strong. Conclusions: In spite of a very limited budget, wide geographic distribution of participants and the multi- disciplinary nature of the cohort, we have succeeded in providing a unique, supportive academic development environment for CREATE ECRs. Lessons learned in the process of developing this program include the importance of leveraging funding, being flexible, building networks and seeking and responding to ECR input.

<li><strong>Spatial transcriptomic characterization of COVID-19 pneumonitis identifies immune circuits related to tissue injury</strong> -
<div>
Severe lung damage in COVID-19 involves complex interactions between diverse populations of immune and stromal cells. In this study, we used a spatial transcriptomics approach to delineate the cells, pathways and genes present across the spectrum of histopathological damage in COVID-19 lung tissue. We applied correlation network-based approaches to deconvolve gene expression data from areas of interest within well preserved post-mortem lung samples from three patients. Despite substantial inter-patient heterogeneity we discovered evidence for a common immune cell signaling circuit in areas of severe tissue that involves crosstalk between cytotoxic lymphocytes and pro-inflammatory macrophages. Expression of IFNG by cytotoxic lymphocytes was associated with induction of chemokines including CXCL9, CXCL10 and CXCL11 which are known to promote the recruitment of CXCR3+ immune cells. The tumour necrosis factor (TNF) superfamily members BAFF (TNFSF13B) and TRAIL (TNFSF10) were found to be consistently upregulated in the areas with severe tissue damage. We used published spatial and single cell SARS-CoV-2 datasets to confirm our findings in the lung tissue from additional cohorts of COVID-19 patients. The resulting model of severe COVID-19 immune-mediated tissue pathology may inform future therapeutic strategies.

In March 2020, the Global Consortium of Chemosensory Research (GCCR) was founded by chemosensory researchers to address then emerging reports of unusual smell and taste dysfunction arising from the SARS-CoV-2 pandemic. Over the next year, the GCCR used a highly collaborative model, along with contemporary Open Science practices, to produce multiple high impact publications on chemosensation and COVID19. This invited manuscript describes the founding of the GCCR, the tools and approaches it used, and a summary of findings to date. These findings are contextualized within a summary of some of the broader insights about chemosensation (smell, taste, and chemesthesis) and COVID19 gained over the last 18 months, including potential mechanisms of loss. Also, it includes a detailed discussion of some current Open Science approaches and practices used by the GCCR to increase transparency, rigor, and reproducibility.

<li><strong>Conflicts of interest and physicians’ attitudes towards hydroxychloroquine as a treatment against COVID-19: A replication and extension of Roussel &amp; Raoult (2020)</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Hydroxychloroquine (HCQ) and its use as a treatment against COVID-19 have been at the center of heated debates. Some claim that the hostility of physicians towards HCQ was partly orchestrated by rival pharmaceutical companies seeking to promote their own treatment. In favor of this hypothesis, Roussel and Raoult (2020) have presented the results of a study in which they find a perfect positive correlation (ρ = 1.00) between French physicians9 attitudes towards HCQ and their conflict of interest with Gilead Sciences - the company that has promoted Remdesivir (REM) as a treatment against COVID-19. However, Roussel and Raoult9s study suffers from serious methodological shortcomings, among which is the fact that the statistical methods they employed might tend to artificially inflate correlations. In this study, we use a similar method and sample, but correct for their study s original shortcomings: we provide a detailed, pre-registered method for collecting and coding data, computer inter-rater agreement and use a wide array of appropriate statistical methods to achieve a more reliable estimate the association between conflicts of interest and physicians attitudes towards HCQ. We conclude that Roussel and Raoult s conclusion was misguided and that financial conflicts of interest were not the main predictors of the attitudes of physicians when compared to other factors, such as academic affiliation. Moreover, compared to other pharmaceutical companies, there was no specific link between attitudes towards HCQ and conflicts of interest with Gilead Sciences.
