Approximately 20% of individuals infected with SARS-CoV-2 experienced long-term health effects, as defined PCC. However, it is unknown if there are any early biomarkers associated with PCC or whether early intervention treatments may decrease the risk of PCC. In a secondary analysis of a randomized clinical trial, this study demonstrates that among outpatients with SARS-CoV-2, increased IL-6 at time of infection is associated with increased odds of PCC. In addition, among individuals treated early, within 5 days of symptom onset, with COVID-19 convalescent plasma, there was a trend for decreased odds of PCC after adjusting for other demographic and clinical …

Cardeza Foundation for Hematologic Research

Thrombosis with thrombocytopenia syndrome (TTS) is a rare but potentially severe adverse event following immunization with adenovirus vector-based COVID-19 vaccines such as Ad26.COV2.S (Janssen) and ChAdOx1 (AstraZeneca). However, no case of TTS has been reported in over 1.5 million individuals who received a second immunization with Ad26.COV2.S in the United States. Here we utilize transcriptomic and proteomic profiling to compare individuals who receive two doses of Ad26.COV2.S with those vaccinated with BNT162b2 or mRNA-1273. Initial Ad26.COV2.S vaccination induces transient activation of platelet and coagulation and innate immune pathways that resolve by day 7; by contrast, patients with TTS show robust …

"I Just Feel Worn Out”: Constraints To Teacher Agency Throughout Covid-19, Andrew Kipp, Spencer Clark, Carl Fahrenwald, Gustavo Perez

School Leadership Review

COVID-19 created serious and long-lasting difficulties within educational systems resulting in higher rates of teacher attrition in the U.S. Teacher agency, which is the teacher’s capacity to act professionally, is a predictor of teacher attrition. The school environment, through policies and practices, can inhibit teacher agency, and the constraint of agency promotes teacher attrition. As school structures shift to address new post-pandemic needs, there is an increased need to understand how school structures throughout the pandemic inhibited teacher agency and drove teacher attrition. We examine how school systems constrained the agency of three veteran high school teachers from March 2020 …

Elevated Level Of Circulating But Not Urine S100a8/A9 Identifies Poor Covid-19 Outcomes, Leah Mellett, Gaya Amarasinghe, Christopher W Farnsworth, Shabaana A Khader

2020-Current year OA Pubs

The alarmin calprotectin (S100A8/A9) is thought to drive a cytokine storm, a hallmark of severe COVID-19. Recent studies report circulating S100A8/A9 levels can distinguish COVID-19 severity but have only been conducted in non-U.S. cohorts and mainly focus on serum S100A8/A9 levels. Thus, we quantified S100A8/A9 in serum and urine samples from a hospital cohort in St. Louis, Missouri, to expand the understanding of S100A8/A9 as a prognostic biomarker for COVID-19. Elevated S100A8/A9 serum levels were observed in ICU patients (
