Dalbavancin Use in Persons Who Use Drugs May Increase Adherence Without Increasing Cost.

Dalbavancin (DAL) may obviate concerns regarding misuse of IV access in persons who use drugs (PWUD) completing treatment for infections in an outpatient setting. However, hesitancy to adopt its use exists due to the cost-prohibitive nature of DAL and perceived issues with insurance reimbursement. Our study looks to determine the financial impact of DAL use in actual, measured cost, and health care utilization, data as well as the effect on treatment completion rates.

Pneumococcal Urinary Antigen Testing in United States Hospitals: A Missed Opportunity for Antimicrobial Stewardship.

Background: The Infectious Diseases Society of America recommends pneumococcal urinary antigen testing (UAT) when identifying pneumococcal infection would allow for antibiotic de-escalation. However, the frequencies of UAT and subsequent antibiotic de-escalation are unknown.

Methods: We conducted a retrospective cohort study of adult patients admitted with community-acquired or healthcare-associated pneumonia to 170 US hospitals in the Premier database from 2010 to 2015, to describe variation in UAT use, associations of UAT results with antibiotic de-escalation, and associations of de-escalation with outcomes.

Activation of the Classical Mitogen-Activated Protein Kinases Is Part of the Shiga Toxin-Induced Ribotoxic Stress Response and May Contribute to Shiga Toxin-Induced Inflammation.

Infection with enterohemorrhagic Escherichia coli (EHEC) can result in severe disease, including hemorrhagic colitis and the hemolytic uremic syndrome. Shiga toxins (Stx) are the key EHEC virulence determinant contributing to severe disease. Despite inhibiting protein synthesis, Shiga toxins paradoxically induce the expression of proinflammatory cytokines from various cell types in vitro, including intestinal epithelial cells (IECs).

Managing community-acquired pneumonia during flu season.

The clinical findings of influenza overlap those of community-acquired bacterial pneumonia (CABP), and influenza infection can be complicated by bacterial infections. Reviewed here are the epidemiology, pathophysiology, diagnosis, and management of community-acquired pneumonia (CAP) with special emphasis on considerations during influenza season.
