TWiV provides an update on hepatitis of unknown etiology in children, an experimental nanoparticle vaccine for Epstein-Barr virus, and minimal impact of bamlanivimab therapy on antiviral antibodies induced by vaccination.
In COVID-19 clinical update #119, Dr. Griffin reviews tixagevimab for infection prevention, ivermectin for outpatient infection treatment, symptom rebound after PAXLOVID treatment, bamlanivimab minimally impacting immune response to vaccination, in-hospital mortality among infection patients, residual viral antigen in patients following infection, usage of Casirvimab/Imdevimab and Remdesivir in infected patients with depleted B-cells, and rheumatic symptoms following infection.
In COVID-19 clinical update #118, Dr. Griffin discusses management of hair loss after infection, FDA announcements on vaccine schedule and recommendations, Moderna announcement on bivalent booster candidate, association between vaccination and infection during pregnancy, population-level implications of Israel’s booster campaign, PAXLOVID outcomes during recent infection surge, efficacy and safety of Tixagevimab-cilgavimab, diagnostic accuracy of infection by canines, efficacy of colchicine in hospitalized patients, and factors associated with hospital readmission.
TWiV reviews human monkeypox infections, evidence for human Mimivrus infections, and incidence of long COVID in post-vaccine SARS-CoV-2 infections.
In COVID-19 clinical update #117, Dr. Griffin discusses duration of virus shedding, association between pre-exposure to steroids and infection outcome, post-infection subtypes, rehabilitation for post-acute infection, Tixagevimab/Cilgavimab for infection prevention, antibody prophylaxis and vaccination in kidney transplant recipients, remdesivir and bebtelovimab fact sheets for providers, the updated guidelines on treatment with Famotidine, Paxlovid rebound symptom characterizations, antigen test positivity duration, viral dynamics of variants and isolation, association of inflammation in CS fluid, and transmission dynamics in Ghana.
In COVID-19 clinical update #115, Dr. Griffin discusses croup association with infection surge, rhinovirus co-circulation in children, shedding following vaccination, high vaccine efficacy in children 6 mo-5 yr, vaccine protection for hospitalized patients, convalescent plasma as post-exposure prophylaxis, real-world effectiveness of PAXLOVID, effectiveness of PAXLOVID in reducing hospitalization, infection rebound after PAXLOVID, relapse of symptomatic infection after PAXLOVID, remdesivir and bebtelovimab fact sheets for providers, guidelines on usage of anticoagulation drugs, long covid symptoms after vaccination, excess mortality in MA, infection sequelae and immunity, and post infection conditions among adults.
TWiV reviews recent cases of monkeypox, presence of SARS-CoV-2 RNA but not infectious virus in feces, and the association of autoantibodies to interferons with severe COVID-19.
In COVID-19 clinical update #115, Dr. Griffin reviews cross-variant immunity without vaccination, EUA for boosters in 5-11 year olds, B.1.1.529 attack rate, scent dogs, Omicron and pets, Paxlovid, Veklury, Fluvoxamine, antigen positivity after isolation, inflammasome activation and severe disease, and GI persistence and fecal shedding.
TWiV celebrates 900 episodes, Vincent gives the Richard R. Ernst lecture, and we discuss why inflammasome activation in infected macrophages drives severe COVID-19. Hosts: Vincent Racaniello, Alan Dove, Rich Condit, Kathy Spindler, and Brianne Barker Click…
n COVID-19 clinical update #114, Dr. Griffin discusses early treatment with ivermectin, procalcitonin not a reliable biomarker, vaccine in 6-11 year olds, FDA limits use of Janssen vaccine, does site of vaccine booster matter, sniffer dogs, monoclonals for hospitalized patients, risk assessment for public events, Paxlovid eligibility, and persistence of pediatric anosmia,
