<li><strong>GlycoSHIELD: a versatile pipeline to assess glycan impact on protein structures</strong> -
<div>
More than 75% of surface and secreted proteins are modified by covalent addition of complex sugars through N- and O-glycosylation. Unlike proteins, glycans do not typically adopt specific secondary structures and remain very mobile, influencing protein dynamics and interactions with other molecules. Glycan conformational freedom impairs complete structural elucidation of glycoproteins. Computer simulations may be used to model glycan structure and dynamics. However, such simulations typically require thousands of computing hours on specialized supercomputers, thus limiting routine use. Here, we describe a reductionist method that can be implemented on personal computers to graft ensembles of realistic glycan conformers onto static protein structures in a matter of minutes. Using this open-source pipeline, we reconstructed the full glycan cover of SARS-CoV-2 Spike protein (S-protein) and a human GABAA receptor. Focusing on S-protein, we show that GlycoSHIELD recapitulates key features of extended simulations of the glycosylated protein, including epitope masking, and provides new mechanistic insights on N-glycan impact on protein structural dynamics.

<li><strong>Co-infection with SARS-COV-2 Omicron and Delta Variants Revealed by Genomic Surveillance</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
We identified the co-infection of the SARS-CoV-2 Omicron and Delta variants in two epidemiologically unrelated patients with chronic kidney disease requiring haemodialysis. Both SARS-CoV-2 variants were co-circulating locally at the time of detection. Amplicon- and probe-based sequencing using short- and long-read technologies identified and quantified Omicron and Delta subpopulations in respiratory samples from the two patients. These findings highlight the importance of genomic surveillance in vulnerable populations.

<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background: Early antiviral treatment is effective for COVID-19 but currently available agents are expensive. Favipiravir is routinely used in many countries, but efficacy is unproven. Antiviral combinations have not been systematically studied. We aimed to evaluate the effect of favipiravir, lopinavir-ritonavir or the combination of both agents on SARS-CoV-2 viral load trajectory when administered early. Methods: We conducted a Phase 2, proof of principle, randomised, placebo-controlled, 2x2 factorial, double-blind trial of outpatients with early COVID-19 (within 7 days of symptom onset) at two sites in the United Kingdom. Participants were randomised using a centralised online process to receive: favipiravir (1800mg twice daily on Day 1 followed by 400mg four times daily on Days 2-7) plus lopinavir- ritonavir (400mg/100mg twice daily on Day 1, followed by 200mg/50mg four times daily on Days 2-7); favipiravir plus lopinavir-ritonavir placebo; lopinavir-ritonavir plus favipiravir placebo; or both placebos. The primary outcome was SARS-CoV-2 viral load at Day 5, accounting for baseline viral load. ClinicalTrials.gov: NCT04499677. Findings: Between 6 October 2020 and 4 November 2021, we recruited 240 participants. For the favipiravir+lopinavir-ritonavir, favipiravir+placebo, lopinavir-ritonavir+placebo and placebo-only arms, we recruited 61, 59, 60 and 60 participants and analysed 55, 56, 55 and 58 participants respectively who provided viral load measures at Day 1 and Day</p></div></li>
</ul>
<ol start="5" type="1">
<li>In the primary analysis, the mean viral load in the favipiravir+placebo arm had decreased by 0.57 log10 (95% CI -1.21 to 0.07, p=0.08) and in the lopinavir-ritonavir+placebo arm by 0.18 log10 (95% CI -0.82 to 0.46, p=0.58) more than in the placebo arm at Day 5. There was no significant interaction between favipiravir and lopinavir-ritonavir (interaction coefficient term: 0.59 log10, 95% CI -0.32 to 1.50, p=0.20). More participants had undetectable virus at Day 5 in the favipiravir+placebo arm compared to placebo only (46.3% vs 26.9%, odds ratio (OR): 2.47, 95% CI 1.08 to 5.65; p=0.03). Adverse events were observed more frequently with lopinavir-ritonavir, mainly gastrointestinal disturbance. Favipiravir drug levels were lower in the combination arm than the favipiravir monotherapy arm. Interpretation: At the current doses, no treatment significantly reduced viral load in the primary analysis. Favipiravir requires further evaluation with consideration of dose escalation. Lopinavir-ritonavir administration was associated with lower plasma favipiravir concentrations.

<li><strong>Demographic Characteristics and Clinical Features of COVID-19 Patients Admitted in a Combined Military Hospital of Bangladesh</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background: COVID-19, one of the worst pandemics in humankinds history on December 2019. Clinical presentations of COVID-19 patients are varied and being closely similar to those of seasonal flu, its difficult to differentiate it on first presentation as COVID. Clinical scenario and demographic characteristics provide important guideline in the management of COVID. Materials and Methods: The objective of this cross-sectional study was to explore the demographic characteristics and clinical features of COVID-19 patients admitted in a Combined Military Hospital of Bangladesh. Data were collected from treatment records of patients of the CMH Bogura during the period of June 2020 to August 2020. Total 219 RT-PCR positive admitted patients were included as study population. Result: Among 219 patients, 78.6% were male and 21.5% female. Mean age of patients was 34.3 (12.2). Highest percentages (67.2%) of patients were from age group 21-40 years. 85.4% of the patients had no comorbidities, and hypertension (10.1%) was the most common comorbidity. Most (83.1%) of the admitted patients were diagnosed as mild cases. 96.4% cases were symptomatic and fever (84.5%) was the most common symptoms of COVID, followed by dry cough (46.6%), sore throat (19.6%), headache (18.3%), bodyache (17.8%), loss of appetite (15.5%), tiredness (15.5%) and anorexia (14.2%). Conclusion: This single center study revealed younger age, male predominance, less presence of comorbidites, mild cases, high proportion of symptomatic patients, and fever and cough as the most common presenting features among the admitted COVID-19 patients in CMH Bogura.

<li><strong>Workplace infection control measures and romantic activities of workers during COVID-19 pandemic: a prospective cohort study in Japan</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background: Due to the COVID-19 pandemic, non-married people are at high risk of loneliness. With social interactions restricted, it is important for non-married people to acquire a new romantic partner for their mental health and quality of life. We hypothesized that infection control efforts in the workplace influence people9s social interactions, including romantic activities. Methods: We conducted an internet-based prospective cohort study from December 2020 (baseline) to December 2021, using self-administered questionnaires. Briefly, 27,036 workers completed the questionnaires at baseline, and when followed up after one year, 18,560 (68.7%) participated. A total of 6,486 non- married individuals with no romantic relationship at baseline were included in the analysis. At baseline they were asked about the implementation of infection control measures in the workplace, and at follow-up they were asked about activities they performed with a view to romantic relationships during the period from baseline to follow-up. Results: Compared to workers in workplaces with no infection control measures, the OR associated with romance-related activities for those in workplaces with seven or more infection control measures was 1.90 (95% CI: 1.45-2.48, p&lt;0.001), and the OR associated with having a new romantic partner was 1.79 (95% CI: 1.20-2.66, p=0.004). Conclusions: Under the COVID-19 pandemic, the implementation of infection control measures in the workplace and the expressed satisfaction with those measures promoted romantic relationships among non-married, single individuals.

<li><strong>Structural risk factors for SARS-CoV-2 infection in an urban slum: Age, gender and income</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background The structural environment of urban slums, including physical, demographic and socioeconomic attributes, renders inhabitants more vulnerable to SARS-CoV-2 infection. Yet, little is known about the specific determinants that contribute to high transmission within these communities. Methods and findings We performed a serosurvey of an established cohort of 2,035 urban slum residents from the city of Salvador, Brazil between November 2020 and February 2021, following the first COVID-19 pandemic wave in the country. We identified high SARS-CoV-2 seroprevalence (46.4%, 95% confidence interval [CI] 44.3-48.6%), particularly among female residents (48.7% [95% CI 45.9-51.6%] vs. 43.2% [95% CI 39.8-46.6%] among male residents), and among children (56.5% [95% CI 52.3-60.5%] vs. 42.4% [95% CI 39.9-45.0%] among adults). In multivariable models that accounted for household-level clustering, the odds ratio for SARS-CoV-2 seropositivity among children was 1.96 (95% CI 1.42-2.72) compared to adults aged 30-44 years. Adults residing in households with children were more likely to be seropositive; this effect was particularly prominent among individuals with age 30-44 and 60 years or more. Women living below the poverty threshold (daily per capita household income &lt;$1.25) and those who were unemployed were more likely to be seropositive. Conclusions During a single wave of the COVID-19 pandemic, cumulative incidence as assessed by serology approached 50% in a Brazilian urban slum population. In contrast to observations from industrialized countries, SARS-CoV-2 incidence was highest among children, as well as women living in extreme poverty. These findings emphasize the need for targeted interventions that provide safe environments for children and mitigate the structural risks posed by crowding and poverty for the most vulnerable residents of urban slum communities.

<li><strong>Differential durability of humoral and T cell immunity after two and three BNT162b2 vaccinations in adults aged &gt;80 years</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
A third mRNA-based “booster” vaccination is the favored strategy to maintain protection against SARS-CoV-2 infection. Yet, significant waning of specific immunity within six months after 2nd vaccination, along with higher incidence of breakthrough infections associated with the time elapsed since 2nd vaccination raises concerns regarding the durability of immunity also after 3rd vaccination. We address the currently debated consequence of a third vaccination against SARS-CoV-2 for generating durable immunity especially in older adults. Specifically, we assessed virus-specific serum antibody and single cell blood T cell responses after vaccination with the mRNA vaccine BNT162b2 in more than 50 individuals older than 80 years. All old adults demonstrate a strong humoral response to 3rd vaccination which is higher and wanes slower than the response to 2nd vaccination, indicative of enhanced humoral immunity. In contrast, their respective T cell response reaches only the level obtained after 2nd vaccination, with similar waning over time and no enhancement of IFNγ production per cell. Because BNT162b2-mediated protection from the Omicron variant relies more on T cells than antibodies, our findings raise concern on the durability of protection from the Omicron variant by BNT162b2 in a population at risk.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
By November 2021, after the third SARS-CoV-2 wave in South Africa, seroprevalence was 60% (95%CrI 56%-64%) in a rural and 70% (95%CrI 56%-64%) in an urban community; highest in individuals aged 13-18 years. High seroprevalence prior to Omicron emergence may have contributed to reduced severity observed in the 4th wave.

<li><strong>Direct and indirect mortality impacts of the COVID-19 pandemic in the US, March 2020-April 2021</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Excess mortality studies provide crucial information regarding the health burden of pandemics and other large- scale events. Here, we used time series approaches to separate the direct contribution of SARS-CoV-2 infections on mortality from the indirect consequences of pandemic interventions and behavior changes in the United States. We estimated deaths occurring in excess of seasonal baselines stratified by state, age, week and cause (all causes, COVID-19 and respiratory diseases, Alzheimers disease, cancer, cerebrovascular disease, diabetes, heart disease, and external causes, including suicides, opioids, accidents) from March 1, 2020 to April 30, 2021. Our estimates of COVID-19 excess deaths were highly correlated with SARS-CoV-2 serology, lending support to our approach. Over the study period, we estimate an excess of 666,000 (95% Confidence Interval (CI) 556000, 774000) all-cause deaths, of which 90% could be attributed to the direct impact of SARS-CoV-2 infection, and 78% were reflected in official COVID-19 statistics. Mortality from all disease conditions rose during the pandemic, except for cancer. The largest direct impacts of the pandemic were seen in mortality from diabetes, Alzheimers, and heart diseases, and in age groups over 65 years. In contrast, the largest indirect consequences of the pandemic were seen in deaths from external causes, which increased by 45,300 (95% CI 30,800, 59,500) and were statistically linked to the intensity of non-pharmaceutical interventions. Within this category, increases were most pronounced in mortality from accidents and injuries, drug overdoses, and assaults and homicides, while the rate of death from suicides remained stable. Younger age groups suffered the brunt of these indirect effects. Overall, on a national scale, the largest consequences of the COVID-19 pandemic are attributable to the direct impact of SARS-CoV-2 infections; yet, the secondary impacts dominate among younger age groups, in periods of stricter interventions, and in mortality from external causes. Further research on the drivers of indirect mortality is warranted to optimize interventions in future pandemics.

<li><strong>Clinical and immunological features of SARS-CoV-2 breakthrough infections in vaccinated individuals requiring hospitalization</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
Background: Waning immunity and the surge of SARS-CoV-2 variants are responsible for breakthrough infections, i.e. infections in fully vaccinated individuals. Although the majority of vaccinated infected subjects reports mild or no symptoms, some others require hospitalization. The clinical and immunological features of vaccinated hospitalized COVID-19 patients are currently unknown. Methods: 29 unvaccinated and 36 vaccinated hospitalized COVID-19 patients were prospectively enrolled and clinical and laboratory data. Immunophenotyping of leukocytes subsets, T and B cell SARS- CoV-2 specific responses were evaluated via flow cytometry. Anti-IFN-α autoantibodies were measured via ELISA. Results: Despite vaccinated patients were older and with more comorbidities, unvaccinated subjects showed higher levels of pro- inflammatory markers, more severe disease and increased mortality rate. Accordingly, they presented significant alterations in the circulating leukocyte composition, typical of severe COVID-19. Vaccinated patients displayed higher levels of anti-Spike IgGs and Spike-specific B cells. Of all participants, survivors showed higher levels of anti-Spike IgGs and S-specific CD4+ T cells than non-survivors. At hospital admission, 6 out of 65 patients (9.2%) displayed high serum concentrations of autoantibodies targeting IFN-α. Remarkably, 3 were unvaccinated and eventually died, while the other 3 were vaccinated and survived. Conclusion: Despite more severe pre-existing clinical conditions, vaccinated patients have good outcome. A rapid activation of anti-SARS-CoV-2-specific immunity is fundamental for the resolution of the infection. Therefore, prior immunization through vaccination provides a significant contribute to prevention of disease worsening and can even overcome the presence of high-risk factors (i.e. older age, comorbidities, anti-IFN-α autoantibodies positivity).

<li><strong>Combined oropharyngeal/nares and nasopharyngeal swab sampling remain effective for molecular detection of SARS-CoV-2 Omicron variant</strong> -

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
The world has experienced several waves of SARS-CoV-2 variants of concern (VoCs) throughout the COVID-19 pandemic since the first cases in December 2019. The Omicron VoC has increased transmission, compared to its predecessors, and can present with sore throat and other cold-like symptoms. Given the predominance of throat symptoms, and previous work demonstrating better sensitivity using antigen-based rapid detection tests when a throat swab is included in the standard nasal sampling, this quality improvement project sought to ensure ongoing suitability of both combined oropharyngeal/nares (OPN) and nasopharyngeal (NP) swab sampling used throughout the pandemic. Consenting participants meeting Public Health testing criteria (mostly symptomatic or a close contact of a known case) were enrolled, and paired NP and OPN swabs collections were subjected to nucleic acid amplification testing (NAAT). Comparing paired specimens from 392 participants sensitivity of NP swabs was 89.1% (95% CI, 78.8-94.9), and that of OPN was 98.4% (95% CI: 90.9-&gt;99.9) (p-value 0.052). This project demonstrated that both NP and combined OPN swabs detected the Omicron variant with similar sensitivity by NAAT, supporting the continued use of either swab collection for SARS-CoV-2 molecular detection.

<li><strong>Predicting COVID-19 outbreak using open mobility data for minimal disruption on the countrys economy</strong> -
<div>
<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
COVID-19 is an infectious disease caused by the SARS-COV-2 coronavirus, which was discovered in late 2019. Within a few months, COVID-19 was declared a global pandemic by the WHO. Several countries adopted social distancing measures, such as self-quarantine, workplace and mobility restrictions, reducing the probability of contact between non- infected and infected people. In general, these measures have a negative impact on low-income economies and small and medium businesses. During the outbreak, several predictive models have been proposed in order to assess the level of saturation that health services might have. Nevertheless, none of them considers information on the people9s mobility to assess the effectiveness of the social distancing policies. In this study, the authors propose a prediction method based on people9s open mobility data from Apple and Google databases to project potential scenarios and monitor case growth. The proposed method shows the importance of monitoring daily case increases for the first 4-6 weeks of the pandemic wave. Active monitoring is crucial to determine the reduction in mobility and proper actions. The results can contribute to health authorities making timely decisions, preventing the spread of viruses while balancing the reduction of mobility with minimal disruption in people9s economies in future outbreaks.

Misinformation remains an important public health concern, especially as it is widely seen as a factor affecting peoples behavior during the COVID-19 pandemic. In past reports, we have discussed the prevalence and demographics of COVID-19 misinformation, its link to vaccination rates, and its dependence on social media news consumption. Here, we examine the over-time shifts in COVID-19 vaccine misperceptions across different social groups. We explore whether those who believe misinformation are aware that their views contradict the prevailing opinion of scientists and medical experts. We highlight the connection between COVID-19 misinformation and trust in the government, media, science and medicine. Finally, we update our findings linking misperceptions with attitudes towards the COVID-19 vaccine.

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.

One thing to keep in mind is that there is a segment of the population that has been exposed to the covid-19 virus and has generated antibodies without developing any significant illnesses and is continuing to be healthy. This indicates that a significant section of the population, even excluding the elderly, lacks the necessary bodily immunity to combat a Viral infection. As terrible as covid-19 is on a global scale, developing personal health standards and preventative measures for any pathogenic virus as a community would have spared many lives. Inthis work, a camera is combined with an image processing system to recognise facial masks, which may be improved in a variety of ways. First and foremost, this method is meant to identify masks on a single persons face. While this method is efficient in identifying someone has a mask, it does not ensure that they will wear it all of the time. The most effective update for this task is to install a camera with a wide field of view so that many individuals can be seen in the frame, and the faces of those who arent wearing markings can be identified, as well as the number of people and the timing. - <a href="https://patentscope.wipo.int/search/en/detail.jsf?docId=IN346889253">link</a></p></li>
