358 | What role does T-cell count play in severe human adenovirus type 55 (HAdV-55) infection? | [
"Title: Emergent severe acute respiratory distress syndrome caused by adenovirus type 55 in immunocompetent adults in 2013: a prospective observational study\nPassage: Recent studies have shown that the immune system plays a crucial role in the clearance of HAdV viremia and survival of the host . Chen et al. reported that, in the acute phase of HAdV-55 infection, patients with severe disease may have high levels of dendritic cells and Th17 cells . In our study, the only patient who recovered from severe infection had higher T-cell counts. Three of the five patients had relatively low T-cell counts when admitted. Our results suggest that these three patients may have been relatively immunocompromised and that a lower T-cell count may be a risk",

"Title: Asymmetry in the Presence of Migration Stabilizes Multistrain Disease Outbreaks\nPassage: Finally, the work discussed here shows a potential effect of human movement between heterogeneous regions. As spatial effects are further studied in epidemic models, it remains to be seen how this phenomenon will extend to more complicated spatial geometries, including more patches and perhaps non-symmetric coupling terms. This work represents a first step towards understanding the role of migration and spatial heterogeneity in dynamical properties of dengue observed in epidemiological data, such as traveling waves of infection in Thailand . Furthermore, because the migration-induced stabilization depends only on the existence of a Hopf bifurcation in the model, it is expected",
"Title: Asymmetry in the Presence of Migration Stabilizes Multistrain Disease Outbreaks\nPassage: Bifurcations from steady state to oscillatory behavior can be associated with an increased number of infection cases, particularly if chaotic oscillations occur, as in previous dengue models . Our results suggest that if control strategies in one region are able to generate enough asymmetry, this could lead to a stabilization of the outbreaks, which would have a positive effect on adjacent regions. Asymmetry could be generated in the effective contact rate by mosquito control, which could include reducing mosquito breeding sites , or through new genetic controls which are under development . Asymmetry in the birth rate could be generated",
"Title: Asymmetry in the Presence of Migration Stabilizes Multistrain Disease Outbreaks\nPassage: To motivate this result, we diffusively coupled two low dimensional Hopf bifurcations with different characteristic frequencies and analyzed the stability of the steady state. We again saw that coupling between asymmetric systems led to stabilization. This indicates that the stabilization in the epidemic model is a result of the underlying dynamics, rather than the details of the model. We suggest that the stabilization may occur as a result of the two different coupled frequencies generating oscillations that tend to cancel each other because of phase differences. This topic will be studied in more detail in a future work.",

Although the S protein of SARS-CoV shares little aminoacid identity , it shares common structural features with S proteins of the other members of the Coronaviridae family.

In addition, the SARS-CoV 3a protein contains a cysteine-rich domain that is involved in the formation of a homodimer to generate the ion channel . Thus, mutation of the cysteine-rich domain blocks the ion conductivity by the 3a protein .

In our view, there is currently no credible evidence to support the claim that SARS-CoV-2 originated from a laboratory-engineered CoV.

"Title: No credible evidence supporting claims of the laboratory engineering of SARS-CoV-2\nPassage: Evolution is stepwise and accrues mutations gradually over time, whereas synthetic constructs would typically use a known backbone and introduce logical or targeted changes instead of the randomly occurring mutations that are present in naturally isolated viruses such as bat CoV RaTG13. In our view, there is currently no credible evidence to support the claim that SARS-CoV-2 originated from a laboratory-engineered CoV. It is more likely that SARS-CoV-2 is a recombinant CoV generated in nature between a bat CoV and another coronavirus in an intermediate animal host. More studies are needed to explore this possibility and resolve the natural origin",
"Title: No credible evidence supporting claims of the laboratory engineering of SARS-CoV-2\nPassage: According to what has been reported , COVID-2019 seems to have similar clinical manifestations to that of the severe acute respiratory syndrome caused by SARS-CoV. The SARS-CoV-2 genome sequence also has ∼80% identity with SARS-CoV, but it is most similar to some bat beta-coronaviruses, with the highest being >96% identity .",
"Title: No credible evidence supporting claims of the laboratory engineering of SARS-CoV-2\nPassage: Currently, there are speculations, rumours and conspiracy theories that SARS-CoV-2 is of laboratory origin. Some people have alleged that the human SARS-CoV-2 was leaked directly from a laboratory in Wuhan where a bat CoV was recently reported, which shared ∼96% homology with the SARS-CoV-2 . However, as we know, the human SARS-CoV and intermediate host palm civet SARSlike CoV shared 99.8% homology, with a total of 202 single-nucleotide variations identified across the genome . Given that there are greater than 1,100 nt differences between the human SARS-CoV-2 and the bat RaTG13-CoV , which are distributed throughout the genome in a"

In November 2002, a cook in Guangdong Province, China, died from an unidentified illness. He had worked at a restaurant in which meat from wild animals was served. On 27 November 2002 Chinese-language media and internet reports were picked up by Canada's Global Public Health Intelligence Network that indicated a flu-like illness was occurring in China .

Most recently, an SARS-related CoV was implicated as the etiological agent responsible for the outbreak in Wuhan, central China. This outbreak is estimated to have started on 12th December 2019 and 17,332 laboratory confirmed cases with 361 deaths as of 3rd February 2020 in China .

"Title: Potential Rapid Diagnostics, Vaccine and Therapeutics for 2019 Novel Coronavirus (2019-nCoV): A Systematic Review\nPassage: The 2019 novel coronavirus , a betacoronavirus, forms a clade within the subgenus sarbecovirus of the Orthocoronavirinae subfamily . The severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus are also betacoronaviruses that are zoonotic in origin and have been linked to potential fatal illness during the outbreaks in 2003 and 2012, respectively . Based on current evidence, pathogenicity for 2019-nCoV is about 3%, which is significantly lower than SARS-CoV and MERS-CoV . However, 2019-nCoV has potentially higher transmissibility than both SARS-CoV and MERS-CoV .",
"Title: Preparation for Possible Sustained Transmission of 2019 Novel Coronavirus\nPassage: Is 2019-nCoV infection severe? To date approximately 14% of cases of 2019-nCoV have been described as severe by WHO, with a case-fatality rate of 2.1%.10 Estimates of severity are usually higher in the beginning of an epidemic due to the identification of the most severely affected cases and decline as the epidemic progresses. However, because many infected persons have not yet recovered and may still die, the case-fatality rate and severity could be underestimated. On January 30, 2020, WHO officially declared the 2019-nCoV epidemic as a Public Health Emergency of International Concern, indicating its concern that countries aside from China",

Among the IFITM family proteins, IFITM5 is unique. Expression of IFITM5: Unlike the other IFITM family proteins, the expression of IFITM5 is not induced by interferons because the region upstream of the ifitm5 gene lacks the interferon regulatory elements . Furthermore, the expression of IFITM5 is mostly restricted to osteoblast cells , while the other IFITM proteins are expressed ubiquitously .

1419 | What effect the use of steroids to suppress inflammation can have? | [
"Title: New aspects in the management of pneumonia\nPassage: The main side effects associated with corticosteroids, especially with prolonged use, are hyperglycemia, myopathy, weight gain, brushing, and osteopenia . As well as these side effects, corticosteroids have strong immunosuppressive effects, raising concerns regarding their use in acute infections, despite their potential effect in controlling excessive inflammatory response. The immunosuppressant effect of corticosteroids is related to dose and treatment duration. For example, the use of 40 mg of prednisolone per day for more than 1 week or 20 mg prednisolone or equivalent per day for a month can produce immunosuppression. In acute infection, a low dose for a short period",
"Title: New aspects in the management of pneumonia\nPassage: Glucocorticosteroid drugs reproduce effects similar to endogenous cortisol: they have anti-inflammatory activity by switching genes on and off, resulting in a reduction of inflammatory cytokines and chemokines. Corticosteroids have an effect on structural cells of the respiratory tract: they act on epithelial cells by inhibiting transcription factors such as NF-kB, on mucous glands by decreasing mucus secretion, and on smooth muscle cells by increasing β2 receptors .",
"Title: Key mechanisms governing resolution of lung inflammation\nPassage: Despite ongoing controversy, glucocorticoids remain the best studied anti-inflammatory strategy in ARDS. There is some evidence to suggest that given early in disease course, intravenous steroids reduce requirement for mechanical ventilation, length of ITU stay and improve oxygenation, with a modest effect on mortality . Such success is, however, only likely to outweigh potential complications in the setting of vigilant surveillance for nosocomial infection and eschewal of neuromuscular blockade due to the potential complications of steroid treatment. Furthermore, it has been suggested that if left to later time points, i.e. >14 days postonset, steroid administration may cause a paradoxical increase",
"Title: New aspects in the management of pneumonia\nPassage: may be useful for reducing inflammation and may not cause so much harm by producing immunosuppression. Moreover, a short period of corticosteroid treatment may reduce the risk for side effects."

"Title: New aspects in the management of pneumonia\nPassage: The main side effects associated with corticosteroids, especially with prolonged use, are hyperglycemia, myopathy, weight gain, brushing, and osteopenia . As well as these side effects, corticosteroids have strong immunosuppressive effects, raising concerns regarding their use in acute infections, despite their potential effect in controlling excessive inflammatory response. The immunosuppressant effect of corticosteroids is related to dose and treatment duration. For example, the use of 40 mg of prednisolone per day for more than 1 week or 20 mg prednisolone or equivalent per day for a month can produce immunosuppression. In acute infection, a low dose for a short period",
"Title: New aspects in the management of pneumonia\nPassage: Glucocorticosteroid drugs reproduce effects similar to endogenous cortisol: they have anti-inflammatory activity by switching genes on and off, resulting in a reduction of inflammatory cytokines and chemokines. Corticosteroids have an effect on structural cells of the respiratory tract: they act on epithelial cells by inhibiting transcription factors such as NF-kB, on mucous glands by decreasing mucus secretion, and on smooth muscle cells by increasing β2 receptors .",
"Title: Key mechanisms governing resolution of lung inflammation\nPassage: Despite ongoing controversy, glucocorticoids remain the best studied anti-inflammatory strategy in ARDS. There is some evidence to suggest that given early in disease course, intravenous steroids reduce requirement for mechanical ventilation, length of ITU stay and improve oxygenation, with a modest effect on mortality . Such success is, however, only likely to outweigh potential complications in the setting of vigilant surveillance for nosocomial infection and eschewal of neuromuscular blockade due to the potential complications of steroid treatment. Furthermore, it has been suggested that if left to later time points, i.e. >14 days postonset, steroid administration may cause a paradoxical increase",

"Title: In Vitro Antiviral Activity of Circular Triple Helix Forming Oligonucleotide RNA towards Feline Infectious Peritonitis Virus Replication\nPassage: Vaccination against FIPV with an attenuated, temperature-sensitive strain of type II FIPV induces low antibody titre in kittens that have not been exposed to FCoV. However, there is considerable controversy on the safety and efficacy of this vaccine, since the vaccine contains type 2 strain, whereas type 1 viruses are more prevalent in the field . In addition, antibodies against FIPV do not protect infected cats but enhance the infection of monocytes and macrophages via a mechanism known as Antibody-Dependent Enhancement .

"Title: Avipoxviruses: infection biology and their use as vaccine vectors\nPassage: In the poultry industry, prophylactic measures against FWPV are achieved primarily by vaccination with live FWPV or antigenically similar pigeonpox virus strains produced in CEF cells . In the past two decades, numerous outbreaks have been reported in vaccinated flocks, suggesting that vaccines used against the disease were not effective. In the United States a commercial FWPV vaccine was shown to be contaminated with REV and caused lymphoma among broiler chickens . It has been shown that sequences of REV have been integrated into the DNA of FWPV vaccines as well as in field FWPV isolates . The integration site",

Vaccination is the main prophylactic method of preventing FMDV infection. Many types of vaccines have been designed-almost entirely parenterally administered-including inactivated antigen vaccines, live attenuated vaccines, DNA vaccines, empty capsid vaccines and synthetic peptide vaccines . Inactivated virus vaccines can elicit high levels of neutralizing antibodies and offer efficacious protection against homologous serotypes . However, these vaccines",
