We observed positive correlation between serum and salivary concentrations of all markers studied (P less then .05). CONCLUSION From the data, we conclude that investigation using saliva specimens is a noninvasive, simple, and effective tool for screening of biochemical parameters. © American Society for Clinical Pathology 2019.

If an isolation gown is ineffective, the patient and provider have a potential breach of safety and increased infection risk. This study compared the bacterial permeability of differently rated, commonly uses isolation gowns to assess their effectiveness in preventing simulated bacterial transmittance, and thus contamination, from patient to provider. METHODS Serial dilutions of Staphylococcus epidermidis in sterile saline were applied to a simulated skin surface. Unrated and Levels 1 through 4 non-sterile isolation gowns contacted the solution, simulating patient contact. Both sides of the contaminated gowns were then cultured on blood agar by rolling a sterile swab across the gown and evenly inoculating the culture plate. Colony counts from inside and outside of the gowns were compared. Separately, S. epidermidis was placed on a sample of each gown and scanning electron microscopy was used to University Press on behalf of the British Occupational Hygiene Society.The Infectious Diseases Society of America has not met their burden of proof to establish that SEP-1 has increased unnecessary antibiotic usage. Strategies recommending delay in antibiotic administration for additional diagnostics in severe sepsis have not been shown to be safe. © The Author(s) 2020. Published b
