<li><strong>Trust in scientists and non-populist governments supports COVID-19 information and safeguarding behaviors</strong> -
|
||
<div>
|
||
Understanding how health communication influences engagement in protective health behaviors is crucial in the handling of pandemics, and especially the COVID-19 pandemic which has been branded an ‘infodemic’ due to the presence of misinformation and conspiracy theories. Here we investigate this through a large-scale survey in twelve countries (N = 7,755). We found, in line with our hypotheses, that trust in non-populist governments and scientists and their media predicted scientific knowledge, whereas distrust predicted conspiracy belief, together with trust in populist governments and social media. Scientific knowledge but not conspiracy belief in turn predicted safety guideline behaviors, whereas conspiracy belief but not scientific knowledge predicted misguided, self-centered behaviors like hoarding. However, conspiracy belief also predicted safety guideline behaviors, possibly due to the threat a presumed artificially created virus presents. We conclude that the communication of scientific knowledge through trusted sources is pivotal to adherence to safety guidelines during this and future health threats.

<li><strong>Zero COVID is Possible but Preventing Coronavirus Transmission is Not the Path to this Noble Reality</strong> -
|
||
<div>
|
||
Upon visualizing the reality in which biological phenomena occur with the Einsteinian method which does not make logical deductions in order to construct concepts such as those of the immunological kind which have eluded us since the birth of the repeatedly proven germ theory, it was found that immunological mechanisms do not protect us from the severe outcomes of the event in which the infectious disease (the disease the pathogen causes) is brought about by eliminating the pathogen but rather by permitting us to harbor the pathogen without the occurrence or completion of this event. Cases are therefore not direct consequences of infection but of the absence of immunological conditions that permit uneventful hosting of the pathogen so that infection goes undetected in the population when such protective conditions are widespread. And the noble goal of Zero COVID can only be achieved in a population in which the coronavirus is already harbored uneventfully through measures that ensure the presence and persistence of such immunological conditions and not through those such as lockdowns that aim to prevent coronavirus transmission on the basis of the assumption that cases occur in such a population as a direct consequence of community transmission. Given that vaccination does not protect from suffering and death by eliminating the coronavirus and those who have already been infected undetected cannot be protected by measures that aim to prevent community transmission, the elucidation of such immunological conditions with the goal of achieving Zero COVID ought to be the topmost priority of countries that are determined to put an end to the deaths that follow the co-manifestation of the different diseases in the COVID-19 spectrum long before those ages which the rare humans who celebrate their 110th birthdays approach more than all before they succumb to the outcomes of pathological events.

Rapid developments and methodological divides hinder the study of how scientific knowledge accumulates, consolidates and transfers to the public sphere. Our work proposes using Wikipedia, the online encyclopedia, as a historiographical source regarding contemporary science. We chose the high-profile field of gene editing as our test case, performing a historical analysis of the English-language Wikipedia articles on CRISPR. Using a mixed method approach, we qualitatively and quantitatively analyzed its text, sections and references, alongside 50 affiliated articles. These, we found, documented CRISPR’s maturation from a fundamental scientific discovery to a biotechnological revolution with vast social and cultural implications. We developed automated tools to support such research generically and demonstrated its applicability on two other scientific fields we have previously studied - COVID-19 and Circadian clocks. This method makes use of Wikipedia as a digital and free archive, documenting the incremental growth of knowledge and the manner scientific research accumulates and translates into public discourse. Using Wikipedia in this manner compliments and overcomes some issues with contemporary histories and can also augment existing bibliometric research.

<li><strong>Atomic-level characterization of the conformational transition pathways in SARS-CoV-1 and SARS-CoV-2 spike proteins</strong> -
|
||
<div>
|
||
Severe acute respiratory syndrome (SARS) coronaviruses 1 and 2 (SARS-CoV-1 and SARS-CoV-2) derive transmissibility from spike protein activation in the receptor binding domain (RBD) and binding to the host cell angiotensin converting enzyme 2 (ACE2). However, the mechanistic details that describe the large-scale conformational changes associated with spike protein activation or deactivation are still somewhat unknown. Here, we have employed an extensive set of nonequilibrium all-atom molecular dynamics (MD) simulations, utilizing a novel protocol, for the SARS-CoV-1 (CoV-1) and SARS-CoV-2 (CoV-2) prefusion spike proteins in order to characterize the conformational pathways associated with the active-to-inactive transition. Our results indicate that both CoV-1 and CoV-2 spike proteins undergo conformational transitions along pathways unique to each protein. We have identified a number of key residues that form various inter-domain salt-bridges, suggesting a multi-stage conformational change along the pathways. We have also constructed the free energy profiles along the transition pathways for both CoV-1 and CoV-2 spike proteins. The CoV-2 spike protein must overcome larger free energy barriers to undergo conformational changes towards protein activation or deactivation, when compared to CoV-1.

Wastewater-based epidemiology (WBE) has emerged as a powerful public health tool to trace new outbreaks, detect trends in infection and provide an early warning of COVID-19 community spread. Here, we investigated the spread of SARS-CoV-2 infections across Utah by characterizing lineages and mutations detected in wastewater samples. We sequenced over 1,200 samples from 32 sewersheds collected between November 2021 and March 2022. Wastewater sequencing confirmed the presence of Omicron (B.1.1.529) in Utah in samples collected on November 19, 2021, up to seven days before its corresponding detection via clinical sequencing. We observed an increase in prevalence of several Omicron-defining mutations across sewersheds from December to January. Proportion of Omicron increased to ~58% by January 4th 2022 and completely displaced Delta by February 7th, 2022. Our study shows that WBE is an excellent complementary tool to SARS-CoV-2 clinical surveillance and can guide public health action and policy decisions.

Respiratory syncytial virus (RSV) infections and hospitalization have surged sharply among young children. Here we test how the seasonal patterns of RSV infections in 2022 compared with those from other COVID-19 pandemic and pre-pandemic years. For this purpose, we analyzed a nation-wide and real-time database of electronic health records of 56 million patients across 50 states in the US. The monthly incidence rate of first-time RSV infection in young children (0-5 years of age) and very young children (0-1 year of age) followed a seasonal pattern from 2010 to 2019 with increases during the autumn, peaking in winter, subsiding in spring and summer. This seasonal pattern was significantly disrupted during the COVID-19 pandemic. In 2020, the incidence rate of RSV infections was remarkably low throughout the year. In 2021, the RSV season expanded to 9 months starting in the early summer and peaking in October. In 2022, RSV infections started to rise in May and were significantly higher than in previous years reaching a historically highest incidence rate in November 2022. There were significant racial and ethnic disparities in the peak RSV infection rate during 2010-2021 and the disparities further exacerbated in 2022 with peak incidence rate in black and Hispanic children 2-3 times that in white children. Among RSV-infected children in 2022, 19.2% had prior documented COVID-19 infection, significantly higher than the 9.7% among uninfected children, suggesting that prior COVID-19 could be a risk factor for RSV infection or that there are common risk factors for both viral infections. Our study calls for continuous monitoring of RSV infection in young children alongside its clinical outcomes and for future work to assess potential COVID-19 related risk factors.

SARS-CoV-2 infection can manifest as a wide range of respiratory and systemic symptoms well after the acute phase of infection in over 50% of patients. Key questions remain on the long-term effects of infection on tissue pathology in recovered COVID-19 patients. To address these questions we performed multiplexed imaging of post-mortem lung tissue from 12 individuals who died post-acute COVID-19 (PC) and compare them to lung tissue from patients who died during the acute phase of COVID-19, or patients who died with idiopathic pulmonary fibrosis (IPF), and otherwise healthy lung tissue. We find evidence of viral presence in the lung up to 359 days after the acute phase of disease, including in patients with negative nasopharyngeal swab tests. The lung of PC patients are characterized by the accumulation of senescent alveolar type 2 cells, fibrosis with hypervascularization of peribronchial areas and alveolar septa, as the most pronounced pathophysiological features. At the cellular level, lung disease of PC patients, while distinct, shares pathological features with the chronic pulmonary disease of IPF. which may help rationalize interventions for PC patients. Altogether, this study provides an important foundation for the understanding of the long-term effects of SARS-CoV-2 pulmonary infection at the microanatomical, cellular, and molecular level.

<li><strong>Calpain-2 mediates SARS-CoV-2 entry and represents a therapeutic target</strong> -
|
||
<div>
|
||
Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, much effort has been dedicated to identifying effective antivirals against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A number of calpain inhibitors show excellent antiviral activities against SARS-CoV-2 by targeting the viral main protease (Mpro), which plays an essential role in processing viral polyproteins. In this study, we found that calpain inhibitors potently inhibited the infection of a chimeric vesicular stomatitis virus (VSV) encoding the SARS-CoV-2 spike protein, but not Mpro. In contrast, calpain inhibitors did not exhibit antiviral activities towards the wild-type VSV with its native glycoprotein. Genetic knockout of calpain-2 by CRISPR/Cas9 conferred resistance of the host cells to the chimeric VSV-SARS-CoV-2 virus and a clinical isolate of wild-type SARS-CoV-2. Mechanistically, calpain-2 facilitates SARS-CoV-2 spike protein-mediated cell attachment by positively regulating the cell surface levels of ACE2. These results highlight an Mpro-independent pathway targeted by calpain inhibitors for efficient viral inhibition. We also identify calpain-2 as a novel host factor and a potential therapeutic target responsible for SARS-CoV-2 infection at the entry step.

While the effort to vaccinate people against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has largely been successful, particularly in the developed world, the rise of new variants as well as waning immunity illustrate the need for a new generation of vaccines that provide broader and/or more durable protection against infection and severe disease. Here we describe the generation and characterization of IVX-411, a computationally designed, two-component virus-like particle (VLP) displaying the ancestral SARS-CoV-2 receptor binding domain (RBD) on its surface. Immunization of mice with IVX-411 generates neutralizing antibodies against the ancestral strain as well as three variants of concern. Neutralizing antibody titers elicited by IVX-411 are durable and significantly higher than those elicited by immunization with soluble RBD and spike antigens. Furthermore, immunization with IVX-411 is shown to be protective in a Syrian Golden hamster challenge model using two different strains of SARS-CoV-2. Overall, these studies demonstrate that IVX-411 is highly immunogenic and capable of eliciting broad, protective immunity.

<li><strong>Exploring Views of Technology to Inform Maternal and Child Health Interventions for Black Birthing People</strong> -

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

Background: Black birthing people experience disproportionately higher rates of morbidity and mortality, and poorer infant health outcomes than all other racial and ethnic groups. Statewide in Wisconsin, an alarming disparity exists between Black and Non-Hispanic White (NHW) breastfeeding initiation rates (54% and 87%, respectively). For the last fourteen years, the African American Breastfeeding Network (AABN) has operated in Milwaukee County, where 70% of the Black population of Wisconsin lives. The mission of AABN is to improve maternal health and champion breastfeeding equity for Black birthing families. In 2018, AABN received more referrals than could be served by their team of doulas, lactation consultants, and advocates, leading our team to pursue ways to expand their reach through technology-based approaches. With the onset of COVID-19, the need for telehealth support increased drastically, as referrals for AABN services tripled. In this study, we explore the use of technology to support Black birthing families in Wisconsin and beyond, in the hopes of expanding the capacity of organizations like AABN. Methods: A survey was conducted amongst 21 Black women who were pregnant or had given birth in the last year, regarding perceptions of technology. Women were split equally into three focus groups to discuss survey results further and provide context. Focus groups were recorded, transcribed, and coded for themes. Results: Participants were likely to use their phone or the internet to look for general or health-related information, but only somewhat likely to trust either general or health-related information. Participants were somewhat likely to trust the information on the phone or the internet as much as their healthcare provider (doctor, nurse, doula) in person. In the focus groups, all participants agreed that the phone or the internet was the first place looked to for information, ahead of consulting a healthcare professional. A comprehensive list of desired features was generated to guide the development of a resource to support AABN. Conclusions: Study findings support exploring mobile technology-based approaches for breastfeeding support and education. Participants emphasized that to be relevant for them, a telehealth resource would need to: 1) Build meaningful connections between patients and providers, 2) Treat diverse opinions with trust and respect, and 3) Offer multiple sources and formats for information that can be easily cross-referenced.

Background: Coronavirus disease (COVID-19) is an infectious disease that is caused by the SARS-CoV-2virus. The objective of this study was to determine SARS COV-2 Mortality and its associated factors in East Shewa Zone Treatment centers, Oromia, Ethiopia, 2022. The study of these types of viral infection will add new insight into the most common causes of mortality in SARS-CoV-2infection and the most common co-morbidities associated with the disease in the East Shewa Zone. Methods: The study was conducted on patients who were admitted to Adama Hospital medical college and Modjo Primary Hospital for SARS-COV 2 treatment. The study period was from March 2020- Dec 2022 GC. The study population was SARS-COV 2 patients who come to Adama Hospital and Medical College and Modjo Primary Hospital for treatment. All eligible SARS-CoV-2 patients9 data were collected from Both Adama and Modjo treatment center SARS-CoV-2 accession registration book and medical record card. Result: A total of 409 patient data were collected from which 199 were from Adama Hospital and Medical College and 210 samples were collected from Modjo Primary Hospital Treatment center. The study design was a retrospective Cross-sectional study. The most affected age group in terms of mortality was the age group between 60-69 years old which suffers a 45.28% death rate. The major sign symptoms identified include cough (80.4%), Shortness of breath (66.7%) followed by fever (43.2%). SARS-CoV-2 Comorbidity was detected in 152 (37.2%) patients. Pneumonia was identified as the major comorbid disease to be recorded with 89(21.8%) cases. Other major comorbidities include Hypertension (16.9%) and Diabetes Mellites (13.9%). The least identified comorbidities were anemia (0.2%), Rectal cancer (0.2%), breast cancer (0.5%), and Chronic liver disease. Conclusion: Nearly one in four (22.7%) SARS-COV 2 patients admitted for treatment to Adama Hospital and Medical College and Modjo Primary Hospital did not make their way out of treatment Hospitals alive. Pneumonia was identified as the major comorbid disease to be recorded with 89(21.8%) cases.

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

Advances in the field of image classification using convolutional neural networks (CNNs) have greatly improved the accuracy of medical image diagnosis by radiologists. Numerous research groups have applied CNN methods to diagnose respiratory illnesses from chest x-rays, and have extended this work to prove the feasibility of rapidly diagnosing COVID-19 to high degrees of accuracy. One issue in previous research has been the use of datasets containing only a few hundred images of chest x-rays containing COVID-19, causing CNNs to overfit the image data. This leads to a lower accuracy when the model attempts to classify new images, as would be clinically expected of it. In this work, we present a model trained on the COVID-QU-Ex dataset, overall containing 33,920 chest x-ray images, with an equal share of COVID-19, Non-COVID pneumonia, and Normal images. The model itself is an ensemble of pre-trained CNNs (ResNet50, VGG19, VGG16) and GLCM textural features. It achieved a 98.34% binary classification accuracy (COVID-19/no COVID-19) on a balanced test dataset of 6581 chest x-rays, and 94.68% for distinguishing between COVID-19, Non-COVID pneumonia and normal chest x-rays. Also, we herein discuss the effects of dataset size, demonstrating that a 98.82% 3-class accuracy can be achieved using the model if the training dataset only contains a few thousand images, but that generalisability of the model suffers with such small datasets.

Introduction Ethnicity information is recorded routinely in electronic health records (EHRs); however, to date, there is no national standard or framework for harmonisation of the existing records. Methods and analysis The national ethnicity-spine uses anonymised individual-level population-scale ethnicity data from 26 EHR available through the Secure Anonymised Information Linkage (SAIL) Databank. A total of 46 million ethnicity records for 4,297,694 individuals in Wales-UK over 22 years (between 2000 and 2021) have been compiled in a harmonised, deduplicated longitudinal research ready data asset. We serialised this data and compared distribution of records over time for four selection approaches (Latest, Mode, Weighted-Mode and Composite) across age bands, sex, deprivation quintiles, health board, and residential location, against the ONS census 2011. The distribution of the dominant group (White) is minimally affected based on the four different selection approaches. Across all other ethnicity categorisations, the Mixed group was most susceptible to variation in distribution depending on the selection approach used and varied from a 0.6% prevalence across the Latest and Mode approach to a 1.1% prevalence for the Weighted-Mode, compared to the 3.1% prevalence for the Composite approach. Substantial alignment was observed with ONS census with the Latest group method (kappa= 0.68, 95% CI [0.67,0.71]) across all sub-groups. Conclusion We provides a reproducible EHR based resource enabling the investigation and evaluation of health inequalities related to ethnic groups in Wales. This generalisable method informs opportunities for the transferability of this methodology across the UK to platforms with comparable routine data sources. Ethics and dissemination This work was supported by the Con-COV team funded by Medical Research Council, Health Data Research UK, ADR Wales funded by ADR UK through the Economic and Social Research Council, and the Wales COVID-19 Evidence Centre, funded by Health and Care Research Wales.

In year one of the COVID-19 epidemic, the incidence of infection for US carceral populations was 5.5-fold higher than that in the community. Prior to the rapid roll out of a comprehensive jail surveillance program of Wastewater-Based Surveillance (WBS) and individual testing for SARS-CoV-2, we sought the perspectives of formerly incarcerated individuals regarding mitigation strategies against COVID-19 to inform acceptability of the new program. In focus groups, participants discussed barriers to their receiving COVID-19 testing and vaccination. We introduced WBS and individual nasal self-testing, then queried if wastewater testing to improve surveillance of emerging outbreaks before case numbers surged, and specimen self-collection, would be valued. The participants9 input gives insight into ways to improve the delivery of COVID-19 interventions. Hearing the voices of those with lived experiences of incarceration is critical to understanding their views on infection control strategies and supports including justice-involved individuals in decision-making processes regarding jail-based interventions.

Background Antigen lateral flow devices (LFDs) have been widely used to control SARS-CoV-2. Changes in LFD sensitivity and detection of infectious individuals during the pandemic with successive variants, vaccination, and changes in LFD use are incompletely understood. Methods Paired LFD and PCR tests were collected from asymptomatic and symptomatic participants, across multiple settings in the UK between 04-November-2020 and 21-March-2022. Multivariable logistic regression was used to analyse LFD sensitivity and specificity, adjusting for viral load, LFD manufacturer, setting, age, sex, assistance, symptoms, vaccination, and variant. National contact tracing data were used to estimate the proportion of transmitting index cases (with ≥1 PCR/LFD-positive contact) potentially detectable by LFDs over time, accounting for viral load, variant, and symptom status. Findings 4131/75,382 (5.5%) participants were PCR-positive. Sensitivity vs. PCR was 63.2% (95%CI 61.7-64.6%) and specificity 99.71% (99.66-99.74%). Increased viral load was independently associated with being LFD-positive. There was no evidence LFD sensitivity differed between Delta vs. Alpha/pre-Alpha infections, but Omicron infections were more likely to be LFD positive. Sensitivity was higher in symptomatic participants, 68.7% (66.9-70.4%) than in asymptomatic participants, 52.8% (50.1-55.4%). 79.4% (68.6-81.3%) of index cases resulting in probable onward transmission with were estimated to have been detectable using LFDs, this proportion was relatively stable over time/variants, but lower in asymptomatic vs. symptomatic cases. Interpretation LFDs remained able to detect most SARS-CoV-2 infections throughout vaccine roll-out and different variants. LFDs can potentially detect most infections that transmit to others and reduce risks. However, performance is lower in asymptomatic compared to symptomatic individuals. Funding UK Government.
