Monocyte distribution width as a pragmatic screen for SARS-CoV-2 or influenza infection.
The purpose of this prospective cohort analysis was to determine the performance of Monocyte distribution width (MDW) and other leukocyte parameters as screening tests for SARS-CoV-2 and influenza infection. Researchers conducted an observational study with a cohort analysis consisting of adult patients who underwent complete blood count (CBC) and SARS-CoV-2 or influenza testing in an Emergency Department (ED) between January 2020 and July 2021. The study concluded that MDW, when available as part of a routine complete blood count (CBC) with differential, could be a useful indicator of SARS-CoV-2 or influenza infection.

Influenza testing and treatment among patients hospitalized with community-acquired pneumonia.
This study looked at testing rates for influenza in hospitalized patients admitted for community-acquired pneumonia (CAP) and whether it is associated with antiviral treatment and shorter antibiotic courses. The study included patients admitted in 179 US hospitals with pneumonia from 2010 to 2015. The authors assessed influenza testing and compared antimicrobial utilization and the outcomes of test-positive, test-negative, and untested patients. Among 166,268 patients with CAP, 23.3% were tested for influenza, of whom 11.5% tested positive. Testing increased from 15.4% to 35.5% from 2010 to 2015 and was more than triple the rate during flu season (October-May) vs June to September. Patients who tested positive for influenza received antiviral agents more often and antibiotics less often and for shorter courses than patients testing negative. Patients who received early antiviral treatment with oseltamivir experienced lower 14-day in-hospital mortality, lower costs, and shorter length of stay vs patients receiving oseltamivir later or not at all.

Influenza vaccination in Massachusetts jails: a mixed-methods analysis.
The objectives of this study were to survey health administrators in Massachusetts county jails about institutional influenza vaccine policies and practices and estimate influenza vaccination rates in Massachusetts jails from 2013 to 2020. Findings showed that influenza vaccination rates in Massachusetts jails were low, and delivery practices in jails varied. The authors noted that lack of influenza vaccinations in jails is a gap in health care that needs to be prioritized, especially considering the current COVID-19 pandemic. They suggested that further investigations for effective and equitable vaccination in this population should involve people who are incarcerated and people who make influenza vaccine policies in jails.

Severity of hospitalizations from SARS-CoV-2 vs influenza and respiratory syncytial virus infection in children aged 5 to 11 years in 11 US states.
By the time emergency use authorization had been granted for the Pfizer-BioNTech vaccine in October 2021 in children aged 5 to 11 years, there had been 1.8 million diagnoses of SARS-CoV-2 infection, 8,000 hospitalizations, and 143 deaths in that age group. Very little has been reported on the severity of those hospitalizations relative to the influenza virus and respiratory syncytial virus (RSV) which are the most common childhood viruses. The purpose of this study was to compare hospitalizations of children aged 5 to 11 for SARS-CoV-2 infection and multisystem inflammatory system in children (MIS-C, a sequela of COVID-19 disease) with the hospitalizations of children aged 5 to 11 years who were infected with influenza and RSV. The researchers utilized inpatient data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project from the first 11 states with complete first-quarter data as of October 2021, representing 24% of the US population of children aged 5 to 11 years. The researchers examined 46 complications in 7 body systems, total care costs and charges, and data on race and ethnicity. The resulting cross-sectional study included patient data from a total of 2,269 children. The study found that COVID-19 hospitalizations occurred at the rate of 10.8 per 100,000 children, while Influenza and RSV were rare during the first quarter of 2021 with 23 total hospital discharges combined. However, in 2017, which researchers also measured for data on influenza and RSV, influenza and RSV had 17.0 and 6.2 hospitalizations per 100,000 children, respectively. Inpatient death for all viruses was rare. MIS-C had the highest rates of cardiovascular, hematologic, and gastrointestinal complications. Children with RSV ha the highest rate of respiratory complications. Children with COVID-19 (without MISC-C) had the highest rate of neurologic complications, whereas children with influenza had the highest rate of muscoskeletal complications. Children with MIS-C had the longest median length of stay at a median cost of $23,585 per stay compared to children with influenza with a median length of stay of 2 days and a cost of $5,200.

Bacterial coinfection in influenza pneumonia: rates, pathogens, and outcomes.
Among patients hospitalized for influenza pneumonia, the researchers reported the rate of coinfection and distribution of pathogens and also compared outcomes of patients with and without bacterial coinfection. They found that, in a large US inpatient sample hospitalized with influenza and community-acquired pneumonia, Staphylococcus aureus was the most frequent cause of bacterial coinfection. Coinfection was associated with worse outcomes and higher costs.
