Vaccination and non-pharmaceutical interventions (NPIs) reduce transmission of SARS-CoV-2 infection, but their effectiveness depends on coverage and adherence levels. We used scenario modeling to evaluate their effects on cases and deaths averted and herd immunity. NPIs and vaccines worked synergistically in different parts of the pandemic to reduce disease burden.

The five boroughs of New York City (NYC) were early epicenters of the Covid-19 pandemic in the United States, with over 380,000 cases by May 31. High caseloads were also seen in nearby counties in New Jersey (NJ), Connecticut (CT) and New York (NY). The pandemic started in the area in March with an exponential rise in the number of daily cases, peaked in early April, briefly declined, and then, showed clear signs of a second peak in several counties. We will show that despite control measures such as lockdown and restriction of movement during the exponential rise in daily cases, there was a significant net migration of households from NYC boroughs to the neighboring counties in NJ, CT and NY State. We propose that the second peak in daily cases in these counties around NYC was due, in part, to the movement of people from NYC boroughs to these counties. We estimate the movement of people using “Change of Address” (CoA) data from the US Postal Service, provided under the “Freedom of Information Act” of 1967. To identify the timing of the second peak and the number of cases in it, we use a previously proposed SIR model, which accurately describes the early stages of the coronavirus pandemic in European countries. Subtracting the model fits from the data identified, we establish the timing and the number of cases, NCS, in the second peak. We then related the number of cases in the second peak to the county population density, P, and the excess Change of Address, ECoA, into each county using the simple model N_CS~P^α E_CoA^β which fits the data very well with α = 0.68, β = 0.31 (R^2 = 0.74, p = 1.3e-8). We also find that the time between the first and second peaks was proportional to the distance of the county seat from NY Penn Station, suggesting that this migration of households and disease was a directed flow and not a diffusion process. Our analysis provides a simple method to use change of address data to track the spread of an infectious agent, such as SARS-Cov-2, due to migrations away from epicenters during the initial stages of a pandemic.

<li><strong>The requisite for acid generation to solubilize insoluble salts may account for surge of glucose levels in some diabetes patients</strong> -
|
||||
<div>
|
||||
Diabetes is a comorbidity of COVID-19, and the mortality may be pertinent to the wide distribution of insoluble and stiff salts such as calcium oxalate in diabetic sufferers. As an intrinsic self-protective mechanism, tissues in diabetic individuals may build up hydrogen-bonding-capable molecules such as glucose for the generation of acids which can solubilize insoluble and stiff salts or crystals.

<li><strong>A Guilt-Free Strategy Increase Self-Reported Non-Compliance with COVID-19 Preventive Measures: Experimental Evidence from 12 Countries</strong> -
|
||||
<div>
|
||||
Studies of citizens’ compliance with COVID-19 preventive measures routinely rely on survey data. While essential, public health restrictions provide clear signals of what is socially desirable in this context, creating a potential source of response bias in self-reported measures of compliance. In this research, we examine whether the results of a guilt-free strategy that was used by Daoust et al. (2020) to loosen this constraint are generalizable across twelve countries, and whether the treatment effect varies across subgroups. Our findings show that the guilt-free strategy is a very useful tool in every country included, increasing respondents’ proclivity to report non-compliance by 9 to 16 percentage points. This effect holds for different subgroups based on gender, age and education. We conclude that the inclusion of this strategy should be the new standard for survey research that aims to provide crucial data on the current pandemic.

<li><strong>Pairing Facts with Imagined Consequences Improves Pandemic-Related Risk Perception</strong> -
|
||||
<div>
|
||||
The COVID-19 pandemic reached staggering new peaks during an ongoing global resurgence at the end of 2020. Although public health guidelines initially helped to slow the spread of disease, widespread pandemic fatigue and prolonged harm to financial stability and mental wellbeing have contributed to this resurgence. In this late stage of the pandemic, it is clear that new interventions are needed to support long-term behavior change. Here, we examined subjective perceived risk about COVID-19, and the relationship between perceived risk and engagement in risky behaviors. In Study 1 (N = 303), we found that subjective perceived risk is inaccurate but predicts compliance with public health guidelines. In Study 2 (N = 760), we developed a multi-faceted intervention designed to realign perceived risk with actual risk. Participants completed one of three variants of an episodic simulation task; we expected that imagining a COVID-related scenario would increase the salience of risk information and enhance behavior change. Immediately following the episodic simulation, participants completed a risk estimation task with personalized feedback about local risk levels. We found that information prediction error, a measure of surprise, drove beneficial change in perceived risk and willingness to engage in risky activities. Imagining a COVID-related scenario beforehand enhanced the effect of prediction error on learning. Importantly, our intervention produced lasting effects that persisted after a 1-3 week delay. Overall, we describe a fast and feasible online intervention that effectively changed beliefs and intentions about risky behaviors.

<li><strong>Combinatorial optimization of mRNA structure, stability, and translation for RNA-based therapeutics</strong> -
|
||||
<div>
|
||||
Therapeutic mRNAs and vaccines are being developed for a broad range of human diseases, including COVID-19. However, their optimization is hindered by mRNA instability and inefficient protein expression. Here, we describe design principles that overcome these barriers. We develop a new RNA sequencing-based platform called PERSIST-seq to systematically delineate in-cell mRNA stability, ribosome load, as well as in-solution stability of a library of diverse mRNAs. We find that, surprisingly, in-cell stability is a greater driver of protein output than high ribosome load. We further introduce a method called In-line-seq, applied to thousands of diverse RNAs, that reveals sequence and structure-based rules for mitigating hydrolytic degradation. Our findings show that superfolder mRNAs can be designed to improve both stability and expression that are further enhanced through pseudouridine nucleoside modification. Together, our study demonstrates simultaneous improvement of mRNA stability and protein expression and provides a computational-experimental platform for the enhancement of mRNA medicines.

<li><strong>Severity of SARS-CoV-2 infection as a function of the interferon landscape across the respiratory tract of COVID-19 patients.</strong> -
|
||||
<div>
|
||||
The COVID-19 outbreak driven by SARS-CoV-2 has caused more than 2.5 million deaths globally, with the most severe cases characterized by over-exuberant production of immune-mediators, the nature of which is not fully understood. Interferons of the type I (IFN-I) or type III (IFN-III) families are potent antivirals, but their role in COVID-19 remains debated. Our analysis of gene and protein expression along the respiratory tract shows that IFNs, especially IFN-III, are over-represented in the lower airways of patients with severe COVID-19, while high levels of IFN-III, and to a lesser extent IFN-I, characterize the upper airways of patients with high viral burden but reduced disease risk or severity; also, IFN expression varies with abundance of the cell types that produce them. Our data point to a dynamic process of inter- and intra-family production of IFNs in COVID-19, and suggest that IFNs play opposing roles at distinct anatomical sites.

<li><strong>Rapid characterization of spike variants via mammalian cell surface display</strong> -
|
||||
<div>
|
||||
The SARS-CoV-2 spike (S) protein is a critical component of subunit vaccines and a target for neutralizing antibodies. Spike is also undergoing immunogenic selection with clinical variants that increase infectivity and partially escape convalescent plasma. Here, we describe spike display, a high-throughput platform to rapidly characterize glycosylated spike ectodomains across multiple coronavirus-family proteins. We assayed ~200 variant SARS-CoV-2 spikes for their expression, ACE2 binding, and recognition by thirteen neutralizing antibodies (nAbs). An alanine scan of the N-terminal domain (NTD) highlights a public class of epitopes in the N3 and N5 loops that are recognized by most of the NTD-binding nAbs assayed in this study. Some clinical NTD substitutions abrogate binding to these epitopes but are circulating at low frequencies around the globe. NTD mutations in variants of concern B.1.1.7 (United Kingdom), B.1.351 (South Africa), B.1.1.248 (Brazil), and B.1.427/B.1.429 (California) impact spike expression and escape most NTD-targeting nAbs. However, two classes of NTD nAbs still bind B.1.1.7 spikes and neutralize in pseudoviral assays. B.1.1351 and B.1.1.248 include compensatory mutations that either increase spike expression or increase ACE2 binding affinity. Finally, B.1.351 and B.1.1.248 completely escape a potent ACE2 peptide mimic. We anticipate that spike display will be useful for rapid antigen design, deep scanning mutagenesis, and epitope mapping of antibody interactions for SARS-CoV-2 and other emerging viral threats.

<li><strong>Sequence analysis of SARS-CoV-2 in nasopharyngeal samples from patients with COVID-19 illustrates population variation and diverse phenotypes, placing the in vitro growth properties of B.1.1.7 and B.1.351 lineage viruses in context.</strong> -
|
||||
<div>
|
||||
New variants of SARS-CoV-2 are continuing to emerge and dominate the regional and global sequence landscapes. Several variants have been labelled as Variants of Concern (VOCs) because of perceptions or evidence that these may have a transmission advantage, increased risk of morbidly and/or mortality or immune evasion in the context of prior infection or vaccination. Placing the VOCs in context and also the underlying variability of SARS-CoV-2 is essential in understanding virus evolution and selection pressures. Sequences of SARS-CoV-2 in nasopharyngeal swabs from hospitalised patients in the UK were determined and virus isolated. The data indicated the virus existed as a population with a consensus level and non-synonymous changes at a minor variant. For example, viruses containing the nsp12 P323L variation from the Wuhan reference sequence, contained minor variants at the position including P and F and other amino acids. These populations were generally preserved when isolates were amplified in cell culture. In order to place VOCs B.1.1.7 (the UK Kent variant) and B.1.351 (the South African variant) in context their growth was compared to a spread of other clinical isolates. The data indicated that the growth in cell culture of the B.1.1.7 VOC was no different from other variants, suggesting that its apparent transmission advantage was not down to replicating more quickly. Growth of B.1.351 was towards the higher end of the variants. Overall, the study suggested that studying the biology of SARS-CoV-2 is complicated by population dynamics and that these need to be considered with new variants.

<li><strong>A recombinant receptor-binding domain in trimeric form generates completely protective immunity against SARS-CoV-2 infection in nonhuman primates</strong> -
|
||||
<div>
|
||||
Safe and effective vaccination is critical to combatting the COVID-19 pandemic. Here, we developed a trimeric SARS-CoV-2 receptor-binding domain (RBD) subunit vaccine candidate that simulates the natural structure of the spike (S) trimer glycoprotein. Immunization with RBD-trimer induced robust humoral and cellular immune responses and a high level of neutralizing antibodies that were maintained for at least 4 months. Moreover, the antibodies that were produced in response to the vaccine effectively neutralized the SARS-CoV-2 501Y.V2 variant. Of note, when the titers of the antibodies dropped to a sufficiently low level, only one boost quickly activated the anamnestic immune response, resulting in complete protection against the SARS-CoV-2 challenge in rhesus macaques without typical histopathological changes or viral replication in the lungs and other respiratory tissues. Our results indicated that immunization with SARS-CoV-2 RBD-trimer could raise long-term and broad immunity protection in nonhuman primates, thereby offering an optimal vaccination strategy against COVID-19.

<li><strong>Separable Associations Between Perceived Positive and Negative Online Experiences and Loneliness in Peruvian Adolescents During Physical Isolation in Response to COVID-19</strong> -
|

<div>
|
||||
COVID-19 lockdowns around the world have markedly disrupted adolescents’ in-person social networks, putting them at risk for social isolation, loneliness and their detrimental consequences. During lockdown, social media can help adolescents to maintain and develop relationships across distance, particularly with peers. In this longitudinal, observational study following 735 Peruvian adolescents (11-17 years old) from low-to-middle income urban settings, we investigated whether online experiences relate to loneliness during initial stages of lockdown in Perú. We found that loneliness generally did not change between week six and week eleven of lockdown, was higher for females and similar for all grades. Both positive and negative online experiences were more frequent for older students, and females experienced more negative online experiences than males. Loneliness was negatively associated with positive online experiences, with the reverse pattern for negative online experiences, when controlling for family social support and screen time. Our results highlight the association between online experiences and well-being, suggesting that positive online experiences can be an important vehicle for peer relationships in the face of lockdown.

IMPORTANCE: The emergency of COVID-19 requires the implementation of urgent strategies to prevent the spread of the disease, mainly in health personnel, who are the most exposed and has the highest risk of becoming infected with the SARS-COV-2. Drug repurposing is a pragmatic strategy, a faster and cheaper option, compared to the new drug development that has proven successful for many drugs and can be a key tool in emergency situations such as the current one that requires quick action. In addition, considering the limited access to vaccines for developing countries, preventive use of ivermectin can be a palliative that minimizes the risks of infection. OBJECTIVE: To evaluate the protective effect of the combination Ivermectin / Iota- Carrageenan (IVER/IOTACRC), intensive treatment with repeated administration in oral- and nasal-spray, respectively, as a prophylaxis treatment prior to exposure to SARS-CoV-2, in health personnel at Public Healthcare Centers. PARTICIPANTS, DESIGN AND SETTING: Randomized controlled 1-1 clinical trial in Personal Health, n = 234. The subjects were divided into experimental (EG: n=117; 39.6 ± 9.4 years old, 65F) and control groups (CG: n=117; 38.4 ± 7.4 years old, 61F). The EG received Ivermectin orally 2 tablets of 6 mg = 12 mg every 7 days, and Iota-Carrageenan 6 sprays per day for 4 weeks. All participants were evaluated by physical examination COVID-19 diagnosed with negative RT-PCR at the beginning, final, and follow-up of the protocol. Differences between the variables were determined using the Chi-square test. The proportion test almost contagious subject and the contagion risk (Odds Ratio) were calculated using software STATA. The level of statistical significance was reached when p-Value < 0.05. RESULT: The number of subjects who were diagnosed with COVID-19 in EG was lower, only 4 of 117 (3.4%) than subjects in CG: 25 of 117 (21.4%) (P-Value = 1.10-5). Nineteen patients had mild symptoms, 4 were in EG whereas, 15 were in CG (p-Value = 0.001). Seven subjects were moderate, and 3 with severe diagnostics, all them in CG. The probability (Odds Ratio) of becoming ill with COVID-19 was significantly lower in EG with values of 0.13, 95% 0.03 to 0.40; p-Value = 1.10-4, this value (<1) indicates a protective effect of the IVER/IOTACRC in the EG. Logistic regression test demonstrated that treatment was effective to prevent COVID-19 (Odds Ratio 0.11, 95% 0.03 to 0.33; p-Value = 1.10-4). We also found that when increase the age, decrease contagious risk (Odds Ratio 0, 93, 95% 0.88 to 0.98, p-Value= 0, 02). On the other hand, the probability of contracting COVID-19 was dependent on the patient9s preexisting comorbidity (Odds Ratio 5.58, 95% 2.20 to 14.16, p-Value = 1.10-5). The other variables sex and designation were independent. CONCLUSION: The intensive preventive treatment (short-term) with IVER/IOTACRC was able to reduce the number of health workers infected with COVID-19. This treatment had also effect in preventing the severity of the disease, since all patients treated were mild. We propose a new therapeutic alternative for prevention and short-term intervention scheme (intensive) that is of benefit of the health worker in this pandemic accelerated time. This intervention did not produce lack of adherence to treatment or adverse effects.

Background: The emergence of COVID-19 requires alternative treatments based on the reuse of drugs as a strategy to prevent the progression of the disease in patients infected with SARS-COV-2. The goal was to evaluate the use of ivermectin in mild stage outpatients to heal and / or reverse the progression of COVID-19 disease towards the development of moderate or severe stages. Methods: Cluster Assigned Clinical Trial (2:1) in outpatients, n = 234. The subjects were divided into experimental (EG: n = 110) and control groups (CG: n = 62). The EG received ivermectin orally 4 drops of 6 mg = 24 mg every 7 days for 4 weeks. All participants were diagnosed by positive RT-PCR for COVID-19 and were evaluated by clinical examination, at the beginning and the end of protocol. Data analyzed were applied the proportion, bivariate, and logical regression tests with level significance p < 0.05. This study was registered at ClinicalTrials.gov Identifier NCT04784481. Findings: Both groups were similar in age, sex, and comorbidities (EG: 56F, median age= 40.0, range: 18.0 - 75.0; CG: 34F, median age = 37.5, range: 18.0 - 71.0). A significant reduction in the symptom numbers was observed in the EG when the medical examination was performed from 5th to 9th days, after starting treatment (p = 0.0026). Although, medical examination from 10th to 14th day, showed a progressive reduction of the percentage symptom numbers, these were not significative in both groups. A higher proportion of medical release was observed in EG (98.2%) vs CG (87.1%) (p = 0.003). EG showed 8 times more chance of receiving medical release than CG (OR 7.99, 95% CI: 1.64 -38.97, p = 0.003). The treatment effect with ivermectin to obtain medical release was analyzed by the logistic regression model based in the following control variables: sex, age, and comorbidities. Then, the chance to obtain medical release was maintained in EG (OR 10.37, 95% CI: 2.05 - 52.04, p = 0.005). Interpretation: Treatment with ivermectin in outpatients with mild stage COVID-19 disease managed to slightly reduce the symptom numbers. Also, this treatment improved the clinical state to obtain medical release, even in the presence of comorbidities. The treatment with ivermectin could significantly prevent the evolution to serious stages since the EG did not present any patient with referral to critical hospitalization.

Previous COVID-19 prognostic models have been developed in hospital settings, and are not applicable to COVID-19 cases in the general population. There is an urgent need for prognostic scores aimed to identify patients at high risk of complications at the time of COVID-19 diagnosis. The RDT COVID-19 Observational Study (RCOS) collected clinical data from patients with COVID-19 admitted regardless of the severity of their symptoms in a general hospital in India. We aimed to develop and validate a simple bedside prognostic score to predict the risk of hypoxaemia or death. 4035 patients were included in the development cohort and 2046 in the validation cohort. The primary outcome occurred in 961 (23.8%) and 548 (26.8%) patients in the development and validation cohorts, respectively. The final model included 12 variables: age, systolic blood pressure, heart rate, respiratory rate, aspartate transaminase, lactate dehydrogenase, urea, C-reactive protein, sodium, lymphocyte count, neutrophil count and neutrophil/lymphocyte ratio. In the validation cohort, the area under the receiver operating characteristic curve (AUROCC) was 0.907 (95% CI, 0.892-0.922) and the Brier Score was 0.098. The decision curve analysis showed good clinical utility in hypothetical scenarios where admission of patients was decided according to the prognostic index. When the prognostic index was used to predict mortality in the validation cohort, the AUROCC was 0.947 (95% CI, 0.925-0.97) and the Brier score was 0.0188. If our results are validated in other settings, the RCOS prognostic index could help improve the decision making in the current COVID-19 pandemic, especially in resource limited-settings.

Background and objective. Long-term pulmonary sequelae following SARS-CoV-2 pneumonia are not yet confirmed, however preliminary observations suggests a possible relevant clinical, functional and radiological impairment. The aim of this study was to identify and characterise pulmonary sequelae caused by SARS-CoV-2 pneumonia at 6-month follow-up. Methods. In this multicenter, prospective, observational cohort study, patients hospitalised for SARS-CoV-2 pneumonia and without prior diagnosis of structural lung diseases were stratified by maximum ventilatory support (oxygen only, continuous positive airway pressure (CPAP) and invasive mechanical ventilation (IMV)) and followed up at 6 months from discharge. Pulmonary function tests and diffusion capacity for carbon monoxide (DLCO), 6 minutes walking test, chest X-ray, physical exam and modified Medical Research Council (mMRC) dyspnoea score were collected. Results. Between March and June 2020, 312 patients were enrolled (83, 27% women; median [IQR] age 61.1 [53.4,69.3] years). The parameters that showed the highest rate of impairment were DLCO and chest-X-ray, in 46% and 25% of patients, respectively. However, only a minority of patients reported dyspnoea (31%), defined as mMRC ≥ 1, or showed a restrictive ventilatory defects (9%). In the logistic regression model, having asthma as comorbidity was associated with DLCO impairment at follow-up, while prophylactic heparin administration during hospitalisation appeared as a protective factor. Need for invasive ventilatory support during hospitalisation was associated with chest imaging abnormalities. Conclusion. DLCO and radiological assessment appear to be the most sensitive tools to monitor patients with COVID-19 during follow-up. Future studies with longer follow-up are warranted to better understand pulmonary sequelae.
