Development And Implementation Of An Evidence Based Practice Guideline Related To The Management Of Adult Angioedema, Megan Przybysz

Doctor of Nursing Practice Scholarly Projects

Angioedema (AE) is a potentially life-threatening medical condition that occurs with a higher frequency than medical providers may expect, with the emergency department (ED) serving as the usual first point of medical contact for patients. Any hesitation in recognizing AE or inconsideration of the disease process in differential diagnoses may lead to a dangerous delay of care. Due to the potential rapid progression of airway obstruction in AE, inexperienced providers should not attempt intubation, instead deferring to providers experienced in alternative airway techniques (i.e., anesthesia providers). The primary goal of this project is to develop an evidencebased practice guideline for …

Electronic cigarettes are battery powered devices that use a vape-liquid to produce a vapor that is inhaled. A consequence of the rise in e-cigarette usage was the 2019 emergence of a vaping-induced respiratory disease denoted as 'e-cigarette or vaping use-associated lung injury' (EVALI). One of the suspected causes of EVALI is Vitamin E Acetate (VEA), which was found to be a diluent in certain illicit vape-pens, whereas nicotine is commonly diluted in equal parts propylene glycol and vegetable glycerin (PG:VG). The prevalent use of e-cigarettes and the emergence of a novel illness has made understanding how e-cigarette vapors affect our …

Surface-enhanced Raman spectroscopy (SERS) is an ultrasensitive spectroscopic technique that generates signal-enhanced fingerprint vibrational spectra of small molecules. However, without rigorous control of SERS substrate active sites, geometry, surface area, or surface functionality, SERS is notoriously irreproducible, complicating the consistent quantitative analysis of small molecules. While evaporatively prepared samples yield significant SERS enhancement resulting in lower detection limits, the distribution of these enhancements along the SERS surface is inherently stochastic. Acquiring spatially resolved SERS spectra of these dried surfaces, we have shown that this enhancement is governed by a power law as a function of analyte concentration. Consequently, by definition, …

Falls account for >$50 billion of medical spending in 2015 (CDC). Real-time haptic feedback shows promise at reducing static standing COM sway (Meszaros, 2019). Pilot data variability suggests that some haptic-wearers ‘over-correct’ (unnecessarily reducing available degrees of freedom), when haptic correction is perceived as ‘a mistake. Does over-correction reduce multi-segment control and impair sway stability (Hsu, Scholz, et al. 2007)?

Student-Faculty Research - College of Physical Therapy

Challenging older adults to execute peak effort functional tests is not common. A peak effort test pushes patients to the point of not sustaining the task. The Wingate test is a peak effort test that measures the amount of revolutions per second a participant can perform over 30s. Older adults with knee osteoarthritis (OA) may regulate their effort during the Wingate. Alternatively, high exertion during the Wingate test may yield high value in influencing attitudes related to pain and aging. The purpose of this study was to develop themes of what influences peak effort during the Wingate test in participants …
