To characterize the epidemiological properties of the B.1.526 SARS-CoV-2 variant of interest, here we utilized nine epidemiological and population datasets and model-inference methods to reconstruct SARS-CoV-2 transmission dynamics in New York City, where B.1.526 emerged. We estimated that B.1.526 had a moderate increase (15-25%) in transmissibility and could escape immunity in 0-10% of previously infected individuals. In addition, B.1.526 substantially increased the infection-fatality risk (IFR) among adults 65 or older by >60% during Nov 2020 - Apr 2021, compared to baseline risk estimated for preexisting variants. Overall, findings suggest that new variants like B.1.526 likely spread in the population weeks prior to detection and that partial immune escape (e.g., resistance to therapeutic antibodies) could offset prior medical advances and increase IFR. Early preparedness for and close monitoring of SARS-CoV-2 variants, their epidemiological characteristics, and disease severity are thus crucial to COVID-19 response as it remains a global public health threat.
Objectives. Our objectives were (1) to evaluate the prevalence of menstrual changes following vaccination against COVID-19, (2) to test potential risk factors for any such changes, and (3) to identify patterns of symptoms in participants9 written accounts. Design. A secondary analysis of a retrospective online survey titled The Covid-19 Pandemic and Women9s Reproductive Health , conducted in March 2021 in the UK before widespread media attention regarding potential impacts of SARS-CoV-2 vaccination on menstruation. Setting. Participants were recruited via a Facebook ad campaign in the UK. Participants. Eligibility criteria for survey completion were age greater than 18 years, having ever menstruated and currently living in the UK. In total, 26,710 people gave consent and completed the survey. For this analysis we selected 4,989 participants who were pre-menopausal and vaccinated. These participants were aged 28 to 43, predominantly from England (81%), of white background (95%) and not using hormonal contraception (58%). Main outcome measure. Reports of any menstrual changes (yes/no) following COVID-19 vaccination and words used to describe menstrual changes. Results. Among pre-menopausal vaccinated individuals (n=4,989), 80% did not report any menstrual cycle changes up to 4 months after their first COVID-19 vaccine injection. Current use of combined oral contraceptives was associated with lower odds of reporting any changes by 48% (OR = 0.52, 95CI = [0.34 to 0.78], P<0.001). Odds of reporting any menstrual changes were increased by 44% for current smokers (OR = 1.16, 95CI = [1.06 to 1.26], P<0.01) and by more than 50% for individuals with a positive COVID status [Long Covid (OR = 1.61, 95CI = [1.28 to 2.02], P<0.001), acute COVID (OR = 1.54, 95CI = [1.27 to 1.86], P<0.001)]. The effects remain after adjusting for self-reported magnitude of menstrual cycle changes over the year preceding the survey. Written accounts report diverse symptoms; the most common words include 9cramps9, 9late9, 9early9, 9spotting9, 9heavy9 and 9irregular9, with a low level of clustering among them. Conclusions. Following vaccination for COVID-19, menstrual disturbance occurred in 20% of individuals in a UK sample. Out of 33 variables investigated, smoking and a previous history of SARS-CoV-2 infection are found to be risk factors while using oestradiol-containing contraceptives was found to be a protective factor. Diverse experiences were reported, from menstrual bleeding cessation to heavy menstrual bleeding.
Objectives. SARS-CoV-2 infection causes most cases of severe illness and fatality in older age groups. In China, over 99% of individuals aged ≥12 years have been fully vaccinated against COVID-19 (albeit with vaccines developed against historical lineages), while 65.0% children aged 3-11 years have been vaccinated their first doses (as of November 12, 2021). Here, we aimed to assess whether, in this vaccination landscape, the importation of Delta variant infections could shift the COVID-19 burden from adults to children. Methods. We developed an age-structured susceptible- infectious-removed model of SARS-CoV-2 transmission dynamics to simulate epidemics triggered by the importation of Delta variant infections and project the age-specific incidence of SARS-CoV-2 infections, cases, hospitalisations, intensive care unit (ICU) admissions, and deaths. Results. In the context of the vaccination programme targeting individuals aged ≥12 years (as it was the case until mid-October 2021), and in the absence of non-pharmaceutical interventions, the importation of Delta variant infections could have led to widespread transmission and substantial disease burden in mainland China, even with vaccination coverage as high as 97% across the eligible age groups. Extending the vaccination roll-out to include children aged 3-11 years (as it was the case since the end of October 2021) is estimated to dramatically decrease the burden of symptomatic infections and hospitalisations within this age group (54% and 81%, respectively, when considering a vaccination coverage of 99%), but would have a low impact on protecting infants (aged 0-2 years). Conclusions. Our findings highlight the importance of including children among the target population and the need to strengthen vaccination efforts by increasing vaccine effectiveness.
The test-trace-isolate-quarantine (TTIQ) strategy, where confirmed-positive pathogen carriers are isolated from the community and their recent close contacts are identified and pre-emptively quarantined, is used to break chains of transmission during a disease outbreak. The protocol is frequently followed after an individual presents with disease symptoms, at which point they will be tested for the pathogen. This TTIQ strategy, along with hygiene and social distancing measures, make up the non-pharmaceutical interventions that are utilised to suppress the ongoing COVID-19 pandemic. Here we develop a tractable mathematical model of disease transmission and the TTIQ intervention to quantify how the probability of detecting and isolating a case following symptom onset, the fraction of contacts that are identified and quarantined, and the delays inherent to these processes impact epidemic growth. In the model, the timing of disease transmission and symptom onset, as well as the frequency of asymptomatic cases, is based on empirical distributions of SARS-CoV-2 infection dynamics, while the isolation of confirmed cases and quarantine of their contacts is implemented by truncating their respective infectious periods. We find that a successful TTIQ strategy requires intensive testing: the majority of transmission is prevented by isolating symptomatic individuals and doing so in a short amount of time. Despite the lesser impact, additional contact tracing and quarantine increases the parameter space in which an epidemic is controllable and is necessary to control epidemics with a high reproductive number. TTIQ could remain an important intervention for the foreseeable future of the COVID-19 pandemic due to slow vaccine rollout and highly-transmissible variants with the potential for vaccine escape. Our results can be used to assess how TTIQ can be improved and optimised, and the methodology represents an improvement over previous quantification methods that is applicable to future epidemic scenarios.
Objective: To study the effect of methotrexate (MTX) and its discontinuation on the humoral immune response after COVID-19 vaccination in patients with autoimmune rheumatic diseases (AIRD). Methods: Neutralising SARS-CoV-2 antibodies were measured after second vaccination in 64 rheumatic patients on methotrexate therapy, 31 of whom temporarily paused medication without a fixed regimen. The control group consisted of 21 AIRD patients without immunosuppressive medication. Results: MTX patients showed a significantly lower median antibody response compared to AIRD patients without immunosuppressive therapy (p< 0.001). Young age (<60 years) and MTX-hold after vaccination were found to be the main factors influencing antibody response after vaccination, while BMI or MTX dose demonstrated no effect. For patients taking MTX, age correlated negatively with immune response (r=-0.49; p<0.001) and all patients with antibody levels (14 %) below the cut-off were older than 60 years. Patients who held MTX during at least one vaccination showed significantly higher median neutralising antibody levels after second vaccination, compared to patients who continued MTX therapy during both vaccinations (68.82 %, 92.73 %, p=<0.001). This effect was particularly pronounced in patients older than 60 years (p=0.0016). The impact of the time period after vaccination was greater than of the time before vaccination with the critical cut-off being 10 days. Conclusion: MTX reduces the immunogenicity of SARS-CoV-2 vaccination in an age-dependent manner. Our data further suggest that holding MTX for at least 10 days after vaccination significantly improves the antibody response in patients over 60 years of age.
Objectives: To develop new methods to address problems associated with use of traditional measures of disease surveillance, including prevalence and positivity rates. Methods: We use data from the public New York Times Github repository to develop a space-time classification index of COVID-19 hotspots. The Local Indicator of Spatial Association (LISA) statistic is applied to identify daily clusters of COVID-19 cases, from July 4th to July 19th. Results: The classification index is a spatial and temporal assessment tool that seeks to incorporate temporal trends of the clusters that are “high-high” and “high-low”. Two classifications support the index: severity and temporal duration. We define severity as the number of times a county is statistically significant and temporal duration captures the number of consecutive days a county is a hotspot. Conclusions: The space-time classification index provides a statistically robust measure of the spatial patterns of COVID-19 hotspots. Spatial information is not captured through measures like the positivity rate, which merely divides the number of cases by tests conducted. The index proposed in this paper can guide intervention efforts by classifying counties with six-levels of importance.
All-cause mortality counts allow public health authorities to identify populations experiencing excess deaths from pandemics, natural disasters, and other emergencies. Delays in the completeness of mortality counts may contribute to misinformation because death counts take weeks to become accurate. We estimate the timeliness of all-cause mortality releases during the COVID-19 pandemic for the dates 3 April to 5 September 2020 by estimating the number of weekly data releases of the NCHS Fluview Mortality Surveillance System until mortality comes within 99% of the counts in the 19 March 19 2021 provisional mortality data release. States9 mortality counts take 5 weeks at median (interquartile range 4-7 weeks) to completion. The fastest states were Maine, New Hampshire, Vermont, New York, Utah, Idaho, and Hawaii. States that had not adopted the electronic death registration system (EDRS) were 4.8 weeks slower to achieve complete mortality counts, and each weekly death per 10^8 was associated with a 0.8 week delay. Emergency planning should improve the timeliness of mortality data by improving state vital statistics digital infrastructure.
Introduction Despite an increasing number of studies, there is as yet no efficient antiviral treatment developed for the disease. In this clinical trial, we examined the efficacy of a novel herbal antiviral preparation comprising Zataria multiflora Boiss, Glycyrrhiza glabra, Cinnamomum Vermont, Allium sativuml, and Syzygium aromaticum in critically ill patients with COVID-19 patients. Methods A total number of 120 ICU-admitted patients requiring pulmonary support with a diagnosis of COVID-19 pneumonia were recruited to the trial. Participants were equally randomized to receive either the novel antiviral preparation sublingually, for up to two consecutive weeks or till discharge, or normal saline as the matching placebo. Clinical and laboratory parameters as well as survival rates were compared between the two groups at the study end. Results The cumulative incidence of death throughout the study period was 8.33% in the medication group and 60% in the placebo group (risk ratio: 0.14; 95% confidence interval [CI], 0.05 to 0.32; P<0.001). Survival rates were significantly higher in the treatment group. Additionally, on day 7, several laboratory factors including white blood cells (WBCs) count, C-reactive protein (CRP), and SpO2 were improved in patients treated with the novel antiviral preparation compared with the placebo group. Conclusion The novel antiviral preparation tested in this trial significantly improved the survival rate and reduced mortality in critically ill patients with COVID-19. Thus, this preparation might be suggested as a potentially promising COVID-19 treatment.

ACE2-like carboxypeptidase B38-CAP protects from SARS-CoV-2-induced lung injury - Angiotensin-converting enzyme 2 (ACE2) is a receptor for cell entry of SARS-CoV-2, and recombinant soluble ACE2 protein inhibits SARS-CoV-2 infection as a decoy. ACE2 is a carboxypeptidase that degrades angiotensin II, thereby improving the pathologies of cardiovascular disease or acute lung injury. Here we show that B38-CAP, an ACE2-like enzyme, is protective against SARS-CoV-2-induced lung injury. Endogenous ACE2 expression is downregulated in the lungs of SARS- CoV-2-infected hamsters, leading…
Heparin interacts with the main protease of SARS-CoV-2 and inhibits its activity - The ability of SARS-CoV-2 to replicate in host cells is dependent on its main protease (M^(pro), also called 3CLpro) that cut the viral precursor polyproteins and is a major target for antiviral drug design. Here, we showed that heparin interacts with the M^(pro) of SARS-CoV-2 and inhibits its activity. Protein fluorescence quenching showed that heparin strongly binds to the M^(pro) protein with dissociation constants K(D) of 16.66 and 31.60 μM at 25 and 35 °C, respectively. From thermodynamic…
Resolvin T-series Reduce Neutrophil Extracellular Traps - The newly identified thirteen-series Resolvins (RvTs) regulate phagocyte functions and accelerate resolution of infectious inflammation. Since SARS-CoV-2 elicits uncontrolled inflammation involving neutrophil extracellular traps (NETs), we tested whether stereochemically defined RvTs regulate NET formation. Using microfluidic devices capturing NETs in PMA-stimulated human whole blood, the RvTs, RvT1-RvT4, 2.5 nM each, potently reduced NETs. With IL-1b-stimulated human neutrophils, each RvT dose-…
Host cell-intrinsic innate immune recognition of SARS-CoV-2 - Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) emerged at the end of 2019 and caused the pandemic of coronavirus disease 2019 (COVID-19). Basic and clinical investigations indicate that severe forms of COVID-19 are due in part to dysregulated immune responses to virus infection. The innate immune system is the first line of host defense against most virus infections, with pathogen recognition receptors detecting SARS-CoV-2 RNA and protein components and initiating pro-inflammatory…
Deubiquitinases: From mechanisms to their inhibition by small molecules - Deubiquitinases (DUBs) are specialized proteases that remove ubiquitin from substrates or cleave within ubiquitin chains to regulate ubiquitylation and therefore play important roles in eukaryotic biology. Dysregulation of DUBs is implicated in several human diseases, highlighting the importance of DUB function. In addition, many pathogenic bacteria and viruses encode and deploy DUBs to manipulate host immune responses and establish infectious diseases in humans and animals. Hence, therapeutic…
SARS-CoV-2 N Protein Induces Acute Kidney Injury via Smad3-Dependent G1 Cell Cycle Arrest Mechanism - COVID-19 is infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and can cause severe multiple organ injury and death. Kidney is one of major target organs of COVID-19 and acute kidney injury (AKI) is common in critically ill COVID-19 patients. However, mechanisms through which COVID-19 causes AKI remain largely unknown and treatment remains unspecific and ineffective. Here, the authors report that normal kidney-specifically overexpressing SARS-CoV-2 N develops AKI, which…
Intestinal Collinsella may mitigate infection and exacerbation of COVID-19 by producing ursodeoxycholate - The mortality rates of COVID-19 vary widely across countries, but the underlying mechanisms remain unelucidated.

Raw sequencing data of 16S rRNA V3-V5 regions of gut microbiota in 953 healthy subjects in ten countries were obtained from the public database. We made a generalized linear model (GLM) to predict the COVID-19 mortality rates using gut microbiota. GLM revealed that…
Computational prediction of the potential target of SARS-CoV-2 inhibitor plitidepsin via molecular docking, dynamic simulations and MM-PBSA calculations - Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication depends on the interaction between the viral proteins and the human translation machinery. The cytotoxic peptide plitidepsin was found to inhibit CoV-2 up to 90% at a concentration of 0.88 nM. In vitro studies suggest that this activity may be attributed to the inhibition of the eukaryotic translation elongation factor 1A (eEF1A). However, recent reports raised the potential for other cellular targets which plitidepsin may…
A Genetic Trap in Yeast for Inhibitors of SARS-CoV-2 Main Protease - The ongoing COVID-19 pandemic urges searches for antiviral agents that can block infection or ameliorate its symptoms.

A study of contemporary trends in investing patterns, household savings, and economic investment. - Because household savings and household investments are intertwined and interdependent, they are discussed briefly in this paper. Household savings account for more than half of a country’s capital formation, which fluctuates due to a variety of economic factors such as inflation and interest rates. Households should gradually shift their savings and investments from physical assets to financial assets to avoid a sudden change in wealth. They should also save and invest using a variety of platforms. Trends in investing and saving will be easier to track and measure this way. This year’s domestic saving rate in India is 2.3 percent lower than last year’s and 1.2 percent lower than the year before. Since 2011, general domestic savings have been steadily declining, with the trend continuing into the following year. According to official data, the GDP in 2020 shrank by 23.9%, the least in previous years and the least since the Covid-19 pandemic in previous years. As a result, the information presented in this paper is drawn from and evaluated from other sources - link
