The revised Approved Instructional Resources score: An improved quality evaluation tool for online educational resources.

Background: Free Open-Access Medical education (FOAM) use among residents continues to rise. However, it often lacks quality assurance processes and residents receive little guidance on quality assessment. The Academic Life in Emergency Medicine Approved Instructional Resources tool (AAT) was created for FOAM appraisal by and for expert educators and has demonstrated validity in this context.

Simulation-Based Mastery Learning Improves Ultrasound-Guided Peripheral Intravenous Catheter Insertion Skills of Practicing Nurses.

Introduction: Difficult intravenous (IV) access (DIVA) is frequently encountered in the hospital setting. Ultrasound-guided peripheral IV catheter (USGPIV) insertion has emerged as an effective procedure to establish access in patients with DIVA. Despite the increased use of USGPIV, little is known about the optimal training paradigms for bedside nurses.

Difficult intravenous access in the emergency department: Performance and impact of ultrasound-guided IV insertion performed by nurses.

Background: Difficult intravenous access (DIVA) is a common problem in Emergency Departments (EDs), yet the prevalence and clinical impact of this condition is poorly understood. Ultrasound-guided peripheral intravenous catheter (USGPIV) insertion is a successful modality for obtaining intravenous (IV) access in patients with DIVA.

Objectives: We aimed to describe the prevalence of DIVA, explore how DIVA affects delivery of care, and determine if nurse insertion of USGPIV improves care delays among patients with DIVA.

Left Ventricular Assist Device Management in the Emergency Department.

The prevalence of patients living with a left ventricular assist device (LVAD) is rapidly increasing due to improvements in pump technology, limiting the adverse event profile, and to expanding device indications. To date, over 22,000 patients have been implanted with LVADs either as destination therapy or as a bridge to transplant. It is critical for emergency physicians to be knowledgeable of current ventricular assist devices (VAD), and to be able to troubleshoot associated complications and optimally treat patients with emergent pathology.

Differential effects of cocaine exposure on the abundance of phospholipid species in rat brain and blood.

Background: Lipid profiles in the blood are altered in human cocaine users, suggesting that cocaine exposure can induce lipid remodeling.

Methods: Lipid changes in the brain tissues of rats sensitized to cocaine were determined through shotgun lipidomics using electrospray ionization-mass spectrometry (ESI-MS). We also performed pairwise principal component analysis (PCA) to assess cocaine-induced changes in blood lipid profiles.
