<li><strong>TinyM2Net: A Flexible System Algorithm Co-designed Multimodal Learning Framework for Tiny Devices</strong> -
<div>
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.

<li><strong>Protection of prior natural infection compared to mRNA vaccination against SARS-CoV-2 infection and severe COVID-19 in Qatar</strong> -
<div>
<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.

<li><strong>A log-odds system for waning and boosting of COVID-19 vaccine effectiveness</strong> -
<div>
<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.

</ul>
<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.

<li><strong>An immune dysfunction score for stratification of patients with acute infection based on whole blood gene expression</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
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.

<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background and aim : Despite the significant mental health challenges the COVID-19 pandemic and its associated government measures have presented, research have shown that the majority of people have adapted and coped well. The aim of this study was i) to determine the proportion of people with mental stability and volatility during the pandemic in a North West urban environment sample and ii) to establish group differences in psychosocial variables. Mental stability and volatility refer to the extent to which individuals reported change in levels of common mental health symptoms over the course of 12 weeks. Method : a two-wave-online survey (N = 163) was used to explore the psychological and social impact of the pandemic on relatively disadvantaged neighbourhoods within the Liverpool City Region over 12 weeks. Kruskal-Wallis with post-hoc tests were used to determine how people with mental stability and volatility differed on factors categorised within an ecological framework of resilience (individual, community, societal, and COVID-19 specific). Results : Individuals categorised as stable in terms of mental health symptoms (63.6%) had better mental and physical health; were more tolerant of uncertainty; reported higher levels of resilience and wellbeing compared to very volatile people (19.8%). These individuals also reported feeling less socially isolated, experienced a greater sense of belonging to their community which was more likely to fulfil their needs, and were more likely to have access to green space nearby for their recommended daily exercise. Stable individuals did not report worrying any more during the pandemic than usual and tolerated uncertainty better compared to those in the volatile group. Implications : The majority of participants in this sample were mentally stable and coping well with the challenges presented by the pandemic. The resilience of these individuals was related to key place-based factors such as a strong sense of community and useable local assets. The data showcase the role of place-based social determinants in supporting resilience and thereby highlight key preventative measures for public mental health during times of international crisis.

<li><strong>Effectiveness of whole virus COVID-19 vaccine at protecting health care personnel against SARS-CoV-2 infections in Lima, Peru</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
In February 2021, Peru launched a vaccination campaign among healthcare personnel using BBIBP-CorV inactivated whole virus (BBIBP-CorV) COVID-19 vaccine. Two doses of BBIBP-CorV vaccine are recommended, 21 days apart. Data on BBIBP-CorV vaccine effectiveness will inform the use and acceptance of vaccination with BBIBP-CorV vaccine. We evaluated BBIBP-CorV vaccine effectiveness among an existing multi-year influenza cohort at two hospitals in Lima. We analyzed data on 290 participants followed between February and May 2021. Participants completed a baseline questionnaire and provided weekly self-collected anterior nasal swabs tested for SARS-CoV-2 by rRT-PCR for sixteen weeks. We performed multivariable logistic regression models adjusting for pre-selected characteristics (age, sex, exposure to COVID-19 patients, work in intensive care unit or emergency department, BMI, and exposure time in days). BBIBP-CorV vaccine effectiveness was calculated after the two-week post-vaccination period as (1-Odds Ratio for testing SARS-CoV-2 positive)x100%. SARS-CoV-2 was detected by rRT-PCR among 25 (9%) participants during follow-up (February-May 2021). Follow-up period ranged 1-11 weeks (median: 2 weeks). Among cohort participants who were fully vaccinated the adjusted vaccine effectiveness against SARS-CoV-2 infection was estimated as 95% (95% CI: 70%, 99%) and 100% (95% CI: 88%, 100%) for those partially vaccinated. During the study period, vaccination of healthcare personnel with BBIBP-CorV vaccine was effective at reducing SARS-CoV-2 infections in the weeks immediately following vaccination. This information can be used to support vaccination efforts in the region, especially among those who could be concerned about their effectiveness.

<li><strong>Patient-reported respiratory outcome measures in the recovery of adults hospitalised with COVID-19: A systematic review and meta-analysis</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background Acute COVID-19 clinical symptoms have been clearly documented, but long-term functional and symptomatic recovery from COVID -19 is less well described. Methods A systematic review and meta-analysis were conducted to describe patient-reported outcome measures (PROMs) in adults at least 8 weeks post hospital discharge for COVID-19. Comprehensive database searches in accordance with the PRISMA statement were carried out up till 31/05/2021. Data were narratively synthesized, and a series of meta-analyses were performed using the random-effects inverse variance method. Results From 49 studies, across 14 countries with between 2-12 months follow up, the most common persisting symptom reported was fatigue with meta-analysis finding 36.6% (95 % CI 27.6 to 46.6, n=14) reporting it at 2-4 months, decreasing slightly to 32.5% still reporting it at &gt;4 months (95% CI 22.6 to 44.2, n=15). This was followed by dyspnoea. Modified MRC score (mMRC) ≥1 was reported in 48% (95% CI 30 to 37, n=5) at 2-4months reducing to 32% (95% CI 22 to 43, n=7) at 4 months. Quality of life (QOL) as assessed by the EQ-5D-5L VAS remained reduced at &gt;4 months (73.6 95% CI 68.1 to 79.1, n=6). Hospitalisation with COVID-19 also resulted in persisting sick leave, change in scope of work, and continued use of primary and secondary healthcare. Conclusion The symptomatic and functional impact of COVID-19 continues to be felt by patients months after discharge from hospital. This widespread morbidity points towards a multi-disciplinary approach to aid functional recovery.

<li><strong>Mobility was a Significant Determinant of Reported COVID-19 Incidence During the Omicron Surge in the Most Populous U.S. Counties</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
We studied the relationship between declines in mobility and subsequently reported COVID-19 case incidence in 111 of the most populous U.S. counties during the Omicron surge from December 2021 through February 2022. We employed principal component analysis to construct a one-dimensional summary measure of the six Google mobility categories that are regularly reported for each county. Among counties with a lower mobility decline between December 20 and January 3, reported COVID-19 incidence did not peak until the week ending January 17, whereas among counties with a higher mobility decline, incidence peaked earlier by the week ending January 10 and remained significantly lower. Based upon a fixed- effects, longitudinal cohort model, we estimated that every 1-percent decline in mobility between December 20 and January 3 was associated with a 0.63 percent decline in peak incidence during the week ending January 17 (95% confidence interval, 0.40-0.86 percent). Based upon a cross-sectional analysis including mean household size and vaccination participation as covariates, we estimated that the same 1-percent decline in mobility was associated with a 0.36 percent decline in cumulative reported COVID-19 incidence from January 10 through February 28 (95% CI, 0.18-0.54 percent). Omicron did not simply sweep through the U.S. population until it ran out of susceptible individuals to infect. To the contrary, a significant fraction managed to avoid infection by engaging in risk-mitigating behaviors. More broadly, the behavioral response to perceived risk should be viewed as an intrinsic component of the natural course of epidemics in humans.

<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Selection of reference genes in quantitative PCR is critical to determine accurate and reliable mRNA expression. Despite this knowledge, not a single study has investigated the expression stability of housekeeping genes to determine their suitability to act as reference gene in SARS-CoV-2 or Covid19 associated mucormycosis (CAM) infections. Herein, we address these gaps by investigating the expression stability of nine most commonly used housekeeping genes including TBP, CypA, B2M, 18S, PGC-1α, GUSB, HPRT-1, β-ACTIN and GAPDH in the patients of varying severity (asymptomatic, mild, moderate and severe). We observed significant differences in the expression of candidate genes across the disease spectrum. Next, using various statistical algorithms (delta Ct, Normfinder, Bestkeeper, RefFinder and GeNorm), we observed that CypA demonstrated the most consistent expression across the patients of varying severity and emerged as the most suitable gene in Covid19, and CAM infections. Incidentally, the most commonly used reference gene GAPDH showed maximum variations and found to be the least suitable. Lastly, comparative evaluation of expression of NRF2 is performed following normalization with GAPDH and CypA to highlight the relevance of an appropriate reference gene. Our results reinforce the idea of a selection of housekeeping genes only after validation especially during infections.

<li><strong>Survey of nationwide public perceptions regarding acceptance of wastewater used for community health monitoring in the United States</strong> -

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
During the coronavirus disease 2019 (COVID-19) pandemic researchers looked for evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in feces dissolved in wastewater samples to assess levels of infection across communities. This activity is known colloquially as sewer monitoring and called wastewater-based epidemiology in academic settings. When used for public health surveillance in the United States, wastewater monitoring is not regulated, although general ethical principles have been described. Prior to this study, no nationwide data existed regarding the public9s perceptions of wastewater being used for community health monitoring. Using an online survey distributed to a representative sample of adults in the Unites States (N=3,083), we investigated the public9s perceptions regarding what is monitored, where monitoring occurs, and privacy concerns related to wastewater monitoring as a public health surveillance tool. Further, the Privacy Attitudes Questionnaire assessed respondents9 general privacy boundaries. The results suggest that respondents supported using wastewater for health monitoring, but within some bounds. Participants were most likely to support or strongly support monitoring for disease (95%), environmental toxins (94%), and terroristic threats (90%, e.g., anthrax). Two-thirds of respondents endorsed no prohibition to locations being monitored while the most common category of location respondents wanted to be prohibited from monitoring was personal residencies. Additionally, the findings suggest that those younger in age and living in an urban area were more supportive of wastewater monitoring, compared to older, suburban dwellers.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
At the end of 2019 a new coronavirus (called SARS-COV-2) epidemic appears in china and spreads from China to the rest of the world at beginning of 2020 and caused a new disease called COVID-19. It9s well known that, COVID-19 disease spreads between humans through the air by coughing and sneezing or by contact. In this paper, we develop a mathematical SIR model which takes into account the effect of disease transmission by coughing and sneezing and the period of latency which is represented by time delays. We prove that, there is non effect of latency period on the dynamics of the propagation and transmission of the coronavirus, and for some critical value of the basic reproduction number a transcritical bifurcation may occur and the disease disappears for values smaller than this critical value and persist otherwise. In the end, we carry out some numerical simulations in order to illustrate our theoretical results. Our study confirm that, cleaning surfaces and wearing masks is a controlling strategy for limiting the propagation of COVID-19.

Ct values varied over the course of infection, across RT-PCR platforms, and by participant age. Specimens collected from children and adolescents showed higher Ct values and adults aged ≥50 years showed lower Ct values than adults aged 18-49 years.

<li><strong>Large-scale analysis of SARS-CoV-2 synonymous mutations reveals the adaptation to the human codon usage during the virus evolution</strong> -
<div>
Many large national and transnational studies have been dedicated to the analysis of SARS-CoV-2 genome, most of which focused on missense and nonsense mutations. However, approximately 30% of the SARS-CoV-2 variants are synonymous, therefore changing the target codon without affecting the corresponding protein sequence. By performing a large-scale analysis of sequencing data generated from almost 400,000 SARS-CoV-2 samples, we show that silent mutations increasing the similarity of viral codons to the human ones tend to fixate in the viral genome over-time. This indicates that SARS- CoV-2 codon usage is adapting to the human host, likely improving its effectiveness in using the human aminoacyl-tRNA set through the accumulation of deceitfully neutral silent mutations.

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 students 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>

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.
