<li><strong>Concepts and methods for predicting viral evolution</strong> -
|
||
<div>
|
||
The seasonal human influenza virus undergoes rapid evolution, leading to significant changes in circulating viral strains from year to year. These changes are typically driven by adaptive mutations, particularly in the antigenic epitopes, the regions of the viral surface protein haemagglutinin targeted by human antibodies. Here we describe a consistent set of methods for data-driven predictive analysis of viral evolution. Our pipeline integrates four types of data: (1) sequence data of viral isolates collected on a worldwide scale, (2) epidemiological data on incidences, (3) antigenic characterization of circulating viruses, and (4) intrinsic viral phenotypes. From the combined analysis of these data, we obtain estimates of relative fitness for circulating strains and predictions of clade frequencies for periods of up to one year. Furthermore, we obtain comparative estimates of protection against future viral populations for candidate vaccine strains, providing a basis for pre-emptive vaccine strain selection. Continuously updated predictions obtained from the prediction pipeline for influenza and SARS-CoV-2 are available on the website https://previr.app.

Codon optimization describes the process used to increase protein production by use of alternative but synonymous codon changes. In SARS-CoV-2 mRNA vaccines codon optimizations can result in differential secondary conformations that inevitably affect a protein’s function with significant consequences to the cell. Importantly, when codon optimization increases the GC content of synthetic mRNAs, there can be an inevitable enrichment of G-quartets which potentially form G-quadruplex structures. The emerging G-quadruplexes are favorable binding sites of RNA binding proteins like helicases that inevitably affect epigenetic reprogramming of the cell by altering transcription, translation and replication. In this study, we performed a RNAfold analysis to investigate alterations in secondary structures of mRNAs in SARS-CoV-2 vaccines due to codon optimization. We show a significant increase in the GC content of mRNAs in vaccines as compared to native SARS-CoV-2 RNA sequences encoding the spike protein. As the GC enrichment leads to more G-quadruplex structure formations, these may contribute to potential pathological processes initiated by SARS-CoV-2 molecular vaccination.

<li><strong>Lateral Flow Assays Biotesting by Utilizing Plasmonic Nanoparticles Made of Inexpensive Metals - Replacing Colloidal Gold</strong> -
|
||
<div>
|
||
Nanoparticles (NPs) can be conjugated with diverse biomolecules and employed in biosensing to detect target analytes in biological samples. This proven concept was primarily used during the COVID-19 pandemic with gold NPs-based lateral flow assays (LFAs). Considering the gold price and its worldwide depletion, here we show that novel plasmonic nanoparticles (NPs) based on inexpensive metals, titanium nitride (TiN) and copper covered with a gold shell (Cu@Au), perform comparable or even better than gold nanoparticles. After conjugation, these novel nanoparticles provided high figures of merit for LFA testing, such as high signals and specificity and robust naked-eye signal recognition. To the best of our knowledge, our study represents the 1st application of laser-ablation-fabricated nanoparticles (TiN) in the LFA and dot-blot biotesting. Since the main cost of the Au NPs in commercial testing kits is in the colloidal synthesis, our development with TiN is very exciting, offering potentially very inexpensive plasmonic nanomaterials for various bio-testing applications. Moreover, our machine learning study showed that the bio-detection with TiN is more accurate than that with Au.

<li><strong>Hidden evolutionary constraints dictate the retention of coronavirus accessory genes</strong> -
|
||
<div>
|
||
Coronaviruses exhibit many mechanisms of genetic innovation (1-5), including the acquisition of accessory genes that originate by capture of cellular genes or through duplication of existing viral genes (6,7). Accessory genes influence viral host range and cellular tropism, but little is known about how selection acts on these variable regions of virus genomes. We used experimental evolution of mouse hepatitis virus (MHV) encoding a cellular AKAP7 phosphodiesterase and an inactive native phosphodiesterase, NS2 (ref 8) to simulate the capture of a host gene and analyze its evolution. After courses of serial infection, the gene encoding inactive NS2, ORF2, unexpectedly remained intact, suggesting it is under cryptic constraint uncoupled from the function of NS2. In contrast, AKAP7 was retained under strong selection but rapidly lost under relaxed selection. Guided by the retention of ORF2 and similar patterns in related betacoronaviruses, we analyzed ORF8 of SARS-CoV-2, which arose via gene duplication6 and contains premature stop codons in several globally successful lineages. As with MHV ORF2, the coding-defective SARS-CoV-2 ORF8 gene remains largely intact, mirroring patterns observed during MHV experimental evolution, challenging assumptions on the dynamics of gene loss in virus genomes and extending these findings to viruses currently adapting to humans.

<li><strong>Identification of unique and potent inhibitors of SARS-CoV-2 main protease from DNA-encoded chemical libraries</strong> -
|
||
<div>
|
||
In vitro screening of large libraries of compounds with automated High-throughput screening is expensive, time consuming and requires dedicated infrastructures. Conversely, the screening of DNA-encoded chemical libraries can be rapidly performed with basic equipment available in most laboratories. In this study we identified novel inhibitors of SARS-CoV-2 main protease (Mpro) through the affinity screening of the commercially available ''DELopen'' library, containing 4.2 billion compounds. The identified inhibitors were peptidomimetics compounds containing a C-terminal electrophilic group able to covalently bind to Mpro reactive Cys145 (confirmed by x-ray crystallography). Compound SLL11 had IC50 = 30nM and was found to be well optimized, proving that the rapid exploration of large chemical spaces, enabled by DECL technology, allows the direct identification of potent inhibitors avoiding several rounds of iterative medicinal chemistry. Compound MP6, a close analogue of SLL11, showed antiviral activity against SARS-CoV-2 in the low micromolar range when tested in Caco-2 and Calu-3 (EC50 = 2.3 M) cell lines. As peptidomimetics compounds can suffer from low cell permeability and metabolic stability, the cyclization of the compounds as well as the substitution of selected residues with D-enantiomers will be explored in the future to improve the antiviral activity of these novel compounds.

<li><strong>A Protein Language Model for Exploring Viral Fitness Landscapes</strong> -
|
||
<div>
|
||
Successively emerging SARS-CoV-2 variants lead to repeated epidemic surges through escalated spreading potential (i.e., fitness). Modeling genotype-fitness relationship enables us to pinpoint the mutations boosting viral fitness and flag high-risk variants immediately after their detection. Here, we introduce CoVFit, a protein language model able to predict the fitness of variants based solely on their spike protein sequences. CoVFit was trained with genotype-fitness data derived from viral genome surveillance and functional mutation data related to immune evasion. When limited to only data available before the emergence of XBB, CoVFit successfully predicted the higher fitness of the XBB lineage. Fully-trained CoVFit identified 549 fitness elevation events throughout SARS-CoV-2 evolution until late 2023. Furthermore, a CoVFit-based simulation was able to predict the higher fitness of JN.1 subvariants before their detection. Our study provides both insight into the SARS-CoV-2 fitness landscape and a novel tool potentially transforming viral genome surveillance.

<li><strong>Modulation of SARS-CoV-2 spike binding to ACE2 throughconformational selection</strong> -
|
||
<div>
|
||
The first step of SARS-CoV-2 infection involves the interaction between the trimeric viral spike protein () and the host angiotensin-converting enzyme 2 (2). The receptor binding domain () of adopts two conformations: open and closed, respectively, accessible and inaccessible to 2. Therefore, motions are suspected to affect 2 binding; yet a quantitative description of the underlying mechanism has been elusive. Here, using single-molecule approaches, we visualize opening and closing and probe the /2 interaction. Our results show that RBD dynamics affect 2 binding but not unbinding. The resulting modulation is quantitatively predicted by a conformational selection model in which each protomer behaves independently. Our work reveals a general molecular mechanism affecting binding affinity without altering binding strength, helping to understand coronavirus infection and immune evasion.

<li><strong>Binding of SARS-CoV-2 nucleocapsid protein to uninfected epithelial cells induces antibody-mediated complement deposition</strong> -
|

<div>
|

SARS-CoV-2 infection triggers strong antibody response toward Nucleocapsid-Protein (NP), suggesting extracellular presence beyond its intra-virion RNA binding. Interestingly, NP was found to decorate infected and proximal uninfected cell-surfaces. Here, we propose a new mechanism through which extracellular NP on uninfected cells contributes to COVID-19 pathogenicity. We show that NP binds to cell-surface sulfated linear-glycosaminoglycans by spatial rearrangement of its RNA-binding sites facilitated by the flexible, positively charged, linker. Coating of uninfected lung-derived cells with purified NP attracted anti-NP-IgG from lung fluids and sera collected from COVID-19 patients. The magnitude of this immune recognition was significantly elevated in moderate compared to mild COVID-19 cases. Importantly, binding of anti-NP-IgG present in sera generated clusters that triggered C3b deposition by the classical complement pathway. Heparin analog enoxaparin outcompeted NP-binding, rescuing cells from anti-NP IgG-mediated complement deposition. Our findings unveil how extracellular NP may exacerbate COVID-19 tissue damage, and suggest leads for preventative therapy.

<li><strong>CORACLE (COVID-19 liteRAture CompiLEr): A platform for efficient tracking and extraction of SARS-CoV-2 and COVID-19 literature, with examples from post-COVID with respiratory involvement</strong> -
|
||
<div>
|
||
Background: During COVID-19 pandemic there emerged a need to efficiently monitor and process large volumes of scientific literature on the subject. Currently, as the pandemic is winding down, the clinicians encountered a novel syndrome - Post-acute Sequelae of COVID-19 (PASC) - that affects over 10% of those who contract SARS-CoV-2 and presents a significant and growing challenge in the medical field. The continuous influx of new research publications underscores a critical need for efficient tools for navigating the literature. Objectives: We aimed to develop an application which will allow monitoring and categorizing COVID-19-related literature through building publication networks and medical subject headings (MeSH) maps to be able to quickly identify key publications and publication networks. Methods: We introduce CORACLE (COVID-19 liteRAture CompiLEr), an innovative web application designed for the analysis of COVID-19-related scientific articles and the identification of research trends. CORACLE features three primary interfaces: The "Search" interface, which displays research trends and citation links; the "Citation Map" interface, allowing users to create tailored citation networks from PubMed Identifiers (PMIDs) to uncover common references among selected articles; and the "MeSH" interface, highlighting current MeSH trends and associations between MeSH terms. Results: Our web application, CORACLE, leverages regularly updated PubMed data to aggregate and categorize the extensive literature on COVID-19 and PASC, aiding in the identification of relevant research publication hubs. Using lung function in PASC patients as a search example, we demonstrate how to identify and visualize the interactions between the relevant publications. Conclusion: CORACLE proves to be an effective tool for the extraction and analysis of literature. Its functionalities, including the MeSH trends and customizable citation mapping, facilitate the discovery of relevant information and emerging trends in COVID-19 and PASC research.

<li><strong>Young Parents’ Experiences of Pregnancy and Parenting during the COVID-19 Pandemic: A qualitative study in the United Kingdom</strong> -
|
||
<div>
|
||
Young parents (aged 16-24 years) in the perinatal period may be at an increased risk of poor mental health during the COVID-19 pandemic, due to multiple risk factors, including social and economic instability. COVID-19 related restrictions had significant implications for the delivery of some perinatal care services and other support structures for young parents. Investigating young parents’ experiences during the COVID-19 pandemic, including their perceived challenges and needs, is important to inform good practice and provide appropriate support for young parents. Qualitative interviews were conducted with young parents (n=21) during the COVID-19 pandemic in the United Kingdom from February – May 2021. Data were analysed using thematic analysis. Three key themes were identified to describe parents’ experiences during the COVID-19 pandemic. Parents reported specific COVID-19 related anxieties and stressors, including worries around contracting the virus and increased feelings of distress due to uncertainty created by the implications of the pandemic. Parents described feeling alone both at home and during antenatal appointments and highlighted the absence of social support as a major area of concern. Also, parents felt their perinatal care had been disrupted by the pandemic and experienced difficulties accessing care online or over the phone. This study highlights the potential impact of COVID-19 on young parents, including on their mental wellbeing and the perinatal support they were able to access during the pandemic. Insights from this study could inform the support and services offered to families during future pandemics. Specifically, the findings underlie the importance of (a) supporting both parents during perinatal appointments, (b) providing parents with early mental health support and (c) finding ways to facilitate communication pathways between professionals and parents.

<li><strong>Demographic and health factors associated with pandemic anxiety in the context of COVID-19</strong> -

Objectives The mental health consequences of COVID-19 are predicted to have a disproportionate impact on certain groups. We aimed to develop a brief measure, the Pandemic Anxiety Scale, to capture the specific aspects of the pandemic that are provoking anxiety, and explore how these vary by health and demographic factors. Design Data were from a convenience sample of parents (N=4,793) and adolescents (N=698) recruited in the first 6 weeks of lockdown. Methods Factor analytic and IRT methods were used to validate the new measure in both parent and adolescent samples. Associations between scores on the new measure and age, gender, household income, and physical health status were explored using structural equation modelling (SEM). Results Two factors were identified in both samples: disease-anxiety (e.g. catching, transmitting the virus) and consequence anxiety (e.g. impact on economic prospects), and unique associations with health and demographic factors were observed. Conclusions Anxieties due to the COVID-19 are multifaceted, and the PAS is a short, reliable and valid measure of these concerns. These anxieties are differentially associated with demographic, social and health factors, which should be considered when developing strategies to mitigate the mental health impact of the pandemic.

This manuscript is now published in open access UCL Open Environment: https://ucl.scienceopen.com/hosted-document?doi=10.14324/111.444/000092.v2 <strong>This manuscript has been submitted for publication and is likely to be edited as part of the peer-review process. Correspondence regarding this paper should be addressed to Keri Ka-Yee Wong, keri.wong@ucl.ac.uk.</strong> Background. The 2019 coronavirus (COVID-19) pandemic has impacted people’s mental wellbeing. Studies to date have examined the prevalence of mental health symptoms (anxiety, depression, loneliness), yet fewer longitudinal studies have compared across background factors and other psychological variables to identify vulnerable sub-groups. This study tests to what extent higher levels of psychotic-like experiences – indexed by schizotypal traits and paranoia – are associated with various mental health variables 6- and 12-months since April 2020. Methods. Over 2,300 adult volunteers (18-89 years, female=74.9%) with access to the study link online were recruited from the UK, USA, Greece, and Italy. Self-reported levels of schizotypy, paranoia, anxiety, depression, aggression, loneliness, and stress from three timepoints (17 April to 13 July 2020, N1 =1,599; 17 October to 31 January 2021, N2 =774; and 17 April to 31 July 2021, N3 =586) were mapped using network analysis and compared across time and background variables (sex, age, income, country). Results. Schizotypal traits and paranoia were positively associated with poorer mental health through loneliness, with no effect of age, sex, income levels, countries, and timepoints. Loneliness was the most influential variable across all networks, despite overall reductions in levels of loneliness, schizotypy, paranoia, and aggression during the easing of lockdown. Individuals with higher levels of schizotypal traits/paranoia reported poorer mental health outcomes than individuals in the low-trait groups. Conclusion. Schizotypal traits and paranoia are associated with poor mental health outcomes through self-perceived loneliness, suggesting that increasing social/community cohesion may improve individuals’ mental wellbeing in the long run.

Author Notes This is now published in BMJ Open on 5 May 2023: https://bmjopen.bmj.com/content/13/5/e071903.full <strong>This manuscript has been submitted for publication and is likely to be edited as part of the peer-review process. Correspondence regarding this paper should be addressed to Dr Keri Ka-Yee Wong, keri.wong@ucl.ac.uk</strong> Abstract Objectives The Covid-19 pandemic has disproportionately impacted vulnerable groups’ physical and mental health, especially young people and minority ethnic groups, yet little is known about how this is taking place and what support they would like. To address this gap, this qualitative study aims to uncover the effect of the Covid-19 outbreak on young people with ethnic minority backgrounds’ mental health, how this changed since the end of lockdown and what support they need to cope with these issues. Setting and Participants Ten 20-minute in-person semi-structured interviews were conducted with young people aged 12 to 17 years old from black and mixed-ethnic groups who regularly attend a community centre in West London. Results Through Interpretative Phenomenological Analysis, results indicated that the participants’ mental health was negatively impacted by the Covid-19 pandemic, with feelings of loneliness being the most common experience. However, positive effects were concurrently observed including improved well-being and better coping strategies post-lockdown, which is a testament to the young people’s resilience. That said, it is clear that young people from minority ethnic backgrounds lacked support during the Covid-19 pandemic and would now need psychological, practical and relational assistance to cope with these challenges. Conclusions Whilst future studies would benefit from a larger ethnically-diverse sample, this is a start. Study findings have the potential to inform future government policies around mental health support and access for young people from ethnic minorities, notably prioritising support for grassroots initiatives during times of crisis. Strengths and limitations • This qualitative interview study during Covid-19 gives voice to the experiences of young people from black and mixed-ethnic backgrounds in the UK • The in-person quality of the interviews helped build rapport between the researcher and the young people and sharing of sensitive issues around mental health access and support, increasing the results’ validity • This is a convenient sample, with girls and those aged 15 years and above being disproportionately represented in our data as they provided most of the answers. • The small sample size and lack of ethnic diversity limits the generalisability of the study to individuals from other ethnic minority groups.

<strong>This paper is now published in open access UCL Open Environment: https://ucl.scienceopen.com/hosted-document?doi=10.14324/111.444/000119.v2</strong>* The impact of the coronavirus 2019 (COVID-19) pandemic on different countries and populations is well documented in quantitative studies, with some studies showing stable mental health symptoms and others showing fluctuating symptoms. However, the reasons behind why some symptoms are stable and others change are under-explored, which in turn makes identifying the types of support needed by participants themselves challenging. To address these gaps, this study thematically analysed 925 qualitative responses from five open-ended responses collected in the UCL-Penn Global COVID Study between 17 April to 31 July 2021 (wave 3). Three key themes comprised of 13 codes were reported by participants across countries and ages regarding the impact of COVID-19 on their health, both mental and physical, and livelihoods. These include: 1) Outlook on self/life, 2) Self-improvement, and 3) Loved ones (friends and family). In terms of support, while 2.91% did not require additional support, 91% wanted support beyond financial. Other unexpected new themes were also discussed regarding vulnerable populations suffering disproportionately. The pandemic has brought into sharp focus various changes in people’s mental health, physical health, and relationships. Greater policy considerations should be given to supporting citizens’ continued access to mental health when considering pandemic recovery. Keywords: COVID-19; mental health; behavioural change; qualitative; financial burden; support.

Author Notes <strong>This manuscript is now published in open access UCL Open Environment: https://ucl.scienceopen.com/hosted-document?doi=10.14324/111.444/ucloe.000040</strong>. <strong>This manuscript has been submitted for publication and is likely to be edited as part of the peer-review process. Correspondence regarding this paper should be addressed to Keri Ka-Yee Wong, keri.wong@ucl.ac.uk.</strong> Abstract In this study we surveyed families’ experiences with parental depression, stress, relationship conflict, and child behavioral issues during six months of the COVID-19 pandemic through the COVID-19: Global Social Trust and Mental Health Study. The current analyses used data collected from online surveys completed by adults in 66 countries from April 17, 2020-July 14, 2020 (Wave I), followed by surveys six months later at Wave II (October 17, 2020-January 31, 2021). Analyses were limited to 175 adult parents who reported living with at least one child under 18 years old at Wave I. Parents reported on children’s level of externalizing and internalizing behavior at Wave I. At Wave II, parents completed self-reported measures of stress, depression, and inter-partner conflict. Child externalizing behavior at Wave I significantly predicted higher levels of parental stress and marginally predicted parental depression at Wave II, controlling for covariates. Child internalizing behavior at Wave I did not predict parental stress or depression, controlling for covariates. Neither child externalizing nor internalizing behavior predicted parental relationship conflict. The overall findings demonstrate that child behavior likely influenced parental stress and depression during the COVID-19 pandemic. Findings suggest that mental health interventions for children and parents may improve the family system during times of disaster.

According to that view, people drink because they cannot resist. In the present studies, we approached this from a different perspective and tested whether alcohol consumption might also be a problem of low hedonic capacity (i.e., people’s inability to experience pleasure and relaxation, often due to intrusive thoughts)….</p></li>
