Autocratic and democratic leaders have an incentive to misreport data that may reveal policy failure. However, it is easier for autocratic leaders to fabricate data because they are not subject to scrutiny from media, opposition parties, and civil society. This suggests that autocratic governments are more likely to manipulate policy-relevant statistics than democratic governments. It is inherently difficult to test that claim because researchers typically do not have access to data from sources other than the government. The COVID-19 pandemic represents a unique opportunity to examine the relationship between regime type and data manipulation because of its widespread impact, as well as the ability to compare reported with excess deaths and test for statistical anomalies in reported data. Based on regressions for undercounting and statistical irregularities that take into account unintentional mismeasurement, I find that autocratic governments are more likely to deliberately under-report the impact of COVID-19 than their democratic counterparts.

Objectives Post-acute sequalae of SARS-CoV-2 infection (PASC) is not well defined in pediatrics given its heterogeneity of presentation and severity in this population. The aim of this study is to use novel methods that rely on data mining approaches rather than clinical experience to detect signals associated with PASC. Materials and Methods We used a propensity-matched cohort design comparing children identified using the new PASC ICD10CM diagnosis code (U09.9) (N=1250) to children with (N=6250) and without (N=6250) SARS-CoV-2 infection. We used a tree-based scan statistic to identify potential condition clusters co-occurring more frequently in cases than controls. Results We found significant enrichment among children with PASC in cardiac, respiratory, neurologic, psychological, endocrine, gastrointestinal, and musculoskeletal systems, the most significant related to circulatory and respiratory such as dyspnea, difficulty breathing, and fatigue and malaise. Discussion Our study addresses methodological limitations of prior studies that rely on pre-specified clusters of potential PASC-associated diagnoses driven by clinician experience. Future studies are needed to identify patterns of diagnoses and their associations to derive clinical phenotypes. Conclusion We identified multiple conditions and body systems associated with pediatric PASC. Because we rely on a data-driven approach, several new or under-reported conditions and symptoms were detected that warrant further investigation.

<li><strong>High-resolution app data reveal sustained increases in recreational fishing effort in Europe during and after COVID-19 lockdowns</strong> -
|
||
<div>
|
||
It is manifest that COVID-19 lockdowns extensively impacted human interactions with natural ecosystems. One example is recreational fishing, an activity which involves nearly 1 in 10 people in developed countries. Fishing licence sales and direct observations at popular angling locations suggest that recreational fishing effort increased substantially during lockdowns. However, the extent and duration of this increase remain largely unknown due to a lack of objective data. We used four years (2018 to 2021) of anonymous, high-resolution data from a personal fish-finder device to explore the impact of COVID-19 lockdowns on recreational fishing effort in four European countries (Lithuania, the Czech Republic, Denmark, and Germany). We show that device use and, by extension, angling effort increased 1.2-3.8 fold during March-May 2020 and remained elevated even at the end of 2021 in all countries except Denmark. Fishing during the first lockdown also became more frequent during weekdays. Statistical models with the full set of fixed (weekdays, lockdown, population) and random (season, year, administrative unit) factors typically explained 50-70% of the variation, suggesting that device use and angling effort were relatively consistent and predictable through space and time. Our study demonstrates that recreational fishing behaviour can change substantially and rapidly in response to societal shifts, with profound ecological, human well-being and economic implications. We also show the potential of angler devices and smartphone applications to supply data for high-resolution fishing effort analysis and encourage more extensive science and industry collaborations to take advantage of this information.

<li><strong>Alone and in the dark: Sensemaking through online platforms during the COVID-19 pandemic</strong> -

During the lockdowns and social distancing mandates of the coronavirus pandemic, many turned to digital media to obtain information on COVID-19 and to make sense of the pandemic. At the same time, there has been ongoing scrutiny over the trustworthiness and authenticity of online spaces, such as the risk of fake news and algorithms promoting misinformation and echo chambers. In this chapter, I explore a tangential question: How does being aware of the dangers of our digital environment affect our experience of sensemaking? I present my own journey of reflexivity in making sense of the pandemic, and invite the reader to analyze how their awareness of filter bubbles, disinformation, platform governance decisions, and other influences over online spaces affects their experience of sensemaking and sheds light on relationship between the self, the other, and the machine.

<li><strong>UPHOLDING MULTILATERALISM: INDONESIA’S FOREIGN POLICY IN RESPONDING TO COVID-19 PANDEMIC</strong> -
|
||
<div>
|
||
The 2019 Coronavirus disease or COVID-19 has apparently become a new global challenge. Not only did the pandemic drive all actors to make response, but it also affected the relations among them. That Indonesia raised multilateralism in the unprecedented situation while more unilateral or populist actions taken by a number of states encouraged this research. This paper attempts to explain Indonesia’s foreign policy in upholding multilateralism to respond to the COVID-19 during the first year of the pandemic. Such response was intended to mitigate the impacts caused by the pandemic. This research applied holistic constructivism in understanding the determinants of Indonesia’s foreign policy by investigating both domestic and international cause. This research utilized the qualitative method with an explanatory analysis. The findings show that such Indonesia’s foreign policy was driven by its identity constructed by both indigenous norm of gotong royong and global norm of International Health Regulation. The norm-laden or identity-based foreign policy was leading it to uphold multilateralism which was considered appropriate in order to coordinate, collaborate and cooperate with international communities. In addition, Indonesia maintained its trust on and support to the the World Health Organization as the most leading actor in health governance championing fight against the pandemic. This paper argues that the norm factors do matter in Indonesia’s foreign policy in facing uncertainties in the vulnerable and interconnected world. Through the case studied, this paper suggests that looking at the domestic actor as well as the state in international system help provide a better understanding on the state behavior in international relations.

<li><strong>wastewaterSPAdes: SARS-CoV-2 strain deconvolution using SPAdes toolkit</strong> -
|
||
<div>
|
||
Motivation: SARS-CoV-2 wastewater samples are extensively collected and studied because it allows quantitatively assess a viral load in surrounding populations. Additionally, SARS-CoV-2 strain deconvolution gives more insights into pandemic dynamics, and the uprising of new strains. Usually, the solution to the strain deconvolution problem starts with read alignment of wastewater short read sequencing data to the SARS-CoV-2 reference genome. After variants are called and their abundances are estimated, a reference database is used to assign variants to strains, select a subset of strains, and infer relative abundance of these strains based on some mathematical model. Assembly-based methods have its own strengths, but currently reside in the shadow of alignment-based methods. Results: In this paper we propose a new assembly-based approach based on SPAdes toolkit codebase - wastewaterSPAdes, that is able to deconvolve wastewater without a need of read alignment. Our results show that watewaterSPAdes is able to accurately identify strains presented in a sample, and correctly estimate abundances for most of the samples.

<li><strong>Global loss of cellular m6A RNA methylation following infection with different SARS-CoV-2 variants</strong> -
|
||
<div>
|
||
Host-viral interactions during SARS-CoV-2 infection are needed to understand COVID-19 pathogenesis and may help to guide the design of novel antiviral therapeutics. N6-methyladenosine modification (m6A), one of the most abundant cellular RNA modifications, regulates key processes in RNA metabolism during a stress response. Gene expression profiles observed post-infection with different SARS-CoV-2 variants show changes in the expression of genes related to RNA catabolism, including m6A readers and erasers. We found that infection with SARS-CoV-2 variants caused a loss of m6A in cellular RNAs, whereas m6A was detected abundantly in viral RNA. METTL3, the m6A methyltransferase, showed an unusual cytoplasmic localization post-infection. The B.1.351 variant had a less pronounced effect on METTL3 localization and loss of m6A than the B.1 and B.1.1.7 variants. We also observed a loss of m6A upon SARS-CoV-2 infection in air/liquid interface cultures of human airway epithelia, confirming that m6A loss is characteristic of SARS-CoV-2 infected cells. Further, transcripts with m6A modification were preferentially down-regulated post-infection. Inhibition of the export protein XPO1 resulted in the restoration of METTL3 localization, recovery of m6A on cellular RNA, and increased mRNA expression. Stress granule formation, which was compromised by SARS-CoV-2 infection, was restored by XPO1 inhibition and accompanied by a reduced viral infection in vitro. Together, our study elucidates how SARS-CoV-2 inhibits the stress response and perturbs cellular gene expression in an m6A-dependent manner.

<li><strong>Biochemistry-informed design selects potent siRNAs against SARS-CoV-2</strong> -
|
||
<div>
|
||
RNA interference (RNAi) offers an efficient way to repress genes of interest, and it is widely used in research settings. Clinical applications emerged more recently, with 5 approved siRNAs (the RNA guides of the RNAi effector complex) against human diseases. The development of siRNAs against the SARS-CoV-2 virus could therefore provide the basis of novel Covid-19 treatments, while being easily adaptable to future variants or to other, unrelated viruses. Because the biochemistry of RNAi is very precisely described, it is now possible to design siRNAs with high predicted activity and specificity using only computational tools. While previous siRNA design algorithms tended to rely on simplistic strategies (raising fully complementary siRNAs against targets of interest), our approach uses the most up-to-date mechanistic description of RNAi to allow mismatches at tolerable positions and to force them at beneficial positions, while optimizing siRNA duplex asymmetry. Our pipeline proposes 8 siRNAs against SARS-CoV-2, and ex vivo assessment confirms the high antiviral activity of 6 out of 8 siRNAs, also achieving excellent variant coverage (with several 3-siRNA combinations recognizing each correctly-sequenced variant as of September 2022). Our approach is easily generalizable to other viruses as long as a variant genome database is available. With siRNA delivery procedures being currently improved, RNAi could therefore become an efficient and versatile antiviral therapeutic strategy.

<li><strong>TMPRSS2 is essential for SARS-CoV-2 Beta and Omicron infection</strong> -
|
||
<div>
|
||
The COVID-19 pandemic remains a global health threat and novel antiviral strategies are urgently needed. SARS-CoV-2 employs the cellular serine protease TMPRSS2 for entry into lung cells and TMPRSS2 inhibitors are being developed for COVID-19 therapy. However, the SARS-CoV-2 Omicron variant, which currently dominates the pandemic, prefers the endo/lysosomal cysteine protease cathepsin L over TMPRSS2 for cell entry, raising doubts whether TMPRSS2 inhibitors would be suitable for treatment of patients infected with the Omicron variant. Nevertheless, the contribution of TMPRSS2 to spread of SARS-CoV-2 in the infected host is largely unclear. Here, we show that loss of TMPRSS2 strongly reduced the replication of the Beta variant in nose, trachea and lung of C57BL mice and protected the animals from weight loss and disease. Infection of mice with the Omicron variant did not cause disease, as expected, but again TMPRSS2 was essential for ef-ficient viral spread in the upper and lower respiratory tract. These results identify a key role of TMPRSS2 in SARS-CoV-2 Beta and Omicron infection and highlight TMPRSS2 as an attractive target for antiviral intervention.

Background. The annual reappearance of respiratory viruses has been recognized for decades. The onset of the COVID-19 pandemic altered typical respiratory virus transmission patterns. COVID-19 mitigation measures taken during the pandemic were targeted at SARS-CoV-2 respiratory transmission and thus broadly impacted the burden of acute respiratory illnesses (ARIs), in general. Methods. We used the longitudinal Household Influenza Vaccine Evaluation (HIVE) cohort of households in southeast Michigan to characterize mitigation strategy adherence, respiratory illness burden, and the circulation of 15 respiratory viruses during the COVID-19 pandemic determined by RT-PCR of respiratory specimens collected at illness onset. Study participants were surveyed twice during the study period (March 1, 2020, to June 30, 2021), and serologic specimens were collected for antibody measurement by electrochemiluminescence immunoassay. Incidence rates of ARI reports and virus detections were calculated and compared using incidence rate ratios for the study period and a pre-pandemic period of similar length. Results. Overall, 437 participants reported a total of 772 ARIs and 329 specimens (42.6%) had respiratory viruses detected. Rhinoviruses were the most frequently detected organism, but seasonal coronaviruses, excluding SARS-CoV-2, were also common. Illness reports and percent positivity were lowest from May to August 2020, when mitigation measures were most stringent. Study participants were more adherent to mitigation measures in the first survey compared with the second survey. Supplemental serology surveillance identified 5.3% seropositivity for SARS-CoV-2 in summer 2020; 3.0% between fall 2020 and winter 2021; and 11.3% in spring 2021. Compared to a pre-pandemic period of similar length, the incidence rate of total reported ARIs for the study period was 50% lower (95% CI: 0.5, 0.6; p<0.001) than the incidence rate from March 1, 2016, to June 30, 2017. Conclusions. The burden of ARI in the HIVE cohort during the COVID-19 pandemic fluctuated, with declines occurring concurrently with the widespread use of public health measures. It is notable, however, that rhinovirus and seasonal coronaviruses continued to circulate even as influenza and SARS-CoV-2 circulation was low.

Background: The Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), designated as a variant of concern by the World Health Organization, spreads globally and was confirmed as the cause of the Omicron wave of the coronavirus disease 2019 (COVID-19) pandemic in Shanghai, China. The viral shedding duration of Omicron variants needs to be determined. Methods: We retrospectively analyzed 382 patients admitted to a shelter hospital for COVID-19. Of the patients, 8 patients were referred to a designated hospital, 100 were infected asymptomatic patients, and 274 patients had mild COVID-19. Results: The vaccination rates (including fully and boosted) in the asymptomatic and mild COVID-19 patients were 92.00% and 94.16%, respectively. Majority of the studied population showed a first reverse transcription-polymerase chain reaction cycle threshold (Ct) value of 20. For 2565 nasopharyngeal swabs from close or sub-close contacts, the Ct value gradually increased to 35 for 8 days, and the median duration of viral shedding time was 10 days after the first positive detection of the SARS-CoV-2 nuclei acid. Conclusions: Quantitative viral RNA load assays in COVID-19 (BA.2.2.1) close or sub-closed contacts could be used to prevent transmissions and control precautions.

IMPORTANCE The rapid genetic evolution of SARS-CoV-2 and in particular the highly contagious Omicron variant of concern (VoC) may pose problems for rapid and accurate diagnosis of infection especially in health care workers. OBJECTIVE Determine the diagnostic accuracy and robustness of two rapid antigen tests compared to the golden standard, PCR-based diagnostics, for detection of infection with different SARS-CoV-2 Omicron VoC sub lineages in health care workers. DESIGN, SETTING, AND PARTICIPANTS The study included 428 health care workers from the University Hospital Munich Rechts der Isar who reported recent onset of COVID-19 associated symptoms or completed routine diagnostic testing from 24th of May to 22nd of September 2022. All participants gave written informed consent to participate in this study and completed a questionnaire on infection-associated symptoms, prior SARS-CoV-2 infections and vaccination status. INTERVENTIONS During the first visit, two nasal swabs were taken to perform two rapid antigen tests and one oropharyngeal swab for PCR-based diagnosis of SARS-CoV-2 infection. A second set of nasal swabs was taken by participants two days later for repeated performance of the two rapid antigen tests. MAIN OUTCOMES AND MEASURES The accuracy for detection of infection with different SARS-CoV-2 Omicron VoCs with two rapid antigen tests (Test I and Test II) was determined and compared to quantitative SARS CoV-2 RNA levels detected by PCR. RESULTS In a side-by-side comparison, we found that Test I detected viral nucleocapsids from Omicron VoC (BA.5.2.3) at higher dilutions compared to Test II. In the study, that included a total of 428 health care workers, Test I and Test II detected PCR-confirmed SARS-CoV-2 infection with different Omicron VoCs (BA.2, BA.4, BA.5) with a sensitivity of 89.4% (95% CI 81.9% - 94.6%) and of 83.7% (95% CI 75.12% - 90.18%), respectively. Increased sensitivity by Test I was also reflected by earlier detection of SARS-CoV-2 infection, and lesser test sensitivity by Test II was compensated for by a repeated test performed two days later. CONCLUSIONS AND RELEVANCE The results from the study demonstrate the usefulness of rapid antigen tests for detection of infection with the SARS-CoV-2 Omicron VoC and reveal an advantage of a lower detection limit for earlier detection of infection in health care workers.

<li><strong>The impact of the pandemic on student Spanish language proficiency</strong> -

In the aftermath of the COVID-19 pandemic, we continue to take stock of student learning. Although the “crisis-context” (Gacs, et al., 2020) move to fully online instruction may be over, a complete understanding of how student outcomes have been impacted remains. The present study focuses on how student Spanish language proficiency, as measured by the STAMP test, was affected by moving all on-ground language courses online in March 2020 at a small public university in the northeastern US. Comparing median student Spanish language proficiency as well as sub-level proficiencies in reading, writing, speaking, and listening skills across a total of 30 sections of a third-semester Spanish course (n=568) pre- and post-2020, we examined student learning outcomes based upon the modality of instruction. Results revealed a significant increase in students’ overall Spanish language proficiency and significant increases in sub-level proficiencies in three out of the four skills in the online modality. Thus, in spite of the many changes that took place as a result of the COVID-19 pandemic, students’ Spanish language proficiencies were either positively impacted or unimpacted. We discuss the implications of these results and pose questions for on- ground and online language courses moving forward.

Purpose: In March 2020, the UK government announced that people should isolate to reduce the spread of the virus that causes COVID-19. Outside a pandemic, psychosocial factors, such as socialisation and mental health, may impact the relationship between hearing loss and increased dementia risk. We aim to report the impact of psychosocial factors, including social isolation, depression, and engagement in activities, on hearing and cognitive function in younger and older adults during the COVID-19 pandemic. Method: A online survey and behavioural experiment assessed psychosocial factors, hearing, and cognition. Data presented were collected between June 2020 and February 2021. Participants included older (N = 112, MAGE = 70.08) and younger (N = 121, MAGE = 20.52) monolingual speakers of English, without any language or neurological disorders. Results: Multiple regression analyses indicated that older adults displayed poorer hearing and cognitive performance compared to younger adults, and that increased depression was associated with poorer subjective hearing. Other psychosocial factors did not significantly predict hearing or cognitive function. Conclusions: Our findings shed light on whether the relationship between hearing loss and cognitive decline is impacted by psychosocial factors.
