Randomized Controlled Trial
Oral 5-Day Lefamulin for Outpatient Management of Community-Acquired Bacterial Pneumonia: Post-hoc Analysis of the Lefamulin Evaluation Against Pneumonia (LEAP) 2 Trial.
Safe and effective oral antibiotics are needed for outpatient management of moderate to severe community-acquired bacterial pneumonia (CABP). ⋯ These data suggest that 5 days of oral lefamulin can be given in lieu of fluoroquinolones for outpatient treatment of adults with CABP and PORT risk class III/IV or CURB-65 scores of 2‒3.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hematologic disorder resulting from an ineffective and pathologic activation of the immune response system that may mimic common emergency department presentations, including sepsis, acute liver failure, disseminated intravascular coagulation, and flu-like illnesses such as coronavirus disease 2019 (COVID-19). ⋯ This review describes the relevant pathophysiology, common presentation findings, and a framework for risk stratification in the emergency department.

Review
Emergency Department Management of Severe Hypoxemic Respiratory Failure in Adults With COVID-19.
While emergency physicians are familiar with the management of hypoxemic respiratory failure, management of mechanical ventilation and advanced therapies for oxygenation in the emergency department have become essential during the coronavirus disease 2019 (COVID-19) pandemic. ⋯ High flow nasal cannula and noninvasive positive pressure ventilation have a more limited role in COVID-19 because of the risk of aerosolization and minimal benefit in severe cases, but can be considered. Stable patients who can tolerate repositioning should be placed in a prone position while awake. Once intubated, patients should be managed with ventilation strategies appropriate for ARDS, including targeting lung-protective volumes and low pressures. Increasing positive end-expiratory pressure can be beneficial. Inhaled pulmonary vasodilators do not decrease mortality but may be given to improve refractory hypoxemia. Prone positioning of intubated patients is associated with a mortality reduction in ARDS and can be considered for patients with persistent hypoxemia. Neuromuscular blockade should also be administered in patients who remain dyssynchronous with the ventilator despite adequate sedation. Finally, patients with refractory severe hypoxemic respiratory failure in COVID-19 should be considered for venovenous extracorporeal membrane oxygenation.

Multicenter Study
Comparing the Timeliness of Treatment in Younger vs. Older Patients with ST-Segment Elevation Myocardial Infarction: A Multi-Center Cohort Study.
ST-segment elevation myocardial infarction (STEMI) predominantly affects older adults. Lower incidence among younger patients may challenge diagnosis. ⋯ We found no statistically significant difference in D2B times between patients ≤ 50 years old and those > 50 years old. Nonwhite patients and those who smoke were disproportionately represented within the younger population. The very young and very old had higher odds of D2B times > 90 min.

BRASH syndrome, a relatively new entity, has been described in the recent literature. It is defined as a combination of bradycardia, renal failure, atrioventricular nodal blockade, shock, and hyperkalemia. Although it is apparent that clinical symptomatology includes shock, it is still unclear whether all patients will initially present with all five components mentioned in the BRASH acronym. ⋯ An elderly woman presented to our Emergency Department (ED) with hyperkalemia, acute renal failure, and metabolic acidosis with bradycardia, which was refractory to antikalemic measures and atropine. The montage of clinical features put together showed a clear picture of BRASH syndrome, which helped us to streamline the management and achieve a better patient outcome. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Renal failure with various metabolic derangements is commonly seen in the ED. We should be aware of this new clinical entity, as its incidence will certainly increase, and the management is a bit different. Prognosis is excellent with timely recognition and management of this rare clinical entity.
