A recent academic-government partnership demonstrated the feasibility of utilizing Emergency Departments (ED) as a primary site for subject enrollment in clinical trials and achieved high rates of recruitment in two U.S. EDs. Given the ongoing need to test new therapeutics for influenza and other emerging infections, we sought to describe the historical rates of participant recruitment into influenza Phase III therapeutic RCTs in various clinical venues, including EDs. ⋯ Published RCTs evaluating influenza therapeutics in clinical settings recruit participants from multiple sites but enroll relatively few participants, per site, per season. The few ED-based studies reported recruited more subjects per site per season. Untapped opportunities likely exist for EDs to participate and/or lead therapeutic RCTs for influenza or other emerging respiratory pathogens.

Anaphylaxis is a potentially life-threatening condition that occurs in the emergency department (ED). Although anaphylaxis is rapidly recognized and treated in the hospital compared with that in the community, in some cases, it does not respond to proper management. ⋯ We present our case series to highlight the risk of developing refractory anaphylaxis with subsequent in-hospital cardiac arrest. Patients may progress to cardiac arrest within minutes despite prompt recognition and management. If patients present with potentially fatal symptoms, a more aggressive approach, including intravenous adrenaline infusion, should be taken.

In former studies, the arterio-alveolar carbon dioxide gradient (ΔCO2) predicted in-hospital mortality after initially survived cardiac arrest. As early outcome predictors are urgently needed, we evaluated ΔCO2 as predictor for good neurological outcome in our cohort. ⋯ ΔCO2 at admission after a successfully resuscitated cardiac arrest is associated with 30 days survival with good neurological outcome. However, a higher ΔCO2 may rather be a surrogate for unfavorable resuscitation circumstances than an independent outcome predictor.

The nasopharyngeal swab is the gold standard collection method for COVID-19, but is invasive and painful, subsequently resulting in poor patient acceptance. This investigation explores the process of developing and validating an alternative respiratory pathogen collection device that relies on a nasopharyngeal irrigation mechanic. The primary objective was to determine if sufficient pathological sampling can be achieved by mechanism of nasopharyngeal irrigation that is proportionate to the nasopharyngeal swab method. ⋯ The importance of early diagnostic testing and its role in countermeasures for communicable diseases such as COVID-19 is well established in the literature. Innovation to bolster our testing infrastructure is more important now than ever. This study was successful in developing and validating an alternative nasopharyngeal respiratory pathogen collection device that utilizes fluid debridement as its core mechanic. Data from this pilot study demonstrated the study device was successful in producing high-quality specimens for PCR testing. Feedback from the study participants was also in favor of the study device when compared to the nasopharyngeal swab.

Carbon monoxide (CO) poisoning can cause serious neurological sequelae. However, there is neither effective treatment strategy nor reliable indicators to determine the prognosis of patients with CO poisoning. The present study aimed to observe the changes of neurological function score, disease severity score, cerebral oxygen utilization (O2UCc), bispectral (BIS) index and neuron-specific enolase (NSE) concentration, and to elucidate the clinical significance of these potential indicators and the neuroprotective effect of mild hypothermia on brain injury in patients with severe acute CO poisoning. ⋯ The study protocol was granted from Qingdao University Research Ethics Committee (Clinical trial registry and ethical approval number: QD81571283).
