    The world continues to face an ongoing viral pandemic that presents a serious threat to human health. The virus underlying the COVID-19 disease, SARS-CoV-2, has caused over 3.2 million confirmed cases TRANS and 220,000 deaths between January and April 2020. Although the last pandemic of respiratory disease MESHD of viral origin swept the globe only a decade ago, the way science operates and responds to current events has experienced a paradigm shift in the interim. The scientific community has responded rapidly to the COVID-19 pandemic, releasing over 16,000 COVID-19 related scientific articles within 4 months of the first confirmed case TRANS, of which at least 6,000 were hosted by preprint servers. We focused our analysis on bioRxiv and medRxiv, two growing preprint servers for biomedical research, investigating the attributes of COVID-19 preprints, their access and usage rates, characteristics of their sharing on online platforms, and the relationship between preprints and their published articles. Our data provides evidence for increased scientific and public engagement (COVID-19 preprints are accessed and distributed at least 15 times more than non-COVID-19 preprints) and changes in journalistic practice with reference to preprints. We also find evidence for changes in preprinting and publishing behaviour: COVID-19 preprints are shorter, with fewer panels and tables, and reviewed faster. Our results highlight the unprecedented role of preprints and preprint servers in the dissemination of COVID-19 science, and the likely long-term impact of the pandemic on the scientific publishing landscape.Competing Interest StatementJP is the executive director of ASAPbio, a non-profit organization promoting the productive use of preprints in the life sciences.

    The need for antiviral drugs is real and relevant. Broad spectrum antiviral drugs have a particular advantage when dealing with rapid disease outbreaks, such as the current COVID-19 pandemic. Since viruses are completely dependent on internal cell mechanisms, they must cross cell membranes during their lifecycle, creating a dependence on processes involving membrane dynamics. Thus, in this study we examined whether the synthesis of glycosphingolipids, biologically active components of cell membranes, can serve as an antiviral therapeutic target. We examined the antiviral effect of two specific inhibitors of GlucosylCeramide MESHD synthase (GCS); (i) Genz-123346, an analogue of the FDA-approved drug Cerdelga(R), (ii) GENZ-667161, an analogue of venglustat which is currently under phase III clinical trials. We found that both GCS inhibitors inhibit the replication of four different enveloped RNA viruses of different genus, organ-target and transmission TRANS route: (i) Neuroinvasive Sindbis virus (SVNI), (ii) West Nile virus (WNV), (iii) Influenza A virus, and (iv) SARS-CoV-2. Moreover, GCS inhibitors significantly increase the survival rate of SVNI-infected MESHD mice. Our data suggest that GCS inhibitors can potentially serve as a broad-spectrum antiviral therapy and should be further examined in preclinical and clinical trial. Analogues of the specific compounds tested have already been studied clinically, implying they can be fast-tracked for public use. With the current COVID-19 pandemic, this may be particularly relevant to SARS-CoV-2 infection MESHD. One Sentence SummaryAn analogue of Cerdelga(R), an FDA-approved drug, is effective against a broad range of RNA-viruses including the newly emerging SARS-CoV-2.

    Background: As the outbreak of COVID-19 has accelerated, an urgent need for finding strategies to combat the virus is growing. Results from in vitro studies suggest that a combination of IFN type I and Type II MESHD may be effective against SARS-CoV MESHD. The aim of this study is to investigate the efficacy of treatment with a recombinant IFN alpha 2b and gamma, provided with standard protocol (Kaletra (lopinavir-ritonavir 200/50 mg; 200/100 mg every 12 hour for 30 days; Chloroquine (250 mg) every 12 hours for 10 days) for COVID-19 patients, compared to standard protocol (IFN alpha 2b/Kaletra/Chloroquine) for COVID-19 hospitalized patients, positive diagnosed for SARS-Cov-2. Methods: Hospitalized adult TRANS patients with qPCR confirmed SARS-Cov-2 will be enrolled in this open-labeled, single center, prospective, randomized and controlled clinical trial. One hundred and twenty eligible patients with confirmed SARS-CoV-2 positivity by qPCR amplification in oropharyngeal/nasopharyngeal swab samples will be enrolled at “Luis Diaz Soto” Hospital, Havana, Cuba. The primary outcomes are the time to 2019-nCoV RNA negativity in patients and the time until progression to severe COVID-19. Discussion: This will be the first randomized controlled trial of a potential treatment for SARC-Cov-2 using the combinations of IFNs. Trial registration: The study is sponsored by Center for Genetic and Biotechnology and Ministry of Health of Cuba and was duly registered April 2020 at http://registroclinico.sld.cu/en/trials/RPCEC00000307-En. Enrolment for this study began in April 11, 2020, and has enrolled one hundred patients as of May-26-2020

    The SARS-CoV-2-like virus found in captive pangolins from Guangdong should be better sequenced.

    Viruses closely related to SARS-CoV-2, which is the virus responsible of the Covid-19 pandemic, were sequenced in several Sunda pangolins (Manis javanica) seized in the Guangdong and Guangxi provinces of China between 2017 and 20191-3. These viruses belong to two lineages: one from Guangdong ( GD MESHD/P) and the other from Guangxi (GX/P). The GD/P viruses are particularly intriguing as the amino-acid sequence of the receptor binding domain of the spike protein is very similar to that of the human SARS-CoV-2 virus (97.4%)2. This characteristic suggests that GD/P viruses are capable of binding human ACE2 receptor and may therefore be able to mediate infection of human cells. Whereas all six GX/P genomes were deposited as annotated sequences in GenBank, none of the two GD/P genomes assembled in previous studies2,3 are currently available. To overcome this absence, I assembled these genomes from the Sequence Read Archive (SRA) data available for SARS-CoV-2-like viruses detected in five captive pangolins from Guangdong. I found the genome assemblies of GD MESHD/P virus of poor quality, having high levels of missing data. Additionally, unexpected reads in the Illumina sequencing data were identified. The GD/P2S dataset2 contains reads that are identical to SARS-CoV-2, suggesting either the coexistence of two SARS-CoV-2-like viruses in the same pangolin or contamination by the human virus. In the four other GD/P datasets1 many mitochondrial reads from pangolin were identified, as well as from three other species, namely, human, mouse and tiger. Importantly, I only identified three polymorphic nucleotide sites between the five GD/P sequences. Such low levels of polymorphism may reasonably be accounted for by sequencing errors alone, thus raising the possibility that the five pangolins seized in Guangdong in March 2019 were infected by the same virus strain, most probably during their captivity.
