RESUMEN
PURPOSE: Time is a critical metric in the emergency department (ED) for acute ischemic stroke and thrombolytic therapy. National guidelines have emphasized tracking time from stroke onset to treatment and decreasing door to needle (DTN) time [1, 2]. Multidisciplinary teamwork is encouraged but, there is limited evidence demonstrating the value of the pharmacist on the stroke response team. The goal of this study is to compare DTN times in the ED with or without a pharmacist at bedside and examine the impact on subsequent patient outcomes. METHODS: This was a single-center retrospective cohort study. Investigators identified patients who presented to the ED between August 2016 - May 2020 with signs of ischemic stroke and subsequently received intravenous alteplase. Patients were excluded if they refused alteplase or received alteplase off-campus before being transferred. Pharmacist documentation of clinical interventions was used to identify participation on the stroke response team. The primary outcome was median DTN time. Secondary outcomes included severity of deficits measured by the National Institutes of Health Stroke Scale (NIHSS), hospital length of stay (LOS), 90-day Modified Rankin Scale (mRS), incidence of intracranial hemorrhage (ICH), and inpatient all-cause mortality. RESULTS: Of the 164 patients included, 31 had an emergency medicine pharmacist at bedside (EMP group) and 133 did not (No EMP group). The median DTN time was significantly shorter at 35 min EMP [interquartile range (IQR) 29-44] vs 42 min No EMP [IQR 34-55]; p = 0.003. The number of cases achieving a DTN time of 30 min or less was significantly higher when a pharmacist was involved (35.5% vs.16.5%; p = 0.018) as well as the number of patients receiving alteplase within 45 min (80.7% vs. 57.1%; p = 0.015). NIHSS scores at discharge were lower in the EMP group (2 [IQR 0-5] vs. 4 [IQR 0-8.25]; p = 0.049). In patients with magnetic resonance imaging (MRI) confirmed stroke, a difference was not observed in the secondary outcomes. CONCLUSION: Patients with an emergency medicine pharmacist as part of their stroke response team had significantly lower DTN times. A higher proportion of these cases met benchmark DTN times less than 45 min and 30 min. An emergency medicine pharmacist on a stroke response team has the potential to improve patient care.

Although, green tea has numerous health benefits, adverse effects with excessive consumption have been reported. Using Drosophila melanogaster, a decrease in male fertility with green tea was evidenced. Here, the extent of green tea toxicity on development and reproduction was investigated. Drosophila melanogaster embryos and larvae were exposed to various doses of green tea polyphenols (GTP). Larvae exposed to 10 mg/mL GTP were slower to develop, emerged smaller, and exhibited a dramatic decline in the number of emerged offspring. GTP protected flies against desiccation but sensitized them to starvation and heat stress. Female offspring exhibited a decline in reproductive output and decreased survival while males were unaffected. GTP had a negative impact on reproductive organs in both males and females (e.g., atrophic testes in males, absence of mature eggs in females). Collectively, the data show that high doses of GTP adversely affect development and reproduction of Drosophila melanogaster.
