Highlights•We report on a patient with a single dose of vaccine against SARS-CoV-2. •He developed relevant serum titer levels but died 4 weeks later. •By postmortem molecular mapping, we found viral RNA in nearly all organs examined. •However, we did not observe any characteristic morphological features of COVID-19. •Immunogenicity might be elicited, while sterile immunity… Continue reading First case of postmortem study in a patient vaccinated against #SARS-CoV-2

#Calcifediol treatment and #COVID-19-related outcomes
COVID-19 is a major health problem because of saturation of intensive care units (ICU) and mortality. Vitamin D has emerged as a potential treatment able to reduce the disease severity. ObjectiveTo elucidate the effect of calcifediol [25OHD3] treatment on COVID-19-related outcomes. DesignObservational cohort study from March to May, 2020. SettingPatients admitted to COVID-19 wards of… Continue reading #Calcifediol treatment and #COVID-19-related outcomes
Potential anti-COVID-19 agents, #cepharanthine and #nelfinavir, and their usage for combination treatment
Nelfinavir (NFV) inhibits SARS-CoV-2 replication•Cepharanthine (CEP) inhibits SARS-CoV-2 attachment to target cells•Combination of NFV and CEP can synergistically augment antiviral activity•NFV and CEP are estimated to shorten the time to viral elimination at clinical doses SummaryAntiviral treatments targeting the coronavirus disease 2019 are urgently required. We screened a panel of already approved drugs in a… Continue reading Potential anti-COVID-19 agents, #cepharanthine and #nelfinavir, and their usage for combination treatment
Face #masks effectively limit the probability of #SARS-CoV-2 transmission
Airborne transmission by droplets and aerosols is important for the spread of viruses. Face masks are a well-established preventive measure, but their effectiveness for mitigating SARS-CoV-2 transmission is still under debate. We show that variations in mask efficacy can be explained by different regimes of virus abundance and related to population-average infection probability and reproduction… Continue reading Face #masks effectively limit the probability of #SARS-CoV-2 transmission
Collectivism predicts #mask use during #COVID-19
Since its outbreak, COVID-19 has impacted world regions differentially. Whereas some regions still record tens of thousands of new infections daily, other regions have contained the virus. What explains these striking regional differences? We advance a cultural psychological perspective on mask usage, a precautionary measure vital for curbing the pandemic. Four large-scale studies provide evidence… Continue reading Collectivism predicts #mask use during #COVID-19
SARS-CoV-2 #Spike Protein Impairs #Endothelial Function via Downregulation of ACE 2
... SARS-CoV-2 infection induces EC inflammation, leading to endotheliitis.1,5 Because S protein decreased ACE2 level and impaired NO bioavailability, we examined whether S protein entry is indispensable for dysfunctional endothelium. As shown in Figure [F], i, the endothelium-dependent vasodilation induced by acetylcholine was impaired in pulmonary arteries isolated from Pseu-Spike-administered hamsters, whereas the endothelium-independent vasodilation… Continue reading SARS-CoV-2 #Spike Protein Impairs #Endothelial Function via Downregulation of ACE 2
Prospective Case-Control Study of #Cardiovascular Abnormalities 6 Months Following Mild #COVID-19 in Healthcare Workers
ObjectivesThe purpose of this study was to detect cardiovascular changes after mild severe acute respiratory syndrome coronavirus 2 infection.BackgroundConcern exists that mild coronavirus disease 2019 may cause myocardial and vascular disease. MethodsParticipants were recruited from COVIDsortium, a 3-hospital prospective study of 731 health care workers who underwent first-wave weekly symptom, polymerase chain reaction, and serology… Continue reading Prospective Case-Control Study of #Cardiovascular Abnormalities 6 Months Following Mild #COVID-19 in Healthcare Workers
Non-steroidal anti-inflammatory drug use and outcomes of #COVID-19 in the ISARIC Clinical Characterisation Protocol UK cohort: a matched, prospective cohort study
Early in the pandemic it was suggested that pre-existing use of non-steroidal anti-inflammatory drugs (NSAIDs) could lead to increased disease severity in patients with COVID-19. NSAIDs are an important analgesic, particularly in those with rheumatological disease, and are widely available to the general public without prescription. Evidence from community studies, administrative data, and small studies… Continue reading Non-steroidal anti-inflammatory drug use and outcomes of #COVID-19 in the ISARIC Clinical Characterisation Protocol UK cohort: a matched, prospective cohort study
MIT researchers say time spent indoors increases risk of #Covid at 6 feet or 60 feet in new study challenging social distancing policies
The risk of being exposed to Covid-19 indoors can be as great at 60 feet as it is at 6 feet in a room where the air is mixed.Existing safety guidelines have omitted too many factors to accurately quantify the risk of airborne transmission, such as time, mask use and ventilation rates.Bazant and Bush question… Continue reading MIT researchers say time spent indoors increases risk of #Covid at 6 feet or 60 feet in new study challenging social distancing policies
