Using AI we identified baricitinib as possessing anti-viral and anti-cytokine efficacy. We now show a 71% (95% CI 0.15-0.58) mortality benefit in 83 patients with moderate-severe SARS-CoV-2 pneumonia with few drug-induced adverse events, including a large elderly cohort (median age 81 years). A further 48 cases with mild-moderate pneumonia recovered uneventfully. Using organotypic 3D cultures… Continue reading JAK inhibition reduces #SARS-CoV-2 #liver infectivity and modulates inflammatory responses to reduce morbidity and mortality

#Dementia and the risk of death in elderly patients with #COVID‐19 infection: Systematic review and meta‐analysis
The COVID‐19 infection represents a global public health emergency worldwide. Several risk factors have been associated with a poor prognosis among COVID‐19 patients. We aimed to perform a systemic review and meta‐analysis to evaluate the mortality risk in elderly patients with dementia and COVID‐19 infection.. ..A total of 233 articles were retrieved; 158 were excluded… Continue reading #Dementia and the risk of death in elderly patients with #COVID‐19 infection: Systematic review and meta‐analysis
Preexisting and de novo humoral immunity to #SARS-CoV-2 in humans
Zoonotic introduction of novel coronaviruses may encounter preexisting immunity in humans. Using diverse assays for antibodies recognizing SARS-CoV-2 proteins, we detect preexisting humoral immunity. SARS-CoV-2 spike glycoprotein (S)-reactive antibodies were detectable by a flow cytometry-based method in SARS-CoV-2-uninfected individuals and were particularly prevalent in children and adolescents. They were predominantly of the IgG class and… Continue reading Preexisting and de novo humoral immunity to #SARS-CoV-2 in humans
Quick #COVID-19 Healers Sustain Anti-SARS-CoV-2 #Antibody Production
Antibodies are key immune effectors that confer protection against pathogenic threats. The nature and longevity of the antibody response to SARS-CoV-2 infection is not well defined. We charted longitudinal antibody responses to SARS-CoV-2 in 92 subjects after symptomatic COVID-19. Antibody responses to SARS-CoV-2 are unimodally distributed over a broad range, with symptom severity correlating directly… Continue reading Quick #COVID-19 Healers Sustain Anti-SARS-CoV-2 #Antibody Production
Neighbourhood income and physical distancing during the COVID-19 pandemic in the United States
Physical distancing has been the primary strategy to control COVID-19 in the United States. We used mobility data from a large, anonymized sample of smartphone users to assess the relationship between neighbourhood income and physical distancing during the pandemic. We found a strong gradient between neighbourhood income and physical distancing. Individuals in high-income neighbourhoods increased… Continue reading Neighbourhood income and physical distancing during the COVID-19 pandemic in the United States
Lowering the transmission and spread of human coronavirus
The emergence of the severe acute respiratory syndrome coronavirus 2 pandemic has created an unprecedented healthcare, social, and economic disaster. Wearing of masks and social distancing can significantly decrease transmission and spread, however, due to circumstances such as medical or dental intervention and personal choice these practices have not been universally adopted. Additional strategies are… Continue reading Lowering the transmission and spread of human coronavirus
Evidence that #coronavirus superspreading is #fat-tailed
Superspreaders, infected individuals who result in an outsized number of secondary cases, are believed to underlie a significant fraction of total SARS-CoV-2 transmission. Here, we combine empirical observations of SARS-CoV and SARS-CoV-2 transmission and extreme value statistics to show that the distribution of secondary cases is consistent with being fat-tailed, implying that large superspreading events… Continue reading Evidence that #coronavirus superspreading is #fat-tailed
A Time Frame for Testing Negative for SARS- #COV2 in People with #Obesity
Objective: Obesity is a major risk factor for becoming seriously ill with the 2019 novel coronavirus (COVID-19). One difficulty faced by clinicians and by patients is the unknown time frame of hospitalization until discharge of symptomatic patients. Methods: We followed 34 patients with laboratory-confirmed COVID-19 infection who recovered fromthe infection. All diagnoses were given using… Continue reading A Time Frame for Testing Negative for SARS- #COV2 in People with #Obesity
#Delirium In Severe Acute Respiratory Syndrome- #Coronavirus -2 Infection: A Point Of View
Coronavirus disease 2019 was for the first time reported in December 2019 in China, and has since spread throughout the world as a pandemic. In this point of view, we aim to discuss the occurrence of central nervous system symptomatology, and delirium, in patients suffering coronavirus disease 2019. To date, most of the research done… Continue reading #Delirium In Severe Acute Respiratory Syndrome- #Coronavirus -2 Infection: A Point Of View
