Multicenter Study Clinical Trial
Sharing and Teaching Electrocardiograms to Minimize Infarction (STEMI): reducing diagnostic time for acute coronary occlusion in the emergency department.
Limits to ST-Elevation Myocardial Infarction (STEMI) criteria may lead to prolonged diagnostic time for acute coronary occlusion. We aimed to reduce ECG-to-Activation (ETA) time through audit and feedback on STEMI-equivalents and subtle occlusions, without increasing Code STEMIs without culprit lesions. ⋯ There were 51 culprit lesions in the baseline period, and 64 in the intervention period. Median ETA declined from 28.0 min (95% confidence interval [CI] 15.0-45.0) to 8.0 min (95%CI 6.0-15.0). The website garnered 70.4 views/week and 27.7 visitors/week in a group of 80 physicians. There was no change in percentage of Code STEMIs without culprit lesions: 28.2% (95%CI 17.8-38.6) to 20.0% (95%CI 11.2-28.8%). Conclusions Our novel weekly web-based feedback to all emergency physicians was associated with a reduction in ETA time by 20 min, without increasing Code STEMIs without culprit lesions. Local ECG audit and feedback, guided by ETA as a quality metric for acute coronary occlusion, could be replicated in other settings to improve care.

Randomized Controlled Trial
How does the side of approach impact the force delivered during external chest compression?
We investigated the biomechanics of four external chest compression (ECC) approaches involving different sides of approach and hand placement during cardiopulmonary resuscitation (CPR). ⋯ The higher differences in pressure and force under the LsLc and RsRc approaches may lead to higher risks of potential injury. When performing standard-quality ECC, the LsRc and RsLc approaches, in which compression pressure and force are better distributed, may be more suitable than RsRc or LsLc.

Guidelines for neonatal resuscitation recommend a 3:1 compression to ventilation ratio. However, this recommendation is based on expert opinion and consensus rather than strong scientific evidence. Our primary aim was to assess whether continuous chest compressions with asynchronous ventilations would increase return of spontaneous circulation (ROSC) rate and survival compared to the 3:1 chest compression to ventilation ratio. ⋯ Continuous chest compressions with asynchronous ventilations significantly improved CPP, ETCO2, time to ROSC, ROSC at 30 s and survival in a porcine model of neonatal resuscitation.

Cannabidiol (CBD) has become a popular supplement in consumer products in recent years, resulting in part from normalization of the cultivation of low THC cannabis in 2018. However, the actual content of CBD-labeled products is frequently uncertain, as oversight of such products is minimal. To date, there is little pragmatic knowledge regarding exposures to products labeled as containing CBD. ⋯ Cases reported to Poison Control Centers regarding exposures to CBD-labeled products have been increasing, representing an emerging trend of interest to Poison Control Center professionals, clinicians, and public health officials. Further monitoring of this trend is recommended.

Fever and low back pain with radicular symptoms raise concern for epidural abscess or other neuraxial infection, especially in the context of recent epidural anesthesia. Here we present an unusual case with several confounding factors and an unexpected diagnosis.
