Characterizing #COVID-19 and #Influenza Illnesses in the Real World via Person-Generated Health Data

The fight against COVID-19 is hindered by similarly presenting viral infections that may confound detection and monitoring. We examined Person-generated Health Data (PGHD), consisting of survey and commercial wearable data from individuals’ everyday lives, for 230 people who reported a COVID-19 diagnosis between 2020-03-30 and 2020-04-27 (N=41 with wearable data). Compared to self-reported diagnosed flu …

Distinct #inflammatory profiles distinguish #COVID-19 from #influenza with limited contributions from #cytokine storm

We pursued a study of immune responses in COVID-19 and influenza cohorts. Compared to influenza patients, COVID-19 patients exhibited largely equivalent lymphocyte counts, fewer monocytes, and lower surface HLA-class II expression on select monocyte populations. Furthermore, decreased HLA-DR on intermediate monocytes was a significant predictor of COVID-19 disease severity. In contrast to prevailing assumptions about …

Association of postoperative #influenza vaccine on overall mortality in patients undergoing curative surgery for solid #tumors

Recent findings have found that the influenza vaccine induces changes in the immune system in favor of anti‐tumor cytotoxicity. The aim in this study was to investigate if an influenza vaccine given in the postoperative period decreased overall and cancer‐specific mortality in patients undergoing curative surgery for solid cancers. We conducted a registry‐based national observational …

Association of acute myocardial #infarction with #influenza: A nationwide observational study

Influenza may precipitate cardiovascular disease, but influenza typically peaks in winter, coinciding with other triggers of myocardial infarction (MI) such as low air temperature, high wind velocity, low atmospheric pressure, and short sunshine duration.. Weekly laboratory-confirmed influenza case reports were obtained from the Public Health Agency of Sweden from 2009 to 2016 and merged with …

Baloxavir Marboxil for Prophylaxis against Influenza in Household Contacts

Baloxavir marboxil (baloxavir) is a polymerase acidic protein (PA) endonuclease inhibitor with clinical efficacy in the treatment of uncomplicated influenza, including in outpatients at increased risk for complications. The postexposure prophylactic efficacy of baloxavir in the household setting is unclear.. ..A total of 752 household contacts of 545 index patients were randomly assigned to receive …
