This analytical study has some limitations, as only a single isolate (REMRQ0001/Human/2020/Liverpool) was used to assess the LODs but our results are consistent with other recently-published analyses30,31. To the authors knowledge, all 19 tests evaluated here detect the nucleoprotein, presumably chosen for abundance and relative low mutation rate and therefore hypothesized to pick up all currently known variants32,33. Another limitation is that only one lot per kit was evaluated. There is a growing number of studies suggesting that although antigen detection is less analytically sensitive than nucleic acid amplification techniques, it may strongly correlate with culturable virus, which may be a proxy for transmissibility. Hence Ag-RDTs could be informative for test, trace, isolate processes for the most infectious individuals10–15. Viral loads have been estimated to range from 108 to 1011 gcn/ml in the most infectious patients34–36. The majority of Ag-RDTs evaluated here have an LOD predicted to successfully diagnose infected individuals with higher viral loads in this range across all matrices, except Joysbio that had an LOD of 5.4 × 108 gcn/ml in dry swab. Further, Biocredit, iChroma, Standard-F and Genedia tests had LOD greater than 1.0 × 108 gcn/ml when using swabs placed in Amies and In conclusion, the most sensitive tests with an LOD ≤ 5.0 × 102 pfu/ml (≈ 1.2 ×106 gcn/ml) on dry swabs and direct culture supernatant were Espline, Mologic, Sure-Status and Roche and the le...

Our study has several limitations. UKB is not representative of the general UK population; only 6% of those invited to participate did so.22 Risk factor levels and mortality rates are lower than in the general population, although risk factor associations with mortality for a range of diseases are similar.23 Hence, further studies are warranted in other populations. Our one-sample Mendelian randomisation analysis in UKB had limited power to reliably estimate causal effects as fewer than one thousand participants had been hospitalised after a positive SARS-CoV-2 test and our genetic instrument of 131 variants, while using the most up to date information on LTL-associated variants, accounts for only ∼4% of inter-individual variation in LTL.11 While there are data from large genetic studies of COVID-1924, they could not be used in our analysis because the outcome definitions differed substantially from those we used, and because of their inclusion of within hospital testing that is potentially a collider with LTL and COVID-19 outcomes. Larger sample sizes with comparable disease phenotypes should, therefore, enable more precise evaluation of a potential causal association between shorter LTL and adverse COVID-19 outcomes. In conclusion, in the largest study to date, we provide evidence that shorter LTL, reflecting older biological age, is associated with higher risk of adverse COVID-19 outcomes, independent of several major risk factors for COVID-19.

There are several caveats to the approach adopted in this study. Of note, we only tested the compounds at a single 10 μM concentration, and thus an immediate option to see stronger inhibition of virus replication would be to test higher concentrations of the inhibitors. However, this might result in the identification of additional compounds with antiviral potential but only in a non-physiologically achievable range of concentrations. Thus, extensive compound modification and optimization for increased antiviral potential would be required in subsequent studies and would slow immediate roll-out of a repurposed drug. Given that our goal was to rapidly identify approved drugs as treatment options for COVID-19 and circumvent the lengthy process of progressing inhibitors to approval, we set the threshold at 10 μM and did not consider higher drug concentrations. Options to improve the yield of our screening approach could be to use an alternative structure of 3CL Mpro that was subsequently solved by room temperature X-ray crystallography (27). It reveals the ligand-free structure of the active site and the conformation at near-physiological temperature, and was suggested to be a better target for in silico screening for inhibitors of 3CL Mpro (27). Moreover, additional libraries of approved drugs could be included, for example IUPHAR/BPS (https://www.guidetopharmacology.org/) and ChEMBL (https://www.ebi.ac.uk/chembl/), although they overlap substantially with DrugBank.

Limitations: We acknowledge several limitations. First, our human protein-protein interactome was built using high-quality data from multiple sources; yet it is still incomplete. The PPIs in our interactome is undirected. However, it has been shown that incorporating directionality of the human PPI does not change network proximity results [114]. Therefore, the network associations could be either positive or negative, and require further investigation. In addition, as our network proximity analysis relies on disease-associated genes, literature bias could affect the results because more highly-studied genes are more likely to appear in the dataset. Second, we analyzed expression levels of the key SARS-CoV-2 entry factors and found low expression levels for ACE2 and TMPRSS2. However, we cannot rule out the possibility of SARS-CoV-2 directly targeting the brain via as-yet unidentified mechanisms. Third, possible pathways of neuroinflammation and microvascular injury were tested using data of either individuals with AD or COVID-19, but not both. Future studies using genetics and multi-omics data from individuals with both AD and COVID-19 will be needed to confirm and extend these network-based findings. The significance of our findings in the context of the general population of COVID-19 frequently suffering from “brain fog” without a formal diagnosis of AD needs further investigation.

There were limitations to the study. First, as this was not a randomized controlled trial, unmeasured confounders could have distorted the overall findings. To minimize this possibility, we evaluated only counties in the US and adjusted for the most important characteristics of these counties. Second, although we chose the date of lockdown as the day on which the local government issued a “stay-at-home” order, other dates such as the date of a travel ban or school closing could also have been chosen. In a sensitivity analysis, we considered several of these possibilities (e.g. school closing, workplace closing, cancellation of public events, restrictions on gatherings, etc.) and found that the use of these dates produced very similar results to those of our main findings. Third, these data were generated in the US and may not apply to other countries around the world, which may have different characteristics and attitudes and adherence to public health policies such as masking and social distancing. Fourth, we did not consider the adherence of the residents in the counties to the lockdown order and did not evaluate the possible adverse effects of lockdowns including loss of income and productivity, mental health issues and “lockdown fatigue”. Notwithstanding these limitations, our findings have important public health implications. Local state and municipal governments should issue an immediate lockdown order when only a few cases of COVID-19 are ascertained in their communit...

Considering power limitations of our trial, we observed similar trends towards improvement in the primary outcome among patients in the convalescent plasma group transfused within 7 days of symptom onset and those who received convalescent plasma with higher-titers of neutralizing anti-SARS-CoV-2 antibody. In the context of emerging SARS-CoV-2 variants, some of which may be associated with greater transmissibility and more severe illness (20), convalescent plasma may offer distinct therapeutic advantages. Since convalescent plasma, which contains polyclonal antibodies, may be donated and transfused locally, and its use may be more adaptable to rapidly changing local viral ecology than other interventions. In contrast, monoclonal antibody therapies may need to be repeatedly engineered and combined to optimize potency among emergent SARS-CoV-2 variants (21,22). Further, since collection and distribution of convalescent plasma units can be performed using existing blood donation protocols and infrastructure, convalescent plasma may be more scalable for use in low- and middle-income countries. Although clinical status at 28 days was not significantly different between treatment groups, 28-day mortality was significantly lower among patients randomized to receive convalescent plasma. Although this secondary outcome was pre-specified, our study was not powered to detect a difference in mortality and analyses of our secondary outcomes were not adjusted for multiplicity.

Limitations of the study: The in vitro FRNT assays we report here do not measure the effect of complement or antibody dependent cell mediated cytotoxicity which may enhance neutralization in vivo. The role that T cells play in immunity to SARS-CoV-2 and in particular protection from severe disease is unknown and worthy of investigation, but recent findings suggest that CD4 and CD8 T cell responses raised to ancestral strains are minimally impacted by the variants (Alison Tarke et al., 2021;Skelly et al., 2021). It will be interesting to determine the directionality of neutralization between the different variant viruses and naturally acquired antibody responses to them. For instance, there is some suggestion in this report that plasma induced by B.1.1.7 is better able to neutralize B.1.351 and P.1. Measuring neutralization of viral variants by B.1.351 and P.1 serum will give a better idea of cross protection against the other strains.

Within the limitations of high MOIs and incomplete loss of ZDHHC expression following siRNA, the observation suggest that ZDHHC9 influences the first round of infection, while ZDHHC20 might not. Next, we utilized the viral supernatants produced from the 10 h infections in cells silenced for either ZDHHC20 or ZDHHC9, and used them to infect naïve control cells. Supernatants were first adjusted to comparable amounts of E-RNA copies per ml (Figure S7D). Approximately 50 E copies were then added per target cell for infection. The infectivity was monitored 6 h after viral inoculation by measuring the total RNA of E and RdRP, as well as sub-genomic E RNA (E-sub_gen), which is a more accurate proxy for viral replication. The infectivity of virions produced from either ZDHHC20 and ZDHHC9 silenced cells was 25% to 30% lower than that of control virions, based on total and sub-genomic E RNA, respectively (Figure 7H). A similar trend was observed for RdRp RNA. These data indicate that ZDHHC20-mediated S-acylation contributes to SARS-CoV-2 infection by promoting the production of fully infectious virions. Finally, given the here identified importance of cholesterol and sphingolipid-rich domains, we tested whether pharmacological inhibition of sphingolipid biogenesis, could affect SARS-CoV-2 infection. We used the fungal metabolite Myriocin, which targets serine palmitoyltransferase-1 at early steps of sphingosine biosynthesis and fully depletes sphingolipids in cells in 5 days. We also t...

Limitations and further directions: All protein interaction assays have limitations intrinsic to each method. Y2H assays are limited by the fact that proteins are exogenously expressed with functional assay tags and targeted to the nucleus. The heterologous nature of the assays and circumvention of physiological transcriptional regulation are limitations, but also a benefit in that they enable detection of interactions that might otherwise be missed. For example, screens that rely on the expression of one or both partners in a given cell line and growth condition might miss interactions for proteins that are not expressed in that cell line, even where these interactions are important in other tissues (Hikmet et al., 2020). Despite these limitations, it has been demonstrated repeatedly that Y2H systems, when quality controlled by orthogonal validation with empirically benchmarked assays as done here, yield high-quality interactions that enable important and robust biological insights (Altmann et al., 2020; Choi et al., 2019; Luck et al., 2020; Rolland et al., 2014; Yu et al., 2008). A known issue with every carefully conducted interaction assay is that true interactions can be missed, with only 20-40% of reference interactions being detectable by any single assay (Braun et al., 2009; Choi et al., 2019; Luck et al., 2020; Yu et al., 2008). This was a major motivation for applying complementary parallel approaches in this study. Future efforts might expand the barcoded ORFeome a...

One limitation of this study is that the inactivation assays were performed in static liquid media as opposed to aerosolized droplets. While the use of visible light in air disinfection has been briefly studied where it was shown that its effectiveness increased approximately 4-fold43, further studies involving dynamic aerosolization are needed to better understand the true potential of visible light mediated viral inactivation. In any case, our study shows the increased susceptibility of enveloped respiratory viral pathogens to 405 nm mediated inactivation in the absence of photosensitizers. The irradiances used in this study are very low and might be easily applied to safely and continuously disinfect occupied areas within hospitals, schools, restaurants, offices and other locations.

However, one caveat of our study is that other cells such as microglia, oligodendrocytes and vascular cells (pericytes, endothelial cells) are not present. Therefore, we cannot exclude that SARS-CoV-2 can infect and possibly replicate efficiently in other cells of the CNS or neuronal cell types such as cortical PV interneurons, midbrain or hindbrain cell types. Despite the low proportion of SARS-CoV-2 infected cells and the fact that infection seemed to be abortive in the hiPSC derived neural cultures, we found evidence for cellular immune activation. In particular, SARS-CoV-2 infection of the neural cultures resulted in the induction of type-III-IFN and IFNλ2/3, but not type-I-IFN or type-II-IFN. This result is in accordance with earlier reports suggesting that SARS-CoV-2 triggers only very mild type-I and type-II-IFN responses, but does trigger a robust type-III-IFN response in cell culture, human airway epithelial cells, ferrets and SARS-CoV-2 infected individuals41,42. In addition, IL-8—a chemotactic factor that attracts leukocytes—was induced in all hiPSC-derived cultures. In lung tissue and peripheral venous blood serum of SARS-CoV-2 infected patients, elevated levels of IL-8 are associated with severe COVID-1943–45. Furthermore, IL-8 has been detected in the CSF of SARS-CoV-2 patients who developed encephalitis, which might be induced by the SARS-CoV-2 associated brain immune response, since SARS-CoV-2 RNA could not be detected in the CSF46. However, how exactly these ...

Inclusion of more potential epitopes from other proteins in the MEVC may suffer the limitation of complexity of the construct besides the challenges associated with the synthesis. A recent study focused on the single protein (spike protein) to generate multiple epitopes such as 13 for MHC I and 3 for MHC II epitopes (Bhattacharya et al., 2020); but, this study has the limitation of not considering the B cell epitopes. Another recent study reported the design of subunit vaccines against SARS-CoV-2 that used only CTL epitopes without considering the significance of B-cell or HTL epitopes (Seema, 2020). Some studies have used other proteins of the virus and restrict the analyses to one of these three epitopes (Joshi et al., 2020). The present study has an advantage in providing a potential MEVC as it contains all three types of epitopes such as CTL, HTL and B cell epitopes. This in silico study is an attempt to describe the potential immunogenic target over the structural proteins and to propose a novel MVEC, for providing new rays of hope in the initial phase of vaccine development and subsequent experimental validation to confer protection against SARS-CoV-2 infection.

Epidemiological data on COVID-19, due also to limitations in the currently available technology for COVID-19 diagnosis (i.e., high rates of false negatives with nasal or nasopharyngeal swabs [45]) may not reflect the real incidence of the disease in each setting, and should, in general, be interpreted with extreme caution. Further studies should document knowledge, attitudes, and practices of case finding and contact tracing in Italy as well as in other settings. More accurate, acceptable, and sustainable tools are also needed for COVID-19 diagnosis. Limitations of this study include the retrospective nature of data, possible selection bias toward more symptomatic cases due to the nature of the network, and the limitation in the technology currently available for COVID-19 diagnosis. Although the use of swabs is currently recommended as the “gold standard” for COVID-19 diagnosis, it has as major limitation of a high percentage of false negative cases [45]. Future studies, when better diagnostic tools will be available, should aim to confirm the observations of the present study. Strengths of this study include its pragmatic and descriptive nature, and the involvement of many pediatric centers in the national territory. More clinical and epidemiological studies are needed to further document the real incidence, presentation, risk factors and outcomes of children with COVID-19 infection in different pediatric subpopulations, to better characterize children at higher risk of the ...

Limitations of Study: The current study, although extensive in regard to immunological analyses performed, is limited by a relatively small COVID-19 patient cohort size (acute phase n = 26, 5-months n = 17, and 9-months n = 13). Here, we assessed SARS-CoV-2-specific immune responses in moderately and severely sick COVID-19 patients who required hospitalization, however, we were not able to include asymptomatic or mild cases. Therefore, the longitudinal characteristics and magnitude of the immune responses observed in the current COVID-19 patient cohort may only be applicable to hospitalized patients.

Strengths and Limitations: The Zoe platform affords a unique opportunity to prospectively link testing behaviours with incident symptoms in a large user base comprising ∼6% of the UK population. The UMD-Facebook platform, though smaller in size and slightly different in survey design, corroborates temporal trends over in the broader population. To our knowledge, this has enabled the first time-varying estimate of testing rates amongst individuals that qualify for COVID-19 tests over the course of the pandemic. Both platforms could be leveraged to track the testing and knowledge gaps, in real time, allowing the effectiveness of interventions, such as improved messaging on when and where to test, to be assessed. We acknowledge a number of limitations to this study. Digital surveys include selected populations not necessarily representative of the wider population. Such platforms have well-documented biases in demographic age, sex, and socioeconomic factors which we adjusted for in our analyses.18, 32 In addition, digital surveys may not be generalizable, as they may be enriched for health-councious internet-connected participants, and thus underestimate disparities in at-risk demographic groups. We show that symptom-tracking app participants and those with smartphones have higher testing rates than all UMD-Facebook survey respondents. Confounding and measurement bias in this observational study using self-reported covariates and outcomes may also cause us to miss other importan...

Our study has some limitations, principally that the results are based on computational modeling of COVID-19 pathophysiology, rather than data from patients with COVID-19. Investigating the issues raised here in clinical trials is likely to prove challenging both from an ethical and practical point of view, however, and suitable animal models of COVID-19 pathophysiology to study these questions are yet to emerge (52). In these circumstances, we hope that insights from detailed computational models that recapitulate patient breathing patterns and lung mechanics can provide useful evidence with which to inform current debate.

This study has several limitations. The criteria for plasma donation restricted participation to healthy people under 60 years of age. Further, the survey responses showed that most participants had relatively mild COVID-19 disease, although asymptomatic participants were underrepresented and very few were hospitalized. These factors indicate that the results may not be generalizable to populations who are older than 60, have severe disease, have comorbidities, or to asymptomatic patients. Most participants only had one serum sample collected, so there is limited data on the change in antibody titers over time. The variability in the nAb response would require evaluation of larger numbers of convalescent patients in order to yield a better understanding of predictive factors. This study also has several strengths. We present the IgG response in over 200 participants and nAbs in 145 participants. We also collected follow-up data for those participants who had a strong IgG and nAbs response at baseline. The information on illness severity and PCR results from both diagnosis and convalescent time-points provided a fuller clinical picture.

Our study is subject to multiple limitations. The COG-UK dataset has a limited sequencing coverage across England and cluster sizes detected will under-estimate absolute numbers (Supplementary Figure 12). The dates of country-specific travel restriction guidance was aligned with the date of travel-related case sampling, the earliest date reliably available. The effect of this should not however markedly affect results or conclusions; the period of travel restrictions are long and the effect size seen is large and therefore this discrepancy is unlikely to account for the significant difference observed. Further, most countries accounting for the imported SARS-CoV-2 cases went into a period of a travel restriction over the study period; by using a date later than the date of return from travel, we are more likely to over-represent contacts for countries under ‘travel-restriction’ guidance. Our study evaluates a period of time following a national lockdown and the associated reduced travel would likely exaggerate the diversity of genomes when compared with the COG-UK dataset. Outcomes such as travel and the number of contacts are self-reported by cases which will have inherent biases. Finally, there will be an artificial reduction in cases at the end of the study period when accounting for case incubation period, testing and report, with data provided 3 days after study close.

4.2 Caveats and areas for further development: By the very nature of the model being a simple representation of a complex system, there are numerous associated caveats to our approach. We restricted our main analysis to only two types of heterogeneity (vulnerability and mixing). In reality, there are many different risk factors affecting transmission dynamics and vaccine uptake, such as age-dependent susceptibility and infectivity. However, we explored two types of heterogeneity alone in order to assess their effects in as simple a setting as possible, without the effects of additional factors. Furthermore, we considered the population split into equal halves. This is relaxed somewhat in further work in the Supplementary Information, in which we show that our qualitative results are robust to this assumption. But a more realistic structure will involve more than two population groups - we outlined above how the analytical framework may be extended to more general population structures. Even extrapolating from the insight that vaccinating mixers first may be optimal for both reducing disease and vaccine escape risk leaves the question of who those mixers are in practice. The group most central to transmission might not simply be a function of age. For example occupation could be taken into account, e.g. those whose roles necessitate contact with others. Another important dimension could be household structure, e.g. those who live with several other people. The interplay betwee...

Our large-scale COVID-19 longitudinal cohort study of students, faculty, and staff at a university campus allocated testing based on estimated risk of infection, rather than mass surveillance, a strategy that could be utilized in a pandemic setting with resource limitations. Most cases were identified through daily attestation surveys, and participants reporting a recent exposure to a case had the highest positivity rate of 2.4%, followed by 1.4% for participants reporting symptoms. We found that baseline testing had a much lower positivity rate of 0.6%, and identified only 15% of cases. Consistent with our findings, random testing of asymptomatic people at the University of Pittsburgh yielded a positivity rate of only 0.4% [5]. In contrast, at Duke University, surveillance testing of asymptomatic persons identified half of all cases [4]. Several college campus outbreaks have been linked to spread in communities and high-risk groups such as long-term care facility residents, and campus outbreaks are known indicators of broader community transmission [27][28]. In our study, SARS-CoV-2 test positivity rates in the university community were substantially lower than in the surrounding areas. This is likely due in part to increased testing availability, particularly for those without symptoms. However, it is also possible that focused testing of high-risk groups prevented and mitigated campus-wide outbreaks. Outbreak testing was an essential part of our testing strategy. In our st...

However, this study also had several limitations. As noted, we used cross-sectional data, so results may be biased by unobserved confounding. Our measures of compliance also relied upon self-report data. While participants provided anonymous responses, responses may still be subject to social desirability concerns. Further, though the pandemic is a salient event, the opportunities for non-compliance are many. Individuals may not recall compliance accurately. Guidelines also changed over the study period, which may have influenced responses. Last, we used data from a non-representative (albeit heterogeneous and weighted) sample with substantial attrition rates. High compliers with COVID-19 are likely to be overrepresented in the data, though high levels of compliance have been found in other samples (Ipsos MORI, 2021). Overall, our results suggest that while compliance with some behaviours is higher in general, individuals comply consistently across recommended compliance behaviours. In line with previous studies (Miller et al., 2020; Wright & Fancourt, 2020), this suggests that motivation is an particularly important determinant of compliance behaviour. Interventions that increase or maintain motivation to comply may be particularly effective at reducing transmission of COVID-19.

Also, mandatory university guidelines including daily symptoms check through cellphone App, handwashing, use of fascial mask, physical distance and gathering limitations have been implemented. Our data suggests that a very low percentage of the individuals has been infected, despite the fact of the use of public transportation and daily commuting between localities in the city with higher prevalence of infection. Seroprevalence studies could help better understand the dynamics of virus transmission in university population as a subgroup of the broader general community setting.

Each of these algorithms may be advisable depending on the programmatic goals and resource limitations of community-based SARS-CoV-2 testing programs. Our analysis provides a quantitative framework for public health practitioners, policymakers, and stakeholders who are planning, implementing, or evaluating community-based testing programs. A reference guide discussing and applying the results of our analyses to programmatic decisions, along with key priorities, benchmarks, and indicators, is included in Supplementary Table 2. For programs intended to minimize missed cases, algorithms (A) NAAT Only, (C) NAAT Confirmation for Sx/Ag-neg & Asx/Ag-pos, and (D) NAAT Confirmation for Ag-neg are most preferable; selecting between these algorithms depends on tolerance for missed cases and available NAAT capacity. For example, at 10% prevalence, (C) NAAT Confirmation for Sx/Ag-neg & Asx/Ag-pos is estimated to miss 1,409 cases (95% UR: 815-2,100) but save 46 NAATs (95% UR: 29-83) for each case missed. For programs intended to minimize NAAT volume, algorithms (B) Ag Only, (C) NAAT Confirmation for Sx/Ag-neg & Asx/Ag-pos, and (E) Repeat Ag for Ag-neg are most preferable; selecting between these algorithms depends on tolerance for missed cases and available NAAT and antigen test capacity. For example, at 10% prevalence, (E) Repeat Ag for Ag-neg is estimated to result in 550 fewer missed cases (95% UR: 301-854) but require 92,200 more antigen tests (95% UR: 91,200-93,200) than (B) Ag Only. ...

Our study has several limitations characteristic of observational studies. First, our data reflects uncontrolled non-random testing and non-random vaccination, both potentially biased across the population. Second, the vaccinated population may differ from the unvaccinated population in its general health status, in its risk of being infected and in its health-seeking behavior. These differences may be both inherent, pre-existing even prior to vaccination, and time-dependent as a result of vaccination itself. Third, during the study period, several viral variants were circulating in Israel. Although the vaccine is expected to be potent against B.1.1.711, which was the most common one12, it is possible that additional variants introduced biases to our estimations of effectiveness across subpopulations, especially if vaccinated at different phases of the epidemic. We address differences in behavior by using the per-test model, which adjusts for differences in the tendency to get tested9, while also comparing the associations identified for the immunization period (after day 28) with those identified in the pre-immunization period for the same population. Yet, behavioral differences which themselves vary with post-vaccination time are harder to correct for. These potential biases are also somewhat minimized due to the rapid pace of freely offered vaccination, together with laboratory results which are also offered free of charge to all members. The high disease rate during the s...

These benefits of TCZ particularly on mortality were demonstrated by several observational studies as well as reviews including observational studies [7,10], however, such results are questionable in view of the inherent limitations of observational studies in terms of design, in addition to patients’ severity and clinical condition variations [23], furthermore, other reviews failed to demonstrate such benefits, the review by Lan SH et al [25] concluded no additional benefits of TCZ on mortality, mechanical ventilation, and ICU admission, although these results should also be looked at cautiously, in view of the substantial heterogeneity in all three outcomes, and of course the observational nature of the included studies. What was agreed upon by almost all the early studies and reviews was the need for well-designed randomized clinical trials. In our review the outcome of short term (28 – 30 day) mortality showed no statistical significance of TCZ, however, this result should be meticulously examined, as it only reports statistical significance, while overlooking potential clinical benefit, the RR was found to be 0.9, however, the 95% CI was 0.8 – 1.01, with an overall effect p value of 0.09. While statistically insignificant, we should understand that the significance was only missed by 0.01 in the 95% CI, more importantly, the result should not be interpreted as lack of effect, but rather as not enough evidence to reject the null hypothesis, and consequently, a clinically ...

There are a number of limitations associated with this review. As our search strategy focused on follow-up, the number of included articles that reported baseline findings was limited, particularly regarding SARS-CoV infection, whilst contemporary SARS-CoV-2 papers had limited follow-up length. Furthermore, estimates of proportion are based on the number of tests performed, and not patients infected, which could be affected by selection bias. Similarly, estimates represent people hospitalised with infection, which may not reflect prevalence in non-hospitalised cases. Caution is required in interpreting overall and summary estimates as heterogeneity in estimated proportions was frequently considerable, which was not completely attributable to the study-level features evaluated. It is likely that variability in case mix and severity within studies contributes to the heterogeneity between them, which may be addressed by individual patient data approaches. We defined radiological sequelae extracted from studies regarded to be attributable to inflammatory and fibrotic responses, however these were not always reported specifically or exclusively, and there are limitations of our predefined radiological outcomes. Ground-glass opacities do not necessarily reflect inflammation and could also reflect retractile fibrosis during follow up. Unfortunately, it is not possible to discriminate between the two without histopathology. Internationally standardised approaches to reporting of post...

While this study highlights strengths of being able to rapidly and remotely assess the impact of various intervention policies on sleep and resting heart rate, there are a few limitations to consider. (1) Only sleep periods between 4-12 hours were analyzed. Shorter sleep periods could increase in frequency with work from home arrangements, but is challenging to detect and distinguish from other brief periods of sedentary behavior, e.g. sitting in bed reading a book or watching television. (2) Oura users typically come from middle to upper class households who could be more cushioned by the impact of COVID-19 and have flexible work arrangements. (3) Sleep quality measures were not obtained, which could be affected by anxiety from the impending loss of jobs or contracting the disease. However, one study showed unchanged or even improved sleep quality during the lockdown, particularly once shift workers and individuals who showed symptoms of COVID-19 were excluded from the analyses 5. (4) As these data were extracted from a large wearable database, we were not able to obtain information about occupations, shift work status, free vs. work days or caregiving responsibilities of these users. Those with additional childcare responsibilities due to school closures or have had a member of the household fall ill might also have had to work late hours in order to catch up on work. Not-withstanding these limitations, our model based on stringency indices was able to capture >50% of the v...

These results should be interpreted in light of certain limitations. First, the survey was conducted in a sample of early volunteers who signed up with 1Day Sooner in April and May of 2020, the earliest weeks of its creation. Volunteers sampled here may not be representative of all challenge trial volunteers, and those who have subsequently volunteered may be different. We also cannot know what proportion of intended volunteers would pass exclusionary screening and consent to participate in a challenge trial. It is possible that this subset would be small or non-representative of the volunteers characterized in our study, similar to observations that altruistic marrow donors represent only a fraction of those who initially volunteer to donate39. However, we have no basis for assuming what specific changes in the composition of challenge trial volunteers would result in. In addition, our sample of controls, whilst recruited to reflect national United States characteristics established by 2019 census data (including age, gender, education and income), are not truly representative of the United States population as a whole. Nor can we rule out, based on our data, the possibility that challenge trial volunteerism reflects unmeasured biases related to the perception of risks and benefits, such as optimism bias10,40; the so-called preventative or therapeutic fallacy, which reflects a common assumption that any treatment offered by medical professionals must be potentially beneficia...

Limitations of the study This research is not without limitations. First, this is a cross-sectional study so it is difficult to accurately elucidate causal relationships between gender, and interpersonal proximity to COVID-19 patients and fear of COVID-19. Second, our study did not control which participants were in quarantine zones and which were not. Quarantine can amplify negative psychological reactions to COVID-19 (Rossi et al., 2020). On the other hand, although the sample is large, most of the participants (75.1%) correspond to the central area of the country, which implies that the results could probably describe the population of this region of the country in particular. Additionally, in our sample the presence of mental illnesses was not controlled. Subjects with a mental disorder have been reported to be at higher risk of negative outcomes because of COVID-19 pandemic with respect to the general population (Carmassi et al., 2020). Conclusions and future directions In our study, we aimed to explore the relationship between sociodemographic factors and fear of COVID-19 in a Cuban population. We identified that gender and knowing a person positive for COVID-19 significantly increases fear levels in the Cuban population. In future studies, it is important to explore other predictors of the negative impact of COVID-19 on mental health in the Cuban population, such as age, socioeconomic status, exposure to the media (television, digital social networks and print media), ...

Weaknesses of this study include use of temperature from the capital city which may vary widely across regions and the limitations of recorded Sars-CoV-2 data. While the use of deaths as the primary endpoint is likely to be the most accurate measure for a large population, it does increase the time between observed parameters and outcomes. The infection fatality rate is also assumed to be static, but is likely to decrease in response to improved treatment and novel therapies, such as the use of Dexamethasone.[20] Calculations using the viral reproductive rate are compound in nature, and a small variation in the number of infections at one point in time will have a large bearing on the number of infections at a later date. However, we believe any predictive model should centre on prediction of the viral reproductive rate, which though widely variable, is predicted by the variables evaluated here, in particular the degree of lockdown. As the focus of investigation turns more to emergent variants, this model could benefit the understanding of their effects in the context of the pandemic as a whole.

Our sample size for the control group was small, and this limitation could have led to this finding. A major limitation of our study is the lack of documentation of clinical and subclinical pulmonary thromboembolic phenomena in the case and control groups. This was highly probable, given the thrombo-inflammatory milieu, and the concomitantly existing cerebral thrombosis. It is possible that this was more common in the case group and could have contributed to the mortality. We did not take pulmonary thromboembolism into account in our analysis, as complete data on CT pulmonary angiography was not available in many patients. In conclusion, our comparison of a thromboembolic cerebral presentation of COVID-19 with a clinically non-thromboembolic presentation of COVID-19, demonstrated higher D-Dimer levels, and a higher mortality in the absence of prominent respiratory compromise, in the former group. The higher mortality was possibly due to the severity of stroke and presence of proximal LVOs. We could not compare mortality in COVID-19 associated strokes with a cohort of non-COVID associated strokes in the same period, as our regular admissions were severely limited during the pandemic. A meta-analysis of stroke in COVID-19 has highlighted that the mean mortality rate among stroke patients with COVID-19 infection was 46.7% compared to only 8.7% among those without COVID-19 infection.(26)

However, a limitation of this analysis is the use of institutional affiliation as an indicator of author nationality. This means that an African author based in a non-African institution would be classified as non-African and a non-African working in an African institution would be classified as African. This misclassification underestimates the contribution of Africa’s large scientific diaspora. Additionally, there was disparity in the geographical representation of African first and last authors. The top four author affiliations were all South African institutions, with the University of Cape Town as the leading institution with the highest number of first and last authors. This is an indicator of the small number of research institutions on the continent and the uneven distribution of these institutions. Over 13% of articles identified were published in the preprint servers. However, for articles that were peer-reviewed and published in journals, we found that 3 African journals featured in the top 15 journals publishing COVID-19 articles on Africa; Pan African Medical journal, South African Medical Journal and African journal of Primary Health Care & Family medicine. This is promising as availability of local journals where African researchers can publish their work can increase publication output. Most of the research work that is undertaken in Africa is meant for the local audience and addresses local concerns and may not be fairly represented by western publishers. So,...

An important limitation of our study is that the surveillance data paint an incomplete picture of the first wave of the outbreak, as cases were underreported due to selective testing and data collection was limited. We used the hospitalisation rate per 100,000 population as a marker of outbreak progression, but this limits the distinction that can be made between risk of infection and risk of severe disease requiring hospital admission. In addition, hospitalisations and deaths among already notified cases may also have been underreported, and we were unable to match all notifications to the municipal register. Furthermore, absence of key individual socio-demographic, socio-economic, and clinical characteristics limits the inferences that can be made about causal factors on an individual patient level. For example, we used city district as an imperfect proxy for SES, but SES at the community or individual level within each city district may have been different. By further stratifying groups by migration background and complementing this with qualitative research (for example, through community focus groups) more insight can be gained into which community-specific targeted prevention strategies may help minimise the disproportionate distribution of COVID-19 in Amsterdam. Our study is the first in the Netherlands to link surveillance data with registration data on migration background to demonstrate the unequal distribution of the burden of COVID-19 within the city of Amsterdam....

Our study has several limitations. First, despite a target trial emulation design and complementary causal inference analyses, it is impossible to fully mitigate biases inherent to observational data. We recognize that in the post-implementation group, unmeasurable or unmeasured confounding factors may influence the estimates for counterfactual treatment effect. This is addressed by the interrupted time series analysis, and we are reassured that this complementary analysis does corroborate the ATT estimate. However, it is possible that unmeasured factors influenced these estimates. Although such interventions are uncommon for ambulatory patients in our health system, we were unable to measure concomitant prescription of other repurposed therapies such as corticosteroids. In addition, date of symptom onset was not available precluding use as inclusion criterion for control group patients. Although our integrated health system provides care for more than two-thirds of all COVID-19 hospitalizations in our region, it is possible that some patients may have been admitted to an ED or hospital outside of our system after testing, resulting in outcome misclassification. Despite intentional and programmatic efforts at both the state and integrated healthcare network level to address healthcare disparities in MAb delivery, we did observe a significantly lower rate of MAb infusion to patients from communities of color. This can be partially understood by the dramatic intercurrent declin...
