Temporal Dynamics and (Para)Clinical Factors Associated With (Long) Viral RNA Shedding in COVID-19 Nonhospitalized Individuals - The COVID-HOME Study.

Understanding temporal patterns and determinants of RNA shedding is important to comprehend SARS-CoV-2 transmission and improve biosafety/isolation guidelines. Nonhospitalized SARS-CoV-2-infected individuals and household members were enrolled between March 2020 and June 2021 and followed prospectively ≥ 3 weeks during acute disease and at 3-, 6-, 12-, and 18-months to obtain (para)clinical data and biospecimens. Flow cytometry-based surrogate assay (FlowSA) detected viable SARS-CoV-2.

Investigating a New Way to Assess Metabolic Risk in Pregnant Females with Prior RYGB Surgery.

Background: Obesity in pregnancy is linked to adverse clinical outcomes such as gestational diabetes. Recently, a risk score calculated by different ceramide concentrations was recognized as a new way to investigate cardiovascular risk. The aim was to analyze if the ceramide risk score and cardiometabolic risk vary between normal-weight, obese, and females with prior Roux-en-Y bypass surgery (RYGB) during pregnancy.

Molecular epidemiology of a Parainfluenza Type 3 virus outbreak: Informing infection control measures on adult hematology wards.

Objectives: Parainfluenza virus type 3 (PIV3) outbreaks among hematology patients are associated with high morbidity and mortality. Prompt implementation of infection prevention (IP) measures has proven to be the most efficacious approach for controlling PIV3 outbreaks within this patient population. The most suitable IP measures can vary depending on the mode of virus transmission, which remains unidentified in most outbreaks.

Changes in enterovirus epidemiology after easing of lockdown measures.

Introduction: Public health measures aimed at controlling transmission of SARS-CoV-2, otherwise known as "lockdown" measures, had profound effects on circulation of non-SARS viruses, many of which decreased to very low levels.  The interrupted transmission of these viruses may have lasting effects. Some of the influenza clades seem to have disappeared during this period, a phenomenon which is described as a "funnel effect".
