Immune checkpoint inhibitors (ICIs) are a novel class of drugs used in cancer immunotherapy that are becoming more commonly used among advanced-stage cancers. Unfortunately, these therapies are sometimes associated with often subtle, potentially fatal immune-related adverse events (irAEs). ⋯ With the increasing success and popularity of ICIs, emergency physicians will inevitably encounter increasing numbers of patients on these medications as well as the associated side effects. It is important that emergency physicians become aware of these irAEs and improve the detection of these processes to prevent inappropriate discharges, emergency department revisits, and downstream complications.

Randomized Controlled Trial
End-Tidal Oxygen Saturation with Nasal Cannula During Noninvasive Positive Pressure Ventilation: A Randomized Crossover Trial.
Simultaneous use of nasal cannula (NC) with noninvasive positive pressure ventilation (NIPPV) may help streamline the transition from preoxygenation to intubation with apneic oxygenation in patients with deteriorating respiratory status, but may also compromise preoxygenation by impairing NIPPV mask seal. ⋯ The mean difference confidence interval did not include the noninferiority margin. Hence, NIPPV with NC seems noninferior to NIPPV alone with regard to EtO2. These results indicate that concomitant use of NC with NIPPV may be an appropriate preoxygenation strategy in anticipation of the potential need for transition to intubation.

Pulmonary embolism (PE) is a disease diagnosed relatively frequently in emergency departments (EDs). Evidence suggests that improved decision making may decrease inappropriate testing, unnecessary radiation exposure, and non-beneficial treatment. Several studies have looked at the utility and safety of age-adjusting the D-dimer levels used to safely rule out PE. ⋯ Age-adjusted D-dimer cutoff values, in combination with a non-high clinical probability, is safe and effective to essentially rule out PE in ED patients.
