COVID-19 was severe in the Delta variant-dominated epidemic wave (fifth wave) Japan. The clinical characteristics and effectiveness of vaccination are not fully understood Omicron (sixth seventh waves), especially hospitalized patients. We investigated relationship between disease severity Omicron-dominated compared these waves.The nationwide database (Japan Task Force) used to compare critical outcomes patients with (fifth, N = 735) vs waves (sixth, 495; seventh, 128).Patients sixth had a lower incidence respiratory outcomes, higher bacterial infection, although mortality rate did differ significantly waves. In waves, 138 (27.9%) 29 (22.7%) were unvaccinated, respectively. Multivariable analysis adjusted previously reported factors revealed that proportion (1) (2) decreased frequency-dependent manner.

ABSTRACT Background Chest computed tomography (CT) is a valuable tool for diagnosing and predicting the severity of coronavirus disease 2019 (COVID‐19) assessing extrapulmonary organs. Reduced muscle mass visceral fat accumulation are important features body composition phenotype in which obesity loss coexist, but their relationship with COVID‐19 outcomes remains unclear. In this study, we aimed to investigate association between erector spinae (ESM) epicardial adipose tissue (EAT) ratio (ESM/EAT) on chest CT patients COVID‐19. Methods We analysed data from 1074 enrolled Japan Task Force database. The primary outcome was rate critical (requiring high‐flow oxygen therapy, invasive ventilator support or death). incidence compared high low ESM/EAT ratios. Results group ( n = 353) had higher (13.3% vs. 5.13%, p < 0.001) mortality (2.55% 0.69%, 0.019) than 721). multivariable analysis, associated (adjusted odds [aOR] 2.11, 95% confidence interval [CI] 1.22–3.66) independently known factors including age, sex, index (BMI), smoking history, lifestyle‐related comorbidities pneumonia volume.

Multisystem inflammatory syndrome in adults (MIS-A) is a hyperinflammatory multisystem condition associated with coronavirus disease (COVID-19). Critically ill COVID-19 patients may develop multiorgan damage and elevated responses, thus making it difficult to differentiate between progression organ due itself or MIS-A. This study aimed explore the characteristics complications of MIS-A critical patients.
