Pharmacists' perspectives on opioid stewardship challenges.

Objective: Pharmacists are in a distinctive position to champion opioid stewardship principles in communications with prescribers and patients. This effort is focused on elucidating perceived barriers to uphold these principles observed in pharmacy practice.

Design: Qualitative research study.

Methods for locating the tibio-femoral contact pathway in total knee replacements using marker-based gait analysis and standard radiography.

Introduction: The purpose of this study was to develop and test techniques for tracking the path of contact between the tibial and femoral total knee replacement components during level over-ground walking. The tibio-femoral path of contact could be an indicator of the in vivo performance of a total knee replacement as an estimator of areas of contact between the implant components. A longer contact path, indicative of more sliding between the implant components during walking, could indicate an implant at risk for increased wear.

Collaboration between allergists and pharmacists increases β-lactam antibiotic prescriptions in patients with a history of penicillin allergy.

Background: Over 90% of patients with a history of penicillin allergy have negative penicillin skin tests. Pharmacists are trained to identify and resolve medication-related problems. We hypothesized that collaboration between allergists and pharmacists to identify and evaluate patients with a history of penicillin allergy would increase β-lactam antibiotic prescription.

Calreticulin and Hsp90 stabilize the human insulin receptor and promote its mobility in the endoplasmic reticulum.

Elimination of misfolded membrane proteins in the endoplasmic reticulum (ER) affects cell survival and growth and can be triggered by either local physiologic events or disease-associated mutations. Regulation of signaling receptor degradation involves both cytosolic and ER luminal molecular chaperones, but the mechanisms and timing of this process remain uncertain. Here we report that calreticulin (CRT) and Hsp90 exert distinct effects on the stability and cell surface levels of native and misfolded forms of the human insulin receptor (hIR) and a human variant found in type A insulin resistance.
