Post-acute sequelae of COVID-19 (PASC) represent an emerging global crisis. However, quantifiable risk factors for PASC and their biological associations are poorly resolved. We executed a deep multi-omic, longitudinal investigation 309 patients from initial diagnosis to convalescence (2-3 months later), integrated with clinical data patient-reported symptoms. resolved four PASC-anticipating at the time diagnosis: type 2 diabetes, SARS-CoV-2 RNAemia, Epstein-Barr virus viremia, specific...

Abstract Risk stratification for hospitalized adults with COVID-19 is essential to inform decisions about individual patients and allocation of resources. So far, risk models severe COVID outcomes have included age but not been optimized best serve the needs either older or younger adults. Models also need be updated reflect improvements in treatments. This retrospective study analyzed data from 6906 a community health system across five states western United States. were developed predict...

Objective There is uncertainty around the safety of SSRIs for treating depression during pregnancy. Nevertheless, use has been gradually increasing, especially COVID-19 pandemic period. We aimed to (1) characterize maternal rate and in a recent 10-year period, (2) address confounding by indication, as well socioeconomic environmental factors, (3) evaluate associations timing SSRI exposure pregnancy with risk preterm birth (PTB), low birthweight (LBW), small gestational age (SGA) infants...

Here, we present a comprehensive response map spanning 454 proteins 847 metabolites plasma integrated with single-cell multi-omic assays of PBMCs which whole transcriptome, 192 surface proteins, T B cell receptor sequence were co-analyzed within the context clinical measures from 50 COVID19 patient samples. Our study reveals novel cellular subpopulations,...

Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin-II receptor blockers (ARB), the most commonly prescribed antihypertensive medications, counter renin-angiotensin-aldosterone system (RAAS) activation via induction of angiotensin-converting 2 (ACE2) expression. Considering that ACE2 is functional for SARS-CoV-2 entry into host cells, association ACEi ARB with COVID-19 outcomes needs thorough evaluation.We conducted retrospective analyses using both unmatched propensity score...
