Prescriptions frequently become the gateway to opioid misuse and abuse. In response to the opioid crisis, medical school educators in the state of Pennsylvania developed core competencies pertaining to opioids and addiction for which all medical students should demonstrate proficiency before graduation. To enable students to achieve these competencies, we developed a web-based app (IPEx) that delivers a gamified experience for learners in which they are (re)exposed to opioid competencies and practice applying pharmacologic principles in the context of a series of longitudinal patient scenarios. Learning and application are measured by student responses to application questions before and after each of five modules. Prior to launching the IPEx tool broadly, we wished to test the application questions; thus, we invited fourth year medical students to complete a 45 question quiz based on IPEx module content. Students had no specific preparation prior to taking the quiz but had been exposed to all content elsewhere in the curriculum. A total of 45 of 141 medical students (32%) opted to complete the quiz (mean score was 47% ± 13%; range 18%-73%). Cronbach alpha for the instrument was .74.

Here, we challenged rats with rapid delayed rectifier current (Ikr)-inhibiting antibiotic clarithromycin (CLA), loop diuretic furosemide (FUR) or their combination (CLA + FUR), and examined functional and molecular abnormalities after stimulation with isoproterenol. Clarithromycin and furosemide were administered orally at 12-h intervals for 7 days.

CLA and CLA + FUR treatment resulted in drug-induced LQTS and even an episode of TdP in one CLA + FUR rat. The combined treatment dysregulated gene expression of several ion channels subunits, including KCNQ1, calcium channels and Na+/K + -ATPase subunits, while both monotherapies had no impact. The rat with recorded TdP exhibited differences in the expression of ion channel genes compared to the rest of rats within the CLA + FUR group. The ECG changes were not detected in isolated perfused hearts.

It appears that many of these observations have never been exploited to construct a broad understanding and treatment of certain chronic, yet reversible, neurological illnesses.
