Health disparities investigated in a primary care penicillin allergy removal pathway.

Unconfirmed penicillin allergies over time lead to poor health outcomes and increased health-care cost. Health disparities (HD) can create barriers in optimizing penicillin allergy care. The objective was to characterize HDs in our primary care-led amoxicillin challenge (PLAC) delabeling pathway within a universal coverage health care system.

Removing penicillin allergy label in a hospitalized adolescent with a remote penicillin and recent cephalosporin allergy.

β-Lactam antibiotics are widely used with increased utilization in hospitalized patients. Of this population, as high as 10-20% report an allergy to β-lactam antibiotics but <5% are at risk of developing clinically significant immunoglobulin E- or T-lymphocyte-mediated reactions. Most of the time, these reported allergies are present during an illness with no previous inquiry of their validity, which makes investigation and possible removal of this allergy label a challenge.

Demonstration of a Transportable Fabry-Pérot Refractometer by a Ring-Type Comparison of Dead-Weight Pressure Balances at Four European National Metrology Institutes.

Fabry-Pérot-based refractometry has demonstrated the ability to assess gas pressure with high accuracy and has been prophesized to be able to realize the SI unit for pressure, the pascal, based on quantum calculations of the molar polarizabilities of gases. So far, the technology has mostly been limited to well-controlled laboratories. However, recently, an easy-to-use transportable refractometer has been constructed.
