<li><strong>COVID-19 and neuroinflammation: A vital role for dance therapy in long-term health outcomes</strong> -
|
||
<div>
|
||
There is mounting evidence that COVID-19 infection is related to neuroinflammation, which can lead to the development of neurodegenerative conditions such as Parkinson’s and Alzheimer’s Diseases. Holistic, mind-body tools and techniques commonly used in dance therapy directly support neural mechanisms that may help prevent or slow this process. This article reviews recent biological research on the development and progress of COVID-19 and outlines the connection between infection and neurodegenerative illness, while indicating a clear role for dance therapy in pandemic response and recovery.

|

While humoral immune responses to infection or vaccination with ancestral SARS-CoV-2 have been well-characterized, responses elicited by infection with variants are less understood. Here we characterized the repertoire, epitope specificity, and cross-reactivity of antibodies elicited by Beta and Gamma variant infection compared to ancestral virus. We developed a high-throughput approach to obtain single-cell immunoglobulin sequences and isolate monoclonal antibodies for functional assessment. Spike-, RBD- and NTD-specific antibodies elicited by Beta- or Gamma-infection exhibited a remarkably similar hierarchy of epitope immunodominance for RBD and convergent V gene usage when compared to ancestral virus infection. Additionally, similar public B cell clones were elicited regardless of infecting variant. These convergent responses may account for the broad cross-reactivity and continued efficacy of vaccines based on a single ancestral variant.

The COVID-19 pandemic has resulted in millions of deaths and affected socioeconomic structure worldwide and the search for new antivirals and treatments are still ongoing. In the search for new drug target and to increase our understanding of the disease, we used large scale immunofluorescence to explore the host cell response to SARS-CoV-2 infection. Among the 602 host proteins studied in this host response screen, changes in abundance and subcellular localization were observed for 97 proteins, with 45 proteins showing increased abundance and 10 reduced abundances. 20 proteins displayed changed localization upon infection and an additional 22 proteins displayed altered abundance and localization, together contributing to diverse reshuffling of the host cell protein landscape. We then selected existing and approved small-molecule drugs (n =123) against our identified host response proteins and identified 3 compounds</div></li>

<li><strong>Discovery of a druggable copper-signaling pathway that drives cell plasticity and inflammation</strong> -
|
||
<div>
|
||
Inflammation is a complex physiological process triggered in response to harmful stimuli. It involves specialized cells of the immune system able to clear sources of cell injury and damaged tissues to promote repair. Excessive inflammation can occur as a result of infections and is a hallmark of several diseases. The molecular basis underlying inflammatory responses are not fully understood. Here, we show that the cell surface marker CD44, which characterizes activated immune cells, acts as a metal transporter that promotes copper uptake. We identified a chemically reactive pool of copper(II) in mitochondria of inflammatory macrophages that catalyzes NAD(H) redox cycling by activating hydrogen peroxide. Maintenance of NAD+ enables metabolic and epigenetic programming towards the inflammatory state. Targeting mitochondrial copper(II) with a rationally-designed dimer of metformin triggers distinct metabolic and epigenetic states that oppose macrophage activation. This drug reduces inflammation in mouse models of bacterial and viral infections (SARS-CoV-2), improves well-being and increases survival. Identifying mechanisms that regulate the plasticity of immune cells provides the means to develop next-generation medicine. Our work illuminates the central role of copper as a regulator of cell plasticity and unveils a new therapeutic strategy based on metabolic reprogramming and the control of epigenetic cell states.

<li><strong>A mosaic-type trimeric RBD-based COVID-19 vaccine candidate induces potent neutralization against Omicron and other SARS-CoV-2 variants</strong> -
|
||
<div>
|
||
Large-scale populations in the world have been vaccinated with COVID-19 vaccines, however, breakthrough infections of SARS-CoV-2 are still growing rapidly due to the emergence of immune-evasive variants, especially Omicron. It is urgent to develop effective broad-spectrum vaccines to better control the pandemic of these variants. Here, we present a mosaic-type trimeric form of spike receptor-binding domain (mos-tri-RBD) as a broad-spectrum vaccine candidate, which carries the key mutations from Omicron and other circulating variants. Tests in rats showed that the designed mos-tri- RBD, whether used alone or as a booster shot, elicited potent cross-neutralizing antibodies against not only Omicron but also other immune-evasive variants. Neutralizing antibody titers induced by mos-tri-RBD were substantially higher than those elicited by homo-tri-RBD (containing homologous RBDs from prototype strain) or the inactivated vaccine BBIBP-CorV. Our study indicates that mos-tri-RBD is highly immunogenic, which may serve as a broad-spectrum vaccine candidate in combating SARS-CoV-2 variants including Omicron.

<div>

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|
||
Background During the COVID-19 pandemic, aerosol spread of SARS-CoV-2 has been a major problem in healthcare facilities, resulting in increased use of supplementary HEPA filtration to mitigate transmission. We report here a natural experiment that occurred when an air filtration unit (AFU) on an inpatient ward for older people was accidentally switched off. Aim To assess aerosol transport within the ward and determine whether the AFU reduced particulate matter (PM) levels in the air. Methods Time-series PM, CO2, temperature and humidity data (at 1 minute intervals) was collected from multiple sensors around the ward over two days in August 2021. During this period, the AFU was accidentally switched off for approximately 7 hours, allowing the impact of the intervention on particulates (PM1-PM10) to be assessed using a Mann-Whitney test. Pearson correlation analysis of the PM and CO2 signals was also undertaken to evaluate the movement of airborne particulates around the ward. Findings The AFU greatly reduced PM counts of all sizes throughout the ward space (p<0.001 for all sensors), with PM signals positively correlated with indoor CO2 levels (r = 0.343-0.817; all p<0.001). Aerosol particle counts tended to rise and fall simultaneously throughout the ward space when the AFU was off, with PM signals from multiple locations highly correlated (e.g. r = 0.343-0.868 (all p<0.001) for PM1). Conclusion Aerosols freely migrated between the various sub-compartments of the ward, suggesting that social distancing measures alone cannot prevent nosocomial transmission of SARS-CoV-2. The AFU greatly reduced PM levels throughout the ward space.

<li><strong>Genomic Epidemiology of SARS-CoV-2 in Seychelles, 2020-2021</strong> -

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

Seychelles, an archipelago of 155 islands in the Indian Ocean, had confirmed 24,788 cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by the 31st December 2021. The first SARS-CoV-2 cases in Seychelles were reported on the 14th of March 2020, but cases remained low until January 2021, when a surge of SARS-CoV-2 cases was observed on the islands. Here, we investigated the potential drivers of the surge by genomic analysis 1,056 SARS-CoV-2 positive samples collected in Seychelles between 14th March 2020 and 31st December 2021. The Seychelles genomes were classified into 32 Pango lineages, 1,042 of which fell within four variants of concern i.e., Alpha, Beta, Delta and Omicron. Sporadic cases of SARS-CoV-2 detected in Seychelles in 2020 were mainly of lineage B.1 (European origin) but this lineage was rapidly replaced by Beta variant starting January 2021, and which was also subsequently replaced by the Delta variant in May 2021 that dominated till November 2021 when Omicron cases were identified. Using ancestral state reconstruction approach, we estimated at least 78 independent SARS-CoV-2 introduction events into Seychelles during the study period. Majority of viral introductions into Seychelles occurred in 2021, despite substantial COVID-19 restrictions in place during this period. We conclude that the surge of SARS-CoV-2 cases in Seychelles in January 2021 was primarily due to the introduction of more transmissible SARS-CoV-2 variants into the islands.

Major stressors often challenge emotional well-being—increasing negative emotions and decreasing positive emotions. But how long do these emotional hits last? Prior theory and research contain conflicting views. Some research suggests that most individuals’ emotional well-being will return to, or even surpass, baseline levels relatively quickly. Others have challenged this view, arguing that this type of resilient response is uncommon. The present research provides a strong test of resilience theory by examining emotional trajectories over the first six months of the COVID-19 pandemic. In two pre-registered longitudinal studies (total N =1,147), we examined average emotional trajectories and predictors of individual differences in emotional trajectories across 13 waves of data from February through September</div></li>

<li>The pandemic had immediate detrimental effects on average emotional well-being. Across the next six months, average negative emotions returned to baseline levels with the greatest improvements occurring almost immediately. Yet, positive emotions remained depleted relative to baseline levels, illustrating the limits of typical resilience. Individuals differed substantially around these average emotional trajectories and these individual differences were predicted by socio-demographic characteristics and stressor exposure. We discuss theoretical implications of these findings that we hope will contribute to more nuanced approaches to studying, understanding, and improving emotional well-being following major stressors.

Since the beginning of 2020, the coronavirus disease (COVID-19) and its lockdowns have changed the current lives of young people drastically. Given the importance of future orientations for young people’s mental well-being, it is important to investigate if and how this lockdown affected young people’s future orientations. In this study, 34 Dutch young people (aged 16-24) with diverse backgrounds were interviewed during the lockdown of spring 2020 in the Netherlands. Results showed that young people experienced effects of COVID-19 on their current lives and short-term futures, but according to these young people, their long-term futures were not affected by the first COVID-19 lockdown. The latter finding may be explained by young people’s assumed temporality of the pandemic, their general optimistic attitudes, two-track thinking, strong feelings of agency, and flexibility.

<li><strong>The use of digital technologies by people with mild to moderate dementia during the COVID-19 pandemic: A positive technology perspective</strong> -
|
||
<div>
|
||
A growing body of research has shown that people with dementia are using digital technologies to enhance lived experience. The COVID-19 pandemic has brought new digital opportunities and challenges and so provides a unique opportunity to understand how people with dementia have adapted to this new digital landscape. Semi-structured interviews were conducted with 19 people with dementia and analysed thematically. We generated five themes, showing how participants used digital means to combat the stresses of the pandemic by facilitating social connection, self- actualisation, enhanced well-being and by assisting with activities of daily life. These technologies helped to reduce isolation, provide access to support groups, create opportunities for cognitive stimulation and self-development, and engendered a sense of identity at a time of perceived loss. Despite these benefits, participants also reported challenges regarding cognitive fatigue and usability issues. We recommend that training on how to use digital technologies is co-produced with people with dementia and designers engage with the voices of people with dementia throughout the design process. In turn, this could promote the social connectedness, well-being and self-worth of people with dementia.

<li><strong>The widening of inequalities in COVID-19 years of life lost from 2020 to 2021: a Scottish Burden of Disease study</strong> -
|
||
<div>
|
||
Background: Previous studies have highlighted the large extent of inequality in adverse COVID-19 health outcomes. Our aim was to monitor changes in the overall, and inequalities in COVID-19 years of life lost to premature mortality (YLL) in Scotland from 2020 and 2021. Methods: Cause-specific COVID-19 mortality counts were derived at age-group and area-deprivation level using Scottish death registrations for 2020 and 2021. YLL was estimated by multiplying mortality counts by age-conditional life expectancy from the Global Burden of Disease 2019 reference life table. Various measures of absolute and relative inequality were estimated for triangulation purposes. Results: There were marked inequalities in COVID-19 YLL by area deprivation in 2020, which were further exacerbated in 2021; confirmed across all measures of absolute and relative inequality. Half (51%) of COVID-19 YLL was attributable to inequalities in area deprivation in 2021, an increase from 41% in 2020. Conclusion: Despite a highly impactful vaccination programme in preventing mortality, COVID-19 continues to represent a substantial area of fatal population health loss for which inequalities have widened. Tackling systemic inequalities with effective interventions are required to mitigate further unjust health loss in the Scottish population from COVID-19 and other causes of ill-health and mortality.

<li><strong>Repeated ethanol exposure and withdrawal alters ACE2 expression in discrete brain regions: Implications for SARS- CoV-2 infection</strong> -
|
||
<div>
|
||
Emerging evidence suggests that people with alcohol use disorders are at higher risk for SARS-CoV-2. SARS-CoV-2 engages angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2) receptors for cellular entry. While ACE2 and TMPRSS2 genes are upregulated in the cortex of alcohol-dependent individuals, information on expression in specific brain regions and neural populations implicated in SARS-CoV-2 neuroinvasion, particularly monoaminergic neurons, is limited. We sought to clarify how chronic alcohol exposure affects ACE2 and TMPRSS2 expression in monoaminergic brainstem circuits and other putative SARS-CoV-2 entry points. C57BL/6J mice were exposed to chronic intermittent ethanol (CIE) vapor for 4 weeks and brains were examined using immunofluorescence. We observed increased ACE2 levels in the olfactory bulb and hypothalamus following CIE, which are known to mediate SARS-CoV-2 neuroinvasion. Total ACE2 immunoreactivity was also elevated in the raphe magnus (RMG), raphe obscurus (ROB), and locus coeruleus (LC), while in the dorsal raphe nucleus (DRN), ROB, and LC we observed increased colocalization of ACE2 with monoaminergic neurons. ACE2 also increased in the periaqueductal gray (PAG) and decreased in the amygdala. Whereas ACE2 was detected in most brain regions, TMPRSS2 was only detected in the olfactory bulb and DRN but was not significantly altered after CIE. Our results suggest that previous alcohol exposure may increase the risk of SARS-CoV-2 neuroinvasion and render brain circuits involved in cardiovascular and respiratory function as well as emotional processing more vulnerable to infection, making adverse outcomes more likely. Additional studies are needed to define a direct link between alcohol use and COVID-19 infection.

<li><strong>CD169-mediated restrictive SARS-CoV-2 infection of macrophages induces pro-inflammatory responses</strong> -
|
||
<div>
|
||
Exacerbated and persistent innate immune response marked by pro-inflammatory cytokine expression is thought to be a major driver of chronic COVID-19 pathology. Although macrophages are not the primary target cells of SARS-CoV-2 infection in humans, viral RNA and antigens in activated monocytes and macrophages have been detected in post-mortem samples, and dysfunctional monocytes and macrophages have been hypothesized to contribute to a protracted hyper- inflammatory state in COVID-19 patients. In this study, we demonstrate that CD169, a myeloid cell specific I-type lectin, facilitated ACE2-independent SARS-CoV-2 fusion and entry in macrophages. CD169-mediated SARS-CoV-2 entry in macrophages resulted in expression of viral genomic and sub-genomic (sg) RNAs with minimal viral protein expression and no infectious viral particle release, suggesting a post-entry restriction of the SARS-CoV-2 replication cycle. Intriguingly this post-entry replication block was alleviated by exogenous ACE2 expression in macrophages. Restricted expression of viral gRNA and sgRNA in CD169 + macrophages elicited a pro-inflammatory cytokine expression (TNF , IL-6 and IL-1 {beta}) in a RIG-I, MDA-5 and MAVS-dependent manner, which was suppressed by remdesivir pre-treatment. These findings suggest that de novo expression of SARS-CoV-2 RNA in macrophages contributes to the pro-inflammatory cytokine signature and that blocking CD169-mediated ACE2 independent infection and subsequent activation of macrophages by viral RNA might alleviate COVID-19-associated hyperinflammatory response.

|
||
<div>
|
||
The COVID-19 pandemic has had a staggering impact on social, economic, and public health systems worldwide. Vaccine development and mobilization against SARS-CoV-2 (the etiologic agent of COVID-19) has been rapid. However, novel strategies are still necessary to slow the pandemic, and this includes new approaches to vaccine development and/or delivery, which improve vaccination compliance and demonstrate efficacy against emerging variants. Here we report on the immunogenicity and efficacy of a SARS-CoV-2 vaccine comprised of stabilized, pre-fusion Spike protein trimers displayed on a ferritin nanoparticle (SpFN) adjuvanted with either conventional aluminum hydroxide or the Army Liposomal Formulation QS-21 (ALFQ) in a cynomolgus macaque COVID-19 model. Vaccination resulted in robust cell-mediated and humoral responses and a significant reduction of lung lesions following SARS-CoV-2 infection. The strength of the immune response suggests that dose sparing through reduced or single dosing in primates may be possible with this vaccine. Overall, the data support further evaluation of SpFN as a SARS-CoV-2 protein-based vaccine candidate with attention to fractional dosing and schedule optimization.

In a peer group, the similarity function was adaptive to edge information and local noise level, which was utilized for detecting the similarity among pixels. In addition, a new filtering method Modified Trilateral Filter (MTF) with Improved Generalized Fuzzy Peer Group (IGFPG) is proposed to remove mixed impulse and Adaptive White Gaussian Noise from Color Images. The modified trilateral filter includes Kikuchi algorithm and loopy belief propagation to solve the inference issues on the basis of passing local message. In this research work, the images were collected from KODAK dataset and a few real time multimedia images like Lena were also used for testing the effectiveness of the proposed methodology. - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN351884428">link</a></p></li>

In this patent we exercise machine literacy to measure SARS-COV-2 content, which is deceptively evident, online, which leads to establishment of health guidance, particularly about vaccinations. We plant that the anti-vax community is developing a less focused debate around SARS-COV-2 than its counterpart, the pro-vaccination community. Yet, the opposing-vax collaborative displays a wider range of motifs related to SARS-COV-2, and hence the information can appeal to a broader sampling of individualities seeking SARS-COV-2 guidance online, for illustration individualities cautious of a obligatory fast-tracked SARS-COV-2 vaccine or those seeking volition remedies. Hence, the opposing-vax community aspects more deposited to attract fresh support going forward when compared to pro-vax community. The fashion ability of opposing-vax community leads wide lack of relinquishment of a SARS-COV-2 vaccine, which means the world falls short of furnishing herd impunity, leaving countries open to unborn SARS-COV-2 reanimations. We give a mechanistic model that infers these results and could help in assessing the likely efficacity of intervention strategies.
