Investigation into the presence of alkaloids in single-use food-contact articles (FCA).

In this work, we have developed a method to investigate the presence of four alkaloids and their migration potential from single-use, biodegradable derived dinnerware. The seeds of palm, commonly referred to as the betel nut, are known to contain high concentrations of four alkaloids: arecoline, guvacoline, areciadine, and guvacine. Migration of these alkaloids into a food simulant was determined using a single-sided migration cell.

Machine learning of ECG waveforms and cardiac magnetic resonance for response and survival after cardiac resynchronization therapy.

Cardiac resynchronization therapy (CRT) can lead to marked symptom reduction and improved survival in selected patients with heart failure with reduced ejection fraction (HFrEF); however, many candidates for CRT based on clinical guidelines do not have a favorable response. A better way to identify patients expected to benefit from CRT that applies machine learning to accessible and cost-effective diagnostic tools such as the 12-lead electrocardiogram (ECG) could have a major impact on clinical care in HFrEF by helping providers personalize treatment strategies and avoid delays in initiation of other potentially beneficial treatments. This study addresses this need by demonstrating that a novel approach to ECG waveform analysis using functional principal component decomposition (FPCD) performs better than measures that require manual ECG analysis with the human eye and also at least as well as a previously validated but more expensive approach based on cardiac magnetic resonance (CMR).

Cardiac Magnetic Resonance, Electromechanical Activation, Kidney Function, and Natriuretic Peptides in Cardiac Resynchronization Therapy Upgrades.

As the mechanism for worse prognosis after cardiac resynchronization therapy (CRT) upgrades in heart failure patients with RVP dependence (RVP-HF) has clinical implications for patient selection and CRT implementation approaches, this study's objective was to evaluate prognostic implications of cardiac magnetic resonance (CMR) findings and clinical factors in 102 HF patients (23.5% female, median age 66.5 years old, median follow-up 4.

Impact of Pre-Advanced Pharmacy Practice Experience (APPE) Curriculum on Student Pharmacists' Professional Identity Formation.

Objective: To (1) evaluate changes in student pharmacists' professional identity during a curriculum prior to advanced pharmacy practice experiences (APPEs) and (2) describe the components of a pre-APPE curriculum that positively and negatively influenced students' professional identity formation (PIF).

Methods: The University of Washington School of Pharmacy launched a new curriculum in 2019 featuring components intentionally designed to support students' PIF. The Macleod-Clark Professional Identity Scale (MCPIS) was administered to the class of 2023 before starting pharmacy school (pre) and upon completion of the pre-APPE curriculum (post).

Noninvasive Electrical Mapping Compared with the Paced QRS Complex for Optimizing CRT Programmed Settings and Predicting Multidimensional Response.

The aim was to test the hypothesis that left ventricular (LV) and right ventricular (RV) activation from body surface electrical mapping (CardioInsight 252-electrode vest, Medtronic) identifies optimal cardiac resynchronization therapy (CRT) pacing strategies and outcomes in 30 patients. The LV80, RV80, and BIV80 were defined as the times to 80% LV, RV, or biventricular electrical activation. Smaller differences in the LV80 and RV80 (|LV80-RV80|) with synchronized LV pacing predicted better LV function post-CRT (p = 0.
