Importance Breath analysis has been explored as a noninvasive means to detect COVID-19. However, the impact of emerging variants SARS-CoV-2, such Omicron, on exhaled breath profile and diagnostic accuracy is unknown. Objective To evaluate accuracies detecting patients with COVID-19 when SARS-CoV-2 Delta Omicron were most prevalent. Design, Setting, Participants This study included cohort who had positive negative test results for using reverse transcriptase polymerase chain reaction between...

Obesity is a risk factor for coronavirus disease 2019 (COVID-19)-related outcomes; however, the mechanism remains unclear. The objective of this analysis was to determine whether inflammation mediates association between obesity and COVID-19 outcomes. International Study Inflammation in (ISIC): A Prospective Multi-Center Observational Examining Role Biomarkers Predicting Covid-19 Related Outcomes Hospitalized Patients, conducted at 10 hospitals United States Europe. Participants were adults...

Abstract Importance Breath analysis has been explored as a non-invasive means to detect COVID-19. However, the impact of emerging variants such Omicron on exhaled breath profile and hence accuracy is unknown. Objective To evaluate diagnostic accuracies detecting COVID-19 patients in periods where Delta were most prevalent. Design, Setting, Participants A convenience cohort testing positive negative for using reverse transcriptase polymerase chain reaction (RT-PCR) studied included 167 COVID...
