<li><strong>Exploring Trauma Responsive Educational Practices in a Museum</strong> -

<div>

Trauma infiltrates all of society – including museums. For guests, the trauma may lie in the context of the visit or what they bring with them from their everyday lives. Staff can develop trauma through daily interaction with stressful content or secondary trauma through interaction with traumatized guests. During the COVID19 pandemic, trauma also developed from workplace issues regarding personal health safety and job security. This is a case study about how one museum educated itself about the presence and impact of trauma through exploration of a framework developed by the Trauma Responsive Educational Practices (TREP) Project. We present results of a staff-wide evaluation around initial implementation of the framework. Results show staff found the framework to be relevant and useful, but they need more support adapting it to the unique environment of museums. It also triggered memories of personal trauma in some staff, requiring a rethinking about how to implement it.

A correlation hypothesis between the level of vaccination and the rate of spread of the new Covid-19 variant is investigated based on the case and vaccination data from European and North American jurisdictions available in the public domain at the time point of past the crest of the Omicron wave in most jurisdictions. Statistical variables describing the rate of the spread based on observed new case statistics defined and discussed. An unexpected moderate positive correlation between the rate of the variant spread measured by two related parameters and vaccination level based on the dataset in the study is reported. While negative correlation was not statistically excluded, the analysis of the data in the study statistically excluded a moderate to strong negative correlation. The results of this work, if confirmed by further independent studies can have implications for development of policies aimed at controlling future course of the Covid-19 pandemic.

Background: Immunization stress-related responses presenting as stroke-like symptoms may develop following COVID-19 vaccination. This study aimed to describe the clinical characteristics of immunization stress-related responses causing stroke-like events following COVID-19 vaccination. Methods: We conducted a retrospective study of the secondary data of reported adverse events following COVID-19 immunization that presented with neurologic manifestations. Between March 1 and July 31, 2021, we collected and analyzed the medical records of 221 patients diagnosed with stroke-like symptoms following immunization. Demographic and medical data included sex, age, vaccine type, sequence dose, time to event, laboratory data, and recovery status as defined by the modified Rankin score (i.e., defining the degree of severity/dependence, with higher scores indicating greater disability). The affected side was evaluated for associations with the injection site. Results: In total, 221 patients were diagnosed with immunization stress-related responses (stroke-like symptoms) following CoronaVac (Sinovac) or ChAdOx1 (AstraZeneca) vaccinations. Most patients (83.7%) were women. The median (interquartile range) age of onset was 34 (28–42) years in patients receiving CoronaVac and 46 (33.5–60) years in those receiving ChAdOx1. The median interval between vaccination and symptom onset for each vaccine type was 60 (16–960) min and 30 (8.8–750) min, respectively. Sensory symptoms were the most common symptomology. Most patients (53.8%) developed symptoms on the left side of the body; 99.5% of the patients receiving CoronaVac and 90% of those receiving ChAdOx1 recovered well (modified Rankin scores <=2, indicating slight or no disability). Conclusions: Immunization stress-related responses presenting as stroke-like symptoms can develop following COVID-19 vaccination. Symptoms that are more likely to occur on the injection side are transient (i.e., without permanent pathological deficits). Public education and preparedness are important for administering successful COVID-19 vaccination programs.

Aim: To estimate the length of stay distributions of hospitalised COVID-19 cases during a mixed Omicron-Delta epidemic in New South Wales, Australia (16 Dec 2021 – 7 Feb 2022), and compare these to estimates produced over a Delta-only epidemic in the same population (1 Jul 2021 – 15 Dec 2022). Background: The distribution of the duration that clinical cases of COVID-19 occupy hospital beds (the `length of stay9) is a key factor in determining how incident caseloads translate into health system burden as measured through ward and ICU occupancy. Results: Using data on the hospital stays of 19,574 individuals, we performed a competing-risk survival analysis of COVID-19 clinical progression. During the mixed Omicron-Delta epidemic, we found that the mean length of stay for individuals who were discharged directly from ward without an ICU stay was, for age groups 0-39, 40-69 and 70+ respectively, 2.16 (95% CI: 2.12–2.21), 3.93 (95% CI: 3.78–4.07) and 7.61 days (95% CI: 7.31–8.01), compared to 3.60 (95% CI: 3.48–3.81), 5.78 (95% CI: 5.59–5.99) and 12.31 days (95% CI: 11.75–12.95) across the preceding Delta epidemic (15 Jul 2021 – 15 Dec 2021). We also considered data on the stays of individuals within the Hunter New England Local Health District, where it was reported that Omicron was the only circulating variant, and found mean ward-to-discharge length of stays of 2.05 (95% CI: 1.80–2.30), 2.92 (95% CI: 2.50–3.67) and 6.02 days (95% CI: 4.91–7.01) for the same age groups.

While the combination of casirivimab –imdevimab (Ronapreve™ Roche Regeneron) has been shown to confer satisfactory protection against the delta variant kidney transplant recipients (KTRs) with COVID –19, it has limited neutralizing activity against the current variants of concern (Omicron BA.1 , BA.1.1 and BA.2). In contrast, cilgavimab –tixagevimab combination (Evusheld™, Astra Zeneca) retains a partial neutralizing activity against omicron in vitro. We examined whether preexposure prophylaxis with Evusheld™ can effectively protect kidney transplant recipients (KTRs) against the Omicron variant. Of the 416 KTRs who received intramuscular prophylactic injections of Evusheld™ (150 mg tixagevimab and 150 mg cilgavimab), 39 (9.4%) developed COVID-19. With the exception of one patient, all KTRs were symptomatic. Hospitalization and admission to an intensive care unit were required for 14 (35.9%) and three patients, respectively. Two KTRs died of COVID-19-related acute respiratory distress syndrome. SARS-CoV-2 sequencing was carried out in 15 cases (BA.1, n = 5; BA.1.1, n = 9; BA.2, n=1). Viral neutralizing activity of the serum against BA.1 variant was negative in the 12 tested patients, suggesting that this prophylaxis strategy provides insufficient protection against this variant of concern . Preexposure prophylaxis with Evusheld™ does not adequately protect KTRs against Omicron. Further clarification of the optimal dosing can assist in our understanding of how best to harness its protective potential.

<li><strong>Pre-exposure to mRNA-LNPs reprograms adaptive and innate immune responses in an inheritable fashion</strong> -
|
||
<div>
|
||
Billions of SARS-CoV-2 mRNA-LNP vaccine doses have already been administered to humans. However, we lack a comprehensive understanding of the immune effects of this platform. Here we bring experimental evidence that pre- exposure to mRNA-LNPs or its LNP component has effects on both innate and adaptive immune responses. Pre-exposure to mRNA-LNPs led to long-term, platform-specific inhibition of the adaptive immune responses. As such, mice responded with lower antibody responses when exposed the second time to the mRNA-LNP platform, but with undisturbed adaptive immune responses to protein-based Alum or AddaVax-adjuvanted vaccines. On the other hand, we report that after pre-exposure to mRNA-LNPs, resistance of mice to heterologous infections with influenza virus and Candida albicans is likely enhanced. Interestingly, mice pre-exposed to mRNA-LNPs can pass down the acquired immune traits to their offspring, providing better protection. In summary, the mRNA-LNP vaccine platform induces long-term immunological changes that can affect both humoral responses and heterologous protection against infections. More studies are needed to understand in-depth the mechanisms responsible for these effects.

<li><strong>COVID-19 patients have increased levels of membrane-associated and soluble CD48</strong> -
|
||
<div>
|
||
COVID-19 is a respiratory-centered systemic disorder caused by SARS-CoV-2. The disease can progress into a severe form causing acute lung injury. CD48 is a co-signaling receptor, existing as both membrane-bound and soluble forms reported to be dysregulated in several inflammatory conditions. Therefore, we reasoned that CD48 could be deregulated in COVID-19 as well. Here we analyzed CD48 expression in autoptic sections and peripheral blood leukocytes and sera of COVID-19 patients by gene expression profiling (HTG autoimmune panel), immunohistochemistry, flow cytometry and ELISA. Lung tissue of COVID-19 patients showed increased CD48 mRNA expression and infiltration of CD48+ lymphocytes. In the peripheral blood, mCD48 was considerably increased on all evaluated cells, and additionally, sCD48 levels were significantly higher in COVID-19 patients independently of disease severity. Considering the alterations of mCD48 and sCD48, a specific role for CD48 in COVID-19 can be assumed, suggesting it as a potential target for therapy.

This article contributes to the mixed-methods research (MMR) field a description of utilizing MMR in a single- subject design. The example utilizes a convergent intensive longitudinal data collection strategy and an explanatory bidirectional framework for data merging analytics to examine one faculty member’s practices of incorporating social- emotional learning (SEL) and mindfulness during the COVID-19 pandemic in an effort to reduce burnout. By examining results from the dynamic p-technique (a special case of structural equation modeling) and reflexive journaling resulting in autoethnography, a clearer picture of one faculty member’s lived experience emerged. The study is a concrete demonstration of how structural equation modeling and autoethnography methods can be combined within a convergent explanatory bidirectional analytic framework following a single subject through time. Readers interested in replicating the dynamic p-technique analyses can access our tutorial and supplemental materials at https://bit.ly/osfburnout.

With the emergence of Artificial Intelligence (AI), new attention has been given to implement AI algorithms on resource constrained tiny devices to expand the application domain of IoT. Multimodal Learning has recently become very popular with the classification task due to its impressive performance for both image and audio event classification. This paper presents - a flexible system algorithm co-designed multimodal learning framework for resource constrained tiny devices. The framework was designed to be evaluated on two different case-studies: COVID-19 detection from multimodal audio recordings and battle field object detection from multimodal images and audios. In order to compress the model to implement on tiny devices, substantial network architecture optimization and mixed precision quantization were performed (mixed 8-bit and 4-bit). shows that even a tiny multimodal learning model can improve the classification performance than that of any unimodal frameworks. The most compressed achieves 88.4% COVID-19 detection accuracy (14.5% improvement from unimodal base model) and 96.8% battle field object detection accuracy (3.9% improvement from unimodal base model). Finally, we test our models on a Raspberry Pi 4 to see how they perform when deployed to a resource constrained tiny device.

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

BACKGROUND: Protection conferred by natural SARS-CoV-2 infection versus COVID-19 vaccination has not been investigated in rigorously controlled studies. We compared head-to-head protection conferred by natural infection to that from the BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) vaccines in Qatar, between February 28, 2020 and March 6, 2022. METHODS: Two national matched retrospective target-trial cohort studies were conducted to compare incidence of SARS-CoV-2 infection and COVID-19 hospitalization and death among those with a documented primary infection to incidence among those with a two-dose primary-series vaccination. Associations were estimated using Cox proportional-hazards regression models. RESULTS: The overall adjusted hazard ratio (AHR) for infection was 0.46 (95% CI: 0.45-0.48) comparing those with a prior infection to those vaccinated with BNT162b2, and 0.51 (95% CI: 0.48-0.53) comparing those with a prior infection to those vaccinated with mRNA-1273. For BNT162b2, the AHR decreased gradually from 0.55 (95% CI: 0.46-0.65) in the fourth month after primary infection/vaccination to 0.31 (95% CI: 0.27-0.37) in the eighth month, while for mRNA-1273, it decreased from 0.80 (95% CI: 0.59-1.07) to 0.35 (95% CI: 0.29-0.41) over the same time period. During the Omicron wave, the AHR was ~0.50 for BNT162b2 and ~0.60 for mRNA-1273. The overall AHR for any severe, critical, or fatal COVID-19 (against all variants) was 0.32 (95% CI: 0.10-1.00) for BNT162b2, and 0.58 (95% CI: 0.14-2.43) for mRNA-1273. CONCLUSIONS: Natural infection was associated with stronger and more durable protection against infection, regardless of the variant, than mRNA primary-series vaccination. Nonetheless, vaccination remains the safest and optimal tool of protection against infection and COVID-19 hospitalization and death.

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

Immunity to SARS-CoV-2 following vaccination wanes over time in a non-linear fashion, making modelling of likely population impacts of COVID-19 policy options challenging. We observed that it was possible to mathematize non-linear waning of vaccine effectiveness (VE) on the percentage scale as linear waning on the log-odds scale, and developed a random effects logistic regression equation based on UK Health Security Agency data to model VE against Omicron following two and three doses of a COVID-19 vaccine. VE on the odds scale reduced by 47% per month for symptomatic infection after two vaccine doses, lessening to 35% per month for hospitalisation. Waning on the odds scale after triple dose vaccines was 35% per month for symptomatic disease and 19% for hospitalisation. This log-odds system for estimating waning and boosting of COVID-19 VE provides a simple solution that may be used to parametrize SARS-CoV-2 immunity over time parsimoniously in epidemiological models.

<ol start="2021" type="1">

<li>Here we examined 2,323 virus genomes from Alaska and 278,635 virus genomes from the contiguous United States collected between the first week of December 2020 through the last week of June 2021. We focused on this timeframe because of the notable emergence and spread of the SARS-CoV-2 lineage B.1.1.519 observed in Alaska. We found that this variant was consistently detected in Alaska from the end of January through June of 2021 with a peak prevalence in April of 77.9% unlike the rest of the United States with a peak prevalence of 4.6%. In Alaska, the earlier emergence of B.1.1.519 coincided with a later peak of Alpha (B.1.1.7) when compared to the rest of the United States. We also observed differences in the composition of lineages and variants over time between the two most populated regions of Alaska. Although there was a modest increase in COVID-19 cases during the peak incidence of B.1.1.519, it is difficult to disentangle how social dynamics conflated changes in COVID-19 during this time. We suggest that the viral characteristics, such as amino acid substitutions in the spike protein, and a founder effect likely contributed to the unique spread of B.1.1.519 in Alaska.

Dysregulated host responses to infection can lead to organ dysfunction and sepsis, causing millions of deaths globally each year. To alleviate this burden, improved prognostication and biomarkers of response are urgently needed. We investigated the use of whole blood transcriptomics for stratification of patients with severe infection by integrating data from 3,149 samples of sepsis patients and healthy individuals into a gene expression reference map. We used this map to derive a quantitative sepsis response signature (SRSq) score reflective of immune dysfunction and predictive of clinical outcomes, which can be estimated using a 19-gene signature. Finally, we built a machine learning framework, SepstratifieR, to deploy SRSq in sepsis, H1N1 influenza, and COVID-19, demonstrating clinically relevant stratification across diseases and revealing the physiological alterations linking immune dysregulation to mortality. Our method enables early identification of individuals with dysfunctional immune profiles, thus bringing us closer to precision medicine in infection.

Since the COVID has stopped the Industries/Companies to conduct campus interview and direct recruitment throughout India. This leads to huge unemployment and companies lack in finding the correct person for their job. To overcome this issue it is proposed to develop an application where recruiters can easily conduct their recruitment process. This app integrates the student’s database and the Industry/company database. This model helps the recruiter to choose the eligible student from the huge database instead of a group of students from a particular University/college. There are many benefits like faster recruitment process, many students finding their dream job, HR process the interview from the remote location, entire process is in online, no need to travel and accommodate a place for rent. The entire process is recorded and saved as a report, this ensures 100 % genuine and no space for malpractice. - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN352549250">link</a></p></li>

<li><p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom"><strong>SOCIAL NAVIGATION SYSTEM FOR MOBILE ROBOTS IN THE EMERGENCY DEPARTMENT TECHNOLOGY</strong> - The emergency department (ED) is a safety-critical environment in which healthcare workers (HCWs) are overburdened, overworked, and have limited resources, especially during the COVID-19 pandemic. One way to address this problem is to explore the use of robots that can support clinical teams, e.g., to deliver materials or restock supplies. However, due to EDs being overcrowded, and the cognitive overload HCWs experience, robots need to understand various levels of patient acuity so they avoid disrupting care delivery. In this invention, we introduce the Safety-Critical Deep Q-Network (SafeDQN) system, a new acuity-aware navigation system for mobile robots. SafeDQN is based on two insights about care in EDs: high-acuity patients tend to have more HCWs in attendance and those HCWs tend to move more quickly. We compared SafeDQN to three classic navigation methods, and show that it generates the safest, quickest path for mobile robots when navigating in a simulated ED environment. We hope this work encourages future exploration of social robots that work in safety-critical, human-centered environments, and ultimately help to improve patient outcomes and save lives.
