Abstract Background Most research on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants focuses initial symptomatology with limited longer-term data. We characterized prevalences of prolonged symptoms 3 months post–SARS-CoV-2 infection across variant time-periods (pre-Delta, Delta, and Omicron). Methods This multicenter prospective cohort study adults illness tested for SARS-CoV-2 compared fatigue severity, symptoms, organ system–based ≥3 among participants a positive...

The prevalence, incidence, and interrelationships of persistent symptoms after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection vary. There are limited data on specific phenotypes symptoms. Using latent class analysis (LCA) modeling, we sought to identify whether COVID-19 were present 3 months 6 post-infection.
Direct electronic access to multiple health record (EHR) systems through patient portals offers a novel avenue for decentralized research. Given the critical value of characterization, we sought compare computable evaluation conditions from patient-portal EHR against traditional self-report. In nationwide Innovative Support Patients with SARS-CoV-2 Infections Registry (INSPIRE) study, which linked self-reported questionnaires multiplatform data, compared across different clinical domains...

Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiological (PRG) are commonly utilized to establish access enteral nutrition. However, data comparing the outcomes of PEG vs. PRG conflicting. Therefore, we aimed conduct an updated systemic review meta-analysis outcomes.Medline, Embase, Cochrane library databases were searched until February 24, 2023. Primary included 30-day mortality, tube leakage, dislodgement, perforation, peritonitis. Secondary bleeding, infectious...
