There were 133 (19.8%) errors identified. Ten errors (1.6%) occurred at the CSC and 123 (18.2%) errors occurred at regional hospitals. More patients who had an error with alteplase administration (12.7%) experienced a hemorrhagic conversion compared to those with no error in administration (7.2%, p= 0.04).

The error rate of alteplase infusion for ischemic stroke is high, particularly in patients from referring centers. Errors may be associated with adverse events. Further education and administration safeguards should be implemented to decrease the risk of medication errors.

Despite its increasing popularity among providers, it has a well-known narrow therapeutic window which can lead to delayed onset of symptoms with extended-release formulations and devastating consequences in overdose. We have noticed some patients misusing bupropion via intravenous use and had difficulty guiding decisions regarding clinical monitoring in these patients. As this route entirely changes the kinetics of bupropion, this has caused concern within our group. We reviewed all the cases of intravenous bupropion use reported to a single poison center without any other coingestants. The majority (66.7%) of patients had moderate effects and one patient had a seizure. No deaths were reported. All patients were symptomatic by the time of initial call to the poison center if they had any reported symptoms due to bupropion. This case series describes the clinical effects reported, and the timing of these effects, after intravenous bupropion use.

Concussions and chronic traumatic encephalopathy (CTE) related to professional football has received much attention within emergency care and sports medicine. Research suggests that some of this may be due to a greater likelihood of initial helmet contact (IHC), however this association has not been studied across all age groups. This study aims to investigate the association between player age and IHC in American football.

Retrospective review of championship games between 2016 and 2018 at 6 levels of amateur tackle football as well as the National Football League (NFL). Trained raters classified plays as IHC using pre-specified criteria. A priori power analysis established the requisite impacts needed to establish non-inferiority of the incidence rate of IHC across the levels of play.

Thirty-seven games representing 2912 hits were rated. The overall incidence of IHC was 16% across all groups, ranging from 12.6% to 18.9%. All but 2 of the non-NFL divisions had a statistically reduced risk of IHC when compared with the NFL, with relative risk ratios ranging from 0.55-0.92. IHC initiated by defensive participants were twice as high as offensive participants (RR 2.04, p < 0.01) while 6% [95% CI 5.4-7.2] of all hits were helmet-on-helmet contact.

There is a high rate of IHC with a lower relative risk of IHC at most levels of play compared to the NFL. Further research is necessary to determine the impact of IHC; the high rates across all age groups suggests an important role for education and prevention.

With over five drug classes FDA approved in the last decade, the significant advancements in the pharmacologic management of PAH has improved long-term outcomes. Drug therapies have been developed to directly target the underlying pathogenesis of PAH including phosphodiesterase type-5 inhibitors (PDE-5i), endothelin-receptor antagonists (ERAs), guanylyl-cyclase inhibitors, prostacyclin analogues, and prostacyclin receptor agonists. Although these agents offer remarkable benefits, there are significant challenges with their use such as complexities in medication dosing, administration, and adverse effects. Given these consequences, PAH medications are classified as high-risk, and the transitions of care process to and from the hospital setting are a vulnerable area for medication errors in this population. Thus, it is crucial for the emergency department provider to appropriately identify, manage, and triage these patients through close collaboration with a multidisciplinary team to ensure safe and effective medication management for PAH patients in the acute care setting.The aortic arch aneurysm is a complex disease that requires branching of one or more aortic arch vessels and can be fatal if left untreated. In this in vitro study, we examine the effect of the treatment approach on the unsteady hemodynamics and blood perfusion to the upper vessel’s in models of an aortic arch aneurysm, and of the three common repair approaches open-chest surgical repair, chimney, and hybrid approach. A particle image velocimetry method was used to quantify the unsteady hemodynamics in the four models simulated in a mock circulatory loop, to evaluate unsteady hemodynamic parameters and measure perfusion to the brain and the upper body. According to the findings, in terms of perfusion to the brain and upper body, the surgery model has the highest flow rate comparing to the other models in most heart-rate conditions. It also shows oscillatory parameters in the upper vessels which in normal arteries are correlated with a better arterial function. see more Between the two endovascular procedures, the hybrid model exhibits slightly better hemodynamic characteristics than the chimney model, with lower shear stresses and more oscillatory flow and WSS in the upper vessels. The hybrid model had lower perfusion flow rates to upper vessels during rest conditions (90BPM). However, unlike the other models, perfusion in the hybrid model increased with heart rate, thus at 135 BPM, it results in flow rate to upper vessels similar to that of the chimney model. The results of this study may shed light on future endograft’ design and placement techniques.
