<li><strong>Investigating orthographic versus auditory cross-situational word learning with online and lab-based research</strong> -
|
||
<div>
|
||
In recent years, cross-situational word learning (CSWL) paradigms have shown that novel words can be learned through implicit statistical learning. So far, CSWL studies using adult populations have focused on the presentation of spoken words (auditory information), however, words can also be learned through their written form (orthographic information). This study compares auditory and orthographic presentation of novel words with different degrees of phonological overlap using the CSWL paradigm. Additionally, we also present a lab-based and online-based approach to testing behavioural experiments. Due to the COVID-19 pandemic, lab testing was prematurely terminated, and testing was continued online using a newly created online testing protocol. Analyses first compared accuracy and response times across modalities, with our findings showing better and faster recognition performance for CSWL when novel words are presented through their written (orthographic condition) than through their spoken forms (auditory condition). As well, Bayesian modelling found that accuracy for the auditory condition was higher online compared to the lab-based experiment, whereas performance in the orthography condition was high in both experiments and generally outperformed the auditory condition. We discuss the implications of our findings for modality of presentation, as well as the benefits of our online testing protocol and its implementation for future research.

The begging of 2020 saw the development and trials of vaccines against Covid-19 at an unprecedented pace. The first half of 2021 has seen vaccine rollout in many countries, on the other hand, Immunity to covid-19 has exhibited to minimize the risk of having a severe infection and initiate an excellent degree against the disease. This study compares Anti-Spike IgG antibodies among vaccinated people with or without previous exposure to the coronavirus. To determine whether a single dose of sputnik V can produce significant antibody titer amongst previously infected cases and design vaccine dosage regimens accordingly. This study was performed at the Libyan biotechnology research Centre from August 2021 to December 2021. Blood samples were collected from 1811 adult males and females vaccinated with and without a history of exposure to covid-19. Previously infected individuals9 record was noted separately. Samples were immediately analyzed by Beckman Unicel Dxl 600, Access immunoassay system. Data were analyzed using GraphPad Prism 9 Software. A P-value >0.5 was not significant. The Majority of candidates 60% of the total samples were males and on analysis, it was found that 72% of patients were seropositive, on the other hand, individuals who were vaccinated and have naive antibodies from the previous infection showed slightly higher immunological response rather than vaccinated patients without previous infected and this finding can help the policymakers to design a single-dose vaccine regimen for the former category. Keywords: Sputnik V, COVID-19, Antibody, Vaccine.

Background Early evidence suggested that the impact of the COVID-19 pandemic was less severe in Africa compared to other parts of the world. However, more recent studies indicate higher SARS-CoV-2 infection and COVID-19 mortality rates on the continent than previously documented. Research is needed to better understand SARS-CoV-2 seroprevalence and immunity in Africa. Methods Our collaboration with the Lagos State COVID-19 Taskforce, enabled secondary analyses of immune responses in healthcare workers (HCWs) and Oxford/AstraZeneca COVID-19 vaccine recipients from the general population across 5 local government areas (LGAs) in Lagos State, Nigeria. Western blots were used to simultaneously detect SARS-CoV-2 spike and nucleocapsid (N) antibodies and stimulation of peripheral blood mononuclear cells with N followed by an IFN-γ ELISA was used to examine T cell responses. Findings Antibody data demonstrated high SARS-CoV-2 seroprevalence of 71.6% (96/134) in HCWs and 54.8% (63/115) in the general population. Antibodies directed to only SARS-CoV-2 N, suggesting pre-existing coronavirus immunity, were seen in 10.4% (14/134) of HCWs and 20.0% (23/115) of the general population. T cell data showed that IFN-γ responses against SARS-CoV-2 N were robust in detecting exposure to the virus, demonstrating 87.5% sensitivity and 92.3% specificity. Interpretation These results have important implications for understanding the paradoxical high SARS-CoV-2 infection with low mortality rate in Africa as compared to other parts of the world, as well as for the development of T cell-based diagnostics and vaccines.

Post-COVID-19 conditions, also known as long COVID, has significantly impacted the lives of many individuals, but the risk factors for this condition are poorly understood. In this study, we performed a retrospective EHR analysis of 89,843 individuals at a multi-state health system in the United States with PCR-confirmed COVID-19, including 1,086 patients diagnosed with long COVID and 1,086 matched controls not diagnosed with long COVID. For these two cohorts, we evaluated a wide range of clinical covariates, including laboratory tests, medication orders, phenotypes recorded in the clinical notes, and outcomes. We found that chronic pulmonary disease (CPD) was significantly more common as a pre-existing condition for the long COVID cohort than the control cohort (odds ratio: 1.9, 95% CI: [1.5, 2.6]). Additionally, long-COVID patients were more likely to have a history of migraine (odds ratio: 2.2, 95% CI: [1.6, 3.1]) and fibromyalgia (odds ratio: 2.3, 95% CI: [1.3, 3.8]). During the acute infection phase, the following lab measurements were abnormal in the long COVID cohort: high triglycerides (meanlongCOVID: 278.5 mg/dL vs. meancontrol: 141.4 mg/dL), low HDL cholesterol levels (meanlongCOVID: 38.4 mg/dL vs. meancontrol: 52.5 mg/dL), and high neutrophil-lymphocyte ratio (meanlongCOVID: 10.7 vs. meancontrol: 7.2). The hospitalization rate during the acute infection phase was also higher in the long COVID cohort compared to the control cohort (ratelongCOVID: 5% vs. ratecontrol: 1%). Overall, this study suggests that the severity of acute infection and a history of CPD, migraine, CFS, or fibromyalgia may be risk factors for long COVID symptoms. Our findings motivate clinical studies to evaluate whether suppressing acute disease severity proactively, especially in patients at high risk, can reduce incidence of long COVID.

<li><strong>SARS-CoV-2 mRNA vaccine is re-adenylated in vivo, enhancing antigen production and immune response</strong> -
|
||
<div>
|
||
Though mRNA vaccines against COVID-19 have revolutionized vaccinology and have been administered in billions of doses, we know incredibly little about how mRNA vaccines are metabolized in vivo. Here we implemented enhanced nanopore Direct RNA sequencing (eDRS), to enable the analysis of single Moderna’s mRNA-1273 molecules, giving in vivo information about the sequence and poly(A) tails. We show that mRNA-1273, with all uridines replaced by N1-methylpseudouridine (m Psi), is terminated by a long poly(A) tail (~100 nucleotides) followed by an mpsimpsi AG sequence. In model cell lines, mRNA-1273 is swiftly degraded in a process initiated by the removal of mPsiPsiAG, followed by CCR4-NOT-mediated deadenylation. In contrast, intramuscularly inoculated mRNA-1273 undergoes more complex modifications. Notably, mRNA-1273 molecules are re-adenylated after mPsimPsiAG removal. Detailed analysis of immune cells involved in antigen production revealed that in macrophages, after mPsimPsiAG removal, vaccine mRNA is very efficiently re-adenylated, and poly(A) tails can reach up to 200A. In contrast, in dendritic cells, vaccine mRNA undergoes slow deadenylation-dependent decay. We further demonstrate that enhancement of mRNA stability in macrophages is mediated by TENT5 poly(A) polymerases, whose expression is induced by the vaccine itself. Lack of TENT5-mediated re-adenylation results in lower antigen production and severely compromises specific immunoglobulin production following vaccination. Together, our findings provide an unexpected principle for the high efficacy of mRNA vaccines and open new possibilities for their improvement. They also emphasize that, in addition to targeting a protein of interest, the design of mRNA therapeutics should be customized to its cellular destination.

<li><strong>Immunopeptidome profiling of human coronavirus OC43-infected cells identifies CD4 T cell epitopes specific to seasonal coronaviruses or cross-reactive with SARS-CoV-2</strong> -
|
||
<div>
|
||
Seasonal “common-cold” human coronaviruses are widely spread throughout the world and are mainly associated with mild upper respiratory tract infections. The emergence of highly pathogenic coronaviruses MERS-CoV, SARS-CoV, and most recently SARS-CoV-2 has prompted increased attention to coronavirus biology and immunopathology, but identification and characterization of the T cell response to seasonal human coronaviruses remain largely uncharacterized. Here we report the repertoire of viral peptides that are naturally processed and presented upon infection of a model cell line with seasonal human coronavirus OC43. We identified MHC-I and MHC-II bound peptides derived from the viral spike, nucleocapsid, hemagglutinin-esterase, 3C-like proteinase, and envelope proteins. Only three MHC-I bound OC43-derived peptides were observed, possibly due to the potent MHC-I downregulation induced by OC43 infection. By contrast, 80 MHC-II bound peptides corresponding to 14 distinct OC43-derived epitopes were identified, including many at very high abundance within the overall MHC-II peptidome. These peptides elicited low-abundance recall T cell responses in most donors tested. In vitro assays confirmed that the peptides were recognized by CD4+ T cells and identified the presenting HLA alleles. T cell responses cross-reactive between OC43, SARS-CoV-2, and the other seasonal coronaviruses were confirmed in samples of peripheral blood and peptide-expanded T cell lines. Among the validated epitopes, S903-917 presented by DPA1<em>01:03/DPB1</em>04:01 and S1085-1099 presented by DRB1<em>15:01 shared substantial homology to other human coronaviruses, including SARS-CoV-2, and were targeted by cross-reactive CD4 T cells. N54-68 and HE128-142 presented by DRB1</em>15:01 and HE259-273 presented by DPA1<em>01:03/DPB1</em>04:01 are immunodominant epitopes with low coronavirus homology that are not cross-reactive with SARS-CoV-2. Overall, the set of naturally processed and presented OC43 epitopes comprise both OC43-specific and human coronavirus cross-reactive epitopes, which can be used to follow T cell cross-reactivity after infection or vaccination and could aid in the selection of epitopes for inclusion in pan-coronavirus vaccines.

<li><strong>The time divide: Reducing the barrier of a lack of spare time increased physical activity levels during the UK Government-enforced COVID-19 lockdown</strong> -
|
||
<div>
|
||
Background & Objective: Many individuals do not meet the World Health Organisation (2010) recommendations of 150 minutes of physical activity a week, often citing a lack of time as a key reason. The UK government-mandated lockdown for the global SARS-CoV-2 virus (COVID-19) pandemic provided an opportunity to investigate whether a potential increase in available time would lead to increased activity levels, and whether an increase in activity would correlate with improvements in mental health. Methods: An online survey investigated physical activity levels (time and intensity) at three separate intervals within one calendar year: firstly, for a typical week before the government-mandated lockdown; secondly, a week during lockdown (including measures of mental wellbeing); and finally in August 2020 - which re-assessed physical activity levels and mental wellbeing after the easing of some lockdown restrictions. Results: Whilst participants reported spending more time engaging in physical activity during lockdown compared to before (with those who perceived themselves to have more spare time reporting a greater increase than those who did not), there was no difference in the intensity of this activity. Additionally, there was a significant positive correlation between physical activity levels and mental wellbeing during the initial period of lockdown. Conclusions: Overall, the study demonstrated that, as hypothesised by the COM-B model, reducing one of the most commonly reported barriers (time) did increase physical activity levels. Importantly, it also showed that those who engaged in more physical activity also reported better mental health, which is particularly striking given the likely overall detrimental effect of being in lockdown.

<li><strong>Empathetic, old, and disgust-sensitive vs. comfort-seeking, misinformed, and rationalizing: Predictors and motives for mask-wearing behavior and vaccination intention during the COVID-19 pandemic</strong> -
|
||
<div>
|
||
Containing a pandemic requires that individuals adhere to measures such as wearing face-masks and get vaccinated. Therefore, identifying predictors and motives for both behaviors is of importance. Here, we study the decisions made by a cross-national sample in randomized hypothetical scenarios during the COVID-19 pandemic. Our results show that mask-wearing was predicted by empathic tendencies, germ aversion, and higher age, whilst belief in misinformation and presentation of an interaction partner as a family member lowered the safety standards. The main motives associated with taking the mask off included: rationalization, facilitating interaction, and comfort. Vaccination intention was positively predicted by empathy, and negatively predicted by belief in misinformation and higher costs of the vaccine. We found no effect of immunization status of the surrounding social group. The most common motive for vaccination was protection of oneself and others, whereas undecided and anti-vaccine groups reported doubts about the effectiveness and fear of side effects. Together, we identify main social and psychological predictors and motives of mask-wearing behavior and vaccination intention. The results highlight the importance of social context for mask-wearing, easy access to vaccines, empathy, and trust in publicly distributed information.

<li><strong>Lapses in the person radar: Attentional traits predict difficulty in interpersonal distancing</strong> -
|
||
<div>
|
||
Within the psychological literature and during the COVID-19 pandemic, the regulation of interpersonal distance has typically been viewed as a voluntary choice, with implications for public health interventions. Here we highlight that lapses in interpersonal distancing can also occur unintentionally. Using a novel measure across 3 undergraduate samples (total N = 1225) we found that almost all (>97%) participants reported unintentional lapses in maintaining interpersonal distance, with 16% experiencing such lapses frequently. Thirty percent of the variance in these reports was accounted for by attentional traits: Inattentive and hyperactive-impulsive ADHD symptoms jointly predicted difficulties with interpersonal distancing, with the former relationship fully mediated by hyperfocus and spontaneous mind-wandering. The results are consistent with a view of interpersonal distancing as attentionally demanding and hence vulnerable to unintentional lapses due to inattention. We discuss the implications for epidemiology, social cognition and functioning, and design of social spaces.

<li><strong>Fast and Accurate Maximum-Likelihood Estimation of Multi-Type Birth-Death Epidemiological Models from Phylogenetic Trees</strong> -

|

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|
||
Multi-type birth-death (MTBD) models are phylodynamic analogies of compartmental models in classical epidemiology. They serve to infer such epidemiological parameters as the average number of secondary infections R_e and the infectious time from a phylogenetic tree (a genealogy of pathogen sequences). The representatives of this model family focus on various aspects of pathogen epidemics. For instance, the birth-death exposed-infectious (BDEI) model describes the transmission of pathogens featuring an incubation period (when there is a delay between the moment of infection and becoming infectious, as for Ebola and SARS-CoV-2), and permits its estimation along with other parameters. With constantly growing sequencing data, MTBD models should be extremely useful for unravelling information on pathogen epidemics. However, existing implementations of these models in a phylodynamic framework have not yet caught up with the sequencing speed. Computing time and numerical instability issues limit their applicability to medium data sets (⩽ 500 samples), while the accuracy of estimations should increase with more data. We propose a new highly parallelizable formulation of ordinary differential equations for MTBD models. We also extend them to forests to represent situations when a (sub-)epidemic started from several cases (e.g. multiple introductions to a country). We implemented it for the BDEI model in a maximum likelihood framework using a combination of numerical analysis methods for efficient equation resolution. Our implementation estimates epidemiological parameter values and their confidence intervals in four minutes on a phylogenetic tree of 10 000 samples. Comparison to the existing implementations on simulated data shows that it is not only 30 000 times faster, but also more accurate. An application of our tool to the 2014 Ebola epidemic in Sierra-Leone is also convincing, with very fast calculation and precise estimates.

<li><strong>Adherence to and Motivations for Complying with Public Health Measures Among Adolescents During the Coronavirus Disease (COVID-19) Pandemic in Canada</strong> -
|
||
<div>
|
||
Background: Public health measures (e.g., minimizing social interactions, social distancing, mask wearing) have been implemented in Canada to reduce the transmission of COVID-19. Given that adolescents may be a high-risk demographic for spreading COVID-19, this study investigated adherence to and motivations for complying with public health measures among youth living in Canada at two points of the COVID-19 pandemic. Methods: Adolescents (N = 1484, 53% female, Mage = 15.73 [SD = 1.41]) completed an online survey in either Summer 2020 (W1; n = 809, 56% female) or Winter 2020/2021 (W2; n = 675, 50% female). Independent sample t-tests investigated differences in adherence across waves and regression analyses examined predictors of adherence. Results: Youth engaged in similar levels of social interactions at W1 and W2. Relative to W1, adolescents reported more mask wearing, but less social distancing at W2. At both waves, social responsibility and not wanting to get sick predicted mask wearing, and social responsibility predicted social distancing. Being concerned with population health predicted adherence to all public health measures at W1, whereas concern with family health predicted adherence to mask wearing and social distancing at W2. Conclusions: Youth engaged in more mask wearing but less social distancing as the pandemic progressed. Social responsibility and not wanting to get sick were consistent predictors of adherence throughout the pandemic. Youth shifted from adhering to public health measures due to concern with population health to concern with family health as the pandemic progressed. These results can inform targeted campaigns to bolster compliance with public health measures among adolescents.

<li><strong>Longitudinal Profile of Post traumatic symptoms in HealthCare Workers during COVID-19 pandemic: A latent transition model</strong> -
|
||
<div>
|
||
Introduction: Pandemics have the potential to be considered traumatic event, increasing the risk of developing post-traumatic stress symptoms (PTSS) in some populations, such as Health Care Workers. However, few longitudinal studies have evaluated the impact of prolonged exposure to the risk imposed by COVID-19. Methods: We evaluated the levels of post-traumatic stress symptoms and psychological distress in a Brazilian HealthCare Workers’ sample (n = 1398) in three waves of assessment: from May to June 2020 (Wave 1), December 2020 to February 2021 (Wave 2) and May to August 2021 (Wave 3). Results: Using Latent Profile Analysis (LPA), it was identified two profiles: high-PTSS profile (Wave 1 - 23%; Wave 2 - 64% and Wave 3 - 73%) and low-PTSS (Wave 1 - 77%; Wave 2 - 36% and Wave 3 - 27%). Then, we used Latent Transition Analysis (LTA) to examine changes in symptom profiles over time, including gender, psychiatric diagnosis history, and pandemic-related fears as covariates. Results show that being female, working with fear of contamination, and fearing financial problems were strong predictors of changes in the profile from low-PTSS to high-PTSS. In addition, regardless of the initial profile, the participants had a high probability of being in the high-PTSS in the long run. Conclusion: There is a clear risk for HealthCare Workers to feel traumatized during a stressful critical healthcare condition.

<li><strong>Protocol for a Study on Día de los Muertos, Loss, Funerals, and Mental Health Among Mexican-Origin Adults in the United States</strong> -
|
||
<div>
|
||
Día de los Muertos is a traditional celebration takes place early in November and is one of the most intricate death-related ritual in Mexican culture in which families welcome the return of their loved ones who died. Funerals are important rituals following the death of a person that provide the bereaved with an opportunity to say farewell to the departed in company of family, friends, and community. Día de los Muertos and funerals can help process grief and loss following the COVID-19 pandemic, a global event that disproportionally affected Mexican-origin adults in the U.S. Although research has shown the cultural importance of participating in Día de los Muertos and funerals, less is known about their connection to each other, as well as grief, mental health, and wellbeing among those who experienced loss during the pandemic. In this protocol, we describe the rationale for a cross-sectional survey, a study using a correlational design, and present the research questions, sample characteristics, procedure, instrument, and data analysis plan. In Study 1, we will investigate the association between Día de los Muertos participation and attitudes with levels of grief, mental health, and wellbeing among those who experienced loss during the pandemic. In Study 2, we will examine the association between funeral participation and attitudes with levels of grief, mental health, and wellbeing among those who experienced loss during the pandemic.

Fathers experienced high rates of mental health concerns during the COVID-19 pandemic. Social support is crucial to mitigate these problems; however, access to and quality of support were impacted by public health guidelines to increase physical distancing. Online forums offer an avenue for peer connection and support. Yet, minimal research has examined forum use during COVID-19 to describe the experiences, perceived stressors, and resource need of fathers during the pandemic. This study qualitatively analyzed fathers’ experiences through a Framework Analytic Approach of reddit’s sub-forum r/daddit. Posts (N=299) and comments (N=2597) between July and October 2020 were analyzed. Findings highlighted five main themes (with subthemes): forum use, family functioning, psychological and health factors, interpersonal functioning, and COVID-19. First and foremost, fathers used the online forum to provide support and advice to other fathers. Main themes are discussed in terms of informing the development of services to support father and family wellbeing.

The “Mental Health Impact of COVID-19 Pandemic on NIMH Patients and Volunteers” study was a longitudinal study launched in spring 2020 by researchers at NIMH, to investigate the effect of the emerging COVID-19 pandemic on mental health. For each participant, the study collected personal characteristics, such as demographics, psychological traits, and clinical history, together with personal circumstances at regular intervals during their enrollment in the study. In this paper, we examine the degree to which a variety of mental health outcomes over time for an individual can be predicted from personal characteristics and their changing circumstances, using regression models trained on other study participants. We find that it is possible to predict the variation of a participant’s mental health outcomes from time point to time point, for most of the outcomes we consider. This capability is dominated by information about outcome at the point of enrollment in the study, but can be improved by considering personal characteristics and circumstances.
